The article considers the influence of the technical condition of buildings on their additional deformations in the zone of influence of new construction. As a result of the survey, it was confirmed that the buildings of the historical development of the III category of technical condition were in an unsatisfactory condition. In accordance with this, a numerical calculation was carried out, as a result of which an option for strengthening their foundations with the help of piles made using jet technology was proposed. According to the preliminary numerical calculation, additional deformations of buildings of the III category did not exceed the maximum permissible values. The adopted option of strengthening in this case did not justify itself and the actual deformations of the buildings turned out to be higher than the limit values ​​already at the zero mark. Based on the monitoring data, it was found that the values ​​of additional settlements are constantly growing in the process of erecting buildings of the multifunctional complex. Based on the calculation data, graphs were constructed illustrating the discrepancy between the actual additional deformations and the calculated values ​​depending on the category of the technical condition of the buildings and their location in the zone of influence of the pit. Thus, when determining the zone of influence of new construction in close proximity to historical buildings, it is necessary to take into account their technical condition and operational safety.

In the article the attempt to understand the impact of human capital externalities in the process of development of the city. Within the economic area of ​​the city can appear human capital externalities associated with the "overflow" of knowledge and network effects that can be determinants of intensification of innovation - infrastructure elements of modern urban environment and, consequently, the factors of economic growth and economic system of the state as a whole. Author's concept of ways to improve the urban environment, taking into account the externalities of human capital.

In this article is reviewed the nature of organic hybrid nanocomposites. Promising directions in the field of organic hybrid nanocomposite materials will be methods for the synthesis of multicomponent materials, as well as the type of "net net" and "host-guest". The fundamental problem with the chemistry and physics of nanocomposites is dependent "structure-property". Solving this problem will move from research materials to their purposeful design.

Keywords: nanocomposite sol-gel technology, synthesis, nanoparticles.
