Research of physical and mechanical properties of knitted fabrics of plush interlooping with reduced material consumption

The article discusses methods for manufacturing lined weave plush knitwear and ways to reduce the material intensity of knitted fabrics. The purpose of the study is to reduce the material consumption of products while maintaining operational, hygienic and aesthetic properties in the production of knitted fabrics. As a result of experimental work, the technological capabilities of the KН-323D flat knitting machine were studied and new types of lined weave plush knitwear were developed. Comparing the bulk density of plush knitwear with elongated lining broaches with the main base weave, it is clear that the presence of elongated lining broaches in the knitwear structure increases the thickness of the knitwear and reduces the bulk density. The breathability of a lined weave plush jersey is significantly less than that of a basic weave. It has been established that air permeability coefficients can be reduced to 33.1% (46.3-66.9 cm3/cm2∙sec) by adjusting the length of the threads of the lining broaches of plush knitted fabric of lined weave. Regression equations are derived to determine the dependence of bulk density, breaking load (along the length and width) and the air permeability index of knitted fabric on technological factors. Mathematical models were built in Excel using regression equations. The research results make it possible to improve the quality and consumer properties of knitted products, and to select advanced production technologies for their production.

Regional differences and improvement potential of carbon emission efficiency in China’s power industry: insights from meta-frontier DEA model considering integer constraints

Previous studies on the carbon emission efficiency (CEE) in the power industry have neglected concerns related to regional heterogeneity and the integer character of certain indicators. In response to these issues, this study proposes a meta-frontier DEA model that integrates integer constraints for evaluating the CEE of China’s provincial power industry from 2011 to 2021. This study also proposes to apply the Theil, technology gap ratio, and inefficiency decomposition indexes to analyze regional disparities, technological gaps, and strategies for enhancing CEE within China’s provincial power industry. The research findings highlight several key points. First, China’s power industry exhibits inefficiencies in CEE. The central region mainly contributes to the overall CEE decline, and approximately 70% of provinces demonstrate an average CEE below 0.70. Second, the technological level of the western region is leading, while that of the central region is the worst. Specifically, Ningxia, Hainan, and Jiangsu have the most advanced production technology levels. Third, substantial disparities in CEE within China’s power industry primarily stem from regional imbalances in development. Fourth, technical inefficiency contributed 68.24% of the CEE in the central region, and management inefficiency contributed 96.91% and 65.42% in the western and eastern regions, respectively. Overall, China’s power industry still has 37% potential for improvement.

As an alternative energy carrier, it can be produced using various conventional and advanced technologies, aiming for a decarbonized energy future. Currently, H2 production heavily depends on fossil fuels, which results in carbon emissions and makes the process energy-intensive, posing a significant risk.This review article discusses the commonly employed hydrogen production approaches, their current opportunities, and their strategic design towards a global hydrogen economy. Various reforming methods are also explored, along with the specific raw ingredients used in the generation process. Additionally, the production of bio-hydrogen is addressed, with a special focus on fermentation (dark and photo-fermentation), direct bio-photolysis, and indirect bio-photolysis. Bio-hydrogen is gaining popularity due to its environmentally friendly nature and the wide range of feed materials available for its production.The review provides comprehensive information on the biological conversion processes for H2 production. While numerous researches have been reported, there is still room for improving the efficiency of large-scale H2 production to meet the growing demand.

Functionalized palm biomass-derived activated carbon for the removal of Pt(IV) from a simulated leachate

Over the years, demand for Platinum Group Metals (PGMs) has grown steadily due to increased production of various advanced technologies, such as automotive and electronic products. PGMs are predominantly used in automotive catalysts in the automotive industry. Along with the increase in automotive production, deactivated automotive catalysts pose environmental and health hazards. These wastes are excellent alternative sources of PGMs, which can be exploited to bridge the gap between the demand and supply of PGMs. Adsorption is one of the most popular metal removal/recovery methods due to its various advantages, such as ease of use and cost-effectiveness. In consideration of this method, developing an inexpensive and efficient adsorbent is a crucial point. Thus, activated carbon (AC), derived from a palm kernel shell that is abundantly available in Indonesia, was functionalized using ionic liquid (ACIL) and used for Pt(IV) removal from a simulated automotive catalyst waste leachate. The functionalized AC showed a high adsorption capacity (178.6 mg g−1), in which the adsorption of Pt(IV) followed a chemisorption route, fitting with the monolayer model. The functionalized adsorbent also showed excellent performance during continuous Pt(IV) adsorption from simulated leachate. Recovery of precious metals, such as Pt(IV) and Pd(II), from the simulated leachate containing other metals was possible by maintaining the high hydrochloric acid concentration. Furthermore, targeted separation of Pt(IV) was achieved through sequential desorption using NaClO4. In addition, ACIL showed remarkable reusability after being used for three cycles without showing a noticeable decrease in performance. Thus, this study highlights the capability of a functionalized adsorbent from palm oil industry biomass to recover precious metals from simulated leachate of automotive waste.

Forestry Resource Efficiency, Total Factor Productivity Change, and Regional Technological Heterogeneity in China

The efficient and sustainable management of forestry resources is crucial in ensuring economic and societal sustainability. The Chinese government has invested significantly in regulations, afforestation, and technology to enhance the forest resource efficiency, reduce technological disparities, and boost productivity growth. However, the success level of this undertaking is unclear and worth exploring. To this end, this study applied DEA-SBM, meta-frontier analysis, and the Malmquist productivity index to gauge the forest resource efficiency (FRE), regional technology heterogeneity (TGR), and total factor productivity growth (MI) in 31 Chinese provinces for a study period of 2001–2020. Results revealed that the average FRE was 0.5430, with potential growth of 45.70%, to enhance the efficiency level in forestry resource utilization. Anhui, Tibet, Fujian, Shanghai, and Hainan were found to be the top performers in forestry utilization during the study period. The southern forest region was ranked highest, with the highest TGR of 0.915, indicating advanced production technologies. The average MI score was 0.9644, signifying a 3.56% decline in forestry resource productivity. This deterioration is primarily attributed to technological change (TC), which decreased by 5.2%, while efficiency change (EC) witnessed 1.74% growth over the study period. The Southern Chinese forest region, indicating an average 3.06% increase in total factor productivity, ranked highest in all four regions. Guangxi, Tianjin, Shandong, Chongqing, and Jiangxi were the top performers, with prominent growth in MI. Finally, the Kruskal–Wallis test found a significant statistical difference among all four regions for FRE and TGR.

Carbon footprints of solar panels in China provinces based on different production and waste treatment scenarios

The ambitious goal of reaching net-zero worldwide has promoted the development of renewable energy, but the seemingly green energy also requires massive resource and energy consumption during its lifecycle. Especially for China, the top solar panel manufacturer and user, the environmental impacts of solar systems should be concerned in the long-term, particularly in the field of retired photovoltaic (PV) recycling. However, provincial carbon footprints of solar panels based on different production and waste treatment techniques have not been estimated before, including the accumulated and potentially reduced amount of carbon footprints (compared with designed optimal scenarios) in China. This research aims to calculate the total and reduced carbon footprints of solar panels by using the provincial electricity generation data of PVs in China. Results show that the national accumulated carbon emissions of installed panels from 2011 to 2035 would exceed 5 Gt CO2eq by 2060. With advanced production technology and efficient waste treatment, the emissions could be significantly reduced by 50% for the whole lifecycle and 36% for recycling. Although large emission variations existed among provinces, the dominant emission sources shifted from the northwest to eastern regions of China in recent years. Our study provides fundamental guidance to the governmental regulations of waste PVs as well as technological development of recycling treatment scenarios.

Scenario forecasting of the dynamics of Russian production technologies using spatial SAR models

Relevance. The development and implementation of advanced production technologies are the most important factors of economic growth and competitiveness in the modern economy. Predicting their dynamics, taking into account the spatial features of localization, is a difficult and time-consuming task. The spatial effects resulting from the impact of the surrounding territories play a significant role in the dynamics of advanced production technologies in the regions of Russia. Accounting for these effects is necessary when constructing scenario models in conditions of strong spatial heterogeneity of the studied processes. Traditional forecasting methods do not take into account spatial interdependencies and are not able to reflect the influence of surrounding regions on the development of technologies. Research objective. Assessment and scenario forecasting of the dynamics of advanced production technologies being developed in the regions of Russia using SAR models that allow taking into account spatial effects between regions. Data and methods. For scenario forecasting of the dynamics of advanced production technologies being developed in the Russian regions, taking into account spatial effects, a methodological approach was developed based on the modeling of the spatial log (SAR) of the processes of their development, autoregressive (ARMA) modeling and forecasting of the key factors of their dynamics. Taking into account spatial effects and heterogeneity, the proposed approach to modeling makes it possible to more accurately predict the dynamics of advanced production technologies in the Russian regions. Results. The developed methodological approach was tested to form predictive scenarios for the dynamics of advanced production technologies being developed in the regions of Russia. In particular, an inertial forecast scenario was developed, assuming the preservation of current trends in the dynamics of the technologies being developed, as well as two extreme possible scenarios – optimistic and pessimistic. With the help of the spatial SAR model, a significant influence of the number of research organizations on the volume of advanced production technologies generated was confirmed, and in the second group of regions, the influence of the number of technicians who conduct research and development was confirmed. The novelty of the study is to take into account the spatial features of the localization of the advanced production technologies being developed, as well as the spatial effects resulting from the impact of the surrounding regions on the creation of new technologies. This approach makes it possible to significantly reduce errors in the formation of forecast scenarios in conditions of significant spatial heterogeneity of the initial data. Conclusions. To intensify the generation of new technologies in the regions of the second group, it is necessary to attract personnel with technical specialties. The dynamics of the technologies being developed in the first group of regions with a powerful research potential are also influenced by the number of research personnel and the amount of attracted financial resources for fundamental and applied research. To increase the activity of these regions in the development of advanced technologies, it is necessary to form and develop relationships with the surrounding regions.

Оценка ресурсной обеспеченности: от ЕАЭС к Большому евразийскому пространству

Considering the transformation of global economic relations, Russia strives to strengthen cooperation within the Greater Eurasian space (GES) on the basis of the Eurasian Economic Union (EAEU). The study aims to develop an approach to assessing the resource provision of the GES development. The Balassa method and the analysis of documents were used to distinguish five institutional levels (beyond the EAEU) of the GES development: I — countries that have a free trade zone agreement with the EAEU; II — countries that have other agreements; III — cooperation is elaborated; IV — negotiations were conducted; V — countries interested in cooperation. According to 4 traditional production factors, 8 types of resource provision were revealed: raw, agroclimatic and food, labour, intellectual, production capacity, transport infrastructure, innovation, financial. For their assessment, the following statistical and authors’ indicators can be used: number of employees in a certain sector, added value in the manufacturing segment, number of researchers in the group of countries, 3-year state budget exceeding the public debt, fossil fuel reserves, etc. The assessment showed that the share of the Greater Eurasian space in the global gross domestic product, natural rent, industry (including high-tech), patent generation, investments, freight traffic, significantly increased in 2000–2021. The most significant contributions to the development of the Greater Eurasian space are: land, transport infrastructure, budget safety from the EAEU; labour, land, GDP from countries except China; labour, production capacity, transport infrastructure, technology, international reserves from China. Such resource allocation strengthens cooperation within the GES, which is necessary to develop, introduce and promote advanced production technologies. Research results can be used to choose mechanisms and tools of international economic cooperation, as well as to simulate the movement of goods, services and production factors between the GES countries.

ASSESSMENT OF AGROBIOMAS POTENTIAL OF AGRICULTURE OF UKRAINE FOR THE PRODUCTION OF BIOFUELS

The need to develop the potential of agrobiomass for the production of biofuels is justified, which will make it possible to partially ensure the energy security of the state in the conditions of martial law. The volumes of cultivation of the main agricultural crops and the number of livestock in the field of livestock breeding in Ukraine were determined. The structure of the use of fuel and energy resources in the agro-industrial sector of the country was analyzed and the possibility of replacing oil products in the general energy balance with biodiesel and bioethanol was established. It was determined that the volume of rapeseed production in 2022 has increased by 12.9% compared to the previous year, and the increase in the price of gas oil and disruption of the logistics chains of the export of agricultural products determines the economic feasibility of processing this crop. It has been proven that the use of advanced biogas production technologies will make it possible to increase the level of environmental security of the state, optimize the content of humus in the soil due to the use of digestate, and increase the level of energy security of the state. It was determined that the total consumption of fuel and energy resources by agro-industrial complex formations in Ukraine amounted to 3.84 million tons of equivalent fuel or 2.69 million toe, and the total consumption of these resources was 86.4 million toe. It was established that the consumption of energy resources by agro-industrial complex enterprises was only 3.1% of the total consumption. It was determined that using the potential of agro-biomass of the agricultural industry will make it possible to annually obtain: 3.444 billion m3 of biogas, 1.2 million tons of biodiesel, 10.4 million tons of bioethanol, and 1.59 billion tons of solid biofuels from post-harvest residues. It has been established that the use of the energy potential of the agricultural sector will make it possible to almost completely meet the needs of not only this sector of the economy, but also the entire country in gas oil due to the production of biofuel, and the potential of bioethanol production can be partially used for export. The need to develop biofuel production at both agro-industrial complex enterprises and households has been identified. It has been proven that the use of the advanced technologies for transporting liquid digestate and injecting it will reduce the costs of agricultural formations and increase the content of humus in the soil.

Regional economic disproportions and sustainability of regional economic systems under the 2022 sanctions

In the current economic and political environment, the primary task is to strive for technological independence and self-sufficiency of the economy with maximum reliance on its own resources in development, while not excluding economic expansion by increasing competitiveness of the economy in global market. The key competitive factor is innovativeness of products and services, as well as the degree of the most advanced production technologies implementation, which together have a decisive impact on the economy efficiency in both external and domestic markets. The widespread development of globalization trends, digitalization, modern means of communication, the territorial factor importance are replaced by the factors of technological, scientific, and innovative development. In this regard, it is an urgent task to study these processes and search for factors affecting the qualitative growth of processes and manufactured products efficiency. In the present study, using mathematical and statistical methods, it has been established that the decisive value for the economy efficiency on a national scale is the value of expenditures on research and development and experimental-construction works. This indicator has a direct impact on innovation processes both in the country as a whole and in individual regions. However, one of the significant obstacles in development and sustainability of regional economies is hyperconcentration of scientific expenditures in a few regions that has a negative impact on regional development efficiency.

The results indicate that garlic production exhibits a less sustainable status across multiple dimensions. The identification of leverage variables, suggested interventions involve the following measures; enhancing irrigation systems and minimizing reliance on chemical fertilizers, providing price and marketing guarantees, reducing farmers’ dependency on subsidies, expanding the cultivated land through the application of advanced technologies for mass production of superior seeds, strengthening the involvement of agricultural extension officers, fostering consumer preferences and farmers’ engagement in garlic cultivation.

Scientific examination and study of the Qijia culture bronze artifacts from Mogou site in Lintan, Gansu

Abstract The Mogou site in Lintan, Gansu, has yielded the largest collection of Qijia culture bronze artifacts discovered to date. More than 300 bronze artifacts were unearthed, including new forms such as bracelets, neck ornaments, and earrings with trumpet-shaped ends, reflecting the advanced bronze production technology during the late Qijia culture period. This paper presents an analysis of 146 bronze artifacts from the Mogou site, conducted through metallographic microscopy and SEM-EDS analysis. Our results indicate that a relatively high percentage of small ornaments, primarily made of tin bronze, underwent hot forging and cold working, while tools, primarily made of copper and tin-bronze, were typically cast. Furthermore, this study reveals the concurrent existence of leaded tin bronze and arsenical bronze during the late Qijia culture period, suggesting influences from multiple metallurgical systems.

Acceleration of enterprise digital transformation processes based on the two-level digital maturity assessment model

In modern conditions, the main factors of breakthrough development are competition by business models and the speed of decision-making. An enterprise is more efficient if it has a business model that is more adequate to the current level of development of advanced production technologies. The aim of the work is to form a modified model for assessing the digital maturity of an industrial enterprise, ensuring the acceleration of its digital transformation. A two-level model for assessing the digital maturity of industrial enterprises is proposed, which has a modular architecture and combines a top-level module for assessing the maturity of an enterprise and its management system and a lower-level module for identifying the level of digital maturity of the main, auxiliary business processes and technological solutions of the enterprise. The model is based on the use of qualitative analysis methods and allows to identify the strengths and weaknesses of an enterprise and identify opportunities for implementing digital innovative solutions. The developed model could be used as a basis for designing self-assessment tools for an industrial enterprise in the process of developing and adapting its digital transformation strategy. The advantage of the model is a systematic analysis of heterogeneous information about the level of maturity of the enterprise and its management system, characterizing the degree of achievement of its goals, as well as information about the level of digital readiness of individual business processes and technologies of the enterprise, the assessment of which will justify the implementation of differentiated digitalization tools. The model was tested at a large machine-building enterprise in the Republic of Bashkortostan.

Development Challenges of Fruit-Harvesting Robotic Arms: A Critical Review

Promotion of research and development in advanced technology must be implemented in agriculture to increase production in the current challenging environment where the demand for manual farming is decreasing due to the unavailability of skilled labor, high cost, and shortage of labor. In the last two decades, the demand for fruit harvester technologies, i.e., mechanized harvesting, manned and unmanned aerial systems, and robotics, has increased. However, several industries are working on the development of industrial-scale production of advanced harvesting technologies at low cost, but to date, no commercial robotic arm has been developed for selective harvesting of valuable fruits and vegetables, especially within controlled strictures, i.e., greenhouse and hydroponic contexts. This research article focused on all the parameters that are responsible for the development of automated robotic arms. A broad review of the related research works from the past two decades (2000 to 2022) is discussed, including their limitations and performance. In this study, data are obtained from various sources depending on the topic and scope of the review. Some common sources of data for writing this review paper are peer-reviewed journals, book chapters, and conference proceedings from Google Scholar. The entire requirement for a fruit harvester contains a manipulator for mechanical movement, a vision system for localizing and recognizing fruit, and an end-effector for detachment purposes. Performance, in terms of harvesting time, harvesting accuracy, and detection efficiency of several developments, has been summarized in this work. It is observed that improvement in harvesting efficiency and custom design of end-effectors is the main area of interest for researchers. The harvesting efficiency of the system is increased by the implementation of optimal techniques in its vision system that can acquire low recognition error rates.

Технологический суверенитет России: понятие, измерение, возможность достижения

Geopolitical tensions, sanction conflicts, and efforts to combat the COVID-19 pandemic are amplifying the trends of deglobalization in the global economy. In response, governments of various nations and regional alliances have initiated comprehensive programs aimed at revitalizing their domestic industries and bolstering their technological independence. Despite the widespread pursuit of technological sovereignty as a strategic objective in government policies, this concept remains somewhat ambiguous and lacks clear criteria for measurement. In the contemporary context, technological sovereignty extends beyond just the development of technology; it encompasses the deployment of these technologies within national enterprises and the subsequent production of competitive goods, at the very least for domestic markets. The various methods for assessing the level of technological sovereignty can be categorized into three groups: composite indices, multi-criteria evaluations without aggregation, and individual indicators. Composite indices often face challenges when combining diverse metrics, while simpler indicators, such as foreign trade statistics or patent activity, only capture specific facets of the evaluation. Multi-criteria approach without aggregation appear to offer a more objective assessment. This study conducted a dynamic analysis of the balance between domestically sourced and imported advanced production technologies utilized by Russian enterprises, examining the share of foreign value-added in final consumption and the proportion of domestically manufactured products in the market across major sectors of the Russian manufacturing industry. The results of these calculations indicate indications of strengthening technological sovereignty, particularly in the pharmaceutical and metallurgical sectors. Sectors with relatively lower levels of technological sovereignty include machinery manufacturing, electronics, and the textile industry.
