Rectal cancer is one of the most prevalent cancers world-wide. It
is also a paradigm for multimodal management, as the combination of
surgery, chemotherapy and radiotherapy is often necessary to
achieve the optimal outcome. Recently, international experts met in
Heidelberg, Germany to discuss the latest developments in the
management of rectal cancer, including the anatomic and pathologic
basis, staging tools, surgical concepts including fast-track
surgery and laparoscopic resection, functional outcome after
surgery and the role of radio- and chemotherapy. This monograph
summarizes this meeting and gives an extensive overview of the
current concepts in management of rectal cancer.
Processes of acidification or alkalization of soils are treated,
taking the qualitative changes in soil chemistry into
consideration. Following a theoretical background of ecosystem
proton budgets, the application for assessing external and internal
acid loads are demonstrated. The chemistry of organic matter and
the oxides of aluminum, iron, and manganese are treated in the
context of being sources and sinks for acid loads in soils. Special
attention is payed to the assessment of solubility and reaction
kinetics of aluminous minerals. The formation of toxic elements in
soil solution resulting from the solubilization of inorganic oxides
as well as aspects of changes in the nutrient status of soils,
changes of fertility and processes leading to a transfer of acidity
from soils to surface are discussed.
This volume is based on a workshop on "Effects of accumulation of
air pollutants in forest ecosystems'; held in GOttingen, Federal
Republic of Germany, from May 16-18, 1982. This work'shop was
initiated and sponsored by the Environmental Agency of the Federal
Republic of Germany (project officer: Dr. J. Pankrath) as part of a
research contract (project leader: Dr. B. Ulrich). THE PROBLEM SEEN
UNDER THE ASPECT OF ADMINISTRATION The problem of forest damage
caused by air pollution is not new in Europe. Already in 1983 a
comprehensive report from Schroeder and Reuss about vegetation
damages by fume in the Harz mountains was published. In 1923, Prof.
Dr. Julius Stocklasa of the Bohemian Technical Highschool in Prague
was concerned with research of toxical effects of sulphur dioxide
in his publication "The damage of vegetation by flue gas and
exhalations of facili ties". This comprehensive and instructive
work concludes with the sentence: "It is already high time for the
governments of all cultural states to take legal, police and
private measures in order to prevent damage by flue gases". In the
neighbourhood of industries with high gaseous and dust emissions
damages have been shown to occur for a long timei these deleterious
effects have influenced the growth of trees and in extreme cases
have even caused their early death.
The inclusion of forests as potential biological sinks in the Kyoto
Protocol to the United Nations Framework Convention on Climate
Change (UNFCCC) in 1997 has attracted international attention and
again has put scientific and political focus on the world's
forests, regarding their state and development. The international
discus sion induced by the Kyoto Protocol has clearly shown that
not only the tropical rain forests are endangered by man's
activities, but also that the forest ecosystems of boreal,
temperate, mediterranean and subtropical regions have been
drastically modified. Deforestation on a large scale, burning,
over-exploitation, and the degra dation of the biological diversity
are well-known symptoms in forests all over the world. This
negative development happens in spite of the already existing
knowledge of the benefits of forests on global energy and water
regimes, the biogeochemical cycling of carbon and other elements as
well as on the biological and cultural diversity. The reasons why
man does not take care of forests properly are manifold and complex
and there is no easy solution how to change the existing negative
trends. One reason that makes it so difficult to assess the impacts
of human activity on the future development of forests is the large
time scale in which forests react, ranging from decades to
centuries."

147 sorgfaltig ausgewahlte Arbeiten zeigen das breite Spektrum der
deutschsprachigen chirurgischen Forschung auf. Sowohl klinische als
auch Grundlagenforschung sind berucksichtigt. Der hochaktuelle Band
erscheint noch vor der Prasentation der Ergebnisse bei der 121.
Jahrestagung der Deutschen Gesellschaft fur Chirurgie."
A comprehensive exploration of woodworking in the ancient Roman
world  “A valuable overview in English of how the Romans
used wood in objects great and small, humble and
grand.”—Richard F. Liebhart, American Journal of Archaeology
 This book presents an authoritative and detailed survey of
the art of woodworking in the ancient Roman world. Illustrated with
over 200 line drawings and photographs, Roman Woodworking covers
topics such as the training and guild memberships of Roman
carpenters, woodworking tools and techniques, the role of timber in
construction and the availability of trees, and interior woodwork
and furniture making. It also includes an extensive glossary of
fully defined terms. Â This comprehensive book displays the
accomplishment of the Roman woodworkers and their high skill and
knowledge of materials and tools. Ulrich helps bring to light the
importance of wooden projects and structures in Roman daily life
and provides a wealth of information not only for classicists but
also for those interested in the history of technology and the
history of woodworking.
