Today, membranes and membrane processes are used as efficient tools for the separation of liquid mixtures or gases in the chemical and biomedical industry, in water desalination and wastewater purification.

Despite the fact that various membrane processes, like reverse osmosis, are described in great detail in a number of books, processes involving ion-exchange membranes are only described in a fragmented way in scientific journals and patents; even though large industrial applications, like electrodialysis, have been around for over half a century. Therefore, this book is emphasizing on the most relevant aspects of ion-exchange membranes.

This book provides a comprehensive overview of ion-exchange membrane separation processes covering the fundamentals as well as recent developments of the different products and processes and their applications. The audience for this book is heterogeneous, as it includes plant managers and process engineers as well as research scientists and graduate students.

The separate chapters are based on different topics. The first chapter describes the relevant Electromembrane processes in a general overview. The second chapter explains thermodynamic and physicochemical fundamentals. The third chapter gives information about ion-exchange membrane preparation techniques, while the fourth and fifth chapter discusses the processes as unit operations giving examples for the design of specific plants.

1. First work on the principles and applications of electrodialysis and related separation processes.
2. Presently no other comprehensive work that can serve as both reference work and text book is available
3. Book is suited for teaching students and as source for detailed information.

So you want to be a rock 'n' roll star? In a future that isn't distant enough, you'll have to sell your soul to MTV just to pick up a guitar. And then they start carving you up, making you over in the mega-media image of glitter and bone.

Poor Ben Tendo, he just wanted to play music and make love to Jessika . . _Tonguing the Zeitgeist_, finalist for the 1995 Philip K. Dick Award for best science fiction novel, is a social satire in the tradition of Anthony Burgess's _A Clockwork Orange_ about the music industry and the commercialization of the arts..

The formation of ore deposits and the patterns of mineral alteration in rocks frequently involves the transport of large amounts of dissolved solids, sometimes transiently, but often over long periods of time. Knowing or suspecting this, we logically seek to resolve several questions: What are the large- and small-scale patterns of flow in geological materials? What is the direction and rate of flow in a given structure? What factors control the rates of chemical reaction within the rocks? What governs the dissolution of materials in some regions and their deposition in other areas that, over eons, leads to the distribution of minerals we see today? The search for answers to these issues involves a combination of approaches and subjects that includes geochemistry, structural geology, and fluid mechanics. In Flow and Reactions in Permeable Rocks, Dr. Owen Phillips provides the first book-length work that connects these different fields of study and applies them to the problem of flow and flow-controlled reaction in rocks. The author begins by specifying the general physical and chemical principles that govern fluid flow and chemical reactions in rocks. He then develops the theoretical underpinnings for a variety of different patterns of flow and for the three basic types of flow-controlled reaction: fronts, gradient reactions, and reactions in mixing zones. In the next chapter he explores some conditions for stability and instability in fluid flow, for instance the conditions under which one state of flow pattern spontaneously evolves into another. Finally, Dr. Phillips describes in detail the two great driving forces of large-scale fluid circulation in rocks: pressure differences and thermal convection. Typical geological examples are given and, wherever possible, compared to numerical results or field observations. The analytical developments require some familiarity with college-level mathematics, but derivations are easy to follow or may even be skipped by the trusting reader..

Various separation membranes have been developed since their discovery over half a century ago, providing numerous benefits and fulfilling many applications in our everyday lives. They lend themselves to techniques ranging from microfiltration and gas separation, to what can be considered as the most advanced technique - ion exchange.

Over the last century and a half, groundwaters have become contaminated by a growing number of organic and inorganic substances ranging from petroleum-derived hydrocarbons to radioactive compounds, to cancer-causing hexavalent chromium. The importance of uncontaminated groundwater for agriculture, human consumption, and the environmental health of ecosystems is paramount to the health and productivity of industrial society. Water scientists and managers are focused on developing cost-effective methods to reverse this trend.

Several methodologies have been developed, however few are as cost-effective as the use of readily available materials, such as iron and organic compost, for absorbing and isolating contaminants within the matrix of a permeable barrier. The Handbook of Groundwater Remediation using Permeable Reactive Barriers presents readers with this latest technology and developments within four main sections:

1. Innovations in Design, Construction, and Evaluation of PRBs
2. Development of Reactive Materials
3. Evaluations of Chemical and Biological Processes
4. Case Studies of Permeable Reactive Barrier Installations

The Handbook is one of the first references specifically on this topic. It is an excellent fit for graduate students entering this emerging field as well as professionals conducting research or implementing this technology..

Interest in prescribing rigid gas permeable (RGP) contact lenses is on the rise, fueled by the increased use of orthkeratology, bifocal lenses, and advances in corneal topography (making fitting easier). This concise and comprehensive resource provides valuable coverage for the prescribing and fitting of RGP lenses. Based on the authors' years of expertise in fitting these lenses, this clinically oriented manual also includes a companion CD-ROM to illustrate the fitting techniques.

• Content focuses specifically on rigid gas permeable contact lenses so all the essential information needed for prescribing and fitting is in one, convenient resource.
• A companion CD-ROM illustrates the difficult fitting techniques encountered with RGPs.
