In Vitro Assessment Of The Antihistomonal Activity Of Methyl Jasmonate And Jasmonic Acid, Mckayla B. Williams
Poultry Science Undergraduate Honors Theses
Histomonas meleagridis is a protozoan parasite and the causative agent of histomonosis in gallinaceous birds. There are currently no approved prevention or treatment options available for histomonosis control in the United States. Mortality in affected turkey flocks can exceed 80% which highlights the urgent need for research investigating novel strategies to mitigate histomonosis in the field. The objective of this study was to evaluate the in vitro antihistomonal and antibacterial effects of of methyl jasmonate (MeJA) and jasmonic acid (JA), two plant-derived compounds, in a xenic culture of H. meleagridis. Assays were conducted using cultured H. meleagridis (PHL strain) treated …
The Black Bombers Of Ghana: Sport, Nation-Building And Pan-Africanism, 1958 To The 21st Century, Kenneth Tagoe
The Black Bombers Of Ghana: Sport, Nation-Building And Pan-Africanism, 1958 To The 21st Century, Kenneth Tagoe
Graduate Theses and Dissertations
Ghana’s Amateur Boxing Team, known as the Black Bombers, has impacted the country’s political and socio-economic development since its formation in 1958. This thesis argues that amateur boxing was one of the sports that Kwame Nkrumah, Ghana’s first president, used to promote nation-building and, more broadly, a Pan-African agenda. The team’s success in international competitions has widely projected Ghana's sporting reputation and reinforced the Pan-African principles of Black pride and excellence in the global athletics arena, and beyond. This thesis traces the origins of amateur boxing and the formation of the Black Bombers, the squad’s participation in international athletics events …

An economic analysis was also conducted to estimate the value of patties based on a* (redness) scores at different points during retail display. In Study 1, differences in L* …
End Times: American Mortality, Death Materiality, And Social Death In The 1990s, Jordan A. Savage
End Times: American Mortality, Death Materiality, And Social Death In The 1990s, Jordan A. Savage
Graduate Theses and Dissertations
The United States in the 1990s was marked by pervasive representations of death in popular culture. As death imagery became increasingly visible in entertainment, there was a growing detachment from the embodied, biological realities of death, a tension intensified by the ongoing AIDS crisis. This project explores how death is politicized and how decisions about who lives and dies are shaped by power. I draw on a constellation of theoretical frameworks that collectively illuminate the operations of state-sanctioned death and social abandonment. These include Michel Foucault’s concept of biopolitics, which examines the management of life by state power; Giorgio Agamben’s …

Three experiments were developed to assess the effects of vacuum tumble marination and aging on the proteins of chicken breast. These experiments utilized 0.75 % sodium chloride, 0.45 % phosphate, and water in a marinade. In experiment one, 270 fillets were allocated into six treatment groups, each comprising 45 fillets. Six days of storage time were used, marinating and storing the fillets in each group at a temperature of 4°C. Following each day of storage period, the fillets underwent a …
Cultural Vibrations: Student Power, International Exchange, And Black America In Mai 1968, Noah Micheal Roberts
Cultural Vibrations: Student Power, International Exchange, And Black America In Mai 1968, Noah Micheal Roberts
Graduate Theses and Dissertations
Abstract This thesis examines the prominence of Black Americans in the 68’ student movement in France. May 68’ incorporated a diverse and global network of social movements and political organizations, and had a notable connection to the American student movement. Black Americans had formed a large expatriate community in France which overlapped with many of the transnational connections forged by the student movements of 68’. This community was extremely notable in the French public sphere for popular works of literature and music, but its political contributions have been minimized or understudied. By utilizing student accounts, state and organizational records, and …

Minor League: The Journey To The Show, Collin Anderson
Graduate Theses and Dissertations
When thinking about the path an athlete takes to get to the major leagues, many think of the same process: High School, College, Professional. However, the professional level includes is more than just the MLB or NBA that people would assume. Almost all professional U.S. sports leagues have a minor league system associated with them that nearly all players pass through at one point or another. Through the lens of a documentary, this portion in an athlete’s journey will be spotlighted to show what these leagues do for them, how they help them improve, and how they prepare them to …
How To Do Things With Little Talking Tubes: Nonideal Speech Acts In The Digital Age, Anthony Holdier
How To Do Things With Little Talking Tubes: Nonideal Speech Acts In The Digital Age, Anthony Holdier
Graduate Theses and Dissertations
In this work, I develop a view about what it means to share a social or conversational context with others, as well as what is normatively entailed by doing so. Working from a broadly Austinian perspective about the moral foundations of language use and how we use words to position ourselves within social space, as well as from a generally Stalnakerian social ontology (demarcating groups by dint of aligned or overlapping sets of commitments), I present three papers demonstrating how nonidealized, ordinary language philosophy can make sense of complex, real-world phenomena. Through analyses of heretical utterances, context collapse, and chatbot …
The Effects Of Background Child-Directed And Adult-Directed Singing On Reading Comprehension Performance, Agnes Yeboah Amfo-Adu
The Effects Of Background Child-Directed And Adult-Directed Singing On Reading Comprehension Performance, Agnes Yeboah Amfo-Adu
Graduate Theses and Dissertations
Although music features in speech, such as those found in child-directed speech and song, are known to enhance language processing, the underlying mechanism of this benefit remains unclear. Prior research has primarily compared verbal materials presented in a musical, child-directed style to those in a less musical, adult-directed style, leaving it uncertain whether the benefit stems from the music style of verbal presentation or mere exposure to musical features. This study examined whether the language benefits of child-directed input persist when it is presented as background auditory stimuli rather than the primary focus of cognitive tasks. Experiment 1 found that …

Hypogonadism is understudied in men requiring solid organ transplants, particularly among lung transplant recipients. Improvement in serum testosterone levels has been reported in kidney and liver transplantation. Using the TriNetX Research Network, we performed a retrospective cohort study to evaluate the incidence of peri-transplant hypogonadism and the natural course of serum testosterone following successful lung transplantation. Men aged ≥ 18 with a lung transplant and total testosterone drawn within one year pre- and post-transplant were included. Men with receipt of testosterone therapy were excluded. A low testosterone (< 300 ng/dL) and normal testosterone (≥300 ng/dL) cohort was created before employing descriptive and analytic statistics to investigate the incidence of peri-transplant hypogonadism and the change in serum testosterone levels following lung transplantation. In our entire cohort, lung transplantation was not associated with a significant increase in post-transplant serum testosterone (329.86 ± 162.56 ng/dL pre-transplant and 355.13 ± 216.11 ng/dL post-transplant, p = 0.483). The number of men with low testosterone decreased by 9.8% following lung transplantation but was not significant, p = 0.404. In this pilot study, no significant change in the number of hypogonadal men nor serum testosterone levels was observed among men undergoing lung transplantation.
Examining Shock Wave Flow Past The Brim Of A Helmet Using Schlieren Imaging, Cody Thomas, Catherine E. Johnson
Examining Shock Wave Flow Past The Brim Of A Helmet Using Schlieren Imaging, Cody Thomas, Catherine E. Johnson
Mining Engineering Faculty Research & Creative Works
Increasing the protection a helmet provides the user from shock waves can help reduce the prevalence of blast induced traumatic brain injury (bTBI). Previous research has shown that air enters and gets trapped in the helmet-head cavity and can increase the overpressure experienced by the wearer. The brim design of the helmet has yet to be studied to understand how shock waves flow into the helmet. By studying a variety of brims, it is possible that the design can be modified to minimize shock wave flow into the helmet. This paper investigated a shock wave impacting interior and exterior facing …

Predicting Miner Localization In Underground Mine Emergencies Using A Hybrid Cnn-Lstm Model With Data From Delay-Tolerant Network Databases, Patrick Nonguin, Samuel Frimpong, Sanjay Madria
Predicting Miner Localization In Underground Mine Emergencies Using A Hybrid Cnn-Lstm Model With Data From Delay-Tolerant Network Databases, Patrick Nonguin, Samuel Frimpong, Sanjay Madria
Mining Engineering Faculty Research & Creative Works
Underground mining environments are highly hazardous, often prone to gas explosions, cave-ins, and fires that may trap miners during emergencies. The accurate, real-time localization of miners is vital for effective self-escape and rescue operations. Although the Mine Improvement and New Emergency Response (MINER) Act of 2006 mandates communication and tracking systems, most current solutions rely on low-power devices and line-of-sight methods that are ineffective in GPS-denied, dynamic subsurface conditions. Delay-Tolerant Networking (DTN) has emerged as a promising alternative by supporting message relay through intermittent links. In this work, we propose a deep learning framework that combines Convolutional Neural Networks (CNNs) …

Native Americans serve in the U.S. military at the highest rate per capita of any ethnoracial group and have elevated rates of mental health (MH) difficulties compared to other ethnoracial groups, including posttraumatic stress disorder, alcohol use disorders, and suicide. Almost half of Native Veterans live in rural areas; rurality is associated with significant barriers to MH services. Engaging in outreach with Native Veterans is an important pathway for connecting them with MH care, but the outreach process and educational materials must be culturally aligned to be more effective. We collaborated with partners at a rural Department of Veterans Affairs …
Child Abuse In Colonial America, Brian Allen
Child Abuse In Colonial America, Brian Allen
Graduate Masters Theses
Child Abuse in Colonial America is an investigation of the extent to which colonial societies were aware of child abuse and how they responded. Historians often assert that awareness of the problem did not exist in America until the mid-nineteenth century; however, the evidence uncovered suggests that cases of child abuse were recognized during the colonial period and that the societal responses differed widely. Historians of childhood document myriad social, economic, political, religious, and other cultural influences that dictate how children were treated at different times and locations, and this framework is used to interpret why the responses to child …
Radio Emission As A Probe Of Astrophysical Sources And Ionized Media, Olivia R. Young
Radio Emission As A Probe Of Astrophysical Sources And Ionized Media, Olivia R. Young
Theses
Broadband radio emission originates from a wide range of astronomical sources, such as the hot plasma of the middle solar corona and the exotic environments found around objects such as radio pulsars. For many of these sources, radio emission mechanisms and regions are not well understood, as they are complex and obscured from direct observation by the ionized media that the emission must traverse as it radiates outward toward the observer. Broadband radio waves from galactic astrophysical sources are delayed and distorted on their paths toward the Earth as they pass through the free electrons that compose a variety of …

Global Trail: Interactive Travel Memory System For Unesco Sites, Anne Sophie Beatrice Min Fa
Theses
Global Trail is an interactive mobile app designed for travellers or culture seekers to reimagine how they discover new places, engage with cultural sites and remember their travel experiences. In this digital world, photos get easily lost in phone galleries and sometimes lack an organized way to find specific memories to places visited. Through design, the app experience addresses three core objectives: Discover — users explore Unesco sites represented by badges through an interactive world map; Engage — they unlock and earn those badges when they visit those sites where they can post their memories on a community platform; and …

2020-Current year OA Pubs
BACKGROUND: Acetabular cup position is fundamental to total hip arthroplasty (THA) and surface replacement arthroplasty (SRA). Even if initial cup placement is adequate, changes in spinopelvic relationships alter functional acetabular position over time. This can lead to late complications. The purpose of this study was to examine changes in pelvic tilt and acetabular position in patients with at least 10 years of follow-up after THA or SRA.
METHODS: A retrospective review was conducted of patients from one academic practice who underwent THA or SRA and had at least 10 years of follow-up. Pelvic ratio was measured and converted to pelvic …
High-Density Lipoprotein-Associated Cholesterol Abnormalities In A Clinical Outcomes Study Of Dysferlin-Deficient Limb-Girdle Muscular Dystrophy Type R2, Zoe White, Alan Pestronk, Et Al.
High-Density Lipoprotein-Associated Cholesterol Abnormalities In A Clinical Outcomes Study Of Dysferlin-Deficient Limb-Girdle Muscular Dystrophy Type R2, Zoe White, Alan Pestronk, Et Al.
2020-Current year OA Pubs
BACKGROUND: Limb-girdle muscular dystrophy (MD) type R2 (LGMDR2, formerly LGMD2B) is an autosomal recessive form of MD caused by variants in the dysferlin gene, DYSF. It leads to slow proximal and distal muscle weakening that generally results in loss of ambulation around early adulthood but without the lethal cardiorespiratory dysfunction observed in the more severe Duchenne MD. How loss of dysferlin causes muscle fibre death is poorly understood, but recent evidence suggests a link between muscle wasting and loss of muscle cholesterol homeostasis with circulating lipoprotein abnormalities in many forms of MD.
METHODS: Cross-sectional circulating total cholesterol (CHOL), high-density lipoprotein-associated …

AIMS: The aim of the study was to identify the barriers and facilitators to healthcare access for people with Parkinson's disease (PWP) in Spanish-speaking Latin American countries (LAC) in Central and South America, to understand their drivers and consider the implications for health systems in LAC.
METHODS: Four online semi-structured focus groups were conducted with 25 PWP who provide education and/or support to PWP. The study was designed and implemented by a person with lived experience of PD. Data were mapped to an existing model of access to healthcare that incorporates provider and consumer abilities.
FINDINGS: There were multiple provider …

OBJECTIVE: Dystonia is one of the most prevalent movement disorders, characterized by significant clinical and etiological heterogeneity. Despite considerable heritability (~25%), the etiology in most patients remains elusive. Moreover, understanding correlations between clinical manifestations and genetic variants has become increasingly complex.
METHODS: Exome sequencing was conducted on 1924 genetically unsolved, mainly late-onset isolated dystonia patients, recruited primarily from two dystonia registries (DysTract and the Dystonia Coalition). Rare variants in genes previously linked to dystonia (n = 406) were examined, confirmed via Sanger sequencing, and analyzed for segregation when possible.
RESULTS: We identified 137 distinct likely pathogenic/pathogenic variants (according to ACMG …

OBJECTIVE: This study describes the structural and mechanical changes in the left atrium and left ventricle in a canine model of chronic mitral regurgitation in an attempt to identify markers linked to the onset of atrial tachyarrhythmias or left ventricle dysfunction.
METHODS: Animals underwent baseline and terminal echocardiography and cardiac magnetic resonance imaging. Under echocardiographic guidance, chordae tendinae were avulsed until there was severe mitral regurgitation, defined by regurgitant jet area to left atrium area more than 70%. At terminal surgery, rapid atrial pacing was performed to test inducibility of atrial tachyarrhythmias.
RESULTS: Twelve canines underwent mitral valve chordae avulsion …
