A design of the actuator, consisting of a thin layers of silicon dioxide and aluminum is proposed. There are calculations made of the response speed and heat dissipation of the actuator. By making the best selection of layer thicknesses and optimization stages of technological process, in particular the deep selective etching of silicon, the best performance on the angle of inclination of the actuator and the speed of the device could be achived. The greater the difference between the initial temperature and the heating temperature, the stronger the beam of the actuator is lowered to the plane of the silicon plate, and, therefore, less angle of elevation above the surface of the silicon plate. It is thus possible to control the angle of the beam by selecting the appropriate heater and voltage, providing the desired temperature. The design of the micromirror device based on the proposed actuator is provided. The developed design is based on the actuator and allows for controling the tilt of the mirror in a wide range.

    In this paper we evaluate the viability of cell suspensions with the assessment of their bioelectric properties. A method for evaluation of cell suspensions, based on the method of pulse impedance. The frequency response of the electric impedance of suspensions chondroblasts, determined by analysis of the transition function. Under the transition function is meant to test the reaction of the object exposure, for which current is used as a reaction - voltage electrodes placed in the sample suspension. After the time-frequency transform data to a PC, the transfer function is considered in the space of states that characterize the electrical properties of multicomponent biological tissues, which allows us to go to the electrical equivalents of its constituents. The measurement process, i.e. impact on the sample cell suspension is carried out within the pulse of electric current, which allows a quick assessment of the cell suspension.

  This article describes the purpose, functionality and the main field of application of hardware-software complex "MYOCOM". In particular, the criteria determining structures are described by the schema and the hardware capabilities of the device to register electromyogram. Program-methodical maintenance of the complex is divided into three groups: research section, which allows you to plan and assess the results of the experiment; analysis of the functions of the muscles on EMG parameters; rehabilitation exercise equipment on the basis of biological feedback. The paper describes the possibility of synchronization of the complex "MYOCOM" with other devices.

The paper reports on dynamical model of optimal biological resource exploitation with corruption. Particularly, it is allowed a fish quota increase after paid a bribe. The research has been realized with the sustainable development conception by the Pontryagin's maximum principle. A time moment, where the bribe is profitable, is considered. Fight corruption methods are presented.

Development of urban areas, especially Rostov-on-Don, which is one the largest city of the south of Russia, should be based on a comprehensive assessment and analysis of the structure of housing stock and engineering services, which provide all types of resources for the city. Research of the structure of housing stock, analysis of residential and private housings, municipal and business buildings, information on the territorial distribution of these objects with reference to the topography would allow to create a reliable information base for the development of district heating schemes. Housing stock of Rostov-on-Don was ranked by the year of construction, number of floors and material of the wall. The article assesses the providing of municipal and business buildings, kindergartens, schools, institutions consumer services, culture and sport institutions.

  The thermal mechanism of the effect of acoustic waves with high intensity for biological tissues is required thorough study. When considering the high level of acoustic wave used isentropic Poisson adiabatic usually. Used isentropic shock adiabatic (Hugoniot adiabatic) for description of the waves with increased intensity. In the case of shock waves with different density of the medium would be discussed is the following approximation in the description of the process – non-isentropic shock adiabatic, which has an asymptote already. This is important when considering the process.

In the conditions of becoming of the new technological mode the special actuality is acquired by the choice of strategic directions of development of industrial sector of economy. In this connection there is a necessity of analysis of dynamics of development of industries of industrial sector. The model of analysis of structural dynamics intensity that allows to estimate branch distinctions in the industrial sector of economy is presented in the real work. By means of this model is possible to define the measures of stimulant character in regard to industries with the different level of economic development, and also to educe perspective directions of structural transformations to the industrial sector of economy.

The article describes the historical features of the formation of the industrial sector of the Russian economy. The analysis of the current state of industry, allowing to determine the dominant technological structures in the industry. Identified priority areas for the new technological system and the basic problems of Russia's transition to a new wave of technological development. The role of the cluster approach in the transformation of the industrial structure.

The article is devoted to the peculiarities of eclecticism in the central part of the city of Rostov-on-Don at the turn of the XIX - XX centuries. The Russian architecture in the years 1840-1850. prevailing eclecticism. All the variety of its variants is reduced in the Russian architecture in two varieties: the first of which dates back to the tradition of a warrant (neogrek, Renaissance, Baroque, Rococo, pampeyansky), and the second - to the non-classical heritage (Byzantine, Russian, Gothic, Romanesque styles). In Rostov architecture became widespread both varieties. This was facilitated not only the diversity of life in the city, the intensive development of trade industry, generating a variety of new types of buildings, but also the technical progress by which the means of production have changed.

The article is devoted to a brief presentation style features Constructivism in the city of Rostov-on-Don. The construction boom in the city begins with the 1920s, a new style of Constructivism, had already fully declared itself in the capital. In the early 1930's. architectural development in Rostov took the path of development of the principles of the avant-garde. The very principles and forms of avant-garde come to the Rostov practice with some delay - as a kind of well-established tradition, continuity of development projects in Rostov architects
