Two experiments were conducted using coturnix quail to determine
the effects of dieldrin and calcium on the reproductive performance
of this species. In both experiments quail were raised on a
soybean-meal glucose-monohydrate ration. At 25% egg production
the quail received diets containing 0, 10 or 25 ppm of dieldrin in...
Efforts are continually being made in remediation surveys to reduce the time and manpower required to perform work while maintaining the ability to detect low levels of contamination. To this end, organizations are utilizing portable instrumentation in conjunction with global positioning systems (GPS). This combination of technologies allows a surveyor...
The genus Ochodaeus Serville contains approximately sixty
species and is World wide in its distribution. One-half of these
species are known from the Nearctic and Neotropic regions.
Adults of six previously described species common to the
United States have been studied in detail. The mandibles, stridulatory
peg, and male genitalia...
When land use issues are voted upon directly by the people, or by
the legislators who represent them, the outcome often reveals a discrepancy
based on population density. Urban-suburban areas tend to
support regulation, while rural areas tend to oppose it. The residents
of Clackamas County have voted on two...
A modeling study is undertaken to better understand the physics of katabatic flows. This study is divided into three topics; a comparison between a large eddy simulation (LES) and a mesoscale model of katabatic flows, a sensitivity study of katabatic flows to various physical parameters, and an investigation into the...
A model was developed for analysis of the soil water balance of
individual reforestation sites in western Oregon. The numerical
procedure for this model was programmed in compiled BASIC language and
calculations for an entire season are made in about 180 seconds on an
IBM AT microcomputer.
The processes that...
A case study was performed in 2000 and 2001 to characterize the thermal pattern of four morphologically similar eastern Oregon streams and to identify the physical and environmental factors that expressed significant and functionally viable relationships with stream temperature (daily maximum, daily minimum and daily rate of heating). Stream and...
The transfer of trace metals within an estuarine
system is a complex function of physical and chemical processes
unique to that system. Although interactions of
metals with individual components has been studied, there
has been little investigation of interactions with multiple
component systems. Thus to further understand these
processes, an...
An experimental biomass combustion facility has been
built and established at Oregon State University. The
furnace, or Biomass Combustion Unit ( BCU ), uses an augertype
fuel feed system, grate-type fuel support with under
and over fire air supply.
Fourteen pellet species from five States - Alaska,
Washington, Oregon, Idaho,...
