Non-conventional water resources in coastal areas : a review on the use of reclaimed water
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
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 of the dissipative Kitaev chain are
found to be linked to the presence of Majorana edge master modes -- localized
eigenmodes of . 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
