In mid-December, 1948, during the time the crab season was closed in State waters, a boat caught crabs outside the entrance to the Columbia River, which was outside the three-mile jurisdictional limit. Because "one man was already fishing," the crab fleet members began to complain and threaten to fish before...
"Letters and newspaper articles concerning the low quantity and poor quality of Dungeness crabs in Nehalem Bay have been frequently received by the Oregon Fish Commission. Popular opinion usually places the blame for the lack of legal-sized bay crabs in the Nehalem estuary upon the adjacent commercial crab fisheries, A...
In early 2000, the Generation IV International Forum (GIF) was created to perform research and development for the next generation nuclear systems. Among the selected nuclear systems was the Very High Temperature Gas-Cooled Reactor (VHTR). Then in 2008, the U.S. Department of Energy (DOE) decided that the Next Generation Nuclear...
An approach for developing a computer-based aid to
assist in monitoring and assessing nuclear power plant
status during situations requiring emergency response has
been developed. It is based on the representation of
regulatory requirements and plant-specific systems and
instrumentation in the form of hierarchical rules. Making
use of inferencing techniques...
Silvicultural canopy gaps are emerging as an alternative management tool to accelerate development of complex forest structure in young, even-aged forests of the Pacific Northwest. I investigated patterns of nitrogen (N) availability along transects through 0.1 and 0.4 ha silvicultural gaps in three 50-70 year old Douglas-fir forests of western...
The effect of fluid axial thermal conduction on one-dimensional liquid metal natural circulation and its linear stability was performed through non-dimensional analysis, steady-state assessment, and linear perturbation evaluation. The Nyquist criterion and a root search method were employed to find the linear stability boundary of both forward and backward circulations....
Seismic refraction data collected in 1985 by the USGS were used in
this study to derive the P and S velocity structure of the crust beneath the
Gulf of Maine. The data quality differs among instruments and is affected
by surficial lateral heterogeneities, a ringy source signature and
reverberations. Velocity...
Algorithms for analyzing laser interferometry
signals were developed and adopted to the computer based
processing of small displacement measurements. These
methods, matrix operation approach and fixed parameters
approach, are based on signal phase calculation and are
able to replace complex fringe counting electronic
circuits. The matrix operation provides an approach...
The OSU/APEX thermal hydraulic test facility models the passive safety systems
of the Westinghouse AP600 advanced light water reactor design. Numerous experiments
have been performed to test these systems, the one of focus here is the station blackout
scenario. This experiment simulated the complete loss of AC power to all...
