Abstract:The striped snakehead or murrel is a highly prized foodfish in Asia. Several thousand metric tons of frozen snakeheads are imported annually to supply the existing demand for this fish by the domestic Asian seafood market. The striped snakehead was introduced to the Island of Oahu, Hawaii, in the… more
Abstract:For over a hundred years, the agricultural base in Hawaii has been sugar cane. In recent years,all plantations on the major islands of Oahu and Hawaii have closed, and many are jobless. Onealternative to work opportunities is specialty crop production, but changes in global trade haveeroded… more
Abstract:Proposed research will develop system concepts and designs for the near term prediction of inversion/crater fog or misting rain events at the Maui Space Surveillance Site (MSSS) on Haleakala, Maui, Hawaii. The time required for closure of the new 3,6m AEOS telescope dome and the high threat of… more
Abstract:The proposed research will develop the specifications and design of a ceilometer capable of scanning in three dimensions to detect clouds within a range of 75,000 feet (about 15 miles). The final design will be based upon the Vaisala CT-75k ceilometer which has a nominal range of 75,000 feet. As a… more
Abstract:The objective of the proposed project is to design, develop, and construct equipment to centrifugally filter highly corrosive process solutions using a novel technology. Central to this new technology is a replaceable, reusable, inert polymer drum which is periodically removed as it fills with… more
Abstract:This Phase I will test the application of high heat conducting carbon fibers to increase the efficiency of air/liquid heat exchangers. TRA's unique technology to apply molten copper to carbon fibers will allow the reliable construction of copper/graphite heat exchanger structures. Since TRA's… more
Abstract:THE SUCCESSFUL DEVELOPMENT OF RELIABLE, LARGE-SCALE, HATCHERY TECHNIQUES FOR THE HAWAIIAN BLACK-LIP PEARL OYSTER NOW OPENS UP THE POTENTIAL FOR BLACK PEARL FARMING IN NEW AREAS ACROSS THE PACIFIC. EFFICIENT, COST-EFFECTIVE, GROW-OUT TECHNIQUES NEED TO BE DEVISED FOR THE HIGH-ENERGY MARINE CONDITIONS… more
Abstract:Dengue virus causes dengue fever, a debilitating illness marked by high fever, headache, muscleand joint pain, and rash. The more severe forms of the illness, dengue hemorrhagic fever and dengueshock syndrome, are life threatening and are a principal cause of hospitalization among children… more
Abstract:The department of Defense is currently engaged in extensive biosensor research and development efforts. A major goal of these efforts id the development of automated field-usable systems for the detection of a variety of analytes including toxins, infectious organisms, and chemical agents in either… more
Abstract:The neurotoxins of Clostridium botulinum are the most lethal proteins known. The bacterium is ubiquitous, and thus rapid, reliable, sensitive, and cost-effective assays are needed to detect the toxin. Current immunoassays provide a rapid means to detect the neurotoxin. Their sensitivity, however,… more
Abstract:Campylobacter jefjuni and Campylobacter coli are significant pathogens of humans. In the United States, the estimated annual incidence of the disease 1-2 million cases costing almost one billion dollars in health care costs and lost productivity. Currently, effective vaccines for do not exist;… more
Abstract:Shrimp farming is the world's most valuable aquaculture sector with 1994 production of 733,000 MT and crop value of $4 billion. This huge industry depends on wild animals with its seedstock either gathered directly from the sea or produced in hatcheries from wild-caught broodstock. Recently the… more
Abstract:The primary objective of this project is to develop, characterize and demonstrate a robust, low-cost, manufacturable interface for optical fibers which are embedded in composite structural materials. The approach is to embed an optical fiber with attached ferrules in the composite. The outer end… more
Abstract:Research proposed herein will provide important insight into design and development of an array data collection system that will lead to better understanding into phenomena of internal wave interactions with steep slopes and resulting affects on convergence zone formation as well as municipal… more
Abstract:Space-based systems must dissipate tens to hundreds of watts for communications, housekeeping, etc. TRA proposes a novel thermal strap which would allow efficient energy conduction from heat sources to the structure of the spacecraft or to heat dissipation units. The thermal strap would utilize high… 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.
