Temporal variations of the radioactivity in the near ground layer of air
(Radiochimica Acta, 1996)
The concentration of radionuclides in the layer of air above the ground continuously varies due to entry and exit of radionuclides both from the earth and atmosphere and decay processes. We have tried to establish the ...
Some observations on mechanical activation of the CeO2-ZrO2-SiO2 system
(Journal of Alloys and Compounds, 1999)
Mechanical activation of CeO2-ZrO2-SiO2 mixtures was performed in a high energetic vibratory mill with WC lining and grinding media. It was shown that in air atmosphere the reduction of Ce4+ into Ce3+ took place at 1400 ...
Effect of wave damping on the nonlinear saturation of stimulated Raman scattering in a finite homogeneous plasma
(Physica Scripta, 1996)
A question of stationarity of a nonlinear saturated regime of stimulated Raman backscattering in a finite homogeneous plasma is considered. Slowly varying envelope equations with the damping and the nonlinear frequency ...
Thermal diffusivity of the candidate standard reference material cordierite
(High Temperatures: High Pressures, 1999)
The results of an international programme carried out to qualify transfer or reference standards for thermal transport properties, thermal conductivity and thermal diffusivity, in the range between 1 W m(-1) K-1 and 5 W ...
The relation between the scaling of Husimi functions and the linear phase insensitive amplification of the corresponding quantum states and its implications
(Journal of Physics. A: Mathematical and General, 1996)
Using the description of the linear phase insensitive amplification of a quantum state available in the literature we prove that to every state rho(t), produced from the initial state rho(0) by such amplification, there ...
Ordinary waves in relativistic plasmas
(Plasma Physics and Controlled Fusion, 1998)
The propagation and absorption of ordinary waves in fully relativistic plasma are investigated. Several interesting effects introduced by the relativistic mass increase associated with an increase in the electron temperature ...
Spectral and electrical characteristics of a stabilized DC arc seeded with potassium
(Contributions to Plasma Physics, 1997)
A systematic investigation of spectral and voltage-current (U-I) characteristics of a DC are plasma was performed. The vertical, argon and wall stabilized DC are plasma was seeded by an easily ionizable element (EIE), ...
Dielectric properties of metal salts of heteropolyacid hydrates
(Solid State Phenomena, 1998)
Heteropolyacids hydrates as superionic conductors have been intensely investigated during the last fifteen years. By using various experimental techniques such as IR and Raman spectroscopy, neutron scattering, impedance ...
Phase composition and fracture toughness of Si3N4-ZrO2 with CeO2 additions
(Ceramics International, 1999)
Zirconia toughened Si3N4 was prepared with addition of CeO2 by applying hot pressing technique. Phase composition, densification, fracture toughness and hardness were investigated as a function of hot pressing temperature ...
Minimal residual, disease in CML patients submitted to stem cell transplantation
(Bone Marrow Transplantation, 1999)
