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 ...
Complete relaxation map of polypropylene: radiation-induced modification as dielectric probe
(Polymer Bulletin, 2012)
The molecular relaxation behaviour of isotactic polypropylene (iPP) exposed to gamma radiation in air to various absorbed doses (up to 700 kGy) has been investigated by dielectric loss (tan delta) analysis; the polar (mainly ...
Cs-137 and K-40 in some traditional herbal teas collected in the mountain regions of Serbia
(Isotopes in Environmental and Health Studies, 2014)
Herbal teas are an important part of traditional medicine in Serbia. The objective of the present study was to determine the activity concentrations of K-40 and Cs-137 in herbal tea, using the gamma spectroscopy method. ...
Radioactivity Measurements in Soils Surrounding Four Coal-Fired Power Plants in Serbia By Gamma-Ray Spectrometry and Estimated Dose
(Nuclear technology and radiation protection, 2014)
The study of spatial distribution of activity concentration of U-238, Ra-226, (210)pb, Th-232, K-40 and Cs-237 radionuclides in the surface soil samples (n = 42) collected in the vicinity of four coal-fired power plants ...
Glycidyl methacrylate macroporous copolymer grafted with diethylene triamine as sorbent for Reactive Black 5
(Hemijska industrija, 2014)
In this paper, macroporous glycidyl methacrylate and ethylene glycol dimethacrylate copolymer functionalized with diethylene triamine (PGME-deta), was evaluated as Reactive Black 5 (RB5) sorbent. Batch RB5 removal from ...
Photocatalytic Performance of Carbon Monolith/TiO2 Composite
(Advances in Materials Science and Engineering, 2015)
The new and simple approach for deposition of catalytically active TiO2 coating on carbon monolith (CM) carrier was presented. CM photocatalysts were impregnated with TiO2 using titanium solution and thermal treatment, and ...
Effects of Levothyroxine Replacement Therapy on Parameters of Metabolic Syndrome and Atherosclerosis in Hypothyroid Patients: A Prospective Pilot Study
(International Journal of Endocrinology, 2015)
The aim of this study was to investigate the effect of levothyroxine (LT4) replacement therapy during three months on some parameters of metabolic syndrome and atherosclerosis in patients with increased thyroid-stimulating ...
Hypermethylation of p15 Gene in Diffuse - Large B-Cell Lymphoma: Association with Less Aggressiveness of the Disease
(Clinical and Translational Science / CTS, 2014)
In this study, methylation-specific polymerase chain reaction was used to investigate the potential prognostic significance of the methylation status of p15, p16, MGMT, and DAPK genes in 51 specimens of diffuse large B-cell ...
