Investigation of cosmic ray propagation in interplanetary space

It was established experimentally that propagation of solar cosmic rays (scr) in interplanetary space up to 1 AU in most cases was of diffusion character

Characteristic of the snow cover for the Western Siberia territory

The warming for the Siberian territory has more rapid growth, than for Northern Hemisphere, in general. The purpose of the work is the description of characteristics of a snow cover for the south-east territory of the Western Siberia, which is great importance for many branches of the economy of Siberia. Date of appearance of snow cover, duration of a steady snow cover, thickness were analyzed in present research. The presented results are: the increase in duration of the presence the snow cover is revealed. The reason is the increase in amount of precipitation during the winter period

Effect of long-term operation on energy band bending at the SnO2 microcrystals interfaces in thin tin dioxide films with various catalysts

This work presents the results of investigation of stability of energy band bending at the SnO2 microcrystals interfaces in thin films of tin dioxide with deposited Pt and Pd dispersed layers (Pt/Pd/SnO2:Sb) and with the additions of gold in the bulk and on the surface (Au/SnO2:Sb, Au) in long - term operation. Measurements of energy band bending were showed that the significantly variation of this value is observed in first month of the sensor using. Perhaps this phenomenon is caused by the surface reconstruction during operation of sensors and consequently by the increase of density of oxygen ions chemisorbed on the surface of tin dioxide

Operator Approach to the Master Equation for the One-Step Process

Presentation of the probability as an intrinsic property of the nature leads researchers to switch from deterministic to stochastic description of the phenomena. The procedure of stochastization of one-step process was formulated. It allows to write down the master equation based on the type of of the kinetic equations and assumptions about the nature of the process. The kinetics of the interaction has recently attracted attention because it often occurs in the physical, chemical, technical, biological, environmental, economic, and sociological systems. However, there are no general methods for the direct study of this equation. Leaving in the expansion terms up to the second order we can get the Fokker-Planck equation, and thus the Langevin equation. It should be clearly understood that these equations are approximate recording of the master equation. However, this does not eliminate the need for the study of the master equation. Moreover, the power series produced during the master equation decomposition may be divergent (for example, in spatial models). This makes it impossible to apply the classical perturbation theory. It is proposed to use quantum field perturbation theory for the statistical systems (the so-called Doi method). This work is a methodological material that describes the principles of master equation solution based on quantum field perturbation theory methods. The characteristic property of the work is that it is intelligible for non-specialists in quantum field theory. As an example the Verhulst model is used because of its simplicity and clarity (the first order equation is independent of the spatial variables, however, contains non-linearity). We show the full equivalence of the operator and combinatorial methods of obtaining and study of the one-step process master equation.Comment: in Russian; in Englis

Дослідження складу і властивостей виділеного з хрону препарату пероксидази

Using the precipitation of proteins by zinc and ammonium sulfates, then by polymer and subsequent dialysis,the peroxidase preparation from horseradish roots was isolated (RZ=0.7), with yield by protein 1.7 % and specificperoxidative activity 7.6 U. By SDS -electrophoresis method it was verified the obtaining of partially purified peroxidasepreparation with molecular mass (43±0.5) kDa. By the native electrophoresis method it was determined, that 80.8 %of the total preparation protein possesses expressed peroxidase activity.Из корней хрена способом осаждения белков сульфатами цинка и аммония, путем использования полимера и диализа выделен препарат пероксидазы (RZ 0,70) с выходом белка 1,7 %, удельной окислительновосстановительной активностью 7,6 Е д.
