Buch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This monograph is the rst systematic presentation of the theoretical fun- mentals of the physics of porous structures and it is intended for basic fa- liarization with the subject. That is why we tried to avoid, where possible, excessive mathematics and to pay as much attention to the visual presen- tion of the general physical picture of various phenomena as possible. Even in those cases where there is an accurate mathematical theory we avoid ri- rous mathematical proofs, assuming that the reader is acquainted with the fundamentals of quantum mechanics and statistical physics and in particular cases will be able to reproduce the calculations of interest. For a more detailed and sound study of particular problems the reader may refer to the original papers and monographs listed at the end of the book. The book includes ve chapters. The rst chapter deals with the model of porous medium based on the notion of the bril structure of substance which allows us theoretically analyze some seemingly ¿desperate¿ problems. Moreover, included in this chapter is some information from the thermo- namics of equilibrium systems. The second chapter deals with a number of issues connected with the investigation of purely equilibrium characteristics of such structures, including heat capacity and mechanical strength. Ch- ter 4 concerns the physical bases of fast processes in porous media. Chapter 5 shows the development of a consistent theory of heat conduction in porous substances.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 280 pp. Englisch. …

Neuware -The United Nations Conference on the Environment and Development (UNCED), held in Rio de Janeiro in 1992, spawned a multitude of pro grammes aimed at assessing, managing and conserving the earth's biological diversity. One important issue addressed at the conference was the mountain environment. A specific feature of high mountains is the so-called alpine zone, i. e. the treeless regions at the uppermost reaches. Though covering only a very small proportion of the land surface, the alpine zone contains a rela tively large number of plants, animals, fungi and microbes which are specifi cally adapted to cold environments. This zone contributes fundamentally to the planet's biodiversity and provides many resources for mountain dwelling as well as lowland people. However, rapid and largely man-made changes are affecting mountain ecosystems, such as soil erosion, losses of habitat and genetic diversity, and climate change, all of which have to be addressed. As stated in the European Community Biodiversity Strategy, 'the global scale of biodiversity reduction or losses and the interdependence of different species and ecosystems across national borders demands concerted international action'. Managing biodiversity in a rational and sustainable way needs basic knowledge on its qualitative and quantitative aspects at local, regional and global scales. This is particularly true for mountains, which are distributed throughout the world and are indeed hot spots of biodiversity in absolute terms as well as relative to the surrounding lowlands.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 512 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Das Buch ist eine Einführung in die Programmiersprache Java. In den ersten Kapiteln werden die Grundlagen behandelt: Klassen, Objekte, Interfaces und Pakete. Weitere Kapitel befassen sich mit Benutzeroberflächen, der Ausnahmebehandlung, der Threadprogrammierung, Javas Sicherheitsmechanismen und dem Aufruf entfernter Methoden. Alle Sprachkonstrukte und die verwendeten Klassen der Java-Standardbibliothek werden an Beispielen verdeutlicht. An die einzelnen Kapitel schließt sich eine Reihe von Übungsaufgaben an. Die kompletten Beispielprogramme und Lösungen zu den Übungen befinden sich auf der beiliegenden CD-ROM.In der 4. Auflage wurde die Behandlung des IO-Frameworks um das New IO API (NIO), das seit JDK 1.4 neben das streambasierte API tritt, erweitert. Einige Client/Server-Beispiele wurden auf NIO umgestellt. Bei der Ausnahmebehandlung wurde das neue Java-Sprachkonstrukt der Zusicherungen (assertions) ergänzt.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 656 pp. Deutsch.…
