Porphyrin Depth In Lipid Bilayers As Determined By Iodide And Parallax Fluorescence Quenching Methods And Its Effect On Photosensitizing Efficiency, Irena Bronshtein, Michal Afri, Hana Weitman, Aryeh A. Frimer, Kevin M. Smith, Benjamin Ehrenberg

Faculty Publications

Photosensitization by porphyrins and other tetrapyrrole chromophores is used in biology and medicine to kill cells. This light-triggered generation of singlet oxygen is used to eradicate cancer cells in a process dubbed "photodynamic therapy," or PDT. Most photosensitizers are of amphiphilic character and they partition into cellular lipid membranes. The photodamage that they inflict to the host cell is mainly localized in membrane proteins. This photosensitized damage must occur in competition with the rapid diffusion of singlet oxygen through the lipid phase and its escape into the aqueous phase. In this article we show that the extent of damage can …

Camptothecin Accumulation In Camptotheca Acuminata Seedlings In Response To Acetylsalicylic Acid Treatment, Zhanhai Li, Zhijun Liu Jan 2004

Camptothecin Accumulation In Camptotheca Acuminata Seedlings In Response To Acetylsalicylic Acid Treatment, Zhanhai Li, Zhijun Liu

Faculty Publications

Camptothecin is an anti-cancer alkaloid. Acetylsalicylic acid (ASA) treatment was evaluated as a potential tool for increasing camptothecin accumulation (concentration and yield) in Camptotheca acuminata. Increasing ASA concentration increased leaf camptothecin concentration, but stunted growth and decreased total leaf camptothecin yield. Thus, ASA treatment does not enhance camptothecin yield.

Media Coverage Of The 2003 Parliamentary Election In The Republic Of Georgia, Baadur Koplatadze Jan 2004

Media Coverage Of The 2003 Parliamentary Election In The Republic Of Georgia, Baadur Koplatadze

LSU Master's Theses

The November 2, 2003, parliamentary election caused a significant political crisis in the Republic of Georgia. During the election campaign, the political parties questioned the desire of the government to carry out a fair election. They blamed President Edward Shevardnadze for fabricating the election. After the election, the opposition parties did not recognize the results and claimed that there were massive fabrications (the number of people who voted was much more than the number of people who were in voters’ list). The public supported this position, and several huge demonstrations demanded the resignation of President Shevardnadze. Two weeks after the …


Numerical Solution Of Fractional Advection-Dispersion Equation, Zhi Qiang Deng, Vijay P. Singh, Lars Bengtsson Jan 2004

Numerical Solution Of Fractional Advection-Dispersion Equation, Zhi Qiang Deng, Vijay P. Singh, Lars Bengtsson

Faculty Publications

Numerical schemes and stability criteria are developed for solution of the one-dimensional fractional advection-dispersion equation (FRADE) derived by revising Fick's first law. Employing 74 sets of dye test data measured on natural streams, it is found that the fractional order F of the partial differential operator acting on the dispersion term varies around the most frequently occurring value of F=1.65 in the range of 1.4 to 2.0. Two series expansions are proposed for approximation of the limit definitions of fractional derivatives. On this ground, two three-term finite-difference schemes - "1.3 Backward Scheme"having the first-order accuracy and "F.3 Central Scheme"possessing the …

Travels In Louisiana: Journeys Into Ethnicity And Heritage By Two Hispanic Groups, Dominica Dominguez Ramirez Jan 2004

Travels In Louisiana: Journeys Into Ethnicity And Heritage By Two Hispanic Groups, Dominica Dominguez Ramirez

LSU Master's Theses

This thesis addresses how the notions of ethnicity and heritage are experienced, negotiated, and displayed by two Hispanic groups in Louisiana. Hispanic identity is a nebulous term anywhere and Louisiana is no exception. In this investigation the two groups- a heritage foundation of descendants of Canary Islanders and descendants of the of the Los Adaes communities- both profess Hispanic heritage, display it, and promote this heritage in divergent ways, with significant differences in the meaning of their heritages. Differences between groups are also reflected in the historical spatial representations of the two groups, with Isleños connecting with a far-away but …

Enhanced Flushing With Cyclodextrin For The Remediation Of Creosote Contaminated Soil, Monalisa Dutta Jan 2004

Enhanced Flushing With Cyclodextrin For The Remediation Of Creosote Contaminated Soil, Monalisa Dutta

LSU Master's Theses

Past practices of applying creosote and coal tar preservatives to wood, such as unlined pits and trenches, have resulted in contamination of the surface and ground water at thousand of sites. The low aqueous solubility, volatility and bioavailability of many these constituents limit their degradation by natural attenuation and standard remediation techniques such as ground water flushing, soil vapor extraction, and bioremediation. While research has shown that cyclodextrin solutions have the ability to enhance the solubility of some of the components of creosote, additional work is needed to evaluate its potential as a remedial agent for these sites. Equilibrium batch …

German Stereotypes In British Magazines Prior To World War I, William F. Bertolette Jan 2004

German Stereotypes In British Magazines Prior To World War I, William F. Bertolette

LSU Master's Theses

The British image of Germany as England's "poor relation," a backward cluster of feudal states, gave way during the nineteenth century to the stereotype of England's archenemy and imperial rival. This shift from innocuous Old Germany to menacing New Germany accelerated after German unification in 1871 as German economic growth and imperial ambitions became topics for commentary in British journals. But the stereotypical "German Michael," or rustic simpleton, and other images of self-effacing servile, loyal, honest and passive Old Germany lingered on into the late nineteenth century as a "straw man" for alarmist Germanophobes to dispel with new counter-stereotypes. These …

Post Monitoring Of A Cyclodextrin Remediated Chlorinated Solvent Contaminated Aquifer, Rebecca Mary Hinrichs Jan 2004

Post Monitoring Of A Cyclodextrin Remediated Chlorinated Solvent Contaminated Aquifer, Rebecca Mary Hinrichs

LSU Master's Theses

Hydroxypropyl-β-cyclodextrin (HPβCD) has been tested successfully in the laboratory and in the field for enhanced flushing of low-polarity contaminants from aquifers. The cyclodextrin molecule forms a toroidal structure, which has a hydrophobic cavity. Within this cavity, organic compounds of appropriate shape and size can form inclusion complexes, which is the basis for the use of cyclodextrin in groundwater remediation. The hydrophilic exterior of the molecule makes cyclodextrin highly water-soluble. The solubility of cyclodextrins can be further enhanced by adding functional groups, such as hydroxypropyl groups, to the cyclodextrin core. The aqueous solubility of HPβCD exceeds 950 g/L. These high solubilities …


A Performer's Guide To Virgil Thomson's Five Songs From William Blake, Andrew David Whitfield Jan 2004

A Performer's Guide To Virgil Thomson's Five Songs From William Blake, Andrew David Whitfield

LSU Doctoral Dissertations

Though perhaps his most well-known vocal works might be his operas, Four Saints in Three Acts and The Mother of Us All, American composer Virgil Thomson (1896-1989) did write nearly seventy songs for voice and piano, including several important song cycles. One of these cycles, the Five Songs from William Blake, represents an impressive composition for the baritone voice. Unfortunately, much of the previous scholarship about Thomson did not award these Blake songs adequate attention, nor was it able to draw upon many of the primary sources about Thomson’s life and work that are now available. The purpose of this …

Arrive, Explore, Reflect: The Development And Evaluation Of A Web-Based Program To Introduce High School Students To Landscape Architecture, Courtney Bailey

LSU Master's Theses

The profession of landscape architecture has struggled with public perception since the mid-nineteenth century. Community programs, coloring books, and educational toolkits are just some of the methods employed in the profession's attempt to improve public perception. Very little research has been conducted to test the efficiency of these educational attempts. The goal of this thesis is to create a Web-based program to effectively educate young members of the public. The program uses five "mini lessons" to present information about landscape architecture to the student. Links to the World Wide Web are scattered throughout the program to supplement lesson material. A …
