Effects of acute cooling on fish electroretinogram: A comparative study
(Elsevier Science Inc, New York, 2015)
Temperature dependence of electroretinogram (ERG) was investigated in 3 fish species occupying different habitats - dogfish shark (Scyliorhinus canicula), Prussian carp (Carassius gibelio) and European eel (Anguilla ...
Synthesis of Anatase Nanopowders by Sol-gel Method and Influence of Temperatures of Calcination to Their Photocatalitic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor, varying the temperature of calcination (from 500 to 550 degrees C with the step of 10 degrees C). XRPD ...
Hydrothermally assisted synthesis of YMnO3
(Elsevier Sci Ltd, Oxford, 2015)
In this work single phase hexagonal YMnO3 powders were prepared starting from Y(CH3COO)(3)center dot xH(2)O, Mn(CH3COO)(2)center dot 4H(2)O, KMnO4 and KOH using methods of conventional (280 degrees C for 6 h) or microwave ...
The effects of wild-type and mutant sod1 on smooth muscle contraction
(Srpsko biološko društvo, Beograd, i dr., 2015)
In this work we compared the mutated liver copper zinc-containing superoxide dismutase (SOD1) protein G93A of the transgenic rat model of familial amyotrophic lateral sclerosis (FALS), to wild-type (WT) rat SOD1. We examined ...
New data on sterlet (acipenser ruthenus l.) Genetic diversity in the middle and lower danube sections, based on mitochondrial dna analyses
(Društvo genetičara Srbije, Beograd, 2015)
