Health of dairy cows ensures human health, so it is important that dairy products do not contain antibiotics that are used to treat any inflammation, including mastitis. In Russia at present, the problem of mastitis in cows exists with both attached and loose housing of cows. Mastitis of dairy cows are the great problem in milking husbandry. Losses from mastitis in milk yield can reach 15-20%. The main reasons for the occurrence of nonspecific mastitis of cows are the shortcomings of the working components of the milking machine: the degree of deterioration of the nipple rubber and the violation of machine milking technology (the reduction in pre-milking time and vacuum fluctuations account for 70% of all causes). Treatment of mastitis with antibiotics is effective, but not environmentally friendly and unacceptable. For the treatment of inflammation of the udder, it is necessary to use more environmentally friendly methods of treatment, one of which is the exposure to ultra-high frequency electromagnetic field tested by medicine. Use of three types of medical-mobile milking machines with the same method of exposure to ultrahigh-frequency electromagnetic fields on cow's nipples through electrodes in milking cups: LPDA-1-UHF, LPDA-2-UHF and LPDA-UHF-30 M, is described in the article. Author proved that cows with subclinical forms of mastitis recovered faster during milking with exposure to the ultrahigh frequency than when treated by antibiotics, and milking with the ultrahigh frequency device helps to recover 82% of the affected quarters with clinical forms and 100% of cows with subclinical forms of mastitis or with udder irritation. The high efficiency of the method of exposure to electromagnetic fields of the ultrahigh frequency during machine milking by means of medical-mobile milking machines LPDA-UHF for the prevention and treatment of mastitis of cows was shown.

On the foundation of the methods and mechanisms of electrochemical finishing with high-frequency group pulse we studied before, properties of the finishing process with ultrahigh-frequency group pulse were studied, effects of pulse effect on the finishing result were also researched. With the Ultrahigh-frequency group pulse power we designed, we designed a equipment with high precision and easy operation. After some single-factor experiments, we obtained the laws of how the main pulse influenced the result, from the Ra of 2Cr13 stainless steel surface.

We point out the peculiar form of the gravitational wave signal expected from a gas of particles carry spin-3/2 produced during preheating. Given the very few ways that gravitinos can manifest themselves in an experimentally observable way, we stress the importance of improving the sensitivity of ultrahigh frequency detectors in the future. This review is based on work that appeared in Ref. 1.

The paper considers the interaction of ultrahigh-frequency waves with moist grains, in which the moisture information is represented as a function of two variables: the attenuation and phase shift of the electromagnetic wave. Wet material is represented as consisting of three flat layers: water, dry matter and air. Based on uncomplicated calculations, the conversion functions are derived and the influence of moisture, temperature and density coupling forms on the error of moisture conversion is studied.

The article presents the structure of the method for the synthesis of microwave bandpass filters (BPF) on non-uniform lines, which makes it possible to select the structure and parameters of the BPF that provide the maximum length of the stop band to meet the requirements of electromagnetic compatibility (EMC) with given restrictions on the attenuation characteristics in the passband and barrier bands. and the established design and technological limitations on the drop in wave resistance and manufacturing tolerances. The results of experimental studies of the characteristics of ultrahigh-frequency bandpass filters with an increased protective band in order to ensure EMC are presented
