Gutenberg’s effects on universities

This article considers the effects on universities of Gutenberg’s invention of printing. It considers four major effects: the gradual displacement of Latin as the language of scholarship with vernacular languages, the expansion and eventual opening of libraries, major changes to curriculum, and major changes to pedagogy including lectures. The paper does not find that the ubiquity of books changed the role of university teachers as was proposed in the late fifteenth century. The paper also considers a fifth change: the eventual replacement of oral disputations with written examinations as the main form of assessment for admission to a degree. While this was radical, it owed little to the direct effects of printing. The paper concludes with brief observations on the implications of the earlier information revolution for understanding the effects on universities of the current information revolution.     

印染废水中COD的快速测定

本文将微波消解和光度法相结合,来测定印染废水中的COD。该法无汞、无银盐,快速简便,对于氯离子浓度较低的印染废水水样,测定结果可满足印染废水处理监控的需要,具有良好的实用价值。
