An Investigation Of The Effects Of The Second Pyrolysis On The Chemistry, Morphology, And Performance Of Iron-Nicarbazin Catalysts, Elizabeth B. Weiler

Chemical and Biological Engineering ETDs

Proton exchange membrane fuel cells offer a cost-effective, environmentally friendly, and sustainable alternative to petroleum-based power sources to the transportation sector. However, slow electrochemical reactions at the cathode of these fuel cell prevent the technology from being competitive. Iron-nitrogen-carbon based catalysts have emerged as a viable answer to this problem, yet further progress is needed to improve their performance beyond that of current state-of-the-art platinum-based catalysts, which are economically and geopolitically impractical to be a final solution. Currently, a two-step high temperature pyrolysis method has proven a promising way to synthesize iron-nitrogen-carbon catalysts for optimized performance, but there is a …

Water Quality Assessment In The Santa Fe River: Tracking Pollution Sources Via Quantitative Polymerase Chain Reaction Analysis, Hayley Aurora Hajic

Geography ETDs

Microbial contamination affects many water bodies in the United States and pathogens associated with contamination pose a threat to human health. While the nation’s lakes, streams and rivers have been monitored for decades, many still do not meet the requirements of the 1972 Clean Water Act. Due to the number of pathogens that occur in water bodies, it is not feasible to directly monitor all of them. Instead of testing for a plethora of pathogens, it is standard practice for water divisions to monitor fecal indicator bacteria (FIB) as a proxy to determine water quality. There are significant flaws, however, …

Women Near Tv's White House: Power, Gender, And Race On Us Narrative Television, Teresa Caprioglio

Foreign Languages & Literatures ETDs

CBS’s drama Madam Secretary, USA’s miniseries Political Animals, and ABC’s drama Scandal all debuted between 2012-14, each with a female protagonist working closely with the executive branch in Washington-based political circles. Each displays, however, a different engagement with political activity and its relationship to personal life and relationships and to personal identity and presentation. By examining the configurations of gender and power in Madam Secretary and Political Animals, both of which portray female Secretaries of State, this thesis addresses the visual and behavioral expectations for TV women’s access to power and visibility as women and political actors, …

The beam is generated by a ~700 kV, ~6 kA short pulse (~ 10 ns) electron beam accelerator. The design of the metamaterial SWS (MSWS) consists of a cylindrical waveguide, loaded with alternating …

Teachers’ Professional Identity Construction: A Narrative Inquiry Of Non-Native English Speaking Teachers In Saudi Arabia, Mustafa Abdo Hersi

Language, Literacy, and Sociocultural Studies ETDs

This qualitative study examineshow five in-service male non-native English speaking teachers (NNESTs) constructed and negotiated their professional identity as teachers to make meaning of their lived experiences in an EFL milieu, a Saudi Arabian university. The study also explores the challenges related to NNESTs’ teaching lives and how they negotiated them as they constructed their professional identities. I approached the studied phenomena by employing a narrative inquiry method. Data were collected through semi-structured interviews and an autobiography. The study draws on Clandinin and Connelly’s framework of three-dimensional space (temporality, sociality, and place), Bourdieu’s theory of forms of capital,and Gee’s …

An Exploration Of The Optical Detection Of Ionizing Radiation Utilizing Modern Optics Technology, Sean D. Fournier, Adam Hecht, Cassiano De Oliveira, Jeffrey B. Martin, Richard K. Harrison, Charles Potter

Nuclear Engineering ETDs

Modern ultraviolet (UV) cameras, when combined with UV-transmitting lenses/filter arrangements, can be used to detect radiation dose in air. Ionizing radiation excites nitrogen molecules in ambient air, the resulting decay includes weak emission of ultraviolet photons. Previous work has proven this phenomenon is detectable using highly-sensitive electronically cooled cameras traditionally used in astronomy for low-background imaging. While the ability to detect the presence of radiation (i.e. qualitative measurement) has been demonstrated at Sandia National Laboratories, there are several challenges in correlating images to known dose-fields (quantitative measurement). These challenges include: a low signal to background ratio, interferences due to electronic …

An Integrated Approach To Studying And Engineering Bacterial Type Ii Polyketide Core Structure Biosynthesis, Xuechen Zhu

Chemistry and Chemical Biology ETDs

Natural products including alkaloids, phenylpropanoids, polyketides, terpenoids and antibiotics provide abundant resources for drugs and drug leads. Type II polyketides (PK-IIs) are a large array of aromatic polyketides that have exhibited various bioactivities including anti-tumor, anti-cancer, anti-fungal and anti-bacteria. Based on the lengths of carbon chains and the cyclization patterns in their core structures, most bacterial PK-IIs have been classified into 6 typical classes: benzoisochromanequinone (BIQ), anthracycline (ANT), angucycline (ANG), tetracycline (TET), tetracenomycin (TCM) and pentangular (PEN). Bioengineering for diversification of PK-II core structures will generate libraries of bioactivities, which can serve the drug discovery in this family of compounds. …

Drama As Dream: Sophoclean Tragedy And The Cult Of Asclepius, Molly C. Mata

Foreign Languages & Literatures ETDs

This thesis explores tragic drama as a corresponding ritual to the incubation ritual in the cult of Asclepius and theorizes that this ritual is psychologically cathartic and healing. I argue that in Ajax and Philoctetes, Sophocles marks this cathartic ritual through nosological language, setting, and social context. In my first chapter, I explore Sophocles’ use of the language of madness (mania) and illness (nosos) in Ajax to show the exacerbation of the audience’s psychological state. Next, I show that catharsis is achieved through the negotiation and subsequent burial of Ajax. In my second chapter, I argue that Sophocles uses both …

Water Planning, Tribal Voices, And Creative Approaches: Seeking New Paths Through Tribal-State Water Conflict By Collaboration On State Water Planning Efforts, Stephen H. Greetham

Natural Resources Journal

More than a century after the Supreme Court issued its foundational Indian water law cases, only a handful of American Indian tribes have secured decrees or settlements of legally enforceable water rights. Efforts to resolve tribal water claims are typically hampered by legal and factual complexities as well as the equitable and political legacy of the United States’ western expansion. Meanwhile, those difficulties notwithstanding, planners are refining their methodologies and rising to new challenges our water resource management systems now face (e.g., climate variability, aging infrastructure, changing use-value priorities, etc.). Signaling a departure from exclusive reliance on formal dispute resolution …

Alchemical Rulemaking And Ideological Framing: Lessons From The 40-Year Battle To Regulate Mercury Emissions From Electric Power Plants, Andrew Carter

Natural Resources Journal

Environmental mercury has long been linked to adverse health impacts on human populations. Globally ubiquitous at ambient levels in air and water, it can reach potentially unsafe levels in fish as it biologically magnifies and accumulates through aquatic and marine food webs. Vulnerable communities, including many communities of color, are particularly at risk from fish-borne mercury. Despite the fact that coal-fired electric generating units have been recognized as major sources of environmental mercury since the 1970s, and that the Environmental Protection Agency discussed possible future regulations of mercury emissions from such plants in 1975, it was not until 2014 that …

A Lot To Digest: Advancing Food Waste Policy In The United States, Alexandra Evans, Robin Nagele

Natural Resources Journal

An estimated thirty-one percent of the food grown, produced, and transported in the United States is wasted annually. This waste translates into ninety-six billion pounds of food and $165 billion in lost economic value. Food waste occurs at all phases of the supply chain, stretching from farm to table, and imposes substantial economic, environmental, and social costs. This Article highlights the staggering quantity of food waste in the United States and argues that certain innovative policies and market-based initiatives that strategically target the most egregious and unjustifiable types of food waste can efficiently reduce this problem. Applying a simple cost-benefit …

Investigation Of Anion And Cation Exchange Membranes For Enhancing Desalination And Power Generation In A Microbial Desalination Cell, Francisco Lopez Moruno

Civil Engineering ETDs

Microbial desalination cell (MDC) is a bioelectrochemical system capable of oxidizing organics, generating electricity and reducing the salinity content into the desalination chamber. In the first part of this study, quaternary ammonium poly(2,6-dimethyl 1,4-phenylene oxide) (QAPPO) anion exchange membranes (AEMs) with topographically patterned surfaces were assessed in a microbial desalination cell (MDC) system. The MDC results with these QAPPO AEMs were benchmarked against a commercially available AEM. The MDC with the non-patterned QAPPO AEM (Q1) displayed the best desalination rate (a reduction of salinity by 53±3 %) and power generation (189±5 mW m^-2) when compared against the commercially …

Experimental Investigation Of And Constitutive Model For The Thermo-Poro-Mechanical Deformation Of Granular Salt Under Hydrostatic Compression, Brandon C. Lampe

Civil Engineering ETDs

The influence of pore pressure and porosity on the ductile deformation of granular salt was experimentally investigated under hydrostatic compression. Confining and pore pressures were independently controlled while granular salt samples exhibited rate-dependent deformation that resulted in large decreases of sample volume and porosity. The sample deformation rates were observed to correspond with both the sample porosity and the pressure difference between the confining and pore pressures. Post-test observations revealed that the reduced porosity was caused by the solid particles deforming in a ductile manner. Insight into the cause of ductile deformation was gained by considering the local stress distribution …

International Muslim Students Within A Globalized Educational Context, Noha Ghali

Language, Literacy, and Sociocultural Studies ETDs

While previous research has revealed and documented the difficulties that international students and international Muslim students face when studying abroad, it fails to critically study and discuss the students’ perception of reasons behind these difficulties. The main aim of this study is to focus on international Muslim students and explore their social and academic experiences and challenges in a globalized educational context. Another aim is to investigate international Muslim students’ perceived reasons behind the challenges they meet, and how they negotiate such challenges. The study reviews the literature on international Muslim students in western higher education to highlight the gap …
