The geotechnical properties of municipal sewage sludge, in particular those pertinent to the handling and landfilling of the material, are presented. Index, drying, compaction, shear strength and consolidation tests were conducted on the material at different states of biodegradation. The organic content and specific gravity of solids were found to be(More)
Nest survival may vary throughout the breeding season for many bird species, and the nature of this temporal variation can reveal the links between birds, their predators, and other components of the ecosystem. We used program Mark to model patterns in nest survival within the breeding season for shorebirds nesting on arctic tundra. From 2000 to 2007, we(More)
In February 2007, the U.S. Department of Energy, BP Exploration (Alaska), and the U.S. Geological Survey, collected the first open-hole formation pressure response data in a gas hydrate reservoir (the “Mount Elbert” stratigraphic test well) using Schlumberger’s Modular Dynamics Formation Tester (MDT) wireline tool. As part of an ongoing effort to compare(More)
Field symptoms of transplanting shock in Eucalyptus nitens open rooted (1/2 + 1/2) transplants suggest water stress. To identify stages in the development of symptoms, changes in water relations were monitored from undisturbed seedlings growing in a commercial nursery through lifting, transplanting into pots and re-establishment of normal water relations.(More)
This collaborative effort to compare the world’s leading gas hydrate reservoir simulators is designed primarily to exchange information and insight that will lead to the improvement in simulation capability of experimental and naturally occurring gas hydrate accumulations. The initial phase of the code comparison activity achieved the simulation of five(More)
Economic studies on simulated natural gas hydrate reservoirs have been compiled to estimate the price of natural gas that may lead to economically viable production from the most promising gas hydrate accumulations. As a first estimate, large-scale production of natural gas from North American arctic region Class 1 and Class 2 hydrate deposits will be(More)
We have modified the surfaces of glass and Si(100) with 3-aminopropyltrimethoxy silane, a fourth generation amine-terminated poly(amidoamine) dendrimer, and poly(diallydimethyl ammonium chloride) to facilitate adsorption onto colloidal gold particles (average diameter 3, 5, 12, and 22 nm). UV-vis absorption spectroscopy and atomic force microscopy monitored(More)
Bare-root seedlings of Eucalyptus nitens frequently exhibit water stress after planting resulting in leaf lamina damage and reduced leaf area. Two trials examined effects of root exposure and desiccation between lifting and transplanting on post-planting water relations, leaf retention and root growth. Plants with roots exposed on a glasshouse bench(More)
A site inspection of an embankment on the West Coast Main Line (UK) revealed a general deterioration of the embankment, significant movement of the trackside services and waterlogging and bulging along the embankment toe. The medium-height embankment, with side slopes at about 30 degrees to the horizontal, was constructed on natural sidelong ground and the(More)
