Oregon's twenty-two smaller port districts have the means to
undertake a variety of community development goals. The activities of
these public bodies extend beyond facilitating maritime commerce and
harbor improvement. A primary responsibility, exemplified by a brief
look at the evolution and contemporary authority of ports in Oregon, is
to...
The life history of the Obscure Root Weevil, Sciopithes obscurus (Horn), on Rhododendron was studied at four sites in the Willamette Valley. This research was conducted in an effort to provide information necessary to develop adequate methods to control this Curculionid pest on Rhododendron in the Willamette Valley. Five larval...
Model testing has proven to be an effective tool in the study of
soil-structure systems. While primarily used in research work, this
method of evaluation is also applicable to the solution of many types
of complex design problems. Because of its workability and relatively
simple characteristics, sand is the most...
This research explores and aligns a postmodern method in line with a theoretical lens of "strategic political queer/feminism" to understand the construction and positioning of the issue/ problem of same-sex marriage. The method takes shape through a theoretical framework that leads to a political maneuver opening access to the rights...
This history concerns the scientific contributions of Charles
Babbage (1791-1871) to mathematics, to the invention of calculating
machines, and machine tools, to the development of scientific ideas
through a wide variety of scientific investigations and his involvement
in several different scientific reforms. Babbage considered himself
a philosopher in the broadest...
Uninhabited aerial vehicles, also called UAVs are currently controller by a combination of a human pilot at a remote location, and autopilot systems similar to those found on commercial aircraft. As UAVs transition from remote piloting to fully autonomous operation, control laws must be developed for the tasks to be...
The Washington State Department of Transportation (WSDOT) is the largest developer of wetlands land in the state of Washington. Consequently, they are also the largest wetland mitigation developer in the state. Through various federal legislation, state and county environmental policies, and legal court decisions, all negatively impacted wetlands must be...
Human settlement patterns are the ways in which people locate themselves over the terrain in their area of occupation. Settlement pattern prediction attempts to define and understand the factors in culture, technology, and environment that shape the spatial distribution of habitation sites for a given group of people. A systematic...
Combinations of cohesive and cohesionless soils are often encountered
when evaluating the engineering properties of soils. The
stress-volume characteristics of the mixed soil are found to vary according
to the proportion of each component. If the cohesive soil
composes more than a certain fraction of the material, the magnitude
of...
Moisture damage has long been recognized as one of the most
critical factors influencing the performance of asphalt concrete (AC)
pavements. This moistureinduced damage occurs from either the
physical separation of the asphalt film from the aggregate or the
softening of the asphalt binder within the AC mixture in the...
Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...
The area devoted to pear production in the United States (U.S.) is declining due to lack of precocity and high
cost of production. The U.S. pear industry currently lacks "modern" orchard systems characterized by compact
trees that produce early, high yields of large, high quality fruit. Tall, shaded canopies are...
As a preliminary step toward the establishment of a
70 mm. aerial photo timber inventory system capable of
generating accurate stand tables, stock tables, and gross
volume estimates, this project focuses on the development
of a system which (1) eliminates the need to measure tree
height on the photos through...
An attempt to determine the relationship between the computer,
the computer program exchange organization and today's practicing
civil engineer has just been completed. A questionnaire was used to
obtain information and opinions from 850 selected practicing civil
engineers. Based on those questionnaires reaching their addresses,
a return rate of 81.7...
Recent demographic studies have revealed a greater diversity in settlement patterns among Mexican immigrant families resulting in rapidly climbing populations of immigrants in new areas of the country, particularly in rural areas, while growth in established destinations has slowed. Host communities play an important role in families' acculturation processes and...
The purpose of this research project was to gain a deeper understanding of the
lived experience of faculty of color. More specifically, this project explores how
diversity-related workload expectations impact faculty of color who work in
predominantly white community colleges. Known by various descriptors, the term
used in this research...
Highway construction projects require temporary changes in roadway characteristics, such as the number of operational lanes, lane path, lane width, shoulder width, and posted speed limit. These modifications which are often temporary in nature have the potential to impact driving performance. Many research efforts have focused on developing standards to...
