The invention relates to a technique for acting on dielectric substances, including breaking down solid bodies, particularly bodies having a low coefficient of absorption of electromagnetic radiation (rocks, building materials, etc.), and can be used in mining and construction. The method for plasma electromagnetic action on dielectric material consists in that plasma is generated by a plasmotron, a plasma flow is formed from the plasma and said plasma flow acts in a targeted manner on the surface of the material, the method being characterized in that the plasma is generated and a plasma flow is formed from the latter by a plasmotron having adjustable parameters, wherein a controllable flow of electromagnetic waves having a frequency of 0.5-5 GHz is additionally generated and is directed at the point of contact between the plasma flow and the surface of the material, and a temperature within a range of 3000-5000 K is generated and maintained in the skin layer of the plasma at the point of contact between the plasma and the surface of the material by means of adjusting the parameters of the plasmotron and/or controlling the flow of electromagnetic waves. As a result, an increase in the efficiency of breaking down solid dielectric bodies and an expansion of the scope of use are achieved.

The power assembly has a process schema comprising: a compressor unit (1); a heat exchanger (6); a receiver-collector (8); wave dampers (9); acoustic housings (10) made of a thermally non-conductive material; a flat bottom having ports located about the circumference thereof with the guide vanes of a turbine (14) mounted therein; a three-dimensional bottom (12); and a rotor (11) which has ports that coincide with the ports of the flat bottom. The vanes (17) of the rotor wheel of the turbine are mounted in the rotor ports. Gas is compressed in the compressor unit with the aid of injectors (4) and a compressor (2). The compressed gas is heated in the heat exchanger. The compressed gas is additionally heated in the bodies of the acoustic housings, where the gas is subjected to the effect of oncoming gas pulses which propagate in the gas at the speed of sound. The gas pulses impart kinetic energy to the gas, heating same. When in the automatic interrupter (18) containing the flat bottom with the rotor installed thereon, the ports of the rotor and the bottom coincide, the heated compressed gas passes through said ports, expands on the turbine vanes and, rotating the rotor and a shaft, generates gas pulses.

The invention relates to ophthalmology and is intended for preventing the onset and progression of myopia. A treatment course of action on the eye is carried out with a magnetic field, with transscleral low-energy laser radiation of a wavelength of 1.3 μm, and the eyes are additionally opto-reflexively exercised. The entire treatment course consists of 5 sessions on alternate days. Beforehand, badminton is played for 2 hours 3 times a week for 2 months. During the treatment course, badminton is played twice a week on treatment-free days. After the course of treatment is finished, badminton is played 2-3 times a week for 1 year. The method makes it possible to shorten the treatment period and reduce the number of procedure sessions for the functional treatment of near-sightedness, while increasing and prolonging the effectiveness of myopia prevention and treatment and rendering children more positively psychologically disposed towards treatment.

The invention relates to biotechnology, in particular to the production of bacterial preparations and foodstuffs, as well as to medical microbiology and may be used to identify strains of bifidobacteria. A method for identifying species and strains of bifidobacteria, based on the combination and polymorphism of genes of the toxin-antitoxin systems of the MazEF and ReIBE families, is proposed in the claimed invention. The technical result of the invention is as follows: performing amplification using the oligonucleotides developed, with the possible subsequent sequencing of DNA, enables the genotyping of bifidobacteria to be carried out accurately and quickly, including the typing of strains that are related to the В.longum phylotype. The oligonucleotides selected for such genes may be used for characterizing a strain and for ascertaining strain diversity in the ecological niche under examination. PCR with the use of these oligonucleotides may be envisaged as a diagnostic procedural approach for determining a strain under examination in clinical trials, or for the molecular tracking of a strain in commercial preparations for various existing diagnostic technologies and devices.
