The Influence Of Commercial Salmonella Vaccination Programs On Local- And Systemic-Immune Responses And Ceca Microbiome In Egg-Type Chickens, Chrysta Noelle Beck
Graduate Theses and Dissertations
Salmonella vaccination is a widely accepted practice in the United States poultry industry. These vaccines stimulate a strong humoral response to Salmonella serovars and significantly reduce Salmonella load in the bird. In general, a Salmonella vaccination program for an egg-type pullet flock consists of two administrations of a live attenuated Salmonella vaccine at 1- and 6-wk-of-age followed by one administration of a Salmonella bacterin at 12-wk-of-age. Although these vaccines are regarded as effective against paratyphoid Salmonella infections, there are incidences of breakthrough Salmonella infections and severe injection site reactions after bacterin administration. Therefore, the main objective of this dissertation was …

Current Trends In Bee Conservation And Habitat Restoration In Different Types Of Anthropogenic Habitats, Olivia Kline, Neelendra K. Joshi
Entomology and Plant Pathology Faculty Publications and Presentations
Recent declines in bee populations and ranges have been cause for concern due to the valuable pollination service that they provide. Several factors have been proposed to contribute to these declines, including habitat loss, pathogen spread, and pesticide usage, so many pollinator conservation schemes have involved the addition of pollinator-friendly habitat through wildflower plantings and artificial nesting sites. Because of this, many efforts have been made to enhance bee populations across different landscape types, including natural, agricultural, urban, and industrial areas. Many of these schemes have focused on providing habitat for bees and other animal pollinators in agricultural landscapes, but …

The Effects Of Grading Equity Practices On Students: Do Student Perceptions Of And Teachers’ Exposure To Grading Equity Practices Matter?, Sarah Ruth Morris
Graduate Theses and Dissertations
This dissertation critically examines grading practices within schools, tracing the evolution from traditional to modern approaches and highlighting the social dimensions and debates surrounding grading. Through a mixed-methods study spanning three empirical chapters, it explores students' and teachers' perceptions of grading practices, the impact of professional development (PD) on teachers' approaches to grading equity, and the resultant effects on student outcomes. Chapter Two reveals students' preferences for practices that recognize effort and support academic growth, alongside a tension between Pre-AP students' resistance and the support from students under high stress. Chapter Three finds that while PD can shift teachers' views …
Effects Of Land Cover And Land Change On Monarch Butterfly Presence Across The Conus, Chris R. Burkhart
Effects Of Land Cover And Land Change On Monarch Butterfly Presence Across The Conus, Chris R. Burkhart
Graduate Theses and Dissertations
The decline of monarch butterfly populations (Danaus plexippus L.) over the past four decades, particularly in their overwintering habitats, has raised concerns about the species' conservation. Habitat loss and modification, particularly within the contiguous United States, are attributed as one of the key drivers of this decline. However, the specific impact of land use and land cover (LULC) changes on monarch distributions remains inadequately documented. This study integrates monarch observations from multiple sources spanning 2008 to 2019 with LULC data to analyze the relationship between habitat configuration and monarch presence. Using a randomized grid sampling approach, habitat configuration metrics were …
Modification Of Time-Domain Terahertz Spectroscopy System To Polarimetry Imaging System With Application To Human Breast Cancer Surgical Specimen, Nikita Gurjar
Graduate Theses and Dissertations
Breast-conserving therapy (lumpectomy) is one of the most performed breast cancer surgeries in the United States. The best outcome of lumpectomy surgery is achieved when the surgical margins are free of cancer. When remnants of cancer are detected at the surgical margins after the initial operation, a second operation will be required to remove the cancer. Unfortunately, a significant number of patients undergo breast conserving surgery (BCS) at local hospitals that do not have access to immediate on-site pathology leading to high rates of re-excision or reoperation (greater than 30%). Therefore, there is a significant need for new intraoperative technology …

Differential Behavior Of Conformational Dynamics In Active And Inactive States Of Cannabinoid Receptor 1, Ugochi H. Isu, Adithya Polasa, Mahmoud Moradi
Chemistry & Biochemistry Faculty Publications and Presentations
Cannabinoid receptor 1 (CB1) is a G protein-coupled receptor that regulates critical physiological processes including pain, appetite, and cognition. Understanding the conformational dynamics of CB1 associated with transitions between inactive and active signaling states is imperative for developing targeted modulators. Using microsecond-level all-atom molecular dynamics simulations, we identified marked differences in the conformational ensembles of inactive and active CB1 in apo. The inactive state exhibited substantially increased structural heterogeneity and plasticity compared to the more rigidified active state in the absence of stabilizing ligands. Transmembrane helices TM3 and TM7 were identified as distinguishing factors modulating the state-dependent dynamics. TM7 …

Engineering Central Substitutions In Heptamethine Dyes For Improved Fluorophore Performance, Lei Guo, Meek Yang, Bin Dong, Seth Lewman, Alex Van Horn, Shang Jia
Chemistry & Biochemistry Faculty Publications and Presentations
As a major family of red-shifted fluorophores that operate beyond visible light, polymethine dyes are pivotal in light-based biological techniques. However, methods for tuning this kind of fluorophores by structural modification remain restricted to bottom-up synthesis and modification using coupling or nucleophilic substitutions. In this study, we introduce a two-step, late-stage functionalization process for heptamethine dyes. This process enables the substitution of the central chlorine atom in the commonly used 4′-chloro heptamethine scaffold with various aryl groups using aryllithium reagents. This method borrows the building block and designs from the xanthene dye community and offers a mild and convenient way …

Diatom Abundance In The Polar Oceans Is Predicted By Genome Size, Wade R. Roberts, Adam M. Siepielski, Andrew J. Alverson
Diatom Abundance In The Polar Oceans Is Predicted By Genome Size, Wade R. Roberts, Adam M. Siepielski, Andrew J. Alverson
Biological Sciences Faculty Publications and Presentations
A principal goal in ecology is to identify the determinants of species abundances in nature. Body size has emerged as a fundamental and repeatable predictor of abundance, with smaller organisms occurring in greater numbers than larger ones. A biogeographic component, known as Bergmann’s rule, describes the preponderance, across taxonomic groups, of larger-bodied organisms in colder areas. Although undeniably important, the extent to which body size is the key trait underlying these patterns is unclear. We explored these questions in diatoms, unicellular algae of global importance for their roles in carbon fixation and energy flow through marine food webs. Using a …

Bat Humoral Immunity And Its Role In Viral Pathogenesis, Transmission, And Zoonosis, Anne A. Roffler, Daniel P. Maurer, Tamika J. Lunn, Tarja Sironen, Kristian M. Forbes, Aaron G. Schmidt
Biological Sciences Faculty Publications and Presentations
Bats harbor viruses that can cause severe disease and death in humans including filoviruses (e.g., Ebola virus), henipaviruses (e.g., Hendra virus), and coronaviruses (e.g., SARS-CoV). Bats often tolerate these viruses without noticeable adverse immunological effects or succumbing to disease. Previous studies have largely focused on the role of the bat’s innate immune response to control viral pathogenesis, but little is known about bat adaptive immunity. A key component of adaptive immunity is the humoral response, comprised of antibodies that can specifically recognize viral antigens with high affinity. The antibody genes within the 1,400 known bat species are highly diverse, and …

Existing literature thoroughly reviews the detrimental consequences that adverse childhood experiences (ACEs) have physically, emotionally, neurobiologically, and financially. It is imperative to develop effective treatments that offer a sense of hope to children who have been impacted. The established relationship between high ACE scores and physiological hyperarousal due to emotional dysregulation is clear in the literature. This relationship indicates that taking psychophysiological measures may be an effective method of gauging the effectiveness of trauma treatments. This study measured the heart rate of a child who had experienced multiple ACEs, during 16 child-centered play therapy (CCPT) sessions, using the Empatica (E4) …

Tissue Engineered Models Of Environmental And Metabolism-Driven Cancer-Nerve Crosstalk, Emory Gregory
Tissue Engineered Models Of Environmental And Metabolism-Driven Cancer-Nerve Crosstalk, Emory Gregory
Graduate Theses and Dissertations
Purpose: Within the last 30 years, cancer-nerve interactions have garnered attention for causing patient pain, increasing the risk of recurrence, and decreasing patient prognosis. There are 2 key forms cancer-nerve crosstalk takes: perineural invasion (PNI), in which cancer cells infiltrate nerves as a route for metastasis, and tumor innervation (TI), in which neurites penetrate solid tumors to promote tumor progression. Present in vitro models of cancer-nerve crosstalk primarily include Matrigel® mouse matrix and collagen I hydrogels; whereas collagen I hydrogels neglect tumor extracellular matrix (ECM) complexity, Matrigel® is controversial for its batch-to-batch inconsistencies and inclusion of experiment-altering growth factors. Decellularized …

Graduate Theses and Dissertations
This dissertation conducts queer eco-sensitive readings of a selection of medieval love texts in Middle English and Old French. Informed in turns by the works of feminist, queer, and ecocritical scholars, each chapter engages with a different iteration of literary queerness by bringing the representation of natural spaces and objects (especially the forest) to the fore and reading through nature depicted in the texts. The readings all share a broad goal of inviting modern audiences to play with desire and its manifestations within each text to make meaning and compel intimacy between the work and its current audience. Chapter 1 …
Development Of Iii-V And Iv Epitaxy On Sapphire Technology, Emmanuel Wangila
Development Of Iii-V And Iv Epitaxy On Sapphire Technology, Emmanuel Wangila
Graduate Theses and Dissertations
This research presents comprehensive insights into the epitaxial growth of germanium (Ge) on c-plane sapphire substrates using molecular beam epitaxy (MBE). The direct growth of Ge on sapphire typically yields three-dimensional (3D) Ge islands with diverse growth directions, multiple primary domains, and twinned crystals. However, incorporating a thin AlAs nucleation layer proves instrumental in enhancing surface and material quality. With a 10 nm AlAs layer, the achieved surface exhibits improved characteristics, including a smoother surface, single epitaxial orientation, sharper rocking curve, and a single domain. This study surpasses previous works by achieving a single primary domain and reducing twinning. Furthermore, …

Student Perceptions And Academic Performance When Taught With Multiple Active Learning Methods In A High Enrollment Undergraduate Human Physiology Course, Kate Ireton Walker
Graduate Theses and Dissertations
When instructing very large groups of students in science, it can be difficult to engage all students in the content and measure their understanding. A major unaddressed challenge in science instruction is how specifically to design and implement strategies that engender active learning particularly in high-enrollment undergraduate courses. Active learning, which represents a diverse set of strategies, may include student engagement as part of instruction through discussions, active movement, and application (Bernstein, 2018; Cavanagh, et al. 2016; Michael, 2006 & Wilke, 2003). This study was designed to provide data addressing the gap in the literature regarding how the continual implementation …
Local And Systemic Inflammatory And Antibody Responses To Salmonella-Killed Vaccines In Egg-Type Pullets, Jossie Mair Santamaria Archbold
Local And Systemic Inflammatory And Antibody Responses To Salmonella-Killed Vaccines In Egg-Type Pullets, Jossie Mair Santamaria Archbold
Graduate Theses and Dissertations
Salmonella infection in chickens is a significant and complex challenge to manage, affecting poultry health and food safety. Vaccination against Salmonella is a promising preventative approach to control flock infection and decrease the loads of this pathogen. Vaccination strategies against Salmonella often comprise the application of live attenuated and killed (inactivated) vaccines, including inactivated autogenous vaccines. Live attenuated Salmonella vaccines stimulate both cellular and humoral immunity but can potentially return to a virulent state; meanwhile, inactivated Salmonella vaccines trigger more of a humoral response and are safer since they are entirely rendered inactive. However, there is a lack of information …

The Relationship Between Phosphorus Retention And Fibroblast Growth Factor 23 In Broiler Breeders, A. D. Magnuson, N. Boonsinchai, J. Caldas, J. England, C. Coon
Poultry Science Faculty Publications and Presentations
Previous studies with broiler breeders indicate a P retention threshold when fed daily dietary levels of non-phytate P (NPP) exceeding 320 mg. Fibroblast growth factor 23 (FGF23) is a hormone secreted by osteocytes which modulates P retention and could be the biological agent which controls the P threshold in breeders. To evaluate the relationship between FGF23 and the P retention threshold, a 4 -wk study with 32 -wk -old breeders was conducted with 6 dietary treatments with daily NPP intake of 216 to 576 mg/d/h with increments of 80 mg/kg diet. The goals were 1) to …

The exponential increase in global population continues to present an ongoing challenge for livestock producers worldwide to consistently provide a safe, high-quality, and affordable source of protein for consumers. In the last 50 years, the poultry industry has spearheaded this effort thanks to focused genetic and genomic selection for feed-efficient, high-yielding broilers. However, such intense selection for productive traits, along with conventional industry farming practices, has also presented the industry with a myriad of serious issues that negatively impacted animal health, welfare, and productivity–such as woody breast and virulent diseases commonly associated with poultry farming. Bacterial chondronecrosis with osteomyelitis (BCO) …
Use Of Herbicides Coated Onto Fertilizer And Applied Over-The-Top Of Cotton, Summer Linn
Use Of Herbicides Coated Onto Fertilizer And Applied Over-The-Top Of Cotton, Summer Linn
Graduate Theses and Dissertations
Cotton (Gossypium hirsutum L.) production faces numerous challenges, many related to weed management. A herbicide application method that focuses on combing resources that producers already have access to, such as herbicide-coated fertilizers, could be a practical approach for addressing late-season control of Palmer amaranth (Amaranthus palmeri S. Wats) and other problematic weed species. Two main factors would potentially impact the efficiency of utilizing this method: cotton tolerance to the application and weed control provided by the herbicide-coated fertilizers. Some considerations could affect the efficacy of these applications, such as when the treatments are applied and when they are activated by …

Based on the simulation, the savings from reduced electricity use for ventilation and the cost of the required absorption chiller and solar thermal array for an 8-house farm were calculated. While providing cooling was found to reduce …
Approaches To Controlling Palmer Amaranth And Its Interference In Furrow-Irrigated Rice, Tanner Austin King
Approaches To Controlling Palmer Amaranth And Its Interference In Furrow-Irrigated Rice, Tanner Austin King
Graduate Theses and Dissertations
Palmer amaranth (Amaranthus palmeri S. Wats) is the most troublesome and problematic weed in most mid-southern U.S. row crop production systems. With the increased adoption of furrow-irrigated rice (Oryza sativa L.), there is a greater occurrence of Palmer amaranth due to sustained moist conditions allowing continual emergence of the weed throughout the growing season. Palmer amaranth has previously been shown to negatively affect crop yields when left unmanaged. Therefore, there is a high potential for rice yield loss due to the weed’s ability to emerge over an extended period and interfere with crop development. However, there is a lack of …
Real-Time Delphi Study: Perspectives Of An Autistic Panel On Independent Living, Celeste Michaud
Real-Time Delphi Study: Perspectives Of An Autistic Panel On Independent Living, Celeste Michaud
Graduate Theses and Dissertations
The shift from institutional living to community integration for people with disabilities, including autistic people, has been significantly influenced by legislative measures and advocacy. Despite these efforts, autistic youth and adults still experience a unique transition to independent living compared to their peers with other disabilities. Studies have reported that autistic adults are more likely to remain in the family home and less likely to live independently post-high school (Anderson et al., 2014). Existing literature and legislation illustrate a fragmented approach to defining and measuring independent living for autistic adults, often driven by non-autistic perspectives (Cribb et al., 2019). This …

Partial Immunity To Mycoplasma Gallisepticum After An Initial Infection Is Long-Lasting And Reduces Transmission In Flocks Of Canaries, Madeline Sudnick
Graduate Theses and Dissertations
Pathology during a second infection can be influenced by immunity and an increase in resistance or tolerance of individuals. Population-level differences in the ability to maintain immunity can lead to contrasting survival outcomes between groups and determine how future outbreaks will spread. However, long term wildlife disease surveillance can be challenging due to lack of infrastructure and host-pathogen specific tests. Calculating disease transmission likelihood requires understanding individual-level heterogeneity in pathology and behavior, and there is limited knowledge in understanding how populations in different stages of an epidemic will transmit disease. In Chapter I, we aim to help fill a gap …
