Diffusion of Characteristic Gases in Oil‐Immersed Transformer by Computational Fluid Dynamics Simulation and Experimental Verification

open access: yesHigh Voltage, EarlyView.
ABSTRACT The complex diffusion of characteristic gases within oil‐immersed transformers significantly influences the timeliness between the fault occurrence and gas detection. So far, the gas transport processes and spatio‐temporal distributions remain inadequately understood.

Endurance of Epoxy Resin Cast Insulation With Interfacial Micro‐Crack Defect Under 50 Hz Sine and Kilohertz Square Voltages

open access: yesHigh Voltage, EarlyView.
ABSTRACT Crack‐type defects are commonly found in epoxy composite cast insulation due to residual, thermal and external stresses. When combined with inverter‐type voltage stress, as in epoxy cast high‐frequency transformers (HFTs), the likelihood of insulation failure increases significantly. In this study, a method setting microcracks perpendicular to

Trait co‐occurrence networks reveal changes in community functional structure from local to landscape scales

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The functional composition of communities reflects species performance and its interplay with local and regional drivers. Yet trait‐based analyses often overlook regional heterogeneity (geographic and environmental differences among communities), despite its central ...

Chronic Disease and Disability in the United States: Trends, Inequities, and Imperatives for Policy Reform

open access: yesThe Milbank Quarterly, EarlyView.
Policy Points Position Universal, High‐Quality Education as a Foundational Public Health Strategy. Long‐term health and life expectancy in the United States are shaped more by educational attainment than by any other single factor. Disparities in access to early childhood, K‐12, and higher education perpetuate cycles of chronic disease, economic ...

Uncovering Biogas Outcomes: Tales of Hubris, Hope, and Failure From Southern Malawi

open access: yesNatural Resources Forum, EarlyView.
ABSTRACT The purpose of this article is to speak directly to biogas failure. Over the past two decades, immense amounts of money have been spent by African governments, private individuals, and most conspicuously, international aid agencies and donors, on countless biogas projects in every country on the continent.

Microplate Tectonics Through Earth History and Across Solid Multispheres

open access: yesGeological Society of China Bulletin, EarlyView.
The evolution of tectonic microplates throughout Earth´s history as well as the transitions between microplates across different solid spheres offers a novel approach to expanding the traditional plate tectonics theory. ABSTRACT The evolution of tectonic microplates throughout Earth's history as well as the transitions between microplates across ...

Climate Change Commitment: As Agency Theory Pertains to Engaging Supply Chains in Science‐Based Targets

open access: yesAccounting &Finance, EarlyView.
ABSTRACT We explore how corporates working towards valid Science‐based Targets engage with their suppliers to collect Scope 3 emissions data. This is important to enable such corporates to reduce greenhouse gas emissions and achieve net‐zero by 2050. Utilising agency theory, we analyse 1402 responses from the 2021 CDP climate change survey.

Impact of Chelators on FAC Following Interaction With NaOCl: A Focused Evidence Synthesis Based on a Systematic Search

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This systematic review following PRISMA guidelines evaluated the effects of endodontic chelators on free available chlorine (FAC) in sodium hypochlorite (NaOCl), with emphasis on the influence of concentration, contact time, temperature, and pH. Risk of bias was assessed using the Quality Assessment Tool for In Vitro Studies (QUIN).

Postcode‐Level Variation and Environmental Determinants of Respiratory Allergies in a Large German Cohort

open access: yesAllergy, EarlyView.
Young children (0–9 years) and residents of urban areas appeared particularly vulnerable to respiratory allergy development and exacerbation. Incidence showed nonlinear associations with PM10, PM2.5, temperature, and alder/birch pollen, while DPMR showed similar patterns, except for NO2 and the interaction O3*NO2.

Hair Degradation Patterns in Aquatic and Soil Environments

open access: yesArchaeometry, EarlyView.
ABSTRACT Hair is a biological material that can provide information in archaeology and forensics. Previous studies have mainly examined changes occurring post‐mortem. In this study, we focused on hair pulled out ante‐mortem. The aim of the study was to identify patterns in the degradation of hair in water and soil.
