"Cada escritura nace de un deseo, de una pasión ..., los libros, que parecen objetos inanimados, ocultan mucho más que ideas". Comparto estas palabras de Tiziana Plebani, su libro, sin duda, es fruto del deseo de aunar la historia erudita del libro con la atención a lo particular, a lo cotidiano, y con la voluntad de dar espacio a los cuerpos de las mujeres y de los hombres en la historia de lo escrito en la Europa Mediterránea, especialmente en Italia, y es un deseo hecho realidad

The amorphous silica (opal-A) speleothems associated to the open structural system of granitic rocks where the slow circulation of runoff is produced are mainly the result of the biological degradation of the rock. These speleothems are found in many different geographic, climatic and geological environments though always associated to granitoids. They show two different morphologies: cylindrical or long bodies and laminar or layered forms. They are internally formed by a mass of clasts and spheres of opal-Awith a porous texture that evolves to compact and massive due to the reiteration of the re-dissolution/re-precipitation of the amorphous opal by the water that circulates through it after each rainfall period. A final characteristic of each growth stage (end of rainy period) is the development of whiskers of minerals, normally gypsum, on the water output points of the speleothems. The dimensions of the speleothems are millimetric (length and/or thickness). In this paper their morphology and mineralogy are described based on their study by SEM, XRD and XRF, and there is established a new and more complete genetic hypothesis than the one that exists up to now to understand their formation

La coordinación de recursos en situaciones de emergencia requiere de procedimientos y herramientas que faciliten a los distintos cuerpos operativos el acceso a la información necesaria en el menor tiempo posible para tomar mejores decisiones. Los sistemas de información geográfica de código abierto y los estándares destinados a la difusión de información geográfica se encuentran en un estado de madurez tal que permiten dar respuesta a esta este escenario, facilitando la construcción de soluciones tecnológicas adecuadas para la prevención, gestión y seguimiento de este tipo de situaciones de emergencia. Este artículo trata de compartir la experiencia en el desarrollo de un sistema de información geográfica de apoyo a la gestión de emergencias ingredado en una solución vertical de extendido uso en el ámbito nacional. Para ello, se expondrán las claves tecnológicas y funcionales del SIG, haciendo especial hincapié en las ventajas que proporciona el empleo de estándares abiertos en el intercambio y explotación de información en un contexto tan exigente

The Guilleries are a small and mountainous area located in the north-westem part of the Catalonian Coastal Ranges where metamorphic and igneous Paleozoic rocks are exposed. After the main hercynian folding this area was affected by a brittle deformation that is mainly manifested by the intrusion of a very large number of dykes of granodiorite and the development of a complex joint system. Trends of dykes indicate that their intrusion was related to a SE-NW extension, whose estimated value is 40% on an average. This extension seems to stand, although without any associated igneous event, with the development of NE-SW directed joints which make the main set. Five families more were developed later, one gently-dipping and fou upright; the latter trending roughly SE-NW, ENE-WSW, ESE-WNW and N-S. AU the joint sets appear in the metasedimentary Paleozoic rocks and in the hercynian intrusive bodies. Concerning the ages, joints that belong to the NE-SW and SE-NW directed sets and also those slightly dipping have been attributed to the late-hercynian times and all the other are considered to be later
