Creativity can be nurtured based on environment and through personal, educational, professional, and cultural experiences. Creativity involves …

Soil Resilience And Arbuscular Mycorrhizal Fungi: How Fungi Can Inform Climate Change Mitigation And Adaptation In Maya Milpa Management, Courtney Mathers

Electronic Theses and Dissertations

In Mexico’s state of Yucatán, climate change impacts like prolonged and less predictable dry season length are manifesting as threats to agricultural production and food security. Nearly two thirds of Yucatán’s population is indigenous, many of whom live in rural communities that rely on rainfed subsistence agriculture (INEGI 2015). Ensuring sufficient food production in the face of climate change relies on the quality of agricultural soils. With both mismanagement of agricultural soils and climate change posing as threats to food production in Mexico, soil management practices that increase a soil quality should be identified and promoted. The primary objective of …

Phosphatidylserine Externalization On Non-Apoptotic Cells And Lipid Scramblases In C. Elegans, Julia Frondoni

Electronic Theses and Dissertations

Cell corpse clearance is key for animals to avoid inflammation and autoimmune disease. To better understand the “eat me” signal of phosphatidylserine (PS) exposure for non-apoptotic corpse clearance, we attempted to disrupt the externalization of PS on C. elegans polar bodies. The second polar body undergoes a non-apoptotic form of cell death, loses membrane integrity, externalizes PS and is cleared by embryonic cells during early development. During apoptotic and necrotic cell death, PS asymmetry is disrupted by lipid scramblases, which translocate phospholipids between the leaflets of the lipid bilayer. We found neither apoptotic nor necrotic scramblases are required for PS …

Framing, Advice-Seeking, And Medical Trust In The R/Keto Community: An Analysis Of The Medical Flair On R/Keto, Sabrina Finke

Electronic Theses and Dissertations

First created in 1921, the ketogenic diet was used as a medical intervention for children suffering from severe epilepsy. However, in recent years, this highly restrictive diet has gained mainstream popularity for a number of illness management, wellness, and weight loss uses. Despite its rise in use and popularity, mainstream medical opinion still views the ketogenic diet as a last resort for severe conditions. Using a content analysis of posts tagged with the “medical” flair on the subreddit “r/Keto,” this thesis found commonalities among posts which praised the ketogenic diet and shared positive personal anecdotes were the most likely to …

"How It Was Made", Bethany Fitts

Electronic Theses and Dissertations

This is a meta-autoethnography describing the researcher’s unfocused, rhizomatic research process throughout the COVID19 pandemic. Themes explored are the COVID19 pandemic, family, death, climate change, queer love, represenation, academia, genre, and religion. The study shows how multiple scales of grief arise during the research process. I locate this method within postcolonial theory of autoethnography that seeks to diversify structures within the academic genre.

Regenerative Agriculture Effects On Invertebrate And Bird Communities And Insect-Provided Ecosystem Services, Alex Michels

Electronic Theses and Dissertations

Conventional agricultural practices can have unintended consequences on the environment and wildlife. Insects and birds are declining at rapid rates around the world, and the current conventional agricultural paradigm is a major driver through habitat loss and the intensification of production. Invertebrates in agroecosystems provide services to both farmers and the rest of society. Regenerative systems may promote the functioning of an agroecosystem by influencing invertebrate abundance, diversity, and ecosystem services and mitigate bird and insect declines through conservation practices that increase soil health, reduce disturbances, and increase biological diversity. Here I address knowledge gaps of the effects of regenerative …

Response Of Soil Biochemical And Physical Properties To Long Term Prairie Cordgrass And Kura Clover Intercropping System, Vaishnavi Varikuti

Electronic Theses and Dissertations

Prairie cordgrass (Spartina pectinata) (PCG) is a warm-season perennial grass that can be used as a biofuel feedstock and can be grown on marginal lands. Previous studies on intercropping of a perennial legume i.e., kura clover (Trifolium ambiguum) (KC) with PCG can improve soil biochemical properties, increase biomass production, mitigate greenhouse gas (GHG) emissions while reducing the chemical fertilizer requirement. However, there is a lack of evidence about the effects of PCG production on soil biochemical and physical properties during the cropping season and at deeper soil depths in reference to support plant growth, environmental implications and enhance the soil …

Eastern Redcedar (Juniperus Virginiana L.) Encroachment On South-Central South Dakota Rangelands: Impact On Plant Communities, Austin K. Domeier

Electronic Theses and Dissertations

Grasslands historically covered 46 million km2 of Earth’s surface representing nearly 42% of the living vegetation. Encroachment of woody species onto grasslands and savannas is a widely researched global phenomenon, with eastern redcedar (ERC) (Juniperus virginiana L.) trees being the most prominent woody encroacher in the Northern Great Plains (NGP) due to the lack of prescribed fire and planted ERC escaping from shelterbelts. This encroachment poses a threat to native plant communities in terms of their reproduction, regeneration, and diversity. ERC are fierce competitors and can establish in most soil types, are drought tolerant, and prolific seed reproducers. These qualities …

The objectives of this thesis project were to 1) evaluate the influence of grain- and grass-finishing systems on carcass characteristics, proximate composition, nutritional profile, and fatty acid composition of bison bull meat, and 2) evaluate the influence of animal age on carcass characteristics of bison bulls. For objective 1, bison bulls were allowed to graze native range in north-central Nebraska until approximately 26 mo of age, when they were randomly assigned to either grain-finishing (n = 98; in an open lot with ad libitum access to prairie hay, alfalfa hay and corn for 95 d prior to slaughter) or grass-finishing …

Living In A Gradient: The Influence Of Water Temperature Variation On Development, Settling Time And Survival Of Pallid Sturgeon Larvae In The Missouri River, Maria Elizabeth Erceg

Electronic Theses and Dissertations

Pallid Sturgeon (Scaphirhynchus albus) are a federally endangered species experiencing widespread reproduction and recruitment failures. Recruitment failure is hypothesized to be caused by habitat modifications made to the Missouri River that disrupt connectivity and alter temperature profiles downstream of constructed dams. Hypolimnetic releases from Missouri River dams affect the temperature downstream, creating colder conditions during the downstream drifting phase for dispersing larvae. Understanding the influence of water temperature changes on larval development is crucial for recovery efforts. In this study, we evaluated the effects of water temperature daily heating rate on energy use, settling behavior, and growth rate of endogenously …

Therefore, our objectives of this study were to: 1) provide an overview of …

Modeling The Flow And Creep Compliance Properties Of Ice-Cream Mixes, Hiran Ranaweera

Electronic Theses and Dissertations

This work documented the influence of the protein source (MPC80 and WPC80), protein content (4-12%), and temperature (5-35ºC) on the rheological behavior (flow curve, frequency sweep, and creep-recovery) of ice-cream mixes (ICM). For each protein source, the viscosity of the ICM was satisfactorily modeled (𝑅2>0.98, 𝑅2 𝑎𝑑𝑗>0.98, and E0.99), while the recovery phase was represented by an empirical model. The percentage of recovery (%R) of the ICM significantly decreased with the protein content.

Characterization Of Porcine Respiratory Epithelial Cells And Their Innate Immune Responses To Bacterial And Viral Ligands, Yam Prasad Gautam

Electronic Theses and Dissertations

In response to a pathogenic attack, the host produces a series of defense mechanisms through various intracellular signaling pathways. The byproduct of these signaling pathways helps tackle the invading pathogen and protects the body from getting into a diseased state. This system is called the immune system. The immune system can be divided into two branches namely the innate immune system and adaptive immune system. The groups of immune cells that provide protection regardless of the pathogen specificity constitute the innate immune system. The system that acts according to the pathogen specificity is called the adaptive immune response. The production …

Students’ Perceptions Of Specific Laboratory Curricula On The Learning Experience In Chemistry Courses, Arwa Ali Alshehri

Electronic Theses and Dissertations

Laboratory courses play a key role in developing critical thinking and problem-solving skills and providing experience in certain aspects of a laboratory setting including reactions, materials, and equipment. Prior studies suggest that a laboratory course assists students toward cognitive gain on lecture content. In contrast, other studies conclude that laboratory is uncorrelated with cognitive gain on lecture content. Thus, a discord exists between researchers regarding the role that laboratory experiences play in furthering the understanding of chemistry concepts taught in lectures. The purpose of this research is to examine the impact of two different laboratory curricula on students’ performance in …

Emerging Respiratory Viral Pathogens, April Nelsen

Electronic Theses and Dissertations

Respiratory disease is arguably the most important health concern for the production animal industry [1-3]. Respiratory problems accounted for the highest mortality both in the swine and beef industries [1, 4]. Respiratory pathogens remain the most vital for swine and bovine research and disease monitoring [2, 5-7]. As pathogens, in particular viral pathogens, mutate, novel disease-causing viruses emerge, and there becomes an increasing concern and need for identification with control perimeters. One frequently identified disease syndrome is Porcine Respiratory Disease Complex (PRDC). PRDC is characterized by pneumonia of mixed respiratory infections with contributions from the environment and management practices. The …

A thesis on developing statistical models that will aid in predicting signal detection at an infrasound sensor given a noise model for the sensor. The thesis aims first to provide a means to sample from a set of atmospheric profiles effectively using a statistical model, so we can have a smaller sample space to generate transmission loss values, saving time for running propagation models. And secondly, it aims to provide a formalism for a signal detection criterion using signal-to-noise ratio. The statistical model is developed using Empirical Orthogonal Function Analysis also known as Principal Component Analysis, and Inverse Transform Sampling. …

Hiv-1 Tat And Opioids: Implications For Stress-Related Psychopathology, Salahuddin Mohammed

Electronic Theses and Dissertations

The overarching goal of this dissertation was to assess the interaction of HIV-1 Tat protein with opioids like oxycodone and the hypothalamic-pituitary-adrenal (HPA) axis and develop novel therapeutic strategy to restore HPA dysfunction in adult HIV-1 Tat transgenic mice. In the past 3 decades, combined antiretroviral therapeutics (cART) has increased the life expectancy of HIV infected individuals, with a significant decline in the number of deaths. However, due the inability of cART to sufficiently target latent CNS viral reservoirs (predominantly microglia and astrocytes to a lesser extent), approximately 50% of the HIV+ infected population contends with neurological, neuropsychiatric and neuroendocrine …

Synthesis And Charecterisation Of Methylene Blue Derivatives, Rohit Alluri

Electronic Theses and Dissertations

Since its discovery, the fluorescent dye known as methylene blue has been employed in a variety of scientific disciplines. Methylene blue (MB) for intraoperative fluorescence imaging has only lately been employed. 10-N-carbamoyl linkage modification of Methylene blue helps us in developing compounds with off-to-on fluorescence switch in the presence of near infrared (NIR). Due to its naturally induced photodamage to normal tissues and deeper penetration of lesion regions when compared to UV and visible light, near infrared (NIR) light is considered favorable among the broad radiation range. The previously synthesized derivatives are not completely soluble in water, they require other …

Cellular Mechanisms Of Igf-1 Neuroprotection After Ischemic Stroke, Cellas A. Hayes

Electronic Theses and Dissertations

Strokes are a leading cause of mortality and disability worldwide; thus, there is a dire need for new, effective pharmacotherapeutics that can be administered to reduce the burden of disease post-insult. Clinical findings have shown that insulin-like growth factor-1 (IGF-1) levels and post-stroke functional outcomes exhibit a positive relationship. Importantly, the administration of exogenous IGF-1 in rodent models of ischemic stroke attenuates neurological damage and functional deficits following stroke. Ongoing stroke damage after the initial insult is primarily induced by increased extracellular glutamate causing substantial neuronal death, increased neuro-inflammation, and leading to greater tissue loss. Evidence from our laboratory has …

Physiological Corticosterone Attenautes Gp120-Mediated Microglial Activation And Is Associated With Reduced Anxiety-Like Behavior In Gp120-Expressing Mice, Emaya Marie Moss

Electronic Theses and Dissertations

Human immunodeficiency virus (HIV) persists as a global pandemic. Despite the benefits of combinatorial antiretroviral therapies (cART), virotoxic HIV proteins are still detectable within the central nervous system and approximately half of all cART-treated patients contend with neurological impairments. The mechanisms underlying these effects are not known, but likely involve actions of virotoxic HIV proteins including glycoprotein 120 (gp120). Glycoprotein 120 is neurotoxic, in part due to its capacity to activate microglia. Corticosterone, an endogenous anti-inflammatory, has been found to attenuate neuronal death caused by gp120-induced microglial cytokine production in vitro. But, the concentration-dependent effects of corticosterone to influence microglial …

Electronic Theses and Dissertations

Retinoblastoma (RB) is a rare type of cancer that develops quickly from immature retinal cells. Enucleation, external beam radiotherapy, episcleral plaque radiotherapy, and cryotherapy have been the treatment options for the RB.

Paclitaxel (PTX) is an effective antineoplastic medication with a wide range of applications in the treatment of malignant tumors., systemic toxicity, quick elimination, and resistance limit its clinical use. Due to its limited solubility, PTX formulations have proven difficult to develop, necessitating the use of Cremophor® EL and organic solvents. Furthermore, the blood-retinal barrier prevents PTX from penetrating into the ocular tissues. The goal of this work was …

Inevitable Mortality And The Incessant Momentum Of Medicalized Death, Clifford Mckay

Electronic Theses and Dissertations

Atul Gawande, MD, affirms the inevitability of human mortality and the end of life in natural death. He decries current medical delivery’s incessant momentum toward medicalized death and recommends a meaningful conversation between doctor and patient to chart a course of care that supports what is important to the patient. But the tradition of a doctor’s dominance and a patient’s submissiveness disrupts the conversation. New definitions of both doctor and patient, and the intent to respect a patient’s autonomy, will facilitate decision-making and support patients’ values at the end of life, diminishing the momentum of medicalized death.

Investigating The Effects Of Absurd Humor And Mortality Salience On Moral Identity, Belongingness, Belief In A Just World, And Meaning In Life, Joshua Semko

Electronic Theses and Dissertations

Background: Humans have a sense of meaning, and people actively create and maintain meaning in their lives. One way humans make meaning is through fluid compensation, which is the automatic process of compensating for a threat to one’s global meaning system by temporarily strengthening other, non-related beliefs. This phenomenon has been thoroughly investigated in response to mortality salience (i.e., reminders of one’s death), but not absurd humor. This is important because little is known about the role of humor in meaning making. More research is needed to determine whether humor is a unique meaning-making process. Further, no studies have investigated …

Bridging The Gap Between Journalism 273 And Graduation, And Beyond, Mackenzie Slate Ross

Electronic Theses and Dissertations

While Journalism 273: Creative Visual Thinking is a requirement for all undergraduate students majoring in Integrated Marketing Communications and some students majoring in Journalism, there are students who end up graduating from the University of Mississippi with a desire for more knowledge of graphic design. Feedback from current students in the School of Journalism and New Media at the University of Mississippi as well as alumni of the program was gathered in two surveys to understand better how Journalism 273 benefits them and pinpoints opportunities for improvement. One hundred nineteen students who took Journalism 273 and were enrolled in the …

The Queer And Trans Ecologies Of Shakespeare's Ocean, Elijah Two Bears

Electronic Theses and Dissertations

This thesis squarely approaches the overlooked theoretical nexus of early modern blue ecologies and LGBTQIA2S+ studies to argue that Shakespeare's ocean is a deeply queer space that inspires both queer and trans effects in his characters, plays, and audiences across time. I argue you can’t fully process Shakespeare’s aquatic environments, and the broader range of his more watery plays, without accounting for the queer destabilization and trans self-fashioning that is inextricably linked with encountering the ocean, whether it is through shipwreck, ship travel, or near-drownings. This project recreates a lost world using whatever small gems of textual and historical evidence …
