First published in 1988, this work provides a comprehensive picture of the range of physical environments in Africa, focusing upon those characteristics and issues central to the management of environmental resources. Beginning with an overview of the geographical and environmental history of Africa, the authors also provide to the evolution of the management of resources and then details a broadly defined ecosystem approach, in which major environmental resource issues are identified and addressed in the tropical rainforest, the Savannah dry-forest, the arid and semi-arid areas, the highlands, and the extra-tropical zones of Northern and Southern Africa. The book is designed to contribute to a better understanding of African environmental and resource-management problems and this reissue should be welcomed by students of Africa and of environmental resource management problems in general.

Increasingly, pathologists are being confronted with the effects of a number of complex devices on the body. Cardiac pace-makers are becoming increasingly sophisticated, ventricular support systems for the heart are well established, and vascular and other protheses are being used in increasing numbers. New joint systems, contraceptive devices used as drug delivery systems, and the use of new cement materials all provide challenges in terms of their pathology. The articles in this text collectively form a body of information on these devices not available elsewhere and with an up-to-date bibliography.

Increasing specialisation in pathology reflects the progressive changes in medical practise. The advent of a specialist with a new interest in a hospital or clinic may present the pathologist with a need to extend his or her knowledge to be able to work closely with the clinical practi tioner in order to provide adequate clinical care. Some sub-specialisations are long established, such a one is neu ropathology. However, an exclusive specialist practise is generally con fined to neurosurgical centres and much neuropathology is of necessity, executed by geneni.l pathologists. The areas covered by this volume are those which are commonly managed by the generalist. Professor Adams' account of how the skull and brain should be examined here will give confidence to many by defining a good technique and the careful description of various kinds of vascular injury lesions resulting from raised intracranial pressure will help to clarify repeated difficulty. More subtle forms of damage are also considered in detail. Professor Weller provides a detailed account of how the central nervous system may be examined in a way which permits all of us to prepare material which will allow adequate investigation of central nervous system disease and the proper examination of peripheral nerves. This chapter will become a "handbook" and will be of interest to those in training and established practitioners. Muscle biopsy is also dealt with; this is an area of investigative concern for many gener alists. The role of that singular neuropathological technique is very clearly emphasized.

La pathologie vasculaire a ete tres marquee par les progres biologiques de ces vingt demieres annees. Le systeme arteriel est main tenant considere comme un organe a part entiere. Modelee au cours de l'organogenese par les facteurs hemodynamiques, Ie paroi arterielle maintient une structure hautement organisee et des proprietes mecaniques qui dependent directement des conditions de pression et de debit. La monocouche endotheliale developpe 2 une surface de plusieurs centaines de m a l'interface sang-tissu; elle est a la fois un organe endocrine complexe synthetisant de nombreuses proteines qui participent a l'hemostase, une surface thromboresistante et hemocompatible, une barriere de permeabilite contr6lant les echanges sang-tissus. Les cellules musculaires lisses constituent un tissu multifonctionnel, contractile, assurant la synthese des composants structuraux responsables des proprietes mecaniques de la paroi arterielle, la transmission de la force contractile, et une etonnante activite reparatrice en reponse aux agressions. Tout ceci est soumis a un ensemble complexe de communications cellulaires qui font de l'endothelium un veritable systeme recepteur pour la paroi vasculaire. Parallelement, ou a la suite de ces progres, l'angeiologie s'est progressivement affirmee comme une specialite clinique. Debordant Ie cadre de la chirurgie vasculaire, elle integre les concepts physiopathologiques au diagnostic et au traitement des maladies arterielles. De cet effort d'integration est ne cet ouvrage, cherchant a concilier les connaissances fondamentales es plus recentes et la demarche clinique.

Researchers in a number of disciplines deal with large text sets requiring both text management and text analysis. Faced with a large amount of textual data collected in marketing surveys, literary investigations, historical archives and documentary data bases, these researchers require assistance with organizing, describing and comparing texts. Exploring Textual Data demonstrates how exploratory multivariate statistical methods such as correspondence analysis and cluster analysis can be used to help investigate, assimilate and evaluate textual data. The main text does not contain any strictly mathematical demonstrations, making it accessible to a large audience. This book is very user-friendly with proofs abstracted in the appendices. Full definitions of concepts, implementations of procedures and rules for reading and interpreting results are fully explored. A succession of examples is intended to allow the reader to appreciate the variety of actual and potential applications and the complementary processing methods. A glossary of terms is provided.

It is easy to be confident that an appropriate body of advice is available to candidates about the content of an examination once you have passed it. Prospectively, the Primary and Final Examinations of the Royal College of Pathologists will appear to most to involve the assimilation of what seems at the time an inexhaustible volume of data, and the recent change in the College examination system has not diminished this concern for the majority of candidates. The guidelines for training for the new Part I examination state that this is the "major hurdle of the MRCPath" and it is clear that it will determine whether candidates are suitable for training which will permit them to practise independently as consultants after Part II. These general aims and objectives do not answer questions such as "How much do I need to know about glomerulonephritis?" or "Where do I stop with the lymphomas?" This text attempts to resolve the difficulty of knowing what standard to aim at, using College questions as its starting point. It concentrates on the essential basis of any single answer; many candidates for the new three-year examination will know more about individual topics than is stated here. However, it is the breadth of information required which is a feature of College examinations and this text should help with this problem.

Black Bodies and Transhuman Realities: Scientifically Modifying the Black Body in Posthuman Literature and Culture makes a series of valuable contributions to ongoing dialogues surrounding posthuman blackness and Afro-transhumanism. The collection explores the Black body (self) in the context of transhuman realities from a variety of literary and artistic perspectives. These points of view convey the cultural, political, social, and historical implications that frame the space of Black embodiment, functioning as sites of potentiality and pointing toward the possibility of a transcendental Black subjectivity. In this book, many questions concerning the transformation of the Black body are presented as parallels to philosophical and religious inquiries that have traditionally been addressed from a hegemonic viewpoint. The chapters demonstrate how literature, based on its historical and social contexts, contributes to broader thought about Black transcendence of subjectivity in a posthuman framework, exploring interpretations of the "old" and visions of the "new" human.

"The 747 that went up whole and came down in 876 pieces invaded every part of my life. My only consolation is that, without being able to turn around, she never saw behind her the giant hole where the rest of the aircraft should have been-an oblong oval opening to the tumbling sky, bordered by torn cables, shredded aluminum aircraft skin, sheared beams and spars, and accented with sparking severed wires. And I hope she couldn't comprehend what was actually happening if she lived long enough to ride this nearly three mile high, free-falling hell-ivator all the way down to the ocean's surface, and then sink to 140 feet below, where her body would wait to be recovered." This is a TWA Flight 800 memoir told by Mark L. Berry, a TWA pilot whose fiancee Susanne was one of the 230 passengers and crew who died when that flight exploded. 34 companion songs are developed within this book.

Walt has just turned five years old and he decided to explore the steam factory in the town of Yinkers. He meets Cryndi Crotamiter and his faithful, shape-changing friend, Zich. Unfortunately, the mayor of Yinkers wants to destroy the steam factory. It's up to the three of them to subvert ultimate destruction.

Both the aeromedical evacuation and airlift en route systems have a long and glorious history. Working separately, they provide vital services to our military. Working in tandem, they represent a precious resource in our national security framework, for they reconstitute US combat capability by evacuating and redeploying combat and combat support personnel. Yet as the US begins its military transformation and fights rapid, short-duration, high-intensity conflicts, the tandem partnership between aeromedical evacuation and the en route system must evolve to handle faster-paced requirements for moving patients both intra- and inter-theater. Examining the organizational structures, missions and governing doctrines of both systems, one finds that there is little interface between the two, and operational success is predicated largely on innovation rather than design. In future operations, innovation may not be enough to guarantee success. As a result, this author recommends an interface framework to better educate the two sides of each other's respective missions, to train together to more fully understand the synergies between the two functions, and to set the stage for better communication in the crunch to ultimately save lives.
