Structure and Magnetic Investigations of Ca1+xYxMnO3 (x=0, 0.1, 0.2, 0.3) and Mn4+/Mn3+ Relation Aanalysis
(Science of Sintering, 2010)
Structure and magnetic features of nanostructured materials with general formula Ca1-xYxMnO3 (x = 0; 0.1; 0.2; 0.3) were investigated. Goldschmidt tolerance factor, G, and global instability index, GII were calculated for ...
Properties of Isotactic Polypropylene Irradiated in Various Atmospheres
(Hemijska industrija, 2010)
In this paper, changes in structure and physical properties of stabilized isotactic polypropylene (iPP) were created by gamma irradiation, up to a dose of 700 kGy, in different media: air, deionized distilled (DD) water ...
Application of the Laser Pulse Method of Measuring Thermal Diffusivity to Thin Alumina and Silicon Samples in a Wide Temperature Range
(Thermal Science, 2010)
Paper presents results of measuring thermal diffusivity of translucent or partially transparent thin discs of non-metals such as alumina and silicon using most widely spread experimental technique, the standard laser pulse ...
Chronic Individual Housing-Induced Stress Decreased Expression of Catecholamine Biosynthetic Enzyme Genes and Proteins in Spleen of Adult Rats
(Neuroimmunomodulation, 2010)
Objective: Social isolation is regarded as one of the most relevant causes of diseases in mammalian species. The activation of the sympathoneural system represents one of the key components of the stress response. The ...
Changes of Structural and Hydrogen Desorption Properties of Mgh2 Induced By Ion Irradiation
(Hemijska industrija, 2010)
Changes in structural and hydrogen desorption properties of MgH2 induced by ion irradiation have been investigated. Powder samples of MgH2 have been irradiated with 45 keV B3+ and 120 keV Ar8+, with ion fluence of 10(15) ...
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 ...
Spin Glass Dynamics of Nanoparticle La0 7Ca0 3Mn0 7Fe0 3O3 Obtained by a Mechanochemical Milling
(Acta Physica Polonica. Series A: General Physics, Physics of Condensed Matter, Optics and Quantum Electronics, Atomic and Molecular Physics, Applied Physics, 2010)
Spin dynamics of nanoparticle La0 7Ca0 3Mn0 7Fe0 3O3 system was studied through the set of diverse magnetic measurements Analysis of the data obtained from magnetic relaxation measurements, memory effect and AC susceptibility ...
Correlation of Structural and Optical Properties of Sputtered FeSi2 Thin Films
(Japanese Journal of Applied Physics, 2010)
Iron-disilicide films were sputter deposited on Si(100) wafers to 300-400 nm, at substrate temperatures ranging from room temperature to 700 degrees C As-deposited films were amorphous at deposition temperatures up to 200 ...
Subsequent stress increases gene expression of catecholamine synthetic enzymes in cardiac ventricles of chronic-stressed rats
(Endocrine, 2010)
Since previous experience of stressful situation profoundly affects response to a subsequent novel stressor, we examined changes in gene expression and protein levels of catecholamine biosynthetic enzymes in cardiac ...
Chronic Social Isolation Compromises the Activity of Both Glutathione Peroxidase and Catalase in Hippocampus of Male Wistar Rats
(Cellular and Molecular Neurobiology, 2010)
Chronic neuroendocrine stress usually leads to the elevation of the stress hormones and increased metabolic rate, which is frequently accompanied by oxidative damage to the CNS. In the present study we hypothesized that ...
