These Proceedings contain both oral and poster contributions to the
first interna tional conference" Field Screening Europe -
Strategies and Techniques for On-Site Investigation and Monitoring
of Contaminated Soil, Water and Air," held in Karls ruhe September
29 - October 1, 1997. Environmental monitoring and the assessment
of chemical contaminations are be coming more and more important.
The integrated study of environmental con tamination in the field
is a rather recent approach. "Field screening" indicates such field
analytical tools, (quick) methods and strategies for on-site or
in-situ environmental analysis and assessment of contamination. The
classical strategy for investigating contaminants consists of the
following steps: site studies, sampling, sample transport to the
laboratory, sample preparation, and analysis. This strategy is
rather expensive and time consuming. Some investiga tions,
including sample preparation, may last several days. In many cases,
the results must be available immediately and are of importance for
further decisions. Field screening is an alternative or complement
to this strategy that attempts to be cheaper and faster and may
achieve the same quality of results. The most important argument
for field analytical methods is that the superior accuracy and high
costs of laboratory methods are disproportional to the possibility
of arti facts from sampling and errors originating from spatial
variations of contaminants."
"Field screening" indicates field analytical tools, and (quick)
methods and strategies for on-site or in-situ environmental
analysis and assessment of contamination. "Field screening"
includes not only field analytical methods, such as mobile
laboratories, portable analyses, detectors, sensors, or noninvasive
techniques, but also reconnaissance strategies and problems of
measurement in heterogeneous media, using, among others, new
geotechnical and geophysical instruments.
This volume contains both oral and poster contributions to the
Second International Conference on Strategies and Techniques for
the Investigation and Monitoring of Contaminated Sites, "Field
Screening Europe 2001," held in Karlsruhe, May 14 - May 16, 2001.
As an integrated study of environmental contamination, "field
screening" has become a more and more important part of
environmental monitoring and the assessment of chemical
contaminations. Recent developments are presented in these
proceedings.
Audience Environmental engineers, geo-scientists, chemists,
biologists, soil scientists, hydrologists and geophysicists.
The Workshop on Parameter Identification and Inverse Problems in
Hydrology, Geology and Ecology, Karlsruhe, April 10-12, 1995, was
organized to bring to gether an interdisciplinary group drawn from
the areas of science, engineering and mathematics for the following
purposes: - to promote, encourage and influence more understanding
and cooperation in the community of parameter identifiers from
various disciplines, - to forge unity in diversity by bringing
together a variety of disciplines that attempt to understand the
reconstruction of inner model parameters, un known nonlinear
constitutive relations, heterogeneous structures inside of
geological objects, sources or sinks from observational data, - to
discuss modern regularization tools for handling improperly posed
pro blems and strategies of incorporating a priori knowledge from
the applied problem into the model and its treatment. These
proceedings contain some of the results of the workshop,
representing a bal anced selection of contributions from the
various groups of participants. The reviewed invited and
contributed articles are grouped according to the broad headings of
hydrology, non-linear diffusion and soil physics, geophysical
methods, mathematical analysis of inverse and ill-posed problems
and parallel algorithms for inverse problems. Some of the issues
adressed by the articles in these proceedings include the rela tion
between least squares and direct formulations of inverse problems
for partial differential equations, nonlinear regularization,
identification of nonlinear consti tutive relations, fast parallel
algorithms for large scale inverse problems, reduction of model
structures, geostatistical inversion techniques.

These selections provide a brief but comprehensive introduction to
Fichte's philosophical system and his place in the history of
German Idealism. In addition to some of Fichte's most influential
texts, such as the First and Second Introductions to the
Wissenschaftslehre and The Basis of Our Belief in a Divine
Governance of the World, Breazeale has translated, for the first
time into English, several other writings from the same period,
including Attempt at a New Presentation of the Wissenschaftslehre,
Other short essays, including Fichte's replies to the charge of
atheism, extend the discussions of the Introductions and respond to
criticisms. Breazeale's substantial Introduction supplies the
context needed for a sound appreciation of Fichte's enterprise and
achievement.
Contents include a translator's introduction, selected
bibliography, note on the text, and Fichte's The Vocation of Man --
Book One: Doubt, Book Two: Knowledge, and Book Three: Faith.
