(4+2)-Cycloaddition Reactions of Ketenes; Pyranones

Description: This study deals with the (4+2)-cycloaddition reactions of 4-π electron compounds with ketenes. Chloroketenes were generated in situ from the corresponding chlorinated acid chlorides in the presence of the ketenophiles. Chloro-, dichloro- and diphenylketenes reacted with 1-methoxy-3-trimethylsiloxy-l,3-butadiene, and 2,4-bis(trimethylsiloxy)-1,3-pentadiene to yield the corresponding dihydropyrans. The dihydropyrans yielded substituted 4-pyranones on hydrolysis.

2D and 3D Fabrication Devices: Can They Improve Spatial Reasoning Skills in Children?

Description: The purpose of this study is to evaluate the potential benefit of two hours of activities involving 2D and 3D fabricators on the spatial reasoning skills of children in Grades 4 and 5, ages 9 to 10, from a private school in Southeast Texas. Can the introduction to hands-on activities with products created with these devices and learning about how these devices operate improve spatial reasoning skills? The research also evaluates the use of the Shapes Test as a valid measure of the spatial reaso… more

Ab Initio and Density Functional Investigation of the Conformer Manifold of Melatonin and a Proposal for a Simple Dft-based Diagnostic for Nondynamical Correlation

Description: In this work we address two problems in computational chemistry relevant to biomolecular modeling. In the first project, we consider the conformer space of melatonin as a a representative example of “real-life” flexible biomolecules. Geometries for all 52 unique conformers are optimized using spin-component scaled MP2, and then relative energies are obtained at the CCSD (T) level near the complete basis set limit. These are then used to validate a variety of DFT methods with and without empiric… more

Absalom, Absalom! A Study of Structure

Description: The conclusion drawn from this study is that the arrangement of material in Absalom, Absalom! is unified and purposeful. The structure evokes that despair that is the common denominator of mankind. It reveals both the bond between men and the separation of men; and though some of the most dramatic episodes in the novel picture the union of men in brotherly love, most of the material and certainly the arrangement of the material emphasize the estrangement of men. In addition, by juxtaposing chap… more

The Abuse of Confidence as a Major Theme in the Novels of Henry James

Description: All of the aforementioned factors--love, money, the abuse of confidence, the guilt growing out of it, the response of the victim--contribute to the moral view constantly evolving towards an ultimate statement in the three novels of James's maturity. This thesis will attempt to explicate in full that statement. For James's theme of abuse of confidence, together with all of its elements, was in itself only the vehicle of a finely attuned moral awareness.

Academic Achievement and the Ability of Post-Secondary Students to Read Assigned Materials

Description: This study provides a rationale for adopting course materials. It demonstrates the relationship between ability to read assigned materials and academic achievement, and that selection of materials creates two groups having different probabilities of success. The sample was selected from a population of all students enrolled in Principles of Economics courses at North Texas State University in the spring semester of 1986. The Nelson-Denny Reading Test was used to determine reading ability. Assig… more
