In-situ Surface Modification of Wood with Different Hot Press Platen Metallurgies

Creator:: Freitas, Shawn Robert
Abstract:: As the forest industry moves toward the use of younger trees and production of an increasing number of composite products improving durability has gained importance. Coatings are one of the most widely used methods for improving wood durability because they improve resistance to water penetration, and subsequent shrinking and swelling,...

Non-Destructive Detection and Monitoring of Durability Issues in Wood Panels under Accelerated-Weathering

Creator:: Laleicke, Paul Frederik
Abstract:: Many wood composites are known to poorly resist the effects of moisture and temperature extremes over time. Degradation of adhesive bonds, irreversible thickness swell and dimensional instability result in a decrease of properties and a possible failure of the material. Accelerated weathering has become an essential tool for assessment of...

Developing a Methodology to Study the Effects of Adhesive Flow Penetration on Wood Adhesive Bond Performance by using Micro X-ray Computed Tomography (XCT) and Digital Volume Correlation (DVC)

Creator:: Ching, Daniel Jackson
Abstract:: Wood composites are an important renewable structural material which can be a net carbon sink when used in combination with sustainable forest management practices and high rates of log utilization. Adhesive bondlines are an essential part of composites, and for wood composites, they determine the moisture durability and mechanical performance...

Establishment and dynamics of methane-oxidizing microbial communities in marine sediments

Creator:: Klasek, Scott A.
Abstract:: Marine sediments are vast sources and reservoirs of methane, a potent greenhouse gas. Most of this methane is anaerobically oxidized by archaea before it can reach the overlying ocean, though the efficiency of this process often depends on methane fluxes and mechanisms of fluid transport. Anaerobic methanotrophic archaea, or ANME,...

Improving student satisfaction and retention with online instruction through systematic faculty peer review of courses

Creator:: Aman, Richard R.
Abstract:: The purpose of the study was to determine if online courses that were faculty peer reviewed based on five factors of quality instruction resulted in increased levels of student satisfaction and higher rates of student retention when compared with nonreviewed courses in a post-secondary context. The five factors of quality...

Institutionalizing sustainability in community colleges : the role of the college president

Creator:: Williams, Peter G.
Abstract:: The purpose of this research study was to describe and improve understanding of the meaning of institutionalized sustainability and the role that a college president plays in institutionalizing sustainability on a community college campus. The following questions guided the research: (a) What does it mean to have sustainability “institutionalized” at...

Ocean Acidification Impacts on Bivalves at Multiple Organizational Levels: From Individual Larvae to Bivalve Aggregations Habitats

Creator:: Gimenez Calvo, Iria
Abstract:: Many marine bivalves are sensitive to ocean acidification (OA) stress and often show heightened sensitivity during brief early larval and post-larval life stages, potentially leading to population bottlenecks. Most of the evidence to date has been collected in laboratory experiments that focused on physiological responses at the organismal level under...

Automated web-based analysis and visualization of spatiotemporal data

Creator:: Keon, Dylan B.
Abstract:: Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...

Examining parameters of vectorial capacity for mosquitoes associated with stormwater catch basins in Corvallis, Oregon

Creator:: Townzen, Jill S.
Abstract:: This research examines two of parameters of vectorial capacity for mosquitoes associated with catch basins in Corvallis, Oregon. The parameters of interest were determining 1) abundance of the mosquito species associated with the catch basins and 2) feeding patterns of local mosquito species. Three species of mosquitoes were collected from...

Landscape Genomics and Climatic Responses of Willamette Valley Alders

Creator:: Kral, George L.
Abstract:: The climate of the Pacific Northwest is in flux, and existing forest ecosystems are stressed and poised to shift in fundamental ways, with or without human intervention. This dissertation probes the nature of forest responses to environmental change through investigations of morphology and genetics of three species of alder co-occurring...
