Book Description
Plant production in hydroponics and soilless culture is rapidly expanding throughout the world, raising a great interest in the scientific community. For the first time in an authoritative reference book, authors cover both theoretical and practical aspects of hydroponics (growing plants without the use of soil). This reference book covers the state-of-the-art in this area, while offering a clear view of supplying plants with nutrients other than soil. Soilless Culture provides the reader with an understanding of the properties of the various soiless media and how these properties affect plant performance in relation to basic horticultural operations, such as irrigation and fertilization. This book is ideal for agronomists, horticulturalists, greenhouse and nursery managers, extension specialists, and people involved with the production of plants.* Comprehensive discussion of hydroponic systems, irrigation, and control measures allows readers to achieve optimal performance* State-of-the-art book on all theoretical aspects of hydroponics and soilless culture including a thorough description of the root system, its functions and limitation posed by restricted root volume* Critical and updated reviews of current analytical methods and how to translate their results to irrigation and fertilization practices * Definitive chapters on recycled, no-discharge systems including salinity and nutrition management and pathogen eradication * Up-to-date description of all important types of growing media

Book Description
The book is about bridging the huge gaps between what engineers know, what they do and why things go wrong. It puts engineering into a wider perspective so readers can see how it relates to other disciplines — especially science and technology. Many intellectuals have dismissed engineering as 'applied science', but this book shows how wrong it is to do so — engineers apply science, but their purpose is quite different.It takes the reader on a learning journey of reflections on the gaps between theory and practice in professional life — not just in engineering but across all disciplines. The learning is summarized through 20 learning points or lessons, each one placed in context. Some of the important lessons are about learning from failure, joining-up theory and practice, understanding process, classifying uncertainty, managing risks, finding resilience, thinking systems to improve performance and nurturing practical wisdom.

Book Description
This is the first book to bring together practical examples from around the world to show how geomorphological evidence can help in effective land utilisation and hazard risk assessment. Case studies provide important lessons in risk management, and experts provide summaries of current research. The text also promotes good practice and effective land use, and looks at problems caused by misuse of the environment and potential solutions based on geomorphological evidence.

Book Description
"Why bother with history? Keith Jenkins has an answer. He helps us re-think the "end of history", as signalled by postmodernity. Readers may disagree with him, but he never fails to provoke debate about the future of the past." Joanna Bourke, Professor of History, Birkbeck College Keith Jenkins’ work on historical theory is renowned; this collection presents the essential elements of his work over the last fifteen years. Here we see Jenkins address the difficult and complex question of defining the limits of history. The collection draws together the key pieces of his work in one handy volume, encompassing the ever controversial issue of postmodernism and history, questions on the end of history and radical history into the future. Exchanges with Perez Zagorin and Michael Coleman further illuminate the level of debate that has surrounded postmodernism, and which continues to do so. An extended introduction and abstracts which contextualize each piece, together with a foreword by Hayden White and an afterword by Alun Munslow, make this collection essential reading for all those interested in the theory and practice of history and its development over the last few decades.

Book Description
This book fills a gap in the growing academic discipline of food and agricultural tourism, offering the first multidisciplinary approach to food tourism and the role it plays in economic development, destination marketing, and gastronomic exploration. It provides a comprehensive introduction to the discipline by considering food tourism in connection with both cultural values and important issues in agriculture, food consumption and safety, and rural heritage and sustainability. The book is divided into four Parts. Part I defines the elements of food tourism and explains its relationship with sustainability. Part II provides an overview of rural development and demonstrates the impact of industrialization and globalization on eating habits. Part III focuses on food tourism studies and market segmentation techniques to help students understand customer needs regarding food tourism products. Finally, Part IV looks at the financial, policy, and legal requirements relating to food tourism development, providing hands-on tools for students entering food tourism businesses or industries. Complemented by a wide range of international case studies, key definitions, and study questions, Food and Agricultural Tourism is essential reading for students of tourism, geography, and economic development studies.

Book Description
Musicology, having been transmitted as a compilation of disparate events and disciplines, has long necessitated a 'magic bullet', a 'unified field theory' so to speak, that can interpret the steady metamorphosis of Western art music from late medieval modality to twentieth-century atonality within a single theoretical construct. Without that magic bullet, discussions of this kind are increasingly complicated and, to make matters worse, the validity of any transformational models and ideas of the natural evolution of styles is questioned and even frowned upon today as epitomizing a grotesque teleological bigotry. Going against current thinking, Henry Burnett and Roy Nitzberg claim that the teleological approach to observing stylistic change is still valid when considered from the purely compositional perspective. The authors challenge the traditional understanding of development, and advance a new theory of eleven-pitch tonality as it relates to the corpus of Western composition. The book plots the evolution of tonality and its bearing on style and the compositional process itself. The theory is not based on the diatonic aspect of the various tonal systems exploited by composers; rather, the theory is chromatically based - the chromatically inflected octave being the source not only of a highly ingenious developmental dialectic, but also encompassing the moment-to-moment progression of the musical narrative itself. Even the most profound teachings of Schenker, and the often startlingly original and worthwhile speculations of Riemann, Tovey, Dahlhaus and others, still provide no theory of development and so are ultimately unable to unite the various tendrils of the compositional organism into a unified whole. Burnett and Nitzberg move beyond existing theory and analysis to base their theory from the standpoint of chromatic 'pitch fields'. These fields are the specific chromatic pitch choices that a composer uses to inform and design a complete composition, utilizing

Book Description
This lively and readable survey introduces students to key areas of the field and shows how to apply an anthropological approach to the study of contemporary world religions. Written by an experienced teacher, it covers all of the traditional topics of anthropology of religion, including definitions and theories, beliefs, symbols and language, and ritual and myth, and combines analytic and conceptual discussion with up-to-date ethnography and theory. Eller includes copious examples from religions around the world – both familiar and unfamiliar – and two mini-case studies in each chapter. He also explores classic and contemporary anthropological contributions to important but often overlooked issues such as violence and fundamentalism, morality, secularization, religion in America, and new religious movements. Introducing Anthropology of Religion demonstrates that anthropology is both relevant and essential for understanding the world we inhabit today.
