Extended Producer Responsibility (EPR) places liability, physical, financial, and/or informative responsibility for a product throughout its life cycle on its producer. Implementing such schemes is expected to result in many environmental and social benefits. Yet, academic and practitioner discussions on the mechanisms focus on environmental impacts, whereas social dimensions of EPR are often side-lined. This short communication contributes to addressing this gap by establishing a research agenda for the justice di [...]

This review examines the quality of the research exploring mindfulness within tai chi chuan and the way this integrative practice benefits health and learning for higher education students. A narrative review based on a systematic search was conducted. Ten English and three Chinese databases were utilised to appraise the relevant literature. The initial search identified 874 potentially appropriate English articles and 265 Chinese articles. A final review of 52 Chinese and 8 English articles was conducted. We used [...]

In this perspective on hydrogen carriers, we focus on the needs for the development of robust active catalysts for the release of H2 from aqueous formate solutions, which are non-flammable, non-toxic, thermally stable, and readily available at large scales at reasonable cost. Formate salts can be stockpiled in the solid state or dissolved in water for long term storage and transport using existing infrastructure. Furthermore, formate salts are readily regenerated at moderate pressures using the same catalyst as for [...]

The COVID-19 pandemic has lasted for more than 16 months, and there have been over 169 million confirmed cases worldwide. Besides, after treatment with Western medicine or undergoing home quarantine, COVID-19 patients are still severely or mildly functionally impaired. Though COVID-19 patients were discharged from the hospital, most of them still exhibit certain clinical symptoms such as fatigue, poor appetite, shortness of breath, and poor sleep. The syndromes, linked with the Chinese Medicine (CM) body constituti [...]

Children with cancer can experience intense suffering. Currently, despite our best efforts, symptoms associated with both cancer and its treatment result in physical, psychological, and emotional discomfort that can be difficult to manage with traditional Western medicine alone. Developing integrative services within a pediatric hematology-oncology program may help improve cancer-related symptoms by combining different modalities targeting overall health with traditional oncology care. This study details the initia [...]

Aging models are important input into wind farm maintenance and financial viability models. Aging of wind turbines depends on many factors, including both ambient and usage conditions. This paper presents a virtual age based maintenance model for wind turbines considering the effect of wind speed and ambient air temperature on turbine aging. Two maintenance thresholds (i.e., corrective threshold and preventive threshold) and three repair actions (i.e., unscheduled corrective, scheduled corrective and preventive act [...]

Islet cell transplantation is a developing treatment for patients suffering from severe Type-1 diabetes. The long-term insulin independence after islet cell transplantation has been difficult to achieve, and this has been linked to several factors. One of the major cause of poor long-term outcome is inflammation surrounding the islets. Inflammation in islets is caused at several stages, donor induced, during organ preservation, islet isolation stress, peri-transplant inflammation or instant blood mediated inflammat [...]

The use of Pd-Cu bimetallic catalysts in the reduction of aqueous nitrate ions by hydrogen was studied. The catalysts were supported on multi-walled carbon nanotubes (MWCNTs), activated carbon (AC), and Titania, and the influence of the support on the nitrate reduction activity in water was then investigated. The catalysts were characterized before and after use by FT-IR, XRD, SEM, EDX, and Laser Granulometry. It was found that the surface characteristics of the support have an influence on the catalyst activity, w [...]

Each country has its own characteristics of COVID-19 infection trajectory and epidemic waves. Differences in government-implemented restrictions and social regulations result in variability of the virus transmissions and spread dynamics. This in turn results in various shapes of the growth function used to represent and describe the propagation of infection. Statistical methods are applied to fit non-linear functions to represent daily time-series data of the cumulative numbers of COVID-19 cases. The aim of this wo [...]

Many multinational retail companies are exposed to financial risk related to climate change. Carbon management is important in keeping global temperature increases below 1.5°C to prevent the exacerbated impacts of climate change. Auchan Retail in Auchan Holding provides a good example of carbon management in the retail sector. Auchan Retail's major emissions are the indirect emissions throughout their value chain (scope 3 emissions). The total estimated emission of scopes 1, 2 and 3 are 37,822,573.9 t CO2e. [...]
