    Boundary layer resolution in hierarchical plate modelling (1995)
    Chichester, West Sussex : Wiley-Blackwell
    Mathematical Methods in the Applied Sciences 18 (1995), S. 345-370

    Notes: The dimensional reduction of an elliptic model boundary value problem on a thin, plate-like domain of thickness 2d is analysed. A class of lower-dimensional models with variable model orders in the interior and near the boundary of the plate is investigated and it is shown that for a sufficiently large model order in a O(d∣ln d∣)-neighbourhood of the edge the hierarchical models compensate for the boundary layers of the exact solution - in the sense that their asymptotic rate of convergence as d → 0 is the same as the optimal one for compatible, layer-free solutions.

    Notes: A broad study of the 59Co NMR of cobalt(III) porphyrin complexes with axial amine ligands in a variety of solvents is reported. The data are presented in tabular form, as are the numerical correlations of chemical shift, δ, and line width, ω1/2, using the Kamlet-Taft equation. The dependence of δ and ω1/2 on ligand substituents is discussed. Solvent data, including mixed solvent results, indicate that general factors such as acidity, basicity, polarity and hydrogen-bonding capability are important, as are the specific nature of the functional groups on the ligands and the solvent.
