Synthesis And Characterization Of A New Fluorine Substituted Nonionic Dinucleoside Phosphonate Analog, 3',5'-Bis(Deoxythymidine) Difluoromethylphosphonate., Patrick Wai-Kwok Shum

Theses and Dissertations

Phosphate-modified oligodeoxyribonucleotide analogs have been extensively investigated for the sequence hybridization arrest of mRNA translation and as biochemical probes of nucleic acid-protein interaction. The goal of our research was to synthesize a new class of nonionic oligodeoxyribonucleotides which structurally closely resembled natural DNA.Our initial research concentrated on the synthesis of bis(deoxythymidine) difluoromethylphosphonate, a dinucleotide analog of 5$\sp\prime$-deoxythymidyl-3$\sp\prime$-deoxythymidine in which a CF$\sb2$H group replaces a phosphate OH. The difluoromethyl group is isosteric and isopolar to an oxygen atom. We chose to model our approach after a scheme devised for conventional phosphodiester synthesis via the protected hydroxybenzotriazole of phosphonic acid. The difluoromethylphosphonate …

The shift in importance from mostly seasonal rail/fjord traffic to an all-season automobile traffic has the potential for accelerating tourism pressures in this highly scenic area. The purpose of this study was to address possible problems and prospects of changing accessibility for tourism in the Aurland Municipality.

In order to examine tourism in the Aurland Municipality, a number of methods were used. Fieldwork was …

Race Of The Century : Guy Vs. Young, 1974 North Dakota U.S. Senate Election, Allan C. Young

Theses and Dissertations

As the 1972-1974 election cycle began, Republican incumbent Milton Young, who had served in the U.S. Senate for twenty-seven years, decided to run for another term with realistic confidence in his ability to repeat prior election victories. His initial optimism began to erode as national Republican leaders questioned his ability to defeat his apparent opponent, former North Dakota Governor William L. Guy. Results of public opinion surveys added credibility to the perception of Young's weakness. Guy saw an opportunity to achieve his long-held goal of becoming a U.S. Senator and cautiously laid the groundwork for his campaign. As the two …

Has The Small Business Administrations Minority Business Development Program Been Successful?, Rese E. Farrish Jr

Theses and Dissertations

Minorities are less likely to own a firm than their non-minority counterparts and many continue to form businesses with little growth potential. The Small Business Administration (SBA) under the Section 8(a) Minority Business Development Program is responsible for assisting small minority owned businesses in making a successful transition into the competitive marketplace. Using congressional reports, surveys, and independent reports, this study attempted to answer the question, "Has the 8(a) program been serving its purpose? Is it working?" To answer this question several problem areas were discussed. These centered in two areas, problems within the SBA and problems encountered in the …

Automatic Meshing Of Free-Form Deformation Solids, Ssuta S. Hsu

Theses and Dissertations

Development of computer models and subsequent finite element analysis, are important aspects of modern engineering design. In this process, the geometry creation and finite element analysis software are well developed; however, the process of discretizing a geometry into a proper finite element model is time consuming and tedious. The work presented here uses the free-form deformation method to create smooth solid models, and invokes a solid subdivision and transition method to generate the hexahedron finite elements. The combination of these two techniques provides an automatic mesh generator that is easy to use, creates acceptable hexahedron elements for finite element analysis, …

A series of 6-substituted purine nucleosides have been made which may exhibit a considerable range of biological activity.Project 2 concerned the synthesis of nucleotide-insertanes as probes for transport; Part A specifically was related to macrocyclic ethers. Crown ethers were designed which, in addition to their intrinsic structural interest, were anticipated to be useful as synthetic intermediates, and as carriers for the transport of nucleotides through cell membranes. It was sought …

The Synthesis Of Oligo- And Polynaphthyls And Their Reactions In Molten Salts., Jeffery Howard Banning

Theses and Dissertations

There have been several recent attempts to synthesize a one-dimensional graphite-like polymer, namely poly(peri-naphthalene) (PPN). All of these approaches involved pyrolysis of a substituted perylene monomer to yield a polymer that exhibited characteristics not unlike those expected for PPN. The process of going from a monomer directly to an intractable polymer raises questions regarding processibility. A potential means to avoid the question is to synthesize a soluble/processible precursor polymer and subsequently convert this polymer to the desired PPN. This is the goal of the research reported herein.To successfully approach such a project, studies with appropriate model compounds were deemed necessary. …

A Hermeneutic Of Sacred Texts: Historicism, Revisionism, Positivism, And The Bible And Book Of Mormon, Alan Goff

Theses and Dissertations

As methods by which texts are to be understood, positivism and historicism have a long tradition and continue to exert wide influence in all academic disciplines. Other approaches to textual concerns have recently emerged to challenge the dominance of these two approaches. Foremost among these new approaches are hermeneutics and deconstruction. Both of the latter approaches recognize that interpretation is inescapable. The latter challenges even the possibility of determinate meaning. A theoretical discussion of historicism and positivism uncovers questionable and troublesome difficulties. Hermeneutics in its conservative or radical variations overcomes the difficulties of interpretation that positivism and historicism can't explain. …

Competitive Fire: An Historical Descriptive Analysis Of Adherence To Traditional Journalistic Tenets In Television News Coverage Of The Mark Hofmann Salt Lake City Bombings, B. William Silcock

Theses and Dissertations

Television news contains factors of time constraints and deadlines that add pressures to the underlying rules of objectivity, fairness, and bias. This study seeks to determine if the elements of "responsible journalism" dissipate in television news coverage of a highly significant, developing news story. In other words, how well do the rules hold up under pressure? The momentous story selected for observation was the Mark Hofmann bombings in Salt Lake City, Utah. The focus centered on the coverage by local stations rather than the network television news operations.
