A prototype real-time process monitoring emergency
classification expert system, RT/EM-CLASS, has been developed
for use at the Trojan Nuclear Power Plant. This knowledge-based
system features the integration of electronically sensed plant
data with the menu selection data representation of its
predecessor, EM-CLASS. This prototype demonstrates the
techniques required to acquire...
The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
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...
Genetic diversity of two salmonid species, Dolly Varden (Salvelinus malma) and coastal cutthroat trout (Oncorhynchus clarki clarki) in Prince William Sound, Alaska were examined at multiple spatial scales with three molecular markers. Pleistocene glaciers covered what is now Prince William Sound 8,000- 12,000 years ago and both species colonized the...
The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...
Glutathione (GSH) is the predominant low molecular weight thiol antioxidant
in liver tissue. GSH plays an important role in maintaining the intracellular thiol redox
ratio as well as detoxification of electrophiles and xenobiotics. Aging leads to a significant decline (35%; P ≤ 0.05) in hepatocellular GSH levels. Using young (2-4...
This research project compared teacher attitude using
the Pupil Control Ideology Form with student attitude using
the Arlin-Hills Student Attitude Survey. P.C.I. Forms
were collected from 834 teachers from 95 elementary Christian
schools in several states. A total of 1074 student
attitude surveys were collected from Christian school students
in...
The enzymes and pathways involved in the catabolism of
glucose by several strains of Streptococcus diacetilactis, Streptococcus
cremoris, and Streptococcus lactis, commonly called the
lactic streptococci, were studied. The presence of aldolase,
triosephosphate isomerase and alcohol dehydrogenase in these
organisms provided evidence for the operation of the Embden-Meyerhof-Parnas (EMP) pathway...
