MECHANICS
Using the fictitious settlement schemes based on equivalence of influences in mechanics of a deformable solid body the intense deformed states are received for the beam on two support which is under the influence of mass forces; the rotating thin round disk; the dam of triangular cross section which is under the influence of volume filtrational forces.
Method of magnetron sputtering targets polycrystalline SiC-AlN on substrates SiC and Al2O3 thin films received solid solutions (SiC)1-x(AlN)x. The methods of Xray and electron microscopy studies the structure and composition of films. There are factors that determine the composition and structure of films, as well as conditions for the formation of monocrystalline films of (SiC)1-x(AlN)x to the substrate SiC. The basic technological parameters of process magnetron sedimentation of films (SiC)1-x(AlN)x are calculated.
In work, for the purpose of increase of extent of compression in the cylinder of the internal combustion engines (ICE) it is offered to use the modified piston and the device for determination of frequency of the vibration formed by working process in the combustion chamber.

The design of the device for producing melt water with the use of thermoelectric converters.
The article deals with the analysis of a new object, called a system with bitmodular organization for which to solve the problem of monitoring and diagnosing.
BUILDING AND ARCHITECTURE
The goal is to increase effectiveness of seismic isolation of buildings with flexible rubber-seismic isolation bearings (RSIB). In order to reduce the maximum displacement RSIB installed in the basement of frame buildings in seismic isolation system introduced elements of dry friction. By integrating the original system of differential equations of motion of the systems under consideration, the parameters of the seismic response of horizontal seismic shear forces, the maximum movement of the masses and maximum displacements RMSO in a wide range of seismic predominant period of the ground motion. By comparing the graphs and tables show the values of seismic response of seismic isolation system combining an advantage with rubber mounts with the elements of dry friction.
Experimental data on the effect of the age of autoclaved aerated concrete with and without carbonation factor to change its physical and mechanical characteristics, as well as by the amount of creep deformation and degree of reversibility. It was found that the solution of applied problems creep theory for structures of autoclaved aerated concrete, in accordance with their carbonation from the effects of atmospheric carbon dioxide, it is necessary to use the theory of elastic-creeping body on the basis of function creep measures in the form proposed by prof. S.V. Alexandrovsky.
Given problem optimization calculation of structures considering seismic hazard. Optimization conditions are presented based on probabilistic and economic criteria. For buildings with possible non-economic effects of a restriction on probability of failure, the amount of which is determined on the basis of the limitations of intangible losses. Seismic risk territories to evaluate as projected over the lifetime of a building influences with the relevant probabilities of occurrence and spectral parameters or in the form of calculation akselerogrammy. The feasibility of the methodology is shown in example Building with large bays with steel columns of the composite section dvutavrogo.
Work is devoted to theoretical researches of calculation of the three-layer designs (TLD) at dynamic loading by the concentrated loading. On these theoretical researches graphic and analytical dependences of relative thickness of punching of freely reinforced filler (SAZ) on its density and height of discrete pyramidal filler by which in case of need it is possible to determine the necessary density of SAZ for this speed of hit of the drummer are given.
This paper gives a brief analysis of the use efficiency of non-metallic materials, mainly shale, which are in great demand and have a low cost in production of building materials. The results of experimental studies of production of the multifunctional low-calcination bulk ceramic material from shale are presented.
The work is dedicated to the calculation of the stress-strain state (SSS) of the three-layer beam (TLB) subject to boundary effects.
In this paper, a system of differential equations of equilibrium of the threelayer beam. To solve these equations, it is necessary to know the 12 boundary conditions, co-which depend on support conditions and loading of sandwich beams under study. This system of equations is solved by the application package of mathematical modeling "Maple 5.4." The solution of this system we obtain expressions for determining de-formations and stress all components (bearing layers and filler), a three-layer beam anywhere under specified conditions of fastening the ends of the beam and its loading.

ECONOMIC SCIENCE
The modernization of the Russian economy is impossible without a systematic approach to the development of a modern infrastructure of housing and communal services. This requires the adoption of measures to improve the efficiency of the housing stock, the modernization of municipal infrastructure, improve the quality and reliability of delivery of municipal resources, introduction of modern technologies. Problems of housing and communal services are particularly relevant for urban areas - areas of cities and towns where there is an extensive network of engineering infrastructure. The analysis of development of the municipality "City of Makhachkala" showed that although the municipal administration carried out serious work on the development of housing and communal services, today in the field of city life is still a lot of unsolved problems.
The package of measures, directed on improvement and further development of the housing-and-municipal sphere is developed.
They are offered conceptual bases of the shaping the situation management by process to realization of the working the building project. The main indicators of the structured description of works of the construction project are specified. The designed methods of work execution management on result and time to their realization.
They are considered main problems to segmenting market to premises and moving the real estate on him. It is motivated that correlation quality and cost realized object to premises must be balanced with buyer's ability of the consumers on corresponding to segment market. The offered managerial system operation, conducted on the market with real estates.
The notions «production costs» and «expenses» of building enterprise are elaborated. The designed methods warning regulations of the expenses of the building enterprise. The different approaches are considered to shaping the vector of the factors, characterizing expenses of the building enterprise and model of the expenses as object of management in the manner of «black box» that allows to organize their efficient regulation on deflection and indignation in sloppy economic ambience.
