Green Technology Innovation, Capital-Factor Allocation, and Manufacturing-Export Resilience
Authors: Liu Xiangxia , Liu Shen
Published: February 2024

Green technology innovation, with its two-fold benefits of protecting the environment and promoting economic growth, is an increasingly necessary strategy for China’s manufacturing exports. This study examines the impact and mechanisms of green technology innovation on China’s manufacturing-export resilience in the aftermath of the 2008 global financial crisis. The study findings demonstrate that green technology innovation considerably boosts manufacturing-export resilience. Specifically, green technology innovation enhances manufacturing-export resilience by improving capital allocation efficiency. This is especially significant in the high labour-mismatch region and the eastern–central region. It is worth noting that the impact of green technology innovation on manufacturing-export resilience is negatively regulated by intellectual-property protection, as well as being subject to the single-threshold effect of government intervention. That is, reinforcing intellectual-property protection inhibits the upgrading effect of green technology innovation on manufacturing-export resilience, and the effect of green technology innovation on manufacturing-export resilience becomes insignificant when the government intervention goes beyond a certain level.

Published: February 2024

This paper aims to study the required solar panel tilt angle, area, and investment payback period for achieving zero-energy heating in historically significant courtyard-style residential buildings. The retrofitting approach involves positioning solar panels on the main building of the structure using four supports, each located at the corners, elevated from the ground and not in direct contact with the building. This approach does not alter the external envelope structure of the building, thereby preserving the authenticity of the cultural heritage. Using BESI software, we simulated the heating energy demand of the sample building. We integrated a solar heating system within the building and analyzed the optimal solar panel layout area, installation angle, and payback period for achieving zero-energy heating. This allowed the building to meet the zero-energy heating requirements. Taking the Hu Family Courtyard heritage conservation building as an example, we proposed the optimal layout plan for solar energy retrofitting.

Published: February 2024

Smart cities, as defined by Sustainable Development Goal 11, strive to make cities more inclusive, safe, resilient, and sustainable. Digital technologies addresses urbanisation concerns, such as rising energy use, pollution, waste disposal, and social inequities. The Internet of Things (IoT) and data-driven technologies are essential drivers, with a focus on infrastructure and decision-making in smart cities and municipalities. Digital Transformation (DT) is a prerequisite for becoming a Smart Municipality. The research objective of this paper is to investigate the role of digital technologies in improving urban processes, focusing on Smart City dimensions for municipalities, namely smart governance, environment, living, and technology. Municipalities in South Africa, particularly in the Eastern Cape, used digital adoption to boost productivity and skill development. However, the need for standardised DT principles presents problems for transitioning municipalities into data-driven organisations. The paper also examines the global energy issue and how smart cities can contribute to energy solutions. Finally, the paper addresses the following research question: ‘How can lessons learned from the Eastern Cape Municipalities digital adoption be scaled to other developing nations facing similar challenges in energy management and urban planning?’ Using a survey method, it provides guidelines in the DT framework, offering empirical insights into Smart Municipality digitalisation.
What You Get Is What You See—The Mutual Relationships between Images of Human Nature and Business Model Innovation
Authors: Hausdorf Michaela
Published: February 2024

Despite considerable scholarly interest in the drivers of and barriers to business model innovation for sustainability transformations, scholars have not yet explored the role of images of human nature in this context. This is surprising because economic decisions are profoundly shaped by assumptions about humanity and its role in the world. Applying conceptual modelling as a methodological approach, this article sheds light on the mutual relationships between images of human nature and business model innovation. The main insights are twofold: First, images of human nature can be drivers of or barriers to business model innovation, as they enable or obstruct the adoption of new business models. Second, images of human nature can be challenged and adjusted through practical experiences with business models. The article concludes that images of human nature as representing an evolving holon have the greatest potential to push forward sustainability transformation by understanding humanity in a post-anthropocentric way and facilitating a profound reconsideration of business and economy. This study contributes to research on business model innovation by answering recent calls to advance theoretical perspectives on the factors that influence decision-making in innovation processes. It also helps research and practice to understand why certain business model innovations are preferred over others.

Published: February 2024

The adoption of e-government promises efficiency in the delivery of government services to citizens across various sectors of the economy. Due to this, most Global North countries have advanced in the deployment of e-government for improving public-service delivery. Unfortunately, most African countries, including Ghana, are still lagging in e-government development. This study examined e-government development across African Union member states. It explored the role of e-government in the reform of public administration and governance, focusing on Ghana as a case study. Using a mixed-method approach, the study analyzed secondary data of key e-government indicators using the TOPSIS method. This helped underscore the transformative impact on public administration and governance by using primary data via interviews. The results show advanced progress in some African countries, including Ghana, due to aligned digital strategies with national policies. Also, technology integration is evident in Ghana’s public sector and is reshaping public administration and governance. The study recommends that to achieve the long-term sustainability of these advancements, interagency collaboration and data-sharing mechanisms between the public and private sectors should be strengthened, while all forms of silos should be broken to promote the delivery of services. This study enhances public-service delivery by identifying areas needing both improvement and allocation of resources for shaping e-government policy development.

Published: February 2024

Artificial intelligence (AI) is advancing across technology domains including healthcare, commerce, the economy, the environment, cybersecurity, transportation, etc. AI will transform healthcare systems, bringing profound changes to diagnosis, treatment, patient care, data, medicines, devices, etc. However, AI in healthcare introduces entirely new categories of risk for assessment, management, and communication. For this topic, the framing of conventional risk and decision analyses is ongoing. This paper introduces a method to quantify risk as the disruption of the order of AI initiatives in healthcare systems, aiming to find the scenarios that are most and least disruptive to system order. This novel approach addresses scenarios that bring about a re-ordering of initiatives in each of the following three characteristic layers: purpose, structure, and function. In each layer, the following model elements are identified: 1. Typical research and development initiatives in healthcare. 2. The ordering criteria of the initiatives. 3. Emergent conditions and scenarios that could influence the ordering of the AI initiatives. This approach is a manifold accounting of the scenarios that could contribute to the risk associated with AI in healthcare. Recognizing the context-specific nature of risks and highlighting the role of human in the loop, this study identifies scenario s.06—non-interpretable AI and lack of human–AI communications—as the most disruptive across all three layers of healthcare systems. This finding suggests that AI transparency solutions primarily target domain experts, a reasonable inclination given the significance of “high-stakes” AI systems, particularly in healthcare. Future work should connect this approach with decision analysis and quantifying the value of information. Future work will explore the disruptions of system order in additional layers of the healthcare system, including the environment, boundary, interconnections, workforce, facilities, supply chains, and others.

Surveying Quality Management Methodologies in Wooden Furniture Production
Authors: Skorupińska Ewa , Hitka Miloš , Sydor Maciej
Published: February 2024

Furniture production is a specific industrial sector with a high human labor demand, a wide range of materials processed, and short production runs caused by high customization of end products. The difficulty of measuring the aesthetic requirements of customers is also specific to furniture. This review of academic papers identifies and explains effective quality management strategies in furniture production. The reviewed literature highlights a range of quality management methodologies, including concurrent engineering (CE), total quality management (TQM), lean manufacturing, lean six sigma, and kaizen. These strategies encompass a variety of pro-quality tools, such as 5S, statistical process control (SPC), quality function deployment (QFD), and failure mode and effects analysis (FMEA). The strengths of these quality management strategies lie in their ability to enhance efficiency, reduce waste, increase product diversity, and improve product quality. However, the weaknesses concern implementation challenges and the need for culture change within organizations. Successful quality management in furniture production requires tailoring strategies to the specific context of the furniture production industry. Additionally, the importance of sustainability in the furniture industry is emphasized, which entails incorporating circular economy principles and resource-efficient practices. The most important finding from the literature analysis is that early detection and correction of poor quality yields the most beneficial outcomes for the manufacturer. Therefore, it is essential to strengthen the rigor of quality testing and analysis during the early stages of product development. Consequently, a deep understanding of consumer perspectives on required furniture quality is crucial. The review identified two research gaps: (1) the impact of unnecessary product over-quality on the efficiency of furniture production and (2) the influence of replacing CAD drawings with a model-based definition (MBD) format on quality management in furniture production.

Authors: Slavina Tomislav , Štefanić Nedeljko
Published: February 2024

Manufacturing companies are always looking for ways to outperform their competitors. They are constantly trying to improve their efficiency and reduce costs. One method that improves efficiency and maximises the availability of production equipment is total productive maintenance (TPM), which is a lean optimisation philosophy tool that focuses on the optimisation of maintenance. Although TPM is known for improving maintenance, there are many obstacles to its successful implementation. Failure to properly implement TPM can result in additional costs and lost time, and it can have a negative impact on employees. For these reasons, a survey was prepared and conducted among several companies, each involved in a different field of work and having a different number of employees. The main findings of this research are the key factors that can negatively impact the implementation of TPM and lean tools in general, as well as suggestions for improvements that can ensure their successful implementation and sustainability. An analysis was conducted based on the size of each company as well as the job roles within them. The study covers issues that may arise during the implementation of TPM and other lean tools at all levels of the hierarchy in an enterprise and provides guidance on how to manage situations that may prevent the successful application of TPM.

Published: February 2024

In the realm of clinical practice, nucleoside analogs are the prevailing antiviral drugs employed to combat feline herpesvirus-1 (FHV-1) infections. However, these drugs, initially formulated for herpes simplex virus (HSV) infections, operate through a singular mechanism and are susceptible to the emergence of drug resistance. These challenges underscore the imperative to innovate and develop alternative antiviral medications featuring unique mechanisms of action, such as viral entry inhibitors. This research endeavors to address this pressing need. Utilizing Bio-layer interferometry (BLI), we meticulously screened drugs to identify natural compounds exhibiting high binding affinity for the herpesvirus functional protein envelope glycoprotein B (gB). The selected drugs underwent a rigorous assessment to gauge their antiviral activity against feline herpesvirus-1 (FHV-1) and to elucidate their mode of action. Our findings unequivocally demonstrated that Saikosaponin B2, Punicalin, and Punicalagin displayed robust antiviral efficacy against FHV-1 at concentrations devoid of cytotoxicity. Specifically, these compounds, Saikosaponin B2, Punicalin, and Punicalagin, are effective in exerting their antiviral effects in the early stages of viral infection without compromising the integrity of the viral particle. Considering the potency and efficacy exhibited by Saikosaponin B2, Punicalin, and Punicalagin in impeding the early entry of FHV-1, it is foreseeable that their chemical structures will be further explored and developed as promising antiviral agents against FHV-1 infection.
The C4 Protein of TbLCYnV Promotes SnRK1 β2 Degradation Via the Autophagy Pathway to Enhance Viral Infection in N. benthamiana
Authors: Li Xinquan , Zhao Min , Yang Wanyi , Zhou Xueping , Xie Yan
Published: February 2024

Geminiviruses are a group of single-stranded DNA viruses that have developed multiple strategies to overcome host defenses and establish viral infections. Sucrose nonfermenting-1-related kinase 1 (SnRK1) is a key regulator of energy balance in plants and plays an important role in plant development and immune defenses. As a heterotrimeric complex, SnRK1 is composed of a catalytic subunit α (SnRK1 α) and two regulatory subunits, β and γ. Previous studies on SnRK1 in plant defenses against microbial pathogens have mainly focused on SnRK1 α. In this study, we validated the interaction between the C4 protein encoded by tobacco leaf curl Yunnan virus (TbLCYnV) and the regulatory subunit β of Nicotiana benthamiana SnRK1, i.e., NbSnRK1 β2, and identified that the Asp22 of C4 is critical for TbLCYnV C4–NbSnRK1 β2 interactions. NbSnRK1 β2 silencing in N. benthamiana enhances susceptibility to TbLCYnV infection. Plants infected with viral mutant TbLCYnV (C4D22A), which contains the mutant version C4 (D22A) that is incapable of interacting with NbSnRK1 β2, display milder symptoms and lower viral accumulation. Furthermore, we discovered that C4 promotes NbSnRK1 β2 degradation via the autophagy pathway. We herein propose a model by which the geminivirus C4 protein causes NbSnRK1 β2 degradation via the TbLCYnV C4–NbSnRK1 β2 interaction to antagonize host antiviral defenses and facilitates viral infection and symptom development in N. benthamiana.
Role of Viral Envelope Proteins in Determining Susceptibility of Viruses to IFITM Proteins
Authors: Marceau Thomas , Braibant Martine
Published: February 2024

Interferon-induced transmembrane proteins (IFITMs) are a family of proteins which inhibit infections of various enveloped viruses. While their general mechanism of inhibition seems to be non-specific, involving the tightening of membrane structures to prevent fusion between the viral envelope and cell membrane, numerous studies have underscored the importance of viral envelope proteins in determining the susceptibility of viruses to IFITMs. Mutations in envelope proteins may lead to viral escape from direct interaction with IFITM proteins or result in indirect resistance by modifying the viral entry pathway, allowing the virus to modulate its exposure to IFITMs. In a broader context, the nature of viral envelope proteins and their interaction with IFITMs can play a crucial role in the context of adaptive immunity, leading to viral envelope proteins that are more susceptible to antibody neutralization. The precise mechanisms underlying these observations remain unclear, and further studies in this field could contribute to a better understanding of how IFITMs control viral infections.

Published: February 2024

In South China, due to climatic factors, highly weathered granite is distributed across a large area and easily disintegrates after encountering water, causing many geological disasters and other problems. To determine the disintegration mechanism of highly weathered granite in South China, disintegration tests were carried out on highly weathered granite in the Fuzhou area under different immersion durations, cycle times, and flow rates, with the help of a self-designed disintegration test device. Moreover, the disintegration mechanism of the highly weathered granite was revealed using nuclear magnetic resonance (NMR) technology. The results demonstrated an increase in the cumulative relative disintegration with prolonged immersion time and the number of dry-wet cycles. Beyond a certain flow rate, the cumulative relative disintegration amount stabilized. There was a strong correlation between the steady disintegration rate and immersion time (or dry-wet cycles). The disintegration process of the highly weathered granite was divided into three stages: rapid, moderate, and stable disintegration. Notably, disintegration primarily occurred around the large pores. This study revealed that the variation in the immersion time (or wet-dry-scouring cycles) was fundamentally linked to changes in the relative volume of the large pores in the rock samples. These findings provide valuable insights for predicting and mitigating surface disasters on highly weathered granite slopes.

Published: February 2024

Nowadays, electric vehicles have gained significant attention as a promising solution to the environmental concerns associated with traditional combustion engine vehicles. With the increasing demand for high-performance hypercars, the need for advanced torque control strategies has become paramount. Field-Oriented Control using Current Vector Control represents a consolidated solution to implement torque control. However, this kind of control must take into account the DC link voltage variation and the variation of motor parameters depending on the magnets’ temperature while providing the maximum torque production for specific inverter current and voltage limitations. Multidimensional lookup tables are needed to provide a robust torque control from zero speed up to maximum speed under deep flux-weakening operation. Therefore, this article aims to explore the application of FOC 4D control in electrical hypercars and its impact on enhancing their overall performance and control stability. The article will delve into the principles underlying FOC 4D control and its advantages, challenges, and potential solutions to optimize the operation of electric hypercars. An electric powertrain model has been developed in the Simulink environment with the Simscape tool using a S-function block for the implementation of digital control in C-code. High-power electric motor electromagnetic parameters, derived from a Finite Element Method magnetic model, have been used in the simulation. The 4D LUTs have been computed from the motor flux maps and implemented in C-code in the S-function. The choice of FOC 4D control has been validated in the main load points of a hypercar application and compared to the conventional FOC. The final part of the research underlines the benefits of the FOC 4D on reliability, critical in motorsport applications.

A comparison was made of the numerical indicators of zooplankton and zoobenthos of the Chulym River in comparison with those obtained in 1972–1973 in order to assess the transformation of the ecosystem that has occurred over 50 years. It is shown that the zooplankton of the Chulym River has undergone dramatic changes, both qualitatively and quantitatively. The number of zooplankton increased 4–5 times due to small rotifers. At the same time, the zooplankton biomass, and therefore the feed value, decreased by more than half due to a reduction in the number of large crustaceans. The species composition of structure-forming zooplankton species has changed. The number of rotifer species in the riverbed decreased from 55 rotifers to 34. The species of Trichocerca family dropped out of the dominant composition and representatives of the river began to dominate Brachionus family. There is a significant change in the structure of zoobenthos: the number of organisms in the Chulym River bed is 5 times lower than in the 1970s. The species composition in benthic communities has remained almost unchanged over 50 years, while the proportion of some heterotopic insects (caddis flies, mayflies, stoneflies) has increased, and the proportion of oligochaetes, mollusks and chironomids in the biomass has decreased by 4–5 times. In the accessory reservoirs of Chulym, the abundance and biomass of zooplankton and zoobenthos over the past 50 years have remained more or less stable, which may indicate the presence of chronic pollution that affects the ecosystem of the main river channel and does not have time to have a negative impact on the accessory reservoirs during floods. The water quality indicators of the Chulym River and its subsidiary reservoirs, according to biotic indices, are low and correspond to a low or poor water quality class. Such conditions are unfavorable for the further development of zoobenthos and, accordingly, ichthyofauna, for which bottom invertebrates are the food supply.

It is generally accepted that water intake facilities used in fishery reservoirs adversely affect the state of fish stocks — a large number of juvenile fish fall into them along with water. The study of environmental factors, hydrological conditions and design solutions affecting the effectiveness of fish-protection structures (devices) such as umbrella installed on bottom water intakes in the form of suction or gravity pipes of pumping stations is of great importance for preventing the death of juvenile fish. Studies of the effectiveness of umbrella fish-protection devices were carried out in 2020–2022 at two water intake facilities located on the Irtysh River within the boundaries of the Omsk Region. Field studies at each water intake were carried out during four calendar seasons (spring, summer, autumn, winter). The collection of materials on the species, size and quantitative composition of larvae and juveniles of fish was carried out before the fish-protection installation, in coastal wells and near the shore in the area of water intake to study the background state of the concentration of juvenile fish around the clock with an interval of 4 hours. Juveniles and larvae of fish in the area of water intake were localized exclusively along the coast, where they were caught. Juveniles and larvae of fish were not recorded at other fishing points. Studies have shown that the location of the water intake umbrella heads in a place remote from the shore, where the larvae and juveniles of fish are practically not found, as well as the low flow rate in the water intake devices, ensure high efficiency of fish-protection devices of channel water intakes.

Sarcopenia, defined as age-related decline in skeletal muscle mass and functional capacity, is a hallmark nutritional abnormality observed in patients with moderate-to-advanced CKD. Uremic state and associated medical conditions also predispose older patients with CKD to protein–energy wasting, a nutritional abnormality that could include sarcopenia. Prevention of protein and energy depletion and replenishing the already low nutritional reserves elderly patients with CKD should focus on conventional and innovative strategies. This review aims to provide an overview of the mainstay of nutritional therapy in this patient population, such as intake of adequate amounts of protein and energy along with preserving fluid, electrolyte, and mineral balance, and to discuss more innovative interventions to aid these approaches.
Una independencia a la altura de un gran país - Paraguay en su proceso de independencia
Authors: García Antonio Delgado
Published: February 2024

Los procesos de independencia en Hispano América, vienen precedidos de toda una serie de sucesos históricos en la Península Ibérica en los momentos de la supremacía napoleónica en Europa y en su repercusión en la sede y la corona de la Monarquía Hispánica. De todos los países que surgirían a lo largo de las décadas de 1810 y 1820, es el Paraguay el pionero en su gestación independiente, pero en un proceso que le hace antes independizarse de las regiones limítrofes y su influencia como la ejercida desde Buenos Aires, que no tanto de Madrid tan lejana y distante de quien se independizará por el progresivo aislamiento y la condición de mediterraneidad del Paraguay en el corazón sudamericano.

Afetler sonrası kentlerin planlanması hem sosyal altyapı alanları açısından önemli eksiklikleri bulunan hem de afetler karşısından riskler taşıyan kentsel bölgelerin yenilenmesinde, daha nitelikli ve yaşam kalitesi yüksek kentsel mekânları oluşturma, risk azaltma, fiziksel kapasitenin artırılması ve kentsel dirençlilik açısından fırsatlar taşımaktadır. Afet yönetiminin başarısı, afet sonrasında iyileştirme aşamasında yapılan uygulamaların risk azaltma aşamasına katkı sağlaması noktasında ortaya çıkmaktadır. Başka bir ifadeyle, afet öncesinde olası risklerin minimize edilebilmesi ve/veya bertaraf edilebilmesi afet yönetim sürecinin başarılı bir biçimde yürütüldüğünün önemi bir göstergesidir. Bu kapsamda çalışma afet risklerinin azaltılması açısından büyük önem taşıyan ve toplanma alanı olma potansiyeli taşıyan sosyal altyapı alanlarının mekânsal dağılımı ve kapasiteleri açısından yeterliliğini incelemeyi amaçlamaktadır. Bu amaç doğrultusunda, 30 Ekim 2020 tarihinde gerçekleşen Ege Denizi depreminden en çok etkilenen İzmir İli Bayraklı İlçesi’nde yer alan sosyal altyapı alanları çalışma alanı olarak belirlenmiştir. Yapılan incelemeler ışığında, Bayraklı İlçesinde yer alan 24 mahallenin 16 tanesi (%67) kapasite bakımından yeterli olduğu, kalan 8 mahallenin (%33) ise yetersiz olduğu saptanmıştır. Ayrıca, Bayraklı İlçesi’nde potansiyel toplanma alanlarının ilçenin %62’sine hizmet verdiği, bu bakımdan ilçenin diğer ilçelere göre iyi durumda olduğu ve potansiyel toplanma alanlarının ilçe genelinde daha homojen dağıldığı tespit edilmiştir. Dolayısıyla, Ekim 2020 döneminde gerçekleşen deprem sonrasında Bayraklı İlçesi genelinde yer alan potansiyel toplanma alanlarının ihtiyacı yeterli düzeyde karşılayamadığı anlaşılmaktadır.
