N/A

High-volume, low-VOC-concentration air streams are produced by a broad range ofindustries. The most widely used conventional treatment technology is carbonadsorption. However, carbon adsorption produces dilute aqueous waste streams asa secondary waste, is difficult to adapt to particulate-containing streams, andis too expensive to be applied by some industries. Wet scrubbing the air is alow-cos ...

N/A

In situ bioremediation would significantly reduce the costs and risks associatedwith the cleanup of chlorinated aliphatic hydrocarbon (CAH) solvent contaminationin the vadose zone and in groundwater. CAH remediation requires controlledaccess to the subsurface for delivery and mixing of a variety of chemical andbiological agents. Safe, cost-effective, and controlled access for CAHbioremediation i ...

N/A

Combustion in boiler and fluids heaters consumes approximately 5 TCF of gas peryear and generates approximately 350,000 tons of NOx. To meet ambient airquality standards, particularly those for ozone, low-cost ultra-low NOx burnersare needed for these applica-tions. This will reduce the costs and increase thecompetitiveness of industry that might otherwise be forced to use the expensiveSelective ...

N/A

The specific problem addressed by the proposed research is the development of a scanner for storage phosphor plates with significantly better positional and intensity accuracy than the current state of the art. The new scanner will be based on the use of a "scanning head" scanning approach which is more simple, accurate, and stable than the approaches previously used. This results in stable and ...

A solution to the need for OD 3 to OD 10 neutral density filters in the infrared (2 to 25 um) with flat wavelength dependence is suggested using submicron thickness polymer films as substrates for multi-layer or co-deposited metallic alloy coatings. Initial studies used Lexan and although they showed feasibility, a stronger and more temperature resistant ultrathin substrate such as polyimide film ...

The purpose of the Thomas Drop Net Concept is to introduce a new method of catching pure schools of surface feding fish with the ability to select only those schools of targeted species which are of desirable size. The method involves a helicopter deployed drop net which is lowered around a selected school of targeted species, pursed, and left floating. When the seiner arrives, they place a tr ...
