    The “NEutrino Mediterranean Observatory - Submarine Network 1” (NEMO-SN1) seafloor observatory is located in the central Mediterranean Sea, Western Ionian Sea, off Eastern Sicily (Southern Italy) at 2100 m water depth, 25 km from the harbour of the city of Catania. It is a prototype of a cabled deep-sea multiparameter observatory and the first one operating with real-time data transmission in Europe since 2005. NEMO-SN1 is also the first-established node of the “European Multidisciplinary Seafloor and water column Observatory” (EMSO, http://www.emso-eu.org), one of the incoming European large-scale research infrastructures included in the Roadmap of the “European Strategy Forum on Research Infrastructures” (ESFRI, http://cordis.europa.eu/esfri/roadmap.htm) since 2006. EMSO will specifically address long-term monitoring of environmental processes related to Marine Ecosystems, Climate Change and Geo-hazards. NEMO-SN1 has been deployed and developed over the last decade thanks to Italian funding and to the EC project “European Seas Observatory NETwork - Network of Excellence” (ESONET-NoE, 2007-2011) that funded the “Listening to the Deep Ocean - Demonstration Mission” (LIDO-DM) and a technological interoperability test (http://www.esonet-emso.org/). NEMOSN1 is performing geophysical and environmental long-term monitoring by acquiring seismological, geomagnetic, gravimetric, accelerometric, physico-oceanographic, hydroacoustic, bio-acoustic measurements. Scientific objectives include studying seismic signals, tsunami generation and warnings, its hydroacoustic precursors, and ambient noise characterisation in terms of marine mammal sounds, environmental and anthropogenic sources. NEMO-SN1 is also an important test-site for the construction of the “Kilometre-Cube Underwater Neutrino Telescope” (KM3NeT, http://www.km3net.org/), another large-scale research infrastructure included in the ESFRI Roadmap based on a large volume neutrino telescope. The description of the observatory and its most recent implementations is presented. On 9th June, 2012 NEMO-SN1 was successfully deployed and is working in real-time.Published358 - 3741.8.

    Exclusive Photoproduction of the Cascade (Xi) Hyperons

    Full text link
    We report on the first measurement of exclusive Xi-(1321) hyperon photoproduction in gamma p --> K+ K+ Xi- for 3.2 < E(gamma) < 3.9 GeV. The final state is identified by the missing mass in p(gamma,K+ K+)X measured with the CLAS detector at Jefferson Laboratory. We have detected a significant number of the ground-state Xi-(1321)1/2+, and have estimated the total cross section for its production. We have also observed the first excited state Xi-(1530)3/2+. Photoproduction provides a copious source of Xi's. We discuss the possibilities of a search for the recently proposed Xi5-- and Xi5+ pentaquarks.Comment: submitted to Phys. Rev.

    Analisi di tre casi di suicidio con multiple lesioni da arma bianca: risultanze autoptiche e diagnostica differenziale tra omicidio e suicidio

    No full text
    International audienceÀ l’époque où écrit Beaumarchais, le théâtre, et notamment le drame, a pris le roman pour modèle et les deux genres se sont rapprochés. L’ensemble de la trilogie, avec ses paratextes, déborde largement des cadres temporels et spatiaux du théâtre classique, et donne à la vie des personnages une ampleur inusitée sur la scène (comme en témoigne, notamment, leur vieillissement), sans compromettre pour autant l’autonomie de chaque pièce, qui bénéficie d’éclairages multiples, ni diminuer la qualité dramaturgique de chacune d’entre elles

    Speciation of sulphur in asphaltenes and resins from Argentinian petroleum by using XANES spectroscopy

    No full text
    Argentinian crude oil samples from different origins have been processed to separate in the four fractions Saturates, Aromatics, Resins, and Asphaltenes (SARA). Asphaltene and resin fractions were extracted using n-pentane and n-heptane as precipitating solvents. Sulphur contents of the samples were determined by elemental analysis and X-ray Absorption Spectroscopy at the Sulphur K-edge was used to perform sulphur speciation for resin and asphaltene fractions. Reduce sulphur as sulphides, disulphides and thiophenes dominate the spectra of asphaltenes, resins I and crude oils samples. A higher abundance of sulfoxide forms were found in the resin II fraction. In addition, it was found that the asphaltenes are more enriched in aromatic sulphur (thiophene) when the n-heptane solvent is employed. From the sulphur speciation determination it was possible to incorporate different sulphur forms in the hypothetical average molecular structures for the Argentinian asphaltenes.Fil: Bava, Yanina Belén.
