Introduction to Magnetic Materials, 2nd Edition covers the basics of magnetic quantities, magnetic devices, and materials used in practice. While retaining much of the original, this revision now covers SQUID and alternating gradient magnetometers, magnetic force microscope, Kerr effect, amorphous alloys, rare-earth magnets, SI Units alongside cgs units, and other up-to-date topics. In addition, the authors have added an entirely new chapter on information materials. The text presents materials at the practical rather than theoretical level, allowing for a physical, quantitative, measurement-based understanding of magnetism among readers, be they professional engineers or graduate-level students.
This must-have text provides an insight into the science behind radiographic technology. Suitable for radiography and radiology students at all levels, the text uses illustrations and simple analogies to explain the fundamentals, while retaining more complex concepts for those with a more advanced knowledge of radiological physics. Updated by authors Martin Vosper, Andrew England and Victoria Major to reflect advances and key topics in medical imaging practice, this text will support radiographers in their core role of obtaining high quality images and optimal treatment outcomes. Strong links between theory and practice throughout, with updated clinical scenarios Clear and concise text featu...

Representation and party politics is one of the core themes of the comparatvie study of politics. What function do parties serve? What is the essential relationship between people and parties? Are parties simply a way of reproducing a political elite that rules and governs? These are some of the questions Graham asks in his analysis of our understandings of political parties, their internal structures and external realtions. While surveying a rich literature on parties and party systems, emphasizing the continuing relevance of earlier writings, the author sets out the main problems that should be addressed in the study of political parties. We are then lucidly led through a range of empirical cases illustrating party performance in relation to electoral behaviour, and introduced to a range of theoretically-driven models of performance, behaviour and recruitment. The book culminates in a superb discussion of factionalism within parties, and an epxloration of populism in mass politics. Graham′s challenging work introduces and reveals aspects of party dynamics and representation which are essential to students of politics and political scientists alike.
