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 ...
ATP and ADP hydrolysis in cell membranes from rat myometrium
(Molecular and Cellular Biochemistry, 2012)
Extracellular nucleotides affect female reproductive functions, fertilization, and pregnancy. The aim of this study was to investigate biochemical characteristics of ATP and ADP hydrolysis and identify E-NTPDases in ...
Kinetic and thermodynamic analysis of Creosote degradation process under isothermal experimental conditions
(Journal of Environmental Science and Health. Part A: Toxic Hazardous Substances and Environmental Engineering, 2013)
Isothermal degradation process of commercial Creosote was analyzed by the thermogravimetric (TG) technique in a nitrogen atmosphere, at four different operating temperatures (230, 250, 270 and 290 degrees C). The kinetic ...
Effects of altered hepatic lipid metabolism on regulation of hepatic iNOS
(Clinical Lipidology, 2015)
An altered hepatic lipid metabolism involves multifactorial pathologies such as hepatic inflammation, insulin resistance and oxidative stress. Immunity has an essential role in the regulation of glucose and lipid metabolism ...
The Impact of Radiation on Semiconducting Characteristics of Monocrystalline Silicon and Germanium
(Nuclear technology and radiation protection, 2016)
The paper examines the effects of radiation on the electrical characteristics of monocrystalline silicon and germanium. Samples of monocrystalline silicon and germanium are irradiated under controlled laboratory conditions ...
Advances in the science of light
(Optical and Quantum Electronics, 2016)
Transition metal complexes with thiosemicarbazide-based ligands. LIII. [4-(2-diphenylphosphino-alpha-ethoxybenzyl-kappa P)-S-methyl-1-(4-oxidopent-3-en-4-ylidene-kappa O)-thiosemicarbazido-kappa(2) N-1, N-4]nickel (II)
(Acta Crystallographica. Section C: Crystal Structure Communications, 2006)
The title compound, [Ni(C28H30N3O2PS)], crystallizes with two independent molecules in the asymmetric unit. The Ni-II atoms are in significantly deformed square-planar environments formed by an ONNP donor set from a ...
Influence of Organic Cations Sorption on the Point of Zero Charge of Natural Zeolite
(Hemijska industrija, 2009)
In this paper, the results of the surface modification of natural zeolite with different amounts (2, 5 and 10 mmol M(+)/100 g) of octadecyldimethylbenzyl ammonium ions (ODMBA) are presented. The obtained organozeohtes were ...
Prevention and recovery of CuSO4-induced inhibition of Na+/K+-ATPase and Mg2+-ATPase in rat brain synaptosomes by EDTA
(Toxicology Letters, 1999)
Enzymatic activities of Na+/K+-ATPase and Mg2+-ATPase from rat brain synaptic plasma membrane were studied in the absence and presence of EDTA. The aim of the study was to examine the ability of this strong chelator to ...
Nondestructive Testing of Thermal Shock Resistance of Cordierite/Silicon Carbide Composite Materials After Cyclic Thermal Shock
(Research in Nondestructive Evaluation, 2010)
Two different types cordierite/silicon carbide composite ceramic materials (KS 50 and KZ 50) were used for this investigation. Both materials were exposed to the water quench test from 950 degrees C, applying various numbers ...
