My Child And My Life: Sacrificial Obligation And Chaucer, Gary Scott Montano Jan 2011

My Child And My Life: Sacrificial Obligation And Chaucer, Gary Scott Montano

English Dissertations

Medieval literature demonstrates that Christians of that era took their Bible seriously, particularly the Old Testament account of Abraham's sacrifice of Isaac. For them, the story was both fascinating and perplexing. Not only was Abraham one of the most revered figures, but he was also one of the most frustrating. He was admired for his ability to obey God's directive to sacrifice Isaac, but because he does so without displaying an ounce of emotion, that admiration is often coupled with irritation. How could a father as loving as Abraham remain expressionless and emotionless as he raised the knife to kill …

No Longer Estranged: Women, Science, Science Fiction, Christy Tidwell Jan 2011

No Longer Estranged: Women, Science, Science Fiction, Christy Tidwell

English Dissertations

Feminist science fiction (SF) and feminist science studies share common concerns--the gendered perception of science and women's place in the sciences among them--but the two fields are rarely considered together. This failure to connect the two fields may be explained in part by the ongoing divide between the sciences and the humanities; it may be further exacerbated by the ghettoization of SF within literary studies. I gather together feminist SF texts, literary theories of feminist SF, and feminist science studies in order to add to the scholarship of each individual field as well as make a case for the value …

Micromotion And Scarring Do Not Contribute To Failure Of Regenerative Peripheral Neural Interfacing, Nivedita Khobragade Jan 2011

Micromotion And Scarring Do Not Contribute To Failure Of Regenerative Peripheral Neural Interfacing, Nivedita Khobragade

Bioengineering Theses

Neuroprosthetics facilitate amputees with motor function restoration by interfacing nervous system with artificial limb and enabling control of the prosthetic device by volitional thought. Though such neurointerfacing provides dexterity nearly mimicking natural limb agility, the clinical viability of such prosthetics is limited by the lack of long-term reliability. In central nervous system, these implants fail due to foreign body reaction and glial scar formation around the implant. The cause of decrease in active sites of interfacing in peripheral nervous system, which is less invasive than central nervous system implantation, has not been established. Recently an open architecture, regenerative peripheral neural …

Use Of Steel Fiber Reinforced Concrete In Structural Members With Highly Complex Stress Fields, Tarun Pareek Jan 2011

Use Of Steel Fiber Reinforced Concrete In Structural Members With Highly Complex Stress Fields, Tarun Pareek

Civil Engineering Theses

Reinforced concrete (RC) members with significant geometric discontinuities and complex stress distributions under loading require considerable analyses and usually complicated reinforcement detailing. RC members with large openings are one of the examples. These large openings may interrupt the load transfer by direct concrete struts and cause substantial decrease in strength and unpredictable failure modes. The reinforcement detailing of these concrete members based on strut-and-tie models (STMs) is generally complicated and very often, these models cannot predict the failure mechanism due to localized damages. The actual stress fields in such members are typically very different from that predicated by STMs, as …
