Water has become one of the most important issues of our time intertwined with global warming and population expansion. The management of water supplies and the conservation of water resources remains one of the most challenging yet exciting issues of our time. Water and wastewater treatment technologies are constantly evolving creating an increasingly sustainable industry that is one of the world's largest and most interdisciplinary sectors, employing chemists, microbiologists, botanists, zoologists as well as engineers, computer specialists and a range of different management professionals.This accessible student textbook introduces the reader to the key concepts of water science and technology by explaining the fundamentals of hydrobiology, aquatic ecosystems, water treatment and supply, wastewater treatment and integrated catchment management. This fourth edition is extensively changed throughout, with new coverage of the effects of climate change, environmental assessment, sustainability and the threat to biodiversity.The text serves as a primer for both undergraduate and graduate students in either science or engineering who have an interested in freshwater biology/hydrobiology or environmental engineering. It is also useful as a unified transitional course for those who want to span the traditional areas of engineering, biology, chemistry, microbiology or business. Professionals and consultants will also find the book a useful reference.

This book is an examination of the music of the Balinese gendér wayang, the quartet of metallophones - gendér - that accompanies the Balinese shadow puppet play - wayang kulit. The book focuses on processes of musical variation, the main means of creating new music in this genre, and the implications of these processes for the social and historical study of Balinese music, musical aesthetics, concepts of creativity and compositional methods. Dr Nick Gray tackles a number of core ethnomusicological concerns in a new way, including the relationship between composition and improvisation, and also highlights issues specific to Balinese music, including the importance of flexibility in performance, an aspect that has been largely ignored by scholars. Gray thus breaks new ground both in the study of issues relating to improvisation and composition and in Balinese music studies.

David Hillyard, founder of the famous firm of boatbuilders in Littlehampton, was born in the late nineteenth century, at the height of the Big Boat era. His family were stalwarts of ­Rowhedge in Essex, where the aristocratic owners of the enormous cutters dicing in the Solent sent their skippers to pick their racing crews of hard-bitten fishermen. Yachts, in those days, were for the very rich, but the men who sailed them were often the reverse. Perhaps it was a consciousness of this divide that led ­Hillyard—a devout Christian, descended from a long line of fishermen—to build boats that were robust, practical, and within the means of those lacking the advantage of dukedoms or armaments factories.This account of David Hillyard’s voyage from apprentice boatbuilder to founder of a boatbuilding dynasty will be deeply interesting not only to owners of his boats and enthusiasts of traditional boatbuilding, but to anyone interested in the story of messing about in boats as practised in Britain. It also provides fascinating insights into the development of a small but significant corner of the relationship between the people of these islands and the seas that surround us.
