Unfortunately, the weapons currently available to the DoD do not offer a way for the WMD to be destroyed without risking the spread of that material throughout the area. The strategy for the defeat of biological weapo ...

At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrom ...

DESCRIPTION provided by applicant Although tyrosine phosphorylation is an important controlling element in cell signaling no tRNA suppressor for phosphotyrosine pTyr incorporation has yet been made We propose to use directed molecular evolution of several aminoacyl tRNA synthetases aaRSs to identify mutations that enable binding of pTyr to the aaRS Specifically ATP molecules will be att ...
