Observing our Universe and its evolution with ever increasing
sensitivity from ground-based or space-borne telescopes is posing
great challenges to Fundamental Physics and Astronomy. The remnant
cosmic microwave background, as beautifully measured by successive
space missions COBE, WMAP, and now PLANCK, provides a unique probe
of the very early stages of our Universe. The red-shift of atomic
lines in distant galaxies, the dynamics of pulsars, the large scale
structure of galaxies, and black holes are a few manifestations of
the theory of General Relativity. Yet, today, we understand only 4%
of the mass of our Universe, the rest being called dark energy and
dark matter, both of unknown origin! A second family of space
missions is currently emerging; rather than designing ever more re
nedobservationalinstruments,physicistsandengineersseekalsotousethespaceenvironment
to perform high-precision tests of the fundamental laws of physics.
The technology required for such tests has become available only
over the course of the last decades. Clocks of high accuracy are an
example. They are based on advances in atomic and laser physics,
such as cold atoms, enabling a new generation of highly sensitive
quantum sensors for ground and space experiments. Two experiments
in space have now tested Einstein's relativity theory: * Several
decades ago, Gravity Probe A con rmed the accuracy of the

17 readable articles give a thorough and self-contained overview of
recent developments in relativistic gravity research. The subjects
covered are: gravitational lensing, the general relativistic n-body
problem, observable effects in the solar system, gravitational
waves and their interferometric detection, very-long-baseline
interferometry, international atomic time, lunar laser- ranging
measurements, measurement ofthe gravitomagnetic field of the Earth,
fermion and boson stars and black holes with hair, rapidly rotating
neutron stars, matter wave interferometry, and the laboratory test
of Newton's law of gravity.Any scientist interested in
experimentally or observatio- nally oriented relativistic gravity
will read the book with profit. In addition, it is perfectly suited
as a complementary text for courses on general relativity and
relativistic astrophysics.

The topic of the 29th Hosbach Colloquium Energy Transduction in
Biological Membranes is one of the most formidable problems in
biology. Its solu- tion in molecular terms has proved to be a very
difficult task for a whole generation of biochemists. The Mosbach
Colloquia had so far not yet covered this subject. In for- mer
Mosbach Colloquia some contributions were closely related, such as
the lecture by E. C. Slater on the mitochondrial respiratory chain,
presented 25 years ago. A broader coverage of this subject was
given in the Mosbach Colloquia on Biochemistry of Oxygen in 1968,
and on Inhib- itors: Too ls in Ce II Research in 1 969, which
contained several lectures related to bioenergetics. Today progress
and understanding of the energy transduction in biolog- ical
membranes had advanced to the stage where we can formulate reli-
able theories on many facets of the energy transduction process. On
the other hand, the primary energy conservation steps are as
contro- versial as ever and challenge the field for an all-out
effort for re- solving these burning problems. The 29th !1osbach
Colloquium has given a broad and vivid picture of this situation,
illustrating the progress and also the controversial problems
currently debated.
This book uses numerous examples to describe the current
opportunities and risks of air freight against the backdrop of
stagnating transport volumes since the financial crisis in 2008. It
shows what impact these developments have had on those involved, in
particular shippers, airlines, airports and freight forwarders. The
application-oriented presentation also provides an insight into the
design of complex supply chains and the areas of tension in which
the players in air freight operate.
Dieses Buch beschreibt anhand zahlreicher Beispiele die
gegenwartigen Chancen und Risiken der Luftfracht vor dem
Hintergrund stagnierender Transportmengen seit der Finanzkrise im
Jahr 2008. Es zeigt, welche Auswirkungen diese Entwicklungen auf
die Beteiligten haben, insbesondere auf Versender,
Fluggesellschaften, Flughafen und Spediteure. Die
anwendungsorientierte Darstellung ermoeglicht zudem einen Einblick
in die Gestaltung komplexer Lieferketten und die Spannungsfelder,
in denen sich die Akteure der Luftfracht bewegen.
Das vordringliche Problem in der Gynakologie ist das
Uteruscarcinom, seine Verhiitung, seine friihzeitige Erkennung und
seine Bekampfung. Un geheuer viel ist auf diesen Gebieten
gearbeitet und auch manches erreicht worden. In gut geleiteten
gynakologischen Kliniken werden heute fast 1/3 aller
Carcinomkranken und mehr als die Halfte der guten Carcinome dauernd
geheilt. Die geheilten Carcinompatienten brauchen den Arzt nlcht
mehr, wohl aber das groBe Heer der ungeheilten, mit denen sich
diese Monographie befaBt. Was diese Frauen zu leiden haben, welche
Belastung sie fiir ihre Umgebung, fiir das Krankenhaus, fiir die
Versicherungstrager und fiir die Offentlichkeit darstellen, kann in
seinem ganzen Umfang nur der ermessen, der taglich mit solchen
Frauen umzugehen hat. Die Carcinomstationen der groBen
Frauenkliniken sind der Ort, wo diese Frauen zusammenstromen und
Linderung ihrer Leiden suchen. So ist das in dieser Schrift
zusammengetragene Material in der Universitats-Frauen klinik Berlin
gesammelt. Es verdient deswegen Beachtung, weil es die vor handene
Ansicht beseitigt, daB der Gebarmutterkrebs den Knochen nicht
befallt. Wie der Leser sehen wird, geht das Carcinom yom
Parametrium aus in die seitliche Beckenwand, von den
retroperitonealen Drusen aus in die Wirbel saule und in das
Kreuzbein. Rontgenbilder und Sektionspraparate haben uns dies so
oft bewiesen, daB wir sagen diirfen, daB es sich hier um typische
Krank heitsbilder handelt, die genau so zur Klinik der
vorgeschrittenen Gebar muttercarcinome gehoren, wie z. B. das
Befallensein von Blase und Rectum. Der eine von uns (PHILIPP) hat
in einigen Arbeiten der letzten Jahre (Zbl. Gynak."
