Uticaj ledenih doba na filogeografske obrasce šumskih ptica: Phylloscopus collybita, Prunella modularis i Certhia familiaris / Impact of ice ages on phylogeographic patterns of forest bird species: Phylloscopus collybita, Prunella modularis and Certhia familiaris
(Univerzitet u Beogradu, Biološki fakultet, 2018)
izolaciju populacija u refugijumima za vreme glacijalnih maksimuma, i nakon toga rekolonizaciju šireg dela Evropskog kontinenta za vreme povlačenja lednika. Da bi se ova paradigma testirala, analizirani su filogenetski ...
Effects of the static and ELF magnetic fields on the neuronal population activity in Morimus funereus (Coleoptera, Cerambycidae) antennal lobe revealed by wavelet analysis
(Elsevier Science Inc, New York, 2015)
To study the influence of a static magnetic field (SMF, 2 mT) and extremely low frequency magnetic field (ELF MF, 50 Hz, 2 mT) on the neuronal population activity, the experiments were performed on adult longhorn beetles ...
A new electrolyte based on Tm3+-doped delta-Bi2O3-type phase with enhanced conductivity
(Elsevier Science Bv, Amsterdam, 2015)
The possibility to stabilize the delta-Bi2O3-type polymorph with high ionic conductivity by doping with Tm2O3 was investigated in this study. Five microaystalline samples were synthesized at 750 degrees C from alpha-Bi2O3 ...
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 ...
Structural, ferroelectric and magnetic properties of BiFeO3 synthesized by sonochemically assisted hydrothermal and hydro-evaporation chemical methods
(Elsevier Sci Ltd, Oxford, 2016)
BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. ...
The Negative Effect of Soy Extract on Erythrocyte Membrane Fluidity: An Electron Paramagnetic Resonance Study
(Springer, New York, 2011)
A decrease of erythrocyte membrane fluidity can contribute to the pathophysiology of hypertension. Soy products, which are used as alternative therapeutics in some cardiovascular conditions, contain various isoflavones ...
Macronutrient contents in the leaves and fruits of red raspberry as affected by liming in an extremely acid soil
(Czech Academy Agricultural Sciences, Prague, 2015)
The study evaluates the effect of liming materials application in combination with NPK fertilizer and borax on macronutrient contents (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg)), in an ...
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 ...
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 ...
Uticaj rastvora amonijum-nitrata i natrijum-sulfata na mehanička svojstva i strukturu geopolimera na bazi elektrofilterskog pepela termoelektrana / Effects of ammonium nitrate and sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2015)
Geopolimeri na bazi tri različita uzorka elektrofilterskog pepela izloženi su dejstvu koncentrovanog rastvora NH4NO3 (480 g/dm3) i rastvora Na2SO4 (50 g/dm3) u periodu od 18 meseci. Promene mehaničkih svojstava geopolimera ...
