Description
The study of the nature of many problems has to be the place in the economy of our country has revealed a lot of reasons and circumstances that trigger and aggravate them. Here you should pay attention to numerous gaps in the legislation, rooting the practice of finding and using such spaces, the lack of proper accounting and control over economic activity. Provided freedom of enterprise often rests on the inability of a large mass of participants of economic relations to solve everyday economic issues, to ensure a proper record of their activities, to present objectively the results of their work, to eliminate the appearance of contradictions. In the article the authors point to the need to change the mentality of business executives and companies in the direction of the inviolable observance of legally established and rules of business turnover. However, this requires a considerable amount of time and effort in following the course that is problematic. The authors point out that the solution of the problem may be the proposed accounting system based on an automated module with the established algorithms and patterns of economic behavior of business executives, which will rule out the withholding of economic ties, a reflection of unreal operations

Description
The role of transport in agricultural production is significant. It is the connecting link in the technological chain of the agro-industrial complex (of the APC). On-farm transport in the APC together with cars and tractor transport are widely used. The rationality of the use of wheeled tractors for farm transport substantiates the possibility of their movement on asphalt and on dirt roads. The specific gravity of the tractor transport in the domestic agriculture is 22-27% of the total volume of transport and 50-60% of the volume of farm traffic. A high level of use of tractor transport has been observed in the countries of Western Europe and the USA. In the farms of leading countries of Western Europe (Germany, Italy, France, etc.) about 70- 90% on-farm transport of agricultural goods is done by tractor transport. Tractor transport in a live environment is running on roads with varying terrain, a wavy profile cover, on soils with different hardness and humidity. When driving vehicles at high speeds, the trailer is wobbling from side to side, constantly accompanying tractor transport during its operation. As a result, it is bad for propulsion, transmission, and it deteriorates the dynamic performance properties of equipment, working conditions of the operator. To reduce the amplitude of oscillations of the trailer, the operator is forced to work strenuously with the steering wheel or to slow down the speed, which in turn affects operator fatigue, as well as the performance and maneuverability of the vehicle. Thus, advanced technologies in electronics, sensor technology and software will determine the nature of agro-technical innovations and will lead to increased automation of business processes in crop production with the aim to organize the work more effectively, efficiently, accurately, environmentally friendly and economically feasible. When working with intelligent technologies, understanding the development of high-tech, precision engineering requires a revision to the personnel policy and education in agriculture, which should be based on the relevant organization of farms and their proper new type engineering solutions

WORK AND MOTIVATION IN AGRARIAN SECTOR
DescriptionBased on a comparative analysis of the level of productivity in the agrarian sector of Russia and the leading countries in the world economy, the main trends and factors affecting the growth of this indicator were revealed. One the main reasons for low productivity is the technical and technological backwardness. In this regard, productivity gains can be achieved by improving the employment and organizational-technological innovation. We have comprehensively illuminated the problem of labor motivation. Based on our own researches and data from agrarian scientists the ways of its strengthening were traced. Also, there was highlighted highly motivated work in the family farms, which is not just a form of entrepreneurial employment based on private ownership of the means of production and the use of familial form of labor, but also the lifestyle of the rural man. We must not forget that the main motivation to work lies not only in its pay, but also in the education of people and traditions. It highlights the role of social support of rural youth and the need for radical improvement of social infrastructure. For the selfassertion of the individual, which is especially important for young men, the person should see a sense of ownership, initiative, independence, participation in decision-making and the distribution of income. These qualities are fully manifested in the family livestock farms and other forms of small business. Work on yourself is the most reliable social protection

DescriptionClassic quantitative measure of the reliability of the models: F-measure by van Rijsbergen is based on counting the total number of correctly and incorrectly classified and not classified objects in the training sample. In multiclass classification systems, the facility can simultaneously apply to multiple classes. Accordingly, when the synthesis of the model description is used for formation of generalized images of many of the classes it belongs to. When using the model for classification, it is determined by the degree of similarity or divergence of the object with all classes, and a true-positive decision may be the membership of the object to several classes. The result of this classification may be that the object is not just rightly or wrongly relates or does not relate to different classes, both in the classical F-measure, but rightly or wrongly relates or does not relate to them in varying degrees. However, the classic F-measure does not count the fact that the object may in fact simultaneously belongs to multiple classes (multicrossover) and the fact that the classification result can be obtained with a different degree of similarity-differences of object classes (blurring). In the numerical example, the author states that with true-positive and true-negative decisions, the module similarities-differences of the object classes are much higher than for false-positive and false-negative decisions. It would therefore be rational to the extent that the reliability of the model to take into account not just the fact of true or false positive or negative decisions, but also to take into account the degree of confidence of the classifier in these decisions. In classifying big data we have revealed a large number of false-positive decisions with a low level of similarity, which, however, in total, contribute to reducing the reliability of the model. To overcome this problem, we propose a L2-measure, in which instead of the sum of levels of similarity we use the average similarity by different classifications. Thus, this work offers measures of the reliability of the models, called L1-measure and the L2 measure, mitigating and overcoming the shortcomings of the F-measures; these measures are described mathematically and their application is demonstrated on a simple numerical example. In the intellectual system called "Eidos", which is a software toolkit for the automated system-cognitive analysis (ASC-analysis), we have implemented all these measures of the reliability of the models: F, L1 and L2

INTENSIFICATION OF CULTIVATION OF CHLORELLA WITH THE USE OF IRON NANOPARTICLES
DescriptionThe influence of reduced iron nanoparticles and its oxide Fe2O3 on the growth rate of Chlorella vulgaris IFR # S-111 added to the Tamiya nutrient medium is studied. In the range of concentration of additives 0-0,1 g/l (gram per litre) an oxide inhibited the growth of microalga already when its content in the environment 6,25*10-3 g/l. With the increase of reduced iron concentration in the first twenty-four hours in the whole range the growth of the cell concentration of microalga was observed. With a maximum iron concentration of 0,1 g/l the density of a chlorella exceeded the control for 70%, and in 48 hours for 150%. The microscopy hasn't shown morphological changes of a chlorella cells with addition of the nanoparticles to nutrient medium. Accelerated reproduction of the microalga cells became the result of the intensification of the photosynthetic processes, as indicated by the nature of the parameters of delayed fluorescence (DF) of chlorophyll and shapes of the induction curves. The maximum level of DF in all experimental samples after 24 hours of cultivation was significantly higher than the control, and photosynthetic activity increased with increasing concentration of nanoparticles. In 48 hours the maximum activity was observed at concentration of nano iron 0,0125 mg/l, then decreased. It shows that with an intensive growth of a chlorella the potential of nutrient medium was quicker exhausted that led to decrease in intensity of photosynthetic processes
