Security Shaping Sustainability: The Difference Between Securitized and Community‐Based Conservation in Benin

Sustainable Development, EarlyView.
ABSTRACT As global conservation efforts intensify, balancing environmental protection with social sustainability has become increasingly urgent. This study employs a comparative case study approach to examine two natural resource management interventions in northern Benin: one led by African Parks in an insecure zone, and another by TMG Research in a ...

INVESTIGATION OF GEARS WITH ASYMMETRIC PROFILE USING RELIABILITY PARAMETERS

Ukrainian Journal of Mechanical Engineering and Materials Science
The results of the study of gears with involute and sinusoidal teeth are presented herein. The subjects of the comparative analysis were the stresses at the root of the tooth from the side of the applied load and from the side of the unloaded profile, contact stresses, and elastic deformations under the action of a given torque.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Bridging Global Sustainability Objectives With Corporate Reporting Standards: Sustainable Development Goals Meet European Sustainability Reporting Standards

Sustainable Development, EarlyView.
ABSTRACT Given the complexity of the Sustainable Development Goals (SDGs), aligning corporate sustainability with them can be challenging. Drawing on systems thinking, this study examines how the European Sustainability Reporting Standards (ESRS) align with the SDGs and bridge macro‐level global goals with firm‐level metrics.

Motivational and Behavioural Determinants of Participation in Renewable Energy Communities

Sustainable Development, EarlyView.
ABSTRACT Renewable Energy Communities (RECs) are increasingly recognised as key instruments for supporting the energy transition, promoting citizen engagement, and enhancing the integration of renewable energy sources. However, limited evidence is available on how motivational factors and behavioural mechanisms jointly influence individuals ...

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...
