This proposed work will generate a targeted phosphate ester hydrolysis catalyst for agent denial. This catalyst will be targeted by conjugation to single stranded DNA. Characteristics of the catalyst will be determined, including ruggedness, targeting selectivity, and potential methods for deployment.

The task of computationally simulating the dispersion and/or neutralization of toxic chemical/biological (CB) agents, released from weapons of mass destruction (WMD), puts a very high demand on the capability of current generation computational dynamics(CFD) codes. Current advanced computational tools for WMD threat simulation fail to address all the necessary physics, do not incorporate emerging ...

Upon successful completion of the proposed program, an accelerant payload concept shall be developed and evaluated. The use of an accelerant payload allows the munitions system designer the capability to exploit a thermal target defeat mechanism, inaddition to coupling to traditional high explosive/fragmentation defeat mechanisms, to increase the overall target lethality. The use of a thermal ac ...

Improvements in configuration of potential thermobaric warheads are presented. Such improvements in configuration will allow faster mixing rates, resulting in a reduction in total reaction time. Higher reaction rates, and lower reaction times lead to more complete reaction of thermobaric fuels, which will cause thermobaric weapons to better engage enclosed targets and cause more extensive damage ...

The use of the Improvised Explosive Device (IED) has become a favorite weapon of choice against the U.S. and Iraqi military and civilian population during the current conflict in Iraq. The potential use of Weapons of Mass Destruction (WMD) as IEDs to increase the area of effect and intensity of the attacks is growing as is the possibility of spreading IED use around the globe. The wide spread av ...

Three concepts will be evaluated in order to achieve flow separation and penetration enhancement of Earth Penetrating Weapons (EPW). One concept addresses the merit of carrying fluid within the EPW. The other two describe new techniques addressing the generation of gases from the structure of the penetrator accompanied by energy release in the interface. Experimental as well as analytical effort ...

This effort creates foundations for highly automated simulation tools that predict warpage in printed circuit boards and assemblies (PCAs/PCBs) and chip packages. Our technique, MHS, provides core capabilities to automate warpage and other problems that were impractical until now. MHS extends a multi-representation approach the PI first conceived at Georgia Tech for CAD-CAE interoperability. This ...

Science based assessments of the response of systems and material to hostile nuclear environments require detailed verified material response and failure criteria for confident results. Consequently there is a need for the development of experimentaltechniques to measure low pressure equation of state parameters accurately and economically using radiation simulators. The development of a soft x- ...

The measurement of the variation of fluence from a Plasma Radiating Source (PRS) with polar angle is critical to the definition of the stimuli acting on an effects experiment using PRS diagnostics because in general experiments and diagnostics view thesource from different angles. The polar angle fluence distribution is controlled by the opacity of the pinch, which is a sensitive function of pinc ...

Present reflex triode (RT) design performance is limited by debris shield response. The shield designs were derived empirically to satisfy specific experiment requirements. Optimizing the RT design will double target dose. Debris shield deformation definesthe closest permissible location of the test object and therefore determines the maximum dose achievable. The deformation of the debris shield c ...
