Removal of N-terminal peptides from β-lactoglobulin by proteolytic contaminants in a commercial phenol oxidase preparation
(International Dairy Journal, 2009)
The use of enzymes may improve the functional properties of various food ingredients. The aim of this study was to examine the effects of proteolytic contaminants in phenol oxidases on β-lactoglobulin (BLG). In the presence ...
Intramolecular MLOH/π and MLNH/π interactions in crystal structures of metal complexes
(Versita, Warsaw, 2009)
Intramolecular metal-ligand OH/π (MLOH/π) and metal-ligand NH/π (MLNH/π) interactions in transition metal complexes between aqua or ammine ligand and ligand containing a C6-aromatic ring were investigated in crystal ...
Speciation of heavy metals in geological matter of the Serbian national parks, protected areas and cities within the Danube river basin after the war conflict in 1999
(Handbook of Environmental Chemistry, Volume 3: Anthropogenic Compounds, 2009)
In order to assess the effects of the 1999 NATO bombing of Serbia on the environment, some of the most widespread and feared pollutants, including heavy metals were determined in various sediment samples that were taken ...
pH-Dependent Leaching of Dump Coal Ash-Retrospective Environmental Analysis
(Taylor & Francis Inc, Philadelphia, 2009)
Trace and major elements in coal ash particles from dump of "Nikola Tesla A" power plant in Obrenovac near Belgrade (Serbia) can cause pollution, due to leaching by atmospheric and surface waters. In order to assess this ...
Activity of polymer supported cobalt catalyst in the Bray-Liebhafsky oscillator
(Maik Nauka/Interperiodica/Springer, New York, 2009)
The infuence of poly-4-vinylpyridine-co-divinylbenzene-Co2+ catalyst on the Bray-Liebhafsky (BL) oscillator used as the matrix for establishing catalyst's activity was analyzed. The addition of the catalyst do not change ...
Evaluation of Hypericum perforatum oil extracts for an antiinflammatory and gastroprotective activity in rats
(Phytotherapy Research, 2009)
Oil extracts of Hypericum perforatum L. (Oleum Hyperici) were prepared in three different ways according to the prescriptions from traditional medicine. Variability of constituents and biological activity were evaluated ...
Large deviation spectra of chaotic time series from Bray-Liebhafsky reaction
(Maik Nauka/Interperiodica/Springer, New York, 2009)
We applied multifractal analysis on time series obtained by deterministic simulation of the Bray-Liebhafsky oscillatory reaction. Large deviation spectrum was used to represent multifractal properties of the attractor. We ...
5,10:13,14-Disecosteroids: novel modified steroids containing 10- and 9-membered rings
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
In this paper a synthetic pathway to the modified 5,10:13,14-bisfragmentation cholestane derivatives 8-14 is described. The synthesis involves introduction of the 5α- and 14α-hydroxyl groups in the cholestane molecule and ...
Promotional effect of Sn-ad on the ethanol oxidation at Pt3Sn/C catalyst
(Elsevier Science Inc, New York, 2009)
Oxidation of ethanol was studied at Sn-ad modified and unmodified Pt3Sn/C and Pt/C catalysts. Pt3Sn/C and Pt/C catalysts were characterized by XRD. Potentiodynamic and chronoamperometric measurements were used to establish ...
Molecular mechanics description of the stabilized effects in (ethylenediamine-N,N '-diacetato)chromate(III) dinuclear complex bridged by pyrazole-3,5-dicarboxylate: DFT calculations of magnetic properties
(Elsevier, 2009)
The mononuclear chromium(III) complex containing quadridentate ligand ethylenediamine-N,N'-diacetate (edda) and the corresponding dinuclear complex bridged by pyrazole-3,5-dicarboxylate (pzdc) are investigated by molecular ...
