A random utility model of trip demand for steelhead fishing is constructed by using a logit regression technique and data from the 1990 Oregon Angler Survey, conducted by the Oregon Department of Fish and Wildlife. The model is formulated to estimate demand when only the regional destination is known. Results...
The Timber Resource Inventory Model (TRIM) is a computer
model used by the U.S.D.A. Forest Service in assessing the
state of the Nation's forest resources and the forests'
probable future conditions. TRIM is a yield table
projection system designed and developed to model forest
inventory changes over time in response...
Since 1935, France has introduced a set of strict national wine rules and regulations, the Appellation d’Origine Contrôlée (AOC). The AOC limits fraud and oversees quality control by basing the rules on terroir. High quality from terroir comes has both physical and cultural factors. Before 1935, France produced a variety...
In order to assist WAC/WID practitioners and science writing faculty in incorporating translingual perspectives in disciplinary writing instruction, this study extends translingualism to language practice in the sciences by conducting a corpus study of Al-Awamia, a Moroccan agronomic journal. Mapping rhetorically significant changes across abstracts authored in English, French, and...
Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...
There is currently a revolution in archaeological morphometric research. As advances in technology are making more in-depth analyses both time and cost efficient. In this work, a collection of artifacts from the Pilcher Creek site (35UN147) in eastern Oregon was digitized using high resolution three-dimensional scanning. These scans were then...
In order to determine how contaminants from pharmaceutical, agriculture, and industry will move through groundwater systems, it is imperative to further our understanding of the relationship between physical, biological, and chemical properties of aquifers and transport and transformation of these products. Several studies have explored how heterogeneities in groundwater systems...
Monte Carlo (MC) algorithms are widely accepted as the most accurate method to calculate dose in a patient geometry. For this work the EGSnrc MC code was used as a benchmark for the identification of dose calculation errors produced by the widely implemented analytical anisotropic algorithm (AAA). By correlating the...
The focus of this research concentrates on enhancement
of the LOGSIM mechanized log harvesting system
simulator. Enhancement of software focuses on overall
improvement of the user environment as well as improvement
of the performance and capabilities of the simulation
package.
An enhanced version of the front-end interface
program is developed...
Part I. The total synthesis of (+)-leptosphaerin (2), a metabolite of the marine
Ascomycete Leptosphaeria Oraemaris (Linder) was achieved, unambiguously
establishing both the relative and absolute stereochemistry of this natural product. This
synthesis also resolved the long-standing question of which of the isomeric structures 1
or 2 correctly represents the...
