Currently, special attention is paid to creating a comfortable urban environment, as a result of this there is a need to create projects that contribute to improving the quality of life of the population. In this paper, we consider two subprograms of the Rostov region: "Improvement of public territories of municipalities of the Rostov region" and "Improvement of the courtyards of apartment buildings in the Rostov region", operating under the state program "Formation of a comfortable urban environment." The number of transformed public and house territories from the moment of implementation of these subprograms of the Rostov region is analyzed.

he article is devoted to the question of selection of aerodynamic parameters of drying in the apparatus of the filtered-fluidized bed of dispersed particles – carbon-black containing wastes materials and granules of sodium salts in solution of modeling problems. The design of the studied gas pressure distribution grid fluidized bed of dispersed materials of the tray kind provides the possibility to efficiently fulfill the drying process at relatively low speeds of the drying agent. It is allowed to reduce the removal of particles of material from the bed and its exhaust into the atmosphere. The average flow rate of gas motion and the number of fluidization for the main stages of the filtered-fluidized bed of the studied materials and aerodynamic parameters (drop pressure losses) are determined. It was found the fluidization number in the range 1.25-1.5 and the bed height was about 0.25 m. The total aerodynamic drop pressure losses of the dispersed materials’ bed and had acceptable meanings within range from 90 to 130 kg / m2. For the recommended range the coefficient was equal 30-45. Data were obtained on the phases of fluidization, the values of the aerodynamic parameters of drying, and the areas of operating conditions that provide a fairly uniform circulation of the material in the layer and reliable operation of the apparatus.

This article attempts to present the author’s symbolic model of the language, with an emphasis on the practical value of the model for resolving language conflicts. A weighty justification is given for the possibility of a symbolic interpretation of practically any phenomena and objects of reality, which can serve as a methodological key to decoding a single sociocultural code. Such an approach may indicate the discovery of a new vector in understanding the nature of language conflicts. In the model below, you can see many ideas that can provide a rich methodological arsenal of great heuristic power in the field of resolving various kinds of language conflicts

In modern industry, more common motor choice is a permanent magnet synchronous motor (PMSM). This becomes an urgent issue for the implementation of control scheme for such engines: their mathematical description and the further hardware implementation of algorithms for field programmable gate array or for microcontroller. In this article a mathematical model of PMSM control was created, including a power unit with an inverter and an engine, a FPGA based control circuit with its internal interconnections of digital elements and a feedback sensor. In the future work, this model can be taken as the basis in the hardware implementation of the PMSM control system using CAD, for example, in such as Altera's Quartus II.

When forming in the process of centrifugation an annular section by the method of ""separate"" concreting with the formation of a section of the product at the first stage from the original, including fine-grained concrete mixture, and with the introduction of a coarse aggregate at the second stage into the formed circular section, followed by the final formation of the section and compaction of the concrete mixture by centrifugation, the speed, calculated for the compaction stage, increases, depending on the section zone, the concrete compressive strength from 20% up to 47%, the initial modulus of elasticity from 6 to 19% relative to single-stage centrifugation. The ratio vint / vext of ultrasonic pulse velocities for surface sounding along the inner (vint) and outer (vext) faces of a centrifuged annular section can be considered as a conditional indicator of the uniformity of the concrete structure over the cross section of a centrifuged product. Key words: centrifugation, separate concreting, structure homogeneity, strength and deformation properties, porosity.
