ANALYSIS OF THE PROCESSES CAUSED THE MAGNETIC FIELD INFLUENCE ON A STRUCTURE AND PROPERTIES OF WATER
01.00.00 Physical-mathematical sciences
Description
The scientific publications review about a magnetic field influence on cluster sizes and their concentration was carried out. These structural changes are attended by the water system physicochemical properties changes. For example, the surface tension coefficient changes. It is shown, that the conductivity and the dielectric constant of water change in a weak magnetic field. It is provided, that characteristics of water activated by a magnetic field can save in a significant time

WATER STRUCTURE AND DILUTE WATER SYSTEM PROPERTIES ANALYSIS
01.00.00 Physical-mathematical sciences
Description
The cluster structure in pure water (distilled) and water salt solution was considered. The experimental methods of the structural units’ registration in water were analyzed. It is shown that the clusters influence on water properties is insignificant by salt concentration more than 10-5 mole

Description
Specially formed mixtures of isotopes of chemical elements have better consumer properties than their natural counterparts. Therefore, the development of methods for increasing the efficiency of the known methods for producing of isotope materials is relevant. It is known that the chemical bond is formed only in the singlet state of the spins of valence electrons of the reagents. On the basis of the known representations about dispersion of spin projections on the coordinate axes and the molecular-kinetic theory of gases was obtained an expression for the constant of the chemical reaction between the radicals occurring in the magnetic field. This expression allows calculating the reactivity of the isotopic modifications of radicals. Plasma allows to transfer many of the compounds in the gas phase. It is known that a significant part of particles in low temperature plasma is in a radical form. The equations of chemical kinetics for describing the process of oxidation of the carbon isotopes in argon-oxygen plasma occurring in an external permanent magnetic field were written in the work. It was shown that the efficiency of plasma process of isotopes separation can be increased only under insufficient oxygen relative to the stoichiometric value. These equations of chemical kinetics of processes occurring in the plasma process of incomplete oxidation of carbon isotopes needed to find experimental conditions that provide the maximum isotope effect in a magnetic field

ISOTOPIC REDISTRIBUTION IN PRODUCTS OF PLASMA PROCESSES FOR HIGH FREQUENCY DISCHARGES
01.00.00 Physical-mathematical sciences
Description
Researches in plasma methods for isotopes separation and analyze of the results were done. Results show high values of separation coefficient for intermediate products during the last years. It is shown by us, that these factors will be considerably reduced in the subsequent plasma processes and a way of freezing of high value of factor of division of isotopes

INTERFEROMETRIC METHOD OF LASER RADIATION TRANSMISSION USING FREE SPACE OPTICS
01.00.00 Physical-mathematical sciences
Description
The analysis of the various conditions of the two (four) laser radiation streams coherent addition was realized. It is shown that it is possible to create devices providing continuous subtraction of waves. In such radiation stream a continuous subtraction on the line can be replaced by the continuous addition on the photomultiplier by using a dispersive delay line. The research results can be used for creation of modern open atmospheric connection lines

Description
The article is devoted to the study of factors of adaptation of Chinese students to educational environment of TPU. The goal of this work is to identify influence of different factors on adaptation of foreign students studying in Tomsk Polytechnic University. Various methods of data collection and analysis are used in the research –an associative experiment, open-ended questions and observation. As a result of the associative experiment main factors of adaptation of foreign students are revealed: interest in Tomsk, comfortable accommodation, professional tutors, relationship with peers and Russian language level. Weather and the need to adjust to new surroundings negatively influence adaptive capacity. Analysis of answers to the open-minded questions has confirmed the results of the associative experiment. Negative character traits are mentioned as factors that negatively influence adaptive capacity. The Russian language is regarded ambivalently by the Chinese students. It is perceived both as a negative and as a positive factor by the same respondents. Many students consider successful passing of Russian as a Foreign Language Test as personal success. Therefore, Russian is the most important factor of adaptation of the Chinese students in TPU

01.00.00 Physical-mathematical sciences
Description
The steady increase in demand for isotopes requires the development of methods to increase the efficiency of isotope separation technologies. Methods of isotope separation based on thermodynamic differences of isotopic forms of the molecules don't require significant investment, but characterized by a low rate of exchange. It's known that the magnetic effect leads to a change the vibrational frequency of the molecules, and therefore their thermodynamic parameters. The change increases the thermodynamic parameters, including the exchange rate. The results of the experimental determination of the thermal effect of dissolving the salts of NaCl, KCl, CuSO4, sodium amalgam decomposition by distillate in a magnetic field and without field were shown. Magnetic interference can have a significant effect on the amalgam exchange method which was shown by quantum and mechanical analysis of the results
