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.

Исследование терминологии похоронно-поминальной обрядности считаем весьма актуальным по причине того, что в лингвокультурологическом аспекте терминология обряда мало изучена. Цель исследования заключается в систематизации терминов, относящихся к тематической группе «умереть» в содержании похоронно-поминального обряда в эвенской и якутской культурах. Метод. Обрядовые термины собраны методом сплошной выборки из словарей эвенского и якутского языков, материалов этнографических исследований. Результат. Тематическую группу номинаций с общей семантикой «умереть» можно разделить на следующие подгруппы: терминология, обозначающая «свою смерть», и терминология, связанная с убийством. Выводы. Тематическая группа номинаций с семантикой «умереть» демонстрирует общие закономерности образования слов. Каждый народ воспринимает окружающий его мир сквозь призму своих культурных обычаев, нравственных установок и принятых традиций.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2020Publisher:Tomsk Polytechnic University Authors: Vadim Z. Manusov; Boris Yu. 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.

Prospects of electro-technologies of the targeted energy delivery to single elements of food raw materials are substantiated. Hypotheses for the energy effective processes of dehydration, extraction and inactivation of microorganisms are formulated. On the base of the literature sources analyses and our study of the electromagnetic field interaction with food raw materials, the dimensionless complex – the number of energy action is offered. That number is used for the evaluation of mass-transfer processes energy and its kinetics. The modeling results of analytical and experimental processes for drying and pasteurization processes are represented. The steps of energy conversion in drying technologies are considered. Показано, что основные проблемы развития человечества (энергия, экология, пища) в первую очередь характерны для пищевых отраслей, а их решение связано с поиском принципиально новых подходов к термической обработке сырья. Обоснованы перспективы электротехнологий адресной доставки энергии к отдельным элементам пищевого сырья. Сформулированы гипотезы энергоэффективных процессов обезвоживания, экстрагирования и инактивации микроорганизмов. На основе критического анализа литературных источников и исследования механизмов взаимодействия электромагнитного поля с пищевым сырьем предложен безразмерный комплекс – число энергетического воздействия. Это число использовано для оценки энергетики процессов массопереноса и их кинетики. Представлены результаты аналитического и экспериментального моделирования процессов сушки и пастеризации. Рассмотрены этапы конверсии энергии в сушильных технологиях.

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.

Исследование терминологии похоронно-поминальной обрядности считаем весьма актуальным по причине того, что в лингвокультурологическом аспекте терминология обряда мало изучена. Цель исследования заключается в систематизации терминов, относящихся к тематической группе «умереть» в содержании похоронно-поминального обряда в эвенской и якутской культурах. Метод. Обрядовые термины собраны методом сплошной выборки из словарей эвенского и якутского языков, материалов этнографических исследований. Результат. Тематическую группу номинаций с общей семантикой «умереть» можно разделить на следующие подгруппы: терминология, обозначающая «свою смерть», и терминология, связанная с убийством. Выводы. Тематическая группа номинаций с семантикой «умереть» демонстрирует общие закономерности образования слов. Каждый народ воспринимает окружающий его мир сквозь призму своих культурных обычаев, нравственных установок и принятых традиций.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2020Publisher:Tomsk Polytechnic University Authors: Vadim Z. Manusov; Boris Yu. 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.

Prospects of electro-technologies of the targeted energy delivery to single elements of food raw materials are substantiated. Hypotheses for the energy effective processes of dehydration, extraction and inactivation of microorganisms are formulated. On the base of the literature sources analyses and our study of the electromagnetic field interaction with food raw materials, the dimensionless complex – the number of energy action is offered. That number is used for the evaluation of mass-transfer processes energy and its kinetics. The modeling results of analytical and experimental processes for drying and pasteurization processes are represented. The steps of energy conversion in drying technologies are considered. Показано, что основные проблемы развития человечества (энергия, экология, пища) в первую очередь характерны для пищевых отраслей, а их решение связано с поиском принципиально новых подходов к термической обработке сырья. Обоснованы перспективы электротехнологий адресной доставки энергии к отдельным элементам пищевого сырья. Сформулированы гипотезы энергоэффективных процессов обезвоживания, экстрагирования и инактивации микроорганизмов. На основе критического анализа литературных источников и исследования механизмов взаимодействия электромагнитного поля с пищевым сырьем предложен безразмерный комплекс – число энергетического воздействия. Это число использовано для оценки энергетики процессов массопереноса и их кинетики. Представлены результаты аналитического и экспериментального моделирования процессов сушки и пастеризации. Рассмотрены этапы конверсии энергии в сушильных технологиях.
