THE FUNCTIONAL INTERRELATIONS AND INTERFERENCES DEFINING STABILITY AND EFFICIENCY OF REPRODUCTION PROCESSES IN INDUSTRIAL WINE GROWING

abstract 1221608046 issue 122 pp. 669 – 680 31.10.2016 ru 349
The article defines types of functional stability of reproduction processes. We have proved the need of identification of interrelations between factorial and productive signs, their nature and extent of influence by types of stability (eco-economic, technological-economic, financial and economic) and efficiency (eco-economic, technological, economic). The generalized characteristic of the models and methods used for detection of dependences of the functional interrelations and interferences determining functional stability and efficiency by stages of reproduction process is given. Eco-economic stability of system is provided when the balanced coherence of interrelations and interferences in the optimum range is observed: "ability of self-reproduction – anthropogenous loading", or "an initial (standard) state – resource expenses – compensations", on each element of reproduction processes. Technological and economic stability is formed by an optimality of interrelations "process efficiency – productional effectiveness"; "productional effectiveness – economic efficiency" which allow to determine parameters of rational sufficiency of realization of productional potential of plantings and size of expenses of the economic resources providing the set reproduction level. Level of realization of reproduction potential of structural elements of an agroecosystem in comparability to the level of technogenic loading is determined by each element of an agroecosystem by the empirical and statistical method allowing to give a statistical assessment to the importance of the revealed dependences and to verify the received results. The regression models characterizing interferences of the factors influencing the level of eco-economic, technological - economic and financial and economic stability of reproduction processes are constructed

OPTIMIZING THE SHAPE OF A CENTRIFUGE ROTOR

abstract 1321708082 issue 132 pp. 1056 – 1065 31.10.2017 ru 349
The use of regenerated oils reduces the consumption of fresh oils for refilling, while oil filtration during the operation lengthens their service life and reduces the consumption of fresh oils for replacement. To restore waste oils, a variety of technological operations are used, based on physical, physicochemical and chemical processes. They are aimed at treating the oil in order to remove aging products and pollution from it. The studies have shown that the most effective means of recovering the quality of waste oils are small-size regeneration plants. The main difficulty in creating small-sized regeneration plants is the selection of a sufficiently effective, environmentally safe and economically justified method for the regeneration of waste oils, as well as its hardware design. This work is aimed at creating an efficient centrifugal cleaner

We have conducted experimental and analytical studies showing the relationship of constant and pulse forms of current sedimentation on the physicochemical properties of chrome coatings: adhesion strength to the substrate, residual stress, fatigue life, elongation and contraction, yield stress, and endurance. We have shown the methods and modes of use of dilute electrolyte of chromium plating with organic additives, is capable of applying a chrome coating on parts of agricultural machines, surpassing the properties of the coatings obtained from electrolytes that are recommended by the GOST standards. The proposed hardening chemical-thermal coating technology for chromium in the manufacture and repairing of worn parts of agricultural machinery (rods of hydraulic cylinders, journals of crankshafts, spools, parts, gearboxes and transmissions, etc.), identifies the consumption of additives modifiers, proposed methods for their determination, confirmed by patents for inventions. The proposed technology of worn-out surfaces of parts of agricultural machinery of layer-block structure of the chromium coatings with improved properties. The influence of modifying organic additives on the structure of the intermediate surface film of colloidal trivalent chromium compounds, which in combination with the parameters of the bipolar pulse current allows you to specifically adjust the physical and mechanical properties of crystals of the deposited chromium layer with a grid of cracks, and without them for the required operating conditions of dry friction or oil environments, which increases the durability of the parts during use. The increase in yield, at the current 6-8 %, to 4 times reduces the degree of hydrogenation of the restored details, up to 3 times reduces internal friction, roughness, improves the limits of strength, toughness, elongation and contraction, increases corrosion resistance up to 3 times, obtained chromium coatings

IMPACT OF WAYS OF INCORPORATING RICE STRAW INTO THE SOIL ON RICE YIELD

abstract 1341710051 issue 134 pp. 650 – 660 29.12.2017 ru 349
In the conditions of the two-factor field experiment, the influence of four methods of incorporating straw in the soil on the rice yield was studied: plowing, one-, two- and three-time discs and three ways of "processing" the straw: embedding in the soil of the chopped straw in its pure form, together with compensating nitrogen fertilizer and inoculated stubble biodestructor Stemix ® Niva. It is shown that the lowest yield is formed when straw is plowed, while surface tillage of soil by one-, two- and three-fold discs significantly increases the grain yield in comparison with the plow by 2.4, 4.2 and 5.2 c / ha, respectively. Taking into account that the double disking provided an almost twice increase in the yield of the crop and the absence of statistically significant differences with the triple disking; it is this method of incorporating the straw that should be considered the most expedient. The introduction of a compensating nitrogen fertilizer ensured a reliable increase in yield by 5.1 and 3.7 centners per hectare in comparison with the variants with the introduction of straw in pure form and treatment with biopreparation. Calculation of the share of the influence of the factors studied on the rice yield showed that the method for embedding straw provides 29.9% of the variability of the trait under study, the method of straw treatment is 36.7%, and the residual dispersion accounts for 33.4%. Incorporation of chopped rice straw in the soil together with compensating nitrogen fertilizer in the amount of 1% of the mass of straw, by double discing, ensured the receipt of a conventionally net income of 6940 rubles / ha, the rate of return - 70.4% and the cost recovery - 1.7 rubles / rub

ENVIRONMENTAL AND ECONOMIC ASPECTS OF INDUSTRIAL LIVESTOCK

abstract 1251701030 issue 125 pp. 443 – 463 31.01.2017 ru 348
One of the main criteria of efficiency technologies in livestock production is the level of the negative impact on the environment per unit of time, or volume of production. Intensification and specialization can significantly improve efficiency, but at the same time can increases the impact on agro-ecosystem. An important condition for the preservation of ecosystems is to find ways of using animal waste as a raw resource. The ecological balance can ensure the production of meat and dairy products for industrial technology in family farms of 50-200 cows and up to 10 thousand pigs. Economically advantageous to carry out the raw manure to a distance of no more than 10-15 km, which is achieved with a small population, when fully formed wastes are used to improve soil fertility. For large mega-complexes advisable to equip their facilities for the production of biogas and the use of covered manure storage. In its turn, to prevent infection of livestock production, bentonite clay should be used as sorbents. This technology content of the stomach-governmental and poultry should be humane with respect to them, environmentally safe for the ecosystem, cost-effective and competitiveness for producers, safe for consumer

CONTROLLING OF CONSUMER PRICES DYNAMICS AND LIVING WAGE

abstract 1261702030 issue 126 pp. 403 – 421 28.02.2017 ru 348
In accordance with the Presidential Decree of 21 August 2012 № 1199 one of the 11 integrated indicators of the activity of executive authorities is the measure "real disposable income of the population". For its calculation it is necessary to measure the level of consumer prices. The article presents the minimum consumer basket of physiologically essential food products, designed in 1993 by the Institute of High Statistical Technologies and Econometrics (IHSTE) based on the initial data of the Institute of Nutrition of the Russian Academy of Medical Sciences, and the results of measuring the cost of the consumer basket IHSTE and inflation index in 24 years (1993 - 2017). We discuss the application of the developed tools in Controlling of the level of consumer prices and living wage. According to M. Orshansky, living wage can be estimated by multiplying the cost of the minimum food basket by a factor which is equal to the quotient of all costs to the costs of food costs for a poor family. This work is aimed at the elimination of the monopoly of Rosstat in the calculation of indices of inflation, the living wage and the real disposable income of the population. The methods of the measurement and the use of inflation constitute an important part of training courses in econometrics, which are taught in the context of the scientific-educational complex "Engineering Business and Management" of the Baumann Moscow State Technical University. Nobel Laureate in Economics Vasiliy Leontiev thought that only 1% of economists analyze the newly collected data, 30% use the data contained in the publications of predecessors, and the rest did not turn in their arguments to the real world. This work belongs to the 1% of publications (which analyzes the newly collected data), about which Vasiliy Leontiev wrote

POWER SUPPLY UNITS OF OZONE GENERATORS USED IN AGRICULTURAL MANUFACTURING

abstract 1301706008 issue 130 pp. 128 – 138 30.06.2017 ru 348
Numerous studies confirming the effectiveness of the use of the ozone-air mixture in various fields of agricultural production lead to an increase in demand for devices that generate ozone. With the increase in demand, the requirements for these devices also increase. Requirements from customers can be combined in the following series: mobility, ease of operation, ability to smoothly control performance. The solution of these tasks is an important scientific and technical task. This article describes possible options for power supplies for ozone generators, and offers a power supply circuit with the ability to adjust the frequency, the duty cycle and the amplitude of the signal arriving at the discharge gap of the ozonizer. Using this scheme will reduce the mass-size indicators of the ozonizer, thereby increasing its mobility, in addition, it will be possible to accurately regulate its performance and improve efficiency. If necessary, with the help of the proposed scheme, it is possible to introduce the ozone generator into the electric resonance mode, which will allow obtaining the maximum productivity of the ozonator. Thus, the ozonizer, equipped with the proposed power scheme, can be used in various technological processes of the same enterprise
