Non destructive evaluation of metallic, spherical pressure vessels is crucial to the safety and operations of a plant due to the large volume of hazardous products stored at high pressures. Sizes of such spheres vary and diameters may range from 10 to 25 meters, even more, while total length of welds can be hundreds of meters. Additionally, accessibility(More)
Poly(ADP-ribose)polymerase-1 (PARP-1) is a highly abundant chromatin-associated enzyme present in all higher eukaryotic cell nuclei, where it plays key roles in the maintenance of genomic integrity, chromatin remodeling and transcriptional control. It binds to DNA single- and double-strand breaks through an N-terminal region containing two zinc fingers, F1(More)
Landfills have the potential to mobilize arsenic via induction of reducing conditions in groundwater and subsequent desorption from or dissolution of arsenic-bearing iron phases. Laboratory incubation experiments were conducted with materials from a landfill where such processes are occurring. These experiments explored the potential for induced sulfate(More)
We introduce a simplified model for thin layer flows of granular materials with yield. The model is derived from a Drucker–Prager rheology, and describes the dynamics of the velocity profile and of the transition between static and flowing material. We compare the analytical solution in the inviscid case, and the numerical solution in the viscous case, to(More)
This panel will present initial findings on the design, pilot implementation and research of TeamRoom, an innovative Louts Notes application. The application was designed initially to support temporary task teams and was extended to support ongoing , distributed and co-located work and management teams. TeamRoom represents early exploration into the(More)
The Environmental Monitoring and Assessment Program (EMAP) is an interagency effort coordinated by the U.S. Environmental Protection Agency and designed to collect information to assess the condition of the nation's ecological resources. The Information Management System for EMAP was developed to capture, preserve, and provide to users data and information(More)
1 Abstract—The seismic signals generated by two large volcanic debris avalanches (Montserrat, Lesser Antilles, 1997 and Mount St. Helens, USA, 1980) and a large rock-ice avalanche (Mount Steller, USA, 2005) have been analyzed. For the two debris avalanches, given the times and locations of such landslides, their signals were recorded by only a few seismic(More)
ACKNOWLEDGMENT The author would like to express his sincere appreciation to Dr. Robert E. Fulton for providing me with the unique opportunity to conduct research in the area of information management while supporting a family. His encouragement and confidence will always be valued. I would like to thank James J. Duhig, Jr. of the Atlanta Electronic Commerce(More)
