Perspectivas de investigación sobre los mamíferos silvestres de Guatemala

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...

Este manual clarifica al alumno de Física los conceptos adquiridos en sus estudios teóricos, y ayuda en el autoaprendizaje de la resolución de problemas de todos los aspectos de la Física de primeros cursos universitarios.Contiene mas de 2100 problemas totalmente resueltos y explicados, ordenados de acuerdo con los apartados del libro Física General de los mismos autores, tambien publicado por Editorial Tébar.

Numerosos cientficos de todo el mundo proponen ahora una reforestacin de grandes extensiones. La primera parte del libro est dedicada a la semilla como principal recurso de reforestacin, conservacin del germoplasma vegetal y recuperacin de especies valiosas. La segunda se trata de cmo promover el crecimiento de nuevos individuos (plantas) mediante el uso de tejidos vegetales.

The findings reported in this book on the methods of cluster measurements will lead to new avenues using nondestructive mass spectrometry and dipole mass isomers. Much attention is given to the physics and chemistry of fullerenes and nanotubes, including the problems surrounding the formation and growth of nanotubes, electron characteristics of fullerenes, the influence of solvents, simulation of the properties of carbon clusters, etc. Some unique experimental data on the conversion of aerosols into aerogels with the formation of fractal structures is provided. In addition, the book covers...
