Analysis of the Factors of Migration Attractiveness of the Volga Federal District Regions

Authors: Samonina S. S.

The article compares the significance of the factors of migration attractiveness of the Russian regions on the example of the Volga Federal District (VFD). It is shown that for a short period (2012–2015), there was a significant decrease in the number of factors attracting migrants, at the same time, migration situation in the VFD regions has also changed, sometimes drastically. The study was carried out using multivariate linear regression analysis.

Influence of the Continental Climate of the Lower Volga Region on the Quality of Grain Crops

Authors: Pryakhina S. I., Kadimikova A. K.

In the article to assess the continentality of the region’s climate at 10 stations in the Lower Volga region, the annual air temperature amplitudes were calculated, and the climate continentality indices were determined according to 5 formulas of different authors. The carried out calculation allows to allocate Zavolzhsky areas of the Saratov and Volgograd areas in region with as much as possible favorable conditions on cultivation of high-protein wheat. Presents the regionalization of the European part of Russia on the conditions for the formation of grain protein.

On the Possible Influence of Luni-solar Tides on Subsoil Gases Emission

Authors: Navrotckii O. K., Bogdanov M. B., Zotov A. N., Dotsenko A. M.

The possible connection was studied between the emission of various subsoil gases and the variation of the vertical component of gravity acceleration caused by the influence of the luni-solar tides. At negative values of tidal acceleration, the average concentration of methane and its homologues is reduced, accompanied by an increase in the average concentration of helium, nitrogen, oxygen, and carbon dioxide.
