    In the Space Station Processing Facility (SSPF), work continues on the U.S. Lab module, Destiny, which is scheduled to be launched on Space Shuttle Endeavour in early 2000. It will become the centerpiece of scientific research on the International Space Station. Destiny shares space in the SSPF with the Shuttle Radar Topography Mission (SRTM) and Leonardo, the Multipurpose Logistics Module (MPLM) built by the Agenzia Spaziale Italiana (ASI). The SRTM is targeted for launch on mission STS-99 in September 1999. Leonardo is scheduled to launch on mission STS- 102 in June 2000.

    “Galileo Galilei” (GG) is a small satellite designed to fly in low Earth orbit with the goal of testing the Equivalence Principle—which is at the basis of the General Theory of Relativity—to 1 part in 1017. If successful, it would improve current laboratory results by 4 orders of magnitude. A confirmation would strongly constrain theories; proof of violation is believed to lead to a scientific revolution. The experiment design allows it to be carried out at ambient temperature inside a small 1-axis stabilized satellite (250 kg total mass). GG is under investigation at Phase A-2 level by ASI (Agenzia Spaziale Italiana) at Thales Alenia Space in Torino, while a laboratory prototype (known as GGG) is operational at INFN laboratories in Pisa, supported by INFN (Istituto Nazionale di fisica Nucleare) and ASI. A final study report will be published in 2009.

  3. On the Behavior of the Frequency Break Between Fluid and Kinetic Regimes in Solar Wind Fluctuations During Radial Expansion

    NASA Astrophysics Data System (ADS)

    Bruno, Roberto; Trenchi, Lorenzo

    2014-05-01

    We investigate the radial dependence of the spectral break located at the border between fluid and kinetic regimes during the wind expansion between 0.42 and 5.3 AU. We exploited radial alignments between MESSENGER and WIND for the inner heliosphere and between WIND and ULYSSES for the outer heliosphere. We found that this spectral break moves to lower and lower frequencies as heliocentric distance increases, following a power law dependence. Our results would support conclusions from previous studies which require that a cyclotron-resonant dissipation mechanism must participate into the spectral energy cascade together with other possible kinetic noncyclotron-resonant mechanisms.

    RIASSUNTO. Lo scopo del presente studio è quello di esplorare le proprietà psicometriche di uno strumento di misurazione dell'affetto, la Scala di Esperienze Positive e Negative (SPANE), all'interno di una popolazione italiana. Gli esiti dell'analisi fattoriale confermativa comprovano l'attesa struttura a due fattori, sentimenti positivi e negativi. Le correlazioni con altre dimensioni (per es., ansia, depressione, affetto, aspettative future) confermano i risultati ottenuti con le precedenti versioni della scala: affetto negativo, ansia, depressione e aspettative future negative correlano positivamente con la subscala di esperienze negative e negativamente con la subscala di esperienze positive dello SPANE. In conclusione, i risultati del nostro studio dimostrano che la versione italiana dello SPANE presenta caratteristiche psicometriche simili a quelle mostrate dalla versione orginale e da successive validazioni dello strumento in altre lingue. La scala presenta, inoltre, affidabilità e validità fattoriale. Lo SPANE è un indice utile dal punto di vista clinico che può fornire informazioni rilevanti circa l'esperienza emotiva e il benessere della persona. Nonostante ulteriori studi siano necessari per confermare le caratteristiche psicometriche della scala, la presente validazione della versione italiana dello SPANE può contribuire ad ampliare la ricerca nell'ambito del benessere in una popolazione Italiana.

    2007-01-01

    The Author comes recently across the proceedings volume of the forgotten XVIII Congress of the ''Società Italiana di Cardiologia'' held in Trieste on May 1956. The proceedings focus on the ''cardiopatia renale'', i.e. the heart lesion observed in Kidney disease, namely in acute glomerulonephritis. Later ''Cardiopatia renale'' changes into ''uremic cardiomyopathy'' but the terms seem uncorrect as they do not include the cardiac derangement in early stages of nephropathies. The diction ''cardiomyopaty'' in uremic seems more complete. The topic becomes very ''hot'' and the kidney- heart scientific culture grows more and more and culminates with the ''Cardionephrology'' term coined in 1991 at Assisi Meeting and then wide spread all over Europe.

    The Agenzia Spaziale Italiana (ASI) is currently under negotiation with the Bendix Field Engineering Corporation (BFEC) of the Allied Signal Aerospace Company (ASAC) to build a state-of-the-art laser ranging observatory for the Centro di Geodesia Spaziale, in Matera, Italy. The contract calls for the delivery of a system based on a 1.5 meter afocal Cassegrain astronomical quality telescope with multiple ports to support a variety of experiments for the future, with primary emphasis on laser ranging. Three focal planes, viz. Cassegrain, Coude, and Nasmyth will be available for these experiments. The open telescope system will be protected from dust and turbulence using a specialized dome which will be part of the building facilities to be provided by ASI. The fixed observatory facility will be partitioned into four areas for locating the following: laser, transmit/receive optics, telescope/dome enclosure, and the operations console. The optical tables and mount rest on a common concrete pad for added mechanical stability. Provisions will be in place for minimizing the effects of EMI, for obtaining maximum cleanliness for high power laser and transmit optics, and for providing an ergonomic environment fitting to a state-of-the-art multipurpose laboratory. The system is currently designed to be highly modular and adaptable for scaling or changes in technology. It is conceived to be a highly automated system with superior performance specifications to any currently operational system. Provisions are also made to adapt and accommodate changes that are of significance during the course of design and integration.

    Purpose: We analyzed whether the prognosis can differ among Wilms tumors (WT) labeled as Stage III according to currently adopted classification systems. Methods and Materials: Patients with nonanaplastic Stage III WT consecutively registered in two Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) trials (CNR-92, TW-2003) were the subjects in the present analysis. The steady mainstay of therapy was primary nephrectomy, followed by three-drug chemotherapy with vincristine, dactinomycin, doxorubicin, and abdominal radiotherapy (RT). Results: Ninety-nine WT patients met the criteria for classification as Stage III according to a revised version of the National Wilms Tumor Study-3 staging system (51 patients in CNR-92, 48 patients in TW-2003). Regional lymph nodes (LN) were not biopsied in 16 patients. After a median follow-up of 66 months, the 4-year disease-free survival (DFS) and overall survival (OS) rates were 85% {+-} 4% and 92% {+-} 3%, respectively, for the whole group. For 38 children with positive LN, the 4-year DFS rate was 73% {+-} 7%, as opposed to 98% {+-} 2% for the 45 children with Stage III WT according to the other criteria but with negative biopsied LN (p = 0.001). The subgroup with the worst prognosis consisted of children more than 2 years old with positive LN (DFS 67% {+-} 8%). A delay between surgery and RT > 30 days had an adverse impact on the abdominal tumor relapse rate. Conclusions: This study provides further evidence that Stage III tumors with LN metastases might be distinguished from WTs meeting the other criteria for classification as Stage III. The worse outcome of the former may warrant a prospective study on the effects of intensified therapy. A subclassification of Stage III tumors is discussed.

    Between May 1980 and April 1987, 49 children with acute lymphoblastic leukemia (ALL) in isolated testicular and first leukemia relapse (ITR) were enrolled in the Associazione Italiana Ematologia ed Oncologia Pediatrica (AIEOP) multicenter study REC80-ITR. According to the Rome Workshop criteria, 77% were at standard and 23% at high initial prognostic risk. In 33% of the cases, ITR occurred during first treatment. The REC80-ITR protocol consisted of an induction phase regimen of vincristine (VCR), cytarabine (ARA-C), methotrexate (MTX), and asparaginase (L-asp), and bilateral testicular irradiation, and CNS prophylaxis with intrathecal MTX and a maintenance phase with a multidrug rotating regimen. Total treatment duration was 30 months. The median time of observation after ITR was 51 months. The Kaplan-Meier estimates of survival and disease-free survival (DFS) at 4 years were 67.7% and 41%, respectively. Patients who had an ITR on therapy or within the first off-therapy year showed the poorest outcome. The DFS at 3 years was 20%, 47.6%, and 100%, respectively, for children who had an ITR on treatment (n = 16), within the first year of treatment withdrawal (n = 22), or later (n = 10) (P = .001). Patients with an asymptomatic occult testicular infiltrate at treatment discontinuation had a very unfavorable prognosis. Eighty-one percent of second relapses involved the bone marrow. In our experience, children presenting an early ITR (ie, within 6 months of treatment withdrawal) need a very aggressive treatment because of the high probability of an underlying systemic disease. On the other hand, patients with a late ITR seem to have a truly local recurrence and can apparently be cured by standard protocols, as shown in protocol REC80-ITR.

    The targets of the ESA CORNERSTONE mission to Mercury "BepiColombo" are concerned with both planetary and magnetospheric physics and to test some aspects of the general relativity. A payload devoted to a set of experiments named radio science is located within one of the three proposed modules, the Mercury Planetary Orbiter (MPO). In particular, a high sensitivity accelerometer ( a min<10 -9√g/ Hz in the range 10 -4- 10 -1 Hz) will measure the inertial acceleration acting on the MPO. Such data, together with tracking data are used to evaluate the purely gravitational trajectory of the MPO, transforming it to a virtual drag-free satellite system. The ISA accelerometer, considered for this mission, is a well-studied instrument developed at the Istituto di Fisica dello Spazio Interplanetario (IFSI), with the financial support of the Agenzia Spaziale Italiana (ASI). A prototype of such an instrument was constructed, matching the requirements of the radio science experiment. Results of the study concerning the use of ISA in the BepiColombo mission are reported here, particular care being devoted to the description of the instrument and to its sensitivity and thermal stabilisation.

  12. On the Estimate of Frequency Break and Spectral Index at Ion Scales for Interplanetary Magnetic Field Fluctuations

    2014-12-01

    We exploited radial alignments between MESSENGER and WIND spacecraft to study: 1) the radial dependence of the spectral break located at the border between fluid and kinetic regimes; 2) the dependence, if any, of the spectral slope, around the frequency break, on the type of wind, either fast or slow.We found that this spectral break moves to lower and lower frequencies as heliocentric distance increases, following a power-law dependence. Moreover, we found evidence that a cyclotron-resonant dissipation mechanism must participate into the spectral energy cascade together with other possible kinetic noncyclotron-resonant mechanisms.On the other hand, the spectral slope shows a large variability between -3.75 and -1.75 with an average value around -2.8 and a robust tendency for this parameter to be steeper within the trailing edge of high speed streams and to be flatter within the subsequent slower wind, following a gradual transition between these two states. The value of the spectral index seems to depend firmly on the power associated to the fluctuations within the inertial range, higher the power steeper the slope.

    The Cassini mission is a joint venture between NASA, European Space Agency (ESA), and Agenzia Spaziale Italiana (ASI). A major interface is between the NASA/Jet Propulsion Laboratory (JPL) provided Orbiter and the ESA provided Atmospheric Probe. The Orbiter is designed to orbit the planet Saturn, while the Probe will descend into the atmosphere and impact the surface of Titan. After years of study and scientific meetings between NASA, JPL, and ESA, a Memorandum of Understanding was signed between NASA and ESA on 17 December 1990. Project teams were formed at JPL and ESA and work began on the interface definition and integration of the Probe onto the Orbiter. Unique challenges were presented due to the fact that this was the first such atmospheric probe designed and developed in Europe, the complicated mechanical and electrical interface between the Probe and the Orbiter, and the nine hour time difference between JPL and ESA. As with the Galileo mission to Jupiter, the Orbiter provides an environmentally acceptable vehicle for the Probe during the long cruise phase, a communication link to Earth for periodic Probe checkouts during this cruise phase, a stable and accurately pointed platform for Probe separation, and a relay link to Earth for the actual Probe mission descent into the Titan atmosphere. Management and technical interchange tools were developed to address these challenges. The Probe design and its interface with the Orbiter are the result of this effort.

    John Powell (left) and Jim Nail (second from right) of McDonnell Douglas Space and Defense Systems prepare the satellite element of the Tethered Satellite System-1R (TSS-1R) for integration with its support unit in the Operations and Checkout (O&C) Building. The TSS-1R is one of two primary payloads scheduled to fly aboard the Orbiter Columbia during the STS-75 mission in early 1996. The TSS program is a joint venture between NASA and the Agenzia Spaziale Italiana, or Italian Space Agency. The 'R' designation indicates a reflight. The TSS-1 flew aboard Atlantis during the STS-46 mission in July 1992 and achieved only a partial success when its tether reel mechanism became jammed after only approximately 840 feet of the 12-mile-long tether had been unwound as the satellite rose from its cradle in the orbiter's payload bay. Once deployed to the 12-mile height on the STS-75 mission, the satellite will be used to validate theories that such a system could possibly be used in the future to generate electrical power to power orbital systems, raise and lower spacecraft, study atmospheric conditions at several different heights and for many other applications.

    Ten years ago, on 14 January 2005, the Huygens Probe parachuted down to the surface of Titan, Saturn's largest moon. Huygens is part of the international Cassini/Huygens mission, a joint endeavor of NASA, the European Space Agency, and Agenzia Spaziale Italiana. Cassini/Huygens, comprising the NASA-provided Saturn Orbiter and the ESA-provided Huygens probe, was launched in October 1997. It arrived at Saturn in early July 2004. Huygens was released on the 3rd orbit around Saturn. It made measurements during the hypersonic entry, the descent, and for more than one hour on the surface. Unique in situ characterization of the atmosphere along the entry and descent trajectory and of the surface at the landing site was provided, revealing that many Earth-like processes were at work on Titan, a very fascinating methane world. Huygens observations also allowed inferring the ice crust thickness, hence an estimation of the depth of the icy crust/liquid water ocean interface. Huygens measurements are also used as ground-truth of the measurements made by the orbiter during Titan flybys. In this presentation, after a brief review of the major mission milestones, Huygens achievements are discussed in the context of the progress made in our understanding of Titan during the Cassini/Huygens mission. Lessons learned for the future in situ exploration of Titan are addressed. * Most of this work was performed while at ESA/ESTEC, Noordwijk, The Netherlands

    Congenital and acquired neutropenia are rare disorders whose frequency in pediatric age may be underestimated due to remarkable differences in definition or misdiagnosed because of the lack of common practice guidelines. Neutropenia Committee of the Marrow Failure Syndrome Group (MFSG) of the AIEOP (Associazione Italiana Emato-Oncologia Pediatrica) elaborated this document following design and methodology formerly approved by the AIEOP board. The panel of experts reviewed the literature on the topic and participated in a conference producing a document which includes a classification of neutropenia and a comprehensive guideline on diagnosis of neutropenia.

    The purpose of this study was to assess the role of ABMT in children with ALL who are in 2nd CR after an early isolated CNS relapse. All children experiencing an isolated CNS relapse at 10 AIEOP centers (Associazione Italiana Emato-Oncologia Pediatrica) from 1986 to 1992 were eligible for this study. The series included 69 patients who relapsed within 3 years from diagnosis: 19 underwent ABMT, nine patients underwent ALLO-BMT from an HLA-identical sibling, and 41 received conventional chemotherapy (CHEMO). Statistical analysis was performed using a Cox's regression model, adjusting for the waiting time before transplantation and prognostic factors. The 5 years DFS was 56.3% (s.e. 12.3) for patients in the ABMT group. This compared favorably with the poor result (12.6% (s.e. 5.9)) seen in the CHEMO group. The risk of failures was reduced by one-third in the ABMT group as compared to the CHEMO group in the multivariate analysis (P < 0.01). In the ALLO group four out of nine patients were in CCR 4-5 years post-transplant. This study suggests that ABMT may also represent a valuable therapeutic choice for patients lacking a matched familiar donor in 2nd CR after an early isolated CNS relapse.

    Between 1976 and 1986, 2,093 children with ALL were enrolled in three consecutive generations of trials conducted by the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP). A 50% event-free survival at 5 years was achieved overall in this population, approximately accounting for more than 50% of the entire childhood ALL population in Italy. Participation in the group protocols increased from the original seven founding centers to the current 37 institutions. Results in the standard population (non-T immunophenotype, non-FAB L3, and less than 50,000 white blood cells (WBC/ml) were considerably better with more recent, more aggressive protocols. The two major results in this population (N = 540) were a relatively low incidence (8% at 5 years) of central nervous system (CNS) relapse in the "good"-risk population (less than 10,000 WBC, ages 3-6 years, and FAB L1), without the use of cranial irradiation, and a projected 4-year disease-free interval for bone-marrow relapse of 80% in the "average"-risk group, where a three-drug reinduction program was adopted after consolidation. Overall, the event-free survival of the most recent generation (protocol 82, median follow-up time of 38 months) is 66% at 4 years (95% confidence limits [CL] 61-71). Based on these 10 years of experience, the general strategy of the group for the 90s is outlined and discussed.

  1. Proposed noncryogenic, nondrag-free test of the equivalence principle in space

    Ever since Galileo scientists have known that all bodies fall with the same acceleration regardless of their mass and composition. Known as the Universality of Free Fall, this is the most direct experimental evidence of the Weak Equivalence Principle, a founding pillar of General Relativity according to which the gravitational (passive) mass mg and the inertial mass mi are always in the same positive ratio in all test bodies. A space experiment offers two main advantages: a signal about a factor of a thousand bigger than on Earth and the absence of weight. A new space mission named GALILEO GALILEI (GG) has been proposed (Nobili et al., 1995 [J. Astronautical Sciences, 43, 219]; GALILEO GALILEI (GG), PRE PHASE A REPORT, ASI (Agenzia Spaziale Italiana), September 1996) aimed at testing the weak Equivalence Principle (EP) to 1 part in 10 17 in a rapidly spinning (5 Hz) drag-free spacecraft at room temperature, the most recent ground experiments having reached the level of 10 -12 (Adelberger et al., 1990 [PhRvD, 42, 3267]; Su et al., 1994 [PhRvD, 50, 3614]). Here we present a nondrag-free version of GG which could reach a sensitivity of 1 part in 10 16. The main feature of GG is that, similarly to the most recent ground experiments, the expected (low frequency) signal is modulated at higher frequency by spinning the system, in this case by rotating the test bodies (in the shape of hollow cylinders) around their symmetry axes, the signal being in the perpendicular plane. They are mechanically suspended inside the spacecraft and have very low frequencies of natural oscillation (due to the weakness of the springs that can be used because of weightlessness) so as to allow self-centering of the axes; vibrational noise around the spin/signal frequency is attenuated by means of mechanical suspensions. The signal of an EP violation would appear at the spin frequency as a relative ( differential) displacement of the test masses perpendicularly to the spin axis, and be detected

    The Cassini-Huygens mission has greatly enhanced our understanding of the Saturn system. Fundamental discoveries have altered our views of Saturn, its retinue of icy moons including Titan, the dynamic rings, and the system’s complex magnetosphere. Cassini has orbited Saturn for 10 years, delivering the Huygens probe to its Titan landing in 2005. It is now three years into its 7-year Solstice mission, returning science in a previously unobserved seasonal phase. As it watches the approach of northern summer, long-dark regions throughout the system become sunlit, allowing Cassini’s science instruments to probe as-yet unsolved mysteries. Key Cassini-Huygens discoveries include icy jets of material streaming from tiny Enceladus’ south pole, lakes of liquid hydrocarbons and methane rain on giant Titan, three-dimensional structures in Saturn’s rings, and curtain-like aurorae flickering over Saturn’s poles. The Huygens probe sent back amazing images of Titan’s surface, and made detailed measurements of the atmospheric composition, structure and winds. Key Cassini-Huygens science highlights will be presented. The Solstice Mission continues to provide new science as Cassini observes seasonal and temporal changes, and addresses new questions that have arisen during the mission thus far. The mission’s grand finale occurs in 2017, with 22 inclined orbits between the innermost D ring and the upper portions of Saturn’s atmosphere, enabling unique gravity and magnetic field measurements of the planet, unprecedented determination of the ring mass, some of the highest resolution measurements of the rings and Saturn, and in situ observations in a completely new region around the planet.

    A seven-year journey to the ringed planet Saturn begins with the liftoff of a Titan IVB/Centaur carrying the Cassini orbiter and its attached Huygens probe. Launch occurred at 4:43 a.m. EDT, October 15, 1997 from Launch Complex 40 on Cape Canaveral Air Station. After a 2.2-billion mile journey that will include two swing-bys of Venus and one of Earth to gain additional velocity, the two-storey tall spacecraft will arrive at Saturn in July 2004. The orbiter will circle the planet for four years, its complement of 12 scientific instruments gathering data about Saturn's atmosphere, rings and magnetosphere and conducting closeup observations of the Saturnian moons. Huygens, with a separate suite of six science instruments, will separate from Cassini to fly on a ballistic trajectory toward Titan, the only celestial body besides Earth to have an atmosphere rich in nitrogen. Scientists are eager to study further this chemical similarity in hopes of learning more about the origins of our own planet Earth. Huygens will provide the first direct sampling of Titan's atmospheric chemistry and the first detailed photographs of its surface. The Cassini mission is an international effort involving NASA, the European Space Agency (ESA) and the Italian Space Agency, Agenzia Spaziale Italiana (ASI). The Jet Propulsion Laboratory manages the U.S. contribution to the mission for NASA's Office of Space Science, Washington, DC.

    GIADA (Grain Impact Analyzer and Dust Accumulator) is an in-situ instrument mounted onboard Rosetta monitoring the dust environment of comet 67P/Churyumov-Gerasimenko. GIADA is composed of 3 sub-systems: 1) the Grain Detection System, based on particle detection through light scattering; 2) the Impact Sensor, giving momentum measurement; 3) the Micro-Balances System, constituted of 5 quartz crystal microbalances, giving cumulative deposited dust. The combination of the measurements performed by these 3 subsystems provides: the number, the mass, the momentum and the speed distribution of dust particles emitted from the comet nucleus. We will present the coma dust environment as observed by GIADA during the perihelion phase of the Rosetta space mission. Despite the large distance from the nucleus, more than 200 km, GIADA was able to detect temporal and spatial variation of dust density distribution. Specific high dust spatial density sectors of the coma have been identified and their evolution during the perihelion phase was studied. Acknowledgements. GIADA was built by a consortium led by the Univ. Napoli "Parthenope" & INAF- Oss. Astr. Capodimonte, IT, in collaboration with the Inst. de Astrofisica de Andalucia, ES, Selex-ES s.p.a. and SENER.

    Data acquired on April 13, 1994 and on October 4, 1994 from the X-band Synthetic Aperture Radar on board the space shuttle Endeavour were used to generate interferometric fringes, which were overlaid on the X-SAR image of Kilauea. The volcano is centered in this image at 19.58 degrees north latitude and 155.55 degrees west longitude. The image covers about 9 kilometers by 13 kilometers (5.6 miles by 8 miles). The X-band fringes correspond clearly to the expected topographic image. The yellow line indicates the area below which was used for the three-dimensional image using altitude lines. The yellow rectangular frame fences the area for the final topographic image. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory. X-SAR was developed by the Dornier and Alenia Spazio companies for the German space agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian space agency, Agenzia Spaziale Italiana (ASI), with the Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.V.(DLR), the major partner in science, operations and data processing of X-SAR. The Instituto Ricerca Elettromagnetismo Componenti Elettronici (IRECE) at the University of Naples was a partner in interferometry analysis.

The foreseen launch of new space platforms as the Sentinel satellites, providing good monitoring frequencies and free worldwide access to data is expected to increase the number of scientific and commercial activities exploiting EO data. In the sector of natural hazards the EO data have already demonstrated to be indispensable for the generation of information products for the prevention, and emergency management phases. In particular, the Italian Space Agency has promoted and funded, together with INGV, the development of dedicated infrastructures for the generation of advanced information products supporting different phases of the seismic and volcanic risk management cycles. These products were based mainly on SAR data from the COSMO-SkyMed 4-satellite constellation, and on optical data from commercial and scientific platforms, integrated with data from ground monitoring networks. During the last few years, such infrastructures have been tested under operational conditions and the products distributed to the Italian Civil Protection authority for validation and assessment. Here, with reference to the earthquake emergency management, we will present the infrastructure, the rapid mapping information products and some examples of activities during the latest seismic crises.

  10. Methodology and results of a space station education pilot programme in the primary school

    NASA Astrophysics Data System (ADS)

    Mirra, G.; Mirra, C.

    Potential users of the Space Station Freedom are now still in the Primary School. Subject studies 1 have shown that a robust familiarization programme has to be developed in order to increase public awareness on the microgravity environment and its capabilities to perform unique science. At the same time, several surveys 2 have demonstrated that elementary school students are showing the greatest interest and enthusiasm in space related activities among all school students. With these boundary conditions, a pilot programme, aimed at verifying the capabilities of young primary school pupils (aged between 10 and 12) in understanding why one performs research in space, has been conceived. In order to overcome the lack of space training of school teachers, an expert in space operations joined a group of elementary teachers to activate this program: merging the necessary didactic and technical capabilities. Consequently, the aim of the program becomes two folded: •generate critical thinking and problem solving capacities as well as inventiveness in children making them aware on the use of space to improve life on Earth. •identify the key issues for the definition of a robust space utilization educational programme. The programme has been managed by MARS Center. the Italian User Support Center for the Space Station utilization, and the institute "Speranzas" in the nearby of Naples, Italy. MARS Center, in particular, is responsible towards the national agency ASI, Agenzia Spaziale Italiana, of the execution of the promotional activity towards all the possible target groups: young students are among these groups. This programme started in late 1992 and is currently ongoing. The objective of this paper is to provide a description of the methodology and the reasons of such a programme with a snapshot on the preliminary results and future trends. Means used as supporting tools, such as films, posters and role plays are herein depicted as well as statistics on the pupils

    The management of congenital and acquired neutropenias presents some differences according to the type of the disease. Treatment with recombinant human granulocyte-colony stimulating factor (G-CSF) is not standardized and scanty data are available on the best schedule to apply. The frequency and the type of longitudinal controls in patients affected with neutropenias are not usually discussed in the literature. The Neutropenia Committee of the Marrow Failure Syndrome Group (MFSG) of the Associazione Italiana di Emato-Oncologia Pediatrica (AIEOP) elaborated this document following design and methodology formerly approved by the AIEOP board. The panel of experts reviewed the literature on the topic and participated in a conference producing a document that includes recommendations on neutropenia treatment and timing of follow-up.

    1997-01-01

    Jet Propulsion Laboratory (JPL) workers examine the Huygens probe after removal from the Cassini spacecraft in the Payload Hazardous Servicing Facility (PHSF) at KSC. The spacecraft was returned to the PHSF after damage to the thermal insulation was discovered inside Huygens from an abnormally high flow of conditioned air. The damage required technicians to inspect the inside of the probe, repair the insulation, and clean the instruments. After returning from the PHSF to Launch Pad 40 at Cape Canaveral Air Station, Cassini/Huygens launched successfully in October 1997, and reached Saturn in July of 2004. Scientific instruments carried aboard the Cassini orbiter will study Saturn's atmosphere, magnetic field, rings, and several moons, while the Huygens probe will separate and land on the surface of Titan, Saturn's largest moon. The Cassini-Huygens mission owes its name to the Dutch astronomer Christiaan Huygens and Italian astronomer Giovanni Domenico Cassini. Both had spectacular careers as observers of the heavens, which included important discoveries about Saturn and its satellites. Huygens (1629-1695) discovered Saturn's largest moon, Titan, in 1655 and in 1656 described the shape and phase changes of Saturn's rings. Cassini (1625-1712) was the first to observe four of Saturn's moons, Iapetus, Rhea, Tethys, and Dione, in the 1670s and 1680s. He also, in 1675, discovered the gap in Saturn's rings, now called the Cassini Division, and proposed that the rings were formed from many tiny particles. Cassini-Huygens is a joint mission of NASA, the European Space Agency (ESA), and the Italian Space Agency, Agenzia Spaziale Italiana (ASI). JPL is managing the Cassini project for NASA. The mission was proposed in November 1982 by a group of European and American scientists from the European Science Foundation and the National Academy of Sciences. The Solar System Exploration Committee of the NASA Advisory Council endorsed the idea in April 1983, and NASA and ESA began a

GIADA is composed of 3 sub-systems: 1) the Grain Detection System, based on particle detection through light scattering; 2) the Impact Sensor, measuring particle momentum; 3) the Micro-Balances System, constituted of 5 quartz crystal microbalances, providing cumulated dust from different directions. From the combination of the measurements performed by the three subsystems we retrieve: the number, the mass, the momentum, the speed of individual dust particles and the cumulative dust flux emitted from the comet nucleus. We will present the coma dust environment as observed by GIADA during the pre-landing and escort phases of the Rosetta space mission. GIADA was able to detect temporal and spatial variation of dust density distribution and to disentangle different types of impacting dust particles. Specific high dust spatial density sectors of the coma have been identified and their evolution with respect to the heliocentric distance was studied. From August 2014 to December 2015, i.e. inbound, at and outbound perihelion, Rosetta performed different trajectories around the nucleus and flybys with different close approach distances, different coordinates of the sub-spacecraft point and different observing geometry (phase angle), allowed GIADA to characterize the dust environment within the 67P/C-G coma and its temporal variation.

    This X-band image of the volcano Kilauea was taken on October 4, 1994, by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar. The area shown is about 9 kilometers by 13 kilometers (5.5 miles by 8 miles) and is centered at about 19.58 degrees north latitude and 155.55 degrees west longitude. This image and a similar image taken during the first flight of the radar instrument on April 13, 1994 were combined to produce the topographic information by means of an interferometric process. This is a process by which radar data acquired on different passes of the space shuttle is overlaid to obtain elevation information. Three additional images are provided showing an overlay of radar data with interferometric fringes; a three-dimensional image based on altitude lines; and, finally, a topographic view of the region. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory.

North is toward the top left corner of the image. The Kaitak Airport runway on Kowloon Peninsula (center right of image) was built on reclaimed land and extends almost 3 kilometers (nearly 2 miles) into Victoria Harbor. To the south of the harbor lies the island of Hong Kong. The bright areas around the harbor are the major residential and business districts. Housing more than six million residents, Hong Kong is the most densely populated area in the world. The large number of objects visible in the harbor and surrounding waters are a variety of sea-going vessels, anchored in one of the busiest seaports in the Far East.

  14. Comparison of independent integrated water vapour estimates from GPS and sun photometer measurements and a meteorological model

    Measurements using the Global Positioning System (GPS) are affected by the so-called tropospheric delay. Of this, the so-called wet delay is related mainly to the amount of water vapour along the path of the GPS signal through the troposphere. Precise knowledge of the abundance of water vapour, in space and time, is important for meteorology, both in forecasting and now-casting as well as in climate studies. Both because water vapour is the predecessor of precipitation, which is a forecast product, and because a very significant fraction of the energy released to the atmosphere comes from latent heat via water vapour. Despite the high variability of water vapour compared to other meteorological fields, like pressure and wind, water vapour observations are scarce; wherefore additional measurements of water vapour are expected to benefit meteorology. Water vapour is crucial for the development of the small scale, but sometimes very severe,precipitation events which are often seen at mid latitudes, and which are very hard to predict. In this work a comparison between radiometric (sun photometer) and GPS integrated water vapour (IWV) is presented. A sun photometer has been installed at the ENEA (Ente per le Nuove tecnologie, l'Energia e l'Ambiente) base of Lampedusa Island. The sun photometer is quite close (less then 4 km) to an ASI (Agenzia Spaziale Italiana) GPS permanent receiver. In Venezia an ASI GPS permanent receiver is collocated with another sun photometer. Both sun photometers are installed as part of the AERONET (AErosol and RObotic NETwork) program. A long record of sun photometric measurements, GPS data, and meteorological data is available for the Venezia site. A shorter record (summer period of the year 2000) is available for the station at Lampedusa. The comparison among the three different methods for water vapour delay estimation is presented. We find that the GPS and sun photometric data are better correlated (S.D. about 10 mm for the wet delay

    The Mission X: Train Like an Astronaut Challenge was developed in 2011 to encourage proper exercise and nutrition at an early age by teaching young people to live and eat like space explorers. The strong correlation between an unhealthy childhood diet and adolescent fitness, and the onset of chronic diseases as an adult is the catalyst for Mission X. Mission X is dedicated to assisting people on a global scale to live healthier lifestyles and learn about human space exploration. The Mission X: Train Like an Astronaut 2015 (MX15) International Challenge hosted almost 40,000 children on 800 teams, 28 countries affiliated with 12 space agencies. The MX15 website included 17 languages. MX15, the fifth annual international fitness challenges sponsored by the NASA Human Research Program worked with the European Space Agency and other space agencies from around the world. In comparison to MX14, MX15 expanded to include four additional new countries, increased the number of students by approximately 68% and the number of teams by 29%. Chile' and South Korea participated in the new fall Astro Charlie Walk Around the Earth Challenge. Pre-challenge training materials were made more readily available from the website. South Korea completed a prospective assessment of the usability of the MX content for improving health and fitness in 212 preschool children and their families. Mission X is fortunate to have the support of the NASA, ESA and JAXA astronaut corps. In MX15, they participated in the opening and closing events as well as while on-board the International Space Station. Italian Astronaut Samantha Cristoretti participated as the MX15 Astronaut Ambassador for health and fitness providing the opening video and other videos from ISS. United Kingdom Astronaut Tim Peake and US Astronaut Kate Rubins have agreed to be the MX Ambassadors for 2016 and 2017 respectively.

    GIADA (Grain Impact Analyzer and Dust Accumulator) flying on-board Rosetta is devoted to study the cometary dust environment of 67P/Churiumov-Gerasimenko. GIADA is composed of 3 sub-systems: the GDS (Grain Detection System), based on grain detection through light scattering; an IS (Impact Sensor), giving momentum measurement detecting the impact on a sensed plate connected with 5 piezoelectric sensors; the MBS (MicroBalances System), constituted of 5 Quartz Crystal Microbalances (QCMs), giving cumulative deposited dust mass by measuring the variations of the sensors' frequency. The combination of the measurements performed by these 3 subsystems provides: the number, the mass, the momentum and the velocity distribution of dust grains emitted from the cometary nucleus.No prior in situ dust dynamical measurements at these close distances from the nucleus and starting from such large heliocentric distances are available up to date. We present here the first results obtained from the beginning of the Rosetta scientific phase. We will report dust grains early detection at about 800 km from the nucleus in August 2014 and the following measurements that allowed us characterizing the 67P/C-G dust environment at distances less than 100 km from the nucleus and single grains dynamical properties.

    GIADA (Grain Impact Analyzer and Dust Accumulator) is an in-situ instrument devoted to measure the dynamical properties of the dust grains emitted by the comet. An Extended Calibration activity using the GIADA Flight Spare Model has been carried out taking into account the knowledge gained through the analyses of IDPs and cometary samples returned from comet 81P/Wild 2. GIADA consists of three measurement subsystems: Grain Detection System, an optical device measuring the optical cross-section for individual dust; Impact Sensor an aluminum plate connected to 5 piezo-sensors measuring the momentum of impacting single dust grains; Micro Balance System measuring the cumulative deposition in time of dust grains smaller than 10 μm. The results of the analyses on data acquired with the GIADA PFM and the comparison with calibration data acquired during the pre-launch campaign allowed us to improve GIADA performances and capabilities. We will report the results of the following main activities: a) definition of a correlation between the 2 GIADA Models (PFM housed in laboratory and In-Flight Model on-board ROSETTA); b) characterization of the sub-systems performances (signal elaboration, sensitivities, space environment effects); c) new calibration measurements and related curves by means of the PFM model using realistic cometary dust analogues.

    (21)ESA-ESAC, Camino Bajo del Castillo, s/n., Urb. Villafranca del Castillo, 28692 Villanueva de la Cañada, Madrid, Spagna The MicroBalance System (MBS) is one of the three measurement subsystems of GIADA, the Grain Impact Analyzer and Dust Accumulator on board the Rosetta/ESA spacecraft (S/C). It consists of five Quartz Crystal Microbalances (QCMs) in roughly orthogonal directions providing the cumulative dust flux of grains smaller than 10 microns. The MBS is continuously monitoring comet 67P/CG since the beginning of May 2014. During the first 4 months of measurements, before the insertion of the S/C in the bound orbit phase, there were no evidences of dust accumulation on the QCMs. Starting from the beginning of October, three out of five QCMs measured an increase of the deposited dust. The measured fluxes show, as expected, a strong anisotropy. In particular, the dust flux appears to be much higher from the Sun direction with respect to the comet direction.

    The molecular approach for the analysis of leukemia associated chromosomal translocations has led to the identification of prognostic relevant subgroups. In pediatric acute lymphoblastic leukemia (ALL), the most common translocations, t(9;22) and t(4;11), have been associated with a poorer clinical outcome. Recently the TEL gene at chromosome 12p13 and the AML1 gene at chromosome 21q22 were found to be involved in the translocation t(12;21)(p13;q22). By conventional cytogenetics, however, this chromosomal abnormality is barely detectable and occurs in less than 0.05% of childhood ALL. To investigate the frequency of the molecular equivalent of the t(12;21), the TEL/AML1 gene fusion, we have undertaken a prospective screening in the running German Berlin-Frankfurt-Münster (BFM) and Italian Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) multicenter ALL therapy trials. We have analyzed 334 unselected cases of pediatric ALL patients consecutively referred over a period of 5 and 9 months, respectively. The overall incidence of the t(12;21) in pediatric ALL is 18.9%. The 63 cases positive for the TEL/AML1 chimeric products ranged in age between 1 and 12 years, and all but one showed CD10 and pre-B immunophenotype. Interestingly, one case displayed a pre-pre-B immunophenotype. Among the B-lineage subgroup, the t(12;21) occurs in 22.0% of the cases. Fifteen of 61 (24.6%) cases coexpressed at least two myeloid antigens (CD13, CD33, or CDw65) in more than 20% of the gated blast cells. DNA index was available for 59 of the 63 TEL/AML1 positive cases; a hyperdiploid DNA content (> or = 1.16) was detected in only four patients, being nonhyperdiploid in the remaining 55. Based on this prospective analysis, we retrospectively evaluated the impact of TEL/AML1 in prognosis by identifying the subset of B-lineage ALL children enrolled in the closed German ALL-BFM-90 and Italian ALL-AIEOP-91 protocols who had sufficient material for analysis.

    Ground penetrating radar on board a satellite has entered the field of planetary geology. Two radars enable subsurface observations of Mars. In 2003, ESA launched the Mars Express equipped with MARSIS, a low frequency radar which was able to detect only the base of the ice caps. Since December 2006, the Shallow Radar (SHARAD) of Agenzia Spaziale Italiana (ASI) on board the NASA Mars Reconnaissance Orbiter (MRO) is active in orbit around Mars. The SHARAD radar covers the frequency band between 15 and 25 MHz. The vertical resolution is about 15 m in free space. The horizontal resolution is 300-1000 m along track and 1500-8000 m across track. The radar penetrates the subsurface of Mars up to 2 km deep, and is capable of detecting multiple reflections in the ice caps of Mars. Considering the scarcity of planetary data relative to terrestrial data, it is essential to combine all available types of data of an area of interest. Up to now SHARAD data has only been interpreted separately as 2D radargrams. The Geological Survey of the Netherlands has decades of experience in interpreting 2D and 3D seismic data of the Dutch subsurface, especially for the 3D interpretation of reservoir characteristics of the deeper subsurface. In this abstract we present a methodology which can be used for 3D interpretation of SHARAD data combined with surface data using state-of-the art seismic software applied in the oil and gas industry. We selected a region that would be most suitable to demonstrate 3D interpretation. The Titania Lobe of the North Polar ice cap was selected based on the abundancy of radar data and the complexity of the ice lobe. SHARAD data is released to the scientific community via the Planetary Data System. It includes ‘Reduced Data Records' (RDR) data, a binary format which contains the radargram. First the binary radargram data and corresponding coordinates were combined and converted to the commonly used seismic seg-y format. Second, we used the reservoir

    Cassini/Huygens, a flagship mission to explore the rings, atmosphere, magnetic field, and moons that make up the Saturn system, is a joint endeavor of NASA, the European Space Agency, and Agenzia Spaziale Italiana. Comprising two spacecraft - a Saturn orbiter built by NASA and a Titan entry/descent probe built by the European Space Agency - Cassini/Huygens was launched in October 1997 and arrived at Saturn in 2004. The Huygens probe parachuted to the surface of Titan in January 2005. During the descent, six science instruments provided measurements of Titan's atmosphere, clouds, and winds, and photographed Titan's surface. It was recognized early in the Huygens program that to correctly interpret and correlate results from the probe science experiments and to provide a reference set of data for ground truth calibration of the Cassini orbiter remote sensing observations, an accurate reconstruction of the probe entry and descent trajectory and surface landing location would be necessary. The Huygens Descent Trajectory Working Group (DTWG) was chartered in 1996 as a subgroup of the Huygens Science Working Team. With membership comprising representatives from all the probe engineering and instrument teams as well as representatives of industry and the Cassini and Huygens Project Scientists, the DTWG presented an organizational framework within which instrument data was shared, the entry and descent trajectory reconstruction implemented, and the trajectory reconstruction efficiently disseminated. The primary goal of the Descent Trajectory Working Group was to develop retrieval methodologies for the probe descent trajectory reconstruction from the entry interface altitude of 1270 km to the surface using navigation data, and engineering and science data acquired by the instruments on the Huygens Probe, and to provide a reconstruction of the Huygens probe trajectory from entry to the surface of Titan that is maximally consistent with all available engineering and science

    data on grain speed and its optical cross section. The IS grain momentum measurement, when combined with the GDS detection time, provides a direct measurement of grain speed and mass. These combined measurements characterize single grain dust dynamics in the coma of 67P/CG. The first grain was detected on 1 August 2014 at 814 km from the comet nucleus. Between then and 13 Septem-ber 2014 GIADA detected 35 grains ranging in mass from ~ 5 x 10-10 to 8 x 10-8 kg. Including complementary data from the OSIRIS narrow angle camera, the dust mass loss was calculated over an additional three orders of magni-tude in mass, extending the ejected dust grain sizes up to 2 cm. Combined with data from the MIRO and the ROSINA instruments onboard Rosetta we find a dust/gas mass ratio of 4 +/- 2 averaged over the sunlit nucleus sur-face. The dust to gas ratio may change as the comet approaches closer to the Sun. Acknowledgments: GIADA was built by a consortium led by the Univ. Napoli "Parthenope" & INAF- Oss. Astr.

    cover and alpine glaciers are critical to the radiation and water balances. SIR-C/X-SAR is a powerful tool because it is sensitive to most snowpack conditions and is less influenced by weather conditions than other remote sensing instruments, such as Landsat. In parallel with the operational SIR-C data processing, an experimental effort is being conducted to test SAR data processing using the Jet Propulsion Laboratory's massively parallel supercomputing facility, centered around the Cray Research T3D. These experiments will assess the abilities of large supercomputers to produce high throughput SAR processing in preparation for upcoming data-intensive SAR missions.

    . Oceanographers believe this process forms most of the oceans' deep water. Sea ice covering all of the southern oceans, including the Weddell Sea, typically reaches its most northerly extent in about September. As periods of daylight become gradually longer in the Southern Hemisphere, ice formation stops and the ice edge retreats southward. By February, most of the sea ice surrounding Antarctica disappears. Imaging radar is extremely useful for studying the polar regions because of the long periods of darkness and extensive cloud cover. The multiple frequencies of the SIR-C/X-SAR instruments allow further study into ways of improving the separation of the various thickness ranges of sea ice, which are vital to understanding the heat balance in the ice, ocean and atmospheric system.

    The Italian Scientific Associations of Cardiologists and Cardiovascular Pathologists have produced this consensus document on the diagnostic role of endomyocardial biopsy (EMB) in terms of techniques, analysis and reporting. The document is intended for clinical cardiologists, hemodynamic experts, electrophysiologists, surgical pathologists, and cardiac surgeons. It has three main aims: a) to collocate EMB in the context of currently available tools for diagnosis of heart diseases; b) to provide recommendations for rational implementation; c) to outline key characteristics (standards) for Italian cardiology and surgical pathology centers that perform and analyze EMB. A general lack of prospective, controlled studies addressing EMB prohibited the use of traditional evidence-based recommendations that rely on classes of available evidence. Thus, it was agreed that three key points should be taken into account: a) the specific pathology to be diagnosed (or excluded); b) the existence of any alternative, non-invasive diagnostic techniques; c) the overall consequences of reaching a definite diagnosis on patients' clinical management. Accordingly, we propose recommendations for EMB based on the following levels of diagnostic value: level 1: no alternative method exists to reach a definite diagnosis that can have obvious consequences for clinical management; level 2a: no alternative method exists to reach a definite diagnosis; however, the implications for clinical management are uncertain; level 2b: no alternative method exists to reach a definite diagnosis; however, the diagnosis would not influence clinical management; level 3: an alternative method exists to reach a definite diagnosis. The second part of the document proposes current protocols for the preparation, analysis and reporting of EMB in the context of each main pathologic entity. Particular attention is given to tissue characterization and implementation of molecular tests.

  4. Doing without codeine: why and what are the alternatives?

    PubMed Central

    2014-01-01

    Codeine is a mild opioid widely used as an analgesic in various age groups, including various pediatric settings. It is a prodrug that owes its analgesic effect almost entirely to the principal metabolite: morphine. The genetic polymorphisms can contribute to making the pharmacokinetics of codeine hard to predict and this it is particularly important in the pediatric population because infants and children have greater susceptibility to the side-effects of morphine. In recent years there have been several reports in the literature on the risks relating to the use of codeine. In August 2012, the American Food and Drugs Administration began to revise its recommendations for the safe use of codeine and in February 2013, established that codeine should not be used for postoperative pain control in children undergoing adenoidectomy and/or tonsillectomy and did restrict the use of this drug in the pediatric population. In June 2013, the European Medicine Agency opted the same decision. In July 2013, the Agenzia Italiana del Farmaco prohibit the use of medicines containing codeine for patients under 12 years old and recommended a limited use of the drug, in many other situations. Complying with these recommendations naturally means changing habits and treatment strategies well established in pediatric practice, but other drugs, tools and techniques available enable us to continue to assure an adequate pain control in pediatric patients, irrespective of their age and situation. The article proposes same alternatives of pain control drugs. PMID:24517264

    A total of 2192 children with acute lymphoblastic leukaemia who had reached cessation of therapy in complete remission were followed for a median time of 52 months after treatment suspension. Of the 485 relapses observed, 62.3% occurred in the first year off therapy and 68.9% involved the bone marrow. Eight relapses were reported more than 5 years (62-143 months) after treatment withdrawal. Males fared worse than females consistently, experiencing 1.5 times more relapses (P < 0.0001). Thirteen patients died in continuous complete remission, 5 because of non-neoplastic central nervous system complications. There were 11 second solid malignancies, 8 of them in the central nervous system; 9 subjects presented an haematopoietic malignancy after ALL. The projected event-free survival at 8 years is 73%. Twenty-two of the 171 young adults (age > 20 years) were married and 16 have had 21 healthy children. Twenty-four per cent of patients experienced an unfavourable event. Relapses accounted for 93% of failures. Central nervous system late effects and second malignancies were the major causes of non-leukaemic morbidity and mortality.

    Purpose: The protocols of the 1990s omitted or delayed irradiation, using upfront chemotherapy to spare the youngest children with ependymoma the sequelae of radiotherapy (RT). We treated 41 children under the age of 3 years with intracranial ependymoma between 1994 and 2003. Patients and Methods: After surgery, chemotherapy was given as follows: regimen I with four blocks of vincristine, high-dose methotrexate 5 g/m{sup 2}, and cyclophosphamide 1.5 g/m{sup 2} alternating with cisplatin 90 mg/m{sup 2} plus VP16 450 mg/m{sup 2} for 14 months; subsequently, regimen II was used: VEC (VCR, VP16 300 mg/m{sup 2}, and cyclophosphamide 3 g/m{sup 2}) for 6 months. Radiotherapy was planned for residual tumor after the completion of chemotherapy or for progression. Results: We treated 23 boys and 18 girls who were a median 22 months old; 14 were given regimen I, 27 were given regimen II; 22 underwent complete resection, 19 had residual tumor. Ependymoma was Grade 2 in 25 patients and Grade 3 in 16; tumors were infratentorial in 37 patients and supratentorial in 4. One child had intracranial metastases; 29 had progressed locally after a median 9 months. Event-free survival was 26% at 3 and 5 years and 23% at 8 years. One child died of sepsis, and another developed a glioblastoma 72 months after RT. Progression-free survival was 27% at 3, 5, and 8 years, and overall survival was 48%, 37%, and 28% at 3, 5, and 8 years, respectively. Of the 13 survivors, 6 never received RT; their intellectual outcome did not differ significantly in those children than in those without RT. Conclusions: Our results confirm poor rates of event-free survival and overall survival for up-front chemotherapy in infant ependymoma. No better neurocognitive outcome was demonstrated in the few survivors who never received RT.

    Background The duration of antibiotic treatment of exacerbations of COPD (ECOPD) is controversial. Serum procalcitonin (PCT) is a biomarker of bacterial infection used to identify the cause of ECOPD. Methods and Findings We investigated whether a PCT-guided plan would allow a shorter duration of antibiotic treatment in patients with severe ECOPD. For this multicenter, randomized, non-inferiority trial, we enrolled 184 patients hospitalized with ECOPD from 18 hospitals in Italy. Patients were assigned to receive antibiotics for 10 days (standard group) or for either 3 or 10 days (PCT group). The primary outcome was the rate of ECOPD at 6 months. Having planned to recruit 400 patients, we randomized only 183: 93 in the PCT group and 90 in the standard group. Thus, the completed study was underpowered. The ECOPD rate at 6 months between PCT-guided and standard antibiotic treatment was not significant (% difference, 4.04; 90% confidence interval [CI], −7.23 to 15.31), but the CI included the non-inferiority margin of 15. In the PCT-guided group, about 50% of patients were treated for 3 days, and there was no difference in primary or secondary outcomes compared to patients treated for 10 days. Conclusions Although the primary and secondary clinical outcomes were no different for patients treated for 3 or 10 days in the PCT group, the conclusion that antibiotics can be safely stopped after 3 days in patients with low serum PCT cannot be substantiated statistically. Thus, the results of this study are inconclusive regarding the noninferiority of the PCT-guided plan compared to the standard antibiotic treatment. The study was funded by Agenzia Italiana del Farmaco (AIFA-FARM58J2XH). Clinical trial registered with www.clinicaltrials.gov (NCT01125098).

    Performance of the Tethered Satellite System (TSS) Deployer during the STS-46 mission (July and August 1992) is analyzed in terms of hardware operation at the component and system level. Although only a limited deployment of the satellite was achieved (256 meters vs 20 kilometers planned), the mission served to verify the basic capability of the Deployer to release, control and retrieve a tethered satellite. - Deployer operational flexibility that was demonstrated during the flight is also addressed. Martin Marietta was the prime contractor for the development of the Deployer, under management of the NASA George C. Marshall Space Flight Center (MSFC). The satellite was provided by Alenia, Torino, Italy under contract to the Agencia Spaziale Italiana (ASI). Proper operation of the avionics components and the majority of mechanisms was observed during the flight. System operations driven by control laws for the deployment and retrieval of the satellite were also successful for the limited deployment distance. Anomalies included separation problems for one of the two umbilical connectors between the Deployer and satellite, tether jamming (at initial Satellite fly-away and at a deployment distance of 224 meters), and a mechanical interference which prevented tether deployment beyond 256 meters. The Deployer was used in several off-nominal conditions to respond to these anomalies, which ultimately enabled a successful satellite retrieval and preservation of hardware integrity for a future re-flight. The paper begins with an introduction defining the significance of the TSS-1 mission. The body of the paper is divided into four major sections: (1) Description of Deployer System and Components, (2) Deployer Components/Systems Demonstrating Successful Operation, (3) Hardware Anomalies and Operational Responses, and (4) Design Modifications for the TSS-1R Re-flight Mission. Conclusions from the TSS-1 mission, including lessons learned are presented at the end of the

    Just one year ago the Italian Society of Pathology (S.I.A.P.) created a Study Group which included members of the most active Italian hematopathology teams. Prof. Pasquale Calapso was asked to chair the Group and Prof. Stefano Pileri to take care of secretarial duties. The aim of the Group is to spread hematopathologic knowledge among young pathologists and to promote activities that can contribute to updating Italian pathologists on topics of both speculative and diagnostic interest. The first Workshop of the S.I.A.P. Hematopathology Group was held at the Palazzo dei Congressi in Bologna, November 20, 1993. About 150 pathologists from all over Italy took part in the meeting, which consisted of two sections devoted to: a) discussion of the boundaries between Hodgkin's disease and non-Hodgkin's lymphomas, and b) a case seminar illustrating the impact of immunohistochemistry in the diagnosis of bone-marrow biopsy. The first section included 5 presentations and a Round Table chaired by Prof. Luciano Fiore-Donati. Below, the contributors to this section summarize the content of their presentations, which were aimed at answering specific questions the Organizers had put to them.

    The introduction of new technologies for diagnosis and screening programs led to an increasing rate of early detection of colorectal cancer. This, associated with the evolution of endoscopic techniques of local excision, led to the assessment of new strategies to reduce morbidity related to treatment, especially for early rectal cancer (ERC). Nevertheless, the definition of ERC and its staging and treatment algorithm are still under debate. The Italian Society of Colorectal Surgery developed practice guidelines to provide recommendations on the diagnosis, staging and treatment of ERC. A systematic review on the topic was performed by a multidisciplinary group of experts selected based on their clinical and scientific expertise in endoscopy, endoscopic ultrasound, magnetic resonance and surgery, with the aid of an external international audit.

    Early colon cancer (ECC) has been defined as a carcinoma with invasion limited to the submucosa regardless of lymph node status and according to the Royal College of Pathologists as TNM stage T1 NX M0. As the potential risk of lymph node metastasis ranges from 6 to 17% and the preoperative assessment of lymph node metastasis is not reliable, the management of ECC is still controversial, varying from endoscopic to radical resection. A meeting on recent advances on the management of colorectal polyps endorsed by the Italian Society of Colorectal Surgery (SICCR) took place in April 2014, in Genoa (Italy). Based on this material the SICCR decided to issue guidelines updating the evidence and to write a position statement paper in order to define the diagnostic and therapeutic strategy for ECC treatment in context of the Italian healthcare system.

The results indicated that among most of the doctors who completed the questionnaire the basic principles of pain treatment in cancer patients are largely understood. Oral morphine emerged as the most commonly used opioid (60%) and controlled-release morphine as the preferred preparation. Non-steroidal anti-inflammatory drugs were the most commonly used minor analgesics. Fear of side effects and restrictive prescribing regulations emerged as the most important barrier against adequate pain management. The survey emphasised the need for continued efforts in implementing specific educational programming for improvement in cancer pain management. PMID:9349310

    Pearson syndrome (PS) is a very rare and often fatal multisystemic mitochondrial disorder involving the liver, kidney, pancreas, and hematopoietic and central nervous system. It is characterized principally by a transfusion-dependent anemia that usually improves over time, a tendency to develop severe infections, and a high mortality rate. We describe a group of 11 PS patients diagnosed in Italy in the period 1993-2014. The analysis of this reasonably sized cohort of patients contributes to the clinical profile of the disease and highlights a rough incidence of 1 case/million newborns. Furthermore, it seems that some biochemical parameters like increased serum alanine and urinary fumaric acid can help to address an early diagnosis.

    One hundred and forty-seven patients aged < 55 years with advanced acute lymphoblastic leukaemia (ALL) were enrolled in an Italian cooperative study (ALL R-87). This protocol consists of an induction phase with idarubicin (IDA) plus intermediate-dose cytarabine (IDARA-C), followed by a consolidation phase and bone marrow transplant (BMT). Complete remission (CR) was achieved in 97/147 patients (66%) with a CR rate of 77% in children versus 51% in adults (P < 0.01). 48 responders (50%) underwent BMT. Probability of event-free survival (EFS +/- SE) was 10.2 +/- 3.1% at 56 months. EFS was 14.3 +/- 4.51% at 56 months for children versus 3.8 +/- 3.41% at 37 months for adults (P < 0.0001). Among patients treated in first relapse, EFS was 14.2 +/-7.79% for patients with CR > 18 months verus 6.6 +/- 3.17% for those with CR < 18 months (P < 0.0001). Projected disease-free survival (DFS +/- SE) was 15.4 +/- 4.61% at 55 months for all responders and 43.3 +/- 14.34% at 52 months for allografted patients. Projected overall probability of survival +/- SE for all patients was 18.8 +/- 4.13% at 56 months. This study confirms the efficacy of IDA plus IDARA-C in poor-risk. ALL patients. A more intensive post-remission therapy or alternative approach must be designed to improve long-term results.

    Fifty-nine children, aged 1-15 years, with acute myelogenous leukemia (AML) received a bone marrow transplant (BMT) from an HLA-identical sibling (n = 57) or from an identical twin (n = 2), while in first remission (CR). These children represent, to the best of our knowledge, all children grafted in first CR in 11 Italian centers between 1980 and 1990. Patients were prepared with total body irradiation (TBI) plus cyclophosphamide (CY) (n = 50) or melphalan (n = 2) or with busulfan plus CY (n = 7). GVHD prophylaxis consisted of cyclosporin A (n = 48), methotrexate (n = 7) or cyclosporin and methotrexate (n = 2). Survivors have been followed for 21-137 months (median 59 months). Actuarial relapse-free survival was 58% at 66-137 months (95% confidence interval (CI) 44-72). Actuarial risk of relapse was 23% at 48 months (95% CI 10.9-34.8). Risk of non-relapse deaths was 33% in the period 1980-87 and 4% in the period 1988-90 (p = 0.02). In multivariate analysis patients with a blood cell count > 14 x 10(9)/l at diagnosis showed a lower relapse-free survival compared with patients with counts < 14 x 10(9)/l (p = 0.006). We could not detect an effect of FAB subtype, patient age, time to achieve remission or transplant-related variables, including year of BMT, on relapse-free survival. In conclusion, allogeneic marrow transplantation can achieve long-term relapse-free survival in over 50% of children with AML and should be considered as consolidation therapy if a matched sibling is available.(ABSTRACT TRUNCATED AT 250 WORDS)

All children treated by the Italian Paediatric Haematology Oncology Association for HR-ALL in first CR between 1986 and 1994 were eligible for the study. 30 children were given BMT at a median of 4 months from first CR, with preparative regimens including total-body irradiation (n = 25/30). 130 matched controls for BMT patients were identified among 397 HR-ALL CHEMO patients. Matching on main prognostic factors and duration of first CR was adopted to control the selection and time-to-transplant biases. The comparative analysis was based on the results of a stratified Cox model. The estimated hazard ratios of BMT versus CHEMO at 6 months, 1 year and 2 years after CR were 1.38 (CI 0.59-3.24), 0.69 (CI 0.27-1.77) and 0.35 (CI 0.06-1.91), with an overall non-significant difference between the two groups (P = 0.34). With a median follow-up of 4 years, the disease-free survival was 58.5% (SE 9.3) in the BMT group and 47.7% (SE 4.8) in the CHEMO group, at 4 years from CR. Non-leukaemic death occurred in 4% of CHEMO and 10% of BMT patients. In the BMT group the estimated cumulative incidence of relapse at 1.5 years from CR was 31.5% (SE 8.8) and did not change thereafter, whereas in the CHEMO group the corresponding figure was 29.2% (SE 4.1) and the incidence continued to increase thereafter (48.2% (SE 4.8) at 4 years from CR). The results of this study suggest that, with respect to the CHEMO group, the higher risk of early failure in the BMT group is outweighed by the lower risk of relapse after 1 year. Results prompt the need for a prospective study, in order to demonstrate the likely advantage of BMT in HR childhood ALL in first CR.

    Two hundred fifty-three patients with newly diagnosed acute promyelocytic leukemia (APL) were eligible to enter the multicentric GIMEMA-AIEOP "AIDA" trial during the period July 1993 to February 1996. As a mandatory prerequisite for eligibility, all patients had genetic evidence of the specific t(15;17) lesion in their leukemic cells confirmed by karyotyping or by reverse transcription-polymerase chain reaction (RT-PCR) of the PML/RAR alpha fusion gene (the latter available in 247 cases). Median age was 37.8 years (range, 2.2 to 73.9). Induction treatment consisted of oral all-trans retinoic acid (ATRA), 45 mg/m2/d until complete remission (CR), given with intravenous Idarubicin, 12 mg/m2/d on days 2, 4, 6, and 8. Three polychemotherapy cycles were given as consolidation. Hematologic and molecular response by RT-PCR was assessed after induction and after consolidation. At the time of analysis, 240 of the 253 eligible patients were evaluable for induction. Of these, 11 (5%) died of early complications and 229 (95%) achieved hematologic remission. No cases of resistant leukemia were observed. Of 139 cases studied by RT-PCR after induction, 84 (60.5%) were PCR-negative and 55 (39.5%) PCR-positive. One hundred sixty-two patients were evaluable by RT-PCR at the end of consolidation. Of these, 159 (98%) tested PCR-negative and 3 (2%), PCR-positive. After a median follow up of 12 months (range, 0 to 33), the estimated actuarial event-free survival for the whole series of 253 eligible patients was 83% +/- 2.6% and 79% +/- 3.2% at 1 and 2 years, respectively. This study indicates that the AIDA protocol is a well-tolerated regimen that induces molecular remission in almost all patients with PML/RAR alpha-positive APL. Preliminary survival data suggest that a remarkable cure rate can be obtained with this treatment.

    In the attempt to establish key therapy definitions and provide shared approaches to invasive fungal diseases in neutropenic patients, trials of empiric, preeemptive and targeted antifungal therapy (EAT, PAT and TAT) were reviewed, and a Consensus Development Conference Project was convened. The Expert-Panel concurred that all antifungal treatments, including EAT, should always follow an adequate diagnostic strategy and that the standard definition of PAT may be misleading: being PAT guided by the results of a diagnostic work-up, it should better be termed diagnostic-driven antifungal therapy (DDAT). The Expert-Panel agreed that radiological findings alone are insufficient for the choice of a TAT and that the identification of the etiologic pathogen is needed. The Consensus Agreement proceeded identifying which clinical and microbiological findings were sufficient to start a DDAT and which were not. Finally, an algorithm to rationalize the choice of antifungal drugs on the basis of clinical manifestations, antifungal prophylaxis, instrumental and laboratory findings was drawn up.

Riassunto Introduzione Le mappe tematiche consentono una più rapida ed immediata lettura delle differenze geografiche nella distribuzione di dati riferiti ad un territorio specifico. Lo scopo dello studio è mostrare, per la prima volta, l’applicazione di alcuni strumenti statistici e cartografici, nell’analisi dell’uso dei farmaci nella popolazione pediatrica di una regione italiana e valutare le differenze intra-regionali. Metodi Per valutare il tipo di distribuzione geografica delle prescrizioni, sono stati calcolati i tassi di prevalenza standardizzati (punteggi-z) a livello di ASL, Distretti Sanitari e Comuni. Per valutare la correlazione con le ospedalizzazioni è stato usato il coefficiente di correlazione di Pearson; per valutare l’esistenza di autocorrelazione spaziale è stato usato l’indice I di Moran. Tramite l’uso della statistica G di Getis-Ord sono stati identificati cluster di aree ad alto e basso livello di prevalenza. Infine con un modello di regressione logistica è stata stimata la probabilità di ricevere almeno una prescrizione nel corso dell’anno per tutti i pazienti inclusi nello studio. Risultati Con l’uso delle mappe è possibile vedere che le prescrizioni non sono correlate con lo stato di salute della popolazione, ma sono correlate con l’attitudine prescrittiva del pediatra. Questo è confermato anche dal modello di regressione logistica costruito per stimare la probabilità di ricevere almeno una prescrizione considerando come variabili indipendenti l’età, il sesso, la prevalenza di ricoveri nel distretto di residenza, l’attitudine prescrittiva del pediatra, la classe di età del pediatra e la durata della convenzione del pediatra con l’Azienda Sanitaria Locale (ASL).

    observations by the NASA-ESA Hubble Space Telescope, seeing Geminga as a faint visible star. The story will broaden into a hunt for other silent neutron stars like Geminga, using ESA's super-sensitive X-ray astronomy satellite XMM, due to be launched in 1999. Two years later XMM will be followed into orbit by Integral, ESA's successor to COS-B as a gamma-ray astronomy satellite of vastly enhanced performance. Another Hipparcos-Geminga co-author is Giovanni Bignami. He named Geminga in 1976 and has hunted it, with his colleagues in Milan, for more than 20 years. (In the Milanese argot, "ghèminga" means "it's not there" and referred to Geminga's invisibility at radio wavelengths.) Bignami is a principal investigator in the XMM mission, and is director for science in the Agenzia Spatiale Italiana, Rome. "Geminga is a shining example of how multinational collaboration in astronomy pays off," Bignami says. "We in Europe have done very well out of ESA in space astronomy, and also in our collaborations in ground observatories. We have world-class facilities that none of our home countries could offer us on their own. While governments ponder ESA's future role in science they should sense the surge of excitement throughout Europe, as astronomers beat all expectations in using the superb opportunities that come from ESA membership."

    Secondo Einstein e Poincaré la simultaneità di eventi che hanno luogo in punti diversi dello spazio può essere definita solo per convenzione. Dal punto di vista matematico si dimostra, quindi, che due diverse definizioni di simultaneità corrispondono a due diversi valori del coefficiente e1 della variabile spaziale x presente nelle trasformazioni di Lorentz. A partire da premesse normalmente accettate otterremo diverse dimostrazioni della necessità di reintrodurre il concetto di simultaneità assoluta. Le conseguenze cosmologiche della nuova struttura dello spazio e del tempo andranno contro la cosmologia del Big Bang. Inoltre, dopo questi risultati, il relativismo sopravviverà in una forma meno aspra ("relatività debole") perché risulter privo di quel campionario di paradossi portato dalla teoria della Relatività Speciale.

    The risk of landslide hazard continuously changes in time and space and is rarely a static or constant phenomena in an affected area. However one of the main challenges of quantitatively assessing changes in landslide risk is the availability of multi-temporal data for the different components of risk. Furthermore, a truly "quantitative" landslide risk analysis requires the modeling of the landslide intensity (e.g. flow depth, velocities or impact pressures) affecting the elements at risk. Such a quantitative approach is often lacking in medium to regional scale studies in the scientific literature or is left out altogether. In this research we modelled the temporal and spatial changes of debris flow risk in a narrow alpine valley in the North Eastern Italian Alps. The debris flow inventory from 1996 to 2011 and multi-temporal digital elevation models (DEMs) were used to assess the susceptibility of debris flow triggering areas and to simulate debris flow run-out using the Flow-R regional scale model. In order to determine debris flow intensities, we used a linear relationship that was found between back calibrated physically based Flo-2D simulations (local scale models of five debris flows from 2003) and the probability values of the Flow-R software. This gave us the possibility to assign flow depth to a total of 10 separate classes on a regional scale. Debris flow vulnerability curves from the literature and one curve specifically for our case study area were used to determine the damage for different material and building types associated with the elements at risk. The building values were obtained from the Italian Revenue Agency (Agenzia delle Entrate) and were classified per cadastral zone according to the Real Estate Observatory data (Osservatorio del Mercato Immobiliare, Agenzia Entrate - OMI). The minimum and maximum market value for each building was obtained by multiplying the corresponding land-use value (€/msq) with building area and number of floors

    This document is a Joint Position Statement by Gruppo Italiano di OrtoGeriatria (GIOG) supported by Società Italiana di Gerontologia e Geriatria (SIGG), and Associazione Italiana Psicogeriatria (AIP) on management of hip fracture older patients. Orthogeriatric care is at present the best model of care to improve results in older patients after hip fracture. The implementation of orthogeriatric model of care, based on the collaboration between orthopaedic surgeons and geriatricians, must take into account the local availability of resources and facilities and should be integrated into the local context. At the same time the programme must be based on the best available evidences and planned following accepted quality standards that ensure the efficacy of the intervention. The position paper focused on eight quality standards for the management of hip fracture older patients in orthogeriatric model of care. The GIOG promotes the development of a clinic database with the aim of obtaining a qualitative improvement in the management of hip fracture. PMID:24566982

    Patients with esophageal symptoms potentially associated to esophageal motor disorders such as dysphagia, chest pain, heartburn and regurgitation, represent one of the most frequent reasons for referral to gastroenterological evaluation. The utility of esophageal manometry in clinical practice is: (1) to accurately define esophageal motor function, (2) to identify abnormal motor function, and (3) to establish a treatment plan based on motor abnormalities. With this in mind, in the last decade, investigations and technical advances, with the introduction of high-resolution esophageal manometry, have enhanced our understanding and management of esophageal motility disorders. The following recommendations were developed to assist physicians in the appropriate use of esophageal manometry in modern patient care. They were discussed and approved after a comprehensive review of the medical literature pertaining to manometric techniques and their recent application. This position statement created under the auspices of the Gruppo Italiano di Studio per la Motilità dell'Apparato Digerente (GISMAD), Società Italiana di Gastroenterologia ed Endoscopia Digestiva (SIGE) and Associazione Italiana Gastroenterologi ed Endoscopisti Digestivi Ospedalieri (AIGO) is intended to help clinicians in applying manometric studies in the most fruitful manner within the context of their patients with esophageal symptoms.

    Progress in head and neck cancer (HNC) therapies has improved tumor response, loco-regional control, and survival. However, treatment intensification also increases early and late toxicities. Dysphagia is an underestimated symptom in HNC patients. Impairment of swallowing process could cause malnutrition, dehydration, aspiration, and pneumonia. A comprehensive literature review finalized in May 2012 included searches of electronic databases (Medline, Embase, and CAB abstracts) and scientific societies meetings materials (American Society of Clinical Oncology, Associazione Italiana Radioterapia Oncologica, Associazione Italiana di Oncologia Cervico-Cefalica, American Head and Neck Society, and European Society for Medical Oncology). Hand-searches of HNC journals and reference lists were carried out. Approximately one-third of dysphagia patients developed pneumonia requiring treatment. Aspiration pneumonia associated mortality ranged from 20% to 65%. Unidentified dysphagia caused significant morbidity, increased mortality, and decreased the quality of life. In this review we underline definition, causes, predictive factors of dysphagia and report on pretreatment and on-treatment evaluation, suggesting some key points to avoid underestimation. A multi-parameter assessment of swallowing problems may allow an earlier diagnosis. An appropriate evaluation might lead to a better treatment of both symptoms and cancer. PMID:24069513

    A 1/12° by 1/12° two-dimensional, hydrodynamic tide-surge model for the Mediterranean Sea is used to model two storm surge events in the Adriatic Sea. The impact of meteorological forcing on the model results is investigated using three different sources of data: observations obtained from the UK Meteorological Office, operational analysis model data from the European Centre for Medium Range Weather Forecasting and a local area model for the Adriatic region obtained from Agenzia Regionale Prevenzione e Ambiente dell'Emilia-Romagna, Italy. Two surge events are studied, one under conditions of bora wind (December 1995) and the other for a sirocco wind (November 1997). The model results are compared to hourly data from tide gauges in the northern Adriatic Sea. The three meteorological forcing fields produce storm surge elevations with generally similar behaviour but which differ from each other by up to 60 cm in height. The results obtained by using the UK Meteorological Office data were generally better than those obtained by using either of the two sets of meteorological model data. The model results give periods of 21.3, 11.6, 7.3 and 5.6 h for the Adriatic Sea seiches that are produced by the excitation of the fundamental longitudinal oscillation.

    In the framework of the National Project “Sviluppo di distretti industriali per le Osservazioni della Terra” (Development of Industrial Districts for Earth Observations) funded by MIUR (Ministero dell'Università e della Ricerca Scientifica --Italian Ministry of the University and Scientific Research) two operational mesoscale models were set-up for Calabria, the southernmost tip of the Italian peninsula. Models are RAMS (Regional Atmospheric Modeling System) and MM5 (Mesoscale Modeling 5) that are run every day at Crati scrl to produce weather forecast over Calabria (http://www.crati.it). This paper reports model intercomparison for Quantitative Precipitation Forecast evaluated for a 20 month period from 1th October 2000 to 31th May 2002. In addition to RAMS and MM5 outputs, QBOLAM rainfall fields are available for the period selected and included in the comparison. This model runs operationally at “Agenzia per la Protezione dell'Ambiente e per i Servizi Tecnici”. Forecasts are verified comparing models outputs with raingauge data recorded by the regional meteorological network, which has 75 raingauges. Large-scale forcing is the same for all models considered and differences are due to physical/numerical parameterizations and horizontal resolutions. QPFs show differences between models. Largest differences are for BIA compared to the other considered scores. Performances decrease with increasing forecast time for RAMS and MM5, whilst QBOLAM scores better for second day forecast.

    2009-04-01

    The Italian Avalanche Warning Services monitor the snow cover characteristics through networks evenly distributed all over the alpine chain. Measurements of snow stratigraphy and density are very frequently performed with sampling rates of 1 -2 times per week. Snow cover density values are used to compute the dimensions of the building roofs as well as to design avalanche barriers. Based on the measured snow densities the Electricity Board can predict the amount of water resources deriving from snow melt in high relieves drainage basins. In this work it was possible to compute characteristic density values of the snow cover in the Eastern Alps using the information contained in the database from the ARPA (Agenzia Regionale Protezione Ambiente)-Centro Valanghe di Arabba, and Ufficio Valanghe- Udine. Among the other things, this database includes 15 years of stratigraphic measurements. More than 6,000 snow stratigraphic logs were analysed, in order to derive typical values as for geographical area, altitude, exposure, snow cover thickness and season. Computed values were compared to those established by the current Italian laws. Eventually, experts identified and evaluated the correlations between the seasonal variations of the average snow density and the variations related to the snowfall rate in the period 1994-2008 in the Eastern Alps mountain range

    The Campo Imperatore Near Earth Object Survey (CINEOS) is an Italian survey dedicated to the search and follow-up of Near Earth Objects (NEOs). It is operated with the 90 cm f/3 Schmidt telescope at the Campo Imperatore of the Rome Astronomical Observatory (INAF-OAR) as a joint project with the Istituto di Astrofisica Spaziale and Fisica Cosmica (INAF-IASF) in Rome. Since the end of 2001 CINEOS has covered about 4,250 sq. deg to 20th magnitude in the course of about 160 nights. This effort led to the discovery of 7 Near Earth Asteroids (NEAs), 1 comet (167P/CINEOS; a member of the Centaur group) and a few other unusual objects including 2004 XH50 with a unique comet-like orbit. CINEOS has also contributed almost 2,200 preliminary designations and over 30,000 detections to the Minor Planet Center. About 20% of the survey effort was carried out at low solar elongations (LSE), although no object with an orbit interior (Inner Earth Objects, IEO class) or nearly interior to the Earth (Aten class) was found. The work at LSE was, however, very important to test survey strategies implemented with larger telescopes. We also provide the results of a CINEOS simulation on a reliable NEO population model based on the results of two larger scale surveys, Spacewatch and LINEAR.

    The X-band synthetic aperture radar (X-SAR) is the German/Italian contribution to the NASA/JPL Shuttle Radar Lab missions as part of the preparation for the Earth Observation System (EOS) program. The Shuttle Radar Lab is a combination of several radars: an L-band (1.2 GHz) and a C-band (5.3 GHz) multipolarization SAR known as SIR-C (Shuttle Imaging Radar); and an X-band (9.6 GHz) vertically polarized SAR which will be operated synchronously over the same target areas to deliver calibrated multifrequency and multipolarization SAR data at multiple incidence angles from space. A joint German/Italian project office at DARA (German Space Agency) is responsible for the management of the X-SAR project. The space hardware has been developed and manufactured under industrial contract by Dornier and Alenia Spazio. Besides supporting all the technical and scientific tasks, DLR, in cooperation with ASI (Agencia Spaziale Italiano) is responsible for mission operation, calibration, and high precision SAR processing. In addition, DLR developed an airborne X-band SAR to support the experimenters with campaigns to prepare for the missions. The main advantage of adding a shorter wavelength (3 cm) radar to the SIR-C radars is the X-band radar's weaker penetration into vegetation and soil and its high sensitivity to surface roughness and associated phenomena. The performance of each of the three radars is comparable with respect to radiometric and geometric resolution.

    Fundamento y objetivo: El análisis de vectores de impedancia es útil para la determinación de la composición corporal en pacientes con alteración del estado de hidratación. Las elipses de tolerancia originales fueron hechas en individuos sanos italianos. Debido a las diferencias en composición corporal entre poblaciones, el objetivo del estudio fue establecer elipses de tolerancia específicas para la población española y compararlas con las elipses realizadas en la población original de referencia. Material y método: Se estudiaron 311 sujetos sanos españoles de ambos sexos, entre 18 y 80 años, con IMC entre 18 y 31 Kg/m2, a los cuales se les realizaron mediciones de peso, estatura e impedancia bioeléctrica. Los valores de resistencia y reactancia estandarizadas por la estatura (R/E y Xc/E) derivados de la medición de impedancia, fueron utilizados para determinar la composición corporal y realizar las elipses de referencias específicas para dicha población. Resultados: Las características de composición corporal fueron diferentes entre sexos y grupo etario. Se graficaron los valores de R/E y Xc/E de la población española sobre las elipses de tolerancia italianas, encontrándose que los vectores se situaban en los cuadrantes izquierdos, indicando diferente composición corporal, por lo que se construyeron elipses de tolerancia específicas para la población española a partir de los valores de R/E y Xc/E. Las elipses de tolerancia españolas fueron estadísticamente diferentes a las italianas. Conclusiones: Los vectores de la población española fueron diferentes a los de la población italiana, de ahí la importancia de tener un patrón de referencia propio.

    ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) SST-2M is an end-to-end prototype of Small Size class of Telescope for the Cherenkov Telescope Array. It will apply a dual mirror configuration to Imaging Atmospheric Cherenkov Telescopes. The 18 segments composing the primary mirror (diameter 4.3 m) are equipped with an active optics system enabling optical re-alignment during telescope slew. The secondary mirror (diameter 1.8 m) can be moved along three degrees of freedom to perform focus and tilt corrections. We describe the kinematic model used to predict the system performance as well as the hardware and software design solution that will be implemented for optics control.

    ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana), is a flagship project of the Italian Ministry of Education, University and Research whose main goal is the design and construction of an end-to-end prototype of the Small Size of Telescopes of the Cherenkov Telescope Array. The prototype, named ASTRI SST-2M, will adopt a wide field dual mirror optical system in a Schwarzschild-Couder configuration to explore the VHE range of the electromagnetic spectrum. The camera at the focal plane is based on Silicon Photo-Multipliers detectors which is an innovative solution for the detection astronomical Cherenkov light. This contribution reports some preliminary results on the evaluation of the optical cross talk level among the SiPM pixels foreseen for the ASTRI SST-2M camera.

    The International Astronomy Olympiad (IAO) is an internationally annual astronomy scientific-educating event, born in 1996, which includes an intellectual competition between students aged between 14 and 17. In Italy, the Olympiad is coorganized since 2007 by INAF (Istituto Nazionale di Astrofisica) and SAiT (Società Astronomica Italiana) becoming every year a more visible and global event in the italian scenario (in 2011, INAF institutes participating to the local activities were 13). Unluckily, the Italian Committee of the Olympiads cannot involve directly nor rely on schools, since astronomy is no longer part of the scholastic programs. For this reason, the Committee needed to develop in the last years a non traditional mediatic approach that allowed in 2011 to reach a participation of more than 500 teenagers to the Olympics. We will give an overview of the Astronomy Olympics project in Italy and of this non conventional mediatic approach.

    The article reconstruct the situation of Italian psychiatry around 1930, using as unusual sources the pages of the Enciclopedia Italiana di Scienze, Lettere e Arti. This important work, conceived in 1925 and finished in 1937, is due - as well known - to the strong interest of Giovanni Gentile and to his capacity to involve in the project a great part of Italian intellectual world, without any ideological preclusion. The section devoted to Medical Sciences, including Psychiatry, was directed by Nicola Pende (1880-1970) and Giacinto Viola (1870-1943). A prevalent positivistic approach to science is well testified by their specific attention to preventive and social medicine, researches in Genetics and in biotypological constitutions. Psycopathological and psycological lemmas are very limited, underlying the medical disinterest towards contemporary philosophy and psycology.

    The scientific heritage held in the National Institute for Astrophysics (INAF), made up of rare and modern books, instruments, and archival documents spanning from the 15th to the early 20th century, marks the milestones in the history of astronomy in Italy. To promote this history of this historical collection, the Libraries and Historical Archives Service and the Museums Service of INAF have developed a project aimed at creating a single web portal: Polvere di stelle. I beni culturali dell'astronomia italiana (Stardust. The cultural heritage of the Italian astronomy). This portal searches for data coming from the libraries, the instruments collections and the historical archives, regarding the heritage of the Italian Observatories. The BID (Books, Instruments, Documents) of the project is the creation of a multimedia web facility, which allows the public to make simultaneous searches on the three different types of materials.

    In this study, two raptor species, the common buzzard (Buteo buteo) and the little owl (Athene noctua), were investigated for lead and cadmium concentrations, using liver, kidneys, pectoral muscle, sternum bone, and feathers. All the collected birds died at the Centro Recupero Rapaci of Lega Italiana Protezione Uccelli in Sala Baganza (Parma, Italy). They arrived alive at the Centro between November 1998 and November 1999 but died or were put to death as a consequence of injuries or other ailments. The results of the investigation do not show an excessive exposure to cadmium, whereas some interesting data have emerged in the case of lead. The concentration of the latter in the liver and in the bone of two little owls seem to suggest the possibility of chronic exposure. The high values found in one common buzzard, on the other hand, suggest an acute exposure and, probably, a case of lead shot ingestion.

    Osteoporosis (OP) and related fractures are well-known severe conditions affecting quality of life and life expectancy of postmenopausal women, with high economic costs in Europe. On behalf of The Italian Society of Gynecology and Obstetrics (Società Italiana di Ginecologia ed Ostetricia, SIGO), the Osteoporosis's Menopausal Epidemiological Risk Observation (O.M.E.R.O.) study, a national multicenter study on clinical risk factors of OP was organized, using FRAX® tool as a reference. Here, data from this study are presented, showing an important portion of Italian postmenopausal women affected by osteopenia/OP at high risk of fracture and the need to do prevention and/or treatment. Gynecologist can be a primary specialist in this important challenge.

    This analysis compared the numbers of patients treated at Italian pediatric oncology group (Associazione Italiana Ematologia Oncologia Pediatrica [AIEOP]) centers with the numbers of cases predicted according to the population-based registry. It considered 32,431 patients registered in the AIEOP database (1989-2012). The ratio of observed (O) to expected (E) cases was 0.79 for children (0-14 years old) and 0.15 for adolescents (15-19 years old). The proportion of adolescents increased significantly over the years, however, from 0.05 in the earliest period to 0.10, 0.18, and then 0.28 in the latest period of observation, suggesting a greater efficacy of local/national programs dedicated to adolescents.

    Few data are available on the incidence of carbapenemase-producing Enterobacteriaceae (CPE) infection or colonization in children receiving anticancer chemotherapy. We performed a nationwide survey among centers participating in the pediatric hematology-oncology cooperative study group (Associazione Italiana Ematologia Oncologia Pediatrica, AIEOP). During a 2-year observation period, we observed a threefold increase in the colonization rate, and a fourfold increase of bloodstream infection episodes, caused by CPE, with a 90-day mortality of 14%. This first nationwide Italian pediatric survey shows that the circulation of CPE strains in the pediatric hematology-oncology environment is increasing. Given the mortality rate, which is higher than for other bacterial strains, specific monitoring should be applied and the results should have implications for health-care practice in pediatric hematology-oncology.

    INTRODUZIONE. Lo stress occupazionale è una delle principali cause di malattie professionali e di assenze da lavoro e genera costi sanitari e sociali molto elevati; la comprensione del problema è stata l'obiet- tivo di numerosi studi. Monitorare lo stress negli infermieri può essere uno strumento per chi ha la responsabilità della gestione delle risorse umane nel sistema sanitario. La ricerca infermieristica italiana si è occupata solo marginalmente di stress lavorativo infermieristico. Gli obiettivi di questo studio sono dunque: stimare la prevalenza di stress tra gli infermieri di tre ospedali, in modo da disporre di dati epidemiologici per valutare la necessità di interventi di prevenzione e di trattamento del fenomeno; analizzare eventuali fattori di rischio e fattori protettivi in modo da progettare interventi preventivi mirati.

    Sommario INTRODUZIONE: Riportiamo i dati di un'indagine conoscitiva sulla diffusione, pratica e organizzazione dell'ecografia (US) nei dipartimenti di emergenza (EMDs) in Italia. Questo studio è stato condotto dalla Sezione di Ecografia di Urgenza Emergenza della Società Italiana di Ecografia in Medicina e Biologia (SIUMB) in collaborazione con la Società Italiana di Medicina di Emergenza e Urgenza (SIMEU). METODI: Abbiamo creato un questionario con 10 campi, relativi a 4 aree tematiche. I questionari sono stati somministrati nel periodo settembre 2007-febbraio 2008, via e-mail, telefono o posta ordinaria. I dati sono stati analizzati con metodi statistici non parametrici nell'Agosto 2008. RISULTATI: Abbiamo analizzato 170 questionari provenienti dagli EMDs di tutte le regioni italiane. Un ecografo è presente nel 64,7% dei Pronto Soccorso, l'ecografia d'emergenza (E-US) è praticata solo nel 47,6% dei Pronto Soccorso, e solo nel 24% di questi più del 60% dei membri dell'èquipe è formata in ecografia. La diffusione degli US in altre Unità Operative degli EMDs va dall'8,2% al 26,5%. DISCUSSIONE: La presenza di un ecografo in Pronto Soccorso è essenziale per la pratica e la formazione e è correlata al livello del Dipartimento di Emergenza (I o II). L'uso dell'Ecografia sembra essere minore negli ospedali meno attrezzati, indipendentemente dalla grandezza del Pronto Soccorso e dalla disponibilità di Servizi di Radiologia. Si auspica una maggiore diffusione dell'ecografia e una maggiore integrazione con altri servizi quanto all'allocazione delle risorse richieste.

    The dense atmosphere of Venus prevented systematic studies of its surface at optical wavelengths in the past. The discovery of near infrared nightside atmospheric windows has opened a new challenge for detailed surface studies. The Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) on Venus Express is the first experiment collecting continuously nightside surface emission data from the planet. The observed high variability of measured signatures is mainly due to spatial variations of cloud optical depth and surface elevation. The investigation of surface properties requires a convergent approach of radiative transfer simulations and VIR- TIS data analyses. Therefore, a selection of orbits with well calibrated data over the northern hemisphere was performed for footprints that cover a maximum range of surface elevation variations. Radiative transfer calculations demonstrate that the conservative character of cloud multiple scattering below 2 µm and a strong dependence of radiance ratios on surface elevation in this spectral region allow the mapping of surface topography and a retrieval of the surface temperature. To the first order, the surface temperature is a function of ground elevation. Small deviations from this first order dependence have been identified that are possibly due to different surface materials. 1 Institut f¨r Planetologie, Westf¨lische Wilhelms-Universit¨t M¨nster, Wilhelm-Klemm-Str.10, u a a u 48129 M¨nster, Germany u 2 German PlaceNameAerospace PlaceTypeCenter (DLR), Remote Sensing Technology Institute, Dpt.

    This thesis is the result of my work as research fellow at IASF-MI, Milan section of the Istituto di Astrofisica Spaziale e Fisica Cosmica, part of INAF, Istituto Nazionale di Astrofisica. This work started in January 2006 in the context of the PhD school program in Astrophysics held at the Physics Department of Universita' degli Studi di Milano under the supervision of Aniello Mennella. The main topic of my work is the software modelling of the Low Frequency Instrument (LFI) radiometers. The LFI is one of the two instruments on-board the European Space Agency Planck Mission for high precision measurements of the anisotropies of the Cosmic Microwave Background (CMB). I was also selected to participate at the International Doctorate in Antiparticles Physics, IDAPP. IDAPP is funded by the Italian Ministry of University and Research (MIUR) and coordinated by Giovanni Fiorentini (Universita' di Ferrara) with the objective of supporting the growing collaboration between the Astrophysics and Particles Physics communities. It is an international program in collaboration with the Paris PhD school, involving Paris VI, VII and XI Universities, leading to a double French-Italian doctoral degree title. My work was performed with the co-tutoring of Jean-Michel Lamarre, Instrument Scientist of the High Frequency Instrument (HFI), the bolometric instrument on-board Planck. Thanks to this collaboration I had the opportunity to work with the HFI team for four months at the Paris Observatory, so that the focus of my activity was broadened and included the study of cross-correlation between HFI and LFI data. Planck is the first CMB mission to have on-board the same satellite very different detection technologies, which is a key element for controlling systematic effects and improve measurements quality.

    Rainfall is the primary trigger of shallow landslides that can cause fatalities, damage to properties and economic losses in many areas of the world. For this reason, determining the rainfall amount/intensity responsible for landslide occurrence is important, and may contribute to mitigate the related risk and save lives. Efforts have been made in different countries to investigate triggering conditions in order to define landslide-triggering rainfall thresholds. The rainfall thresholds are generally described by a functional relationship of power in terms of cumulated or intensity event rainfall-duration, whose parameters are estimated empirically from the analysis of historical rainfall events that triggered landslides. The aim of this paper is the derivation of critical rainfall thresholds for landslide occurrence in Sicily, southern Italy, by focusing particularly on the role of the antecedent wet conditions. The creation of the appropriate landslide-rainfall database likely represents one of main efforts in this type of analysis. For this work, historical landslide events occurred in Sicily from 1919 to 2001 were selected from the archive of the Sistema Informativo sulle Catastrofi Idrogeologiche, developed under the project Aree Vulnerabili Italiane. The corresponding triggering precipitations were screened from the raingauges network in Sicily, maintained by the Osservatorio delle Acque - Agenzia Regionale per i Rifiuti e le Acque. In particular, a detailed analysis was carried out to identify and reconstruct the hourly rainfall events that caused the selected landslides. A bootstrapping statistical technique has been used to determine the uncertainties associated with the threshold parameters. The rainfall thresholds at different exceedance probability levels, from 1% to 10%, were defined in terms of cumulated event rainfall, E, and rainfall duration, D. The role of rainfall prior to the damaging events was taken into account by including in the analysis

    In the past water resources management has been dealt and solved increasing water availabilities; today such opportunities have been considerably reduced and the technical-scientific perspectives are addressed above all to improve water system effectiveness and to promote an use of water resources that holds account of the droughts frequency and based on a correct estimate of the hydrologic balance. In this work a study on the water stored in Monte Cotugno reservoir in Sinni river - Basilicata (Southern Italy) - is proposed, estimating water crises return periods and reservoir evaporation. For such purpose the runs method was applied, based on the comparison between the temporal series of the "water volume" hydrological variable and a threshold representative of the "normal" conditions regarding which the availability in excess or defect was estimated. This allowed to individualize the beginning and the end of a water crisis event and to characterize the droughts in terms of duration, sum deficit and intensity. Therefore the return period was evaluated by means of the methodology proposed by Shiau and Shen in 2001, turned out equal approximately to 6 years. Such value was then verified with a frequency analysis of the "water volume" random variable, using the Weibull's distribution. Subsequently, the Fourier's analysis in the last twenty years was carried out, obtaining the same result of the previous methods. Moreover, in proximity of the Monte Cotugno reservoir the weather station of Senise is located, managed by ALSIA (Agenzia Lucana di Sviluppo e Innovazione in Agricultura), that provides in continuous measurements of air temperature and humidity, wind speed and direction, and global solar radiation since 2000. Such parameters allowed to apply five methods for reservoir evaporation estimate selected from those proposed in the literature, of which the first three, the Jensen-Haise's method, Makkink's method and Stephens-Stewart's one are based on solar radiation

    The interaction of aerosol with atmospheric water affects the processing and wet removal of atmospheric particles. Understanding such interaction is mandatory to improve model description of aerosol lifetime and ageing. We analyzed the aerosol-water interaction at high relative humidity during fog events in the Po Valley within the framework of the Agenzia Regionale per la Prevenzione e l'Ambiente (ARPA) - Emilia Romagna supersite project. For the first time in this area, the changes in particle chemical composition caused by fog are discussed along with changes in particle microphysics. During the experiment, 14 fog events were observed. The average mass scavenging efficiency was 70% for nitrate, 68% for ammonium, 61% for sulfate, 50% for organics, and 39% for black carbon. After fog formation, the interstitial aerosol was dominated by particles smaller than 200 nm Dva (vacuum aerodynamic diameter) and enriched in carbonaceous aerosol, mainly black carbon and water-insoluble organic aerosol. For each fog event, the size-segregated scavenging efficiency of nitrate and organic aerosol (OA) was calculated by comparing chemical species size distribution before and after fog formation. For both nitrate and OA, the size-segregated scavenging efficiency followed a sigmoidal curve, with values close to zero below 100 nm Dva and close to 1 above 700 nm Dva. OA was able to affect scavenging efficiency of nitrate in particles smaller than 300 nm Dva. A linear correlation between nitrate scavenging and particle hygroscopicity (κ) was observed, indicating that 44-51% of the variability of nitrate scavenging in smaller particles (below 300 nm Dva) was explained by changes in particle chemical composition. The size-segregated scavenging curves of OA followed those of nitrate, suggesting that organic scavenging was controlled by mixing with water-soluble species. In particular, functional group composition and OA elemental analysis indicated that more oxidized OA was scavenged

    In the map sheets of the Second Military Survey of the Habsburg Empire, Lombardia, Parma, Modena and Venice also can be seen (Timár et al., 2006). This area was surveyed between 1818 and 1829. In these map sheets, we can also follow the river Po from Vaccarizza to the delta. This river reach is about 350 km long. This river reach was digitized and sinuosity values were calculated with different window sizes, and displayed in a spectrum-like diagram (sinuosity spectra; after van Balen et al., 2008). At Cremona, a significante sinuosity change were identified. The sinuosity increasing, and we have high sinuosity values. In the summarizing geological map of Italy (Compagnoni and Calluzzo, 2004), at this place, a tectonic line was identified. So probably this fault line invokes the sinuosity change on the river. The vertical movements indicated on the maps are just the opposite like they would be according to the flume experiments of Ouchi (1985). In the case of the Po River at Cremona, the decrease of the channel slope results higher sinuosity. The reason is that the rate of the slope and water discharge is higher than it is required by the self-organized meandering and the river parameters fell to the range of the unorganized meandering (cf. Timár, 2003). Another possible explanation could be that the northern tributary, the Adda River has significant sediment load that lowers the sinuosity of the trunk river at the confluence.

    In the last century, pollution has become one of the most important risks for environment. In particular, heavy metal presence in air, water and soil induces toxic effects on ecosystems and human health. Monitoring airborne trace element over large areas is a task not easy to reach since the concentrations of pollutants are variable in space and time. Data from automatic devices are site-specific and very limited in number to describe spatial-temporal trends of pollutants. In addition, especially in Italy, trace elements concentrations are not often recorded by most of the automated monitoring stations. In the last decades, development of alternative and complementary methods as bio-monitoring techniques, allowed to map deposition patterns not only near single pollution sources, but also over relatively large areas at municipal or even regional scale. Bio-monitoring includes a wide array of methodologies finalised to study relationships between pollution and living organisms. Mosses and lichens have been widely used as bio-accumulators for assessing the atmospheric deposition of heavy metals in natural ecosystems and urban areas. In this study bio-monitoring of airborne trace metals was made using moss bags technique. The moss Hypnum cupressiforme was used as bio-indicator for estimating atmospheric traces metal deposition in the urban area of Florence. Moss carpets were collected in a forested area of central Sardinia (municipality of Bolotana - Nuoro), which is characterised by absence of air pollution. Moss bags were located in the urban area of Florence close to three monitoring air quality stations managed by ARPAT (Agenzia Regionale Protezione Ambiente Toscana). Two stations were located in high-traffic roads whereas the other one was located in a road with less traffic density. In each site moss bags were exposed during three campaigns of measurement conducted during the periods March-April, May-July, and August-October 2010. Two moss bags, used as control

    An outstanding issue in magnetic confinement is the establishment of MHD equilibria with enhanced flow shear profiles for which turbulence (and transport) may be locally effectively suppressed or at least substantially reduced with respect to standard weak turbulence models. Strong flows develop in the presence of equilibrium E× B-drifts produced by a strong radial electric field, as well as due to diamagnetic contributions produced by steep equilibrium radial profiles of number density, temperature and the flow velocity itself. In the framework of a kinetic description, this generally requires the construction of guiding-center variables correct to second order in the relevant expansion parameter. For this purpose, the Lagrangian approach developed recently by Tessarotto et al. [1] is adopted. In this paper the conditions of existence of such equilibria are analyzed and their basic physical properties are investigated in detail. 1 - M. Pozzo, M. Tessarotto and R.

    ASTRI ("Astrofisica con Specchi a Tecnologia Replicante Italiana") is a flagship project of the Italian Ministry of Education, University and Research. Within this framework, INAF is currently developing a wide field of view (9.6° in diameter) end-to-end prototype of the CTA smallsize telescope (SST), devoted to the investigation of the energy range from a fraction of TeV up to (possibly) hundreds of TeV, and scheduled to start data acquisition in 2014. For the first time, a dualmirror Schwarzschild-Couder optical design will be adopted on a Cherenkov telescope, in order to obtain a compact (FNo. = 0.5) optical configuration. A second challenging, but innovative technical solution consists of a focal plane camera based on Silicon photo-multipliers with a logical pixel size of 0.17° (6.2mm × 6.2mm). We will describe the current status of the project, the results obtained so far, the expected performance, and its possible evolution in terms of a SST mini-array (composed of 5-7 SSTs and developed in collaboration with CTA international partners), which could peruse not only the adopted technological solutions, but also address a few scientific test cases.

    The method of calculation described is useful for the types of work of which examples are given. It is also useful in making rapid comparison of the activities that might be expected from several different elements. For instance, suppose it is desired to know which of the three elements, cobalt, nickel, or vanadium is, under similar conditions, activated to the greatest extent by thermal neutrons. If reference is made to a cross-section table only, the values may be misleading unless properly interpreted by a suitable comparison of half-lives and abundances. In this table all the variables have been combined and the desired information can be obtained directly from the values of A 3??, the activity produced per gram per second of irradiation, under the stated conditions. Hence, it is easily seen that, under similar circumstances of irradiation, vanadium is most easily activated even though the cross section of one of the cobalt isotopes is nearly five times that of vanadium and the cross section of one of the nickel isotopes is three times that of vanadium. ?? 1954 Societa??

    The National Project RITMARE (la Ricerca ITaliana per il MARE-Italian Research for the sea) started from 1 January 2012. It is one of the national research programs funded by the Italian Ministry of University and Research. RITMARE is coordinated by the National Research Council (CNR) and involves an integrated effort of most of the scientific community working on marine and maritime issues. Within the project, different marine study areas of strategic importance for the Mediterranean have been identified: Among these, the coastal area of Taranto (Ionian Sea, Southern Italy) was chosen for its different industry settlements and the relative impact on the marine environment. In particular, the research has been concentrated on the Mar Piccolo of Taranto, a complex marine ecosystem model important in terms of ecological, social, and economic activities for the presence also of extensive mussel farms. The site has been selected also because the Mar Piccolo area is a characteristic "on field" laboratory suitable to investigate release and diffusion mechanisms of contaminants, evaluate chemical-ecological risks towards the marine ecosystem and human health, and suggest and test potential remediation strategies for contaminated sediments. In this context, within the project RITMARE, a task force of researchers has contributed to elaboration a functioning conceptual model with a multidisciplinary approach useful to identify anthropogenic forcings, its impacts, and solutions of environmental remediation. This paper describes in brief some of the environmental issues related to the Mar Piccolo basin. PMID:26111753

    We present an optical method for free-form mirrors qualification developed by the Italian National Institute for Astrophysics (INAF) in the context of the ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Project which includes, among its items, the design, development and installation of a dual-mirror telescope prototype for the Cherenkov Telescope Array (CTA) observatory. The primary mirror panels of the telescope prototype are free-form concave mirrors with few microns accuracy required on the shape error. The developed technique is based on the synergy between a Ronchi-like optical test performed on the reflecting surface and the image, obtained by means of the TraceIT ray-tracing proprietary code, a perfect optics should generate in the same configuration. This deflectometry test allows the reconstruction of the slope error map that the TraceIT code can process to evaluate the measured mirror optical performance at the telescope focus. The advantages of the proposed method is that it substitutes the use of 3D coordinates measuring machine reducing production time and costs and offering the possibility to evaluate on-site the mirror image quality at the focus. In this paper we report the measuring concept and compare the obtained results to the similar ones obtained processing the shape error acquired by means of a 3D coordinates measuring machine.

    Two species of Melissa are currently present in Sardinia: Melissa officinalis L. and Melissa romana Mill. Our research can only count on a few supported evidences (as reported in Flora Italiana and Moris) and some notes on new stations in Sardinia that give us some information about morphology, distribution, bioecological, and ethnobotanical characteristics of both species. In this paper, we present the results of the research about morphological aspects of M. romana vs. M. officinalis, and their essential oils in different stations at different phenological periods. Moreover, we compared the essential oil of M. romana with the one obtained from M. officinalis growing in the few naturalized stations still present in Sardinia. The most evident morphological differences between the two entities are the long-stalked capitate glandular trichomes, shorts and inclined capitate trichomes, and peltate hairs. The chemical composition of essential oil presents several significant differences between the species. In fact, oils show that in none of the phenological stages, M. romana recalls in its composition M. officinalis. Major distinctions are also evident between dry and fresh plants, and among essential oils distilled in different seasons. PMID:27449960

    Allergic contact dermatitis (ACD) and photo-ACD are cell-mediated delayed hypersensitivity reactions of the skin caused by a wide range of substances. Topical ketoprofen (KP), a nonsteroidal anti-inflammatory drug (NSAID), can induce ACD and photo-ACD. Patients with ACD and/or photo-ACD to KP frequently show concomitant sensitization to other substances. The aim of this study was to identify the substances most frequently associated with sensitization to KP, and to evaluate, by means of computerized conformational analysis, whether this association could be due to cross-allergy. 15 subjects with ACD and photo-ACD to KP were tested with the SIDAPA (Società Italiana di Dermatologia Allergologica Professionale ed Ambientale) patch test standard series, including fragrance mix and its components (eugenol, isoeugenol, oak moss, geraniol, hydroxycitronellal, amylcinnamaldehyde, cinnamyl alcohol and cinnamaldehyde) and with the SIDAPA photopatch test series. Allergic reactions to cinnamyl alcohol were noted in all patients, whereas some patients also showed positive reactions to fenticlor, octocrylene and benzophenone-10. Computerized conformational analysis demonstrated that the structure of cinnamyl alcohol is similar to that of KP, whereas the structures of benzophenone-10, octocrylene and fenticlor are completely different. These results suggest that in patients with contact allergy to KP, concomitant positive reactions to cinnamyl alcohol are due to cross-sensitization, whereas simultaneous allergic reactions to fenticlor, octocrylene and benzophenone-10 should be regarded as co-sensitizations.

    ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) is a Flagship Project financed by the Italian Ministry of Education, University and Research, and led by INAF, the Italian National Institute of Astrophysics. The main goals of the ASTRI project are the realization of an end-to-end prototype of a Small Size Telescope (SST) for the Cherenkov Telescope Array (CTA) in a dual- mirror configuration (SST-2M) and, subsequently, of a mini-array comprising seven SST-2M telescopes. The mini-array will be placed at the final CTA Southern Site, which will be part of the CTA seed array, around which the whole CTA observatory will be developed. The Mini-Array Software System (MASS) will provide a comprehensive set of tools to prepare an observing proposal, to perform the observations specified therein (monitoring and controlling all the hardware components of each telescope), to analyze the acquired data online and to store/retrieve all the data products to/from the archive. Here we present the main features of the MASS and its first version, to be tested on the ASTRI SST-2M prototype that will be installed at the INAF observing station located at Serra La Nave on Mount Etna in Sicily.

    ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) is a flagship project of the Italian Ministry of Research and led by the Italian National Institute of Astrophysics (INAF). One of its aims is to develop, within the Cherenkov Telescope Array (CTA) framework, an end-to-end small-sized telescope prototype in a dual-mirror configuration (SST-2M) in order to investigate the energy range E ~ 1-100 TeV. A long-term goal of the ASTRI program is the production of an ASTRI/CTA mini-array composed of seven SST-2M telescopes. The prototype, named ASTRI SST-2M, is seen as a standalone system that needs only network and power connections to work. The software system that is being developed to control the prototype is the base for the Mini-Array Software System (MASS), which has the task to make possible the operation of both the ASTRI SST-2M prototype and the ASTRI/CTA mini-array. The scope of this contribution is to give an overview of the hardware and software architecture adopted for the ASTRI SST- 2M prototype, showing how to apply state of the art industrial technologies to telescope control and monitoring systems.

    We present simulations of the very high energy (VHE) gamma-ray light curve of the Crab pulsar as observed by the Cherenkov Telescope Array (CTA). The CTA pulse profile of the Crab pulsar is simulated with the specific goal of determining the accuracy of the position of the interpulse. We fit the pulse shape obtained by the Major Atmospheric Gamma-Ray Imaging Cherenkov (MAGIC) telescope with a three-Gaussian template and rescale it to account for the different CTA instrumental and observational configurations. Simulations are performed for different configurations of CTA and for the ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) mini-array. The northern CTA configuration will provide an improvement of a factor of ˜3 in accuracy with an observing time comparable to that of MAGIC (73 h). Unless the VHE spectrum above 1 TeV behaves differently from what we presently know, unreasonably long observing times are required for a significant detection of the pulsations of the Crab pulsar with the high-energy-range sub-arrays. We also found that an independent VHE timing analysis is feasible with Large Size Telescopes. CTA will provide a significant improvement in determining the VHE pulse shape parameters necessary to constrain theoretical models of the gamma-ray emission of the Crab pulsar. One of such parameters is the shift in phase between peaks in the pulse profile at VHE and in other energy bands that, if detected, may point to different locations of the emission regions.

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

    According to a teaching of the Prophet Muhammad, "the quest for knowledge is the duty of each Muslim, male or female", where knowledge is meant as the discovery of the real value of things and of oneself in relationship with the world in which God has placed us. This universal dimension of knowledge is in fact a wealth of wisdom of the traditional doctrine naturally linked to the cultural and spiritual heritage of every human being and every believer of every faith. It allows for the respect of internal and external differences as positive elements of the cultural and spiritual heritage of mankind. In this sense, intercultural and interfaith education plays a fundamental role and fits naturally within the Islamic religious education framework. The author of this article is Vice-President and Imam of the Islamic Religious Community in Italy (Comunità Religiosa Islamica [COREIS] Italiana), an organisation which has been providing teachers and students with training on Islam and interfaith dialogue for almost twenty years with the support of the regional and national offices of the Italian Ministry of Public Education. Referring to existing interreligious and intercultural societies such as Azerbaijan, and a number of successful initiatives and projects, several of which COREIS is involved in, he demonstrates how interfaith education can effectively contribute to preventing the diffusion of anti-Semitism, Islamophobia and radicalism.

    US diagnostic equipments are widely diffused in Italy but, in spite of recommendations (e.g. ISPESL-Ministry of Health (1999) and SIRM (Società Italiana di Radiologia Medica, 2004), US quality controls are restricted to only a few public sanitary structure and a national (or even regional) quality assurance program for testing the performances of the US equipments is still missing. A joint Research Centre among the three Piedmontese Universities and INRIM, partially funded by Regione Piemonte, has been established in 2009 as Reference Centre for Medical Ultrasounds (CRUM). In addition to research, development and training tasks, the Centre aims at the local diffusion of the quality assurance in clinical US equipments. According to data from the Ministry of Health (2006), around 7 % of the Italian US diagnostic equipments (946 over 13526) are located in Piedmont: mostly (75.6%) in public hospitals, 9.3 % in conventionated hospitals, 4.3% in public and 10.8% in private territorial structures. The goal is the provision of a regional database, which progressively includes data related to acceptance test, status and QC tests and maintenance, in order to drive equipment turnover and carefully monitoring the overall equipment efficiency. Moreover, facilities are available at CRUM for monitoring both beam geometry and acoustic power and performing quantitative assessment of the delivered energy intensity.

    Animal diseases impact food supplies, trade and commerce, and human health and well-being in every part of the world. Outbreaks draw the attention of those in agriculture, regulatory agencies, and government, as well as the general public. This was demonstrated by the 2000-2001 foot and mouth disease (FMD) outbreaks that occurred in Europe, South America, Asia and Africa and by the recent increased occurrence of emerging diseases transmitted from animals to humans. Examples of these emerging zoonotic diseases are highly pathogenic avian influenza, bovine spongiform encephalopathy, West Nile virus and severe acute respiratory syndrome. There is also the risk of well-known and preventable zoonotic diseases, such as rabies, brucellosis, leishmaniasis, and echinococcosis/hydatidosis, in certain countries; these diseases have a high morbidity with the potential for a very high mortality. Animal agriculturalists should have a global disease awareness of disease risks and develop plans of action to deal with them; in order to better respond to these diseases, they should develop the skills and competencies in politics, media interactions, and community engagement. This issue of Veterinaria Italiana presents information on the risk of animal diseases; their impact on animals and humans at the international, national, industry, and societal levels; and the responses to them. In addition, specific information is provided on national and international disease monitoring, surveillance and reporting, the risk of spread of disease by bioterrorism and on import risk analysis.

    The purpose of the study was to determine if abdomen/pelvis computed tomography (CT) can be safety omitted in the initial staging of a subgroup of children affected by Hodgkin Lymphoma (HL). Every participating center of A.I.E.O.P (Associazione Italiana di Ematologia ed Oncologia Pediatrica) sent local staging reports of 18F-fluorodeoxyglucose positron emission tomography (PET) and abdominal ultrasound (US) along with digital images of staging abdomen/pelvis CT to the investigation center where the CT scans were evaluated by an experienced pediatric radiologist. The local radiologist who performed the US was unaware of local CT and PET reports (both carried out after US), and the reviewer radiologist examining the CT images was unaware of local US, PET and CT reports. A new abdominal staging of 123 patients performed on the basis of local US report, local PET report, and centralized CT report was then compared to a simpler staging based on local US and PET. No additional lesion was discovered by CT in patients with abdomen/pelvis negativity in both US and PET or isolated spleen positivity in US (or US and PET), and so it seems that in the initial staging, abdomen/pelvis CT can be safety omitted in about 1/2 to 2/3 of children diagnosed with HL.

    Two species of Melissa are currently present in Sardinia: Melissa officinalis L. and Melissa romana Mill. Our research can only count on a few supported evidences (as reported in Flora Italiana and Moris) and some notes on new stations in Sardinia that give us some information about morphology, distribution, bioecological, and ethnobotanical characteristics of both species. In this paper, we present the results of the research about morphological aspects of M. romana vs. M. officinalis, and their essential oils in different stations at different phenological periods. Moreover, we compared the essential oil of M. romana with the one obtained from M. officinalis growing in the few naturalized stations still present in Sardinia. The most evident morphological differences between the two entities are the long-stalked capitate glandular trichomes, shorts and inclined capitate trichomes, and peltate hairs. The chemical composition of essential oil presents several significant differences between the species. In fact, oils show that in none of the phenological stages, M. romana recalls in its composition M. officinalis. Major distinctions are also evident between dry and fresh plants, and among essential oils distilled in different seasons.

    Aim To briefly review history, structure, past events and future projects of AIRO (Associazione Italiana Radioterapia Oncologica) young group (AIRO Giovani), focusing on its specific commitment to multidisciplnary networking among junior clinical oncologists at a national and international level. Background AIRO Giovani is a part of AIRO composed by members under 40 years old. Its main activities are scientific and educational meetings dedicated to young Italian radiation oncologists and collaborative research projects. Materials and Methods AIRO Giovani structure, events organized and supported by AIRO giovani as well as scientific activities are here reported from its creation in 2007 up to current days. Results AIRO Giovani group was able to create a consolidated network between Italian junior radiation oncologists, while opening the possibility to collaborate with junior groups of other national scientific societies in the field of oncology and with ESTRO young members. Scientific projects carried out by the group have been successful and will be further implemented in next years. Conclusions AIRO Giovani is still in its infancy, but its early positive experience supports the creation and development of young groups within national radiation oncology societies. PMID:24669305

    Thromboembolic complications represent one of the most important cause of morbidity and mortality in cancer patients. Although several data have been published demonstrating the strong association between cancer and venous thromboembolism (VTE), there is poor perception, among oncologists, of the level of risk of thrombosis and of relevance of managing VTE in these patients. The Associazione Italiana di Oncologia Medica (AIOM) has provided some recommendations to direct clinical practice according to evidence-based data concerning cancer and VTE. In fact, we conducted an extensive literature review (1996-2005) to produce evidence-based recommendations to improve perceptions of the magnitude of this risk among Italian medical and surgical oncologists and alert on the new approaches to prophylaxis and treatment of VTE in cancer patients. Levels of evidence are given according to a five-point rating system, and similarly for each key recommendation a five-point rating system suggests if the evidence is strong and indicate that the benefits do, or do not, outweigh risks and burden.

    Background The fast growing demand and the shortage of resources are pushing toward more efficient models of survivorship care delivery. The Associazione Italiana di Oncologia Medica (AIOM) established an interdisciplinary working group with the purpose of promoting organizational improvements at the national level. A survey aimed at assessing attitudes and feelings of oncologists was considered preliminary to further initiatives. Methods A 25-item questionnaire, sent to the mailing list of the Society, explored the following issues on the practice of breast and colorectal cancer patients' follow up: 1) organization; 2) clinical features; 3) feelings about the different meanings of follow-up. Results Ninety-one oncologists of 160 institutions (57%) answered to the questionnaire. Although follow up is considered a distinct oncological activity in 68%, a fully shared organization between specialists is not common and communications with Primary Care Physicians are not structured in the majority of the cases. Fifty-five and 30% of the oncologists follow breast and colorectal cancer patients indefinitely. In case of discharge a survivorship care plan is delivered in only 9%. The majority of respondents do not hold a role of follow up in mortality reduction. Conclusions Although survivorship care represents a significant part of the oncologists' workload, an “oncology-centered” model is largely adopted and established care pathways are still incomplete. Survivorship care needs to be put at the center of an educational policy and of a widespread organizational effort, directed at improving appropriateness and quality. PMID:24983237

    Costruito per chiara volontà del papa 70 anni dopo il caso Galileo, lo Gnomone Clementino è un grande telescopio solare che non fa uso di lenti a 92 anni dall’invenzione del cannocchiale. Queste due caratteristiche basterebbero da sole a giustificare l’interesse verso questo strumento. L’astronomia meridiana è alla base dell’astrometria e dell’astrofisica moderna. Lo Gnomone Clementino sta oggi all’astronomia, come il veliero “Amerigo Vespucci” sta alla Marina Italiana. E’ possibile svolgere ogni genere di osservazione e studio su questo strumento, e dal 2002 vi tengo lezioni teorico-pratiche del corso di Storia dell’Astronomia e La Terra nel Sistema Solare della Sapienza, Università di Roma, Facoltà di Lettere e Filosofia. Questo testo aggiunge alcuni tasselli alla ricerca storica sulla meridiana, appoggiandosi, com’è naturale, sulle spalle di giganti che mi hanno preceduto in questi studi. In particolare la misura dell’azimut della meridiana, ed il suo inquadramento tra gli strumenti simili ed alcuni studi di astrometria sui dati del 1701-1703 di Bianchini, che sono apparsi fin’ora soltanto su riviste specializzate ed in Inglese vengono qui proposti in Italiano e semplificati, per valorizzare sempre più questa straordinaria opera d’arte e di scienza.

    High-dose methotrexate (MTX) is a key component of most treatment protocols for childhood and adolescent non-Hodgkin lymphoma (NHL). Recent studies have suggested that the toxicity of antifolate drugs, such as MTX, is affected by inherited single nucleotide polymorphisms (SNPs) in folate metabolizing genes. The aim of our study was to investigate the potential influence of the C677T and A1298C genetic variants of the methylenetetrahydrofolate reductase (MTHFR) gene on the clinical toxicity and efficacy of MTX in pediatric patients with NHL (n = 95) treated with therapeutic protocols Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP) LNH-97 and EURO LB-02. We demonstrated that patients with the 677T genotype had an approximately six-fold greater risk of developing hematological toxicity compared with wild-type carriers, especially in the 1 g/m(2) treatment group (p = 0.01). Moreover, we identified a correlation between the risk of relapse and the T genotype: T carriers had reduced disease-free survival compared with wild-type patients (67% vs. 100%). Our data suggest a pharmacogenetic influence on the adverse effects of high-dose MTX in the 1 g/m(2) treatment group.

    This paper, summarizing the March 2012 presentation at the second international workshop of the Canadian Task Force on Adolescents and Young Adults with Cancer, describes the situation in Italy concerning the inadequate access to optimal cancer services for adolescents, and the need to improve the quality of care for these patients while investing in more research on the diseases that afflict them. National actions to bridge the gap in care and implement specific programs tailored to these patients arose from the pediatric oncology community. These actions include creation of the national Committee on Adolescents of the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP), founded with the mission of ensuring that Italian adolescents with cancer have prompt, adequate, and equitable access to the best care to optimize their treatment outcome and quality of life. Also developed was the Youth Project of the pediatric oncology unit at the Istituto Nazionale Tumori in Milan, which is currently dedicated to adolescents aged 15-19 years old and may eventually serve young adults up to the age of 25 that are affected by pediatric-type tumors.

    We evaluated the outcome of 482 children with acute myeloid leukemia (AML) enrolled in the Associazione Italiana di Ematologia e Oncologia Pediatrica AML 2002/01 trial. Treatment was stratified according to risk group; hematopoietic stem cell transplantation (HSCT) was used in high-risk (HR) children. Patients with core binding factor leukemia achieving complete remission (CR) after the first induction course were considered standard risk (SR; 99 patients), whereas the others (n = 383) were assigned to the HR group. Allogeneic (ALLO) or autologous (AUTO) HSCT was employed, respectively, in 141 and 102 HR patients after consolidation therapy. CR, early death, and induction failure rates were 87%, 3%, and 10%, respectively. Relapse occurred in 24% of patients achieving CR. The 8-year overall survival (OS), event-free survival (EFS), and disease-free survival (DFS) were 68%, 55%, and 63%, respectively. OS, EFS, and DFS for SR and HR patients were 83%, 63%, and 66% and 64%, 53%, and 62%. DFS was 63% and 73% for HR patients given AUTO-HSCT and ALLO-HSCT, respectively. In multivariate analysis, risk group, white blood cell >100 × 10(9)/L at diagnosis, and monosomal karyotype predicted poorer EFS. Risk-oriented treatment and broad use of HSCT result in a long-term EFS comparing favorably with previously published studies on childhood AML.

    Nucleophosmin (NPM) is a nucleocytoplasmic shuttling protein involved in leukemia-associated chromosomal translocations, and it regulates the alternate reading frame (ARF)-p53 tumor-suppressor pathway. Recently, it has been demonstrated that mutations of the NPM1 gene alter the protein at its C-terminal, causing its cytoplasmic localization. Cytoplasmic NPM was detected in 35% of adult patients with primary non-French-American-British (FAB) classification M3 acute myeloid leukemia (AML), associated mainly with normal karyotype. We evaluated the prevalence of the NPM1 gene mutation in non-M3 childhood AML patients enrolled in the ongoing Associazione Italiana di Ematologia e Oncologia Pediatrica (AIEOP-AML02) protocol in Italy. NPM1 mutations were found in 7 (6.5%) of 107 successfully analyzed patients. NPM1-mutated patients carried a normal karyotype (7/26, 27.1%) and were older in age. Thus, the NPM1 mutation is a frequent abnormality in AML patients without known genetic marker; the mutation may represent a new target to monitor minimal residual disease in AML and a potential candidate for alternative and targeted treatments.

    Since 1982, four consecutive studies on childhood acute myeloid leukaemia (AML) (namely LAM-82, -87, -87M and -92) have been conducted in Italy by the Associazione Italiana di Ematologia e Oncologia Pediatrica (AIEOP) group. The induction therapy of the first three studies consisted of daunorubicin and cytarabine structured in a 3+7 backbone. In the most recent protocol (LAM92), patients received two induction courses including idarubicin, cytarabine and etoposide. Patients with acute promyelocytic leukaemia (20% of diagnoses) were included in LAM-87 and 87M studies. Postremissional therapy significantly changed over time, with an ever-increasing role given to stem cell transplantation (SCT). The long-term outcome of patients enrolled in the LAM-82, 87 and 87M studies was comparable, whereas that of children treated according to LAM-92 study was significantly better (P<0.005). Either allogeneic or autologous SCT was employed as consolidation therapy in more than 75% of cases enrolled in this latter study. Patients enrolled in the LAM-92 study were stratified in standard and high-risk groups with different outcome (67 vs 47%, respectively, P=0.04). Altogether, the results obtained in these four studies have permitted a progressive refinement of treatment, contributing to the structure of the ongoing LAM-2002 protocol that stratifies patients according to the presence of definite genetic anomalies and response to induction therapy.

    Somatic mutations in PTPN11, the gene encoding the transducer SHP-2, have emerged as a novel class of lesions that upregulate RAS signalling and contribute to leukaemogenesis. In a recent study of 69 children and adolescents with de novo acute myeloid leukaemia (AML), we documented a non-random distribution of PTPN11 mutations among French-American-British (FAB) subtypes. Lesions were restricted to FAB-M5 cases, where they were relatively common (four of 12 cases). Here, we report on the results of a molecular screening performed on 181 additional unselected patients, enrolled in participating institutions of the Associazione Italiana Ematologia Oncologia Pediatrica-AML Study Group, to provide a more accurate picture of the prevalence, spectrum and distribution of PTPN11 mutations in childhood AML and to investigate their clinical relevance. We concluded that PTPN11 defects do not represent a frequent event in this heterogeneous group of malignancies (4.4%), although they recur in a considerable percentage of patients with FAB-M5 (18%). PTPN11 lesions rarely occur in other subtypes. Within the FAB-M5 group no clear association of PTPN11 mutations with any clinical variable was evident. Nearly two third of the patients with this subtype were found to harbour an activating mutation in PTPN11, NRAS, KRAS2 or FLT3.

    Children with acute lymphoblastic leukemia (ALL) and high minimal residual disease (MRD) levels after initial chemotherapy have a poor clinical outcome. In this prospective, single arm, Phase 2 trial, 111 Dutch and Australian children aged 1-18 years with newly diagnosed, t(9;22)-negative ALL, were identified among 1041 consecutively enrolled patients as high risk (HR) based on clinical features or high MRD. The HR cohort received the AIEOP-BFM (Associazione Italiana di Ematologia ed Oncologia Pediatrica (Italy)-Berlin-Frankfurt-Münster ALL Study Group) 2000 ALL Protocol I, then three novel HR chemotherapy blocks, followed by allogeneic transplant or chemotherapy. Of the 111 HR patients, 91 began HR treatment blocks, while 79 completed the protocol. There were 3 remission failures, 12 relapses, 7 toxic deaths in remission and 10 patients who changed protocol due to toxicity or clinician/parent preference. For the 111 HR patients, 5-year event-free survival (EFS) was 66.8% (±5.5) and overall survival (OS) was 75.6% (±4.3). The 30 patients treated as HR solely on the basis of high MRD levels had a 5-year EFS of 63% (±9.4%). All patients experienced grade 3 or 4 toxicities during HR block therapy. Although cure rates were improved compared with previous studies, high treatment toxicity suggested that novel agents are needed to achieve further improvement.

    The Associazione Italiana di Ematologia Oncologia Pediatrica and the Berlin-Frankfurt-Münster Acute Lymphoblastic Leukemia (AIEOP-BFM ALL 2000) study has for the first time introduced standardized quantitative assessment of minimal residual disease (MRD) based on immunoglobulin and T-cell receptor gene rearrangements as polymerase chain reaction targets (PCR-MRD), at 2 time points (TPs), to stratify patients in a large prospective study. Patients with precursor B (pB) ALL (n = 3184) were considered MRD standard risk (MRD-SR) if MRD was already negative at day 33 (analyzed by 2 markers, with a sensitivity of at least 10(-4)); MRD high risk (MRD-HR) if 10(-3) or more at day 78 and MRD intermediate risk (MRD-IR): others. MRD-SR patients were 42% (1348): 5-year event-free survival (EFS, standard error) is 92.3% (0.9). Fifty-two percent (1647) were MRD-IR: EFS 77.6% (1.3). Six percent of patients (189) were MRD-HR: EFS 50.1% (4.1; P < .001). PCR-MRD discriminated prognosis even on top of white blood cell count, age, early response to prednisone, and genotype. MRD response detected by sensitive quantitative PCR at 2 predefined TPs is highly predictive for relapse in childhood pB-ALL. The study is registered at http://clinicaltrials.gov: NCT00430118 for BFM and NCT00613457 for AIEOP.

    Possible bifurcation within the solution set to the Grad-Shafranov equation (GSE) is investigated. This study develops the recently suggested approach [1], which treats transport barrier formation in a tokamak as a bifurcation of plasma equilibrium. That approach presumes that plasma pressure and electric current are subject to bifurcation rather than the electric field, which only serves as a trigger of the transition to new equilibrium state. It was E. Solano, who pointed out a possibility of such a bifurcation in the frame of GSE [2]. In this report, we demonstrate the examples of bifurcations in one-parametric solution set for a tokamak with nested magnetic surfaces. Mathematically, there are two different solutions corresponding to the same parameter value and satisfying the same or very close boundary conditions, separated by a separatrix. Such a solution behaviour is confirmed by 2D numerical calculations made with standard GSE solver. [1]. V.I. Ilgisonis, Yu.I.

    The EuroPlaNet information service provides access to lists of researchers, laboratories and data archives relevant to many aspects of planetary and space physics. Information can be accessed through EuroPlaNet website or, for advanced searches, via web-services available at the different thematic nodes. The goal of IDIS is to provide easy-to-use access to resources like people, laboratories, modeling activities and data archives related to planetary sciences. The development of IDIS is an international effort started under the European Commission's 6th Framework Programme and which will expand its capabilities during the 7th Framework Programme, as part of the Capacities Specific Programme/Research Infrastructures. IDIS is complemented by a set of other EuroPlaNet web-services maintained under the responsibility of separate institutions. Each activity maintains its own web-portal with cross-links pointing to the other elements of EuroPlaNet. General access is provided via the EuroPlaNet Homepage. IDIS is not a repository of original data but rather supports the access to various data sources. The final goal of IDIS is to provide Virtual Observatory tools for the access to data from laboratory measurements and ground- and spaced-based observations to modeling results, allowing the combination of as divergent data sources as feasible. IDIS is built around four scientific nodes located in different European countries. Each node deals with a subset of the disciplines related to planetary sciences and, working in cooperation with international experts in these fields, provides a wealth of information to the international planetary science community. The EuroPlaNet IDIS thematic node "Small Bodies and Dust Node" is hosted by the Istituto di Fisica dello Spazio Interplanetario and is established in close cooperation with the Istituto di Astrofisica Spaziale. Both these institutes are part of the Istituto Nazionale di Astrofisica (INAF). The IDIS Small Bodies and Dust

  19. A methodology for system-of-systems design in support of the engineering team

    Space missions have experienced a trend of increasing complexity in the last decades, resulting in the design of very complex systems formed by many elements and sub-elements working together to meet the requirements. In a classical approach, especially in a company environment, the two steps of design-space exploration and optimization are usually performed by experts inferring on major phenomena, making assumptions and doing some trial-and-error runs on the available mathematical models. This is done especially in the very early design phases where most of the costs are locked-in. With the objective of supporting the engineering team and the decision-makers during the design of complex systems, the authors developed a modelling framework for a particular category of complex, coupled space systems called System-of-Systems. Once modelled, the System-of-Systems is solved using a computationally cheap parametric methodology, named the mixed-hypercube approach, based on the utilization of a particular type of fractional factorial design-of-experiments, and analysis of the results via global sensitivity analysis and response surfaces. As an applicative example, a system-of-systems of a hypothetical human space exploration scenario for the support of a manned lunar base is presented. The results demonstrate that using the mixed-hypercube to sample the design space, an optimal solution is reached with a limited computational effort, providing support to the engineering team and decision makers thanks to sensitivity and robustness information. The analysis of the system-of-systems model that was implemented shows that the logistic support of a human outpost on the Moon for 15 years is still feasible with currently available launcher classes. The results presented in this paper have been obtained in cooperation with Thales Alenia Space—Italy, in the framework of a regional programme called STEPS.

    The project STEPS (Sistemi e Tecnologie per l'EsPlorazione Spaziale) is a joint development of technologies and systems for Space Exploration supported by Regione Piemonte, the European Regional Development Fund (E.R.D.F.) 2007-2013, Thales Alenia Space Italia (TAS-I), SMEs, Universities and public Research Centres belonging to the network "Comitato Distretto Aerospaziale del Piemonte" the Piedmont Aerospace District (PAD) in Italy. The project first part terminated in May 2012 with a final demonstration event that summarizes the technological results of research activities carried-out during a period the three years and half. The project developed virtual and hardware demonstrators for a range of technologies for the descent, soft landing and surface mobility of robotic and manned equipment for Moon and Mars exploration. The two key hardware demonstrators—a Mars Lander and a Lunar Rover—fit in a context of international cooperation for the exploration of Moon and Mars, as envisaged by Space Agencies worldwide. The STEPS project included also the development and utilization of a system of laboratories equipped for technology validation, teleoperations, concurrent design environments, and virtual reality simulation of the Exploration Systems in typical Moon and Mars environments. This paper presents the reached results in several technology domains like: vision-based GNC for the last portion of Mars Entry, Descent and Landing sequence, Hazard avoidance and complete spacecraft autonomy; Autonomous Rover Navigation, based on the determination of the terrain morphology by a stereo camera; Mobility and Mechanisms providing an Integrated Ground Mobility System, Rendezvous and Docking equipment, and protection from Environment effects; innovative Structures such as Inflatable, Smart and Multifunction Structures, an Active Shock Absorber for safe landing, balance restoring and walking; Composite materials Modelling and Monitoring; Human-machine interface features of a

    In the occasion of the celebrations for the 150th anniversary of the founding of Italy (1861-2011), it was decided to analyse the artwork "The Italian Flag" (La Bandiera Italiana) created by the artist Fernando Melani (Pistoia, 1907-1985), one of the precursors of the Poor Art artistic movement in Italy. This project is a follow-up to a previous study which was mainly focused on the pigments and dyes found in his home-studio. The main goal of this paper is to identify a correct diagnostic plan, based on the use of a combination of non-invasive and micro-invasive methodologies, in order to determine the state of preservation and define the best conservation procedures for a contemporary artwork. Visible, infrared and infrared false colour images as well as the Fibre Optic Reflectance Spectroscopy (FORS) technique were applied in situ to analyse The Italian Flag. Laser Induced Breakdown Spectroscopy (LIBS), Fourier Transform Infrared (FT-IR) and micro-Raman spectroscopies, Pyrolysis-Gas Chromatography/Mass Spectroscopy (Py-GC/MS), High Performance Liquid Chromatography with Diode Arrays Detection (HPLC-DAD) and Mass Spectrometric Detection (HPLC-ESI-Q-ToF) were all applied to three small samples detached from the three painted (green-blue, white and red-yellow, respectively) areas of the flag. The combination of the data obtained with all these techniques made possible a comprehensive understanding of both the chemical composition and physical behaviour of the materials used by the artist and supported curators in defining the preventive conservation of this artwork.

    The paternal ages of nonfamilial cases of achondroplasia (AC) (n = 78), thanatophoric dysplasia (TD) (n = 64), and osteogenesis imperfecta (OI) (n = 106), were compared with those of matched controls, from an Italian Indagine Policentrica Italiana sulle Malformazioni Congenite and a South American Estudio Colaborativo Latinoamericano de Malformaciones Congénitas series. The degree of paternal age effect on the origin of these dominant mutations differed among the three conditions. Mean paternal age was highly elevated in AC, 36.30 +/- 6.74 years in the IPIMC, and 37.19 +/- 10.53 years in the ECLAMC; less consistently elevated in TD, 33.60 +/- 7.08 years in the IPIMC, and 36.41 +/- 9.38 years in the ECLAMC; and only slightly elevated in OI in the ECLAMC, 31.15 +/- 9.25 years, but not in the IPIMC, 32.26 +/- 6.07 years. Increased maternal age or birth order in these conditions disappeared when corrected for paternal age. Approximately 50% of AC and TD cases, and only 30% of OI cases, were born to fathers above age 35 years. For AC and TD, the increase in relative incidence with paternal age fitted an exponential curve. The variability of paternal age effect in these new mutations could be due, among other reasons, to the high proportion of germ-line mosaicism in OI parents, or to the localization of the AC gene, mapped to the 4p16.3 region, in the neighborhood of an unstable DNA area.

    ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) is a Flagship Project financed by the Italian Ministry of Education, University and Research, and led by INAF, the Italian National Institute of Astrophysics. Within this framework, INAF is currently developing an end-to-end prototype of a Small Size dual-mirror Telescope. In a second phase the ASTRI project foresees the installation of the first elements of the array at CTA southern site, a mini-array of 7 telescopes. The ASTRI Camera DAQ Software is aimed at the Camera data acquisition, storage and display during Camera development as well as during commissioning and operations on the ASTRI SST-2M telescope prototype that will operate at the INAF observing station located at Serra La Nave on the Mount Etna (Sicily). The Camera DAQ configuration and operations will be sequenced either through local operator commands or through remote commands received from the Instrument Controller System that commands and controls the Camera. The Camera DAQ software will acquire data packets through a direct one-way socket connection with the Camera Back End Electronics. In near real time, the data will be stored in both raw and FITS format. The DAQ Quick Look component will allow the operator to display in near real time the Camera data packets. We are developing the DAQ software adopting the iterative and incremental model in order to maximize the software reuse and to implement a system which is easily adaptable to changes. This contribution presents the Camera DAQ Software architecture with particular emphasis on its potential reuse for the ASTRI/CTA mini-array.

    The Cherenkov Telescope Array (CTA) is a worldwide new generation project aimed at realizing an array of a hundred ground based gamma-ray telescopes. ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) is the Italian project whose primary target is the development of an end-to-end prototype, named ASTRI SST-2M, of the CTA small size class of telescopes devoted to investigation of the highest energy region, from 1 to 100 TeV. Next target is the implementation of an ASTRI/CTA mini-array based on seven identical telescopes. Silicon Photo-Multipliers (SiPMs) are the semiconductor photosensor devices designated to constitute the camera detection system at the focal plane of the ASTRI telescopes. SiPM photosensors are suitable for the detection of the Cherenkov flashes, since they are very fast and sensitive to the light in the 300-700nm wavelength spectrum. Their drawbacks compared to the traditional photomultiplier tubes are high dark count rates, after-pulsing and optical cross-talk contributions, and intrinsic gains strongly dependent on temperature. Nonetheless, for a single pixel, the dark count rate is well below the Night Sky Background, the effects of cross-talk and afterpulses are typically lower than 20%, and the gain can be kept stable against temperature variations by means of adequate bias voltage compensation strategies. This work presents and discusses some experimental results from a large set of measurements performed on the SiPM sensors to be used for the ASTRI SST-2M prototype camera and on recently developed detectors demonstrating outstanding performance for the future evolution of the project in the ASTRI/CTA mini-array.

    ASI, the Italian Space Agency, is going to finance a developing of a small satellite platforms production line called PRIMA (Piattaforma Riconfigurabile Italiana Multi-Applicativa) with Alenia Aerospazio partnership as Prime Contractor and sub-contractors preferably chosen within the Italian Space Industries. The main objective of the program is to develop a multi-mission, easily adaptable Platform for LEO orbits, allowing rapid, efficient and low cost bus for applicative and scientific missions. The Italian national space plan foresees for the enf of 2001 the build up of the Skymed/Cosmo constellation as applicative Earth observation program plus a number of small scientific spacecraft with a rate of 2 missions each three years. To fulfil these schedules, the PRIMA platform should complete its development and qualification program in order to be ready for the first unit (protoqualification flight) to interface the first payload (Science or Applicative). The intrinsic modularity of PRIMA should allow it to adapt itself to a large variety of missions in LEO orbits with minor modifications. The design will be conducted in order to get an advanced Platform able to meet a large set of missions, payloads and launcher specifications. The platform will be completed by a ground control centre adapted to the monitoring of PRIMA based satellites. PRIMA thus offers a very attractive alternative to large-scale missions in terms of costs and completion time. The paper will describe the technical aspects of PRIMA Platform, with particular emphasis put onto its flexibility and reconfigurability for different missions. The System and S/S architectures will also be presented and defined in view of selected mission cases. The AIV/AIT aspects will be discussed, with a discussion of the applicability of Globalstar™ approaches, facility and heritage. Finally, a brief overview of PRIMA first applications /SkyMed/COSMO and David) will be given.

    Sommario INTRODUZIONE: La sicurezza nell'uso degli ultrasuoni va sempre considerata in campo ecografico, in quanto gli ultrasuoni sono in grado di indurre effetti biologici potenzialmente dannosi, soprattutto con l'introduzione di nuove tecnologie. SCOPO DELLO STUDIO: Valutare il livello di consapevolezza e di conoscenza dei medici italiani soci SIUMB sulla sicurezza nell'uso dell'ecografia nella pratica clinica. MATERIALI E METODI: Un questionario contenente 11 domande a risposta multipla è stato inviato per e-mail a soci SIUMB (Società Italiana di Ultrasonologia in Medicina e Biologia). Le risposte sono state inserite in un database elettronico ed analizzate statisticamente. RISULTATI: Sono tornati questionari da 105 soci, di età media di 44 anni i cui esami ecografici più frequentemente eseguiti, in aggiunta all'ecografia B-mode standard, erano l'ecoDoppler (74%), l'ecografia con mezzo di contrasto (43%) e l'ecografia pediatrica (43%). Solo il 50–60% conosceva la definizione corretta dell'Indice Meccanico e dell'Indice Termico. Quasi tutti i partecipanti comprendevano gli effetti biologici espressi con Indice Termico, nonostante che solo una minoranza sapesse in quale organo gli effetti biologici, in relazione all'Indice Meccanico, potevano, con più probabilità, verificarsi; analogamente solo una minoranza conosceva l'unità di grandezza per l'Indice Termico. La maggioranza era a conoscenza di come i tessuti del feto siano più suscettibili ai potenziali effetti di quelli adulti. Pochi partecipanti conoscevano le raccomandazioni delle Società Internazionali di Ultrasonologia in campo di sicurezza. CONCLUSIONI: Lo studio ha fatto emergere come sia necessaria una maggior diffusione delle conoscenze sugli effetti biologici degli ultrasuoni tra gli ecografisti italiani.

    Background. Gli ambienti di apprendimento clinico sono definiti come una rete di fattori interagenti nel contesto, in grado di influenzare gli esiti dell’apprendimento degli studenti. La soddisfazione degli studenti è considerata un indicatore del raggiungimento degli esiti dell’apprendimento ed è determinante a partire dalla prima esperienza di tirocinio. Scopo. Analizzare l’esperienza di apprendimento clinico degli studenti infermieri del primo anno di corso dopo il primo tirocinio clinico ed identificare i principali determinanti della soddisfazione degli studenti. Metodo. Lo studio osservazionale è stato realizzato in cinque sedi universitarie italiane del Corso di Laurea in Infermieristica. 420 studenti hanno compilato la versione italiana della “Clinical Learning Environment, Supervision and plus Nurse Teacher (CLES+T) scale” al termine del primo tirocinio clinico. Risultati. I punteggi medi assegnati alle dimensioni della scala variano da 4.02 (clima di apprendimento) a 3.30 (relazione di tutorato). La maggior parte degli studenti è soddisfatto della propria esperienza di tirocinio (75.6%), ma sono emerse differenze in relazione alle diverse sedi di tirocinio clinico. Discussione. I principali determinanti della soddisfazione sono lo stile di leadership del coordinatore infermieristico e l’integrazione teoria-pratica nella relazione fra tutor clinico, universitario e studente. Conclusioni. I risultati dello studio contribuiscono alla comprensione della prima esperienza di tirocinio degli studenti. Tuttavia, sono necessarie ulteriori ricerche per determinare le variabili organizzative specifiche e i modelli tutoriali in grado di aumentare la soddisfazione degli studenti, per sviluppare strategie formative basate sull’integrazione tra tutor universitari e guide di tirocinio.

    Background The modifications of cholesterol metabolism associated with aging are ill-defined. The objective of this study was to define age-associated alterations of the different metabolic pathways controlling cholesterol homeostasis by analyzing circulating sterols. Methods We analyzed serum samples collected from 201 adult (75 male, 126 female) subjects within the epidemiological MICOL study (Multicentrica Italiana Colelitiasi). The age range was 38–79 years; 103 had evidence of gallstones. The concentrations of the different sterols, recognized as markers of the main pathways of cholesterol homeostasis, were analyzed by gas chromatography-mass spectrometry, including lathosterol (synthesis), campesterol and sitosterol (absorption), and 7α-hydroxy-4-cholesten-3-one (degradation to bile acids). Results A significant direct correlation was detected between age and cholesterol levels (r =0.34, P<0.01). The lathosterol/cholesterol ratio was lower in older age quartiles (P<0.05 by analysis of variance), with an inverse correlation between the lathosterol/cholesterol ratio and age (r=−0.32, P<0.01). Such correlation was particularly evident in females. The campesterol/cholesterol and sitosterol/cholesterol ratios were inversely correlated with aging in control, but not in gallstone patients. The levels of 7α-hydroxy-4-cholesten-3-one were not correlated with age. Conclusion These data show a reduction of cholesterol synthesis with aging which is associated with increased circulating cholesterol levels. The finding might be related to a reduced metabolic need for cholesterol in advancing age, leading to a downregulation of the main mechanisms of cholesterol intake in the liver. A different age-related behavior was observed in gallstone-free versus gallstone patients regarding cholesterol absorption. The possible implications in terms of the pharmacological management of hypercholesterolemia in the elderly remain to be defined. PMID:24669190

    In Italy, the crisis of the wool industry triggered the necessity to reconvert the two traditional Merino-derived breeds, Gentile di Puglia and Sopravissana, to meat production, by creating the Merinizzata Italiana. The aim of the present study was to assess the genetic diversity of these three Italian Merino-derived (IMd) breeds by examining the molecular information encoded in the maternally-inherited mitochondrial DNA (mtDNA). A parallel molecular investigation was performed on the putative paternal and maternal breeds, the Merino from Spain and the Appenninica from Italy, respectively, as well as on three unrelated dairy breeds (Sarda and Comisana from Italy, and Lacaune from France). Firstly, the mtDNA control region of 291 samples was analyzed. When comparing the overall genetic distances among the eight stocks, the three IMd breeds clustered together close to the Appenninica, thus confirming its parental role. Among the 90 IMd samples, 82 different haplotypes were observed, almost all belonging to haplogroup B, and only one to A. For 23 mtDNAs, including nine IMd, the analysis was then brought to the level of entire mitogenomes. Three distinct sub-haplogroups within B were found to encompass the IMd samples, with one clade (B1a2a1) apparently restricted to those sheep. Thus, despite experiencing a drastic reduction in number (mainly due to changes in breeding practices driven by the economy), the IMd breeds still represent a reservoir of distinctive mitochondrial variants, which could potentially contribute to the development of conservation and management programs of Italian sheep breeds.

    One of the most important challenges for embodied and grounded theories of cognition concerns the representation of abstract concepts, such as “freedom.” Many embodied theories of abstract concepts have been proposed. Some proposals stress the similarities between concrete and abstract concepts showing that they are both grounded in perception and action system while other emphasize their difference favoring a multiple representation view. An influential view proposes that abstract concepts are mapped to concrete ones through metaphors. Furthermore, some theories underline the fact that abstract concepts are grounded in specific contents, as situations, introspective states, emotions. These approaches are not necessarily mutually exclusive, since it is possible that they can account for different subsets of abstract concepts and words. One novel and fruitful way to understand the way in which abstract concepts are represented is to analyze how sign languages encode concepts into signs. In the present paper we will discuss these theoretical issues mostly relying on examples taken from Italian Sign Language (LIS, Lingua dei Segni Italiana), the visual-gestural language used within the Italian Deaf community. We will verify whether and to what extent LIS signs provide evidence favoring the different theories of abstract concepts. In analyzing signs we will distinguish between direct forms of involvement of the body and forms in which concepts are grounded differently, for example relying on linguistic experience. In dealing with the LIS evidence, we will consider the possibility that different abstract concepts are represented using different levels of embodiment. The collected evidence will help us to discuss whether a unitary embodied theory of abstract concepts is possible or whether the different theoretical proposals can account for different aspects of their representation.

    Introduzione. Attualmente sono pochi gli studi che indagano la capacità empatica nella popolazione infermieristica. Obiettivo di questo studio è analizzare la capacità empatica degli infermieri che prestano servizio in area medica in relazione a genere, età, formazione e anzianità di servizio. Materiali e metodi. Lo studio è di tipo descrittivo-osservazionale, su un campione di 60 infermieri. Lo strumento utilizzato per la valutazione dell’empatia è la scala di valutazione JSPE (versione HP) costituita da 20 item, in cui gli intervistati indicano il loro accordo o disaccordo con una scala Likert a 7 punti. Il range di valori possibili è da 20 a 140: il punteggio più alto corrisponde a una maggiore capacità empatica. Il questionario ha dimostrato la validità e l'affidabilità della versione italiana del JSPE con un coefficiente alfa di Cronbach di 0,85. Il punteggio Il livello di significatività statistica accettato è pari a P ≤ 0,05. Risultati. La media della capacità empatica dei professionisti intervistati è risultata di 104/140. Dai dati analizzati, emerge che con l’aumentare degli anni di servizio alla professione si verifica una diminuzione dell’empatia così come il permanere nello stesso reparto provoca una diminuzione empatica. Inoltre è emersa una maggiore empatia degli infermieri della neurologia rispetto alla medicina generale. Conclusioni. Lo studio evidenzia come i professionisti abbiano necessità di incrementare la capacità empatica soprattutto col trascorrere degli anni di esercizio alla professione. Probabilmente come meccanismo di difesa, il professionista tende a proteggersi dal coinvolgimento emotivo, favorendo le attività di natura più tecnico-gestuale, piuttosto che relazionale.

    The paternal ages of nonfamilial cases of achondroplasia (AC) (n = 78), thanatophoric dysplasia (TD) (n = 64), and osteogenesis imperfecta (OI) (n = 106), were compared with those of matched controls, from an Italian Indagine Policentrica Italiana sulle Malformazioni Congenite (IPIMC) and a South American Estudio Colaborativo Latinoamericano de Malformaciones Congenitas (ECLAMC) series. The degree of paternal age effect on the origin of these dominant mutations differed among the three conditions. Mean paternal age was highly elevated in AC, 36.30 {plus_minus} 6.74 years in the IPIMC, and 37.19 {plus_minus} 10.53 years in the ECLAMC; less consistently elevated in TD, 33.60 {plus_minus} 7.08 years in the IPIMC, and 36.41 {plus_minus} 9.38 years in the ECLAMC; and only slightly elevated in OI in the ECLAMC, 31.15 {plus_minus} 9.25 years, but not in the IPIMC, 32.26 {plus_minus} 6.07 years. Increased maternal age or birth order in these conditions disappeared when corrected for paternal age. Approximately 50% of AC and TD cases, and only 30% of OI cases, were born to fathers above age 35 years. For AC and TD, the increase in relative incidence with paternal age fitted an exponential curve. The variability of paternal age effect in these new mutations could be due, among other reasons, to the high proportion of germ-line mosaicism in OI parents, or to the localization of the AC gene, mapped to the 4p16.3 region, in the neighborhood of an unstable DNA area. 28 refs., 1 fig., 6 tabs.

    A capillary GC-flame ionization detection (FID) method to determine volatile compounds (ethyl acetate, 1,1-diethoxyethane, methyl alcohol, 1-propanol, 2-methyl-1-propanol, 2-methyl-1-butanol, 3-methyl-1-butanol, 1-butanol, and 2-butanol) in wine was investigated in terms of calculation of detection limits and calibration method. The main objectives were: (1) calculation of regression coefficient parameters by ordinary least-squares (OLS) and bivariate least-squares (BLS) regression models, taking into account errors in both axes; (2) estimation of linear dynamic range (LDR) according to International Conference on Harmonization recommendations; (3) performance evaluation of a method by using three different internal standards (ISs) such as acetonitrile, acetone, and 1-pentanol; (4) evaluation of LODs according to the U.S. Environmental Protection Agency (EPA) 3sigma approach and the Hubaux-Vos (H-V) method; (5) application of H-V theory to a gas chromatographic analytical method and to a food matrix; and (6) accuracy assessment of the method relative to methyl alcohol content through a Unione Italiana Vini (UIV) interlaboratory proficiency test. Calibration curves calculated via BLS and OLS show similar slopes, while intercepts are closer to zero in the first case, independent of the chosen IS. The studied ISs show a substantially equivalent behavior, even though the IS closer to the analyte retention time seems to be more appropriate in terms of LDR and LOD. Results indicate an underestimation of LODs using the EPA 3sigma approach instead of the more realistic H-V method, both with OLS and BLS regression models. Methanol contents compared with UIV average values indicate recovery between 90 and 110%.

    Children with Philadelphia-chromosome-positive (Ph+) acute lymphoblastic leukaemia (ALL) represent a subgroup at very high risk for treatment failure, despite intensive chemotherapy. However, recent retrospective studies showed that Ph+ childhood ALL is a heterogeneous disease with regard to treatment response. We have prospectively monitored, by reverse transcription polymerase chain reaction (RT-PCR) during follow-up, the presence of the BCR/ABL fusion transcript in Ph+ ALL children diagnosed in the Italian multicentre Associazione Italiana Ematologia Oncologia Pediatrica ALL-AIEOP-95 therapy protocol. To our knowledge, this is the first report on the evaluation of minimal residual disease (MRD) in childhood Ph+ ALL prospectively enrolled in an intensive, Berlin-Frankfurt-Munster (BFM)-type treatment protocol. Twenty-seven of 36 (75.0%) Ph+ patients consecutively enrolled into the high-risk group of the AIEOP-ALL protocol between May 1995 and October 1999 were successfully analysed. Twenty were good responders to the pre-phase of prednisone/intrathecal methotrexate treatment (PGR) and seven were poor responders (PPR). Within the PPR group, the RT-PCR monitoring constantly showed positivity for the BCR/ABL fusion transcript and all the patients died of disease progression. In contrast, highly sensitive qualitative RT-PCR monitoring revealed heterogeneity within the PGR group of Ph+ childhood ALL patients. Three different subgroups could be defined, according to the clearance of Ph+ cells within the first 5 months of treatment. This provides useful information on the capability of chemotherapy to reduce the leukaemic clone, with prognostic implications.

    In the present study the authors evaluated therapy-related long-term adverse effects and physical activity in a cohort of long-term survivors of childhood acute lymphoblastic leukemia (ALL), diagnosed in their center between March 1991 and August 2000, treated according to the AIEOP (Associazione Italiana di Ematologia e Oncologia Pediatrica) ALL 91 or 95 study protocol and regularly seen in the authors' long-term follow-up unit. The authors analyzed the long-term sequelae of major body systems in this cohort of subjects and administered an "ad hoc" questionnaire concerning sport. The authors found that 70 patients out of 102 (68.5%) showed no late effects, 10% presented only instrumental or neuropsychological test abnormalities, and 21.5% had 1 or more clinical late sequelae. None of the evidenced late effects represented a contraindication to do physical activity. Sixty-one percent of survivors do physical activity, most of them regularly. Sixty-one percent of males and 18.5% of females (P < .005) do competitive sport (sports rates are similar to those of the general age-matched population). Nearly all subjects spontaneously choose to do sport and think physical exercise is an important and useful resource for their health. The authors conclude that the more recent therapy regimens for leukemia treatment, excluding bone marrow transplantation, do not seem to cause such late effects as to prevent survivors from doing sport. Therefore, in the care of ALL survivors, physical activity is not only not contraindicated, but should also be promoted as much as possible. The development of specific educational programs is warranted as part of the care of cancer survivors.

    Paediatric patients with acute myeloid leukaemia (AML) who fail induction due to primary resistance to chemotherapy account for a significant proportion of cases and have a particularly dismal prognosis. We report the clinical and biological data, and final outcome of 48 paediatric patients with primary-resistant AML enrolled in the Associazione Italiana di Ematologia e Oncologia Pediatrica AML 2002/01 clinical trial. These patients had a significantly higher white blood cell count at diagnosis compared to other AML patients. Cytogenetic and molecular features did not differ between patients with primary induction failure and patients allocated to the high-risk group. For the whole patient population, the probability of overall survival, event-free survival (EFS) and disease-free survival (DFS) was 21·8% ± 6·2, 20·4% ± 5·9, and 49·5% ± 11·3, respectively. Twenty-eight (58%) patients received haematopoietic stem cell transplantation (HSCT); 3 were autologous and 25 were allogeneic. Patients who underwent HSCT had improved EFS (31·2% vs. 5%, P < 0·0001). Only one of the 20 patients who did not receive HSCT is alive and disease free. The 19 patients in complete remission at time of HSCT showed significantly better DFS than the 9 with active disease (46% vs. 0%, P = 0·02). This study represents one of the largest series with long-term follow up of paediatric AML patients with primary refractory disease. Children who underwent transplantation had an encouraging long-term outcome. Disease recurrence remains the major cause of treatment failure; a better understanding of the disease biology is desirable to develop more effective treatment strategies.

    One hundred ninety-eight children and adolescents were entered in the Associazione Italiana di Ematologia ed Oncologia Pediatrica (AIEOP)-ALL95 study for high-risk acute lymphoblastic leukemia (ALL). Inclusion criteria were poor response to initial prednisone/intrathecal methotrexate (prednisone-poor response [PPR]), resistance to induction therapy, translocation t(9;22), infants with the t(4;11), or CD10(-) ALL. The event-free survival (EFS) rate at 4 years was 56.5% (SE, 3.9%) for the entire group. The overall EFS rate in the current study was significantly better (P =.002) than that obtained in a comparable group of patients treated in the early 1990s in the AIEOP-ALL91 study. In particular, patients with PPR had a 4-year EFS of 61.1% (SE, 4.4%) versus 42.8% (SE, 5.4%) in the ALL 91 study (P =.008). Among PPR patients, those who were PPR-only (60.1%)-that is, they achieved CR and were negative for t(9;22) and t(4;11) translocations-had the best outcomes with this intensive treatment, even when additional adverse features (hyperleukocytosis, T phenotype) were present (4-year EFS, 70.1%; SE, 4.7%). We attribute this improvement to the replacement of 6 alternating blocks of non-cross-resistant drugs with an 8-drug reinduction regimen (Berlin-Frankfurt-Muenster [BFM] protocol II), repeated twice, in the context of a standard BFM-type intensive chemotherapy for high-risk ALL. This modified therapy may lead to high cure rates for patients defined as at high risk for intrinsic resistance to corticosteroids only.

    The first multicentric approach to childhood acute lymphoblastic leukemia (ALL) treatment in Italy started in the early 1970s when the Associazione Italiana di Ematologia ed Oncologia Pediatrica (AIEOP) was founded. Since then the AIEOP has conducted nationwide chemotherapy protocols. Results obtained in three different periods (1982-1986, 1987-1990, 1991-1995) are reported here. Treatment schedules have been characterized by a progressive intensification of systemic therapy and by a progressive substitution of protracted intrathecal therapy for cranial irradiation as central nervous system (CNS) preventive therapy. In the third period cranial radiotherapy (CRT) has been administered only to patients at high risk of relapse or with CNS involvement at diagnosis (about 15% of the overall population). A progressive improvement of therapeutic results, with a steady reduction of isolated CNS relapse rates have been obtained in the three periods considered here. The AIEOP experience shows that CRT can be safely omitted in non-high risk patients, unless they are T-ALL patients with WBC count at the diagnosis > or =100,000/mm3, and that intensification of treatment allows the improvement of overall results with a reduction of the impact of NCI prognostic criteria. Over the years, AIEOP has also continued to foster active cooperation at an international level. In the ongoing AIEOP ALL 2000 study, conducted in cooperation with the BFM group, patients are stratified according to the presence of translocations t(9;22) and t(4;11) and to treatment response (either initial steroid therapy or induction) or minimal residual disease). This cooperation will allow an adequate recruitment of patients to answer relevant randomized questions in the context of a study in which patients are stratified according to minimal residual disease findings.

    The Campi Flegrei caldera is one of the highest-risk volcanic areas on the Earth and the drilling exploiting activities carried by the Azienda Geologica Italiana Petroli (AGIP) and the Società Anonima Forze Endogene Napoletane (SAFEN) since the '40 have produced the main constrains to the definition of the subsurface structure of the caldera. The eastern part of the caldera represents among the least known in the area in terms of both volcanic and geothermal evolution. Recently, in the 2012, the Campi Flegrei Deep Drilling Project (CFDDP) allowed performing a 506m hole in this sector of the caldera, i.e. in the Bagnoli Plain, where the western districts of the Neapolitan city developed. Here, we present the preliminary results from mineralogical, geochemical and petrological investigations of drilling core samples collected at -443 m and -506 m of depths. Scanning electron microscopy (SEM), microanalysis by energy dispersive spectroscopy (EDS) together with investigations by back-scattered electron mode (SEM-BSE), and powder X-Ray diffraction (XRD) allowed: 1) defining the primary sample lithology; 2) examining the features of both primary and secondary minerals; 3) describing the relationships among texture and secondary mineralization. Sr isotope analyses were furthermore performed on separated feldspars. Density measurements were also carried out on the bottom core. The investigated samples are representative of strongly altered, massive pyroclastic tuffs, which made of a chaotic ashy to sandy matrix including low crystalline juvenile scoria and pumice fragments. Textural features of secondary mineralization are consistent with circulation of hydrothermal fluids as the results of a wide geothermal resource in the caldera. Comparing the paleo-temperature inferred by authigenic minerals occurrence and the temperature measured at the bottom hole (~60°C) during geophysical logs, we suggest the cooling of the hydrothermal system in the eastern sector of the caldera.

    ASTRI ("Astrofisica con Specchi a Tecnologia Replicante Italiana") is a flagship project of the Italian Ministry of Education, University and Research. Within this framework, INAF is currently developing a wide-field-of-view (9.6 degrees in diameter) end-to-end prototype of the small-size telescope (SST) of the Cherenkov Telescope Array, CTA, sensitive in the energy band from a few TeV up to hundreds TeV. The ASTRI telescope is based on a dual-mirror Schwarzschild-Couder (ASTRI SST-2M) optical design, with a compact (F# = 0.5) optical configuration named ASTRI SST-2M telescope. This allows us to adopt an innovative modular focal plane camera based on silicon photo-multipliers, with a logical pixel size of 6.2mm x 6.2mm. Moreover, planned, and already being developed, an SST mini-array based on 7 identical telescopes represents an evolution of the ASTRI SST-2M telescope. The ASTRI/CTA mini-array will be part of the CTA array, representing a precursor that will be included into the final array. With the mini-array, in addition to a technical assessment studies in the perpective of the full CTA implementation, it will be possible to perform an early scientific program. In particular we wish to start investigating the poorly known energy range between a few and 100 TeV, thus exploring e.g. the cut-off regime of cosmic accelerators. Apart from INAF, other international institutes will directly participate in the mini-array implementation, as the North-West University in South Africa and the University of Sao Paulo in Brazil. An interest about it has been expressed also by other international groups. In this talk we will report on the development status of the ASTRI prototype and ASTRI/CTA mini-array.

    The primary aim of this study was to evaluate the prevalence of opioid prescriptions in hospitalized geriatric patients. Other aims were to evaluate factors associated with opioid prescription, and whether or not there was consistency between the presence of pain and prescription. Opioid prescriptions were gathered from the REgistro POliterapie Societa` Italiana di Medicina Interna (REPOSI) data for the years 2008, 2010 and 2012. 1,380 in-patients, 65+ years old, were enrolled in the first registry run, 1,332 in the second and 1,340 in the third. The prevalence of opioid prescription was calculated at hospital admission and discharge. In the third run of the registry, the degree of pain was assessed by means of a numerical scale. The prevalence of patients prescribed with opioids at admission was 3.8% in the first run, 3.6% in the second and 4.1% in the third, whereas at discharge rates were slightly higher (5.8, 5.3, and 6.6%). The most frequently prescribed agents were mild opioids such as codeine and tramadol. The number of total prescribed drugs was positively associated with opioid prescription in the three runs; in the third, dementia and a better functional status were inversely associated with opioid prescription. Finally, as many as 58% of patients with significant pain at discharge were prescribed no analgesic at all. The conservative attitude of Italian physicians to prescribe opioids in elderly patients changed very little between hospital admission and discharge through a period of 5 years. Reasons for such a low opioid prescription should be sought in physicians' and patients' concerns and prejudices.

    The characteristics of background seismic noise in north central Italy have been investigated by means of velocity power spectral analysis within the frequency range 0.1-15 Hz. The method proposed by McNamara and Buland (2004) has been applied to estimate the probability density function (PDF) of power spectra computed for ten different stations. Since the target region is the most industrialized area of Italy, a large variability among the power spectra for different sites is observed in the frequency range 1-15 Hz, with the noise levels at two stations exceeding the New High Noise Model (NHNM) of Peterson (1993). The 95th percentile of the PDF varies from -165 to -125 dB (relative to (m/s)2/Hz). This variability could significantly affect the detection capabilities of a network installed for recording the small to moderate size seismicity occurring in north central Italy. We also observed that the dispersion of the powers, estimated at each site as the difference between the 95th and the 5th percentiles, shows a positive trend with frequency that can be ascribed to the diurnal variation of the background noise levels. In the frequency range 0.1-1 Hz, the dominant feature is the double frequency (DF) peak of microseisms generated by oceanic storms. At one of the considered stations, the seasonal variability of the maximum amplitude of the DF peak has been observed in the period from April 2004 to December 2005. Considering the barometric maps provided by the UK Meteorological Office, we observed that the strongest powers in the range 0.10-0.25 Hz occur when intense storms are present over the North Atlantic Ocean, whereas the measurements of the height, frequency, and azimuth of the sea waves at two buoys of the Rete Ondametrica Italiana deployed in the Adriatic and Tyrrhenian seas suggest that the DF microseisms in the frequency range 0.25-0.50 Hz are generated by storms over the Mediterranean Sea. Finally, the analyzed region is characterized by two large

    The RISPArMiA project (which stands for "reduction of water wastage through the continuous monitoring of agri-environmental parameters") won in 2013 the contest called "LINFAS - The New Ideas Make Sustainable Agriculture" and sponsored by two Italian Foundations (Fondazione Italiana Accenture and Fondazione Collegio Università Milanesi). The objective of the RISPArMiA project is to improve the irrigation efficiency at the farm scale, by providing the farmer with a valuable decision support system for the management of irrigation through the use of low-cost sensors and technologies that can easily be interfaced with Mobile devices. Through the installation of tensiometric sensors within the cropped field, the soil water potential can be continuously monitored. Using open hardware electronic platforms, a data-logger for storing the measured data will be built. Data will be then processed through a software that will allow the conversion of the monitored information into an irrigation advice. This will be notified to the farmer if the measured soil water potential exceed literature crop-specific tensiometric thresholds. Through an extrapolation conducted on the most recent monitored data, it will be also possible to obtain a simple soil water potential prevision in absence of rain events. All the information will be sent directly to a virtual server and successively on the farmer Mobile devices. Each micro-station is completely autonomous from the energy point of view, since it is powered by batteries recharged by a solar panel. The transmission modulus consists of a GSM apparatus with a SIM card. The use of free platforms (Arduino) and low cost sensors (Watermark 200SS tensiometers and soil thermocouples) will significantly reduce the costs of construction of the micro-station which are expected to be considerably lower than those required for similar instruments on the market today . Six prototype micro-stations are actually under construction. Their field testing

    Reports of unrelated individuals with autism spectrum disorder (ASD) and similar clinical features having overlapping de novo interstitial deletions at 2p15-p16.1 suggest that this region harbors a gene(s) important to the development of autism. We molecularly characterized two such deletions, selecting two genes in this region, exportin 1 (XPO1) and orthodenticle homolog 1 (OTX1) for association studies in three North American cohorts (Autism Spectrum Disorder - Canadian American Research Consortium (ASD-CARC), New York, and Autism Genetic Resource Exchange (AGRE)) and one Italian cohort (Società Italiana per la Ricerca e la Formazione sull'Autismo (SIRFA)) of families with ASD. In XPO1, rs6735330 was associated with autism in all four cohorts (P<0.05), being significant in ASD-CARC cohorts (P-value following false discovery rate correction for multiple testing (P(FDR))=1.29 × 10(-5)), the AGRE cohort (P(FDR)=0.0011) and the combined families (P(FDR)=2.34 × 10(-9)). Similarly, in OTX1, rs2018650 and rs13000344 were associated with autism in ASD-CARC cohorts (P(FDR)=8.65 × 10(-7) and 6.07 × 10(5), respectively), AGRE cohort (P(FDR)=0.0034 and 0.015, respectively) and the combined families (P(FDR)=2.34 × 10(-9) and 0.00017, respectively); associations were marginal or insignificant in the New York and SIRFA cohorts. A significant association (P(FDR)=2.63 × 10(-11)) was found for the rs2018650G-rs13000344C haplotype. The above three SNPs were associated with severity of social interaction and verbal communication deficits and repetitive behaviors (P-values <0.01). No additional deletions were identified following screening of 798 ASD individuals. Our results indicate that deletion 2p15-p16.1 is not commonly associated with idiopathic ASD, but represents a novel contiguous gene syndrome associated with a constellation of phenotypic features (autism, intellectual disability, craniofacial/CNS dysmorphology), and that XPO1 and OXT1 may contribute to ASD in 2p15-p

    Purpose: To evaluate the recombination effect for some ionization chambers to be used for linacs commissioning for Flattened Filter (FF) and Flattening Filter Free (FFF) photon beams. Methods: A Varian TrueBeam linac with five photon beams was used: 6, 10 and 15 MV FF and 6 and 10 MV FFF. Measurements were performed in a water tank and in a plastic water phantom with different chambers: a mini-ion chamber (IC CC01, IBA), a plane-parallel ion chamber (IC PPC05, IBA) and two Farmer chambers (NE2581 and FPC05-IBA). Measurement conditions were Source- Surface Distance of 100 cm, two field sizes (10x10 and 40x40 cm2) and five depths (1cm, maximum buildup, 5cm, 10cm and 20cm). The ion recombination factors (kS), obtained from the Jaffe's plots (voltage interval 50-400 V), were evaluated at the recommended operating voltage of +300V. Results: Dose Per Pulse (DPP) at dmax was 0.4 mGy/pulse for FF beams, 1.0 mGy/pulse and 1.9 mGy/pulse for 6MV and 10 MV FFF beams respectively. For all measurement conditions, kS ranged between 0.996 and 0.999 for IC PPC05, 0.997 and 1.008 for IC CC01. For the FPC05 IBA Farmer IC, kS varied from 1.001 to 1.011 for FF beams, from 1.004 to 1.015 for 6 MV FFF and from 1.009 to 1.025 for 10 MV FFF. Whereas, for NE2581 IC the values ranged from 1.002 to 1.009 for all energy beams and measurement conditions. Conclusion: kS depends on the chamber volume and the DPP, which in turn depends on energy beam but is independent of dose rate. Ion chambers with small active volume can be reliably used for dosimetry of FF and FFF beams even without kS correction. On the contrary, for absolute dosimetry of FFF beams by Farmer ICs it is necessary to evaluate and apply the kS correction. Partially supported by Lega Italiana Lotta contro i Tumori (LILT)

    In Italy, according to the International Study on Asthma and Allergies in Childhood study, the prevalence of current asthma, allergic rhinoconjunctivitis, and atopic eczema in 2006 was 7.9%, 6.5%, and 10.1% among children aged 6-7 and 8.4%, 15.5%, and 7.75% among children aged 13-14 yr. University education in this field is provided by the Postgraduate Schools of Pediatrics and those of Allergology and Clinical Immunology, as well as several annual Master courses. The Italian Society of Pediatric Allergology and Immunology (SIAIP) was founded in 1996 and counts about 1000 members. SIAIP promotes evidence-based management of allergic children and disseminates information to patients and their families through a quite innovative website and the National Journal 'Rivista Italiana di Allergologia Pediatrica'. In the last decade, four major regional, inter-regional, and national web-based networks have been created to link pediatric allergy centers and to share their clinical protocols and epidemiologic data. In addition, National Registers of Primary Immune-deficiencies and on Pediatric HIV link all clinical excellence centers. Research projects in the field of pediatric allergy and immunology are founded by the Italian Ministry of Education, University and Research (MIUR) and by the National Research Council (CNR), but the overall investments in this research area are quite low. Only a handful Italian excellence centers participate in European Projects on Pediatric Allergy and Immunology within the 7th Framework Program. The European Academy of Allergy and Clinical Immunology currently hosts two Italians in its Executive Committee (EC) and one in the EC of the Pediatric Section; moreover, major European Academy of Allergy and Clinical Immunology meetings and courses in the area of pediatrics (e.g., PAAM, Venice, 2009) have been held in Italy in the last 3 yr.

    The annual Conference of the ''Unione Italiana di Termofluidodinamica'' (UIT) aims to promote cooperation in the field of heat transfer and thermal sciences by bringing together scientists and engineers working in related areas. The 32nd UIT Conference was held in Pisa, from the 23rd to the 25th of June, 2014 in the buildings of the School of Engineering, just a few months after the celebration of the 100th anniversary of the first Institution of the School of Engineering at the University of Pisa. The response was very good, with more than 100 participants and 80 high-quality contributions from 208 authors on seven different heat transfer related topics: Heat transfer and efficiency in energy systems, environmental technologies, and buildings (25 papers); Micro and nano scale thermo-fluid dynamics (9 papers); Multi-phase fluid dynamics, heat transfer and interface phenomena (14 papers); Computational fluid dynamics and heat transfer (10 papers); Heat transfer in nuclear plants (8 papers); Natural, forced and mixed convection (10 papers) and Conduction and radiation (4 papers). To encourage the debate, the Conference Program scheduled 16 oral sessions (44 papers), three ample poster sessions (36 papers) and four invited lectures given by experts in the various fields both from Industry and from University. Keynote Lectures were given by Dr. Roberto Parri (ENEL, Italy), Prof. Peter Stephan (TU Darmstadt, Germany), Prof. Bruno Panella (Politecnico di Torino), and Prof. Sara Rainieri (Universit;aacute; di Parma). This special volume collects a selection of the scientific contributions discussed during this conference. A total of 46 contributions, two keynote lectures and 44 papers both from oral and poster sessions, have been selected for publication in this special issue, after a second accurate revision process. These works give a good overview of the state of the art of Italian research in the field of Heat Transfer related topics at the date. The editors of the

    Genetic abnormalities and early treatment response are the main prognostic factors in acute myeloid leukemia (AML). Acute megakaryoblastic leukemia (AMKL) is a rare subtype of AML. Deep sequencing has identified CBFA2T3/GLIS2 and NUP98/KDM5A as recurrent aberrations, occurring in similar frequencies as RBM15/MKL1 and KMT2A-rearrangements. We studied whether these cytogenetic aberrations can be used for risk group stratification. To assess frequencies and outcome parameters of recurrent cytogenetic aberrations in AMKL, samples and clinical data of patients treated by the Associazione Italiana Ematologia Oncologia Pediatrica, Berlin-Frankfurt-Munster Study Group, Children's Oncology Group, Dutch Childhood Oncology Group, and the Saint Louis Hôpital were collected, enabling us to screen 153 newly diagnosed pediatric AMKL cases for the aforementioned aberrations and to study their clinical characteristics and outcome. CBFA2T3/GLIS2 was identified in 16% of the cases; RBM15/MKL1, in 12%; NUP98/KDM5A and KMT2A rearrangements, in 9% each; and monosomy 7, in 6%. These aberrations were mutually exclusive. RBM15/MKL1-rearranged patients were significantly younger. No significant differences in sex and white blood cell count were found. NUP98/KDM5A, CBFA2T3/GLIS2, KMT2A-rearranged lesions and monosomy 7 (NCK-7) independently predicted a poor outcome, compared with RBM15/MKL1-rearranged patients and those with AMKL not carrying these molecular lesions. NCK-7-patients (n = 61) showed a 4-year probability of overall survival of 35 ± 6% vs 70 ± 5% in the RBM15/MKL1-other groups (n = 92, P < .0001) and 4-year probability of event-free survival of 33 ± 6% vs 62 ± 5% (P = .0013), the 4-year cumulative incidence of relapse being 42 ± 7% and 19 ± 4% (P = .003), respectively. We conclude that these genetic aberrations may be used for risk group stratification of pediatric AMKL and for treatment tailoring.

    Twenty-seven consecutive Italian patients with Fanconi's anaemia (FA) underwent stem cell transplantation (SCT) from an HLA-matched related donor in 10 Italian centres of the Associazione Italiana Ematologia ed Oncologia Pediatrica (AIEOP), Gruppo Italiano di Trapianto di Midollo Osseo (GITMO). Twenty-two patients (81.5%) were conditioned with low-dose (median 20 mg/kg) cyclophosphamide (Cy) and thoraco-abdominal or total body irradiation (median dose 500 cGy), five patients (18.5%) with high-dose Cy (median 120 mg/kg). Graft-vs.-host disease (GVHD) prophylaxis was carried out with cyclosporin A in 26 cases; methotrexate (MTX) was added in eight cases. One patient received MTX alone. The median follow-up was 36 months. Ninety-two percent of patients (25 out of 27) engrafted, grade II and III acute GVHD occurred in 28% and 8% of patients, respectively, with chronic GVHD in 12.5%. Conditioning-related toxicity was mild: 4% of patients had grade III mucositis, 7.4% had grade II haemorrhagic cystitis, 14.8% had grade III liver toxicity and 11.1% had grade III renal toxicity. Transplant-related mortality at 12 months was 19.2%, survival at 36 months was 81.5%, with a median Karnofsky score of 100%. No late tumours occurred after a mean follow-up of the survivors of 5 years. None of the studied variables significantly affected the survival, including conditioning regimen, acute GVHD and clinical non-haematological phenotype. Among the studied variables, only conditioning regimens containing high-dose Cy and the presence of genital abnormalities were significantly (P < 0.05) associated with an increased rate of acute GVHD. Our study demonstrates that the Italian FA patients undergoing SCT from an HLA-matched related donor have a very good outcome. These patients, when compared with others of different ethnic origin who underwent allogeneic bone marrow transplantation, showed a less severe non-haematological phenotype, raising the possibility that this milder phenotype may

    Induction therapy for childhood acute lymphoblastic leukemia (ALL) traditionally includes prednisone; yet, dexamethasone may have higher antileukemic potency, leading to fewer relapses and improved survival. After a 7-day prednisone prephase, 3720 patients enrolled on trial Associazione Italiana di Ematologia e Oncologia Pediatrica and Berlin-Frankfurt-Münster (AIEOP-BFM) ALL 2000 were randomly selected to receive either dexamethasone (10 mg/m(2) per day) or prednisone (60 mg/m(2) per day) for 3 weeks plus tapering in induction. The 5-year cumulative incidence of relapse (± standard error) was 10.8 ± 0.7% in the dexamethasone and 15.6 ± 0.8% in the prednisone group (P < .0001), showing the largest effect on extramedullary relapses. The benefit of dexamethasone was partially counterbalanced by a significantly higher induction-related death rate (2.5% vs 0.9%, P = .00013), resulting in 5-year event-free survival rates of 83.9 ± 0.9% for dexamethasone and 80.8 ± 0.9% for prednisone (P = .024). No difference was seen in 5-year overall survival (OS) in the total cohort (dexamethasone, 90.3 ± 0.7%; prednisone, 90.5 ± 0.7%). Retrospective analyses of predefined subgroups revealed a significant survival benefit from dexamethasone only for patients with T-cell ALL and good response to the prednisone prephase (prednisone good-response [PGR]) (dexamethasone, 91.4 ± 2.4%; prednisone, 82.6 ± 3.2%; P = .036). In patients with precursor B-cell ALL and PGR, survival after relapse was found to be significantly worse if patients were previously assigned to the dexamethasone arm. We conclude that, for patients with PGR in the large subgroup of precursor B-cell ALL, dexamethasone especially reduced the incidence of better salvageable relapses, resulting in inferior survival after relapse. This explains the lack of benefit from dexamethasone in overall survival that we observed in the total cohort except in the subset of T-cell ALL patients with PGR. This trial was registered

    Asparaginases are important agents used in the treatment of children with acute lymphoblastic leukemia (ALL). Three types of asparaginase are currently available: two are derived from Escherichia coli [native asparaginase and pegylated asparaginase (PEG-asparaginase)] and one from Erwinia chrysanthemi (crisantaspase). All three products share the same mechanism of action but have different pharmacokinetic properties, which do not make them easily interchangeable. Among the known toxicities and side-effects, allergic reactions and silent inactivation represent the most important limitations to the prolonged use of any asparaginase product, with associated reduced therapeutic effects and poorer outcomes. Routine real time monitoring can help to identify patients with silent inactivation and facilitate a switch to a different product to ensure continued depletion of asparagine, completion of the treatment schedule and maintenance of outcomes. However, the most appropriate second-line treatment is still a matter of debate. PEG-asparaginase has lower immunogenicity and a longer half-life than native Escherichia coli (E. coli) asparaginase, which makes it useful for both first-line and second-line use with a reduced number of doses. However, PEG-asparaginase displays cross-reactivity with native E. coli asparaginase that may harm its therapeutic effects. Crisantaspase does not display cross-reactivity to either of the E. coli-derived products, which has made crisantaspase the second-line treatment option in a number of recent protocols. As crisantaspase has a much shorter biological half-life than the E. coli-derived products, the appropriate dosage and administration schedule are of paramount importance in delivering treatment with this product. In the ongoing trial AIEOP-BFM ALL 2009 (Associazione Italiana Ematologia Oncologia Pediatrica - Berlin-Franklin-Munster), in which PEG-asparaginase is used first-line, one dose of PEG-asparaginase is substituted by seven doses

    A multicenter observational study, REPOSI (REgistro POliterapie Società Italiana di Medicina Interna), was conducted to assess the prognostic value of glomerular filtration rate (eGFR) on in-hospital mortality, hospital re-admission and death within 3 months, in a sample of elderly patients (n = 1,363) admitted to 66 internal medicine and geriatric wards. Based on eGFR, calculated by the new Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, subjects at hospital admission were classified into three groups: group 1 with normal eGFR (≥60 ml/min/1.73 m(2), reference group), group 2 with moderately reduced eGFR (30-59 ml/min/1.73 m(2)) and group 3 with severely reduced eGFR (<30 ml/min/1.73 m(2)). Patients with the lowest eGFR (group 3) on admission were more likely to be older, to have a greater cognitive and functional impairment and a high rate of comorbidities. Multivariable logistic regression analysis showed that severely reduced eGFR at the time of admission was associated with in-hospital mortality (OR 3.00; 95% CI 1.20-7.39, p = 0.0230), but not with re-hospitalization (OR 0.97; 95% CI 0.54-1.76, p = 0.9156) or mortality at 3 months after discharge (OR 1.93; 95% CI 0.92-4.04, p = 0.1582). On the contrary, an increased risk (OR 2.60; 95% CI 1.13-5.98, p = 0.0813) to die within 3 months after discharge was associated with decreased eGFR measured at the time of discharge. Our study demonstrates that severely reduced eGFRs in elderly patients admitted to hospital are strong predictors of the risk of dying during hospitalization, and that this measurement at the time of discharge helps to predict early death after hospitalization.

Although soil temperature and soil moisture exert a strong influence over the variation in SR, our results indicates that substrate supply by plant activity could exert a more important than previously expected role in the variability of soil respiration. 1.

  20. ESA is hot on the trail of Geminga

    NASA Astrophysics Data System (ADS)

    XMM-Newton image of Geminga showing the discovery of the twi hi-res Size hi-res: 68 kb Credits: ESA XMM-Newton image of Geminga showing the discovery of the twin tails This image was captured by the EPIC camera on board the satellite. The motion of Geminga across the sky is indicated, showing that the tails are trailing the neutron star. The scale bar corresponds to a distance of 1.5 million million kilometres at the distance of Geminga. Computer models of the shock wave created by Geminga hi-res Size hi-res: 522 kb Credits: Patrizia Caraveo Computer models of the shockwave created by Geminga Computer models of the shockwave created by Geminga show that the best matches to the data occur if the neutron star is travelling virtually across our line of sight. These correspond to the inclinations of less than 30 degrees. A neutron star measures only 20-30 kilometres across and is the dense remnant of an exploded star. Geminga is one of the closest to Earth, at a distance of about 500 light-years. Most neutron stars emit radio emissions, appearing to pulsate like a lighthouse, but Geminga is 'radio-quiet'. It does, however, emit huge quantities of pulsating gamma rays making it one of the brightest gamma-ray sources in the sky. Geminga is the only example of a successfully identified gamma-ray source from which astronomers have gained significant knowledge. It is 350 000 years old and ploughs through space at 120 kilometres per second. Its route creates a shockwave that compresses the gas of the interstellar medium and its naturally embedded magnetic field by a factor of four. Patrizia Caraveo, Instituto di Astrofisica Spaziale e Fisica Cosmica, Milano, Italy, and her colleagues (at CESR, France, ESO and MPE, Germany) have calculated that the tails are produced because highly energetic electrons become trapped in this enhanced magnetic field. As the electrons spiral inside the magnetic field, they emit the X-rays seen by XMM-Newton. The electrons themselves are created

    2006-10-01

    Nel corso dell’ultimo decennio l’esplorazione planetaria ha potuto beneficiare dei dati prodotti dagli spettrometri ad immagine: grazie a questa nuova classe di strumenti, realizzati per l’osservazione in remoto di superfici ed atmosfere planetarie, è possibile acquisire dati iperspettrali con elevati poteri risolutivi spaziali e spettrali. Il principale vantaggio offerto dagli spettrometri ad immagine, rispetto alle camere ed agli spettrometri puntuali, è rappresentato dalla capacità di misurare, identificare e mappare le unità composizionali delle superfici planetarie; queste informazioni permettono di investigare sia l’evoluzione geochimica delle superfici sia la dinamica e la composizione delle atmosfere. Sebbene i primi spettrometri ad immagine siano stati francesi (Phobos/ISM, Imaging Spectrometer for Mars) e statunitensi (Galileo/NIMS, Near Infrared Mapping Spectrometer), il nostro paese nel corso degli ultimi anni è stato in grado di proporre alla com unità spaziale internazionale degli strumenti dalle elevate prestazioni che sono stati infatti accettati come payload scientifici su diverse missioni interplanetarie: dai canali visibili di VIMS (Visual and Infrared Mapping Spectrometer) su Cassini (Nasa, JPL, ESA, ASI) e di OMEGA (Observatoire pour la Minéralogie, l’Eau, les Glacies et l’Activitè de Mars) su MarsExpress (ESA) ai due VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) su Rosetta (ESA) e VenusExpress (ESA) fino a VIR-MS (Visible and Infrared Mapping Spectrometer) su Dawn (Nasa). In questo momento inoltre altri due spettrometri sono in avanzata fase di studio: JIRAM (Jovian InfraRed Auroral Mapper) su Juno (missione New Discovery Nasa) e VIHI (Visible and Infrared Hyperspectral Imager) integrato nel payload italiano di remote sensing SIMBIO-SYS di BepiColombo (missione cornerstone ESA).

    -rock major and trace element contents by LA-ICP-MS (Elan DRCe, Perkin Elmer/SCIEX, connected to a New Wave UP213 solid-state Nd-YAG laser probe); particularly, being this method almost non-destructive, it is very useful for "in situ" determination of minor to trace elements of selected areas of archaeological artefacts with a high degree of accuracy and precision and very low detection limits. The investigated artefacts mainly belong to a type of fired mixture, called concotto by Italian archaeologists (Bertelle et al., 2001). They are mostly red-orange, but also grey and whitish in colour; their textures are heterogeneous, with numerous inclusions of waste pottery, lithics (leucitic lava) and loose crystals (leucite, clinopyroxene, feldspar, mica, quartz) into a matrix mainly made of iron-rich amorphous material, with variable amounts of hematite, magnetite, kaolinite and smectite. Locally, vivianite (hydrate iron phosphate), calcite and gypsum were detected. The concotti resulted in sturdy materials, particularly suitable for humid environments. Suggestions on possible temperature production are also given. References Balassone G., Boni M., Di Maio G., Igor M. Villa I.M.

    the wheel profile, obtaining the correspondent worn wheel geometry. The wheel wear evolution is reproduced by dividing the overall chosen mileage to be simulated in discrete spatial steps: at each step, the dynamic simulations are performed by means of the 3D multibody model keeping the wheel profile constant, while the wheel geometry is updated through the wear model only at the end of the discrete step. Thus, the two parts of the whole model work alternately until the completion of the whole established mileage. Clearly, the choice of an appropriate step length is one of the most important aspects of the procedure and it directly affects the result accuracy and the required computational time to complete the analysis. The whole model has been validated using experimental data relative to tests performed with the ALn 501 'Minuetto' vehicle in service on the Aosta-Pre Saint Didier track; this work has been carried out thanks to a collaboration with Trenitalia S.p.A and Rete Ferroviaria Italiana, which have provided the necessary technical data and experimental results.

Particular care was given to organic clays within the lacustrine deposits, which show a stronger linearity and lower damping ratio with respect to inorganic clays of similar plasticity. The collected geological-geophysical dataset suggests the coalescence of several eruptive centres localized at different depths and laterally distributed within the present-day Stracciacappa maar.

This may be due to different causes: a) volatiles degassing from near-surface melts beneath Mt. Vulture are quantitatively dominant with respect to crustal gases, in contrast to gas emissions located close to the peri-Thyrrenian area and/or b) the 3He/4He of the peri-Tyrrhenian magmas is expected to be lower than 6 Ra.

    RIASSUNTO Introduzione I parametri di pressione arteriosa, sistolica (PAS) o diastolica (PAD) hanno costituito I’oggetto di numerosi studi, alcuni dei quali stabiliscono un’associazione tra I’aumnto di tali parametri e la mortalità, in particolare alle età medie. I fattori di rischio di ipertensione più frequentemente studiati sono il consumo di alcol, il fumo e I’origine etnica in riferimento sia alle differenze genetiche che nella condotta alimentare, mentre i fattori di origine professionale sono stati presi in considerazione più raramente e in maniera poco approfondita, inoltre sono state riferite notevoli differenze nelle pressioni arteriose medie di individui che svolgono professioni diverse. Sembra infatti che i “colletti blu” siano più a rischio dei “colletti bianchi”. Obiettivi Il nostro scopo è valutare se determinati rischi o vincoli connessi con l’attività professionale o determinati stili di vita rappresentano un fattore di rischio per l’ipertensione arteriosa in considerazioni dell’aumentare dell’età. Elementi specifici che rendano conto di questa relazione non sono stati ancora completamente chiariti e soprattutto i dati sulla popolazione italiana sono molto limitati. Metodi La metodologia di ricerca utilizzata è stata quella dell’indagine francese ESTEV (Derriennic, Touranchet, Volkoff) - VISAT (Marquie, Janson), studio epidemiologico longitudinale su oltre 23000 lavoratori attivata in Francia nel 1990 al fine di indagare gli effetti a lungo termine delle condizioni di lavoro, riferite all’intera vita professionale, sia sull’invecchiamento sia sulla salute dei lavoratori. Analoga indagine è stata avviata in Italia, nel 2000, in 6 Regioni, prendendo in esame i lavoratori dipendenti di diversi settori produttivi appartenenti a 5 coorti di età: da 32 a 52 anni con intervallo di 5 anni.

    retired in 2000. He attached great importance to the value of scientific publication and to the ethics involved in producing scientific literature. He had a very strong interest in the historical aspects of animal diseases and, in 2003, published a valuable book entitled History of the surveillance and control of transmissible animal diseases. He would always ensure that the most interesting and appropriate historic illustrations, irrespective of how difficult they were to obtain, were selected for the papers he published. Among some of the activities Jean Blancou undertook during his retirement was the mammoth task of co-editing Infectious and parasitic diseases of livestock in French and English. Dr Blancou authored over 370 scientific publications devoted to animal diseases, to the production and control of biologicals and, of course, many authoritative articles on rabies and vaccinology. He was always generous with the scientific knowledge he possessed and never missed an opportunity to assist colleagues in the preparation or correction of manuscripts that they wished to submit to peer-reviewed journals. He was gentle in nature and always softly spoken. As one of his colleagues wrote: 'we have lost a most gentle, thoughtful and kind man and the world has lost one of its stellar veterinarians'. Despite his busy and brilliant career, Jean Blancou was a family man and devoted to the education of his children. During his illness, he showed great courage. The Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise 'G. Caporale' has been privileged to benefit from the expert knowledge and experience that Dr Blancou so generously provided in his capacity as Member of the Scientific Advisory Board of Veterinaria Italiana. Jean Blancou is survived by his wife, Geneviève, his children and grandchildren.

    first case we will try at least to reproduce the observed signal, otherwise we will try to understand whether the non-tsunamigenic nature of the event is confirmed by the tsunami simulations. The second problem is more related to tsunami early warning issues, in particular with the performance of the Tsunami Decision Matrix for the Mediterranean, presently adopted for example by the candidate Tsunami Service Providers at NOA (Greece) and INGV (Italy). We will briefly discuss whether the present form of the matrix, which does not include any information on focal mechanism, is well suited to a peculiar event like the November 17 earthquake, which was of strike-slip nature and had a magnitude lying just at the border between two distinct classes of tsunami potential forecast. This study is funded in the frame of the EU Project called ASTARTE - "Assessment, STrategy And Risk Reduction for Tsunamis in Europe", Grant 603839, 7th FP (ENV.2013.6.4-3), and of the Italian Flagship Project RITMARE ("La Ricerca ITaliana per il MARE").

    As part of the actions of the flagship project RITMARE (Ricerca ITaliana per il MARE) a daily oceanographic survey was performed on 29th November 2013 in front of the Po River delta (Northern Adriatic Sea). The Po river affects a large part of the Northern Adriatic Sea with strong implications on the circulation and functionality of the basin. Physical-chemical and biological properties of coastal waters were investigated after a moderate flood occurred around 25th-27th November. The cruise activities, carried out using a small research boat, were mainly focused on the test of a methodological approach to investigate the environment variability after a flood event in the framework of rapid assessment. The effects of the flood on the coastal waters, have been evaluated in the field using operational forecasts and real-time satellite imagery to assist field measurements and samplings. Surface satellite chlorophyll maps and surface salinity and current maps obtained from a numerical model forced by meteorological forecast and river data were analyzed to better identify the Po plume dispersion during and after the event in order to better locate offshore monitoring stations at the sea. Profiles of Temperature, Salinity, Turbidity, Fluorescence and Colored Dissolved Organic Matter (CDOM) throughout the water column were collected at 7 stations in front of the Po River delta. Sea surface water samples were also collected for the analysis of nutrients, Dissolved Organic Carbon (DOC) and CDOM (surface and bottom). The CDOM regulates the penetration of UV light throughout the water column and mediates photochemical reactions, playing an important role in many marine biogeochemical processes. Satellite images showed a strong color front that separates the higher-chlorophyll coastal water from the more oligotrophic mid-basin and eastern boundary Adriatic waters. In front of the river mouth, the surface layer was characterized by low salinity (14-15), high turbidity (8-11 NTU

The aim of FFRM is to provide an estimation of the damage risk caused by flash-floods for the whole of Upper Austria. To address the hazard, inundation depths were calculated with the extended 2D-model using design rains with an 100-year return period provided by the Environmental Ministry [7]. The potential damage was calculated using damage functions, which were derived from our experience from damage surveys of past events in Austria and according to guidelines for determination of cost-benefit-ratios for flood protection measures [8]. The greatest difficulty was to get appropriate data for the distribution of houses and industrial plants. Zoning plans provide good information on spatial distribution of residential, commercial and industrial areas, but does not contain information on the kind of industry, which is essential for estimating absolute damage values. To get a first idea detailed information from surveyed areas was intersected with the zoning plan, which provides an average damage in the respective zones. The first results can be found on www.waterviewer.com and will be updated with the further development of the project.

    at successive testing performed 2 months later. As of September 30, 1995, after a median follow-up period from diagnosis of 27 months (range, 24 to 31 months), the overall survival and event-free survival durations are 85% and 69%, respectively; moreover, 14 of 18 (78%) patients who achieved CR are still alive and in first molecular and hematologic CR. Of the 4 relapsed patients, 3 achieved a second CR with ATRA and, after further treatment, are now in molecular and hematologic CR after 4+, 16+, and 17+ months from the second CR. These results indicate that (1) the AIDA protocol is highly effective in treating APL; (2) after 3 consolidation courses, the majority of patients who achieved CR are RT-PCR- for the hybrid gene PML-RAR alpha; (3) the persistence of an RT-PCR positivity for the PML-RAR alpha hybrid gene after 3 consolidation courses is indicative of early relapse, thus these patients still require additional treatment. These results have prompted the Gruppo Italiano Malattie Ematologiche Maligne dell'Adulto (GIMEMA) to initiate, in cooperation with the Associazione Italiana di Ematologia ed Oncologia Pediatrica and some European Organization for Research and Treatment of Cancer (EORTC) centers, a new multicentric clinical trial named AIDA LAP 0493 for the treatment of adult and pediatric APL patients. All patients are considered eligible if APL diagnosis is confirmed with molecular or cytogenetic studies for PML-RAR alpha hybrid gene or t(15;17) and are enrolled to receive the same induction and consolidation therapy of this pilot study. After consolidation, patients who are RT-PCR- for PML-RAR alpha hybrid gene are randomized to four arms, whereas patients who are RT-PCR+ after consolidation undergo, if eligible, an allogenic transplantation procedure.

    menace potentielle pour la ville de Venise, à 25 km au nord-ouest du centre de Chioggia Mare. Afin d'évaluer le risque de subsidence du sol provoquée par les prélèvements de gaz, un modèle numérique a été développé pour prévoir la compaction des formations réservoirs de gaz en même temps que celle de l'aquifère latéral et sous-jacent, par effet de drainance, sur une période de 13 ans de production, suivie de 12 ans, et pour prévoir le transfert de la compaction profonde jusqu'à la surface du sol. Afin de prendre en compte l'incertitude sur un petit nombre de paramètres hydromécaniques importants, plusieurs scénarios ont été simulés et les prévisions les plus pessimistes ont été obtenues. Les résultats de la modélisation montrent qu'on doit s'attendre, au cours des 25 ans, au plus à une subsidence du sol de 1 cm à Chioggia, tandis que Venise ne subira aucun effet. Si la baisse de l'aquifère est compensée par une injection d'eau, la subsidence du sol s'arrêtera à 5 km au large et la zone côtière de Chioggia subira un effet de 0,6 à 0,7 cm. Resumen. Recientemente, la compañía nacional italiana del petróleo, ENI-Agip, ha enviado al Ministerio de Medio Ambiente de Italia (Comité VIA) un gran programa de desarrollo de 15 campos de gas en el norte del Mar Adriático para la evaluación de su impacto medioambiental. Una de las reservas principales de gas se halla en el mar de Chioggia, a unos 10 km mar adentro de la costa veneciana, a una profundidad de entre 1.000 y 1.400 m. Se espera que la producción en este campo produzca un impacto en la estabilidad de la línea de costa, y que suponga una amenaza potencial para la ciudad de Venecia, situada a 25 km al noroeste de la explotación. Se desarrolló un modelo numérico para evaluar el riesgo de subsidencia debido a la extracción de gas a lo largo de los 13 años de producción y del período post-productivo de 12 años. Sus predicciones indican que se causará la compactación tanto

    ère et l'adolescent partageaient des perceptions similaires, tandis qu'une différence significative a émergé entre la mère et l'enfant. Un plus grand niveau de congruence perceptuelle entre les adolescents et les parents a été trouvé dans les familles d'accueil. Des différences entre les sexes ont aussi apparu: en comparaison aux pères, les mères ont expérimenté une communication plus ouverte avec leurs enfants et les adolescents, surtout les filles, communiquaient mieux avec leurs mères qu'avec leurs pères dans les trois groupes familiaux. Son escasos los estudios que se han propuesto comparar cómo los padres e hijos pertenecientes a diferentes estructuras familiares afrontan los retos que impone la transición a la adolescencia; en particular, pocos estudios comparan las familias adoptivas y las que ejercen el cuidado temporal. Para subsanar parcialmente esta deficiencia, los propósitos principales de el presente estudio fueron verificar si difiere la comunicación padres-hijos entre familias que ejercen cuidado temporal, aquéllas adoptivas entre países, y biológicas de acuerdo con el sexo del adolescente, y comparar las percepciones de los padres y de los adolescentes en cuanto a la comunicación padres-hijo. Los datos se analizaron en dos niveles: un nivel de generaciones (las percepciones del adolescente y de sus padres entre los tres grupos de familias) y un nivel de díadas (las percepciones madre-hijo y padre-hijo). Doscientas setenta y seis familias italianas con adolescentes entre 11 y 17 años de edad (81 familias de cuidado temporal, 98 adoptivas internacionalmente y 97 biológicas) constituyeron la muestra. Los participantes (madres, padres e hijos) respondieron a un cuestionario que incluía la Escala de Comunicación Padre-Adolescente (Barnes & Olson, 1985 ). Los resultados resaltan más dificultades en la comunicación padres-hijo en las familias que ejercen cuidado temporal, tanto desde la perspectiva del adolescente como de los padres

    ère et l'adolescent partageaient des perceptions similaires, tandis qu'une différence significative a émergé entre la mère et l'enfant. Un plus grand niveau de congruence perceptuelle entre les adolescents et les parents a été trouvé dans les familles d'accueil. Des différences entre les sexes ont aussi apparu: en comparaison aux pères, les mères ont expérimenté une communication plus ouverte avec leurs enfants et les adolescents, surtout les filles, communiquaient mieux avec leurs mères qu'avec leurs pères dans les trois groupes familiaux. Son escasos los estudios que se han propuesto comparar cómo los padres e hijos pertenecientes a diferentes estructuras familiares afrontan los retos que impone la transición a la adolescencia; en particular, pocos estudios comparan las familias adoptivas y las que ejercen el cuidado temporal. Para subsanar parcialmente esta deficiencia, los propósitos principales de el presente estudio fueron verificar si difiere la comunicación padres-hijos entre familias que ejercen cuidado temporal, aquéllas adoptivas entre países, y biológicas de acuerdo con el sexo del adolescente, y comparar las percepciones de los padres y de los adolescentes en cuanto a la comunicación padres-hijo. Los datos se analizaron en dos niveles: un nivel de generaciones (las percepciones del adolescente y de sus padres entre los tres grupos de familias) y un nivel de díadas (las percepciones madre-hijo y padre-hijo). Doscientas setenta y seis familias italianas con adolescentes entre 11 y 17 años de edad (81 familias de cuidado temporal, 98 adoptivas internacionalmente y 97 biológicas) constituyeron la muestra. Los participantes (madres, padres e hijos) respondieron a un cuestionario que incluía la Escala de Comunicación Padre-Adolescente (Barnes & Olson, 1985 ). Los resultados resaltan más dificultades en la comunicación padres-hijo en las familias que ejercen cuidado temporal, tanto desde la perspectiva del adolescente como de los padres

    astronomers from Unione Astrofili Italiana. To honor her professional achievements, an asteroid was named for her (11695 Mattei). She always felt that these awards honored not just of her own work, but also the contributions of the members and observers who make up the AAVSO community. Janet Mattei left a very different AAVSO than the one she took over in 1973. From 150,000 observations arriving annually and being handled on paper, now 500,000 arrive each year and are mostly processed and posted automatically. The association has a substantial endowment and owns its headquarters building in Cambridge, Massachusetts. The historical archive has been put into usable form, following two multi-year investments in digitization and validation. The activities of the AAVSO have been extended to include notifying space and ground observatories that particular objects are erupting and to capturing short-lived gamma ray burst afterglows. The organization's ties to those with similar missions around the world have been strengthened and, increasingly, the AAVSO's International Variable Star Database incorporates their data. Janet's final illness was followed, through email bulletins, by hundreds of her friends and colleagues around the world. Characteristically, during a remission-and-recovery time between treatments, Janet reached out by phone and email to many of her AAVSO associates and friends, and resumed her habit of sending appropriate cards for special occasions. The more than 200 email "memoriam" notes posted on the AAVSO web site after her death show that all who knew her, even if only briefly, considered her a friend, a mentor, or a fine example of a scientist and leader.
