Ante- and postpartum redox status of blood in women with inherited thrombophilia treated with heparin
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
UV responses of Lolium perenne raised along a latitudinal gradient across Europe: a filtration study
(Wiley, Hoboken, 2012)
Lolium perenne (cv. AberDart) was grown at 14 locations along a latitudinal gradient across Europe (3768 degrees N) to study the impact of ultraviolet radiation (UV) and climate on aboveground growth and foliar UV-B absorbing ...
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 ...
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% ...
Far infrared study of local impurity modes of Boron-doped PbTe
(Springer, New York, 2012)
PbTe single crystals, doped with B, were grown using the Bridgman method. Far infrared spectra were measured in the temperature range between 10 K and room temperature. The experimental spectra were numerically analyzed, ...
Involvement of Na+/K(+)pump in fine modulation of bursting activity of the snail Br neuron by 10 mT static magnetic field
(Springer, New York, 2012)
The spontaneously active Br neuron from the brain-subesophageal ganglion complex of the garden snail Helix pomatia rhythmically generates regular bursts of action potentials with quiescent intervals accompanied by slow ...
The reaction of methionine with hydroxyl radical: reactive intermediates and methanethiol production
(Springer Wien, Wien, 2012)
The mechanisms of reaction of methionine with hydroxyl radical are not fully understood. Here, we unequivocally show using electron paramagnetic resonance spin-trapping spectroscopy and GC-FID and GC-MS, the presence of ...
