Abstract:DESCRIPTION (provided by applicant): Roughly 500,000 cancer patients are treated with radiotherapy each year. Acute and late sequelae of radiotherapy have a negative impact upon the quality of life of cancer survivors. These sequelae include proctitis, cys
titis, esophageal stricture, cutaneous… more
Abstract:DESCRIPTION (provided by applicant): The long-term goal of this application is to develop mannan derived from Baker's yeast as asthma therapy. The limitations of currently available immunomodulators are their toxicity at higher doses and the lack of benefi
cial effect on airway smooth muscle (ASM)… more
Abstract:This Small Business Technology Transfer (STTR) Phase II research project will advance a Mobile Robotic Welding System (MRWS) to significantly improve automated ship fabrication techniques in the United States. Providing automation to the American shipbuilding industry poses significant challenges.… more
Abstract:Piezoelectric motors operate on the principal of converting the high-frequency oscillation of high-force, precision ceramic elements into useful continuous motion. High-power oscillations are converted to rotary motion through novel transmission mechanisms to produce high-torque, precision motion. … more
Abstract:The most common method for utility energy storage in the US is pumped hydro, which has very low energy density (~ 1.1 kWh/m3) and long response times (1 to 5 min). Another method is the use of rechargeable batteries such as lead acid batteries (40 kWh/m3), which require high maintenance and have a… more
Abstract:It is becoming increasingly apparent that we, as a nation, need to quickly develop an alternative and sustainable energy supply. This is due to a host of factors, including uncontrollable fluctuation in oil prices, large oil supplies being controlled by foreign regimes, global shrinking oil… more
Abstract:Formaldehyde (H2CO) has been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC) since 2004. Formaldehyde is the most important aldehyde produced commercially, and is used in the preparation of urea-formaldehyde and phenol-formaldehyde resins. One source of… more
Abstract:A recent breakthrough in combustion stability analysis (UCDS) offers the means to accurately predict the combustion stability of a scramjet. This capability is very important due to the extreme scramjet operational environment, which makes cut-and-try development approaches impractical. With UCDS,… more
Abstract:Building upon the successful use of the Universal Combustion Device Stability (UCDS) process to resolve NASAs Ares I thrust oscillation issue, the proposed effort will optimize UCDS for application to the oxygen-rich staged combustion (ORSC) cycle under development by the Air Force. This will be… more
Abstract:Applying multivariable optimization in conjunction with modern materials technology has revealed an opportunity to dramatically improve flywheel energy storage technology. Using this innovative approach, GTL's Advanced FlywheelT could deliver 500 W-hr/kg with the potential to achieve in excess of… more
Abstract:To achieve the high propellant mass fraction (PMF) required by future high energy propulsion systems, light-weight propellant tanks are essential. GTL's Supra-tanksT can approach the theoretical performance limit for carbon fiber pressure vessels using cryogenic or room-temperature propellants. By… more
Abstract:This project will develop a prototype a federated search engine and web service for locating international science education research results based on supplied query terms. This prototype system will provide capabilities that will expand the functionality currently being developed for… more
Abstract:Government digital libraries ¿ such as the DOE¿s Office of Scientific and Technical Information¿s Information Bridge, Energy Citation Database, and other resources ¿ have a unique opportunity to facilitate communication between scientific communities of common interest. This project will add… more
Abstract:Today, a gap exists in reporting web metrics. Standard metrics tools do not have the ability to combine information about web resources with product-level details, such as the number of full-text downloads or specific user queries. This project will develop a prototype web metrics analysis system… more
Abstract:DESCRIPTION (provided by applicant): OptiPush Wheelchair Training System Wheelchair users are over twice as likely to be obese as people in the general population. The solution to obesity in the wheelchair user population is the same as it is in the gener

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.
