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 ...

Fermi-Dirac and Bose-Einstein Functions of Negative Integer Order
(Theoretical and Mathematical Physics, 2009)
We find simple explicit closed-form formulas for the Fermi-Dirac function F(-n)(z) and Bose-Einstein function B(-n)(z) for arbitrary n is an element of N. The obtained formulas involve the higher tangent numbers defined ...
Limit Representations of Riemanns Zeta Function
(American Mathematical Monthly, 2012)
In this article, it is shown that Riemanns zeta function zeta(s) admits two limit representations when R(s) GT 1. Each of these limit representations is deduced by using simple arguments based upon the classical Tannerys ...
Chronic Individual Housing-Induced Stress Decreased Expression of Catecholamine Biosynthetic Enzyme Genes and Proteins in Spleen of Adult Rats
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 ...
Integrated Assessment and Management of Ambient Particulate Matter - International Perspective and Current Research in Serbia
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2012)
Air pollution mitigation is a necessity in Serbia, due to its high levels of criteria pollutants in ambient environment. Successful implementation of mitigation measures requires access to sufficient information from ...
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) ...
Effect of immobilization stress on gene expression of catecholamine biosynthetic enzymes in heart auricles of socially isolated rats
(Brazilian Journal of Medical and Biological Research, 2009)
Chronic stress is associated with the development of cardiovascular diseases. The sympathoneural system plays an important role in the regulation of cardiac function both in health and disease. In the present study, the ...
Synthesis and Structural Characterization of Nano-sized Copper Tungstate Particles
(Acta Chimica Slovenica, 2012)
The nano-sized copper tungstate (CuWO4) was prepared by precipitation method in the presence of non-ionic copolymer surfactant (polyoxyethylene-polyoxypropylene block copolymer) and consequent annealing at low temperature ...
