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.

The results of physico-chemical studies of micro-and macrostructure of fine-grained concrete hard pressing, used for making bread products for pavements . To improve the quality indicators ( bending moments ) in the fine-grained concrete mixtures were introduced damping additives such as ash microspheres - component slag mixtures . The essence is the replacement of the dense grain mixture with an equal volume of mineral supplements. Ash microspheres have a reduced strength and modulus . Of interest are preserved particles of hollow spheres of additive used , they are responsible for the effect of branching cracks. For experimental studies the author has developed a special method for determining the persistence of particles of ash microspheres after exposure compacting pressure. The quantitative ratio between the phases and composition of the mineral phase were determined by X-ray diffraction and optical microscopy.

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.

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

The technique of the geometrical analysis and the analysis of force loading of combined drills with the replaceable multiface plates is offered in this work. This technique is allowing to determine geometrical parameters and specific force loadings in each point of a plate’s cutting edge taking into account its orientation in the drill case. Application of this technique allowed to establish the reasons of the drill’s low durability. The offered technique allows to design drills from the minimum unbalanced radial component of cutting force which increases its working capacity and the processed holes quality. New designs of combined drills both with two, and with three replaceable multiface plates are offered in this work. The durability of this new drills is increased by the plates mutual turn for the minimization of an unbalanced radial component of cutting force

Disassembling of NPP equipment, systems and metal constructions is a compulsory procedure in the final stage of NPPs work cycle, namely withdrawal. Disassembling technology is closely linked with some necessary conditions, that is why some mandatory requirements must be fulfilled.
The disassembling tasks can be carried out with the help of modern tech-nologies, means and instrumentware. The system of task-oriented engineering and adaptation to the environment and its conditions provides informational and me-thodical supporting in the process of developing the technology of equipment dis-assembling.   
This article presents the common methods and practical recommendations for developing the technological process of disassembling of NPP equipment.

The economic approach towards trust gives suggestions how a causal role of trust could be established experimentally. And the biological and behavioral evidence indicating that trusting is not just a special case of risk-taking, but based on important forms of social preferences such as betrayal aversion. The results show that a high level of trust is an important determinant of the effectiveness of cooperation as well as a key component of reducing transaction costs.
