Abstract:Accurate measurement of gastrointestinal absorption of various substances is important in bothresearch and diagnosis. In many cases, the acceptable general approach is the balance procedure. Thisprocedure suffers from the requirement for complete collection of stools over an extended period oftime.… more
Abstract:1We are proposing a computerized tomographic (CT) dimensional measurement system that will remedy two of the major problems experienced by current methods: the distortions caused by CT artifacts, and the blurring caused by the system point - spread function (PSF). The distortions resulting from data… more
Abstract:Instrumentation that can provide microstructural characterization of medical grade polymers,fabrics, and composite materials is the proposed research's long term goal. One micron resolutionvolume computed tomography of test specimens can now be demonstrated by combining anNIST-developed x-ray… more
Abstract:We will adapt a non-cryogenic magnetic field sensor previously developed for defense purposesand apply it to magnetocardiography (MCG), the measurement of magnetic fields induced by electricalcurrents in the heart. As a single non-invasive sensor, this unit would have similar applications to… more
Abstract:The proposed innovation is to apply differential phase acoustic microscopy to NDE inspection of ceramic Sn3N4 ball bearings. Differential phase acoustic microscopy is more sensitive than standard acoustic microscopy, and can provide the location and size of defects, which is a specific goal of the… more
Abstract:We propose a method of generating x-rays that will combine high instantaneous output of rotating-anode x-ray tubes with continuous cooling rates as great or greater than fixed-anode tubes. This combination can be achieved in a mechanically simple way, and will reduce spot wobble without vacuum seals… more
Abstract:We have generated a monoclonal antibody, B6B21, and have shown that it significantlyenhances acquisition rates in hippocampus-dependent trace eyeblink conditioning in rabbits, halving thenumber of trials required to reach 80% conditioned responses. Previous studies, with a variety of modelsystems,… more
Abstract:We will develop a computer simulation of the critically ill patient for use in training medical students, residents, nurses, fellows, and physicians. This computer software will faithfully simulate the functional aspects of cardiopulmonary physiology, using state-of-the-art mathematical models. For… more
Abstract:We propose to develop a general purpose computer code for calculating the scattering from antennas on an aircraft, which is described by a CAD file. The scattering contribution will include both the passive structure mode and active irradiation mode, calculcated by a hybrid of a high-frequency ray… more
Abstract:Elderly women and men are at higher risk for developing skin cancers, as a result of theirincreased cumulative exposure to ultraviolet radiation, and their depressed immune system functioningrelative to younger persons. Interactive multimedia materials providing information about skin lesionsand… more
Abstract:The incidence of skin cancer is increasing at a high rate. Skin cancers are uniquely suited forprevention and early detection interventions in that adequate sun protection can prevent occurrence andscreening can reduce morbidity and mortality. This interactive multimedia program is intended… more
Abstract:U.S. ARMY CECOM HAS IDENTIFIED THE NEED TO DEVELOP AND DEMONSTRATE IMPROVED TRANSPORT TECHNOLOGIES FOR MULTIMEDIA C3 COMMUNICATION SYSTEMS. BENEFITS TO BE OBTAINED INCLUDE ENHANCED SECURITY AND ANTI-JAM SURVIVABILITY, HIGH DATA FLOW EFFICIENCY AND GREATER USE OF WIRELESS TO REPLACE HARD CABLED… more
Abstract:Flavonoids ar plant substances that give flowers and fruits their color, and they are included ina normal diet. The isoflavones are a class of flavonoids found in soybean. Epidemiological studies haveshown that in geographic areas where diets are rich in soybeans there is a reduced incidence of… more
Abstract:A new software tool is proposed for the optimal design of materials processing equipment. The objective of the project is to combine fluid flow, heat transfer, and mass transfer simulation capabilities with advanced numerical optimization techniques to automate the design of microgravity experiments… more
Abstract:RESEARCH WILL BE CONDUCTED BY HICHEM CORPORATION, TO DEVELOP A NEW TECHNOLOGY FOR PYROLYSIS OF SCRAP TIRES. DISPOSAL OF USED TIRES IS A BIG PROBLEM IN THE WORLD, ESPECIALLY USA, SINCE MORE THAN 2.5 MILLION TIRES ARE DISCARDED EACH YEAR. MOST OF THESE TIRES ARE DISPOSED IN LANDFILLS. PYROLYSIS OF… more
Abstract:Hip fracture in the elderly (90% occur after age 70) claims 250,000 victims/year in the U.S. andcosts 6 to 12 billion dollars. Over 90% of cases result from fall-related hip impact in elderly personswith brittle bones. Medical therapy, fall prevention and exercise are only partially protective.… more
Abstract:PDQ (Physician Data Query) is a set of related files produced by the National Cancer Institute,International Cancer Information Center and available online on CD-ROM, via facsimile (subset) and viaInternet (subset). PDQ contains information on the diagnosis, prognosis and treatment of cancer. PDQis… more
Abstract:SNOW AVALANCHES THREATEN LIFE, PROPERTY, FORESTS, AND TRANSPORTATION SYSTEMS. AVALANCHE DESTRUCTION OF CRITICAL AREAS IS PREVENTED BY RELEASING SMALLER AVALANCHES UNDER CONTROLLED CONDITIONS. THE PROPOSED PROGRAM IS FOR THE DEVELOPMENT OF THE ACOUSTIC TRANSDUCER AVALANCHE CONTROL SYSTEM (ATACS), AN… 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.
