Abstract:AJT proposes to develop a low-cost, engine test-stand system for small (500 pound) thrust engines using gaseous, liquid or cryogenic propellants. This test stand would incorporate automated propellant transfer and automated propellant line purge systems. The engines would be configured to a standard… more
Abstract:Precursor materials for superconductors such as Nb3Sn and Nb3Al include low melting point components. Therefore, conventional extrusion processes with large area reductions are not possible because adiabatic heating raises the temperature above the melting point. In certain circumstances,… more
Abstract:60275 Preliminary designs for the next generation of high energy physics colliders will require much higher magnetic field levels for successful operation. Currently available superconducting materials are either unable to reach these levels (NbTi) or they are much too expensive (Nb3Sn, Nb3Al… more

Abstract:DESCRIPTION (Adapted from the application): Penicillin-resistant bacteria pose
a serious threat to human welfare. This project will generate new products
designed to defeat resistant microorganisms. The most prevalent cause of
bacterial resistance involves the destruction… more
Abstract:DESCRIPTION (Verbatim from the Applicant's Abstract): The applicants will
develop statistical SURFACE fractal dimension (S-fd) features, which will
discriminate benign from malignant breast masses on MRI and mammographic
images. S-fd features derived from three… more
Abstract:It is proposed to develop novel eddy current probes based on spin dependenttunneling (SDT) magnetoresistive (MR) sensors to enhance the probability ofdetection of cracks within the bore of installed Taper Lok fasteners. Preliminaryresults show that the use of shaped excitation coils, together with… more
Abstract:DESCRIPTION (provided by applicant): "Drug addition is a complex illness. It is
characterized by compulsive, at times uncontrollable drug craving, seeking, and
use that persist even in the face of extremely negative consequences." As a
consequence of the extraordinary personal,… more
Abstract:DESCRIPTION (Scanned from the Applicant's Abstract): The specific aim of this
esterase (CE) inhibitor in an acute cholesterol absorption assay. Hamsters will
be gavage fed 3H-labeled cholesterol with CE-inhibitor ranging from 20-200
umoles. Twenty-four hours later, hepatic and… more
Abstract:DESCRIPTION (provided by applicant):Millions of Americans are infected by the
hepatitis B virus (HBV)-many of whom have no reason to believe they are
infected. There is a need to track down America's millions of HBV victims-as
well as a corresponding need for innovative… more

Abstract:DESCRIPTION (provided by applicant): Identifying the roles of variable
individual genetic factors can revolutionize approaches to the diagnosis,
treatment, and prevention of human disease. Single nucleotide polymorphisms
(SNPs) are the most frequent DNA sequence… more

Abstract:DESCRIPTION (applicant's abstract): Some 45 percent of all approved cancer
products. Plants and microorganisms can be extremely useful in the production
these medicines or precursors for these medicines. Collectively, photosynthetic
plants and microorganisms have a broad array… more
Abstract:DESCRIPTION (Verbatim from Applicant's Abstract): A child dies of malaria every
twelve seconds. Hundreds of millions of all ages are infected annually. If
carried out aggressively, new initiatives for preventing and treating malaria
could soon save the lives of one-fourth of… more
Abstract:65584 To meet regulatory and personnel health needs, the Department of Energy (DOE) must monitor radioactive isotopes to determine real-time activity levels over long periods of time. Improvements in sensitivity over current detection systems are required to meet present and future regulatory and… more
Abstract:65458 Scintillation spectrometers, consisting of inorganic scintillation crystals coupled to photomultiplier tubes (PMTs), are an important element of nuclear and elementary particle physics experiments. Performance of the detection systems used in these experiments is often limited by the… more
Abstract:65689 For an increasing number of human diseases, smaller animals such as mice and rats can serve as effective models. Accordingly, high-resolution radionuclide imaging, such as positron emission tomography (PET), of small animals can contribute unique information. However, clinical PET scanners… more
Abstract:65526 Current and next-generation experiments in nuclear and particle physics require detectors with high spatial resolution, fast response, and accurate data. However, current technology limits advances made in these areas. This project will develop a position-sensitive detector that provides… 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.
