Kinetics of the alpha-beta Phase Transformation in Seeded Si3N4 Ceramics
(Science of Sintering, 2008)
The alpha-beta phase transformation in Si3N4 was studied for seeded samples using all Y2O3-Al2O3 mixture as a sintering aid. The concentration of beta-seeds varied from 0 to 5 wt.%. The results showed that alpha-beta phase ...
Distribution of stable isotopes in the River Sava in Serbia
(Nukleonika, 2008)
Grab water samples were collected from the research ship ARGUS at four locations in Serbia, Ostruznica (17 rkm), Sabac (103.6 rkm), Sremska Mitrovica (136.4 rkm), and Jamena (195.0 rkm) from the mid-river, and near the ...
Traces of DU in samples of environmental bio-monitors (non-flowering plants, fungi) and soil from target sites of the Western Balkan region
(Journal of Environmental Radioactivity, 2008)
This paper reports results of gamma and alpha spectrometric measurements for mosses, lichens, fungi and soil samples from areas in the Balkans targeted by depleted uranium (DU). Samples were collected in 2002 and 2003 in ...
High-pressure optical studies of Y2O3:Eu3+nanoparticles
(Radiation Effects and Defects in Solids, 2008)
The fluorescence spectra of Y2O3:Eu3+ nanoparticles have been measured under the pressure of up to 78kbar at room temperature. In this pressure range, a red-shift of 0.02(1)nm/kbar-1 is noticed for the 0-2 line (5D07F2 ...
Investigation on bioavailability of some essential and toxic elements in medicinal herbs
(Journal of Natural Medicines, 2008)
Trace and major elements were determined in medicinal herbs (Cynara scolymus, Matricaria chamomilla, Artemisia absinthium L., Achillea millefolium, and Inula britannica) as well as in rhizosphere soil samples. Based on the ...
Electrodeposition of Fe powder from acid electrolytes
(Journal of the Serbian Chemical Society, 2008)
Polarization characteristics of the electrodeposition processes of Fe powders from sulfate and chloride electrolytes and the morphology of the obtained powders were investigated. The morphology depended on the anion presence ...
Assessment of the inhibitory effects of different radiation qualities or chemotherapeutic agents on a human melanoma cell line
(Physica Medica, 2008)
The correlation between time dependent viabilities, after applying two radiation qualities and two alkylating agents on HTB140 melanoma cells, has been studied. Irradiations were performed with gamma-rays and 62 MeV protons, ...
Kinetics of inhibition of peroxidase activity of myeloperoxidase by quercetin
(International Journal of Chemical Kinetics, 2008)
The inhibition of myeloperoxidase (MPO), isolated from human neutrophils, by quercetin was investigated by following peroxidase activity of the enzyme using o-dianisidine as the substrate. The inhibition parameters (IC(50)) ...
Determination of Transient Thermal Interface Resistance Between Two Bonded Metal Bodies using the Laser-Flash Method
(International Journal of Thermophysics, 2008)
The paper presents the data reduction analysis for measurements of the transient thermal interface resistance between two bonded metal bodies using the laser-flash method. By using two different mathematical models, i.e., ...
Radioprotective properties of Gentiana dinarica polyphenols on human lymphocytes in vitro
(Current Science, 2008)
The radioprotective properties of polyphenols from the plant Gentiana dinarica Beck. (family Gentianaceae) were evaluated in cultured human peripheral blood lymphocytes exposed to 2 Gy of gamma radiation in vitro. Major ...
