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...

Bolivia has one of the most diverse floras in South America.The grass family has exploited all of the diverse habitats of Bolivia, with the result that 740 species are recorded for the country. Descriptions and keys to aid identification are provided for the genera and species and illustrations of over 80% of the taxa are included.

Más de 30 mil científicos han firmado una declaración en la que afirman que no hay evidencia científica que apoye la idea de un calentamiento global provocado por el hombre. Sin embargo, alertas catastróficas auguran un futuro próximo aterrador si no dejamos de producir el dióxido de carbono que, se supone, causa el aumento de las temperaturas en todo el mundo. ¿Pero es esto realmente cierto? Diversas investigaciones demuestran lo contrario. ¿Por qué entonces la agenda sobre el calentamiento global se ha impuesto con tanta fuerza? Miles de millones de dólares están en juego, tanto ...

Conceptual Physics, Tenth Edition helps readers connect physics to their everyday experiences and the world around them with additional help on solving more mathematical problems. Hewitt's text is famous for engaging readers with analogies and imagery from real-world situations that build a strong conceptual understanding of physical principles ranging from classical mechanics to modern physics. With this strong foundation, readers are better equipped to understand the equations and formulas of physics, and motivated to explore the thought-provoking exercises and fun projects in each chapter. ...
