Response Of Running Buffalo Clover (Trifolium Stoloniferum Muhl Ex. A. Eaton) To Herbaceous Competition And Transplanting In Monongahela National Forest, Ruben E. Sabella

Graduate Theses, Dissertations, and Problem Reports (ETD)

Running buffalo clover (RBC) is a rare perennial plant that grows throughout the American Midwest and the Appalachian Mountains. It requires disturbed forests to establish and proliferate. It has been suggested that, in the past, these conditions were created by buffalo; now logging operations maintain RBC populations. However, forest managers have been looking for ways to create suitable habitat for RBC that do not involve harvesting practices. This could help create new populations in areas that cannot be logged. Once established, competing vegetation might influence RBC abundance and flowering. This study seeks to quantify this influence by measuring the vegetation …

Evaluating The Degradation Relationship Between Latent Print Impressions And Touch Dna Under Varying Environmental Conditions, Katrina M. Rupert B.S.

Graduate Theses, Dissertations, and Problem Reports (ETD)

Latent prints have been processed as a source of touch DNA evidence in the hopes of attaining partial or even full DNA profiles. However, the relationship between the latent quality and the DNA quality has not yet been fully explored, resulting in gaps in understanding how the two are connected. A common source of touch DNA is from latent print evidence, which is typically processed and photographed at a scene, and subsequently processed for DNA in the laboratory. However, there is skepticism in the forensic community around touch DNA as laboratory procedures are often manipulated beyond standard operating procedures to …

Comparison Of Skeletal Class Iii Malocclusion Facial-Shape Subtypes Between Caucasian, African American, And Hispanic Populations, Rachel Katherine Huffman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Abstract

Comparison of Skeletal Class III Malocclusion Facial-Shape Subtypes Between

Caucasian, African American, and Hispanic Populations

Rachel K. Huffman, DMD

Introduction: The development of a skeletal Class III malocclusion (Cl III) is complex as it can arise from the overgrowth of the mandible, undergrowth of the maxilla, or a combination of the two. To understand the heterogeneity of this trait clinically, studies have been conducted using facial shape analysis (e.g., Geometric morphometrics (GeoMorph)) of Caucasian and Asian populations to learn more about the principal shapes. Little is known, however, about the predominant principal shape components of Cl III within African …

Stability Properties Of A System Of Receptors In The Presence Of Attractive Domains, Basim Mohammed Al-Maliki

Graduate Theses, Dissertations, and Problem Reports (ETD)

I use mathematical modeling to understand aspects of molecular processes in living cells. Specifically, we look at the first few steps in cell signaling. Signal initiation requires that receptors located on the cell membrane bind together to form dimers. Microscopic imaging of receptors on the cell membrane revealed that receptors tend to accumulate in small areas (clusters). Studies also show that the membrane has a complex landscape consisting of domains and barriers of various origin.

Here we study the way receptor dimerization is influenced by domains on the cell membrane. Our underlying hypothesis is that the physical and chemical properties …

Enantioselective Dearomatization Facilitated By Non-Covalent Interactions Of N-Heterocyclic Carbene Catalysts And Pyridinium Salts, Jack A. Patterson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Dihydropyridines are a practical organic scaffold commonly used for their pharmaceutical properties. Nucleophilic dearomatization of pyridines has proven to be a useful method in obtaining dihydropyridines. By using N-heterocyclic carbene (NHC) organocatalysts, dihydropyridines can be synthesized with high regioselectivity of the 1,4 regioisomer over the 1,2- regioisomer but often with low enantioselectivity. By incorporating non-covalent interaction contact points, we hypothesize that enantioselectivity can be enhanced. By synthesizing numerous NHCs, each proposed to exhibit a different type of non-covalent interaction (i.e., hydrogen bonding or ion pairing), an understanding of the secondary interactions within this reaction system can be studied and …

Businesses Supposedly Held The Key To The Ada, But They Dropped The Ball: Can Marketing Be The Shot In The Arm America Needs To Bring The Spirit Of The Ada Back To Life?, Elizabeth T. Gratz

Graduate Theses, Dissertations, and Problem Reports (ETD)

This research investigates the historical and current focus of the field of marketing on the disability community and considers whether marketers can positively impact attitudes toward the group through their firm media content. My first essay uses the Rocky Road to Policy Pavers model to discuss the importance of this large and underserved consumer group, and highlights several opportunities for the marketing community to reduce existing barriers to disabled consumers in the marketplace. One way that marketers can reduce stigma and improve attitudes toward the disability community is by strategically portraying individuals with disabilities in their firm media content. My …

Effects Of Invasive Species On Ohio River Zooplankton, Samuel John Johnston

Graduate Theses, Dissertations, and Problem Reports (ETD)

Invasive species have the potential to dramatically change both aquatic and terrestrial ecosystems with rates of introduction only expected to increase across the Globe. In the Mississippi River basin filter feeding silver (Hypophthalmichthys molitrix) and bighead carp (Hypophthalmichthys nobilis) collectively known as invasive carp were introduced into aquaculture ponds where they subsequently escaped and spread to interconnected basins. Invasive carp have not yet completely established throughout the entire Ohio River. Managers recognize three distinct phases of carp invasion: establishment front, invasion front and presence front. In the Illinois River invasive carp are very well established and …

Selective Recovery Of Rare Earth Elements From Acid Mine Drainage Treatment Byproduct, Zeynep Cicek

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rare earth elements (REEs) are critical in emerging clean energy, advanced technologies, and military defense applications due to their unique physical, chemical, optical, and luminescent properties. Given the potential supply chain restrictions imposed by one country's dominance in the global REE market and the consistently growing demand for REEs, developing the US domestic REE supply chain is imperative. Thus, alternative sources are crucial to supply the demand and prevent interruption in manufacturing products that consume REEs. Concurrently, acid mine drainage (AMD) is a long-standing and widespread global challenge the mining industry encounters. AMD is generated in large volumes and continuously …

Analysis Of ‘Touch’ Dna Recovered From Metal Substrates: An Investigation Into Cfdna-Metal Interactions And The Efficacy Of Different Collection Techniques On Dna Yield, Jessica E. Thornton

Graduate Theses, Dissertations, and Problem Reports (ETD)

While several improvements have been made in recent years to optimize the recovery of ‘touch’ DNA, relatively little research has been conducted to understand the relationship between ‘touch’ DNA and the binding affinity of that DNA to metal surfaces, specifically those with a significant copper presence. Furthermore, characterization of cell-free DNA (cfDNA) and its contribution to ‘touch’ samples and those cfDNA-metal interactions from objects commonly identified at crime scenes (cartridge casings, knives, doorknobs) have been lacking. Research has identified the tendency of copper ions to intercalate with DNA helices, resulting in sample degradation among other damaging conformational changes; however, while …

Clinical And Economic Burden Of Inflammatory Chronic Conditions Among Adults In The United States: Evidence From Three Nationally Representative Surveys, Mohammad Ikram

Graduate Theses, Dissertations, and Problem Reports (ETD)

A significant proportion of adults in the United States (US) suffer from various inflammatory chronic conditions (ICCs). They include a wide range of diseases such as diabetes, rheumatoid arthritis, asthma, and chronic obstructive pulmonary diseases. ICCs are not curable, and their management typically involves medications such as NSAIDs and corticosteroids. Recently, a whole health approach that places patients’ well-being at the center is increasingly being used for better management of ICCs. The whole health approach uses an integrated approach that includes multimodal management with complementary and alternative medicines (CAM) and prescription drugs. However, the use of CAM and prescription drugs …

Impacts Of Diverse Inflammatory Stimuli On Neutrophil Behavior: Extracellular Vesicles, E-Cigarettes, And Nanoparticles, Hunter T. Snoderly

Graduate Theses, Dissertations, and Problem Reports (ETD)

Neutrophils are the body’s front-line defenders against foreign insult and are key players in a variety of inflammatory conditions. This body of work examines the role of neutrophils in promoting pathology in three distinct inflammatory contexts. In the pro-inflammatory state provoked by breast cancer, neutrophils decondense their nuclei and release cytotoxic web-like structures known as neutrophil extracellular traps (NETs). NETs form most commonly via histone modifications facilitated by the enzyme PAD4. NETs are known to be a harbinger of disease progression and promote metastasis through capture of circulating tumor cells. It was hypothesized that breast tumors release small particles known …

You've Got A Friend: Social Factors And Depressive Symptoms In Older Adults, Erika A. Fenstermacher

Graduate Theses, Dissertations, and Problem Reports (ETD)

Depression in late life has been associated with disability, lower quality of life, increased mortality, and increased risk of suicide (Fiske et al., 2009; Rodda et al., 2011). Research suggests that functional disability, which is often brought about by a medical condition, may precede depressive symptoms and may be a major factor for older adults developing depression (Ormel et al., 2002). Social support can be beneficial for both emotional and physical health (Fiori & Jager, 2021). Numerous studies found evidence that social networks, perceived and subjective social support, and satisfaction with support received moderated the relation between health problems and …

Face Image And Video Analysis In Biometrics And Health Applications, Na Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Computer Vision (CV) enables computers and systems to derive meaningful information from acquired visual inputs, such as images and videos, and make decisions based on the extracted information. Its goal is to acquire, process, analyze, and understand the information by developing a theoretical and algorithmic model. Biometrics are distinctive and measurable human characteristics used to label or describe individuals by combining computer vision with knowledge of human physiology (e.g., face, iris, fingerprint) and behavior (e.g., gait, gaze, voice). Face is one of the most informative biometric traits. Many studies have investigated the human face from the perspectives of various different …

Assessing Forest Features And Nocturnal Flying Insect Diversity As Predictors Of Eastern Whip-Poor-Will Occupancy In Foraging Habitat, Clark D. Alexander

Graduate Theses, Dissertations, and Problem Reports (ETD)

Eastern whip-poor-will (Antrostomus vociferus), an insectivorous caprimulgid, have seen an approximate 2.76% annual population decrease since the 1960s, with their breeding and foraging ecology largely unknown due to their nocturnal and cryptic behavior. I conducted research to assess abiotic and biotic variables correlated with detection, and occupancy probability, and prey species diversity on ~104,000 hectares of forest in West Virginia, owned by the private timber company Weyerhaeuser. Previous literature indicates that Eastern whip-poor-will, and their prey, require ephemeral habitat such as recently cleared and early successional forests, like those historically created by forest fires, wind shears, hurricanes, and …

Concentrated Wastewater Treatment Using A Ferric Iron-Dosed Anaerobic Upflow Sludge Blanket Reactor For Recovery Of Phosphorus And Ammonium, Carley E. Shingleton

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study evaluated the performance of a novel, ferric iron-dosed anaerobic bioreactor to recover two separate nutrient products from concentrated wastewaters -- phosphorus as vivianite (Fe₃(PO₄)₂×8H₂O) and an ammonium-containing effluent with low organics. A bench-scale upflow anaerobic sludge blanket (UASB) reactor fed with a synthetic wastewater (458.0 mg/L total organic carbon, 282.7 mg/L ammonium, and 84.4 mg/L phosphate) was dosed with a ferric chloride solution at an org. C/Fe³⁺ molar ratio ~17.5 to facilitate organic carbon oxidation coupled to iron reduction. The reactor design allowed natural settling of vivianite to its …

Weigh-In-Motion Data-Driven Pavement Performance Prediction Models, Mohhammad Afsar Sujon

Graduate Theses, Dissertations, and Problem Reports (ETD)

The effective functioning of pavements as a critical component of the transportation system necessitates the implementation of ongoing maintenance programs to safeguard this significant and valuable infrastructure and guarantee its optimal performance. The maintenance, rehabilitation, and reconstruction (MRR) program of the pavement structure is dependent on a multidimensional decision-making process, which considers the existing pavement structural condition and the anticipated future performance. Pavement Performance Prediction Models (PPPMs) have become indispensable tools for the efficient implementation of the MRR program and the minimization of associated costs by providing precise predictions of distress and roughness based on inventory and monitoring data concerning …

Influence Of Maternal Nano-Titanium Dioxide Inhalation Exposure On Cyclooxygenase Metabolites: Maternal Microvascular And Sexually Dimorphic Feto-Placental Outcomes., Julie Anne Griffith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nano-titanium dioxide (nano-TiO₂) is an engineered nanomaterial (ENM), which is widely utilized in diverse products like surface coatings, cosmetics, medical devices, and filters. Inhaled nano-TiO₂ has been demonstrated to induce pulmonary inflammation, impair microvascular function, and hinder generational reproductive endpoints. These outcomes indicate why it is important to explore gestation, as it requires timely vascular adaptations to support maternal and fetal health and development. Therefore, the central hypothesis of my dissertation is: maternal nano-TiO₂ inhalation exposure will impact maternal microvascular function and fetoplacental hemodynamics and function in a sexually dimorphic manner.

The first purpose of …

Ambient Ammonia Synthesis Via Microwave-Catalytic Materials And Plasma Chemistry, Siobhan Brown

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ammonia is critical to supporting human life on earth because of its use as fertilizer. The Haber-Bosch process to produce ammonia has been practiced for over 100 years. This process operates at high pressure and temperature to overcome the thermodynamic and kinetic limitations of the ammonia synthesis reaction thus researchers have tried to overcome it for decades. At present this process represents 1% of global energy usage and 2.5% of global CO₂ emissions. The proposed chemical looping ammonia synthesis approach seeks to reduce the environmental impact of this critical process and to elucidate microwave-catalytic principles.

This research aims to …

Epistemological Insecurity In The Anthropocene, Dustin Purvis

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation analyzes how increased mainstream awareness of climate change and other complex environmental phenomena transforms some of the basic tools we use to understand the world, including notions of agency, evidence, and causality. More specifically, this project highlights numerous contemporary literary and cultural narratives that formally and thematically depict impromptu systems of action and comprehension developed by humans confronting the unique forms of information overload that result from damaged and rapidly changing environments. Following critics like Ulrich Beck, Rob Nixon, and Stacy Alaimo, I suggest our current era of ecological instability and destructive environmental practices dictate what I refer …

The production of maple syrup is a valuable source of income and cultural identity for many rural communities throughout the central Appalachian region. Regardless, maple syrup producers face difficulties maintaining the health and productivity
of their stands due to various impacts of climate change, which have given rise to extreme weather events that exacerbate damage caused by pests and diseases. To ensure the long-term sustainability of the maple syrup industry, it is crucial to obtain a comprehensive understanding of the current biotic threats within the region, particularly woodboring insects and fungal pathogens. However, insufficient information exists regarding the community assemblages …

Experiences Of Transgender Adults Living In West Virginia, Kerry M. Drabish

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Transgender adults experience disrespect, rejection, and discrimination. This is further complicated by the incongruence and internal conflict stemming from pressure to conform to a binary system of gender. Studies describing the experiences of transgender adults are limited. Therefore, the concept coexisting between the assigned and identified self was developed to better understand how transgender adults acknowledge turmoil and marginalization in coming to embrace identity.

Purpose: The purpose of this study was twofold: (1) describe the experiences of transgender adults living in WV, and (2) gather empirical evidence about the concept coexisting between the assigned and identified self. The …

Investigation Of Early Complex Formation Of Huntingtin Protein With And Without Lipids, Alyssa R. Stonebraker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Huntington’s disease (HD) is a fatal neurodegenerative disease caused by the expansion of the polyglutamine (polyQ) domain of the huntingtin protein (htt). The expansion of the polyQ domain beyond a threshold of approximately 35 repeats triggers complex toxic aggregation mechanisms and results in altered interactions between htt and lipid membranes. Many factors modulate these processes. One such modulator includes sequences flanking the polyQ domain, most notably the first 17 amino acids at the N-terminus of the protein (Nt17), and environmental factors including the presence of membranous structures. Nt17 has the propensity to form an amphipathic a-helix in the presence of …

Governance From Below: Decentralization, Innovation, And Disaster Management In East Asia, Fatemah Muneer Nawabdin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Research on decentralization has emphasized that the distribution of power between the national and local levels has different effects on various outcomes. This dissertation aims to contribute to this discussion by shedding light on the three types of decentralization (political, fiscal, and administrative) and their effect on two main outcomes: the production of technological and intellectual innovation and COVID-19 management. I argue that decentralization – including its three types – works differently under different conditions, resulting in different outcomes. That is, fiscal and administrative decentralization empower local decision-makers to make autonomous decisions, which can be beneficial for promoting innovation, but …

Hypoxia Regulates Vessel-Modifying Macrophages And Vice Versa In Tumors, Kayla Jo Steinberger

Graduate Theses, Dissertations, and Problem Reports (ETD)

Hypoxia, or low oxygen, is a common feature of solid tumors correlating with poor survival in cancer patients. Growing tumors need a blood supply to deliver oxygen. Tumors attempt to re-acquire oxygen by forming new blood vessels from nearby, pre-existing vessels, a process known as angiogenesis. Past treatments aimed at preventing this process yielded not only disappointing results in the clinic but sometimes worsened the patient’s prognosis making the tumor more hypoxic, emphasizing the urgent need for novel targets. In tumors, angiogenesis is notoriously dysfunctional resulting in leaky, under-perfused blood vessels which cannot adequately deliver oxygen and exacerbates hypoxia. Emerging …

Continental Saline Environments Interpreted From Bedded Gypsum Of The Triassic Red Peak Formation (Chugwater Group), Northcentral Wyoming, Maya Yamei Bradford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bedded evaporites and associated red bed siliciclastics record saline lake and groundwater systems from Permo-Triassic Pangea. A major component of these red bed and evaporite systems is bedded gypsum. However, little attention has been paid to the textures of ancient gypsum. Observations of gypsum textures can refine interpretations of depositional environment and diagenetic history. This project describes textures of bedded gypsum from an outcrop of the Triassic Red Peak Formation (Chugwater Group) near Greybull, Wyoming.

This thesis uses fieldwork, petrography, and x-ray diffraction to describe an outcrop of the upper Red Peak Formation, with a focus on textures of bedded …

The Enigmatic Nature Of Toxic Masculinity: Utilizing Quasi-Photovoice Methodology To Make Distinctions Between Hegemonic And Toxic Masculinity, Taylor Elizabeth Remsburg

Graduate Theses, Dissertations, and Problem Reports (ETD)

Studies of masculinity are fraught by inconsistent and unclear definitions. A comparison of literature which uses either hegemonic or toxic masculinity as a framework reveals that toxic masculinity can be virtually indistinguishable from hegemonic masculinity. I posit that toxic masculinity is and should be distinct from hegemonic masculinity. Failure to distinguish toxic masculinity from hegemonic masculinity makes toxicity difficult, if not impossible, to operationalize. I designed a vignette survey to clarify the conceptualization and operationalization of toxic masculinity. My vignette survey, which asks participants to respond to prompts regarding both toxic masculinity and masculinity, uses quasi-photovoice methodology to allow participants …
