    Beschreibung: The persistent open-vent degassing of Mt. Etna is often punctuated by monthslong paroxysmal sequences characterized by episodes of violent Strombolian to lava fountaining activity. Understanding these gas-fueled transitions from quiescence to eruption requires routine measurement of gas fluxes. Here, we report SO2 flux measurements, obtained from a permanent UV camera system, collected over a two-year-long period spanning two paroxysmal sequences of Etna’s New South East Crater (NSEC) in December 2020/April 2021 and May/ October 2021. In both cases, SO2 flux increased from ≤ 3250 Mg/day during “ordinary” activity to ≥ 4200 Mg/day. We interpret these distinct SO2 degassing regimes in light of seismic and thermal observations and drawing on numerical simulations of sulfur degassing constrained by parental melt sulfur contents in Etna’s hawaiites. We find that initiation of a paroxysmal sequence results from an approximate doubling of the time-averaged rate of magma supply (and degassing) above the sulfur exsolution level (~150 MPa pressure), to 〉4m3/s. This corroborates recent models that argue for the triggering of paroxysmal sequences by escalating supply of volatile-rich magma to a reservoir ~3–4 km below the summit region. The non-stationary nature of magma flow and volcanic degassing we identify highlights the need for sustained surveillance to characterize long-term atmospheric budgets of volcanic volatiles

    Beschreibung: Roberto Pettorino was born in Naples on April 24, 1946. After graduating in Physics at the University of Naples Federico II in 1970, he later pursued research at Stanford's SLAC and Geneva's CERN. He was Full Professor of Theoretical Physics at the Faculty of Physical, Mathematical and Natural Sciences at Federico II University, Dean of the Faculty from 2007 to 2012, President of the University Assessment Team since October 2012. Since the first Open Archive was created by Paul Ginsparg in 1991 at the Los Alamos National Laboratory (LANL preprint archive, USA) for the elementary particle physics community, Roberto Pettorino was engaged in promoting Open Access. Since 2002, he had been delegated by the Rector of Naples Federico II for the libraries information services and member of the Scientific Technical Council of the Information Services Center; then he chaired the Permanent Commission for Libraries and Digital Resources. In 2002-2003 he promoted the development of the Digital Library of the University of Naples Federico II. Here are some contributions, collected to celebrate Roberto Pettorino's memory on April 8, 2013 when the Library Center was officially named after him.

    Beschreibung: This proceedings e-book contains papers presented at the national Symposium on “Electronic Books and the practices of scholarly research”, held in Naples, Italy, on 20 June 2003. The advent of new technologies, tools, and digital resources is changing how scholars conduct their work, keep updated in their field or fields of study, and think about research. Moving from the reconstruction of the market of scientific communication, copyright policies, and management of long-term conservation strategies, the published papers aim to discuss the ways in which scholarly practices have changed in the last decades, even since the end of the last century, in teaching and in research, in various disciplines like history, phisics and biomedical sciences.
