This book offers an authoritative analysis of the state-of-the art
in energy and climate research and policy. It starts by describing
the current status of technologies that are expected to have an
influence on the energy systems of the future. For an adequate
evaluation, it presents the latest findings on the effects of
energy supply and consumption as well as of the emissions on both
the environment and people's health. This is followed by an
extensive discussion of the economic and social problems related to
climate change, the need for energy transitions, and other issues
that may require public investment and international agreements.
The book reviews the problem of energy policy from a global
perspective, providing readers with the technical, political,
economic and ethical background needed to understand the current
situation and work at better solutions for a sustainable, just and
prospering world.
The setting of limit values for environmental noxae is essentially based on measurements and data from single exposures. To an increasing degree, however, there are demands also to consider combined exposures. Hence, in this study, the necessity and feasability of environmental standards for combined exposures have been examined from the scientific, medical, economic, legal, sociological and philosophical/ethical perspective. Starting from effect mechanisms, criteria have been established which, in spite of the complexity of the issues, enable us to set limit values in order to achieve given environmental quality targets. This study endeavours to reveal and explain gaps in knowledge and to point to possible solutions from the scientific and medical point of view. The results should support efforts to shape a practical legal framework and viable economic procedures for environmental standards on combined exposures, taking into consideration the standards and perceptions existing in our communities.

Radioactive waste (above all highly radioactive wastes from nuclear
installations) caused by research, medicine and technology must be
disposed of safely. However both the strategies disputed for the
disposal of radioactive waste as well as concrete proposals for
choosing a location for final waste disposal are highly debatable.
An appropriate disposal must conform to both complex, technical
requirements and fulfill the radio-biological conditions to
appropriately protect man and nature. Ethical, legal and social
conditions must also be considered. An interdisciplinary team from
various, relevant fields compiled the current status-quo and
developed criteria and strategies, which on the one hand meet the
requirements of optimal warning and prevention of risk for present
and future generations, and additionally on the other hand meet the
needs of what current society agrees what is expected to be
allowed.
This study can be understood as an advanced and continuing
contribution to the corresponding scientific specialized debates,
due to its interdisciplinary treatment. At the same time it serves
as a fundamentally informing contribution to public and political
debates, offering an easily comprehensible executive summary and
precise content recommendations.
Tumour therapy depends essentially on being able to destroy the
clonogenic activity of tumour cells while keeping the damage to the
normal tissue low. Clinical experience shows that tumour response
varies greatly even if tumours with the same localisation,
clinical, and histopathological staging are compared. Some tumours
appear to be resistant to conventional radiotherapy (X-rays, y-rays
or fast electrons) or chemotherapy. In these cases new therapy
modalities are necessary. Combined therapy modalities seem to have
advan- tages for some resistant tumours; one possibility of such a
treatment is to combine radiotherapy or chemotherapy with
hyperthermia. This means that the local tumour, the tumour region
or even the whole body of the patient has to be heated to
temperatures between 40 to 45 C (in case of whole body hyperthermia
to 42 C maximal) for a certain time (usually 30-60 min are
adequate). Hyperthermia has a long tradition in medicine as a
treatment modality for various diseases. Inscriptions of the old
Egyptians and texts of the Greeks have pointed out its importance.
Usually whole body hyperthermia has been used by the induction of
fever. Local hyperthermia began around 1900 when Westermark treated
unre- sectable cervix carcinomas with hot water in a metallic coil.
By the beginning of this century an increase of radiation effects
was hy- pothesised with hypothermia and later observed. However,
only in the 1960s and 1970s were systematic investigations started
which showed radiosensitisation and chemosensitisation by
hyperthermia in cells and tissues including tumours.
The rapid growth of the world population - nearly six-fold over the
last hundred years - combined with the rising number of technical
installations especially in the industrialized countries has lead
to ever tighter and more strained living spaces on our planet.
Because ofthe inevitable processes oflife, man was at first an
exploiter rather than a careful preserver of the environment.
Environmental awareness with the intention to conserve the
environment has grown only in the last few decades. Environmental
standards have been defined and limit values have been set largely
guided, however, by scientific and medical data on single
exposures, while public opinion, on the other hand, now
increasingly calls for astronger consideration of the more complex
situations following combined exposures. Furthermore, it turned out
that environmental standards, while necessarily based on scientific
data, must also take into account ethical, legal, economic, and
sociological aspects. A task of such complexity can only be dealt
with appropriately in the framework of an inter disciplinary
group."
With a global growth in the demand for energy, secure and
economical energy supplies play a key role in human development.
Based on present-day energy supply technology, our knowledge of
available resources and the development of new forms of energy, the
study develops an assessment of future energy supplies. It takes
account of both the economic and - above all - the ethical
dimensions involved. Key Features topical issue with potentially
explosive political and economic consequences comprehensive
