    Includes bibliographical references (pages 163-167).The linear solvation energy relationships (LSER) model proposed by Kamlet, Abraham, and Taft allows the prediction of a variety of solubility interactions based on a set of descriptors found in this equation: [special characters omitted] The terms on the right side of the equation represent different interactions of the stationary phase (subscript 1) with the solute (subscript 2). GC stationary phases can be characterized by determining these coefficients to quantify the ability of the solvent to engage in specific interactions. Once these coefficients have been determined, a correlation between the structure of the stationary phase and the coefficient values can be established. Information obtained can be used to predict solubility relationships for stationary phases that have never been characterized. The ultimate goal of this project is to develop predictive models for solubility of materials based on structural descriptors such as molecular connectivity indexes. Stationary phases with functional groups containing third quantum-level elements, such as sulfur and phosphorus, are underrepresented in current databases. Several of these compounds were analyzed by inverse gas-liquid chromatography (GLC) to find their LSER coefficients. Both experimentally obtained and previously determined coefficients were correlated with calculated polarizability, dipole moment, HOMO/LUMO energy levels, and hydrogen bond acceptor capability. Quantitative structure-solubility relationships (QSSR), correlating molecular connectivity or combinations of connectivity with other structural descriptors to LSER coefficients, yielded promising relationships. Alternative methods for calculation of phosphorus connectivity indices were developed to better describe the contributions of inner shell and valence electrons to chemical and physical properties. Modified connectivity values gave improved correlation with some LSER coefficients and were used to develop similar QSSRs.Ph.D. (Doctor of Philosophy

    Hercules and the twelve labors : a graphic novel : an honors thesis (HONRS 499)

    No full text
    The focus of this thesis is on the actual twelve labors of Hercules (a.k.a. Heracles). Unfortunately, time constraints prevented a more in-depth illustration of Hercules' life before and after these tasks. However, this portrayal of the Hercules story creates a very visual account of what is probably the most well known story of Greek myth. In this manner, it is similar to the "Classics Illustrated" series of comic books that have promoted the reading of classic literature by translating them into comic book form. Like "Classics Illustrated," this story holds true to the original--unlike more recent incarnations of Hercules that have modified the story to make it more marketable and suitable for younger audiences. This thesis is meant to provide a more accurate account of the myth rather than the overly commercial views now in circulation.Thesis (B.?.)Honors Colleg
