Application Of Cation Exchange And Nanofiltration To Treat Flue Gas Desulfurization Wastewater, Ayush R. Shahi

Civil Engineering ETDs

Flue gas emitted from coal-fired power plants is one of the major sources of sulfur and nitrogen oxides emissions to the atmosphere in the world today. Although coal use has decreased, it is still a major contributor to such emissions. The Clean Air Act in the United States established regulations for coal-fired power plants to limit SO_x and NO_x emissions into the atmosphere. To meet regulatory requirements, power plants have been using scrubbers to limit their air emissions. Flue-gas desulfurization (FGD) is a pollution prevention method that is employed to limit sulfur dioxide emissions directly in the environment …

School And Community Expectations In A Small, Rural, Northern New Mexico School, Mónica J. Martínez-Archuleta

Teacher Education, Educational Leadership & Policy ETDs

School leaders find themselves in constant reflection of their academic ranking in a time of national reform. With the No Child Left Behind Act and Every Student Succeeds Act, expectations around school and student performance are created to compare against national standards. Rural communities have undergone significant social and economic changes due to the decline of family farms, accompanied by people leaving and closing of businesses all which have dramatic effects on rural schools (Petrin, et. al. 2014). With increased attention on academic achievement at the state and federal level, it is imperative that we understand how rural schools address …

Resisting The Victimization: Examining Ideological Tensions Of Race, Gender, Sexuality And Transnationality Among First-Generation Chinese Migrant Women In U.S. Academia, Zhao Ding

Communication ETDs

This dissertation explored the daily experiences of first-generation Chinese migrant women who study and/or work in universities and colleges in the United States of America. Drawing on previous scholarship on whiteness studies and Asian American gender and sexuality studies with femiqueer perspectives, the primary goal of this study was to gain a better understanding of these Chinese migrant women’s daily experiences and negotiations with power relations concerning race, gender, and sexuality, and to challenge the dominant perceptions and constructions of Chinese/Asian women. By analyzing their narratives of everyday experiences, I found that white heteronormative patriarchal ideologies have been globally promoted, …

Natural Salinization Of The Jemez River, New Mexico: An Insight From Trace Element Geochemistry, Jon K. Golla

Earth and Planetary Sciences ETDs

The Jemez River, a tributary of the Rio Grande in north-central New Mexico, receives thermal water input from the geofluids of the Valles Caldera, an active, high-temperature, liquid-dominated geothermal system. We focus on a ∼50-km portion of the northern Jemez River. This research extends previous decadal work (Crossey et al., in prep., 2013) on major chemistry in the river by characterizing the response of 16 trace elements to geochemical contributions from geothermal waters (McCauley, Spence, Soda Dam, and Jemez Springs springs and San Ysidro mineral waters), an area with copious hydrothermal degassing (Hummingbird), and two major tributaries (Rio San Antonio …

The Chaotic Domestic: Tracing Affect In Representations Of Nation, Class, And Gender In Eighteenth-Century Laboring-Class Women’S Writing, Kelly J. Hunnings

English Language and Literature ETDs

My dissertation traces a term I call the “chaotic domestic” in the writing of a collection of eighteenth-century women laboring-class writers: Mary Barber, Mary Collier, Mary Leapor, Ann Yearsley, and Janet Little. The chaotic domestic in the hands of these writers is multi-layered and affect-driven, focusing as they do on issues regarding nation, class, and gender. As both a poetic trope and the seeming natural and dynamic state of the domestic sphere, the image of the domestic that this set of writers represents and defines is turbulent, unruly, and one that deals with the tangled web of local and global, …

A Deep Learning Approach To Uncertainty Quantification, Mst Afroja Akter

Mathematics & Statistics ETDs

In this thesis we consider ordinary differential equations (ODEs) with random parameters. We focus on Monte Carlo (MC) sampling for computing the statistics of some quantities of interest (QoIs) given by the solution of the ODE problems. We use the 4th order accurate Runge-Kutta (RK4) method as the deterministic ODE solver. We then develop a hybrid MC sampling method that combines RK4 with neural network models to efficiently compute the statistics of QoIs within a desired accuracy. We present several numerical examples to verify the accuracy and efficiency of the proposed hybrid method compared to classical MC sampling. The hybrid …

The Importance Of The Instantaneous Phase In Detecting Faces With Convolutional Neural Networks, Luis Armando Sanchez Tapia

Electrical and Computer Engineering ETDs

Convolutional Neural Networks (CNN) have provided new and accurate methods for processing digital images and videos. Yet, training CNNs is extremely demanding in terms of computational resources. Also, for simple applications, the standard use of transfer learning also tends to require far more resources than what may be needed. Furthermore, the final systems tend to operate as black boxes that are difficult to interpret.

The current thesis considers the problem of detecting faces from the AOLME video dataset. The AOLME dataset consists of a large video collection of group interactions that are recorded in unconstrained classroom environments. For the thesis, …

Racial Identity Among Latino Millennials: A Determining Factor For Political Behavior, Yoshira Macias Mejia

Political Science ETDs

This dissertation explores the political behavior of Latino millennials when compared to non-Latino millennials and Latino non-millennials. While most studies paint millennials as a monolithic generational cohort, this dissertation asks the following questions: Are Latino millennials distinct in their political behavior from millennials of other racial and ethnic groups? Do Latino millennials vary in their group identity from older Latinos, if yes does this create different patterns in their political participation when compared to other racial and ethnic millennials? The results show that linked fate varies among millennials and that Latino millennials identities are distinct from non-Latino millennials. Additionally, linked …

An Estimation Of Lower Tropospheric Mixing Derived From Inverse Modeling Of Boundary Layer Water Vapor Isotopologues On Graciosa Island, Azores, Jacquelyn M. Delp

Earth and Planetary Sciences ETDs

Recent studies have shown water vapor isotopologues to be sensitive tracers of mixing processes that govern low-cloud feedback in climate models. In this study, we develop an inverse model (MBL Mix inverse model) that uses one year of isotope and humidity observations from Graciosa Island, Azores to estimate mixing for four seasons. We show the dry end-member of the model, the lower free troposphere (LFT), can be represented using Rayleigh fractionation. Isotope observations from Graciosa Island are compared to other field locations to discuss controls on isotopic variability other than mixing. Output from the MBL Mix inverse model shows the …

Clever Cleric: Saint Wilfrid Of York And The Complexities Of Power And Authority In Seventh-Century England, Olivia E. Gannon

History ETDs

Saint Wilfrid of York was a Northumbrian bishop, abbot, and missionary. He was born in 634 and died in 709/710. His life was characterized by his landholdings that spanned territories and kingdoms, his enduring persistence to remain bishop, his monastic empire, his hostile relationships with kings, his powerful friends and supporters, and his resistance in the face of adversity. Wilfrid’s achievements were remarkable for a seventh-century bishop – a bishop deserving of recognition for his lasting impact on England. By closely examining the sources, this thesis analyzes Wilfrid’s tumultuous life and career in the form of his landholdings, his trips …

Beach Bodies: Gender And The Beach In American Culture, 1880-1940, Margaret Elena Depond

History ETDs

This dissertation argues that American beaches, within the world of leisure and pleasure, were significant contested spaces of social change and debate. Overtime, from about 1880 to 1940, social restrictions loosened at the beach, allowing men, women, and people of color to express themselves in ways that had been previously controlled, curtailed, or proscribed. The emergence of mass popular amusements at the beach attracted a wide array of the American population. Both working-class and middle-class Americans absorbed the culture of new beach attractions, such as amusement parks, piers, boardwalks, and bathhouses. In doing so, they interacted more with each other …

Facial Fluctuating Asymmetry: Developmental Origins And Implications For Long-Term Health, Katelyn Marie Rusk Phd

Anthropology ETDs

Fluctuating asymmetry (FA), characterized by random left-right deviations from perfect symmetry in anatomical structures, is a form of bilateral asymmetry that is thought to reflect underlying developmental instability (DI). DI refers to an organism’s relative ability to buffer against stochastic fluctuations in environmental conditions throughout development. FA is commonly used within evolutionary biology and anthropology as a cumulative indicator of chronic stress exposure during development and its consequences for long-term health. While the FA literature is extensive, there are two primary areas of inquiry that remain incomplete: assessing the full breadth of health correlates of FA across the human life …

Cyclic Amp Efflux Inhibition As A Potential Therapeutic Target For Acute Leukemia: Small Molecule Discovery And Validation, Dominique R. Perez

Biomedical Sciences ETDs

Evasion of apoptosis and resistance to chemotherapy are major therapeutic challenges for acute leukemias. Presumably as a means to promote cell survival, multiple elements of the cyclic AMP (cAMP) pathway are aberrantly regulated in acute leukemias. Furthermore, increased intracellular cAMP (icAMP) is known to induce apoptosis. Therefore, modulation of icAMP has long been a target in leukemias. The central hypothesis of this dissertation is that malignant cells produce and remove excess intracellular cAMP to evade apoptosis and promote survival. Consequently, inhibition of cAMP efflux could selectively trigger leukemia cell death. We designed a novel assay to assess icAMP efflux from …

Computational Investigation Of The Interactions Between Bioactive Compounds And Biological Assemblies, Tye D. Martin

Biomedical Engineering ETDs

Small, biologically active molecules with unique properties and applications are potential solutions to a wide range of threats to global health including infectious agents and neurodegenerative disease. Experimental studies on a class of oligomeric p-phenylene ethynylenes (OPEs) have shown potential both as bioactive antimicrobials and fluorescent sensing agents for tracking amyloid-β (Aβ) aggregates found in Alzheimer’s Disease (AD). A second type of small molecule with potential applications in AD therapy, curcumin, has been found to interfere with Aβ fibril growth. Curcumin also attenuates Aβ-membrane interactions and Aβ toxicity. Our goal has been to use computational techniques to better understand the …

Addressing Content, Convergent And Predictive Validity Of Implicit Pain-Related Fear In Chronic Low Back Pain, Eric S. Kruger

Psychology ETDs

Chronic low back pain (CLBP) is a common condition that can lead to emotional distress and physical disability. Fear of pain, a phobic-like response to pain, can contribute to significant avoidance behavior and is associated with disrupted physical and emotional functioning. While questionnaires remain the standard for measurement of pain-related fear, recent work has explored the use of implicit methods. This study aimed to use an implicit measure, the Implicit Relational Assessment Procedure (IRAP), to assess convergent and predictive validity of implicit pain-related fear in relation to explicit self-report measures. Seventy-four participants with CLBP were recruited and completed the pain-related …

Verification Of Stochastic Reach-Avoid Using Rkhs Embeddings, Adam J. Thorpe

Electrical and Computer Engineering ETDs

A solution to the terminal-hitting and first-hitting stochastic reach-avoid problem for a Markov control process is presented. This solution takes advantage of a nonparametric representation of the stochastic kernel as a conditional distribution embedding within a reproducing kernel Hilbert space (RKHS). Because the disturbance is modeled as a data-driven stochastic process, this representation avoids intractable integrals in the dynamic recursion of the reach-avoid problem since the expectations can be calculated as an inner product within the RKHS. An example using a high-dimensional chain of integrators is presented, as well as for Clohessy-Wiltshire-Hill (CWH) dynamics.

Evaluating Future Reservoir Storage In The Rio Grande Using Normalized Climate Projections And A Water Balance Model, Nolan T. Townsend

Earth and Planetary Sciences ETDs

We develop and implement new tools for assessing the future of surface water supplies in downstream reaches of the Rio Grande, for which Elephant Butte Reservoir is the major storage reservoir. First, a normalization procedure is developed to adjust natural Rio Grande streamflows simulated by dynamical models in downstream reaches. The normalization accounts for upstream anthropogenic impairments to flow that are not considered in the model, thereby yielding downstream flows closer to observed values and more appropriate for use in assessments of future flows in downstream reaches. The normalization is applied to assess the potential effects of climate change on …

Understanding The Learning Benefits Associated With Transcranial Direct Current Simulation Of The Right Ventrolateral Prefrontal Cortex, Benjamin C. Gibson

Psychology ETDs

Previous work has demonstrated that anodal transcranial direct current stimulation (tDCS) applied to the right ventrolateral prefrontal cortex (rVLPFC) is capable of accelerating learning of a threat identification and classification task. However, questions remain as to the cognitive mechanisms underlying this effect, and whether the observed tDCS mediated learning is specific to threatening stimuli or, rather, a more generalizable learning processes. The goal of the current project was to isolate specific aspects of the threat detection task in order to exemplify previous findings. A number of pre-test measures were included to attempt to decipher the characteristics of subjects who are …

Is Transportation Planning Effective? A Critical Review Of Long-Range Regional Transportation Planning In The United States, Razieh Nadafianshahamabadi

Civil Engineering ETDs

The Federal-Aid Highway Act requires urban areas with a population greater than 50,000 to create Metropolitan Planning Organizations (MPOs) to ensure that funding for transportation projects and programs are based on a continuing, cooperative, and comprehensive planning process. A major responsibility of each MPO is the creation of a long-range transportation plan (LRTP) that addresses the transportation needs of a metropolitan region over the next twenty years or more. While long-range regional transportation planning goals have grown to include a wide range of concerns and technical methods for evaluating planning scenarios have advanced substantially over the past 50 years, there …

Dental Hygiene ETDs

As the Native American population of the Navajo Nation, becomes affected with diabetes dental offices across the Navajo Reservation must ensure that evidence based research is being presented n the oral systemic link of diabetes and periodontal disease. The purpose of this study was to bring awareness to the important topic of the bi-directional link of diabetes and periodontal disease with Native American dental patients. This topic seems to not be valued during oral hygiene education time and so that addition of a culturally-specific educational video on the topic should add value to the message. This topic was investigated via …

Early Mississippian Ocean Anoxia Triggering Organic Carbon Burial And Enhancing Late Paleozoic Ice Age Onset: Evidence From Uranium Isotopes Of Marine Limestones, Keyi Cheng

Earth and Planetary Sciences ETDs

The Early Mississippian (Tournaisian) positive δ¹³C excursion (or TICE) is one of the largest recorded in the Phanerozoic and the organic carbon (OC) burial associated with its development is hypothesized to have driven global cooling and increased glaciation. We are testing the hypothesis that expanded ocean euxinia/anoxia drove widespread OC burial and the TICE and we are testing this hypothesis using uranium isotopes (δ²³⁸U) of Lower Mississippian marine limestones from southern Nevada as a global seawater redox proxy.

δ²³⁸U trends record a prominent mid-Tournaisian negative excursion (~0.30‰ magnitude) lasting ~1 My. The lack of …

Intratypic Genetic Variability Of Human Adenovirus Type 4: Implication For Viral Pathogenesis, Camden Roy Bair

Biomedical Sciences ETDs

Human adenovirus type 4 (HAdV-E4) is a causative agent of acute respiratory disease and conjunctivitis worldwide. Two major lineages of HAdV-E4 genomic variants have been identified by their distinct BamHI restriction profiles: prototype-like (p-like) strains and the a-like genomic variants. Recent molecular epidemiology studies have shown a predominance of a-like genomic variants detected in association with disease which suggests a-like strains have a fitness advantage or they may be more pathogenic. The impact of HAdV-E4 intratypic genetic variability on in vitro and in vivo phenotypes relevant to pathogenesis is a major gap in knowledge. I hypothesize that HAdV-E4 comprises two …

Statewise: Jurisdictional Fictions, Transnational Politics And Remaking The Nation State On The Chiapas-Guatemala Border, 1821-1899, Lean Sweeney

History ETDs

Statewise: Jurisdictional Fictions, Transnational Politics And Remaking The Nation State On The Chiapas-Guatemala Border, 1821-1899, focuses on the undrawn border between Mexico and Guatemala during the nineteenth century. I argue that this lack of national definition allowed social actors and state authorities in both Mexico and Guatemala to successfully negotiate alliances and competing territorial claims. In this space of "jurisdictional fiction," where the Mexican and Guatemalan governments' claims to authority were undermined by their lack of political, economic and military control, exiles could become political leaders, contrabandists could hold the keys and records to the customs house, displaced indigenous …

Improving Proton Pump Inhibitor Prescription Practices As A Means To Decreasing Nosocomial Infections, Jens Langsjoen

Biomedical Sciences ETDs

Proton pump inhibitors (PPIs) are commonly prescribed to treat stomach acid related illnesses, but increase the risk of hospital acquired infections. Measuring hospital PPI overuse trends and provider willingness to adopt PPI reduction interventions can inform the feasibility of reducing PPI overuse. We: (1) interviewed physicians, pharmacists and IT leaders to determine options for hospital PPI reduction, (2) analyzed electronic health record data to determine patterns of PPI overuse, and (3) surveyed providers regarding their willingness to adopt PPI reduction interventions. PPI use was inappropriate in 32% of inpatient encounters locally and 38% nationally. ICU exposure increased the odds of …

Tauopathies, Novel Optogenetic Tools, And The Future Of Artificial Intelligence In Medicine, Jessica Lee Binder

Biomedical Sciences ETDs

To this day, there is no cure for Alzheimer’s disease (AD) and related dementias (ADRD). With the daunting rise at an exponential rate of ADRD burden and related deaths, the necessity to find a new line of attack is vital. Pathological accumulation of microtubule associated protein tau in neurons is a major neuropathological hallmark of Alzheimer’s disease (AD) and related tauopathies. Attempts have been made to promote clearance of pathological tau (p-Tau) from neurons via autophagy. Transcription factor EB (TFEB) has shown to clear p-Tau from neurons via autophagy. However, sustained TFEB activation and autophagy can create burden on cellular …
