The types of Autonomous stationary energy-cooling systems designed for complete isolation of special objects operating without connection with the atmosphere are Considered. A technical solution is proposed that allows increasing the efficiency of the energy-cooling system, reducing the consumption of process water due to its partial recirculation for cooling the engine of an Autonomous power plant, as well as increasing the period of complete isolation of the object.

This article discusses the possibility of managing environmental and economic risks of investment projects. Environmental efficiency is an important indicator in assessing the effectiveness of an investment project. It is revealed that when assessing the environmental efficiency of an investment project, it is necessary to use the established standards and agreements, normative legal acts in the field of environmental law. However, the legislation in the Russian Federation in the field of environmental risk assessment requires accurate calculations that will facilitate the task of the investor in the field of adoption of an effective investment project. It is analyzed that the final decision on the implementation of the project depends on the quality of the assessment.

" During a long interruption of construction and installation works, as well as under the influence of the external environment on the unfinished construction of building structures, they are subject to a change in their properties and strength characteristics. To solve all problems, it is necessary to conduct a forensic examination in order to identify defects and assess the state of building structures and make decisions on the possibility and feasibility of completing construction work"

The article presents theoretical studies of the effect of various plasticizers on the mechanical properties of epoxy compositions. Based on this, the method of plasticization of the epoxy polymer ED-22 was chosen using the introduction of modified epoxy resin UP-563, which differs from the previously used modified compositions for repairing automotive vehicles in the field the simplicity of the availability of modifications in the field and as providing the widest range of changes in the properties of the epoxy composition for USAGE field. The scientific novelty lies in the justification for the creation of a new repair composition consisting of ED-22 epoxy-diane resin modified by UP-563 laproxil for the repair of hull and capacitive parts of automotive equipment in the field, which has increased vibration resistance. frost resistance and impact resistance.

The paper proposes to perform quality control of the production work on the consolidation of soil foundation with the use of the method. Application of geo-radiolocation sensing allows to specify and complement the results of engineering and geological surveys, as well as capture the changes taking place in the grounds of foundations after work on fixing them. This will provide a comprehensive picture of the grouting in the underlying foundation of the building and provide a reliable and simple quality control work.

The establishment of automated air monitoring systems is a promising way of the air monitoring devices development. The comparative analysis of literature has shown that thin films based on semiconductor metal oxides are effective and widely used material for air monitoring systems creation. In order to create effective and more sensitive sensors it is important to research processes that occur on the surface of the gas sensitive material when it contacts with different substances. The processes that proceed on the surface of gas sensitive material based on SiO2SnOxCuOy during the interaction with molecules of nitrogen dioxide. Quantum chemical calculations have shown that there are three possible mechanisms of interaction between the molecules of nitrogen dioxide with a surface of gas sensitive material.

The problem of air quality control is relevant at the present time. There are a lot of different devices and methods of air monitoring. The promising devices for air monitoring are automated air monitoring systems functioning in real time regime. The basic part of such system is a chemical gas sensor. Gas sensors can be combined into the arrays or so called multisensory systems to increase their effectiveness. Sensor arrays using semiconductor sensors based on SiO2CuOx, SiO2SnOxCuOy, SnOxZrOy, silver-polyacrylonitrile thin films made at department of chemistry and ecology have been investigated in this work. As a result of sensors signals processing gas recognition technique has been developed. The recognition of ammonia, nitrogen dioxide, chlorine has been made.
