Pelvic morphology and body size in relation to the preauricular sulcus: Evidence from medieval to modern Iberia

The Anatomical Record, EarlyView.
Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

Effect of Heat Treatment on Hydrogen Embrittlement of Electrodeposited Copper

Materials and Corrosion, EarlyView.
This work explores how entrapped hydrogen can cause embrittlement of copper, although this embrittlement is only evidenced during slow strain testing. We demonstrate that significant amounts of hydrogen are trapped in nano‐cavities and investigate the impact of heat treatment in changing the hydrogen distribution and the resulting embrittlement ...

An integrated forest‐to‐market approach to promote lesser‐known timber species (LKTS) in a domestic timber market in the Congo Basin

PLANTS, PEOPLE, PLANET, EarlyView.
In the Congo Basin, domestic timber markets account for ~40% of timber consumption, yet demand is concentrated on a few high‐value species also sought after on international markets, raising concerns about their long‐term availability. We combine market, wood, and forest data to assess the potential of lesser‐known timber species (LKTS) to support a ...
