Radiochemical studies of the sorption behavior of strontium and barium
(Kluwer Academic Publishers, 1995)
The sorption behavior of strontium and barium on kaolinite, bentonite and chlorite-illite mixed clay was studied by radioanalytical techniques using the batch method.90Sr (29.1 y) and133Ba (10.5 y) were used as radiotracers. ...
Screening effects on the confined and interface polarons in cylindrical quantum wires
We study the contribution of confined and interface phonons to the polaron energy in quantum-well wires. We use a dispersionless, macroscopic continuum model to describe the phonon confinement in quantum wires of circular ...
TELPACK: An Advanced teletraffic analysis package
Performance evaluation of computer and communication networks gives rise to teletraffic problems of potentially large dimensionality. We briefly summarize a unifying system theoretic approach to efficient solution of a ...
Genetic aspects of hepatocellular carcinogenesis
Hepatocellular carcinoma (HCC) is linked etiologically to viruses (hepatitis B virus [HBV] and hepatitis C virus [HCV]), chemical carcinogens (i.e., aflatoxins), and other environmental and host factors causing chronic ...
Raman studies of doped polycrystalline silicon from laser-annealed, doped a-Si:H
We have used Raman scattering to follow the progress of multiple-pulse (sub-melt-threshold) laser annealing in doped hydrogenated amorphous silicon films (a-Si:H) on glass. In phosphorous-doped a-Si:H the Raman signal shows ...
Multi-Hamiltonian structure of equations of hydrodynamic type
We complete the discussion of the Hamiltonian structure of 2-component equations of hydrodynamic type by presenting the Hamiltonian operators for Euler's equation governing the motion of plane sound waves of nite ...
Discrete fractional Fourier transform
(IEEE, Piscataway, NJ, United States, 1999)
We propose and consolidate a definition of the discrete fractional Fourier transform which generalizes the discrete Fourier transform (DFT) in the same sense that the continuous fractional Fourier transform (FRT) generalizes ...
Pole assignment problem: A structural investigation
Based on the structure of a closed-loop system under a specified feedback pattern, a qualitative analysis of the problem of pole assignability is considered. The problem is first formulated algebraically, in terms of the ...
Low-temperature photoluminescence spectra of layered semiconductor TlGaS2
Photoluminescence (PL) spectra of TlGaS2 layered single crystals were studied in the wavelength region 500-860 nm and in the temperature range 9.5-293 K. We observed a total of three PL bands centered at 568 nm (2.183 eV, ...
Defects of Irreducible Characters of p-Soluble Groups
We prove a refinement of thep-soluble case of Robinson's conjectural local characterization of the defect of an irreducible character. © 1998 Academic Press.
