PRESENTATION OF MANDATORY POLICY OF ACCESS CONTROL VIA THE HARRISONRUSSO-WILLIAM’S MODEL
DescriptionThe accepted model of the access control is realized with the monitor of safety in the protected automated information system. Models of safety are considered, as a rule, as a system which is a single whole and has the uniform monitor of safety. Nevertheless, the architecture of the real automated information systems and processes of their functioning can be characterized by distribution. The distributed automated information system consists more than of one local segment representing isolated set of subjects and objects of access. In the distributed system local segments can be realized both on the basis of discretionary, and on the basis of mandatory models of safety (i.e. to be diverse). One of directions of a safety in this case is realization of the general monitor of the safety providing the uniform (coordinated) policy of access control. For safe interaction of patchwork systems it’s necessary to bring them to a single model. Hence, while the integration of information systems the problem of their interaction becomes persistent. Thus in the systems processing the information of a various level of confidentiality, it is necessary to realize mandatory access control. In given clause the mandatory policy of the safety presented by classical model of Bell-LaPadula, is described by the elements of classical model of Harrison-Russo-William. Using the mechanisms of change of a matrix access the opportunity of assignment and change of confidentiality marks is described and the observance of safe practices within the limits of mandatory access control is analyzed. The safety of application of the given approach has been proved. The perspective direction of research has been defined

VIBRATION TECHNOLOGY WITH A LARGE AMPLITUDE OF PARTICLE MOTION OF FEED COMPONENTS
DescriptionThe article has revealed the contradiction between the way of technological impact and the means of implementation of technological transport in existing processes of feed preparation. There has been shown the possibility of eliminating this contradiction by menus of completely new technological equipment on the basis of relative screw drums and the opportunity to improve their productivity. There are no exciters in the offered design of vibrating machines. There is no need for them because the move mend of mass loading particles is provided by the original constructions of relative screw drums committing a rotary motion around its own axis. For implementing of feed preparation process the geometry of the relative screw drum and its dynamism must be individual: the shape, spatial orientation, the impact of forces providing feed components particles simultaneously with rotational-translational and vibrational motion. In the result, the continuously running through the inner cavity of the relative screw drum particles of feed components perform rotational-translational movements with super imposed vibrations inside this drum, due to this process the particles of feed components are mixed intensively

Description
In Russia, as well as in foreign practice, classic yogurts are more required. Depending on the value of imported dry starters, the proposed technology allowing reduction in their quantities in yogurt technology is very crucial. It will affect the cost of the finished products. In yogurt technology, the possibility of using physical techniques, with the purpose of intensifying the process of producing yogurt, is very little reflected. Pre-activation of the leaven by electromagnetic field – lower frequency before fermenting in the production of yogurt is one of the technological tricks that speed up the fermenting process and reduce the quantity of starters. The advantage of the proposed technology is its ease of implementation, not requiring additional cost of electricity and also enhanced maximum reduction of additional chemicals which are used as raw materials to create a special environment for the growth of microorganisms belonging to the leaven. In this work, the overview of the existing principles for accelerating the fermentation process of milk is given. In this work, the research results of accelerating technology of fermenting milk for yogurt are presented. Mathematical process of experimental data enables the optimization, fermentation process using leaven FD-DVS YF-L812 10Yo-Flex. The optimal temperature and duration for the maximum acceleration of the process of obtaining yogurt at a given frequency of electromagnetic field are identified. We have given organoleptic characteristics of yoghurt prepared using the activated ferment

Description
Тhe article presents an investigation of hydrodynamic mixer for biodiesel production from vegetable oils hyperacidity in the conditions of agricultural companies. The process of hydrodynamic mixer which mixes the flow of biofuels from jatropha oil with carbon dioxide to wash it. The regularities of disclosing the relationship of the parameters (diameter and length of the mixing chamber), the mode (the pressure and flow rate) from the medium (dynamic viscosity, density, elasticity) to the energy characteristics of the process (mixing power on). Based on the method of similarity and dimensions of physical quantities obtained criterion turbulence. A reduction in the flow pressure and agitation power with increasing diameter. We have justified the mode (pressure at the nozzle exit corresponds to the critical), in which the carbon dioxide gets into the mixing chamber properties of liquids, solutions for biofuels, and the mixture becomes a quasi-homogeneous. Based criteria of regime change from a supersonic flow in the subsonic, allowed us to determine the condition of quasi-homogeneity of the mixture. It is proved that we form a supersonic flow liquid-gas at the same time it is transformed into subsonic, accompanied by the acoustic cavitation effect leap remixing due to isentropic pressure jump. The article justifies the physics of cavitation effects of carbon dioxide on biofuels, result of which is to improve the physical and chemical properties of the medium due to the structuring of the molecules of the solution, which has a positive effect on the mixing

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
