The objective of the Phase II research is to utilize the lessons learned from the Phase I risk reduction work to develop a prototype CAD-programmable environment for the development of condition-based maintenance systems for rotorcraft. This developmentenvironment features a CAD scenario modeler for constructing, via click n' drag modeling, fault-to-failure damage models which can account for the ...

Subsurface treatment for arsenic removal (STAR) is an innovative technology for treatment of arsenic in groundwater at the wellhead. The STAR technology can result in large cost savings when compared with conventional above-ground treatment methods. The goal is to create a subsurface biogeochemical barrier composed of reactive iron hydroxide minerals and iron bacteria within the aquifer surround ...

More than 70 percent of U.S. arsenic consumption¿representing approximately 37 million pounds of arsenic per year¿is used to produce chromated copper arsenate (CCA), a wood preservative. Weathered lumber in decks, docks, playground equipment, and garden construction can leach significant amounts of arsenic into soil and water, where it poses health risks to humans and animals. Effective Decemb ...

To help improve air quality, the U.S. Environmental Protection Agency is seeking innovative and cost-effective new technologies to remove volatile organic compounds (VOCs) from the emissions of stationary sources. The current technologies, carbon adsorbers and catalytic thermal oxidizers, are heavy, expensive, insufficiently regenerating, and sometimes not sufficiently effective to meet regulator ...

Concerns regarding both the presence of endocrine disruptors in food, water, or other environmental media as well as the potential risk they pose to humans and wildlife have been growing in recent years. Passage of the Food Quality Protection Act and Amendments to the Safe Drinking Water Act reflected these concerns and required the U.S. Environmental Protection Agency (EPA) to develop a screenin ...

During this Phase I research project, MO-SCI Corporation will develop a method for recycling industrial phosphate waste as a low-cost raw material for innovative iron phosphate glass fibers. Iron and zinc phosphate sludge generated by the automobile, heavy equipment, appliance, fastener, and other industries using metal phosphating processes typically is landfilled. Preliminary work on industria ...

To comply with the U.S. Environmental Protection Agency¿s (EPA) directive of 10 ppb levels for arsenic in drinking water, there is an urgent need to develop new, simple, and effective treatment systems that can be qualified as best available technologies (BAT) to remove this toxic substance from water. Towards this goal, Materials Modification, Inc. (MMI) proposes to develop a novel arsenic-remo ...

With the maximum contaminant level for arsenic in drinking water decreasing from 50 ppb to 10 ppb in 2006, a heavy financial burden will be placed on small water-treatment facilities serving less than 10,000 people. At present, adsorption on activated alumina is preferred for removing arsenic in these small facilities because this process has relatively low capital costs and low operating expense ...

The CDL Standard and associated channelization structure was established over 20 years ago and are not optimized for current networking technologies. As networking technologies are integrated into CDL and new sensors are deployed, the demand for CDL bandwidth is increasing. Specifically, the insertion of ATM into the CDL architecture has raised some issues concerning data integrity due to the hi ...

A B technologies proposes to conduct advanced research leading to development of an enhanced Personal Visualization Environment (PVE) that will provide visualization of fused, multi-sensor, multi-spectral, image and non-image data from external sources. Our progress shows that a lightweight, eyeglass from factor having capabilities of full and partial transmissivity or full immersion virtual view ...
