Results of researches on improvement of quality of the brick made of clay Kagalnik-3 raw materials are presented. It is defined that raw materials contain a large number of particles less than 1 mm in size that complicates receiving press powder of the recommended granulometriya. In addition, because of high sensitivity of raw materials to drying, on samples there are drying cracks influencing durability and frost resistance. It is defined that for receiving qualitative products, except softer mode of drying, for increase in physico-mechanical characteristics it is necessary to add the mineral modifying additive to furnace charge, and to carry out preparation of press powder with preliminary plastic granulation of weight.

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.

Have been given the substantiation of the need for preliminary testing of concrete beams on the transverse force. Their goal is to determine the effect of inclined cracks formed at the operating load levels, on the efficiency of the composite reinforcement in the near support sections.   The results of these tests, obtained with the shear span 1,5h0; 2h0 and 2,5 h0, that significantly affects the nature of inclined cracks. According to the results of an experiment formulated recommendations for the design of composite reinforcement.

In the construction of linearly extended objects, there are difficulties related to the optimization of flows. This requires the rational distribution of construction machinery fleet. The stream will be optimal only in the case when all processes are performed optimally. Rational distribution of the fleet is that the volume of construction works between the machines assigned in accordance with their highest load. Thus the performance is improved when in-line method of construction, which, in turn, should reduce the cost of socially necessary labor per unit produced by this company products

The principles of intelligent node of electroengine - brush are discussed. Into the brush an optical fiber sensor of wear and temperature on the basis of serial low reflection fiber Bragg gratings (FBG) is embedded. In contrast to existing, developed sensors are complexed and are able to simultaneously measure the temperature of the shift of the central wavelength of laser radiation reflected by the FBG, the amount of wear by means of registration the change in the length of the FBG arrays. Analysis of the signal reflected from the FBG allows you to define the parameters of the engine speed, temperature changes - the state of brush-collector unit. At a resolution of the interrogator in the wavelength about 2 ps the temperature sensor has resolution 0,2 ° C. Measurement error values of wear sensor, ​​determined by the stability of the amplitude parameters of laser radiation, are near tenth part of micrometer.

In article the factors defining efficiency of roadheader technology application of transport tunnels construction are considered. As one of the factors containing growth of carrying out speed of tunnels is the loading part of the combine, in article the analysis of the factors influencing efficiency is made. Stochastic process of interaction with the destroyed mountain weight is considered. The analysis of the developed approaches to determination of executive body loadings productivity with loading paws with a destroyed mountain weightstack is made. Influence of a form of the immersed material particles and geometrical ratios of loading body and average fineness of material particles is analysed. It is revealed that extent of influence of a particles form doesn't exceed the statistical errors arising at research of loading process of lump mountain weight, and geometrical ratios have significant effect on loadings and productivity. When determining loadings it is offered to apply model taking into account linear proportions coefficient, and it is necessary to apply the model considering influence of active volume on formation of system output characteristics to calculation of loading part productivity. Taking into account influence of the described factors, the calculated value of productivity and loadings increases in comparison with the generalized models that confirms expediency of use of the described dependences.

Prevention is a priority direction of development of Russian health care system. Currently in development is a large number of dental disease prevention programs, but it is there is no system to provide reliable data on their effectiveness. At the same time it is essential to improve the dental health of Russian citizens. Moreover, to increase the effectiveness of such measures, it is necessary to adjust the preventive measures depending on the region. At the moment, there are many GIS, reflecting the environment, the composition of drinking water, climatic and geographical conditions, but these data are scattered, do not correlate with the incidence of dental and unavailable for use in the clinical acceptance of a dentist.affecting the state of the dental system.
