Elektrohemijsko bromovanje estrogena i zaštićenig glikala Damljanović, Ivan, 1979- estrogen, elektrohemijsko bromovanje U ovom radu ispitane su mogućnosti primene elektrohemijskog generisanja halogena u organskoj sintezi. Kako se elementarnim halogenima organska jedinjenja mogu halogenovati na dva načina – elektrofilnim supstitucijama (aromati) i adicijama (nezasićena jedinjenja) – kao supstrati su odabrani estron (1) i estradiol (2)(za izučavanje prve reakcije) i peracetilovani glikali: 3,4,6-tri-O-acetil-D-glukal(9), 3,4,6-tri-O-acetil-D-galaktal (10) i 3,4-di-O-acetil-6-deoksi-L-glukal (11) (za izučavanje druge reakcije). In this work the possibilities of the application of an electrochemical generation of halogens in organic synthesis were investigated. Since organic compounds can be halogenated by free halogens in two ways – by electrophilic substitutions (aromatics) and additions (unsaturated compounds) – estrone (1) and estradiol (2), as well as peracetylated glycals 3,4,6-tri-O-acetyl-D-glucal (9), 3,4,6-tri-O-acetyl-D-galactal (10) and 3,4-di-O-acetyl-6-deoxy-L-glucal (11), were chosen as the substrate in order to study both reaction types. The monobromination of the A-rings of estrone and estradiol has been successfully achieved by simple constant current electrolysis of these compounds and tetraethylammonium bromide in acetic acid, dichloromethane and dimethylsulfoxide as the solvents. With the 2 Fmol−1 charge consumption electrolysis both estrogens gave two regioisomers (2- and 4-bromoestrone (4a and 4b), i.e. 2- and 4-bromoestradiol (6a and 6b))in all three solvents. The ratio of the regioisomeric bromides obtained in acetic acid and dichloromethane was 1:1.09 - 1:1.50, and the addition of water or acetanhydride to acetic acid did not affect this ratio. The bromination of estrogens by conventional methods described in the literature, that were also been conducted in the course of this study (for comparison of purposes), gave the same result and the presence of bromides during the brominations did not influence the ratio of the two regioisomers. However, both the chemical and electrochemical brominations in dimethyl sulfoxide resulted in the same product 1:2,5 -2,6. The overall yield of the both regioisomers electrochemical monobromination was very high (up to 97%).

Hidroliza peptida koji sadrže L-metionin i L-histidin pomoću različitih kompleksa paladijuma(II)i platine(II) : Živković, Marija D.,1979- Paladijum (II) kompleksi, hidroliza peptida Ispitivanja reakcija kompleksa paladijuma(II) i platine(II) sa peptidima i proteinima su pokazala da ovi kompleksi predstavljaju dobre katalitičke reagense za hidrolitičko raskidanje peptidnih veza u ovim molekulima. Ovi kompleksi se koordinuju za heteroatom u bočnom nizu aminokiseline L-metionina ili L- histidina i katalizuju raskidanje peptidne veze koja sadrži karboksilnu grupu neke od navedenih aminokiselina. Iako je ova oblast intenzivno izučavana u toku prethodnih nekoliko decenija, selektivnost i mehanizam raskidanja peptidne veze u peptidima koji sadrže L-metionin i L-histidin pomoću Pd(II) i Pt(II) kompleksa još uvek nisu potpuno objašnjeni. U cilju njihovog definisanja neophodno je detaljnije izučavati katalitički uticaj kompleksa Pd(II) i Pt(II) na reakcije hidrolize peptida koji sadrže L-metionin i L-histidin. U ovoj disertaciji prikazani su rezultati spektroskopskih ispitivanja hidrolitičkih reakcija peptida koji sadrže L-metionin i L-histidin u prisustvu različitih kompleksa Pd(II) i Pt(II). Studies of the palladium(II) and platinum(II) complexes have shown that they can be promising reagents for hydrolytic cleavage of peptides and proteins. These complexes bind to the heteroatom in the side chain of methionine or histidine and promote cleavage of the amide bond involving the carboxylic group of this anchoring amino acid. The consistent regioselectivity in the cleavage of histidine- and methionine-containing peptides promoted by palladium(II) and platinum(II) complexes and the mechanism of these hydrolytic reactions are not completely understood yet. A better knowledge of the coordination chemistry of histidine- and methionine-containing peptides with palladium(II)and platinum(II) complexes is necessary for understanding the regioselectivity of peptide and protein cleavage promoted by such complexes.

Sinteza i karakterizacija kompleksa zlata(III) sa nekim dipeptidima Glišić, Biljana Đ., 1985- zlato(III) kompleksi Nakon otkrića antitumorske aktivnosti cisplatine, posebna pažnja je posvećena ispitivanju kompleksa zlata(III) kao potencijalnih antitumorskih agenasa, zbog činjenice da su Au(III) i Pt(II) izoelektronski joni (d8 elektronska konfiguracija) i da formiraju kvadratno-planarne komplekse. Usled potencijalne primene kompleksa zlata(III) u lečenju tumora, u toku poslednjih nekoliko decenija,intenzivno su izučavane reakcije Au(III) jona sa biološki važnim ligandima, kao što su aminokiseline, peptidi i proteini. Mehanizam antitumorskog delovanja kompleksa zlata(III) još uvek nije u potpunosti razjašnjen i predstavlja predmet intenzivnih izučavanja. Ispitivanje reakcija kompleksa zlata(III) sa peptidima je od velikog značaja za definisanje mehanizma antitumorskog i toksičnog delovanja ovih kompleksa. After discovery of the anticancer properties of cisplatin, special attention was devoted to evaluation of gold(III) complexes as potential antitumor agents due to the fact that both Pt(II) and Au(III) ions possess the same d8 electronic configuration and preferentially form square-planar complexes. The possible involvement of gold(III)complexes in cancer treatment initiated an interest in the area of gold(III) interactions with different biologically important ligands such as amino acids, peptides and proteins. However, the mechanism of antitumor activity of gold(III) complexes is not yet completely understood and further investigation of this subject is required. A better knowledge of the gold(III) reactions with peptides contributes to the future development of gold(III) complexes as potential antitumor agents and also has importance in relation to the severe toxicity of gold-based drugs.

Sinteza, spektralna karakterizacija i mehanističke studije novih pirazolskih i pirazolonskih derivata Marković, Violeta, 1985- pirazolski derivati U okviru ove doktorske disertacije sintetizovana je serija N-[(1,3-difenil- pirazol-4-il)metil] α-amino-kiselina i N-[(3-ferocenil-1-fenilpirazol-4-il)- metil] α-amino-kiselina, uključujući i oba fenilalaninska enantiomera. U NMR studijama organometalnih derivata zapaženo je da dodatno cepanje orto- i meta- ferocenskih signala i njihov multiplicitet zavise od prirode α-amino-kiselinskog bočnog niza i ne mogu se pripisati samo hiralnosti α-amino-kiseline koja je vezana za pirazolov prsten. Efekat magnetne neekvivalentnosti oba orto-protona supstituisane ciklopentadienske jedinice naročito je izražen u jedinjenjima sa aromatičnim ili heteroaromatičnim prstenovima. U serinskom derivatu dobijenom iz 3-ferocenil-1-fenilpirazol-4-karbaldehida nije primećeno razdvajanje orto- ciklopentadienskih signala verovatno kao posledica formiranja vodonične veze između hidroksilne i karboksilne grupe, što ukazuje na postojanje neke druge konformacije sa umanjenim uticajem hidroksimetil-grupe na ferocenski sistem. Within this doctoral thesis a series of N-[(1,3-diphenylpyrazol-4-yl)methyl] α-amino acids and N-[(3-ferrocenyl-1-phenylpyrazol-4-yl)methyl] α-amino acids including both phenylalanine enantiomer derivatives were synthesized. NMR studies of the organometalic compounds revealed that additional splitting of the ortho and meta ferrocene signals as well as their multiplicities depend on nature of α-amino acid side chain and cannot be attributed to the chirality of pyrazole-linked α-amino acid alone. The effect of magnetic nonequivalence of both ortho protons of substituted cyclopentadiene (Cp) unit is particularly pronounced in compounds containing aromatic or heteroaromatic rings. In serine derivative of 3-ferrocenyl-1-phenylpyrazole-4-carboxaldehyde there is no appearance of splitting of ortho Cp signals probably as a consequence of hydrogen bond formation between hydroxyl and carboxylate group indicating a presence of an alternate conformation with reduced influence of CH2OH moiety on ferrocene scaffold.

Elektronsko i softversko rešenje kvadrofonske transmisione ultrazvučne defektoskopije u primeni na direktno laserski sinterovanim materijalima Ebersold, Zoran, 1960- kvadrofonska transmisiona ultrazvučna defektoskopska metoda, KTUD metoda Predmet ove doktorske disertacije predstavlja razvoj defektoskopa koji funkcioniše na principu nove ultrazvučne metode, nazvanoj kvadrofonska transmisiona ultrazvučna defektoskopska metoda (KTUD metoda), u primeni na direktno laserski sinterovanim materijalima (DLSM). Cilj rada je da pruži konkretan doprinos kontroli kvaliteta procesa proizvodnje DLSM proizvoda, predstavljanjem KTUD metode. Metoda omogućava jeftinu i efikasnu ultrazvučnu defektoskopiju elemenata proizvedenih DLSM postupkom. Ovim postupkom se izrađuju čvrsti, a ujedno lagani, porozni, šupljikavi elementi koji se primenjuju u tehnici orbitalnih satelita, tehnologiji najmodernijih motora i u avionskoj tehnici. Razvoj DLSM metode je pokušaj ispunjavanja zahteva za ekonomičnijom proizvodnjom malih serija mašinskih elemenata i sve kompleksnijih geometrija (kako spoljašnjih tako i unutrašnjih) metalnih elemenata. Trodimenzionalni element izgrađuje se na taj način što se dodaje jedan po jedan deo zapremine u obliku tankog sloja, čime nastaje porozan i šupljikav element, koji je čvrst i lak. Za razliku od indirektnog laserskog sinterovanja metala, DLSM se sastoji od samo jednog procesnog koraka što je prednost direktne metode jer se izbegava problematična procedura očvršćavanja u peći.

Sinteza i karakterizacija nekih kompleksa paladijma(II) i njihova potencijalna biološka aktivnost Synthesis and characterization of some palladium(ii) complexes and their potential biological activity Radić, Gordana P., 1980- R2-(S,S)-eddp ligandi, R2-(S,S)-eddv ligandi, S-alkil derivati tiosalicilne kiseline, H2-1,2-dpheddp·2HCl·H2O, paladijum(II) kompleksi, infracrvena i NMR spektroskopija, rendgenska strukturna analiza,antibakterijska aktivnost, antitumorska aktivnost. Otkriće antitumorskih osobina cis-diamindihloridoplatina(II)kompleksa, poznatijeg pod imenom cisplatina (cis-DDP) i sličnih kompleksa platine povećalo je interesovanje za dobijanje još efikasnijih kompleksa drugih metala i liganada. Među prvim kompleksima korišćenim u kliničkim ispitivanjima protiv tumora bili su paladijum(II) analozi cisplatine. Iako prvobitni rezultati nisu bili ohrabrujući, kompleksi paladijuma(II) su mnogo šire proučavani. Paladijum(II) kompleksi su skoro uvek pokazivali manju antitumorsku aktivnost u odnosu na odgovarajuće komplekse platine zbog njihove velike labilnosti. Da bi se ovi problemi prevazišli, mnoga istraživanja su bila usmerena ka upotrebi helatnih liganada koji bi umanjili reaktivnost paladijum(II) kompleksa. The discovery of anticancer activity of cis-diammindichloridoplatinum(II)complexes, better known as cisplatin (cis-DDP) and related platinum complexes has stimuled the interest for obtaining more efficient complexes of other metals and ligands. Some the first complexes used in clinical treatments against tumors were palladium(II)complexes as analogues of cisplatin. Although the first results were not encouraging,palladium complexes have been studied to longer extent. Palladium(II) complexes show less antitumor activity than corresponding platinum complexes due to their high instability. In order to overcome these problems, many studies have been directed toward the use of chelating ligands which would reduce the reactivity of palladium(II) complexes.

Ispitivanje kinetike i mehanizma reakcija kompleksa Pt(ii) i Pd(ii) sa biološki značajnim ligandima Bogojeski, Jovana B., 1980- Platina, Kompleksna jedinjenja oksaliplatina intezivno se koriste u hemoterapiji kao antitumorski reagensi. Poslednjih 40 godina veliki broj drugih platinskih jedinjenja sintetisano je sa ciljem da se postigne bolja aktivnost u odnosu na cisplatinu. Nedavno, počelo se sa sintezom neklasičnih platiniskih kompleksa, kao što su Pt(IV) kompleksi, koji mogu oralno da se upotrebljavaju, sterno zaštićeni Pt(II) kompleksi, polinuklearni Pt(II) kompleksi, kompleksi platine koji sadrže sumpor, itd. Mada tačan mehanizan kojim Pt(II) kompleksi ispoljavaju svoju antitumorsku aktivnost nije potpuno jasan, smatra se da svoju aktivnost kompleksi Pt(II) ispoljavaju interakcijom sa molekulom DNK, formirajući bifunkcionalni proizvod. Eksperimenti su pokazali da je vezivanje cisplatine za DNK kinetički a ne termodinamički kontrolisan proces. Međutim, upotreba platinskih antitumorskih jedinjenja ograničena je pojavom sporednih efekata i rezistentnosti. Takođe, mala rastvorljivost u vodenim rastvorima je dodatni efekat koji umanjuje kliničku upotrebu ovih jedinjenja. The chemistry of platinum complexes is important from the biological and medical point of view. Some Pt(II) complexes, viz. cisplatin, carboplatin and oxaplatin, are extensively used in chemotherapy as anticancer drugs. Over the last 40 years many other platinum drugs have been developed in an attempt to improve on isplatin. More recently, there have been efforts to direct the design of non-classical platinum complexes, such as orally active Pt(IV) complexes, sterically hindered Pt(II) complexes, polinuclear Pt(II) complexes, sulfur-containing platinum complexes, etc. Although the precise mechanism of a anti-tumour action of platinum drugs is not completely understood, the activity has been explained by the interactions between the complex and DNA primarily by forming bifunctional adducts. Experiments have demonstrated that cisplatin binding to DNA is kinetically rather than thermodynamically controlled. However, the application of platinum drugs has been greatly hampered by drug resistance and several side effects. Moreover, poor solubility in aqueous solution is also inconvenient in clinical use.

Modeliranje merne instalacije za nestandardna ispitivanja klipnih kompresora motornih vozila The test bench for non-standard testing of reciprocating compressors for motor vehicles Taranović, Dragan S., 1956- Merna instalacija, Klipni kompresor, Karakteristike kompresora Modeliranje test bench, reciprocating compressor, compressor characteristics, modeling Klipni kompresor kod motornih vozila je neophodna komponenta u sistemu proizvodnje komprimovanog vazduha koji se koristi u kočnom sistemu motornog vozila i za rad drugih uređaja. Stalno usavršavanje kompresora zahteva merenje karakteristika kompresora na odgovarajućoj, specifičnoj mernoj alaciji na kojoj mogu da se izmere standardni i nestandardni parametri compresora. Korišćenje neadekvatne merne instalacija, pored grešaka u merenjima, može da onemogući merenje dinamičkih promena parametara pa čak i da utiče na rad klipnih kompresora kao objekta ispitivanja i da uslovi formiranje pogrešnih zaključaka iz rezultata ispitivanja. Da bi se izbegla realizacija neadekvatne merne instalacije formiran je originalni matematički model merne instalacije i klipnog kompresora, koji predstavlja opterećenje merne instalacije. Simulacijama pomoću matematičkih modela ispitano je ponašanje merne instalacije i na osnovu rezultata simulacije i na osnovu prethodno definisanih standardnih i nestandardnih parametri kompresora projektovana je merna instalacija za ispitivanje klipnih kompresora motornih vozila. Na osnovu projekta je realizovana merna instalacija. Merenjima na kompresoru i samoj mernoj instalaciji dobijeni su rezultati koji su upoređeni sa rezultatima koji su dobijeni simulacijama na matematičkim modelima Reciprocating compressor in motor vehicles is a necessary component for the compressed air production system, used in motor vehicle’s braking system and for operation of other devices. Continuous compressor improvements demand the measurement of compressor characteristics at corresponding, specific test benches, where standard and non-standard compressor parameters may be measured. Application of inadequate test bench, in addition to measurement errors, may preclude the measurements of parameter’s dynamic variations and may even affect the operation of reciprocating compressors as test objects and induce the drawing of the wrong conclusions from the test results. In order to avoid the realization of inadequate test bench, an original mathematical model of the test bench and the reciprocating compressor as a test bench load was formed. By simulations using mathematical models, the test bench behaviour was investigated and, based on the simulation results and previously defined standard and non-standard compressor parameters, the test bench for testing of reciprocating compressors for motor vehicles was designed. The test bench was realized based on the project documentation. The results obtained by measurement on the compressor and on the test bench were compared to the results obtained by simulations using mathematical models. The test bench characteristics were verified separately from the reciprocating compressor characteristics, all by comparison with the simulation results. By comparison between the measurement and the simulation results, a good agreement of the results was established, thus verifying the test bench for non-standard testing of reciprocating compressors for motor vehicles Univerzitet u Kragujevcu Fakultet inženjerskih nauka Lukić, Jovanka Radonjić, Dragoljub Pešić, Radivoje Radulović, Jasna Petković, Snežana 2012 PhD thesis application/pdf http://eteze.kg.ac.rs/application/showtheses?thesesId=61 https://fedorakg.kg.ac.rs/fedora/get/o:122/bdef:Content/download https://plus.cobiss.net/cobiss/sr/sr/bib/518518677 sr Autorstvo-Nekomercijalno-Bez prerade 3.0 Srbija (CC BY-NC-ND 3.0)

Variational formulations and functional approximation algorithms in stochastic plasticity of materials Rosić, Bojana V., 1982- stohastička metoda Within the framework of innitesimal and large displacement elastoplasticity theory we consider a class of abstract stochastic variational inequalities of the second kind described by uncertain parameters. Particularly we focus on the rate-independent evolutionary problem with general hardening whose material characteristics are assumed to be distributed according to the maximum entropy law. By exhibiting the structure of the evolutionary equations in a convex setting we study the existence and uniqueness of the solution and carry the mathematical formulation over to the computationally more suitable mixed variational description. Within one time-backward Euler step the inequality reduces to a minimisation problem for smooth convex energy functional on discrete tensor product subspaces whose unique minimizer is obtained via a stochastic closest point projection algorithm based on white noise analysis". To this end we use a description in the language of nondissipative and dissipative operators and introduce the stochastic Galerkin method into the computational process in fully intrusive and non-intrusive variant. The former method represents the direct, purely algebraic way of computing the response in each iteration of Newton-like methods. As the solution is given in a form of polynomial chaos expansion, i.e. an explicit functional relationship between the independent random variables, the subsequent evaluations of its functionals (the mean, variance, or probabilities of exceedence) are shown to be very cheap, but with limited accuracy. Furthermore, the method is contrasted to the less-ecient but more accurate non-intrusive variant which evaluates the residuum in each iteration via highdimensional integration rules based on random or deterministic sampling - Monte Carlo and related techniques. In addition to these, we also present the stochastic collocation method via sparse grid techniques. Finally the methods are validated on a series of test examples in plain strain conditions whose reference solution is computed via direct integration methods. U okviru teorije malih i velikih plasticnih deformacija razmatrana je klasa apstraktnih stohastičkih varijacionih nejednakosti opisanih slučajnim promenljivama. Poseban fokus je stavljen na asocijativni evolucioni problem sa generalnim ojačanjem čije materijalne karakteristike imaju distribuciju odredenu zakonom maksimalne entropije. Proučavajući strukturu evolucionih jednačina uz pomoć konveksne teorije uslovi za postojanje i jedinstvenost rešenja su analizirani uz dodatnu matematičku reformulaciju problema u numerički prikladan mešoviti varijacioni opis. Dobijena nejednakost se nakon implicitne diskretizacije svodi na minimizaciju konveksnog funkcionala denisanog u tenzorskom prostoru dobijenom kao proizvod determinističkog i stohastičkog podprostora. Rešenje tako postavljenog problema se može dobiti novouvedenom stohastiškom metodom projekcije najbliže tačke uz pomoć teorije analize belog šuma. Pomenuta metoda se sastoji od dva koraka: elastičnog i plastičnog, koji zajedno čine stohastičku Galerkinovu metodu, ovde formulisanu na dva načina: direktan (intruzivan) i posredan (neintruzivan). Prva varijanta predstavlja direktan, algebarski način dobijanja rešenja u svakoj iteraciji Njutnove metode. Zahvaljujući polinomnoj formi rešenja sve predstojeće evaluacije njegovih funkcionala kao što su srednja vrednost, varijansa itd. postaju računski jako efikasne, ali ograničene tačnosti. U cilju unapredenja tačnosti Galekinova methoda je implementirana i u svojoj manje efikasnoj neintruzivnoj varijanti, koja računa rezidual u svakoj Njutnovoj iteraciji numeričkom (determinističkom ili stohastičkom) integracijom. Obe varijante Galerkinovih metoda su uporedene sa metodom stohastičke kolokacije zasnovane na sparse grid pravilu.

Ocene grešaka kvadraturnih formula Gausovog tipa za analitičke funkcije Pejčev, Aleksandar, 1985- numerička integracija, Gausove kvadraturne formule The field of research in this dissertation is concerned with numerical integration,i.e. with the derivation of error bounds for Gauss-type quadratures and their generalizations when we use them to approximate integrals of functions which are analytic inside an elliptical contour Eρ with foci at ∓1 and sum of semi-axes ρ > 1. Special attention is given to Gauss-type quadratures with the special kind of weight functions - weight functions of Bernstein–Szeg˝o type. Three kinds of error bounds are considered in the dissertation, which means analysis of kernels of quadratures, i.e. determination of the location of the extremal point on Eρ at which the modulus of the kernels attains its maximum, calculation of the contour integral of the modulus of the kernel, and, also, series expansion of the kernel. Beyond standard, corresponding quadratures for calculation of Fourier expansion coefficients of an analytic function are also analysed in this dissertation.

Numeričko modeliranje difuzije u kompozitnim medijumima Milošević, Miljan, 1984- difuzija, numeričko modeliranje Највећи део истраживања у прошлости из области дифузиje је обављен на нивоу макро-скале где фундаментални закони, као што су Фиков и Дарсијев закон, описују кретање одговарајуће супстанце кроз произвољни медијум. Међутим, на кретање супстанце кроз поре сложених микроструктура утичу не само граничне површине солида услед којих се мењају путање супстанце, већ и хемијска интеракција између супстанце и површина солида. Ова интеракција постаје веома битна и може знатно утицати на просечну брзину дифузионог процеса у нано-ограниченом простору. Стога, Фиков закон не може довољно прецизно да опише дифузиони процес па се површинска интеракција, која се јавља на молекулском нивоу, мора узети у обзир. Један од начина да се одреде карактеристике дифузије са утицајем површина је молекуларна динамика (МД), помоћу које је могуће одредити интеракцију између супстанце и зида на атомском и молекулском нивоу. Међутим, због великог броја интеракција које треба да буду узете у обзир, МД постаje непрактична чак и за веома мале домене (реда милиметра). Осим метода молекуларне динамике, развијен је велики број метода механике континума, као што је метод коначних елемената, у циљу изучавања порозних система. Код ових континуалних метода се узимају у обзир термодинамичке карактеристике, али се ипак физика утицаја површина оставља по страни. particles, which all together affect diffusion process. Despite the increasing focus on nanofluidics in many of these applications, the laws governing molecular transport through nanoscale fluidic channels and porous media have not been fully understood. As the size of the channels and pores is reduced to the molecule size, classical continuum theories fail to predict even the basic characteristics of fluid transport.

Distribucija, filogenija, ekologija i konzervacija rakova iz familije Astacidae na području Crne Gore Distribution, phylogeny, ecology and conservation of crayfish of the family Astacidae in Montenegro Rajković, Milka L., 1973- Rečni rak, ekologija Do danas je u svijetu opisano oko 600 vrsta slatkovodnih (Decapodnih) rakova iz podreda Astacidae. Na području Evrope danas živi pet vrsta autohtonih slatkovodnih rakova iz porodice Astacidae: Astacus astacus, Astacus leptidactilus, Astacus pachypus, Austropotamobius pallipes, i Austropotamobius torrentium. Pored autohtonih, danas žive i alohtone vrste. Najčešće su to američke vrste Pacifastacus leniusculus (Dana, 1852) takođe iz porodice Astacidae. Sve tri vrste (A. astacus, A. pallipes i A. torrentium) zaštićene su i na nivou Evrope: uvrštene su na IUCN ovu crvenu listu ugroženih vrsta (IUCN - International Union for Conservation of Nature) takođe su uvrštene i u Apendiks br. III Bernske konvencije po kojem je njihovo iskorišćavanje pod strogom kontrolom i nadzorom svake države (Taylor, 2002), a vrste A. torrentium, i A. pallipes su i u Direktivi o staništima Evropske unije. Cilj ove doktorske disertacije bio je analizirati populacije različitih vrsta slatkovodnih (Decapodnih) rakova sa prostora Crne Gore kako bi se dobili podaci o njihovoj distribuciji, ekologiji, kao i da se odrede filogenetski i evolucijski odnosi jedinki vrsta A. torrentium, A. pallipes i A. astacus uzorkovanih sa prostora Hrvatske, Srbije i Crne Gore kao i njihova procjena rizika izumiranja i prioriteti konzervacije biodiverziteta akvatičnih ekosistema. Up to date, about 600 species of freshwater (Decapods) crayfish from Astacida suborders was described in the world. Today, five species of freshwater crayfish from the family Astacidae (Astacus astacus, Astacus leptidactilus, Astacus pachypus, Austropotamobius pallipes and Austropotamobius torrentium) lives in Europe. Besides to autochthonous, now there are allochthonous species living there. They are mainly American species Pacifastacus leniusculus (Dana, 1852) also from the family Astacidae. All three species (A. astacus, A. pallipes and A. torrentium) are protected at European level: listed on IUCN Red List of threatened species (IUCN - International Union for Conservation of Nature) and they are also having been included in Appendix no. III of the Bern Convention by which their exploitation is under strict control and supervision of each state (Taylor, 2002), and type A. torrentium, and A. pallipes are in the Habitats Directive of the European Union. The goal of this dissertation was to analyze the populations of different species of freshwater (Decapods) crayfish from Montenegro in order to obtain information on their distribution, ecology, and to determine the phylogenetic and evolutionary relationships between individuals of species A. torrentium, A. pallipes and A. astacus sampled from Croatia, Serbia and Montenegro as well as their assessment of extinction risk and conservation priorities for biodiversity in aquatic ecosystems. The analysis included physically-chemical parameters of waters where was registered the presence of freshwater (Decapods) crayfish. For each caught crayfish 23 morphometric feature were measured and described by standard descriptive statistics (medium value, min-max value, standard deviation, and coefficient of variation). Same morphometric characteristics have been measured for the species A.astacus from the lake Buser-Serbia and they have also been described by the standard descriptive statistics. The data were then normalized on the way that their value was divided by the corresponding postorbital length (POL = HEL + ARL) and the results related to the morphometric characteristics were taken into account only the normalized input values. For normally distributed data we used the parametric T-test to compare differences of morphometric characters for males and females, and for a small number of samples we have been used Mann-Whitney U test. Variance analysis (ANOVA) was used to establish whether there are statistically important differences between populations of the same species or different species. Considering that there were differences, we worked discriminate analysis (DA).

Sinteza regulatora fiksnog reda za sisteme upravljanja sa dugačkim hidrauličnim vodovima Synthesis of fixed-order controllers for control systems with long transmission lines Dubonjić, Ljubiša M., 1971- Hidraulični vodovi sitemi upravljanja Doktorska disertacija pod naslovom ―Sinteza regulatora fiksnog reda za sisteme upravljanja sa dugačkim hidrauličkim vodovima‖ odnosi se na problem projektovanja regulatora fiksnog reda kada treba upravljati hidrauličkim izvršnim organima (pogonima) sa dugačkim vodovima, koji su opisani matematičkim modelima visokog reda. Obrađena je kroz sedam poglavlja. Prvo poglavlje ukazuje na potrebu i značaj istraživanja sistema sa zapreminskim upravljanjem zbog niza prednosti u odnosu na sisteme sa prigušnim upravljanjem, a posebno sa aspekta energetske efikasnosti. Pošto su ovi sistemi opisani matematičkim modelima visokog reda, ukazano je na neophodnost pronalaženja metodologije za projektovanje regulatora fiksne strukture i niskog reda za upravljanje ovim sistemima, a u cilju poboljšanja kvaliteta rada hidro i hidroelektričnih izvršnih organa sa dugačkim hidrauličkim vodovima. U drugom poglavlju je dat pregled istraživačkih rezultata iz oblasti hidro i hidroelektričnih sistema upravljanja sa dugačkim hidrauličkim vodovima, kao i rezultata iz oblasti teorije upravljanja. Treće poglavlje prikazuje, kroz sveobuhvatni metodološki prilaz, oblike matematičkih modela stujanja radnog fluida u dugačkim upravljačkim hidrauličkim vodovima, od najjednostavnijih do najsloženijih. Modeli su iskazani kroz matrične zavisnosti i sprege hiperboličkih funkcija i izvršen je njihov tabelarno sređen prikaz. Uz realne vrednosti parametara prikazane su frekventne karakteristike usvojenih modela, kao i njihova analiza u frekventnom domenu. The doctoral dissertation ―Synthesis of Fixed-Order Controllers for Control Systems with Long Transmission Lines‖ refers to the problem of fixed-order controller design when hydraulic executive bodies (drives) with long transmission lines, which are described by mathematical models of high order, should be controlled. It consists of seven chapters. Chapter I points out the need for and significance of research on systems with displacement control because of a lot of advantages in relation to the systems with damping control, especially from the aspect of energy efficiency. As these systems are described by mathematical models of high order, the dissertation indicates the necessity of finding a methodology for design of controllers with fixed structure and low order for control of these systems for the purpose of improving the quality of operation of hydraulic and electro-hydraulic executive bodies with long transmission lines. Chapter II provides an overview of research results in the field of hydraulic and electro-hydraulic control systems with long transmission lines as well as results in the field of control theory Chapter III, through a comprehensive methodological approach, presents forms of mathematical model of flow of working fluid in long transmission lines, from the simplest to the most complex ones. The models are shown through matrix dependences and combination of hyperbolic functions and they are presented in tables. Frequent characteristics of the adopted models as well as their analysis in the frequency domain are presented with real values of parameters. Chapter IV develops the methodology of design of P controllers in the system of pump-controlled motor with a long transmission line. The methodology of P controller design was carried out by the root locus of the closed loop where the performances were also included through the specification of relative stability of the system, which implies an a priori given location of poles of transmission function of the closed loop in a complex plane determined on the basis of known requirements. It was shown that the designed controller gave good performances even during variation of the parameters in the system components (for instance: the viscosity coefficient and the module of compressibility which considerably change with the change of temperature and pressure). By using the possibilities offered by computers and software, a simple graphical method for design of the P controller, which often satisfies practical needs, was developed.

Mikrobiološki aspekti primene informacionih sistema u monitoringu akumulacija i jezera Radojević, Ivana D. Vode, zaštita voda; Gružanko jezero bakterijske zajednice Procena povezanosti uticaja koji neki fizički, hemijski ili biološki parametri imaju na određenu bakterijsku zajednicu ili obrnuto, je kako fundamentalna u boljem razumevanju samih bakterijskih zajednica, tako i praktična u praćenju, predviđanju i unapređenju stanja kvaliteta voda. Bakterijske zajednice imaju veliki značaj u funkcionisanju akvatičnih ekosistema i određivanju njihovog kvaliteta. Na osnovu te činjenice, postojećih podataka iz ranijih naučnih i standardnih hidrobioloških istraživanja, odabrane su tri akumulacije u Srbiji koje se razlikuju po morfometrijskim osobinama, trofičkom statusu i dominantnoj zajednici bakterija. Na njima su primenjeni novi, savremeni alati informacionih tehnologija i korišćene metode DM, nove za ovu oblast istraživanja, sa ciljem da se utvrde: - stepen zavisnosti i veličina uticaja bakterijskih zajednica međusobno; - stepen zavisnosti i veličina uticaja relevantnih fizičkih, hemijskih i bioloških parametara na stanje i dinamiku različitih bakterijskih zajednica i vrsta; - predviđanje stanja na osnovu dobijenih rezultata; - najefikasnije metode za racionalizaciju i povećanje efikasnosti limnoloških istraživanja u Srbiji, uspostavi adekvatan monitoring i doprinese održivom upravljanju akumulacijama i jezerima Univerzitet u Kragujevcu Prirodno-matematički fakultet Čomić, Ljiljana, 1954- Kungulovski, Džoko.

Grafovi čija je najmanja karakteristična vrednost minimalna u nekim klasama grafova Aleksić, Tatjana, 1982- Teorija grafova 519.1 Spectral graph theory is an important interdisciplinary field of science and mathematics in which methods of linear algebra are used to solve problems in graph theory. It has numerous applications for modelling problems in chemistry, computers science, medicine, economy, and physics, to name just a few. By representing a graph as an adjacency matrix, matrix theory can be applied to graph theory. Features of the graph can be investigated using the eigenvalues and the eigenvectors of the adjacency matrix, and these give us information about the graph’s structure. The eigenvalues of a graph G can be ordered decreasingly, where the first is denoted by (G) and is called the index of the graph and the least eigenvalue is denoted by (G). A graph’s spread s(G) is defined as the difference between the greatest and the least eigenvalue of the graph’s adjacency matrix, i.e. s(G) = (G) − (G). The principal topic of this doctoral thesis is the least eigenvalue of a graph. The structure of a graph G that has the minimum least eigenvalue within a certain class of graphs is determined. This graph is referred to as an extremal graph.

U slučaju brahistohronog kretanja materijalne tačke razmatran je slučaj kada se materijalna tačka kreće u vertikalnoj ravni u homogenom gravitacionom polju duž veze u obliku hrapave linije sa Kulonovim trenjem, pri čemu je početna brzina tačke različita od nule. Analiza brahistohronog kretanja tačke je sprovedena za slučaj kada se veza tretira kao zadržavajuća i za slučaj kada se veza tretira kao nezadržavajuća. Izvršena je generalizacija rezultata iz literature, koji su tretirali ovu problematiku primenim varijacionog računa u slučaju kada je početna brzina tačke jednaka nuli, uvođenjem pretpostavke o znaku normalne reakcije veze kao dodatnog ograničenja u varijacionoj formulaciji problema. The brachistochrone motion of the particle and the rigid multibody systems in the presence of Coulomb friction was analyzed by the application of variational calculus. In case of the brachistochrone motion of the particle, the case when the particle moves in the vertical plane in the homogeneous gravitational field along the coustraint in the form of a rough curve with Coulomb friction was considered, where the initial velocity of the particle was diff'erent fiom zero. The analysis of the brachistocluone ntotion of the particle was performed for the case when the constraint is treated as bilateral and for the case when the constraint is treated as unilateral. By introducing the assumption regarding the sign of the normal reaction of the constraint as an additional constraint in the variational formula of the problem, the results from the references treating these problems by variational calculus with the assumption that the initial velocity of the parlicle is equal to zero were generahzed. The equations of the brachistochroue were obtained in their parameter form, where the slope angle of the tangent on the brachistochrone curve was taken as the parameter. It was shown that the brachistochrone in the general case is a two-segment curve w'ith the initial line segment representing a free-fall parabola in nonresistant medium. The application of obtained results in the problems of optimization in a plant for transportation of granular nraterial was presented. In this technical object, the problem of minimization of losses of rnechanical energy due to the action of Coulomb friction during transporlation of granular material was analytically solved. In the brachistochrone motion of a constrained system of rigid bodies, the case when a certain number of unilateral constraints treated as real constraints with Coulomb friction are fbLrnd among the constraints imposed on the system. A general approach to solution by the application of the ntethodology used in the problem of brachistochrone motion of the particle was given. Within this chapter of the dissertation, a special type of the mechanical system with two degrees of freedom on which the analogy of solving the brachistocluone problem of this system with the brachistochrone problem of the particle considered in the first two chapters of the dissertation was analyzed. The results were obtained in the form which is suitable for illustration on specific technical objects and further numerical analysis. The application of differential evolution, as the optimization method, in solving systems of nonlinear algebraic equations was mentioned.

Stavovi o nepokretnoj tački na prostorima sa nedeterminističkom metrikom Nikolić, Rale, 1976- Teorija nepokretne tačke 51 From Freschet’s definition of metric space in the early twentieth century, the various generalizations of metric spaces such as Menger spaces, fuzzy metric spaces, intuitionistic fuzzy metric spaces, L-fuzzy metric spaces and others, were obtained. On the other hand, the fundamental theorem in the theory of fixed points in metric spaces represents Banach contractive Principle. This theorem, which for some special cases has already been considered by a Liouville, Picard and Goursat, in the past eight decades till today, has found many important applications and has been generalized in many directions. One of them is the introduction of nonlinear contractive condition by Rakotch in 1962, and then by Boyd and Wong in 1969. The field of research in this dissertation belongs to the nonlinear functional analysis, and partly to the topology and applied mathematics. Since the basic structures on which we conduct our research are the spaces with nondeterministic distances, the obtained results have applications in modern scientific research in physics. In this dissertation,the nonlinear contractive condition which is associated with different forms of the boundness of sets in the spaces with nondeterministic distances, will be discussed. In addition, we will be discussing the existence and uniqueness of fixed and common fixed points, under conditions of weak commutativity and compatibility for different types of mappings. The hypothesis of the proceeding is that with qualitatively characterization for the domain of mapping, we can relax the conditions of nonlinear contraction and thereby obtain information about the existence or absence of fixed points for this mapping. A special place in this dissertation takes convexity and topological characterization of completeness and compactness of the spaces with nondeterministic distances. These results are associated with the existence of fixed and common fixed points for non-expansive mappings, with nonlinear contractive condition. The main question is how the convex structure and the previously mentioned results, can be transferred to the spaces with nondeterministic distances.

Epilepsija u srpskim srednjevekovnim zemljama EPILEPSY IN SERBIAN MEDIEVAL LANDS Ilić-Tasić, Slobodanka, 1954- Epilepsija srpske zemlje U našoj i svestskoj istoriografiji objavljen je veliki broj studija i naučnih radova u kojima je proučavana epilepsija i njeni vidovi lečenja u različitim vremenskim periodima. Neke od tih studija prilaze epilepsiji sa istorijske tačke gledišta i pokušavaju da rasvetle različite metode tradicionalne narodne medicine. Brojnija istraživanja pripadaju savremenoj naučnoj medicini (ispitivanje farmakološkog dejstva aktivnih principa lekovitog bilja, kao i antikonvulzivnog dejstva pojedinih lekovitih biljaka na životinjskim modelima i kliničkim studijama). Manji broj studija je posvećen lečenju epilepsije u srednjovekovnoj medicini. Ovu studiju možemo svrstati u studije medicine i dodirnih grana jer se radi o studiji iz istorije medicine koja je urađena multidisciplinarnim pristupom sa stanovišta etnologije, farmacije (fitoterapije), religije, filozofije, književnosti i drugih. Cilj ove studije je izvođenje komparativne analize epilepsije i metoda njenog lečenja u srpskim srednjovekovnim zemljama u prošlosti i u savremenoj medicini. Metod rada će obuhvatiti komparativnu analzu epilepsije u srpskim zemljama u srednjem veku i drugim evropskim zemljama toga doba na osnovu podataka dobijenih izučavanjem srednjovekovnih spisa (hagiografija, biografija, kodeksa), zakonskih spisa koji se odnose na epilepsiju i dokumenta o uređenju srpskih srednjovekovnih manastirskih bolnica. Proučavanje obuhvata srpske zemlje u periodu srednjeg veka, od IX do sredine XV veka. A number of studies and scientific papers in which the epilepsy and its treatment in different historical periods were studied are published both in our and in the world historiography. The epilepsy is approached by some of these studies from a historical point of view with attempt to shed light on the different methods of the traditional folk medicine. Numerous studies belong to the modern scientific medicine (research of the effects of the pharmacologically active principles of medicinal herbs; anticonvulsant effects of some medicinal plants in animal models and in clinical studies). A smaller number of studies were devoted to the treatment of epilepsy in medieval medicine. This study can be classified as the study in the field of the history of medicine and the common branches. This study is characterized with ultidisciplinary approach from the standpoint of ethnology, pharmacology, phytotherapy, religion, philosophy, literature and others. The aim of this study is to perform a comparative analysis of epilepsy and methods for its treatment between them in Serbian medieval countries and in contemporary medicine.

Izbor rekonstruktivnih zahvata u hirurškoj terapiji karcinoma dojke Choice of reconstructive procedures in the surgical treatment of breast cancer Azanjac, Goran, 1964- karcinom dojke, mastektomija,komplikacije, rekonstrukcija, neposredna,odložena mastektomija Karcinom dojke predstavlja heterogenu bolest sa različitim morfološkim i molekularnim karakteristikama, biološkim ponašanjem i reagovanjem na terapiju, predstavljajući najrasprostranjeniji maligni tumor kod žena. U savremenoj hirurgiji, rekonstrukcija dojke predstavlja integralni aspekt u lečenju karcinoma, čime se bezbedno i efikasno, u bilo koje vreme, kao jednostepeni ili dvofazni postupak, restauracijom dojke uspostavlja telesni integritet i smanjuje postoperativni komorbiditet. PACIJENTI I METOD. Istraživanje predstavlja kliničku studiju prospektivno-retrospektivnog tipa, kojom su obuhvaćene 124 pacijentkinje, u periodu od januara 2005. do januara 2010.godine. Pacijentkinje su svrstane u kontrolnu grupu (40) kod kojih je izvedena izolovana mastektomija i eksperimentalnu (84) u kojoj su pacijentkinje sa izvedenom mastektomijom i rekonstrukcijom dojke, prosečne starosti 53,5god. za kontrolnu i 43god. za eksperimentalnu grupu. REZULTATI. Naši rezultati pokazuju da nema značajne razlike u učestalosti komplikacija kod izolovanih mastektomija i mestektomija sa rekonstrukcijom, kao i da je nivo komplikacija kod neposrednih rekonstrukcija niži u odnosu na odložene.Stopa učestalosti komplikacija kod neposrednih rekonstrukcija implantatima iznosi 26,92% od čega su u 19,23% identifikovane kao minor a u 7,69% kao major komplikacije. Pojavu hematoma beležimo u 3,85%, duboku infekciju u 4,76%, serom u 19,23%. Kapsularnu kontrakturu beležimo u 3,85%.Utvrdili smo postojanje značajne veze između veličine tumora i stadijuma tumorske bolesti i učestalosti komplikacija.Takođe smo našli postojanje pozitivne korelacije između indeksa telesne mase i pojave komplikacija. Naši rezultati pokazuju i postojanje značajne veze između hroničnih oboljenja, hemio i zračne terapije i pušenja sa pojavom komplikacija.Sa prosečnom cenom koštanja od 83.544,50 din. neposredna rekonstrukcija implantatima predstavnja ekonomski najprihvatljiviju opciju u rekonstrukciji dojke.Tokom istraživanja, posebno su nas interesovali stav i saznanja ispitanica o telesnom izgledu, psihološkom statusu, očuvanoj seksualnosti i samopoštovanju. Anketa je formirana samo za ovu priliku, nije univerzalna i visoko specifična. Predstavlja autorski koncept formiran na osnovu sličnih istraživanja sprovedenih u svetu i na osnovu preporuka Svetske zdravstvene organizacije (World Health Organization) o posmatranju fizičkog, emocionalnog i socijalnog statusa kod žena operisanih od karcinoma dojke. Mi smo pri konstrukciji pitanja kao polaznu osnovu imali strukturu i dizajn HRQoL, Health Survey SF-36, Body Image Questionnaire European Organization for Research and Treatment of Cancer (E.O.R.T.C.Quality of life).Analizirali smo srednje vrednosti skorova, na skali od 0 do 10. Najviše vrednosti skorova (9) vezane za pitanja o telesnom izgledu, samopuzdanju, seksualnosti, ženstvenosti i samopoštovanju, imamo kod neposrednih rekonstrukcija, kod kojih je zbeležen i najniži nivo psihičkih tegoba (9,09%).ZAKLjUČAK.Ustanovili smo da neposredna rekonstrukcija implantatima predstavlja metodu izbora u lečenju operabilnih karcinoma dojke. Kod ovih pacijentkinja je sveukupno zadovoljstvo najizraženije,sa najoptimalnijim 137 psiho-socijalnim efektima, zadovoljavajućim kvalitetom seksualnog života i opšte životnim aktivnostima.Neposredne rekonstrukcije implantatima,predstavljaju bezbednu opciju sa niskom stopom postoperativnih komplikacija i ekonomski su najprihvatljivije. Breast cancer is a heterogeneous disease with different morphological and molecular characteristics, biological behavior and response to therapy, representing the most widespread malignant tumor in women. In modern surgery, breast reconstruction is an integral aspect in the treatment of cancer, which is safe and effective, at any time, as a singlestage or two-stage procedure, restoration of established breast physical integrity and reduces postoperative comorbidity. PATIENTS AND METHODS. The study is a prospectiveretrospective clinical study, which included 124 patients, from January 2005. by January 2010. Patients were divided into a control group (40) in which the mastectomy was performed isolated and experimental (84) in which patients were performed with the mastectomy and reconstruction, mean age 53.5 years. for control and 43 years for the experimental group. RESULTS. Our results show no significant differences in complication rates for isolated mastectomy with reconstruction and mastectomy, and that the level of complication in the immediate reconstruction of lower than delayed. Incidence of complications in the immediate implant reconstruction is 26.92%, of which 19,23% ware identified as minor and 7.69% as major complications. Hematoma recorded at 3.85%, deep infection of 4.76%, 19.23% in seroma. Capsular contracture recorded at 3.85%. Existence we found significant associations between tumor size and stage of disease and tumor incidence complications. We found a positive correlation between body mass index and the occurrence of complications. Our results show the existence of a significant link between chronic disease, chemotherapy and radiotherapy and smoking with the appearance of complications. With the average cost price of 83544.50 din immediate implant reconstruction is the most economically advantageous option for breast reconstruction. During the research, we are particularly interested in attitude and knowledge about the physical appearance of women, psychological status, sexuality and self-preserved. The survey was created for this purpose, it is not universal and highly specific. Author presents a concept formed the basis of similar studies conducted in the world and based on the recommendations of the World Health Organization (World Health Organization) on the observation of physical, emotional, and social status of women operated on for breast cancer. We are in the construction of questions as a starting point had the structure and design of HRQoL, Health Survey, SF-36, Body Image Questionnaire European Organization for Research and Treatment of Cancer (EORTC Quality of life). Analysis included the mean scores on a scale of 0 to 10. The highest mean scores (9) related to questions about body image, self-esteem, sexuality, femininity and selfesteem, we have the immediate reconstruction, in which the lowest level is and mental illnesses (9.09%).CONCLUSION. We found that immediate implant reconstruction the method of choice in the treatment of operable breast cancer. In these patients, the overall satisfaction with the most pronounced, with the most optimal psycho-social effects, satisfactory quality of sexual life and general life activities. Immediate reconstruction with implants a safe option with a low rate of postoperative complications, and economic considerations are the most appropriate.

Uticaj stanja sluha na depresiju, anksioznost i kvalitet života pacijenata sa tinitusom Dragutinović, Ninoslava, 1962- oštećenje sluha, tinitus, depresija, anksioznost, kvalitet života 616 Uvod. Čulo sluha je veoma značajno za omogućavanje govora i ostvarivanje komunikacije a poremećaj njegove funkcije menja čovekovu ličnost, ograničava ispoljavanje sposobnosti i značajno utiče na psihičke, emocionalne i socijalne aspekte života. Poremećaj slušne funkcije predstavlja veliki problem zbog onesposobljenosti,komorbiditeta sa mentalnim poremećajima (depresija i anksioznost) i značajnog smanjenja kvaliteta života, kao značajanog faktora u sagledavanju stanja zdravlja. Stepen oštećenja sluha (prag sluha) nije od suštinskog značaja kao individualna percepcija oštećenja zbog čega je neophodno utvrditi audiološke parametre u funkciji komunikacije, socijalnih kontakata i mentalnog zdravlja. Primena testova za samoprocenu slušne i tinitus onesposobljenosti, psihološko-psihijatrijskih skala za procenu prisustva i izraženosti depresivnih i anksioznih simptoma, omogućuju pravilno sagledavanje relativnih prednosti i ograničenja za određene opcije terapijskih tretmana ili slušne rehabilitacije, prevenciju i rano sagledavanje mentalnih poremećaja. Cilj. Cilj istraživanja je bio da se ispita uticaj oštećenja sluha na pojavu depresije, anksioznosti i kvalitet života kod ispitanika sa tinitusom. Metod. Istraživanje je po tipu kliničke, prospektivne studije preseka. U trajanju od šest meseci istraženo je prisustvo mentalnih poremećaja kod ispitanika sa i bez oštećenja sluha i tinitusom. Istraživanjem je obuhvaćeno 92 ispitanika oba pola, starosti od 40 – 65 godina, sa normalnim i kohlearnim, senzorineuralnim oštećenjem sluha i tinitusom u trajanju od 3 meseca do 5 godina. Vodeći parametar su bili rezultati upitnika za samoprocenu težine onesposobljenosti zbog oštećenja sluha i tinitusa i njihova korelacija sa skalama za procenu prisutva i težine depresije, anksioznosti i kvaliteta života. Hearing sense is very important for enabling speech and establishing communication. Disabling it’s function alters the ones personality, limits expression of it’s capabilities and significantly affects it’s psychological, emotional and social aspect of it’s life. Hearing handicap is a big problem because of disability, comorbidity with mental disorders (depression and anxiety ) and significant decrease of quality of life, as important factor in overview of health state. The level of hearing handicap (hearing threshold) is not of crucial relevance as individual perception of damage, which is why it is necessary to determine audiology parameters in function of communication, social contacts and mental health. Usage of tests for self evaluate of hearing and tinnitus disability, psychological-psychiatric scales for evaluating presence and magnitude depressive and anxiety symptoms, enables adequate overviewing of relevant advantages limitations for certain options therapeutic treatments or hearing rehabilitation, prevention and in time observation of mental disorders. Goal. Goal of research was to examine influence of hearing disability on developing depression, anxiety and life quality of respondents with tinnitus. Method. Research Is by the type of clinical, prospective cross-sectional study.

Nalaz koštane modrice na magnetnoj rezonanci, kod akutne traume kolena, u STIR u poređenju sa T1 sekvencom kod povreda prednje ukrštene veze i meniskusa Finding of bone bruise on magnetic resonance imaging in acute knee trauma in STIR comparing to T1 sequence in anterior cruciate ligament and menisci lesions Jelić, Đorđe, 1967- Koleno, koštana modrica 616 Magnetna rezonanca (MR) je metoda izbora za dijagnostikovanje povreda unutrašnjih mekotkivnih struktura, kao što su meniskusi, ukrštene veze i zglobna hrskavica. Osim toga, MR je jedina dijagnostička metoda koja prikazuje i posttraumatske promene koštane srži, zvane koštane modrice (KM). Preciznom analizom prisustva i lokacije KM se može razjasniti mehanizam traume kolena, što omogućava bolji uvid u očekivane, udružene, povrede unutrašnjih struktura kolena. Cilj : Cilj disertacije je da se utvrdi razlika u stepenu senzitivnosti STIR u odnosu na T1 sekvencu u detekciji koštanih modrica. Potom da se analizom stepena udruženosti KM i lezija prednjeg ukrštenog ligamenta(ACL) i meniskusa utvrdi značaj KM kao pomoćnog znaka za dijagnostikovanje povreda prednjeg ukrštenog ligamenta i meniskusa. Utvrditi učestalost KM i lezija ACL po sportovima. Introduction: Magnetic resonance (MR) imaging is a method of choice in diagnosing internal soft tissue injuries of the knee, such as menisci, cruciate ligaments and joint cartilage. It is, as well, the only method for detecting posttraumatic changes in bone marrow, so called bone bruises. Precise analysis of presence and location of bone bruise can explain the pattern of the knee trauma which enables better insight into internal knee lesions. Aim : The aim of the dissertation is to determine the difference in sensitivity of STIR sequence comparing to T1 on MR imaging for detecting bone bruises. The second aim is to determine the importance of bone bruise as the additional sign for detecting postinjury lesions of anterior cruciate ligament (ACL) and menisci by determing their association. The additional aim is to determine the association of bone bruise frequency with injuries of ACL regarding the sport. Material and methods: A representative review of 100 MR examinations for the acute knee trauma in different sports was conducted. All the patients were examined within one month of trauma. All MR examinations were performed by using MRP 7000 0.3 T Hitachi MR unit. The standard imaging protocol with SE T1 sagital, FS T2 sagital,coronal, axial and STIR sequence was used. The presence and site of bone bruises were analyzed as well as the difference in bone bruise frequency on STIR and T1 sequence and the level of sensitivity of these sequencies in detecting bone bruises. The frequency of soft tissue lesions of the knee especially ACl and menisci and their association with bone bruises was also analyzed. We have also analyzed the frequency of bone bruises in different sports which led to the knee trauma.

Upoređenje odnosa troškova i efikasnosti fidaksomicina i vankomicina u lečenju kolitisa izazvanog sa Clostridium difficile pomoću Markovljevog modela Comparison of the cost-effectiveness fidaxomicin and vancomycin in the treatment of colitis caused by Clostridium difficile by using a Markov model Marković, Veroljub, 1952- fidaksomicin, vankomicin, Clostridium difficile, kolitis, odnos troškova i efikasnosti fidaksomicin UVOD:Kolitis izazvan toksinom bakterije Clostridium difficile nastaje posle upotrebe antibiotika i predstavlja teško oboljenje sa visokim morbiditetom i mortalitetom. Novi makrociklični antibiotik fidaksomicin je 8 puta aktivniji in vitro od vankomicina protiv Clostridium-a difficile, ali je oko 30 puta skuplji. Cilj ove studije je bio da pokaže da li je sa aspekta odnosa troškova i efikasnosti opravdano finansiranje korišćenja fidaksomicina u praksi od strane fonda zdravstvenog osiguranja u Srbiji. METOD:Studija je sprovedena kroz izradu farmakoekonomskog Markovljevog modela, koji je uporedio odnos troškova i efikasnosti fidaksomicina i vankomicina za oralnu upotrebu. Podaci o efikasnosti oba leka su bili preuzeti iz publikovanih kliničkih studija koje su metodološki validno urađene, dok su troškovi bili izračunati na osnovu vodiča za lečenje kolitisa izazvanog sa Clostridium difficile i cena lekova i usluga koje priznaje Republički fond za zdravstveno osiguranje u Srbiji (RFZO). U obzir su bili uzeti samo direktni troškovi lečenja, iz perspektive RFZO-a. Model ima 6 ciklusa u trajanju od 15 dana svaki. Za izradu modela je korišćen program Mikrosoft Ekscel 2007. REZULTATI:Inkrementalni odnos troškova i efekata kada se uporede fidaksomicin i vankomicin ukazuje da treba platiti 36,092,951.31 ± 956,719.68 (95% CI) dinara za jedan spašen život, koji bi se dobio primenom fidaksomicina umesto vankomicina. Inkrementalni odnos troškova i efekata kada se uporede fidaksomicin i vankomicin takođe ukazuje da treba platiti 124,455,232.90 ± 4,296,592.73 (95% CI) dinara za jednu izbegnutu totalnu kolektomiju, što bi se dobilo primenom fidaksomicina umesto vankomicina. ZAKLjUČAK:S obzirom da bi RFZO trebao da snosi troškove tretmana koji koštaju manje od 50 miliona dinara po spasenom životu, finansiranje fidaksomicina od strane RFZO-a je farmakoekonomski opravdano. Ukoliko RFZO prihvati da snosi troškove lečenja Clostridium difficile kolitisa fidaksomicinom, to će omogućiti manje smrtnih ishoda i manje totalnih kolektomija u Srbiji. In this pharmaco-economic study which was conducted using a Markov model compared the cost-effectiveness fidaxomicin and vancomycin for oral use. Data on the effectiveness of both drugs were taken from published and validly performed, clinical studies. Costs are calculated on the basis of guidelines for the treatment of colitis caused by Clostridium difficile and the prices of medicines and services that recognize the Republic Health Insurance Fund (RFZO) in Serbia. Only the direct costs of treatment were calculated according to the criteria RFZO's. The model had six cycles and each of them was during fifteen days. Microsoft Office Excel 2007 was used for modeling program. Incremental relationship between cost and effects when compared fidaxomicin and vancomycin show that should be payed 36,092,951.31 for one saved life, which would be obtained by applying fidaxomicin instead of vancomycin, while for one avoided total colectomy should pay 124,455,232.90 dinars. With regard to RFZO should bear the costs of treatments that cost less than 50 million for lifesaving, financing fidaxomicin by RFZO is pharmaco-economic justified. If RFZO accept to bear the cost of treatment of Clostridium difficile colitis using fidaxomicin it will happen less deaths and less total colectomy in Serbia.

Efekti jedinjenja paladijuma na kontraktilnost, koronarni protok i vijabilnost izolovanog srca pacova Perić, Tanja, 1981- Paladijum; jedinjenja paladijuma; kardiotoksičnost; citotoksičnost; antioksidant; trovanje paladijumom 54 Prethodne studije ukazale su na moguće antioksidativno i kardioprotektivno dejstvo izvesnih organskih jedinjenja paladijuma. Sprovedena je eksperimentalna studija na izolovanom srcu pacova, u cilju ispitivanja i upoređenja efekata organskih i neorganskih jedinjenja paladijuma na kontraktilnost, koronarni protok i vijabilnost srca. Značaj manje toksičnosti organskih jedinjenja ogleda se pre svega u lečenju pacijenata otrovanih paladijumom. Ispitivana jedinjenja su: trietanolamin (TEA), trietanolamin acetat (TEAA), trans-dihlorobis(trietanolamin-N)paladijum (II) kompleks i paladijum (II)-hlorid (PdCl2) u rastućim koncentracijama: od 10 ng/ml do 100 μg/ml. Registrovani su hemodinamski parametri (dP/dt max, SLVP, DLVP, MBP, HR, koronarni protok), a iz koronarnog venskog efluenta određivani su parametri oksidativnog stresa (NO, TBARS, O2ˉ, H2O2) i enzimi nekroze miokarda (AST, ALT, LDH, CK, CK-MB). PdCl2 je izazvao smanjenje kontraktilnosti srca koje se manifestovalo padom vrednosti dijastolnog i srednjeg pritiska u levoj komori. Ostala jedinjenja izazvala su smanjenje frekvence srca i koronarnog protoka, pri čemu su efekti PdCl2 bili znatno izraženiji od TEA i njegovog Pd(II) kompleksa. Ovakvi rezultati ukazuju na manju kardiotoksičnost organskih jedinjenja paladijuma. Ne postoji signifikantno pro- ili antioksidativno dejstvo jedinjenja paladijuma u kardiomiocitima, osim smanjenja indeksa lipidne peroksidacije dejstvom Pd kompleksa. Paladijum(II) jedinjenja ne pokazuju značajno citotoksično dejstvo na srčane ćelije. PdCl2 dovodi do statistički značajne inhibicije aktivnosti laktat dehidrogenaze (LDH), dok Pd kompleks izaziva statistički značajnu inhibiciju LDH, kreatin kinaze (CK) i njenog izoenzima MV (CK-MB), ali su apsolutni nivoi ispitivanih enzima ispod granice koja označava oštećenje ćelija. Prikazani rezultati u ovoj studiji, kao i dosadašnji dostupni rezultati istraživanja kontraverzni su po pitanju manje toksičnosti organskih jedinjenja paladijuma u odnosu na neorganska. Kardiotoksični efekti observirani u našoj studiji trebalo bi da inspirišu dalja istraživanja o toksičnosti paladijuma na ljudsku populaciju. Previous studies indicated the possibility of antioxidative and cardioprotective effects of certain organic palladium compounds. Experimental study was conducted on isolated rat heart to investigate and compare the effects of organic and inorganic palladium compounds on contractility, coronary flow and viability of the heart. The importance of less toxicity of organic palladium compounds is the treatment of poisoned patients with palladium. The investigated compounds were: triethanolamine (TEA), triethanolamine acetate (TEAA), trans-dihlorobis (triethanolamine-N) palladium (II) complex and the palladium (II) chloride (PdCl2) in increasing concentrations: from 10 ng / ml to 100 mg / ml. Hemodynamic parameters were registered (dP / dt max, SLVP, DLVP, MBP, HR, coronary flow), the parameters of oxidative stress (NO, TBARS, O 2 ˉ, H2O2) and enzymes of myocardial necrosis (AST, ALT, LDH, CK, CK-MB) were determined in the coronary venous effluent. PdCl2 reduced contractility of the heart by decreasing DLVP and MBP. Other compounds caused reduction of heart rate and coronary flow, whereas the effects of PdCl2 were much greater than the effects of TEA and its Pd (II) complex. These results indicate a lower cardiotoxicity of organic palladium compounds. There was no significant pro- or antioxidant activity of palladium compounds in cardiomyocytes, except the reduction of TBARS by Pd complex. Palladium (II) compounds didn’t show significant cytotoxic effects on heart cells. PdCl2 induced statistically significant inhibition of lactate dehydrogenase (LDH), while Pd complex caused statistically significant inhibition of LDH, creatine kinase (CK) and isoenzyme MB (CK-MB), but the absolute levels of investigated enzymes were under the limits which indicating the damage of the cells. This results and previous available research results of the less toxicity of organic palladium compounds in regard to inorganic are controversial. Cardiotoxic effects observed in our study should inspire further research Univerzitet u Kragujevcu Fakultet medicinskih nauka Janković, Slobodan, 1961- (ths, code: 07148) Milovanović, Dragan, 1967- (oth, code: 07175) Jakovljević, Vladimir, 1971- (oth, code: 07147) Đurić, Dragan, 1961- (oth, code: 01988) 2013 PhD thesis application/pdf http://eteze.kg.ac.rs/application/showtheses?thesesId=111 https://fedorakg.kg.ac.rs/fedora/get/o:163/bdef:Content/download https://plus.cobiss.net/cobiss/sr/sr/bib/519026069 sr Autorstvo-Nekomercijalno 3.0 Srbija (CC BY-NC 3.0)

Strategijsko upravljanje ljudskim resursima u ekonomiji zasnovanoj na znanju знању Strategic human resource management in the knowledge-based economy Slavković, Marko, 1980- Menadžment ljudskih resursa, menadžment znanja Menadžment znanja U radu su razmatrani najvažniji elementi strategijskpg upravljanja ljudskim resursima u kontekstu ekonomije u kojoj znanje ima status kritičnog resursa, čime je istovremeno opredeljen predmet istraživanja. Osnovni cilj istraživanja je da se dokaže da strategijsko upravljanje ljudskim resursima doprinosi poboljšanju organizacionih performansi i da su ljudski resursi važan faktor koji treba uzeti u obzir prilikom formulisanja organizacione strategije. U tom smislu, analizirani su ključni izazovi, različiti pristupi upravljanja ljudskim resursima i njihova uloga u kreiranju konkurentske prednosti. Formulisanje strategije upravljanja ljudskim resursima je posmatrano kroz moguće pristupe, proces i način usklađivanja sa organizacionom strategijom. Posebna pažnja je posvećena strategiji upravljanja znanjem, kako sa aspekta njenog formulisanja, tako i sa aspekta identifikovanja njenih ključnih elemenata. Istraživanje strategije upravljanja talentima je sprovedeno kroz analizu ključnih konstituenata i taktika i tehnika za upravljanjee talentima. Evaluacija strategije upravljanja ljudskim resursima je analizirana sa aspekta uticaja na organizacione performanse i kroz izbor alata i pokazatelja. Empirijskim istraživanjem je utvrđeno da praksa strategijskog upravljanja ljudskim resursima, strategija upravljanja znanjem i strategija upravljanja talentima imaju ppzitivan uticaj na organizacione performanse i inovativnost, respektivno, čime se opravdanim smatraju ulaganja u razvoj jedinstvene prakse i u aktivnosti koje se odnose na kreiranje, usvajanje, deljenje i primenu znanja, odnosno na formiranje i održavanje pula talenata u okviru organizacije. The paper discusses the most important elements of strategic human resource management in the context of the economy in which knowledge has the status of a critical resource, which is also defined subject of research. Main research objective is to prove that strategic human resource management contribute to improvement of organizational performance, and human resources are important factor which need to be considered during process of organizational strategy formulation. In this context,there have been analyzed the key challenges, different approaches to human resources management and their role in creating competitive advantage. Formulation of HR strategy is considered through possible approaches, process, and fit with the organizational strategy. Special attention was paid to the knowledge management strategy, both in terms of its formulation, but also in terms of identifying its key elements. The research of talent management strategy is done through the analysis of key constituents and tactics and techniques for talent management. Evaluation of HR strategy is analyzed from the point of impact on organizational performance and the selection of tools and indicators. Results of empirical research show that strategic human resource practice, knowledge management strategy, and talent management strategy have positive impact on organizational performance and innovation, respectively, which justifies investments in development of unique practice and activities related to creating, capturing, sharing, and using knowledge, as well as forming and retaining pull of talents within organization.

Obračun troškova po aktivnostima baziran na vremenu - instrument integrisanog upravljanja lean poslovnim procesima Todorović, Mirjana, 1979- Lean preduzeća, Lean upravljačko računovodstvo Lean menadžment Postizanje, očuvanje i jačanje konkurentske prednosti predstavlja ključni faktor opstanka i uspešnosti poslovanja savremenih preduzeća. Preduzeća definišući svoju misiju, viziju i ciljeve, odnosno na bazi toga formulišući strategije, upravo teže da deluju u tom pravcu. Konstantna komponenta strategije savremenih preduzeća podrazumeva kontinuirane napore ka unapređenju poslovnih procesa (poslovanja). Kontinuirana, operativna unapređenja poslovnih procesa su u fokusu velikog broja istraživača – teoretičara i praktičara i u vezi sa njihovom realizacijom razvijeni su brojni upravljački instrumenti. Instrument koji je pokazao izuzetnu efikasnost za svrhe kontinuiranih unapređen ja je upravo lean koncept. Njegova suština je u kontinuiranoj težnji ka redukciji troškova kroz unapređenje poslovnih procesa i eliminisanje svih oblika nepotrebnih trošenja (rasipanja, gubitaka), ali i u unapređenju znanja, veština i kompetencija zaposlenih. Budući da osnovu efikasnog upravljanja čine kvalitetni procesi merenja, u vezi sa lean upravljanjem predlažu se i kreiraju različite metodologije i pristupi merenja njegovih efekata. Neke od njih se vezuju isključivo za lean poslovno okruženje, dok su druge nastale kao samostalni koncepti. Posebno pogodan za uslove lean poslovnog okruženja i merenje efekata napora ka kontinuiranim unapređenjima, prema mišljenju velikog broja stručnjaka, pojavio se obračun troškova po aktivnostima zasnovan na vremenu (Time-Driver Activity Based Costing - TDABC). TDABC sistem se smatra svojevrsnim finansijskim termometrom efekata primene lean koncepta. Reč je o savremenom sistemu obračuna i upravljanja troškovima, koji podrazumeva unapređenu metodologiju obračuna troškova, zasnovanu na jednačinama vremena i vremenskim uzročnicima troškova. Ovaj sistem obračuna u težnji ka što preciznijem utvrđivanju troškova proizvoda, istim dodeljuje samo troškove stvarno potrošenog kapaciteta a ne i troškove neiskorišćenog kapaciteta, koji zapravo imaju tretman troškova perioda. Imajući u vidu učestalost primene TDABC sistema u uslovima lean poslovnog okruženja, danas se sve više govori o primeni integrisanog Lean TDABC pristupa. Integrisani pristup je nastao na osnovama visoke kompatibilnosti i komplementarnosti TDABC sistema i lean koncepta, te pruža preduzećima brojne strategijske i operativne koristi. Achieving, maintaining, and strengthening competitive advantage is a key factor in the survival and success of the contemporary companies. The companies, by defining their mission, vision, and goals, and formulating their strategy based on this, strive to attain the above mentioned. The constant strategy component of contemporary companies involves continuous efforts to improve business. Continuous and operational improvement of business processes are the focus of many researchers – theoreticians and practitioners. In relation to their implementation, numerous management tools have been developed. The tool which has demonstrated high efficiency for the purpose of continuous improvement is the lean concept. Its essence is in the constant pursuit of cost reduction through the improvement of business processes and elimination of all forms of waste, but also in the improvement of knowledge, skills, and competencies of employees. Since the foundation of an effective management is the quality measurement process, in relation to the lean management, various methodologies and approaches to measuring its effects are being proposed and created. Some of them are related solely to lean business environment, while others are created as independent concepts. In the opinion of many experts, the system which emerged as the particularly suitable for the conditions of lean business environment and measurement of the effects of effort toward continuous improvement is Time-Driver Activity Based Costing - TDABC. TDABC system is considered as a kind of “financial thermometer” of the effects of lean concept application. It is a contemporary cost accounting and cost management system, which includes an improved methodology for cost accounting, based on time equations and time drivers. TDABC in the pursuit of a more precise determination of product costs, assigns them only the costs of really consumed capacity but not the costs of unused capacity, which are actually period costs. Given the frequency of the TDABC system application in terms of lean business environment, today there is more and more talk about the application of an integrated Lean TDABC approach. The integrated approach is based on the high compatibility and complementarity of the TDABC system and lean concept, and provides companies a number of strategic and operational benefits.

Dijagnostički značaj određivanja nivoa lipokalina udruženog sa neutrofilnom gelatinazom u urinu kod bolesnika sa lupus nefritisom Diagnostic significance determining the level of urinary neutrophil gelatinasa associated lipocalin in patients with lupus nephritis Rabrenović, Violeta, 1963- Lupus nefritis, urinarni biomarker 616 U prospektivnoj kliničkoj studiji na 40 bolesnika sa lupus nefritisom, ispitivan je značaj određivanja urinarnog biomarkera: Lipo-kalina udruženog sa neutrofilnom gelatinazom (NGAL). Cilj studije bilo je praćenje i poređenje odnosa parametara aktivnosti lupus nefritisa, između ispitivane i kontrolne grupe (po 20 bolesnika) na početku lečenja i 2 i 4 meseca po započinjanju lečenja. Statistički značajne korelacije dobijene su između urinarnog NGAL-a i anti ds-DNA antitela, 24č. proteinurije, odnosa urinarnih proteina i kreatinina (Upr/kre), SLEDAI/r skora. Poređenjem sa drugim parametrima aktivnosti lupus nefritisa, zapaženo je da je u/NGAL statistički najsignifikantniji pokazatelj. Rezultati su ukazali na značaj u dijagnostikovanju aktivnosti bolesti, odnosno potvrdi remisije lupus nefritisa, čime se može primeniti adekvatniji terapijski modalitet i individualni pristup lečenju. Ova studija ukazuje da bi određivanje urinar- nog NGAL kod bolesnika sa lupus nefritisom u svakodnevnom kliničkom radu doprinelo najoptimalnijem učinku lečenja. In a prospective clinical study of 40 patients with lupus nephritis, we examined signifi cance of determining urinary biomarker Neutrophil gelatinase-associated lipocalin (uNGAL). The aim of the study was to monitor and compare the parameters of activity of lupus nephritis, between the examined and control groups of 20 patients each, at baseline, and 2 and 4 months after the start of treatment. Statistically signifi cant correlations were obtained between urinary NGAL, and anti-ds DNA antibodies, 24h. proteinuria, urinary protein to creatinine ratio (Upr/cr), and SLEDAI / r score. Comparing with other parameters of activity of lupus nephritis, it was noticed that uNGAL is the most statistically signifi cant parameter. The results show the importance in the diagnosis of disease activity, and in confi rmation of remission of lupus nephritis, which can result in application of more appropriate therapeutic modality and individual approach to treatment. This study suggests that the determination of uNGAL in patients with lupus nephritis in daily clinical practice can contribute to the optimal eff ect of treatment.

Evaluacija promene inflamatornih medijatora i redoks ravnoteže izazvane šestomesečnim treningom Evaluation of changes in inflammatory mediators and redox balance caused by the six-month training Lazarević, Predrag, 1972- Oksidativni stres, antioksidativna zaštita, inflamatorni medijatori, fudbal, trenažni proces antioksidativna zaštita Istraživanje je koncipirano tako da ispita uticaj programiranog fizičkog vežbanja na aktivnost pro i antiinflamatornih citokina i oksidativnih enzima, kao i na morfo-funkcionalne parametre. Korelacijom je dokazivana jačina povezanosti svih oksidativnih enzima, inflamatornih citokina, i morfo-funkcionalnih parametara nakon sprovedenog šestomesečnog trenažnog ciklusa. Svi rezultati sportista su upoređivani sa vrednostima nesportista u mirovanju. Prvi deo istraživanja obuhvatio je 28 fudbalera, starosti 12-13 godina i najmanje petogodišnjim trenažnim iskustvom, i 28 dečaka iste starosti, koji nemaju programiranu fizičku aktivnost. Svi su podvrgnuti merenju telesne kompozicije. Prvi deo istraživanja sastojao se od uzimanja uzoraka krvi u miru i nakon progresivno rastućeg testa opterećenja radi određivanja nivoa biohemijskih parametara oksidativnog stresa (superoksid anjon radikal, vodonik peroksid, azot monoksid, indeks lipidne peroksidacije, superoksid dismutaza,katalaza i redukovani glutation) i inflamatornih citokina (tumorske nekroze faktor alfa i interleukina 6). Drugi deo istraživanja je obuhvatao samo sportiste. Ponovljen je progresivni rastući test opterećenja kao i uzimanje uzoraka venske krvi radi ponovljenih biohemijskih testova svih parametara oksidativnog stresa i inflamatornih citokina u cilju procene nivoa njihove aktivnosti nakon sprovedenog šestomesečnog programa treninga. Rezultati naše studije pokazuju da programiran trenažni proces dovodi do pozitivne aktivacije antioksidativnih enzima prvog odbrambenog zida, sniženog inflamatornog odgovora i pozitivnih morfo - funkcionalnih promena. Korelacija redoks ravnoteže i praćenih citokina pokazuje nisku povezanost. Morfo-funkcionalni parametri pokazuju slabu ili nikakvu povezanost sa redoks ravnotežom i inflamatornim citokinima. The research was designed to examine the effects of programmed physical exercise on the activity of pro- and anti-inflammatory cytokines and oxidative enzymes, as well as on the morpho-functional parameters. The correlation was used to assess the strength of relationship between oxidative enzymes, inflamatory citokines and morphofunctional parameters after 6 months of programmed football training. All the results of athletes were compared with results of non athletes at rest. The investigation included 28 players with minimum 5 years of sports experience, aged 12-13 years, and 28 age/matched boys not engaged in physical activity. All underwent measurement of body composition.The first part of the research included blood sampling at rest and after progressively increasing load test to determine the levels of biochemical parameters of oxidative stress (superoxide anion radical, hydrogen peroxide, nitric oxide, index of lipid peroxidation, superoxide dismutase, catalase and reduced glutathione) and inflammatory cytokines (tumor necrosis factor alpha and interleukin 6). The second part of the study included only the athletes. Progressively increasing load test was performed and venous blood samples taken in order to assess changes in biochemical parameters of oxidative stress and inflammation due to six/month training programme. The results of the research show that programmed training leads to positive activation of antioxidative enzymes of the first defense wall, decreased inflamatory response and positive morphofunctional changes. Correlation of redox balance and monitored cytokines showed a low relationship. Morpho - functional parameters showed poor or no correlation with the redox balance and inflammatory cytokines.

Faktori rizika za zloupotrebu psihoaktivnih supstanci kod mladih u Srbiji Risk factors for psychoactive substances abuse among young people in Serbia Radovanović, Snežana, 1971- Psihoaktivne supstance, adolescencija, duvan, alkohol, droga adolescencija Doktorska disertacija predstavlja studiju kojom je procenjen značaj problema zloupotrebe psihoaktivnih supstanci kod mladih uzrasta 12-19 godina u Srbiji, kojom su ispitani i utvrđeni faktori rizika za zlpupotrebu psihoaktivnih supstanci ove populacione grupe. U istraživanju je primenjen dizajn studije preseka, na reprezentativnom uzorku stanovništva Srbije kao celine i stanovništva velikih područja (Centralna Srbija, Vojvodina, Beograd), po polu, starosti i mestu življenja. Uzorak ovog istraživanja čini 1939 ispitanika starosti 12-19 godina ekstrahovan iz uzorka stanovništva Srbije formiranog za potrebe istraživanja u okviru Projekta ,,Zdravstveno stanje, zdravstvene potrebe i korišćenje zdravstvene zaštite stanovništva Srbije“ sprovedenog 2006. godine. Izvor podataka o odabranim obeležjima čini posebno konstruisan Upitnik za decu i omladinu uzrasta od 7 do 19 godina. Svi podaci iz anketnih upitnika su prikazani i analizirani adekvatnim statističkim metodama primerenim tipu i vrsti podataka. Najznačajniji rezultati istraživanja su da ispitanici koji imaju lošiji uspeh u školi 16 puta češće puše od onih koji imaju odličan uspeh. Mladi čiji drugovi puše, 13 puta češće puše od onih čiji drugovi ne puše, dok 9 puta češće puše ispitanici koji potiču iz porodica čiji su članovi pušači. Alkoholna pića 4 puta češće piju ispitanici koji puše, 3 puta češće ispitanici koji koriste opijate, dok ispitanici koji imaju ispravan (negativan) stav prema alkoholu 3 puta manje piju. Mladi u Srbiji su u najvećem procentu probali marihuanu, tablete (bensedin, trodon, amfetamin) i lepak. U slučajevima kada neko od društva koristi drogu ispitanici 7,5 puta češće koriste drogu što pokazuje da je vršnjački uticaj na konzumiranje psihoaktivnih supstanci veliki. Na osnovu navedenih zaključaka sledi da je neophodno intenzivirati preventivne aktivnosti kao i uključivanje mladih u timove za kreiranje preventivnih programa kao ključnih prenosioca poruka koje imaju za cilj sprečavanje započinjanja upotrebe psihoaktivnih supstanci. Doctoral dissertation presents a study that assessed the importance of the problem of psychoactive substances abuse among young people aged 12-19 years in Serbia, and which allowed risk factors for psychoactive substances abuse for this population to be tested and identified. We have applied a cross-sectional study design on a representative sample of the population of Serbia as a whole, and residents of large areas (Central Serbia, Vojvodina, Belgrade), by sex, age and place of living. The sample of this research, which included 1939 respondents aged 12-19 years, was extracted from a sample of the population of Serbia, formed for the purpose of research in the project „Health status, health needs and use of health services in Serbia“ conducted in year 2006th. Source of information on the selected features was the specially designed questionnaire for children and adolescents aged 7 to 19 years. All data from questionnaires are presented and analyzed using appropriate statistical methods in accordance with the data type. The most important results of the research were that subjects who have worse school grades are 16 times more likely to smoke than those who have a good academic record. Young, whose friends smoke, are 13 times more likely to smoke than those whose friends do not smoke, and 9 times more likely to smoke are respondents that come from families whose members are smokers. Respondents who smoke consume alcoholic drinks 4 times more frequent, three times more respondents who use opiates, while respondents with the correct (negative) attitude towards alcohol drink alcohol 3 times less. Young people in Serbia in the highest percentage tried marijuana, pills (bensedin, Trodon, amphetamine) and glue. In cases where one of members of the company use drugs, respondents use drugs 7.5 times more likely, which indicates that the peer influence on psychoactive substances abuse is significant. Based on these findings, it can be concluded that it is necessary to intensify preventive actions and the involvement of young people, as key messengers, in teams for creating prevention programs that aim to prevent initiation of psychoactive substances abuse.

Identifikacija karakteristika multiprocesnog rada klipnom motora SUS Davinić, Aleksandar Lj., 1962- Motorna vozila Reciprocating internal combustion engines are dominantly applied in road transport means.Their mass use rapidly depletes the energy resources and creates ecological problems. Strict regulations regarding emissions of carbon-dioxide, toxic gases, particulates and noise are effective today. Modern technology has not jet given the suitable alternative in terms of performance and overall energy efficiency, so the internal combustion engines will be the basis for vehicle drives for many years to come. Internal combustion engine’s economy and emissions largely depend on the characteristics of the work process, thus development in this area has a great potential. In addition to original Otto and Diesel concepts, work processes combining their good qualities are also in use. Increase of efficiency and reduction of raw emissions are achieved by application of multiprocessing working principle, where the working zone of the engine is divided into zones with different operating modes. The subject of this dissertation is to identify the influence of the working parameters and the type of fuel (classical or bio-fuels) on characteristics of individual work processes of multiprocessing Otto/Diesel engine. The research was conducted on original experimental engine with application of standard European stationary test. The influence of compression ratio, type of fuel and control parameters on efficiency and exhaust emissions is observed. The summarized results of the test and the results obtained in individual test regimes are shown. Also, an example of defining the Otto or Diesel working areas is given according to the criteria of efficiency and particulate emissions.

Teorijsko-metodološki problemi revizije finansijskih izveštaja turističkih preduzeća Vasiljević, Momčilo S. 1972- turistička preduzeća, vrste turističkih usluga, računovodstveno obuhvtanje, revizorski postupci, bilansne pozicije, mišljenje revizora 657 U promenljivom okruženju od revizora se ne traži da overi istorijske informacije u finansijskim izveštajima klijenta, već da gleda u budućnost i da bude spreman da drži korak s promenljivim potrebama javnosti, kao i s promenama u korporativnoj strukturi, finansijskom tržištu, informatičkim i komunikacionim tehnologijama. Investitori traže bolju zaštitu, veći kvalitet informacija (u smislu tačnosti i pravovremenosti) za finansijsko tržište, veću odgovornost i kontrolu nad postupcima korporativnih rukovodilaca i revizorskih firmi. U skladu sa promenama u turbulentnom okruženju i zahtevima investitora svakako da revizori specijalisti za pojedine delatnosti (npr. ugostiteljstvo, turizam, osiguranje i slično) mogu kvalitetnije odgovoriti ovim promenama i zahtevima. Uvažavajući predmet i cilj istraživanja, postavljene hipoteze i primenjene metode istraživanja u disertaciji su analizirani teorijsko-metodološki problemi revizije turističkih preduzeća. Eksterni revizori, koji bolje poznaju delatnost ugostiteljstva i turizma, spremniji su da definišu kvalitetniji plan revizije i da na efikasan i efektivan način obave proces revizije iz razloga dobrog poznavanja vrsta usluga koje se pružaju u ovim preduzećima i standardizovanog načina knjigovodstvenog obuhvatanja ovih usluga. Kroz disertaciju istraživanje je usmereno na identifikovanje usluga pomenutih delatnosti, način njihovog obuhvatanja u poslovnim knjigama, ukazano na specifičnosti forme i sadržine finansijskih izveštaja ovih preduzeća i na kraju analizirani problemi koji se mogu javiti prilikom revizije finansijskih izveštaja turističkih preduzeća. Identifikovane su specifične bilansne pozicije u turističkim preduzećima polazeći od vrste I obima usluga koje se pružaju. Prestavljene su procedure revizorskih ispitivanja specifičnih bilansnih pozicija ugostiteljskih i turističkih preduzeća. Eksterni revizor izražavanjem mišljenja o finansijskim izveštajima ugostiteljskih ili/i turističkih preduzeća daje najviši nivo uveravanja licima koja su zainteresovana za finansijske informacije ovih preduzeća. The changing environment is not required from the auditor to certify the historical information in the financial statements the client, but to look to the future and be prepared to keep pace with the changing needs of the public, as well as changes in corporate structure, financial markets, information and communication technologies. Investors want better protection, higher quality information (in terms of accuracy and timeliness) for the financial markets, greater responsibility and control over the actions of corporate executives and audit firms. In accordance with the changes in the turbulent environment and requirements of investors certainly auditors specialists for specific activities (eg, catering, tourism, insurance and the like) can better respond to these changes and requirements. Taking into account the object and purpose of the research, hypotheses and research methods applied in the dissertation analyzes the theoretical and methodological problems in revision of tourism enterprises. External auditors who know better catering and tourism activity are more likely to define the high- quality audit plan and to efficiently and effectively carry out the audit process because a good knowledge of the types of services provided in these companies and standardized ways of accounting includings these services. Throughout the thesis we focused research on identifying the services mentioned activities, way of their including in business accounting books, showed the specific form and content of the financial statements of these companies and ultimately analyzed the problems that may arise during the audit of the financial statements of tourism enterprises. They identified specific balance sheet items in the tourist business starting from the type and volume of services provided. Audit testing procedures specific balance sheet items in catering and tourism companies are presented. The external auditor is expressing an opinion on the financial statements or hospitality / tourism enterprises and provides the highest level of assurance to persons who are interested in financial information to these companies.

Sinteza mehatroničnog sistema za izradu specijalno oblikovanih žičanih profila Milićević, Ivan, 1973- Mehatronički sistemi 621 Predmet ovog rada su teorijsko-eksperimentalna istraživanja projektovanja složenih tehničkih sistema na primeru realizacije mehatroničkog sistema za izradu specijalno oblikovanih žičanih profila (skraćeno, linija MSŽ). Proizvodi koji se dobijaju na liniji MSŽ su specijalni žičani profili poprečnog preseka trapeznog oblika, prstenasto savijeni na određenom koraku radi dalje montaže u finalni proizvod, strogih zahteva kvaliteta (potrebna tvrdoća, uske tolerancije mera oblika i dimenzija, itd). Profili se izrađuju od žice kružnog poprečnog preseka, prečnika Ø2÷5 mm, uglavnom od kvalitetnih nerđajućih čelika u normalizovanom stanju. Dobijeni žičani profili koriste se za formiranje tzv. pukotinastih sita (u svetu poznata kao Looped Wedge Wire Screens). The paper is focusing theoretical and experimental research of design of complex technical systems on the example of realization of mechatronic system for production of specially-designed wire profile (abbreviated MSZ). Products obtained on the MSZ are specially designed wire profiles wedge shaped and looped on a certain step for further assembly into final products having strict quality requirements (high hardness, tight tolerances of the dimensions shape and size, etc.). Profiles are fabricated from circular cross section wire with diameter of Ø2-5 mm, mainly high-quality stainless steel in the normalized condition. Obtained wire profiles are used for production of socalled Looped Wedge Wire Screens. System complexity enables all challenges of the mechatronic systems design to be shown, to perform all the necessary analysis both analytical and experimental, and to define mechatronic system with best characteristics by the synthesis of relevant data. Along with prototype realization an integrated design methodology of complex technical systems has been developed. Specific requirements are defined and many problems of theoretical and practical character have been solved. Certain experimental measurements were performed to verify obtained analytical results. Process parameters and particular solutions for specific segments of the system are defined by a modeling, simulation and analysis.

Uticaj parametara sinteze i strukture na električna svojstva Ba0,77Sr0,23TiO3 keramike The Influence of the Synthesis Parameters and Structure on the Electrical Properties of Ba0.77Sr0.23TiO3 Ceramics Kosanović, Darko, 1982- Keramika sinterovanje Rezultati istraživanja u oblasti elektronske keramike u najvećoj meri direktno zavise od poznavanja procesa konsolidacije (presovanje i sinterovanje) keramičkih prahova, što, posmatrano sa gledišta poimanja prirode, ukazuje na univerzalnost ovoga procesa. Razvoj savremenih keramičkih materijala omogućen je zahvaljujući multidisciplitarnom proučavanju i doprinosu istraživanja u različitim oblastima kao što su nauka o materijalima, fizika, hemija i elektronika. Rezultati naučnog i tehnološkog istraživanja objavljuju se u različitim naučnim publikacijama, što je izraz velikog značaja elektronske keramike u savremenoj tehnici. Prema aktuelnim naučnim istraživanjima koja se odnose na projektovanje i razvoj novih elektronskih keramičkih komponenti (izolatorska, termistorska, elektrooptička, piezoelektrična keramika, memorijski uređaji na bazi feroelektrične keramike itd.), BST keramika kao i jedinjenja sa strukturom perovskita su od posebnog interesa. Kondenzatorska keramika na bazi BST obuhvata: visokofrekventne kondenzatore (promenljivi, nelinearni kondenzatori čija se električna kapacitivnost jako menja sa promenom primenjenog napona), višeslojne kondenzatore sa relativnom dielektričnom konstantom εr (1-15)·103 (zastupljene u tehnologiji debeloslojnih hibridnih kola), čip-kondenzatore sa barijernim slojem kod kojih je εr (20-80)·103, itd. U okviru ove grupe materijala, višeslojni keramički kondenzatori (MLCCs - Multi Layer Ceramic Capacitor) su već duže vreme jedan od najvažnijih i široko korišćenih pasivnih komponenti u elektronskoj industriji. Takođe, BST je široko proučavan i razvijan za potencijalnu primenu u dinamičkim «random access» memorijama i u NVRAM uređajima sa nedestruktivnom modom očitavanja. Tanki filmovi BST pokazuju prednosti u nizu primena, kako u memorijskim elementima u NVRAM i DRAM uređajima (u kompjuterima, mobilnim telefonima, digitalnim kamerama, MP3 plejerima i mnoštvu drugih portabl uređaja), tako i u elektrooptičkim prekidačima, optičkim talasovodima, piroelektričnim detektorima, optičkim modulatorima, itd. Barijum-stroncijum-titanat, Ba1-xSrxTiO3, (BST) je feroelektrični materijal sa tetragonalnom strukturom na sobnoj temperaturi za x<0,3, koji ima perovskitnu strukturu (ABO3). BST je čvrst rastvor sastavljen od titanata, barijum-titanata (BaTiO3) i stroncijum-titanata (SrTiO3). BaTiO3 je feroelektrični materijal sa Kirijevom temperaturom (Tc =393K), dok je SrTiO3 paraelektrični materijal sa neferoelektričnim faznim transformacijama kod koga je Kiri temperatura (Tc =105K). Na sobnoj temperaturi za sistem čvrstog rastvora u feroelektričnoj fazi sadržaj Ba je u opsegu od 0,7 do 1,0; dok je sadržaj Ba u paraelektričnoj fazi manji od 0,7. Kirijeva temperatura BST linearno opada sa povećanjem koncentracije Sr. Zbog toga Kiri temperatura BST a samim tim i njene osobine mogu biti prilagođene širokom opsegu da bi se zadovoljili zahtevi različitih primena. Ova vrsta fleksibilnosti osobina a samim tim i potencijalni opseg primene nije prisutan kod konvencionalne feroelektrične keramike. Postoji nekoliko različitih metoda za sintezu praha Ba1-xSrxTiO3, bilo suvom ili mokrom hemijskom sintezom. Prva grupa metoda zasnovanih na reakcijama u čvrstom stanju, su i najčešće metode za dobijanje BST dok su u drugoj grupi ko-precipitacija, sprej piroliza i neke sol-gel tehnike. Među njima su i hidrotermalne tehnike koje predstavljaju komercijalan način za dobijanje datog materijala. Svaka od ovih metoda ima svoje prednosti i mane. Neke od tih prednosti su dobijanje superfinog praha visoke čistoće i nizak stepen aglomeracije, dok su nedostaci visoka temperatura kalcinacije (od 1000oC do 1200oC), zatim korišćenje veće količine početnog praha, velika veličina zrna zbog čega se ne mogu koristiti za dobijanje materijala sa velikom dielektričnom konstantom. U skorije vreme u cilju sniženja temperature kalcinacije i dobijanja materijala definisane mikrostrukture, sve više se koristi i metoda mehaničke aktivacije. Cilj ovog rada je da pokaže uticaj mehaničke aktivacije i režima sinterovanja na promenu strukture i električna svojstva BST keramike. Na osnovu detaljne analize temperaturske zavisnosti, realne dielektrične propustljivosti i tangensa ugla gubitaka, kao i uticaja mehaničke aktivacije na promenu frekventnih karakteristika biće definisani optimalni tehnološki parametri za dobijanje Ba0,77Sr0,23TiO3 keramike unapređenih električnih karakteristika.

Deformaciono ponašanje i karakteristike loma Al-Mg legura u svetlu međuzavisnosti sastav - tehnologija - struktura Radović, Ljubica M., 1966- Legure Al-Mg U radu je ispitan uticaj tehnologije prerade, rotacionog valjanja konusa i valjanja glatkim valjcima na strukturu, fizička i mehanička svojstva Al-Mg legura različitog hemijskog sastava. Korišćene su tri komercijalne Al-Mg legure AlMg3, AlMg4,5Mn i AlMg6Mn, a primenom različitih režima termomehaničke prerade dobijena su dva stukturna stanja u pogledu veličine zrna. Homogena sitnozrna struktura, sa srednjom veličinom zrna kod svih legura 13-14 μm, i krupnozrna, sa veličinom zrna u intervalu od 20-50 μm. Rotacionim valjanjem oblikovani su konusi korišćenjem trnova sa uglovima 2α=90°, 60°, 40° i 18°, pri čemu su ostvarena 4 stepena deformacije: 30 %, 50 %, 66 % i 84 %, respektivno. Za ispitivanje strukturnih i mehaničkih svojstava Al-Mg legura u polaznom stanju i nakon deformacije, u funkciji sadržaja Mg, veličine zrna, stepena deformacije i primenjene tehnologije plastične prerade, korišćene su optička mikroskopija (OM), skenirajuća elektronska mikroskopija sa enegrodisperzionom analizom h-zraka (SEM/EDS), transmisiona elektronska mikroskopija (TEM), test jednoosnim zatezanjem i merenje tvrdoće i električne provodljivosti. Sa povećanjem stepena deformacije, povećanjem sadržaja Mg u leguri i smanjenjem veličine zrna, dolazi do povećanja granice tečenja i zatezne čvrstoće. Pokazano je da pri deformaciji rotacionim valjanjem, za razliku od valjanja glatkim valjcima, dolazi do pojave dinamičkog oporavljanja, što se odrazilo na deformaciono ponašanje pri jednoosnom zatezanju i mehanička svojstva. Mehanička svojstva rotaciono valjanih uzoraka su niže nego kod uzoraka valjanih glatkim valjcima sa istim stepenom deformacije. Dinamičko oporavljanje dovodi do povećanja plastičnosti Al-Mg legura. Pretpostavljeno je da je pojava dinamičkog oporavljanja pri rotacionom valjanju posledica velike brzine deformacije i adijabatskog zagrevanja u uskoj zoni deformacije. Lom rotaciono valjanih uzorka od Al-Mg legura pri jednoosnom zatezanju se odvija duktilnim mehanizmom. Dominanatan uticaj na karakteristike loma Al-Mg legura su pokazali veličina i raspodela čestica sekundarnih faza. Krupne čestice sekundarnih faza predstavljaju mesta za nukleaciju mikrošupljina za vreme deformacije i ograničavaju duktilnost i sposobnost oblikovanja. Uspostavljena je veza između polazne mikrostrukture, čvrstoće i duktilnosti sa karakteristikama površine preloma Al-Mg legura. The development of the microstructures, and changes of the mechanical and phisical properties during deformation of Al-Mg alloys (3-6 % Mg) by shear spinning and cold rolling were investigated. Four mandrels with different angles of 2α=90°, 60°, 40° and 18°, were used for shear spinning, and reduction of 30%, 50%, 66% и 84 % were achieved, respectively. The microstructure and mechanical properties in annealed and deformed Al-Mg alloys were examined by means of optical microscopy, SEM/EDS, TEM, tensile testing, hardness and electrical conductivity measurement. With increase of reduction and Mg content, as well as decrease of the grain size, the yield stress and ultimate tensile strength of Al-Mg alloys increase. It was shown that during shear spinning, unlike cold rolling, dynamic recovery occurres, what affect the deformation behaviour during tensile test and mechanical properties. Mechanical properties of Al-Mg alloys after shear spinning are lower compared to cold rolling at the same reduction. Dynamic recovery increases the plasticity of Al-Mg alloys. It was assumed that dynamic recovery during shear spinning is result of high strain rate and adiabatic heating in a small deformation zone. Fracture of shear spun specimens during uniaxial tensile occure by ductile mechanism. The size and distribution of the second phase particles showed the dominant influence on the fracture.

Optimizacija zatvorenih poprečnih preseka glavnih nosača dizalica primenom metode Lagranžovih množitelja Pavlović, Goran V., 1977- Dizalice mosna dizalica Rad pod nazivom „OPTIMIZACIJA ZATVORENIH POPREČNIH PRESEKA GLAVNIH NOSAČA DIZALICA PRIMENOM METODE LAGRANŽOVIH MNOŽITELjA", razmatra problem optimizacije sandučastih poprečnih preseka glavnog nosča dizaličnih konstrukcija, kao njenog najodgovornijeg dela. Kao funkcija cilja, postavljeno je smanjenje mase glavnog nosača. Metda Lagranžovih množitelja je korišćena kao metodologija za računanje optimalnih zavisnosti geometrijskih parametara sandučastih poprečnih preseka. Kao funkcije ograničenja krišćene su kriterijumi čvrstoće, bočne stabilnosti, lokalne stabilnosti limova, krutosti nosača i dinamičke krutosti. Dobijeni rezultati geometrijskih parametara optimizacije potvrđeni su na numeričkim primerima i izvršeno je njihovo poređenje sa izvedenim rešenjima. Komparativana analiza rezultata optimizacije i rešenja bila bi osnova za preporuke koje su od značaja za projektante u procesu projektovanja dizaličnih konstrukcija. Težište rada bazirano je na istraživanju i ispitivanju optimalnih vrednosti i međusobnih zavisnosti geometrijskih parametara sandučastog poprečnog preseka glavnog nosača koji utiču na povećanje savojne i torzione krutosti, smanjenje lokalnog naprezanja u karakterističnim presecima i smanjenje površine poprečnog preseka, odnosno količine utrošenog materijala za njegovu izradu, pri čemu je zadovoljena osnovna funkcija rada dizalice. Istraživane su međusobne zavisnosti geometrijskih parametara poprečnog preseka, odnosno njihov odnos, primenom metode Lagranžovih množitelja prema karakterističnim kriterijumima, pri čemu je prikazan algoritam izbora optimalnog kriterijuma i određivanja optimalnih geometrijskih parametara poprečnog preseka. Na taj način određeni su karakteristični kriterijumi za određene raspone i nosivosti za pogonsku klasu 2, u zavisnosti od izbora materijala. Takođe, prikazana je zavisnost odnosa optimalnih geometrijskih parametara za karakteristične nosivosti u odnosu na promenu raspona. Izvršena je potvrda opravdanosti primene dobijenog algoritma, pri čemu je prikazana ušteda koja se ovim postupkom dobija u odnosu na izvedena rešenja dvogrednih mosnih dizalica. The paper entitled „OPTIMIZATION OF THE CLOSED CROSS SECTIONS OF THE MAIN MAIN GIRDERS OF THE CRANES BY USING THE METHOD OF LAGRANGE MULTIPLIERS", considers the problem of optimization of the box section of the main girder of the construction of cranes, as its most liable part. Reduction of the girder mass is set as the objective function. The method of Lagrange multipliers was used as the methodology for approximate determination of optimum dependences of geometrical parameters of the box section. The criteria of permissible stresses and strains, lateral stability, local stability of plates, girder stiffness and dynamic stiffness were applied as the constraint functions. The obtained results of optimization of geometrical parameters were verified on numerical examples and the comparison with some solutions of cranes was made. The comparative analysis of the optimization results and the solutions was the basis for recommendations which are significant for designers during construction of cranes. The focus of work is based on research and testing of optimal values and the mutual dependence of geometric parameters of rectangular box cross-section of the main girder affecting the increase in bending and torsion stiffness, reduction of local strain in the characteristic cross sections and reduction the cross-section area, that is quantity of materials used for its manufacture, whereby the basic function of crane is fulfilled. Research on the mutual dependence of geometric parameters of cross section, and their ratio, using the method of Lagrange multiplier as characteristic criteria is done, whereby is shown algorithm for selection of the optimal criteria and determining the optimal geometric parameters of cross section. In this way the characteristic criteria are specificied for a particular span and capacity of work regime 2m, depending on the choice of materials. Also it shows the dependency of the ratio of optimal geometrical parameters for the specific weight of load with respect to the span change. The application showed confirmation of acquired algorithm feasibility, whereby the savings are shown gained in this process with regard to the derived solution of the double beam crane bridges.

Uticaj informaciono - komunikacione tehnologije na postignuća učenika u nastavi prirode i društva The influence of information and communication technologies on student achievement in the subject nature and society Janković, Aleksandar, 1970- Priroda i društvo, nastava, metodika Nastava Vreme u kojem živimo najviše su obeležile nove informaciono-komunikacione tehnologije, odnosno računar, jer je primena istih u svakoj oblasti ljudskog rada dovela do značajnih unapređenja. Saglasno tome, kao i postojećim saznanjima o ulozi opažanja i drugih aktivnosti u procesu formiranja pojmova ili saznanja, očekuje se da primena multimedijalnih nastavnih sredstava, koje podržavaju pomenute tehnologije, može značajno uticati i na postignuća učenika. Da li je to slučaj u nastavi predmeta Priroda i društvo pitanje je koje se, u vidu problema naučnog istraživanja,postavlja u ovom radu. U poređenju sa tradicionalnim nastavnim sredstvima istraživan je uticaj mapa uma, video prezentacija, interneta i elektronske interaktivne table na postignuća učenika, a onda stavovi učenika i učitelja u odnosu na sva ova sredstva. Eksperiment sa paralelnim grupama izvršen je u populaciji učenika III razreda osnovne škole. Efekti delovanja pojedinih sredstava mereni su, međusobno upoređivani i analizirani u tri vremenska perioda. Time je utvrđeno: (1) da su savremena sredstva bila efikasnija od tradicionalnih, (2) da su se mape uma pokazale najefikasnijim, (3) da su tradicionalna sredstva, zbog najveće bliskosti izvornoj stvarnosti, i dalje značajna, (4) da je postignuće korespondiralo sa nivoom pozitivnosti stavova učenika i učitelja u odnosu na pojedina sredstva i (5) da nijedno sredstvo ne može biti potpuna zamena za bliskost kakva se postiže u neposrednoj interakciji između učenika i učitelja. The time in which we live has been profoundly influenced by the new information and communication technologies, or personal computers, since the implementation of these in every field of human activity has led to significant improvements. In accordance with this, as well as with the present knowledge on the role of perception and other activities in the process of forming concepts or knowledge, it is expected that the application of multimedia teaching tools,which are supported by the above mentioned technologies, can significantly affect student achievement. Whether this is the case in the teaching of the subject Nature and Society is an issue that is the focus of research of this dissertation. The research aim was to compare the influence of traditional teaching tools to that of mind maps, video presentations, the Internet and interactive whiteboard on student achievement,and to ascertain what the attitudes of students and teachers towards these are. The experiment with parallel groups was conducted on the population of pupils in the third grade of primary school. The effects of each individual teaching tool was measured, analysed and compared to each other during three separate periods of time. This led to the conclusion: (1) that the modern tools were more effective than the traditional ones, (2) that mind maps have proven to be the most effective, (3) that the traditional teaching tools are still significant, due to their greatest proximity to reality, (4) that the achievement corresponded to the level of positivity of the students' and teachers' attitudes in relation to each individual teaching tool and (5) that no teaching tool can be a complete substitute for the kind of intimacy which is achieved in the immediate interaction between students and teachers.

Kvantifikacija kapaciteta za oporavak nakon naglog pada performansi kod organizacija koje su zavisne od informacionih i komunikacionih tehnologija Aleksić, Aleksandar, 1983- Kapacitet za oporavak organizacija predstavlja relativno novu naučnu oblast i nije detaljno proučena tema imajući na umu njenu kompleksnost i praktičnu primenu. Predmet ove disertacije predstavlja razvoj modela za kvantifikaciju kapaciteta za oporavak kod organizacija koje su zavisne od informacionih i komunikacionih tehnologija (ICT). Motivacija za rad na ovom problemu proistekla je iz činjenice da ne postoji jedinstven model za procenu kapaciteta za oporavak organizacije koji je priznat međunarodnim konsenzusom, već su to deskriptivni modeli koji tretiraju organizacije i koji se kontinualno unapređuju. Naučni cilj rada je kvantifikacija stvarne veličine kapaciteta za oporavak organizacija koje su zavisne od ICT. Imajući u vidu da je reč o modelu za procenu kapaciteta za oporavak, u samoj disertaciji je definisan model organizacije, zatim model kapaciteta za oporavak i na kraju je dat matematički opis istog pomoću teorije fazi skupova koji omogućava da se vrši analiza performansi kapaciteta za oporavak organizacije. Da bi se ostvario naučni cilj rada, primenom savremenih naučnih metoda, determinisana je struktura indikatora kapaciteta organizacije za oporavak, proučen njihov međusobni uticaj sa naglaskom na informacionu i komunikacionu opremu. U cilju detaljne analize modela, izvršeno je poređenje sa postojećim modelima. Оrganizationаl ресилиенце is relatively new scientific field andit is not thoroughly studied through its complexity and practical application. The subject of this dissertation is the development of a model to quantify organizational resilience in organizations that depend on information and communication technology (ICT). The motivation to work on this problem stems from the fact that there is no single model for the assessment of the organizational resilience that is recognized by international consensus, instead of this, there are models that deal with the resilience on the descriptive way which have to be continuously improved. The scientific objective of the dissertation is to quantify the actual size of the organizational resilience in organizations that are dependent on ICT. Bearing in mind that this is a model for the assessment of the organizational resilience, first, the organizational model is defined, then the model of organizational resilience, and in the end, a mathematical description of the model is done by using the theory of fuzzy sets, which enables the analysis of the organizational resilience performance. In order to achieve the science goal of dissertation, the structure of organizational resilience indicators is determined by application of modern scientific methods as well as analysis of their interplay with an emphasis on information and communication equipment. For the purpose of detailed analysis, comparisons with existing models is presented.

Tribološka karakterizacija hibridnih kompozita na bazi legure ZA27 Tribological characterization of hybrid composites based on ZA27 alloy Miloradović, Nenad A., 1968 Tribologija, hibridni kompoziti 62 The subject of research in this doctoral dissertation is testing and improving the tribological properties of hybrid composites based on ZA27 alloy. Composite material is considered to be a mixture of two or more materials or phases of the same material that do not dissolve in each other and which has better properties compared to each of the basic materials. Determination of tribological properties of the developed composites is conducted with variation of the contact geometry, sliding speeds, contact loads and lubrication regimes. Given the increasing importance of hybrid composites, the dissertation is intended to research the development of metal matrix composites by adding different reinforcements to improve their resistance to wear. Particles of silicon-carbide (SiC) and graphite were used as reinforcements. Volume fractions of SiC were 5% and 10%, while graphite volume fractions were 1%, 3% and 5%. Planned laboratory tests were conducted at the Laboratory for tribology of the Faculty of engineering, University of Kragujevac. Analysis of the obtained measurements was conducted and corresponding conclusions were formulated. Qualitative and quantitative analysis of the microstructure of the composites were carried out using SEM and EDS analysis. Possible directions for further research in this area were also given.

Rešavanje nekih problema spektralne teorije grafova Lazić, Mirjana, 1959- Teorija grafova 51 Ova doktorska disertacija pripada Spektralnoj teoriji konačnih i beskonačnih grafova, koja objedinjuje elemente teorije grafova, linearne algebre i opšte spektralne teorije operatora. Teorija grafova, kao posebna matematička disciplina, stara je oko sedam decenija. Razvoj računarske tehnike zahtevao je izgradnju adekvatnog matematičkog aparata tako da je zahvaljujući tome, posredno ili neposredno, teorija grafova doživela svoj intenzivan razvoj, primene u najrazličitijim naučnim disciplinama i veliku popularnost. Pojam grafa se definiše i spada u grupu osnovnih matematičkih pojmova, a figura obrazovana od niza tačaka spojenih krivim linijama je samo geometrijska predstava ili crtež grafa kojim se slikovito predstavljaju razni problemi. Primena teorije grafova i njenih metoda zauzima značajno mesto u teoriji električnih kola, teoriji sistema automatskog upravljanja, teoriji konačnih automata, operacionom istraživanju, računarstvu, teoriji pouzdanog prenosa informacija, u hemiji, ekonomskim naukama, sociologiji, biologiji itd. This doctoral dissertation belongs to the Spectral theory of finite and infinite graphs,which joins elements of Graph theory, Linear algebra and General theory of operators. Graph theory, as special mathematical discipline, is around seven decades old. The developments of the computational techniques asked the construction of suitable mathematical apparatus due to which, directly and indirectly, Graph theory has begun its development intensively, being applied in diferent scientific fields, and very large popularity. The application of Graph theory and its methods take an important role in the theory of electrical circuits, in the theory of systems of automatic control, in the theory of finite automats, operational research, in Informatics, in Chemistry, in Economics, Sociology, Biology etc. Univerzitet u Kragujevcu Prirodno-matematički fakultet Lepović, Mirko, 1958- (ths, code: 07437) Simić, Slobodan, 1948- (oth, code: 00652) Petrović, Miroslav, 1947- (oth, code: 07300) Pavlović, Ljiljana, 1954- (oth, code: 07297) 2009 PhD thesis application/pdf http://eteze.kg.ac.rs/application/showtheses?thesesId=136 https://fedorakg.kg.ac.rs/fedora/get/o:203/bdef:Content/download https://plus.cobiss.net/cobiss/sr/sr/bib/514921109 sr

Jednačine na nekim mrežama Marinković, Silvana, 1960- Algebra, logika 512 Osnove proučavanja Bulovih funkcija i jednačina su postavili Boole, Schröder i Löwenheim u drugoj polovini devetnaestog i početkom dvadesetog veka. Ova oblast se intenzivno razvija u drugoj polovini dvadesetog veka. Taj razvoj se uglavnom odvija u dva osnovna pravca: u pravcu specijalizacije i pravcu generalizacije. Kada se govori o specijalizaciji, misli se na proučavanje pojedinih vrsta Bulovih funkcija i jednačina, kao što su proste Bulove funkcije i jednačine, vrednosne (“swit- ching”) funkcije i jednačine, Bulove diferencijalne jednačine, zatim na proučavanje Bulovih jednačina napojedinim vrstama Bulovihalgebri (relacionealgebre, kompletne Bulove algebre), kao i wihovu primenu u raznim oblastima: u detekciji grešaka u logičkim mrežama, teoriji kodiranja, teoriji automata, teoriji grafova, optimizaciji itd. Kada se govori o generalizaciji misli se na uopštavanje poznatih rezultata o Bulovim jednačinama na jednačine na drugim mrežama, kao što su ograničene distributivne mreže, pseudokomplementarne distributivne mreže, Stonove algebre i dr. Prirodno uopštenje Bulovih jednačina su jednačine na viševrednosnoj logici. Aksiomatizacijom algebre koja odgovara Postovoj viševrednosnoj logici (nazvane Postovomm algebrom) otvara se novo poqe generalizacije -- Postove jednačine. I rezultati Izloženi u ovom radu predstavljaju generalizaciju nekih tvrđenja o Bulovim jednačinama na jednačine na Stonovim algebrama, viševrednosnoj logici i Postovim algebrama This doctoral dissertation belongs to the scienti¯c discipline Algebra and logic. General solutions of an equation are present in various ¯elds of mathematics. Especially, the general solutions were extensively studied in Boolean algebras. In this doctoral dissertation some known results about Boolean equations are generalized to equations on Stone algebras, equations on multiple-valued logic and to equations on Post algebras. The dissertation consists of ¯ve chapters divided in sections, Appendix and Ref- erences. In Introduction some basic notations which will be used in next chapters are given. Because of many theorems from this ¯eld represent generalizations of the cor- responding results for Boolean equations, main results on Boolean functions and equations are exposed in Chapter 2. In Chapter 3, assuming that a general solution is known, the class of reproductive general solutions of the equation f(x1; : : : ; xn) = 0, where L is a Stone algebra and f : Ln ! L is the function with substitution property, is described. All general solutions of equations in one variable on multiple-valued logic are described in Chapter 4. S. Rudeanu in [41] determined the most general form of the subsumptive general solution of a Boolean equation. He also proved that every Boolean transformation was the parametric general solution of a consistent Boolean equation. He stated an open problem: extend this research to Post algebras. Chapter 5 contains some results related this problem. A necessary and su±cient conditions for the existence of a Post function f : Pn ! P (P is a Post algebra) such that the given set of reccurent inequalities be the solution of equation f(x) = 0, are given. We also proved that every Post transformation was the parametric solution of some consistent Post equation.

Neke verovatnosne logike i njihove primene u rtačunarstvu Some probability logics and their applications in computer sciences Ognjanović, Zoran, 1964- matematičla logika, veštačka inteligencija, rezonovanje u prisustvu neizvesnosti 51 Part1. Subjective and objective interpretations of probability are described. The organization of the text is given. Part2. Some propositional probability logics are introduced. Their languages, models, satisfiability relations, and (in)finitary axiomatic systems are given. In this paper the terms finitary and infinitary concern meta language only. Object languages are countable, formulas are finite, while only proofs are allowed to be infinite. Basically, the considered languages are obtained by adding unary probabilistic operators of the form P≥s with the intended meaning “the probability is greater than s”. A Kripke-like possible-world approach to interpret probabilityformulas such that they remain either true or false is proposed. Since the compactness theorem does not hold for some of the considered logics, infinitary axiomatic systems allows proving the corresponding extended completeness theorems. Decidability of the logics is proved using a reduction of the satisfiability problem to the linear programming problem. Part 3. In this part some first order probability logics are considered. In a paper of Abadi and Halpern is proved that there is no recursive axiomatization of these logics, so the presented approach involving infinitary inference rules is the only way to achieve any complete axiomatization. Part 4. New types of probability operators of the form QF, where F is a recursive rational subset of [0, 1] are introduced. A formula QFA is satisfied in a probability model if the measure of the set of worlds that satisfy A is in F. The new operators are suitable for describing events in discrete sample spaces. It is show that the new operators are not definable in languages of probability logics that have been used so far. Part 5. A propositional and a first-order logic for reasoning about discrete linear time and finitely additive probability are given. The languages of these logics allow formulas that say ‘sometime in the future, A holds with probability at least s’. Sound and complete infinitary axiomatizations for the logics are provided. Part 6. In this part a probabilistic extension of modal logic is investigated. It is showed that those logics are closely related, but that modal necessity (denoted by □) is a stronger notion than probability necessity (probability one, P≥1). An example of probability version of Barcan-formula which assures this conclusion is given. Part 7. Decidability of the considered logics is shown by reducing the corresponding satisfiability problem to the linear programming problem. Two automated theorem provers based on that idea are described. Appendix A. This appendix contains the main definitions and formulations of some statements related to probability, Loeb’measure, infinitary logics, and computation complexity. Appendix B. This appendix describes some other approaches in the field: work of Keisler concerning the probabilistic quantifiers, and some other papers about probabilistic operators written by Nilsson, Fagin, Halpern etc. Univerzitet u Kragujevcu Prirodno-matematički fakultet Rašković, Miodrag Mijajlović, Žarko Marković, Zoran Banković, Dragić 1999 PhD thesis application/pdf http://eteze.kg.ac.rs/application/showtheses?thesesId=139 https://fedorakg.kg.ac.rs/fedora/get/o:206/bdef:Content/download https://plus.cobiss.net/cobiss/sr/sr/bib/517319573 sr Autorstvo 3.0 Srbija (CC BY 3.0)

Generalisane kvadraturne formule Gauss-ovog tipa Stanić, Marija, 1975- Kvadraturne formule 51 Ova doktorska disertacija je zapravo deo rezultata, objedinjenih u celinu, do- bijenih tokom višegodišnjeg rada pod mentorstvom profesora Gradimira V. Milo- vanovića. Oblast istraživanja u okviru ove disertacije je razmatranje nekih nes- tandardnih tipova ortogonalnosti i njihova primena na konstrukciju kvadraturnih formula maksimalnog stepena tačnosti. S jedne strane radi se o istraživanjima povezanim sa Teorijom ortogonalnih sistema, što po prirodi pripada Teoriji apro- ksimacija, a sa druge strane konstrukciji kvadraturnih formula za numeričku in- tegraciju funkcija, kao važnom delu Numeričke analize. Moja istraživanja u ovoj oblasti započeta su izradom magistarske teze "Nes- tandardne ortogonalnosti i odgovaraju¶ce kvadrature Gauss-ovog tipa" ([86]), a u okviru projekta "Primenjeni ortogonalni sistemi, konstruktivne aproksimacije i numerički metodi" (Finansiranog od strane Ministarstva nauke i zaštite životne sredine Republike Srbije u periodu 2002{2005). U tom periodu publikovano je nekoliko radova ([65]{[67], [87]), u kojima su objedinjena tri različita pravca istraživanja: ortogonalnost na polukrugu u kompleksnoj ravni u odnosu na ne- hermitski skalarni proizvod, koncept s-ortogonalnosti, kao i koncept višestruke ortogonalnosti. The theory and applications of integration is one of the most important and central themes of mathematics. According to this fact, the subject Numerical Integration is one of the basic in numerical analysis. The problem of numerical integration is open-ended, no finite collection of techniques is likely to cover all possibilities that arise and to which an extra bit of special knowledge may be of great assistance. The field of research in this dissertation is consideration of some nonstandard types of orthogonality and their applications to constructions of quadrature rules with maximal degree of exactness, i.e., quadrature rules of Gaussian type. The research in this dissertation is connected with the following subjects: Theory of Orthogonality, Numerical Integration and Approximation Theory. We have tried to produce a balanced work between theoretical results and numerical algorithms. Gauss's famous method of approximate integration from 1814 can be extended in the several ways. In this dissertation, two ways of possible generalizations are considered. The first, a natural way, is an extension to non-polynomial functions. The second way is a generalization to quadrature rules with multiple nodes. These two generalizations are connected with some systems of trigonometric functions. Also, Gaussian type quadratures for some systems of fast oscillatory functions are considered. Univerzitet u Kragujevcu Prirodno-matematički fakultet Milovanović, Gradimir.

Analiza faktora rizika za nastanak metaboličkog sindroma kod dece i adolescenata Analysis of risk factors for development of the metabolic syndrome in children and adolescents Folić, Nevena D., 1979- Metabolički sindrom Metabolički sindrom Visoka prevalencija metaboličkog sindroma kod dece i adolescenata zabrinjavajući je problem savremenog društva. Cilj istraživanja bio je da se utvrdi korelacija ranije ispitivanih, ali i potencijalno novih faktora rizika za razvoj metaboličkog sindroma kod dece i adolescenata. Sprovedena je klinička opservaciona studija tipa slučaj-kontrola u kojoj su učestvovala deca i adolescenti sa gojaznošću/metaboličkim sindromom, bolnički lečena u periodu od januara 2008. do januara 2012. godine na Klinici za pedijatriju Kliničkog centra Kragujevac. Grupu slučajeva (n=28) činili su pacijenti starosne dobi od 6-18 godina sa dijagnostikovanim metaboličkim sindromom po International Diabetes Federation (IDF) kriterijumima, dok je kontrolnu grupu činilo dvostruko više gojaznih pacijenata (n=56) sličnih karakteristika pacijentima iz komparirane grupe. Utvrđeno je da se signifikantnim faktorima rizika za razvoj metaboličkog sindroma kod gojazne dece i adolescenata mogu smatrati gestacijski dijabetes majke, odnosno izostanak ishrane majčinim mlekom u prvih šest i više meseci života deteta. Takođe, rezultati istraživanja takođe idu u prilog mikroalbuminurije kao značajnog markera ranog dijagnostikovanja metaboličkog sindroma kod gojazne dece i adolescenata. Sagledavanje pomenutih činilaca može poboljšati kvalitet rane identifikacije dece i adolescenta sa rizikom za razvoj metaboličkog sindroma i posebno imati praktični značaj za pedijatre u kreiranju strategije primene preventivnih i pravovremenih korektivnih mera za sprečavanje nastanka pomenutog sindroma odnosno razvoja potencijalnih komplikacija u kasnijem, odraslom životnom dobu. High prevalence of metabolic syndrome in children and adolescents is worrisome problem of modern society. The aim of this research was to determine the correlation of the previously studied and potentially new risk factors for development of the metabolic syndrome in children and adolescents. We performed a case-control clinical study, which was involved children and adolescents with obesity/metabolic syndrome, hospitalized during the period from January 2008 to January 2012 at the Pediatric Clinic of Clinical Center Kragujevac. There were 28 patients, aged 6-18 years, classified as „cases“ who had diagnosed metabolic syndrome according to International Diabetes Federation (IDF) criteria, while the 56 control patients were obese patients, matched to the cases. It was found that gestational diabetes of the mother and artificial nutrition during the first six and more months of the child’s life can be considered as significant risk factors for the development of the metabolic syndrome in obese children and adolescents. In addition, the results of this trial also support the microalbuminuria as an relevant marker of early diagnosis of metabolic syndrome in obese children and adolescents. The consideration of these factors may improve the quality of early identification of children and adolescents who are at risk for metabolic syndrome developing, and especially to have practical importance for pediatricians in creating the strategy of prevention and timely implementation of corrective measures to prevent the occurrence of the aforementioned syndrome and development of potential complications in later, adult life.

Tržišna moć korporacija i konkurencija u grani Kostić, Milan T. 1978- Tržišna moć Konkurencija U savremenim uslovima poslovanja koje karakteriše proces globalizacije tržišna moć korporacija sve više dobija na značaju. Tržišna moć je sposobnost korporacije ili više njih da u dužem roku na nekom tržištu profitabilno odrede cenu iznad graničnih troškova, odnosno konkurentne cene. Tako definisana tržišna moć utiče na konkurentske uslove poslovanja i zavisi od niza faktora među kojima se izdvaja relevantno tržište kao mesto gde se ova moć ispoljava. Pored dimenzija relevantnog tržišta, koje u sebi sadrži proizvodnu i geografsku komponentu, na veličinu tržišne moći a posledično i na uslove konkurencije u grani utiču i drugi faktori među kojima izdvajamo: ulazne barije, životni ciklus grane i horizontalna i vertikalna povezivanja korporacija. Tržišna moć i stepen ograničenosti tržišta se može izmeriti korišćenjem niza pokazatelja koncentracije i nejednakosti od kojih se pojedini često primenjuju u antimonopolskoj regulativi razvijenih zemlja (npr. Racio koncentracije i Herfindal-Hiršmanov indeks). Pokazatelji koncentracije i nejednakosti predstavljaju kvalitetnu osnovu za primenu odgovarajućih mera poboljšanja uslova konkurencije. Proizilazi da su referentne vrednosti ovih pokazatelja dobar instrument za analizu uslova konkurencije i primenu mera za njeno poboljšanje. In contemporary business environment, characterized by globalization, the market power of corporations is increasingly gaining in importance. Market power is the ability of a corporation or more of them to profitably set the price above marginal cost, i.e. competitive pricing, in a market in the long run. Thus defined market power affects the competitive business conditions and depends on many factors, among them the relevant market as a place where this power is manifested. Besides the size of the relevant market, which encompasses production and geographical component, the size of market power and consequently the conditions of competition in the industry are influenced by other factors, among which we highlight: barriers to entry, industry evolution, and horizontal and vertical integration of corporations. Market power and the degree of market limitation can be measured using a variety of indicators of concentration and inequality of which some are often used in anti-monopoly regulation of developed countries (e.g. concentration ratio and the Herfindahl-Hirschman Index). Indicators of concentration and inequality provide an adequate basis for the implementation of appropriate measures for improving the conditions of competition. It follows that the reference values of these indicators are a good instrument for analysing the conditions of competition and implementing measures for its improvement.

Razvoj organizacionih kapaciteta za podsticanje preduzetničkog ponašanja Erić, Jelena M. 1977- Menadžment Korporativno preduzetništvo Korporativno preduzetništvo predstavlja sistematsku preduzetničku inicijativu koja revitalizuje organizaciju iznutra i oblikuje poslovanje putem prepoznavanja i eksploatacije identifikovanih preduzetničkih prilika. Ono obuhvata kreiranje novih poslova u okviru postojećeg, kao i transformaciju ili revitalizaciju organizacije kroz redefinisanje ključnih vrednosti na kojima je zasnovana. Imajući u vidu da je korporativno preduzetništvo sredstvo za dostizanje i održanje konkurentske prednosti u dužem roku, značajno je identifikovati i analizirati organizacione faktore koji doprinose podizanju organizacionih kapaciteta za podsticanje preduzetničkog ponašanja. Corporate entrepreneurship represents systematic entrepreneurial initiative aiming to revitalize the organization internally and shape the business through the identification and exploitation of identified entrepreneurial opportunities. It refers to the creation of new business within the existing one, but also the transformation and revitalization of the organization through a redefinition of its core values. Bearing in mind that the corporate entrepreneurship is a mean for achieving and sustaining competitive advantage in the long run, it is important to identify and analyze organizational factors that influence organizational capacity to encourage employees’ entrepreneurial behavior.

Model regionalne konkurentnosti: teorijsko-metodološka analiza i mogućnosti primene u Srbiji Model of regional compeveness: theorecal-methodological analysis and possibilies of applicaon in Serbia Vuković, Darko, 1978- Regionalna konkurentnost Konkurencija Niska konkurentnost srpske privrede i odsustvo regionalne politike, stvorile su potrebu za kreiranjem modela regionalne konkurentnosti, koji će identifikovati, selektovati i analizirati ključne faktore konkurentnosti regiona u Srbiji. U ovoj doktorskoj disertaciji, kreiran je Model pahulje regionalne konkurentnosti, koji osim ekonomskih i socijalnih faktora, analizira i faktore: inovacija, infrastrukture, ljudskog kapitala, neformalnih institucija i zaštite svojine, kulture i turizma, kao i geo-prirodne faktore. Model uključuje i kompozitni indeks (IRK) koji meri i rangira 78 indikatora i pod-indikatora. Na osnovu rezultata merenja indikatora i faktora regionalne konkurentnosti, kreiraju se „pahulje konkurentnosti“, koje na slikovit način prikazuju konkurentsku snagu svakog regiona. Imajući u vidu broj merenih faktora i indikatora, kvantitativnu osnovu modela i osobinu grafičkog prikaza, Model pahulje spada u više-problemske ili kompleksne modele regionalne konkurentnosti. Low competitiveness of the Serbian economy and the lack of regional policies have created the need for designing a model of regional competitiveness, which will identify, select and analyze the key factors of regional competitiveness in Serbia. In this PhD thesis, a Snow flake model of regional competitiveness has been created analyzing, beside economic and social factors, other factors such as: innovation, infrastructure, human capital, informal institutions and the protection of property rights, culture and tourism, as well as geo-natural factors. The model includes a composite index (IRC) which measures and ranks 78 indicators and sub-indicators. Based on the measurement results of indicators and factors of regional competitiveness, the snowflakes of competitiveness have been created presenting the competitive strength of each region in a picturesque manner. Considering the number of measured factors and indicators as well as the quantitative base of model with the aim of graphical representation, Snowflakes model belongs to the multi-problem or complex models of regional competitiveness. It can be used as a means of socio-economic analysis of regional competitiveness, because it determines the strengths and limitations at regional level. A correlation analysis of indicators of regional competitiveness has been included with the aim to demonstrate their mutual interdependence.

Efekti hiperbarične oksigenacije na protetičku rehabilitaciju bolesnika sa jednostranom amputacijom donjeg ekstremiteta Effects of hyperbaric oxygenation on prosthetic rehabilitation of patients with unilateral lower limb amputation Simanić, Igor, 1971- Ektremiteti Objective. Hyperbaric oxygen (HBO) has been widely used in people with diseases that cause limb amputation but studies that target patients who underwent amputation itself are rare. The aim of our study was to investigate the effects of HBO on prosthetic rehabilitation in patients with unilateral lower limb amputation. Methods. The study included 60 patients with unilateral (left or right side) lower limb amputation, mean age 61.6 ± 11.5 years, of both genders. They were divided into two groups, the experimental group (with HBO) and the control group (usual care). Patients’ functional skills after amputation were evaluated using the LCI test (Locomotor Capabilities Index) and with the classification of Narang and Pohjolainen. Results. Clinical characteristics of patients had relatively homogeneous distribution. After the therapy, a control measurement of both groups showed significantly higher values for LCI test (p <0.01) and lower values for Narang score (p <0.01). However, improvements were more prominent in the group of patients who underwent HBO therapy, therefore, these subjects in the control measurements were evaluated with a statistically significant lower Narang score (p <0.05) and had higher LCI score than the control group patients. Conclusion. HBO is a useful therapeutic measure in the rehabilitation of people with limb amputation who use prosthetic limbs. Cilj. Hiperbarična oksigenacija (HBO) se široko koristi kod osoba sa oboljenjima koja uzrokuju amputacije ekstremiteta, ali su ciljane studije kod bolesnika posle same amputacije raritetne. Cilj naše studije je bio da se ispitaju efekti HBO na protetičku rehabilitaciju kod bolesnika sa jednostranom amputacijom donjeg ekstremiteta. Metode. U studiju je bilo uključeno 60 pacijenata sa jednostranom (leva/desna strana) amputacijom donjeg ekstremiteta, prosečne starosti 61,6 ± 11,5 godina, oba pola. Oni su podeljeni u dve grupe, eksperimentalnu kojoj je primenjena HBO i kontrolnu grupu. Ispitanici su podvrgnuti procenjivanju funkcionalne osposobljenosti amputiranog patrljka upotrebom LCI testa (Indeks lokomotornih sposobnosti) i pomoću klasifikacije Naranga i Pohjolainena. Rezultati. Kliničke karakteristike bolesnika u grupama relativno su homogeno distribuirane. Nakon perioda protetičke rehabilitacije obe grupe ispitanika su na kontrolnom merenju imale statistički značajno više vrednosti LCI testa (p < 0,01) i niže vrednosti Narang skora (p < 0,01). Međutim, nastala poboljšanja su bila izraženija u grupi ispitanika koji su bili podvrgnuti HBO terapiji, tako da su ovi ispitanici na kontrolnom merenju bili ocenjeni sa statistički značajno nižim Narang skorom (p < 0,05) odnosno imali su viši LCI skor od kontrolne grupe ispitanika. Zaključak. HBO je korisna terapijska mera u rehabilitaciji osoba sa amputacijom ekstremiteta koje upotrebljavaju protetička sredstva Univerzitet u Kragujevcu Fakultet medicinskih nauka Jakovljević, Vladimir, 1971- Rosić, Gvozden, 1964- Parezanović-Ilić, Katarina, 1965- Milanović, Miroslav 2013 PhD thesis application/pdf http://eteze.kg.ac.rs/application/showtheses?thesesId=307 https://fedorakg.kg.ac.rs/fedora/get/o:220/bdef:Content/download https://plus.cobiss.net/cobiss/sr/sr/bib/519431061 sr Autorstvo-Nekomercijalno-Deliti pod istim uslovima 3.0 Srbija (CC BY-NC-SA 3.0)

Korelacija bioloških aktivnosti sintetisanih derivata 4-hidroksikumarina i njihovih fizičko-hemijskih parametara Mladenović, Milan, 1984- Kumarin Hidroksikumarin Serija od sedamnaest derivata 4-hidroksikumarina, supstituisanih u položaju 3 polarnim funkcionalnim grupama, testirani su kao antimikrobni, antioksidativni i antikoagulativni agensi. Antimikrobna aktivnost testiranih derivata 1-10s određena je dilucionom metodom u in vitro uslovima pri čemu su derivati pokazali umerenu aktivnost. Antioksidativna aktivnost in vitro derivata 1-10s određena je konstatovanjem totalnog antioksidativnog kapaciteta, sposobnosti neutralizacije DPPH, peroksidnog i hidroksi radikala i helatizacionog kapaciteta testiranih agenasa, pri čemu su svi derivati pokazali izrazitu antioksidativnu aktivnost. Antikoagulativna aktivnost in vivo derivata 1-10s ispitivana je nakon intraperitonealne aplikacije derivata na laboratorijskim pacovima Wistar soja i merenjem protrombinskog vremena. Derivati 1-10s pokazali su odličnu antikoagulativnu aktivnost nakon višednevne aplikacije, nisu izazvali inflamaciju niti promene na jetri životinja. The series of seventeen 4-hydroxycoumarin derivatives, substituted at C-3 position with high polar scaffolds, were evaluated as antimicrobial, antioxidant and anticoagulant agents. The in vitro antimicrobial activity of compounds 1-10с was determined using the dilution method. During the evaluation of antimicrobial activity, coumarin derivatives showed moderate potential. The compounds 1-10с antioxidant activity in vitro was determined using Total antioxidant capacity assay, DPPH radical scavenging assay, Lipid peroxidation in linoleic acid emulsion inhibition assay, Hydroxyl radical scavenging activity assay and Ferrous ion chelating ability assay. During the evaluation of antioxidant activity, coumarin derivatives presented excellent activity. The anticoagulant activity in vivo was evaluated after the continuous intraperitoneal administration of compounds 1-10с to adult Albino Wistar rats and by measuring the prothrombin time. Administrated compounds presented excellent anticoagulant activity and induced no inflammation or change to the animal liver.

Činioci nastanka anemije u dece The factors of anemia in children Crnčević-Radović, Ljiljana M., 1964- Anemija, prediktor, školska deca, Srbija predikator Doktorska disertacija predstavlja prvu studiju kojom je procenjen značaj problema anemije u dece uzrasta 7-14 godina u Srbiji, utvrđena povezanost anemije sa činiocima koje literatura opisuje kao njene prediktore i čijim Predlogom strategije za prevenciju i kontrolu anemija se predlaže najadekvatnija tehnologija njenog rešavanja u našim uslovima. Primenjen je dizajn studije preseka, na reprezentativnom uzorku po polu, uzrastu i mestu življenja dece i omladine Srbije kao celine i Centralne Srbije, Vojvodine, Beograda, seoskih i gradskih područja. Uzorak istraživanja čini 527 dece uzrasta 7-14 godina, kojima je u kapilarnoj krvi Drabkinovom metodom, u okviru jedinog populacionog istraživanja zdravlja koje se bavilo problemom anemije u nas, projekta ,,Zdravstveno stanje, zdravstvene potrebe i korišćenje zdravstvene zaštite stanovništva Srbije“ sprovedenog 2000. godine određivana vrednost hemoglobina. Pored antropometrijskih i biohemijskih merenja, izvor podataka čini i Upitnik za decu i omladinu uzrasta od 7 do 19 godina. Dobijeni rezultati su prikazani i analizirani adekvatnim statističkim metodama. Najznačajniji rezultati istraživanja su da je anemično 17,8% dece ispitivanog uzrasta, da anemije najviše ugrožavaju dečake uzrasta 12-14 godina, decu lošijeg materijalnog statusa, lošijeg uspeha u školi, nestruktuiranog slobodnog vremena, doseljene, stanovnike kolektivnih centara, ruralnih i visoko urbanih sredina, da je anemija ređa pri pravilnoj ishrani, anemični su bolesniji i lošije funkcionišu, zdravstvena zaštita je glavni ,,stručni krivac“ za postojanje anemije u ovoj meri i da je potrebno rešavati planiranjem za zdravlje, na nacionalnom nivou, strateškim, institucionalnim i strukturalnim planiranjem, usmerenim na promene u populaciji kao celini i u delovima sa visokim rizikom. Doctoral dissertation presents the first that evaluates the significance of anemia in children aged 7-14 years in Serbia, which confirms association between anemia and its predictors described in the literature, recommending the strategy for the prevention and control of anemia and suggesting the most adequate technology of its solution under the conditions in Serbia. A cross-sectional study design was used on a representative sample (according to gender, age and place of residence) of children and youth in Serbia. The study sample was composed of 527 children in whom hemoglobin from capillary blood was determined by Drabkin, s method conducted within a population health research on the problem of anemia in Serbia, as a part of the project “Health status, health needs and the use of health services in Serbia“ from 2000. Beside anthropometric and biochemical measurements, the source of data was the Questionnaire for children and youth aged 7-19 years. The obtained results are presented and analyzed using adequate statistical methods. The most significant study results are the following: 17.8% children of the studied age are anemic; anemia most often endangers boys aged 12-14 years, children of poorer financial status, lower achievement in school, unstructured free time, immigrants, inhabitants of collective centers, rural and highly urbanized environment; anemia is rarer with proper nutrition, anemic patients have more problems with health and functioning; healthcare is the main “expert culprit” for the presence of the problem to this extent and it should be solved at the national level.

Logike sa integralima u uslovnim očekivanjima Ristić, Vladimir T. 1974- Matematička logika It could say that the research of logical systems in the dissertation goes in two directions: the first one is related to probability theory i.e. measure theory, while the other direction is related to topology. The main subject of this dissertation is extending the classical logic to formal systems which will be adequate for describing and concluding in the mentioned mathematical environments. The first part represents follow-up of works by M. Rašković and R. Đorđević in the area of probability logics and especially in the area of biprobability logics. The focus is on the logics with integral operators and logics with conditional expectation operators. The topological class logic [11, 12], which is adequate for studying the notions of topological product and continuous functions on topological class-spaces, is presented in the second part of this dissertation.

Evaluacija efekata različitih režima ishrane na morfofunkcionalne karakteristike i fizičkom aktivnošću indukovane markere oksidativnog stresa i inflamatornog odgovora kod mladih sportista Evaluation of the effects of different diets on the morphophynctional characteristics induced by physical activity and markers of oxidative stress and inflammatory response in young athletes Nešić, Miroslav, 1960- inflamacija, oksidativni stres, fizička aktivnost, aerobni kapacitet, telesni sastav inflamacija Cilj ove studije je bio da ispita efekat različitih režima ishrane u smislu različitog udela polinezasićenih masnih kiselina (n-3 i n-6 PUFA (Polyunsaturated Fatty Acids)) u ishrani na vrednosti morfoloških i funkcionalnih parametara, kao i proinflamatornih medijatora i nivo oksidativnog stresa, u miru i nakon maksimalnog testa opterećenja pre i nakon dvomesečnog trenažnog programa. Metode. U studiji je učestvovalo 75 mladih fudbalera omladinske fudbalske škole `Kragujevac`, starosti od 18 - 19 godina. Svi ispitanici imali su sportski staž od minimalno 5 godina, sa 12 sati treninga nedeljno. Oni su bili podeljeni u tri grupe: dve eksperimentalne i kontrolnu grupu. Svi ispitanicim su bili podvrgnuti standardnom sportsko-medicinskom pregledu, a potom i određivanju nivoa proinflamatornih medijatora i nivoa oksidativnog stresa, u miru i nakon maksimalnog testa opterećenja pre i nakon dvomesečnog trenažnog programa. Rezultati. Dodatak ribljeg i suncokretovog ulja je bio povezan sa povećanjem aerobne moći ispitivanih fudbalera, i može biti vrlo korisna kako u redukciji oksidacionog stresa, tako i u podizanju aktivnosti antioksidacionog enzimskog sistema naših ispitanika. Tokom fizičkog opterećenja suplementacija različitim vrstama PUFA nije imala značajni uticaj na markere oksidacionog stresa. Takođe, upotreba različitih vrsta PUFA nije bitnije uticala na proizvodnju citokina neposredno nakon akutnog nastupa sportske aktivnosti (testa opterećenja). Zaključak. Režim ishrane koji podrazumeva dodatak ribljeg i suncokretovog ulja u kombinaciji sa stručno vođenim i pažljivo planiranim trenažnim procesom pozitivno utiče na povećanje funkcionalnih karakteristika i inflamatorno-oksidacionog odgovora ispitivanih fudbalera, što je izuzetno važno u podizanju nivoa njihove fizičke spreme i postizanju vrhunskih sportiskih performansi. Ovaj nalaz može biti koristan u proceni kvaliteta treninga, koji je kod adolescenata od krucijalnog značaja za pravilan psiho-fizički razvoj i dalju karijeru. The aim of this study was to assess the effect of different diets in terms of various proportions of polyunsaturated fatty acids (n-3and n-6 PUFA) in the diet, on the morphological and phynctional parameters, as well as pro-inflammatory and mediators of oxidative stress, at rest and after maximal exercise test before and after a two-month training program. Methods. The study included 75 young players of the youth soccer school `Kragujevac`, aged 18 - 19 years. All subjects had sports experience of minimum 5 years, with 12 hoursof training per week. They were divided into three groups: two experimental and the control group. All subjects underwent a standard sport-medical examination and then determination of the level of proinflammatory mediators and the level of oxidative stress markers at rest and after a maximal exercise test before and after a two-month training program. Results. Suplementation of fish and sunflower oil was associated with an increase in aerobic power of the tested players, and can be very useful in the reduction of oxidative stress, as well as raising in activity of antioxidant enzymatic system of our subjects. During exercise testing different types of PUFA supplementation had no significant effect on oxidative stress markers. Also, the use of different types of PUFA did not significantly affect the production of cytokines immediately after acute performance sports activities (exercise test). Conclusion. Diet supplement that includes fish and sunflower oil, combined with expert guided and carefully planned training process has a positive effect on increasing the phynctional characteristics and oxidativeinflammatory response of tested players, which is extremely important in raising the level of their physical fitness and achieving top sport performance. This finding may be useful in assessing the quality of training, which in adolescents is crucial for proper mental and physical development and further career.

Statistička teorija uzročnosti u neprekidnom slučaju Dimitrijević, Slađana, 1975- Teorija verovatnoće Finding the cause or determining what is the cause and what is the consequence are probably one of the eldest problems of science. Philosophy from the beginning deals with these issues in the most general way, but other sciences also try to solve this kind of problems within their object of interest. Based on the results of Probability theory, Theory of random processes and Statistics, Statistical theory of causality originated as one of mathematical answers to the problem of determining causality in an arbitrary system. After the seminal papers of Granger (1969) and Sims (1972) many authors considered different types of stochastically defined causality. These researches mainly belong to predicting theory. Namely, the question of interest is: whether we can predict with the same accuracy in case of reduction of available information. At first, the researches were focused on discrete time stochastic processes (time series). However, as it is pointed out, there is a need for defining causality for continuous time stochastic processes, because many processes of interest have continuous time parameter. Namely, for financial time series is explained that even though the agents have only perceptions in discrete time, the underlying stochastic process of interest is in continuous time. Thus, the development of continuous time modeling in finance is important motivation for considering causality in continuous time. Also, the observed causality in a discrete time model may depend on the length of interval between each two successive samplings. Mykland (1986) and Florens and Fougères (1996) were the authors of first papers in which we can find definitions of causality in continuous time, given in terms of σ-algebras, i.e. natural filtrations of stochastic processes. Also, in Gill and Petrović (1987) and in Petrović (1996) definition of causality was given in continuous time, but in term of Hilbert spaces, i.e. L2-framework. Recently, there have been several papers which deal with these themes. The field of research in this dissertation is consideration of some causality concepts that are generalizations of Granger causality adopted for stochastic processes with continuous time. Also, same relationships of developed concept of causality and already existed related theories (adopted distributions) are considered. This dissertation, beside Preface and References with 86 items, consists of four chapters 1. Theory of random processes - basic notions; 2. Theory of causality - review of known results; 3. Generalization of Granger causality for stochastic processes with continuous time; 4. Causality and adopted distribution of stochastic processes. Chapter 1 is a brief overview of notions of theory of probability and stochastic processes that will be use later. Some known concepts of causality, both in discrete and in continuous case, are presented in Chapter 2. We followed the chronological development of the Statistical theory of causality, and special attention is given to the concepts that have contributed to our researches. Chapter 3 presents some generalizations of Granger causality adopted for stochastic processes with continuous time. Our original results, related to properties of developed concepts of causality, are given there. Specially we focused our attention to integration of stoping times into considered concept of causality, to invariance of causality under convergence and to relationship between causality and markovianity. Finally, in Chapter 4, we give connections between considered concept of causality and concept of adapted distribution of stochastic processes (specific concept of equivalence of stochastic processes), which introduced mathematicians from Model theory, Kiesler and Hoover Univerzitet u Kragujevcu Prirodno-matematički fakultet Petrović, Ljiljana, 1956- Janković, Svetlana, 1949- Bojović, Dejan, 1968- 2013 PhD thesis application/pdf http://eteze.kg.ac.rs/application/showtheses?thesesId=329 https://fedorakg.kg.ac.rs/fedora/get/o:232/bdef:Content/download https://plus.cobiss.net/cobiss/sr/sr/bib/519455893 sr Autorstvo-Nekomercijalno 3.0 Srbija (CC BY-NC 3.0)

Analiza citohistoloških faktora koji doprinose pojavi nepravilnih krvarenja, bola i febrilnosti kod pacijenatkinja sa miomima uterusa Mladenović-Mihailović, Aleksandra, 1958- Miomi uterusa citohistološke karakteristike Rezultati naše studije pokazali su da nije uočena statistički značajna razlika u histološkom tipu mioma između ispitanica sa iregularnim krvarenjem i ispitanica bez simptoma i sa bolom i inflamacijom. Ovakav rezultat sugeriše da histološki tip mioma ne utiče na kliničku sliku pacijentkinje. U obe analizirane grupe u ovoj studiji najzastupljenije su bile ispitanice sa miomima celularnog tipa i miomima neurolinoma-like tipa. Statistički značajna razlika nije uočena ni u ekspresiji α- glatkomišićnog aktina između ispitanica sa iregularnim krvarenjima i kontrolne grupe ispitanica. I u grupi sa iregularni krvarenjima i u grupi sa bolom i inflamacijom i asimptomatskim miomima, najmanje ispitanica imalo je ekspresiju α- glatkomišićnog aktina manju od 35% (+), a najviše je bilo ispitanica sa ekspresijom do 100% (+++). Ovakav rezultat sugeriše da dominantu ćelijsku populaciju u tkivu mioma, bez obzira histološki tip, čine glatke mišićne ćelije različitog fenotipskog statusa, među kojima dominiraju glatke mišićne ćelije kontraktilnog fenotipa, uz prisutan jedan broj glatkih miocita sintetskog fenotipa organizovan u vidu ostrvaca između njih. Između analiziranih grupa nije uočena statistički značajna razlika ni u ekspresiji CD34. U obe grupe najviše je bilo ispitanica sa ekspresijom CD34 opisanom sa dva (do 35%) i jednim (do 75%) plusom a najmanje sa ekspresijom opisanom sa tri plusa. Kako je CD34 antigen koji se između ostalog eksprimira na površini tkivnih fibroblasta, ovakav rezultat sugeriše da bez obzira na histološki tip mioma tkivni fibroblasti čine manju ćelijsku populaciju u tkivu u odnosu na populaciju glatkih mišićnih ćelija.

Ispitivanje uloge i značaj STAT3 molekula i humanih mezenhimalnih matičnih ćelija u eksperimentalnom modelu tumora dojke The role and significance of STAT3 molecule and human mesenchymal stem cells in experimental model of mammary carcinoma Ljujić, Biljana T., 1974- hMSC STATS3 Humane mezenhimalne matične ćelije (hMSC) mogu da migriraju u tumor, integrišu se u stromu i promovišu njegov rast. Uticaj hMSC na rast tumora kao i njihova uloga u imunologiji tumora još uvek je kontroverzna i nedovonjno rasvetljena. Stoga je u ovom radu ispitivan uticaj hMSC na pojavu, rast i metastaziranje tumora i antitumorski imuniski odgovor u eksperimentalnom modelu tumora dojke. Rezultati ove studije pokazuju da sistemska aplikacija hMSC u BALB/c miševe kojima su transplantirane 4T1 tumorske ćelije, promoviše rast i metastaziranje tumora dojke. Ovi tumor promovišući efekti hMSC nisu posledica aktivacije STAT3 puta u tumorskom tkivu. Detektovana promocija rasta i metastaziranja tumora udružena je sa smanjenom citotoksičnom aktivnošću splenocita, NK i CD8+ T ćelija in vitro. Oboleli miševi kojima su aplikovane hMSC imali su značajno niži procenat CD3+NKp46+ NKT-like ćelija i značajno viši procenat CD4+Foxp3+ T ćelija, uz istovremeno povećen nivo Th2 i smanjen nivo Th1 citokina u serumu. Takođe, značajno više CD4+ IL-10+ T limfocita detektovano je u istoj grupi miševa. Naši rezultati pokazuju da progresija i metastaziranje tumora dojke u grupi miševa tretiranih hMSC korespondira u najvećoj meri sa povišenim nivoom Th2 citokina i povećanim procentom CD4+Foxp3+T ćelija. Human mesenchymal stem cells (hMSC) can home to tumor sites, integrate into tumorassociated stroma and promote tumor growth. The effects of hMSC on tumor growth are controversial and involvement of hMSC in tumor immunology has not been adequately addressed. Therefore, we investigated whether injection of hMSC affects tumor appearance, growth and metastasis, and anti-tumor immunity in an experimental animal model of metastatic breast cancer. Injection of hMSC in BALB/c mice bearing mammary carcinoma promoted tumor growth and metastasis. This promotion of tumor growth is not consequence of activation of STAT3 molecules in the tumor tissue. The promotion of tumor growth and metastasis was accompanied by lower cytotoxic activity of splenocytes, NK cells and CD8+ T cells in vitro. Tumor-bearing mice that received hMSC had significantly lower percentages of CD3+NKp46+NKT-like but significantly higher percentages of CD4+Foxp3+ T cells. Increased serum levels of Th2 and decreased serum levels of Th1 cytokines were associated with injection of hMSC in tumor-bearing animals. Also, a significantly higher number of CD4+ cells expressing IL-10 were found in tumor-bearing animals that received hMSC compared with other recipients. These results demonstrate that promoted breast cancer progression and metastasis in mice treated with hMSC corresponds mainly to increased systemic Th2 cytokines, and enhanced percentage of CD4+Foxp3+T cells.

Evaluacija kvaliteta života kod bolesnika sa epilepsijom i bolesnika sa psihogenim neepileptičkim napadima Evaluation of the quality of life of patients with epilepsy and patients with physchogenic non-epileptic seizures Škrijelj, Fadil, 1958- psihogeni neepileptički napadi, odrasli, kvalitet života Mnoge hronične bolesti, a posebno epilepsija, značajno remete i umanjuju kvalitet života obolelog, kako u smislu osećaja opšteg zdravstvenog blagostanja, tako i svakodnevnih životnih aktivnosti. Epilepsija kompromituje bolesnikov život u zdravstvenoj, psihosocijalnoj i profesionalnoj sferi. Zato je cilj savre-mene epileptologije da pored uspostavljanja potpune kontrole epileptičkih napa-da, postigne i što bolji kvalitet života obolelog. Kvalitet života povezan sa zdravljem odslikava uticaj bolesti na život bolesnika, odnosno meru patnje koja je uslovljena bolešću i njenim pratećim smetnjama. Time je procena kvaliteta života postala sastavni deo protokola lečenja obolelih od epilepsije, odnosno hroničnih bolesti. Introduction: Many chronic diseases, particularly epilepsy, considerably impair and decre-ase the patients’ quality of life, both in regard to general well-being and everyday life acti-vities. Epilepsy compromises the patient’s life within medical, psychosocial and professio-nal spheres. Therefore, besides sustaining a full control over epileptic seizures, the goal of modern epileptology is to achieve the best possible quality of life of the patient. The qua-lity of life related to health reflects the influence of disease on the patient’s life, i.e. the me-asure of suffering caused by the disease and its associated disorders. Thus, the evaluation of the quality of life has become the inevitable part of treatment protocol in patients with epilepsy, i.e. chronic diseases.

Efekti medikamentozne terapije na troškove i kvalitet života kod pacijenata sa psorijazom vulgaris Jevtić-Milić, Tatjana, 1974- Psoriasis vulgaris, kvalitet života Psoriasis vulgaris, quality of life, costs Studija je dizajnirana kao retrospektivno kohorta studija, sa dve grupe: pacijenti sa psorijazom koji su imali celokupni režim lečenja i pacijenti sa psorijazom koji nisu bili istrajni u propisanom režimu lečenja. Poštovanje režima lečenja je od suštinskog značaja za uspešno lečenje psorijaze, a što može značajno poboljšati rezultate negepacijenata, uključujući i smanjenje ukupnih troškova lečenja. Cilj ovog istraživanja je bio da se uporede klinički i troškovni ishodi kod ne-biološke terapije psorijaze. Pridržavanje propisanih režima mereno je na kraju perioda praćenja, kroz odnos između broja dnevnih zaliha lekova u toku jedne godine i broja dana u godini. Pacijenti su imali prepisani terapiski tretman koji odgovara njihovom kliničkom statusu, a prema važećim međunarodnim vodičima za psoriazu, za period od jedne godine, kroz četiri posete sa intervalima od tri meseca. Pacijenti kod kojih je taj odnos bio manji od 80% su svrstani u grupu neredovne terapije. Studija obuhvata 108 pacijenata, 61 njih (56,5%), su se pridržavali propisanog tretmana, a 47 (43,5%) nisu bili istrajni u poštovanju propisanog režima lečenja. Značajan pad PASI skora tokom studijskog perioda zabeležen je u pacijenata koji su istrajni u propisanoj terapiji (Hi-kvadrat = 61.085; df = 3, p <0.001). Troškovi su takođe značajno smanjeni u grupi pacijenata koji su istrajni (Hi-kvadrat = 17.432; df = 3, p = 0.001), Najveći pad je bio troškova kod posete 3. Smanjenje PASI skora i troškova je kod neistrajnih pacijenta u daleko manjem procentu. Pridržavanje i poštovanje propisanih režima lečenja dovodi do bržeg kliničkog poboljšanja i smanjenja troškova lečenja, a što umanjuje ukupnu potrošnju zdravstvenog sistema i društva. Ulaganjem u dodatna istraživanja psorijaze omogućiće efikasnije lečenje i ostvariti značajne uštede kako u zdravstvu tako i u privredi jer se smanjuje absentizam, a povećava produktivnost. The study was designed as a retrospective cohort study, with two groups: the patients with psoriasis adherent to the prescribed treatment regimen, and the patients with psoriasis non-adherent to the prescribed treatment regimen. The patients were prescribed a treatment regimen appropriate to their clinical status, according to current international guidances for psoriasis, and then followed for a period of one year, through four visits with intervals of three months. Results. The study enrolled 108 patients, 61 of them (56,5%) being adherent to the prescribed treatment, and 47 (43,5%) were non-adherent. Significant decrease of PASI score throughout the study period was noted in the patients adherent to prescribed therapy (Chi-square = 61,085; df=3; p<0,001). The costs also decreased significantly in the group of adherent patients (Chi-square = 17,432; df = 3; p = 0,001), and the drop of costs was the highest from the visit 3. The decrease in PASI score and costs was less rapid in non-adherent patients. Conclusion. Better treatment adherence leads to faster clinical improvement and more rapid decrease in costs of treatment, which diminish overall expenditure of the health system and society, leaving room for treating other diseases more efficiently. Therefore, health systems of developing countries should support additional research of causes of treatment non-adherence in patients with psoriasis, in order to minimize this fenomenon more efficiently, and make significant savings.

Neki rezultati o ekstremnim vrednostima Randićevog indeksa na grafovima Divnić, Tomica, 1969- This doctoral dissertation belongs to the Combinatorial Optimization applied to graphs, which includes elements of Linear and Quadratic Programming and Graph Theory. Combinatorial Optimization, as special mathematical discipline, is relatively young, although the first papers are more than two hundred years old. The fast development emerges after the second wold war, when grows need for optimization many tasks and processes. Since many objects could be represents as graph and combinatorial optimization solve extremal problems on discrete structures, there is narrow connection with Graph Theory. The subject of this dissertation is finding minimal value of the Randi´c index on n-vertex graphs G(k, n) with given minimum degree k of vertices and describing the structure of extremal graphs. This index was introduced 1975 by chemist Milan Randi´c in order to measure the branching of some molecules. There is a good correlations between this index and some physico-chemical properties of alcanes. There is, also, connection between Randi´c index and the eigenvalues of the Laplacian matrix of graph.

Strukturne i elektronske osobine kompleksa nikal(II) sa pentadentatnim diaminotrikarboksilatnim ligandima Belošević, Svetlana K., 1970- Helatori su grupa hemijskih jedinjenja koja poseduju dva ili više donorskih atoma. Imaju jedinstvenu osobinu helatacije (multikoordinacije metalnog jona) metalnih jona i atoma. EDTA (etilendiamin-tetrasirćetna kiselina) i njegovi analozi nalaze značajnu primenu kako u detoksifikaciji određenih matrica životne sredine (vode pre svega) zagađenih jonima metala tako i u nuklearnoj medicini za proizvodnju određenih kontrasta pri skeniranju tkiva magnetnom rezonancom. Polazeći od ovih činjenica mi smo za predmet ove disertacije predvideli sintezu nekih nedostajućih kompleksa nikla(II) kako bi smo kompletirali seriju jednostavnih diaminopolikarboksilnih helatnih kompleksa. Metodom rendgenostrukturne analize kao i analizom sintetisanih molekula na bazi savremene kompjuterske hemije sintetisana jedinjenja su sistematski karakterisana. Osnovni cilj bio je da se ispitaju uzročno-posledične veze broja i distribucije petočlanih i šestočlanih helatnih prstenova u kompleksnom molekulu, njihove distribucije u kompleksu, stereohemije i elektronske konfiguracije. U ovoj disertaciji je sintetisano i karakterisano nekoliko različitih tipova helata kao što su: pentadentati diaminotrikarboksilatnog tipa (H3ed3a, H3ed3r, H3eda2r, H31,3-pd3a, H31,2-pd3a i H31,2-pd2ar); heksadentati diaminotetrakarboksilatnog tipa (H41,3-pd3ap). Nagrađeni helati su iskorišćeni za sintezu odgovarajućih kompleksa nikla(II). Na bazi rezultata rendgenske strukturne analize utvrđeno je da su najstabilniji heksadentatni helati oni sa ravnomernim brojem petočlanih i šestočlanih helatnih prstenova. Korelacioni dijagram oktaedarskih devijacija uglova oko metalnog jona i tetraedarskih devijacija oko aminskih atoma azota upravo otkriva činjenicu da postoje kompromisne strukture (stabilni heksadentati) u seriji diaminotetrakarboksilatnih kompleksa dvovalentnih metala. Molekulsko orbitalna analiza ide u prilog ovoj tvrdnji, a što se naročito može zaključiti korelacijom energija prenosa naelektrisanja između fragmenata (metal i edta-tip liganda) i broja petočlanih helatnih prstenova. Kao konačan zaključak može se reći da nesimetričnost liganda (stvorena različitim brojem ili veličinom karboksilnih grupa na atomima azota) prouzrokuje veću ili manju nestabilnost heksadentatnog helatnog kompleksa. Chelators are kind of chemical compounds with two or more donor atoms. They are having a uniqe property to chelate (multicoordination of metal ions) metal ions and atoms. EDTA (ethylenediaminetetraacetic acid) and its analogues are found as a detoxification agents of certain environmental matrix (it is water usually) polluted by metal ions and also as a markers for their use in early cancer discovering. Taking these facts into accounts the synthesis of several missing nickel(II) complexes has been proposed for the main goal of this dissertation in order to make complete the whole set of the simple chelate diamintetracarboxylate complexes. An in-depth analysis has been carried out for all the prepared compounds paying particular attention to the results of X-ray diffraction analysis and modern quantum-mechanical modeling applied to prepared complexes. Basic goal of this work is to investigate causative-consequent realations of the number of five-membered and six-membered chelate rings in the molecule, their distribution in the complex, stereochemistry and electron configurations. Here, several different kinds of chelates such as: pentadentates of diamintricarboxylate-type (H3ed3a, H3ed3р, H3edа2р, H31,3-pd3a, H31,2-pd3a и H31,2-pd2aр); hexadentates of diamintetracarboxylate-type (H41,3-pd3ap)., have been prepared and characterized. The chelating agents have been used for preparation of corresponding nickel(II) complexes. On the basis of X-ray diffraction analysis it was established that the most stable hexadenate chelates are those with equal distribution of five-membered and six-membered chelate rings. The correlation diagram between an octahedral angle deviation around metal ion and tetrahedral angle deviation around coordinated amine nitrogens reveals the fact that compromise structures (stable hexadentates) from whole set of divalent metal diamintetracarboxylate complexes exist. The results of molecular-orbital analysis further support such a claim particularly correlating charge transfer energies between fragments (metal and edtatype of ligand) and the number five-membered rings. As a final conclusion it might be stated that the chelate asymmetry (make by the different number or the size of carboxylate groups attached to amine nitrogens) cause more or less instability of the hexadentate chelate complexes.

Mehanizam nukleofilnih supstitucionih reakcija kompleksa Pt(IV) i dinuklearnih kompleksa Pt(II) Jovanović, Snežana, 1982- Ispitivanje kompleksa platine značajno je sa biološkog i medicinskog aspekta. Dobro je poznato da se neki kompleksi platine(II) jona, kao što su cisplatina, karboplatina i oksaliplatina, intenzivno koriste u hemioterapiji kao antitumorski reagensi. Poslednjih 40 godina veliki broj drugih jedinjenja platine(II) sintetisano je sa ciljem da se postigne bolja aktivnost i manja toksičnost u odnosu na cisplatinu. Ova istraživanja su proširena i na sintezu i karakterizaciju neklasičnih kompleksa platine, kao što su kompleksi platine(IV) ili polinuklearni kompleksi platine(II). Mehanizam na osnovu koga kompleksi platine ispoljavaju antitumorsku aktivnost još uvek nije potpuno jasan. Smatra se da je to posledica interakcije kompleksa sa molekulom DNK. Eksperimenti su pokazali da je koordinovanje cisplatine za molekul DNK kinetički kontrolisan proces. Sa druge strane, upotreba antitumorskih jedinjenja platine u medicini ograničena je pojavom mnogobrojnih sporednih efekata i rezistentnosti. Takođe, mala rastvorljivost u vodi je dodatni problem koji umanjuje kliničku upotrebu ovih jedinjenja. The chemistry of platinum complexes is important from biological and medical point of view. It is well known that some complexes of platinum(II), such as cisplatin, carboplatin and oxaliplatin, are frequently used in chemotherapy as an anticancer reagents. In the last 40 years a large number of other platinum(II) compounds are synthesized in order to achieve higher activity and lower toxicity in relation to cisplatin. These studies were extended to the synthesis and characterization of some non-classical platinum complexes, such as platinum(IV) complexes or polynuclear platinum(II) complexes. Based mechanism in which platinum complexes exhibit antitumor activity is not clear yet. But, a number of published results explain that the antitumor activity of platinum compounds is a result of complex interactions with DNA molecule. Experiments have shown that the coordination of cisplatin to DNA molecule is kinetically controlled process. On the other hand, the application of platinum anticancer compounds in medicine is limited by the numerous side effects and resistance. Also, low solubility in water is another problem which reduces the clinical use of these compounds.

Kinetika i mehanizam fenilselenoeterifikacije (Z)- i (E)-heks-4-en-1-ola Divac, Vera, 1978- U okviru ove disertacije izvršena su detaljna ispitivanja kinetike i mehanizma intramolekulskih ciklizacija (Z)- i (E)-heks-4-en-1-ola sa fenilselenilhalogenidima (PhSeCl i PhSeBr) u prisustvu i odsustvu nekih Luisovih kiselina (SnCl2, CoCl2, AlCl3, CdCl2) i Luisovih baza (trietilamin, 2,2'-bipiridin, piridin, hinolin). Reakcije ciklizacije ovih supstrata izvođene su na sobnoj temperaturi u metilen hloridu kao rastvaraču pri čemu su dobijeni umereni prinosi cikličnih etara uz pojavu adicionih proizvoda. Dodatkom Luisovih kiselina i baza kao aditiva u katalitičkim i ekvimolarnim količinama primećeno je da je reakcija ciklizacije supstrata favorizovana u prisustvu aditiva dajući gotovo kvantitativne prinose cikličnih etara, dok se prinosi adicionih proizvoda kreću ispod 1% u većini slučajeva. Pored uticaja na prinos cikličnih etara, prisustvo aditiva utiče i na stereoselektivnost ovih reakcija. Ciklizacijom (Z)-heksenola sa svim Luisovim bazama dominantno se dobija tetrahidrofuranski eritro-izomer, dok se u prisustvu Luisovih kiselina kao jedini proizvod dobija treo-izomer. Ciklizacijom (E)- heksenola sa Luisovim bazama u višku se dobija tetrahidropiranski cis- izomer, a korišćenjem pomeutih Luisovih kiselina dobija se trans-izomer u gotovo kvantitativnim prinosima. Iz ovih rezultata može se zaključiti da pravilnim odabirom supstrata ((Z)- ili (E)-heksenola) i aditiva (Luisova kiselina ili baza) reakcijom fenilselenoeterifikacije možemo ciljano dobiti željeni stereoizomer u skoro kvantitativnim prinosima, što ove reakcije čini gotovo stereospecifičnim, sa izuzetkom sinteze tetrahidropiranskog cis-izomera koji se javlja u višku 85:15 u odnosu na trans-izomer. Najbolje rezultate po pitanju selektivnosti i prinosa pokazali su SnCl2 i Et3N kao aditivi. In this thesis the detailed study of kinetic and mechanism of intramolecular cyclization of (Z)- and (Е)-hex-4-en-1-ols with phenylselenyl halides (PhSeCl and PhSeBr) in the presence and absence of some Lewis acids (SnCl2, CoCl2, AlCl3, CdCl2) and some Lewis bases (triethylamine, 2,2’-bipyridine, pyridine, quinoline) are done. Cyclization reactions of these substrates were performed at room temperature in methylene chloride as a solvent, where the moderate yields of cyclic ether products were obtained with the occurrence of products of addition. With the addition of Lewis acids and bases as additives, in the catalytic and the equimolar amount, it is noticed that the cyclization reaction of the substrates is favored in the presence of the additives giving the quantitative yields of cyclic ethers, while the yields of products of addition are below 1% in most cases. Besides the impact on yields of cyclic ethers, the presence of additives also influences the stereoselectivity of these reactions. By the cyclization of the (Z)- hexenol in the presence of all Lewis bases, the tetrahydrofuran type of erythroisomer is dominantly formed, while in the presence of Lewis acids the threoisomer is obtained as unique product. By the cyclization of (E)-hexenol in the presence of Lewis bases, the tetrahydropyran type of cis-isomer is gained in exces, while by the usage of mentioned Lewis acids the trans-isomer is formed in almost quantitative yields. From these results it can be concluded that the proper selection of substrate ((Z)- or (Е)-hexenol) and additive (Lewis acid or base) by the reaction of phenylselenoetherification we can get the desired stereoisomer in almost quantitative yields, which these reactions makes almost stereospecific, with the exception of synthesis of the THP-type of cis-isomer which is formed in exces with ratio 85:15 in regard to trans-isomer. The best results in terms of stereoselectivity and yields gave SnCl2 and Et3N as additives.

Mehanizam ciklizacionih reakcija za sintezu prekursora nekih fizioloških važnih jedinjenja Rvović, Marina, 1981- Supstituisana heterociklična kiseonikova jedinjenja, posebno ciklični etri terahidrofuransko- i terahidropiranskog tipa, privlače posebnu pažnju poslednjih godina, jer predstavljaju strukturne jedinice mnogih prirodnih proizvoda. Veliki broj ovih jedinjenja ispoljava citotoksičnu ili antibiotsku aktivnost. Zbog izuzetnog značaja ove klase molekula razvijen je veliki broj metoda za sintezu njihovih prekursora. Danas je dobro poznato da ciklofunckionalizacija nezasićenih alkohola pomoću elektrofilnih selenovih reagenasa predstavlja efikasnu metodu za sintezu ovog tipa kiseoničnih heterocikala. Prednosti ove metode se ogledaju u tome da se uvođenje heteroatoma u ciklični molekul, transformacija dobijenih proizvoda i uklanjanje funkcionalnih grupa u bočnom lancu dešavaju pri jednostavnim i blagim reakcionim uslovima. Prisustvo pažljivo odabranog katalizatora u ovim reakcijama može uticati na promenu raspodele reakcionih proizvoda i poboljšanje prinosa cikličnih etara. Iako su ove reakcije detaljno ispitivane, ostaje pitanje uloge katalizatora na kinetiku i mehanizam reakcija. Substituted oxygen heterocycles, particularly cyclic ethers of tetrahydrofuran- and tetrahydropiran- types, have attracted special attention in recent years due to their occurrence as structural units of many marine natural products. A considerable fraction of these compounds exhibits notable cytotoxic and antibiotic activities. Due to the importance of this class of molecules, a number of methods have been developed for construction of its precursors. It is now well established that selenium-induced cyclofunctionalization of unsaturated alcohols represents a useful method for the synthesis of this type of oxygen heterocycles. This synthetic protocol has advantage that introduction of heteroatom, the manipulation of obtained product and the removal of the function in side chain is facilitated by simple and mild experimental conditions. The presence of properly selected catalyst can change distribution and improve the yields of obtained cyclic ether precursors. While the reaction has been thoroughly studied, questions remain pertaining to the role of catalyst on reaction kinetics and mechanistic pathway.

Statistička teorija uzročnosti, stohastičke diferencijalne jednačine i svojstvo martingalne reprzentacije Valjarević, Dragana, 1976- One of the important and basic goals of science is to establish cause-e®ect re- lations between events. Many discussions were about the concept of causality and how it can be measured. The concept of Granger's causality (Granger, 1969) is very well known in economy and it can be applied in researches. Granger's de¯nition of causality is based on the idea that the present and the future cannot e®ect the past. About the concept of causality have been discussed for a very long time in all areas of science. In last decade we are dealing with a signi¯cant progress. Today, a concept of causality have a wide application in physical, biological andsocial sciences, history, medicine, especially in epidemiology, economy and etc. The area of research of this Phd dissertation is statistical theory of causality and its application on weak solutions of stochastic di®erential equations and martingale representation property. It have been shown that this concept of causality is equivalent with the concept of weak uniqueness of weak solutions for the stochastic di®erential equations and extremal solutions of the martingale problem. This concept of causality can be characterized with stopping times and its connection with extremal solution of the stopped martingale problem can be proved, as well as with locally unique weak local solutions. The concept of causality can be related to the theory of martingales, too. Namely, this concept can be connected with the preservation of the martingale property, orthogonal martingales, stable subspaces as well as with martingale representation property, which have an application, especially in ¯nancial mathematics.

Procena efekata preoperativne primene klaritromicina u lečenju nosno-sinusne polipoze Effects of preoperative clarithromycin administration in treatment of sinonasal polyposis Perić, Aleksandar, 1971- nosni sekret, alergijski rinitis, klaritromicin, citokini The concentrations of inflammatory mediators in nasal secretions could reflect the inflammatory status of the nasal mucosa and evolution of sinus disease. The results of previous investigations suggest that macrolide antibiotics could be effective in the treatment of chronic rhinosinusitis and nasal polyposis. The mean goal of this study was to compare the efects of preoperative clarithromycin administration and surgical treatment with sole surgical treatment in patients with nasal polyposis. Therefore, we assessed the immunomodulatory and clinical efects of long-term low-dose clarithomycin treatment in allergic and non-allergic patients with nasal polyps. Koncentracije medijatora zapaljenske reakcije u nosnom sekretu odražavaju status zapaljenja sluzokože nosa, kao i razvoj zapaljenske bolesti u paranazalnim sinusima. Rezultati prethodnih istraživanja sugerišu da primena makrolidnih antibiotika može biti efikasna u lečenju hroničnog rinosinuzitisa i nosno-sinusne polipoze. Osnovni cilj istraživanja bio je da se uporede efekti preoperativne primene makrolidnog antibiotika klaritromicina i naknadnog hirurškog lečenja sa efektima isključive primene hirurškog lečenja u bolesnika sa nosno-sinusnom polipozom. Osim toga, bilo je potrebno proceniti imunomodulacijske i kliničke efekte dugotrajne, niskodozirane terapije klaritromicinom u alergičnih i nealergičnih pacijenata sa nosnom polipozom.

Uticaj lekova na nivo TSH kod pacijenata na supstitucionoj terapiji tiroksinom The impact of drugs on TSH level of patients’ using levothyroxin replacement therapy Anđelković, Marija, 1977- levotiroksin,interakcija lekova, ACE inhibitori, selektivni beta blokatori, Ca antagonisti, nitrarti, statini, TSH Hypothyroidism requires thyroxine replacement, regardlesss thyroidectomy was performed or not. The goal of this research was to determine how different groups of drugs – ACE inhibitors, selective beta blockators, Ca antagonists, nitrates, statins, or different combinations of these drugs affect TSH level at the patients on the thyroxine replacement therapy after total thyroidectomy. Research took place in 2012 and was performed on the outpatients that check their chormones at Department of Nuclear Medicine in Clinical Center Kragujevac. 247 patients were divided into groups depending on which drugs they had been prescribed. The control group involved patients taking just thyroxine without other medication. TSH level of patients in control group was compared with TSH level of patients in groups taking other drugs. Our study showed that patients that use selective beta bloskators have significantly higher level of TSH than patients that don’t take these drugs. TSH level in the grops of patients using all other drugs did not differ from the control group.

Utvrđivanje nutritivne vrednosti proizvoda koji sadrže Helianthus tuberosus L., Asteraceae Determination of nutritional composition of the products containing Helianthus tuberosus L. Asteraceae Radovanović, Ana M., 1985- Helianthus tuberosus, tehnologija ekstruzije, glikemijski indeks,glikemijsko opterećenje Helianthus tuberosus (Jerusalem artichoke) is a low - caloric source of inulin, minerals and low level of fat. It is not sufficiently present in the human diet, although it can serve as a good starting material for functional food products. The aim of this research was to formulate and produce innovative products containing different amount of Jerusalem artichoke as the main component, and buckwheat flour as a bulking agent. There have not been data on the processing Helianthus tuberosus by extrusion technology. This is the first time Jerusalem artichoke undergoes extrusion technology in order to produce test products which were characterised by nutritional value, glycemic index (GI) and glycemic load (GL). Four types of extruded products were prepared by extrusion technology - three types of test product containing 30 %, 60 % and 80 % of Jerusalem artichoke and control product with no Jerusalem artichoke. Nutritional composition of the test products was characterized by content of water, dry matter, fat, proteins, sugars, total carbohydrates, dietary fiber and inulin. Glycemic index values for test and control products were obtained in prospective, clinical study on healthy volunteers, using the reference methodology of glycemic index determination. Glycemic load values for test and control products were calculated based on obtained values of glycemic index. The study results showed favorable nutritional properties of obtained extruded products with Jerusalem artichoke content – high content of inulin and low content of fat. Consumption of fresh Jerusalem artichoke is limited by its organoleptic properties, which was improved by extrusion processing. Increasing content of Jerusalem artichoke in test products caused significant decrease of glycemic index and glycemic load values, as well as in control products. According to Brand-Miller's classification test product containing 30 % of Jerusalem artichoke was classified as medium GI and medium GL, test product containing 60 % of Jerusalem artichoke was classified as medium GI and low GL, test product containing 80 % of Jerusalem artichoke was classified as low GI and low GL products, while control product with no content of Jerusalem artichoke showed a high GI and medium GL value. Consuming food with high glycemic index and glycemic load influences development of chronic diseases, which justifies consumption of food with low glycemic index and glycemic load in order to promote health. Results of this study shows that Jerusalem artichoke is possible to use in extrusion technology in such manner so that test products containing 60 % and 80 % of Jerusalem artichoke have favorable values of GI and GL for promoting health. Helianthus tuberosus (čičoka), biljni nisko-kalorični izvor energije, inulina, minerala i neznatne količine masti je malo zastupljena u ishrani, a predstavlja dobar polazni materijal za proizvodnju funkcionalnih proizvoda. Cilj ovog istraživanja je formulacija i proizvodnja inovativnih prizvoda sa različitim sadržajem čičoke kao glavne komponente i heljdinim brašnom kao sredstvom za dopunjavanje. Do sada nisu zabeleženi podaci o obradi vrste Helianthus tuberosus tehnologijom ekstruzije. Prvi put je tehnologija ekstruzije primenjena na biljnu sirovinu čičoku i dobijeni proizvodi su okarakterisani nutritivnom vrednošću, glikemijskim indeksom (GI) i glikemijskim opterećenjem (GO). Primenom specifičnih uslova ekstruzije za svaki proces ponaosob, dobijene su tri vrste test proizvoda koji sadrže 30 %, 60 % i 80 % čičoke i kontrolni proizvod bez sadržaja čičoke. Nutritivni sastav test proizvoda okarakterisan je sadržajem vode, suve materije, masti, proteina, šećera, ukupnih ugljenih hidrata, inulina i dijetnih vlakana. Vrednosti glikemijskog indeksa test i kontrolnih proizvoda dobijene su primenom referentne metodologije i smernica za standardno određivanje glikemijskog indeksa, u prospektivnoj, kliničkoj studiji izvršenoj na grupi zdravih ispitanika. Glikemijsko opterećenje je određeno na osnovu dobijenih vrednosti glikemijskog indeksa. Rezultati istraživanja su pokazali povoljne nutritivne osobine dobijenih ekstrudovanih proizvoda sa sadržajem čičoke - visok sadržaj inulina i nizak sadržaj masti. Metodom ekstruzije korigovane su organoleptičke osobine svežih krtola čičoke koje ograničavaju njihovo konzumiranje. Sa povećanjem sadržaja čičoke u test proizvodima uočeno je značajno opadanje GI i GO vrednosti. Prema Brand-Miller-ovoj klasifikaciji test proizvodi koji sadrže 30 % čičoke se svrstavaju u kategoriju srednjih vrednosti GI i GO, test proizvodi koji sadrže 60 % čičoke se svrstavaju u kategoriju srednje vrednosti GI i niske vrednosti GO, test proizvodi koji sadrže 80 % čičoke pripadaju kategoriji niskih vrednosti GI i GO, dok kontrolni proizvodi, bez sadržaja čičoke, imaju visoku vrednost GI i srednju vrednost GO. Konzumiranje namirnica sa visokim vrednostima GI i GO utiče na razvoj hroničnih bolesti zbog čega je opravdana upotreba namirnica sa niskim GI i GO u cilju očuvanja zdravlja. Rezultati ovog istraživanja pokazuju da se na čičoku može primeniti proces ekstruzije tako da dobijeni test proizvodi koji sadrže 60 % i 80 % čičoke imaju povoljne vrednosti GI i GO za očuvanje zdravlja.

Analiza parametara glikoregulacije, liporegulacije i parametara funkcije štitaste žlezde tokom trudnoće The analysis of parameters of glicoregulation, liporegulation and thyroid function during pregnancy Mladenović, Violeta Trudnoća, gestacijski dijabetes melitus, tiroidna funkcija 616 Trudnoća predstavlja stanje rezistencije na insulin koja u ne kih žena može da predisponira razvoj dijabetesa, koji je udružen sa povećanim rizikom i po majku i po plod. Tokom trudnoće su česti i poremećaji tiroidne funkcije, posebno autoimunska tiroidna bolest (AITB) i hipotiroidizam. Osnovni cilj istra živanja je analiza pa rametara glikoregulacije, liporegulacije i parametara funkcije štitaste žlezde tokom trudnoće. Istraživanje predstavlja kliničku, opservacionu, neinterventnu, analitičku, prospektivnu, kohortnu studiju, sprovedene u jednom centru. Osnovni kriterijum i za uključivanje pacijenata u studiju su bili: ženski pol, starost iznad 18 godina i postavljena dijagnoza vitalne i željene trudnoće u prvom trimestru. Protokol istraživanja je podrazumevao da ono bude obavljeno tokom četiri posete pa cijentkinja (u 1., 2. i 3. trimestru trudnoće, kao i četiri nedelje posle porođaja): OGTT sa 100g glukoze, sa određivanjem glikemije i insulinemije u 0, 60, 120 i 180 minutu, HbA1c, parametri funkcije štitaste žlezde (fT4, fT3, TSH, antiTG antitela, antiTPO antitela, kalcitonin), standardne laboratorijske analize, lipidogram (tHol, HDL, LDL, TAG. U dalje istraživanje su uključe ne samo pacijentkinje koje su imale sve uključujuće i ni jedan isključujući kriterijum. Na osnovu rezultata OGTT stratifikovali smo ispitanice u tri grupe: normalna tolerancija glukoze (NTG), minimalni poremećaj glikoregulacije (MPG) i gestacijski dijabetes melitus (GDM), odnosno u dve grupe : normalna tolerancija glukoze (NTG) i patološka tolerancija glukoze (PTG=MPG+G DM). Pregnancy presents a state of insulin resistance that can predipose diabetes development in some women, and is associated with increased risk for neonate and for mother. During pregnancy are often thyroid disorders, especially autoimmune thyroid disease (AITD) and hypothyreoidism. The main goal of the research was analysis of parameters glicoregulation, liporegulation and thyroid function during pregnancy. This research presents clinical, observational, noninterventional, analytic, prospective, cohort study, conducted in one center. Inclusion criteria were: female gender, older than 18 years and diagnosis of vital and desired pregnancy in the first trimester. Study protocol imply that it should be done during four visits (1st, 2nd and 3rd trimester, and 4 weeks after delivery): ОGТТ with 100 g glucose, with specifying glicemia and insulinemia in 0. , 60. , 120. and 180. minutes and HbA1c, thyroid function parameters (fТ4, fТ3, ТSH, antiТG antibodies, antiТPO аntibodies, calcitonin), standard laboratory analysis, lipids (tHol, HDL, LDL, TAG). According to OGTT results we divided patients in three groups : normal glucose tolerance (NGT), minimal disorder of glicoregulation (МDG) and gestational diabetes mellitus (GDM), respectively in two groups : normal glucose tolerance and pathologic glucose tolerance (PTG=MDG+GDM). The research included 92 pregnant women with diagnosis of vital and desired pregnancy in the first trimester, while 77 finished examination. Patients were average 30,8±4,7 (19-41) years old. It was shown that there was impact the number of risk factors on degree of glucose tolerance disorder (р=0,034), while most of patients had no risk factor (48%). From 77 patients, the 9 was with GDM, 9 was with MPG (18 with PTG). As pregnancy progress, disorder of glucose tolerance increased (in 2nd and 3rd trimester), while four weeks after delivery all were with NTG. The average insulinemia during pregnancy is the greatest in 1st and 2nd trimester in MDG group in 60. and 120. minute, in GDM group in 120. minute, during 3rd trimester greatest in 0. and 60. minute in MDG group, while in 120. and 180. minute greatest in GDM group. The average insulinemia during pregnancy is significantly great in PTG.

Značaj kvantifikacije markera onkogeneze u tkivnim isečcima obolelih od planocelularnog karcinoma larinksa i hroničnog laringitisa The importance of quantifying markers of oncogenesis in tissue slices of patients with squamous cell carcinoma of the larynx and chronic laryngitis Stojanović, Stevan P. larinks, karcinom, hronični laringitis, cyclin D1, FGF3, p16, p21 hronični laringitis Progresija hroničnog laringitisa i nastanak karcinoma larinksa vezan je za aktivaciju različitih onkogena i inaktivaciju tumor supresorskih gena. Proteinski produkti ovih gena se imunohistohemijski detektuju u tkivnim isečcima obolelih pacijenata. Utvrđeno je da karcinomi larinksa sa istim kliničkim i histološkim osobenostima imaju različito biološko ponašanje, a samim tim i prognozu. Hronični laringitisi se karakterišu displazijom koja se može stepenovati u tri stadijuma i kod koje postoji takođe izmenjena ekspresija onkogena i antionkogena. Klinički i histološki nalaz dopunjeni imunohistohemijskim bojenjem tkivnih preparata pružaju dodatnu infomaciju neophodnu u tretiranju hroničnog laringitisa i karcinoma larinksa. Najčešće je izmenjena ekspresija onkogena cyclin D1 i FGF3 kod hroničnog laringitisa i karcinoma larinksa. Od tumor supresorskih gena veoma često su alterisani p16 i p21.

Trend upotrebe psihotropnih lekova kod članova porodica vojnih lica Jovičić, Uglješa B., 1958- Neuroze, borbena dejstva uotreba lekova, agresija, borbena dejstva, komorbiditet Uvod. Osobe u sistemu vojnog zdravstva predstavljaju jednu od specifičnih populacija stanovništva, koja obuhvata osobe širokih dobnih kategorija i profesionalnih zaduženja, uključujući aktivni i penzionisani sastav. Pripadnici porodica aktivnih vojnih lica takođe čine osobe sa specifičnim faktorima povezanim sa zdravljem. U većem broju studija je pokazano da period nakon povratka pripadnika aktivnog sastava iz situacija neposrednog vojnog angažovanja korelira sa značajnim reperkusijama na porodične relacije i mentalno zdravlje članova čitave porodice. Ovakve specifičnosti, vrlo verovatno, utiču i na poseban profil propisanih psihotropnih lekova u ovoj subpopulaciji stanovništva. Cilj istraživanja je bio da se izvrši analiza trenda upotrebe psihofarmaka kod članova porodica vojnih lica Srbije. Osnovna pretpostavka je bila da je obim i struktura propisivanja pojednih podgrupa psihofarmaka bila različita u dva posmatrana perioda. Metod. Ispitivanje je sprovedeno kao retrospektivno istraživanje potrošnje psihotropnih lekova prema ATC/DDD metodologiji, pri čemu su podaci izraženi kao broj utrošenih dnevnih definisanih doza (DDD) na 1000 vojnih osiguranika – članova porodica vojnih lica, na dan. Ovo ispitivanje je dizajnirano kao istraživanje sekularnog trenda propisivanja lekova, u sistemu vojnog zdravstva Srbije, sa dva trogodišnja preseka, sa razmakom od 10 godina. Studijsku populaciju su činili svi odrasli osiguranici vojnog zdravstvenog osiguranja van aktivnog sastava, članovi porodica vojnih lica, a kojima se izdaju lekovi iz odgovarajuće apotekarske službe. Broj definisanih dnevnih doza leka na 1000 osiguranika van aktivnog sastava na dan je bila vodeća zavisna varijabla. Zavisne varijable su predstavljale i pojedine podgrupe psihotropnih lekova iz grupe antipsihotika, antidepresiva i anksiolitika, kao i pojedinačni lekovi iz ovih podgrupa. Statistička obrada podataka je obavljena u dva dela: a) analiza upotrebe DDD pojednih lekova i podgrupa lekova i b) statistička analiza obrasca i trenda propisivanja. Obim upotrebe lekova je izražen u relativnim odnosima sa ispitivanom populacijom, a osnovni parametar je bio broj definisanih dnevnih doza leka, pojedniačno u zbirno, na 1000 članova posmatrane populacije propisanih za jedan dan (DDD/1000 stanovnika/1 dan). Rezultati. Rezultati su podeljeni u tri dela: analiza opšteg trenda, analiza razlika upotrebe lekova i analiza upotrebe lekova i ispitivanoj i opštoj populaciji. U prvom delu su dati raspoloživi podaci o potrošnji lekova u periodu 1998-2000 i 2008-2010, za svaku posmatranu godinu. Izvorni podaci su transformisani u relativne odnose pa potom u DDD na 1000 ispitanika. Potom je analizirana upotreba lekova u definisanim dnevnim dozama na 1000 ispitanika po danu, po osnovnim ATC grupama komparativno, u posmatranim trogodišnjim periodima. Analizirana je i prosečna godišnja stopa rasta, prema odgovarajućoj formuli. Dat je i komparativni pregled potrošnje pojedninačnih lekova u oba posmatrana trogodišnja perioda i to za sve lekove i samo za lekove koji su korišćeni o oba perioda. U delu koji se odnosi na analizu razlika upotrebe lekova zbirna upotreba lekova je transformisana u dva perioda, period 1 i period 2. Zatim je dat sumarni pregled potrošnje lekova po periodima, mere centralne tendencije i odstupanja, a razlike između dva uzorka, odnosno dva perioda potrošnje lekova, analizirana su korišćenjem neparametarskog testa. Rezultat je prezentovan u vidu relativne promene upotrebe i promene ranga upotrebe u dva posmatrana perioda. Trend apsolutne upotrebe i ranga svakog pojedinačnog leka koji je bio od interesa je takođe zastupljen u ovom delu analize. U trećem delu rezultata koji je bio opredeljen za analizu upotrebe lekova i ispitivanoj i opštoj populaciji korišćeni su javno dostupni podaci o upotrebi lekova publikovani od strane referentne nacionalne institucije. Ovi rezultati su korišćeni isključivo u svrhu deskriptivne komparacije (korelacije) sa originalnim, izvornim podacima istraživanja. Tržišno učešće i stopa rasta leka na tržištu su takođe bili predmet analize ovog dela rezultata istraživanja.

Uticaj primene različitih beta blokatora na agregabilnost trombocita kod pacijenata sa koronarnom bolešću srca na dvojnoj antiagregacionoj terapiji The influence of different beta-blockers on platelet aggregation in patients with coronary heart disease оn dual antiplatelet therapy Ignjatović, Vladimir S., 1981- antiagregaciona terapija, beta blokatori, antiagregaciona terapija, koronarna bolest agregabilnost trombocita Primena beta blokatora u lečenju pacijenata sa koronarnom bolešću srca povezana je sa smanjenjem učestalosti anginoznih tegoba i mortaliteta pacijenata. Zbog same težine bolesti i prethodnih kardiovaskularnih intervencija mnogi pacijenti sa koronarnom bolešću koriste dvojnu antiagregacionu terapiju u cilju postizanja veće inhibicije agregabilnosti trombocita. Uticaj beta blokatora na agregabilnost trombocita kod pacijenata koji koriste antiagregacionu terapiju je nedovoljno ispitan. Cilj: Ispitati uticaj različitih beta blokatora na agregabilnost trombocita kod pacijenata koji koriste dvojnu antiagregacionu terapiju. Metodologija: Istraživanje je obuhvatilo 331 pacijenta, lečenih na Klinici za kardiologiju KC Kragujevac u toku 2011. godine. Pacijenti su podeljeni u četiri grupe u zavisnosti od vrste beta blokatora koji su koristili (bisoprolol, nebivolol, metoprolol, karvedilol). Agregabilnost trombocita je merena primenom multiplate analizatora i izražena kroz vrednost ADP testa (za procenu efekta klopidogrela), ASPI testa (za procenu efekta ASK), TRAP testa (za procenu bazalne agregabilnosti trombocita) kao i odnos ADP/TRAP i ASPI/TRAP koji predstavljaju stepen inhibicije agregabilnosti trombocita u odnosu na bazalnu vrednost. U obzir je uzeta i zastupljenost demografskih, kliničkih parametara, vrednosti laboratorijski parametara i zastupljenost grupa kardivaskularnih lekova između poređenih grupa. Rezultat: Pacijeneti koji su koristili nebivolol imali su značajno nižu vrednost odnosa ADP/TRAP testa (0,39 ± 0,30) u odnosu na pacijente koji su koristili bisoprolol (0,48 ± 0,26; p=0,038), kao i trend ka nižoj vrednosti ADP testa (328,0 ± 197,3 prema 403,7 ± 213,2; p=0.059) dok nije bilo statistički značajne razlike u vrednosti laboratorijskih parametara funkcije trombocita između ostalih poređenih grupa. Zaključak: Pacijenti sa koronarnom bolešću srca na dvojnoj antiagregacionoj terapiji koji su koristili nebivolol imali su statistički značajno niži nivo rezidualne, ADP indukovane agregabilnosti trombocita u odnosu na bazalnu vrednost od pacijenata koji su koristili bisoprolol. The use of beta-blockers in the treatment of patients with coronary heart disease is associated with a decrease in the frequency of angina pectoris and mortality of patients. Due to the severity of the disease and previous cardiovascular interventionс, many patients with coronary artery disease usе dual antiplatelet therapy to achieve greater inhibition of platelet aggregation. The influence of beta blockers on platelet aggregation in patients using antiplatelet therapy is not well understood. Objective: To examine the effect of different beta-blockers on platelet aggregation in patients on dual antiplatelet therapy . Methodology: The study included 331 patients 122 who were treated at the Department of Cardiology, Clinical Center Kragujevac during the 2011th year. Patients were divided into four groups depending on the type of betablockers that are used ( bisoprolol, nebivolol, metoprolol, carvedilol ). Platelet aggregation was measured using the multiplate analyzer and expressed through the value of ADP test (to assess the effect of clopidogrel), ASPI test (to assess the effect of ASA) TRAP test ( to assess baseline platelet aggregation ) and the ratio of ADP/TRAP and ASPI/TRAP representing the degree of inhibition of platelet aggregation compared to the basal value. In consideration was taken the representation of demographic, clinical characteristics, laboratory parameters and cardiovascular medications between the groups. The result : patients which used by nebivolol had a significantly lower value of the ratio of ADP/TRAP (0.39±0.30) compared to patients who used bisoprolol (0.48 ±0.26, p =0.038), and trend toward lower values ADP test ( 328.0±197.3 vs 403.7 ± 213.2, p =0.059) while there was no statistically significant difference in values of other laboratory parameters of platelet function between other groups. Conclusion : Patients with coronary artery disease on dual antiplatelet therapy who used nebivolol had significantly lower levels of residual ADP-induced platelet aggregation compared to baseline than patients who used bisoprolol.

Značaj modulacije kalijumskih kanala i azot monoksida (NO) u mehanizmu relaksantnog efekta pinacidila i pentoksifilina Kordić Bojinović, Jelena, 1977- pentoksifilin, protamin, pinacilid Radna hipoteza: Pinacidil, otvarač K+ kanala (OKK), dovodi do relaksacije glatke muskulature uterusa pacova, bez obzira na način aktivacije i tip kontrakcija, modifikujući funkciju K+ kanala. U ovaj proces relaksacije uključeni su KATP kanali. Pentoksifilin u svom mehanizmu delovanja uključuje otvaranje kalijumskih kanala i/ili signalne puteve NO. Cilj: Utvrđivanje uloge otvarača kalijumskih kanala u sprečavanju neželjenih kontrakcija uterusa, uz najavu razvoja novog specifičnog tokolitika. Metoda: Eksperimenti na izolovanom uterusu pacova. Rezultati i zaključak: Pentoksifilin, protamin-sulfat i pinacidil izazivaju koncentracijski-zavisnu relaksaciju, koja zavisi od tipa aktivacije izolovanog uterusa. Najsnažniji efekt su ispoljili na spontanu ritmičku aktivnost, a najslabiji na kontrakcije izolovanog uterusa prouzrokovane acetilholinom. U mehanizmu relaksantnog delovanja pentoksifilina nije značajno zastupljeno otvaranje ATP kalijumskih kanala. Međutim, otvaranje BKCa i voltažno - zavisnih Ca2+ kalijumskih kanala ima izvestan značaj, ali u različitom stepenu, u mehanizmu relaksantnog delovanja pentoksifilina na spontanu ritmičku aktivnost i kontrakcije prouzrokovane sa kalcijumom. Obzirom da relaksantni efekt pentoksifilina zavisi i od koncentracije kalcijuma u medijumu, može se reći da pentoksifilin, u izvesnoj meri, deluje kao kalcijumski antagonist. Dobijeni rezultati su dodatna potvrda o dominaciji NO/cGMP signalinih puteva, kojima pentoksifilin prouzrokuje relaksaciju glatkih mišičnih ćelija uterusa, kao i da bi on mogao da bude potencijalni tokolitički lek. Protamin-sulfat izaziva relaksaciju koja se odvija putem kalijumskih kanala i u izvesnoj meri preko adrenergičkih receptora i posredstvom azot monoksid (NO)-zavisnih puteva. Od značaja je i uloga ciklooksigenaze, jer je indometacin, s jedne strane značajno potencirao relaksantni efekt protamin-sulfata na spontanu ritmičku aktivnost, a s druge strane, smanjivao je njegov efekt na kontrakcije izolovanog uterusa pacova indukovane kalcijumom. Pinacidil je inhibirao spontanu ritmičku aktivnost izolovanog uterusa pacova (malim delom posredstvom aktivacije KATP kanala), kao i kontrakcije prouzrokovane električnom stimulacijom, (KK), ali i kalijum – nezavisnim mehanizmima koji su povezani sa intracelularnom koncentracijom Ca2+ i/ili cGMP putem. Ca2+ - indukovanu kontraktilnost, pinacidil je inhibirao većim delom putem aktivacije BKCa. Working hypothesis: pinacidil, K + channel opener , leads to relaxation of smooth muscles of the uterus of rats, regardless of the method of activation and contraction type, modifying the function of K+ channels. In this relaxation process are included KATP channels. Pentoxifylline in its mechanism of action involves the opening of potassium channels and / or signaling pathways NO. Objective: Determining the role of the opening of potassium channels in preventing unwanted contractions of the uterus, with the announcement of the development of new specific tocolytics. Method: Experiments on isolated rat uterus. Results and Conclusion : Pentoxifylline, protamine sulfate and pinacidil caused a concentration - dependent relaxation, which depends on the activation of the isolated uterus. The strongest effect was manifested in spontaneous rhythmic activity and lowest on isolated uterine contractions caused by acetylcholine. The mechanism of the relaxant effect of pentoxifylline did not significantly present opening ATP potassium channels. However, the opening of voltage dependent BKCa and Ca2 + potassium channel has some significance, but to varying degrees, in the mechanism of the relaxant effect of pentoxifylline on spontaneous rhythmic activity and contraction caused by the calcium. Since pentoxifylline relaxant effect depends on the concentration of calcium in the medium, it can be said that pentoxifylline , to some extent , act as a calcium antagonist . The results are further evidence of the dominance of NO / cGMP signalinih roads, which pentoxifylline causes relaxation of smooth muscles of the uterus, and that he could be a potential drug toxicolytical. Protamine sulfate causes relaxation that takes place through potassium channels, and to some extent through adrenergic receptors and by nitric oxide (NO)- dependent pathways. Also of importance is the role of cyclooxygenase, because indomethacin, on the one hand significantly potentiates the relaxant effect of protamine sulfate on spontaneous rhythmic activity, on the other hand, decreasing its effect on the contraction of isolated rat uterus induced calcium. Pinacidil inhibited the spontaneous rhythmic activity of isolated rat uterus (small part through activation of KATP channels) and contraction caused by electrical stimulation, and potassium - independent mechanisms that are associated with the intracellular concentration of Ca 2 + and / or cGMP through. Ca2 + - induced contractility pinacidil inhibited mainly by activation of BKCa.

Planiranje eksperimenta za robusnu identifikaciju dinamičkih sistema Stojanović, Vladimir, 1983- Primenom principa crne kutije i teorija verovatnoće, stohastičkih procesa i matematičke statistike, uz korišćenje ulazno/izlaznih merenja razmatra se mogućnost dobijanja matematičkih modela. Okviri za dobijanje modela su opšti jer se pretpostavlja da su stohastički poremećaji negausovi. Takav model je preduslov za projektovanje široke klase industrijskih regulatora. Teorija planiranja eksperimenta ima važnu ulogu u povećanju brzine konvergencije rekurzivnih algoritama kao i u skraćenju vremena identifikacije. Povećana brzina konvergencije algoritama čini ih veoma povoljnim za praktičnu primenu. Ulazni signali za identifikaciju kreiraju se preko rekurzivne relacije za autokovarijacionu funkciju. Sinteza autokovarijacione funkcije zasnovana je na idejama iz prediktivnog upravljanja, pri čemu upravljački signal ima konačan alfabet. Praktična istraživanja pokazuju da poremećaj, u opštem slučaju, ima negausovu raspodelu. Posebno je važan slučaj kada se pojave opservacije koje su nekonzistentne u odnosu na glavninu populacije, autlajeri (outliers). Raspodele verovatnoće za taj slučaj su približno normalne (e -kontaminirane) i predmet su intenzivnog proučavanja u matematičkoj statistici. Za takav slučaj se predlažu robusni algoritmi identifikacije, pri čemu robusnost ima statistički karakter. Razmatra se primena robusnog Kalmanovog filtra u identifikaciji modela zasnovanih na grešci izlaza. Robusni prošireni Kalmanov filtar se koristi za identifikaciju opšte forme nelinearnog modela u prostoru stanja. Identifikacija procesa opisanih opštim modelom (nepoznati parametri i stanja procesa) zahteva uvođenje proširenog Masreljez-Martinovog filtra. Uvođenjem predloženih heurističkih modifikacija povećava se fleksibilnost, u smislu praktične primene kao i brzine konvergencije robusnog filtra. Prikazana je nadmoćnost predloženih robusnih algoritama u identifikaciji sistema sa vremenski promenljivim parametrima, koji zasnovani na OE klasi modela. Praktični aspekt dobijenih rezultata potvrđen je kroz eksperiment na pneumatskom cilindru koji se nalazi u laboratoriji centra za Automatsko upravljanje i fluidnu tehniku Fakulteta za mašinstvo i građevinarstvo u Kraljevu. By applying the principles of black boxes and probability theory, stochastic processes and mathematical statistics, with the use of input / output measurements, the possibility of obtaining mathematical models is considered. Frames for obtaining the model are general because it is assumed that the stochastic disturbances are non-Gaussian. Such a model is a prerequisite for the design of wide range of industrial controlers. The theory of experiment design plays an important role in increasing the speed of convergence of recursive algorithms as well as shortening the time of identification. Increased speed of convergence of algorithms makes them very favorable for practical application. The input signals for identification are created through the recursive relation for autocovariance. Design of autocovariance is based on the idea of predictive control, where the control signal has a finite alphabet. Practical studies show that disturbances, in general, have non-Gaussian distribution. Particularly important is the case when there are observations that are inconsistent with respect to the majority of population (outliers). Probability distribution for this case is approximately normal (e -contaminated) and is the subject of intensive study in mathematical statistics. In such case, the robust algorithms for identification, where robustness has a statistical nature, are proposed. It is considered the application of robust Kalman filter in identification of output error model. Robust extended Kalman filter is used for identification of the general form of the nonlinear statespace model. Identification of the processes described by general model (the unknown parameters and states of the process) requires the introduction of extended Masreliez-Martin's filter. By introducing of the proposed heuristic modification increases the flexibility in terms of practical application and the speed of convergence of the robust filter. The superiority of the proposed robust algorithms for system identification with timevarying parameters, which are based on OE models, has been shown. The practical aspects of the results have been confirmed by experiment on a pneumatic cylinder, which is located in the laboratory of the centre for automatic control and fluid technique of The Faculty of Mechanical and Civil Engineering in Kraljevo.
