    Han pasado veinte años de la entrada en vigor del Plan de Ordenación del Territorio de la Aglomeración Urbana de Granada (1999), el plan de mayor repercusión espacial, urbanística y ambiental de este ámbito. No son pocas las voces que demandan una revisión del mismo, habida cuenta de las transformaciones sobrevenidas desde entonces; transformaciones que se han hecho patentes en los resultados obtenidos de su seguimiento y evaluación periódicos. El último de estos informes sostiene la necesidad de revisar el POTAUG, circunstancia que ha sido refrendada por el Parlamento de Andalucía en febrero de 2018. Es por ello que el objetivo de este artículo es valorar la verdadera necesidad y urgencia de su revisión y, en última instancia, esbozar la forma en la que esta revisión debiera realizarse, a fin de consolidar los logros obtenidos, acabar de cumplir las propuestas que aún se consideren vigentes y resolver los nuevos retos ante los que se enfrenta la Aglomeración Urbana de Granada.Twenty years have passed since the Territorial Plan of the Urban Agglomeration of Granada (1999) came into force, the plan with the greatest spatial, urban and environmental impact in this area. There are many voices that demand a revision of it, given the transformations that have taken place since then; transformations that have become evident in the results obtained from its periodic monitoring and evaluation. The last of these reports supports the need to review the POTAUG, a circumstance that has been endorsed by the Parliament of Andalusia in February 2018. That is why the objective of this article is to assess whether its revision is really necessary and, ultimately, outline the way in which this revision should be carried out, in order to consolidate the achieved achievements, to finish fulfilling the proposals that are still considered valid and to solve the new challenges faced by the Urban Agglomeration of Granada

    Andalusia is the southernmost region of continental Europe, one of which has the longest coastline and the only one that shares the coastline with the Atlantic Ocean and the Mediterranean Sea. These excellent geographical conditions have given it a leading role in history and have had great economical impact. But the strong dynamism that the Andalusian coast has undergone in the last half century represents a menace to its identity, putting its economic potential at risk and producing an irreversible environmental impact. Hence it is more necessary than ever to undertake protection from planning. To this end, the Autonomous Government has approved the Plan de Protección del Corredor Litoral de Andalucía, a plan that seeks to harmonize the development of the coastal zone with its economic, environmental and landscape sustainability. However, after an exhaustive evaluation of the Plan’s proposals, it is inferred that its implementation on the coastal strip coinciding with the less dynamic and more recently intensively occupied province of Granada could lead to some adverse or undesirable effects which would need to be reviewed.Andalucía es la región más meridional de la Europa continental, una de las que cuenta con mayor longitud de costa y la única que comparte fachada litoral con el Océano Atlántico y el Mar Mediterráneo. Estas excelentes condiciones geográficas le han deparado un importante papel histórico y le han sido de gran repercusión económica. Pero el fuerte dinamismo al que se ha sometido la costa andaluza en el último medio siglo amenaza con borrar la huella de esa identidad, hipotecar su potencialidad económica y producir un impacto medioambiental irreversible. De ahí que sea más necesario que nunca emprender su protección desde la planificación. Para ello, el Gobierno Autonómico ha aprobado el Plan de Protección del Corredor Litoral de Andalucía, un plan que pretende compatibilizar el desarrollo de la zona costera con su sostenibilidad económica, ambiental y paisajística. Sin embargo, tras una exhaustiva evaluación de las propuestas del Plan, se infiere que su implementación en la franja litoral coincidente con la provincia de Granada, la menos dinámica y más recientemente ocupada de forma intensa, pudiera dar lugar a algunos efectos adversos o no deseados que necesitarían ser revisados.L’Andalousie est la région la plus méridionale de l’Europe continentale. Celle-ci compte une des plus longues côtes et elle représente la seule région de l’Europe qui partage la ligne côtière de l’océan Atlantique et de la mer Méditerranée. Ces conditions géographiques excellentes lui ont apportée un rôle important du point de vue historique et un grand impact économique. Pourtant, à cause du fort dynamisme subi par la côte andalouse pendant le dernier demi-siècle, elle risque d´effacer la trace de son identité, d´entraver son potentiel économique et de produire un impact environnemental irréversible. En conséquent, il est nécessaire de procéder à sa protection plus que jamais moyennant l´aménagement du territoire. Dans ce but, le gouvernement régional a approuvé le Plan de Protección del Corredor Litoral de Andalucía, lequel vise à concilier le développement de la zone côtière avec la viabilité économique, écologique et paysagère. Cependant, après une évaluation approfondie des propositions concernant le Plan, il en résulte que sa mise en œuvre dans le littoral de Granada, qui est le moins dynamique et qui a enduré la occupation urbaine la plus récente et intense, pourrait conduire à des effets néfastes et indésirables. C´est pour cette raison que ces effets devraient être vérifiés

    On-Surface Thermal Stability of a Graphenic Structure Incorporating a Tropone Moiety

    On-surface synthesis, complementary to wet chemistry, has been demonstrated to be a valid approach for the synthesis of tailored graphenic nanostructures with atomic precision. Among the different existing strategies used to tune the optoelectronic and magnetic properties of these nanostructures, the introduction of non-hexagonal rings inducing out-of-plane distortions is a promising pathway that has been scarcely explored on surfaces. Here, we demonstrate that non-hexagonal rings, in the form of tropone (cycloheptatrienone) moieties, are thermally transformed into phenyl or cyclopentadienone moieties upon an unprecedented surface-mediated retro–Buchner-type reaction involving a decarbonylation or an intramolecular rearrangement of the CO unit, respectivel

    Few-layer antimonene electrical properties

    Antimonene -a single layer of antimony atoms- and its few layer forms are among the latest additions to the 2D mono-elemental materials family. Numerous predictions and experimental evidence of its remarkable properties including (opto)electronic, energetic or biomedical, among others, together with its robustness under ambient conditions, have attracted the attention of the scientific community. However, experimental evidence of its electrical properties is still lacking. Here, we characterized the electronic properties of mechanically exfoliated flakes of few-layer (FL) antimonene of different thicknesses (∼ 2–40 nm) through photoemission electron microscopy, kelvin probe force microscopy and transport measurements, which allows us to estimate a sheet resistance of ∼ 1200 Ω sq−1 and a mobility of ∼ 150 cm2V−1s−1 in ambient conditions, independent of the flake thickness. Alternatively, our theoretical calculations indicate that topologically protected surface states (TPSS) should play a key role in the electronic properties of FL antimonene, which supports our experimental findings. We anticipate our work will trigger further experimental studies on TPSS in FL antimonene thanks to its simple structure and significant stability in ambient environmentsWe acknowledge financial support through the “Maríade Maeztu” Programme for Units of Excellence in R&D (CEX2018-000805-M), the Spanish MINECO through projects PCI2018-093081, FIS2016-80434-P, PID2019-109539GB-C43, PID2019- 106268GB-C31 and -C32, MAT2016-77608-C3-1-P and -3-P, MAT2013-46753-C2-2-P and MAT2017-85089-C2-1R, the EU Graphene Flagship funding (Graphene Flagship Core3 881603 and JTC2017/2D-Sb&Ge), the EU via the ERC-Synergy Program (GrantERC-2013-SYG-610256 NANOCOSMOS), the Comunidad Autónoma de Madrid through MAD2D-CM, S2018/NMT-4321 (NanomagCOST-CM) and the European StructuralFunds via FotoArt CM project (S2018/NMT-4367), and the Fundación Ramón Areces.

    Measurement of exclusive Υ photoproduction from protons in pPb collisions at √sNN=5.02TeV

    Get PDF
    The exclusive photoproduction of Υ(nS) meson states from protons, γp→Υ(nS)p (with n=1,2,3), is studied in ultraperipheral pp Pb collisions at a centre-of-mass energy per nucleon pair of √sNN=5.02TeV . The measurement is performed using the Υ(nS)→μ+μ− decay mode, with data collected by the CMS experiment corresponding to an integrated luminosity of 32.6nb−1. Differential cross sections as functions of the Υ(nS) transverse momentum squared p2T, and rapidity y, are presented. The Υ(1S) photoproduction cross section is extracted in the rapidity range |y|<2.2, which corresponds to photon–proton centre-of-mass energies in the range 91<Wγp<826GeV. The data are compared to theoretical predictions based on perturbative quantum chromodynamics and to previous measurements

    Search for a W´ boson decaying to a τ lepton and a neutrino in proton-proton collisions at √s = 13 TeV

    Get PDF
    A search for a new high-mass resonance decaying to a τ lepton and a neutrino is reported. The analysis uses proton-proton collision data collected by the CMS experiment at the LHC at √s = 13 TeV, corresponding to an integrated luminosity of 35.9 fb−1. The search utilizes hadronically decaying τ leptons. No excess in the event yield is observed at high transverse masses of the τ and missing transverse momentum. An interpretation of results within the sequential standard model excludes W boson masses below 4.0 TeV at 95% confidence level. Existing limits are also improved on models in which the W´ boson decays preferentially to fermions of the third generation. Heavy W bosons with masses less than 1.7–3.9 TeV, depending on the coupling in the non-universal G(221) model, are excluded at 95% confidence level. These are the most stringent limits on this model to date

    Search for a low-mass τ−τ+ resonance in association with a bottom quark in proton-proton collisions at √s = 13 TeV

    A general search is presented for a low-mass τ−τ+ resonance produced in association with a bottom quark. The search is based on proton-proton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 fb−1. The data are consistent with the standard model expectation. Upper limits at 95% confidence level on the cross section times branching fraction are determined for two signal models: a light pseudoscalar Higgs boson decaying to a pair of τ leptons produced in association with bottom quarks, and a low-mass boson X decaying to a τ-lepton pair that is produced in the decay of a bottom-like quark B such that B → bX. Masses between 25 and 70 GeV are probed for the light pseudoscalar boson with upper limits ranging from 250 to 44 pb. Upper limits from 20 to 0.3 pb are set on B masses between 170 and 450 GeV for X boson masses between 20 and 70 GeV

    En el taller se han realizado más de 20 presentaciones acerca de los estudios sobre las pesquerías artesanales y recreativas en aguas de la ZEE de España. En base a ello y al conocimiento de los expertos reunidos se han definido dos planes de seguimiento para obtener la huella pesquera de las pesquerías profesionales sin VMS, uno con sistemas de seguimientos de localización en tres fases y otro con observadores a bordo y encuestas en puntos de primera venta en dos fases. En el caso de las actividades pesqueras no profesionales (recreativas) se ha propuesto un plan de seguimiento basado en encuestas telefónicas y presenciales en tres fases. Además se decidió incluir las actividades pelágicas y/o de superficie dentro de los programas de seguimiento

    Effects of Albumin Treatment on Systemic and Portal Hemodynamics and Systemic Inflammation in Patients With Decompensated Cirrhosis

    BACKGROUND & AIMS: We investigated the effect of albumin treatment (20% solution) on hypoalbuminemia, cardiocirculatory dysfunction, portal hypertension, and systemic inflammation in patients with decompensated cirrhosis with and without bacterial infections. METHODS: We performed a prospective study to assess the effects of long-term (12 weeks) treatment with low doses (1 g/kg body weight every 2 weeks) and high doses (1.5 g/kg every week) of albumin on serum albumin, plasma renin, cardiocirculatory function, portal pressure, and plasma levels of cytokines, collecting data from 18 patients without bacterial infections (the Pilot-PRECIOSA study). We also assessed the effect of short-term (1 week) treatment with antibiotics alone vs the combination of albumin plus antibiotics (1.5 g/kg on day 1 and 1 g/kg on day 3) on plasma levels of cytokines in biobanked samples from 78 patients with bacterial infections included in a randomized controlled trial (INFECIR-2 study). RESULTS: Circulatory dysfunction and systemic inflammation were extremely unstable in many patients included in the Pilot-PRECIOSA study; these patients had intense and reversible peaks in plasma levels of renin and interleukin 6. Long-term high-dose albumin, but not low-dose albumin, was associated with normalization of serum level of albumin, improved stability of the circulation and left ventricular function, and reduced plasma levels of cytokines (interleukin 6, granulocyte colony-stimulating factor, interleukin 1 receptor antagonist, and vascular endothelial growth factor) without significant changes in portal pressure. The immune-modulatory effects of albumin observed in the Pilot-PRECIOSA study were confirmed in the INFECIR-2 study. In this study, patients given albumin had significant reductions in plasma levels of cytokines. CONCLUSIONS: In an analysis of data from 2 trials (Pilot-PRECIOSA study and INFECIR-2 study), we found that albumin treatment reduced systemic inflammation and cardiocirculatory dysfunction in patients with decompensated cirrhosis. These effects might be responsible for the beneficial effects of albumin therapy on outcomes of patients with decompensated cirrhosis. ClinicalTrials.gov, Numbers: NCT00968695 and NCT03451292
