Abstract. In this paper is considered the modeling of a monolithic reinforced concrete buildings structures by the spatial plate-core scheme and study of the floor slabs punching problem. When creating the finite element model of the building structure the floor slabs were created by four-node quadrilateral finite elements with 24 degrees of freedom, the columns and beams were created by spatial rods with 12 degrees of freedom. The calculation of the frame has been done by the software complex «SCAD», are got the efforts in the framework elements and are determined the concentration of stresses in the connections of slabs and columns. The program «Calculation of floor slab on punching» has been developed by the high-level language Object Pascal in Delphi environment, in accordance with the design standard which allows to research different locations of columns and stiffening diaphragms on the floor slab. The ratio of bearing capacity of the slab was calculated by means of the software «Calculation of floor slab on punching». Results are well correlated with the program «Arbat» of the software complex «SCAD». Difference of the developed program is in the possibility of considering of the columns and stiffness diaphragm location options on the floor slab (central, edge, corner). Program «Calculation of floor slab on punching» is recommended for use in the design of monolithic reinforced concrete structures.

Is noted that the tool life as the primary optimization parameter should not be used in optimization tasks. Examples of optimization techniques using for investigation and optimization of various technological processes of metals processing, in particular, processing of threads by taps. 

Abstract. Conducted laboratory studies of the threading in the details of ship machinery and ship armatures from hard materials helped to create the modern technology of internal threads of small diameters cutting. The reasons that impede the processing of hard materials are find out.

Presented are various designs of taps for cutting of internal threads and analyzed is their work. Noted are shortcomings of their designs resulting in creating a modern cutting pattern, allowing to minimize the shortages identified in the processing of hard materials. Practice shows that the machining of these materials is difficult because of their considerable tendency to work hardening during deformation, high viscosity, poor heat dissipation from the cutting zone.

They have a low coefficient of thermal conductivity and low coefficient of workability relatively to tool steel. Therefore, processing technology and cutting conditions used for structural carbon steels, often are unacceptable to hard materials.

The most difficult is tapping into the holes of small diameters up to 16 mm. The disadvantage of this technology is the low quality of threaded surfaces and an increased tendency to tap breakage. To improve threading performance in the details of the hard materials are developed advanced threading techniques. 

Abstract. It is proved that the design and the choice of mode require to consider the possibility of condensation from the exhausting air on the cold surfaces of the heat exchangers. The paper considers the numerical method of the regenerative heat exchanger calculation, taking into account the phase transitions (evaporation, condensation). Based on the operating principle of regenerative heat exchangers is proved the need to consider the heat transfer process inside the nozzle. It is proved that the calculation of heat and mass transfer processes in the regenerative heat exchanger of the air-conditioning systems is reduced to the solution of three nonlinear differential equations with appropriate boundary conditions. In the developed model are used the equation of state of an ideal gas and convective heat and mass transfer. The algorithm to solve the nonlinear safe equations on the space-time lattice using Seidel approach is proposed.

Abstract. The paper considers a mathematical model of non-uniform cooling of electronic circuit boards. The block diagram of the system implementing this approach, the method of calculation of the electronic board temperature field, as well as the principle of its thermal performance optimizing are presented. In the considered scheme the main heat elimination from electronic board is produced by the radiator system, and additional cooling of the most temperature-sensitive components is produced by thermoelectric batteries. Are given the two-dimensional temperature fields of the electronic board during its uniform and non-uniform cooling, is carried out their comparison. As follows from the calculations results, when using a uniform overall cooling of electronic unit there is a waste of energy for the cooling 0f electronic board parts which temperature is within acceptable temperature range without the cooling system. This approach leads to the increase in the cooling capacity of used thermoelectric batteries in comparison with the desired values. This largely reduces the efficiency of heat elimination system. The use for electronic boards cooling of non-uniform local heat elimination removes this disadvantage. The obtained dependences show that in this case, the energy required to create a given temperature is smaller than when using a common uniform cooling. In this approach the temperature field of the electronic board is more uniform and the cooling is more efficient. 

Abstract. In the article is considered the modern approach to the assessment of climate parameters on the basis of the thermal comfort indices in accordance with the requirements of GOST R ISO 7730-2009.

Abstract. A new method of determining the stress-strain state of the rocks without dropping its individual parts on the basis of combination of observations of the dynamics of piezometric level in special hydrogeological wells of pre-planned network and by the change in the diameter of wells measured by photo elastic sensors is proposed.

With the beginning of the formation of the stress-strain state of the geological environment, the chaotic structure of hydro-geodynamic field(HGD-field) goes into the abnormal condition of a certain form, in accordance with the geometric shape and sizes of the geological structure. Closed lines of equal abnormal values of piezometric levels form geometric circular structures in the Central parts of which are observed their most anomalous values corresponding to the greatest extent of stressstrain state of rock massif. Within abnormal (disturbed) HGD-field is carried out the measurement of the diameters of the wells, fixed by photoelastic sensors which clarify the concrete stress-strain plot (voltages source) of the rock massif. Well drilled for measuring by photoelastic sensors of changes in their diameters, are arranged in the rock massif in a staggered manner, and the special hydrogeological well, drilled up to an isolated water system for the registration of anomalous (perturbed) HGD-field are locatedin two mutually perpendicular profiles, taking into account the geometric shape of the monitored rock mass. The combination of observations according to a pre-planned network of piezometers and wells with photoelastic sensors will allow to get a more accurate picture of the stress-strain state of the investigated deposits of rock without pass of its separate parts. 

Abstract. The world production petroleum bitumen for road construction is considered. The problems and prospects of the bitumen production in the world and Russia are shown.

At present leading positions on Russian bitumen market occupy the companies Gazprom Oil, Rosneft and Lukoyl. They cover nearly 80% of total volume of bitumen production in the RF.

In world road construction practice the residual road oil bitumen is basically used, from which more than 80% of motor roads are built in the west.

The significant quality growth of oil bitumen was the result of the appearance of modified and polymeric-bitumen bindings(PBB). Amongst block polymer of the styrene (SBC - styrene block copolymer), used in road construction, the main modifier for production of polymer-modified bitumen in the world is butadiene styrene thermoelastolayer SBS (SBS - styrene butadiene styrene).

In 2014 at Moscow NPZ the installation on production PMB of new generation G-Way Styrelf is launched. The installation was built by the joint-venture Gazprom Oil" and French concern Total and is considered to produce 60 thousand tons of PMB and 7 thousand tons of bitumen emulsion per annum. The production is realized in accordance with technology Styrelf, designed by concern Total and adapted to Russian climatic conditions. The Russian bitumen is in demand on foreign market as well. 

Abstract. The successful development of the Russian economy and regions in the conditions of modern market economy is largely determined by the WHO-action control on the process at all levels of economic activity. From this point of view in the present study we examine the theoretical, methodological and practical provisions of the management system creating by sustainable development of the economy, both at the country level and in a separate region. In this aspect, in particular, it is noted that the current management of the economy of the region largely departs from the principles and provisions of the modern theory and best practices. On the other hand, complication and some changes are taking place in external and internal operation environment and enterprises development, industries, complexes and the region as a whole. These provisions stipulate the increasing importance of a new management system formation at all levels of regional economy, providing timely and continuous adaptation to external conditions. Under this approach to the management formation of the sustainable economic development it is necessary to improve the scientific basis, including the ways and instruments of control influence on the process. 

Abstract. It is revealed that the sharp drop in oil prices demonstrated the existing problems in oil-producing countries and created a situation of weakening the economic stability of the Republic of Azerbaijan.
