Evaluating The Potential Of Genomic Selection For Grain Yield And Yield Component Traits In South Dakota Winter Wheat, Dante Koupal

Electronic Theses and Dissertations

Wheat (Triticum aestivum L.) is a major cereal crop worldwide, but recent gains in grain yield (GY) have not kept pace with projected demand. GY is a highly quantitative trait with low heritability that requires multi-year, multi-location phenotyping, limiting selection efficiency. Targeting higher heritability yield component traits, such as kernel size and weight, and incorporating them into the genomic selection (GS) pipeline has the potential to accelerate genetic gain for GY. The objectives of this study were to (i) understand the relationship between GY and the kernel-size traits, including thousand kernel weight (TKW), kernel length (KL), kernel width (KW), and …

Integrating Uav-Based High-Throughput Phenotyping, Genomics, And Deep Learning To Improve Prediction Of Complex Traits In Winter Wheat, Swas Kaushal

Electronic Theses and Dissertations

Accurate prediction of complex agronomic traits such as grain yield and yield components remains a central challenge in winter wheat breeding because these traits are controlled by many genes and are strongly influenced by environmental variation. The integration of high-throughput phenotyping (HTP), genomics, and advanced machine learning approaches offers new opportunities to improve predictive accuracy and accelerate genetic gain in plant breeding. This study evaluates the use of an unmanned aerial vehicle (UAV)-based multispectral phenomics combined with genomic information, and deep learning approaches to enhance the prediction of grain yield (GY), test weight (TW), grain protein content (GPC), and tiller …

Electronic Theses and Dissertations

Respiratory disease caused by Mycoplasma ovipneumoniae is among the most significant threats to bighorn sheep (Ovis canadensis) conservation in North America. In July 2021, contact between bighorn sheep rams and domestic sheep north of Badlands National Park (BADL), South Dakota, USA introduced M. ovipneumoniae into the Badlands bighorn sheep meta-population, triggering an epizootic that reduced the population by approximately 80%. I evaluated the post-outbreak status of this population through two complementary studies conducted from 2023 to 2025. In Chapter 1, I quantified disease prevalence, adult survival, lamb recruitment, and population growth rate (λ) using serial quantitative polymerase chain reaction (qPCR) …

Evaluating Supplementation Strategies Using Precision Livestock Technologies And Energy Based Models In Developing Beef Heifers Grazing Dormant Rangeland, Kali-Jo Bentz

Electronic Theses and Dissertations

Replacement beef heifer development in extensive grazing systems is challenged by variation in forage quality, supplement intake, and animal behavior, all of which influence the ability to achieve targeted growth prior to breeding. Precision livestock technologies (PLT) enable continuous monitoring of individual animal performance, while energy-based nutritional models support individualized supplementation. However, their application under extensive grazing conditions remains poorly understood. Therefore, the objectives of this thesis were to (1) evaluate heifer utilization of multiple precision livestock technologies and their relationship with animal performance and (2) evaluate the accuracy of an individualized energy-based supplementation model by comparing predicted supplement allotments …

Fda After Loper Bright, Erika Lietzan

SMU Law Review

Loper Bright Enterprises v. Raimondo, which overruled the Chevron, U.S.A. v. Natural Resources Defense Council decision from 1984, tells us that a court should determine the meaning of all statutory provisions for itself, rather than deferring to the views of the federal agencies that implement those provisions. But the overruling of Chevron may have less of an impact on the U.S. Food and Drug Administration (FDA) than conventional wisdom supposes. Most challenges to FDA action do not concern its statutory interpretations. And the agency prevailed in most cases involving statutory interpretation before the Chevron doctrine took hold. After 1984, …

My Negotiation Chatbot Toby And Pedagogical Governance, Renee Henson

Faculty Publications

The use of artificial intelligence (AI) chatbots is exploding. Adolescents increasingly prefer interactions with AI companions over peers. Adults rely on these systems for health planning, therapy, administrative assistance, nutrition guidance, and even simulated “romantic relationships.” Individuals and institutions are adopting AI tools at a pace that far exceeds the development of governance frameworks.

I developed Toby for use in my first-year Lawyering: Problem-Solving and Dispute Resolution (“Lawyering”) course to expose students to the dynamics of negotiating against an opposing counsel with a difficult personality—a type of adversary all too common in legal practice, yet difficult to prepare for. Toby …

The Effect Of Education On Green Growth And Carbon Emissions, 1990–2022, Soojeong Ahn

Electronic Theses & Dissertations (2024 - present)

The question of whether education promotes economic growth has long been a central topic in development research, and education has been linked to economic outcomes through macro-level pathways such as human capital accumulation, productivity growth, and technological diffusion. More recently, this discussion has expanded beyond economic growth to consider whether education contributes to environmentally sustainable development, particularly green growth. Green growth emphasizes the possibility of sustaining economic expansion while reducing environmental pressure (OECD, 2011; UNEP, 2011), and this study therefore examines how education is related to green growth and carbon emissions at the macro level.

At the macro level, existing …

Therapeutic Landscape Of Early Symptomatic Alzheimer's Disease Translated Into Everyday Practice For Geriatric Providers., Melissa J Bailey-Taylor, Paula Morrow, James Hendrix, Katherine E. Galluzzi, Golnosh Sharafsaleh

PCOM Scholarly Works

Alzheimer's disease (AD) accounts for 60-80% of all dementia cases. Recent advances in diagnostic biomarkers of early symptomatic AD (ie, mild cognitive impairment and mild dementia due to AD) and amyloid-targeting therapies (ATTs) have the potential to improve outcomes for patients with AD. Two ATTs (donanemab and lecanemab) are currently approved and available for use in the US. Both ATTs can slow disease progression as well as cognitive and functional decline in patients with early symptomatic AD. Treatment with ATTs is associated with specific safety concerns such as amyloid-related imaging abnormalities. Therefore, the benefit versus risk profile needs to be …

Synergistic Ph-Shift And Heat Treatment For The Recovery Of Protein Isolates From Ham Processing Brine: Evaluation Of Protein Ingredient Quality, Structure, And Functional Properties, Anim Ujong, Carlos Álvarez, Brijesh K. Tiwari, Shay Hannon, Uma Tiwari

Research Outputs: 2025-Present

Ham processing generates significant volumes of brine, a saline wastewater with untapped potential. This study compared three protein recovery methods: direct centrifugation, moderate heat treatment (75 °C), and a combined pH-shift-mild heat (PSMH) approach (65 °C). Both the PSMH method and moderate heat precipitation produced protein concentrates with the highest initial protein contents (62.15%–62.81%), which increased to 91.65%–95.59% purity after desalting, with NaCl levels reduced to <1.5%. Amino acid analysis revealed that PSMH-derived proteins had the highest total amino acid content (96.58 g/100 g). Sodium dodecyl sulphate-polyacrylamide gel electrophoresis confirmed improved recovery of muscle proteins, while Fourier transform infrared spectroscopy indicated that moderate heat treatment reduced the α-helix/β-sheet ratio. Proteins recovered using PSMH exhibited the highest water and fat binding capacities and maintained solubility across a broad pH range. They also exhibited strong foaming ability, although they showed slightly lower foam stability than proteins recovered by other methods, and they demonstrated emulsifying properties that were optimal under mildly alkaline conditions. Overall, PSMH presents a sustainable and efficient strategy for recovering functional proteins from ham brine for use in food and feed applications.
