Bio-Inspired Materials For Electrochemical Sensors, Matthew Joseph Hummel
Bio-Inspired Materials For Electrochemical Sensors, Matthew Joseph Hummel
Electronic Theses and Dissertations
Electrochemical biosensors are a rapidly growing research area that has greatly improved its specificity, accuracy, and precision in the detection of biomolecules in contemporary literature and industry alike. Typically, these systems exist in a three-electrode conformation with a working electrode functioning as the anode, a counter electrode functioning as the cathode, and a reference electrode allowing for the control of potential in the system. The method by which these sensors work is through the sharing of electrons via redox reactions with the target molecule and the working electrode or modifications on its surface. By exploiting the function of biomaterials that …
A Bitten Apple And A Bloody Key: Feminist Revisionism At The Intersection Of The Eden Myth And The Bluebeard Tale, Jacob Ford
Electronic Theses and Dissertations
This thesis investigates the feminist revisionism of the Bluebeard fairy tale through a focus on its relationship with the Eden myth. Past studies have examined the remarkable feminism of Bluebeardian literature and history, but this thesis is the first to interrogate the tale’s evolution from and alongside the Eden myth and to argue that the Bluebeard tale’s feminism is exceptional because of its ties to the Eden myth. I argue that the evolution of the intersecting revisionism of the Eden myth and the Bluebeard tale is characterized by the changing morals of the two myths—morals that, depending on the author’s …

An Exploration Of The Effects Of An Early Postpartum Intravenous Infusion With Carnosic Acid On Physiological Responses Of Transition Dairy Cows, Tainara Michelotti
Electronic Theses and Dissertations
The transition period is commonly defined as the last 3 wk before parturition to 3 wk after parturition. It is the most critical stage of the lactation cycle of high-producing dairy cows. The period consists of a complex interplay of metabolic and hormonal adaptations, inflammation, and immune activation. During the transition period, dairy cows commonly face oxidative stress, an underlying factor for dysfunctional immune response and enhanced inflammation, which can further increase the susceptibility of dairy cattle to health disorders and decrease productivity. In the last few decades, there has been an increased interest in studying alternative natural compounds with …
Auxin-Based Herbicide Program And Rhizobia Application For Weed Control And Nodulation Potential In Auxin Tolerant Soybean, Joy Amajioyi
Auxin-Based Herbicide Program And Rhizobia Application For Weed Control And Nodulation Potential In Auxin Tolerant Soybean, Joy Amajioyi
Electronic Theses and Dissertations
Foliar-applied Bradyrhizobia to V4 soybean has been reported to increase yield up to 5%. However, a stand-alone product application may not be practical. Applying with other treatments such as post-emergence herbicide application may be economical but herbicide and/or additives may be deleterious to rhizobial growth. A laboratory study investigated the impact of herbicides (glyphosate and dicamba), additives (an oil to improve absorption and spreading; and AMS used to overcome hard water impacts on glyphosate), and herbicide + additives on bacterial growth. Optical density (OD) measurements at the wavelength of 650 nm assessed solution turbidity, a surrogate measure of bacterial growth. …
Search For New Fertility Markers In Bull Sperm, Saulo Menegatti Zoca
Search For New Fertility Markers In Bull Sperm, Saulo Menegatti Zoca
Electronic Theses and Dissertations
Sperm are stored for extended periods of time in the epididymis, but upon ejaculation motility is increased and lifespan is decreased. After insemination, sperm must traverse the female barriers and undergo capacitation to complete fertilization; however, there are differences in fertility even among bulls that successfully pass a breeding soundness exam. For any potential marker of fertility, there must be variability expressed among animals. The series of studies in this dissertation had the objective 1) to evaluate differences between epididymal and ejaculated sperm and respective fluids proteins to understand increased longevity of epididymal sperm; 2) to evaluate the potential of …

Electronic Theses and Dissertations
An efficient and safe road network secures the nation’s economy and prosperity by providing public mobility and freight transport. Maintenance and rehabilitation of the road network cost billions of dollars annually. Road and highway infrastructures performance in any country is impacted by load repetitions and it is further compromised by climate attributes and extreme weather events. Damages to roads and bridges are among the infrastructure failures that have occurred during these extreme events. If maintenance and rehabilitation are not done promptly, the damages to the road caused by heavy traffic and extreme climate may lead to life-threatening conditions for road …
The Role Of Acetylcholine In Attention And Lapses In Attention In Rats Using The Mode And Deviation From Mode Of Reaction Time Latency, Scott Lee Mitchell
The Role Of Acetylcholine In Attention And Lapses In Attention In Rats Using The Mode And Deviation From Mode Of Reaction Time Latency, Scott Lee Mitchell
Electronic Theses and Dissertations
Attention Deficit-Hyperactivity Disorder (ADHD) is currently the neurodevelopmental disorder most commonly diagnosed in children in the United States, and one of the defining characteristics of ADHD is inattention. Inattention is marked by increased lapses in attention, and when assessed clinically, it has been highly correlated with reaction-time variability (RTV). Evidence from the human/clinical literature has shown an inherently higher RTV to be the primary quantitative indicator of an ADHD diagnosis. Reaction-time distributions are characterized by an asymmetrical rightward skew, and because of the prevalence of this presentation, it has been theorized that the distribution peak and skew represent separate phenomena, …

Free-Living Diazotrophs And The Nitrogen Cycle In Natural Grassland Revealed By Culture Dependent And Independent Approaches, Amrit Koirala
Free-Living Diazotrophs And The Nitrogen Cycle In Natural Grassland Revealed By Culture Dependent And Independent Approaches, Amrit Koirala
Electronic Theses and Dissertations
Biological nitrogen fixation contributes to half of the global supply of nitrogen to the biosphere. It is carried out by a diverse group of prokaryotes called diazotrophs via the nitrogenase enzyme. Nitrogen fixation research is focused on the narrow group of symbiotic diazotrophs, and the vast majority of free-living diazotrophs which contribute significantly to fixed nitrogen are yet to be explored. The goal of this research was to access phylogeny of diazotrophs considering the most up-to-date genomic information and apply that knowledge to understand the diversity of free-living diazotrophs in a natural grassland ecosystem, both by culture dependent and independent …
Effects Of Harvest Regulations And Post-Release Hooking Mortality On Walleye Populations In South Dakota, Cade Lyon
Electronic Theses and Dissertations
Harvest regulations are commonly implemented to manipulate fisheries stocks. By regulating the size and number of fish that are harvested by anglers, managers are able to meet the goals and needs of regions. However, these management actions come with the potential for negative consequences. Overexploitation due to less restrictive harvest regulations can cause collapses in fisheries populations. In addition, indirect consequences such as hooking mortality brought on by length-based regulations can also be detrimental to populations. In this study, I investigated the effects of various harvest regulations on Walleye populations in three western South Dakota irrigation reservoirs: Angostura, Belle Fourche, …
Pharmacological Manipulation Of Nmda Receptor Activation And Synaptic Norepinephrine Levels: Effects On Sustained Attention In Male Rats, Zach V. Redding
Pharmacological Manipulation Of Nmda Receptor Activation And Synaptic Norepinephrine Levels: Effects On Sustained Attention In Male Rats, Zach V. Redding
Electronic Theses and Dissertations
Impaired attention is common in many neurological disorders. Normal attention promotes the selective processing of important sensory information. This selective processing relies on neurotransmitters, like glutamate, and neuromodulators, like norepinephrine, acting in frontal, parietal, and visual cortices. We tested treatments targeting the glutamatergic and noradrenergic systems using a rat model of attentional lapses.Rats were trained to respond quickly to stimuli in a two-choice reaction time task (2CRTT). Response times were split into initiation time (IT) and movement time (MT). Performance measures were derived from IT and MT distributions. IT mode represents sensorimotor processing speed when rats are attentive. IT deviation …
Absurdity Is A Distinct Aesthetic Category, Sarah Jean Szopinski
Absurdity Is A Distinct Aesthetic Category, Sarah Jean Szopinski
Electronic Theses and Dissertations
Absurdity is the sudden discomfort caused by direct awareness of your being consciousand your relation to reality. Camus’ absurdist philosophy refers to the conflict between the human desire for inherent meaning in reality and the incomprehensible and irrational nature of the universe. Facing absurdity requires confronting the absurd feeling through introspective awareness of this tension. Otherwise, you are overcome by it, succumbing to a lack of mindfulness and avoidance of the confrontation. Absurdity, especially in its aesthetic dimension, has not received the sustained attention it deserves. In this paper, I argue that due to the sustained relevance of the absurd …

An American Pilgrimage: The 1968 Poor People's Campaign Mule Train As Prophetic Social Performance, Cheston M. Bush
Electronic Theses and Dissertations
In late spring of 1968, the Southern Christian Leadership Conference (SCLC) launched a nationwide demonstration known as the Poor People’s Campaign in an effort to overcome poverty. Nine caravans representing people from around the country converged in the Capitol to petition Congress for programs that would broaden opportunities for poor Americans. This work examines the Mississippi contingent of the campaign, the Mule Train caravan, that consisted of roughly 150 people who traveled in 15 covered wagons pulled by about 40 mules. The Mule Train left Marks, Mississippi on May 13 and arrived in Washington, D.C. in time for a June …
The Meat Of The Gothic: Animality And Social Justice In United States Fiction And Film Of The Twenty-First Century, Amber Hodge
The Meat Of The Gothic: Animality And Social Justice In United States Fiction And Film Of The Twenty-First Century, Amber Hodge
Electronic Theses and Dissertations
The Meat of the Gothic: Animality and Social Justice in United States Fiction and Film of the Twenty-First Century— situates twenty-first century US gothic narratives in relation to animal studies, even as it illuminates how these narratives interrogate the effects of historic and ongoing global systems of human oppression: slavery, imperialism, and capitalism. Instead of reacting to bias by asserting a claim to a humanity perpetually imbricated in divisions of class, race, and gender, present-day authors and filmmakers create characters who form communities that include nonhuman actors as a means of generating empowerment and critique. My approach to these narratives …

The goal for this thesis was to conduct the first archaeological research at Prospect Hill plantation and to create a baseline that can be used to understand the spatial layout of the plantation and provide archaeological evidence of the enslaved people who lived there. Prospect Hill is located in southwest Mississippi and was founded in 1808 by Captain Isaac Ross. The archaeological work done at Prospect Hill was a survey of approximately 10 acres that surrounds the main house. After this survey, the artifacts were classified into two categories: chronological and functional. From this analysis, a series of patterns were …
Do Bears Prefer The Weak And The Downtrodden? The Effects Of The 52-Week Low And Financial Strength On Short-Seller Behavior, Christopher Alan Miller
Do Bears Prefer The Weak And The Downtrodden? The Effects Of The 52-Week Low And Financial Strength On Short-Seller Behavior, Christopher Alan Miller
Electronic Theses and Dissertations
This dissertation investigates the effects of a company’s financial strength on short-seller behavior around a non-information-producing event. The distance of a stock price to its 52-week high or low does not provide fundamental information, but the price extremes serve as salient price points upon which investors anchor their expectations of future stock performance. Using a large sample of daily short sales data, I investigated the effects of both the proximity to the 52-week low and the financial strength of the underlying company on short-seller behavior. I found that short-selling volume increases as the price nears its 52-week low and that …

The Validity Of Transracialism, Samantha Nichole Priest
The Validity Of Transracialism, Samantha Nichole Priest
Electronic Theses and Dissertations
In this article, the idea that transracialism could be a valid identity is considered. Standpoint epistemology presents the strongest case against transracialism as a valid identity because, according to Collin’s, racial groups have a special sense of a shared history. However, arguments for race as a social construction show how transracialism could function the same way we ordinarily feel like gender functions in our society. The violent disapproval of transracialism highlights both that ordinary usage is being challenged and that it is changing. Ultimately, narrative views of personal identity, like those suggested by Aslidair MacIntyre, and the ordinary function of …
Development Or Detriment? The World Bank And Economic Disincentives To Water Conservation: Jordan In The 1960s And 1970s, William Chase Young
Development Or Detriment? The World Bank And Economic Disincentives To Water Conservation: Jordan In The 1960s And 1970s, William Chase Young
Electronic Theses and Dissertations
This thesis examines the impact of World Bank development policies on water shortagesin the Middle East and North Africa. Analyzing primary sources from the World Bank Group Archives, I contend that in funding water development projects in the 1960s and 1970s the World Bank and its subsidiaries, the International Bank for Reconstruction and Development and the International Development Association, created economic disincentives to water conservation. These disincentives likely made authorities unable to effectively respond to water shortages that developed in the latter half of the 20th century. The Hashemite Kingdom of Jordan is used as a case study, which I …
Design And Synthesis Of Salvinorin-Based Compounds For The Opioid Receptors., Nicholas S. Akins
Design And Synthesis Of Salvinorin-Based Compounds For The Opioid Receptors., Nicholas S. Akins
Electronic Theses and Dissertations
Opioid receptors (OR) are expressed throughout both the peripheral and central nervous system and play crucial roles in the modulation of antinociception, addiction, anxiety, and depression. Salvinorin A, the main isolate of the hallucinogenic plant Salvia divinorum, is one of the most potent naturally occurring kappa opioid receptor agonists. Salvinorin A possesses beneficial effects as a therapeutic in a variety of CNS disorders, but due to its strong hallucinating, anxiogenic effects, and short half-life(t1/2), it has never advanced to clinical trials. Instead, salvinorin A has been used as an important prototype for the development of related drug candidates. Our initial …
The Black Petromodernism Of Zora Neale Hurston: Energy, Race, And Mobility, Stuart Mullet
The Black Petromodernism Of Zora Neale Hurston: Energy, Race, And Mobility, Stuart Mullet
Electronic Theses and Dissertations
This thesis situates Zora Neale Hurston and the folk communities in her oeuvre within the context of modernity’s dependencies on fossil fuels. Such a disciplinary context provides an energy footing for our understandings of African American migrations in the twentieth century—which radically transformed the nation on multiple levels—and it illuminates the communal values that undergird Black approaches to petromodern forms of mobility. Furthermore, by engaging the Black spaces of the South, my argument begins filling a gap in the energy humanities. Few scholars in this field engage deeply those populations and regions that disproportionately experience the underbelly of petromodernity and …
An In-Depth Approach For Functional Oligosaccharide Analysis, Hao Liu
An In-Depth Approach For Functional Oligosaccharide Analysis, Hao Liu
Electronic Theses and Dissertations
Heparin and heparan sulfate (Hp/HS) are linear complex glycosaminoglycans (GAGs), which are involved in diverse biological processes. Although Hp/HS GAGs influence numerous physiological and pathophysiological processes, their high degree of size polydispersity and sequence microheterogeneity make structure-function characterization challenging. In addition, it is hard to understand the structures that underlie any of the various functions with MS, because of the lability of the sulfate group during tandem mass spectrometry (MS/MS) analysis. The work presented here describes an in-depth approach for functional oligosaccharide characterization including chemical derivatization of Hp to inhibit COVID-19 infection, multi-dimensional liquid chromatography (LC) fractionation method, chemical derivatization …
Midwifery And Medicine In Britain: A Comparative View Of Midwifery And Childbearing In Scotland And England, 1650-1780, Summer Smith
Midwifery And Medicine In Britain: A Comparative View Of Midwifery And Childbearing In Scotland And England, 1650-1780, Summer Smith
Electronic Theses and Dissertations
In this dissertation I contend the female midwives and childbearing women did not passively accept the alteration of the experience of birth and the ideology surrounding it in eighteenth-century Britain. While the imposition of the man-midwife and the reframing of birth as a disease to be cured in some ways forced childbearing to shift to a medicalized event, many practices persisted from the seventeenth through the nineteenth centuries, illustrating a vein of consistency in a seemingly tumultuous period. Furthermore, the changes that did take root were not solely the purview of the male medical community, but were influenced by women …
Development And Characterization Of Albuterol Sulfate Loaded Transdermal Patches With Hme Coupled Fdm 3d Printing, Bhavana Chivukula
Development And Characterization Of Albuterol Sulfate Loaded Transdermal Patches With Hme Coupled Fdm 3d Printing, Bhavana Chivukula
Electronic Theses and Dissertations
Albuterol sulfate is a short-acting selective Beta 2 Adrenergic agonist. It is used to treat and prevent bronchospasm associated with asthma, bronchitis, and other breathing disorders. It is known to show extensive first pass metabolism and it requires frequent dosing which makes it difficult for patients to comply. To avoid these problems, transdermal route of delivery of Salbutamol was explored. Traditional methods of preparation of transdermal drug delivery systems involve the use of solvents and have multiple processing steps. To avoid the usage of solvents and decrease the processing steps, HME Coupled FDM 3D printing can be used. Different polymers …

Corn Grain Alternatives And Coated Versus Non-Coated Trenbolone Acetate And Estradiol Impants For Feedlot Finishing Animals: Influence On Growth Performance, Carcass Characteristics, Efficiency Of Dietary Net Energy Utilization, Beef Production Per Hectare And Digestiblilty, Elizabeth Buckhaus
Electronic Theses and Dissertations
Corn grain alternatives are often not used in finishing rations due to reduced caloric densities and reluctance to deviate from traditional methods. Along with optimum nutrition, cattle need to have proper implant strategies to reap maximum returns on investment. Two studies were conducted to evaluate the effects of corn grain alternatives and implant type on feedlot finishing cattle. The objective of the first study was to determine the influence of corn silage (15% or 30% dry matter inclusion), and terminal implant type (coated or non-coated) containing equal hormonal doses on animal growth performance, apparent total tract digestibility, beef production per …
