PV Reconfiguration Systems: a Technical and Economic Study
2017
Dynamical electrical array reconfiguration strategies for grid-connected PV systems have been proposed as solution to improve energy production due to the mismatch effect of PV plants during partial shading conditions. Strategies are based on the use of dynamic connections between PV panels given by the employment of switches that allow for each panel the series, parallel or exclusion connections, physically changing the electrical connections between the related PV modules, consequentially modifying the layout of the plant. Usually the cost of the dynamic matrix is not taken into account. This novel work evaluates the economic advantages obtained by the use of reconfiguration strategies in…
Ecological Indicator Values of Europe (EIVE) 1.0: A Powerful Open-Access Tool for Vegetation Scientists
2016
International audience; Background: Ecological indicator values (EIVs) have a long tradition in vegetation ecological research in Europe. EIVs characterise the ecological optimum of species along major environmental gradients using ordinal scales. Calculating mean indicator values per plot is an effective way of bioindication. Following first systems in Russia and Central Europe, about two dozen EIV systems have been published for various parts of Europe.Aims: As there was no EIV system available at European scale that could be used for broad- scale analyses, e.g. in the context of the European Vegetation Archive (EVA), we develop such a system for the first time for the vascular plants of …
Rusia y la política energética de la Unión Europea
2010
A raíz de las irregularidades en el suministro de gas a la UE en 2006 y 2009 procedente de Rusia se ha vuelto a plantear el papel de este país en el ámbito energético-gasista europeo. En el diseño de un marco para la política energética europea se ha ido reconociendo un papel singular a Rusia, aunque una de las formas de incorporar a ese país en el ámbito energético europeo ha sido a través de su consideración como un riesgo geopolítico. Este enfoque se sustenta en el gran volumen de hidrocarburos que la UE adquiere en Rusia, dependencia que puede suponer que ese país pueda influir unilateralmente en el establecimiento de cantidades y precios, así como en las formas de reorganización del se…
Status of hormones and painkillers in wastewater effluents across several European states-considerations for the EU watch list concerning estradiols …
2016
Present technologies for wastewater treatment do not sufficiently address the increasing pollution situation of receiving water bodies, especially with the growing use of personal care products and pharmaceuticals (PPCP) in the private household and health sector. The relevance of addressing this problem of organic pollutants was taken into account by the Directive 2013/39/EU that introduced (i) the quality evaluation of aquatic compartments, (ii) the polluter pays principle, (iii) the need for innovative and affordable wastewater treatment technologies, and (iv) the identification of pollution causes including a list of principal compounds to be monitored. In addition, a watch list of 10 o…
Diagnóstico y políticas de promoción del emprendimiento en estudiantes
2015
La cada vez más saliente necesidad de contar con medidas tanto socio-económicas como educativas para desarrollar una cultura del emprendimiento hace imprescindible contar con una definición detallada del constructo, así como con una medida que permita disponer de una línea base del emprendimiento en estudiantes que facilitaría la evaluación de las intervenciones que desde el marco europeo y el gobierno estatal se propongan. El objetivo del estudio es proporcionar un conocimiento de las actitudes emprendedoras en el contexto educativo español, a partir del cual podrán realizarse implementaciones y evaluaciones de programas dedicados al fomento de la cultura y la educación emprendedora. 524 e…
Comparing analytical methods to detect SARS-CoV-2 in wastewater
2021
Wastewater based epidemiology (WBE) has emerged as a reliable strategy to assess the coronavirus disease 2019 (COVID-19) pandemic. Recent publications suggest that SARS-CoV-2 detection in wastewater is technically feasible; however, many different protocols are available and most of the methods applied have not been properly validated. To this end, different procedures to concentrate and extract inactivated SARS-CoV-2 and surrogates were initially evaluated. Urban wastewater seeded with gamma-irradiated SARS-CoV-2, porcine epidemic diarrhea virus (PEDV), and mengovirus (MgV) was used to test the concentration efficiency of an aluminum-based adsorption-precipitation method and a polyethylene…
Introduction of the circular economy within developing regions: A comparative analysis of advantages and opportunities for waste valorization
2018
The introduction of effective solid waste management strategies in developing countries should be considered for improving sustainability at global level. Many barriers should be overcome, concerning the introduction of environmental policies, effective investments, social inclusion and public awareness, which are significant issues in low-middle income countries. The Circular Economy could represent the answer for improving current solid waste management activities worldwide, since denote the principle of waste valorization and recycling for boosting developing economies. This paper is focused on this theme, analyzing main opportunities for improving the current state of solid waste manage…
Performance in the treatment of municipal waste: Are European Union member states so different?
2019
Abstract Efficient management and treatment of municipal waste is essential for achieving green growth. Recent studies have revealed convergence in European Union (EU) member states' performance in municipal waste treatment, particularly since the transposition of the 2008 European Waste Framework Directive into national laws. However, there are still notable differences between countries. In this paper, we calculate a composite indicator of performance in municipal waste treatment at the country-level. We also present an in-depth examination of differences in performance across EU member states. Our results show that the best performers—mainly high income Northern and Central European coun…
L’«infinito caso Contrada»: la Cassazione annulla con rinvio la decisione che ha riconosciuto la riparazione per ingiusta detenzione
2021
Il “caso Contrada” rappresenta uno degli esempi di diritto giurisprudenziale più dibattuti degli ultimi anni: terreno controverso in cui si sono affrontati il tema della ottemperanza diretta e indiretta delle decisioni europee, della tipologia degli strumenti interni di attuazione, della fluidità del giudicato a fronte delle violazioni dei diritti umani.
La planificación basada en competencias en los másteres oficiales: un reto para el profesorado universitario
2010
To focus the attention on competences means a radical change for the teaching design. It is one of the places where the most effective changes are expected. The research presented here tries to analyze the way that competences are used when describing official Master degrees. The competences of 87 Master degrees from 9 universities are analyzed. The results show that most Masters do not specify their competences. The most common ones refer to the knowledge application and that an enormous heterogeneity exists when classifying the types of competences. Desde la planificación docente, centrar la atención en las competencias supone un giro radical. Es uno de los elementos en los que se aspira …
