Enhancing Reductive Dechlorination Of Chlorinated Ethenes And Ethanes In A Natural Treatment System, Caroline Burda Jan 2009

Enhancing Reductive Dechlorination Of Chlorinated Ethenes And Ethanes In A Natural Treatment System, Caroline Burda

LSU Master's Theses

Chlorinated solvent contamination continues to plague sites around the world. In many cases, lower chlorinated daughter products build up and remain in ground waters and soils. A Bio-Filter/Phytobed (BFP) system has been developed to replace a traditional pump and treat technology currently operating at the ReSolve Superfund site in North Dartmouth, MA. Pilot scale testing at the facility displayed a significant acclimation period prior to microbial dechlorination, as well as delayed degradation of chlorinated ethanes. Microcosm studies suggest that acidic conditions, possibly created by the peat mixture used to construct the bio-filter, inhibited bacterial growth. The neutralization of trench pH …

Gas Transfer In Air-Lifts Used To Recirculate Aquaculture Systems, Ryan Anthony Hearn Jan 2009

Gas Transfer In Air-Lifts Used To Recirculate Aquaculture Systems, Ryan Anthony Hearn

LSU Master's Theses

The following studies were conducted to determine hydraulic, aeration, and degasification characteristics associated with various air-lift pumps. The first study presented data on a 20.3 cm air-lift used to support adult Yellowtail broodstock (Seriola lalandi) in an oligotrophic warmwater marine RAS (recirculating aquaculture system). Empirical relationships were used to estimate actual oxygen and carbon dioxide mass transfer rates (AOTR & ACTR) as the inlet oxygen or carbon dioxide concentrations were perturbed under lift heights of 30.5, 38.1, and 45.7 cm. Transfer rates, kg of constituent per day, were found to be dependent on air injection depth and volume, aqueous gas …

Prioritization Of Safety Countermeasures For The State Of Louisiana Using Fuzzy Inference Systems, Meisam Akbarzadeh Jan 2009

Prioritization Of Safety Countermeasures For The State Of Louisiana Using Fuzzy Inference Systems, Meisam Akbarzadeh

LSU Master's Theses

In this study a fuzzy inference system is proposed for prioritization of countermeasures aimed at improving safety in the state of Louisiana. Countermeasures are prioritized based on their collective performance on cost, expected crash reduction and the severity of the problem they address. These three decision parameters can have six permutations in terms of their relative importance in decision making. In order to make the prioritization procedure handier for decision makers, the inference system is capable of being run under all six possible cases. Current safety standards influence the importance attached to crash reduction performance and severity of the problem …

Public Opinion And The Katrina Disaster: Linking Support For Rebuilding And Perceptions Of Flood Victims In New Orleans, Vincenzo Pasquantonio

LSU Master's Theses

Public support for government assistance to the needy has long been the focus of scholarly attention. Some assert that the perceived race of recipients of such aid is the primary determinant influencing such support. Others cite that it is the degree of trust one has in government institutions while still others cite American notions of individualism and self-reliance versus collective responsibility. The present study analyzes public opinion regarding aid to the City of New Orleans and its inhabitants following Hurricane Katrina and the subsequent flooding of the city. Several important findings emerge from this analysis. First, it cannot be demonstrated …

Typewriters Typing Typist: A Performance History, Sarah Kathryn Jackson Jan 2009

Typewriters Typing Typist: A Performance History, Sarah Kathryn Jackson

LSU Master's Theses

This study contributes to the ongoing exploration of the multiple ways visual and material artifacts perform. I take a look at how typewriters or rather how two representations of typewriters perform. I focus on two different images of working women, each rendered in terms of a popular female stereotype of the period. I selected the images because they bookend a period of time in which typewriters emerged to the fore as an efficient tool of reproduction in the business world. In turn, two different perspectives on the relationship between the typist and her typewriter, woman and machine, are provided. The …

Your Land Is My Land: Exploring Land Policy In Tangerang, Indonesia Using Kingdon's Multiple Streams Model, Milla Budiarto Jan 2009

Your Land Is My Land: Exploring Land Policy In Tangerang, Indonesia Using Kingdon's Multiple Streams Model, Milla Budiarto

LSU Master's Theses

Indonesia is the world’s largest archipelagic country comprised of over 17, 000 islands with more than 300 ethnic groups and more than 250 different ethnic languages spoken. Due to its land mass size and multifaceted culture, land policy in this country has been ineffective and inadequate in addressing some of the land affairs. One of the indicators of effective land policy is land tenure security, where land dispute incidence is a function of it. Given that the government has very minimal guarantee for land tenure security in this nation, land disputes are inevitable and very common. By the end of …

The Plame Game: Framing A Political Scandal, Misty Dawn Albrecht Jan 2009

The Plame Game: Framing A Political Scandal, Misty Dawn Albrecht

LSU Master's Theses

The media play an important role in society. They interpret political events, actions, policies, and scandals in a manner that citizens can understand. The media use frames to assist in interpretations and descriptions. They may create their own frames or use frames supplied by the political elites. Frames can also lead to biased coverage when used to omit details or present someone in a favorable or unfavorable manner. This study examines the frames the media used during the coverage of President George W. Bush’s first political scandal, the “Plame Game.” On July 14, 2003, Robert Novak exposed the identity of …

Numerical Modeling Of Hemodynamics In The Thoracic Aorta And Alterations By Dacron Patch Treatment Of Aortic Coarctation, Ronak Jashwant Dholakia Jan 2009

Numerical Modeling Of Hemodynamics In The Thoracic Aorta And Alterations By Dacron Patch Treatment Of Aortic Coarctation, Ronak Jashwant Dholakia

Master's Theses (2009 -)

Coarctation of the aorta (CoA) is a major congenital heart disease, characterized by a severe stenosis of the proximal descending thoracic aorta. Traditionally, surgery has been the treatment of choice for CoA. Dacron patch aortoplasty gained increased popularity after its introduction in the mid-twentieth century due to its advantages over other surgical treatment methods available at the time. A major complication with Dacron patch aortoplasty has been the formation of late aneurysm with as much as 51% incidence reported in follow up studies. The change in aortic morphology and formation of aneurysms after Dacron patch surgery could lead to local …

Debord, Constant, And The Politics Of Situationist Urbanism, Brian Elliott Jan 2009

Debord, Constant, And The Politics Of Situationist Urbanism, Brian Elliott

Philosophy Faculty Publications and Presentations

In the first years of its existence between 1957 and 1960 the efforts of the radical collective the Situationist International (SI) centred on its program of "unitary urbanism." This program sought to challenge the functionalist character of hegemonic forms of urban planning through novel practices of urban experimentation and contestation. Situationist urbanism arose largely through the collaboration between Guy Debord and the Dutch avant-garde architect Constant. This article explores the political dimension of situationist urbanism and the tensions that led to Constant’s secession from the group in 1960. Through analysis of the affinities and divergences between urbanism in its modernist …

Noninvasive Measurement Of Aminolevulinic Acid-Induced Protoporphyrin Ix Fluorescence Allowing Detection Of Murine Glioma In Vivo, Summer L. Gibbs-Strauss, Julia A. O'Hara, P Jack Hoopes, Tayyaba Hasan, Brian W. Pogue

Dartmouth Scholarship

Aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) fluorescence is studied as a contrast agent for noninvasive detection of murine glioma, using the fluorescence-to-transmission ratio measured through the cranium. Signals measured prior to administration of ALA are very similar between control animals, 9L-GFP, and U251 tumor-bearing animals. However, 2 h after ALA administration, the PpIX signal from both tumor-bearing groups is significantly higher than the control group (9L-GFP group p-value=0.016, and U251 group p-value=0.004, relative to the control group). The variance in signal from the 9L-GFP group is much larger than either the control group or the U251 group, which is consistent …

Quantitative Imaging Of Scattering Changes Associated With Epithelial Proliferation, Necrosis And Fibrosis In Tumors Using Microsampling Reflectance Spectroscopy, Venkataramanan Krishnaswamy, P Jack Hoopes, Kimberley S. Samkoe, Julia A. O'Hara, Tayyaba Hasan, Brian W. Pogue

Dartmouth Scholarship

Highly localized reflectance measurements can be used to directly quantify scatter changes in tissues. We present a microsampling approach that is used to raster scan tumors to extract parameters believed to be related to the tissue ultrastructure. A confocal reflectance imager was developed to examine scatter changes across pathologically distinct regions within tumor tissues. Tissue sections from two murine tumors, AsPC-1 pancreas tumor and the Mat-LyLu Dunning prostate tumor, were imaged. After imaging, histopathology-guided region-of-interest studies of the images allowed analysis of the variations in scattering resulting from differences in tissue ultra-structure. On average, the median scatter power of tumor …

Finding Confucianism In Scientology: A Comparative Analysis, John Albert Kieffer Jan 2009

Finding Confucianism In Scientology: A Comparative Analysis, John Albert Kieffer

USF Tampa Graduate Theses and Dissertations

Scientology holds considerable interest for scholars of new religious movements. As such, this study aims to contribute new data and insight to ongoing theoretical work within this area of religious studies scholarship. Engaged in this inquiry are the similarities between Scientology, the new religious movement founded in 1951 by L. Ron Hubbard (1911-1986), and the Chinese religion, Confucianism, which originates with the teachings of Confucius (551-479 BCE). Though Hubbard admits being influenced by eastern thinking such as Buddhism and Daoism in shaping his worldview, he specifically discounts Confucius as relevant in this regard. However, through comparisons between Scientology and Confucianism, …

Intervention In Painting By Marlene Dumas With Titles Of Engagement: Ryman's Brides, Reinhardt's Daughter And Stern, Susan King Klinkenberg Jan 2009

Intervention In Painting By Marlene Dumas With Titles Of Engagement: Ryman's Brides, Reinhardt's Daughter And Stern, Susan King Klinkenberg

USF Tampa Graduate Theses and Dissertations

Marlene Dumas is known for her portraits and figurative paintings and drawings. This study focuses on three paintings by Dumas that reference male icons of art: Stern (2004), Ryman's Brides (1997), and Reinhardt's Daughter (1994). In referencing Ad Reinhardt, Robert Ryman and in the case of Stern, Gerhard Richter, Dumas engages with each artist and the history of painting in specific ways. As this thesis title indicates, I argue that Dumas uses artistic allusion pervasively throughout her oeuvre to conduct an intervention in painting. I propose that this interposition is a way to navigate and question the canon, while strengthening …

Shadows Fall On Main Street: Film Noir Travels Out Of The City, Anthony Laporte Jan 2009

Shadows Fall On Main Street: Film Noir Travels Out Of The City, Anthony Laporte

USF Tampa Graduate Theses and Dissertations

After World War II, film audiences of American crime dramas, later termed film noirs, witnessed the relocation of several film narratives to settings outside of the traditional urban environment. These films began to defy the conventional notion that crime only exists in densely populated cities and began to incorporate alternative spaces, like suburban communities, small towns, and the open road, to tell their stories. This thesis examines how social and geographical spaces contribute to, rather than oppose, a noir sensibility by employing an intertextual analysis of three film noirs set in locations out of the city: Fallen Angel, The Stranger, …

“You‟Re Going To Hollywood!”: Gender And Race Surveillance And Accountability In American Idol Contestant‟S Performances, Amanda Leblanc Jan 2009

“You‟Re Going To Hollywood!”: Gender And Race Surveillance And Accountability In American Idol Contestant‟S Performances, Amanda Leblanc

USF Tampa Graduate Theses and Dissertations

This paper examines how the reality competition television program American Idol serves to reinforce gendered, racialized and heteronormative stereotypes, particularly for female contestants. Through its "democratic" style of public audience voting, those competitors who not only sing well, but also perform their gender and race to standards which have been deemed by the judges to be appropriate mainstream American culture, prove to be the most successful on the program. Through a content analysis of the show's first four seasons, I find that those female contestants who begin their tenure in the contest by fitting into categories which would be considered …

Condition | Recondition: Reconstruction Of The City And Its Collective Memory, C Lopez

USF Tampa Graduate Theses and Dissertations

Worldwide, dense urban spaces have been organized and transformed by cultural values. However, in many cases, changes in economic and social conditions have resulted in fragmentation of neighborhood typologies, in terms of their physical characteristics and uses. Such spaces are a manifestation of development, expansion, dislocation and marginalization; a condition that can be improved through an architectural and urban strategy which inscribes emerging forces into the neglected zones of marginal territories. The contemporary context calls for a re-evaluation of public space. To fully engage the people, it is a necessary function of public space to blur landscape, architecture and infrastructure, …

A Novel Antibody Based Capture Matrix Utilizing Human Serum Albumin And Streptococcal Protein G To Increase Capture Efficiency Of Bacteria, Christie Renee Mccabe Jan 2009

A Novel Antibody Based Capture Matrix Utilizing Human Serum Albumin And Streptococcal Protein G To Increase Capture Efficiency Of Bacteria, Christie Renee Mccabe

USF Tampa Graduate Theses and Dissertations

A novel capture matrix utilizing human serum albumin (HSA) and streptococcal Protein G (PG), which possesses an albumin binding domain (ABD), was used to immobilize antibodies for improved bacterial capture efficiency in immunoassays. Enzyme linked immunosorbent assays (ELISA) were used to characterize and optimize a specific protocol for the HSA-PG capture matrix; which revealed several critical factors that should be considered. The Fc binding domain, on PG, should have high affinity for the species of capture antibody used in the assay. Goat and rabbit species antibodies bound strongly to the Fc binding domain of PG. Displacement of the capture antibody, …

“Desirable Images”: Sexual Mapping In William S. Burroughs’S Naked Lunch And Samuel R. Delany’S Dhalgren, Patrick Mcgowan

USF Tampa Graduate Theses and Dissertations

In "Postmodernism, or, the Cultural Logic of Late Capitalism," Fredric Jameson describes the disappearance, within postmodernism, of an objective framework for mapping the social totality. In order to illustrate this concept, Jameson draws upon the ideas of urban planner Kevin Lynch as formulated in his seminal work, The Image of the City. For Lynch, the design of the postwar alienated city results in varying and fragmentary "cognitive maps" used by its inhabitants to negotiate urban space, a problem that can be rectified by "good" urban planning, which aims to create mappable public space through the implementation of external orientation markers. …
