The article deals with the issues of impact interaction of particles with layers of dispersed material of different thickness. The influence of the interaction velocity and the thickness of the substrate on the appearance and structure of the collision result is investigated. It is established that at low speeds there is a crater formation while the particle is on the substrate surface. With the growth of the interaction rate, the formation of a crown is observed, and particles penetrate into the substrate material. Experimentally determined the values of the velocity and thickness of the substrate, corresponding to the beginning of the formation of the crown.

The problems of young families are analyzed. The relevance of the study of the social welfare of modern young families is shown. A cognitive model of achievement and stabilization of the social welfare of a young family was constructed on the basis of the results of the study ""The Life of a Young Family in the Rostov Region"", 2017. It is shown that the basic model of achieving social well-being is a two-loop scheme with positive feedback. Each of the contours of which corresponds to the basic characteristics: socio-cultural and economic well-being. The principal problem of the factor of satisfaction of needs is revealed. The necessity of creating a full-fledged monitoring system of the socio-economic level of a young family included in the social policy framework of the state is shown.

Background: The quality of electricity is one of the main problems necessary for the normal functioning of responsible technological processes in which a slight distortion of the supply voltage can lead to a violation of the normal operation of enterprises. There are several solutions to this problem: uninterruptible power systems, fast automatic power reserve technology (FAPR), dynamic voltage distortion compensator (DVDC). The most interesting solution is the application of dynamic voltage distortion. Material and methods: The principles of constructing a dynamic voltage distortion compensator with multilevel voltage inverters are investigated. An imitation model constructed under the following assumptions is proposed: an ideal case of the main circuit system (without higher harmonics) is considered, the nonlinearity of the transformer is not taken into account, short-circuit currents are absent, only constant load power is used. Assumptions are justified by the fact that in practice their error is no more than 3-5%, which is permissible. The results are obtained by modeling the system in the MatLab 2016b package. Results: A fundamentally new structural and functional scheme of a dynamic voltage distortion compensator with a multilevel system is developed. The requirements for the dynamic compensator of voltage distortion, load, LC-filters, current-voltage transformers and a converter are determined. Simulation of the simulation model has shown that the system works and corresponds to the expected results. Conclusions: The proposed voltage compensation system will solve the problem of the normal functioning of technological processes. The simulation results showed that the declared functional of the DVDC provides compensation of the voltage level in a given range of voltage dips. The obtained results can be used to stabilize the power supply: in the power supply systems of medical institutions, electric transport, critical energy facilities of a high category.

Article considers the fundamentals of the organization of construction works in cramped conditions of the current town-planning situation, the impact of construction works on the environment, and a brief description of the negative impact factors is provided. The expediency of a systematic approach to improving the quality of construction is shown, including taking into account the assessment of the state of the environment and the need to reduce the negative impact of construction and installation works on nearby built-up areas. The necessity of taking into account measures to reduce the levels of negative impact on the environment during the project development of the production of works is substantiated, and a number of recommendations are given on the organization of construction works.

The article proposes some innovative technical solutions to build a multistory substructure for residential and public buildings. To erect a building, it is proposed to construct a system of interconnected rail runways at a first storey level along which travelling gantry cranes and special platforms will move. To descend the machines, building materials, instruments to the design level, during the underground space development, it is proposed to employ travelling gantry cranes. In order to quickly relocate loads and machines from one work zone to another, an additional system of rails is mounted along which special platforms are moving. The management of the gantry cranes and special platforms movement is done by the remote operating panels. The superstructure is built in the traditional way using a tower crane, track mounted, for example. The application of the proposed designs when building multistory substructures will enable to improve the technological processes of building the substructures. The proposed technology will help to use it in all the climatic areas of our country.
