Remote sensing of volcanic CO2, HF, HCl, SO2, and BrO in the downwind plume of Mt. Etna
2017
Remote sensing of the gaseous composition of non-eruptive, passively degassing volcanic plumes can be a tool to gain insight into volcano interior processes. Here, we report on a field study in September 2015 that demonstrates the feasibility of remotely measuring the volcanic enhancements of carbon dioxide (CO2), hydrogen fluoride (HF), hydrogen chloride (HCl), sulfur dioxide (SO2), and bromine monoxide (BrO) in the downwind plume of Mt. Etna using portable and rugged spectroscopic instrumentation. To this end, we operated the Fourier transform spectrometer EM27/SUN for the shortwave-infrared (SWIR) spectral range together with a co-mounted UV spectrometer on a mobile platform in direct-su…
Preparation protocols for SEM visualization of charred fossil plants: the case of Weichselia reticulata pinnule anatomy
2021
The cosmopolite Mesozoic fern Weichselia reticulata presents many peculiarities in the anatomy of its stem as well as in the architecture of its leaves. Previous analyses of the ultrastructure of their pinnule laminas provided some insight on xeromorphic traits. In this work new protocols for the preparation of charred compression foliage specimens embedded in a limestone matrix for their observation under SEM are presented, which enhance the observation of different plant tissues. The preparation with HCl allows for the visualization of the whole lamina, from the upper to the lower epidermis, which had not been done to date. Additionally, collodion, latex, or wax coverings of the fossils b…

Debating Europe: Effects of the “Eurovision Debate” on EU Attitudes of Young German Voters and the Moderating Role Played by Political Involvement
2016
In the run-up to the elections to the European Parliament in 2014, EU citizens had the unprecedented opportunity to watch televised debates between the candidates running for president of the European Commission. The most important debate was the so-called "Eurovision debate", which was broadcasted in almost all EU member states. In this study we explore the responses of a sample of 110 young German voters, who watched this debate, to the candidates' messages and whether exposure to the debate caused a shift in the respondents' attitudes towards the EU. Combining data from a quasi-experiment, real-time response data, and data from a content analysis of the debate, we find that respondents' …

Desde los comienzos de su actividad investigadora, Alberto del Río se ha interesado por la literatura aragonesa medieval y de los siglos XVI y XVII, a la que ha seguido dedicando una parte de sus esfuerzos durante los últimos años. Este conocimiento le llevó en 1999 a publicar un estado de la cuestión en el que reflexionaba sobre las investigaciones más relevantes al hilo de un discurso, como siempre, impecablemente escrito. En él un nutrido abanico de referencias bibliográficas, cuidadosamente seleccionadas, proporcionaba un panorama de conjunto de la literatura de este periodo, aludiendo a otras realizaciones culturales coetáneas y justificando las causas que alentaron esos estudios. Desd…
Spazio, forma, materia, contesto. La lezione perpetua di Távora
2022
Fernando Távora è certamente l’iniziatore, il fondatore e l’ideatore di ciò che è riconosciuta come la Scuola di Architettura di Porto. Una Scuola espressione, oggi, di una palingenesi dell’architettura portoghese contemporanea e, forse, senza esagerazione, di un neo-rinascimento architettonico mondiale a cavallo tra il XX e il XXI secolo. Il magister per eccellenza, colui che traccia il primo solco della strada che sarà, in seguito, percorsa dai Discenti - Alvaro Siza Vieira ed Eduardo Souto de Moura - ma con la visione duplice e antitetica di chi sa che la meta si raggiunge volgendo costantemente lo sguardo in avanti e, nel contempo, indietro, al proprio vissuto formativo e al lascito del…
