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% ...
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 ...
Relevance of the ability of fructose 1,6-bis(phosphate) to sequester ferrous but not ferric ions
(Elsevier Sci Ltd, Oxford, 2011)
The cytoprotective activity of F16BP has been documented in severe conditions such as convulsions, reperfusion injury, septic shock, diabetic complications, hypothermia-induced injury, UV-provoked skin damage and in other ...
A Thermal Sensor for Water Using Self-Heated NTC Thick-Film Segmented Thermistors
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2011)
A simple thermal (heat loss) sensor system was designed in a small plastic tube housing using a negative thermal coefficient (NTC) thick-film thermistor as a self-heating sensor. The voltage power supply [range constant ...
Magnetic properties of doped LaMnO3 ceramics obtained by a polymerizable complex method
(Springer, Dordrecht, 2010)
Substituted lanthanum manganites with the general formula A(1-x) B (x) MnO3 (A = La, B = Ca, SraEuro broken vertical bar) have attracted a lot of attention due to their exceptional electric and magnetic properties. In this ...
Raman study of structural disorder in ZnO nanopowders
(John Wiley & Sons Ltd, Chichester, 2010)
Raman scattering spectroscopy has been used for the characterization of zinc oxide nanoparticles obtained by mechanical activation in a high-energy vibro-mill and planetary ball mill. Raman modes observed in spectra of ...
Antioxidant activity of small grain cereals caused by phenolics and lipid soluble antioxidants
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
In this study, the content of soluble, free forms of phenolic compounds (total phenolics, flavonoids, PVPP (polyvinylpolypyrrolidone) bound phenolics, proanthocyanidins and phenolic acids), as well as the content of ...
Solvothermal syntheses of nano- and micro-sized ZnO powders with a controllable morphology
(Springer, Dordrecht, 2012)
Zinc oxide powders with different morphologies and grain sizes were synthesized using solvothermal methods from ethanolic zinc acetate solutions in the presence of lithium hydroxide. The influence of the temperature and ...
