The object of the study was the sweet pomace of red varieties of grapes grown in village Taman Temryuk district of the Krasnodar region. By grinding in a laboratory mill and drying in a drying oven at a temperature of not above 60 ºC, a powder is obtained from the mash. Its quantitative chemical analysis has been carried out. The mobile forms of metals and the total content of metals are determined. The content of mercury, lead, arsenic does not exceed the permissible levels of the maximum content of toxic elements in flour confectionery products. The influence of powder from grape pomace on the quality of the finished product and on the properties of the pastry test was studied, as the control sample was chosen the recipe for the sugar cookies "Carrot". A part of the flour was replaced with grape-dried powder in amounts of 1 %, 2 %, 5 % of the mass of wheat flour of the highest grade in the test. The recipe of sugar cookies with the addition of powder from grape pomace and without, calculated on 200 g of finished product, and organoleptic parameters of the finished biscuit is given. It is established that the use of grape-dried powder allows to increase the mass fraction of dry substances and to reduce the mass fraction of sugar in confectionery products, as well as to enrich them with mineral substances, microelements, which are necessary for normal functioning of the organism. Biscuits with the addition of powder from grape pomace are a good source of ballast substances reducing caloric content, which contributes to the removal of harmful substances from the body: cholesterol, heavy metal salts, etc

The 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

The article describes the sources of noise Yeisk thermal power plant (TPP) in excess of the permissible sound pressure levels in homes on the street. Gorky, 25. Eisk TPP is located near the residential area, where the permissible noise level standards adopted much more stringent than in the power plants. Prolonged exposure to noise leads to human disease noise disease. The scheme of movement of exhaust gases from the thermal power plant generating units Yeisk. Analysis of measurements of noise characteristics of main and auxiliary equipment showed that one of the main sources are sectioned estuaries double-barrel pipe height of 27 m and slices estuaries pipes emergency explosive valves flues installed on the roof at a height of 17 m. The previous Noise reduction nozzles that emit noise uniformly in all directions are replaced by advanced, whose index changed direction estuaries sections double-barrel tubes. This will change the level of radiated noise in residential development. If you change the angle of orientation of 135°-180°, the noise level in residential construction decreased by 7-10 dB. Shows a photograph of thermal power plants, residential buildings, the old and improved silencers

Production ecological control is an integral part of the national environmental monitoring system. The article describes the results of production ecological control of impurity of groundwater drawn from wells in the territory of the Tuapse refinery and presents a situational plan of wells layout in the Tuapse refinery. Analysis of groundwater was represented from 2012 to 2016 with their content (mg/l) of oil, phenols, plumbum, chloride, and anionic surfactants. We have revealed the excess of oil products and phenols and developed measures to reduce concentrations of these substances in the groundwater refinery in Tuapse

Physical and chemical characteristics of the Stavropol oil are provided. The found value of density of 853,6 kg/m3 is low and shows that oil mainly contains light paraffin hydrocarbons. Distillation of test of oil is carried out on the device of rectification of ARN-2 oil to laboratories of the Tuapse oil refinery. On the basis of experimental data, the curve of oil ITK is constructed. The chromotographic analysis determined a mass fraction of C1-C6 hydrocarbons in a model of test of oil. The conclusion is drawn that according to GOST 31378-2009 regulations the sample of oil can be carried depending on a mass fraction of sulfur to the 2nd class ("sulphurous"); on density – to the 2nd type ("averages"); on content of chloride salts, waters, mechanical impurity – to the 1st group; on a mass fraction of hydrogen sulfide, marked - and etilmerkaptan in the amount – to the 1st type. The sample of oil is characterized by the low temperature of hardening (minus 15 °C)

The flowsheet purification of exhaust gases in the Novocherkassk SDPP after the electrostatic precipitator on I-th stage of purification set group cyclone, on the II-nd stage of purification - baghouse. To determine the particle size distribution of fly ash, we selected ash from the transport network to the group cyclone, and the in a group cyclone, and in a baghouse. With the help of the microscope "Biomed- 3" we produced pictures of ash particles with different magnification. Granulometric composition of three selected ash samples were determined according to the mass content of particles of different grain size, expressed in percent relative to the weight of dry ash sample taken for analysis. For size fractions from 10 mm to 0.5 mm sieve method is applied without rinsing with water, for size fractions less than 0.5 mm sieve method is applied with water washing. The particle size of the ash mixture, taken up before the cyclone,

The electric method of gas dedusting is the most effective, since it allows capturing solid particles with a size from 0.01 µm to tens of microns. The efficiency of dust and gas cleaning equipment of Novocherkassk SDPP for cleaning flue gases from ash at power units 1-7 in the period from February 2015 to February 2017 is considered. The main equipment is electrostatic precipitators. As a solid fuel, Donetsk culm is used. It is established that the efficiency of waste gas purification at power units 5-7 was about 99 %, while at power units from the 1st to the 4th this value was within 95-96 %. The data obtained correspond to the design data, but it is recommended that the cleaning devices be improved to improve their efficiency. The most acceptable is a combined electrofilter-bag filter
