The paper considers the architectural and construction activities of M.G. Arnold, the first architectural engineer of Tomsk State University. According to scientific publications, his activity remains in the background and even receives a negative assessment in memoirs of contemporaries. In addition to traditional printed sources, this paper includes information from the hand-written journal of the Committee for Construction of Siberian University Buildings in Tomsk. These data allow to show the activity of M.G. Arnold in detail and identify his contribution to the initial stage of construction of Tomsk State University in 1880. The location of the hall for laying of the foundation stone is graphically reconstructed, including the memorial plaque.

The paper considers the general trends in classicism and city planning in Russia and Siberia. The prerequisites for the classicism development are studied on the example of the famous architectural monuments; the main style characteristics are considered. This study concerns the problems of preserving historic buildings in the cities of Russia and the loss of valuable building elements. Classical architecture offers simple clean design widely used in the 19th century and recognized as a background building in all cities of the country. It was most of all subject to destruction during the Soviet period. At present, these objects are rare and identify the architectural era. Although many authors study classicism in the cities of Russia and Siberia, the city of Tomsk has not been studied enough.
Comparative and architectural analyses are used to study the classicism development in the capitals of Russia, Siberia and in Tomsk, in particular. It is shown how the main public buildings are designed and built in the cities of Russia and in the city of Tomsk in accordance with the approved projects.
It is shown that having passed the main formation stages, classicism becomes the national style by the middle of the 19th century. The need to build public buildings in all provincial cities of the country, new types of buildings such as magistrates, seats, banks, stock exchanges and others, change the architectural style in Russia. The model projects allow in a short time to carry out a large-scale economical and technically correct construction, which contributes to the stylistic integrity of the Russian cities.

The paper identifies the current, previously unexplored problems of industrial architecture of small and medium business entities on the territory of the Southern Federal District. The purpose of this work is to detect an optimal solution, taking into account the specific economic conditions of the country. The paper presents the research results of small and medium-sized enterprises in the Southern Federal District. The current problems and factors which define the architecture of these enterprises are described herein. It is shown that the general economic dynamics changes the significance of these factors and, as a consequence, the nature of design solutions.

This work is aimed at studying the origination, formation and development of the first institutions in England for abnormal children. The analysis of historical documentation, books, photographs from the collections of the Russian and foreign libraries, and recollections of employees from these institutions help to reconstruct of the building architecture and planning. The study determines the basic laws of the building creation, change, extinction and advantages and disadvantages of the architecture affecting the comfortable conditions of buildings. The latter are intended for the non-trivial functional purpose and reflect the historical connection with the architecture of the building complex. The historical experience is important for further study in this area.

The paper proposes a different approach to the process of prospective settlement instead of the modern urban model of the spatial development in Russia. The proposed approach involves large settlements and connections considered as an interaction between several systems and networks (environmental system, transport system, economic links between settlement nodes, fluvial network), the density of which is determined by the territory, relief, landscapes, environmental qualities and economic potential. This gives rise to a different typology of territories that constitute the land use map, the pattern of which is determined by the landscape matrix. A study of the landscape elements makes it possible to identify their influence on the settlement development and connections of any system or network. The understanding of the basis for the formation and interaction of different systems allows to accurately predict the urban development of the settlement system. The paper predicts the routes of development of the settlement system in West Siberia.

The article presents the results of historical and architectural research into and a scientific hypothesis about the location and architectural and spatial organization of the lost medieval fortress in Novorossiysk. The problem is that information about this object contradicts the data that can currently underlie the correct interpretation and study of the fortress history. Confusion is caused by the fact that four fortifications on the territory of modern Novorossiysk locate in close proximity to each other. They are built almost at the same time. The article focuses on the Sudjuk Kale fortress. The results of archival research show the lack of accurate data on the location and spatial organization of the fortress. The comparative analysis includes the description of travelers and aerial photographs of different periods that clarify the entire structure and shape of the fortress components, and the data on the architecture and spatial organization of other medieval fortresses. The research results determine the structure, shape, size, material of the fortress walls, the presence of the moat around the fortress, four towers at the corners and four entrances at the cardinal points. The obtained results include the new data, computer model and virtual reconstruction of the Sudjuk-Kale fortress.

The administrative building, built in Leningrad in the 1930s, is an example of Soviet buildings unique from the point of view of their functional purpose. This building, a central element of the Moskovskii region (Lerningrad) is designed with regard to the urban spatial organization. The results of this study can be used in the design of new administration buildings in the country. The history of the territory formation is considered, and a graphical analysis is utilized as the main analytical approach. Based on the gathered experience and the obtained results, the quality of the modern administration buildings can be significantly improved. The paper proposes to create a specific territory around the administrative building of the Moskovskii region that can be used more appropriately.

The criterion for the minimum material consumption of strips strengthening the I-rod with stability or first eigen-frequency limits is formulated in previous studies for the case of continuous change of the variable parameter. It is known that this solution allows evaluating a real design project not only by the criterion of its proximity to the minimum material consumption, but also by the reference point in the real design. In many cases, it is used to replace the continuous change in the variable size of the rod-strengthening piecewise constant sections. The boundaries of these sections are based on the minimum material consumption. The width of the strengthening strips is determined by the optimization methods. The paper proposes the criterion allowing to correctly assess the termination of the optimization processes.

The paper considers the improvement of the process conditions for the extraction of high-quality components from solid municipal waste (MSW) for the manufacture of heat-insulating products. A new approach to waste processing with the component extraction is required, and new materials are being sought for heat-insulating products.
The purpose of this work is to select the optimum method of MSW segregation, which will be applicable to the morphological composition of wastes in Russia to obtain cleaner raw materials. The main problems of waste segregation are high content of organic waste polluting the components and equipment, low automation and recovery coefficient of waste components due to a single run of waste.
The main research methods include a comparative analysis of technological and environmental criteria and labor costs of MSW segregation differing in Russia and abroad.
The proposed new method of MSW segregation requires new approaches to the waste use for the production of modern materials. The first problem to be solved is MSW segregation and preparation for further utilization. A search for new, eco-friendly, safe and economically feasible heat-insulating materials is important in the construction field. The proposed method will increase the recovery rate of waste fractions and productivity per unit time.

The paper proposes methods for protecting the internal silicate-enamel coating of pipes in field conditions. It is shown that the proposed methods are highly efficient for manual mechanical cutting, chamfering, cutting edges with abrasive tools with vulcanite cutting discs for welding, in manufacturing and assembling the engineering systems, transportation of aggressive products, and fire fighting systems.
It is shown that the most appropriate method for preservation of the internal silicate-enamel coating is its preliminary annular incision and sizing of the cut place with a thin cloth (calico) impregnated with quick-drying glue, and clay coating protection from hot metal particles. This method is recommended to be used when cutting pipes, fittings, segments, processing their chamfers and cutting edges, in manufacturing of network nodes (fire-fighting systems) in field conditions.
The proposed methods will significantly increase the operating life and reliability of engineering networks with silicate-enamel coating for the transportation of aggressive products and, as a result, technical safety of trouble-free facilities.

This paper describes the influence of non-standard particles on the matrix of the concrete system. It is found that in the concrete dispersion systems, the formation and development of the spatial structures occurs with the different degree of their occupation with non-standard particles. The introduction of non-standard particles in the concrete matrix leads to the formation of strong structural bonds due to the particle interaction through the adsorption and diffusion layers. The latter appear during the formation of sub-microcrystalline helium surrounded by newly formed dispersion regions (C-S-H). The scanning electron microscopy is used to verify the formation of the structural bonds in the concrete system matrix.
