Mathematic model considers the geometrical and physical nonlinearity, the adaptability of creep flow. Arc work is accounted for by the method of constructive anisotropy, but with due regard for shear and torsion rigidity. In solving physically nonlinear problems, secant modulus is defined directly from the «σ-ε» curve, found experimentally. Mathematic model is written in the form of functional of total deformation energy. This model can be used for comprehensive analysis of the stability of reinforced shells of revolution.
Keywords: stability of reinforced shells of revolution, linear-elastic problems, the nonlinear-elastic problems, the problem of creep flow.
Petro graphic analysis of the structure of foam concrete, reinforced with glass dispersion and synthetic fibers showed that the real nature of the fiber controls the parameters of their structure and strength.

The results of the analysis of existing approaches to the determination of the efficiency of trapping pollutants at their sources of isolation, as well as the prediction of residual contamination of the air of working areas. The classification of methods for determining the effectiveness of local suction ventilation systems. Given the technological distinction between the concepts (factor "technology capture") and sanitary (factor "technological breakthrough"), the efficiency of local suction. The tasks of improving the mathematical description of both types of efficiencies.

It is shown that to describe the phenomena and processes in a transition interfacial layer having a certain thickness, it is useful to distinguish the boundary layer of the surface and boundary diffusion layer, which lies entirely in the less condensed phase related. In accordance with this energy and power characteristics of the transition layer should be attributed to the boundary surface of the interphase transition layer. The basic equation of electro capillary boundary of the surface layer, establishing the dependence of the surface tension of this layer on the chemical composition of the second phase, and bordering the jump of electric potential between them.
