A simplified heterogeneous B1 model with isotropically-reflected neutrons on assembly boundary
(Proceedings of the 1994 nuclear simulation symposium, 1994)
This model is based on the heterogeneous B1 theory and accounts for heterogeneous effects on the neutron streaming At the price of some approximations, it yields an iterative scheme to simultaneously compute the multigroup ...
Calculational and experimental investigations of void effect - A simple theoretical model for space-dependent leakage treatment of heterogeneous assemblies
(Nuclear Science and Engineering, 1994)
This method, which takes into account the influence of assembly heterogeneity on neutron leakage, is based on the heterogeneous B1 formalism, which assumes the existence of a fundamental mode in an infinite and regular ...
Nickel film orientation change by nitrogen ion bombardment during deposition
(Vacuum, 1997)
The influence of nitrogen ion bombardment during e-beam triode ion plating of nickel on the microstructure and film orientation has been investigated. The deposition variables explored were the ion current density and ...
Measurement of thermal diffusivity of thin films by the AC calorimetric method
(High Temperatures: High Pressures, 1998)
Materials in the form of thin films are increasingly used in electronics and industry. In order to gain full control over fabricated thin-film ultimate properties, methods for their thermal characterisation are necessary. ...
Simulations of anomalous stimulated Raman backscattering in a bounded plasma
(Journal of the Physical Society of Japan, 1998)
Temporal pulsations, bursting and incoherence of stimulated Raman backscatter in a bounded, underdense plasma were observed in relativistic particle-in-cell simulations. We show that backscatter complexities, modulated and ...
The role of solitons in charge and energy transfer in 1D molecular chains
(Physica. D: Nonlinear Phenomena, 1998)
The idea that polarons and solitons could play the crucial role in the transport processes in biological structures, has been critically reexamined on the basis of the general theory of self-trapping phenomena. The criteria ...
Human extracellular proteins display a different pattern of local sequence similarity with the four classes of human T-cell receptor V regions than foreign proteins and human intracellular proteins: a preliminary report
(Immunology Letters, 1998)
A pool of 110 randomly selected/generated amino acids sequences was used to perform specific local sequence similarity alignment analysis with the pool of 279 reported sequences of human T-cell receptor (TCR) V-regions. ...
Study of apoB gene signal peptide insertion/deletion polymorphism in a healthy Serbian population: no association with serum lipid levels
(Clinica Chimica Acta, 1997)
The apolipoprotein B (apoB) signal peptide polymorphism was studied in unrelated healthy individuals. A total of 232 women and 222 men were analyzed separately. The relative frequencies of Del allele in women and men were ...
Vibrational structure of the B-X system of isotopic AgO molecules
(Spectroscopy Letters, 1999)
Spectra of (AgO)-Ag-107-O-18 and (AgO)-Ag-107-O-16 molecules have been obtained in a low-pressure are in oxygen atmosphere, and recorded with medium dispersion. Vibrational assignments for the bands of B(2)Pi-X(2)Pi system ...
Precipitation of radiation belt electrons by magnetospherically reflected whistlers
(Journal of Geophysical Research - Space Physics, 1998)
We use a test particle simulation model based on gyro-averaged equations of motion to study the influence of oblique magnetospherically reflected (MR) whistlers on the near-loss-cone distribution function of radiation belt ...
