PRESENCIA – OVNIs, Circulos en los Cultivos y Exocivilisaciones

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...

Estudi que analitza quines respostes s'estan donant des de les diferents administracions del territori per afrontar velles dinàmiques territorials crítiques com el despoblament rural, la dispersió i explosió urbana, la crisi industrial i del sector primari, l'esgotament del recurs aigua, la depredació del litoral i la pèrdua de paisatges, entre d'altres a unes àrees d'estudi que es poden considerar com a representatives de tots els tipus de territoris que podem trobar hui en dia l'Arc Mediterrani. s'abasta un àmbit tan heterogeni com és el litoral que recorre Catalunya, País...

Este libro nace de las inquietudes que nos generan las inequidades y desigualdades de género en diversas esferas, y particularmente en aquellas que enfrentamos diariamente como investigadoras y docentes. Las lecturas académicas, los resultados de nuestras investigaciones y las experiencias cotidianas alimentaron nuestro interés por comprender las motivaciones, los obstáculos y las barreras que enfrentan las mujeres que se deciden por la vida académica. La literatura que ha abordado esta problemática expone que las causas del éxito o fracaso en la vinculación y posterior permanencia de ...

Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore -- there are huge yawning voids in our basic notions of how the world works. Jorge Cham and Daniel Whiteson team up to explore everything we don't know about the universe, and while introducing the biggest mysteries in physics, they also helpfully demystify many complicated things we do know. And although the universe is full of weird things that don't make any sense, Cham and Whiteson make a case that the questions we can't answer are as interesting as the ones we can, and they invite...
