The article is devoted to the architecture of the three known manor houses in Pompeii (2^nd–1^st centuries BC), such as Vettii, Pansa, Faun and Albucius Celsus (house of the Silver Wed-ding). Two of manor houses built in the broken country are described, namely the House of Championnet and Villa Diomedes. An attempt is made to identify the dependence of the architectural solutions of these buildings and the social and occupational status of their owners. Ancient Greek traditions (peristyle courtyards, home gardens, mural painting, etc.) play an important part in a radical reorganization of their internal space. Urban planning aspects, functional-planning structure of the three estates, particularly their facades, architectural elements, mural paintings decorating their interiors, building materials are considered in this paper. Interior fresco paintings, building materials and engineering innovations (heating and water supply systems, living and utilities areas are also discussed herein. Special attention is paid to household comfortable furniture for home owners, their guests and servants.

The article is devoted to the wooden architecture of Tyumen late in the 19^th and early 20^th centuries and shows the problem of conserving the originality of historical cities of Russia. Insufficient serviceability of wooden architecture, overpopulation, unsuitable restoration techniques lead to huge losses of valuable historical and cultural heritage. We see less and less authentic wooden carving replaced by new one without any historical value. A study of Tyumen wooden architecture indicates its individual properties and problems connected with preserving wooden cultural heritage.

A.D. Kryachkov made a significant contribution to the development of sustainable architecture in Siberia. He studied intensively the interaction of architectural objects with the environment and developed therefore a efficient and flexible solution for his buildings. Owing to the systematic, ecological approach, highly artistic works of architecture in Siberia were created with such qualities as resistance to unfavorable climate conditions, durability and efficient operation.

The paper is relevant due to changes in the city-plant Votkinsk situated in the Urals. These changes condition a loss of architectural and artistic originality of the city. The purpose of the paper is to reveal its town-planning features. For the first time, the stages of its urban development are identified empirically on the basis of the complex analysis results on the historical and architectural heritage of Votkinsk. The research results can be used for the formation of the concept concerning the properties conservation of Votkinsk.

The paper presents the research results and design work on town-planning and traffic development in the right-bank Tomsk-city which covers the area from the river Ushaika entry to Kommunal'nyi bridge. The analysis of the planning concepts is given herein and new approaches are suggested to the traffic arrangement in this territory.  Computer simulation is used to analyze the variants of street and road network, and the suggested optimum decision provides a gradual development of this territory. As a result, the traffic load in the center of Tomsk-city will be reduced.

The paper presents two iteration algorithms for the equation solution using the method of Lagrange multipliers. It is shown that these iteration algorithms do not converge. For comparison, we use the optimum parameters of a ribbed plate obtained by other methods. The proposed method is based on the specific properties of optimality of ribbed plates formulated as a result of the Lagrange equation analysis. These optimum parameters satisfy each of Lagrange equations. The solution of these equations shows that optimization of ribbed plates is possible only with the use of specific optimality properties.

The paper suggests a method of synthesizing a granulated sorbing agent for sewage purification from ions of heavy metals (copper and zinc). The raw material mixture includes iron sludge produced by water treatment, liquid glass, caustic limestone, and water. The optimum mass ratio of 10:1:14:4 (dry iron sludge, calcium oxide, liquid glass, water) is selected for the mixture composition which provides the high strength and water resistance of sorbing agent. The paper considers the preparation and the optimum thermal treatment conditions which ensure the strength, appropriate porosity and specific surface of specimens. Research results are obtained for mechanical-and-physical properties of synthesized granular sorbing agent. The static exchange capacity and the extraction degree of copper and zinc ions from model saline solutions are detected herein. Research results contribute to the problem of the efficiency improvement of closed water utilization systems and can be used in utilization of large-tonnage water treatment wastes, thereby providing sewage purification facilities with inexpensive sorbing agents.

The paper presents research results on the use of silica rock in the production of lining ceramic brick. The analysis of clay samples showed that they are non-sintering raw materials. The dependence is obtained between the firing temperature and the average density of ceramic brick. It is shown that the firing temperature depends on the material composition with the product water absorption. The relationship is detected between the firing shrinkage, density, and water absorption. The experiments on silica rock sintering show that the ceramic brick made therefrom has a low average density, increased firing shrinkage, porosity and water absorption. Silica raw materials can be used in the ceramic brick production.

This paper presents research into a possibility of synthesizing a silicate melt based on oil shale combustion byproducts obtained in  Dalian Province (China). The energy of thermal plasma is used for this in the mineral fiber production. An experimental electroplasma unit is developed to provide melting of refractory nonmetallic materials, the stationary power of which is 30 kW. During the melting process of the mixture, the formation of the gaseous phase is observed. Using scanning electron microscope, maps of the qualitative distribution of the elemental composition on the surface of the melting product were obtained. Using the scanning electron microscope, the elemental composition maps are obtained for the melting product surface.

The paper presents research into changes in the ultrasonic velocity (Rayleigh wave propagation) at plastic deformation of the type 40Kh13 corrosion-resistant high-chromium steel with a sorbitol structure after high-temperature tempering (original state) and after electrolytic hydrogenation saturation for 12 and 24 h. The method implementation for measuring Rayleigh wave propagation includes a periodic generation of square-waves 100 nm long. Measurements are performed at the input of a radiating piezoelectric transducer including the wave propagation over the specimen using a receiving piezoelectric transducer connected to a digital oscilloscope. Measurements show changes not only in the deformation curve at uniaxial tension but also in the dependence between the ultrasonic velocity and deformation.
