    Non-conventional water resources in coastal areas : a review on the use of reclaimed water

    Get PDF
    In an era of increasing contest for limited water resources a wise joint management of conventional and non-conventional water resources must be considered. Water scarcity aggravates in coastal zones which are often characterised by high population density, intense economic activity and tourism meaning heavy seasonal water demands. The relationships between sea and land water can also compromise the quality of available freshwater. In this context, the use of non-conventional water increases the availability of water supplies. Non-conventional water resources of lower quality could be directed to meet several needs (like watering lawns, washing cars, flushing toilets and cooling systems, among others). Therefore, significantly more potable water would be available to meet human demand for safe water

    Dynamical signatures of topological order in the driven-dissipative Kitaev chain

    Get PDF
    We investigate the effects of dissipation and driving on topological order in superconducting nanowires. Rather than studying the non-equilibrium steady state, we propose a method to classify and detect dynamical signatures of topological order in open quantum systems. Bulk winding numbers for the Lindblad generator L^\hat{\mathcal{L}} of the dissipative Kitaev chain are found to be linked to the presence of Majorana edge master modes -- localized eigenmodes of L^\hat{\mathcal{L}}. Despite decaying in time, these modes provide dynamical fingerprints of the topological phases of the closed system, which are now separated by intermediate regions where winding numbers are ill-defined and the bulk-boundary correspondence breaks down. Combining these techniques with the Floquet formalism reveals higher winding numbers and different types of edge modes under periodic driving. Finally, we link the presence of edge modes to a steady state current.Comment: Submission to SciPost. 29 pages, 8 figure

    Posibilidades de la variabilidad genética de encinas y alcornoques en la conservación y recuperación de bosques amenazados por la "seca"

    Phytophthora cinnamomi Rands. (hongo patógeno del suelo) es el principal responsable del decaimiento de encinas y alcornoques en el Suroeste de la Península Ibérica. Este decaimiento es uno de los problemas ambientales más graves que amenaza la supervivencia y sostenibilidad, tanto ecológica como económica, de las formaciones de Quercus del sur peninsular. Este trabajo analiza la posibilidad del empleo de la variabilidad genética de la resistencia o tolerancia de los árboles al patógeno del suelo P. cinnamomi.____________________________________Phytophthora cinnamomi Rands is the main pathogen responsible for the holm and cork oaks decline in south-western Iberian Peninsula. This decay is one of the more serious environmental problems that threatens the survival and both ecological and economic sustainability of Quercus forests in southern Iberian Peninsula. The present work analyses the possibilities of use of genetic variability of resistance or tolerance of trees to the pathogen P. cinnamomi
