The Phenomenon Of Superconductivity: A Feasibility Study For Business, Julian E. Thrash

Theses and Dissertations

Why should American industries risk future viability in order to invest in superconductivity? This independent study explored this question in order to reach a more informed conclusion. The tendency for American firms is to plan for short-term profits at the expense of research and development programs. By cutting research and development funds, firms are losing a proprietary knowledge base necessary to compete in a dynamic environment. A loss of proprietary knowledge in the field of science, severely handicaps a firm in its drive for success.

The information presented in this study is an attempt to give the average corporate executive …

Theses and Dissertations

The purpose of this study was to determine the perceived value of principal transfer by examining and describing superintendent and principal perceptions of school division transfer processes and of anticipated and actual succession effects. Five superintendents and ten principals--the superintendent, one elementary principal, and one secondary principal from each of five of the ten metropolitan school divisions located in Winnipeg, Manitoba--were interviewed by the researcher. The superintendents described one of two general types of transfer used in moving principals--a long-term career/organizational development process and a short-term vacancy chain process. The principals reacted to these descriptions and gave their perceptions of …

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 …

Edith Irvine: Her Life And Photography, Wilma Marie Plunkett

Theses and Dissertations

ln mid-1988, Brigham Young University received a high-quality collection of photographic glass plates made by Edith Irvine at the tum of the century. The plates, her camera and other photographic equipment, and miscellaneous publications were donated to BYU by her nephew, Jim Irvine.

When the plates arrived and the Archives Photolab had them proofed, we realized thal not only were the San Francisco earthquake/ fire and other areas of California history recorded, but we had, in fact, the work of an outstanding photographer. As we compared the proofs with the work of other photographers who handled similar subjects, we called …

Aspects Of Mammalian Predation On Upland Nesting Waterfowl In Central North Dakota, John Thompson Trevor

Theses and Dissertations

The impact of mammalian predation on upland nesting waterfowl was studied in central- North Dakota during the summers of 1987 and 1988. Survival of artificial nests was examined in relation to nest density, vegetation cover, distance from roads, active predator dens, and other artificial nests in a plot. Survival of artificial nests was also compared between an area with predator control and one without predator control.

Artificial waterfowl nests located in high density plots had a significantly lower probability of survival than nests located in low density plots. Although there were significant differences in vegetation height and density between years, …

Why Small Businesses Fail, William W. Schlepuetz

Theses and Dissertations

Small businesses fail at an alarmingly high rate. The seriousness of this is underscored by the impact of small business on the economy. Small business accounts for 45% of the U. s. gross national product and employs nearly 60% of the work force.

External factors such as the environment are responsible for some failures. Internal causes of failure parallel all functional areas of the business: however, approximately 90 percent of all small business failures are related to management incompetence or inexperience.

Two major failings of the incompetent or inexperienced manager are the lack of a business plan and poor managerial …

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, …
