PENGARUH JARAK MISALIGNMENT DRIVE SHAFT COOLING TOWER TERHADAP TEGANGAN NORMAL DAN TEGANGAN GESER
Rekayasa Mesin, 2022 The purpose of this study was to determine the effect of misalignment distance of Cooling Tower drive shaft on normal stress and shear stress. Tensions that occur on the shaft continuously for a long time cause the shaft to experience fatigue.

A Shaft Generator System without Output Voltage Distortion
IEEJ Transactions on Industry Applications, 1999 A shaft generator system, which consists of a shaft generator, a rectifier, an externally commutated thyristor inverter, an ac reactor, and a synchronous condenser, is being increasingly used mainly in large ships. Conventional type of the shaft generator system has a fundamental drawback of involving a large amount of harmonics in the output voltage ...

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells
Molecular Oncology, EarlyView.We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox

TMC4 localizes to multiple taste cell types in the mouse taste papillae
FEBS Open Bio, EarlyView.Transmembrane channel‐like 4 (TMC4), a voltage‐dependent chloride channel, plays a critical role in amiloride‐insensitive salty taste transduction. TMC4 is broadly expressed in all mature taste cell types, suggesting a possible involvement of multiple cell types in this pathway.
