We consider the thermodynamic properties of the constant curvature black hole solution recently found by Bañados. We show that it is possible to compute the entropy and the quasilocal thermodynamics of the spacetime using the Einstein-Hilbert action of General Relativity. The constant curvature black hole has some unusual properties which have not been seen in other black hole spacetimes. The e...

[1] Ocean bottom pressure estimates from Gravity Recovery and Climate Experiment (GRACE) have been validated by comparisons with an array of in situ bottom pressure measurements. The 600 km by 600 km array comprised 46 bottom pressure sensors that were part of the Kuroshio Extension System Study (KESS). Validations in other ocean regions have been limited by available data to pointwise bottom p...

The thermodynamic Euler equation for high-energy states of large-$N$ gauge theories is derived from the dependence extensive quantities on number colors $N$. This relates energy state to temperature, entropy, degrees freedom and its chemical potential, but not volume or pressure. In context gauge/gravity duality we show that dual generalized Smarr formula black holes in presence a negative cosm...

Physiologists and clinicians commonly refer to "pressure" as a measure of the constraining effects of the pericardium; however, "pericardial pressure" is really a local measurement of epicardial radial stress. During diastole, from the bottom of the y descent to the beginning of the a wave, pericardial pressure over the right atrium (P(pRA)) is approximately equal to that over the right ventric...

The effects of small intestinal infusion of nutrients on the transpyloric flow and pyloric resistance were evaluated in anaesthetized pigs. Saline versus isocaloric solutions of dextrose, triglycerides and casein were infused into a jejunal loop during saline gastric loading. Antropyloroduodenal pressures were measured with a sleeve/side-hole manometric assembly and the transpyloric flow with a...

We investigate the thermodynamic properties of 3+1 dimensional black holes in asymptotically de Sitter spacetimes, conformally coupled to a real scalar field. use Euclidean action approach, where boundary value data is specified at finite radius `cavity' outside hole, working extended phase space cosmological constant treated as pressure. examine structure these through their free energy. For M...

The process of the Joule–Thomson adiabatic expansion within rational NED (RNED)-AdS spacetime is investigated. isenthalpic $$P{-}T$$ diagrams and inversion temperature are depicted. depends on magnetic charge RNED coupling constant black holes. When coefficient vanishes, a cooling-heating phase transition occurs. We consider cosmological as thermodynamic pressure, hole mass treated chemical ent...

The high temperatures existing within a geothermal well preclude the use of most logging instrumentation which is necessary to study the wellbore and surrounding rock matrix. Possible solutions to this problem include cooling the wellbore and the surrounding rock by circulating fluid in the wellbore and by injecting fluid directly into the rock matrix. The latter method, however, is not preferr...
