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 ...
Kinetic properties of multiquanta Davydov-like solitons in molecular chains
(Physical Review E, 1999)
The Fokker-Planck equation for multivibron solitons interacting with lattice vibrations in a molecular chain has been derived by means of the nonequilibrium statistical operator method. It was shown that a soliton undergoes ...
Catalytic preparation and characterization of C60Br24
(Fullerene Science and Technology, 1998)
In this paper the procedure for catalytical bromination of C60 with elementary bromine with FeBr3 as a catalyst is described In this procedures only one reaction product - C60 Br24 is obtained. The twenty four bromine atoms ...
Calculational and experimental investigations of void effect. A new model for leakage treatment of heterogeneous assemblies
(International conference on mathematical methods and supercomputing in nuclear applications; Karlsruhe (Germany); 19-23 Apr 1993., 1993)
The growing interest in safety problems had led physicists to try to increase their knowledge of the neutron leakage phenomenon, both by calculation and by experiment The flux calculation in a heterogeneous assembly is ...
Thermochemical behavior of C60. Kinetics of decomposition in different atmospheres / Термохемијско понашање угљеника C60. Кинетика разлагања у различитим атмосферама
(Journal of the Serbian Chemical Society, 1997)
The processes of decomposition of C60 in different atmospheres were investigated by TG and DTG methods. It was observed that the temperature maxima on the DTG curves are shifted towards higher temperatures by about 200 K ...
Učestalost aktivacije RAS onkogena u planocelularnih karcinoma donje usne / Activation of frequency of RAS oncogenes in planocellular carcinoma of the lower lip
(Stomatološki glasnik Srbije, 1993)
Tačkaste mutacije RAS protoonkogena dovode do njihove aktivacije čime ovi geni stiču sposobnost indukovanja maligne transformacije. Učestalost mutiranih RAS gena veoma varira od jednog tipa do drugog, a podatak o učestalosti ...
BN theory: Advances and new models for neutron leakage calculation
(Advances in Nuclear Science and Technology, 1997)
Nuclear reactor physics design and analysis requires broad knowledge of parameters affecting reactor operation Power distributions, control rod worth, shut down margins, isotopic depletion rates, etc, have to be determined ...
SRNA: a Monte Carlo code for proton transport simulation
(6. Workshop on heavy-charged particles in biology and medicine; Baveno (Italy), 1997)
Tibere and Tibere-2: new consistent models for calculation of space-dependent directional leakage coefficients for a heterogenous assembly
(Institute of Nuclear Sciences VINCA, 1997)
The influence of nuclear reactor core lattice heterogeneity on neutron leakage has been taken into account by two leakage models named TIBERE and TIBERE-2 These models are founded on the heterogenous Bn theory, that the ...
