Exploration of Simultaneous Anammox and Denitrification (SAD) Biofilm Processes for Nitrogen Removal

Creator:: Hilliard, Richard F.
Abstract:: Anammox (anaerobic ammonium oxidation) bacteria are capable of providing low-cost nitrogen removal for numerous types of wastewaters. However, low growth rates cause long startup-times and inhibition by oxygen and metabolic substrates necessitate close process control to maintain performance. Incorporation of Simultaneous Anammox and Denitrification (SAD) into constructed wetlands could provide...

Seed bank response to juniper expansion in the semi-arid lands of Oregon, USA

Creator:: Duncan, Corinne M.
Abstract:: Expansion of Juniperus occidentalis into the sagebrush steppe has resulted in significant changes in understory composition. A consequence of increased J. occidentalis dominance may be a depletion of the seed bank. The potential for depletion is problematic because a reduction in the amount of species available from the seed bank...

Hydrophobicity, Anion Exchange, and Phytoaccumulation of Per- and Polyfluoroalkyl Substances (PFAS): Retention and Remediation

Creator:: Parker, Bethany A.
Abstract:: Per- and polyfluoroalkyl substances (PFAS) are a group of contaminants of great concern due to their toxicity and ubiquity in the environment. Remediation efforts historically have focused on granular activated carbon (GAC) because of its low maintenance and relatively low cost. However, GAC is not PFAS selective and is especially...

Developing self-efficacy and self-regulated learning in academic planning : applying social cognitive theory in academic advising to assess student learning outcomes

Creator:: Erlich, Richard J.
Abstract:: This dissertation demonstrates how Social Cognitive Theory (Bandura, 1986, 1997) can be successfully applied to Counselor academic advising interventions, in order to increase students' self-efficacy and self-regulated learning (Zimmerman, 2000) in academic planning as learned outcomes. This was accomplished by (a) reviewing the academic advising literature and showing the current...

A motor-generator and supercapacitor based system for microgrid frequency stabilization

Creator:: Crispo, Richard F.
Abstract:: This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term...

Understory vegetation response and nitrogen cycling following cutting of western juniper

Creator:: Bates, Jonathan D.
Abstract:: Since the late 1880's western juniper has expanded in range and increased in density in sagebrush-bunchgrass, riparian, and forested plant communities of the Pacific Northwest. Succession to western juniper woodland has been shown to reduce the productivity and diversity of the understory component, result in concentration of soil nutrients beneath...

Getting Kids from Cradle to College: Parents’ Expectations and Support to College-Bound Children

Creator:: Ottusch, Timothy M.
Abstract:: Increasing numbers of individuals aspire to, seek out, and need a college degree in order to be competitive in the job market (Goyette, 2008; U.S. Department of Education, 2013). College degrees provide access to economic, social, and health benefits (Abel & Deitz, 2014; Autor, 2014). The United States also needs...

Compositional variations in hydrothermal white mica and chlorite from wall-rock alteration at the Ann-Mason porphyry copper deposit, Nevada

Creator:: Cohen, Julia F.
Abstract:: The detection of subtle variations in mineral chemistry in zoned hydrothermal alteration associated with the formation of porphyry copper deposits by short-wave infrared spectroscopy and rock chemistry are potentially valuable vectoring tools for mineral exploration. In order to correctly interpret the data collected by these methods, results must be calibrated...
