Antioxidant activity of propolis extracts from Serbia: A polarographic approach
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Antioxidant activity (AO) of commercial propolis extracts (PEs), available on Serbian market, was determined by direct current (DC) polarography. Polarographic anodic current of 5.0 mmol L-1 alkaline solution of H2O2 was ...
In situ bioremediation of sediment contaminated with mineral oil / In situ bioremedijacija sedimenta kontaminiranog mineralnim uljem
(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
Zagađenje vode, zemljišta i sedimenta naftom i njenim derivatima, može se javiti tokom eksploatacije, transporta i skladištenja i predstavlja rizik za životnu sredinu i ljudsko zdravlje. Bioremedijacija je zelena tehnologija ...
Anticancer potential of new steroidal thiazolidin-4-one derivatives. Mechanisms of cytotoxic action and effects on angiogenesis in vitro
(Oxford : Pergamon-Elsevier Science Ltd, 2017)
The synthesis and cytotoxic activities determination of new steroidal mono- and bis(thiazolidin-4-ones) 4a-f and 5a-f have been performed. Their anticancer action was also evaluated in comparison to previously synthesized ...
Studying of liquid thermolysis products of various types of immature kerogen in sedimentary lacustrine rocks from the valjevo-Mionica basin, Serbia, and the effect of Pt4+ and Ru3+ ions on their yield and the hydrocarbon composition
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Liquid thermolysis products of various types of immature kerogen from sedimentary lacustrine rocks from the Valjevo-Mionica basin in Serbia were studied to evaluate the generation potential of kerogen contained in the ...
Improvement of the stoichiometric network analysis for determination of instability conditions of complex nonlinear reaction systems
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
Stoichiometric network analysis (SNA), a known method for analyzing complex reaction systems including biochemical ones, is improved and applied to a nonlinear process studied far from equilibrium in a continuously fed, ...
Two structurally distinct chalcone dimers from Helichrysum zivojinii and their activities in cancer cell lines
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Dimers tomoroside A (1) and tomoroside B (2) of the co-occuring known chalcone monomer (3), along with the seven known flavonoid glucosides (4-10), were isolated from the aerial parts of Helichrysum zivojinii Cernjavski & ...
Applicability of Calculated Vitrinite Reflectance for Assessment of Source Rock's Organic Matter Maturity in Hyperthermal Basins (Banat Depression, Serbia)
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Middle and Upper Miocene petroleum source rocks from the Banat Depression, SE Pannonian Basin (Serbia) were investigated. These rocks contain organic matter (OM) in a relatively wide range of maturity (from early to late ...
Analysis of the composite and film hardness of electrodeposited nickel coatings on different substrates
(Elsevier Science Sa, Lausanne, 2008)
Fine-grained nickel thin films were electrodeposited from a self-made sulphamate-based electrolyte on different substrates: polycrystalline cold-rolled copper and single crystal silicon with two different orientations, ...
A model for introducing strategies in sustainable development of small-scale enterprises in Serbia
(University of Novi Sad, Technical faculty Mihajlo Pupin, Zrenjanin, 2015)
This paper presents the algorithm for introducing the strategies ensuring the sustainable development of enterprises, but also provides improvement of small-scale manufacturing process. Three strategies are given in the ...
Alternating catalytic reactions
(Springer, 2019)
The application of alternating current is advantageous in energy transfer over long distances. It is a well-known fact now, but subject of long conflict in the era of pioneering works in electric power production. There ...
