En este Minilibro se presenta deliberadamente una amplia cobertura de temas de modo que el estudiante adquiera una idea de cómo enfocar los diferentes tipos de problemas. Debemos advertir también al estudiante que el material del texto aqui presentado esta bastante condensado y, por tanto, seria una buena idea utilizar este libro junto con un texto estandar sobre el tema. Contiene las partes del Omnilibro que creemos que son aconsejables para un primer curso de reactores. Se puede considerar tambien este libro como la base de un curso autodidacta sobre el tema.

The island of Britain has over 10,000 miles of coastline, steeped in history and constantly shifting, changing, adapting and providing. The Restless Coast is a moving and beautiful account of a journey around it, during which the author travels its length to discover its challenges and opportunities, and to talk to the people trying to protect it. At once delightful travelogue and passionate defence, The Restless Coast shines a powerful spotlight into the thin line that surrounds us, and defines our status as islanders. Overarching the journey is the extraordinary natural history of the coastline, together with the story of how man has imprinted himself on its very geology and shape for countless centuries. Into the account, Roger Morgan-Grenville threads the modern challenges that the shoreline faces, and the people who are trying to protect it. At once informative, angry and funny, The Restless Coast is a very personal love letter to our island edge.

Mit Android und Arduino treffen die zwei Platzhirsche in ihrem jeweiligen Segment aufeinander. Android ist in den letzten Jahren zur Nummer eins unter den Smartphone-Betriebssystemen aufgestiegen. Arduino zahlt zu den wichtigsten Plattformen fur eigene Hardwareprojekte und wird weit uber die Elektronik hinaus eingesetzt, z. B. auch von Kunstlern. Android und Arduino haben eines gemeinsam: beide sind Open Source. Aufgrund dieser Eigenschaft haben sich hinter beiden Systemen riesige Communitys gebildet. Eine Kombination der beiden Systeme ist deswegen die perfekte Symbiose.Mit Android und Arduino treffen die zwei Platzhirsche in ihrem jeweiligen Segment aufeinander. Android ist in den letzten Jahren zur Nummer eins unter den Smartphone-Betriebssystemen aufgestiegen. Arduino zahlt zu den wichtigsten Plattformen fur eigene Hardwareprojekte und wird weit uber die Elektronik hinaus eingesetzt, z. B. auch von Kunstlern. Android und Arduino haben eines gemeinsam: beide sind Open Source. Aufgrund dieser Eigenschaft haben sich hinter beiden Systemen riesige Communitys gebildet. Eine Kombination der beiden Systeme ist deswegen die perfekte Symbiose. Bei Android handelt es sich um ein Betriebssystem auf der Basis von Linux. Nach einer Vorstellung der wichtigsten Eigenheiten von Android wird die Installation der Entwicklungsumgebung (IDE) erlautert. Als IDE kommt dabei Eclipse zum Einsatz. Anhand einer ersten Android-App wird schrittweise die Nutzung der IDE gezeigt. Praxis-Tipps fur Eclipse erleichtern den Umgang mit der IDE im Alltag. Mit vier Projektbeispielen, z. B. der Ansteuerung eines Servomotors, wird die Verbindung zwischen Android und Arduino Due anhand von Quellcode ausfuhrlich aufgezeigt. Der Quellcode dieser Projekte ist naturlich als Download-Material verfugbar.

En la publicación del Quinto Informe de Evaluación del Panel Intergubernamental del Cambio Climático (ipcc, por sus siglas en inglés), el documento más exhaustivo sobre el tema hasta la fecha, está claramente establecida la influencia humana en el clima y los efectos negativos que tienen nuestras actividades en el cambio climatico. Los efectos negativos se traducen en el aumento de la temperatura de la atmosfera, en la acidificacion de los oceanos, en los cambios en el ciclo global del agua, en el deshielo de los glaciares y en una frecuencia mayor de eventos climaticos extremos.Se sabe que los paises en vias de desarrollo no son los mas responsables del cambio climatico, pero si son los mas sensibles a sus efectos por varios motivos. Sus economias dependen mucho de sectores vulnerables al clima tales como la agricultura, la forestaria y la energia hidroelectrica; ademas, por razones economicas, son menos capaces de hacer frente a los impactos de unas condiciones climaticas extremas. Por lo tanto, hoy se publican muchos reportes y estudios sobre el cambio climatico en paises en vias de desarrollo.

An original, wide-ranging and carefully researched book ... contains important lessons for humanity. Mark Cocker, The SpectatorA fascinating insight into climate change biology around the globe, as well as in our own backyards.Hurricane Lizards and Plastic Squid is the first major book by a biologist to focus on the fascinating story of how the natural world is adjusting, adapting, and sometimes measurably evolving in response to climate change. Lyrical and thought-provoking, this book broadens the climate focus from humans to the wider lattice of life.Bestselling nature writer Thor Hanson - author of Buzz (a Radio 4 Book of the Week) - shows us how Caribbean lizards have grown larger toe pads to grip trees more tightly during frequent hurricanes; and how the plasticity of squid has allowed them to change their body size and breeding habits to cope with altered sea temperatures.Plants and animals have a great deal to teach us about the nature of what comes next, because for many of them, and also for many of us, that world is already here.
