Ecological status of Serbian rivers based on an ichthyological assessment
(Vasile Goldis Western University, Arad, 2011)
Anthropogenic influences on fish populations in river ecosystems can be studied at the individual level, as well as through the assessment of fish fauna composition. This study presents research that was focused at the ...
Ecologically acceptable usage of derivatives of essential oil of sweet basil, Ocimum basilicum, as antifeedants against larvae of the gypsy moth, Lymantria dispar
(Library of the University of Arizona, 2013)
Ethanol solutions of five fractions obtained from essential oil of sweet basil Ocimum basilicum L. (Lamiales: Lamiaceae) (F1-F5) were tested for their antifeedant properties against 2nd instar gypsy moth larvae, Lymantria ...
Nest-site preference of griffon vulture (gyps fulvus) in Herzegovina
(Srpsko biološko društvo, Beograd, i dr., 2012)
Although formerly an abundant species, the Eurasian Griffon (Gyps fulvus Hablizl, 1783) has undergone a dramatic decline in Herzegovina. Such an unfavorable trend may be associated with frequent poisoning incidents ...
Electrodeposition and characterization of Ni-MoO2 composite coatings as cathodes for the hydrogen evolution reaction in alkaline solution
(Srpsko hemijsko društvo, Beograd, 2013)
Composite Ni-MoO2 coatings were prepared and characterized with respect to their possible application as electrocatalysts for the hydrogen evolution reaction (HER) in alkaline solution. The composites were electrodeposited ...
New record of neogobius fluviatilis (pallas, 1814) (gobiidae) in the Danube river basin (Serbia)
(Srpsko biološko društvo, Beograd, i dr., 2013)
Recently, the growing colonization of allochthonous organisms in the Serbian section of the Danube River and interconnected ecosystems was observed. Hydro-morphological changes, such as regulations of the watercourse, have ...
Heavy Metal Accumulation and the Genotoxicity in Barbel (Barbus barbus) as Indicators of the Danube River Pollution
(Hindawi Ltd, London, 2012)
The aim of this study was to analyze 16 trace elements (Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, and Zn) in different barbel (Barbus barbus) tissues and to detect the presence of genotoxic effects in ...
Mechanical Characterization of Ink-Jet Printed Ag Samples on Different Substrates
(Springer New York LLC, 2013)
In this paper, the main activity was to investigate how different substrates, temperature of sintering and percentage of silver ink containing silver nanoparticles influence on Young's modulus and hardness of printed silver ...
Vanadate Influence on Metabolism of Sugar Phosphates in Fungus Phycomyces blakesleeanus
(Public Library Science, San Francisco, 2014)
The biological and chemical basis of vanadium action in fungi is relatively poorly understood. In the present study, we investigate the influence of vanadate (V5+) on phosphate metabolism of Phycomyces blakesleeanus. ...
Spatial distribution of soil pollutants in urban green areas (a case study in Belgrade)
(Elsevier Science Bv, Amsterdam, 2018)
On the kinetics of the hydrogen evolution reaction on Ni-MoOx composite catalysts in alkaline solutions
(Srpsko hemijsko društvo, Beograd, 2012)
MoO3 particles were co-deposited with Ni onto smooth or rough Ni supports from modified Watt baths of different compositions. Morphology and composition of the electrodeposits were characterized by means of cyclic voltammetry, ...
