The Hydrocyclone reviews data on the theoretical, design, and performance aspects of the liquid cyclone, hydraulic cyclone, or hydrocyclone. The book aims to be a source of reference to those who are in industries employing the use and application of the hydrocyclone. The text covers the historical development of the cyclone; flow pattern and distribution of velocities within the cyclone body; operational characteristics and areas of application in different phase separations; and the operating and design variables affecting the performance of the hydrocyclone. Categories of cyclone; commercially available cyclone equipment; and the specific industrial applications of the hydrocyclone are also surveyed. The text will be of practical use to industrial engineers, mechanical engineers, plant operators, miners, and researchers.
This book is about understanding the value of environmental services in South Asia. It provides an overview of different environmental problems in South Asia and examines how economic valuation techniques can be used to assess these problems. It brings together multiple case studies on valuation undertaken by economists and environmental scientists from Bangladesh, India, Pakistan, Nepal and Sri Lanka under the aegis of the South Asian Network for Development and Environmental Economics (SANDEE). The book addresses the challenges of valuing environmental changes that are unique to developing countries. Each chapter starts with a description of an environmental problem and the valuation strategy used, followed by a discussion of estimation methods and results. It is designed to serve as a reference book for students, teachers, researchers, non-government organizations and practitioners of environmental valuation. Those interested in development and environmental economics, and natural resource management policies, will also find it useful.
The expanded fifth edition of Environmental Hazards provides a balanced overview of all the major rapid-onset events that threaten people and what they value in the twenty-first century. It integrates cutting-edge material from the physical and social sciences to demonstrate how natural and human systems interact to place communities of all sizes, and at all stages of economic development, at risk. It also shows how the existing losses to life and property can be reduced. Part I of this established textbook defines basic concepts of hazard, risk, vulnerability and disaster. Critical attention is given to the evolution of theory, to the scale of disaster impact and to the various strategies that have been developed to minimise the impact of damaging events. Part II employs a consistent chapter structure to explain how individual hazards, such as earthquakes, severe storms, floods and droughts, plus biophysical and technological processes, create distinctive patterns of loss throughout the world. The ways in which different societies make a positive response to these threats are placed in the context of ongoing global change. In this extensively revised edition: An entirely new and innovative chapter explains how modern-day complexity contributes to the generation of hazard and risk Additional material supplies fresh perspectives on landslides, biophysical hazards and the increasingly important role of global-scale processes The increased use of boxed sections allows a greater focus on significant generic issues and offers more opportunity to examine a carefully selected range of up-to-date case studies Each chapter now concludes with an annotated list of key resources, including further reading and relevant websites. Environmental Hazards is a well-written and generously illustrated introduction to all the natural, social and technological events that combine to cause death and destruction across the globe. It draws on the latest research findings to guide the student from common problems, theories and policies to explore practical, real-world situations. This authoritative, yet accessible, book captures both the complexity and dynamism of environmental hazards and has become essential reading for students of every kind seeking to understand the nature and consequences of a most important contemporary issue.
