The purpose of this study is to suppress the temperature rise of high voltage wall bushing metal plate.

First, the authors built a model of a traditional metal plate and got the magnetic field intensity distribution by FEA tools. Optimized according to the magnetic field intensity distribution, the authors slot the traditional metal plate and embed permanent magnets in the slot. Finally, the authors got the temperature distribution diagrams of the above three cases at different current levels by FEA tools.

Slotted metal plate is beneficial to suppress magnetic induction intensity, but the improvement of the magnetic induction intensity uniformity is not obvious. The method of embedding a permanent magnet in a slotted metal plate can optimize the magnitude and uniformity of the magnetic induction intensity in the metal plate. The larger the current passing through the metal plate, the better the temperature suppression effect of the slotted metal plate and the slotted metal plate embedded in the permanent magnet.

The effect of structural factors, slotting plate and setting permanent magnets on slots on the temperature of supporting plate is studied. The paper proposes two methods, slotting metal panels and embedding permanent magnet metal panels, to solve the problems of eddy current loss and high calorific value of the panel, which is of great significance to the safety of the grid equipment.

Purpose: Sustainable and responsible business is strongly associated with activities that minimise negative environmental or social impacts. As a result, the utility of big data is becoming a reality, opening up exciting possibilities for ESG monitoring and assessment. This study systematises existing knowledge and provides recommendations for big data in ESG monitoring and assessment.

Methodology/approach: Theoretical and exploratory focusing on a literature review.

Conclusions: Results indicate different levels of progress and challenges related to ESG and big data. Awareness and adoption of ESG and big data practices is growing, accompanied by regulatory pressure.

Significance: Understanding the relationship between big data and ESG is critical to properly conducting sustainable and responsible business practices. The urgency and necessity of developing standards for constructing big data cannot be overstated for ensuring consistency between existing policies and the SDGs and for the effective use of big data in ESG monitoring and assessment.

Limitations: A lack of data quality and standardisation in reporting for ESG assessments. Standardisation efforts are growing as data challenges, especially data availability, are major constraints. Large data sets offer exciting opportunities, analysed mainly from the perspective of existing applications for measuring sustainability goals.

Future research: An in-depth analysis of case studies that combine ESG issues with big data infrastructure. Fundamental is knowledge and understanding of companies’ ESG practices and understanding big data issues. We can standardise approaches to using new data sources and move towards deepening our measurable dimension of sustainability assessment.

The mechanical and tribological properties of polymers and polymer composites vary with different environmental conditions. This paper aims to review the influence of humidity/water conditions on various polymers and polymer composites' mechanical properties and tribological behaviors.

The influence of humidity and water absorption on mechanical and tribological properties of various polymers, fillers and composites has been discussed in this paper. Tensile strength, modulus, yield strength, impact strength, COF and wear rates of polymer composites are compared for different environmental conditions. The interaction between the water molecules and hydrophobic polymers is also represented.

Pure polymer matrices show somewhat mixed behavior in humid environments. Absorbed moisture generally plasticizes the epoxies and polyamides and lowers the tensile strength, yield strength and modulus. Wear rates of PVC generally decrease in humid environments, while for polyamides, it increases. Fillers like graphite and boron-based compounds exhibit low COF, while MoS2 particulate fillers exhibit higher COF at high humidity and water conditions. The mechanical properties of fiber-reinforced polymer composites tend to decrease as the rate of humidity increases while the wear rates of fiber-reinforced polymer composites show somewhat mixed behavior. Particulate fillers like metals and advanced ceramics reinforced polymer composites exhibit low COF and wear rates as the rate of humidity increases.

The mechanical and tribological properties of polymers and polymer composites vary with the humidity value present in the environment. In dry conditions, wear loss is determined by the hardness of the contacting surfaces, which may not effectively work for high humid environments. The tribological performance of composite constituents, i.e. matrix and fillers in humid environments, defines the overall performance of polymer composite in said environments.

The purpose of this study is to review the development of the socially sustainable supply chain management field.

The 112 most cited papers in the field until 2017 are analysed using a state-of-the-art structured literature review model borrowed from the accounting field.

This study highlights the increasing number of publications across the years, the diversity of journals and the type of authors addressing the topic. It reveals that qualitative studies focused on large companies in the garment, food and electronics sectors and on private regulations capture most of the attention, with Asia, Europe and North America being the most scrutinised locations. Drivers and barriers for socially sustainable supply chain management are summarised, clustered and confronted. This study also evaluates how the sustainability and corporate social responsibility concepts are used in the above field and analyses the existing definitions of social sustainability.

This study incites researchers to broaden their studies to diverse sectors and locations, addressing different levels of supply chains with quantitative techniques and clearer conceptual foundations.

This study incites practitioners to further contribute to this scholars-dominated research field, offering their practical insights and perspectives.

This study offers original insights and critiques of the literature, highlighting its gaps and proposing new research avenues for the future.
