Definition of the barrier The interstitial fluid (rSF) of the brain is separated from the blood by the blood-brain barrier (BBB). This barrier must not be thought of as a single entity or as an absolute restriction to all molecules, but as a multiple structure located at several sites within the brain. The first of these interfaces is located at the endothelium of the brain capillaries. Secondly there is a potential site for interchange on the outer linings of the brain between the dura and the arachnoid membranes. Thirdly, there are the choroid plexuses and the cerebrospinal fluid (CSF) which is in contact with the very permeable internal ependymal lining of the brain (Figure 1. 1). Finally there are areas of the brain which lack a blood-brain barrier. These areas constitute the circumventricu lar organs and have leaky capillaries with a barrier at the ependyma which limits the spread of molecules from those regions (Figure 1. 2). Each of these BBB sites has its own characteristic permeability and transport functions. We will now consider the properties of each of these barrier sites between the blood and the brain. THE CEREBRAL CAPILLARY ENDOTHELIUM Morphology This interface has both the largest surface area and the shortest path length between the blood and the brain rSF. The cerebral capillaries, which at first sight seem little different from the rest of the systemic circulation, are in fact unique to the brain."
The scientific contribution of Mike Bradbury to the study of the blood-brain barrier is considerable and wide-ranging, starting with his M.D. thesis in 1962 and still continuing today. The varied spectrum of topics relating to the blood-brain barrier presented in this volume and the many geographical locations from which both speakers and participants gathered to attend the symposium are a fitting testament both to Mike's wide-spread influence in the field and to the esteem in which he is held. When we first had the idea of afestschrift to mark Mike's retirement as Professor of Physiology at King's College London and the beginning of a new vie libre as scientist and yachtsman the plan was initially for a gathering of all of the many colleagues, collaborators and students who had worked with him over the years. However what we had not taken into account was the closeness of the international community of workers in the field, the widespread influence that Mike had wielded and the speed with which word would spread. We should have anticipated all three. The final outcome was an excellent symposium with the majority of the world's key workers either contributing or attending. We hope that this volume presents an adequate record of the meeting.
This book analyses the development of German territorial states in the nineteenth century through the prism of five Mittelstaaten: Bavaria, Saxony, Hanover, Wurttemberg, and Baden. It asks how a state becomes a place, and argues that it involves a contested and multi-faceted process, one of slow and uneven progress. The study approaches this question from a new and crucial angle, that of spatiality and public mobility. The issues covered range from the geography of state apparatus, the aesthetics of German cartography and the trajectories of public movement. Challenging the belief that territorial delimitation is primarily a matter of policy and diplomacy, this book reveals that political territories are constructed through daily practices and imagination.
Agency, Illusion, and Well-Being is a collection of essays drawn from Jerome Segal's earlier books, including essays from Agency and Alienation, Joseph's Bones, Graceful Simplicity, and Creating the Palestinian State Arranged thematically into a coherent new whole, this selection of essays presents Jerome Segal's contribution to philosophy and moral psychology in a definitive edition.

The Olive Branch from Palestine provides a new narrative of the Palestinian effort to end the Israeli-Palestinian conflict and offers a bold plan for ending this conflict today, a proposal that focuses on Palestinian agency and the power of the Palestinians to bring about the two-state solution, even in the absence of a fully committed Israeli partner. In part 1, Jerome Segal provides an analytical and historical study of the 1988 Palestinian Declaration of Independence, a remarkable act of unilateral peacemaking through which the PLO accepted the legitimacy of the 1947 Partition Resolution and thereby redefined Palestinian nationalism. In part 2, he proposes a new strategy in which, outside of negotiations, the Palestinians would advance, in full detail, the end-of-claims/end-of-conflict peace plan they are prepared to sign, one that powerfully addresses the Palestinian refugee question and is supported by the refugees themselves yet does not undermine Israel as a Jewish-majority state.
Groups, teams, and other new ways of working together have become commonplace in today's organizations. In spite of all of these changes, one element remains the same: the basic building block of all work activities is the individual employee. Points of Influence helps coach managers, team leaders, and trainers to gain a better understanding of employee motivation and how they can influence behavior, increase their own personal self-awareness, and expand their managerial skills.

Recent extensive activity on severe plastic deformation (SPD) as a new materials processing technology has generated vast experimental and analytical amounts of information. However, there is still a strong need for a multidisciplinary understanding of SPD. This book consists of in-depth analyses of the fundamentals and engineering of SPD on processing mechanics, the micro-mechanics of plastic deformation and the physics of the structure-properties relationship. This book bridges the gap between existing approaches, resolves certain controversies, and provides a united description of SPD at different scales.
""Graceful Simplicity "is a marvelously textured analysis of the elusive ideal of simple living. For those eager to find a way to get off the 'more is better' treadmill, Jerome Segal offers insight and hope. . . . A must read."--David Shi, author of "The Simple Life " "Segal articulates a message that is both revolutionary and just plain sensible--consume less and take time to enjoy life more. He rescues us from a consumerism gone haywire without advocating isolationism. In a new and better way we are still our brother's keeper."--Arlie Russell Hochschild, author of "The Time Bind: When Work Becomes Home and Home Becomes Work " "Segal wants a political movement to create a functioning public sector, complete with universal health insurance and a sturdy safety net. Numerous and powerful interest groups will fight such reforms with bitter determination. But what could provide a better source of drama and adventure than the struggle to make the simpler life a viable option for all?"--Barbara Ehrenreich, "Civilization"
