Optimising The Carcass Merit Of Irish Beef Cattle Using Genetic And Non-Genetic Information At The Animal And Herd Level, David Kenny Jan 2022

Optimising The Carcass Merit Of Irish Beef Cattle Using Genetic And Non-Genetic Information At The Animal And Herd Level, David Kenny

Theses

Failure of beef carcasses to achieve desirable carcass specifications represent inefficiencies within the supply chain, namely greater carcass processing costs and the inability of the resulting primal cuts to conform to high-value market specifications. Analysis of a representative sample of prime Irish beef cattle conducted in this thesis determined that 59% of cattle fail to achieve the desired carcass specifications of the supply chain at slaughter. The objective of this thesis was to use readily available information to define strategies that could help to reduce this statistic. Firstly, the likelihood of Irish beef carcasses achieving the desired carcass specifications was …

Case Study Of The Extreme High-Shear/Low-Cape, Strongly-Forced Tennessee Valley Qlcs Of 12 February 2020, Adam Weiner

Theses

High-shear, low-CAPE (HSLC) environments present unique operational forecasting challenges during the cool season across the southeastern US. Existing literature has sought to characterize the climatology of HSLC and Quasi-Linear Convective System (QLCS) environments as well as study bow echoes and mesovortices under moderate to large CAPE regimes. This case study investigates a cool season mid-Tennessee Valley severe weather event, where 200-300 J kg-1 of CAPE and 0-1 km shear of 25 m s-1 along with strong low-level forcing resulted in a severe weather event which was difficult to anticipate. Findings of this research suggest that bow echoes and …


Beyond The Supernova : Time, Space, And Utopia In Outer Wilds, Sarah Salajka Jan 2022

Beyond The Supernova : Time, Space, And Utopia In Outer Wilds, Sarah Salajka

Theses

Video games have evolved from simplistic marks moving on a screen to a diverse and inventive storytelling medium unique from other narrative forms. They allow for new methods of approaching traditional literary forms, such as the utopia. The utopian genre has seen a series of formal changes as social and historical contexts changed over time. This thesis proposes a new approach to the utopian genre borne from the current inability to imagine a future. While previous literary versions of utopia were expressed by moving forward through time or displacement through space, current social and environmental circumstances render this impossible, and …

Thermal Model Of A Centrifugal Nuclear Thermal Propulsion System, Jacob T. Keese

Theses

A numerical model was developed to study the heat transfer within the reactor of a Centrifugal Nuclear Thermal Propulsion system wherein liquid uranium heats hydrogen gas via direct-contact heat transfer. This one-dimensional, steady-state model treats the liquid uranium annulus of the centrifugal reactor as a conducting solid with internal energy generation and includes models of convection on the outside of the reactor, nonuniform energy generation from a detailed neutronics calculation, and models of bubble velocity and heat transfer. Results for three annulus geometries were compared for a variety of run conditions with the goal of maximizing the propellant output temperature …


Jury Nullification : An Extralegal History, Kim Straub Jan 2022

Jury Nullification : An Extralegal History, Kim Straub

Theses

This paper examines the changing cultural understandings of jury nullification, with a particular focus on non-judicial explanations from 1700 to 1850; how colonial executives, American legislatures, and the public understood acts of nullification. Early eighteenth-century observers tended to classify acts of jury nullification as anecdotal events placed in a strict socio-moral framework. Revolution brought about a radical new vision of nullification. Beginning in the 1750s, nullification was understood in a new hyper-political way that emphasized jury agency and independence. By the 1820s, the public returned to a socio-moral understanding of nullification. Once again, acts of nullification were explained as a …


Characterization Of Trat Protein Encoded In Incf Resistance Plasmids, Katelyn Ashley Lott Jan 2022

Characterization Of Trat Protein Encoded In Incf Resistance Plasmids, Katelyn Ashley Lott

Theses

Drug-resistant infections pose serious medical threats, and causative resistance genes spread through plasmid conjugation. The TraT protein is a virulence factor encoded in drug-resistance F-plasmids. TraT itself provides protection from conjugation, serum complement, and bacteriophages, but the protective mechanism is unknown. To facilitate mechanism studies, I developed improved purification protocols for isolation of the soluble domain of F-plasmid TraT from Escherichia coli. Wild-type TraT and two variants were obtained. TraT domain forms several types of oligomers in vitro, also observed in full-length TraT. This oligomerization is stable without membrane attachment and in broad range of salt concentrations. Purified …


'Are We Doing The Right Thing?' Utilising Security Governance To Reform The Us Drone Program, Jane Minson Jan 2022

'Are We Doing The Right Thing?' Utilising Security Governance To Reform The Us Drone Program, Jane Minson

Theses

The use of unmanned aerial vehicles, or drones, for counterterrorism purposes by the United States within its targeted killing program has been deeply controversial. Used in each presidential administration since the terrorist attacks of September 11, 2001, drones have sparked debate, in part due to their contribution to civilian deaths; their killing of high-value terrorist targets including, on at least one occasion, a US citizen; and the heightened secrecy that has surrounded the program with little formal oversight and, as such, little accountability. This thesis uses this contextual framework – with a particular focus on the administration of President Barack …


The Virtue Of Appropriate Transparency: Research Psychology And The Replication Crisis, Barry Mannolini-Winwood Jan 2022

The Virtue Of Appropriate Transparency: Research Psychology And The Replication Crisis, Barry Mannolini-Winwood

Theses

I argue that one step toward addressing the replication crisis in psychology is through the application of appropriate transparency in research communication. Drawing upon virtue epistemology, I propose that appropriate transparency can be defined as a contextually informed point between understatement and overstatement. As such, I contend that judging appropriate transparency in research psychology requires a shared research design nomenclature (RDN). As researchers’ definitions of terms related to research psychology are not necessarily identical between individuals, it is beneficial to use transparent definitions of pivotal concepts to facilitate effective communication between researchers and their audience. However, the boundaries of appropriate …


Developing Mathematical Identities: Australian Children’S Gendered Constructs In The First Formal Year Of School, Rachelle Glynn Jan 2022

Developing Mathematical Identities: Australian Children’S Gendered Constructs In The First Formal Year Of School, Rachelle Glynn

Theses

Researchers have been intrigued by the dichotomy of similar achievement levels between boys and girls but disparate mathematical attitudes, which show that girls are much less likely to enjoy or engage with mathematics or choose professions involving mathematics (Kyriacou & Goulding, 2006; Vale, 2008). Although studies have explored differences in boys' and girls' perceptions of their mathematical identity from age seven, there has not been research conducted on students as they begin school to see what gendered perceptions they bring to their mathematical learning. This study seeks to answer the question: How are girls’ and boys’ mathematical identities being informed …

Personalised Antimicrobial Dosing In Paediatric Cystic Fibrosis, Sahand Imani Jan 2022

Personalised Antimicrobial Dosing In Paediatric Cystic Fibrosis, Sahand Imani

Theses

Children with cystic fibrosis (CF) are predisposed to recurrent pulmonary exacerbations throughout their lifetime. This is characterised by an acute worsening of respiratory symptoms in the setting of bacterial infection and results in significant morbidity and mortality. Appropriate antimicrobial therapy is fundamental to management, in particular aminoglycoside antibiotics. Tobramycin is the preferred aminoglycoside of choice, usually administered intravenously for 7 to 14 days.

Tobramycin dosing can be challenging in patients with CF. This is due to the underlying pharmacokinetic derangements (e.g., volume of distribution, organ function) frequently observed in this population. Accordingly, the use of standard dosing (based on age …

An Evaluation Of The Biologics Price Competition And Innovation Act And Its Impact On Innovation In The Pharmaceutical Industry, Tara Williams

Theses

In the pharmaceutical industry, innovation is vital to bring more life-saving treatment options to patients. However, pharmaceutical manufacturers face strict safety and effectiveness guidelines set forth by the U.S. Food and Drug Administration (FDA), before being able to place their innovations on the market. In attempts to balance the need for continuous innovation and stringent regulation, policymakers created the Biologics Price Competition and Innovation Act (BPCIA) of 2009. The BPCIA allows biosimilars manufacturers to enter a shortened FDA approval pathway and provides incentives for biologics manufacturers with the aims to decrease cost and increase access to medications for patients by …

Federal Fashion: Uniform Modification, Self-Expression, And The Union Infantry Officer Of The American Civil War, Clayton Davis

Theses

The military uniforms of the American Civil War, particularly on the Union side, varied tremendously through time and location. There were an endless number of combinations􀂲myriad boots and hats, coats and jackets, insignias, and trousers. That was true for officers, especially commissioned officers, who exercised the greatest aesthetic freedom. Scattered works have broached the topic of officer uniforms, especially those of Confederate officers, though their Union counterparts have gone under the microscope also. Invariably, these works include non-regulation uniforms, either compiled by officers from separate pieces or handmade by one of the hundreds of tailors working across the nation. However, …
