Quantitative mapping of mechanical properties in polylactic acid/natural rubber/organoclay bionanocomposites as revealed by nanoindentation with atomic force microscopy
Quantitative mapping of the mechanical properties of a series of polylactic acid/natural rubber/organoclay bionanocomposites has been accomplished by using nanoindentation with atomic force microscopy. Topography, elastic modulus and adhesion maps were obtained simultaneously revealing nanoscopic mechanical features in the samples associated to the different phases. For polylactic acid and polylactic acid/natural rubber a single distribution of Young's moduli was obtained whose maximum correlates well with the macroscopic measurements. Bionanocomposites with high organoclay loads exhibit a bimodal distribution of elastic moduli whose maxima can be associated to the polylactic acid matrix and to the reinforcing levels provided by the organoclay component. Adhesion maps allow one to obtain mechanical contrast between polylactic acid and organoclay, at high loadings, revealing the good compatibility of the organoclay with the polymer.Peer Reviewe

Mejora de la competitividad del sector de la dorada (Sparus aurata) a través de la selección genética. PNA PROGENSA-III
This project promotes technology developments for gilthead sea bream industrial sector of Spain, to facilitate and normalize the implementation of
genetic selection schemes in this species, by defining new technological traits of commercial interest, with new standardized and extensible
technological developments that permit, in an economical manner, normalized measuring methods, to study genetic parameters (growth,
morphology, carcass and resistance disease), genotype-environment interaction to extend the Spanish production, and guarantee the production
levels to the whole production chain. At the same time, improving the breeders management under industrial conditions, the validation of feeding
efficiency during the selection processes and location of biomarkers linked and applied in genomic selectionCon la presente propuesta se pretende desarrollar metodología transferible al sector industrial de dorada en España que facilite y normalice la
implementación de esquemas de selección genética en esta especie, mediante la definición de caracteres de interés comercial con nuevos desarrollos
tecnológicos que estandaricen y hagan extensible a todo el sector, de manera económica, la medición de caracteres a escala industrial, el estudio de
parámetros genéticos para caracteres de interés comercial (crecimiento, morfología, rendimiento y resistencia a enfermedades) en stocks de
reproductores de la industria española, la estimación de la interacción genotipo-ambiente para permitir de manera garante la expansión de los
rendimientos productivos de la industria Española, la gestión de reproductores bajo los propios condicionantes de la industria, así como la validación
de la eficiencia alimenticia de los procesos de selección y búsqueda de biomarcadores asociados y aplicables en los modelos de selección
The eleventh and twelfth data releases of the Sloan Digital Sky Survey : final data from SDSS-III
The third generation of the Sloan Digital Sky Survey (SDSS-III) took data from 2008 to 2014 using the original SDSS wide-field imager, the original and an upgraded multi-object fiber-fed optical spectrograph, a new nearinfrared high-resolution spectrograph, and a novel optical interferometer. All of the data from SDSS-III are now made public. In particular, this paper describes Data Release 11 (DR11) including all data acquired through 2013 July, and Data Release 12 (DR12) adding data acquired through 2014 July (including all data included in previous data releases), marking the end of SDSS-III observing. Relative to our previous public release (DR10), DR12 adds one million new spectra of galaxies and quasars from the Baryon Oscillation Spectroscopic Survey (BOSS) over an additional 3000 deg2 of sky, more than triples the number of H-band spectra of stars as part of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE), and includes repeated accurate radial velocity measurements of 5500 stars from the Multi-object APO Radial Velocity Exoplanet Large-area Survey (MARVELS). The APOGEE outputs now include the measured abundances of 15 different elements for each star. In total, SDSS-III added 5200 deg2 of ugriz imaging; 155,520 spectra of 138,099 stars as part of the Sloan Exploration of Galactic Understanding and Evolution 2 (SEGUE-2) survey; 2,497,484 BOSS spectra of 1,372,737 galaxies, 294,512 quasars, and 247,216 stars over 9376 deg2; 618,080 APOGEE spectra of 156,593 stars; and 197,040 MARVELS spectra of 5513 stars. Since its first light in 1998, SDSS has imaged over 1/3 of the Celestial sphere in five bands and obtained over five million astronomical spectra
