    Description: In the last few years many efforts have been made by various groups to develop spark-protected micropattern gaseous detectors equipped with resistive electrodes instead of metallic ones. Great success has recently been achieved with resistive gas electron multipliers (GEMs), resistive micromesh gaseous structures and resistive Well/compteur a trou detectors. In this paper, we will focus on the development of a new family of spark-protected micropattern detectors: the 2D sensitive resistive microstrip counter and the resistive microhole and strip plate, which combines in one design a resistive GEM with a microstrip detector. These innovative detectors are manufactured on standard printed circuit boards by using a simple technology thus reducing the production cost. These novel detectors have several important advantages over other micropattern detectors and are unique for applications like the readout detectors for dual phase noble liquid time projection chambers and ring imaging Ch...

    Notes: Abstract Blood clotting parameters were measured in six patients with gynecologic tumors following i.v. administration of acetic acid-treated Salmonella minnesota R595 (Re), which has been previously demonstrated to enhance impaired immune functions in the same patients. Although these bacteria possess a more exposed lipid A at their surface which has the potential to stimulate the coagulative cascade, no evidence of plasma hypercoagulative state was detected. In fact, procoagulant activity generated by patients' mononuclear cells after Salmonella treatment was not significantly higher than that produced by patients' cells before treatment. Moreover, other haemostatic laboratory parameters were unaffected by in vivo treatment with bacteria.

    Description: On March 19, 1914 Giuseppe Mercalli, a seismologist and volcanologist, well-known around the world for the Intensity scale of earthquakes bearing his name, died tragically. A hundred years after, the Istituto Nazionale di Geofisica e Vulcanologia (INGV) has promoted a variety of activities and cultural events that will take place under the Patronage of the President of the Italian Republic within a year, the so called “Anno Mercalliano” (the Year of Mercalli). The opening ceremony took place in Naples, Italy, on March 19, 2014, in the Convitto Nazionale Vittorio Emanuele II. A scientific conference was held with the participation of experts from INGV and the university of Milano – Bicocca, and presentations of students. On that day the exhibition entitled “I luoghi di Mercalli” (Mercalli's places) was also inaugurated, at the presence of local authorities. The exhibition, organized by INGV, was realized in collaboration with the high school Vittorio Emanuele II, where Mercalli has been teaching for 19 years, and the Università degli Studi Suor Orsola Benincasa, where he was professor of natural sciences. A biographical and geographical description of the places where Mercalli operated introduces the exhibition, which is organized in sections: - Mercalli educator (he taught at high schools in Reggio Calabria and Naples); - Mercalli volcanologist (Mercalli studied Vesuvius volcanic activity for more than twenty years, he was a scientific witness of the Vesuvius 1906 eruption, and of the eruptions occurred at Vulcano (1888-90) and Stromboli (1891) islands. - Mercalli seismologist (Mercalli Intensity scale definition, based on his experience as witness of catastrophic earthquakes, such as Casamicciola in 1883 and Messina in 1908). Another section deals with the Vesuvius Observatory, directed by Mercalli between 1911 and 1914, and the description of the three active volcanoes of the Campania region (Vesuvius, Campi Flegrei and Ischia island), which have been the subject of studies by the well-known scientist. The exhibition is enriched by documents, manuscripts, photos and field notebooks of Mercalli. It is not intended to be only a celebratory exhibition; rather it is designed as a tool for dissemination of scientific culture and to raise awareness about seismic and volcanic hazards. In the exhibition path a continuous thread between the figure of Mercalli as a researcher and the role of an Earth Science researcher today is highlighted, pointing to the development of scientific knowledge in the past century. The goal is to improve the capability of learning from the disasters occurred in the past to implement preventive actions to safely deal with future events. The exhibition is travelling and will be provided on request to institutions and schools.

    Description: Vengono presentati i risultati preliminari della campagna oceanografica CAFE_07 - Leg 3, svoltasi nei Golfi di Napoli e Pozzuoli, nel Gennaio 2008, a bordo della Nave Oceanografica (N/O) URANIA del CNR. Lo scopo della campagna è stato l’acquisizione di profili sismici multicanale di elevata risoluzione dedicati allo studio stratigrafico-strutturale degli apparati vulcanici affioranti e sepolti nell’offshore Napoletano, ed il rilievo batimetrico di dettaglio dell’area sommersa. I dati raccolti sono consistiti in circa 800 km di profili sismici a riflessione multicanale di alta risoluzione, con acquisizione sismica simultanea da due sorgenti GI-gun operanti con potenza e frequenze differenti,mediante due cavi idrofonici. Durante la navigazione sono stati anche acquisiti profili sismici a riflessione monocanale di altissima risoluzione (sub-bottom CHIRP) e dati batimetrici mediante ecoscandaglio multifascio (multibeam). Il grid di acquisizione sismica multicanale è consistito in alcuni profili lunghi attraverso il Golfo di Napoli e da una fitta griglia di profili più corti, con interasse di circa 150 m, allo scopo di ottenere una copertura sismica quasi 3-D del Golfo di Pozzuoli. Questo set di dati costituisce una parte delle indagini di dettaglio richieste per la stesura di una proposta di perforazione del settore sommerso dei Campi Flegrei da sottomettere all’Integrated Ocean Drilling Program (IODP) ed è di supporto alla realizzazione di un progetto di perforazione profonda dei Campi Flegrei presentato all’International Continental Drilling Program (ICDP). We present the preliminary results of the oceanographic cruise CAFE_07 – Leg 3, conducted in the Napoli and Pozzuoli Bays in January 2008, on board of the Research Vessel (R/V) URANIA of the CNR. The aim of the cruise was the acquisition of high resolution multi-channel seismic profiles to understand the stratigraphic-structural setting of the Pozzuoli Bay area, with specific reference to the major offshore volcanic features, as well as the acquisition of bathymetric data on the seafloor morphology of the Bay. About 800 km of seismic profiles were acquired simultaneously by two acquisition systems, each characterized by different seismic source and streamer configuration, operating at different frequency ranges. Moreover shallow high resolution seismic reflection profiles (sub-bottom CHIRP) and multibeam echo-sounder bathymetry data have been recorded. The seismic grid consisted in a number of assistant profiles acquired over the Bay of Naples, along with a dense network of profiles with average distance of about 150 m between navigation routes, in order to obtain a quasi 3-D seismic coverage of the Pozzuoli Bay. This data set represents a part of the requirements for on-site detailed investigations (“site survey”) that are necessary for the development of an Integrated Ocean Drilling Program (IODP) proposal dedicated to the offshore drilling of the Campi Flegrei and is a relevant complement in the site survey of an ongoing project that has been submitted to the International Continental Drilling Program (ICDP).

    Description: Il 6 Aprile 2009 un terremoto di Ml=5.8 (Mw=6.2) ha colpito L’Aquila e la media valle dell’Aterno in Abruzzo. In questo lavoro presentiamo in maniera sintetica i rilievi geologici effettuati in campagna dal gruppo di lavoro EmerGeo a seguito della sequenza sismica aquilana. Le attività di rilevamento condotte sono consistite principalmente nella verifica, definizione e caratterizzazione delle deformazioni cosismiche superficiali osservate lungo le strutture tettoniche note in letteratura; sono stati inoltre rilevati e riportati altri effetti cosismici locali (fratture su asfalto, frane e scivolamenti) non direttamente collegati alla presenza di strutture tettoniche. In totale sono stati rilevati oltre 300 punti di osservazione su una porzione di territorio estesa circa 900 km2. L’analisi preliminare dei rilievi effettuati indica che le rotture osservate lungo la faglia di Paganica, per la continuità e le caratteristiche, rappresentano l’espressione superficiale della faglia responsabile dell’evento del 6 aprile 2009, e che le rotture lungo le faglie di Bazzano e di Monticchio-Fossa possono rappresentare l’espressione in superficie di una struttura antitetica riattivata durante l’evento.

    Description: The identification of the seismogenetic source of the Mw = 6.7, 1688 Sannio normal faulting earthquake is still a subject of scientific debate. This is due to several reasons comprising a) the possible incompleteness of the damage pattern, b) the difficult or not straightforward recognition of the induced surface deformation, c) the probable occurrence of blind or hidden faulting, and d) the low tectonic deformation rates and youthfulness of the source. According to the magnitude scaled with Wells and Coppersmith’s relationships the earthquake ruptured a 30 km-long, 16 km-wide normal fault. However, published works propose seismogenic sources for this earthquake slightly smaller than the expected from the empirical relationships alone. Similar results were obtained for other large historical events in central-southern Apennines. This may reflect either a routinely overestimation of the magnitude of earthquakes listed in the historical catalogue, or an underestimation of the geologically determined seismogenic sources. The goal of this paper is to collect original information for identifying the sismogenetic source of the 1688 earthquake, making use of seismological, geological and morphometrical data. In particular, the seismological data used in this study are relative both to the historical and recent seismic activity in the Sannio area, which in instrumental times was characterized by low energy seismic sequences (1990-92 and 1997, Md = 4.1). As regards the morphometrical analysis, we studied the Tammaro basin area (Sannio, Southern Apennines) for identifying the long term surface deformation induced by the seismogenetic fault of the 1688 earthquake. The reason of our choice is due to a) the hypothesis of the 1688 source location inside this basin, suggested by the seismogenetic source database DISS v. 3.1, b) the presence along the Tammaro river of young geomorphological features useful for revealing tectonic surface deformation, and c) clustering of recent seismic events inside this area along hypothetical boundaries of the master fault. Our analysis has been carried out by integrating the morphometrical data derived by processing of a very high resolution DTM (5x5 m pixel), with the geological and geomorphological data derived from photo-interpretation and field surveys in a GIS environment. The preliminary results have provided the following conclusions: a) the topographical parameters extracted from DTM show significant NW-SE lineaments on the right hand side of the valley of the Tammaro river; this evidence is further constrained by morphological analyses carried out both from orthophoto and from field surveys, that confirm the presence of a structural mountainside corresponding to the above lineaments; b) the low energy sequences, which were progressively activated, do not coincide with the main structural lineaments exposed at surface, but highlight the activity of buried structures likely acting as segment-boundaries and constraining the dimension of the 1688 seismogenetic source.
