The modeling method of heat extension in a detail in the combined process of plasma spraying coating with electromechanical treating and cooling by water jet is worked out. It is shown, that water cooling essentially decreases detail surface temperature and forms more strong coating thank to reduction of inner strains in the coating
The article considers perspective – compromise-and-rent strategy of the distressed loans management, Author gives several schemes of financial payments of enterprise to bank on the rent approach basis, economic-and-mathematical model, which determines optimal amount of the rent payment for enterprise-borrower and bank-creditor
The article is devoted to the development of a compressor
type ozonator. It describes the design of a
high-productivity compressor ozone generator, which
can be used for industrial decontamination of mixed
feeds, water, milk, and in the system of presowing
treatment of seeds. This construction allows generating
ozone with high concentration to 5 g/m3 at high feed
air or oxygen from the compressor station (up to 2000
l/min). The article describes the design of the basic
elements of tubular ozone generator, examines the
factors influencing the productivity of the ozonator.
The proposed mathematical model allows calculating
the productivity of the ozonator when considering multiple
influencing factors. These factors take into account:
the parameters of supply voltage, such as the
magnitude and frequency of the supply voltage; the
configuration and geometrical parameters of electrodes
such as, the area of the electrodes, the configuration of
the surface of the electrodes and distance between
electrodes; parameters dielectric barrier; and the transported
gas parameters such as volume, temperature,
pressure and composition. Special attention is paid to
the design of the electrodes made of woven wire mesh
with mesh sizes from 1.5×1.5 to 2.0×2.0 mm. It is noted,
that such electrodes allow obtaining the maximum
productivity of an ozonator, and they do not lead to
overheating of the dielectric barrier, and do not output
down the generator. In the same way, the article presents
the results of the mathematical modeling
of ozone generator productivity while changing
various factors

The article presents the characteristics of the mechanical composition of clusters, the chemical composition of grape juice and fresh grapes and wine tasting evaluation of three varieties of table. We have identified the following uvologic indicators of clusters of cultivars Flora, Nisina and Anyuta: structure - 90.0; 91.5; 87.3; addition - 8.0; 6.6; 10.8; structural - 6.4; 5.4; 8.1; berries - 17.6; 15.0; 10.4. In the studied berries of grape varieties the mass concentrations of sugars and titratable acids were in the range 18,1-23,5 and 0,73-0,78 g/100 cm3 respectively. The combination of sweetness and acidity causes high taste properties of grapes. In grape berries of Flora and Nizina the concentration of fructose was two times more than glucose. Differences in the content wine, malic, lemon and succinic acids in berries varieties of Flora and Nizina were insignificant. In the berries of Anyuta variety, the concentration of lemon and succinic acids was more, malic was less than other varieties. Most of the studied varieties of berries contain malic and wine acids. More of cations of potassium, sodium, calcium and magnesium then in other varieties and it contain less than Anyuta berries. The difference in the content of various cations in the berries of varieties of Flora and Nizina is negligible. Tasting score of fresh grape of Flora variety was 7.0, Nisina - 7.8 and Aniyta - 7.6 points
