The article is devoted to the formation of scientific and methodological basis of socio -ecological and socio-economic risks that arise in urban areas in the process of realization investment and construction projects for the development of the urban environment. The authors identified the contradictions economic substantiation of development projects of territorial development and socio- environmental factors, the adverse effects of their realization, on the basis of which concluded the need for modernization of the basic principles of risk management for sustainable development of urban territories . The article proposes a set of principles that are required for the formation of an effective system of risk management of investment and construction projects of development of urban territories, which includes five interrelated principles : the principle of the matter of feasibility activity, the principle of optimization of protection, the principle of an integrated estimation of the danger, the principle of ecosystem sustainability, the principle of "the polluter pays". The proposed principles will gain the efficiency of the analysis and selection of projects for realization only able to provide the highest level of security and stability of the socio- economic sector of the city.

The nano-catalyst ceria (CeO2), activated by Pt nanoparticles, is known for being prospective and efficient material widely used in catalysis, fuel elements, and sensors. One of the most up-to-date methods of catalysts' reasearch is X-ray absorption spectroscopy (XAS) that is sensitive to the chemical state of catalyst's active centers [1,2]. Using XAS in the fluorescense detection mode at CeL1 line with high precision we studied electronic structure of Pt-activated nanoparticles of ceria at various redox conditions. In order to detect partial X-ray fluorescence yield the emission line CeLγ3 was used, which allowed us to increase spectral resolution. We researched local atomic and electronic structure of the materials under study. Oxygen vacansies were found to appear on the nanoparticles surface of ceria at 5% CO He atmosphere. Theoretical modeling of the obtained spectra at CeL1-edge demonstrated good agreement with experiment.

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.

To describe the dynamics of the temperature field in the surface layers of the earth taken up the heat balance of the earth's surface. Taken into account are three components of the heat flow: convective heat transfer with air, solar radiation, heat flow from the surface layers of the soil. The boundary conditions on the surface of the soil is considered the temperature of the ground surface, which is determined from the heat balance of the surface layer of the sun radiation. The temperature distribution in the soil is determined using the method of finite differences. A layer of soil has a certain thermal inertia, which leads to delaying the achievement of minimum temperatures in the soil column relative to the time of achievement of the minimum surface temperature. In the surface layer of soil to a depth of approximately 300 mm, is almost complete attenuation of the diurnal temperature fluctuations in the month of June with account of solar radiation in conditions of the South of Russia.

The problem of manufacturing technology heterostructures pezofaza - metal considered in the article. Complexity consists in the fact that during the removal of the polymer in the system at low temperatures are formed porous layers, formed powders separated metal layers, having island macrostructure. One way to solve the problem - reducing the firing temperature heterostructures. Proposed to decrease the sintering temperature by using of functionally active glass-phases. Reducing the sintering temperature of products also allows to replace platinum electrodes inexpensive silver-based alloys. Obtained by solid state reaction method of piezoceramic material has a low sintering temperature (980 ° C) and high electrical parameters. Found that not only the proportion of the vitreous mass, but also their qualitative influence on the properties of piezomaterials
