An Scir Model Of Meningococcal Meningitis, Kalimah Vereen

Theses and Dissertations

A model for meningitis is developed by adding a class of carriers to the basic SIR model. This model is used to analyze the impact a vaccination program can have on the health of the population of epidemic prone countries. Analysis of the model shows the local stability of the disease free equilibrium, the existence of an endemic equilibrium and computation of the reproduction number, ℜ0 . Using a MATLAB program we simulate a time course of the model using parameters gathered from the World Health Organization. The numerical solution demonstrates that our reproduction number was correct. We thenconcluded that …

Looking For Ways To Ruin A Perfectly Good Day: Masculinity In Bash: The Latter-Day Plays By Neil Labute, Daniel F. Devlin

Theses and Dissertations

Neil LaBute is one of the most prolific and challenging playwrights in America today. My thesis will explore his work bash: the latter-day plays through the frame of the performance and use of masculinity by his characters, and will create a vocabulary through which the remainder of LaBute's works can be studied, both in terms of academic scholarship and the practical application of that scholarship to the process of theatrical creation.

Enzymology And Molecular Biology Of Bile Acid 7alpha- And 7beta- Dehydroxylation By The Intestinal Bacteria Clostridium Scindens And Clostridium Hylemonae, Jason Michael Ridlon

Theses and Dissertations

The collective microbial genomes within our gut(microbiome) represent a powerful metabolic force, leading many authors to call our GI flora an "organ within an organ", and the metagenomic sequencing of our microbiome, "the second human genome project". Bile acids, endogenously produced by the host liver, represent both a strong selective pressure for potential colonizers, aswell as substrates for microbial metabolism. Indeed, microbes have evolved enzymes to deconjugate bile salts, epimerize bile acid hydroxyl groups, and 7alpha-dehydroxylateprimary bile acids. The products of microbial 7alpha-dehydroxylation, secondary bile acids, are suggested by numerous lines of evidence to be involved in promoting colon carcinogenesis. …

On Zeitgeist, James Sham

Theses and Dissertations

This thesis is an exploration into the possibilities and repercussions of articulating zeitgeist, that is, the spirit of our current age. The parameters and ramifications of such a project are, in this writing, analyzed in reference to the notion of historicity, and the narrative gaze that it perpetuates. The mechanism of canonization, and a discourse's capacity to be viral are examined.

A Key To All Mythologies, Theresa Frances Marchetta

Theses and Dissertations

Over the last two years(August 2006-June 2008) I have been engaged in landscape painting that takes an experimental approach to material. My use of acrylic, the plastic paint, combines landscape with distortion and artificiality. Plastic has lost the futuristic and hopeful appeal it had in the past but it might still be an apt material to employ for a truly American artwork.

Role Of The Small Terminase Subunit Encoded By Staphylococcus Aureus Pathogenicity Island Sapi1 In Formation Of Sapi1 Transducing Particles, Nicholas Paul Olivarez

Theses and Dissertations

Staphylococcus aureus pathogenicity island SaPI1 is a genomic element that is mobilized and transduced at high frequency by helper phage 80α. SaPI1 encodes a small terminase protein that belongs to the phage small terminase subunit family. The presence of SaPI1-encoded small terminase suggests that it plays a role in SaPI1-specific packaging into transducing particles by complexing with the 80α large terminase subunit and redirecting recognition to a pac site on SaPI1 DNA from 80α DNA. The effects of deleting the small terminase genes in SaPI1 and in a prophage copy of 80α are consistent with this hypothesis. Induction of the …

Funnel Vision, David Grainger

Theses and Dissertations

This paper will talk about the videos and sculptural installation in my thesis exhibition. Shooting videos outside of the studio developed into a project overarching any individual video or its particular signs. Thus, this paper will focus on the video project with examples that follow a timeline of development, rather than the actual 6 videos on display in the exhibit. The two-part sculpture "Deer in the Headlights" is created in the context of these videos, and coexists with them in a specific architectural space. This space, as well as the clichéd meaning of the deer's gaze, have a relation to …

Over The Line: John Edward Lawler And Fbi, Gregory C. Hershey

Theses and Dissertations

The FBI is the most recognized law enforcement entity in the world. During its nearly 100-year history, the Bureau has been involved in many controversies, most as a result of straying from its stated mission to investigate violations of federal law. This survey is based on personal papers of the former head of the Richmond Bureau, John Edward Lawler. Fortunately for historians, these files, many of which exist nowhere else in the agency's archives, open a window into the operational methods and investigative techniques of FBI agents. An examination of John Lawler's career provides insight into the conduct of field …

Beyond The Early Adopters: Examining The Potential For Car-Sharing In Richmond, Virginia, Steven P. Spears

Theses and Dissertations

Car-sharing is a membership-based mobility service that offers short-term vehicle rentals. Studies have shown that car-sharing can increase transportation sustainability by encouraging the use of public transit and reducing vehicle miles traveled. This thesis examines the potential for car-sharing in Richmond, Virginia through an attitude-based qualitative pilot study. Using the theory of planned behavior as a framework, urban and suburban residents were asked questions that measured car-sharing intention strength, mode choice habit, and life change effects. The study found that even among those with positive attitudes toward car-sharing, existing habits, lack of adequate commuting alternatives and the needs of non-driving …

Mechanical Abrasion And Electroporation In The Transformation Of Intact Pleurotus Ostreatus Hyphæ And Nutrient-Dependant Resistance To Hygromycin B, Alexander Cordesman

Theses and Dissertations

ABSTRACT 1: Abrasive treatment and subsequent electroporation of the basidiomycete Pleurotus ostreatus in a hypertonic buffer was investigated as a potential method of transforming of intact hyphæ. Mycelia, which are not capable of being transformed via electroporation due to interference by the cell wall, were abraded in an attempt to mechanically degrade the cell wall prior to electroporation. An electroporation field strength of 12,500 V/cm for 500 μs to 1.25 ms was found to be optimal based upon mortality effects. A 32 μm carborundum abrasive was initially evaluated but was quickly found to be inappropriately large so a corundum abrasive …

The Role Of Secreted Phosphoprotein-24 In Osteoblast Differentiation And Matrix Mineralization, Samuel Ramage

Theses and Dissertations

Secreted Phosphoprotein-24 (Spp24) was initially isolated and characterized as a component of bovine cortical bone matrix. Subsequent characterization has shown it is multiply phosphorylated and homologous to cystatin and TGF-β receptor type II. Spp24 is a minor component of the serum fetuin mineral complex that binds calcium-phosphate minerals and prevents their deposition. The TGF-β receptor homology domain binds BMP-2 weakly in vitro and enhances BMP-2’s osteogenic effects in vivo. The ability of Spp24 to affect BMP activity suggests an important role for Spp24 as a native, bioactive componentof bone that regulates bone development.

Spp24 was highly up-regulated in rat cortical …
