    Jet stability and the generation of superluminal and stationary components

    Full text link
    We present a numerical simulation of the response of an expanding relativistic jet to the ejection of a superluminal component. The simulation has been performed with a relativistic time-dependent hydrodynamical code from which simulated radio maps are computed by integrating the transfer equations for synchrotron radiation. The interaction of the superluminal component with the underlying jet results in the formation of multiple conical shocks behind the main perturbation. These trailing components can be easily distinguished because they appear to be released from the primary superluminal component, instead of being ejected from the core. Their oblique nature should also result in distinct polarization properties. Those appearing closer to the core show small apparent motions and a very slow secular decrease in brightness, and could be identified as stationary components. Those appearing farther downstream are weaker and can reach superluminal apparent motions. The existence of these trailing components indicates that not all observed components necessarily represent major perturbations at the jet inlet; rather, multiple emission components can be generated by a single disturbance in the jet. While the superluminal component associated with the primary perturbation exhibits a rather stable pattern speed, trailing components have velocities that increase with distance from the core but move at less than the jet speed. The trailing components exhibit motion and structure consistent with the triggering of pinch modes by the superluminal component.Comment: Accepted by ApJ Letters.

    Unveiling the secret of ancient Maya masons: Biomimetic lime plasters with plant extracts

    Ancient Maya produced some of the most durable lime plasters on Earth, yet how this was achieved remains a secret. Here, we show that ancient Maya plasters from Copan (Honduras) include organics and have a calcite cement with meso-to-nanostructural features matching those of calcite biominerals (e.g., shells). To test the hypothesis that the organics could play a similar toughening role as (bio)macromolecules in calcium carbonate biominerals, we prepared plaster replicas adding polysaccharide-rich bark extracts from Copan’s local trees following an ancient Maya building tradition. We show that the replicas display similar features as the organicscontaining ancient Maya plasters and demonstrate that, as in biominerals, in both cases, their calcite cement includes inter- and intracrystalline organics that impart a marked plastic behavior and enhanced toughness while increasing weathering resistance. Apparently, the lime technology developed by ancient Maya, and likely other ancient civilizations that used natural organic additives to prepare lime plasters, fortuitously exploited a biomimetic route for improving carbonate binders performanceSantander Program for the Research and Conservation of Maya Sculpture, at the David Rockefeller Center for Latin American Studies(DRCLAS), Harvard UniversitySpanish Government RTI2018-099565-B-I00 PID2021.125305NBMCIN/AEIERDF Away of making EuropeJunta de AndaluciaUniversity of GranadaUnidad Cientifica de Excelencia UCE PP2016-05Horizon 2020Marie Sklodowska-Curie Action European Training network-Innovative Training Network (ETN-ITN), SUBlime 95598

    Factores emocionales presentes en las comunidades de marca virtuales: El Caso Pokémon

    Get PDF
    Las comunidades de marca virtuales son un instrumento de gran importancia, del cual las empresas han ido tomando conciencia con el paso de los años y el avance de las tecnologías. Al tratarse de comunidades, las relaciones personales están presentes en todos sus aspectos, por lo que los factores emocionales serán vitales para su desarrollo. Con esta premisa, se comenzará con un marco teórico en el que se clarificarán los términos de comunidad de marca virtual y emoción, además de dividir ambos conceptos según sus posibles clasificaciones, y teorizar su interrelación. Posteriormente, se realizará un estudio empírico apoyado en la comunidad virtual de Pokémon, empresa que en un principio se dedicó a la creación de videojuegos, pero que, actualmente, maneja gran cantidad de actividades, convirtiéndola en una marca reconocida a nivel mundial. En el estudio se tratará de demostrar qué emociones son las más importantes, y en qué forma están presentes en la unión y participación a dichas comunidades

    Maritime Spatial Planning INSPIRE data model

    Get PDF
    Poster para CongresoThe Maritime Spatial Planning (MSP) INSPIRE data model concept has been developing from 2014, applying Infrastructure for spatial information in Europe Directive 2007/2/EC (INSPIRE) data management concepts for marine planning, through the Marine Pilot project (EC Joint Research Centre 2014-2016) and continuing with the PLASMAR project (INTERREG–V 2017-2020). The results and findings delivered have been published in the paper “Maritime spatial planning supported by infrastructure for spatial information in Europe (INSPIRE)” (Abramic et al., 2018). Currently, there are difficulties in harmonising products, visions, maps and frameworks of maritime spatial plans delivered by countries sharing the same marine (sub)region. This is mainly due to the fact that maritime plans do not use a common symbology and data structure to describe maritime activities. A solution for this issue is to apply on a marine spatial plans, INSPIRE standards for data sets, layers and portrayals. The MarSP project was a perfect opportunity to finalise conceptual data model development and, what is more important, to test results applying it on the real use cases, developed in the Macaronesia (Azores, Madeira, Canaries) MSP process. Initially, the INSPIRE data model for terrestrial planning (Planned Land Use, Figure 1) was tested to see if it could be applied for MSP. Tests pointed out that the terrestrial data model is robust, and can map MSP’s, but it tends to lose detail and specific information on marine uses. To be applied for MSP, the Planned Land Use data model needs to be adapted for planning of the maritime activities in the marine space. Conceptual model was analyzed, adapted, applying data modeling techniques, adjusting for MSP requirements: 1. Developed conceptual MSP data model, extending Planned Land use, using Unified Model Language (Figure 2); 2. Extending spatial scope of the data model - from two-dimensional land planning to the three dimensions planning. Extended structure includes maritime activities within the sea surface, water column, seabed and subsoil, when land model consists mainly of land surface planning; 3. Developed specific maritime uses classification (including register), extending Hierarchical INSPIRE Land Use classification (HILUCS); 4. Developed MSP data model templates, using simplified and feature complex spatial data architectures. Different type of codification templates, for advanced, standard and rookie GIS users (gml, GeoPackage, Shapfile, available at Canaries MSP platform); 5. Styled Layer Descriptor (color & simbology layout) for MSP, based on International Hydrographic Organization standards. 6. Data specification document v1.0 for Maritime Spatial Planning INSPIRE data model MarSP 2nd capacity building workshop was a great opportunity to test MSP data model results. Participants were trained on how to apply MSP data model on selected use case (Madeira MSP draft), during the “hands on” session, discussing potential issues and technical solutions.MarS

    The Spanish Institute of Oceanography is responsible, among other aspects, for scientifc and technical advice for the Government’s fsheries policy as well as for the protection and sustainability of the marine environment. In this task, it generates a large amount of oceanographic data characterized by its spatial dispersion during acquisition as well as by its diferent typology. The purpose of both the National Oceanographic Data Center and the GIS team is to safeguard data and to disclose what data exists and where, how and when it has been acquired and, in addition, to provide access to that data through the collaboration with diferent international data infrastructures like EMODnet or SeaDataNet. To this end, the data and metadata are subjected to quality control and formatted for integration into a national Spatial Data Infrastructure (SDI). This SDI has a GeoNetwork catalogue with ~ 1750 oceanographic campaigns, together with (meta)data and services that are continuously being revised and incorporated. All this with the ultimate goal of making the data increasingly FAIR.Peer Reviewe
