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
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
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
A computing experiment with software

variability within classes and an affinity of the
classes. An accuracy of the operating mode was
assessed. The article also shows possibilities of
decreasing of video frame processing in CVS
operating mode through an optimization of
sequential computation and organization of parallel
computation
27 introduced variety samples of rice from 8 countries
were studied by the complex of biological,
morphological, agronomic traits to select the most
valuable genotypes for including them into breeding
programs on development of cold tolerant rice
varieties. It was found that the studied introduced
varietal samples were characterized by variation in
duration which varied from 120 to 182 days. Variety
samples from Bhutan ATTEY, PARO DUMBJA
(White) had shown response to photoperiod and the
panicles didn’t appear in conditions of Krasnodar
region. During the study there were selected high
productive forms Obongbueo and Tinbubueo from S.
Korea with grain weight 81.67 g / vessel and 74.43 g /
vessel, respectively. According to results of research
there were selected five cold tolerant samples Tong

those of standard check variety Kuban 3, as well as
those of samples with increased resistance IR83222-
F8-14 and IR83222-F8-156 (Philippines), PARO
DUMBJA (White) and THIMPHU DUMBJA
(Bhutan). As a result of research there were selected
three introduced rice variety samples Tong Jing 29
(China), Tinbubueo (S. Korea) and SR 30084-F8-156
(Philippines) which by duration, morphotype and
agronomic traits are considered as candidates for
further hybridization and breeding as sources of useful
traits and properties
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
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
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
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
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
