Energy complex of the country is a collection of
electrical installations high and low voltage, producing,
transforming, transporting, distributing and consuming
electricity. A huge web of networks and more than 700
generating plants with a total capacity of about 230 GW
[1]. Almost 90% of this potential is formed in a unified
technical complex of the Unified energy system (UES)
[2]. Now there is a deterioration of the performance of
the sector. In comparison with 90-mi years of XX
century, more than 1.5 times increased power losses in
the power grids. Significantly increased the proportion
of obsolete electrical and auxiliary equipment, and the
load on the network every day only increase. All speaks
of the necessity of both local and global modernization
of the electric power complex of the country and the
creation of a new concept of consumption management
and energy distribution in the network. In the
framework of the energy strategy of the Government of
the Russian Federation dated 13 November 2009 #
1715-R, to improve handling and ensure reliable
operation of electric power systems, wider introduction
of flexible transmission system (FACTS devices) and
improvement of systems of automatic emergency
protection and dispatching control [1]. The development
of electric power complex of the country should be in
the way of intelligent networks. This is possible through
the use of modern components that can make the
process of managing "intelligent". In foreign literature,
this term is called the Smart Grid
Sanitization of eggs is an essential way to fight bacteria, fungi and other microorganisms. Hatchability of eggs and the safety of day-old chicks are dependent on the quality of eggs processing. Leading scientists of our country have proved high efficacy of ozone application for processing of hatching eggs. To obtain a positive result by this method of sanitizing hatching eggs ozone, it is necessary to create a uniform concentration of ozone around the egg store volume. Decrease in ozone concentration from the set point may result in insufficient exposure to pathogens and because of this, may reduce hatchability. Significant excess of ozone concentration from the set point can kill the embryo. Because of mathematical modeling of electro eggs ozone treatment process, there was a mathematical model of the process of electroozonation of egg stores of poultry farms. This model takes into account decomposition of ozone on the surface of eggs and decomposition of ozone on the walls of an egg store. This mathematical model proves the desired control action at different initial data, such as: the required concentration of ozone in the egg store, the number of eggs, egg store geometric dimensions, the fan power, the design parameters of the discharge unit, the location of the ozone generator in the room
Nigeria has the largest oil sands and bitumen resources
in Africa and is one of the main leading countries in the
world from the point of view of its significant potential
heavy oil deposits. Research of geological and physicochemical
properties confirmed that the Nigerian bitumen
is an important energy source and an alternative source
of hydrocarbon feedstock for the petrochemical industry.
Nigeria imports black oil for the petrochemical industry
and its heavy oil can act in place of this black oil. In
addition, researchers have successfully established the
possibility of producing electrical energy from this
heavy oil. Tar sands and bitumen are able to help
improve the economy of Nigeria
In the article, we present the mathematical model of a
ventilation system with variable air flow along the
vertical axis of the reactor in the composting process. We
have solved the problem of the choice of the method of
supplying air to the bioreactor, reducing the temperature
of the substrate along the axis of the bioreactor. The
proposed method provides a reduction of temperature
and moisture content of the gas phase, which leads to a
change in the dynamics of the composting process. This
article was prepared in the framework of the scientific
project 16-48-230441 a(R) "Mathematical modeling of
the processes occurring in the automated installation for
year-round production of organic fertilizers in the
conditions of the Krasnodar region", financed by RFBR
and administration of the Krasnodar region
At the present time, due to the high demands on the
stability of the networks and information security, the
actual problem is the choice in the market of software
and hardware products, the protection of information
assets from a number of different threats that arise in
the corporate network. Despite the fact that the market
for hardware and software products offers a lot of
information security, it is difficult to leaders and
experts to find out how they differ from each other,
and what principles should guide their choice. In the
article, for solving the problem of the choice of
remedies, their purchase and installation on
workstations and enterprise network servers, it is
proposed to use a comprehensive methodology, based
on the methods of the game theory and the analysis of
hierarchies
The article has a research character which is expressed through the analysis of ways and means of mechanization for harvesting of solanaceous vegetables, and also endurance from works of scientists on the studied subject. Vegetable growing is an important branch of agricultural production. From a set of vegetable plants the increasing significance is attached to cultures which production contains physiologically active agents. Solanaceous vegetables belong to these cultures. In Russia, vegetables on an industrial basis are cultivated in the south of the country. Everywhere in Russia crops of vegetables are reduced. It is explained by high costs of production, especially on harvesting that at the general deficiency of manual skills leads to reduction of the areas, violation of technology of cultivation and harvesting and, respectively, to decrease in productivity. In conditions import substitution of foreign agricultural production and increase in the areas of landing of vegetable cultures in the Russian Federation for creation of a safety cushion food in the conditions of food embargo, undoubtedly, will be required the maximum mechanization of technological process of cleaning of vegetables. The most important results of types of designs of machines for vegetables and, problems of use of modern machines for cleaning of vegetable cultures are given. Our own design for harvesting solanaceous vegetables is offered

Chocolate products with reduced calories are
becoming increasingly popular among consumers and
producers. One method of producing chocolate with
low calorie content is some replacement with
alternative sucrose sugar substitutes. We have
investigated the effect of various bulk sweeteners
(maltitol, isomalt and erythritol) with different particle
size, divided into three intervals (106-53, 53-38, and
38-20 microns) on the rheological properties of molten
chocolate. It was found, that the model of the
Herschel-Bulkley is better than others, it describes the
real rheological properties of the chocolate mass. It is
established, that because of maltitol, it affects the
rheological properties of chocolate just as sucrose and
thus it may be a good alternative. The use of isomalt
causes higher plastic viscosity of the chocolate mass
and maltitol improves the fluidity of the chocolate
mass, significantly more than other bulk sweeteners.
Changing the particle size leads to a change in the
plastic viscosity and yield point. Differences in the
rheological properties of chocolate with different bulk
sugar substitutes have been caused by differences in
the volume fraction of solids and the distribution of
particle size. When replacing sucrose to improve the
rheological properties of the chocolate, we have to
select sweeteners with large particle size, but
sweeteners particle size should be small enough to
result in chocolate with good organoleptic properties
