This book documents the history of four ecclesiastical frescoes completed by artist Benjamin F. Long IV in Ashe County, North Carolina, in the 1970s and 1980s. The story of the Ashe County frescoes celebrates their setting in the Blue Ridge Mountains and testifies to Long's intensity, precision and stamina. Commissioned by the Ashe County Frescoes Foundation, the authors contextualize the artistic and the spiritual aspects of the frescoes by connecting the figures in the scenes with their sources in the Bible. Drawn from extensive interviews with the artist, this book explores the frescoes' uniqueness. Interviews with people used as models, assistants, volunteers and observers focus on the frescoes' impact on the community, and the role of the Ashe County Frescoes Foundation in the protection and preservation of these artworks.
It is difficult to imagine anything more important to the human population than safe drinking water. Lack of clean drinking water is still the major cause of illness and death in young children in developing countries. In more fortunate communities, where water treatment is practiced, the primary aim of water authorities is to provide water that is free from pathogens and toxins. Most countries now have water quality regulations, or guidelines, which are driving water authorities to produce purer water, with the minimum of contamination from natural or man-made origin. At the same time, consumers are demanding that chemicals added during the treatment of drinking water be kept to a minimum. As a consequence, conventional clarification methods are being challenged to comply with the new regulations and restrictions and our understanding of the mechanisms involved is being tested as never before. Interface Science in Drinking Water Treatment contains a rigorous review of water treatment practices from a fundamental viewpoint. The book includes material from leading experts in the field of water treatment, reviewing their specific fields of expertise against a background of colloid and surface chemistry, and examines each step of the journey from source to consumer tap. It therefore permits the reader to develop a deep understanding of the complex processes taking place and of the necessary treatments which are vital for the provision of safe and palatable drinking water. The book is aimed at researchers, educators and practitioners in science and engineering, particularly those involved in water treatment and colloidal chemistry. - Covers all existing water treatment processes, approached from a fundamental surface and colloid science viewpoint - Unique collection of R&D authors, all experts in water treatment processes - Comprehensive review of water treatment with a complete list of references
