Published: April 2024

After a long way of development, leather production is considered as one of the leading industries in many countries of the world, using advanced achievements of science, technology and new technologies. Leather is considered a raw material after the use of animal products as meat products. However, many chemicals are additionally used to treat the skin. This creates a barrier to the environmental friendliness of the skin and the environment. But recently, due to environmental pollution, the question of replacing chemical production substances with natural substitutes has arisen. The purpose of the work is to replace chemical dyes with natural extracts in the leather industry in order to protect the environment, to determine the resistance of colored leather to water drops. This work was carried out in order to study the colour fastness of leather, what colored with natural extract. Colour fastness to water spotting was determined and analyzed. Walnut shells were used as extracts of natural dye. Three different samples were taken as control samples: a sample prepared using a standard chemical pigment, a sample prepared using water instead of a chemical pigment, and a leather sample that had not been finished. According to the results of the analysis, it was found that the leather dyed with natural extracts has a good coloring quality. Extract of walnut shell can be used as a dye instead of chemical pigments in the leather industry.

Authors: Zhamekova Zh. , Chomanov U.
Published: April 2024

In modern conditions scientifically proved requirements to quality of slaughter cattle and meat are defined by the standards considering conditions of manufacture of raw materials, its processing, requirements of the consumer. The standards formulate and regulate in detail the measures that control the quality of products. On the basis of standards are built procurement prices, premiums, discounts at all stages of production, circulation and consumption. Standards cannot remain unchanged for a long time, as the requirements for the quality of meat are constantly changing. This research work is aimed at developing a standard for cutting and deboning of cattle meat according to international requirements, which are exported to countries near and far abroad. This article presents the results of research related to international standards for cutting and deboning of veal carcasses. The fat content of young cattle meat has been estimated, as well as its classification by classes and additional classes and categories. Depending on age and breed, chemical and morphological compositions of meat of young cattle were studied. Qualitative indicators of post-slaughter meat of young cattle, the degree of maturity and meat spoilage were checked. The boundaries and cuts of their fore and hind quarters were also determined. As a result of the research, standard models of meat and fat coloration, marbling were studied and determined. The innovative technique of cutting and deboning of carcasses of cattle on the production sites of IE "Manashov A.A." and LLP "Meat Processing and Service" was introduced. The results of the analysis indicate the need to take into account these data in the development of technological scheme of cutting and deboning of veal carcasses, corresponding to international standards, and their subsequent implementation at meat processing enterprises of the Republic of Kazakhstan.

Published: April 2024

Currently, the meat industry has accumulated considerable experience in the efficient processing of cattle byproducts. But the share of their use for food purposes remains low. This concerns, first of all, the treatment of the multicameral stomach of cattle. The future direction of scientific research is the use of these by-products in full. This article discusses the technological processes of processing by-products of cattle (tripe and reticulated tripe) using waste from the dairy industry. One of the concrete and effective ways to solve the problem is to carry out the processes of biotechnological processing of cattle. To reduce the time of heat treatment and eliminate the specific odor characteristic of the scar, and to reduce the mechanical strength, a technology for processing cattle rumen with whey is proposed. The nutritional value and consumer properties of cattle by-products (rumen, reticulated rumen) have been investigated as a source of food raw materials, the prospects of use are assessed. In this work, the possibility of treating the scar of cattle with serum was investigated. Studies of the physico-chemical composition and biological value of by-products have shown a high content of proteins and minerals, amino acids in the abdominal and retina. A solution of whey is recommended for softening and cleansing the rumen of cattle and reticulated cattle. Processing of collagen-containing raw materials with biologically active substances using whey microorganisms should be recognized as one of the promising areas.

На примере Вологодской области проанализирована динамика земель лесного фонда за период с 2008 по 2021 гг. В основу положены материалы учета лесного фонда и натурных исследований авторов. Установлено, что за анализируемый период лесистость Вологодской области снизилась с 69,9 до 68,3 %. При этом площадь хвойных насаждений сократилась с 5009,9 до 4985,1 тыс. га, а площадь мягколиственных – с 4924,6 до 4744,9 тыс. га. Другими словами, площадь покрытых лесной растительностью земель сократилась на 204,5 тыс. га. Основные изменения площади земель, покрытых лесной растительностью, объясняются доминированием сплошнолесосечных рубок в практике лесопользования и медленным последующим лесовосстановлением вырубок. Так, за анализируемый период площадь гарей сократилась с 7,2 до 1,16 тыс. га, погибших насаждений – с 1,1 до 0,79 тыс. га, прогалин и пустырей – с 1,9 до 1,08 тыс. га. При этом площадь вырубок увеличилась с 170,9 до 353,76 тыс. га. Последнее объясняется несоответствием распределения объемов работ по способам лесовосстановления. Так, на долю искусственного лесовосстановления приходится 10, комбинированного – 4 и естественного – 86 %. В целях ускорения перевода вырубок в покрытые лесной растительностью земли целесообразно увеличить долю комбинированного лесовосстановления и минерализации почвы как меры содействия предварительному и последующему лесовосстановлению.

Jn the example of the Vologda Region the dynamics of the forest fund lands for the period from 2008 to 2021 is analyzed. The research is based on the materials of the forest fund accounting and field studies of the author. It was established that during the analyzed period, the forest cover of the Vologda region decreased from 69.9 to 68.3 % at the same time the area of coniferous plantations decreased from 5009.9 to 4985.1 thousand ha and the area of softwood from 4924.6 to 4744.9000 ha. In other words, the area covered with forest vegetation decreased by 204.5 thousand ha. The main changes in the area of land covered with forests are explained by the dominance of clear cutting in the practice of forest management and the slow subsequent reforestation of cut down lands. Thus, during the analyzed period, the area of burnt out area decreased from 7.2 to 1.16 th. ha, dead plants from 1.1 to 0.79 th. ha, bare places and wastelands from 1.9 to 1.08 th. ha. At the same time the cleared area increased from 170.9 to 353.76 th. ha. The latter is explained by the inconsisteney in the distribution of the scope of work according to the methods of reforestation. So, the share of artificial restoration accounts for 10, combined 4 and natural 86 %. In order to accelerate the transfer of cuttings in forested lands it is advisable to increase the proportion of combined reforestation and soil mineralization as a measure to promote pre and post reforestation.

Authors: Nurjanah Listia , Limanda Kelfi Yanti
Published: April 2024

Rapid developments in the skincare industry have created increasingly fierce competition and require the development of effective marketing strategies. In this context, influencers are one of the strategies adopted to support marketing efforts in the industry. Therefore, this research aims to evaluate the main factors influencing Generation Z's buying interest in skincare products in Batam City. Data was collected through a questionnaire distributed to Generation Z, which is interested in skincare products as research objects and has 321 respondents. The data analysis method used is SmartPLS 3.0, with a quantitative analysis approach. The research results show that influencers who meet the criteria of attractiveness, expertise, social media influence, and EWOM influence the image of skincare brands. The image of the skincare brand also significantly influences Generation Z's buying interest in Batam City. The mediating role of brand image influences attractiveness, expertise, social media influence, and EWOM on purchase intention. However, there is a criterion for influencers, namely trustworthiness, which does not significantly influence the skincare brand's image. Apart from that, the role of skincare brand image does not influence trustworthiness on purchase intention.
Social Life Cycle Assessment of Solar Dryer House for Postharvest Loss Management Technology in Tanzania
Authors: Mwaijande Francis
Published: April 2024

Agricultural products are dried to improve their life-span, enable storage stability, and reduce postharvest losses. Open-sun crop drying is the most popular method in Sub-Saharan Africa because it has a lower energy cost. However, this method is more often unsuitable due to climatic conditions in some areas, resulting in poor-quality drying and spoiled food products. Solar dryer house technology is designed to address challenges related to cleaner energy costs for efficient post-harvest loss management. Life Cycle Sustainability Assessment (LCSA) is a methodology used to integrate a compatible analysis of three pillars of sustainability: economy, environment, and society. Social Life Cycle Assessment (S-LCA), on the other hand, is a methodology used to cover the social aspects of sustainability. This article examines the S-LCA of solar dryer house technology for post-harvest loss management. It found that S-LCA is a useful framework for sustainability assessment and social impact estimation for analyzing the effects of products or services on stakeholders at local, national, and global levels beyond environmental and economic impact. The article contributes to knowledge and understanding of UNEP and SETAC guidelines in Africa.
Technical Note: A simple feedforward artificial neural network for high temporal resolution classification of wet and dry periods using signal attenuation from commercial microwave links
Authors: Øydvin Erlend , Graf Maximilian , Chwala Christian , Wolff Mareile Astrid , Kitterød Nils-Otto , Nilsen Vegard
Published: April 2024

Abstract. Two simple feedforward neural networks (MLPs) are trained to classify wet and dry periods using signal attenuation from commercial microwave links (CMLs) as predictors and high temporal resolution reference data as target. MLPGA is trained against nearby rain gauges and MLPRA is trained against gauge-adjusted weather radar. Both MLPs perform better than existing methods, showcasing their effectiveness in capturing the intermittent behaviour of rainfall. This study is the first using both radar and rain gauges for training and testing for CML wet-dry classification. Where previous studies has mainly focused on hourly reference data, our findings show that it is possible to predict wet and dry periods with a higher temporal precision.
Examination of Analytical Shear Stress Predictions for Coastal Dune Evolution
Authors: Cecil Orie , Cohn Nicholas , Farthing Matthew , Dutta Sourav , Trautz Andrew
Published: April 2024

Abstract. Existing process-based models for simulating coastal foredune evolution largely use the same analytical approach for estimating wind induced surface shear stress distributions over spatially variable topography. Originally developed for smooth, low-sloping hills, these analytical models face significant limitations when the topography of interest exhibits large height-to-length ratios and/or steep, localized features. In this work, we utilize computational fluid dynamics (CFD) to examine the error trends of a commonly used analytical shear stress model for a series of idealized two-dimensional dune profiles. It is observed that the prediction error of the analytical model increases as compared to the CFD simulations for increasing height-to-length ratio and localized slope values. Furthermore, we explore two data-driven methodologies for generating alternative shear stress prediction models, namely, symbolic regression and linear, projection-based, non-intrusive reduced order modeling. These alternative modeling strategies demonstrate reduced overall error, but still suffer in their generalizability to broader sets of dune profiles outside of the training data. Finally, the impact of these improvements to aeolian sediment transport fluxes is examined to demonstrate that even modest improvements to the shear stress prediction can have significant impacts to dune evolution simulations over engineering-relevant timescales.
Characteristics and dynamics of extreme winters in the Barents Sea in a changing climate
Authors: Hartmuth Katharina , Wernli Heini , Papritz Lukas
Published: April 2024

Abstract. The Barents Sea is experiencing large trends in sea ice decline and increasing surface temperatures while at the same time, it is a key region of weather variability in the Arctic and therefore predestined for the occurrence of surface weather extremes. In this study, we identify extreme winter seasons in the Barents Sea, based on a multivariate method, as winters with large seasonal-mean anomalies in one or several surface parameters encompassing surface temperature, precipitation, surface heat fluxes and surface net radiation. Using large-ensemble climate model data for historical (S2000) and end-of-century (S2100) projections following a RCP8.5 emission scenario, we find distinct clusters of extreme winters that are characterized by similar combinations of anomalies in these key surface weather parameters. In particular, we find that, during extreme winters, seasonal-mean anomalies in surface temperature are usually spatially extended with a maximum over sea ice in S2000 simulations, which shifts towards the continental land masses in a warmer climate, as the formation of a warm or cold air reservoir is being hampered by the increasing area of open ocean. Several extreme winters are selected for a detailed investigation of their substructure focusing on the relative importance of anomalies in the occurrence of synoptic-scale weather systems and anomalous surface boundary conditions for the formation of such seasons. Large combined anomalies in the key surface parameters result mainly from the accumulation of recurrent short-term events that are linked to distinct patterns of anomalous frequencies in cyclones, anticyclones and cold air outbreaks. While large seasonal-mean anomalies in surface air temperature can be linked to large-scale patterns facilitating the horizontal advection of relatively warmer (colder) air, which coincides with a lack (surplus) of cold air outbreaks, precipitation anomalies are characterized by local anomalies in cyclone and anticyclone frequency. Additionally, anomalous surface boundary conditions – that is sea ice concentration and sea surface temperatures – facilitate the formation of persistent anomalous surface conditions or further enhance atmospherically driven anomalies due to anomalous surface heat fluxes. In a warmer climate, we find extreme winters with similar substructures as in S2000. However, the increasing distance of the Barents Sea to the sea ice edge causes a decreasing magnitude in seasonal-mean anomalies of surface air temperatures and the atmospheric components of the surface energy balance. A decrease in the variability of both sea ice and sea surface temperatures indicates a decreasing importance in anomalous surface boundary conditions for the formation of future extreme winters in the Barents Sea, while the robust link shown for surface weather systems persists in a warmer climate.
HyDesign: a tool for sizing optimization of grid-connected hybrid power plants including wind, solar photovoltaic, and lithium-ion batteries

Published: April 2024

Abstract. Hybrid renewable power plants consisting of collocated wind, solar photovoltaic (PV), and lithium-ion battery storage connected behind a single grid connection can provide additional value to the owners and society in comparison to individual technology plants, such as those that are only wind or only PV. The hybrid power plants considered in this article are connected to the grid and share electrical infrastructure costs across different generation and storing technologies. In this article, we propose a methodology for sizing hybrid power plants as a nested-optimization problem: with an outer sizing optimization and an internal operation optimization. The outer sizing optimization maximizes the net present values over capital expenditures and compares it with standard designs that minimize the levelized cost of energy. The sizing problem formulation includes turbine selection (in terms of rated power, specific power, and hub height), a wind plant wake loss surrogate, simplified wind and PV degradation models, battery degradation, and operation optimization of an internal energy management system. The problem of outer sizing optimization is solved using a new parallel “efficient global optimization” algorithm. This new algorithm is a surrogate-based optimization method that ensures a minimal number of model evaluations but ensures a global scope in the optimization. The methodology presented in this article is available in an open-source tool called HyDesign. The hybrid sizing algorithm is applied for a peak power plant use case at different locations in India where renewable energy auctions impose a monetary penalty when energy is not supplied at peak hours. We compare the hybrid power plant sizing results when using two different objective functions: the levelized cost of energy (LCoE) or the relative net present value with respect to the total capital expenditure costs (NPV/CH). Battery storage is installed only on NPV/CH-based designs, while the hybrid design, including wind, solar, and battery, only occurs on the site with good wind resources. Wind turbine selection on this site prioritizes cheaper turbines with a lower hub height and lower rated power. The number of batteries replaced changes at the different sites, ranging between two or three units over the lifetime. A significant oversizing of the generation in comparison to the grid connection occurs on all NPV/CH-based designs. As expected LCoE-based designs are a single technology with no batteries.

Published: April 2024

The article aims to consider the phonetic features of island Russian-German dialects of the Krasnoyarsk region. The research material was the author's corpus of oral texts of culinary recipes recorded by digital audio recording during dialectological expeditions to the former German villages of the Krasnoyarsk region. General phonetic features of the studied High German dialects of the Germans of the Krasnoyarsk region (settlers from the Volga region and their descendants), reflected in the dialect texts of culinary recipes, transmit the features characteristic of the West Middle German dialect area with a Rhenish-Frankish basis. Consonantal changes illustrate the nature of the second (High German) movement of Germanic consonants of the specified dialect area. The phonetic features of the German dialects of the Krasnoyarsk region, described in the article on the material of the culinary recipe texts, clarify the existing views about the current state of the island dialect language system, the description of which is important for further study of German dialectology and the theory of languages interaction.

The paper provides an overview of the components of the pilot model used to design the flight control system which focuses on the physiological aspects and aspects of manual control. The structure of a multi-element system is used which allows the authors to reveal the totality of interaction between the pilot and the aircraft during the implementation of manual control. Manual control is the most difficult process when performing an aircraft flight and requires a lot of experience and high pilot skills. The sensory and intersensory models of the pilot–aircraft system are considered. The application of these models requires knowledge of the mechanisms and processes that are directly involved in the development of the pilot's spatial orientation when controlling the aircraft manually. The development of a method and a mathematical model for the formation of spatial orientation skills is an urgent task of scientific research.
A Study on the Policy Agenda Setting and Policy Decision-Making Process of the ‘Double Reduction’ Policy in China using Kingdon’s Multiple Streams Model
Authors:   Korea Society Of The Politics Of Education, Kim SangCheol , Wei Wei , Joo YoungHyeo
Published: April 2024

This study aimed to analyze the policy formation process of the ‘Double Reduction’ Policy (DRP) based on Kingdon’s multiple streams model. As a result of the study, the problems stream refers to the problem of inequity in education, heavy homework burden and overheated extracurricular education destroying the educational order, leading to social problems and becoming a national issue. In order to solve these problems, the government and educational experts discussed, revised, and reunited countermeasures and previous policies and created policy alternatives. The politics stream is the core variable, which solves the academic burden problem in the education reform process through factors such as national emotions and changes in national educational development concepts. The educational development concept of “strengthening moral education and cultivating people” and maintaining educational equity have strongly impacted on the derivation, development, and transformation of policies to reduce student burden. A significant opportunity to create a “policy window” by combining the above three streams was realized through the combination of national ‘Two Sessions’ in 2021 and the opening of the 19th meeting of the comprehensively deepening reform Committee on May 21, 2021. The policy intention to reform school education and regulating off after-school educational training was raised as a policy agenda, and the DRP was eventually formed.

The events in Ukraine in 2022 had a devastating effect on its population.  The authors of this paper considered whether it would be possible to strengthen both Ukrainian and other young people’s cognitive resilience in the face of different forms of conflict if they were put into contact with students in other countries. One potential means for building this resilience that could be explored in a classroom setting was the provision of a platform through which to compare perspectives with fellow students of other nationalities while gaining exposure to and practical experience with a set of cognitive tools for understanding and addressing challenging situations.  The Digital Bridge Project (DPB) was designed to improve these students’ English and critical analysis skills through direct exchange with their counterparts in other parts of the world via five online interviews in which they explored decision-making tools proposed by a variety of authors. The following case study describes how the Project was conducted. Three Ukrainian universities and the University of Europe for Applied Sciences in Iserlohn, Germany participated in this study. The results of the Project indicate that it is a model that can be applied effectively in a variety of subject areas. The authors recommend that schools and universities wishing to emulate the model discussed here should adapt the format to their specific needs. The results of the student surveys from both countries involved indicate that the method can empower students to address a wide range of disruptive forces in business and society with tools that are part of a 21st century skill set for both enhancing managerial decision-making and encouraging participatory democracy.

Associations between precarious employment trajectories and mental health among older workers in Germany: Vertical and horizontal inequalities
Authors: Rohrbacher Max , Hasselhorn Hans Martin , Matilla-Santander Nuria
Published: April 2024

OBJECTIVE: The aim of the study was to investigate the longitudinal association between multi-dimensionally measured precarious employment (PE) trajectories and mental health among older employees in Germany.

METHODS: Current data from the German lidA study was used, including panel cases, who participated in all four survey waves (2011, 2014, 2018, 2022). The study comprised 1636 subjects, aged 46 and 52 years at baseline. Group-based trajectory modelling was used to model PE trajectories based on a score combining multiple items from the dimensions employment insecurity and income inadequacy. The association between PE trajectories (2011–2022) and mental health (2022) was tested using weighted logistic regression.

RESULTS: We identified a PE trajectory with upward movement that best described 13.6% of the study sample. Representation in this group was socially unequally distributed with noticeably larger shares of female, lower-educated and lower-skilled workers in PE. Women following this trajectory had increased odds [odds ratio (OR) 1.68–1.82] of reporting poor mental health in 2022 compared to their counterparts in constant non-PE. This was not the case for men (OR 0.37–0.51).

CONCLUSIONS: Our findings highlight horizontal and vertical inequalities with respect to exposure to and consequences of PE. Future labor market reforms should improve protection of women, who will likely be disadvantaged by accumulating employment-related mental health risks over the course of their lives.
