Abstract:CURRENT SAMPLE SPINNERS FOR NMR SPECTROSCOPY ARE GENERALLY LIMITED IN ROTATIONAL SPEED TO ABOUT 10 KHZ. RESEARCHERS EXPECT TO DEMONSTRATE A SAMPLE SPINNER THAT IS CAPABLE OF STABLE OPERATION AT SPEEDS TO 40 KHZ. THE DEVICE WILL SIGNIFICANTLY IMPROVE THE RESOLUTION CAPABILITY OF SOLID STATE NMR BY… more
Abstract:IMPROVEMENT IN THE QUALITY, SIZE, AND COST OF INDIUM PHOSPHIDE (INP) SINGLE CRYSTALS IN NECESSARY IN ORDER TO REALIZE THE HIGH PERFORMANCE BENEFITS OF INP-BASED MICROWAVE AND MILLIMETER WAVE MONOLITHIC INTEGRATED CIRCUIT TECHNOLOGY. TO MEET THIS NEED, RESEARCHERS ARE DEVELOPING A NOVEL MODIFICATION… more
Abstract:THIS PHASE I PROJECT ADDRESSES THE NEED FOR ROBUST, CONTAMINATION-FREE CIRCULATORS TO DISTRIBUTE LIQUID OR SUERCRITICAL HELIUM THROUGH SUPERCONDUCTING MAGNETS. AN ADVANCED CENTRIFUGAL MACHINE SUITABLE FOR LIQUID OR GAS CIRCULATION AT CRYOGENIC TEMPERATURES WILL BE DEVELOPED. THE MACHINE INCORPORATES… more
Abstract:RESULTS OF A NATIONAL STUDY ON HEAD START RECRUITMENT AND ENROLLMENT PRACTICES SUGGEST THAT THE INCREASING CULTURAL DIVERSITY IN THE NATION CREATE NEW CHALLENGES FOR PROGRAMS AS THEY CONTINUE TO REACH OUT TO THOSE FAMILIES IN GREATEST NEED OF SERVICES. AS THE POPULATION SHIFTS, SO WILL THE NEEDS OF… more
Abstract:We will research, design, and produce written materials and create a technical assistance outreach plan for reaching commercial and public television producers with information to support the production of children's television programming with AIDS/HIV information and messages. RMC plans to apply… more
Abstract:The proposed research addresses the problem of online authentication of a talkers identity using techniques borrowed from text-independent speaker identification. The proposed investigation will develop a basis for a Phase II, real-time system effort suitable for operational testing. The proposed… more
Abstract:In the production of large, complex therapeutic proteins, animal cells are preferred as the biocatalyst. Various types of production bioreactors are employed including deep-stirred and sparged tanks (with or without microcarriers), cell-immobilizing matrices, and fluidized beds of porous… more
Abstract:A new textile process has been developed by Techniweave that employs multidirectional weaving in the fabrication of integrally woven, net shaped, complex components. The process has been demostrated manually and has been shown through design of equipment to be feasible for an automated system. The… more
Abstract:MISSILE SEEKERS MUST DETECT TARGETS IN DUAL BANDS (3-5 UM AND 8-12 UM). THEY NOW USE HYBRID ASSEMBLY OF TWO SEPARATE ARRAYS, WHICH INCREASES THE POWER, CONSUMPTION, THE WEIGHT, AND THE COST. WE WILL DEVELOP MONOLITIHIC DUAL BAND 128X128 STARING ARRAYS ON HGCDTE MATERIAL. THE INNOVATION IS THE… more
Abstract:THE EMERGENCE OF VLSI TECHNOLOGY HAS INCREASED THE COMPLEXITY OF INTEGRATED CIRCUIT DEVICES, IN TERMS OF TRANSISTORS PER DEVICE, AT A RATE MULTIPLYING BY 100 EVERY 10 YEARS. NEW TECHNOLOGIES, SUCH AS SURFACE MOUNT, REQUIRE SPECIAL TECHNIQUES TO MAKE THE BOARDS TESTABLE. THE GOAL OF THIS RESEARCH AND… 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.
