TECHNOLOGY FOR PRODUCTION OF PROTEIN-CONTAINING RAW MATERIALS FROM THE PRODUCTS OF SUNFLOWER SEEDS
DescriptionCurrently, secondary resources of vegetable raw materials are widely used in solving the food, environmental and energy issues, as well as an additional source of substances of natural origin. A significant amount of secondary resources is produced during the processing of sunflower seeds - the main oilseed Kuban. Fats industry, while processing seeds, mainly extracts only one component - vegetable oil and is having a huge amount of meal, which is mainly used for agricultural purposes. Valuable property of sunflower meal is that it is high in protein, low cost and lack of toxic and anti-nutrients. Favorable amino acid composition determines the viability of recovering proteins from sunflower meal. Proteins were extracted from sunflower meal with a dispersing agent which may be water, sodium salts, alkalis, acids, or any organic solvent, followed by precipitation of the protein at the isoelectric point with hydrochloric acid. However, this protein has a high content of phenolic compounds, which gives it a dark color. The high concentration of chlorogenic acid in sunflower meal and its ability to form a dark colored complex with proteins limits the use of sunflower proteins in the food industry. All known methods of protein purification products from phenolic compounds, in particular chlorogenic acids, are mainly aimed at reducing the use of solvents and washing using membrane technology. However, in most cases, their use is either inadequate due to removal of phenolic compounds or decreasing the nutritional and biological value of the obtained product due to the toxicity of the solvent used, and an inability to completely remove it from the protein

ANALYSIS OF OPENERS OF SEEDERS IN RESOURCE SAVING TECHNOLOGIES OF GRAIN PLANTING
DescriptionWhen sowing grain we apply resource saving technologies-technologies such as «no till» and a technology called «mini-till». «No till» involves planting crops on untreated surfaces. "Mini-till" is designed for the planting with minimum tillage. During the movement of the sowing unit on these agricultural backgrounds we can see working bodies tipping out. Stabilization of the drilling depth is ensured in two ways - by moving part of the weight of the planter on the opener or the installation of ballast weights. Openers of grain drills for resource saving technologies for grain crops can be divided into three groups – foot, disc and anchor. Disc coulter has varieties – single disc, double disc and montesquiu coulter. To analyze the cost of power for the operation of the opener, the following indicators – the minimum engine power of the tractor on the coulter and engine power of tractors per unit of working width. The calculation of the indicators was conducted using data the technical specifications of the planter. Snow coulter drill AGRATOR4800 provides a wide spread planting strip of 10-15cm. The minimum power of the engine of the tractor on the opener is 7.5 HP minimum power of tractor engine per unit of working width 25 HP/m. Double disc opener planter Great Plains has a minimum engine power of the tractor on the opener 2.7 HP and per unit of working width 26.0-28.44 HP/m. Planter equipped with disc knife for strip tillage. The planter Condor 1201 is provided with a chisel opener «ConTeC». The engine power of the tractor on the opener of the planter is 4.58 HP, the engine power of the tractor unit working width constitute l8.33 HP/m. This grain seeder has reduced power losses and provides sowing with a «no till» technology

MEANS OF SMALL MECHANIZATION AS A BASIS OF MODERN PFF AND PBF IN SMALL FORMS OF MANAGEMENT
DescriptionThe support and the development of small forms of management in agroindustrial complex of the Krasnodar region is one of the priority trends in development of agriculture of our region and country in whole. Especially it is actual in last economic events and restructuring of economic balance concerning to the financing of AIC in our country. In the article there was a question of importance of small mechanization means in limits of use of PFF and PBF as forms of import of replacement in modern economic conditions. There was presented a replacement of manual labor with mechanical one, use of less powerful energy sources such as minimotocultivators and tractors to 1,4 t.s. and there was touched the question of use of small mechanization means in the conditions of limited space with the application of highly productive hinged equipment. There was considered the question of influence and use of small mechanization means in small forms of management, there were shown the problems of provision and restructuring of park of machinery and transition on new technology with the use of less powerful means of mechanization in detail.

Description
The dynamic development of information technologies in medicine of the Krasnodar region, associated with the introduction of modern information systems in healthcare for 2011 - 2014 years has an impact on the system of issuing and servicing preferential recipes and prescriptions for controlled drugs. The introduction of a fundamentally new system of health care based on modern standards, common to the whole territory of the Russian Federation could not be possible to implement without providing healthcare organizations the tools to monitor indicators of prescribing beneficiary drug coverage (BDC) transmitted electronically to pharmacies. In supplying all the participants of the program with the necessary drugs (ND) in the Krasnodar region there is an urgent problem and visualization of information of BDC activities. Improving management by improving the efficiency and reliability of the information for all levels of management in a hierarchical structure of health is directly related to the quality of social services for certain categories of citizens in accordance with the Federal Law issued on July, 17th 1999 178-FZ "On state social assistance." This paper describes a methodology for the creation of a single automated database, which can be placed in both the private secure cloud and in the public, with the possibility of access to information in the workplace using the Internet. Working with a database is implemented by means of language T-SQL. Access to the system of end-users is implemented with taking into account the information security by means of the technology called "thin client". As an application, we use the Services Reporting Services - Reporting server platform that provides opportunities for convenient work with reports of various data sources. The database is filled according to the information of the state health care budget "Medical Information and Analytical Center" of The Ministry of Health of the Krasnodar region. We have also solved the problem of the processing of personal data by the method of introducing their depersonalization identifiers
