Software has been designed for forward and inverse modeling of natural self-potential (SP) fields which allows simulating the geoelectric patterns simultaneously for up to 29 sheet-like and prismatic electrostatically polarized conductors. The cross sections for a number of ore fields obtained by inversion with the new SPI-SV code (self-potential inversion, Siberian version) have been corroborated by later drilling and are consistent with reference geologic sections used in algorithm testing. SPI-SV simulation can provide high-quality assessment of mineral deposits and, furthermore, allows approaching global-scale investigation into the natural self potential of crust and mantle. © 2012.

Ice is a very complex and fundamentally important solid. In the present article, we review a new property of the hydrogen-bonded network in ice structures: an explicit nonequivalence of some antipodal configurations with the opposite direction of all hydrogen bonds (H-bonds). This asymmetry is most pronounced for the structures with considerable deviation of the H-bond network from the tetrahedral coordination. That is why we have investigated in detail four-coordinated ice nanostructures with no outer dangling hydrogen atoms, namely, ice bilayers and ice nanotubes consisting of stacked n-membered rings. The reason for this H-bonding asymmetry is a fundamental nonequivalence of the arrangements of water molecules in some antipodal configurations with the opposite direction of all H-bonds. For these configurations, the overall pictures of deviations of the hydrogen bonds from linearity are qualitatively different. We consider the reversal of all H-bonds as an additional nongeometric operation of symmetry, more precisely antisymmetry. It is not easy to find the explicit breaking of the symmetry of hydrogen bonding (H-symmetry) in the variety of all configurations. Therefore, this asymmetry may be named hidden. © 2014 American Chemical Society.

The theoretical and practical analysis of a problem of tolerance as a whole and a set of tolerant consciousness of young people in the Tyumen region is presented in the article. The results of the questionnaire carried out in settlements of the Tyumen region in spring and fall of 2013 are analyzed in this article. The conclusion that the tolerance level of youth in the Tyumen region is high and promotes strengthening of tolerance in our society is drawn.

At present, Russia faces a demographic crisis that threatens with an extinction of Russian ethnos. According to scientists, the reason inter alia, is in the deformation of the values system, expressed in the people's desire for individual achievement in the extra-familial field, egocentrism, reluctance to make a family and have children. The article presents the results of a study of value orientations of the people in Tyumen, summarizing these results, the author comes to a conclusion, that the process of value formation of the personality, with a shift towards the creation culture, the strengthening of family values and the institution of marriage, as well as having many children needs a systemic influence from the government.

We modeled the processes of growth and dissolution of small amounts of deposit on the solid electrode. Quasi-stationary diffusion method solved the basic problem of growth and dissolution of the semi-spherical nuclei deposit. Equations are obtained for current-voltage curves and chronoamperogram for reversible and irreversible electrode processes of electrodissolution of deposit nuclei. We have derived relations for the peak current and peak potentials of the current-voltage curve. © Springer-Verlag 2012.
