This paper investigates the impact of tariff escalation on multinational suppliers relocating their production capacity to tariff-preferential regions with unreliable supply caused by low-production technology. We build a game theory model to analyze this issue based on three decisions for supplier-capacity relocation: no relocation, partial relocation, and full relocation. Our analysis finds that when tariffs are low or the production technology of the base in a preferential tariff region is not advanced, the supplier tends to adopt a partial-relocation strategy, but this strategy may be hindered by a manufacturer's order-allocation decision, leading to a no-relocation strategy as the supply chain's equilibrium. This may result in greater losses for the supplier. When tariffs are high or the production technology of the base in the preferential tariff region is advanced, the equilibrium strategy for the supply chain shifts to a full-relocation strategy. Interestingly, in the partial-relocation strategy, the higher production technology in the preferential tariff region negatively impacts the manufacturer's expected profits but benefits the supplier's expected profits due to the increased double marginalization. Finally, we find that the supplier can reduce the impact of tariffs by relocating their production capacity, especially with the partial-relocation strategy, as the supplier is always motivated to improve the production technology of the base in the preferential tariff region, with a potential purpose of transferring tariff costs to the manufacturer and consumers.

This work deals with the archaeometric investigation on 25 fragments of terra sigillata (red‐coated ceramic ware and moulds) found in the city of Arezzo, Tuscany (central Italy), and attributed to several important workshops from the first century BCE to the second century CE. Optical and spectroscopic techniques were used to analyse both the ceramic bodies and the red slips. All the potsherds showed a very fine‐grained ceramic body, sharing similar mineralogical compositions, mainly consisting in quartz, plagioclase, pyroxene, hematite, K‐feldspars, and illite/muscovite. The mineralogical data suggest that both the red‐coated wares and the moulds were produced using the same calcareous‐illitic clay and fired under oxidising conditions at temperatures between 850°C and 1000°C. A K‐rich illitic clay with a Fe content around 10–15% (in wt%) was used to elaborate the slips. Al‐substituted hematite was found in red slips by micro‐Raman spectroscopy. Comparison of the chemical data with terra sigillata from other important production areas in Italy and from other regions of the Meditteranean Sea, allowed to define that the studied samples, locally produced in Arezzo, differ systematically from all others, although they show similarities with nearby Pisan productions as well as those Puteolan.

The addition of rare earth metals to aluminum alloys can effectively improve their corrosion resistance and has been widely used in the aerospace and military industries. However, the current methods for the preparation of rare earth metals involve long processing steps, high energy consumption, and high carbon emissions, which severely constrains the development of aluminum alloys. Its output is further developed. To this end, this paper reviews mainstream rare earth production processes (precipitation methods, microemulsion methods, roasting-sulfuric acid leaching methods, electrochemical methods, solvent extraction methods, and ion exchange methods) to provide basic information for the green smelting of rare earth metals and help promote the development of green rare earth smelting. Based on the advantages and disadvantages of each process as well as recent research results, the optimal process parameters and production efficiency were summarized. Studies have concluded that the precipitation method is mostly used for the recovery of rare earth elements and related valuable metals from solid waste; the microemulsion method is mostly used for the preparation of nanosized rare earth alloys by doping; the roasting-sulfuric acid leaching method is mostly used for the treatment of raw rare earth ores; and the molten salt electrolysis method is a more specific method. This is a green and environmentally friendly production process. The results of this study can provide direction for the realization of green rare earth smelting and provide a reference for improving the existing rare earth smelting process.

In New Zealand, agriculture accounts for around 50% of total gross greenhouse gas emissions, energy production and use account for 40%. Given the limited possibility of reducing methane from the agricultural sector, we focus on the shape of, and factors influencing, the energy-related emissions profile. A single framework that combines environmental input–output analysis with structural decomposition analysis is established to systematically investigate driving forces shaping energy-related greenhouse gas emissions at national and sectoral levels. Results show that emission intensity, population, and consumption volume are dominant factors influencing shifting the energy-related emissions profile from 2007 to 2013. To achieve a net-zero-carbon economy, decarbonizing the transport sector is foremost and should be given priority. Policy directed at improving energy utilization in private consumption and exports, and the adoption and utilization of advanced technology in manufacturing, would contribute to achieving emissions reduction targets.

The paper presents the analysis of the weaponry items (108 arrowheads, 2 spearheads, and 2 glaive heads) recovered from the 17th–19th cc. burial ground of Kikki-Akki (Yamalo-Nenets Autonomous Okrug, Taz River) of the Upper Taz Selkups, aiming at the reconstruction of the technology of their production. With the aid of the methods of metallographic analysis, it has been established that the production of ferrous metal weapons was carried out by professional craftsmen. As raw materials, blacksmiths used malleable blooms, without special additional processing, consisting of unevenly carbonized steel and, less often, of iron or a mixture of both. Operations of smith forging of hot metal constituted the basis of the technology for the production of weapons. While doing so, the main attention was paid to finishing the external forms of the products, without using complex technological schemes. The production process, as a rule, was taking place at an optimal heating temperature. In general, weapons, although being not of a high quality, complied with technical specifications for their use.

Abstract While promoting manufacturing growth is imperative to boost economic growth, potential adverse consequences on natural resources and ecology have created sustainability-related concerns and challenges. In India, with the reform processes deepening further and the business environment becoming more market-oriented over the years, the adoption of appropriate measures for sustainable manufacturing growth under such conditions would require a deeper investigation of the underlying dynamics, particularly to address the impacts of external shocks. This is especially true when external shocks alter market dynamics and, hence, input is used significantly in the manufacturing sector. Given this backdrop, the present paper examines how the major external shocks to the Indian economy during in the post-reform era have altered the resource use patterns in selected manufacturing industries. The paper uses secondary data collected from the KLEMS database of the Reserve Bank of India for the period from 1980–81 to 2019–20 and applies descriptive statistics and econometric techniques to address the research objective. It is found that energy intensity, vertical integration, capital intensity, and rate of growth of total factor productivity decreased over the decades, whereas labour productivity experienced an increasing trend in most industries. However, the trends are mixed in the case of material intensity. Further, the regression results indicate significant effects of external shocks on resource use, factor productivity, and structural changes. There are also industry-specific differences in the nature and extent of such changes. Hence, a deeper investigation of the underlying factors and impacts at a disaggregate industry level is necessary to draw more robust insights.

Nowadays the organization of domestic serial production of high-tech products requires a lot of time. On the one hand, the reason is the restructuring of logistics chains with foreign suppliers, on the other hand, the building of cooperation in the country. For example, the duration of the implementation of promising production projects in the space industry is still years. Factories are changing approaches in the organization of work – one of the main ways to influence the duration of production is to reduce the time of their own production cycle. As a rule, the analysis of the organization of serial production begins with the final assembly, which determines the tact of work for all other sites that produce components. When evaluating the effectiveness of the organization of assembly production, criteria and factors are determined. The time of the product assembly cycle is taken as the efficiency criterion. It is necessary to determine the degree of significance for each factor and understand their mutual influence on each other. The purpose of the research is to develop a unified system of factors affecting the cycle, and a method based on this system for evaluating the effectiveness of the organization of assembly production. The article considers the technological process as a factor affecting the product assembly cycle.

Demand for hydrogen has grown and continues to rise as a versatile energy carrier. Hydrogen can be produced from renewable and non-renewable energy sources. A wide range of technologies to produce hydrogen in an environmentally friendly way have been developed. As the life cycle assessment (LCA) approach has become popular recently, including in the hydrogen energy system, this paper comprehensively reviews the LCA of hydrogen production technology. A subdivision based on the trends in the LCA studies, hydrogen production technology, goal and scope definition, system boundary, and environmental performance of hydrogen production is discussed in this review. Thermochemical hydrogen production is the most studied technology in LCA. However, utilizing natural resources, especially wind power, in the electrolysis process stands out as an environmentally preferable solution when compared to alternative production processes. It is crucial to rethink reactors and other production-related equipment to improve environmental performance and increase hydrogen production efficiency. Since most of the previous LCA studies were conducted in developed countries and only a few were from developing countries, a way forward for LCA application on hydrogen in developing countries was also highlighted and discussed. This review provides a comprehensive insight for further research on hydrogen production technology from an LCA perspective.

This study objects are juices from melon, watermelon, and pumpkin, as well as additives from apples, plums, pears, bell peppers, beets, carrots, aloe, melissa, and nettle. The problem addressed is minimizing melon crop losses. The research relevance stems from the need to reduce these losses. The development of multicomponent juices is aimed at the more efficient utilization of melon crops, contributing to the minimization of crop losses. Optimal component proportions were determined using sensory evaluation of organoleptic characteristics on a 5-point scale. The results showed that juice compositions with optimal component proportions have high organoleptic qualities and functional orientation. For melon juice, the optimal ratio was as follows: melon juice – 55 %, apple juice – 30 %, green bell pepper juice – 10 %, aloe juice – 5 %. For watermelon juice: watermelon juice – 65 %, plum juice – 25 %, beet juice – 5 %, melissa juice – 5 %. For pumpkin juice: pumpkin juice – 60 %, pear juice – 20 %, carrot juice – 15 %, nettle juice – 5 %. Critical control point (CCP) analysis was conducted at each production stage, from raw material acceptance to packaging and storage of the final product. This analysis identified potential risks and established control measures to minimize them. Developing multicomponent juices based on melon crops with plant based enriching additives allows the creation of products with high organoleptic qualities and functional orientation, contributing to efficient use of melon crops and reducing crop losses. Implementing the HACCP system at all production stages ensures product safety and high quality. This research offers a practical approach for the food industry to produce high-quality, functional beverages that maximize crop yields and ensure consumer safety. [ABSTRACT FROM AUTHOR]

Monographic processing of Avar Period (6–8th century) glass beads. Approx. 200 glass beads have been selected from 13 archaeological sites in current day Hungary as the representatives of typical Avar glass beads. The beads were analyzed with electron microprobe analyzer attached with wavelength dispersive X-ray spectrometer and/or energy dispersive X-ray spectrometer peripheries for 12–15 elements complemented with archaeological and color description. These beads provide insights primarily into the trade and interactions of the Avar population in the Carpathian Basin with other peoples. Through their analysis, we can learn about the economic systems associated with glass production and the connections between different regions. Furthermore, Avar Age glass beads offer valuable information about craftsmanship and artistic expression. Their diverse shapes, colors, and patterns showcase the skill and creativity of the artisans who made them, as well as hint at the production technology used. The purpose of data collection is to identify the raw materials and coloring agents used in bead production, detect potential chronological changes, internationally explore the identified production technology in terms of space and time, and outline the Avars' trade network, and provide reference for future research. This is the first ever published database of Avar Age glass beads.

Fragrant peanut oils (FPOs) are commonly defined as edible peanut oils having strong natural roasted peanut flavor without peculiar unpleasant odors and produced from peanut kernels through roasting/steaming and pressing operations, etc. The flavor of FPOs plays a crucial role in their acceptability and applications and their flavor profiles are an important factor in determining their overall quality. This paper presents a systematic literature review of recent advances and knowledge on FPOs, especially their flavors, in which it is focused on the evaluation of volatile compounds, the factors influencing the formation of flavor compounds, and formation mechanisms of those typical flavor compounds. More than 300 volatiles are found in FPOs, while some key aroma-active compounds and their potential formation pathways are examined. Factors that have big influences on flavor are discussed also, including the properties of raw materials, processing technologies, and storage conditions. Ultimately, the paper highlights the challenges facing, including the challenges in flavor analysis, the relationship between volatile compounds and sensory attributes, as well as the opening of the blackboxes of flavor formations during the processing steps, etc.

Applications of data envelopment analysis (DEA) often include inputs and outputs that are embedded in some other inputs or outputs. For example, in a school assessment, the sets of students achieving good academic results or students with special needs are subsets of the set of all students. In a hospital application, the set of specific or successful treatments is a subset of all treatments. Similarly, in many applications, labour costs are a part of overall costs. Conventional variable and constant returns-to-scale DEA models cannot incorporate such information. Using such standard DEA models may potentially lead to a situation in which, in the resulting projection of an inefficient decision making unit, the value of an input or output representing the whole set is less than the value of an input or output representing its subset, which is physically impossible. In this paper, we demonstrate how the information about embedded inputs and outputs can be incorporated in the DEA models. We further identify common scenarios in which such information is redundant and makes no difference to the efficiency assessment and scenarios in which such information needs to be incorporated in order to keep the efficient projections consistent with the identified embeddings.

The relevance of this study is the importance of investigating mathematical models and systems to optimize oil production in forecasting and regulating well stock in fuzzy environments. The purpose was to assess the practical application of Markov chain models and fuzzy set theory to optimize oil production. This study specifically analyzed operating and idle well stocks in Kazakhstan's Kenkiyak oil field using a Markov chain system of equations. Fuzzy set theory was then applied to model linguistic relationships between oil production parameters like depth and porosity. The Markov model successfully predicted linear asymptotes of well stock over time and assessed impacts of changing repair crew productivity. The fuzzy approach effectively modeled the dependence of production efficiency on depth and reservoir rock porosity. Results showed a 15% improvement in forecasting accuracy and a 10% increase in production efficiency. This demonstrates the value of mathematical models in optimizing real)world oil production processes and their ability to enhance management system performance. The models provide oil field designers with tools to better regulate well stock and staff operations. [ABSTRACT FROM AUTHOR]

The global demand for meat is projected to rise, necessitating a transformative shift in the meat industry towards sustainable and emission-neutral production models. For decades, price competition has driven intense rivalry among meat packers, with a focus on cost control and product differentiation. However, anticipated increases in input costs and challenges to meat supply present a unique opportunity for innovation. Meat production faces mounting pressures, particularly in Northern Europe, to transition from traditional industrialized systems to sustainable practices that address climate impacts. Despite substantial investments in alternative proteins, livestock remains an efficient converter of low-value inputs into high-value human nutrition. As meat becomes scarcer, its historical status as a luxury food is poised to resurface, offering a business opportunity for meat packers while prompting Western consumers to adopt more plant-rich diets. Technological advancements such as automation and AI have revolutionized meat production, enabling efficient processes, enhanced meat quality, and reduced environmental impacts. The future of meat production hinges on adopting circular and emission-neutral practices. The industry’s sustainability will depend on balancing efficiency with ecological harmony, transforming meat from a ubiquitous commodity to a luxury symbol of quality. Through technological innovation and a paradigm shift in production philosophy, the meat industry can meet the nutritional needs of a growing global population while adhering to stringent environmental standards.

Cell-based food, including cultured meat, introduces an innovative complement to our dietary options, introducing cellular agriculture and tissue engineering on the meat market together with traditional livestock farming. Originating from medical tissue cultivation techniques, this approach is now tailored for food production, prioritizing cost-effectiveness, palatability, and resource efficiency. As technology strives to efficiently upscale production, consumer acceptance stands as a key factor in adopting this new protein source. This review explores advances in cultivating muscle and fat tissues in vitro, emphasizing the importance of achieving muscle maturity, innovating scaffolds, and optimizing media composition to closely replicate the qualities of meat. It also addresses quality assessments of cultured meat based on its texture, nutritional content, and flavor. A concise examination of consumer perceptions reveals that acceptance is influenced by a blend of cultural, psychological, and social factors, balancing the positive potential outlook on cultured meat’s benefits for society, the environment, and animal welfare against concerns about its unnaturalness, uncertainty, and safety. Demographic trends suggest higher acceptance among younger, well-educated and urban individuals, contrasting with reservations from those more familiar with the traditional meat sector. Addressing these varied viewpoints is essential for a better understanding of public acceptance if cultured meat is effectively introduced into our future food systems. As media interest in this alternative is still high, aligning technological developments with consumer expectations is crucial for the potential market introduction of cultured meat.

The data of the metallographic study of sickles and knives (37 pcs) of the Petrovka Culture from the Southern Trans-Urals and the Middle Tobol River basin of the 19th–18th centuries BC are reported. The implements originate from settlements (Ustye 1, Kulevchi 3, Starokumlyak, Kamyshnoe 2, Ubagan 2, Nizhneingaly 3) and burial complexes (Ozernoe 1, Krivoye Ozero, Verkhnyaya Alabuga). The reconstruction of the manufacturing technology of the Petrovka Culture tools from the Southern Trans-Urals was carried out by both taking into account the results of the surface visual inspection, as well as by the data of the microstructural study of the metal. The metallographic analysis was conducted at the Tyumen Scientific Center of the Siberian Branch of the RAS (microscope Axio Observer D1m from Zeiss; microhardness tester PMT-3M from LOMO). A certain correlation was revealed between the functional purpose of the product, type of the raw material, and the tool manufacturing flowchart. The sickles and knives with handles are produced primarily from pure copper (including oxidised) both in the process of casting in mould with subsequent finishing, as well as in the result of the forming forging. The tools obtained in the casting process often had casting defects, accompanied by the phenomenon of shrinking warpage of the metal. The finishing of the copper tools was taking place in most cases either in the regime of incomplete hot forging at 300–500 C, or hot forging at 600–800 C and at near-melting temperatures of 900–1000 C. Most of the sickles in the forging process were purposefully hardened by forging on the cold metal. Unlike the sickles and knives with handles, shank knives are made mainly of low-alloyed tin bronze. Apparently, this category of tools was given a special ritual significance, especially considering the fact that about a third of the tools came from burial complexes with a specific selection of the related implements. The use of tin bronze in the production of knives significantly contributed to the fabrication of high-quality castings with the smooth surface without metal warping defects. The finishing of the knives after casting was carried out with heating up to 600–800 C or 900–1000 C (44 % of the tools) or in the regime of incomplete hot forging (25 %). The forging on the cold metal with annealing was rarely used. Thus, at the basis of the choice of the technological traditions of the metal production lies the availability of a certain raw material base, the type of the metal obtained from this ore, as well as the inheritance of the technologies from the preceding cultural communities. Technological innovations in the processing of non-ferrous metal, associated with the supply of Sn-bronzes in the form of ingots or finished products from Central Kazakhstan to the Southern Trans-Urals, led to the significant increase in the quality of the produce.

This paper investigates the impact of tariff escalation on multinational suppliers relocating their production capacity to tariff-preferential regions with unreliable supply caused by low-production technology. We build a game theory model to analyze this issue based on three decisions for supplier-capacity relocation: no relocation, partial relocation, and full relocation. Our analysis finds that when tariffs are low or the production technology of the base in a preferential tariff region is not advanced, the supplier tends to adopt a partial-relocation strategy, but this strategy may be hindered by a manufacturer’s order-allocation decision, leading to a no-relocation strategy as the supply chain’s equilibrium. This may result in greater losses for the supplier. When tariffs are high or the production technology of the base in the preferential tariff region is advanced, the equilibrium strategy for the supply chain shifts to a full-relocation strategy. Interestingly, in the partial-relocation strategy, the higher production technology in the preferential tariff region negatively impacts the manufacturer’s expected profits but benefits the supplier’s expected profits due to the increased double marginalization. Finally, we find that the supplier can reduce the impact of tariffs by relocating their production capacity, especially with the partial-relocation strategy, as the supplier is always motivated to improve the production technology of the base in the preferential tariff region, with a potential purpose of transferring tariff costs to the manufacturer and consumers.

Condition monitoring and predictive maintenance applications receive ongoing scientific attention in production technology. Larger companies, especially machine and component manufacturers, already offer related products. Small and medium-sized enterprises (SMEs) in particular show interest in developing and offering solutions in this market themselves to gain economic advantages, to improve resource utilization of their machines or to be able to offer these advantages to their own customers. In the development process, however, they often encounter problems already in the digitization of the machines. The first hurdle is to obtain an analysis-capable data set. This is due to the fact that common and established general data mining development process models, such as CRISP-DM, do not focus on production technology, causing difficulties for engineers during deployment. A problem with existing process models is the limited practicality in the engineering domain due to restricted adaptability. In a previous paper, a guideline for engineers for data mining suitable digitization of production machines was developed in order to solve these problems. The related results were provided in the context of a project for condition monitoring of mixing machines. In this paper, the proposed method is applied to components of a 5-axis CNC milling machine in three different monitoring use cases. A complete workflow is presented, including effect analysis, sensor selection, formulation of predictive scenarios, data preparation, training of machine learning algorithms and vizualization. Data and documentation are provided alongside this publication. [ABSTRACT FROM AUTHOR]

The Front Line demonstrations are designed carefully where provisions are made for speedy dissemination of high tech technologies among farming community through organization of other supportive extension activities, such as field days. Mungbean is the major kharif crop of Hanumangarh district contributing to farm income as well as maintaining the productivity of soils. However, the productivity of mungbean in the district is very low. The study was carried out by KVK, Sangaria (Rajasthan) on 325 Front Line Demonstrations of Mungbean organized during Kharif Seasons of the year 2017-18 to 2021 -22 at selected farmers fields. The package of improved technologies like line sowing, nutrient management, seed treatment and whole package were used in the demonstrations. The variety of mungbean MH 421 was included in demonstrations methods used for the present study with respect to FLDs and farmers' practices. The results found the maximum average yield of 952 kg/ha as compared to local farmer practice yield of 762 kg/ha being to 24.93% increased over check. The investigation reveals maximum average returns of Rs. 61880 per ha in compared to local farmer practices which gave average returns of Rs.49530 per ha. The average incremental B: C ratio was obtained 3.41 under improved technology. Favourable cost benefit ratio is self-explanatory of economic viability of the demonstrations and convinced the farmers for adoption of imparted interventions. The frontline demonstrations conducted on mungbean at the farmers' field revealed that the adoption of improved technologies significantly increased the yield as well as the net returns to the fanners. So, there is a need to disseminate the improved technologies among the farmers with effective extension methods like training and demonstrations. [ABSTRACT FROM AUTHOR]

Data on the volumes of imported and exported materials of the metallurgical industry in Russia are presented. The domestic industry, despite the rich mineral resource base, depends on imported supplies for a whole list of ore concentrates, oxides and other compounds, metals, and ferroalloys, as well as for certain grades of steel and metal products, which leads to high risks in the field of the country's security and sustainable development. The authors analyze the situation associated with the dependence on supplies of ore materials, metals, and alloys from abroad and give examples of promising technological options for the development of domestic production using Russia's own mineral resource base.

In this paper, we chose late war purple octagonal prismatic ware excavated at the Hejia Cemetery in Xianyang as the object of study, and carried out scientific analysis using ultra-deep field microscopy, scanning electron microscopy and energy spectrum analysis, X-ray diffraction, and microscopic Raman spectroscopy. First of all, the features of the formation and weathering process were determined, then the samples of unweathered areas obtained by the sectioning method were examined, and it was confirmed that all 12 samples are barium copper silicate with the main phases of Chinese violet (BaCuSi2O6) and Chinese dark blue (BaCu2Si2O7) colors. Based on compositional characteristics, etc. it was also found that this group of purple octagonal vessels embodies two different manufacturing processes and may represent an evolution of the process from lead-barium glass to cupro-barium silicate. On this basis, issues such as the population, distribution area and functional characteristics of this type of dish are discussed in order to obtain new ideas and evidence for relevant research.

The addition of rare earth metals to aluminum alloys can effectively improve their corrosion resistance and has been widely used in the aerospace and military industries. However, the current methods for the preparation of rare earth metals involve long processing steps, high energy consumption, and high carbon emissions, which severely constrains the development of aluminum alloys. Its output is further developed. To this end, this paper reviews mainstream rare earth production processes (precipitation methods, microemulsion methods, roasting-sulfuric acid leaching methods, electrochemical methods, solvent extraction methods, and ion exchange methods) to provide basic information for the green smelting of rare earth metals and help promote the development of green rare earth smelting. Based on the advantages and disadvantages of each process as well as recent research results, the optimal process parameters and production efficiency were summarized. Studies have concluded that the precipitation method is mostly used for the recovery of rare earth elements and related valuable metals from solid waste; the microemulsion method is mostly used for the preparation of nanosized rare earth alloys by doping; the roasting-sulfuric acid leaching method is mostly used for the treatment of raw rare earth ores; and the molten salt electrolysis method is a more specific method. This is a green and environmentally friendly production process. The results of this study can provide direction for the realization of green rare earth smelting and provide a reference for improving the existing rare earth smelting process.

AbstractAgricultural and food system transformation helps increase farm productivity and encourages farmers to participate in updated value chains, adopt newer technologies, thereby helping farmers transform their livelihoods in a sustainable manner. Relatedly, value chain innovations depend on multiple decisions farmers make at various stages of the value chain, adequate participation being a primary factor. In this paper, we integrate farmers’ adoption decision of a new variety of chilli crop (“Teja”) along with their electronic market participation decision and e-market participation intensity, based on data from the chilli farming sector in India, where agricultural markets have been modernized through digitization (Kalgudi e-Market). Thus, the employed Triple-Hurdle Model (THM) integrates adoption decision of “Teja” variety of chilli, e-Market Participation Decision and e-market participation intensity thereby, allowing us to make inferences relating to chilli farmers in Andhra Pradesh, India. Our results, showed that the drivers of “Teja” variety adoption, e-market participation, and e-participation intensity include education, reliable extension services, access to seeds of high yielding varieties, market information, and membership in farmer-producer organizations. Added to these, personnel training visits, prompt deliveries of inputs, and prompt payment of sales proceeds are also important in influencing participation and intensities. Results show that the three stochastic decisions of THM are strongly correlated implying that the adoption decision of “Teja” variety of chilli by the farmers influences the e-market participation decision and consequently, e-market participation intensity and these three decisions are sequential. On the contrary, the decisions viz., e-market participation decision and e-market participation intensity as input buyers and consequent adoption of “Teja” variety of chilli are simultaneous. So, the policy measures that promote production technology interventions (say, “Teja” variety of chilli) will definitely enhance better e-market access of chilli farmers. Accordingly, the breeding programs of the agricultural research stations should enhance the uptake of improved varieties in tune with modern marketing (e-market) technologies. Future farm policy and agricultural-research and innovations must recognize the potential that the digital marketing systems have to offer. Such considerations coupled with the provision of market infrastructure including assaying, grading, storage, and market information will promote digital transformation in agricultural value chains in developing countries like India.

In all-solid-state battery (ASSB) research, the importance of sulfide electrolytes is steadily increasing. However, several challenges arise concerning the future mass production of this class of electrolytes. Among others, the high reactivity with atmospheric moisture forming toxic and corrosive hydrogen sulfide (H2S) is a major issue. On a production scale, excessive exposure to H2S leads to serious damage of production workers' health, so additional occupational health and safety measures are required. This paper investigates the environmental conditions for the commercial fabrication of slurry-based sulfide solid electrolyte layers made of Li3PS4 (LPS) and Li10GeP2S12 (LGPS) for ASSBs. First, the identification of sequential production steps and processing stages in electrolyte layer production is carried out. An experimental setup is used to determine the H2S release of intermediates under different atmospheric conditions in the production chain, representative for the production steps. The H2S release rates obtained on a laboratory scale are then scaled up to mass production dimensions and compared to occupational health and safety limits for protection against H2S. It is shown that, under the assumptions made for the production of a slurry-based electrolyte layer with LPS or LGPS, a dry room with a dew point of τ = − 40   ∘ C and an air exchange rate of AER = 30   1 h is sufficient to protect production workers from health hazards caused by H2S. However, the synthesis of electrolytes requires an inert gas atmosphere, as the H2S release rates are much higher compared to layer production. [ABSTRACT FROM AUTHOR]

The dynamic die dry bending technology and its processing equipment were introduced. The technology could realize the softening, gluing, drying and non-destructive shaping of 360 ° arc bending of bamboo strips at one time, and realize the nin-free assembly of bamboo bending components, improving the automation and continuous level of bamboo bending products production. In addition, the method of segmental heating inside and outside at the same time makes the combined bamboo strips heated more evenly, and reduced the occurrence of cracks and glue opening. By adjusting the shape, size and curvature of the heating mold of the dynamic die dry bending equipment, the adhesive bending of multi-layer bamboo veneer was not only realized, the operating thickness of the bending part was increased, but also the bending and shaping of bamboo with various radians and shapes could be realized, and the operation was flexible. The related processing equipment included a dynamic die dry bending device and a hot press shaping device. The performance of bamboo bent products manufactured through the above equipment and methods could generally meet the relevant requirements of standards such as GB/T 3324-2017 General Technical Conditions for Wood Furniture, GB/T 35607-2017 Green Product Evaluation Furniture, and GB 18401-2020 National Basic Safety Technical Code for Textile Products.

Meat and meat products are among the main products of the human diet, which contain the essential nutrients, biological, macro and microelements that are important for the full functioning of the human body. Due to the significant environmental impact associated with industrial meat production, combined with the ever-growing world population, it is important to investigate the current state and production of the meat industry. The purpose of the study was to determine the volumes and possibilities of production of certain types of meat products in Ukraine, their market share, prospects for production in the future, and the ability to provide food industry enterprises with raw materials for the production of new food products. The work was carried out by analysing scientific, regulatory and technical literature, statistical evaluation of data, and comparing the results obtained with the findings of other scientists. The analysis of the industry indicates the decline of certain areas in animal husbandry, in particular, cattle breeding and the production of meat, meat products from beef and veal; a decrease in the number of farm animals, namely by 23% of bovine cattle, 6.9% of pigs, and 2.4% of poultry. During the analysed period, poultry meat production increased by 17%, while the number of business entities increased by 25 %. At the same time, beef and veal production decreased by 27.8%, while pork production increased by 33%. Based on the results obtained, it is possible to continuously provide processing enterprises with meat raw materials, namely, chicken meat for the production of meat products, and it is also relevant to introduce resource-saving technologies for obtaining a product with less weight loss and waste during processing. The study results can be used by enterprises when planning the release of products to the market, developing new recipes, improving existing production technologies, and understanding trends and volumes of meat and meat products on the Ukrainian market
