Re-Visiting Sylvia Townsend Warner

Sylvia Townsend Warner was born in 1893 in Harrow and died in Dorset in 1978. Her writing career was both productive and diverse, spanning poems, short stories, novels, music reviews, a biography, translations of Proust, and a guide to Somerset. But this list, impressive as it is, does not do justice to the idiosyncrasy and heterogeneity of her work. While she is well known mostly for the seven novels she published, those works are all radically different in style and content. Indeed, Townsend Warner's singularity has, it could be argued, made it difficult to place her in the various fields and sub-fields of 20th-century literary studies. She shares as many similarities as differences with the high modernists who dominated the literary landscape of the interwar period. Likewise she fits, yet also resists, the more recent formulations of intermodernist and middlebrow scholarship that have attempted to interrogate and expand the horizons of mid-20th century literature.

Static and dynamic degradation of sintered calcium phosphate ceramics

The chemical compositions of calcium phosphate materials are similar to that of bone making them very attractive for use in the repair of critical size bone defects. The bioresorption of calcium phosphate occurs principally by dissolution. To determine the impact of composition and flow conditions on dissolution rates, calcium phosphate tablets were prepared by slip casting of ceramic slips with different ratios of hydroxyapatite (HA) and ß-tricalcium phosphate (ß-TCP). Dissolution was evaluated at pH4 using both a static and dynamic flow regime. Both the composition of the HA:ß-TCP tablet and flow regime noticeably influenced the rate of dissolution; the 50:50 HA:ß-TCP composition demonstrating the greatest level of dissolution, and, exposure of the ceramic specimens to dynamic conditions producing the highest rate of dissolution. Understanding the impact of phase composition and flow condition with respect to the dissolution of calcium phosphate will aid in the development and improvement of materials for bone substitution.
