he main reason interfering effective steady activity of the self-regulating organizations (SRO) in construction branch,
risks are. The risk is closely connected with the concept "uncertainty". Application of innovative approach allows to allocate two approaches to ensuring competitiveness of the construction organizations: marketing and integrated. During research the risks interfering stability of the self-regulating organizations in construction are revealed. The reasons of emergence of these risks are analysed, recommendations about their prevention are made. Minimization of approach of subsidiary responsibility according to obligations of members of the self-regulating organizations is especially considered.

Considered the questions connected with estimation of mechanical properties of steel elements of metal construction. The measurements are performed in a non-destructive method on the basis of the analysis of the characteristics of the implementation of the conical indenter in surface materials. This method allows you to get the values of all mechanical characteristics of metal. The measurement of mechanical characteristics can be made to anywhere in the design. At the same time, when large amounts of construction and large volumes of measuring works, you need to evaluate a sufficient number of measurements in a particular place. Proposed and implemented the Bayesian method of consideration of a priori information to reduce the number of dimensions and complexity of the process of receiving mechanical characteristics.

Operation of sylvinite ore desliming is an important step of potassium chloride production by floatation method. It is known that ultrasonic treatment is applied to increase the efficiency of insoluble rest separating from an ore. The purpose was to establish kinetic regularities of the insoluble rest removal from sylvinite ore crystals of the same particle size distribution. Investigations were carried out with mechanical stirring and sonication of varying intensity. It is established that process of sylvinite ore desliming occurs in the diffusion mode. Application of ultrasonic treatment allows to intensify process in 2-4 times as compared with mechanical desliming. Influence of sylvinite ore treatment parameters to chemical composition changing of the insoluble rest is defined. It is shown that sonication for 90 seconds leads to removing carbonates from ore crystals withal concentrating of the iron compounds.
Keywords: desliming, sylvinite ore, ultrasonic treatment, sonication, insoluble rest.

"The mechanical properties of the rubber-cord composite in strengh analysis are described. There is an algorithm of the numerical estimation of the effective (average) properties of the rubber-cord. The effective properties are defined by the successive application of different deformations to the representative volume of the rubber-cord composite (tensions along each coordinate axis and shifts in each cooridinate planes). The effective properties are defined in form of the generalized Hooke's law (for anisotropic materials). A serias of computations in estimatition of the effective properties of double-layer rubber-cord composite was carried out based on the proposed algorithm. The dependence of the effective elastic modules of rubber-cord on the angle of cord was explored. The according graphs are represented in the article."
