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 ...
Inapplicability of Small-Polaron Model for the Explanation of Infrared Absorption Spectrum in Acetanilide
(Electromagnetic Biology and Medicine, 2009)
The applicability of small-polaron model for the interpretation of infrared absorption spectrum in acetanilide has been critically reexamined. It is shown that the energy difference between the normal and anomalous peak. ...
Influence of Running Conditions on Resonant Oscillations in Fresh-Air Ventilator Blades Used in Thermal Power Plants
(Thermal Science, 2009)
High-frequency cyclic load of fresh air supply to ventilator blades in thermo energetic facilities can cause the occurrence of fretting in the pressed overlap of ventilator shaft and socket. These loads can be generated ...
Size Distribution of Agglomerates of Milk Powder in Wet Granulation Process in a Vibro-Fluidized Bed
(Brazilian Journal of Chemical Engineering, 2009)
Results of experiments on the influence of technological parameters (intensity of vibration, granulation of the liquid feed, temperature of fluidization agent) on the change of size distribution, as well as mass mean ...
First results studying the transmutation of (129)I, (237)Np, (238)Pu, and (239)Pu in the irradiation of an extended (nat)U/Pb-assembly with 2.52 GeV deuterons
(Journal of Radioanalytical and Nuclear Chemistry, 2009)
An extended U/Pb-assembly was irradiated with an extracted beam of 2.52 GeV deuterons from the Nuclotron accelerator of the Laboratory of High Energies within the JINR in Dubna, Russia. The lay-out of this experiment and ...

Ferromagnetic behaviour of the Zn-Mn-O system
(Journal of the Serbian Chemical Society, 2009)
Polycrystalline Zn-Mn-O samples with nominal manganese concentrations x = 0.0 1, 0.04 and 0.10 were synthesized by a solid state reaction route using (ZnC(2)O(4 center dot)2H(2)O)(1-x) and (MnC(2)O(4)-2H(2)O)(x). Thermal ...
The non-isothermal thermogravimetric tests of animal bones combustion. Part. I. Kinetic analysis
(Thermochimica Acta, 2009)
The non-isothermal combustion of animal bones was investigated by simultaneous thermogravimetric and differential thermal analysis (TG-DTA), in the temperature range Delta T = 20-650 degrees C. The full kinetic triplet (A, ...
Antioxidant enzymes and lipid peroxidation in endometrium of patients with polyps, myoma, hyperplasia and adenocarcinoma
(Reproductive Biology and Endocrinology, 2009)
Background: Oxidative stress and impaired antioxidant system have been proposed as a potential factors involved in the pathophysiology of diverse disease states, including carcinogenesis. In this study, we explored the ...
Physical and chemical characterization of the particulate matter suspended in aerosols from the urban area of Belgrade
(Journal of the Serbian Chemical Society, 2009)
Within this study, attempts were made to characterize the coarse and fine particulate aerosol fractions in urban area of Belgrade and define the inorganic chemical composition of the aerosol fractions. For this purpose, ...
