Engineering Reports, Volume 8, Issue 5, May 2026.A numerical investigation using 3D RANS simulations demonstrates significant effects of protuberance geometry—cubic, cylindrical, spherical, and conical—on shock‐induced thrust vectoring in supersonic nozzles. Cubic protuberances provide the maximum jet deflection (˜2°) with negligible thrust reduction.

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading
Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Plant‐based proteins, such as soybean meal (SBM), have shown promising results in cultured species but also present challenges due to their nutrient composition and inherent antinutritional factors. This study investigated how the replacement of solvent‐extracted SBM with low oligosaccharide soybean meal (LSBM) or enzyme‐treated soybean meal ...
