Description
We have presented a methodology for the optimization of technical parameters of the complex based on a solar system combined with a wind generator according to the criteria of efficiency and consumption of materials

STUDY OF SALT WHEY TREATMENT WITH ELECTRO DIALYSIS
DescriptionThe results of the effect of the electro dialysis treatment on the composition and properties of salt whey are presented. The main regularities of the demineralization process of salt whey and its efficiency are determined
-
Description
Solar collectors of helio water heater with ramified surface were developed. We have made an energy estimation of helio unit construction and enhancement of the efficiency of its work because of multiple reflections of solar fluxes
-
Description
We have made energy estimation of absorbed solar fluxes with a glance of diffuse insolation which passes through double- glazing unit to the right-angled planar radiator. While designing the model it was conceded to assume that direct solar radiation is the radiation of a point source

THE PROSPECTS OF USING OZONE IN THE DAIRY INDUSTRY
DescriptionThe article presents the regression model of the effect of ozone-air mixture in the contamination of test bacteria and bactericidal treatment technology for whey drinks

ESTIMATES OF THE INTENSITY OF ARTIFICIAL LIGHTING OF A LED IRRADIATOR OF LETTUCE IN GREENHOUSES
DescriptionCurrently, artificial irradiation of lettuce seedlings is produced with gas discharge lamps that have a low energy efficiency and a significant proportion of the spectrum in the green region. LED chips can be chosen in such a way as to ensure maximum photosynthesis of lettuce with optimal consumption of electrical energy
-
Description
The mathematical model presented in this article allows you to choose rational values and ranges of design and technological parameters of body separation, as well as their further optimization

DANGEROUS AND HARMFUL IMPURITIES IN NATURAL AND DRINKING WATERS
DescriptionIn the article we have experimentally substantiated the quantitative measurements on the estimated parameters using a set of chemical tools for water quality assessment called NHS-voda

EXPERIMENTAL RESEARCH EFFORTS TO UPROOTING TREES AND BUSHES PLANTED
DescriptionThe article presents the methodology and the results of experimental studies to determine actual values of effort arising from uprooting trees and shrubs plan-tations in the Republic of Mari El. On the basis of experiments and regression analysis we have established the coefficients of the approximation-defining relation between the force and the diameter of the stem of tearing depending on the type of crops
