Treatment of dairy wastewater in a constructed wetland system : evapotranspiration, hydrology, hydraulics, treatment performance, and nitrogen cycling processes

Creator:: Niswander, Steven Francis
Abstract:: Five unique but related studies were conducted at the Oregon State University Dairy Wetland Treatment System (OSUDWTS), Corvallis, OR. The research site consisted of six parallel wetland cells, which were built in 1992 and began receiving concentrated dairy wastewater in the fall of 1993. Hydrologic, hydraulic, and water quality data...

Seasonal movement, home range, and abundance of the Mariana Common Moorhen (Gallinula chloropus guami) on Guam and the northern Mariana Islands

Creator:: Takano, Leilani L.
Abstract:: The endemic avifauna of Guam and the Mariana Islands represent a unique assemblage of bird species found nowhere else in the world and thus, are of considerable biological and conservation importance. Unfortunately, most of these species are understudied and exist in precariously low populations. The endangered Mariana Common Moorhen (Gallinula...

John Archibald Wheeler : a study of mentoring in modern physics

Creator:: Christensen, Terry M.
Abstract:: This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...

A containership load planning heuristic for a transtainer based container port

Creator:: Martin, Gifford L.
Abstract:: A heuristic is developed to plan loads for containerized cargo ships. It is designed to serve a port which uses gantry cranes (transtainers) and trucks to handle containers. The model recognizes constraints on ship stability, placing containers in a bay with the proper length, placing refrigerated cargo near electrical outlets,...

An economic analysis of small-holders agriculture in the central highlands of Ethiopia : a system simulation approach

Creator:: Bellete, Solomon
Abstract:: In the majority of the less developed countries the small-scale peasant agriculture is the dominant sector of the countries' economies. The successes of major agricultural programs in order to increase the potentials depend primarily on the understanding of the economic organizations of the peasant households. This study analyzed over a...

An analysis of trustee role perceptions in the state controlled Washington community college system and the locally controlled Oregon community college system and the relationship between trustee personal characteristics and these role perceptions

Creator:: Boyse, Peter Dent
Abstract:: This study examined the role perceptions of trustees in the locally controlled Oregon community college system and the state controlled Washington community college system. Authorities in the literature were consulted to define the "ideal trustee role" and the study determined which governance system was most effective in fostering this "ideal...

Natural products from tropical and temperate marine algae

Creator:: Bernart, Matthew W.
Abstract:: Following surveys of seaweeds in Oregon and the Caribbean, four algal species were selected for study on the basis of their crude extract biological activity or thin-layer chromatographic characteristics. Extracts were fractionated by normal phase chromatography, including high performance liquid chromatography (HPLC). Derivatives (methyl esters, acetates, and benzoates) of natural...

Ecology of mites on pomaceous fruit trees and related wild hosts in Hood River Valley

Creator:: Jorgensen, Clive Darrel
Abstract:: The ecological interrelationships of mites occurring in and near the Hood River Valley, Oregon, pome fruit orchards were investigated to determine the possibility of an integrated control program using the species already present. Survey sampling methods were used to study mites on wild hosts (Crataegus douglasii Lindl., Crataegus columbiana Howell,...
