Development of an active alkaline trap to determine acidic gas ratios in volcanic plumes: sampling technique and analytical methods

New insight into halogen release from experimental studies on BrO/Br ratios in volcanic plumes

High-spectral-resolution Fabry-Pérot interferometers overcome fundamental limitations of present volcanic gas remote sensing techniques

Remote sensing (RS) of volcanic gases has become a central tool for studying volcanic activity. For instance, ultraviolet (UV) skylight spectroscopy with grating spectrographs (GS) enables SO2 (and, under favourable conditions, BrO) quantification in volcanic plumes from autonomous platforms at safe distances. These measurements can serve volcanic monitoring and they cover all stages of volcanic activity in long measurement time series, which substantially contributes to the refinement of theories on volcanic degassing. Infrared (IR) remote sensing techniques are able to measure further volcanic gases (e.g., HF, HCl, CO2, CO). However, the employed Fourier transform spectrometers (FTSs) are…

Combined use of antifibrinolytics and activated prothrombin complex concentrate (aPCC) is not related to thromboembolic events in patients with acquired haemophilia A: data from FAIR Registry

Antifibrinolytics combined with aPCC are not routinely administered to patients with acquired hemophilia A due to increased thrombotic risk. This association normalizes clot stability, and improves the efficacy of therapy, but can increase the risk of severe side effects. Due to these premises it has always raised doubts and perplexities in the clinics. We now report the data of the "FEIBA® on acquired haemophilia A Italian Registry (FAIR Registry)", a retrospective-prospective study that included 56 patients. This is the first study that assessed the clinical response of the combination of aPCC and antifibrinolytic agents in patients with acquired haemophilia A. A total of 101 acute bleeds…

Passive degassing at Nyiragongo (D.R. Congo) and Etna (Italy) volcanoes: the chemical characterization of the emissions and assessment of their uptake of trace elements emissions on the local environment

Bromine chemistry of volcanic plumes

Volcanic gas studies are an established tool for volcanic monitoring and enhance the understanding of volcanic manifestations. The central question of the project, which we will introduce here, is whether the ratio between bromine monoxide (BrO) to sulphur dioxide (SO2) can potentially serve as indicator for volcanic activity. Both species have the advantage that they can be remotely measured by Differential Optical Absorption Spectroscopy (DOAS) at safe distances from the emission source. To answer the question above, it is of great importance to link the measurements of halogen oxides to the total emission flux of individual halogen species and to understand the influences of meteorologic…

Mappa di Comunità della Valle del Simeto

Questo libro è la storia di una collaborazione tra persone, legate fra loro dall'amore per un luogo, finalizzata alla "pratica" di una idea di sviluppo del territorio diversa da quella che viene loro imposta quotidianamente dalle strutture decisionali consolidate. Il luogo in questione e' una delle aree paesaggisticamente piu' pregiate della Sicilia, la Valle del Simeto, in corrispondenza del versante sud occidentale del vulcano Etna; l'idea di sviluppo che viene rigettata e' quella che, in passato, ha visto il materializzarsi di progetti di costruzione di impianti industriali altamente inquinanti lungo il corso del fiume Simeto; la "pratica" messa in campo dalla cittadinanza attiva simetin…
