Characterization Of Protein Secretion In Mycobacterium Leprae Using Phoa Fusions In Escherichia Coli And Mycobacterium Smegmatis, Marina Noemi Torrero Jan 2003

Characterization Of Protein Secretion In Mycobacterium Leprae Using Phoa Fusions In Escherichia Coli And Mycobacterium Smegmatis, Marina Noemi Torrero

LSU Doctoral Dissertations

Complete sequencing and annotation of the M. leprae genome has provided new information related to proteins constituting its hypothetical proteome. Since M. leprae can not be grown in vitro, novel approaches are needed to determine which proteins are expressed during infection and whether these proteins are related to pathogenesis. Secreted proteins represent a distinct group of protein with respect to their structure and function, contribution to virulence and are of particular importance for vaccine development because they are often immunogenic and have the potential to be recognized early in infection. The objectives of this study were: 1) to identify putatively …

A Novel Hydrogen And Oxygen Generation System, Zhiyong Peng Jan 2003

A Novel Hydrogen And Oxygen Generation System, Zhiyong Peng

LSU Master's Theses

This study examined the three phases of the sorption-enhanced SMR process for H2 production: production of low-CO hydrogen using the standard Ni-based reforming catalyst and high purity CaO sorbent precursor, evaluation of combined reforming catalyst-sorbent samples supplied by TDA, and an Aspen simulation study of the process for simultaneous production of H2 and O2. The production of low-CO (<20ppmv) hydrogen was studied using the single-step sorption-enhanced steam methane reforming process. The effects of temperature, volumetric feed rate, and feed gas composition on the purity of H2 and the content of CO were investigated. The feasibility of producing 95+% H2 with CO content of less than 20ppmv was experimentally proven in a test at 480¡ãC and 5 atm using a commercial Ni-based catalyst and the calcium-based CO2 sorbent. The feed gas contained 20% CH4 and 80% H2O, while the product gas contained 97.8% H2 and 17 ppmv CO. With this low CO concentration, the product can be used in a proton exchange membrane (PEM) fuel cell without further purification. The catalyst-sorbent samples from TDA Research Inc. were extensively studied and evaluated with respect to their performance in the steam-reforming reaction using both the fixed-bed reactor system and TGA. The activity of the catalyst samples having different compositions was examined and compared at different temperatures and space velocities using a feed gas containing 11.1% CH4 with a steam-to-carbon (S/C) ratio of 3.0. The sorption activity and durability was also examined in the TGA system. The overall hydrogen and oxygen co-production process was studied and evaluated using the Aspen Plus simulator. Material and energy balance calculations showed that this system can produce 99+% purity hydrogen and oxygen simultaneously with efficient energy integration. This process is balanced on power consumption and generation, so no external power is required.

"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle Jan 2003

"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle

LSU Master's Theses

This thesis claims that Shakespeare exaggerated the characterization of two figures in Romeo and Juliet, Friar Laurence and the apothecary, to make a statement about the conditions of medical treatment in sixteenth century London. These two figures represent two very different approaches to healing, one that is informed with ancient holistic medical theory and one that is driven by economics, and this work attempts to explain the cultural conditions that warranted such a discrepancy in the play. I address these two medical figures in the contexts of the events of the text, of the contemporary medical profession, and of materialism …

Predicting Ghanaian Pre-Service Teachers' Intention To Teach High-Risk Sexual Behavior Prevention From Teaching Efficacy And Prevention Approach, Joseph Kwesi Ogah Jan 2003

Predicting Ghanaian Pre-Service Teachers' Intention To Teach High-Risk Sexual Behavior Prevention From Teaching Efficacy And Prevention Approach, Joseph Kwesi Ogah

Dissertations and Theses @ UNI

Youth and adolescents in African Countries have been experiencing high prevalence levels of the outcomes of high-risk sexual behavior (HRSB), such as HIV/AIDS, teenage pregnancy, illegal abortions, and dropping out of school. Education is one means by which HRSB can be reduced among adolescents, but the sensitive nature of sex education and the controversy over which prevention approach to use have made the teaching of HRSB prevention in schools a cautious undertaking. The purpose of this study was to describe (a) pre-service teachers’ efficacy beliefs for teaching HRSB prevention and (b) pre-service teachers’ preferred approach to HRSB prevention, as determinants …

Developing A Conceptual System Model For Ecological Integrity Planning In The Greater Kluane Region, Yukon, Brent Heyward Parker

Theses and Dissertations (Comprehensive)

Understanding the complexity and ecological organization of protected area ecosystems, and their bioregional surroundings, is fundamental to maintaining their integrity. This research set out to integrate the bodies of systems and hierarchy theory to establish a framework for developing a conceptual model that would synthesize knowledge from diverse fields and identify key system processes, thereby providing new insight into ecosystem organization, function, and integrity. This understanding was then applied to planning for ecological integrity in the Canadian National Parks context through a case study of Kluane National Park and Reserve (KNP&R) within the Greater Kluane Region (GKR).

The Impact Of Whole-Plant Instruction Preservice Elementary Teachers' Understanding Of Plant Science Principles, Christine Collins Hypolite Jan 2003

The Impact Of Whole-Plant Instruction Preservice Elementary Teachers' Understanding Of Plant Science Principles, Christine Collins Hypolite

LSU Doctoral Dissertations

The purpose of this research was to determine how an inquiry-based, whole-plant instructional strategy would affect preservice elementary teachers’ understanding of plant science principles. This study probed: what preservice teachers know about plant biology concepts before and after instruction, their views of the interrelatedness of plant parts and the environment, how growing a plant affects preservice teachers’ understanding, and which types of activity-rich plant themes studies, if any, affect preservice elementary teachers’ understandings. The participants in the study were enrolled in two elementary science methods class sections at a state university. Each group was administered a preinstructional test at the …

Role Of Endothelin-1 In The Gastrointestinal Tract Of Horses In Health And Disease, Ramaswamy Monickarasi Chidambaram Jan 2003

Role Of Endothelin-1 In The Gastrointestinal Tract Of Horses In Health And Disease, Ramaswamy Monickarasi Chidambaram

LSU Doctoral Dissertations

Gastrointestinal tract disease is the leading natural cause of death in horses and horses with ischemic intestinal disease have the greatest mortality. We hypothesized there is basal synthesis of endothelin-1 (ET-1) in the intestinal tract of healthy horses that is likely involved in regulating vasomotor tone, secretion and motility and that ET-1 synthesis increases with gastrointestinal tract disease, which may be involved in the pathophysiology of these disorders. Plasma ET-like immunoreactivity was increased in horses with naturally-acquired gastrointestinal disease, compared with normal horses; values were greatest in horses with large intestinal strangulation obstruction, enterocolitis and peritonitis. There was an association …

Major And Minor Life Events As Predictors Of Medical Utilization, Gareth R. Dutton Jan 2003

Major And Minor Life Events As Predictors Of Medical Utilization, Gareth R. Dutton

LSU Master's Theses

Research suggests stressful life events can negatively influence physical and mental health in a number of ways. While previous research indicates both major and minor life events contribute unique variance to the prediction of physical and mental symptoms, little research has examined the relationships of both major and minor life events with medical utilization. The current study included a predominantly African American, low-income sample of adults (N = 207) attending two primary care outpatient clinics and assessed their experience of both major and minor life events over the course of one year. Medical utilization data were collected over a subsequent …

The Determination Of Appropriate Phosphogypsum: Class C Fly Ash : Portland Type Ii Cement Compositions For Use In Marine Applications, Pradyot Sudhakar Deshpande

LSU Master's Theses

Phosphogypsum (PG, CaSO4·2H2O) is a waste by-product produced during the wet manufacturing phosphoric acid process. Phosphoric acid is manufactured by processing phosphate rock that contains relatively high concentrations of naturally occurring radioactive impurities which makes PG a radioactive material. PG also contains certain trace metals including As, Ba, Cd, Cr and Pb and radioactive contaminants such as Radium226 and Uranium238 that pose potential hazard to human health and the environment. According to USEPA, the current allowable disposal method for PG is stack piling. This research was focused on stabilizing PG with Portland Type II …

Level Of Essentialness Of A Node In Flowcharts And Its Application To Program Testing, Osman Kandara Jan 2003

Level Of Essentialness Of A Node In Flowcharts And Its Application To Program Testing, Osman Kandara

LSU Doctoral Dissertations

Program testing is important to develop bug free software. A common form of program testing involves selecting test cases which execute (cover) a given set W of statements in the program. In regression testing, W typically forms a small subset of the program. It is often possible to find an alternate small set W so that execution of W' implies execution of W. We develop concepts and algorithms for finding W' as small as possible with the condition that the statements in W' are "close" to those in W in terms of program structure. These concepts generalize the notion of …

Beyond Boundaries: Political Dictates Found In Minstrelsy, Florence Lyons-Fontenot Jan 2003

Beyond Boundaries: Political Dictates Found In Minstrelsy, Florence Lyons-Fontenot

LSU Doctoral Dissertations

Nineteenth-century white minstrels portrayed white abolitionists, suffragists, and temperance advocates in blackface, in order discriminate against them in the same way that blacks were discriminated against in minstrel performances. When minstrels blackened their faces to portray these white political advocates, the advocates were transformed into black caricatures, which demeaned the advocates as well as the political causes they supported. The separatist discourse, stressed in minstrelsy, typified the ideology of anti-abolitionist mobs and was used to symbolize their violence against white abolitionists and blacks. In 1850 minstrel performers used minstrelsy to protest suffrage. Since minstrels portrayed white suffragists the same way …

Biology And Ecology Of Leptographium Species And Their Vectos As Components Of Loblolly Pine Decline, Lori G. Eckhardt Jan 2003

Biology And Ecology Of Leptographium Species And Their Vectos As Components Of Loblolly Pine Decline, Lori G. Eckhardt

LSU Doctoral Dissertations

Loblolly pine (Pinus taeda L.) decline (LPD) has been present in upland sites of central Alabama since the 1960s. Symptoms of LPD (fine root deterioration, short chlorotic needles, sparse crowns, reduced radial growth) begin in the 30-40 yr age class, resulting in premature death at ages 35-50. Previously, declining loblolly was diagnosed as littleleaf disease (LLD); however, site conditions associated with LPD are different from LLD sites. Littleleaf disease only occurs on eroded, heavy clay soils and is secondarily associated with the fungus, Phytophthora cinnamomi. In contrast, LPD occurs on sandy, well-drained soils and is associated with Leptographium spp., as …

Ultrasonic Characterization Of Engineering Performance Of Oriented Strandboard, Ronnie Yunheu Vun Jan 2003

Ultrasonic Characterization Of Engineering Performance Of Oriented Strandboard, Ronnie Yunheu Vun

LSU Doctoral Dissertations

Direct-contact (DC) and non-contact (NC) ultrasonic transmission (UT) methods were developed to characterize the structural performance of oriented strandboard (OSB). The UT variable velocity was shown to be sensitive to the physical impediments caused by flake interfacial boundaries and embedded voids. Both attenuation and root mean square (RMS) voltage were good indicators of the “zero void” densification level for OSB, a point of the greatest transmissivity of the stress wave energy. For both DC and NC methods, the predicted densities of the model were validated for spatial distribution over each OSB type. Based on the EN300 standard for panel manufacturing, …

Characteristics Of Fat Free Yogurt As Influenced By The Incorporation Of Folic Acid, Charles August Boeneke Jan 2003

Characteristics Of Fat Free Yogurt As Influenced By The Incorporation Of Folic Acid, Charles August Boeneke

LSU Doctoral Dissertations

Folic acid fortification is used in the prevention of neural tube defects such as spina bifida and ancencephaly, heart defects, facial clefts, urinary tract abnormalities, and limb deficiencies. Although yogurt is not a good source of folic acid, fortification could aid in prevention of above mentioned defects. Fortification of yogurt with folic acid may or may not change its physico-chemical characteristics. Fat free sugar free yogurt was manufactured using 0, 25%, 50%, 75% and 100% of the recommended daily allowance of 400 micrograms of folic acid. Treatments included addition of folic acid at these levels before and after pasteurization. Lemon …
