[EN] Plant communities are complex and dynamic elements of the landscape, intertwined with both natural factors and human activities. Vegetation series reflect the environmental characteristics of the landscape, but also the anthropic impact, one of the exogenous forces that most profoundly affects the landscape formation process. This paper aims to investigate the interactions between long-term human settlement catchment areas and vegetation series. The case study area of the Sicani Mountains (Central-Western Sicily) proved to be an ideal place to perform GIS-based spatial analysis in order to compare a data set of rural archaeological sites and land units created through the mapping of vegetation series. The existence of a causal link between vegetation series and human settlement patterns allows us, as well as future researchers, to find new explanations for the formation of the multifaceted Mediterranean rural landscape., We would like to express our gratitude to Steve Luczo, owner of Bona Furtuna LLC, who entirely supported and funded the project ‘Harvesting Memories: Ecology and Archaeology of Monti Sicani landscapes (Central-Western Sicily)’.

It has been suggested that dust storms efficiently transport water vapor from the near-surface to the middle atmosphere on Mars. Knowledge of the water vapor vertical profile during dust storms is important to understand water escape. During Martian Year 34, two dust storms occurred on Mars: a global dust storm (June to mid-September 2018) and a regional storm (January 2019). Here we present water vapor vertical profiles in the periods of the two dust storms (Ls = 162–260° and Ls = 298–345°) from the solar occultation measurements by Nadir and Occultation for Mars Discovery (NOMAD) onboard ExoMars Trace Gas Orbiter (TGO). We show a significant increase of water vapor abundance in the middle atmosphere (40–100 km) during the global dust storm. The water enhancement rapidly occurs following the onset of the storm (Ls~190°) and has a peak at the most active period (Ls~200°). Water vapor reaches very high altitudes (up to 100 km) with a volume mixing ratio of ~50 ppm. The water vapor abundance in the middle atmosphere shows high values consistently at 60°S-60°N at the growth phase of the dust storm (Ls = 195°–220°), and peaks at latitudes greater than 60°S at the decay phase (Ls = 220°–260°). This is explained by the seasonal change of meridional circulation: from equinoctial Hadley circulation (two cells) to the solstitial one (a single pole-to-pole cell). We also find a conspicuous increase of water vapor density in the middle atmosphere at the period of the regional dust storm (Ls = 322–327°), in particular at latitudes greater than 60°S. ©2019.

CMS Collaboration: et al., Measurements of the top quark polarization and top quark pair (tt) spin correlations are presented using events containing two oppositely charged leptons (e+e-, e±μ or μ+μ-) produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC in 2016 and correspond to an integrated luminosity of 35.9 fb-1. A set of parton-level normalized differential cross sections, sensitive to each of the independent coefficients of the spin-dependent parts of the tt production density matrix, is measured for the first time at 13 TeV. The measured distributions and extracted coefficients are compared with standard model predictions from simulations at next-to-leading-order (NLO) accuracy in quantum chromodynamics (QCD), and from NLO QCD calculations including electroweak corrections. All measurements are found to be consistent with the expectations of the standard model. The normalized differential cross sections are used in fits to constrain the anomalous chromomagnetic and chromoelectric dipole moments of the top quark to -0.24, Rachada-pisek Individuals have received support from the Marie-Curie program and the European Research Council and Horizon 2020 Grant, contract Nos. 675440, 752730, and 765710 (European Union); the Programa Estatal de Fomento de la Investigación Científica y Tecnica de Excelencia María de Maeztu, grant No. MDM-2015-0509 and the Programa Severo Ochoa del Principado de Asturias.

Resumen del póster presentado al Microscopy at the Frontiers of Science Congress Series (MFS), celebrado en el Parque de las Ciencias de Granada (España) del 11 al 13 de septiembre de 2019., One of the current endeavors in quantum technology consists of the development of topological quantum computers, which stand out as promising candidates because, contrary to the quantum states of ordinary individually trapped particles such as electrons, the topological properties of the quantum system ensure a higher stability when subjected to small perturbations. Among the different classes of topological states, the so-called Majorana bound states are of great interest, as signatures of their appearance have been observed recently in hybrid III-V semiconductor superconductor nanowires. A way to induce the topological properties, without the need of external magnetic fields that could modify the band structure of the nanowire, is given by the coupling to ferromagnetic insulators. Composite tri-crystals of semiconductor-ferromagnetic insulator-superconductor materials, such as InAs-EuS-Al, have been proposed to overcome the challenge of building adequate topological systems, where the absence of crystal defects and impurities, particularly at the interfaces between materials, is of extreme importance. Therefore, our work is centered around the study of the crystal quality of the nanostructures, especially focusing on the epitaxial relationship between the composing materials. Mainly by the means of High-angle annular dark-field (HAADF) imaging in Scanning Transmission Electron Microscopy (HAADF-STEM), where we analyze the crystal phases and interfaces at atomic scale and check the coupling of different materials atom by atom (column), combined with Electron Energy Loss Spectroscopy (EELS) in order to gain data on the chemical composition distribution, we study nanostructures grown by different techniques, in varying geometrical layouts and growth conditions. Namely, we have analyzed vertically grown nanowires of InAs by the Vapor-Liquid-Solid (VLS) method, with selective covering of the several facets with EuS and Al to observe possible favored crystal orientations depending on the faceting, planar samples of EuS layers grown on InAs by Molecular Beam Epitaxy (MBE), which is the preferred synthesis method due to its ultra-pure environment, and also the growth of InAs on GaAs substrate in the form of nanowires forming networks created by the method of Selective Area Growth (SAG)7-10, since the development of said networks is one of the final goals for the construction of the logic gates used for the calculations in a topological quantum computer. By applying Geometric Phase Analysis (GPA) to HAADF-STEM micrographs with atomic resolution, we are able to detect structural defects and deformations, such as twin boundaries, misfit dislocations, rotation and compression/dilatation within the crystal phases of these nanostructures.

[EN] The genus Equus is the last member of the Equidae family whose evolutionary history is about 55 million years. This horse is abundant in Mexican Pleistocene deposits. Elements of the distal extremities (third metacarpals and metatarsals, first and second phalanx of the third digit) of three horse species (Equus cedralensis, E. conversidens and E. mexicanus) from three localities of Mexican Rancholabrean (0.21-0.16 a 0.095 Ma) were analyzed using geometric morphometric techniques. The aim is know whether the shape of each element studied differs between species of horses and also find some ecomorphological connection (form vs. substrate). The results prove the existence of three different groups related with the three species of horse registered in the localities studied; also, the existence of diagnostic elements for the differentiation of the three species of the late Pleistocene horse in Mexico. Based on the three diverse morphotypes is deduced that the species could live in different microhabitats and therefore be able to coexist in the same macrohabitat. Finally, the diversity of morphotypes suggests heterogeneous environments in the study localities., Agradecemos también al Proyecto CGL2016-79334-P de la FICYT del MEICOMP de España.

Trabajo presentado en el 40th World Congress of Vine and Wine: "Science and Economy, Culture and Education", celebrado en Sofía (Bulgaria), del 29 de mayo al 2 de junio (2017), Until the year 2008, the only ones white varieties sheltered by the AOC Rioja (Spain) were: ‘Viura’, ‘Garnacha blanca’ and ‘Malvasía’, representing ‘Viura’ practically the 100% of the total surface grown with white varieties and a 15% of the total vineyard surface in the AOC. In this context, since 1995 the viticultural and oenological behaviour of a new white variety, ‘Tempranillo blanco’, is studied with the objective of the increase the personality and typicity of the white wines from the AOC Rioja. ‘Tempranillo blanco' was obtained in 1988 from a natural mutation of the red cultivar 'Tempranillo' and was authorized by the AOC Rioja in 2008. The Vitivinicultural Research Service of the Regional Government of La Rioja set up a experimental vineyards net grown with ‘Tempranillo blanco’, located at eight different locations throughout the AOC Rioja, considering the influence of the environment diversity and the different growing conditions.

Active aging is one of the terms in the semantic network of aging well, together with others such as successful, productive, competent aging. All allude to the new paradigm in gerontology, where by aging is considered from a positive perspective. Most authors in the field agree active aging is a multidimensional concept, embracing health, physical and cognitive fitness, positive affect and control, social relationships and engagement. This paper describes Vital Aging, an individual active aging promotion program implemented through three modalities: Life, Multimedia, and e-Learning. The program was developed on the basis of extensive evidence about individual determinants of active aging. e different versions of Vital Aging are described, and four evaluation studies (both formative and summative) are reported. Formative evaluation reflected participants's satisfaction and expected changes; summative evaluations yielded some quite encouraging results using quasi-experimental designs: those who took part in the programs increased their physical exercise, signicantly improved their diet, reported better memory, had better emotional balance, and enjoyed more cultural, intellectual, affective, and social activities than they did before the course, thus increasing their social relationships. These results are discussed in the context of the common literature within the field and, also, taking into .account the limitations of the evaluations accomplished., Vital Aging Programs were sponsored by the Institute for Older Adults and Social Services (IMSERSO-UAM Agreements 1997-00), the Socrates Minerva Program of the European Commission (AGE-LL-C, 2001-03), and the UAM Santander Research Program for Latin America (PUM-e 2011).

5 páginas. Acceso a través de la página web http://www.energia2012.es [Acceso 09/03/2012], El aprovechamiento al máximo de cualquier subproducto generado durante un proceso industrial tiene que tener hoy día carácter prioritario. Una de las formas de reciclar estos materiales es buscar aplicaciones concretas de uso que sean factibles con las características de los mismos. Una de las ventajas que presenta el sector de la construcción es que, al margen de poder digerir ingentes cantidades de productos, admite una gama inmensa de calidades, lo que permite confeccionar una gran panorámica de materiales, cada uno adecuado para un uso concreto. La directiva 2008/98/CE del Parlamento Europeo y del Consejo establece un marco jurídico para el tratamiento de los residuos en la Unión Europea. Su objetivo es proteger el medio ambiente y la salud humana mediante la prevención de los efectos nocivos que suponen la producción y la gestión de residuos.

Trabajo presentado en el International RILEM Conference on Advances in Construction Materials Through Science and Engineering, celebrado en Hong Kong (China), del 5 al 7 de septiembre, The determination of free chloride concentration in the concrete inner pore solution is highly desirable for monitoring and control of corrosion of reinforcing steel in concrete. The nature of the above mentioned electrolyte implies that low chloride concentrations have to be measured in presence of high concentrations of the interfering hydroxide ion. The results of this work show that the interference of hydroxide ions upon the potentiometric response of a chloride ionic selective electrode, in alkaline solutions, similar to those present in the cement paste or concrete pore electrolytes, can be adequately modelized through the Nikolskii-Eisenman model. The limit of detection of the ISE, due to the abovementioned interference, varies with pH. For the studied media, and in the pH range from 12.3 to 13.7, chloride concentrations below 2•10-4 to 7•10-3 molal cannot be accurately determined by potentiometric measurements, due to the OH- interference. Taking into account these limits of detection, the free Cl- concentrations able to depassivate the steel, can be adequately determined by potentiometric measurements with calibrated ISEs in the expressed pore solutions of Portland cement concretes, without significant influence of OH- interference. Nevertheless, this effect can prevent the adequate measurement of low free Cl- concentrations, below the corresponding limit of detection value.

Trabajo presentado al XI Congreso Nacional de Materiales celebrado en Zaragoza del 23 al 25 de junio de 2010., En España, y más específicamente en Andalucía, la producción de energía a partir de la quema de biomasa presenta una actividad creciente, por lo que la caracterización de los residuos procedentes de esta combustión facilitaría su empleo futuro. En el presente trabajo se estudia la viabilidad técnica que presentan ciertos residuos (cenizas volantes y cenizas de fondo) procedentes de dicha combustión, para ser empleados en materiales de construcción, evaluando la composición química y mineralógica de estos residuos. Los resultados obtenidos muestran que los residuos analizados poseen propiedades aceptables para ser utilizados en la producción de materiales que tomen como base el cemento, si bien su calidad y tipo de aplicación depende de la procedencia del residuo., Los resultados que se exponen en el presente trabajo son fruto de los trabajos de investigación realizados en el marco del proyecto CLEAM CENIT, subvencionado por el CDTI dentro del programa CENIT. Dichos resultados son, pues, propiedad exclusiva de las empresas que promueven dicho proyecto y que constituyen la A.I.E. CLEAM-CENIT.

Bentonite and concrete are essential components in construction of a geological high level nuclear waste (HLNW) repository. Conventional Ordinary Portland Cement (OPC) used for concretes gives a pore water leachate with a pH as high as 13.5 in contact with ground water. This alkaline plume of leaching waters might perturb the engineered barrier system, which might include bentonite buffer, backfill material or the near-field host rock. The accepted solution to maintain the bentonite stability, which is controlled by the pH, is to develop cementitious materials with pore water pH around 11. Four lixiviation experiments representative of long-term interaction of solids and pore fluids at the concrete/bentonite interface were performed with two types of cement paste, Portland and calcium aluminate cement, before and after being carbonated under supercritical conditions, with granite water at 80 °C. The evolution of the pH indicates that the supercritical carbonation reduced the alkalinity of the cement pastes and calcite likely controls the equilibrium of Ca at the end of the experiments. The bentonite helps to buffer the alkalinity of concrete leachates through several reactions such as dissolution of montmorillonite and precipitation of secondary products as trioctahedral smectite, zeolites (gismondine), and presumably Mg hydroxides and amorphous gels. Carbonation may reduce propagation of the alkaline plume and enhance the barrier performance.

Comunicación presentada en las II Jornadas de Investigación en Construcción: "60 años de Informes de la Construcción", celebradas los pasados 22, 23 y 24 de mayo de 2008 en el Instituto "Eduardo Torroja" de Ciencias de la Construcción (IETCC-CSIC) de Madrid., [EN] The use of industrial waste with hydraulic or pozzolanic properties -silica fume, fly ash, blast furnace slag- as admixtures in cement based materials are focused to decrease the production costs, to improve micro-structural properties of the end product and also, in environmental aspects of converting waste materials into added value components., The use of olive biomass for cogeneration plants is an emerging activity in the energy field, which produces vast amounts of mineral waste (fly ash and slag). This paper studies the value of this industrial waste such as new components in the production of construction mortar. From application point of view, the object of the research focused on the incorporation of ashes in the mortar replacing part of the filler., [ES] El uso de residuos industriales con propiedades hidráulicas o puzolánicas -humo de sílice, cenizas volantes, escorias de altos hornos- como componente en materiales con base cemento está enfocado a disminuir los costes de producción, mejorar las propiedades micro-estructurales del producto final y también los aspectos medioambientales al transformar materiales residuales en componentes con valor añadido., El uso de biomasa del olivo en plantas de cogeneración es una actividad emergente en el campo de la energía, la cual produce grandes cantidades de residuos minerales (cenizas volantes y escorias). Este trabajo estudia la valorización de estos residuos industriales como nuevos componentes en la elaboración de morteros de construcción. Desde el punto de vista aplicativo, el objetivo de la investigación se centró en la incorporación de cenizas en el mortero sustituyendo parte del filler.

When concrete is exposed to the elements, its underlying microstructure can be attacked by a variety of aggressive agents; for example, rainwater and groundwater. The knowledge of concrete resistance to long term water aggression is necessary for predictions of their performance in different environments. This study aims to analyse the effects of leaching on the microstructure of Portland cement binders. Leaching of cement pastes was performed by an accelerated extraction leaching test that produces significant degradation and helps to achieve equilibrium or near-equilibrium conditions between the leachant medium and cement paste. FTIR spectroscopy, TG-DTA thermal analysis, low temperature nitrogen gas sorption, and geochemical modelling were used to characterize the microstructural changes produced in cement pastes at different equilibrium pHs reached during the leaching process.

The immobilization of wastes in cement suggests that cement compositions can be tailored in terms of pH, Eh and internal chemistry so as to maximize immobilization potential. This work presents some studies concerning the micro structure of calcium aluminate cement (CAC), and silica fume-calcium aluminate cement (SF-CAC) systems, and their resistance to the leaching by natural waters, with a view to assess them for possible uses, such us immobilization of toxic or radioactive wastes. The use of mineral additives such as silica fume, brings to the formation of aluminosilicate phases such as hydrogarnet Ca3Al2(SiO4)3-x(OH) 2x solid solution and gehlenite Ca2Al2SiO7.8H2O, which avoid the harmful so-called "conversion reaction" in CAC. Concretes based on calcium aluminate cement and calcium aluminate cement-silica fume, were submitted to a column leaching test based on water percolation, with a length of 2 years. Fourier-transform infrared spectroscopy (FTIR), and mercury intrusion porosimetry (MIP), were used to examine the bulk properties of the leached concretes. Scanning electron microscopy with energy dispersive X-rays analysis (SEM/EDX) was used to determine the composition of the pastes and morphology of the hydrates. © 2007 Elsevier B.V.

Cuando los materiales de la construcción son aplicados en el exterior, el agua de lluvia, el agua superficial o las aguas subterráneas, pueden ser responsables de que ocurran procesos de lixiviación o procesos de disolución y transporte de componentes de la fase sólida a una fase acuosa. En su interacción con las aguas, los materiales sufren una serie de transformaciones físicas y químicas; el ataque que se produce depende mucho del régimen hidrodinámico, del tipo de cemento y de la dosificación del hormigón. En el presente trabajo se comunican los resultados de varias investigaciones realizadas con financiación de la UE y de Enresa en el que se estudia el comportamiento frente a la lixiviación. Estos trabajos se han ampliado con financiación de Oficemen, para el estudio del comportamiento frente a la lixiviación de metales pesados y otros elementos, en cementos fabricados con combustibles tradicionales y cementos fabricados con combustibles alternativos.

[ES] Los materiales de la construcción pueden contener componentes tóxicos solubles. El proceso de disolución y transporte de estos componentes se denomina lixiviación. Cuando los materiales son aplicados en el exterior, el agua de lluvia, el agua superficial o las aguas subterráneas, pueden ser responsables de que ocurran procesos de lixiviación. Si la concentración de un componente tóxico lixiviado es muy elevada, se produce una amenaza potencial en el medioambiente. Los ensayos de lixiviación son indispensables para la caracterización de residuos y materiales de la construcción. En este sentido, en Europa, se está haciendo un gran esfuerzo por armonizar la legislación, como un paso lógico hacia una postura común europea en temas medioambientales., [EN] Building materials can contain soluble toxic components. The process of dissolution and transport of these components is named leaching. When the materials are applied in the outside, the rainwater, the surface water or the groundwaters, can be responsible of leaching processes. If the concentration of a leached toxic component is elevated, a potential threat in the environment takes place. The leaching tests are essential for the characterization of wastes and materials. In this sense, in Europe, a big effort is being made to harmonize the legislation, like a logical step towards an European common position in environmental subjects., Edición financiada por el Ministerio de Educación y Ciencia con cargo al "Plan Nacional de I+D+I 2004-2007".

It has been determined the thermal behaviour at high temperatures of an iron aluminum arsenate mineral first described in the location of La Serena Valley, Extremadura, Spain, which expands until 1173 K contracting later and softening at 1653 K and full melting at 1773 K. The DTA/TG experiment only detects some rearrangement with an endothermic at 1173 K due to the mica mixing. The mineral is a scorodite variety mixed with micaceous clay which has been found as aggregates of pyramidal crystals associated with quartz, wolframite, molibdenite, cassiterite and other secondary minerals in the pegmatite of the San Nicolas mine. The chemical composition, the physicochemical characteristics such as density and hardness, as well as the thermal behaviour has allowed to conclude that this mineral can be an Al-enriched scorodite (mansfieldite): (Fe, Al) AsO4·2H2O mixed with illite from the scorodite-mansfieldite series., Many thanks are due to J. M. Bassas, University of Barcelona, for carrying out the XRD experiments, as well as to A. Pérez Garrido from the University of Extremadura, Spain.

El comportamiento medioambiental de los cementos cuando son usados como materiales de la construcción, es de gran interés debido al aumento del uso de combustibles y materias primas alternativas en el proceso de fabricación del clinker. Los combustibles alternativos utilizados en los procesos de fabricación del cemento, pueden contener elementos no habituales en los combustibles tradicionales; por tanto, es necesario realizar un estudio del comportamiento frente a la lixiviación de los cementos obtenidos en dichos procesos, para evaluar la calidad medioambiental del producto final y garantizar su uso en la construcción. En este trabajo, el objetivo ha sido el estudio del comportamiento frente a la lixiviación de metales pesados y otros elementos, en cementos fabricados con combustibles tradicionales y cementos fabricados con combustibles alternativos

Los materiales arcillosos son un componente clave del almacenamiento profundo. Sus propiedades de retención, hinchamiento y muy baja permeabilidad los hacen idóneos para el sellado de estas instalaciones. Estos materiales interacionarán durante largos periodos de tiempo con el hormigón utilizado en la construcción del almacenamiento. En los últimos años, dos proyectos europeos, Ecoclay I y II, han abordado el estudio de estas interacciones bajo la coordinación de Enresa y Andra, y con la colaboración de investigadores de la Universidad Autónoma de Madrid y del csic
