Abstract:: Nitrosomonas sp. Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family Nitrosomonadaceae within the phylum Proteobacteria. Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Nitrosomonas sp. Is79 is an ammonia oxidizer of high...

Water quality modeling of the Tualatin River

Creator:: Berger, Christopher J. (Christopher John)
Abstract:: Water quality problems related to excessive algal growth, high nutrient loading, and low flows have been occurring along Oregon's Tualatin River. The Tualatin River is 86 miles long and has a drainage basin of 711 square miles. The drainage basin incorporates forest, agricultural, and urban areas. Located in the Portland...

Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

Creator:: Sharp, Christopher J.
Abstract:: Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...

Grounded Theories Describing How White Mental Health Counselors Develop Nonracist White Racial Identities

Creator:: Cleaver, Christopher J.
Abstract:: The purpose of this dissertation was to extend the current body of knowledge regarding the experiences and processes involved regarding how White mental health counselors deconstruct their internalized, and often unacknowledged, racism as well as attempt to dismantle institutionalized racism, in order to develop nonracist White racial identities. By adding...

A CFD Analysis of a Single Channel in the Mars Hopper Engine

Creator:: Koll, Christopher J.
Abstract:: The Mars Hopper is an alternative extraterrestrial vehicle for the collection of samples from the Martian surface. This thesis studied the engine of the Mars Hopper to assess the validity of the current planned launch cycle according to current parameters. To do this, the engine was simplified to an average...

Carbon isotopes show snowpack acts as a valuable moisture subsidy to mountain forests in the Oregon Cascades

Creator:: Ratcliff, Christopher J.
Abstract:: This study examines climatological influences, particularly that of snowpack, on tree growth and stable carbon isotope discrimination (Δ¹³C) from ~1980 to 2013 at two sites located in the upper reaches of the McKenzie River watershed of the Oregon Cascade Mountains. We tested the use of Δ¹³C values from latewood, corroborated...

Wave Energy Converter Array Optimization : Array Economic Analysis and Preliminary Results of a Genetic Algorithm Approach Introducing Cost Factors

Creator:: Sharp, Christopher J.
Abstract:: With the need to integrate renewable energy sources into the current energy portfolio and the proximity of many population centers to an ocean coastline, it is pressing that marine energy systems, specifically wave energy converters (WECs), are evaluated as potential solutions for meeting energy needs. In order to best understand...

Mixed-Severity Fire Effects on Biological Legacies and Vegetation Response in Pseudotsuga Forests of Western Oregon's Central Cascades, USA

Creator:: Dunn, Christopher J.
Abstract:: Mixed-severity fire occurrence is increasingly recognized in Pseudotsuga forests of the Pacific Northwest, but questions remain about how tree mortality varies, and forest structure is altered, across the disturbance gradient observed in these fires. Therefore, we sampled live and dead biological legacies at 45 one ha plots, with four 0.10...

Defining drug court participant community college success

Creator:: Hamilton, Christopher J.
Abstract:: Drug courts are collaborative community programs that provide active oversight and compliance monitoring of individuals engaged in the criminal justice continuum. Adult drug court program requirements include alcohol and other drug treatment, community support services, and other ancillary services intended to promote life changes in participants and ultimately, prosocial behaviors....
