Description
The present study was carried out in the view of the fact that there is no more or less complete theory of time series prediction memory to date. This determines the urgency and necessity of the development of new mathematical methods and algorithms to detect possible potential predictability of the series with the memory and the construction of adequate predictive models. Classical methods of forecasting economic time series are based on the mathematical apparatus of econometrics. It is carried out basing on the assumption that the observations that make up the projected time series are independent, whereby to perform the necessary subordination of the normal law. The latter, however, is the exception rather than the rule for economic time series that have so-called long-term memory. Toolkit implementations of nonlinear dynamics were the new computer technology that made it possible to study complex phenomena and processes “on the display screen”. The proposed approach differs from the classical methods of forecasting by the implementation of a new accounting trends (evolution of centers and the size of a bounding box), and is a new tool (phase portraits) to identify the cyclical components of the considered time series

POWER AND HUMAN'S FREEDOM INTERACTION IN CONTEMPORARY WORLD
Description
Hereby we substantiate the necessity of social philosophical analysis of power phenomena as due to power relations' change a human being and his values also transform. A knowledge convertation into power recourse has become a reason for authority humanization and democracy thus leading to total humans enslavement. People's intentions in aims achievement, their effectiveness and high level of organization let the authority not only manage them but also produce «obedient bodies». The authority area or in other words «focused» territory, or already experienced human activities and existing terms grow and widens. New social benefits and mobile shapes disconnected with «place» and territory appear. Thus, the «authority deterritorization» leads to the responsibility refusal for any actions and effective management consequences. New authority shapes start being exhibited as total control abolishment, where a person gains absolute choice of freedom solving his vital problems but without being supplied with choice bases. In today's world an authority, whose mission is to protect humans from anarchy, chooses risk as a new management paradigm. The mentioned reasons' entity depersonalizes the power relations where not only subordinates but also authorities become impersonal, where «authority subjects disappear». The contemporary authority research works by Alvin Toffler, Michel Foucault, Sigmund Bauman, focusing at power relations, determine the authority nature as an indefinite, newly shape taking and remoted from its final research definition

Description
The development of laboratory setup is connected with a necessity of designing and experimental investigation of equipment examples for innovative energy efficient system of agricultural enterprises off-line power supply on the basis of helio moduluses and is stipulated by needs of efficient heat electro supply of agricultural enterprises working in climatic regions with low and short-term solar activity. Operating regimes, matching and justification of necessary elements for the construction of the energy efficient helio system and the most efficient their arrangement are determined based on preliminary experiments. Geographical location of agricultural enterprise (the principal checkpoints should be insolation intencity and solstice angle typical for the region) and social-economic development level of the region should be taken into consideration at forming demands to the constructions and abilities of heat water supply helio modules. The necessity of investigations at laboratory setup with artificial heat sources, simulating solar heat, is explained by impossibility of experiments’ carrying out in the real nature conditions, notably because of weather inconstancy and climate in tote, because of impossibility of setups exact placement on ground location, because of helio collector’s modes of operation limitation by the range of solar activity only in the investigated region etc. The list of technological parameters and helio water heating process factors, which are measured and controlled during the experiments, is built into the designing of the setup. These parameters are based on the statistical data given by meteorological stations of late years. All that will ease the designing of manufacturing helio collectors and will allow to get more precise information, oriented to the maintenance of energy efficient equipment in different zones of researched region with highest possible usage of their potential. With a glance of foresaid, we have designed the laboratory setup for the experimental investigations of the module solar collectors’ elements

TO INFORMATION SYSTEMS DEVELOPMENT FOR A MILK PRODUCTION ENTERPRISE
Description
In this article, we have explained the necessity of creating precise adaptive energy-saving technologies for use on the milk production enterprises. There are defined the main problems that reduce the enterprises efficiency and milk quality. Many of these problems can be solved if there is organized correctly the information flow through the creation of complex programs and databases. Regardless to the size and structure of the milk production enterprises, they have the following main information streams: animal productivity data; information about the herd composition and structure; information about the diet composition; information about the quality of milk and others. For the storage of this information there is a developed database consisting of 66 tables and 10 diagrams. The article includes information on some charts. To meet the challenges of manufacturing processes modeling there was offered a bunch of "Mathematical package - Database Management System." Within the developed automated enterprise management system we have selected MATLAB and MS SQL Server. There are presented models of thermal balance; heat generated by animals; heat loss from the feed coming from outside and so on. We have also grounded the applicability of the structural processes modeling in conjunction with the possibilities of modern database management system that allows you to convert a wide range of energy saving tasks to automated analysis and forecasting. This approach has the modularity and implementation ease, all of which allows you to build complex information systems, which at the same time are easy to change, expand and renovate

BIOLOGICAL AND PRODUCTIVE RESOURCES OF LACTATING COWS AT DENITRIFICATION
Description
The article presents the results obtained in the process of two scientific-practical experiments carried jut on two milk cows (Shvitskay breed) aimed at the antioxidants detoxication properties and mould inhibitor revealing. This factor is actual in the Republic of North Ossetia-Alania as the intensive technologies of the fodder crops cultivation using the nitrate fertilizers are widely applied in the region leading to the excess nitrates and nitrite penetration into the animals’ organism. During the first experiment, the antioxidants of epophen and vitamin C were added into the ration of the lactating cows with the subtoxic dosage of nitrates both separately and in complex. The complex feeding proved to increase the milk productivity, the fat mass and protein mass in milk while reducing the fodder expenditure per product unit. Beside, the lactating cows revealed the digestive and intermediate exchange betterment and the reduction of nitrates and nitrites level in blood. The second experiment helped to study Khadoks antioxidant and mould inhibitor called Mold-Zap efficiency use for the nitrates and aflotoxicin B1 detoxication. The researches showed that the complex admixtures of the said preparations introduction into the rations of the animals increased the milk productivity, fat and protein content and reduced aflatoxineM1 content. The cows activated the digestive and intermediate exchange, accompanied with the nitrates and nitrites level reduction in the organism

Description
The article presents the results for the study of productivity and quality of vegetable crops in irrigated chains of crop rotation by using intermediate and green manure crops. The greatest number of units of grain produced in the first variant of the experiment, where in a part of crop rotation cultivated sweet corn, mustard as a green manure for potato and onion planting summer planting seeds in the ground and reached 37.4 tons of grain units. The infection of potato tubers with complex disease was lowest at the control variant and compose 11 %. The highest infection with diseases of potatoes fixed at the intermediate and without the use of Side-General culture and was 18 %, which is 63.6 % more than the control options. When we are using intermediate crops diseases of onion increased by 7,7–15,4 % in case of green manure using. When you include treatment of the soil under the previous culture it was the largest infest with diseases and was 16–17 %, which is by 23.1 and 30.8 % higher than in the control variant. Based on these results, we can conclude that the use of green manure crops and intermediates more favorable effect both on the productivity of the subsequent crops or the quality and marketability
