Na, Cl, K, Sc, V, Cr, Mn, Co, Ni, Zn,Hf, W, Ir, Au, Ta,
and Re -via INAA (instrumental neutron activation analysis)
and REE, Ba, Sr via RNAA (radiochemical NAA). The inclusions...
Extensive morphological and growth habit variations have been
reported for bitterbrush (Purshia tridentata), a widespread western
shrub frequently used in range revegetation projects. Hybridization
of this species occurs with cliffrose (Cowania stansburiana) at the
point of their overlapping range in Utah and is believed to be
responsible for expression of...
The two classic theories of the distribution of
cities in an urban system are the rank size rule
and central place theory. The rank size relationships,
as incorporated into G. K. Zipf's Principle
of Least Effort, is seen as the result of a balancing
of the opposing forces of urban...
A technique for solving efficiently the catenary problem encountered in surveying with tapes is presented. The theory of the catenary solution is outlined, and our technique is shown to solve correctly the catenary for all conditions. Analysis of error that compared the catenary correction to the more commonly used parabolic...
Proceedings of the 50th Annual Western Orchard Pest and Disease Management Conference, held January 14-16, 1976 at the Imperial Hotel in Portland, Oregon.
Ana1ysis of January to March samples of gaper clam larvae from Yaquina Bay, Oregon have established four hypotheses for further testing: 1) gaper clams have an approximately lunar cycle of spawning intensity with maximum production of larvae at the periods of greatest tidal amplitude, 2) the time required for development...

Between 1965 and 1975, four alfalfa variety test trials, which included 38 different varieties, were conducted at Redmond and Alfalfa by the Central Oregon Experiment Station. Two trials were completed and two are continuing. Hay yields averaged 6.79 and 5.39 tons per acre per year in the completed trials at...
A nutrient solution technique developed for wheat was used to
determine tolerance of rice cultivars to aluminum (Al) toxicity.
Pre-germinated rice seed was placed on top of a screen and allowed
to grow on the Al-free solution for 72-96 hours or until the primary
root was 2-3 cms long. Seedlings...
The Purpose of the Study: The major purpose of this study was to determine if there were differences among the opinions of participating employers, previous participating employers, and non- participating employers concerning cooperative vocational education,. The hypothesis that there is no significant difference among the mean scores for the three...
The Purpose of the Study
The overall purposes of this study were: (1) to identify and
analyze the attitudes of the school board members, vocational
teachers, non-vocational teachers, school administrators and career
education administrators toward career education; (2) to identify and
analyze the attitudes of the above five personnel groups...
The principal objective of this study was to identify
and investigate the underlying basis for variations in the
volumes of exports of U.S. winter pears during the 1947 to
1974 period. A number of factors thought to be of importance
in the determination of the volume of exports of a...
Introduction. The study was conducted in response to a need
for systematic analysis of the practice of granting academic credits
for prior off-campus learning. It was stimulated by a commitment
to the goal of facilitating student development and an interest in the
theory that such development can be enhanced through...
Purpose of the Study
The purpose of the study was to determine whether there were
significant differences in students' career maturity as a result of
exposure to the concepts of career education. The study evaluated the
relative effectiveness of a developing comprehensive career education
project to help students attain increased...
Unit cell or pin cell calculations form the basis for
most nuclear core modeling. Because of this, it is of primary
importance to perform these unit cell calculations
accurately.
The subject of this thesis is the analysis of one of
the major approximations made in unit cell modeling, the
infinite...
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...
