Galaxies have a history. This has become clear from recent sky surveys which have shown that distant galaxies, formed early in the life of the Universe, differ from the nearby ones. New observational windows at ultraviolet, infrared and millimetric wavelengths (provided by ROSAT, IRAM, IUE, IRAS, ISO) have revealed that galaxies contain a wealth of components: very hot gas, atomic hydrogen, molecules, dust, dark matter ... A significant advance is expected due to new instruments (VLT, FIRST, XMM) which will allow one to explore the most distant Universe. Three Euroconferences have been...

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

A study covering the gas-phase chemistry of organometallic ions. Topics covered include: periodic trends in gas-phase thermochemistry of transition metal-ligand systems; ab initio calculations to determine electronic structure, geometric structure, and thermochemistry of metal-containing systems; electronic state effects on metal ion reactivity; organometallic ion photochemistry; and applications of gas-phase electron transfer equilibria in organometallic redox thermochemistry. Also included are state-of-the-art mass spectrometric instrumentation used in such studies. It also features a...

No es de extrañar que la Meteorología haya interesado desde siempre al ser humano, habida cuenta de su utilidad: de ella dependen las cosechas, la seguridad aérea o la posibilidad de rellenar incómodos silencios en el ascensor. Pero ¿cuánto sabemos en realidad sobre los caprichos del tiempo y el clima? ¿A qué se deben los anticiclones, las tormentas o los vendavales que nos anuncian, en ocasiones, los hombres del tiempo? ¿En qué basan sus predicciones? Teniendo en cuenta que hablamos del tiempo a todas horas, es paradójico lo poco y mal conocida que es la meteorología por parte...
