Abstract:QPM involves alternating regions of nonlinear material, such that efficient 3-wave mixing is achieved without conventional phase matching. If a practical implementation of QPM were developed, then harmonic generation (SHG/THG) from CO(2) laser radiation and mid-infrared (mid-IR) pumped optical… more
Abstract:Many scientific and commercial applications of nonlinear optics are frustrated by the lack of suitable nonlinear optical (NLO) crystals. It may be possible to significantly change this situation by altering the basic approach from conventional phase matching to quasi-phase-matching (QPM). QPM… more
Abstract:INDIVIDUALS WHO ARE BORN WITH MENTAL RETARDATION OR WHO SUSTAIN TRAUMATIC BRAIN INJURIES OFTEN ARE LEFT WITH COGNITIVE IMPAIRMENTS. THESE IMPAIRMENTS AFFECT THE INDIVIDUAL'S ATTENTION, ORIENTATION, MEMORY, VERBAL OR PERCEPTUAL ABILITIES, AND SOCIAL REASONING. PARTICULARLY, MANY INDIVIDUALS WITH… more
Abstract:After 20 years in the Resin Transfer Molding (RTM) industry and 5 years of subcontractor experience in Low Cost Composite Weapons (LCCW) with the McDonnell Douglas Missile Systems Company, we concur that process repeatability, process controllability and uneven wet-out are major process drawbacks to… more
Abstract:Market potential exists for the development of a video and print library of life care programs for older adults and caregivers. Research conducted by project staff indicates that by offering thesecommercially viable products, health care costs and loss of employment issues can be positivelyaffected.… more
Abstract:This project's objective is to develop a low-cost fuel nozzle structure that creates a fuel spray which originates from a rectangular or circular array of fuel and air nozzles. The resulting fuel spray will apear tooriginate from a two-dimensional source, in contrast to the presently used fuel… more
Abstract:The hallmark of AD is the formation of cerebral senile plaques, with amyloid beta protein (Abeta)as its principle component. There is ample evidence suggesting that complement activation within andaround plaques leads to local inflammation and direct damage to neurons. We have discovered thatAbeta… more
Abstract:Scars form after tendon injury. It binds the tendon and prevents it from gliding freely, resultingin diminished movement in a high percentage of patients. Prophylactic application of an agent thatinhibits adhesion formation would improve the outcome of these patients. We have developed a seriesof… more
Abstract:HIGH QUALITY PAPER, E.G., MAGAZINE PAPER, ACCOUNTS FOR MILLIONS OF TONS OF PRODUCT PER YEAR. A SIGNIFICANT PORTION OF THIS PAPER CONSISTS OF MECHANICAL PULP WHICH HAS CHARACTERISTICALLY WEAK FIBER STRENGTH. NEWER PAPER MACHINES AND PRINTERS DEMAND INCREASINGLY STRONGER PULP WHICH IS LEADING TO… more
Abstract:Biodetection requires a recognition mechanism for the analyte of interest. Receptors not only provide this recognition mechanism, but also make possible generic detection, for example, neurotoxins can be recognized by a representative array of human neuroreceptors. A serious drawback with using… more
Abstract:A FAMILY OF PLASMA ENZYMES NAMED AMINE OXIDASES CONTRIBUTE TO A LACK OF SURVIVAL OF HEMATOPOIETIC PROGENITOR CELLS IN VITRO BY OXIDIZING THE AMINES RELEASED INTO THE MEDIUM INTO CYTOTOXIC AND MUTAGENIC HYDROGEN PEROXIDE AND ALDEHYDES. THIS SHORT-TERM TOXICITY MANIFESTS AS LOW CLONING EFFICIENCIES.… more
Abstract:With the advent of cytokine therapy, thrombocytopenia is the major dose-limiting toxicity of anti-cancer and anti-AIDS drugs. Early screening of developmental agents for toxicity to hematopoietic, particularly megakaryocytic, progenitors would allow the selection of drugs that are effective against… more
Abstract:THE VULCAN LINEAR MOTOR CONCEPT PRINCIPLE HAS BEEN PROVEN IN HARDWARE APPLICATIONS INVOLVING STIRLING CYCLE REFRIGERATORS AND ELECTRICAL GENERATORS. THE VULCAN LINEAR MOTOR OFFERS SINIFICANT ADVANTAGES OVER THE MOVING COIL AND OTHER MOTOR TYPES COMMONLY USED IN CRYOCOOLERS. THE PROPOSED EFFORT WILL… more
Abstract:IAP will develop a technique to process nickel-titanium to obtain high performance Nitinol shaped memory alloys using dynamic compaction techniques. This approach may result in improved SMA properties such as recoverable stress and strain.
Abstract:Ship electirc drive require large currents at full power to develop the necessary horsepower to propel the ship. Coaxial lines are used to reduce the external magnetic fields to the transmission lines, and reduce ship magnetic signature. Flexible couplings must be used with coaxial lines to account… more
Abstract:As international markets become more open and competition between domestic and foreign companies grow, novel approaches for improving the efficiency of metal forming processes are required. This is especially true for low ductility classes of materials such as intermetallics and low ductility metals… more
Abstract:The specific product intended for development and distribution throughout the United States manufacturing society will be a software package to assist manufacturing managers, engineers, organizers, schedulers and other appropriate personnel with their suitable planning of low-frequency endeavors.… 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.
