Maternidad subrogada: controversias éticas y legislativas

El presente trabajo tiene por objeto analizar la maternidad subrogada desde un punto de vista jurídico y ético. El nacimiento de las técnicas de reproducción asistida en estas últimas décadas ha generado una gran controversia al dotar de ciertos mecanismos alternativos a aquellas personas que por causas naturales no pueden ver satisfecho su deseo de ser padres. Como consecuencia del mundo global actual en el que vivimos y la diferente aceptación que han tenido estas técnicas en cada Estado, ha dado lugar a un turismo reproductivo descontrolado generando inseguridad jurídica y sobretodo una incertidumbre respecto la determinación de la filiación para los sujetos que demandan estos servicios. Es evidente que ante esta situación, lograr una regulación garante de todos los valores y principios amparados por la Constitución y a su vez, de todos los sujetos intervinientes en el convenio gestacional no es tarea fácil debido a las numerosas modalidades de maternidad subrogada existentes y los diferentes enfoques desde los que se la analiza dando lugar a numerosas opiniones y diversas formas de concebir las técnicas de reproducción asistida.Departamento de Derecho Penal e Historia y Teoría del DerechoGrado en Derech

Star Formation in the Bok Globule CB54

We present mid-infrared (10.4, 11.7, and 18.3 μm) imaging intended to locate and characterize the suspected protostellar components within the Bok globule CB54. We detect and confirm the protostellar status for the near-infrared source CB54YC1-II. The mid-infrared luminosity for CB54YC1-II was found to be L_(midir) ≈ 8 L_⊙, and we estimate a central source mass of M_* ≈ 0.8 M_⊙ (for a mass accretion rate of M = 10^(-6) M yr^(-1)). CB54 harbors another near-infrared source (CB54YC1-I), which was not detected by our observations. The nondetection is consistent with CB54YC1-I being a highly extinguished embedded young A or B star or a background G or F giant. An alternative explanation for CB54YC1-I is that the source is an embedded protostar viewed at an extremely high inclination angle, and the near-infrared detections are not of the central protostar, but of light scattered by the accretion disk into our line of sight. In addition, we have discovered three new mid-infrared sources, which are spatially coincident with the previously known dense core in CB54. The source temperatures (~100 K) and association of the mid-infrared sources with the dense core suggests that these mid-infrared objects may be embedded class 0 protostars

Geoenvironmental Characterization of Sulfide Mine Tailings

Spain has a long mining tradition dating from pre-historic times up to the present day. The cessation of mining activity has generated a large amount of mine wastes, most of which represent geochemical hazards. Mine tailings are watery sludge composed of medium-to-fine-grained material, resulting from grinding and mineral processing (e.g., galena, pyrite, sphalerite, and arsenopyrite). They entail both an accumulation and a potential subsequent emission source of trace elements (i.e. As, Cu, Fe, Pb, and Zn) with formation of acid mine drainage (AMD). Mineralogical and geochemical techniques (in combination with geophysical surveys and aerial photographs studies) have been jointly applied to selected mine areas. Seven mine deposits from the most important mine districts in Spain have been selected: Iberian Pyrite Belt, Cartagena-La Unión, Alcudia Valley, and Mazarrón. The main goal is focused on getting a geoenvironmental characterization as complete as possible by determining the geometry, evolution in time and composition of mine ponds, and the possible occurrence of AMD, for identifying related environmental hazards

Ingeniería eléctrica en el campus virtual andaluz y su proyección hacia el espacio europeo de educación superior

The aim of this article is to describe the implementation of the subject Electrical Technology in the new Campus Virtual Andaluz as a pilot experiment run by the Andalusian Regional Government for the university community. We will then analyse the advantages of this experiment and finally, we will discuss how to proceed in the future, implementing this subject in English (due to its importance as a lingua franca), which would give it international status and comply with guidelines issued by the European Higher Education Area.El objetivo de este artículo es describir la implementación virtual de la asignatura Tecnología Eléctrica que se incardina en el nuevo proyecto del Campus Virtual Andaluz como una experiencia piloto puesta en marcha por la Junta de Andalucía para la comunidad universitaria. Pasaremos, después, a analizar las ventajas de esta experiencia y, finalmente, estableceremos las bases para las líneas de actuación futuras implementando esta asignatura en inglés (debido a su consideración como lengua franca), de forma que tenga un estatus internacional y, así pueda adaptarse a las directrices del Espacio Europeo de Educación Superior

An upper bound for the magnetic force gradient in graphite

Cervenka et al. have recently reported ferromagnetism along graphite steps. We present Magnetic Force microscopy (MFM) data showing that the signal along the steps is independent of an external magnetic field. Moreover, by combining Kelvin Probe Force Microscopy (KPFM) and MFM, we are able to separate the electrostatic and magnetic interactions along the steps obtaining an upper bound for the magnetic force gradient of about16 microN/m, a figure six times lower than the lowest theoretical bound reported by Cervenka et al. Our experiments suggest absence of MFM signal in graphite at room temperature.Comment: 14 pages, including supplemetary informatio

Clustering, dispersion and sociodemographics characteristics in the spatial incorporation of Peruvians migrants in Córdoba, Argentina

Analizar los patrones espaciales de la migración peruana en la Ciudad de Córdoba, Argentina y comparar la población nacida en Perú que se encuentra agrupada en clústers con aquella dispersa en la ciudad. Se utilizaron técnicas de estadística espacial y análisis sociodemográfico. En la primera fase se usaron medidas globales de autocorrelación espacial (índice global de Moran) y medidas locales de agrupación espacial para representar clústers de población (Gi* de Getis Ord). En la segunda fase se realiza un análisis sociodemográfico de los clústers de población agrupada y dispersa. Resultados:se sugiere la interacción de dos procesos. En primer lugar, la concentración en zonas específicas de la ciudad de migrantes peruanos en patrones que no son aleatorios. Migrantes más antiguos se encuentran principalmente dispersos en la ciudad mientras migrantes más recientes se encuentran concentrados. En segundo lugar, los migrantes peruanos hombres dispersos tienen una mayor diversificación en cuanto a la estructura ocupacional y una mejor posición socioeconómica que los agrupados. Los patrones observados sugieren que existen diferenciales de género en estos procesos. Las mujeres, tanto las que se encuentran dispersas como las agrupadas, presentan una situación socioeconómica más precaria que los hombres. Esa situación es transversal a la dispersión/concentración en el espacio urbano. Conclusiones:se sugiere que las composiciones de clase, género y la temporalidad de los flujos migratorios articulan las modalidades de incorporación a la sociedad de destino.To analyze the spatial patterns of Peruvian migration in the city of Cordoba, Argentina and to compare the Peruvian migrants in clusters with Peruvian migrants scattered in the city. Spatial statistical techniques and socio-demographic analysis are used for this analysis. In the first phase, global measures of spatial autocorrelation (Global Moran Index) and local measures of spatial clustering represent clusters of population (Getis-Ord Gi*). In the second phase, a sociodemographic analysis of population in clusters and population dispersed is carried out. Results:we suggest there are two entangled processes. First, the concentration in specific areas of the city of Peruvian migrants in patterns that are not random. Older migrants are mainly dispersed in the city while more recent migrants are concentrated. Second, dispersed Peruvian men have greater diversification in terms of occupational structure and better socioeconomic status than Peruvian migrants dispersed. Women both dispersed and in clusters have a more precarious economic situation than men. This situation is transversal to the dispersion / concentration in urban space. It is suggested that the composition of class, gender and temporality of migration flows articulate the modalities of incorporation in the society of destination.Fil: Gómez, Pablo Martín Sebastian.

Traffic scene awareness for intelligent vehicles using ConvNets and stereo vision

In this paper, we propose an efficient approach to perform recognition and 3D localization of dynamic objects on images from a stereo camera, with the goal of gaining insight into traffic scenes in urban and road environments. We rely on a deep learning framework able to simultaneously identify a broad range of entities, such as vehicles, pedestrians or cyclists, with a frame rate compatible with the strict requirements of onboard automotive applications. Stereo information is later introduced to enrich the knowledge about the objects with geometrical information. The results demonstrate the capabilities of the perception system for a wide variety of situations, thus providing valuable information for a higher-level understanding of the traffic situation

Fast Joint Object Detection and Viewpoint Estimation for Traffic Scene Understanding

Environment perception is a critical enabler for automated driving systems since it allows a comprehensive understanding of traffic situations, which is a requirement to ensure safe and reliable operation. Among the different applications, obstacle identification is a primary module of the perception system. We propose a vision-based method built upon a deep convolutional neural network that can reason simultaneously about the location of objects in the image and their orientations on the ground plane. The same set of convolutional layers is used for the different tasks involved, avoiding the repetition of computations over the same image. Experiments on the KITTI dataset show that our efficiency-oriented method achieves state-of-the-art accuracies for object detection and viewpoint estimation, and is particularly suitable for the recognition of traffic situations from on-board vision systems.
