Subject. The article updates the scientific view of the environmental protection greening and the special land use regime as a special city planning means of passive sanitary protection of people from the adverse aerial and technological impact and the recovery of the environment we live in. Objectives. I identify the specifics of designing and efficient operation of environmental protection greening as an inseparable part of the urban ecosystem. The article justifies the technique for strategic positioning of respective infrastructure projects in order to ensure the protective effect. Methods. The study relies upon general methods of analysis, systematization of existing viewpoints and published findings, graphic and logic analysis, matrix-based tools to choose an administrative strategy. Results. I analyzed the air-holding capacity of economic activity in regions and the outcome of air quality monitoring as a risk factor for public health. The article pinpoints operational difficulties in the environmental protection greening facilities and strategic approaches to addressing the issues in order to improve the environmental security of industrial zones. I determine new aspects of public relations and groups of criteria to assess the effectiveness of green infrastructure projects. The article provides the rationale for fiscal incentives for investors and public-private partnership of stakeholders. Conclusions and Relevance. Considering national projects, such as Ecology, Demography, Convenient Urban Environment, I emphasize the relevance of recovering and rehabilitating obsolete environmental protection greening facilities situated in industrial zones of industrially developed cities. Green projects should indeed comply with a set of progressive results of fundamental studies carried in various scientific areas. There should be fiscal incentives in terms of taxes and depreciation on special assets as the basis for the private-municipal partnership in green assets management in order to enhance the environmental security of industrial zones.

Working capital management refers to a company's managerial accounting strategy designed to monitor and utilize the two components of working capital, current assets and current liabilities, to ensure the most financially efficient operation of the company. The goal of working capital management is to manage the firm’s current asset and current liabilities in such a way that satisfactory level of working capital is maintained. A study on comparison in working capital management with State Bank of India and Industrial Credit and Investment Corporation of India is analyzed to know the liquidity and current ratio. The interaction between current asset and current liabilities is therefore is the main theme of the theory of working capital management.

There are investigated the influence of operating pressures in the gas supply system on the level of such energy indicators as efficiency, gas flow and gas overrun by gas equipment in residential buildings. There is established a relationship between the values of operating pressures in the gas supply system and the gas consumption level of household appliances. The causes of insufficient pressure in the gas networks of settlements are analyzed in the article. There is also developed an algorithm for calculating the change in the efficiency of gas appliances depending on the operational parameters of the gas network. It has been found that the most efficient operation of gas appliances is observed at an overpressure at the inlet of gas appliances of about 1200 Pa.To ensure the required quality of natural gas combustion among consumers and minimize gas consumption there are justified the following measures in the article: coordinating a domestic regulatory framework for assessing the quality of natural gas with international norms and standards; improving the preparation of gas coming from local wells before supplying it to gas distribution networks; auditing low pressure gas pipelines and reconstructing areas affected by corrosion; ensuring standard gas pressure in the network for the normal operation of domestic gas appliances; stating quality indicators of natural gas combustion by gas sales organizations.

This article studies the implementation of some well-known principles of information work of biological systems in the input unit of the neuroprocessor, including spike coding of information used in models of neural networks of the latest generation.<br> The development of modern neural network IT gives rise to a number of urgent tasks at the junction of several scientific disciplines. One of them is to create a hardware platform&nbsp;— a neuroprocessor for energy-efficient operation of neural networks. Recently, the development of nanotechnology of the main units of the neuroprocessor relies on combined memristor super-large logical and storage matrices. The matrix topology is built on the principle of maximum integration of programmable links between nodes. This article describes a method for implementing biomorphic neural functionality based on programmable links of a highly integrated 3D logic matrix.<br> This paper focuses on the problem of achieving energy efficiency of the hardware used to model neural networks. The main part analyzes the known facts of the principles of information transfer and processing in biological systems from the point of view of their implementation in the input unit of the neuroprocessor. The author deals with the scheme of an electronic neuron implemented based on elements of a 3D logical matrix. A pulsed method of encoding input information is presented, which most realistically reflects the principle of operation of a sensory biological neural system. The model of an electronic neuron for selecting ranges of technological parameters in a real 3D logic matrix scheme is analyzed. The implementation of disjunctively normal forms is shown, using the logic function in the input unit of a neuroprocessor as an example. The results of modeling fragments of electric circuits with memristors of a 3D logical matrix in programming mode are presented.<br> The author concludes that biomorphic pulse coding of standard digital signals allows achieving a high degree of energy efficiency of the logic elements of the neuroprocessor by reducing the number of valve operations. Energy efficiency makes it possible to overcome the thermal limitation of the scalable technology of three-dimensional layout of elements in memristor crossbars.
