Real estate acquisition: real estate issues in couples

En la situación actual el acceso a la vivienda resulta más que complicado. Si además se convierte en la morada permanente y estable de la familia, la renuncia, privación o reparto de la vivienda familiar pasa a ser el foco de atención de la pareja cuando su relación entra en crisis. Con el presente trabajo pretendemos aclarar los recientes criterios jurisprudenciales a la hora de asignar la vivienda tras la ruptura del matrimonio o de la convivencia de hecho, así como la utilización de la sociedad civil y la comunidad de bienes como recursos jurídicos utilizables para compartir la titularidad de la vivienda de los convivientes no casados.It is being more difficult nowadays to purchase real estate. Furthermore, if it became the permanent and loving family home, abandonment, deprivation or division of the marital residence could be the focus of a battle for possession in the couple when they decide to end their relationship. This research paper hereon would through light on what recent case-law establishes regarding division of the real estate in the marriage or de facto couple, as well as on the use of community property as a legal resource in sharing the property in de facto couple cases.Publicad

Mid-infrared microlensing of accretion disc and dusty torus in quasars: effects on flux ratio anomalies

Multiply-imaged quasars and AGNs observed in the mid-infrared (MIR) range are commonly assumed to be unaffected by the microlensing produced by the stars in their lensing galaxy. In this paper, we investigate the validity domain of this assumption. Indeed, that premise disregards microlensing of the accretion disc in the MIR range, and does not account for recent progress in our knowledge of the dusty torus. To simulate microlensing, we first built a simplified image of the quasar composed of an accretion disc, and of a larger ring-like torus. The mock quasars are then microlensed using an inverse ray-shooting code. We simulated the wavelength and size dependence of microlensing for different lensed image types and fraction of compact objects projected in the lens. This allows us to derive magnification probabilities as a function of wavelength, as well as to calculate the microlensing-induced deformation of the spectral energy distribution of the lensed images. We find that microlensing variations as large as 0.1 mag are very common at 11 microns (observer-frame). The main signal comes from microlensing of the accretion disc, which may be significant even when the fraction of flux from the disc is as small as 5 % of the total flux. We also show that the torus of sources with Lbol <~ 10^45 erg/s is expected to be noticeably microlensed. Microlensing may thus be used to get insight into the rest near-infrared inner structure of AGNs. Finally, we investigate whether microlensing in the mid-infrared can alter the so-called Rcusp relation that links the fluxes of the lensed images triplet produced when the source lies close to a cusp macro-caustic. This relation is commonly used to identify massive (dark-matter) substructures in lensing galaxies. We find that significant deviations from Rcusp may be expected, which means that microlensing can explain part of the flux ratio problem.Comment: Updated to match the version published in Astronomy and Astrophysics. 12 pages.

Experimental ratchet effect in superconducting films with periodic arrays of asymmetric potentials

A vortex lattice ratchet effect has been investigated in Nb films grown on arrays of nanometric Ni triangles, which induce periodic asymmetric pinning potentials. The vortex lattice motion yields a net dc-voltage when an ac driving current is applied to the sample and the vortex lattice moves through the field of asymmetric potentials. This ratchet effect is studied taking into account the array geometry, the temperature, the number of vortices per unit cell of the array and the applied ac currents.Comment: 15 pages, figures include

Organización de la asignatura de nuevas tecnologías aplicadas a la educación con una herramienta telemática colaborativa (BSCW).

Partiendo de la estructura y la organización curricular de la asignatura de Nuevas Tecnologías Aplicadas a la Educación y de la idea educativa central sobre la que se organiza, como es la colaboración entre el alumnado, se expone una experiencia que se está llevando a cabo con la misma utilizando una herramienta telemática que permite el trabajo colaborativo, BSCW. Este trabajo pretende ser un documento de debate y reflexión acerca del uso de esta herramienta telemática colaborativa en un contexto docente determinado, que es el de la asignatura de Nuevas Tecnologías Aplicadas a la Educación de los títulos de maestro en la Facultad de Educación de la Universidad de Valladolid. Queremos dejar claro, por tanto, que no se ha realizado una investigación exhaustiva y rigurosa sobre la aplicación de dicha herramienta, sino que se trata de describir en un documento de debate los pasos que hemos ido dando y algunas de las posibilidades que se pueden abrir desde una perspectiva didáctica y docente.Starting from the structure and the curricular organization of the subject ʺNew Technologies applied to educationʺ, and understanding the collaboration as one of the main objectives to reach, we display an experience in which a telematic tool, BSCW, supports the collaborative work among the students of it. This paper intends to be a document of debate and reflection about the use of this collaborative tool in a determined teaching context, the New Technologies applied to education subject in teacherʹs studies in the Faculty of Education in the University of Valladolid. Therefore we want to leave obvious, that we did not make an exhaustive and rigorous investigation on the application of the mentioned tool, rather we try to describe the steps we have gone giving and some of the possibilities that can be expand from a didactic perspective

Lattice effects and current reversal in superconducting ratchets

Competition between the vortex lattice and a lattice of asymmetric artificial defects is shown to play a crucial role in ratchet experiments in superconducting films. We present a novel and collective mechanism for current reversal based on a reconfiguration of the vortex lattice. In contrast to previous models of vortex current reversal, the mechanism is based on the global response of the vortex lattice to external forces.Comment: 12 pages, 7 figure

Traditión and innovation along the 2nd Millennium B.C. in the central Guadalquivir region: I. The funerary rituals

Una cultura debe contener un conjunto de items normalizados que nos permitan reconocerla en su extensión territorial, y por sus cambios, establecer su secuencia interna. Con este argumento trataremos los yacimientos arqueológicos, ya clásicos en el valle bético; en este trabajo valoraremos las necrópolis y analizaremos en otro momento la secuencia de los poblados, durante el II milenio a.C., empleando como criterio organizador la cronología, fundamentalmente la absoluta, cuando ello sea posible.Ancient cultures must hold an ensemble of normalized items, which allow us to locate it in its territorial area and, leaning on its changes, to establish its sequence. According to this argument we will consider main archaeological sites in Andalusian Valley. In this essay we will assess necropolis and analyze the village’s sequence during II B.C. using dating as organizing criteria, absolute dating when possibl
