THE LAND OF THE WHITE BIRDS presents a chance for children aged 6-12 and their parents to increase their environmental awareness together. It is a book for reading on your own as well as for reading aloud. The book contains a section with a varied range of activities, based on the super learning system, that help to deepen the children's knowledge about processes of cause and effect in our natural environment. Young readers are captivated following the adventures of Nick, a young hare who lives in the country, and Croak, a city-dwelling raven. The two face a series of challenges that threaten to endanger and destroy their habitat, nature around them and indeed our whole planet. But there is also Mull, a wise mole. He can see into the future and he knows that the efforts many people make to create a worthwhile future won't be in vain. Also, Mull knows that it is children in particular - the "little humans", as he calls them - who can help the plants, the animals and the whole earth to have a better life.
For most areas of medical ultrasound, textbooks that provide physicians with detailed, practical information are readily available. Unfortunately, for the field of ultrasound mammography, such texts are few in number, in comparison to the num ber available for other fields of medical ultrasound. This textbook by Drs. Hack eHler, Duda, and Lauth fills this gap by presenting a clear overview of the usefulness and limitations of ultrasound mammography. Information based on clinical experiences with various types of automated and real-time instrumentation is presented in a manner that allows physicians to make their own judgments regarding the diagnostic capabilities of ultrasound mammogra phy. It also provides specific information on techniques required to obtain useful diagnostic data. Examples of the many possible image variations of specific breast pathologies are presented. The advantages of recent real-time systems, when used with a stand-off, are clearly outlined. The authors do not belabor the philosophical dilemma of which sys tem, an automated or a real-time, is best suited for ultrasound mammography. They simply present the information they have gained in their use of both of these systems and indicate that, in the future, a combination of automated and real-time would be the most valuable for the physician.
This second edition of a bestselling textbook offers an instructive and comprehensive overview of our current knowledge of biocatalysis and enzyme technology. The book now contains about 40% more printed content. Three chapters are completely new, while the others have been thoroughly updated, and a section with problems and solutions as well as new case studies have been added. Following an introduction to the history of enzyme applications, the text goes on to cover in depth enzyme mechanisms and kinetics, production, recovery, characterization and design by protein engineering. The authors treat a broad range of applications of soluble and immobilized biocatalysts, including wholecell systems, the use of non-aqueous reaction systems, applications in organic synthesis, bioreactor design and reaction engineering. Methods to estimate the sustainability, important internet resources and their evaluation, and legislation concerning the use of biocatalysts are also covered.
Individual mobility is one of the most important needs of modern society and an important link between private, public and economic life. In contrast, transport also entails severe environmental and social burdens, foiling current efforts for sustainable development. As the main source of CO2 emissions, transport is a prominent driver for climate change, and individual car traffic is responsible for nearly a third of the total energy consumption. However, we have to consider that many commuters feel indeed very dependent on their car. Here, ridesharing promises to contribute to environmental protection, while still offering individual mobility. Although ridesharing options have been discussed since many years, internet and smartphones provide completeley new opportunities to find ridesharing partners today. Thus, this book deals with current efforts on implementing flexible internet- and phone-based ridesharing services. With a main focus on the users‘ perspective, their demands and acceptance limits, we aim to explore success factors for non-profit, but also commercial ridesharing concepts.
This self-contained text/reference provides a basic foundation for practitioners, researchers, and students interested in any of the diverse areas of multiscale (geo)potential theory. New mathematical methods are developed enabling the gravitational potential of a planetary body to be modeled using a continuous flow of observations from land or satellite devices. Harmonic wavelets methods are introduced, as well as fast computational schemes and various numerical test examples. Presented are multiscale approaches for numerous geoscientific problems, including geoidal determination, magnetic field reconstruction, deformation analysis, and density variation modelling With exercises at the end of each chapter, the book may be used as a textbook for graduate-level courses in geomathematics, applied mathematics, and geophysics. The work is also an up-to-date reference text for geoscientists, applied mathematicians, and engineers.
This book introduces and explains how to conduct a Social Return on Investment (SROI) analysis. It discusses the various advantages and disadvantages of different research strategies and designs, and explores the different ways in which SROI analysis results can be used for communication, outreach, and strategic decision-making. It provides insights into how and to what extent SROI analyses can help to meet different expectations, and presents different social impact research designs and methods. It presents an analytical framework for the identification of a proper SROI analysis, and shows readers how to establish an impact model, introducing a stakeholder-based approach.
Individual-based models are an exciting and widely used new tool for ecology. These computational models allow scientists to explore the mechanisms through which population and ecosystem ecology arises from how individuals interact with each other and their environment. This book provides the first in-depth treatment of individual-based modeling and its use to develop theoretical understanding of how ecological systems work, an approach the authors call "individual-based ecology.? Grimm and Railsback start with a general primer on modeling: how to design models that are as simple as possible while still allowing specific problems to be solved, and how to move efficiently through a cycle of pattern-oriented model design, implementation, and analysis. Next, they address the problems of theory and conceptual framework for individual-based ecology: What is "theory"? That is, how do we develop reusable models of how system dynamics arise from characteristics of individuals? What conceptual framework do we use when the classical differential equation framework no longer applies? An extensive review illustrates the ecological problems that have been addressed with individual-based models. The authors then identify how the mechanics of building and using individual-based models differ from those of traditional science, and provide guidance on formulating, programming, and analyzing models. This book will be helpful to ecologists interested in modeling, and to other scientists interested in agent-based modeling.
The focus here is on density matrix theory cast into a representation - SU(n) algebra - since this is particularly adapted to describing networks of quasi-molecular subsystems. This approach allows an understanding of how classical properties emerge within a quantum mechanical world and how non-classical features survive in a classical environment. The authors introduce and discuss non-classical aspects such as single-particle and multi-particle coherence such that a picture evolves of how these features are generated and destroyed by interactions with the environment. The outcome is a description of how the dynamics of individual quantum systems are interrelated with information dynamics.
Large eddy simulation (LES) seeks to simulate the large structures of a turbulent flow. This is the first monograph which considers LES from a mathematical point of view. It concentrates on LES models for which mathematical and numerical analysis is already available and on related LES models. Most of the available analysis is given in detail, the implementation of the LES models into a finite element code is described, the efficient solution of the discrete systems is discussed and numerical studies with the considered LES models are presented.
Eine Übersicht für Architekten, die auch die Bedeutung der Baustoffwahl für die sinnliche Wahrnehmung von Architektur wie Haptik, Geruch, Farbe, Oberflächenstruktur berücksichtigt, gab es bisher nicht. Mit dem Baustoff Atlas wird diese Lücke nun geschlossen. Als ein auf die Interessen von Architekten und Bauingenieuren gleichermassen abgestimmtes Grundlagenwerk wird er alle genannten Betrachtungsebenen vereinen. Dabei werden sowohl grundsätzliche Nachhaltigkeitsfragen wie Lebensdauer, Umweltbelastung und Stoffkreisläufe erörtert als auch Materialinnovationen vorgestellt. Alle wesentlichen herkömmlichen und neuartigen Baustoffe werden hinsichtlich Herstellung, Verarbeitung, Oberflächen, Anschlüssen und Kenndaten umfassend dokumentiert. Internationale Beispiele, deren Erscheinungsbild sich häufig aus jeweils einem Material definiert, veranschaulichen die Anwendung in der Architektur. Der Baustoff Atlas unterstützt damit die tägliche Arbeit von Architekten und Ingenieuren bei der Baustoffauswahl auf eine umfassende, zugleich anschauliche und anregende Weise.
Dark matter has become one of the most exciting and central fields of astrophysics, particle physics and cosmology. The lectures and talks in these proceedings emphasize equally the experimental and theoretical perspectives of the ongoing search for dark matter in the universe, stressing in particular the interplay between astro- and particle physics.
Protection of the environment has nowadays become a major challenge and a condi tion for survival of future human generations and life on Earth in general. Yet it is still far too much of a dream or hope rather than a reality in the policy of our societies. Presently we are experiencing an unprecedented exponential growth of demography combined with a race for profit, resulting in excessive consumption particularly of en ergy, and a serious impact on the world ecosystems. Various types of pollutants and emerging new diseases not only disrupt the normal course of life, but also above this some of the atmospheric pollutants are most likely involved in the changing climate. We fear and literally shiver at the thought that the "changing climate" would ultimately disrupt the fragile thermodynamic equilibrium between the atmosphere and the oceans. Are we insensitive to these facts to the point of pushing our descendants, some genera tions ahead, into a new glacial period after a first period of warming up, at least, in northern Europe, like the one that took place 13 to 14 millennia ago? Surely the planet's nature is not prepared to be dominated by man and will go its way, whether humanity will be alive or dead.
The tradition of Suvretta meetings has always been to talk about failures and mistakes in order to learn for the future. This book, the result of the meeting in 2006, elaborates precise recommendations, to help the surgeon avoid mistakes and to treat recurrences after different types of non-mesh or mesh-repain in inguinal, incisional and hiatal hernia.
Text in English and German. The oeuvre of Stefan Wewerka occupies a unique position in post-war art because of the way in which he mixes different genres. Wewerka is an 'uomo universale', an uncomfortable pedagogue, a bringer of enlightenment. In addition to his practical work as an architect -- his competition entries have had a lasting effect on architectural discourse -- he has alienated architecture photographically or with the aid of traditional artistic techniques, has written books, has painted pictures, has made films and object art. In the early 50s Wewerka involved himself in earth architecture -- early attempts to build with nature and not against it -- and this at a time when no one was talking about ecology or even green building. Wewerka became known to a wider public in the 60s by the artistic allenation of chairs and other everyday objects, which he sawed up or distorted in order to undermine familiar images subversively. He also did not leave architectural 'high culture' untouched. Triumphal arches like the Arc de Triomphe in Paris or Gothic cathedrals heel over or buckle to form surreal structures and thus make their ideological claims questionable. In the late 70s Wewerka also started to design furniture which had high utility value despite its free form and which emanate an almost Bauhaus-like dignity. All this furniture, like the Fan Desk, the three-legged chair or the One-Swinger, and also his Kitchen Tree and the programmatic Cella furniture system stand like sculptures in the space and always derive a new and surprising variant from subjects and genres that seemed to be closed. The internationally known architecture and design historian Volker Fischer was vice director of the Deutsches Architekturmuseum in Frankfurt for over 10 years. For some time now he has been building up a new design department in the Museum fur Kunsthandwerk in Frankfurt; in addition to his museum work he teaches history of architecture and design at the Hochschule fur Gestaltung in Offenbach. Like Volker Fischer, architectural historian Andrea Gleiniger worked for many years in the Deutsches Architekturmuseum in Frankfurt; she now teaches at the Staatliche Hochschule fur Gestaltung in Karisruhe. Her principal working fields are the history of housing estates in the 20th century and the relationship between architecture, art and the new media.
