Saponins are glycosides of triterpenes, steroids or steroidal alkaloids. They can be found in plants and marine organisms. Very diverse biological activities are ascribed to saponins and they play important roles in food, animal feedstuffs, and pharmaceutical properties. This volume provides a selection of recent work on saponins presented at a symposium in Pulawy, Poland, in 1999. Many different aspects are treated: analysis, separation, biological activities, relevant use in human and animal nutrition, and ecological significance. This book will be of use to researchers both in universities and industry.

Building on a trans-disciplinary, feminist project that foregrounds the bodies of those at the 'sharp end' of various forms of international activity, such as immigration, development and warfare, the chapters included in this book cover a variety of sites, concerns, and hopes. These range from the fraught geopolitics of marriage and birth in Ladakh, India, to the fate of detained migrant children in the U.S., and from the human rights abuses of women and children in Uzbekistan to the body politics of aid workers in Afghanistan. The collective aim is to expose the force relations that operate through and upon those bodies, such that particular subjectivities are enhanced, constrained, and put to work, and particular corporealities are violated, exploited, and often abandoned. Oriented around issues of security, population, territory, and nationalism, these chapters expose the proliferating bodies of geopolitics, not simply as the bearers of socially demarcated borders and boundaries, but as vulnerable corporealities, seeking to negotiate and transform the geopolitics they both animate and inhabit. This book was originally published as a special issue of Gender, Place and Culture: A Journal of Feminist Geography.

"The experience of each one of us is the treasure of all. " Gerard de Nerval In 1952, J. L. Lortat-Jacob [2] reported the first programmed right hepatectomy, which had been carried out for a hepatic metastasis of colorectal origin. Today, excisional surgery of the liver has become a routine procedure, with a low mortality and morbi dity. The varieties of excision have increased and been modified in accordance with the site and number of lesions to be treated. These advances notably stem from both the work on the segmental anatomy of the liver by Couinaud [1] and that of Ton That Tung [3], which have opened the way to a simplified and segmental method of hepa tic resection that is both safe and reliable. This progress has been greatly facilitated by a better knowledge of the effects of vascular clamping of the liver, and by the intro duction of new techniques including per-operative ultrasound, the ultrasonic dissector and the argon coagulator. Improvements in anresthesia have also contributed to the safety of these procedures. The high incidence of colorectal cancer (the second commonest cause of cancer death in France) and the frequent occurrence of hepatic metastases from this tumour, more than justify the search for an effective therapeutic management pro tocol. The important place of surgical resection, the technical advances outlined above, and the prospect of new treatment modalities using adjuvant therapy, are additional reasons for preparing a report on this subject.

This is the first comprehensive monograph to look in depth at saponins. Saponins are glycosides of triterpenes, steroids or steroid alkaloids which have a very wide distribution in plants and some marine organisms. Their biological activity includes haemolysis and fish poisoning, and the steroid saponins are essential for the manufacture of oral contraceptives and sex hormones. Saponins have also been exploited commercially as soap substitutes and in several other industrial applications. This book gives detailed information on the occurrence and distribution of saponins, their structural types, isolation, analysis and structure determination. Biological and pharmacological activities are discussed, as are aspects of commercial and industrial use. The volume provides a valuable source of data for the different classes of compound and includes and extensive list of references.

This volume brings together exciting new research by anthropologists working on mainland Southeast Asia, in honor of anthropologist Charles F. Keyes. It addresses concepts central to Keyes's own work--ethnicity, religion, and modernity--as they can be applied to the countries of Thailand, Vietnam, Cambodia, and Laos.

In addition to three sections covering different aspects of anthropological research, the book also contains a biography of and interview with Keyes and a selected bibliography of his work.

John A. Marston is a professor and researcher at the Center for Asian and African Studies of El Colegio de Mexico in Mexico City.

The objectives of this project were to: 1) evaluate the present geomorphic condition of the Washita River through the Battlefield; 2) evaluate the adjustment of the present channel to the prevailing water and sediment supply to the channel, and how this adjustment has changed through time; 3) evaluate the likelihood that a modified channel similar to that which existed in 1868 could remain in equilibrium with the present conditions of flow and sediment; and 4) based on the findings of this study, develop conceptual alternatives for achieving a stable channel form and functional riparian system along distinct reaches of the river that are as close to the historic conditions as possible.

A teenage rebel becomes struck down with Epilepsy and his life changes for ever but Glyn Marston battles on and one day decides to take up long distance running to prove his fitness to himself. This takes him on an amazing journey that will see him run in the most gruelling races around the World, run across the Grand Canyon, run in races of 155 miles non stop running and breaking numerous World Records for treadmill running, and receiving a personal audience with HRH The Queen. Named as Walsall's running and sporting Ambassador Glyn Marston receives numerous awards for his charity fundraising and his extreme athletism. With numerous TV, Film and Sporting personalities as his close friends, Glyn became a Nationally respected Athlete and also became a top ranked runner in the Ultra distance running scene.However a serious knee injury was to force Glyn to retire from running and at the same time he was to face a huge challenge to save his marriage.... A True story of a local and National Hero who became a true inspiration through his endeavours, a great read.

"Ein hAchst verworrenes Quartier, ein StraAennetz, das jahrelang von mir gemieden wurde, ward mit einem Schlage A1/4bersichtlich, als eines Tages ein geliebter Mensch dort einzog. Es war, als sei in seinem Fenster ein Scheinwerfer aufgestellt und zerlege die Gegend mit LichtbA1/4scheln." Walter Benjamin Schriften (Bd. 1.). Frankfurt a. M. (Suhrkamp Verlag) 1955. Die meisten Menschen haben ein bestimmtes VerstAndnis ihres eigenen Lebens und verfA1/4gen A1/4ber mancherlei Kenntnisse der Umgebung - des Viertels, der Stadt, des Landes -, in der sie leben. Doch obwohl die Verflechtungen zwischen den LAndern und Regionen der Erde immer enger und vielfAltiger werden, weiA die Mehrzahl von uns letztlich auAerordentlich wenig A1/4ber das Leben anderer Menschen in anderen Gesellschaften oder auch darA1/4ber, wie deren Leben mit dem unsrigen zusammenhAngt. Das Zitat von Walter Benjamin mag verdeutlichen, dass wir Orte und Regionen erst verstehen kAnnen, wenn sie Bedeutung fA1/4r uns erlangen. Dieses Buch ist eine EinfA1/4hrung in die Humangeographie, die genau dieses Ziel verfolgt. Humangeographie zu studieren, bedeutet, vereinfacht gesprochen, sich mit den dynamischen und komplexen Beziehungen zwischen Menschen und den von ihnen bewohnten RAumen zu beschAftigen. Das vorliegende Buch vermittelt Studierenden die grundlegenden geographischen Techniken und Konzepte, die sie benAtigen, um die KomplexitAt von Orten und Regionen zu erfassen und die Wechselbeziehungen zwischen ihrem eigenen und dem Leben von Menschen in anderen Teilen der Erde richtig einschAtzen zu kAnnen. Das Buch stellt einen neuen humangeographischen Ansatz dar, der den bedeutenden VerAnderungen Rechnung trAgt, die RAume globaler, regionaler und lokaler Dimension in jA1/4ngster Zeit erfahren haben. Diese VerAnderungen umfassen eine Vielzahl von Prozessen und PhAnomen wie die Globalisierung der Industrie oder der Zusammenbruch des sowjetischen Reiches. Der in Humangeographie verfolgte Ansatz fA1/4hrt nicht nur zu einem VerstAndnis neuer Vorstellungen, Konzepte und Theorien hinsichtlich der genannten VerAnderungen, sondern erschlieAt darA1/4ber hinaus die Grundlagen der Humangeographie: die Prinzipien, Konzepte, das theoretische GerA1/4st und das Basiswissen, das fA1/4r weiterfA1/4hrende, speziellere Studien benAtigt wird. Das Buch hat sich A1/4beraus erfolgreich als Lehrbuch der Humangeographie eingefA1/4hrt. Es ist in der Neuauflage komplett aktualisiert, so wurde ein Kapitel A1/4ber Sozialgeographie ergAnzt, und es enthAlt viele neue Grafiken sowie eine Vielzahl an anschaulichen neuen Fotos.
