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

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

Supramolecular polymer based on aminated monosubstituted pillar[5]arene

© 2017, Pleiades Publishing, Ltd. The interaction of nonamethoxypillar[5]arene containing an ester fragment with a series of di- and triamines has yielded novel macrocyclic amide derivatives of pillar[5] arene. The data of NOESY 1 H– 1 H and DOSY NMR spectroscopy, dynamic light scattering, and transmission electron microscopy have revealed that nonamethoxypillar[5]arene containing diethylenediaminoamide moiety can form a network supramolecular polymer with average pores size of 100 nm

Hybrid multicyclophanes based on thiacalix[4]arene and pillar[5]arene: Synthesis and influence on the formation of polyaniline

© 2018 the Partner Organisations. For the first time, fragments of a pillar[5]arene were spatially preorganized with a thiacalix[4]arene core in a single multimacrocyclic structure. It was shown that the synthesized hybrid multicyclophanes bind aniline and do not interact with p-toluenesulfonic acid. Supramolecular assistance of the synthesized multicyclophanes in oxidative polymerization of aniline in aqueous p-toluenesulfonic acid solutions was studied. It was found that the use of the multicyclophane template in the reaction of the oxidative polymerization of aniline led to the formation of emeraldine with a higher molecular weight and a similar conductivity (1-2 mSm cm-1), which formed more stable emeraldine dispersions in acetone in comparison with traditionally obtained polyaniline
