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

METHOD OF POLYMORPHIC VIRUSES DETECTION BASED ON ARTIFICIAL IMMUNE SYSTEM AND GENETIC ALGORITHMS
DescriptionThis article is dedicated to the study of the fundamental properties and components of the immune system such as B lymphocytes, the Tlymphocytes, immune system storage, primary and secondary immune response, immunological training detectors, which will be the basis of the obtained as a result of detection methods of polymorphic viruses using artificial immune systems. Polymorphism of computer viruses is the formation of a malicious program code directly during execution. Thus, it is impossible to create a unique signature corresponding to these polymorphic viruses. A similar classification problem is solved by the immune system of vertebrates, stared again met with the virus, it "remembers" him, and the next time provides effective secondary immune response. These properties of the immune system served as a prerequisite for the use of immune approaches and algorithms for solving the problems of detection of malicious code. The article identified and described their main features, proposed the idea of their implementation and software, system interactions in the immune system revealed such important features, the implementation of which will be effective in solving the problem of detection of malicious code and software. Also, for a more productive system of education is considered a class of genetic, evolutionary algorithms, described by their immediate implementation of site-specific decentralized artificial immune system, built a system of interaction of genetic and immunological algorithms.

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 article is devoted to the development of high-tech metal-working industry, as well as to the use of unmanned technology. We recommended measures to improve the accuracy and quality of manufacturing of complex and large workpieces weighing up to 100 tons. To date, the technical level of many economy sectors is largely determined by the level of the production means. Based on the engineering development there is an overall automation and mechanization of production and industry processes, construction, agriculture, transport and other industries. We analyzed forms of slide sections, of errors affecting the accuracy of the workpieces manufacturing. We made simulation of the cutting forces and sliders deformations. Solved measures increase manufacturing accuracy based on multi-purpose machine tool systems of VM series. We held the analysis of the dependence of cutting forces, a slider form on its strain in different types of processing. We obtained a graph of cutting force and precision manufacturing. We defined the optimal shape of the slider cross section to increase the rigidity and reduce the slide deformation in metal cutting

ZIRCONIUM EFFECT ON THE STRUCTURE AND PROPERTIES OF TINI BASED ALLOY
DescriptionWe have performed a mechanical activation of TiNi powder; as a result, PN47T26TS27 powder after mechanical activation is flat discs ranging in size from 10 to 30 microns. We have developed a composition technology "steel - material with shape memory effect" by high-velocity oxygen-fuel spraying of mechanically activated powder based on TiNi. We have determined the optimal processing parameters to ensure a nanostructured surface layer. We have estimated the process parameters of highvelocity oxygen-fuel spraying. The basic parameters are: propane flow rate 60-85 l / min, that of oxygen 120-160 l / min, flow rate of powder and carrier gas (argon), distance and angle of deposition, and movement speed of the torch, the rotation speed of the coated workpieces. We have carried out macroand microanalysis of surface layers of Ti-Ni based alloy, obtained on proven technology. We have studied the effect of TiNi doping with a third component Zr. The simulation allows us to predict the possibility of using surface modification of products with SME material TiNiZr under certain conditions of temperature and to determine the desired composition of the coating, which provides a positive effect. We have made tests on steel 45 with a surface-modified layer TiNiZr under dry friction conditions, during which there is a significant increase in temperature, we have confirmed the effect of improving the wear resistance
