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 ...
Far infrared properties of sintered NiO
(Elsevier Sci Ltd, Oxford, 2007)
Far infrared reflection spectra of NiO polycrystals sintered at 1100 degrees C for various times (30-240 min) were measured at room temperature using a FTIR Spectrometer-Brucker 113V. The measured spectra depended on the ...
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 ...
A detailed XRD and FTIR analysis of Bi2O3 doped ZnO-SnO2 ceramics
(A Global Road Map for Ceramic Materials and Technologies: Forecasting the Future of Ceramics, Intern, 2008)
ZnO-SnO2 ceramics were prepared with a traditional powder mixed oxide route by mixing starting powders of ZnO and SnO2 in the molar ratio 2:1 and adding small amounts (0.5; 1.0; and 1.5 molar%) of Bi 2O3. These mixtures ...
Morphology and composition of the Fe-Ni powders electrodeposited from citrate containing electrolytes
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposition of the Fe-Ni powders from citrate containing electrolytes for different Ni/Fe ions concentration ratios, using Fe(Ill) and Fe(II) salts at pH 4.5 and pH 4.0 respectively was investigated by the ...
Microstructural characterization of mechanicallyactivated ZnO powders
(Wiley, Hoboken, 2008)
In this paper, changes of microstructural characteristics of disperse systems during mechanical activation of zinc oxide (ZnO) have been investigated. ZnO powder was activated by grinding in a planetary ball mill in a ...
Structural characterization of mechanically milled ZnO: influence of zirconia milling media
(IOP Publishing Ltd, Bristol, 2008)
Zinc oxide nanoparticles were obtained by milling in a planetary ball mill with a zirconia milling assembly for up to 5 h in air. The samples were characterized by scanning electron microscopy, x-ray diffraction (XRD) and ...
Occurrence and Distribution of Grapevine Yellows Caused by Stolbur Phytoplasma in Montenegro
(Wiley, Hoboken, 2009)
In August 2008, grapevine yellows (GY)-like symptoms were observed in vineyards near Podgorica, Montenegro. A survey of the grape growing area of Montenegro was conducted to identify and determine the distribution of ...
The potential of different plant species for nickel accumulation
(Diagnosis Press Ltd, Sofia, 2007)
Contamination of the environment with toxic heavy metals is a mayor environmental problem. Aimed to find effective and economical attractive solutions for environment cleaning, scientists intensively evolve various ...
Far infrared spectroscopy of Pb0.85Sn0.15Te alloy doped with Ni
(Carl Hanser Verlag, Munich, 2008)
Far infrared reflectivity spectra of single crystal Pb0.85Sn0.15Te doped with Ni were measured in the temperature range between 10 K and 300 K. Analysis of the experimental spectra was made using a fitting procedure based ...
