Las plantas y sus usos en las islas de Providencia y Santa Catalina

This volume presents the proceedings of a 1986 Advanced Study Institute entitled "Structure/Reactivity and Thermochemistry of Ions", held at Les Arcs, France, June 30 to July 11, 1986. The format of a NATO Institute is ideally suited to in-depth communications between scien tists of diverse backgrounds. Particularly in the field of ion physics and chemistry, where on-going research involves physicists, physical chemists, and organic chemists - who use a variety of experimental and theoretical techniques - it is found that in the relaxed but stimula ting atmosphere of a NATO ASI, each...

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...

Biographies and bibliographies of members are included in many of the volumes. Lists of members are usually given on covers of the numbers.

La autora, tras más de quince años viajando a los países que conforman el Sahara y su periferia, ha terminado por vincularse emocionalmente, de manera intensa, con el mosaico de paisajes y culturas que habitan estos territorios. Sus viajes han sido al modo antiguo, el único que realmente permite ver más allá de la postal que resume los tópicos. Ella y sus compañeros han llegado a donde no llega el turista convencional; han vivido bajo el mismo techo y han compartido té y alimentos con familias tuareg, bereber o bororo; asistido a sus ceremonias y rituales; oído sus leyendas;...
