Population viability analysis and potential of its application to Danube sturgeons
(Srpsko biološko društvo, Beograd, i dr., 2009)
Sturgeon species in the Danube River basin have experienced severe decline. Besides overexploitation, habitat loss, and pollution, they are further endangered by lack of efficient policy and management, as well as by serious ...
A wet-chemical route for the preparation of Ni-BaCe0.9Y0.1O3-delta cermet anodes for IT-SOFCs
(Elsevier, Amsterdam, 2009)
Nano-sized BaCe0.9Y0.1O3 - delta (BCY10) protonic conductor powders were used to prepare Ni-BCY10 cermets for anode-supported intermediate temperature solid oxide fuel cells. A new wet-chemical route was developed starting ...
Seasonal changes in condition, hepatosomatic index and parasitism in sterlet (Acipenser ruthenus L.)
(Scientific Technical Research Council Turkey-Tubitak, Ankara, 2009)
Measurements of biomarker responses in fish from contaminated sites could provide valuable data for environmental risk assessment. Biomarkers are sensitive to both environmental pollution and confounding factors that are ...
Potential role of hydrogen peroxide and melanin in the cold hardiness of Ostrinia nubilalis (Lepidoptera: Pyralidae)
(Czech Acad Sci, Inst Entomology, Ceske Budejovice, 2009)
The aim of this study was to investigate the relationship between antioxidant enzymes and reactive oxygen species production in diapausing larvae of the European corn borer, Ostrinia nubilalis (Lepidoptera: Pyralidae) kept ...
Reproducibility of age determination by scale and vertebra in pontic shad (alosa pontica eichwald, 1838), from the Danube
(Srpsko biološko društvo, Beograd, i dr., 2009)
Specimens of Pontic shad (Alosa pontica Eichwald, 1838) were collected during April and May of 2006 in the Danube River (rkm 863) just downstream of the Iron Gate (Djerdap) II dam. Twenty-eight scales and 30 vertebrae were ...
Labile fractions of soil organic carbon in mollisols from different climatic regions
(Pisa Univ Press, Pisa, 2009)
Characterization of Labile Fractions of Soil Organic Carbon in Mollisols from different climatic regions. The research studied the potential mineralization and characterization of labile SOM of different types of Mollisols: ...
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 ...
A study of magneto-crystalline alignment in sintered barium hexaferrite fabricated by powder injection molding
(Elsevier Science Bv, Amsterdam, 2009)
Barium hexaferrite permanent magnets were produced by powder injection molding. Starting barium hexaferrite powder was prepared from a Fe2O3 and BaCO3 powder mixture by calcination followed by milling. The feedstock for ...
Stability and electronic properties of rhenium sulfide nanotubes
(Wiley-V C H Verlag Gmbh, Weinheim, 2009)
The structural properties, the stability and the electronic properties of single-walled ReS2 nanotubes are studied for-the first time using the density-functional tight-binding method (DFTB). It is found, that the properties ...
Thermal diffusivity of sintered 12CaO x 7Al(2)O(3)
(Springer Heidelberg, Heidelberg, 2008)
The thermal diffusivity and free carrier diffusion coefficient of 12CaO x 7 Al2O3 ( C12A7) sintered for different times in air or hydrogen followed by treatment with UV light were determined from photoacoustic phase and ...
