The Role Of Bacterial Lipopolysaccharide In The Production Of The Lupus B Cell Phenotype, Veljko. Nikolic Jan 2004

The Role Of Bacterial Lipopolysaccharide In The Production Of The Lupus B Cell Phenotype, Veljko. Nikolic

Electronic Theses and Dissertations 2000 - 2009

The purpose of this study was to determine the effect of bacterial lipopolysaccharide (LPS) on the expression of RP105 (CD180) in human B lymphocytes from normal, leukemic, and lupus patients. The percentage of cells that express RP105 on their surface increased following a 24 hour exposure to LPS. However, continued exposure for a total of four days resulted in a marked decrease in the expression of this receptor molecule. Human B cells were purified by a combination of density gradient and negative magnetic bead selection and maintained in culture with and without LPS. Enzyme linked immunoassay for the detection of …

Time, Place, And Agency In "Richard Ii", Jennifer Sunshine Goddard Jan 2004

Time, Place, And Agency In "Richard Ii", Jennifer Sunshine Goddard

Electronic Theses and Dissertations 2000 - 2009

In Richard II, Shakespeare left lessons for us on the effects of speech acts by leaders on the public stage. The "I" in Richard's speeches is always new: "Thus play I in one person many people" (5.5.31). Recent theories of pardons and promises made in the public sphere call attention to the layers of voices, heretofore hidden, in the first-person utterances of Richard as he attempts to interrupt the rush of history toward vengeance. Employing speech-act theory, we discover today that Shakespeare lets each utterance create a new voice and history for England. Shakespeare gives Richard time to begin to …

Time, Space, And Shakespeare: Temporal And Spatial Disturbances At The Point Of Cultural Contact, Jessica L. Murray Jan 2004

Time, Space, And Shakespeare: Temporal And Spatial Disturbances At The Point Of Cultural Contact, Jessica L. Murray

Electronic Theses and Dissertations 2000 - 2009

Cultural geographic theory uses dramatic language (place ballets , time-space routines, temporal rhythms , etc.) to describe how humans sense and dwell in places. Because the theory contemplates human behavior enacted upon a stage, it is applicable to theater studies. This thesis asserts that Hamlet's, Othello's, and Antony's treacherous lifeworlds undermine their spatiotemporal senses and initiate quests similar to those described by Anne Buttimer as searches "for order, predictability, and routine, as well as [...] for adventure and change" ("Grasping" 285). Hamlet's revenge plot is a pursuit of order and reclamation of his identity at Elsinore. Desdemona's murder is Othello's …

Value Of Worthless Lives: Italian Immigrant Autobiographies By "Ordinary People", Ilaria. Serra Jan 2004

Value Of Worthless Lives: Italian Immigrant Autobiographies By "Ordinary People", Ilaria. Serra

Electronic Theses and Dissertations 2000 - 2009

"Immigrants left tears and sweat, but no memories." This dissertation tries to prove this assertion by the Italian critic Giuseppe Prezzolini wrong. Italian immigrants have sweated and cried, but many of them also left a trace of their "heroic" voyage between two continents, and two worlds, that took place in waves during the entire XX Century. With an oxymoron, I will speak about the value of worthless lives. These authors are no conquerors, saints or celebrities, but they believe that their life stories are worth being written and remembered. There are many direct ties between the experience of migration and …

Veil And The State: Debating The Unveiling And Re-Veiling Of Women In Twentieth-Century Iran, Masoud. Talachian Jan 2004

Veil And The State: Debating The Unveiling And Re-Veiling Of Women In Twentieth-Century Iran, Masoud. Talachian

Electronic Theses and Dissertations 2000 - 2009

Hijab, the Islamic dress code, in Muslim communities is a sensitive and controversial issue. It embodies religious doctrine and patriarchal policies. However, in Iran this concept entails a more exclusive significance due to the strict nature of the Shiite faith, which is prevalent in Iran, along with a volatile political system and harsh practices of patriarchy and male domination that are legitimized by Iranian culture and traditions. The legacy of veiling in Iran is not a product of Islam and Islamic laws. Such a practice had existed in Iran centuries before the appearance of Islam in Mecca. The veil predates …

Protein Aggregation Studies: Inhibiting And Encouraging Β-Amyloid Aggregation, Jed Paul Aucoin Jan 2004

Protein Aggregation Studies: Inhibiting And Encouraging Β-Amyloid Aggregation, Jed Paul Aucoin

LSU Doctoral Dissertations

This work demonstrates peptide-based aggregation mediation of fibril forming peptides, notably β-amyloid (1-40), Aβ1-40. To achieve the goals of this work, Aβ1-40 aggregation was governed by ionic strength, temperature, and pH. After controlling and reproducing Aβ1-40 aggregate formation (fibrils), each peptide-based aggregation mediator was evaluated for its ability to self-aggregate and to possess surface-active properties. The incorporation of these mediators in Aβ1-40 solutions changed the surface tension and produced aggregate complexes of mediator and Aβ1-40. Evidence that Aβ1-40 fibril formation may be mediated by disorder-to-order transitions has been observed by layer formation …

Haunted By The Uncanny - Development Of A Genre From The Late Eighteenth To The Late Nineteenth Century, Alexandra Maria Reuber Jan 2004

Haunted By The Uncanny - Development Of A Genre From The Late Eighteenth To The Late Nineteenth Century, Alexandra Maria Reuber

LSU Doctoral Dissertations

This dissertation traces the development of the supernatural from the late eighteenth to the late nineteenth-century. Since supernatural elements are unknown and unfamiliar, they easily arouse anxiety, fear, and even result in terror. As such they produce the effect of the uncanny and introduce the psychological component into the selected literary corpus taken from the English Gothic novel, the German Schauerroman, and the French littérature fantastique. The analysis of the selected material is based on a psychoanalytical approach using Sigmund Freud’s understanding of the uncanny, his dream analysis, and his view of the conscious and unconscious, but also considers Carl …

Replication Of Metal-Based High-Aspect Microscale Structures By High Temperature Micromolding, Dongmei Cao Jan 2004

Replication Of Metal-Based High-Aspect Microscale Structures By High Temperature Micromolding, Dongmei Cao

LSU Doctoral Dissertations

In microsystem technology a large range of materials will be available only after the necessary microfabrication technologies have been developed or adapted. More than a decade ago, the existing microfabrication technologies were restricted to structuring and shaping techniques producing three-dimensional microstructures out of silicon, mostly unfilled plastics or a few pure metals or binary alloys. However, the choice of materials for microcomponents is determined by the function and conditions of use of microsystems. Some microdevices can only work well when made of specific metal components. To meet this need, several microfabrication techniques have been developed, such as second electroforming of …

Thermodynamic Characterization Of Dna Binding By Type I Dna Polymerases From Thermus Aquaticus And Escherichia Coli, Kausiki Datta Jan 2004

Thermodynamic Characterization Of Dna Binding By Type I Dna Polymerases From Thermus Aquaticus And Escherichia Coli, Kausiki Datta

LSU Doctoral Dissertations

DNA binding of the DNA polymerase I from Thermus aquaticus (Taq and Klentaq fragment) and E. coli (Klenow fragment) have been studied as a function of [salt] and temperature in order to understand their DNA binding thermodynamics. Binding of the two different species of polymerases occurs with sub-micromolar affinities in very different salt concentration ranges. Thus, at similar [KCl] the binding of Klenow is ~ 3kcal/mol (150X) tighter than the binding of Taq/Klentaq. Linkage analysis of the [KCl] dependence of DNA binding at 25°C reveals a net release of 2-3 ions for Taq/Klentaq and 4-5 ions for Klenow. DNA binding …

A Distributed Quadtree Dictionary Approach To Multi-Resolution Visualization Of Scattered Neutron Data, Rion Dooley Jan 2004

A Distributed Quadtree Dictionary Approach To Multi-Resolution Visualization Of Scattered Neutron Data, Rion Dooley

LSU Doctoral Dissertations

Grid computing is described as dependable, seamless, pervasive access to resources and services, whereas mobile computing allows the movement of people from place to place while staying connected to resources at each location. Mobile grid computing is a new computing paradigm, which joins these two technologies by enabling access to the collection of resources within a user's virtual organization while still maintaining the freedom of mobile computing through a service paradigm. A major problem in virtual organization is needs mismatch, in which one resources requests a service from another resources it is unable to fulfill, since virtual organizations are necessarily …

Analysis Of Bacterial Diversity And Biogeography At The Central Arizona-Phoenix Long Term Ecological Research (Cap Lter) Site, Brian Anthony Rash Jan 2004

Analysis Of Bacterial Diversity And Biogeography At The Central Arizona-Phoenix Long Term Ecological Research (Cap Lter) Site, Brian Anthony Rash

LSU Doctoral Dissertations

The limiting factor involved in past assessments of soil bacterial diversity when using culture-independent techniques has often been the lack of sampling and replication. As a result, analyses of community structural shifts across soil environments have lacked statistical power. In this study, 23 16S rRNA gene clone libraries consisting of over 11,000 clones were constructed from soils at the Central Arizona Phoenix Long Term Ecological Research (CAP LTER) site. Subsequent ARDRA fingerprinting and partial 16S rRNA gene sequencing allowed for a more robust investigation of various components that may explain any observed variations in bacterial species composition. The designated land …

The Relation Between Knowledge Of Adhd And Treatment Acceptability In A Multi-Disciplinary Pediatric Clinic, Rebecca Owen Currier Jan 2004

The Relation Between Knowledge Of Adhd And Treatment Acceptability In A Multi-Disciplinary Pediatric Clinic, Rebecca Owen Currier

LSU Doctoral Dissertations

Behavior modification and medication have been proven to be the most effective interventions for children with ADHD. For these treatments to be effective, utilization of mental health care services as well as compliance with treatment recommendations is necessary. There has been shown lower care utilization among minorities for the treatment of behavioral disorders. In addition, lack of adherence among these populations to ADHD treatment is not explained by SES, parenting stress, or family coping. An alternative explanation may be parental knowledge of ADHD and opinions of commonly used treatments. The present investigation examined the effect of a brief knowledge intervention …
