BLOOD GAS AND CAROTID PRESSURE
Survey of Anesthesiology, 1976 The internal carotid back pressure and arterial blood gas measurements have been employed in 269 patients undergoing 332 carotid endarterectomies in an effort to identify individuals at high risk of stroke during surgery. Patients having an internal carotid back pressure less than 25 Torr were operated using an inlying shunt.

Numerical Modeling of Multiphase, Turbulent Galactic Disks with Star Formation Feedback
, 2012 Star formation is self-regulated by its feedback that drives turbulence and heats the gas. In equilibrium, the star formation rate (SFR) should be directly related to the total (thermal plus turbulent) midplane pressure and hence the total weight of the ...

Properties of the circumgalactic medium in cosmic ray-dominated galaxy haloes [PDF]
, 2020 We investigate the impact of cosmic rays (CRs) on the circumgalactic medium (CGM) in FIRE-2 simulations, for ultra-faint dwarf through Milky Way (MW)-mass haloes hosting star-forming (SF) galaxies.

Thermodynamics of an Accretion Disk Annulus with Comparable Radiation and Gas Pressure
, 2007 We explore the thermodynamic and global structural properties of a local patch of an accretion disk whose parameters were chosen so that radiation pressure and gas pressure would be comparable in magnitude.
