La antropología jurídica y el derecho consuetudinario como constructor de realidades sociales

The Juridical Anthropology and the practices and customary customs, central topic of the text, it is treated from areas like the cultures of the water and the traditional systems of irrigation; the sustainable management of the common property; the modalities of familiar institution and the ways of administering his goods specially in the moment to test, stopping in customary institutions as Baylío’s Jurisdiction and the couple branch - acetuao. Under the juridical custom there sublies the model of the systems of reciprocity. From the empirical base of the ethnographic fieldwork realized in Estremadura there appear other significant variables relatedto the studies concerning the juridical custom, such as the systems of values, the religion and the systems ideáticos, the social structures, the studies of kind and the environmental ones.La Antropología Jurídica y las prácticas y costumbres consuetudinarias, tema central del texto, es tratada desde ámbitos como las culturas del agua y los sistemas tradicionales de regadío; la gestión sostenible de los bienes comunales; las modalidades de institución familiar y las formas de administrar sus bienes especialmente en el momento de testar, deteniéndonos en instituciones consuetudinarias como el Fuero de Baylío y el par hijuela-acetuao. Bajo la costumbre jurídica subyace el modelo de los sistemas de reciprocidad. A partir de la base empírica del trabajo de campo etnográfico realizado en Extremadura se plantean otras variables significativas relacionadas con los estudios en torno a la costumbre jurídica, tales como los sistemas de valores, la religión y los sistemas ideáticos, las estructuras sociales, los estudios de género y los medioambientales

The fractal dimension of star-forming regions at different spatial scales in M33

We study the distribution of stars, HII regions, molecular gas, and individual giant molecular clouds in M33 over a wide range of spatial scales. The clustering strength of these components is systematically estimated through the fractal dimension. We find scale-free behavior at small spatial scales and a transition to a larger correlation dimension (consistent with a nearly uniform distribution) at larger scales. The transition region lies in the range 500-1000 pc. This transition defines a characteristic size that separates the regime of small-scale turbulent motion from that of large-scale galactic dynamics. At small spatial scales, bright young stars and molecular gas are distributed with nearly the same three-dimensional fractal dimension (Df <= 1.9), whereas fainter stars and HII regions exhibit higher values (Df = 2.2-2.5). Our results indicate that the interstellar medium in M33 is on average more fragmented and irregular than in the Milky Way.Comment: 18 pages including 4 figures. Accepted for publication in Ap

Combination of XANES spectroscopy and molecular dynamics to probe the local structure in disordered systems

Individual configurations obtained from molecular dynamics have been combined with the computation of x-ray absorption near-edge structure (XANES) spectra to obtain a theoretical estimation of the spectrum corresponding to a system in a condensed medium lacking long-range order. The influence of the different geometries on the spectrum is studied. The results obtained indicate that the reproduction of the features of the XANES spectrum requires a good sampling of geometrical arrangements. As a test case, an aqueous solution of Cr(H2O)6 3+ was selected, since its simulation reproduces well structural results. The contribution of the second hydration shell on the shape of the spectrum was determined.Dirección General de Investigación Científica y Técnica IFD97-118

Technological Ecosystems in the Health Sector: a Mapping Study of European Research Projects

The European Union has a substantial investment in research and development and demand side-measures in the health sector in order to promote new initiatives, prevent disease and foster healthy lifestyles. In particular, the European Commission and other European entities have funded research projects focused on the use of technology in the health sector. In this context, health research initiatives have evolved from user-centred monolithic solutions into collaborative partnerships of different stakeholders that gather around different technological platforms. In order to identify the lacks and opportunities in this area, a systematic mapping study was conducted with the aim of identifying and analysing the recent research projects developed in Europe related to technological ecosystems in the health sector. The study covered closed European research projects from 2003 to 2018. This paper aims to extend that systematic mapping study through ongoing research projects. The analysis of these research projects provides an overview of the current trends and identify the lacks and opportunities to define new advances in this research area. Moreover, the comparison between the first mapping study focused on closed projects, and the current study, allows getting an overview of the evolution of technological ecosystems in the health sector

Exact solutions for transient mixing of two gases of different densities

This Brief Communication presents a number of exact solutions describing the transient mixing of two gases of different molecular weights. Descriptions are given for both the concentration field and the associated induced motion in one-dimensional spherical, cylindrical, and planar configurations, including mixing layers, pockets, coflow jets, and concentrated mass sources

Cation distribution of cobalt ferrite electrosynthesized nanoparticles: A methodological comparison

Final publication at http://doi.org/10.1016/j.jallcom.2017.12.342, © 2017 Elsevier B.V.The present work seeks to analyse the structural and magnetic properties of cobalt ferrite nanoparticles obtained by electrochemical synthesis by high-resolution transmission electronic microscopy (HRTEM), X-ray absorption spectroscopy (XAS), Mössbauer spectroscopy (MS), neutron diffraction (ND) and SQUID magnetometer. The cationic distribution is analyzed by different techniques. The inversion degree determined by the most accurate measurements was 0.73(1), and the formula for the nanoparticles therefore was (↑Co 0.27 Fe 0.73 )[↓Co 0.73 Fe 1.27 ]O 4 . The magnetic moment found from DC and Mössbauer spectroscopy measurements was 3.8(3) μB, and the coercivity was 7870 Oe at 100 K.This work is supported by the MINECO/FEDER Project MAT2015-67557-C2-2-

Molecular-dynamics-based investigation of scattering path contributions to the EXAFS spectrum: The Cr3¿ aqueous solution case

Extended x-ray absorption fine structure spectra were computed based on molecular-dynamics (MD) struc- tural data of a [ Cr(H2O)6 ]3+ aqueous solution using nonempirical cation-water potentials. An excellent re- production of the experimental spectrum was achieved. A simple estimation of Debye-Waller factors of the multiple-scattering paths is deduced from MD simulations. The influence of the single-scattering path due to the second hydration shell as compared with the multiple-scattering paths within the first hydration shell allows a reasonable determination of the second hydration shell distance R(Cr-OII) within 0.1 Å
