Magnetic Functions Beyond the Spin-Hamiltonian
Using the spin-Hamiltonian formalism the magnetic parameters are introduced through the components of the Lambda-tensor involving only the matrix elements of the angular momentum operator. The energy levels for a variety of spins are generated and the modeling of the magnetization, the magnetic susceptibility and the heat capacity is done. Theoretical formulae necessary in performing the energy level calculations for a multi-term system are prepared with the help of the irreducible tensor operator approach. The goal of the programming lies in the fact that the entire relevant matrix elements (electron repulsion, crystal field, spin-orbit interaction, orbital-Zeeman, and spin-Zeeman operators) are evaluated in the basis set of free-atom terms. The modeling of the zero-field splitting is done at three levels of sophistication. The spin-Hamiltonian formalism offers simple formulae for the magnetic parameters by evaluating the matrix elements of the angular momentum operator in the basis set of the crystal-field terms. The magnetic functions for dn complexes are modeled for a wide range of the crystal-field strengths.

Life in the Universe : Expectations and Constraints
Energy, chemistry, solvents, and habitats -- the basic elements of living systems - define the opportunities and limitations for life on other worlds. This class-tested text examines each of these parameters in crucial depth and makes the argument that life forms we would recognize may be more common in our solar system than many assume. It also considers, however, exotic forms of life that would not have to rely on carbon as basic chemical element, solar energy as a main energy source, or water as primary solvent. Finally the question of detecting bio- and geosignature of such life forms is discussed, ranging from Earth environments to deep space. While speculative considerations in this emerging field of science cannot be avoided, the authors have tried to present their study with the breadth and seriousness that a scientific approach to this issue requires. They seek an operational definition of life and investigate the realm of possibilities that nature offers to realize this very special state of matter and avoid scientific jargon wherever possible to make this intrinsically interdisciplinary subject understandable to a broad range of readers.

The contributions are held together by the common goal to understand better the origin of life, its evolution and possible existence outside the Earth's realm.
Le dépistage du cancer bronchique : De l'espoir à la réalité = Lung cancer screening : From hope to reality
An ambitious program has been launched in terms of research, diagnosis, prevention, and screening. Among cancers, the leading cause of cancer death is lung cancer. This disease, so closely linked to behavioral habits, both focuses and encapsulates the problem. Despite constant progress in treatment, the prognosis remains bleak, explaining the fatalistic impression left by the last decade. While significant efforts were being made in screening for other cancer sites, lung cancer remained in the shadows, with studies showing limited effectiveness in this approach. The advent of spiral CT scanning has revolutionized the field, giving rise to new hope alongside anti-smoking campaigns. Autofluorescence endoscopy, by enabling the diagnosis of pre-neoplastic lesions, completes an arsenal that finally allows us to envision an effective, combined strategy. This book brings together all the elements relating to screening and early diagnosis. The road from hope to reality is long, but we must acknowledge that, for the first time, we know it exists.
L'astrofilo moderno = The modern amateur astronomer
In less than two decades, amateur astronomy has changed its face. The reason, of course, is technological progress. Cheap but high-quality telescopes, computer-controlled "go-to" mounts, autoguiders, CCD cameras, video cameras and (as always) computers and the Internet are just some of the elements that revolutionized 21st century astronomy. Not only have they made amateur astronomy more "friendly" and fun, but they have also greatly expanded the potential of the amateur astronomer. Martin Mobberley first tackles the basic issues and then analyzes in depth what tools are available on the market. From here he starts to review the revolutionary possibilities that open up for amateur astronomers, from imaging, to spectroscopy, to photometry, to the surveillance of Near-Earth objects - comets and asteroids that can come dangerously close to the Earth.
Lagrangian Transport in Geophysical Jets and Waves : The Dynamical Systems Approach
This book provides an accessible introduction to a new set of methods for the analysis of Lagrangian motion in geophysical flows. These methods were originally developed in the abstract mathematical setting of dynamical systems theory, through a geometric approach to differential equations. Despite the recent developments in this field and the existence of a substantial body of work on geophysical fluid problems in the dynamical systems and geophysical literature, this is the first introductory text that presents these methods in the context of geophysical fluid flow. The book is organized into seven chapters; the first introduces the geophysical context and the mathematical models of geophysical fluid flow that are explored in subsequent chapters. The second and third cover the simplest case of steady flow, develop basic mathematical concepts and definitions, and touch on some important topics from the classical theory of Hamiltonian systems. The fundamental elements and methods of Lagrangian transport analysis in time-dependent flows that are the main subject of the book are described in the fourth, fifth, and sixth chapters. The seventh chapter gives a brief survey of some of the rapidly evolving research in geophysical fluid dynamics that makes use of this new approach. Related supplementary material, including a glossary and an introduction to numerical methods, is given in the appendices.
JDF : Process Integration, Technology, Product Description
The arrival of PDF has successfully optimized certain elements of the production workflow – the next challenge facing the print media industry is to resolve the problem of non-networked software packages that exist in isolation. Businesses today need to identify process inefficiencies to ensure the successful process integration of the entire value added chain. The PDF document format and the vendor-independent JDF (Job Definition Format) provide the technical platform for devising new, fully integrated workflow solutions. Networking decisions involve virtually every department of a print service provider and lay down the direction of the company over the long term. These decisions offer opportunities, but they also harbor risks. If businesses are to make the right investment decisions, it is vital they have extensive background information on technical and business management issues. The authors provide focused information for decision makers looking for support in implementing networking projects successfully. This book is couched in straightforward language, explains and highlights relevant terms, and provides readers with numerous practical illustrations, graphics and checklists that they can apply to real-life applications.

Computational Aspects of General Equilibrium Theory : Refutable Theories of Value
This monograph presents a general equilibrium methodology for microeconomic policy analysis. It is intended to serve as an alternative to the now classical, axiomatic general equilibrium theory as exposited in Debreu`s Theory of Value (1959) or Arrow and Hahn`s General Competitive Analysis (1971). The methodology proposed in this monograph does not presume the existence of market equilibrium, accepts the inherent indeterminancy of nonparametric general equlibrium models, and offers effective algorithms for computing counterfactual equilibria in these models. It consists of several essays written over the last decade, some with colleagues or former graduate students, and an appendix by Charles Steinhorn on the elements of O-minimal structures, the mathematical framework for our analysis.
Computational Acoustics of Noise Propagation in Fluids - Finite and Boundary Element Methods
Among numerical methods applied in acoustics, the Finite Element Method (FEM) is normally favored for interior problems whereas the Boundary Element Method (BEM) is quite popular for exterior ones. That is why this valuable reference provides a complete survey of methods for computational acoustics, namely FEM and BEM. It demonstrates that both methods can be effectively used in the complementary cases. The chapters by well-known authors are evenly balanced: 10 chapters on FEM and 10 on BEM. An initial conceptual chapter describes the derivation of the wave equation and supplies a unified approach to FEM and BEM for the harmonic case. A categorization of the remaining chapters and a personal outlook complete this introduction. In what follows, both FEM and BEM are discussed in the context of very different problems.

Comparative genomics ; Vol.15 : Using Fungi as Models
Fungal comparative genomics started in 2000 by the genome sequencing of several yeast species other than the canonical Saccharomyces cerevisiae. Since then, over 30 fungal genome sequences have become available. This set represents a total evolutionary divergence comparable to that between vertebrates and arthropods, but also contains closely related genomes. This volume describes how we can use this set of genomes to trace large and small-scale events in genome evolution, to extract information about highly conserved and less conserved sequence elements, and to develop novel methods in genomics that will have an impact on genomics at large.
