Formation Principle and Characteristics of Self-Supercharging Pulsed Water Jet
Chinese Journal of Mechanical Engineering, 2022 High-pressure pulsed water jet technology has considerable development potential in the field of rock fragmentation. To overcome the shortcomings of existing pulsed jets, a self-supercharging pulsed water jet (SSPWJ) generation method is proposed, which ...

Effect of pulse pressure on borehole stability during shear swirling flow vibration cementing. [PDF]
PLoS ONE, 2017 The shear swirling flow vibration cementing (SSFVC) technique rotates the downhole eccentric cascade by circulating cementing fluid. It makes the casing eccentrically revolve at high speed around the borehole axis.

Pressure Pulse in Small Arteries [PDF]
Circulation Research, 1962 Pressure pulse contours have been obtained in the small mesenteric and intestinal arteries of the dog. The principal change in the pressure pulse during transmission from large to small arteries appeared to be the gradual and progressive development of damping. The pressure drop from the aorta to arteries of 200 µ internal diameter averaged 17 per cent

Pulse Pressure and Cardiovascular Death
Journal of the American College of Cardiology, 2016 We read with great interest the study of Selvaraj et al. [(1)][1], which provides robust evidence on the predictive role of pulse pressure (PP) for cardiovascular (CV) outcomes. Surprisingly, however, when the predictive ability of a 10 mm Hg increase in PP was assessed, a “protective ...

Pulse pressure and perioperative stroke [PDF]
Current Opinion in Anaesthesiology, 2019 Central pulse pressure (PP), a marker of vascular stiffness, is a novel indicator of risk for perioperative morbidity including ischemic stroke. Appreciation for the mechanism by which vascular stiffness leads to organ dysfunction along with understanding its clinical detection may lead to improved patient management.Vascular stiffness is associated ...

Composite pressure cell for pulsed magnets
Review of Scientific Instruments, 2021 Extreme pressures and high magnetic fields can affect materials in profound and fascinating ways. However, large pressures and fields are often mutually incompatible; the rapidly changing fields provided by pulsed magnets induce eddy currents in the metallic components used in conventional pressure cells, causing serious heating, forces, and vibration.
