We describe a method for identifying semiconductor radiation detector materials based on the mobility of internally generated electrons and holes. It was designed for the early stages of exploration, when samples are not available as single crystals, but as crystalline powders. Samples are confined under pressure in an electric field and the increase in(More)
1 The effects of single doses of naproxen and sulphinpyrazone and of 4 and 8 days treatment with sulphinpyrazone on human platelet responsiveness were compared. 2 A single dose of sulphinpyrazone had no effect whereas a single dose of naproxen caused a five-fold depression in responsiveness to collagen. 3 Repeated administration of sulphinpyrazone led to a(More)
