Revealing Hidden Impact: Social and Solidarity Economy Enterprise Networks and Sustainable Development in Developing Countries

Sustainable Development, EarlyView.
ABSTRACT The Social and Solidarity Economy (SSE) offers strong potential for sustainable development in low‐income regions, yet its enterprises often operate with scarce resources, weak monitoring systems, and limited visibility. These constraints hinder both their capacity to demonstrate contributions to sustainable development (SD) and their own ...

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

steel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Computer Modeling of the Ferrite‐To‐Austenite Transformation in a Super‐Duplex Stainless Steel and the Important Role of Trans‐Interface Diffusion

steel research international, EarlyView.
An accurate moving boundary model for volume diffusion containing boundary conditions from trans‐interface diffusion (TID) simulates the austenite growth during cooling. TID of Cr, Mo, N and Ni enhance growth kinetics. Without TID, compositions of the interface region change, decreasing the driving force for growth and finally causing numerical ...

Revisiting the Association of Pesticide Exposure and Parkinson's Disease: Systematic Review and Meta‐Analysis

Environmental Toxicology, EarlyView.
ABSTRACT The association between pesticide exposure and Parkinson's disease (PD) is substantial, but heterogeneity in methodology and lack of categorization according to the type of exposure and pesticide classes in previous meta‐analyses impair the interpretation of data. This study aims to update evidence of the association between pesticide exposure

Taxon, Arboreality, Sex, and Season—Factors Influencing Gastrointestinal Parasite Occurrence in Zoo‐Housed Non‐Human Primates

Zoo Biology, EarlyView.
ABSTRACT The emergence of anthelminthic resistance is a well‐documented phenomenon in livestock and companion animals. Given the scarcity of new antiparasitic drugs, the implementation of effective, holistic anthelminthic control strategies is critical to preserving the efficacy of existing treatments.

Activating community co‐ownership of work‐related mental health: Enhancing capacity to reach at‐risk groups

Australian Journal of Public Administration, EarlyView.
Abstract Reaching and engaging workers who are reluctant, unwilling, or unable to access relevant information and timely support through their workplace or mainstream avenues is a critical policy issue in Australia and worldwide. Cross‐sector alliances between community organisations, statutory bodies, and healthcare providers can expand the reach of ...
