Abstract The development of agricultural technologies, the mechanization of the cultivation of ordinary crops for a long time has gone differently in different ways. The working bodies of agricultural machines process various materials, the number of which is increasing. In addition, the way the same material is processed often changes when trying to improve agricultural technologies. All this forces us to create new mechanisms of agriculture that were previously known. The use of replaceable gear bodies on flat cutting cultivators helps to reduce the energy intensity the process and improve the quality of non-falling soil. To protect against it, various agricultural techniques are recommended: plowing along the entire slope, deepening the arable layer, the formation of irregularities on the surface of arable land in the form of holes, intermittent furrows. The article describes the mechanized protection of the soil of the technological process and technical means for growing crops on erosive lands on the slope. Methodology for improving agricultural machinery for working on the slope of erosive dangerous lands. Ways to increase the stability of the movement of agricultural machines on slopes to improve the quality of technological operations are justified. The operating mode of the active disk needle is described.

The Impact

Качественный посев это не только равномерное распределением семян по длине рядка, но и их заделка на заданной глубине, позволяющая получить высококачественный урожай зерновых культур. Это достигается использованием рядового способа посева зерновых культур при помощи двухдисковых сошников, которые производят укладку посевного материала в борозду, что позволяет получить непосредственный контакт семян с почвой. Сеялки с такими рабочими органами используются как в традиционных, так и в минимальных технологиях возделывания зерновых культур. В статье представлены результаты теоретических исследований экспериментального сошника с направителем семян, рыхлителем почвы закрытого типа и бороздным прикатывающим катком с шиной из каучукового массива, определены зависимости для нахождения ударного коэффициента трения скольжения, а также зависимости скорости центра катка и семени после соударения. Статья посвящена улучшению качественных показателей посева семян зерновых культур сеялкой с экспериментальным сошником и содержит результаты теоретического исследования конструктивных и режимных параметров сошника с направителем семян, рыхлителем почвы закрытого типа и бороздным прикатывающим катком с шиной из каучукового массива. High-quality sowing is not only a uniform distribution of seeds along the length of the row, but also their seeding at a given depth, which allows getting a high-quality crop of grains. This is achieved by using an ordinary method of grain crops sowing using double-disc coulters, which place seeds in the furrow allowing direct contact of the seeds with the soil. Seeders with such working bodies are used in both traditional and minimal technologies for the cultivation of grain crops. The article presents the results of theoretical studies of an experimental coulter with a seed deflector, a closed-type soil cultivator and a furrow press wheel with a rubber mass tire. The dependences for finding the impact coefficient of sliding friction, as well as the dependence of the speed of the wheel center and seed after impact are determined. The article is devoted to the task of improving the quality indicators of sowing seeds of grain crops by a seeder with the experimental coulter and contains the results of a theoretical study of the design and operating parameters of the coulter with a seed deflector, a closed-type soil disrupturer and a furrow press wheel with a rubber mass tire.

The roller and sieve machines most commonly used in Russia for the post-harvest processing of root and tuber crops and onions have a number of disadvantages, the main one being a decrease in the quality of sorting due to the contamination of working bodies, which increases the quantity of losses during sorting and storage. To obtain high-quality competitive production, it is necessary to combine a number of technological operations during the sorting process, such as dividing the material into classes and fractions by quality and size, as well as identifying and removing damaged products. In order to improve the quality of sorting of root tubers and onions by size, it is necessary to ensure the development of an automatic control system for operating and technological parameters, the use of which will eliminate manual sorting on bulkhead tables in post-harvest processing. To fulfill these conditions, the developed automatic control system must have the ability to identify the material on the sorting surface, taking into account external damage and ensuring the automatic removal of impurities. In this study, the highest sorting accuracy of tubers (of more than 91%) was achieved with a forward speed of 1.2 m/s for the conveyor of the sorting table, with damage to 2.2% of the tubers, which meets the agrotechnical requirements for post-harvest processing. This feature distinguishes the developed device from similar ones.

Таким образом, возрастная динамика основных процессов запускает каскад реакций, проявляющихся в замыкании «патологических биохимических кругов», которые формируют предпосылки к развитию заболеваний и, с течением времени, клинические проявления. For the first time proteins are described, reliably increasing and decreasing in urine with age in the range of 20 to 60 years. The combinations of proteins associated with changes in immune processes, violation of blood reology, including the risk of coagulopathy, anticancer defense mechanisms, insulin signaling pathway, changes in cell characteristics are characterized division and quality of the newly formed fabric. Thus, the age dynamics of the main processes triggers a cascade of reactions manifested in the closure of «pathological biochemical circles» that form the prerequisites for the development of diseases and, over time, clinical manifestations.

Big Data, the Internet of Things, and robotic and augmented realities are just some of the technologies that belong to Industry 4.0. These technologies improve working conditions and increase productivity and the quality of industry production. However, they can also improve life and society as a whole. A new perspective is oriented towards social well-being and it is called Society 5.0. Industry 4.0 supports the transition to the new society, but other drivers are also needed. To guide the transition, it is necessary to identify the enabling factors that integrate Industry 4.0. A conceptual framework was developed in which these factors were identified through a literature review and the analytical hierarchy process (AHP) methodology. Furthermore, the way in which they relate was evaluated with the help of the interpretive structural modeling (ISM) methodology. The proposed framework fills a research gap, which has not yet consolidated a strategy that includes all aspects of Society 5.0. As a result, the main driver, in addition to technology, is international politics.

RESUMO: No momento de instabilidade econômica em que se encontra o país, ações que minimizem os gastos e que aumentem a produtividade na construção civil visando ao desenvolvimento sustentável dos meios de produção estão cada vez mais sendo solicitadas. Com o intuito de realizar um diagnóstico da disposição, organização e práticas nos canteiros de obra da região do Crajubar, foram estudadas dez construções em execução na região. A amostra selecionada contemplava edificações horizontais e verticais, com finalidade de uso comercial, residencial e mista. Os dados foram obtidos a partir do método de diagnóstico que consiste na aplicação de uma lista de verificação (check-list) padronizada, que contemplava três grupos a serem analisados: instalações provisórias, segurança na obra e movimentação e armazenagem de materiais. Para a visualização e identificação de falhas nos canteiros foi feito um registro fotográfico de itens pré-determinados. De posse das informações coletadas foram atribuídas notas para os grupos, calculada a nota global (que é a média aritmética das notas de grupo) e as obras foram distribuídas em quatro categorias: ótimas, boas, regulares e ruins. As obras horizontais obtiveram as piores notas, entre 4,01 e 6, enquanto as obras verticais que apresentavam políticas de gestão de qualidade se destacaram com as melhores notas, entre 8,01 e 10. O tipo de obra foi o fator que mais influenciou na qualidade dos canteiros de obras avaliados no Crajubar cearense.ABSTRACT: At a time of economic instability in the country, actions that minimize expenditures and increase productivity in civil construction aimed at the sustainable development of the means of production are increasingly being requested. In order to make a diagnosis of the layout, organization and practices in the construction sites of the Crajubar region, ten constructions were studied in the region. The sample selected included horizontal and vertical buildings, for commercial, residential and mixed use. The data were obtained from the diagnostic method, which consists of the application of a standardized checklist, which included three groups to be analyzed: temporary installations, handling and storage of materials. Along with this list, a photographic record of predetermined items was made for the visualization and identification of defects in the construction. From the information collected, the group notes and a global grade (the arithmetic mean of the group notes) were assigned and the works were distributed into four categories: great, good, regular and bad. The horizontal construction obtained the worse notes, between 4.01 and 6, while the vertical construction that presented policies of quality management stood out with the best notes, between 8,01 and 10. The type of construction was the factor that most influenced the quality of the construction sites evaluated in Crajubar cearense.
