LED LAMPS FOR IRRADIATION OF GLASSHOUSE PLANTS
DescriptionAt present, much attention is paid to the production of domestic vegetable products. One of the main reserves of increasing the yield of vegetables is the production of products in sheltered ground. The intensive construction of new glasshouses and greenhouses complexes has sharply increased the demand for engineering facilities, with the help of which an artificial microclimate is created in the structures of the protected soil. To create high irradiations, a very significant specific installed power of photosynthetic radiation sources is required. Currently, advanced greenhouse plants use LED irradiation. The experience of these farms showed that LED irradiators have a number of significant advantages over discharge lamps: a significantly lower specific power of the irradiator; the service life of LEDs is several times higher; they do not contain toxic substances (mercury); LEDs are powered from a low voltage network, which is significant from a safety standpoint. Isolation of greenhouse plants from the effects of natural factors of the environment leads to undesirable consequences. The deficit of the amount of natural energy of optical radiation penetrating the structures of protected ground in modern industrial greenhouses during off-season is eliminated by additional artificial radiation from greenhouse lamps. In this case, the emission spectrum of lamps differs significantly from the natural one. This is especially true for ultraviolet radiation. The issue of creating an LED lamp for its application in structures of protected ground is considered. The main requirements for the creation of a photosynthetic lamp on the spectral composition of radiation are given. The necessity of a long-wave ultraviolet component in the emission spectrum of a lamp is substantiated

Description
The article describes the synthesis and verification of statistical and system-cognitive models of the influence of environmental factors on the quality of life of the population of the region. This stage of the ASC-analysis is performed in the system called "Eidos". As a result, we have created and validated (verification stage) all the specified systemic cognitive models. It is expected that reliability for the models of knowledge is sufficiently high for a given subject area, that is why we can state the discovery of a dependence of life expectancy and causes of death from environmental conditions. Typically, knowledge models are approximately 20% higher in accuracy than statistical models, which operate on the principle of positive pseudo-prediction. Making decisions based on the model of Abs (matrix of absolute frequencies) is not appropriate because of the different number of instances of classes (generalized categories) and dependence of the solutions of this amount. In the model called Prc2 (conditional and unconditional percentage distribution) the dependence of the model values of the number of examples in classes has been removed, but the accuracy of it is usually same low as in the Abs. In addition, for decision-making based on this model, one has to compare the values of conditional and unconditional probabilities manually, which is laborious and hardly possible for large dimensional models. The knowledge model called Inf3, based on a measure similar to the Chi-square, is the result of the automated comparison of values of conditional and unconditional probabilities presented in the model of Prc1, which is similar to Prc2, and usually has a fairly high accuracy, especially considering the high complexity of the subject area, which we simulated. Therefore, in accordance with the technology of the ASC-analysis data conversion into information, and afterwards - into knowledge, it is the model of Inf3 which is planned to be used for the solution of problems of identification, forecasting, decision-making and exploring the modeled subject area, through the study of its models

IMPROVEMENT OF A MULTILEVEL SYSTEM OF TRANSPORT LINKS OF FOREST ENTERPRISES AT THE REGIONAL LEVEL
DescriptionThis article considers the structure of the regional transport system of the forest complex, in which each mode of transport is characterized by a certain structure, technology of functioning and means. To describe the relationship between the parameters that determine the activity of a particular mode of transport, the production function method is used. Analytical dependence expressing the formal relationship between the parameters of various modes of transport is presented, the objective function of the organizational structure of the regional transport system management is presented, reflecting the efficiency of the entire transport system as a whole. The formulation of the problem is considered from the standpoint of game theory, in which there are four players with disparate interests: the organizational structure of the regional transport system and the three transport subsystems, each of the participants has its own control vector that belongs to the given set. We consider the case of full awareness, in which the hierarchical structure and all the objective functions of the system are known to the participants. The resulting statement of the problem is modeled by the game of four persons with conflicting interests. The game is viewed from the perspective of transport subsystems. To describe the relationship between the parameters that determine the activity of a particular mode of transport, the production function method is used. An algorithm for solving the problem is given

MODERN TECHNICAL EQUIPMENT FOR WORK IN GARDENS
DescriptionGardening is one of the high-value and highly profitable branches of agriculture. However, the level of fruit production in Russia still lags far behind the needs of the population: 20-25 kg of fruits and berries per year are grown per capita, which is a quarter of the minimum consumption rate. Currently, domestic gardening has a low efficiency due to non-compliance with the criteria of world production of fruits. The production of gardens is not competitive enough and does not meet the requirements of the highest quality categories of domestic standards. To increase fruit production, it is necessary to increase the level of intensification of fruit growing using the most valuable varieties and progressive technologies of cultivation. In this article, we consider devices for soil content in orchards, as well as for pruning trees - the main agrotechnical techniques in the technology of growing pomegranate crops that promote the production of stable, optimal harvests of fruit crops. The universal device of fruits is also covered, which makes it possible to reduce labor costs during the laying, care and harvesting of the fruit garden. The wide development of intensive technologies for growing fruits adapted to specific climatic conditions and ensuring a high level of competitiveness and profitability of production is one of the necessary conditions for the further development of gardening in Russia

ESTABLISHMENT OF THE RUSSIAN OILBANK PREMIER AS ONE OF WAYS TO INCREASE ENERGY SECURITY IN RUSSIA
DescriptionThe article deals with the energy security of Russia in conditions of sanctions and the globalization of the modern economy in the world community. It is substantiated that energy security is the main factor of political and socio-economic stability of each state. Russia is not an exception. For many years it has been the world's largest net exporter of oil and gas, mainly due to the weakness of the economic system, the main problems of the oil refining industry are considered, given The definition of energy security, the energy security of Russia is analyzed in the conditions of the crisis. An estimation of the export of domestic goods is given, the reserves of the regions are considered according to the level of extraction of oil resources, the rating of the largest oil companies is determined by the level of average daily oil production. It is concluded, that for a successful export, the redistribution of significant oil reserves between regions within the country will require a relatively long period, not one or two years. It was revealed, that the level of domestic production is not fully capable of providing consumers with the necessary products For which Russia implements the policy of modernization and reconstruction of the fuel and energy complex. Russia has been one of the leading oil exporters for many years, the main indicators of the oil sector have been examined, the definition of economic security and energy security has been defined. The energy security of Russia is analyzed in the conditions of the crisis, as well as the globalization of the world economy. A brief description of the energy security policy of the Russian Federation is given. An assessment is given of both the world oil sector and the Russian oil sector, based on this assessment, a conclusion has been drawn about the deteriorating conjecture of the oil industry. A correlation-regression analysis of the effect of oil prices on the quotes of the Russian ruble was conducted, and on the basis of the findings it was concluded that the Russian economy is in a sufficiently strong dependence on oil prices. The possible variant of reducing such dependence through the increase in the role of SPIMEX in the international arena and the creation of an oil benchmark in the Russian Federation is considered and described

DescriptionCurrently, personal subsidiary farms (PSF) have an important place in solving of the food security problem in some regions and the country as a whole. The organization of optimal and sustainable management strategy of maintenance for PSF should be planned according to the study of functioning of PSF. The authors propose a unified methodical approach for complex accounting of energy costs of external and internal flows involved in the production of agricultural products. Comparative energy characteristic of the functioning of the two personal subsidiary farms located in the Tomsk oblast and having different socio-economic and climatic conditions is presented in the article. Both farms are located in the taiga zone of Western Siberia. Calculations of the energy content of all the incoming and outgoing flows involved in the economic activities of PSF showed that the flow of technogenicanthropogenic energy is the most energy-intensive for both farms. Some conformity in the energy structure of consumption of their own product takes place despite the different types of stockbreeding specialization. An assessment of the level of selfsufficiency in food has shown that more favourable socio-economic conditions create preconditions for an increase of the anthropogenic flow. While PSF located in remote areas are forced to conduct of business activities with maximum using of natural resource potential
