A multiscale seasonal examination of the risk of harm to seabirds from vessels based on co‐occurrence in Alaskan waters

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Alaska's seascape supports globally significant seabird populations, including vulnerable and threatened species, and hosts economically important commercial fisheries and marine transportation corridors. Seasonal patterns of seabird movements and vessel traffic create a complex landscape of risk, defined as high levels of co‐occurrence ...

CFD Analysis of Hybrid Ionanofluid Flow in a Parabolic Trough Solar Collector With Helically Finned Absorber Pipe

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
The increasing global demand for sustainable energy emphasizes the need for improved solar thermal technologies. Parabolic trough solar collectors (PTSCs) in concentrating solar power systems face limited thermal efficiency due to suboptimal heat transfer fluids (HTFs) and outdated absorber designs.
