Structural modifications of Cu(II) 12-tungstophosphoric acid salit studied by IR and Raman spectroscopy
(Journal of the Serbian Chemical Society, 2000)
In this paper local processes and structural phase transformations of the copper salt of 12-tungstophosphoric acid are investigated. The structural phase transformations were followed through bands, characteristic for the ...
An attemp to use a pulsed CO2 laser for decontamination of radioactive metal surfaces
(Journal of the Serbian Chemical Society, 2000)
There is a growing interest in laser radioactive decontamination of metal surfaces. It offers advantages over conventional methods: improved safety, reduction of secondary waste, reduced waste volume, acceptable cost. The ...
Modification of the aluminum for making offset printing plates
(Journal of the Serbian Chemical Society, 2000)
Aluminum as the base of offset printing plates should make good contact with wetting agents and the light sensitive layer and should be resistant to wear and cracking. In order to achieve this, the aluminum is roughened ...
A simplified approach to the vibrational self-relaxation of simple molecules through convolution of their velocities
(Journal of the Serbian Chemical Society, 2000)
A theoretical approach has been developed for computing collisional self-relaxation probabilities of the first excited level in the lowest vibrational mode of simple molecules. The bending (nu(2)) vibration in triatomic ...
A frequency stabilized waveguide CO2-laser for photoacoustic spectroscopy of gases
(Journal of the Serbian Chemical Society, 2000)
A theoretical model of a waveguide CO2-laser was made to optimize the dimensions of the waveguide tube and resonator, i.e., to obtain the best mode structure while maximizing the output power. The results were used to ...
Effect of steroid hormone deprivation on the expression of ecto-ATPase in distinct brain regions of female rats
(Physiological Research, 2000)
Abundant evidence indicates that ATP and adenosine act as neurotransmitters or co-transmitters, influencing nerve cell physiology in various ways. Therefore, regulation of ATP-metabolizing enzymes is essential for the ...
Estradiol affect Na-dependent Ca2+ efflux from synaptosomal mitochondria
(General Physiology and Biophysics, 2000)
The effects of gonadal steroid hormone, 17 beta-estradiol (E-2), in vitro on rat brain mitochondria Ca2+ movement were investigated. Intrasynaptosomal mitochondria Ca2+ uptake via an energy-driven Ca2+ uniporter have K-m ...
Determination of the critical molar mass of ovalbumin oligomers degraded by ultrasound
(Journal of the Serbian Chemical Society, 2000)
An experimental method has been developed which enables the determination of the critical molar mass (Mmc) of ovalbumin oligomers degraded by ultrasound of known frequency. To test the validity of the Mmc postulate, a ...
Inter-protein bonding and other molecular interactions in hen egg white
(Journal of the Serbian Chemical Society, 2000)
The analysis of the SDS-polyacrylamide gel electrophoresis (SDS-PAGE) data, combined with the comparison of viscosity data corresponding to the, thin fraction of hell egg white and 2 mM purefied ovalbumin solution, showed ...
Distribution of HCV genotypes among risk groups in Serbia
(European Journal of Epidemiology, 2000)
Blood samples from 190 patients that were anti-hepatitis C virus (HCV) positive were genotyped and 165 were found to contain HCV-RNA. Genotyping was performed by PCR based on type-specific primers (117 isolates) and LiPA ...
