Abstract The work is devoted to the experimental study of the ultra dispersed particles formation process, which is essentially a fundamental problem of heat and mass transfer in gas-droplet flows under phase transformation conditions. Various methods of generating and controlling the gas-droplet flow parameters are considered. The description of the created equipment and diagnostic methods for studying gas-droplet flows is given. The particle size distribution functions are obtained using an aerosol particle spectrometer. The possibility of controlling the parameters of ultrafine particles of water-soluble and water-insoluble substances (medications) formed under evaporation of microdroplets of solutions and suspensions is shown experimentally. An attempt to reconstruct the distribution functions of microdroplets and their average dimension from measurements of the parameters of ultrafine particles formed after complete evaporation of the droplets is made.

Using petroleum ether to extract the fermentative fluid (bio-slurry), then to get the inhibition mechanism of it, and infer which is the main component in inhibition mechanism of biogas. The conclusion found by the experiment is that fat soluble substance is better than water soluble substance in inhibition mechanism, and fat soluble substance is close to 75% biogas fermentation fluid, while water soluble substance is worst. That is to say, the main subject in inhibition mechanism is hided in the fat soluble substance.

The paper presents the results of studying the possibility of controlling the links of hormonal regulation of the reproductive cycle of cattle using silicon dioxide in an ultra-dispersed form to increase fertilization during frontal insemination. The aim of the study was to analyze the effect of silicon dioxide UDPs when used in the scheme for synchronizing the sexual cycle of heifers on the dynamics of progesterone, FSH and LH and the fertilization of animals from frontal insemination. The studies were carried out on breeding age heifers of the red steppe breed. We formed two groups by 10 heifers – the control and the experimental one. In both groups, the synchronization of estrus was carried out by double application of estrophan. In the experimental group, the animals were simultaneously injected with estrophan with a solution of silicon dioxide ultra-dispersed particles in isotonic sodium chloride solution (dose of silicon dioxide 10 μg/kg). Blood for the determination of hormones was taken from heifers on the 1st, the 11th and 14th days of the experiment. All animals were inseminated frontally with deep-frozen semen by the rectocervical method. It was found that in the experimental and control groups, the dynamics of gonadotropins during the induced sexual cycle was similar; however, the LH level before insemination in heifers of the experimental group exceeded that in the control by 0.81 ng/ml (34.4%). Fertility of heifers in the experimental group was 70.0%, in the control – 50.0%. The effect of silicon dioxide in the UDP form on the dynamics of sex hormones and the fertility of heifers from frontal insemination during estrus synchronization was studied for the first time.

Adaptive Capability

Experimental study on the growth and development of saline and non-saline populations of Eclipta alba Hassk., planted on soils artificially salinized with water-soluble salts of sodium and a saturation extract of saline soil, revealed differences in their salt-adaptive capabilities. The relatively higher salt-adaptive capability of the saline population both at germination and subsequent stages of growth indicated ecophysiological differentiation within species due to salt stress.
