Currently, laser annealing are widely used to create a polycrystalline silicon film, which is promising for use in thin film solar cell, and transistors, liquid crystal displays and sensors due to recrystallization of amorphous and nanocrystalline silicon films. The study of morphology and surface conductivity of single-crystal silicon film on a glass substrate by laser annealing power. Laser annealing is carried Nd: YAG laser with a wavelength of 532 nm, speed of movement of the stage with a specimen of 5 mm/s and a laser power ranging from 34 to 86 watts. The laser beam was focused on the sample in the form of a narrow line width of 10 microns and 60 mm in length. The dependence of the size of the nanocrystals and the conductivity of silicon films on the power of the laser annealing radiation. It is shown that the power of the laser radiation in the range of 60 to 70 W is optimal for the best electrical parameters silicon film for the purpose of its use in high-performance thin-film solar cells.

The calculation of multi-storey reinforced concrete frame building, consisting of apartments, offices and underground parking, against progressive collapse is presented in the paper. Two different ways of simulation of reinforced concrete building against progressive collapse are suggested, needed for estimation of survivability of building structures. The technique, which allows to carry out the stability of reinforced concrete structure to resist progressive collapse, is presented. This method is based on a nonlinear analysis of framed structures under the special load combination and includes dead and live loads, implying that the loading process modeling is fulfilled on the basis of the adjusted step method. The last one is of great importance for simulation of the processes in the whole life cycle of structures. The obtained results show that the offered strength calculation method of the framed structure against progressive collapse considers both geometric and material nonlinearity and also allows to assess survivability of the construction under conditions of emergency events and its stability to resist against progressive collapse. The step method of solving nonlinear problems, applied for modeling of collapse process, is shown to be more appropriate for these cases. We conclude that applying the proposed method of calculation results in more economic use of materials, giving evidence of its effectiveness.

A numerical model of the laser annealing TiO2 film on the TCO / glass substrate with radiation of a wavelength of 1064nm (Nd: YAG laser) to the crystallization and its use in solar cells perovskite. The modeling used a numerical finite difference method for solving a system of one-dimensional unsteady heat conduction differential equations. As a result, laser annealing temperature distribution obtained in the process of modeling the structure of TiO2 / TCO / glass substrate by varying the laser power. It is shown that a high laser power (30-100 watts) is enough for an effective transition organometallic precursor of TiO2 in the crystalline phase of anatase TiO2 (transition temperature of 400-600 °C) for a short period of time (60 sec.) due to the direct absorption of photons laser radiation. It is found that for experimental studies should be used laser power of 30-70 watts, since a higher power (e.g., 100 W) raises the temperature of the substrate above its melting point (for example, for glass 650 ° C).

The market in Russia is common formwork caisson ceilings SkyDome system.In the article the question of the effectiveness of ribbed caisson ceilings in multi-storey monolithic buildings compared to with .flat slab floor. The program complex "Lira-CAD 2013" calculated the 18-storey residential buildings with monolithic framework. Consider in detail the reinforcement floors typical floor in two versions: a flat of 200 mm and a caisson plate of 50 mm and beams with a section of 200х350 mm with a step of 900х900 mm. Analysis of the results showed that in a building with columns a step of about 5 m difference in cost of materials for the manufacture of the overlap was about 1%. Efficiency gains are expected by increasing the span up to 8 ... 10 m

Family is the most important actor in cultivating values of trust in the youth environment, however, the effectiveness of implementing this feature of the Russian family is limited to the trends occurring on the macro level and marked by a lack of trust in society, both at the macro and micro levels. Very clearly a crisis of confidence manifests itself in the urban environment of Russian society. Eventually, trust transforms into a family value that identifies the microcosm of the family interactions. The reality of the external world to the world of the family, urban youth perceive as socially unjust and full of distrust, determines, in the end, and the low trust rating in the system of values of young Russians.

The paper describes and analyzes the main development trends of Russian forestry machine-building in modern conditions. Russian forestry machine-building enterprises do not use presently available perspectives in import substitution in connection with the depreciation of the rouble. Neither do they use the opportunities for producing integrated multifunctional machines. Development and production release of forestry machines for assortment harvesting based on Russian-manufactured tractors fitted with technological equipment of foreign manufacture is the first step on the way of creating domestic vehicles of analogous purpose. These machines will be fully complete with home-produced technological equipment. This will allow reducing the costs on the production of these machines and on their timber-harvesting operations

Presented by the authors in the article an analysis is made of the safe childhood and the authors, on the basis of the concept of research, offer safe to consider childhood as a social phenomenon that characterizes the process of socialization and maturation of the personality from the standpoint of the creation of all necessary conditions for the formation of its physical and social health. Under the social health of the young generation authors is understood as a state of well-being considered from the perspective of primary family socialization, parent-child relations, the system of socialization of family values and preferences, ethical and moral norms of family society, a reflection of the attitude of parents to their children. The main conclusion by the authors, is that childhood in modern Russia is gradually losing safe features that, in turn, defines a deep interest in the issue of childhood in Russia and the need for timely diagnosis and sociological well-being/ill-being of childhood as an indicator of future social, spiritual and physical condition of Russian youth.

In article questions of nonlinear interaction of acoustic waves in the air environment in the course of distribution are considered. Is shown that the nonlinearity coefficient in the air environment considerably exceeds that in water therefore generation of secondary waves in the air environment is more effective than in water. The main characteristics of interaction pay off. For realization of the parametrical antenna for information transfer the narrow beam offers to use as converters in the rating antenna high-frequency loudspeakers with high sensitivity in the radiation mode. For reduction of level of side petals in the characteristic of an orientation of the antenna of a rating are given the recommendation about an arrangement of converters in the antenna of a rating and to their coordination with Wednesday by means of acoustic loud-hailers. As initial parameters for calculations passport data of loudspeakers get out. Characteristics of the parametrical antenna at its arrangement in air streams are analyzed. Interaction of waves in a stream is described by the non-uniform wave equation in which the member from a convective derivative estimates influence of a stream. Are considered the non-uniform equations for various working out the resultant generated signal the parametrical antenna in the environment with an air stream. Expressions for calculation of additives to the signals generated in a homogeneous environment for distribution of waves of a stream perpendicular and parallel to the direction are removed. It is shown that the air stream in a near zone of the antenna of a rating increases amplitude of the secondary waves generated by nonlinear interaction. Recommendations about use of the parametrical antenna for information transfer in the air environment are made.
