Buffer strips have been proposed as a method for controlling temperature changes in streams adjacent to clear-cuttings. Nine small mountain streams in Oregon's Coast Range and Cascade Mountains were studied to determine the influence of buffer strips on water temperature. Timber volume in the strip, strip width, and canopy density...
Six headwalls in the central Oregon coast range were selected for study of soil engineering properties and vegetativecharacteristics important for analysis of slope stability. The headwalls were considered representative of those which would be candidates for timber leave areas due to geomorphic and topographic features, including steepness of slope and...
The Chelan Valley is one of several valleys located on the eastern slope of the Cascade Mountains contributing to the leadership of Washington in apple production. Since the nature of the activity in the Chelan Valley is typical of all these producing areas,it was selected as a case study of...
American women’s quest for equality came into focus in the early 1900s. Amidst the cultural and societal forces pushing for suffrage, some chose the mechanism of theater. This thesis is a work of rhetorical criticism. It applies Lloyd Bitzer’s situational approach to two suffrage theater artifacts: Mary Shaw's The Woman...
The purpose of the study was to assess county extension agents'
knowledge of geotextiles; to determine their current level of
information and their location on an adoption-diffusion curve; and to
determine the agents' attitudes toward the potential use of
geotextiles in agriculture, specifically in soil erosion control.
A questionnaire was...
The middle to upper Eocene Tillamook Volcanics form the basement in the Rock Creek - Rocky Point area. These tholeiitic to alkalic basalts, basaltic andesites, and andesites were erupted as shield volcanoes seaward of the strandline ontop of an older deep-marine mudstone unit (Yamhill Formation) and an accreted portion of...
The metastable isotope of technetium-99 (Tc-99m) is an important diagnostic tool used in the field of nuclear medicine due to the isotope's 6.0 hour half-life, 140.5 keV γ-decay mechanism, and multiple oxidation states [1,2]. Approximately 70% of the world’s nuclear medicine procedures involve the use of Tc-99m [3]. The conventional...
The Mixteco primarily reside in the Mexican State of Oaxaca in Southwestern Mexico. They have been arriving in larger numbers then ever before to this part of the North American continent in the last twenty years.Their experience is composed of different dynamics compared to those of their mainstream Mexican counterpart....
Tolerance analysis and synthesis plays a vital role in the success of a product design because it directly affects product quality and manufacturing cost. It also affects manufacturing process selection and planning. This research provides a review of several commonly used assembly tolerance analysis models and evaluation of their limitations....
The settlement history of a remote area in the Coast Range of Oregon, from the 1870s to the 1930s, is examined through factors that may have influenced the success or failure, and length of residence of the homesteaders and later residents. Despite the rugged and isolated location, a small community...
