Non-Western Rendition Of Ambient Rhetoric Of Khajuraho Monuments., Shiva Hari Mainaly Aug 2023

Non-Western Rendition Of Ambient Rhetoric Of Khajuraho Monuments., Shiva Hari Mainaly

Electronic Theses and Dissertations

This dissertation develops an ambient rhetoric: a living practice that is more disclosive than communicative, more entangled than intersectional, and more subtle than explicit and evidential. Rather than exploring the symbology, iconography, texture, and artistic integrity of Khajuraho monuments, I claim that Khajuraho monuments aim at convincing visitors with their persuadability and affectability inherent in their material bases, architectural panels, fractal design, allegorical cast, aura of attunement, and the environment in which the monument complex is nestled. Khajuraho groups of monuments in Central India, matchless in their monumentality, dynamic in their adjustment to the shifting socio-politico-cultural landscape in the world, …

Fbg Αc 389 – 402 Modulates Factor Xiii Crosslinking In The Fibrinogen Αc Region., Francis Dean Orlina Ablan

Electronic Theses and Dissertations

Fibrinogen (Fbg) is a coagulation protein critical for clot formation. Coagulation Factor XIII (FXIII) is a calcium-dependent transglutaminase that crosslinks reactive glutamines (Q) and lysines (K) between fibrin and other anti-fibrinolytic proteins. In the presence of Ca2+, FXIII could be activated non-proteolytically (FXIII-A°), or proteolytically by thrombin (FXIII-A*). Significant increases in clot stability and red blood cell retention are linked to FXIII activity in the fibrinogen αC region (Fbg Aα 221 – 610). This region contains several FXIII-reactive glutamines and lysines, as well as a binding site for FXIII-A* (Fbg αC 389 – 402) that includes a key …
