[EN]Happiness economics deals with self-reported subjective well-being, or life satisfaction, and its relationship to a wide variety of other variables. On the study of these other factors, this line of research has helped demonstrate that higher levels of environmental quality increase people’s subjective well-being. This paper focuses on analyzing the relationship between subjective well-being and air quality. On the one hand, the life satisfaction approach to environmental valuation is cautiously described, and on the other hand, the method is implemented in an empirical analysis that seeks to assess how an increase in the level of air pollution at a regional level affects individual-level subjective well-being in Europe. We use a dataset that merges the third wave of the European Social Survey (ESS) with a dataset that includes regional air pollution (including CO, PM10, NO2, SO2 and Benzene) and other regional variables. We find a robust negative impact for CO, a positive impact for SO2, and no conclusive evidence of any effect on subjective well-being for the remaining three pollutants.

Two high-frequency (HF) radar stations were installed on the coast of the south-eastern Bay of Biscay in 2009, providing high spatial and temporal resolution and large spatial coverage of currents in the area for the first time. This has made it possible to quantitatively assess the air-sea interaction patterns and timescales for the period 2009-2010. The analysis was conducted using the Barnett-Preisendorfer approach to canonical correlation analysis (CCA) of reanalysis surface winds and HF radar-derived surface currents. The CCA yields two canonical patterns: the first wind-current interaction pattern corresponds to the classical Ekman drift at the sea surface, whilst the second describes an anticyclonic/cyclonic surface circulation. The results obtained demonstrate that local winds play an important role in driving the upper water circulation. The wind-current interaction timescales are mainly related to diurnal breezes and synoptic variability. In particular, the breezes force diurnal currents in waters of the continental shelf and slope of the south-eastern Bay. It is concluded that the breezes may force diurnal currents over considerably wider areas than that covered by the HF radar, considering that the northern and southern continental shelves of the Bay exhibit stronger diurnal than annual wind amplitudes.

[ES]Hoy en día los vehículos usados en la extracción de sangre utilizan un motor de combustión interna, no solamente para sus desplazamientos, sino también para generar electricidad con la que poder utilizar todos los aparatos del interior. Como consecuencia, el autobús es una fuente importante de ruidos y contaminación, ya que el motor diesel está funcionando durante las largas paradas en las que se realiza dicha actividad. El objetivo del proyecto es diseñar un sistema innovador basado en pilas de combustible que sirva para alimentar todos los equipos y dispositivos, evitando el ruido, las vibraciones y los gases contaminantes. Para ello y en primer lugar, será necesario estimar el consumo total del autobús. Tras esto, también se tomarán una serie de decisiones con el fin de mejorar la eficiencia energética del autobús. Finalmente, se hará un diseño del sistema energético, el cual debe incluir una pila de combustible, junto con todos sus sistemas asociados, y todas las especificaciones.
