    The "Fondazione IRCCS Istituto Nazionale dei Tumori" ( National Tumour Institute) in Milan (Italy) offers mediation services aimed at restoring communication between patients and healthcare professionals, when their relationship has been altered by a conflict during the diagnosis or treatment process. A method derived from transformative mediation is used. The purpose of mediation is not to examine clinical aspects, nor to identify who is right and who is wrong. Individual sessions are often sufficient to reduce litigation.

    Italian center for Astronomical Archives (IA2, http://ia2.oats.inaf.it) is a national infrastructure project of the Italian National Institute for Astrophysics (Istituto Nazionale di AstroFisica, INAF) that provides services for the astronomical community. Besides data hosting for the Large Binocular Telescope (LBT) Corporation, the Galileo National Telescope (Telescopio Nazionale Galileo, TNG) Consortium and other telescopes and instruments, IA2 offers proprietary and public data access through user portals (both developed and mirrored) and deploys resources complying the Virtual Observatory (VO) standards. Archiving systems and web interfaces are developed to be extremely flexible about adding new instruments from other telescopes. VO resources publishing, along with data access portals, implements the International Virtual Observatory Alliance (IVOA) protocols providing astronomers with new ways of analyzing data. Given the large variety of data flavours and IVOA standards, the need for tools to easily accomplish data ingestion and data publishing arises. This paper describes the VO-Dance tool, that IA2 started developing to address VO resources publishing in a dynamical way from already existent database tables or views. The tool consists in a Java web application, potentially DBMS and platform independent, that stores internally the services' metadata and information, exposes restful endpoints to accept VO queries for these services and dynamically translates calls to these endpoints to SQL queries coherent with the published table or view. In response to the call VO-Dance translates back the database answer in a VO compliant way.

Il fatto che  il Convegno annuale di EURIG (il gruppo d'interesse europeo per RDA si tenga per la prima volta in Italia e a Firenze, non può che rivestire un particolare valore e interesse per la Biblioteca Nazionale Centrale di Firenze (BNCF per più motivi. La BNCF, infatti, nella sua duplice funzione di Agenzia bibliografica nazionale con la produzione della BNI (oggi aperta e gratuita, e di elaborazione degli strumenti nazionali aperti di indicizzazione semantica (il Nuovo Soggettario, contribuisce attivamente all'evoluzione dell'universo bibliografico e della scienza dell'informazione, all'interno del quale lo standard internazionale RDA rappresenta un punto di confronto imprescindibile.  Si può ricordare in proposito che la BNCF ha fatto parte (con Francesca Socci e Federica Paradisi, del Gruppo di lavoro tecnico dell'ICCU per la traduzione italiana di RDA, ed ha per prima presentato in sede in forma seminariale il Manuale RDA di Guerrini e Bianchini (4 ottobre 2016. Si può inoltre considerare che lo standard RDA è destinato a descrivere e dare accesso alle risorse in rete di qualsiasi tipologia e natura, fornendo strumenti di relazione fra le raccolte delle biblioteche degli archivi e dei musei: lo stesso terreno  in cui si svolge l'impegno attivo della BNCF all'interno del gruppo toscano Linguaggi del MAB (gruppo nazionale Musei-Archivi-Biblioteche, ed altrettanto avviene per quanto riguarda la tematica dell'Interoperabilità nel Web semantico.  Pur essendo nato in ambito bibliografico -a partire da FRBR- RDA si propone come standard universale di metadatazione non esclusivamente bibliografico, rispetto al quale anche i Codici nazionali di catalogazione possono porsi in modo dialettico e collaborativo per una reciproca evoluzione nell

    Full Text Available L'Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise è impegnato da anni nella ricerca e sperimentazione mirate ad approfondire la conoscenza delle malattie esotiche, cioè di quelle malattie che non sono presenti sul territorio nazionale. Per poter raggiungere tali obiettivi, è importante impegnarsi nella creazione di una rete di collaborazioni con Laboratori ed Enti di ricerca a livello nazionale ed internazionale. I rapporti che l'Istituto ha instaurato soprattutto con la Namibia e più di recente Botswana si stanno rivelando di notevole aiuto per la reciproca crescita tecnico-scientifica. L'Istituto coopera con i Servizi Veterinari della Namibia fornendo supporto tecnico-scientifico e nel 2005, ha allestito un proprio Laboratorio di Virologia, presso il Central Veterinary Laboratory di Windhoek, nel quale, personale dell'Istituto e namibiano, in unita' di intenti, condividono le competenze diagnostiche e la ricerca scientifica. Scopo del seguente lavoro è descrivere le attività svolte nell'ambito di questo rapporto di collaborazione.

  5. The optical counterpart of IGR J00291+5934 in quiescence

    2007-09-01

    Aims:The recent (December 2004) discovery of the sixth accretion-powered millisecond X-ray pulsar IGR J00291+5934 provides a very good chance to deepen our knowledge of such systems. Although these systems are well studied at high energies, poor informations are available for their optical/NIR counterparts during quiescence. Up to now, only for SAX J1808.4-3658, the first discovered system of this type, we have a secure multiband detection of its optical counterpart in quiescence. Among the seven known system IGR J00291+5934 is the one that resembles SAX J1808.4-3658 more closely. Methods: With the Italian 3.6 m TNG telescope, we have performed deep optical and NIR photometry of the field of IGR J00291+5934 during quiescence in order to look for the presence of a variable counterpart. Results: We present here the first multiband (VRIJH) detection of the optical and NIR counterpart of IGR J00291+5934 in quiescence as well as a deep upper limit in the K-band. We obtain an optical light curve that shows variability consistent with a sinusoidal modulation at the known 2.46 h orbital period and present evidence for a strongly irradiated companion.

    Context. High-resolution spectra of comets permit deriving the physical properties of the coma. In the optical range, relative production rates can be computed, and information about isotopic ratios and the origin of oxygen atoms can be obtained. Aims: The main objective of the work presented here was to obtain information about the chemical composition of comet C/2013 R1 (Lovejoy), a bright and long-period comet that passed perihelion (0.81 au) on 22 December 2013. Methods: We used the HARPS-North echelle spectrograph at the 3.5 m telescope TNG to obtain high-resolution spectra of comet C/2013 R1 (Lovejoy) in the optical range immediately after its perihelion passage during four consecutive nights in the period December 23 to 26, 2013. Results: Our results demonstrate the ability of HARPS-North to efficiently obtain cometary spectra. Very faint emission lines, such as those of 15NH2, have been detected, leading to a rough estimate of the 14N/15N ratio in NH2. The 12C/13C ratio was measured in the C2 lines and is equal to 80 ± 30. The oxygen lines were studied as well (green to red line intensity ratios and widths), confirming that H2O is the main parent molecule that photodissociates to produce oxygen atoms. This suggests that this comet has a high CO2 abundance. Relative production rates for C2 and NH2 were computed, but we found no significant deviation from a typical NH2/C2 ratio.

    We report preliminary results of a program to obtain high spectral- and temporal-resolution observations of the neutral helium triplet line at 1083.0 nm in transiting exoplanet systems. The principal objective of our program is to gain insight on the properties of active regions, analogous to solar plages, on late-type dwarfs by essentially using exoplanet transits as high spatial resolution probes of the stellar surface within the transit chord. The 1083 nm helium line is a particularly appropriate diagnostic of magnetized areas since it is weak in the quiet photosphere of solar-type stars but appears strongly in absorption in active regions. Therefore, during an exoplanet transit over the stellar surface, variations in its absorption equivalent width can arise that are functions of the intrinsic strength of the feature in the active region and the known relative size of the exoplanet. We utilized the Galileo Telescope and the GIANO-B near-IR echelle spectrograph to obtain 1083 nm spectra during transits in bright, well-known systems that include HD 189733, HD 209458, and HD 147506 (HAT-P-2). We also obtained simultaneous auxiliary data on the same telescope with the HARPS-N UV-Visible echelle spectrograph. We will present preliminary results from our analysis of the observed variability of the strength of the He I 1083 nm line during transits.Acknowledgements: Based on observations made with the Italian Telescopio Nazionale Galileo (TNG) operated on the island of La Palma by the Fundación Galileo Galilei of the INAF (Istituto Nazionale di Astrofisica) at the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias.

    Navarrini, Alessandro

    2017-11-01

    L'INAF-OA Cagliari (OACa) sta sviluppando un ricevitore criogenico a basso rumore basato su un mixer SSB (Single Side Band) a superconduttore SIS (Superconductor-Insulator-Superconductor) per la banda 3 mm. Il ricevitore, acquistato da IRAM, è stato fortemente modificato per essere adattato al fuoco Gregoriano di SRT (Sardinia Radio Telescope). Lo strumento è caratterizzato da una nuova criogenia a ciclo chiuso 4 K (per evitare l'uso di elio liquido in antenna), da un nuovo oscillatore locale (di tipo ALMA Banda 3) e da un nuovo sistema di controllo e di monitoraggio basato su schede Raspberry ed Arduino sviluppato ad OACa. Verranno presentati i recenti sviluppi sul ricevitore, inclusi i risultati preliminari della misura della temperatura di rumore, che raggiunge un valore pari a Trec=66 K alla frequenza di 86 GHz, nonostante la criogenia non sia ancora ottimizzata. L'INAF-OACa è coinvolto nel progetto AETHRA (Advanced European Technologies for Heterodyne Receivers for Astronomy) nel quadro del programma Radionet/Horizon2020 per il quale sta contribuendo al WP1 (Work Package 1). Lo scopo del WP1 è di sviluppare e costruire un dimostratore di un array di ricevitori a doppia polarizzazione per la banda 3 mm basato su amplificatori criogenici a basso rumore (LNA) in tecnologia a semiconduttore MMIC. Nell'ambito del WP1 l'OACa ha in carico il progetto di un OrthomodeTransducer (OMT) in guida d'onda o in tecnologia planare per la banda 72-116 GHz che sia integrabile con amplificatori MMICs ed adatto all'integrazione in un array da installare nel piano focale di un radiotelescopio. Verranno presentati i design preliminari degli OMT per AETHRA, che sono basati su prototipi sviluppati in passato da OACa.

    2006-01-01

    The fruitful collaboration between Italian Research Institutions, particularly Istituto Nazionale di Fisica Nucleare (INFN) and Istituto Nazionale di Geofisica e Vulcanologia (INGV) together with Marine Engineering Companies, led to the development of NEMO-SN-1, the first European cabled seafloor multiparameter observatory. This observatory, deployed at 2060 m w.d. about 12 miles off-shore the Eastern coasts of Sicily (Southern Italy), is in real-time acquisition since January 2005 and addressed to different set of measurements: geophysical and oceanographic. In particular the SN-1 seismological data are integrated in the INGV land-based national seismic network, and they arrive in real-time to the Operative Centre in Rome. In the European Commission (EC) European Seafloor Observatory NETwork (ESONET) project, in connection to the Global Monitoring for Environment and Security (GMES) action plan, the NEMO-SN-1 site has been proposed as an European key area, both for its intrinsic importance for geo-hazards and for the availability of infrastructure as a stepwise development in GMES program. Presently, NEMO-SN-1 is the only ESONET site operative. The paper gives a description of SN-1 observatory with examples of data

    1999-01-01

    At the Istituto Nazionale Neurologico C. Besta in Milano a network architecture has been developed to connect computers and diagnostic modalities, based on Intranet technology in order to allow the hospital to have an external access through the Internet. The Internet technology has become the "glue" that allows to link different computers and to develop applications able to work independently from the hardware/software platform. Using a PACS (Picture Archiving and Communication System) system integrated to the diagnostic modalities by means of the standardized DICOM image format, the digital radiological images can be transferred, displayed and processed on special visualization workstations all around the hospital. From the workstations the same images can be transferred in DICOM format to a teleconsulting workstation. In fact the hospital is involved in a national project for the remote connection between many Italian hospitals. This national network is linked to already developed regional networks like the Toscana MAN and the ATM Sirius Network. Some links are performed directly in ATM (155 Mbps), others are based on CDN (Direct Numerical Connection, 2Mbps), others are simply based on ISDN connections. The system allows to make it simpler and faster the already established daily exchange of radiological reports between the involved hospitals, especially from Istituto Nazionale Neurologico and Istituto Nazionale deiTumori. All the actions performed by the radiologist are translated by the software into "events" and replied to the remote workstation and vice-versa. In this way the radiologists can see each others, speak together and act in real time on a common "board" of diagnostic images, each one with his own pointer. The adopted technology is evolving on a system based on a web architecture and Java applications, useful for small clinical centers not endowed with expensive information systems. These centers will be able to get consulting performances by the

    The Solar photometer in X-rays (SphinX) experiment is scheduled for launch late summer 2008 on-board the Russian CORONAS-Photon satellite. SphinX will use three silicon PIN diode detectors with selected effective areas in order to record solar spectra in the X-ray energy range 0.3-15 keV with unprecedented temporal and medium energy resolution. High sensitivity and large dynamic range of the SphinX instrument will give for the first time possibility of observing solar soft X-ray variability from the weakest levels, ten times below present thresholds, to the largest X20+ flares. We present the results of the ground X-ray calibrations of the SphinX instrument performed at the X-ray Astronomy Calibration and Testing (XACT) facility of INAF-OAPA. The calibrations were essential for determination of SphinX detector energy resolution and efficiency. We describe the ground tests instrumental set-up, adopted measurement techniques and present results of the calibration data analysis.

The chemical and toxicological characteristics of emissions from two urban bus engines were studied: a diesel engine fueled with both diesel oil and bio diesel blend and an equivalent spark-ignition one fuelled with compressed natural gas, operating in steady-state conditions. Regulated and unregulated pollutants, such as carcinogenic polycyclic aromatic hydrocarbons and nitrated derivatives, carbonyl compounds and light aromatic hydrocarbons were quantified. Mutagenicity of the emissions was evaluated by the Salmonella typhimurium/mammalian microsome assay. The effect of the fuels under study on the size distribution of particulate matter was also evaluated. The impact of diesel-powered transport on urban air quality, and the potential benefits for human health deriving from the use of natural gas for public transport, are discussed.

Being diagnosed with cancer at this time can have important consequences on an individual's emotional and physical development, and adolescent and young adult cancer patients have particular medical and psychosocial needs. Patient–physician communications are important in any clinical relationship, but fundamental in the oncological sphere because their quality can affect the patient–physician relationship, the therapeutic alliance, and patient compliance. A major challenge when dealing with adolescent and young adult patients lies in striking the right balance between their need and right to understand their disease, treatment, and prognosis, and the need for them to remain hopeful and to protect their emotional sensitivity. We herein describe the activities of the Youth Project of the Istituto Nazionale Tumori in Milan, Italy in order to share a possible model of interaction with these special patients and the tactics our group has identified to help them communicate and share their thoughts. This model implies not only the involvement of a multidisciplinary team, including psychologists and spirituality experts, but also the constitution of dedicated creative activities to give patients the opportunity to express feelings they would otherwise never feel at ease putting into words. These efforts seek the goal to minimize the potentially

    The GINGERino ring laser gyroscope (RLG) is a new large observatory-class RLG located in Gran Sasso underground laboratory (LNGS), one national laboratory of the INFN (Istituto Nazionale di Fisica Nucleare). The GINGERino apparatus funded by INFN in the context of a larger project of fundamental physics is intended as a pathfinder instrument to reach the high sensitivity needed to observe general relativity effects; more details are found at the URL (https://web2.infn.it/GINGER/index.php/it/). The sensitivity reached by our instrument in the first year after the set up permitted us to acquire important seismological data of ground rotations during the transit of seismic waves generated by seisms at different epicentral distances. RLGs are in fact the best sensors for capturing the rotational motions associated with the transit of seismic waves, thanks to the optical measurement principle, these instruments are in fact insensitive to translations. Ground translations are recorded by two seismometers: a Nanometrics Trillium 240 s and Guralp CMG 3T 360 s, the first instrument is part of the national earthquake monitoring program of the Istituto Nazionale di Geofisica e Vulcanologia (INGV) and provides the ground translation data to be compared to the RLG rotational data. We report the waveforms and the seismological analysis of some seismic events recorded during our first year of activity inside the LNGS laboratory.

    Full Text Available Il tema della giustizia e della pena può essere riscontrato anche nella risoluzione del conflitto tra coniugi già a partire dal diritto romano arcaico. Si tratteggerà, quindi, l’evoluzione dell’istituto del divortium nel sistema giuridico romano a partire dalla sua nascita come risposta al ius vitae ac necis del marito sulla moglie, passando per il ripudio unilaterale e concludendosi con la dissoluzione del vincolo. L’analisi proseguirà attraverso uno sguardo sulla normativa di merito nell’età classica per poi soffermarsi sulla normativa del Tardo Impero che, incontrandosi con il Cristianesimo, fu soggetta a modificazioni in virtù delle spinte che la dottrina patristica sull’indissolubilità forniva. Si metterà in luce come il ius di cui si tratta, che vide la nascita del divortium quale risposta di un coniuge alle ingiustizie perpetrategli dall’altro, arrivò a doversi confrontare con la dottrina Cristiana che, nell’ambito matrimoniale, sostenendo la tutela del vincolo, riuscì a compiere un bilanciamento delle istanze sociali e religiose attraverso l’istituto della separazione come “pena misericordiosa”. La cuestión de la justicia y la pena puede ser individuada en la resolución de conflictos entre cónyuges a partir del derecho romano arcaico. Se delinea, por tanto, la evolución del instituto del divortium en el sistema jurídico romano desde su nacimiento como respuesta al ius vitae ac necis del marido sobre la mujer, pasando por el repudio unilateral y acabando con la disolución del vínculo. El análisis proseguirá considerando la normativa en la edad clásica hasta llegar a la normativa del Bajo Imperio que, encontrando el Cristianismo, sufrirá modificaciones a causa del empuje de la doctrina patrística sobre la indisolubilidad. Veremos como el ius en cuestión, que ve el nacimiento del divortium como respuesta de un cónyuge a las injusticias recibidas por parte del otro, tuvo que medirse con la doctrina

    The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is the Italian agency devoted to monitor in real time the seismicity on the Italian territory. The seismicity in Italy is of course variable in time and space, being also very much dependant on local noise conditions. Specifically, monitoring seismicity in an alluvial basin like the Po one is a challenge, due to consistent site effects induced by soft alluvial deposits and bad coupling with the deep bedrock (Steidl et al., 1996).

More recently, the combination of BRAF inhibitor dabrafenib with MEK inhibitor trametinib has shown improved progression-free survival, compared to dabrafenib monotherapy, in a Phase II study and has received approval by the US Food and Drug Administration. However, even when treated with the combination, most patients develop mechanisms of acquired resistance, and some of them do not achieve tumor regression at all, because of intrinsic resistance to therapy. Along with the development of BRAF inhibitors, immunotherapy made an important step forward: ipilimumab, an anti-CTLA-4 monoclonal antibody, was approved for the treatment of metastatic melanoma; anti-PD-1 agents achieved promising results in Phase I/II trials, and data from Phase III studies will be ready soon. The availability of such drugs, which are effective regardless of BRAF status, has made the therapeutic approach more complex, as first-line treatment with BRAF inhibitors may not be the best choice for all BRAF-mutated patients. The aim of this paper is to review the systemic therapeutic options

    In 2016 a collaboration agreement between CERN and Istituto Nazionale di Fisica Nucleare (INFN) through its Centro Nazionale Analisi Fotogrammi (CNAF, Bologna) was signed [1], which foresaw the purchase and installation of a cluster of 20 nodes with 32 cores each, connected with InfiniBand, at CNAF for the use of CERN members to develop parallelized codes as well as conduct massive simulation campaigns with the already available parallelized tools. As outlined in [1], after the installation and the set up of the first 12 nodes, the green light to proceed with the procurement and installation of the next 8 nodes can be given only after successfully passing an acceptance test based on two specific benchmark runs. This condition is necessary to consider the first batch of the cluster operational and complying with the desired performance specifications. In this brief note, we report the results of the above mentioned acceptance test.

    Reliable atomic and molecular data are of great importance for different applications in astrophysics, atmospheric physics, fusion, environmental sciences, combustion chemistry, and in industrial applications from plasmas and lasers to lighting. Currently, very important resources of such data are highly fragmented, presented in different, nonstandardized ways, available through a variety of highly specialized and often poorly documented interfaces, so that the full exploitation of all their scientific worth is limited, hindering research in many topics like e.g. the characterization of extrasolar planets, understanding the chemistry of our local solar system and of the wider universe, the study of the terrestrial atmosphere and quantification of climate change; the development of the fusion rersearch, etc. The Virtual Atomic and Molecular Data Centre (http://www.vamdc.eu, VAMDC) is an European Union funded FP7 project aiming to build a secure, documented, flexible and interoperable e-science environment-based interface to existing atomic and molecular data. It will also provide a forum for training potential users and dissemination of expertise worldwide.

The chemical and toxicological characteristics of emissions from two urban bus engines were studied: a diesel engine fueled with both diesel oil and bio diesel blend and an equivalent spark-ignition one fuelled with compressed natural gas, operating in steady-state conditions. Regulated and unregulated pollutants, such as carcinogenic polycyclic aromatic hydrocarbons and nitrated derivatives, carbonyl compounds and light aromatic hydrocarbons were quantified. Mutagenicity of the emissions was evaluated by the Salmonella typhimurium/mammalian microsome assay. The effect of the fuels under study on the size distribution of particulate matter was also evaluated. The impact of diesel-powered transport on urban air quality, and the potential benefits for human health deriving from the use of natural gas for public transport, are discussed [it

    The Centro di Ricerche Sismologiche (CRS, Seismological Research Centre) of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS, Italian National Institute for Oceanography and Experimental Geophysics) in Udine (Italy) after the strong earthquake of magnitude M=6.4 occurred in 1976 in the Italian Friuli-Venezia Giulia region, started to operate the Northeastern Italy Seismic Network: it currently consists of 19 very sensitive broad band and 17 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS CRS data centre in Udine. The southwestern edge of the OGS seismic network stands on the Po alluvial basin: earthquake localization and characterization in this area is affected by the presence of soft alluvial deposits. Following the ML=5.9 earthquake that struck the Emilia region around Ferrara in Northern Italy on May 20, 2012, a cooperation of Istituto Nazionale di Geofisica e Vulcanologia, OGS, the Comune di Ferrara and the University of Ferrara lead to the reinstallation of a previously existing very broad band (VBB) borehole seismic station in Ferrara and to the deployment of a temporary seismographic network consisting of eight portable seismological stations, to record the local earthquakes that occurred during the seismic sequence. The aim of the OGS intervention was on one hand to extend its real time seismic monitoring capabilities toward South-West, including Ferrara and its surroundings, and on the other hand to evaluate seismic site responses in the area. We will introduce details of the Ferrara VBB borehole station and the OGS temporary seismographic network configuration and installation. We will then illustrate the location capability performances, and finally we will shortly describe seismic site characterization with surface/borehole comparisons in terms of seismic noise, site amplification and resonance frequencies.

    Range spread-F (RSF) and occurrence of ''satellite'' traces prior to RSF onset were studied at the southern peak of the ionospheric equatorial anomaly (EA). Ionograms recorded in September 2007 at the new ionospheric station of Tucuman, Argentina (26.9 S, 294.6 E, dip latitude 15.5 S), by the Advanced Ionospheric Sounder (AIS) developed at the Istituto Nazionale di Geofisica e Vulcanologia (INGV), were considered. Satellite traces (STs) are confirmed to be a necessary precursor to the appearance of an RSF trace on the ionograms. Moreover, an analysis of isoheight contours of electron density seems to suggest a relationship between RSF occurrence and gravity wave (GW) propagation. (orig.)

    Since 1995, at the Istituto Nazionale Neurologico "Carlo Besta" in Milan (INNCB,) 401 deep brain electrodes were implanted to treat several drug-resistant neurological syndromes (Fig. 1). More than 200 patients are still available for follow-up and therapeutical considerations. In this paper our experience is reviewed and pioneered fields are highlighted. The reported series of patients extends the use of deep brain stimulation beyond the field of Parkinson's disease to new fields such as cluster headache, disruptive behaviour, SUNCt, epilepsy and tardive dystonia. The low complication rate, the reversibility of the procedure and the available image guided surgery tools will further increase the therapeutic applications of DBS. New therapeutical applications are expected for this functional scalpel.

    We report on the ATLAS and CMS joint research activity, which is aiming at the development of new, thin silicon pixel detectors for the Large Hadron Collider Phase-2 detector upgrades. This R&D is performed under special agreement between Istituto Nazionale di Fisica Nucleare and FBK foundation (Trento, Italy). New generations of 3D and planar pixel sensors with active edges are being developed in the R&D project, and will be fabricated at FBK. A first planar pixel batch, which was produced by the end of year 2014, will be described in this paper. First clean room measurement results on planar sensors obtained before and after neutron irradiation will be presented.

    Full Text Available Nel corso del presente articolo vengono descritte le premesse epistemologiche e le metodologie adottate dagli operatori del Servizio Intercultura dell’Istituto di Terapia Familiare di Firenze (ITFF nel lavoro con la popolazione migrante ed elencati gli interventi fatti nel territorio. Il Servizio Intercultura dell’ITFF si è interrogato in questi anni sul valore della cultura come porta d’ingresso nel rapporto con il migrante; nel chiedere loro di narrare aspetti della loro cultura condividiamo aspetti della nostra cultura. L’incontro con il malinteso, che come dice Jankelevitch «(… è un quasi niente» (Jankelevitch, 1987, p. 233, perché se fosse stato qualcosa di più ce ne saremmo accorti e se fosse qualcosa di meno non sarebbe significativo, ci permette di aprirci a un rapporto che cambia entrambi, operatore e migrante, nella relazione. È nella relazione e attraverso il racconto dell’evento migrazione e del ciclo di vita che si costruisce e si cerca un linguaggio comune per la descrizione e l’espressione del disagio. Il lavoro con i migranti deve fare i conti con le difficoltà legate all’impiego, alla casa, al permesso di soggiorno e non ultimo alla brevità di alcuni incontri, perché per alcuni la nostra città è solo una tappa di un percorso che continua alla ricerca di una sistemazione migliore. Nel territorio di Firenze sono stati messi a punto una serie di servizi: oltre alla clinica e a uno sportello di consulenza, ci si dedica alla formazione degli operatori che lavorano con i migranti. Esempi di queste attività sono: un progetto di peer tutoring in alcune scuole superiori, uno di formazione per le assistenti sociali al fine di proporre un protocollo più efficace di presa in carico dei migranti, una serie di focus group con dipendenti Asl all’interno del progetto “Mamma segreta” della regione Toscana; inoltre, la collaborazione con le associazioni presenti sul territorio ha permesso un contatto

  18. What does the InOMN mean to a national research institute like INAF?

    Boccato, C.

    2011-10-01

    I could not resist the temptation to use the slogan of InOMN 2011 for the title of this abstract; in addition to the description of our past experience in InOMN 2010, it has offered me the opportunity to share with you why a scientific research institute should promote this kind of event. The National Institute for Astrophysics is the main institute in Italy for research in this field. If, in one the hand, INAF is due to spread its scientific results to the public, then, on the other hand, it follows that an immediate link between public observation of the Moon, using little telescopes, and these results is not present. The reason why we should participate in InOMN can be summarized in one single word: humility. The Moon is the nearer celestial object that everybody can watch; it is the bridge between common people and astronomers. The first thing to do is see the sky, and then you can watch it. These first two steps are affordable to everyone without any additional help. In a third step you can observe it. Only at the very end of this process you can study the sky. These two last steps usually need a support from professionals. Observing the Moon with professionals narrows the gap between scientists and common people and opens the road to comprehension of astrophysical laws. Reaching more than ten thousand people from all over our country, as was the case for InOMN 2010, is not only important, but necessary for our institute; in this way, we raise the social consensus of our work, stimulate the younger generation to follow scientific study, and create a network with astronomy amateurs: all of which are essential to organizing these kinds of events. We used all possible channels to spread news about the event, including the Web and social networks (such as Facebook and Twitter), which we customized according to our language and cultural context. Using this approach, we covered all of Italy, with the additional help of astronomy amateurs and by investing a bit of

    Alanine-polyethylene solid state dosimeters were prepared at Istituto Superiore di Sanita (ISS) following the recipe proposed by National Institute of Standards and Technology (NIST) with the goal of testing its transferability. Dosimeters were prepared using 95% alanine and 5% polyethylene, by weight. They are rugged and of increased sensitivity, repeatability and reproducibility as respect to the ISS alanine-paraffin pellets. Reproducibility of about 1% was obtained at 10 Gy and at 3 Gy if one single pellet or a stack of five dosimeters were used, respectively.

  20. Optical identifications of celestial high energy sources with the Telescopio Nazionale Galileo

    2012-01-01

    To ascertain the nature of celestial high energy sources, it is crucial to identify their optical counterparts. However, the currently available astronomical public optical databases do not provide an adequate support for a systematic high energy sources identification work. In particular, the optical limiting magnitude represents a severe limitation since the deepest flux limits reached by X-ray surveys require of course similarly deeper optical catalogs to homogeneously sample the available parameter space. Nonetheless, dedicated spectroscopic campaigns are being carried out successfully with the Telescopio Nazionale Galileo (TNG), a 4-m class telescope. To set up a winning observational campaign, the first and most important step is to define a strong science case, as it will allow for selections of good targets for observations: the key is to increase the identification efficiency while keeping down the required telescope time. In this context, as the Principal Investigator, I will give an overview of the first spectroscopic campaign carried out at the TNG to identify Swift X-ray serendipitous sources, and I will show the valuable results achieved with only one night of observations. As a second example, I will review the strategy for the northern-sky classification of candidate blazars associated to unidentified Fermi γ-ray sources, and I will show the results coming from the related observational campaign at TNG I have been involved during the last two years.

    The objective of the study is to develop new food packaging nanomaterials based on biopolymers (PLA) to be used in prepackaged foods intended for radiation. The processing conditions were optimized, and the properties of the systems before irradiation were studied. From these studies, the following conclusions were drawn: 1) The final properties of polymer nanocomposites depend on their structure and morphology, and 2) Improved properties can be achieved only if a good dispersion and distribution are realized in the polymer nanomaterials. The team at Istituto di Chimica e Tecnologia dei Polimeri, Consiglio Nazionale delle Ricerhe (ICTP/CNR) participated in the IAEA CRP on “Application of Radiation Processing Technology in the Development of Advanced Packaging Materials for Food Products”.

    A detailed theoretical derivation of the cross sections of e+e- → e+e- and e+e- → μ + μ - around the J/ψ resonance is reported. The resonance and interference parts of the cross sections, related to J/ψ resonance parameters, are calculated. Higher-order corrections for vacuum polarization and initial-state radiation are considered. An arbitrary upper limit of radiative correction integration is involved. Full and simplified versions of analytic formulae are given with precision at the level of 0.1% and 0.2%, respectively. Moreover, the results obtained in the paper can be applied to the case of the ψ(3686) resonance.

    At the Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali del Sud (INFN-LNS) the beam commissioning of the high intensity Proton Source for the European Spallation Source (PS-ESS) started in November 2016. Beam stability at high current intensity is one of the most important parameter for the first steps of the ongoing commissioning. Promising results were obtained since the first source start with a 6 mm diameter extraction hole. The increase of the extraction hole to 8 mm allowed improving PS-ESS performances and obtaining the values required by the ESS accelerator. In this work, extracted beam current characteristics together with Doppler shift and emittance measurements are presented, as well as the description of the next phases before the installation at ESS in Lund.

Gli autori costruiscono un modello dell'economia italiana per analizzare l'impatto di queste due variabili correlate. Si è concluso che i disavanzi pubblici del passato hanno prodotto una riduzione proporzionale del risparmio nazionale . A partire dai primi anni 1960 risparmi nazionali sono diminuiti di quasi 9 punti percentuali , di cui 3,6 punti percentuali possono essere contabilizzati da un aumento del 4 per cento nel deficit del governo .

    Full Text Available The essay aims at showing the development of the critical thought about Prometheus Bound that underlied the staging of this tragedy at the Teatro Greco of Siracusa during the spring of 2012. The performance was directed by the author of these pages for the Istituto nazionale del dramma antico (premiere: Siracusa, 11th May. In the framework of a hermeneutic paradigm based on the ‘critically’ untimely nature of the classic, the staging of Prometheus here discussed wanted to inquire the role of sight in the orchestration of this tragedy, as well as to account for the way time is treated in the text. In the light of this approach, Prometheus looks like a cruel portrait of a world in a state of crisis, suspended between two disasters (one has just ended, the other is looming ominously on the horizon; from its remote distance, such a world gives us an image both lucid and alienated of our present.Il saggio si propone di restituire il percorso di riflessione critica intorno al Prometeo incatenato che nella primavera del 2012 ha sostanziato il processo di messa in scena della tragedia presso il teatro greco di Siracusa, curata dall’autore di queste pagine per conto dell’Istituto nazionale del dramma antico (debutto: Siracusa, 11 maggio. Entro un paradigma ermeneutico fondato sul principio dell’inattualità ‘critica’ del classico, l’allestimento del Prometeo di cui qui si riferisce punta a indagare il ruolo svolto dallo sguardo nell’orchestrazione della tragedia, così come a render ragione del trattamento cui la funzione tempo è sottoposta nell’opera. Sulla base di un simile approccio, il Prometeo appare così come un crudele ritratto di un mondo in crisi sospeso tra due catastrofi (l’una appena trascorsa, l’altra minacciosamente incombente all’orizzonte; un mondo che dalla sua remota distanza ci consegna un’immagine ad un tempo lucida e straniata del nostro presente.

Real time data exchange agreements in place with other Italian, Slovenian, Austrian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time, which makes the OGS the reference institute for seismic monitoring of North-eastern Italy. The south-western edge of the OGS seismic network (Fig. 1) stands on the Po alluvial basin: earthquake localization and characterization in this area is affected by the presence of soft alluvial deposits. OGS ha already experience in running a local seismic network in high noise conditions making use of borehole installations in the case of the micro-seismicity monitoring of a local gas storage site for a private company. Following the ML = 5.9 earthquake that struck the Emilia region around Ferrara in Northern Italy on 20 May 2012 at 02:03:53 UTC, a cooperation of Istituto Nazionale di Geofisica e Vulcanologia, OGS, the Comune di Ferrara and the University of Ferrara lead to the reinstallation of a previously existing very broad band (VBB) borehole seismic station in Ferrara.

    Third ventriculostomy has become an increasing popular procedure for the treatment of hydrocephalus of different aetiologies. Between october 1997 and october 1998, 17 patients (12 females, 5 males; 12-82 year-old; mean age 43) underwent image-assisted endoscopic third ventriculostomy for hydrocephalus at the Istituto Nazionale Neurologico "C.Besta" of Milano. There was no mortality and no long term morbidity. Neuronavigation has been found useful in selecting the safest trajectory to the target avoiding any traction on the foramen of Monro related structures and allowing the necessary mobility for fine adjustments under visual and "tactile" control when choosing the safest point to perform the stoma. According to our experience neuro-endoscopy and neuronavigation seems to be complementary in reaching easy, safe and successful results in the treatment of hydrocephalus of different origins.

    Ansani, Fabrizio

    This article examines the technological development of artillery production in Florence during the last two decades of the fifteenth century, before and after the assimilation of the most efficient French ordnance into Italian warfare. The study starts from the notes, drawings, accounts, and guns produced by Bonaccorso di Vettorio Ghiberti (1451-1516), the heir of the foundry of his illustrious ancestor Lorenzo di Cione (1378-1455). Data have been collected from the historical archives of the Istituto degli Innocenti, from the Biblioteca Nazionale Centrale of Florence, and from the Florentine State Archive. This article demonstrates the existence of a lively and reactive war-related industry in Renaissance Italy, which was aware of new ideas and new techniques. The article highlights, moreover, the leading role of public demand in fostering military innovations.

    NEXT (Nationwide Evaluation of X-ray Trends) is a program for the evaluation of patient exposure in X-ray diagnostic tests. The program is aimed at reducing patient exposure by pin-pointing poor radiological techniques and improving them. CNEN (Comitato Nazionale per l'Energia Nucleare) and ISS (Istituto Superiore di Sanita) have been developing such a program in Italy since 1976. Up to now two regional administrations applied the method and regional operators collected the needed data in all the medical institutions in their areas. The results show a wide spread of values for all the parameters studied in the 12 X-ray projections selected. Gonad dose and skin entrance exposure were found to be spread over a range up to about two orders of magnitude. (H.K.)

    Given the practical impossibility of obtaining new precision Rh-0.5at%Fe resistance thermometers in recent years, the possible re-starting of the production of such thermometers in Yunnan (China) was explored by Istituto Nazionale di Ricerca Metrologica (INRIM). Ten prototypes of the new production were made available in early 2006. The paper reports the preliminary data from the testing performed to date on these prototypes at National Institute of Metrology (NIM) and Instytut Niskich Temperatur i Badan Strukturalnych (INTiBS). Although a problem with the alloy composition was detected, the reproducibility results on thermal cycling are very encouraging. Resistance-temperature ( R- T) characteristics below 30 K, though not identical with those of similar thermometers formerly available from Tinsley and VNIIFTRI, are still suitable for accurate metrology.

    The muon tomography technique, based on multiple Coulomb scattering of cosmic ray muons, has been proposed as a tool to detect the presence of high density objects inside closed volumes. In this paper a new and innovative method is presented to handle the density fluctuations (noise) of reconstructed images, a well known problem of this technique. The effectiveness of our method is evaluated using experimental data obtained with a muon tomography prototype located at the Legnaro National Laboratories (LNL) of the Istituto Nazionale di Fisica Nucleare (INFN). The results reported in this paper, obtained with real cosmic ray data, show that with appropriate image filtering and muon momentum classification, the muon tomography technique can detect high density materials, such as lead, albeit surrounded by light or medium density material, in short times. A comparison with algorithms published in literature is also presented

    Environmental topics are today at the centre of the public attention, but people mostly does not have cultural tools for an adequate knowledge. The radioactivity, in particular, is generally misunderstood and this had negatively influence debate about the energy. To fill this gap science subjects need to be study in school with a more efficient approach. Many efforts have spent to obtain this goal: in this framework the Envirad project was developed with the aim to make students of high schools of Campania Region (south-Italy) able to practice experimental method involving directly them in a real environmental physics experiment [1]. The aim of this project, developed by the grant of the Istituto Nazionale di Fisica Nucleare, is that the effective experimental activity is the best way to provide for an adequate scientific background.

    Full Text Available Qual è la funzione del Servizio Nazionale di Valutazione formativa degli istituti scolastici? A cosa servono davvero le prove Invalsi? Le critiche che spesso vengono mosse a queste prove sono veramente fondate? Come può la valutazione dell’offerta formativa scolastica costituire davvero un agente di miglioramento? Il presente articolo intende fornire alcune risposte a queste domande, partendo dalle istanze che hanno ispirato l’autonomia scolastica e offrendo spunti per un utilizzo non fazioso della valutazione. La valutazione può essere davvero agente di cambiamento a patto che: i sia attribuito ai dati il corretto significato; ii la scuola sia in grado di comprendere i potenziali suggerimenti che la valutazione può dare e si apra al cambiamento positivo. La valutazione applicata ad una “scuola che si difende” non può che provocare inutili esiti di facciata. La valutazione applicata ad una “scuola che apprende” può davvero aiutarla ad esplicare appieno tutte le proprie potenzialità.

    At the Department of Physics of the Universita degli Studi di Milano in collaboration with the Medical Physics Unit and the Radiotherapy Unit of the Fondazione IRCCS Istituto Nazionale dei Tumori di Milano the research of a dosimetric technique based on Fricke gel layers and optical analysis in under study. In fact, Fricke gel layer dosimeters (FGLD) have various advantages such as the tissue-equivalence for photons in the clinical energy interval, the possibility to obtain the spatial information about continuous dose distribution and not only a point dose distribution as it is for example in the case of ionization chambers, TLD or diodes and the possibility to obtain the information about 3D dose distributions. In this work, specific applications of FGLD to absolute dosimetry in radiotherapy have been studied, i.e. in-phantom measurements of complex intensity modulated radiation therapy fields (IMRT) and complex brachytherapy fields.

    The versatile ion source is an off-resonance microwave discharge ion source which produces a slightly overdense plasma at 2.45 GHz of pumping wave frequency extracting more than 60 mA proton beams and 50 mA He+ beams. DAEδALUS and IsoDAR experiments require high intensities for H2+ beams to be accelerated by high power cyclotrons for neutrinos generation. In order to fulfill the new requirements, a new plasma chamber and injection system has been designed and manufactured for increasing the H2+ beam intensity. In this paper the studies for the increasing of the H2+/p ratio and for the design of the new plasma chamber and injection system will be shown and discussed together with the experimental tests carried out at Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali del Sud (INFN-LNS) and at Best Cyclotron Systems test-bench in Vancouver, Canada.

    The fabrication and characterization of a charged particle imaging system composed of a tracker and a residual range detector (RRD) is described. The tracker is composed of four layers of scintillating fibers (SciFi), 500 μm side square section, arranged to form two planes orthogonal to each other. The fibers are coupled to two Multi-Pixel Photon Counter (MPPC) arrays by means of a channel reduction system patented by the Istituto Nazionale di Fisica Nucleare (INFN) (Presti, 2015) [1]. Sixty parallel layers of the same fibers used in the tracker compose the RRD. The various layers are optically coupled to a MPPC array by means of wavelength shifting (WLS) fibers. The sensitive area of the two detectors is 9×9 cm2. The results of the measurements, acquired by the prototypes with CATANA (Cirrone, 2008) [2] proton beam, and a comparison with the simulations of the detectors are presented.

    Full Text Available Adolescents and young adults (AYA with cancer form a particular group of patients with unique characteristics, who inhabit a so-called no man’s land between pediatric and adult services. In the last ten years, the scientific oncology community has started to pay attention to these patients, implementing dedicated programs. A standardized model of care directed towards patients in this age range has yet to be developed and neither the pediatric nor the adult oncologic systems perfectly fit these patients’ needs. The Youth Project of the Istituto Nazionale Tumori in Milan, dedicated to adolescents and young adults with pediatric-type solid tumors, can be seen as a model of care for AYA patients, with its heterogeneous multidisciplinary staff and close cooperation with adult medical oncologists and surgeons. Further progress in the care of AYA cancer patients is still needed to improve their outcomes.

The amendments concern the reorganisation of the CNEN into a new body, the National Commission for Research and Development of Nuclear and Alternative Energy Sources (ENEA), which in addition to nuclear energy, will also be responsible for R and D in alternative energy sources, with the exception of hydrocarbons. In order to facilitate the ENEA's tasks, the new Act gives it a great degree of flexibility and administrative autonomy. The staff of ENEA will also be granted a legal status closely related to that of the industrial sector. It will also retain temporarily the previous CNEN's regulatory tasks in nuclear safety and radiation protection. (NEA) [fr

    In 1999 INFN (Istituto Nazionale di Fisica Nucleare) ordered to ANSALDO the manufacturing of 16 double pancakes for the ATLAS BARREL TOROID. In July 2001 four Double Pancakes have already been completed and shipped to the integration site. In this paper the main aspects of the manufacturing of the largest superconducting coils ever built (5*25 m) are described. The main phases of the manufacturing procedure are reviewed starting from the conductor preparation to the VPI impregnation, including references to the materials used as well as to the relevant customer's requirements. In particular the special winding form and the winding technique are treated. For each phase the most critical aspects and the relevant solutions are pointed out. Particular details about the technical solutions adopted for the impregnation and curing of the Double Pancake, which could not be performed inside an autoclave due to the huge dimension of the coil itself, are reported. Finally the methods used for the dimensional and electri...

    2013-01-01

    Deep brain stimulation (DBS) of the posterior hypothalamus (pHyp) has been reported as an effective treatment for primary, drug-refractory and chronic cluster headache (CCH). We here describe the use of such a procedure for the treatment of secondary CCH due to a neoplasm affecting the soft tissues of the right hemiface. A 27-year-old man affected by infiltrating angiomyolipoma of the right hemiface who subsequently developed drug refractory homolateral CCH underwent DBS of the right pHyp region at the Fondazione IRCCS Istituto Nazionale Neurologico Carlo Besta. After surgery, the patient presented a significant reduction in frequency of pain bouts. However, because of a subsequent infection, the entire system was removed. After re-implantation of the system, successful outcome was observed at 2 years follow-up. This brief report shows the feasibility of pHyp DBS in secondary drug-refractory CCH syndromes; future reports are needed in order to confirm our positive result.

    The systems 32S+Ca,4840 and 32S+48Ti at 17.7 MeV/nucleon were investigated with the setup general array for fragment identification and for emitted light particles in dissipative collisions (GARFIELD) plus ring counter (RCo) at Laboratori Nazionali di Legnaro (LNL) of Istituto Nazionale di Fisica Nucleare (INFN). Fusion evaporation (FE), fusion fission (FF), and deep inelastic (DIC) events were identified, also through the comparison with the prediction of a transport model (stochastic mean field, SMF), coupled to GEMINI++ as an afterburner. This work mainly deals with the study of isospin transport phenomena in DIC events. In particular, the isospin diffusion is highlighted by comparing the average isotopic content of the quasiprojectile (QP) remnants observed when the target is the N =Z nucleus 40Ca and when it is the neutron-rich 48Ca. Also, the d /p and t /p ratios for particles forward emitted with respect to the QP were found to increase with increasing N /Z of the target.

    SPES (Selective Production of Exotic Species) is a facility under construction at INFN-LNL (Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali di Legnaro), aimed to produce intense neutron-rich radioactive ion beams (RIBs). These will be obtained using the ISOL (Isotope Separation On-Line) method, bombarding a uranium carbide target with a proton beam of 40MeV energy and currents up to 200μA. The target configuration was designed to obtain a high number of fissions, up to 1013 per second, low power deposition and fast release of the produced isotopes. The exotic isotopes generated in the target are ionized, mass separated and re-accelerated by the ALPI superconducting LINAC at energies of 10AMeV and higher, for masses in the region of A = 130 amu , with an expected rate on the secondary target up to 109 particles per second. In this work, recent results on the R&D activities regarding the SPES RIB production target-ion source system are reported.

    Pierluigi Campana begins his 3-year tenure as LHCb spokesperson this June. As the new voice for the collaboration, Campana will lead the experiment through what should prove to be a very exciting phase.   Pierluigi Campana, from the Istituto Nazionale di Fisica Nucleare in Frascati, has been with the collaboration since 2000 and was heavily involved in the construction of the muon chamber of the LHCb detector. He replaces Andrei Golutvin, from Imperial College London and Russia’s Institute for Theoretical and Experimental Physics. “Leading such a large collaboration is not an easy task,” says Campana. While he will rely heavily upon the work of his predecessor, he plans on leaving his own mark on the position: “One of the main goals of my job will be to enhance the spirit of collaboration between the different institutes within our experiment.” LHCb plays a key role in the search for new physics. The experiment is conducting a very precise search...

    2015-04-01

    This work presents the design of a low-noise front-end implementing a novel active signal compression technique. This feature can be exploited in the design of analog readout channels for application to the next generation free electron laser (FEL) experiments. The readout architecture includes the low-noise charge sensitive amplifier (CSA) with dynamic signal compression, a time variant shaper used to process the signal at the preamplifier output and a 10-bit successive approximation register (SAR) analog-to-digital converter (ADC). The channel will be operated in such a way to cope with the high frame rate (exceeding 1 MHz) foreseen for future XFEL machines. The choice of a 65 nm CMOS technology has been made in order to include all the building blocks in the target pixel pitch of 100 μm. This work has been carried out in the frame of the PixFEL Project funded by the Istituto Nazionale di Fisica Nucleare (INFN), Italy.

    Full Text Available The SPES project at INFN-LNL (Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali di Legnaro is focused on the production of radioactive ion beams. The core of the SPES facility is constituted by the target, which will be irradiated with a 40 MeV, 200 µA proton beam in order to produce radioactive species. In order to efficiently produce and release isotopes, the material constituting the target should be able to work under extreme conditions (high vacuum and temperatures up to 2000 °C. Both neutron-rich and proton-rich isotopes will be produced; in the first case, carbon dispersed uranium carbide (UCx will be used as a target, whereas to produce p-rich isotopes, several types of targets will have to be irradiated. The synthesis and characterization of different types of material will be reported. Moreover, the results of irradiation and isotopes release tests on different uranium carbide target prototypes will be discussed.

    The design update of the European Spallation Source (ESS) accelerator is almost complete and the construction of the prototype of the microwave discharge ion source able to provide a proton beam current larger than 70 mA to the 3.6 MeV Radio Frequency Quadrupole (RFQ) started. The source named PS-ESS (Proton Source for ESS) was designed with a flexible magnetic system and an extraction system able to merge conservative solutions with significant advances. The ESS injector has taken advantage of recent theoretical updates and new plasma diagnostics tools developed at INFN-LNS (Laboratori Nazionali del Sud, Istituto Nazionale di Fisica Nucleare). The design strategy considers the PS-ESS and the low energy beam transport line as a whole, where the proton beam behaves like an almost neutralized non-thermalized plasma. Innovative solutions have been used as hereinafter described. Thermo-mechanical optimization has been performed to withstand the chopped beam and the misaligned focused beam over the RFQ input collimator; the results are reported here.

    1999-06-01

    Full Text Available We present the results of studies of seismicity in the Reggio Emilia area (Northern Italy. The Istituto Nazionale di Geofisica instrumental earthquake catalogue (1975-1996 reported about three moderate-size earthquakes with M ³ 4.5 that occurred in this area (November 1983, May 1987, October 1996. The RTL prognostic parameter proposed by Sobolev and Tyupkin (1996a was used for analysis. This parameter is designed in such a way that a seismic quiescence produces negative anomaly of the RTL parameter in comparison to its perennial background level and an activation of seismicity initiates the growth of its value. The RTL prognostic parameter indicates that all three earthquakes are preceded by activation of the seismicity. The interval between the commencement of the activation identified by RTL parameter and the event itself was about one year for the 1987 and 1996 earthquakes, and about three months for the 1983 earthquake.

    Full Text Available In the middle of 1989, the INGV (Italian Istituto Nazionale di Geofisica e Vulcanologia installed in Central Italy a network of magnetic stations in order to investigate possible relationship of the local magnetic field with earthquakes occurrences. Actually the network consists of four stations, where the total magnetic field intensity data are being collected using proton precession magnetometers. Here we are report on the actual state and the future developments of the network. In the frame of the MEM (Magnetic and Electric fields Monitoring Project, new stations will be added to the network by the end of 2007. The results of the test campaigns carried out in the sites chosen to widen the network are also discussed. Moreover, the 2006 complete data set of the network is also reported. Concerning the data analysis, a new approach is also discussed that takes into account the inductive effects on the local geomagnetic field by means of the inter-station transfer functions time variations analysis.

  12. Double-crystal analyser system for the PRISMA spectrometer: test of a prototype

    International Nuclear Information System (INIS)

    Petrillo, C.; Sacchetti, F.; Steigenberger, U.

    1993-11-01

    A prototype of a double-analyser system has been tested at the ISIS pulsed neutron source in order to determine the performance of such an analysing device in the low energy transfer region. The performance of such a system has been found satisfactory in terms of reflectivity and energy resolution as well as alignment procedures. Based on our test results we propose the construction of a second arm for the PRISMA (PRogetto deol'Istituto di Struttura della MAteria del Consiglio Nazionale delle Ricerche) spectrometer at ISIS. This new arm would enable us to perform measurements with much improved energy resolution and to extend the wavevector transfer range to much smaller values thus improving the instrument performance significantly for magnetic scattering experiments. The new, modular approach of the upgrade will also strengthen the flexibility of the instrument and open up the opportunity for further instrumental developments, for example the introduction of a polarization option.

    Full Text Available Fra le diverse tipologie di motivi ornamentali, gli alfabeti figurati costituiscono un vero e proprio genere a se stante, che attinge al repertorio iconografico del proprio tempo e lo riflette in composizioni dotate di grande fascino e originalità. Per la quantità, la qualità e l’eterogeneità degli esemplari custoditi, il Gabinetto Disegni e Stampe della Pinacoteca Nazionale di Bologna costituisce un caso più unico che raro in Italia, vantando alfabeti figurati che abbracciano ampi confini geografici e cronologici, spaziando dal tardo gotico al XIX secolo. Dopo una breve introduzione sulle vicende collezionistiche di un nucleo grafico così insolito e particolare, l’articolo si concentra su alcuni esemplari di alfabeti figurati del Cinquecento di area transalpina. Partendo dall’alfabeto dei bambini di Hans Weiditz (1521, costruito rispettando le più rigorose regole geometriche, codificate nei coevi trattati rinascimentali, ma anche riflesso del rinato gusto per i fregi all’antica con putti, si passa agli alfabeti di Peter Flötner (1534 e di Jost Amman (1567, dove le lettere sono integralmente costituite da corpi umani, forzati in complicate posture, talvolta persino licenziose. Questi esemplari rappresentano degli interessanti esperimenti calligrafici, dove l’uomo diviene concretamente l’unità di misura dei caratteri dell’alfabeto.

    The potential advantage of using 111 In-antifibrin ( 111 In-AF) monoclonal antibody for the diagnosis of deep venous thrombosis (DVT) was studied in 44 patients with suspected DVT (27 underwent heparin therapy before 111 In-AF injection). All patients had contrast venography (considered as the gold standard) and 111 In-AF scintigraphy within 24 hr. Two to 3 mCi of 111 In-AF were injected intravenously, and planar scintigraphy of the limbs was recorded within 10 min (17 times), 3 hr (44 times), and 18 hr (39 times). Indium-111-AF images were then interpreted without knowledge of the results of the other examinations. The DVT diagnostic accuracy of 111 In-AF was greater when interpretation was based on images recorded at different time periods after injection. Indium-111-AF sensitivity for diagnosis of DVT was 85% (29/34) and was not apparently decreased by heparin therapy. None of the 10 patients with negative contrast venography had a positive 111 In-AF scan. The results demonstrate the importance of recording serial images and the excellent accuracy of 111 In-AF for diagnosing DVT

    In May 1960, the Farmitalia CEO Dr. Bertini and the director of the Istituto Nazionale dei Tumori of Milan Prof. Bucalossi (talent scout and city's Mayor) signed a research agreement for the discovery and development up to clinical trials of new natural antitumor agents. This agreement can be considered as a pioneering and fruitful example of a translational discovery program with relevant transatlantic connections. Owing to an eclectic Streptomyces, found near Castel del Monte (Apulia), and to the skilled and motivated participants of both institutions, a new natural antitumor drug, daunomycin, was ready for clinical trials within 3 years. Patent interference by the Farmitalia French partner was overcome by the good quality of the Italian drug and by the cooperation between Prof. Di Marco, director of the Istituto Ricerche Farmitalia Research Laboratories for Microbiology and Chemotherapy, and Prof. Karnofsky, head of the Sloan-Kettering Cancer Institute of New York, leading to the first transatlantic clinical trials. The search for daunomycin's sister anthracyclines led to the discovery and development of adriamycin, one of the best drugs born in Milan. This was the second act prologue of the history of Italian antitumor discovery and clinical oncology, which started in July 1969 when Prof. Di Marco sent Prof. Bonadonna the first vials of adriamycin (doxorubicin) to be tested in clinical trials. This article reviews the Milan scene in the 1960s, a city admired and noted for the outstanding scientific achievements of its private and public institutions in drugs and industrial product discovery.

    2017-06-01

    In this paper, a distributed optimal control problem is studied for a diffuse interface model of tumor growth which was proposed by Hawkins-Daruud et al in Hawkins-Daruud et al (2011 Int. J. Numer. Math. Biomed. Eng. 28 3-24). The model consists of a Cahn-Hilliard equation for the tumor cell fraction φ coupled to a reaction-diffusion equation for a function σ representing the nutrient-rich extracellular water volume fraction. The distributed control u monitors as a right-hand side of the equation for σ and can be interpreted as a nutrient supply or a medication, while the cost function, which is of standard tracking type, is meant to keep the tumor cell fraction under control during the evolution. We show that the control-to-state operator is Fréchet differentiable between appropriate Banach spaces and derive the first-order necessary optimality conditions in terms of a variational inequality involving the adjoint state variables.

Cardiac function was evaluated by transthoracic echocardiography measurements before and after treatment for 2 or 7 days, by using a Vevo 2100 high-resolution imaging system. After echocardiography, mice were euthanized, and hearts were processed for histological evaluations, such as cardiac fibrosis, apoptosis, capillary density, and inflammatory response.Results: Trastuzumab-related cardiotoxicity was detected early by 2D strain imaging. Radial strain was reduced after 2 days in mice treated with trastuzumab alone (21.2%±8.0% vs 40.5%±4.8% sham; P<0.01. Similarly, trastuzumab was found to induce apoptosis, capillary density reduction, and inflammatory response in cardiac tissue after 2 days of treatment, in a fashion similar to doxorubicin.

    This work is a part of the MAGIC-5 (Medical Applications on a Grid Infrastructure Connection) experiment of the Italian INFN (Istituto Nazionale di Fisica Nucleare). A simple CAD (Computer-Assisted Detection) system for juxta-pleural lung nodules in CT images is presented, with the purpose of comparing different 2D concavity-patching techniques and assessing the respective efficiency in locating nodules. After a short introduction on the motivation, and a review of some CAD systems for lung nodules already published by the MAGIC-5 Collaboration, the paper describes the main lines of this particular approach, giving preliminary results and comments. In our procedure, candidate nodules are identified by patching lung border concavities in a hierarchical multiscale framework. Once located, they are fed to an artificial neural network for false positive reduction. The system has a modular structure that easily allows the insertion of arbitrary border-smoothing functions for concavity detection and nodule searching. In this paper the {alpha}-hull and morphological closing are compared, proving the higher sensitivity of the former, which also appears computationally less heavy.

    Intrathecal baclofen is presently the most effective treatment for diffuse spasticity whatever the cause. The fact that both spasticity is always accompanied by a degree of muscle weakness and that any antispastic treatment causes a decrease in muscle strength indicate that major attention must be paid in treating spasticity in ambulant patients. Methods.  We present here a retrospective study, approved by the insitutional ethics committee, of 22 ambulant spastic patients, selected as homogeneous for disease and disease duration, who were treated with intrathecal baclofen at the Istituto Nazionale Neurologico "C.Besta" in Milan. These patients were followed-up for to 15 years of treatment and their clinical assessment was enriched by the evaluation of their functional independence measurement (FIM) before and during treatment. Results.  There was improvement in quality of life as measured by the FIM scale; however, an increase in the patient's motor performance could not be detected. Conclusion.  Although we did not show any improvement in muscle performance, intrathecal baclofen did improve daily quality of life, even in spastic patients who were able to walk.

    Deep brain stimulation (DBS) extends the treatment of some severe neurological diseases beyond pharmacological and conservative therapy. Our experience extends the field of DBS beyond the treatment of Parkinson disease and dystonia, including several other diseases such as cluster headache and disruptive behavior. Since 1993, at the Istituto Nazionale Neurologico "Carlo Besta" in Milan, 580 deep brain electrodes were implanted in 332 patients. The DBS targets include Stn, GPi, Voa, Vop, Vim, CM-pf, pHyp, cZi, Nacc, IC, PPN, and Brodmann areas 24 and 25. Three hundred patients are still available for follow-up and therapeutic considerations. DBS gave a new therapeutic chance to these patients affected by severe neurological diseases and in some cases controlled life-threatening pathological conditions, which would otherwise result in the death of the patient such as in status dystonicus, status epilepticus and post-stroke hemiballismus. The balance of DBS in severe neurological disease is strongly positive even if further investigations and studies are needed to search for new applications and refine the selection criteria for the actual indications.

    Full Text Available The seismic period which occurred in a portion of Guidonia Montecelio and Tivoli territory, two towns situated about twenty kilometres NE of Rome, affected four areas with a high density of population: Guidonia, Collefiorito, Villalba and Bagni di Tivoli. Even though the events had a very low magnitude (less than 3.0, local phenomena, like rumbles and strong vibrations of the ground, frightened inhabitants also because some months before (January 26, 2001 in a village named Marcellina situated a few kilometres away from Guidonia, a large sinkhole (600 m had appeared without fore signals. The «Istituto Nazionale di Geofisica e Vulcanologia» (INGV installed some digital stations that monitored the seismic phenomena. This paper has the aim to process all the information acquired during the period, both from the micro and macro seismic point of view, in order to explain the phenomenology that involved the area. The synergy of the two methodologies lead us to the conclusion that two different seismotectonic structures originated the events, one in an anti-apenninic direction, the other in a N-S direction.

    This document was prepared by the community that is active in Italy, within INFN (Istituto Nazionale di Fisica Nucleare), in the field of ultra-relativistic heavy-ion collisions. The experimental study of the phase diagram of strongly-interacting matter and of the Quark-Gluon Plasma (QGP) deconfined state will proceed, in the next 10-15 years, along two directions: the high-energy regime at RHIC and at the LHC, and the low-energy regime at FAIR, NICA, SPS and RHIC. The Italian community is strongly involved in the present and future programme of the ALICE experiment, the upgrade of which will open, in the 2020s, a new phase of high-precision characterisation of the QGP properties at the LHC. As a complement of this main activity, there is a growing interest in a possible future experiment at the SPS, which would target the search for the onset of deconfinement using dimuon measurements. On a longer timescale, the community looks with interest at the ongoing studies and discussions on a possible fixed-target p...

    We provide a database of the coseismic geological surface effects following the Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one of the strongest seismic events to occur in Europe in the past thirty years, causing complex surface ruptures over an area of >400 km 2 . The database originated from the collaboration of several European teams (Open EMERGEO Working Group; about 130 researchers) coordinated by the Istituto Nazionale di Geofisica e Vulcanologia. The observations were collected by performing detailed field surveys in the epicentral region in order to describe the geometry and kinematics of surface faulting, and subsequently of landslides and other secondary coseismic effects. The resulting database consists of homogeneous georeferenced records identifying 7323 observation points, each of which contains 18 numeric and string fields of relevant information. This database will impact future earthquake studies focused on modelling of the seismic processes in active extensional settings, updating probabilistic estimates of slip distribution, and assessing the hazard of surface faulting.

    1994-06-01

    Full Text Available Significant variations in the absolute value of the geomagnetic field intensity related to tectonic events, as earthquakes and volcanic eruptions, have been observed in several cases. To detect such a tectonomagnetic effect related to seismic activity, a seismomagnetic network was installed by the Istituto Nazionale di Geofisica (ING in the Abruzzi region (CentraI Italy, in July 1989. This area is being uplifting since the Pliocene. A logistic compromise between geophysical requirements and the electrified railway system tracks distribution led to the installation of five total magnetic field intensity data acquisition sites. From July 1989 to September 1992 geomagnetic intensity data were simultaneously recorded at all stations and compared to that recorded at the L'Aquila Observatory, located in the same area. A variation of about 10 nT in the absolute level of the geomagnetic field was measured at two stations located on the eastern side of the network. We suggest that the detected magnetic anomaly could resuIt from aseismic-changes in crustal stress during this time.

    1996-05-01

    A search for production of the supersymmetric (SUSY) particles squark (tildeq) and gluino (tildeg) was performed using 19 pb-1 p overline p collision data collected with the CDF detector during the 1992-93 Tevatron run at Fermilab. We have selected events with high missing transverse energy (ET) and multiple jets. High /ET is expected in most SUSY events since the lightest SUSY particle (LSP) is assumed to be stable and non-interacting. The principal backgrounds to this search are W + jets, Z + jets, and QCD multijet production, where some of the leptons or jets are unobserved. *We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

    We give preliminary results of a search for tbart production in p\\overlinep collisions at √s = 1.8 TeV using data collected at the Collider Detector at Fermilab (CDF). The search is performed using the decay channel tbart arrow six jets. Kinematic cuts are applied to reduce the QCD backgrounds. We search for events with both b-quark jets identified by looking for displaced secondary vertices. Contributions from all non-top sources of double b-tags are calculated. We also determine the invariant mass of the candidate t and bart quarks. The results include an analysis of 110 pb-1 of data collected from 1992-95. * Supported by the U.S. Department of Energy and National Science Foundation; the Italian Istituto Nazionale di Fisica Nucleare; the Ministry of Education, Science and Culture of Japan; the Natural Sciences and Engineering Research Council of Canada; the National Science Council of the Republic of China; the Alexander von Humboldt-Stiftung and the A.

    We present results of a search for charged Higgs production from pbarp collisions at √s=1.8 TeV at Fermilab's Tevatron collider using the CDF detector. An expanded Higgs sector containing charged Higgs bosons is a persistent feature of candidate theories to replace the Standard Model. The minimal supersymmetric extention of the Standard Model, for example, predicts that the dominant decay mode of the top quark is tarrow H+barrow τ+ν b for large values of tanβ. We use the hadronic decays of the tau lepton in this channel to set a new limit on charged Higgs production. *We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

    The case study of the Office of External Activities in Cape Coast, Ghana has turned out to be a successful story in promoting research and capacity building of young scientists. The total involvement of many organizations show how laudable the idea has been. This centre has come to serve as a place to solve scientific problems as well as problems of national interest. It is foreseen that its activities can be a means to congregate African scientists to solve common problems. I think the bold step taken by OEA and some organs of ICTP, Trieste, Italy, Lund Institute of Technology, Sweden and Istituto Nazionale di Ottica Applicata, Firenze, Italy has helped up and coming African scientists to come face to face with the challenges of Laser research. Such projects seem feasible and sustainable since experts in these areas can serve as contact persons in Africa to undertake common research using optical techniques. This project has made it possible to explore various areas in optics that can be used to solve proble...

  19. Spectral measurements of howardites in support of the interpretation of the Dawn VIR spectra at Vesta

    The howardites, eucrites, and diogenites constitute a suite of meteorite lithologies (HED) known to be related to asteroid Vesta [1]. Howardites are physical mixtures of eucrites and diogenites. Howardites are divided in two subtypes: regolithic howardites are actually linked to the true regolith, while fragmental howardites are simple polymict breccias [2]. Mapping of Vesta's surface, as obtained with data from Visible and Infrared mapping Spectrometer (VIR) on Dawn [3,4], showed that it is mainly howarditic, with few regions of diogenite-rich and eucrite-rich terrains [5, 6]. In order to map quantitatively the distribution of lithologic types on Vesta, we are carrying on a study of a set of well-characterized howardites [7]. Spectra were measured on sample powders sieved to 75 μ m in the laboratories of the Istituto di Astrofisica e Planetologia Spaziali (IAPS-INAF) in Rome (Italy) and Brown University, in Providence (USA). Here we report about the measurements done at IAPS-INAF. The spectra of 33 samples have been acquired with the S.LAB setup, consisting in the FieldSpec Pro spectrometer (range 0.35-2.5 μ m, spatial resolution 0.5 cm^2) coupled with a goniometer (incidence i=30°, emission e=0°) [8]. Some representative spectra of the measured howardites are shown in the figure. The spectra are characterized by the two broad Fe^{2+} absorption bands near 1 and 2 μ m (BI and BII) indicative of pyroxenes. Band parameters relative to BI and BII have been calculated using the algorithm developed to process VIR spectra [4]. This enables us to compare laboratory data directly with the VIR results. Other weaker absorptions also characterize some spectra: the 0.5 μ m feature (Mn^{2+} or Cr^{3+}) and the 1.2 μ m feature possibly due to Fe^{2+} in plagioclases. The PRA04401 sample is characterized by a pyroxene-carbonaceous matter mixture [7].

    Full Text Available Simulation of the interactions between particles and matter in studies for developing X-rays detectors generally requires very long calculation times (up to several days or weeks. These times are often a serious limitation for the success of the simulations and for the accuracy of the simulated models. One of the tools used by the scientific community to perform these simulations is Geant4 (Geometry And Tracking [2, 3]. On the best of experience in the design of the AVES cluster computing system, Federici et al. [1], the IAPS (Istituto di Astrofisica e Planetologia Spaziali INAF laboratories were able to develop a cluster computer system dedicated to Geant 4. The Cluster is easy to use and easily expandable, and thanks to the design criteria adopted it achieves an excellent compromise between performance and cost. The management software developed for the Cluster splits the single instance of simulation on the cores available, allowing the use of software written for serial computation to reach a computing speed similar to that obtainable from a native parallel software. The simulations carried out on the Cluster showed an increase in execution time by a factor of 20 to 60 compared to the times obtained with the use of a single PC of medium quality.

    In the last decades the growing interest in the evaluation of the underwater acoustic noise for studies in the fields of geology, biology and high-energy physics is driving the scientific community to collaborate towards a multidisciplinary approach to the topic. In June 2012 in the framework of the European project EMSO, a multidisciplinary underwater observatory, named NEMO-SN1, was installed 25 km off-shore the port of Catania, at a depth of 2100 m and operated until May 2013 by INFN (Istituto Nazionale di Fisica Nucleare) and INGV (Istituto Nazionale di Geofisica e Vulcanologia). NEMO-SN1 hosted aboard geophysical, oceanographic and acoustic sensors: among these a seismic hydrophone model SMID DT-405D(V). In this work, conducted within the activity of the SMO project, the results on the evaluation of the underwater acoustic pollution in the Gulf of Catania through SMID DT-405D(V) recordings are presented. The seismic hydrophone provided a data set of about 11 months of continuous (24/7) recordings. Underwater sounds have been continuously digitized at a sampling frequency of 2 kHz and the acquired data have been stored in 10min long files for off-line analysis. To describe one-year background noise levels, the mean integrated acoustic noise was measured every second (sampling frequency 2000, NFFT 2048) in the 1/3 octave bands with centre frequency 63 Hz and for each 10 minutes-long file the 5th, the 50th and the 98th percentiles were calculated. Measured noise was correlated with the shipping traffic in the area, thanks to the data provided by an AIS receiver installed at the INFN-Laboratori Nazionali del Sud. An acoustic noise increment was measured in coincidence with the passing of crafts in the area and it was possible to identify the characteristic spectrum of each ship. A simple model for the estimation of the acoustic noise induced by the ships passing through the area was developed. The model was applied by using AIS data acquired during the operation

Because of its economic and political meaning, this special form of state monopoly gave rise to many reactions in the financial and political national context, and so INA started its first years of activity in a troubled and unstable situation. The essay also discusses about the repercussions on international insurance market in consequence of the foundation of INA.During the ten-year perior of partial monopoly of the Institute in life insurance sector (1912-1922, foreign insurance companies deemed their financial interest in Italian market jeopardized, and contrasted with it until 1923, when a new act reformed life insurance market, abrogating monopoly system.

    Lung cancer is the leading cause of cancer-related mortality in developed countries. Only 10-15% of all men and women diagnosed with lung cancer live 5 years after the diagnosis. However, the 5-year survival rate for patients diagnosed in the early asymptomatic stage of the disease can reach 70%. Early-stage lung cancers can be diagnosed by detecting non-calcified small pulmonary nodules with computed tomography (CT). Computer-aided detection (CAD) could support radiologists in the analysis of the large amount of noisy images generated in screening programs, where low-dose and thin-slice settings are used. The MAGIC-5 project, funded by the Istituto Nazionale di Fisica Nucleare (INFN, Italy) and Ministero dell'Universita e della Ricerca (MUR, Italy), developed a multi-method approach based on three CAD algorithms to be used in parallel with a merging of their results: the Channeler Ant Model (CAM), based on Virtual Ant Colonies, the Dot-Enhancement/Pleura Surface Normals/VBNA (DE-PSN-VBNA), and the Region Growing Volume Plateau (RGVP). Preliminary results show quite good performances, to be improved with the refining of the single algorithm and the added value of the results merging.

    Full Text Available The MAGFLOW lava simulation model is a cellular automaton developed by the Sezione di Catania of the Istituto Nazionale di Geofisica e Vulcanologia (INGV and it represents the peak of the evolution of cell-based models for lava-flow simulation. The accuracy and adherence to reality achieved by the physics-based cell evolution of MAGFLOW comes at the cost of significant computational times for long-running simulations. The present study describes the efforts and results obtained by porting the original serial code to the parallel computational platforms offered by modern video cards, and in particular to the NVIDIA Compute Unified Device Architecture (CUDA. A number of optimization strategies that have been used to achieve optimal performance on a graphic processing units (GPU are also discussed. The actual benefits of running on the GPU rather than the central processing unit depends on the extent and duration of the simulated event; for large, long-running simulations, the GPU can be 70-to-80-times faster, while for short-lived eruptions with a small extents the speed improvements obtained are 40-to-50 times.

    A monolithic silicon device consisting of a matrix of micrometric cylindrical diodes (about 2 μm in thickness and 9 μm in diameter) coupled to a residual energy measurement stage E (about 500 μm in thickness) was proposed and studied for assessing the quality of a therapeutic proton beam. The device was placed at different depths inside a polymethyl-methacrylate phantom and irradiated with a modulated 62 MeV proton beam at the Centro di AdroTerapia e Applicazioni Nucleari Avanzate (CATANA) of the Laboratori Nazionali del Sud (LNS, Catania, Italy) of the Istituto Nazionale di Fisica Nucleare (INFN). At each phantom depth, the energy imparted in the two detector stages was measured event-by-event in coincidence mode. The distributions of the energy imparted to the cylindrical diodes were corrected for tissue-equivalence by applying an optimized procedure. In order to perform a comparison with literature data measured with a cylindrical TEPC, the distributions derived with the silicon detector were corrected for shape-equivalence. The agreement with the microdosimetric spectra measured with the TEPC was satisfactory above the detection limit imposed by the electronic noise of the silicon-based system.

    Superconducting accelerators, such as the International Linear Collider (ILC), rely on very high Q accelerating cavities to achieve high electric fields at low RF power. Such cavities have very narrow resonances: a few kHz with a 1.3GHz resonance frequency for the ILC. Several mechanical factors cause tune shifts much larger than this: pressure variations in the liquid helium bath; microphonics from pumps and other mechanical devices; and for a pulsed machine such as the ILC, Lorentz force detuning (pressure from the contained RF field). Simple passive stiffening is limited by many manufacturing and material considerations. Therefore, active tuning using piezo actuators is needed. Here we study a supply for their operation. Since commercial power amplifiers are expensive, we analyzed the characteristics of four power amplifiers: (iPZD) built by Istituto Nazionale di Fisica Nucleare (Sezione di Pisa); and a DC-DC converter power supply built in Fermilab (Piezo Master); and two commercial amplifiers, Piezosystem jena and Piezomechanik. This paper presents an analysis and characterization of these amplifiers to understand the cost benefit and reliability when using in a large scale, pulsed beam accelerator like the ILC.

    Full Text Available The detection and evaluation of the status of disposal sites that contain hazardous waste materials is becoming an increasingly important element in environmental investigations. Close cooperation between the Istituto Nazionale di Geofisica e Vulcanologia (INGV; National Institute of Volcanology and Geophysics in Rome and the Italian environmental police has resulted in numerous underground investigations of different buried materials. Among the geophysical investigation tools, magnetometry is the most effective, rapid and precise of all of the geophysical methods for localizing buried steel drums. Analysis of magnetic map anomalies can provide a variety of information about buried materials, including extension, distribution and depth, with processing of the acquired magnetic data. This information is also very useful in case of excavations that are aimed at the recovery of hazardous waste. This study determines the most relevant analyses reported in the literature, with modeling of magnetometric methods for environmental applications both theoretically and experimentally. Some studies and research results achieved by the INGV in relation to magnetic anomalies produced by buried steel drums are also reported, as found in field operations and as achieved from test sites.

    We present a search for the decay B^0_sarrow e μ. This decay is strictly forbidden within the standard model of electroweak interaction. However, extensions to the standard model exist which predict a symmetry between quarks and leptons and one of the signals predicted by these models is the decay B^0_sarrow e μ. An example of such model is the Pati-Salam model. We present the first limit on Br(B^0_sarrow e μ). From this limit we derive a mass limit on the Pati-Salam leptoquark mass. ^ Supported by U.S. DOE DE-AC03-76SF00098. ^ Supported by U.S. DOE DE-AC02-76CHO3000. ^*We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

    For t\\overlinet events decaying into a leptonic W and four jets, it is possible to fully reconstruct the four-momenta of the top and antitop quarks as well as their decay products. We use this feature to plot the distributions of several kinematical variables such as the transverse momentum and rapidity of the top quark and the t\\overlinet system, the azimuthal separation between the top and anti-top, and the t\\overlinet invariant mass. We compare 110 pb-1 of CDF data with the expected mixture of t\\overlinet and background Monte Carlo calculations. There is no indication for substantial deviation from the standard model at the current level of statistics.

  15. VI European Summer School on Experimental Nuclear Astrophysics

    Science.gov (United States)

    The European Summer School on Experimental Nuclear Astrophysics has reached the sixth edition, marking the tenth year's anniversary. The spirit of the school is to provide a very important occasion for a deep education of young researchers about the main topics of experimental nuclear astrophysics. Moreover, it should be regarded as a forum for the discussion of the last-decade research activity. Lectures are focused on various aspects of primordial and stellar nucleosynthesis, including novel experimental approaches and detectors, indirect methods and radioactive ion beams. Moreover, in order to give a wide educational offer, some lectures cover complementary subjects of nuclear astrophysics such as gamma ray astronomy, neutron-induced reactions, short-lived radionuclides, weak interaction and cutting-edge facilities used to investigate nuclear reactions of interest for astrophysics. Large room is also given to young researcher oral contributions. Traditionally, particular attention is devoted to the participation of students from less-favoured countries, especially from the southern coast of the Mediterranean Sea. The school is organised by the Catania Nuclear Astrophysics research group with the collaboration of Dipartimento di Fisica e Astromomia - Università di Catania and Laboratori Nazionali del Sud - Istituto Nazionale di Fisica Nucleare.

    We present a search for new particles decaying to dijets using CDF data from the 1992-3 and 1993-5 runs. The dijet mass spectrum extends from 180 GeV/c^2 to about 1 TeV/c^2. Fitting the data to a smooth background function plus a mass resonance, we obtain prelimary upper limits on the cross section for new particles as a function of mass. We use this to set mass limits on axigluons, excited quarks, technirhos and other new particles. We also search the dijet angular distributions for indications of new physics. ^ Supported by U.S. DOE under Contract No. DE-FG05-91ER40665. ^ Supported by U.S. DOE under Contract No. DE-AC02-76CH03000. ^*We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

    Full Text Available The Talmud manuscripts Magl. coll. II.I.8 and 9 of the Biblioteca Nazionale Centrale of Florence contain marginal Talmud-translations in Latin which correspond to the 13th century translation Extractiones de Talmud. The two manuscripts are described and their textual evidence is compared both with the Latin manuscript tradition of the Extractiones and with the Hebrew/Aramaic Talmudic text which they contain, trying to answer the question of whether the Florence manuscripts are the Vorlage of the Latin translation of the Talmud. The matter reveals itself as complex: striking analogies seem to suggest an affirmative answer to the question at stake; however, evidence can also be found which rather supports the opposite conclusion. Nevertheless, the Florence manuscripts certainly belong to a Hebrew/Aramaic tradition which is very close to the Vorlage of the Extractiones. Moreover, the Latin text they offer in their magins reflects a prior stage of work in the production of the Extractiones, featuring unique variants and passages, which are corrected or omitted in the rest of the Latin manuscript tradition.

    Full Text Available At 01:36 UTC (03:36 local time on August 24th 2016, an earthquake Mw 6.0 struck an extensive sector of the central Apennines (coordinates: latitude 42.70° N, longitude 13.23° E, 8.0 km depth. The earthquake caused about 300 casualties and severe damage to the historical buildings and economic activity in an area located near the borders of the Umbria, Lazio, Abruzzo and Marche regions. The Istituto Nazionale di Geofisica e Vulcanologia (INGV located in few minutes the hypocenter near Accumoli, a small town in the province of Rieti. In the hours after the quake, dozens of events were recorded by the National Seismic Network (Rete Sismica Nazionale, RSN of the INGV, many of which had a ML > 3.0. The density and coverage of the RSN in the epicentral area meant the epicenter and magnitude of the main event and subsequent shocks that followed it in the early hours of the seismic sequence were well constrained. However, in order to better constrain the localizations of the aftershock hypocenters, especially the depths, a denser seismic monitoring network was needed. Just after the mainshock, SISMIKO, the coordinating body of the emergency seismic network at INGV, was activated in order to install a temporary seismic network integrated with the existing permanent network in the epicentral area. From August the 24th to the 30th, SISMIKO deployed eighteen seismic stations, generally six components (equipped with both velocimeter and accelerometer, with thirteen of the seismic station transmitting in real-time to the INGV seismic monitoring room in Rome. The design and geometry of the temporary network was decided in consolation with other groups who were deploying seismic stations in the region, namely EMERSITO (a group studying site-effects, and the emergency Italian strong motion network (RAN managed by the National Civil Protection Department (DPC. Further 25 BB temporary seismic stations were deployed by colleagues of the British Geological Survey

    The Large Binocular Telescope Observatory (LBTO), a joint scientific venture between the Instituto Nazionale di Astrofisica (INAF), LBT Beteiligungsgesellschaft (LBTB), University of Arizona, Ohio State University (OSU), and the Research Corporation, is one of the newest additions to the world's collection of large optical/infrared ground-based telescopes. With its unique, twin 8.4m mirror design providing a 22.8 meter interferometric baseline and the collecting area of an 11.8m telescope, LBT has a window of opportunity to exploit its singular status as the "first" of the next generation of Extremely Large Telescopes (ELTs). Prompted by urgency to maximize scientific output during this favorable interval, LBTO recently re-evaluated its operations model and developed a new strategy that augments classical observing with queue. Aided by trained observatory staff, queue mode will allow for flexible, multi-instrument observing responsive to site conditions. Our plan is to implement a staged rollout that will provide many of the benefits of queue observing sooner rather than later - with more bells and whistles coming in future stages. In this paper, we outline LBTO's new scientific model, focusing specifically on our "lean" resourcing and development, reuse and adaptation of existing software, challenges presented from our one-of-a-kind binocular operations, and lessons learned. We also outline further stages of development and our ultimate goals for queue.

    The Gran Sasso National Laboratory of INFN (LNGS) is the largest underground laboratory for astroparticle physics in the world. Located in Italy between the cities of L'Aquila and Teramo, 120 km far from Rome, is a research infrastructure mainly dedicated to astroparticle and neutrino physics. It offers the most advanced underground facility in terms of dimensions, complexity and completeness of its infrastructures. LNGS is one of the four national laboratories run by the Istituto Nazionale di Fisica Nucleare (INFN). The scientific program at LNGS is mainly focused on astroparticle, particle and nuclear physics. The laboratory presently hosts many experiments as well as R&D activities, including world-leading research in the fields of solar neutrinos, accelerator neutrinos (CNGS neutrino beam from CERN to Gran Sasso), dark matter (DM), neutrinoless double beta decay (2β0ν) and nuclear cross-section of astrophysical interest. Associate sciences like earth physics, biology and fundamental physics complement the activities. The laboratory is operated as an international science facility and hosts experiments whose scientific merit is assessed by an international advisory Scientific Committee. A review of the main experiments carried out at LNGS will be given, together with the most recent and relevant scientific results achieved.

  5. Spatial and temporal distribution of vertical ground movements at Mt. Vesuvius in the period 1973-2009

    2013-11-01

    Full Text Available Since the early ’70s vertical ground movements at Mount Vesuvius area have been investigated and monitored by the Osservatorio Vesuviano (Isti-tuto Nazionale di Geofisica Vulcanologia - Osservatorio Vesuviano since 2001. This monitoring began with the installation of a high-precision leveling line in the region at medium-high elevations on the volcano. The deformation pattern and expected strain field assessment methods in the volcanic structure induced by inner sources has demanded in subsequent years the expansion of the leveling network up to cover the whole volcanic area, enclosing part of leveling lines of other institutions. As a result of this expansion, the Mt. Vesuvius Area Leveling Network (VALN has today reached a length of about 270 km and consists of 359 benchmarks. It is configured in 21 circuits and is connected, westward, to the Campi Flegrei leveling network and, northward, to the Campania Plain leveling network. The data collected have been carefully re-analyzed for random and systematic errors and for error propagation along the leveling lines to identify the areas affected by significant ground movements. For each survey, the data were rigorously adjusted and vertical ground movements were evaluated by differentiating the heights calculated by the various measurements conducted by the Osservatorio Vesuviano from 1973 to 2009.

    The Open Computing Cluster for Advanced data Manipulation (OCCAM) is a multipurpose flexible HPC cluster designed and operated by a collaboration between the University of Torino and the Sezione di Torino of the Istituto Nazionale di Fisica Nucleare. It is aimed at providing a flexible, reconfigurable and extendable infrastructure to cater to a wide range of different scientific computing use cases, including ones from solid-state chemistry, high-energy physics, computer science, big data analytics, computational biology, genomics and many others. Furthermore, it will serve as a platform for R&D activities on computational technologies themselves, with topics ranging from GPU acceleration to Cloud Computing technologies. A heterogeneous and reconfigurable system like this poses a number of challenges related to the frequency at which heterogeneous hardware resources might change their availability and shareability status, which in turn affect methods and means to allocate, manage, optimize, bill, monitor VMs, containers, virtual farms, jobs, interactive bare-metal sessions, etc. This work describes some of the use cases that prompted the design and construction of the HPC cluster, its architecture and resource provisioning model, along with a first characterization of its performance by some synthetic benchmark tools and a few realistic use-case tests.

    Dolphins emit short ultrasonic pulses (clicks) to acquire information about the surrounding environment, prey and habitat features. We investigated Delphinidae activity over multiple temporal scales through the detection of their echolocation clicks, using long-term Passive Acoustic Monitoring (PAM). The Istituto Nazionale di Fisica Nucleare operates multidisciplinary seafloor observatories in a deep area of the Central Mediterranean Sea. The Ocean noise Detection Experiment collected data offshore the Gulf of Catania from January 2005 to November 2006, allowing the study of temporal patterns of dolphin activity in this deep pelagic zone for the first time. Nearly 5,500 five-minute recordings acquired over two years were examined using spectrogram analysis and through development and testing of an automatic detection algorithm. Echolocation activity of dolphins was mostly confined to nighttime and crepuscular hours, in contrast with communicative signals (whistles). Seasonal variation, with a peak number of clicks in August, was also evident, but no effect of lunar cycle was observed. Temporal trends in echolocation corresponded to environmental and trophic variability known in the deep pelagic waters of the Ionian Sea. Long-term PAM and the continued development of automatic analysis techniques are essential to advancing the study of pelagic marine mammal distribution and behaviour patterns.

    This work is concerned with the design of a readout chip for application to experiments at the next generation X-ray Free Electron Lasers (FEL). The ASIC, named PixFEL Matrix (PFM2), has been designed in a 65 nm CMOS technology and consists of 32 × 32 pixels. Each cell covers an area of 110 × 110 μm2 and includes a low-noise charge sensitive amplifier (CSA) with dynamic signal compression, a time-variant shaper used to process the preamplifier output signal, a 10-bit successive approximation register (SAR) analog-to-digital converter (ADC) and digital circuitry for channel control and data readout. Two different solutions for the readout channel, based on different versions of the time-variant filter, have been integrated in the chip. Both solutions can be operated in such a way to cope with the high frame rate (exceeding 1 MHz) foreseen for future X-ray FEL machines. The ASIC will be bump bonded to a slim/active edge pixel sensor to form the first demonstrator for the PixFEL X-ray imager. This work has been carried out in the frame of the PixFEL project funded by Istituto Nazionale di Fisica Nucleare (INFN), Italy.

    Transition probabilities of intermediate-spin yrast and non-yrast excitations in Se,8280 were investigated in a recoil distance Doppler-shift (RDDS) experiment performed at the Istituto Nazionale di Fisica Nucleare, Laboratori Nazionali di Legnaro. The Cologne Plunger device for deep inelastic scattering was used for the RDDS technique and was combined with the AGATA Demonstrator array for the γ -ray detection and coupled to the PRISMA magnetic spectrometer for an event-by-event particle identification. In 80Se, the level lifetimes of the yrast (61+) and (81+) states and of a non-yrast band feeding the yrast 41+ state are determined. A spin and parity assignment of the head of this sideband is discussed based on the experimental results and supported by large-scale shell-model calculations. In 82Se, the level lifetimes of the yrast 61+ state and the yrare 42+ state and lifetime limits of the yrast (101+) state and of the 51- state are determined. Although the experimental results contain large uncertainties, they are interpreted with care in terms of large-scale shell-model calculations using the effective interactions JUN45 and jj44b. The excited states' wave functions are investigated and discussed with respect to the role of the neutron g9 /2 orbital.

    An observation of neutrinoless double beta (0νββ) decay would allow to shed light onto the nature of neutrinos. GERDA (GERmanium Detector Array) aims to discover this process in a background-free search using 76Ge. The experiment is located at the Laboratori Nazionali del Gran Sasso (LNGS) of the Istituto Nazionale di Fisica Nucleare (INFN) in Italy. Bare, isotopically enriched, high purity germanium detectors are operated in liquid argon. GERDA follows a staged approach. In Phase II 35.6 kg of enriched germanium detectors are operated since December 2015. The application of active background rejection methods, such as a liquid argon scintillation light read-out and pulse shape discrimination of germanium detector signals, allows to reduce the background index to the intended level of 10‑3 cts/(keVṡkgṡyr). No evidence for the 0νββ decay has been found in 23.2 kgṡyr of Phase II data, and together with data from Phase I the up-to-date most stringent half-life limit for this process in 76Ge has been established, at a median sensitivity of 5.8ṡ1025yr the 90% C.L. lower limit is 8.0ṡ1025yr.

    The Isotope Separation On-Line (ISOL) method for the production of Radioactive Ion Beams (RIB) is attracting significant interest in the worldwide nuclear physics community. Within this context the SPES (Selective Production of Exotic Species) RIB facility is now under construction at INFN LNL (Istituto Nazionale di Fisica Nucleare Laboratori Nazionali di Legnaro). This technique is established as one of the main techniques for high intensity and high quality beams production. The SPES facility will produce n-rich isotopes by means of a 40 MeV proton beam, emitted by a cyclotron, impinging on a uranium carbide multi-foil fission target. The aim of this work is to describe the most important results obtained by the study of the on-line behavior of the SPES production target assembly. This target system will produce RIBs at a rate of about 1013 fissions per second, it will be able to dissipate a total power of up to 10 kW, and it is planned to work continuously for 2 week-runs of irradiation. ISOL beams of 24 different elements will be produced, therefore a target and ion source development is ongoing to ensure a great variety of produced isotopes and to improve the beam intensity and purity.

    The reaction 23Na(p, γ)24Mg can provide a link from the NeNa to the MgAl cycle in stellar burning and is therefore of interest in nuclear astrophysics. To determine the reaction rates at stellar temperatures, new cross section measurements at low proton energies have been performed recently, and further experiments are underway. The current cross section data implies that the reaction rate up to temperatures of 1 GK is determined by a few narrow resonances and direct capture. Complementary to these experimental efforts at low proton energies, cross section measurements at higher energies can help to constrain the direct capture and broad resonance contributions to the cross section and reduce the uncertainty of the extrapolation towards stellar energies. In this paper we report an experiment to measure the 23Na(p, γ)24Mg cross section with a solid target setup at the St. ANA 5U accelerator at the University of Notre Dame. The experiment and the current status of data analysis will be described. This work benefited from support by the National Science Foundation under Grant No. PHY-1430152 (JINA-CEE), the Nuclear Science Laboratory (NSL), the Istituto Nazionale di Fisica Nucleare (INFN), and the Gran Sasso Science Institute (GSSI).

    Facilities making use of the Isotope Separator On-Line (ISOL) method for the production of Radioactive Ion Beams (RIB) attract interest because they can be used for nuclear structure and reaction studies, astrophysics research and interdisciplinary applications. The ISOL technique is based on the fast release of the nuclear reaction products from the chosen target material together with their ionization into short-lived nuclei beams. Within this context, the SPES (Selective Production of Exotic Species) facility is now under construction in Italy at INFN-LNL (Istituto Nazionale di Fisica Nucleare — Laboratori Nazionali di Legnaro). The SPES facility will produce RIBs mainly from n-rich isotopes obtained by a 40 MeV cyclotron proton beam (200 μA) directly impinging on a uranium carbide multi-foil fission target. The aim of this work is to describe and update, from a comprehensive point of view, the most important results obtained by the analysis of the on-line behavior of the SPES production target assembly. In particular an improved target configuration has been studied by comparing different codes and physics models: the thermal analyses and the isotope production are re-evaluated. Then some consequent radioprotection aspects, which are essential for the installation and operation of the facility, are presented.

    Reduced quadrupole transition probabilities for low-lying transitions in neutron-rich Se,8684 are investigated with a recoil distance Doppler shift (RDDS) experiment. The experiment was performed at the Istituto Nazionale di Fisica Nucleare (INFN) Laboratori Nazionali di Legnaro using the Cologne Plunger device for the RDDS technique and the AGATA Demonstrator array for the γ -ray detection coupled to the PRISMA magnetic spectrometer for an event-by-event particle identification. In 86Se the level lifetime of the yrast 21+ state and an upper limit for the lifetime of the 41+ state are determined for the first time. The results of 86Se are in agreement with previously reported predictions of large-scale shell-model calculations using Ni78-I and Ni78-II effective interactions. In addition, intrinsic shape parameters of lowest yrast states in 86Se are calculated. In semimagic 84Se level lifetimes of the yrast 41+ and 61+ states are determined for the first time. Large-scale shell-model calculations using effective interactions Ni78-II, JUN45, jj4b, and jj4pna are performed. The calculations describe B (E 2 ;21+→01+) and B (E 2 ;61+→41+) fairly well and point out problems in reproducing the experimental B (E 2 ;41+→21+) .

    The fabrication and characterization of a charged particle imaging system composed of a tracker and a residual range detector (RRD) is described. The tracker is composed of four layers of scintillating fibers (SciFi), 500 μm side square section, arranged to form two planes orthogonal to each other. The fibers are coupled to two Multi-Pixel Photon Counter (MPPC) arrays by means of a channel reduction system patented by the Istituto Nazionale di Fisica Nucleare (INFN) (Presti, 2015) . Sixty parallel layers of the same fibers used in the tracker compose the RRD. The various layers are optically coupled to a MPPC array by means of wavelength shifting (WLS) fibers. The sensitive area of the two detectors is 9×9 cm"2. The results of the measurements, acquired by the prototypes with CATANA (Cirrone, 2008) proton beam, and a comparison with the simulations of the detectors are presented. - Highlights: • A real time charged particle imaging system is described. • The system is composed of a position sensitive and a residual range detectors. • The sensitive area of the system is composed of submillimeter scintillating fibers. • The read-out is based on a patented channel reduction system. • The results of the measurements with proton beam are presented.

    Neutrons constitute an important component of the radiation environment in hadron therapy accelerators. Their energy distribution may span from thermal up to hundred of MeV. The characterization of these fields in terms of dosimetric or spectrometric quantities is crucial for either the patient protection or the facility design aspects. To date, the Extended Range Bonner Sphere Spectrometer (ERBSS) is the only instrument able to simultaneously determine all spectral components in such workplaces. With the aim of providing useful data to the scientific community involved in neutron measurements at hadron therapy facilities, a measurement campaign was carried out at the Centro di AdroTerapia e Applicazioni Nucleari Avanzate (CATANA) of INFN-LNS (Laboratori Nazionali del Sud), where a 62 AMeV carbon ion is available. The beam was directed towards a PMMA phantom, simulating the patient, and two neutron measurement points were established at 0° and 90° with respect to the beam-line. The ERBSSs of UAB (Universidad Autónoma de Barcelona-Grup de Física de les Radiacions) and INFN (Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali di Frascati) were used to measure the resulting neutron fields. The two ERBSSs use different detectors and sphere diameters, and have been independently calibrated. The FRUIT code was used to unfold the results.

    At the Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali del Sud (INFN-LNS) in Catania, Italy, the first Italian protontherapy facility, named Centro di AdroTerapia e Applicazioni Nucleari Avanzate (CATANA) has been built in collaboration with the University of Catania. It is based on the use of the 62-MeV proton beam delivered by the K=800 Superconducting Cyclotron installed and working at INFN-LNS since 1995. The facility is mainly devoted to the treatment of ocular diseases like uveal melanoma. A beam treatment line in air has been assembled together with a dedicated positioning patient system. The facility has been in operation since the beginning of 2002 and 66 patients have been successfully treated up to now. The main features of CATANA together with the clinical and dosimetric features will be extensively described; particularly, the proton beam line, that has been entirely built at LNS, with all its elements, the experimental transversal and depth dose distributions of the 62-MeV proton beam obtained for a final collimator of 25-mm diameter and the experimental depth dose distributions of a modulated proton beam obtained for the same final collimator. Finally, the clinical results over 1 yr of treatments, describing the features of the treated diseases will be reported.

    Beato Angelico is one of the most important Italian painters of the Renaissance period, in particular he was a master of the so-called 'Buon fresco' technique for mural paintings. A wide diagnostic campaign with X-Ray Fluorescence (XRF) analyses has been carried out on three masterworks painted by Beato Angelico in the San Marco monastery in Florence: the Crocifissione con Santi, the 'Annunciazione' and the 'Madonna delle Ombre'. The latter is painted by mixing fresco and secco techniques, which makes it of particular interest for the study of two different paintings techniques of the same artist. Then the aim of the study was focused on the characterization of the painting palette, and therefore the painting techniques, used by Beato Angelico. Moreover, the conservators were interested in the study of degradation processes and old restoration treatments. Our analyses have been carried out by means of the XRF spectrometer developed at LABEC laboratory at Istituto Nazionale di Fisica Nucleare in Florence (Italy). XRF is indeed especially suited for such a kind of study, allowing for multi-elemental, nondestructive, non-invasive analyses in a short time, with portable instruments. In this paper the first results concerning the XRF analysis are presented.

    The fabrication and characterization of a charged particle imaging system composed of a tracker and a residual range detector (RRD) is described. The tracker is composed of four layers of scintillating fibers (SciFi), 500 μm side square section, arranged to form two planes orthogonal to each other. The fibers are coupled to two Multi-Pixel Photon Counter (MPPC) arrays by means of a channel reduction system patented by the Istituto Nazionale di Fisica Nucleare (INFN) (Presti, 2015) . Sixty parallel layers of the same fibers used in the tracker compose the RRD. The various layers are optically coupled to a MPPC array by means of wavelength shifting (WLS) fibers. The sensitive area of the two detectors is 9×9 cm{sup 2}. The results of the measurements, acquired by the prototypes with CATANA (Cirrone, 2008) proton beam, and a comparison with the simulations of the detectors are presented. - Highlights: • A real time charged particle imaging system is described. • The system is composed of a position sensitive and a residual range detectors. • The sensitive area of the system is composed of submillimeter scintillating fibers. • The read-out is based on a patented channel reduction system. • The results of the measurements with proton beam are presented.

    The U.S. Geological Survey (USGS) "Did You Feel It?" (DYFI) system is an automated approach for rapidly collecting macroseismic intensity data from Internet users' shaking and damage reports and generating intensity maps immediately following earthquakes; it has been operating for over a decade (1999-2011). DYFI-based intensity maps made rapidly available through the DYFI system fundamentally depart from more traditional maps made available in the past. The maps are made more quickly, provide more complete coverage and higher resolution, provide for citizen input and interaction, and allow data collection at rates and quantities never before considered. These aspects of Internet data collection, in turn, allow for data analyses, graphics, and ways to communicate with the public, opportunities not possible with traditional data-collection approaches. Yet web-based contributions also pose considerable challenges, as discussed herein. After a decade of operational experience with the DYFI system and users, we document refinements to the processing and algorithmic procedures since DYFI was first conceived. We also describe a number of automatic post-processing tools, operations, applications, and research directions, all of which utilize the extensive DYFI intensity datasets now gathered in near-real time.

    Laser accelerated proton beams represent nowadays an attractive alternative to the conventional ones and they have been proposed in different research fields. In particular, the interest has been focused in the possibility of replacing conventional accelerating machines with laser-based accelerators in order to develop a new concept of hadrontherapy facilities, which could result more compact and less expensive. With this background the ELIMED (ELIMED: ELI-Beamlines MEDical applications) research project has been launched by LNS-INFN researchers (Laboratori Nazionali del Sud-Istituto Nazionale di Fisica Nucleare, Catania, IT) and ASCR-FZU researchers (Academy of Sciences of the Czech Republic-Fyzikální ústar, Prague, Cz), within the pan-European ELI-Beamlines facility framework. Its main purposes are the demonstration of future applications in hadrontherapy of optically accelerated protons and the realization of a laser-accelerated ion transport beamline for multidisciplinary applications. Several challenges, starting from laser-target interaction and beam transport development, up to dosimetric and radiobiological issues, need to be overcome in order to reach the final goals. The design and the realization of a preliminary beam handling and dosimetric system and of an advanced spectrometer for high energy (multi-MeV) laser-accelerated ion beams will be shortly presented in this work.

    This work is concerned with the design of a readout chip for application to experiments at the next generation X-ray Free Electron Lasers (FEL). The ASIC, named PixFEL Matrix (PFM2), has been designed in a 65 nm CMOS technology and consists of 32 × 32 pixels. Each cell covers an area of 110 × 110 μm 2 and includes a low-noise charge sensitive amplifier (CSA) with dynamic signal compression, a time-variant shaper used to process the preamplifier output signal, a 10-bit successive approximation register (SAR) analog-to-digital converter (ADC) and digital circuitry for channel control and data readout. Two different solutions for the readout channel, based on different versions of the time-variant filter, have been integrated in the chip. Both solutions can be operated in such a way to cope with the high frame rate (exceeding 1 MHz) foreseen for future X-ray FEL machines. The ASIC will be bump bonded to a slim/active edge pixel sensor to form the first demonstrator for the PixFEL X-ray imager. This work has been carried out in the frame of the PixFEL project funded by Istituto Nazionale di Fisica Nucleare (INFN), Italy.

    The Project called Sistema Rischio Vulcanico (SRV) is funded by the Italian Space Agency (ASI) in the frame of the National Space Plan 2003-2005 under the Earth Observations section for natural risks management. The SRV Project is coordinated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) which is responsible at national level for the volcanic monitoring. The objective of the project is to develop a pre-operative system based on EO data and ground measurements integration to support the volcanic risk monitoring of the Italian Civil Protection Department which requirements and need are well integrated in the GMES Emergency Core Services program. The project philosophy is to implement, by incremental versions, specific modules which allow to process, store and visualize through Web GIS tools EO derived parameters considering three activity phases: 1) knowledge and prevention; 2) crisis; 3) post crisis. In order to combine effectively the EO data and the ground networks measurements the system will implement a multi-parametric analysis tool, which represents and unique tool to analyze contemporaneously a large data set of data in "near real time". The SRV project will be tested his operational capabilities on three Italian Volcanoes: Etna,Vesuvio and Campi Flegrei.

    Full Text Available In this paper we describe the results of a project ongoing at the Istituto Nazionale di Geofisica e Vulcanologia (INGV. The objective is to develop and implement a system for monitoring and forecasting volcanic plumes of Etna. Monitoring is based at present by multispectral infrared measurements from the Spin Enhanced Visible and Infrared Imager on board the Meteosat Second Generation geosynchronous satellite, visual and thermal cameras, and three radar disdrometers able to detect ash dispersal and fallout. Forecasting is performed by using automatic procedures for: i downloading weather forecast data from meteorological mesoscale models; ii running models of tephra dispersal, iii plotting hazard maps of volcanic ash dispersal and deposition for certain scenarios and, iv publishing the results on a web-site dedicated to the Italian Civil Protection. Simulations are based on eruptive scenarios obtained by analysing field data collected after the end of recent Etna eruptions. Forecasting is, hence, supported by plume observations carried out by the monitoring system. The system was tested on some explosive events occurred during 2006 and 2007 successfully. The potentiality use of monitoring and forecasting Etna volcanic plumes, in a way to prevent threats to aviation from volcanic ash, is finally discussed.

    2017-01-01

    The accurate determination of gaseous pollutants is fundamental for the monitoring of the trends of these analytes in the environment and the application of the metrological concepts to this field is necessary to assure the reliability of the measurement results. In this work, an overview of the activity carried out at Istituto Nazionale di Ricerca Metrologica to establish the metrological traceability of the measurements of gaseous atmospheric pollutants, in particular of carbon dioxide (CO 2 ), is presented. Two primary methods, the gravimetry and the dynamic dilution, are used for the preparation of reference standards for composition which can be used to calibrate sensors and analytical instrumentation. At present, research is carried out to lower the measurement uncertainties of the primary gas mixtures and to extend their application to the oceanic field. The reason of such investigation is due to the evidence of the changes occurring in seawater carbonate chemistry, connected to the rising level of CO 2 in the atmosphere. The well established activity to assure the metrological traceability of CO 2 in the atmosphere will be applied to the determination of CO 2 in seawater, by developing suitable reference materials for calibration and control of the sensors during their routine use.

    We present the preliminary results of a search for new heavy charged vector bosons using 110 pb-1 of data collected with the CDF detector during the 1992--95 Tevatron collider runs at Fermilab. We identify candidate events which contain an electron and a neutrino with high transverse energies and search for mass peaks in the eν transverse mass spectra. We also identify candidate events which contain a W boson decaying via W arrow e ν and at least two jets with transverse energy ET >= 20 GeV. The invariant mass spectra for the W + two jets and jet-jet combinations are searched for peaks. We obtain upper limits on σ cdot Br for new heavy charged vector boson production. *We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

    We present a search for leptoquark pairs decaying to τ+ τ- b bar b. The observed yield of τ+ τ- X events is consistent with Z → τ τ production; no evidence for leptoquarks is found. We use this result to place 95% confidence level bounds on the continuum cross section for scalar and vector leptoquark pairs, assuming BR(LQ → τ b) = 100%. We interpret the cross section bounds as lower limits on the leptoquark mass. In addition, we consider leptoquark production in technicolor models. In this context, the leptoquarks are technipions and may be pair-produced through a technirho resonance. We place bounds on the resonant production cross section as a function of technirho and technipion masses. *We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

    2005-01-01

    In the framework of the SPES project (Study for Production of Exotic Species), funded by Istituto Nazionale Fisica Nucleare (INFN) at the Laboratori Nazionali Legnaro (LNL) (Padua) for Radioactive Ion Beam (RIB) production, an R and D experiment of a charge breeder device, called BRIC (BReeding Ion Charge), is in progress at LNL. BRIC is an Electron Beam Ion Source (EBIS) type ion charge state breeder in which a radio frequency (RF) quadrupolar field has been superimposed in the trapped ion region to introduce a selective containment with the aim of increasing the wanted ion trapping efficiency. A code that studies the motion and the ion charge state evolution in the trap region of the BRIC device has been recently developed in the Bari INFN section. That code has the aim of showing if, in the presence of an axial magnetic field and electron beam space charge force, the RF quadrupole field can still give a selective ion containment in the EBIS trap region. The code, furthermore, should allow choosing the RF quadrupole parameters to optimize the ion charge containment efficiency. In this paper the main feature of the code, named BRICTEST, and the simulation test will be presented and shortly discussed

    Full Text Available Emilio Bajetta, Sara Pusceddu, Valentina Guadalupi, Monika Ducceschi, Luigi CelioMedical Oncology Unit 2, Fondazione IRCCS “Istituto Nazionale dei Tumori”, Milan, ItalyAbstract: Prevention of nausea and vomiting is the main goal of antiemetic treatment in cancer patients scheduled to receive chemotherapy. To prevent acute emesis, antiemetics should be administered just before chemotherapy and patients should be protected for up to 24 hours after chemotherapy initiation. The emetogenic potential of chemotherapeutic agents guides clinicians towards the most appropriate antiemetic prophylaxis. Current guidelines recommend the use of 5-HT3 receptor antagonist (RA either alone or in combination with dexamethasone and/or a neurokinin-1 RA both in the acute and delayed phases. The second-generation 5-HT3RA palonosetron exhibits a longer half-life and a higher binding affinity than older antagonists. Palonosetron has been approved by the FDA for the prevention of chemotherapy-induced nausea and vomiting (CINV in patients scheduled to receive either moderately (MEC or highly emetogenic chemotherapy (HEC and for the prevention of delayed CINV in patients receiving MEC. The present review will discuss the role of palonosetron in the prevention of acute CINV.Keywords: antiemetics, chemotherapy, nausea, vomiting, serotonin-receptor antagonists, palonosetron

    The predictive scale for mortality risk in patients with nonvariceal upper gastrointestinal bleeding (NVUGIB) proposed by Italy's PNED (Progetto Nazionale Emorragia Digestiva) group has not been validated in Latin America since its original publication. To compare the PNED system and the Rockall score as mortality predictors in patients hospitalized for NVUGIB. A multicenter, prospective, cross-sectional, analytic study was conducted that recruited patients diagnosed with nonvariceal upper gastrointestinal bleeding within the time frame of 2011 to 2015. Six Mexican hospital centers participated in the study. The Rockall and PNED system scores were calculated, classifying the patients as having mild, moderate, or severe disease. The association between mortality and risk was determined through the chi-square test and relative risk (RR) calculation. Statistical significance was set at a Pbleeding. According to the Rockall score, 46 patients had severe disease (23.2%), 5 of whom died, with a RR of 5.5 (CI 1.35-22.02, P=.006). In relation to the PNED, only 8 patients had severe disease (4%), 5 of whom died, with a RR of 38.7 (CI 11.4-137.3, P=.001). The PNED system was more selective for classifying a case as severe, but it had a greater predictive capacity for mortality, compared with the Rockall score.

    2003-01-01

    Full text: In order to investigate the influence of a low background radiation environment on the biochemical and biological responses of mammalian cells cultured in vitro, a cell culture laboratory has been set up at the Gran Sasso National Laboratory (LNGS) of the Istituto Nazionale di Fisica Nucleare (INFN), located under the Gran Sasso d'Italia mountain, where cosmic rays are reduced by a factor of 10 6 and neutrons by a factor of 10 3 respect to the outside environment. Chinese hamster V79 cells were grown in parallel for up to nine months at LNGS and at the Istituto Superiore di Sanita (ISS). At the LNGS the exposure due to radon was reduced by a factor of about 25 with respect to the ISS. The biological end points addressed concerned cells proliferation, the expression of enzymes specific for the reduction of superoxydes, mutation induction by gamma-rays at the hprt locus and apoptotic sensitivity. After 9 months of culture, the cells grown at the LNGS, compared to the cells grown at the ISS, exhibit: i) a significant increase of the cell density at confluence; ii) a significantly higher capacity to scavenge organic and inorganic hydroperoxydes but a reduced scavenging capacity towards superoxide anions; iii) an increase in both the basal hprt mutation frequency and the sensitivity to the mutagenic effect of gamma-rays. The cells grown at the LNGS also show greater apoptotic sensitivity at the third month of culture that is no longer detected after nine months. Overall, these data suggest that cell response to ionizing radiation may be more complex than that predicted by a linear relationship with the dose and are consistent with the occurrence of an adaptive response related to the background radiation. However, other possibilities cannot be excluded such as the selection, in the two cultures, of clones having different characteristics, independently of the different radiation background. Work is in progress to better elucidate this point

  17. Investigating source directivity for the 2012 Ml5.9 Emilia (Northern Italy) earthquake by jointly using High-rate GPS and Strong motion data

    2012-12-01

    On May, 20th 2012, the Ferrara and Modena provinces (Emilia Romagna, Northern Italy) were struck by a moderate magnitude earthquake (Ml 5.9). The focal mechanism is consistent with a ~E-W-striking thrust fault. The mainshock was recorded by 29 high-rate sampling (1-Hz) continuous GPS (HRGPS) stations belonging to scientific or commercial networks and by 55 strong motion (SM) stations belonging to INGV (Istituto Nazionale di Geofisica e Vulcanologia) and RAN (Rete Accelerometrica Nazionale) networks, respectively. The spatial distribution of both HRGPS and SM stations with respect to the mainshock location allows a satisfactory azimuthal coverage of the area. To investigate directivity effects during the mainshock occurrence, we analyze the spatial variation of the peak ground displacement (PGD) measured either for HRGPS or SM sites, using different methods. For each HRGPS and SM site, we rotated the horizontal time series to the azimuth direction and we estimated the GPS-related and the SM-related peak ground displacement (G-PGD and S-PGD, respectively) retrieved by transverse component. However, in contrast to GPS displacements, the double integration of the SM data can be affected by the presence of drifts and, thus, they have to be corrected by quasi-manual procedures. To more properly compare the G-PGDs to the S-PGDs, we used the response spectrum. A response spectrum is simply the response of a series of oscillators of varying natural frequency, that are forced into motion by the same input. The asymptotic value of the displacement response spectrum is the peak ground displacement. Thus, for each HRGPS and SM site, we computed the value of this asymptotic trend (G-PGDrs and S-PGDrs, respectively). This method allows simple automatic procedures. The consistency of the PGDs derived from HRGPS and SM is also evaluated for sites where the two instruments are collocated. The PGDs obtained by the two different methods and the two different data types suggest a

    Full Text Available A seguito della crisi economica che ha colpito l'Italia negli ultimi anni si è avuta una contrazione delle risorse economiche messe a disposizione delle biblioteche italiane, specialmente di quelle dipendenti dal MIBACT.  In tale contesto, la Biblioteca Nazionale Centrale di Firenze e l'agenzia bibliografica nazionale che da essa dipende hanno subito un ridimensionamento del loro prodotto, la Bibliografia Nazionale Italiana, condizionata dalla grave contrazione del numero degli addetti alla sua redazione. La ricerca di soluzioni per far fronte alla difficile situazione ha portato a due importanti decisioni che fanno perno sul concetto di natura di servizio pubblico e sul principio della cooperazione. La prima ha portato alla pubblicazione della Bibliografia Nazionale Italiana in forma libera e gratuita sul sito della Biblioteca Nazionale Centrale di Firenze, a decorrere dallo scorso 30 maggio, consentendo alla BNI di mettersi al passo con le principali bibliografie nazionali europee. La seconda consiste nell'avvio di un progetto collaborativo che, seppur confermando il coordinamento bibliografico, la gestione informatica ed il controllo redazionale finale alla Biblioteca Nazionale Centrale di Firenze, si basa sull'apporto di alcune biblioteche di poli SBN dotate di precise caratteristiche di copertura da deposito legale e di specializzazione disciplinare, dando vita ad una Bibliografia Nazionale Italiana cooperativa.

    2009-06-01

    Full Text Available In 2007 several events were organized to celebrate the fiftieth anniversary of the International Geophysical Year
    (IGY, 1957-1958. The celebrations will last until 2009 and are taking place within different contexts: the International
    Polar Year (IPY, the International Heliophysical Year (IHY, the electronic Geophysical Year (eGY
    and the International Year of Planet Earth (IYPE.
    IGY offered a very appropriate and timely occasion to undertake a series of coordinated observations of various
    geophysical phenomena all over the globe. Italy took part in the broad international effort stimulated by IGY. In
    fact, Italy participated in observations and studies in many of the proposed scientific areas, in particular Geomagnetism
    and Aeronomy. The Istituto Nazionale di Geofisica (ING started the installation of observatories,
    and updated and ensured continuous recording of geophysical observations. Geomagnetism, ionospheric
    physics, seismology, and other geophysical disciplines, were advanced. Although much of the work was undertaken
    in Italy, some attention was also devoted to other areas of the world, in particular Antarctica, where Italy
    participated in seismological observations. This paper gives a summary of the Geomagnetism and Ionospheric

    n this article I try to report at the best the events and the emotions I experienced, together with my colleagues, when I was a young researcher working at the Frascati Center of CNEN. In the middle of 70’s the high energy physics activities carried out in Frascati were transferred from CNEN to INFN (Istituto Nazionale Fisica Nucleare) and the personnel had the chance to chose to continue to work at the CNEN (obviously in a different research field) or to continue to work in high energy physics, but at the INFN. I decided to remain at the CNEN and, consequently, I had to change my research activity. I moved from the high energy accelerators research field to the lasers research field in which, at that time at the CNEN, a new interesting project on “uranium laser isotope separation” was just starting. This article is focused on the theoretical and experimental development activity, carried out in the years 70’s-80’s at the CNEN Frascati Center, on a quite particular kind of laser to be utilized in that project. In this laser the active medium is not made of atoms or molecules but is a beam of free electrons running along a spatially periodic magnetic structure: this laser is the “Free Electron Laser” [it

    The Selective Production of Exotic Species (SPES) project is an ISOL facility under construction at Istituto Nazionale di Fisica Nucleare–Laboratori Nationali di Legnaro (INFN-LNL). 1+ radioactive ions, produced and extracted from the target-ion-source system, will be charge bred to high charge states by an ECR charge breeder (SPES-CB): the project will adopt an upgraded version of the PHOENIX charge breeder, developed since about twenty years by the Laboratoire de Physique Subatomique et de Cosmologie (LPSC). The collaboration between LNL and LPSC started in 2010 with charge breeding experiments performed on the LPSC test bench and led, in June 2014, to the signature of a Research Collaboration Agreement for the delivery of a complete charge breeder and ancillaries, satisfying the SPES requirements. Important technological aspects were tackled during the construction phase, as, for example, beam purity issues, electrodes alignment, and vacuum sealing. This phase was completed in spring 2015, after which the qualification tests were carried out at LPSC on the 1+/q+ test stand. This paper describes the characteristics of the SPES-CB, with particular emphasis on the results obtained during the qualification tests: charge breeding of Ar, Xe, Rb, and Cs satisfied the SPES requirements for different intensities of the injected 1+ beam, showing very good performances, some of which are “best ever” for this device

    The experimental characterization of the neutron fields produced as parasitic effect in medical accelerators is assuming an increased importance for either the patient protection or the facility design aspects. Medical accelerators are diverse in terms of particle type (electrons or hadrons) and energy, but the radiation fields around them have in common (provided that a given threshold energy is reached) the presence of neutrons with energy span over several orders of magnitude. Due to the large variability of neutron energy, field or dosimetry measurements in these workplaces are very complex, and in general, cannot be performed with ready-to-use commercial instruments. In spite of its poor energy resolution, the Bonner Sphere Spectrometer (BSS) is the only instrument able to simultaneously determine all spectral components in such workplaces. The energy range of this instrument is limited to E o and 90 o with respect to the beam-line. Here the ERBSS of UAB (Universidad Autonoma de Barcelona-Grup de Fisica de les Radiacions) and INFN (Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali di Frascati) were exposed to characterize the 'forward' and 'sideward' proton-induced neutron fields. The use of two ERBSS characterized by different set of spheres, central detectors, and independently established and calibrated, is important for guaranteeing the robustness of the measured spectra and estimating their overall uncertainties.

    2016-01-01

    There is a very long tradition of studying nuclear structure and reactions at the Legnaro National Laboratories (LNL) of the Istituto Nazionale di Fisica Nucleare (Italian Institute of Nuclear Physics). The wide expertise acquired in building and running large germanium arrays has made the laboratories one of the most advanced research centers in γ -ray spectroscopy. The ’gamma group’ has been deeply involved in all the national and international developments of the last 20 years and is currently one of the major contributors to the AGATA project, the first (together with its American counterpart GRETINA) γ -detector array based on γ -ray tracking. This line of research is expected to be strongly boosted by the coming into operation of the SPES radioactive ion beam project, currently under construction at LNL. In this report, written on the occasion of the 40th anniversary of the Nobel prize awarded to Aage Bohr, Ben R Mottelson and Leo Rainwater and particularly focused on the physics of nuclear structure, we intend to summarize the different lines of research that have guided nuclear structure and reaction research at LNL in the last decades. The results achieved have paved the way for the present SPES facility, a new laboratories infrastructure producing and accelerating radioactive ion beams of fission fragments and other isotopes.

    At Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali del Sud (INFN-LNS), the development of intense ion and proton sources has been supported by a great deal of work on the modelling of microwave generated plasmas for many years. First, a stationary version of the particle-in-cell code was developed for plasma modelling starting from an iterative strategy adopted for the space charge dominated beam transport simulations. Electromagnetic properties of the plasma and full-waves simulations are now affordable for non-homogenous and non-isotropic magnetized plasma via "cold" approximation. The effects of Coulomb collisions on plasma particles dynamics was implemented with the Langevin formalism, instead of simply applying the Spitzer 90° collisions through a Monte Carlo technique. A wide database of different cross sections related to reactions occurring in a hydrogen plasma was implemented. The next step consists of merging such a variety of approaches for retrieving an "as-a-whole" picture of plasma dynamics in ion sources. The preliminary results will be summarized in the paper for a microwave discharge ion source designed for intense and high quality proton beams production, proton source for European Spallation Source project. Even if the realization of a predictive software including the complete processes involved in plasma formation is still rather far, a better comprehension of the source behavior is possible and so the simulations may support the optimization phase.

    The purpose of the Active Phasing Experiment, designed under the lead of ESO, is to validate wavefront control concepts for ELT class telescopes. This instrument includes an Active Segmented Mirror, located in a pupil image. It will be mounted at a Nasmyth focus of one of the Unit Telescopes of the ESO VLT. APE contains four different types of phasing sensors, which are developed by Istituto Nazionale di Astrofisica in Arcetri, Instituto Astrofisica Canarias, Laboratoire d'Astrophysique de Marseille and ESO. These phasing sensors can be compared simultaneously under identical optical and environmental conditions. All sensors receive telecentric F/15 beams with identical optical quality and intensity. Each phasing sensor can measure segmentation errors of the active segmented mirror and correct them in closed loop. The phasing process is supervised by an Internal Metrology system developed by FOGALE Nanotech and capable of measuring piston steps with an accuracy of a few nanometers. The Active Phasing Experiment is equipped with a turbulence generator to simulate atmospheric seeing between 0.45 and 0.85 arcsec in the laboratory. In addition, the Active Phasing Experiment is designed to control simultaneously with the phasing corrections the guiding and the active optics of one of the VLT Unit Telescopes. This activity is supported by the European Community (Framework Programme 6, ELT Design Study, contract No 011863).

    Several epidemiologic studies have shown that oral cancer develops among individuals with a prior diagnosis of an oral premalignant lesion. Canceration chance in these patients is 17%, with the greatest rate occuring in the second year of observation. Based on this data, since 1981, 92 leukoplakias have been treated by out-patient laser surgery at the Istituto Nazionale Tumori of Milano. The therapeutic technique was laser excision to obtain a specimen for histology. Two groups were distinguished according to the diagnostic procedure. Thirtythree lesions (December 1981 to December 1982) were operated on without preliminary histologic examination, on the basis of a simple clinical diagnosis. Since January 1983 all leukoplakias have been biopsied in a systematic way and those negative for cancer treated with laser. Histology of the specimen showed 5 squamous cell carcinomas (15%) in the group of patients who did not undergo preoperative biopsy. Postoperative histology showed malignancy in 6 of 59 (10.2%) cases in spite of negative preoperative biopsies. Speckledand erosive leukoplakias had the highest canceration rate. Three of 11 patients with cancer were treated by knife excision or interstitial needle implantation because of margins in tumoral tissue or because they were unvaluable for injury by heat. Results have been satisfactory, only 2 of 54 followed leukoplakias and none of cancers recurred during a 2 year follow-up

    Full Text Available A workshop on Operational earthquake forecasting and decision making was convened in Varenna, Italy, on June 8-11, 2014, under the sponsorship of the EU FP 7 REAKT (Strategies and tools for Real-time EArthquake risK reducTion project, the Seismic Hazard Center at the Istituto Nazionale di Geofisica e Vulcanologia (INGV, and the Southern California Earthquake Center (SCEC. The main goal was to survey the interdisciplinary issues of operational earthquake forecasting (OEF, including the problems that OEF raises for decision making and risk communication. The workshop was attended by 64 researchers from universities, research centers, and governmental institutions in 11 countries. Participants and the workshop agenda are listed in the appendix.The workshop comprised six topical sessions structured around three main themes: the science of operational earthquake forecasting, decision making in a low-probability environment, and communicating hazard and risk. Each topic was introduced by a moderator and surveyed by a few invited speakers, who were then empaneled for an open discussion. The presentations were followed by poster sessions. During a wrap-up session on the last day, the reporters for each topical session summarized the main points that they had gleaned from the talks and open discussions. This report attempts to distill this workshop record into a brief overview of the workshop themes and to describe the range of opinions expressed during the discussions.

  15. Optics development in Africa

    The case study of the Office of External Activities in Cape Coast, Ghana has turned out to be a successful story in promoting research and capacity building of young scientists. The total involvement of many organizations show how laudable the idea has been. This centre has come to serve as a place to solve scientific problems as well as problems of national interest. It is foreseen that its activities can be a means to congregate African scientists to solve common problems. I think the bold step taken by OEA and some organs of ICTP, Trieste, Italy, Lund Institute of Technology, Sweden and Istituto Nazionale di Ottica Applicata, Firenze, Italy has helped up and coming African scientists to come face to face with the challenges of Laser research. Such projects seem feasible and sustainable since experts in these areas can serve as contact persons in Africa to undertake common research using optical techniques. This project has made it possible to explore various areas in optics that can be used to solve problems peculiar to the continent. This ICAC programme in Cape Coast has been successful thanks to the cooperation of the organs of ICTP as well as various international organizations. It is hoped that scientists elsewhere will have the interest to collaborate with us in order to uplift the image of optics in the continent - Africa. (author)

    Mednet is the very broad-band seismic network installed by the Istituto Nazionale di Geofisica (ING) in countries of the mediterranean area, with a final goal of 12-15 stations and a spacing of about 1000 km between stations. The project started in 1987 and will be completed within 1992. Mednet is motivated both by research interest and by seismic hazard monitoring; it will allow to define the structure of the mediterranean region to a high detail, to study properties of the seismic source for intermediate and large events, and to apply this knowledge to procedures of civil protection. To reach its goals, the network has been designed following the highest technical standards: STS-1/VBB sensors, Quanterra 24 bits A/D converters with 140 dB dynamic range, real-time telemetry. Five sites are now operational in Italy (L'Aquila, Bardonecchia and Villasalto) and in northern african countries (Midelt, Morocco; Gafsa, Tunisia); other sites are under construction in Pakistan (Islamabad), Irak (Rutba) and Egypt (Kottamya), while locations are examined for stations in Greece, Jugoslavia and Algeria. The centre of the mednet network is the data center (MDC) in Rome; its tasks include data collection, verification, quality control, archivial and dissemination, monitoring of station performance, event detection, routine determination of source parameters. Data distribution will follow the guidelines set by FDSN, and will be coordinated with other international network projects

  18. Influence of the Cavity Length on the Behavior of Hybrid Fixed-Point Cells Constructed at INRIM

    Hybrid cells with double carbon/carbon sheets are used at the Istituto Nazionale di Ricerca Metrologica (INRIM) for the realization of both pure metal fixed points and high-temperature metal-carbon eutectic points. Cells for the Cu and Co-C fixed points have been prepared to be used in the high-temperature fixed-point project of the Comité Consultatif de Thermométrie. The results of the evaluation processes were not completely satisfactory for the INRIM cells because of their low transition temperatures with respect to the best cells, and of a rather large melting range for the Co-C cell. A new design of the cells was devised, and considerable improvements were achieved with respect to the transition temperature, and the plateau shape and duration. As for the Cu point, the duration of the freezing plateaux increased by more than 50 % and the freezing temperature increased by 18 mK. As for the Co-C point, the melting temperature, expressed in terms of the point of inflection of the melting curve, increased by about 70 mK. The melting range of the plateaux, expressed as a difference was reduced from about 180 mK to about 130 mK, with melting times increased by about 50 %, as a consequence of an improvement of flatness and run-off of the plateaux.

Diopside and wollastonite are actually two of the most common lapis lazuli-forming minerals. For this former part of the study, we analysed rocks of known provenance at the microbeam line of the LNL laboratories in Legnaro (PD) of the Istituto Nazionale di Fisica Nucleare (INFN).

It includes artworks made of lapis lazuli manufactured in the 16 th and 17 th centuries but there is not precise information about the provenance of the used raw material. Results on the artworks show, as expected, that the Chilean provenance of the material used for the analysed artworks has to be excluded. Lapis lazuli used for five of the analysed artworks can be ascribed to the Afghan quarry district, while one object cannot be attributed only on the base of diopside and wollastonite analysis

    The last decade of the evolution of radar was heavily influenced by the rapid increase in the information processing capabilities. Advances in solid state radio HF devices, digital technology, computing architectures and software offered the designers to develop very efficient radars. In designing modern radars the emphasis goes towards the simplification of the system hardware, reduction of overall power, which is compensated by coding and real time signal processing techniques. Radars are commonly employed in geophysical radio soundings like probing the ionosphere; stratosphere-mesosphere measurement, weather forecast, GPR and radio-glaciology etc. In the laboratorio di Geofisica Ambientale of the Istituto Nazionale di Geofisica e Vulcanologia (INGV), Rome, Italy, we developed two pulse compression radars. The first is a HF radar called AIS-INGV; Advanced Ionospheric Sounder designed both for the purpose of research and for routine service of the HF radio wave propagation forecast. The second is a VHF radar called GLACIORADAR, which will be substituting the high power envelope radar used by the Italian Glaciological group. This will be employed in studying the sub glacial structures of Antarctica, giving information about layering, the bed rock and sub glacial lakes if present. These are low power radars, which heavily rely on advanced hardware and powerful real time signal processing. Additional information is included in the original extended abstract.

  3. Tweeting Earthquakes using TensorFlow

    2016-12-01

    The use of social media is emerging as a powerful tool for disseminating trusted information about earthquakes. Since 2009, the Twitter account @INGVterremoti provides constant and timely details about M2+ seismic events detected by the Italian National Seismic Network, directly connected with the seismologists on duty at Istituto Nazionale di Geofisica e Vulcanologia (INGV). Currently, it updates more than 150,000 followers. Nevertheless, since it provides only the manual revision of seismic parameters, the timing (approximately between 10 and 20 minutes after an event) has started to be under evaluation. Undeniably, mobile internet, social network sites and Twitter in particular require a more rapid and "real-time" reaction. During the last 36 months, INGV tested the tweeting of the automatic detection of M3+ earthquakes, studying the reliability of the information both in term of seismological accuracy that from the point of view of communication and social research. A set of quality parameters (i.e. number of seismic stations, gap, relative error of the location) has been recognized to reduce false alarms and the uncertainty of the automatic detection. We present an experiment to further improve the reliability of this process using TensorFlow™ (an open source software library originally developed by researchers and engineers working on the Google Brain Team within Google's Machine Intelligence research organization).

  4. Search for Squarks and Gluinos Using Dileptons in p overline p Collisions at √s = 1.8 TeV

    1996-05-01

    Supersymmetric partners of the gluons (gluinos) and the quarks (squarks) can be produced in proton-antiproton collisions at √s = 1.8 TeV at the Fermilab Tevatron if kinematically allowed. Squarks and gluinos can decay via charginos and neutralinos, the supersymmetric partners of the gauge bosons, to final states containing leptons. In the case of gluino pair production, there is no charge correlation between the leptons from each decay. With most Standard Model processes yielding dileptons with opposite electric charge, this property may be exploited to discriminate signal from background. The analysis presented, searches for an excess of events containing a pair of same-sign isolated leptons, missing energy, and two jets.

    Synchrotron radiation is characterized by a very wide spectral emission from IR to X-ray wavelengths and a pulsed structure that is a function of the source time structure. In a storage ring, the typical temporal distance between two bunches, whose duration is a few hundreds of picoseconds, is on the nanosecond scale. Therefore, synchrotron radiation sources are a very powerful tools to perform time-resolved experiments that however need extremely fast detectors. Uncooled IR devices optimized for the mid-IR range with sub-nanosecond response time, are now available and can be used for fast detection of intense IR sources such as synchrotron radiation storage rings. We present here different measurements of the pulsed synchrotron radiation emission at DAΦNE (Double Annular Φ-factory for Nice Experiments), the collider of the Laboratori Nazionali of Frascati (LNF) of the Istituto Nazionale di Fisica Nucleare (INFN), performed with very fast uncooled infrared detectors with a time resolution of a few hundreds of picoseconds. We resolved the emission time structure of the electron bunches of the DAΦNE collider when it works in a normal condition for high energy physics experiments with both photovoltaic and photoconductive detectors. Such a technology should pave the way to new diagnostic methods in storage rings, monitoring also source instabilities and bunch dynamics

    This note presents a study meant to set out a national catalogue
    (C.S.N. of seismic events the epicentres of which are to be found in
    Italian territory (or nearby. The catalogue, that will start from the
    year 1450 B.C., could be used for various purpose employing modern
    technologies.
    The complete C.S.N, is made of three main parts, each of which can
    also have a separate life:
    1 An Analytical Catalogue which comprises the greater part of
    data and is the most complete;
    2 A Macroseismic Atlas that shows the macroseismic aspect of
    the most relevant events;
    3 A Macroseismic Catalogue that translates in numeric terms the
    Atlas.

    To these is added a comprehensive Bibliography subdivided into 24
    chapters each of which covers one of the 24 time periods into which the
    catalogue has been subdivided.
    The Analytical Catalogue besides giving the main parameters for each
    earthquake (date, epicentre, hypocentral depth, MCS scale intensity, raagnitudo,
    each with its own reliability index gives indications also on the
    following sideline data:
    1 epicentral location (meaning by this the geographic region and
    the eventual indication that the epicentre is to be found on a borderline
    touching more geographic regions, or in the sea, or on the coast, or othermise
    in the external band (see text;
    2 with a reference to the Atlas, the event is shown as having been
    dealt with also mocroseismic data and it will con be found, as such, in
    the Atlas and in the Macroseismic Catalogue;
    3 indications on the typology of the earthquake: i.e. whether it is an
    « isolated » earthquake, or a « seismic period » (and if so with the indication
    of the foreshock, main or aftershocks or of a swarm;
    4 the possibility of indicating up to 7 sets of information suitably
    chose among 40 additional notes regarding instrumental, geophysical,
    physical or sensorial information besides the possibility of notifying
    that the event had undergone specific studies or whether it is even to be
    considered either noth sure or else legendary;
    5 the possibility of indicating up to four bibliographical items, is to
    be considered as capital.
    The Macroseismic Atlas gives the isoseists of the more supported by
    documentary evidences earthquake, with the calculation of the relative
    areas, of the rays of the equivalent circles and of the rays of prevalent
    maximal and minimal propagation; these latter with the value of the
    azimuth measured from the geographical North passing through the
    macroseismic epicentre.
    The Macroseismic Catalogue reports numerically the macroseismic data
    of the event: analytical and macroseismic epicentre; analytical and macroseismic
    hypocentral depth, numerical values, in km., of the the three
    serie of indicated rays, up to isoseist of the 4th degree (MCS.

  7. Women’s Activism and Innovation in Education: the Role of the Unione Femminile Nazionale in Sicily for the Transformation of Italian Pedagogy at the Beginning of the Twentieth Century

    Full Text Available The beginning of the twentieth century represented a special occasion in the development of women’s movements as a vehicle for a new culture of education. The growing role of women’s associations in modern society found fertile ground in the increasing demand for childcare. In Italy such a process reflected a meaningful phenomenon of social transformation, which was linked to the ascent of the lower classes and to the progression of democratic values. In a region like Sicily, the appearance of local branches of the Unione Femminile Nazionale in some principal cities of the isle, such as Catania, from 1909 onwards represented a crucial opportunity not only for the social and cultural elevation of working-class children, but also for the introduction of new models of schooling and the experimentation of new methods in education, within the wider framework of a general renewal in the science of education of the time. The most representative witness and «learner» of these innovative approaches to education was Giuseppe Lombardo Radice, who was to «transfer» many aspects of his experience into the reform of the entire primary school system in Italy (1923 in line with the design of «active schooling». A survey of the experience of the Sicilian sections of the Unione provides not only a significant example of civilization processes promoted by women’s activism, but also a key to better understanding the wealth of resources involved in the construction of a modern pedagogy in Italy before the coming of Fascism.

  10. A reflection on the work of Gianni Bonadonna from the viewpoint of the global challenge of adolescents and young adults with cancer.

    Adolescents and young adults (AYAs - ages 15 to 39) constitute approximately 40% of the world's population and contribute an estimated one million new cases of cancer annually, the great majority in low- and middle-income countries (LMICs). In high-income countries (HICs) cancer is the commonest cause of disease-related death in AYAs, though overall 5-year survival rates now exceed 80%. A very different circumstance likely holds in LMICs, but accurate assessments are not readily available.Breast cancer accounts for 40% of tumours in female AYAs and this age group includes the peak incidence of Hodgkin lymphoma. The late Professor Gianni Bonadonna contributed importantly to improved survival in patients with these two diseases. Accordingly, he would be justifiably proud of the advances in AYA oncology that are being made in Italy, especially the impact of his colleagues at the Istituto Nazionale dei Tumori (INT). The initiatives of the Associazione Italiana Ematologia Pediatrica and the Società Italiana Adolescenti con Malattie Onco-ematologiche are particularly noteworthy, with the accomplishment of productive collaboration between paediatric and adult cancer care providers serving as a model for other countries to emulate.Exporting these advances can be successful through the vehicle of "twinning": establishing sustainable cooperation between institutions in HICs and partners in LMICs. Colleagues in Monza and at INT have been leaders in such programmes for decades. Cancer in AYAs remains a global challenge to which Gianni Bonadonna surely would have risen with enthusiasm and leadership while securing measurable achievements.

    Bilateral high frequency subthalamic stimulation has been reported to be effective in the treatment of Parkinson's disease and levodopa-induced dyskinesias. To analyze the results of this surgical procedure we critically reviewed 17 parkinsonian patients with advanced disease complicated by motor fluctuations and dyskinesias. Between January 1998 and June 1999 these 17 consecutive patients (age 48-68 years; illness duration 8-27 years) underwent bilateral stereotactically guided implantation of electrodes into the subthalamic nucleus in the Department of Neurosurgery of the Istituto Nazionale Neurologico "C. Besta." Parameters used for continuous high-frequency stimulation were: frequency 160 Hz, pulse width 90 microsec, mean amplitude 2.05 +/- 0.45 V. Parts II and III of the UPDRS were used to assess motor performance before and after operation by the neurologic team. The follow-up ranged between 6 and 18 months. At latest examination, mean UPDRS II and III scores had improved by 30% (on stimulation, off therapy) with mean 50% reduction in daily off time. Peak dyskinesias and early morning dystonias also improved in relation to therapy reduction. Side effects were persistent postoperative supranuclear oculomotor palsy and postural instability in one case, worsened off-medication hypophonia in three, and temporary nocturnal confusion episodes in three. Postoperative MRI revealed a clinically silent intracerebral haematoma in one case. One electrode required repositioning. Continuous high frequency STN stimulation is an effective treatment for advanced PD. A functionally useful and safe electrode placement can be performed without microrecording.

    The links between Stn DBS and advanced Parkinson disease, and between GPi DBS and dystonia are nearly universally accepted by the neurologists and neurosurgeons. Nevertheless, in some conditions, targets such as the ventral thalamus and the Zona Incerta may be considered to optimize the results and avoid the side effects. Positive and negative aspects of current DBS treatments justify the research of new targets, new stimulation programs and new hardware. Since 1993, at the Istituto Nazionale Neurologico "Carlo Besta" in Milan, 580 deep brain electrodes were implanted in 332 patients. 276 patients were affected by movement disorders. The DBS targets included Stn, GPi, Voa, Vop, Vim, CM-pf, cZi, IC. The long-term follow-up is reported and related to the chosen target. DBS gave a new therapeutic option to patients affected by severe movement disorders, and in some cases resolved life-threatening pathological conditions that would otherwise result in the death of the patient, such as in status dystonicus, and post-stroke hemiballismus. Nevertheless, the potential occurrence of severe complications still limit a wider use of DBS. At today, the use of DBS in severe movement disorders is strongly positive even if further investigations and studies are needed to unveil potential new applications, and to refine the selection criteria for the actual indications and targets. The experience of different targets may be useful to guide and tailor the target choice to the individual clinical condition.

    The following is an interim annual report. Dr. Smith is currently on an extended TDY to the Istituto di Fisica dello Spazio Interplanetario (IFSI) at the Consilio Nazionale delle Richerche (CNR) in Rome, Italy, where he has been working on a related NASA grant in support of analysis of Infrared Space Observatory (ISO) data on star formation in Ultra Luminous Infrared Galaxies and our galaxy. Work emphasizes development of metal mesh grids for use in spacecraft, and the design and fabrication of test elements by the Naval Research Laboratory, Washington D.C. Work has progressed well, but slowly, on that program due to the departure of a key engineer. NASA has been advised of the delay, and granted a no-cost extension, whereby SAO has authorized a delay in the final report from NRL. Nevertheless NRL has continued to make progress. Two papers have been submitted to refereed journals related to this program, and a new design for mesh operating in the 20-40 micron region has been developed. Meetings continue through the summer on these items. A new technical scientist has been made a job offer and hopefully will be on board NRL shortly, although most of the present grant work is already completed. A more complete report, with copies of the submitted papers, designs, and other measures of progress, will be submitted to NASA in September when Dr. Smith returns from his current TDY.

    This paper describes an innovative beam diagnostic and monitoring system composed of a position sensitive detector and a residual range detector, based on scintillating optical fiber and on an innovative read-out strategy and reconstruction algorithm. The position sensitive detector consists of four layers of pre-aligned and juxtaposed scintillating fibres arranged to form two identical overlying and orthogonal planes. The 500 μm square section fibres are optically coupled to two Silicon Photomultiplier arrays using a channel reduction system patented by the Istituto Nazionale di Fisica Nucleare. The residual range detector is a stack of sixty parallel layers of the same fibres used in the position detector, each of which is optically coupled to a channel of Silicon Photomultiplier array by wavelength shifting fibres. The sensitive area of the two detectors is 9 × 9 cm2. After being fully characterized at CATANA proton therapy facility, the performance of the prototypes was tested during last year also at TIFPA proton irradiation facility. The unique feature of these detectors is the possibility to work in imaging conditions (e.g. a particle at a time up to 106 particles per second) and in therapy conditions up to 109 particles per second. The combined use of the two detectors, in imaging conditions, as an example of application, allows the particle radiography of an object. In therapy conditions, in particular, the system measures the position, the profiles, the energy and the fluence of the beam.

    The digital divide affecting elderly patients may compromise the diffusion of telemedicine systems for this age segment. It might be that the difficulties in the passage from trials to the effective distribution of telemedicine systems are also due to the awareness of a personal digital divide in the target population. The analysis aims to estimate the number of people over the age of 50 years with potential cardiovascular problems able to access the Web. It made use of data from several sources (the Survey of Health, Ageing and Retirement in Europe and the Istituto Nazionale di Statistica Multiscopo Survey). Furthermore, with regard to Italy, the estimates obtained from official data were compared with those obtained in a survey investigating heart failure patients in Tuscany. In 2011, the percentage of people suffering from cardiovascular diseases and with Web access was 24% in Europe, with significant differences by country (ranging from 53% in Switzerland to below 20% in Italy, Spain, and Portugal). In Italy, however, the proportion of people with Web access increased from 2007 to 2011, and the survey in Tuscany showed that elderly people with limited information and communications technology skills overcame challenges and learned how to connect to the Web because they started to appreciate new technologies. The opportunity to use the Internet to monitor patients with chronic disease can serve as a challenge to reduce the digital divide gap and, furthermore, to increase their social and technological inclusion.

  17. ANNALS OF GEOPHYSICS: AD MAJORA

    2014-03-01

    Full Text Available Annals of Geophysics is a bimonthly international journal, which publishes scientific papers in the field of geophysics sensu lato. It derives from Annali di Geofisica, which commenced publication in January 1948 as a quarterly periodical devoted to general geophysics, seismology, earth magnetism, and atmospheric studies. The journal was published regularly for a quarter of a century until 1982 when it merged with the French journal Annales de Géophysique to become Annales Geophysicae under the aegis of the European Geophysical Society. In 1981, this journal ceased publication of the section on solid earth geophysics, ending the legacy of Annali di Geofisica. In 1993, the Istituto Nazionale di Geofisica (ING, founder of the journal, decided to resume publication of its own journal under the same name, Annali di Geofisica. To ensure continuity, the first volume of the new series was assigned the volume number XXXVI (following the last issue published in 1982. In 2002, with volume XLV, the name of the journal was translated into English to become Annals of Geophysics and in consequence the journal impact factor counter was restarted. Starting in 2010, in order to improve its status and better serve the science community, Annals of Geophysics has instituted a number of editorial changes including full electronic open access, freely accessible online, the possibility to comment on and discuss papers online, and a board of editors representing Asia and the Americas as well as Europe.

    This paper describes an innovative beam diagnostic and monitoring system composed of a position sensitive detector and a residual range detector, based on scintillating optical fiber and on an innovative read-out strategy and reconstruction algorithm. The position sensitive detector consists of four layers of pre-aligned and juxtaposed scintillating fibres arranged to form two identical overlying and orthogonal planes. The 500 μm square section fibres are optically coupled to two Silicon Photomultiplier arrays using a channel reduction system patented by the Istituto Nazionale di Fisica Nucleare. The residual range detector is a stack of sixty parallel layers of the same fibres used in the position detector, each of which is optically coupled to a channel of Silicon Photomultiplier array by wavelength shifting fibres. The sensitive area of the two detectors is 9 × 9 cm 2 . After being fully characterized at CATANA proton therapy facility, the performance of the prototypes was tested during last year also at TIFPA proton irradiation facility. The unique feature of these detectors is the possibility to work in imaging conditions (e.g. a particle at a time up to 10 6 particles per second) and in therapy conditions up to 10 9 particles per second. The combined use of the two detectors, in imaging conditions, as an example of application, allows the particle radiography of an object. In therapy conditions, in particular, the system measures the position, the profiles, the energy and the fluence of the beam.

    The prototype presented in this paper is based on GaAs pixel detectors read-out by the PCC/MEDIPIX I circuit. The active area of a sensor is about 1 cm 2 therefore to cover the typical irradiation field used in mammography (18x24 cm 2 ), 18 GaAs detection units have been organized in two staggered rows of nine chips each and moved by a stepper motor in the orthogonal direction. The system is integrated in a mammographic equipment which comprehends the X-ray tube, the bias and data acquisition systems and the PC-based control system. The prototype has been developed in the framework of the Integrated Mammographic Imaging (IMI) project, an industrial research activity aiming to develop innovative instrumentation for morphologic and functional imaging. The project has been supported by the Italian Ministry of Education, University and Research (MIUR) and by five Italian High Tech companies, Alenia Marconi Systems (AMS), CAEN, Gilardoni, LABEN and Poli.Hi.Tech., in collaboration with the universities of Ferrara, Roma 'La Sapienza', Pisa and the Istituto Nazionale di Fisica Nucleare (INFN). In this paper, we report on the electrical characterization and the first imaging test results of the digital mammographic system. To assess the imaging capability of such a detector we have built a phantom, which simulates the breast tissue with malignancies. The radiographs of the phantom, obtained by delivering an entrance dose of 4.8 mGy, have shown particulars with a measured contrast below 1%

    2009-01-01

    We describe an Italian database of strong ground motion recordings and databanks delineating conditions at the instrument sites and characteristics of the seismic sources. The strong motion database consists of 247 corrected recordings from 89 earthquakes and 101 recording stations. Uncorrected recordings were drawn from public web sites and processed on a record-by-record basis using a procedure utilized in the Next-Generation Attenuation (NGA) project to remove instrument resonances, minimize noise effects through low- and high-pass filtering, and baseline correction. The number of available uncorrected recordings was reduced by 52% (mostly because of s-triggers) to arrive at the 247 recordings in the database. The site databank includes for every recording site the surface geology, a measurement or estimate of average shear wave velocity in the upper 30 m (Vs30), and information on instrument housing. Of the 89 sites, 39 have on-site velocity measurements (17 of which were performed as part of this study using SASW techniques). For remaining sites, we estimate Vs30 based on measurements on similar geologic conditions where available. Where no local velocity measurements are available, correlations with surface geology are used. Source parameters are drawn from databanks maintained (and recently updated) by Istituto Nazionale di Geofisica e Vulcanologia and include hypocenter location and magnitude for small events (M< ??? 5.5) and finite source parameters for larger events. ?? 2009 A.S.

    In support of the European post-Kyoto policy, the GREENGRASS project will measure the net global warming potential resulting from the exchange of CO2, N2O and Twitch managed European grasslands and assess the European wide mitigation potential of key field and farm management scenarios. Long-term micrometeorological measurements at sites in a European wide network will be complemented by experimental assessment of the effects of management options bonnet fluxes. The results will be used to refine emission factors used in national inventories and to evaluate farm-level mitigation scenarios with respect to tenet global warming potential associated to grassland management. These evaluations will be conducted at the field and farm level, and by upscaling simulation results to the Europe scale.

    Full Text Available After moderate to strong earthquakes in Italy or in the surrounding areas, the Istituto Nazionale di Geofisica e Vulcanologia (INGV; National Institute for Geophysics and Volcanology activates a temporary seismic network infrastructure. This is devoted to integration with the Italian National Seismic Network (RSN [Delladio 2011] in the epicentral area, thus improving the localization of the aftershocks distribution after a mainshock. This infrastructure is composed of a stand-alone, locally recording part (Re.Mo. [Moretti et al. 2010] and a real-time telemetered part (Re.Mo.Tel. [Abruzzese et al. 2011a, 2011b] that can stream data to the acquisition centers in Rome and Grottaminarda. After the May 20, 2012, Ml 5.9 earthquake in the Emilia region (northern Italy, the temporary network was deployed in the epicentral area; in particular, 10 telemetered and 12 stand-alone stations were installed [Moretti et al. 2012, this volume]. Using the dedicated connection between the acquisition center in Rome and the Ancona acquisition sub-center [Cattaneo et al. 2011], the signals of the real-time telemetered stations were acquired also in this sub-center. These were used for preliminary quality control, by adopting the standard procedures in use here (see next paragraph, and Monachesi et al. [2011]. The main purpose of the present study is a first report on this quality check, which should be taken into account for the correct use of these data. […

    Full Text Available On May 20 and 29, 2012, two earthquakes of magnitudes 5.9 and 5.8 (Mw, respectively, and their aftershock sequences hit the central Po Plain (Italy, about 40 km north of Bologna. More than 2,000 sizable aftershocks were recorded by the Isti-tuto Nazionale di Geofisica e Vulcanologia (INGV; National Institute of Geophysics and Volcanology National Seismic Network (http://iside.rm.ingv.it/. The sequence was generated by pure compressional faulting over blind thrusts of the western Ferrara Arc, and it involved a 50-km-long stretch of this buried outer front of the northern Apennines. The focal mechanisms of the larger shocks agree with available structural data and with present-day tectonic stress indicators, which show locally a maximum horizontal stress oriented ca. N-S; i.e. oriented perpendicular to the main structural trends. Most of the sequence occurred between 1 km and 12 km in depth, above the local basal detachment of the outer thrust fronts of the northern Apennines. We measured the surface displacement patterns associated with the mainshocks and some of the larger aftershocks (some of which had Mw >5.0 by applying the Interferometric Synthetic Aperture Radar (InSAR technique to a pair of C-Band Radarsat-1 images. We then used the coseismic motions detected over the epicentral region as input information, to obtain the best-fit model fault for the two largest shocks. […

    At Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali del Sud (INFN-LNS), the development of intense ion and proton sources has been supported by a great deal of work on the modelling of microwave generated plasmas for many years. First, a stationary version of the particle-in-cell code was developed for plasma modelling starting from an iterative strategy adopted for the space charge dominated beam transport simulations. Electromagnetic properties of the plasma and full-waves simulations are now affordable for non-homogenous and non-isotropic magnetized plasma via “cold” approximation. The effects of Coulomb collisions on plasma particles dynamics was implemented with the Langevin formalism, instead of simply applying the Spitzer 90° collisions through a Monte Carlo technique. A wide database of different cross sections related to reactions occurring in a hydrogen plasma was implemented. The next step consists of merging such a variety of approaches for retrieving an “as-a-whole” picture of plasma dynamics in ion sources. The preliminary results will be summarized in the paper for a microwave discharge ion source designed for intense and high quality proton beams production, proton source for European Spallation Source project. Even if the realization of a predictive software including the complete processes involved in plasma formation is still rather far, a better comprehension of the source behavior is possible and so the simulations may support the optimization phase.

    We present adaptive optics images of the extreme red supergiant VY Canis Majoris in the Ks , L', and M bands (2.15-4.8 μm) made with LMIRCam on the Large Binocular Telescope. The peculiar "Southwest Clump" previously imaged from 1 to 2.2 μm appears prominently in all three filters. We find its brightness is due almost entirely to scattering, with the contribution of thermal emission limited to at most 25%. We model its brightness as optically thick scattering from silicate dust grains using typical size distributions. We find a lower limit mass for this single feature of 5 × 10-3 M ⊙ to 2.5 × 10-2 M ⊙ depending on the assumed gas-to-dust ratio. The presence of the Clump as a distinct feature with no apparent counterpart on the other side of the star is suggestive of an ejection event from a localized region of the star and is consistent with VY CMa's history of asymmetric high-mass-loss events.

    Full Text Available This article describes the ARGO Satellite Seismic Network (ARGO SSN as a reliable system for monitoring, collection, visualisation and analysis of seismic and geophysical low-frequency data, The satellite digital telemetry system is composed of peripheral geophysical stations, a centraI communications node (master sta- tion located in CentraI Italy, and a data collection and processing centre located at ING (Istituto Nazionale di Geofisica, Rome. The task of the peripheral stations is to digitalise and send via satellite the geophysical data collected by the various sensors to the master station. The master station receives the data and forwards them via satellite to the ING in Rome; it also performs alI the monitoring functions of satellite communications. At the data collection and processing centre of ING, the data are received and analysed in real time, the seismic events are identified and recorded, the low-frequency geophysical data are stored. In addition, the generaI sta- tus of the satellite network and of each peripheral station connected, is monitored. The procedure for analysjs of acquired seismic signals allows the automatic calculation of local magnitude and duration magnitude The communication and data exchange between the seismic networks of Greece, Spain and Italy is the fruit of a recent development in the field of technology of satellite transmission of ARGO SSN (project of European Community "Southern Europe Network for Analysis of Seismic Data"

    We report the discovery of a system of two super-Earths orbiting the moderately active K-dwarf HD 176986. This work is part of the RoPES RV program of G- and K-type stars, which combines radial velocities (RVs) from the HARPS and HARPS-N spectrographs to search for short-period terrestrial planets. HD 176986 b and c are super-Earth planets with masses of 5.74 and 9.18 M⊕, orbital periods of 6.49 and 16.82 days, and distances of 0.063 and 0.119 AU in orbits that are consistent with circular. The host star is a K2.5 dwarf, and despite its modest level of chromospheric activity (log10 (RHK' = -4.90 ± 0.04), it shows a complex activity pattern. Along with the discovery of the planets, we study the magnetic cycle and rotation of the star. HD 176986 proves to be suitable for testing the available RV analysis technique and further our understanding of stellar activity.

    Personnel monitoring provides the means to measure and record the radiation doses received by individual workers. The ionising radiation decree (230/95) set out the circumstances when the assessment and recording of person's exposure is legally required. Many employers issue dosemeters to staff even though there is no legal requirement to do so. This may be part of a quality assurance programme or as a reassurance measure. Dosemeter readings will serve to ensure compliance with legal dose limits and assure the employer that radiation exposure is as low as reasonably achievable. The ENEA (National Agency for New Technology, Energy and the Environment) IRP (Institute for Radiation Protection) individual monitoring service has been running for over 30 years. It offers personnel dosemeters which are based on its expertise and backed up by continual research and development. The report provides details of the dosemeters in use at IRP enable to decide which ones most suit the needs and shows IMS's organisation, customer and communications, dose reports form and administrative items. A short mention of future development will also be given.

    To investigate the clinical implication of performing pre-treatment dosimetry for 90 Y-microspheres liver radioembolization on 99m Tc-MAA SPECT images reconstructed without attenuation or scatter correction and quantified with the patient relative calibration methodology. Twenty-five patients treated with SIR-Spheres ® at Istituto Europeo di Oncologia and 31 patients treated with TheraSphere ® at Istituto Nazionale Tumori were considered. For each acquired 99m Tc-MAA SPECT, four reconstructions were performed: with attenuation and scatter correction (AC_SC), only attenuation (AC_NoSC), only scatter (NoAC_SC) and without corrections (NoAC_NoSC). Absorbed dose maps were calculated from the activity maps, quantified applying the patient relative calibration to the SPECT images. Whole Liver (WL) and Tumor (T) regions were drawn on CT images. Injected Liver (IL) region was defined including the voxels receiving absorbed dose >3.8 Gy/GBq. Whole Healthy Liver (WHL) and Healthy Injected Liver (HIL) regions were obtained as WHL = WL - T and HIL = IL - T. Average absorbed dose to WHL and HIL were calculated, and the injection activity was derived following each Institute's procedure. The values obtained from AC_NoSC, NoAC_SC and NoAC_NoSC images were compared to the reference value suggested by AC_SC images using Bland-Altman analysis and Wilcoxon paired test (5% significance threshold). Absorbed-dose maps were compared to the reference map (AC_SC) in global terms using the Voxel Normalized Mean Square Error (%VNMSE), and at voxel level by calculating for each voxel the normalized difference with the reference value. The uncertainty affecting absorbed dose at voxel level was accounted for in the comparison; to this purpose, the voxel counts fluctuation due to Poisson and reconstruction noise was estimated from SPECT images of a water phantom acquired and reconstructed as patient images. NoAC_SC images lead to activity prescriptions not significantly different from the

    Full Text Available In the present paper we describe the on-land field operations integrated in the TOMO-ETNA experiment carried out in June-November 2014 at Mt. Etna volcano and surrounding areas. This terrestrial campaign consists in the deployment of 90 short-period portable three-component seismic stations, 17 Broadband seismometers and the coordination with 133 permanent seismic station belonging to Italy’s Istituto Nazionale di Geofisica e Vulcanologia (INGV. This temporary seismic network recorded active and passive seismic sources. Active seismic sources were generated by an array of air-guns mounted in the Spanish oceanographic vessel “Sarmiento de Gamboa” with a power capacity of up to 5200 cubic inches. In total more than 26,000 shots were fired and more than 450 local and regional earthquakes were recorded. We describe the whole technical procedure followed to guarantee the success of this complex seismic experiment. We started with the description of the location of the potential safety places to deploy the portable network and the products derived from this search (a large document including full characterization of the sites, owners and indication of how to arrive to them. A full technical description of the seismometers and seismic sources is presented. We show how the portable seismic network was deployed, maintained and recovered in different stages. The large international collaboration of this experiment is reflected in the participation of more than 75 researchers, technicians and students from different institutions and countries in the on-land activities. The main objectives of the experiment were achieved with great success.

    Recently, a high efficiency regime of acceleration in laser plasmas has been discovered, allowing table top equipment to deliver doses of interest for radiotherapy with electron bunches of suitable kinetic energy. In view of an R&D program aimed to the realization of an innovative class of accelerators for medical uses, a radiobiological validation is needed. At the present time, the biological effects of electron bunches from the laser-driven electron accelerator are largely unknown. In radiobiology and radiotherapy, it is known that the early spatial distribution of energy deposition following ionizing radiation interactions with DNA molecule is crucial for the prediction of damages at cellular or tissue levels and during the clinical responses to this irradiation. The purpose of the present study is to evaluate the radio-biological effects obtained with electron bunches from a laser-driven electron accelerator compared with bunches coming from a IORT-dedicated medical Radio-frequency based linac's on human cells by the cytokinesis block micronucleus assay (CBMN). To this purpose a multidisciplinary team including radiotherapists, biologists, medical physicists, laser and plasma physicists is working at CNR Campus and University of Pisa. Dose on samples is delivered alternatively by the "laser-linac" operating at ILIL lab of Istituto Nazionale di Ottica and an RF-linac operating for IORT at Pisa S. Chiara Hospital. Experimental data are analyzed on the basis of suitable radiobiological models as well as with numerical simulation based on Monte Carlo codes. Possible collective effects are also considered in the case of ultrashort, ultradense bunches of ionizing radiation.

    VIRTIS-M is a visible-infrared (VIS-IR) image spectrometer designed for the Rosetta mission; it intends to provide detailed informations on the physical, chemical, and mineralogical nature of comets and asteroids. The in-flight performances of VIRTIS-M are expected to be influenced by various disturbances, like the initial strong vibrations of the rocket, the long duration of the experiment (from 2003 to 2010), as well as other possible environmental changes; therefore, an in-flight recalibration procedure is mandatory. Quite often in such kinds of missions, a light emission diode (LED) is employed to calibrate the on-board spectrometers by taking advantage of the relative small dimensions, stability, and hardness of these sources. VIRTIS-M is the first image spectrometer that will use a new generation of lamps for internal calibrations. These new lamps are characterized by a wide spectral range with a blackbody-like emission with an effective temperature of about (2400-2600 K), thereby covering the whole VIRTIS-M's spectral range (0.2-5 μm); i.e., they offer the possibility of a wider spectral calibration in comparison with the quasimonochromatic LED emission. A precise spectral calibration is achieved by adding special filters for visible and infrared ranges in front of the window source, containing many narrow absorption lines. In the present article, we describe the calibration and tests of some flight prototypes of these lamps (VIS and IR), realized by the Officine Galileo and calibrated by the Consiglio Nazionale delle Ricerche-Istituto di Astrofisica Spaziale e Fisica Cosmica

    To evaluate the incidence and risk factors of postsurgical site infections (SSIs) in elective neurosurgical procedures in patients treated with an ultrashort antibiotic protocol. In this consecutive series of 1747 patients treated with elective neurosurgery and ultrashort prophylactic antibiotic therapy at the Fondazione Istituto Nazionale Neurologico "Carlo Besta" in Milan, the rate of SSIs was 0.7% (13 patients). When only clean neurosurgery was considered, there were 11 such SSIs (1.52%) in 726 craniotomies and one SSI (0.15) in 663 spinal operations. The antibiotic protocol was prolonged in every case of external communication as cerebrospinal fluid leaks or external drainages. The infection rate of the whole series was low (0.72%), and a risk factor identified for SSIs in clean neurosurgery was longer surgery duration. The relative risk estimate was 12.6 for surgeries lasting 2 hours and 24.3 for surgeries lasting 3 or more hours. Patients aged older than 50 years had a lower risk of developing SSI with a relative risk of 0.23 when compared with patients aged younger than 50 years. The present series reports a low incidence of SSIs for elective neurosurgery, even for high-risk complex craniotomies performed for tumor removal. Given that an antibiotic protocol prolongation was used to pretreat any early signs of infection and external communication, the protocol was appropriate for the case mix. The two identified risk factors (surgical duration > 2 hours and middle-aged patients [16-50 yr]) may be indicators of other factors, such as the level of surgical complexity and poor neurological outcome.

    Surgery is still the standard treatment for desmoid-type fibromatosis (DF). Recently, the Institut Gustave Roussy (IGR), Villejuif, France, reported a series of patients treated with a front-line conservative approach (no surgery and no radiotherapy). The disease remained stable in more than half of patients. This study was designed to evaluate this approach on the natural history of the disease in a larger series of patients. A total of 142 patients presenting to the IGR or Istituto Nazionale Tumori (INT), Milan, Italy, were initially treated using a front-line deliberately conservative policy. Their progression-free survival (PFS) was observed and a multivariate analysis was performed for major clinical variables. Seventy-four patients presented with primary tumor, 68 with recurrence. Eighty-three patients received a "wait & see" policy (W&S), whereas 59 were initially offered medical therapy (MT), mainly hormonal therapy and chemotherapy. A family history of sporadic colorectal cancer was present in 8% of patients. The 5-year PFS was 49.9% for the W&S group and 58.6% for the medically treated patients (P = 0.3196). Similar results emerged for primary and recurrent DF. Multivariate analysis identified no clinical variables as independent predictors of PFS. In the event of progression, all patients were subsequently managed safely. A conservative policy could be a safe approach to primary and recurrent DF, which could avoid unnecessary morbidity from surgery and/or radiation therapy. Half of patients had medium-term stable disease after W&S or MT. A multidisciplinary, stepwise approach should be prospectively tested in DF.

    Full Text Available Un cinghiale selvatico femmina, di circa due anni di età, è stato trovato morto dai Servizi Veterinari a Pianola di Roio a L'Aquila, Provincia situata nella Regione Abruzzo nell'Italia centrale. La carcassa è stata conferita all'Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise "G. Caporale" di Teramo per l'esecuzione dell'esame autoptico. Dai linfonodi sotto-mandibolari di questo esemplare è stato isolato un ceppo di Brucella suis biovariante 2. Questa è la prima segnalazione d'isolamento di B. suis nella Regione Abruzzo. Diversi autori hanno accettato, in passato, l'ipotesi che B. suis biovariante 2 sia stata introdotta in Italia attraverso l'importazione di lepri provenienti dai paesi europei in cui l'infezione è endemica nelle popolazioni selvatiche. Questa considerazione ha portato le autorità italiane a rafforzare i controlli esistenti sulle lepri selvatiche importate a scopo di ripopolamento. Tuttavia, attualmente, non è in vigore alcuna disposizione (né lo è stata in passato per il controllo della brucellosi nei cinghiali movimentati, sia a livello nazionale che europeo. L'isolamento di B. suis biovariante 2 da cinghiali in altre Regioni italiane geograficamente distanti potrebbe suggerire che questa specie, piuttosto che le lepri importate, possa essere stata la fonte d'introduzione dell'infezione in tali aree. Le norme nazionali ed europee di gestione della brucellosi nella fauna selvatica dovrebbero essere indirizzate al controllo dello stato di salute dei cinghiali negli allevamenti prima delle movimentazioni o del rilascio, con l'obiettivo di prevenire la diffusione di questo patogeno in territori indenni.

    Using the 8.4 m Large Binocular Telescope, we observed six GRB afterglows from 2.8 hr to 30.8 days after the burst triggers to systematically probe the late-time behaviors of afterglows including jet breaks, flares, and supernova bumps. We detected five afterglows with Sloan r' magnitudes ranging from 23.0 to 26.3 mag. The depth of our observations allows us to extend the temporal baseline for measuring jet breaks by another decade in timescale. We detected two jet breaks and a third candidate, all of which are not detectable without deep, late-time optical observations. In the other three cases, we do not detect the jet breaks either because of contamination from the host galaxy light, the presence of a supernova bump, or the intrinsic faintness of the optical afterglow. This suggests that the basic picture that GRBs are collimated is still valid and that the apparent lack of Swift jet breaks is due to poorly sampled afterglow light curves, particularly at late times.

    On 29 December 2013, the Chaparrastique volcano in El Salvador, close to the town of San Miguel, erupted suddenly with explosive force, forming a column more than 9 km high and projecting ballistic projectiles as far as 3 km away. Pyroclastic density currents flowed to the north-northwest side of the volcano, while tephras were dispersed northwest and north-northeast. This sudden eruption prompted the local Ministry of Environment to request cooperation with Italian scientists in order to improve the monitoring of the volcano during this unrest. A joint force, made up of an Italian team from the Istituto Nazionale di Geofisica e Vulcanologia and a local team from the Ministerio de Medio Ambiente y Recursos Naturales, was organized to enhance the volcanological, geophysical and geochemical monitoring system to study the evolution of the phenomenon during the crisis. The joint team quickly installed a multiparametric mobile network comprising seismic, geodetic and geochemical sensors (designed to cover all the volcano flanks from the lowest to the highest possible altitudes) and a thermal camera. To simplify the logistics for a rapid installation and for security reasons, some sensors were colocated into multiparametric stations. Here, we describe the prompt design and installation of the geodetic monitoring network, the processing and results. The installation of a new ground deformation network can be considered an important result by itself, while the detection of some crucial deforming areas is very significant information, useful for dealing with future threats and for further studies on this poorly monitored volcano.

    A low frost-point generator (INRIM 03) operating at sub-atmospheric pressure has been designed and constructed at the Istituto Nazionale di Ricerca Metrologica (INRIM) as part of a calibration facility for upper-air sounding instruments. This new humidity generator covers the frost-point temperature range between  ‑99 °C and  ‑20 °C and works at any controlled pressure between 200 hPa and 1100 hPa, achieving a complete saturation of the carrier gas (nitrogen) in a single passage through a stainless steel isothermal saturator. The generated humid gas contains a water vapour amount fraction between 14  ×  10‑9 mol mol‑1 and 5  ×  10‑3 mol mol‑1. In this work the design of the generator is reported together with characterisation and performance evaluation tests. A preliminary validation of the INRIM 03 against one of the INRIM humidity standards in the common region is also included. Based on experimental test results, an initial uncertainty evaluation of the generated frost-point temperature, T fp, and water vapour amount fraction, x w, in the limited range down to  ‑75 °C at atmospheric pressure is reported. For the frost-point temperature, the uncertainty budget yields a total expanded uncertainty (k  =  2) of less than 0.028 °C, while for the mole fraction the budget yields a total expanded uncertainty of less than 10‑6 mol mol‑1.

    The prototype presented in this paper is based on GaAs pixel detectors read-out by the PCC/MEDIPIX I circuit. The active area of a sensor is about 1 cm{sup 2} therefore to cover the typical irradiation field used in mammography (18x24 cm{sup 2}), 18 GaAs detection units have been organized in two staggered rows of nine chips each and moved by a stepper motor in the orthogonal direction. The system is integrated in a mammographic equipment which comprehends the X-ray tube, the bias and data acquisition systems and the PC-based control system. The prototype has been developed in the framework of the Integrated Mammographic Imaging (IMI) project, an industrial research activity aiming to develop innovative instrumentation for morphologic and functional imaging. The project has been supported by the Italian Ministry of Education, University and Research (MIUR) and by five Italian High Tech companies, Alenia Marconi Systems (AMS), CAEN, Gilardoni, LABEN and Poli.Hi.Tech., in collaboration with the universities of Ferrara, Roma 'La Sapienza', Pisa and the Istituto Nazionale di Fisica Nucleare (INFN). In this paper, we report on the electrical characterization and the first imaging test results of the digital mammographic system. To assess the imaging capability of such a detector we have built a phantom, which simulates the breast tissue with malignancies. The radiographs of the phantom, obtained by delivering an entrance dose of 4.8 mGy, have shown particulars with a measured contrast below 1%.

    The epidemic-type aftershock sequences (ETAS) models have been experimentally used to forecast the space-time earthquake occurrence rate during the sequence that followed the 2009 L'Aquila earthquake and for the 2012 Emilia earthquake sequence. These forecasts represented the two first pioneering attempts to check the feasibility of providing operational earthquake forecasting (OEF) in Italy. After the 2009 L'Aquila earthquake the Italian Department of Civil Protection nominated an International Commission on Earthquake Forecasting (ICEF) for the development of the first official OEF in Italy that was implemented for testing purposes by the newly established "Centro di Pericolosità Sismica" (CPS, the seismic Hazard Center) at the Istituto Nazionale di Geofisica e Vulcanologia (INGV). According to the ICEF guidelines, the system is open, transparent, reproducible and testable. The scientific information delivered by OEF-Italy is shaped in different formats according to the interested stakeholders, such as scientists, national and regional authorities, and the general public. The communication to people is certainly the most challenging issue, and careful pilot tests are necessary to check the effectiveness of the communication strategy, before opening the information to the public. With regard to long-term time-dependent earthquake forecast, the application of a newly developed simulation algorithm to Calabria region provided typical features in time, space and magnitude behaviour of the seismicity, which can be compared with those of the real observations. These features include long-term pseudo-periodicity and clustering of strong earthquakes, and a realistic earthquake magnitude distribution departing from the Gutenberg-Richter distribution in the moderate and higher magnitude range.

    A multi-physical approach developed for the hydrodynamic characterization of porous media using hydrogeophysical information is presented. Several pumping tests were performed in the Hydrogeosite Laboratory, a controlled full-scale site designed and constructed at the CNR-IMAA (Consiglio Nazionale delle Ricerche - Istituto di Metodologia per l'Analisi Ambientale), in Marsico Nuovo (Basilicata Region, Southern Italy), in order to obtain an intermediate stage between laboratory experiments and field survey. The facility consists of a pool, used to study water infiltration processes, to simulate the space and time dynamics of subsurface contamination phenomena, to improve and to find new relationship between geophysical and hydrogeological parameters, to test and to calibrate new geophysical techniques and instruments. Therefore, the Hydrogeosite Laboratory has the advantage of carrying out controlled experiments, like in a flow cell or sandbox, but at field comparable scale. The data collected during the experiments have been used to estimate the saturated hydraulic conductivity ks [ms-1] using a coupled inversion model working in transient conditions, made up of the modified Richards equation describing the water flow in a variably saturated porous medium and the Poisson equation providing the self-potential ϕ [V], which naturally occurs at points of the soil surface owing to the presence of an electric field produced by the motion of underground electrolytic fluids through porous systems. The result obtained by this multi-physical numerical approach, which removes all the approximations adopted in previous works, makes a useful instrument for real heterogeneous aquifer characterization and for predictive analysis of its behavior.

    Full Text Available Domenica Lorusso, Elisa Tripodi, Giuseppa Maltese, Stefano Lepori, Ilaria Sabatucci, Giorgio Bogani, Francesco Raspagliesi Gynecologic Oncology Unit, Fondazione IRCCS, Istituto Nazionale dei Tumori, Milan, Italy Abstract: Epithelial ovarian cancer is the sixth most common cancer among women worldwide and the first cause of death among gynecological malignancies. Most of the patients present recurrent disease and unfortunately cannot be cured. The unsatisfactory results obtained with salvage chemotherapy have elicited investigators to search for novel biological agents capable of achieving a better control of the disease. In the setting of homologous recombination deficiency, the DNA errors that occur cannot be accurately repaired, and the treatment with poly(ADP-ribose polymerase (PARP inhibition results in definitive cell death in a process called synthetic lethality. As a result of two positive clinical trials, Olaparib was approved in 2014 by U.S. Food and Drug Administration and European Medicines Agency as the first-in-class PARP inhibitor. Olaparib is effective and well tolerated in homologous recombination deficient patients. Several studies with Olaparib have been conducted in the recurrent setting either as maintenance in platinum-responsive patients or as a single agent. Ongoing trials are focused on the use of olaparib as maintenance in the first-line ovarian cancer setting alone or in combination with antiangiogenic agents. Future perspectives will probably investigate the association of olaparib with novel agents as check-point inhibitors and PI3K-AKT inhibitors. The PARP inhibitor era is just at the beginning.

    Full Text Available In Italia il panorama degli strumenti di ricerca archivistica on-line è in continua espansione. Esso è caratterizzato da una accentuata multiformità redazionale e scientifica, segnato da articolate strategie di pubblicazione ed è costituito sia dall’insieme di dati pregressi confluiti nel web, sia da strumenti di più recente generazione. In mancanza del SAN (Sistema Archivistico Nazionale, non ancora ultimato, i punti di riferimento del sistema sono rappresentati dalla Guida Generale, dal  SIAS (Sistema Informativo degli Archivi di Stato e dal SIUSA (Sistema Informativo Unificato per le Soprintendenze Archivistiche. Inoltre, i singoli archivi di stato hanno progetti indipendenti di pubblicazione on-line dei propri strumenti, attraverso formati come il PDF, l'HTML o l'XML/EAD. In quest'ambito, va segnalata un'iniziativa dell’ICAR (Istituto Centrale per gli ARchivi, il quale ha pubblicato una ricognizione degli inventari realizzati da ogni Archivio e già disponibili online su SIAS e sui siti degli Istituti archivistici. Per quanto riguarda il SIUSA, esso offre, in collaborazione con progetti regionali, una vasta gamma di inventari, di cui due validi esempi sono costituiti dal progetto Rinasco in Lazio e dal .DOC in Umbria. Infine, vi sono i sistemi informativi tematici, come Archivi del Novecento, progetto volto a costituire una rete di archivi per la storia italiana. L'offerta è quindi molto vasta, ma al fine di un esaustivo controllo di una realtà così complessa, è necessaria la strutturazione di un sistema federato di risorse locali o tematiche interoperabili e compatibile con SIUSA e/o con il nascente SAN.

    Full Text Available We collected teleseismic waveforms from a digital microseismic network deployed by the Istituto Nazionale di Geofisica (ING in collaboration with the U.S. Geological Survey (USGS, on the Alban Hills Quaternary volcano during the 1989-1990 seismic swann. About 50 events were recorded by the network, 30 of them by at least 4 stations. We analysed the data in order to image crustal heterogeneities beneath the volcano. The results show large delay time residuals up to - 1 second for stations located on the volcano with respect to station CP9 of the National Seismic Network located about 20 km to the east, on the Apennines. This suggests that the whole area overlies a broad low-velocity region. Although the ray coverage is not very dense, we model the gross seismic structure beneath the volcano by inverting the teleseismic relative residuals with the ACH technique. The main features detected by tbc inversion are a low-velocity zone beneath the southwestern fiank of tbc volcano, and a high-velocity region beneath the center. The depth extension of these anomalous zones ranges between 5 and 16 km. The correspondence between the low-velocity region and the most recent activity of the volcano (- 0.027 Ma leads us to infer the presence of a still hot magmatic body in the crust beneath the southwestern side of the volcano, whereas the central part overlies the older and colder high-velocity volcanic roots related to the previous central activity (0.7 to 0.3 Ma.

    Full Text Available The TOMO-ETNA experiment was planned in order to obtain a detailed geological and structural model of the continental and oceanic crust beneath Mt. Etna volcano and northeastern Sicily up to the Aeolian Islands (southern Italy, by integrating data from active and passive refraction and reflection seismic methodologies, magnetic and gravity surveys. This paper focuses on the marine activities performed within the experiment, which have been carried out in the Ionian and Tyrrhenian Seas, during three multidisciplinary oceanographic cruises, involving three research vessels (“Sarmiento de Gamboa”, “Galatea” and “Aegaeo” belonging to different countries and institutions. During the offshore surveys about 9700 air-gun shots were produced to achieve a high-resolution seismic tomography through the wide-angle seismic refraction method, covering a total of nearly 2650 km of shooting tracks. To register ground motion, 27 ocean bottom seismometers were deployed, extending the inland seismic permanent network of the Istituto Nazionale di Geofisica e Vulcanologia and a temporary network installed for the experiment. A total of 1410 km of multi-channel seismic reflection profiles were acquired to image the subsurface of the area and to achieve a 2D velocity model for each profile. Multibeam sonar and sub bottom profiler data were also collected. Moreover, a total of 2020 km of magnetic and 680 km of gravity track lines were acquired to compile magnetic and gravity anomaly maps offshore Mt. Etna volcano. Here, high-resolution images of the seafloor, as well as sediment and rock samples, were also collected using a remotely operated vehicle.

  17. Educational strategies to reduce risk: a choice of social responsibility

    Full Text Available This study develops the critical reflections of the activities for information, training and education that have been conducted by a group of researchers of the Istituto Nazionale di Geofisica e Vulcanologia in recent years. In particular, from an epistemological point of view, our analysis involves: (i science outreach, the link between science and the world; (ii science teaching and its role in the contact between science and schools; and (iii risk education, seen as a process that can develop a culture of risk in relation to the territory in which we live. These issues are critically analyzed on the basis of experience gained since 1995. The educational methodologies tested in ‘peacetime’ (in the absence of seismic events with the EDURISK Project are compared with those experienced during an emergency in Abruzzo, Italy. Today, we increasingly refer to prevention as the primary strategy of defense against risk. However, very often the responsibility of prevention falls on others, such as the government, institutions and/or local authorities. The citizens then perceive themselves as powerless against the inevitability of natural events, and they refer to these ‘rulers’ for the implementation of effective prevention policies. So, as researchers, what are the most effective actions we can take to influence risk reduction and to motivate the choices of the people? Must the effectiveness of our interventions be based on scientific information or on specific training, or must it be reached through the development of values, actions and awareness? Must our interventions be oriented and developed to inform, to train or to educate?

  18. DUSTER: collection of meteoric CaO and carbon smoke particles in the upper stratosphere .

    Della Corte, V.; Rietmeijer, F. J. M.; Rotundi, A.; Ferrari, M.; Palumbo, P.

    Nanometer- to micrometer-size particles present in the upper stratosphere are a mixture of terrestrial and extra-terrestrial origins. They can be extraterrestrial particles condensed after meteor ablation. Meteoric dust in bolides is occasionally deposited into the lower stratosphere around 20 km altitude. Nanometer CaO and pure carbon smoke particles were collected at 38 km altitude in the upper stratosphere in the Arctic during June 2008 using DUSTER (Dust in the Upper Stratosphere Tracking Experiment and Retrieval), a balloon-borne instrument for the non-destructive collection of solid particles between 200 nm to 40 microns. We report the collection of micron sized CaCO_3 (calcite) grains. Their morphologies show evidence of melting and condensation after vaporization suggest at temperatures of approximately 3500 K. The formation environment of the collected grains was probably a dense dust cloud formed by the disintegration of a carbonaceous meteoroid during deceleration in the Earth� atmosphere. For the first time, DUSTER collected meteor ablation products that were presumably associated with the disintegration of a bolide crossing the Earth's atmosphere. The collected mostly CaO and pure carbon nanoparticles from the debris cloud of a fireball, included: 1) intact fragments; 2) quenched melted grains; and 3) vapor phase condensation products. The DUSTER project was funded by the Italian Space Agency (ASI), PRIN2008/MIUR (Ministero dell'Istruzione dell'Universitá e della Ricerca), PNRA 2013(Piano Nazionale Ricerca Antartide).

The project is funded under the Information Society Technologies (IST) thematic programme of the European Commission's Fifth Framework. EGSO started in March 2002 and will last until March 2005. The project is categorized as a computer science effort. Evidently, a fair amount of issues it addresses are general to grid projects. Nevertheless, EGSO is also of benefit to the application domains, including solar physics, space weather, climate physics and astrophysics. With EGSO, researchers as well as the general public can access and combine solar data from distributed archives in an integrated virtual solar resource. Users express queries based on various search parameters. The search possibilities of EGSO extend the search possibilities of traditional data access systems. For instance, users can formulate a query to search for simultaneous observations of a specific solar event in a given number of wavelengths. In other words, users can search for observations on the basis of events and phenomena, rather than just time and location. The software architecture consists of three collaborating components: a consumer, a broker and a provider. The first component, the consumer, organizes the end user interaction and controls requests

    Full Text Available L'Etiopia ha sempre beneficiato di un’attenzione internazionale in quanto patria di un’eccellente tradizione gastronomica. Per quanto vi siano pietanze regionali diffuse in gran parte del Paese, vi è anche una cucina nazionale distinta. Ad elevare lo status di questa cucina nazionale ha contribuito la crescente popolarità di una sua pietanza particolarmente piccante conosciuta come wäṭ, che ha ora notorietà internazionale grazie al turismo e ai ristoranti etiopici in Europa e Nord-America. Gli Etiopi non hanno mai dubitato dello status elevato della loro alimentazione, ma non c’è ancora un autentico e compiuto testo di ricette etiopiche che promuova le pietanze del Paese. Per quanto la loro cucina si diffonda in più continenti, lo studio dell'alimentazione etiopica è agli inizi senza che si registrino apporti significativi che contribuiscano a una migliore conoscenza scientifica. Questo articolo esamina alcuni dei processi che sono implicati nell'alimentazione etiopica come cucina nazionale e internazionale, rievocando le radici storiche della sua tradizione gastronomica e i fattori che ne influenzano lo sviluppo come cucina trans-nazionale"

    Full Text Available L'Area Faunistica del Camoscio appenninico di Lama dei Peligni (CH nel Parco Nazionale della Majella è stata istituita nel 1990 con lo scopo principale di fungere da serbatoio di animali da utilizzare per operazioni di rinforzo della popolazione di Camosci in natura. Inoltre è stata ed è un notevole strumento per sensibilizzare la popolazione ed il pubblico alla conservazione della specie nonché una forte attrazione turistica per l'intera Valle dell'Aventino nel Parco Nazionale della Majella. L'Area Faunistica è ubicata nei pressi del centro abitato di Lama dei Peligni (CH sul versante Orientale della Majella ad un'altitudine che va dai 750 agli 850 m s.l.m. ed ha un'astensione complessiva di 4,2 ettari. Nel corso degli anni è stato necessario suddividere il recinto in 4 subrecinti per poter disporre di spazi separati utili per la gestione sanitaria del nucleo di animali ospitati. Inizialmente la responsabilità tecnica amministrativa è stata curata dal Parco Nazionale d'Abruzzo in collaborazione con il WWF Italia, successivamente è stata curata dalla Riserva Regionale "Majella Orientale" per passare dal 2000 all'Ente Parco Nazionale della Majella. L'area faunistica di Lama dei Peligni è stata attivata con l'immissione di un maschio prelevato in natura dalla popolazione della Val di Rose nel Parco Nazionale d'Abruzzo, Lazio e Molise e 5 femmine provenienti dal'Area Faunistica di Bisegna nel medesimo Parco. Nel periodo dal 1990 al 2002 sono nati 37 camosci e ne sono deceduti 20. Inoltre si sono verificati 14 rientri di animali provenienti dalla popolazione in natura e dall'Area Faunistica sono stati reimmessi 25 capi sul massiccio della Majella. L'Area di Lama dei Peligni ha consentito l'attivazione di un'ulteriore Area Faunistica nel Parco Nazionale del Gran Sasso Monti della Laga fornendo 1 femmina. Lo scopo principale del presente lavoro è di analizzare criticamente i dati raccolti in un database e di individuare un protocollo di

Despite this prevalence, such patients are often excluded from randomized trials or represent a minority of enrolled patients. Moreover, the criteria for establishing benefit or side effects of treatment strategies in this population are uncertain and not well recognized. Bevacizumab improves the outcome of mCRC when used in combination with standard first-line and second-line chemotherapy and beyond the first disease progression when given with a chemotherapy backbone different from that used in the precedent line. The particular toxicity profile of this antiangiogenesis agent (in particular hypertension, thromboembolic events, hemorrhage, and renal failure may discourage its use in elderly patients with comorbidities. Data from subgroup analyses of randomized trials and the results of recent cohort studies suggest a significant benefit from the addition of bevacizumab to standard chemotherapy for elderly patients comparable with that observed in younger patients, except for the increased risk for thromboembolic events. Age alone should not be a barrier to use of bevacizumab, and further research with a more complete geriatric assessment should investigate the role of bevacizumab in elderly patients with mCRC to avoid undertreatment of this patient population due to a ­historical conservative approach.

    The experimental characterization of the neutron fields produced as parasitic effect in medical accelerators is assuming an increased importance for either the patient protection or the facility design aspects. Medical accelerators are diverse in terms of particle type (electrons or hadrons) and energy, but the radiation fields around them have in common (provided that a given threshold energy is reached) the presence of neutrons with energy span over several orders of magnitude. Due to the large variability of neutron energy, field or dosimetry measurements in these workplaces are very complex, and in general, cannot be performed with ready-to-use commercial instruments. In spite of its poor energy resolution, the Bonner Sphere Spectrometer (BSS) is the only instrument able to simultaneously determine all spectral components in such workplaces. The energy range of this instrument is limited to ECATANA) of INFN—LNS (Laboratori Nazionali del Sud), where a proton beam routinely used for ophthalmic cancer treatments is available. The 62 MeV beam was directed towards a PMMA phantom, simulating the patient, and two neutron measurement points were established at 0° and 90° with respect to the beam-line. Here the ERBSS of UAB (Universidad Autónoma de Barcelona— Grup de Física de les Radiacions) and INFN (Istituto Nazionale di Fisica Nucleare—Laboratori Nazionali di Frascati) were exposed to characterize the "forward" and "sideward" proton-induced neutron fields. The use of two ERBSS characterized by different set of spheres, central detectors, and independently established and calibrated, is important for guaranteeing the robustness of the measured spectra and estimating their overall uncertainties.

    Full Text Available In the Sicily Channel, volcanic activity has been concentrated mainly on the Pantelleria and Linosa islands, while minor submarine volcanism took place in the Adventure, Graham and Nameless banks. The volcanic activity spanned mostly during Plio-Pleistocene, however, historical submarine eruptions occurred in 1831 on the Graham Bank and in 1891 offshore Pantelleria Island. On the Graham Bank, 25 miles SW of Sciacca, the 1831 eruption formed the short-lived Ferdinandea Island that represents the only Italian volcano active in historical times currently almost completely unknown and not yet monitored. Moreover, most of the Sicily Channel seismicity is concentrated along a broad NS belt extending from the Graham Bank to Lampedusa Island. In 2012, the Istituto Nazionale di Geofisica e Vulcanologia (INGV carried out a multidisciplinary oceanographic cruise, named “Ferdinandea 2012”, the preliminary results of which represent the aim of this paper. The cruise goal was the mapping of the morpho-structural features of some submarine volcanic centres located in the northwestern side of the Sicily Channel and the temporary recording of their seismic and degassing activity. During the cruise, three OBS/Hs (ocean bottom seismometer with hydrophone were deployed near the Graham, Nerita and Terribile submarine banks. During the following 9 months they have recorded several seismo-acoustic signals produced by both tectonic and volcanic sources. A high-resolution bathymetric survey was achieved on the Graham Bank and on the surrounding submarine volcanic centres. A widespread and voluminous gas bubbles emission was observed by both multibeam sonar echoes and a ROV (remotely operated vehicle along the NW side of the Graham Bank, where gas and seafloor samples were also collected.

    We present deep observations of a z = 1.4 massive, star-forming galaxy (SFG) in molecular and ionized gas at comparable spatial resolution (CO 3–2, NOrthern Extended Millimeter Array (NOEMA); Hα, Large Binocular Telescope (LBT)). The kinematic tracers agree well, indicating that both gas phases are subject to the same gravitational potential and physical processes affecting the gas dynamics. We combine the one-dimensional velocity and velocity dispersion profiles in CO and Hα to forward-model the galaxy in a Bayesian framework, combining a thick exponential disk, a bulge, and a dark matter halo. We determine the dynamical support due to baryons and dark matter, and find a dark matter fraction within one effective radius of {f}DM}(≤slant {R}e)={0.18}-0.04+0.06. Our result strengthens the evidence for strong baryon-dominance on galactic scales of massive z ∼ 1–3 SFGs recently found based on ionized gas kinematics alone. Based on observations carried out with the IRAM Interferometer NOEMA. IRAM is supported by INSU/CNRS (France), MPG (Germany), and IGN (Spain). Based on observations carried out with the LBT.

    Full Text Available On May 20, 2012, at 02:03 UTC, a moderate earthquake of local magnitude, Ml 5.9 started a seismic sequence in the central Po Plain of northern Italy The mainshock occurred in an area where seismicity of comparable magnitude has neither been recorded nor reported in the historical record over the last 1,000 years. The aftershock sequence evolved rapidly near the epicenter, with diminishing magnitudes until May 29, 2012, when at 07:00 UTC a large earthquake of Ml 5.8 occurred 12 km WSW of the mainshock, starting a new seismic sequence in the western area; a total of seven earthquakes with Ml >5 occurred in the area between May 20 and June 3, 2012. Immediately after the mainshock, the Italian Department of Civil Protection requested the Italian Space Agency to activate the Constellation of Small Satellites for Mediterranean Basin Observation (COSMO-SkyMed to provide Interferometric Synthetic Aperture Radar (InSAR coverage of the area. COSMO-SkyMed consists of four satellites in a 16-day repeat-pass cycle, with each carrying the same SAR payload. In the current orbital configuration, within each 16-day cycle, image pairs with temporal baselines of 1, 3, 4 and 8 days can be formed from the images acquired by the four different sensors. Combined with the availability of a wide range of electronically steered antenna beams with incidence angles ranging from about 16˚ to 50˚ at near-range, this capability allows trade-offs between temporal and spatial coverage to be exploited during acquisition planning. A joint team involving the Istituto Nazionale di Geofisica e Vulcanologia (INGV and the Istituto per il Rilevamento Elettromagnetico dell'Ambiente (IREA-CNR was activated to generate InSAR-based scientific products to support the emergency management. In this framework, the ASI and DPC requested that INGV activated the Space-based Monitoring System for Seismic Risk Management (SIGRIS. SIGRIS consists of a hardware/software infrastructure that is

    Many outreach events have been proposed by the scientific community to celebrate the Centenary of the January 13, 1915 earthquake, that devastated the Marsica territory, located in Central Apennines. The Laboratorio Divulgazione Scientifica e Attività Museali of the Istituto Nazionale di Geofisica e Vulcanologia (INGV's Laboratory for Outreach and Museum Activities) in Rome, has realised an interactive exhibition in the Castello Piccolomini, Celano (AQ), to retrace the many aspects of the earthquake disaster, in a region such as Abruzzo affected by several destructive earthquakes during its history. The initiatives represent an ideal opportunity for the development of new programs of communication and training on seismic risk and to spread the culture of prevention. The INGV is accredited with the Servizio Civile Nazionale (National Civic Service) and volunteers are involved in the project "Science and Outreach: a comprehensive approach to the divulgation of knowledge of Earth Sciences" starting in 2014. In this contest, volunteers had the opportunity to fully contribute to the exhibition, in particular, promoting and realising two panels concerning the social and environmental consequences of the Marsica earthquake. Describing the serious consequences of the earthquake, we may raise awareness about natural hazards and about the only effective action for earthquake defense: building with anti seismic criteria. After studies and researches conducted in libraries and via web, two themes have been developped: the serious problem of orphans and the difficult reconstruction. Heavy snowfalls and the presence of wolves coming from the high and wild surrounding mountains complicated the scenario and decelerated the rescue of the affected populations. It is important to underline that the earthquake was not the only devastating event in the country in 1915; another drammatic event was, in fact, the First World War. Whole families died and the still alive infants and

    fine della valutazione della dose ricevuta dalla popolazione itlaiana a seguito dell'esposizione alle radiazioni derivanti dai radionuclidi presenti nell'ambiente. Le Reti Nazionali consistono in un insieme di punti di osservazione localizzati sul territorio nazionale definiti per analizzare l'andamento spazio-temporale delle concentrazioni dei radioelementi in matrici ambientali ed alimentari dei diversi comparti ambientali interessati dalla diffusione della radioattivita' e dal trasferimento di questa all'uomo. Le Reti sono progettate in modo da permettere anche la rilevazione di fenomeni di accumulo dei radionuclidi a lunga vita media nell'ambiente. Le frequenze di campionamento delle matrici ambientali previste nelle diverse reti, tengono conto dei tempi di accumulo della radioattivita' nei vari comparti ambientali. Il Decreto Legislativo N. 230 del 1995 affida all'ANPA il coordinamento tecnico delle Reti Nazionali. In questo ambito l'ANPA e' tenuta alla raccolta e all'analisi dei dati di radioattivita' ambientale provenienti dalle Istituzioni partecipanti alle Reti Nazionali, assicurandone la diffusione periodica tramite appositi rapporti annuali. In ottemperanza di accordi internazionali, gli stessi dati sono trasmessi anche alla Commissione Europea. All'ANPA sono inoltre affidate attivita per la normalizzazione dei metodi di prelievo e di misura delle matrici ambientali e alimentari. Per garantire l'affidabilita' generale dei dati pubblicati e delle valutazioni conseguenti e permettere agli Istituti, Enti ed Organismi che partecipano alle Reti Nazionali il raggiungimento di livelli di accuratezza e di affidabilita adeguati agli scopi del controllo ambientale, i laboratori responsabili dei prelievi e delle misure e facenti parte delle Reti Nazionali, partecipano sistematicamente ad un programma di affidabilita' organizzato dall'ANPA in collaborazione con l'Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti (ENEA).

    Full Text Available Nel Parco Nazionale d'Abruzzo è stata studiata la selezione dell'habitat invernale di cervo e capriolo da aprile a maggio del 2000 e del 2002, in un'area caratterizzata da boschi di faggio, rimboschimenti a pino nero e pascoli. È stata utilizzata la tecnica del pellet group count, su transetti lineari larghi 2 metri, individuati ogni 100 m di quota, lungo le isoipse da 1350 a 1950 m s.l.m. Sono stati percorsi 61 km ed è stata campionata un'area di 12 ha. Per ogni gruppo di escrementi (1583 per il cervo e 946 per il capriolo sono state rilevate l'altitudine, la pendenza, l'esposizione e il tipo di vegetazione. È stato assunto che tutti gli habitat fossero ugualmente disponibili ed accessibili e che le disponibilita fossero conosciute (Alldredge et al., 1998. I dati raccolti sono stati elaborati applicando il test del Χ², la statistica di Bonferroni (Neu et al., 1974 e l'indice Jacobs (Jacobs, 1974. Il cervo ha selezionato aree comprese tra 1300 e 1500 m s.l.m.

Le due specie selezionano le stesse risorse, suggerendo, così come riscontrato da altri autori (Welch, 1989, una convergenza per quanto riguarda l'uso invernale dell'habitat. La scelta d'aree poste a quote medio-basse, di zone scoscese e di versanti meridionali potrebbe essere legata alla minore altezza e persistenza

The main goals of this initiative were to inform people of the ongoing seismic activity in Italy and around the World, to communicate the results of scientific research in seismology, and to increase the knowledge of seismic hazard of the people. To date, after almost two years from the start, we have published 52 original videos on YouTube, through the collaboration of many researchers at the Istituto Nazionale di Geofisica e Vulcanologia (INGV. The videos are organized into eight play lists: (i earthquakes in Italy; (ii earthquakes worldwide; (iii the 2009 L’Aquila, Italy, earthquake; (iv ongoing seismic activity; (v tsunami; (vi earthquake prediction; (vii seismic hazard; and (viii May 11 2011 (when a major earthquake was predicted to hit Rome. To date, the total number of views is over 466,000, with two peaks of more than 20,000/day after the Tohoku, Japan, earthquake (March 2011 and before the presumed prediction of a major earthquake to hit Rome on May 11, 2011. The most popular videos (6 have been viewed more than 20,000 times, with a maximum of over 67,000. We think that this initiative has increased people’s knowledge and awareness of seismic risk, although at the moment the outreach is limited only to a specific (but growing target of citizens. In the future, we will try to improve the technical aspects of our video communication, and we will try to broaden our audience. We have learned that when specific earthquakes occur (or even when there are unfounded predictions about upcoming seismic events this is when the attention is highest, which represent the best occasions to move forward towards improved risk communication strategies.

    Full Text Available This study provides the mathematical framework for the rigorous combination of coseismic offsets observed by a global positioning system (GPS network and investigates the results obtained on the occasion of the recent Emilia earthquakes (Italy. This seismic sequence that affected northern Italy from May 20, 2012, allowed two offset fields to be computed, one with reference to the mainshock (M 5.9, followed by two other M 5.1 events on the same day, and a second with reference to the replicas that occurred on May 29, 2012 (M 5.8, M 5.3 and M 5.2; ISIDe data archive, http://iside.rm.ingv.it. The final displacement field is basically the result of a comparison and validation process with repeated feedback between the different analysis groups at the Istituto Nazionale di Geofisica e Vulcanologia (INGV; National Institute of Geophysics and Volcanology that was established to obtain prompt coseismic displacement solutions, as precise as possible, and in the first days after an event. This is important for early seismic-source evaluation as it represents the most complete and validated dataset at the very early stage of a seismic crisis, and it is also extremely useful in reducing random and systematic errors in the estimated parameters. This study is the result of a cooperative effort that involved different research groups at INGV, with the sharing of all of the collected GPS data. The intention was to compare these results and thus reducing sources of error associated with individual processing strategies, to allow the final combination of the different displacement fields into a single consensus solution. The process assessed the robustness of each single GPS result, thus minimizing erroneous interpretations of individual solutions. […

    Surgery of brainstem lesions is increasingly performed despite the fact that surgical indications and techniques continue to be debated. The deep pons, in particular, continues to be a critical area in which the specific risks related to different surgical strategies continue to be examined. With the intention of bringing new knowledge into this important arena, the authors systematically examined the results of brainstem surgeries that have been performed through the lateral infratrigeminal transpontine window. Between 1990 and 2013, 29 consecutive patients underwent surgery through this window for either biopsy sampling or for removal of a deep pontine lesion. All of this work was performed at the Department of Neurosurgery of the Istituto Nazionale Neurologico "Carlo Besta", in Milan, Italy. A retrospective analysis of the findings was conducted with the intention of bringing further clarity to this important surgical strategy. The lateral infratrigeminal transpontine window was exposed through 4 different approaches: 1) classic retrosigmoid (15 cases), 2) minimally invasive keyhole retrosigmoid (10 cases), 3) translabyrinthine (1 case), and 4) combined petrosal (3 cases). No deaths occurred during the entire clinical study. The surgical complications that were observed included hydrocephalus (2 cases) and CSF leakage (1 case). In 6 (20.7%) of 29 patients the authors encountered new neurological deficits during the immediate postoperative period. All 6 of these patients had undergone lesion removal. In only 2 of these 6 patients were permanent sequelae observed at 3 months follow-up. These findings show that 93% of the patients studied did not report any permanent worsening of their neurological condition after this surgical intervention. This retrospective study supports the idea that the lateral infratrigeminal transpontine window is both a low-risk and safe corridor for either biopsy sampling or for removal of deep pontine lesions.

    To examine surgical findings and results of microvascular decompression (MVD) for trigeminal neuralgia (TN), including patients with multiple sclerosis, to bring new insight about the role of microvascular compression in the pathogenesis of the disorder and the role of MVD in its treatment. Between 1990 and 1998, 250 patients affected by trigeminal neuralgia underwent MVD in the Department of Neurosurgery of the "Istituto Nazionale Neurologico C Besta" in Milan. Limiting the review to the period 1991-6, to exclude the "learning period" (the first 50 cases) and patients with less than 1 year follow up, surgical findings and results were critically analysed in 148 consecutive cases, including 10 patients with multiple sclerosis. Vascular compression of the trigeminal nerve was found in all cases. The recurrence rate was 15.3% (follow up 1-7 years, mean 38 months). In five of 10 patients with multiple sclerosis an excellent result was achieved (follow up 12-39 months, mean 24 months). Patients with TN for more than 84 months did significantly worse than those with a shorter history (p<0.05). There was no mortality and most complications occurred in the learning period. Surgical complications were not related to age of the patients. Aetiopathogenesis of trigeminal neuralgia remains a mystery. These findings suggest a common neuromodulatory role of microvascular compression in both patients with or without multiple sclerosis rather than a direct causal role. MVD was found to be a safe and effective procedure to relieve typical TN in patients of all ages. It should be proposed as first choice surgery to all patients affected by TN, even in selected cases with multiple sclerosis, to give them the opportunity of pain relief without sensory deficits.

    From the stripping points, the high intensity proton beam of a compact cyclotron travels through the fringe field area of the machine to the combination magnet. Starting from there the beams with various energy is transferred to the switching magnet for distribution to the beam line targets. In the design of the extraction and transport system for the compact proton cyclotron facilities, such as the 70 MeV in France and the 100 MeV in China, the space charge effect as the beam crosses the fringe field has not been previously considered; neither has the impact on transverse beam envelope coupled from the longitudinal direction. Those have been concerned much more with the higher beam-power because of the beam loss problem. In this paper, based on the mapping data of 70 MeV cyclotron including the fringe field by BEST Cyclotron Inc (BEST) and combination magnet field by China Institute of Atomic Energy (CIAE), the beam extraction and transport are investigated for the 70 MeV cyclotron used on the SPES project at Istituto Nazionale di Fisica Nucleare, Laboratori Nazionali di Legnaro (INFN-LNL). The study includes the space charge effect and longitudinal and transverse coupling mentioned above, as well as the matching of beam optics using the beam line for medical isotope production as an example. In addition, the designs of the ±45° switching magnets and the 60° bending magnet for the extracted beam with the energy from 35 MeV to 70 MeV have been made. Parts of the construction and field measurements of those magnets have been done as well. The current result shows that, the design considers the complexity of the compact cyclotron extraction area and fits the requirements of the extraction and transport for high intensity proton beam, especially at mA intensity levels.

    Using data samples collected at center-of-mass energies of √s = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a search for the process e+e- → γχcJ (J=0, 1, 2) and find evidence for e+e- → γχc1 and e+e- → γχc2 with statistical significances of 3.0σ and 3.4σ, respectively. The Born cross sections σB(e+e- → γχcJ), as well as their upper limits at the 90% confidence level (C.L.) are determined at each center-of-mass energy.

    In a variability survey of M81 using the Large Binocular Telescope we have discovered a peculiar eclipsing binary (MV ~ - 7.1) in the field of the dwarf galaxy Holmberg IX. It has a period of 271 days, and the light curve is well fit by an overcontact model in which both stars are overflowing their Roche lobes. It is composed of two yellow supergiants (V - Isimeq 1 mag, Teffsimeq 4800 K), rather than the far more common red or blue supergiants. Such systems must be rare. While we failed to find any similar systems in the literature, we did, however, note a second example. The SMC F0 supergiant R47 is a bright (MV ~ - 7.5) periodic variable whose All Sky Automated Survey (ASAS) light curve is well fit as a contact binary with a 181 day period. We propose that these systems are the progenitors of supernovae like SN 2004et and SN 2006ov, which appeared to have yellow progenitors. The binary interactions (mass transfer, mass loss) limit the size of the supergiant to give it a higher surface temperature than an isolated star at the same core evolutionary stage. We also discuss the possibility of this variable being a long-period Cepheid. Based on data acquired using the Large Binocular Telescope (LBT).

  13. Bushido as allied: The Japanese warrior in the cultural production of Fascist Italy (1940-1943

    Full Text Available Introduction: After the signing of the alliance among Japan, Germany and Italy’s governments in September 1940, several journals arose in order to spread the Japanese culture among people who knew very little about Italy’s new allied. Some documentaries also had the same function. Methods: The numerous textual and iconographical references concerning the Japanese warriors’ anthropology published in some Italian magazines during the 1940s have been compared, as well as to the few Italian monographs on the same theme and to some documentaries by Istituto Nazionale Luce, government propaganda organ. This subject has also been compared to the first Italian cultural production, concerning Japan, which dated back to the first decades of the 20th century. Moreover different intellectuals’ biographies of those times have been deeply analyzed. Results: Comparing to each other the anthropological references about Japan in the Italian cultural production during the Second World War, we can notice a significant ideological homogeneity. This can be explained through their writers’ common sharing of the militaristic, hierarchical and totalitarian doctrine of the Fascist Regime. The Fascist ideology can be summarized in the Bushido concept, as Inazo Nitobe defined it in 1916. This concept was already known in Italy on the early 20th century, far before Fascism. Discussions and conclusions: We can see how Italian perception of the Japanese anthropology on the early 20th century didn’t change over time and how its features will re-appear in the 40s under the influence of the Italian-Japanese coalition. So, Bushido became the essence of the Japanese military and national identity that Fascist Italy took as example for mass education. Some of these stereotypes will re-appear after the war and until recent times in popular culture and in mass perception of Japanese martial arts.

    Diabetes mellitus, a metabolic disease characterized by high blood glucose levels (hyperglycemia) due to defects in insulin secretion, or action, or both, is a debilitating disease leading to other complications and death of many people in the world. Some of the medicinal plants implicated in the herbal recipes for the treatment of diabetes in Nigeria have been reported. Additional medicinal plants used for the treatment of diabetes in Nigeria are presented in this work. These medicinal plants are becoming increasingly important and relevant as herbal drugs due to their use as antioxidants, nutraceuticals, food additives and supplements in combating diabetes. Elemental compositions of these anti-diabetic medicinal plants were determined using PIXE technique. The 1.8 MV collimated proton beam from the 2.5 MV AN 2000 Van de Graaff accelerator at Istituto Nazionale di Fisica Nucleare (INFN), Laboratori Nazionali di Legnaro (LNL) Legnaro (Padova) Italy was employed for the work. The results show the detection of twenty-one elements which include Mg, P, Ca, K, Mn, Cu, Zn, S, Cr, Co, Ni and V that are implicated in the regulation of insulin and the control of the blood-sugar levels in the human body. The entire plant of Boerhavia diffusa, Securidaca longipedunculata stem, leaves of Peperomia pellucida, Macrosphyra longistyla, Olax subscorpioidea, Phyllanthus muerillanus, Jatropha gossypifolia, Cassia occidentalis, Phyllanthus amarus, and leaf and stem of Murraya koenigii, which have high concentrations of these elements could be recommended as vegetables, nutraceuticals, food additives, supplements and drugs in the control and management of diabetes, if toxicity profiles indicate that they are safe. However, significantly high contents of Al and Si in the entire plant of Bryophyllum pinnatum, and As, Cr, and Cu in Ocimum gratissimum leaf suggest that these plants should be avoided by diabetic patients to prevent complications.

    A PTW Optidos plastic scintillation and a PTW natural diamond detectors were calibrated in terms of absorbed dose to water with β fields produced by 90 Sr + 90 Y and 85 Kr reference sources. Each source was characterized at the Italian National Metrological Institute - the Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti of ENEA (ENEA-INMRI) - for two different series, 1 and 2, of ISO reference β-particle radiation fields. Beam flattening filters were used for the series 1 β fields to give uniform absorbed dose rates over a large area at a source-to-reference plane distance of 30 cm. The series 2 β fields were produced at source-to-reference plane distance of 10 cm, without the beam flattening filters, in order to obtain higher absorbed dose rates. The reference absorbed dose rate values were directly determined by the Italian national standard for β-particle dosimetry (a PTW extrapolation ionization chamber) for the series 1 β fields and by a calibrated transfer standard chamber, (a Capintec thin fixed-volume parallel plate ionization chamber) for the series 2 β fields. Finally the two solid state detectors were calibrated in terms of absorbed dose to water with the series 2 β field. The expanded uncertainties of the calibration coefficients obtained for the plastic scintillation dosimeter were 10% and 12% (2SD) for the 90 Sr + 90 Y and the 85 Kr sources, respectively. The expanded uncertainties obtained for the diamond dosimeter were 10% (2SD) and 16% (2SD) for the 90 Sr + 90 Y and the 85 Kr sources, respectively. The good results obtained with the 90 Sr + 90 Y and the 85 Kr β sources encourage to implement this procedure to calibrate this type of detectors at shorter distances and with other β sources of interest in brachytherapy, for example the 106 Ru source

    As gas giant planets and brown dwarfs radiate away the residual heat from their formation, they cool through a spectral type transition from L to T, which encompasses the dissipation of cloud opacity and the appearance of strong methane absorption. While there are hundreds of known T-type brown dwarfs, the first generation of directly imaged exoplanets were all L type. Recently, Kuzuhara et al. announced the discovery of GJ 504 b, the first T dwarf exoplanet. GJ 504 b provides a unique opportunity to study the atmosphere of a new type of exoplanet with a ˜500 K temperature that bridges the gap between the first directly imaged planets (˜1000 K) and our own solar system's Jupiter (˜130 K). We observed GJ 504 b in three narrow L-band filters (3.71, 3.88, and 4.00 μm), spanning the red end of the broad methane fundamental absorption feature (3.3 μm) as part of the LBTI Exozodi Exoplanet Common Hunt (LEECH) exoplanet imaging survey. By comparing our new photometry and literature photometry with a grid of custom model atmospheres, we were able to fit GJ 504 b's unusual spectral energy distribution for the first time. We find that GJ 504 b is well fit by models with the following parameters: Teff = 544 ± 10 K, g Germany.

    Seismic quiescence before major worldwide earthquakes has been reported by many authors. We have analyzed the seismicity preceding the last damaging 2016-2017 seismic sequence occurred in central Italy, and we have characterized the temporal and spatial extension of the foregoing seismic quiescence. The multiple mainshock sequence (24/08/2016, Mw 6.0; 26/10/2016 Mw 5.4 and 5.9; 30/10/2016, Mw 6.5), which occurred in central Italy, caused the death of nearly 300 people and widespread destruction of entire villages. The Mw 6.5 earthquake was the most powerful recorded in Italy since the 1980 M 6.9 Irpinia earthquake. The Region-Time-Length (RTL) method has been used to quantitatively analyze the seismic quiescence preceding the first Mw 6.0 Amatrice mainshock. This analysis was performed using the earthquake catalogue maintained by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) declustered using a novel statistical approach, which is based on the "nearest-neighbor" distances between pairs of earthquakes in the space-time-energy domain. A well-evident quiescence that preceded the sequence was detected. The quiescence extended throughout a broad region north of the epicenter. The largest event of the sequence and its aftershocks covered most of the quiescence region, except for a small area to the west. The quiescence started from the beginning of September 2015 and lasted for approximately 1 year, up to the Amatrice mainshock. The results obtained have been compared with those of previous seismic sequences occurred in Italy. A similar analysis applied to the 1997-1998, Mw 5.7 Umbria-Marche earthquakes located at the northern termination of the Amatrice sequence, showed a decrease in RTL corresponding to a seismic quiescence, followed by a foreshock activation in the epicentral area before the occurrence of the mainshock.

    We present the analysis of rotational and translational ground motions from earthquakes recorded during October/November, 2016, in association with the Central Italy seismic-sequence. We use co-located measurements of the vertical ground rotation rate from a large ring laser gyroscope (RLG), and the three components of ground velocity from a broadband seismometer. Both instruments are positioned in a deep underground environment, within the Gran Sasso National Laboratories (LNGS) of the Istituto Nazionale di Fisica Nucleare (INFN). We collected dozens of events spanning the 3.5-5.9 Magnitude range, and epicentral distances between 30 km and 70 km. This data set constitutes an unprecedented observation of the vertical rotational motions associated with an intense seismic sequence at local distance. Under the plane wave approximation we process the data set in order to get an experimental estimation of the events back azimuth. Peak values of rotation rate (PRR) and horizontal acceleration (PGA) are markedly correlated, according to a scaling constant which is consistent with previous measurements from different earthquake sequences. We used a prediction model in use for Italy to calculate the expected PGA at the recording site, obtaining consequently predictions for PRR. Within the modeling uncertainties, predicted rotations are consistent with the observed ones, suggesting the possibility of establishing specific attenuation models for ground rotations, like the scaling of peak velocity and peak acceleration in empirical ground-motion prediction relationships. In a second step, after identifying the direction of the incoming wave-field, we extract phase velocity data using the spectral ratio of the translational and rotational components.. This analysis is performed over time windows associated with the P-coda, S-coda and Lg phase. Results are consistent with independent estimates of shear-wave velocities in the shallow crust of the Central Apennines.

  1. Groundwater geochemistry of the Mt. Vesuvius area: implications for volcano surveillance and relationship with hydrological and seismic signals

    Full Text Available Geochemical data obtained between 1998 and 2011 at the Mt. Vesuvius aquifer are discussed, focusing on the effects of both the hydrological regime and the temporal pattern of local seismicity. Water samples were collected in a permanent network of wells and springs located in the areas that are mostly affected by the ascent of magmatic volatiles, and their chemical composition and dissolved gas content were analyzed. As well as the geochemical parameters that describe the behavior of groundwater at Mt. Vesuvius, we discuss the temporal distribution of volcano-tectonic earthquakes. The seismological data set was collected by the stations forming the permanent and mobile network of the Istituto Nazionale di Geofisica e Vulcanologia - Osservatorio Vesuviano (INGV-OV. Our analysis of seismic data collected during 1998-2011 identified statistically significant variations in the seismicity rate, marked by phases of decreasing activity from October 1999 to May 2001 and increasing activity from August 2004 to mid-2006. The water chemistry shows peculiar patterns, characterized by a changeable input of CO2-rich and saline water, which must be related to either a changing stress field or an increased input of CO2-rich vapor. The water chemistry data from 1999 to 2003 account for both higher fluid pressure (which induced the seismic crisis of 1999 that peaked with a 3.6-magnitude earthquake in October 1999 and the increased input of CO2-rich fluids. The highest emission of CO2 from the crater fumaroles and the corresponding increase in dissolved carbon in groundwater characterize the phase of low seismicity. The termination of the phase of intense deep degassing is associated with a change in water chemistry and a peculiar seismic event that was recorded in July 2003. All these seismic and geochemical patterns are interpreted according to temporal variations in the regional and local stress field.

  2. Measures of maximum magnetic field in 3 GHz radio frequency superconducting cavities; Mesures du gradient accelerateur maximum dans des cavites supraconductrices en regime impulsionnel a 3 GHz

    Theoretical models have shown that the maximum magnetic field in radio frequency superconducting cavities is the superheating field H{sub sh}. For niobium, H{sub sh} is 25 - 30% higher than the thermodynamical H{sub c} field: H{sub sh} within (240 - 274) mT. However, the maximum magnetic field observed so far is in the range H{sub c,max} = 152 mT for the best 1.3 GHz Nb cavities. This field is lower than the critical field H{sub c1} above which the superconductor breaks up into divided normal and superconducting zones (H{sub c1}{<=}H{sub c}). Thermal instabilities are responsible for this low value. In order to reach H{sub sh} before thermal breakdown, high power short pulses are used. The cavity needs then to be strongly over-coupled. The dedicated test bed has been built from the collaboration between Istituto Nazionale di Fisica Nucleare (INFN) - Sezione di Genoa, and the Service d'Etudes et Realisation d'Accelerateurs (SERA) of Laboratoire de l'Accelerateur Lineaire (LAL). The maximum magnetic field, H{sub rf,max}, measurements on INFN cavities give lower results than the theoretical speculations and are in agreement with previous results. The superheating magnetic fields is linked to the magnetic penetration depth. This superconducting characteristic length can be used to determine the quality of niobium through the ratio between the resistivity measured at 300 K and 4.2 K in the normal conducting state (RRR). Results have been compared to previous ones and agree pretty well. They show that the RRR measured on cavities is superficial and lower than the RRR measured on samples which concerns the volume.

    From the stripping points, the high intensity proton beam of a compact cyclotron travels through the fringe field area of the machine to the combination magnet. Starting from there the beams with various energy is transferred to the switching magnet for distribution to the beam line targets. In the design of the extraction and transport system for the compact proton cyclotron facilities, such as the 70 MeV in France and the 100 MeV in China, the space charge effect as the beam crosses the fringe field has not been previously considered; neither has the impact on transverse beam envelope coupled from the longitudinal direction. Those have been concerned much more with the higher beam-power because of the beam loss problem. In this paper, based on the mapping data of 70 MeV cyclotron including the fringe field by BEST Cyclotron Inc (BEST) and combination magnet field by China Institute of Atomic Energy (CIAE), the beam extraction and transport are investigated for the 70 MeV cyclotron used on the SPES project at Istituto Nazionale di Fisica Nucleare, Laboratori Nazionali di Legnaro (INFN–LNL). The study includes the space charge effect and longitudinal and transverse coupling mentioned above, as well as the matching of beam optics using the beam line for medical isotope production as an example. In addition, the designs of the ±45° switching magnets and the 60° bending magnet for the extracted beam with the energy from 35 MeV to 70 MeV have been made. Parts of the construction and field measurements of those magnets have been done as well. The current result shows that, the design considers the complexity of the compact cyclotron extraction area and fits the requirements of the extraction and transport for high intensity proton beam, especially at mA intensity levels.

  4. Interferometric evidence for the observation of ground backscatter originating behind the CUTLASS coherent HF radars

    Interferometric techniques allow the SuperDARN coherent HF radars to determine the elevation angles of returned backscatter, giving information on the altitude of the scatter volume, in the case of ionospheric backscatter, or the reflection altitude, in the case of ground backscatter. Assumptions have to be made in the determination of elevation angles, including the direction of arrival, or azimuth, of the returned signals, usually taken to be the forward look-direction (north) of the radars, specified by the phasing of the antenna arrays. It is shown that this assumption is not always valid in the case of ground backscatter, and that significant returns can be detected from the backward look-direction of the radars. The response of the interferometer to backscatter from behind the radar is modelled and compared with observations. It is found that ground backscatter from a field-of-view that is the mirror image of the forward-looking field-of-view is a common feature of the observations, and this interpretation successfully explains several anomalies in the received backscatter.

    To investigate the nature of the {{\\psi }}(3770) resonance and to measure the cross section for {{{e}}}+{{{e}}}-\\to {{D}}\\bar{{{D}}}, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII collider in the year 2010. By analyzing the large angle Bhabha scattering events, we measure the integrated luminosity of the data sample at each center-of-mass energy point. The total integrated luminosity of the data sample is 76.16+/- 0.04+/- 0.61 {pb}}-1, where the first uncertainty is statistical and the second systematic.

    The star HD 144548 (=HIP 78977; TYP 6212-1273-1) has been known as a detached eclipsing binary and a bona-fide member of the Upper Scorpius OB association. Continuous photometry from the K2 mission on Campaign Two has revealed the presence of additional eclipses due to the presence of a third star in the system. These are explained by a system composed of the two previously known members of the eclipsing system (Ba and Bb) with a period of 1.63 d, orbiting around an F7-F8V star with a period of 33.945 ± 0.002 d in an eccentric orbit (eA = 0.2652 ± 0.0003). The timing of the eclipses of Ba and Bb reveals the same 33.9 d periodicity, which we interpret as the combination of a light time effect combined with dynamical perturbations on the close system. Here we combine radial velocities and analytical approximations for the timing of the eclipses to derive masses and radii for the three components of the system. We obtain a mass of 1.44 ± 0.04 M⊙ and radius of 2.41 ± 0.03 R⊙ for the A component, and almost identical masses and radii of about 0.96 M⊙ and 1.33 R⊙ for each of the two components of the close binary. HD 144548 is the first triply eclipsing system for which radial velocities of all components could be measured. Partially based on observations made with the Italian Telescopio Nazionale Galileo (TNG) operated by the Fundación Galileo Galilei of the INAF, the Nordic Optical Telescope, operated by the Nordic Optical Telescope Scientific Association, and the William Herschel Telescope (programme DDT58 - PI Lodieu) operated by the Isaac Newton Group on the island of La Palma at the Spanish Observatorio Roque de los Muchachos of the IAC.

    We report the discovery of a super-Earth orbiting at the inner edge of the habitable zone of the star GJ 625 based on the analysis of the radial-velocity (RV) time series from the HARPS-N spectrograph, consisting of 151 HARPS-N measurements taken over 3.5 yr. GJ 625 b is a planet with a minimum mass Msini of 2.82 ± 0.51 M⊕ with an orbital period of 14.628 ± 0.013 days at a distance of 0.078 AU from its parent star. The host star is the quiet M2 V star GJ 625, located at 6.5 pc from the Sun. We find the presence of a second radial-velocity signal in the range 74-85 days that we relate to stellar rotation after analysing the time series of Ca II H&K and Hα spectroscopic indicators, the variations of the FWHM of the CCF, and the APT2 photometric light curves. We find no evidence linking the short-period radial-velocity signal to any activity proxy. Based on observations made with the Italian Telescopio Nazionale Galileo (TNG), operated on the island of La Palma by the INAF - Fundación Galileo Galilei at the Roche de Los Muchachos Observatory of the Instituto de Astrofísica de Canarias (IAC); photometric observations made with the robotic telescope APT2 (within the EXORAP programme) located at Serra La Nave on Mt. Etna; and lucky imaging observations made with the Telescopio Carlos Sánchez operated on the island of Tenerife by the Instituto de Astrofísica de Canarias in the Spanish Observatorio del Teide.Tables A.1-A.5 are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (http://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/605/A92

    Context. Short- to mid-term magnetic phenomena on the stellar surface of M-type stars can resemble the effects of planets in radial velocity data, and may also hide them. Aims: We analyze 145 spectroscopic HARPS-N observations of GJ 3942 taken over the past five years and additional photometry in order to disentangle stellar activity effects from genuine Doppler signals as a result of the orbital motion of the star around the common barycenter with its planet. Methods: To achieve this, we use the common methods of pre-whitening, and treat the correlated red noise by a first-order moving average term and by Gaussian-process regression following an MCMC analysis. Results: We identify the rotational period of the star at 16.3 days and discover a new super-Earth, GJ 3942 b, with an orbital period of 6.9 days and a minimum mass of 7.1 M⊕. An additional signal in the periodogram of the residuals is present, but at this point we cannot claim with sufficient significance that it is related to a second planet. If confirmed, this planet candidate would have a minimum mass of 6.3 M⊕ and a period of 10.4 days, which might indicate a 3:2 mean-motion resonance with the inner planet. Based on observations made with the Italian Telescopio Nazionale Galileo (TNG), operated on the island of La Palma by the INAF - Fundación Galileo Galilei at the Roque de los Muchachos Observatory of the Instituto de Astrofísica de Canarias (IAC); photometric observations from the APACHE array located at the Astronomical Observatory of the Aosta Valley; photometric observations made with the robotic APT2 (within the EXORAP program) located at Serra La Nave on Mt.

    Young Researcher Meeting, Torino 2016 F Agostini, C Antolini, A Avella, G Cattani, R Cuccaro, A Cultrera, M Di Stefano, G Fragione, L Lolli, M Migliaccio, L Pagnanini, E Pessana, F Piacentini, D Pietrobon, E Pusceddu, R Romeo, M Serra, E Simonetto, F Stellato Preface The Young Researcher Meeting (www.yrmr.it) has been established as a forum for students, postdoctoral fellows and young researchers determined to play a proactive role in the scientific progress. Since 2009 we run itinerant yearly meetings to discuss the most recent developments and achievements in Physics, as we are firmly convinced that sharing expertise and experience is the foundation of the research activity. One of the main purposes of the conference is actually to create an international network of young researchers, both experimentalists and theoreticians, and fruitful collaborations across the different branches of Physics. The format we chose is an informal meeting primarily aimed at students and researchers at the beginning of their scientific career, who are encouraged to present their work in brief presentations able to provide genuine engagement of the audience and cross-pollination of ideas. The 7 th edition of the Young Researcher Meeting was held at the Istituto Nazionale di Ricerca Metrologica (INRiM) in Turin, the Italian National Metrology Institute responsible for the national standards of the International System of Units. The conference took place from Monday 24 th to Wednesday 26 th October 2016. This edition gathered 120 participants belonging to universities and research centres from all over the world. The plenary talk sessions covered several areas of pure and applied Physics, and they were complemented by an extremely rich and interactive poster session, which was also extended to the coffee breaks. The programme included a “poster and wine” session on the first evening, a guided tour at the Turin Astrophysical Observatory and a very enjoyable and friendly conference

    We present an analysis of a slightly eccentric (e = 0.05), partially eclipsing, long-period (P = 69.73 days) main-sequence binary system (WOCS 12009, Sanders 1247) in the benchmark old open cluster M67. Using Kepler K2 and ground-based photometry, along with a large set of new and reanalyzed spectra, we derived highly precise masses (1.111 ± 0.015 and 0.748 ± 0.005 M ⊙) and radii (1.071 ± 0.008 ± 0.003 and 0.713 ± 0.019 ± 0.026 R ⊙, with statistical and systematic error estimates) for the stars. The radius of the secondary star is in agreement with theory. The primary, however, is approximately 15% smaller than reasonable isochrones for the cluster predict. Our best explanation is that the primary star was produced from the merger of two stars, as this can also account for the nondetection of photospheric lithium and its higher temperature relative to other cluster main-sequence stars at the same V magnitude. To understand the dynamical characteristics (low measured rotational line broadening of the primary star and low eccentricity of the current binary orbit), we believe that the most probable (but not the only) explanation is the tidal evolution of a close binary within a primordial triple system (possibly after a period of Kozai–Lidov oscillations), leading to merger approximately 1 Gyr ago. This star appears to be a future blue straggler that is being revealed as the cluster ages and the most massive main-sequence stars die out.

    We aim to investigate the presence of signatures of magnetic cycles and rotation on a sample of 71 early M-dwarfs from the HADES RV programme using high-resolution time-series spectroscopy of the Ca II H&K and Hα chromospheric activity indicators, the radial velocity series, the parameters of the cross correlation function and the V -band photometry. We used mainly HARPS-N spectra, acquired over 4 yr, and add HARPS spectra from the public ESO database and ASAS photometry light-curves as support data, extending the baseline of the observations of some stars up to 12 yr. We provide log10(R'HK) measurements for all the stars in the sample, cycle length measurements for 13 stars, rotation periods for 33 stars and we are able to measure the semi-amplitude of the radial velocity signal induced by rotation in 16 stars. We complement our work with previous results and confirm and refine the previously reported relationships between the mean level of chromospheric emission, measured by the log10(R'HK), with the rotation period, and with the measured semi-amplitude of the activity induced radial velocity signal for early M-dwarfs. We searched for a possible relation between the measured rotation periods and the lengths of the magnetic cycle, finding a weak correlation between both quantities. Using previous v sin i measurements we estimated the inclinations of the star's poles to the line of sight for all the stars in the sample, and estimate the range of masses of the planets GJ 3998 b and c (2.5-4.9 and 6.3-12.5 M⊕), GJ 625 b (2.82 M⊕), GJ 3942 b (7.1-10.0 M⊕) and GJ 15A b (3.1-3.3 M⊕), assuming their orbits are coplanar with the stellar rotation. Based on: observations made with the Italian Telescopio Nazionale Galileo (TNG), operated on the island of La Palma by the INAF - Fundación Galileo Galilei at the Roche de Los Muchachos Observatory of the Instituto de Astrofísica de Canarias (IAC); observations made with the HARPS instrument on the ESO 3.6-m telescope

  6. Memories of the past contribute to prevention: photography as a direct means for public understanding of science

    Full Text Available There are thousands of ways to achieve a sustainable future for our Planet. Some of these follow high-value scientific research activities, while others simply aim to increase people’s awareness of what can and should be done to improve our, and our children’s, quality of life. The easiest way to develop this specific kind of ‘spread of culture’ consists of bringing back to life what was preserved of the history of a population and of a territory, by representing it in a renewed form, and by making it ‘food for thought’. The Istituto Nazionale di Geofisica e Vulcanologia (INGV followed this approach and decided to publish two volumes where the objective was to make people more aware of the geological and volcanic risks in some specific areas of Italy. The immediacy of the photography is used to tell the stories of volcanoes and earthquakes, to represent past events that have become ‘memories’. and to use these as a basis to build a better future. Terremoto Calabro Messinese, 1908/2008 and Terre di Fuoco are the two photographic books that have been published by INGV in cooperation with Alinari, the oldest firm in the world in the field of photography and image communication. The photographs selected to be included in the two books had a double significance: on the one side, they had to convey to the reader the immediacy of the emotions that other people had felt and lived; and on the other side, they had to make people understand the importance of prevention. The fascination of history, the importance of memories of the past, and the extraordinary strength of images help the reader build a link between the past, the present and the future, where the lessons learnt from past centuries and from the study of the Earth and its energy help us to understand which steps should be taken to achieve a ‘sustainable’ future.

  7. A spectral study of the mid-latitude sporadic E layer characteristic oscillations comparable to those of the tidal and the planetary waves

    In this paper different spectral analyses are employed to investigate the tidal and planetary wave periodicities imprinted in the following two main characteristics of the sporadic E (Es) layer: the top frequency (ftEs) and the lowest virtual height (h‧Es). The study is based on ionograms recorded during the summertime of 2013, and precisely in June, July, August and September, by the Advanced Ionospheric Sounder by Istituto Nazionale di Geofisica e Vulcanologia (AIS-INGV) ionosondes installed at Rome (41.8°N, 12.5°E) and Gibilmanna (37.9°N, 14.0°E), Italy. It was confirmed that the diurnal and semidiurnal atmospheric tides play a fundamental role in the formation of the mid-latitude Es layers, acting through their vertical wind-shear forcing of the long-living metallic ions in the lower thermosphere, and at the same time it was found that the planetary atmospheric waves might affect the Es layers acting through their horizontal wind-shear forcing with periods close to the normal Rossby modes, that is 2, 5, 10 and 16 days. The wavelet analysis shows also that the ftEs and h‧Es tidal oscillations undergo a strong amplitude modulation with periods of several days and with important differences between the two parameters. This amplitude modulation, characterizing markedly the first thirty days of the ftEs spectrogram, suggests that Es layers are affected indirectly by planetary waves through their nonlinear interaction with the atmospheric tides at lower altitudes. This study wants to be a continuation of the Haldoupis et al. (2004) work in order to verify their results for the foEs characteristic and on the other hand to extend the study also to the h‧Es characteristic not yet shown so far. Anyhow, the study confirms that ionosonde data, especially those registered in summertime, represent a powerful tool for studying tidal and planetary waves properties and their climatology in the mesosphere-low-thermosphere region.

    Full Text Available In 1995, we published the first release of the Catalogo dei Forti Terremoti in Italia, 461 a.C. - 1980, in Italian (Boschi et al., 1995. Two years later this was followed by a second release, again in Italian, that included more earthquakes, more accurate research and a longer time span (461 B.C. to 1990 (Boschi et al., 1997. Aware that the record of Italian historical seismicity is probably the most extensive of the whole world, and hence that our catalogue could be of interest for a wider interna-tional readership, Italian was clearly not the appropriate language to share this experience with colleagues from foreign countries. Three years after publication of the second release therefore, and after much additional research and fine tuning of methodologies and algorithms, I am proud to introduce this third release in English. All the tools and accessories have been translated along with the texts describing the development of the underlying research strategies and current contents. The English title is Catalogue of Strong Italian Earthquakes, 461 B.C. to 1997. This Preface briefly describes the scientific context within which the Catalogue of Strong Italian Earthquakes was conceived and progressively developed. The catalogue is perhaps the most impor-tant outcome of a well-established joint project between the Istituto Nazionale di Geofisica, the leading Italian institute for basic and applied research in seismology and solid earth geophysics, and SGA (Storia Geofisica Ambiente, a private firm specialising in the historical investigation and systematisation of natural phenomena. In her contribution "Method of investigation, typology and taxonomy of the basic data: navigating between seismic effects and historical contexts", Emanuela Guidoboni outlines the general framework of modern historical seismology, its complex relation with instrumental seismology on the one hand and historical research on the other. This presentation also highlights

  9. 11th International Conference on Clustering Aspects of Nuclear Structure and Dynamics

    International Nuclear Information System (INIS)

    2017-01-01

    Preface The 11 th edition of the International Conference on Clustering Aspects of Nuclear Structure and Dynamics (CLUSTER‘16) was held in Napoli, Italy, on May 23-27 2016. All the Conference Sessions took place in the magnificent Complesso Monumentale dei Ss. Marcellino e Festo , located in the Historical Centre of Naples. This is one of the most prestigious building complexes of the Federico II University of Naples, the main home institution of the organizers, together with the Istituto Nazionale di Fisica Nucleare (Naples division). This building is 500 years old; in the XVIII century, it was reshaped by Luigi Vanvitelli, a famous architect of the pre-Neoclassical period in Italy, designer of the prestigious Royal Palace in the near town of Caserta. The site of Plenary Sessions was the Church of Ss. Marcellino e Festo , where all the participants were surrounded by the Baroque frescoes by Belisario Corenzio and, among the others, the paintings of Battistello Caracciolo, Massimo Stanzione, Giuseppe Simonelli and Francesco De Mura, important artists of the late Baroque period in South Italy. The sites of Parallel Sessions were two halls in the arcade of the S. Marcellino cloister: this gave the opportunity to the participants to enjoy the beauty of the architecture of the cloister with its fountains, gardens, sculptures. As organizers of the Conference, our main aims were: (1) to provide an excellent programme, with the expectation to be a reference point for the Nuclear Cluster Physics in the next four years; (2) to assure a very relaxing stay to the participants, allowing them to explore the bounty of artistic, and also culinary, masterpieces that Naples offers to its guests. The first point was assured by all the conveners that, with their excellent talks, gave a very precise and complete overview of the most recent achievements on Nuclear Cluster Physics, both from the experimental and theoretical point of view.

    A measurement of the number of J/ψ events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/ψ. The number of J/ψ events taken in 2009 is recalculated to be (223.7 ± 1.4) × 106, which is in good agreement with the previous measurement, but with significantly improved precision due to improvements in the BESIII software. The number of J/ψ events taken in 2012 is determined to be (1086.9 ± 6.0) × 106. In total, the number of J/ψ events collected with the BESIII detector is measured to be (1310.6 ± 7.0) × 106, where the uncertainty is dominated by systematic effects and the statistical uncertainty is negligible.

    We present analyses of rotational and translational ground motions from earthquakes recorded during October-November, 2016, in association with the Central Italy seismic-sequence. We use co-located measurements of the vertical ground rotation rate from a large ring laser gyroscope (RLG), and the three components of ground velocity from a broadband seismometer. Both instruments are positioned in a deep underground environment, within the Gran Sasso National Laboratories (LNGS) of the Istituto Nazionale di Fisica Nucleare (INFN). We collected dozen of events spanning the 3.5-5.9 Magnitude range, and epicentral distances between 40 km and 80 km. This data set constitutes an unprecedented observation of the vertical rotational motions associated with an intense seismic sequence at local distance. In theory - assuming plane wave propagation - the ratio between the vertical rotation rate and the transverse acceleration permits, in a single station approach, the estimation of apparent phase velocity in the case of SH arrivals or real phase velocity in the case of Love surface waves. This is a standard approach for the analysis of earthquakes at teleseismic distances, and the results reported by the literature are compatible with the expected phase velocities from the PREM model. Here we extend the application of the same approach to local events, thus exploring higher frequency ranges and larger rotation rate amplitudes. We use a novel approach to joint rotation/acceleration analysis based on the continuous wavelet transform (CWT). Wavelet coherence (WTC) is used as a filter for identifying those regions of the time-period plane where the rotation rate and transverse acceleration signals exhibit significant coherence. This allows retrieving estimates of phase velocities over the period range spanned by correlated arrivals. Coherency among ground rotation and translation is also observed throughout the coda of the P-wave arrival, an observation which is interpreted in

    Materials and components employed in the presence of intense neutron and gamma fields are expected to absorb high dose levels that may induce deep modifications of their physical and mechanical properties, possibly causing loss of their function. A protocol for irradiating elastomeric materials in reactor mixed neutron and gamma fields and for testing the evolution of their main mechanical and physical properties with absorbed dose has been developed. Four elastomeric compounds used for vacuum O-rings, one fluoroelastomer polymer (FPM) based and three ethylene propylene diene monomer rubber (EPDM) based, presently available on the market have been selected for the test. One EPDM is rated as radiation resistant in gamma fields, while the other elastomers are general purpose products. Particular care has been devoted to dosimetry calculations, since absorbed dose in neutron fields, unlike pure gamma fields, is strongly dependent on the material composition and, in particular, on the hydrogen content. The products have been tested up to about 2 MGy absorbed dose. The FPM based elastomer, in spite of its lower dose absorption in fast neutron fields, features the largest variations of properties, with a dramatic increase in stiffness and brittleness. Out of the three EPDM based compounds, one shows large and rapid changes in the main mechanical properties, whereas the other two feature more stable behaviors. The performance of the EPDM rated as radiation resistant in pure gamma fields does not appear significantly better than that of the standard product. The predictive capability of the accelerated irradiation tests performed as well as the applicable concepts of threshold of radiation damage is discussed in view of the use of the examined products in the selective production of exotic species facility, now under construction at the Legnaro National Laboratories of the Italian Istituto Nazionale di Fisica Nucleare. It results that a careful account of dose rate effects

    Data assimilation has raised new interest in the last years in the context of the environmental sciences. The swift increment of the attention paid to it in oceanography is due to the coming age of operational services for the marine environment which is going to dramatically increase the demand for accurate, timely and reliable estimates of the space and time distribution both for physical and in a near future for biogeochemical fields. Data assimilation combines information derived from measurements with knowledge of the rules that govern the evolution of the system of interest through formalization and implementation in numerical models. The importance of ocean data assimilation has been recognized by several international programmes as JGOFS, GOOS and CLIVAR. This work presents an eco-hydrodynamic model of the Mediterranean Sea developed at the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale - OGS, Trieste, Italy. It includes 3-D MOM-based hydrodynamics of the Mediterranean Sea, coupled with biochemical model of Nitrogen, Phytoplankton, Zooplankton, and Detritus (NPZD). Monthly mean wind forcings are adopted to force this MOM-NPZD model. For better prediction and analysis of N, P, Z and D distributions in the sea the model needs data assimilation from biomass observations on the sea surface. Chosen approach for evaluating performances of data assimilation techniques in coupled model is the definition of a twin experiment testbed where a reference run is carried out assuming its result as the truth. We define a sampling strategy to obtain different datasets to be incorporated in another ecological model in successive runs in order to appraise the potential of the data assimilation and sampling strategy. The runs carried out with different techniques and different spatio-temporal coverages are compared in order to evaluate the sensitivity to different coverage of dataset. The discussed alternative way is to assume the ecosystem at steady state and

    Using the most recent proper-motion determination of the old, solar-metallicity, Galactic open cluster M67 in orbital computations in a non-axisymmetric model of the Milky Way, including a bar and three-dimensional spiral arms, we explore the possibility that the Sun once belonged to this cluster. We have performed Monte Carlo numerical simulations to generate the present-day orbital conditions of the Sun and M67, and all the parameters in the Galactic model. We compute 3.5 × 105 pairs of orbits Sun-M67 looking for close encounters in the past with a minimum distance approach within the tidal radius of M67. In these encounters we find that the relative velocity between the Sun and M67 is larger than 20 km s-1. If the Sun had been ejected from M67 with this high velocity by means of a three-body encounter, this interaction would have either destroyed an initial circumstellar disk around the Sun or dispersed its already formed planets. We also find a very low probability, much lower than 10-7, that the Sun was ejected from M67 by an encounter of this cluster with a giant molecular cloud. This study also excludes the possibility that the Sun and M67 were born in the same molecular cloud. Our dynamical results convincingly demonstrate that M67 could not have been the birth cluster of our solar system. This work relies partly on observations of the Large Binocular Telescope (LBT). The LBT is an international collaboration among institutions in the United States, Italy, and Germany. LBT Corporation partners are The Ohio State University; The University of Arizona on behalf of the Arizona university system; Istituto Nazionale di Astrofisica, Italy; LBT Beteiligungsgesellschaft, Germany, representing the Max-Planck Society, the Astrophysical Institute Potsdam, and Heidelberg University; and The Research Corporation, on behalf of The University of Notre Dame, University of Minnesota, and University of Virginia.

    Rapid characterization of tephra during explosive eruptions can provide valuable insights into eruptive mechanisms, also integrating other monitoring systems. Here we reveal a perspective on Stromboli's conduit processes by linking ash textures to geophysical estimates of eruption parameters of observed explosions. A three day campaign at Stromboli was undertaken by Italy's Istituto Nazionale di Geofisica e Vulcanologia (INGV) in October 2009. At this time activity was moderately intense, with an average 4 to 5, both ash-rich and ash-poor, explosions per hour at each the SW and NE vents. A total of fifteen ash samples were collected in real time. We used binocular and scanning electron microscopes to analyze the components, grain size and morphology distributions, and surface chemistry of ash particles within eight selected samples. In addition, the INGV monitoring network provided visual, thermal, and seismic information on the explosions that generated the sampled ash. In each sample, the proportion of fluidal, glassy sideromelane (as opposed to blocky, microcrystalline tachylite plus lithics), the degree of "chemical freshness" (as opposed to chemical alteration), and the average size of particles appear to correlate directly with the maximum height and the seismic amplitude of the corresponding explosion, and inversely correlate with the amount of ash erupted, as estimated by monitoring videos. These observations suggest that more violent explosions (i.e., those driven by the release of larger and more pressurized gas volumes) produce ash via the fragmentation of hotter, more fluid magma, while weaker ones mostly erupt ash-sized particles derived by the fragmentation of colder magma and incorporation of conduit wall debris. The formation of fluidal ash particles (up to Pele's hairs) requires aerodynamic deformation of a relatively low-viscosity magma, in agreement with the strong acceleration imposed upon fragmented magma clots by the rapid expansion of

    The experimental characterization of the neutron fields produced as parasitic effect in medical accelerators is assuming an increased importance for either the patient protection or the facility design aspects. Medical accelerators are diverse in terms of particle type (electrons or hadrons) and energy, but the radiation fields around them have in common (provided that a given threshold energy is reached) the presence of neutrons with energy span over several orders of magnitude. Due to the large variability of neutron energy, field or dosimetry measurements in these workplaces are very complex, and in general, cannot be performed with ready-to-use commercial instruments. In spite of its poor energy resolution, the Bonner Sphere Spectrometer (BSS) is the only instrument able to simultaneously determine all spectral components in such workplaces. The energy range of this instrument is limited to E<20 MeV if only polyethylene spheres are used, but can be extended to hundreds of MeV by including metal-loaded spheres (extended range BSS, indicated with ERBSS). With the aim of providing useful data to the scientific community involved in neutron measurements at hadron therapy facilities, an ERBSS experiment was carried out at the Centro di AdroTerapia e Applicazioni Nucleari Avanzate (CATANA) of INFN-LNS (Laboratori Nazionali del Sud), where a proton beam routinely used for ophthalmic cancer treatments is available. The 62 MeV beam was directed towards a PMMA phantom, simulating the patient, and two neutron measurement points were established at 0{sup o} and 90{sup o} with respect to the beam-line. Here the ERBSS of UAB (Universidad Autonoma de Barcelona-Grup de Fisica de les Radiacions) and INFN (Istituto Nazionale di Fisica Nucleare-Laboratori Nazionali di Frascati) were exposed to characterize the 'forward' and 'sideward' proton-induced neutron fields.

    In Italy, since the 90s of the last century, researches concerning the contemporary stress field have been developing at Istituto Nazionale di Geofisica e Vulcanologia (INGV) with local and regional scale studies. Throughout the years many data have been analysed and collected: now they are organized and available for an easy end-use online. IPSI (Italian Present-day Stress Indicators) database, is the first geo-referenced repository of information on the crustal present-day stress field maintained at INGV through a web application database and website development by Gabriele Tarabusi. Data consist of horizontal stress orientations analysed and compiled in a standardized format and quality-ranked for reliability and comparability on a global scale with other database. Our first database release includes 855 data records updated to December 2015. Here we present an updated version that will be released in 2018, after new earthquake data entry up to December 2017. The IPSI web site (http://ipsi.rm.ingv.it/) allows accessing data on a standard map viewer and choose which data (category and/or quality) to plot easily. The main information of each single element (type, quality, orientation) can be viewed simply going over the related symbol, all the information appear by clicking the element. At the same time, simple basic information on the different data type, tectonic regime assignment, quality ranking method are available with pop-up windows. Data records can be downloaded in some common formats, moreover it is possible to download a file directly usable with SHINE, a web based application to interpolate stress orientations (http://shine.rm.ingv.it). IPSI is mainly conceived for those interested in studying the characters of Italian peninsula and surroundings although Italian data are part of the World Stress Map (http://www.world-stress-map.org/) as evidenced by many links that redirect to this database for more details on standard practices in this field.

    The Laboratorio Didattica e Divulgazione Scientifica of the Istituto Nazionale di Geofisica e Vulcanologia (INGV's Educational and Outreach Laboratory) organized activity with kids to convey scientific knowledge and to promote research on Earth Science, focusing on volcanic and seismic hazard. The combination of games and learning in educational activity can be a valuable tool for study of complex phenomena. Hands-on activity may help in engage kids in a learning process through direct participation that significantly improves the learning performance of children. Making learning fun motivate audience to pay attention on and stay focused on the subject. We present the experience of the hand-on laboratory "Laboratorio goloso per bambini curiosi di scienza (a delicious hands-on laboratory for kids curious about science)", performed in Frascati during the 2013 European Researchers' Night, promoted by the European Commission, as part of the program organized by the Laboratorio Didattica e Divulgazione Scientifica in the framework of Associazione Frascati Scienza (http://www.frascatiscienza.it/). The hand-on activity were designed for primary schools to create enjoyable and unusual tools for learning Earth Science. During this activity kids are involved with something related to everyday life, such as food, through manipulation, construction and implementation of simple experiments related to Earth dynamics. Children become familiar with scientific concepts such as composition of the Earth, plates tectonic, earthquakes and seismic waves propagation and experience the effect of earthquakes on buildings, exploring their important implications for seismic hazard. During the activity, composed of several steps, participants were able to learn about Earth inner structure, fragile lithosphere, waves propagations, impact of waves on building ecc.., dealing with eggs, cookies, honey, sugar, polenta, flour, chocolate, candies, liquorice sticks, bread, pudding and sweets.

    The knowledge of the places where we live comes both from the experience handed down from one generation to the other and from scientific knowledge. In some cases, natural risks are "invisible", such as earthquakes, in some other cases, natural risks are seemingly "invisible", such as a wall in danger of collapse or a valley in a flood zone. And besides all this, there is volcanic risk, where the power of the forces of nature appears in all its beauty and majesty. The possibility to see volcanoes, to perceive their changes, to observe them closely and the need to live with them, makes it very important for the population living in these areas to have an adequate knowledge of the risk, a knowledge that should be based on scientific research. In Italy the experience of the Istituto Nazionale di Geofisica e Vulcanologia in the Vesuvio area, in the Aeolian Islands and around Etna shows how vital it is to make people aware of volcanic risk. Thanks to the support of the scientific community, the population can develop the best possible coexistence with volcanoes and with the risk they represent. These are extreme situations, but they are the starting point for educational and informative activities continuing to evolve and upgrade in parallel to the availability of new technologies and media and the progress of research that INGV has been conducting for years through specific projects. The scientific community and individual researchers have the ethical duty to share with the community the knowledge on risk, a responsibility that becomes especially important in those areas affected by volcanic risk. It is from this educational action that depends on the awareness of the populations with regard to the risk they are exposed to, that results in a responsible behavior in case of emergency, and that becomes the main variable for the safety of communities coexisting with active volcanoes.

    Based only on weak-motion data, we carried out a combined study on region-specific source scaling and crustal attenuation in the Central Apennines (Italy). Our goal was to obtain a reappraisal of the existing predictive relationships for the ground motion, and to test them against the strong-motion data [peak ground acceleration (PGA), peak ground velocity (PGV) and spectral acceleration (SA)] gathered during the Mw 6.15 L'Aquila earthquake (2009 April 6, 01:32 UTC). The L'Aquila main shock was not part of the predictive study, and the validation test was an extrapolation to one magnitude unit above the largest earthquake of the calibration data set. The regional attenuation was determined through a set of regressions on a data set of 12 777 high-quality, high-gain waveforms with excellent S/N ratios (4259 vertical and 8518 horizontal time histories). Seismograms were selected from the recordings of 170 foreshocks and aftershocks of the sequence (the complete set of all earthquakes with ML≥ 3.0, from 2008 October 1 to 2010 May 10). All waveforms were downloaded from the ISIDe web page (), a web site maintained by the Istituto Nazionale di Geofisica e Vulcanologia (INGV). Weak-motion data were used to obtain a moment tensor solution, as well as a coda-based moment-rate source spectrum, for each one of the 170 events of the L'Aquila sequence (2.8 ≤Mw≤ 6.15). Source spectra were used to verify the good agreement with the source scaling of the Colfiorito seismic sequence of 1997-1998 recently described by Malagnini (2008). Finally, results on source excitation and crustal attenuation were used to produce the absolute site terms for the 23 stations located within ˜80 km of the epicentral area. The complete set of spectral corrections (crustal attenuation and absolute site effects) was used to implement a fast and accurate tool for the automatic computation of moment magnitudes in the Central Apennines.

    Full Text Available The analysis of geomagnetic field variations is a useful tool to detect electrical conductivity contrasts within the Earth. Lateral resolution of outlined patterns depends on the array dimensions and density of measurement sites over the investigated area. The inspection depth is constrained by the period of geomagnetic variations considered in data processing. Regions with significant geological features such as boundaries of continental plates, marginal areas of contact between tectonic units or other geodynamical processes, are of primary interest for the application of the MagnetoVariational (MV method. In the last ten years, in the frame of the ElectroMagnetic (EM sounding techniques in applied geophysics, this method has been applied in Italy by researchers of the Istituto Nazionale di Geofisica, Rome, the Dipartimento di Scienze della Terra, Universitá di Genova and the Czech Science Academy of Prague. The Ivrea body in the Northwestern Alps and their junction with the Apennine chain, the micro-plate of the Sardinian-Corsican system and, recently, the central part of the peninsula along Tyrrhenian-Adriatic lithospheric transects were investigated. Studies in time and frequency-domain used in the first investigations, have been followed by more refined analysis involving tests on the induced EM field dimension, computations of single site Transfer Functions (TFs through Parkinson arrows' and Fourier maps in the Hypothetical Event technique (HE. It was possible to describe the electrical conductivity distribution in the inner part of the SW Alpine arc and to confirm the presence of lithospheric and asthenospheric anomalies obtained by other geophysical methods. For the Sardinia-Corsica system, 2D and 3D inversion models highlighted the existence of two major conducting bodies, one north of Corsica, and the other south of Sardinia.

    To study the nature of the state Y (2175), a dedicated data set of e+e- collision data was collected at the center-of-mass energy of 2.125 GeV with the BESIII detector at the BEPCII collider. By analyzing large-angle Bhabha scattering events, the integrated luminosity of this data set is determined to be 108.49±0.02±0.85 pb-1, where the first uncertainty is statistical and the second one is systematic. In addition, the center-of-mass energy of the data set is determined with radiative dimuon events to be 2126.55±0.03±0.85 MeV, where the first uncertainty is statistical and the second one is systematic.

  4. La letteratura italiana tradotta in Argentina

    Full Text Available In due secoli di storia della letteratura argentina, lo sviluppo della letteratura italiana tradotta è in stretto rapporto con i propositi pedagogici o estetici determinati dal contesto culturale dei diversi momenti storici. In linea di massima, è possibile affermare che, dalla conformazione dello Stato nazionale e durante i primi decenni del XX secolo, la traduzione letteraria mirava ad ampliare l’orizzonte culturale di un lettore che si consolidava al ritmo della fiammante nazione. Nelle fasi successive e in stretto rapporto con la politica culturale portata avanti da Victoria Ocampo a partire dal 1931 tramite la rivista Sur e il suo posteriore progetto editoriale, la traduzione è stata soprattutto una pratica di scrittura che ebbe un’influenza decisiva nell’ordito della letteratura nazionale favorendo il suo rinnovo e incentivando le versioni di traduttori argentini. Fu questa un’apertura che favorì, durante la seconda metà del secolo, nel contesto della ricezione della letteratura universale, l’ingresso della letteratura italiana in Argentina. Il presente lavoro tratta in maniera sistematica, ma provvisoria, il panorama della letteratura italiana tradotta in Argentina. Lo scopo principale comporta il registro dei momenti più fecondi e l’interpretazione degli esiti ottenuti nei confronti della traduzione nel sistema letterario nazionale.

    2003-04-01

    The experimental Nuclear Physics activity of the Italian researchers is briefly reviewed. The experiments, that are financially supported by the INFN, are done in strict collaboration by more than 500 INFN and University researchers. The experiments cover all the most important field of the modern Nuclear Physics with probes extremely different in energy and interactions. Researches are done in all the four National Laboratories of the INFN even if there is a deeper involvement of the two national laboratories expressly dedicated to Nuclear Physics: the LNL (Laboratorio Nazionale di Legnaro) and LNS (Laboratorio Nazionale del Sud) where nuclear spectroscopy and reaction dynamics are investigated. All the activities with electromagnetic probes develops in abroad laboratories as TJNAF, DESY, MAMI, ESFR and are dedicated to the studies of the spin physics and of the nucleon resonance; hypernuclear and kaon physics is investigated at LNF. A strong community of researchers work in the relativistic and ultra-relativistic heavy ions field in particular at CERN with the SPS Pb beam and in the construction of the ALICE detector for heavy-ion physics at the LHC collider. Experiments of astrophysical interest are done with ions of very low energy; in particular the LUNA accelerator facility at LNGS (Laboratorio Nazionale del Gran Sasso) succeeded measuring cross section at solar energies, below or near the solar Gamow peak. Interdisciplinary researches on anti-hydrogen atom spectroscopy and on measurements of neutron cross sections of interest for ADS development are also supported.

  20. Swift: 10 Years of Discovery

    2014-12-01

    The conference Swift: 10 years of discovery was held in Roma at La Sapienza University on Dec. 2-5 2014 to celebrate 10 years of Swift successes. Thanks to a large attendance and a lively program, it provided the opportunity to review recent advances of our knowledge of the high-energy transient Universe both from the observational and theoretical sides. When Swift was launched on November 20, 2004, its prime objective was to chase Gamma-Ray Bursts and deepen our knowledge of these cosmic explosions. And so it did, unveiling the secrets of long and short GRBs. However, its multi-wavelength instrumentation and fast scheduling capabilities made it the most versatile mission ever flown. Besides GRBs, Swift has observed, and contributed to our understanding of, an impressive variety of targets including AGNs, supernovae, pulsars, microquasars, novae, variable stars, comets, and much more. Swift is continuously discovering rare and surprising events distributed over a wide range of redshifts, out to the most distant transient objects in the Universe. Such a trove of discoveries has been addressed during the conference with sessions dedicated to each class of events. Indeed, the conference in Rome was a spectacular celebration of the Swift 10th anniversary. It included sessions on all types of transient and steady sources. Top scientists from around the world gave invited and contributed talks. There was a large poster session, sumptuous lunches, news interviews and a glorious banquet with officials attending from INAF and ASI. All the presentations, as well as several conference pictures, can be found in the conference website (http://www.brera.inaf.it/Swift10/Welcome.html). These proceedings have been collected owing to the efforts of Paolo D’Avanzo who has followed each paper from submission to final acceptance. Our warmest thanks to Paolo for all his work. The Conference has been made possible by the support from La Sapienza University as well as from the ARAP

    Full Text Available Political leadership in Italy in the light of the national comical traditionThis essay deals with humour and satire in politics. The issue of humour is contextualized within a wider cultural phenomenon called ‘show civilisation’ or ‘schermopolis’, i.e. the pervasiveness of screens in our everyday life. In doing so I will consider the role of new media and social networks in fostering the use of humour in political discourse. Next I will try to find a new framework for forms of popularity in politics by adapting to the current conjuncture the definitions given by Eric Landowsky at the end of the 1980s. Nowadays the politician-vedette is indeed the most popular form within the show civilisation phenomenon mentioned above. I will demonstrate that some Italian versions of this figure seem inspired by a rich Italian Comedy tradition. Finally, I will propose a number of hypotheses about the ways in which leaders obtain electoral consensus, for example through physical attractiveness, sympathy, and their ability to amuse people. In this perspective, a leader who is good for a laugh seems automatically a good leader.

    The idea of organizing a symposium on mathematical models in biology came to some colleagues, members of the Accademia dei Lincei, in order to point out the importance of mathematics not only for supplying instruments for the elaboration and the evaluation of experimental data, but also for discussing the possibility of developing mathematical formulations of biological problems. This appeared particularly appropriate for genetics, where mathematical models have been of historical importance. When the organizing work had started, it became clear to us that the classic studies of Vito Volterra (who was also a Member of the Academy and its President from 1923 to 1926) might be con­ sidered a further reason to have the meeting in Rome at the Accademia dei Lincei; thus the meeting is dedicated to his memory. Biology, in its manifold aspects proved to Se ~ difficult object for an exhaustive approach; thus it became necessary for practical reasons to make a choice of problems. Therefore not all branches of biology...

Madonna Consiglio Nazionale delle Ricerche, Istituto di Metodologie per l'Analisi Ambientale (CNR-IMAA), Tito Scalo, Potenza, Italy Information about the amount and spatial distribution of atmospheric water vapor is essential to improve our knowledge of weather forecasting and climate change. Water vapor is highly variable in space and time depending on the complex interplay of several phenomena like convection, precipitation, turbulence, etc. It remains one of the most poorly characterized meteorological parameters. Remarkable progress in using of Global Navigation Satellite Systems (GNSS), in particular GPS, for the monitoring of atmospheric water vapor has been achieved during the last decades. Various studies have demonstrated that GPS could provide accurate water vapor estimates for the study of the atmosphere. Different GPS data processing provided within the scientific community made use of various tropospheric models that primarily differs for the assumptions on the vertical refractivity profiles and the mapping of the vertical delay with elevation angles. This works compares several models based on the use of surface meteorological data. In order to calculate the Integrated Water Vapour (IWV), an algorithm for calculating the zenith tropospheric delay was implemented. It is based upon different mapping functions (Niell, Saastamoinen, Chao and Herring Mapping Functions). Observations are performed at the Istituto di Metodologie per l'Analisi Ambientale (IMAA) GPS station located in Tito Scalo, Potenza (40.60N, 15.72E), from July to December 2014, in the framework of OSCAR project (Observation System for Climate Application at Regional scale).

    ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) is a Flagship Project funded by the Italian Ministry of Education, University and Research, and led by INAF, the Italian National Institute of Astrophysics. Within this framework, INAF is currently developing an end-to-end prototype, named ASTRI SST-2M, of a Small Size Dual-Mirror Telescope for the Cherenkov Telescope Array, CTA. A second goal of the project is the realization of the ASTRI/CTA mini-array, which will be composed of seven SST-2M telescopes placed at the CTA Southern Site. The ASTRI Mini Array Software System (MASS) is designed to support the ASTRI/CTA mini-array operations. MASS is being built on top of the ALMA Common Software (ACS) framework, which provides support for the implementation of distributed data acquisition and control systems, and functionality for log and alarm management, message driven communication and hardware devices management. The first version of the MASS system, which will comply with the CTA requirements and guidelines, will be tested on the ASTRI SST-2M prototype. In this contribution we present the interface definitions of the MASS high level components in charge of the ASTRI SST-2M observation scheduling, telescope control and monitoring, and data taking. Particular emphasis is given to their potential reuse for the ASTRI/CTA mini-array.

    Binary stars hosting exoplanets are a unique laboratory where chemical tagging can be performed to measure the elemental abundances of both stellar components with high accuracy, with the aim to investigate the formation of planets and their subsequent evolution. Here, we present a high-precision differential abundance analysis of the XO-2 wide stellar binary based on high-resolution HARPS-N at TNG spectra. Both components are very similar K-dwarfs and host planets. Since they formed presumably within the same molecular cloud, we expect that they possess the same initial elemental abundances. We investigated whether planets can cause some chemical imprints in the stellar atmospheric abundances. We measure abundances of 25 elements for both stars with a range of condensation temperature TC = 40-1741 K, achieving typical precisions of ~0.07 dex. The northern component shows abundances in all elements higher by +0.067 ± 0.032 dex on average, with a mean difference of +0.078 dex for elements with TC > 800 K. The significance of the XO-2N abundance difference relative to XO-2S is at the 2σ level for almost all elements. We discuss that this result might be interpreted as the signature of the ingestion of material by XO-2N or depletion in XO-2S that is due to locking of heavy elements by the planetary companions. We estimate a mass of several tens of M⊕ in heavy elements. The difference in abundances between XO-2N and XO-2S shows a positive correlation with the condensation temperatures of the elements, with a slope of (4.7 ± 0.9) × 10-5 dex K-1, which could mean that both components have not formed terrestrial planets, but first experienced the accretion of rocky core interior to the subsequent giant planets.

    Recently the Italian Department of Civil Protection (DPC), in cooperation with Istituto Nazionale di Geofisica e Vulcanologia (INGV) has promoted the 'S2' research project (http://nuovoprogettoesse2.stru.polimi.it/) aimed at the design, testing and application of an open-source code for seismic hazard assessment (SHA). The tool envisaged will likely differ in several important respects from an existing international initiative (Open SHA, Field et al., 2003). In particular, while "the OpenSHA collaboration model envisions scientists developing their own attenuation relationships and earthquake rupture forecasts, which they will deploy and maintain in their own systems", the main purpose of S2 project is to provide a flexible computational tool for SHA, primarily suited for the needs of DPC, which not necessarily are scientific needs. Within S2, a crucial issue is to make alternative approaches available to quantify the ground motion, with emphasis on the near field region. The SHA architecture envisaged will allow for the use of ground motion descriptions other than those yielded by empirical attenuation equations, for instance user generated motions provided by deterministic source and wave propagation simulations. In this contribution, after a brief presentation of Project S2, we intend to illustrate some preliminary 3D scenario simulations performed in the alluvial basin of Sulmona (Central Italy), as an example of the type of descriptions that can be handled in the future SHA architecture. In detail, we selected some seismogenic sources (from the DISS database), believed to be responsible for a number of destructive historical earthquakes, and derive from them a family of simplified geometrical and mechanical source models spanning across a reasonable range of parameters, so that the extent of the main uncertainties can be covered. Then, purely deterministic (for frequencies Journal of Seismology, 1, 237-251. Field, E.H., T.H. Jordan, and C.A. Cornell (2003

    In the last years, it has been recognized the importance of using microseismic activity data to gain information on the state and dynamics of a reservoir, notwithstanding the difficulties of recording, localizing the events, interpret them correctly, in terms of developing fractures, or thermal effects. The increasing number of CO2 storage experiments, with the necessity of providing efficient, economic, and long-term monitoring methods, both in the injection and post-injection phases, further encourage the development and improvement of recording and processing techniques. Microseismic signals are typically recorded with downhole sensors. Monitoring with surface sensors is problematic due to increased noise levels and signal attenuation particularly in the near surface. The actual detection distance depends on background noise conditions, seismic attenuation and the microseismic source strength. In the frame of the European project Co2ReMoVe and of the European Network of Excellence Co2GeoNet, a passive seismic experiment was planned in the Ketzin site for geological storage of CO2, a former gas store near Potsdam, object of the CO2SINK European project and inserted also in the European project Co2ReMoVe. Aim of the survey is to complement the CO2-SINK active seismic downhole experiments, adding precious information on the microseismicity induced by stress field changes at the reservoir level and in the overburden, due to the CO2 injection. The baseline survey was done in May 2008 by the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale-OGS (Italy), with the support of the Deutsches GeoForschungsZentrum-GFZ (Germany) and the collaboration of the Institut für Geowissenschaftliche Gemeinschaftsaufgaben-GGA (Germany), shortly before the starting of the CO2 injection (June 30th 2008). A continuous monitoring (about 5 days) was performed by 2 downhole 3C geophones, and 3 surface 3C geophones located around the wells. This paper, based on the analysis of

    The experience of collection of data on earthquake effects and diffusion of information to people, carried on through the site "haisentitoilterremoto.it" (didyoufeelit) managed by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), has evidenced a constantly growing interest by Italian citizens. Started in 2007, the site has collected more than 520,000 compiled intensity questionnaires, producing intensity maps of almost 6,000 earthquakes. One of the most peculiar feature of this experience is constituted by a bi-directional information exchange. Every person can record observed effects of the earthquake and, at the same time, look at the generated maps. Seismologists, on the other side, can find each earthquake described in real time through its effects on the whole territory. In this way people, giving punctual information, receive global information from the community, mediated and interpreted by seismological knowledge. The relationship amongst seismologists, mass media and civil society is, thus, deep and rich. The presence of almost 20,000 permanent subscribers distributed on the whole Italian territory, alerted in case of earthquake, has reinforced the participation: the subscriber is constantly informed by the seismologists, through e-mail, about events occurred in his-her area, even if with very small magnitude. The "alert" service provides the possibility to remember that earthquakes are a phenomenon continuously present, on the other hand it shows that high magnitude events are very rare. This kind of information is helpful as it is fully complementary to that one given by media. We analyze the effects of our activity on society and mass media. The knowledge of seismic phenomena is present in each person, having roots on fear, idea of death and destruction, often with the deep belief of very rare occurrence. This position feeds refusal and repression. When a strong earthquake occurs, surprise immediately changes into shock and desperation. A

    A new system for acquiring and processing digital signals has been developed in the last few years at the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The system makes extensive use of the internet communication protocol standards such as TCP and UDP which are used as the transport highway inside the Italian network, and possibly in a near future outside, to share or redirect data among processes. The Italian National Seismic Network has been working for about 18 years equipped with vertical short period seismometers and transmitting through analog lines, to the computer center in Rome. We are now concentrating our efforts on speeding the migration towards a fully digital network based on about 150 stations equipped with either broad band or 5 seconds sensors connected to the data center partly through wired digital communication and partly through satellite digital communication. The overall process is layered through intranet and/or internet. Every layer gathers data in a simple format and provides data in a processed format, ready to be distributed towards the next layer. The lowest level acquires seismic data (raw waveforms) coming from the remote stations. It handshakes, checks and sends data in LAN or WAN according to a distribution list where other machines with their programs are waiting for. At the next level there are the picking procedures, or "pickers", on a per instrument basis, looking for phases. A picker spreads phases, again through the LAN or WAN and according to a distribution list, to one or more waiting locating machines tuned to generate a seismic event. The event locating procedure itself, the higher level in this stack, can exchange information with other similar procedures. Such a layered and distributed structure with nearby targets allows other seismic networks to join the processing and data collection of the same ongoing event, creating a virtual network larger than the original one. At present we plan to cooperate with other

    The plate boundary between Africa and Eurasia represents an interesting geodynamical region characterized by a complex pattern of deformation. First-order scientific problems regarding the existence of rigid blocks within the plate boundary, the present-day activity of the Calabrian subduction zone and the modes of release of seismic deformation are still awaiting for a better understanding. To address these issues, the INGV (Istituto Nazionale Geofisica e Vulcanlogia) deployed a permanent, integrated and real-time monitoring GPS network (RING) all over Italy. RING is now constituted by about 120 stations. The CGPS sites, acquiring at 1Hz and 30s sampling rate, are integrated either with broad band or very broad band seismometers and accelerometers for an improved definition of the seismically active regions. Most of the sites are connected to the acquisition centre (located in Rome and duplicated in Grottaminarda) through a satellite system (VSAT), while the remaining sites transmit data by Internet and classical phone connections. The satellite data transmission and the integration with seismic instruments makes this network one of the most innovative CGPS networks in Europe. The heterogeneity of the installed instrumentation, the transmission types and the increasing number of stations needed a central monitoring and acquisition system. A central acquisition system has been developed in Grottaminarda in southern Italy. Regarding the seismic monitoring we chose to use the open source system Earthworm, developed by USGS, with which we store waveforms and implement automatic localization of the seismic events occurring in the area. As most of the GPS sites are acquired by means of Nanometrics satellite technology, we developed a specific software (GpsView), written in Java, to monitor the state of health of those CGPS. This software receives GPS data from NaqsServer (Nanometrics acquisition system) and outputs information about the sites (i.e. approx position

    2012-09-01

    With the goal of constructing a homogeneous data set of moment magnitudes (Mw) to be used for seismic hazard assessment, we compared Mw estimates from moment tensor catalogues available online. We found an apparent scaling disagreement between Mw estimates from the National Earthquake Information Center (NEIC) of the US Geological Survey and from the Global Centroid Moment Tensor (GCMT) project. We suspect that this is the effect of an underestimation of Mw > 7.0 (M0 > 4.0 × 1019 Nm) computed by NEIC owing to the limitations of their computational approach. We also found an apparent scaling disagreement between GCMT and two regional moment tensor catalogues provided by the 'Eidgenössische Technische Hochschule Zürich' (ETHZ) and by the European-Mediterranean Regional Centroid Moment Tensor (RCMT) project of the Italian 'Istituto Nazionale di Geofisica e Vulcanologia' (INGV). This is probably the effect of the overestimation of Mw < 5.5 (M0 < 2.2 × 1017 Nm), up to year 2002, and of Mw < 5.0 (M0 < 4.0 × 1016 Nm), since year 2003, owing to the physical limitations of the standard CMT inversion method used by GCMT for the earthquakes of relatively low magnitude. If the discrepant data are excluded from the comparisons, the scaling disagreements become insignificant in all cases. We observed instead small absolute offsets (≤0.1 units) for NEIC and ETHZ catalogues with respect to GCMT whereas there is an almost perfect correspondence between RCMT and GCMT. Finally, we found a clear underestimation of about 0.2 units of Mw magnitudes computed at the INGV using the time-domain moment tensor (TDMT) method with respect to those reported by GCMT and RCMT. According to our results, we suggest appropriate offset corrections to be applied to Mw estimates from NEIC, ETHZ and TDMT catalogues before merging their data with GCMT and RCMT catalogues. We suggest as well to discard the probably discrepant data from NEIC and GCMT if other Mw estimates from different sources are

    In recent years the Earth Sciences community is facing the need to achieve a more effective and efficient dissemination of its scientific culture. There is now a growing needing to integrate the use of "traditional" dissemination media of cultural heritage with the new digital technologies. Getting people involved in geoheritage site's activities represents a crucial issue in order to better communicate and increase the collective awareness of natural hazards, risk, and environmental change. The Reale Osservatorio Vesuviano (ROV) which is part of the Istituto Nazionale di Geofisica e Vulcanologia (INGV), owns collections unique in their combination of scientific, historical and artistic importance. The long history of ROV is extensively documented in its collections. This heritage - of great scientific and cultural value and unique for its abundance and variety - tells the story of the first observatory in the world, closely linked to the activity of Vesuvius, and the commitment of many scientists who dedicated their lives to study the volcano. The collections include: a) old books on volcanological matters, b) collection of rocks, minerals, volcanic ash and other materials from historical eruptions of Vesuvius, c) recordings on smoked paper of Vesuvius seismic activity from 1915 until 1970, d) scientific instruments, e) geological and geomorphological maps and models, f) vintage photographs and filmed sequences of eruptions, g) gouaches of Vesuvius and h) lava medals. The exposition of these collections, improved with the new digital contents, may trace new and unexplored routes for the dissemination of Earth Sciences related culture. The ethical duty of the ROV is the creation of an universal identity by taking a picture of the evolution of the society through the training of the culture of seismic and volcanic risk. A disappearance of its heritage could represent an huge impoverishment of its community: the ROV carries in fact the cultural identity of the

    The Istituto Nazionale di Geofisica e Vulcanologia (INGV) is currently the largest European scientific institution dealing with Earth Sciences research and real-time surveillance, early warning, and forecast activities in geophysics and volcanology. The Laboratorio Didattica e Divulgazione Scientifica of INGV organizes every year educational and outreach activities with schools of different levels and with general public to convey scientific knowledge and to promote the Research on Earth Science, focusing on volcanic and seismic hazard. Among the most successful initiatives is the creation of a calendar designed for the schools and realized based on a competition devoted to children of primary school. The intent is to provide a pleasant stimulus for discussion for teachers and students. Schools participate with enthusiasm by sending drawings made by children on a specified theme, different each year, chosen among geophysics and earth sciences arguments. For 2011, the theme was selected also with the aims to investigate on the image the young generations have of the Research and on its potential and future prospective. The title was "Scienziato anche io! La Scienza e gli scienziati visti dai bambini" (I'm a scientist too! Science and scientists from the children point of view), with the purpose of give a shape to the image children have of the world of science, its potential and the figure of the scientists. We asked the children to realized a draw suggesting some possible arguments between: 1. How do you imagine a scientist? How do you imagine the daily activities of a researcher? 2. What is the invention you consider the most important among all those you know? 3. What would you invent? The 986 drawings realized by 6 up to 10 years old boys and girls from 48 schools distributed throughout the Italian territory, report us a generally positive picture of the work of scientists and also highlight a great level of confidence in the potential of science, capable to

    Aims: We present a deep multiwavelength imaging survey (UGR) in 3 different fields, Q0933, Q1623, and COSMOS, for a total area of ~1500 arcmin2. The data were obtained with the Large Binocular Camera on the Large Binocular Telescope. Methods: To select our Lyman-break galaxy (LBG) candidates, we adopted the well established and widely used color-selection criterion (U - G vs. G - R). One of the main advantages of our survey is that it has a wider dynamic color range for U-dropout selection than in previous studies. This allows us to fully exploit the depth of our R-band images, obtaining a robust sample with few interlopers. In addition, for 2 of our fields we have spectroscopic redshift information that is needed to better estimate the completeness of our sample and interloper fraction. Results: Our limiting magnitudes reach 27.0(AB) in the R band (5σ) and 28.6(AB) in the U band (1σ). This dataset was used to derive LBG candidates at z ≈ 3. We obtained a catalog with a total of 12 264 sources down to the 50% completeness magnitude limit in the R band for each field. We find a surface density of ~3 LBG candidates arcmin-2 down to R = 25.5, where completeness is ≥95% for all 3 fields. This number is higher than the original studies, but consistent with more recent samples. Observations were carried out using the Large Binocular Telescope at Mt. Graham, AZ. The LBT is an international collaboration among institutions in the United States, Italy, and Germany. LBT Corporation partners are The University of Arizona on behalf of the Arizona university system; Istituto Nazionale di Astrofisica, Italy; LBT Beteiligungsgesellschaft, Germany, representing the Max-Planck Society, the Astrophysical Institute Potsdam, and Heidelberg University; The Ohio State University; and The Research Corporation, on behalf of The University of Notre Dame, University of Minnesota, and University of Virginia.Full Tables A.1-A.3 are only available at the CDS via anonymous ftp to http

    The Reale Osservatorio Vesuviano (ROV), historic home of the Istituto Nazionale di Geofisica e Vulcanologia (INGV), is the oldest volcanological observatory in the world. It was founded in 1841 by the Bourbon king of Naples. The building is located on the western slope of Mount Vesuvius, one of the most famous and dangerous volcanoes in the world. Since its foundation, the ROV has always attracted researchers, visitors and students from many countries. The ROV site is an elegant neo-classical building which at present hosts permanent exhibitions of part of its inheritance of valuable mineral, scientific instrument and art collections. A radical change is now under way, starting with the structural reinforcement of the building, renewal and upgrading of services, and the redefinition of exhibition itineraries so as to make visits still more enjoyable and informative. This will include the integration of outdoor footpaths and theme-based routes designed for users of differing levels of expertise. This major transformation also involves a study and a number of operations aimed at the possibility of developing self-financed activities. To this end an analysis of tourist movements in Campania was conducted, in part so as to attract to the ROV a larger and more varied group of visitors. In an area that - despite its unique characteristics - is currently significantly degraded and underused, the creation of such a powerful tourist and cultural attraction would serve as a focus for the development of additional activities and services that would greatly enhance it and stimulate growth. These activities would, of course, be compatible with a territory that has a high risk of volcanic hazards - indeed, such growth would constitute an important component in mitigating this risk in the area. The example given illustrates how the restoration and enhancement of a piece of our historic, scientific and cultural heritage could be the driving force behind the economic revival of an

Aim. We provide a homogeneous library of high-resolution, high-S/N spectra for 48 bright AFGKM stars, some of them approaching the quality of solar-flux spectra. Our sample includes the northern Gaia benchmark stars, some solar analogs, and some other bright Morgan-Keenan (M-K) spectral standards. Methods: Well-exposed deep spectra were created by average-combining individual exposures. The data-reduction process relies on adaptive selection of parameters by using statistical inference and robust estimators. We employed spectrum synthesis techniques and statistics tools in order to characterize the spectra and give a first quick look at some of the science cases possible. Results: With an average spectral resolution of R ≈ 220 000 (1.36 km s-1), a continuous wavelength coverage from 383 nm to 912 nm, and S/N of between 70:1 for the faintest star in the extreme blue and 6000:1 for the brightest star in the red, these spectra are now made public for further data mining and analysis. Preliminary results include new stellar parameters for 70 Vir and α Tau, the detection of the rare-earth element dysprosium and the heavy elements uranium, thorium and neodymium in several RGB stars, and the use of the 12C to 13C isotope ratio for age-related determinations. We also found Arcturus to exhibit few-percent Ca II H&K and Hα residual profile changes with respect to the KPNO atlas taken in 1999.

    During a 12 months period (November 1992-October 1993) were collected samples of atmospheric depositions (open field, throughfall and stem flow) in a beechwood located in the central Apennine, far from pollution sources. The nutritional status of leaves and the fertility of the soil were also analysed. Results show only few acidic episodes, due to a long range atmospheric transport. Many cations, mainly potassium, are leached from the leaves, but their uptake by roots is very quick; the leaching occurs during the foliar growth rather than the senescence period. No stress symptoms have been observed in the leaves. During the winter months the branchlets also keep and filter the rain. The throughfall is usually less acidic than the open field depositions; whereas the stem flow carries much more acidity to the soil. Sea salt is one of the main component of the deposition chemistry, and likely it has an impact on the ecosystem. Deposition of anthropogenic elements as nitrogen and sulphur are quite little. [Italiano] Nel periodo Novembre 1992-Ottobre 1993 e` stata effettuata una campagna di campionamento delle deposizioni atmosferiche (acque raccolte in area coperta, sottochioma, e come scorrimento sul fusto) in una faggeta del Parco nazionale d`Abruzzo, localizzata lontano da pressione antropica e da fonti dirette d`inquinamento. Nel contempo sono stati analizzzati i parametri chimici e morfologici delle foglie di faggio e lo stato nutrizionale del suolo. I risultati indicano che, pur in presenza di limitati episodi di acidificazione dovuti al trasporto di inquinanti sulla lunga distanza, lo stato dell`ecosistema e` sostanzialmente buono. Gli elementi liscivati dalle chiome (soprattutto il potassio) vengono prontamente recuperati dalle radici e non sono state rilevate condizioni di stress. La liscivazione degli elementi avviene nel periodo di crescita e sviluppo delle foglie, piuttosto che in quello della loro senescenza. L`azione di trattenuta e filtraggio delle

    The Italian National Institute for Astrophysics (INAF) is leading the Astrofisica con Specchi a Tecnologia Replicante Italiana (ASTRI) project whose main purpose is the realization of small size telescopes (SST) for the Cherenkov Telescope Array (CTA). The first goal of the ASTRI project has been the development and operation of an innovative end-to-end telescope prototype using a dual-mirror optical configuration (SST-2M) equipped with a camera based on silicon photo-multipliers and very fast read-out electronics. The ASTRI SST-2M prototype has been installed in Italy at the INAF "M.G. Fracastoro" Astronomical Station located at Serra La Nave, on Mount Etna, Sicily. This prototype will be used to test several mechanical, optical, control hardware and software solutions which will be used in the ASTRI mini-array, comprising nine telescopes proposed to be placed at the CTA southern site. The ASTRI mini-array is a collaborative and international effort led by INAF and carried out by Italy, Brazil and South-Africa. We present here the use cases, through UML (Unified Modeling Language) diagrams and text details, that describe the functional requirements of the software that will manage the ASTRI SST-2M prototype, and the lessons learned thanks to these activities. We intend to adopt the same approach for the Mini Array Software System that will manage the ASTRI miniarray operations. Use cases are of importance for the whole software life cycle; in particular they provide valuable support to the validation and verification activities. Following the iterative development approach, which breaks down the software development into smaller chunks, we have analysed the requirements, developed, and then tested the code in repeated cycles. The use case technique allowed us to formalize the problem through user stories that describe how the user procedurally interacts with the software system. Through the use cases we improved the communication among team members, fostered

    The Cherenkov Telescope Array (CTA) observatory will represent the next generation of Imaging Atmospheric Cherenkov Telescope. Using a combination of large-, medium-, and small-scale telescopes (LST, MST, SST, respectively), it will explore the Very High Energy domain from a few tens of GeVup to about few hundreds of TeV with unprecedented sensitivity, angular resolution and imaging quality. In this framework, the Italian ASTRI program, led by the Italian National Institute of Astrophysics (INAF) developed a 4-meter class telescope, which will adopt an aplanatic, wide-field, double-reflection optical layout in a Schwarzschild- Couder configuration. Within this program INAF assigned to the consortium between Galbiati Group and EIE Group the construction, assembly and tests activities of the prototype named ASTRI SST-2M. On the basis of the lesson learnt from the prototype, other telescopes will be produced, starting from a re-design phase, in order to optimize performances and the overall costs and production schedule for the CTA-SST telescope. This paper will firstly give an overview of the concept for the SST prototype mount structure. In this contest, the technologies adopted for the design, manufacturing and tests of the entire system will be presented. Moreover, a specific focus on the challenges of the prototype and the strategies associated with it will be provided, in order to outline the near future performance goals for this type of Cherenkov telescopes employed for Gamma ray science.

    ASTRI is an on-going project developed in the framework of the Cherenkov Telescope Array (CTA). An end- to-end prototype of a dual-mirror small-size telescope (SST-2M) has been installed at the INAF observing station on Mt. Etna, Italy. The next step is the development of the ASTRI mini-array composed of nine ASTRI SST-2M telescopes proposed to be installed at the CTA southern site. The ASTRI mini-array is a collaborative and international effort carried on by Italy, Brazil and South-Africa and led by the Italian National Institute of Astrophysics, INAF. To control the ASTRI telescopes, a specific ASTRI Mini-Array Software System (MASS) was designed using a scalable and distributed architecture to monitor all the hardware devices for the telescopes. Using code generation we built automatically from the ASTRI Interface Control Documents a set of communication libraries and extensive Graphical User Interfaces that provide full access to the capabilities offered by the telescope hardware subsystems for testing and maintenance. Leveraging these generated libraries and components we then implemented a human designed, integrated, Engineering GUI for MASS to perform the verification of the whole prototype and test shared services such as the alarms, configurations, control systems, and scientific on-line outcomes. In our experience the use of code generation dramatically reduced the amount of effort in development, integration and testing of the more basic software components and resulted in a fast software release life cycle. This approach could be valuable for the whole CTA project, characterized by a large diversity of hardware components.

  13. DALLA MANO AL VIDEO. ESPERIENZE E OSSERVAZIONI DI COSTRUZIONE DEL PENSIERO ASTRATTO, ANALITICO E COMPUTAZIONALE NELLA FORMAZIONE LINGUISTICA DELLA SCUOLA PRIMARIA

    Full Text Available In questo articolo viene illustrata la ricerca effettuata nell’arco di un anno scolastico in due scuole primarie del Comune di  Milano (l’Istituto Maria Consolatrice e l’Istituto Regina Mundi, dove sono stati sperimentati diversi metodi didattici con l’obiettivo di favorire la formazione delle competenze di analisi, astrazione e pensiero computazionale in contesti reali di programmazione del computer e robotica educativa. Le osservazioni mostrano come la centralità dell’uso evoluto della lingua sia il cardine nello sviluppo di competenze di tipo “pensiero computazionale”. In particolare l’elemento chiave che emerge nella ricerca è rappresentato  dall’osservazione della forte correlazione tra lo sviluppo delle capacità motorie fini della mano, lo sviluppo delle competenze linguistiche evolute e le competenze di pensiero complesso quali la capacità di astrazione nella descrizione di modelli reali e immaginari. La capacità di astrazione costituisce infatti la base della capacità di risoluzione di problemi e soprattutto della capacità di generare idee originali e creative, obiettivo di apprendimento primario della sperimentazione e del relativo processo di analisi di cui è stata oggetto. A seguire vengono quindi illustrati gli strumenti metodologici utilizzati, la loro modalità di valutazione; si preciserà quindi come l’uso della lingua contribuisca a potenziare e a sostenere il raggiungimento degli obbiettivi di apprendimento.   From the hand to video. Experiences and the construction of abstract, analytical and computational thought in primary school language education  This article presents research carried out in two primary schools in the city of Milan (Istituto Maria Consolatrice and Istituto Regina Mundi, where different teaching methods were implemented with the aim of encouraging the development of analytical, abstract and computational thinking skills in computer programming and educational robotics

    The coastal areas of the Southern Adriatic Sea, in particular the Apulian ones, may be considered an example of intact ecosystem and represent an ideal term of comparison to other marine ecosystems having higher levels of pollution (Northern Adriatic Sea). In order to evaluate the sanitary levels of this environment, four transect were investigated during two years monitoring (April 1995-March 1997) along the Otranto Channel coasts, by joint research groups of the Environmental Hygiene Laboratory of the Istituto Superiore di Sanita' and the Istituto Sperimentale Talassografico A. Cerruti of CNR in Taranto. The study underlines the phytoplanktic and bacterial population dynamics, and the detection of the microbiological water quality along the coast tract Brindisi-Lecce-Otranto-S. Maria di Leuca. The results acquired pointed out population dynamics of some potantially toxic species of Dinophysis genus and Pseudo-nitzschia delicatissima. These depended on the winter nutrient loads due to the ASW (Adriatic Superficial Waters) and to the LIW (Levantine Intermediate Waters). The bacterial community was mainly constituted by genera Aeromonas, Photobacterium, Cytophaga and Pseudomonas. Also the presence of Enterobacteriaceae family was relevant. Among the pathogenic vibrios the most frequently isolated species were Vibrio alginolyticus and Vibrio vulnificus. [Italian] Considerando che le zone del basso Adriatico, in particolare quelle pugliesi, costituiscono un biotopo ancora relativamente inalterato, esse sono state oggetto di un'indagine sperimentale condotta in 24 mesi di attivita' (aprile 1995-marzo 1997) lungo le coste del Canale di Otranto, ad opera di un gruppo congiunto del Laboratorio di Igiene Ambientale dell'Istituto Superiore di Sanita' e dei laboratori dell'Istituto Sperimentale Talassografico A. Cerruti del CNR di Taranto, ai fini di valutare lo stato di salute di questo ambiente, che fornisce, con buona probabilita', un
