Pump Outs, General and D0 Considerations

Description: Seal Pump Outs (PO) are provided by specifically designing and providing redundant, or double, seals to create an annular volume that can be '(vacuum) pumped out' to test the integrity of both seals. The value of the technique is most readily apparent in the construction of large piping systems or vessels whose closure is on a different schedule than the nozzle closures, or whose nozzles are serially closed. In the case of D0, for instance, the high voltage boxes were put in place and leak chec… more

[Cloning-idependent mapping technology for genomic fidelity, contig linking, C-DNA site analysis, and gene detection]. Final report

Description: The project was designed to develop and apply a novel unconventional approach to genome mapping based on physical properties of DNA that are a sensitive function of the base sequence, and so does not depend on the clonability of the sequences to be mapped nor on the presence of particular restriction sites. We have shown that a broad array of DNA fragments are retarded at nearly the same level in denaturing gradient gel electrophoresis (DGGE) if the segment with the lowest thermal stability has… more

Transportation Security: Issues for the 114th Congress

Description: This report examines aviation, transit and passenger rail security, as well as port and maritime security. The difficulty and cost of protecting the transportation sector from attack raises a core question for policymakers: how much effort and resources to put toward protecting potential targets versus pursuing and fighting terrorists.

Slag characterization and removal using pulse detonation for coal gasification. Quarterly research report, October--December, 1995

Description: Experiments will mainly focus on breaking the bonds within the slag itself using detonation wave. For the experiments, initial suggestion was to build up slag deposit around a representative tube by placing it inside the convection pass of an actual boiler at the Northern States Power Company. But it was later concluded that once the tube is cooled to room condition, the thermal stress will greatly reduce the bonding between the heat transfer surface and the slag. It was concluded that the slag… more
