PERFECTION OF CLEARING OF WATERS FROM PETROLEUM TECHNOLOGY
DescriptionNowadays there are sorbents, both natural, and modified, which allow to clear waters from variety of pollutants simultaneously, for example from ions of heavy metals and petroleum. We have received a new modified sorbent with use of a sol-method. The given sorbent represents beads in common besieged magnesium hydroxide and aluminum having layered structure. For the characteristic of the structure of the researched systems we have carried out an X-ray analysis. Studying the mechanism of interaction of the sorbent with ions of heavy metals was carried out with the use of the research of chemical structure of the sorbent and the condition of adsorbed ions by methods of IR spectroscopy and X-ray analysis. The conclusion was made, that modified inorganic sorbent on a basis of magnesium hydroxide and aluminum has a number of distinctive features and advantages comparing to other filtering materials

Description
The work is scientific and practical in nature, same as the discussed process of optimization of power losses in power networks based on the use of the transportation problem, namely the rules of the minimum element of the transport matrix, which is a valid solution. The mechanism of the improvement of the obtained feasible solutions to the tasks focuses on using the potential method, assigning each row and column of the matrix their corresponding potential. Using a basic variable and manipulating the elements of the transport matrix according to a specific algorithm, we implement the construction of a new support plan. Based on the plan and its acyclic, we build two cycles and determine the values of the estimates between direct and indirect transportation costs per unit of output. The resulting algorithm makes it easy to program all computational operations and quickly obtain the result of the optimization of power losses in the design of the electricity network, thereby reducing the economic and technological costs. As a result of joint use of transportation problems and potential method, we could find the optimal solution based on improved solutions more efficiently, and a scheme of optimal electric network. As consumers, in practice, there may be urban and agricultural, industrial enterprises, regional and district subordination, including industrial, agricultural and individual customers

STUDYING CONFORMATIONAL REARRANGEMENTS OF PROTEIN WHEN DRYING
DescriptionThe article gives a review and the experimental data on the nutritional value of eggs protein comprising protein, carbohydrates, minerals and amino acids. Metabolism, the structure and function of each cell, as well as external and internal protective functions are defined by proteins. We consider the study of functions of trace elements found in significant numbers in the eggs, which contribute to health: vitamin D, vitamin B12, choline, folic acid, selenium, lutein and zeaxanthin. The high content of egg protein contributes to greater satiety, weight loss and eye health. We present experimental data on the amino acid composition of the protein and experiments of drying a cooked egg white, placed in a Petri dish. After 10 minutes of drying, the weight of the protein did not change and amounted to 0.1 g, which is 16% of the weight of the original white protein. The photo shows that the protein is lost during drying white and became transparent, and protein grains look like "melted" and partially connected with each other. The data obtained can be used for understanding the operation of the biological process of protein in vivo

DETERMINATION OF METALS CONSISTS IN REGUL, THE RAW RICE SORT
DescriptionThe content of metals in raw rice is determined. Inversion voltammetry (IVA) was carried out in an accredited laboratory on the "Ta-Lab" device of the company "Tom-Analit" LLC according to the approved method of ERD F 16.1: 2: 2.2: 2.3.46-06. Silicon dioxide is determined according to ERD F 16.1: 2: 2.2: 3.65-10 and humidity according to GOST 5180-2015. Preparation for the IVA is illustrated. Voltammograms of the potential difference of the chloride-silver reference electrode are compared with the current strength of the indicator mercury-film electrode of electrochemical cells. It has been established that the main metals of the raw rice called Regul grown in the Krasnodar region are: copper 1.6 ± 0.4 mg/kg, plumbum 1.4 ± 0.4 mg/kg, zinc 1.9 ± 0.5 mg/kg, iron 95 mg/kg, manganese 5.2 ± 1.3 mg/kg and silicon dioxide 6.5 mg/kg. The presence of iron is associated with the wear of gravity. The content of zinc, manganese and silicon dioxide corresponds to this type of grain. The presence of copper and lead is associated with the absorption of heavy metals from the soil

FREE-COOLING IN SEASONAL COLD ACCUMULATOR
DescriptionOne of the traditional ways of reducing energy consumption is the utilization of seasonal cold accumulator which takes advantage of the geographical location of a country that allows, during the winter season, that is, November, December, January, February, March accumulates cold as a result of lower ambient temperature in these months. Significant amount of electricity is reduced as well as reduced operating refrigerant, which is harmful to the environment. The article presents determination of the size of cold storage with charging devices as chiller and dry-cooler. The approximate costs of the device operation as well as the time of assembly of these components have been obtained. The design of a seasonal cold accumulator is a system that brings a number of economic and ecological advantages. The seasonal tank design is a prototype of the chiller; it is smaller than the actual tank that will be selected for the highest hourly energy demand. This means that the actual device should be several times larger than the device that was used in the project. By selecting a small chiller and fewer refrigerants (mainly chlorofluorocarbons) called R- 410A, the environment would be saved from contaminants which are hazardous

REAL AND VIRTUAL TEXTS IN A PROCESS OF TEACHIG FOREIGN STUDENTS (ON A BASIS OF RUSSIAN LANGUAGE)
10.00.00 Philological sciences
DescriptionThe article deals with different approaches how to interfere texts analysis in the program of teaching foreigners (on the basis of the Russian language). According to our research, for beginners it is more reasonably to use and analyze real texts, as far as these texts are close to life, have simple vocabulary and grammar. For the virtual texts the situation is the opposite. The main aim of the author is to please the reader, that is why the author uses a lot of tropes, metaphors, figures and very complex grammar to show the beauty of his language. For foreign students this may be a problem at the beginning, because they are not good in the language and it is very hard to understand. The analysis of the virtual texts is better to do on the base or advanced level

DEVELOPMENT OF FOOD PRODUCTS FOR RUGBY ATHLETES
DescriptionIn 2016, the game of rugby for the first time included in the program Olympic Games with a team of seven players. It is well known that achieving significant results in speed-strength sports, which include rugby, is impossible without a high physical, psychological and neuro-psychic loads, which are always subject to the athletes during training and competition. Nutrition should occupy an important place in the training of highly-skilled athletes, rugby players. It is known that the decisive factor in Rugby is an adequate supply of carbohydrates (glycogen, muscle and liver, blood glucose). Prolonged exercise leads to a depletion of glycogen, thus may slow down growth meristematic tissue and worsen the body's recovery after the event. In view of the fact that rugby belongs to the speed-strength sports mind, there are additional requirements for carbohydrates with different chain lengths, easily digestible proteins and basic micronutrients. In the daily diet can not provide the athlete a sufficient amount of protein and carbohydrates, as well as the need to sustain their relationship. To solve this problem, we have to include specialized protein-carbohydrate foods that have high nutritional and biological value in the diet of athletes, rugby players, which are able to quickly restore glycogen stores and protein to prevent loss of muscle when intensive training. Thus, the development and practical implementation of specialized technology of the protein-carbohydrate foods for athletes, rugby players is actual and up-to-date
