Description
Bioparticles comprise a diverse amount of materials ubiquitously present in nature. From proteins to aerosolized biological debris, bioparticles have important roles spanning from regulating cellular functions to possibly influencing global climate. Understanding their structures, functions, and properties provides the necessary tools to expand our fundamental knowledge of biological systems and exploit them for useful applications. In order to contribute to this efforts, the work presented in this dissertation focuses on the study of electrokinetic properties of liposomes and novel applications of bioaerosol analysis. Using immobilized lipid vesicles under the influence of modest (less than 100 V/cm) electric fields, a novel strategy for bionanotubule fabrication with superior throughput and simplicity was developed. Fluorescence and bright field microscopy was used to describe the formation of these bilayer-bound cylindrical structures, which have been previously identified in nature (playing crucial roles in intercellular communication) and made synthetically by direct mechanical manipulation of membranes. In the biological context, the results of this work suggest that mechanical electrostatic interaction may play a role in the shape and function of individual biological membranes and networks of membrane-bound structures. A second project involving liposomes focused on membrane potential measurements in vesicles containing trans-membrane pH gradients. These types of gradients consist of differential charge states in the lipid bilayer leaflets, which have been shown to greatly influence the efficacy of drug targeting and the treatment of diseases such as cancer. Here, these systems are qualitatively and quantitatively assessed by using voltage-sensitive membrane dyes and fluorescence spectroscopy. Bioaerosol studies involved exploring the feasibility of a fingerprinting technology based on current understanding of cellular debris in aerosols and arguments regarding sampling, sensitivity, separations and detection schemes of these debris. Aerosolized particles of cellular material and proteins emitted by humans, animals and plants can be considered information-rich packets that carry biochemical information specific to the living organisms present in the collection settings. These materials could potentially be exploited for identification purposes. Preliminary studies evaluated protein concentration trends in both indoor and outdoor locations. Results indicated that concentrations correlate to certain conditions of the collection environment (e.g. extent of human presence), supporting the idea that bioaerosol fingerprinting is possible.

Description
Applications of non-traditional stable isotope variations are moving beyond geosciences to biomedicine, made possible by advances in multiple collector inductively coupled plasma mass spectrometry (MC-ICP-MS) technology. Mass-dependent isotope variation can provide information about the sources of elements and the chemical reactions that they undergo. Iron and calcium isotope systematics in biomedicine are relatively unexplored but have great potential scientific interest due to their essential nature in metabolism. Iron, a crucial element in biology, fractionates during biochemically relevant reactions. To test the extent of this fractionation in an important reaction process, equilibrium iron isotope fractionation during organic ligand exchange was determined. The results show that iron fractionates during organic ligand exchange, and that isotope enrichment increases as a function of the difference in binding constants between ligands. Additionally, to create a mass balance model for iron in a whole organism, iron isotope compositions in a whole mouse and in individual mouse organs were measured. The results indicate that fractionation occurs during transfer between individual organs, and that the whole organism was isotopically light compared with food. These two experiments advance our ability to interpret stable iron isotopes in biomedicine. Previous research demonstrated that calcium isotope variations in urine can be used as an indicator of changes in net bone mineral balance. In order to measure calcium isotopes by MC-ICP-MS, a chemical purification method was developed to quantitatively separate calcium from other elements in a biological matrix. Subsequently, this method was used to evaluate if calcium isotopes respond when organisms are subjected to conditions known to induce bone loss: 1) Rhesus monkeys were given an estrogen-suppressing drug; 2) Human patients underwent extended bed rest. In both studies, there were rapid, detectable changes in calcium isotope compositions from baseline - verifying that calcium isotopes can be used to rapidly detect changes in bone mineral balance. By characterizing iron isotope fractionation in biologically relevant processes and by demonstrating that calcium isotopes vary rapidly in response to bone loss, this thesis represents an important step in utilizing these isotope systems as a diagnostic and mechanistic tool to study the metabolism of these elements in vivo.

Description
The most horrific, darkest, and powerful forms of the sublime take place inside the enclosure of the human psyche; the interior of the mind is the playground for the sublime--not the crag and canyon filled natural world. For Immanuel Kant and Edmund Burke, the driving force of the power of the sublime stems from the feelings of pain and fear: where is that more manifested than in the mind? Unlike the common, traditional, and overwhelmed discussion of Percy Shelley and his contemporaries and the power of the sublime in nature, I will argue that in The Cenci, Shelley, through well-chosen diction and precise composition of terrifying images, fashions characters and scenes in an emotion-driven play that elevates the mind of the reader to a transcendent sublime experience. Through a discussion of the theories of the aesthetic of the sublime laid out by Longinus, Burke, and Kant, I will provide a foundation for the later discussion of the rhetorical sublime evoked by Shelley in the ardent and horrifying play that is The Cenci. Looking at the conventional application of the theories of the sublime to romantic writing will make evident the holes in the discussion of the sublime and romantic writings that have almost forgotten the powerful and psychological rhetorical aspect of the sublime that is emphasized in the theoretical writings of both Burke and Kant. To clarify what is traditionally associated with Shelley and the sublime, a brief analysis of the Shelleyean sublime and Shelley's 1816 poem "Mont Blanc" will prepare the reader for an unconventional, but every bit important and powerful, function of the sublime in the 1819 play The Cenci based on the horrific happenings of a historical 16th century Italian noble family.

Description
The electrode-electrolyte interface in electrochemical environments involves the understanding of complex processes relevant for all electrochemical applications. Some of these processes include electronic structure, charge storage, charge transfer, solvent dynamics and structure and surface adsorption. In order to engineer electrochemical systems, no matter the function, requires fundamental intuition of all the processes at the interface. The following work presents different systems in which the electrode-electrolyte interface is highly important. The first is a charge storage electrode utilizing percolation theory to develop an electrode architecture producing high capacities. This is followed by Zn deposition in an ionic liquid in which the deposition morphology is highly dependant on the charge transfer and surface adsorption at the interface. Electrode Architecture: A three-dimensional manganese oxide supercapacitor electrode architecture is synthesized by leveraging percolation theory to develop a hierarchically designed tri-continuous percolated network. The three percolated phases include a faradaically-active material, electrically conductive material and pore-former templated void space. The micropores create pathways for ionic conductivity, while the nanoscale electrically conducting phase provides both bulk conductivity and local electron transfer with the electrochemically active phase. Zn Electrodeposition: Zn redox in air and water stable N-ethyl-N-methylmorpholinium bis(trifluoromethanesulfonyl)imide, [C2nmm][NTf2] is presented. Under various conditions, characterization of overpotential, kinetics and diffusion of Zn species and morphological evolution as a function of overpotential and Zn concentration are analyzed. The surface stress evolution during Zn deposition is examined where grain size and texturing play significant rolls in compressive stress generation. Morphological repeatability in the ILs led to a novel study of purity in ionic liquids where it is found that surface adsorption of residual amine and chloride from the organic synthesis affect growth characteristics. The drivers of this work are to understand the processes occurring at the electrode-electrolyte interface and with that knowledge, engineer systems yielding optimal performance. With this in mind, the design of a bulk supercapacitor electrode architecture with excellent composite specific capacitances, as well as develop conditions producing ideal Zn deposition morphologies was completed.

Description
In the first thirty years of the XX century, an old literary visual tradition was reborn in a series of new striking visual texts better known as calligrams. They were produced by some avant-garde poets such as Vicente Huidobro, José Juan Tablada, Alberto Hidalgo and Carlos Oquendo de Amat in Latin America, and Juan Larrea, Guillermo de Torre, Francisco Vighi, Luis Mosquera, and others in Spain. However, with few exceptions, the interpretation of those written drawings has caught little attention from literary critics. This research, contrasted to that of Willard Bohn's, is a contribution to the deciphering of such literary art form, designated here as the figurative visual poem. It is a proposal for its visual reading which draws from the fact that this type of text is concretely a drawing formed by written verses. As such, it can be regarded as a plastic writing, combining pictorial and verbal signs in one perceptible configuration on the page. The result of this semiotic operation is a hybrid product in which the iconic forms become symbolic and vice versa. It is in fact, an art object which should be approached as a text that can be seen as well as read. The study leads to the conclusion that Willard Bohn misreads the order in which language and image are articulated in the visual poem identified with the second order semiological system proposed by Roland Barthes, placing preeminence on language over image. This results in reading the avant-garde visual figurative poem in an ekphrastic fashion. Consequently, the role of the image in the system is left in an ambiguous realm at the time of deciphering this hybrid text. Our contribution to re-conducting this undertaking has been equally drawn from a semiotic stance taken from Louis Hjemslev that balances language and image as correlates of a semiotic function. Due to the signaling nature of both, language and figure, a visual poem becomes an iconic metaphor as well as a metaphoric icon, and moreover a self-referential sign, thus justifying its status of an autonomous art.

Description
The hagiographic comedy written by Tirso de Molina Los lagos de San Vicente (1607) presents the journey of Santa Casilda in search of the cure of an illness in her blood that affects her. Casilda rejects the medical assistance offered to her by Muslim doctors and miraculously she finds the cure in the Christian world. In this quest, the intellectual and theological evolution of the future saint in defense of the Christian faith is presented. This dissertation will study the resources that Tirso de Molina employs to show the rejection and displacement against the Islamic world represented by a series of erotic behaviors that, in the effort of dramatizing these impertinences they are characterized within a second discourse. Tirso de Molina takes advantage of the hagiographic comedy's discourse nature and the baroque's obscure literary characteristics to express his messages. This dissertation will study in detail how the combination of hagiographic theatrical elements with linguistic expressions are used to convey a subversive discourse that therefore suggests the application of queer theory as a frame of reference. As a result of this investigation it is concluded that Tirso de Molina promotes the hagiographic model and in order to contrast the triumph of the moral Catholic world over the immoral Muslim world the play writer makes references to the nefarious sin.

Description
ABSTRACT As referenced in Navajo ceremonial prayers and songs, "Saad bee hahoozhood jini," it began harmoniously with language. This dissertation examines and celebrates in new ways the meaning of language in Navajo literature. The first chapter is an introduction of this dissertation. I share my personal experiences with language, both English and Navajo, and how it has shaped me to be the person I am today as a Navajo speaker, student, educator, and professional. The second chapter contains an analysis and review of Western ideology of feminism and its place in Navajo society and a comparative study of several works written by Navajo authors, including Laura Tohe, Luci Tapahonso, and Nia Francisco, and how their creative works reflect the foundation of Navajo culture, Asdzaa Nadleehe, Changing Woman. The third chapter presents my own short fiction of Navajo characters living in today's society, a society that entails both positive and negative issues of Navajo life. These stories present realistic twenty-first century environments on the Navajo reservation. The fourth chapter consists of a short fiction written originally in the Navajo language. The story also represents the celebration of Navajo language as it thrives in today's time of tribal and cultural struggles. The sense of it being told in Navajo celebrates and preserves Navajo culture and language. The final chapter is the beginning of an oral narrative presented in written form, that of my grandmother's life story. This introduction of her story also is in itself a commemoration of language, oral Navajo language.

Description
A new challenge on the horizon is to utilize the large amounts of protein found in the atmosphere to identify different organisms from which the protein originated. Included here is work investigating the presence of identifiable patterns of different proteins collected from the air and biological samples for the purposes of remote identification. Protein patterns were generated using high performance liquid chromatography (HPLC). Patterns created could identify high-traffic and low-traffic indoor spaces. Samples were collected from the air using air pumps to draw air through a filter paper trapping particulates, including large amounts of shed protein matter. In complimentary research aerosolized biological samples were collected from various ecosystems throughout Ecuador to explore the relationship between environmental setting and aerosolized protein concentrations. In order to further enhance protein separation and produce more detailed patterns for the identification of individual organisms of interest; a novel separation device was constructed and characterized. The separation device incorporates a longitudinal gradient as well as insulating dielectrophoretic features within a single channel. This design allows for the production of stronger local field gradients along a global gradient allowing particles to enter, initially transported through the channel by electrophoresis and electroosmosis, and to be isolated according to their characteristic physical properties, including charge, polarizability, deformability, surface charge mobility, dielectric features, and local capacitance. Thus, different types of particles are simultaneously separated at different points along the channel distance given small variations of properties. The device has shown the ability to separate analytes over a large dynamic range of size, from 20 nm to 1 μm, roughly the size of proteins to the size of cells. In the study of different sized sulfate capped polystyrene particles were shown to be selectively captured as well as concentrating particles from 103 to 106 times. Qualitative capture and manipulation of β-amyloid fibrils were also shown. The results demonstrate the selective focusing ability of the technique; and it may form the foundation for a versatile tool for separating complex mixtures. Combined this work shows promise for future identification of individual organisms from aerosolized protein as well as for applications in biomedical research.

Description
Reduced space is an important theme in the works of the Marquis de Sade including his epic novel The New Justine and his pornographic performance piece Philosophy in the Bedroom including the political/social treatise "Frenchmen, yet another effort is needed if you want to be a Republic". Through out his life Sade attempted to overcome reduction of space with writing. Tragically, his writing often prolonged the reduction of his space by sending him to or keeping him in prison. It is my theory that his violent, pornographic writing style is "une écriture de surjouissance" or "a writing of over-coming". Surjouissance is my theory for Sade's method, based on textual analysis of Sade's main works, that he combines through his syntactic structure, narrative voice, and semantic themes the orgasm of the mind represented by philosophical discourse with the orgasm of the body represented textually by orgiastic scenes and the language of orgasm to reach an ultimate state of complete freedom. In the political pamphlet "Frenchmen yet another effort..."Sade attempts to set this theory of sur-jouissance, or this transcendent state reached through the combination of physical and philosophical orgasm, as the political foundation for a new republic. Does he succeed in creating a viable political formula for a sustainable republic? My argument states absolutely not. His aristocratic elitism narrows his voice. But he does propose the combination of sexual, literary, and intellectual freedoms as a possible polemic against any form of reduced space.

Description
ABSTRACT études; written for violin ensemble, which include violin duets, trios, and quartets, are less numerous than solo études.; These works rarely go by the title "étude;," and have not been the focus of much scholarly research. Ensemble études; have much to offer students, teachers and composers, however, because they add an extra dimension to the learning, teaching, and composing processes. This document establishes the value of ensemble études; in pedagogy and explores applications of the repertoire currently available. Rather than focus on violin duets, the most common form of ensemble étude;, it mainly considers works for three and four violins without accompaniment. Concentrating on the pedagogical possibilities of studying études; in a group, this document introduces creative ways that works for violin ensemble can be used as both études; and performance pieces. The first two chapters explore the history and philosophy of the violin étude; and multiple-violin works, the practice of arranging of solo études; for multiple instruments, and the benefits of group learning and cooperative learning that distinguish ensemble étude; study from solo étude; study. The third chapter is an annotated survey of works for three and four violins without accompaniment, and serves as a pedagogical guide to some of the available repertoire. Representing a wide variety of styles, techniques and levels, it illuminates an historical association between violin ensemble works and pedagogy. The fourth chapter presents an original composition by the author, titled Variations on a Scottish Folk Song: étude; for Four Violins, with an explanation of the process and techniques used to create this ensemble étude.; This work is an example of the musical and technical integration essential to étude; study, and demonstrates various compositional traits that promote cooperative learning. Ensemble études; are valuable pedagogical tools that deserve wider exposure. It is my hope that the information and ideas about ensemble études; in this paper and the individual descriptions of the works presented will increase interest in and application of violin trios and quartets at the university level.
