Abstract . A self-consistent model for the dynamical and chemical evolution of dense interstellar clouds is examined. The model includes the basic atomic and molecular constituents of dense clouds and the reactions in which they are involved. ... The results of one-dimensional modeling of the early stages of collapse of protostellar clouds of different masses under the action of ultraviolet radiation are presented. Astrophysical applications of the results obtained are discussed. ...

... The antenna system . ... A military radar system, consisting of two identical radars, was transferred to the Institute of Solar-Terrestrial Physics (ISTP). ... The system features a two-channel transmit-receive antenna. ... By changing the phase difference in the channels, one is able to modify the shape of the total channels' beam in the angle-of-elevation plane. ... The total beam is controlled by introducing the phase signal into the excitation signal of one of the channels. ... Peak power.. ...
