Mechanical Strength Assessment Of Pharmaceutical Compacts With Refractive Index Measurements From Terahertz Time Of Flight Spectroscopy, Shikhar Mohan

Electronic Theses and Dissertations

The mechanical strength of pharmaceutical compacts is often considered as a critical quality attribute for roller and tablet compaction processes. Most traditional mechanical strength tests are destructive, thus, preventing further material testing. This thesis expands on the application of terahertz time of flight spectroscopy (THz-TOF) as a nondestructive technique for assessing mechanical strength. This technique is able to extract the refractive index; which is a function of porosity and crystallinity of the solid. Thus, it was hypothesized that refractive index measurements from terahertz time of flight spectroscopy are directly related to porosity; therefore, these nondestructive measurements are able to correlate …

Subjects Of Economy: Social Documentary Poetics And Contemporary Poetry Of Work, Michelle B. Gaffey

Electronic Theses and Dissertations

Although the term “documentary” originated in film and photography studies, it has been used to describe a range of compositional and research strategies in discussions of twentieth and twenty-first century poetry as well. A study of such documentary poetics, however, requires us to distinguish between documentary poetics in general and social documentary poetics in particular. To illustrate this distinction, I discuss five contemporary books of poetry and photographs: C.D. Wright’s and Deborah Luster’s One Big Self: Prisoners of Louisiana, Cynthia Hogue’s and Rebecca Ross’s When the Water Came: Evacuees of Hurricane Katrina, Chris Llewellyn’s Fragments from the Fire: …

“That Those Hearing Or Reading Might Strive To Imitate”: Donative Intent, Positive Triangular Mimetic Desire, And The Portrayal Of The Mediator-Divine (Non)Object Relationship In Richard Rolle, Julian Of Norwich, And Richard Crashaw, Steven Geitgey

Electronic Theses and Dissertations

Mystical texts often present themselves as possessing a “donative” intent, in which the writer aims to share the significance of their own experience. This dissertation will show how a consideration of donative intent and its textual results can enrich the study of medieval and early-modern mystical writings, approaching them from the broad concept of triangular mimetic desire in conjunction with other theoretical insights in order to examine the methods through which writers seek to portray their mediator-object relationship with God and inspire reading subjects’ mimetic desire.

I will elucidate Richard Rolle’s portrayal of his mediatorial purpose and unique experiences, and …

Accurate Quantitation Of Hexavalent Chromium For Reference Standard Certification And Quality Control Testing Using Speciated Isotope Dilution Mass Spectrometry, James E. Henderson

Electronic Theses and Dissertations

The ability to perform accurate, repeatable, and defensible elemental and molecular speciated analysis is immensely significant for measurements that support human health, environmental science, and industry. This is especially true since trivalent chromium [Cr(III)] is necessary for proper nutrition, while hexavalent chromium [Cr(VI)] is extremely toxic, genotoxic, and carcinogenic. The main challenges associated with speciated analysis are related to reactive species that are continuously transformed or converted to other species during sample processing. Accurate determination of Cr(III) and Cr(VI) species require a method that is capable of monitoring and correcting for interconversion, bias, and instrumental error.
