Dichotemies Of The Human Perception Of The Environment, Janet K. Robson

Undergraduate Honors Capstone Projects

Environmentalism was not introduced in the year 1991, nor was it introduced with the era of the sixties. Perhaps, it is best to say that environmentalism has existed since the dawn of time--an environmentalism consisting of a "hands-off" policy. However, movements based on the environment have experienced an evolution in the past 30 years pertaining to the nature of preservation of wilderness areas and natural resources.

Mathematical Programming Applications In Agroforestry Planning, Laurence H. Reeves

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agroforestry as a sustainable production system has been recognized as a land use system with the potential to slow encroachment of agriculture onto forested lands in developing countries. However, the acceptance of nontraditional agroforestry systems has been hampered in some areas due to the risk-averse nature of rural agriculturalists. By explicitly recognizing risk in agroforestry planning, a wider acceptance of agroforestry is possible. This thesis consists of a collection of three papers that explore the potential of modern stock portfolio theory to reduce financial risk in agroforestry planning.

The first paper presents a theoretical framework that incorporates modern stock portfolio …

Cheap Auroral Tomographical System (Cats), Dean Garlick, Andrew Goldfinger

Small Satellite Conference

The Cheap Auroral Tomographical System (CATS) consists of a large constellation of small, disposable satellites in a near polar orbit. CATS is designed to collect stereoscopic views of the earth environment that will be used for tomographical and earth environmental research. Each satellite will be identical and constructed of high-grade commercial parts, thus significantly reducing the cost of design, fabrication and components. The CATS constellation will be a significant step toward the demonstration and validation of the capability to develop, deploy and operate a proliferated system of small, inexpensive satellites. Additionally, CATS will gather valuable scientific data from the earth …

In Wildness Is The Preservation Of The World, Michael Frome

Natural Resources and Environmental Issues

Passage of the Wilderness Act of 1964 and establishment of the National Wilderness Preservation System represent an historic achievement, an assertion of idealism in a materialist-powered society. The four federal land-management agencies, however, have failed to meet their legislative mandate. Thus Earth Day 1990 provides a singular opportunity to address the unfinished agenda with consideration of a new agency to be called the United States Wilderness Service.

Approach To Bioremediation Of Contaminated Surface Soils, J. L. Sims, Ronald C. Sims, J. E. Matthews

Biological Engineering Faculty Publications

Biological processes, including microbial degradation, have been identified as critical mechanisms for attenuating organic contaminants during transit through the vadose zone to the groundwater. On-site soil remedial measures using biological processes can reduce or eliminate groundwater contamination, thus reducing the need for extensive groundwater monitoring and treatment requirements. On-site remedial systems that utilize the soil as the treatment system accomplish treatment by using naturally occurring microorganisms to treat the contaminants. Treatment often may be enhanced by a variety of physical/chemical methods, such as fertilization, tilling, soil Ph adjustment, moisture control, etc. The development of a bioremediation program for a specific …

Microscopic Effects Of Predator Digestion On The Surfaces Of Bones And Teeth, John M. Rensberger, Hartmut B. Krentz

Scanning Microscopy

Concentrations of small fossil mammals are frequently encountered in Cenozoic deposits, but the causes for such accumulations have seldom been determined. In many cases the tooth, jaw, and limb fragments appear to be well-preserved under light microscopy, and it is difficult to differentiate damage due to predator digestion from breakage and abrasion due to physical agents. In order to find more specific evidence of predator digestion, we used a scanning electron microscope (SEM) to examine the surface microstructure of bones and teeth consumed by Bubo virginianus (great horned owl) and Canis latrans (coyote), which prey upon similar species. Effects …

Preparation Of Biological Samples For Transmission X-Ray Microanalysis: A Review Of Alternative Procedures To The Use Of Sectioned Material, D. C. Sigee

Scanning Microscopy

Although transmission X-ray microanalysis of biological material has traditionally been carried out mainly on sectioned preparations, a number of alternative procedures exist. These are considered under three major headings - whole cell preparations, analysis of cell homogenates and biological fluids, and applications of the technique to microsamples of purified biochemicals. These three aspects provide a continuous range of investigative level - from the cellular to the molecular.

The use of X-ray microanalysis with whole cell preparations is considered in reference to eukaryote (animal) cells and prokaryotes - where it has particular potential in environmental studies on bacteria. In the case …

The Interactive Effects Of Water Salinity And Management On Symbiotic Nitrogen Fixation In Alfalfa, Thomas J. Keck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A greenhouse study was conducted to assess the interactive effects of three irrigation water salinity levels (1.0, 3.0, and 9.0 mmho/cm) and three quantities of water app lied per irrigation (120, 240, 360 ml) on plant growth and nitrogen fixation by alfalfa (Medicago sativa L. cv. Resistador). Harvest dates corresponded to 10, 30, and 50 days after the initiation of salt and water treatments which were started after nodulation had been established in young plants.

Alfalfa top growth was limited by both salt and water stresses. Irrigation water salinity had a greater effect on top growth than root growth …

An Evaluation Of Deschampsia Caespitosa (L.) Beauv Populations For Metal Tolerances And Ecotypic Variation At Climax, Colorado, Paul Ellsworth Pratt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Four populations of Deschampsia caespitosa (L.) Beauv (a Poaceae species), growing on disturbed and undisturbed sites at Climax, Colorado, were examined for metal tolerances (Zn, Cu, Pb, Al). Root growth assessments on parent plant and offspring material for each population were conducted using nutrient solutions containing elevated levels of Zn, Cu, Pb, or Al. Seed germination and seedling survival tests for each population were conducted on both alpine topsoil and mine spoil material.

Evidence is presented that supports the hypothesis that ecotypic variation exists within Deschampsia caespitosa and that this variation has allowed certain Deschampsia populations to become successfully established …

Impacts Of Western Coal, Oil Shale, And Tar Sands Development On Aquatic Environmental Quality: A Technical Information Matrix; Volume 1 Introduction And Instructions, Jay J. Messer, Charles I. Liff, Kurt Gernerd, Frederick J. Post

Reports

Introduction: The Upper Colorado River Basin contains vast deposits of coal, oil shale, and tar sands, which could undergo extensive development should oil prices rise or an international situation restrict oil imports. Naturally, the prospect of development of these alternative fossil fuels resources has led to concern over how extraction and conversion activities will impact environmental quality. A thorough understanding of the nature and magnitude of the resulting envionemental impacts is a necessary prerequisite, if the costs and risks of such activites are to be weighed against the economic benefits. When we set out to evaluated these costs and risks, …

Public Land Grazing: Going, Going, Gone?, E. Bruce Godfrey

Economic Research Institute Study Papers

America's publicly owned rangelands have been and will continue to be a major focal point of interest of members of the society. Recently, these lands have also become of interest to user groups which differ from the major traditional use of these lands--domestic livestock. The NRDC suit which spawned the environmental impact statements being written by BLM per- sonnel, the Resources Planning Act, and the Organic Act have focused attention on these lands to a greater degree that has not existed for some time. Much of the interest in these lands has questioned the role and impact of livestock grazing …
