Throughout its history, the discipline of ecology has always been
profoundly entangled with the history of space and place. On the
one hand, ecology is a field science that has thrived on the study
of concrete spatial entities, such as islands, forests or rivers.
These spaces are the workplaces in which ecological phenomena are
identified, observed and experimented on. They provide both
epistemic opportunities and constraints that structure the agenda
and the analytical sensibilities of ecological researchers. On the
other hand, ecological knowledge and practices have become
important resources through which spaces and places are classified,
delineated, explained, experienced and managed. The impact of these
activities reaches far beyond the realms of the ecological
discipline. Many ecological concepts such as "biotopes,"
"ecosystems" and "the biosphere" have become entities that widely
resonate in public life and policy making. This book explores the
mutual entanglement between space and knowledge-making in the
history of ecology. Its first goal is to explore to which extent a
spatial perspective can shed new light on the history of ecological
science. Second, it uses ecology as a critical site to gain broader
insights into the history of the environment in the nineteenth and
twentieth centuries. Via a series of case studies - discussing
topics that range from ecological field stations in the
early-twentieth century Caribbean over wisent breeding in Nazi
Germany to computer modelling in North American deserts - the book
offers a tour through the changing landscapes of modern ecology.
The book provides an in-depth discussion on the human nature
concept from different perspectives and from different disciplines,
analyzing its use in the doping debate and researching its
normative overtones. The relation between natural talent and
enhanced abilitiesis scrutinized within a proper conceptual and
theoretical framework: is doping to be seen as a factor of the
athlete s dehumanization or is it a tool to fulfill his/her
aspirations to go faster, higher and stronger? Which
characteristics make sports such a peculiar subject of ethical
discussion and what are the, both intrinsic and extrinsic, moral
dangers and opportunities involved in athletic enhancement? This
volume combines fundamental philosophical anthropological
reflection with applied ethics and socio-cultural and empirical
approaches. Furthermore guidelines will be presented to decision-
and policy-makers on local, national and international levels.
Zooming in on the intrinsic issue of what is valuable about our
homo sapiens biological condition, this volume devotes only scant
attention to the specific issue of natural talent and why such
talent is appreciated so differently than biotechnological origins
of ability. In addition, specific aspects of sports such as its
competitive nature and its direct display of bodily prowess provide
good reason to single out the issue of natural athletic talent for
sustained ethical scrutiny. "
During the past several years there has been a shortage of flight
opportunities for biological and medical projects. And those that
were available usually had severe restrictions on instrumentation,
number of subjects, duration, time allotted for performing the
experiments, a possibility for repetition of experiments. It is our
hope and expectation that this will change once the international
Space Station is in full operation. The advantages of a permanent
space station, already demonstrated by the Russian Mir station, are
continuous availability of expert crew and a wide range of
equipment, possibility of long-term experiments where this is
waranted, increased numbers of subjects through larger laboratory
space, proper controls in the large 1-G centrifuge, easier
repeatability of experiments when needed.
The limited number of flight opportunities during recent years
probably explains why it has taken so long to acquire a sufficient
number of high quality contributions for this seventh volume of
Advances in Space Biology and Medicine. While initially the series
wassailed at annually appearing volumes, we are now down to a
biannual appearance. Hopefully, it will be possible to return to
annual volumes in the future when results from space station
experimentation at beginning to pour in.
The first three chapters of this volume deal with muscle. Fejtek
and Wassersug provide a survey of all studies on muscle of rodents
flown in space, and include an interesting demography of this
aspect of space research. Riley reviews our current knowledge of
the effects of long-term spaceflight and re-entry on skeletal
muscle, and considers the questions still to be answered before we
can be satisfied that long-term space missions, such as on the
space station, can be safely undertaken. Stein reviews our
understanding of the nutritional and hormonal aspects of muscle
loss in spaceflight, and concludes that the protein loss in space
could be deleterious to health during flight and after return.
Strollo summarizes our understanding of the major endocrine systems
on the ground, then considers what we know about their functioning
in space, concluding that there is much to be learned about the
changes taking place during spaceflight. The many problems of
providing life support (oxygen regeneration and food supply) during
extended stay on the Moon, on Mars, or in space by means of plant
cultivation are discussed by Salisbury. The challenges of utilizing
electrophoresis in microgravity for the separation of cells and
proteins are illustrated and explained by Bauer and colleagues.
Finally, the chapter on teaching of space life sciences by Schmitt
shows that this field of science has come of age, but also that its
multidisciplinary character poses interesting challenges to
teaching it.
The use of shallow geothermal energy (SGE) systems to acclimatize
buildings has increased exponentially in the Netherlands and
worldwide. In certain areas, SGE systems are constructed in
aquifers also used for drinking water supply raising the question
of potential groundwater quality impact. Impacts of Shallow
Geothermal Energy on Groundwater Quality provides a hydrochemical
and geomicrobial overview of the effects of ground source heat
pumps and aquifer thermal energy storage. The area is investigated
with field and laboratory experiments, and reactive transport
models, showing that shallow geothermal energy systems can
influence groundwater quality in a number of ways. Most prominent
in open ground source heating systems operating at low temperature
(<20 DegreesC) is the physical mixing of deep and shallow
groundwater of different quality distorting the natural water
quality stratification in aquifers. At a temperature of 25 DegreesC
and beyond certain trace elements were observed to mobilize in
laboratory experiments, and beyond 40 DegreesC redox conditions
change significantly while the microbial community shift towards a
thermophilic community. Based on the results of this research,
guidelines are presented for monitoring and permitting of SGE
systems. The book is a useful resource for regulators of these
systems, water companies and installers of the SGE systems. Author:

The impact of the European Community and European Community law on
taxation is becoming increasingly important. EC law influences not
only national tax law but also tax treaties. This book focuses on
the question of whether anti-abuse provisions in tax treaties may
be in conflict with EC law, especially the fundamental freedoms
contained in the EC Treaty. This issue is dealt with from the
perspective of Austria, France, Germany, Italy, The Netherlands,
Spain and the United Kingdom. Though most problems arise with
regard to the limitation on benefits clauses contained in the tax
treaties concluded between EC Member States and the United States,
the book also addresses the compatibility with EC law of other
anti-abuse clauses and assesses the consequences of a possible
conflict. EUCOTAX (European Universities Cooperating on Taxes) is a
network of fiscal institutes of European universities - nine in
1998. This network aims at initiating and co-ordinating both
comparative education and comparative research on taxation. The
comparative education is structured by various means, e.g.
organizing winter courses and guest lectures. Comparative research
is realised by means of joint research projects, international
conferences and exchange of researchers from various countries.

On Christmas Eve, New York cop John McClane (Bruce Willis) is
visiting his estranged wife Holly (Bonnie Bedelia) in Los Angeles,
where she works. They are attending a party at Holly's high-rise
office block when terrorists, led by the suave Hans Gruber (Alan
Rickman) break in, taking everyone hostage. McClane manages to
evade capture, however, and sets out to rescue his wife and the
other prisoners. It is not long before he is running barefoot over
shattered glass (ouch!) in a sweaty vest, muttering 'Yippy kay aye'
as he dispatches the baddies with bullets and a certain earthy wit.
This fourth volume in the series, dedicated entirely to the results
of the first European study of the effects of long-term confinement
and isolation. The volume continues to attempt to fulfill the aim
of this series, to bring the findings and accomplishments in the
field of space biology and medicine to a wider group of scientists
than merely the relatively small group of biologists and
physiologists currently involved in space experimentation.
The contributions are not only nicely spread geographically with
three chapters from the United States, two each from Russia,
Europe, and Japan, they also offer a wide range of topics in the
field, covering humans, animals, plants, cells, and even potential
extraterrestrial beings.
As before, not only problems investigated and results obtained are
reviewed, but also some of the technical aspects peculiar to this
field are treated. An example in this volume is the chapter on
virtual environments by Ellis, which is meant to help investigators
understand the opportunities that these techniques might offer for
future investigations.
In view of the limitations on flight opportunities and the
constraints still inherent in orbital experimentation, it is also
important to consider the information that can be obtained from
studies on the ground. In addition to simulation studies like bed
rest for human subjects (see the chapter by Edgerton et al. on
neuromuscular adaptation), tail suspension of rats, and plants on a
clinostat (see the chapter by Masuda et al.), there is the
interesting possibility of using gravitropic mutants for studying
the effects of weightlessness on plant growth as described by
Takahashi and Suge.
Two chapters are devoted to a review of the results on rats flown
on nine Cosmos biosatellite flights between 1973 and 1989: the
chapter by Krasnow deals with the neuromorphological effects of
micro- and hypergravity; that by Popova and Grigoriev with the
metabolic effects of spaceflight. The effects of weightlessness on
heart and lung function in humans are reviewed in detail by
Bonde-Petersen and Linnarson.
While the study of humans, animals, and plants in spaceflight have
taught us much about the effects of the space environment on living
organisms, we still have a very limited understanding of the
mechanisms operating in these effects. The chapter by Rijken et al.
on the effects of gravity on the cellular response to epidermal
growth factor demonstrates how, by a judicious use of experiments
on the ground and in sounding rockets, the mechanism of a
microgravity effect on cell growth could be unravelled.
The question whether there is intelligent life elsewhere in the
universe has intrigued mankind for a long time. In the chapter by
Coulter et al. on NASA's High Resolution Microwave Survey the
project to search for the existence of such life is described. The
postscript to this chapter tells how through an unfortunate
decision of the U.S. Congress this project after a successful start
is threatened with an untimely ending.

In dem Band XV /2 des Handbuches der medizinischen Radiologie
wurden bei der klini- schen Nuklearmedizin bewuBt einige Kapitel
herausgenommen, urn die weitere Entwicklung auf diesen Gebieten
abzuwarten. Der vorliegende Band beinhaltet diese Kapitel. Die
nuklear- medizinische Herz- und Kreislaufdiagnostik hat sich in der
Zwischenzeit zu einem der drei wichtigsten diagnostischen Gebiete
der Nuklearmedizin entwickelt. Dies nicht nur im Hin- blick auf die
Aussagemoglichkeit sondern auch fur die Anzahl der zu
untersuchenden Patien- ten. Mit dieser Entwicklung ist eindeutig
bewiesen, daB die ExistenzHihigkeit der Nuklearme- dizin trotz
erheblicher Leistungen anderer, auch bildgebenden Verfahren
gewahrleistet ist. Die nuklearmedizinische Herz- und
Kreislaufdiagnostik, die sich von den ersten Anfangen an, zunachst
nur an einzelnen Zentren und hier auch langsam entwickelt hat, ist
in ihrer Bedeutung in den letzten lahren sprunghaft angestiegen.
Hinzu kommt allerdings, daB das Untersuchungsverfahren innerhalb
der nuklearmedizinischen Technik eines der schwierigsten und
aufwendigsten ist und daB die Anforderungen an den Arzt im Hinblick
auf seine diagno- stischen Aussagen eine groBe Erfahrung verlangen.
Aus diesen Grunden ist der Thematik in dies em Band erheblicher
Raum eingeraumt worden. Die einze1nen Kapitel demonstrieren die
Entwicklung, die Effizienz und die diagnostischen
Aussagemoglichkeiten. Gleiches gilt fur die nuklearmedizinischen
Untersuchungsverfahren fur die Padiatrie. Durch die standige
Verbesserung der Radiopharmaka und der MeBgerateeinheiten weitet
sich dieses Gebiet mehr aus und bringt tatsachlich richtig in
Anwendung gebracht erhebliche Fortschritte fUr die
Differentialdiagnostik bei Erkrankungen im Sauglings- und
Kindesalter.
The long-awaited companion title to MY MONSTER BOYFRIEND is finally

ghosts, werewolves, demons, and other horrors that go bump in the
night. No bedside table can be complete without this collection of
spicy tales from the dark side in the tried-and-true Smut Peddler
style: broadly diverse, sex-positive, consent-driven, and tons of
fun!
When we think of sites of animal research that symbolize modernity,
the first places that come to mind are grand research institutes in
cities and near universities that house the latest in equipment and
technologies, not the surroundings of the bird's nest, the octopus'
garden in the sea, or the parts of inland lakes in which freshwater
plankton reside. Yet during the late nineteenth and early twentieth
centuries, a group of zoologists began establishing novel, indeed
modern ways of studying nature, propagating what present-day
ecologists describe as place-based research. Raf De Bont's Stations
in the Field focuses on the early history of biological field
stations and the role these played in the rise of zoological
place-based research. Beginning in the 1870s, a growing number of
biological field stations were founded-first in Europe and later
elsewhere around the world - and thousands of zoologists received
their training and performed their research at these sites. Through
case studies, De Bont examines the material and social context in
which field stations arose, the actual research that was produced
in these places, the scientific claims that were developed there,
and the rhetorical strategies that were deployed to convince others
that these claims made sense. From the life of parasitic
invertebrates in northern France and freshwater plankton in
Schleswig-Holstein, to migratory birds in East Prussia and pest
insects in Belgium, De Bont's book is a fascinating tour through
the history of studying nature in nature.
This book provides a comprehensive overview of core concepts and
technological foundations for continuous engineering of Web
streams. It presents various systems and applications and includes
real-world examples. Last not least, it introduces the readers to
RSP4J, a novel open-source project that aims to gather community
efforts in software engineering and empirical research. The book
starts with an introductory chapter that positions the work by
explaining what motivates the design of specific techniques for
processing data streams using Web technologies. Chapter 2 briefly
summarizes the necessary background concepts and models needed to
understand the remaining content of the book. Subsequently, chapter
3 focuses on processing RDF streams, taming data velocity in an
open environment characterized by high data variety. It introduces
query answering algorithms with RSP-QL and analytics functions over
streaming data. Chapter 4 presents the life cycle of streaming
linked data, it focuses on publishing streams on the Web as a
prerequisite aspect to make data findable and accessible for
applications. Chapter 5 touches on the problems of benchmarks and
systems that analyze Web streams to foster technological progress.
It surveys existing benchmarks and introduces guidelines that may
support new practitioners in approaching the issue of continuous
analytics. Finally, chapter 6 presents a list of examples and
exercises that will help the reader to approach the area, get used
to its practices and become confident in its technological
possibilities. Overall, this book is mainly written for graduate
students and researchers in Web and stream data management. It
collects research results and will guide the next generation of
researchers and practitioners.
It is fashionable in professional circles to deplore the difficulty
of intellectual discourse between "academicians" - men of letters,
researchers, rationalist- and "practitioners" - surgeons,
radiologists, physical therapists. How benefi cial it would be if
educated non-academicians could speak intelligently about t-tests
and chi-square tests and men of academia could appreciate the
travail, spirit, and needs of a busy office and practice Even this
suspected gap between "two cultures" came very near together in the
wonderful town of Groningen (The Netherlands) as wise men from both
practice and scholarship gathered to talk about the unfathomables
of the temporomandibular joint. There were keen discussions about
the intense bio logical changes which occur about the complex
temporomandibular joint after excessive use or injury. These papers
were followed by talks outlining the experiences of those involved
in the imaging and non-surgical and surgical management of patients
who were enduring such changes. The pitch and interchange of
opinions and evidence as to why a disc or its position could effect
little or profound disturbance of the temporomandibular apparatus
were en lightening to each who listened - and thought. And even
more sobering was to hear the report of a well-documented, multiple
decades long study of a large number of patients with
osteoarthrosis and internal derangement which defined a natural
course and eventual end of the disease. With this understanding,
one is now faced with the obvious question of how much treatment
patients with osteoarthrosis really require."
