While some theatre companies maintain their own in-house archives or have developed relationships with archival repositories, many still struggle to remain focused on the pressing challenges of finding funding, adequate rehearsal and office space, and just trying to get the next show open. In 2009, the American Theatre Archive Project...
The purpose of this thesis is the determination
of the load characteristics of the Steam-Hyciro-Electric Plant owned and operated by the Lebanon
Electric Power and Water Co. This corporation furnishes
electrical energy for power and lighting service
and also the water supply to the city of
Lebanon, Oregon.
Geomorphic change along the lower Clackamas River is occurring at
a millennial scale due to climate change; a decadal scale as a result River
Mill Dam operation; and at an annual scale since 1996 due to a meander
cutoff. Channel response to these three mechanisms is incision.
Holocene strath terraces,...
Surface geology, seismic data, petroleum exploratory well data, and water well data
have been used to analyze the structural and tectonic history of the southern Willamette
Valley. Tertiary strata beneath the southern Willamette Valley appear to have had an early
Cascade or Clarno volcanic source to the east by the...
With the increased recognition of moss as a secondary forest product has come an increased concern for the ecological ramifications of moss harvest. Three issues of primary concern are (1) characterizing the epiphyte communities impacted by harvest, (2) assessing the host preferences of these epiphytes, and (3) describing the availability...
Although terrestrial lichens and bryophytes are common in upland plant communities of the Blue
Mountains in northeast Oregon, research on cryptogam communities in this region is wanting. Studies have
shown that lichens and bryophytes can reduce soil erosion and increase soil fertility in other semiarid
habitats of North America. Understanding...
The Horsetail Creek Bridge (HCB), constructed in 1914, is located along the Historic Columbia River Highway in Oregon. The original cross beams from the HCB were substantially deficient in shear strength, particularly for the projected increase in traffic loads. One control beam and three beams with varying configurations of a...
Metro received grant funding from the U.S. Environmental Protection Agency in 1995 to gather digital, or computerized, geographic data for the Clackamas River watershed. This atlas was produced as one way to share the information collected with resource managers, policy makers, and people living in and interested in the Clackamas...

In 1978, a ten year project was begun to examine
the synecological effects of livestock grazing riparian
ecosystems. A multitude of biotic arid physical factors,
many which were unique to riparian ecosystems, interacted
to form a complex and diverse riparian ecosystem.
A total of 256 stands of vegetation representing 60...
Since 1979, over $114 million of natural gas has been produced at the Mist Gas Field, currently the only commercial gas field in the Pacific Northwest. In the Mist Gas Field, the sandstone-dominated Clark and Wilson member of the upper Eocene Cowlitz
Formation is the reservoir and the overlying upper...
Surface and subsurface mapping are combined to determine the structure and geologic history of the eastern
half of the Simi fault in the Simi Valley area. Upper Cretaceous rocks exposed south and east of the Simi Valley are overlain unconformably by the nonmarine Simi Conglomerate of Paleocene age. The Marine...
The Mitchell inlier in north-central Oregon contains the largest exposure of Cretaceous marine sedimentary rocks in this region. Nearly 9,000 ft of Albian-Cenamanian rocks are exposed along the flanks of the Mitchell anticline. The Cretaceous section rests unconformably overlain by Tertiary volcanic rocks. The Cretaceous rocks have previously been divided...
Wildlife epidemiological outcomes can depend strongly on the composition of an ecological community, particularly when multiple host species are affected by the same pathogen. However, the relationship between host species richness and disease risk can vary with community context and with the degree of spillover transmission that occurs among co-occurring...
This project developed techniques and methods to measure single molecule conductance. Break gap junctions, used to measure electrical properties of single molecules, were explored. A Hewlett Packard mechanical nano-press was determined to be insufficient for creating a stable gap in which to conduct experiments. To avoid electromigration and bond annihilation...
The Tobin Range of central Nevada lies in the Basin and Range extensional
province near the transition between more extended terrane (>50%) to the south and
east, and generally less extended terrane to the north and west. Geologic mapping,
40Ar/39Ar dating and whole-rock geochemical analysis were employed to establish the...
Surface and subsurface data indicate that Cretaceous strata
in the southern Ventura basin are part of the northward prograding
Chatsworth submarine fan. The fan extends westward as far as
Trancas Beach in the Santa Monica Mountains and wells in the
Oxnard Plain and on Oak Ridge. The eastern edge of...
The need to preserve Oregon's estuaries has been expressed
through the Land Conservation and Development Commission's Estuarine
Resources Goal 16. The first use of the mitigation guideline set forth

Airport runway extension will fill 32 acres (13...
Four cross sections are balanced and retrodeformed to 250±50 ka and
975±75 ka to yield crustal shortening amounts and rates for the western
Transverse Ranges of California. The cross sections compare the shortening
that occurs along a transfer zone in which displacement is transferred eastward
from a surface reverse fault...
n-Tree distance sampling (NTDS), also known as k-tree sampling and point-to-tree sampling, has been promoted as a practical method for forest inventory. This simulation study evaluated the performance of three NTDS estimators, as compared with fixed plot sampling and horizontal point sampling, for estimating density and basal area in headwater...
A replicated before–after-control-impact study was used to test effectiveness of Oregon’s (USA) riparian
protection measures at minimizing increases in summer stream temperature associated with timber harvest.
Sites were located on private and state forest land. Practices on private forests require riparian management
areas around fish-bearing streams; state forest’s prescriptions are...
Using a quasi-experimental design, 118 Latina girls, ages 13-18, viewed five color photographs of White women. Girls viewed either images of sexualized women or images of non-sexualized women. After viewing the images, girls were asked to complete the sentence stem, “I am…” 20 times. Thirty percent of girls spontaneously described...
A 5-year-old, male, domestic rabbit had severe swelling of the left rear leg. Radiographs demonstrated a proliferative, infiltrative lesion involving the stifle joint, femur, and soft tissues of the thigh. Osteomyelitis or neoplasia was suspected, and the leg was surgically amputated. Grossly, a multilobular mass comprised cyst-like structures containing yellow...
