This study data from the Alsea Watershed Study located
approximately ten miles from the Pacific Ocean in the Oregon Coast
Range. The purpose was to evaluate the effects of roadbuilding on
storm flows in two experimental streams. One 138 acre watershed,
Deer Creek II, was subjected to 3.5 percent treatment...
The vegetation surrounding a nest shades and insulates the incubating
bird in addition to concealing it. The vegetative material
that makes up a nest insulates the eggs from its warmer or cooler
surroundings. Since a Killdeer builds a stone-lined nest on barren
ground, both egg and adult are subject to...
This paper describes the analysis of data from a three-year gross time study of skyline, balloon, and helicopter yarding systems operating in Western Oregon. Data collection activities were designed and supervised by the Pacific Northwest Forest and Range Experiment Station, U.S.D.A. Forest Service. The specific logging systems studied were running...

Establishment of a non-native plant species in new habitats beyond their native range is associated with inherent changes in ecosystem properties. These changes may be dramatic or subdued, and consequences may be positive or negative depending on characteristics and response of the resident ecosystem. Non-native aquatic plant species in the...
Coastal marsh vegetation is an important component in maintaining marsh stability that is threatened by changes in sedimentation, sea level rise, natural and anthropogenic disturbances, and competition from invasive species. Vegetation has been demonstrated to reduce wave energy, increase sedimentation, and decrease erosion in tidal environments under a range of...
Research indicates that child sex abuse contributes to emotional and behavioral
dysfunction in adult survivors. However, no one factor within the abuse experience has
been found to independently affect adult functioning, and it is unclear if several factors
acting together influence degree of dysfunction. This study compared the Global
Assessment...
Chum salmon (Oncorhynchus keta) were artificially
infected with erythrocytic necrosis virus (ENV) to study
the physiological and hematolgical consequences of ENV-infection.
Infected and control fish were held in
pathogen-free seawater and sampled weekly for five weeks.
Physiological tests included plasma cortisol, glucose,
protein, and osmolality, blood lactic acid, and liver...
The objective of this study was to investigate the effect of inorganic
and organic components of molasses on the laxative problem
encountered when molasses makes up a large portion of livestock
rations. In a series of four trials 280 male Long Evans rats weighing
approximately 50 grams each were placed...
The experimental procedure for reactively sputtering
films of silicon nitride together with the methods for
measuring the film thickness have been investigated.
Some of the properties of these nitride films were studied.
These properties included: infrared spectrum,
etching properties, and index of refraction. The adherence
of the films was also...
Vacuum evaporated dielectrics for use in MOS structures
were studied in this research project. Dielectric
films were deposited on substrates by electron bombardment
evaporation of sapphire and quartz source materials.
These deposited films were studied using infrared spectroscopy,
index of refraction, density, and dielectric constant
measurements. Etching tests were also...
In recent years, the new integrated circuit technology has spawned the
development of many low cost high performance microcontrollers. With the
improvement in the processor speed, instruction sets, and memory capacities,
these microcontrollers are ideal for the implementation of Control-Oriented
Local Area Networks (COLAN) for real-time distributed control systems. The...
The catchment-filter, soil erosion gage, macroprofile, and
spike and washer techniques for erosion measurement were compared
on six plots along a newly constructed logging road in the Oregon
Coast Range during the winter of 1965-66. Three plots were located
on a cut slope; three plots were on a fill slope....
Although some of the most difficult problems in forest management occur as a result of timber harvest operations, present methodology in harvest planning emphasizes guidelines which rely heavily upon the experience of the individual forest manager for their correct application. This study was undertaken in an effort to develop a...
A post-failure investigation of a highway embankment constructed
over organic and sensitive subsoils was made with a series
of field vane tests. The results indicated that the embankment was
quite stable, and, therefore, the reliabilities of both the Φ = 0 slip-circle analysis and the field vane results seemed to...
A sampling criterion which provides a numerical relationship
between sampling rate and worst-case peak error for linear interpolation
of sample points is presented. The criterion, based upon the
second derivative of a waveform, is derived, its properties are observed
for a sine wave, and its applicability to complex signals is...
A cooperative study sponsored by a grant from the Water Resources Research Institute Project No. A-001-ORE, Hydrology of Water Yield Prediction, and funding from the School of Forestry, both of Oregon State University.
This research is concerned with the current debate among Oregonians on how to improve the standard of living and accelerate economic development in Oregon. The main question is what economic activities make Oregon, and regions within Oregon grow? To find out where Oregon's economic strength and weaknesses lie, first we...
