Recent advances in the theory of the conduction mechanism in semiconductors and semiconductor-metal systems are reviewed, together with their properties and applications. Since the more important advances relate to systems whose properties depend upo

The problem of end-breakage in ring spinning is discussed in terms of simple mathematical model. Absolute values of end-breakage rate cannot calculated, but the treatment enables the relative importance of such factors tension, regularity of yarn, an

The Institute's Graduateship Examination, as a new external examination free from the difficulties of co-ordination between different centres, offers an excellent opportunity to depart from the conventional type of examination question in favour of q

The word ‘crystal’ comes from a Greek word meaning clear ice which was also applied to rock crystal (clear, transparent quartz). It was not until about the 17th century that the word was extended to other naturally occurring, transparent minerals

The effects of air drag on the shape of the balloon formed in ring spinning are discussed and it is shown that air drag : allows fine yarns to be spun without balloon collapse at a greater spindle speed or with a smaller specific tension (tension ÷

Some possible reasons for the declining stature of the traditional textile industry in the modern industrial scene are examined in detail. It is concluded that the principal reason is the fact that the industry has not sufficiently used recently intr
