The Impact

The article considers negative trends in demographic processes associated with the impact of the environment on the life and health of the Krasnoyarsk city population. Methodological features of the study of the research subject are discussed, as well as the elaboration of the problem within the framework of specific sciences is analyzed. To what extent does the habitat with an increased level of technogenic pollution affect the subjective attitudes of residents, their needs, opinions, plans, and decision-making regarding demographic aspects of life? The presented results of expert interviews with specialists in the field of environmental protection and public health were taken by the author in November 2020. They indicate a truly deplorable situation in one of the major industrialized cities of Russia, Krasnoyarsk. The main pollutants are supposed to be transport, the RUSAL aluminum plant, the private sector with coal-fired heating and three coal-fired power plants. The Krasnoyarsk hydroelectric power station has a negative impact as well. The experts point to the obvious insufficiency of studying the problem of the impact on the demographic indicators and behavior of citizens, which is associated with the lack of open information about the level of the Krasnoyarsk urban environment pollution and specialized research in this direction.

Urgency of the research. Current trends of distributed generation development in Ukraine indicate a rapid generation in-crease from renewable energy plants. Most developed countries gradually refuse from the fossil fuels use and invest more and more to the “green” energy. Therefore, there is a need for a detailed study of the operation conditions of distributed energy sources due to their instability, as well as the processes that arise in distribution electric networks with diverse types of distributed energy sources. Target setting. In the producing process of power energy by distributed energy sources due to the increase in their num-ber, there are situations where several renewable sources of energy operate to only one system of buses. Thus, such distributive networks acquire the features of a local power system, which complicates the control process of such systems, and also there is a problem with the electricity supply of consumers. Actual scientific researches and issues analysis. The analysis of publications suggests that in literature more attention is paid to studying the operating modes of solar power plants, or small hydroelectric power plants. However, almost no attention was paid to the study of their cooperation work. Uninvestigated parts of general matters defining. Only a few works are devoted to the study of the cooperation of the diverce sources of distributed energy sources in the local electrical systems. That is why, their impact on power distribution networks and on the grid in general has not been studied extensively. The research objective. In this article was considered the influence of asynchronous generators on small hydroelectric power plants on the operation modes of distribution electrical networks, and were investigated the processes that are occurring in local power systems with different types of distributed energy sources. The statement of basic materials. Based on the research results, was developed a computer model of a such system in the PS CAD software environment. Two solar stations and one small hydroelectric power station with an asynchronous generator were connected to the power supply. It was shown the simulation of two modes of operation: a joint operation of a small hydroelectric power station, two solar power stations and a power supply center; a joint operation of a small hydroelectric pow-er plant, two solar power stations and a power supply disconnected. Conclusions. As a result of computer simulation, it is shown that by switching on a small hydroelectric power plant with an asynchronous generator in the case of an emergency shutdown of centralized power supply, it is possible to restore the work of solar power plants, and thus partially or completely restore the power supply of consumers.

The experience of operation of surface emergency gates in ice-breaking conditions at a number of hydroelectric power plants has shown the insuffi cient eff ectiveness of the methods used to combat freezing of structures. The rules for technical operation of spillway dam gates in winter provide for heating of structures by slots, threshold and skin in conjunction with measures to maintain mines before construction. However, measures to heat gates and build mines are not always suffi ciently justifi ed and justifi ed. In order to obtain full-scale data and scientifi c information for the development of recommendations on operating and accounting modes during design, full-scale studies of stresses and defl ections in the load-bearing elements of the watershed gate of the hydroelectric power station were carried out. This article presents the results of fi eld studies in comparison with calculated values. As a result of the studies, information on the static operation of fl at gates in winter conditions is obtained, which is of theoretical and practical interest. The materials can be used to clarify technical operation rules and to clarify regulatory documents for the design of hydromechanical equipment at hydroelectric power stations.

Family is an important institution to build a person's personality, morality, value and attitude. When this institution communicates properly, it shows the impact e.g. a boy or a girl becomes social human being. Unfortunately in our family gender biasness is reinforced continuously by starting to behave differently with boys and girls from the childhood. Parents communicate with them in a different way which constructs the traits of “masculinity” and “femininity”. Girls are compelled to learn the feminine role with politeness, submissiveness and their mobility is restricted in public world. It is a family which trains a girl to be a good mother, wife, sister or daughter, on the other hand a boy learns to be social, intellectual, able to run the world and strong. This different formation of role and behavior results in the ongoing discrimination everywhere in the society. This reinforcement is sort of relief from social stigmatization but has overall negative impact on life and through this family can be counted as the main birthplace of discrimination against women. Girls and boys must be raised neutrally to eradicate the gender differences and ensure the equality.

Controlling the system—the environment of power plants is called such a transformation—their material, energy and information inputs in time, which will ensure that the purpose of the operation of this system or the state of the environment, is achieved. The transformations of systems and environmental inputs and their goals describe the different models, e.g., LCA model groups and methods. When converting wind kinetic energy into electricity, wind power plants emit literally no harmful substances into the environment. However, the production and postuse management stages of their components require large amounts of energy and materials. The biggest controlling problem during postuse management is wind power plant blades, followed by waste generated during their production. Therefore, this publication is aimed at carrying out an ecological, technical and energetical transformation analysis of selected postproduction waste of wind power plant blades based on the LCA models and methods. The research object of control was eight different types of postproduction waste (fiberglass mat, roving fabric, resin discs, distribution hoses, spiral hoses with resin, vacuum bag film, infusion materials residues, surplus mater), mainly made of polymer materials, making it difficult for postuse management and dangerous for the environment. Three groups of models and methods were used: Eco-indicator 99, IPCC and CED. The impact of analysis objects on human health, ecosystem quality and resources was controlled and assessed. Of all the tested waste, the life cycle of resin discs made of epoxy resin was characterized by the highest level of harmful technology impact on the environment and the highest energy consumption. Postuse control and management in the form of recycling would reduce the negative impact on the environment of the tested waste (in the perspective of their entire life cycle). Based on the results obtained, guidelines and models for the proecological postuse control of postproduction polymer waste of wind power plants blades were proposed.

Energy Supply Systems

The current technological infrastructure in the electricity, heat, cold, and gas supply, as a rule, is formed and controlled separately by local systems and tasks. The traditionally considered energy systems unite large energy sources, such as hydroelectric power station, combined heat and power plants, boiler plants, and electric and pipeline networks distributed over a large area. New trends in the energy sector necessitate a revision of the principles of construction of energy systems and the creation of integrated energy supply systems. Combining separate different types of systems of different levels into a single integrated system with many coordinated elements can contribute to the implementation of new functionality, the use of more advanced technologies in operation and the active participation of consumers with distributed generation in the energy supply process. For the study of integrated energy supply systems it is proposed to use a multiagent approach, which is one of the promising areas of research for complex systems. This approach is used in many subject areas to study systems that include many elements with complex behavior. Such systems include integrated energy supply systems. The solution of the problem on the basis of the agent approach is developed by a multitude of interrelated agents.

The Impact

Extensive research of the variability of flows under the impact of climate change has been conducted for the Upper Indus Basin (UIB). However, limited literature is available on the spatial distribution and trends of suspended sediment concentrations (SSC) in the sub-basins of UIB. This study covers the comparative assessment of flows and SSC trends measured at 13 stations in the UIB along with the variability of precipitation and temperatures possibly due to climate change for the past three decades. In the course of this period, the country’s largest reservoir, Tarbela, on the Indus River was depleted rapidly due to heavy sediment influx from the UIB. Sediment management of existing storage and future planned hydraulic structures (to tap 30,000 MW in the region) depends on the correct assessment of SSC, their variation patterns, and trends. In this study, the SSC trends are determined along with trends of discharges, precipitation, and temperatures using the non-parametric Mann–Kendall test and Sen’s slope estimator. The results reveal that the annual flows and SSC are in a balanced state for the Indus River at Besham Qila, whereas the SSC are significantly reduced ranging from 18.56%–28.20% per decade in the rivers of Gilgit at Alam Bridge, Indus at Kachura, and Brandu at Daggar. The SSC significantly increase ranging from 20.08%–40.72% per decade in the winter together with a significant increase of average air temperature. During summers, the SSC are decreased significantly ranging from 18.63%–27.79% per decade along with flows in the Hindukush and Western–Karakorum regions, which is partly due to the Karakorum climate anomaly, and in rainfall-dominated basins due to rainfall reduction. In Himalayan regions, the SSC are generally increased slightly during summers. These findings will be helpful for understanding the sediment trends associated with flow, precipitation, and temperature variations, and may be used for the operational management of current reservoirs and the design of several hydroelectric power plants that are planned for construction in the UIB.

This paper discusses the current state of the avifauna on the territory of the Krasnoyarsk Reservoir. To date, the species composition of birds in the study area has not been studied, although it is worth noting the need to study the distribution of birds in this area. The construction of the Krasnoyarsk hydroelectric power station led to changes in the hydrological regime of the Yenisei River with subsequent flooding of the surrounding territory, as a result of which various geological processes of collapse of the Krasnoyarsk Reservoir banks are observed. Bank metamorphoses can also influence the spatial distribution of birds and creation of new ornithocomplexes. Our ecological and faunal analysis was carried out over two years (20182019) at nine key points along the bank lines of the Krasnoyarsk Reservoir within a radius of one kilometer from the water to identify the impact of geological changes in the banks on the nature of bird placement. The key areas of the study were determined, taking into account various biotopic habitat conditions that attract birds. Monitoring of avifauna on the territory of the Krasnoyarsk Reservoir will allow us to assess the degree of influence of changes in the geological processes of the banks on the spatial and biotopic distribution of birds, and it is also possible to forecast the disappearance or movement of some species and subspecies on this territory.

ulfates are the dominant ions among the major ones in the Amur region’s sewage. Therefore, the purpose of the research is to study the long-term dynamics of the content and runoff of sulfates in the Amur River in the winter low-water, based on the materials of Roshydromet for 1943-1976 and the author’s data for 1999-2019.Significant variations in the main areas were found due to both the diversity of natural conditions and anthropogenic influence in the areas of large cities and localities. The impact of the construction of hydroelectric power plants, significant economic changes in the Chinese part of the Amur basin, as well as the closure of pulp and paper and microbiological industries in the Russian part of the Amur basin on the long-term dynamics of the content and flow of sulfates is estimated. The maximum content of sulfates in the Amur River was observed after the accident at the Jilin chemical plant in China in December 2005. The influence of major floods on the increase in the flow of sulphates in the winter low-water was established.
