Band structure calculations were performed for quasi-2D MeO systems using the pseudopotential method within density functional theory. The calculations were carried out within the plane waves methodology using pseudopotentials. Density of electron states was calculated within the approxination of collinear magnetism. We examined the electron structure and estimated the electronic and magnetic properties of FM-ordered quasi-2D MeO systems (Me = Mn, Fe, Co, Ni). It has been demonstrated that the MnO - FeO - CoO - NiO row exhibits a shift in 3d spin down states of the metal relatively to the Fermi level towards the low-energy region. The above affects magnetization in 2D systems of oxides of 3d transition metals. The character of electron density distribution in quasi-2D MeO systems (Me = Mn, Fe, Co, Ni) indicates ionic bond type between the atoms in Me systems. The tendency towards increase of the band gap in the FeO→ CoO→ NiO row has been established. The obtained estimates of the local magnetic moment of a 3d transition metal atom in crystals of examined oxides correlate with experimental data. In conformity with existing views in physics, we have revealed the effect of spontaneous spin polarization of Me 3d and 2p bands of oxygen atoms in quasi-2D MeO systems (Me = Mn, Fe, Co, Ni), which in our opinion plays the main role in generation of magnetic moments in the atoms of 3d transition metal and oxygen.

To achieve high accuracy of measurement of liquid flow rate using the hot-wire gauges are encouraged to use multi-segment method of spatial characteristics of the transformation. The method is based on the nonlinear three-dimensional elements. Model the spatial characteristics of the transformation is maximally adapted to the peculiarities of the conversion function of the primary transmitter. Model repeats its spatial form with the non-linearity, zero drift, the influence of external factors, including temperature. This provides a low error rate calculation of flow. Study of the effectiveness of the method was based on experimental data obtained during the calibration at different temperatures. Maximum reduced measurement error does not exceed ~ 0.45% at an arbitrary temperature, recorded during measurement.

Nowadays many researches devoted to the problem of health of the individual, have become of a major significance. Scientific interest is high as there are many challenges and risks contemporary individuals face. Today we come across many publications where the health phenomenon is being analyzed from different perspectives. Questions of health are the subject of interdisciplinary research as a plenty of different sciences are involved into all levels, say, theoretical and applied. This article is some systematization of the results of two applied researches of 2014 in the frames of Southern federal university, Rostov-on-Don, Russian Federation. The main aim of the researches was to determine and describe the basic content of physical and emotional so called components of health of contemporary student youth and factors determining them. We questioned 232 students. Resuming some results we can say that because of contemporary needs of the society students have to put getting good education and career escalation as the main priorities in their life. They also worry about problems of ecology and health. In particular smoking and alcohol drinking. Our results again coincide with the results of other researchers that there is no gender difference here: both young women and men tend to smoke and drink alcohol – girls practice “men’s behavior pattern”. Students are stressed and that is the main reason of their drinking. They underline determination of some social factors, as political situation, changes in the Russian society, etc. Sociologists are expected to research mentioned problematic field more thoroughly.

Substantiated the technique of monitoring the state of the cultural complex of the city or the subject of the Russian Federation, based on sentinel populations. The study was conducted among the students of the 2nd year RGSU. As an integral indicator of the development of the cultural complex and the its individual components, use one of the cultural components of the group setting - the level of emotional perception of the relevant components. Normalized between -1 (total rejection) to 1 (absolute satisfaction). Primary data obtained questionnaires, one of projective techniques - by Charles Osgood's semantic differential. Interpretation of the results carried out on the basis of the theory of perception Information respondent suggested Coombs - ideal point model. Levels of perception are calculated in the linear approximation, as well as in the non-linear model, which we developed based on the concept of typicality, in terms of the theory of catastrophes. In contrast to the conventional approach of technology of semantic differential, calculations are performed not by the average semantic portraits, and by individual, using multi-agent modeling package Any Logic. Ultimately, calculated the distribution of function level of emotional perception of infrastructure and cultural life of the city as a whole on respondents. It is shown that the distribution function of the level of emotional perception of cultural infrastructure and cultural level of the city as a whole is almost the same. It was found that the emotional perception of the students strongly smeared cultural infrastructure, from strongly negative (-1) to a significant positive (+0.8). The main result - shows prospect the offered technique for assessment of development of the cultural infrastructure of the city as a whole, and for the analysis of cultural deprivation separate groups of the population.
