Prediction and Application of Pore Pressure in Guangming Structure Formation of Hetao Basin
To ensure drilling safety and optimize reservoir evaluation in ultra-deep and high-pressure formations of the Guangming structure in the Hetao basin, solve accidents such as overflow and collapse caused by inaccurate pore pressure prediction, and support

Numerical study of the collapse of a bubble subjected to a lithotripter pulse [PDF]
The collapse of a bubble subjected to a lithotripter pulse is studied numerically. The goal is to record the pressure exerted along the stone, as a measure of potential stone damage. It is found that the pressure due to buble collapse is much larger than

Objective We aimed to test the efficacy of personalized treatment of older veterans with chronic low back pain (CLBP) delivered by Aging Back Clinics (ABCs) as compared with usual care (UC). Methods Two hundred ninety‐nine veterans aged 65 to 89 with CLBP from three Veterans Affairs (VA) medical centers underwent baseline testing, randomization to ABC ...

Research on Wellbore Collapse of Stratification Formation
The development micro-fractures, joints and bedding in the middle and deep strata of the Bohai Oilfield makes the collapse pressure predicted using conventional integrate formation not consistent with actual situation.

Rebounce and Black hole formation in a Gravitational Collapse Model with Vanishing Radial Pressure
We examine spherical gravitational collapse of a matter model with vanishing radial pressure and non-zero tangential pressure. It is seen analytically that the collapsing cloud either forms a black hole or disperses depending on values of the initial ...

Stability and collapse of rapidly rotating, supramassive neutron stars: 3D simulations in general relativity [PDF]
We perform 3D numerical simulations in full general relativity to study the stability of rapidly rotating, supramassive neutron stars at the mass-shedding limit to dynamical collapse. We adopt an adiabatic equation of state with $\Gamma = 2$ and focus on

Objectives Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies. To help patients and providers in the decision‐making process, we developed

Radiation Pressure in Massive Star Formation [PDF]
Stars with masses of >~ 20 solar masses have short Kelvin times that enable them to reach the main sequence while still accreting from their natal clouds.

In this paper, we used a Venturi tube for generating hydrodynamiccavitation, and in order to obtain the optimum conditions for this to be used in chemical processes, the relationship between the aggressive intensity of the cavitation and the downstream ...
