    The Campi Flegrei Caldera near Naples, Italy, is arguably one of the world's prime examples of volcanic hazard in a heavily populated area. Over the last centuries the ground of the caldera went through cyclical phases of inflation and deflation. The inflation phase consists of rapid vertical ground movements associated with the emission of volcanic gases marked by a strong magmatic component. Such deformations are suggested to be caused by pulses of CO2-rich fluids injected into the caldera's shallow hydrothermal system or by the intrusion of magmatic bodies at shallow depths. We show that since 1945 the uplift crises occurring at the Campi Flegrei Caldera are caused by large regional earthquakes. Our results point out that maximum uplift rates in the caldera take place about three years after the occurrence of large earthquakes that imposed a log10(PGA[cm s-2]) greater than 0.18. These observations are supported by forward seismic simulations and with a semi-quantitative statistical analysis of ground surface displacements and Peak Ground Accelerations (PGA). Our proposed geomechanical model integrates and simplifies previous empirical concepts of upwelling fluids that pressurize the region beneath the Campi Flegrei causing ground surface uplift. Numerical simulations indicate that passing seismic body waves impose high dynamic strains at the upper boundary of the deep magma reservoir as well as at the brittle/ductile transition at about 3 km depth. Such dynamic strains induce short-lived brittle failure in nominally ductile regions causing the release of magmatic fluids. The approximately 3-years time lag between the earthquake and maximum surface uplift reflects the time during which the lithostatically pressured fluids ascend through hot, nominally ductile lithologies without expanding. After passing the brittle/ductile transition at ~3 km depth the H2O-CO2 mixture can expand and phase-separate, pressurizing the subsurface. This leads to a rapid ground uplift

    Knowledge of permeability is of paramount importance for understanding the evolution of magma degassing during pre-, syn- and post-eruptive volcanic processes. Most permeability estimates existing to date refer to magmas of calc-alkaline compositions. We report here the preliminary results of permeability measurements performed on alkali-trachyte products erupted from the Campanian Ignimbrite (CI) and Monte Nuovo (MTN), two explosive eruptions from Campi Flegrei (CF), an active, hazardous caldera west of Naples, Southern Italy. Darcian (viscous) permeability spans a wide range between 10^-11 and 10^-14 m^2. We observe that the most permeable samples are the scoria clasts from the upper units of MTN; pumice samples from the Breccia Museo facies of CI are instead the least permeable. Non-Darcian (inertial) permeability follows the same trend as Darcian permeability. The first implication of this study is that porosity in alkaline as well as calc-alkaline magmas does not exert a first order control on permeability (e.g. the MTN samples are the most permeable but not the most porous). Second, sample geometry exhibits permeability anisotropy (higher permeability in the direction of vesicle elongation), suggesting stronger degassing in the vertical direction in the conduit. In addition, inertial effects are higher across the sample. As inertial effects are potentially generated by tortuosity (or tortuous vesicle paths), tortuosity is likely higher horizontally than vertically in the conduit. Finally, the measured CF permeability values overlap with those of rhyolitic pumice clasts from the Kos Plateau Tuff (Bouvet de Maisonneuve et al., 2009), together with CI one of the major Quaternary explosive eruptions of the Mediterranean region. This indicates that gas flow is strongly controlled by the geometry of the porous media, which is generated by the bubble dynamics during magma ascent. Therefore, permeability will depend on composition through the rheological properties

    Full Text Available Campi Flegrei is a unique volcanic region located near Naples, Italy. Anomalous crustal movements at Pozzuoli in Campi Flegrei have been documented since the Roman period. The movements were gradual and have continued to the present, occasionally accompanying swarms of local earthquakes and volcanic eruptions. Generally the movements proceed with low seismicity. After the 1538 eruption of Monte Nuovo, Pozzuoli had subsided monotonously, but it changed to uplift abruptly in 1969. The uplift accelerated in 1983 and 1984 reaching more than 2 m, and thereafter began to subside. Many discussions of this event have been published. In Japan, we have examples of deformations similar to those at Campi Flegrei, mainly in volcanic areas, and rarely in non-volcanic areas. The former includes Iwojima, Miyakejima and Aira caldera while the latter is represented by Cape Omaezaki. Iwojima is a volcano island, and its secular uplifts since the 18th century are recognized as an unusual event. Miyakejima volcano and Aira caldera exhibited anomalous movements with low seismicity after their eruptions. Cape Omaezaki is not situated in volcanic zone but near a subduction zone, and gradually and continuously subsides as a precursor to a large earthquake. In such cases as Campi Flegrei and the Japanese localities, we would question whether the deformations are accompanied by normal seismicity or low seismicity. To examine quantitatively the relationship between seismicity and related deformation, seismic efficiency is generally useful. The crustal deformations in all the regions cited above are characterized by exceptionally low seismic efficiencies. In the present paper, the deformations at Pozzuoli and Iwojima are mainly described and a comparative discussion among these and other localities in Japan is supplemented. It is concluded that such anomalous phenomena in volcanic areas are attributable to peculiar rheological aspects of the material composing the local

    After the large-scale event of Neapolitan Yellow Tuff ( 15 ka B.P.), intense and mostly explosive volcanism has occurred within and along the boundaries of the Campi Flegrei caldera (Italy). Eruptions occurred closely spaced in time, over periods from a few centuries to a few millennia, and were alternated with periods of quiescence lasting up to several millennia. Often events also occurred closely in space, thus generating a cluster of events. This study had two main objectives: (1) to describe the uncertainty in the geologic record by using a quantitative model and (2) to develop, based on the uncertainty assessment, a long-term subdomain specific temporal probability model that describes the temporal and spatial eruptive behavior of the caldera. In particular, the study adopts a space-time doubly stochastic nonhomogeneous Poisson-type model with a local self-excitation feature able to generate clustering of events which are consistent with the reconstructed record of Campi Flegrei. Results allow the evaluation of similarities and differences between the three epochs of activity as well as to derive eruptive base rate of the caldera and its capacity to generate clusters of events. The temporal probability model is also used to investigate the effect of the most recent eruption of Monte Nuovo (A.D. 1538) in a possible reactivation of the caldera and to estimate the time to the next eruption under different volcanological and modeling assumptions.

    Campi Flegrei is an active volcanic area situated in the Campanian Plain (Italy) and dominated by a resurgent caldera. The great majority of past eruptions have been explosive, variable in magnitude, intensity, and in their vent locations. In this hazard assessment study we present a probabilistic analysis using a variety of volcanological data sets to map the background spatial probability of vent opening conditional on the occurrence of an event in the foreseeable future. The analysis focuses on the reconstruction of the location of past eruptive vents in the last 15 ka, including the distribution of faults and surface fractures as being representative of areas of crustal weakness. One of our key objectives was to incorporate some of the main sources of epistemic uncertainty about the volcanic system through a structured expert elicitation, thereby quantifying uncertainties for certain important model parameters and allowing outcomes from different expert weighting models to be evaluated. Results indicate that past vent locations are the most informative factors governing the probabilities of vent opening, followed by the locations of faults and then fractures. Our vent opening probability maps highlight the presence of a sizeable region in the central eastern part of the caldera where the likelihood of new vent opening per kilometer squared is about 6 times higher than the baseline value for the whole caldera. While these probability values have substantial uncertainties associated with them, our findings provide a rational basis for hazard mapping of the next eruption at Campi Flegrei caldera.

    The Campanian volcanic area has a huge geothermal potential (Carlino et al., 2012), similar to the Larderello-Radicondoli-Amiata region, in Tuscany (Italy), which has been the first site in the World exploited for electric production. Recently, the Campi Flegrei Deep Drilling Project (CFDDP), sponsored by ICDP and devoted to understand and mitigate the extreme volcanic risk in the area, has also risen new interest for geothermal exploration in several areas of Italy. Following the new Italian regulations which favour and incentivise innovative pilot power plants with zero emission, several geothermal projects have started in the Campania Region, characterized by strict cooperation among large to small industries, Universities and public Research Centers. INGV department of Naples (Osservatorio Vesuviano) has the technical/scientific leadership of such initiatives. Most of such projects are coordinated in the framework of the Regional District for Energy, in which a large part is represented by geothermal resource. Leading geothermal projects in the area include 'FORIO' pilot plant project, aimed to build two small (5 MWe each one) power plants in the Ischia island and two projects aimed to build pilot power plants in the Agnano-Fuorigrotta area in the city of Naples, at the easternmost part of Campi Flegrei caldera. One of the Campi Flegrei projects, 'SCARFOGLIO', is aimed to build a 5 MWe geothermal power plant in the Agnano area, whereas the 'START' project has the goal to build a tri-generation power plant in the Fuorigrotta area, fed mainly by geothermal source improved by solar termodynamic and bio-mass. Meanwhile such projects enter the field work operational phase, the pilot hole drilling of the CFDDP project, recently completed, represents an important experience for several operational aspects, which should contitute an example to be followed by the next geothermal activities in the area. It has been furthermore a source of valuable data for geothermal

    Volcanic unrest at Campi Flegrei caldera, Southern Italy, is characterized by episodes of ground deformation, seismicity, and enhanced fumarolic activity; whether its origin is purely hydrothermal or magmatic is highly debated. We have identified ground deformation patterns in strainmeter records from a heightened unrest period in late 2006, closely resembling synthetic signals from numerical simulations of shallow magma chamber replenishment and mixing. Together with other recent findings, our results depict a situation whereby periodic arrivals of deep magma feed a shallow intrusion at 3-4 km depth. These results suggest that the analysis of strainmeter records, coupled with advanced numerical simulations of magma dynamics, could lead to new approaches in imaging subsurface dynamic processes in volcanic areas.

    The accuracy of automatic procedures for detecting seismic events and locating their sources is influenced by several factors such as errors in picking seismic phases often buried in the high-level ambient noise, network geometry and modelling errors. fundamental objective is the improvement of these procedures by developing accurate algorithms for quasi-real time seismic data processing, easily managed in observatory practice. Recently a robust automatic procedure has been implemented for detecting, onset picking and identifying signal phases in continuous seismic signal with an application at the seismicity recorded at Campi Flegrei Caldera (Italy) during the 2006 ground uplift (Ciaramella et al. 2011). An Independent Component Analysis based approach for the Blind Source Separation of convolutive mixtures (CICA) has been adopted to obtain a clear separation of low-energy Long Period events (LPs) from the high-level ambient noise allowing to compile a complete seismic catalogue and better quantify the seismic energy release. In this work, we apply CICA at the seismic signal continuously recorded during the entire 2006 at Campi Flegrei. First, we have performed tests on synthetic data in order to improve the reliability and the accuracy of the procedure. The performance test using very noisy synthetic data shows that the method works even in case of very poor quality data characterized by very low signal to noise ratio (SNR). Second, we have improved CICA automatic procedure recovering the information on the amplitudes of the extracted independent components. This is crucial for further analysis, starting from a prompt estimate of magnitude/energy of the highlighted events. Data used for the present analysis were collected by four broadband three-component seismic stations (ASB2, AMS2, TAGG, BGNG) belonging to the Campi Flegrei seismic monitoring network, managed by the 'Istituto Nazionale di Geofisica e Vulcanologia-Osservatorio Vesuviano (INGV-OV)' (see for

    Thermo-mineral springs are widely spread over the volcanic areas of Campi Flegrei and Ischia, and on the western side of the city of Naples. Their use has, since long, been known by local inhabitants because they were one of the main curative therapies in the past. The fortune and use of the thermal springs have been affected by the volcanic eruptions that occurred in different times in these areas. The exploitation of geothermal springs in Campi Flegrei suffered a decisive decline after the eruption of Monte Nuovo in 1538. Conversely, after that eruption, in Ischia Island there was a progressive increase of the use of thermal spring therapy. The use of geothermal resources for electric generation has not been implemented in Campi Flegrei because of the difficulty in using hypersaline fluids, whereas in Ischia, local authorities preferred only the development of touristic activity based on geothermal springs.

    Caldera-forming eruptions, during which large volumes of magma are explosively evacuated into the atmosphere from shallow crustal reservoirs, are one of the most hazardous natural events on Earth. The Campanian Ignimbrite (CI; Campi Flegrei, Italy) represents a classical example of such events, producing a voluminous pyroclastic sequence of trachytic to phonolitic magma that covered several thousands of squared kilometers in the south-central Italy around 39 ka ago. The CI deposits are known for their remarkable geochemical gradients, attributed to eruption from a vertically zoned magma chamber. We investigate the relationships between such chemical zoning and the crystallinity variations observed within the CI pyroclastic sequence by combining bulk-rock data with detailed analyses of crystals and matrix glass from well-characterized stratigraphic units. Using geothermometers and hygrometers specifically calibrated for alkaline magmas, we reconstruct the reservoir storage conditions, revealing the presence of gradients in temperature and magma water content. In particular, we observe a decrease in crystallinity and temperature and an increase in magma evolution and water content from the bottom to the top of the magma chamber. We interpret these features as the result of protracted fractional crystallization leading to the formation of a cumulate crystal mush at the base of the eruptible reservoir, from which highly evolved, crystal-poor, water-rich and relatively cold melts were separated. The extracted melts, forming a buoyant, easily eruptible cap at the top of the magma chamber, fed the initial phases of the eruption, until caldera collapse and eruption of the deeper more crystalline part of the system. This late-erupted, crystal-rich material represents remobilized portions of the cumulate crystal mush, partly melted following hotter recharge. Our interpretation is supported by: 1) the positive bulk-rock Eu anomalies and the high Ba and Sr contents observed in

    Calderas are collapse structures related to the emptying of magmatic reservoirs, often associated with large eruptions from long-lived magmatic systems. Understanding how magma is transferred from a magma reservoir to the surface before eruptions is a major challenge. Here we exploit the historical, archaeological and geological record of Campi Flegrei caldera to estimate the surface deformation preceding the Monte Nuovo eruption and investigate the shallow magma transfer. Our data suggest a progressive magma accumulation from ~1251 to 1536 in a 4.6 ± 0.9 km deep source below the caldera centre, and its transfer, between 1536 and 1538, to a 3.8 ± 0.6 km deep magmatic source ~4 km NW of the caldera centre, below Monte Nuovo; this peripheral source fed the eruption through a shallower source, 0.4 ± 0.3 km deep. This is the first reconstruction of pre-eruptive magma transfer at Campi Flegrei and corroborates the existence of a stationary oblate source, below the caldera centre, that has been feeding lateral eruptions for the last ~5 ka. Our results suggest: 1) repeated emplacement of magma through intrusions below the caldera centre; 2) occasional lateral transfer of magma feeding non-central eruptions within the caldera. Comparison with historical unrest at calderas worldwide suggests that this behavior is common.

    Campi Flegrei (Italy) is a nested caldera and together with Vesuvius is one of the Italian GEO Geohazard Supersites (GSNL). The area is characterized by one of the highest volcanic hazard of the world, due to the very high density of inhabitants (1800/km²), the persistent activity of the system and the explosive character of volcanism. A major unrest episode took place in 1982-84, when the town of Pozzuoli, located at the caldera center, was uplifted by 1.80 m. Minor uplifts of few centimeters, seismic swarms and degassing episodes took place in 1989, 2000 and 2004-06. Since 2005 Campi Flegrei is uplifting, reaching a ground velocity of 9 cm/yr in 2012, showing that the caldera is in a critical state on the verge of instability. In this work, we present results from SAR Interferometry and geodetic data modelling at Campi Flegrei in the framework of the EU's FP7 MED-SUV Project. We exploit two COSMO-SkyMed data sets to map the deformation field during 2011-2013. The spatial distributions of the cumulative displacement from COSMO-SkyMed ascending/descending orbits show similar behaviors, confirming the bell-shaped pattern of the deformation at least within the inner rim of the caldera. The resulting data, together with GPS data from the Neapolitan Volcanoes Continuous GPS network (NeVoCGPS) is fitted through a geophysical inversion process using finite element forward models to account for the 3D heterogeneous medium. The best fit model is a north dipping mixed-mode dislocation source lying at ~5 km depth. The driving mechanism is ascribable to magma input into the source of the large 1982-1984 unrest (since similar source characteristics were inferred) that generates initial inflation followed by additional shear slip accompanying the extension of crack tips. The history and the current state of the system indicate that Campi Flegrei is able to erupt again. Constraining the defomation source may have important implications in terms of civil protection and the

    Large collapse calderas are associated with exceptionally explosive volcanic eruptions, which are capable of triggering a global catastrophe second only to that from a giant meteorite impact. Therefore, active calderas have attracted significant attention in both scientific communities and governmental institutions worldwide. One prime example of a large collapse caldera can be found in southern Italy, more precisely in the northern Bay of Naples within the Campi Flegrei Volcanic Area. The Campi Flegrei caldera covers an area of approximately 200 km² defined by a quasi-circular depression, half onland, half offshore. It is still under debate whether the caldera formation was related to only one ignimbritic eruption namely the Neapolitan Yellow Tuff (NYT) eruption at 15 ka or if it is a nested-caldera system related to the NYT and the Campanian Ignimbrite eruption at 39 ka. During the last 40 years, the Campi Flegrei caldera has experienced episodes of unrest involving significant ground deformation and seismicity, which have nevertheless not yet led to an eruption. Besides these short-term episodes of unrest, long-term ground deformation with rates of several tens of meters within a few thousand years can be observed in the central part of the caldera. The source of both short-term and long-term deformation is still under debate and possibly related to a shallow hydrothermal system and caldera resurgence attributed to a deeper magma chamber, respectively. Understanding the mechanisms for unrest and eruptions is of paramount importance as a future eruption of the Campi Flegrei caldera would expose more than 500,000 people to the risk of pyroclastic flows. This study is based on a dense grid (semi-3D) of high-resolution multi-channel seismic profiles acquired in the offshore sector of the Campi Flegrei caldera. The seismic lines show evidence for the escape of fluids and/or gases along weak zones such as faults, thereby supporting the existence of a hydrothermal

    We describe the results from a combined controlled source audio magnetotelluric (CSAMT) and natural source magnetotelluric (MT) survey carried out in the Solfatara-Pisciarelli (S-P) area, located in the central part of the Campi Flegrei (CF) composite caldera, west of Naples, Southern Italy. The S-P area represents the most active zone within the CF caldera, in terms of hydrothermal manifestations and local seismicity. Since 1969, the CF caldera is experiencing ground deformation, seismicity and geochemical fluid changes, which are particularly evident in the S-P area. A 1 km long, nearly W-E directed CSAMT-MT profile crossing the fumarole field was carried out in the S-P area with the aim of deducting a resistivity model of the structural setting of the hydrothermal system in the first 3 km depth. An interpretation of the modelled section across the profile is given in this paper, taking advantage from already existing seismic, gravity and geochemical data in the same area. Three well distinct zones have been outlined. The first zone is a very shallow, electrically conductive body localized beneath the westernmost segment of the profile, which, within a short distance of about 100 m, dips westwards from near surface down to some hundred metres in depth. Mostly accounting for the very low resistivity (1-10 Ω m) and the exceedingly high values of vP/vS (> 4), this shallow zone has been ascribed to a water-saturated, high-pressurized geothermal reservoir. The second zone, which has been localized below the west-central portion of the CSAMT-MT transect, appears as a composite body made up of a nearly vertical plumelike structure that escapes at about 2.25 km depth from the top edge of the east side of a presumably horizontal platelike body. The plumelike structure rises up to the free surface in correspondence of the fumarole field, whereas the platelike structure deepens at least down to the 3 km of maximum exploration depth. The combined interpretation of

    Based on their δ 34S signature, sulfate minerals and native sulfur around fumaroles and hot water pools from the Campi Flegrei volcanic area derive from supergenic oxidation of volcanic H 2S. Their mean δ 34S value (-0.2±1.7‰) matches with that of fumarolic H 2S at Solfatara (-0.3±0.3‰), as well as with the δ 34S of +1.4‰ obtained for total sulfur in fresh trachyte from the area. All δ 34S values indicate a mostly deep-seated origin for sulfur. Thermal waters were analysed for major and minor chemistry and for oxygen, hydrogen and sulfur isotope compositions. Pools at Pisciarelli are filled with evaporated meteoric water heated by rising (magmatic) gases. The water δ 18O (+3.8±1.3‰) and δ 2H (+6.5±2.2‰) values in these steam-heated waters are controlled by mixing and evaporation effects, and the δ 34S value of dissolved sulfate (-1.3±0.3‰) basically agrees with supergenic oxidation of deep-seated H 2S as the major source of sulfur. Instead, water from thermal springs and wells elsewhere in the Campi Flegrei appears to be a mixture between dilute meteoric and saline marine components. The latter may be local seawater from the bay of Pozzuoli. The δ 18O and δ 2H values of waters sampled during 1993-1994 range from -5.6 to +0.3‰ and from -33 to -3.4‰, respectively. The δ 34S values of dissolved sulfate range between -0.1 and +19.5‰. In general, sulfate is probably derived essentially from two sources, both within the volcanic cover, i.e., oxidation/dissolution of pyrite and anhydrite, and marine water. An occasional source of water and sulfate is represented by (magmatic) gases, which directly interact with shallow meteoric water as in the case of the Hotel Tennis well yielding steam-heated water with δ 18O=-1.5±0.2‰, δ 2H=-17±1‰ and δ 34S=-0.1‰.

    Pyroclastic density currents (PDCs) are gravity-driven hot mixtures of gas and volcanic particles which can propagate at high speed and cover distances up to several tens of kilometers around a given volcano. Therefore, they pose a severe hazard to the surroundings of explosive volcanoes able to produce such phenomena. Despite this threat, probabilistic volcanic hazard assessment (PVHA) of PDCs is still in an early stage of development. PVHA is rooted in the quantification of the large uncertainties (aleatory and epistemic) which characterize volcanic hazard analyses. This quantification typically requires a big dataset of hazard footprints obtained from numerical simulations of the physical process. For PDCs, numerical models range from very sophisticated (not useful for PVHA because of their very long runtimes) to very simple models (criticized because of their highly simplified physics). We present here a systematic and robust validation testing of a simple PDC model, the energy cone (EC), to unravel whether it can be applied to PVHA of PDCs. Using past PDC deposits at Somma-Vesuvius and Campi Flegrei (Italy), we assess the ability of EC to capture the values and variability in some relevant variables for hazard assessment, i.e., area of PDC invasion and maximum runout. In terms of area of invasion, the highest Jaccard coefficients range from 0.33 to 0.86 which indicates an equal or better performance compared to other volcanic mass-flow models. The p values for the observed maximum runouts vary from 0.003 to 0.44. Finally, the frequencies of PDC arrival computed from the EC are similar to those determined from the spatial distribution of past PDC deposits, with high PDC-arrival frequencies over an ˜8-km radius from the crater area at Somma-Vesuvius and around the Astroni crater at Campi Flegrei. The insights derived from our validation tests seem to indicate that the EC is a suitable candidate to compute PVHA of PDCs.

    The partitioning of trace elements between crystals and melts provides an important petrogenetic tool for understanding magmatic processes. We present trace element partition coefficients measured between clinopyroxene phenocrysts and trachy-phonolitic magmas at the Campi Flegrei (Italy), whose late Quaternary volcanism has been characterized by two major caldera-forming events (Campanian Ignimbrite at ~ 39 ka, and Neapolitan Yellow Tuff at ~ 15 ka). Our data indicate that the increase of trivalent rare earth elements and yttrium into the crystal lattice M2 site is facilitated by the charge-balancing substitution of Si4 + with Al3 + on the tetrahedral site. Higher concentrations of tetravalent and pentavalent high field strength elements on the M1 site are also measured when the average charge on this site is increased by the substitution of divalent cations by Alvi. In contrast, due to these charge balance requirements, divalent transitional elements become less compatible within the crystal lattice. On the basis of the lattice strain theory, we document that the incorporation of rare earth elements and yttrium in clinopyroxene is influenced by both compositional and physical parameters. Data from this study allow to update existing partitioning equations for rare earth elements in order to construct a self-consistent model for trachy-phonolitic magmas based on the lattice strain theory. The application of this model to natural products from the Campanian Ignimbrite, the largest caldera-forming eruption at the Campi Flegrei, reveals that the complex rare earth element pattern recorded by the eruptive products can be successfully described by the stepwise fractional crystallization of clinopyroxene and feldspar where the clinopyroxene-melt partition coefficient changes progressively as a function of the physicochemical conditions of the system.

    Deformation of the ground surface in volcanic areas is generally recognized as a reliable indicator of unrest, possibly resulting from the intrusion of fresh magma within the shallow rock layers. The intrusion process is usually represented by a deformation source such as an ellipsoidal pressurized cavity, embedded within a homogeneous and elastic half-space. Similar source models allow inferring the depth, the location and the (incremental) volume of the intrusion, which are very important parameters for volcanic risk implications. However, assuming a homogeneous and elastic rheology and, assigning a priori the shape and the mechanism of the source (within a very restricted 'library' of available solutions) may bias considerably the inference of source parameters. In complete generality, any point source deformation, including overpressure sources, may be described in terms of a suitable moment tensor, while the assumption of an overpressure source strongly restricts the variety of allowable moment tensors. In particular, by assuming a pressurized cavity, we rule out the possibility that either shear failure may precede magma emplacement (seismically induced intrusion) or may accompany it (mixed tensile and shear mode fracture). Another possibility is that a pre-existent weakness plane may be chosen by the ascending magma (fracture toughness heterogeneity). We perform joint inversion of levelling and EDM data (part of latter are unpublished), collected during the 1982-84 unrest at Campi Flegrei caldera: a 43% misfit reduction is obtained for a general moment source if the elastic heterogeneities computed from seismic tomography are accouted for. The inferred source is at 5.2 km depth but cannot be interpreted as a simple pressurized cavity. Moreover, if mass conservation is accounted for, magma emplaced within a shallow source must come from a (generally deeper) reservoir, which is usually assumed to be deep enough to be simply neglected. At Campi Flegrei, seismic

    Campi Flegrei is an active volcanic complex located in the greater Naples area, which has produced more than 50 eruptions over the past 60,000 years. These have ranged from small eruptions such as Monte Nuovo eruption of 1538 CE to extremely large eruptions such as the Campanian Ignimbrite (150-200 DRE; Barbieri et al., 1978). The volcanic field includes the mainland area located to the west of Naples and also the two islands of Ischia and Procida. The volcanic products range from basalts to shoshonitic phonolites and trachytes, with the more evolved magmas being more abundant. Three eruptive units from Procida Island have been studied to observe geochemical trends over time within a small area and to better understand magmatic processes between monogenetic eruptions. Juvenile samples from Pozzo Vecchio, Breccia Museo, and Solchiara were collected to examine the geochemistry of the mineral phases present and melt inclusions (MIs) found within the phenocrysts. Solchiara contained phenocrysts of olivine and clinopyroxene, whereas Breccia Museo and Pozzo Vecchio samples contained clinopyroxene and sanidine as the dominant phenocryst phases. Melt inclusions from Solchiara have narrow compositional ranges in major and trace elements (i.e., CaO, TiO2, Zr, Dy, La) over a large range in SiO2 contents (47 to 55 wt%) while MI from the Breccia Museo have a limited range of SiO2 contents (57 to 61 wt%) with a wider range for major and trace elements (i.e., FeO, Al2O3, CaO, La, Th, Rb). Pozzo Vecchio MI from clinopyroxene and sanidine define different chemical compositions, but petrographic evidence does not suggest a xenocrystic origin for either mineral phase. This suggests that Pozzo Vecchio is the result of magma mixing. Modeling of fractional crystallization of olivine, clinopyroxene, and sanidine are capable of producing most of the trends in major and trace elements between the most primitive samples to the most evolved samples.

    Campi Flegrei caldera, Italy, located along the Bay of Naples, has a long history of significant vertical deformation, with the most recent large uplift (>1.5m) occurring in 1983-1984. Each episode of uplift has been followed by a period of subsidence that decreases in rate with time and may be punctuated by brief episodes of lesser uplift. The large amplitude of the major uplifts that occur without volcanic activity, and the subsequent subsidence has been argued as evidence for hydrothermal amplification of any magmatic source. The later subsidence and its temporal decay have been argued as due to diffusion of the pressurized caldera fill material into the less porous surrounding country rock. We present satellite synthetic aperture radar (SAR) interferometry (InSAR) time series analysis of ERS and Envisat data from the European Space Agency, based on exploiting the Small Baseline Subset (SBAS) approach [Berardino et al., 2002]; this allows us to generate maps of relative surface deformation though time, beginning in 1992 through 2007, that are relevant to both ascending and descending satellite orbits. The general temporal behavior is one of subsidence punctuated by several lesser uplift episodes. The spatial pattern of deformation can be modeled through simple inflation/deflation sources in an elastic halfspace. Given the evidence to suggest that fluids may play a significant role in the temporal deformation of Campi Flegrei, rather than a purely magmatic or magma chamber-based interpretation, we model the temporal and spatial evolution of surface deformation as a hydrothermal fluid flow process. We use the TOUGH2-BIOT2 set of numerical codes [Preuss et al., 1999; Hsieh, 1996], which couple multi-phase (liquid-gas) and multi-component (H2O-CO2) fluid flow in a porous or fractured media with plane strain deformation and fluid flow in a linearly elastic porous medium. We explore parameters related to the depth and temporal history of fluid injection, fluid

    The Campi Flegrei volcanic district (Naples region, Italy) is a 12-km-wide, restless caldera system that has erupted at least six voluminous ignimbrites during the late Pleistocene, including the >300 km3 Campanian ignimbrite (CI) which originated from the largest known volcanic event of the Mediterranean region. The Breccia Museo (BM), a petrologically heterogeneous and stratigraphically complex volcanic deposit extending over 200 km2 in close proximity to Campi Flegrei, has long remained contentious regarding its age and stratigraphic relation to the CI. Here, we present crystallization and eruption ages for BM plutonic ejecta clasts that were determined via uranium decay series and (U-Th)/He dating of zircon, respectively. Despite mineralogical and textural heterogeneity of these syenitic clasts, their U-Th zircon rim crystallization ages are indistinguishable with an average age of 49.7 ± 2.5 ka (2σ errors; mean square of weighted deviates MSWD = 1.2; n = 34). A subset of these crystals was used to obtain disequilibrium-corrected (U-Th)/He zircon ages which average 41.7 ± 1.8 ka (probability of fit P = 0.54; n = 15). This age closely overlaps with published CI 40Ar/39Ar eruption ages (40.6 ± 0.1 ka) after recalibration to recently revised flux monitor ages. Concordant eruption ages for BM and CI agree with previous chemostratigraphic and paleomagnetic correlations, suggesting their origin from the same eruption. However, they are at variance with recalibrated 40Ar/39Ar ages which have BM postdate CI by 3 ± 1 ka. BM syenites show similar geochemical and Sr-Nd isotopical features of pre-caldera rocks erupted between 58 and 46 ka, but are distinctive from subsequent caldera-forming magmas. Energy-constrained assimilation and fractional crystallization modeling of Nd-Sr isotopic data suggests that pre-caldera magmas formed a carapace of BM-type intrusions in a mid-crust magma chamber (≥8 km depth) shielding the younger CI magma from contamination by

    Full Text Available Employing 3D finite element method, we develop an algorithm to calculate gravity changes due to pressurized sources of any shape in elastic and inelastic heterogeneous media. We consider different source models, such as sphere, spheroid and sill, dilating in elastic media (homogeneous and heterogeneous and in elasto-plastic media. The models are oriented to reproduce the gravity changes and the surface deformation observed at Campi Flegrei caldera (Italy, during the 1982-84 unrest episode. The source shape and the characteristics of the medium have great influence in the calculated gravity changes, leading to very different values for the source densities. Indeed, the gravity residual strongly depends upon the shape of the source. Non negligible contributions also come from density and rigidity heterogeneities within the medium. Furthermore, if the caldera is elasto-plastic, the resulting gravity changes exhibit a pattern similar to that provided by a low effective rigidity. Even if the variation of the source volumes is quite similar for most of the models considered, the density inferred for the source ranges from ? 400 kg/m3 (supercritical water to ? 3300 kg/m3 (higher than trachytic basalts, with drastically different implications for risk assessment.

    Lithospheric VS models are defined in the Campi Flegrei District (southern Italy) through the non-linear inversion of the group velocity dispersion curves of fundamental-mode Rayleigh waves extracted from ambient noise cross-correlations between two receivers, and the regional group and phase velocities of the Italian cellular lithospheric model (1° × 1° cells). Four paths are investigated, of which one (ISCHIA-MIS) across two adjoining cells. The distribution of VS shows a pyroclastic covering with VS increasing from 0.3-0.7 km/s to 2.1 km/s. It rests on a lava or carbonate basement, about 5-6 km thick, with VS increasing from 2.1 km/s to 3.1 km/s at about 2 km of depth and rising to ∼0.6 km towards the island of Procida. A metamorphic layer is detected at an average depth of 7.7 km with VS of 3.8-3.9 km/s, about 5 km thick, overlying a low velocity layer (VS of 3.5 km/s) at about 11-12 km of depth. The VS model along the ISCHIA-MIS path, as average of the models obtained by combining local and regional dispersion data of the two adjoining cells, is well consistent with the other paths. The Moho discontinuity is retrieved at about 23 km of depth with VS of 4.2 km/s.

    The chemical composition of volatile organic compounds (VOCs) in soil gases from the Solfatara crater (Campi Flegrei, Southern Italy) was analyzed to investigate the effects of biogeochemical processes occurring within the crater soil on gases discharged from the hydrothermal reservoir and released into the atmosphere through diffuse degassing. In this system, two fumarolic vents (namely Bocca Grande and Bocca Nuova) are the preferential pathways for hydrothermal fluid uprising. For our goal, the chemistry of VOCs discharged from these sites were compared to that of soil gases. Our results highlighted that C4-C9 alkanes, alkenes, S-bearing compounds and alkylated aromatics produced at depth were the most prone to degradation processes, such as oxidation-reduction and hydration-dehydration reactions, as well as to microbial activity. Secondary products, which were enriched in sites characterized by low soil gas fluxes, mostly consisted of aldheydes, ketons, esters, ethers, organic acids and, subordinately, alcohols. Benzene, phenol and hydrofluorocarbons (HCFCs) produced at depth were able to transit through the soil almost undisturbed, independently on the emission rate of diffuse degassing. The presence of cyclics was possibly related to an independent low-temperature VOC source, likely within sedimentary formations overlying the hydrothermal reservoir. Chlorofluorocarbons (CFCs) were possibly due to air contamination. This study demonstrated the strict control of biogeochemical processes on the behaviour of hydrothermal VOCs that, at least at a local scale, may have a significant impact on air quality. Laboratory experiments conducted at specific chemical-physical conditions and in presence of different microbial populations may provide useful information for the reconstruction of the degradation pathways controlling fate and behaviour of VOCs in the soil.

    Today hundreds of thousands people live inside the Campi Flegrei caldera (Italy) and in the adjacent part of the city of Naples making a future eruption of such volcano an event with huge consequences. Very high risks are associated with the occurrence of pyroclastic density currents (PDCs). Mapping of background or long-term PDC hazard in the area is a great challenge due to the unknown eruption time, scale and vent location of the next event as well as the complex dynamics of the flow over the caldera topography. This is additionally complicated by the remarkable epistemic uncertainty on the eruptive record, affecting the time of past events, the location of vents as well as the PDCs areal extent estimates. First probability maps of PDC invasion were produced combining a vent-opening probability map, statistical estimates concerning the eruptive scales and a Cox-type temporal model including self-excitement effects, based on the eruptive record of the last 15 kyr. Maps were produced by using a Monte Carlo approach and adopting a simplified inundation model based on the "box model" integral approximation tested with 2D transient numerical simulations of flow dynamics. In this presentation we illustrate the independent effects of eruption scale, vent location and time of forecast of the next event. Specific focus was given to the remarkable differences between the eastern and western sectors of the caldera and their effects on the hazard maps. The analysis allowed to identify areas with elevated probabilities of flow invasion as a function of the diverse assumptions made. With the quantification of some sources of uncertainty in relation to the system, we were also able to provide mean and percentile maps of PDC hazard levels.

    To improve the knowledge of the shallowest subsurface of Campi Flegrei caldera, a 3-D P wave attenuation tomography of the area was performed. We analyzed about 18,000 active seismic traces, which provided a data set of 11,873 Δt* measurements, e.g., the differential travel times to quality factor ratios. These were inverted through an adapted tomographic inversion procedure. The 3-D tomographic images reveal an average QP about 70, interpreted as water-saturated volcanic and marine sediments. An arc-like, low-QP structure at 0.5-1 km depths was interpreted as a densely fractured, fluid-saturated rock volume, well matching the buried rim of Campi Flegrei caldera. The spatial distribution of high- and low-QP bodies in the inner caldera is correlated with low-Vp values and may reflect either the differences in the percentage of fluid saturation of sediments or the presence of vapor state fluids beneath fumarole manifestations.

    The Averno 2 eruption (3,700 ± 50 a B.P.) was an explosive low-magnitude event characterized by magmatic and phreatomagmatic explosions, generating mainly fall and surge beds, respectively. It occurred in the Western sector of the Campi Flegrei caldera (Campanian Region, South Italy) at the intersection of two active fault systems, oriented NE and NW. The morphologically complex crater area, largely filled by the Averno lake, resulted from vent activation and migration along the NE-trending fault system. The eruption generated a complex sequence of pyroclastic deposits, including pumice fall deposits in the lower portion, and prevailing surge beds in the intermediate-upper portion. The pyroclastic sequence has been studied through stratigraphical, morphostructural and petrological investigations, and subdivided into three members named A through C. Member A was emplaced during the first phase of the eruption mainly by magmatic explosions which generated columns reaching a maximum height of 10 km. During this phase the eruption reached its climax with a mass discharge rate of 3.2 106 kg/s. Intense fracturing and fault activation favored entry of a significant amount of water into the system, which produced explosions driven by variably efficient water-magma interaction. These explosions generated wet to dry surge deposits that emplaced Member B and C, respectively. Isopachs and isopleths maps, as well as areal distribution of ballistic fragments and facies variation of surge deposits allow definition of four vents that opened along a NE oriented, 2 km long fissure. The total volume of magma extruded during the eruption has been estimated at about 0.07 km3 (DRE). The erupted products range in composition from initial, weakly peralkaline alkali-trachyte, to last-emplaced alkali-trachyte. Isotopic data and modeling suggest that mixing occurred during the Averno 2 eruption between a more evolved, less radiogenic stored magma, and a less evolved, more radiogenic magma

    Sr-isotopic microanalysis has been performed on selected minerals from the Campi Flegrei caldera, together with Sr and Nd isotopic ratio determinations on bulk mineral and glass fractions. The aim was a better characterization of the chemically homogeneous, but isotopically distinct magmatic components which fed volcanic eruptions of the caldera over the past 5 ka, in order to enhance our knowledge about one of the most dangerous volcanoes on Earth. Information on the involved magmatic endmembers, unobtainable by analyzing the isotopic composition of whole rock samples and bulk mineral fractions, has been acquired through high-precision determination of 87Sr/86Sr on single crystals and microdrilled mineral powders. We focused our investigations on the products emplaced during the Astroni 6 eruption (4.23 cal ka BP), assumed representative of the expected event in case of renewed volcanic activity in the Campi Flegrei caldera. Data on single crystals and microdrilled mineral powders have been compared with Sr and Nd isotopic compositions of bulk mineral fractions from products emplaced during the whole Astroni activity, which included seven distinct eruptions. The 87Sr/86Sr ratios of single crystals and microdrilled mineral powders are in the 0.7060 to 0.7076 range, much wider than that of bulk mineral fractions, which range from 0.7066 to 0.7076. Moreover, the Sr isotopic ratios are inversely correlated to 143Nd/144Nd. The new data allow us to better define the magmatic endmembers involved in mingling/mixing processes that occurred prior to/during the Astroni activity. One magmatic endmember, characterized by average 87Sr/86Sr ratio of ~ 0.70750, was quite common in the past 15 ka activity of the Campi Flegrei caldera; the other, as evidenced by the isotopic composition of single feldspar and clinopyroxene crystals, is less enriched in radiogenic Sr (87Sr/86Sr ~ 0.70724). The latter is interpreted to represent a new magmatic component that entered the Campi Flegrei

    The Breccia Museo is one of the most debated volcanic formations of the Campi Flegrei volcanic district. The deposit, made up of six distinctive stratigraphic units, has been interpreted by some as the proximal facies of the major caldera-forming Campanian Ignimbrite eruption, and by others as the product of several, more recent, independent and localized events. New geochemical and chemostratigraphical data and Ar-Ar age determinations for several units of the Breccia Museo deposits (~39 ka), correlate well with the Campanian Ignimbrite-forming eruption. The chemical zoning of the Breccia Museo deposits is interpreted here to be a consequence of a three-stage event that tapped a vertically zoned trachytic magma chamber.

    Tsunami caused by underwater volcanic explosions are typically characterized by short period waves and greater dispersion compared to tsunami generated by earthquakes, and the impact in the far-field is often limited. However, the effect of dispersion is reduced for underwater explosions occurring in shallow-water environments, as the length-to-depth ratio of the waves rapidly increase, and runup inland can be locally high. This effect was particularly illustrated by the 19 m runup at Karymsky Lake, Kamchatka, in 1996 (Belousov et al., 2010; Ulvrova et al., 2014). Hazards related to underwater volcanic explosions are challenging to evaluate and might be underestimated in some cases. In this study we consider different scenarios of explosions in the offshore part of the Campi Flegrei (Phlegraean Fields) caldera in the Pozzuoli - Naples region (Tyrrhenian Sea, Italy). The onshore eruptive history of the caldera is well documented (e.g. Orsi et al., 2004), but past and future activity offshore has been rarely discussed. The probability for eruptions in the submarine part of the caldera is perhaps low (Selva et al., 2012), but scenarios of tsunamis generated by underwater explosions and their impact in the proximal field (Bay of Pozzuoli) and far field (Bay of Naples) deserve to be considered due to high population density in the adjacent coastal areas. Initial surface displacement is estimated as a function of explosion energy at a given depth. We study 17 different potential vent locations within the Pozzuoli Bay, and 3 different vent radii (200 m, 650 m and 900 m), corresponding to the three representative eruptive scenarios identified in Orsi et al. (2009) and Selva et al. (2010). We then use these sources in a Bayesian Event Tree framework, following the procedure defined in Selva et al. (2010), in order to evaluate a first order Probabilistic Hazard Analysis for this type of tsunami sources for the Gulfs of Napoli and Pozzuoli. Belousov A., Voight B., Belousova M

    The record of felt earthquakes around Naples Bay in southern Italy is probably complete since the mid-15th century. According to this record, intense earthquake swarms originating beneath Campi Flegrei, an explosive caldera located along the north coast of Naples Bay, have occurred only twice: (1) before the only historical eruption in Campi Flegrei in 1538; and (2) from mid-1983 to December 1984. Earthquake activity during the earlier period, which began at least a few years, and possibly as many as 30 years, before the 1538 eruption, damaged many buildings in the city of Pozzuoli, located near the center of Campi Flegrei. Minor seismic activity, which consisted of only a few felt earthquakes, occurred from 1970 to 1971. The second period of intense earthquake swarms lasted from mid-1983 to 1984, again damaging many buildings in Pozzuoli. Two periods of uplift along the shoreline within Campi Flegrei have also been noted since the mid-15th century: (1) during the few decades before the 1538 eruption; and (2) as two distinct episodes since 1968. Uplift of a few meters probably occurred a few decades before the 1538 eruption; uplift of as much as 3.0 m has occurred in Pozzuoli since 1968. These similarities strongly suggest that, for the first time in 440 years, the same process that caused intense local earthquake swarms and uplift in the early 1500's and led to an eruption in 1538, has again occurred beneath Campi Flegrei. Though no major seismicity or uplift has occurred since December 1984, because of the large amount of extensional strain accumulated during the past two decades, if a third episode of seismicity and rapid uplift occurs, it may lead to an eruption within several months after the resumption of activity. ?? 1991.

    Campi Flegrei (CF) is an example of an active caldera containing densely populated settlements at very high risk of pyroclastic density currents (PDCs). We present here an innovative method for assessing background spatial PDC hazard in a caldera setting with probabilistic invasion maps conditional on the occurrence of an explosive event. The method encompasses the probabilistic assessment of potential vent opening positions, derived in the companion paper, combined with inferences about the spatial density distribution of PDC invasion areas from a simplified flow model, informed by reconstruction of deposits from eruptions in the last 15 ka. The flow model describes the PDC kinematics and accounts for main effects of topography on flow propagation. Structured expert elicitation is used to incorporate certain sources of epistemic uncertainty, and a Monte Carlo approach is adopted to produce a set of probabilistic hazard maps for the whole CF area. Our findings show that, in case of eruption, almost the entire caldera is exposed to invasion with a mean probability of at least 5%, with peaks greater than 50% in some central areas. Some areas outside the caldera are also exposed to this danger, with mean probabilities of invasion of the order of 5-10%. Our analysis suggests that these probability estimates have location-specific uncertainties which can be substantial. The results prove to be robust with respect to alternative elicitation models and allow the influence on hazard mapping of different sources of uncertainty, and of theoretical and numerical assumptions, to be quantified.

    The Campi Flegrei hosts numerous monogenetic vents inferred to be younger than the 15 ka Neapolitan Yellow Tuff. Sanidine crystals from the three young Campi Flegrei vents of Fondi di Baia, Bacoli and Nisida were dated using 40Ar/39Ar geochronology. These vents, together with several other young edifices, occur roughly along the inner border of the Campi Flegrei caldera, suggesting that the volcanic conduits are controlled by caldera-bounding faults. Plateau ages of ∼9.6 ka (Fondi di Baia), ∼8.6 ka (Bacoli) and ∼3.9 ka (Nisida) indicate eruptive activity during intervals previously interpreted as quiescent. A critical revision, involving calendar age correction of literature 14C data and available 40Ar/39Ar age data, is presented. A new reference chronostratigraphic framework for Holocene Phlegrean activity, which significantly differs from the previously adopted ones, is proposed. This has important implications for understanding the Campi Flegrei eruptive history and, ultimately, for the evaluation of related volcanic risk and hazard, for which the inferred history of its recent activity is generally taken into account.

    The Breccia Museo Member is a pyroclastic deposit produced during an eruptive event that occurred in the southwestern sector of Campi Flegrei about 20,000 years ago. Two depositional units divided by a co-ignimbrite ash-fall deposit have been recognized. Facies variations in the deposits resulted from the interaction between the flow and paleomorphology, from the relative abundance of the lithic and juvenile components supplied by the source, and from the variations of the flow regime. The Lower Depositional Unit is a pyroclastic flow deposit characterized by a thick, coarse valley facies laterally grading into a thin, layered and fine-grained overbank facies. These different facies are due to the interaction between a density-stratified flow and topography. The more basal, high-concentration part of the flow was deposited along the axis of the paleovalleys (valley facies), whereas the upper, low-concentration part was deposited on the slopes (overbank facies). Vertical variations of the structures observed in the deposits of the Lower Depositional Unit resulted from flow unsteadiness during emplacement and, hence, on the variations of the suspended load fallout from the low-concentration upper part of the flow to the high-concentration boundary layer. The Upper Depositional Unit, made up of the Breccia, Spatter and Upper Pumice Flow Units, consists of horizons of lithic breccias and coarse welded spatter which thicken into the valleys. They are closely related to a gas-pipe-rich ash and pumice flow deposit. The strongly fines-poor character of the breccias and spatter beds is due to a very rapid segregation of the dense and coarse clasts and to the high rates of gas ascent through the hindered-settling zone in the basal part of the flow. After deposition of the majority of the dense and coarse material, the subsequent high-density depositional system came to rest immediately, thus yielding a pyroclastic flow deposit that is closely associated with the breccia.

    The western coastal sector of Campania region (southern Italy) is characterised by the presence of the active volcano-tectonic area of Campi Flegrei. This area represents a very particular and interesting case-study for a probabilistic seismic hazard analysis (PSHA). The principal seismic source, related with the caldera, is not clearly constrained in the on-shore and off-shore areas. The well-known and monitored phenomenon of bradyseism affecting a large portion of case-study area is not modelled in the standard PSHA approach. From the environmental point of view the presence of very high exposed values in terms of population, buildings, infrastructures and palaces of high archaeological, natural and artistic value, makes this area a strategic natural laboratory to develop new methodologies. Moreover the geomorphological and geo-volcanological features lead to a heterogeneous coastline, made up by both beach and tuff cliffs, rapidly evolving for erosion and landslide (i.e. mainly rock fall and rock slide) phenomena that represent an additional hazard aspect. In the Campi Flegrei the possible occurrence of a moderate/large seismic event represents a serious threat for the inhabitants, for the infrastructures as well as for the environment. In the framework of Italian MON.I.C.A project (sinfrastructural coastlines monitoring) an innovative and dedicated probabilistic methodology has been applied to identify the areas with higher tendency of landslide occurrence due to the seismic effect. Resident population reported the occurrence of some small rock falls along tuff quarry slopes during the main shocks of the 1982-84 bradyseismic events. The PSHA methodology, introduced by Cornell (1968), combines the contributions to the hazard from all potential sources of earthquakes and the average activity rates associated to each seismogenic zone considered. The result of the PSHA is represented by the spatial distribution of a ground-motion (GM) parameter A, such as Peak

    This study provides innovative mathematical models for assessing the eruption probability and associated volcanic hazards, and applies them to the Campi Flegrei caldera in Italy. Throughout the book, significant attention is devoted to quantifying the sources of uncertainty affecting the forecast estimates. The Campi Flegrei caldera is certainly one of the world’s highest-risk volcanoes, with more than 70 eruptions over the last 15,000 years, prevalently explosive ones of varying magnitude, intensity and vent location. In the second half of the twentieth century the volcano apparently once again entered a phase of unrest that continues to the present. Hundreds of thousands of people live inside the caldera and over a million more in the nearby city of Naples, making a future eruption of Campi Flegrei an event with potentially catastrophic consequences at the national and European levels.

    To date, the origin of the Campi Flegrei caldera is still under debate and may be related to (1) a single caldera collapse associated with the Neapolitan Yellow Tuff (NYT) eruption, (2) two subsequent caldera collapses associated with the NYT and the preceding Campanian Ignimbrite (CI) eruptions forming a nested-caldera complex, or (3) not related to a caldera collapse after all. Here, we study the submerged portion of the caldera, which has favored a marine depositional setting and, thus, represents an ideal location for the reconstruction of its formation history, utilizing multichannel seismic data. Volcanic deposits and edifices were seismically distinguished from sedimentary successions, and the stratigraphy could be refined and extended back to the Campanian Ignimbrite eruption at 39 ka. High-resolution multichannel reflection seismic data revealed the existence of a nested-caldera complex formed during the CI eruption at 39 ka and the more recent NYT eruption at 15 ka. A ring-fault bounding an inner caldera collapse structure was clearly imaged. It appears that this inner ring-fault was initially activated during the CI caldera collapse and later reactivated during the NYT caldera collapse with different amounts of subsidence. The NYT caldera probably formed during an asymmetrical collapse with a maximum subsidence of 75 m in the offshore portion. The vertical displacement related to the CI caldera collapse may be significantly larger. The submerged caldera depression accommodates post-eruption sediments. Within this high-resolution archive, two major unconformities developed at 8.6 ka and 5 ka, when resurgence-related uplift exceeded the rate of sea-level rise concurrent with the emersion of the La Starza terrace. A previously unknown post-collapse submarine volcanic mound located between Nisida Island and Nisida Bank probably formed between 4.8 and 3.7 ka. Also, the Penta Palummo Bank appears to be constructed of at least two monogenetic volcanic edifices

    The active volcanic area of Campi Flegrei caldera has been the site of many geothermal investigations, since the early XX century. This caldera is characterised by high heat flow, with maximum value > 150 mWm-2, geothermal gradients larger than 200°Ckm-1 and diffuse magmatic gases discharge at the surface. These features encouraged an extensive campaign for geothermal investigation, started in 1939, with many drillings performed at Campanian volcanoes (Campi Flegrei and Ischia) and later at Vesuvius. Several wells aimed to the exploitation of high enthalpy geothermal energy, were drilled in the Campi Flegrei caldera, down to a maximum depth of ~3 km involving mainly two sites (Mofete and S.Vito geothermal fields) located in western and northern sector of caldera respectively. The most interesting site for geothermal exploitation was the Mofete zone, where a number of 4 productive wells were drilled and tested to produce electrical power. Based on data inferred from the productive tests it was established a potential electrical extractable power from Mofete field of at least 10MWe. More recently an empirical evaluation of the whole geothermal potential of the caldera provides a value of more than 1 GWe. The results of AGIP-ENEL exploration at Campi Flegrei highlighted the feasibility of geothermal exploitation. Here, we show for the first time the results of numerical simulations (TOUGH2 code ®) of fluids extraction and reinjection from the Mofete geothermal field, in order to produce at least 5MWe from zero emission power plant (Organic Rankine Cycle type). The simulation is aimed to understand the perturbation of the geothermal reservoir in terms of temperature, pressure change, and possible related seismicity, after different simulated time of exploitation. The modeling is mainly constrained by the data derived from geothermal exploration and productive tests performed since 1979 by AGIP-ENEL Companies.

    Full Text Available The Campi Flegrei caldera is an active volcanic system associated to a high volcanic risk, and represents a well known and peculiar example of ground deformations (bradyseism, characterized by intense uplift periods, followed by subsidence phases with some episodic superimposed mini-uplifts. Ground deformation is an important volcanic precursor, and, its continuous monitoring, is one of the main tool for short time forecast of eruptive activity. This paper provides an overview of the continuous GPS monitoring of the Campi Flegrei caldera from January 2000 to July 2013, including network operations, data recording and processing, and data products. In this period the GPS time series allowed continuous and accurate tracking of ground deformation of the area. Seven main uplift episodes were detected, and during each uplift period, the recurrent horizontal displacement pattern, radial from the “caldera center”, suggests no significant change in deformation source geometry and location occurs. The complete archive of GPS time series at Campi Flegrei area is reported in the Supplementary materials. These data can be usefull for the scientific community in improving the research on Campi Flegrei caldera dynamic and hazard assessment.

    In the communication chain between scientists and decision makers (end users), scientific outputs, as maps, are a fundamental source of information on hazards zoning and the related at risk areas definition. Anyway the relationship between volcanic phenomena, their probability and potential impact can be complex and the geospatial information not easily decoded or understood by not experts even if decision makers. Focusing on volcanic hazard the goal of MED SUV WP6 Task 3 is to improve the communication efficacy of scientific outputs, to contribute in filling the gap between scientists and decision-makers. Campi Flegrei caldera, in Neapolitan area has been chosen as the pilot research area where to apply an evaluation/validation procedure to provide a robust evaluation of the volcanic maps and its validation resulting from end users response. The selected sample involved are decision makers and officials from Campanian Region Civil Protection and municipalities included in Campi Flegrei RED ZONE, the area exposed to risk from to pyroclastic currents hazard. Semi-structured interviews, with a sample of decision makers and civil protection officials have been conducted to acquire both quantitative and qualitative data. The tested maps have been: the official Campi Flegrei Caldera RED ZONE map, three maps produced by overlapping the Red Zone limit on Orthophoto, DTM and Contour map, as well as other maps included a probabilistic one, showing volcanological data used to border the Red Zone. The outcomes' analysis have assessed level of respondents' understanding of content as displayed, and their needs in representing the complex information embedded in volcanic hazard. The final output has been the development of a leaflet as "guidelines" that can support decision makers and officials in understanding volcanic hazard and risk maps, and also in using them as a communication tool in information program for the population at risk.

  3. Correlation of deposits and vent locations of the proximal Campanian Ignimbrite deposits, Campi Flegrei, Italy, based on natural remanent magnetization and anisotropy of magnetic susceptibility characteristics

    Correlation of the distal deposits of the Campanian Ignimbrite with their proximal equivalents in the Campi Flegrei caldera is complicated by a lack of medial exposures, complex and limited proximal stratigraphic sections, and large lateral facies changes. Paleomagnetic data from 10 sites in and near the Campi Flegrei yield natural remanent magnetizations (NRM) that are statistically indistinguishable from the distal Campanian Ignimbrite. In addition, their virtual geomagnetic pole (VGP) yields a possible correlation with Lac du Bouchet, France, secular variation data that indicate an age of approximately 32,850 14C years. The secular variation curve at this age was only briefly at this VGP, and did not return to it for >10,000 years, so the paleomagnetic correlation of proximal and distal deposits is unique and robust. The date is consistent with 14C dates from the Campanian Ignimbrite, but younger than 39Ar/ 40Ar dates for the same rocks. This suggests that a better correction factor for cosmic flux for this time period is needed to calibrate older 14C dates. Anisotropy of magnetic susceptibility (AMS) data show that the proximal deposits have an oblate (disk-shaped), poorly lineated magnetic fabric. The distal deposits are much better lineated. The difference may be due to chaotic depositional currents in the proximal areas, in which particles were not well aligned. With greater distance of travel, and loss of energy, particles within the flow became aligned and developed stronger AMS lineations. Early eruptions of the Piperno Tuff were from a central vent north of Pozzuoli, whereas later tuffs that underlie the Breccia Museo may have been emplaced by flows associated with ring vents located on the northern and southern caldera margins.

    The Breccia Museo Member (BMM) was formed by an explosive eruption that occurred in the SW sector of Campi Flegrei about 20 ka ago. The eruptive sequence consists of the Lower Pumice Flow Unit and the overlying Upper Pumice Flow Unit with its associated lithic Breccia Unit. Interlayered with the Breccia Unit is a welded deposit that mainly consists of spatter clasts (Spatter Unit). The products of this eruption range in composition from trachytic to trachyphonolitic with K 2O decreasing from 9.5 to 7 wt.%; Na 2O correspondingly increases from 2.6 to 7.2 wt.% with increasing differentiation (Nb from 23 to 122 ppm). The phenocrysts are mostly sanidine (Or 88-63) with subordinate plagioclase (An 33-27), clinopyroxene (Ca 47Mg 44Fe 9 to Ca 46Mg 35Fe 19), biotite, titanomagnetite, and apatite. The observed major- and trace-element variations are fully consistent with about 80% fractional crystallization of a sanidine-dominated assemblage starting from the least differentiated trachytes. The compositions of the erupted products are compatible with the progressive tapping of a shallow magma chamber that was thermally and chemically zoned. The incompatible trace elements indicate a slightly different magma composition with respect to trachytes of the Campi Flegrei mainland. The geochemical stratigraphy suggests that after an early eruptive phase during which the upper, most differentiated level of the magma chamber was tapped, the sudden collapse of the roof of the reservoir triggered drainage of the remaining magma, which ranged in composition from trachyte to trachyphonolite, and formed the Breccia Unit and the Upper Pumice Flow Unit. The strongly differentiated trachyphonolite composition of the spatter clasts also suggests that they likely originated from the uppermost part of the reservoir soon after the eruption of Lower Pumice Flow Unit and the collapse of the chamber roof. This is in agreement with the eruptive model proposed by Perrotta and Scarpati (1994).

    The 501 m deep hole of the Campi Flegrei Deep Drilling Project, located west of the Naples metropolitan area and inside the Campi Flegrei caldera, gives new insight to reconstruct the volcano-tectonic evolution of this highly populated volcano. It is one of the highest risk volcanic areas in the world, but its tectonic structure, eruptive history, and size of the largest eruptions are intensely debated in the literature. New stratigraphic and 40Ar/39Ar geochronological dating allow us to determine, for the first time, the age of intracaldera deposits belonging to the two highest magnitude caldera-forming eruptions (i.e., Campanian Ignimbrite, CI, 39 ka, and Neapolitan Yellow Tuff, NYT, 14.9 ka) and to estimate the amount of collapse. Tuffs from 439 m of depth yield the first 40Ar/39Ar age of ca. 39 ka within the caldera, consistent with the CI. Volcanic rocks from the NYT were, moreover, detected between 250 and 160 m. Our findings highlight: (i) a reduction of the area affected by caldera collapse, which appears to not include the city of Naples; (ii) a small volume of the infilling caldera deposits, particularly for the CI, and (iii) the need for reassessment of the collapse amounts and mechanisms related to larger eruptions. Our results also imply a revaluation of volcanic risk for the eastern caldera area, including the city of Naples. The results of this study point out that large calderas are characterized by complex collapse mechanisms and dynamics, whose understanding needs more robust constraints, which can be obtained from scientific drilling.

    The Campi Flegrei (CF) caldera is located in a densely populated area close to Naples (Southern Italy). It is renowned as a site of continual slow vertical movements. After the last eruption in 1538, the caldera generally subsided until 1969 when minor uplift occurred. In the early 1970s this uplift became significant (~1.5 m max). A further large uplift episode occurred from 1982 to 1984 (~1.8 m max), and subsequently smaller uplift episodes have occurred since then. Amoruso et al. (2014a,b) have recently shown that the CF surface deformation field from 1980 to 2013 can be decomposed into two stationary parts. Large-scale deformation can be explained by a quasi-horizontal source, oriented NW to SE and mathematically represented by a pressurized finite triaxial ellipsoid (PTE) ~4 km deep, possibly related to the injection of magma and/or magmatic fluids from a deeper magma chamber into a sill, or pressurization of interconnected (micro)cavities. Residual deformation not accounted for by PTE is confined to the Solfatara fumarolic area and can be mathematically explained by a small (point) pressurized oblate spheroid (PS) ~2 km below the Solfatara fumarolic field, that has been equated with a poroelastic response of the substratum to pore pressure increases near the injection point of hot magmatic fluids into the hydrothermal system. A satisfying feature of this double source model is that the geometric source parameters of each are constant over the period 1980-2013 with the exception of volume changes (potencies). Several papers have ascribed CF deformation to the injection of magmatic fluids at the base of the hydrothermal system. All models predict complex spatial and temporal evolution of the deformation pattern and consequently contrast with the observed deformation pattern stationarity. Also recently proposed dynamic models of sill intrusion in a shallow volcanic environment do not satisfy the observed CF deformation pattern stationarity. We have developed an

    In this poster we present the framework of the Project "UNREST" and the preliminary results obtained in the first 18 months of activity. The Campi Flegrei resurgent caldera, where several hundred thousands people live, have been characterized during last decades by several bradiseismic crises which determined the partial evacuation of the population, as for the crises in 1969-72 and 1982-84. Recent studies have revealed a process of unrest which continues since the fifties, and which presents characteristics similar to the several centuries-decades long unrest period which led to the last eruption in AD 1538. In the frame of last INGV-DPC Agreement a method has been developed, which allows accounting of any information and associated uncertainty coming from historical, field, and modelling studies, and from the monitoring network, providing a probability on the state of the volcano and on the occurrence of an eruption. In the present project this method is explored and developed, particularly through the experimentation of methods for the definition of reference parameters and thresholds, and of criteria and procedures to make it an operational tool useful for volcano surveillance and crisis management. The research in the project include the following points: a) Definition of the reference database for the validation of models of pre-eruptive dynamics. The database will include geologic, geophysic, geochemical, hydrological and hystorical data. b) Quantitative analysis of measured signals, and formulation of hypotheses on source mechanisms. c) Definition of a general conceptual model for the magma-rocks-geothermal system at Campi Flegrei. d) Physico-mathematical modelling and numerical simulation of the magmatic and geothermal process dynamics, and of the space-time relationships between such dynamics and the geophysical and geochemical signals measured at the surface. e) Definition of the critical parameters for the definition of the different unrest phases, and

    We present a new methodology using bottom pressure recorder (BPR) measurements in conjunction with sea level, water column, and barometric data to assess the long-term vertical seafloor deformation to a few centimeters accuracy in shallow water environments. The method helps to remove the apparent vertical displacement on the order of tens of centimeters caused by the BPR instrumental drift and by seawater density variations. We have applied the method to the data acquired in 2011 by a BPR deployed at 96 m depth in the marine sector of the Campi Flegrei Caldera, during a seafloor uplift episode of a few centimeters amplitude, lasted for several months. The method detected a vertical uplift of the caldera of 2.5 ± 1.3 cm achieving an unprecedented level of precision in the measurement of the submarine vertical deformation in shallow water. The estimated vertical deformation at the BPR also compares favorably with data acquired by a land-based GPS station located at the same distance from the maximum of the modeled deformation field. While BPR measurements are commonly performed in deep waters, where the oceanic noise is relatively low, and in areas with rapid, large-amplitude vertical ground displacement, the proposed method extends the capability of estimating vertical uplifts from BPR time series to shallow waters and to slow deformation processes.

    Full Text Available A temperature profile 2400 m along the off-shore active caldera of Campi Flegrei (Gulf of Pozzuoli was obtained by the installation of a permanent fiber-optic monitoring system within the framework of the Innovative Monitoring for Coastal and Marine Environment (MON.I.C.A project. The system consists of a submerged, reinforced, multi-fiber cable containing six single-mode telecom grade optical fibers that, exploiting the stimulated Brillouin scattering, provide distributed temperature sensing (DTS with 1 m of spatial resolution. The obtained data show that the offshore caldera, at least along the monitored profile, has many points of heat discharge associated with fluid emission. A loose association between the temperature profile and the main structural features of the offshore caldera was also evidenced by comparing DTS data with a high-resolution reflection seismic survey. This represents an important advancement in the monitoring of this high-risk volcanic area, since temperature variations are among the precursors of magma migration towards the surface and are also crucial data in the study of caldera dynamics. The adopted system can also be applied to many other calderas which are often partially or largely submerged and hence difficult to monitor.

    The Campi Flegrei which includes part of the city of Naples, is an active volcanic system; its last eruption occurred in 1538 AD. More recently two significant crises occurred between 1969 and 72 and 1982-84 and were accompanied by ground movements (bradyseism) and seismic activity, forcing people of the town of Pozzuoli to be evacuated. Since 1984 development of a volcanic emergency plan has been underway. In 2000 Civil Protection published a risk map which defined the Red Zone, an area highly at risk from pyroclastic flows, which would need to be evacuated before an eruption. The first study to evaluate the volcanic risk perceptions of the people living within the Campi Flegrei area was completed in spring 2006, resulting in the largest sample ever studied on this topic except for one on Vesuvio area residents by Barberi et al. (2008). A 46 item questionnaire was distributed to 2000 of the approximately 300,000 residents of the Campi Flegrei Red Zone, which includes three towns and four neighborhoods within the city of Naples. A total of 1161 questionnaires were returned, for an overall response rate of 58%. Surveys were distributed to junior high and high school students, as well as to adult members of the general population. Results indicated that unlike issues such as crime, traffic, trash, and unemployment, volcanic hazards are not spontaneously mentioned as a major problem facing their community. However, when asked specific questions about volcanic risks, respondents believe that an eruption is likely and could have serious consequences for themselves and their communities and they are quite worried about the threat. Considering the events of 1969-72 and 1982-84, it was not surprising that respondents indicated earthquakes and ground deformations as more serious threats than eruptive phenomena. Of significant importance is that only 17% of the sample knows about the existence of the Emergency Plan, announced in 2001, and 65% said that they have not received

    Near-infrared room temperature tunable diode lasers (TDL) have recently found increased usage in atmospheric chemistry and air monitoring research, but applications in volcanology are still limited to a few examples. Here, we explored the potential of a commercial infrared laser unit (GasFinder 2.0 from Boreal Laser Ltd) for measurement of volcanic CO2 mixing ratios, and ultimately for estimating the volcanic CO2 flux. Our field tests were conducted at Campi Flegrei near Pozzuoli, Southern Italy, where the GasFinder was used during three campaigns in October 2012, January 2013 and May 2013 to repeatedly measure the path-integrated mixing ratios of CO2 along cross sections of the atmospheric plumes of two major fumarolic fields (Solfatara and Pisciarelli). By using a tomographic post-processing routine, we resolved, for each of the two fields, the contour maps of CO2 mixing ratios in the atmosphere, from the integration of which (and after multiplication by the plumes' transport speeds) the CO2 fluxes were finally obtained. We evaluate a total CO2 output from the Campi Flegrei fumaroles of ˜490 Mg/day, in line with independent estimates based on in situ (Multi-GAS) observations. We conclude that TDL technique may enable CO2 flux quantification at other volcanoes worldwide.

    The Breccia Museo, a pyroclastic flow that crops out in the Campi Flegrei volcanic complex (Naples, Italy), contains alkali-syenite (trachyte) nodules with enrichment in Cl and incompatible elements (e.g., U, Zr, Th, and rare-earth elements). Zircon was dated at ≈52 ka, by U-Th isotope systematics using a SHRIMP. Scanning electron microscope and electron microprobe analysis of the constituent phases have documented the mineralogical and textural evolution of the nodules of feldspar and mafic accumulations on the magma chamber margins. Detailed electron microprobe data are given for alkali and plagioclase feldspar, salite to ferrosalite clinopyroxene, pargasite, ferrogargasite, magnesio-hastingsite hornblende amphibole, biotite mica, Cl-rich scapolite, and a member (probable davyne-type) of the cancrinite group. Detailed whole rock, major and minor element data are also presented for selected nodules. A wide variety of common and uncommon accessory minerals were identified such as zircon, baddeleyite, zirconolite, pollucite, sodalite, titanite, monazite, cheralite, apatite, titanomagnetite and its alteration products, scheelite, ferberite, uraninite/thorianite, uranpyrochlore, thorite, pyrite, chalcopyrite, and galena. Scanning electron microscope analysis of opened fluid inclusions identified halite, sylvite, anhydrite, tungstates, carbonates, silicates, sulfides, and phosphates; most are probably daughter minerals. Microthermometric determinations on secondary fluid inclusions hosted by alkali feldspar define a temperature regime dominated by hypersaline aqueous fluids. Fluid-inclusion temperature data and mineral-pair geothermometers for coexisting feldspars and hornblende and plagioclase were used to construct a pressure-temperature scenario for the development and evolution of the nodules. We have compared the environment of porphyry copper formation and the petrogenetic environment constructed for the studied nodules. The suite of ore minerals observed in

    Full Text Available During the 1982–1984 bradyseismic crises in the Campi Flegrei area (Italy, the University of Wisconsin deployed a network of seismological stations to record local earthquakes. In order to analyse the potential of the recorded data in terms of tomographic imaging, a blind test was recently set up and carried out in the framework of a research project. A model representing a hypothetical 3D structure of the area containing the Campi Flegrei caldera was also set up, and a synthetic dataset of time arrivals was in turn computed. The synthetic dataset consists of several thousand P- and S-time arrivals, computed at about fourteen stations. The tomographic inversion was performed by four independent teams using different methods. The teams had no knowledge of either the input velocity model or the earthquake hypocenters used to create the synthetic dataset. The results obtained by the different groups were compared and analysed in light of the true model. This work provides a thorough analysis of the earthquake tomography potential of the dataset recording the seismic activity at Campi Flegrei in the 1982–1984 period. It shows that all the tested earthquake tomography methods provide reliable low-resolution images of the background velocity field of the Campi Flegrei area, but with some differences. However, none of them succeeds in detecting the hypothetical structure details (i.e. with a size smaller than about 1.5–2 km, such as a magmatic chamber 4 km deep and especially the smaller, isolated bodies, which represent possible magmatic chimneys and intrusions.

    Barium diffusion chronometry applied to sanidine phenocrysts from the trachytic Agnano-Monte Spina eruption (˜4.7 ka) constrains the time between reactivation and eruption of magma batches in the Campi Flegrei caldera. Backscattered electron imaging and quantitative electron microprobe measurements on 50 sanidine phenocrysts from representative pumice samples document core-to-rim compositional zoning. We focus on compositional breaks near the crystal rims that record magma mixing processes just prior to eruption. Diffusion times were modeled at a magmatic temperature of 930 °C using profiles based on quantitative BaO point analyses, X-ray scans, and grayscale swath profiles, yielding times ≤60 years between mixing and eruption. Such short timescales are consistent with volcanological and geochronological data that indicate that at least six eruptions occurred in the Agnano-San Vito area during few centuries before the Agnano-Monte Spina eruption. Thus, the short diffusion timescales are similar to time intervals between eruptions. Therefore, the rejuvenation time of magma residing in a shallow reservoir after influx of a new magma batch that triggered the eruption, and thus pre-eruption warning times, may be as short as years to a few decades at Campi Flegrei caldera.

    The Campi Flegrei volcanic field (Italy) poses very high risk to the highly urbanized Neapolitan area. Eruptive history was dominated by explosive activity producing pyroclastic currents (PDCs; (Proclastic Density Currents) ranging in scale from localized base surges to regional flows. Here we apply probabilistic numerical simulation approaches to produce PDC hazard maps, based on a comprehensive spectrum of flow properties and vent locations. These maps and provide all probable Volcanic Explosivity Index (VEI) scenarios from different source vents in the caldera, relevant for risk management planning. For each VEI scenario, we report the conditional probability for PDCs (i.e., the probability for a given area to be affected by the passage of PDCs) and related dynamic pressure. Model results indicate that PDCs from VEI<4 events would be confined within the Campi Flegrei caldera, PDC propagation being impeded by the northern and eastern caldera walls. Conversely, PDCs from VEI 4-5 events could invade a wide...

    Near-infrared room-temperature Tunable Diode Lasers (TDL) have recently found increased usage in atmospheric chemistry and air monitoring research, but applications in Volcanology are still limited to a few examples. Here, we explored the potentiality of a commercial infrared laser unit (GasFinder 2.0 from Boreal Laser Ltd) to measurement of volcanic CO2 flux emissions. Our field tests were conducted at Campi Flegrei (near Pozzuoli, Southern Italy), where the GasFinder was used (during three campaigns in October 2012, January 2013 and May 2013) to repeatedly measure the path-integrated concentrations of CO2 along cross-sections of the atmospheric plumes of the two main fumarolic fields in the area (Solfatara and Pisciarelli). By using ad-hoc designed field-set-up and a tomographic post-processing routine, we resolved, for each of the 2 manifestations, the contour maps of CO2 concentrations in their atmospheric plumes, from the integration of which (and after multiplication by the plumes' transport speeds) the CO2 fluxes were finally obtained [1]. The so-calculated fluxes average of 490 tons/day, which agrees well with independent evaluations of Aiuppa et al. (2013) [2] (460 tons/day on average), and support a significant contribution of fumaroles to the total CO2 budget. The cumulative (fumarole [this study] +soil [2]) CO2 output from Campi Flegrei is finally evaluated at 1600 tons/day. The application of lasers to volcanic gas studies is still an emerging (though intriguing) research field, and requires more testing and validation experiments. We conclude that TDL technique may valuably assist CO2 flux quantification at a number of volcanic targets worldwide. [1] Pedone M. et al.

  17. Gravity field at unrest caldera: an application to Campi Flegrei area

    Campi Flegrei is a well known volcanic caldera which is characterized by a slow sequence of uplifts and downlifts (bradyseism) superimposed to a sporadic but remarkable explosive activity. Last eruption occurred in 1538, while the most recent uplift episodes (1970-72 and 1982-84) produced about 3 m of cumulative displacement at the town of Pozzuoli. This behavior and the proximity of the densely urbanized town of Naples increases the volcanic hazard of the area. The knowledge of the structural characteristics of the caldera is important to better understand and interpret measured data as well as the past volcanic history. In this frame, gravity data inversion can provide useful information. We collected and inverted about 1500 gravity data covering Campi Flegrei caldera and Ischia island, which is the other main volcanic center of the area, and was characterized in the past by several explosive eruptions (the last one in 1301), and presently by hydrothermal activity. The 3D inversion method was developed by us to deal with scattered data and the presence of topography, and is based on Thichonov regularization theory. As to Campi Flegrei caldera, its shape and bordering structure is clearly singled out in agreement with seismic tomography results. Less marked borders are also present at shallow depth on the NE part of the area. As to Ischia island, our results show the presence of a central high density block and the border of a caldera roughly coinciding with the coastline of the island.

  18. A temporal record of pre-eruptive magmatic volatile contents at Campi Flegrei: Insights from texturally-constrained apatite analyses

    Apatite is capable of incorporating all major magmatic volatile species (H2O, CO2, S, Cl and F) into its crystal structure. Analysis of apatite volatile contents can be related to parental magma compositions through the application of pressure and temperature-dependent exchange reactions (Piccoli and Candela, 1994). Once included within phenocrysts, apatite inclusions are isolated from the melt and preserve a temporal record of magmatic volatile contents in the build-up to eruption. In this work, we measured the volatile compositions of apatite inclusions, apatite microphenocrysts and pyroxene-hosted melt inclusions from the Astroni 1 eruption of Campi Flegrei, Italy (Stock et al. 2016). These data are coupled with magmatic differentiation models (Gualda et al., 2012), experimental volatile solubility data (Webster et al., 2014) and thermodynamic models of apatite compositional variations (Piccoli and Candela, 1994) to decipher pre-eruptive magmatic processes. We find that apatite halogen/OH ratios decreased through magmatic differentiation, while melt inclusion F and Cl concentrations increased. Melt inclusion H2O contents are constant at ~2.5 wt%. These data are best explained by volatile-undersaturated differentiation over most of the crystallisation history of the Astroni 1 melt, with melt inclusion H2O contents reset at shallow levels during ascent. Given the high diffusivity of volatiles in apatite (Brenan, 1993), the preservation of volatile-undersaturated melt compositions in microphenocrysts suggests that saturation was only achieved 10 - 103 days before eruption. We suggest that late-stage transition into a volatile-saturated state caused an increase in magma chamber overpressure, which ultimately triggered the Astroni 1 eruption. This has major implications for monitoring of Campi Flegrei and other similar volcanic systems. Piccoli and Candela, 1994. Am. J. of Sc., 294, 92-135. Stock et al., 2016, Nat. Geosci.

    The Solfatara crater is a highly active hydrothermal site located in the central part of the Campi Flegrei Caldera (south-central Italy). Campi Flegrei is one of most active calderas in the world, characterized by intense unrest episodes involving massive ground deformation, high seismicity and continuous gas emissions from the Solfatara crater. These episodes are thought to be driven by the complex interaction between a deep magmatic source and a shallow hydrothermal system [Orsi et al., 1999]. The most recent unrest episode started in 2006, exhibiting an increase in the degassing activity, especially in the Pisciarelli field (SE of Solfatara crater). In such an active magmato-hydrothermal system steam-driven explosive eruptions (phreatic or hydrothermal) are a likely potential hazard - one that is difficult to predict in terms of timing and magnitude. Here we present an experimental approach based on a rapid decompression experiments to investigate the different scenarios likely for steam explosions in the Solfatara area. The experimental setup produces fragmentation precipitated by the release of Argon gas overpressure and assisted by water-to-steam flashing within the connected pore space of the tested samples. We have investigated varying P-T conditions and varying gas-to-liquid ratios. The experimental conditions used in this case study mimic those of a mixing zone present at the base of the hydrothermal system below Solfatara at a depth between 1000 and 1500 m (15-25 MPa) and temperatures from 270°C to 300°C [Caliro et al., 2007]. Neapolitan Yellow Tuff is used as sample material for the study as it is the stratigraphic unit expected at this depth in this region [Orsi et al. 1996]. Sensors monitor temperature and pressure evolution during the experiments, enabling the determination of the speed of fragmentation. A high-speed camera (10000 fps) is used to measure the ejection velocities of the gas-particle mixtures. The fragments generated are recovered and

    Timescales governing the development of crustal magma reservoirs are a key for understanding magmatic processes such as ascent, storage and mixing event. An estimate of these timescales can provide important constraints for volcanic hazard assessment of active volcanoes. We studied the Agnano-Monte Spina eruption (A-MS; 4.7 ka; VEI = 4; 0.85 km3 D.R.E. of magma erupted) of the Campi Flegrei caldera, one of the most dangerous volcanic areas on Earth. The A-MS eruption has been fed by magmas varying from more to less evolved trachyte whose variable 87Sr/86Sr and trace elements features suggest magma mixing between two end-members. Ba zonation profiles of alkali feldspar phenocrysts have been determined through combined energy-dispersive and wavelength-dispersive electron microprobe analyses (EDS-WDS-EMPA). We focused on distinct compositional breaks near the rim of the crystals that likely represent the last mixing event prior to eruption. We always chose the steepest gradients close to the crystal rims, taking into account that any effects related to cutting angles or crystal orientation should give longer apparent diffusion times. Two different approaches were undertaken: (1) a quantitative Ba compositional profiles were measured by point analyses along a short transect crossing growth discontinuities and (2) grey-scale profiles were taken parallel to the acquired point profiles. Assuming that Ba dominates the backscattered electron intensities in sanidines, greyscale gradients can be used as a diffusive tracer. BSE images were processed using the ImageJ® software, in order to extract a numerical greyscale profile. In both cases, each profile was interpolated through a non-linear Boltzmann fit curve with the Mathematica® software. A few traverses done at angles smaller than 90° to the compositional boundary interface were corrected by multiplying the distance values by the sinus of the traverse angle relative to the vertical on the interface.

    This work is devoted to the analysis of seismic signals continuously recorded at Campi Flegrei Caldera (Italy) during the entire year 2006. The radiation pattern associated with the Long-Period energy release is investigated. We adopt an innovative Independent Component Analysis algorithm for convolutive seismic series adapted and improved to give automatic procedures for detecting seismic events often buried in the high-level ambient noise. The extracted waveforms characterized by an improved signal-to-noise ratio allows the recognition of Long-Period precursors, evidencing that the seismic activity accompanying the mini-uplift crisis (in 2006), which climaxed in the three days from 26-28 October, had already started at the beginning of the month of October and lasted until mid of November. Hence, a more complete seismic catalog is then provided which can be used to properly quantify the seismic energy release. To better ground our results, we first check the robustness of the method by comparing it with other blind source separation methods based on higher order statistics; secondly, we reconstruct the radiation patterns of the extracted Long-Period events in order to link the individuated signals directly to the sources. We take advantage from Convolutive Independent Component Analysis that provides basic signals along the three directions of motion so that a direct polarization analysis can be performed with no other filtering procedures. We show that the extracted signals are mainly composed of P waves with radial polarization pointing to the seismic source of the main LP swarm, i.e. a small area in the Solfatara, also in the case of the small-events, that both precede and follow the main activity. From a dynamical point of view, they can be described by two degrees of freedom, indicating a low-level of complexity associated with the vibrations from a superficial hydrothermal system. Our results allow us to move towards a full description of the complexity of

    The Campi Flegrei (i.e. "burning plains") are located on the eastern Tyrrhenian margin, an area characterized by active tectonics and volcanism since the Pleistocene. It is a densely urbanized coastal zone, including the bay of Pozzuoli, Procida and Ischia islands, where documented human activities have been developing for more than two thousand years. In the Pozzuoli area two major periods of eruptive volcanic activity occurred from 10.0 to 8.0 ky B.P and 4.5 to 3.7 ky B.P. These periods were followed by the September 1538 Monte Nuovo eruption. Numerous monogenic volcanoes formed close to the shoreline and volcanic debris interpreted as submarine counterpart of subaerial flow and surge, has been detected offshore. The most recent volcanic activity on Ischia island starts around 10.0 ky B.P. to which associates several eruptive centres mostly located in the western sector. The last eruption dates back to Arso flow in 1302. Nevertheless the landscape of Ischia is dominated by Mount Epomeo in the central part of the island, which is the highest peak (788 m). It is a volcano-tectonic structure that raised above sea level between 33 and 28 ka BP, due to the intrusion of magma at shallow depth. In the Campi Flegrei, magma-related activity is testified by extensive hydrothermalism, and recent episodes (1883 on Ischia, and 1970-71 and 1982-84 on Pozzuoli coast) of shallow seismicity and ground deformation, exceeding rates of 100 cm/year in the years 1983-1984. Volcanic and volcano-tectonic activity mainly associate with inferred resurgent calderas whose uplift have caused mass wasting phenomena, faulting and erosional activity both on land and at sea. Major geohazard features resulting from marine geophysical and sedimentological investigations include (1) extensive landslide deposits and associated hummocky topographies off Ischia volcanic island, (2) seafloor instabilities in the form of creep/slump, channelled sediment flow and deep sedimentary fan, (3) superficial

    The emission of Hg and H2S from natural and anthropogenic sources may have a great environmental impact in urban areas as well as in the surroundings of active and passive degassing volcanoes. Mercury is present in the atmosphere mainly in its elemental form (Hg0~98 %), which has a relatively high volatility, low solubility and chemical inertness. Hydrogen sulfide, one of the most abundant gas species in volcanic fluids, is highly poisoning and corrosive. In this study, an innovative real-time method for the measurements of Hg0 and H2S concentrations in air was carried out at La Solfatara Crater, a hydrothermally altered tuff-cone nested in the town of Pozzuoli (Southern Italy), and at Mt. Amiata volcano (Central Italy), where a world-class Hg mining district abandoned in the seventies and a presently-exploited geothermal field for the production of electrical energy occur. The main aims were (i) to test this new methodological approach and (ii) to investigate Hg0 and H2S concentrations and the chemical-physical parameters regulating their spatial distribution in polluted areas. A portable Zeeman atomic absorption spectrometer with high frequency modulation of light polarization (Lumex RA-915M) was used in combination with a pulsed fluorescence gas analyzer (Thermo Scientific Model 450i) to measure Hg0 and H2S, respectively. The instruments were synchronized and set at high-frequency acquisition (10 sec and 1 min, respectively). Measurements were carried out along pathways (up to 12 km long) at an average speed of <10 km/h and coupled with GPS data and meteorological parameters. In selected sites, passive samplers were positioned to determine the time-integrated Hg0 and H2S concentrations to be compared with the real-time measurements. The results indicate that this approach is highly efficient and effective in providing reliable and reproducible Hg0 and H2S concentrations and can be used to identify and characterize gas emitters in different environments.

    Uplifts in the Campi Flegrei caldera reach values unsurpassed anywhere in the world (~2 meters). Despite the marked deformation, the release of strain appears delayed. The rock physics analysis of well cores highlights the presence of two horizons, above and below the seismogenic area, underlying a coupled process. The basement is a calc-silicate rock housing hydrothermal decarbonation reactions, which provide lime-rich fluids. The caprock above the seismogenic area has a pozzolanic composition and a fibril-rich matrix that results from lime-pozzolanic reactions. These findings provide evidence for a natural process reflecting that characterizing the cementitious pastes in modern and Roman concrete. The formation of fibrous minerals by intertwining filaments confers shear and tensile strength to the caprock, contributing to its ductility and increased resistance to fracture.

    The caldera of Campi Flegrei is one of the active hydrothermal systems of the Mediterranean region experiencing notable unrest episodes in a densely populated area. During the last crisis of 1982-1984, nearly 40,000 people were evacuated for almost two years from the main town of Pozzuoli, the Roman Puteoli, due to the large uplifts (~2 m over two years) and the persistent seismic activity. The evacuation severely hampered the economy and the social make-up of the community, which included the relocation of schools and commercial shops as well as the harbor being rendered useless for docking. Despite the large uplifts, the release of strain appears delayed. Seismicity begins and reaches a magnitude of 4.0 only upon relatively large uplifts (~ 70-80 cm) contrary to what is generally observed for calderas exhibiting much lower deformation levels. Over and above the specific mechanism causing the unrest and the lack of identification of a shallow magmatic reservoir (concrete. The formation of fibrous minerals by intertwining filaments confers shear and tensile strength to the caprock, contributing to its ductility and increased resistance to fracture. The importance of the findings reported in this study lies not only on the fibrous and compositionally nature of the caprock but also on its possible physicochemical deterioration. Given the P-T-XCO2 conditions regulating the decarbonation reactions, the influx of new fluids into the Campi Flegrei system lowers the temperature of the decarbonation reaction and dilutes the existing CO2, thus triggering additional CO2, methane, and steam to form. As these gases rise toward the surface, the natural cement layer halts them, leading to pore pressure increase and subsequent ground deformations.

    Knowledge of the timescales of magma rising and stagnation, as well as mingling/mixing processes occurring in the shallow plumbing system of an active volcano is crucial for volcanic hazard assessment and risk mitigation. Among few recently developed methodologies, high-precision, high spatial resolution analysis of major-, minor- and trace elements on zoned phenocrysts through electron microprobe techniques represents a powerful tool to provide good estimates of timescales of pre-eruptive magma rising, stagnation and/or mingling/mixing processes. To this purpose, volcanic rock samples of trachytic composition representative of the Agnano-Monte Spina eruption (4.7 ka CAL BP) occurred at the Campi Flegrei caldera (southern Italy) have been selected. The investigation has been carried out in the framework of Project V2 - Precursori di Eruzioni, funded by the Italian Dipartimento per la Protezione Civile - Istituto Nazionale di Geofisica e Vulcanologia. The investigated rock samples are pumice fragments from which double-polished, 100 µm thick thin sections have been prepared for analytical purposes. Back-scattered electrons (BSE) images have been acquired at the scanning electron microscope (SEM), in order to identify the plagioclase phenocrysts suitable to be analyzed successively, selected among those that best display their zoning. After a careful observation of the BSE images, major-, minor- and selected trace element contents have been determined through combined energy-dispersive and wavelength-dispersive system electron microprobe analyses (EDS-WDS-EMPA) on transects crossing the growth zones of the selected phenocrysts. This methodology has allowed reconstructing the diffusion profile of some key-elements through the growth zones of the investigated phenocrysts. Successively, the diffusion profiles have been combined with textural features obtained through BSE images in order to obtain diffusion models aimed at estimating the timescales of crystals

    Solfatara crater is located within the Campi Flegrei caldera to the west of Naples (Italy). It is one of the largest fumarolic manifestations known, and the rocks hosting the hydrothermal system are affected by intense hydrothermal alteration. Alteration can result in changes of degassing behavior, and in the formation of a cap rock thereby increasing the probability of phreatic eruptions. Here, we investigate the effects of alunitic (solfataric) alteration on the mineralogy, the physical properties (porosity, density, permeability) and the mechanical properties (strength) of the rocks involved, as well as its influence on fragmentation and ejection behavior. Our results show that the pristine mineralogy of deposits from the vicinity of the Solfatara cryptodome and from Pisciarelli is almost completely replaced by amorphous silica and alunite. The differences in the degree of alteration among the samples series are reflected in the investigated properties and behavior as well as in the analysis of the experimentally generated particles. Alunitic alteration increases porosity and permeability, whereas it reduces density, elastic wave velocity and strength leading to higher fragmentation and ejection speeds for the sample series examined in this study. Our results also show that alteration results in the generation of a high fraction of fines (particle sizes < 10 μm) during fragmentation, mainly composed of alunite crystals. Due to their potential for inducing chronic disease, dispersion of such material should represent a serious health hazard on a local scale and the evaluation of precautions should be considered.

    Assessment of time and space relationships among magmatism, volcanism, and resurgence of medium-size calderas is a necessary tool to formulate a general model for their dynamics which also permits to forecast their evolution. To define a general hypothesis for the Campi Flegrei caldera, in a persistent state of unrest, the Ischia and Pantelleria medium-size resurgent structures, in variable stages of evolution, have been investigated. In particular some parameters such as the structural and volcanological evolution, with emphasis on resurgence dynamics and coeval volcanism, and the evolution, present state and role of the magmatic system in resurgence, have been defined. For the Campi Flegrei caldera, the data collected during unrest episodes have also been taken into account. This innovative approach adds a time-perspective on how resurgent calderas behave. The proposed general hypothesis will help in long- and short-term volcanic hazards assessment and will support Civil Defence Authorities in elaborating actions devoted to volcanic risk reduction.

    During September 2001, an extended active seismic survey has been performed in the gulfs of Naples and Pozzuoli in the framework of the so called SERAPIS (SEismic Re- flection Acquisition Project for Imaging Structures). The project SERAPIS is aimed at the acquisition in the bays of Naples and Pozzuoli, on land and at the sea bottom (using sea bottom seismographs), of seismic signals emitted by a very dense network of airgun sources. The energization is performed through the syncronized implosion of bubbles produced by a battery of three to twelve, 16 liters airguns, mounted on the oceanographic vessel NADIR, owned by the french company IFREMER, which supported the project at no cost. The experiment has been designed to have 2D-3D acquisition lay-outs and its objective is the high resolution imaging of the main shal- low crustal discontinuities underneath the major neapolitan volcanic complexes. In particular some desired targets are the location and spatial definition of the magmatic feeding system of Campi Flegrei and the morphologic reconstruction of the interface separating the shallow volcano-alluvium sediments and the Mesozoic carbonates, re- cently detected and accurately imaged underneath Mt.Vesuvius volcano. A secondary but not less important objective is the denser re-sampling of areas in the Bay of Naples prospicient to Mt.Vesuvius, which have been investigated during the last marine sur- vey using the same vessel in 1997 (MareVes 97). Sixty, three-component stations have been installed on-land in the areas of Campi Flegrei, Mt.Vesuvius and on the islands of Ischia and Procida. In particular, the Mt.Vesuvius stations have been deployed along a 40 km long, SE-NW profile crossing the Campanian Plain toward the limestone out- crops. 72 sea bottom seismographs (OBS) have been installed in the gulfs of Naples and Pozzuoli by the University of Hamburg, with the logistic support of Geopro smbh and Geolab Italia. The OBS network geometry follows the main

    Combined radiogenic Sr- and stable O-isotopes are a powerful tool to distinguish between (a) contamination of mantle magma sources by fluids and subducted sediment and (b) assimilation of magmas during ascent through the crust. Advance in laser fluorination mass spectrometry permits to measure small samples and single mineral grains. This allows to directly link Sr- and O-isotope measurements practically for the same sample material. Although isotopic heterogeneity remains a problem even at this level, this approach avoids problems of weathering and mineral-melt disequilibria. We analysed mineral separates (feldspar, Fe-cpx, Mg-cpx, magnetite, olivine) from 37 samples covering the stratigraphic sequence of the Campi Flegrei volcanic field: Pre-Campanian Ignimbrite (Pre CI; >39.28 ka), Campanian Ignimbrite (CI; 39.28 ka), Post Campanian Ignimbrite/Pre Neapolitan Yellow Tuff (Post CI/pre NYT; 14.90 ka), Neapolitan Yellow Tuff (NYT; 14.90 ka), and Post-Neapolitan Yellow Tuff (Post NYT; 12.8 ka-1538 A.D.) deposits. Sr isotopic compositions were determined using standard cation-exchange methods on separated hand-picked feldspar, clinopyroxene and olivine phenocrysts (~300mg) and on whole rocks, in case of not enough amount of crystals. By infrared laser fluorination was, instead, measured the oxygen isotopic composition of ~0.3 mg of hand-picked phenocrysts. Recalculating measured mineral O-isotope values to magmatic values to account for mineral-melt 18O/16O-fractionation at various SiO2-contens of the melt should provide a data set that better constrains magma isotope compositions and magma sources. Sr-isotopes span a range from 0.7069 to 0.7082 that exceed the variations in the bulk rock samples (0.7071-0.7081). However, these ranges vary significantly between eruptive periods. For example the Sr-isotope variation in the Neapolitan Yellow Tuff is only between 0.70750 and 0.70754 for minerals and whole rocks. Similarly, recalculated δ18O-melt values show a large

    The Phlegraean Fields (Campi Flegrei) caldera in Italy had one well-documented eruption during the historical period (1538). Another eruption at Solfatara in 1198 is reported by sixteenth and seventeenth-century scholars, and has been commonly regarded as uncertain. In this paper we first discuss the circumstantial evidence and report of this eruption, then discuss the relevance of drawings made in the thirteenth through the fifteenth century illustrating the Solfatara and the primary literary and historical sources describing the site. We infer that the eruption was at most a minor phreatic explosion and we explore the conditions that may have led to the occurrence of this event and the establishment of a small crater pool subsequently used as a thermal bath from the later Middle Ages onward.

    The Campi Flegrei coastal area includes the bay of Pozzuoli, Procida and Ischia islands, characterized by active tectonics and volcanism since the Pleistocene. Numerous monogenic volcanoes occur close to the shoreline and volcanic debris interpreted as submarine counterpart of subaerial flows and surges, have been detected offshore. In the Pozzuoli area the most recent eruptive volcanic activity occurred from 10.0 to 8.0 ky B.P and 4.5 to 3.7 ky B.P. followed by the September 1538 Monte Nuovo eruption. Here magma-related activity is testified by extensive hydrothermalism, and recent episodes (1970-71 and 1982-84 on Pozzuoli coast) of shallow seismicity and ground deformation, exceeding rates of 100 cm/year in the years 1983-1984. The most recent volcanic activity on Ischia island starts around 10.0 ky B.P. to which associates several eruptive centres mostly located in the western sector. The last eruption dates back to Arso flow in 1302. Nevertheless the landscape of Ischia is dominated by Mount Epomeo in the central part of the island, which is the highest peak (788 m). It is a volcano-tectonic structure that raised above sea level between 33 and 28 ka BP, due to the intrusion of magma at shallow depth. Procida island is composed of five monogenic Volcanoes (Vivara, Terra Murata, Pozzo Vecchio, Fiumicello and Solchiaro) that have been active over the last 80 ky producing pyroclastic deposits and a lava dome. A sixth volcanic structure has been reported recently off P.ta Serra by marine investigations and confirmed by airborne magnetic surveys. The emplacement of large amount of volcanoclastic material from volcanic and volcano-tectonic activity in the Campi Flegrei coastal area produced extensive avalanche deposits off Ischia island, seafloor instabilities in the form of creep/slump, channelled sediment flow and deep sedimentary fans, and is largely responsible for aggradation/progradation of the coastal area during the Quaternary. Moreover, numerous volcanic bank

    This paper describes the characteristics of the seismicity in the volcanic Neapolitan area during the year 2000 recorded by the monitoring seismic network of the Osservatorio Vesuviano. In particular, a detailed analysis of the seismicity of Vesiuvius is presented. It is compared the seismic velocity models available for the Vesuvius area locating the earthquakes recorded in the year 2000 and on the basis of the results, it is introduced for routine earthquake location the new velocity model obtained by the seismic tomography experiments (TomoVes) performed in the area. It was also determined the focal mechanisms and analysed the seismicity rate, comparing the results with those obtained for the past years. After the introduction of the new acquisition system at the Osservatorio Vesuviano, a re-calibration of the duration magnitude scale was necessary to avoid biases related to the different instrumental response. Consequently, it was re-calibrated the magnitude relation used for the Vesuvius earthquakes, obtaining a new formula to be used for the earthquakes recorded by the new acquisition system. Finally, it was given a description of the seismic activity in the Campi Flegrei area during the summer of 2000.

    The ongoing unrest at the Campi Flegrei caldera (CFc) in southern Italy is prompting exploration of its poorly studied offshore sector. We report on a multidisciplinary investigation of the Secca delle Fumose (SdF), a submarine relief known since antiquity as the largest degassing structure of the offshore sector of CFc. We combined high-resolution morphobathymetric and seismostratigraphic data with onshore geological information to propose that the present-day SdF morphology and structure developed during the initial stages of the last CFc eruption at Monte Nuovo in AD 1538. We suggest that the SdF relief stands on the eastern uplifted border of a N-S-trending graben-like structure formed during the shallow emplacement of the Monte Nuovo feeding dike. We also infer that the high-angle bordering faults that generated the SdF relief now preferentially allow the ascent of hot brines (with an equilibrium temperature of 179°C), thereby sustaining hydrothermal degassing on the seafloor. Systematic vertical seawater profiling shows that hydrothermal seafloor venting generates a sizeable CO2, pH, and temperature anomaly in the overlying seawater column. Data for the seawater vertical profile can be used to estimate the CO2 and energy (heat) outputs from the SdF area at ˜50 tons/d (˜0.53 kg/s) and ˜80 MW, respectively. In view of the cause-effect relationship with the Monte Nuovo eruption, and the substantial gas and energy outputs, we consider that the SdF hydrothermal system needs to be included in monitoring programs of the ongoing CFc unrest.

  15. The Rock Physics of Fiber-Reinforced Rocks Helps Explain Uplifts at Campi Flegrei Volcano-Hydrothermal System

    The caldera of Campi Flegrei is one of the active volcano-hydrothermal systems of the Mediterranean region experiencing notable unrest episodes in a densely populated area. One peculiar trait characterizes the unrest of this system: the ability of withstanding large uplifts before setting off a swarm of microeartquakes. Therefore, one core question is how the subsurface rocks of Campi Flegrei withstand such a large strain and have high strength. The rock physics analysis of well cores up to 3 km provides evidence for the existence of two horizons, above and below the seismogenic area, underlying a natural, coupled process. The basement is a calc-silicate rock housing hydrothermal decarbonation reactions, which provide lime-rich fluids. The impermeable caprock above the seismogenic area has a pozzolanic composition and a fibril-rich matrix made of intertwining filaments of ettringite and tobemorite, resulting from lime-pozzolanic reactions. These findings provide evidence for a natural process reflecting that of the engineering of the Roman concrete. The formation of fibrous minerals by intertwining filaments confers shear and tensile strength to the caprock, contributing to its ductility and increased resistance to fracture. The importance of these findings lies not only on the fibrous and compositionally nature of the caprock but also on its possible physicochemical deterioration. Given the P-T-XCO2 conditions regulating the decarbonation reactions, possible influx of new brine into the Campi Flegrei system dilutes the existing CO2, thus triggering further decarbonation reaction. This leads to the formation of additional CO2, methane, and steam. As these gases rise toward the surface, they are halted by the natural concrete-like layer, which would lead to pore pressure increase and subsequent ground deformations.

    The Solfatara crater is a highly active hydrothermal site of Campi Flegrei caldera, one of the most dangerous volcanic areas in the world extending to the west of the city of Naples. Currently Campi Flegrei is in a phase of volcanic unrest. Since 2006 an increase of the degassing activity, especially in the Pisciarelli field (SE of Solfatara crater), has been recorded. In addition ground uplift at increasing rates (about 1 cm/month), with a relatively low seismic activity, is observed in the nearby area of Pozzuoli [Osservatorio Vesuviano bulletins]. This ongoing phase of unrest, as most of the last unrest episodes, is thought to be driven by the complex interaction between a deep magmatic source and the shallow hydrothermal system [Orsi et al., 1999]. In a such active hydrothermal and magmatic site steam-driven explosive eruptions (phreatic or hydrothermal) are likely to occur representing a potential hazard especially as they are difficult to predict in terms of timing and magnitude. Here we present an experimental approach based on a rapid decompression experiments to investigate different scenarios likely for steam explosions in the Solfatara area. The setup allows producing fragmentation from a combination of Argon gas overpressure and steam flashing within the connected pore space of the tested samples at varying PT-conditions and varying gas-to-liquid ratios. The experimental conditions used in this case study are mimicking those of a mixing zone present at the base of the hydrothermal system below Solfatara; here at a depth between 1000 and 1500 m (15-25 MPa) the temperature conditions range between 270°C and 375°C [Caliro et al., 2007]. Neapolitan Yellow Tuff is used as sample material for the study as it is the stratigraphic unit of the expected source region for steam explosions [Orsi et al. 1996]. Sensors monitor temperature and pressure evolution during experiments, allowing to determine the speed of fragmentation of the samples. A high-speed camera

    The strong hydrothermal activity exhibited at Campi Flegrei by the Solfatara and Pisciarelli fumaroles points to a significant risk for phreatic eruptions in this densely populated area. Phreatic eruptions, triggered by various processes are hardly predictable in occurrence time and size. Despite their hazard potential, these eruptions, as well as the influence of hydrothermal alteration on their likelihood, magnitude and style, have so far been largely overlooked in experimental volcanology. The physical properties and the mechanical behavior of volcanic rocks are highly dependent on their original magmatic microstructure and on any eventual alteration of those microstructures due to hydrothermal reactions. We have therefore investigated the potential effects of hydrothermal alteration on rock microstructure and, as a consequence, on fragmentation dynamics. Rock samples from the vicinity of the Solfatara fumaroles have been characterized 1) geochemically (X-ray fluorescence, X-ray diffraction), 2) physically (density, porosity, permeability and elastic wave velocity) and 3) mechanically (uniaxial compressive strength, tensile strength). We have investigated the effects of hydrothermal alteration on fragmentation processes using a shock-tube apparatus, operating with Argon gas, water vapor and superheated water at temperatures up to 400°C and maximum pressures of 20 MPa. The three different energy sources within the pores initiating fragmentation, have been investigated: overpressure by 1) Argon gas; or 2) water vapor and due to 3) steam flashing of water. Fragmentation speed, fragmentation efficiency and fragmented particle ejection velocity were measured. Our results indicate, that steam flashing provides the highest energy - resulting in increased particle ejection velocity and higher fragmentation efficiency. Based on our results, we aim to constrain the influence of hydrothermal alteration on the dynamics of phreatic explosions and the effect on the amount of

    We illustrate a quantitative conductive/convective thermal model incorporating a wide range of geophysical, petrological, geological, geochemical and isotopical observations that constrain the thermal evolution and present state of the Campi Flegrei caldera (CFc) magmatic system. The proposed model has been computed on the basis of the current knowledge of: (1) the volcanic and magmatic history of the volcano over the last 44 ka, (2) its underlying crustal structure, and (3) the physical properties of the erupted magmas. 3D numerical simulations of heat conduction and convection within heterogeneous rock/magma materials with evolving heat sources and boundary conditions that simulate magma rise from a deep (≥ 8 km depth) to shallow (2-6 km) reservoirs, magma chamber formation, magma extrusion, caldera collapse, and intra-caldera hydrothermal convection, have been carried out. The evolution of the CFc magmatic system through time has been simulated through different steps related to its changes in terms of depth, location and size of magma reservoirs and their replenishment. The thermal modeling results show that both heat conduction and convection have played an important role in the CFc thermal evolution, although with different timing. The simulated present heat distribution is in agreement with the measured geothermal profiles (Agip, 1987), reproduces the thermal gradient peaks at the CFc margins in correspondence to the anomalies in surface gradients (Corrado et al., 1998), and suggests temperatures of 700 °C at depth of 4 km in the central portion of the caldera, in agreement with the estimated temperature for the brittle-ductile transition (Hill, 1992).

    Alteration of Campi Flegrei pumiceous ash in Roman concrete harbor structures along the central Italian coast produced zeolite and Ca-silicate minerals that have reinforced cementitious fabrics for >2000 years. X-ray microdiffraction experiments and electron microprobe analyses show that diverse alteration paths produced authigenic phillipsite and Al-tobermorite in the pyroclasts, pores, and cementing matrix of mortars in Romacons drill cores from Portus Cosanus, Portus Neronis, and Baianus Sinus. These minerals have cation exchange capabilities for some radionuclides and heavy metal cations and are candidate sorbents for concrete waste encapsulations. Compositions of phillipsite in certain Portus Cosanus and Portus Neronis pumice clasts are similar to those in the Neapolitan Yellow Tuff. Dissolution of this phillipsite and alkali feldspar produced new, authigenic phillipsite with less Si, greater Al and Ca, Al-tobermorite, and poorly-crystalline binder in pumice vesicles. Conversely, alteration of trachytic glass to clay mineral (nontronite) in a Baianus Sinus tuff clast is associated with new, authigenic phillipsite and Al-tobermorite in the tuff and cementing matrix. The Al-tobermorite has lower Al/(Si+Al) and Ca/(Si+Al) compared to Al-tobermorite in relict lime clasts. These more siliceous crystals, similar to those in hydrothermally-altered basalt, have 11.3 Å d-spacing in [001]. Raman spectra show symmetrical bending of Si-O-Si and Si-O-Al linkages, Si-O and Si-Al symmetrical stretching, and possible Q3 Si and Al tetrahedral peaks that suggest cross-linking of silicate chains-an important factor in cation exchange. The authigenic crystals refine pore space, contribute to binding in interfacial zones, and obstruct microcrack propagation. The well-constrained history of temperature variations and seawater immersion could provide further information for understanding alteration in volcanoclastic deposits and predicting regenerative processes in high performance

    The volcanic/geothermal area of Pisciarelli is located within Campi Flegrei caldera .This last is a densely populated area, including the Pozzuoli town and bordering the western side of the Naples city, this causes a high vulnerability and consequently a high volcanic risk. In the recent decades this area has experienced minor ground uplift episodes accompanied by low magnitude seismicity and by strong intensification of degassing activity in particular localized at Pisciarelli area. We present the results of the Terrestrial Laser Scanner (TLS), using a Reigl VZ1000®, analysis of Pisciarelli area performed in June 2013 and the comparison with the data acquired later in March 2014. We apply the TLS technique based on Time of Flight (TOF) method in order to define an accurate 3D digital model for detailed analysis of this area performing numerous scans from different points of view in the area. In this ways was ensured a good coverage of the whole investigated area in order to avoid shaded portion due to the high soil degassing activity. Such fact limits the capacity of laser penetration is caused by wavelength near infrared range. For each survey was obtained a Digital Terrain Model (DTM) from the reconstructed data and both were compared. In particular, we have identified two "critical" areas of interest that will be monitored more frequently. These are: 1) in the lower part of the studied area a major fault line that bounding the Agnano caldera moderately NE-dipping; 2) in the upper part of the study area a zone of depletion with its zone of accumulation. The DTM were georeferenced into the UTM-WGS84 reference frame. The aim of this work is to define a procedure to compare between 3D model applied to monitoring of this area. Also to evaluate of volumetric and morphologic changes and to recognizing unstable masses by comparison of 3D data. For this purpose other TLS surveys will be performed in the upcoming in this active volcanic/geothermal area.

    Full Text Available Volcanic and geothermal aspects both exist in many geologically young areas. In these areas the heat transfer process is of fundamental importance, so that the thermal and fluid-dynamic processes characterizing a viscous fluid in a porous medium are very important to understand the complex dynamics of the these areas. The Campi Flegrei caldera, located west of the city of Naples, within the central-southern sector of the large graben of Campanian plain, is a region where both volcanic and geothermal phenomena are present. The upper part of the geothermal system can be considered roughly as a succession of volcanic porous material (tuff saturated by a mixture formed mainly by water and carbon dioxide. We have implemented a finite elements approach in transient conditions to simulate water flow in a 2-D porous medium to model the changes of temperature in the geothermal system due to magmatic fluid inflow, accounting for a transient phase, not considered in the analytical solutions and fluid compressibility. The thermal model is described by means of conductive/convective equations, in which we propose a thermal source represented by a parabolic shape function to better simulate an increase of temperature in the central part (magma chamber of a box, simulating the Campi Flegrei caldera and using more recent evaluations, from literature, for the medium's parameters (specific heat capacity, density, thermal conductivity, permeability. A best-fit velocity for the permeant is evaluated by comparing the simulated temperatures with those measured in wells drilled by Agip (Italian Oil Agency in the 1980s in the framework of geothermal exploration. A few tens of days are enough to reach the thermal steady state, showing the quick response of the system to heat injection. The increase in the pressure due to the heat transport is then used to compute ground deformation, in particular the vertical displacements characteristics of the Campi Flegrei caldera

    In recent decades, geophysical investigations have detected wide magma reservoirs beneath quiescent calderas. However, the discovery of partially melted horizons inside the crust is not sufficient to put constraints on capability of reservoirs to supply cataclysmic eruptions, which strictly depends on the chemical-physical properties of magmas (composition, viscosity, gas content etc.), and thus on their differentiation histories. In this study, by using geochemical, isotopic and textural records of rocks erupted from the high-risk Campi Flegrei caldera, we show that the alkaline magmas have evolved toward a critical state of explosive behaviour over a time span shorter than the repose time of most volcanic systems and that these magmas have risen rapidly toward the surface. Moreover, similar results on the depth and timescale of magma storage were previously obtained for the neighbouring Somma-Vesuvius volcano. This consistency suggests that there might be a unique long-lived magma pool beneath the whole Neapolitan area.

    Uplifts in the Campi Flegrei caldera reach values unsurpassed anywhere in the world (~2 meters). Despite the marked deformation, the release of strain appears delayed. The rock physics analysis of well cores highlights the presence of two horizons, above and below the seismogenic area, underlying a coupled process. The basement is a calc-silicate rock housing hydrothermal decarbonation reactions, which provide lime-rich fluids. The caprock above the seismogenic area has a pozzolanic composition and a fibril-rich matrix that results from lime-pozzolanic reactions. These findings provide evidence for a natural process reflecting that characterizing the cementitious pastes in modern and Roman concrete. The formation of fibrous minerals by intertwining filaments confers shear and tensile strength to the caprock, contributing to its ductility and increased resistance to fracture.

    Steam-driven eruptions, both phreatic and hydrothermal, expel exclusively fragments of non-juvenile rocks disintegrated by the expansion of water as liquid or gas phase. As their violence is related to the magnitude of the decompression work that can be performed by fluid expansion, these eruptions may occur with variable degrees of explosivity. In this study we investigate the influence of liquid fraction and rock petrophysical properties on the steam-driven explosive energy. A series of fine-grained heterogeneous tuffs from the Campi Flegrei caldera were investigated for their petrophysical properties. The rapid depressurization of various amounts of liquid water within the rock pore space can yield highly variable fragmentation and ejection behaviors for the investigated tuffs. Our results suggest that the pore liquid fraction controls the stored explosive energy with an increasing liquid fraction within the pore space increasing the explosive energy. Overall, the energy released by steam flashing can be estimated to be 1 order of magnitude higher than for simple (Argon) gas expansion and may produce a higher amount of fine material even under partially saturated conditions. The energy surplus in the presence of steam flashing leads to a faster fragmentation with respect to gas expansion and to higher ejection velocities imparted to the fragmented particles. Moreover, weak and low permeability rocks yield a maximum fine fraction. Using experiments to unravel the energetics of steam-driven eruptions has yielded estimates for several parameters controlling their explosivity. These findings should be considered for both modeling and evaluation of the hazards associated with steam-driven eruptions.

    We found the first evidence, in the last 30 years, of a renewed magmatic activity at Campi Flegrei caldera from January 2012 to June 2013. The ground deformation, observed through satellite interferometry and GPS measurements, have been interpreted as the effect of the intrusion at shallow depth (3090 ± 138 m) of 0.0042 ± 0.0002 km3 of magma within a sill. This interrupts about 28 years of dominant hydrothermal activity and occurs in the context of an unrest phase which began in 2005 and within a more general ground uplift that goes on since 1950. This discovery has implications on the evaluation of the volcanic risk and in the volcanic surveillance of this densely populated area. PMID:26279090

    Probabilistic Volcanic Hazard Assessment (PVHA) represents the most complete scientific contribution for planning rational strategies aimed at mitigating the risk posed by volcanic activity at different time scales. The definition of the space-time window for PVHA is related to the kind of risk mitigation actions that are under consideration. Short intervals (days to weeks) are important for short-term risk mitigation actions like the evacuation of a volcanic area. During volcanic unrest episodes or eruptions, it is of primary importance to produce short-term tephra fallout forecast, and frequently update it to account for the rapidly evolving situation. This information is obviously crucial for crisis management, since tephra may heavily affect building stability, public health, transportations and evacuation routes (airports, trains, road traffic) and lifelines (electric power supply). In this study, we propose a methodology for the short-term PVHA and its operational implementation, based on the model BET_EF, in which measures from the monitoring system are used to routinely update the forecast of some parameters related to the eruption dynamics, that is, the probabilities of eruption, of every possible vent position and every possible eruption size. Then, considering all possible vent positions and eruptive sizes, tephra dispersal models are coupled with frequently updated meteorological forecasts. Finally, these results are merged through a Bayesian procedure, accounting for epistemic uncertainties at all the considered steps. As case study we retrospectively study some stages of the volcanic unrest that took place in Campi Flegrei (CF) in 1982-1984. In particular, we aim at presenting a practical example of possible operational tephra fall PVHA on a daily basis, in the surroundings of CF at different stages of the 1982-84 unrest. Tephra dispersal is simulated using the analytical HAZMAP code. We consider three possible eruptive sizes (a low, a medium and a

The large uncertainty at all the steps required for the analysis, both aleatory and epistemic, is treated by means of Bayesian inference and statistical mixing of long- and short-term analyses. The BET_VHst model is here presented through its implementation during two exercises organized for volcanoes in the Neapolitan area: MESIMEX for Mt. Vesuvius, and VUELCO for Campi Flegrei.

    The thermo-rheology behaviour of the rocks is a crucial aspect to understand the mechanical behaviour of the crust of tectonically active area. As a consequence, several studies have been performed since last decades in order to clarify the role of thermic state in the evolution of volcanic areas. In this framework, the knowledge of the Brittle-Ductile transition inside the upper crust may provide insights to verify the roles that some hypothesized mechanisms, such as slab pull, crustal delamination might have played in the evolution of a tectonically active region. The goal of our study was the 3D imaging of the crust rheology beneath the active Campi Flegrei-Ischia Volcanic District and its impact on natural seismicity. Despite many works have been done on the internal structure of the active volcanoes, the determination of the 3D rheological stratification of the crust below the caldera has not yet been tackled. To fill this gap of knowledge, we proposed the definition of 3D geometry of the Brittle-Ductile transition calculated via numerical optimization modelling based on geological, geochemical, and geophysical available data. We first performed a 3D numerical modelling of thermal field by using the a priori geological and geophysical information starting to thermal proprieties and mechanical heterogeneities of the crust beneath the caldera. We developed a suitable 3D conductive/convective time-dependent thermal numerical model solving the Fourier equation and further we used the retrieved thermal model to image a 3D rheological stratification of the shallow crust below the volcanic district. Finally we demonstrate the role of the crustal rheology on seismicity cut off and its implication on maximum expected earthquakes magnitude.

    A model to describe the cloud dispersion of gas denser than air is presented here. The dispersion of heavy gas is basically governed by the gravity but, when the density contrast (gas vs air) is not important the dispersion is controlled by the wind and atmospheric turbulence (so-called “passive dispersion”). DisGas is a model for dense gases which are dispersed under passive conditions, based on the full solution of the advection-diffusion equations for the gas concentration (Sankaranarayana...

    Despite volcanic risk having been defined quantitatively more than 30 years ago, this risk has been managed without being effectively measured. The recent substantial progress in quantifying eruption probability paves the way for a new era of rational science-based volcano risk management, based on what may be termed "volcanic risk metrics" (VRM). In this paper, we propose the basic principles of VRM, based on coupling probabilistic volcanic hazard assessment and eruption forecasting with cost-benefit analysis. The VRM strategy has the potential to rationalize decision making across a broad spectrum of volcanological questions. When should the call for evacuation be made? What early preparations should be made for a volcano crisis? Is it worthwhile waiting longer? What areas should be covered by an emergency plan? During unrest, what areas of a large volcanic field or caldera should be evacuated, and when? The VRM strategy has the paramount advantage of providing a set of quantitative and transparent rules that can be established well in advance of a crisis, optimizing and clarifying decision-making procedures. It enables volcanologists to apply all their scientific knowledge and observational information to assist authorities in quantifying the positive and negative risk implications of any decision.

    Petrochemical analyses of juvenile samples from twenty stratigraphic sections of the Campanian Ignimbrite medial deposits, located from 30 to 79 km from the vent, are presented here. Sampling has accurately followed a well-defined stratigraphic framework and the new component facies scheme. The Campanian Ignimbrite succession is formed by a basal plinian pumice fall deposit, overlain by a complex architecture of pyroclastic density current deposits emplaced from a single sustained pyroclastic density current through a mechanism of vertical and lateral accretion. The deposit is broadly zoned, from more evolved trachyte at its base to less evolved trachyte at its top, and is similarly less evolved with increasing distance from the area of emission. Irregular chemical trends are locally observed and interpreted to represent only a limited, "patchy" record of the entire vertical geochemical trend. The petrochemical variation observed horizontally was ascribed to changes in the flow dynamics and interaction between the advancing flow and the underlying topography. The results of this study were used to propose a unified volcanological-petrological model for the Campanian Ignimbrite eruption, taking into account the emplacement of both the proximal (i.e., the "Breccia Museo" formation) and medial deposits.

    Structures and processes associated with shallow water hydrothermal fluid discharges on continental shelves are poorly known. We report geomorphological, geophysical, and geochemical evidences of a 5.5 x 5.3 km seabed doming located 5 km offshore the Naples harbor (Italy). The dome lies between 100 and 170 m of water depth and it is 15-20 m higher than the surrounding seafloor. It is characterized by a hummocky morphology due to 280 sub-circular to elliptical mounds, about 660 cones, and 30 pockmarks. The mounds and pockmarks alignments follow those of the main structural discontinuity affecting the Gulf of Naples. The seafloor swelling and breaching require relatively low pressures (about 2-3 MPa), and the sub-seafloor structures, which consists of 'pagodas' affecting the present-day seabed, record the active upraise, pressurization, and release of magmatic fluids. The gas composition of the sampled submarine emissions is consistent with that of the emissions from the hydrothermal systems of Ischia, CampiFlegrei and Somma-Vesuvius active volcanoes, and CO2 has a magmatic/thermometamorphic origin. The 3He/4He ratios (1.66-1.96 Ra) are slightly lower than in the Somma-Vesuvius and Campi Flegrei volcanoes (~2.6-3.0 Ra) indicating the contamination of fluids originated from the same magmatic source by crustal-derived radiogenic 4He. All these evidences concur to hypothesize an extended magmatic reservoir beneath Naples and its offshore. Seabed doming, faulting, and hydrothermal discharges are manifestations of non-volcanic unrests potentially preluding submarine eruptions and/or hydrothermal explosions. We conclude that seabed deformations and hydrothermal discharge must be included in the coastal hazard studies.

    We present the first results of a multidisciplinary research aimed at the detection and mapping of Active Fluid Vents (AFVs) at the seafloor of the Naples Bay, Italy. This segment of the Campania continental margin is characterised by severe Quaternary extension and intense volcanism at Ischia and Procida islands, the Campi Flegrei and Somma-Vesuvius volcanic complexes. High resolution hydroacoustic profilers were used to identify and localize fluid emission from the seafloor. ROV direct observation showed that each emission centre is generally composed by the coalescence of several emitting points. CTD probes showed that there are no significant gradients in temperature profiles. The results of this study include the detection and mapping of 54 fluid emission points all located in the - 71/- 158 m depth range, and spatially distributed into four main clusters. Three of the described clusters are located along the margin of a complex, toe-shaped seafloor morphology southwest of the Somma-Vesuvius, representing the shallow expression of partly buried, coalesced depositional features (namely, two flank collapses and one pyroclastic flow) associated with the Late Pleistocene activity of the volcano. The fourth AFV cluster was detected at the morphological - high, located about 8 km south of Naples (Banco della Montagna), represented by a field of volcaniclastic diapirs composed of massive pumiceous deposits originated from the Campi Flegrei intruding rising through the latest Quaternary-Holocene marine deposits. Our study suggests that the occurrence of AFV in this area could be genetically linked to the interaction between volcanic related seafloor morphologies and the main, NE striking faults present in the area, i.e. the Magnaghi-Sebeto line and the Vesuvian fault.

    The ∼ 150 km3 (DRE) trachytic Campanian Ignimbrite, which is situated north-west of Naples, Italy, is one of the largest eruptions in the Mediterranean region in the last 200 ky. Despite centuries of investigation, the age and eruptive history of the Campanian Ignimbrite is still debated, as is the chronology of other significant volcanic events of the Campanian Plain within the last 200–300 ky. New 40Ar/39Ar geochronology defines the age of the Campanian Ignimbrite at 39.28 ± 0.11 ka, about 2 ky older than the previous best estimate. Based on the distribution of the Campanian Ignimbrite and associated uppermost proximal lithic and polyclastic breccias, we suggest that the Campanian Ignimbrite magma was emitted from fissures activated along neotectonic Apennine faults rather than from ring fractures defining a Campi Flegrei caldera. Significantly, new volcanological, geochronological, and geochemical data distinguish previously unrecognized ignimbrite deposits in the Campanian Plain, accurately dated between 157 and 205 ka. These ages, coupled with a xenocrystic sanidine component > 315 ka, extend the volcanic history of this region by over 200 ky. Recent work also identifies a pyroclastic deposit, dated at 18.0 ka, outside of the topographic Campi Flegrei basin, expanding the spatial distribution of post-Campanian Ignimbrite deposits. These new discoveries emphasize the importance of continued investigation of the ages, distribution, volumes, and eruption dynamics of volcanic events associated with the Campanian Plain. Such information is critical for accurate assessment of the volcanic hazards associated with potentially large-volume explosive eruptions in close proximity to the densely populated Neapolitan region.

    In order to zone the territory of Campania Region (southern Italy) with regard to the hazard related to future explosive activity of Somma-Vesuvio, Campi Flegrei, and Ischia Island, we drew a multi-source hazard map for tephra and pyroclastic flows. This map, which merges the areas possibly endangered by the three volcanic sources, takes into account a large set of tephra fall and pyroclastic flow events that have occurred in the last 10 ka. In detail, for fall products at Campi Flegrei and Somma-Vesuvio we used the dispersal of past eruption products as deduced by field surveys and their recurrence over the whole area. For pyroclastic flows, the field data were integrated with VEI = 4 simulated events; about 100 simulations sourcing from different points of the area were performed, considering the different probability of vent opening. The spatial recurrence of products of both past eruptions and simulated events was used to assign a weight to the area endangered by the single volcanic sources. The sum of these weights in the areas exposed to the activity of two sources and/or to different kinds of products was used to draw a hazard map, which highlights the spatial trend and the extent of the single equivalent classes at a regional scale. A multi-source risk map was developed for the same areas as the graphic result of the product of volcanic hazard and exposure, assessed in detail from a dasymetric map. The resulting multi-source hazard and risk maps are essential tools for communication among scientists, local authorities, and the public, and may prove highly practical for long-term regional-scale mitigation planning.

    The Plio-Pleistocene Campanian Plain is a structural depression of the Southern Italy located between the eastern side of the Tyrrhenian Sea and the Southern Apennine chain. It is surrounded to the North, East and South by the Mesozoic carbonate massifs of the Apennine chain and, to the West, by the Tyrrhenian Sea. The graben origin is similar to other peri-Tyrrhenian regions and is related to a stretching and thinning of the continental crust by the counterclockwise rotation of the Italian peninsula and the contemporaneous opening of the Tyrrhenian sea. The consequent subsidence of the Campanian carbonate platform took place along the Tyrrhenian coast during the Plio-Pleistocene with a maximum vertical extent of 5 km. The plain is filled by volcanic and clastic, continental and marine deposits. Voluminous volcanic activity of Roccamonfina, Campi Flegrei, Ischia, Procida and Vesuvio occurred in the Plain during the Quaternary. In the middle of the plain lies the city of Naples, bordered by the two active volcanoes of Campi Flegrei and Vesuvio. It is a very densely inhabited area that is exposed to high potential volcanic risk. The stress field acting in the Campanian area is poorly known. Structural observations on the Pleistocene faults suggest normal to sinistral movements for the NW- SE-trending faults and normal to dextral for the NE-SW-trending structures. These movements are consistent with those of the structures affecting the inner margin of the Southern Apennines. The Campanian Plain is characterized by seismicity of energy lower than the seismic activity of the Southern Apennine chain. The earthquakes mainly occur along the margin of the plain, in the volcanic areas and a minor seismicity spreads out inside the Plain. The aim of this paper is an attempt to identify active, outcropping and buried fault systems of the Campanian plain through the correlation between seismicity and tectonic structures. Seismic, geologic and geomorphologic data have been

    Despite volcanic risk having been defined quantitatively more than thirty years ago, it has been always managed without being effectively measured. Yet, the recent substantial progress in quantifying eruption probability paves the way for a new era of rational science-based volcano risk management, that we name Volcanic Risk Metrics (VRM). In this talk, we propose some principles of VRM, based on two main components: a probabilistic volcanic hazard assessment and eruption forecasting, and a cost/benefit analysis. In a nutshell, the method assists managers in decision-making under uncertainty, weighing appropriately the cost and benefit of actions to mitigate the effects of a threat having a specific probability of occurrence. The strategy has the potential to rationalize decision-making across a broad spectrum of volcanological questions: what areas should be covered by emergency plan? What early preparations should be made for a volcano crisis? When should the call for evacuation be made? The strategy has the paramount advantage of providing a set of quantitative and transparent 'rules' that can be established before a crisis, optimizing and clarifying decision-making procedures. It places volcanologists at the centre of decision-making, applying all their scientific knowledge and observational information to assist authorities in quantifying the positive and negative risk implications of any decision.

    We present the first integrated tephrochronological study (major and trace elemental glass composition, Sr and Nd isotope analyses, and 40Ar/39Ar dating) for the last one tenth (∼82 m) of the ∼900 m-thick Quaternary lacustrine succession of the Fucino Basin, the largest and probably only Central Apennine intermountain tectonic depression that hosts a continuous lacustrine succession documenting the Plio-Quaternary sedimentary history up to historical times. Major element glass compositions, determined using a wavelength-dispersive electron microprobe (WDS-EMPA), yielded the geochemical fingerprinting needed for a reliable identification of most of the 23 stratigraphically ordered tephra layers under investigation. These include tephra from Italian volcanoes such as Campi Flegrei, Etna, Colli Albani, Ischia, Vico, Sabatini, and undefined volcanic sources in the Neapolitan area and Latium region. The recognition of key Mediterranean marker tephra layers (e.g. X-5 and X-6) is supported by trace element data acquired by Laser Ablation Inductively Couple Plasma Mass Spectrometry (LA-ICP-MS). The Sr and Nd isotope compositions of selected layers where also determined for circumscribing the volcanic source of distal tephra and for supporting correlations with individual eruptive units. We also propose a new, more expeditious covariation diagram (CaO/FeOtot vs Cl) for identifying the volcanic source of trachytic to phonolitic and tephrytic to phonolitic tephra, that are the most common compositions of pyroclastic rocks from volcanoes of Campania and Latium regions. Finally, we present five new 40Ar/39Ar age determinations, including a new, analytically well-supported, and more precise 40Ar/39Ar age for the widespread Y-7 tephra, and the first 40Ar/39Ar age determinations for one tephra from the Sabatini volcanic district (∼126 ka) and one tephra from Neapolitan volcanic area (Campi Flegrei?; ∼159 ka). These newly dated tephra are widely dispersed (e.g. Monticchio

It comprises roughly the last 22,000 years of landscape history consisting of a multilayered succession of repeated volcanic deposition and pedogenesis. The former is caused by several phases of volcanic activity of Somma-Vesuvius, Campi Flegrei and Ischia, reflecting a large spectrum of eruption type...

    2005-01-01

    Methane fluxes were measured, using closed chambers, in the Crater of Solfatara volcano, Campi Flegrei (Southern Italy), along eight transects covering areas of the crater presenting different landscape physiognomies. These included open bare areas, presenting high geothermal fluxes, and areas covered by vegetation, which developed along a gradient from the central open area outwards, in the form of maquis, grassland and woodland. Methane fluxes decreased logarithmically (from 150 to -4.5 mg CH4 m(-2)day(-1)) going from the central part of the crater (fangaia) to the forested edges, similarly to the CO2 fluxes (from 1500 g CO2 m(-2)day(-1) in the centre of the crater to almost zero flux in the woodlands). In areas characterized by high emissions, soil presented elevated temperature (up to 70 degrees C at 0-10 cm depth) and extremely low pH (down to 1.8). Conversely, in woodland areas pH was higher (between 3.7 and 5.1) and soil temperature close to air values. Soil (0-10 cm) was sampled, in two different occasions, along the eight transects, and was tested for methane oxidation capacity in laboratory. Areas covered by vegetation mostly consumed CH4 in the following order woodland>macchia>grassland. Methanotrophic activity was also measured in soil from the open bare area. Oxidation rates were comparable to those measured in the plant covered areas and were significantly correlated with field CH4 emissions. The biological mechanism of uptake was demonstrated by the absence of activity in autoclaved replicates. Thus results suggest the existence of a population of micro-organisms adapted to this extreme environment, which are able to oxidize CH4 and whose activity could be stimulated and supported by elevated concentrations of CH4.

    A comprehensive Probabilistic Tsunami Hazard Assessment (PTHA) should consider different tsunamigenic sources (seismic events, slide failures, volcanic eruptions) to calculate the hazard on given target sites. This implies a multi-disciplinary analysis of all natural tsunamigenic sources, in a multi-hazard/risk framework, which considers also the effects of interaction/cascade events. Our approach shows the ongoing effort to analyze the comprehensive PTHA for the city of Naples (Italy) including all types of sources located in the Tyrrhenian Sea, as developed within the Italian project ByMuR (Bayesian Multi-Risk Assessment). The project combines a multi-hazard/risk approach to treat the interactions among different hazards, and a Bayesian approach to handle the uncertainties. The natural potential tsunamigenic sources analyzed are: 1) submarine seismic sources located on active faults in the Tyrrhenian Sea and close to the Southern Italian shore line (also we consider the effects of the inshore seismic sources and the associated active faults which we provide their rapture properties), 2) mass failures and collapses around the target area (spatially identified on the basis of their propensity to failure), and 3) volcanic sources mainly identified by pyroclastic flows and collapses from the volcanoes in the Neapolitan area (Vesuvius, Campi Flegrei and Ischia). All these natural sources are here preliminary analyzed and combined, in order to provide a complete picture of a PTHA for the city of Naples. In addition, the treatment of interaction/cascade effects is formally discussed in the case of significant temporary variations in the short-term PTHA due to an earthquake.

    The Italian western coastal areas are the most exposed in the country to low-pressure systems coming from the central-western Mediterranean Sea and Atlantic Ocean. In the last years, many Italian coastal villages were struck by floods and flow processes triggered by high-intensity and short-duration rainfall, typical of flash flood events. In the Campania region (SW Italy) a series of events has caused several fatalities and heavy damages in the last decades, i.e. the flash floods of Casamicciola - Ischia Island (10/11/2009 - 1 fatality) and Atrani (9/9/2010 - 1 fatality). In this work we describe the rainfall properties and the ground effects of the 2009, 2010 and 2011 flash floods which involved the city of Pozzuoli, along the Campi Flegrei coast, where a catastrophic flood event (13 fatalities) is reported in 1918 in the AVI Project database. Rainfall data were measured at a sampling rate of 10 minutes by a regional Civil Protection rain gauge located in the city of Pozzuoli near the areas struck by the flash flood effects. In order to analyze the extreme features of the rainstorms and compare them, we have considered the 1-hour maximum rainfall amount and the 10-min peak storm intensity value for each event. The first rainstorm occurred on 14 September 2009; it was characterized by a 1-hour maximum rainfall amount of 34.4 mm and a 10-min peak storm intensity of 57.6 mm/h. The second rainstorm occurred on 30 July 2010; it was characterized by a 1-hour maximum rainfall amount of 40.6 mm and a 10-min peak storm intensity of 126 mm/h. The third rainstorm occurred on 06 November 2011; it was characterized by a 1-hour maximum rainfall amount of 44.2 mm and a 10-min peak storm intensity of 67.2 mm/h. The three described rainstorms all triggered erosional processes and shallow landslides in the upper part of the Pozzuoli drainage basin that supplied sheet flows and hyperconcentrated flows downstream, with severe damage to the human structures built near or inside the

    Full Text Available The possible emplacement of pyroclastic fall and flow products from Campi Flegrei and Somma-Vesuvio represents a threat for the population living in Napoli city. For this area, the volcanic hazard was always partially investigated to define the hazard related to the Campi Flegrei or to the Somma-Vesuvio activity one at a time. A new volcanic hazard and risk assessment, at the municipality scale, as a vital tool for decision-making about territorial management and future planning, is presented here.

    In order to assess the hazard related to the explosive activity of both sources, we integrated the results of field studies and numerical simulations, to evaluate the future possibility for Napoli to be hit by the products of an explosive eruption. This is defined for the Somma Vesuvio central volcano through the sum of "field frequency" based on the thickness and distribution of past deposits (Lirer et al., 2001, and for the Campi Flegrei volcanic field by suitably processing simulated events based on numerical modelling (Alberico et al., 2002; Costa et al., 2009. Aiming at volcanic risk assessment, the hazard areas were joined with the exposure map, considered for our purposes as the economical value of artefacts exposed to hazard. We defined four risk classes, and argued that the medium and low-very low risk classes have the largest extent in Napoli municipality, whereas only few zones located in the eastern part of the city and in the westernmost coastal area show a high risk, owing to the correspondence of high economical value and high hazard.

    The Phlegrean volcanic district (PVD) in southern Italy is one of the best known volcanic hazard areas in the world. More than 1.5 million people live in close proximity to the volcanic centers. The PVD comprises three volcanic fields: the Campi Flegrei caldera and the islands of Ischia and Procida. We studied volatiles plus major and trace elements in the magma associated with the Solchiaro eruption on the Island of Procida, Italy, to gain a better understanding of the relationship between pre-eruptive volatiles and magmatic evolution. The Solchiaro eruption is one of the more primitive products erupted in the PVD and provides information on the source of later more evolved magmas associated with this volcanic system. The composition of the magma before eruption was determined by analyzing 104 melt inclusions (MIs) in forsteritic olivine, glass embayment plus rim glasses, and high vesciculated glasses selected from 4 representative samples. The composition of MIs was recalculated and ranges from basaltic to trachy-basaltic. Among major elements potassium shows the highest variability, from 0.5 to 6 wt%. MI define a continuous trend based on major and minor element compositions. Embayments matrix glass and high vesciculated glasses define a field that suggests a discontinuous process. Compatible to incompatible trace element ratios in early melts are highly variable and represent the melt phase before or at the very beginning of assimilation-fractional crystallization (FCA) processes. Intermediate melt compositions reflect continuing FCA processes, late melt compositions suggest that the FCA process was aborted before eruption. Volatile contents of early melt are highly variable and reflect source heterogeneities, and the melts are interpreted to be undersaturated. Intermediate melts were volatile saturated and H2O-CO2 contents define a degassing path. Depths of trapping of MI range from 4.4 to 2.2 km, and are calculated based on Newman and Lowenstern (2002) and

    Ground deformation signals such as dilatometric and tiltmetric ones, are nowadays well studied from the vulcanological community all over the world. These signals can be used to retrieve information on volcanoes state and to study the magma dynamics in their plumbing system. We compared synthetic signals in the Very Long Period (VLP, 10-2 - 10-1 Hz) and Ultra Long Period (ULP, 10-4 - 10-2 Hz) bands obtained from the simulation of magma mixing in shallow reservoirs ([3],[4]) with real data obtained from the dilatometers and tiltmeters network situated in the Phlegraean Fields near Naples (Italy), in order to define and constrain the relationships between them. Analyses of data from the October 2006 seismic swarm in the area show that the frequency spectrum of the synthetics is remarkably similar to the transient present in the real signals. In depth studies with accurated techniques for spectral analysis (i.e wavelet transform) and application of this method to other time windows have identified in the bandwidth around 10-4Hz (between 1h30m and 2h45m) peaks that are fairly stable and independent from the processing carried out on the full-band signal. These peaks could be the signature of ongoing convection at depth. It is well known that re-injection of juvenile magmas can reactivate the eruption dynamics ([1],[2]), thus being able to define mixing markers and detect them in the ground deformation signals is a relevant topic in order to understand the dynamics of active and quiescent vulcanoes and to eventually improve early-warning methods for impending eruptions.

    Melt inclusions in phenocrysts from some shoshonite to latite eruptive products of Ischia Island (Southern Italy) provide a window on the deep magmatic feeding system. Together with similar products from the other Neapolitan volcanoes (Procida, Campi Flegrei and Somma-Vesuvius), they probe the deep physico-chemical conditions of magmas generated in a mantle contaminated by slab derived fluids/melts largely dominated by CO2. The analyzed melt inclusions bear clear evidence for CO2 dominated gas fluxing and consequent dehydration of magma portions stagnating at major crustal discontinuities. In general, magma differentiation at Ischia takes place under very oxidized conditions determined by an unusual, nearly equimolar, proportion of divalent and trivalent iron in the melt. Budgets of magma degassing show that at Ischia there is much less magma than that needed to directly supply the amount of magmatic fluids released at surface, thus constraining the role of CO2 rich deep fluids in originating the volcanism and generating caldera resurgence. The acquired data, together with those from the other Neapolitan volcanoes, show that, despite the compositional and eruptive style differences within the poorly extended Neapolitan Volcanic area, the different kinds of volcanism are linked by supercritical CO2 fluids produced by devolatilization of subducted terrigenous-carbonatic metasediment, that infiltrate the mantle wedge, generate magmas and control their ascent up to eruption. In particular, fluid upraise and accumulation at crustal levels beneath Neapolitan volcanoes occurs with different flow-rates that depend on the major geological structures, particularly NW-SE normal and NE-SW transfer regional fault systems.

  8. A preliminary probabilistic analysis of tsunami sources of seismic and non-seismic origin applied to the city of Naples, Italy

    In both worldwide and regional historical catalogues, most of the tsunamis are caused by earthquakes and a minor percentage is represented by all the other non-seismic sources. On the other hand, tsunami hazard and risk studies are often applied to very specific areas, where this global trend can be different or even inverted, depending on the kind of potential tsunamigenic sources which characterize the case study. So far, few probabilistic approaches consider the contribution of landslides and/or phenomena derived by volcanic activity, i.e. pyroclastic flows and flank collapses, as predominant in the PTHA, also because of the difficulties to estimate the correspondent recurrence time. These considerations are valid, for example, for the city of Naples, Italy, which is surrounded by a complex active volcanic system (Vesuvio, Campi Flegrei, Ischia) that presents a significant number of potential tsunami sources of non-seismic origin compared to the seismic ones. In this work we present the preliminary results of a probabilistic multi-source tsunami hazard assessment applied to Naples. The method to estimate the uncertainties will be based on Bayesian inference. This is the first step towards a more comprehensive task which will provide a tsunami risk quantification for this town in the frame of the Italian national project ByMuR (http://bymur.bo.ingv.it). This three years long ongoing project has the final objective of developing a Bayesian multi-risk methodology to quantify the risk related to different natural hazards (volcanoes, earthquakes and tsunamis) applied to the city of Naples.

    Volcanology in Italy and in the world has rapidly developed during last decades. In the Seventies, stratigraphy and petrology provided the basic knowledge on the volcanic activities that still forms the root for modern volcano research. During the Eighties and Nineties the interest was more on the quantitative description of the volcanic processes, with enormous progresses in different but complementary fields including laboratory measurements and experiments, physico-mathematical modeling and numerical simulations, geophysical surveys and inverse analysis, and volcano monitoring and surveillance. In year 2000 a large number of magma properties and magmatic and volcanic processes was characterized at a first or higher order. Volcano research in Italy during the first decade of the new millennium has further developed along those lines. To-date, the very high risk Campi Flegrei and Vesuvius volcanoes, and the less risky but permanently active Etna and Stromboli volcanoes, are among the best monitored and more deeply investigated worldwide. The last decade has also seen coordinated efforts aimed at exploring exploitation of knowledge and skills for the benefit of the society. A series of projects focused on volcanic hazard and risk have joined >1000 researchers from Italian and foreign (Europe, US, Japan) Universities and Research Centers, on themes and objectives jointly defined by scientists from INGV and end-users from the national Civil Protection Department. These projects provide a global picture of volcano research in year 2010, that appears to be evolving through i) further rapid developments in the fields of investigation listed above, ii) their merging into effective multidisciplinary approaches, and iii) the full inclusion of the concepts of uncertainty and probabilities in volcanic scenario predictions and hazard forecast. The latter reflects the large inaccessibility of the volcanic systems, the extreme non-linear behaviour of volcanic processes put in

  11. Geodetic Monitoring System Operating On Neapolitan Volcanic Area (southern Italy)

    Pingue, F.; Ov-Geodesy Team

    The Neapolitan volcanic area is located in the southern sector of the Campanian Plain Graben including three volcanic active structures (Somma-Vesuvius, Campi Flegrei and Ischia). The Somma-Vesuvius complex, placed East of Naples, is a strato-volcano composed by a more ancient apparatus (Mt. Somma) and a younger cone (Mt. Vesu- vius) developed inside Somma caldera. Since last eruption (1944) it is in a quiescent state characterised by a low level seismicity and deformation activity. The Campi Fle- grei, located West of Naples, are a volcanic field inside an older caldera rim. The last eruption, occurred in the 1538, built up the Mt. Nuovo cone. The Campi Flegrei are subject to a slow vertical deformation, called bradyseism. In the 1970-1972 and 1982-1984 they have been affected by two intense episodes of ground upheaval (ac- companied by an intense seismic activity)0, followed by a subsidence phase, slower than uplift and still active. Though such phenomenon has not been followed by erup- tive events, it caused serious damages, emphasizing the high volcanic risk of the phle- grean caldera. The Ischia island, located SW of Naples, has been characterised by a volcanic activity both explosive and effusive, occurred mainly in the last 50,000 years. These events modelled the topography producing fault systems and structures delim- iting the Mt. Epomeo resurgent block. The last eruption has occurred on 1302. After, the dynamics of the island has been characterised by seismic activity (the strongest earthquake occurred on 1883) and by a meaningful subsidence, on the S and NW sec- tors of the island. The concentration of such many active volcanoes in an area with a dense urbanization (about 1,500,000 inhabitants live) needs systematic and contin- uous monitoring of the dynamics. These information are necessary in order to char- acterise eruptive precursors useful for modelling the volcanoes behaviour. Insofar, the entire volcanic Neapolitan area, characterised by a

    The Solfatara-Pisciarelli (S-P) area was characterized by an intense eruptive activity during the last 5 ka and is presently the highly distributed degassing zones inside the CFC, worldwide well-known for its bradyseismic phenomenon. The last two main crises occurred during the 1970-72 and 1982-84, associated with an overall 3.5 m of ground uplift and an elevate rate of low magnitude seismicity. A strong direct relationship has always been observed between the increase of hydrothermal activity in the S-P area and ground uplift of the CFc. More recently starting from the 2005 a new gradual increase of the hydrothermal activity and ground uplift has been observed, with a steep growth of these effects from 2012, accompanied by seismic events with highest magnitude of 1.8. The Pisciarelli area has been the site of a significant morphological changes of its hydrothermal field including new fumarolic vents and a wide enlargement of a mud pool. Monitoring either landscape deformation than fluids migration of the S-P activity can be considered a good indicator of the volcanic dynamics taking place in the whole CFc caldera. This study shows a first attempt to integrate multidisciplinary approach including volcanological and structural field surveys and studies such us TLS and ERT signals applied to this highly dynamic areas. A detailed geo-structural survey allow us to characterize the complex pattern of fractures and faults recorded in the volcanic rocks in different times of the polyphasic CFc volcanic history. In order to statistically record data about fault and fracture (i) attitudes and (ii) spacing, the scan line method was applied. The whole planar structure is the locus of the well-known fumaroles and mud pools of Pisciarelli. A first time detailed Digital Terrestrial Model DTM of the area with an accuracy of 5cm obtained through TLS has been integrated combining the ERT of the lower part of the area, characterized by a widespread fumarolic activity and soil diffuse degassing, mainly in correspondence to fractures and faults. The TLS analysis of the area was performed applying the technique based on Time of Flight method in order to define an accurate 3D digital model for detailed analysis of this area. Several scans were performed in order to avoid shaded areas due to the presence of either fumaroles than soil degassing. The dense vapour emission in the area, in fact limits the ability of penetration of the laser scanner. Electrical measurements has been acquired to reconstruct the spatial distribution of the electrical resistivity, which is a physical parameter particularly sensitive to the presence of low-resistivity phases, such as aqueous fluids and partial melts. In such a way, the volume of subsurface fluids has been constrained and the rheology of the subsoil in the Pisciarelli area has been reconstructed. Combining all the data a structural and geomorphological model of the area has been obtained. Similar dataset could be acquired in the future in order to estimate any structural changes that may occur in this interesting volcanic area therefore providing a better hazard assessment.

    Lake Patria is a mesoaline coastal lagoon that develops along the coastal zone of the Volturno River plain (Campania, South Italy). The lagoon is a saline to brackish water body, ca. 2.0 long, and 1.5 km wide, with an average water depth of 1.5 m, reaching a maximum of ca. 3.0 m. The freshwater input into the lagoon is provided by a series of fresh to brackish water channels and small springs, landwards, while a permanent connection with the Tyrrhenian Sea is provided by a channel, 1.5 km long and a few meters wide. Drilling data from 12 boreholes acquired in the study area indicate that Lake Patria is a man-modified remnant of a larger lagoonal area that developed during the last millennia along the Campania coastal zone within an alluvial delta system at the mouth of the paleo-Volturno River. Sedimentological and stratigraphic analyses of drill cores suggest that the lower Volturno delta plain developed in the last 6000 years. Depositional conditions during this period were dominated by flood-plain and alluvial plain settings, with transition to coastal bars and associated back-barrier coastal lagoons. Lake Patria started evolving at an early stage of the Volturno delta plain formation as a consequence of foreshore deposits damming-up by littoral drift. The first marine layers display a radiocarbon age of ca. 4.8 ka BP and overlie a substrate represented by volcaniclastic deposits, originated by the Campi Flegrei, and associated paleosols. The lagoonal succession cored at Lake Patria may be interpreted as the result of a dynamic equilibrium between marine influence and riverine input into the lagoonal system through time, and has been tentatively correlated with the major climatic changes that occurred during Mid-Late Holocene. Insights into the recentmost evolution of the coastal lagoon of Lake Patria are provided by the GIS-based analysis of the physiographic changes of the region conducted on a series of historical topographic maps dating back to the early

    The Ischia island is a large, complex, partly submerged, active volcanic field located about 20 km east to the Campi Flegrei, a major active volcano-tectonic area near Naples. The island is morphologically characterized in its central part by the resurgent block of Mt. Epomeo, controlled by NW-SE and NE-SW trending fault systems, by mountain stream basin with high relief energy and by a heterogeneous coastline with alternation of beach and tuff/lava cliffs in a continuous reshape due to the weather and sea erosion. The volcano-tectonic process is a main factor for slope stability, as it produces seismic activity and generated steep slopes in volcanic deposits (lava, tuff, pumice and ash layers) characterized by variable strength. In the Campi Flegrei and surrounding areas the possible occurrence of a moderate/large seismic event represents a serious threat for the inhabitants, for the infrastructures as well as for the environment. The most relevant seismic sources for Ischia are represented by the Campi Flegrei caldera and a 5 km long fault located below the island north coast. However those sources are difficult to constrain. The first one due to the on-shore and off-shore extension not yet completely defined. The second characterized only by few large historical events is difficult to parameterize in the framework of probabilistic hazard approach. The high population density, the presence of many infrastructures and the more relevant archaeological sites associated with the natural and artistic values, makes this area a strategic natural laboratory to develop new methodologies. Moreover Ischia represents the only sector, in the Campi Flegrei area, with documented historical landslides originated by earthquake, allowing for the possibility of testing the adequacy and stability of the method. In the framework of the Italian project MON.I.C.A (infrastructural coastlines monitoring) an innovative and dedicated probabilistic methodology has been applied to identify

Specifically, we used a theoretical framework to describe and assess the relationships between urbanization and farm-styles in the city belt. Our analysis is based on a case study in the protected area of the Campi Flegrei Regional Park situated in the north-western part of the Neapolitan metropolitan area, which is a peri-urban rural area with severe environmental management problems. Our results from the empirical analysis allowed us to distinguish the farms of the area into three behavioural-social groups on the basis of specific features, in order to identify the best suited type of farm for the strategic implementation of the CSA. A market scenario was predicted for each of them without any intervention

    The correct definition of the background level of ground deformation is a very important aspect in geodetic monitoring of volcanic areas. Indeed, it could allow a fast identification of an anomalous deformation trend that evolves towards an eruptive event. It is interesting confirm that any ground deformation modifies the distribution of the time series amplitude so significantly that this behaviour could be used as the marker of an effective source driven deformation. As an example, we analyse the site position time series of Neapolitan Volcanic Continuous GPS (NeVoCGPS) network operating on three volcanic active districts (Somma-Vesuvius volcano, Campi Flegrei Calder and Ischia Island) in a densely inhabited area, recorded during the period 2001-2007. These GPS time series reveal a very peculiar behaviour. When a clear deformation is observed, the amplitude distribution evolves from a gaussian to a bivariate gaussian distribution. This behaviour can be characterized by evaluating the kurtosis. The time series for all stations have been modelled with a fifth order polynomial fit. This represents the deformation history. Indeed, when this polynomial is subtracted from the time series, the distributions become again gaussian. A simulation of the deformation time evolution reveals that the amplitude distribution evolves towards a non gaussian behaviour if the ground deformation starts at 2/3 of the time series duration.

  20. Italian super-eruption larger than thought

    Science.gov (United States)

    Schultz, Colin

    2012-07-01

    Recent research suggested that the super-eruption of the Campi Flegrei caldera volcano in southern Italy about 40,000 years ago may have played a part in wiping out, or forcing the migration of, the Neanderthal and modern human populations in the eastern Mediterranean regions that were covered in ash. Now a new modeling study by Costa et al. suggests that this eruption may have been even larger than previously thought. This Campi Flegrei eruption produced a widespread ash layer known as Campanian Ignimbrite (CI). Using ash thickness measurements collected at 115 sites and a three-dimensional ash dispersal model, the researchers found that the CI super-eruption would have spread 250-300 cubic kilometers of ash across a 3.7-million-square kilometer region—2 to 3 times previous ash volume estimates.

    Major, minor and trace element analysis of volcanic glass in proximal and distal (Lipari (Monte Pilato; 776 cal AD); (2) Vulcano; and (3) Campi Flegrei (Soccavo 1; 11,915-12,721 cal years BP). Whether a polymictic coarse grained volcaniclastic turbidite in the Marsili Basin originated from collapse on Salina remains unresolved because multi-elemental analysis raises doubt about the published correlation to the Pollara region. It is evident that correlation of proximal continental and distal marine tephras, at a high level of confidence, requires a full complement of major, minor and trace element data. In conjunction with considerations of the mineralogy and morphology of juvenile deposits these data help define petrological lineages such that precise provenance can be established. Whilst a precise proximal-distal match must be based on identical major, minor and trace element concentrations it is clear that resurgent activity from a single volcano can produce magmas with identical compositions. In such cases stratigraphic relationships must complement any geochemical study. Occasionally proximal stratigraphies may be unrepresentative of the complete eruptive history because of a lack of exposure due to burial by more recent effusive and explosive activity, or sector collapse which can remove vital stratigraphy particularly on volcanic islands.

  4. Preliminary results on the comparison between satellite derived ground temperature and in-situ measurement of soil CO2 flux and soil temperature at Solfatara of Pozzuoli (Naples, Italy)

    In this work we want to analyze the comparison between the ground temperature acquired with in-situ campaigns and the ground temperature obtained by processing remote sensing data with particular attention to ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) data. Moreover we have studied the possible correlation between the CO2 measurements and the ground temperature. Test site area has been the Solfatara volcano, situated to the west of Naples, Italy. The Solfatara crater has a persistent volcanic-hydrothermal activity as demonstrate by ground deformation, seismicity and variations of the chemical-physical characteristics of the fluids emitted from fumaroles. Solfatara crater is characterized by a large soil diffuse degassing structure (Solfatara DDS, abot 0.8 km2), from where a CO2 flux in the order of 1000-1500 t/d is released by the soil. Solfatara DDS is also characterized by anomalous soil temperature. The correspondence between high CO2 fluxes and soil temperature has been interpreted as the results of the condensation of CO2-rich steam, rising from the hydrothermal system, in the uppermost part of the soil (Chiodini et al., 2001; 2005). The energy dissipated daily by the degassing at Solfatara DDS is the main source of energy release in the entire Campi Flegrei caldera in the current period (Chiodini et al., 2001; 2005). Concerning the satellite data, to monitor the thermal state of volcanic areas it is necessary to use TIR sensors with high spatial resolution in order to obtain detailed information on the areas where there are significant changes. Thanks to ASTER thermal infrared (TIR, 5 bands, 90 m spatial resolution) regions of the electromagnetic spectrum we have obtained the temperature ground map on the volcano area. For this study we have considered the ASTER's night observations that show well defined episodes of increasing thermal emission of crater thanks to a more uniform background temperature.

    Imaging shallow subsurface structures and monitoring related temporal variations are two of the main tasks for modern geosciences and seismology. Although many observations have reported temporal velocity changes, e.g., in volcanic areas and on landslides, new methods based on passive sources like ambient seismic noise can provide accurate spatially and temporally resolved information on the velocity structure and on velocity changes. The success of these passive applications is explained by the fact that these methods are based on surface waves which are always present in the ambient seismic noise wave field because they are excited preferentially by superficial sources. Such surface waves can easily be extracted because they dominate the Greeńs function between receivers located at the surface. For real-time monitoring of the shallow velocity structure of the Solfatara crater, one of the forty volcanoes in the Campi Flegrei area characterized by an intense hydrothermal activity due to the interaction of deep convection and meteoric water, we have installed a dense network of 50 seismological sensing units covering the whole surface area in the framework of the European project MED-SUV (The MED-SUV project has received funding from the European Union Seventh Framework Programme FP7 under Grant agreement no 308665). Continuous recordings of the ambient seismic noise over several days as well as signals of an active vibroseis source have been used. Based on a weighted inversion procedure for 3D-passive imaging using ambient noise cross-correlations of both Rayleigh and Love waves, we will present a high-resolution shear-wave velocity model of the structure beneath the Solfatara crater and its temporal changes. Results of seismic tomography are compared with a 3-D electrical resistivity model and CO2 flux map.

    This paper presents new data on the baseline concentrations of U, Th and K in 2389 stream sediments over the whole Campania region. These data, based on systematic sampling and analysis, are compared with those obtained by gamma-ray spectrometry surveys. Variations in the U, Th and K concentration in the surficial environment of the Campania region appear to be related to bedrock lithology. Generally, high U, Th and K values in stream sediments correspond well with the occurrence of volcanic rocks in the central-western part of the region, whereas low values are found in areas characterized by silico-clastic and carbonate deposits, occurring mostly in the southern and eastern part of the region. Gamma-ray spectrometry maps show a similar pattern, although the distribution of the highest radioactivity levels define more restricted areas than the ones resulting from mapping stream sediment geochemistry. Particularly high {sup 40}K radioactivity levels delimit all the known eruptive centers (Roccamonfina, Campi Flegrei and Somma-Vesuvius), including the fissural sources of Campania Ignimbrites, much better than U and Th radioactivity. One of the concerns for human health in the Campania region is the total gamma radiation and Rn potential related mostly to alkaline volcanics of the Neapolitan volcanological province. In particular, geothermal activity occurring in all the Campanian volcanic areas represents a potential hazard for Rn gas.

    Campylobacter spp. cause foodborne illnesses in humans primarily through the consumption of contaminated chicken. The aim of this study was to evaluate the United States Department of Agriculture's (USDA) recommended methodology, protocol MLG 41.02, for the isolation, identification and direct plate counting of Campylobacter jejuni and C. coli samples from the broiler slaughtering process. A plating method using both mCCDA and Campy-Cefex agars is recommended to recover Campylobacter cells. It is also possible to use this method in different matrices (cloacal swabs and water samples). Cloacal swabs, samples from pre-chiller and post-chiller carcasses and samples of pre-chiller, chiller and direct supply water were collected each week for four weeks from the same flock at a slaughterhouse located in an abattoir in southern Brazil. Samples were analyzed to directly count Campylobacter spp., and the results showed a high frequency of Campylobacter spp. on Campy-Cefex agar. For the isolated species, 72% were identified as Campylobacter jejuni and 38% as Campylobacter coli. It was possible to count Campylobacter jejuni and Campylobacter coli from different samples, including the water supply samples, using the two-agar method. These results suggest that slaughterhouses can use direct counting methods with both agars and different matrices as a monitoring tool to assess the presence of Campylobacter bacteria in their products.

    Full Text Available Resumo No cenário urbano, a distribuição da vegetação e seus aspectos de qualidade ambiental repercutem nos modos de vida das populações em termos de saúde e qualidade de vida. O investimento em espaços verdes, com ampla variedade de elementos naturais, pode promover a redução dos níveis de estresse e fadiga mental. Em ambientes universitários, por exemplo, os estudantes sentem-se constantemente fatigados devido às exigências para um bom desempenho. Considerando pesquisas na área de Psicologia Ambiental que têm constatado os benefícios para a saúde provenientes do contato com espaços verdes, esse estudo buscou identificar lugares escolhidos por estudantes para descanso em dois campi universitários brasileiros. Explorou ainda elementos de preferências e percepções ambientais associadas à capacidade restaurativa desses espaços. A entrevista, associada a uma variação da técnica de ambiente fotografado, possibilitou a análise das características desses espaços. As escolhas citadas pelos 50 alunos de cada campus direcionaram a discussão. Os discursos dos discentes revelaram possibilidades de restauro psicológico no ambiente universitário. Em ambos os campi, o contato com espaços verdes abertos pareceu estar associado a momentos de interação entre pessoas e o ambiente, de maneira mais ativa ou mais passiva. No campus 2, as interações com os espaços verdes foram predominantemente ativas, apesar do campus 1 ter área de vegetação mais extensa. Dessa forma, compreende-se que a vivência restauradora se dá na relação pessoa-ambiente e é permeada por sutilezas que perpassam distintas realidades sociais.

  1. Conscientious objection in Italy.

    Minerva, Francesca

    2015-02-01

    The law regulating abortion in Italy gives healthcare practitioners the option to make a conscientious objection to activities that are specific and necessary to an abortive intervention. Conscientious objectors among Italian gynaecologists amount to about 70%. This means that only a few doctors are available to perform abortions, and therefore access to abortion is subject to constraints. In 2012 the International Planned Parenthood Federation European Network (IPPF EN) lodged a complaint against Italy to the European Committee of Social Rights, claiming that the inadequate protection of the right to access abortion implies a violation of the right to health. In this paper I will discuss the Italian situation with respect to conscientious objection to abortion and I will suggest possible solutions to the problem.

    This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image of Mt. Vesuvius, Italy was acquired September 26, 2000. The full-size false-color image covers an area of 36 by 45 km. Vesuvius overlooks the city of Naples and the Bay of Naples in central Italy. (Popocatepetl and Mount Fuji are other volcanos surrounded by dense urban areas.) In 79 AD, Vesuvius erupted cataclysmically, burying all of the surrounding cites with up to 30 m of ash. The towns of Pompeii and Herculanaeum were rediscovered in the 18th century, and excavated in the 20th century. They provide a snapshot of Roman life from 2000 years ago: perfectly preserved are wooden objects, food items, and the casts of hundreds of victims. Vesuvius is intensively monitored for potential signs of unrest that could signal the beginning of another eruption. Image courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team

    This article describes the history and the prevailing orientations of group psychotherapy in Italy (psychoanalytically oriented, psychodrama, CBT groups) and particularly group analysis. Provided free of charge by the Italian health system, group psychotherapy is growing, but its expansion is patchy. The main pathways of Italian training in the different group psychotherapy orientations are also presented. Clinical-theoretical elaboration on self development, psychopathology related to group experiences, and the methodological attention paid to objectives and methods in different clinical groups are issues related to group therapy in Italy. Difficulties in the relationship between research and clinical practice are discussed, as well as the empirical research network that tries to bridge the gap between research and clinical work in group psychotherapy. The economic crisis in Italy has led to massive cuts in health care and to an increasing demand for some forms of psychological treatment. For these reasons, and because of its positive cost-benefit ratio, group psychotherapy is now considered an important tool in the national health care system to expand the clinical response to different forms of psychological distress.

    This paper describes the role of social cooperatives in Italy as a type of economic, non-profit organization and their role in contributing to the economic and social growth of the country. The purpose of this paper is to learn more about the experience of the Italian social cooperatives in promoting the work integration process of disadvantaged workers, especially those suffering from mental disorders, from a theoretical and an empirical point of view. Social enterprise is the most popular and consolidated legal and organizational model for social enterprises in Italy, introduced by Law 381/91. Developed during the early 1980s, and formally recognized by law in the early 1990s, social cooperatives aim at pursuing the general interest of the community to promote the human needs and social inclusion of citizens. They are orientated towards aims that go beyond the interest of the business owners, the primary beneficiary of their activities is the community, or groups of disadvantaged people. In Italy, Law 381/91 distinguishes between two categories of social cooperatives, those producing goods of social utility, such as culture, welfare and educational services (A-type), and those providing economic activities for the integration of disadvantaged people into employment (B-type). The main purpose of B-type social cooperatives is to integrate disadvantaged people into the open labour market. This goal is reached after a period of training and working experience inside the firm, during which the staff works to improve both the social and professional abilities of disadvantaged people. During the years, B-type social co-ops acquired a particular relevance in the care of people with mental disorders by offering them with job opportunities. Having a job is central in the recovery process of people suffering from mental diseases, meaning that B-type social co-ops in Italy play an important rehabilitative and integrative role for this vulnerable population of workers.

    Full Text Available In the European extent, Italy is the cradle of libraries and library sciences. In the past, Italian national public libraries played an important role through their vast book treasury. But only during the last thirty years have public libraries been developed following the Anglo-American public library model. Italy does not have any uniform or general legislation concerning libraries. On the state level, this area is regulated by some separate acts, while on the regional level there is a collection of various acts and regulations. Libraries are not strictly divided into general categories. It is required that the professionals engaged in Italian libraries should have secondary or university education. The level of their professional tasks depends on the type of library and its capacity. The competency for the development in the field of librarianship is assigned to The Ministry of Cultural and Environment Heritage as well as to its subordinate institutions (Central Institute for the Union catalogue of Italian Libraries and for Bibliographic Information, Central Institute for Book Pathology, Observatory for International Libraries Programmes.

  9. Gestalt psychology in Italy.

    Science.gov (United States)

    Verstegen, I

    2000-01-01

    Graz gestalt psychology was introduced into Italy after World War I with Vittorio Benussi's emigration to Padua. His earliest adherent, Cesare Musatti, defended Graz theory, but after Benussi's premature death became an adherent of the Berlin gestalt psychology of Wertheimer-Köhler-Koffka. He trained his two most important students, Fabio Metelli and Gaetano Kanizsa, in orthodox Berlin theory. They established rigid "schools" in Padua and Trieste. The structure of Italian academics allowed for such strict orthodoxy, quite unlike the situation in America, where scientific objectivity mitigated against schools. In the 1960s, some of the students of Metelli and Kanizsa (above all Bozzi) initiated a realist movement-felt in Kanizsa's late work-that was quite independent of that of J. J. Gibson. Finally, more recently, Benussi and Graz theorizing have been embraced again, sentimentally, as a predecedent to Kanizsa-Bozzi.

  14. Late-stage volatile saturation as a potential trigger for explosive volcanic eruptions

    Science.gov (United States)

    Stock, Michael J.; Humphreys, Madeleine C. S.; Smith, Victoria C.; Isaia, Roberto; Pyle, David M.

    2016-03-01

    Magma reservoirs are thought to grow relatively slowly, assembling incrementally under volatile-saturated conditions. Eruptions may be triggered by injections of volatile-rich melt, or generation of over-pressure due to protracted crystallization. Here, we analyse fluorine, chlorine and water in apatite crystals trapped at different stages of magma evolution, and in melt inclusions from clinopyroxene and biotite crystals expelled during an explosive eruption of the Campi Flegrei caldera, Italy, about 4,000 years ago. We combine our geochemical analyses with thermodynamic modelling to reconstruct the evolution of magmatic volatile contents leading up to the explosive eruption. We find that the magma reservoir remained persistently water-undersaturated throughout most of its lifetime. Even crystals in contact with the melt shortly before eruption show that the magma was volatile-undersaturated. Our models suggest that the melt reached volatile saturation at low temperatures, just before eruption. We suggest that late-stage volatile saturation probably triggered the eruption, and conclude that `priming’ of the magma system for eruption may occur on timescales much shorter than the decadal to centennial timescales thought typical for magma reservoir assembly. Thus, surface deformation pulses that record magma assembly at depth beneath Campi Flegrei and other similar magmatic systems may not be immediately followed by an eruption; and explosive eruptions may begin with little warning.

  15. A new frontier in CO2 flux measurements using a highly portable DIAL laser system

    Science.gov (United States)

    Queiβer, Manuel; Granieri, Domenico; Burton, Mike

    2016-01-01

    Volcanic CO2 emissions play a key role in the geological carbon cycle, and monitoring of volcanic CO2 fluxes helps to forecast eruptions. The quantification of CO2 fluxes is challenging due to rapid dilution of magmatic CO2 in CO2-rich ambient air and the diffuse nature of many emissions, leading to large uncertainties in the global magmatic CO2 flux inventory. Here, we report measurements using a new DIAL laser remote sensing system for volcanic CO2 (CO2DIAL). Two sites in the volcanic zone of Campi Flegrei (Italy) were scanned, yielding CO2 path-amount profiles used to compute fluxes. Our results reveal a relatively high CO2 flux from Campi Flegrei, consistent with an increasing trend. Unlike previous methods, the CO2DIAL is able to measure integrated CO2 path-amounts at distances up to 2000 m using virtually any solid surface as a reflector, whilst also being highly portable. This opens a new frontier in quantification of geological and anthropogenic CO2 fluxes. PMID:27652775

  20. Fatto in Italia: Refashioning Italy

    Full Text Available This article discusses how the Made in Italy brand helped Italy to recover from economic recession in the 1980s, but also how it redefined the country's identity after the traumatic years of terrorism and especially after the murder of the Christian Democratic Party Secretary, Aldo Moro, at the hands of the Red Brigades. In this period cinema as a form of artistic achievement declined, while fashion and industrial design moved at the centre stage of economic and creative success. The rampant consumerism of the 1980s, fuelled by tax reforms that favoured a wider urban middle class, the retreat of unionism, the abandonment of collective bargaining in many industrial sectors, industrial restructuring with the consequent growth of black market economy in the provincial areas of the so-called Third Italy first and the South later, were all factors that contributed to a social and economic shift within Italy itself. Commercial consumption, propagated by the proliferation of local commercial television networks, hedonism and a re-articulation of identity through appearance replaced the 1970s' political activism and ideological opposition to fashion. Ultimately, 'Made in Italy' was a multidimensional phenomenon that presented itself as a new cultural model for the country’s political tribes of the 1970s.

    Full Text Available The essay explores the impact of poetry translation on the circulation of the works of American poets in Italy. The research is conducted by means of a double approach: in the first place, the aesthetic and cultural value of the poetry of two American women poets (Jorie Graham and Mary Oliver is assessed, whose work has received a radically different reception. Secondly, the reasons for this disparity of treatment are sought in the interrelation between the practices and activity of poetry translation and of publication, as they are customarily led in Italy. These are inferred from sample interviews with professionals in both fields. The results of the investigation highlight a combination of the casual and the causal, the causing factor being the occasional encounter of a poet with a translator, who then chooses his/her author, texts, and translating strategies according to his/her personal aesthetic, and sometimes ideological, judgment. Il saggio offre un’analisi dell’influenza delle traduzioni sulla circolazione della poesia americana contemporanea in Italia. La ricerca si articola in due momenti: in primo luogo viene fornita una valutazione estetica e culturale dell’opera di due poetesse americane, Jorie Graham e Mary Oliver, la cui ricezione in Italia è particolarmente significativa perché sta conoscendo fortune opposte; in secondo luogo viene condotta un’indagine dei motivi di questa disparità di trattamento nell’interazione tra le pratiche di traduzione e le dinamiche di pubblicazione in atto in Italia. Queste sono state dedotte da alcune interviste campione con professionisti dei due campi. I risultati hanno evidenziato una combinazione di fattori casuali e causali, nella quale l’incontro personale e a volte fortuito tra un poeta e un traduttore mette in moto strategie di selezione e di traduzione motivate da ragioni estetiche e a volte ideologiche.

    Various changes in the sociopolitical milieu of Italy led to the increasing tolerance of the study of cadavers in the late Middle Ages. The efforts of Mondino de Liuzzi (1276-1326) and Guido da Vigevano (1280-1349) led to an explosion of cadaver-centric studies in centers such as Bologna, Florence, and Padua during the Renaissance period. Legendary scientists from this era, including Leonardo Da Vinci, Andreas Vesalius, Bartolomeo Eustachio, and Costanzo Varolio, furthered the study of neuroanatomy. The various texts produced during this period not only helped increase the understanding of neuroanatomy and neurophysiology but also led to the formalization of medical education. With increased understanding came new techniques to address various neurosurgical problems from skull fractures to severed peripheral nerves. The present study aims to review the major developments in Italy during the vibrant Renaissance period that led to major progress in the field of neurosurgery.

    This discussion of Italy focuses on the following: cities and regions; population growth; households and families; housing and construction; ethnicity and religion; education; economy and labor force; consumption; and transport and communications. Italy, with its total area of 116,374 square miles, is about the size of Florida and Georgia combined. Its 56.6 million people form the 2nd largest population in Western Europe, after West Germany, but slightly larger than Great Britain and France. The main administrative divisions are 20 regions, subdivided into 95 provinces. The provinces in turn are divided into 8090 "comuni" or municipalities. The 6 cities with more than 500,000 people are Roma, Milano, Napoli, Torino, Genova, and Palermo. They account for 14% of the population. The 43 cities with between 100,000-500,000 account for another 13%. There are 373 middle-sized communities with between 20,000 and 100,000 people, accounting for 26% of population. Italy has a regional problem. The line separating the regions of Emilia Romagna, Toscana, Umbria, and Lazio from the regions to the south and east is important. The regions north of it hold 62% of the population but are responsible for 73% of the gross national product (GNP) and 78% of the industrial product. The regions to the south are economically much weaker. At the time of the last Italian census on October 25, 1981, the country counted 56.6 million inhabitants. Compared to 33.5 million at the turn of the century, this implies an average annual growth rate of .61%. Between 1900-70, nearly 20 million Italians left their country. Most settled in the US, Argentina, and Brazil. Beginning in the 1960s, a new sort of migration was added as young Italians temporarily left to work in the more prosperous countries of northern Europe. The birthrate, which had declined slowly to 18/1000 during the 1960s, fell more rapidly during the 1970s, to 10.9/1000 in 1981 and 10.3 in 1984. The death rate in Italy has changed little

    The central Mediterranean area comprises some of the most active volcanoes of the northern hemisphere. Some of their names recall myths or events in human history: Somma-Vesuvius, Etna, Stromboli, Vulcano, Ischia and Campi Flegrei. These volcanoes are still active today, and produce both effusive and explosive eruptions. In particular, explosive eruptions can produce and disperse large amount of volcanic ash, which pose a threat to environment, economy and human health over a large part of the Mediterranean area. We present and discuss data of ash dispersal from some explosive eruptions of southern Italy volcanoes, which dispersed centimetre -thick ash blankets hundred of kilometres from the source, irrespective of the more limited dispersal of the respective coarse grained fallout and PDC deposits. The collected data also highlight the major role played by lower atmosphere winds in dispersal of ash from weak plumes and ash clouds that accompany PDC emplacement.

    We report evidences of active seabed doming and gas discharge few kilometers offshore from the Naples harbor (Italy). Pockmarks, mounds, and craters characterize the seabed. These morphologies represent the top of shallow crustal structures including pagodas, faults and folds affecting the present-day seabed. They record upraise, pressurization, and release of He and CO2 from mantle melts and decarbonation reactions of crustal rocks. These gases are likely similar to those that feed the hydrothermal systems of the Ischia, Campi Flegrei and Somma-Vesuvius active volcanoes, suggesting the occurrence of a mantle source variously mixed to crustal fluids beneath the Gulf of Naples. The seafloor swelling and breaching by gas upraising and pressurization processes require overpressures in the order of 2–3 MPa. Seabed doming, faulting, and gas discharge are manifestations of non-volcanic unrests potentially preluding submarine eruptions and/or hydrothermal explosions.

    Coda Q for Etna volcano is frequency dependent and the Q frequency pattern and the numerical values ranging from about 100 at 1 Hz to about 300 at 18 Hz are similar to the values obtained for other volcanoes: Campi Flegrei, Aeolian Islands and Hawaii. Moreover the frequency pattern and the numerical values of coda quality factor, for most of the seismically active zones of Italy are very different from those of the volcanic zones. Several studies of the location of magma chambers show the presence of magma pockets beneath Lipari and Vulcano Islands of the Aeolian archipelago and an anomalous low velocity body beneath Etna. These evidences suggest that a possible interpretation of the characteristic frequency pattern of Q on volcanic areas is that the presence of magma can modify the scattering environment and consequently the coda Q estimates.

  11. Pharmacovigilance in Italy: An overview

    2013-01-01

    Full Text Available Introduction: Spontaneous reporting of adverse drug reactions (ADRs is the basis of pharmacovigilance. In fact, ADRs are associated with a high degree of morbidity and mortality. However, underreporting by all healthcare professionals remains the major problem in Italy and in the rest of the world. The dissemination of pharmacovigilance knowledge among Italian healthcare professionals, and the new pharmacovigilance regulations may promote the early detection and reporting of ADRs. This review examines the legislative framework concerning the pharmacovigilance in Italy. Materials and Methods: The information was collected from scientific articles and the websites of the Italian Ministry of Health and the Italian Medicines Agency (Agenzia Italiana del Farmaco, AIFA. Results: The pharmacovigilance system, both in Italy and Europe, has undergone profound changes. European legislation on pharmacovigilance has been changed in 2010 according to the EU Regulation 1235/2010 and Directive 2010/84/EU. Basically, the changes tend to increase the efficiency, speed and transparency of pharmacovigilance activities. The new Regulation (1235/2010 and the Directive (2010/84/EU aim to strengthen the system of pharmacovigilance, establish more precisely who is obliged to do what, and allow faster and easier circulation and retrieval of information about ADRs. Conclusion: A greater knowledge on what is the Italian pharmacovigilance legislation will be useful to improve the status of ADRs reporting and spread the culture of spontaneous reporting.

    The author recalls goals and deadlines of the Europena Community Habitats Directive 94/43/EEC and of the Natura 2000 Network. After saying that Italy has up to now only marginally took part in the definition of habitats and species to be included in the Annexes I, II, II e IV of the Habitat Directive, he underlines that only the collaboration between the Italian Botanical Society and the Italian Ministry of Environment – Nature Conservation Services, has allowed Italy to fill the gap with other countries. Furthermore, he relates the ongoing progress of Natura 2000 in Italy (Bioitaly: about 2700 sites collected, a useful collaboration between botanists, zoologists and ecologists, the constitution of a list of new habitats and species to be included into the Annexes of the Directive. Finally, he wishes a closer working relationship among phytosociologists, botanists and ecologists, in order to avoid the risk of replacing in the CORINE project the phytosociological approach with a less satisfactory physiognomic classification.

    Risk perception is a fundamental element in the definition and the adoption of preventive counter-measures. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. This paper presents results of a survey on seismic risk perception in Italy conducted from January 2013 to present . The research design combines a psychometric and a cultural theoretic approach. More than 7,000 on-line tests have been compiled. The data collected show that in Italy seismic risk perception is strongly underestimated; 86 on 100 Italian citizens, living in the most dangerous zone (namely Zone 1), do not have a correct perception of seismic hazard. From these observations we deem that extremely urgent measures are required in Italy to reach an effective way to communicate seismic risk. Finally, the research presents a comparison between groups on seismic risk perception: a group involved in campaigns of information and education on seismic risk and a control group.

    Full Text Available Il criterio della densità di energia di deformazione (SED considera un preciso volume di controllo posizionato in corrispondenza del piede o della radice dei cordoni di saldatura, ossia delle zone di possibileinnesco delle cricche di fatica. Modellati i cordoni come intagli a V non raccordati e con diverso angolo di apertura, il volume è riconducibile a un settore circolare nei casi di tensione o deformazione piana, e il raggio vale circa 0.3 mm per i giunti saldati in acciaio strutturale.Il valore medio della densità di energia di deformazione dipende essenzialmente dalle distribuzioni singolari nei giunti di medio ed elevato spessore, mentre importante diventa il contributo della T-stress nei giunti di spessore ridotto. Entrambi gli effetti sono correttamente computati utilizzando modelli agli elementi finiti, anche utilizzando mesh con un numero ridotto di gradi di libertà. Il fatto è di notevole interesse per una possibile applicazione del metodo a strutture saldate di geometria complessa. Agli effetti descritti, tipicamente riconducibili a una modellazione piana, si possono accompagnare campi singolari non convenzionali, legati aeffetti tridimensionali indotti dalla geometria. L’effetto out-of-plane è qui evidenziato in relazione ai giunti a semplice sovrapposizione.

  15. Towards a detailed distal tephrostratigraphy in the Central Mediterranean: The last 20,000 yrs record of Lago Grande di Monticchio

    2008-10-01

    A detailed compilation of distal tephrostratigraphy comprising the last 20,000 yrs is given for the Central Mediterranean region. A total of 47 distinct ash layers identified in the maar lake sediments of Lago Grande di Monticchio (Basilicata, Southern Italy) are compared with proximal and distal terrestrial-marine tephra deposits in the circum-central Mediterranean region. The results of these studies provide valuable information for reconstructing the Late Pleistocene and the Holocene dispersal of pyroclastic deposits from south Italian explosive volcanoes, in particular Somma-Vesuvius, the Campi Flegrei caldera, Ischia Island and Mount Etna. Prominent tephras are discussed with respect to their reliability as dating and correlation tools in sedimentary records. Ashes from Plinian eruptions of Somma-Vesuvius (i.e. Avellino, Mercato, Greenish, Pomici di Base), for instance, are well-defined by their distribution patterns and their unique composition. The widespread Y-1 tephra from Mount Etna, on the other hand, derived most likely from two distinct Plinian events with changing wind conditions, and therefore becomes a less reliable stratigraphic marker. Statistical-numerical calculations are presented in order to discriminate between Holocene tephras from the Campi Flegrei caldera (i.e. Astroni 1-3, Agnano Monte Spina, Averno 1, Lagno Amendolare), since these ashes are characterized by an almost indistinguishable chemical fingerprint. As a highlight, numerous Campanian eruptions of proposed low-intensity have been identified in the distal site of Monticchio suggesting a revision of existing tephra dispersal maps and re-calculation of eruptive conditions. In summary, the tephra record of Monticchio is one of the key successions for linking both, terrestrial records from Central-southern Italy and marine sequences from the Tyrrhenian, Adriatic and Ionian Seas.

    Imagine if you could see the River Styx, bathe in the Fountain of Youth, collect water which enhances fertility, wear a gem that heals bodily ailments, understand how our health is affected by geomagnetic fields, venture close to the flames of Hell on Earth and much, much, more. Know something? These things exist - on Earth - today - in Italy and you can visit them because Italy is an open air museum. Ann C. Pizzorusso, in her recent book, reveals how Italy's geology has affected its art, literature, architecture, religion, medicine and just about everything else. She explores the geologic birth of the land, describing the formation of the Alps and Apennines, romantic bays of Tuscany and Lazio, volcanoes of the south and Caribbean-like beaches of Puglia. But that's not all, from the first pages of this visually stunning book, the reader has the impression of being in an art museum, where one can wander from page to page to satisfy one's curiosity-- guided from time to time by the Etruscan priests, Virgil, Dante, Goethe or Leonardo da Vinci himself. Pizzorusso stitches together widely diverse topics - such as gemology, folk remedies, grottoes, painting, literature, physics and religion - using geology as a thread. Quoting everyone from Pliny the Elder to NASA physicist Friedemann Freund, the work is solidly backed scholarship that reads as easily as a summer novel. Wonderfully illustrated with many photos licensed from Italian museums, HRH Elizabeth II and the Ministero Beni Culturali the book highlights the best works in Italian museums and those outside in the "open air museums." This approach can be used in any other country in the world and can be used for cultural tourism (a tour following the book has been organized for cultural and university groups), an ideal way of linking museums to the surrounding landscape.

    The geothermal research in Campania region (Italy), started since the 1930, and continued until the '80 by the SAFEN, ENEL and AGIP companies. Such exploration activity highlighted that most of the volcanic districts of the Campania Region have a very high geothermal gradient and heat flow. In particular, inside the Campi Flegrei caldera and at Ischia island the geothermal gradient measured inside the deep wells reaches temperatures above 100° C between few tens and few hundreds of metres of depth, while the heat flow varies between 120-160 mWm-2 at Agnano and Mofete (Campi Flegrei main drill sites) to more than 500 mWm-2 at Ischia island (south-western sector). A general review of the available literature data (temperature at depth, stratigraphic sections, logs etc.) of the deep wells (down to 3 km b.s.l.) allowed us to quantify the geothermal potential (thermal and electric) of such district. The geothermal potential is about 6 GWy for the Campi Flegrei (Mofete and S. Vito sectors) and 11 GWy for the Ischia island (south-western sector) showing a geothermal reservoir with water and vapour dominant respectively. This results in strong potential interest for economic exploitation of the geothermal resource, both in the range of low-medium enthalpy at few hundreds of meters depth and of high enthalpy at depths of 1-2 km. In this study we try to model the effectiveness of new technologies of boreholes heat exchangers, which would allow to avoid fluid withdrawal, then strongly decreasing the environmental impact. The proposed technology consists of a double-pipe placed in a borehole heat exchange that can work coupled with an ORC. The two pipes, one inside the other, are located in the well in order to transfer the thermal energy to the working fluid during the descent in the external pipe and then go back through the internal pipe properly isolated. We propose a complete design of the borehole heat exchangers. The design activity is performed on a theoretical basis

A total of eleven tephra and cryptotephra layers (PT0915-1 to PT0915-11 were identified, using XRF scanning, magnetic susceptibility measurements, and macro- and microscopic inspection of the sediments. The major element composition of glass shards and/or micro-pumice fragments indicates that the tephras and cryptotephras originate from the explosive volcanism of Italy. Eight tephra and cryptotephra layers were correlated with specific volcanic eruptions: the AD 512 eruption of Somma-Vesuvius (1438 cal yr BP, the Mercato eruption of Somma-Vesuvius (8890 ± 90 cal yr BP, the Tufi Biancastri/LN1-LN2 eruption of the Campi Flegrei (14 749 ± 523 cal yr BP and 15 551 ± 621 cal yr BP, the SMP1-e/Y-3 eruption of the Campi Flegrei (30 000–31 000 cal yr BP, the Campanian Ignimbrite/Y-5 eruption of the Campi Flegrei (39 280 ± 110 cal yr BP, the SMP1-a event of Ischia Island (around 44 000 cal yr BP and the Green Tuff/Y-6 eruption of Pantelleria Island (around 45 000 cal yr BP. One tephra could be attributed to the volcanic activity of Mount Etna, but probably represents an unknown eruption at ca. 60 000 cal yr BP. Cryptotephras PT0915-6 and PT0915-10 remain unclassified so far, but according to the presented age-depth model these would have been deposited around 35 000 and 48 500 cal yr BP, respectively. Some of the tephras and cryptotephras are recognised for the first time in the Balkan region. The tephrostratigraphic work provides important information about ash dispersal and explosion patterns of source volcanoes and can be used to correlate and date geographically distant paleoenvironmental and archaeological archives in the central Mediterranean region.

    A detailed tephrostratigraphic record, which dates back to Marine Isotope Stage (MIS) 5b (ca. 91 kyr), has been established from a 17.76 m long core (Co1215) from Lake Prespa (Macedonia, Albania and Greece). A total of eleven tephra and cryptotephra layers (PT0915-1 to PT0915-11) were identified, using XRF scanning, magnetic susceptibility measurements, and macro- and microscopic inspection of the sediments. The major element composition of glass shards and/or micro-pumice fragments indicates that the tephras and cryptotephras originate from the explosive volcanism of Italy. Eight tephra and cryptotephra layers were correlated with specific volcanic eruptions: the AD 512 eruption of Somma-Vesuvius (1438 cal yr BP), the Mercato eruption of Somma-Vesuvius (8890 ± 90 cal yr BP), the Tufi Biancastri/LN1-LN2 eruption of the Campi Flegrei (14 749 ± 523 cal yr BP and 15 551 ± 621 cal yr BP), the SMP1-e/Y-3 eruption of the Campi Flegrei (30 000-31 000 cal yr BP), the Campanian Ignimbrite/Y-5 eruption of the Campi Flegrei (39 280 ± 110 cal yr BP), the SMP1-a event of Ischia Island (around 44 000 cal yr BP) and the Green Tuff/Y-6 eruption of Pantelleria Island (around 45 000 cal yr BP). One tephra could be attributed to the volcanic activity of Mount Etna, but probably represents an unknown eruption at ca. 60 000 cal yr BP. Cryptotephras PT0915-6 and PT0915-10 remain unclassified so far, but according to the presented age-depth model these would have been deposited around 35 000 and 48 500 cal yr BP, respectively. Some of the tephras and cryptotephras are recognised for the first time in the Balkan region. The tephrostratigraphic work provides important information about ash dispersal and explosion patterns of source volcanoes and can be used to correlate and date geographically distant paleoenvironmental and archaeological archives in the central Mediterranean region.

    The CERN Accelerator School’s introductory course is a great success. This year the CERN Accelerator School held its "Introduction to Accelerator Physics" course in Frascati, Italy, from 2-14 November in collaboration with the University of Rome "La Sapienza" and the INFN Frascati National Laboratory. The Introductory level course is particularly important since, for the majority of participants, it is the first opportunity to discover the various aspects of accelerator physics. For this school the programme had been significantly revised in order to take into account the new trends currently being developed in the field, thus putting more emphasis on linacs, synchrotron light sources and free-electron lasers. The school was a resounding success with 115 participants of more than 23 nationalities. Feedback from the students praised the expertise of the lecturers, the high standard of the lectures as well as the excellent organizati...

    Robotic surgery in Italy has become a clinical reality that is gaining increasing acceptance. As of 2011 after the United States, Italy together with Germany is the country with the largest number of active Robotic centers, 46, and da Vinci Robots installed, with at least 116 operators already trained. The number of interventions performed in Italy in 2011 exceeded 6,000 and in 2010 were 4,784, with prevalence for urology, general surgery and gynecology, however these interventions have also begun to be applied in other fields such as cervicofacial, cardiothoracic and pediatric surgery. In Italy Robotic centers are mostly located in Northern Italy, while in the South there are only a few centers, and four regions are lacking altogether. Of the 46 centers which were started in 1999, the vast majority is still operational and almost half handle over 200 cases a year. The quality of the work is also especially high with large diffusion of radical prostatectomy in urology and liver resection and colic in general surgery. The method is very well accepted among operators, over 80 %, and among patients, over 95 %. From the analysis of world literature and a survey carried out in Italy, Robotic surgery, which at the moment could be better defined as telesurgery, represents a significant advantage for operators and a consistent gain for the patient. However, it still has important limits such as high cost and non-structured training of operators.

    The contribution focuses on the current status of the ESA study entitled "INSARAP: Sentinel-1 InSAR Performance study with TOPS Data". The study investigates the performance of the interferometric wide swath (IW) mode of Sentinel-1, which is implemented using the terrain observation by progressive scans (TOPS) mode. In this regard, first analyses with Sentinel-1 time series will be shown, with a comparison with in-situ geodetic measurements on different test sites identified in the framework of the study, namely, Campi Flegrei/Vesuvius area in Italy, Istanbul city in Turkey, and Mexico City. The evaluation of the results will be performed by exploiting mainly continuous GPS stations located on the different sites, besides leveling measurements when also available. Also in a recent past, the comparison between InSAR and continuous GPS data, the latter projected into the radar LOS, has proven to be very effective for a cross comparison, besides InSAR Cal/Val activities, as it was for instance in the case of the recent inflation events occurred in Campi Flegrei area, marked by the well know bradyseismic phenomenon. Although continuous GPS networks are characterized by a poor space coverage in comparison with InSAR results, continuous GPS data recording allows to complement the geodetic information from InSAR sensors, limited by their revisiting time. The issue to be faced in this study is the possibility to deal with very low deformation rates in comparison with the Sentinel-1 C-band data, although the Sentinel-1 time series we expect to get from October 2014 to date should allow the identification of ground deformation in the areas of interest.

    Time-dependent gravimetric measurements can detect subsurface processes long before magma flow leads to earthquakes or other eruption precursors. The ability of gravity measurements to detect subsurface mass flow is greatly enhanced if gravity measurements are analyzed and modeled with ground-deformation data. Obtaining the maximum information from microgravity studies requires careful evaluation of the layout of network benchmarks, the gravity environmental signal, and the coupling between gravity changes and crustal deformation. When changes in the system under study are fast (hours to weeks), as in hydrothermal systems and restless volcanoes, continuous gravity observations at selected sites can help to capture many details of the dynamics of the intrusive sources. Despite the instrumental effects, mainly caused by atmospheric temperature, results from monitoring at Mt. Etna volcano show that continuous measurements are a powerful tool for monitoring and studying volcanoes.Several analytical and numerical mathematical models can beused to fit gravity and deformation data. Analytical models offer a closed-form description of the volcanic source. In principle, this allows one to readily infer the relative importance of the source parameters. In active volcanic sites such as Long Valley caldera (California, U.S.A.) and Campi Flegrei (Italy), careful use of analytical models and high-quality data sets has produced good results. However, the simplifications that make analytical models tractable might result in misleading volcanological inter-pretations, particularly when the real crust surrounding the source is far from the homogeneous/ isotropic assumption. Using numerical models allows consideration of more realistic descriptions of the sources and of the crust where they are located (e.g., vertical and lateral mechanical discontinuities, complex source geometries, and topography). Applications at Teide volcano (Tenerife) and Campi Flegrei demonstrate the

  9. Health workforce governance in Italy.

    2015-12-01

    More precise health workforce governance has become a prominent issue in healthcare systems. This issue is particularly important in Italy, given its strongly doctor-centered healthcare system and the dramatic aging of its physicians' labor force. Using different sources of information (statistical data, official planning documents and interviews with key informants), the article attempts to answer two questions. Why has the Italian healthcare systems found itself in the situation of a potential drastic reduction in the amount of doctors in the medium term without a rebalancing through a different mix of skills and professionals? How good is the capacity of the Italian healthcare system to plan healthcare workforce needs? The widespread presence of 'older' physicians is the result of the strong entry of doctors into the Italian healthcare system in the 1970s and 1980s. Institutional fragmentation, difficulties in drafting broad healthcare reforms, political instability and austerity measures explain why Italian health workforce forecasting and planning are still unsatisfactory, although recent developments indicate that changes are under way. In order to tackle these problems it is necessary to foster closer cooperation among a wide range of stakeholders, to move from uni-professional to multi-professional health workforce planning, and to partially re-centralise decision making.

    To understand uplift phenomenon occurred during the April 2012 - January 2013 time interval at Campi Flegrei caldera, we exploited the displacement time series obtained by processing 90 SAR images acquired from the COSMO-SkyMed sensor constellation along ascending orbits via the well-known DInSAR algorithm referred to as SBAS algorithm, and the measurements provided by 14 continuous GPS stations deployed within the caldera and belonging to the permanent INGV-OV monitoring network. In particular, the caldera has shown a rapid uplift of about 6 cm with a peak rate of about 3 cm/month in December 2012. This event led the Italian Civil Protection to raise the alert level of the volcano from green to yellow. Using a novel geodetic inversion technique we imaged the kinematics of the intrusion of a magmatic sill beneath the town of Pozzuoli at a depth of about 3100 m. The retrieved kinematics was then used as input to infer the dynamics of the sill intrusion using a recently developed numerical model. The best fit obtained by non-linear inverse approach that consider a time-varying deformation field is a penny-shaped source located at a depth of 3100 m. To study the detail of the intrusion process we have applied a geodetic imaging technique to determine the spatial and temporal kinematics of the ground deformation source in the selected period. The retrieved temporal pattern of the source geometry reflects that of a growing sill that, at the end of the considered period, has a roughly elliptical geometry with an extension of about 6 km in the EW direction and about 4 km in the NS one. The maximum aperture of the sill is of about 30 cm at its center. To understand the dynamics of this phenomenon we used a numerical model of the emplacement of a magmatic sill, to fit the retrieved geometry. The parameters to be determined are: the average magma viscosity, the amount of magma already present in the sill before the 2012-2013 episode and the magma injection rate. Results show

    Full Text Available Abstract Background There has been a noticeable annual increase in the number of children coming to Italy for medical treatment, just like it has happened in the rest of the European Union. In Italy, the assistance to children suffering from cancer is assured by the current network of 54 centres members of the Italian Association of Paediatric Haematology and Oncology (AIEOP, which has kept records of all demographic and clinical data in the database of Mod.1.01 Registry since 1989. Methods We used the information stored in the already mentioned database to assess the impact of immigration of foreign children with cancer on centres' activity, with the scope of drawing a map of the assistance to these cases. Results Out of 14,738 cases recorded by all centres in the period from 1999 to 2008, 92.2% were born and resident in Italy, 4.1% (608 were born abroad and living abroad and 3.7% (538 were born abroad and living in Italy. Foreign children cases have increased over the years from 2.5% in 1999 to. 8.1% in 2008. Most immigrant children came from Europe (65.7%, whereas patients who came from America, Asia and Oceania amounted to 13.2%, 10.1%, 0.2%, respectively. The immigrant survival rate was lower compared to that of children who were born in Italy. This is especially true for acute lymphoblastic leukaemia patients entered an AIEOP protocol, who showed a 10-years survival rate of 71.0% vs. 80.7% (p Conclusions Children and adolescents are an increasingly important part of the immigration phenomenon, which occurs in many parts of the world. In Italy the vast majority of children affected by malignancies are treated in AIEOP centres. Since immigrant children are predominantly treated in northern Italy, these centres have developed a special expertise in treating immigrant patients, which is certainly very useful for the entire AIEOP network.

    Pollen-related allergies are very common in Italy and pollinosis is the commonest allergic disease. The type of allergenic plants and the prevalence of hay fever varies among regions. In the Mediterranean area there are characteristic climatic conditions (mildness of winter, summer dryness) that facilitate the growth of a typical vegetation with its associated various types of allergenic pollen grains, some of them very different from those of central and northern Europe. Italy has a central position in the Mediterranean basin, but because of its geographic characteristics, there are different climatic aspects with different vegetation between northern, central, and southern areas. Gramineae are the most common allergenic plants in northern and central Italy, where more than 60% of patients with pollinosis are grass-pollen sensitive. Parietaria is the most important pollinating plant in southern Italy and Liguria. Olea europaea, the olive tree with cultivation widespread in the whole Mediterranean basin, is responsible for frequently severe pollinosis, particularly in some regions of the southern Italy.

    This study reviews a series of 811 malignant pleural mesothelioma cases, diagnosed at hospitals in Trieste and Monfalcone districts of north eastern Italy, a narrow coastal strip with a population of about three lakh, in the period 1968-2008. The diagnosis was based on histological examination in 801 cases, and cytological findings in 10. Necropsy was performed in 610 cases. Occupational histories were obtained directly from the patients or their relatives through personal or telephone interviews. Routine lung sections were examined for asbestos bodies in 500 cases. In 143 cases asbestos bodies were isolated and counted by chemical digestion of the lung tissue using the Smith-Naylor method. The series included 717 men and 94 women aged between 32 and 93 years (mean 69.2 years). Detailed occupational data was obtained for 732 cases.The majority of patients had marine jobs - shipbuilding (449 cases), maritime trades (56 cases), and port activities (39 cases). The nature of work of other patients included a variety of occupations, with non-shipbuilding industries being the most common. Thirty-four women cleaned the work clothes of family members occupationally exposed and hence had a history of asbestos exposure at home. Most of the patients had their first exposure to asbestos before 1960. The latency period ranged between 13 and 73 years (mean 48.2). Latency period among insulators and dock workers were shorter than other categories. Asbestos bodies were detected on routine lung sections in 343 cases (68.6%). Lung asbestos body burdens after isolation ranged between two to 10 millions bodies per gram of dried tissue. Despite some limitations in the use of asbestos in this area since the 1970s, the incidence of tumor remained high during the last years.

    2013-01-01

    Full Text Available Italian dialects occupy an important position in the history of Italian linguistics and are still present and relevant in the linguistic panorama of modern Italy. The purpose of this article is to outline the linguistic image of Italy by drawing attention to its dialects. Through analysis of the situation after unification in Italy in 1861, the author attempts to mark off functions and roles which dialects used to serve. In the second part of the article she concentrates on the phenomena of nuova dialettalità, or the new perspective and collocation of dialect in the Italian linguistic panorama of the 21st century. This article is a part of a research project dedicated to functions and uses of dialects in the Italian cinematography.

    Objective. Evaluate the ecological relationship between skin melanoma epidemiology and latitude in Italy. Methods. We used data from the Italian network of cancer registries (Airtum). In a Poisson model, we evaluated the effect on incidence, mortality, and survival of latitude, adjusting for some demographic, social, phenotypic, and behavioural variables. Results. Incidence increased in Italy by 17% for each degree of increase in latitude. The effect of latitude was statistically significantly present also adjusting for other variables (incidence rate ratio = 1.08). The effect of latitude on increasing mortality (mortality rate ratio = 1.27) and improving survival (relative excess risk of death = 0.93) was no longer present in the multivariate model. Conclusion. Melanoma incidence, mortality, and survival vary in Italy according to latitude. After adjustment for several confounders, incidence still grows with growing latitude. Presumably, latitude expresses other variables that might be related to individual susceptibility and/or local care.

O trabalho sustenta que é a Parceria Público-Privado que conecta estas iniciativas e que, por isso, é possível captar um sentido para as mudanças esperadas na universidade pública brasileira. A investigação analisa os pressupostos e as conseqüências prováveis do Projeto de Parceria Público-Privado, discute as suas expressões na educação superior - o PROUNI e a Inovação -, concluindo que estas movimentações estabelecem que o veio axial da expansão da educação superior se dará por meio do fornecimento privado subsidiado por verbas públicas, opção que reduz o número de novas matrículas. As parcerias público-privado (Inovação e PROUNI redefinem as instituições públicas, contribuindo para o apagamento da fronteira moderna entre o público e o privado, convertendo a educação em mercadoria e a universidade em lugar de capitalismo acadêmico.

It advocates that it is the Public-Private Partnership that connects these initiatives, and thus allows us to encounter a meaning for the expected changes in the Brazilian public universities. The text then analyzes the conjectures and probable consequences of the Public-Private Partnership Project, and discusses their expressions in higher education - PROUNI and Inovação - to conclude that these movements show that the main thrust of the higher education expansion will be a private supply subsidized by public resources, an option that reduces the number of new enrollments. The Public-Private Partnership (Inovação and PROUNI redefines public institutions and contributes to erasing the modern border between public and private, converting education into a commodity and universities into a place of academic capitalism. With the erosion of the concept of public space as a place of knowledge production, criticism will suffer severe restrictions, which will bring the problem of academic freedom again.

    Background: The European Community recommends mammography, cervical and colorectal cancer screening programmes. In Italy, cancer screening programmes have been included in the Basic Healthcare Parameters (Livelli Essenziali di Assistenza since 2001. Full national coverage of a population-based organized screening programme has been planned for in Italy and is being implemented. Since 2005, the Ministry of Health - Department of Prevention has formally charged The National Centre for Screening Monitoring (Osservatorio Nazionale Screening –ONS- with monitoring and promoting screening programmes nationwide. Participation of target populations is a key indicator of the impact and efficacy of a screening programme in reducing cancer mortality.

    Methods: Attendance of invitees is one of the indicators calculated every year in the quality control of Italian screening programmes. Data collection is organized by means of a structured questionnaire, sent by ONS to the referent for data collection in each Region, who then returns the completed questionnaires to the Regional Centre. Questionnaires are then sent to the National Centre. Logical and epidemiologic checks are performed at both levels. Every year ONS publishes reports on the results of the surveys. A feasibility study for a National data warehouse based on individual records is in progress. The national survey “Multiscopo sulle famiglie” and the Passi Study (Progetti delle Aziende Sanitarie per la Salute in Italia provided additional information regarding spontaneous preventive health care activities in the Italian population.

    Results: Mammography screening: In 2006, 78.2% of Italian women aged 50-69 lived in areas where organised screening was in place (theoretical extension, however, the distribution of the screening activity is not uniform (higher in Northern/Central Italy compared with Southern

    Socioeconomic inequality and its impact on health is a growing concern in the European public health debate. In many countries, the issue is moving away from description towards the identification of the determinants of inequalities and the development of policies explicitly aimed at reducing inequalities in health. In Italy, ten years after the publication of the first report on inequalities in health, this topic is seldom present on the agenda of public policy makers. The purpose of this report is to update the Italian profile of social variation in health and health care in order to stimulate the debate on ways to tackle inequalities in health that are preventable. In the first section of this book, the threefold objective is to describe the principal mechanisms involved in the generation of social inequalities in health (Introduction); to report Italian data on the distribution and magnitude of this phenomenon in the last decade; and to evaluate policies and interventions in both the social (chapter 1.9, Section I) and the health sector (chapter 2.3, Section I), which are potentially useful to reduce health inequalities. It is intended for anyone who is in a position to contribute t o decision-making that will benefit the health of communities. For this reason, chapters are organized by specific determinants of inequalities on which interentions may have an impact. The methodological approach in the second section focuses on the best methods to monitor social inequalities including recommendations on social indicators, sources of information and study models, based on European guidelines revised for the Italian situation. According to data from national and local studies, mortality increases linearly with social disadvantage for a wide range of indicators at both the individual (education, social class, income, quality of housing) and the geographical level (deprivation indexes computed at different levels of aggregation). This positive correlation is evident

    Biomass is considered a potential fuel and a renewable source for the future. In Italy, the utilization of biomass nowadays is addressed, above all, towards thermal energy production. In the near future, however, it is predictable a higher differentiation in order to use biomass with the more suitable technology. In this paper we review the utilization of residual biomasses.

    2010-03-01

    Full Text Available We assessed societal landslide and flood risk to the population of Italy. The assessment was conducted at the national (synoptic and at the regional scales. For the assessment, we used an improved version of the catalogue of historical landslide and flood events that have resulted in loss of life, missing persons, injuries and homelessness in Italy, from 1850 to 2008. This is the recent portion of a larger catalogue spanning the 1941-year period from 68 to 2008. We started by discussing uncertainty and completeness in the historical catalogue, and we performed an analysis of the temporal and geographical pattern of harmful landslide and flood events, in Italy. We found that sites affected by harmful landslides or floods are not distributed evenly in Italy, and we attributed the differences to different physiographical settings. To determine societal risk, we investigated the distribution of the number of landslide and flood casualties (deaths, missing persons, and injured people in Italy, and in the 20 Italian Regions. Using order statistics, we found that the intensity of a landslide or flood event – measured by the total number of casualties in the event – follows a general negative power law trend. Next, we modelled the empirical distributions of the frequency of landslide and flood events with casualties in Italy and in each Region using a Zipf distribution. We used the scaling exponent s of the probability mass function (PMF of the intensity of the events, which controls the proportion of small, medium, and large events, to compare societal risk levels in different geographical areas and for different periods. Lastly, to consider the frequency of the events with casualties, we scaled the PMF obtained for the individual Regions to the total number of events in each Region, in the period 1950–2008, and we used the results to rank societal landslide and flood risk in Italy. We found that in the considered period societal landslide

  17. Induced abortion and contraception in Italy.

    Science.gov (United States)

    Spinelli, A; Grandolfo, M E

    1991-09-01

    This article discusses the legal and epidemiologic status of abortion in Italy, and its relationship to fertility and contraception. Enacted in May 1978, Italy's abortion law allows the operation to be performed during the 1st 90 days of gestation for a broad range of health, social, and psychological reasons. Women under 18 must receive written permission from a parent, guardian, or judge in order to undergo an abortion. The operation is free of charge. Health workers who object to abortion because of religious or moral reasons are exempt from participating. Regional differences exist concerning the availability of abortion, easy to procure in some places and difficult to obtain in others. After an initial increase following legalization, the abortion rate was 13.5/1000 women aged 15-44 and the abortion ratio was 309/1000 live births -- an intermediate rate and ratio compared to other countries. By the time the Abortion Act of 1978 was adopted, Italy already had one of the lowest fertility levels in Europe. Thus, the legalization of abortion has had no impact on fertility trends. Contrary to initial fears that the legalization of abortion would make abortion a method of family planning, 80% of the women who sought an abortion in 1983-88 were using birth control at the time (withdrawal being the most common method used by this group). In fact, most women who undergo abortions are married, between the ages of 25-34, and with at least one child. Evidence indicates widespread ignorance concerning reproduction. In a 1989 survey, only 65% of women could identify the fertile period of the menstrual cycle. Italy has no sex education in schools or national family planning programs. Compared to most of Europe, Italy still has low levels of reliable contraceptive usage. This points to the need to guarantee the availability of abortion.

  18. Is marriage loosing its centrality in Italy?

    Directory of Open Access Journals (Sweden)

    2004-09-01

    Full Text Available Unlike the countries of north-western Europe, marriage in Italy has maintained a crucial role in the process of family formation. This raise doubts about the possibility that the theory of "second demographic transition" could adequately account for the behaviour of the European population living south of the Alps. The aim of this paper is twofold: to provide some empirical evidence that cohabitation is now spreading in Italy; and to propose an explanation of the delay of its diffusion until the 1990s. The hypothesis proposed here explains the delay, not so much in terms of limited interest of the Italian youth towards this type of union, but with the convenience of the children in the Mediterranean area to avoid choices which are openly clashing with the values of parents.

  19. CERN Neutrinos search for sunshine in Italy!

    CERN Multimedia

    Wednesday, 18th June 2008. The CNGS (CERN Neutrinos to Gran Sasso) beam has re-started, shooting muon neutrinos towards Italy. The neutrino beam should run this year until mid November.The aim of CNGS is to understand the oscillation of neutrinos, for example their transformation from muon into tau neutrinos over long distances.Edda Gschwendtner, the liaison physicist of the CNGS beam, describes the progress of the project, “We did a lot of modifications this year to CNGS, which was a huge amount of work, with many groups and services involved. In parallel the OPERA detector in Italy made an enormous progress in completing their detector and we are looking forward to seeing tau neutrinos soon.”

    A cluster of 22 imported malaria cases, 21 caused by Plasmodium falciparum, was observed among illegal Chinese immigrants in northern Italy in the summer of 2000. The rate of severe disease was high because the patients were not immune and they sought health-care services late in their illness because of their clandestine status. Recognition of the outbreak was delayed because no regional alert system among infectious diseases hospitals was in place.

    2015-05-01

    An investigation was carried out on the distribution and biodiversity of steinernematid and heterorhabdtid entomopathogenic nematodes (EPN) in nine regions of Italy in the period 1990-2010. More than 2000 samples were collected from 580 localities and 133 of them yielded EPN specimens. A mapping of EPN distribution in Italy showed 133 indigenous EPN strains belonging to 12 species: 43 isolates of Heterorhabditis bacteriophora, 1 of H. downesi, 1 of H. megidis, 51 of Steinernema feltiae, 12 of S. affine, 4 of S. kraussei, 8 of S. apuliae, 5 of S. ichnusae, 3 of S. carpocapsae, 1 of S. vulcanicum, 3 of Steinernema 'isolate S.sp.MY7' of 'S. intermedium group' and 1 of S. arenarium. Steinernematids are more widespread than heterorhabditids and S. feltiae and H. bacteriophora are the most commonly encountered species. Sampling sites were grouped into 11 habitats: uncultivated land, orchard, field, sea coast, pinewood, broadleaf wood, grasslands, river and lake borders, caves, salt pan and moist zones; the soil texture of each site was defined and the preferences of habitat and soil texture of each species was assessed. Except for the two dominant species, S. feltiae and H. bacteriophora, EPN occurrence tends to be correlated with a specific vegetation habitat. Steinernema kraussei, H. downesi and H. megidis were collected only in Sicily and three of the species recently described - S. apuliae, S. ichnusae and S. vulcanicum - are known only from Italy and seem to be endemic.

    2011-01-01

    According to recent data, foreign population currently in Italy is estimated to be 5,3 million, 550,000 irregular. Migration from Eastern Europe has progressively assumed leading position in the Italian panorama, downsizing other origins: betweenn 2005 and 2010, this component passed from 46% to 50,8% of the total immigrants, whereas all the other macro-areas have lost relative importance. Perspectives of slowing down of migration toward Italy could be real only when significant changes would happen in the areas at the origin of migration flow. In fact, if it is true that the demographic surplus from East Europe is bound to decrease through the process of local turnover of work supply, other great regions will show enormous excess of manpower. In North Africa, 3 million new workplaces will yearly be needed just to absorb excess of young workforce; in Latin America, the new workplaces to create will be almost twice as many. The sub Saharan Africa will however be under special observation, with 15-20 million places to create annually to absorb excess of offer. Italy could play as one of the safety valves of emigration.

  5. Chapter 44: history of neurology in Italy.

    Science.gov (United States)

    Bentivoglio, Marina; Mazzarello, Paolo

    2010-01-01

    The chapter starts from the Renaissance (although the origins of Italian neurology can be traced back to the Middle Ages), when treatises of nervous system physiopathology still followed Hippocratic and Galenic "humoral" theories. In Italy, as elsewhere in Europe, the concepts of humoral pathology were abandoned in the 18th century, when neurology was influenced by novel trends. Neurology acquired the status of clinical discipline (as "clinic of mental diseases") after national reunification (declared in 1861 but completed much later). At the end of the 19th and first decades of the 20th century, eminent Italian "neuropsychiatrists" (including, among many others, Ugo Cerletti, who introduced electroconvulsive shock therapy in 1938) stimulated novel knowledge and approaches, "centers of excellence" flourished, and "Neurological Institutes" were founded. In the first half of the 20th century, the history of Italian neurology was dominated by World Wars I and II (which stimulated studies on the wounded) and the fascist regime in-between the Wars (when the flow of information was instead very limited). Italy became a republic in 1946, and modern neurology and its distinction from psychiatry were finally promoted. The chapter also provides detailed accounts of scientific societies and journals dedicated to the neurological sciences in Italy.

  6. Current status of geothermal energy in Italy

    Energy Technology Data Exchange (ETDEWEB)

    Carella, R.

    Italy has been one of the first countries to develop applications or its geothermal energy resources. As a resource it is both abundant and available in the high temperature range. A world premiere was the electricity production in Tuscany (Western Italy) output 56 which at present is 3200 GWh/y from 624 MW of operating capacity. In the low-enthalpy field Italy has enjoyed widespread development of spas, both for therapeutic and heating purposes. The latter's output has now attained presently 127,000 TOE/y. District and other residential heating amount to about 37,000 TOE/y and include two recent very significant projects in the Po Valley (Ferrara and Vicenza). Some large-size greenhouse complexes are heated by geothermal fluids (M. Amiata in Tuscany and Pantani in Latium) as well as fish farms on the Tyrrhenian coast. Agricultural applications account for 19,000 TOE/y. While the outlook is bright for electricity production which is due to increase substantially in the next decade, the short-term future is uncertain for low enthalpy resources, especially in view of low energy prices. Given the abundance of the resources and their environmental benefits, longer term prospects should be good, particularly if energy prices firm up. 1 fig.

    Natural radionuclides and (137)Cs in twenty seven honeys produced in a region of the Central Italy were determined by alpha ((235)U, (238)U, (210)Po, (232)Th and (228)Th) and gamma spectrometry ((137)Cs, (40)K, (226)Ra and (228)Ra). The study was carried out in order to estimate the background levels of natural ((40)K, (238)U and (232)Th and their progeny) and artificial radionuclides ((137)Cs) in various honey samples, as well as to compile a data base for radioactivity levels in that region. (40)K showed a mean activity of 28.1±23.0Bqkg(-1) with a range of 7.28-101Bqkg(-1). The mean of (210)Po activity resulted 0.40±0.46Bqkg(-1) with a range of 0.03-1.98Bqkg(-1). The mean of (238)U activity resulted 0.020±0.010Bqkg(-1). (226)Ra and (228)Ra resulted always Italy. The honeys produced in Central Italy were of good quality in relation to the studied parameters, confirming the general image of a genuine and healthy food associated to this traditional products.

    This report aims to evaluate the italian situation in matter of the nuclear, following the referendum of 1987 which decided to stop the nuclear power plants in the country. The first part is devoted to the historical aspects of the nuclear sector in Italy. The second chapter presents the institutional and legislative framework. The third chapter discusses the today situation and the italian actors of the nuclear, from the radioactive wastes management and the dismantling of nuclear installations to the engineering service realized in other countries. It discusses also the research and development programs. The last chapter proposes perspectives of the debate around a possible restart of the nuclear activity in Italy.

  9. 3D Imaging of Brittle/Ductile transition of the crust beneath the resurgent calderas

    2012-04-01

    Rheology is a crucial factor to understand the mechanical behaviour and evolution of the crust in young and tectonically active belts. The aim of this paper is to investigate the rheological properties of the crust beneath resurgent calderas as Long Valley caldera (California USA) and Campi Flegrei (Southern Italy). Through the rheological proprieties of the calderas area, we highlight the driving process that determine the cut off of the local seismicity [K. Ito, 1993]. In this context, we consider the thermal proprieties and mechanical heterogeneity of the crust in order to develop a 3D conductive time dependent thermal model of the upper crust beneath the two calderas. More specifically we integrate geophysical information (gravimetric, seismic and boreholes data) available for the considered area in FEM environment [Manconi A. et al., 2010]. We performed a numerical solution of Fourier equation to carry out an advance optimization of the real measured data. We produce a set of forward models and propose, in order to analyse and solve the statistical problem, the Monte Carlo optimization procedures as Genetic Algorithm [Manconi A. et al., 2009]. In particular we search for the heat production, the volume source distribution and the surface emissivity parameters that providing the best-fit of the geothermal profiles data measured at boreholes, by solving the non stationary heat flow equation (Campanian Ignimbrite eruption about 40 kyr for Campi Flegrei caldera and Bishop tuff eruption about 700 kyr for Long Valley caldera). The performed thermal fields allow us to obtain the rheological stratification of the crust beneath two resurgent calderas; the models suggest that the uprising of a ductile layer which connects the upper mantle to the volcanic feeding system could determine the stress conditions that controlled the distribution of seismicity. In fact, the computed 3D imaging of Brittle/Ductile transition well agrees with the seismic hypocentral distribution

    Directory of Open Access Journals (Sweden)

    Giovanni Picker

    2012-12-01

    Full Text Available In this article the author focuses on the policies concerning the Roma in Florence, against the background of the recent eruption of exclusionary policy measures targeting Roma in Italy. In the mid-1980s the Tuscan regional council decided to construct urban camps as housing solutions for the Roma fleeing the economic and political dissolution of Yugoslavia. The author draws on the fieldwork he has conducted in Florence in 2007 and 2008, and borrows from Apparudai’s (1996 reflections on the “world of representation” in relation to globalization. He historically dissects the political imagination behind camp policies concerning Roma in Tuscany through the early 2000s. He also shows that in 2007 the fundamental traits of that representation persisted in Florentine civil servants’ views and practices vis-à-vis Roma. In the conclusion, the author defines the policy category “nomadism” as the main “political technology” which has allowed urban segregation of Roma in Florence to persist from the mid-1980s. More generally, the author argues that deploying “nomadism” as policy category was the condition under which over the last thirty years a single governmental system has been crystallizing.

    Although outcropping only rarely in Italy, gypsum karst has been described in detail since the early XXth century (Marinelli, 1917). Gypsum caves are now known from almost all Italian regions (Madonia & Forti, 2003), but are mainly localised along the northern border of the Apennine chain (Emilia Romagna and Marche regions), Calabria, and Sicily, where the major outcrops occur. Recently, important caves have also been discovered in the underground gypsum quarries in Piedmont (Vigna et al., 2010). During the late 80s and 90s several multidisciplinary studies have been carried out in many gypsum areas. All this work converged into a comprehensive overview in 2003 (Madonia & Forti, 2003). Further detailed studies focused on the gypsum areas of Emilia Romagna (Chiesi et al., 2010; Forti & Lucci, 2010; Demaria et al., 2012; De Waele & Pasini, 2013; Ercolani et al., 2013; Columbu et al., 2015; Lucci & Piastra, 2015; Tedeschi et al., 2015) and of Sicily (Madonia & Vattano, 2011). Sinkholes related to Permo-Triassic gypsum have been studied in Friuli Venezia Giulia (Zini et al., 2015). This presentation will review the state of the art regarding different aspects of evaporite karst in Italy focusing on the main new results. References Chiesi M., et al.

    Full Text Available Abstract Background Anthrax has almost disappeared from mainland Europe, except for the Mediterranean region where cases are still reported. In Central and South Italy, anthrax is enzootic, but in the North there are currently no high risk areas, with only sporadic cases having been registered in the last few decades. Regional genetic and molecular characterizations of anthrax in these regions are still lacking. To investigate the potential molecular diversity of Bacillus anthracis in Northern Italy, canonical Single nucleotide polymorphism (canSNP and Multilocus variable number tandem repeat analysis (MLVA genotyping was performed against all isolates from animal outbreaks registered in the last twenty years in the region. Findings Six B. anthracis strains were analyzed. The canSNP analysis indicates the presence of three sublineages/subgroups each of which belong to one of the 12 worldwide CanSNP genotypes: B.Br.CNEVA (3 isolates, A.Br.005/006 (1 isolates and A.008/009 (2 isolate. The latter is the dominant canSNP genotype in Italy. The 15-loci MLVA analysis revealed five different genotypes among the isolates. Conclusions The major B branch and the A.Br.005/006 were recovered in the Northeast region. The genetic structure of anthrax discovered in this area differs from the rest of the country, suggesting the presence of a separate and independent B. anthracis molecular evolution niche. Although the isolates analyzed in this study are limited in quantity and representation, these results indicate that B. anthracis genetic diversity changes around the Alps.

    Full Text Available Canine urinary capillariosis is caused by the nematode Pearsonema plica. P. plica infection is seldomly detected in clinical practice mainly due to diagnostic limitations. This report describes six cases of urinary capillariosis in dogs from Italy. Recurrent cystitis was observed in one dog, whereas another patient was affected by glomerular amyloidosis. In the remaining animals, the infection was considered an incidental finding. Immature eggs of the parasite were observed with urine sediment examination in 3/6 patients. Increased awareness of the potential pathogenic role of P. plica. and clinical disease presentation could help identify infected animals.

  16. Financial innovation and monetary control in Italy

    2013-12-01

    Full Text Available Increasingly the pressures of deregulation and competition have promoted innovation in the development of financial instruments. In the case of Italy the pressure for innovation has arisen from the need to finance the public sector borrowing requirement and the effects of inflation. As a result, funding instruments have been switched from longer-term bonds to the shorter-term treasury bill. However, this can lead to excessive supply of liquid assets with consequent problems for monetary controls. Such factors will make it more difficult to use monetary aggregates as a guide to monetary policy in the future

    2008-06-01

    Full Text Available This paper presents a comprehensive overview of the surface deformation retrieval capability of the Differential Synthetic Aperture Radar Interferometry (DInSAR algorithm, referred to as Small BAseline Subset (SBAS technique, in the context of active volcanic areas. In particular, after a brief description of the algorithm some experiments relevant to three selected case-study areas are presented. First, we concentrate on the application of the SBAS algorithm to a single-orbit scenario, thus considering a set of SAR data composed by images acquired on descending orbits by the European Remote Sensing (ERS radar sensors and relevant to the Long Valley caldera (eastern California area. Subsequently, we address the capability of the SBAS technique in a multipleorbit context by referring to Mt. Etna volcano (southern Italy test site, with respect to which two different ERS data set, composed by images acquired both on ascending and descending orbits, are available. Finally, we take advantage of the capability of the algorithm to work in a multi-platform scenario by jointly exploiting two different sets of SAR images collected by the ERS and the Environment Satellite (ENVISAT radar sensors in the Campi Flegrei caldera (southern Italy area. The presented results demonstrate the effectiveness of the algorithm to investigate the deformation field in active volcanic areas and the potential of the DInSAR methodologies within routine surveillance scenario.

  4. Werner Sombart and his reception in Italy

    Simona Pisanelli

    2015-03-01

    Full Text Available This article intends to focus on the difficulty encountered by Werner Sombart’s works in gaining a hearing in various Italian intellectual circuits. As is well known, Sombart belonged to the German Historical School of economics, sharing with other scholars of that school the same problems in getting his work known in Italy. Our aim is to explain the reason for this hostile reception. First of all, we will analyze the factors which generally hindered the spread of the German Historical School in Italy, recognizing in economists like Francesco Ferrara, Idealists like Benedetto Croce and Marxists like Antonio Labriola some of its strongest opponents. We will dwell on the cases of Gustav Schmoller and Max Weber, in order to give two representative examples of the slow and complicated Italian reception of methodological approaches and analytical perspectives which characterized the scientific experience of the German Historical School. Secondly, we will try to show why Sombart was even less appreciated than other German social scientists, giving the reasons that attracted severe criticism from economists, economic historians and sociologists towards his interdisciplinary approach in the analysis of modern capitalism. Finally, we will show the reasons of the contemporary rediscovery of Sombart and of his works.

    Workplace drug testing (WDT) was established in Italy on 30 October 2007. Two tiers of survey are required: the first tier concerns drug testing on urine samples, the second involves both urine and hair analysis. Between July 2008 and December 2011, 10 598 workers' urine samples and 72 hair samples for opiates, cocaine, cannabinoids, amphetamines, methylenedioxyamphetamines, methadone, and buprenorphine were tested in our laboratory. Urine analyses were performed by immunological screening (EMIT); hair analysis and confirmation tests in urine were performed by gas chromatography-mass spectrometry (GC-MS). Employees tested positive in urine for drugs of abuse numbered 2.8% in 2008, 2.03% in 2009, 1.62% in 2010, and 1.43% in 2011. As regards the second level of analysis, we observed that only one-third of the workers who had been tested positive for drugs of abuse were referred to an Addiction Treatment Unit in order to verify drug addiction. Our experience shows that, four years after approval of the law on WDT, the percentage of workers positive for drugs of abuse in urine has reduced in comparison to the first year. Moreover, our data show that most of the times employees who tested positive are tardily referred or not referred at all to a Public Addiction Treatment Unit to verify drug addiction. This makes us believe that the legal provisions are widely disregarded not paying the right tribute to the fact that Italy is one of few European countries with legislation on WDT.

    The aim of our study was to describe the distribution of Visceral Leishmaniasis (VL) in Italy, focusing on HIV-infected patients, to estimate the burden of the disease and the public health actions that should be undertaken. A review of official notifications and hospitalization data has been performed. From 2006 to 2008, a total of 289 cases of VL were notified; the overall notification rate was 1.63/1,000,000 (95% CI 1.45-1.83). In total, 1192 VL-associated hospitalizations were detected, with a hospitalization rate of 6.71/1,000,000 (95% CI 6.34-7.10). For the age group "≤ 24 years", a statistically significant increase was detected (p<0.05). A total of 68.9% (n = 821) of hospitalizations were detected in HIV-positive patients. The geographic distribution of rates revealed a significant increase in the north-eastern area of the country. Our study confirms that the epidemiological pattern of VL is changing and that, in Italy, control measures and preventive strategies should be based on not only the official notification system but also hospital data. This would lead to the identification of areas of parasite spread and to the creation of awareness campaigns geared toward general practitioners in the affected areas. Easy case detection would allow for timely public health actions and strategies for the implementation of more effective interventions for reservoir control.

    Full Text Available Italy is a point of reference for the conservation community worldwide, but it has yet to make a definitive leap towards preventive conservation. This paper examines some of the reasons to explain this, in the hope that this may be useful for other countries.

    Traina, Francesco

    2009-02-01

    At the present time, legal actions against physicians in Italy number about 15,000 per year, and hospitals spend over 10 billion euros (approximately US$15.5 billion) to compensate patients injured from therapeutic and diagnostic errors. In a survey summary issued by the Italian Court for the Rights of the Patient, between 1996 and 2000 orthopaedic surgery was the highest-ranked specialty for the number of complaints alleging medical malpractice. Today among European countries, Italy has the highest number of physicians subject to criminal proceedings related to medical malpractice, a fact that is profoundly changing physicians' approach to medical practice. The national health system has paid increasingly higher insurance premiums and is having difficulty finding insurance companies willing to bear the risk of monetary claims alleging medical malpractice. Healthcare costs will likely worsen as Italian physicians increasingly practice defensive medicine, thereby overutilizing resources with the goal of documenting diligence, prudence, and skill as defenses against potential litigation, rather than aimed at any patient benefit. To reduce the practice of defensive medicine and healthcare costs, a possible solution could be the introduction of an extrajudicial litigation resolution, as in other civil law countries, and a reform of the Italian judicial system on matters of medical malpractice litigation.

    The aim of this study is to make a synthesis about the development of electric-powered vehicles, in particular in Italy. After a brief historical review of this type of propulsion system, a state-of-the-art review is made which allows to show up the different existing architectures and their characteristic specificities. This review allows to identify the key scientific and technical domains in the existing research programs in progress in order to make these 'alternative' transportation systems economically viable. The second part of the study explains the situation of Italy with respect to these propulsion systems. The political commitments are analyzed first and then some of the university and industry centers of competences for these key domains are presented. Finally, some trans-national collaborations in progress are shown. (J.S.)

The Bilateral Legislation – 3.4. A Possible Collaboration – 4. Conclusion.   Abstract: In Italy imams are more than 800 members. As imams, they are almost all self-taught people. As citizens, most of the times they have a precarious job. During the week, they normally take care of things other than religion. They perform religious functions in their spare time. Moreover, to see them working as imams, you have to go down in some underground parking or in apartments converted into mosques, where sometimes you see minaret and other Islamic symbols, but only in either the picture or in the paintings hanging on the wall. In the end of the day, we know little or almost nothing about imams. Besides, the Italian law normally do not recognise them as religious authorities. Nevertheless, as imams they play a very important role in local Muslim communities that, under the pressing process of immigration, hold nowadays more than two millions persons. The paper will analyse the status of Islamic imams in Italy, comparing them with the status of other religious authorities (priests, rabbis, pastors ecc.. In particular, this comparative perspective will be focused on both angles: on the one hand, the research will compare the role of imams with those of religious authorities within their respective community; on the other, we will compare imams with considered the different way through which Italian law treats both imams and other religious authority. This perspective will give us a possibility to underline how both the social context and the Italian legal framework (regulating the State

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

    Full Text Available This paper presents an empirical and theoretical analysis of the financialization of companies and the diffusion of shareholder value maximization in Italy. Unlike the anglo-saxon contexts, financial accumulation and short-termism in Italy are not a consequence of institutional investors’ activism: Italian capitalism is still a holigarchic family capitalism, and few blockholders are in control of Italian large firms. Financialization of companies and the orientation to maximize shareholder value in Italy are rather the outcome of isomorphic processes, supported by institutional and legal transformations occurred since 1980s: reforms of finance, company and labour law, the privatization of state firms, the diffusion of finance-oriented accounting rules. The statutory reforms enabled the dominant coalitions within Italian capitalism to operate in a regulatory framework harmonized with a transnational context, largely assimilated to Anglo-Saxon norms, promoting a finance-oriented conception of control and managerial practices.En este trabajo se presenta un análisis empírico y teórico de la financiarización de las empresas y la difusión de la maximización del valor para los accionistas en Italia. A diferencia de los contextos anglosajones, la acumulación financiera y el cortoplacismo en Italia no son una consecuencia del activismo de los inversores institucionales: el capitalismo italiano es todavía un capitalismo familiar holigarchic, y pocos son blockholders en el control de las grandes empresas italianas. La financiarización de las empresas y la orientación para maximizar el valor para los accionistas en Italia son más bien el resultado de los procesos isomórficos, con el apoyo de las transformaciones institucionales y legales ocurrieron desde 1980: las reformas de las finanzas, empresa y derecho laboral, la privatización de empresas estatales, la difusión de finanzas- normas de contabilidad orientados.

    On 26 February, two of CERN's Directors-General had a very official handshake. Luciano Maiani, CERN's current Director-General, and Carlo Rubbia, one of his predecessors and current "commissario straordinario" of ENEA (Ente per le Nuove tecnologie, l'Energia e l'Ambiante, Institute for new technologies, energy and the environment) signed a collaboration agreement between their two organisations. ENEA carries out applied research in various fields such as renewable energies, new materials and medical applications. The organisation, which employs 3400 people in 10 laboratories in Italy, has a clear interest, therefore, in the technologies developed at CERN, which, in turn, seeks to promote them. Their collaboration will shortly lead to common research projects. CERN now has two Italian partners : INFN, its historical partner for particle physics research and ENEA for technological applications.

    This paper, through illustrative cases of homicidal typologies, examines the generally accepted theories on the subject: 1) sociological ones by Lorenz to Sutherland and Cressey, by Berkowitz to Wolfgang and Ferracuti and others; 2) neurobiological ones, which include the involvement of the limbic, hippocampal and parietal lobes of the brain; 3) the psychological (psychodynamic) ones which are not disjoint from the types of individual criminal homicide and related aspects. In the discussion of the types of murders, family and extrafamilial murders are then taken into consideration, with the various meanings of revenge, challenge, other reasons linked to robbery, theft, settling scores leading to youth gangs and drive-by-shootings of marginalized adolescents, crimes related to drugs and to mental disorders. Infanticide and multiple murder, including mass murder and serial killer, conclude the work together with the statistics of murders and family murders in Italy compared to USA, specifically to the crime clock.

    Ground-penetrating radar has been increasingly played an important role over the last 15 years in Italy due to its high reliability in assisting the assessment of the built environment for civil engineering purposes, and in being used for geophysical investigations within many other fields of application. In line with this, original works involving fundamental aspects of this technique and implementing its use more practically in a number of interesting projects have been developed over years, both under a research and an enterprise point of view. This paper will endeavour to review the current status of ground-penetrating radar activities in Italy. Efforts have been devoted to single out the most interesting national research projects, both recent and ongoing, involving ground-penetrating radar in Italy, such as the ARCHEO project in the 90s, funded by the Italian Ministry for Universities, wherein a stepped frequency ultra-wide band radar suited for archaeological surveys was manufactured. In this framework, it is worth citing another important and more recent project, European Community funded, namely, ORFEUS, which started in the late 2006 with the overall aim of providing the capability to locate buried infrastructure accurately and reliably by means of a bore-head ground-penetrating radar for horizontal directional drilling. A review on the main use of this non-destructive technique in management activities of national resources and infrastructures has been also performed, ranging from the applications made by Anas S.p.A., i.e., the main management authority for the Italian road and motorway network, up to private enterprises specialized in both services providing and ground-penetrating radar manufacturing such as, to cite a few, Sineco S.p.A. and IDS Ingegneria dei Sistemi S.p.A., respectively. Current national guidelines, rules or protocols to be followed during radar surveys have been also reviewed. Unlike well-established international standards such as

    Italy is the first European and world's fifth largest producer of geothermal energy for power generation which actually accounts for less than 2% of the total electricity production of the country. In this paper after a brief introduction to the basic elements of high-enthalpy geothermal systems, we discuss the potentialities represented by the submarine volcanoes of the South Tyrrhenian Sea. In particular we focus on Marsili Seamount which, according to the literature data, can be considered as a possible first offshore geothermal field; then we give a summary of the related exploitation pilot project that may lead to the realization of a 200MWe prototype power plant. Finally we discuss some economic aspects and the development perspectives of the offshore geothermal resource taking into account the Italian energy framework and Europe 2020 renewable energy target.

    This project consists of four separate buildings; three terraces comprising 24 dwellings in all, and one four-storey housing block containing 16 flats. The principal objective was to build low-cost housing in which innovative passive solar components could be incorporated at costs acceptable for public housing schemes (maximum 10% of the overall cost). An 'open-loop passive system', developed in Italy about 20 years ago by Barra-Costantini, was chosen. Warm air produced in the solar air panel circulates freely in the storage ceiling, into the rooms and back to the bottom of the air panel by gravity. The system supplies 30% of the net space-heating load. (author)

  2. Tuscany (Italy) 1990 regional energy balance

    Energy Technology Data Exchange (ETDEWEB)

    Gazzarrini, M.; Santoprete, G. (Pisa Univ. (Italy). Dipt. di Economia Aziendale)

    This paper first discusses the overall problems involved in the preparation of functional and reliable regional energy balance sheets. It then presents and analyzes the 1990 energy balance sheet prepared for the Tuscany Region of Italy. The problems cited basically deal with the availability, compatibility and accuracy of regional energy data. Trends in Tuscany's energy consumption are compared with national figures in order to give some useful indications as to future energy strategies to be taken into consideration by the regional administration. In fact, this Region reflects the main national energy policy weakness - over-dependency on foreign supplied petroleum. It is thus recommended that locally available geothermal energy sources be further developed.

    The aim of this study was to explore the extent and the specific features of drop-out for patients having a first contact with an university psychiatric outpatient clinic in Italy over the course of 1 year and to determine which variables were associated with early termination of treatment. Of the 158 patients selected for this study, there was an overall 3-month drop-out rate following the first visit of 63%. Of the 59 patients who had returned once after the initial contact, 28 interrupted subsequently the treatment, although the therapist's plan included further visits. The overall drop-out rate at 3 months was thus 82%. The only 2 variables associated with drop-out rates were the patients' perception of the severity of their disorder and the psychiatric history: continuing patients were more frequently in agreement with the clinician's judgment as compared with those who dropped out and were more likely to have already been in psychiatric treatment.

    Full Text Available The present study aimed at identifying the procedures for current methods of religious slaughter. It consisted of spot visits in abattoirs carried out from October 2008 to March 2009 in Italy. The species covered were cattle, sheep and poultry. During this period, five abattoirs in three different Italian regions were assessed. All the animals were slaughtered without stunning. A reliable protocol was developed to record each animal during slaughter, to get 329 minutes and 28 seconds of video. 313 animals were observed by video image analysis for both halal slaughter and shechita. Observed parameters are discussed in the light of animal welfare. Remarks on restraining methods as well as post-cut clinical indicators of consciousness are considered.

    Full Text Available Coenagrion ornatum (Sélys, 1850 is a damselfly ranging from northwestern Europe to southwestern Asia. It is highly local, and northwestern populations are experiencing a steep decline. In Europe, Coenagrion ornatum is a species of conservation interest and is listed as Near Threatened due to habitat loss; it is nearly extinct in Italy. We report the finding of 4 male C. ornatum on 3 June 2005 in Apulia, southeastern Italy. This is the only recent record for Italy, and highlights the need for further research on this species in the country.

    "Bangladeshis are one of a wide variety of recently established immigrant groups in Italy, analysed here as an example of the interaction of geopolitics, employment and survival strategies, and the micropolitics of the community's organization in Italy. The geopolitics involves events in Bangladesh (change of government), Italy (the Martelli Law and other legislation), Europe (EU and other European policies, and the opening of eastern Europe as a routeway) and the Gulf. The micropolitics concerns mechanisms of immigration, migration sponsorship, connections to Italian political groups and clientelistic relationships within the community. Micropolitics also governs to a large extent the types of mostly informal work done by Bangladeshis in Rome."

    New 40Ar/ 39Ar and 14C ages have been found for the Albano multiple maar pyroclastic units and underlying paleosols to document the most recent explosive activity in the Colli Albani Volcanic District (CAVD) near Rome, Italy, consisting of seven eruptions (Albano 1 = oldest). Both dating methodologies have been applied on several proximal units and on four mid-distal fall/surge deposits, the latter correlated, according to two current different views, to either the Albano or the Campi di Annibale hydromagmatic center. The 40Ar/ 39Ar ages on leucite phenocrysts from the mid-distal units yielded ages of ca. 72 ka, 73 ka, 41 ka and 36 ka BP, which are indistinguishable from the previously determined 40Ar/ 39Ar ages of the proximal Albano units 1, 2, 5 and 7, thus confirming their stratigraphic correspondence. Twenty-one 14C ages of the paleosols beneath Albano units 3, 5, 6 and 7 were found for samples collected from 13 proximal and distal sections, some of which were the same sections sampled for 40Ar/ 39Ar measurements. The 14C ages were found to be stratigraphically inconsistent and highly scattered, and were systematically younger than the 40Ar/ 39Ar ages, ranging from 35 ka to 3 ka. Considering the significant consistence of the 40Ar/ 39Ar chronological framework, we interpret the scattered and contradictory 14C ages to be the result of a variable contamination of the paleosols by younger organic carbon deriving from the superficial soil horizons. These results suggest that multiple isotopic systems anchored to a robust stratigraphic framework may need to be employed to determine accurately the geochronology of the CAVD as well as other volcanic districts.

  11. Energy Policies of IEA Countries: Italy [Italian Version, Executive Summary

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2010-07-01

    This review analyses the energy challenges facing Italy and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Italy towards a more sustainable energy future. The Italian government has made substantial progress in a number of sectors since the last IEA in-depth energy policy review in 2003. The success of the green certificate and white certificate schemes and continued reform of the electricity and natural gas supply markets are just a few examples and build on the recommendations contained in the previous review. Nonetheless, many challenges remain. Italy recognises the need to diversify its energy supply portfolio to reduce its heavy dependence on fossil fuels and electricity imports, and to decrease its growing greenhouse gas emissions. In 2008, the government announced its intention to recommence the countrys nuclear power program and start building a new nuclear power plant by 2013. To do so, Italy must first develop an efficient process for identifying critical energy infrastructure, including nuclear power, and subjecting it to an effective, streamlined siting and permitting process. Italy will face another major challenge in complying with Europe’s new climate and energy package, particularly in relation to renewable energy and emissions targets. Italy must step up efforts to comply with its new responsibilities, specifically by developing and putting in place a comprehensive climate change strategy for the years until 2020. In mid-2009, the legislature enacted a comprehensive new law that will facilitate the emergence of a robust long-term energy policy. The government must respond to this opportunity and elaborate, with industry, a comprehensive long-term strategy for the development of the energy sector. This review analyses the energy challenges facing Italy and provides sectoral critiques and recommendations for further policy improvements. It is intended to help guide Italy towards a more

    Some 21 years after its people voted in a referendum to end nuclear energy production, Italy looks set to return to the power of the atom. The newly installed right-wing government of Silvio Berlusconi has vowed to start building a new set of nuclear reactors within five years as part of a plan to reduce Italy's enormous energy costs. Experts, however, believe that this timescale is unrealistic.

  17. Estimated prevalence of multiple sclerosis in Italy in 2015.

    2017-03-01

    Italy is a high risk area for multiple sclerosis (MS) as confirmed by the numerous prevalence and incidence studies conducted in several regions/districts of the country. Nevertheless, there are no recent published epidemiological data, nor studies about the total prevalence of MS in Italy. Our aim was to update as of 2015 the prevalence rates of MS in different geographical areas using already published epidemiological studies, and to estimate the overall prevalence of the disease in Italy. We made a search in MEDLINE database of all published studies on epidemiology of MS in Italy. Then, we applied, to the already published prevalence data, the last published incidence and mortality rates to recalculate, as of 2015, the prevalence of MS. So, we calculated the mean prevalence rate from our extrapolations, and we applied it to the population in 2015 to estimate the number of MS patients in Italy. Our prevalence extrapolations ranged from 122 to 232 cases/100,000 in the mainland and Sicily, with an average of 176/100,000, and from 280 to 317 cases/100,000 in Sardinia with an average of 299/100,000. Applying these media to the Italian population in 2015, we obtained an estimate of more than 109,000 MS patients in Italy. Our estimates were higher than the latest published rates but consistent with the annual increase of prevalence due to incidence that exceeds mortality, with the increase of survival and, maybe, with the probable increase of incidence.

    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. Italian hallmarks in the management of allergic diseases in childhood are a quite alive and spread interest in

    Full Text Available Abstract Background The present paper is a brief survey on the ethnobotanical works published by the Authors since 1981, concerning the research carried out in some southern and central Italian regions. Before Roman domination these territories were first inhabited by local people, while the southern areas were colonized by the Greeks. These different cultural contributions left certain traces, both in the toponyms and in the vernacular names of the plants and, more generally, in the culture as a whole. Methods Field data were collected through open interviews, mainly of farmers, shepherds and elderly people, born or living in these areas for a long time. Voucher specimens of collected plants are preserved in the respective herbaria of the Authors and in the herbarium of "Roma Tre" University. Important contributions have been made by several students native to the areas under consideration. A comparative analysis with local specific ethnobotanical literature was carried out. Results The paper reports several examples concerning human and veterinary popular medicine and in addition some anti-parasitic, nutraceutic, dye and miscellaneous uses are also described. Moreover vernacular names and toponyms are cited. Eight regions of central and southern Italy (particularly Latium, Abruzzo, Marche and Basilicata were investigated and the data obtained are presented in 32 papers. Most of the species of ethnobotanical interest have been listed in Latium (368 species, Marche (274 and Abruzzo (203. The paper also highlights particularly interesting aspects or uses not previously described in the specific ethnobotanical literature. Conclusion Phyto-therapy in central and southern Italy is nowadays practised by a few elderly people who resort to medicinal plants only for mild complaints (on the contrary food uses are still commonly practised. Nowadays therapeutic uses, unlike in the past, are less closely or not at all linked to ritual aspects. Several

    Landslides are one of the major natural threats to human lives, settlements and infrastructure. Permanent geoelectrical monitoring using the GEOMON4D instrumentation in combination with high resolution displacement monitoring by means of the DMS system was performed at an active landslide area in Italy (Bagnaschino). These sites are part of a geoelectrical monitoring network of the Geological Survey of Austria, which currently comprises six permanently monitored landslides in Europe. The Bagnaschino site represents a landslide/earthflow reactivated within an old landslide mass. The old landslide is situated on the slopes of the Val Casotto about 4 km SE of Torre Mondovì (NW Italy). Evident indications of deep-seated gravitational deformation suggest that the current slopes are in a condition of limit-equilibrium and are predisposed to slow instability, triggered most probably by rain and/or snow melting and river erosion at the foot. The recent landslide was activated during 1994 rainfall event. It covers an estimated area of 150,000 m² and comprises a displaced material of 1.2 million m³. It endangers a regional road and potential formation of a dam. For the purpose of early warning a DMS monitoring column with 60 m length was installed in October 2008. Total displacement recorded by DMS during the events between 2008 and 2010 was 600 mm. Subsequently, the GEOMON4D geoelectric monitoring system was installed there in 2010. Resistivity measurements are performed along a 224 m long profile, which is oriented parallel to the main movement direction. Its midpoint is next to the DMS station. One set of data comprising around 4000 gradient-type measurements is taken every 4 hours. For power supply a combination of a fuel cell and a solar panel is used. Within the observation interval one distinct displacement event was monitored. This event was accompanied by a decrease of electric resistivity. In addition to our standard analysis of resistivity data (e.g. time

  1. Rainfall thresholds for the possible occurrence of landslides in Italy

    2010-03-01

    Full Text Available In Italy, rainfall is the primary trigger of landslides that frequently cause fatalities and large economic damage. Using a variety of information sources, we have compiled a catalogue listing 753 rainfall events that have resulted in landslides in Italy. For each event in the catalogue, the exact or approximate location of the landslide and the time or period of initiation of the slope failure is known, together with information on the rainfall duration D, and the rainfall mean intensity I, that have resulted in the slope failure. The catalogue represents the single largest collection of information on rainfall-induced landslides in Italy, and was exploited to determine the minimum rainfall conditions necessary for landslide occurrence in Italy, and in the Abruzzo Region, central Italy. For the purpose, new national rainfall thresholds for Italy and new regional rainfall thresholds for the Abruzzo Region were established, using two independent statistical methods, including a Bayesian inference method and a new Frequentist approach. The two methods proved complementary, with the Bayesian method more suited to analyze small data sets, and the Frequentist method performing better when applied to large data sets. The new regional thresholds for the Abruzzo Region are lower than the new national thresholds for Italy, and lower than the regional thresholds proposed in the literature for the Piedmont and Lombardy Regions in northern Italy, and for the Campania Region in southern Italy. This is important, because it shows that landslides in Italy can be triggered by less severe rainfall conditions than previously recognized. The Frequentist method experimented in this work allows for the definition of multiple minimum rainfall thresholds, each based on a different exceedance probability level. This makes the thresholds suited for the design of probabilistic schemes for the prediction of rainfall-induced landslides. A scheme based on four

    Technological progresses and the changed way to collect, access and use data are at the bottom of the European Commission proposal for a "General Data Protection Regulation" (25 January 2012). Implications of safeguarding privacy and harmonization of existing rules are extremely important also for national Health Systems. Mobility of patients and health professionals as well as cross-border healthcare connected with the increasing use of Information and Communication Technologies in Healthcare Services are modifying traditional medical approaches and applications. New tools, as Electronic Health Records, provide significant benefits as empowering health consumers and minimizing health costs. Anyway, EHRs have limits: for example, they should cause risks for individuals, professionals and institutions in terms of personal injuries and liabilities. In this scenario, it's evident that technical aspects (as health standards and interoperability) are as important as legal and regulatory privacy issues. Presently, mandatory acts on the protection of individuals with regard to the processing of health e-Data still missing at all levels. Italy is adopting binding and non-binding legal documents to tackle the problem. Are they enough?

  3. The first book museums in Italy

    Full Text Available Just before the advent of Fascism, in Turin, in the nearby town of Carmagnola and in Florence were born the first Italian examples of book museums. It was early and exceptional experiments of valorizing of book history and of the ancient techniques of manufacturing manuals in a time of great innovation. The first, called the National Museum of the book, was opened in 1913 as a result of the exhibition of the history of printing held during the Universal Exhibition of 1911; the second, created in 1921, was the result of collecting a notable family that took up the typographic tradition of Carmagnola old more than 4 centuries; the third, said Museum of books and illumination, was the result of the exploitation of the extraordinary collections of the Medici library and of the policy pursued by the Director Guido Biagi. Of such museums, outlining the events that led to their creation, only the museum in Carmagnola has come to this day, while the others for various reasons, were closed and never reconstituted. The contribution also provides an opportunity to reflect on the creation of a new museum of the book in Italy at a time when libraries lack visibility into the organization of the Ministry of cultural heritage, which could be distributed and polycentric in the offices of the State libraries in Rome, with its hub at the National Central Library.

    Full Text Available Introductions of non-indigenous crayfish have received great attention from biologists and policy makers during the last decade. Purposes of this study are to update the knowledge about the crayfish distribution in Latium (central Italy, and to show how interactions between indigenous and non-indigenous species can affect their distribution. The main findings of this study were (1 the great decrease of the Austropotamobius pallipes populations and (2 the alarming spread of the four non-indigenous species red swamp crayfish Procambarus clarkii (the main widespread crayfish, spiny-cheek crayfish Orconectes limosus, narrow-clawed crayfish Astacus leptodactylus, and yabby Cherax destructor. We never observed indigenous and non-indigenous crayfish living in syntopy, although we noted that white-clawed crayfish had become extinct at sites where non-indigenous crayfish species exist now. Other type of problems (i.e. illegal harvesting and over-abstraction of water for human use can also reduce the distribution and abundance of the indigenous crayfish stocks. The distribution of Italian crayfish populations has not been studied sufficiently and more studies are required nationwide to assess the conservation status of A. pallipes and the occurrence of non-indigenous species. A national database of crayfish records ought to be constructed and regularly updated.

    Full Text Available Four Pleistocene bathyal molluscan assemblages from southern Italy (Calabria and Messina area were studied. One hundred and thirty-six species were recorded. Twenty-four were classified and described in detail and thirty-five were illustrated. The following new combinations are pro posed: Solariella marginulata (Philippi, 1844, Iphitus tenuisculptus (Seguenza, 1876, Benthomangelia tenuicostata (Seguenza, 1879, Chrysallida microscalaria (Seguenza, 1876, Ennucula corbuloides (Seguenza, 1877, Ennucula rotundata (Seguenza, 1877, Thestyleda cuspidata (Philippi, 1844, Katadesmia confusa (Seguenza, 1877, Austrotindaria pusio (Philippi, 1844, Austrotindaria salicensis (Seguenza, 1877.

The assemblages are dominated by nuculoids and fit the general compositional pattern of the deep-sea molluscan communities. A paleodepth of 500-600 m is inferred for two assemblages, whereas a greater depth, pro bably not exceeding 1,000 m, is suggested for the other two. Taxonomic affinities with northeast Atlantic and more generally with World Ocean deep-sea molluscan faunas are remarkable. The Plio-Quaternary evolution of the deep Mediterranean benthos is discussed.    

  7. Native and alien squirrels in Italy

    Sandro Bertolino

    2000-09-01

    Full Text Available Abstract In Italy there are four species of squirrels: the native red squirrel and other three species recently introduced. The red squirrel is present in the Italian peninsula with three subspecies, and is missing only in Salento, and Italian islands. This species is common on Alps and Apennines, while in the plains it is declining because of the habitat loss. Competition with the grey squirrel and habitat fragmentation are considered the major threats to the survival of the red squirrel. The grey squirrel is present in Piedmont and Liguria. A study on the Piedmontese colony showed that the red squirrel is disappearing from the area colonised by the grey squirrel and the damage due to bark-stripping and feeding is considerable. Free-ranging populations of the Siberian chipmunk live in Belluno, Verona, and Rome, but records of single animals were reported for other areas. The Finlayson's squirrel is present with a small nucleus in an urban area of Piedmont. Here, the impact of this species on the vegetation appears dramatic. The eradication of the grey squirrel is a priority for the conservation of the red squirrel, but control plans for the other introduced species are also needed.

The recent category of advanced therapy medicinal products has been created to comprise cellular, gene therapy, and tissue engineered products, as a new class of drugs. Their manufacture requires the same pharmaceutical framework as for conventional drugs and this means that industrial, large-scale manufacturing process has to be adapted to the peculiar characteristics of cell-containing products. Our hospital took up the challenge of this new path in the early 2000s; and herein we describe the approach we followed to set up a pharmaceutical-grade facility in a public hospital context, with the aim to share the solutions we found to make cell therapy compliant with the requirements for the production and the quality control of a high-standard medicinal product.Keywords: advanced therapy medicinal product, good manufacturing practices, stem cells

    Full Text Available Background. The objectives of the study were to document knowledge, attitudes, and behaviors of women regarding cardiovascular diseases (CVDs and the determinants associated. Materials and Methods. The cross-sectional survey was conducted among a random sample of 830 women older than 18 years from the general population in Italy. Results. Almost all participants reported having heard about CVDs, and among them 89.4% and 74.7% identified smoking and high cholesterol level as risk factors. Only 26.5% identified the main CVDs risk factors. Women more knowledgeable were married and better educated and self-perceived a worse health status. Only 23% knew the main CVDs preventive measures and this knowledge was significantly higher in women who are unemployed, who are more educated, who have received information about CVDs from physicians, and who know the main risk factors. Respondents with lower education, those with at least three children, those who self-perceived a worse health status, and those who need information were most likely to have a positive attitude toward the perceived risk of developing CVDs. Women with two or three children or more were at high risk profiles 49% and 56% lower than women with one child. Conclusions. Educational programs are needed among women as support to improve knowledge and appropriate behavior about CVDs.

  11. Ionospheric precursors for crustal earthquakes in Italy

    2010-04-01

    Full Text Available Crustal earthquakes with magnitude 6.0>M≥5.5 observed in Italy for the period 1979–2009 including the last one at L'Aquila on 6 April 2009 were considered to check if the earlier obtained relationships for ionospheric precursors for strong Japanese earthquakes are valid for the Italian moderate earthquakes. The ionospheric precursors are based on the observed variations of the sporadic E-layer parameters (h'Es, fbEs and foF2 at the ionospheric station Rome. Empirical dependencies for the seismo-ionospheric disturbances relating the earthquake magnitude and the epicenter distance are obtained and they have been shown to be similar to those obtained earlier for Japanese earthquakes. The dependences indicate the process of spreading the disturbance from the epicenter towards periphery during the earthquake preparation process. Large lead times for the precursor occurrence (up to 34 days for M=5.8–5.9 tells about a prolong preparation period. A possibility of using the obtained relationships for the earthquakes prediction is discussed.

    Full Text Available The aim of this research was to survey current mechanization level of coppice harvesting in Southern Italy. The cooperation of the General Direction of the National Forest Service (NFS has been a basic tool of survey. A questionnaire compiled on purpose was sent to each Forest Station (hereinafter referred to as CS in the following regions: Basilicata, Campania and Calabria. A high percentage (80% of the CSs did fulfill the questionnaire. The answers highlight that: i the main assortment currently produced is firewood; ii the level of harvesting mechanization is rather low, equipment being quite obsolete: indeed, the most widely used machineries are farm tractors partly adapted to forest harvesting and equipped with cages or back winch; iii the use of animals for hauling (mules and oxen, the latter in Calabria is still quite frequent, while forest tractors, polyethylene chutes and cable cranes are almost absent; iv the use of individual protection (DPI and machinery protection devices (DPM is on average quite low.

In particular the author pays the attention to polemics devoted to the information freedom protection. The existence of media empires in modern mass media hinders one of the main functions of the press, namely the spreading of objective and full information on all sides of the society life directed by plurality in informational and analytical material. At the same moment in time the mass media influence on the fates of the leading political figures, Silvio Berlusconi in particular. A topical problem of complex relations of modern press and different political, social and power structures is analyzed on the Italian example.

  14. The Ignimbrite Campana Magma Chamber: Pre-eruptive P-t-x Conditions From Melt Inclusion Data

    Science.gov (United States)

    Marianelli, P.; Proto, M.; Sbrana, A.

    The Ignimbrite Campana (36 ka) represents the most powerful eruption characterizing the volcanic history of the Campi Flegrei caldera. The eruption was fed by a stratified magma chamber (Civetta et al., 1997). This study, based on melt inclusion investigations in phenocrysts of pumice, is aimed to better constrain depth, thermal conditions and composition of magmas hosted in the magma chamber. Samples from the Breccia Museo products (proximal deposits of the Ignimbrite Campana) were selected, due to their sin-eruptive and sin-depositional quenching. On the basis of melt inclusions investigations important informations about crystallization conditions (P, T, X) and volatile contents have been obtained. Glass compositions fall in the trachyte field close to the trachyte-phonolite boundary, similarly to the others Ignimbrite Campana products. The temperature of homogenization ranges between 850 and 1135°C. These values of temperature, that can be assumed as crystallization temperatures, correlate to the host crystal compositions with the highest one corresponding to melt inclusions trapped in less Fe-rich pyroxene. FTIR analyses on double -polished melt inclusions were carried out in order to investigate H2O and CO2 contents. Preliminary results indicate values of H2O that range from about 2 up to 8.0wt%, whereas CO2 was not detected. Lowest values of H2O (modal value = 2- 3wt%) correspond to the melt inclusions from layers at the top of the Breccia Museo (pumice flow deposits). Minimum pressures of crystallization are estimated in the range 100-200 MPa, assuming saturation conditions for the trapped melts and calculating the solubility of H2O in trachytic magmas according to the model of Moore et al. (1998). References Civetta L., Orsi G., Pappalardo L., Fisher R.V., Heiken G., Ort M.

    2014-05-01

    The high topographic and vegetation heterogeneity makes Italy vulnerable to forest fires both in the summer and in winter. In particular, northern regions are predominantly characterized by a winter fire regime, mainly due to frequent extremely dry winds from the north, while southern and central regions and the large islands are characterized by a severe summer fire regime, because of the higher temperatures and prolonged lack of precipitation. The threat of wildfires in Italy is not confined to wooded areas as they extend to agricultural areas and urban-forest interface areas. The agricultural and rural areas, in the last century, have been gradually abandoned, especially in areas with complex topography. Many of these areas were subject to reforestation, leading to the spread of pioneer species mainly represented by Mediterranean conifer, which are highly vulnerable to fire. Because of the frequent spread of fire, these areas are limited to the early successional stages, consisting mainly of shrub vegetation; its survival in the competition with the climax species being ensured by the spread of fire itself. Due to the frequency of fire ignition — almost entirely man caused — the time between fires on the same area is at least an order of magnitude less than the time that would allow the establishment of forest climax species far less vulnerable to fire. In view of the limited availability of fire risk management resources, most of which are used in the management of national and regional air services, it is necessary to precisely identify the areas most vulnerable to fire risk. The few resources available can thus be used on a yearly basis to mitigate problems in the areas at highest risk by defining a program of forest management interventions, which is expected to make a significant contribution to the problem in a few years' time. The goal of such detailed planning is to dramatically reduce the costs associated with water bombers fleet management and fire

  16. The Strategic Plan for Tourism Development in Italy

    2013-06-01

    Full Text Available Conceptual works on tourism destination competitiveness affirm the central importance of planning the process of value creation within destination. Italy is an emblematic case of why and how a leading tourism destination may lose competitiveness along the years. Up to the 1980s Italy was in fact the top international tourism destination, but then such ranking gradually decreased, because of more complexity of sector and, over all, because of marginality of tourism in the government agenda and more in general of the country. After years of strategic myopia, Italy finally has a tool that formalizes its vision and indicates the key factors that can be leveraged in order to regain ground. In 2013, Italy adopted a National Strategic Plan. Therefore, this paper aims to describe an important turning point in tourism policies for the economic and cultural development of Italy. The research highlights the problematic areas of Italy’s tourism industry and explains how a new approach should make the Italian destination able to successfully compete on the international tourism market.

  17. Update on the epidemiology of tuberculosis in Italy.

    2014-05-01

    As in many countries in Western Europe, in Italy tuberculosis (TB) is a relatively rare disease. In the last decade its incidence has remained constant at under 10 cases/100,000 inhabitants, the threshold considered to define a country as low prevalence. The epidemiological picture, however, is very different in the countries of Eastern Europe and in Africa, Asia, and Latin America, where the incidence of TB continues to increase and in some cases is accompanied by the emergence and spread of multidrug-resistant TB. The present review describes the epidemiology of TB in Italy. In 2008, the incidence rate was 3.8 cases per 100,000 for people born in Italy, and 50-60 cases per 100,000 for those born abroad. There was an increase in cases from Eastern Europe. The crude mortality rate for TB in 2006 was 0.7 deaths per 100,000 residents. Although TB is a low-prevalence disease in Italy, its epidemiology is changing. Since 1955, more than 160,000 people in Italy have died from this potentially preventable and curable disease.

    Full Text Available Giorgio Tamaro, Sergio ParcoDepartment of Laboratory Medicine, Children's Hospital, Burlo Garofolo, Trieste, ItalyAbstract: This study assesses the impact of immigration in Friuli Venezia Giulia, a region of northeastern Italy, on the epidemiological features of hemoglobin patterns and on prothrombotic and trisomy risk in pregnancy for patients of non-Italian origin. This study follows a series of studies on the incidence of thalassemia and other hemoglobinopathies with reduced globin chain synthesis, that were performed during the postwar (1939–45 period in Friuli Venezia Giulia following immigration into the region from Istria and Sardinia (regions of northern and central Italy. Current data show that today’s constantly growing immigration into the region differs from previous decades, in terms of origin and quantity of migrants, who mainly come from third world countries. This has a significant impact on health care issues, and more specifically on prospective health screening for foreigners. The authors conclude that scholastic education and hospital services, either public or private, and voluntary associations, may contribute to solving the problem, but only in terms of training and organization, for non-European Union citizens arriving in northern Italy and neighboring areas, especially those from Africa, Asia, Latin America, and eastern Europe.Keywords: immigration, hemoglobinopathy, pregnancy, trisomy, thalassemia trait, Italy

  19. Adaptively smoothed seismicity earthquake forecasts for Italy

    Yan Y. Kagan

    2010-11-01

    Full Text Available We present a model for estimation of the probabilities of future earthquakes of magnitudes m ≥ 4.95 in Italy. This model is a modified version of that proposed for California, USA, by Helmstetter et al. [2007] and Werner et al. [2010a], and it approximates seismicity using a spatially heterogeneous, temporally homogeneous Poisson point process. The temporal, spatial and magnitude dimensions are entirely decoupled. Magnitudes are independently and identically distributed according to a tapered Gutenberg-Richter magnitude distribution. We have estimated the spatial distribution of future seismicity by smoothing the locations of past earthquakes listed in two Italian catalogs: a short instrumental catalog, and a longer instrumental and historic catalog. The bandwidth of the adaptive spatial kernel is estimated by optimizing the predictive power of the kernel estimate of the spatial earthquake density in retrospective forecasts. When available and reliable, we used small earthquakes of m ≥ 2.95 to reveal active fault structures and 29 probable future epicenters. By calibrating the model with these two catalogs of different durations to create two forecasts, we intend to quantify the loss (or gain of predictability incurred when only a short, but recent, data record is available. Both forecasts were scaled to five and ten years, and have been submitted to the Italian prospective forecasting experiment of the global Collaboratory for the Study of Earthquake Predictability (CSEP. An earlier forecast from the model was submitted by Helmstetter et al. [2007] to the Regional Earthquake Likelihood Model (RELM experiment in California, and with more than half of the five-year experimental period over, the forecast has performed better than the others.

  20. The revised aeromagnetic anomaly map of Italy

    2004-06-01

    Full Text Available This paper presents the revised aeromagnetic anomaly map of Italy and its surrounding seas, projected at reference altitude of 2500 m and geomagnetic epoch 1979.0. The magnetic data set used for the map compilation is composed of the total intensity field data acquired partly during the aeromagnetic surveys performed by the Italian National Oil Company (Agip - Direzione Esplorazione Idrocarburi between 1971 and 1980, and during the new surveys committed by the Geophysical Corporate Services of Eni Spa - Exploration & Production Division in the years 2001-2002. In both campaigns the recorded data were very dense and uniformly distributed over the examined area. A detailed re-processing of this data set and a re-organization into a new digital database were carried out. The re-processing was done using modern adequate techniques, obtaining a remarkable exploitation of the data information content. The result is a colour shaded relief map that shows on a large scale many of the structural lineaments of the Italian area. The inclusion of a larger number of data and the subtraction of an appropriate magnetic reference field are the main reasons of an enhancement in the anomaly definition. This new map replaces the previous Agip version, and aims to become the reference aeromagnetic cartography of the Italian area. We think this work will be useful both for researchers interested in large scale tectonic studies, and for anyone interested in the investigation of smaller scale structures, such as volcanic complexes or infra-sedimentary magnetic bodies, as well as for mining research.

  1. The Ml Magnitude Scale In Italy

    Science.gov (United States)

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

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

    In plants and algae, sulfate assimilation and cysteine synthesis are regulated by sulfur (S) accessibility from the environment. This study reports the effects of S deprivation in autotrophic and heterotrophic cultures of Galdieria phlegrea (Cyanidiophyceae), a unicellular red alga isolated in the Solfatara crater located in Campi Flegrei (Naples, Italy), where H2S is the prevalent form of gaseous S in the fumarolic fluids and S is widespread in the soils near the fumaroles. This is the first report on the effects of S deprivation on a sulfurous microalga that is also able to grow heterotrophically in the dark. The removal of S from the culture medium of illuminated cells caused a decrease in the soluble protein content and a significant decrease in the intracellular levels of glutathione. Cells from heterotrophic cultures of G. phlegrea exhibited high levels of internal proteins and high glutathione content, which did not diminish during S starvation, but rather glutathione significantly increased. The activity of O-acetylserine(thiol)lyase (OASTL), the enzyme synthesizing cysteine, was enhanced under S deprivation in a time-dependent manner in autotrophic but not in heterotrophic cells. Analysis of the transcript abundance of the OASTL gene supports the OASTL activity increase in autotrophic cultures under S deprivation.

    Fluid withdrawal and injection into the crust produces changes in the local stress field and pore pressure, involving different rock volumes depending on the injection flow rate and duration as well as on the medium permeability. This process is in different cases correlated to induced seismicity. In the case of geothermal power plants (e.g. fluids withdrawal and in several case withdrawal/reinjection) this correlation is vague and sometimes not well constrained by experimental data. We report here a set of simulations of withdrawal, injection and withdrawal-reinjection-cycles from/in the same geothermal reservoirs, by using the numerical code TOUGH2®. The simulations are applied to conceptual models of different geothermal reservoirs already published in previous works, whose main difference is in the permeability features and the depth of wells (Soultz, France; Campi Flegrei caldera and Ischia island, Italy). The numerical simulations are aimed to compare the time growth of perturbed volumes obtained with withdrawal reinjection cycle to those obtained during simple withdrawal or injection, using the same flow rates. Our results clearly point out that reinjection is much less critical than simple injection or withdrawal, because the perturbed volumes are remarkably small and, moreover, remain constant over the simulated time, of whatever duration. This fact reduces significantly the potential of the seismicity induced by pressure variation into the reservoirs.

    2014-03-01

    Full Text Available The aim of study is to analyze the existing railway infrastructure and to develop the trains scheduling in the north-west of Italy for an efficient and sustainable urban development. The Genoa rail corridor, in north-west of Italy, has a very complex track configuration and complex junction intersections, with a constrained capacity network shared by a large number passenger and freight trains. In the present study a new methodology to create a modular, periodical and symmetrical train scheduling for Genoa, Italy rail corridor is proposed. The objective is to answer the necessities for a modern and irregular mobility, typical for large metropolitan areas. The understanding of preferred methods of transportation, amounts of commodities shipped and types of commodities shipped can provide vision into the resiliency of the transportation system and project future sustainable infrastructure improvements necessary to create more reliable and efficient methods of transportation.

    The purpose of this mini-review is to present the National Health System and services available for adolescents in Italy, and to review the most relevant data on morbidity and mortality in Italian teens. Adolescent medicine in Italy is not a separate speciality, but there are some distinct services for adolescents in paediatric departments or gynaecologic wards, mostly in large cities where university hospitals or hospital of national relevance are located. Primary health care in Italy is provided mainly by general practitioners (GPs) and pediatricians, and on-call physicians (Guardia Medica) for after-hours medical care and services. The number of centres providing care for adolescents in Italy is 4097 (50% of these are in the North of Italy, 20% in the Central regions and 20% in the South and Islands). The population of Italy on January 1st 2011 was approximately 60,477,881 and the number of adolescents, aged 10 to 19 years, was 6,214,000. The most frequent causes of death in adolescents are motor vehicle accidents - more than half of which are related to drug or alcohol use - followed by cancer and suicide. In primary care, adolescents present with a large number of issues, particularly upper respiratory infections, musculoskeletal problems, pain syndromes, obesity, eating disorders, dermatological issues, mood and somatoform disorders, school and mental health problems, and chronic fatigue, many of which require a coordinated, multidisciplinary management approach. The estimated population with a chronic illness is 8%. There are no specific protocols for the transition to adult medicine physicians for patients with chronic diseases or special health needs. In order to improve the quality and quantity of education in adolescent health for paediatricians and GPs, the Study Group of Emilia and Romagna Region for Adolescent Health Care (SGA-ER) is going to organize, beginning in 2012, a two year educational intervention course in adolescent health.

    Italy, after the vote of the referendum in 1987, stopped producing electricity from nuclear fuel for the energy demand. This paper analyses the current Italian energy outlook and clarifies how the choice to abandon the nuclear option damaged our economy. Nowadays, the possible reintroduction of civil nuclear option is hindered by groups claiming that nuclear energy is not convenient and is incredibly dangerous. In this paper it is clarified with international references how this is not correct and why Italy should start thinking seriously and without prejudices at future energy options.

    The author explores trends in migration from and within Italy and their impact on nationalism, politics, and social change. "In the last two centuries, Italy has witnessed significant population displacements. Firstly the seasonal emigration of the modern era: secondly, between 1880 and the immediate post-war (1950) [period], the European and transoceanic 'great emigration'. During the fifties and sixties, displacements took place within the peninsula from South to North. Finally, from the second half of the seventies, immigration from the...'Third world' began."

    We test the relationship between happiness and self-rated health in Italy. The analysis relies on a unique dataset collected through the administration of a questionnaire to a representative sample (n = 817) of the population of the Italian Province of Trento in March 2011. Based on probit regressions and instrumental variables estimates, we find that happiness is strongly correlated with perceived good health, after controlling for a number of relevant socio-economic phenomena. Health inequalities based on income, work status and education are relatively contained with respect to the rest of Italy. As expected, this scales down the role of social relationships.

    In Italy family is characterized by strong ties and is based on mutual aid of all its members. In the last 20 years, the structure of families has been significantly influenced by demographic, economic and professional changes, determining a transition from a patriarchal to a nuclear family model, with a higher number of single-parent families, single-person households, childless couples, same-sex couples. However, this transition has been slower than that occurring in other countries, probably as an ongoing impact of prevalent Catholic ideology. Major demographic changes in Italian families include, 1) a decrease in the number of marriages, delays in getting married and an high number of civil ceremonies, 2) a reduced birth rate; Italy is becoming one of the European countries with lowest growth rate, and with an increasing number of births out of wedlock, 3) an increased marital instability, with a constantly growing number of legal separations. Like many countries, relatives in Italy are highly involved in the care of patients with physical and mental disorders. There are a number of psychosocial interventions used in Italy including the 'Milan Systemic Approach' and family psycho-educational interventions. However, there are difficulties in implementing these interventions which are highlighted in this paper. We recommend research strategies to identify the best options to involve families in the care of mentally ill patients and to adequately support them.

    Systematic education based on internationally standardized programs is a well-established practice in Italy, especially in the emergency health care system. However, until recently, a specific program to treat burns was not available to guide emergency physicians, nurses, or volunteers acting as first responders. In 2010, two national faculty members, acting as ABA observers, and one Italian course coordinator, trained and certified in the United States, conducted a week-long training program which fully certified 10 Italian instructors. Authorized ABLS provider courses were conducted in Italy between 2010 and 2012, including one organized prior to the 20th annual meeting of the Italian Society of Burns (SIUst). In order to increase the effectiveness and diffusion of the course in Italy, changes were approved by the ABA to accommodate societal differences, including the translation of the manual into Italian. The ABA has also approved the creation and publication of a bilingual ABLS Italian website for the purpose of promoting the ABLS course in Italy. In response to high demand, a second ABLS Instructor course was organized in 2012 and has been attended by physicians and nurses from several Italian burn centers. In the following discourse the experiences of the first 15 Italian ABLS courses will be discussed.

    Full Text Available Klebsiella pneumoniae carbapenemase (KPC was detected in two isolates of carbapenem-resistant K. pneumoniae in an italian teaching hospital. This is the first report of a KPC-producing isolates in our country. The first strain was isolated from a urine sample collected from a indwelling urinary catheter in a ICU-patient with subdural haematoma, while the second was from the culture of the central venous catheter (CVC in a patient affected by Crohn’s disease admitted in gastroenterology ward. Both were resistant to all ß-lactams, susceptible to imipenem and meropenem and resistant to ertapenem.They were resistant to other classes of non-ß-lactams antibiotics such as quinolones, aminoglycosides (with the exception of amikacin, trimethoprim-sulfamethoxazole (TMP-SMX as well as to nitrofurantoin.The isolates were not associated with travel abroad.They were found to contain the plasmid encoded carbapenemase gene blaKPC and were also positive to the Hodge’s test.The detection of KPC-producing bacteria has important implications in infection control and public health. The K. pneumoniae carbapenemase (KPC belong to class A ß-lactamases of the functional group 2f. Reported for the first time in U.S. in 2001, these agents were subsequently identified in Europe. KPC strains are typically resistant to penicillins, extended-spectrum cephalosporin and aztreonam and present a peculiar behavior against carbapenems in that MIC is close to the susceptibility value or is borderline (except for ertapenem.This pattern is often associated with resistance to quinolones.The information is conveyed by the resistance plasmids, thus explaining their diffusion and implication in outbreaks of KPC. Despite this, to date there are few reports concerning the isolation of this phenotype in Italy.The purpose of this paper is to present two clinical cases related to the isolation of KPC in our hospital. The KPC-producing strains have been respectively isolated: the first

  13. Societal and individual landslide risk to the population of Italy

    2010-05-01

    Landslides cause damage to people every year in Italy. The number of fatalities (deaths and missing persons) and the number of casualties (deaths, missing persons, and injured people) are a direct, quantitative measure of the intensity of a disaster, and can be used to evaluate individual and societal risk quantitatively. Individual-risk criteria are expressed using mortality (or death) rates, which are given by the number of deaths per 100,000 people, in a given period. Societal-risk criteria are commonly established constructing frequency-consequences plots. In these plots, the number of losses (deaths, fatalities, or casualties) in each event is plotted versus the frequency of the event. Societal risk is then determined investigating the relationships linking the frequency of the events to their intensity, measured by the number of the losses. We have updated existing estimates of societal and individual landslide risk in Italy. For our assessment, we have used an improved version of the catalogue of historical landslide events that have resulted in loss of life, missing persons, injured people, and homelessness in Italy, from 1850 to 2008. This is the recent portion of a larger catalogue spanning the 1941-year period from 68 AD to 2008. This information was used to update the existing national estimates and to obtain first regional estimates of societal and individual landslide risk in Italy. To model the distribution of the frequency of landslide events with casualties in Italy, and in each of the 20 Regions in Italy, we adopted a Zipf distribution. We used the scaling exponent of the probability mass function (PMF) of the intensity of the events, which controls the proportion of small, medium and large events, to compare societal landslide risk levels in different geographical areas and for different periods. To consider the frequency of the events with casualties, we have scaled the PMF obtained for the individual Regions to the total number of events in

  15. Mother's educational level and single motherhood: Comparing Spain and Italy

    Directory of Open Access Journals (Sweden)

    Anna Garriga

    2015-12-01

    Full Text Available Background: During the second half of the 20th century there was a positive relationship between single parenthood and the mother's educational level in Spain and Italy. Objective: However, several important transformations contemplated by Goode (1993 and McLanahan (2004 suggest that this relationship may have been inverted in Spain but perhaps not in Italy. The purpose of our study is to test this hypothesis. Methods: We use EU_SILC data from waves 2005 and 2011 and logistic regressions. Results: We found the relationship between the mother's educational level and being a single mother is negative in Spain, while it is not significant in Italy. However, we found that for Italian mothers aged 40 and younger and mothers from northwest Italy, this relationship is also negative. By contrast, for older mothers and mothers from the islands or southern Italy, this association is positive. Meanwhile, for mothers from the central and northeast regions, the relationship between educational level and single motherhood is not significant. Conclusions: These results show how Spain and some parts of Italian society are moving towards family models similar to those in the Northern European countries. As Sara McLanahan (2004 noted for the United States, this social transformation in Southern Europe cannot be considered without recognizing the potential negative consequence for future generations. The single-mother households dealing with the economic crisis that started in 2008 have lower socioeconomic backgrounds than the single mothers who suffered through previous crises, and therefore the consequences of this crisis for children in single-parent families might be even more negative, especially in Spain.

  16. Tourism as Possible Opportunity to Address the Crisis in Italy

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Tourism today represents one of the world’s leading export commodity, accounting for global earnings of more than 200 billion Euro, about 25 per cent of total world GNP (Poirier 2000, p30, cited in Dieke, 2000. In the last 20 years, tourism has made a very important contribution to the global economy, being the fastest growing sector in terms of external revenue and new jobs. The economic and financial crisis that has affected the world economy in 2008, has led to decreasing the flow of tourists, but the tourism sector seems to be save by the new tourist that arrives from the emerging countries. In this context Italy face with a decrease in the number of tourists and a soft negative trend. The huge cultural heritage that characterize Italy and its beauty, should represent an important incentive of both, policy makers and private sector, for the relaunch of this important sector.

    2014-06-16

    Endoparasites are infrequently reported in ferrets. A cross-sectional survey was conducted to determine the prevalence of intestinal parasites in pet ferrets in southern Italy. Fresh fecal samples were randomly collected from 50 ferrets housed in pet shops or privately owned. All fecal samples were processed using the FLOTAC pellet technique to identify and count helminthic eggs/larvae and protozoan cysts/oocysts. In addition, the samples were analyzed also by the Remel XpectGiardia/Cryptosporidium immunoassay. Intestinal parasites were detected in 15 out of 50 ferrets (30%). Eggs of ancylostomids were found in 28.0% (14/50) of the animals and oocysts of Sarcocystis were detected in one ferret (2.0%). None of the samples was positive for Cryptosporidium or Giardia. To the authors' knowledge, this is the first report of sarcosporidiosis in a pet ferret in Italy.

    2001-05-01

    Recent Italian laws mandate the consideration of environmental factors in local plans, especially at the provincial level of government. The plan for the province of Cremona in northern Italy illustrates the integration of the environment in provincial-level planning. The Cremona plan was developed through an ecological planning approach that occurred from 1994 to 1998. As part of this process, the planning team designed an environmental sustainability index. This index was integrated with an environmental capability analysis. To improve the quality of the Cremona landscape, the planning team developed an ecological network. This network seeks to weave together the natural areas of the province, especially by connecting provincial parks to regional river parks throughout Lombardy. The experience of the Cremona provincial plan has implications for environmental management elsewhere in Italy, Europe, and abroad.

    2010-09-01

    Full Text Available Abstract In Italy, malaria was an endemic disease that was eradicated by the mid-20th century. This paper evaluates the prophylactic and therapeutic remedies used by folk medicine to cure malaria in Calabria (southern Italy. The data has been collected by analysing works of physicians, ethnographers, folklorists and specialists of the study of Calabrian history between the end of the 19th century and the 20th century. The data collected have allowed us to describe the most common cures used by the Calabrian people to treat malaria and the most evident symptoms of this disease, such as intermittent fever, hepato-spleenomegaly, asthenia and dropsy. This approach uncovered a heterogeneous corpus of empirical, magical and religious remedies, which the authors have investigated as evidences of past "expert medicine" and to verify their real effectiveness in the treatment of malaria.

By comparing different measures of protection adopted by national and regional authorities in Italy, the article aims to illustrate how these measures can be translated into different levels of development of broadcast media provisions for linguistic minorities. The article explores some of the effects different protective measures can have on the survival, status and economic conditions of the linguistic minority on the one hand, and the relationship with the state and the majority group on the other.

  1. Boundaries inside the body: women's sufferings in southern peasant Italy.

    Science.gov (United States)

    Pandolfi, M

    1990-06-01

    In a village of Southern Italy the secret world of women's emotions is fundamentally expressed through the body. The female body is open to events of the world and absorbs and feels their effect and defines a new identity, a minimal one. This gives rise to a symbolic anatomy, pathology, and physiology that serve to distinguish male and female worlds and to bridge inner and outer experience. These "traces" of external and extraordinary events, which in the past and in daily life have cut the secret and emotional world of women, are inscribed on the body. This body becomes a phenomenological memoir that opens a new way of interpreting distress and suffering and illness. This article represents a bridge from the interpretation of suffering and illness in Southern Italy via Gramsci and De Martino to a metacultural process of creating a polysemic and multilevel sense of self.

    Preliminary the statistical data are reported about human malignant pustule denounced in Italy in different Districts, in Lombardia and in Province of Milan. Correlatively the outbreaks and cases of haematic anthrax in animals declared in Italy, in different Districts, in Lombardia and in Province of Milan. Then the outbreaks of malignant pustule in Province of Milan are related in 1975-1977 period in the resident population where is considerable concentration of the leather manufactures. The epidemiological and microbiological researches have determined the relation among the outbreak of malignant pustule and the working of the hides imported from African Countries (Nigeria, Tanzania, Ethiopia, South Africa, Burundi-Kenya, Uganda) containing the spores of b. anthrax. The spores besides to cause infections of the workmen employed in the hide manufacture (industrial anthrax) through the effluents and solid refuses from the tanneries, are dispended upon the tiled ground and determine outbreak the haematic anthrax in the animals and agricultural coutaneus anthrax in the men.

    Full Text Available The present paper introduces a new project whose aim is to disseminate, analyse and discuss electronic literature in Italy. In the first section a general overview of the state of art of Italian electronic literature is given. We show that efforts both within academic research institutions and the publishing industry are hindered by a lack of interest and a misconception about what electronic literature is, particularly in Italy. The second section discusses two twin projects designed by Gruppo Giada, an independent research group founded in 2014: the first one is an Anthology of the History of Electronic Literature (1945-2015 (section 2.1, and the second one is an online platform (section 2.2. Finally, the conclusion underlines the goals of Gruppo Giada’s projects, given the current global landscape of the field of electronic literature.

  4. Man-induced low-frequency seismic events in Italy

    Latorre, Diana; Amato, Alessandro; Cattaneo, Marco; Carannante, Simona; Michelini, Alberto

    2014-12-01

    Unconventional seismic events in Italy are detected by scanning three years of continuous waveforms recorded by the Italian National Seismic Network. Cross correlation of signal templates with continuous seismic records has evidenced unusual events with similar low-frequency characteristics in several Italian regions. Spectral analysis and spatiotemporal distribution of these events, some of which are previously interpreted as tectonic long-period transients, suggest that they are not natural, but produced by huge cement factories. Since there are at least 57 full-cycle cement plants operating in Italy, each affecting areas of about 1250 to 2800 km2, we argue that significant portions of the Italian territory (23% to 51%) can be affected by this man-made noise. Seismic noise analyses, such as those used for microzonation or crustal structure investigations, as well as data mining techniques used to retrieve anomalous transient signals, should thus take into account this peculiar and pervasive source of seismic waves.

    Full Text Available The main purpose of this article is to analyze the possibility of implementing financial practices that, in the principles that guide them, are different from and question the functioning of most banks in capitalist societies. In particular, the article describes the ways in which credit relationships (i.e. relationships between credit institutions and their borrowers are conceived and shaped by some “alternative” banks and financial cooperatives. The findings are based on ethnographic fieldwork, including observations and in-depth interviews, focused on three financial organizations: Banca Etica (Italy, MAG6 (Italy, and La Nef (France. While striving to establish “another kind of finance”, different from the capitalistic, speculative form, these banks and financial cooperatives aim to create more cooperative and solidarity-based credit relationships.

    2016-04-01

    In this paper, the impact of future climate on pasta green water footprint (WF) was assessed. The model DSSAT CERES-Wheat was applied to simulate the production of rainfed winter durum wheat in Val d'Orcia (Central Italy), which provides the raw material for making traditional Italian pasta. The model was calibrated and validated for a 15-years period and used to estimate wheat yield and grain green WF. Further, the processing of grain for pasta making was analysed and taken into account for the calculation of the WF of final product. Then, the model was applied on future climate scenarios created with the stochastic generator LARS-WG, starting from a set of ENSEMBLES scenarios. The trend of wheat WF was analysed and the sustainability of the production of pasta in Central Italy was investigated and discussed.

    2007-01-01

    Today, preimplantation genetic diagnosis (PGD) has been greatly accepted within the framework of positive law of many European countries. Nevertheless, in other countries, such as Italy, it is forbidden by law. The ruling of the Civil Court of Cagliari which has authorized its use to a Sardinian couple, has opened, in this way, a small crack to be able to asses possible modifications to the Italian regulation on this matter. This article analyses the ruling of the Civil Court of Cagliari (Italy) from an ethical and legal perspective. The criteria which is used to analyse the legitimacy or illegitimacy of the practice of PGD is analysed. That is, on reasons which could justify or not the transfer of embryos in vitro to the woman. With this objective in mind, the Italian and Spanish normative models which regulates this controversial subject are looked at. As a conclusion, a critical evaluation of the arguments presented is made.

    Full Text Available Italy is one of the main apple producers in Europe, primarily intended for fresh consumption, both in the domestic and foreign markets. Fruit yield and quality depends on the cultivar, rootstock, and management practices, such as the fertilization and irrigation adopted in the orchard. This review aims at reporting the main apple cultivars and rootstocks, the management of fertilization and irrigation, as well as their adaptation to apple tree orchards in Italy. The programs for genetic improvement carried out in this country involved the selection of apple tree cultivars and rootstocks which enable a high fruit yield and quality, in order to meet the requirements from the consumer market. In the fertilization and irrigation management, nutrients and water are supplied in amounts next to the actual need of the plants, providing an adequate nutrition, a satisfactory yield, and high quality fruits, besides preventing, whenever possible, nutrients and water losses in the environment.

    Full Text Available An amphibian fauna from Permo-Carboniferous boundary beds is recorded for the first time in Italy. A thin fossiliferous level has been found in the Perdasdefogu Basin in southeastern Sardinia;it yields several speciments of Branchiosaurus cf."B." petrolei Gaudry 1875, often in mass mortality assemblages.Repeated mass mortality events testify to sudden changes in the environment of the basin, possibly due to seasonal variations. The finding of speciments very close to Branchiosaurus petrolei,which is a common species in the Central France basins,confirms that Sardinia at the time belonged to the same hydrographic basin of continental Europe, with no seaway in between.Furthermore, though not the primary focus of this note, we report the first discovery of the xenacanth teeth and acanthodian spines in Italy.

  15. Surfactant damages on coastal vegetation in southern Italy

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Coastal vegetation decline caused by seaspray has been reported to affect a variety of species in several countries: Australia, South of France, along the Italian Tyrrhenian coast, Spain and Tunisia. The most serious injury is due to the interaction between sea salt and surfactants, even if surfactants may cause direct damage on cell membranes. The salt uptake is enhanced by the durfactant-induced erosion of the epicuticular wax, which reduces the water surface tension. The symptoms are non-specific and consist in leaf discoloration and necrosis. In needles, necrosis begins from the apex; in leaves, from the edges. Directionality of crown damage is the main symptom for diagnosing the involvement of polluted seaspray. If an obstacle is placed between trees and sea wind, the trees do not show appreciable damage. In Italy, the tree decline caused by seaspray and surfactants has been investigated with special reference to the pinewoods of the San Rossore (Tuscany, Central Italy, or on the Tyrrhenian coastlands of Central Italy, such as the area around Castelporziano in Lazio. This research is aimed at a preliminary assessment of the extent of surfactant damage to the coastal vegetation in four regions in Southern Italy by: i field surveys and mapping of damage caused by surfactants; ii detecting the presence of surfactants on the tree crowns. The damages have been observed in a lot of zones in Apulia, Basilicata, Campania and Calabria, within 500 m inland from the sea, for a maximum length of 5500 m coastline, near the mouth of a river or stream, near the outlet of sewage canals and in any other coastal areas where the surface currents carry a surfactant load.

    Full Text Available In many areas, rainfall is the primary trigger of landslides. Determining the rainfall conditions responsible for landslide occurrence is important, and may contribute to save lives and properties. In a long-term national project for the definition of rainfall thresholds for possible landslide occurrence in Italy, and for the implementation of a national landslide warning system, we compiled a catalogue of 186 rainfall events that have resulted in 251 shallow landslides in Calabria, southern Italy, from January 1996 to September 2011. Landslides were located geographically using Google Earth®, and were given a mapping and a temporal accuracy. We used the landslide information, and sub-hourly rainfall measurements obtained from two complementary networks of rain gauges, to determine cumulated event vs. rainfall duration (ED thresholds for Calabria. For the purpose, we adopted an existing method used to prepare rainfall thresholds and to estimate their associated uncertainties in central Italy. The regional thresholds for Calabria were found nearly identical to previous ED thresholds for Calabria obtained using a reduced set of landslide information, and slightly higher than the ED thresholds obtained for central Italy. We segmented the regional catalogue of rainfall events with landslides on lithology, soil regions, rainfall zones, and seasonal periods. The number of events in each subdivision was insufficient to determine reliable thresholds, but allowed for preliminary conclusions on the role of the environmental factors on the rainfall conditions responsible for shallow landslides in Calabria. We further segmented the regional catalogue based on administrative subdivisions used for hydro-meteorological monitoring and operational flood forecasting, and we determined separate ED thresholds for the Tyrrhenian and the Ionian coasts of Calabria. We expect the ED rainfall thresholds for Calabria to be used in regional and national landslide warning

    As is well known, several Roman sources report on the existence of a town foundation ritual, inherited from the Etruscans, which allegedly included astronomical references. However, the possible existence of astronomical orientations in the layout of Roman towns has never been tackled in a systematic way. As a first step in this direction, the orientation of virtually all Roman towns in Italy (38 cities) is studied here. Non-random orientation patterns emerge from these data, aiming at further research in this field.

    This historical account of life in Italy during Fascism highlights key political and economic strategies and their impacts on the industrial and agricultural sectors, and on education and scientific research. The notable strategy - impacts cited are: the monopolization of Italian industries which resulted in the lack of internal competition and thus crippling inefficiencies, a collapse of global competitiveness and galloping inflation; and the implementation of racial policies which resulted in the loss of key participants in the field of scientific research.

    Kinematics and geo dynamics of crustal-block structures separated by compliant zones with viscoelastic rheology play an important role in defining the conditions for many deformation events such as ordinary seismic ruptures, silent and slow earthquakes and aseismic fault creep phenomena. New seismological data from the Latium-Abruzzi carbonatic platform of central Italy fit a block-tectonic modelling previously proposed for this area on the basis of structural and paleomagnetic evidences.

  8. On Architectural Practice and Arithmetic Abilities in Renaissance Italy

    Directory of Open Access Journals (Sweden)

    Giulia Ceriani Sebregondi

    2015-06-01

    Full Text Available The article examines the figure of the architect at work in Renaissance Italy, when a major change occurred in the practice of design with the spread of arithmetic. This deep scientific, technical, methodological, and cultural shift involved the image of the architect and his profession, his relationship with the patron, as well as the cultural conception of architecture. The essay, crossing disciplinary boundaries, analyses some technical aspects of architectural design in early modern Italy only marginally investigated. If proportional systems and architecture’s theoretical questions have been amply studied, the practical culture, the daily professional practice and its working tools, such as the operative arithmetic actually known to architects, have been only sporadically analysed. During the Renaissance, especially in Italy, an important development of mathematics occurred and arithmetic was clarified and simplified so to allow its diffusion, but at the same time those disciplines remained essentially despised by aristocratic and intellectual elites. What was the architects’ role in this moment of deep change? Which was the arithmetic usually employed by them in the design process? When did Hindu-Arabic numbers and fractions became familiar in the field of architecture? In the secular battle between geometry and arithmetic, which system was used in what professional cases? The essay illustrates how architects with different backgrounds responded to this change, through a comparative analysis of all the architectural drawings containing numbers and calculations made by Michelangelo Buonarroti (1475–1564, Baldassarre Peruzzi (1481–1536, and Antonio da Sangallo the Younger (1484–1546.

  9. Probabilistic seismic hazard assessment of Italy using kernel estimation methods

    Zuccolo, Elisa; Corigliano, Mirko; Lai, Carlo G.

    2013-07-01

    A representation of seismic hazard is proposed for Italy based on the zone-free approach developed by Woo (BSSA 86(2):353-362, 1996a), which is based on a kernel estimation method governed by concepts of fractal geometry and self-organized seismicity, not requiring the definition of seismogenic zoning. The purpose is to assess the influence of seismogenic zoning on the results obtained for the probabilistic seismic hazard analysis (PSHA) of Italy using the standard Cornell's method. The hazard has been estimated for outcropping rock site conditions in terms of maps and uniform hazard spectra for a selected site, with 10 % probability of exceedance in 50 years. Both spectral acceleration and spectral displacement have been considered as ground motion parameters. Differences in the results of PSHA between the two methods are compared and discussed. The analysis shows that, in areas such as Italy, characterized by a reliable earthquake catalog and in which faults are generally not easily identifiable, a zone-free approach can be considered a valuable tool to address epistemic uncertainty within a logic tree framework.

    The purpose of this study was to assess the well-being and health status of Chinese immigrant women in Italy. The subjects (mean 29.5 years) frequented the "Health Center for Foreign Women and their Children" in Bologna, Italy. Information on living conditions, biological characteristics and pregnancy or maternity was obtained through interviews of the women in the Center during normal medical visits. Data on menarche age were based on the retrospective method since all the women were in China at the onset of menarche. Social factors influencing the health and behavior of Chinese women in Italian society are discussed. The analysis on children sex ratio at birth indicates that the old cultural Chinese tradition of son preference still continues to exist. These women have achieved a socio-economic improvement and generally good health status in Italy. The difficult living conditions they faced in China are indirectly reflected in their delayed puberty (14.4 +/- 1.4 years). The delayed sexual development was probably due to the same situation of severe poverty that forced them to migrate.

    CBed bugs (Cimex lectularius) have been a common problem for humans for at least 3,500 years and in Europe their presence was endemic until the end of World War II, when infestations began to decrease. However, since the beginning of the 21st century new cases of infestations have been reported in developed countries. Many theories have been put forward to explain this change of direction, but none has been scientifically proven. The aim of this study is to provide some reports of bed bug infestations in Northern Italy (Liguria, Piedmont and Aosta valley regions) and a brief summary about their identification, clinical significance, bioecology and control. From 2008 to date, 17 bed bug infestations were identified in Northwest Italy. Knowledge about the presence and distribution of bed bugs in Italy is scanty, prior to this work only 2 studies reported the comeback of these arthropods in the Italian territory; further investigations would be necessary to better understand the current situation.

    2000-08-01

    A vast range of sources, from chronicles, hagiography and the liturgy to medical manuscripts and charters, is at our disposal for the study of health and healing in Italy between the ninth and eleventh centuries. What is needed in order to exploit this material is a methodology for the careful examination of sources in their regional, social and political context. I focus on what hagiography can contribute to the study of medicine and disease, discussing in detail two ninth-century episcopal hagiographies, the Milanese second Vita Ambrosii, and the Vita Barbati from Benevento in southern Italy. At the same time, however, I stress the limitations of studying texts in isolation, given that one region, city, or community could be simultaneously producing a number of different kinds of evidence, with possibly more than one view of sickness and healing. There is great potential for medical history in further investigation of the archaeological, liturgical, and charter evidence from early medieval Italy. The study of all surviving manuscripts from this period, not just medical words, can provide a bridge between the detailed examination of a particular text and a discussion of the wider literary and cultural traditions into which they fitted.

  14. Patient and citizen participation in health care decisions in Italy.

    2007-01-01

    In recent years there has been a growing recognition in Western healthcare systems of the importance of considering preferences of patients and the public in tailoring health services and treatment plans. The active collaboration between doctor and patient has recently been encouraged through the shared decision-making model. Aim of the present contribution is to describe the current state of patient and public participation in healthcare in Italy. First, we will briefly outline the organization of the Italian National Health Service; second, we will describe the governmental and institutional initiatives regarding participation; third, some examples of associations and initiatives promoting patient participation will be provided; forth, we will report on research projects on patient participation published in peer-reviewed journals; and finally, we will provide some examples on training activities promoting patient participation. The Italian National Health Plan and many regional and local health authorities in Italy explicitly recognize the importance of patient/citizen participation in healthcare decisions at the macro, meso and micro level of decision-making. However, application of a shared model is still at an early stage in Italy. The reported experiences have yielded positive results and have shown that particular attention should be dedicated to more disadvantaged subgroups of the population, involving patient organisations, enhancing patient/citizen knowledge and adopting approaches that take the specific context into account.

    This study assesses the impact of immigration in Friuli Venezia Giulia, a region of northeastern Italy, on the epidemiological features of hemoglobin patterns and on prothrombotic and trisomy risk in pregnancy for patients of non-Italian origin. This study follows a series of studies on the incidence of thalassemia and other hemoglobinopathies with reduced globin chain synthesis, that were performed during the postwar (1939-45) period in Friuli Venezia Giulia following immigration into the region from Istria and Sardinia (regions of northern and central Italy). Current data show that today's constantly growing immigration into the region differs from previous decades, in terms of origin and quantity of migrants, who mainly come from third world countries. This has a significant impact on health care issues, and more specifically on prospective health screening for foreigners. The authors conclude that scholastic education and hospital services, either public or private, and voluntary associations, may contribute to solving the problem, but only in terms of training and organization, for non-European Union citizens arriving in northern Italy and neighboring areas, especially those from Africa, Asia, Latin America, and eastern Europe.

  16. Crustal and deep seismicity in Italy (30 years after

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

    1981-01-01

    Labor force trends in Italy during the 1970s are analyzed, with particular reference to labor force participation by women. Migration trends, including migration from Italy to the rest of Europe, from developing countries to Italy, and from the south to the north of Italy, are reviewed. Factors affecting female labor force participation that are considered include the depression, the austerity program, inflation, automation in factories, computerization in offices, stratification of the labor force, decentralization, domestic labor, and the feminist movement. The effect of these factors on women's attitude toward reproduction is also considered.

  20. A Gum-Tree Exile: Randolph Bedford in Italy

    Directory of Open Access Journals (Sweden)

    Lucy Jane Sussex

    2012-11-01

    Full Text Available Randolph Bedford (1868–1941 was an Australian journalist, politician and novelist, a lifelong socialist despite making a small fortune from mining. He was among the ‘brain drain’ of Australians at the turn of last century, who hoped to emulate Melba’s success in England. Many of his contemporaries, such as Henry Lawson, experienced disillusion and poverty, and returned home. Bedford differed in his versatility, and also his profound rejection of the British Empire. He could not sell his novels initially, nor his speculations to British investors, but was able to put his mining experience to use in Italy. There he became one of the first Australians to fall in love with the country. His attraction to Italy was partly aesthetic, its artistic glories, but also because it reinforced his sentimental Australian nationalism. He saw similarities in landscape, and also in climate. He wrote despatches back to the Bulletin called ‘Explorations in Civilization’, which became a book in 1916. The subtitle was ‘An Australian in Exile’, reversing the ‘Exiles We’, of the first settlers, with their nostalgia for Britain. In contrast, Bedford saw nothing good in London and the Empire. He disliked it upon first sight, and his irreverence and socialist sympathies had no place in the conservative British investment milieu. Bedford would sell two novels in Britain, via Henry Lawson (whom he helped in London and his literary agent J. B. Pinker. But he returned home, certain expatriate life was not for him, and devoted his energies to Australia. His real success was in Explorations in Civilization, superb travel-writing, perhaps his best work. It shows his love for his country being reinforced through the perceived similarities between it and Italy, a second homeland for him. He even paid its people his highest compliment: that they were his preferred settlers for Australia.

  1. Hepatitis E Virus Circulation in Italy: Phylogenetic and Evolutionary Analysis

    Directory of Open Access Journals (Sweden)

    Montesano

    2016-03-01

    Full Text Available Background Hepatitis E virus (HEV, a major cause of acute viral hepatitis in developing countries, has been classified into four main genotypes and a number of subtypes. New genotypes have been recently identified in various mammals, including HEV genotype 3, which has a worldwide distribution. It is widespread among pigs in developed countries. Objectives This study investigated the genetic diversity of HEV among humans and swine in Italy. The date of origin and the demographic history of the HEV were also estimated. Materials and Methods A total of 327 HEV sequences of swine and humans from Italy were downloaded from the national centre for biotechnology information. Three different data sets were constructed. The first and the second data set were used to confirm the genotype of the sequences analyzed. The third data set was used to estimate the mean evolutionary rate and to determine the time-scaled phylogeny and demographic history. Results The Bayesian maximum clade credibility tree and the time of the most common recent ancestor estimates showed that the root of the tree dated back to the year 1907 (95% HPD: 1811 - 1975. Two main clades were found, divided into two subclades. Skyline plot analysis, performed separately for human and swine sequences, demonstrated the presence of a bottleneck only in the skyline plot from the swine sequences. Selective pressure analysis revealed only negatively selected sites. Conclusions This study provides support for the hypothesis that humans are probably infected after contact with swine sources. The findings emphasize the importance of checking the country of origin of swine and of improving sanitary control measures from the veterinary standpoint to prevent the spread of HEV infection in Italy.

    This volume contains the invited and contributed papers presented at the 14th Conference on Theoretical Nuclear Physics in Italy held in Cortona, Italy, from 29-31 October, 2013. The meeting was held at the Palazzone, an elegant Renaissance Villa, commissioned by the Cardinal Silvio Passerini (1469-1529), Bishop of Cortona, and presently owned by the Scuola Normale Superiore di Pisa. The aim of this biennial Conference is to bring together Italian theorists working in various fields of nuclear physics to discuss their latest results and confront their points of view in a lively and informal way. This offers the opportunity to stimulate new ideas and promote collaborations between different research groups. The Conference was attended by 46 participants, coming from 13 Italian Universities and 11 Laboratories and Sezioni of the Istituto Nazionale di Fisica Nucleare - INFN. The program of the conference, prepared by the Organizing Committee (Ignazio Bombaci, Aldo Covello, Laura Elisa Marcucci and Sergio Rosati) focused on the following main topics: Few-Nucleon Systems Nuclear Structure Nuclear Matter and Nuclear Dynamics Relativistic Heavy Ion Collisions and Quark-Gluon Plasma Nuclear Astrophysics Nuclear Physics with Electroweak Probes Structure of Hadrons and Hadronic Matter. In the last session of the Conference there were two invited review talks related to experimental activities of great current interest. Giacomo De Angelis from the Laboratori Nazionali di Legnaro spoke about the INFN SPES radioactive ion beam project. Sara Pirrone, INFN Sezione di Catania, gave a talk on the symmetry energy and isospin physics with the CHIMERA detector. Finally, Mauro Taiuti (Università di Genova), National Coordinator of the INFN-CSN3 (Nuclear Physics Experiments), reported on the present status and future challenges of experimental nuclear physics in Italy. We gratefully acknowledge the financial support of INFN who helped make the conference possible. I Bombaci, A Covello

    Full Text Available A serosurvey has been conducted in Northern and Central Italy to investigate the presence in humans of antibodies against zoonotic Babesia and Theileria species. The study focused on a total of 432 volunteers, of which 290 were persistently exposed to tick bites because of their jobs (forester employees, livestock keepers, veterinary practitioners, farmers and hunters and 142 resident in the same area less frequently exposed. An indirect fluorescent antibody test (IFAT for humans was used to detect antibodies to Babesia microti, IFAT tests for veterinary use were modified to detect reactivity to Babesia bovis, Babesia canis and Theileria equi. A laboratory-derived ELISA was employed to detect antibodies to Babesia divergens. Both reactive and 10 negative sera were analysed against plasmodial antigens to evaluate possible aspecificity. A high reactivity to piroplasm antigens was found, showing significant difference between the sera of the two groups of volunteers (24% vs 7.0%; p<0.001. No cross-reactivity was observed, while each professional group showed reactivity that would fit with the professional risk exposure. In particular, a high reactivity to B. microti and B. divergens antigens was observed in foresters and hunters (32% and 12%, respectively. This is the first report on the human seroreactivity to piroplasms in Italy; it also provides additional epidemiological information on these tick-borne zoonoses in Europe. Our findings suggest the possible occurrence of piroplasm infections in Italy and alert physicians to consider these otherwise neglected parasitic diseases when dealing with any febrile illness, especially in subjects exposed to tick bites.

  4. Detention and incompatibility of HIV patients in Italy

    Full Text Available In Italy, Law 231/99 and subsequent amendments standardize the conditions allowing or not a HIV positive inmate to remain in jail. Currently such clinical conditions are not automatically associated with the decline of preventive detention and the Court evaluates the incompatibility with detention on the basis of two additional and independent criteria. We have been observing the tendency by jailed HIV-positive patients to manipulate the disease state believing that the rules of incompatibility with the prison system are always applied. The management of HIV positive patients in jail involves significant sanitary and relational efforts, particularly for those suffering AIDS and/or with severe immunodeficiency.

    2016-01-01

    We outline a realistic energy transition roadmap for Italy, in which the whole energy demand is met by electricity generated by low cost renewable energy technologies, namely solar photovoltaic, wind and hydroelectric power. We assess the amount of extra power and storage capacity to be installed along with costs, return on investment and payback time. Based on cost, renewable nature and scalability, storage in energy dense polysaccharides enzymatically synthesized from carbon dioxide, water and surplus electricity is proposed to meet the significant storage requirements.

  6. PAKISTANIS IN ITALY: THE DISENCHANTMENTS OF “LIVING TRANSNATIONALLY”

    Directory of Open Access Journals (Sweden)

    Ali Nobil Ahmad

    2010-12-01

    Full Text Available This article begins with a constructive critique of theories on immigration and highlights the problems implicit in the suppositions of the social network/capital theory and in research on ethnic economies and “transnationalism”. From these theories, the author adopts the postulates that he considers to be most useful for applying to the analysis of the Pakistani diaspora in Italy, demystifying the old theories and calling for greater focus on the economic policy of the networks of emigrants that actually exist. He believes that diasporas act as organisms that are linked in space and time, and which progressively mutate. He goes on to observe how the relatively weak links that today’s emigrants maintain with their country of origin contrast with the undoubtedly stronger links that previous generations of Pakistani emigrants maintained in the United Kingdom; thus he suggests that we should break the reductionist chain of association that automatically attributes greater levels of transnationalism to the new emigration. In this respect, Nobil Ahmad notes that political and economic factors are sometimes more important than technology when it comes to shaping the intensity of the connections sustained between the issuing and welcoming societies in the migration process. Pakistanis in Italy have spent most of their energy working or standing up for their political rights in Europe rather than travelling or sending money home. Likewise, he notes that it is not always true that social networks necessarily carry out the function of mediation of emigration and reducing its costs; on the contrary, in the Mediterranean, the prominence of agenti in emigration networks suggests that we should be sensitive to the importance of mercantilised networks and to the commercial transactions between emigrants and autochthonous citizens. Finally, he calls attention to the individual experience of immigrants who have thrived businesswise, and whose experiences

  7. Structural Changes and Dairy Chain Efficiency in Italy

    Directory of Open Access Journals (Sweden)

    Franco Rosa

    2015-07-01

    Full Text Available The dairy chain in Italy experienced substantial structural changes during the past years. Since the introduction of milk quotas in 1984, structural changes caused by consistent reduction of dairy farms, growing brand concentration at wholesale level, and diffusion of private labels at retail level may have altered the competitive market conditions, with increasing price asymmetry and inefficiencies in price transmission. We tested this hypothesis using the McCorriston and Sheldon’s successive oligopoly model, and we gave evidences of altered price transmission and consumer’s surplus distribution along the vertical chain in the examined period.

    In spite of the fact that in the majority of cases the most important radon source is the soil and the rock beneath the house, no large scale survey of soil radon has ever been made in Italy. In this paper the results of a large scale survey of soil radon are presented from measurements made in hundreds of different sites in Latium and Campania. For several locations, results of measurements gathered for different years are described and up-dated. As a pilot project for indoor radon survey monthly variations of radon concentrations in typical houses have been investigated. (author).

    Long wait times for access to Nuclear Magnetic resonance imaging (MRI) examinations are a concern and for this reason the project "Appropriateness of referrals for MRI examinations" has been launched in Latium (Italy). The aim of this preliminary study was to describe the main characteristics of MRI referrals in the region. Findings highlight a large variation in referral rates across the region, with 80% of MRI referrals being ordered by general practitioners and family pediatricians. The latter points to the possibility of inappropriate referrals for MRI imaging in Latium.

In accordance with the objectives of the FAO treaty on plant genetic resources (ITPGRFA, these laws have emerged as one of the most interesting institutional attempts at Italian and European level towards enhancing and protecting agricultural biodiversity. A description of the regional laws and their implementation highlights the importance of supporting farming systems that are close relationship with the territory and local communities, creating sufficient juridical space for the varieties that are not part of the ‘formal’ seed system.

    Suhadolc, P.; Panza, G.F. (Istituto di Geodesia e Geofisica, Universita di Trieste (Italy))

    Seismicity patterns and precursors before the 11/23/80 Irpinia, Italy, earthquake are searched for in the ENEL-CNEN Italian earthquake catalogue. By subdividing the region into several seismogenetic areas, some well defined seismicity features are found, which might be taken as precursory to the 1980 event. Features already pointed out as precursory in the literature are also contained in the space-time seismicity pattern. Prediction of approximate location where the main rupture is bound to occur is permitted, by grouping the seismogenetic areas into a seismically homogeneous region.

A~model based on the affinity laws is used to simulate the behavior of the Casale pumping station where variable speed pumps (VSPs are installed. Quadratic and cubic polynomial curves are used to fit the pump data given by the affinity laws. Such curves can be used to predict the efficiency when the functioning conditions change. The relationship between the variation in the rotation speed and the efficiency is also derived.

    The aims of this study were to determine natural infections by Anaplasma phagocytophilum/Anaplasma platys, Bartonella henselae, Ehrlichia canis, Leishmania infantum, Rickettsia spp., Babesia spp., and Hepatozoon spp. by molecular methods in ticks (n=91) removed from dogs with clinical signs and laboratory abnormalities compatible with tick-borne diseases (n=22) living in Italy and to assess the distribution and species of ticks encountered. Ticks from dogs living in southern Italy were all identified as Rhipicephalus sanguineus (n=25), ticks from central Italy included Rh. sanguineus (n=8) and Ixodes ricinus (n=9), ticks from northern Italy included Rh. sanguineus (n=45), Dermacentor marginatus (n=3), and one I. ricinus. Leishmania infantum, Rickettsia spp., and Babesia canis were the only pathogens detected in 7 (8%), 4 (4%), and 2 (2%) out of 91 ticks, respectively. L. infantum was detected in I. ricinus from central Italy and in Rh. sanguineus from northern and central Italy. Rickettsia conorii and Ri. massiliae were detected in Rh. sanguineus ticks from central and southern Italy (Sicily), respectively. Bab. canis was detected in D. marginatus ticks from northern Italy.

    2016-04-01

    According to the satellite cloud anomaly appeared over eastern Italy on 21-23 April 2012, we predicted the M6.0 quake occurred in north Italy successfully. Here checked the satellite images in 2011-2013 in Italy, and 21 cloud anomalies were found. Their possible correlation with earthquakes bigger than M4.7 which located in Italy main fault systems was statistically examined by assuming various lead times. The result shows that when the leading time interval is set to 23≤ΔT≤45 days, 8 of the 10 quakes were preceded by cloud anomalies. Poisson random test shows that AAR (anomaly appearance rate) and EOR (EQ occurrence rate) is much higher than the values by chance. This study proved the relation between cloud anomaly and earthquake in Italy. With this method, we found that L'Aquila earthquake can also be predicted according to cloud anomaly.

  14. The epidemiology of Varicella Zoster Virus infection in Italy

    Directory of Open Access Journals (Sweden)

    Ciofi degli Atti Marta L

    2008-10-01

    Full Text Available Abstract Background The epidemiological importance of varicella and zoster and the availability of an efficacious and safe vaccine have led to an important international debate regarding the suitability of mass vaccination. The objective of the study was to describe the epidemiology of varicella and zoster in Italy and to determine whether there have been changes with respect to observations provided by an analogous study conducted 8 years ago, in order to define the most appropriate vaccination strategy. Methods A number of data sources were evaluated, a cross-sectional population-based seroprevalence study was conducted on samples collected in 2004, and the results were compared with data obtained in 1996. Results The data from active and passive surveillance systems confirm that varicella is a widespread infectious disease which mainly affects children. VZV seroprevalence did not substantially differ from that found in the previous study. The sero-epidemiological profile in Italy is different from that in other European countries. In particular, the percentage of susceptible adolescents is at least nearly twice as high as in other European countries and in the age group 20–39 yrs, approximately 9% of individuals are susceptible to VZV. Conclusion The results of this study can contribute to evaluating the options for varicella vaccination. It is possible that in a few years, in all Italian Regions, there will exist the conditions necessary for implementing a mass vaccination campaign and that the large-scale availability of MMRV tetravalent vaccines will facilitate mass vaccination.

  15. [The position of nephrology in regional health programs in Italy].

    Science.gov (United States)

    Susi, Alessandra

    2010-01-01

    Regional health policies are acquiring remarkable importance in the allocation of healthcare resources, both human and financial. The importance of playing a prominent role in national and regional policy-making for healthcare professionals derives from the need to render the interventions of health policy more suitable to different territories. A review of all official regional healthcare plans approved in Italy until February 2009 has been carried out with the aim of recording the level of inclusion of nephrology in regional healthcare programming. The attention to kidney diseases has been delineated according to six levels of relevance: (i) the mere inclusion of nephrology in the plan, (ii) the level of priority of nephrology among other areas of intervention, (iii) the presence of new dedicated programs, (iv) the reinforcement of ongoing programs, (v) the allocation of specific resources, and (vi) the existence of nephrology networks. Nephrology does not turn out to be one of the priorities of intervention within the regional frameworks, with the exception of some regions which were found to be particularly sensitive to issues of outpatient care. Ad hoc measures for (i) the allocation of resources, (ii) the activation and (iii) the reinforcement of specific networks or programs were documented in a few cases. Nephrology is still too scarcely included in regional programming, considering the prevalence of chronic kidney disease in Italy. It is necessary that regional representatives of the discipline participate in healthcare planning to guarantee essential qualitative levels of healthcare for chronic kidney disease.

    The analysis of extreme precipitation has always been included among most relevant hydrological applications because of the several important activities linked to the availability of tools for the estimation of extreme rainfall quantiles. These activities include the design of hydraulic civil structures and the evaluation and management of hydraulic and hydrological risk. In this study a frequency analysis of annual maxima precipitation measurements has been carried out for the area of Sicily (Italy). A typical hierarchical regional approach has been adopted for the parameter estimation procedure based on the L-moments method. The identification of homogeneous regions within the procedure has been pursued with a data driven procedure constituted by a principal component analysis of an ensemble of selected auxiliary variables, and a K-means cluster analysis algorithm. Auxiliary variables comprise meteo-climatic information and a representation of the average seasonal distribution of intense events. Results have been evaluated by means of a Monte Carlo experiment based on the comparison between at-site and regional fitted frequency distributions. Moreover, results have been compared with previous analyses performed for the same area. The study provides an updated tool for the modelling of extreme precipitation for the area of Sicily (Italy), with different features respect to previous tools both in terms of definition of homogeneous zones and in terms of parameters of the frequency distribution. Meteo-climatic information and the seasonality of extreme events retrieved from the dataset has been proficuously exploited in the analysis.

    Full Text Available INTRODUCTION: The European Regional Office of the World Health Organization developed a strategic approach to stop the indigenous transmission of measles in its 53 Member States by 2015. In Italy, laboratory surveillance activity is implemented by the National Reference Laboratory for Measles and Rubella at the Italian National Institute of Health (Istituto Superiore di Sanità, Rome. The role of the National Reference Laboratory is to strengthen surveillance systems through rigorous case investigation and laboratory confirmation of suspected sporadic cases and outbreaks. Genetic characterization of wild-type measles virus is an essential component of the laboratory-based surveillance. This study describes the molecular characterization of measles virus strains isolated during 2010. METHODS: Dried blood spots, urine and oral fluid samples were collected from patients with a suspected measles infection. Serological tests were performed on capillary blood, and viral detection was performed on urine and oral fluid samples through molecular assay. Positive samples were sequenced and phylogenetically analysed. RESULTS AND DISCUSSION: The phylogenetic analysis showed a co-circulation of genotypes D4 and D8, and sporadic cases associated to genotypes D9 and B3. Then, molecular epidemiology of measles cases permitted to establish that D4 and D8 were the endemic genotypes in Italy during 2010.

    Full Text Available On 6 April 2009 an earthquake of magnitude 6.3 occurred in L'Aquila city, Italy. In the city center and surrounding villages many masonry and reinforced concrete (RC buildings were heavily damaged or collapsed. After the earthquake, the inspection carried out in the region provided relevant results concerning the quality of the materials, method of construction and the performance of the structures. The region was initially inhabited in the 13th century and has many historic structures. The main structural materials are unreinforced masonry (URM composed of rubble stone, brick, and hollow clay tile. Masonry units suffered the worst damage. Wood flooring systems and corrugated steel roofs are common in URM buildings. Moreover, unconfined gable walls, excessive wall thicknesses without connection with each other are among the most common deficiencies of poorly constructed masonry structures. These walls caused an increase in earthquake loads. The quality of the materials and the construction were not in accordance with the standards. On the other hand, several modern, non-ductile concrete frame buildings have collapsed. Poor concrete quality and poor reinforcement detailing caused damage in reinforced concrete structures. Furthermore, many structural deficiencies such as non-ductile detailing, strong beams-weak columns and were commonly observed. In this paper, reasons why the buildings were damaged in the 6 April 2009 earthquake in L'Aquila, Italy are given. Some suggestions are made to prevent such disasters in the future.

    Little information is available on the occurrence of endoparasites in pet guinea pigs (Cavia porcellus). The purpose of this study was to evaluate the prevalence of intestinal parasites in cavies kept as pets in southern Italy. Fresh fecal samples were randomly collected from 60 guinea pigs housed in pet shops or privately owned. All fecal samples were processed using the FLOTAC pellet technique to identify and count helminthic eggs/larvae and protozoan cysts/oocysts. In addition, the specimens were analyzed also by the Remel Xpect® Giardia/Cryptosporidium immunoassay. Intestinal parasites were detected in 19 out of 60 guinea pigs (31.7 %). Paraspidodera uncinata eggs were found in 13.3 % (8/60) of the rodents examined, Nippostrongylus-like eggs in 10 % (6/60), and finally Eimeria caviae oocysts were found in 10 % (6/60) of the animals. In one case, both E. caviae oocysts and P. uncinata eggs were found. None of the samples was positive for Cryptosporidium or Giardia. To the authors' knowledge, this is the first survey of endoparasites in pet guinea pigs in Italy.

    Full Text Available Bats are natural reservoirs for many mammalian coronaviruses, which have received renewed interest after the discovery of the severe acute respiratory syndrome (SARS and the Middle East respiratory syndrome (MERS CoV in humans. This study describes the identification and molecular characterization of alphacoronaviruses and betacoronaviruses in bats in Italy, from 2010 to 2012. Sixty-nine faecal samples and 126 carcasses were tested using pan-coronavirus RT-PCR. Coronavirus RNAs were detected in seven faecal samples and nine carcasses. A phylogenetic analysis of RNA-dependent RNA polymerase sequence fragments aided in identifying two alphacoronaviruses from Kuhl’s pipistrelle (Pipistrellus kuhlii, three clade 2b betacoronaviruses from lesser horseshoe bats (Rhinolophus hipposideros, and 10 clade 2c betacoronaviruses from Kuhl’s pipistrelle, common noctule (Nyctalus noctula, and Savi’s pipistrelle (Hypsugo savii. This study fills a substantive gap in the knowledge on bat-CoV ecology in Italy, and extends the current knowledge on clade 2c betacoronaviruses with new sequences obtained from bats that have not been previously described as hosts of these viruses.

    2008-01-01

    Full Text Available Introduction: the antibiotic usage in Italy is above the European average. From several years the Campania was the first Italian region in terms of antimicrobial consumption. Aim: to evaluate antibiotic utilisation in primary health care in Campania, a region of approximately 5.7 million inhabitants in the south of Italy. Method: we collected, from an electronic database, all prescription drugs reimbursed in 2005. The cohort was defined as the population of subjects receiving at least one prescription of any antimicrobial agent for systemic use, classified according to their therapeutic role using Anatomic Therapeutic Chemical (ATC classification. Drugs cost and consumption were quantified using National Health Service (NHS prospective and Defined Daily Dose system (DDD respectively. All costs were expressed in Euro 2005. Results: antiinfectives agents (ATC J was the second class of drugs in terms of cost, representing 16.1% of the regional drug expenditure. Their consumption were 33 DDD/1000 inhabitants/day. Stratifying by age antibiotic use was highest in children and elderly subjects. Penicillins, macrolides and cephalosporins were the most prescribed antibiotic classes in all age groups. Discussion: despite guidelines introduced to limit the prescription of parenteral antibiotics to the patients who are most likely to benefit from it, they were mostly prescribed. This represented a serious problem for the development of drug-resistant bacteria.

  3. A Behavioural Model of E-Banking Usage in Italy

    2013-06-01

    Full Text Available E‐banking is defined as the automated delivery of new and traditional banking products and services directly to customers through electronic, interactive communication channels. “Pure online” banks are characterized by the absence of physical windows and front‐office personnel. Traditional banks are still integrating traditional distribution channels with online ones; the scenario is therefore still evolving over time. Despite the intrinsic potentialities, Italy is far from being a leader in the usage of innovative online instruments in the banking system and will struggle with new innovation waves. In this paper, we measure the potential effective ebanking usage. Furthermore, we investigate the behaviour of users and adopters, identifying the major causes influencing satisfaction and usage and the impact of these different causes on the intensity of utilization. The analysis is based on a panel of 495 real users, thus allowing the profiling of the Italian adopter to discover the causes of usage and outline strategies for the growth of e‐banking services in Italy.

    2014-05-01

    Just after the Mw 6.2 earthquake that hit L'Aquila, on April 6 2009, the Civil Protection nominated an International Commission on Earthquake Forecasting (ICEF) that paved the way to the development of the Operational Earthquake Forecasting (OEF), defined as the "procedures for gathering and disseminating authoritative information about the time dependence of seismic hazards to help communities prepare for potentially destructive earthquakes". In this paper we introduce the first official OEF system in Italy that has been developed by the new-born Centro di Pericolosità Sismica at the Istituto Nazionale di Geofisica e Vulcanologia. The system provides every day an update of the weekly probabilities of ground shaking over the whole Italian territory. In this presentation, we describe in detail the philosophy behind the system, the scientific details, and the output format that has been preliminary defined in agreement with Civil Protection. To our knowledge, this is the first operational system that fully satisfies the ICEF guidelines. Probably, the most sensitive issue is related to the communication of such a kind of message to the population. Acknowledging this inherent difficulty, in agreement with Civil Protection we are planning pilot tests to be carried out in few selected areas in Italy; the purpose of such tests is to check the effectiveness of the message and to receive feedbacks.

  5. Gender equality and equal opportunity mechanisms in Italy

    2007-01-01

    Full Text Available As a country of Southern European mentality Italy may be taken as the nearest-to-the-Balkans model of the gender equality mechanisms and necessity of their existence. Italy also might be taken as a model of domain and methods of functioning of the gender equality mechanisms as well as their connections with the EU development funds. Besides the Italian Ministry for Rights and Equal opportunities and the National Committee, the attention was paid to the whole range of local mechanisms and legal regulations dealing with advancement of women’s employment and counteracting discrimination on the labor market. In the text are analyzed through the five chapters the Italian mechanisms/institutions for gender equality as located within the European institutional environment but also within the context of Italian recent history of struggle against gender based discrimination. It was stressed that the essence of the accumulated European institutional wisdom is in diversity of the gender equality bodies rather then in their uniformity. Although the Italian mechanisms for gender equality are part of the European institutional environment their aim is to meet the internal needs for advancement of gender equality. Besides, the mechanisms also meet the demands of the international standards comprised in the documents issued by the UN and the EU. In European countries these mechanisms are frequently established and function in the domains of the labor and employment regulations, but also are located within the human rights portfolios while somewhere are connected with the minority rights and equal opportunity implementation.

    Assessing couple relationships across diverse languages and cultures has important implications for both clinical intervention and prevention. This is especially true for nontraditional relationships potentially subject to various expressions of negative societal evaluation or bias. Few empirically validated measures of relationship functioning have been developed for cross-cultural applications, and none have been examined for their psychometric sufficiency for evaluating same-sex couples across different languages and cultures. The current study examined the psychometric properties of an Italian translation of the Marital Satisfaction Inventory - Revised (MSI-R), a 150-item 13-scale measure of couple relationship functioning, for its use in assessing the intimate relationships of gay and lesbian couples in Italy. Results for these couples were compared to data from heterosexual married and unmarried cohabiting couples from the same geographical region, as well as to previously published data for gay, lesbian, and unmarried heterosexual couples from the United States. Findings suggest that, despite unique societal pressures confronting Italian same-sex couples, these relationships appear resilient and fare well both overall and in specific domains of functioning compared to heterosexual couples both in Italy and the United States.

    2016-04-01

    Two stratigraphic sections located in the Latium-Abruzzi (Monte Porchio, Central Apennines, Central Italy) and in the Apulian carbonate platform (S. Cesarea-Torre Tiggiano, Salento, Southern Italy) were measured and sampled to document the sedimentological characteristic and the faunistic assemblages of Middle Eocene seagrass deposits. The faunistic assemblages are dominated by porcellaneous foraminifera Orbitolites, Alveolina, Idalina, Spiroloculina, Quinqueloculina, Triloculina and abundant hooked-shaped gypsinids, associated with hooked red algae and green algae Halimeda. Fabiania, rotaliids and textulariids as well as nummulitids are subordinated. The samples were assigned to Lutetian (SBZ13-16) according to the occurrence of Nummulites cf. lehneri, Alveolina ex. gr. elliptica, Idalina berthelini, Orbitolites complanatus, Slovenites decastroi and Medocia blayensis. At Santa Cesarea reticulate nummulites occur in association with Alveolina spp. and Halkyardia minima marking the lower Bartonian (SBZ17). Three main facies associations have been recognised: I) larger porcellaneous foraminiferal grainstones with orbitolitids and alveolinids deposited into high-energy shallow-water settings influenced by wave processes that reworked the sediments associated with a seagrass; II) grainstone to packstone with small porcellaneous foraminifera and abundant permanently-attached gypsinids deposited in a more protected (e.g., small embayment) in situ vegetated environment; III) bioclastic packstone with parautochthonous material reworked from the seagrass by rip currents and accumulated into rip channels in a slightly deeper environment. The biotic assemblages suggest that the depositional environment is consistent with tropical to subtropical vegetated environments within oligotrophic conditions.

  8. Regional sinkhole susceptibility maps: The Latium Region case (central Italy)

    2012-04-01

    Several and frequent studies were internationally presented about landslide susceptibility, meanwhile in literature is missing a broad diffusion of studies regarding sinkhole susceptibility. That's why sinkhole recurrence depends on several geological conditions related to specific geological and hydrogeological context (sinkhole prone area) that vary case by case. Notwithstanding this regionalization problem of sinkhole recurrence, in the central Appenine sedimentary basins (Italy) a certain number of geological, geomorphologic and hydrogeological conditions (sinkhole predisposing issues) can be considered in common between the surveyed sinkholes. Eventually this could be compared with similar geological conditions and sinkhole occurrence in the rest of Italy or in other countries. In this case study is presented a probabilistic approach regarding the Latium Region deriving from the comparison between the regional sinkhole inventory realized during a precedent project and the dataset of the new Hydrogeological Map of Latium Region (scale 1:100.000). Indexed elements, chosen because associated to the majority of sinkhole phenomena, are: outcropping lithologies, water table depth, main faults (even if buried), hydrothermal springs, land use and the epicentres of recent earthquakes. These indexed elements were weighted and combined in a matrix which preliminary result is the sinkhole susceptibility map of Latium Region. When definitively validated, this approach could be suitable for local authorities to planning more targeted studies in major hazard areas.

  9. Medical humanities in healthcare education in Italy: a literature review

    Full Text Available OBJECTIVE. The introduction of medical humanities (MH in undergraduate medical education in Italy has been an issue of debate since the 90's and few years later it was extended to other healthcare degrees. The aims of this Italian literature review, after considering the international scene, are: to evaluate the extent to which the interest in this subject has gradually developed throughout the country; which professional groups have contributed to the debate; to identify which theoretical constructs led to the introduction of MH in undergraduate medical education; to identify whether a clear and shared definition of MH exists in Italian literature; to verify what kinds of MH experiences have been accomplished in Italy. MATERIALS AND METHODS. A comprehensive literature search was conducted, including electronic databases, bibliographies, manual sorting of articles in paper format, congress proceedings. RESULTS. The analysis of the chosen articles underlines that, however limited, Italian literature does not present a very different picture from the international scene. It emerges that teaching MH is believed to be an important feature in undergraduate education of healthcare professionals who intend to propose a bio-psychological-social approach to care, in spite of the difficulty to measure its short and long term effectiveness. The lack of a multidisciplinary, multi-professional approach is also evident. CONCLUSION. Further research aiming to implement the quantity and quality of MH studies in the curricula of undergraduate healthcare education is desirable.

    The identification of HHV-8 has opened the way for numerous epidemiological studies aimed at determining both the prevalence of HHV-8 in various sub-groups of the population (affected or not by KS) and at identifying possible cofactors necessary for the development of KS. We set up a study to evaluate the prevalence of HHV-8 in the South of Italy in KS cases, hospital patients and blood donors and to verify the role of immunosuppression in KS. In KS patients the prevalence of lytic and latent antigens were both 91% (29 positive cases). Lytic and latent antigens have prevalence rates of 20% and 15% respectively in hospital patients. In the donor group the rates were 16% for lytic antigens and 2% for latent antigens. The most recurrent chronic pathology in KS patients was cardiopathy (5 cases). The pathological case histories report 4 cases of Herpes Zoster, 6 of diabetes, one case of hepatitis C who had also had gonorrea. There was also a case, negative to HHV-8, who had had malaria after residing for three years in Oristano in Sardinia (a zone with high endemic malaria). Our study confirms that in Southern Italy there are relatively high prevalences of HHV-8 both in the general population and in blood donors and that immunodysregulation may be involved in the pathogenesis of KS. Other studies are necessary to confirm the sexual transmission of the HHV-8 virus and to better understand the natural history of HHV-8 infection.

    A cutaneous nodule associated with Neospora caninum infection was diagnosed in a 5-year-old male Bernese cattle dog from Italy. The ulcerative lesion was 2-3 cm wide located in the skin of the tarsal region. Haematological values were normal and the dog did not show any neurological abnormalities. The dermal lesion consisted of a diffuse necrotic dermatitis with a dense infiltrate of mostly neutrophils and macrophages, surrounded by a fibrous wall. Histological sections revealed numerous tachyzoites of N. caninum scattered throughout the tissue. Diagnosis was confirmed both by immunohistochemical staining and electron microscopic examination. The dog had a 1:640 IFAT titre to N. caninum. Four weeks after surgical excision new subcutaneous nodules reappeared. The cutaneous lesions resolved following 21 days of therapy with clindamycin hydrochloride. These observations demonstrate the presence of N. caninum in Italy and confirm that neosporosis should be considered in the differential diagnosis of pyogranulomatous dermatitis in dogs. Clindamycin may be an effective treatment for cutaneous neosporosis.

    2016-12-01

    Full Text Available This article analyses the parody procedures employed by the Marquis de Sade in descriptions of works of art (ekphrasis that are found in the little-known Voyage d’Italie, account of a trip to Italy that the author made in 1775 to escape the persecution of French police. Unpublished until the nineteen sixties, nor taken into account in critical studies, this travel diary provides precious insight into many philosophical and aesthetic categories that were commonly discussed in debates in the pre-Revolutionary period. Following a substantial but fundamental section on the meagre literature about the Voyage, this essay focuses on only a few passages concerning ekphrasis in Sade’s work, enough to show how parody and satire were essential rhetorical conditions in order for the author to overturn the transcendent meaning of the works of arts as it was imposed by the Christian/Neo-platonic aesthetic tradition, which was still ruling on the intellectual milieu of the eighteenth-century grandtouristes. In accordance with the most radical tendencies of the Enlightenment - Diderot’s materialism and Shaftesbury’s philosophy of “wit” provide a good example -, in his literary debut Sade offers an ingenious and inventive framework that is well ahead of his times and, therefore, deserves further examination.

  13. Language and Identities: The Exceptional Normality of Italy

    Directory of Open Access Journals (Sweden)

    John J. Kinder

    2008-10-01

    Full Text Available Language issues loom large in current debates on Italian identity/identities, indigenous minorities in Italy and, of course, immigration. While the context of language debates in early 21st century Italy presents new realities and challenges, the fundamental issues are the same as those originally defined by the first European language planner, Dante, and reworked by successive theorists. The debates turn on exclusions and inclusions, on levels of multiple identities, on understandings of otherness. It is no accident that language is at once as a provocation for debates on identity and a metaphor of those debates, for the tensions that run through the debates lie at the heart of language itself. All cultures have a narrative that explains diversity among languages and cultures, either as the result of a mistake or as divine punishment. The Biblical accounts of Creation, Babel and Pentecost provide the framework for European understandings of language diversity. These accounts capture the paradoxical nature of human language, which characterizes us a species and is a tool for building unity between persons and groups, but is, by its nature, always and inevitably an expression of diversity, in time and space. These contradictions are being played out in current language debates as emigration, return migration, internal migration and immigration elicit new constructions of ‘Italianness’, the literary canon and the social weight of the different varieties of language present on Italian soil and in Italian communities abroad.

We know that scientific psychological information about research has not been placed at all psychologists’ disposal.Today in Italy, in spite of this, the scientific and research activity has been carried out by a marginal segment of psychologists who mostly work in the Academic area, but an important part of profes-sional psychologists devote themselves to research, above all in the clinical field. Researchers in Psychology publish an average of one article per year, almost always in the national language.The CRUI (Italian Universities vice-chancellors Conference has arranged an assessment parameter system for research taking into account the kind and place of editing, the score is from one to ten for editing in journals with a high Impact Factor, from one to twelve for books published both in Italy and abroad, from 0.1 to four for congress works, from 0.5 to five and from 0.2 to three for articles, included or excluded in the Journal citation report.

    Manufacturers launching next-generation or innovative medical devices in Europe face a very heterogeneous reimbursement landscape, with each country having its own pathways, timing, requirements and success factors. We selected 2 markets for a deeper look into the reimbursement landscape: France, representing a country with central decision making with defined processes, and Italy, which delegates reimbursement decisions to the regional level, resulting in a less transparent approach to reimbursement. Based on our experience in working on various new product launches and analyzing recent reimbursement decisions, we found that payers in both countries do not reward improved next-generation products with incremental reimbursement. Looking at innovations, we observe that manufacturers face a challenging and lengthy process to obtain reimbursement. In addition, requirements and key success factors differ by country: In France, comparative clinical evidence and budget impact very much drive reimbursement decisions in terms of pricing and restrictions, whereas in Italy, regional key opinion leader (KOL) support and additional local observational data are key.

    Full Text Available Abstract Background Personality disorders affect a substantial proportion of the population. It is unclear, however, whether the burden of personality disorders on modern mental health services has been increasing. To fill this gap, we analyzed trends in admissions for personality disorders in Italy from 1988 to 1998. Methods We used the yearly data from the Italian Central Institute of Statistics to analyse trends in the total number of admissions for personality disorders and in the total number of first admissions for personality disorders. Results The absolute number of admissions for personality disorders almost trebled from 1988 to 1998, as well as the proportion of all psychiatric admissions that were for personality disorders. Whilst there has been a marked increase in the absolute number of first admissions, the proportion of all first psychiatric admissions that were for personality disorders showed a steady but modest increase, from 5.7% to 7.6%. Conclusion In Italy, the burden of personality disorders on modern mental health services has been increasing. In terms of public health, these findings highlight the urgent need of developing policies to tackle the increasing demand of care of this difficult-to-treat patient population.

  17. Calibration assessment of forest flammability potential in Italy

    Full Text Available Fuel flammability is defined as the relative ease with which a fuel will ignite and burn with a flame; different forest types have different intrinsic “baseline” flammabilities, depending on the susceptibility to burn of the main tree species that build up the forest cover. In this perspective, we apply a forest-type based approach to classify and map the flammability level of the forests in Italy. Baseline forest type-based flammability values provided at European level have been assigned to a national forest types map, derived from Corine Land Cover 2006; flammability values have been then further calibrated against the Burned Area Selection Ratio, a measure of the actual incidence of wildfires among different forest types. Accordingly, a calibrated flammability index was derived by simple linear regression, so that predicted flammability more accurately reflects observed fire incidence among different forest types in Italy. Findings show that the flammability of forest types ranges from low to high: on average, the 17% of the forest cover has medium to high flammability, with wide regional variability; notably, in four Regions (Sardegna, Sicilia, Puglia, Calabria over one third of total forest area has medium to high flammability. Large scale mapping of forest flammability is crucial to define long-term priorities among forest areas as to how to distribute fire management effort: areas falling into medium to high flammability classes should be given priority for implementing fuel management treatments in order to mitigate fire hazard from the stand to the landscape scale.

  18. Morphology and evolution of sulphuric acid caves in South Italy

    Sulphuric acid speleogenesis (SAS) related to the upwelling of acid water enriched in H2S and CO2 represents an unusual way of cave development. Since meteoric infiltration waters are not necessarily involved in speleogenesis, caves can form without the typical associated karst expressions (i.e. dolines) at the surface. The main mechanism of sulphuric acid dissolution is the oxidation of H2S (Jones et al., 2015) which can be amplified by bacterial mediation (Engel et al., 2004). In these conditions, carbonate dissolution associated with gypsum replacement, is generally believed to be faster than the normal epigenic one (De Waele et al., 2016). In Italy several SAS caves have been identified, but only few systems have been studied in detail: Frasassi and Acquasanta Terme (Marche)(Galdenzi et al., 2010), Monte Cucco (Umbria) (Galdenzi & Menichetti, 1995), and Montecchio (Tuscany) (Piccini et al., 2015). Other preliminary studies have been carried out in Calabria (Galdenzi, 2007) and Sicily (De Waele et al., 2016). Several less studied SAS cave systems located in South Italy, and in particular in Apulia (Santa Cesarea Terme), Sicily (Acqua Fitusa, Acqua Mintina) and Calabria (Mt. Sellaro and Cassano allo Ionio) have been selected in the framework of a PhD thesis on SAS caves and their speleogenesis. Using both limestone tablet weight loss (Galdenzi et al., 2012) and micro erosion meter (MEM) (Furlani et al., 2010) methods the dissolution rate above and under water in the caves will be quantified. Geomorphological observations, landscape analysis using GIS tools, and the analysis of gypsum and other secondary minerals (alunite and jarosite) (stable isotopes and dating) will help to reconstruct the speleogenetic stages of cave formation. Preliminary microbiological analysis will determine the microbial diversity and ecology in the biofilms.

    Along the Serchio River (Tuscany -Italy) a series of well fields is set for an overall amount of about 1 m3/s pumped groundwater providing drinking water for about 300000 people of the coastal Tuscany (mainly to the town of Lucca, Pisa and Livorno). Water is pumped enhancing riverbank filtration into a high yield (10-2 m2/s transmissivity) sand and gravel aquifer by artificially rising river head and setting pumping well fields along the river reach. However, being it unmanaged aquifer recharge, concerns arise both for quality and quantity of the abstracted groundwater. It happens in dry climate extremes (i.e. 2002/2003 or 2011/2012) that Serchio River flow falls below minimum environmental flow (MEF). Long term contamination of river water had been causing contamination of groundwater, as in 2002/2006, when pesticide contaminated surface water was polluting the well fields causing several problems to water supply. Such problems were overcome by setting in place derogatory regulations and then through dissemination and stakeholder activities reducing pesticide presence in surface water (EU LIFE SERIAL WELLFIR project). Although widely adopted, IRF is also not well stated from a regulatory point of view, eventually leading to concerns by a legal point of view. Within the framework of the MARSOL FPVII-ENV-2013 project an experimental site at a well field will be set to demonstrate the feasibility (by a technical, social and market point of view) and the benefits of managing IRF versus the unmanaged option. The Serchio experimental site will involve merging existing and proved technologies to produce a Decision Support System (DSS) based on remote data acquisition and transmission and GIS physically-based fully distributed numerical modeling to continuously monitor and manage well fields, reducing also human operated activities. The DSS along with the installed sensors, data transmission and storage tools will constitute a prototype whose potential market exploitation

Studies have been conducted to date on the prevalence, or the associated costs, of RA in Italy. Although future changes in the incidence of RA are a matter of debate, the impact of RA on health care costs is expected to grow in coming decades in line with projected increases in life expectancy and in the proportion of elderly people in Italy. It has been estimated that the indirect (productivity loss and informal care and intangible (deterioration in health-related quality of life costs of the disease will contribute to an increase in national health service expenditure, which will correspond to 1% of the total health care costs of the nation in the near future. The introduction of biological agents for the treatment of rheumatic diseases has resulted in an increase in the direct costs of RA; however, economic analyses that exclude indirect costs will underestimate the full economic impact of RA. The effectiveness of innovative therapies in preventing disease progression and functional impairment may, over time, attenuate the cost impact of RA in terms of hospitalizations and work absenteeism. Further research is needed to develop estimates of the economic impact of different therapeutic approaches in patients with RA in Italy, in order to provide tools that can drive the choice of the most cost-effective therapeutic option while maintaining high-quality care

    Full Text Available INTRODUCTION. In view of the goal of measles elimination, it is of great importance to assess the circulation of wild-type measles virus (MV. Genetic analysis is indispensable to understand the epidemiology of measles. A large measles outbreak occurred in Italy in 2008, with over 4000 cases reported to the enhanced measles surveillance system introduced in 2007, 37% of which were laboratory confirmed. METHODS. Urine and saliva samples were collected during 2008. A phylogenetic analysis of measles sequences was performed in order to understand the epidemiological situation of wild-type (MV circulation in that period. RESULT AND DISCUSSION. Data showed predominant circulation of the genotype D4. Genotypes A, D8, D9 and H1 were also detected in a small number of samples, probably representing imported cases.

    Full Text Available INTRODUCTION: The European Regional Office of the World Health Organization (WHO/Europe developed a strategic approach to stop the indigenous transmission of measles in its 53 Member States by 2015. This study describes the measles laboratory surveillance activity performed by the National Reference Laboratory for Measles and Rubella at the Italian National Institute of Health (Istituto Superiore di Sanità during 2010. METHODS: Urine, oral fluid and capillary blood samples from 211 suspected measles cases arrived to the NRL from different regions of Italy for confirmation of the clinical diagnosis. Serological and/or molecular assays were performed; after molecular detection, positive samples were sequenced and genotyped. RESULTS AND DISCUSSION: 85% (180/211 of the specimens were confirmed as measles cases and 139 of these were analyzed phylogenetically. The phylogenetic analysis revealed a co-circulation of D4 and D8 genotypes for the reviewed period.

    Full Text Available The La Fossa cone of Vulcano Island (Aeolian Archipelago, Italy is a closed conduit volcano. Today, Vulcano Island is characterized by sulfataric activity, with a large fumarolic field that is mainly located in the summit area. A scanning differential optical absorption spectroscopy instrument designed by the Optical Sensing Group of Chalmers University of Technology in Göteborg, Sweden, was installed in the framework of the European project "Network for Observation of Volcanic and Atmospheric Change", in March 2008. This study presents the first dataset of SO2 plume fluxes recorded for a closed volcanic system. Between 2008 and 2010, the SO2 fluxes recorded showed average values of 12 t.d–1 during the normal sulfataric activity of Vulcano Island, with one exceptional event of strong degassing that occurred between September and December, 2009, when the SO2 emissions reached up to 100 t.d–1.

  7. The evolution of health-policy making in Italy.

    France, George; Taroni, Francesco

    2005-01-01

    An analysis of the dynamics of health care policy in Italy suggests that in recent years the pace of change in the health care system has accelerated. Although the basic features of universalism, comprehensiveness, and funding from general taxation have remained remarkably constant, the capacity to innovate policy tools and their settings and to take account of domestic and international experience seems to have increased. The political will and capacity to combat entrenched interests may also have increased, although implementation is still weak. The imperative to contain public expenditure has heavily conditioned health policy and will continue to do so. This has occurred mainly at the national level, but as the principal locus of health-policy making progressively shifts to the regions, so too will the constraining effect of this imperative move downward. If the decentralization process continues, problems could arise due to interregional differences in capacities to formulate and implement appropriate policies and to tackle special interest groups.

    The present research evaluated the psychosocial health and quality of life of North African (NA) immigrant women living in Italy. A survey of 205 NA-born and Italian-born women was carried out. Psychosocial, sociodemographic and migration data were collected. Anthropometric indices were computed by direct measurements of height, weight, waist and hip circumferences. Multivariate analysis showed that the main explanatory variable for all dimensions of psychosocial status was the migrant status. Other explanatory variables were educational level and number of children for psychological discomfort, and weight status for well-being, quality of life and stress. Anthropometric indices were explanatory variables for quality of life. In conclusion, this study provides further evidence of higher psychological stress and discomfort and lower well-being and quality of life in immigrant women. Public social support is necessary to control, maintain and improve the mental health outcomes of immigrant communities in the host country.

  9. Runoff generation through ephemeral streams in south-east Italy

    Ephemeral streams are morphological elements, typical of karst areas, characterized by relatively large and flat bottom transects (Camarasa & Tilford, 2002). These occasionally drain runoff generated by extreme rainfall events, characterized by high return periods. The activation of these streams was investigated by several authors for the Mediterranean regions, and in particular for south Spain and north Africa (Camarasa & Segura, 2001; De Vera, 1984). However, there are few analyses for karst areas of south-east of Italy (Cotecchia, 2006; Polemio, 2010). South-east of Italy, in particular the central part of Apulia, is characterized by a karst morphology, with a moderately elevated plateau, namely Murgia, which is drained by a network of ephemeral streams. These are normally dry, relatively short-length and straights, and their main outlets are on the coast. They normally drain water after extraordinary rainfall events, which can generate very high discharges, which can potentially flood the areas close to the streams. For this reason, the definition of an activation threshold for ephemeral streams is a paramount problem, even if this constitutes a complex problem, since the dynamics of the catchment drained by these streams in highly non-linear and biased by multiple variables (e.g. urbanization, land use, etc.). The main problem affecting the analysis and prediction of flood events in karst semi-arid regions is the almost complete absence of discharge time-series, measured at the outlets of the ephemeral streams. This prevents from the identification of accurate statistics of flood events and on the determination of rainfall events, which may potentially generate floods. Indeed, floods and in general flash floods are relatively rare events for semi-arid karst regions, however they can be really severe and disruptive, causing serious damages to people and infrastructures. This work presents an analysis of the ephemeral stream activation in karst semi-arid areas

    Avian species are considered as the main reservoir of Campylobacter spp. However, few data are available on the presence of this microorganism in pet birds. This study was therefore performed to determine the prevalence of Campylobacter spp. in pet birds bred in southern Italy. Faecal samples were collected from 88 cages housing different species of pet birds and examined by bacteriological culture and polymerase chain reaction. A total of 13.6% of the cage samples were positive for Campylobacter coli. Other Campylobacter spp. were not found. The study shows that C. coli can be isolated from the cages of apparently healthy pet birds, which should therefore be considered as potential carriers of C. coli and a possible source of infection for humans and companion animals.

    A parasitologic study on 129 red foxes (Vulpes vulpes) from Tuscany (central Italy) was carried out in 2004-2006. Five intestinal species were found at necropsy: Dipylidium caninum (prevalence 57.3%), Mesocestoides lineatus (45.4%), Uncinaria stenocephala (39.1%), Toxocara canis (9.1%), and Toxascaris leonina (5.4%). Other parasites not associated with the intestine included Crenosoma vulpis (14.7%), Capillaria aerophila (7.0%), Angiostrongylus vasorum (7.0%), and filarial parasites (17.8%). Coprologic tests were less sensitive and less specific in identifying parasites than direct examinations at necropsy. Trichinella larvae were not found in muscles submitted to artificial digestion. By immunologic assay, antigens of Echinococcus spp. were detected in fecal samples of 20 foxes, but results could not be confirmed by fecal examination or molecular tests.

    Healthcare providers often look for feedback from patient surveys. Does health-professional awareness of patient survey results improve communication between patients and providers? To test this hypothesis, we analyzed the data of two surveys on organizational-climate and patient experience in Italy. The two surveys were conducted in 26 hospitals in the Tuscany region and involved 8942 employees and 5341 patients, respectively. Statistical analysis showed that the patient experience index significantly improved by 0.35 points (scale: 0-100) when the professionals' knowledge of the patient survey results increased by 1%. These findings suggest that the control systems should focus more on the dissemination phase of patient survey results among health professionals in order to improve the quality of services.

    Full Text Available The zooplankton community structure in Lake Bracciano (Latium, Central Italy was studied in monthly surveys throughout an annual cycle (November 1998 – October 1999. The seasonal cycles and population dynamics of the dominant species are described and discussed. Copepods numerically dominated the community throughout the study period with calanoid Eudiaptomus padanus etruscosexsetosus making up the largest share of zooplankton density; moreover it accounted for the largest portion of total biovolume. Cladocerans represented a significant component of the zooplankton in the summer and autumn months. No substantial differences in regard to results of previous investigations (1971, 1972, 1984 were observed. The only differences for which there is evidence consist of the appearance of Filinia terminalis, never previously found in the lake, and the replacement of Keratella cochlearis instead of Kellicottia longispina as dominant species. However, the results of the comparison of the different investigations confirm that the trophic state of the pelagial region may be classified as oligo-mesotrophic.

    The presence of tick-borne Rickettsia spp. was examined by PCR using DNA samples extracted from 254 ticks collected from mammals originating from northern and eastern Sardinia, Italy. The spotted fever group rickettsial agent Rickettsia conorii israelensis was detected in 3 Rhipicephalus sanguineus ticks from a dog for the first time in this geographical area. In addition, Ri. massiliae, Ri. slovaca, and Ri. aeschlimannii were detected in Rh. turanicus, Rh. sanguineus, Dermacentor marginatus, and Hyalomma marginatum marginatum ticks from dogs, goats, wild boar, and horse. Moreover, Candidatus Rickettsia barbariae was detected in 2 Rh. turanicus ticks from goats. The detection of Ri. conorii israelensis, an emergent agent which causes Israeli spotted fever, increases our knowledge on tick-borne rickettsioses in Sardinia.

    The Universal Newborn Hearing Screening (UNHS) programme aims at achieving early detection of hearing impairment. Subsequent diagnosis and intervention should follow promptly. Within the framework of the Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for early Identification, Intervention and Care of Hearing Impaired Children", the limitations and strengths of current UNHS programs in Italy have been analysed by a group of professionals working in tertiary centres involved in regional UNHS programmes, using SWOT analysis and a subsequent TOWS matrix. Coverage and lost-to-follow up rates are issues related to UNHS programmes. Recommendations to improve the effectiveness of the UNHS programme have been identified. The need for homogeneous policies, high-quality information and dissemination of knowledge for operators and families of hearing-impaired children emerged from the discussion.

    The indoor radon ((222)Rn) activity concentration was measured between January and June in the schools of two geothermal areas in Tuscany, central Italy. One of these areas (the Larderello area) is characterized by a large number of geothermal power plants, covering about 9% of the world's geothermal power production. In contrast, the other area, Monte Pisano, has not any such facilities. About 250 measurements were made using track etch detectors. Only a slight difference in the concentrations between the two major sampling areas (98 Bq m(-3) for Larderello area and 43 Bq m(-3) for Monte Pisano area) was found, and this was related to different geological characteristics of the ground and not the presence of the geothermal plants. The measured radon concentrations were always well below the intervention levels in both areas, and health risks for students and personnel in the examined schools were excluded.

    Iulia Concordia is an important Roman settlement known for the production of iron objects and weapons during the Roman Empire. A huge number of well-preserved styli were found in the past century in the bed of an old channel. In order to shed light about the production processes used by Roman for stylus manufacturing, a neutron diffraction residual strain analysis was performed on the POLDI materials science diffractometer at the Paul Scherrer Institut in Switzerland. Here, we present results from our investigation conducted on 11 samples, allowing to define, in a non-invasive way, the residual strain map related to the ancient Roman working techniques. - Highlights: • We examined 11 Roman styli from the settlement of Iulia Concordia, Italy. • We performed a neutron diffraction residual strain analysis on POLDI at PSI (CH). • We identified the production processes used by Roman for stylus manufacturing. • We clarified the way and direction of working applied for different classes of styli.

    Full Text Available A new vertebrate assemblage was discovered in an Early  Miocene lacustrine deposit near the village of Laerru (northern Sardinia, Italy. The assemblage is composed by mammals, reptiles and a bird. The mammals are represented by three ruminants (cf. Sardomeryx oschiriensis, Pecora indet. small size and Pecora indet. very small size and one dormouse (Peridyromys aff. murinus while reptiles are represented by turtles (Trionychidae? and crocodiles (cf. Diplocynodon sp.. A bird bone fragment is also reported and referred to Palaeortyx cf. brevipes (Galliformes. The assemblage can be related to the “Oschiri fauna”, one of the oldest endemic insular fauna known in the Mediterranean. The age of the Laerru vertebrates is early-middle Burdigalian, between 18.8 and 18.3 Ma, corresponding to the mammal unit of the main land MN3. The predominance of ruminants confirms the good capacity of these mammals to colonize insular environments.

    This is a thermodynamic analysis of the Province of Ravenna (Italy) and its districts (Ravenna, Faenza and Lugo) and an evaluation of entropy waste production based on a balance sheet of greenhouse gases. The method used is energy analysis. The results show that the Province and Ravenna are characterized by a heavy exploitation of local non renewable resources, Faenza strikes a good balance between economic development and environment conservation and Lugo is less sustainable than the others. The greenhouse gas balance shows that the Province emits 10.5 times the quantity of greenhouse gases that it adsorbs and that the emissions reduction is required in the energy sector, which is responsible for 92% of the total.

    The prevalence of HIV/AIDS among people in midlife and late adulthood has been increasing in Western countries over the last decade. We analyzed data from a prospective, observational multi-centre study on individuals newly diagnosed with HIV between January 2004 and March 2007 in 10 public counselling and testing sites in Latium, Italy. At diagnosis, routine demographic, epidemiological, clinical and laboratory data are recorded, and patients are asked to complete a questionnaire investigating socio-demographic and psycho-behavioural aspects. To analyze the association of individual characteristics with age, we compared older adults (> or = 50 years) with their younger counterpart (18-49 years). To adjust for potential confounding effect of the epidemiological, clinical and behavioural characteristics, to identify factors associated with older age at HIV diagnosis, multivariate logistic regression analysis was performed. Overall, 1073 individuals were identified, 125 of whom (11.6%) were aged 50 years or above. The questionnaire was completed by 41% (440/1073). Compared with their younger counterparts, a higher proportion of older patients were males, born in Italy, reported heterosexual or unknown HIV risk exposure, were never tested for HIV before and were in a more advanced stage of HIV infection at diagnosis. In addition, older adults had a lower educational level and were more frequently living with their partners or children. With respect to psycho-behavioural characteristics, older patients were more likely to have paid money for sex and have never used recreational drugs. Interestingly, no differences were found regarding condom use, which was poor in both age groups. These findings may have important implications for the management of older adults with HIV, who should be targeted by appropriate public health actions, such as opportunistic screening and easier access to healthcare. Moreover, strategies including information on HIV and prevention of risk

    Italy is the country that owns most of the world cultural heritage as it's clear from the list of sites of inestimable value to humanity, prepared by UNESCO under the Convention concerning the protection of the world cultural and natural heritage ratified in 1972. The Italian territory is also particularly prone to natural hazards such as landslides, floods, earthquakes, volcanic eruptions, subsidence and coastal erosion which undermine the protection and preservation of cultural heritage. Aim of the present work is to provide an estimate of architectural, monumental and archaeological heritage exposed to landslide and flood risk at national scale. The input data are: the Italian Cultural Heritage database (Carta del Rischio del patrimonio culturale) realized by ISCR (Central Institute for the Conservation and Restoration); the Italian Landslide Inventory (Progetto IFFI) developed by ISPRA (Italian National Institute for Environmental Protection and Research) and the Regions and Self-Governing Provinces of Italy and the flood hazard zones defined by the Italian River Basin Authorities. Italian landslide inventory contains more than 486,000 landslides affecting an area of about 20,800 km2, equal to 6.9% of Italian territory. In order to estimate the number and type of cultural heritage at risk some GIS processing have been carried out, overlapping information from the above mentioned databases. The analysis provided the following results: Cultural Heritage exposed to landslide risk were estimated to 5.511 (6.6%) while the ones exposed to flood risk results 9.859 (11.7%). Two case studies concerning landslide phenomena affecting important Italian municipalities and the flood risk of historical centre of Rome, have been also analyzed. These results could be used to identify priorities and plan field surveys, detailed studies and monitoring systems, allowing job scheduling of cultural heritage maintenance. This need becomes more and more a necessity taking into account

    Background: During the last two decades, tuberculosis (TB has once again emerged as a significant public health problem in Western Countries. The aim of this study is to describe the epidemiology of TB in Italy in the last fifteen years. All routine information sources available (annual notifications, mortality and hospital discharges were used, and attempts to investigate gender and geographical differences were made. Methods: Age-standardized annual notification, mortality and hospital discharge rates were calculated. Time trends of annual notifications, mortality and hospital discharges for TB were modelled through Poisson regression, and whenever necessary, negative binomial regression.

    Results: The analysis of the temporal trend of TB using the three indicators shows an increase until the middle of 1990s and a following decrease. TB is more frequent in men than in women, with a decremental. North to South gradient. There are important geographical and gender differences of the TB decline in Italy, since the decrease of TB frequency is more pronounced in men than in women and it is less evident in the central and, to a lesser extent, the southern parts of the country.

    Discussion: Italian guidelines for TB control, which are largely consistent with the international recommendations for low-incidence countries, need to be fully implemented throughout the entire country in order to reach the ultimate goal of disease eradication. Given the high number of TB cases among foreignborn persons, a strong public health commitment on TB control for immigrants, which includes screening, prophylaxis and treatment, is urgently needed.

    2003-04-01

    We determine geometry and distribution of seismic strain in Italy, and surrounding regions, by means of seismological information, and compare results with geodetic data. We use data from the Harvard CMT Catalog, mostly supplemented by the INGV-Harvard European-Mediterranean Regional Centroid Moment Tensor (RCMT) Catalog (http://www.ingv.it/seismolgo/RCMT), including solutions for moderate-magnitude earthquakes (4.5encloses about 400 focal solutions for events occurred between 1997 and 2002, besides other significant events (e.g. the Friuli, Northern Italy, 1976 seismic sequence). We believe this to be the most complete dataset, based on instrumental data, for the last 25 years of seismic activity of the study region. Only crustal events are considered. The method used is the Kostrov summation, applied on a regular grid. We thus obtain the cumulative moment tensor, representative of the geometry of deformation. Its distribution shows NE-SW extension along the Apennines, and the compression field (rotating from NE-SW to NNE-SSW) that affects the mountain chains along the eastern coast of the Adriatic Sea and the Eastern Alps. The geometry of deformation also exhibits other intriguing trends, such as compression along the Southern Tyrrhenian, changing to strike-slip eastward, and turning to extension passing trough the Aeolian Islands and the Messina Strait. We also note the transition from compression in the outer Northern Apennines to transcurrent style in the outer Southern Apennines. Being this region a low strain rate area, a correct evaluation of strain amount requires to merge the instrumental dataset with the historical seismic moment released, as obtained from catalogs. The hypocentral distribution is taken into account to evaluate the depth of the brittle layer. Our results are compared with geodetic data recently obtained analysing more than 10 years of GPS observations collected by more than 130 stations. Significant similarity is found, especially as

    In Italy ore research and exploitation are nearly exhausted since the end of the last century, leaving on the land a huge amount of mine waste, therefore provoking evident environmental damage including landscape, vegetation and the food chain, and a potential threat to human health. The increasing environmental consciousness of general population compelled Public Administrators to set down effective legislation acts on this subject (e.g. D.L. 152/2006), and more generally on environmental contamination. In this work we present the results of a survey carried out at several mixed sulphides mine sites in Italy, exploited for at least a millennium, and closed in the '60s of the last century. Biogeochemical analyses carried out on 50 soil profiles (mostly Entisols and Inceptisols) and vegetation in the proximal and distal areas of ore exploitation show metal concentrations overcoming legislation limits on average (Cu up to 3160 mg kg-1 , Pb up to 23600 mg kg-1, Zn up to 1588 mg kg-1, Fe up to 52,30 %). Ni, Cr and Mn concentrations, instead, are generally below the reference levels. Metal concentrations in native vegetation of the examined areas are moderately to highly elevated. Significant amounts of Cu, Pb, Zn in roots of Plantago major and Silene dioica, in leaves of Taraxacum officinale, and Salix spp, have been recorded. Essential elements, in particular, present Translocation Coefficients (TC) >1, with Mn>Zn>Cu>Fe. Toxic elements (Cd, Cr, Pb), instead, present TCparks in these areas could enhance their educational and scientific value, contributing in the meantime to general population amusement and recreation. Finally, it is the occasion for soil scientists to submit to the scientific community new classification proposals of this new kind of soils.

    This study aims to estimate the mean annual social cost per patient with chronic kidney disease (CKD) by stages 4 and 5 pre-dialyses and cost components in Italy. The multicenter cross-sectional study included all adult outpatients in charge of the 14 main Nephrology Centers of Tuscany Region during 7 weeks from 2012 to 2013. Direct medical costs have been estimated using tariffs for laboratory tests, diagnostic exams, visits, hospitalization and prices for drugs. Non-medical costs included expenses of low-protein special foods, travel, and formal and informal care. Patients' and caregivers' losses of productivity have been estimated as indirect costs using the human capital approach. Costs have been expressed in Euros (2016). Totals of 279 patients in stage 4 and 205 patients in stage 5 have been enrolled. The estimated mean annual social cost of a patient with CKD were €7422 (±€6255) for stage 4 and €8971 (±€6503) for stage 5 (p < 0.05). Direct medical costs were higher in stage 5 as compared to stage 4; direct non-medical costs and indirect costs accounted, respectively, for 41 and 5 % of the total social cost of CKD stage 4 and for 33 and 9 % of CKD stage 5. In Italy, the overall annual social cost of CKD was €1,809,552,398 representing 0.11 % of the Gross Domestic Product. Direct non-medical costs and indirect costs were weighted on the social cost of CKD almost as much as the direct medical cost. Patients, their families and the productivity system sustain the burden of the disease almost as much as the healthcare system.

    2013-10-01

    Full Text Available Background: hospitalization for Ambulatory Care Sensitive Conditions (AC SC, also known as avoidable hospitalization (AH has been proposed as effect measure of the accessibility and effectiveness of primary care. In the last years in developed countries, including Italy, hospitalization rates have decreased as well as the rates of AH. The decline of AH-rates could be just an effect of the general trend of hospitalization. The objective of our study was to examine the adjusted trend of AH rates and to test possible associations with measures of primary care (reorganization.Methods: hospital discharges from 2001 to 2008 were analyzed. Main outcome measures were hospitalization rates, both as inpatient and day hospital. ACSCs were grouped in acute conditions, preventable through early diagnoses and treatment and chronic conditions, preventable through good ongoing control and management. Expected time-series rates of AH, estimated on the hypothesis of same time trends of Total Hospitalization (TH, were compared with observed ones using a Chi Square test. Adjusted hospitalization rates were analyzed in conjunction with indicators of primary care.Results: in the studied period, in Italy, the TH rates declined with an average decrease of 19.6%, while the decrease for AH was 16.4%. The rates of AH adjusted for the trend of TH significantly decreased only for chronic conditions. Decreasing trend of AH was correlated with the impact of reorganization of primary care in associative forms.Conclusions: the presented methodology can be used to evaluate the real effectiveness of policies aimed at reducing hospitalization for ACSCs.

    AIM: Our goals were to analyze the known genetic predispositions for autoimmune hepatitis (AIH) in AIH Italian population and to compare them with North American counterparts.METHODS: Human leukocyte antigens (HLA) B8, C7, DR3,DR4, DR7, DR11, DR13, DQ2 and the B8-DR3-DQ2phenotype were determined by microlymphocytotoxicity and polymerase chain reaction in 74 Italian patients (57with type 1 and 17 with type 2 AIH) and 149 North American patients with type 1 AIH, and in adequate controls.RESULTS: B8-DR3-DQ2 occurred more frequently in Italian patients with type 1 AIH than in Italian controls (30% vs 7%, P<0.0001), but less frequently than in North American counterparts (30% vs48%, P = 0.02). DR4 occurred less frequently in Italian patients with type 1 AIH (23% vs43%,P= 0.01) and in controls (16% vs34%, P= 0.0003) than in North American counterparts. No differences were found in alleles' frequency between type 1 and type 2Italian AIH patients. DR11 had a frequency lower in type 1 Italian AIH patients than controls (17% vs35%, P= 0.01).CONCLUSION: HLA DR4 is not associated with AIH in Italy. The known HLA risk factors for ATH occur similarly in Italian patients with type 1 and type 2 AIH, and they are less frequent than in North American patients. B8-DR3-DQ2 is the predominant phenotype of type 1 AIH also in Italy, and HLA DR11 may be a regionally distinctive protective factor against type 1 AIH.

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

    Full Text Available A new Digital Elevation Model (DEM of the natural landforms of Italy is presented. A methodology is discussed to build a DEM over wide areas where elevation data from non-homogeneous (in density and accuracy input sources are available. The input elevation data include contour lines and spot heights derived from the Italian Regional topographic maps, satellite-based global positioning system points, ground based and radar altimetry data. Owing to the great heterogeneity of the input data density, the DEM format that better preserves the original accuracy is a Triangular Irregular Network (TIN. A Delaunay-based TIN structure is improved by using the DEST algorithm that enhances input data by evaluating inferred break-lines. Accordingly to this approach, biased distributions in slopes and elevations are absent. To prevent discontinuities at the boundary between regions characterized by data with different resolution a cubic Hermite blending weight S-shaped function is adopted. The TIN of Italy consists of 1.39×109 triangles. The average triangle area ranges from 12 to about 13000 m2 accordingly to different morphologies and different sources. About 50% of the model has a local average triangle area <500 m2. The vertical accuracy of the obtained DEM is evaluated by more than 200000 sparse control points. The overall Root Mean Square Error (RMSE is less than 3.5 m. The obtained national-scale DEM constitutes an useful support to carry out accurate geomorphological and geological investigations over large areas. The problem of choosing the best step size in deriving a grid from a TIN is then discussed and a method to quantify the loss of vertical information is presented as a function of the grid step. Some examples of DEM application are outlined. Under request, an high resolution stereo image database of the whole Italian territory (derived from the presented DEM is available to browse via internet.

    The cadmium content of muscle, liver, kidney and blood samples from 62 horses slaughtered in Italy was investigated. Cadmium was determined by graphite furnace atomic absorption spectrometry (GFAAS) after wet digestion of the samples. The mean and median contents of all samples were (on a fresh weight basis) 75 and 41 micrograms kg-1 for muscle, 2.46 and 2.10 mg kg-1 for liver, 20.0 and 13.5 mg kg-1 for kidney. The cadmium level in blood samples was always below 6 micrograms l-1. The cadmium concentrations in muscle, liver and kidney were found to be related to the life span of the specimens and increased with age. Females exhibited higher levels than males, but this difference was significant only in the case of muscle tissue. The geographical origin was recognized as the main factor influencing the cadmium content of the equine specimens analysed. The differences between horses coming from the three main breeding countries considered in this study (Poland, Lithuania, Hungary) were marked and statistically significant. The average intake of cadmium from equine meat was estimated for the general population and for population groups resident in areas with high consumption of this food item. While the cadmium intake from equine meat for the average consumer accounts for about 1% of the total cadmium intake estimated for Italy, in the latter case the enhanced consumption of equine muscle is often accompanied with the consumption of substantial quantities of equine liver and this may lead to high cadmium intakes.

  12. Spending on pharmaceuticals in Italy: macro constraints with local autonomy.

    2003-01-01

    Italy has a national health service (SSN) that is moving toward decentralization and empowerment of local health enterprises (LHEs)-the arms of the regions for delivering health services. Drug policy and spending decisions are both influenced by central government and local authorities. At the "macro" level, the government holds the power to decide the amount of drug expenditure, currently at 13% of total SSN expenditure; the pricing policy, price negotiation, reference price, and price cuts; criteria for reimbursement, inclusion in the positive list, and restrictive notes; and the copayments and exemptions. So far, the government concern has been predominantly on cost containment, and its approach in selecting drugs for reimbursement has been cost minimization. Italy has no centralized office for health technology assessment and this hinders the search for an efficient use of drugs. At the "micro" level, however, the LHEs are showing a great vitality in fostering a better use of drugs by general practitioners. One of the tools employed is local voluntary agreements between LHEs and general practitioners (GPs) that may be supported by economic incentives, in cash or in kind. In 2000 there were 61 agreements in place, 31% of total LHEs, which concerned the respect of drug expenditure ceilings and the local development and implementation of clinical guidelines (47% of LHEs). A traditional and widespread tool for controlling drug expenditure is providing GPs with regular reports on their drug prescriptions (59% of LHEs). Monitoring, moral suasion, and clinical guidelines are the main incentives for efficiency at local level, but focus on health outcomes is limited. The cost-containment mentality still prevails and the use of drug budget for purchasing better health is at its very early stage.

    2015-04-01

    On October the 3rd 2014, a one-day Workshop on Managed Aquifer Recharge (MAR) experiences in Italy took place at the GEOFLUID fair in Piacenza. It was organized within the framework of the EIP AG 128 - MAR Solutions - Managed Aquifer Recharge Strategies and Actions and the EU FPVII MARSOL. The event aimed at showcasing present experiences on MAR in Italy while at the same time starting a network among all the Institutions involved. In this contribution, we discuss the state of MAR application in Italy and summarize the outcomes of that event. In Italy aquifer recharge is traditionally applied unintentionally, by increasing riverbank filtration or because of excess irrigation. A certain interest for artificial recharge of aquifers arose at the end of the '70s and the beginning of the '80s and tests have been carried out in Tuscany, Veneto and Friuli Venezia Giulia. During the last years some projects on aquifer recharge were co-financed by the European Commission mainly through the LIFE program. Nearly all of them use the terminology of artificial recharge instead of MAR. They are: - TRUST (Tool for regional - scale assessment of groundwater storage improvement in adaptation to climate change, LIFE07 ENV/IT/000475; Marsala 2014); - AQUOR (Implementation of a water saving and artificial recharging participated strategy for the quantitative groundwater layer rebalance of the upper Vicenza's plain - LIFE 2010 ENV/IT/380; Mezzalira et al. 2014); - WARBO (Water re-born - artificial recharge: innovative technologies for the sustainable management of water resources, LIFE10 ENV/IT/000394; 2014). While the TRUST project dealt in general with aquifer recharge, AQUOR and WARBO focused essentially on small scale demonstration plants. Within the EU FPVII-ENV-2013 MARSOL project (Demonstrating Managed Aquifer Recharge as a Solution to Water Scarcity and Drought; 2014), a dedicated monitoring and decision support system is under development to manage recharge at a large scale

    Full Text Available European Union has been dealing with the migration phenomenon for a very long time. However, after the fall of the Berlin Wall, in 1989, this topic has proved to be more present than ever. Backed by the economic crisis and by the failure of the national elites to find optimal solutions for facing the emergence of new local communities, the issue expanded. Therefore, we presently have to deal with the need of the local elites to justify the imposition of some increasingly restrictive political practices. In Italy for instance, starting with 2007, the „stranger” slowly came to be substituted by „immigrant”; a stereotype eventually giving rise to a powerful psychosis concerning Romanian immigrants, by and large. The introducing of false concerns on the political agenda was a direct consequence of the political action which marked out the „Romanian problem” as the tagline for the 2008 Parliamentary elections.

    Full Text Available The therophytic basiphilous vegetation of Central Italy has been generally framed in a single association Trifolio scabri- Hypochoeridetum achyrophori Biondi et al. 1997. We show that a considerable floristic variation exists inside Trifolio-Hypochoeridetum in Central Italy, and that it should be treated as a complex of no less than five different associations: Medicagini rigidulae-Trifolietum scabri Fanelli et al. hoc loco, Trifolio scabri-Hypochoeridetum achyrophori Biondi, Izco. Ballelli & Formica 1997 s.s, Hippocrepido siliquosae- Brachypodietum distachyi Fanelli et al. ad interim, Trigonello gladiatae-Brachypodietum distachyi Fanelli et al. hoc loc, Crucianello latifoliae-Hypochoeridetum achyrophori Filesi, Blasi, Di Marzio 1996. These associations are floristically and ecologically distinct, and show different geographical ranges in Central Italy. The great diversity of Trachynion distachyae in Central Italy is related to the widespread occurrence of limestone and calcareous alluvial rocks and to a climate with abundant winter and autumn rains very favourable to the development of winter annuals.

    Full Text Available The aim of this paper is to examine the earnings dynamic in Italy, in order to explain earnings differences between southern Italy and centralnorthern Italy. In our analysis we use different techniques: ordinary least squares (OLS, quantile regression models and the algorithm developed by Machado and Mata (2005. In particular, the Machado and Mata (2005 algorithm allows us to examine the relative importance of both differences in workers’ characteristics and in their returns in explaining southern, central and northern Italy earnings differences at a point in time, as well as across time within each macro-area. We focus on the role of differences in educational endowment and returns to education, one of the most important components of human capital in the stylised literature. The level of education determines the substantial disparities in terms of wage returns. However, this holds only for levels of education related to compulsory education.

    Full Text Available Abstract Background In the last years Italy is confronting with massive migratory movements from developing countries where hemoglobinopathies are widespread. This is causing a large diffusion and a changing spectrum in the epidemiology of hemoglobin disorders in Italy. Methods Investigations recently published in Italy on hemoglobinopathies among immigrants were revised in order to appreciate the impact of immigration from developing countries on epidemiology of these pathologies and to outline adequate guidelines of prevention. Results Although in Italy there is a limited number of investigations regarding the relation between immigration and hemoglobin disorders, published data show that in our Nation there is a changing and increasing spectrum of hemoglobinopathies linked to immigration. Conclusions Prospective and retrospective actions of public healthy preventive policy are requested, based upon information (health educational programs for immigrants and caregivers, screenings among immigrants (school screening, pre-marital, preconception and early pregnancy screening, newborn screening, counseling for foreign at-risk couples and healthy carriers.
