Long-Term Recovery Of South Indian Creek Following Interstate Construction, Clara Mcclure Dec 2013

Long-Term Recovery Of South Indian Creek Following Interstate Construction, Clara Mcclure

Electronic Theses and Dissertations

The expansion of Interstate 26 from Erwin, TN to the North Carolina border was a project that potentially adversely impacted South Indian Creek because of the steep landscapes and potential for erosion. Several studies have shown the short-term, negative effects of road construction on the water quality of nearby water bodies. Non-point source pollution is the major source of water pollution in the United States. The primary objective of this research is to evaluate the long-term effects of the construction of Interstate 26 on South Indian Creek to see if there has been any ecological recovery. The Environmental Health Sciences …


Evaluation Of Arsenic And Selenium Quantitation In Marcellus Shales And Flowback Saline Waters Using Thiol Cotton Fibre-Graphite Furnace Atomic Absorption Spectroscopy And Diffusive Gradient In Thin Film Techniques, Ronald S. Balaba Dec 2013

Evaluation Of Arsenic And Selenium Quantitation In Marcellus Shales And Flowback Saline Waters Using Thiol Cotton Fibre-Graphite Furnace Atomic Absorption Spectroscopy And Diffusive Gradient In Thin Film Techniques, Ronald S. Balaba

Graduate Theses, Dissertations, and Problem Reports (ETD)

Trace levels of arsenic and selenium can be toxic to living organisms yet their quantitation in high ionic strength or high salinity aqueous media is difficult due to the matrix interferences which can either suppress or enhance the analyte signal. The objective of this proposed study has been to apply and/or modify inexpensive, simple, and interference-free analytical methods for the sub-ppb to ppb quantification of both inorganic and bioavailable arsenic and selenium fractions in highly saline/salty waters such as flowback wastewater produced from natural gas well drilling sites in the Marcellus shale and/or simulated or artificial high-salinity prepared from deionized …


An Experimental And Computational Evaluation Of The Importance Of Molecular Diffusion In Gas Gravity Currents, Jeremy Jac Herman Dec 2013

An Experimental And Computational Evaluation Of The Importance Of Molecular Diffusion In Gas Gravity Currents, Jeremy Jac Herman

Graduate Theses and Dissertations

The accidental release of hazardous, denser-than-air gases during their transport or manufacture is a vital area of study for process safety researchers. This project examines the importance of molecular diffusion on the developing concentration field of a gas gravity current released into a calm environment. Questions which arose from the unexpectedly severe explosion in 2005 at Buncefield, England were of particular interest. The accidental overfilling of a large tank with gasoline on a completely calm morning led to a massive open air explosion. Forensic evidence showed that at the time of ignition, a vapor cloud, most of which now appears …


Importance Of Placement Depth In Evaluating Soil Nitrogen, Phosphorus, And Sulfur Using Ion Exchange Resin Capsules In Semi-Arid, Low Fertility Soils, Rachel Lynn Buck Dec 2013

Importance Of Placement Depth In Evaluating Soil Nitrogen, Phosphorus, And Sulfur Using Ion Exchange Resin Capsules In Semi-Arid, Low Fertility Soils, Rachel Lynn Buck

Theses and Dissertations

Ion exchange resin capsules provide a possible alternative to conventional soil testing procedures. Previous studies with semi-arid, low fertility soils observed poor relationships with poorly mobile nutrients such as phosphorus (P). We propose that placement depth may improve those relationships. Our objective was to (1) determine if placement depth could improve resin capsule estimation of the bioavailability of nitrogen (N), P, and sulfur (S) and (2) to determine if resin capsules can effectively estimate S availability in semi-arid, low fertility soils. Field sites were established in Rush and Skull Valleys, Utah on loam and sandy loam soils, respectively. Fertilizer was …


Tracking The Cellulolytic Activity Of Clostridium Thermocellum Biofilms, Alexandru Dumitrache, Gideon M. Wolfaardt, David Allen, Steven N. Liss, Lee R. Lynd Nov 2013

Tracking The Cellulolytic Activity Of Clostridium Thermocellum Biofilms, Alexandru Dumitrache, Gideon M. Wolfaardt, David Allen, Steven N. Liss, Lee R. Lynd

Dartmouth Scholarship

Microbial cellulose conversion by Clostridium thermocellum 27405 occurs predominantly through the activity of substrate-adherent bacteria organized in thin, primarily single cell-layered biofilms. The importance of cellulosic surface exposure to microbial hydrolysis has received little attention despite its implied impact on conversion kinetics.

The Dam Truths Of Glen Canyon, Jeffrey D. Bennion, Dr. M. Brett Borup Nov 2013

The Dam Truths Of Glen Canyon, Jeffrey D. Bennion, Dr. M. Brett Borup

Journal of Undergraduate Research

The Glen Canyon Dam was completed by the Bureau of Reclamation in 1963 as the main feature of the Colorado River Storage Project. The purposes of the dam were to regulate the flow of the Colorado River, store water for consumptive use, provide for the reclamation of arid and semi-arid land, control floods, and generate hydroelectric power (U.S. Department of the Interior, 1995). Since the dam was completed prior to enactment of the National Environmental Act, no environmental impact statement was filed regarding its construction and operation. Many environmentalist groups, most recently the Sierra Club, have lobbied for the removal …

Gathering "Wild" Food In The City: Rethinking The Role Of Foraging In Urban Ecosystem Planning And Management, Rebecca J. Mclain, Patrick T. Hurley, Marla R. Emery, Melissa R. Poe Nov 2013

Gathering "Wild" Food In The City: Rethinking The Role Of Foraging In Urban Ecosystem Planning And Management, Rebecca J. Mclain, Patrick T. Hurley, Marla R. Emery, Melissa R. Poe

Environment and Sustainability Faculty Publications

Recent “green” planning initiatives envision food production, including urban agriculture and livestock production, as desirable elements of sustainable cities. We use an integrated urban political ecology and human–plant geographies framework to explore how foraging for “wild” foods in cities, a subversive practice that challenges prevailing views about the roles of humans in urban green spaces, has potential to also support sustainability goals. Drawing on research from Baltimore, New York City, Philadelphia, and Seattle, we show that foraging is a vibrant and ongoing practice among diverse urban residents in the USA. At the same time, as reflected in regulations, planning practices, …


Middle Mississippi River Islands: Historical Distribution, Restoration Planning, And Biological Importance, Teresa Cecilia Allen Nov 2013

Middle Mississippi River Islands: Historical Distribution, Restoration Planning, And Biological Importance, Teresa Cecilia Allen

Dissertations

The Middle Mississippi River’s (MMR’s) hydrology and sedimentation patterns have been altered. These activities contribute to loss of backwaters, islands, secondary channels, and reduced biodiversity. The Fish and Wildlife Service included reasonable and prudent alternatives (RPAs) in its Biological Opinion for the Operation and Maintenance of the Nine-Foot Channel Navigation Project. These RPAs mandate dike notching and island building to increase habitat diversity. My first goal was to examine changes in the number and relative location of islands from 1797 to 2003. I found that the total number of islands increased, the number of central islands decreased, and the number …


A Data-Based Method For Harmonising Heterogeneous Data Modelling Techniques Across Data Mining Applications, Kassim S. Mwitondi, Raed A. T. Said Nov 2013

A Data-Based Method For Harmonising Heterogeneous Data Modelling Techniques Across Data Mining Applications, Kassim S. Mwitondi, Raed A. T. Said

Journal of Statistics Applications & Probability

We propose an iterative graphical data visualisation algorithm for optimal model selection. The algorithm is implemented on three domain-partitioning techniques - decision trees, neural networks and support vector machines. Each model is trained and tested on the Pima Indians and Bupa Liver Disorders datasets with the performance being assessed in a multi-step process. Firstly, the conventional ROC curves and the Youden Indexare applied to determine the optimal model then sequential moving differences involving the fitted parameters - true and false positives – are extracted and their respective probability density estimations are used to track their variability using the proposed algorithm. …


A Mild Winter: The Status Of Environmental Preliminary Injunctions, Sarah J. Morath Nov 2013

A Mild Winter: The Status Of Environmental Preliminary Injunctions, Sarah J. Morath

Seattle University Law Review

Since the enactment of environmental legislation in the 1970s, the preliminary injunction standard articulated by the Supreme Court for environmental claims has evolved from general principles to enumerated factors. In Winter v. Natural Resource Defense Council, Inc., the Court’s most recent refinement, the Court endorsed but failed to explain the application of a common four-factor test when it held that the alleged injury to marine mammals was outweighed by the public interest of a well-trained and prepared Navy. While a number of commentators have speculated about Winter’s impact on future environmental preliminary injunctions, this article seeks to more precisely determine …

Sustainability Initiatives In The Workplace And Employee Productivity, Megan R. Nollman Nov 2013

Sustainability Initiatives In The Workplace And Employee Productivity, Megan R. Nollman

Research Papers

Sustainability in the workplace has the potential to affect many aspects of an organization, including employee productivity. Sustainable designers, such as LEED (Leadership in Energy and Environmental Design) professionals, claim that sustainability has numerous positive impacts in the workplace. These impacts include fewer employee sick days, increased building occupant satisfaction, and increased employee productivity. Researchers that have studied this claim have found that in many cases, sustainable initiatives and buildings have had a slight to profound positive effects on occupant satisfaction, attendance, and productivity. Lower levels of satisfaction for lighting and acoustics are common, though, because many sustainable workplaces use …

Ferguson, Luis García Barrios, Raúl García Barrios, Daniel Jaffee, Jefferson Lima, V. Ernesto Méndez,, Helda Morales, Lorena Soto-Pinto, John Vandermeer, Ivette Perfecto

Environmental Studies and Sciences

Strong feedback between global biodiversity loss and persistent, extreme rural poverty are major challenges in the face of concurrent food, energy, and environmental crises. This paper examines the role of industrial agricultural intensification and market integration as exogenous socio-ecological drivers of biodiversity loss and poverty traps in Latin America. We then analyze the potential of a food sovereignty framework, based on protecting the viability of a diverse agroecological matrix while supporting rural livelihoods and global food production. We review several successful examples of this approach, including ecological land reform in Brazil, agroforestry, milpa, and the uses of wild varieties in …
