In recent years reconstruction of buildings and constructions became one of the main directions in the field of construction. Considering that at reconstruction capital investments it is significantly less, and payback is higher, than at new construction, the share of capital investments in reconstruction will increase.
It is necessary to apply intensive methods of repair and reconstruction of buildings and constructions as one-time costs of reconstruction and repair there are less than one-time costs of new construction in construction production. Considering a significant amount of the factors significantly influencing the organization of construction at reconstruction of buildings and constructions, previously before development of organizational and technological documentation it is necessary to prepare the list of the data necessary for the organization of construction works and to make their analysis which concerns the analysis of projects and the territory of a building site, including situational plans.

Questions of improvement of the organizational mechanism of interaction of participants of construction are considered. In the conditions of weakening of state regulation, self-regulation with its collective joint liability of members of SRO has to become one of the main regulators of activity in the monitoring system of quality of construction. Ensuring integration of local systems of quality management of participants of construction has to be carried out on the basis of the regulations including requirements to system of document flow, to procedures of transfer, acceptance and modification of the design and estimate documentation, structure of executive documentation, an order of survey of the hidden works, requirements to information interfaces between local IT.

Alzheimer's disease is an incurable illness. It affects about half a million people in Russia, and due to the general trend towards aging of the population the number of Alzheimer's disease cases will steadily increase. Insoluble deposits of amyloid beta in the brain tissue (amyloid plaques) are the major morphological characteristic of Alzheimer's disease. It has been found that the increased concentration of copper in amyloid plaques results in copper ions bound to the protein. It is the presence of copper in the binding site triggers of the formation of amyloid plaques. Therefore, the study of the binding site in amyloid beta is of great scientific interest. The local atomic structure of the Cu(I) copper ion binding site in the amyloid beta peptide has been studied by means of XANES spectroscopy. Several model structures obtained by molecular mechanics and density functional theory (ADF code) have been tested. Theoretical analysis of X-ray absorption spectra based on the finite difference method implemented in FDMNES code was performed. An appropriate model structure of the Cu(I) copper ion binding site in amyloid beta peptide has been found.

We study the problems in the propagation of acoustic waves of a sound range near the boundaries of media. The features of the wave processes occurring at the water-air interface, due to the influence of inhomogeneous waves. Considered in detail the properties and parameters of an inhomogeneous plane wave. The mathematical calculations of the transmission coefficients L.M. Brekhovskikh for spherical and cylindrical waves through this boundary, allowing to take into account the contribution of inhomogeneous components. It is shown that than the frequency of radiation of a source is lower and the closer it is located to water-air interface, the acoustic transparency of this border is higher. Study of the dependence of the transmission coefficient of the water-air interface at low frequencies can have important consequences in a number of fundamental and applied problems. Increase the transparency of the interface requires a reassessment of the feasibility of acoustic communication from water in the air, the detection of underwater sources without dipping into the water and acoustic monitoring of the physical processes occurring in the water.

Keywords: Inhomogeneous plane wave, water-air interface, transmission coefficient, wavelength, spherical wave, acoustic impedance.

The authors of the article examine the problem of electrothermal degradation of fiber optical communication lines arranged on the high-voltage power lines pylons. The possible methods of reduction of high-voltage line electric field influence on fiber optical communication lines were studied. There is also the method of possible calculation and choice of optimal suspension place for fiber optical cable on a high-voltage line pylon. This method can be applied for one of the high-voltage line masses disposition cases.

Piezoelectric ceramics on the basis of the phase of (1-x) PbTiO3-xPbZrO3 is the basis of most high-performance piezoelectric materials. Electrophysical and mechanical properties of these materials can vary widely in different ways. Traditional methods include changes in composition within the morphotropic region and doping. Now is the study of the influence of topical makrolegirovaniya the material properties of the PZT system. As a model system was selected phase of the PZT system, the compositions of which MO belong, one of which contains a dopant in the sublattice (A) and another - in the sublattice dopants (B). The studies established that one of the effective ways of varying the parameters piezomaterials may be the formation of solid solutions on the basis of two or more piezoelectric phases having different combinations of electrical parameters
