Development Of A Management Zone Scoring Index & Economic Returns Of Grid & Management Zone Soil Sampling In Coastal Plain Soils Of The Southeastern United States, Alexander M. Coleman

All Theses

Precision agriculture seeks to improve conventional farming practices through the use of Management Zones (MZ). There are many ways to create MZs and it’s not always easy to decide which MZ would provide optimal results for the specified application. Good MZs should have little variation within a zone, but large differences when compared to other zones. Previous research has been inconsistent on the ability of MZs to capture yield variation. One objective of this research was the development and application of the Management Zone Scoring Index (MZSI) to assess efficacy of 13 zone delineation methods at capturing yield data variation. …

Evaluation Of Α-Pyrrolidindovalerophenone (Α-Pvp) And Its Isomers In Male And Female Sprague-Dawley Rats Trained To Discriminate Mdpv, Kaley Cargile

Masters Theses

Recreational use of synthetic cathinones, 3,4-methylenedioxypyrovalerone (MDPV) and α‐pyrrolidinovalerophenone (α‐PVP), has become increasingly popular, thus prompting characterization of their behavioral and neurochemical effects. MDPV has been studied for several years now, though there is still much unknown about α‐PVP, and its isomers. The primary objective of this study was to characterize the discriminative effects of α‐PVP and its isomers in comparison to MDPV. Male and female Sprague-Dawley rats were trained to discriminate 0.5mg/kg MDPV from saline injections under a fixed ratio 20 (FR 20) schedule of food reinforcement. Substitution tests were conducted with MDPV (0.05-0.5mg/kg), α‐PVP (0.05-0.5mg/kg), (S)-α‐PVP (0.05-1mg/kg) and …

Acetyl-Coa And Metabolite Fluxes Regulate White Adipose Tissue Expansion, Jessica B Felix, Aaron R Cox, Sean M Hartig

Faculty, Staff and Students Publications

White adipose tissue (WAT) depends on coordinated regulation of transcriptional and metabolic pathways to respond to whole-body energy demands. We highlight metabolites that contribute to biosynthetic reactions for WAT expansion. Recent studies have precisely defined how byproducts of carbohydrate and lipid metabolism affect physiological and endocrine functions in adipocytes. We emphasize the critical emerging roles of short-chain fatty acids (SCFAs) and tricarboxylic acid (TCA) cycle metabolites that connect lipogenesis to WAT energy balance and endocrine functions. These insights address how adipocytes use small molecules generated from central carbon metabolism to measure responses to nutritional stress.

‘Site Of Contact Genotoxicity’ Assessment For Implants - Potential Use Of Single Cell Gel Electrophoresis In Biocompatibility Testing Of Medical Devices, T. S. Kumaravel, B. Brabu, N. Parthiban, S. S. Murugan, A. N. Jha

School of Biological and Marine Sciences

Toxicological risk assessment of medical devices requires genotoxicity assessment as per ISO 10993, Part 3, which is designed to address gene mutations, clastogenicity and/or aneugenicity endpoints. ‘Site of contact genotoxicity’ is a potential genotoxic risk especially for medical implants, that is currently not addressed in biocompatibility standards. We therefore performed initial validation study on the use of alkaline single cell gel electrophoresis (comet assay) for detecting ‘site of contact genotoxicity’ of medical devices, using test items made of acrylic implants impregnated with ethyl methanesulphonate (EMS). Comet assay detected increased DNA migration at the site of implantation, but not in the …

Humanitarian Response For Internally Displaced Women And Children In North-East, Nigeria, Aitiya Simon

International Studies (MA) Theses

The insurgency created by Boko Haram in the North-Eastern Region of Nigeria has displaced over 2.7 million people. From 2009 to the present day, millions of women and children are forced to seek refuge in Internally Displaced Persons (IDP) camps in Borno, Adamawa, and Yobe state. The focus on women and children is because women and children account for the majority population in the displaced camps. IDP camps provide a place of refuge for people however, critics have recognized the local and international communities' failure to improve the camps' conditions especially for the women and children.

This thesis focuses on …

Life, Love, And Loss: Redefining The Trauma, Samantha Crystal Rae Barnette

Graduate Theses/Dissertations

This thesis begins with a critical introduction analyzing the use of defamiliarization and the Dostoevskian hero in literature as a catalyst for a change in perception for victims of trauma. I create a relationship between the theories of Viktor Shklovsky and Mikhail Bakhtin as applied to both my own and published works. Short stories from Carmen Maria Machado and Marly Swick and Margaret Atwood’s novel The Handmaid’s Tale help to situate my own writing within this theoretical approach. The basis of my hypothesis lies in the blurred effect that trauma can have on the individual, causing an automatic response to …

Estancia Vs. Kentucky 31: Examining Leaf Nutrient Content Of Established Tall Fescue, Macie W. Clark

Graduate Theses/Dissertations

In 2020 Missouri ranked third in beef cattle production and second in hay production. As part of the fescue belt of the United States, Missouri’s agricultural industries rely on tall fescue (Lolium arundinaceum Schreb.) as a main forage crop. Two major disorders in cattle grazing tall fescue are fescue toxicosis and grass tetany. Fescue toxicosis occurs when animals consume toxic ergot alkaloids produced by an endophyte within the tall fescue plants. The most commonly grown tall fescue variety, Kentucky 31, is infected with the toxic endophyte. Varieties containing a novel non-toxic endophyte, such as Estancia, have been developed to …

Sodium Pyruvate Ameliorates Influenza A Virus Infection In Vitro And In Vivo, Jessica M. Reel

Graduate Theses/Dissertations

Pyruvate is produced in duplicate at the end of glycolysis in addition to ATP and NADH. Pyruvate is the metabolite of choice in most cells, whether obtained exogenously or endogenously. Recently we found that the addition of pyruvate’s conjugate base, sodium pyruvate, to cell culture media dampened the immune response to influenza A virus (IAV) infection in cultured innate immune cells. Thus, I decided to investigate the mechanism and potential for treatment of IAV. In vitro using bone marrow derived macrophages that were infected with IAV we found that adding sodium pyruvate to the media decreased immune signaling pathways through …

Saga Beyond The Gate: Chapter One, The Coming Of The Gate Ghost, Tristan B. Miller

Graduate Theses/Dissertations

“Saga Beyond the Gate: Chapter One, the Coming of the Gate Ghost” explores performance sculpture used as religious ritual. My work emphasizes ritual, creation myths, relics, physical manifestations of lived religion, and the power of narrative belief. One often turns to religion, science, or spirituality, to seek answers to questions about being a conscious entity, and one’s journey to the end. This saga uses scripts from all three of these schools of thought, placing the world of the Gate Ghost into tangible reality, as a play on a stage. Artefacts represent objects of power and mystery. Characters embody morality tales, …

Observing Changes In Vegetable Production Through Alternative Agricultural Practices, Austin Grey Livingston

Graduate Theses/Dissertations

Locally, responsibly grown produce is becoming more popular as consumers are shifting to organic products or those obtained at a local farmer’s market. The importance of soil health through conservation practices is increasing as the negative effects of industrial production are apparent. The over-application of synthetic fertilizers, soil erosion from wind and water, and nutrient leaching in high vegetable production areas has initiated a need for the investigation of alternative management practices. The main objective of this study is to evaluate the effects of tillage and cover crops in the production of green beans and okra. In 2019 and 2020, …

Pattern Based Classification Of Chronic Kidney Disease Patients, Melissa Megan Moreno Cole

Theses and Dissertations

We apply a pattern-based classification method to identify clinical and genomic features associated with the progression of Chronic Kidney Disease (CKD). We analyze the African-American Study of Chronic Kidney Disease with Hypertension (AASK) dataset and construct a decision-tree classification model, consisting 15 combinatorial patterns of clinical features and single nucleotide polymorphisms (SNPs), seven of which are associated with slow progression and eight with rapid progression of renal disease among AASK patients. We identify four clinical features and two SNPs that can accurately predict CKD progression. These features are validated with using sophisticated machine learning techniques including Random Forest, Nearest Neighbor, …

Evaluation Of Nutrient Solutions Produced From Aqueous Extracts And Decomposition Products Of Organic Waste Materials On The Plant Growth Performance In Hydroponics, Noura Said Al Nuaimi

Theses

Hydroponic plant production involves the cultivation of plants in absence of soil. In this system, the supply of the plant root with water and nutritional elements occurs via a nutrient solution made of inorganic salts. Hydroponic plant cultivation often achieves higher yields, water use efficiencies and quality of crops compared with soil production. In addition, it renders the farming system independent from soil properties. However, the currently available systems rely on the steady input of non-renewable inorganic salts. Unlike soil-based systems, hydroponics, so far, do not offer feasible opportunities for recycling nutritional elements from within crop residues or organic waste …

Examining Awareness And Identification Procedures Of Students With Specific Learning Disabilities In Uae Elementary Government Schools, Hana Aidrous Omar

Theses

Specific Learning Disability (SLD) is the most prevalent type of disability. Many students have been incorrectly identified as having SLD when, in fact, they have a different issue or disability. Other students with serious academic problems have been ignored and have not been evaluated. This study, therefore, examines the procedures used to identify students with SLD in UAE elementary government schools. The purpose of this study is twofold: (a) to examine the diagnostic procedures and steps that UAE elementary government schools follow to identify and place students with SLD and (b) to investigate school professionals’ awareness of SLD. A mixed …

Stability Of Blood Lead Levels In Children With Chronic Low-Level Lead Absorption, Michelle Del Rio

Open Access Theses & Dissertations

Background and Significance: Despite the many historical efforts by the U.S. to reduce lead (Pb) in the environment, childhood Pb poisoning continues to be a public health issue today. Pb has been identified as a child hazard because children are highly vulnerable to the effects even at lower levels of exposure (blood lead levels (BLLs) < 10 μg/dL), and these effects can be physical, cognitive, and behavioral. Current state and federal blood lead level screening guidelines for identifying exposed children are based on assumptions that BLLs < 10 μg/dL will remain stable or decline over time (with age); disregard the effects of lowest-range Pb exposure; and disregard Pb levels in children older than approximately age 6. We have observed in past clinical studies that in one U.S./Mexico border community, children in high-risk neighborhoods experienced substantially higher proportions of elevated blood lead levels (CDC reference level of ≥ 5 μg/dL) than the rest of the U.S., and a large proportion of children had detectable blood lead levels. To test current policy assumptions regarding child blood lead level screening, this study examined whether time and/or other possible factors over time, predicted child blood lead levels in children with chronic low-level Pb absorption. Whether time was a significant predictor was examined, and also whether age, sex, and living in families with incomes below the U.S. poverty line, living in an older home, and living near industries predicted child blood lead levels.

Aims and Objectives: Changes in current policy must be evidence-based. The over-arching goal of this study was to test current assumptions that one blood lead level test is sufficient to rule out child lead exposure, and that lead exposure and risk of lead exposure, reliably …

Regulating The Impending Transformation Of The Meat Industry: "Cultured Meat", Jaden Atkins

Journal of Technology Law & Policy

Imagine the ability to create up to 80,000 burgers from one single sample of a cow’s leg and a simple serum. The impacts would all be enormous, from the reduction in land use and resulting environmental impact, to victories for animal rights, to human health impacts. This may sound far-off, but it could soon be our reality. Cell-cultured or simply “cultured” meat is in development and is expected to be widely available in the next few years. While this technology’s potential impacts are incredible, cultured meat challenges our current framework of food regulation, requiring new solutions to old problems.
