Gas Quenching with Controllable Heat Extraction

Materials Science Forum, 2007
High pressure gas quenching became a modern way of quenching finally machined engineering components,having many advantages compared to quenching in liquid quenchants.The main shortcoming of this technology is the problem of achieving adequate hardness in the core of bigger workpieces,because of inadequate quenching intensity.Due to the possibility to ...

Extraction, Territory, and Inequalities: Gas in the Bolivian Chaco

Canadian Journal of Development Studies / Revue canadienne d'études du développement, 2010
Conflicts over extractive industry have emerged as one of the most visible and potentially explosive terrains for struggles over distribution, territory, and inequality in the Andes. We explore these relationships in Bolivia, focusing on gas extraction in the Chaco region of the southeastern department of Tarija.

Gas flow to a vertical gas extraction well in deformable MSW landfills

Journal of Hazardous Materials, 2009
Active gas control systems are commonly used in municipal solid waste (MSW) landfills and the design of such systems requires thorough understanding of the gas flow pattern. A model is developed to predict the two-dimensional radial transient gas flow to a vertical gas extraction well in deformable MSW landfills.

Gas Chromatography–Mass Spectrometry of Biofluids and Extracts

2015
Gas chromatography-mass spectrometry (GC-MS) has been widely used in metabonomics analyses of biofluid samples. Biofluids provide a wealth of information about the metabolism of the whole body and from multiple regions of the body that can be used to study general health status and organ function.

From Gas to Gas: Fundamentals of Static Headspace Extraction-Gas Chromatography

LCGC International
Headspace sampling is one of the staple sample introduction techniques for gas chromatography (GC) because it involves the injection of samples already in the vapor phase into the instrument. In this installment, we discuss the fundamentals of headspace extraction, including static versus dynamic extraction, establishing equilibrium in the vial ...
