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...

Making knowledge about evolution available to everyone, this simple and entertaining book offers answers to the most frequently asked questions. Throughout the text, the reader is reminded of the importance of understanding evolutionary processes in order to approach present day human behavior, including social conduct, as well as the difficulty of trying to decipher the nature of modern human beings without going back to their zoological origin. Divided into two sections, the first one builds the foundation for the latter, which explains the evolution of life, beginning at the physical...

La condición juvenil contemporánea es posible pensarla desde su relación constitutiva con la acción colectiva. En esta relación hay una serie de elementos que son primordiales tales como la relacionalidad, el contexto socio-histórico en Latinoamérica (regido por la precariedad, el desencanto y la incertidumbre) y la comunicación, que se desarrolla en mediaciones, territorios y cuerpos. Sin embargo, además de dichos elementos centrales hay otras nociones y aproximaciones conceptuales que pueden aportar a la producción de conocimiento, desde el contexto latinoamericano, en torno a la...
