Two columns on articles by Ian Urbina about the development of shale gas drew strong responses.
A star forms when a cloud of interstellar gas draws itself together through gravity, growing denser and hotter until fusion ignites.
Disks of hot gas drawn onto a central star or black hole are the best energy-producing machines in the Universe.
Hydrogen gas, drawn through a permeable membrane coated with a thin layer of platinum, combines with oxygen from the air to create electricity to run a motor and water vapour that puffs out of exhaust pipes.
A medium of some sort, usually a gas, draws heat from a hot body or bath to do mechanical work, such as moving a piston.
Simply put, Americans want big, heavy motors, and they associate displacement (the volume of air and gas drawn in by an engine) with power.
The project, underwritten Petronaus and led by its Canadian subsidiary Pacific Northwest LNG, is looking to connect natural gas drawn from fracking wells in the highlands of Alberta and northeastern British Columbia to a massive liquid natural gas terminal that aim to build on an island off the coast from Prince Rupert, B.C. From there, the gas would be loaded onto supertankers, destined for Asia.
Lavage was repeated until the arterial blood gas, drawn 5 min later, showed PaO2/FIO2 ratio (P/F) < 100.
His pledge that day to use every means to combat heat-trapping gases drew applause from clean-air groups.
The new rule, limiting emissions of carbon dioxide and other greenhouse gases, drew legal and technical objections from the electric power industry.
