Development of solidification techniques for radioactive sludge produced by a research reactor
(Progress in Nuclear Energy, 2004)
In the last forty years in the Vinca Institute, as a result of the operation of two research reactors, named RA and RB, and as a result of the application of radionuclides in medicine, industry and agriculture, radioactive ...
Modeling of 3-D non-gray gases radiation by coupling the finite volume method with weighted sum of gray gases model
(International Journal of Heat and Mass Transfer, 2004)
A new model and code for radiative heat transfer based on the numerical solution of the radiative transfer equation by finite volume method in 3-D Cartesian coordinates coupled with weighted sum of gray gases model (WSGGM) ...
Synthesis of in situ reinforced silicon nitride composites
(Journal of the Serbian Chemical Society, 2004)
The objective of this work was to investigate the effect of two different sintering additives (CeO2 and Y2O3 + Al2O3), sintering time and amount of beta-Si3N4 seeds on the densification. mechanical properties and microstructure ...
The determination of the thermal neutron flux density by the measurement of the activities ratio Au-199/Au-198
(Radiation Measurements, 2004)
Thermal neutrons produce isotopes of Au-198 and Au-199 in the two successive (n,y) reactions in irradiated gold. The ratio of their activities is proportional to the flux of the thermal neutrons, which was used for ...
Antibodies reactive with C-terminus of the second conserved region of HIV-1gp120 as possible prognostic marker and therapeutic agent for HIV disease
(Journal of Clinical Virology, 2004)
It has been reported that antibodies reactive with peptide RSANFTDNAKTIIVQLNQSVEIN (peptide NTM) derived from the C-terminus of the second conserved domain of HIV-1 envelope glycoprotein gp120 could represent an important ...
Influence of anisotropy of Compton scattering on low energy x-ray reflection
(Journal of Physics. D: Applied Physics, 2004)
The reflection of x-rays from a semi-infinite water target, for energies ranging from 10 to 60 keV, often used in x-ray diagnostics, is investigated by Monte Carlo simulation. The same process was also treated analytically ...
Characterization of dispersion strengthened copper with 3wt%Al2O3 by mechanical alloying
(Science of Sintering, 2004)
The copper matrix has been dispersion strengthened with 3wt. %Al2O3 by mechanical alloying. Commercial alumina powder with an average particle size of 0.751 mum was used for alloying. The mechanical alloying process was ...
Cobalt(II) chloride complex formation in acetamide-calcium nitrate tetrahydrate melts
(Journal of Solution Chemistry, 2004)
The absorption spectra of Co(II) chloride complexes, containing variable concentrations of chloride ligand, in a molten mixture of 80 mol% acetamide-20 mol% calcium nitrate tetrahydrate, were studied at 313, 333, 353, and ...
Thermal diffusivity measurements of thermographite
(International Journal of Thermophysics, 2004)
This paper presents results of measurements of a graphite proposed to serve as a thermophysical property reference or standard reference material. The reported measurements contribute to a program launched in 1999 by Anter ...
