This study evaluates the Earth Resources Technology Satellite-
One (ERTS-1) multispectral scanner (MSS) as a means of predicting
lacustrine trophic state and the magnitude of selected trophic state
indicators.
Numerical classificatory methods are employed to ascertain the
trophic character of 100 lakes in Minnesota, Wisconsin, Michigan,
and New York using...
Differences in the chemical composition of calcified structures can be used to reveal natal origins, connectivity, metapopulation structure, and reconstruct the environmental history or movement patterns of many marine organisms. Sharks, skates, and rays (elasmobranchs) lack the calcified structures, known as otoliths, that are typically used for geochemical studies of...
The overall goals of this research were to identify the
major human factors problems in the mass transit driver
cockpit, to identify the operational activities, and vehicle
components that are most likely to produce accidents and
injuries and to investigate, through an in-depth study, the
most hazardous human factors problems....
We believe concreteness, direct manipulation and responsiveness in a visual programming language increase its usefulness. However, these characteristics present a challenge in generalizing programs for reuse, especially when concrete examples are used as one way of achieving concreteness. In this thesis, we present a technique to solve this problem by...
The Quartz Mountain Obsidian Quarry is located in the Southeast corner of the
Bend Fort Rock Ranger District in central Oregon, approximately forty-five miles
southeast of Bend, Oregon.
The research of the Quartz Mountain Obsidian Quarry began with a literature
search of other quarry sites in the area and the...
This dissertation describes studies of isoprenoid biosynthesis in the
phytoflagellate Euglena gracilis. Elucidation of a novel isoprerioid pathway, the 2-Cmethyl-D-erythritol-4-phosphate (MEP) pathway, in addition to the generally known
mevalonate (MVA) pathway, led to extensive exploration of the distribution of both pathways in a variety of organisms. To date, photosynthetic eukaryotes...
The major objective of this research was to develop a general descriptive and statistical base of information concerning agricultural cooperatives private motor vehicle operations in the Pacific Northwest states of Idaho, Montana, Oregon, and Washington. The specific objectives of the study were: (1) to determine the number, sizes, types, and...
PURPOSE Rural hospitals began to make significant changes in the 1990s by becoming integrated with larger health systems. The literature has correlated several key measures that determine the success of integrated health systems. These measures were quality, financial strength, community benefit, physician outcomes, and service changes. The purpose of this...
