Abstract:Current animal studies are limited by the requirement for batteries in animal telemetry devices. Problems include limited operational life and duty cycle of the devices, as well as limiting the species studied due to battery weight. The purpose of this study is to demonstrate the feasibility of… more
Abstract:Commercialization potential for unit-dose vials with shaft applicator and applicator tip is extremely promising. There is emerging market demand for this product, but no such products are presently available. The project investigates the optimum configuration(s), material(s) and attachment method(s)… more
Abstract:Application of chemicals with irrigation water is a widely adopted practice with center pivot irrigation systems, however, the standard practice of chemical injection at a constant rate results in systematic chemical application errors ranging from 7 to 22% for center pivots equipped with a corner… more
Abstract:NON-TECHNICAL SUMMARY: Economic impacts due to coldwater disease (CWD) have dramatically increased in recent years at public and private aquaculture facilities and CWD is the number one disese problem in the commercial rainbow trout industry in Idaho. In the United States, antibiotics available for… more

Abstract:NON-TECHNICAL SUMMARY: The fire hazard in many forests is increased by small diameter trees which are costly to remove. The technology described in this proposal will allow an operator to monitor and control a number of small, unmanned vehicles. These vehicles will reduce the cost of removing small… more
Abstract:The threat of biological attack can be mitigated by deployment of acost-effective bioaerosol sensor network. For U.S. forces inparticular, the high false alarm rate of the Biological AerosolWarning System is very costly. This project will demonstrate thefeasibility of a novel bioaerosol sampling… more
Abstract:Feasibility testing of a novel high-throughput, tilt-compensated interferometer design is proposed. The Phase I effort will demonstrate a prototype and two manufacturing techniques for lowering costs. The novel optical design offers excellent interferometric stability, inexpensive manufacture and… more
Abstract:The work proposed here will demonstrate the feasibility of a high-sensitivity,scanning-etalon infrared spectrometer to detect silent chemical threats, inresponse to Subtopic 1 of the solicitation. There is a critical needthroughout the DoD, the U.S. government, and the commercial sector for… more
Abstract:NON-TECHNICAL SUMMARY: Many rural Native American communities suffer high rates of chronic disease related to contemporary diets, including the Kalispel Tribe. Native bulbs originally used as staples in these communities, are scarce due to the loss of indigenous ways of life and traditional uses of… more
Abstract:This Small Business Innovation Research (SBIR) Phase II Project proposes to develop an innovative solution to the the problem of chlorinated solvent contamination in variably saturated, low permeability soils. Prior Phase I work has demonstrated that: 1) chitin is an effective electron donor for… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
