Model–data comparisons of plant physiological processes provide an understanding of mechanisms underlying vegetation responses to climate. We simulated the physiology of a pi~non pine–juniper woodland (Pinus edulis–Juniperus monosperma) that experienced mortality during a 5 yr precipitation-reduction experiment, allowing a framework with which to examine our knowledge of drought-induced tree mortality....
The use of advanced concepts can make the nuclear fuel
cycle more efficient by allowing pins to be operated at
high powers and to higher burnups. Among the more
promising concepts in advanced fuels is sphere pac fuel.
In a first attempt to bring together models describing
individual phenomena, the...
Alzheimer's disease, a chronic and irreversible form of
dementia, has been recognized as one of the most critical
medical-social-economic problems facing our country. As
Alzheimer's disease and other related dementias progress,
the patient becomes increasingly dependent upon family and
natural support systems to provide care. This dependency
can place the...
In 1979, the Geographic Applications Laboratory
of the Department of Geography, Oregon State University,
was retained by the Portland General Electric Company to
form and supervise a program to monitor the bioenvironment
in the vicinity of the Boardman Coal-Fired Power plant. This
partially fulfills requirements of the Department of Energy...
Signal crayfish Pacifastacus leniusculus were studied in Lake Billy
Chinook, Oregon, during 1994 and 1995. Because little was known about the
crayfish population, this study was conducted to obtain reliable estimates of life
history and population parameters, document historic commercial harvests, and
make management recommendations. Crayfish were captured with baited...
