The mechanism of capsaicin-induced apoptosis in colon cancer cells
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 490-493
Both the engagement of the T cell receptor with MHC-Ag complex and a second
costimulatory signal are required for optimal T cell activation. Since T cells
become nonreactive or tolerant without the second signal, blocking the
appropriate costimulatory signal provided by APCs and T cells has been
successful transplantation of allogeneic organs. We investigated the role of
4-1BB, an important costim...

A generalized numerically constructed image system and its use in the calculation of the flow around a ship hull
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 21-24
How to construct an image source system for an arbitrarily shaped body is
considered and its use in calculating the flow around a ship hull is
demonstrated with the example of calculated wave pattern. Only the source
strengths on the free surface, excluding the hull surface sources, play the role
of unknowns by the use of this concept. The full nonlinear free surface boundary
conditions are satisf...

The application of the genetic algorithms in the optimization of transmission systems expansion
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 452-455
This paper is devoted to the electrical network optimization with the help of
genetic algorithms-an optimization method based on the simulation of biological
evolution. This problem is a multi-dimensional nonlinear discrete optimization
problem, which requires the use of heuristic or combinatorial algorithms. The
mathematical model and algorithm of the given problem are developed. The
algorithm of...

Outcomes of overvoltage monitoring and fault location in underground distribution networks
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 447-451
This paper describes an information-measuring system for surge voltages
monitoring and the outcomes of multi-year monitoring in 10 kV underground
distribution networks. The statistical analysis of monitoring outcomes has shown
a low level of the most often overvoltages in networks originating during
restriking earth faults (REFs). For automatic location of REFs, a parametrical
method based on the ...

Coherent production of positronium atom in crystal
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 267-270
The theory of coherent type B positronium atom production by high energy photon
in a real (three dimensional) crystal has been developed. On the basis of the
developed theory the orientation dependence of the positronium atom coherent
type B photoproduction cross-section is studied. It is shown that small change
of the photon energy in the vicinity of coherent peak results in change of
character o...

Dynamic electric strength of liquid perfluorodibutyl ether
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 418-421
An electric strength of perfluorodibutyl ether in small gaps between the
hemispherical electrodes was investigated experimentally under AC voltage of
linearly increasing amplitude. The influence of radius of hemispherical
electrodes, gap lengths and also rate of voltage, increase on probability of
breakdown initiation was investigated experimentally and theoretically. In the
macroscopic stochastic...

Analysis of transient processes in gate control circuits by an operator method
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 355-358
Analysis of gate control circuits by an operator method and description of
external actions by unit step functions in the open switch interval allow to
estimate transient processes in the whole time domain. It is shown, that
transient processes in voltage gate control systems depend on thyristor making
angle.

Thin structures in linear elasticity
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 197-201
This lecture intends to describe the asymptotic behaviour of the displacement in
a linear elastic body containing either a thin non-linear elastic layer or thin
reinforcing fibres, when the thinness of these layer or fibres tends to 0. The
main purpose of this talk is to present the functional analysis which leads to
these asymptotic results in the framework of linear elasticity.

Method of tubes pressing by electrical discharge and its particularities
Proceedings 6th Russian-Korean International Symposium on Science and Technology. KORUS-2002 (Cat. No.02EX565) - - Trang 230-232
In the paper the method of multipulse electrical discharge pressing of heat
exchanger apparatus tubes is considered. The main factor responsible for the
deformation of the tubes is determined. A method for adjusting of deformation is
offered. Technical parameters of apparatus for electrical discharge pressing are
shown.
