Crisis de deuda pública del estado español y la Unión Europea. ¿Causa o consecuencia?

In this research it is analyzed through empirical evidence the orthodox thesis about excessive public expenditure, generator of public deficit and debt, as cause of the current crisis in the peripherical european countries. After looking at the tendency of these variables within the last decade in Spain and the European Union it concludes with some reflections about the aforesaid thesis.En el presente estudio se analiza a través de la evidencia empírica la tesis ortodoxa del excesivo gasto público, generador de déficit y deuda pública, como causante de la actual crisis que viven los países de la periferia europea. Tras observar la tendencia de estas variables en la última década en el Estado español y la Unión Europea se concluye con unas reflexiones finales sobre susodicha tesis

Such areas are suitable for investigations of long-term biological effects of ocean acidification and effects of CO2 leakage from subsea carbon capture storage. Here, we show responses of benthic foraminifera to seawater pH gradients at 74-207m water depth. Living (rose Bengal stained) benthic foraminifera included Nonionella basispinata, Epistominella bradyana and Bulimina marginata. Studies on foraminifera at CO2 vents in the Mediterranean and off Papua New Guinea have shown dramatic long-term effects of acidified seawater. We found living calcareous benthic foraminifera in low pH conditions in the northern Gulf of California, although there was an impoverished species assemblage and evidence of post-mortem test dissolution

Tomographic imaging of ionospheric plasma bubbles based on GNSS and radio occultation measurements

Total electron content measurements given by the global navigation satellite system (GNSS) have successfully presented results to capture the signatures of equatorial plasma bubbles. In contrast, the correct reproduction of plasma depletions at electron density level is still a relevant challenge for ionospheric tomographic imaging. In this regard, this work shows the first results of a new tomographic reconstruction technique based on GNSS and radio-occultation data to map the vertical and horizontal distributions of ionospheric plasma bubbles in one of the most challenging conditions of the equatorial region. Twenty-three days from 2013 and 2014 with clear evidence of plasma bubble structures propagating through the Brazilian region were analyzed and compared with simultaneous observations of all-sky images in the 630.0 nm emission line of the atomic oxygen. The mean rate of success of the tomographic method was 37.1%, being more efficient near the magnetic equator, where the dimensions of the structures are larger. Despite some shortcomings of the reconstruction technique, mainly associated with ionospheric scintillations and the weak geometry of the ground-based GNSS receivers, both vertical and horizontal distributions were mapped over more than 30° in latitude, and have been detected in instances where the meteorological conditions disrupted the possibility of analyzing the OI 630 nm emissions. Therefore, the results revealed the proposed tomographic reconstruction as an efficient tool for mapping characteristics of the plasma bubble structures, which may have a special interest in Space Weather, Spatial Geodesy, and Telecommunications.Peer ReviewedPostprint (published version
