The salutogenesis concept is widely used in a healthcare system, but many architects of hospices do not use this term. This paper describes the key aspects of the salutogenesis concept, work on patient adaptation in palliative care facilities, which directly affects the building architecture and organization of the planning and functional model.

The salutogenesis concept is based on three types of internal resources that support and strengthen health, their combination provides a coherence or forward movement, which resists to the entropic forces of disease and infirmity. The coherence consists of resources that improve: manageability (the ability to maintain homeostasis and physical function); resources that improve comprehensibility (the ability to see order and meaning even in uncertain situations); resources that enrich the meaningfulness, significance (desire and reasons for resisting illness). The paper considers the theoretical aspects of the salutogenesis concept for creating specialized institutions.

The paper presents a sparing approach to the tourist and recreation development on Lake Baikal. This is conditioned by several factors: lack of sufficient theoretical basis on the regional architecture, the participation of the government, federal programs and projects on the development of tourism as an important socioeconomic sphere; high pollution and the constantly deteriorating ecosystem of the lake.

The aim of this work is to develop a concept (model) of sparingly developed tourist and recreation places on Lake Baikal, a choice of types and principles of placing objects and their main architectural and functional properties. The paper presents the analysis and synthesis of the data from the Federal Target Programs, literature, methodologies, regulatory and design materials on the problem.

As a result, the proposed model of sparingly developed tourist and recreation places includes intensive, normal, moderate and promising development. The main principles for the object placement are based on the mobility of stationary objects from the coastline, creation of research centers responsible for constant ecosystem monitoring, and traditional and fishing centers. These solutions allow creating the functioning system of the tourist cluster, interesting tourist routes and their architectural and functional diversity.

The study concerns the formation of human capital determined by the level of education, the quality of higher and secondary special education. Changes in social, economic, technological, and information fields require the territorial organization of higher and secondary special educational objects, namely, the formation of educational clusters of various profiles. The purpose of the study is to develop the concept of the city planning of the educational cluster in the Kazan urban agglomeration, determine its specifics and profile, taking into account the socioeconomic prerequisites for the territory development. Research is based on the documents of strategic and territorial planning of various large-scale levels, the field analysis. The data analysis and systematization are based on the literature in the field, Russian and foreign experience in the design of educational clusters, modern trends in the architectural and spatial organization of campuses. The proposed urban planning model for the formation of the agricultural educational cluster on the territory of the Verkhneuslonsky municipal district and the architectural and planning organization of its center in Innopolis.

The formation of this cluster on the territory of the Verkhneuslonsky municipal district will provide the growth in the Kazan agglomeration. This decision is aimed at transforming the existing monocentric planning structure of the Kazan agglomeration. The center of the educational cluster in Innopolis will allow the city to strengthen the city-forming base, contribute to its socio-economic development. The identified principles of the educational cluster, architectural and urban planning approaches to the organization of the campus can be used to organize other specialized educational clusters in the Republic of Tatarstan.

The aim of the work is to form conceptual solutions of the ecological and archaeological site "Donskaya Troya’. The unique archaeological site founded in the 17th century, BC by the tribes of the North Caucasian catacomb culture locates westward Rostov-on-Don, on the right bank of the Mertvy Donets River, between Karataevo and Liventsovka villages in the Soviet region. The stone fortresses discovered by archaeologists in the 1960s, are the oldest in Eastern Europe. The preservation of the Liventsovka archaeological ensemble is very relevant, since today it is in a deplorable state, namely excavations with bushes, dacha garbage dumps, dilapidated walls and ditches filled with stones. The media quite keenly discuss the sad fate of this territory. The paper proposes to create a museum to show the unique historical and cultural potential of the Karataevo and Liventsovka fortresses, which will be and open-air museum, a festival space with a research center and other educational and entertainment areas. Urban planning, scenario-functional and artistic-figurative concepts of the museum relate to the existing historical and cultural artifacts, the ideas of a "living ethnic landscape", the life of people from re-created times and modern trends in the design of museum complexes.

The paper presents the development of approaches to the crack detection in metal rod structures based on the analysis of the lowest eigen-frequency modes. Full-scale experiments and numerical calculations are carried out, and the obtained results are compared. A vibration analyzer is used for full-scale experiments, and numerical calculations are performed by using Autodesk Inventor. With regard to the internal friction, the antinodes of various vibration forms were identified using a specially developed program. The model includes sensors for the the field experiment as masses affecting the frequency-response characteristics. The dependences are obtained for eigen-frequencies in the presence of cracks and for the crack locations. The polynomial dependences of the crack location on the lowest eigen-frequency modes of the rod can be used to analyze the crack position of in cantilever beams.

Technical solutions are considered to provide the structural rigidity, module safety during the installation, storage and safe transportation.

The determination of mobility of the concrete foundation on a natural subgrade is rather relevant for the strength analysis of multistory brick buildings with a spatial cross-wall structural system. During the inelastic soil behavior, its ultimate limit and elastoplastic states are allowable along the concrete foundation perimeter, the bearing capacity of the foundation being provided as a whole. In this case, it is important to adhere to the standard conditions of the foundation deformation and mobility. The finite element modeling of the stress-strain state of the concrete foundation and the building superstructure of the base-foundation-building system is performed in the MicroFe software package. A consideration of inelastic soil deformations in the natural subgrade results in unacceptable displacements of the concrete foundation.

The standardized indicator is the heat transfer resistance as the main factor that plays the main role in assessing the energy efficiency of the thermal envelope of a building. During the last decades, the climatic conditions change toward the increase in average daily temperature in the summer period. Thus, the thermal resistance of external wall structures becomes more and more urgent. This problem is reduced to an assumption that the heat flow in the wall structure is directed from the external surface to the internal. This paper analyzes the heat flow distribution and redistribution in time in the wall structure. The paper presents a comparative analysis of the modelling and calculation results of the nonstationary heat flow for solving the thermal stability problem.

The article deals with the problem of purification of melt water generated by the urbanized territories. It is proposed to use wood residue from sawing of plantings to obtain relatively inexpensive sorption material for the contamination extraction from surface wastewater. The aim of this work is to study the sorption properties of the material obtained by sawing of plantings. Experimental modeling of sorption of dissolved petroleum products and copper ions from an aqueous solution of milled branches of black poplar is carried out under static conditions. The sorption process is studied in accordance with a three-factor design experiment. Laboratory modeling determines the optimum parameters of water purification and the degree of mutual influence of contaminants on the sorption process. Natural material obtained from the poplar components shows the sorption properties in relation to oil products and copper ions in the water environment. The filters made of milled branches and used in local treatment plants will allow solving the problems of municipal services, namely utilization of wood residue from sawing of plantings and effective melt water purification due to the low-cost filtering materials.

The paper considers the production of heat-insulating paints using ash microspheres as a microfiller. It is shown how the technology factors change the properties of paintwork materials based on Latex DL 424 water-dispersion acrylic latex and 0.071–0.14 mm ash micro-spheres with the bulk density of 371 kg/m³. The optimum composition of paintwork materials is determined with regard of the coating production of the required quality. The experiments result in the increase in the coating strength and hardness due to the intensive polymerization of styrene-acrylic latex in ash microspheres. It is found that the obtained samples also possess high adhesion to ceramic and metal substrates, high corrosion resistance and low thermal conductivity. In addition, the use of the polymer binder in the composition makes allows increasing the coating elasticity and, as a consequence, the resistance to washing and abrasion. The obtained heat-insulating material can be used for various surfaces of walls, ceilings, roofs of buildings and structures, pipelines, boilers, and many others.

The property control of concrete mix and hardened concrete is an integral part of the construction process. With the development of additive manufacturing in construction, the methods of assessing the properties of concrete mix and concrete are characterized by the formation of their structure and properties in concrete laying and curing. Currently, there is no regulatory documentation on a reliable assessment of the concrete mix and concrete quality for additive manufacturing. The purpose of this work is to propose a method for determining the concrete strength for additive manufacturing. The proposed concrete mix composition matches the technological requirements for 3D printing equipment and possesses the required properties. The concrete strength analysis and research methods are carried out in accord with the Russian State Standard. The paper describes the main problems of the concrete quality control in using additive manufacturing and proposes methods for determining the concrete strength properties for 3D printing.

The paper considers the dynamic stability of submerged pipelines with denudation and sagging depending on their stiffness and the river flow rate. The hydrodynamic force frequency and natural vibrations of the pipeline are calculated at the actual and critical length of the pipeline sagging. It is shown that the frequency of the external hydrodynamic force applied to the sagged pipeline with the length corresponding to the critical, coincides with the frequency of natural vibrations. It is found that the loss of stability of submerged pipelines occurs in the resonant region of the pipeline vibration due to the increased variable hydrodynamic force.

The remoteness of the construction site from the production base, large volumes of work, insufficient productivity of asphalt concrete plants for the preparation of hot asphalt concrete mixtures makes urgent the use of cold bitumen concrete mixes for the road construction. The preliminary mix preparation on the production sites with preservation of its properties for several months allows to increase the duration of the construction season. Purpose. Quality improvement of construction of non-rigid road surfaces using cold bitumen concrete mixes. Materials and methods. Models of road pavement structure based on cold bitumen concrete mixes are proposed to clarify the influence of the structural, climatic, technological and thermophysical properties of materials on the pavement quality. Research results. It is shown that the construction of road surfaces using cold bitumen concrete mixes even at positive ambient temperatures, does not provide the required surface quality. Conclusions. To improve the road paving quality using cold bitumen concrete mixes is necessary to heat the base before laying the cold mix. The heating temperature of the base depends on the layer thickness and ambient temperature.
