ZIRCONIUM EFFECT ON THE STRUCTURE AND PROPERTIES OF TINI BASED ALLOY

abstract 1211607020 issue 121 pp. 475 – 483 30.09.2016 ru 464
We have performed a mechanical activation of TiNi powder; as a result, PN47T26TS27 powder after mechanical activation is flat discs ranging in size from 10 to 30 microns. We have developed a composition technology "steel - material with shape memory effect" by high-velocity oxygen-fuel spraying of mechanically activated powder based on TiNi. We have determined the optimal processing parameters to ensure a nanostructured surface layer. We have estimated the process parameters of highvelocity oxygen-fuel spraying. The basic parameters are: propane flow rate 60-85 l / min, that of oxygen 120-160 l / min, flow rate of powder and carrier gas (argon), distance and angle of deposition, and movement speed of the torch, the rotation speed of the coated workpieces. We have carried out macroand microanalysis of surface layers of Ti-Ni based alloy, obtained on proven technology. We have studied the effect of TiNi doping with a third component Zr. The simulation allows us to predict the possibility of using surface modification of products with SME material TiNiZr under certain conditions of temperature and to determine the desired composition of the coating, which provides a positive effect. We have made tests on steel 45 with a surface-modified layer TiNiZr under dry friction conditions, during which there is a significant increase in temperature, we have confirmed the effect of improving the wear resistance

ROLE AND IMPORTANCE OF URBANIZED AREAS' IMPERATIVE RESOURCES IN REGION NATURAL RESOURCE MANAGEMENT SYSTEM

abstract 1221608021 issue 122 pp. 292 – 303 31.10.2016 ru 464
The concept of the research is to justify the necessity to develop the regulatory declared dispositive basis in the system of social, ecological and economic management of the urbanized areas within the environmental system of the region, through the improvement of organizational-economic management mechanism of region natural resources and understanding the tools of this mechanism. The administrative-territorial formations are specific due to the necessity of being them considered in terms of socio-economic development as well as in the context of ecological and economic development of the territory that is connected with the necessity to ensure its sustainable socio-economic development. Ecological and economic management of cities and other urbanized areas are of the entire spectrum of public relations in the sphere of natural resources use and protection. The study of the city as the ecological and economic system is based on a number of conceptual problems in the applied management methods that ignore the general specificity of cities as the urban areas and sites of ecological - economic management, regardless of their level - single-industry towns, big cities or cities of regional importance. The ongoing soil degradation can affect the living conditions of future generations. The soil damage is caused mainly by industrial enterprises, being in various forms of ownership nowadays, including private. The improvement of legislation on soil protection from industrial pollution is a very relevant issue

ANALYTICAL TOOLS OF VECTOR RISK ASSESSMENT OF THE FINANCIAL MARKET

abstract 1221608035 issue 122 pp. 481 – 495 31.10.2016 ru 464
In rapidly changing conditions of the modern world, analysts and decision makers are in need to use new formal means of analysis and evaluation of alternatives problems. This work is dedicated to the development of such tools. The article presents a detailed analysis and technical and economic characteristics of the subject area - the financial market and its specific components - the value of a time series of gold, silver, palladium, platinum, and two kinds of exchange rates: EUR / RUB, USD / RUB. The authors have proposed a 5-criteria economic-mathematical model of the main components of the ranking of the financial market. The authors argue the impossibility of using a single integrated set of criteria for the replacement of the criteria or the use of criteria convolution procedures as the standard procedure of solving the problem of multi-criteria optimization. It demonstrates that such criteria as criteria for "risk" must be considered as an estimate of the degree of deviation from the expected value of the possible values of this criterion. The practical significance of the results is determined by the fact that the main points, conclusions, recommendations, models and methods can be used in order to improve the management and planning of development strategies of banking systems, trading platforms, as well as by developers of information and analytical systems to support management decisionmaking

MULTIVARIATE ANALYSIS OF THE SEPARATION PROCESS OF SUNFLOWER SEEDS IN MUS-1500AIR-SIEVE GRAIN CLEANING MACHINE

abstract 1301706082 issue 130 pp. 1122 – 1136 30.06.2017 ru 464
With the aim of improving the productivity and performance of the sunflower seed separation process in the air-sieve seed-cleaning machine called MVU-1500 its multivariate analysis was carried out. The main indicators of the seed heap separation process were determined according to the feeding of the seed heap onto the sieve of the lattice. The indicators are as follows: completeness of the j-th components screening, the j-th components content in the sieve path, the completeness of their discharge and their content in the discharge from the sieve tier. Having adopted the hypothesis of a possible increase in the efficiency of the separation process in the air-sieve grain cleaning machine, we analyzed the delivery patterns of seed heap components into the pneumatic channel with the aim of optimizing the process. For a more complete assessment of the process indicators under consideration, basic patterns of movement of various components in the sieve-tier lattice were estimated. It was taken into account that in modern designs of air-sieve grain cleaning machines seeds are fed into the pneumatic channel from the sieves. When the width of the lattice is equal to one, the density of the j-th component of the seed heap is constant along the length of each sieve in the stack of sieves and the separation coefficient is constant along the length of the sieve, the expression received estimates the average speed of movement in the first sieve-tier lattice in the steady process of separation. There was evaluated the statistical significance of differences of the j-th component average speed movement on the second sieve- lattice by Student's t-criterion, which showed that they belong to the same sample of random variables and do not have statistically significant differences. Therefore, we can obtain the following velocity values of the heap of sunflower seed movement in the sieve-tier lattice: fragments of stems velocity is 0.0518 m/s; milled seeds velocity is 0.0381 m/s; velocity of sunflower seeds less than 3.2 and 3.2-3.6 mm thick is 0.0835 m/s, velocity of sunflower seeds of 3.6-4.0 mm thick is 0.0453 m/s, that of more than 4.0 mm thick is 0.0410 m/s

PROSPECTS OF USING FRUIT AND VEGETABLES IN PUBLIC FEED

abstract 1281704089 issue 128 pp. 1268 – 1281 28.04.2017 ru 463
The main way to extend the shelf life of fruit and vegetable raw materials is low-temperature drying, characterized by high quality products, low energy consumption and affordable cost of finished products. More fully, a two-stage drying, the first stage of which is convective drying and the second stage - convective vacuum drying, meet such requirements. The article substantiates the prospects for the use of fruit and berry powders in public catering, using electro-physical effects that significantly reduce the loss of valuable components of the feedstock. The authors proposed a combination of conventional convective dewatering processes with vacuum microwave treatment, in order to achieve high quality indices of dried products. The aim of the work is to reduce energy consumption for drying and improve the quality of finished products. Among the objects of research, there are fruit and vegetable raw materials, designs of drying plants and technological modes of two-stage drying and devices providing it. The research subjects include the establishment of the properties of fruit and vegetable raw materials in the process of two-stage drying. The methods of research are based on the use of modern methods of analysis and instrumentation. On the way of widespread introduction of powders into the production of various food products, there is a problem of insufficient attention of producers to this type of product, low volumes of its production and monopoly of individual producers of powders

TECHNOLOGY OF POWDERED FOOD ADDITIVES

abstract 1311707056 issue 131 pp. 659 – 671 29.09.2017 ru 462
In recent years, the problem of deficiency of biologically active substances in a number of food products has arisen. This is due to a deterioration in the quality of seed and planting material and, accordingly, a decrease in the content of BAS in the cultivated fruit and vegetable raw materials. In this regard, processing companies are forced to fill the lack of vitamins and dyes with synthetic components. The aim of the research is to obtain concentrated food additives from domestic plant raw materials. To achieve this goal, the tasks of obtaining powders from fruits and berries are solved with maximum preservation of BAS of the raw material during drying. High-quality powders from fruits and berries are obtained by cryogenic technology, using liquid nitrogen at one or several stages of the process. As intermediate results of the research, the paper presents materials on the dispersion composition of cryopowders and the solubility of their various fractions in aqueous media. The technology of obtaining and using powdered food additives from fruits and berries, ground in liquid nitrogen, has been approved. The comparative characteristics of the composition cryopowders from apricot, sea-buckthorn, pumpkin, feijoa and persimmon are given. The results of the studies confirmed the expediency of using cryopowders from fruits and berries to enrich various food products

THE EFFECT OF "GORLINKA" MUSTARD PROTEIN-CONTAINING FEED CONCENTRATE ON NUTRIENT DIGESTIBILITY OF AGRICULTURAL POULTRY

abstract 1181604084 issue 118 pp. 1304 – 1318 29.04.2016 ru 461
This article presents the results of the impact of "Gorlinka" mustard protein-containing feed concentrate in the feeding of broiler chicken of the cross of "Cobb-500" on their performance and nutrient digestibility of the feed. The studies were conducted in the conditions of Krasnodonskaya Poultry farm in the Ilovlinskiy district of the Volgograd region. Full or partial replacement of sunflower meal with "Gorlinka" mustard proteincontaining feed concentrate in the feed mixture for the experimental broiler chickens contributes to the increase of the coefficients of digestibility of nutrients compared to the birds in the control group. The use of "Gorlinka" mustard protein-containing feed concentrate in the composition of feed for broiler chickens has contributed to higher coefficients of digestibility of nutrients: dry matter – 0.51-1,37%, organic matter – 0.6-1,99 %, crude protein by 0.8- 2,24 %, crude fiber – 0,34-1,65 %; crude fat – 0.94- 2,29%, compared to the birds in the control group. Nitrogen balance was positive in all groups; the use of nitrogen from the accepted experimental broiler chickens was higher in the experimental groups than in the control by 2.89-of 7.93 %. The use of nitrogen from digested nitrogen was higher in the experimental groups in comparison with the analogues from the control group by 2.65-of 7.97 %. The use of calcium and phosphorus by poultry was also higher in the experimental groups

METHODS OF DEFINITION OF COMPLEX MACHINE GRAINS’ AND SEEDS’ TRAUMATIZING

abstract 1201606026 issue 120 pp. 399 – 411 30.06.2016 ru 461
Damage of grain and seeds by machines makes essential negative impact on sowing qualities of seeds and processing properties of grain. While processing of grain a lot of various cars and actions differently injure weevils. To exclude traumatizing of grains in the course of mechanical preparation is not obviously possible, as working bodies of cars are a source of mechanical and thermomechanical damages. Besides, injured weevils on the physical-mechanical properties practically do not differ from whole, i.e. they do not possess signs for machine division. To reduce traumatizing of weevils is possible with the help of application of optimum technologies of machining, selection of the conforming technological modes, using as a part of actions of constructional stuffs with a low elastic modulus, perfection of their design data. For definition of injuring ability of various machines and actions through which takes place grain lots, have developed a procedure which allows with high degree of reliance to estimate complex traumatizing of weevils (namely, their outside integuments and intrinsic frames) machines and the actions which are a part of aggregates and complexes for machine preparation of grain and seeds. The developed procedure bases on a basis of the standard documents regulating test methods of agricultural machinery and together with it allows to consider connatural heterogeneity of the grain lots arriving for processing
