This paper presents a method for calculating the spread for the generalized (B, S)-market in case of buying up shares. A brief description of the relevance of tasks, related to the calculation of market value of derivative of assets and concomitant calculations. Substantiate the use of Martingale ideology in studies of financial markets. Describes the essence of the generalized model (B, S)-market in case of buying up shares, as well as the principle of calculating of upper and lower value of the option-call European type.

Main areas of modern human life and society (education, work, leisure) require the application of complex human ¬ lovecheskih forces and capabilities - physical, psychological, emotional ¬ tional, intellectual, and spiritual. Difficult transition to a market economy in 90 years, affected the fitness and sports motion, ¬. Socio-economic factors and conditions were the prerequisite for the formation of unhealthy motivations some part of students and the students, and this has a negative impact on their health and physical fitness.

Compressive strength of harden cement paste modified with white soot metakaolin and different superplasticizers ranged from 69 to 182% in comparison with non modified specimen. The elastic modulus ranged from 89 to 137% in comparison with non modified specimenand the measure of creep from 36 to 542%.

Theoretical model of anomalous electron emission has built for an soft x-ray irradiation of surface elektrets, explaining the different character of correlation between energy and emission intensity of ferroelectric solid solution PbTiO3 - CaTiO3 and nonferroelectric ceramics CaTiO3. Shown that due electret surface irradiation the Schottky area is depleted by nonequilibrium charge carriers.

Contract organization of project finance allow to reduce the asymmetric information, limiting the possibility of opportunistic actions of each participant. The back-to-back principle, that is underlying for contractual arrangements, increases total project return and provides transfer and split of highest possible number of risks directly to the contractual counterparty, which is best suited and have the most appropriate instruments to cover this risks. Tripartite deeds of project financing can be considered as a cooperative non-zero sum game, which provides compensation in proportion to covered risk and member's contribution (extent of assumed obligations or provided funds). Multiple contracts of project finance initiatives allow to allocate risks pro rata the ability of participants, without reducing the amount of final win of all parties.
Keywords: project finance, project financing risks, asymmetric information, agency theory, contractual arrangements, back-to-back principle, concession agreement, purchaser contract, tripartite deed, game theory
Requirements for methods of diagnosing design increases - they should make it possible to fully assess the performance of buildings, as well as being simple and mobile, to be used during the construction, operation, maintenance and reconstruction. This work is devoted to the realization of experimental and theoretical methods for vibration monitoring of structures and the analysis of the results. The objects of study are the reinforced concrete beams and slabs, and the subject of the study - the methods of vibration diagnostics, the principle of which is to detect changes in the construction of the main dynamic characteristics. Research has shown that damage to the structure can be detected by the methods considered, using a relatively small number of monitoring points and subject to change only the fundamental mode of vibration.

Given the task of calculating the stresses in the radiation-thermal plant screen. This design, also known as «dry protection» is intended to reduce the effects of radiation and heat, generated in the reactor. A significant redistribution of stresses due to changes in elastic modulus due to the above effects.

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.
The article summarizes the possible changes in the nature of mudflow activity on the basis of projected changes in the natural environment.
