Important barriers to the use of QALYs in the United States include concerns about disability and age discrimination.Modifications to the utility function underlying QALYs have been proposed to mitigate these concerns, but some find them challenging to consider and/or to apply.Unrelated to these concerns, QALYs have been adapted within the framework of distributional cost-effectiveness analysis to allow consideration of inequality as well as efficiency.I outline how this framework can also remediate concerns about disability and age discrimination.

Per- and polyfluoroalkyl substances (PFASs) have recently garnered considerable concerns regarding their impacts on human and ecological health. Despite the important roles of polyamide membranes in remediating PFASs-contaminated water, the governing factors influencing PFAS transport across these membranes remain elusive. In this study, we investigate PFAS rejection by polyamide membranes using two machine learning (ML) models, namely XGBoost and multimodal transformer models.

Increasing antimony (Sb) pollution has become a global concern, but there is still a lack of economically efficient adsorbents for its remediation. In this study, a novel remediation material was developed by precipitating TiO onto waste herb-residue biochar (named TBC). The effectiveness and adsorption mechanisms of the material for Sb(III) removal were investigated through adsorption experiments, and the enhancement pathway of traditional herb decoction on the effectiveness of modified biochar was analyzed.

Treatment wetlands have emerged as a potential remediation option for oil-sands process affected waters (OSPW) which contains a suite of organic and inorganic constituents of potential concern. The aim of this study was to evaluate the fate of metals in a treatment wetland exposed to OSPW. Data was collected over three operational seasons testing freshwater and OSPW inputs at the Kearl Treatment Wetland in northern Alberta.

Contemporary medical science has been using fat grafting in aesthetic and reconstructive procedures, consistently achieving successful outcomes. Hansen's disease, caused by , leads to hand deformities due to peripheral neuropathy, resulting in soft-tissue atrophy, volume loss, and compromised hand function. Tendon transfer surgery is a common remedy for functionality, but it often does not address aesthetic concerns and the patient's psychological impact of living with an atrophic hand.

Organoarsenicals are toxic pollutants of global concern, and their environmental geochemical behavior might be greatly controlled by iron (Fe) (hydr)oxides through coprecipitation, which is rarely investigated. Here, the effects of the incorporation of dimethylarsenate (DMAs(V)), a typical organoarsenical, into the ferrihydrite (Fh) structure on the mineral physicochemical properties and Fe(II)-induced phase transformation of DMAs(V)-Fh coprecipitates with As/Fe molar ratios up to 0.0876±0.
