The present status of plastics is one of constant change, but
this thesis attempts to focus attention on the state of the industry as of
1967. Beginning with a brief title definition and history of plastics,
the writer proceeds to a discussion on the structural characteristics
of plastics. Under this...
Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...
This research assessed the effect of western juniper (Junlperus
occldentalls) removal on understory plant production and cover and
ponderosa pine (Pinus ponderosa) growth and plant water status.
A complete randomized block design, with four blocks and four
treatments was established in the summer of 1984 near Prineville,
Oregon. The four...
On May 21, 1998 Kip Kinkel drove to Thurston High School in Springfield, Oregon. Kinkel killed two students and wounded another twenty-two students. He killed his parents the day before. The shootings at Thurston High School came on the heels of a number of prominent school shootings and Kip Kinkel...
The “fat-hunger paradox” is a relatively recent phenomenon in the United States in which people of low socioeconomic status are disproportionately overweight or obese, and yet frequently lack access to adequate food and nutrition. Research indicates additional disparities in the prevalence of overweight and obesity amongst most racial and ethnic...
A marine seismic refraction study, conducted in August 1976 by personnel
from Oregon State University and the University of Connecticut between Cape
Simpson and Prudhoe Bay, Alaska, provides data for analysis which yields a
subsurface structural and geological cross-section of the area.
The results suggest that the structural homocline which...
The social and economic impacts of climate change on the Oregon Coast may be reduced if coastal managers begin planning now to put in place adaptation measures. Oregon Sea Grant conducted a web-based survey of Oregon coastal professionals to target climate change adaptation outreach and engagement efforts toward this audience....
A novel design, material, and fabrication method are presented to fabricate a passive micro-ball valve. Microvalves are critical components in microflow control devices used to control the fluid flows in microchannels. These microflow control devices can be integrated with microsensors to form micro analysis systems. Glass/silicon-based fabrication is complicated and...
The proposed construction of a four lane road, the
Salem Parkway, was evaluated regarding the potential environmental
impacts its location would have upon biotic resources and water
quality. Due to existing commitment of the study area to urbanization
and agriculture, only limited environmental sensitivity was observed
overall. It was found...
Congress created the Collaborative Forest Landscape Restoration Program (CFLRP) in 2009 with the passage of the Forest Landscape Restoration Act (Omnibus Public Lands Management Act of 2009 Title IV). The purpose of the CFLRP legislation is to implement forest restoration work on national forest lands through a competitive grant program....
