Populaciona dinamika i ekotoksikologija crnog američkog patuljastog soma (Ameiurus melas Rafinesque, 1820) u Savskom jezeru / Population dynamic and and ecotoxicology of the black bullhead (Ameiurus melas Rafinesque, 1820) in Sava Lake
(Univerzitet u Beogradu, Biološki fakultet, 2015)
Crni američki patuljasti som (Ameiurus melas Rafinesque, 1820) je najzastupljenija i najuspešnija alohtona vrsta ribe koja naseljava kopnene vode Evrope. Istraživanja koja su sprovedena u proteklih nekoliko godina ukazuju ...
Ekogenotoksikološka procena kvaliteta površinskih voda komet testom na različitim tkivima klena (Squalius cephalus L.) / Ecogenotoxicological evaluation of surface water quality with comet assay on different tissues of european chub (Squalius cephalus L.)
(Univerzitet u Beogradu, Biološki fakultet, 2016)
Intenzivni procesi proizvodnje i oslobađanje velikog broja hemijskih agenasa, kao i metala u spoljašnju sredinu, najvećim delom u rečne tokove, dovela je do potrebe za primenom testova koji će detektovati njihov genotoksični ...
Toksičnost i biološki uticaj nanočestica cerijum-oksida obloženih ugljenim hidratima na odabrane model organizme / Toxicity and biological effect of cerium-oxide nanoparticles coated with carbohydrates on selected model organisms
(Univerzitet u Beogradu, Hemijski fakultet, 2020)
Nanočestice cerijum-oksida (nCeO2) su nanomaterijal popularan zbog izmene Ce3+ i Ce4+ oksidacionih stanja. Međutim, niska stabilnost i taloženje nCeO2 u vodenoj sredini predstavljaju ograničenje njihovoj raznovrsnoj primeni. ...
Magnetna i električna svojstva keramičkih kompozitnih materijala na bazi nikl-cink-ferita i barijum-titanata dobijenih postupkom auto-sagorevanja / Magnetic and electric properties of ceramic composite materials based on nikel-zinc ferrite and barium titanate obtained by the auto-combustion route
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2017)
U ovoj doktorskoj disertaciji ispitivana su magneto-električna svojstva kompozitnih materijala koji se sastoje od magnetne faze, nikl-cink ferita, i feroelektrične faze, barijum titanata u razlicitim masenim odnosima. ...
The European Chub (Squalius cephalus) as an indicator of reservoirs pollution and human health risk assessment associated with its consumption
(Pergamon, 2022)
Five reservoirs (Vlasina, Medjuvršje, Zaovine, Perućac, and Garaši) in Serbia were chosen as study sites, which differ by their position, purpose, stages of eutrophication, management policies, and levels of anthropogenic ...
Determination of the sources of nitrate and the microbiological sources of pollution in the Sava River Basin
(Elsevier, Amsterdam, 2016)
Coupled measurements of nitrate (NO3-), nitrogen (N), and oxygen (O) isotopic composition (delta N-15(NO3) and delta O-18(NO3)) were used to investigate the sources and processes of N cycling, while the microbial source ...
Influence of Processing Method on Dielectric Properties of BaBi4Ti4O15 Ceramics
(COST MPO9O4: Single- and multiphase ferroics and multiferroies with restricted geometries (SIMUFER) Closing Conference and Final Management Committee Meeting, CNR-lENl: Institute for Energetics and lnterphases, Genoa, ltaly 30th January -'1st February, 2014, 2014)
Bismuth layer-structured ferroelectrics (BLSF), first described by Aurivillius, have attracted much
attention for their application in non-volatile random access memory and high temperature piezoelectric
devices. BaBi4Ti4O15 ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Elsevier Science Sa, Lausanne, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
Evaluation of kinetic data for crystallization of TiO2 prepared by hydrolysis method
(Springer, Dordrecht, 2000)
The formation of TiO2 prepared by hydrolysis method was presented. Thermodynamics and kinetics of anatase crystallization reaction were investigated. Differential method of kinetic data evaluation in non-isothermal conditions ...
Grain growth during sintering of batio3 with lif
(Taylor & Francis Ltd, Abingdon, 1996)
The sintering behavior of BaTiO3 with LiF showed that it was possible to sinter barium titanate at temperatures below 1000 degrees C. Different combinations of the sintering powders were prepared by adding 1 to 5 w% LiF ...
