River Mouth Hydrodynamics: The Role of the Outlet Geometry and Transient Tidal and River Discharge Conditions on the Jet Structure

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 1, January 2025.
Abstract The hydrodynamics of river mouths are the result of a complex interaction between river flow, tidal conditions, and outlet geometry. This complex interaction of factors shapes the jet that flows onto the continental shelf and influences the dynamics of these areas.

Gender‐Based Differences in the Biomechanical Behavior of the Thorax During CPR Maneuvers

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, Volume 40, Issue 12, December 2024.
Cardiopulmonary resuscitation (CPR) is a common emergency procedure for cardiac arrest. This study presents numerical experiments simulating this maneuver in both genders to determine the optimal location and force for chest compressions. By analyzing deformation and stress, this investigation demonstrates that the ideal compression point is lower on ...

Spark plasma sintering of hard wear‐resistant graphene nanoplatelet–reinforced TiB2 + SiC composites from TiC–B4C–SiC

open access: yesJournal of the American Ceramic Society, Volume 107, Issue 12, Page 8521-8529, December 2024.
Abstract Graphene nanoplatelet (GNP)–reinforced TiB2 + SiC composites were fabricated by reactive spark plasma sintering (SPS) from a TiC–B4C–SiC powder mixture with equal‐volume percentages, optimizing their SPS temperature and evaluating their unlubricated sliding wear against diamond. First, it is shown that during the heating ramp of the SPS cycle,
