Land degradation on barren hills: A case study in northeast Vietnam
(Springer, New York, 2008)
The term "barren hills" has been a keyword for land degradation in the uplands of Vietnam for over a decade. Nevertheless, the "barren" land is still not adequately ecologically characterized. In this work, we analyze land ...
Glucocorticoid excess and disturbed hemodynamics in advanced age: the extent to which soy isoflavones may be beneficial
(General Physiol And Biophysics, Bratislava, 2012)
Advanced age is often accompanied by glucocorticoid excess which contributes to the pathogenesis of the metabolic syndrome associated with some hemodynamic disorders. Impaired central regulation of stress hormones secretion ...
A phenomenological analysis of sintering kinetics from the viewpoint of activated volume
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2005)
The sintering kinetics of real systems has been viewed as a process of transport of activated volume. Activated volume is a parameter that can be used to describe mass transport during the sintering process. It defines the ...
Color properties of movement detectors in the carassius gibelio (bloch, 1782) tectum opticum studied by selective stimulation of different cone types
(Srpsko biološko društvo, Beograd, i dr., 2009)
Starosne promene u sadržaju insulin - sličnom faktora rasta i u mozgu pacova / Age-related changes in the content of insulin: Like growth factor-l in rat brain
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2002)
Vršena su istraživanja insulinu sličnog faktora rasta (IGF-I) na mišićno i koštano tkivo, ali je posvećena mala pažnja efektu na mozak u toku starenja. Mi smo ispitivali sadržaj IGF-I u moždanom tkivu pacova različite ...
Spontaneous ultraweak, bioluminescence in plants: Origin, mechanisms and properties
(R and D print, 1998)
An analysis of theoretical knowledge and experimental results of ultraweak luminescence (UWL) is provided. The role of excited state of molecules and free radicals, formed in various biochemical reactions, in UWL is ...
Seasonal variations of microbiological parameters of water quality of the Velika Morava river Serbia
(Srpsko biološko društvo, Beograd, i dr., 2012)
In this study, we investigated the level of sanitary pollution and organic contamination of the Velika Morava River, the largest river in central Serbia. Samples of water for microbiological analysis were collected at 5 ...
Electrical properties of ZnO varistors prepared by direct mixing of constituent phases
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Varistor samples containing different amounts of constituent phases were prepared by direct mixing of constituent phases. Detailed electrical characterization was performed to explain the influence of minor phases (spinel ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
(Springer Heidelberg, Heidelberg, 2008)
A single p-type crystal of the mineral, pyrite ( FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic ( PA) amplitude and phase spectra were measured using a specially ...
Infrared properties of sintered alpha-MnSe
(Carl Hanser Verlag, Munich, 2006)
Far-infrared reflection spectra of sintered alpha-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak ...
