Wild type (wt) dengue 1 viral RNA will be used as substrate to generate a complementary DNA (cDNA) library of clones that contain identified and sequenced DNA segments spanning the entire dengue 1 genome. Point mutations designed to generate amino acid alterations will be introduced at the nucleotide level in the cloned dengue 1 DNA sequences by polymerase chain reaction amplification. These mutat ...

An automated electrical load management system to provide load shedding during periods of high demand is required for adaptation to the V-22 Tilt-Rotor aircraft. A low cost and flexible system is required in order to extend current mission capabilities without significant overhaul of the electrical power system. Three steps toward solving this problem are: 1) determination of electrical load shedd ...

Changes in the world political situation from a U.S.-Soviet bipolarity to a new multipolar world have resulted in a change to the U.S. national military strategy. In this post-Soviet world, U.S. forces will be presented with not only expanded regional conflicts among Third World countries but also an increased nuclear, chemical, and biological (NBC) weapons threat in terms of diversity and frequen ...

Imaging bundles of infrared fibers will be developoed for use in an IR scene generation system. The fibers will be made from zirconium fluoride glass for the 3-5 micron region, and chalcogenide glass for the 8-12 micron region. Low loss chalcogenide glass fibers will be developed by improving the perform and fiber processing techniques, and using high purity starting materials and glasses. In part ...

The rapidly changing military signal environment has reduced the probability of detecting and correctly identifying signal emitters with conventional signal analysis techniques. Increasingly complex waveforms covering large spectral band-widths are now being used. In addition, the number of active emitters has increased dramatically. Coupled with this rapidly rising processing load is the use of t ...
