Les missions Petersberg són l'operatiu militar més ambiciós organitzat per la Unió Europea en el desenvolupament de la CSDP, Política Europea de Seguretat i Defensa. Amb l'objectiu d'aconseguir una organització efectiva y funcional d'aquestes missions, és desitjable que les cultures estratègiques dels diferents Estats membres siguin, en gran mesura, compatibles en benefici d'una cultura estratègica europea amb directrius clares. Aquest estudi compara les cultures estratègiques d'Alemanya, el Regne Unit i França en referència al seu nivell de compatibilitat contrastant-les amb dos casos recents, exemples paradigmàtics de cultures estratègiques integrals. D'aquesta manera, pretenem descriure les circumstàncies en què es desenvolupen les missions Petersberg.

Este trabajo final de máster se centra en describir la realidad que afecta al periodismo de filtración. Además se analiza detalladamente el caso Planning Tool for Resource Integration, Synchronization, and Management (PRISM). Se ha averiguado qué han hecho los medios con ésta información, identificado cada elemento clave de esta trama, descrito la situación mediática actual y se han expuesto las repercusiones que ha tenido esta noticia a nivel internacional y a nivel personal. Se analizan además las noticias, artículos o ensayos que se han escrito sobre el tema para averiguar qué se ha conseguido con éste filtraje y finalmente, se han observado las consecuencias de tal acto.

El objetivo de este estudio se centró en analizar una colección privada de germoplasma de Vitis vinifera L., de 338 cultivares procedentes de 24 países, para caracterizarlas creando una base de datos, utilizando 11 marcadores microsatélites o SSR (Simple Sequence Repeat). Como resultado se encontraron que algunas de las muestras analizadas presentaron un perfil idéntico de SSR, indicando que se trata de una sinonimia (la misma variedad pero con diferente nombre). Se detectaron 293 perfiles únicos. Adicionalmente, 15 pares de variedades presentaron diferencias en un solo locus y otros 7 grupos difieren en 2 loci, lo cual indicaría la alta proximidad genética entre esas variedades, sin llegar a ser la misma. El germoplasma analizado cuenta con una compleja biodiversidad varietal que se debe preservar. El estudio se realizó programando para el primer año la revisión bibliográfica detallada, recolección de las hojas y el inicio de la puesta a punto de la metodología, en el segundo año se completa la puesta a punto de la metodología, se trituran las hojas y se realiza la extraccinón del ADN. El tercer año se emplea para amplificar los fragmentos de ADN por medio de la PCR (reacción en cadena de la polimerasa), obtener la longitud de los fragmentos con un secuenciador ABI PRISM 310, valorar resultados y realizar repeticiones. El último año se analizan los resultados obtenidos, se realizan repeticiones pertinentes y se comienza la redacción de artículos científicos.

The role of public health has been a central topic on the classical debate about the historical mortality decline in Europe. One of these health initiatives were the Milk Depots. Spain set up those centres from the late 19th century until the beginning of the Civil War. The goal of this paper is to evaluate the effect of this health intervention on the infant mortality decline during this period. This study works out three kinds of sources: Statistical Yearbooks, Official documents and local records produced by the same Milk Depot. It analyses data available for all the country and one local case such as the Barcelona’s Milk Depot (1904-1935). The main methodological issue deals with the measurement of the effect of the Milk Depot activities on the pattern of changes of infant mortality. Results suggest that Milk Depots have a positive but quite moderate effect on the improving of overall levels of child survival.

We present computer simulations of a simple bead-spring model for polymer melts with intramolecular barriers. By systematically tuning the strength of the barriers, we investigate their role on the glass transition. Dynamic observables are analyzed within the framework of the mode coupling theory (MCT). Critical nonergodicity parameters, critical temperatures, and dynamic exponents are obtained from consistent fits of simulation data to MCT asymptotic laws. The so-obtained MCT λ-exponent increases from standard values for fully flexible chains to values close to the upper limit for stiff chains. In analogy with systems exhibiting higher-order MCT transitions, we suggest that the observed large λ-values arise form the interplay between two distinct mechanisms for dynamic arrest: general packing effects and polymer-specific intramolecular barriers. We compare simulation results with numerical solutions of the MCT equations for polymer systems, within the polymer reference interaction site model (PRISM) for static correlations. We verify that the approximations introduced by the PRISM are fulfilled by simulations, with the same quality for all the range of investigated barrier strength. The numerical solutions reproduce the qualitative trends of simulations for the dependence of the nonergodicity parameters and critical temperatures on the barrier strength. In particular, the increase in the barrier strength at fixed density increases the localization length and the critical temperature. However the qualitative agreement between theory and simulation breaks in the limit of stiff chains. We discuss the possible origin of this feature.

Three-dimensional reconstruction of reservoir analogues can be improved combining data from different geophysical methods. Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) data are valuable tools, since they provide subsurface information from internal architecture and facies distribution of sedimentary rock bodies, enabling the upgrading of depositional models and heterogeneity reconstruction. The Lower Eocene Roda Sandstone is a well-known deltaic complex widely studied as a reservoir analogue that displays a series of sandstone wedges with a general NE to SW progradational trend. To provide a better understanding of internal heterogeneity of a 10m-thick progradational delta-front sandstone unit, 3D GPR data were acquired. In addition, common midpoints (CMP) to measure the sandstone subsoil velocity, test profiles with different frequency antennas (25, 50 and 100MHz) and topographic data for subsequent correction in the geophysical data were also obtained. Three ERT profiles were also acquired to further constrain GPR analysis. These geophysical results illustrate the geometry of reservoir analogue heterogeneities both depositional and diagenetic in nature, improving and complementing previous outcrop-derived data. GPR interpretation using radar stratigraphy principles and attributes analysis provided: 1)tridimensional geometry of major stratigraphic surfaces that define four units in the GPR Prism, 2) image the internal architecture of the units and their statistical study of azimuth and dips, useful for a quick determination of paleocurrent directions. These results were used to define the depositional architecture of the progradational sandbody that shows an arrangement in very-high-frequency sequences characterized by clockwise paleocurrent variations and decrease of the sedimentary flow, similar to those observed at a greater scale in the same system. This high-frequency sequential arrangement has been attributed to the autocyclic dynamics of a supply-dominated delta- front where fluvial and tidal currents are in competition. The resistivity models enhanced the viewing of reservoir quality associated with cement distribution caused by depositional and early diagenetic processes related to the development of transgressive and regressive systems tracts in igh-frequency sequences.

A set of GPR profiles have been recorded in order to determine the 3D geometry of a prograding delta-front sandbody (Roda sandstone formation, Eocene, Graus-Tremp basin). Common Mid Points (CMP) also have been recorded to obtain the velocity of the electromagnetic wave in ground. In order to build the topsurface of a 3D prism a set of topographic points have been acquired. Most of the GPR profiles are oriented parallel to the progradation direction (NNE-SSW) and show the expected geometries. The 3D prism has been built from the individual profiles, which shows the three dimensional geometry of the sandy lithosome.

The paper discusses the problem of the literary genre of the Crónica sarracina from a peninsular and european points of view. It is considerer through the prism of a new kind of fiction, related to history and an incipient realism, which grows up along the 15th century. Moreover, it reveals new fragments inspired by Pedro de Corral from the catalan version of Seneca’s tragedies and from the Libro de los doce sabios
