Докторска дисертација Наратив љубави у романима Хулија Кортасара и Милорада Павића посвећена је утицају метафикције на тематику љубави у Кортасаровим и Павићевим романима и начину на који концепција љубави у романима аргентинског и српског писца може обогатити и променити уобичајено разумевање појма метафикције. Наратив љубави уско је повезан са иновативним моделима читања репрезентативних романа Хулија Кортасара и Милорада Павића. Корпусом дисертације обухваћени су романи Школице (Rayuela, 1963), 62. Модел за састављање (62.

The narrative of love is closely connected with the innovative models of reading inaugurated by the representative novels of Julio Cortázar and Milorad Pavić. The dissertation includes the analyses of the novels Hopscotch (Rayuela, 1963), 62. A Model Kit (62. Modelo para armar, 1968) and A Manual for Manuel (Libro de Manuel, 1973) by Julio Cortázar and the novels Dictionary of the Khazars (Hazarski rečnik, 1984), Landscape Painted with Tea (Predeo slikan čajem, 1989) and The Inner Side of the Wind (Unutrašnja strana vetra, 1991) written by Milorad Pavić..

Integrated maintenance model based on establishment of principles of mechanical vibrations change and its impact on prognostics of condition of rotor engines

Osnovni cilj ove disertacije je da se razvije Integrisani model odrţavanja zasnovan na vibracijama sloţenih rotacionih tehniĉkih sistema, odnosno da se uspostavi sprovoĊenje dijagnostiĉkih provera stanja sklopova rotacionih mašina (kontrola vibracija). Zatim da se definišu optimalne periodiĉnosti vibracija kao i identifikacija ocena i rangiranja rizika sa stanovišta prekida rada mašina. Na taj naĉin potvrdiće se glavna hipoteza koja glasi: „Razvijanjem integrisanog modela odrţavanja zasnovanog na uspostavljanju zakonitosti promene mehaniĉkih vibracija moći će da se preventivno predvide pojave neispravnosti i prognozira stanje rotacionih mašina.The basic goal of this dissertation is the development of an Integrated Maintenance Model based on vibrations of complex rotational technical systems, in other words, the establishment of implementation of diagnostic checks of rotating machinery compositions condition (control of vibrations). Afterwards, the definition of optimal periodicity of vibrations, as well as identification of estimations and ranking of risks from the stand point of disruption of work of operational processes. This is the way to confirm the main hypothesis which reads: “Development of an Integrated Maintenance Model based on the establishment of legality of change of mechanical vibrations will enable preventive predicting of malfunction occurrence, as well as prognosis of rotating machinery health

The effects of plaque, some microelements and IgA from the saliva on dental caries

U radu su prikazani rezultati ispitivanja uticaja plaka, nekih mikroelemenata (bakra, gvožđa, olova, fluora i stroncija) i imunoglobulina tipa A na raširenost zubnog karijesa u tri različita područja Srbije. Sadržaj mikroelemenata ispitivan je u pijaćoj vodi i tvrdim zubnim tkivima metodom atomske apsorpdije, a koncentracija IgA u slini metodom radijalne imunodifuzije. Utvrđeno je da koncentracije mikroelemenata variraju u zubima ovisno o koncentraciji u vodi. U području s najvišim karijes indeksom nađena je i najviša koncentracija bakra. Koncentracija stroncija u zubnim tkivima bila je u direktnoj ovisnosti o koncentraciji u pijućoj vodi. Uz nižu raširenost karijesa utvrđena je viša koncentracija fluora i stroncija u pijaćoj vodi i zubnom tkivu. Nivo IgA nije pokazao značajne varijacije u ispitanika s različitim intenzitetom karijesa.The effects of plaque, some microelements (copper, iron, lead, fluor and strontium) and IgA on the incidence of dental caries in three regions of Serbia have been investigated. The microelement content of drinking water and of hard dental tissues has been determined by the method of atomic absorption, and salivary IgA by the method of radial immunodiffusion. It has been established that the microelement concentration in the teeth depended on their concentrations in water. In the region with the highest caries index the highest copper concentration was found. The strontium concentration in dental tissues was directly proportionale to its concentration in drinking water. Lower incidence of dental caries was found with higher concentrations of fluor and strontium in drinking ater and dental tissues. The differences in IgA concentrations were not found to pairalel the differences in the prevalence of caries to any significant extent

Gutzwiller wavefunction in the three-band Hubbard model: A variational Monte Carlo study

The Gutzwiller wave function for the three-band Hubbard model on a two dimensional CuO$_2$ plane is studied by using the variational Monte Carlo (VMC) method in the limit $U_d \to \infty$, where $U_d$ is the Coulomb repulsion between holes on a Cu site. The VMC results for the energy and the fraction of $d$-holes are compared with those of the Rice-Ueda type Gutzwiller approximation (GA). The difference between the VMC and the GA results are most pronounced at half-filling, and away from half-filling the two results agree well in both the hole-doped and the electron-doped cases. The doping dependence of the momentum distribution function is also studied.Comment: 18 pages (RevTeX), 8 figures (postscript) appended, for remaining 5 figures contact [email protected]

Stable population structure in Europe since the Iron Age, despite high mobility

Ancient DNA research in the past decade has revealed that European population structure changed dramatically in the prehistoric period (14,000–3000 years before present, YBP), reflecting the widespread introduction of Neolithic farmer and Bronze Age Steppe ancestries. However, little is known about how population structure changed from the historical period onward (3000 YBP - present). To address this, we collected whole genomes from 204 individuals from Europe and the Mediterranean, many of which are the first historical period genomes from their region (e.g. Armenia and France). We found that most regions show remarkable inter-individual heterogeneity. At least 7% of historical individuals carry ancestry uncommon in the region where they were sampled, some indicating cross-Mediterranean contacts. Despite this high level of mobility, overall population structure across western Eurasia is relatively stable through the historical period up to the present, mirroring geography. We show that, under standard population genetics models with local panmixia, the observed level of dispersal would lead to a collapse of population structure. Persistent population structure thus suggests a lower effective migration rate than indicated by the observed dispersal. We hypothesize that this phenomenon can be explained by extensive transient dispersal arising from drastically improved transportation networks and the Roman Empire’s mobilization of people for trade, labor, and military. This work highlights the utility of ancient DNA in elucidating finer scale human population dynamics in recent history
