PHOTOVOLTAIC PLANTS: PROSPECTS, ADVANTAGES, DISADVANTAGES AND THEIR CHARACTERISTICS
DescriptionAnalysis of scientific literature has shown a promising direction in energy saving and in increasing of efficiency of power supplies remote from external networks in Russia is the application of solar photovoltaic power plants. The level of solar radiation on the territory of Russia varies widely from 810 kWh/m2 per year in remote Northern areas to 1,400 kWh/m2 per year in southern areas. We have revealed their main advantages and disadvantages of solar photovoltaic power plants, as well as the purpose, basic features, features selection and operation of inverters and batteries. We have also given a generalized block diagram of three types of solar photovoltaic power plants: autonomous, standby, network. The peculiarities of their work have been presented. To improve the reliability of operation of solar power plants we need to design them according to the modular principle. Modular aggregation has to be applied for stand-alone inverters, where the input and output filters, power electronic circuit and system voltage regulation and protection represent the functional module elements. It is possible to increase significantly the reliability of autonomous inverters and solar PV systems in the complex, using one-phase and three-phase transformers with rotating magnetic field in their design. The advantages and the disadvantages, the peculiarities of the solar PV plants discussed in the article will allow to develop their structural and circuit designs with improved maintenance characteristics in the future

FUNDAMENTAL LAWS OF RECOGNITION OF SOCIAL CATEGORIES ON ASTRONOMICAL DATA AT THE MOMENT OF A BIRTH
DescriptionIn the article the method and the results of investigating the information properties of the celestial bodies of the solar system are described. Is proposed the new for contemporary astronomy tool of knowledge, which includes intellectual information technology and the multichannel receiver distributed in the space and time, as which were used 20007 subjects. This allowed to open and to begin a study the new previously unknown phenomena of nature. It is in particular established that interaction of the group of subjects with the space environment has substantive nature. The reaction of each subject to the position of the celestial bodies of the solar system at the moment of birth was recorded and was processed for this. Each subject reacted via selection of one or several of 37 social categories, which composes totally 86314 cases. By statistical processing discovered, that the parameter of the dispersion of the information of the signs of celestial bodies (integral informativeness) depends on position of an ascendant - degree of the solar zodiac ascending in the east at the moment of a birth, and it depends on the distance to the celestial bodies as well. The mechanisms of the influence of celestial bodies on the group of subjects are discussed.

FUNCTIONAL BEVERAGES CONTAINING PECTIN ON BASED ON CABBAGE JUICE
DescriptionThe article presents data on the development of recipes and technologies for the production of functional drinks based on cabbage juice. Theoretical and experimental justification of the selection of ingredients of plant origin for the modeling of drinks with a high content of pectin substances is offered in the article. The use of carrots, beets and cranberries is considered as an additional raw material for the purpose of expanding the range and improving the organoleptic properties of beverages. The fractional composition of pectin substances used in the raw materials was studied. The expediency of introducing concentrates of pectin substances into beverage recipes, which define the functional properties of beverages and their optimal content in the recipes was determined. The characteristics of basic parameters of new drinks based on cabbage juice are given. The results of the study of the complex forming property of the developed beverages, which confirmed their functional orientation, are presented. Experimental studies have shown that the addition of pectin increases the complex forming property of juices. Complex forming ability of cabbage juice with beet pectin in comparison with the control sample and other samples is the highest. Taking into account additional complex of biologically active compounds based on cabbage juice, this product can be used as therapeutic, prophylactic and chemoprotective

THE COST AND LOSS FUNCTION IN THE RESEARCH OF MULTIPURPOSE ASSEMBLIES
DescriptionUsing the example of three multipurpose assemblies (MPA) we have presented the possibility of the cost and loss function appliance for the substantiation of the design and operating parameters as the criterion of optimization. The mentioned objective function of mathematical model is the sum of expenses on the performance of the scheduled amount of automated tasks and the cost of the crop loss related to the failure of meeting deadlines. It is common knowledge that the longer the execution of work lasts (e.g. crop harvesting), the more value it loses. The extremum of the cost and loss function is the minimum of the sum of expenses and the cost of losses which sets the optimal parameters, the mode of the MPA functioning and the work duration. The cost of inputs for the work performance within the objective function includes operating costs of the MPA for the scheduled amounts of work. With the increase of the duration of these works the expenses decrease, however, the cost of losses grows. The sum of the costs of inputs and losses has the extremum that sets the solution optimality. The cost of crop losses depends on the purchase price for the harvested crops and the crop losses intensity for each day of harvesting which we have already developed significant dependencies for. We have suggested the control flow charts for optimizing the MPA parameters and their functioning modes, we have evolved the notion of the objective function and the method of its calculation for different sets of assemblies. Through the example of the multipurpose complex assembly for stubble soil cultivation and simultaneous green manure dropping, we have analyzed the results of the task solution using the cost and loss function which is an effective method of the parameter optimization and the functioning modes of various machine assemblies and facilitates the choice of alternative options

Description
The aim of the article has been the study of deflection laws in tractor oversize low-pressure tires, intended for class 5 tractor propulsion. The research method was experimental. The "tire tester" and specially designed devices for determining the deflections of the inner and outer tube relative to the rim in the circumferential, radial and collateral directions have been used in it. A number of factors determine outcome indices of the wheel with pneumatic tyre. Among them the ability of the tire to deform so that at low - hysteresis losses in the rubber-cord casing and admissible stresses in it, based on resource, the largest area of contact with the supporting base has been created. This circumstance is of particular importance in the development of tractor tires of low pressure, deflection characteristics of which are poorly studied at present. Analysis of experimental studies showed the necessity of the feasibility of creating the tire with the cord orientation in its casing so that in the zone of perception of the vertical and longitudinal forces the cord threads would work in a mode close to the extension, but in the area of contact it would work in bending. These requirements will best meet the tire in which the cord threads are parallelly located in adjacent layers and directed at a predetermined angle in the direction of effect of the axial forces on the wheel in oncoming fibers
