Theorizing Mathematical Proof As Becoming: A Deleuzio-Guattarian Investigation, Joshua P. Case

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this dissertation, I utilize the post-structural philosophy of Gilles Deleuze and Félix Guattari as a lens for investigating the proof process. Deleuze and Guattari were both post- structural philosophers who, like many in this tradition, troubled traditional notions related to stable identities, meaning, language, and mathematics. For Deleuze, sense and meaning is not the result of a sterile, transcendent effect or condition that is associated with propositions and states of affairs. Rather, it is the result of a material production that emerges from the world and that has independence from language and the mind. I apply this framework to …

Role Of Β4b-Tubulin (Tubb4b) In The Sensory System And Spermatogenesis, Urikhan Sanzhaeva

Graduate Theses, Dissertations, and Problem Reports (ETD)

Microtubules are ubiquitous cytoskeletal filaments essential in the function of eukaryotic cells. These polymers, comprised of αβ-tubulin heterodimers, are critical for cell division, intracellular transport, and formation of the axonemes of cilia and flagella. This functional diversity of microtubules is attributed to the incorporation of various α- and β-tubulin isotypes encoded by different genes. Indeed, mutations in human tubulin genes have been linked to various tissue-specific diseases, suggesting a unique function for each tubulin isotype. Mutations in the β4B-tubulin gene (TUBB4B) are associated with sensorineural hearing loss, Leber Congenital Amaurosis (LCA), a severe childhood blindness, and primary ciliary dyskinesia …
