Unlike some other reproductions of classic texts (1) We have not
used OCR(Optical Character Recognition), as this leads to bad
quality books with introduced typos. (2) In books where there are
images such as portraits, maps, sketches etc We have endeavoured to
keep the quality of these images, so they represent accurately the
original artefact. Although occasionally there may be certain
imperfections with these old texts, we feel they deserve to be made
available for future generations to enjoy.

The high accuracy of modern astronomical spatial-temporal reference
systems has made them considerably complex. This book offers a
comprehensive overview of such systems. It begins with a discussion
of 'The Problem of Time', including recent developments in the art
of clock making (e.g., optical clocks) and various time scales. The
authors address the definitions and realization of spatial
coordinates by reference to remote celestial objects such as
quasars. After an extensive treatment of classical equinox-based
coordinates, new paradigms for setting up a celestial reference
system are introduced that no longer refer to the translational and
rotational motion of the Earth. The role of relativity in the
definition and realization of such systems is clarified. The topics
presented in this book are complemented by exercises (with
solutions). The authors offer a series of files, written in Maple,
a standard computer algebra system, to help readers get a feel for
the various models and orders of magnitude. Beyond astrometry, the
main fields of application of high-precision astronomical
spatial-temporal reference systems and frames are navigation (GPS,
interplanetary spacecraft navigation) and global geodynamics, which
provide a high-precision Celestial Reference System and its link to
any terrestrial spatial-temporal reference system. Mankind's urgent
environmental questions can only be answered in the context of
appropriate reference systems in which both aspects, space and
time, are realized with a sufficiently high level of accuracy. This
book addresses all those interested in high-precision reference
systems and the various techniques (GPS, Very Long Baseline
Interferometry, Satellite Laser Ranging, Lunar Laser Ranging)
necessary for their realization, including the production and
dissemination of time signals.
This comprehensive volume lists and describes all known eighteen
century British and Irish promptbooks. Each entry includes the
location of the copy, shelf mark, production for which the
prompt-book was prepared (theatre, date, prompter's name, if
known), the types of notes the copy contains (description of
setting, entrance notes, costume notes, ground plans, warnings,
cues, stage movement, line interpretation), and citations of any
books or articles that have dealt with the copy. The illustrations
of sample pages from some of the promptbooks listed will provide
the reader with a fuller and more accurate understanding of
eighteenth century theatre architecture and staging practices.

Die Chirurgie des Magenkarzinoms zielte in der Pionierzeit allein
auf eine Beseiti- gung des Passagehindernisses, und die Operation
galt schon als gelungen, wenn der Patient den Eingriff und die
fruhe postoperative Phase uberlebte. Eine radikale chirurgische
Therapie des Magenkarzinoms wurde erst im Verlauf dieses
Jahrhunderts durch Einfuhrung subtiler praoperativer diagnostischer
Verfah- ren, Verfeinerungen und Standardisierung chirurgischer
Techniken und nicht zu- letzt auch durch die Fortschritte von
Anasthesie und Intensivmedizin moeglich. In Anbetracht der noch
enttauschenden UEberlebensraten muss es heute unser Anliegen sein,
in interdisziplinarer Zusammenarbeit auf eine Verbesserung der
Langzeitprognose . hinzuarbeiten. Ein erster Schritt in diese
Richtung gelang nach Einfuhrung der Fiberendoskopie. Hierdurch
wurde es zum einen moeglich, die prognostisch gunstigen
Magenfruhkarzi- nome zu erkennen, aber auch beim fortgeschrittenen
Karzinom eine Strategie chirurgischer Behandlung zu entwickeln. Bei
manifesten Magenkarzinomen konkurrieren augenblicklich zwei
Behandlungs- prinzipien, namlich die stadiengerechte Chirurgie und
die Gastrektomie als Regel- operation, eventuell erganzt durch eine
systematische Lymphadenektomie. Damit sind zunachst die
chirurgischen Behandlungsmoeglichkeiten erschoepft. Eine
UEberlegenheit des einen oder anderen Konzeptes ist gegenwartig
noch nicht durch gesicherte Resultate belegt. Moeglicherweise kann
eine Verbesserung der Prognose durch die adjuvante und palliative
Chemotherapie erreicht werden. Therapieergebnisse groesserer
Kollektive fehlen jedoch auch hier noch. Dennoch darf eine
Resignation nicht aufkommen. Das Anliegen der Herausgeber ist es,
mit diesem Buch durch eine Standortbestim- mung der Diagnostik und
chirurgischen Therapie, sowie Chemotherapie und Pro- phylaxe des
Magenkarzinoms Impulse zu weiterer intensiver Forschung zu geben.
Ausgehend von den diagnostischen Moglichkeiten und den
grundlegenden pathologischen Befunden werden in diesem Buch alle
gangigen Operationsverfahren einschliesslich der palliativen
Verfahren ausfuhrlich abgehandelt. Eine neu erarbeitete
Klassifikation des Kardiakarzinoms wird angegeben. Die in den
letzten Jahren zunehmend an Bedeutung gewonnene Chemotherapie wird
ausfuhrlich dargestellt. Das Buch vermittelt dem Chirurgen und
Gastroenterologen in Klinik und Praxis einen sehr guten Uberblick
uber den derzeitigen Stand von Diagnose und Therapie des
Kardiakarzinoms.
Dieses Buch befasst sich ausschliesslich mit dem
Plattenepithelkarzinom der Speiserohre, die Einzelartikel
zahlreicher Autoren werden in 5 Abschnitten zusammengefasst:
Anatomie und Pathologie, Klinik und perioperative Massnahmen,
chirurgische Strategie und Therapiekonzept, spezielle Techniken -
Komplikationen und palliative Therapieformen. Besonderer Wert wird
in diesem Buch darauf gelegt, die heute noch sehr unterschiedlichen
Therapiestrategien und Konzepte besonders erfahrener Chirurgen auf
diesem Gebiet aufzuzeigen und eine Standardtherapieempfehlung zu
erarbeiten. Weiterhin werden aber auch Folgeerkrankungen aufgrund
von operativen Oesopaguskarzinomen aufgezeigt und diskutiert.
Gerade aber wegen der schlechten Prognose dieses Tumorleidens
werden operativ - chemotherapeutische und radiologische Massnahmen
besprochen und als wirksame Palliation empfohlen."
