THE HARDWARE SOURCES OF THE AUTOMATION OF THE SOLAR WATER HEATING OF THE AGRICULTURE PLANTS
DescriptionThe article deals with the necessity of the uninterrupted control of the work quality of the solar heating system. The advantages of the microcontroller systems, which gave their evolution in the last years, are shown. The possibilities of the usage of the microcontroller systems for carrying the work quality control are shown. The electrical principal scheme of the system of the automatic control of the solar water heating which allow to control the work quality control are shown. The system was divided into interconnected parts. The methods of the temperature control by the electronic temperature sensors 18B20, water control by the optical pair with open channel and water quantity meter with the optical wheel, water level in the tank by the ultrasonic sensor of the distance and level of the solar radiation by the pyranometer are shown. The necessarily calculation of the geometric tank sizes and water velocity in the solar collector are carried out. The corresponding hardware resources of the PIC microcontrollers like hardware counters, timer with the ability to allow counting by the external signal (Gate Control), analog-digital converter and fixed voltage reference module are described. The algorithms of the control of the water temperature in the tank and the control of the filling the tank with the hot water from the solar collector are described. The methods of the transmitting information to the operator are shown. The advantages of the microcontroller control are described

ANALYSIS OF EFFICIENCY OF ACTIVITY OF MANAGING SUBJECT OF VINE INDUSTRY
DescriptionFor the analysis of the effectiveness and the efficiency of entrepreneurial activity of organizations we apply a system of indexes, characterizing the level of the use of production resources: labor, floorspace, average annual cost of the combined assets, average annual cost of circulating assets, including supplies, average annual cost of own capital, production expenses, including financial expenses. As a quantitative result of activity of managing subject we use volume cost indexes, characterizing an effect: gross products are in current prices; profit yield from sales; gross revenue; income from sales; income to taxation; net income [1, 2, 3]. The high-quality indexes of efficiency of the use of production resources: gross products in current prices on an average annual worker; profit yield from sales on an average annual worker; gross. The analogical set of indexes of efficiency is applied, determining correlation of different types of effect and other resources. That determine an index, characterizing correlation of gross products in current prices and floorspace (in agricultural organizations we use 1 ga of lands, in point-of-sale – 1 m2 of point-ofsale area, in industry – 1 m2 of floorspace of factory, factory, workshop); correlation of profit yield from sales and floorspace; correlation of different. Then we determine indexes, characterizing correlation of different types of effect and average annual cost of the combined assets, correlation of different types of effect and average annual cost of circulating assets, production supplies, property asset, production expenses, and financial expenses. In obedience to methodical positions of analysis of indexes, characterizing the results of activity of managing subjects, we probe the dynamics of indexes for the last 3 – 5 years with the purpose of exposure of it. Important in research of indexes and efficiency of entrepreneurial activity is the use of factor analysis, allowing defining a quantitative measure influence of factors on the change of analyzable index, to ground backlogs of increase of efficiency. Most acceptable in the analysis of influence of factors there is a reception of chain substitution on the dynamics of indexes of efficiency of the use of production resources

Description
The system of indicators characterizing the financial condition of a commercial organization, the major thing is profitability of its operations as the ratio of profit on sales and revenues, the ratio of profit before tax and the average annual value of total assets, the ratio of net profit and the average value of all assets, net income and average equity. Great practical importance for the efficient management of resources economic entity is marginal analysis, but it requires, in our opinion, improvement. In the academic literature on management analysis it is recommended to determine the relative value of the stock of financial strength ratio of the absolute value of the stock of financial strength and actual revenue; financial headroom suggested determined by the difference between the actual value of revenue and earnings, the corresponding break-even point. The relative value of the stock of financial strength should be determined, in our opinion, the ratio of the absolute value of the stock of financial strength and the amount of revenue in the break-even point. Recommended in textbooks relative value of the stock of financial strength is a share of stock of financial strength in the actual revenue. The method of rating the financial condition of commercial organizations (credit scoring of the American economist D. Durant) return on total assets is also a priority index, largely determining the solvency and liquidity of the balance sheet, the financial stability of the business entity. However, in practice the profitability of the invested capital is not always characterized by an optimal investment

ACTUAL PROBLEMS IN ORGANIZATION OF FEEDING IN MODERN CONDITIONS
06.00.00 Agricultural sciences
DescriptionModern pig farming is a leading global livestock industry, but the organization of adequate balanced feeding is actual for the industry. Digestibility of metabolizable energy of feed depends on various factors, including the content of non-starch polysaccharides, which have a negative effect on the digestibility of key nutrients of the feed, lead to a decrease in growth rate and conversion efficiency of nutrients. Enzyme preparations which composition generally includes Xylanase, cellulase, β-glucanase activities, may avoid the negative impact of non-starch polysaccharides. Today's promising preparation that combines the functions of two feed additives - feed enzyme and probiotic, is an enzyme preparation Cellobacterin that, due to the particular organization of the enzyme complex, increases the digestibility of barley grain and effectively effects on sunflower meal. As a probiotic preparation it inhibits the development of pathogenic microorganisms and promotes the formation of beneficial microflora in the digestive tract. The introduction of Cellobacterin enzyme preparation into the compound feed with a high content of barley grain and sunflower meal increases the body weight of young pigs by 4.8% and reduces the cost of feed per 1 kg of live weight gain. The results of hematological studies found no significant deviations from the physiological norm in the morphological picture of the blood in experimental animals. The group, where Cellobacterin was added, showed higher vitamin A content by 2.8% as compared to the control, while vitamin E is found in both groups on the same level. Based on the results of the research to improve the productivity and growth rate in compound feed based on barley and sunflower meal with higher fiber content, it is recommended to include in the compound feed Cellobacterin enzyme preparation at the rate of 1 kg per 1 ton of feed
