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 ...
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 ...
A quasi-isotropic reflecting boundary condition for the TIBERE heterogeneous leakage model
(Nuclear Science and Engineering, 1996)
The influence of assembly or cell heterogeneity on neutron leakage has been consistently taken into account in the TIBERE simplified heterogeneous B1 model The assumption adopted within the TIBERE model that neutrons are ...
The tight-binding model corresponding to the quantum kicked rotor for a spin-12 particle in the magnetic field
(Physics Letters A, 1994)
The quantum kicked rotor model with a spin degree of freedom coupled to a magnetic field is proposed. The model is mapped into the system of the tight-binding equations and then the localization problem is considered.
The chemical pseudopotential of the spin-orbit interaction
(Physica B: Condensed Matter, 1990)
In this paper the general formula for the spin-orbit chemical pseudopotential is derived which can be applied to the energy band structure calculation at an arbitrary k point in the Brillouin zone. The formula was tested ...
Effects of quantum lattice fluctuations on vibron pairing in two-site systems
(Physical Review B: Condensed Matter and Materials Physics, 1996)
The existence of a two-vibron (amide-I quanta) bound state has been examined within the framework of a two-site realization of the Davydov model. The parameter space of the system is divided into two regions where the ...
