Twelve years after TWA Flight 800 exploded off Long Island on July 17, 1996, killing all 230 people aboard the Boeing 747, the Federal Aviation Administration FAA has issued a final rule aimed at reducing the threat of fuel tank explosions aboard commercial passenger transports. The...
OAKLAND -- A neighborhood in West Oakland can breathe easier after tests for dangerous levels of hazardous compounds in the air came back negative, according to federal environmental officials. On Friday, the U.S. Environmental Protection Agency tested about a half-dozen homes, a business and a day care center...
Data from NASA'S Cassini spacecraft raise new questions about the origin of Saturn's tiny moon Enceladus and the heat driving its plume of ice and water vapor. Cassini lived to tell the tale of its March 12 brush with the enormous plume of ice, water vapor, and gas spewing...

INTRODUCTION In small-capacity refrigeration systems, cooling capacity is controlled by a succession of ON/OFF compressor cycles whose frequency depends on thermal load and cold ambient temperature requirements. During each one of such cycles, immediately after the compressor turns off, a process of vapor refrigerant absorption in the oil inside...

Some things are so obvious we miss them. The second law of thermodynamics is like that. Of course, the crazy way we speak about the second law does not help. "In an isolated system, a process can occur only if it increases the total entropy of the system." Huh? It...
The migration of vapors from contaminated groundwater and soil into aboveground buildings can adversely affect indoor air quality by creating an exposure pathway that may not have been addressed previously. Vapor intrusion VI is an emerging concern that may impact thousands of hazardous, brownfields and commercial/industrial waste sites...
Remediation System Engineered by U.S. Navy Saves Time and Money While Cleaning Up Toxic Waste Dump While Americans and their government have been dumping toxic wastes in soil and bodies of water for decades, it's only been in the past 40 years that the cost to human health,...
LAYTON -- Hill Air Force Base is getting ready to redraw the map of a two-lobed plume of shallow groundwater contamination in Layton. And though it may come as a surprise to some residents to find the plume is bigger than the current map shows, Hill officials want...
For batch processes, use a surrogate feed stream to simulate the inlet conditions necessary for stack testing to demonstrate compliance. The Miscellaneous Organic NESHAP National Emission Standards for Hazardous Air Pollutants, or MON rule (1), requires companies to demonstrate the control efficiency of air-pollution control devices used to...
Two federal agencies disagree over the need to eliminate vapors from all airliner fuel tanks; it may take a new tragedy to prove the necessity. By David Evans "Look at that crazy fuel flow indicator there on No. 4. See that?" exclaimed Capt. Ralph Kevorkian. Sitting...
Recent testing of a specialized steam vapor system at the University of Washington UW, Seattle's Odegard Undergraduate Library proves this method yields excellent results, requires few if any chemicals and very little facility downtime. Technical specialists from Advanced Vapor Technologies, Edmonds WA, trained...
Nanostructured materials have shown great potential in improving the sensitivity and reliability of chemical and biological sensors. The ability to control the geometric shape (size, separation, orientation, alignment, etc.) of nanostructures and to integrate nanostructures from different materials becomes one of the great challenges for sensor fabrication. Glancing angle deposition...
