Description
Currently, there is increasingly reduced number of the sites convenient for construction. In this regard there is a question of development of new territories, for various reasons which were earlier considered economically unprofitable or unsuitable for construction. Often, for construction in the mountain area it is necessary to carry out construction of objects in landslide territories. However, landslide processes constitute big health hazard and lives of people and also safety of buildings and constructions. The main objective of engineers when performing design and exploration work on landslide territories is the determination of stability of slopes and size of landslide pressure from soil and also identification of the most dangerous combination of loadings which can demand design and construction of a construction against landslide of landslide protection structures with significant load-bearing capacity. The research presented in article allows to define the most dangerous loads affecting the stability of the slope and also of the selection of a protective construction (against landslide). Dependences of change of landslide pressure and coefficient of stability of a slope are received from action of various loadings (both static, and dynamic)

RESEARCH OF PROVIDING INFRASTRUCTURE OF MINERAL FERTILIZERS TO AGRICULTURAL CONSUMERS
DescriptionCurrently, for producers of mineral fertilizers one of the main tasks is the process of creating a supply chain of mineral fertilizers delivery to agricultural consumers, running on a «Just-in-time» way. The effective operation of such a supply chain has to be influenced by many factors, including: the technology of agricultural production, seasonality of agricultural work, the structure of the distribution channel of mineral fertilizers, the geographical features of consumers, the availability of appropriate infrastructure, etc. Critical elements of the infrastructure are warehouses and equipment for storage of mineral fertilizers, as well as the road network. For example, farms in the Rostov region were analyzed for the infrastructure necessary for the successful supply of mineral fertilizer agricultural consumers. It was found that the capacity of warehouses and facilities for the storage of mineral fertilizers and distribution of cultivated areas between agricultural enterprises of different size are diametrically opposed. The process of delivery of mineral fertilizers need to be developed taking into account the shortage or complete lack of storage capacity for their storage, especially for small enterprises. The existing road network, with paved allows us to deliver of mineral fertilizers virtually all consumers by road transport. This dictates the feasibility of delivery of mineral fertilizers to consumers by road transport in soft containers (Big Bags), allowing the storage in the open air

RESEARCH OF QUALITY, SAFETY AND CONTENT OF BIOLOGICALLY ACTIVE SUBSTANCES OF FOOD RED BEET
DescriptionThe article presents results of research of quality, safety and content of biologically active substances of food red beet roots of Bordo 237 variety, grown in the Krasnodar region in 2014. On the basis of the research carried out it was established, that there are carbohydrates, proteins, organic acids and mineral substances in the food red beet roots of Bordo 237 variety. Food red beet roots are a source of dietary fibers (pectin, protopectin, hemicelluloses and cellulose), possessing antitoxic, antioxidant, radiation protective, cholesterol-lowering and lipid correcting qualities, and also a source of vitamins C, B9 (folic acid) and P-active substances, possessing antioxidant properties. Due to high content in food red beet of a complex of microelements – iron, zinc, manganese and copper, and a complex of macro elements – potassium and magnesium, it can be recommended for prophylaxis and treatment of hypertension, atherosclerosis and other diseases of heart and vascular system, and for prophylaxis of iron-deficiency anemia. Thus, the research of quality, safety and content of biologically active substances showed that food red beet roots of Bordo 237 variety are a high quality component ingredient for creation of food products of specialized and functional purpose

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
