Cholesterol Mass Fingerprinting To Probe Cholesterol-Protein Interactions, Warren Lowther

Electronic Theses and Dissertations

Cryomicroscopy, crystallography and NMR have been considered the “gold standard” of structural biophysics for some time. Recent successes in using these techniques has provided us with a plethora of insight into the architecture of different macromolecules like channels, transporters, and other molecular machines. However, information is often limited to a single allosteric state with the macromolecule in a non-native environment. Additionally, these traditional methods tend to be expensive and labor-intensive, requiring samples that are concentrated and highly purified. Chemical crosslinking coupled with mass spectrometry (CX-MS) has emerged as the ideal accessory for the aforementioned structural tools. In order to address …

Computational Models Of Vocal Fold Lesions: Analysis Of Fluid-Structure Interaction, Manoela Rocha Neves

Electronic Theses and Dissertations

The biomechanical and aerodynamic behaviors of the vocal folds (VFs) during phonation are heavily influenced by their structural composition and pathological changes. These conditions can induce localized stiffening that disrupts vibratory symmetry and alters airflow resistance. Previous research has lacked the integration of VF lesions in computational simulations using anatomically accurate models, limiting the understanding of their effects in phonation and potential contribution to voice disorders. Addressing this gap, this thesis develops a fluid-structure interaction (FSI) model of a realistic two-layered VF structure with lesions, comparing airflow patterns, structural deformations, and vibration profiles in both healthy and diseased cases.

This delay in diagnosis hinders timely interventions and appropriate treatment, further contributing to the spread of resistant infections. As such, there …

A Raced Theology Of The Human Person: An Expanded Theological Anthropology, Cary W. Dabney

Electronic Theses and Dissertations

This dissertation focuses on race as a critical, yet largely unaddressed, topic in Catholic theological anthropology. In Catholic colleges and universities that are recognized as members of the Cardinal Newman Society, theological concerns about race are deemed irrelevant for theological education in the faith and are altogether absent from the theology of the human person. As a result, this collection of institutions treats race as a specialty within pastoral theology, one that is significant to groups, but not a part of the fundamental theology of the human person. This ‘un-raced’ theological anthropology results in the institution’s inability to respond effectively …

Communicative Harmonics: A Synchronization Of Minds, Manners, And Emotions As A Phenomenological Approach To Resonant Leadership, Victor J. Grigsby
