The effects of pulsing and blowing ratio on a 45° inclined jet in cross flow

Creator:: Stander, Arjan
Abstract:: The effect of jet flow pulsing and blowing ratio on a jet in cross flow has been investigated. Preliminary jet flow studies were performed without cross flow and an extensive study of jet with cross flow was done for a total of nine test cases. The effect of velocities ratios...

Uncertainty, risk and forest management on the Tillamook State Forest : a case study

Creator:: Stander, Hendrik C.
Abstract:: Forest management is typically associated with a high degree of uncertainty, since it relies on predictions of natural growth processes over long periods of time. A number of methods exist for mitigating the risk associated with this uncertainty, but few have the ability to explicitly minimize risk. This study will...

Quantification of Copper Speciation in Pulp and Paper Wastewater and Implications for the Biotic Ligand Model

Creator:: Mitzel, Joseph M.
Abstract:: The purpose of this research was to measure the copper-binding behavior of Dissolved Organic Matter (DOM) contained in Pulp and Paper (P&P) wastewater effluent and evaluate the Biotic Ligand Model’s (BLM) ability to quantify copper speciation in P&P influenced waters. A copper ion selective electrode was used to measure copper...

Evaluation of copper removal from stormwater runoff using compost and Apatite II™

Creator:: Silvertooth, Jason R.
Abstract:: Low concentrations of dissolved copper have proven to be harmful to a number of aquatic organisms, with recent research highlighting detrimental effects to endangered salmonid species. Stormwater runoff can represent a significant source of copper to surface waters, necessitating cost-effective alternatives to current stormwater best management practices (BMPs). This study...

Copper Speciation in Wastewater-Impacted Surface Waters

Creator:: Mosbrucker, Ariel M.
Abstract:: This study investigates the relationship between total and ionic copper in samples taken from the Tualatin River and wastewater treatment facilities (WWTFs) that discharge into the Tualatin River. Copper speciation was analyzed by determining conditional stability constants and densities of copper binding ligands on the dissolved organic matter (DOM) in...

Heteroaggregation between citrate-stabilized gold nanoparticles and hematite colloids : mechanisms and quantification of nanoparticle-colloid interactions

Creator:: Smith, Brian M.
Abstract:: Understanding the aggregation behavior of engineered nanomaterials (ENMs) in aqueous environments is essential to understanding their fate, transport, and toxicity. Because naturally occurring colloids will likely be present at much higher concentrations than ENMs in environmental systems, heteroaggregation and attachment with these natural colloids could significantly influence ENM fate and...

Natural Organic Matter Surface Coverage as a Predictor of Heteroaggregation between Nanoparticles and Colloids

Creator:: Oney, Dylan M.
Abstract:: Heteroaggregation of nanoparticles with naturally occurring colloids has been shown to be an important process in nanoparticle fate and transport in the aquatic environment. The advent of a functional assay to measure heteroaggregation attachment efficiencies has opened the door for further mechanistic studies. It is well known that natural organic...

The assessment of copper and zinc removal from highway stormwater runoff using Apatite II™

Creator:: Huang, Hsiao-Wen
Abstract:: Copper and zinc are heavy metals commonly present in highway stormwater runoff. Discharge of these metals to surface waters inhabited by sensitive aquatic species including threatened and endangered salmonids has necessitated the need for improved treatment techniques. Although copper is of the greater toxicological concern, zinc is often present at...

Effects of biocide treatment on durability and fungal colonization of teak, western redcedar, and redwood

Creator:: Cabrera Orozco, Yohanna
Abstract:: Treating durable, second-growth or plantation-grown material with supplemental chemicals could improve durability while enhancing the uniformity of the products. To test this hypothesis, the effect of two candidate biocide treatments on the durability of teak, redwood, and western redcedar was assessed in a ground proximity field test established in Hawaii....

The effects of age and neuroticism on stress reactivity and cortisol diurnal rhythms : findings from the Normative Aging Study

Creator:: Proulx, Jeffrey A.
Abstract:: We examined the effect of daily stress, age, and emotional stability/neuroticism on stress reactivity, using cortisol diurnal rhythms. We used data from the Normative Aging Study (Spiro & Bosse, 2001). The 72 men in this study ranged from 67-93 (M =79.29, SD =4.88). Multilevel modeling showed that higher daily stress...
