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.

Issues in Bioinvasion Science contains key contributions of this conference. The themes included cut across different aspects of non-native species invasions. This volume is essential reading for anyone seeking an understanding of non-native species invasions.
Complex Computing-Networks : Brain-like and Wave-oriented Electrodynamic Algorithms
This book uniquely combines new advances in the electromagnetic and the circuits&systems theory. It integrates both fields regarding computational aspects of common interest. Emphasized subjects are those methods which mimic brain-like and electrodynamic behaviour; among these are cellular neural networks, chaos and chaotic dynamics, attractor-based computation and stream ciphers.
Communicating Science in Social Contexts : New models, new practices
Science communication, as a multidisciplinary field, has developed remarkably in recent years. It is now a distinct and exceedingly dynamic science that melds theoretical approaches with practical experience. Formerly well-established theoretical models now seem out of step with the social reality of the sciences, and the previously clear-cut delineations and interacting domains between cultural fields have blurred. Communicating Science in Social Contexts examines that shift, which itself depicts a profound recomposition of knowledge fields, activities and dissemination practices, and the value accorded to science and technology.
Climate of the middle : Understanding climate change as a common challenge
This book presents a multidisciplinary perspective to increase our understanding of climate policies that are rooted in the natural moral inclinations of people, families and firms. Which policies prevent a widening gap between higher and lower educated people? Which policy instruments are there, and how could they be used? What is the role of free entrepreneurship?

Cities in Transition : Globalization, Political Change and Urban Development
This book was written with the aim of showing that even in the era of globalization developments appearing in cities are not subject to almost unconditional global forces. Rather, universal forces are decisive eventualities in the process of urban restructuring, often influencing its course and speed, yet developments and particularities within a city strongly influence the course of events and the extent to which negative characteristics of globalization might occur.

Chance : The life of games and the game of life
With its many easy-to-follow mathematical examples, this book takes the reader on an almost chronological trip through the fascinating and amazing laws of chance, omnipresent in the natural world and in our daily lives. Along the route many fascinating topics are discussed, such as: challenging probability paradoxes; "paranormal" coincidences; game odds; causes and effects; interpretation of opinion polls; winning chances as a game proceeds; the nature of randomness; entropy and randomness; randomness in life; algorithmic complexity and the undecidability of randomness; possibilities and limitations of learning the laws of a Universe immersed in chance events. This charming book will inform and entertain the scientist and non-scientist alike.
Catastrophic Events Caused by Cosmic Objects
Many times all of us could hear from mass media that an asteroid approached and swept past the Earth. Such an asteroid or comet will inevitably strike the planet some day. This volume considers hazards due to collisions with cosmic objects, particularly in light of recent investigations of impacts by the authors. Each chapter written by an expert contains an overview of an aspect and new findings in the field. The main hazardous effects – cratering, shock, aerial and seismic waves, fires, ejection of dust and soot, tsunami are described and numerically estimated. Numerical simulations of impacts and impact consequences have received much attention in the book. Fairly small impacting objects 50 -100 m in diameter pose a real threat to humanity and their influence on the atmosphere and ionosphere is emphasized.
Business Ethics : The Ethical Revolution of Minority Shareholders
The empirical part of the book presents four cases of US, French and Israeli companies, most of them in high-tech, in which the minority shareholders lose almost all of their investments. The cases are based on current events and try to find the common aspects and basic rules that govern the wrongdoing to minority shareholders.The book concludes that once the minority shareholders, who are ultimately all of us, are assisted by the new vehicles of Ethics, and are properly organized, motivated and conscious of their strengths, they will be able to win their fight and safeguard their interests.
Bioremediation of Soils Contaminated with Aromatic Compounds
Environmental biotechnology, which was in its infancy in the early 80's, has evolved thanks to the revolution brought about by molecular biology. Multiple successes in the biological cleanup of civil and industrial wastewater and of hydrocarbon soil pollution, demonstrate the vast power of clean technologies. In addition, the buildup of information on the activities of microorganisms as catalysts in all sorts of natural, industrial and animal environments has flourished. There is a continuing realization of the critical role of microbial processes in biological, industrial and geological systems. Since environmental biotechnology has matured, it is ready to tackle bigger challenges: the scaling up of many bioremediation systems still in progress, the search for novel biocatalysts for industrial applications, the continuing effort against common human life-threatening processes such as antibiotic resistance, the accumulation of hormone-mimicking substances (endocrine disrupters), the deposition of air-borne pesticides in the environment and, the degradation of recalcitrant contaminants. These endeavors will help prevent the contamination of food chains, protect human life and allow for human activity and economic development that do not compromise environmental sustainabijity.
Biophysical Aspects of Transmembrane Signaling
Transmembrane signaling is one of the most significant cell biological events in the life and death of cells in general and lymphocytes in particular. Until recently biochemists and biophysicists were not accustomed to thinking of these processes from the side of a high number of complex biochemical events and an equally high number of physical changes at molecular and cellular levels at the same time. Both types of researchers were convinced that their findings are the most decisive, having higher importance than the findings of the other scientist population. Both casts were wrong. Life, even at cellular level, has a number of interacting physical and biochemical mechanisms, which finally build up the creation of an "excited" cell that will respond to particular signals from the outer or inner world.
BioMEMS and biomedical nanotechnology ; Vol. III : Therapeutic Micro/Nanotechnology
The human body is composed of structures organized in a hierarchical fashion: from biomolecules assembled into polymers, to multimeric assemblies such as cellular or-ganelles, to individual cells, to tissues, to organ systems working together in health and disease- each dominated by a characteristic length scale. Decades of science and engineer-ing are now converging to provide tools that enable the orderly manipulation of biological systems at previously inaccessible, though critically important, length scales (<100 mi-crons). Thus, the approaches described in this volume provide a snapshot of how micro-and nanotechnologies can enable the investigation, prevention, and treatment of human disease.The volume is divided into three parts. The first part, Cell-based therapeutics; cov- ers the merger of cells with micro- and anosystems for applications in regenerative medicine spanning the development of novel nanobiomaterials.
Biological processes associated with impact events
The biological effects of asteroid and comet impacts have been widely viewed as primarily destructive. The role of an impactor in the K/T boundary extinctions has had a particularly important influence on thinking concerning the role of impacts in ecological and biological changes. th During the 10 and final workshop of the ESF IMPACT program during March 2003, we sought to investigate the wider aspects of the involvement of impact events in biological processes, including the beneficial role of these events from the prebiotic through to the ecosystem level. The ESF IMPACT programme (1998-2003) was an interdisciplinary effort that is aimed at understanding impact processes and their effects on the Earth environment, including environmental, geological and biological changes.
Beyond Kyoto : A new global climate certificate system : Continuing Kyoto commitsments or a global ´Cap and Trade´ scheme for a sustainable climate policy?
This book shows how humankind can ‘prevent dangerous interference with the c- mate system’ without dangerous interference with the global economic system. In the two underlying studies on behalf of the Ministry of Environment and Transport of i the German federal state of Baden-Württemberg, the results have been elaborated through scientific evaluation of different climate protection systems and intensive developmental work on an efficient climate protection system. The results will be presented in nine chapters according to the following nine basic R&D steps: 1. Quantifying the ‘ultimate climate objective’ of the world community in order ‘to prevent dangerous interference with the climate system,’ thus achieving climate sustainability; 2. Development of a comprehensive standard system for evaluating the prospect of success for different climate protection systems; 3. Based on this scientific standard system, evaluation of the current Kyoto system and of the most important proposals for ‘incremental regime evolution’ of the Kyoto system. Unfortunately, it must be noted that these systems are incapable of achi- ing climate sustainability; 4. Evaluating three proposals for ‘structural regime change’ of the Kyoto system. Following this objective evaluation process and numeric comparison of the diff- ent proposals, 5. Description of the eight basic elements of GCCS and its in-depth ‘critical asse- ment;’ 6.
Average-Cost Control of Stochastic Manufacturing Systems
This book is concerned with hierarchical control of manufacturing systems under uncertainty. It focuses on system performance measured in long-run average cost criteria, exploring the relationship between control problems with a discounted cost and that with a long-run average cost in connection with hierarchical control. A new theory is articulated that shows that hierarchical decision making in the context of a goal-seeking manufacturing system can lead to a near optimization of its objective. The approach in the book considers manufacturing systems in which events occur at different time scales.
Automatic Autocorrelation and Spectral Analysis
It takes advantage of greater computing power and robust algorithms to produce enough candidate models to be sure of providing a suitable candidate for given data. Improved order selection quality guarantees that one of the best (and often the best) will be selected automatically. The data themselves suggest their best representation. Should the analyst wish to intervene, alternatives can be provided. Written for graduate signal processing students and for researchers and engineers using time series analysis for practical applications ranging from breakdown prevention in heavy machinery to measuring lung noise for medical diagnosis.
Astrophysical concepts
This classic text, aimed at senior undergraduates and beginning graduate students in physics and astronomy, presents a wide range of astrophysical concepts in sufficient depth to give the reader a quantitative understanding of the subject. Emphasizing physical concepts, the book outlines cosmic events but does not portray them in detail: it provides a series of astrophysical sketches. For this fourth edition, nearly every part of the text has been reconsidered and rewritten, new sections have been added to cover recent developments, and others have been extensively revised and brought up to date. The book begins with an outline of the scope of modern astrophysics and enumerates some of the outstanding problems faced in the field today. The basic physics needed to tackle these questions are developed in the next few chapters using specific astronomical processes as examples. The second half of the book enlarges on these topics and shows how we can obtain quantitative insight into the structure and evolution of stars, the dynamics of cosmic gases, the large-scale behavior of the Universe, and the origins of life.
