Resumen: The study of intraplate tectonics is crucial for understanding the deformation within plates, far from active plate
boundaries and associated stress transmission to the plate interiors. This paper examines the tectonic evolution
of the Variscan basement at the western margin of the Cenozoic Duero basin. Located east of the Vilariça
Fault
System in NW Iberia, this intraplate zone is a relatively flat but elevated area with an intense NNE-SSW
trending fault system and associated moderate seismicity. Although the area has played an important role in
the Duero basin configuration, its Alpine to present-day tectonic evolution has not been well constrained.
In order to characterize the successive paleostress fields, 1428 pairs of fault-striae were measured at 56 sites
and two focal mechanisms were used. Stress inversion methods have been applied to analyze paleostress
regimes. Results show the existence of three dominant maximum horizontal stress (Shmax) trends: N-S,
NE-SW and E-W. Relative and absolute dating of the activated faults for each Shmax shows that the clearly
predominant N-S paleostress field in the zone has been active since the Oligocene up to the present day; while
a NE-SW stress field is found to have been active during the Cretaceous and an older E-W paleostress field
was active in the earlier Alpine cycle (Late Triassic).
Resumen: The groundwater flow in zones of low permeability, as granites, is mainly associated with zones of fracture.
For this reason the characterization of the fractures is fundamental, both in surface as in depth, and must
integrate geological information (geological mapping, structural analysis), geophysics
(mainly electrical
and electromagnetic methods) and geochemistry (radon and others gases) with hydrogeology. In this work we analyze the geophysical response of a strike-slip fault zone by means of three 2D resistivity models. The objective is to investigate the presence of several conductive zones and their geometry in depth. The obtained results allow to control the geometry in depth of the fractures, the gaps between the different mapped traces along the fault zone as well as the thickness of landfill. All this information will be useful for the hidromechanical simulation of the massif, and to check the geometry and gas permeability calculated from emanometry.

Resumen: Fracture characterization in granites has been an important subject of study during these last years, by means of geological-structural cartography, hydrogeology and geochemical analysis. All these works have been carried out to investigate the hydromechanics and permeability in low-permeability rocks. In this study we apply
a surface geophysical method in order to characterize the permeability of the fault zones affecting “El Berrocal” granite (Central System, Spain). The low-induction electromagnetic method (EM) gives us the apparent resistivity values of the rocks at a maximum depth, allowing us to differentiate between soil / altered rock from fresh granites. As the apparent resistivity depends on the granite alteration and/or the water content, this parameter allows to estimate the relative permeability of different fracture zones. The obtained results show that the high-permeability fractures are those that are larger ones which were active during Alpine deformation (Eocene-present).

Resumen: The present work approaches incision rates quantification of Duero River in the central- west par t of Iberia and implications of tectonics in the evolution and change of drainage patterns. For this aim we calculate incision rates from the two main geomorphological surfaces defined in the area. Comparing fluvial incision rates and fracture pattern a strong structural control is shown; either in the
orientation of drainage network, either in the incision rates distribution. Drainage pattern shows two main orientations, NW-SE following the hercinian structure of the area and NE-SW to N-S matching with the main fracture sets (Duero, Almendra, Almeida-Valderaduey faults, as example). Fluvial incision is mostly controlled by the great faults and faults systems NE-SW to N-S oriented.

Resumen: Middle to Upper Pleistocene fluvial sediments of the Cádiz Bay occur fifling partly two disconnected
sub-basins excavated into shallow marine deposits of Pliocene to Lower Pleistocene age,
and are buried under fluvial and estuarine Hofocene deposits. Subsurface, drill cores, and
surface
informatio indicate that the area of the Bay was occupied by a more or less continuous basin
during the Late Pliocene-Lower Pleistocene, but the pattern changed during Middle to Late Pleistocene
as revealed by facies analysis and palaeogeographical reconstruction of the fluvial environments.
Fluvial deposits are laterally discontinuous, with variable rhickness and elongated
troughs occupied by the coarsest sediments available. Our paleogeographical reconstruction for
this periad shows a landscape with two subaerial sub-basins that acted as Fluvial valleys during glacially-forced lowstands, with two main Fluvial systems flowing constrained by topographical highs.
This configurarion records the coincidence of very low sea level (regressive conditions) during glacial
periods and active neotectonics. The valleys were flooded during the postglacial Holocene
transgression and sea level surpassed the elevations separating the former valleys leading to the
apparently simple configuration of the bay.

Resumen: El texto habla sobre los efectos producidos por las publicidad y los medios de comunicación de masas sobre los niños. Estos producen un efecto acumulativo indirecto pero muy poderoso: la desestructuración de los valores del niño y su comportamiento como un adulto precoz.
[ABSTRACT]The text studies the effects produced by the advertising and the mass media to the children, that have an indirect but very powerful cumulative effect: the dismantling of the values
of the children and its behavior, transforming them in precocious adults.

Resumen: La utilización de una red corporal de sensores inalámbricos es una posible alternativa para el cuidado de la salud que está en pleno desarrollo. Las limitaciones de memoria y
capacidad de procesamiento son uno de los mayores problemas de los nodos que componen la red, y dificultan la creación de aplicaciones capaces de ejecutarse en ellos. Hasta ahora se optaba por enviar todos los
datos recogidos, y era la estación base la que los analizaba. En este proyecto se ha conseguido integrar en una plataforma inalámbrica
diseñada por IMEC, que es capaz de leer señales ECG, un algoritmo que realiza un análisis en tiempo real de los datos leídos por los sensores y reduce notablemente el
número de transmisiones necesarias entre el nodo y la estación base. La aplicación resultante es una herramienta de autodiagnóstico lo suficientemente potente como para detectar las ondas características más importantes del ECG e
informar sobre los posibles problemas cardiacos del paciente.
[ABSTRACT]
Using a Wireless Body Sensor Networks (WBSN) is a possible alternative for healthcare that is in full swing. Limitations on memory and processing capacity are one
of the biggest problems of the nodes that make up the network, and the creation of applications able to run on them is a hard work. Up to now, the nodes sent all collected
data, and the base station analysed them. This project has successfully integrated an algorithm that performs a real-time analysis of read data by sensors into a wireless
platform designed by IMEC, which is capable of reading signals ECG, so the number of necessary transmissions between the node and the base station has been reduced.
The resulting application is a self-diagnostic tool, powerful enough to detect the most important characteristic waves of ECG and to report on any patient's heart problems.
