It is found that when the increase in the relative inertia of the particles, decreases the coefficient of turbulent diffusion of the dispersed phase compared to the ratio of the carrier medium. Increase from-wearing leads to an increase of the coefficient of turbulent diffusion of particles. It is shown that the calculation of the coefficient of vertical diffusion of dispersed impurities ...

In the Pskov region, the continued decline in the area of cultivated land, the transition from focal to small-scale and dispersed types of nature use was noted. In the Kaliningrad region there is a repeated expansion of agricultural lands, the territorial structure corresponds to a large-scale type. The common pattern for both regions is the decrease in the sizes of the ...
