Decomposition Of Modules And Tensor Products Over Principal Subalgebras Of Truncated Polynomial Rings, Kevin Steine Jr. Harris

Mathematics Dissertations - Archive

The topic of my dissertation is to investigate the behavior of modules and tensor products over a truncated polynomial ring with prime characteristic. This investigation utilizes principal subalgebras of the truncated polynomial ring as the main tool for studying these objects. Then, we investigate if these modules and their tensor products have a similar behavior when viewed over more general truncated polynomial rings. In particular, we aim to investigate the behavior of these objects when we replace principal subalgebras over a field with prime characteristic by hypersurfaces over a field with no characteristic restriction.

Signatures Of Genome Evolution In Two Divergent Lizard Species From Texas, Jose A. Maldonado

Biology Dissertations - Archive

The continual reduction of the cost of high-throughput sequencing is now making it feasible to sequence large genomic and transcriptomic datasets for non-model organisms. Many of these under study non-model organisms have no available molecular data available. Yet, many of these organisms are of interest for their usefulness in addressing long-standing unanswered questions in the field of evolutionary biology or of conservational concern and need immediate intervention. Now we can quickly generate large datasets for these organisms, and here we generate two large datasets for lizards that are both of in interest in the genus Holbrookia and Aspidoscelis. In chapter …

Elucidating The Molecular Genetic Basis Of Behaviors Related To The Loser Effect, Marquerite Alizabeth Herzog

Biology Dissertations - Archive

Across the animal kingdom, when individuals experience social defeat (losing an aggressive conflict with a conspecific), it elicits stereotypical loser behavior such as isolation or submissiveness. In many species, social defeat is a precursor to the "loser effect" (LE), the propensity for individuals who lose a contest to lose subsequent competitions. Experiments in rodent systems reveal physiological consequences of social defeat and loser behaviors, but underlying genetic mechanisms of the LE remain elusive. Furthermore, of the recent studies investigating gene expression changes associated with social defeat, there is little focus on the recovery of LE, wherein some animals naturally exit …

Self-Assembling Peptides: From Fundamental Design To Therapeutic Applications, Weike Chen

Chemistry & Biochemistry Dissertations - Archive

Supramolecular peptide-based biomaterials have attracted much attention from researchers in various science and engineering fields because of the ease of synthesis and precise control over structures and physicochemical properties on multiple length levels. Self-assembled peptides have shown great potential as functional biomaterials for both diagnosis and treatment of various diseases. In Chapter 1, I will introduce several self-assembled peptide systems in terms of molecular design, structure characterization, and their biological applications. In particular, I will discuss new peptide self-assemblies with trigger-responsive properties for targeted molecular imaging and therapy. In Chapter 2, I will focus on peptide self-assembly that can target …

Microbial Diversity And Immunogenetics Of Whiptail Lizards (Aspidoscelis), Kathleen Currie

Biology Dissertations - Archive

Whiptail lizards of the genus Aspidoscelis are a complex of both sexual and asexual species with distributions in the United States, Mexico, and Central America. The parthenogenetic lineages arose through hybridization events between divergent sexual species; further backcrossing of the diploid parthenogens to the parentals is possible, and even hybridization with a third species produce triploid lineages. Here, we leverage the unique biology of whiptail lizards to evaluate and compare gut microbial communities between reproductive modes, investigate whether host genetic variation correlates with microbial diversity, and characterize MHC class II beta genes.

Identifying Loss, Animating Melancholy: Asian-American Narratives In Avatar: The Last Airbender, Spirited Away, And Bao, Jered Connery Mabaquiao

English Theses - Archive

Animated film provides a complex illustration of the creativity behind constructing narratives. This thesis aims to explore the way that racial and cultural identity are displayed within animated film. The purpose of this thesis will be paying close attention to the intersections of psychoanalytic theories of loss that are placed on a spectrum with terms such as trauma, mourning and melancholia all within the scope of racial identification. These terms will be worked through from texts from Sigmund Freud and Jacques Lacan as well as works that expand on these notions. These psychoanalytic texts will be applied to Nickelodeon's “Avatar: …

Nuclear war would produce dire global consequences for humans and our environment. We simulated climate impacts of US-Russia and India-Pakistan nuclear wars in an Earth System Model, here, we report on the ocean impacts. Like volcanic eruptions and large forest fires, firestorms from nuclear war would transport light-blocking aerosols to the stratosphere, resulting in global cooling. The ocean responds over two timescales: a rapid cooling event and a long recovery, indicating a hysteresis response of the ocean to global cooling. Surface cooling drives sea ice expansion, enhanced meridional overturning, and intensified ocean vertical mixing that is expanded, deeper, and longer …

Global Food Insecurity And Famine From Reduced Crop, Marine Fishery And Livestock Production Due To Climate Disruption From Nuclear War Soot Injection, Lili Xia, Alan Robock, Kim Scherrer, Cheryl S. Harrison, Benjamin Leon Bodirsky, Isabelle Weindl, Jonas Jägermeyr, Charles G. Bardeen, Owen B. Toon, Ryan Heneghan

Faculty Publications

Atmospheric soot loadings from nuclear weapon detonation would cause disruptions to the Earth’s climate, limiting terrestrial and aquatic food production. Here, we use climate, crop and fishery models to estimate the impacts arising from six scenarios of stratospheric soot injection, predicting the total food calories available in each nation post-war after stored food is consumed. In quantifying impacts away from target areas, we demonstrate that soot injections larger than 5 Tg would lead to mass food shortages, and livestock and aquatic food production would be unable to compensate for reduced crop output, in almost all countries. Adaptation measures such as …

Numerical Experiments Of Temperature Mixing And Post-Storm Re-Stratification Over The Louisiana Shelf During Hurricane Katrina (2005), Mohammad Nabi Allahdadi, Chunyan Li, Nazanin Chaichitehrani

Faculty Publications

Studying mixing and re-stratification during and after hurricanes have important implications for the simulation of circulation and bio-geochemical processes in oceanic and shelf waters. Numerical experiments using FVCOM on an unstructured computational mesh were implemented to study the direct effect of hurricane winds on the mixing and temperature redistribution of the stratified Louisiana shelf during Hurricane Katrina (2005), as well as the post-storm re-stratification timescale. The model was forced by Katrina’s wind stress obtained from a combination of H-Wind database and NCEP model. The climatological profiles of temperature and salinity for August (the month in which Katrina occurred) from the …

The physicochemical changes during the storage of high protein powders, such as skim milk powder (SMP), nonfat dry milk (NDM), and milk protein concentrates (MPC), can result in a variation in the functional properties of the powders. The objective of this study was to evaluate the effects of the storage of various milk powders (SMP, NDM, MPC40, and MPC70) on their functional properties. Three different lots of the powders were collected from US manufacturers and were analyzed for functional properties after 3, 9, and 15 months of storage at 25 °C. Additionally, this study also evaluated the effects of seasonal …

Artificial Operators: Function And Use In English, Emily Ae Williams

Linguistics & TESOL Dissertations - Archive

This dissertation provides a descriptive account of the use of ‘artificial operators’ on Reddit. I adopt the term artificial operators to refer to written symbols (e.g., #, ™, ©, ®) with overlapping linguistic and metadiscursive properties that are leveraged for a pragmatic effect (e.g., I love her even though she’s problematic™). I employ a mixed-methods approach, using a combination of corpus, experimental, and machine learning methods. Using a 1.2 billion word diachronic corpus of comments from the popular forum website, Reddit, I demonstrate that these operators are used in a small percentage of Reddit communities. Operator usage is therefore often …

Prosocial Antitrust, Amelia Miazad

UC Law Journal

Antitrust law is at the center of today’s public debate. It has even emerged as a rare unifying force, with bipartisan promises to combat the concentration of economic power. Meanwhile, the business community is grappling with mounting systematic risks arising from climate change, income inequality, and the COVID-19 pandemic. Unexpectedly, the largest asset managers in the world find themselves on the front lines of these battles. Due to the rise of index investing, these “universal owners” manage portfolios that are so large and diversified, their holdings mirror the entire economy. Their diversification protects them against idiosyncratic risk, but greatly exposes …

Does One Size Fit All? Why Our Genes Show The Need For Tailor-Made Solutions, Jack Haisman

UC Law Journal

Since the human genome was first sequenced in 2003, millions of consumers and medical professionals have swarmed the field of medical genetics, seeking to peer into the crystal ball and see what their own, or their patients’, futures may hold. Also rushing in are direct-to-consumer genetic testing companies like 23andMe and AncestryDNA, which can circumvent medical privacy laws by offering genetic testing without a medical provider.

Medical privacy regulations, such as the Health Information Portability and Accountability Act of 1996 (HIPAA), the Genetic Information Discrimination Act of 2008 (GINA), and those promulgated by the Federal Trade Commission, do not regulate …

2022 Resident Scholar Reflection: Liz Hutter, Liz Hutter

Marian Fellowships and Other Sponsored Research in the Marian Library

Liz Hutter, an assistant professor of English at the University of Dayton, received the Marian Library Resident Scholar Fellowship for the project “Reading, Writing, and Seeing Health and Disability in Community at Lourdes Sanctuary.”

An account from the writer Flannery O’Connor, whose cousin suggested a pilgrimage to Lourdes as a healing intervention for a chronic illness, prompted Hutter’s interest in pursuing what she sees as a binary logic often associated with Lourdes, the shrine commemorating the 1858 apparitions of the Virgin Mary to Bernadette Soubirous.

O’Connor made a distinction clear to her cousin: “I am going as a pilgrim, not …

Sarracenia Pitcher Plant-Associated Microbial Communities Differ Primarily By Host Species Across A Longitudinal Gradient, Jacob A. Heil, Charles J. Wolock, Naomi E. Pierce, Anne Pringle, Leonora S. Bittleston

Biology Faculty Publications and Presentations

Plant-associated microbial communities can profoundly affect plant health and success, and research is still uncovering factors driving the assembly of these communities. Here, we examine how geography versus host species affects microbial community structure and differential abundances of individual taxa. We use metabarcoding to characterize the bacteria and eukaryotes associated with five, often co-occurring species of Sarracenia pitcher plants (Sarraceniaceae) and three natural hybrids along the longitudinal gradient of the U.S. Gulf Coast, as well as samples from S. purpurea in Massachusetts. To tease apart the effects of geography versus host species, we focus first on sites with co-occurring …

The Nonprofit Sector And Cannabis Industry: Creating Cross-Sector Partnerships For A Sustainable And Equitable Future In New Jersey And Beyond, Abigail Rose Perl

Master's Projects and Capstones

The Cannabis industry is currently rolling out a legal industry, medical and recreational, across the United States. While some state legislators are celebrating legalization as a success alongside Multi-State Operators (MSOs), Legacy operators, or those involved in the Cannabis industry prior to legalization, have yet to bask in the benefits of legalizations as their corporate successors. Even more so, those who have faced adversities or have been criminalized by Cannabis have yet to see the benefit of Cannabis than many MSOs do. While legislators try to reverse the wrongdoings of the War On Drugs set out by our own government, …

Department of Dermatology and Cutaneous Biology Faculty Papers

Lack of type VII collagen (C7) disrupts cellular proteostasis yet the mechanism remains undescribed. By studying the relationship between C7 and the extracellular matrix (ECM)-associated proteins thrombospondin-1 (TSP1), type XII collagen (C12) and tissue transglutaminase (TGM2) in primary human dermal fibroblasts from multiple donors with or without the genetic disease recessive dystrophic epidermolysis bullosa (RDEB) (n=31), we demonstrate that secretion of each of these proteins is increased in the presence of C7. In dermal fibroblasts isolated from patients with RDEB, where C7 is absent or defective, association with the COPII outer coat protein SEC31 and ultimately secretion of each of …

A Brief Acceptance And Commitment Therapy Protocol For Alcohol Withdrawal Symptoms: A Randomized Controlled Trial For Inpatient Detoxification Patients, Taylor R. Weststrate

Dissertations

Alcohol detoxification inevitability involves physical and emotional discomfort. Common withdrawal symptoms include experiences of nausea, muscle pain, stomach and headaches, shakiness, restlessness, anxiety, and agitation. Rarer, but more severe, withdrawal symptoms can include hallucinations, seizures, and delirium tremens. Pharmacologic treatment of withdrawal symptoms is the primary, and often only, approach to intervention. The current study examined the incremental efficacy of adding a psychotherapeutic program based in Acceptance and Commitment Therapy (ACT) for individuals struggling with withdrawal during alcohol detoxification in a residential rehabilitation center. This study compared the standard of care, medication management, which was treatment as usual (TAU) at …

This study focuses on addressing this problem by exploring the academic and social experiences of African American college students who persisted at a regional predominantly White institution (PWI) in the Midwest and secure information that can be used to improve their graduation rates.

To address this issue, this study is designed to explore initiatives and practices that …

Studying The Synthesis Of 196Hg At Astrophysically Relevant Energies Through The Measurement Of Capture Reaction Cross-Sections Of (P, Γ) (P, N) And (P, Α) Reactions, Khushi Bhatt

Dissertations

Understanding the origin of all the chemical elements is an important question for the nuclear-astrophysics community. There are many unanswered questions like: What astrophysical events are responsible for the synthesis of what particular chemical elements? How many different elements were made in total? What is the abundance of each synthesized element? etc. Currently, scientists are largely depending upon theory and simulations to define nuclear and astrophysical reaction. This makes it critical to have accurate experimental nuclear physics data to input in astrophysical theoretical models. However, out of more than 20000 reactions involved in these calculations, only a very few are …

Peridynamic Modeling Of Crack Propagation In Brittle Materials With Electromechanical Coupling, Semsi Coskun

Dissertations

The bond-based peridynamics (BB-PD) is a widely used peridynamic model in the literature. Despite Poisson's ratio restriction, it still serves as a powerful tool to solve challenging engineering problems with a relatively cheap computational cost. Consider the Poisson ratio of the material does not deviate from the ones that BB-PD can model. In that case, it becomes advantageous to use the BB-PD compared to other PD models in terms of computational cost and simplicity. However, the BB-PD suffers from the so-called surface or skin effect where the material response at boundaries becomes softer than the bulk material points. As a …

Ultra-Compact Hybrid Silicon: Chalcogenide Waveguide Temperature Sensor, Bahareh Badamchi, Wei-Che Hsu, Al-Amin Ahmed Simon, Zong Yin Chi, Jacob Manzi, Maria Mitkova, Alan X. Wang, Harish Subbaraman

Electrical and Computer Engineering Faculty Publications and Presentations

We demonstrate a real-time, reusable, and reversible integrated optical sensor for temperature monitoring within harsh environments. The sensor architecture combines the phase change property of chalcogenide glasses (ChG) with the high-density integration advantages of high index silicon waveguides. To demonstrate sensor feasibility, ChG composition Ge₄₀S₆₀, which is characterized by a sharp phase transition from amorphous to crystalline phase around 415 °C, is deposited over a 50 µm section of a single mode optical waveguide. The phase transition changes the behavior of Ge₄₀S₆₀ from a low loss to high loss material, thus significantly …

Prevalence And Factors Associated With Undernutrition Among Children With Congenital Heart Disease At Three Tertiary Hospitals In Nairobi, Kenya., Shamsa Yahya

Master of Medicine in Paediatrics and Child Health

Background: Congenital heart disease (CHD) is the commonest birth defect. Children with CHD have a high burden of undernutrition and its consequences. Some of the factors that are associated with undernutrition in children with CHD include the type and complexity of the heart defect, associated pulmonary hypertension, late diagnosis, timing of surgical correction, low socioeconomic status, lack of adequate nutritional support, associated genetic conditions and the presence of other clinical comorbidities. Justification: Although these factors are well defined, they vary geographically in their distribution and extent to which they influence the level of undernutrition. This limits the extrapolation of findings …
