The pH electrode offers by far the greatest sensitivity and rangeability of any industrial process measurement. To realize the full potential of this opportunity requires extrao rd inary performance of mixing equipment, contro l valves, reagent delivery systems, flow meters, control system design, and controller tuning. This book is designed to cover all of the bases but not get the user lost in the details. Since each of these topics could be a book in itself, the emphasis here is on cutting straight to the chase of concepts critical for a successful pH system. Key insights and rules of thumb a rc inserted to congeal principles and practices that address the essential requirements of pH applications. The book should appeal to both the generalist and the specialist. This book is designed to bring togethe r the chemist, control engineer, instrument technician, process engineer, and project manager to literally and figuratively put them on the same page.

With its immense capacity for adsorption from gas and liquid phases, activated carbon is a unique material. It occupies a special place in terms of producing a clean environment involving water purification as well as separations and purification in the chemical and associated industries. In these roles, it exhibits a remarkable efficiency as the international production is a littie more than half a million tonnes per year, with perhaps 2 million tonnes being in continuous use. This is equivalent to the allocation of 200 mg per person of the world population to be compared with the world use of fossil fuels of 2 tonnes per person of the world population. Much is already written about activated carbon such that the Google search engine will offer over one million pages from the Internet. These pages are mosdy descriptive and uncoordinated. Currendy, there exists a need for a text which establishes a framework into which factual information can be located and explained. Further, carbon science has expanded rapidly in recent years with considerable relevance to an understanding of activated carbon. Again, these information are mostly uncoordinated and need to be assimilated into a comprehensive story. This assimilation is the purpose of this book.

Roughly a century has passed after the first ideas by Oliver Lodge, George Francis FitzGerald and Kristian Birkeland about particle clouds emanating from the Sun and interacting with the Earth environment. Only a few decades after the formulation of the concepts of a continuous solar corpuscular radiation by Ludwig Biermann and a solar wind by Eugene Parker, heliospheric physics has evolved into an important branch of astrophysical research. Numerous spacecraft missions have increased the knowledge about the heliosphere tremendously. Now, at the beginning of a new millennium it seems possible, by newly developed propulsion technologies to send a spacecraft beyond the boundaries of the heliosphere. Such an Interstellar Probe will start the in-situ exploration of interstellar space and, thus, can be considered as the first true astrophysical spacecraft. The year 2000 appeared to be a highly welcome occasion to review the achievements since the last COSPAR Colloquia 11 years ago, to summarize the present developments and to give new impulses for future activities in heliospheric research.

The political history of the modern State of Israel can be divided into two distinct periods: 1948 to 1967 and post-1967. These periods are distinguished both by the nature and interplay of the problems that the state faced, and by the characteristic functioning of the latter's democratic political structures in coping with those problems. This book deals with the first period, which I have termed the founding period. At one level, it seeks to provide an interpretative political history of that period as a whole: by focusing on the establishment and operation of new political structures; problems of statehood and social integration; relations among political parties; the aspirations and actions of political leaders; and the role of the electorate. These topics, portrayed in their contemporary context, are set against the background of the social, economic, and political structures inherited from the pre-state era.
