Opis:: The magnetophonon resonance in parallel transport of two types multiple quantum wells was studied. The transverse magnetoresistance was measured in pulsed magnetic fields up to 30 T (within temperature region from 77 to 340 K). A fine structure of magnetophonon resonance peaks which depends on temperature and does not depend on the type of multiple quantum wells, was observed. This effect could be attributed to two phenomena: contribution of barrier phonons and influence of thermostresses.

Opis:: In the work under presentation it was performed theoretical analysis of acoustic field influence on processes proceeding into two-component medium which is fog (waterdrops suspended in the air). Acoustic waves may influence on media where they propagate.Acoustic field, except for the fact that causes to accelerate waterdrop coagulation process, influences kinetics of phase changes: water – steam (gas). If gas medium is not steam – saturated enough then under acoustic field, evaporation of waterdrops suspended in the air follows. If then gas medium is steam – saturated enough so under acoustic field increase in size of waterdrops follows (fog condensation). In the both cases the change of waterdrop radius value is observed, suspended in the gas medium and this causes the change of its clarity. Under specific conditions these processes cause fog dispersal, then it is possible to use acoustic field as agent causing increase in atmosphere clarity.

Opis:: The presented study involves the problem of acoustic energy absorbed by aerosols. The aim of this paper is to present results of the valuation of ultrasound energy absorption general coefficient in the dispersions (aerosols). Aerosol particle is an obstacle for acoustic wave propagating and to surmount of which some energy of the medium vibrating is lost. Aerosol particle results in both acoustic energy scattering and its absorption. Besides, there are heat losses connected with periodic variation of the medium temperature. In this connection propagation of acoustic wave in the aerosol is related to decrease in wave intensity to more extent than in propagating a wave in a pure gaseous medium.
