Barometric pressure changes affect air density, leading to change in the mass of the gas in the gob. When the barometric pressure decreases, the volume of gas in the gob expands, while the volume of gas contracts when the barometric pressure increases, causing the gob to breathe out and in. Although the concept of gob “breathing” is simple, its effect on spontaneous heating of coal in the gob a...

[1] We investigate the thermodynamic structure of interplanetary coronal mass ejections (ICMEs) using combined surveys of the ejecta between 0.3 and 20 AU. ICMEs are shown to have a moderate expansion in the solar wind compared with theoretical predictions. The expansion seems to be governed by a polytrope with g 1.3 in this distance range. We find that Coulomb collisions are important contribu...

We have previously reported that administration of atropine (A) to unrestrained, sedentary, heat-stressed rats resulted in a dose-dependent increase in heating rate (rate of rise of core temperature, degree C/min). Additionally, we have demonstrated that the decrements in treadmill endurance and increments in heating rate of physostigmine (PH)-treated running rats can both be restored to contro...

We measure feedback (heating rates) in damped Lyα systems (DLAs) from the cooling rate of the neutral gas. Since cooling occurs through [C II] 158 μm emission, we infer cooling from C II 1335.7 absorption lines detected with HIRES on the Keck I telescope. The inferred heating rates are 30 times lower than for the Galaxy ISM. At z ≈ 2.8 the implied star formation rate per unit area is logψ∗=−2.4...
