Description
The article shows that for the essential oil industry of the Russian Federation to solve the problems of import substitution it is urgent to develop effective technology to extract fatty oil from the crushed and deprived of ether by water vapor coriander fruits. The existing technologies for obtaining fatty oils from deprived of ether coriander were considered. It is shown, that at small-scale enterprises it is most advisable to remove fatty oil by screw pressing. A brief analysis of main factors affecting the completeness of oil extraction in screw presses was carried out. The conclusion about the necessity of preparation of deprived of ether coriander for extraction with the purpose of increasing the yield of fatty oil was made. It is shown, that one of the stages of such preparation is the removal of part of the shell from deprived of ether coriander, which also increases the nutritional value of the oilcake. Fractional composition of deprived of ether coriander after extraction of essential oil by water vapour and drying was investigated by sieve analysis method. On the basis of obtained data, prior to separating the shell by pneumatic separation, it is recommended to separate deprived of ether coriander into three fractions by size – coarse (riddling from the sieve with the diameter of 1.8 mm), medium (riddling from the sieve with the diameter of 1 mm) and fine (undersize from a sieve with a diameter of 1 mm). Component composition of the coarse fraction of deprived of ether coriander was studied. It was found, that the content of the shell in this fraction is 36%, which indicates the possibility of its effective separation by pneumatic separation

The influence of technology on the fortification composition of biologically active substances of wine and the Cahors beverage type has been examined. We have also established and explained the dependence of the content of phenolic compounds, including carboxylic acids from the ways of alcoholization. A way of fortification, contributing to the enrichment of wines and beverages such as Cahors with biologically active substances has been shown

Description
The results of the study of amino acids of white table wines depending on the yeast strain, continuous contact of wine with yeast biomass and the presence of lees stirring are presented. The dynamics of amino acids, which affect wine organoleptic characteristics and the formation of wine defects, specifically, tyrosine, methionine, threonine and lysine is shown. Conducted researches made it possible to divide the amino acids into three groups depending on the carrying out the batonnage or lack of it. The first group consisted of amino acids, the concentration of which practically has not changed in the presence or lack of stirring. The second and third groups include amino acids, the concentration of which increased and decreased, respectively during batonnage. The stirring of the wine with yeast biomass facilitated to the activation of mass transfer processes between cell and medium, and the access of air lead to oxidation of some amino acids and the change of its concentration. The absence of stirring influenced to a slight increase in the concentration of such amino acids as cystine, cysteine, β-phenylalanine, serine, α-alanine, leucine and glutamic acid. The experimental data allowed to arrange amino acids in a row depending on the speed of release into the medium: ά-aminobutyric acid > glutamic acid > α-alanine > leucine

Description
The work is done in a scientific and practical ways to minimize power losses in the transmission of electricity in the interregional distribution networks from the sources to the consumer by the use of tasks, ensuring the gradual improvement in the support program, not only from the standpoint of the efficiency of reduction of transported power loss, but also due to a significant decrease the complexity of the calculations. The resulting shortage of electricity power associated with its transfer to the electricity networks, has demanded the need to find possible ways of reducing the value of electricity losses during transportation, both by improving and by optimizing distribution net-works schemes. Consolidation into a single set of electrical equipment, called the power cluster is connected to the sources of power and energy consumption, make better use of new principles of control technology and the transmission of electricity, on the basis of an automated monitoring system, ensuring the redistribution of energy flows and optimize them. The process of electric power transmission and reduction in electric power loss can be considered on the basis of linear programming problems, and their modification in the form of a transportation problem, and as a result, the transport matrix. On this basis, manipulating the data table, we can find acceptable solutions, well and then determine the best of them. As examples, this work has carried out the study on the basis of the three methods - "northwest corner", the method of minimum unit cost of electricity transport, as well as the method of the potential. The use of these three methods yielded acceptable solutions, to identify the most appropriate for the number of steps carried out at the decision, to reveal that the winner is the potential cost method

Description
The article is devoted to the development of high-tech metal-working industry, as well as to the use of unmanned technology. We recommended measures to improve the accuracy and quality of manufacturing of complex and large workpieces weighing up to 100 tons. To date, the technical level of many economy sectors is largely determined by the level of the production means. Based on the engineering development there is an overall automation and mechanization of production and industry processes, construction, agriculture, transport and other industries. We analyzed forms of slide sections, of errors affecting the accuracy of the workpieces manufacturing. We made simulation of the cutting forces and sliders deformations. Solved measures increase manufacturing accuracy based on multi-purpose machine tool systems of VM series. We held the analysis of the dependence of cutting forces, a slider form on its strain in different types of processing. We obtained a graph of cutting force and precision manufacturing. We defined the optimal shape of the slider cross section to increase the rigidity and reduce the slide deformation in metal cutting

FREE-COOLING IN SEASONAL COLD ACCUMULATOR
DescriptionOne of the traditional ways of reducing energy consumption is the utilization of seasonal cold accumulator which takes advantage of the geographical location of a country that allows, during the winter season, that is, November, December, January, February, March accumulates cold as a result of lower ambient temperature in these months. Significant amount of electricity is reduced as well as reduced operating refrigerant, which is harmful to the environment. The article presents determination of the size of cold storage with charging devices as chiller and dry-cooler. The approximate costs of the device operation as well as the time of assembly of these components have been obtained. The design of a seasonal cold accumulator is a system that brings a number of economic and ecological advantages. The seasonal tank design is a prototype of the chiller; it is smaller than the actual tank that will be selected for the highest hourly energy demand. This means that the actual device should be several times larger than the device that was used in the project. By selecting a small chiller and fewer refrigerants (mainly chlorofluorocarbons) called R- 410A, the environment would be saved from contaminants which are hazardous
