Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

Sustainable Development, EarlyView.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Information Dynamics and Learning in Complex Adaptive Systems: Toward a Transdisciplinary Framework

Systems Research and Behavioral Science, EarlyView.
ABSTRACT This article develops a framework for understanding learning and adaptation in complex adaptive systems. Drawing from neuroscience, systems theory, information theory and quantum field theory, it examines how information processing, plasticity and systemic coherence emerge from distributed, nonlinear and feedback‐driven interactions. It argues

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.

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

steel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.

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 ...
