Residual gas expulsion from young globular clusters

The results of N -body simulations of the effects of the expulsion of residual gas (that gas not used in star formation) from very young globular clusters is presented. Globular clusters of a variety of initial masses, Galactocentric radii, concentration and initial mass function slope with star formation efficiencies of < ∼ 50% were simulated. The residual gas was expelled by the action of mas...

Experimental and Numerical Pore Scale Study of Residual Gas Saturation in Water/Gas Imbibition Phenomena

Residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. Visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. In this study experimental tests in a glass micromod...

Part II. A Portable Miniaturized Metabolic Gas Analysis System

Introduction Previously we proposed construction of a miniaturized metabolic monitor that could be taken aboard the space station to monitor the physiological response of the body in a microgravity environment. The prototype consisted of an on airway non-dispersive infrared (NDIR) CO2 sensor and a luminescencequenching O2 sensor to measure gas concentrations, and differential pressure ports to ...

Gas-liquid chromatography in the analysis of mercury (II) compounds.

Gas-liquid chromatography (GLC) in recent years has found application in the analysis of various metals, either singly (1) or in tandem function with mass spectrometry (2), and presently is gaining wide acceptance in the analysis of organomercury(II) compounds. Since increasing use of GLC in mercury analysis may be anticipated for both research and monitoring purposes, it is of value at this po...
