Synthesis And Surface Characterization Of Silica-Polypeptide Composite Particles, Erick Isael Soto-Cantu Jan 2008

Synthesis And Surface Characterization Of Silica-Polypeptide Composite Particles, Erick Isael Soto-Cantu

LSU Doctoral Dissertations

The synthesis and sequential surface characterization of silica-polypeptide composite particles is described. Nearly monodisperse colloidal silica cores were obtained by the alkaline hydrolysis of tetraethyl orthosilicate (TEOS). The hydrodynamic radius can be easily controlled in the range of ƒî 20-140 nm by the water/TEOS ratio in the starting reaction mixture. The surface of the synthesized silica cores was further passivated/functionalized (P/F) by a mixture of (3-aminopropyl) trimethoxysilane (APS) and methyl-trimethoxysilane (MTMS). The amino groups were quantified using UV-Vis spectrometry after reaction with ninhydrin. The use of zeta potential measurements of the P/F silica particles at low pH is presented as …

How To Remember Thee?: Problems Of Memorialization In English Writing, 1558-1625, Sean Flory Jan 2008

How To Remember Thee?: Problems Of Memorialization In English Writing, 1558-1625, Sean Flory

LSU Doctoral Dissertations

This dissertation focuses on the use of funeral commemoration in religious and political controversies in early modern England. By examining the rhetoric used in funeral sermons and elegies, I show that commemorative writers use figural interpretation of the Bible to legitimize praise by linking the deceased to characters from scripture. Figural interpretation places the dead into a framework of ecclesiastical history and creates Protestant saints used as exempla in political and religious debates. This dissertation examines funeral sermons, elegies, and other commemorative poems written between 1558 and 1625. Chapter one discusses the development of figural interpretation in Elizabethan funeral sermons. …

Incorporation Of Cα,Α-Disubstituted Amino Acids Into Model Peptide Systems: Conformational Analysis And Possible Applications As Therapeutic Agents, Marcus A. Etienne Jan 2008

Incorporation Of Cα,Α-Disubstituted Amino Acids Into Model Peptide Systems: Conformational Analysis And Possible Applications As Therapeutic Agents, Marcus A. Etienne

LSU Doctoral Dissertations

A diverse set of human diseases is associated with the misfolding of proteins into insoluble fibrillar structures that have predominantly β-sheet secondary structure. Thus it is imperative to elucidate the structural elements that contribute to β-sheet formation and stability. Peptides that autonomously form β-sheets are ideal models to study principles of protein folding and design. Gellman and coworkers first introduced an automonously folded β-hairpin (H-Arg-Tyr-Val-Glu-Val-Yyy-Xxx-Orn-Lys-Ile-Leu-Gln-NH2) that remained monomeric up to ~1 mM. Circular dichroism (CD) and nuclear magnetic resonance (NMR) analyses revealed that incorporation of non-stereogenic Aib-Xxx dipeptidyl sequences into i+1 and i+2 positions of a model peptide nucleates a …

Chemical Analysis Of Polymer Blends Via Synchrotron X-Ray Tomography, Heath Alan Barnett Jan 2008

Chemical Analysis Of Polymer Blends Via Synchrotron X-Ray Tomography, Heath Alan Barnett

LSU Doctoral Dissertations

Material properties of industrial polymer blends are of great importance. X-ray tomography has been used to obtain spatial chemical information about various polymer blends. The spatial images are acquired with synchrotron X-ray tomography because of its rapidity, good spatial resolution, large field-of-view, and elemental sensitivity. The spatial absorption data acquired from X-ray tomography experiments is converted to spatial chemical information via a linear least squares fit of multi-spectral X-ray absorption data. A fiberglass-reinforced polymer blend with a new-generation flame retardant is studied with multi-energy synchrotron X-ray tomography to assess the blend homogeneity. Relative to other composite materials, this sample is …

Dactyls Reveal Evolutionary Patterns In Decapod Crustaceans, Jeffrey Guy Agnew Jan 2008

Dactyls Reveal Evolutionary Patterns In Decapod Crustaceans, Jeffrey Guy Agnew

LSU Doctoral Dissertations

Because of their high preservation potential and uses in foraging and defense, decapod crustacean dactyls (movable fingers of claws) are potentially excellent test subjects for an ongoing debate concerning the relative importance of top-down (predators) and bottom-up (prey) controls on morphologic diversification and evolution. The utility of dactyls for inferring evolutionary patterns were evaluated using living and subfossil xanthoid crabs sampled from the southeast U.S. Atlantic and Gulf of Mexico coasts, and were used to: (1) distinguish the roles of selection and constraint on dactyl morphology through allometric and shape comparisons in the context of the crab’s phylogenetic relationships and …

Numerical Simulations Of Flow And Mass Transport In Micro-Fluidic Components For Modular Bio-Analytic Chip Applications, Sudheer D. Rani

LSU Doctoral Dissertations

Microfluidics has received a great deal of attention in the past decade. The ability of modular microfluidic chips to miniaturize integrate chemical and biological systems (µTAS) can be greatly productive in terms of cost and efficiency. During the design of these modular devices, misalignment of materials, geometrical or both is one of the most common problems. These misalignments can have adverse effect in both pressure driven and electrokinetically driven flows. In the present work, Numerical Simulations have been performed to study the effect of material and geometrical mismatch on the flow behavior and species progression in microfluidic interconnects. In the …

Teachers' Perspectives On The Unintended Consequences Of High Stakes Testing, David Christopher Charles Jan 2008

Teachers' Perspectives On The Unintended Consequences Of High Stakes Testing, David Christopher Charles

LSU Doctoral Dissertations

A mixed methods design was utilized that was divided into three phases to verify and explore high stakes testing’s effects on teachers’ perceptions regarding classroom practices, pressure, and commitment to the educational profession. Phase I utilized previous surveys and a peer review to create a knowledge base to generate a survey instrument that measured the three areas assumed to be affected by high stakes testing (commitment, pressure, and classroom practice). The survey instrument that was created was piloted. Throughout Phase II there was a series of three-step analysis: First, the means and standard deviations from the results of the surveys …

Heterogeneous Catalyzed Macromolecular Hydrogenations In Oscillating Systems, Alan Bussard Jan 2008

Heterogeneous Catalyzed Macromolecular Hydrogenations In Oscillating Systems, Alan Bussard

LSU Doctoral Dissertations

An examination of novel oscillatory (alternating gas and liquid phase) reactors and heterogeneous catalysts for multi-phase macromolecular reactions was carried out. A monolith-containing square die with Pd/Al2O3 catalysts was used to successfully hydrogenate poly(styrene) (PS). The inherent pulse behavior of the extruder was found to be sufficient to approach intrinsic kinetics at low polymer concentrations. At higher (10 wt% PS) concentrations, forced pulsing was shown to have a greater impact on observed reaction rates. Selectivity with this extruder-fed reactor was better than with a stirred tank in all cases, due to a more plug-flow-like residence time distribution. While accurate control …

A Genetic Bayesian Approach For Texture-Aided Urban Land-Use/Land-Cover Classification, Wenxue Ju Jan 2008

A Genetic Bayesian Approach For Texture-Aided Urban Land-Use/Land-Cover Classification, Wenxue Ju

LSU Doctoral Dissertations

Urban land-use/land-cover classification is entering a new era with the increased availability of high-resolution satellite imagery and new methods such as texture analysis and artificial intelligence classifiers. Recent research demonstrated exciting improvements of using fractal dimension, lacunarity, and Moran’s I in classification but the integration of these spatial metrics has seldom been investigated. Also, previous research focuses more on developing new classifiers than improving the robust, simple, and fast maximum likelihood classifier. The goal of this dissertation research is to develop a new approach that utilizes a texture vector (fractal dimension, lacunarity, and Moran’s I), combined with a new …

Mother-Daughter Communication And Media Influence On Self-Esteem And Body Image, Tori Austin Jan 2008

Mother-Daughter Communication And Media Influence On Self-Esteem And Body Image, Tori Austin

Dissertations and Theses @ UNI

Societal norms based on media venues influence the perception young females have of themselves; however, some literature indicates the mother daughter relationship can help minimize the possible negative effects. Young women are more susceptible to desire distorted media images of glamorous and thin women. As they make social comparisons with mediated images of womanhood, they may become disappointed in their own body image and possess lower self-esteem. The previous research has gaps when discussing mother daughter relationships, media's influence, and the impact on adolescent girls' self-esteem and body image. To determine predictors to young women's self-esteem and body image, 119 …
