Many industrial, power generation and chemical processes produce unwanted fine particulate material as a consequence of their operation. Electrostatic precipitation is a highly efficient method of removing entrained particulate contaminants from exhaust gases and is extensively used in these industries to limit particulate emissions. New legislation aimed at improving the environment by further limiting these discharges has resulted in the technique undergoing considerable development over the past decade, to the point where it has become the method of choice, over a wide range of applications, for limiting particulate discharges. In this new book, the editor has brought together an international team of contributors, mainly industrialists and consultants, to produce an authorative and practical guide to electrostatic precipitation. This book is of interest to all those in process industries or power generation and to academics concerned with gas cleaning and environmental issues.
It is well known that children's activities are full of pretending and imagination, but it is less appreciated that animals can also show similar activities. Originally published in 2002, this book focuses on comparing and contrasting children's and animals' pretenses and imaginative activities. In the text, overviews of research present conflicting interpretations of children's understanding of the psychology of pretense, and describe sociocultural factors which influence children's pretenses. Studies of nonhuman primates provide examples of their pretenses and other simulative activities, explore their representational and imaginative capacities and compare their skills with children. Although the psychological requirements for pretending are controversial, evidence presented in this volume suggests that great apes and even monkeys may share capacities for imagination with children, and that children's early pretenses may be less psychological than they appear.

Particle Technology and Applications presents the theoretical and technological background of particle science and explores up-to-date applications of particle technologies in the chemical, petrochemical, energy, mechanical, and materials industries. It looks at the importance of particle science and technology in the development of efficient chemi
Scientists directly involved in studying the Exxon Valdez spill provide a comprehensive synthesis of scientific information on long-term spill effects.
Detecting Ecological Impacts: Concepts and Applications in Coastal Habitats focuses on crucial aspects of detecting local and regional impacts that result from human activities. Detection and characterization of ecological impacts require scientific approaches that can reliably separate the effects of a specific anthropogenic activity from those of other processes. This fundamental goal is both technically and operationally challenging. Detecting Ecological Impacts is devoted to the conceptual and technical underpinnings that allow for reliable estimates of ecological effects caused by human activities. An international team of scientists focuses on the development and application of scientific tools appropriate for estimating the magnitude and spatial extent of ecological impacts. The contributors also evaluate our current ability to forecast impacts. Some of the scientific, legal, and administrative constraints that impede these critical tasks also are highlighted. Coastal marine habitats are emphasized, but the lessons and insights have general application to all ecological systems.
