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

The article considers the problem of maximum flow of minimum cost finding in fuzzy dynamic transportation network. The relevance of the problem is in its wide practical application on the rail, air, sea and other roads in finding of routes of minimum cost. The feature of the problem statement is that fuzzy nature of the network parameters, such as arc capacities and costs is taken into account. It allows us to make decisions more sensitive to environmental changes. The dependence of network parameters from flow departure is also considered, that allows to introduce the notion "dynamic" network as opposed to "stationary-dynamic", examined in the literature. The algorithm for solving the described problem in fuzzy conditions is proposed. To illustrate the algorithm a numerical example is presented.

Keywords: dynamic network, maximum flow of minimum cost, fuzzy numbers, arc capacity, transit time

"Examines the relationship of the concepts on the example of post-war reconstruction of post-war reconstruction of the city of Rostov-on-Don.
In 1945, the Chairman of the Committee on Architecture AG Mordvinov announced seven conditions under which you can create the city.
In 1945, the development of the urban plan of rebuilding the city of Rostov-on-Don was appointed academician of architecture VN Semenov.
In 1949. master plan was finalized at the construction site.
In general, the basic idea of the architect was executed. Among the fifteen cities prone to restore the city of Rostov was restored in all seven conditions put forward by the Chairman and the Committee for Architecture AG Mordvinov, projected architecture academician VN Semenov and given a reality by means of the chief architect of YA Rehbein."

Briefly discussed the theoretical model of the spectrum of RR intervals and its changes depending on the processes taking place. Made a device for measuring cardiointervalogramms (CIG). Obtained from the renting of data, of varying duration and frequency shall be recorded for further processing. The analysis revealed that the resulting spectrum satisfies the conditions considered in the theoretical model, and can be further analyzed with fractal characteristics. Such an analysis is of great importance in the diagnosis of the patient directly to the duration of the therapeutic procedure for the optimization of both time and intensity exerted influence.

Keywords: CIG; fractal series; the spectrum of RR intervals

The titanium dioxide synthesized by an electrochemical method is a perspective material for use in solar elements and catalysts of cleaning of water and air environments. Regularities of electrochemical synthesis of titanium dioxide in glycerin dilute solutions (1:1) in the presence of ammonium fluoride at 2-14 V are investigated. Mathematical scheduling of synthesis process according to plans of first order with use of the complete three-factorial experiment is carried out, the adequate regression equations for formation processes of a titanium dioxide in the field of potentials 8-14 V are received. The electron microscopy method proved porosity of synthesizable layers of titanium dioxide. Water content influence in electrolyte on the speed of electrochemical process and potential size influence on titanium dioxide materials yield is established. It is shown that under the chosen electrolysis conditions electrochemical process is accompanied by the considerable chemical disolution of a titanium. Electrochemical processes in water containing glycerin are investigated by a cyclic voltammetry method. It is established that at electrochemical oxidation of Ti in water containing glycerin (1:1) porous TiO2 with a materials yield no more than 25% is formed.
