El envase de polietilentereftalato: su impacto medioambiental y los métodos para su reciclado

La era de Casandra cuestiona la actual moda ensayística de intentar reducir la complejidad de nuestra sociedad a algún principio abstracto y mal definido con el que se pretende explicar todas las facetas de nuestra vida, ya sea ofreciendo escenarios apocalípticos u optimismos ingenuos. Como alternativa, el texto propone una epistemología del no saber, de aceptar que no existen modelos que lo puedan explicar todo y resolver cada problema desde su contexto concreto y la incertidumbre inevitable. En un tono ameno y a veces irónico, se analizan así tendencias actuales como el neurocientismo ...

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...

progress and happiness - however these terms may be understood in detail - as a significant and constitutive element of scientific inquiry. In this sense the question of the way in which sport really benefits people and contributes to their happiness, and under which individual and social conditions, is a scientific question. It assumes special significance when the fact is taken into account that in the field of sport science a general scepticism is shown towards those dogmas and pedagogical theses which take such an interpretation for granted in the absence of a firm empirical foundation...
