In this paper effect of resistive switch for polymer materials was observed in polystyrene containing metal micro particles Al, Zn with metal concentration close to the percolation threshold. Stable – up to 106 and fast – less than 10 ns switches were obtained. Critical voltages for switching from non-conducting to conducting state for devices with contact distances less than 1 mm did not exceed 10 V. This phenomenon makes it possible to produce memory devices with assumable future down-scaling.

The quality factor of mixed radiation induced by bremsstrahlung
Belousov Alexandr V. Osipov Alexey S. Chernyaev Alexandr P.
In work the contribution of the heavy charged particles, formed as a result of photonuclear reactions, to the absorbed and equivalent dose created by bremsstrahlung in biological matter is investigated. The technique of an estimation of average qiality factor (QF) photoprotons is developed. The mathematical model is developed, allowing to estimate in terms of quality factor, biological action of the mixed radiation induced by bremsstrahlung. The developed model can be easily extended to other types of primary radiation.

Was experimentally investigation spatial dynamics of fibrin clot lysis in vitro. The effect of plasminogen activators (streptokinase and urokinase) on growth and lysis of fibrin clot in a reaction-diffusive system. Discovered the phenomena that the addition of plasminogen activators in therapeutic concentrations in addition fibrinolysis system actuates coagulation system, and wave of fibrinolysis starts from place of coagulation activation.

Drift of the internal transition layer is investigated for the pseudo-parabolic thira order equation in the heterogeneous medium in case of the contrast structure like solution. Method of the singular expansion of the decision into the series by powers of the small parameter is used. Seversl basic terms of the series for the velocity of the internal

Self-energy of a scalar charge
Grats Yu.V.
The problem of self-energy of a classical charged particle in a curved static space-time is considered. The expression for the regularized self-energy of a scalar charge in a~$(n+1)$~-- dimensional space-time is obtained with the use of the dimensional regularization method. The particular case of two spatial dimensions is considered. It is shown that dimensional regularization leads to the results which are in agreement with the results obtained with the use of other methods of regularization.
