Probabilistic Multi-hazard Earthquake-Tsunami Structural Risk Assessment Framework

Creator:: Alam, Mohammad Shafiqual
Abstract:: Catastrophic earthquake and tsunami events that resulted in significant loss of life and property over the past two decades have raised the global awareness regarding the need to understand the response of communities and their built environment to multi-hazard extreme events. In recognition to this impending threat to the coastal...

Post-dispersal seed fates in a Western Oregon native prairie

Creator:: Clark, Deborah L.
Abstract:: Knowledge of post-dispersal seed fates and other regeneration characteristics is crucial for predicting abundances and distributions of populations and, ultimately, community species composition and diversity. Seed fate studies, however, are rare primarily due to the difficulty of determining seed fates and causes of mortality. This thesis investigated post-dispersal seed fates...

Urea release from sulfur-coated urea and nitrogen utilization by tall fescue

Creator:: Pettygrove, G. Stuart
Abstract:: Sulfur-coated urea (SCU), a slow release nitrogen fertilizer, may be economically competitive with conventional fertilizers, but little is known of the mechanism of urea release from SCU and the environmental factors which affect the urea release rate. Objectives of this thesis were: (1) to determine factors which affect the rate...

An historical review of Kolb's formulation of experiential learning theory

Creator:: Hickcox, Leslie K. (Leslie Kay), 1951-
Abstract:: The central purposes of this study were to review the historical sources of David Kolb's formulation of experiential learning theory, and to determine the effect and application of Kolb's theory and Learning Style Inventory as reflected in the literature between 1971 and 1990. It was found that Kolb based his...

Biogeochemical signals of mountainous forested watersheds' response to disturbance

Creator:: Guerrero-Bolaño Francisco J.
Abstract:: Small mountainous watersheds are disproportionate sources of land-derived particulate organic matter (POM) to long-term sinks like lake bottoms and the ocean. As such, these ecosystems are an essential component of the global carbon cycle. The burial of POM in lacustrine and marine sediments contributes to the drawdown of atmospheric CO2...

The higher classification of the Hesperiidae (Lepidoptera: Hesperioidea)

Creator:: Warren, Andrew D.
Abstract:: A comprehensive tribal-level classification for the world's subfamilies of Hesperiidae, the skipper butterflies, is proposed for the first time. Phylogenetic relationships between tribes and subfamilies are inferred using DNA sequence data from three gene regions: 943 bp of cytochrome oxidase subunit I (COI) (in the mitochondrial genome), 739 bp of...

Evaluating Biochar for the Sustainable Treatment of Heavy Metals in Stormwater: Characteristics, Mechanisms, and Barriers

Creator:: Burch, Sarah
Abstract:: Heavy metals, such as copper, zinc, and cadmium, are ubiquitous in stormwater and potentially toxic to aquatic organisms at low concentrations. Removal of heavy metals contamination by conventional treatment is expensive and does not always reduce metals concentrations low enough to ensure safety of all aquatic species. This research seeks...
