Baird, a British television pioneer, experimented with video recording on gramophone discs in the late 1920s. McLean (a consultant) has restored the surviving "Phonovision" discs and, using computer techniques reminiscent of an archaeological dig, has revealed the images on the discs and uncovered details of how the recordings were made. McLean also restored amateur recordings of the BBC's 30-line Television Services (1932-1935), providing a glimpse at what viewers were then watching. This book helps explain this period in television history. Illustrated with historic photographs, it sheds light on the achievements of Baird, the development of video recording, and the definition and invention of television itself. c. Book News Inc.

Impurity profiling is the common name of a group of analytical activities, the aim of which is the detection, identification/structure elucidation and quantitative determination of organic and inorganic impurities, as well as residual solvents in bulk drugs and pharmaceutical formulations. Since this is the best way to characterise the quality and stability of bulk drugs and pharmaceutical formulations, this is the core activity in modern drug analysis.Due to the very rapid development of the analytical methodologies available for this purpose and the similarly rapid increase of the demands as regards the purity of drugs it is an important task to give a summary of the problems and the vario...
