Chewable softgels are a patient‐preferred alternative to conventional oral forms, offering pleasant taste, fast onset, and suitability for children or patients with swallowing difficulties. However, they present relevant challenges in their formulation: the shell must balance chewability, machinability, and stability, while the fill must mask the ...

This study experimentally evaluates the performance of eco‐friendly vegetable‐based cutting fluids—coconut, sunflower, and palm oils—during turning of AISI 304 stainless steel under minimum quantity lubrication. Palm oil exhibited superior lubrication and cooling characteristics, yielding the lowest cutting force, temperature, and surface roughness ...

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears
ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...

ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Recyclability of Polystyrene Bead Foams: Degradation Behavior over 10 Extrusion Cycles
This study investigates the multi‐cycle recycling of expanded polystyrene bead foam blended with virgin material. Material degradation is monitored by MFI, GPC, and mechanical testing. The results demonstrate that long‐term recyclability is feasible without progressive property loss, and that secondary high‐shear steps such as extrusion and pelletizing
