Emerging Chromatin Regulators In Response To Heavy Metal Exposure, Wesley Saintilnord

Theses and Dissertations--Molecular and Cellular Biochemistry

Environmental exposure to heavy metals poses significant threats to human health as they are associated with various developmental and chronic pathologies such as reproductive defects and cancers. Despite their profound risks, a comprehensive understanding of their disease-causing mechanisms is lacking. Most studies point to reactive oxygen species-induced DNA damage; however, their mutagenic potential is relatively weak suggesting the involvement of alternative mechanisms. One important, yet underexplored mechanism, is their ability to rewire the epigenome via DNA methylation and histone variant incorporation, leading to aberrant gene regulatory networks.

This study investigates the epigenetic mechanisms targeted by two ubiquitous heavy metals with …

Effects Of Mindfulness Training On Prosocial Responses In Intergroup Relations: A Pilot Randomized Controlled Trial, Denise Yiran Zheng

Theses and Dissertations

Based on social identity theory and intergroup emotions theory, individuals feel for and act toward others based on their group-based social identities. Recent research shows that mindfulness can enhance prosocial responses toward others across group divides. The current research examined the effects of mindfulness training on prosocial behavior in intergroup relations where such behavior is difficult (e.g., with marginalized or devalued social groups). The study also examined potential mechanisms, namely state empathic concern and appraisal, that may explain how mindfulness increases prosocial behavior toward outgroups. This study compared the effects of a 2-week mindfulness training to a matched coping training …

Symmetry Analysis Of The Canonical Connection On Lie Groups:Co-Dimension Two Abelian Nilradical With Abelian And Non Abelian Complement, Nouf Alrubea Almutiben

Theses and Dissertations

We consider the symmetry algebra of the geodesic equations of the canonical
connection on a Lie groups. We mainly consider the solvable indecomposable four,
five and six-dimensional Lie algebras with co-dimension two abelian nilradical, that
have an abelian and not abelian complement. In this particular case, we have only
one algebra in dimension four namely; A4,12 , and three algebras in dimension five
namely; A5,33, A5,34, and A5,35 In dimension six, based on the list of Lie algebras in
Turkowski’s list, there are nineteen such algebras namely; A6,1- A6,19 that have an
abelian complement, and there are eight algebras that …

Outcomes Of Anterior Crossbite Correction On Alveolar Bone Morphology In Patients With Cleft Lip And Palate, Katherine J. Hayes

Theses and Dissertations

Objective: To determine if patients with cleft lip and/or cleft palate (CLP) with dental correction of the anterior crossbite during growth display differences in alveolar bone thickness around the maxillary central incisors compared to patients without crossbite correction.

Methods: This retrospective study evaluated post-treatment cone beam computed tomography (CBCT) images of growing patients with CLP with anterior crossbites who underwent Phase I orthodontic treatment (n=32). CBCTs were sorted by whether the crossbite was corrected (n=16) or not corrected (n=16) during Phase I. Alveolar bone thickness was measured on the buccal and palatal aspects of the central incisors at 3 mm, …

Collaborative Robotic Finishing Platform For Metal Part Processing Towards Industry 5.0, Seyedhossein Hajargarbashi, Gabriel Côté, Jonathan Boisvert, Ramy Meziane, Chen Xu, Corentin Hubert, Sabrina Jocelyn, Clément Gosselin

Articles dans des actes de congrès

Manual finishing operations in aerospace and ground transportation industries are often associated with health-and-safety-related issues such as musculoskeletal disorders, productivity loss, and challenges in workforce renewal. This work presents an innovative automated solution to address these challenges, prioritizing the ease of implementation and affordability for small and midsize enterprises (SMEs). Our proposed solution is a collaborative robotic (cobotic) finishing platform designed to eliminate labor-intensive work while keeping human operators in the loop to manage unforeseen situations. This platform aims to eliminate health risks, enhance repeatability, improve product quality, and increase productivity. This paper describes the mechanical design of the platform, …

Advancing Clinical Bacterial Diagnosis: Gram-Stained Whole-Slide Image Classification With Attention-Based Deep Learning, Jack Mcmahon

Computer Science Senior Theses

We introduce a new method for the classification of Gram-stained WSIs. As a test for the diagnosis of blood infections, Gram stains are highly relevant to informing patient treatment. Rapid analysis of Gram stains has been shown to be positively associated with better clinical outcomes, indicating the need for better tools to aid in automatic Gram stain analysis. To date, this area of research has been underexplored, with previous studies relying on the manual patch-level annotation of WSIs to generate training data. This is the first application of a transformer-based model to Gram-stain WSI classification, an approach that is far …

An Exploratory Study Of Ombuds As Agents Of Change: From Observation To Action, Michael A. Wahlgren

Department of Conflict Resolution Studies Theses and Dissertations

This research focuses on identifying successful approaches used by university ombuds offices to enact change regarding dispute resolution options within their academic institute. The field of Ombuds has grown steadily in North America since the 1970s and is widely used by private industry, academia, and government organizations to deploy alternative dispute resolution techniques, an often cheaper and more successful means of conflict resolution compared to the traditional litigious approach. Identifying how ombuds approach promoting change requires understanding the dispute resolution system and the conditions that produce conflict. Based on interviews with 10 current university ombuds officers from a variety of …

The researcher used a structural narrative approach and thematic analysis, guided by the following research question: What are Black women’s experiences when they choose to wear their hair in its natural state as they seek career advancement in the federal government? The two major theories used in this study to elucidate participants’ experiences were structural violence and intersectionality. The following theories provided insight and context to intersectionality: …

A Case Study Analysis Of The Financial Structure Of Boko Haram In Nigeria, John O. Opara

Department of Conflict Resolution Studies Theses and Dissertations

This study examined the various techniques used by Boko Haram (BH) to source funds for its violent activities in Nigeria. The study also examined the reasons why the group maintains support from the locals and others despite the violence the group has caused in Nigeria. A case study qualitative research technique was selected by using Key Informant Interviews (KII) and relevant document review to gather data to address the central questions of why Boko Haram has support, and why it maintains a strong financial structure. Findings of the study revealed that Boko Haram has several sources of funding and support …

Decisional And Intrapersonal Conflicts Regarding Treatment Choice For Breast Cancer And The Lived Experiences Encountered During Treatment., Uchennamee Vital Durulawrence

Department of Conflict Resolution Studies Theses and Dissertations

Breast cancer is a widely recognized health concern, yet the concept of 'intrapersonalconflict' within the context of breast cancer treatment is relatively underexplored. While existing research predominantly addresses the impact of a breast cancer diagnosis on everyday life, there is limited investigation into the decisional and intrapersonal conflicts that women face during the course of their treatment. This qualitative study employs transcendental phenomenological analysis to examine these conflicts and the broader experiences of women as they navigate treatment decisions, lifestyle adjustments, and relational dynamics throughout their breast cancer journey. The study participants comprised 12 women aged between 21 and 80, …

Giving Voice To The Victims Of The Insurgency In Eastern Uganda In The Late 1980s And Early 1990s: A Phenomenological Research Study, Lawrence Egulu

Department of Conflict Resolution Studies Theses and Dissertations

After five years of protracted guerilla warfare, Uganda’s current President Yoweri Museveni capturedpower in January 1986, displacing the preceding regime that had been dominated by Northern politicians and Eastern Ugandans (army and police). Feeling humiliated, deprived, and out of government, several rebel insurgencies erupted, among which was the Uganda People’s Army in the Teso region. The experiences of the affected population at the hands of the army, rebels, and the Karamojong cattle raiders from the North East have remained largely unexplored, unheard, and undocumented outside of the region, and neither have how the victims made meaning of their conditions. The …
