Opis:: The article discusses the impact of the agrarometeorological conditions on the state of soil and the processes connected with soil tillage and crop sowing. It determines agrotechnological reasons of technological adapting of these operations to enviromental conditions. It sets the terms of qualitative modifications in soil under the impact of agrometeorological conditions within spring and summer-autumn periods.

Opis:: A mathematical model for control by transient modes of gas flows in the long-distance gas pipeline is considered in the paper. The long-distance pipeline is considered in the model as the system of Line segments serially connected via compressor stations. Gas motion in such system is described by the non-linear system of equations of gas dynamics. In the frame of this model the integral parameters which determine the expenditure of energy and durations of the transient mode are introduced. These parameters can be used for formulation the problems for optimal control steady-state and transient modes of operation of main-gas pipelines.
