Caution! High Water: A Historical Archaeological Investigation of the Champoeg Townsite (ORMA26) after the 1861 Flood

Creator:: Hill, Cayla L.
Abstract:: The Champoeg townsite first developed due to its ideal settlement and trade location within the Willamette Valley, becoming the ‘legal birthplace of Oregon’ in 1843. However, by 1860 Champoeg’s significance had begun to decline, and in December of 1861 a devastating flood wiped out the townsite. Archaeological excavations took place...

Approaches to the total synthesis of verrucarol

Creator:: Hill, David E. (David Edwin) 1954-
Abstract:: Verrucarol is the sesquiterpene portion of a number of macrocyclic di- and triesters of potential medicinal importance. In this study, a novel approach to the synthesis of this fungal metabolite is presented. An A-B-C route was investigated in which C-3 and C-4 of the C-ring were emplaced using a [2+2]...

A beta dosimeter and spectrometer utilizing plastic scintillators and a large-area avalanche photodiode

Creator:: Kriss, Aaron A.
Abstract:: The purpose of this research was to develop and test a radiation detector to perform beta dosimetry and spectroscopy. The detector utilizes plastic scintillator volumes to produce scintillation light in proportion to the amount of energy deposited in them, and a large-area avalanche photodiode to convert the light to electrical...

Simultaneous beta/gamma digital spectroscopy

Creator:: Farsoni, Abdollah T.
Abstract:: A state-of-the-art radiation detection system for simultaneous spectroscopy of beta-particles and gamma-rays has been developed. The system utilizes a triplelayer phoswich detector and a customized Digital Pulse Processor (DPP) built in our laboratory. The DPP board was designed to digitally capture the analog signal pulses and, following several digital preprocessing...

Simulation of cattle cycle demography: cohort analysis of recruitment and culling decisions in the national beef cow herd

Creator:: Nordblom, Thomas L.
Abstract:: This study expresses the hypothesis that historical patterns of national beef cow herd accumulation and liquidations (the cattle cycle) have been related to investment incentive differences across cow ages through time, resulting each year in changes in herd age structure, performance and potentials for adjustment in subsequent years. A review...

Early detection of weed resistance : pattern-thinking and rapid microcalorimetric assay

Creator:: Suwanagul, Duangporn
Abstract:: Weed resistance is usually diagnosed after a weed control practice has lost efficacy and weed populations begin to increase rapidly. Prediction and validation in the field at a very early stage of resistance development is a promising method for preventing an uncontrollable problem. Pattern-thinking helped individuals connect their experience of...

Regional Scale Modeling of Climate, Cryosphere, and Freshwater Discharge in Changing Coastal Mountain Environments

Creator:: Beamer, Jordan P.
Abstract:: The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...

Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

Creator:: Parker, Kai A.
Abstract:: Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...

Beta-particle backscatter factors and energy-absorption scaling factors for use with dose-point kernels

Creator:: Mangini, Colby D.
Abstract:: 'Hot particle' skin dosimetry calculations are commonly performed using homogeneous dose-point kernels (DPK) in conjunction with scaling and backscatter models to account for non-homogeneous geometries. A new scaling model for determining the actual DPK for beta-particles transmitted by a high-Z source material has been developed. The model is based on...
