Natural Variation Of Fructose-1,6-Bisphosphatase In Colias Butterflies, Andrea Blair Stokes

Theses and Dissertations

In a process known as the evolutionary recursion, it is possible to follow how adaptation affects natural selection at successive stages of a species’ life cycle. Through studying allele and genotype frequencies of enzymes in glycolysis, a central metabolic pathway, it is possible to document how polymorphisms can shift the evolving functionality of enzymes within or among species. Fructose-1,6-bisphosphatase (FBPase) is an enzyme in gluconeogenesis that converts fructose-1,6-bisphosphate to fructose 6- phosphate. It is also known to convert the unused amino acid carbon skeletons of glycolysis into glycogen storage. Appearing to play a vital role in the acquisition, storage, and …

This study examined whether and to what extent therapists’ innovation-specific judgements (e.g., innovation is easy to use, socially desirable) were associated with intentions to use an innovation using constructs from one of the most robust theories of innovation use–the Unified Theory of Acceptance and Use of Technology (UTAUT). Method. Two aims were addressed using data collected from 95 therapists and 28 supervisors who participated in a multi-site cluster randomized trial. Therapists used either a …

Versatile And Robust Non-Iterative Coupling Algorithm For Vehicle-Structure Interaction, Arya Datta

Theses and Dissertations

The dynamic analysis of the vehicle-structure interactions can be extremely computationally expensive. A general non-iterative coupling algorithm based on the substructure approach has been presented. It retains the advantage of the substructure approach that smaller subsystems are solved instead of a large system, which is usually solved when monolithic systems are solved. However, the advantage of using this general coupling approach is that it is non-iterative in nature, instead of the substructure approach that usually uses iterative procedure. The general coupling algorithm developed has been implemented to analyze dynamic interactions between the vehicle and the structure, both in two and …

Applications Of Machine Learning For Improved Patient Selection And Therapy Recommendations, Brendan Elochukwu Odigwe

Theses and Dissertations

The public health domain continues to battle with illness and the growing need for continuous advancement in our approach to clinical care. Individuals experiencing certain conditions undergo tried and tested therapies and medications, practices that have become the mainstay and standard of care in clinical medicine. As with all therapies and medications, they don't always work the same way and do not work for everyone. Some Treatment regimens, like Hydroxyurea medication, which is commonly administered to Sickle cell anemia patients, come with some adverse side effects due to the chemotherapeutic nature of the drug. This would be particularly disappointing if …

Sources And Cycling Of Neodymium And Rare Earth Elements In The Arctic Amerasian Basin And Bering Sea, Brian D. Duggan

Theses and Dissertations

The isotopic composition of dissolved neodymium (¹⁴³Nd/¹⁴⁴Nd, expressed as εNd) behaves quasi-conservatively in the ocean and has been used as a palaeoceanographic tracer of ocean circulation. The εNd value of water masses is acquired—and often altered—during interaction with sediments along the margins; however, the processes involved in seawater εNd acquisition remains poorly characterized and quantified. Here we report the results of 349 Nd isotope and 354 rare earth element (REE) concentration measurements from 27 water column profiles across the Bering shelf and through the Arctic Amerasian Basin collected during U.S. Arctic GEOTRACES cruise HLY1502 (GEOTRACES section …

Achieving Sustainability In Urban Transit And High-Occupancy Vehicle Systems Through Emerging Technologies And Operations, Ruixiao Sun

Theses and Dissertations

It is critical to reduce road transportation emissions, as it is the major source contributing to greenhouse gas emissions (GHGs) and air pollution. However, the increasing travel demand due to the rise of population and economy makes the task challenging. Mathematically, road transportation emissions can be minimized in the manner of reducing total vehicle miles traveled (VMT) and lowering vehicle emission rate. Many strategies have been proven viable for achieving transportation sustainability. For example, the total VMT can be reduced by switching low-occupancy transportation modes (i.e., driving alone) to high-occupancy transportation modes (i.e., public transit, ridesharing). The development of alternative-fuel …

Peromyscus Maniculatus Bairdii And Peromyscus Maniculatus Sonoriensis Polymorphisms, Matthew Dixon Lucius

Theses and Dissertations

Sequencing technology has advanced greatly over the past couple of decades. This has led to many studies developing hypotheses based on genomic data. This requires many genomic studies to have up-to-date information on the species’ or subject’s genome being investigated. If a study does not have accurate or up-to-date background information, then they cannot fully develop their theories that are being established. In this study, I utilize outbred Peromyscus maniculatus, deer mice that are genetically diverse, to record the polymorphisms that are found throughout the Peromyscus maniculatus genome. I first explore the differences between the polymorphisms found in Peromyscus …

Too Feminine For Execution?: Gender Stereotypes And The Media’S Portrayal Of Women Sentenced To Death, Kelsey M. Collins

Theses and Dissertations

Traditional gender norms prescribing women as more nurturing and less aggressive than men have led to both the reluctance to view women as capable of violence, as well as a greater willingness to execute men than women in the United States. To make sense of the instances where women are sentenced to death, the media often pathologizes and/or demonizes them. Scholars have found that demonizing and dehumanizing those executed is a necessity to the implementation of capital punishment, both in cases of male and female defendants. To better understand how the news media have framed the gender and racial narratives …

Genomic Analysis Workflows To Identify Mutational Signatures And Structural Variations In Ovcar8 Cells And Rad51d-Deficient Mouse Embryonic Fibroblasts, Manli Yang

Theses and Dissertations

Specific genomic profiles associated with exposure to DNA damaging agents have been identified in cancer related genes, revealing that mutational patterns can be carcinogen- specific. However, there have been limited efforts to demonstrate similar clear relationships for endogenous mutational processes. One endogenous source of mutations is contamination of the deoxynucleotide pool with damaged bases that, if incorporated into DNA, cause mutations.

The Catalog of Somatic Mutations In Cancer (COSMIC) represents an international effort to characterize mutations in cancer. A mutational signature is the pattern of mutations generated by a mutational process. Each mutational process contains two parts: DNA damage and …

Decellularization Strategies Of Naturally Derived Biomaterials For Tissue Engineering Applications, Julia Elizabeth Hohn

Theses and Dissertations

In 2017, over 3.5 million peripheral vascular surgeries were performed worldwide with over 400,000 vascular repair or replacement surgeries being performed in the United States each year alone. As the number of vascular repair surgeries, including both coronary and peripheral bypass grafting procedures, continues to increase each year, these statistics indicate an urgent need for more effective and readily available replacement materials. Regenerative medicine and tissue engineering (TE) approaches, including the design, fabrication, and validation of suitable biomaterials in vitro that direct the repair and regeneration of damaged tissues, have been proposed to alleviate this problem. While advanced biomaterials have …

Inspiring The Imagination, Nathan Terracio

Theses and Dissertations

As someone who has been a life-long audience member and who has worked in over a hundred different theatres on countless different productions over the course of my professional career, I have always been fascinated by the process of creating art out of thin air. I have watched artists undergo careful planning only to have that work thrown out during the rehearsal or technical process, or even sometimes during the last preview performance. I have watched moments unfold on stage at the last minute with seemingly no planning or effort. I have seen the reactions of audiences to moments that …

There’S Action In Silence: An Action Research Study On The Impacts Of Diverse Narratives In An Advanced Placement United States Government Class, Ashley Kristen Wright

Theses and Dissertations

In this action research study, I facilitated and evaluated student exposure to politically, socially, and economically diverse source material within my Advanced Placement United States Government classroom, seeking to resolve students’ apparent disconnect from experiences that differ from their own, which had made connections to topics like civil rights challenging to grasp. Because the supplemental material I had chosen for my government classes failed to provide opposing narratives for my students to make these connections, this study arose as a way to research and ultimately correct this problem from within my government classroom.

Over the course of a semester, I …

Digital Twins In Advanced Manufacturing To Enhance Manufacturing Efficiency, Max Kirkpatrick

Theses and Dissertations

Digital Twins of manufacturing systems are an emerging tool for improvement, optimization, and monitoring of physical manufacturing systems. The idea of representing physical systems with digital depictions has been prevalent since the early days of Computer Aided Design (CAD), but recently the concept of a Digital Twin has been expanded to encapsulate more than just a digital model of a design. Instead, the Digital Twin offers a unique, comprehensive, and real-time toolset for analysis and improvement of physical systems. These tools can be used to improve system efficiency, perform “what-if” analyses, virtually commission manufacturing equipment, analyze system performance in real …
