The primary purpose of this study was to determine which factors related to adult 4-H volunteer empowerment in 4-H youth development settings. This study examined the relationship of adult 4-H volunteers’ perceived leadership styles of Oregon 4-H Youth Development Educators (YDE) to the adult 4-H volunteer sense of empowerment. In...
Greenway trails have become a popular way to connect communities, increase public health and provide ecosystem services. Urban forests provide similar and overlapping benefits as greenways but are often unknown and underfunded. Integrating urban forest management with greenway management could be a way to create synergistic benefits for the community....
Exercise training has consistently been shown to increase fat utilization during exercise, while conflicting results have been reported on the effects of sex and age on fuel metabolism during exercise. PURPOSE: The primary objective of this investigation was to compare fat and carbohydrate utilization during exercise among males and females...
Powdery mildew of hop (Podosphaera macularis) may cause economic loss due to reductions in cone yield and quality.
Quantitative estimates of crop damage from powdery mildew remain poorly characterized, especially the effect of late season
disease management on crop yield and quality. Field studies in Washington State evaluated cone yield,...

When precipitation falls on frozen soil, serious soil loss can
occur. In order to assign realistic probabilities to the occurrence of
this condition for use in predicting erosion rates over long time
periods, a technique for combining characteristics of precipitation and
air temperature records is applied to hourly wet season...

Internal waves are often observed to break close to the seafloor topography that generates them, or from which they scatter. This breaking is often spectacular, with turbulent structures observed hundreds of meters above the seafloor, and driving turbulence dissipations and mixing up to 10,000 times open-ocean levels. This article provides...
Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
The behavior of the shore crab Hemigrapsus oregonensis was assessed
with and without exposure to polychlorinated biphenyls (Aroclor 1260).
After describing the crab's behavioral repertoire, activity budgets were
developed from observations of the time crabs spent in 20 categories of
shelter use, posture, and activity while held in habitat replicas...

This research evaluated the ethics competencies which were
determined to be important to the curriculum of an ethics course for
students studying Nondestructive Testing and Welding Inspection. Data
were gathered from samples of American Society of Nondestructive
Testing Nationally Certified Level III's (N = 268), American Welding
Society Nationally Certified...
An important segment of outdoor recreational activity in
eastern Oregon is based on the harvest of deer. The deer population
can be altered in two ways. Rangeland, which provides feed and
cover for deer, can be improved through public or private investments
or hunting regulations can be changed. This study...
Evidence supporting the contribution of American high school
curricula to student transition from school to work was inconclusive.
Social science research indicated that high school programs had little
effect upon student achievement after leaving school. This study
developed a model to identify factors that influence the transition
from school to...
In Oregon, "Incompetent to Stand Trial (1ST) Patients" were observed to be increasing in number, remaining in the hospital longer, and costing more to treat. A study was designed to investigate variables that could be used to predict their length of stay at Oregon State Hospital. Data for thirteen independent...
This thesis describes the design of a baseband digital predistortion
architecture for radio frequency (RF) amplifier linearization. Existing amplifier
linearization techniques are first examined. The nonlinearity of an amplifier can
be characterized as amplitude-to-amplitude distortion and amplitude-to-phase
distortion. The distortion can be corrected by providing a predistorted driver
signal (both...
A classical biological control project was undertaken
against the filbert aphid, Myzocallis coryli (Goetze), in
western Oregon. Hazelnut orchards in Spain, France, and
Italy were searched for natural enemies of the aphid, and
a parasitic wasp, Trioxys pallidus Haliday, was imported,
quarantined, mass-reared, and released in Oregon orchards.
The wasp...
The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J. Andrews Detritus Input...
In the Northwest, two tree fruit production problems may be
related to the role of ethylene on plant growth and development:
flowers and developing fruits are subject to low temperature injury
during early spring, and to the low fruit set of 'Comice'. Ethylene
may be involved in influencing dormancy and...
The effect of heterozygosity on the phenotypic stabilities of six
morphological plant characteristics was studied in hybrid crosses of
two self-pollinated barley species Hordeum vulgare L., emend Lam.
and Hordeum distichum L., emend Lam. Experimental material
consisting of parents and their F₁ diallel progeny were grown at two
field locations...
The flow configurations around and the forces acting on a
circular cylinder with its axis parallel to a nearby plane boundary
and subjected to a uniform flow were investigated. The flow conditions,
which were perpendicular to the cylinder axis and parallel to
the plane boundary were investigated experimentally and theoretically....
The location of prune dwarf virus (PDV) and Prunus
necrotic ringspot virus (PNRSV) in pollen and seed
from infected and healthy sweet cherry trees pollinated
with infected pollen was investigated. Virus-like
particles were observed in the cytoplasm of pollen
grains from PDV-infected cherry trees using transmission
electron microscopy. No particles...
Objectives of this study were to determine differences in
herbage production of three seral stages of three habitat-types.
Field studies were conducted in 1967 and 1968 on the Squaw Butte
Experimental Range.
Twelve, 400-square-foot, paired exclosures were established
in each habitat-type. Herbage was clipped from four, 48-squarefoot
samples in one...
A procedure for model-assisted climate impact assessment is
developed. The approach combines data from observations and
atmospheric general circulation models (GCNs), and provides the basis
for a potentially valuable means of using information derived from
GCMs for climate impact assessments on local scales.
The first component of this procedure is...
Evaluation and sensitivity analysis of a soil-water---
atmosphere-plant simulation model, SWATRE, developed by
Feddes et al (1978) in The Netherlands was conducted.
The evaluation was performed with the observed data
obtained by Cuenca (1978) for three different irrigation
levels in UC82 variety tomato fields in Davis,
California. SWATHE requires about...
The sea offers a wide variety of potentially useful resources. Marine algae have been a rich source of structurally unique natural products showing diverse biological properties. The current need to develop new antifungal, antibiotic, anticancer and antiviral drugs has prompted intense research efforts into the discovery, isolation and structure determination...
Deterministic source signature deconvolution is applied to the
processing of marine wide angle and vertical profiler data with air-gun
sources. Optimum results are obtained with a source signature
measured by stacking the signal reflected from a relatively homogeneous
abyssal plain sedimentary environment. This eliminates the need for
the unstable inverse...
This thesis presents a procedure to identify and evaluate forest
arterial and collector networks. The procedure identifies those
decision criteria important in evaluating both the arterial and
collector networks and the specific facilities identified on these
networks. The procedure incorporates the decision criteria and results
from network and facility analysis...
