Carbon fibre reinforced carbon composites form a very specialized group of materials. They may be considered as a development of the family of carbon fibre reinforced polymer composites which are becoming ever more prevalent in modern engineering. Since the early 1960s a large number of so-called'advanced materials'have appeared on the scene. Carbon~arbon is arguably the most successful of all these products finding many and varied applications. In the field of Formula 1 motor racing for example, the present levels of performance simply could not be achieved without the use of carbon-carbon brakes and clutches. Despite the materials'obvious assets, they have not, and will not, reach their full potential until their inherent problems of excessive production costs and oxidation resistance have been addressed properly. In this respect the'carbon-carbon story', of much potential but only limited success, serves as a lesson to all those involved in materials research, development and application. In writing this book I have tried to set up a logical progression of what the materials are, how they are made, what their assets and deficiencies are, what they are used for and to what extent they are commercially exploited. Each specialized chapter may be considered in isolation or as part of a sequence, whereas the final chapter provides a summary of the principal concepts as well as a basic review of the economic situation past, present and, hopefully, future.

In his illuminating, well-researched book examining the site of Et-Tell, also known as Bethsaida, Carl E. Savage explores archaeological evidence to offer readers a portrait of the religious beliefs and practices of the community living near the north shore of the Sea of Galilee during the first century CE. In the study of the cultural and social matrix of the first century in the Galilee, scholars have commonly prioritized written sources over archaeological evidence because written sources seem to contribute more directly to an understanding of the religious beliefs and practices of a community. However, there exist many competing views of the landscape during that time due to the varying interpretations of the textual sources. Using archaeological data from Bethsaida itself, Savage investigates the material practices of Bethsaida's ancient inhabitants, describing these practices as significant indicators of their sense of place both ideologically and geographically. He evaluates the historical plausibility of various social reconstructions for the region, and finds that the image that emerges of first-century Bethsaida is one similar to those of other Jewish communities in the Galilee.
