KALININ A.O.

To date, the problem of the spread of forest fires, is actual throughout the world. During periods of high fire safety, when many fires of forest fires occur, a significant part of them reach the size of large and even catastrophic fires. These fires have the most negative consequences in the ecological and economic aspects - the parameters of the environment are deteriorating (the ratio of oxygen and carbon dioxide in the atmosphere changes, emissions of harmful chemicals are increasing), because of the smoke, the work of air and water transport is disrupted. In this work, a mathematical model of forest fire distribution is considered.

PERSONAL SAFETY IN PROFESSIONAL PRACTICE

GURINA R.R., SOKOV R.S., BARIS E.V., KHRENOVA A.P.

Contracting blood-borne infections and HIV is an extremely delicate issue for every single doctor. Most dentists disregard precautions and don't pay much attention to the common rules in their professional practice nowadays. So, we analyzed the results of a survey - we had conducted - to find out if dentists and students know the requirements for proper oral care aid, and if they do their best to secure their patients and themselves against getting infected.

SCHEMES FOR CONTROLLING REFRIGERATION UNITS WITH DIFFERENT TYPES OF DRIVE

ANDREEV O.P., TAMBOVTSEV M.A.

This article provides an overview of the three most common layout schemes (self- contained, engine-driven or external-powered, refrigeration-heating, generator-powered, computer-accumulating, using refrigerated refrigerants), and installing refrigeration units, each with its own advantages and shortcomings. The main difficulty in choosing a refrigeration system is the impossibility of rapid restoration of the specified temperature conditions during the failure of the autorefrigerator during the loading and unloading of perishable goods, it also depends on the number of openings of the body doors. The world experience in temperature regulation and creation of the necessary microclimate in isothermal vans, tracking of internal parameters, operative regulation of the set characteristics, allows solving the problems ofstorage and transportation of not only food products, but also other perishable goods. Based on this experience, there is a need to use similar technologies in the Russian Federation, depending on the climatic zone, because autorefreviousers are most widely distributed in cities with relatively low mileage. Using only one type of refrigeration system will not solve all the problems of regulating the set temperature parameters. Therefore, it is necessary, on the basis of information on the transported perishable cargo, the climatic features of the region, the duration of the voyage, the number of loading / unloading points, the type of isothermal van to choose the type of refrigeration unit required for the autorefreerer.

The organization of work on case analysis in the course of teaching Russian business communication to foreign students of economic specialties on the basis of video fragments of authentic feature films and television series is considered. The combination of case studies with audio-visual teaching aids, organically integrating communicative skills and subject knowledge of students, increases their cognitive activity and motivation to learn the language for it to be used in their future profession.

THE MAIN ASPECTS OF THE INTERNATIONAL NORMATIVE-LEGAL PROVISION OF ECOLOGICAL SAFETY IN TRANSPORT

NEKRASOVA I.S.

Article is devoted to consideration of the international cooperation in environmental protection and problems of environmental policy on transport. It is shown what from all types of safety (military, ecological, economic and others) ecological is the most relevant today. A number of her problems, of course, perhaps also needs to be solved within separately taken state or the region, but in general ecological safety of inhabitants of Earth can be ensured only by efforts of all mankind. For this purpose the uniform understanding of environmental problems of the planet and the joint coordinated actions of all countries and the people for his overcoming is required.

THE MODEL OF SELECTING OPTIMAL LOGISTICS STRATEGY FOR AN OIL COMPANY IN THE FIELD OF MARITIME TRANSPORT

GORLOV V.V.

Today the greatest share of world shipments of crude oil accounts for two types of transportation: pipeline and tanker. It is very important for each oil-producing region to have accessibility to these types of transport, because it determines not only the possibility of extraction but also sales opportunities the crudes on the world market. About 60% of the total global volume of crude oil are transported by sea. Compared to other modes of transport Maritime transport have certain advantages. First, to transport one ton of cargo takes significantly less fuel, resulting in greater fuel efficiency. This is complemented by huge storage capacity of vessels, which also has a positive effect on unit costs. In conditions of instability of world energy markets, the ability of oil companies to take effective logistics strategy is a clear competitive differentiator. Among these strategies are: hire of the vessel on the free market or the creation of its own transport capacities. Accordingly, it is important to analyze each of the logistic solutions company in order to understand which of them is more profitable. With this purpose, a model was developed to select the optimal logistics strategy for an oil company on the basis of economic-mathematical modeling by Monte Carlo, which can be used in the practice of oil and gas companies as well as large traders with sufficient capital to build a fleet.

TWO-DIMENSIONAL MODELING OF THE FLOW OF A LIQUID THROUGH AN OBSTACLE WITH THE USE OF THE LATTICE BOLTZMANN METHOD

ANDREEV S.A., MATVEEV A.I., ZDANCHUK A.I.

When predicting the flow of liquid through pipelines, it is effective to use computer simulation. Computer modeling is a less labor-intensive and energy-consuming process compared to a physical experiment. Computer simulation allows you to quickly change theparameters of the hydrodynamic process under study, as well as to make observations of the set of studied quantities. In this paper, we present a program algorithm for modeling the flow of a fluid, based on the use of Boltzmann lattice equations (LBM, LatticeBoltzmannMethod). The developed algorithm is divided into functional blocks, each of which is accompanied by comments. The algorithm is implemented by the program in the high-level language "Python" and allows modeling the flow of fluid in two-dimensional space. Modeling uses the "D2Q9" model, and the lattice dimension is defined and specified by the user. Initial data for the model are fluid parameters, geometric dimensions and coordinates of the location of obstacles. The program implements the visualization of hydrodynamic processes by means of the color saturation of the flow elements, depending on the values of the observed quantities. It is possible to observe the process of formation and propagation of vortices. During the simulation, the most important information is entered into the Excel file. It is proposed to test the program by simulating the Poiseuille flow. A conclusion is made about the possibility of modifying and improving the model with the expansion of the range of scientific research. The possibility of using two-dimensional modeling in the design of water supply systems is defined.And also when developing energy conversion devices for self-powered power meters in water supply and irrigation systems.
