Therapeutic control of blood pressure (BP) in an "all‐comer" patient population is associated with a reduction in cardiovascular mortality. 1 Recent evidence and contemporary guidelines suggest that the benefit of strict therapeutic reduction in BP (systolic BP [SBP] <120 mm Hg and diastolic BP [DBP] <80 mm Hg) confers additional benefit in patients with diabetes …
An alternative, bottom-up method for diamond synthesis is high-pressure, high-temperature (HPHT) equilibrium phase conversion (14–17).While HPHT processes have produced doped diamonds, the rational formation of heteroatomic defects has remained elusive ().In addition, HPHT experiments, including diamond syntheses, conventionally use noble gas pressure …

In this section, a comprehensive derivation of the artificial compressibility method for high-pressure transcritical flows developed in this study is presented. First, Section 3.1 outlines the asymptotic expansion approach utilized to decompose pressure into thermodynamic and hydrodynamic parts.
The extra gas improves HPGL's performance in most situations. Only when the GOR and reservoir pressure are high enough can lift gas reduce flow. In this condition, the well flows without artificial lift, so adding lift gas can increase friction and decrease well production. For ESPs, extra gas inhibits performance.
Artificial diamonds can be made using high-pressure, high-temperature presses. Suppose an artificial diamond of volume 1.10 10−6 m3 is formed under a pressure of 5.10 GPa. Find the change in its volume (in m3) when it is released from the press and brought to atmospheric pressure. Take the diamond's bulk modulus to be B = 194 GPa.
work, therefore, addresses this problem by extending the artificial compressibility method to high-pressure transcritical fluids. This method is based on decoupling the thermodynamic and hydrodynamic parts of the pressure field, such that the acoustic time scales can be externally modified without severely impacting the flow physics of the problem.
This study introduces a novel phosphate-based packer fluid, designed for use in high-temperature and high-pressure oil and gas wells.

For pressures above 1 million atmospheres, there are currently just two methods of generating high pressures: (1) static compression with diamond anvil cells, and (2) "dynamic" (shock wave) compression using very high speed impactors (up to around 8 km/sec) launched by two-stage light-gas guns.
Hydrostatic conditions are generally pursued in high-pressure research, maintained to prevent the intrinsic pressure gradient on the culets of diamond anvil cells (DACs) from introducing heterogeneity to the structure and physical properties of the regulated materials.
Treatment with high-pressure CO 2 pneumothorax significantly increased the cell viability (P < 0.001) and the cell invasion (P < 0.001). Significantly higher expression of adhesive- and metastasis-related molecules was also observed. Further experiments indicated that the high-pressure CO 2 pneumothorax might increase cell invasion and metastasis through the high …
