Selenium Poisoning Of Wildlife And Western Agriculture: Cause And Effect, N. E. Korte

All U.S. Government Documents (Utah Regional Depository)

This project examined the hypothesis that selenium contamination is not the principal cause of the decline of endemic fish species in the Upper Colorado Basin. Activities employed to test this hypothesis included a reconnaissance of locations altered by recent road construction, a reinterpretation of available literature regarding selenium toxicity, and the interpretation of unpublished data obtained from the Upper Colorado Basin Fish Recovery Program. The project demonstrates that most of the evidence implicating selenium is circumstantial. Specifically, this research demonstrates that neither the historical record nor the technical literature consistently supports the emphasis given selenium toxicity. For example, many locations …

Institute for Sustainable Solutions Publications and Presentations

No set of issues has tended to separate economists and ecologists, especially in the mind of the public, more than those surrounding the linkages between economic growth, human carrying capacity, and the environment. The general lack of interest among the majority of economists in problems of the environment and a parallel lack of interest among the majority of ecologists in economic issues, combined with a lack of dialogue between the two groups, has allowed extreme positions to take hold in the public debate and to influence policy to an inordinate degree.

Degradation Of N-Hexadecane And Its Metabolites By Pseudomonas Aeruginosa Under Microaerobic And Anaerobic Denitrifying Conditions, Chawala Chayabutra, Lu-Kwang Ju

Chemical, Biomolecular, and Corrosion Engineering Faculty Research

A strategy for sequential hydrocarbon bioremediation is proposed. The initial O-2-requiring transformation is effected by aerobic resting cells, thus avoiding a high oxygen demand. The oxygenated metabolites can then be degraded even under anaerobic conditions when supplemented with a highly water-soluble alternative electron acceptor, such as nitrate. To develop the new strategy, some phenomena were studied by examining Pseudomonas aeruginosa fermentation. The effects of dissolved oxygen (DO) concentration on n-hexadecane biodegradation were investigated first. Under microaerobic conditions, the denitrification rate decreased as the DO concentration decreased, implying that the O-2-requiring reactions were rate limiting. The effects of different nitrate and …

Stocking Rate Guidelines For Rural Small Holdings, Swan Coastal Plain And Darling Scarp And Surrounds, Western Australia, Dennis Van Gool, Ken Angell, Lindsay Stephens

Agriculture reports

Small rural holdings are often owned by people who want to pursue a semi-rural lifestyle but who are inexperienced in land management issues. This can result in landholders stocking their properties with animals at rates higher than the land resources can sustain, leading to degradation problems such as soil erosion, water pollution and damage to vegetation. This document provides information and guidelines to help planners, developers, local authorities and land owners determine the base stocking rates for rural small holdings on the Swan Coastal Plain and Darling Scarp and immediate surrounds. The advice utilises Agriculture Western Australia’s rural stocking rate …

Levels Of Synthetic Musks In Municipal Wastewater For Estimating Biota Exposure In Receiving Waters, Lantis Osemwengie

UNLV Theses, Dissertations, Professional Papers, and Capstones

Natural musk (muscone) is a highly prized natural product for use in expensive consumer fragrances. Inexpensive synthetic substitutes have been commercialized over the last 40 years. Two main chemical classes are used commercially — the nitro musks (which fulfilled the original demand for inexpensive fragrance additives for personal care products such as bath soap, body lotions, perfumes, and washing detergents) and the newer polycyclic musks which have musklike smell. The commercial nitro musks include musk ketone, musk moskene, musk ambrette, musk xylene, and musk tibetene. The polycyclics include trade named compounds such as Galaxolide®, Tonalide®, Celestolide®, Traseolide®, Phantolide®, and Cashmeran®, …

To Who Or What Do We Owe Sustainable Development? A Search For An Ethical Framework For Sustainable Development, Mia Soderlund

Theses

This thesis focuses on the ethical dimension of sustainable development as described in the Bruntland report. According to this report, we do have certain moral obligations to future generations. This thesis asks whether traditional moral philosophy, such as utilitarian and contractarian theories, can justify moral obligations to future generations, and if they can serve as ethical frameworks for sustainable development.

The basic idea with sustainable development is to create a balance between society, the environment and the economy. If the environment is ascribed instrumental value, which is the case with traditional moral philosophy then there is no balance, because its …

A Study Of Platinum, Palladium, Bismuth, Copper, And Silver For The Potentiometric Determination Of Chlorine, Maria A. Gottwald

Integration Of Multi Lifecycle Assessment And Design For Environment Database Using Relational Moddel Concepts, Bhagyashree Suratran

Theses

Multi-lifecycle Assessment (MLCA) systematically considers and quantifies the consumption of resources and the environmental impact associated with a product or process. Design challenges posed by a multi-lifecycle strategy are significantly more complex than traditional product design. The designer must look forward in time to maximize the product's end-of-life yield of assemblies, parts and materials while looking backward to the world of existing products for feedstock sources for the current design. As MLCA and DEE share some common data items, such as, part geometry, material and manufacturing process, it is advantageous to integrate the database for MLCA and DEE. The integration …

Standardizing The Evaluation Of Brown Tree Snake Trap Designs, Richard M. Engeman, Daniel S. Vice

United States Department of Agriculture Wildlife Services: Staff Publications

The introduced brown tree snake has had devastating impacts on the native vertebrate fauna of Guam. Trapping is the primary means by which brown tree snakes are removed, either in support of reintroduction of endangered species or to deter their movement from Guam in cargo. Traps used to control brown tree snake populations have been continually evolving since the 1980s. Before general operational implementation of a new design, the efficacy of new trap developments must be demonstrated. In this paper we combine the current knowledge about brown tree snake control objectives and practicalities, the information gained from a variety of …

P-Selectin Or Intercellular Adhesion Molecule (Icam)-1 Deficiency Substantially Protects Against Atherosclerosis In Apolipoprotein E-Deficient Mice, Robert G. Collins, Rizwan Velji, Natalia V. Guevara, M. John Hicks, Lawrence Chan, Arthur L. Beaudet

Physics & Astronomy Faculty Publications

The expression of leukocyte and endothelial cell adhesion molecules (CAMs) is essential for the emigration of leukocytes during an inflammatory response. The importance of the inflammatory response in the development of atherosclerosis is indicated by the increased expression of adhesion molecules, proinflammatory cytokines, and growth factors in lesions and lesion-prone areas and by protection in mice deficient in various aspects of the inflammatory response. We have quantitated the effect of deficiency for intercellular adhesion molecule (ICAM)-1, P-selectin, or E-selectin on atherosclerotic lesion formation at 20 wk of age in apolipoprotein (apo) E(- /-) (deficient) mice fed a normal chow diet. …

Brown Tree Snake Discoveries During Detector Dog Inspections Following Supertyphoon Paka, Daniel S. Vice, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Detector dog inspection of outbound cargo is one of several control methods applied to deter brown tree snake dispersal from Guam. In the two and a half months following the passage of Supertyphoon Paka over Guam, an increase in brown tree snake discoveries during detector dog inspections was observed. We report here on the circumstances of those discoveries and their management implications.

Extensive Forest Leaf Area Survey Aiming At Detection Of Vegetation Change In Subarctic-Boreal Zone, Tomoko Kusakabe, Hayato Tsuzuki, Gary B. Hughes, Tatsuo Sweda

Statistics

The warming resulting from increasing anthropogenic carbon dioxide and other greenhouse gasses is expected to be most prominent in the subarctic-boreal region of the Northern Hemisphere. With the objective of setting up a baseline to monitor possible vegetation change in this region, a continuous vegetation profile extending 600 km from Edmonton, Alberta to Cluff Lake, Saskatchewan, Canada was measured using an airborne infrared laser altimeter mounted on a helicopter. Then the distribution of leaf area index over the same 600 km long transect was estimated from this vegetation profile based on a series of plot surveys on the ground to …

Breeding Season Demography And Movements Of Eastern Towhees At The Savannah River Site, South Carolina, David G. Krementz, Larkin A. Powell

School of Natural Resources: Faculty Publications

The Eastern Towhee (Pipilo erythrophthalmus) has undergone population declines across much of its range, especially in New England. Despite being a widespread and, at one time, a common species, relatively little is known about its natural history, ecology, or demographics. We conducted baseline research on Eastern Towhees at the Savannah River Site, South Carolina, in 1995 and 1996 to estimate breeding season survival rates, nest success rates, breeding densities, and daily movements. We also were interested in whether towhees had differences in survival and movement rates between young and mature managed pine stands. We found that survival rates during the …

The Effects Of A Functional Derotational Knee Brace On The Single-Leg Hop, Timed-Hop, And Stability Of Ncaa Division Ii Athletes, Heidi E. Moran

Theses, Dissertations and Capstones

Functional knee braces are often used by athletes following an injury to their anterior cruciate ligament (ACL). However, few athletes are given information as to whether the knee brace will hinder their ability. The purpose of this study was to examine the effects of a functional derotational knee brace on the single leg hop for distance, timed hop, and overall stability index of athletes. Twelve healthy knees were tested with and with out an off-the-shelf DonJoy Legend knee brace. A matched T-test showed a significant difference between the single leg hop (T = 2.71, p<.05) and timed hop (T=3.23, p<.05) while wearing the knee brace. There was no significance found when examining the stability index while wearing the brace. It was concluded that the functional knee brace decreased the distance of a single leg hop and increased the time it took to perform a timed hop.

Outdoor Adventure And Health: Supporting Empirical Data, Camille J. Bunting

Research in Outdoor Education

The intent of this paper is to introduce a theoretical framework for considering connec­tions between outdoor adventure and health, not to present the findings of one or two new re­search studies. A compilation of empirical data will be presented from various studies to illus­trate the proposed connections, and provide documentation for subjective observations and beliefs long held by outdoor adventure educa­tors. Therefore, the format that follows is not one of a typical research report, but of a position paper with supporting empirical data from the author's own research.

The Effect Of Landfills On Rural Residential Property Values: Some Empirical Evidence., Rachel Bouvier, John M. Halstead, Karen S. Conway, Alberto B. Manalo

Natural Resources & the Environment

Abstract

The question of whether solid waste landfills affect residential property values has long been a subject of debate. Past research has resulted in mixed conclusions. The current study examines six landfills, which differ in size, operating status, and history of contamination. The effect of each landfill is estimated by the use of multiple regression. In five of the landfills, no statistically significant evidence of an effect was found. In the remaining case, evidence of an effect was found, indicating that houses in close proximity to this landfill suffered an average loss of about six percent in value.
