Rediscovery of Hieracium nebrodense (Asteraceae), a little-known endemic of Sicily (Italy)

2016

Hieracium nebrodense Tineo ex Lojac., a little-known endemic of Sicily, has been rediscovered from the type locality after almost two centuries since its first and only collection made in 1830 in the Madonie Mountains (N Sicily). In line with the treatment in ‘Med-Checklist 2’, it is reclassified as a subspecies of H. schmidtii. A new combination is made and a detailed description and illustration are provided.

Il mutuo fondiario e la violazione del limite di importo massimo finanziabile: “scotismo” e onnipotenza delle etichette

2023

Il commento analizza una sentenza della Sezioni Unite e affronta il tema delle conseguenze civilistiche dell’erogazione di un mutuo fondiario in misura superiore rispetto al limite di importo massimo finanziabile, stabilito dalla Banca d’Italia in forza dell’art. 38, comma 2, T.U.B. La pronuncia si presenta di grande interesse perché correttamente esclude che il superamento di tale limite possa comportare la nullità del contratto di finanziamento, pervenendo a conclusioni in larga parte condivisibili tanto sui presupposti quanto sulle caratteristiche della nullità per violazione di norme imperative. Non altrettanto fondata si rivela, invece, l’ulteriore conclusione contraria al riconoscimen…

The Fate of Volcanogenic Major and Trace Elements emitted from the plume of Mount Etna

Signature of the 24th December 2018 eruption of Mt. Etna on the chemical composition of bulk deposition in the Siracusa area (Italy)

2020

Mt. Etna, in the eastern coast of Sicily (Italy), is one of the most active and most intensely monitored volcanoes of the planet. It is widely recognized as a big source of volcanic gases, such as CO2, SO2 and halogens, to the troposphere in the Mediterranean basin, and its gas emissions account for a significant percentage respect to the worldwide average volcanic budget. The SO2 flux from Mt. Etna’s plume has been routinely measured by the INGV since 1987. SO2 flux ranges between 600 to 25000 Mg/d; fluxes greater than 100000 Mg/d were prevalently measured during eruptive events. During eruptive periods, Etna’s emissions can be dispersed over long distances and cover wide areas of the Medi…

Mountain-building under extension

2013

A mechanism is presented which explains how intra-continental rifting can cause large topographic uplift. The effect is sufficient to account for the uplift of rift flanks and the very high and strongly localized uplift of the Rwenzori horst in the Western Branch of the East African Rift System. We propose that the uplift is generated by crustal bending, which is caused by a misfit of the lateral tensile stress between the upper and middle crust. The misfit is a function of different yield mechanisms when the upper crust breaks whereas the middle crust flows. Two independent numerical schemes confirm the suggested uplift mechanism. Both models—a 2 and 2.5 D elastoplastic lattice-particle mo…

Volcano seismicity and ground deformation unveil the gravity-driven magma discharge dynamics of a volcanic eruption.

2015

Effusive eruptions are explained as the mechanism by which volcanoes restore the equilibrium perturbed by magma rising in a chamber deep in the crust. Seismic, ground deformation and topographic measurements are compared with effusion rate during the 2007 Stromboli eruption, drawing an eruptive scenario that shifts our attention from the interior of the crust to the surface. The eruption is modelled as a gravity-driven drainage of magma stored in the volcanic edifice with a minor contribution of magma supplied at a steady rate from a deep reservoir. Here we show that the discharge rate can be predicted by the contraction of the volcano edifice and that the very-long-period seismicity migrat…

Trace element analysis in pre-solar stardust grains via full-field imaging XPS (Nano-ESCA)

2006

An acid-resistant, SiC-rich, residue from the Murchison meteorite was investigated by means of a novel imaging XPS instrument. The micrometer-sized grains were deposited on a Si wafer from an aqueous suspension. Energy filtered ESCA images have been taken in the kinetic energy range from the threshold up to about 400 eV for various photon energies. A lateral resolution of the order of 120 nm along with a high energy resolution in the range of 100 meV provides the basis for chemical trace element analysis with maximum sensitivity. Apart from major (Si, C) and minor (N, Mg, Al, Fe) elements, the energy filtered images and local microspectra revealed the presence of a variety of heavy trace el…
