Abstract:Our clean-sheet-of-paper architectural concept is different from any used by the Navy at either UHF or EHF. It takes advantage of the unique attributes of DSCS space and ground segments, compared to other MilBatcom systems. Still, our innovative networking concept is compatible with current and… more
Abstract:This Phase I proposal describes a low cost, two-way satellite data link for retrieval of broadband environmental data from remote sensor sites at sea. The proposed approach uses existing space resources providing a mix of low and high bandwidth users with data rates up to 100 bps per user. Thousands… more
Abstract:This proposal describes an appproach to developing a very low cost satellite modem providing an economical, useful measure of anti-jam performance for SHF (DSCS) or commercial (C or Ku band) satellite communications. Our proposal presents the top level system issues and outlines a plan for Phase I… more
Abstract:A MULTIMEDIA-BASED LEARNING ENVIRONMENT FOR 8-12TH GRADE EARTH SCIENCE EDUCATION WILL BE CREATED ON CD-ROM AND VIDEODISC. THE SYSTEM CONSISTS OF A VISUAL DATABASE DELIVERED IN BOTH ANALOG AND DIGITAL FORMATS, DETAILED LESSON PLANS, AND TEXTUAL SUPPORT MATERIALS. THE SYSTEM WILL PERMIT THE GRADUAL… more
Abstract:Leading edge vortex flap modifications are proposed for improvedlow-speed lift and L/D characteristics of supersonic cruiseaircraft. The aim is to increase the vortex-lift potential inaddition to generating vortex thrust on highly-swept wingconfigura
Abstract:HIV is a significant problem worldwide. Considerable effort is being made to develop a vaccinewhich elicits high titers of neutralizing antibodies, which have been correlated with long term protection.The investigators have devised a novel, dual carrier conjugate vaccine. They anticipate it will… more
Abstract:The cotton rat has been used in biomedical research since 1937, when it became the first smallanimal model of endemic typhus. Since then, it has been shown to be susceptible to infection by aremarkably wide spectrum of human and rodent pathogens. Of greatest current interest is its use asa model of… more
Abstract:This project is designed to explore the feasibility of the development of a small, compact(lunchbox size), stand-alone and rapid infant hearing screening instrument that utilizes a two levelscreening technique. The first level of screening used an automated otacoustic emissions test for a veryquick… more
Abstract:The majority of viral vaccines establish a state of systemic protective immunity by injection oflive attenuated or inactivated virus preparations. The use of injectable vaccines has reduced theincidence of many viral diseases. Nevertheless, their usage is associated with some undesirable sideeffects… more
Abstract:Modern molecular biology has provided us with a means of producing immunogens withunprecedented ease and precision, but these new methodologies generate purified immunogens that donot generally induce a strong immune response in the absence of an effective adjuvant. Thedevelopment of improved… more
Abstract:Vibrio cholera and Typhi salmonella are human pathogens that colonize gut and elicit bothmucosal and systemic protective immune responses. Novel HIV1 prophylactics will be developed usinggenetically attenuated strains of these organisms to derive single dose oral HIV1 vaccines. These neworal… more
Abstract:At least fourteen companies are developing new corneal shaping refractive surgery procedures.In addition to these emerging technologies, conventional surgical techniques are also being used tomodify its shape. Three dimensional shape information about the cornea is critical to planing andmonitoring… more
Abstract:The intraperitoneal injection of insulin-producing islets, immunoprotected by an alginate-polyam-ino acid membrane, is a potential method of reversing diabetes without the need for life-longimmunosuppression. Using alginate high in guluronic acid content, we have successfully reverseddiabetes in the… more
Abstract:The proposed projet is to prove the universal capabilities of the Expert Sensor technology by applying it to a novel chemical sensor suite composed of an array of the newly developed porous silicon chemical sensors. The Expert Sensor architecture provides a standard intelligent interface between… more
Abstract:IT IS CLEARLY RECOGNIZED BY THOSE ASSOCIATED WITH ENVIRONMENTAL RESTORATION THAT COAL-FIRED BOILER FLYASH IS A SIGNIFICANT CONTRIBUTOR TO THE INCREASING SHORTAGE OF LANDFILL AVAILABILITY. IN GENERAL, THE LANDFILL REQUIREMENTS FOR SOLID WASTE PRODUCTS ARE BECOMING A MAJOR ENVIRONMENTAL AND ECONOMIC… 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.
