    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.

    The Current Research Information System of the Istituto Nazionale di Astrofisica (CRIS-INAF) is an institutional database for the entire scientific and technological output of INAF's staff, which consists of more than 2000 people. It was set up in 2009 in order to provide real-time information and statistics on the global activity of the Institute. The system — which offers the widest global coverage of INAF's research output as compared to other relevant commercial or institutional databases — is the result of the co-operation among four main sets of actors: information technologists, for system development; librarians/documentalists, who provide expertise in library science; administrative personnel, for central and local management of staff and structures; and researchers, mainly for data provision and validation. The original design, maintenance, and implementation of new features have been historically provided by the project coordinator with the help of an advisory committee (1 or 2 members for each research structure) that includes representatives of the four professional set of actors mentioned above. Presently, CRIS-INAF is under revision to reorganize the database structure as well as optimize its interoperability with SAO/NASA ADS and with the institute's administrative databases. The introduction of additional functionalities is being considered. This paper describes some characteristics of the fruitful inter-professional cooperation which has been essential for the functionality and improvements of the system.

    The Centro Nazionale Terremoti (CNT - National Earthquake Center), departement of Istituto Nazionale di Geofisica e Vulcanologia (INGV), has designed and setup a rapid response emergency structure to face the occurrence of strong earthquakes. This structure is composed by a real time satellite telemetered temporary seismic network (see Abruzzese et al., 2009 Fall AGU) used to improve the hypocentral locations of the INGV National Seismic Network, a stand alone temporary seismic network whose goal is primarily the high dynamic/high resolution data acquisition in the epicentral area and a mobile operational center, the COES (Centro Operativo Emergenza Sismica, Seismological Emergency Operational Center). The COES structure is a sort of mobile office equipped with satellite internet communication that can be rapidly installed in the disaster area to support all the INGV staff operative needs and to cooperate with the Civil Protection department (DPC) aggregating all the scientific information available on the seismic sequence and providing updated information to Civil Protection for the decision making stage during the emergency. The structure is equipped with a heavy load trolley that carries a 6x6 inflatable tent, a satellite router, an UPS, computers, monitors and furniture. The facility can be installed in a couple of hours in the epicentral area and provides a full featured office with dedicated internet connection and VPN access to the INGV data management center in Rome. Just after the April 6 2009 Mw 6.3 earthquake in L’Aquila (Central Italy) the COES has been installed upon request of the Italian Civil Protection (DPC) in the DICOMAC (Directorate of Command and Control - which is the central structure of the DPC that coordinates the emergency activities in the areas affected by the earthquake) located in the Guardia di Finanza headquarters in Coppito nearby L'Aquila (the same location that hosted the G8 meeting). The COES produces real time reports on the

    The Laboratorio di Didattica e Divulgazione Scientifica Group of the INGV organizes every year intense educational and outreach activities with schools of different grades. The visit to the scientific laboratories of the INGV center of Rome represents the earliest and the most continuous project started about 10 years ago. During these years the INGV center was visited by more than 20,000 students. The researchers and the technicians of the INGV receive with competence and enthusiasm the students in order to transfer scientific knowledge and enthusiasm for scientific research, science and nature. Since Italy is a place prone to seismic and volcanic activities our lessons focalize in particular on causes of earthquakes and volcanic eruptions and how to behave properly during these events. This approach derived from the consciousness that preparedness is the best way to live with and to mitigate natural hazards. The visit consists of a theoretical lesson in a conference hall supported by multimedia tools, and a practical experiences based on exhibitions and hands-on experiments focused on earthquakes, plate tectonics and the inner structure of the Earth. A special experience is the visit to the control room of the INGV National Seismic Surveillance where the students can see in real time the seismic activity and how it is important its continuous monitoring 24-hours a day all year round. In the 2007-2008 scholastic year about 50 classes for more than 2,500 students and their teachers interacted with about 40 scientists. For some of the classes the visit gave the start to independent and original work. This is the case of a IVth primary school class that once back to the desk and encouraged by the teachers resumed their impressions and what their better grasped. The result is a "book" realized like a diary from their original drawings with a final section devoted to a research work they have independently done on volcanoes. The kids with a scientifically correct approach produced a tool particularly fruitful for other students due to the common language used. We made these products available to other schools. In fact, we think that in this way students can better appreciate and comprehend subjects sometimes considered "tricky" and "boring".

    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.

  15. 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

    The National Cancer Institute of Bari (Istituto di Ricovero e Cura a Carattere Scientifico, IRCCS) has been involved since the conception of the project of the Italian Ministry for Health aimed to validate the applicability of the Organisation of European Cancer Institutes (OECI) accreditation and designation (A&D) model to the Network of Italian Cancer Centers, IRCCS, of Alleanza Contro il Cancro. The self-assessment phase of the Institute started in September 2013 and ended in June 2014. All documents and tools were transferred to the OECI A&D Board in June 2014 and a 2-day peer review visit was conducted in October 2014 by an international qualified audit team. The Institute received its final designation and certification in June 2015. The OECI A&D Board, in its final report, came to the conclusion that Istituto Tumori "Giovanni Paolo II" of Bari has a strong research component with some essential elements of comprehensive cancer care still under development; the lack of a system for using outcome data for the strategic management approach to decision-making and missing a regular internal audit system eventually helping further quality improvement were reported as examples of areas with opportunities for improvement. The OECI A&D process represented a great opportunity for the cancer center to benchmark the quality of its performance according to standard parameters in comparison with other international centers and to further develop a participatory group identity. The common goal of accreditation was real and participatory with long-lasting positive effects. We agree with the OECI comments about the next areas of work in which the Institute could produce future further efforts: the use of its powerful IT system as a means for outcome analysis and empowerment projects for its cancer patients.

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.

    Science.gov (United States)

    Jackson, Ralph

    2010-01-01

    Bladder stones, one of the scourges of the past, have been recorded as far back as 6,500 BC. Lithotomy was famously proscribed in the Hippocratic Oath, but it was certainly being undertaken in Hellenistic Alexandria by the 3rd century BC. However, the earliest surviving description of the operation is that of Celsus in the early 1st century AD, while identifiable instrumentation currently dates between the 2nd and early 5th century AD. Finds from Rimini, Marcianopolis, Ephesus and Cyrene illustrate how widespread the operation was at the time of the Roman Empire, but the majority of lithotomy instruments, of which those in the Museo Nazionale Romano are an important part, have been discovered in Rome itself doubtless a reflection of the size of the city's medical 'market'.

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

  8. Acquamanili nella liturgia cristiana (IV-XVI secolo: il bronzo della Pinacoteca Nazionale di Cagliari

    Full Text Available Aquamaniles are tools that have a liturgical function in the Christian rite, the origins of which are likely to be linked to objects of profane use. This essay analyses the function and the types of the few examples that have survived to this day, dating from the eighth to the sixteenth century. These ornaments have a signifi cant position in the specialist historiography, having been considered by art historians to be “among the most artistic objects,” especially those produced in bronze. Bronze is the material used for the aquamanile in the shape of a peacock that is kept in the National Gallery in Cagliari. Subjecting this important object to historiographical and archival analysis, this study advances a formal comparison that suggests a chronological framework and a place of origin based on historical data.[it] Gli acquamanili sono degli utensili che hanno una funzione liturgica nel rito cristiano, le cui origini sono verosimilmente legate a oggetti di uso profano. Il saggio analizza la funzione e le tipologie dei pochi manufatti giunti ai giorni nostri, databili tra l’VIII e il XVI secolo. Queste suppellettili occupano una posizione particolare nella storiografi a specialistica, in quanto considerati dagli studiosi “tra gli oggetti più artistici”, principalmente nell’ambito dei bronzi. Di tale materiale è costituito l’acquamanile a forma di pavone musealizzato nella Pinacoteca Nazionale di Cagliari, per il quale si affronta un’analisi storiografica e d’archivio, si propongono dei confronti formali e si suggeriscono un inquadramento cronologico e un ambito di provenienza basato sui dati storici.

    Full Text Available L’articolo intende esaminare le caratteristiche principali dell’«italiano musicale» in alcune partiture del repertorio vocale classico giapponese del XIX e del XX secolo. Nella parte introduttiva vengono esaminati i tratti principali della storia e della cultura musicale giapponese, con particolare riferimento all’introduzione del sistema occidentale e alla sua fusione con il repertorio preesistente durante l’epoca Meiji; vengono successivamente presentati in traduzione alcuni brani particolarmente rappresentativi, con alcune indicazioni biografiche sui rispettivi autori.Nella seconda parte, viene esaminato più nel dettaglio il lessico musicale in alcune partiture, seguendo la seguente classificazione: 1 indicazioni sul genere e sul titolo delle composizioni; 2 indicazioni di carattere agogico e di espressione; 3 indicazione di carattere dinamico. Particolare attenzione è dedicata alle motivazioni che spingono i compositori giapponesi ad alternare la lingua italiana alla lingua nazionale, nonché alla capacità dell’«italiano musicale» di adattarsi alle peculiari esigenze espressive di un orizzonte artistico piuttosto lontano da quello europeo. Italian and Japanese language in some japanese music scoresThe article will examine the main features of Italian musical language in some scores of the Japanese classical vocal repertoire of the nineteenth and twentieth centuries. The introductory part reviews the main features of the history and culture of Japanese music, particularly in the context of the Western system and its merging with the existing repertoire during the Meiji era; some particularly significant translated excerpts are presented, with some biographical information about the authors.In the second part, the musical lexicon in some scores is examined in greater depth, classified in the following manner: 1 details of the type and title of the compositions; 2 agogic and expressive aspects; 3 indication of the dynamics

    2015-01-01

    Faced with the challenge of ensuring high-quality and cost-effective health systems in the context of persistent financial crisis, a global strategy for cancer prevention and treatment represents a priority for public health bodies and governments. The key goals for the initiative are to define standards of cancer prevention and care while leveraging the continuous progress of biomedical research in the interest of public health. In Italy, the establishment of a network of Comprehensive Cancer Centres (CCC) named the Alliance Against Cancer (ACC) is an important initiative taken by the Ministry of Health to foster common strategies for enhancing the quality of oncology research and care at the national level. The Istituto Superiore di Sanità (ISS) has played an important role in supporting ACC activities through a special national program called ISS for ACC, launched by the Italian Ministry of Health in 2006. A similar role has been pursued in subsequent initiatives, including ISS support for a project aimed at providing international accreditation of the CCC of the ACC, funded by the Italian Ministry of Health. The results of this initiative, reported in the current issue of Tumori, are especially significant since specific indicators of quality for research and cancer care have been successfully defined for all the participating institutes. As the leading technical and scientific body of the Italian National Health Service, the ISS will continue to play a proactive role in supporting national networks and strategic national and international initiatives aimed at promoting public health.

    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.

    2003-10-01

    Full Text Available Durante il periodo riproduttivo del 2000, 2001 e 2002, sono state effettuate delle osservazioni comportamentali su un campione (n=42 di maschi di stambecco (Capra ibex ibex riconoscibili individualmente, all?interno del Parco Nazionale del Gran Paradiso. Le osservazioni di ciascun maschio sono state distribuite uniformemente nel corso del periodo riproduttivo. In totale sono state effettuate 111 ore di osservazione nel 2000, 120 ore nel 2001 e 95 ore nel 2002. Sono state analizzate le diverse strategie riproduttive utilizzate e confrontati gli anni di studio. Marcate differenze individuali sono state rilevate nelle percentuali di tempo trascorso in corteggiamento ed in interazione aggressiva con altri maschi. Infatti, gli individui che trascorrono molto tempo in corteggiamento (media percentuale 25,6%, passano poco tempo ad interagire con altri maschi (media percentuale 1,1% e viceversa, maschi che trascorrono molto tempo in interazioni aggressive con altri maschi (media percentuale 14,8%, passano poco tempo in corteggiamento (media percentuale 2,4%. Gli spostamenti verso le femmine ed il numero di femmine corteggiate sono molto influenzati dalle condizioni ambientali. Infatti, con un?elevata presenza di neve al suolo, come nel caso del periodo riproduttivo 2000, i movimenti degli animali sono fortemente limitati ed i maschi trascorrono meno tempo in spostamenti da gruppi diversi di femmine e ne corteggiano quindi un numero minore. Nel corso degli anni sono state evidenziate differenze anche nelle diverse strategie riproduttive adottate: in assenza di neve, i maschi utilizzano sia i corteggiamenti statici (percentuale media 17,2%, effettuati dai maschi adulti per lungo tempo, che i corteggiamenti dinamici (percentuale media 1,0%, osservati nei maschi giovani in corsa. Al contrario, con un?elevata copertura nevosa (periodo riproduttivo 2000, non sono stati osservati corteggiamenti dinamici ed è aumentata la percentuale media del tempo

    Full Text Available Il presente contributo si sofferma sulle condizioni dell’insegnamento dell’italiano alle elementari di una scuola tedesca di Milano, l’Istituto Giulia, a cavallo degli anni Trenta del Novecento. La presenza di un’elevata ed eccezionale percentuale di italofoni accanto ai madrelingua tedeschi creò classi linguisticamente non omogenee, un problema cui si fece fronte con aggiustamenti di orario, reclutamento di maestre prima bilingui poi italiane, e l’elaborazione di un metodo innovativo da parte di Sr. Maria Hildegara Heinz, maestra tedesca in possesso di diploma magistrale sia tedesco sia italiano. Partendo da un approccio positivo al bilinguismo, visto come un fattore di agevolazione dell’apprendimento e non come ostacolo, Sr. Hildegara elaborò per l’apprendimento della lettura e della scrittura un metodo contrastivo e realizzò un’unificazione della didattica che riguardava fonetica, morfologia, lessico e contenuti culturali. Descritto in una relazione che Sr. Hildegara presentò a un convegno nel 1929, il metodo viene qui contestualizzato, confrontato con le scelte didattiche della maestra dell’altra scuola tedesca a Milano, e proposto in traduzione. «Building bridges between languages».  Italian L2 at the “Scuola Germanica Istituto Giulia” in Milan (1925-1935 This paper focuses on the teaching of Italian in the primary classes of a German school in Milan, the Giulia Institute, in the 1930s. The presence of an exceptional proportion of Italian speakers with German native speakers created classes that were not linguistically homogeneous, a problem faced by making time adjustments, the recruitment of bilingual teachers and later Italian ones, and the development of an innovative method by Sister Maria Hildegara Heinz, a German teacher with both German and Italian teaching diplomas. Starting from a positive attitude towards bilingualism, seen as a factor facilitating learning and not as an obstacle, Sister Hildegara

    This Act amended substantially Act No. 1240 of 1971 restructuring the Comitato Nazionale per l'Energia Nucleare - CNEN. 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

    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.

    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.

    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 P<.05. Information on 198 patients was collected. Only 8 patients (4%) died from causes directly associated with bleeding. 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.

Per ogni individuo sono state raccolte almeno 12 localizzazioni mensili dall?estate del 2000 alla primavera del 2002. Sono state calcolate le dimensioni degli home range, annuali e stagionali, con il metodo del minimo poligono convesso (MPC e con il metodo di Kernel. Le dimensioni medie degli home range annuali (MPC: 186.2±71.71ha, 2000; 182.2±70.03ha, 2001; Kernel: 316.3±111.00 ha, 2000; 304.8±101.14ha, 2001 sono sensibilmente inferiori rispetto ai dati presenti in bibliografia; ciò non desta stupore in considerazione del fatto che la popolazione in esame in questa ricerca è l?unica autoctona. Non esiste una correlazione tra le dimensioni degli home range e l?età, mentre l?analisi degli spazi vitali relativi alla stagione estiva indica una differenza tra le femmine accompagnate dal piccolo e quelle sole. Nelle stagioni successive non risulta esserci un differente comportamento spaziale tra le femmine allattanti e quelle non allattanti. La presenza di neve al suolo influenza le dimensioni degli home range invernali: con molta neve gli spostamenti sono ridotti.

    The first contribution deals with chemical contaminants, particularly heavy metals and their acceptable daily intake (ADI). The following contributions deals with sanitary measures concerning biological contamination associated with the consumption of seafood, especially shellfish, taking into consideration the epidemiological relevance of some biological contaminants in Italy and Europe. Particular sanitary aspects concerning the presence of enteric viruses in mussels are presented; new molecular biology methodologies and the different techniques for enteroviruses concentration are discussed. Some questions concerning the detection of algal bio toxins are shown, based on the experience recently acquired by the Istituto Superiore di Sanita` about the biological methods. The current chromatographic methods for PSP and DSP biotoxin determination and the most recent developments in chemical methods based on liquid chromatography and mass spectrometric techniques are presented. The last section is devoted to the parasitic contamination of seafood.

    The plasma chamber is particularly suitable to perform studies for the following applications: - plasma compatibility and functional tests on payloads envisioned to operate in the ionosphere (e.g. sensors onboard satellites, exposed to the external plasma environment); - calibration/testing of plasma diagnostic sensors; - characterization and compatibility tests on components for space applications (e.g. optical elements, harness, satellite paints, photo-voltaic cells, etc.); - experiments on satellite charging in a space plasma environment; - tests on active experiments which use ion, electron or plasma sources (ion thrusters, hollow cathodes, field effect emitters, plasma contactors, etc.); - possible studies relevant to fundamental space plasma physics. The facility consists of a large volume vacuum tank (a cylinder of length 4.5 m and diameter 1.7 m) equipped with a Kaufman type plasma source, operating with Argon gas, capable to generate a plasma beam with parameters (i.e. density and electron temperature) close to the values encountered in the ionosphere at F layer altitudes. The plasma beam (A+ ions and electrons) is accelerated into the chamber at a velocity that reproduces the relative motion between an orbiting satellite and the ionosphere (≈ 8 km/s). This feature, in particular, allows laboratory simulations of the actual compression and depletion phenomena which take place in the ram and wake regions around satellites moving through the ionosphere. The reproduced plasma environment is monitored using Langmuir Probes (LP) and Retarding Potential Analyzers (RPA). These sensors can be automatically moved within the experimental space using a sled mechanism. Such a feature allows the acquisition of the plasma parameters all around the space payload installed into the chamber for testing. The facility is currently in use to test the payloads of CSES satellite (Chinese Seismic Electromagnetic Satellite) devoted to plasma parameters and electric field measurements in a polar orbit at 500 km altitude.

    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.

Samples of water (n=12 and feces (n=59, collected at 10 different sites, were cultured for E. coli and Enterococcus spp. The resulting colonies were screened for tetracycline, ampicillin and kanamycin resistance using the Lederberg Replica Plating method (breakpoint 4 μg/ml. All resistant isolates were then selected, and subjected to the CLSI antimicrobial plate susceptibility test (7. Among the water specimens contaminated by E. coli, 80% were found to be resistant to ampicillin, 80% to tetracycline and 40% to kanamycin. Among the water specimens contaminated by Enterococcus spp., 14.29% were found to be resistant to ampicillin, 14.29% to tetracycline and 71.3% to kanamycin. Among the 39 strains of E. coli isolated from red deer feces, 12 were resistant to ampicillin (30.77%, 5 to tetracycline (12,82% and 3 to kanamycin (7.69%. Among the 19 strains of Enterococcus spp. isolated from red deer feces, 0 were resistant to ampicillin (0%, 1 to tetracycline (5.26% and 19 to kanamycin (100. These are significant findings, indicating that antibiotic resistance can be found in naïve animal populations and that red deer and fallow deer could act as sentinels for antimicrobial resistance.

    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

    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.

    PCDD/F air emission factors (EFs) from municipal solid waste (MSW) incinerators are commonly found in the literature from handful of sources, but widely accepted values of PCDD/F air EFs still lack for Italian MSW incinerators. This is one of the reason why an Italian PCDD/F air emission inventory still lacks too. Seven facilities (located in Regione Lombardia) were chosen in order to produce a first assessment of field-based on literature EFs. This careful assessment allows to obtain a reasonable estimation of total annual PCCD/F air emissions from the 38 Italian MSW incinerators in 1997 (11.5 gI-TEQ y{sup -}1). This value will decrease to 5.6-8.5 gI-TEQ y{sup -}1 even if MSW incinerators will comply with the 0.1 mgI-TEQ Nm{sup -}3 air emission limit value, recently came into force in Italy. Moreover, a sharp reduction of the emission-to-energy ratio from 26.53 to 0.88-1.12 mgI-TEQ GWh{sup -}1 will be expected, due to the mandatory use of energy recovery devices since January 1999. [Italian] Mentre i fattori di emissione (FE) in atmosfera di policlorodibenzo-p-diossine (PCDD) e policlorodibenzofurani (PCDF) da inceneritori di rifiuti urbani (RU) sono abbastanza diffusamente riportati nella letteratura tecnica internazionale, esiste invece ancora una assoluta carenza di dati a livello nazionale. Lo stesso puo' dirsi per gli inventari nazionali di emissioni di PCDD/F in atmosfera. E' questo il motivo per cui sono stati individuati sette inceneritori lombardi, per i quali erano disponibili sufficienti dati su base storica (1991-1997), al fine di effettuare una stima diretta dei FE da applicarsi all'inventario nazionale delle diossine. Sulla base dei FE cosi' calcolati e di altri FE riportati in letteratura si e' potuta determinare una emissione globale annua dai 38 inceneritori di RU (Rifiuti Urbani) operanti in Italia nel 1997 di 11,5 gI-TEQ anno{sup -}1. Tale emissione si potra' ridurre a 5,6-8,5 gI-TEQ anno {sup -}1 nel prossimo

    CERN Document Server

    Sidoti, A; Busetto, G; Castro, A; Dusini, S; Lazzizzera, I; Wyss, J

    2001-01-01

    In this work we present the results of a neural network (NN) approach to the measurement of the tt production cross-section and top mass in the all-hadronic channel, analyzing data collected at the Collider Detector at Fermilab (CDF) experiment. We have used a hardware implementation of a feedforward neural network, TOTEM, the product of a collaboration of INFN (Istituto Nazionale Fisica Nucleare)-IRST (Istituto per la Ricerca Scientifica e Tecnologica)-University of Trento, Italy. Particular attention has been paid to the evaluation of the systematics specifically related to the NN approach. The results are consistent with those obtained at CDF by conventional data selection techniques. (38 refs).

    The European Space Agency’s Planck satellite, launched the 14th of May 2009, is the next-generation space experiment in the field of Cosmic Microwave Background (CMB) research. It will image the anisotropies of the CMB over the whole sky, with unprecedented sensitivity and angular resolution. Planck will provide a major source of information relevant to many fundamental cosmological problems and will test current theories of the early evolution of the universe and the origin of structure. It will also address a wide range of areas of astrophysical research related to the our Galaxy as well as external galaxies and clusters of galaxies. The ability of Planck to measure polarization across a wide frequency range (30-350 GHz), with high precision and accuracy, and over the whole sky, will provide unique insight not only into specific cosmological questions, but also into the properties of the interstellar medium. This paper is part of a larger package which describes the technical capabilities of the Planck sc...

    Full Text Available This article focuses on the refoundation of Socialist International after the Second World War (1945-1951. It tackles three elements of socialist history through the archives preserved at the Institute of Social History in Amsterdam: the socialist building of an International organization, the new ideas and political issues in the socialist political culture, the socialist support to European technical governance. In this way, the paper underlines some crucial points as the relation between socialism and Nation State, and introduces the European integration question.

  20. Conference Held at the Centro Linceo Interdisciplinare, Accademia Nazionale dei Lincei

    CERN Document Server

    1980-01-01

    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...

    Full Text Available In the paper we are explaining those aspects of the Italian Communist Party, that, thanks to the particular organized structure, contributed, in a meaningful way, to outline some characteristic features of the Italian political culture. There are four aspects of them: the first one was represented by a strong level of ideologism that for reaction and contamination passed from its main centre of diffusion (which was just the P.C.I to the other actors of the Italian party system, whose high level of ideologization produced models of interpretation of problems and of decisions, elaboration and planning, about not so much pragmatic plans; on the contrary, concerning rhetoric or propagandistic approaches.A second, relevant effect to which contributed in this case not only the political communist culture, we are analyzing above all from this point of view: it was constituted by the leadership exerced by the political parties that acquired in the symbolic values of the Italians universe as regards the other components of the Political system; the consequences of this situation we are going to analyze in the paper.A third element was the strong statalism which constituted the political culture of the country at least till the end of seventies.The fourth factor spread by the political communist culture was given by the egualitarianism. It assumed a relevant role at the organizing and structural level concerning the burocratic machinery; the values connected to it not always produced good results in efficiency, in resources optimization and productivity.

  2. Inflazione mondiale e politica nazionale di stabilità monetaria. (World inflation and domestic monetary stability

    Full Text Available Since the end of the Second World War the world economy has, apart from brief interludes of price stability, been in the grip of continuous inflation. No country seems to have managed to escape this world inflation entirely, although a few have made the very greatest efforts to do so. The present article considers why these efforts were in vain and if there really is no defence against “imported” world inflation. The author analyses the four types of policy for avoiding inflation - restrictive monetary and fiscal policy, export of capital, periodic changes in exchange parities and flexible exchange rates. The analysis suggests that the first two are least recommendable in the face of chronic balance of payments surpluses because they do not eradicate the surplus itself and can be sustained for only a relatively short period of time. The latter two do eliminate the external surplus, however, in the face of continuous world inflation, periodic  revaluation does so only temporarily while flexible rates represent a permanent solution. The author concludes that world inflation can be checked only if there is an international monetary order which keeps reserves so scarce that no country feels able to allow inflation to proceed.JEL: E31, E42, E52, E62

  4. La leadership politica in Italia alla luce della tradizione comica nazionale

    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.

    TNG is a 4m class active optics telescope at the Observatory of Roque de Los Muchachos. In the framework of keeping optimum performances during observation and continuous reliability the telescope control system (TCS) of the TNG is going through a deep upgrade after nearly 20 years of service. The original glass encoders and bulb lamp heads are substituted with modern steel scale drums and scanning units. The obsolete electronic racks and computers for the control loops are replaced with modern and compact commercial drivers with a net improvement in the motors torque ripple. In order to minimize the impact on the number of nights lost during the mechanical and electronic changes in the TCS the new TCS is developed and tested in parallel to the existing one and three steps will be taken to achieve the full upgrade. We describe here the second step that affected the main axes of the telescope, AZ and EL.

    The Conference was organized to celebrate the 50th anniversary of the cervical smear test, commonly referred to as the `Pap test` after its creator, George Nicholas Papanicolaou. The reports present the development of the test, its worldwide application, and its performance as the screening test for the detection of cervical cancer. Pap smear screening for precursors of carcinoma of the cervix has led to dramatic decrease in the incidence and deaths from this cancer. The test represents one of the greatest achievements in preventive medicine.

    The management of ductal intraepithelial neoplasia (DIN) has substantially changed over the past 30 years, as its incidence has increased (from 2-3% to more than 20%), mainly due to the widespread use of mammography screening. This article describes not only the more widespread theoretical concepts on DIN but also the differences in the practical applications of the theory between different countries, different oncology specialists, and different cancer centers. Papers related to the international multicentre-randomized trials and retrospective studies were analyzed. We include articles and papers published between 1993 and 2010 related to patients with DIN, and abstracts and reports from MEDLINE and other sources were indentified. The standard of care for DIN consists of (a) breast conservative surgery (mastectomy is still indicated in large lesions--masses or microcalcifications--in about 30% of cases); (b) radiotherapy (RT) after conservative surgery, and (c) medical treatment in estrogen receptors-positive patients. However, most studies have shown significant differences between theory and practical application. Moreover, there are differences regarding (a) the indications of sentinel lymph node biopsy, (b) the definition and identification of low-risk DIN subgroups that can avoid RT and tamoxifen, and (c) the research into new alternative drugs in adjuvant medical therapy. A general agreement on the best management of DIN does not exist as yet. New large trials are needed in order to define the best management of DIN patients which is (in most respects) still complex and controversial.

    The growing importance in medical practice of a standardized diagnosis in cyto- and histopathology and the recent recommendations for the adoption of standardized schemes for quality control in anatomic pathology by International Committees stimulated the medical staff of the Institute of Anatomic Pathology of the University of Bologna to adopt a pertinent method. The method used by the Department of Pathology of the Yale University (New Haven, Connecticut, USA) was chosen. A Committee for the quality control was appointed and two kinds of controls were set up: an External Quality Assessment (review of the difficult cases by external experts, slide seminars) and an Internal Quality Assessment performed by the members of the Committee on the diagnostic and laboratory routine of the Institute. Such a survey is periodically monitored during the monthly meetings of the Committee and described in the monthly reports. The present paper illustrates the method adopted and the preliminary results obtained in order to stimulate the discussion of such a critical theme in contemporary Anatomic Pathology at a national level.

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

    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.

    2003-10-01

    Full Text Available In questo contributo si analizza la dieta di quattro specie di Mammiferi valutando le differenze inter e intraspecifiche. Sono state analizzate 110 feci di Volpe (Vulpes vulpes, 75 di Martes sp., 58 di Donnola (Mustela nivalis e 21 di Tasso (Meles meles da febbraio 2001 a dicembre 2002 in aree caratterizzate da differente altitudine e paesaggio: due aree situate nel PNCVD. In ambiente montano la categoria trofica utilizzata con frequenze percentuali maggiori è quella degli Artropodi: 43% per Martes sp., 41% per la Donnola, 38% per la Volpe, mentre la specie che sfrutta in minori quantità questa risorsa è il Tasso (34%. Quindi, la competizione trofica maggiore è risultata per gli Artropodi, in particolare fra Martes sp., Donnola e Volpe e, in misura minore, fra queste ed il Tasso. Di fatto, il Tasso predilige i Vegetali (41%. Può esserci una modesta competizione tra la Volpe e Martes sp. per i Mammiferi di cui si nutrono frequentemente (32% e 30% rispettivamente. Tale situazione non si verifica per Donnola (6% e Tasso (19%. Nell'ambiente fluviale massima sovrapposizione delle nicchie trofiche esiste, invece, per l'utilizzo dei Vegetali, in particolare fra Volpe (40%, Martes sp. (53% e Donnola (53%. Mentre, riguardo all'assunzione di Artropodi, la Volpe (35% si discosta da Martes sp. (25% e dalla Donnola (32% in quanto si nutre di questi animali in maggiori quantità. Condizioni analoghe sono risultate per i Mammiferi in ambiente fluviale. Attraverso un'analisi multivariata di tutti i dati alimentari, si è osservata la notevole separazione della nicchia trofica della Volpe in ambiente vallivo rispetto alle altre specie e soprattutto relativamente ad Artropodi Imenotteri e Ditteri. In ambiente montano la nicchia della Volpe si avvicina a quella di Martes sp. in particolare per la predazione di Uccelli e Ortotteri. Martes sp. è risultata la specie più generalista sia a basse che ad elevate quote. Anche la nicchia trofica della Donnola appare differenziarsi fra area valliva e montana, dove è lievemente sovrapposta a quella del Tasso, soprattutto per gli Insetti. Dall'analisi risulta evidente la tendenza di tutti i Carnivori esaminati ad un maggiore sfruttamento delle risorse vegetali in ambiente vallivo dove sono presenti in grandi quantità grazie sia a temperature più miti, acqua e presenza di campi coltivati. In generale è stata osservata una bassa competizione trofica nei Carnivori di ambienti montani e vallivi, probabilmente in ragione di un'elevata disponibilità delle risorse alimentari presenti sul territorio. Le specie dimostrano una buona adattabilità alimentare ai cambiamenti imposti dal gradiente altitudinale, dalle differenti condizioni climatiche e dalle caratteristiche ecologiche derivanti dalla presenza antropica. Rimangono costanti, comunque alcuni elementi della dieta (artropodi e vegetali che vengono integrati in ognuno dei siti.

    The foundation of C. N. R. in 1923 created in Italy a new public system of research, different from the university one. During fascism, the contribution of C. N. R. to the development of medical research in Italy was very poor. This was mainly due to insufficient means: structures and money. Moreover, the scientists who carried on medical research within the C. N. R. were the same who already held strong university positions, which mean a complete dependence on the academic system. The ideology of fascism also contribute to the weakness of the Italian medical research promoted by the C. N. R.. According to fascist view, science, and for its nature and aims above all medicine, had to addressed to technical, practical, or much better, social achievements. Consequently, the policy of medical research at the C.N.R. was to improve social or political medicine, mainly hygiene. This was in harmony with the demographic policy, which means the policy of reinforcement of "Italian race", and positive eugenics that fascism tried to pursue.

    Full Text Available This article aims to analyze the relations between the trial of Adolf Eichmann and the Israeli national identity. It analyzes a trial which has its roots in the ius gentium and continues until the reappropriation of the memory of the Holocaust by Israel. The trial of Nazi criminal represents the moment when the Jewish state integrates his national experience to the memory of the destruction of European Jewry during the Second World War. Through the trials against Eichmann and its consequences on the Israeli public opinion, Ben Gurion strove for a nationalist rewriting of the Holocaust. The role of justice and law is central to the development of the national identity of Israel, providing a renewed civil identity that makes Israel the ‘guardian’ of memory and shifting the focus from the classic themes of Zionism.

    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

    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.

  18. The many facets of extragalactic radio surveys: towards new scientific challenges

    Science.gov (United States)

    2015-10-01

    Radio continuum surveys are a powerful tool to detect large number of objects over a wide range of redshifts and obtain information on the intensity, polarization and distribution properties of radio sources across the sky. They are essential to answer to fundamental questions of modern astrophysics. Radio astronomy is in the midst of a transformation. Developments in high-speed digital signal processing and broad-band optical fibre links between antennas have enabled significant upgrades of the existing radio facilities (e-MERLIN, JVLA, ATCA-CABB, eEVN, APERTIF), and are leading to next-generation radio telescopes (LOFAR, MWA, ASKAP, MeerKAT). All these efforts will ultimately lead to the realization of the Square Kilometre Array (SKA), which, owing to advances in sensitivity, field-of-view, frequency range and spectral resolution, will yield transformational science in many astrophysical research fields. The purpose of this meeting is to explore new scientific perspectives offered by modern radio surveys, focusing on synergies allowed by multi-frequency, multi-resolution observations. We will bring together researchers working on wide aspects of the physics and evolution of extra-galactic radio sources, from star-forming galaxies to AGNs and clusters of galaxies, including their role as cosmological probes. The organization of this conference has been inspired by the recent celebration of the 50th anniversary of the Northern Cross Radio Telescope in Medicina (BO), whose pioneering B2 and B3 surveys provided a significant contribution to radio astronomical studies for many decades afterwards. The conference was organized by the Istituto di Radioastronomia (INAF), and was held at the CNR Research Area in Bologna, on 20-23 October 2015. This Conference has received support from the following bodies and funding agencies: National Institute for Astrophysics (INAF), ASTRON, RadioNet3 (through the European Union’s Seventh Framework Programme for research

THE BODY BETWEEN PSYCHOANALYSIS, BIOPOLITICS, VIRTUAL REALITY AND ART   The posthuman has become a topic of central interest for the definition of certain key‐elements of Western thought. The May 27, 2016 in Naples an interesting meeting has been held, in which various speakers discussed on the effects that post‐human and posthumanism have been producing in art, philosophy, psychoanalysis and literature. In particular, it was shown that the posthuman is a complex issue that requires multiple strategies to be addressed and understood effectively. The posthuman evokes fears and hopes and in particular it is directly connected with the vocation of man to self‐transcendence, a somehow natural tendency which is leading to a general reorganization of Western man’s identity structures and to a general reshaping of his profound imagery.

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

    From 1975 to 1993, at the Division of Diagnostics and Endoscopic Surgery of the Istituto Nazionale Tumori in Milan, 191 malignant adenomas of colon-rectum have been endoscopically removed. On the basis of histopathologic criteria, endoscopic treatment has been judged adequate in 102 cases (53%), not adequate in 44 (23%), doubtfully adequate in 45 (24%). In 84 patients (44%) endoscopic polypectomy has been followed by surgical resection of the involved intestinal tract, 107 patients (56%) have been treated only by endoscopy. Results have been evaluated on the basis of surgical specimen, clinical follow-up and survival, showing that criteria we have adopted for the adequacy of the endoscopic treatment have a high negative predictive value (96%) and a low positive predictive value (32%). Actuarial survival of patients treated only endoscopically is 97% at 5 years and 95% at 10 years.

    The prototype of the OFFSET (Optical Fiber Folded Scintillating Extended Tracker) tracker is presented. It exploits a novel system for particle tracking, designed to achieve real-time imaging, large detection areas, and a high spatial resolution especially suitable for use in medical diagnostics. The main results regarding the system architecture have been used as a demonstration of the technique which has been patented by the Istituto Nazionale di Fisica Nucleare (INFN). The prototype of this tracker, presented in this paper, has a 20 × 20 cm2 sensitive area, consisting of two crossed ribbons of 500 micron square scintillating fibers. The track position information is extracted in real time in an innovative way, using a reduced number of read-out channels to obtain very large detection area with moderate enough costs and complexity. The performance of the tracker was investigated using beta sources, cosmic rays, and a 62 MeV proton beam.

    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.

    In radiotherapy with carbon ions, biological effects of treatments have to be predicted. For this purpose, one of the most used models is the local effect model (LEM) developed at the Gesellschaft für Schwerionenforschung (GSI), Germany. At the Istituto Nazionale di Fisica Nucleare, Italy, the reliability of the last published version of LEM (LEM III) in reproducing radiobiological data has been checked under both monoenergetic and spread-out Bragg peak (SOBP) carbon-ion irradiation. The reproduction of the monoenergetic measurements with the LEM was rather successful for some cell lines, while it failed for the less-radioresistant ones. The SOBP experimental trend was predicted by the LEM, but a large shift between model curves and measured points was observed.

In the framework of the research on the SPES target, seven uranium carbide discs, obtained by reacting uranium oxide with graphite and carbon nanotubes, were irradiated with protons at the Holifield Radioactive Ion Beam Facility (HRIBF) of Oak Ridge National Laboratory (ORNL). In the following, the yields of several fission products obtained during the experiment are presented and discussed. The experimental results are then compared to those obtained using a standard uranium carbide target. The reported data highlights the capability of the new type of SPES target to produce and release isotopes of interest for the nuclear physics community.

Recently it has been suggested to translate the acquired knowledge in this field towards a Thomson Backscattering Source (TBS), which is presently under development at the Frascati National Laboratories of INFN (Istituto Nazionale di Fisica Nucleare) in Rome, Italy. Such source is capable of producing intense and quasi-monochromatic hard X-ray beams. For the technical implementation of biomedical phase imaging at the TBS a grating interferometer for differential phase contrast imaging has been designed and successfully tested at SYRMEP beamline.

    2013-05-01

    A new methodology and an instrumental setup for the thermal conductivity estimation of isotropic bulk graphite and different carbides at high temperatures are presented. The method proposed in this work is based on the direct measurement of temperature and emissivity on the top surface of a sample disc of known dimensions. Temperatures measured under steady-state thermal equilibrium are then used to estimate the thermal conductivity of the sample by making use of the inverse parameter estimation technique. Thermal conductivity values obtained in this way are then compared to the material data sheets and values found in literature. The reported work has been developed within the Research and Development framework of the SPES (Selective Production of Exotic Species) project at INFN-LNL (Istituto Nazionale di Fisica Nucleare - Laboratori Nazionali di Legnaro).

    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.

    This work presents and describes a 20-year long database of GPS data collected by geodetic surveys over the seismically and volcanically active eastern Sicily, for a total of more than 6300 measurements. Raw data were initially collected from the various archives at the Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Catania—Osservatorio Etneo and organized in a single repository. Here, quality and completeness checks were performed, while all necessary supplementary information were searched, collected, validated and organized together with the relevant data. Once all data and information collections were completed, raw binary data were converted into the universal ASCII RINEX format; all data are provided in this format with the necessary information for precise processing. In order to make the data archive readily consultable, we developed software allowing the user to easily search and obtain the needed data by simple alphanumeric and geographic queries.

    Full Text Available An Advanced Ionospheric Sounder, built at the Istituto Nazionale di Geofisica e Vulcanologia, Rome, Italy, was installed at Tucumán, Argentina, particularly interesting for its location, near the southern peak of the ionospheric equatorial anomaly. The aim of this installation is to collect a large number of continuous data useful both to study the dynamics of the equatorial ionospheric plasma and to develop reliable regional ionospheric prediction models. Moreover this ionosonde will contribute to the ionospheric database and real time knowledge of Southern Hemisphere ionospheric conditions for space weather applications. The ionosonde is completely programmable and two PCs support the data acquisition, control, storage and on-line processing. In this work the first results, in terms of ionograms and autoscaled characteristics, are presented and briefly discussed.

    High-precision measurement of half-life and Qα value of neutral and highly charged α emitters is a major subject of investigation currently. In this framework, we recently pushed half-life measurements of neutral emitters to a precision of a few per mil. This result was achieved by using different techniques and apparatuses at Istituto Nazionale di Fisica Nucleare Laboratori Nazionali del Sud (INFN-LNS) and GSI Darmstadt. Here we report on 213Fr half-life determination [T1/2(213Fr) = 34.14±0.06 s] at INFN-LNS, detailing the measurement protocol used. Direct comparison with the accepted value in the literature shows a discrepancy of more than three sigma. We propose this new value as a reference, discussing previous experiments.

    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.

    A Workshop organised by the CERN Accelerator School, the European Committee for Future Accelerators and the Istituto Nazionale di Fisica Nucleare was held at the Frascati laboratory of INFN during the last week of September 1984. Its purpose was to bring together an inter-disciplinary group of physicists to review ideas for the acceleration of particles to energies beyond those attainable in machines whose construction is underway, or is currently contemplated. These proceedings contain some of the material presented and discussed at the Workshop, comprising papers on topics such as: the free-electron-laser, the lasertron, wakefield accelerators, the laser excitation of droplet arrays, a switched-power linac, plasma beat-wave accelerators and the choice of basic parameters for linear colliders intended for the TeV energy region.

    Full Text Available The geological information collected in the last years by the Istituto Nazionale di Geofisica for the city of Rome is used to construct 1- and 2-D models of the nearsurface structure. These models are the basis for the numerical generation of synthetic accelerograms which can simulate the horizontal ground motion (SH waves produced in the different areas of the city by a large (M ? 7 potential earthquake 100 km away in Central Apennines. The proposed methodology yields earthquake engineering parameters (peak ground acceleration and velocity, Arias intensity, energy flux, response spectra whose spatial variations are consistent with the damage distribution caused by the strongest earthquakes felt in Rome during its long history. Based on the macroseismic inforination and the results of the numerical simulations, general criteria for seismic zonation of the city of Rome are proposed.

    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.

    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.

    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.

    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.

    Nuclear magnetic resonance is a powerful technique that can be used in a wide range of applications, such as the structural characterization of high molecular weight molecules, conformational studies on enzymes in solution, enzyme-substrate or DNA-protein interactions, monitoring of cell metabolism in vivo, and for diagnostic purposes, employing spectroscopic and imaging techniques. This course was organized in order to introduce the participants to the fundamentals of NMR spectroscopy, and offer practical advice on performing NMR experiments on cell systems, cell and tissue extracts and animal models. The main implications regarding human experiments were also discussed. Finally the quantification of information and the interpretation of data were considered with regard to the main nuclei observed. [Italiano] La risonanza magnetica nucleare e` una delle tecniche spettroscopiche che meglio risponde all`ampio spettro di condizioni imposto dalla ricerca in biofisica e biomedicina. Il campo applicativo di questa tecnica copre un intervallo molto ampio che va dalla caratterizzazione di strutture di macromolecole con elevato peso moleculare, a studi di tipo conformazionale su enzimi in soluzione e sull`interazione enzima-substrato o DNA-proteine, fino al monitoraggio in vivo del metabolosmi cellulare e alla diagnostica medica con spettroscopia ed imaging. Il corso e` stato articolato in modo da presentare ai partecipanti nozioni di base della spettroscopia RMN, aspetti pratici della realizzazione di esperimenti di spettroscopia in sistemi cellulari, in estratti cellulari e tissutali e in animali da esperimento, nonche` le principali considerazioni relative agli esperimenti nell`uomo. Sono state affrontate tematiche relative alla quantificazione dell`informazione e all`interpretazione dei dati in relazione ai principali nuclei osservati.

    The environment provides both a source of goods and services and a `sink` for residues of the production and consumption processes. This is not reflected into conventional estimate of GDP (gross domestic product), the most commonly used measure of aggregate income. The purpose of this paper is to explore whether environmentally-adjusted national income measure can be derived. In the first part, the authors discuss both the shortcomings of the current national income measures, with reference to environmental and natural resources, and the debate on this issues; then they analyse the existing experiences to provide environmentally-adjusted indicators of national accounts. In the second part, the authors present an evaluation of the costs of environmental degradation in Italy in the period 1988-1990, based on the methodologies adopted in a pilot study carried out by UNSO (United Nations Statistical Office) and the World Bank for Mexico.

    ABSTRACT: At a supranational level, there has been a progressive evolution of the concept of family, which would not seem rooted solely on the traditional concept that refers to heterosexual marriage, nor necessarily requiring the difference in sex of the engaged couple. In Italy, the difficulties encountered in terms of legislative action at a national level, in the purpose of the definition of a legal status to the unions between persons of the same sex, have led, in recent years, many couples to turn to the European Court of Human Rights in order to obtain the recognition, within the italian legal system, of the right to marry for homosexual unions, and the right to the transcript of the marriage or registered partnership concluded abroad. This has generated a lively and stimulating legal and jurisprudential debate. The article aims to reconstruct conceptually the problem raised by the question of "egalitarian marriage", accessible to all couples, regardless of possible gender identity of the contractors, and the resulting answers and solutions offered, in a internal and supranational level, by political and judicial bodies.

    Full Text Available In the last thirty years, women’s history and gender studies have analyzed the 19th century and the Risorgimento, emphasizing women’s role in the public arena thus making the Risorgimento period more complex and articulated to our eyes. Women have covered several different roles: in fact there were militant women organizing and serving on committees, financing military projects, fighting in the battlefields; there were also women who offered their support to exiled or imprisoned patriots and women who have preferred to write in order to motivate men and prepare for action. Maybe because of a sense of shame and reserve, these women have often kept their adventurous and rebellious life in a closet. For this reason their letters, which we are presenting a selected choice of, are particularly precious: they allow us to better understand political ideas and convictions and to uncover some of the contributions they made toward the process of nation building and ultimately unification.

    The Istituto Nazionale di Geofisica e Vulcanologia leads an international project funded by the Italian National Program for Antarctic Research, called Demonstrator of Global Navigation Satellite System (GNSS) Research and Application for Polar Environment (DemoGRAPE), in partnership with Politecnico di Torino, Istituto Superiore Mario Boella, and with South African National Space Agency and the Brazilian National Institute of Space Physics, as key collaborators. DemoGRAPE is a new prototype of support for the satellite navigation in Antarctica. Besides the scientific interest, the accuracy of satellite navigation in Antarctica is of paramount importance since there is always the danger that people and vehicles can fall into a crevasse during a snowstorm, when visibility is limited and travel is restricted to following specified routes using satellite navigation systems. The variability of ionospheric delay and ionospheric scintillation are two of the primary factors which affect the accuracy of satellite navigation. The project will provide a demonstrator of cutting edge technology for the empirical assessment of the ionospheric delay and ionospheric scintillations in the polar regions. The scope of the project includes new equipment for the recording and dissemination of GNSS data and products installed at the South African and Brazilian bases in Antarctica. The new equipment will facilitate the exchange of software and derived products via the Cloud computing technology infrastructure. The project portal is accessible at www.demogrape.net. We report the first Global Navigation Satellite System (GNSS) signal scintillations observed in Antarctica.

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

INGV runs the Italian National Seismic Network (Rete Sismica Nazionale, RSN and other networks at national scale for monitoring earthquakes and tsunami as a part of the National Civil Protection System coordinated by the Italian Department of Civil Protection (Dipartimento di Protezione Civile, DPC. RSN is composed of about 400 stations, mainly broadband, installed in the Country and in the surrounding regions; about 110 stations feature also co-located strong motion instruments, and about 180 have GPS receivers and belong to the National GPS network (Rete Integrata Nazionale GPS, RING. The data acquisition system was designed to accomplish, in near-real-time, automatic earthquake detection, hypocenter and magnitude determination, moment tensors, shake maps and other products of interest for DPC. Database archiving of all parametric results are closely linked to the existing procedures of the INGV seismic monitoring environment and surveillance procedures. INGV is one of the primary nodes of ORFEUS (Observatories & Research Facilities for European Seismology EIDA (European Integrated Data Archive for the archiving and distribution of continuous, quality checked seismic data. The strong motion network data are archived and distributed both in EIDA and in event based archives; GPS data, from the RING network are also archived, analyzed and distributed at INGV. Overall, the Italian earthquake surveillance service provides, in quasi real-time, hypocenter parameters to the DPC. These are then revised routinely by the analysts of the Italian Seismic Bulletin (Bollettino Sismico Italiano, BSI. The results are published on the web, these are available to both the scientific community and the general public.

    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.

    NICS (the Near Infrared Camera Spectrometer) is a cooled near-infrared camera-spectrometer that has been developed in the late 90's at the INAF-Arcetri Astrophysical Observatory for the Ø3.5 m "Telescopio Nazionale Galileo" (TNG) at the La Palma Observatory. The instrument has been operating for regular scientific observations since the beginning of 2001. During the 2001-2007 period it has been used in about 410 nights yielding data which contributed to the production of 60 refereed papers which collected a total of more than 800 citations. At the age of 8 years, NICS is still among the most efficient and versatile infrared instruments existing worldwide. To improve its observational efficiency, we have designed and we are currently developing new control software and GUI interfaces. The former has been devised to optimize the low level tasks (in particular the motors controls), the latter to simplify the communications between the observer and the instrument. We give here a short description of NICS software upgrade.

    To report the technique of 3D-conformal radiation therapy (3D-CRT) currently used at our Institute for the treatment of prostate cancer with a curative intent. A critical review of the technical aspects of the technique is provided. Between December 1995 and October 2000, 334 patients with biopsy-proven adenocarcinoma of the prostate were treated with 3D-CRT. All patients were treated in a prone position with 15 MV X-ray beams and a 6-field technique for all but 20 patients, who were treated with a 3-field technique. Patients were simulated with the rectum and bladder empty. To ensure reproducible positioning, custom-made polyurethane foam or thermoplastic casts were produced for each patient. Subsequently, consecutive CT scan slices were obtained. The clinical target volume and critical organs (rectum and bladder) were identified on each CT slice. The beam's eye view technique was used to spatially display these structures, and the treatment portals were manually shaped based on the images obtained. The beam apertures were initially realized by conventional Cerrobend blocks (48 patients), which were replaced in October 1997 by a computer-driven multi-leaf collimator. The total target dose prescribed at the ICRU point is 76 Gy, delivered in 38 fractions and 54 days. The seminal vesicles are excluded at 70 Gy. Dose-volume histograms were obtained for all patients. If more than 30% of the bladder and/or more than 20% of the rectum receive >95% of the prescribed total dose, the treatment plan is judged as unsatisfactory and is adjusted. The dose-volume histogram can be improved by changing the beam's arrangement and/or weights or by introducing or modifying the wedge filters. 3D-CRT in prostate cancer patients is a highly sophisticated and time-consuming method of dose delivery. Important technical issues remain to be clarified.

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.

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.

    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

    To memorialize the anniversary of the 1976 Friuli earthquake, the Istituto Statale di Istruzione Superiore "Magrini Marchetti" in Gemona del Friuli (NE Italy), with the collaboration of the Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS), has promoted the PRESS40 Project (Prevenzione Sismica nella Scuola a 40 anni dal terremoto del Friuli, that in English sounds like "Seismic Prevention at School 40 years later the Friuli earthquake"). The project has developed in the 2015-2016 school year, starting from the 40th anniversary of the Friuli earthquake, and it aims to disseminate historical memory, seismic culture and awareness of seismic safety in the young generations, too often unconscious of past experiences, as recent seismic hazard perception tests have demonstrated. The basic idea of the PRESS40 Project is to involve the students in experimental activities to be active part of the seismic mitigation process. The Project is divided into two main parts, the first one in which students learn-receive knowledge from researchers, and the second one in which they teach-bring knowledge to younger students. In the first part of the project, 75 students of the "Magrini Marchetti" school acquired new geophysical data, covering the 23 municipalities from which they come from. These municipalities represent a wide area affected by the 1976 Friuli earthquake. In each locality a significant site was examined, represented by a school area. At least, 127 measurements of ambient noise have been acquired. Data processing and interpretation of all the results are still going on, under the supervision of OGS researchers.The second part of the project is planned for the early spring, when the students will present the results of geophysical survey to the younger ones of the monitored schools and to the citizens in occasion of events to commemorate the 40th anniversary of the Friuli earthquake.

    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.

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

    Between 1993 and 1996 the European Union supported the development of a Quality Assurance programme of Information in Marine Environmental Monitoring in Europe (QUASIMEME). The aim of the programme was to improve and control the quality of marine environmental information through inter-laboratory studies on nutrients in sea water, chloro biphenyls and trace metals in sediments and biological tissue. This paper describes the participation of ENEA laboratory (AMB/TEIN/CHIM) to QUASIMEME-Programme for trace metals in sediments and biological tissues.

    Sharing and comparing health data at the international level is made difficult by heterogeneity in real world databases. Our primary objective was to field-test the implementation of the first common database developed conjointly by different national cardiological societies. Based upon G8-Cardio feasibility projects, the Italian Society of Hospital Cardiologists and the French Society of Cardiology joined together to standardize a cardiological, patient-oriented database, created by means of consensus agreement for sharing data in a common server. Quantification of standardization was obtained by analysing each dataset according to the possibility of merging corresponding fields. Data merging from national centres was completed in the common server and after proper data integration in the common database; a comparison was performed between French and Italian populations. Standardization of contents allowed for 89% overall interoperability (merged fields) to be achieved with only 11% divergent fields. All (100%) merged homogeneous data on the first 2717 patients from peripheral centres were selected consecutively from the common database and analysed successfully. Relevant differences between the two populations were outlined. The international standardization and sharing/merging of databases is feasible. This model opens the way to important applications in internationally shared health care policies.

    Full Text Available Issues about the protection, enhancement, promotion of environmental resources have been for a long time the basis of a method of approach to a 'form' of territorial project based on strategies for local development focused on fruition of tourist in historical, cultural, heritage places and landscape. But if on the one hand tourism is a possible device to revitalize local economies in crisis, at the same time in many cases it tends to accentuate the degradation and the loss of identity of these places during the last years. Arises, therefore, the need to reverse this process and to overcome the idea of cultural heritage and landscape conceived as a commodity, and reaffirm the right to the city territories-landscapes to be areas of social life. You need to identify new design procedures able to impact on local systems and at the same time to enter into relationships with global networks, transforming specific values in local values recognizable and globally recognized using local significances to express global meanings.

    TEPHRA is a two dimensional advection-diffusion model implemented by Bonadonna et al. [2005] that describes the sedimentation process of particles from volcanic plumes. The model is used by INGV - Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Catania, to forecast tephra dispersion during Etna volcanic events. Every day weather forecast provided by the Italian Air Force Meteorological Office in Rome and by the hydrometeorological service of ARPA in Emilia Romagna are processed by TEPHRA model with other volcanological parameters to simulate two different eruptive scenarios of Mt. Etna (corresponding to 1998 and 2002-03 Etna eruptions). The model outputs are plotted on maps and transferred to Civil Protection which takes the trouble to give public warnings and plan mitigation measures. The TEPHRA model is implemented in ANSI-C code using MPI commands to maximize parallel computation. Actually the model runs on an INGV Beowulf cluster. In order to provide better performances we worked on porting it to PI2S2 sicilian grid infrastructure inside the "PI2S2 Project" (2006-2008). We configured the application to run on grid, using Glite middleware, analyzed the obtained performances and comparing them with ones obtained on the local cluster. As TEPHRA needs to be run in a short time in order to transfer fastly the dispersion maps to Civil Protection, we also worked to minimize and stabilize grid job-scheduling time by using customized high-priority queues called Emergency Queue.

    In Italy, after the 2009 L'Aquila earthquake, a procedure was developed for gathering and disseminating authoritative information about the time dependence of seismic hazard to help communities prepare for a potentially destructive earthquake. The most striking time dependency of the earthquake occurrence process is the time clustering, which is particularly pronounced in time windows of days and weeks. The Operational Earthquake Forecasting (OEF) system that is developed at the Seismic Hazard Center (Centro di Pericolosità Sismica, CPS) of the Istituto Nazionale di Geofisica e Vulcanologia (INGV) is the authoritative source of seismic hazard information for Italian Civil Protection. The philosophy of the system rests on a few basic concepts: transparency, reproducibility, and testability. In particular, the transparent, reproducible, and testable earthquake forecasting system developed at CPS is based on ensemble modeling and on a rigorous testing phase. Such phase is carried out according to the guidance proposed by the Collaboratory for the Study of Earthquake Predictability (CSEP, international infrastructure aimed at evaluating quantitatively earthquake prediction and forecast models through purely prospective and reproducible experiments). In the OEF system, the two most popular short-term models were used: the Epidemic-Type Aftershock Sequences (ETAS) and the Short-Term Earthquake Probabilities (STEP). Here, we report the results from OEF's 24hour earthquake forecasting during the main phases of the 2016-2017 sequence occurred in Central Apennines (Italy).

    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.

    Volatile organic compounds (VOCs) in gas mixtures at trace level (nmol/mol) are routinely measured by chemical and biochemical laboratories as climate indicators, indoor air quality pollutants from building materials emissions, contaminants in food and beverages, and biomarkers in body fluids (blood, urine, breath) of occupational exposure or human diseases. Current analytical instruments used for measurements are gas chromatographs equipped with various injector and detector configurations. The assurance of measurement quality is done by using a huge amount of certified liquid VOC standard solutions (or gaseous VOC standard cylinders) with multiple dilutions to reach the required trace level. This causes high standard uncertainty in instrument calibrations, high cost, and high consumption of analysis and laboratory personal time. In this paper, we present the implementation of portable generators producing VOC gas standards at trace level for automatic and direct calibration of VOC detectors employed in various contexts, removing the need for preparation of matrix calibration standards in cylinders. Two compact devices in-house developed by two national metrology institutes-the Istituto Nazionale di Ricerca Metrologica (INRIM) and the Federal Institute of Metrology (METAS)-are here used to dynamically generate reference gas mixtures in an SI traceable way. The two devices are based on different technologies: diffusion and permeation, for INRIM and METAS, respectively. A metrological characterization is given and the practical implementation at chemical and biochemical laboratories is discussed.

    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).

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 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.

    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.

    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.

    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 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.

A sociological survey of local residents and employees who work in the building on their perceptions of the green facade is also under development. This monitoring includes surveys before and after the installation of the facade to evaluate if the introduction of foreign elements has destabilizing effects in the context of the domestic environment. This article discusses the results of the survey done before the implementation of the green facade. Other surveys will be carried out in subsequent months in order to understand if the experience of prolonged contact with this new “presence” has changed citizens' perception.

    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.

    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...

    An upgrade to the 2nd generation of the selective production of exotic species (SPES) to produce a radioactive ion beam (RIB) has been studied at the istituto nazionale di fisica nucleare — laboratory nazionali di Legnaro (INFN-LNL). Due to the long distance between the isotope separator online (ISOL) facility and the superconducting quarter wave resonator (QWR) cavity acceleratore lineare per ioni (ALPI), a new re-buncher cavity must be introduced to maintain the high beam quality during the beam transport. A particular radio frequency quadrupole (RFQ) structure has been suggested to meet the requirements of this project. A window-type RFQ, which has a high mode separation, less power dissipation and compact size compared to the conventional normal 4-vane RFQ, has been introduced. The RF design has been studied considering the requirements of the re-bunching machine for high figures of merit such as a proper operation frequency, a high shunt impedance, a high quality factor, a low power dissipation, etc. A sensitivity analysis of the fabrication and the misalignment error has been conducted. A micro-movement slug tuner has been introduced to compensate for the frequency variations that may occur due to the beam loading, the thermal instability, the microphonic effect, etc.

    The 12 GeV upgrade at Jefferson Lab (JLAB) makes many exciting nuclear experiments possible. These experiments also require new high performance instrumentation. The Super Bigbite Spectrometer (SBS) was proposed to perform a series of high precision nucleon form factor experiments at large momentum transfer. The SBS will be capable of operating at a very high luminosity and provide a large solid angle acceptance of 76 msr. SBS will be equipped with a double focal plane polarimeter. Thus, SBS will have three large trackers made of Gas Electron Multiplier (GEM) chambers. The first, second, and third trackers will consist of six, four, and four tracking layers respectively. When completed in 2017, the SBS GEM trackers will form one of the largest sets of GEM chambers in the world. The GEM trackers allow the SBS to operate under high background rates over 500 kHz/cm^2, while providing an excellent spatial resolution of 70 μm. The first tracker will be constructed at the Istituto Nazionale di Fisica Nucleare in Italy, while the second and third trackers will be built at the University of Virginia. In 2012, the first UVa SBS GEM chamber prototype was successfully constructed and tested. The GEM chamber construction details and test results will be presented in this talk.

    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.

    SPES (Selective Production of Exotic Species) is an Isotope Separation On-Line (ISOL) based accelerator facility that will be built in the Legnaro-Istituto Nazionale di Fisica Nucleare (INFN) Laboratory (Italy), intended to provide intense neutron-rich radioactive ion beams obtained by proton-induced fission of a uranium carbide (UCx) target. Besides this main target material, silicon carbide (SiC) will be the first to be used to deliver p-rich beams. This target will also validate the functionality of the SPES facility with aluminum beam as result of impinging SiC target with proton beam. In the past, off line studies on laser photoionization of aluminum have been performed in Pavia Spectroscopy Laboratory and in Laboratori Nazionali di Legnaro; a XeCl excimer laser was installed in order to test the laser ionization in the SPES hot cavity. With the new Wien filter installed a better characterization of the ionization process in terms of efficiency was performed and results are discussed.

    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.

    In this paper we consider the inverse problem of determining, within an elastic isotropic thick plate modelled by the Reissner–Mindlin theory, the possible presence of an inclusion made of a different elastic material. Under some a priori assumptions on the inclusion, we deduce constructive upper and lower estimates of the area of the inclusion in terms of a scalar quantity related to the work developed in deforming the plate by applying simultaneously a couple field and a transverse force field at the boundary of the plate. The approach allows us to consider plates with a boundary of Lipschitz class. The first author is supported by PRIN 2015TTJN95 ‘Identification and monitoring of complex structural systems’.

    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.

    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.

    High precision astrometry requires an accurate geometric-distortion solution. In this work, we present an average correction for the blue camera of the Large Binocular Telescope which enables a relative astrometric precision of ~15 mas for the BBessel and VBessel broad-band filters. The result of this effort is used in two companion papers: the first to measure the absolute proper motion of the open cluster M 67 with respect to the background galaxies; the second to decontaminate the color-magnitude of M 67 from field objects, enabling the study of the end of its white dwarf cooling sequence. Many other applications might find this distortion correction useful. Based on data acquired using the Large Binocular Telescope (LBT) at Mt.

    Under perturbed conditions coming from the outer space, the ionosphere may become highly turbulent and small scale (from centimeters to meters) irregularities, typically enhancements or depletions of the electron density embedded in the ambient ionosphere, can form causing diffraction effects on the satellites signals passing through them. Such effect can abruptly corrupt the performance of the positioning systems affecting, in turn, the awareness and safety of the modern devices. In this paper we analyze data of ionospheric scintillation in the latitudinal range 57°- 88° N during the period October, November and December 2003 as a first step to develop a "scintillation climatology" over the Northern Europe. The behavior of the scintillation occurrence as function of the magnetic local time and of the corrected magnetic latitude is investigated to characterize the scintillation conditions. The Istituto Nazionale di Geofisica e Vulcanologia (INGV) and the Institute of Engineering Surveying and Space Geodesy (IESSG) of the University of Nottingham manage the same kind of GISTM (GPS Ionospheric Scintillation and TEC monitor) receivers over the European middle and high latitude regions. The results here shown and obtained merging observations from three GISTM, highlight also the possibility to investigate the dynamics of irregularities causing scintillation by combining the information coming from auroral to cusp latitudes. The findings, even if at a very preliminary stage, are here presented also in the frame of possible Space Weather implications.

    2006-06-01

    Full Text Available In this work we analyze earthquake parameters published in the Seismic Bulletin of the Istituto Nazionale di Geofisica e Vulcanologia (INGV The analysis and the interpretation of the digital signals, done by specialized employees daily, produce most of the seismological information that comprises INGV’s earthquake bulletins. After a brief introduction on the criteria we use to obtain seismic parameters, this paper will review the processing procedures employed over a period of sixteen years from 1988 to September 2003. This study also addresses the issue of the comparison between Magnitude calculated on signal duration (Md and on amplitude (ML and the lack of a correct calibration between them . A completeness analysis of the whole bulletin performed using both the Stepp and the Habermann techniques shows the importance of considering changes in the seismicity rate and in the geometry of the seismological network. To conclude this excursus, we calculated the errors of hypocentral locations and the detection capacity of individual seismic stations. This final step stresses the increasing improvement of the INGV seismic network over the past 16 years.

  7. Minimum 1D velocity models in Central and Southern Italy: a contribution to better constrain hypocentral determinations

    1997-06-01

    Full Text Available We computed one-dimensional ( I D velocity models and station corrections for Centrai and Southern Italy, in- verting re-picked P-wave alTival times recorded by the Istituto Nazionale di Geofisica seismic network. The re-picked data yield resolved P-wave velocity results and proved to be more suited than bulletin data for de- tailed tomographic studies. Using the improved velocity models, we relocated the most significant earthquakes which occurt.ed in the Apennines in the past 7 years, achieving constrained hypocentral determinations for events within most of the Apenninic belt. The interpretation of the obtained lD velocity models allows us to infer interesting features on the deep structure of the Apennines. Smooth velocity gradients with depth and low P-wave velocities are ob,'ierved beneath the Apennines. We believe that our results are effective to constrain hypocentral locations in Italy and may represent a first step towards more detailed seismotectonic analyses.

    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.

    Previous studies indicate that a multidisciplinary approach could be suitable for dealing with the complex issues faced by physicians in the management of prostate cancer; however, few studies have investigated clinicians' perceptions of multidisciplinary care. Our aim was to evaluate clinicians' perceptions of the patient-clinician relationship in a multidisciplinary context, and to compare this with physicians' perceptions of providing care independently. A qualitative observational study was performed in 2009. Three radiation oncologists, three urologists, three medical oncologists and one psychologist from the multidisciplinary clinic (MDC) team at the Prostate Program of Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy, were interviewed to assess their perceptions of their relationship with the patient. Clinicians reported that the MDC has advantages regarding providing patients with more accurate information and acquiring information from patients, but a clear preference for a multidisciplinary setting did not emerge. Clinicians reported that in one-on-one examinations (1) they feel more comfortable listening to the patient and more able to manage communication, and that (2) the process of building trust is easier. Clinicians appear to recognize the value of the MDC in terms of effective communication with patients but feel that other aspects of relationship building are hindered in a multidisciplinary setting. Organizational and teamwork issues need to be addressed to optimize the implementation of a multidisciplinary approach.

    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
    Physics activities within IGY. Furthermore, we highlight the importance of this historical event and its outcomes
    for the improvement of geophysical observations and the post-IGY growth of scientific investigations in Italy.

    This paper reviews the main results of the study, carried out in the framework of the Italian National Institute of Nuclear Physics (INFN, Istituto Nazionale di Fisica Nucleare) projects, namely CANDIDO and CONRAD, on natural and synthetic diamond-based dosimeters for clinical radiotherapy. Characteristics of diamond such as radiation hardness, high sensitivity, tissue equivalence, etc., make this material interesting for dosimetry applications. For some years, natural diamonds have been commercially available for on-line radiotherapy dosimetry. Nevertheless, recent developments in the 'Chemical Vapour Deposition' (CVD) technique have addressed the attention on synthetic samples that potentially could be grown at low cost and with features suitable for dosimetric use. Several samples, differently grown and with different electrical contacts, have been compared by measuring their current response during irradiation with high-energy photon, electron and proton beams. Properties of dosimetric interest such as linearity, pre-irradiation dose, dose rate dependence, stability and rise time have been investigated. The results obtained so far within the INFN collaboration demonstrate the suitability of natural diamond detectors for many radiotherapy applications and the great potential of CVD diamond-based devices even though, at present, the commercial natural diamond dosimeters have a better behaviour with respect to the synthetic samples. Further efforts have to be made mainly to improve the dynamic of response and performance stability

    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.

    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 (CO2), 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 CO2 in the atmosphere. The well established activity to assure the metrological traceability of CO2 in the atmosphere will be applied to the determination of CO2 in seawater, by developing suitable reference materials for calibration and control of the sensors during their routine use.

    The increasing availability of high resolution digital elevation models (DEMs) is changing our viewpoint towards Earth surface landforms. Nevertheless, large-coverage, intermediate-resolution DEMs are still largely used, and can be the ideal choice in several applications based on the processing of spatially-integrated information. In 2012 the Istituto Nazionale di Geofisica e Vulcanologia opened a website for the free download of the "TINTALY" Digital Elevation Model (DEM), which covers the whole Italian territory. Since then, about 700 users from 28 different countries have been accredited for data download, and a report of 4 years of data dissemination and use is presented. The analysis of the intended use reveals that the 10 m-resolution, seamless TINITALY DEM is of use for an extremely assorted research community. Accredited users are working in virtually any branch of the Earth Sciences (e.g. Volcanology, Seismology, and Geomorphology), in spatially integrated humanities (e.g. History and Archaeology), and in other thematic areas such as in applied Physics and Zoology. Many users are also working in local administrations (e.g. Regions and Municipalities) for civil protection or land use planning purposes. In summary, the documented activity shows that the dissemination of seamless, large coverage elevation datasets can fertilize the technological progress of the whole society providing a significant benefit to stakeholders.

    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.

    The digital preservation of the unique seismological heritage consisting of historical seismograms and earthquake bulletins, and of related documentation (e.g., observatory logbooks, station books, etc.), is critically important in order to avoid deterioration and loss overtime [Kanamori, 1988]. Dissemination of this seismological material in digital form is of equal importance, to allow reanalysis of past earthquakes using modern techniques and the reevaluation of seismic hazard. This is of particular interest for those areas where little or no earthquake activity has occurred since the last significant historical earthquake.In 2001, the Istituto Nazionale di Geofisica e Vulcanologia (INGV) started an innovative project, Progetto SISMOS (i.e., SISMOgrammi Storici), to scan (i.e., convert into digital form for storage on a computer), at very high resolution,and archive seismological paper records and related material. The Italian Ministry for the Environment originally funded the project to encompass the digitization of seismogram records of the Italian seismic observatories and of associated bulletins

    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.

    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 (18×24 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%.

    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.

    Full Text Available Since the early 1970s, geodetic networks became a most important tool to monitor the present day deformations of the volcanic arc of the Aeolian Islands. The first benchmarks were installed in this region at Lipari and Vulcano Islands and the number of GPS benchmarks increased in time since the early ’90s. These networks were periodically surveyed in the frame of national and international geodynamic projects and for Civil Protection programs devoted to the mitigation of the volcanic hazard. The Istituto Nazionale di Geofisica e Vulcanologia (INGV played a fundamental role in the realization and periodical reoccupation of these networks, with the goal to investigate the tectonic and volcanic processes, still active in this crucial area of the central Mediterranean. An updated GPS velocity map for this region, both for the horizontal and vertical component of land motion, with details for Lipari, Vulcano and Panarea Islands, is provided in this paper. The presented GPS velocity field also includes a set of additional discrete stations located in northern Sicily and Calabria together with data from the available CGPS networks active in southern Italy. Here we show the results from eighteen years of repeated GPS surveys performed in this region in the time span 1995-2013 and the open access AINET-GPS data archive, now freely available for the scientific community. Data will support scientific research and hopefully improve the assessment of volcanic and seismic hazard in this region.

    Full Text Available Instrumental seismic catalogues are an essential tool for the zonation of the territory and the production of seismic hazard maps. They are also a valuable instrument for detailed seismological studies regarding active volcanoes and, above all, for interpreting the magma dynamics and the evolution of eruptive phenomena. In this paper, we show the first instrumental earthquake catalogue of Mt. Etna, for the period 2000-2010, with the purpose of producing a homogeneous dataset of 10 years of seismological observations. During this period, 16,845 earthquakes have been recorded by the seismic network run by the Istituto Nazionale di Geofisica and Vulcanologia, Osservatorio Etneo, in Catania. A total of 6,330 events, corresponding to approximately 40% of all earthquakes recorded, were located by using a one-dimensional VP velocity model. The magnitude completeness of the catalogue is equal to about 1.5 for the whole period, except for some short periods in 2001 and 2002-2003 and at the end of 2009. The reliability of the data collected is supported by the good values of the main hypocentral parameters through the time. The spatial distribution of seismicity allowed the highlighting of several seismogenetic areas characterized by different seismic rates and focal depths. This seismic catalogue represents a fundamental tool for several research aiming to a better understanding of the behavior of an active volcano such as Mt. Etna.

    2016-09-01

    Full Text Available This paper presents an overview of the seismic and volcanic activity occurred during 2014 in the region involved by the TOMO-ETNA seismic active experiment (Mt. Etna, Aeolian Islands and Peloritani-Messina Strait areas. To better characterize the seismicity over the year, three-dimensional hypocenter locations and focal mechanism solutions of a dataset of 678 selected small-to-moderate magnitude earthquakes (0.5 ≤ ML ≤ 4.3 were analyzed. In the framework of the TOMO-ETNA experiment, a temporary seismic network was installed on-land from June to November 2014, both to acquire seismic signals produced by shots and to record the local seismicity. Data collected by the temporary network were used to integrate those deriving from the permanent seismic network operated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV-Osservatorio Etneo (Etna Observatory, thus obtaining a numerically more robust dataset. In agreement with previous analysis and studies, the distribution of the hypocentral locations is well representative of the seismicity that typically characterizes this area. The selected well-constrained 42 fault plane solutions evidence two domains characterized by different motions and style of deformation. In particular, an extensional domain in the northeastern Sicily and a strike-slip regime in the northernmost part of the studied region have been observed.

    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.

    The first part of this study reports on the wide campaign for the extension of the database of both trace and minor elements concentration in diopside by means of μ-PIXE measurements and of luminescence spectra in diopside and wollastonite by means of μ-IL measurements. 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). The latter part of the paper is dedicated to the non-invasive Ion Beam Analyses (IBA) characterisation of six pieces of the “Collezione Medicea”. The collection is exhibited at the Museum of Natural History (University of Firenze) and belonged to the Medici family. It includes artworks made of lapis lazuli manufactured in the 16{sup th} and 17{sup 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.

    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...

    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 results of microwave measurements with a quasi-spherical resonator in humid methane samples realized under laboratory conditions at the Istituto Nazionale di Ricerca Metrologica (INRiM) and under industrial conditions in a natural gas sample made available at the facilities of the Technical Manager of the Spanish Gas System and main supplier of natural gas in Spain (ENAGAS) are reported. Measurements at INRiM included vapor phase and condensation tests on methane samples prepared with amount fractions of water between 600 ppm and 5000 ppm at temperatures between 273 K and 295 K and pressures between 150 kPa and 1 MPa. ENAGAS measurements were performed at ambient temperature, 750 kPa on natural gas sampled from the pipeline and successively humidified at amount fractions of water between 140 ppm and 250 ppm for completeness of the comparison with several humidity sensors and instrumentation based on different technologies. To enhance the sensitivity of the microwave method at low humidity, an experimental procedure based on the relative comparison of the dielectric permittivity of the humid gas sample before and after being subject to a chemical drying process was conceived and implemented. The uncertainty budget and the final sensitivity of this procedure are discussed.

    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.

    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.

    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.

    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).

    The first part of this study reports on the wide campaign for the extension of the database of both trace and minor elements concentration in diopside by means of μ-PIXE measurements and of luminescence spectra in diopside and wollastonite by means of μ-IL measurements. 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). The latter part of the paper is dedicated to the non-invasive Ion Beam Analyses (IBA) characterisation of six pieces of the "Collezione Medicea". The collection is exhibited at the Museum of Natural History (University of Firenze) and belonged to the Medici family. It includes artworks made of lapis lazuli manufactured in the 16th and 17th 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 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.

  16. The Legnaro National Laboratories and the SPES facility: nuclear structure and reactions today and tomorrow

    2016-11-01

    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.

    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+) .

    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.

    Smith, Howard

    2001-01-01

    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.

    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.

    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 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.

    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.

    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.

    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.

    ``Jet Charge'', ``Same Side'' and ``Soft Lepton'' tagging methods were studied to determine the b/barb-quark flavor of B-mesons at the time of production. A sample of almost 10,000 B_u,d arrow l D^(*) X decays collected during the 1992-1995 run was analyzed. Six decay signatures were reconstructed. The efficacy of the tagging methods was demonstrated by revealing the time-dependent flavor oscillations of B^0-mesons and measuring their frequency.

    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. The analysis is based on 81.4 pb-1 of data collected with the Collider Detector at Fermilab, CDF.

    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.

    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.

    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.

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.

  14. 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.

    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.

    Since the 1980's volcano monitoring has undergone stunning changes, evolving from descriptive and sparse observations to a systematic-quantitative approach of science and technology. Surveillance of chemical gas composition and their emission rate is a vital part of efforts in interpreting volcanic activity of observatories since their changes are closely linked with seismicity and deformation swings. In this unruly technology progression, volcanic gas sensing observations have also undergone a profound revolution, for example by increasing observation frequency of SO2 flux from a few samples per day to Hz. In May 2013, a permanent-robotic SO2 dual-camera system was installed by the Istituto Nazionale di Geofisica e Vulcanologia at Stromboli as a part of the ultraviolet scanning spectrometers network FLAME, with the intent to underpin the geochemical surveillance and shed light on degassing and volcanic processes. Here, we present the first results of SO2 flux observed by the permanent SO2 camera system in the period between May 2013 and April 2015. Results are corroborated with the well established FLAME ultraviolet scanning network and also compared with VLP signals from the seismic network.

    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.

  3. On sixteenth-century copies of the reliefs from the Column of Trajan – Two new drawings from an unknown rotulus

    2014-07-01

    Full Text Available This article presents two recently discovered drawings of the reliefs on the Trajan's column. To put them in their proper artistic context, the drawings are compared to known examples of such reproductions of the sixteenth century. Current research questions the attribution of codex ms. 254 in the Biblioteca dell'Istituto Nazionale di Archeologia e Storia dell'Arte in Rome to Jacopo Ripanda. The two series with representations of the column's entire frieze preserved in the Biblioteca (mss. 254 and 320 are therefore considered as two different strings of transmission of a yet to be identified original, from which derive all other drawings of the reliefs on the Trajan's Column. Research directed at the contextualisation of the newly published drawings has confirmed this view. The drawings belong without doubt to one of the two strings of transmission. In addition, an archaeological examination of representational details of this depiction has resulted in the suggestion of a new date for the rotuli from a private collection in Paris.

    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.

    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.

    The Great Recession has caused worldwide tangible costs in terms of cuts in employment and income, which have been widely recognised also as major social determinants of mental health. Italy has not been spared from the financial crisis with severe societal and mental health consequences. In addition, a strong earthquake hit the province of Modena, Italy, in 2012, that is, amid the crisis. In this study, we explored and investigated the possible additional impact of concurrent events such as economic crisis and a natural disaster. Our analysis elaborated data from two local surveys, ICESmo2 (2006) and ICESmo3 (2012), and a national survey carried out in 2013 by the Italian National Institute of Statistics (Istituto Nazionale di Statistica (ISTAT)). A regression model was adopted to distinguish the effect of the crisis and the earthquake. Our analysis confirmed the negative effect of the economic crisis on psychological wellbeing, but within the province of Modena such an effect resulted as even stronger compared with the rest of Italy, particularly within those areas struck by the earthquake. Being hit by a combination of two major negative events might have a significantly increased negative effect on psychological health. The higher repercussion observed is not only attributable to the occurrence of a natural disaster but can be reasonably related to the additional effect of unemployment on psychological dimensions. © The Author(s) 2016.

    2002-11-01

    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)

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.

    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).

    Purpose: This paper describes the system for the dose delivery currently used at the Centro Nazionale di Adroterapia Oncologica (CNAO) for ion beam modulated scanning radiotherapy. Methods: CNAO Foundation, Istituto Nazionale di Fisica Nucleare and University of Torino have designed, built, and commissioned a dose delivery system (DDS) to monitor and guide ion beams accelerated by a dedicated synchrotron and to distribute the dose with a full 3D scanning technique. Protons and carbon ions are provided for a wide range of energies in order to cover a sizable span of treatment depths. The target volume, segmented in several layers orthogonally to the beam direction, is irradiated by thousands of pencil beams which must be steered and held to the prescribed positions until the prescribed number of particles has been delivered. For the CNAO beam lines, these operations are performed by the DDS. The main components of this system are two independent beam monitoring detectors, called BOX1 and BOX2, interfaced with two control systems performing the tasks of real-time fast and slow control, and connected to the scanning magnets and the beam chopper. As a reaction to any condition leading to a potential hazard, a DDS interlock signal is sent to the patient interlock system which immediately stops the irradiation. The essential tasks and operations performed by the DDS are described following the data flow from the treatment planning system through the end of the treatment delivery. Results: The ability of the DDS to guarantee a safe and accurate treatment was validated during the commissioning phase by means of checks of the charge collection efficiency, gain uniformity of the chambers, and 2D dose distribution homogeneity and stability. A high level of reliability and robustness has been proven by three years of system activity needing rarely more than regular maintenance and working with 100% uptime. Four identical and independent DDS devices have been tested showing

    Full Text Available Abstract
    Mapping available data about otter (Lutra lutra distribution according to the 10x10 km grid of the IGMI (Italian Geographical Military Institute national maps on the scale of 1:25000, we evaluated a current otter range of 9900 km2, disjoined in two areas: Molise region in central Italy, and Basilicata, Campania, Calabria and Apulia in southern Italy. Considering the results of an otter genetic census performed in the Pollino National Park and surroundings (southern Italy in 2004, we extrapolated the values of otter density found (0.18-0.20 otters/km of watercourse to the overall Italian otter range and to the linear development of the watercourses hosting otters (3313 km. The correspondent estimates of the Italian population size amounted to, respectively, 481-523 and 596-663 otters. Considering a correction factor based on the mean sprainting intensity reported, since 2000, for each catchment hosting otters, the estimated population size was reduced to 229-257 otters. We argue that a new extensive otter survey is urgently needed and that monitoring by non-invasive genetic sampling is recommended in order to define the population status and trend.

    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. […

    The Istituto Nazionale di Geofisica e Vulcanologia of Italy (INGV) in collaboration with the EDANYA Group (University of Málaga) are proposing a FTRT (Faster Than Real Time) tsunami simulation approach that is being implemented in the NEAMTWS Italian CTSP, namely the Centro Allerta Tsunami (CAT), which is in pre-operational stage starting from 1 October 2014, in the 24/7 seismic monitoring room at INGV. We here present the different versions and capabilities of the NTHMP benchmarked HySEA model, developed by EDANYA Group. HySEA implements a multi-GPU version that can compute in several minutes the maximum amplitude and arrival time of the main tsunami wave in about 17,000 selected locations along the Mediterranean. At the same time, HySEA is implemented in nested meshes with different resolution and multi-GPU environment, which allows much faster than real time (below few minutes) inundation simulations. The performances of the code allows as well the preparation of a huge number of different pre-calculated scenarios that are being used for PTHA and for warning applications. Acknowledgements.

  17. 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.

    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 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.

    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.

    In May 2012, right after the M=5.9 Emilia earthquake, was launched the Istituto Nazionale di Geofisica e Vulcanologia (INGV) photographic gallery on Flickr (https://www.flickr.com/photos/ingv/), to improve the INGV communication strategy. The main goals of this initiative were to inform society of the main ongoing research activities, new scientific discoveries, seismic, volcanic and environmental monitoring and key events at INGV. Specifically, to communicate through photos new results of scientific research in seismology, volcanology and environment, to enhance awareness of the earth sciences and related natural hazard in society. At this time, after about two and a half years from the beginning, have been published about 550 downloadable original photos on Flickr, collected in 45 albums. These were all shot by INGV researchers, technologists and technicians, during field surveys, seismic or volcanic emergencies or key events. Besides the INGV seismic and volcanic monitoring centers, photos document the effects of (i) main recent earthquakes in Italy; (ii) main volcanic eruptions in Italy and worldwide, (iii) Mediterranean sea and ocean tsunamis; (iv) environmental changes and monitoring activities and finally (vi) main events at INGV. Presently, the total number of views is over 2.277.000 with main peaks often in relationships with relevant Italian or worldwide earthquakes and volcanic eruptions. The most popular Photo (San Carlo, Emilia earthquake) has been viewed more than 56,000 times. Because each photo includes a brief scientific description and often is linked to press communicates launched by the INGV press office and to geophysical and geological publications, we believe that this initiative has increased people's awareness of the INGV activity and its role in society, contributing to the scientific outreach of researcher's work. .

    Full Text Available In museums, the biological component of indoor air, called bioaerosol or biological aerosol, is a potential biodeteriogen for graphic collections. The biological particles settling on the surface of artworks find favorable nutritional and environmental conditions for their growth, and promote biodeterioration. As is well known, biological attacks depend on microclimatic conditions; for this reason their control is essential to assess contamination and estimate biological risks. This article presents the partial application of a methodological model, in the National Institute of Graphic Arts (Istituto Nazionale per la Grafica-ING, a museum of international importance in Rome, on a collection of ancient drawings in the Fondo Corsini, preserved in repository no.1. This model is based on an integrated system of biological environmental monitoring (air and surfaces in association with microclimatic monitoring (repository no.1, cabinet no.6, volumes, drawings and outdoor carried out in an interdisciplinary research project.The values of thermohygrometric parameters were stable enough during the monitored month and had no daily fluctuations. The qualitative and quantitative analysis of air contamination and that on the surfaces of drawings did not show a critical situation.This article describes a pilot study which has focused attention on the biological contamination of the graphic collections and is a contribution to standardizing a system of diagnosis-intervention for preventive conservation of organic cultural heritage preserved in museums and in other indoor environments and the protection of the health of operators and visitors.

    Within the SECCO survey we identified a candidate stellar counterpart to the Ultra Compact High Velocity Cloud (UCHVC) HVC274.68+74.70-123 that was suggested by Adams et al. to be a possible mini halo within the Local Group of galaxies. The spectroscopic follow-up of the brightest sources within the candidate reveals the presence of two H ii regions whose radial velocity is compatible with a physical association with the UVHVC. The available data do not allow us to give a definite answer on the nature of the newly identified system. A few alternative hypotheses are discussed. However, the most likely possibility is that we have found a new faint dwarf galaxy residing in the Virgo cluster of galaxies, which we name SECCO 1. Independently of its actual distance, SECCO 1 displays a ratio of neutral hydrogen mass to V luminosity of {{M}H I}/{{L}V}≳ 20, by far the largest among local dwarfs. Hence, it appears to be a nearly starless galaxy and it may be an example of the missing links between normal dwarfs and the dark mini halos that are predicted to exist in large numbers according to the currently accepted cosmological model.

    On 29 December 2013, the Chaparrastique volcano in El Salvador, close to the town of S. Miguel, erupted suddenly with explosive force, forming a more than 9 km high column 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 multi-parametric 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 co-located into multi-parametric 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.

  6. The Sun was Not Born in M67

    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.

    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.

    The planned upgrade of instrumentation sensitivity in the ATLAS experiment of the Large Hadron Collider (LHC), at CERN, calls for a new type of power distribution architecture. Moreover, power supplies require DC-DC power converters able to work in very hostile environment and maintaining high level of Reliability, Availability, Maintainability and Safety (denoted as RAMS requirements) during the experimental activity. Two main issues need to be discussed: first, electronic devices and equipment must operate in very high background of both charged and neutral particles and high static magnetic field and, second, the increase of the radiation background and the requirements of new front-end electronics are indeed incompatible with the current capability of the actual distribution system. The APOLLO R&D collaboration, funded by the Italian Istituto Nazionale di Fisica Nucleare (INFN), aims to study dedicated topologies of both distribution system and DC-DC power converters and to design, build and test demonstrators, developing the needed technology for the industrialization phase. The collaboration has designed a 3kW, 280V-12V converter (MC) based on the Switch in Line architecture (SIL), a DC to DC phase-shifted converter characterized by a disposition in line of the MOSFETs with good soft switching performances, and in the last year many steps have been taken to enhance the power dissipation and the reliability and to improve the general features of the designed converter. In particular a new water heat sink was designed on the basis of TFD simulation accounting for the layout of the specific converter. Experimental activities in order to characterize both thermal and electrical features of the MC confirm the correctness of the adopted design criteria.

    This work reports a method based on correlation functions to convert EPID transit signals into in vivo dose values at the isocenter point, D iso, of dynamic IMRT beams supplied by Varian linac. Dose reconstruction for intensity-modulated beams required significant corrections of EPID response, due to the X-ray component transmitted through multileaf collimator. The algorithm was formulated using a set of simulated IMRT beams. The beams were parameterized by means of a fluence inhomogeneity index, FI, introduced to describe the degree of beam modulation with respect to open beams. This way, all dosimetric parameters involved in D iso reconstruction algorithm, such as the correlation functions, the correction factor for EPID to phantom distance and the modulated tissue maximum ratios, were determined as a function of the FI index. Clinical IMRT beams were used to irradiate a homogeneous phantom, and for each beam, the agreement between the reconstructed dose, D iso, and the dose computed by TPS, D iso,TPS, was well within 5 %. Moreover, the average ratios, R, between the D iso, and D iso,TPS, resulted equal to 1.002 ± 0.030. Thirty-five IMRT fields of 5 different patients undergoing radiotherapy for head-neck tumors were tested and the results were displayed on a computer screen after 2 min from the end of the treatment. However, 350 in vivo tests supplied an average ratio R equal to 1.004 ± 0.040. The in vivo dosimetry procedure here presented is among the objectives of a National Project financially supported by the Istituto Nazionale di Fisica Nucleare for the development of in vivo dosimetry procedures (Piermattei et al. in Nucl Instrum Methods Phys Res B 274:42-50, 2012) connected to the Record-Verify system of the radiotherapy center.

    This work deals with the development of a new gamma detector based on Silicon Drift Detectors (SDDs) to readout large LaBr3:Ce scintillators for gamma-ray spectroscopy and imaging applications. The research is supported by the European Space Agency through the Technology Research Programme (TRP) and by Istituto Nazionale di Fisica Nucleare (INFN) within the Gamma project. The SDDs, produced at Fondazione Bruno Kessler (FBK) semiconductor laboratories, are designed as monolithic arrays of 3 × 3 units, each one of an active area of 8 mm × 8 mm (overall area of 26 mm × 26 mm). The readout electronics and the architecture of the camera are briefly described and then first experimental results coupling the SDD array with a 1'' × 1'' LaBr3:Ce scintillator are reported. An energy resolution of 3% FWHM at 662 keV has been measured at -20°C, better than coupling the same scintillator with a photomultiplier tube. The same scintillator is also used to evaluate position sensitivity with a 1 mm collimated Cs-137 source. The main difficulty in determining the position of the gamma-ray interaction in the crystal is associated to the high thickness/diameter ratio of the crystal (1:1) and the use of reflectors on all lateral and top sides the crystal. This last choice enhances energy resolution but makes imaging capability more challenging because light is spread over all photodetectors. Preliminary results show that the camera is able to detect shifts in the measured signals, when the source is moved with steps of 5 mm. A modified version of the centroid method is finally implemented to evaluate the imaging capability of the system.

  12. Large teleseismic P-wave residuals observed at the Alban Hills volcano, Central Italy

    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 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.

    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.

    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.

  17. Teseo, la clementia e la punizione dei tiranni: esemplarità e pessimismo nel finale della Tebaide

    Federica Bessone

    2010-11-01

    Full Text Available Il ruolo di Teseo e della clementia nel finale della Tebaide si scontrano interpretazioni opposte del poema, in una polarizzazione che riproduce il dibattito critico sull’Eneide. Letture sovversive e pessimistiche, o, al contrario, ottimistiche e celebrative, oscurano la complessità di una chiusa in cui convivono esemplarità e pessimismo, come nelle Supplici di Euripide. La Tebaide è un discorso sul potere che inscrive in sé la coscienza di una crisi; la frattura fra i primi undici libri e il dodicesimo spezza forma epica e discorso politico in due parti complementari e in tensione fra loro: all’epica del nefas si contrappone infine un’epica del vincitore, a una spedizione maledetta una guerra giusta, alla degenerazione del potere assoluto l’apparizione di una regalità clemente; la proposta ideologica del finale sta al resto del poema come il De clementia sta alle tragedie di Seneca: rappresenta uno sforzo di ricostruzione dei valori su cui si fonda l’istituto imperiale. Ripensando in termini attuali l’opposizione fra Atene e Tebe nelle Supplici, Stazio trasforma il confronto euripideo fra democrazia e tirannide in un contrasto fra re e tiranno, fra clementia e inclementia regum, fra Teseo e Creonte. La costruzione del personaggio di Teseo mette in ombra la tradizione catulliana, selezionando i tratti che fanno dell’eroe nazionale ateniese un simbolo politico, adottato dai più vari discorsi del potere. L’associazione di Teseo con la sovranità clemente e con la punizione dei tiranni ha un precedente nell’Hercules furens di Seneca. La moderazione di Teseo in battaglia è illustrata con un paradigma animale (il leone mite con la preda tradizionale nelle esortazioni alla clementia.

  18. Further characterization of the time transfer capabilities of precise point positioning (PPP): the Sliding Batch Procedure.

    In recent years, many national timing laboratories have installed geodetic Global Positioning System receivers together with their traditional GPS/GLONASS Common View receivers and Two Way Satellite Time and Frequency Transfer equipment. Many of these geodetic receivers operate continuously within the International GNSS Service (IGS), and their data are regularly processed by IGS Analysis Centers. From its global network of over 350 stations and its Analysis Centers, the IGS generates precise combined GPS ephemeredes and station and satellite clock time series referred to the IGS Time Scale. A processing method called Precise Point Positioning (PPP) is in use in the geodetic community allowing precise recovery of GPS antenna position, clock phase, and atmospheric delays by taking advantage of these IGS precise products. Previous assessments, carried out at Istituto Nazionale di Ricerca Metrologica (INRiM; formerly IEN) with a PPP implementation developed at Natural Resources Canada (NRCan), showed PPP clock solutions have better stability over short/medium term than GPS CV and GPS P3 methods and significantly reduce the day-boundary discontinuities when used in multi-day continuous processing, allowing time-limited, campaign-style time-transfer experiments. This paper reports on follow-on work performed at INRiM and NRCan to further characterize and develop the PPP method for time transfer applications, using data from some of the National Metrology Institutes. We develop a processing procedure that takes advantage of the improved stability of the phase-connected multi-day PPP solutions while allowing the generation of continuous clock time series, more applicable to continuous operation/monitoring of timing equipment.

    No validated prognostic tool is available for predicting overall survival (OS) of patients with well-differentiated neuroendocrine tumors (WDNETs). This study, conducted in three independent cohorts of patients from five different European countries, aimed to develop and validate a classification prognostic score for OS in patients with stage IV WDNETs. We retrospectively collected data on 1387 patients: (i) patients treated at the Istituto Nazionale Tumori (Milan, Italy; n=515); (ii) European cohort of rare NET patients included in the European RARECAREnet database (n=457); (iii) Italian multicentric cohort of pancreatic NET (pNETs) patients treated at 24 Italian institutions (n=415). The score was developed using data from patients included in cohort (i) (training set); external validation was performed by applying the score to the data of the two independent cohorts (ii) and (iii) evaluating both calibration and discriminative ability (Harrell C statistic). We used data on age, primary tumor site, metastasis (synchronous vs metachronous), Ki67, functional status and primary surgery to build the score, which was developed for classifying patients into three groups with differential 10-year OS: I) Favorable-risk group: 10-year OS ≥70%; II) Intermediate-risk group: 30% ≤10-year OS OS <30%. The Harrell C statistic was 0.661 in the training set, and 0.626 and 0.601 in the RARECAREnet and Italian multicentric validation sets, respectively. In conclusion, based on the analysis of three 'field-practice' cohorts collected in different settings, we defined and validated a prognostic score to classify patients into three groups with different long-term prognoses.

    Full Text Available The aim of the study is to estimate the pension costs incurred for patients with musculoskeletal disorders (MDs and specifi cally with rheumatoid arthritis (RA and ankylosing spondylitis (AS in Italy between 2009 and 2012. We analyzed the database of the Italian National Social Security Institute (Istituto Nazionale Previdenza Sociale i.e. INPS to estimate the total costs of three types of social security benefi ts granted to patients with MDs, RA and AS: disability benefi ts (for people with reduced working ability, disability pensions (for people who cannot qualify as workers and incapacity pensions (for people without working ability. We developed a probabilistic model with a Monte Carlo simulation to estimate the total costs for each type of benefi t associated with MDs, RA and AS. We also estimated the productivity loss resulting from RA in 2013. From 2009 to 2012 about 393 thousand treatments were paid for a total of approximately €2.7 billion. The annual number of treatments was on average 98 thousand and cost in total €674 million per year. In particular, the total pension burden was about €99 million for RA and €26 million for AS. The productivity loss for AR in 2013 was equal to €707,425,191 due to 9,174,221 working days lost. Our study is the fi rst to estimate the burden of social security pensions for MDs based on data of both approved claims and benefi ts paid by the national security system. From 2009 to 2012, in Italy, the highest indirect costs were associated with disability pensions (54% of the total indirect cost, followed by disability benefi ts (44.1% of cost and incapacity pensions (1.8% of cost. In conclusion, MDs are chronic and highly debilitating diseases with a strong female predominance and very signifi cant economic and social costs that are set to increase due to the aging of the population.

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.

  2. Measures of maximum magnetic field in 3 GHz radio frequency superconducting cavities

    International Nuclear Information System (INIS)

    2000-01-01

    Theoretical models have shown that the maximum magnetic field in radio frequency superconducting cavities is the superheating field H sh . For niobium, H sh is 25 - 30% higher than the thermodynamical H c field: H sh within (240 - 274) mT. However, the maximum magnetic field observed so far is in the range H c,max = 152 mT for the best 1.3 GHz Nb cavities. This field is lower than the critical field H c1 above which the superconductor breaks up into divided normal and superconducting zones (H c1 ≤H c ). Thermal instabilities are responsible for this low value. In order to reach H 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 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.

    2011-05-01

    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.

    A new 22 GHz water vapor spectrometer, VESPA-22 (water Vapour Emission Spectrometer for Polar Atmosphere), was installed in July 2016 at the Thule High Arctic Atmospheric Observatory (THAAO) located at Thule Air Base (76.5° N, 68.8° W), Greenland, and participated in the intensive measurement campaign of the Study of the water VApour in the polar AtmosPhere (SVAAP) project. After the campaign VESPA-22 has continued to carry out measurements in an autonomous mode and has now obtained more than 6 months of data. VESPA-22 was designed and built at the Istituto Nazionale di Geofisica and Vulcanologia (INGV) and measures the 22.235 GHz water vapor emission line with a bandwidth of 500 MHz and a frequency resolution of 31 kHz. The collected spectra are inverted using an optimal estimation algorithm in order to retrieve water vapour vertical profiles from about 26 to 72 km with a vertical resolution varying from 4 to 7.5 km. The spectrometer can produce 2 to 4 vertical profiles a day, depending on season and weather conditions. VESPA-22 also measures the atmospheric optical depth at 22 GHz and can therefore provide an estimate of precipitable water vapor (PWV) with a temporal resolution of few minutes. The instrument is calibrated every 30 minutes using noise diodes and tipping curves, and requires a calibration with liquid nitrogen (LN2) only once every few months. We will present water vapor stratospheric profiles over Thule obtained during an almost complete yearly cycle. The retrieved profiles have been compared with the Aura/MLS H2O dataset. During autumn 2016 the two datasets show a mean difference of less than 5% and a correlation coefficient of about 0.9 at all altitudes between 26 to 60 km.

Identification of ROS1 rearrangement is mandatory to permit targeted therapy with specific inhibitors, demonstrating a significantly better survival when compared with conventional chemotherapy. Detection of ROS1 rearrangement is based on in situ (immunohistochemistry, fluorescence in situ hybridization and extractive non-in situ assays. While fluorescence in situ hybridization still represents the gold standard in clinical trials, this technique may fail to recognize rearrangements of ROS1 with some gene fusion partner. On the other hand, immunohistochemistry is the most cost-effective screening technique, but it seems to be characterized by low specificity. Extractive molecular assays are expensive and laborious methods, but they specifically recognize almost all ROS1 fusions using a limited amount of mRNA even from formalin-fixed, paraffin-embedded tumor tissues. This review is a discussion on the present and futuristic diagnostic scenario of ROS1

    We report optical B-band observations with the Large Binocular Telescope (LBT) of the isolated neutron star RBS1774. The stacked image with a total exposure of 2fh5 reveals a candidate optical counterpart at mB = 26.96 ± 0.20 at position α (2000) = 21^h43^m03fs40, δ(2000) = +06degr54^prime17farcs5, within the joint Chandra and XMM-Newton error circles. We analyse archival XMM-Newton observations and derive revised spectral and positional parameters. The predicted optical flux from the extrapolated X-ray spectrum is likely twice as high as reported before. The measured optical flux exceeds the extrapolated X-ray spectral flux by a factor ˜40 (15-60 at 1σ confidence). We interpret our detection and the spectral energy distribution as further evidence of a temperature structure over the neutron star's surface and present a pure thermal model reflecting both the SED and the pulsed fraction of the light curve. Based on observations obtained with XMM-Newton, an ESA science mission with instruments and contributions directly funded by ESA Member States and NASA. Based on data acquired using the Large Binocular Telescope (LBT). The LBT is an international collaboration among institutions in the US, Italy, and Germany.

  7. The Ml Magnitude Scale In Italy

    Gasperini, P.; Lolli, B.; Filippucci, M.; de Simoni, B.

    To improve the reliability of Ml magnitude estimates in Italy, we have updated the database of real Wood-Anderson (WA) and of simulated Wood Anderson (SWA) am- plitudes recently revised by Gasperini (2002). This was done by the re-reading of orig- inal WA seismograms, made available by the SISMOS Project of the Istituto Nazionale di Geofisica (INGV), as well as by the analysis of further Very Broad Band (VBB) recordings of the MEDNET network of INGV for the period from 1996 to 1998. The full operability, in the last five years, of a VBB station located exactly at the same site (TRI) of a former WA instrument allowed us to reliably infer a new attenuation function from the joined WA and SWA dataset. We found a significant deviation of the attenuation law from the standard Richter table at distances larger than 400 km where the latter overestimates the magnitude up to about 0.3 units. We also computed regionalized attenuation functions accounting for the differences in the propagation properties of seismic waves between the Adriatic (less attenuating) and Tyrrhenian (more attenuating) sides of the Italian peninsula. Using this improved Ml magnitude database we were also able to further improve the computation of duration (Md) and amplitude (Ma) magnitudes computed from short period vertical seismometers of the INGV as well as to analyze the time variation of the station calibrations. We found that the absolute amplification of INGV stations is underestimated almost exactly by a factor 2 starting from the entering upon in operation of the digital acquisition system at INGV in middle 1984.

    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.

    Falvella, M. C.; Crisconio, M.; Lupi, T.; Sabatini, P.; Valentini, G.; Viola, F.

    On July 15th 2000 the first MITA (Italian Advanced Technology Minisatellite) was launched from Plesetsk (Russia) by a Cosmos rocket as a piggy-back of the CHAMP satellite. The main purpose of the first MITA mission is its in-flight validation. Furthermore the scientific payload NINA-2 of INFN (Istituto Nazionale di Fisica Nucleare) and the technological payload MTS-AOMS (Micro Tech Sensor for Attitude and Orbit Measurement System) were embarked. The NINA-2 goal is the survey of galactic and solar cosmic rays at 450 km altitude. MTS is an ESA multi-tasking autonomous sensor based on Active Pixel Sensor (star and horizon sensor), Angular Rate Sensor and Magnetic Field Sensor. In this paper the main MITA bus characteristics are reported, together with the description of the launch and the first commissioning phase. The first mission nominal orbit is circular, with a 450 Km altitude and a 87° inclination. The satellite attitude is nadir pointing, 3 axes stabilised. Spacecraft mass is 169.9 Kg. Two fixed solar panels provide an average power of 85 W EOL. The configuration of the satellite main body is based on a cubic shape module, made of Aluminium beams and honeycomb panels. The Mission Control Center is placed in Rome, while the TT&C stations are in Cordoba (Argentina) and, only during the commissioning phase, in Malindi (Kenia); Malindi TT&C station will then be replaced by Fucino (Italy). Since the contacts between spacecraft and the TT&C stations do not occur every orbit, the satellite on board S/W was designed in order to reach the nominal mode without telecommand from ground.

  10. Measurement of the neutron fields produced by a 62 MeV proton beam on a PMMA phantom using extended range Bonner sphere spectrometers

    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 Emeasurements 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° 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.

    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

    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.

    Full Text Available Purpose: The proton therapy presents a great precision during the radiation dose delivery. It is useful when the tumor is located in a sensitive area like brain or eyes. The Monte Carlo (MC simulations are usually used in treatment planning system (TPS to estimate the radiation dose. In this paper we are interested in estimating the proton dose statistical uncertainty generated by the MC simulations. Methods: Geant4 was used in the simulation of the eye’s treatment room for 62 MeV protons therapy, installed in the Istituto Nazionale Fisica Nucleare Laboratori Nazionali del Sud (LNS-INFN facility in Catania. This code is a Monte Carlo based on software dedicated to simulate the passage of particles through the matter. In this work, we are interested in optimizing the Geant4 parameters on energy deposit distribution by proton to achieve the spatial resolution of dose distribution required for cancer therapy. We propose various simulations and compare the corresponding dose distribution inside water to evaluate the statistical uncertainties. Results: The simulated Bragg peak, based on facility model is in agreement with the experimental data, The calculations show that the mean statistical uncertainty is less than 1% for a simulation set with 5 × 104 events, 10-3 mm production threshold and a 10-2 mm step limit. Conclusion: The set of Geant4 cut and step limit values can be chosen in combination with the number of events to reach precision recommended from International Commission on Radiation Units and measurements (ICRU in Monte Carlo codes for proton therapy treatment.

    Full Text Available Volcanic activity has often affected human life both at large and at small scale. For example, the 2010 Eyjafjallajokull eruption caused severe economic damage at continental scale due to its strong effect on air traffic. At a local scale, ash fall and lava flow emission can cause harm and disruption. Understanding precursory signals to volcanic eruptions is still an open and tricky challenge: seismic tremor and gas emissions, for example, are related to upcoming eruptive activity but the mechanisms are not yet completely understood. Furthermore, information related to gases emission mostly comes from the summit crater area of a volcano, which is usually hard to investigate with required accuracy. Although many regulation problems are still on the discussion table, an increasing interest in the application of cutting-edge technology like unmanned flying systems is growing up. In this sense, INGV (Istituto Nazionale di Geofisica e Vulcanologia started to investigate the possibility to use unmanned air vehicles for volcanic environment application already in 2004. A flight both in visual- and radio-controlled mode was carried out on Stromboli volcano as feasibility test. In this work we present the preliminary results of a test performed by INGV in collaboration with the University of Bologna (aerospace division by using a multi-rotor aircraft in a hexacopter configuration. Thermal camera observations and flying tests have been realised over a mud volcano located on its SW flank of Mt. Etna and whose activity proved to be related to early stages of magma accumulation within the volcano.

    From 2011 to 2014, the BESIII experiment collected about 5 fb-1 data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states. By analyzing the di-muon process e+e- → γISR/FSRμ+μ-, the center-of-mass energies of the data samples are measured with a precision of 0.8 MeV. The center-of-mass energy is found to be stable for most of the time during data taking.

    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.

    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.

    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.

    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.

    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.

    We present the measurement of the average lifetime of b-hadrons produced in pbarp collisions at √s = 1.8 TeV weighted by their branching ratios into J/ψ We use dimuon data which corresponds to an integrated luminosity of ≈ 90 pb-1 recorded with the CDF-detector during the 1994 to 95 running period. After all selection cuts and background subtraction we are left with a high statistics sample of 62656 J/ψ decaying into μ^+μ^- reconstructed in the CDF Silicon VerteX detector (SVX) where 17.8% of these events come from b-decays. We measure the average B lifetime to be 1.52 ; ± 0.015; (stat);^+0.038_-0.027;(sys); ps (preliminary). The precision of this measurement is significantly improved compared to the inclusive lifetime measurement published previously using ≈ 10 pb-1 of data recorded in 91-92. ^ Supported by U.S. DOE DE-AC03-76SF00098. ^ Supported by U.S. DOE DEFG03-95-ER-40938. ^*We thank the Fermilab staff and the technical staffs of the participating institutions for their vital contributions.

    During the 8th class the students learn geology. We analyze the earth's layers, the earthquakes, the volcanoes and other natural phenomena like subduction and orogeny. We start with a global study but our goal is to focus on the crust to discover the plates boundaries, particularly the boundary between Eurasian and African Plate in the Mediterranean sea. It's very simple for the students to discover all the information using the Internet or the science book, but I want to make with them an exploration of earth science with the help of the natural phenomena we studied during the year. We connect with Istituto Nazionale di Geofisica e Vulcanologia ( http://www.ingv.it/en/ ) where we can find a map with the earthquakes happened in the last years in Italy and in the Mediterranean sea and the list of the main volcanoes. In this way we can draw a map of the mediterranean plates and we can talk about the past and the future of the Mediterranean sea, Europe and Africa based on our maps and on the Alps orogeny. Using youtube we can have a confirm of our hypothesis about the future of the Mediterranean sea (https://www.youtube.com/watch?v=uGcDed4xVD4 ). A good observation for the students is given by the fact that we live in Europe but actually we stay on the African plate. The boundary is 5 km north of our school and we can go and visit the place where it is possible to see the different height of the two plates.

    Since 2002 the OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Udine (Italy), the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Vienna (Austria), and the Agencija Republike Slovenije za Okolje (ARSO) in Ljubljana (Slovenia) are using the Antelope software suite as the main tool for collecting, analyzing, archiving and exchanging seismic data in real time, initially in the framework of the EU Interreg IIIa Italia-Austria project "Trans-national seismological networks in the South-Eastern Alps". The data exchange has proved to be effective and very useful in case of seismic events near the borders between Italy, Austria and Slovenia, where the poor single national seismic networks coverage precluded a correct localization, while the usage of common data from the integrated networks improves considerably the overall reliability of real time seismic monitoring of the area. Up to now the data exchange between the seismic data centres relied on internet: this however was not an ideal condition for civil protection purposes, since internet reliability is poor. For this reason in 2012 the Protezione Civile della Provincia Autonoma di Bolzano in Bolzano (Italy) joined OGS, ZAMG and ARSO in the Interreg IV Italia-Austria project "SeismoSAT" aimed in connecting the seismic data centres in real time via satellite. As already presented in the past, the general technical schema of the project has been approved, data bandwidths and monthly volumes required have been quantified, the common satellite provider has been selected and the hardware has been purchased and installed. We will here illustrate the SeismoSAT project final tests and results.

    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.

    Imatinib showed activity in 50 chordoma patients treated within a Phase II study. In that study, 70% of patients remained with stable disease (SD), median progression free survival (PFS) was 9 months and median overall survival (OS) was 34 months. We now report on a retrospective series of PDGFB/PDGFRB positive advanced chordoma patients treated with imatinib as a single agent within a compassionate-use programme at Istituto Nazionale Tumori, Milan, Italy (INT) between August 2002 and November 2010, when the programme was closed. 48 patients were consecutively treated with imatinib 800 mg/d. All patients had inoperable and progressive disease before starting imatinib. Demographics, treatment duration, toxicity and response rate by Response Evaluation Criteria in Solid Tumors (RECIST) were retrospectively recorded. The median duration of therapy was 7 months (1-46.5). No patient is on therapy at present. 46 patients were evaluable for response. No partial responses were detected. Best response was: stable disease 34 (74%), progressive disease 12 (26%). At a median follow-up of 24.5 months (0.5-117), median PFS was 9.9 months (95% confidence interval (CI) 6.7-13). Eight patients (16.5%) remained on therapy >18 months and 10 patients (21%) remained progression-free >18 months. Median OS was 30 months (95% CI 20-40), with 24 (50%) patients dead at the time of the present analysis. We confirm the activity of imatinib in locally advanced and metastatic chordoma, in terms of >70% tumour growth arrest in previously progressive patients. Median duration of response lasted almost 10 months, with >20% of patients progression-free at 18+ months. Copyright © 2015 Elsevier Ltd. All rights reserved.

    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.

    Full Text Available n February 2010, we launched an experimental scientific video channel on YouTube (http://www.youtube.com/ingvterremoti, to improve our communication strategy for earthquake risk and preparedness. 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.

  14. Turning the rumor of the May 11, 2011, earthquake prediction in Rome, Italy, into an information day on earthquake hazard

    2012-07-01

    Full Text Available A devastating earthquake was predicted to hit Rome on May 11, 2011. This prediction was never officially released, but it grew on the internet and was amplified by the media. It was erroneously ascribed to Raffaele Bendandi, an Italian self-taught natural scientist who studied planetary motions and related them to earthquakes. Indeed, around May 11, 2011, there was a planetary alignment, and this fed the credibility of the earthquake prediction. During the months preceding May 2011, the Istituto Nazionale di Geofisica e Vulcanologia (INGV was overwhelmed with requests for information about this prediction, by the inhabitants of Rome and by tourists. Given the echo of this earthquake prediction, on May 11, 2011, the INGV decided to organize an Open Day at its headquarters in Rome, to inform the public about Italian seismicity and earthquake physics. The Open Day was preceded by a press conference two days before, to talk with journalists about this prediction, and to present the Open Day. During this ‘Day’, 13 new videos were also posted on our YouTube/INGVterremoti channel to explain earthquake processes and hazards, and to provide periodic updates on seismicity in Italy from the seismicity monitoring room. On May 11, 2011, the INGV headquarters was peacefully invaded by over 3,000 visitors, from 10:00 am to 9:00 pm: families, students with and without teachers, civil protection groups, and many journalists. This initiative that was built up in a few weeks has had very large feedback, and was a great opportunity to talk with journalists and people about earthquake prediction, and more in general about the seismic risk in Italy.

    Full Text Available Geochemical surveys were performed by the Istituto Nazionale di Geofisica (ING, between December 1990 and July 1991, in the framework of an interdisciplinary task study throughout the Siracusa epicentral area: these studies were aimed at col1ecting specific information on the geochemical patterns of fluids, in relation to the geodynamic and seismic evolution of the nol1hern Iblean Foreland area, stal1ing from the December, 13, 1990 Syracuse earthquake (M = 5,4. The results of the hydrogeochemical surveys, discussed in this paper, were in part unexpected. In particular, a steady decrease of the PCO2 va1ues, after the eal1hquake, in ground- waters of the epicentral area, along a NNW-SSE fault bordering the Augusta Graben (Brucoli Sulphureous Spring, was observed. This observation enabled us to reconstruct the geochemical processes triggered by the earthquake: a sudden and strong release of CO2 of deep origin, probably related to a pore pressure uprising and/or to a water/rock interaction changes in the vicinity of the seismogenic structure. The existence of deep- fluid uprising (CO2, 222Rn, NHj, H2S, as well as the variation in time of geochemica1 flows accompanying seismic activity along this NNW-SSE anomalous-sites 1ine, within the whole Iblean Foreland, witnes., the activity (as concern as fluidodynamic and geochemistry of the NNW-SSE striking Ibleo-Maltese Escarpment fault system. This fact can be taken into account in locating the seismogenic structure responsible for the 1990 earthquake, like a contribution of the geochemical methods applied to seismotectonics. During June 1992, a more complete ana1ysis of the Iblean Foreland groundwaters was performed, co1lecting data on the geochemi- ca1 feature, of the different aquifers in aseismic period. Mu1tivariable statistics, chemical equilibria studies and mapping with our geochemical data, were also performed.

    Chest wall reconstruction after surgical resection for malignancies in children is a challenge for surgeons because of growth-related complications. The aim of this study is to analyze the surgical treatment and outcomes of 30 pediatric and adolescent patients treated at Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy, over a 30-year period. Pediatric patients undergoing chest wall resection were retrospectively reviewed and selected for malignant primary tumor. Endpoints were survival, recurrences, and long-term results. We also reported the use of the innovative rib-like technique in 2 young patients. Twenty-one patients were male. Median age was 13.7 years. Eleven patients (37%) presented with a chest wall mass. Twenty-six (87%) had Ewing sarcoma family tumors. Twenty-eight (94%) received neoadjuvant chemotherapy after histologic diagnosis. One rib was resected in 13 cases; 2 or 3 contiguous ribs in 8 cases. No postoperative mortality was observed and the complication rate was 40%. Overall survival was 85.2% (95% confidence interval [CI] 65.2%-94.2%) at 5 and 10 years. Relapse occurred in 7 patients. The 5-year disease-free survival rate was 82% (95% CI 62%-92%). Long-term survival is achievable for chest wall tumors in a high-volume referral center where a multimodal treatment should be set to reach the best result. As advances in medical treatment have increased survival, surgical techniques must ensure a lasting functional result. When refining the reconstruction techniques, such as the rib-like approach, it is necessary to expand the options of curative surgery for young patients.

    the compositional investigation based on imaging spectroscopy data collected at shorter wavelengths. In the VIRTIS thermal images, a note of great interest is provided by the 'neck' of the comet close to the 'body', where, because of the concave shape, the 'head' casts prominent shadows on some areas when they experience maximum daily insolation. This is a place potentially subjected to considerable thermal stresses. We evaluate both the spatial thermal gradients and the temporal thermal gradients, providing implications for the surface structure.

    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.

    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.

    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.

    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.

    For many years creatine kinase (CK) and CK-MB isoenzymes were used together with the ECG to confirm the presence of myocardial infarction. During the last decade newer cardiac markers have been introduced and immunological test systems developed for their quantification. Among these new markers, a prominent role has emerged for cardiac troponins (T or I). These technological advanced assays have shown greater sensitivity compared to "conventional cardiac enzymes;, thereby identifying patients with small--at times, microscopic--infarcts who would not have met defining criteria for myocardial infarction in an earlier era. Another major advantage shown by both cardiac troponins with respect to "conventional cardiac enzymes" is their ability to predict clinical outcome over a short- or long-term follow-up in patients with acute coronary syndromes, and this appears to be particularly relevant in patients with micronecrosis, who constitute a high-risk subgroup of unstable angina patients. Recently, myoglobin has also been widely applied as a marker. Although lacking in myocardial specificity, it is the earliest marker to show an increase after coronary occlusion. Thus, the combined use of myoglobin and a cardiospecific structural protein such as troponin T or I may prove an attractive strategy for biochemical testing in chest pain patients. With the routine use of these novel cardiac markers, fascinating opportunities are now open in the field of diagnostic classification (making the World Health Organization definition of myocardial infarction obsolete) and risk stratification in chest pain patients; opportunities that were unforeseen in the era of cardiac enzymes. However, the use of these markers has also posed some important questions on: a) the best and most cost-effective diagnostic strategy in chest pain patients; b) the remaining role of cardiac enzymes; c) the therapeutic consequences of a positive test result.

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

    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

    It was with great pleasure that the Department of Nuclear and Theoretical Physics of the University of Pavia and the INFN (Istituto Nazionale di Fisica Nucleare) Structure of Pavia organised the XIX Nuclear Physics Divisional Conference of the European Physical Society, which was held in the historical buildings of the University of Pavia from 5-9 September 2005. The Conference was devoted to the discussion of the most recent experimental and theoretical achievements in the field of Nuclear Physics applications, as well as of the latest developments in technological tools related to Nuclear Physics research. The University of Pavia has a long tradition in Physics and in Applied Physics, being the site where Alessandro Volta developed his "pila", the precursor of the modern battery. This is the place where the first experiments with electricity were conducted and where the term "capacitance" used for capacitors was invented. Today the University hosts a Triga Mark II nuclear reactor, which is used by the Departments of the University of Pavia and by other Universities and private companies as well. Moreover, Pavia is the site selected for the construction of the CNAO complex "Centro Nazionale di Adroterapia Oncologica" (National Centre for Oncological Hadrontherapy), planned for 2005-2008 which represents a unique facility in Italy and will be among the first complexes of this type in Europe. The Conference has gathered together experts in various fields from different countries and has been the occasion to review the present status and to discuss the new emerging trends in Nuclear Physics and its applications to multidisciplinary researches and the development of new technologies. The following topics were treated: Nuclear Techniques in Medicine and Life Sciences (Cancer Therapy, new Imaging and Diagnostics Tools, Radioisotope production, Radiation Protection and Dosimetry). Applications of Nuclear Techniques in Art, Archaeometry and other Interdisciplinary fields

    In February 2001 the Internal Dosimetry Laboratory of ENEA Institute for Radioprotection carried out a measurement campaign of atmospheric aerosol in a museum, in the urban area of Bologna, in the frame of GIANO project of ENEA. The aerosol mass size distribution was measured and a high mass concentration of aerosol, 39.5 {mu}g/m{sup 3}, with an aerodynamic diameter less than 0.5 {mu}m was found. A comparison with the composition of the outdoor aerosol was made as well. In an urban area fine particles are generally generated by vehicles exhaust (particularly diesel-powered ones) and are constituted essentially of carbon black. Because of their surface adsorption properties these carbon black particles typically contain varying quantities of substances. Deposition of fine particles on the surfaces of works of art can lead to visual degradation and further damages due to chemical reactions with the adsorbed compounds. [Italian] Nell'ambito del progetto di Grafica Innovativa per il patrimonio Artistico Nazionale e per l'Occupazione Giovanile (GIANO) dell'ENEA, il laboratorio di dosimetria interna dell'Istituto per la Radioprotezione dell'ENEA, che ha competenze nella caratterizzazione fisica dell'aerosol, ha effettuato una campagna preliminare di misura del particolato aerosospeso presente all'interno di un museo nell'area urbana della citta' di Bologna. I dati dei campionamenti hanno rilevato la presenza di un'alta concentrazione in massa, 44.7 {mu}/m{sup 3}, di particolato aerosospeso inferiore a 10.5 {mu}m, composta per circa il 90%, 39.5% {mu}/m{sup 3}, da particelle con diametro aerodinamico inferiore a 0.5 {mu}m. La provenienza dalle emissioni dei motori a combustibili fossili, del particolato con queste dimensioni, ha consentito il confronto con i dati relativi alle misure di concentrazione di particolato aerosospeso effettuate presso un incrocio ad alta intensita' di traffico della citta'.

    The acronym "C6" means "Climatic Changes and Carbon Cycle in Canyons and Caves". The project was born in 2005, joining under the scientific supervision of the Palermo branch of the Istituto Nazionale di Geofisica e Vulcanologia two different programs both active since 1999; the first was due to the initiative of the Italian Canyoning Association, a no-profit association aimed to the diffusion of the canyoning sport practise in Italy, the second one, developed by the NGO Legambiente Sicilia and funded by the Regione Siciliana-Assessorato Territorio e Ambiente (Sicilian Regional Government, Territorial and Environmental Department), managing the natural reserves of Santa Ninfa, Carburangeli and Sant'Angelo Muxaro caves (Sicily), was focused to verify the existence of a possible environmental negative feedback of human fruition. In 2005 the Royal Society for the Conservation of Nature of Jordan joined the program, and a new site was established inside the Shagher Daghleh Canyon in the Wadi Dana Reserve. In October 2006 the Caver Federation of Bosnia Herzegovina joined the C6 program and another observational site was instituted into a cave close to Sarajevo. Preliminary data acquired indicate how canyons play a very important role in biodiversity preservation in arid and semi-arid environments, whereas caves are extraordinary natural laboratories for the study of carbon dioxide partition between atmosphere and lithosphere, of the effect of rain dynamic on the underground aquifer recharge and, last but not least, of the monitoring of climatic changes. The success of the initiative is based on the very different nature of the co-participants. Caver and canyoning associations guarantee the safe accessibility to difficult environments, like canyons and caves. The selection as measuring sites of natural reserves managed by NGOs, whose activity is essentially based on volunteers, ensure on one hand their environmental stability on a long term perspective, on the other hand

    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, organizes every year intense educational and outreach activities to convey scientific knowledge and to promote research on Earth Science, focusing on volcanic and seismic hazard. Focusing on kids, we designed and implemented the "greedy laboratory for children curious on science (Laboratorio goloso per bambini curiosi di scienza)", to intrigue children from primary schools and to attract their interest by addressing in a fun and unusual way topics regarding the Earth, seismicity and seismic risk. We performed the "greedy laboratory" using experiential teaching, an innovative method envisaging the use and handling commonly used substances. In particular, in the "greedy laboratory" we proposed the use of everyday life's elements, such as food, to engage, entertain and convey in a simple and interesting communication approach notions concerning Earth processes. We proposed the initiative to public during the "European Researchers Night" in Rome, on September 26, 2014. Children attending the "greedy laboratory", guided by researchers and technicians, had the opportunity to become familiar with scientific concepts, such as the composition of the Earth, the Plate tectonics, the earthquake generation, the propagation of seismic waves and their shaking effects on the anthropogenic environment. During the hand-on laboratory, each child used not harmful substances such as honey, chocolate, flour, barley, boiled eggs and biscuits. At the end, we administered a questionnaire rating the proposed activities, first evaluating the level of general satisfaction of the laboratory and then the various activities in which it was divided. This survey supplied our team with feedbacks, revealing some precious hints on appreciation and margins of improvement. We provided a semi-quantitative assessment with a

    Full Text Available The first modern studies of seismicity in Italy date back to the late 60's and early 70's. Although with a sparse seismic network available and only a few telemetered short-period stations, significant studies were carried out that outlined the main features of Italian seismicity (see, e.g., Boschi et al., 1969. Among these studies, one of the most important achievements was the reconnaissance of a Wadati-Benioff zone in Southern Tyrrhenian, described for the first time in detail in the papers of Caputo et al.(1970, 1973. Today, after three decades of more and more detailed seismological monitoring of the Italian region and tens of thousands earthquakes located since then, the knowledge of the earthquake generation processes in our country is much improved, although some of the conclusions reached in these early papers still hold. These improvements were made possible by the efforts of many institutions and seismologists who have been working hard to bring seismological research in Italy to standards of absolute quality, under the pivoting role of the Istituto Nazionale di Geofisica (ING. From the relocation of about 30000 crustal earthquakes and detailed studies on intermediate and deep shocks carried out in the last few years, we show that seismic release in peninsular Italy is only weakly related to the Africa-Eurasia convergence, but rather is best explained by the existence of two separate subduction/collision arcs (Northern Apennines and Southern Apennines-Calabria-Sicily. The width of the deforming belt running along peninsular Italy is 30 to 60 km, it is broader in the north than in the south, and the two arcs are separated by a region of more distributed deformation and stress rotations in the Central Apennines. Along the belt, the reconnaissance of regions of continuous and weak release of seismic energy, adjacent to fault areas which are currently «locked» (and therefore are the best candidates for future earthquakes is another

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.

    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

    Italy is a country prone to Earth phenomena such as earthquakes, volcanic eruptions, floods and landslides that left a trace in the memory of people. About 60% of the Italian territory is classified in the current seismic hazard maps, and large cities as Neaples and Catania are located close to the two largest active volcanoes of Europe (Mt. Vesuvius and Mt. Etna, respectively). Nevertheless, school programs are often inadequate about the natural hazards of the country. For this reason there are many requests from schoolteachers to visit with their classes the academic Institutions and to attend geophysical talks. The working group for educational activities of the Istituto Nazionale di Geofisica and Vulcanologia promotes and realizes Earth science outreach programs devoted to increase the knowledge of geophysical topics. The educational activity is one of the most important tasks of our Institution together with the research activities and the 24-hours survey of the Italian Seismic Network. The INGV hosts in its headquarter of Rome many visits of primary, secondary and high schools with an increasing demand year by year. Every year about 3,000 students visit our Institute over more than 60 open-days, and we participate to exhibitions and outreach projects organized by several Institutions. We show here what has been done at INGV for the geophysical education, underlining the problems and the successes of these activities. We describe also an educational project developed together with a teacher's team of secondary-school. Aim of this experience was to stimulate the interest of 12-year-old kids to unfamiliar arguments like seismology. The class was introduced to physical topics as waves and wave propagation by means of simple experiments. Then they visited the INGV were the research activities were shown, with emphasis on seismological studies; they were also thought how the Italian Seismic Network monitors earthquakes and how to use the P and S waves for their

    Under perturbed conditions caused by intense solar wind magnetosphere coupling, the ionosphere may become highly turbulent and irregularities, typically enhancements or depletions of the electron density embedded in the ambient ionosphere, can form. Such irregularities cause diffraction effects, mainly due to the random fluctuations of the refractive index of the ionosphere, on the satellites signals passing through them and consequent perturbations may cause GNSS navigation errors and outages, abruptly corrupting its performance. Due to the morphology of the geomagnetic field, whose lines are almost vertical at high latitude, polar areas are characterized by the presence of significant ionospheric irregularities having scale sizes ranging from hundreds of kilometers down to a few centimeters and with highly dynamic structures. The understanding of the effect of such phenomena is important, not only in preparation for the next solar cycle (24), whose maximum is expected in 2012, but also for a deeper comprehension of the dynamics of the high-latitude ionosphere. We analyze the fluctuations in the carrier frequency of the radio waves received on the ground, commonly referred to as ionospheric amplitude and phase scintillations, to investigate the physical processes causing them. The phase scintillations on GNSS signals are likely caused by ionospheric irregularities of scale size of hundreds of meters to few kilometers. The amplitude scintillations on GNSS signals are caused by ionospheric irregularities of scale size smaller than the Fresnel radius, which is of the order of hundreds of meters for GNSS signals, typically embedded into the patches. The Istituto Nazionale di Geofisica e Vulcanologia (INGV) and the Institute of Engineering Surveying and Space Geodesy (IESSG) of the University of Nottingham manage the same kind of GISTM (GPS Ionospheric Scintillation and TEC Monitor) receivers over the European high and mid latitude regions and over Antarctica.

These EPOS members have all implemented GSAC at their respective data centers for internal testing and/or public utilization. In the US, GSAC has been successfully used in both repository and federated implementations at three data centers, each maintaining their own local information architecture to manage their respective data and metadata holdings. These capacities of GSAC will also be utilized in the EPOS context. Lessons have been learned through the GSAC installations so far that show the way for augmenting data center information architecture to both maximize the capabilities of GSAC to allow unified data and metadata presentation for search and access.

    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

    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

    Context. High-resolution échelle spectra confine many essential stellar parameters once the data reach a quality appropriate to constrain the various physical processes that form these spectra. 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.

    The Open Archive Initiative (OAI) refers to a movement started around the '90 s to guarantee free access to scientific information by removing the barriers to research results, especially those related to the ever increasing journal subscription prices. This new paradigm has reshaped the scholarly communication system and is closely connected to the build up of institutional repositories (IRs) conceived to the benefit of scientists and research bodies as a means to keep possession of their own literary production. The IRs are high-value tools which permit authors to gain visibility by enabling rapid access to scientific material (not only publications) thus increasing impact (citation rate) and permitting a multidimensional assessment of research findings. A survey was conducted in March 2010 to mainly explore the managing system in use for archiving the research finding adopted by the Italian Scientific Institutes for Research, Hospitalization and Health Care (IRCCS) of the oncology area within the Italian National Health Service (Servizio Sanitario Nazionale, SSN). They were asked to respond to a questionnaire intended to collect data about institutional archives, metadata formats and posting of full-text documents. The enquiry concerned also the perceived role of the institutional repository DSpace ISS, built up by the Istituto Superiore di Sanità (ISS) and based on a XML scheme for encoding metadata. Such a repository aims at acting as a unique reference point for the biomedical information produced by the Italian research institutions. An in-depth analysis has also been performed on the collection of information material addressed to patients produced by the institutions surveyed. The survey respondents were 6 out of 9. The results reveal the use of different practices and standard among the institutions concerning: the type of documentation collected, the software adopted, the use and format of metadata and the conditions of accessibility to the IRs.

    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.

    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

    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

Current antiemetic guidelines recommend that the neurokinin-1 receptor (NK-1R antagonist aprepitant should be used as part of a combination regimen with dexamethasone and a serotonin receptor antagonist for the prevention of CINV in patients receiving highly emetogenic chemotherapy (HEC. Fosaprepitant is a water-soluble N-phosphoryl derivative of aprepitant that, when infused, is rapidly metabolized back to an active aprepitant. The existing literature in PubMed about fosaprepitant was screened and selected in order to address the emerging data from two randomized clinical trials evaluating the efficacy and safety of a single-dose fosaprepitant regimen. These phase III trials demonstrated that fosaprepitant given as a single intravenous dose of 150 mg was either noninferior to the conventional 3-day aprepitant or significantly superior to placebo for the prevention of acute and delayed CINV in patients receiving high-dose cisplatin. In both trials, fosaprepitant was well tolerated although more frequent infusion-site adverse events were observed with fosaprepitant. The new dosage regimen of fosaprepitant, therefore, would be an option for CINV control in patients receiving cisplatin-based chemotherapy. The clinical efficacy is consistent with the findings from a time-on-target, positron-emission tomography study evaluating the NK-1R occupancy in the central nervous system (CNS over 5 days after a single-dose infusion of 150 mg fosaprepitant in healthy participants. The single-dose regimen is capable of blocking more than 90% of the NK-1Rs in the CNS for at least 48 hours after infusion, which is sufficient

    The present study was aimed at surveying the Italian food consumption patterns in the 90s. It represented the second nationwide food intake survey that was carried out by the Istituto Nazionale di Ricerca per gli Alimenti e la Nutrizione (INRAN). Cross-sectional study. Free-living households. Sampled subjects: 1147 households randomly selected to be representative of the four main geographical areas (North-West, North-East, Centre, South). Analysed subjects: 1978 individuals out of 2734 initially collected in 15 Collaborative Centres strategically scattered through the national territory. A mixed 7-day based survey technique was applied in order to survey both individual and household consumption. At individual level, food intake was recorded by a self-compiled diary. At household level food data collection was by compilation of a food inventory by the dietician, a purchased/wasted foods diary and a recipes form both compiled by the person responsible for food related activities (decision of purchase, purchase, preparation of meals) in the household. All recorded data were monitored by the dieticians who visited the households participating in the study, at least three times. Household members were interviewed in order to collect socio-demographic, lifestyle and motivational information. Furthermore, field-workers performed the food coding and the input of data by an ad hoc developed software. The survey design allowed an internal quantitative check of food data. Several check steps were centrally performed The complex methodology caused the 46.8% response rate and afterwards a reduction of the analysed units (72% of the surveyed individuals). However, the analysed sample provided sufficiently reliable data for outlining the most relevant aspects of dietary patterns in Italy. In order to better interpret the results, controversial aspects are also illustrated and discussed in the text. The disparity analysis found that traditional diversities among Italian regions

    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

    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

    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.

    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.

    Full Text Available Abstract Background The evaluation of cancer patients needs, especially during that delicate period when they are hospitalized, allows the identification of those areas of care that require to be improved. Aims of the study were to evaluate the needs in cancer inpatients and to improve the understanding of the meanings of the needs expressed. Methods The study was conducted during a "sample day", with all the cancer patients involved having been hospitalized at the Istituto Nazionale Tumori of Milan (INT for at least 48 hours beforehand. The study was carried out using quantitative and qualitative methodologies. The quantitative part of the study consisted in making use of the Needs Evaluation Questionnaire (NEQ, a standardized questionnaire administered by the INT Psychology Unit members, supported by a group of volunteers from the Milan section of the Italian League Against Cancer. The aim of the qualitative part of the study, by semi-structured interviews conducted with a small sample of 8 hospitalized patients, was to improve our understanding of the meanings, implications of the needs directly described from the point of view of the patients. Such an approach determines the reasons and conditions of the dissatisfaction in the patient, and provides additional information for the planning of improvement interventions. Results Of the 224 eligible patients, 182 (81% completed the questionnaire. Four of the top five needs expressed by 40% or more of the responders concerned information needs (diagnosis, future conditions, dialogue with doctors, economic-insurance solutions related to the disease. Only one of the 5 was concerned with improved "hotel" services (bathrooms, meals, cleanliness. Qualitative analysis showed that the most expressed need (to receive more information on their future conditions has the meaning to know how their future life will be affected more than to know his/her actual prognosis. Conclusions Some of the needs which

    Since 2002 OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Udine (Italy), the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Vienna (Austria), and the Agencija Republike Slovenije za Okolje (ARSO) in Ljubljana (Slovenia) are using the Antelope software suite as the main tool for collecting, analyzing, archiving and exchanging seismic data in real time, initially in the framework of the EU Interreg IIIA project "Trans-national seismological networks in the South-Eastern Alps" (Bragato et al., 2004, 2010). The data exchange has proved to be effective and very useful in case of seismic events near the borders between Italy, Austria and Slovenia, where the poor single national seismic networks coverage precluded a correct localization, while the usage of common data from the integrated networks improves considerably the overall reliability of real time seismic monitoring of the area (Fig. 1). At the moment the data exchange between the seismic data centers relies on their internet connections: this however is not an ideal condition for civil protection purposes, since the reliability of standard internet connections is poor. For this reason in 2012 the Protezione Civile della Provincia Autonoma di Bolzano in Bolzano (PCBZ, Italy), OGS, ZAMG subsidiary in Tirol (ZAMG Tirol) and ARSO joined in the Interreg IV Italia-Austria Project "SeismoSAT" (Progetto SeismoSAT, 2012) aimed in connecting the seismic data centers in real time via satellite. ARSO does not belong to the Interreg Italia-Austria region: for this reason ARSO joined the SeismoSAT project as an "associated partner", which, according to Interreg rules can not be funded. ARSO participation in the project is therefore at the beginning limited in benefiting only indirectly from improvement in the robustness of the data exchange between the other data centers, while eventually fully taking part in the project if other sources of funding will be available. The project is in a

    The Educational & Outreach Group (EOG) of the Istituto Nazionale di Geofisica & Vulcanologia created a portable museum to provide educational opportunities in volcanology, volcanic risk and Earth science for students and visitors. The EOG developed this project for the "Festival della Scienza", organized in Genoa, Italy, in October - November, 2007, which was a parade of over 200 events, including scientific and technological exhibitions, workshops, meetings, lectures, books and video presentations. In this museum visitors can successively see many posters and movies and play with interactive exhibits. A little 3D-movie shows the Big Bang, the formation of Solar System and, in particular the formation of the Earth. Many interactive exhibits illustrate why, where and when earthquakes and volcanic eruptions occur around the world and allow to introduce the visitor to the plate tectonics theory. A 3D magnetic plate tectonic puzzle can be put down and reconstructed by visitors to understand the Earth's surface configuration. Then two other 3D Earth models show what drives the plates and the inner Earth structure. An interactive program illustrates where and when earthquakes and volcanic eruptions occur in accelerated time on maps of various areas around the world. Playing with a block diagram it is possible to produce an earthquake along a 1 meter long strike slip fault in a destroying all the man-made constructions close to it. A little movie introduces to volcanoes' world. Two small interactive exhibits allow visitors to understand the mechanism for the explosive and the effusive eruptions. Two other exciting interactive exhibits allow visitors to "create" two different eruptions: the explosive and the effusive ones. It is possible to get inside a volcano (a 2 meter high interactive exhibit) to attend an eruption from the magmatic chamber to the Earth surface. A big hall is completed dedicated to Italian volcanoes (Vesuvio, Campi Flegrei, Etna, Stromboli, Vulcano

This is especially true in the Levantine Basin following the recent widening of the Suez canal and the increase of the offshore deep wells for the exploitation of oil and gas. In order to select the optimal response measurements to assist the response agencies, oil spill models are used to provide predictions of the drift and weathering of the oil slicks. The establishment of the operational ocean forecasting systems at regional level, within the Copernicus Marine Environmental Monitoring Service and in association with the national downscaled ones, provided the background for the implementation of a multi model integrated oil spill prediction system for the entire Mediterranean to support the maritime safety in near real time. This implementation was carried out in the frame of the medess4ms.eu project, which is dedicated to the response agencies of the riparian countries and to

Outside of the Workshop, the participants were able to visit the historical Halls and Museum of the University, whose foundation dates back to the year 1361, and to enjoy a visit to the Certosa, a Carthusian monastery renowned for its exuberant architecture. Pavia welcomed the Conference participants by opening the doors of the Town Hall and offering a reception during which the Mayor's address underlined the importance of research and its applications in modern society. The successful organization and the smooth running of the Conference is due to many people and Institutions. We gratefully acknowledge the financial support of the Istituto Nazionale di Fisica Nucleare (INFN), the Department of Nuclear and Theoretical Physics and the University of Pavia, that made the Workshop possible, together with the contribution of our sponsors. The University also opened some rooms of the Chancellor's suite for the lunch and coffee breaks, and hosted the Conference Secretariat. We would like to express our deepest gratitude to the INFN and Department technical staff, who helped to prepare the Hall for the Conference and to provide computer services, and to the staff of the Theresian Library, who gave us access to the Room and organized a display of the many historical books from their vast and precious collections which are of interest to physicists. Above all, the success of the meeting is due to the participants who animated it, and in particular to the speakers for their dedicated work in preparing their excellent talks and in providing the write-ups, and to the conveners for their essential role in shaping an interesting and well balanced scientific program. Finally, we wish to thank the International Advisory Committee for their unfailing support and for offering us the opportunity to organize this Conference in Pavia.

    The Dawn spacecraft [1] is now approaching Ceres, the second of its targets. Ceres represents the key to understand some important points relative to the role of the protoplanet size and the water content in the evolution of these bodies. Ceres is thought to be differentiated, and hydrated minerals were proposed to exist on its surface [2,3,4]. Its low density [3] associated with the presence of transient water vapour, suggests a high content of ice inside the body and on its surface. Ceres seems to have been subject to differentiation and hydrothermal activity, and might host a liquid subsurface layer even today. Dawn is equipped with a Visible and InfraRed Mapping Spectrometer (VIR-MS) [5]. VIR-MS is an imaging spectrometer coupling high spectral and spatial resolution in the VIS (0.25-1 micron) and IR (0.95-5 micron) spectral ranges. The surface composition of Ceres is poorly understood through its nearly featureless visible spectrum. Its visible reflectance spectrum has a steep UV absorption edge that begins at a relatively short wavelength, around 0.4 micron, unlike many C-type asteroids where the UV drop-off begins around 0.6 to 0.7 micron[6]. The near-IR spectrum has a strong absorption band centered at about 3-micron. The absorption features in the 3-micron region were attributed to structural water in clay minerals [7,8] but could also be ammoniated clays [9]. [10] reported the discovery of carbonates and iron-rich clays from measurements of weak 3-micron features, and the results are consistent with the mid-IR spectra of clay minerals. On approach to Ceres, Dawn will obtain images and hyperspectral . VIR data, with resolution larger than Hubble images will reveal the first details of the Ceres' surface composition. Here we report about the first data obtained by VIR during its approach to Ceres.

    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.

    On May 27th 2010, the Italian astronomical community learned with concern that the National Institute for Astrophysics (INAF) was going to be suppressed, and that its employees were going to be transferred to the National Research Council (CNR). It was not clear if this applied to all employees (i.e. also to researchers hired on short-term contracts), and how this was going to happen in practice. In this letter, we give a brief historical overview of INAF and present a short chronicle of the ...

    The {sup 150}Nd is considered one of the most attractive candidate for searching neutrinoless double beta (0{nu}{beta}{beta}-) decay, thanks to its high Q-value (3.367 MeV), that makes the external background issue less significative respect to other isotopes, and favorable computed matrix elements. The isotopic abundance of this isotope in natural neodimium is only 5.6% and up to now, it has been investigated only in low mass experiments. The next step is to increase the sensitivity of the experiments using larger mass of neodymium (10 ton-1 kton). This could be possible with a Nd loaded liquid scintillator (LS). At the Gran Sasso National Laboratory (LNGS), a joint INFN (Istituto Nazionale di Fisica Nucleare) and INR (Institute for Nuclear Research of Moscow) working group has been carrying out since 2001 an R and D activity aiming to develop organic liquid scintillators (LS) doped with metals. The achieved know-how and the satisfactory results obtained both with In and Gd allowed to face the development and production of Nd doped LS. The development of metal doped LS is challenging because the metal has to be embedded in a proper organic system that makes it soluble in an organic solvent minimizing the impact of the metal-organic compound on the optical and scintillation properties of the LS. A further challenge in the case of Nd is the presence of absorption bands of this element in the optical region with a transparent region around 400 nm, which is about at the maximum of the scintillator emission spectrum. A 2.5 1 Nd loaded LS has been produced diluting an originally developed Nd-Carboxylic (Nd-CBX) salt in pseudocumene (PC), the solvent of the Borexino liquid scintillator. The measured light yield, at [Nd] = 6.5 g/1 and [PPO] = 1.5 g/1, is {approx} 75% of pure PC at the same fluor concentration ({approx} 10000 ph/MeV). The Nd doped LS has been tested in a 2 1 quartz cell (wrapped by VM2000 reflector film) having dimensions 5x5x100 cm{sup 3}. The light

    On October 22nd 2012, three and a half years after the earthquake that destroyed the city of L'Aquila (central Italy), killing more than 300 people and wounding about 1,500, a landmark judgment for the scientific research established the condemnation of six members of the Major Risks Committee of the Italian Government and a researcher of INGV (Istituto Nazionale di Geofisica e Vulcanologia), called to provide information about the evolution of the seismic sequence. The judge held that these Geoscientists were negligent during the meeting of 31st March 2009, convened to discuss the scientific aspects of the seismic risk of this area, affected by a long seismic sequence, also in the light of repeated warnings about the imminence of a strong earthquake, on the base of measurements of radon gas by an Italian independent technician, transmitted to the population by mass-media. Without going into the legal aspects of the criminal proceedings, this judgment strikes for the hardness of the condemnation to be paid by the scientists (six years of imprisonment, perpetual disqualification from public office and legal disqualification during the execution of the penalty, compensation for victims up to several hundred thousands of Euros). Some of them are scientists known worldwide for their proven skills, professionalism and experience. In conclusion, these scientists were found guilty of having contributed to the death of many people, because they have not communicated in an appropriate manner all available information on the seismic hazard and vulnerability of the area of L'Aquila. This judgment represents a watershed in the way of looking at the social role of geoscientists in the defense against natural hazards and their responsibility towards the people. But, in what does this responsibility consist of? It consists of the commitment to conduct an updated and reliable scientific research, which provides for a detailed analysis of the epistemic uncertainty for a more

  3. Developing seismogenic source models based on geologic fault data

    Science.gov (United States)

    Haller, Kathleen M.; Basili, Roberto

    2011-01-01

    Calculating seismic hazard usually requires input that includes seismicity associated with known faults, historical earthquake catalogs, geodesy, and models of ground shaking. This paper will address the input generally derived from geologic studies that augment the short historical catalog to predict ground shaking at time scales of tens, hundreds, or thousands of years (e.g., SSHAC 1997). A seismogenic source model, terminology we adopt here for a fault source model, includes explicit three-dimensional faults deemed capable of generating ground motions of engineering significance within a specified time frame of interest. In tectonically active regions of the world, such as near plate boundaries, multiple seismic cycles span a few hundred to a few thousand years. In contrast, in less active regions hundreds of kilometers from the nearest plate boundary, seismic cycles generally are thousands to tens of thousands of years long. Therefore, one should include sources having both longer recurrence intervals and possibly older times of most recent rupture in less active regions of the world rather than restricting the model to include only Holocene faults (i.e., those with evidence of large-magnitude earthquakes in the past 11,500 years) as is the practice in tectonically active regions with high deformation rates. During the past 15 years, our institutions independently developed databases to characterize seismogenic sources based on geologic data at a national scale. Our goal here is to compare the content of these two publicly available seismogenic source models compiled for the primary purpose of supporting seismic hazard calculations by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) and the U.S. Geological Survey (USGS); hereinafter we refer to the two seismogenic source models as INGV and USGS, respectively. This comparison is timely because new initiatives are emerging to characterize seismogenic sources at the continental scale (e.g., SHARE in the

    Italian primary schools participated with enthusiasm to the drawing competition 'I'm a scientist too! Science and scientists from the children point of view' organized by the Laboratorio di Didattica e Divulgazione Scientifica of Istituto Nazionale di Geofisica e Vulcanologia (INGV) in Rome, Italy. The best drawings were awarded and published in the 2011 school calendar. Children were asked to realize a drawing, choosing among three suggestions: 1) How do you imagine a scientist, and how do you imagine the daily activities of a researcher? 2) What invention do you consider the most important among all those you know? 3) What would you invent? The topic 'invention' (#3) was the most successful. In fact, among the collected 1,000 drawings, 400 drawings depict scientists, nearly 150 depict scientists with their inventions, and other 350 depict inventions alone. A classification scheme was designed in order to synthetically describe this set of images and analyze it. The Draw-A-Scientist scheme, known from literature, was maintained but modified in order to characterize both inventors and inventions. A preliminary analysis about scientists reveals a persistent gender stereotype, since most of depicted persons were male and nearly half of girls draw men scientists. The image of 'mad scientist' is still present but it is mainly related to men. Women scientists are drawn by girls; they are represented as young, not crazy, usually good-looking. There are no particular differences between boys and girls in assigning research fields to scientists. Women scientists are often depicted as assistants, but when alone they are self-confident enough to give their name to an invention or to aspire for Nobel Prize. In this work we present the preliminary analysis performed on drawings containing inventions. What do girls and boys 6 to 11 years old invent? Robots, helping in housekeeping or in doing homework; rockets, space vehicles and time machines, but also fictional machines and

    At present, there are no specific nationwide epidemiological studies representing the whole Italian population. This study is aimed at describing the epidemiological and economic burden that HCV will generate in the next few years in Italy. Furthermore, the impact that future anti-HCV treatments may have on the burden of disease was considered. This analysis was developed for the period 2012-2030 from the perspective of the Italian National Health Service (NHS). A published system dynamic model was adapted for Italy in order to quantify the HCV-infected population in terms of disease progression and the associated costs from 1950 to 2030. The model structure was based on transition probabilities reflecting the natural history of the disease. In order to estimate the efficacy of current anti-HCV treatment strategies for genotypes 1 and 4, the sustained virological response (SVR) rate in registration clinical trials for both boceprevir and telaprevir was estimated. It was assumed that the efficacy for patients treated with peginterferon + ribavirin was equal to the placebo arm of a randomized clinical trial (RCT) relating to boceprevir and telaprevir. For genotypes 2/3 patients it was assumed that treatment efficacy with dual therapy was equal to a SVR rate from the literature. According to the aim of this study, only direct health care costs (hospital admissions, drugs, treatment, and care of patients) incurred by the Italian NHS have been included in the model. Costs have been extrapolated using the published scientific literature available in Italy and actualized with the 2012 ISTAT (Istituto Nazionale di Statistica) Price Index system for monetary revaluation. Three different scenarios were assumed in order to evaluate the impact of future anti-HCV treatments on the burden of disease. Overall, in Italy, 1.2 million infected subjects were estimated in 2012. Of these, about 211,000 patients were diagnosed, while only about 11,800 subjects were actually being

    As regards the natural hazards, it grows more and more the awareness of the necessity of the transition from being exclusively prepared in the field of the disaster response, to the culture of prevention in tackling disasters. The culture of prevention is accomplished giving responsible and balanced information and continuous education to the citizens. Preparedness of people, knowledge on how to deal with natural disasters is a powerful resource for risk reduction. Geosciences researchers, working in the field of the natural hazards, more and more develop plans and focus energies not only devoted to scientific projects but also to disseminate the scientific results within the local population, the ultimate stakeholder, with the goal of diffusing basic geo-hazard knowledge of the territory studied. In the process of building a culture of prevention it is very important for the Geoscientists to be able to propose innovative projects of scientific teaching, for both schools and general population. The Science Teaching Laboratory (Didattica e Divulgazione Scientifica) of the Istituto Nazionale di Geofisica e Vulcanologia (INGV) have been engaged for years in projects of scientific dissemination. During the first edition of the Week of the Planet Earth in 2012 organized by Geoitalia (http://www.settimanaterra.org/), the INGV lab has proposed two original and innovative events for the general public combinig science and music. The first: "A musical journey among the Italian earthquakes", aims to raise the knowledge of the great historical earthquakes of the Italian peninsula, making an historical and musical journey through the seismic regions and using the local folk music to revive the popular traditions. This is a science communication event that combines scientific information with historical and musical expressions typical of the regions affected by earthquakes, and leads us to rediscover our "historical memory". The collective memory is fundamental to understand

    The Pollino Massif marks the transition from the Southern Appenninic to the Calabrian Arc. On the western side it is characterized by a moderately sized seismicity (about 9 M > 4 events in the last 50 years), well documented in the last 400 years. The moment tensor solutions available in this area yields, mainly, normal faults with coherent Southern Appeninic trend. This remains true also for the events that are localized on the calabrian side of Pollino, South of the massif. In most of the Sibari plane, seismic activity is very scarce, while it is again rather marked on its southeastern corner, both onshore and offshore. The above observations point to the perspective that the stress field of a vast portion of Northern Calabria still resembles that of the Southern Appenines. In this frame, it becomes important to investigate the offshore seismicity of the Sibari Gulf and the deformation pattern within the Sibari Plane. The latter might function as a hinge to transfer the deformation of the extensional fault system in the Pollino area to a different offshore fault system. Since return times of larger events might be very long, we need to investigate the true seismic potential of the offshore faults and to verify whether they are truly strike slip or if they could involve relevant thrust or normal components, that would add to the risk that of potentially associated tsunamis. Despite their importance in the understanding of the seismotectonic processes taking place in the Southern Appenninic - Calabrian Arc border and surrounding areas, the seismicity and the seismogenic volumes of the Sibari Gulf until now has not been well characterized due to the lack of offshore seismic stations. The seismicity of the Calabrian is monitored by the Italian National Seismic Network (INSN) managed by Istituto Nazionale di Geofisica e Vulcanologia and by the Calabrian Regional Seismic Network (CRSN) managed by the University of Calabria. Both the network comprise only on

    Questo progetto ha preso spunto da uno studio condotto da Giusy Zevolini e pubblicato nel 2003 sulla Rivista dell’Istituto Nazionale di Archeologia e Storia dell’Arte. Nell’articolo la studiosa proponeva un’ipotesi di ricomposizione di due opere scultoree in marmo, entrambe eseguite durante il XV secolo, una delle quali sicuramente dall’artista toscano Isaia da Pisa. Le due parti, in origine probabilmente inserite in un unico complesso scultoreo monumentale, all’interno della chiesa agostiniana della SS. Trinità di Viterbo, oggi sono conservate in due siti distinti del capoluogo del territorio della Tuscia.

    Virtual Reconstruction of the Tabernacolo of Isaia da Pisa for the Church of SS. Trinità in Viterbo

    This study is based upon a characteristic, Art History paper, published in 2003. Specifically it suggests a reconstruction hypotesis concerning two marble objects, created in the XV Century, which were supposed to belong to each other, in a monumental complex, inside the Augustinian Church of the SS. Trinità in Viterbo (Italy. In the article the iconography was rendered by simply stitching pictures together, losing the objects proportions, without any care given to the likely missing parts, and of course showing the image in 2D. Despite scholars mostly agreeing that the two marble artefacts were made by the same artist (Isaiada Pisa and that both belong to the same church, they are still notsure if the pieces are a unique structure. The virtual re-composition helps to enhance the visual perception of the whole construction, which is now available just in 2D flat images, and to understand how it originally would have looked. The two objects, today placed in different locations in the city of Viterbo, studied in this paper are: a marble tabernacle with Angels and Christ; a marble tympanum with a blessing by Christ. Both sculptures were acquired witha triangulation laser scanner in two different

    Since 2009 the Istituto Nazionale di Geofisica e Vulcanologia (INGV) participates to the European Researchers' Night, promoted by the European Commission, in the framework of Associazione Frascati Scienza (http://www.frascatiscienza.it/), with a program rich of events aimed at intriguingnand stimulating audiences of all ages about Earth Sciences, i.e., to make the general public aware on activities and roles of INGV researchers. For the September 27th Night, INGV contributed with a program in the INGV headquarters inspired by the INGV ScienzAperta Open Day held in April: guided tours, as well seminars held by researchers, exhibitions, educational games. We proposed two parallel programs: one devoted to earthquakes, including the visit to the INGV seismic surveillance room, seminars about Italian territory seismic hazard and exhibitions on Earthquakes and Volcanoes; the alternative program included the guided tour of the INGV laboratories (Aero-photogrammetry, Paleo-magnetism beside exhibition on geomagnetism, High Pressures and High Temperatures, Geochemistry, Restoration of historical instruments). In Frascati, we organized educational games, hands-on laboratories and a science theatre performance: "When the sky flashed red", as well as exhibitions at Museo Geofisico Rocca di Papa. A paper-based appreciation survey, compiled by visitors at INGV headquarter and by the scientific theatre's audiences, supplied our team with feedback, revealing some precious hints about users themselves, appreciation and margins of improvement, both in organization and in content. People of all ages and professions came. For example, a father asked specific paths for children, with even more appropriate language. A boy (aged 11) found the visit to the labs "interesting but a bit boring". It was suggested to prepare specific hand-outs for each visit, and certificates of participation for students. A girl, 9 years old, wrote that such event makes her closer to science world. The

    Different forms of Civic Service are present in Europe. The National Civic Service (SCN) of Italy started, with a law, as an alternative to military service in 2001. It was conceived as an opportunity to people from 18 to 28 years, the volunteers, who intend to grow in social, civic, cultural and professional dimensions while performing experiences of social solidarity, national and international cooperation, protection and preservation of national heritage. Each accredited organization, which hosts SCN projects, signs up an ethical charter, regulating relationships between volunteers and the hosting organization. Summarizing, the organization must be aware 1)of putting into effect a law aimed to involve young generations in homeland defense with non violent means through services of social utility; 2) that the Civic Service wants young people to spend one year of their life in a critical phase in which they reach the responsibilities of adults; 3) that adopted working method is learning by doing, working with tutors having to increase skills and exploit the full potential of volunteers; 4) of recognizing the volunteers' right to work to reach the project's objectives, and not only for the benefits of the hosting organization; 5) that volunteers should work with well defined procedures, clear since the beginning; 6) of requiring from volunteers their full commitment to learn and responsibly participate to project's activities as well as to fully express and increase their expertise, skills and personal resources. Ethical implications emerged during an ongoing Earth Sciences education project funded by SCN and involving young volunteers at Istituto Nazionale di Geofisica e Vulcanologia (INGV). According to SCN's ethical charter, in this case the challenge is to welcome a group of young people in a public research organization, and to integrate them in the limited time lapse of one year. The European Charter for Researchers came as a valuable help. Its principles

Then, as usual, the program of the meeting consisted of general talks and more specialized contributions, which covered five main topics: i) From nuclear forces to nuclear structure; ii) Exploring nuclear structure toward the drip line; iii) Role of the shell model in the study of exotic nuclei; iv) Nuclear structure aspects outside the shell model; and v) Special topics. The main conclusions were drawn in two keynote talks given by Amand Faessler and Franco Iachello. The Conference had about 90 participants from some 20 countries [please see the list of participants]. This is well in line with the tradition of these meetings, as is the fact that more than 50% of the present participants attended one or more of the previous Seminars. We received 58 manuscripts out of the 73 invited papers and contributions presented at the Seminar. All of these have been peer reviewed and are collected in this volume. We would like to thank all the colleagues who have acted as referees to assess the suitability of the various articles for publication in the Journal of Physics: Conference Series. We are confident that the high quality of both invited and contributed papers contained in these Proceedings will be appreciated by the nuclear physics community. We gratefully acknowledge the members of the Advisory Committee for their valuable cooperation in preparing the scientific program as well as the financial support of the Istituto Nazionale di Fisica Nucleare, the University of Naples Federico II, and the Dipartimento di Fisica who helped make the Seminar possible.

    2010-05-01

    The SDLS was created in April 1991 under the auspices of the Scientific Committee on Antarctic Research to provide open access to Antarctic multichannel seismic-reflection data (MCS) for use in cooperative research projects. The SDLS operates under the mandates of the Antarctic Treaty System, by which all institutions that collect MCS data in Antarctica must submit their MCS data to the SDLS. The SDLS has library branches worldwide at which researchers may view and study the MCS data. MCS data are submitted to the SDLS within 4 years of collection and remain in the library under SDLS guidelines until 8 years after collection. Thereafter, the data go to World Data Centers or equivalents for unrestricted use. The SDLS offers a clearing house, based at Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (OGS) where data are processed when needed and georeferenced, so that the end user can be provided with usable, although basic, post-stack seismic sections. Re-processing of data is beyond the scope of the SDLS, so that if a researcher is interested in reviewing pre-stack data he/she must resort to the data owner. So far 228,000 km of seismic data have been made public in all sectors of the Antarctic region. To augment the concept of physical repositories where data can be accessed by researchers travelling to one of the branches or from where data could be copied to digital media and sent to users, in 2003 it was decided to develop a web interface where data could be searched for and accessed directly. At that moment no previous non-commercial experience was available in this data field, so that the system was designed from scratch. Several technologies were introduced, tested, and after a period of use, reviewed and tuned. Particular attention was devoted to the seismic data viewing facility, which was tailored to the needs of a community with specific practices and legacies. Seismic data are sensitive data that are very important for the E&P industry, so

    SN2011ht has been described both as a true supernova (SN) and as an impostor. In this paper, we conclude that it does not match some basic expectations for a core-collapse event. We discuss SN2011ht's spectral evolution from a hot dense wind to a cool dense wind, followed by the post-plateau appearance of a faster low density wind during a rapid decline in luminosity. We identify a slow dense wind expanding at only 500-600 km s-1, present throughout the eruption. A faster wind speed V ~ 900 km s-1 occurred in a second phase of the outburst. There is no direct or significant evidence for any flow speed above 1000 km s-1 the broad asymmetric wings of Balmer emission lines in the hot wind phase were due to Thomson scattering, not bulk motion. We estimate a mass-loss rate of order 0.05 M ⊙ yr-1 during the hot dense wind phase of the event. The same calculations present difficulties for a hypothetical unseen SN blast wave. There is no evidence that the kinetic energy greatly exceeded the luminous energy, roughly 3 × 1049 erg so the radiative plus kinetic energy was small compared to a typical SN. We suggest that SN2011ht may have been a giant eruption driven by super-Eddington radiation pressure, perhaps beginning a few months before the discovery. A strongly non-spherical SN might also account for the data at the cost of more free parameters.

    Radon is a radioactive noble gas present in all rocks of the Earth. It's used by the scientific community as a tracer of natural phenomena related to outgassing from the soil along faults, fractures and crustal discontinuity. Recently, radon has also been used on active volcanoes such as Etna, both as a precursor of volcanic phenomena as well as in the study of the dynamics of faults. The Istituto Nazionale di Geofisica e Vulcanologia (INGV) performs discrete and continuous measurements of radon from soil at Etna since 2002. First studies concerned measurements of radon and thoron emissions from soil carried out on the E and SW flanks of Etna, in zones characterized by the presence of numerous seismogenic and aseismic faults. The statistical treatment of the geochemical data allowed recognizing anomaly thresholds, producing distribution maps that highlighted a significant spatial correlation between soil gas anomalies and tectonic lineaments. These studies confirmed that mapping the distribution of radon and thoron in soil gas can reveal hidden faults buried by recent soil cover. INGV permanent radon monitoring network was installed in July 2005. First results were obtained during the July 2006 eruption. The radon signal recorded at Torre del Filosofo (TdF, ~2950 m asl) was compared with volcanic tremor and thermal radiance data. The onset of explosive activity and a lava fountaining episode were preceded by some hours with increases in radon activity and more gradual increases in volcanic tremor. After 2006, Etna produced dozens of paroxysmal episodes from a new vent opened on the eastern flank of the Southeast Crater (summit area), that have built up a new, huge pyroclastic cone. In many cases we observed increase in radon activity some hours before the eruptive events. These observations suggest that radon emissions from the TdF zone are sensitive to the local geodynamic pressure induced by magma dynamics in the conduit systems. Other promising results were

    In the last three years the Calabria-Lucania border area is affected by an intense seismic activity generated by the activation of geological structures which be seat of clusters of microearthquakes, with energy release sufficient to be felt and to generate alarm and bother. Besides to the historical memory of the inhabitants of Mormanno (the town most affected of macroseismic effects) there are some historical documents that indicate the occurrence of a similar seismic crisis in 1888. A more recent seismic sequence, the first monitored by seismic instruments, occurred in 1973-1974. In the last case, the activity started in early 2010 and is still ongoing. The two shocks of ML = 4.3 and 5.0 and the the very long time duration differs this crisis from the previous ones. Given this background, in 1981 was installed at Mormanno a seismic station (MMN) belonging to Regional Seismic Network of the University of Calabria (RSRC), now also a station of the Italian National Seismic Network of the Istituto Nazionale di Geofisica Vulcanolgia (INSN-INGV). This seismic station made it possible to follow the evolution of seismicity in this area and in particular the progressive increase in seismic activity started in 2010. Since 2010, some 3D stand-alone, was installed by the University of Calabria. Further stations of INGV were installed in November 2011 after a sharp increase of the energy release and subsequently by the INGV and the GeoForschungsZentrum (Potsdam) after the main shock of the whole sequence. Seismic networks are powerful tools for understanding active tectonic processes in a monitored seismically active region. However, the optimal monitoring of a seismic region requires the assessment of the seismic network capabilities to identify seismogenic areas that are not adequately covered and to quantify measures that will allow the network improvement. In this paper we examine in detail the evolution and the strengthening of the RSRC in the last years analyzing the

    The October 30, 2016 (06:40 UTC) Mw 6.5 earthquake occurred about 28 km NW of Amatrice village as the result of upper crust normal faulting on a nearly 30 km-long, NW-SE oriented, SW dipping fault system in the Central Apennines. This earthquake is the strongest Italian seismic event since the 1980 Mw 6.9 Irpinia earthquake. The Mw 6.5 event was the largest shock of a seismic sequence, which began on August 24 with a Mw 6.0 earthquake and also included a Mw 5.9 earthquake on October 26, about 9 and 35 km NW of Amatrice village, respectively. Field surveys of coseismic geological effects at the surface started within hours of the mainshock and were carried out by several national and international teams of earth scientists (about 120 people) from different research institutions and universities coordinated by the EMERGEO Working Group of the Istituto Nazionale di Geofisica e Vulcanologia. This collaborative effort was focused on the detailed recognition and mapping of: 1) the total extent of the October 30 coseismic surface ruptures, 2) their geometric and kinematic characteristics, 3) the coseismic displacement distribution along the activated fault system, including subsidiary and antithetic ruptures. The huge amount of collected data (more than 8000 observation points of several types of coseismic effects at the surface) were stored, managed and shared using a specifically designed spreadsheet to populate a georeferenced database. More comprehensive mapping of the details and extent of surface rupture was facilitated by Structure-from-Motion photogrammetry surveys by means of several helicopter flights. An almost continuous alignment of ruptures about 30 km long, N150/160 striking, mainly SW side down was observed along the already known active Mt. Vettore - Mt. Bove fault system. The mapped ruptures occasionally overlapped those of the August 24 Mw 6.0 and October 26 Mw 5.9 shocks. The coincidence between the observed surface ruptures and the trace of active

    Purpose: To study EBT3 GafChromic film in low-energy protons, and for comparison purposes, in a reference 60 Co beam in order to use it as a calibrated dosimetry system in the proton irradiation facility under construction within the framework of the Oncological Therapy with Protons (TOP)-Intensity Modulated Proton Linear Accelerator for RadioTherapy (IMPLART) Project at ENEA-Frascati, Italy. Methods: EBT3 film samples were irradiated at the Istituto Nazionale di Fisica Nucleare—Laboratori Nazionali di Legnaro, Italy, with a 5 MeV proton beam generated by a 7 MV Van de Graaff CN accelerator. The nominal dose rates used were 2.1 Gy/min and 40 Gy/min. The delivered dose was determined by measuring the particle fluence and the energy spectrum in air with silicon surface barrier detector monitors. A preliminary study of the EBT3 film beam quality dependence in low-energy protons was conducted by passively degrading the beam energy. EBT3 films were also irradiated at ENEA-National Institute of Ionizing Radiation Metrology with gamma radiation produced by a 60 Co source characterized by an absorbed dose to water rate of 0.26 Gy/min as measured by a calibrated Farmer type ionization chamber. EBT3 film calibration curves were determined by means of a set of 40 film pieces irradiated to various doses ranging from 0.5 Gy to 30 Gy absorbed dose to water. An EPSON Expression 11000XL color scanner in transmission mode was used for film analysis. Scanner response stability, intrafilm uniformity, and interfilm reproducibility were verified. Optical absorption spectra measurements were performed on unirradiated and irradiated EBT3 films to choose the most sensitive color channel to the dose range used. Results: EBT3 GafChromic films show an under response up to about 33% for low-energy protons with respect to 60 Co gamma radiation, which is consistent with the linear energy transfer dependence already observed with higher energy protons, and a negligible dose-rate dependence in

    Patient-reported outcomes may help inform treatment choice in advanced/metastatic renal cell carcinoma (RCC), particularly between approved targeted therapies with similar efficacy. This double-blind crossover study evaluated patient preference for pazopanib or sunitinib and the influence of health-related quality of life (HRQoL) and safety factors on their stated preference. Patients with metastatic renal cell carcinoma were randomly assigned to pazopanib 800mg per day for 10 weeks, a 2-week washout, and then sunitinib 50mg per day (4 weeks on, 2 weeks off, 4weeks on) for 10 weeks, or the reverse sequence. The primary end point, patient preference for a specific treatment, was assessed by questionnaire at the end of the two treatment periods. Other end points and analyses included reasons for preference, physician preference, safety, and HRQoL. Of 169 randomly assigned patients, 114 met the following prespecified modified intent-to-treat criteria for the primary analysis: exposure to both treatments, no disease progression before cross over, and completion of the preference questionnaire. Significantly more patients preferred pazopanib (70%) over sunitinib (22%); 8% expressed no preference (P<.001). All preplanned sensitivity analyses, including the intent-to-treat population, statistically favored pazopanib. Less fatigue and better overall quality of life were the main reasons for preferring pazopanib, with less diarrhea being the most cited reason for preferring sunitinib. Physicians also preferred pazopanib (61%) over sunitinib (22%); 17% expressed no preference. Adverse events were consistent with each drug׳s known profile. Pazopanib was superior to sunitinib in HRQoL measures evaluating fatigue, hand/foot soreness, and mouth/throat soreness. This innovative crossover trial demonstrated a significant patient preference for pazopanib over sunitinib, with HRQoL and safety as key influencing factors. Copyright © 2016 Elsevier Inc.
