Aquest llibre recull una gran varietat d'experiències de govern territorial a Espanya. Una xarxa de quaranta-cinc investigadors procedents de catorze universitats espanyoles analitza exemples de bones i males pràctiques en relació amb el govern del territori. El predomini de les segones evidencia fins a quin punt roman inèdita a Espanya l'agenda de noves formes de govern democràtic i fins a quin punt prevalen la fragmentació i les visions tradicionals de governs gerencials, amb la complexitat afegida que ofereix el fet de tractar-se d'un Estat compost i, en conseqüència, molt complex, ...

The rapid growth of the discipline of aquatic ecology has been driven both by scientific interest in the complexities of aquatic ecosystems and by their enormous environmental importance and sensitivity. This book focuses on the remarkably diverse roles played by underwater plants, and is divided into three parts: 10 thematic chapters, followed by 18 case studies, and rounded off by three integrative chapters. The topics range from macrophytes as fish food to macrophytes as mollusc and microbe habitat, making this of interest to aquatic ecologists as well as limnologists, ecosystem...

El estudiante de bachillerato es un principiante en Física y no se le puede pedir que improvise en la resolución de problemas. Este libro proporciona una buena selección de problemas cubriendo, prácticamente, lo que se ve durante el curso, utilizando de vez en cuando, problemas propuestos en el examen final de bachillerato.

In previous volumes in this series, Advances in Metal and Semiconductor Clusters, the focus has been on atomic clusters of metals, semiconductors and carbon. Fundamental gas phase studies have been surveyed, and most recently scientists have explored new materials which can be produced from clusters or cluster precursors. In this latest volume, the focus shifts to clusters composed primarily of non-metal molecules or atoms which have one or more metal atoms seeded into the cluster as an impurity. These clusters provide model systems for metal ion solvation processes and metal-ligand...
