This fragmental material was interrupted by explosions of steam, water, ash, rock, and volcanic bombs called phreatic eruptions.
We've also seen the renaissance of the PC as a gaming platform, thanks to the explosion of the Steam digital distribution platform.
The site's uniqueness worked against it; the geologists had seen plenty of features caused by volcanoes, but none caused by a meteorite, so they attributed the crater to volcanic action or an explosion of underground steam.
"So many stories actually overlap," Mr. Scarborough said, noting the national significance of events like the explosion of a steam pipe in Midtown in July or the importance to New Yorkers of a recent videotape of Osama bin Laden.
In recent years, he has responded to some of the city's most serious emergencies, including the deadly Staten Island ferry crash in 2003 and the explosion of a steam pipe in Midtown in 2007.
Similar large explosions occurred on 10 May and 17 July 1999, interspersed with numerous smaller explosions of white steam or darker ash-bearing steam.

Such representations not only contribute to utilization of energy but considerably facilitate optimization, simulation, design and control of steam explosion process, consequently improving the large-scale deployment of steam explosion technology.
In this study we have investigated the effect of steam explosion parameters on wheat straw digestibility using a newly designed steam explosion unit and a process without acid impregnation.
