A REVIEW OF THE CURRENT ELEMENT BASE WITHIN THE CONCEPT OF SMART GRIDS
DescriptionEnergy 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

06.00.00 Agricultural sciences
DescriptionAn experiment was conducted to examine the effect of fatty acid concentrate (FAC), as a new source of energy and carnitine on performance, physiological condition and meat quality of broiler chickens. In experiment there were four groups of 80 chickens of cross Hubbard each (males: females=40:40) in age period 0-41 days. 1 group (control) received in during the periods 0-14, 15-28 and 29-41days, sunflower oil (SO) respectively 5.34%, 5.50%, and 6.10%, group 2 received the same amounts of FAC instead SO, 3 group - mixture SO:FAC (50:50), 4 group -FAC + 0,25% carnitine. Final body weight: 1 group = 2574±29 g, 2 group FAC= 2553±27 g 3 group SO + FAC = 2531±34 g., 4 group FAC+0,25 carnitine = 2520±34 g. Feed conversion, digestibility of nutrients, blood hematology and biochemistry, the condition of organs, meat quality and cutting of carcass of chickens on FAC had no any differences from the same signs in chicks on SO. Carnitine had a positive effect on chicken growth only in the period 0-14 and less 15-28 days; in the period 29-41 days daily gain was below, than that in 1-3 groups. Canitine reduced the content of liver fat. Outcome: FAC is a satisfactory source of energy, comparable with vegetable oils. The price of FAC is 30% lower in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of vegetable oils will be of great economic importance

Description
Decision-making requires a thorough analysis of the external environment in which the economic system operates. Anti-Russian economic sanctions is significantly destabilized external environment that has complicated the task of making decisions on management of the enterprise. This study analyzes the problem of decision making under conditions of the uncertainty caused by the anti-Russian sanctions, the conclusion about the limited decision-making methods based on game theory. The most effective are management practices supported by information systems. The article analyzes the current information technology of managing a company made by different developers who have already installed their software products on objects, which are strategic for the Russian economy. In terms of economic sanctions, such a situation creates a threat to the economic security of the country. Based on domestic developments, it is proposed to construct an information model of the enterprise, which will reduce the risks and increase the quality of managerial decisions. The work presents a structural scheme of the information model and defines its objectives and characteristics

TO THE QUESTION ABOUT CONCEPTUAL BASES OF PATRIOTIC EDUCATION OF CADETS IN THE CITY-HERO
DescriptionUnder contemporary conditions in Russia, patriotism took again its rightful place in the treasury of the education of the younger generation. Having gone through many years of testing, attempts to oblivion, libel and slander, patriotism has been returned to pedagogical arsenal by efforts of the best Russian people. However, the atmosphere of decelerations and partization, nationalist sentiment increasing, immoral behavior of young people are persisting. Percentage of maritime university’s cadets has a declining interest in the patriotism subject. Thus, 78% of cadets reported that they did not read fiction on patriotic themes; 53% do not watch military-patriotic films; 29% are not interested in the history of his native city. The data indicates a lack of using educational potential and the special flavor of the hero cities, where they are located, their rich and glorious history, and established for ages tradition of serving the motherland. Now for this reason, the administration, the teaching staff of maritime universities have not only an intention of qualitive patriotic education, but also to search for new forms and methods, to use a regional and municipal component, to develop cadet’s attention, interest and desire to participate in patriotic events and patriotic activities. The working on cadet’s patriotic education of maritime university can become one of the most modern and innovative directions. This work shall consider conditions, historical and educational potential of the city, where an educational institution is located, studying of its glorious history, combat and labor traditions, as the cognitive basis for the patriotism formation of the highest school’s students

Description
We have performed an experimental study of the evaporation process at a temperature of 105 ° C for the egg white model solution in distilled water to evaluate the ratio of the heat transfer coefficient from air to water ratio mass transfer to the water surface into the air by evaporation from the free surface in a forced convection. Evaporation of the solution was carried out in a Memmert oven of class Basic (Germany) equipped with forced air circulation, the control panel with a display and a temperature control device. To determine the surface temperature at which the main evaporation of water from the process solution, the experiment conducted under the same conditions by measuring the average temperature of the layer of water sample, placed in a Petri dish in an oven with a sensor - DMM Mastech M838 series. It is found that the coefficient of heat transfer from air to water almost a thousand times greater than the coefficient mass transfer from the water surface into the air

PARTICLE COLLISIONS IN THE RICCI FLOW
01.00.00 Physical-mathematical sciences
DescriptionIn this work, we investigate the problem of collisions of particles linked to the singularities of the gravitational field in the Ricci flow. A system of non-linear parabolic equations describing the evolution of the axially symmetric metrics proposed. We consider the metric having axial symmetry and comprising two singularities simulating particles of finite mass. There was numerically investigated the change of the metric in the collision of particles. Two formulations of the problem have been considered, one of which scatter particles after the collision, and the other as a result of the merger of two particles, a new stable static system, which can be interpreted as a new particle. The initial and boundary conditions using the exact solution of the static problem, so the collision persist particularly metrics caused by the presence of particles. In numerical experiments determined that the collision of the particles in the Ricci flow leads to the formation of gravitational waves, similar in structure to the waves, registered in the LIGO experiment. Consequently, we can assume that the observed gravity waves caused mainly by transients associated with the change in the metric system. A model describing the emission of gravitational waves in the collision of particles in the Ricci flow proposed. The influence of the parameters of the problem - the speed and mass of the particles, on the amplitude and intensity of the emission of gravitational waves was numerically simulated

SOME ASPECTS OF REDUCING FRUIT DAMAGE DURING HARVESTING AND TRANSPORT OPERATIONS
DescriptionFruit harvesting is the final and decisive operation in the general work plan for growing fruit, which largely determines the qualitative and quantitative indicators of production and economy of industry in general. Increasing productivity by improving the safety of fruits and vegetables is a priority and not an easy task. For example, the use of cleaning technologies with the use of machinery for harvesting of apples by shaking can significantly reduce the time of gathering fruit compared to hand harvesting. This technology may be applicable, if the fruit is grown for the manufacture of juices, jams, etc. Currently, in several European countries and in the USA, they widely use fruit harvesting platforms and machines. The leader in the production of fruit harvesting platforms is Italy. To reduce the damage to fruit in agriculture, the analysis of the traumatic factors is of great importance, with the analysis of available machines and their subsequent modernization with the aim of improving the reliability and quality of harvesting and transport process, taking into account of the algorithm for solving these problems, the creation of new varieties of fruits and vegetables suitable for machine processing, strict compliance with deadlines and agronomic requirements for the performed technological operations, taking into account the savings of energy and resources when using mobile technology. In addition to the modernization of the machines for efficient operation, it is necessary to improve also the scheme of planting of gardens and methods of cultivation, transfer horticulture to intensive way of development
