Assessment of Fish Stocks and Elemental Pollution in the Danube, Sava and Kolubara Rivers on the Territory of the City of Belgrade, Serbia
(Bulgarian Academy of Sciences, 2014)
There is a lack of adequate estimates of the fish stocks in the Belgrade city area, Serbia, as well as of the current fishery pressure on fish diversity and of the contamination level of fish meat. These factors obstruct ...
Biotic Typology of the Danube River Based on Distribution of Mollusc Fauna as Revealed by the Second Joint Danube Survey (2007)
(Bulgarian Academy of Sciences, 2014)
The aim of this study is to present the distribution of aquatic molluscs along a 2600 km long stretch of the Danube River based on information obtained during the Second Joint Danube Survey (JDS2) in 2007. The collected ...
Effect of long-term cyanide exposure on cyanide-sensitive respiration and phosphate metabolism in the fungus phycomyces blakesleeanus
(Srpsko biološko društvo, Beograd, i dr., 2014)
The effects of long-term exposure (5 h) of Phycomyces blakesleeanus mycelium to 5 mM KCN on respiration and phosphate metabolites were tested. Exposure to cyanide, antimycin A and azide lead to a decrease in the activity ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
Biomonitoring and Genetic Analysis of Sturgeons in Serbia: A Contribution to Their Conservation
(Bulgarian Academy of Sciences, 2014)
While the historical sturgeon catch in Serbia encompassed mainly four species (beluga sturgeon - Huso huso, Russian sturgeon - Acipenser gueldenstaedtii, stellate sturgeon - Acipenser stellatus, and sterlet - A. ruthenus) ...
Characterization of the Alkoxide-based Sol-gel Derived La9.33Si6O26 Powder and Ceramic
(Slovensko Kemijsko Drustvo, Ljubljana, 2014)
In this study, we report on the acid-catalysed synthesis of La9.33Si6O26 from lanthanum nitrate or acetate and silicon ethoxide (TEOS) in the ethanol solvent, upon the transition from liquid to amorphous and crystalline ...
Further in vitro evaluation of antiradical and antimicrobial activities of phytol
(Taylor & Francis Ltd, Abingdon, 2014)
The antiradical activity of phytol was evaluated by electron paramagnetic resonance towards hydroxyl radical (root OH), superoxide anion radical (), methoxy radical (root CH2OH), carbon-dioxide anion radical (), as well ...
Composition and diversity of ichthyoplankton in the Boka Kotorska Bay (South Adriatic Sea)
(Inst Oceanografiju I Ribarstvo, Split, 2014)
Variation in the diversity of ichthyoplankton was analyzed from samples collected during threeyear cycle in Boka Kotorska Bay. Samples were collected using Calvet (modified PairOVET) plankton net at 18 stations, from July ...
Hydro- and solvothermally-prepared ZnO and its catalytic effect on the photodegradation of Reactive Orange 16 dye
(Srpsko hemijsko društvo, Beograd, 2014)
In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, ...
Further in vitro evaluation of cytotoxicity of the marine natural product derivative 4 '-leucine-avarone
(Taylor & Francis Ltd, Abingdon, 2014)
The cytotoxicity of 4-leucine-avarone, amino derivative of the sponge Dysidea avara secondary metabolite avarone, was evaluated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide assay in vitro against seven ...
