FORECAST OF THE AGRICULTURAL DEVELOPMENT FOR THE AMUR REGION
DescriptionThis article explains the relevance of evaluation of agricultural growth, which can be achieved through the implementation of agricultural sectors’ innovative potential. The opportunities of agricultural growth are defined by the set of macroeconomic, sectoral and regional factors as well as the type of enterprises that have different levels of innovative susceptibility. The authors give an overview of the main methods of social and economic forecasting and justify the choice of the ARIMA (Autoregressive integrated moving average) as a tool for forecasting regional development of agriculture. The article presents the experts’ estimatesbased values of integrated indicators of agricultural exogenous factors and the ARIMA-parameters based on the use of these indicators for time series prediction of agricultural production in the Amur region. The authors conclude that the time series ARIMA-model of the gross agricultural production, taking into account the influence of innovation potential factors, demonstrate a good approximation to the Amur region data. This article also compares the forecasts of agricultural production on inertial and innovative scenario for the Amur region, and provides an estimation of innovation potential growth of the agricultural branches

CHALLENGES AND TECHNICAL SOLUTIONS OF USING HIGH-PERFORMANCE TRANSPORT OF AGRICULTURAL MACHINERY
DescriptionMaterial and technical resources form a large part of the costs in agricultural production and determine the level of intensity of agriculture, productivity and competitiveness of the industry. The most important role in agricultural production is played by transport operation, from productivity and quality of which directly depends the volume and the grade of final products. More preferable is tractor transport, particularly for on-farm transport, taking into account the impact of navigation systems on the ground. Continuous growth in the saturation of tractors carried out around the world, improves the performance of tractor transport aggregate by increasing their capacity and speed, either on the road or in the field. However, if you increase the saturation of tractors, it encounters problems related to the deterioration of the controllability of the tractor and transport unit. The reduced controllability leads to an increase of damage to transported agricultural products owing to increased oscillatory processes in the system of "road – trailer – tractor – operator" when driving on-farm trails, deteriorating the smoothness and braking properties. Especially sharp these questions relate to transportation of easy-to-damage agricultural products at farm transportation. The feature of data traffic lies in the sharp drop in grade products (products receive numerous mechanical damages, deteriorating its quality, and lose marketability and accordingly reduced its cost). Influence on fruit and vegetable products of unfavorable factors can lead not only to a dramatic loss of quality at the time of transportation, but also reduce the resistance during further storage. To solve the problems emerging when increasing the saturation of tractors, we have proposed devices, allowing reducing negative impact on the production of elevated oscillatory processes, to increase the permeability and straightness of movement of tractor-transport unit

01.00.00 Physical-mathematical sciences
DescriptionThe article presents the theory of the electromagnetic type of rocket motor. The apparatus consists of a magnetron and a conical cavity in which electromagnetic oscillations are excited. We explain the mechanism of trust in such a device based on Maxwell's theory and the Abraham force. We built a dynamic model of the motor and calculated the optimal parameters. It is shown, that the laws of conservation of momentum and energy for the rocket motor of electromagnetic type are true, taking into account the gravitational field. In simulation, the movement used the theory of relativity. The source of the motion in an electromagnetic drive is the mass conversion in various kinds of radiation. The optimization of the operating parameters of the device is done, namely by the excitation frequency, the magnitude of heat losses of electromagnetic energy by thermal radiation in the IR spectrum, the parameters of heat transfer and forced from the temperature dependence of the resistance of the material of the cavity walls. It was found that the effective conversion of electromagnetic energy in the trust force necessary to minimize the deviation of the excitation frequency of the primary resonance frequency of the cavity. The mechanism of formation of trust under change the metrics of space-time, taking into account the contribution of the Yang-Mills theory and electromagnetic field tensor of energymomentum has been proposed

LEGAL ANALISYSIS OF SOCIAL SECURITY LAW IN RUSSIAN FEDERATION AND THE FEDERAL REPUBLIC OF GERMANY
DescriptionThe authors analyze the issues of the legal and economic problems of social security governmental regulation in the Russian Federation. In order to identify and subsequently find theoretical and practical resolution of conflicts and flaws in the domestic social security law, the authors propose to analyze the social institutions of the Russia and to match them with the existing social institutions of the Federal Republic of Germany in view of their historical closeness, belonging to one family of law, and the similarity of the legal foundations of the constitutional system. Comparative analysis of various aspects of life quality according to Russian and German data, which was examined above, leads to the conclusion that the primary task in this country is to restore revenues and stimulate the population’s solvency. The study of the social security issues led to the conclusion that the state social insurance is intended to replace the income lost due to certain events such as unemployment, illness, disability, old age, accident-at-work insurance. The authors conclude that there is need to improve the current Russian pension legislation, social security and social legal guarantees

NOISE-IMMUNITY OF PSEUDO-NOISE SEQUENCE ACQUISITION ALGORITHM FOR MC-CDMA COMMUNICATION SYSTEMS
DescriptionThe goal of the study is to research a noise-immunity of pseudo-noise sequence acquisition method for multicarrier communication systems MC-CDMA, using a segment of the pseudo-noise sequence. The goal was achieved by running a simulation developed in MATLAB. By analyzing the results, we can show that the developed mathematical model produces the lower bound for pseudo-noise sequence acquisition probability. The resulting analytical estimations might be used during the design phrase for pseudo-noise sequence acquisition systems for MC-CDMA based military communication networks

PAINTINGS BY S. A. GAVRILYACHENKO, AS ILLUSTRATIVE OF THE SOURCE ON THE DAILY LIFE OF THE COSSACKS
DescriptionIn today's world, one of the most urgent problems is applying to study history of everyday life. In this paper first analyzes the reflection of the everyday life of the Cossacks on the paintings for S. A. Gavrilyachenko. The author examines in detail the work of the artist associated with this theme indicates strengths and weaknesses. Particular attention is paid to the precision display of the Cossack everyday life in the artist's canvases. Based on the study, the author comes to the conclusion about the possibility of using S. A. Gavrilyachenko as one of the sources in the study of Cossack life. The work particularly focuses on the specifics of their use is indicated method of analysis of illustrative sources. The article also highlights the daily life of the Cossacks. The paper identifies features of life and development of the Cossacks, is indicated by its role in the history of Russia. Important place in the life of the Cossacks took the Orthodox faith; they very strictly observe the customs, traditions and beliefs. Particularly tragic was the Cossack period of the February revolution of 1917, at this time the destruction of the centralized management of the Cossack troops occurred. A decisive blow to the bar caused the Civil war of 1917-1923 and what happened during the famine of 1921 — 1922, this theme is most fully represented in the works of S. A. Gavrilyachenko

Description
The current state of the industry and high level of development of technologies dictates the requirements to various electromechanical converters of energy and electric drives. Constantly there are new requirements to these types of devices and their characteristics that lead to creation of more and more difficult devices of the electric drive and control systems which example is cascade systems of electric drives. This type of drives solves part of problems of the modern industry. However, creation of such devices requires development of new approaches to design and creation of cascade systems of the electric drive and its components where one of the most complex challenges is determination of parameters of electromagnetic system. In the article, a new approach is given, in finding electromagnetic parameters of components of the operated cascade asynchronous electric drive, proceeding from the applied types of the electric windings distributed in space. This approach is realized at creation of the program complex, which is part of system of automatic design

PROSPECTS OF USING INVASIVE LEGUMES IN HERBAL MEDICINE
DescriptionThe authors propose to consider alien invasive species as new bioresources. These plants form powerful (usually single-species) thickets in the secondary range and their size are larger than at the native cenosis. The territory occupied by invasive species, especially in disturbed habitats, is quite high, so their possible yield is very high. The main problem of using alien species in the pharmacological purposes is the lack of information about the dynamics of the chemicals accumulation. Available data on the biochemistry in its natural habitat is inadaptable for the same taxon in the secondary range because of significant microevolutionary changes. In this work we present the results of phytochemical screening four legume species, formed invasive populations in the Middle Russia - Galega orientalis Lam., Lupinus polyphyllus Lindl., Robinia pseudoacacia L. & Caragana arborescens Lam. Information about these species as traditional medicine plants is given. Original data on the concentration phenolic compounds and biophile silicon in leaves and inflorescences are presented. Information on the fractional composition of the flavonoid complex is done. Taking into consideration the high adaptability of invasive species, the chemical analysis of the samples from different ecotypes was made. It is shown that accumulation of bioactive agents & biophile silicon isn’t depended on the environmental conditions. Concentrations of polyphenolic compounds were at the average level in comparison with medicinal plants. Thus, the combination of flavonoid complex with biophile silicon provides pharmacological significance of studied species, and justifies the needing the further study of invasive plant species in order to create new herbal medicines
