Arising from an investigation in Hydrodynamics, the Korteweg-de Vries equation demonstrates existence of nonlinear waves that resume their profile after interaction. In this thesis, the classical equations governing wave motion are the starting point for the development of an analogue of the KdV that describes the evolution of a wave...
Concentrations of selenium (Se), manganese (Mn), zinc (Zn), cadmium (Cd), lead (Pb) and arsenic (As) were measured in the water column, sediment and biota, in conjunction with selected physicochemical data, from representative wetland types at a mining site within Salt Lake County, Utah, USA. The selected field sites included Oolitic...
The over-arching theme of this work is that soil data affect the performance and realism of vegetation models with particular focus on their ability to predict or explain disturbances such as fire or disease. We tested the sensitivity of the Excel version of the 3-PG model to soil properties and...
The abundance of algal species and their parasites
was monitored weekly for two years in a sewage lagoon
at the Corvallis Airport, Oregon. During the cooler
months, Euglena species were dominant followed by a
Chlamydomonas assemblage in the spring and a
predominantly Scenedesmus assemblage in the summer and
fall. Parasites...
As the demand for community mental health services grows, more and more counselors-in-training are being asked to face the challenge of working with high needs clients, including clients with Borderline Personality Disorder (BPD). Counselors-in-training are entering therapeutic relationships with high-risk clients without training specifically covering BPD client's unique needs. This...
The Environmental Conditioning System (ECS) was designed to evaluate the
water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...
The vast majority of terrestrial plant species live in symbiosis with arbuscular mycorrhizal fungi (AMF). AMF and plants live in complex networks, with roots of individual plants hosting multiple AMF, and single AMF colonizing multiple plants concurrently. Through the exchange of resources, the two partners of this symbiosis can have...
The testimonios of three Canadian women athletes and the 1980 Olympic boycott are presented. The Latin American method of testimonio is adapted as a framework for understanding personal stories. Testimonios written in a series of interpretive narratives and poems--poetic testimonios--represent three women's voices. This study includes three journeys: the research...
Zoos and aquariums are among the best informal education avenues for individuals to further develop conservation beliefs and values. Research documented the presence of conservation messages at aquariums, that visitors expect such messages, and staff and volunteers at conservation organizations increase their conservation-related knowledge and behaviors. This research often focuses...
A microchannel-based hemodialyzer offers a novel approach to hemodialysis practice and holds many promises for improving dialysis treatment efficiency and quality of life for kidney patients. The hollow fiber hemodialyzer, a conventional dialysis device, has certain limitations including non-uniformity of the dialysate flow path which necessitates the use of a...
