Такое стремление особенно четко прослеживается в странах западной Европы. Это связано с высокой стоимостью зерновых ресурсов, что непосредственно влияет на конечную стоимость сельскохозяйственной продукции. Затраты на кормление в отдельных случаях могут составлять до 80% от конечной цены реализации продукции. Поэтому совершенствование технологий производства комбикормов и рационов питания сельскохозяйственных животных является актуальной задачей. В качестве заменителей зернового сырья могут выступать такие отходы промышленности как: свекольный жом, стебли бобовых, лузга различных зерновых культур и другие. Обычно заменители зернового сырья содержат в своём составе большую долю клетчатки и лигнина, которые сложно перевариваются в процессе пищеварения у сельскохозяйственных животных. Для более полного усвоения этих веществ необходимо проводить технологические операции, направленные на разрушение высокобиополимерных структур с целью получения более простых легкоусвояемых веществ. В статье рассматривается совершенствование технологии получения экструдированных комбикормов и кормовых добавок за счёт применения операции двухстадийного измельчения с химической обработкой и заморозкой сырья. When making mixed fodders, producers try to replace grain raw materials with various wastes of food and agro-industrial complex. Such aspiration is especially clear in the countries of Western Europe. This is due to the high cost of grain resources, which directly affects the final cost of agricultural products. Feeding costs in some cases can be up to 80% of the final selling price of products. Therefore, improvement of technologies of production of mixed fodders and diets for farm animals is an urgent task. As substitutes for grain, raw materials can be such industrial wastes as: beet pulp, stems of legumes, husks of various grain crops and others. Usually substitutes for grain raw materials contain a large proportion of fibre and lignin, which are difficult to digest during digestion in farm animals. For more complete assimilation of these substances it is necessary to carry out technological operations aimed at destruction of high biopolymer structures in order to obtain simpler easily digestible substances. The article examines the improvement of the technology of extruded mixed fodders and feed additives through the use of two-stage grinding operation with chemical treatment and freezing of raw materials.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2021Publisher:Zenodo Authors: Galina, Bityaeva; Mergen, Sangadzhiev;The Republic of Kalmykia is rich in solar energy, where the sun shines for more than three-quarters of a year. 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.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2024Publisher:ООО Цифра Изучение Мультинских озер Республики Алтай является сложной и многогранной задачей, требующей рассмотрения различных природных и антропогенных факторов, которые оказывают влияние на экосистему этих озер. Благодаря данным, собранным сотрудниками Катунского заповедника и представленным в летописях природы, мы можем ознакомиться с климатическими, гидрологическими и гидрохимическими особенностями данного региона, а также с их изменениями под воздействием человеческой деятельности. Климатические характеристики Мультинских озер играют важную роль в понимании экологической системы данного региона. Разнообразие климатических условий влияет на формирование и обновление водных ресурсов, а также на микроклиматические условия, которые существенно влияют на живые организмы в озерах и в окружающей их территории. Гидрологические и гидрохимические особенности Мультинских озер также являются неотъемлемой частью изучения их экосистемы. Данные о гидрологическом режиме, колебании уровня воды и температуре приземного слоя позволяют понять динамику круговорота воды, что влияет на живой мир в озерах и на прилегающую территорию. Гидрохимические данные позволяют определить уровень загрязнения воды тяжелыми металлами, минерализацию, насыщение воды кислородом и показатель pH. Эти данные очень важны, так как любые изменения в химическом составе могут быть связаны с антропогенным воздействием. Собранные данные также отражают изменения в экосистеме Мультинских озер под воздействием человеческой деятельности. Большое количество туристов может негативно влиять на заповедную территорию. Мониторинг данных позволяет выявить и оценить степень влияния туризма на экосистему озер и разработать меры по снижению негативного воздействия. The study of Multa Lakes of the Altai Republic is a complex and multifaceted task that requires consideration of various natural and anthropogenic factors that influence the ecosystem of these lakes. Thanks to the data collected by the staff of Katunsky Reserve and presented in nature chronicles, we can acquaint ourselves with climatic, hydrological and hydrochemical specifics of this region, as well as with their changes under the influence of human activity. Climatic characteristics of Multa Lakes play an important role in understanding the ecological system of this region. The diversity of climatic conditions influences the formation and renewal of water resources, as well as microclimatic conditions that significantly affect living organisms in the lakes and the surrounding area. Hydrological and hydrochemical features of Multa Lakes are also an integral part of the study of their ecosystem. Data on the hydrological regime, water level fluctuations and surface layer temperature allow to understand the dynamics of the water cycle, which affects the living world in the lakes and the surrounding area. Hydrochemical data can determine the level of heavy metal contamination, salinity, oxygen saturation and pH. These findings are very important as any changes in chemical composition can be linked to anthropogenic impacts. The data collected also reflects changes in the ecosystem of Multa Lakes under the influence of human activities. Numerous tourists can have a negative impact on the protected area. Data monitoring makes it possible to identify and evaluate the degree of tourism impact on the lakes' ecosystem and develop measures to reduce the negative impact.

Tikhonov; I.F. Reshetnikov;The aim of the article is a quantitative assessment of the influence of non-condensable gases on the intensity of heat and mass transfer processes during film condensation of steam in the specific conditions for heat exchanger. The task is achieved by conducting experimental research of heat and mass transfer processes in film condensation of steam in the presence of non-condensable gases.The study was carried out by the method of stationary heat flow on an experimental kettle with a jacket (0,02 m3 capacity), industrial cooking boilers (0,04 m3 and 0,06 m3 capacity). Cylindrical kettles with a hemispherical and elliptical bottom were selected as the condensation surface. The results of the experiments are presented in the form of a criterion equation for determining the mass transfer coefficient for vapor concentration diffusion. When the concentration of a non-condensable gas reaches 40% an intensification of the resulting heat transfer coefficient from the vapor-gas mixture to the condensation surface is observed. The coefficient of heat transfer to the condensation surface depends on the concentration of non-condensable gases in the apparatus cavity. The results of the research indicate that it is possible to improve the heat exchangers with a jacket and allow an assessment of the heat input when removing the gas mixture from the jacket in the heating mode of the cookers at the design stage. Material research allows to develop automatiс systems and control parameters in the operation of apparatus with a jacket

Kalinina; E. N. Demina;The purification of industrial and surface wastewater from heavy metal ions (HMI) to requirements for the discharge of treated wastewater into natural waters is one of the most complicated environmental and technological problems. For the deep purification of waste water from the HMI, the use of cheap sorbents obtained from production waste is the most promising. One of the many-tonnage wastes of technology of inorganic substances is the sludge formed in the production of soda by the ammonia Solvay, s method. Currently, sludge is stored in sludge accumulators and is a long-term source of pollution of environmental objects. Scientific developments in the utilization of slimes with the production of building materials, etc., have not found wide practical use, which is due to the heterogeneity of the granulometric and chemical composition of the waste. Carried out X-ray phase analysis and studies of the physicochemical and chemical properties of waste samples showed that its main components are calcium carbonate (calcite) and calcium hydroxide (portlandite). It is known that the natural mineral limestone efficiently extracts HMI from aqueous solutions with the formation of less soluble basic salts, carbonates, and hydroxy carbonates of HM. It has been established that sludge samples have high sorption activity when copper(II) and zinc ions are extracted from low concentrated solutions (sorption capacity for copper ions is 35.0 mg/g, sorption capacity for zinc ions is 40 mg/g). To increase the operational properties, a method has been developed for the production of a modified granular sorbent based on the sludge of soda production, consisting in treating with sodium silicate. The effect of a dose of sodium silicate in the sorbent composition on the mechanical strength and sorption properties of the obtained samples was studied. It has been established that the introduction of 8,6% SiO2 into the sludge leads to an increase in the mechanical strength by 50–80%, and does not have a significant effect on the sorption activity of the material. The kinetic and sorption regularities of extraction of copper(II) ions and zinc on modified sorbents are revealed. Based on the analysis of the adsorption isotherms obtained, the adsorption equilibrium constants and maximum adsorption values (Amax (Cu2+) = 50.8 mg/g; Amax (Zn2+) = 97.1 mg/g) were determined. Obtained sorption materials can be recommended for wastewater treatment from HMI.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2024Publisher:ООО Цифра При изготовлении комбикормов производители стремятся заменить зерновое сырьё различными отходами пищевого и агропромышленного комплекса. Такое стремление особенно четко прослеживается в странах западной Европы. Это связано с высокой стоимостью зерновых ресурсов, что непосредственно влияет на конечную стоимость сельскохозяйственной продукции. Затраты на кормление в отдельных случаях могут составлять до 80% от конечной цены реализации продукции. Поэтому совершенствование технологий производства комбикормов и рационов питания сельскохозяйственных животных является актуальной задачей. В качестве заменителей зернового сырья могут выступать такие отходы промышленности как: свекольный жом, стебли бобовых, лузга различных зерновых культур и другие. Обычно заменители зернового сырья содержат в своём составе большую долю клетчатки и лигнина, которые сложно перевариваются в процессе пищеварения у сельскохозяйственных животных. Для более полного усвоения этих веществ необходимо проводить технологические операции, направленные на разрушение высокобиополимерных структур с целью получения более простых легкоусвояемых веществ. В статье рассматривается совершенствование технологии получения экструдированных комбикормов и кормовых добавок за счёт применения операции двухстадийного измельчения с химической обработкой и заморозкой сырья. When making mixed fodders, producers try to replace grain raw materials with various wastes of food and agro-industrial complex. Such aspiration is especially clear in the countries of Western Europe. This is due to the high cost of grain resources, which directly affects the final cost of agricultural products. Feeding costs in some cases can be up to 80% of the final selling price of products. Therefore, improvement of technologies of production of mixed fodders and diets for farm animals is an urgent task. As substitutes for grain, raw materials can be such industrial wastes as: beet pulp, stems of legumes, husks of various grain crops and others. Usually substitutes for grain raw materials contain a large proportion of fibre and lignin, which are difficult to digest during digestion in farm animals. For more complete assimilation of these substances it is necessary to carry out technological operations aimed at destruction of high biopolymer structures in order to obtain simpler easily digestible substances. The article examines the improvement of the technology of extruded mixed fodders and feed additives through the use of two-stage grinding operation with chemical treatment and freezing of raw materials.

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.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2024Publisher:ООО Цифра Изучение Мультинских озер Республики Алтай является сложной и многогранной задачей, требующей рассмотрения различных природных и антропогенных факторов, которые оказывают влияние на экосистему этих озер. Благодаря данным, собранным сотрудниками Катунского заповедника и представленным в летописях природы, мы можем ознакомиться с климатическими, гидрологическими и гидрохимическими особенностями данного региона, а также с их изменениями под воздействием человеческой деятельности. Климатические характеристики Мультинских озер играют важную роль в понимании экологической системы данного региона. Разнообразие климатических условий влияет на формирование и обновление водных ресурсов, а также на микроклиматические условия, которые существенно влияют на живые организмы в озерах и в окружающей их территории. Гидрологические и гидрохимические особенности Мультинских озер также являются неотъемлемой частью изучения их экосистемы. Данные о гидрологическом режиме, колебании уровня воды и температуре приземного слоя позволяют понять динамику круговорота воды, что влияет на живой мир в озерах и на прилегающую территорию. Гидрохимические данные позволяют определить уровень загрязнения воды тяжелыми металлами, минерализацию, насыщение воды кислородом и показатель pH. Эти данные очень важны, так как любые изменения в химическом составе могут быть связаны с антропогенным воздействием. Собранные данные также отражают изменения в экосистеме Мультинских озер под воздействием человеческой деятельности. Большое количество туристов может негативно влиять на заповедную территорию. Мониторинг данных позволяет выявить и оценить степень влияния туризма на экосистему озер и разработать меры по снижению негативного воздействия. The study of Multa Lakes of the Altai Republic is a complex and multifaceted task that requires consideration of various natural and anthropogenic factors that influence the ecosystem of these lakes. Thanks to the data collected by the staff of Katunsky Reserve and presented in nature chronicles, we can acquaint ourselves with climatic, hydrological and hydrochemical specifics of this region, as well as with their changes under the influence of human activity. Climatic characteristics of Multa Lakes play an important role in understanding the ecological system of this region. The diversity of climatic conditions influences the formation and renewal of water resources, as well as microclimatic conditions that significantly affect living organisms in the lakes and the surrounding area. Hydrological and hydrochemical features of Multa Lakes are also an integral part of the study of their ecosystem. Data on the hydrological regime, water level fluctuations and surface layer temperature allow to understand the dynamics of the water cycle, which affects the living world in the lakes and the surrounding area. Hydrochemical data can determine the level of heavy metal contamination, salinity, oxygen saturation and pH. These findings are very important as any changes in chemical composition can be linked to anthropogenic impacts. The data collected also reflects changes in the ecosystem of Multa Lakes under the influence of human activities. Numerous tourists can have a negative impact on the protected area. Data monitoring makes it possible to identify and evaluate the degree of tourism impact on the lakes' ecosystem and develop measures to reduce the negative impact.

Tikhonov; I.F. Reshetnikov;The aim of the article is a quantitative assessment of the influence of non-condensable gases on the intensity of heat and mass transfer processes during film condensation of steam in the specific conditions for heat exchanger. The task is achieved by conducting experimental research of heat and mass transfer processes in film condensation of steam in the presence of non-condensable gases.The study was carried out by the method of stationary heat flow on an experimental kettle with a jacket (0,02 m3 capacity), industrial cooking boilers (0,04 m3 and 0,06 m3 capacity). Cylindrical kettles with a hemispherical and elliptical bottom were selected as the condensation surface. The results of the experiments are presented in the form of a criterion equation for determining the mass transfer coefficient for vapor concentration diffusion. When the concentration of a non-condensable gas reaches 40% an intensification of the resulting heat transfer coefficient from the vapor-gas mixture to the condensation surface is observed. The coefficient of heat transfer to the condensation surface depends on the concentration of non-condensable gases in the apparatus cavity. The results of the research indicate that it is possible to improve the heat exchangers with a jacket and allow an assessment of the heat input when removing the gas mixture from the jacket in the heating mode of the cookers at the design stage. Material research allows to develop automatiс systems and control parameters in the operation of apparatus with a jacket

Kalinina; E. N. Demina;The purification of industrial and surface wastewater from heavy metal ions (HMI) to requirements for the discharge of treated wastewater into natural waters is one of the most complicated environmental and technological problems. For the deep purification of waste water from the HMI, the use of cheap sorbents obtained from production waste is the most promising. One of the many-tonnage wastes of technology of inorganic substances is the sludge formed in the production of soda by the ammonia Solvay, s method. Currently, sludge is stored in sludge accumulators and is a long-term source of pollution of environmental objects. Scientific developments in the utilization of slimes with the production of building materials, etc., have not found wide practical use, which is due to the heterogeneity of the granulometric and chemical composition of the waste. Carried out X-ray phase analysis and studies of the physicochemical and chemical properties of waste samples showed that its main components are calcium carbonate (calcite) and calcium hydroxide (portlandite). It is known that the natural mineral limestone efficiently extracts HMI from aqueous solutions with the formation of less soluble basic salts, carbonates, and hydroxy carbonates of HM. It has been established that sludge samples have high sorption activity when copper(II) and zinc ions are extracted from low concentrated solutions (sorption capacity for copper ions is 35.0 mg/g, sorption capacity for zinc ions is 40 mg/g). To increase the operational properties, a method has been developed for the production of a modified granular sorbent based on the sludge of soda production, consisting in treating with sodium silicate. The effect of a dose of sodium silicate in the sorbent composition on the mechanical strength and sorption properties of the obtained samples was studied. It has been established that the introduction of 8,6% SiO2 into the sludge leads to an increase in the mechanical strength by 50–80%, and does not have a significant effect on the sorption activity of the material. The kinetic and sorption regularities of extraction of copper(II) ions and zinc on modified sorbents are revealed. Based on the analysis of the adsorption isotherms obtained, the adsorption equilibrium constants and maximum adsorption values (Amax (Cu2+) = 50.8 mg/g; Amax (Zn2+) = 97.1 mg/g) were determined. Obtained sorption materials can be recommended for wastewater treatment from HMI.
