Investigation of Chain Extension Approaches for the Stereoselective Reagent-Controlled Synthesis of alpha-Heteroatom Substituted Alkyl Boronic Esters

Creator:: Barsamian, Adam L.
Abstract:: Two distinct strategies were explored for the enantioselective synthesis of α-heteroatom substituted alkyl boronic esters by stereoselective reagent-controlled homologation using transient chiral carbenoid reagents CHYMX (Y = heteroatom, X = nucleofuge, M = electrofuge). In the first case, a stereospecific reagent-controlled homologation (sStReCH) approach to α-alkoxyalkylboronates using α-metalated S,O- and...

Copper compounds for durable composites : effects on material properties

Creator:: Vidrine, Cheney L.
Abstract:: The effects of incorporation of selected biocides on physical and mechanical properties of aspen strandboard were assessed using five copper-based preservatives or zinc borate at three retention levels. Tebuconazole or 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (DCOI) were added as co-biocides to selective copper-based treatments. Mold box tests showed that only panels treated with DCOI...

A multiscale approach to bacterial adhesion

Creator:: Ostvar, Sassan
Abstract:: This work is an attempt to develop a simple physical description for the initial interactions between a bacterial cell and a substrate surface. This is done by adopting a view that regards bacterial surface biomolecules not as secondary and add-on contributors to the potential energy function that characterizes the overall...

Freeze-thaw cycles in permafrost soils and their impacts on the climate: A literature review

Creator:: Bergmann, Maya K.
Abstract:: Climate change is occurring at an increasingly rapid rate, with impacts heightened in the cold regions of the world including the Arctic. Warming effects are widespread, with one impacted process – freeze-thaw cycles – increasing in frequency and potentially triggering additional changes in permafrost soils that have previously acted as...

Relationship of Soil Type and Burn Severity to Post-Fire Vegetation Response

Creator:: Maclennan, Audrey
Abstract:: Public lands in the Pacific Northwest are managed for multiple uses including timber production, recreation and aesthetic value, maintaining wildlife habitat, conserving native species, and carbon storage. Wildfires impact large areas encompassing broad environmental conditions. Interactions among underlying environmental gradients and alteration of overstory competition by fire of varying severities...

Sensitivity analysis of the Catchment Modeling Framework (CMF) and use in evaluating two agricultural management scenarios

Creator:: Metta, John W. P.
Abstract:: Abstract Watershed-scale fate/transport modeling of contaminants is a tool that scientists and land managers can use to assess pesticide contamination to stream systems. The Catchment Modeling Framework (CMF) is a catchment-scale fate/transport modeling tool. It was developed to help scientists and land managers assess the effects of possible land-use decisions...

Sediment Deposition Characteristics in Shallow Saturation Excess Overland Flow with Application to Bioswales and Construction of a Novel Bioswale Design for Improved Contaminant Removal from Stormwater

Creator:: Wells, Jacqueline R.
Abstract:: Over the last two decades, urban stormwater management has grown to include green infrastructure, such as bioswales. These systems were primarily designed to mitigate hydraulic peaking during rainstorms but were also found to remove particulate and dissolved contaminants. However, little is known about the fate of these particulate contaminants after...

The Influence of Stormwater Water Quality on the Adsorption of Copper and Zinc onto Five Different Sorbents

Creator:: Kanalos, Casey A.
Abstract:: Best Management Practices (BMP) are widely used as a method for stormwater volume control in urban areas to prevent an overload of water on receiving water bodies and treatment facilities. BMPs ability to treat stormwater has gone under critical review in the last few decades, and their performance varies both...

Spatial and Temporal Variability of Heavy Metals (Lead, Copper, and Zinc) in Stormwater, Moss, and Street Dust in Portland, OR

Creator:: Bauer, Sophia O. A.
Abstract:: Lead (Pb), copper (Cu), and zinc (Zn) are known to have detrimental effects on aquatic and terrestrial ecosystems, and to human health both in rural and urban areas. Heavy metal contamination enters stormwater by atmospheric deposition and by the collection of surface particles during overland flow. Stormwater runoff in urban...

Addressing Persistent Challenges in Nanotoxicology Exposures : Techniques for in situ Characterization

Creator:: Crandon, Lauren E.
Abstract:: Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...
