Demonstration of Ozone Impacts on Crop Species in the San Joaquin Valley: Open Top Chambers at Kearney
Agricultural Center
Grantz, D. A.; Dec. 2003; 98 pp.; In English
Report No.(s): PB2004-106392; No Copyright; Avail: CASI; A05, Hardcopy
The San Joaquin Valley exceeds state and federal air quality standards for ozone. Agricultural interests are politically and
socially important, yet despite documented crop damage and yield loss due to ozone, this segment of the population has been
less supportive of air quality regulatory activity than others. A research and demonstration project was designed to increase
recognition of ozone symptoms in crops of the ozone problem in general. The object was to increase participation in air quality
improvement initiatives. Plants were exposed in Open Top Chambers and a web site was developed for non-specialist and
specialist adults, and for children. Visits, site tours and other activities were hosted at the University of California Kearney
Agricultural Center in Parlier. Research activity provided demonstration materials. Outreach was limited during the period of
the project as economic pressure cancelled many tours and air quality regulatory issues contentious. Useful outreach materials
and a continuing physical and web-based presence were established.

Improving the University of Idaho Clean Snowmobile

Report No.(s): PB2004-105903; No Copyright; Avail: CASI; A03, Hardcopy
The University of Idaho’s entry into the 2001 SAF Clean Snowmobile Challenge provided proof-of-concept for a clean
and quiet snowmobile using a four-stroke engine, exhaust after-treatment and electronic fuel injection. This combination
provided excellent emissions and fuel consumption performance while maintaining acceptable power. In 2002, the UI
improved on this design by fine-tuning the engine, using higher efficiency components to improve power transmission, and
adding sound damping to reduce noise. For 2003, the University of Idaho continued to improve on this design with a larger
displacement engine, a tuned exhaust, and a new strategy on noise emissions. Results included achieving First Place overall
in the competition, and five other awards. The team also began developing a direct injection two-stroke engine for competition
in future years.

Report No.(s): DE2003-818090; No Copyright; Avail: National Technical Information Service (NTIS)
This report discusses test campaign GCT4 of the Kellogg Brown & Root, Inc. (KBR) transport reactor train with a
Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development
Facility (PSDF) located in Wilsonville, Alabama. The transport reactor is an advanced circulating fluidized-bed reactor
designed to operate as either a combustor or a gasifier using one of two possible particulate control devices (PCDs). The
transport reactor was operated as a pressurized gasifier during GCT4.
