Seasonal variations of microbiological parameters of water quality of the Velika Morava river Serbia
(Srpsko biološko društvo, Beograd, i dr., 2012)
In this study, we investigated the level of sanitary pollution and organic contamination of the Velika Morava River, the largest river in central Serbia. Samples of water for microbiological analysis were collected at 5 ...
Glucocorticoid excess and disturbed hemodynamics in advanced age: the extent to which soy isoflavones may be beneficial
(General Physiol And Biophysics, Bratislava, 2012)
Advanced age is often accompanied by glucocorticoid excess which contributes to the pathogenesis of the metabolic syndrome associated with some hemodynamic disorders. Impaired central regulation of stress hormones secretion ...
Gradient analysis reveals a copper paradox on floodplain soils under long-term pollution by mining waste
(Elsevier, Amsterdam, 2012)
Arable alluvial soils are a globally important resource under increasing pressure from both industrial pollution and intensified agricultural land use. Quality of agricultural soils is ultimately defined by crop yields; ...
Evaluation of the composition and morphology of a WTi/Si system processed by a picosecond laser
(Korean Inst Metals Materials, Seoul, 2012)
In this work we studied the influence of laser radiation on the composition, structure and morphology of WTi thin films deposited on n-type (100) silicon wafers. The films were deposited by d.c. sputtering from a 70:30 at% ...
Further study on fructooligosaccharides of Rhodobryum ontariense
(Adac-Cryptogamie, Paris, 2012)
The identification of nystose and 1(F)-beta-fructofuranosylnystose in the oligosaccharide-rich fraction of the moss Rhodobryum ontariense (Kindb.) Kindb. (Bryaceae) by thin layer chromatography and high pressure chromatography ...
Inappropriately chelated iron in the cerebrospinal fluid of amyotrophic lateral sclerosis patients
(Informa Healthcare, London, 2012)
ALS is characterized by oxidative damage in the brain and cerebrospinal fluid, which is exerted by pro-oxidative activity of iron. Such activity of iron can be drastically increased in the presence of inappropriate iron ...
Determination of kinetic parameters for the hydrogen evolution reaction on the electrodeposited Ni-MoO2 composite coating in alkaline solution
(Elsevier Science Sa, Lausanne, 2012)
As a result of research on the non-noble metal-based composite electrocatalysts for the hydrogen evolution reaction (HER), the Ni-MoO2 composite coating was produced by electrodeposition from an NH4Cl and NiCl2 containing ...
Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solution. Chemical composition, phase composition and morphology effects
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work the hydrogen evolution reaction (HER) onto Ni-Sn alloy coatings deposited at different current densities from the bath containing 0.1 M Sn2+ and 0.1 M Ni2+ ions in the pyrophosphate-glycine solution, was ...
Service life test of non-noble metal composite cathodes for hydrogen evolution in sodium hydroxide solution
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
In this work polarization characteristics and "service life" test of the non-noble metal composite coatings Ni-MoOx and Ni-MoO2 for hydrogen evolution reaction (HER) in 32 wt.% NaOH at 90 degrees C were investigated and ...
Study of the covalently immobilized amyloglucosidase on macroporous polymer by mathematical modeling of the pH optima
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: A totally new approach has been applied for mathematical modeling of the enzyme activity/pH relationship, for quantification and distribution of enzyme activity in and out of carrier pores. This is a very simple ...
