The carried out analysis studies the influence of
various factors on the preservation of
agricultural products and shows that it is largely
determined by design features of machinery and
technological methods of use. The efficiency of
agricultural and mobile trailer machines has
been forming by service and storage. Low
quality of work associated with the storage of
agricultural machines is conditioned by the fact
that the lack of financial capacity of rural
producers on acquisitions of modern equipment
and materials for carrying out the preparation of
for long storage, and also the construction of
modern agricultural machinery storage sites. If
a car can be fully or partially protected from the
solar radiation, rain and snow, simply by
removing it in the room, under a canopy or
covered with a protective cover, by the
formation of condensation on the surface of the
machine units and parts these ways to protect
do not work. Enhancing of preservation of
agricultural machinery is possible when
protecting the vehicles from atmospheric
precipitation in the form of snow and rain,
influence of solar radiation, and also due to the
change heat exchange processes of the machine with the environment that prevents the
formation of moisture condensate on its surface,
ie. we have to create conditions when cooling
rate at which the surface of the machine would
be equal to or less the rate of cooling air. This is
possible through the use of a special design,
which would prevent the intense heat radiation
of the machine into the environment, ie, would
reflect heat rays using its surface and return
them to its surface and thus fulfill the role of the
heat shield
Nowadays in Russia, there is a problem of utilization
of vehicles. A system of recycling of agricultural machinery
in Russia is absent. In the article we present
an organizational-technological complex of works for
utilization of agricultural machinery
The modern level of development of the industry requires
creation of more difficult and high-precision
systems of an electric actuator allowing executing precisely
and correctly the given technological processes.
As these devices, we may consider hybrid or cascade
systems of an electric actuator. However, for creation
of such devices we require new design approaches, or
specification and improving of the existing theories and
methods of design of classical systems. The main difficulty
in calculation consists in determination of parameters
of electromagnetic system. In this article, new
approach is given in finding of electromagnetic parameters
of components of an asynchronous controlled
cascade electric actuator taking into account real geometry.
This approach was formed during creation of
the program complex, which is a part of a system of
automatic design
The article noted that the aggravation of the problem of
economic sustainability of agricultural organizations in
the modern market economy, caused by the influence of
the complex as a deterrent, and potentially contributing
to internal and external factors, showing up at all stages
of the reproductive process. Investigation of this
problem has allowed allocating and justifying the most
important factors, classified in the context of
organizational, economic, innovation and investment,
financial and social components, affecting the process
of ensuring the economic sustainability of agricultural
organizations, taking into account the specific
conditions of their operation. Among the constraints, we
highlighted the high cost of borrowing, the fiscal tax
policy, price disparity, lack of working capital, high
financial risks and depreciation of fixed assets, low
production efficiency, aging staff, lack of highly
qualified personnel, and others. Among the factors
conducive to economic stability, we defined such
factors as loans, incentives, insurance, government
support, the intensification of innovation, use of new
resource-saving technologies, modernization and
reconstruction of production, increasing the
responsibility of the business, improving human
resources and others. The proposed classification by the
nature of influence on the object of control in the
context of structural and functional components enables
the development of mechanisms and tools to increase
agricultural organizations adaptation to the changing
environment. The author concludes that by taking into
account all the factors and the formation of an effective
management system based on agroeconomically
harmonious coordination of market mechanisms and
government regulation, it is really possible to achieve
economic growth that will create the conditions for balanced, sustainable and socially-oriented economic
development
This article analyzes the best practices of choosing the

For the first time results of researches on potential productivity and environmental role of hayfields in the Indigirka river basin (Momskiy district) are presented. Researches proved that feeding meadow plants in conditions of the Indigirka river basin, depending on the type of vegetation, location and features of root systems, provide maximum crop productivity – up to 18,5 dt/ha of hay with productivity of 1 ha for harvesting exchange energy up to 16,1 gigajoule, fodder units 1130 and crude protein up to 209 kg maximal underground mass accumulation of meadow plants was formatted in the region of Indigirka and Khonuu – mixed and squirreltail barley (hordeum jubatum) hayfield up to 193,6 dt/ha, dry matter and carex duriuscula and squirreltail barley hayfield up to 252,2 dt/ha with the majority of roots in layer 0-10 cm. up to 76-88%. Field of Khonuu, with mixed and squirreltail barley hayfield, contained underground nitrogen – up to 33 kg/ha and labile phosphorus – up to 71 kg/ha. Increased accumulation of labile phosphorus root mass provides enhancement of cold resistance ability in conditions of the subarctic zones of Yakutia
Antibacterial chemotherapeutic drugs, which include antibiotics and synthetic antimicrobial agents, are widely used in veterinary medicine for the prevention and treatment of diseases caused by microorganisms. Antibacterial agents can be classified by type of action and chemical structure. It is also known that when several drugs are used in combination with each other, they interact within the body with each other, which can lead to strengthening or weakening of their action. For these reasons, it is of scientific and practical interest to develop a classification of antibiotics by their characteristics and principle of action (task 1), as well as by mutual compatibility (task 2). The article solves these problems using a new method of agglomerative cognitive clustering, implemented in automated system-cognitive analysis (ASK-analysis). This method of clustering has a number of advantages over the known traditional methods of clustering. These advantages allow us to obtain clustering results that are understandable to specialists and amenable to meaningful interpretation, which are well consistent with the experts ' assessments, their experience and intuitive expectations, which is often a problem for classical clustering methods. The article provides detailed numerical examples of solving two problems. The universal automated system called "Eidos", which is a tool of ASK-analysis, is in full open access on the author's website: http://lc.kubagro.ru/aidos/_Aidos-X.htm. Numerical examples of solving veterinary problems with the use of artificial intelligence technologies are placed as cloud Eidos-applications and are available to everyone
Trends in economic growth and the active inclusion of
Russia in the global dynamic processes require a sharp
increase of its competitiveness on the world stage, the
growth of production and consumption culture, which
in its turn sets the task of raising the quality and
education efficiency to a new level, corresponding to
the scale of problems. In the article the ways of
improving the education management system, allowing
not only to identify new approaches, but also to look at
the problems of the industry in a completely different
way are analyzed. The article presented by the authors
is based on the modern conception of education
potential that should be fully used for consolidation of
the society, the preservation of a single socio-cultural
space of the country, overcoming ethnic tensions and
social conflicts on the basis of the priority of individual
rights and equality of national cultures and different
faiths, limit of social inequality. The authors consider
education as one of the largest areas of the world
economy and one of the fastest growing sectors
The article presents the main directions of the
application of the scree plot method in solving
metrological problems in the social and humanitarian
fields of knowledge (economics, pedagogy, sociology,
including sciencemetry). It is known that statistical
measurements in socio-economic systems are
inextricably linked with the processing of primary
homogeneous monitoring information. It is also known
that empirical averaging (computation of the empirical
mean), as the dominant method of mathematical
statistics, is becoming a thing of the past, due to moral
aging, inconsistency with modern requirements
(primarily to measurement results in socio-economic
systems); In science meteorology, this method was
replaced by the scree plot method (the Hirsch index
and other scientometric indicators are estimated on the
basis of this method). Despite its enormous potential,
the scree plot method, as an alternative to traditional
methods of mathematical statistics, is very poorly used
in the social and humanitarian fields of knowledge.
The authors of this article have shown that this method
can be successfully applied in solving various
metrological tasks, not only in science (sciencemetry is
a branch of science), but also in economics, pedagogy
and sociology. In addition, the authors show
modifications of the scree plot method, using the
example of measuring (measuring) indicators in the
economy, sociology and pedagogy; The relationship
between the scree plot method and the theory of latent
variables (qualimetry) and database technology is
grounded. The authors also substantiate that the scree
plot method - the basis for the formation of monitoring
indicators that adequately reflect the performance of
socio-economic systems. The practical significance of
the results of this study is that they can be used in
socio-economic and psychological-pedagogical
monitoring systems (according to modern views,
monitoring is an information management
mechanism). Methodological basis of the research:
system, sociological, competence, probabilitystatistical
and qualimetric approaches (leading
methodological basis is the probabilistic-statistical
approach). Research methods: modeling; Methods of
graph theory, sets and relations; Systemic-cognitive
analysis; Methods of qualimetry (the theory of latent
variables); Methods of mathematical statistics
This work is devoted to a new method for designing
large-scale structures of transport networks. The
model of a large-scale transport network is built on
prefractal graphs. The model of a large-scale transport
network is based on the principle of hierarchical
organization of territories. A prefractal graph is a
finite analogue of a fractal graph combining the
properties of a fractal and a graph. Some problems of
discrete optimization on prefractal graphs become
polynomially solvable under certain conditions.
Reducing the complexity of extreme problems on
prefractal graphs is due to the fact that on these
graphs for some problems, along with the selfsimilarity
property, the property of heredity appears.
Using this property, it is possible to construct parallel
algorithms for problems on prefractal graphs, the
complexity of which is orders of magnitude lower
than for known successive algorithms
