Evaluation of antioxidant capacity of Allium ursinum L. volatile oil and its effect on membrane fluidity
(Elsevier Sci Ltd, Oxford, 2008)
A total of 20 components were identified in Allium ursinum volatile oil (AUVO) by GC-MS, and 10 of them are found for the first time in this plant species. The antioxidant capacity of AUVO was examined by beta-carotene-linoleic ...
Spectral and fractal analysis of cerebellar activity after single and repeated brain injury
(Springer, New York, 2008)
The cerebellum, even when not directly damaged, is potentially interesting for understanding the adaptive responses to brain injury. Cerebellar electrocortical activity (ECoG) in rats was studied using spectral and fractal ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H-2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm(-3) HClO4, saturated with H-2 containing 100 ppm CO, was examined with rotating ...
Microstructure of LaNiO3 thin films obtained by the spin-on technique from citrate precursors
(Elsevier Sci Ltd, Oxford, 2008)
The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from ...
Concentrations of heavy metals in soil and leaves of plant species Paulownia elongata SYHu and Paulownia fortunei Hemsl
(Academic Journals, Victoria Island, 2009)
This paper sums up the results of the research on heavy metals contents (Pb, Ni, Fe, Zn and Mn) in soil and leaves of the plant species, Paulownia elongata S.Y. Hu and Paulownia fortunei Hemsl. at the plantation established ...
Star-shaped oligobenzoates: Non-conventional mesogens forming columnar helical mesophases
(Wiley-V C H Verlag Gmbh, Weinheim, 2008)
Star-shaped mesogens with a phloroglucinol or a trimesic acid core and oligobenzoate arms with up to five repeating units have been synthesised. non-conventional mesogens form various columnar mesophases over a broad ...
Characterization of electrodeposited Cd-Co alloy coatings by anodic linear sweep voltammetry
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposited Cd-Co alloys were characterized by the anodic linear sweep voltammetry (ALSV) technique in the solution of 1 M NaCl (pH 2). It is shown that Cd-Co alloys could be deposited with high current efficiency ...

In Europe Phytophthora ramorum has been reported on a range of
ornamentals as well as on a limited number of tree species in at least in 11
countries: UK, Spain, Belgium, Germany, the Netherlands, Italy, France,
Switzerland, ...
Oxygen and light accelerate recovery from SO2-induced inhibition of leaf photosynthesis and from cytoplasmic acidification
(Elsevier GmbH, 2000)
Leaves of several plant species were illuminated either in air or in a gas atmosphere with reduced oxygen content, and photosynthesis and transpiration were recorded after brief exposure to high concentrations of SO2. ...
Are leaf hydrogen peroxide concentrations commonly overestimated? The potential influence of artefactual interference by tissue phenolics and ascorbate
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2002)
We have examined the authenticity of two methods for determination of H2O2 in leaf tissue. We show that the high concentrations of ascorbic acid present in leaf extracts interfere with both techniques. In the chromogenic ...
