Aerodynamic investigations of ventilated brake discs [PDF]
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2005 The heat dissipation and performance of a ventilated brake disc strongly depends on the aerodynamic characteristics of the flow through the rotor passages. The aim of this investigation was to provide an improved understanding of ventilated brake rotor flow phenomena, with a view to improving heat dissipation, as well as providing a measurement data ...

FEBS Open Bio, EarlyView.Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

INSPECTING A BUMP TEST IN THE MAINTENANCE OF A 1200-CC DAIHATSU SIGRA DISC BRAKE
Jurnal Ilmiah SINERGI, 2019 A motorized vehicle needs a system that can not only reduce the speed and stop the vehicle but can also serve as a safety tool and ensure a safe distribution which is called a braking system. It is important to conduct maintenance of a disc brake that is

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.
