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.
