MICROSTRUCTURES, MECHANICAL PROPERTIES, AND GREASE-LUBRICATED SLIDING WEAR BEHAVIOR OF CU-15NI-8SN-0.8NB ALLOY WITH HIGH STRENGTH AND TOUGHNESS

Microstructures, mechanical properties, and grease-lubricated sliding wear behavior of Cu-15Ni-8Sn-0.8Nb alloy with high strength and toughness

Abstract Alloys used as bearings in aircraft landing gear are required to reduce friction and wear as well as improve the load-carrying capability due to the increased aircraft weights.Cu-15Ni-8Sn-0.8Nb alloy is well known for possessing good mechanical and wear properties that satisfy such requirements.In this Hooded flannel study, the microstruct

Redox signaling via oxidative inactivation of PTEN modulates pressure-dependent myogenic tone in rat middle cerebral arteries.

The present study examined the level of generation of reactive oxygen species (ROS) and roles of inactivation of the phosphatase PTEN and the PI3K/Akt signaling pathway in response to an increase in intramural pressure-induced myogenic cerebral arterial constriction.Step increases in intraluminal pressure of cannulated cerebral arteries induced myo
