Soil Properties and Trace Elements Contents Following 40 Years of Phosphate Fertilization
(Wiley, Hoboken, 2010)
Long-term application of P fertilizers may eventually result: in excess and/or toxic accumulations of trace elements and microelements in soil. The effect of monoammonium-phosphate (MAP) on basic soil properties (pH, CEC, ...
Effect of chemisorbed CO on MoOx-Pt/C electrode on the kinetics of hydrogen oxidation reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The influence of poisoning of MoOx-Pt catalyst by CO on the kinetics of H-2 oxidation reaction (HOR) at MoOx-Pt electrode in 0 5 mol dm(-3) HClO4 saturated with H-2 containing 100 ppm CO was examined on rotating disc ...
Zinc-induced oxidative stress in Verbascum thapsus is caused by an accumulation of reactive oxygen species and quinhydrone in the cell wall
(Wiley, Hoboken, 2010)
Oxidative stress is one aspect of metal toxicity. Zinc, although unable to perform univalent oxido-reduction reactions, can induce the oxidative damage of cellular components and alter antioxidative systems. Verbascum ...
Liver, gills, and skin histopathology and heavy metal content of the Danube sterlet (acipenser ruthenus linnaeus, 1758)
(Setac Press, Pensacola, 2010)
The sterlet (Acipenser ruthenus L.) is a bottom-feeding fish species with a direct exposure to contaminants from water and sediments. Although heavy metal pollution is believed to be one of the main threats to the sterlet ...
The effects of manganese and copper in vitro and in vivo on peroxidase catalytic cycles
(Elsevier Gmbh, Munich, 2010)
Here we present the results of in vitro and in vivo studies of the influence of Mn2+ and Cu2+ on the peroxidative and oxidative catalytic functions of class III peroxidase. Complex peroxidase catalysis by intermediates ...
Voltammetric and differential pulse determination of roxithromycin
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The oxidative behavior of antibiotic roxithromycin standard was studied at a gold electrode in 0.05 M NaHCO3 using cyclic linear sweep voltammetry and differential pulse voltammetry. It was found that the value of the ...
Characterisation of phenol oxidase and peroxidase from maize silk
(Wiley-Blackwell, Hoboken, 2010)
Silk of some maize genotypes contains a high level of phenolics that undergo enzymatic oxidation to form quinones, which condense among themselves or with proteins to form brown pigments. Two phenolic oxidizing enzymes, ...
An attempt to predict the mechanism of Mo-Ni-O powders electrodeposition from the results of their TEM analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The Mo-Ni-O powders were electrodeposited from ammonium sulfate containing electrolytes with different Mo/Ni ion concentration ratios. The phase composition of these powders was investigated using TEM. EDS and XRD analysis. ...
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 ...
Phytophthora ramorum Occurrence in Ornamentals in Serbia
(Amer Phytopathological Soc, St Paul, 2010)
In a survey to determine the presence of Phytophthora ramorum in Serbia, ornamentals from garden centers, nurseries, and private and public gardens, as well as imported plant material, were inspected. In total, 577 plant, ...
