The Birth Of Sacrifice: Iconographic Metaphors For Spiritual Rebirth In Master Matthias' Isenheim Altarpiece, Katherine Lena Anderson Dec 2006

The Birth Of Sacrifice: Iconographic Metaphors For Spiritual Rebirth In Master Matthias' Isenheim Altarpiece, Katherine Lena Anderson

Theses and Dissertations

While little is known concerning the events surrounding the commission of the Isenheim Altarpiece or of the artist known to us as Master Matthias Grünewald, much can be ascertained about the message of the Altarpiece through careful study of the socio-historical-religious context from which the work was commissioned and iconographic analysis of the images portrayed by Master Matthias. This thesis explores iconographic metaphors for birth and sacrifice, metaphors which work to create a theological dialogue about Christian redemption within the nine painted panels and the underlying sculpture that makes up the Isenheim Altarpiece. First, we will address the panels in …

Large 3-D Deflection And Force Analysis Of Lateral Torsional Buckled Beams, Robert Parley Chase Dec 2006

Large 3-D Deflection And Force Analysis Of Lateral Torsional Buckled Beams, Robert Parley Chase

Theses and Dissertations

This thesis presents research on the force and deflection behavior of beams with rectangular cross-sections undergoing lateral torsional buckling. The large 3-D deflection path of buckling beam tips was closely approximated by circular arcs in two planes. A new chain algorithm element was created from pseudo-rigid-body segments and used in a chain calculation that accurately predicted the force deflection relationship of beams with large 3-D deflections.

Forage Adaptability Trials For Forage And Seed Production In Bolivia; Effect Of 5 Herbicides On 7 Native Utah Forbs, Joshua C. Voss Dec 2006

Forage Adaptability Trials For Forage And Seed Production In Bolivia; Effect Of 5 Herbicides On 7 Native Utah Forbs, Joshua C. Voss

Theses and Dissertations

The harsh environmental and poor economic conditions of the Bolivian Altiplano require intervention to assist many of those that live there to become economically self-sufficient. We attempted to find introduced dry season reserve forage grasses that could produce enough biomass to be useful as feed for livestock, and that could also produce enough seed to distribute to farmers. While some of the grasses produced reasonable amounts of biomass, none produced seed in quantities that would be even close to being economically viable. The most likely cause of this is that the timing of resources that the grasses need to flower …

Life Data Analysis Of Repairable Systems: A Case Study On Brigham Young University Media Rooms, Stephen Oluaku Manortey Dec 2006

Life Data Analysis Of Repairable Systems: A Case Study On Brigham Young University Media Rooms, Stephen Oluaku Manortey

Theses and Dissertations

It is an undisputable fact that most systems, upon consistence usage are bound to fail in the performance of their intended functions at a point in time. When this occurs, various strategies are set in place to restore them back to a satisfactory performance. This may include replacing the failed component with a new one, swapping parts, resetting adjustable parts to mention but a few. Any such system is referred to as a repairable system. There is the need to study these systems and use statistical models to predict their failing time and be able to set modalities in place …

Synthesis And Optical Properties Of Four Oligothiophene-Ruthenium Complexes And Synthesis Of A Bidentate Ligand For C-F Bond Activation, Joseph S. Bair Dec 2006

Synthesis And Optical Properties Of Four Oligothiophene-Ruthenium Complexes And Synthesis Of A Bidentate Ligand For C-F Bond Activation, Joseph S. Bair

Theses and Dissertations

Photovoltaic cells and fluorescence sensing are two important areas of research in chemistry. The combination of photon-activated electron donors with electron acceptors provides a strong platform for the study of optical devices. A series of four oligothiophene-ruthenium complexes has been synthesized. Variation in oligothiophene length and bipyridine substitution allowed comparison of these variables on electronic properties. The longer oligothiophenes display lower energy absorption and emission compared to the shorter ones. Aromatic conjugation appears more complete with para-, rather than meta-, substitution. Oligothiophenes and Ru(bpy)32+ are highly fluorescent individually, but fluorescence is quenched when connected. Bonds of carbon to fluorine are …

The Role Of Wnt Signaling In Development Of The Ophthalmic Trigeminal Placode., Rhonda Nicole Lassiter Dec 2006

The Role Of Wnt Signaling In Development Of The Ophthalmic Trigeminal Placode., Rhonda Nicole Lassiter

Theses and Dissertations

Cranial placodes are ectodermal regions that contribute extensively to the vertebrate peripheral nervous system. The development of the ophthalmic trigeminal (opV) placode, which gives rise only to sensory neurons of the ophthalmic lobe of the trigeminal ganglion, is a well-studied model of sensory neuron development. While key differentiation processes have been characterized at the tissue and cellular levels, the molecules governing opV placode development have not been well described. This study identifies the canonical Wnt signaling pathway as a regulator of opV trigeminal placode development. Introducing dominant-negative TCF and dominant-active β-catenin expression constructs by in ovo electroporation, we have manipulated …

Development Of Polymer Monoliths For The Analysis Of Peptides And Proteins, Binghe Gu Dec 2006

Development Of Polymer Monoliths For The Analysis Of Peptides And Proteins, Binghe Gu

Theses and Dissertations

Several novel polymer monoliths for the analysis of peptides and proteins were synthesized using polyethylene glycol diacrylate (PEGDA) as crosslinker. Photo-initiated copolymerization of polyethylene glycol methyl ether acrylate and PEGDA yielded an inert monolith that could be used for size exclusion liquid chromatography of peptides and proteins. This macroscopically uniform monolith did not shrink or swell in either water or tetrahydrofuran. More importantly, it was found to resist adsorption of both acidic and basic proteins in aqueous buffer without any organic solvent additives. A strong cation-exchange polymer monolith was synthesized by copolymerization of 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and PEGDA. A ternary …

Using Social Network Analysis To Investigate Potential Bias In Editorial Peer Review In Core Journals Of Comparative/International Education, Biao Cheng Dec 2006

Using Social Network Analysis To Investigate Potential Bias In Editorial Peer Review In Core Journals Of Comparative/International Education, Biao Cheng

Theses and Dissertations

This study explores potential bias in the editorial peer-review system within the context of the field of comparative and international education. Assuming the role as “Guardian of Science” and “social status judge” (Zuckerman & Merton, 1971), peer-review, the quality control system of science, directly affects the growth of science, scientists' academic career and their institutions. The very basic tenet of the peer review system is its assumed objectivity. Bias in editorial peer review process, however, is inevitable. The constitution of the blind peer review mechanism is itself a simply undeniable acknowledgement of that fact. Therefore, this study investigated potential peer-review …

Computationally Modeling The Effects Of Surface Roughness On Soft X-Ray Multilayer Reflectors, Jedediah Edward Jensen Johnson Dec 2006

Computationally Modeling The Effects Of Surface Roughness On Soft X-Ray Multilayer Reflectors, Jedediah Edward Jensen Johnson

Theses and Dissertations

Electromagnetic scattering from a rough two dimensional homogeneous scatterer has been computationally modeled. The scatterer is intended to simulate reflection from a two interface multilayer. The rough scatterer was created from Gaussian random points centered about an ideal interface. The points were connected with a third order spline interpolant which accounts for correlation between neighboring surface atoms. The scalar electric field integral equation (EFIE) and magnetic field integral equation (MFIE) were solved using the Nystrom method to obtain the reflected intensity as a function of observation angle. Verification of the accuracy of the code was obtained by means of comparison …

Generating Paraphrases With Greater Variation Using Syntactic Phrases, Rebecca Diane Madsen Dec 2006

Generating Paraphrases With Greater Variation Using Syntactic Phrases, Rebecca Diane Madsen

Theses and Dissertations

Given a sentence, a paraphrase generation system produces a sentence that says the same thing but usually in a different way. The paraphrase generation problem can be formulated in the machine translation paradigm; instead of translation of English to a foreign language, the system translates an English sentence (for example) to another English sentence. Quirk et al. (2004) demonstrated this approach to generate almost 90% acceptable paraphrases. However, most of the sentences had little variation from the original input sentence. Leveraging syntactic information, this thesis project presents an approach that successfully generated more varied paraphrase sentences than the approach of …

Information Infrastructure For Integrated Ecohydraulic And Water Resources Modeling And Assessment, R. Wallace, K. Pathak, M. Fife, Norman L. Jones, J. P. Holland, D. Stuart, J. Harris, C. Butler, D. R. Richards Dec 2006

Information Infrastructure For Integrated Ecohydraulic And Water Resources Modeling And Assessment, R. Wallace, K. Pathak, M. Fife, Norman L. Jones, J. P. Holland, D. Stuart, J. Harris, C. Butler, D. R. Richards

Faculty Publications

Watershed management increasingly requires ecohydraulic modeling and assessment within a regional context, rather than on a project-by-project basis. Such holistic modeling and assessment require evaluation capabilities across multiple temporal and spatial scales. Thus, modeling and assessment tools must be integrated in a scientifically and computationally effective infrastructure. The US Army Engineer Research and Development Center, in concert with the Hydrologic Engineering Center and its academic partners, including Brigham Young University, is establishing a comprehensive set of hydroinformatics modeling and assessment tools for ecohydraulic and water resources management applications, all linked based on a common data and information infrastructure.

The Smith-Mundt Act's Ban On Domestic Propaganda: An Analysis Of The Cold War Statute Limiting Access To Public Diplomacy, Edward L. Carter, Allen W. Palmer Dec 2006

The Smith-Mundt Act's Ban On Domestic Propaganda: An Analysis Of The Cold War Statute Limiting Access To Public Diplomacy, Edward L. Carter, Allen W. Palmer

Faculty Publications

For more than fifty years, the U.S. Code has authorized the federal government to disseminate messages about America to international audiences. For at least thirty years, federal law has also prohibited those international propaganda messages from being disseminated within the United States. Given the realities of the acceleration and dispersion of information flow across international borders in the twenty-first century, a ban on dissemination of information that is tied to geographic boundaries raises both practical and policy issues. The domestic dissemination ban may have outlived its usefulness and relevance. Further, futile enforcement of the statute contradicts general U.S. policy promoting …

Development Of Methods For The Study Of Phosphoproteins, Zhaoyuan Chen Dec 2006

Development Of Methods For The Study Of Phosphoproteins, Zhaoyuan Chen

Theses and Dissertations

Characterization of phosphoproteins-including detection, identification of phosphoproteins and identification of phosphorylation sites-is mostly done with radiolabeling and proteomic techniques. Three main topics related to phosphoprotein characterization are included in this dissertation. First, large-scale characterization of the CHO (Chinese hamster ovary) cell phosphoproteome was done using two dimensional gel electrophoresis (2DE) separation, visualization of phosphoproteins by radiolabeling or a phosphoprotein specific dye, followed by MALDI-TOF identification. Because radiolabeling of phosphoproteins is very sensitive and straightforward to quantify, such analysis can give a clear picture of the relative phosphosphorylation of proteins present in a sample. But there are also limitations to this …

Once Upon A Time In A Single-Parent Family: Father And Daughter Relationships In Disney's The Little Mermaid And Beauty And The Beast, Ashli A. Sharp Dec 2006

Once Upon A Time In A Single-Parent Family: Father And Daughter Relationships In Disney's The Little Mermaid And Beauty And The Beast, Ashli A. Sharp

Theses and Dissertations

Fairy tales are adapted to fit the needs of each generation, reflecting the unique challenges of that society. In the 1980s and 1990s of the United States, issues of what constituted a family circulated as divorce increased and fatherhood was debated. At this time, Disney released two animated films featuring a father and daughter: The Little Mermaid and Beauty and the Beast. Both films are adaptations of fairy tales, and they incorporate changes that specifically reflect concerns of the United States in the late-twentieth century. In the original narrative of "The Little Mermaid" the heroine is primarily raised by her …

The Relationship Between The Minimal Rank Of A Tree And The Rank-Spreads Of The Vertices And Edges, John Henry Sinkovic Dec 2006

The Relationship Between The Minimal Rank Of A Tree And The Rank-Spreads Of The Vertices And Edges, John Henry Sinkovic

Theses and Dissertations

Let F be a field, G = (V,E) be an undirected graph on n vertices, and let S(F,G) be the set of all symmetric n × n matrices whose nonzero off-diagonal entries occur in exactly the positions corresponding to the edges of G. Let mr(F,G)be the minimum rank over all matrices in S(F,G). We give a field independent proof of a well-known result that for a tree the sum of its path cover number and minimal rank is equal to the number of vertices in the tree. The rank-spread of a vertex v of G is the difference between the …

Defining A Model For Tool Consumption Rate On Asphalt Reclamation Machines, Matthew H. Taylor Nov 2006

Defining A Model For Tool Consumption Rate On Asphalt Reclamation Machines, Matthew H. Taylor

Theses and Dissertations

Asphalt and concrete reclamation machines are used to cut roadways when a repair is required. The performance of these machines can affect the quality of road repairs, and cost/profitability for both contractors and governments. We believe that several performance characteristics in reclamation machines are governed by the placement and pattern of cutting picks on the cutter head. Previous studies, focused on mining and excavation applications, have shown strong correlation between placement and wear. The following study employs a screening experiment (observational study) to find significant contributors to tool wear, in applications of asphalt milling or reclamation. We have found that …

Predictors Of Change In Health Care Use After Marital And Family Therapy, Scott H. Payne Nov 2006

Predictors Of Change In Health Care Use After Marital And Family Therapy, Scott H. Payne

Theses and Dissertations

The cost of health care continues to increase. Based on the biopsychosocial model of heath care, it has been shown that the treatment of psychological and social problems can have a cost offset effect on the cost of medical care. While this offset effect has been shown in an MFT population, there are no known studies that have looked at predictors of the change in medical use by those that receive marital and family therapy. This study looked at psychological and social measures of individuals who received marital and family therapy. These measures were evaluated based on the change from …

The Influence Of Membrane Lipid Order On Cell Shape And Microvesiculation In Human Erythrocytes, Laurie Jackson Gonzalez Nov 2006

The Influence Of Membrane Lipid Order On Cell Shape And Microvesiculation In Human Erythrocytes, Laurie Jackson Gonzalez

Theses and Dissertations

Exposure of human erythrocytes to elevated intracellular calcium causes alterations in cell shape and stimulates shedding of the cell membrane in the form of microvesicles. We hypothesized that both the shape transition and microvesiculation are influenced by microscopic membrane physical properties such as lipid order. To test this hypothesis, membrane properties were manipulated by varying the experimental temperature, membrane cholesterol content, and the internal ionic environment. Changes in membrane order were assessed using steady-state fluorescence spectroscopy with an environment-sensitive probe, laurdan. Our observations led us to the following conclusions: 1) the modest temperature dependence of membrane structure observed with laurdan …

Contour Encoded Compression And Transmission, Christopher B. Nelson Nov 2006

Contour Encoded Compression And Transmission, Christopher B. Nelson

Theses and Dissertations

As the need for digital libraries, especially genealogical libraries, continues to rise, the need for efficient document image compression is becoming more and more apparent. In addition, because many digital library users access them from dial-up Internet connections, efficient strategies for compression and progressive transmission become essential to facilitate browsing operations. To meet this need, we developed a novel method for representing document images in a parametric form. Like other “hybrid" image compression operations, the Contour Encoded Compression and Transmission (CECAT) system first divides images into foreground and background layers. The emphasis of this thesis revolves around improving the compression …

Fgf4 And Wnt5a/Pcp Signaling Promote Limb Outgrowth By Polarizing Limb Mesenchyme, Keri Lynn Low Nov 2006

Fgf4 And Wnt5a/Pcp Signaling Promote Limb Outgrowth By Polarizing Limb Mesenchyme, Keri Lynn Low

Theses and Dissertations

The focus of this study was to elucidate the molecular and cellular mechanisms whereby fibroblast growth factors (FGFs) mediate outgrowth of the limb. Specifically, we examined the epistatic relationship between FGF and Wnt/Planar cell polarity (PCP) signaling in establishing cell polarity as a mechanism for outgrowth. By implanting beads into embryonic limbs and lateral plate mesoderm, we established that FGF activates Wnt5a in a gradient fashion. Once it was established that Wnt5a was expressed at the right time and place to turn on PCP signaling, we investigated the ability of Wnt5a to influence cell migration and/or cell polarity. Our analysis …
