In the field of the Museum exposition design in Russia and abroad considerable experience has accumulated. However currently we can state the absence of a comprehensive approach to create a coherent exposition system Exhibition – exhibition space. In this scientific article we formulated the concept of Space-graphic element. We have identified the structure, types and variants of use of space-graphic elements, as a special category of exposition tools in exhibition spaces. We have identified the main technical and compositional principles of space-graphic elements design. The use of those principles will allow organizing a coherent unity system Exposition – exhibition space. Concept of space-graphic elements is useful in the development of Museum and exposition activity.

Keywords: Space-graphic element, Museum-exhibition space, exhibition, principles of design, modularity, transformation, interactivity, integrity, structure, consistency

"This article is devoted to the development of the method for modeling elements of microsystems technology(MST) of membrane type. In this paper perforated membranes are considered and the impact of perforation on the mechanical properties of the membranes is examined. In numerical simulations of the elements it is proposed to use the equivalent mechanical parameters of perforated membranes obtained at the initial stage of the simulation. This will allow to obtain find the optimal parameters of perforation, reduce the time and resource modeling of MST elements. To test the technique numerical experiments were conducted for the two square membranes with sides 1.5 and 3 mm fixed on the contour of the same thickness. We studied the influence of the size of the perforation on the equivalent Young's modulus of the perforated membrane. "

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.

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.
