migration

The process of molecular diffusion penetration of components of mineral fertilizers into the soil was considered, as one of the possible ways of soil and groundwater pollution. Four mathematical models of migration of nitrogen fertilizers have been developed taking into account the adsorption of fertilizer components by the root system of plants and environmental conditions. Experimental investigations of the penetration of nitrogen fertilizer components have been carried out, on the basis of which the coefficient of molecular diffusion in sandy soils was calculated

The modern development of border areas of Ukraine is characterized by a number of features, which is connected with historical, geo-cultural, socio-economic factors of the organization of social life of their inhabitants. In the western regions, which are geographically close to the border with the EU, the European integration policy of the Ukrainian state has an additional effect on the mobilization of labor migration. High migration mobility of the population is not only a reaction of the regional community to higher European social standards.

VSP data processing workflow for determining of velocity model is being reviewed in the paper, which can be used for processing of seismic data. Optimal graph of seismic data processing is proposed. The graph contains all the optimal procedures, which allows obtaining seismic images of high quality. Seismic images, obtained after processing, were used for seismic interpretation, which helped to specify geological structure of the prospects in the cutoff part of the Dnieper-Donets Basi
