In the event of a terrorist attack, the ability to measure the extent and location of the attack and rapidly notify first responders will be critical to saving lives. If the widespread use of cell phones could be harnessed with an ability to detect chemical threats and immediately notify authorities of the scope and location of the attack, public safety would be significantly enhanced. Synkera pro ...

Biodiesel is a fuel that is made by processing vegetable oil or animal fats into a liquid fuel that can be combusted in a standard, unmodified diesel engine. The use of biodiesel reduces CO2 emissions by over 80% compared to petroleum and it reduces our dependence on foreign oil while promoting economic opportunities in rural America. When biodiesel is made from low-cost waste oils or fats the e ...

PHENOLIC COMPOUNDS ARE THE PRIMARY WASTEWATER TREATMENT CHALLENGE FOUND IN THE AQUEOUS EFFUENTS FROM PETROLEUM REFINERIES, COAL CONVERSION PROCESSES, PETROCHEMICAL PRODUCTION, AND THE MANUFACTURE OF PHENOLS AND RELATED CHEMICALS. EMULSION LIQUID MEMBRANE (ELM) SEPARATIONS ARE ADEVELOPING TECHNOLOGY WITH HIGH POTENTIAL FOR COST-EFFECTIVEREMOVAL AND RECOVERY OF PHENOLIC COMPOUNDS. UNLIKE CURRENT TRE ...

METHANOL FUELED DIESELS ARE AN ATTRACTIVE MEANS OF MEETING STRINGENT 1994 DIESEL PARTICULATE STANDARDS, AND ARE A TOPICOF INTENSE INDUSTRIAL INTEREST. UNFORTUNATELY, BECAUSE OF METHANOL'S AUTOIGNITION TEMPERATURE IS HIGH AND ITS IGNITIONDELAY IS LONG, SOME MEANS OF IMPROVING ITS IGNITION IS REQUIRED IF IT IS TO BE USED IN A DIESEL ENGINE. THE BEST CURRENT METHOD, USE OF HIGH EXHAUST GAS RECIRCULAT ...

THE OBJECTIVE OF THIS STUDY IS TO DEMONSTRATE THAT THE PERFORMANCE OF INCINERATORS CAN BE IMPROVED BY RETROFITTING THEM WITH A PULSE COMBUSTER WHICH WILL EXCITE ACOUSTIC PULSATIONS WITHIN THE SYSTEM. BASED UPON EVIDENCE PROVIDED BY RELATED STUDIES, THESE PULSATIONS ARE EXPECTED TO INCREASE THE MIXING RATE BETWEEN THE FUEL AND OXIDIZER, ANDTHE BURN RATE OF WASTE; IMPROVEMENTS WHICH ARE EXPECTED TO ...

SIGNIFICANT CONSERVATISM IN MODERN SEISMIC PRA DERIVES FROM SIMPLIFICATIONS IN GROUND-MOTION CHARACTERIZATION AT THE INTERFACE OF SEISMIC HAZARD AND FRAGILITY METHODOLOGIES. THIS CONSERVATISM ARISES BECAUSE A SINGLE COMPOSITE-MAGNITUDE, BROAD-BAND, GROUND-MOTION SPECTRUM IS USED TO DERIVE FRAGILITY FUNCTIONS, WHEREAS THE MAJORITY OF MOTIONS CONTRIBUTING TO SITE HAZARD HAVE (LESS-DAMAGING) NARROW-B ...

Toxic Industrial Chemicals (TICs) are chemical substances that produce toxic effects if given in sufficient quantities and/or exposed for long durations. TICs are a great concern for the U.S. Department of Homeland Security (DHS) since it would be easier for terrorists to obtain and use than CAs. There are many commercially available handheld and personal gas monitors to monitor TICs. However, the ...

In many parts of the country groundwater withdrawals exceed recharge rates and this has caused groundwater-level declines, reductions to the volume of groundwater in storage, lower streamflow and lake levels. Development of brackish groundwater and seawater as an alternative water sources can_x000D_ help address concerns about the future availability of water. Thus, there is a need for a technolog ...

Marietta X-Ray, Inc (MXRI) and its subcontractor Rapiscan Laboratories, Inc. propose to develop a mobile non-intrusive prototype that can demonstrate the capability of inspecting a complete general-aviation aircraft for concealed contraband. Our solution utilizes an existing vehicle and manipulator coupled with an x-ray inspection system. The x-ray system is based on backscatter technology, which ...
