Assessment of extinction risk and reasons for decline in sturgeon
(Springer, Dordrecht, 2006)
Sturgeon populations in the Danube River have been affected by a combination of hydropower development, over-harvesting, habitat degradation from agricultural and industrial practices and from urbanization. The effects of ...
Activity and stability of soluble and immobilized alpha-glucosidase from baker's yeast in cosolvent systems
(Taylor & Francis Ltd, Abingdon, 2006)
The activity of alpha-glucosidase from baker's yeast was determined in various concentrations of dioxan, tetrahydrofuran, tert-butanol, dimethylformamide, methanol and dimethylsulfoxide (DMSO). Higher activities were ...
Magneli phase titanium oxides as catalyst support - Electrochemical behavior of Ebonex/Pt catalysts
(Journal of New Materials for Electrochemical Systems, 2006)
The impregnation method has been applied to synthesize platinum nanoparticles on Magneli phase titanium oxide powder (Ebonex). Surface area of the Ebonex support was determined by BET technique. Distribution and morphology ...
Capacity of cerebrospinal fluid to transform hydrogen peroxide-relation to neurodegenerative changes in ALS
(Taylor & Francis Ltd, Abingdon, 2006)
Fenton reaction produces hydrogen radical (center dot H) in chemical and biological systems
(Taylor & Francis Ltd, Abingdon, 2006)
Temperature dependence of fractal dimension of grain boundary region in SnO2 based ceramics
(Springer, New York, 2006)
Fractal dimensions of grain boundary region in doped SnO2 ceramics were determined based on previously derived fractal model. This model considers fractal dimension as a measure of homogeneity of distribution of charge ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Elsevier Science Sa, Lausanne, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
Phenolics, lignin content and peroxidase activity in Picea omorika lines
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2006)
We analyzed low molecular mass phenolics, lignin content and both soluble and cell wall bound peroxidase activity in the needles of three Picea omorika (Pancic) Purkyne lines grown in the generative seed orchard. The highest ...
