A new method of treatment of patients with chronic prostatitis and sterility by means of ultra-high frequency (60 W) electric field applied bitemporally has been proposed. During treatment 82% of the patients showed an increase in the number of spermatozoa in 1 ml of ejaculate; the percentage of movable and morphologically normal spermatozoa has increased. Patients with chronic prostatitis and sterility showed in the prostatic secrete before treatment a predominance of B-lymphocytes over T-lymphocytes. After treatment the number of T-lymphocytes in the prostatic secrete increased and the content of B-lymphocytes decreased. In the subpopulation of T-lymphocytes the content of T-suppressors increased, the content of T-helpers and O-lymphocytes decreased. At the same time patients with sterility showed an increase in blood testosterone level and an FSH decrease. Out of 67 wives of the patients with sterility 50 reported pregnancy within 6 months after beginning of the treatment.

The study of an astatic compensating gyrocompass, built on the basis of a modulation micromechanical gyroscope (MMG) of a hybrid type, has been carried out. A kinematic diagram is given and the principle of operation of the device has describing. The device uses the modulation principle based on obtaining information about the angular motion of the rotor and creating control torques in a rotating coordinate system, which makes it possible to exclude such a significant disadvantage of MMG as "zero offset". A feature of the gyrocompass under consideration is the use of two channels for controlling the rotor of the MMG, namely: a channel for the formation of a guiding moment, striving to combine its main axis with the direction of the true meridian and a channel for compensating this guiding moment. A linearized mathematical model has building, on the base of which an effective algorithm for the operation of a compensatory astatic gyrocompass is proposed. The device under consideration can be used to determine the true azimuth of the longitudinal axis of a mobile ground object, it has a higher measurement speed compared to devices built on three-degree "heavy" gyroscopes, and has good resistance to external influences (vibrations, shocks, etc.).
