The characterization of new benzimidazole fungicides /

Extensive studies have been initiated to generate enough data to register the methyl homologue (MBC-MIC, see List of Abbreviations, page 14) of benomyl (MBC-BIC) as a commercial product through a joint effort between the federal government and Canadian industry. The objective of this study, as part of the whole project, was to generate fundamental data on the physical properties of the series of benomyl homologues (MBC-MIC, MBC-EIC, MBC-PIC and MBC-BIC). These data include the half lives of these compounds in water at the pH range from 2 to 12; they ranged from 0.7 to 10. 1 hours. Standard solutions of these compounds in concentrated acid were found to be stable for at least two weeks, and in the case of MBC-MIC it was stable at least 1 month. Another major goal of this study was to determine the solubility of each compound in water at different pHs in the range of 1 to 12. The solubility of the compounds ranged from 0.6 jig/mL to 396 fig/mL. In addition, it was possible to prepare stable stock solutions at concentrations > 1 000 |ig/mL in concentrated nitric acid. Several aspects of analytical methods have been improved to accurately assess the solubility and rate of degradation of benomyl and its homologues in alkaline conditions. The determination of melting points was attempted but all compounds decomposed before melting.To complement the studies of the benomyl homologue series attempts were made to explore the presence of any relationships between the structures of the compounds and their properties. Although there were some exceptions, the compound's solubility decreased and half life increased as the molecular size increased from the methyl to the butyl analogue.

Melting the matrices : structure, anti-structure, and the emerging conversation /

This thesis investigates two cases of Christian churches, which as a part of their mission seek to accommodate people who would otherwise not be interested in church. One of these communities consider themselves a part of the global 'emerging church' movement, and the other does not. I argue that both communities are employing what I call 'de-compartmentalization' strategy in order to adopt a pragmatic relationship with social and political issues. Furthermore I discuss the case of the emerging church community as an example of 'paraliminal community '; a concept I develop from the work of Victor Turner and Arnold van Gennep.

Molecular dynamics calculation of mean square displacement in alkali metals and rare gas solids and comparison with lattice dynamics

Molec ul ar dynamics calculations of the mean sq ua re displacement have been carried out for the alkali metals Na, K and Cs and for an fcc nearest neighbour Lennard-Jones model applicable to rare gas solids. The computations for the alkalis were done for several temperatures for temperature vol ume a swell as for the the ze r 0 pressure ze ro zero pressure volume corresponding to each temperature. In the fcc case, results were obtained for a wide range of both the temperature and density. Lattice dynamics calculations of the harmonic and the lowe s t order anharmonic (cubic and quartic) contributions to the mean square displacement were performed for the same potential models as in the molecular dynamics calculations. The Brillouin zone sums arising in the harmonic and the quartic terms were computed for very large numbers of points in q-space, and were extrapolated to obtain results ful converged with respect to the number of points in the Brillouin zone.An excellent agreement between the lattice dynamics results was observed molecular dynamics and in the case of all the alkali metals, e~ept for the zero pressure case of CSt where the difference is about 15 % near the melting temperature. It was concluded that for the alkalis, the lowest order perturbation theory works well even at temperat ures close to the melting temperat ure. For the fcc nearest neighbour model it was found that the number of particles (256) used for the molecular dynamics calculations, produces a result which is somewhere between 10 and 20 % smaller than the value converged with respect to the number of particles. However, the general temperature dependence of the mean square displacement is the same in molecular dynamics and lattice dynamics for all temperatures at the highest densities examined, while at higher volumes and high temperatures the results diverge. This indicates the importance of the higher order (eg. ~* ) perturbation theory contributions in these cases.
