Abstract

Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. The ecological and environmental aspects of non-native invasive plants are of great importance to (i) understand ecological principles involved in the management of invasives, (ii) design management strategies, (iii) find effective management solutions for some of the worst invaders, and (iv) frame policies and regulations. The objectives of this book are to discuss (i) ecological approaches needed to design effective management strategies, (ii) recent progress in management methods and tools, (iii) success and failure of management efforts for some of the worst invaders, and (iv) restoration and conservation of invaded land. In an effort to achieve these objectives, contributing authors have strived to provide up-to-date information on the management of non-native invasives. Chapters included in the book are peer-reviewed by international experts working in the area. Readers will get a unique perspective on ecological aspects of the management of invasives. The book will be useful to graduate students, researchers, managers and policy makers involved in the management of exotic invasives.

Abstract

Many cooling systems use water as cooling medium. They are found in public buildings, industrial production systems or power plants. Almost every cooling system using water is degraded by deposition, corrosion and microbiological fouling. This book identifies the whole bunch of problems due to water cooling systems and proposes specific solutions to all of them. The authors have an expertise of over 20 years solving cooling water problems. In this book, they advise all practitioners which need to plan, buy or operate cooling systems.

Abstract

The study of plant invasions is the science that attempts to understand causes and consequences of plant introductions outside of their native areas. Invasive plants have an impact on global biodiversity and ecosystem function, and their management is a complex and formidable task. The applied aspects of this study include the health and economic impacts of invasions. Although research on plant invasions has progressed remarkably during the past several decades, scientists are still looking for answers to basic questions. Such questions are: (1) What are invaders? (2) Can we predict invaders? (3) What are mechanisms of exclusion of native species by invaders? (4) How general principles in ecology can be used to predict and understand plant invasions? (5) What makes a habitat susceptible to invasion? (6) What agricultural practices influence invasion? (7) What impact invaders may have on ecosystem processes and community structure? (8) What are causes, mechanisms and consequences of plant invasions (9) What are the environmental and economic costs of invasion? (10) What management strategies are needed to check invasion? In an effort to answer these questions, contributing authors have strived to provide up-to-date reviews and discussions of invasion-related research involving natural and agroecosystems. Readers will get a unique perspective on ecological and agricultural aspects of plant invasions through employing general principles of ecology to plant invasions.

Abstract

Algèbre commutative, Chapitres 5 à 7 Les Éléments de mathématique de Nicolas BOURBAKI ont pour objet une présentation rigoureuse, systématique et sans prérequis des mathématiques depuis leurs fondements. Ce deuxième volume du Livre d'Algèbre commutative, septième Livre du traité, introduit deux notions fondamentales en algèbre commutative, celle d'entier algébrique et celle de valuation, qui ont de nombreuses applications en théorie des nombres et en géometrie algébrique. It traite également des anneaux de Krull ou de Dedekind. Il comprend les chapitres : Entiers ; Valuations ; Diviseurs. Il contient également des notes historiques. Ce volume est une réimpression de l'édition de 1965.

Abstract

Faire de l'Algèbre, c'est essentiellement calculer, c'est-à-dire effectuer, sur des éléments d'un ensemble, des (< opérations algébriques n, dont l'exemple le plus connu est fourni par les (< quatre règles )) de l'arithmétique élémentaire. Ce n'est pas ici le lieu de retracer le lent processus d'abstraction progressive par lequel la notion d'opération algébrique, d'abord restreinte aux entiers naturels et aux grandeurs mesurables, a peu à peu élargi son domaine, à mesure que se généralisait parallèlement la notion de (( nombre O, jusqu'à ce que, dépassant cette dernière, elle en vînt à s'appliquer à des éléments qui n'avaient plus aucun caractère (( numérique )>, par exemple aux permutations d'un - semble (voir Note historique de chap. 1). C'est sans doute la possibilité de ces extensions successives, dans lesquelles la forme des calculs restait la même, alors que la nature des êtres mathématiques soumis à ces calculs variait considérab- ment, qui a permis de dégager peu à peu le principe directeur des mat- matiques modernes, à savoir que les êtres mathématiques, en eux-mêmes, - portent peu: ce qui compte, ce sont leurs relations (voir Livre 1). Il est certain, en tout cas, que l'Algèbre a atteint ce niveau d'abstraction bien avant les autres parties de la Mathématique, et il y a longtemps déjà qu'on s'est accoutumé à la considérer comme l'étude des opérations algébriques, indépendamment des êtres mathématiques auxquels elles sont susceptibles de s'appliquer.

Abstract

This book is the fruition of work from contributors to the Art and Cartography: Cartography and Art symposium held in Vienna in February 2008. This meeting brought together cartographers who were interested in the design and aesthetics elements of cartography and artists who use maps as the basis for their art or who incorporate place and space in their expressions. The outcome of bringing together these like minds culminated in a wonderful event, spanning three evenings and two days in the Austrian capital. Papers, exhi- tions and installations provided a forum for appreciating the endeavors of artists and cartographers and their representations of geography. As well as indulging in an expansive and expressive occasion attendees were able to re? ect on their own work and discuss similar elements in each other's work. It also allowed cartographers and artists to discuss the potential for collaboration in future research and development. To recognise the signi? cance of this event, paper authors were invited to further develop their work and contribute chapters to this book. We believe that this book marks both a signi? cant occasion in Vienna and a starting point for future collabo- tive efforts between artists and cartographers. The editors would like to acknowledge the work of Manuela Schmidt and Felix Ortag, who undertook the task of the design and layout of the chapters.
