Tracing T. S. Eliot's Spirit

Abstract

T. S. Eliot's lifelong quest for a world of the spirit is the theme of this book by leading Eliot scholar A. David Moody. The first four essays in the collection map Eliot's spiritual geography: the American taproot of his poetry, his profound engagement with the philosophy and religion of India, his near and yet detached relations with England, and his problematic cultivation of a European mind. At the centre of the collection is a study of the Latin poem Pervigilium Veneris, a fragment of which figures enigmatically in the concluding lines of The Waste Land. The third part of the collection is a set of five investigations of Eliot's poems, dealing particularly with The Waste Land, Ash Wednesday and Four Quartets, and attending to how they express and shape what he called 'the deeper, unnamed feelings which form the substratum of our being'.

Lipase catalysed kinetic resolutions of 3-aryl alkanoic acids

“…With the bulkier 3-alkyl substituents, chromatography was less effective. In practice the ester was recovered first by heptane extraction of the biotransformation mixture, then subsequent acidification and extraction with ethyl acetate provided the acids (R)-1b and (S)-1c-d. Each of the products were characterised by 1 H NMR and chiral HPLC. …”

“…34 Purification by column chromatography using hexane/ethyl acetate as eluant (gradient elution 10-40% ethyl acetate) gave ester (R)-3f (105 mg, 22%) as a yellow oil -24.40 (c 1.0, CHCl 3 ), 94% ee and acid (S)-1f (107 mg, 26%) as a clear oil +32.32 (c 0.622, CHCl 3 ), ≥99% ee. 1 H NMR spectra were identical to the racemic materials previously prepared.…”

“…[1][2][3][4][5][6][7][8][9][10][11] Hydrolases are excellent biocatalysts, combining wide substrate specificity with high regio-and enantioselectivity enabling the resolution of organic substrates with superb efficiency and selectivity. [12][13][14] Furthermore, hydrolases do not require the use of labile co-factors, can be recycled, can be used in both free or immobilised form and are effective under mild, environmentally benign conditions and are biodegradable.…”

“…The aqueous layer was extracted with diethyl ether (3 x 5 mL) and the combined organic extracts were filtered through celite and concentrated under reduced pressure. The sample was analysed by 1 H NMR spectroscopy, reconcentrated and dissolved in a mixture of hexane:iso-propyl alcohol (HPLC grade) and enantioselectivity determined by chiral HPLC. The results of the screen are summarised in the appropriate Tables 1-10.…”

Linear algebra algorithms as dynamical systems

“…Alternatively, since all local charts of a Lie group can be obtained by translation, we can restrict ourselves to the local charts. In particular, it suffices to consider the "local" representation of f at y n , 86) where L z (y) = zy with a fixed z ∈ G. This becomes a classical algebraic equation in the Euclidean space. The Newton iteration involves the steps of solving the equation, df vn (u n ) +f (v n ) = 0, (8.87) for u n , where v n is the local parametrization, i.e., logarithm of y n , updating over the linear space by v n+1 = v n + u n , and finally advancing to the new iterate on the manifold G by defining,…”
