Research data keyboard_double_arrow_right Dataset 2015Publisher:Theoretical and Applied Ecology Authors: E. V. Yakovleva; D. N. Gabov; V. A. Beznosikov; B. M. Kondratenok;The purpose of the present work was accessing the influence of benz[a]pyrene added into substrate on composition of polyarenes in plant and on growth and development of common barley (Hordeum vulgare) in in vitro conditions. We found that contamination of substrate with benz[a]pyrene (BP) decreased seed germination of Hordeum vulgare L. Larger BP doses produced the trend for a linear decrease in height and biomass of the aboveground part of Hordeum vulgare. The change of root biomass is not linear. Using the method of highly-efficient liquid chromatography, we identified 14 structures of polyaromatic hydrocarbons (PAHs). Significant amounts of light polyarenes were found in the control plants. Concentration of polyarenes in the plants grown on polluted substrate varied depending on benz[a]pyrene doses. The pollutant in doses of 10–20 ng/g increased content of polyarenes in the plants. The dose of 30 ng/g started the mechanisms of polyarene decomposition and so concentration decreased. Higher doses disturbed the protection mechanisms of plants and so increased content of polyarenes in plants and decreased biomass. Light polyarenes preferably accumulated in aboveground plant part whereby heavy polyarenes – in roots.

Almost 75 percentage of the population lives in rural areas and only about 30 percentage of the rural households have access to grid electricity and about 42 percentage of the population no access to the electricity. It is highly difficult to extend high tension transmission lines to these areas as some of the places are separated from the mainland and from each other by wide rivers, creeks and hills. Renewable energy is considered to be the right choice for providing clean energy to these remotesettlements. Off-Grid energy systems are growing in popularity as an independent source of energy to satisfy electricity needs of individual households, small communities and commercial applications. Mainly in Bangladesh where the main grid is either not developed or the grid is noncommercial to extend due to remoteness of the location. A successfully installed Off-Grid energy system for several years to provide a reliable 24-h electricity supply to the inhabitant of an island. The objective of this paper is to analyze and design an off-grid energy system for Bangladesh consisting of PV panels, charge controller, battery and inverter to serve a remote locality. A mini solar grid of 21KWh capacity has been designed.

Lemeshko; Sherzod K. Khaldarov;Relevance. The power provided by generating stations based on wind and solar energy depends on the state of the environment at a particular geographical point, the prevailing wind speeds and the level of solar insolation. The wind speeds and solar insolation characterizing patterns are probabilistic in nature and depend on the terrain and season. This means that the power provided by generating stations based on renewable energy sources is also probabilistic. Risks associated with an inaccurate knowledge of the probabilistic patterns describing renewable energy sources, as well as the unpredictability (uncertainty) of the natural environment affecting renewable energy sources, are the reasons why system operators do not take into account such stations in calculating the power balance. This situation does not allow considering the generating stations as full-fledged market participants, covering the flow of investments in such projects. Accurate determination of the output power distribution laws for solar and wind power stations, based on the wind speed and solar insolation data analysis can significantly help system operators in power predicting of the power stations. Aim of study is building models of distribution laws that best describe the results of wind speed and solar insolation observations, as well as models of distribution laws for the generated power of wind and solar stations. Methods: methods for estimating the parameters of distribution laws, methods for testing statistical hypotheses. Results. It is shown, that the 3rd kind of beta distribution laws and their mixtures describe the series of measured wind speed and solar insolation better in the territory. The same concerning the probability distribution of the wind and solar stations power. Distribution law models for wind speed, solar insolation and power of the corresponding stations are constructed. It is shown that on the basis of the law of the distribution of wind speed and the mathematical relationships that connect power with wind speed, good models can be constructed for the probability distributions of power of wind power stations. The models can be used as an auxiliary tool for power system operators to predict output power.

In addition to solar energy, wind energy can be used in the region. Since agriculture is the major branch of the economy in the Republic, waste from it can be used as biogas. This paper discusses the use of renewable energy sources in protected areas where additional noise devices and aggregates cannot be used. Also, the use of high-voltage power lines can lead to fires, and they occupy part of the useful area of nature reserves, so additional maintenance is required. To solve this problem, we analyzed the current state of the reserve for the protection of saiga lands in Kalmykia. The questions of insolation depending on the seasons and day-night characteristics are also investigated. The materials were the results of expedition routes conducted in recent years in the Black Lands reserve, data from cordons. The obtained materials will make it possible to use non-traditional types of energy for lighting cordons, hunting and tourist areas, in particular, the use of solar modules of different designs. To promote specially protected areas and the use of solar energy.

This work is devoted to the development of the concept of energy supply for an individual house with zero energy consumption, taking into account the climatic indicators of the construction area. The research set the following goals: 1. Systematization and analysis of existing research in the field of energy efficient housing construction. 2. Assessment of renewable energy sources such as solar, wind, air and geothermal energy. 3. Development of a procedure for selecting an efficient power supply system for a passive house. 4. Checking the algorithm for selecting an efficient power supply system for a passive house in Russia. 5. Determination of economic indicators of the energy supply system of an individual house with zero energy consumption for each of the three selected regions. After analyzing the existing concepts of energy efficient houses and the use of renewable energy sources in Russia, it was decided to propose such a concept for the energy supply of a passive house, which includes the combined work of a geothermal pump and solar panels. Based on the evaluation of the efficiency of solar and geothermal energy, an algorithm for selecting an efficient energy supply system for a house with zero energy consumption was developed. Next, the algorithm for selecting an efficient power supply system for a passive house was tested for three selected regions located in Russia. With the Photovoltaic geographical information system website, three cities were selected where it is most optimal to install solar panels: Vladivostok, Irkutsk and Petropavlovsk-Kamchatsky. For private houses with a heated area of 90 m2, located in Vladivostok, Irkutsk and Petropavlovsk-Kamchatsky, a geothermal and solar installation was selected, and the cost of this equipment and its payback period were calculated. In addition, the economically optimal number of solar panels for the three cities under consideration was determined.

The Asia-Pacific region and the countries of Southeast Asia, in the medium term, will become a key center in world oil refining, which is associated with high rates of economic growth, population growth and the fleet of vehicles in the countries of the region. Under the influence of the main trends in the development of the world oil market, as well as due to the policies of developed countries aimed at the application of environmental and energy-efficient technologies, the structure of production of oil products in the world is gradually changing. So, in this regard, the demand for light and medium distillates and LNG is growing in the Asia-Pacific countries, and the demand for heavy is falling. According to experts, gas demand will grow faster than oil. The key drivers of this growth are environmental friendliness and low cost in comparison to other fossil fuels. In Asia and the Middle East, gas generation will replace coal and oil, respectively. Gas consumption will grow, another driver of the growth of generating gas capacities is the fears of many countries about the safety and reliability of the nuclear power industry. In addition to the electric power industry, due to population growth, gas consumption in the housing sector and industry will increase. The Middle East, the only major producer of low-cost oil, will remain the center of global oil production in the long run. Неравномерность производства и потребления нефти в мировой экономике продолжает нарастать, спрос и предложение на продукцию всё более смещается в развивающиеся страны. Азиатско-Тихоокеанский регион и страны Юго-Восточной Азии, в среднесрочной перспективе, станут ключевым центром в мировой нефтепереработке, что связано с высокими темпами роста экономики, прироста населения и парка транспортных средств в странах региона. Под влиянием основных тенденций развития мирового рынка нефти, а также вследствие политики развитых стран, направленных на применение экологических и энергоэффективных технологий, структура производства потребления продукции нефтепереработки в мире постепенно изменяется. Так, в связи с этим в странах АТР растёт спрос на легкие и средние дистилляты и СПГ, а спрос на тяжелые падает. По оценкам экспертов спрос на газ будет расти быстрее, чем на нефть. Ключевыми факторами этого роста стали экологичность и низкая стоимость относительно других ископаемых видов топлива. В Азии и на Ближнем Востоке газовая генерация будет заменять угольную и нефтяную соответственно. Потребление газа будет расти, еще один драйвер роста генерирующих газовых мощностей - опасения многих стран по поводу безопасности и надежности атомной электроэнергетики. Помимо электроэнергетики, в связи с ростом населения будут расти объемы потребления газа в секторе ЖКХ и промышленности. Ближний Восток, единственный крупный производитель недорогой нефти, в долгосрочной перспективе останется центром мировой нефтедобычи ВОПРОСЫ СТРУКТУРИЗАЦИИ ЭКОНОМИКИ, Выпуск 4 (79) 2020, Pages 102-106

Research data keyboard_double_arrow_right Dataset 2015Publisher:Theoretical and Applied Ecology Authors: E. V. Yakovleva; D. N. Gabov; V. A. Beznosikov; B. M. Kondratenok;The purpose of the present work was accessing the influence of benz[a]pyrene added into substrate on composition of polyarenes in plant and on growth and development of common barley (Hordeum vulgare) in in vitro conditions. We found that contamination of substrate with benz[a]pyrene (BP) decreased seed germination of Hordeum vulgare L. Larger BP doses produced the trend for a linear decrease in height and biomass of the aboveground part of Hordeum vulgare. The change of root biomass is not linear. Using the method of highly-efficient liquid chromatography, we identified 14 structures of polyaromatic hydrocarbons (PAHs). Significant amounts of light polyarenes were found in the control plants. Concentration of polyarenes in the plants grown on polluted substrate varied depending on benz[a]pyrene doses. The pollutant in doses of 10–20 ng/g increased content of polyarenes in the plants. The dose of 30 ng/g started the mechanisms of polyarene decomposition and so concentration decreased. Higher doses disturbed the protection mechanisms of plants and so increased content of polyarenes in plants and decreased biomass. Light polyarenes preferably accumulated in aboveground plant part whereby heavy polyarenes – in roots.

Almost 75 percentage of the population lives in rural areas and only about 30 percentage of the rural households have access to grid electricity and about 42 percentage of the population no access to the electricity. It is highly difficult to extend high tension transmission lines to these areas as some of the places are separated from the mainland and from each other by wide rivers, creeks and hills. Renewable energy is considered to be the right choice for providing clean energy to these remotesettlements. Off-Grid energy systems are growing in popularity as an independent source of energy to satisfy electricity needs of individual households, small communities and commercial applications. Mainly in Bangladesh where the main grid is either not developed or the grid is noncommercial to extend due to remoteness of the location. A successfully installed Off-Grid energy system for several years to provide a reliable 24-h electricity supply to the inhabitant of an island. The objective of this paper is to analyze and design an off-grid energy system for Bangladesh consisting of PV panels, charge controller, battery and inverter to serve a remote locality. A mini solar grid of 21KWh capacity has been designed.

Lemeshko; Sherzod K. Khaldarov;Relevance. The power provided by generating stations based on wind and solar energy depends on the state of the environment at a particular geographical point, the prevailing wind speeds and the level of solar insolation. The wind speeds and solar insolation characterizing patterns are probabilistic in nature and depend on the terrain and season. This means that the power provided by generating stations based on renewable energy sources is also probabilistic. Risks associated with an inaccurate knowledge of the probabilistic patterns describing renewable energy sources, as well as the unpredictability (uncertainty) of the natural environment affecting renewable energy sources, are the reasons why system operators do not take into account such stations in calculating the power balance. This situation does not allow considering the generating stations as full-fledged market participants, covering the flow of investments in such projects. Accurate determination of the output power distribution laws for solar and wind power stations, based on the wind speed and solar insolation data analysis can significantly help system operators in power predicting of the power stations. Aim of study is building models of distribution laws that best describe the results of wind speed and solar insolation observations, as well as models of distribution laws for the generated power of wind and solar stations. Methods: methods for estimating the parameters of distribution laws, methods for testing statistical hypotheses. Results. It is shown, that the 3rd kind of beta distribution laws and their mixtures describe the series of measured wind speed and solar insolation better in the territory. The same concerning the probability distribution of the wind and solar stations power. Distribution law models for wind speed, solar insolation and power of the corresponding stations are constructed. It is shown that on the basis of the law of the distribution of wind speed and the mathematical relationships that connect power with wind speed, good models can be constructed for the probability distributions of power of wind power stations. The models can be used as an auxiliary tool for power system operators to predict output power.

In addition to solar energy, wind energy can be used in the region. Since agriculture is the major branch of the economy in the Republic, waste from it can be used as biogas. This paper discusses the use of renewable energy sources in protected areas where additional noise devices and aggregates cannot be used. Also, the use of high-voltage power lines can lead to fires, and they occupy part of the useful area of nature reserves, so additional maintenance is required. To solve this problem, we analyzed the current state of the reserve for the protection of saiga lands in Kalmykia. The questions of insolation depending on the seasons and day-night characteristics are also investigated. The materials were the results of expedition routes conducted in recent years in the Black Lands reserve, data from cordons. The obtained materials will make it possible to use non-traditional types of energy for lighting cordons, hunting and tourist areas, in particular, the use of solar modules of different designs. To promote specially protected areas and the use of solar energy.

This work is devoted to the development of the concept of energy supply for an individual house with zero energy consumption, taking into account the climatic indicators of the construction area. The research set the following goals: 1. Systematization and analysis of existing research in the field of energy efficient housing construction. 2. Assessment of renewable energy sources such as solar, wind, air and geothermal energy. 3. Development of a procedure for selecting an efficient power supply system for a passive house. 4. Checking the algorithm for selecting an efficient power supply system for a passive house in Russia. 5. Determination of economic indicators of the energy supply system of an individual house with zero energy consumption for each of the three selected regions. After analyzing the existing concepts of energy efficient houses and the use of renewable energy sources in Russia, it was decided to propose such a concept for the energy supply of a passive house, which includes the combined work of a geothermal pump and solar panels. Based on the evaluation of the efficiency of solar and geothermal energy, an algorithm for selecting an efficient energy supply system for a house with zero energy consumption was developed. Next, the algorithm for selecting an efficient power supply system for a passive house was tested for three selected regions located in Russia. With the Photovoltaic geographical information system website, three cities were selected where it is most optimal to install solar panels: Vladivostok, Irkutsk and Petropavlovsk-Kamchatsky. For private houses with a heated area of 90 m2, located in Vladivostok, Irkutsk and Petropavlovsk-Kamchatsky, a geothermal and solar installation was selected, and the cost of this equipment and its payback period were calculated. In addition, the economically optimal number of solar panels for the three cities under consideration was determined.

The Asia-Pacific region and the countries of Southeast Asia, in the medium term, will become a key center in world oil refining, which is associated with high rates of economic growth, population growth and the fleet of vehicles in the countries of the region. Under the influence of the main trends in the development of the world oil market, as well as due to the policies of developed countries aimed at the application of environmental and energy-efficient technologies, the structure of production of oil products in the world is gradually changing. So, in this regard, the demand for light and medium distillates and LNG is growing in the Asia-Pacific countries, and the demand for heavy is falling. According to experts, gas demand will grow faster than oil. The key drivers of this growth are environmental friendliness and low cost in comparison to other fossil fuels. In Asia and the Middle East, gas generation will replace coal and oil, respectively. Gas consumption will grow, another driver of the growth of generating gas capacities is the fears of many countries about the safety and reliability of the nuclear power industry. In addition to the electric power industry, due to population growth, gas consumption in the housing sector and industry will increase. The Middle East, the only major producer of low-cost oil, will remain the center of global oil production in the long run. Неравномерность производства и потребления нефти в мировой экономике продолжает нарастать, спрос и предложение на продукцию всё более смещается в развивающиеся страны. Азиатско-Тихоокеанский регион и страны Юго-Восточной Азии, в среднесрочной перспективе, станут ключевым центром в мировой нефтепереработке, что связано с высокими темпами роста экономики, прироста населения и парка транспортных средств в странах региона. Под влиянием основных тенденций развития мирового рынка нефти, а также вследствие политики развитых стран, направленных на применение экологических и энергоэффективных технологий, структура производства потребления продукции нефтепереработки в мире постепенно изменяется. Так, в связи с этим в странах АТР растёт спрос на легкие и средние дистилляты и СПГ, а спрос на тяжелые падает. По оценкам экспертов спрос на газ будет расти быстрее, чем на нефть. Ключевыми факторами этого роста стали экологичность и низкая стоимость относительно других ископаемых видов топлива. В Азии и на Ближнем Востоке газовая генерация будет заменять угольную и нефтяную соответственно. Потребление газа будет расти, еще один драйвер роста генерирующих газовых мощностей - опасения многих стран по поводу безопасности и надежности атомной электроэнергетики. Помимо электроэнергетики, в связи с ростом населения будут расти объемы потребления газа в секторе ЖКХ и промышленности. Ближний Восток, единственный крупный производитель недорогой нефти, в долгосрочной перспективе останется центром мировой нефтедобычи ВОПРОСЫ СТРУКТУРИЗАЦИИ ЭКОНОМИКИ, Выпуск 4 (79) 2020, Pages 102-106
