Long-term oceanographic and meteorological data were used to develop models that describe the observed variation in the recruitment of Pacific mackerel (Scomber japonicus) in the California
Current region. The models that were found to best describe recruitment included both density-dependent factors and environmental factors. Models incorporating only density-dependent factors
accounted...
Rural areas tied to natural resource-based economic activity are encountering
difficulties in preparing for economic growth and development.
An important problem facing local officials of such an area, Union County,
Oregon, is the identification of county characteristics that may induce
the expansion of local businesses and location of new plants....

Pandalis jordani Rathbun, like many other species of pandalid shrimps, undergo regular diel changes in their vertical distribution (Tegelberg and Smith 1957; Alverson et al. 1960; Pearcy 1970, 1972; Robinson in press). Little is known, however, about the vertical distribution and diel migrations of larval and juvenile shrimp, or at...
In recent years almost all states have legislated educational
and licensing programs to protect the welfare and property of citizens
engaged in outdoor recreational pursuits. Such programs exist
for automobile, motorcycle, airplane, and snowmobile operators.
However, boating continues to be one of the major recreational outdoor
activities where operators of...
The Farm Enterprise Committee of the Confederated Tribes of
the Umatilla Indian Reservation requested that an evaluation be made
of the Reservation land resource for the purpose of acquisition by the
Tribe as a part of a study of the feasibility of an expanded farm
enterprise. The Committee's primary goal...
The necessity for the evaluation of training methods on a between
methods basis is suggested. Current methods of training evaluations
are considered, and found to be generally deficient for their
lack of between technique comparisons. The necessity for an outline
of planned comparative analysis of training methods is indicated and...
The results of an experimental and analytical study of deep
submerged multiple-port thermal discharges are presented. The
experimental results include the measured downstream thermal dilution,
width, and centerline trajectory of the buoyant thermal
plume from multiport jets. Independent parameters for which
measurements were obtained include port spacing, discharge Froude
Number,...
The concept of a process is often used in connection with operations
of parts of a computer system. This thesis discusses processes
in terms of their use as representations of a physical object or system.
Five primitives are introduced as operators for allowing processes
to be run in a piecemeal...
Facility location studies involve the selection of a preferred
course of action from an array of multiattributed alternatives. The
factors affecting this selection are defined in both quantifiable and
qualifiable terms. The former comprises primarily monetary or operational
data, and the latter consists of nonmonetary and environmental
parameters; where the...
The feasibility of fluidized bed combustion of coal for commercial
and industrial steam power generation has been established
and reported in the literature. Satisfactory removal of sulfur
oxides from the combustion product gases has also been reported.
In this experiment various heat exchanger tube patterns,
of commercial size tubes, were...
The purpose of this study was to determine if male and female
Counselor-Trainees enrolled in master's degree programs in the
State of Oregon would emit significantly different responses to a
new and professionally developed video-based client simulation.
The sample consisted of ninety-two Counselor-Trainees
enrolled during the 1975-76 academic year in...
An interesting means of shoal removal has recently been implemented by the U.S. Army Corps of Engineers for use in shallow Pacific
Coast tidal inlets and estuaries. In the past, removal of shoaled material has consisted of physical excavation of material, transportation from the site, and placement in a spoils...
A model of a squirrel cage induction machine, d.c.-
link power supply and centrifugal pump is developed and
used in the design and evaluation of a perturbation feedback
control system for a sewage pumping station. A comparison
of the simulation model of the induction machine
and a laboratory machine to...
