The paper analyzes methodological issues of how regional markets develop, the role which they play in regional economy as well as spatial, institutional and reproduction aspects of the structures of such markets. The author, having analyzed different theories of regional markets, validates the approaches to a concept of the regional market development which allows coordinating interests of governments and businesses.

he paper considers an optimization model of plannig the investments made into a regional touristic complex. A criterion for choosing an effective plan is based on synergistic effect. One of the advantages of such model is the fact that a criterion function and a set of constraints are represented as linear functions that allows solving a problem of rather high dimensionality.

The paper analyzes major opinions and evaluations of Russian experts in regional policy and federate relations concerning the issue of what model of federalism would be appropriate to Russia and what impact it would have on the spatial development of the country. As the analysis shows, the experts' opinions are mostly defined by their evaluations of how advanced the political institutions of federalism are and to what extent they are effective. Most experts consider essential, and even inevitable, the decision making to be decentralized and the independence of regions, and municipal units to be extended.

The paper considers methodical issues of how to assess regional ratings. To illustrate this problem, the ratings of the regions of the Siberian Federal District are presented. The author proves his choice of a two-phase and two-criterion technique to assess ratings as well as to make "soft", i.e. grouped ratings. However a basic argument is beyond the technique and consists in idea to apply more flexible criteria to assess the quality of governance in RF units.

The paper is devoted to the question of whether a true-savings index - a sustainable development indicator - well known in western scientific publications, could be applied to assessing the sustainability of regional development. The author made an effort, through a case-study for the Samara Oblast, to measure a real speed of national saving after deduction of human investments, depletion of physical capital, natural resources and diseconomies of environment pollution.

Numerical simulation of convective-radiative heat transfer in an enclosure with a heat source in the presence of heat-conducting walls of the finite thickness was carried out. The distributions of both local (streamlines, temperature fields) and integral (mean Nusselt numbers at typical interfaces) characteristics describing specific features of the investigated process in a real range of the variation of determining parameters were obtained. The radiation influence scales at thermal modes formation were determined. The effect of transient factor on the fields development of both hydrodynamic and thermodynamic characteristics was analysed. Correlation ratios for determining the mean Nusselt number at solid-gas interfaces were obtained depending on the Grashof number.

It was demonstrated that by analysing temperature field of the outer surface of the spacecraft it is possible to determine its orientation - directions to the principal heat sources within the Solar system, including the Sun and the nearest planets. For the spacecraft with the simplest configuration, this problem can be solved analytically. In the real spacecraft there shall be simple heat-sensitive elements with weak thermal bond with the spacecraft and high sensitivity to the changing outer thermal conditions. The experiment has proved that the accuracy of orientation determination with the use of such temperature measurement reaches 5 ang. min at the rotation velocity of the spacecraft up to 30 ang. deg /min.

The effect of repetition time of powerful rectangular pulses on their dynamics was studied numerically on the basis of hydrodynamics of superfluid turbulence. The plane, cylindrical, and spherical situations are considered. Calculations were carried out without mass transfer (the second sound), which corresponded to experimental conditions. Numerical results are compared qualitatively with experimental data.

Herein the fundamentally new unit for production of silicate refractory melts with the use of high-concentrated heat fluxes is considered. Mathematical model describing temperature fields in skull layer in the process of the plasma flow interaction with the particles of refractory silicate material has been developed. Typical numerical results of temperature distribution in various sections of the skull layer are presented. Numerical and experimental data have been compared, and their fair agreement is obtained.

The mathematical model of heat transfer between the counter flows of gas and porous batch  of anthropogenic wastes in the working area of a shaft furnace is presented. This model considers chemical transformations in separate batch components and radiation heat transfer between the gas and solid phases. Results of calculations are presented.
