This book is written for researchers and students interested in the
function and role of chemical elements in biological or
environmental systems. Experts have long known that the Periodic
System of Elements (PSE) provides only an inadequate chemical
description of elements of biological, environmental or medicinal
importance. This book explores the notion of a Biological System of
the Elements (BSE) established on accurate and precise
multi-element data, including evolutionary aspects, representative
sampling procedures, inter-element relationships, the physiological
function of elements and uptake mechanisms. The book further
explores the concept Stoichiometric Network Analysis (SNA) to
analyze the biological roles of chemical species. Also discussed is
the idea of ecotoxicological identity cards which give a first-hand
description of properties relevant for biological and toxicological
features of a certain chemical element and its geo biochemically
plausible speciation form. The focus of this book goes beyond both
classical bioinorganic chemistry and toxicology.
Modern computational techniques, such as the Finite Element Method,
have, since their development several decades ago, successfully
exploited continuum theories for numerous applications in science
and technology. Although standard continuum methods based upon the
Cauchy-Boltzmann continuum are still of great importance and are
widely used, it increasingly appears that material properties
stemming from microstructural phenomena have to be considered. This
is particularly true for inhomogeneous load and deformation states,
where lower-scale size effects begin to affect the macroscopic
material response; something standard continuum theories fail to
account for. Following this idea, it is evident that standard
continuum mechanics has to be augmented to capture lower-scale
structural and compositional phenomena, and to make this
information accessible to macroscopic numerical simulations.

Wenn es im Universum intelligente Beobachter wie uns Menschen gibt,
mssen die Naturgesetze dies ermglichen. Dieses einfache
anthropische Prinzip wird gesteigert durch die Annahme, dass die
Naturgesetze solche intelligenten Beobachter sogar zwingend
hervorbringen (das so genannte Erste und Zweite, bzw. das schwache
und starke anthropische Prinzip). Die in diesem Buch umrissenen
Gedanken begrnden auf der Basis moderner Thermodynamik ein noch
weitergehendes drittes bzw. "ganz starkes anthropisches" Prinzip:
Die Erkenntnis "Gottes" hat ebenfalls mit Eigenschaften des
Universums zu tun. Der Mensch ist prinzipiell zu zwei Formen von
Erkenntnis - naturwissenschaftlicher wie auch religiser - befhigt
und braucht auch beide, um als nicht nur als einzelne Aspekte
wissendes, sondern auch ethisch verantwortliches Wesen leben und
handeln zu knnen.
