    1994-01-01

    Mt. Vesuvius, one of the best known volcanoes in the world primarily for the eruption that buried the Roman city of Pompeii, is shown in the center of this radar image. The central cone of Vesuvius is the dark purple feature in the center of the volcano. This cone is surrounded on the northern and eastern sides by the old crater rim, called Mt. Somma. Recent lava flows are the pale yellow areas on the southern and western sides of the cone. Vesuvius is part of a large volcanic zone which includes the Phalagrean Fields, the cluster of craters seen along the left side of the image. The Bay of Naples, on the left side of the image, is separated from the Gulf of Salerno, in the lower left, by the Sorrento Peninsula. Dense urban settlement can be seen around the volcano. The city of Naples is above and to the left of Vesuvius; the seaport of the city can be seen in the top of the bay. Pompeii is located just below the volcano on this image. The rapid eruption in 79 A.D. buried the victims and buildings of Pompeii under several meters of debris and killed more than 2,000 people. Due to the violent eruptive style and proximity to populated areas, Vesuvius has been named by the international scientific community as one of fifteen Decade Volcanoes which are being intensively studied during the 1990s. The image is centered at 40.83 degrees North latitude, 14.53 degrees East longitude. It shows an area 100 kilometers by 55 kilometers (62 miles by 34 miles.) This image was acquired on April 15, 1994 by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the Space Shuttle Endeavour. SIR-C/X-SAR, a joint mission of the German, Italian and the United States space agencies, is part of NASA's Mission to Planet Earth.

    In recent years it was discovered that the Middle to Late Holocene infi ll of the Agro Pontino graben (Central Italy) held a tephra layer originating from the Avellino eruption of the Vesuvius volcano. The eruption is dated to 1995 ± 10 calBC and took therefore place during the Early Bronze Age.

    Cultural and political contexts are important in determining the ways in which communities respond to volcanic eruptions. Understanding the manner in which communities and the State apparatus have coped with historic eruptions can provide insights into how responses have influenced vulnerability and resilience. The 1906 eruption of Vesuvius is well suited for such a study as it was one of the first major eruptions in which there was a significant element of State control, and this worked alongside more traditional pre-industrial responses. This eruption was extensively reported in the regional, national and international press and in archives which include still photography. One feature is the rich archive of material published in English language newspapers of record which are analysed fully in the paper for the first time. Many of these data sources are now accessible on-line. The eruption started on April 4th with mild explosive activity and the eruption of lava from 5th to 7th April. On the night of the 7th/8th, activity intensified when a vigorous lava fountain inclined obliquely to the north east, deposited a thick layer of tephra on the towns of Ottaviano and San Giuseppe. This led to roof collapse and a large number of fatalities. There was increased lava emission and a flow progressed south through the outskirts of Boscotrecase cutting the Circumvesuviana railway line and almost reaching Torre Annunziata. Following April 8th the eruption declined and ended on April 21st. In the initial responses to the eruption pre-industrial features were prominent, with the local communities showing social cohesion, self-reliance and little panic. A more negative aspect was the traditional religious response that involved the use of liturgies of divine appeasement and which included the use of saintly relics and images. There is interesting evidence, however, that this coping strategy was driven by the populace rather than by the clergy. The inhabitants of San Giuseppe

  5. The stress field beneath Mt. Vesuvius (Southern Italy)

    The Somma-Vesuvius is the smallest and one of the youngest volcanoes of the Neapolitan district. Its origin is linked to a Late Pleistocene-Holocene extension occurred along the entire Tyrrhenian margin of the Apennine chain. Nowadays, Mt. Vesuvius is a quiescent strato-volcano. Using different approaches and a comparison between observations and numerical models we have determined the spatial variations in the stress field beneath the volcano edifice. In order to achieve this target we have analyzed a focal mechanism dataset derived from 197 events recorded from Jan. 1999 to Jan. 2012. The main results highlight the presence of two seismogenic volumes characterized by markedly different stress patterns. The two volumes are separated by a layer where the seismic strain release shows a significant decrease. Previous studies postulated the existence, at about the same depth, of a ductile layer allowing the spreading of the Mt. Vesuvius edifice. We interpreted the difference in the stress pattern within the two volumes as the effect of a mechanical decoupling caused by the aforementioned ductile layer. The stress pattern in the top volume is dominated by a reverse faulting style, which agrees with the hypothesis of a seismicity driven by the spreading process. On the other hand, the stress field determined for the deep volume is consistent with a background regional field locally perturbed by the effects of the topography and of heterogeneities in the volcanic structure. Since the seismicity of the deep volume shows an intermittent behaviour and has shown to be linked to geochemical variations in the fumaroles of the volcano, we hypothesize that it results from the effect of fluid injection episodes, possibly of magmatic origin, perturbing the pore pressure within the hydrothermal system. The retrieved changes in the stress pattern could indicate variations in volcano dynamics potentially linked to the intrusion of magma at shallow depth.

    Existing 3-D density models of the Somma-Vesuvius volcanic complex (SVVC), Italy, largely disagree. Despite the scientific and socioeconomic importance of Vesuvius, there is no reliable 3-D density model of the SVVC. A considerable uncertainty prevails concerning the presence (or absence) of a dense body underlying the Vesuvius crater (1944 eruption) that is implied from extensive seismic investigations. We have acquired relative gravity measurements at 297 stations, including measurements in difficult-to-access areas (e.g., the first-ever measurements in the crater). In agreement with seismic investigations, the simultaneous inversion of these and historic data resolves a high-density body that extends from the surface of the Vesuvius crater down to depths that exceed 2 km. A 1.5-km radius horseshoe-shaped dense feature (open in the southwestern sector) enforces the existing model of groundwater circulation within the SVVC. Based on its volcano-tectonic evolution, we interpret volcanic structures that have never been imaged before.

  7. Remote sensing of volcanic terrains by terrestrial laser scanner: preliminary reflectance and RGB implications for studying Vesuvius crater (Italy

    Full Text Available This work focuses on the use of terrestrial laser scanner (TLS in the characterization of volcanic environments. A TLS survey of the Vesuvius crater (Somma-Vesuvius volcano, Italy allows the construction of an accurate, georeferenced digital model of different sectors of the crater. In each sector, the intensity is computed for each point as the ratio between the emitted amplitude and the received one, normalized to the maximum signal, providing the radiometric information. Moreover, the RGB colours of the observed surfaces can be captured by means of a calibrated camera mounted on the TLS instrument. In this way, multi-band information is given, since a long range TLS operates in the near infrared band. The reflectance and RGB data are compared in order to verify if they are independent enough to be complementary for model analysis and inspection. Results show that the integration of RGB and intensity data can fully characterize this volcanic environment. The collected data are able to discriminate different volcanic deposits and to detect their stratigraphic features. In addition, our results shed light on the spatial extension of landslides and on the dimensions of rock fall/flow deposits affecting the inner walls of the crater. The remotely acquired TLS information from the Vesuvius crater is compared with that from a sedimentary terrain (coal-shale quarry to detect possible similarities/differences between these two geological environments.

  8. A possible link between faulting, cryptodomes and lateral collapses at Vesuvius Volcano (Italy)

    2012-06-01

    Vesuvius is an active volcano that has been affected by late Quaternary lateral collapses and tectonic faults. Cryptodomes and two debris avalanche, 18 ka-old DA1 and 3.5 ka-old DA2, were previously documented off Vesuvius and for the younger avalanche a link between onshore and offshore stratigraphy was reconstructed. The interpretation of seismic reflection profiles off Vesuvius, borehole stratigraphies, onshore and geomorphological data allowed to recognise the relationships among debris avalanches, criptodomes and faulting. Stratigraphic data reveal a remarkable difference between the architecture of the northern and southern volcano sectors that is compatible with the occurrence of the DA1 debris avalanche in the southern volcano sector. A contour map and a three-dimensional model of a surface merging the morphology of the top of the Somma lavas, in the northern volcano sector, with that of the top of the DA1 debris avalanche, in the southern volcano sector, were reconstructed. We present a new lateral collapse model of Vesuvius Volcano and document the relevance of inherited tectonic faults in guiding collapse geometry. It is possible that the SW-directed collapse (DA1) was driven towards the hangingwall blocks of NW-SE normal faults, while the propagation of the W-directed collapse (DA2) can be ascribed to the activity of the E-W strike-slip fault. Because of their distal location a minor role of cryptodome intrusion on collapses of Vesuvius can be postulated. The detailed analysis of substrate and edifice structure presented here establishes clear connexion between substrate tectonics and lateral collapse. This approach broadens the horizons of volcanic hazard assessment of Vesuvius.

    This study reports the first crystal chemical database resulting from a detailed structural investigation of trioctahedral micas found in xenolithic ejecta produced during the AD 1631, 1872 and 1944 eruptions, three explosive episodes of recent volcanic period of Vesuvius volcano (Southern Italy). Three xenolith types were selected: metamorphic/metasomatic skarns, pyrometamorphic/hydrothermally altered nodules and mafic cumulates. They are related to different magma chemistry and effusive styles: from sub-plinian and most evolved (AD 1631 eruption) to violent strombolian with medium evolution degree (AD 1872 eruption) to vulcanian-effusive, least evolved (AD 1944 eruption) event, respectively. Both xenoliths and micas were investigated employing multiple techniques: the xenoliths were characterized by X-ray fluorescence, inductively-coupled plasma-mass spectrometry, optical microscopy, X-ray powder diffraction, and quantitative energy-dispersive microanalysis; the micas were studied by electron probe microanalysis and single crystal X-ray diffraction. The mica-bearing xenoliths show variable texture and mineralogical assemblage, clearly related to their different origin. Based on the major oxide chemistry, only one xenolithic sample falls in the skarn compositional field from the Somma-Vesuvius literature, some fall close to the skarns and cumulate fields, others plot close to the syenite/foidolite/essexite field. A subgroup of the selected ejecta does not fall or approach any of the compositional fields. Trace and rare earth element patterns show some petrological affinity between studied xenoliths and erupted magmas with typical Eu, Ta and Nb negative anomalies. Strongly depleted patterns were detected for the 1631 metamorphic/metasomatic skarns xenoliths. Three distinct mica groups were distinguished: 1) Mg-, Al-rich, low Ti-bearing, low to moderate F-bearing varieties (1631 xenolith), 2) Al-moderate, F- and Mg-rich, Ti-, Fe-poor varieties (1872 xenolith), and 3

    Sixteen nephelines from different geological occurrences were sampled at the type-locality, the Somma-Vesuvius volcanic complex (southern Italy), and investigated for their chemistry and crystal structure obtained by both single-crystal and powder X-ray diffraction. Nepheline-bearing samples are metamorphic or from magmatic ejecta and pumice deposits. The lower K contents characterize the pumice- and some metamorphic-derived nephelines, whereas the higher ones are found in some samples from magmatic nodules. The amount of the anorthite molecule, quite low on average, can be more variable in the metamorphic nephelines. The crystal-structure investigations on Somma-Vesuvius samples compare well with previous studies of natural nephelines. All 16 nepheline samples adopt space group P63. The observed lattice parameters vary between 9.9768-9.9946 Å (for a) and 8.3614-8.3777 Å (for c), respectively. Furthermore, chemical analysis revealed that all specimens exhibit an excess of Si relative the ideal Si:Al ratio of 1:1. The analysis of the T-O distances in our samples clearly indicates a distinct ordering process of aluminium and silicon on the tetrahedral sites which is an agreement with Loewenstein's rule. A linear correlation between the distance of symmetry equivalent split atoms O(1)-O(1)' and the T(1)-O(1)- T(2) tilt angle was observed. The average ( B = Na) distances of all crystals are very similar which is consistent with the outcome of the site population refinement indicating full occupancy with sodium. Oriented precession-type sections of reciprocal space indicated the presence of at least the most intense family of satellite peaks, demonstrating that this group of satellite reflections can occur not only in nephelines from pegmatites and ijolites but also in rocks from completely different petrological settings.

  11. Suitability of energy cone for probabilistic volcanic hazard assessment: validation tests at Somma-Vesuvius and Campi Flegrei (Italy)

    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.

    Studies of some 70 bore holes around ancient Pompeii, on the southwestern slope of the Somma-Vesuvius volcano, allow the reconstruction of Holocene environments earlier than the A.D. 79 eruption. This eruption produced about 10 km3 of pyroclastic material that buried the Roman cities of Pompeii, Herculaneum, and Stabiae and promoted a shoreline progradation of 1 km. The Sarno coastal plain, in a post-Miocene sedimentary basin, has been affected by Somma-Vesuvius volcanic activity since the late Pleistocene. At the Holocene transgressive maximum, the sea reached an area east of ancient Pompeii and formed a beach ridge (Messigno, 5600 and 4500 14C yr B.P.) more than 2 km inland from the present shore. Progradation of the plain due to high volcanic supply during the following highstand resulted in a new beach ridge (Bottaro-Pioppaino, 3600 14C yr B.P.) 0.5 km seaward of the Messigno ridge. Ancient Pompeii was built as the shoreline continued to prograde toward its present position. Deposits of the A.D. 79 eruption blanketed the natural levees of the Sarno River, marshes near the city and on the Sarno's floodplain, the morphological highs of Messigno and Bottaro-Pioppaino beach ridges, and the seashore. That shore was probably 1 km landward of the present one.

    Full Text Available In order to put new constrains on magnetic effects associated with mechanical stresses, high frequency monitoring of the geomagnetic field was carried out during a seismic tomography experiment (TOMOVES'96 project at Mt. Vesuvius. Eight proton precession and one Cesium magnetometers were installed along a profile on the SW flank of the volcano to observe possible magnetic changes induced by explosions. Measurements were performed at different sampling frequencies (10 Hz, 0.5 Hz and 0.1 Hz. A remarkable change in the intensity of the magnetic field was observed in only one case. The magnetic transient lasted 12-13 min, reaching the maximum amplitude of slightly less than 15 nT.

  14. Isotopic composition of Pb and Th in interplinian volcanics from Somma-Vesuvius volcano, Italy

    We present a detailed isotopic study of volcanic rocks emitted from Somma-Vesuvius volcano during three periods of interplinian activity: "Protohistoric" (3550 y B.P. to 79 A.D.), "Ancient Historic" (79 to 472 A.D.) and "Medieval" (472 to 1631 A.D.). Pb isotopic compositions of two acid leached fractions and whole rock residues of 37 whole rock samples (determined by Somma et al., 2001) show that each of the three interplinian periods is distinguished by small, systematic, and unique uranogenic and thorogenic Pb isotopic trends. This key and novel feature is compatible with the notion that the Pb isotopic data reflect small-scale source heterogeneity operating over relatively short periods of time. From this representative group of samples, a selected set of nine whole rocks were analysed for Th isotopes. 232Th/238U ratios in the source can be obtained independently from Pb and from Th isotopes. Those obtained from Pb isotopes represent source ratios, time-integrated over the whole age of the Earth; they range from 3.9 to 4.1. 232Th/238U obtained from Th isotopes are those of the present source. They are lower, and cluster around 3.5; this difference probably indicates recent U enrichment of the present source. The behaviour of Pb, as inferred by its isotopic ratios, is quite distinct from that of Sr and Nd isotopes: Pb isotope variations are not correlated to Sr or Nd isotope variations. The isotopic contrast is compatible with the idea that the isotopes were decoupled during magmatic production, evolution, and ascent through the crust. Thus, the Pb isotopes do not reflect the effects of the same processes as in the case of the Sr and Nd isotopes, or, as we also favor, they do not necessarily reflect the same source contributions into the magmas. Moreover, the Pb isotopic evolution of the interplinian rocks chiefly reflects mixing, driven by processes that are superimposed on, and independent of, other source contributions that determine the isotopic compositions

    Time spans of soil formation and climate changes occurred during the late Pleistocene to the middle Holocene are investigated in a pedostratigraphic succession located in the piedmont of the Somma-Vesuvius volcano (Campania region, southern Italy) using a multidisciplinary approach. We focused on five well-known and well-dated primary tephra and four interlayered volcanic soils developed on and/or buried by them. The pyroclastic layers give detailed chronological constraints to the stratigraphy. From bottom to top the following tephra were identified in the field: Pomici di Base (22 ka BP), Pomici Verdoline (19 ka BP), Agnano Pomici Principali (12.26 ka BP), Mercato (8.9 ka BP) and Avellino (3.9 ka BP), all of them representing volcanic products of explosive eruptions of the Somma-Vesuvius, except the third one, sourced from the westerly Phlegrean Fields. The four pedons were characterized in terms of morphological, physical, chemical, mineralogical and micromorphological features. Special attention was given to reconstruct the main soil-forming processes, paleoenvironmental and paleoclimatic conditions, degree of soil development and associated time ranges. Moreover, further tephra were identified in the field within some of above pedons. One of them was easily recognized and referred to the Agnano Monte Spina eruption (4.2-4.3 ka BP, Phlegrean Fields provenance), whereas the others were not previously known in the Somma-Vesuvius stratigraphy. On the basis of SEM-EDS analyses (chemical composition and morphoscopic observations), coupled with their stratigraphic position and literature compositional databases, they were related to the Soccavo 4-5 and the Tufi Biancastri eruptions from the Phlegrean Fields. This interpretation permitted to fix further age constrains for more detailed assessment of rates of soil formation and climatic interpretation. Major late Quaternary climatic phases are suggested by changes in the extent of development of andic properties, iron

    Nodules (coarse-grain "plutonic" rocks) were collected from the ca. 20 ka Pomici di Base (PB)-Sarno eruption of Mt. Somma-Vesuvius, Italy. The nodules are classified as monzonite-monzogabbro based on their modal composition. The nodules have porphyrogranular texture, and consist of An-rich plagioclase, K-feldspar, clinopyroxene (ferroan-diopside), mica (phlogopite-biotite) ± olivine and amphibole. Aggregates of irregular intergrowths of mostly alkali feldspar and plagioclase, along with mica, Fe-Ti-oxides and clinopyroxene, in the nodules are interpreted as crystallized melt pockets. Crystallized silicate melt inclusions (MI) are common in the nodules, especially in clinopyroxenes. Two types of MI have been identified. Type I consists of mica, Fe-Ti-oxides and/or dark green spinel, clinopyroxene, feldspar and a vapor bubble. Volatiles (CO2, H2O) could not be detected in the vapor bubbles by Raman spectroscopy. Type II inclusions are generally lighter in color and contain subhedral feldspar and/or glass and several opaque phases, most of which are confirmed to be oxide minerals by SEM analysis. Some of the opaque-appearing phases that are below the surface may be tiny vapor bubbles. The two types of MI have different chemical compositions. Type I MI are classified as phono-tephrite — tephri-phonolite — basaltic trachy-andesite, while Type II MI have basaltic composition. The petrography and MI geochemistry led us to conclude that the nodules represent samples of the crystal mush zone in the active plumbing system of Mt. Somma-Vesuvius that were entrained into the upwelling magma during the PB-Sarno eruption.

    Mafic phenocrysts from selected products of the last 4 ka volcanic activity at Mt. Vesuvius were investigated for their chemical and O-isotope composition, as a proxy for primary magmas feeding the system. 18O/ 16O ratios of studied Mg-rich olivines suggest that near-primary shoshonitic to tephritic melts experienced a flux of sedimentary carbonate-derived CO 2, representing the early process of magma contamination in the roots of the volcanic structure. Bulk carbonate assimilation (physical digestion) mainly occurred in the shallow crust, strongly influencing magma chamber evolution. On a petrological and geochemical basis the effects of bulk sedimentary carbonate digestion on the chemical composition of the near-primary melts are resolved from those of carbonate-released CO 2 fluxed into magma. An important outcome of this process lies in the effect of external CO 2 in changing the overall volatile solubility of the magma, enhancing the ability of Vesuvius mafic magmas to rapidly rise and explosively erupt at the surface.

    The spatial distributions of primary deposits and related reworked ones from Plinian fallout and from pyroclastic density currents (PDCs) of the AD 79 eruption of Somma-Vesuvius were independently modeled for the Sarno River plain (Campania, Italy). The simulation takes into consideration both primary deposition of the volcanic products and their secondary redistribution by geomorphic processes of erosion, transport, and redeposition. We hypothesize that the pre-eruption topography controlled both the intial volcanic deposition of PDCs and the subsequent processes redistributing material of the pumice fallout and PDC deposits, and thus significantly controlled the thickness of the final volcaniclastic deposits. The methodology applied is based on a reconstructed pre-AD 79 digital elevation model of the Sarno River plain, an extensive tephrostratigraphic dataset from about 1,200 core drillings and a predictive modeling technique. The two models produce contrasting spatial distribution patterns for both the AD 79 deposits from fallout plus their derivates, versus from PDCs and their derivatives. The contrast allows determination of the most important factors controlling the thickness of the AD 79 volcaniclastic deposits. This provides new insights into the process dynamics during and immediately after the AD 79 Plinian eruption including primary deposition, erosion, and redistribution.

    Major, trace element and isotopic (Sr, Nd, Pb) data are reported for representative samples of interplinian (Protohistoric, Ancient Historic and Medieval Formations) activity of Mt. Somma-Vesuvius volcano during the last 3500 years. Tephra and lavas exhibit significant major, trace element and isotopic variations. Integration of these data with those obtained by previous studies on the older Somma suites and on the latest activity, allows to better trace a complete petrological and geochemical evolution of the Mt. Somma-Vesuvius magmatism. Three main groups of rocks are recognized. A first group is older than 12.000 yrs, and includes effusive-explosive activity of Mt. Somma. The second group (8000-2700 yrs B.P.) includes the products emitted by the Ottaviano (8000 yrs. B.P.) and Avellino (3550 yrs B.P.) plinian eruptions and the interplinian activity associated with the Protohistoric Formation. Ancient Historic Formation (79-472 A.D.), Medieval Formation (472-1139 A.D.) and Recent interplinian activity (1631-1944 A.D.) belong to the third group of activity (79-1944 A.D.). The three groups of rocks display distinct positive trends of alkalis vs. silica, which become increasingly steeper with age. In the first group there is an increase in silica and alkalis with time, whereas an opposite tendency is observed in the two younger groups. Systematic variations are also evident among the incompatible (Pb, Zr, Hf, Ta, Th, U, Nb, Rb, Cs, Ba) and compatible elements (Sr, Co, Cr). REE document variable degrees of fractionation, with recent activity displaying higher La/Yb ratios than Medieval and Ancient Historic products with the same degree of evolution.

    Alkaline volcanism produced by Monte Somma-Vesuvius volcano includes explosive plinian and subplinian activity in addition to effusive lava flows. Pumice, scoria, and lava (150 samples) exhibit major- and trace-element gradients as a function of SiO2 (58.9-47.2 wt%) and MgO (0-7.8 wt%); Mg value are ???50. Internally gradational chemical groups or cycles are distinguished by age: (1) 25 000 to 14 000 yr B.P.; (2) 8000 yr B.P. to A.D. 79; and (3) A.D. 79 to 1944. A small number of lavas, dikes and scora were also analysed from the Somma formation (~ 35 000 to 25 000 yr B.P.). Within each group, contents of Na2O + K2O increas with decreasing MgO along distinct rocks. Nb/Y values are variable from 0.66 to 3.14 (at SiO2 ??? 50 wt%) generally in the range of alkaline and ultra-alkaline rocks. Variations in contents of some majro elements (e.g., P and Ti), and trace elements (e.g., Th, Nb, Ta, Zr, Hf, Pb, La, and Sc), as well as contrasting trends in ratios of various elements (e.g., Ta/Yb, Hf/U, Th/Ta, Th/Hf, Th/Yb, etc.) are also generally consistent with the group subdivisions. For example, Th/Hf increases from ??? 5 to ??? 10 with decreasing age for the Vesuvius system as a whole, yielding similar compositions in the least evolved rocks (low-silica, high-MgO, imcompatible element-poor) erupted at the end of each cycle. Internal variations within individual eruptions also systematically changed generally towards a common mafic composition at the end of each cycle, thus reflecting the dominanit volume in the magma chamber. At the start of a new eruptive cycle, the rocks are relatively enriched in incompatible elements; younger groups also contain higher abundances than other groups. N-MORB-normalized multielement diagrams exhibit selective enrichments of Sr, K, Rb, Th, and the light rare-earth elements; deep Nb and Ta negative anomalies commonly seen in rocks generated at orogenic margins are absent in the light rare-earth elements; deep Nb and Ta netgative anomalies

    Probabilistic hazard assessments of Pyroclastic Density Currents (PDCs) are of great interest for decision-making purposes. However, there is a limited number of published works available on this topic. Recent advances in computation and statistical methods are offering new opportunities beyond the classical Monte Carlo (MC) sampling which is known as a simple and robust method but it usually turns out to be slow and computationally intractable. In this work, Titan2D numerical simulator has been coupled to Polynomial Chaos Quadrature (PCQ) to propagate the simulator parametric uncertainty and compute VEI-based probabilistic hazard maps of dense PDCs formed as a result of column collapse at Vesuvius volcano, Italy. Due to the lack of knowledge about the exact conditions under which these PDCs will form, Probability Distribution Functions (PDFs) are assigned to the simulator input parameters (Bed Friction Angle and Volume) according to three VEI sizes. Uniform distributions were used for both parameters since there is insufficient information to assume that any value in the range is more likely that any other value. Reasonable (and compatible) ranges for both variables were constrained according to past eruptions at Vesuvius volcanic system. On the basis of reasoning above a number of quadrature points were taken within those ranges, which resulted in one execution of the TITAN2D code at each quadrature point. With a computational cost several orders of magnitude smaller than MC, exceedance probabilities for a given threshold of flow depth (and conditional to the occurrence of VEI3, VEI4 and VEI5 eruptions) were calculated using PCQ. Moreover, PCQ can be run at different threshold values of the same output variable (flow depth, speed, kinetic energy, …) and, therefore, it can serve to compute Exceedance Probability curves (aka hazard curves) at singular points inside the hazard domain, representing the most important and useful scientific input to quantitative risk

    A methodology was developed to reconstruct the Roman topography and environmental features of the Sarno River plain, Italy, before the AD 79 eruption of the Somma-Vesuvius volcanic complex. We collected, localized and digitized more than 1800 core drilling data to gain a representative network of stratigraphical information covering the entire plain. Besides other stratigraphical data including the characteristics of the pre-AD 79 stratum, the depth to the pre-AD 79 surface was identified from the available drilling documentations. Instead of a simple interpolation method, we used a machine based learning approach based on classification and regression trees to reconstruct the pre-AD 79 topography. We hypothesize that the present-day topography reflects the ancient topography and related surface processes, because volcanic deposits from the AD 79 eruption coated the ancient landscape. Thus, ancient physiographic elements of the Sarno River plain are still recognizable in the present-day topography. Therefore, a high-resolution, present-day digital elevation model (DEM) was generated. A detailed terrain analysis yielded 15 different primary and secondary topographic indices. Subsequently, a classification and regression model was applied to predict the depth of the pre-AD 79 surface combining present-day topographic indices with other physiographic data. This model was calibrated with the measured depth of the pre-AD 79 surface. The resulting pre-AD 79 DEM was compared with the classified characteristic of the pre-AD 79 stratum, identified from the drilling documentations. This allowed the reconstruction of pre-AD 79 environmental features of the Sarno River plain such as the ancient coastline, the paleo-course of the Sarno River and its floodplain. To the knowledge of the authors, it is the first time that the pre-AD 79 topography of the Sarno River plain was systematically reconstructed using a detailed database and sophisticated data mining technologies.

    and, finally, assess the probability of occurrence of lahars of different volumes. The information utilized to parametrize the BBNs includes: (1) datasets of lahar observations; (2) numerical modelling of tephra fallout and PDCs; and (3) literature data. The BBN framework provides an opportunity to quantitatively combine these different types of evidence and use them to derive a rational approach to lahar forecasting. Lastly, we couple the BBN assessments with a shallow-water physical model for lahar propagation in order to attach probabilities to the simulated hazard footprints. We develop our methodology at Somma-Vesuvius (Italy), an explosive volcano prone to rain-triggered lahars or debris flows whether right after an eruption or during inter-eruptive periods. Accounting for the variability in tephra-fallout and dense-PDC propagation and the main geomorphological features of the catchments around Somma-Vesuvius, the areas most likely of forming medium-large lahars are the flanks of the volcano and the Sarno mountains towards the east.

Within the geoarchaeological research project "Reconstruction of the Ancient Cultural Landscape of the Sarno River Plain" undertaken by the German Archaeological Institute in cooperation with the Heidelberg Academy of Sciences and Humanities/University of Tübingen a methodology was developed to model the spatial dispersion of volcanic deposits of Somma-Vesuvius volcanic complex since its Plinian eruption AD 79. Eventually, this was done to reconstruct the paleo-topography and paleo-environment of the Sarno River plain before the eruption AD 79. We collected, localized and digitized more than 1,800 core drillings to gain a representative network of stratigraphical information covering the entire plain. Besides other stratigraphical data including the characteristics of the pre-AD 79 stratum, the depth to the pre-AD 79 paleo-surface was identified from the available drilling documentation. Instead of applying a simple interpolation of the drilling data, we reconstructed the pre-AD 79 paleo-surface with a sophisticated geostatistical methodology using a machine based learning approach based on classification and regression trees. We hypothesize that the present-day topography reflects the ancient topography, because the eruption of AD 79 coated the ancient topography, leaving ancient physiographic elements of the Sarno River plain still recognizable in the present-day topography.

    This essay that examines the role of the volcano as a chemical site in the late eighteenth century, as the "new chemistry" spread throughout the southern Italian Kingdom of Naples, resulting in lively debates. In Naples itself, these scientific debates were not confined to academies, courts, and urban spaces. In the absence of well-equipped chemical laboratories, Neapolitan scholars also carried out research on chemistry on the slopes of Mount Vesuvius, a natural site that furnished them with all the tools and substances necessary for practising chemistry. By examining various Neapolitan publications on Vesuvius and the chemical reactions and products associated with its periodic eruptions, I argue that the volcano's presence contributed to a distinctive, local approach to chemical theory and practice. Several case studies examine the ways in which proximity to Vesuvius was exploited by Neapolitan scholars as they engaged with the new chemistry, including Giuseppe Vairo, Michele Ferrara, Francesco Semmola, and Emanuele Scotti.

    In this study we carried out a detailed lithostratigraphic, pedological and micromorphological analysis at a stratigraphic sequence close to Scafati, about 3 km east of ancient Pompeii. It consists of a multilayered succession of repeated volcanic deposition and pedogenesis caused by several phases of volcanic activity of Somma-Vesuvius and volcanic quiescence. This comprises, at least, the last 10,000 years of sedimentation history, on one hand, reflecting the entire spectrum of eruption types of Somma-Vesuvius from Plinian, sub-Plinian, rather small eruptions to effusive volcanic events and, on the other hand, soil formations of different durations, intensities and soil-forming environments. Furthermore, the paleosols repeatedly reveal clear evidence of anthropogenic activity by means of agriculture. Hence, a landscape evolution model was developed trying to reconstruct the last 10,000 years of volcanic activity, soil formation and land use in the hinterland of Pompeii.

    The current paradigm for volcanic eruptions is that magma erupts from a deep magma reservoir through a volcanic conduit, typically modelled with fixed rigid geometries such as cylinders. This simplistic view of a volcanic eruption does not account for the complex dynamics that usually characterise a large explosive event. Numerical simulations of magma flow in a conduit combined with volcanological and geological data, allow for the first description of a physics-based model of the feeding system evolution during a sustained phase of an explosive eruption. The method was applied to the Plinian phase of the Pomici di Avellino eruption (PdA, 3945 ±10 cal yr BP) from Somma-Vesuvius (Italy). Information available from volcanology, petrology, and lithology studies was used as input data and as constraints for the model. In particular, Mass Discharge Rates (MDRs) assessed from volcanological methods were used as target values for numerical simulations. The model solutions, which are non-unique, were constrained using geological and volcanological data, such as volume estimates and types of lithic components in the fall deposits. Three stable geometric configurations of the feeding system (described assuming elliptical cross-section of variable dimensions) were assessed for the Eruptive Units 2 and 3 (EU2, EU3), which form the magmatic Plinian phase of PdA eruption. They describe the conduit system geometry at time of deposition of EU2 base, EU2 top, and EU3. A 7-km deep dyke (length 2 a = 200-4 00 m, width 2 b = 10- 12 m), connecting the magma chamber to the surface, characterised the feeding system at the onset of the Plinian phase (EU2 base). The feeding system rapidly evolved into hybrid geometric configuration, with a deeper dyke (length 2 a = 600- 800 m, width 2 b = 50 m) and a shallower cylindrical conduit (diameter D = 50 m, dyke-to-cylinder transition depth ∼2100 m), during the eruption of the EU2 top. The deeper dyke reached the dimensions of 2 a = 2000 m and

    Volcanic ash causes multiple hazards. One hazard of increasing importance is the threat posed to civil aviation, which occurs over proximal to long-range distances. Ash fallout disrupts airport operations, while the presence of airborne ash at low altitudes near airports affects visibility and the safety of landing and take-off operations. Low concentrations of ash at airplane cruise levels are sufficient to force re-routing of in-flight aircrafts. Volcanic fallout deposits spanning large distances have been recognized from the Somma-Vesuvius volcano for several Holocene explosive eruptions. Here we develop hazard and isochron maps for distal ash fallout from the Somma-Vesuvius, as well as hazard maps for critical ash concentrations at relevant flight levels. Maps are computed by coupling a meteorological model with a fully numeric tephra dispersal model that can account for ash aggregation processes, which are relevant to the dispersion dynamics of fine ash. The simulations were carried out using supercomputing facilities, spanning on entire meteorological year that is statistically representative of the local meteorology during the last few decades. Seasonal influences are also analyzed. The eruptive scenario is based on a Subplinian I-type eruption, which is within the range of the maximum expected event for this volcano. Results allow us to quantify the impact that an event of this magnitude and intensity would have on the main airports and aerial corridors of the Central Mediterranean Area.

    Long-range dispersal of volcanic ash can disrupt civil aviation over large areas, as occurred during the 2010 eruption of Eyjafjallajökull volcano in Iceland. Here we assess the hazard for civil aviation posed by volcanic ash from a potential violent Strombolian eruption of Somma-Vesuvius, the most likely scenario if eruptive activity resumed at this volcano. A Somma-Vesuvius eruption is of concern for two main reasons: (1) there is a high probability (38 %) that the eruption will be violent Strombolian, as this activity has been common in the most recent period of activity (between AD 1631 and 1944); and (2) violent Strombolian eruptions typically last longer than higher-magnitude events (from 3 to 7 days for the climactic phases) and, consequently, are likely to cause prolonged air traffic disruption (even at large distances if a substantial amount of fine ash is produced such as is typical during Vesuvius eruptions). We compute probabilistic hazard maps for airborne ash concentration at relevant flight levels using the FALL3D ash dispersal model and a statistically representative set of meteorological conditions. Probabilistic hazard maps are computed for two different ash concentration thresholds, 2 and 0.2 mg/m3, which correspond, respectively, to the no-fly and enhanced procedure conditions defined in Europe during the Eyjafjallajökull eruption. The seasonal influence of ash dispersal is also analysed by computing seasonal maps. We define the persistence of ash in the atmosphere as the time that a concentration threshold is exceeded divided by the total duration of the eruption (here the eruption phase producing a sustained eruption column). The maps of averaged persistence give additional information on the expected duration of the conditions leading to flight disruption at a given location. We assess the impact that a violent Strombolian eruption would have on the main airports and aerial corridors of the Central Mediterranean area, and this assessment

    A new archaeological site of Roman Age has been recently found engulfed in the products of Vesuvius activity at Somma Vesuviana, on the northern flank of the Somma-Vesuvius, 5 km from the vent. A 9 m deep, 30 by 35 m trench has revealed a monumental edifice tentatively attributed to the Emperor Augustus. Different than Pompeii and Herculaneum sites which were completely buried in the catastrophic eruption of 79 AD, this huge roman villa survived the effects of the 79 AD plinian eruption as suggested by stratigraphic and geochronologic data. It was later completely engulfed in the products of numerous explosive volcanic eruptions ranging from 472 AD to 1631 AD, which were separated by reworked material and paleosols. The exposed burial sequence is comprised of seven stratigraphic units. Four units are composed exclusively of pyroclastic products each emplaced during a unique explosive event. Two units are composed of volcaniclastic material (stream flow and lahars) emplaced during quiescent periods of the volcano. Finally, one unit is composed of both pyroclastic and volcaniclastic deposits. One of the more relevant volcanological results of this study is the detailed reconstruction of the destructive events that buried the Emperor Augustus' villa. Stratigraphic evidence shows the absence of any deposit associated with the 79 AD eruption at this site and that the building was extensively damaged (sacked) before it was engulfed by the products of subsequent volcanic eruptions and lahars. The products of the 472 AD eruption lie directly on the roman structures. They consist of scoria fall layers intercalated with massive and stratified pyroclastic density current deposits that caused limited damage to the structure. The impact on the building of penecontemporaneous lahars was more important; these caused the collapse of some structures. The remaining part of the building was subsequently entombed by the products of explosive eruptions (e.g. 512/536 eruption, 1631

    New major and trace element analyses and Sr-isotope determinations of rocks from Mt. Somma-Vesuvius volcano produced from 25 ky BP to 1944 AD are part of an extensive database documenting the geochemical evolution of this classic region. Volcanic rocks include silica undersaturated, potassic and ultrapotassic lavas and tephras characterized by variable mineralogy and different crystal abundance, as well as by wide ranges of trace element contents and a wide span of initial Sr-isotopic compositions. Both the degree of undersaturation in silica and the crystal content increase through time, being higher in rocks produced after the eruption at 472 AD (Pollena eruption). Compositional variations have been generally thought to reflect contributions from diverse types of mantle and crust. Magma mixing is commonly invoked as a fundamental process affecting the magmas, in addition to crystal fractionation. Our assessment of geochemical and Sr-isotopic data indicates that compositional variability also reflects the influence of crustal contamination during magma evolution during upward migration to shallow crustal levels and/or by entrapment of crystal mush generated during previous magma storage in the crust. Using a variant of the assimilation fractional crystallization model (Energy Conservation-Assimilation Fractional Crystallization; [Spera and Bohrson, 2001. Energy-constrained open-system magmatic processes I: General model and energy-constrained assimilation and fractional crystallization (EC-AFC) formulation. J. Petrol. 999-1018]; [Bohrson, W.A. and Spera, F.J., 2001. Energy-constrained open-system magmatic process II: application of energy-constrained assimilation-fractional crystallization (EC-AFC) model to magmatic systems. J. Petrol. 1019-1041]) we estimated the contributions from the crust and suggest that contamination by carbonate rocks that underlie the volcano (2 km down to 9-10 km) is a fundamental process controlling magma compositions at Mt. Somma-Vesuvius

    The eruptive history of Mt. Somma-Vesuvius is characterised by large explosive events: Pomici di Base eruption (22,030 ± 175 yr cal BP), Mercato (8890 ± 90 yr cal BP), Avellino (3945 ± 10 yr cal BP) and Pompeii (79 AD). Pre-eruptive conditions and sin-eruptive degassing processes of the Avellino eruption, the highest-magnitude Plinian event, have been investigated, using volatile contents (F, Cl, H2O) in melt inclusions and residual glass, and textural characteristics of pumice clasts of the 9 fallout layers sampled in detail in a representative sequence. The sequence displays an up-section sharp colour change from white to grey, corresponding to variations in both magma composition and textural characteristics. The pre-eruptive conditions have been constrained by systematic measurements of Cl content in both melt inclusions and matrix glass of pumice clasts. The pumice glass composition varies from Na-rich phonolite (white pumice) to K-rich phonolite (grey pumice). The measured Cl values constantly cluster at 5200 ± 400 ppm (buffer value), whatever the composition of the melt, suggesting that the entire magma body was saturated with sub-critical fluids. This Cl saturation constrains the pre-eruptive pressures and maximum H2O contents at 200 ± 10 MPa and 6.3 ± 0.2 wt.% H2O for the white pumice melt and 195 ± 15 MPa and 5.2 ± 0.2 wt.% H2O for the grey pumice melt. The fluid phase, mainly composed of a H2O-rich vapour phase and brine, probably accumulated at the top of the reservoir and generated an overpressure able to trigger the onset of the eruption. Magma degassing was rather homogeneous for the white and grey eruptive units, mostly occurring through closed-system processes, leading to a typical Plinian eruptive style. A steady-state withdrawal of an H2O-saturated magma may explain the establishment of a sustained Plinian column. Variation from white to grey pumice is accompanied by decrease of mean vesicularity and increase of mean microcrystallinity

    Rainfall-induced debris flows involving ash-fall pyroclastic deposits that cover steep mountain slopes surrounding the Somma-Vesuvius volcano are natural events and a source of risk for urban settlements located at footslopes in the area. This paper describes experimental methods and modelling results of shallow landslides that occurred on 5–6 May 1998 in selected areas of the Sarno Mountain Range. Stratigraphical surveys carried out in initiation areas show that ash-fall pyroclastic deposits are discontinuously distributed along slopes, with total thicknesses that vary from a maximum value on slopes inclined less than 30° to near zero thickness on slopes inclined greater than 50°. This distribution of cover thickness influences the stratigraphical setting and leads to downward thinning and the pinching out of pyroclastic horizons. Three engineering geological settings were identified, in which most of the initial landslides that triggered debris flows occurred in May 1998 can be classified as (1) knickpoints, characterised by a downward progressive thinning of the pyroclastic mantle; (2) rocky scarps that abruptly interrupt the pyroclastic mantle; and (3) road cuts in the pyroclastic mantle that occur in a critical range of slope angle. Detailed topographic and stratigraphical surveys coupled with field and laboratory tests were conducted to define geometric, hydraulic and mechanical features of pyroclastic soil horizons in the source areas and to carry out hydrological numerical modelling of hillslopes under different rainfall conditions. The slope stability for three representative cases was calculated considering the real sliding surface of the initial landslides and the pore pressures during the infiltration process. The hydrological modelling of hillslopes demonstrated localised increase of pore pressure, up to saturation, where pyroclastic horizons with higher hydraulic conductivity pinch out and the thickness of pyroclastic mantle reduces or is

    Public works in progress in the Campanian plain north of Somma-Vesuvius recently encountered the remains of a prehistoric settlement close to the town of Afragola. Rescue excavations brought to light a Bronze Age village partially destroyed and buried by pyroclastic density currents (PDCs) of the Vesuvian Pomici di Avellino eruption (3.8 14C ka BP) and subsequently sealed by alluvial deposits. Volcanological and rock-magnetic investigations supplemented the excavations. Careful comparison between volcanological and archaeological stratigraphies led to an understanding of the timing of the damage the buildings suffered when they were struck by a series of PDCs. The first engulfed the village, located some 14 km to the north of the inferred vent, and penetrated into the dwellings without causing major damage. The buildings were able to withstand the weak dynamic pressure of the currents and deviate their path, as shown by the magnetic fabric analyses. Some later collapsed under the load of the deposits piled up by successive currents. Stepwise demagnetization of the thermal remanent magnetization (TRM) carried by potsherds embedded in the deposits yields deposition temperatures in the order of 260-320 °C, fully consistent with those derived from pottery and lithic fragments from other distal and proximal sites. The fairly uniform temperature of the deposits is here ascribed to the lack of pervasive air entrainment into the currents. This, in turn, resulted from the lack of major topographical obstacles along the flat plain. The coupling of structural damage and sedimentological analyses indicates that the currents were not destructive in the Afragola area, but TRM data indicate they were still hot enough to cause death or severe injury to humans and animals. The successful escape of the entire population is apparent from the lack of human remains and from thousands of human footprints on the surface of the deposits left by the first PDCs. People were thus able to

    2013-11-01

    Full Text Available Mt. Vesuvius (southern Italy is one of the most hazardous volcanoes in the world. Its activity is currently characterized by moderate seismicity, with hypocenters located beneath the crater zone with depth rarely exceeding 5 km and magnitudes generally less than 3. The current configuration of the seismic monitoring network of Mt. Vesuvius consists of 18 seismic stations and 7 infrasound microphones. During the period 2006-2010 a seismic array with 48 channels was also operative. The station distribution provides appropriate coverage of the area around the volcanic edifice. The current development of the network and its geometry, under conditions of low seismic noise, allows locating seismic events with M<1. Remote instruments continuously transmit data to the main acquisition center in Naples. Data transmission is realized using different technological solutions based on UHF, Wi-Fi radio links, and TCP/IP client-server applications. Data are collected in the monitoring center of the Osservatorio Vesuviano (Italian National Institute of Geophysics and Volcanology, Naples section, which is equipped with systems for displaying and analyzing signals, using both real-time automatic and manual procedures. 24-hour surveillance allows to immediately communicate any significant anomaly to the Civil Protection authorities.

    In this study the methodology proposed by Vogel & Märker (2010) to reconstruct the pre-AD 79 topography and paleo-environmental features of the Sarno River plain (Italy) was considerably revised and improved. The methodology is based on an extensive dataset of stratigraphical information from the entire Sarno River plain, a high-resolution present-day digital elevation model (DEM) and a classification and regression tree approach. The dataset was re-evaluated and 32 additional stratigraphical drillings were collected in areas that were not or insufficiently covered by previous stratigraphic data. Altogether, an assemblage of 1,840 drillings, containing information about the depth from the present-day surface to the pre-AD 79 paleo-surface (thickness of post-AD 79 deposits) and the character of the pre-AD 79 paleo-layer of the Sarno River plain was utilized. Moreover, an improved preprocessing of the input parameters attained a distinct progress in model performance in comparison to the previous model of Vogel & Märker (2010). Subsequently, a spatial model of the post-AD 79 deposits was generated. The modelled deposits were then used to reconstruct the pre-AD 79 topography of the Sarno River plain. Moreover, paleo-environmental and paleo-geomorphological features such as the paleo-coastline, the paleo-Sarno River and its floodplain, alluvial fans near the Tyrrhenian coast as well as abrasion terraces of historical and protohistorical coastlines were identified. This reconstruction represents a qualitative improvement of the previous work by Vogel & Märker (2010).

    A survey on fibrous minerals coming from the densely populated area of Campania around the Somma-Vesuvius volcanic complex (Italy) was performed by means of a multi-methodological approach, based on morphological analyses, EMPA/WDS and SEM/EDS applications, and unit-cell determination through X-ray diffraction data. Such mineralogical investigation aims to provide suitable tools to the identification of fibrous natural phases, to improve the knowledge of both geochemical, petrogenetic and regional mineralogy of Somma-Vesuvius area, and to emphasize the presence of minerals with fibrous habit in all volcanic environments. The survey also fits well in the calls of health and environment of Horizon 2020 program of the European Commission (Climate Action, Environment, Resource Efficiency and Raw Materials).

    We analyzed new magnetic, bathymetric, and seismic data acquired in the offshore sector of Somma-Vesuvius volcano (Italy). We detected a group of high-intensity, short wavelength magnetic anomalies corresponding to partly buried volcanic dome-like structures located by seismic data. The magnetic anomalies are aligned along a NW-SE strike that is the preferential orientation of an eruptive fracture of the pre-19 ka activity of Vesuvius. Three cones emplaced before the Last Glacial Maximum, whereas a fourth one emplaced after 19 ka suggesting a rejuvenation of the eruptive system offshore the volcano in historical times. We also identified a NE-SW elongated magnetic anomaly consistent with a dike-like body associated to an on-land tectonic structure that was active in recent times at Vesuvius. A delta-like area with diffuse low-intensity magnetic anomalies reflects the seaward fronts of lava flows that entered the sea mainly during the Middle Ages.

    A large database of major, trace and isotope (Sr, Nd, Pb, O) data exists for rocks produced by the volcanic activity of Somma-Vesuvius volcano. Variation diagrams strongly suggest a major role for evolutionary processes such as fractional crystallization, contamination, crystal trapping and magma maxing, occurring after magma genesis in the mantle. Most mafic magmas are enriched in LILE (Light Ion Lithophile Elements; K. Rb, Ba), REE (Ce, Sm) and Y, show small Nb-Ta negative anomalies, and have values of Nb/Zr at about 0.15. Enrichments in LILE, REE, Nb and Ta do not correlate with Sr isotope values or degree of both K enrichment and silica undersaturation. The results indicate mantle source heterogeneity produced by slab-derived components beneath the volcano. However, the Sr isotope values of Somma-Vesuvius increase from 0.7071 up to 0.7081 with transport through the uppermost 11-12 km of the crust. The Sr isotope variation suggests that the crustal component affected the magmas during ascent through the lithosphere to the surface. Our new geochemical assessment based on chemical, isotopic and fluid inclusion data points to the existence of three main levels of magma storage. Two of the levels are deep and may represent long-lived reservoirs; the uppermost crustal level probably coincides with the volcanic conduit. The deeper level of magma storage is deeper than 12 km and fed the 1944 AD eruption. The intermediate level coincides with the seismic discontinuity detected by Zollo et al. (1996) at about 8 km. This intermediate level supplies magmas with 87Sr/86Sr values between 0.7071 and 0.7074, and ??O18<8% that typically erupted both during interplinian (i.e. 1906 AD) and sub-plinian (472 AD, 1631 AD) events. The shallowest level of magma storage at about 5 km was the site of magma chambers for the Pompei and Avellino plinian eruptions. New investigations are necessary to verify the proposed magma feeding system. ?? 2006 Elsevier B.V. All rights reserved.

Italy had 57.3 million persons in 1986, with a growth rate of 2.3%. The life expectancy is 73 years; the infant mortality rate is 14.3/1000 live births. 98% of the people are literate. The current constitutional republic has existed since 1948. Mean per capita income is $6,447. The people work mainly in services (60%), industry (30%) and agriculture (10%). Most of the country is mountainous, without significant food, energy or natural resources, so Italy's central position in the Mediterranean has influenced economic development since ancient times. The nation is highly homogeneous, as the government is centralized. Although there are several influential political parties, the diverse structure of the Christian Democrats has given them power since the war. The current prime minister, Bettino Craxi, is a member of the centralist Italian Socialist Party. The Italian Communist Party is the largest such party in the free world, polling 30% of the vote in 1983. Italy is a member of NATO.

    Full Text Available In this paper we present and discuss the results of a geophysical airborne survey carried out in the Somma-Vesuvius volcanic area, Southern Italy, in 1999. The helicopter-borne survey was aimed at giving new detailed insights into the distribution of the magnetization of the area and, therefore, into the volcanological characteristics of the region, enhancing the knowledge given by a previous low resolution survey carried out at a regional scale by Agip. The new survey was carried out by flying on a surface parallel to the topography of the area, along flight lines spaced 600 m apart. The obtained total field map is dominated by a large anomaly related to the Mt. Somma-Vesuvius complex itself and characterized by a roughly elliptical shape. High-frequency anomalies occur in the edifice and in the area east of it, partly produced by cultural noise due to the densely inhabited area. The compilation of the maps of the analytic signal and of the horizontal derivative of the field allowed the location of the lateral boundaries of the magnetic sources of the area and represents a first step toward the interpretation of the maps in terms of geological structures.

    Somma-Vesuvius is a quiescent strato-volcano of the Neapolitan district, southern Italy, for which various geophysical and geological evidences (e.g. geodetic measurements, geological and structural data, seismic profiles interpretations and surface deformation analysis with Differential Interferometric Synthetic Aperture Radar (DInSAR)) indicate ongoing spreading deformation. In this research we investigate the spreading deformation and associated surface deformation pattern by performing analogue experiments and comparing the results with actual ground deformation as measured using DInSAR data recorded between 1992 and 2010. Somma-Vesuvius consists of a volcanic cone (Gran Cono) lying within an asymmetric caldera (Somma). The Somma caldera is the result of at least 7 Plinian eruptions, the last of which was the 79 CE. Pompeii eruption. The current cone of Mt. Vesuvius grew within the caldera in the following centuries as the effect of continued explosive and effusive activity of the volcano. The volcano lies on a substratum consisting of a Mesozoic carbonatic basement, overlapped by Holocene clastic sediments and volcanic rocks. Our analogue models were built to simulate the shape of the Somma-Vesuvius top a scale of about 1:100000, emplaced on a sand layer (brittle behaviour) laid on a silicone layer (ductile behaviour). Models are based on the Fluid-dynamics Dimensionless Analysis (FDA), according to the Buckingham-Π theorem. In this context, we considered few dimensionless parameters that allowed the setting of a reliable scaled model. To represent the complex Somma-Vesuvius geometry, an asymmetric model was built by setting a truncated cone (mimicking the topography of Somma edifice) topped by another small cone (mimicking the Gran Cono) shifted off the axis of the main cone. Different experiments were carried out in which the thickness of the basal sand layer and of the silicone one were varied. To quantify the vertical and horizontal displacements the

    The museum of Vesuvius Observatory was created through the enlargement and updating of a permanent exhibition called "Vesuvius: 2000 years of observations", set up in 2000 with the aim of make citizens aware of volcanic phenomena, volcanic hazard and surveillance of active volcanoes in high risk areas, such as Naples and surroundings. The museum is located in the nineteenth-century historical building of the Vesuvius Observatory, the first volcanological observatory in the world, currently part of the National Institute of Geophysics and Volcanology. In the museum the dominant theme is the volcano Vesuvius: along the exhibition scientific issues are strictly interlaced with historical, archaeological and literary topics. The exhibition path begins with the presentation of eruptive phenomena, and related hazard for people and things. It traces the eruptive history of Somma-Vesuvius pointing out the most famous eruptions, occurred in 79 AD and 1944, and the methodologies used by volcanologists to define the eruptive history of a volcano through the study of its products. In the octagonal room the products of effusive and explosive eruptions, and minerals formed in volcanic environments, are displayed. The path, consisting of panels and video on big screen, is enriched by the exhibition of historical documents as the geological map of Somma-Vesuvius by Henry James Johnston-Lavis and of copies of Ercolano and Pompeii casts. Also historical scientific instruments once used for surveillance are on display, including the first electromagnetic seismograph, built in 1856 by Luigi Palmieri, director of the Vesuvius Observatory from 1855 to 1896. The tour ends with a practical experience of simulation of an earthquake. Communication tools used in the museum are basically video and panels. The museum admission is free; visitors enter the museum by guided tours only. Since the year 2000 checking of visiting public was carried out, either through booking requests received by the

    We present and discuss the results of an integrated electrical and electromagnetic survey in the active volcanic area of Mount Somma-Vesuvius (Naples, Italy). Dipolar geoelectrics (DG), self-potential (SP) and magnetotellurics (MT) were used to investigate the shallow and deep regions of the volcanic area. The DG apparent resistivity pseudosection along a N-S profile across the Vesuvius cone showed the existence of a largely extended conductive zone, closely in correspondence to the Somma caldera, including in the middle the top terminal part of the Vesuvius main plumbing system. The SP data, collected over the whole volcanic area, showed the existence of a W-E-directed wide band of weak positive anomalies, indicating again a conductive zone, not only including the whole Somma caldera but also extending towards the Tyrrhenian sea. A roughly N-S-trending narrow fracture system, cutting the lowest Mount Somma eastern slopes, was further evident from the SP data. A new SP tomographic inversion procedure allowed to detect a large positively charged nucleus in the depth range 600-2200 m b.g.l., located beneath the westernmost portion of a former caldera, related to the Avellino plinian eruption. The geophysical interpretation of this large positive anomaly was made using Onsager's theory of coupled electrokinetic and thermoelectric flows. The final interpretation was that the shallow, conductive central zone is very likely made up of an intensively altered and mineralised block of cemented volcanic breccia. Finally, the MT data, distributed along two perpendicular profiles, enabled us to obtain the first significant picture of the deep electrical structure of the volcano. The Bostick inversion revealed the existence of a conductive intracrustal layer, including a perched more conductive zone located roughly beneath the central-western sector of the Vesuvius apparatus.

    High-resolution seismic reflection data are used to identify structural features in Naples Bay near Vesuvius Volcano. Several buried seismic units with reflection-free interiors are probably volcanic deposits erupted during and since the formation of the breached crater of Monte Somma Volcano, which preceded the growth of Vesuvius. The presumed undersea volcanic deposits are limited in extent; thus, stratigraphie relationships cannot be established among them. Other features revealed by our data include (a) the warping of lowstand marine deposits by undersea cryptodomes located approximately 10 km from the summit of Vesuvius, (b) a succession of normal step faults that record seaward collapse of the volcano, and (c) a small undersea slump in the uppermost marine deposits of Naples Bay, which may be the result of nue??e ardentes that entered the sea during a major eruption of Vesuvius in 1631. Detection of these undersea features illustrates some capabilities of making detailed seismic reflection profiles across undersea volcanoes.

    Volcanic eruptions pose significant hazards to human populations and have the potential to cause significant economic impacts as shown by the recent ash-producing eruptions in Iceland. Demonstrating both the local and global impact of eruptions is important for developing an appreciation of the scale of hazards associated with volcanic activity. In order to address this need, Web-based virtual field exercises at Vesuvius volcano in Italy and Laki volcano in Iceland have been developed as curriculum enhancements for undergraduate geology classes. The exercises are built upon previous research by the authors dealing with the 79 AD explosive eruption of Vesuvius and the 1783 lava flow eruption of Laki. Quicktime virtual reality images (QTVR), video clips, user-controlled Flash animations and interactive measurement tools are used to allow students to explore archeological and geological sites, collect field data in an electronic field notebook, and construct hypotheses about the impacts of the eruptions on the local and global environment. The QTVR images provide 360o views of key sites where students can observe volcanic deposits and formations in the context of a defined field area. Video sequences from recent explosive and effusive eruptions of Carribean and Hawaiian volcanoes are used to illustrate specific styles of eruptive activity, such as ash fallout, pyroclastic flows and surges, lava flows and their effects on the surrounding environment. The exercises use an inquiry-based approach to build critical relationships between volcanic processes and the deposits that they produce in the geologic record. A primary objective of the exercises is to simulate the role of a field volcanologist who collects information from the field and reconstructs the sequence of eruptive processes based on specific features of the deposits. Testing of the Vesuvius and Laki exercises in undergraduate classes from a broad spectrum of educational institutions shows a preference for the

This theoretical approach has been achieved within the activities of the EXPLORIS Project supported by the EU.

    We present new mineral chemistry, fluid inclusion, stable carbon and oxygen, as well as Pb, Sr, and Nd isotope data of Ca-Mg-silicate-rich ejecta (skarns) and associated cognate and xenolithic nodules from the Mt. Somma-Vesuvius volcanic complex, Italy. The typically zoned skarn ejecta consist mainly of diopsidic and hedenbergitic, sometimes "fassaitic" clinopyroxene, Mg-rich and Ti-poor phlogopite, F-bearing vesuvianite, wollastonite, gehlenite, meionite, forsterite, clinohumite, anorthite and Mg-poor calcite with accessory apatite, spinell, magnetite, perovskite, baddeleyite, and various REE-, U-, Th-, Zr- and Ti-rich minerals. Four major types of fluid inclusions were observed in wollastonite, vesuvianite, gehlenite, clinopyroxene and calcite: a) primary silicate melt inclusions (THOM = 1000-1050??C), b) CO2 ?? H2S-rich fluid inclusions (THOM = 20-31.3??C into the vapor phase), c) multiphase aqueous brine inclusions (THOM = 720-820??C) with mainly sylvite and halite daughter minerals, and d) complex chloride-carbonate-sulfate-fluoride-silicate-bearing saline-melt inclusions (THOM = 870-890??C). The last inclusion type shows evidence for immiscibility between several fluids (silicate melt - aqueous chloride-rich liquid - carbonate/sulfate melt?) during heating and cooling below 870??C. There is no evidence for fluid circulation below 700??C and participation of externally derived meteoric fluids in skarn formation. Skarns have considerably variable 206Pb/204Pb (19.047-19.202), 207Pb/204Pb (15.655-15.670), and 208Pb/204Pb (38.915-39.069) and relatively low 143Nd/144Nd (0.51211-0.51244) ratios. The carbon and oxygen isotope compositions of skarn calcites (??13CV-PDB = -5.4 to -1.1???; ??18OV-SMOW = 11.7 to 16.4???) indicate formation from a 18O- and 13C-enriched fluid. The isotope composition of skarns and the presence of silicate melt inclusion-bearing wollastonite nodules suggests assimilation of carbonate wall rocks by the alkaline magma at moderate depths (< 5

    Spera, Frank

    The Roman population centers of Pompeii and Herculaneum (circa 15,000 inhabitants) were destroyed when Mount Vesuvius erupted in 79 A.D. after centuries of repose. Many times since then its eruptions have claimed human lives; basaltic lava flows from an eruption in 1631 killed 3,000. Vesuvius' location, near the heart of the Roman empire—a center of learning in the ancient world—led it to become the site ofsome of the earliest volcanological studies on record.In letters to Tacitus, Pliny the Younger documented the sequence of events of the 79 A.D. plinian eruption. Geophysical studies of volcanoes were pioneered by Italian volcanologists who installed seismographs in an observatory on the flanks of Vesuvius to study volcano seismology and to forecast and monitor eruptions early this century. It is easy to understand why interest in Vesuvius has been so keen: it is accessible, persistently active, and a large population resides nearby. Today, around 1 million people live within the shadow of this potentially explosive and dangerous volcano.

    A probabilistic approach based on the available volcanological data on past Somma-Vesuvius eruptions has been developed to produce hazard-zone maps for fallout, pyroclastic density currents (PDCs), and secondary mass flows by using numerical simulations. The hazard maps have been incorporated in a GIS, making them accessible to casual and expert users for risk mitigation and education management. The results allowed us to explore the hazard related to different scenarios from all possible eruptions, ranked according to volcanic explosivity index (VEI) class, in the Vesuvius area and its surroundings including Naples. Particularly, eruptions with VEI ≤ 3 would produce a fallout hazard within about 10 km mostly east of the volcano and a PDC hazard within about 2 km from the crater. Large-scale events (4 ≤ VEI ≤ 5) would produce a fallout hazard up to 80 km from the vent and a PDC hazard at distances exceeding 15 km. Particularly, the territory northwest of Vesuvius, including metropolitan Naples, featuring a low hazard level for fallout accumulation, is exposed to PDCs also consistent with field evidence and archeological findings. Both volcano flanks and surrounding plains, hills, and mountains are exposed to a moderate-high level of hazard for the passage of secondary mass flows. With the present level of uncertainty in forecasting future eruption type and size on the basis of statistical analysis as well as precursory activity, our results indicate that the reference scenario in the emergency plan should carefully match the worst-case VEI 5 probabilistic scenario.

    Detailed micropalaeontological and petrochemical analyses of rock samples from two boreholes drilled at the archaeological excavations of Herculaneum, ~ 7 km west of the Somma -Vesuvius crater, allowed reconstruction of the Late Quaternary palaeoenvironmental evolution of the site. The data provide clear evidence for ground uplift movements involving the studied area. The Holocenic sedimentary sequence on which the archaeological remains of Herculaneum rest has risen several meters at an average rate of ~ 4 mm/yr. The uplift has involved the western apron of the volcano and the Sebeto-Volla Plain, a populous area including the eastern suburbs of Naples. This is consistent with earlier evidence for similar uplift for the areas of Pompeii and Sarno valley (SE of the volcano) and the Somma -Vesuvius eastern apron. An axisimmetric deep source of strain is considered responsible for the long-term uplift affecting the whole Somma -Vesuvius edifice. The deformation pattern can be modeled as a single pressure source, sited in the lower crust and surrounded by a shell of Maxwell viscoelastic medium, which experienced a pressure pulse that began at the Last Glacial Maximum.

    Mt. Somma-Vesuvius (Naples, Italy) has erupted potassium-rich and silica-undersaturated products during a complicated history of plinian and non-plinian events. Coarse-grained cognate nodules are commonly found in the pyroclastics and are upper crustal in origin. We examined cumulate and subeffusive nodules from the 3800 y.B.P. Avellino. A.D. 79 Pompei, and A.D. 472 Pollena eruptions. Silicate-melt and liquid-vapor fluid inclusion studies in clinopyroxene from both types of nodules have been used to assess the fluids attending crystallization and to place constraints on the pressure and temperature of nodule formation. Thermometric and volumetric data from primary and pseudosecondary CO2-H2O and CO2 and coeval silicate-melt fluid inclusions indicate that they were trapped at a pressure of ???1 to ???2.5 kbar at ???1200??C. This suggests a crystallization depth of ???4 to ???10 km. The H2O-bearing fluid inclusions are abundant from plinian eruptions in contrast to non-plinian eruptions where H2O-bearing fluid inclusions were rare. The presence of primary H2O-CO2 fluid inclusions indicates that an immiscible, supercritical H2O-CO2 fluid was in the nodule-forming environment. The H2O-bearing fluid inclusions in plinian nodules may record a higher pre-eruptive H2O content in the bulk magma that is dramatically reflected in the eruption dynamics. ?? 1993.

    Pumice and scoria from different eruptive layers of Mt. Vesuvius volcanic products contain mafic minerals consisting of High-Fo olivine and Diopsidic Pyroxene. These phases were crystallized in unerupted trachibasaltic to tephritic magmas, and were brought to surface by large phonolitic/tephri-phonolitic (e.g. Avellino and Pompei) and/or of tephritic and phono-tephritic (Pollena) eruptions. A large set of these mm-sized crystals was accurately separated from selected juvenile material and measured for their chemical compositions (EPMA, Laser Ablation ICP-MS) and 18O/16O ratios (conventional laser fluorination) to constrain the nature and evolution of the primary magmas at Mt. Vesuvius. Uncontaminated mantle δ18O values are hardly recovered in Italian Quaternary magmas, mostly due to the widespread occurrence of crustal contamination of the primary melts during their ascent to the surface (e.g. Alban Hills, Ernici Mts., and Aeolian Islands). At Mt. Vesuvius, measured olivine and clinopyroxene share quite homogeneous chemical compositions (Olivine Fo 85-90 ; Diopside En 45-48, respectively), and represent phases crystallized in near primary mafic magmas. Trace element composition constrains the near primary nature of the phases. Published data on volatile content of melt inclusions hosted in these crystals reveal the coexistence of dissolved water and carbon dioxide, and a minimum trapping pressure around 200-300 MPa, suggesting that crystal growth occurred in a reservoir at about 8-10 km depth. Recently, experimental data have suggested massive carbonate assimilation (up to about 20%) to derive potassic alkali magmas from trachybasaltic melts. Accordingly, the δ18O variability and the trace element content of the studied minerals suggest possible contamination of primary melts by an O-isotope enriched, REE-poor contaminant like the limestone of Vesuvius basement. Low, nearly primitive δ18O values are observed for olivine from Pompeii eruption, although still

    Undegassed deep melts can be trapped as melt inclusions (MI) hosted in phenocrysts growing in magma reservoirs. The host crystal acts as a pressure capsule, ideally preventing the melt from degassing. Sometimes, MI often contain a vapor bubble when observed at ambient conditions. Bubble-bearing MI represent a natural sample with which to investigate magmatic fluids that directly exsolve from a silicate melt. Some recent studies reported that most of the CO2 in bubble-bearing MI hosted in mafic minerals is stored in the vapor bubble. However, despite the detection of CO2 in bubbles, the expected accompanying H2O has not been found in mafic MI hosted in olivine. In this presentation, we describe the discovery of H2O in MI hosted in olivine associated with the Mt. Somma-Vesuvius (Italy) magmas. We reheated crystallized (or partially crystallized) olivine-hosted MI from various eruptions at Mt. Somma-Vesuvius. We quenched bubble-bearing MI from high T (1143-1238°C) to produce a bubble-bearing glass at room T. Using Raman spectroscopy, we detected liquid H2O at room T, vapor H2O at 150°C in the vapor bubbles of reheated MI, and native S and gypsum, in addition to CO2. In most MI, the H2O is hosted in sub-micron scale hydrous phases at the interface between the bubble and the glass and would not be detected during routine analysis. During MI heating experiments, the H2O is redissolved into the melt and then exsolves from the melt into the vapor bubble, where it remains after quenching, at least on the relatively short time scales of our observations. Our results suggest that a significant amount of H2O may be stored in vapor bubbles of bubble-bearing MI, especially for MI with (1) relatively low H2O content in the originally trapped melt, (2) relatively high proportion of H2O in the exsolved fluid, (3) relatively large volume % vapor bubble. In addition, we calculated that the composition of magmatic fluids directly exsolving from mafic melts associated with Mt. Somma-Vesuvius

    Vertical ground movements at Somma-Vesuvius during the last glacial cycle have been inferred from micropalaeontological and petrochemical analyses of rock samples from boreholes drilled at the archaeological sites of Herculaneum and Pompeii as well as on the apron of the volcano and the adjacent Sebeto and Sarno Valleys. Opposing movements occurred during the periods preceding and following the Last Glacial Maximum (LGM). The uplift began 20 ka ago with marine deposits rising several tens of metres up to 25 m a.s.l., recovering previous subsidence which occurred during the Late glacial period, suggesting a strict connection between volcano-tectonic and glacial cycles. Here we present the analysis of deposits predating the LGM, which confirms subsidence of the Campanian Plain where Mt. Somma-Vesuvius is located, shows variable surface loading effects and highlights the volcano-tectonic stages experienced by the volcano. The self-balancing mechanism of the volcanic system, evolving towards an explosive, subaerial activity 60 ka ago, is testified to by a large ground oscillation in phase with sea level change during the last glacial cycle.

    Somma-Vesuvius is an alkaline volcano whose products (pumice, scoria and lava) have alkaline (Na2O+K2O) contents between 6 and 16 wt%, Mg number Somma-Vesuvius activity, except for the Ottaviano and Avellino plinian (0.8 wt%) events. Chlorine has a wider range, from 0.1 wt% to 1.6 wt%. Mt Somma-Vesuvius has some features similar to those of mineralized alkaline magmatic systems which coincide with the transition between subduction-related compression and extension-related to continental rifting. We infer that a prospective time for the formation of mineralization at Mt Somma-Vesuvius was during the 1631-1944 eruptive period.

    Full Text Available Magnetotelluric (MT soundings performed in the past in the volcanic area of Mt. Vesuvius by two independent research groups showed in the same places MT apparent resistivity curves with very similar shape, but statically shifted by one order of magnitude, at least. To try to resolve this ambiguity new controlled source audio-magnetotelluric (CSAMT measurements have been carried out in the same MT sites. The interpretation of the CSAMT dataset, combined with that of two shallow dipole-dipole geoelectrical resistivity tomographies previously carried out in the area have allowed a reliable electrical structure to be recovered down to a few km of depth, which will next be used for a best constrained re-interpretation of the deep MT soundings.

  2. Oxygen isotope composition of mafic magmas at Vesuvius

    The oxygen isotope composition of olivine and clinopyroxene from four plinian (AD 79 Pompeii, 3960 BP Avellino), subplinian (AD 472 Pollena) and violent strombolian (Middle Age activity) eruptions were measured to constrain the nature and evolution of the primary magmas of the last 4000 years of Mt. Vesuvius activity. A large set of mm-sized crystals was accurately separated from selected juvenile material of the four eruptions. Crystals were analyzed for their major and trace element compositions (EPMA, Laser Ablation ICP-MS), and for 18O/16O ratios. As oxygen isotope composition of uncontaminated mantle rocks on world-wide scale is well constrained (δ18Oolivine = 5.2 ± 0.3; δ18Ocpx = 5.6 ± 0.3 ‰), the measured values can be conveniently used to monitor the effects of assimilation/contamination of crustal rocks in the evolution of the primary magmas. Instead, typically uncontaminated mantle values are hardly recovered in Italian Quaternary magmas, mostly due to the widespread occurrence of crustal contamination of the primary magmas during their ascent to the surface (e.g. Alban Hills, Ernici Mts., and Aeolian Islands). Low δ18O values have been measured in olivine from Pompeii eruption (δ18Oolivine = 5.54 ± 0.03‰), whereas higher O-compositions are recorded in mafic minerals from pumices or scoria of the other three eruptions. Measured olivine and clinopyroxene share quite homogeneous chemical compositions (Olivine Fo 85-90 ; Diopside En 45-48, respectively), and represent phases crystallized in near primary mafic magmas, as also constrained by their trace element compositions. Data on melt inclusions hosted in crystals of these compositions have been largely collected in the past demonstrating that they crystallized from mafic melt, basaltic to tephritic in composition. Published data on volatile content of these melt inclusions reveal the coexistence of dissolved water and carbon dioxide, and a minimum trapping pressure around 200-300 MPa, suggesting

    Clinopyroxene and olivine are ubiquitous phases in Somma-Vesuvius (SV) volcanics and for the first time they were systematically studied in several products younger than 40 ka. In this manuscript chemical compositions (major, trace and rare earth elements) of a large set of olivine and clinopyroxene crystals from selected rock samples are presented and discussed. Fourteen pumice samples from Plinian pyroclastic deposits as well as three scoriae and eight lava samples from inter-Plinian deposits were collected. A representative number of olivine and clinopyroxene crystals (n 50) were selected for each sample and analysed by electron microprobe and laser ablation inductively coupled plasma mass spectrometer, resulting in a large database, which is now available to the scientific community. All studied eruptive products contain olivine and clinopyroxene crystals spanning a wide range of compositions. Olivines show Fo content varying from 91 to 68, while clinopyroxenes display Mg# ranging from 93 to 71. In samples younger than A.D. 79, the more evolved (Mg#82-72) clinopyroxene crystals show clear Ca enrichment ( 23.5-24.5 wt% CaO) with respect to those from older samples (before-A.D.79, 23-21 wt% CaO). The results corroborate disequilibrium between olivine, clinopyroxene and the hosting melt, and an increasing role of carbonate assimilation in SV magma evolution in the last 2 ka. The database here produced is thought as a share product that makes available mineral data and can be used for further studies by researchers to investigate geochemical evolution of the SV system.

    The contribution focuses on the current status of the ESA study entitled "INSARAP Sentinel-1 Constellation Study" and investigates the interferometric performance of the S1A/S1B units. In particular, we refer to the Vesuvius/Campi Flegrei (Southern Italy) volcanic test site, where the continuous inflation (about 35 cm from 2011 to date) and the huge availability of ground-based geodetic data (continuous GPS - cGPS - leveling, tiltmetric, gravimetric, etc.) from the INGV-Osservatorio Vesuviano monitoring networks have allowed to get a clear deformation signal, besides the comparison between S1A/S1B and geodetic data. In this regard, the integration between InSAR and geodetic measurements is crucial for a continuous and extended monitoring of such an active volcanic area, as InSAR investigations allow to get an information on wide areas, whereas permanent networks (e.g., cGPS), allow to provide a continuous information complementing InSAR, which is limited by its revisiting time. Comparisons between S1 constellation data and geodetic measurements, with a particular focus on cGPS, will be presented, exploiting both LOS and inverted (E-W and vertical inversion) InSAR data starting from October, 2014. In addition, as a next step we are planning to model the deformation source of the area by exploiting the S1 time series results. Ultimately, very encouraging results suggest for a continuation of this activity also for the future, showing the great potential of S1 constellation data for monitoring active volcanic areas and, in general, to retrieve a very high quality deformation signal.

  6. Simulation of tsunamis induced by volcanic activity in the Gulf of Naples (Italy

    2003-01-01

    Full Text Available The paper explores the potential of tsunami generation by pyroclastic flows travelling down the flank of the volcano Vesuvius that is found south of Naples in Italy. The eruption history of Vesuvius shows that it is characterised by large explosive eruptions of plinian or subplinian type during which large volume of pyroclastic flows can be produced. The most remarkable examples of such eruptions occurred in 79 AD and in 1631 and were catastrophic. Presently Vesuvius is in a repose time that, according to volcanologists, could be interrupted by a large eruption, and consequently proper plans of preparedness and emergency management have been devised by civil authorities based on a scenario envisaging a large eruption. Recently, numerical models of magma ascent and of eruptive column formation and collapse have been published for the Vesuvius volcano, and propagation of pyroclastic flows down the slope of the volcanic edifice up to the close shoreline have been computed. These flows can reach the sea in the Gulf of Naples: the denser slow part will enter the waters, while the lighter and faster part of the flow can travel on the water surface exerting a pressure on it. This paper studies the tsunami produced by the pressure pulse associated with the transit of the low-density phase of the pyroclastic flow on the sea surface by means of numerical simulations. The study is divided into two parts. First the hydrodynamic characteristics of the Gulf of Naples as regards the propagation of long waves are analysed by studying the waves radiating from a source that is a static initial depression of the sea level localised within the gulf. Then the tsunami produced by a pressure pulse moving from the Vesuvius toward the open sea is simulated: the forcing pulse features are derived from the recent studies on Vesuvian pyroclastic flows in the literature. The tsunami resulting from the computations is a perturbation involving the whole Gulf of Naples, but it

    Somma-Vesuvius volcano, located near the city of Naples, threatens about 800,000 peoples producing one of the highest volcanic risk in the world. In the framework of the EC FP7 project "MEDiterranean SUpersite Volcanoes" a multidisciplinary investigation was performed in March 2014. This survey aimed (1) at locating the present-day hydrothermal system of Somma-Vesuvius and (2) at identifying the preferential paths and fluid flows inside the volcano.
 The prospecting methods used were Electrical Resistivity Tomography (ABEM SAS 4000) with 64 electrodes at 40 m spacing (in Wenner alpha configuration), self-potential (SP), temperature (30 cm depth) and CO2 concentration in the soil at 20 m spacing. All the measurements were performed along a 7 km long profile completed with roll-along (North- West to South-East). The depth of investigation for ERT reached about 500 m. This method revealed an electrical conductive body (20-100 ohm.m) centered beneath the summit of the Vesuvius cone. This conductive body was interpreted as the present-day hydrothermal system of the volcanic complex. Regarding the shape of this structure we noticed a deeply different shape respect to the one observed on both Stromboli and Vulcano volcanoes. Indeed, the Vesuvius hydrothermal system appears to act as a body which is constrained up to 200-250 m below the surface and, moreover, also emphasized by the W-like shape of the SP signal. From ERT and SP results a diameter of around 1.7 km at the maximum depth of investigation is estimated for the hydrothermal system of Somma-Vesuvius.
 In addition, four weak thermal anomalies (6-13°C) are identified on the summit area. They can be explained as preferential paths of up-flowing fluids. It follows that the largest structure seen on both temperature signal and ERT tomography is related to the crater rim of the 1906 eruption. Furthermore, on both lower sides of Vesuvius cone a conductive body (300-600 ohm.m) is identified within a resistive

    Full Text Available In this paper, we analyze local earthquakes which occurred at Somma-Vesuvius during two episodes of intense seismic swarms, in 1989 and 1995 respectively. For the selected earthquakes we have computed accurate hypocentral locations, focal mechanisms and spectral parameters. We have also studied the ground acceleration produced by the largest events of the sequences (ML 3.0, at various digital stations installed in the area during the periods of higher seismic activity. The main result is that seismicity during the two swarm episodes presents similar features in both locations and focal mechanisms. Strong site dependent effects are evidenced in the seismic radiation and strong amplifications in the frequency band 10-15 Hz are evident at stations located on the younger Vesuvius structure, with respect to one located on the ancient Somma structure. Furthermore, seismic stations show peak accelerations for the same events of more than one order of magnitude apart.

  9. Origin of accretionary lapilli from the Pompeii and Avellino deposits of Vesuvius

    Accretionary lapilli from the Pompeii and Avellino Plinian ash deposits of Vesuvius consist of centimeter-sized spheroids composed of glass, crystal, and lithic fragments of submillimeter size. The typical structure of the lapilli consists of a central massive core surrounded by concentric layers of fine ash with concentrations of larger clasts and vesicles and a thin outer layer of dust. Clasts within the lapilli larger than 125 ..mu..m are extremely rare. The median grain-size of the fine ash is about 50 ..mu..m and the size-distribution is well sorted. Most constituent particles of accretionary lapilli display blocky shapes characteristic of grains produced by phreatomagmatic hydroexplosions. We have used the scanning electron microscope (SEM) in conjunction with energy dispersive spectral analysis (EDS) to investigate the textural and chemical variation along traverses from the core to the rim of lapilli from Vesuvius.

    Lava medals constitute a unique example that links Vesuvian eruptions to history, politics and science. Medals coined in the Vesuvius lava date back to the period in which the state of the volcano was characterized by an open conduit, so that warm lava was still used. This state of activity lasted from 1631 to 1944, a period of time during which effusive or effusive-explosive eruptions frequently occurred, followed by very short periods of rest. The medals were realized thro...

  14. Tephra layers from Holocene lake sediments of the Sulmona Basin, central Italy: implications for volcanic activity in Peninsular Italy and tephrostratigraphy in the central Mediterranean area

    We present a new tephrostratigraphic record from the Holocene lake sediments of the Sulmona basin, central Italy. The Holocene succession is represented by whitish calcareous mud that is divided into two units, SUL2 (ca 32 m thick) and SUL1 (ca 8 m thick), for a total thickness of ca 40 m. These units correspond to the youngest two out of six sedimentary cycles recognised in the Sulmona basin that are related to the lake sedimentation since the Middle Pleistocene. Height concordant U series age determinations and additional chronological data constrain the whole Holocene succession to between ca 8000 and 1000 yrs BP. This includes a sedimentary hiatus that separates the SUL2 and SUL1 units, which is roughly dated between Somma-Vesuvius Holocene volcanic activity, and one to the Ischia Island eruption of the Cannavale tephra (2920 ± 450 cal yrs BP). The 27 ash layers compatible with Mt. Somma-Vesuvius activity are clustered in three different time intervals: from ca 2000 to >1000; from 3600 to 3100; and from 7600 to 4700 yrs BP. The first, youngest cluster, comprises six layers and correlates with the intense explosive activity of Mt. Somma-Vesuvius that occurred after the prominent AD 79 Pompeii eruption, but only the near-Plinian event of AD 472 has been tentatively recognised. The intermediate cluster (3600-3100 yrs BP) starts with tephra that chemically and chronologically matches the products from the "Pomici di Avellino" eruption (ca 3800 ± 200 yrs BP). This is followed by eight further layers, where the glasses exhibit chemical features that are similar in composition to the products from the so-called "Protohistoric" or AP eruptions; however, only the distal equivalents of three AP events (AP3, AP4 and AP6) are tentatively designated. Finally, the early cluster (7600-4700 yrs BP) comprises 12 layers that contain evidence of a surprising, previously unrecognised, activity of the Mt. Somma-Vesuvius volcano during its supposed period of quiescence, between

    In a recently published manuscript [Guidoboni, E., Boschi, E., 2006. Vesuvius before the 1631 eruption, EOS, 87(40), 417 and 423]; [Guidoboni, E. (Ed.), 2006. Pirro Ligorio, Libro di diversi terremoti (1571), volume 28, codex Ja II 15, Archivio di Stato di Torino, Edizione Nazionale delle Opere di Pirro Ligorio, Roma, De Luca, 261 pp], Pirro Ligorio gives a detailed description of the phenomena occurring in the crater area of Vesuvius volcano, in 1570-1571 and previous years. Here, these phenomena are interpreted as the first clearly documented signals of unrest of this volcanic system caused by the shallow emplacement of a magma batch and leading to the 1631 eruption. Our interpretation is mainly based on the present understanding of the fluid geochemistry of magmatic-hydrothermal systems. In this way, it is possible to conclude that: (i) incandescent rocks were present at the surface, with temperatures > 500 °C approximately and (ii) either a magmatic-dominated or a magmatic-hydrothermal-type of conceptual geochemical model applies to Vesuvius in 1570-1571 and preceding years. The Ligorio's picture represents the first clear evidence that the magma involved in the 1631 eruption was present under the volcano more than sixty years before the eruption. Moreover, its emplacement produced a series of phenomena which were clearly observed although not understood at that time. A similar phenomenological pattern should be easily detected and correctly interpreted at present or in the future.

    1998-01-01

    Between 1884 B.C. and A.D. 472, eruptive activity at Somma-Vesuvius was dominated by the three plinian eruptions of Avellino (3550 yr B.P.), Pompei (A.D. 79) and A.D. 472 and, as a result, little attention has been given to the intervening interplinian activity. The interplinian events are here reconstructed using new data from twenty stratigraphic sections around the lower flanks of the volcano. Three main eruptions have been identified fro the protohistoric period (3550 yr B.P.-A.D. 79). The first two occurred shortly after the Avellino event and both show a progression from magmatic to phreatomagmatic behaviour. The third eruption (2700 B.P.) consisted of five phreatomagmetic episodes separated by the emplacement of mud flows. Only one event, the explosive erupton of A.D. 203, has been identified for the ancient historic period (A.D. 79-472). In contrast, the A.D. 472 eruption was followed during the medievel period (A.D. 472-1631) by comparatively vigorous interplinian activity, including four strombolian-phreatomagmatic events and extensive lava effusion, which formed a summit cone (destroyed in A.D. 1631) similar to that on Vesuvius today. Such regular alternations of plinian and interplinian events are evident only since 3550 yr B.P. and provide important constraints for forecasting future behaviour at Somma-Vesuvius.

    Full Text Available Luigi Palmieri (Faicchio 1807 -Naples 1896, was appointed Director of the Vesuvius Observatory in 1855. He rea1ized the first model of electromagnetic seismograph and the uninterrupted use at the Observatory of this instrument represented the first step towards a geophysical sensu strictu surveillance of Mt. Vesuvius area. Already at the end of the 18th century, Ascanio Filomarino had built a mechanical seismograph which was ab1e to record the amplitude of the seismic waves, the incoming direction of the earthquake and its starting time. In 1862 Michele Baldacchini proposed to the Neapolitan scientific community a question about the possibility to use the study of precursory signs of the Vesuvian eruptions to inform in advance people living near the vo1cano. Palmieri answered Baldacchini's request, giving proof of extreme far-sightedness from the scientific point of view but, similarly, much concreteness from the practica1 point of view: he described, with modern ideas, the things to do in order to carry out the surveillance in the Mt. Vesuvius area, but concluded thus: "Till we have not the (economic and instrumental means we have spoken above, I think it is useless to entertain the Academy about the nature and the method of the observations and investigations to be performed".

    A 5 m thick pyroclastic and volcaniclastic sequence, never reported before, comprising a pumice fall deposit has been recognized in a disused quarry near Pollena Trocchia, on the NW slope of Somma-Vesuvius. It is composed of three stratigraphic units: a pumice fall deposit that underlies a pyroclastic density current deposit; they are overlain by a volcaniclastic unit emplaced during a quiescent period of the volcano. The pyroclastic deposits are separated by a horizon of reworked material indicating the emplacement from two distinct eruptive events. The pumice fall deposit has been subject of a detailed investigation. It consists of an ash bed overlaid by a roughly stratified pumice fall layer. The presence of ballistic clasts indicates the proximal nature of this deposit and its stratigraphic position below the Pomici di Base (22 ka) Plinian deposit allows constraining its age to the pre-caldera period (22-39 ky) of activity of Somma-Vesuvius. Samples have been collected in order to perform sedimentological (grain size and componentry), geochemical and isotopic analyses. Samples range from moderately to poorly sorted and show a trachytic composition. The comparison with literature data of compatible deposits vented from Somma-Vesuvius (Schiava, Taurano and Codola eruptions as well as borehole data) allows excluding any correlation with already known Vesuvian products suggesting that the analysed products are ascribable to a new, pre-caldera, explosive eruption. We name this new event ;Carcavone eruption;. Based on thickness, maximum lithic clasts and orientation of impact sags, showing a provenance from SE, we envisage the emplacement from a Plinian style eruption vented in the northern sector of the current caldera.

    During the past 22 ka of activity at Somma-Vesuvius, catastrophic pyroclastic density currents (PDCs) have been generated repeatedly. Examples are those that destroyed the towns of Pompeii and Ercolano in AD 79, as well as Torre del Greco and several circum-Vesuvian villages in AD 1631. Using new field data and data available from the literature, we delineate the area impacted by PDCs at Somma-Vesuvius to improve the related hazard assessment. We mainly focus on the dispersal, thickness, and extent of the PDC deposits generated during seven plinian and sub-plinian eruptions, namely, the Pomici di Base, Greenish Pumice, Pomici di Mercato, Pomici di Avellino, Pompeii Pumice, AD 472 Pollena, and AD 1631 eruptions. We present maps of the total thickness of the PDC deposits for each eruption. Five out of seven eruptions dispersed PDCs radially, sometimes showing a preferred direction controlled by the position of the vent and the paleotopography. Only the PDCs from AD 1631 eruption were influenced by the presence of the Mt Somma caldera wall which stopped their advance in a northerly direction. Most PDC deposits are located downslope of the pronounced break-in slope that marks the base of the Somma-Vesuvius cone. PDCs from the Pomici di Avellino and Pompeii Pumice eruptions have the most dispersed deposits (extending more than 20 km from the inferred vent). These deposits are relatively thin, normally graded, and stratified. In contrast, thick, massive, lithic-rich deposits are only dispersed within 7 to 8 km of the vent. Isopach maps and the deposit features reveal that PDC dispersal was strongly controlled by the intensity of the eruption (in terms of magma discharge rate), the position of the vent area with respect to the Mt Somma caldera wall, and the pre-existing topography. Facies characteristics of the PDC deposits appear to correlate with dispersal; the stratified facies are consistently dispersed more widely than the massive facies.

    The Vesuvius represents, undoubtedly, the icon of volcanic threats, since more than 600,000 people live very close to the volcano. This image is strengthened by the presence of the archaeological ruins of Pompeii and Herculaneum, buried by the 79 A.D. plinian eruption, testifying nowadays the highly destructive impact on humans, buildings and environments. Nevertheless, many young people live in the Vesuvian area show an inadequate preparedness to face the next eruption. This is inferred by the results of a multiple choice questionnaire, distributed to 400 high-school students in three municipalities located close to the volcano during the 2007. The questionnaire was aimed to understand the level of risk perception and preparedness of at-risk communities during the current quiescent period. The interviewed students show high levels of fear, poor perceived ability to protect themselves from the effects of a future eruption, and insufficient knowledge of the National Emergency Plan for Vesuvian Area (NEPVA). This result suggests that, during a future eruption of Vesuvius, there may not be enough time to educate the large number of people living near the volcano about how to appropriately respond. The lack of knowledge about NEPVA is a sign of the absence of well-tested communication strategies and effective information dissemination in the study area. This lack of knowledge also means there is little interest in participating in risk-reduction activities. The inadequate risk education and preparedness of respondents implies that a strong effort is needed to improve communication strategies in order to facilitate successful evacuations. Therefore, it is important to take advantage of the present period of quiescence at Vesuvius to increase the risk perception of youth in local communities. In the absence of adequate preparedness measures, an evacuation could become "enforced" or even worse, a "failure."

    Full Text Available The typical earthquakes occurring at Mt. Vesuvius are Volcano-Tectonic. On July 20, 2003, an unusual earthquake with low and narrow frequency content was detected. The seismograms presented an emergent onset and a nearly monochromatic spectrum at all stations of the Osservatorio Vesuviano (Istituto Nazionale di Geofisica e Vulcanologia seismic network. The event was located at about 4 km b.s.l. close to the crater axis and an equivalent duration magnitude of 0.6 was estimated. The nature of this event was investigated by comparing its features with those of two typical Volcano-Tectonic earthquakes occurred inside the same source volume. We compared the spectral content calculating the spectrograms and the coda patterns using the Hilbert Transform. A Seismic Moment Tensor inversion was performed on the low frequency earthquake. The focal mechanisms for the two Volcano-Tectonic earthquakes were estimated with a classical technique and resulted compatible with the stress field acting on the volcano. Taking into account the clear differences with the typical Volcano-Tectonic events as well as the peculiarities retrieved from our analyses (monochromatic, low frequency spectral content, and sustained coda and also some geochemical observations, we classify the unusual low frequency seismic event detected at Mt. Vesuvius as Long Period earthquake and propose that its origin could be linked to a pressure drop in the deep hydrothermal system.

    Through a 3D finite element code we simulate, the deformation of Somma-Vesuvius volcano caused by some overpressure sources. Under the assumption of linear elastic isotropic material behavior, the volcano deformation sources are located at various depths and their geometry (shape and lateral extension) is mainly constrained by the results of recent seismic tomography studies. These simulations have the objective to inquire about the influence of topography and structural heterogeneity on ground deformation. Structural heterogeneities have been modeled in terms of dynamical elastic parameters (Young's modulus) accounting for previous seismic tomography and gravity studies. Topography of Somma-Vesuvius is taken into account, using a digital terrain model. The main outcomes of this study is a strong deviation from axially symmetric pattern of the displacement field, which is quietly unaccounted by simplistic Mogi modeling in homogeneous medium with simplified topography. These results demonstrate that real topography and structural heterogeneities are key factors controlling the pattern of ground deformations, i.e. one of the most relevant problem in volcano monitoring. Moreover, an improved knowledge of deformation patterns can significantly help in the location of monitoring sensors as well as in the design of an efficient geodetic network.

The GPS data processing is performed by the Bernese software v. 5.0. The results of the data processing show that the dynamics of the Somma-Vesuvio volcano, between 2001 and 2012, is characterized by a general subsidence, with maximum values on the Gran Cono at BKNO (−11.7 ± 0.65 mm/year and BKE1 (−4.92 ± 0.36 mm/year stations. The subsidence decrease from the crater down to the coast and the horizontal displacements are concentrated in Gran Cono area, the youngest part of the volcano. The parameters of the principal strain components indicate that Somma-Vesuvius is affected by a predominant contraction phase, which is concentrated in the areas with the greatest altitudes.

    Full Text Available In this paper, we present a series of self-potential measurements at Somma-Vesuvius volcanic area acquired in conjunction with an active seismic tomography survey. The aim of our study is both to provide further confirmation to the occurrence of seismo-electric coupling and to identify sites suitable for self-potential signal monitoring at Somma-Vesuvius district. The data, which were collected along two perpendicular dipoles, show significant changes on the natural electric field pattern. These variations, attributable to electrokinetic processes triggered by the artificial seismic waves, were observed after explosions occurred at a distance less than 5 km from the SP dipole arrays. In particular, we found that the NW-SE component of the natural electric field was more sensible to the shots than the NE-SW one, and the major effects did not correspond to the nearest shots. Such evidences were interpreted considering the underground electrical properties as deduced by previous detailed resistivity and self-potential surveys performed in the study area.

    With the in-vessel vapor explosion issue ({alpha}-mode failure) now considered to pose an acceptably small risk to the safety of a light water reactor, ex-vessel vapor explosions are being given considerable attention. Attempts are being made to analytically model breakup of continuous-phase jets, however uncertainty exists regarding the basic phenomena. In addition, the conditions upon reactor vessel failure, which determine the starting point of the ex-vessel vapor explosion process, are difficult to quantify. Herein, molten jet ejection from the reactor pressure vessel is characterized. Next, the expected mode of jet breakup is determined and the current state of analytical modeling is reviewed. A jet breakup model for ex-vessel scenarios, with the primary breakup mechanism being the Kelvin-Helmholtz instability, is described. The model has been incorporated into the VESUVIUS module and comparisons of VESUVIUS calculations against FARO L-06 experimental data show differences, particularly in the pressure curve and amount of jet breakup. The need for additional development to resolve these differences is discussed. (author)

  7. Ash fallout scenarios at Vesuvius: Numerical simulations and implications for hazard assessment

    2008-12-01

    Volcanic ash fallout subsequent to a possible renewal of the Vesuvius activity represents a serious threat to the highly urbanized area around the volcano. In order to assess the relative hazard we consider three different possible scenarios such as those following Plinian, Sub-Plinian, and violent Strombolian eruptions. Reference eruptions for each scenario are similar to the 79 AD (Pompeii), the 1631 AD (or 472 AD) and the 1944 AD Vesuvius events, respectively. Fallout deposits for the first two scenarios are modeled using HAZMAP, a model based on a semi-analytical solution of the 2D advection-diffusion-sedimentation equation. In contrast, fallout following a violent Strombolian event is modeled by means of FALL3D, a numerical model based on the solution of the full 3D advection-diffusion-sedimentation equation which is valid also within the atmospheric boundary layer. Inputs for models are total erupted mass, eruption column height, bulk grain-size, bulk component distribution, and a statistical set of wind profiles obtained by the NCEP/NCAR re-analysis. We computed ground load probability maps for different ash loadings. In the case of a Sub-Plinian scenario, the most representative tephra loading maps in 16 cardinal directions were also calculated. The probability maps obtained for the different scenarios are aimed to give support to the risk mitigation strategies.

    Background The study of ancient skeletal pathologies can be adopted as a key tool in assessing and tracing several diseases from past to present times. Skeletal fluorosis, a chronic metabolic bone and joint disease causing excessive ossification and joint ankylosis, has been only rarely considered in differential diagnoses of palaeopathological lesions. Even today its early stages are misdiagnosed in endemic areas. Methodology/Principal Findings Endemic fluorosis induced by high concentrations of fluoride in water and soils is a major health problem in several countries, particularly in volcanic areas. Here we describe for the first time the features of endemic fluorosis in the Herculaneum victims of the 79 AD eruption, resulting from long-term exposure to high levels of environmental fluoride which still occur today. Conclusions/Significance Our observations on morphological, radiological, histological and chemical skeletal and dental features of this ancient population now suggest that in this area fluorosis was already endemic in Roman times. This evidence merged with currently available epidemiologic data reveal for the Vesuvius area population a permanent fluoride health hazard, whose public health and socio-economic impact is currently underestimated. The present guidelines for fluoridated tap water might be reconsidered accordingly, particularly around Mt Vesuvius and in other fluoride hazard areas with high natural fluoride levels.

    The possibility of intermediate-term earthquake prediction at Mt. Vesuvius by means of the algorithm CN is explored. CN was originally designed to identify the Times of Increased Probability (TIPs) for the occurrence of strong tectonic earthquakes, with magnitude M >= M sub 0 , within a region a priori delimited. Here the algorithm CN is applied, for the first time, to the analysis of volcanic seismicity. The earthquakes recorded at Mt. Vesuvius, during the period from February 1972 to October 2002, are considered and the magnitude threshold M sub 0 , selecting the events to be predicted, is varied within the range: 3.0 - 3.3. Satisfactory prediction results are obtained, by retrospective analysis, when a time scaling is introduced. In particular, when the length of the time windows is reduced by a factor 2.5 - 3, with respect to the standard version of CN algorithm, more than 90% of the events with M >= M sub 0 occur within the TIP intervals, with TIPs occupying about 30% of the total time considered. The co...

  11. 19 years of tilt data on Mt. Vesuvius: state of the art and future perspectives

    2013-11-01

    Full Text Available Mt. Vesuvius, located along the SW border of the Campania Plane graben, is one of the most studied volcanoes worldwide, from both the volcanological and the geophysical, geochemical and geodetic point of view. In order to better understand its dynamics, the deformation of the volcano has been already studied since the early ’70s by setting up levelling lines and, since a few years later, through trilateration networks, whereas ground tilt monitoring started in 1993. Tilt variations were recorded by an automatic surface station set up at the Osservatorio Vesuviano (O.V. bunker (OVO and data recorded were transmitted to the O.V. Surveillance Centre in Naples. Afterwards, in 1996 two more identical stations were set up close to Torre del Greco (CMD, and close to Trecase (TRC. In 2002 the data acquisition system was replaced, while at the end of 2011 a Lily borehole sensor was set up at 26 m depth, replacing the old TRC tilt station. The paper describes in details the tilt network of Mt. Vesuvius, its development over time and the data processing procedure; moreover, the ground deformation pattern is discussed, as inferred from the study of 19 years of data and its change during the seismic crises of 1995-1996 and 1999-2000. From the information obtained from the tiltmetric monitoring, a complex deformation pattern can be deduced, strongly dependent on the position of the sites in which the sensors were set up with respect to the morphology of the volcanic edifice and its structural outlines. If we consider the signals as they were recorded, although previously corrected for the influences of the thermo-elastic strain on the sensors, the tilting occurs mainly in the SW direction with rates of about 11 µradians/year on both the western and eastern flanks and of about 13 µradians/year on the southern one. Because tilt vectors point in the long term outward from the summit and towards the subsiding area, this supports the hypothesis of a southern

    There is a growing number of evidences in the surrounding plain of Somma-Vesuvius volcano which indicate that along with primary volcanic processes (i.e. fallout, pyroclastic density currents) the syn-eruptive and post-eruptive volcaniclastic remobilization has severely impacted the ancient civilizations, which flourished in the area. This represents an important starting point for understanding the future hazard related to a potential (and not remote) renewal of volcanic activity of the Campaniana volcanoes. We present geoarcheological and stratigraphic data obtained from the analysis of more than 160 sections in the Campanian plain showing the widespread impact of volcaniclastic debris flows and floods originated from the rapid remobilization of the products of the AD 472 eruption of Somma-Vesuvius, both on the environment and on the human landscape. This eruption was one of the two sub-Plinian historical events of Somma Vesuvius. This event largely impacted the northern and eastern territory surrounding the volcano with deposition of a complex sequence of pyroclastic-fallout and -current deposits. These sequences were variably affected by syn- and post-eruptive mobilization both along the Somma-Vesuvius slopes and the Apennine valleys with the emplacement of thick mud- and debris-flows which strongly modified the preexisting paleogeography of the Plain with irretrievable damages to the agricultural and urban landscape. The multidisciplinary approach to the study of the sequences permitted to reconstruct the palaeoenvironment before the eruption and the timing of the emplacement of both pyroclastic and volcanoclastic deposits. The preexisting landscape was characterized by intense human occupation, although showing strong evidences of degradation and abandonment due to the progressive decline of the Roman Empire. The impact of volcaniclastic flows continued for decades after the eruption as highlighted in the studied sequences by stratigraphic and archaeologic

    Full Text Available The Campanian volcanism develops near the sea. Therefore, the geophysical study of the marine environment is a key to a better understanding of the tectonic evolution and the origin of volcanism in the area. An abundance of high quality seismic data in the marine sector, where little direct information is available, is critical to the study of Campanian volcanism. This paper concerns the reprocessing of a seismic reflection dataset acquired in Naples Bay and processed during 1973. Even though the overall data quality was high for that time, of course their acquisition technological limits have been overcome by the new processing. Our reprocessing aimed at: 1 reduction of random noise in the data; 2 removal of unwanted coherent events; 3 reduction of spatial aliasing by means of trace interpolation on Commod Shot Point (CSP gathering; 4 improvement of resolution of the seismic wavelet with spiking deconvolution algorithms and finally 5 reposition of reflectors in their correct locations in the space-TWT domain by means of dip moveout and post-stack time migration. A comparison between the new and old data shows that the new sections are characterized by a much higher S/N ratio. Diffraction hyperbole has been collapsed. Reverberations, ghosts and multiples have been removed or greatly attenuated, especially between the reflectors of interest, allowing us to follow them with more detail and with greater continuity. Furthermore, data resolution has been boosted by the reprocessing, allowing the interpreter to evaluate reflector position and continuity in greater detail. The reinterpretation phase of such lines, that is already in an advanced stage, will therefore allow us to gain new insights into the structural setting of the bay, with the aim of exploring the connection between tectonics and volcanism.

    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.

    Mt. Somma-Vesuvius Plinian eruptions were first described by Pliny the younger in 79 AD during the infamous eruption that destroyed Pompeii. Today, such eruptions are still a concern to the nearly 3 million people living in the Naples metropolitan area. Understanding the source for Mt. Somma-Vesuvius magma and the coexisting volatile phase is vital to better constrain the long-term eruptive behavior of this volcano. In the present study, ~ 50 olivine phenocrysts were selected from lavas and pumices produced during mild effusive events referred to as inter-Plinian eruptions, and from highly explosive Plinian eruptions that occurred at Mt. Somma-Vesuvius between 33000 ka and 1631 AD. Selected olivine phenocrysts containing MI were examined petrographically and analyzed for Fo content. Fo varies from 69 to 73 mole% for inter-Plinian olivine crystals and from 84 to 90 mole% with one zoned olivine containing 76-81 mole% Fo, for Plinian olivine crystals. Investigated MI vary from slightly crystallized to highly crystallized. Selected crystallized MI were reheated using the Vernadsky stage, and quenched to a homogeneous glass (Group 1) or glass plus a vapor bubble (Group 2). On one hand, MI of Group 1 are hosted in olivine ranging from Fo72 to Fo76 and were all erupted from the Pompeii eruption (white pumice deposit). On the other hand, MI of Group 2 are trapped in olivine ranging from Fo69 to Fo81 and from Fo84 to Fo90, and the hosts are representative of both Plinian and inter-Plinian events. The only eruption where Group-1 and Group-2 MI coexist is the Pompeii eruption. Group 2 MIs were further analyzed by Raman to test for the presence of volatiles (CO2 or H2O) in the vapor bubbles. CO2 was detected in all MI analyzed. CO2 density was determined using the distance between the two Fermi-diad peaks, and ranges between 0.14 and 0.55 g/cm3. Six MI also showed evidence for H2O in the vapor bubble. In addition, carbonates were detected at the glass-vapor interface of five

    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.

  17. Volcanic hazard at Vesuvius: An analysis for the revision of the current emergency plan

    Mt Somma-Vesuvius is a composite volcano on the southern margin of the Campanian Plain which has been active since 39 ka BP and which poses a hazard and risk for the people living around its base. The volcano last erupted in 1944, and since this date has been in repose. As the level of volcanic risk perception is very high in the scientific community, in 1995 a hazard and risk evaluation, and evacuation plan, was published by the Italian Department of Civil Protection ( Dipartimento della Protezione Civile) . The plan considered the response to a worst-case scenario, taken to be a subplinian eruption on the scale of the 1631 AD eruption, and based on a volcanological reconstruction of this eruption, assumes that a future eruption will be preceded by about two weeks of ground uplift at the volcano's summit, and about one week of locally perceptible seismic activity. Moreover, by analogy with the 1631 events, the plan assumes that ash fall and pyroclastic flow should be recognized as the primary volcanic hazard. To design the response to this subplinian eruption, the emergency plan divided the Somma-Vesuvius region into three hazard zones affected by pyroclastic flows (Red Zone), tephra fall (Yellow and Green Zone), and floods (Blue Zone). The plan at present is the subject of much controversy, and, in our opinion, several assumptions need to be modified according to the following arguments: a) For the precursory unrest problem, recent scientific studies show that at present neither forecast capability is realistic, so that the assumption that a future eruption will be preceded by about two weeks of forecasts need to be modified; b) Regarding the exposure of the Vesuvius region to flow phenomena, the Red Zone presents much inconsistency near the outer border as it has been defined by the administrative limits of the eighteen municipality area lying on the volcano. As this outer limit shows no uniformity, a pressing need exists to define appropriately the flow hazard

    One of the current stakes in modern volcanology is the definition of magma storage conditions which has direct implications on the eruptive style and thus on the associated risks and the management of likely related crisis. In alkaline differentiated magmas, chlorine (Cl), contrary to H2O, occurs as a minor volatile species but may be used as a geobarometer. Numerous experimental studies on Cl solubility have highlighted its saturation conditions in alkaline silicate melts. The NaCl-H2O system is characterized by immiscibility under wide ranges of pressure, temperature and NaCl content (Somma-Vesuvius: We have analysed the products of 13 explosive eruptions of Monte Somma-Vesuvius, including four Plinian (Pomici di Base, Mercato, Avellino, Pompeii), five sub-Plinian (Verdoline, AP1, AP2, Pollena, 1631 AD) and four violent strombolian to ash emission events (AP3, 1822, 1906, 1944). We have focussed our research on the earliest emitted, most evolved products of each eruption, likely representing the shallower, H2O-saturated portion of the reservoir. We highlighted two magma ponding zones, at ~170-200 MPa and ~105-115 MPa. We have also estimated maximum pre-eruptive H2O content for the different magma compositions, varying between 3.5 and 7 wt%. The results, in large agreement with literature, are very promising. The Cl geobarometer may help scientists to define the reservoir dynamics through time and provide strong constraints on pre-eruptive conditions, of outmost importance for the interpretation of the monitoring data and the identification of precursory signals.

    Vesuvius is a high-risk volcano and the 1631 Plinian eruption is a reference event for the next episode of explosive unrest. A complete stratigraphic and petrographic description of 1631 pyroclastics is given in this study. During the 1631 eruption a phonolite was firstly erupted followed by a tephritic phonolite and finally a phonolitic tephrite, indicating a layered magma chamber. We suggest that phonolitic basanite is a good candidate to be the primitive parental-melt of the 1631 eruption. Composition of apatite from the 1631 pyroclastics is different from those of CO2-rich melts indicating negligible CO2 content during magma evolution. Cross checking calculations, using PETROGRAPH and PELE software, accounts for multistage evolution up to phonolite starting from a phonolitic basanite melt similar to the Vesuvius medieval lavas. The model implies crystal settling of clinopyroxene and olivine at 6 kbar and 1220°C, clinopyroxene plus leucite at a pressure ranging from 2.5 to 0.5 kbar and temperature ranging from 1140 to 940°C. Inside the phonolitic magma chamber K-feldspar and leucite would coexist at a temperature ranging from from 940 to 840°C and at a pressure ranging from 2.5 to0.5 kbar. Thus crystal fractionation is certainly a necessary and probably a sufficient condition to evolve the melt from phono tephritic to phonolitic in the 1631 magma chamber. We speculate that phonolitic tephrite magma refilling from deeper levels destabilised the chamber and triggered the eruption, as testified by the seismic precursor phenomena before 1631 unrest.

    Full Text Available The history of Vesuvius and its central cone or Great Cone (Gran Cono is important because it enables us to improve our understanding of the structural evolution of Somma-Vesuvius. Apart from geological and stratigraphic studies, investigations of the literary and artistic testimonies can also help to clarify some unresolved problems. Recently a detailed study of the consequences of the 1631 eruption on the volcano morphology as well as that of the following volcanic activity has shown that the present central cone was formed in the last few centuries after that eruption. With regard to the history of the central cone prior to the 1631 eruption, rare writings and iconographic records help clarify this question. In this short communication we announce the discovery of a new image representing Vesuvius before the 79 A.D. eruption identified in a fresco from Pompei excavations. This fresco could confirm the interpretation of a well-known Strabo quotation according to which there already existed a large caldera prior to the 79 A.D. eruption.

    Full Text Available The volcanologic literature concerning Vesuvius and its activity, since the great eruption of 1631, is particularly abundant and helpful in order to investigate topics of remarkable interest on the eruptive history of the Neapolitan volcano. One of these topics relates to the precursory phenomena of the eruption of 1631. This problem it is of great importance for a better knowledge of the eruptive trends of the volcano since the 1631 eruption is the reference for any Civil Defence plan regarding the Vesuvius volcano. In addition, knowledge of the medieval activity of Vesuvius is important because it furnishes useful data for research into some unfamiliar aspects of the volcano's history, e.g., the existence of a 1500 eruption and consequently the duration of the inactivity period before 1631. It is generally assumed that the precursors of this eruption occurred less than one month before its beginning. In particular, the earthquakes would have come about 10 days before the eruption. Moreover a soil uplift is reported about 20 days beforehand. On the basis of a careful analysis of some important sources, books and manuscripts, we will see that the outline of the phenomena was much more complex.

    Somma-Vesuvius is considered one of the highest-risk volcanic systems in the world due to its high population density and record of highly destructive explosive activity. Eruptive style at Vesuvius varies greatly, alternating between effusive and explosive activities, and is likely strongly controlled by the evolution of the physical and chemical properties of the magma. Nevertheless, with the exception of the 1631 eruption, the rheological properties of Vesuvius magmas remain largely unconstrained. Here, we investigate the Newtonian shear viscosity ( η) of dry and hydrous melts from the Mercato (plinian) and 1906 (violent strombolian) eruptions. These eruptions differ in size, eruptive style and magma chemistry (from phonolite to phono-tephrite). To evaluate the dry liquid viscosity variation covered by the eruptive products of the recent activity at Vesuvius, we measured the melt viscosities of bulk rock compositions and, for highly crystalline samples, of the separated groundmasses of tephras from the Pollena and 1906 eruptions. Hydrated samples with up to 4.24 wt% dissolved water were synthesised in a piston cylinder apparatus at confining pressure up to 10 kbar. The dry high temperature and the dry and hydrous low-temperature viscosities were obtained by combining the concentric cylinder and micropenetration techniques. The measured viscosities were parameterized by a modified Vogel-Fulcher-Tammann equation, accounting for the effect of water content, and were compared with previous measurements and models. At magmatic temperatures, the viscosities of Mercato samples are about four orders of magnitude higher than that of the least viscous investigated products from the 1906 eruption. Complex numerical models to forecast eruptive scenarios and their environmental impact are extremely sensitive to the accuracy of the input parameters and constitutive equations of magma properties. As a consequence, the numerical expressions obtained here are of particular

    Full Text Available Infrared remote sensing monitoring is a significant tool aimed to integrated surveillance system of active volcanic areas. In this paper we describe the realization and the technological evolution of the permanent image thermal infrared (TIR surveillance system of the Vesuvius volcano. The TIR monitoring station was installed on the Vesuvius crater rim on July 2004 in order to acquire scenes of the SW inner slope of Vesuvius crater that is characterized by a significant thermal emission. At that time, it represented the first achievement all over the world of a permanent surveillance thermal imaging system on a volcano. It has been working in its prototypal configuration till May 2007. The experience gained over years about the engineering, management and maintenance of TIR remote acquisition systems in extreme environmental conditions, allows us to design and realize a new release of the TIR monitoring station with improved functionalities and more flexibility for the IR image acquisition, management and storage, which became operational in June 2011. In order to characterize the thermal background of the Vesuvius crater at present state of volcanic quiescence, the time series of TIR images gathered between July 2004 and May 2012 were analyzed using a statistical approach. Results show no significant changes in the thermal radiation during the observation periods, so they can be assumed as representative of a background level to which refer for the interpretation of possible future anomalies related to a renewal of the volcanic dynamics of the Vesuvius volcano.

    Geological processes are generally very complex and too slow to be directly observed in their completeness; modelling procedures overcome this limit. The state of stress in the upper lithosphere is the main responsible for driving geodynamical processes; in order to retrieve the active stress field in a rock volume, stress inversion techniques can be applied on both seismological and structural datasets. This approach has been successfully applied to active tectonics as well as volcanic areas. In this context the best approach in managing heterogeneous datasets in volcanic environments consists in the analysis of spatial variations of the stress field by applying robust techniques of inversion. The study of volcanic seismicity is an efficient tool to retrieve spatial and temporal pattern of the pre-, syn- and inter-eruptive stress field: magma migration as well as dynamics of magma chamber and hydrothermal system are directly connected to the volcanic seismicity. Additionally, analysis of the temporal variations of stress field pattern in volcanoes could be a useful monitoring tool. Recently the stress field acting on several active volcanoes has been investigated by using stress inversion techniques on seismological datasets (Massa et al., 2016). The Bayesian Right Trihedra Method (BRTM; D'Auria and Massa, 2015) is able to successfully manage heterogeneous datasets allowing the identification of regional fields locally overcame by the stress field due to volcano specific dynamics. In particular, the analysis of seismicity and stress field inversion at the Somma-Vesuvius highlighted the presence of two superposed volumes characterized by different behaviour and stress field pattern: a top volume dominated by an extensional stress field, in accordance with a gravitational spreading-style of deformation, and a bottom volume related to a regional extensional stress field. In addition, in order to evaluate the dynamics of deformation, both analogue and numerical

    The work reports the preliminary results of ten magnetotelluric (MT) soundings recorded in single-site mode above the Mt. Somma-Vesuvius volcanic area in 1997. The quality of data decreases going further from the caldera and approaching the sources of electromagnetic incoherent noise such as villages, antennas and repeaters. After a very accurate data analysis, the apparent resistivity and phase curves were interpreted with a 1D modelling instead a 2D one as it seems a more appropriate interpretative approach looking at the morphology of the curves and taking into account the 3 D geological conditions of the area. The results show an extended conductive structure at a depth of 0.3-1.2 km. It could be connected with a change in the physico-chemical characteristics of the volcano-sedimentary define the response MT curves for sites above this particular volcanic structure. This approach seems to be very interesting in view of specific interpretative targets, such as dimension and position of the magma chamber, when planning future MT surveys.

    Parasitic and eccentric cones on the flanks and at the base of Somma-Vesuvius potentially provide information on the plumbing system of the complex. We present geochemical data for minerals, glasses and rocks from the Pollena and Cercola cones. The rocks are phonotephrites and a basaltic trachyandesite. A volumetrically dominant type contains phenocrysts of olivine, clinopyroxene, leucite, plagioclase ± apatite ± Fe-Ti-oxides. A second type is phlogopite-phyric. Low magnesium-numbers (62-49) and Ni abundances (≤32 ppm) indicate that the primary magmas underwent crustal-level fractionation but the cores of olivine and clinopyroxene phenocrysts carry records of the parental magmas. Geochemical data indicate that the rocks form more than one magmatic lineage. Matrix glasses point to low-pressure fractionation trends towards decreasing melt silica-undersaturation. The phlogopite-phyric rocks were derived from more hydrous magmas than those lacking phlogopite phenocrysts, perhaps at higher pressures. Phenocryst assemblages are difficult to reconcile with published experimental work and it is likely that they are far from equilibrium assemblages. The cone magmas were probably derived from high levels within the main plumbing system via lateral transport.

    Detailed stratigraphic and micropalaeontological analyses of samples from boreholes at the Somma-Vesuvius apron, between Pompeii and the sea, allowed reconstruction of Late Quaternary palaeoenvironmental evolution of the Sarno coastal plain. In all, 116 samples were recovered from seven boreholes drilled from 2-10 m a.s.l. to 16.5-26 m b.s.l. Microfossil assemblages, with special regard to benthic foraminifers and ostracods, were used to reconstruct the depositional palaeoenvironment. Fossil remains show that all the pre-79 AD fossiliferous sediments from 2 to - 24 m a.s.l. were deposited in shallow marine waters for a long time despite an appreciable sea level rise. The data indicate alternation of both shallow marine and subaerial conditions during the last ~ 15 kyr, evidencing ground uplift of the area of about 75 m at a rate of ~ 5 mm/year. Marine sediment accumulation (~ 6 m/kyr) and tectonic uplift long offset the sea level rise, and as a consequence, submerged areas remained the same as well.

    Abrupt transitions in style and intensity are common during volcanic eruptions, with an immediate impact on the surrounding territory and its population. Defining the factors trigger such sudden shifts in the eruptive behavior as well as developing methods to predict such changes during volcanic crises are crucial goals in volcanology. In our research, the combined investigation of both petrological and seismic indicators has been applied for the first time to a Vesuvius eruption, that of March 1944 that caused the present dormant state of the volcano. Our results contribute to elucidate the evolution of the conduit dynamics that generated a drastic increase in the Volcanic Explosivity Index, associated to the ejection of huge amount of volcanic ash. Remarkably, our study shows that the main paroxysm was announced by robust changes in petrology consistent with seismology, thus suggesting that the development of monitoring methods to assess the nature of ejected juvenile material combined with conventional geophysical techniques can represent a powerful tool for forecasting the evolution of an eruption towards violent behavior. This in turn is a major goal in volcanology because this evidence can help decision-makers to implement an efficient safety strategy during the emergency (scale and pace of evacuation).

    Full Text Available The computing techniques currently available for the seismic monitoring allow advanced analysis. However, the correct event classification remains a critical aspect for the reliability of real time automatic analysis. Among the existing methods, neural networks may be considered efficient tools for detection and discrimination, and may be integrated into intelligent systems for the automatic classification of seismic events. In this work we apply an unsupervised technique for analysis and classification of seismic signals recorded in the Mt. Vesuvius area in order to improve the automatic event detection. The examined dataset contains about 1500 records divided into four typologies of events: earthquakes, landslides, artificial explosions, and “other” (any other signals not included in the previous classes. First, the Linear Predictive Coding (LPC and a waveform parametrization have been applied to achieve a significant and compact data encoding. Then, the clustering is obtained using a Self-Organizing Map (SOM neural network which does not require an a-priori classification of the seismic signals, groups those with similar structures, providing a simple framework for understanding the relationships between them. The resulting SOM map is separated into different areas, each one containing the events of a defined type. This means that the SOM discriminates well the four classes of seismic signals. Moreover, the system will classify a new input pattern depending on its position on the SOM map. The proposed approach can be an efficient instrument for the real time automatic analysis of seismic data, especially in the case of possible volcanic unrest.

  12. Short residence times for alkaline Vesuvius magmas in a multi-depth supply system: Evidence from geochemical and textural studies

    2010-07-01

    It is crucial to understand magma chamber chemico-physical conditions and residence times for high-risk volcanoes because these factors control the occurrence and size of future eruptions. In order to define magmatic pressure-temperature conditions and residence times at the Somma-Vesuvius volcano, we studied the geochemistry and texture of selected past eruptions that are representative of the entire volcanic history. Our petrological model indicates a multi-depth magma chamber composed of a deeper tephritic (350-400 Mpa) magma layer, which fed Strombolian and effusive eruptions during open-conduit activity, and an upper (200-250 Mpa) phonolitic level, which supplied the high explosive events that followed closed-conduit repose time. This upper reservoir matches the inferred transition between sedimentary sequences and metamorphic basement. At this level, the presence of a structural and lithological discontinuity favors magma storage during closed-conduit periods. The prevalent differentiation process was fractional crystallization during the magma cooling associated with upward migration of less dense, evolved liquids. Our results indicate that major steam exolution occurred during the late crystallization stage of phonolites, which accounts for the high Volcanic Explosivity Index (VEI) of eruptions supplied by these melts. Moreover, our phenocryst CSD data reveal the rapid crystallization and differentiation (decades to centuries) of alkaline Somma-Vesuvius magmas. This implies that the 400 km 2 partial melting zone detected by tomography studies at 8-10 km depth beneath Vesuvius should consist of differentiated magma that is already capable of generating a large-scale (plinian) explosive event if renewed activity develops out of the present closed-conduit state. Additionally, because our microlite CSD data indicate rapid magma migration from the chamber toward the surface, precursory activity could appear only short time before a major eruption.

    Full Text Available This paper presents a preliminary susceptibility map of the flood hazard for the Somma-Vesuvius volcanic district, worked out by means of multi-disciplinary historical, geological, geomorphological and rainfall data processing. It is well known that the Somma-Vesuvius volcano, due to its explosive volcanism and the dense urbanization of the surrounding area, with a population exceeding 650,000 is one of the most dangerous active volcanoes of the world. Although this area has been extensively studied from the volcanological point of view with regards to its volcanic hazard, there are currently not many detailed studies about its flood hazard factors, despite the fact that, in the last century, many intense rainfall events in this area have produced several floods that invaded the surrounding plains affecting towns and roads, and causing much damages and loss of lives. Accordingly, in this paper high-resolution DEM (5×5 m pixel and detailed geomorphological maps of the whole area have been analyzed and processed in GIS environment, carrying out a comparative study of the present-day morphology and the morphology of the 1900’s volcanic edifice, including changes of infrastructures and buildings throughout the last century. These results, together with historical chronicles data and the rainfall accurate data for all flood events, have been processed in this paper for highlighting the drainage basins areas of Somma-Vesuvius where the flood phenomena could be more probable in the future, working out a preliminary zoning map, also suggesting in which sectors interventions useful for mitigation of flood risk should be implemented.

    Full Text Available During 1997 ten magnetotelluric (MT soundings were recorded in single-site mode above the Mt. Somma-Vesuvius volcanic area. A first campaign of MT measurements was carried out, during spring, by the researchers of the University of Padua with their MSPM acquisition system. During autumn, the researchers of the International Institute of Geothermal Research (CNR Pisa with their Phoenix equipment performed a second campaign. A teach site, the horizontal components of the electrical and magnetic fields were recorded in the frequency band between 300-0.003 Hz. The MSPM system could record signals up to the frequency of 800 Hz. Data were recorded at one common site with both the different equipments to verify the compatibility of the two different acquisition systems. The soundings over the area of the volcano's caldera show a continuous morphology of the apparent resistivity and phase curves with small error bars: it means a good correlation between the orthogonal electrical and magnetic fields. The quality of data decreases going further from the caldera and approaching the sources of electromagnetic incoherent noise such as villages, antennas and repeaters. After a very accurate data analysis, the apparent resistivity and phase curves were interpreted with a 1D modelling instead a 2D one as it seems a more appropriate interpretative approach looking at the morphology of the curves and taking into account the 3D geological conditions of the area. The results show an extended conductive structure at a depth of 0.3-1.2 km. It could be connected with a change in the physico-chemical characteristics of the volcano-sedimentary cover (alteration paragenesis and possible hydrothermalism. A 3D MT forward modelling was then used to define the response MT curves for sites above this particular volcanic structure. This approach seems to be very interesting in view of specific interpretative targets, such as dimension and position of the magma chamber, when

    Full Text Available At present, the vesuvianite group of minerals consists of eight members, six of which are distinguished by the dominant cation in the Y1(A,B five-coordinated site. We investigated two vesuvianite samples from the type locality by electron microprobe analysis, Mössbauer and infrared spectroscopy, TGA/DSC, MAS NMR, single-crystal and powder X-ray diffraction. The crystal structures of these samples (# 27844 and 51062 from the Vesuvius collection, Fersman Mineralogical Museum, Moscow have been refined to R1 = 0.027 and R1 = 0.035, respectively. Both samples have the space group P4/nnc; a = 15.5720(3 and 15.5459(3, c = 11.8158(5 and 11.7988(4, respectively. In both samples low-occupied T1 and T2 sites are populated by minor B and Al, which agrees with their high-temperature origin. According to our experimental results, the general revised crystal-chemical formula of vesuvianite can be written as VII−IXX19VY1VIY12(Z2O74(ZO410(W10, where X are seven- to nine-coordinated sites of Ca with minor Na, K, Fe2+ and REE impurities; VY has a square pyramidal coordination and is occupied predominantly by Fe3+ with subordinate Mg, Al, Fe2+ and Cu2+; VIY has octahedral coordination and is predominantly occupied by Al with subordinate Mg, Fe2+, Fe3+, Mn2+, Mn3+, Ti, Cr and Zn; ZO4 = SiO4, sometimes with subordinate AlO4 and/or (OH4, and W = OH, F, with minor O and Cl. The idealized charge-balanced formula of the vesuvianite end-member without subordinate cations is Ca19Fe3+(Al10Me2+2(Si2O74(SiO410O(OH9, where Ме = Fe2+, Mg2+, Mn2+.

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

    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.

    Full Text Available A multidisciplinary project for the investigation of Mt. Vesuvius Structure was started in 1993. The core of the project is represented by a high resolution seismic tomography study by using controlled and natura1 sources. The main research objective is to investigate the feeding system of the vo1cano and to retrieve details of the upper crustal structure in the area. A first 2D using seismic experiment was performed in May 1994, with the aim of studing the feasibility of lIsing tomographic techniques for exploring the vo1cano interiors. Particularly, this experiment was designed to obtain information on the optimal sources-receivers configuration and on the depth extension of the volume sampled by shot-generated seismic waves. 66 three-component seismic stations and 16 single-component analogue instruments were installed by several Italian and French groups to record signals generated by three on-land, underground explosions. Sources and geophones were deployed along a 30-km NW-SE profile passing through the volcano crater. Receivers were placed at an average spacing of 250 m in the middle of the recording line and at 500 m outside. The arrival time data base was complemented by first P and S readings of micro earthquakes which occurred in the recent past within the volcano. The first arrival data set was preliminary used to determine the shallow structure of the volcano by applying Thurber's (1983 tomographic inversion technique. This analysis shows evidence for a high-velocity body which extends vertically from about 400 m below the crater down to at least 3000 m and for a shallow 300-500 m thick low-velocity cover which borders the edifice. Data from the distant shot show evidence for arrivals of deep reflected/converted phases and provide information on the deeper structure under the volcano. The results from the interpretation of 2D data are used for planning a 3D tomographic survey which will be cauied out in 1996.

    The 472 AD Pollena sub-Plinian eruption of Vesuvius was characterized by three main eruptive phases. Pulsatory eruptive dynamics were driven by magmatic fragmentation of a phonolitic (L1) to tephri-phonolitic magma (L8) during Phases I and II, whereas phreatomagmatic fragmentation dominated Phase III. In order to investigate magma dynamics, we integrated field data on the physical properties (column height, mass discharge rate) with a detailed chemico-textural analysis of the fall-out products (L1-L8), and with laboratory measurements of the phonolite (L1) and tephriphonolite (L8) multiphase rheology. The fall deposits mainly consist of crystal-bearing pumice (L1) or scoria (L2 to L8) lapilli. Gaussian Vesicle Volume Distributions (VVDs) indicate a single and rapid event of bubble nucleation and growth (Vesicle Number Density, VND = 107-109 cm-3). Cristallinity is constituted by dominant leucite and clinopyroxene and increases with stratigraphic height. The amount of H2O initially dissolved in the magma (1.7-3.6 wt% by Raman spectroscopy on Cpx-hosted melt inclusions) decreases from L1 to L8 layer. Anhydrous melt viscosity of the two end-member compositions was measured at high T (1000° C < T < 1500 ° C) and low T (680 ° C < T < 760 ° C) by concentric cylinder and micropenetration viscometry. Despite their chemical difference the non-Arrhenian behaviour of the viscosity-temperature curves yields very similar values at the inferred eruptive temperature (T =850° C). Liquid+crystals rheology of tephriphonolites (L8) was determined by isothermal (T= 1150 - 1190 ° C) crystallization experiments in a concentric cylinder set-up. The measured effect of crystals is in good agreement with literature models and the results can be extended to estimate natural magma rheology. During the first part of the eruption (L1 - L3), despite a decrease in H2O, the column height increases from 12 to 17 km, possibly related to a change of conduit/vent geometry. The following phases

    The 79AD eruption of Vesuvius, also known as the "Pompeii eruption", is the reference for one of the explosive eruptive styles, the plinian-type eruption. The eruption involved H2O-rich phonolitic magmas and is commonly divided into three phases: an initial phreatomagmatic phase, followed by a plinian event which produced a thick pumice fallout deposit and a final phase that was dominated by numerous column-collapse events. During the plinian phase, a first white pumice fallout was produced from a high steady eruptive column, followed by a grey pumice fallout originated by an oscillatory eruptive column with several partial column collapse events. This study focuses on the pumice fallout deposits, sampled in a proximal thick section, at the Terzigno quarry, 6 km southeast of the present crater. In order to constrain the degassing processes and the eruptive dynamics, major element compositions, residual volatile contents (H2O, Cl) and textural characteristics (vesicularity and microcrystallinity) were studied. A previous study that we performed on the pre-eruptive Cl content has shown that Cl may be used as an indicator of magma saturation with Cl-rich fluids and of pre-eruptive pressures. Cl contents measured in melt inclusions show that only the white pumice and the upper part of the grey pumice magma were H2O saturated prior eruption. Large variations in residual volatile contents exist between the different eruptive units and textural features strongly differ between white and grey pumice clasts but also within the grey pumice clasts. The degassing processes were thus highly heterogeneous: the white pumice eruptive units represent a typical closed-system degassing evolution whereas the first grey pumice one, stored in the same pre-eruptive saturation conditions, follows a particular open-system degassing evolution. Here we propose a new model of the 79AD eruption where pre-eruptive conditions (H2O saturation, magma temperature and viscosity) are the critical

    A study of six tephra layers discovered in different deposits between 1600 and 2700 m a.s.l. in the Apennine chain in central Italy allowed precise stratigraphic constraints on environmental and climatic changes between ca. 4.5 and 3.8 cal ka BP. Chemical analyses allowed the correlation of these tephra layers with the eruptions of Agnano Mt Spina (AMST) from Phlegrean Field and Avellino (AVT) from Somma-Vesuvius. Major environmental changes in the high mountains of the Central Apennines occurred just after the deposition of the AMST and predate the deposition of the AVT. At this time, renewed growth of the Calderone Glacier occurred, marking the onset of the Apennine "Neoglacial". The presence of the AMST and AVT enabled us to make a precise, physical correlation with other archives in central Italy. Synchronization of records between sites showed that the period intervening the deposition of the AMST and AVT layers coincided with environmental changes that were not always exactly in phase. This highlights the fact that stratigraphic correlations using only radiocarbon chronologies (the most common method used for dating archives during the Holocene) could produce erroneous correlation of events, giving rise to oversimplified paleoclimatic reconstructions.

  4. Understanding Vesuvius magmatic processes: Evidence from primitive silicate-melt inclusions in medieval scoria clinopyroxenes (Terzigno formation)

    Microthermometric investigations of silicate-melt inclusions and electron microprobe analyses were conducted on experimentally homogenized silicate-melt inclusions and on the host clinopyroxenes from 4 scoria samples of different layers from the Mt. Somma-Vesuvius medieval eruption (Formazione di Terzigno, 893 A.D.). The temperature of homogenization, considered the minimum trapping temperature, ranges from 1190 to 1260??5 ??C for all clinopyroxene-hosted silicate melt inclusions. The major and minor-element compositional trends shown by Terzigno scoria and matrix glass chemical analysis are largely compatible with fractional crystallization of clinopyroxene and Fe-Ti oxides. Sulfur contents of the homogenized silicate-melt inclusions in clinopyroxene phenocrysts compared with that in the host scoria show that S has been significantly degassed in the erupted products; whereas, Cl has about the same abundance in the inclusions and in host scoria. Fluorine is low (infrequently up to 800 ppm) in the silicate-melt inclusions compared to 2400 ppm in the bulk scoria. Electron microprobe analyses of silicate-melt inclusions show that they have primitive magma compositions (Mg# = 75-91). The composition of the host clinopyroxene phenocrysts varies from typical plinian-related (Mg#???85) to non-plinian related (Mg#???85). The mixed source of the host clinopyroxenes and primitive nature of the silicate-melt inclusions implies that these phenocrysts, in part, may be residual and/or have a polygenetic origin. The similar variation trends of major and minor-elements between homogenized silicate-melt inclusions from the Terzigno scoria, and silicate-melt inclusions in olivine and diopside phenocrysts from plinian eruptions (Marianelli et al., 1995) suggest that the trapped inclusions represent melts similar to those that supplied the plinian and sub-plinian magma chambers. These geochemical characteristics suggest that the Vesuvius magmatic system retained a vestige of the most

    More than 600 000 people are exposed to volcanic risk in the urban areas near the volcano, Vesuvius, and may need to be evacuated if there is renewed volcanic activity. The success of a future evacuation will strongly depend on the level of risk perception and preparedness of the at-risk communities during the current period of quiescence. The volcanic risk perception and preparedness of young people is of particular importance because hazard education programs in schools have been shown to increase the clarity of risk perception and students often share their knowledge with their parents. In order to evaluate young people's risk perception and preparedness for a volcanic crisis, a multiple choice questionnaire was distributed to 400 high-school students in three municipalities located close to the volcano. The overall results suggest that despite a 60-year period of quiescence at Vesuvius, the interviewed students have an accurate perception of the level of volcanic risk. On the other hand, the respondents demonstrate a clear lack of understanding of volcanic processes and their related hazards. Also, the interviewed students show high levels of fear, poor perceived ability to protect themselves from the effects of a future eruption, and insufficient knowledge of the National Emergency Plan for Vesuvian Area (NEPVA). The latter result suggests that in comparison with volcanic crises in other regions, during a future eruption of Vesuvius, there may not be enough time to educate the large number of people living near the volcano about how to appropriately respond. The inadequate risk education and preparedness of respondents implies that a strong effort is needed to improve communication strategies in order to facilitate successful evacuations. Therefore, it is important to take advantage of the present period of quiescence at Vesuvius to improve the accuracy of risk perception of youth in local communities. ?? 2008.

    In this paper experimental gerontology in Italy is reviewed on the basis of research developed in Academic and non Academic Centres. There are several groups across Italy working actively on basic science of aging producing high impact papers with a significant contribution to biogerontology. Some distinguished Italian scientist working abroad is also mentioned. Interesting issues on longevity and interventions on aging (including caloric restriction) and on aging brain are quoted. Relevant studies encompass the (glyco-)oxidative stress as direct damage mechanism and main process of theory of aging, other research lines include IGF-1, mitochondria DNA, obesity/sarcopenia and exercise and also an animal model for aging studies is reported. Notwithstanding financial restrictions and structure deficit the biogerontology research in Italy could be judged as good, but additional resources are necessary to keep this good rank.

    This research aims to understand the prevalence of religious slaughter practices in Italy. Two different ways of slaughtering animals are identified. Conventional slaughter is performed with prior stunning; kosher slaughter is practiced without stunning. Halal slaughter is performed for most animals without stunning. Halal slaughter with prior stunning is acceptable for 5.90% of small ruminants. For Halal slaughter in Italy, the terms "religious slaughter with stunning" and "religious slaughter without stunning" should be used to differentiate religious slaughter practices, keeping animal welfare in perspective.

    2011-01-01

    In the territory of the Campania region (southern Italy), critical rainfall events periodically trigger dangerous fast slope movements involving ashy and pyroclastic soils originated by the explosive phases of the Mt. Somma-Vesuvius volcano and deposited along the surrounding mountain ranges. In this paper, an integration of engineering-geological and geophysical measurements is presented to characterize unsaturated pyroclastic samples collected in a test area on the Sarno Mountains (Salerno and Avellino provinces, Campania region). The laboratory analyses were aimed at defining both soil water retention and electrical resistivity curves versus water content. From the matching of the experimental data, a direct relationship between electrical resistivity and matric suction is retrieved for the investigated soil horizons typical of a ash-fall pyroclastic succession. The obtained relation turns out to be helpful in characterizing soils up to close saturation, which is a critical condition for the trigger of slo...

The movement grew from the initial 25 wineries to the 21,000 that participate today in opening their doors to the public, while visitors grew in numbers from a couple of hundred, 20 years ago, to the current 4 to 6 million. Wine tourists can be divided into four main groups: wine tourists by chance, classic wine tourists, talent scouts, and lovers of luxury. Each group is examined according to its consumption, its conduct, and its expectations. Wine tourism in Italy boasts around 170 territorial networks: “Strade del Vino” (wine routes regulated by law. After an initial pioneer phase during which preexisting wineries adapted to the growing number of tourists, modern-day wineries were created with bespoke areas for the welcoming of visitors. Wineries in Italy can be classified into the following main types: “functional wineries” that concentrate on productive efficiency; “cathedrals” – renovated historic buildings or modern “starchitecture” designs in which esthetics play an important role; wineries with a “strong identity” linked to the owner or wine producer with the special imprint of his or her personal wine making passion. Other features of Italian wine territories such as food and wellness centers not to speak of the ever present cultural heritage also play a part in attracting wine tourists. Lastly, an evaluation is made of business and communication aspects with a specific reference to the use of the web. Keywords: wine tourism, Italian wineries, winery tours, wine roads of Italy

    Silicate-melt inclusions from lavas and pyroclastics from a selected suite of pre-A.D. 1631 interplinian Mt. Somma-Vesuvius lavas and scoria have been experimentally homogeneized and studied by microthermometry, electron microprobe (EMPA) and secondary-ion mass spectrometry (SIMS) to examine pre-eruptive volatile content and magma evolution. The melt inclusions have a bubble about 0.06% their volume, uncommonly contain non-condensable gas but do not contain any dense fluid phases. Clinopyroxene-hosted inclusions yield homogenization temperatures (Th) from 1170 to 1260??C, most between 1220 and 1240??C; plagiclase-hosted inclusions have Th from 1210 to 1230??C; these values are typical for the Vesuvius environment. The dominant factor controlling major element variability in the inclusions is clinopyroxene fractionation; MgO varies from 5 to 3 wt%, SiO2 varies from 60 to 48 wt%. total alkalis vary from 15 to 4 wt%, and CaO varies from 13 to 5 wt%. H2O varies from 2.7 to 0.6 wt% and is decoupled from incompatible element evolution suggesting vapor saturation during trapping. Chlorine and F vary from 1.- wt% to 0 and 0.63 to 0 wt%, respectively. Bulk rock and limited matrix glass analyses show that the lavas lost about half of their F and Cl content except for the A.D. 472-1631 lava which contains similar Cl abundances as the bulk rock. SO3 varies from 0.5 to 0 wt% and compared with matrix glass and bulk rock demonstrate that the lavas have lost essentially all sulfur. The samples can be classified into three age groups, ??? 25 000 yr B.P., 25 000-17 000 yr B.P., and A.D. 472-1631. There is a systematic increase in some components, e.g., total alkalis, SO3, Cl, Li, B, and Sr with the youth of the sample and a decrease in others, e.g., Zr and Y. However, on average these samples seem less evolved than later A.D. 1631-1944 lavas.

    Highly catastrophic explosive eruptions are supplied by Si-rich magmas, generated at shallower level in crust by the evolution of mantle liquids. The timescale of these evolution processes is a crucial factor, because of its control on the length of volcano repose interval leading to high explosive events. Campi Flegrei and Somma-Vesuvius alkaline volcanic systems, located respectively at few kilometers west and east of Neapolitan metropolitan area, produced a variety of eruptions ranging from not explosive lava flows and domes to highly destructive eruptions. Both these high risk volcanoes are in repose time since the last eruption occurred in the 1538 and 1944 BP, respectively. Since that time, the volcanoes experienced fumarolic activity, low level of seismicity with rare earthquakes swarms, as well as two bradyseismic crisis (1969-1972 and 1982-1984) localized in the center of Campi Flegrei caldera, that generated a net uplift of 3.5 m around the town of Pozzuoli. A wide low velocity layer interpreted as an extended magmatic body has been detected at 8-10 km depth beneath these volcanoes by seismic data. The capability of this reservoir to erupt explosively again strongly depends on magma differentiation degree, therefore the knowledge of the time lapse necessary at not explosive mafic liquids to differentiate toward explosive magmas is very crucial to predict the size of a possible short-term future eruption in Campanian area. Our petrologic data indicate that a multi-depth supply system was active under the Campanian Plain since 39 ka. Fractional crystallization during magma cooling associated with upward migration of less dense evolved liquids appears to be the prevalent differentiation process. Our results indicate that huge steam exolution occurred during the late stage of trachyte and phonolite crystallization thus accounting for the high Volcanic Explosivity Index (VEI) of eruptions supplied by these melts. Moreover our CSD data on phenocrysts reveal

    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.

    Defining the magma storage conditions of a volcanic system is a major goal in modern volcanology due to its direct implications for the style of a possible eruption, and thus on the associated risk of any crisis and the necessary management and mitigation strategies. Below 200 MPa and at equivalent depths, the strongly non-ideal behaviour of the H-C-O-S-Cl-F system in the silicate melt causes unmixing of the fluid phase to form an H2O-rich vapour and a hydrosaline phase in equilibrium with the silicate melt, both responsible for buffering the chlorine (Cl) concentration. Following this equilibrium, the Cl concentration in melts may be used as a geobarometer for alkaline magmas. Systematic application of this method to the main explosive eruptions of Mount Somma-Vesuvius highlights two main magma ponding zones, at ~180-200 and ~100 MPa. At these pressures, the maximum pre-eruptive H2O contents for the different magma compositions can be estimated; the results obtained, largely in agreement with the current literature, therefore confirm the validity of the method. The Cl geobarometer may help scientists to define the variation of the magmatic reservoir location through time and thus provide strong constraints on pre-eruptive conditions, which are of utmost importance for volcanic crisis management.

  17. Pyroclastic deposits as a guide for reconstructing the multi-stage evolution of the Somma-Vesuvius Caldera

    Cioni, Raffaello; Santacroce, Roberto; Sbrana, Alessandro

    The evolution of the Somma-Vesuvius caldera has been reconstructed based on geomorphic observations, detailed stratigraphic studies, and the distribution and facies variations of pyroclastic and epiclastic deposits produced by the past 20,000years of volcanic activity. The present caldera is a multicyclic, nested structure related to the emptying of large, shallow reservoirs during Plinian eruptions. The caldera cuts a stratovolcano whose original summit was at 1600-1900m elevation, approximately 500m north of the present crater. Four caldera-forming events have been recognized, each occurring during major Plinian eruptions (18,300 BP "Pomici di Base", 8000 BP "Mercato Pumice", 3400 BP "Avellino Pumice" and AD 79 "Pompeii Pumice"). The timing of each caldera collapse is defined by peculiar "collapse-marking" deposits, characterized by large amounts of lithic clasts from the outer margins of the magma chamber and its apophysis as well as from the shallow volcanic and sedimentary units. In proximal sites the deposits consist of coarse breccias resulting from emplacement of either dense pyroclastic flows (Pomici di Base and Pompeii eruptions) or fall layers (Avellino eruption). During each caldera collapse, the destabilization of the shallow magmatic system induced decompression of hydrothermal-magmatic and hydrothermal fluids hosted in the wall rocks. This process, and the magma-ground water interaction triggered by the fracturing of the thick Mesozoic carbonate basement hosting the aquifer system, strongly enhanced the explosivity of the eruptions.

    The stratigraphic succession of the Pomici di Avellino Plinian eruption from Somma-Vesuvius has been studied through field and laboratory data in order to reconstruct the eruption dynamics. This eruption is particularly important in the Somma-Vesuvius eruptive history because (1) its vent was offset with respect to the present day Vesuvius cone; (2) it was characterised by a distinct opening phase; (3) breccia-like very proximal fall deposits are preserved close to the vent and (4) the pyroclastic density currents generated during the final phreatomagmatic phase are among the most widespread and voluminous in the entire history of the volcano. The stratigraphic succession is, here, divided into deposits of three main eruptive phases (opening, magmatic Plinian and phreatomagmatic), which contain five eruption units. Short-lived sustained columns occurred twice during the opening phase (Ht of 13 and 21.5 km, respectively) and dispersed thin fall deposits and small pyroclastic density currents onto the volcano slopes. The magmatic Plinian phase produced the main volume of erupted deposits, emplacing white and grey fall deposits which were dispersed to the northeast. Peak column heights reached 23 and 31 km during the withdrawal of the white and the grey magmas, respectively. Only one small pyroclastic density current was emplaced during the main Plinian phase. In contrast, the final phreatomagmatic phase was characterised by extensive generation of pyroclastic density currents, with fallout deposits very subordinate and limited to the volcano slopes. Assessed bulk erupted volumes are 21 × 106 m3 for the opening phase, 1.3-1.5 km3 for the main Plinian phase and about 1 km3 for the final phreatomagmatic phase, yielding a total volume of about 2.5 km3. Pumice fragments are porphyritic with sanidine and clinopyroxene as the main mineral phases but also contain peculiar mineral phases like scapolite, nepheline and garnet. Bulk composition varies from phonolite (white

    Intense explosive activity occurred repeatedly at Vesuvius during the nearly 1,600-year period between the two Plinian eruptions of Avellino (3.5 ka) and Pompeii (79 A.D.). By correlating stratigraphic sections from more than 40 sites around the volcano, we identify the deposits of six main eruptions (AP1-AP6) and of some minor intervening events. Several deposits can be traced up to 20 km from the vent. Their stratigraphic and dispersal features suggest the prevalence of two main contrasting eruptive styles, each involving a complex relationship between magmatic and phreatomagmatic phases. The two main eruption styles are (1) sub-Plinian to phreato-Plinian events (AP1 and AP2 members), where deposits consist of pumice and scoria fall layers alternating with fine-grained, vesiculated, accretionary lapilli-bearing ashes; and (2) mixed, violent Strombolian to Vulcanian events (AP3-AP6 members), which deposited a complex sequence of fallout, massive to thinly stratified, scoria-bearing lapilli layers and fine ash beds. Morphology and density variations of the juvenile fragments confirm the important role played by magma-water interaction in the eruptive dynamics. The mean composition of the ejected material changes with time, and shows a strong correlation with vent position and eruption style. The ranges of intensity and magnitude of these events, derived by estimations of peak column height and volume of the ejecta, are significantly smaller than the values for the better known Plinian and sub-Plinian eruptions of Vesuvius, enlarging the spectrum of the possible eruptive scenarios at Vesuvius, useful in the assessment of its potential hazard.

    Shear wave velocities of the crust and upper mantle are defined beneath the Roccamonfina volcano and surrounding Apennines (southern Italy) from the simultaneous nonlinear inversion of the local group velocity dispersion data, obtained from seismic events recorded in 1988-2004 at Roccamonfina station of the INGV-RSNC network, and regional dispersion data obtained in previous studies. The main features of the representative VS models are a carbonatic basement and a low velocity zone at 6-10 km of depth. The sedimentary succession is ~5 km thick below the Roccamonfina volcano and lays above a high VS (3.8 km/s) ascribable to solidified magma body, while it is ~10 km thick below the surrounding Apennines. A low velocity layer with an average thickness of 10 km is detected below the Roccamonfina volcano which can be associated with the presence of partial melting and interpreted as magmatic reservoir. Such low velocity layer, also found below the surrounding Apennines but with a reduced thickness of 2-3 km, extends to the Campanian Plain and to the Neapolitan volcanic area, from Campi Flegrei to Somma-Vesuvius.

    Comprehensive reviews are given for the major volcanic systems that occur in the greater metropolitan area of Naples, southern Italy; Mt. Somma-Vesuvius to the east and the Campi Flegrei volcanic system to the west. Also included in the review is a detailed discussion of the large, highly explosive Campania Volcanic Zone (CVZ) ignimbrite events. These volcanic areas have been studied for more than 100 years, yet significant differences of opinion exist related to fundamental issues of origin and distribution. We present some alternative views related to petrogenesis on some issues based on more than 25 years of research. The relationship between risk assessment and management that impacts the threatened society or culture and the past and ongoing fundamental volcanological research is an essential part of the science. Countries with limited resources may be forced to accept an increased risk but even highly industrialized societies may not be able to completely eliminate deaths from volcanic eruptions. Scientific studies of the hazardous regions should be comprehensive and include reasonable alternative interpretations as this information reveals the level of confidence that must be conveyed to the public officials. The authors review the state of the art of risk assessment and management of the volcanic hazards in the Neapolitan region in light of the review of research.

    New volcanological studies allow reconstruction of the eruption dynamics of the Pomici di Mercato eruption (ca 8,900 cal. yr B.P.) of Somma-Vesuvius. Three main Eruptive Phases are distinguished based on two distinct erosion surfaces that interrupt stratigraphic continuity of the deposits, indicating that time breaks occurred during the eruption. Absence of reworked volcaniclastic deposits on top of the erosion surfaces suggests that quiescent periods between eruptive phases were short perhaps lasting only days to weeks. Each of the Eruptive Phases was characterised by deposition of alternating fall and pyroclastic density current (PDC) deposits. The fallout deposits blanketed a wide area toward the east, while the more restricted PDC deposits inundated the volcano slopes. Eruptive dynamics were driven by brittle magmatic fragmentation of a phonolitic magma, which, because of its mechanical fragility, produced a significant amount of fine ash. External water did not significantly contribute either to fragmentation dynamics or to mechanical energy release during the eruption. Column heights were between 18 and 22 km, corresponding to mass discharge rates between 1.4 and 6 × 107 kg s-1. The estimated on land volume of fall deposits ranges from a minimum of 2.3 km3 to a maximum of 7.4 km3. Calculation of physical parameters of the dilute pyroclastic density currents indicates speeds of a few tens of m s-1 and densities of a few kg m-3 (average of the lowermost 10 m of the currents), resulting in dynamic pressures lower than 3 kPa. These data suggest that the potential impact of pyroclastic density currents of the Pomici di Mercato eruption was smaller than those of other Plinian and sub-Plinian eruptions of Somma-Vesuvius, especially those of 1631 AD and 472 AD (4-14 kPa), which represent reference values for the Vesuvian emergency plan. The pulsating and long-lasting behaviour of the Pomici di Mercato eruption is unique in the history of large explosive eruptions of

    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.

  7. P-wave velocity and density structure beneath Mt. Vesuvius: a magma body in the upper edifice?

    Full Text Available A high-resolution image of the compressional wave velocity and density structure in the shallow edifice of Mount Vesuvius has been derived from simultaneous inversion of travel times and hypocentral parameters of local earthquakes and from gravity inversion. The robustness of the tomography solution has been improved by adding to the earthquake data a set of land based shots, used for constraining the travel time residuals. The results give a high resolution image of the P-wave velocity structure with details down to 300-500 m. The relocated local seismicity appears to extend down to 5 km depth below the central crater, distributed into two clusters, and separated by an anomalously high Vp region positioned at around 1 km depth. A zone with high Vp/Vs ratio in the upper layers is interpreted as produced by the presence of intense fluid circulation alternatively to the interpretation in terms of a small magma chamber inferred by petrologic studies. In this shallower zone the seismicity has the minimum energy, whilst most of the high-energy quakes (up to Magnitude 3.6 occur in the cluster located at greater depth. The seismicity appears to be located along almost vertical cracks, delimited by a high velocity body located along past intrusive body, corresponding to remnants of Mt. Somma. In this framework a gravity data inversion has been performed to study the shallower part of the volcano. Gravity data have been inverted using a method suitable for the application to scattered data in presence of relevant topography based on a discretization of the investigated medium performed by establishing an approximation of the topography by a triangular mesh. The tomography results, the retrieved density distribution, and the pattern of relocated seismicity exclude the presence of significant shallow magma reservoirs close to the central conduit. These should be located at depth higher than that of the base of the hypocenter volume, as evidenced by

    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. Seismic activity and thermal regime of low temperature fumaroles at Mt. Vesuvius in 2004-2011: distinguishing among seismic, volcanic and hydrological signals

    2013-11-01

    Full Text Available Seismological, soil temperature and hydrological data from Mt. Vesuvius are collected to characterize the present-day activity of the volcanic/hydrothermal system and to detect possible unrest-related phenomena. We present patterns of seismicity and soil temperature in the crater area during the period February 2004-December 2011. The temporal distribution of number and depth of Volcano-Tectonic earthquakes and the energy release are considered. Hourly data of soil temperature have been acquired since January 2004 in different locations along the rim and within the crater. The observed changes of temperature are studied to establish a temporal-based correlation with the volcanic activity and/or with external forcing, as variations of the regional and local stress field acting on the volcano or meteorological phenomena. The comparison between seismic activity and temperature data highlights significant variations possibly related to changes in fluid circulation in the hydrothermal system of the volcano. The common continuous observations start just before a very shallow earthquake occurred in August 2005, which was preceded by a thermal anomaly. This coincidence has been interpreted as related to fluid-driven rock fracturing, as observed in other volcanoes. For the successive temporal patterns, the seismicity rate and energy release are characterized by slight variations accompanied by changes in temperature. This evidence of reactivity of the fumarole thermal field to seismic strain can be used to discriminate between tectonic and volcanic signals at Mt. Vesuvius.

    Radiocarbon dating of short-lived sample materials is a useful tool applied to date deposits of volcanic eruptions. Several archaeological sites discovered and excavated in Campania witnessed important volcanic eruptions, which occurred in the Copper and Middle Bronze Ages. These eruptions come from the Somma-Vesuvius complex and the Phlaegrean Fields caldera. At least four Plinian eruptions have been identified in the eruptive history of Somma-Vesuvius, interspersed by interplinian events, called protohistoric, which occurred between Avellino and Pompeii. At S. Paolo Belsito a stratigraphic sequence below Avellino and above the first two protohistoric events after Avellino were highlighted; while Nola (Naples) gives new information on the chronology of Avellino. Sites like Caivano and Gricignano D'Aversa, involved by the Agnano 3, Paleoastroni 2 and Agnano Monte Spina eruptions were highlighted and investigated. In this work, we want to clarify the chronology of some eruptions by comparing our results with previous data. Charcoal, bone and seed samples were collected, treated and measured at the CIRCE laboratory in Caserta.

    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. Copyright 2000 John Wiley & Sons, Inc.

  17. Current and future trends of Volcanology in Italy and abroad

    Science.gov (United States)

    Papale, P.

    2010-12-01

    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

  18. Petrogenesis and tectonic setting of the Roman Volcanic Province, Italy

    Beccaluva, L.; Di Girolamo, P.; Serri, G.

    1991-01-01

    The volcanism in the Roman Province of Italy can be modelled by the partial melting of heterogeneously enriched mantle sources. The heterogeneity was created by materials derived from a subducted slab which can still be traced geophysically beneath the central Apennines. New petrographical and chemical data are presented for the high-K calc-alkaline and the shoshonitic volcanics of the Campania region. Primary magmas are present only locally. The existence of spatial zonation in the volcanism of Campania is documented for the first time. The shoshonitic, leucite-basanitic and leucititic volcanics of the Phlegraean Fields-Procida-Ischia and the Somma-Vesuvius areas are, at similar degrees of evolution, about two times richer in Nb and Ba than those of northwestern Campania and the Latium part of the Roman Province. Accordingly, distinct north-western and south-eastern subprovinces can be defined. The evaluation of enrichment factors, that is the abundance ratio between the average contents of each element in the relatively primitive lavas of the low K- and the high K suites, shows that the mantle sources prior to K-metasomatism were different in the two sub-provinces of the Roman Province. In the north-western one, they resembled the sources of ocean-island tholeiites and moderately enriched MOR-basalts. In the south-east they were similar to those of ocean island alkaline lavas and enriched MORB's. Modelling based on K, P, Ce, Sr, Rb, Ba, Th, Sm, Eu, Gd, Y, Nb and {87 Sr}/{86 Sr} was carried out. It indicates that the range of mantle sources of the volcanics in northwestern Campania and Latium can be modelled by the addition of 3 to 20% of materials derived by partial melting of carbonaceous pelites to a Sr-enriched mantle wedge comparable to the Honolulu mantle source least enriched in Nb. The production of Sr-enriched mantle wedge requires either the action of fluids produced by dehydration of subducted oceanic crust, or a small amount of metasomatism caused by

    The Campania (Italy) coasts are characterized by the presence of several volcanoes. The island of Ischia, located at the northwestern end of the Gulf of Naples, belongs to the Neapolitan Volcanic District together with Phlegrean Fields and Vesuvius, having all these Pleistocene volcanoes erupted in historical times, and it is characterized by diffuse hydrothermal phenomena The island represents the emergent part of a more extensive volcanic area developed mainly westward of the island, with underwater volcanoes aligned along regional fault patterns. The activity of Ischia volcano is testified by the occurrence of eruptions in historical times, the presence of intense hydrothermal phenomena, and by seismic activity (e.g. the 1883 Casamicciola earthquake). Ischia is populated by about 50,000 inhabitants increasing, mainly in the summer, due to thriving tourism business, partially due to its active volcanic state. Hazard assessment at active, densely populated volcanoes is critically based on knowledge of the volcanoes past behavior and the definition of its present state. As a contribution to the definition of the present state of the Ischia island volcano, we obtain a model of the shallow crust using geophysical observables through seismic tomography and 3D gravity inversion. In particular we use travel times collected during the Serapis experiment on the island and its surroundings and free air anomaly. A new 3D gravity inversion procedure has been developed to take better into account the shape and the effects of topography approximating it by a triangular mesh. Below each triangle, a sequence of triangular prisms is built, the uppermost prism having the upper face coincident with the triangle following the topography. The inversion is performed searching for a regularized solution using the minimum norm stabilizer. The main results inferable from the 3D seismic and gravity images are the definition of the caldera rims hypothesize by many authors along the

    One of the current stakes in modern volcanology is the definition of magma storage conditions which has direct implications on the eruptive style and thus on the associated risks and the management of likely related crisis. In alkaline differentiated magmas, chlorine (Cl), contrary to H2O, occurs as a minor volatile species but may be used as a geobarometer. Numerous experimental studies on Cl solubility have highlighted its saturation conditions in silicate melts. The NaCl-H2O system is characterized by immiscibility under wide ranges of pressure, temperature and NaCl content (Somma-Vesuvius, Phlegrean Fields and Ischia. We have analysed the products of the representative explosive eruptions of each volcano, including Plinian, sub-Plinian and strombolian events. We have focussed our research on the earliest emitted, most evolved products of each eruption, likely representing the shallower, fluid-saturated portion of the reservoir. As the studied eruptions cover the entire eruptive history of each volcanic system, the results allow better constraining the evolution through time of the shallow plumbing system. We highlighted for Mount Somma - Vesuvius two magma ponding zones, at ~170-200 MPa and ~105-115 MPa, alternatively active in time. For Phlegrean Fields, we evidence a progressive deepening of the shallow reservoirs, from the Campanian Ignimbrite (30-50 MPa) to the Monte Nuovo eruption (115 MPa). Only one eruption was studied for Ischia, the Cretaio eruption, that shows a reservoir at 140 MPa. The results on pressure are in large agreement with literature. The Cl geobarometer may help scientists to define the reservoir dynamics through time and provide strong constraints on pre-eruptive conditions, of utmost importance for the interpretation of the monitoring data and the identification of precursory signals.

    A review of compositional data of the major explosive eruptions of Vesuvius is presented, comparing compositions (major elements) of whole rock with glass shards from the proximal deposits, hopefully useful for long-distance correlation. A critical review of published and new geochronological data is also provided. All available 14C ages are calibrated to give calendar ages useful for the reconstruction of the volcanological evolution of the volcanic complex. The pyroclastic deposits of the four major Plinian eruptions (22,000 yr cal BP "Pomici di Base", 8900 yr cal BP "Mercato Pumice", 4300 yr cal BP "Avellino Pumice", and A.D. 79 "Pompeii Pumice") are widely dispersed and allow a four-folded, Plinian to Plinian, stratigraphic division: 1. B-M (between Pomici di Base and Mercato); 2. M-A (between Mercato and Avellino); 3. A-P (between Avellino and Pompeii); 4. P-XX (from the Pompeii Pumice to the last erupted products of the XXth century). Within each interval, the age, lithologic and compositional features of pyroclastic deposits of major eruptions, potentially useful for tephrostratigraphic purposes on distal areas, are briefly discussed. The Vesuvius rocks are mostly high Potassic products, widely variable in terms of their silica saturation. They form three groups, different for both composition and age: 1. slightly undersaturated, older than Mercato eruption; 2. mildly undersaturated, from Mercato to Pompeii eruptions; 3. highly undersaturated, younger than Pompeii eruption. For whole rock analyses, the peculiar variations in contents of some major and trace elements as well as different trends in element/element ratios, allow a clear, unequivocal, easy diagnosis of the group they belong. Glass analyses show large compositional overlap between different groups, but selected element vs. element plots are distinctive for the three groups. The comparative analysis of glass and whole rock major element compositions provides reliable geochemical criteria helping

    Italy now ranks 8th in the list of countries worst hit by AIDS. The relatively low figures for homosexual AIDS cases give no cause for complacency. It is not known yet if the message about 'safe sex' has got across to homosexuals, or if there has been underreporting and the numbers with AIDS will start soon to show the same rising curve as that for drug users. The Vatican, as was always expected, has said 'no' to the use of condoms to combat the spread of HIV, even though its use would not be to avoid conception but to prevent disease. Many doctors working in the field resent the lack of consultation and communication between Rome and the regions. But Italian health services are decentralized; the 21 regional health authorities are autonomous bodies. They have never looked to central government for specific directions, but they do desperately need extra funding. Their literature has been important as means of countering 'disinformation' from the press, often prone to sensationalism. Discrimination against children of parents infected with HIV has occured in schools and frequently seropositive employees have been fired. Local authorities are now making great efforts to impart the correct information. The Italian family planning association, UNICEMP, plays a supportive role in the education and information campaign. Many voluntary organizations provide counseling. The government national commission on AIDS set up a free telephone service where experts are available to answer questions from the public. But although 18,000 calls were made in the 1st 6 weeks of opening, hardly any inqueries at all came from those most at risk--the drug users.

    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.

    This paper discusses the abundance, speciation and mobility of As in groundwater systems from active volcanic areas in Italy. Using literature data and new additional determinations, the main geochemical processes controlling the fate of As during gas-water-rock interaction in these systems are examined. Arsenic concentrations in the fluids range from 0.1 to 6940 {mu}g/l, with wide differences observed among the different volcanoes and within each area. The dependence of As content on water temperature, pH, redox potential and major ions is investigated. Results demonstrate that As concentrations are highest where active hydrothermal circulation takes place at shallow levels, i.e. at Vulcano Island and the Phlegrean Fields. In both areas the dissolution of As-bearing sulphides is likely to be the main source of As. Mature Cl-rich groundwaters, representative of the discharge from the deep thermal reservoirs, are typically enriched in As with respect to SO{sub 4}-rich ''steam heated groundwaters''. In the HCO{sub 3}{sup -} groundwaters recovered at Vesuvius and Etna, aqueous As cycling is limited by the absence of high-temperature interactions and by high-Fe content of the host rocks, resulting in oxidative As adsorption. Thermodynamic modelling suggests that reducing H{sub 2}S-rich groundwaters are in equilibrium with realgar, whereas in oxidising environments over-saturation with respect to Fe oxy-hydroxides is indicated. Under these oxidising conditions, As solubility decreases controlled by As co-precipitation with, or adsorption on, Fe oxy-hydroxides. Consistent with thermodynamic considerations, As mobility in the studied areas is enhanced in intermediate redox environments, where both sulphides and Fe hydroxides are unstable.

    Pyroclastic density currents (PDCs) generated during the Plinian eruption of the Pomici di Avellino (PdA) of Somma-Vesuvius were investigated through field and laboratory studies, which allowed the detailed reconstruction of their eruptive and transportation dynamics and the calculation of key physical parameters of the currents. PDCs were generated during all the three phases that characterised the eruption, with eruptive dynamics driven by both magmatic and phreatomagmatic fragmentation. Flows generated during phases 1 and 2 (EU1 and EU3pf, magmatic fragmentation) have small dispersal areas and affected only part of the volcano slopes. Lithofacies analysis demonstrates that the flow-boundary zones were dominated by granular-flow regimes, which sometimes show transitions to traction regimes. PDCs generated during eruptive phase 3 (EU5, phreatomagmatic fragmentation) were the most voluminous and widespread in the whole of Somma-Vesuvius’ eruptive history, and affected a wide area around the volcano with deposit thicknesses of a few centimetres up to more than 25 km from source. Lithofacies analysis shows that the flow-boundary zones of EU5 PDCs were dominated by granular flows and traction regimes. Deposits of EU5 PDC show strong lithofacies variation northwards, from proximally thick, massive to stratified beds towards dominantly alternating beds of coarse and fine ash in distal reaches. The EU5 lithofacies also show strong lateral variability in proximal areas, passing from the western and northern to the eastern and southern volcano slopes, where the deposits are stacked beds of massive, accretionary lapilli-bearing fine ash. The sedimentological model developed for the PDCs of the PdA eruption explains these strong lithofacies variations in the light of the volcano’s morphology at the time of the eruption. In particular, the EU5 PDCs survived to pass over the break in slope between the volcano sides and the surrounding volcaniclastic apron-alluvial plain

    2010-08-01

    Data collected at Somma-Vesuvius during the 1998-1999 radon surveys have been revisited and reinterpreted in light of recent geophysical and geochemical information. The duration of selected radon anomalies, together with the decay properties of radon, have been used to estimate the permeability and porosity of rocks of the deep hydrothermal system. The current local cyclic seismicity is explained by means of a double convective-cell model. Convective cells are separated by a low-permeability horizon located at about 2-2.5 km below sea level. Fluids convecting within the upper cells show temperatures ranging 300-350°C. Rock permeabilities in this sector are estimated on the order of 10-12 m2, for porosities ( ϕ) of about 10-5 typical of a brittle environment where fluid velocities may reach ˜800 m/day. Fluid temperatures within the lower cells may be as high as 400-450°C, consistent with supercritical regimes. The hydrodynamic parameters for these cells are lower, with permeability k ˜ 10-15 m2, and porosity ranging from 10-6 to 10-7. Here, fluid motion toward the surface is controlled by the fracture network within a porous medium approaching brittle-ductile behaviour, and fluid velocities may reach ˜1,800 m/day. The low-permeability horizon is a layer where upper and lower convecting cells converge. In this region, fluids (convecting both at upper and lower levels) percolate through the wallrock and release their brines. Due to self-sealing processes, permeability within this horizon reaches critical values to keep the fluid pressure near lithostatic pressure (for k ˜ 10-18 m2). Deep fluid pressure buildups precede the onset of hydrothermally induced earthquakes. Permeability distribution and rock strength do not exclude that the next eruption at Somma-Vesuvius could be preceded by a seismic crisis, eventually leading to a precursory phreatic explosion. The coupling of these mechanisms has the potential of inducing pervasive failure within rocks of the

    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. Published by Elsevier Inc.

    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.

    We simulate the volcanic activity of a basaltic stratovolcano by using a cellular automaton model where magma is allowed to rise through self-organized crack networks. Magma rises toward the surface by filling connected paths of fractures until the magma's density is less than, or equal to that of the surrounding rocks. If magma enters a less dense rock layer, it cools and thus solidifies; as a result, the local density profile is modified, and solid filled dikes are formed. We simulate the temporal evolution of such high density pathway of dikes which magma may eventually utilize to reach the surface with the occurrence of an eruption. Magma degassing is also taken into account by means of the relationship between the pressure-controlled water solubility and the lithostatic pressure. We study the statistical properties of the automaton by varying the model parameters and, in particular, the thickness of the uppermost rock layer, which controls the buoyancy rate of magma rise because of its low value of density. We show that, if the initial rock density profile is restored after each eruption because, for example, piecemeal or chaotic collapses, a characteristic timescale appears in the inter-event repose time distribution, which represents the average time that magma takes to form an high density pathway through the less dense rock layer. An application of the model to the statistics of the eruptive activity of the Somma-Vesuvius volcano for the 1631-1944 period is discussed.

    Researches are currently focused on large intensity and stable eruptive columns as for Plinian event. But the large variability in deposits issued from sub-Plinian eruptions needs more observations, theoretical and experimental investigations to be better described and enhances criteria of classification and the knowledge on processes at the origin of this unsteadiness of various timescales. Here, we focus on the well-known example of sub-Plinian eruption exhibiting by Mount Somma-Vesuvius: the Greenish Pumice eruption (GP). On the basis of coupled geochemical and textural analyses we investigate the volatile behavior (H2O, CO2 and halogen (F, Cl)) to better constrain (1) the magma reservoir location and pre-eruptive state and (2) the sub-Plinian eruptive style through a detailed study of the degassing processes in relation with the dynamic of the eruptive column. Results evidence that Cl act as a geobarometer for the trachytic-phonolitic melt involved during the eruption indicating that magma reservoir was at 100 MPa (Cl buffer value: 5300 ±130 ppm) and wholly H2O-saturated (pre-eruptive H2O content between 3.8 and 5.2 wt%). The eruption dynamic is clearly explained by open-system degassing processes responsible of the eruptive column instability, correlated to textural heterogeneities of the eruptive products reflecting conduit heterogeneity (smaller diameter and higher horizontal gradient in magma ascent velocity).

    This study is based on the skeletal remains of an adult female from the ancient city of Herculaneum (Naples, Italy), who was a victim of the eruption of the nearby Vesuvius Volcano on 24-25 August, AD 79. Examination of the maxillofacial region revealed evidence of unilateral condylar fracture and dislocation, as well as traumatic dental injuries. The injuries observed might have been the consequence of a direct blow to the mental region that was transmitted in a direction that raised the mandible, causing an indirect fracture in the right condylar neck when the condylar head collided directly with the temporal glenoid fossa. This indirect impact also resulted in partial fracture of three dental crowns due to the violent impact of the arches between them, and the sharp impact together of the upper and lower teeth. It is suggested that these injuries were sustained due to an accidental fall when the individual was between 7 and 15 years old, which is supported by the morphology, location and extension of the injuries, and the characterization of the impact. These results are an illustration of how dental anthropology and forensic approaches can be applied with great benefit to archaeological skeletal remains. © 2015 John Wiley & Sons A/S.

    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.

  5. Influences of urban fabric on pyroclastic density currents at Pompeii (Italy): 2. Temperature of the deposits and hazard implications

    2007-05-01

    During the A.D. 79 eruption of Vesuvius, Italy, the Roman town of Pompeii was covered by 2.5 m of pyroclastic fall pumice and then partially destroyed by pyroclastic density currents (PDCs). Thermal remanent magnetization measurements performed on the lithic and roof tile fragments embedded in the PDC deposits allow us to quantify the variations in the temperature (Tdep) of the deposits within and around Pompeii. These results reveal that the presence of buildings strongly influenced the deposition temperature of the erupted products. The first two currents, which entered Pompeii at a temperature around 300-360°C, show drastic decreases in the Tdep, with minima of 100-140°C, found in the deposits within the town. We interpret these decreases in temperature as being the result of localized interactions between the PDCs and the city structures, which were only able to affect the lower part of the currents. Down flow of Pompeii, the lowermost portion of the PDCs regained its original physical characteristics, emplacing hot deposits once more. The final, dilute PDCs entered a town that was already partially destroyed by the previous currents. These PDCs left thin ash deposits, which mantled the previous ones. The lack of interaction with the urban fabric is indicated by their uniform temperature everywhere. However, the relatively high temperature of the deposits, between 140 and 300°C, indicates that even these distal, thin ash layers, capped by their accretionary lapilli bed, were associated with PDCs that were still hot enough to cause problems for unsheltered people.

  6. Automatized near-real-time short-term Probabilistic Volcanic Hazard Assessment of tephra dispersion before eruptions: BET_VHst for Vesuvius and Campi Flegrei during recent exercises

    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 temporal 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 named BET_VHst (Selva et al. 2014) for short-term PVHA of volcanic tephra dispersal based on automatic interpretation of measures from the monitoring system and physical models of tephra dispersal from all possible vent positions and eruptive sizes based on frequently updated meteorological forecasts. 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.

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...

    At the beginning of 2002, there were 1,600,000 foreign-born persons living in Italy; the majority from countries outside Europe. Those residing in the country for working purposes were 800,680. Italy's shift to a tertiary and service-oriented economy has considerably modified the working market, concentrating demand at two extremes: on one hand, a highly specialized workforce, and on the other, a totally unqualified, mobile, and flexible one, which includes most immigrants.

    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.

  16. Seismic hazard maps of Italy

    Full Text Available The Italian "Gruppo Nazionale per la Difesa dai Terremoti" has conducted a project in recent years for assessing seismic hazard in the national territory to be used as a basis for the revision of the current seismic zonation. In this project the data on the major earthquakes were reassessed and a new earthquake data file prepared. Definition of a seismotectonic model for the whole territory, based on a structural-kinematic analysis of Italy and the surrounding regions, led to the definition of 80 seismogenic zones, for which the geological and seismic characteristics were determined. Horizontal PGA and macroseismic intensity were used as seismicity parameters in the application of the Cornell probabilistic approach. The main aspects of the seismic hazard assessment are here described and the results obtained are presented and discussed. The maps prepared show the various aspects of seismic hazard which need to be considered for a global view of the problem. In particular, those with a 475-year return period, in agreement with the specifications of the new seismic Eurocode EC8, can be considered basic products for a revision of the present national seismic zonation.

    The paper describes the experiences in Italy with the CBRN (Chemical Biological Radiological Nuclear) defense mobile laboratories. These laboratories were constructed by the Italian Army and the Italian Fire Brigades. The purpose of these mobile laboratories is to allow quick transport of the labs to the area of crisis in order to support emergency response in case of CBRN events. The differences between two alternative solutions will be developed in the paper. The first solution is when the lab is to be located in the "dangerous area" (this solution was chosen by the Italian Army) and the alternative approach is to place the mobile lab just outside the dangerous area (this approach was selected by the Italian Fire Brigades). One of the most important devices inside the lab is the isolator (also called "glove box") which allows safe ingress and handling of the "suspicious" samples from the external environment. The isolator has a special chamber for transfer of the sample from the outside. The pressure of the isolator is permanently kept below the air pressure inside the lab by means of one (or more) fan. The operators perform the sample preparations or part of the analysis by handling the sample with the gloves. The material flow inside the lab will be described depending on the kind of identification analysis to be done on the samples. Other devices installed on the mobile CBRN laboratories are: biohazard hood (UE regulation, containment level 2); autoclave; freezer; cleaning skid (tanks, pumps, etc.).

  18. Crustal Deformation In Northeastern Italy.

    Zerbini, S.; Romagnoli, C.; Richter, B.; Lago, L.; Domenichini, F.; Simon, D.

    Four permanent GPS stations have been installed in northeastern Italy starting mid 1996. Three stations: Bologna, Medicina and Porto Corsini are located in the south- eastern Po Plain, while the fourth one was set up in the Trieste harbor. The network was installed to monitor vertical crustal movements at tide gauge sites and in sub- siding areas of the Po Plain. At Medicina, since October 1996, it is also operative a superconducting gravimeter periodically controlled by means of absolute gravity mea- surements. The stations, which are distributed around the northern edge of the Adria plate, provide information on vertical and horizontal displacements related to crustal deformation. The temporal behavior of the Adria plate, in response to the convergence of the surrounding regions, has been presumably more complex than a simple horizon- tal displacement and, most likely, involved flexural bending processes. The GPS and the continuous gravity data have been analyzed and interpreted to estimate vertical and horizontal rates at the four sites. The presence of relevant seasonal signals has been identified in the series of station coordinates as well as in the gravity data. These fluc- tuations, if not accounted for, may corrupt the high precision estimate of the long-term trends.

    2011-09-01

    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.

    Full Text Available Abstract Background Immigration is increasing in Italy. In 2003, 2.6 million foreign citizens lived in the country; 52% were men and the majority were young adults who migrated for work. The purpose of this study was to investigate differences in hospitalisation between immigrants and the resident population during the year 2000 in the Lazio region. Methods Hospital admissions of immigrants from Less Developed Countries were compared to those of residents. We measured differences in hospitalisation rates and proportions admitted. Results Adult immigrants have lower hospitalisation rates than residents (134.6 vs. 160.5 per thousand population for acute care; 26.4 vs. 38.3 for day care. However, hospitalisation rates for some specific causes (injuries, particularly for men, infectious diseases, deliveries and induced abortions, ill-defined conditions were higher for immigrants than for residents. Immigrants under 18 years seem to be generally healthy; causes of admission in this group are similar to those of residents of the same age (respiratory diseases, injuries and poisoning. The only important differences are for infectious and parasitic diseases, with a higher proportion among immigrant youths. Conclusion The low hospitalisation rates for foreigners may suggest that they are a population with good health status. However, critical areas, related to poor living and working conditions and to social vulnerability, have been identified. Under-utilisation of services and low day care rates may be partially due to administrative, linguistic, and cultural barriers. As the presence of foreigners becomes an established phenomenon, it is important to evaluate their epidemiological profile, develop instruments to monitor and fulfil their specific health needs and plan health services for a multi-ethnic population.

  3. Some examples of geomorphodiversity in Italy

    Science.gov (United States)

    Panizza, Mario

    2014-05-01

    The concept of geomorphodiversity (Panizza, 2009) is presented: "the critical and specific assessment of the geomorphological features of a territory, by comparing them in a way both extrinsic (comparison of the geomorphological characteristics with those from other territories) and intrinsic (comparison of the geomorphological characteristics with other areas within the territory itself) and taking into account the level of their scientific quality, the scale of investigation and the purpose of the research". A first example concerns the Dolomites: they have been included in the UNESCO World Heritage List because of their exceptional beauty and unique landscape, together with their scientific importance from the geological and geomorphological point of view. They are of international significance for geomorphodiversity, as the classic site for the development of mountains in dolomite limestone and present a wide range of landforms related to erosion, tectonics and glaciation. They represent a kind of high altitude, open air laboratory of geomorphological heritage of exceptional global value, among the most extraordinary and accessible in the world and ideal for researching, teaching, understanding and developing Earth Science theories. The second example concerns the Emilia-Romagna Apennines, candidate for enrolment in the List of European Geoparks: they show a multifaceted and complex image from the international and regional geomorphological (extrinsic and intrinsic geomorphodiversity) point of view and are an educational example for illustrating morphotectonic evolution, stratigraphic and sedimentological sequences and morpholithological peculiarities connected with gypsum karst and clay mass wasting phenomena. The third example concerns the Vesuvius, one of the National Italian Parks: it shows an extrinsic geomorphodiversity mainly referred to the type of eruptions, with some exemplary processes inserted in international volcanic nomenclature; it makes up an

Los estudios vulcanológicos y arqueológicos han requerido, entre otros datos y observaciones, determinar la frecuencia y la naturaleza efusiva o explosiva de las erupciones empleando técnicas de datación y la construcción de una cronología de alta resolución. En este estudio se analizan 14 flujos de eventos eruptivos en el periodo de 79 a 1906 A. D., para los cuales presentamos nuevas dataciones arqueomagnéticas usando el modelo geomagnético SHA.DIF.14k. Las direcciones paleomagnéticas de los flujos se correlacionan con la curva de variación secular, permitiendo revaluar la cronología eruptiva del Vesubio. ENGLISH: Vesuvius Volcano, located in a densely populated area including the cities of Pompeii, Herculaneum and now Naples, is characterized by numerous eruptions separated by periods of quiescence. Information on the frequency and nature of this activity is critical for both volcanological and archaeological studies. Dating techniques in tandem with historical records can provide a high resolution chronology for Vesuvius’ eruption history. In this study, we analyze paleomagnetic data from 14 lava flows dating between AD 79 to 1906 using the recently developed SHA.DIF.14k geomagnetic model. We correlate the paleomagnetic directions of the flows with a new secular variation curve, resulting in a reassessment of the eruptive chronology of Vesuvius.

    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.

    Textural and chemical variations of juvenile clasts are widely observed in pyroclastic deposits. In particular, the co-existence of whitish, pumiceous, and dark grey, scoriaceous, juvenile clasts has been observed in many eruptive units of well-known volcanoes (i.e., Somma-Vesuvius, Vulsini, Colli Albani, Stromboli). Here we report the example of the Tufo Giallo della Via Tiberina (TGVT) pyroclastic succession, which comprises two eruptive units emplaced at ca. 561 and 548 ka, during the early explosive activity of the Sabatini Volcanic District (SVD; Roman Province, central Italy). TGVT deposits, as well as underlying pyroclastic products (FAD, ca. 582 ka), are characterized by coexisting whitish pumice and black-grey scoria clasts showing common phonolitic composition but different textural features: white pumice is highly vesicular, vitrophyric, and contains scarce, > 50 µm-sized, feldspar and clinopyroxene crystals, while black-grey scoria is poorly vesicular, highly crystallized, and contains diffuse leucite phenocrysts. The latter records crystallization under H 2O-undersaturated conditions, as opposed to the vitrophyric texture of white pumice indicating higher temperature and H 2O concentration. On these grounds, a thermally and H 2O-zoned pre-eruptive system has been modelled for the phonolitic magma chambers feeding the early SVD events, in which white pumice and black-grey scoria represent the inner and peripheral portions of the reservoirs, respectively. Extensive leucite + clinopyroxene crystallization in the H 2O-undersaturated, peripheral portions of the reservoirs, resulted in water flux toward the inner zones, where the higher temperature and increasing H 2O content acted to delay crystallization in the white pumice-feeder magma. The withdrawal of white pumice at the eruption onset produced decompression of the peripheral magma, triggering black-grey scoria eruption during the late phases of explosive events.

  9. The magmatic system of Ischia island: another piece in the puzzle of the fluid-saturated, CO2-sustained, Neapolitan volcanism (Southern Italy)

    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.

  10. The possible correlation between dental enamel hypoplasia and a historic natural disaster in the Roman population of Herculaneum (79 AD - central Italy).

    Dental enamel hypoplasia is usually read as a sign of a systematic growth disturbance during childhood. Following the analysis of human teeth from Herculaneum (79 AD, Central Italy), the authors focused on linear enamel hypoplasia (LEH) manifestations in order to delineate a possible correlation between their frequency and distribution and the earthquake that occurred in 62 AD, which is well documented in historical literature. The human remains from Herculaneum were buried at the same time as the Vesuvius eruption and represent an exceptional snapshot of life in the Roman Imperial Age. The Goodman and Rose method (1990) was used for attributing an "age at the moment of stress" for every skeleton in order to delineate the epidemiology of the enamel hypoplasia. When LEH frequency was analysed by age, two different age groups showed relevant patterns of hypoplasia: the first peak was evident in individuals between 14 and 20 years who were younger than 6 years at the time of the 62 AD earthquake, and a second peak was noted in adults of 30 +/- 5 years old, which suggests the presence of another stressful event that occurred 10 years before the earthquake, around 53 AD. The bimodal distribution of enamel hypoplasia could be the consequence of two different historical periods characterized by instability in the food supply, unhygienic conditions, and epidemic episodes; our data suggest that the first peak could be related to a decline in health status as an effect of the 62 AD earthquake. The relationship between recent natural disasters and variations in health status in modern populations is well documented in scientific literature. Our research represents the first attempt to correlate the status of health to an earthquake of known date in an archaeological population.

    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

  20. Postgraduate Courses in Pharmaceutical Medicine in Italy

    Directory of Open Access Journals (Sweden)

    Domenico Criscuolo

    2017-06-01

    Full Text Available Italy has a significant tradition of excellence in the area of clinical trials (CTRs: important achievements in the clinical development of rifampicin and adriamycin, the two most famous drugs discovered in the research laboratories of two Italian pharmaceutical companies, paved the way to the establishment of a culture of clinical development, mainly in the areas of antimicrobials and oncology. Despite the fact that now the Italian market of pharmaceuticals is largely dominated by multinational companies with headquarters outside Italy, the contribution of Italian studies to the clinical development of new drugs is still significant. Indeed, it largely exceeds the percentage of Italian inhabitants versus the ones living in the remaining EU countries, as Italy has about 12% of EU population, but has a 17% share of the EU CTRs. Education in Pharmaceutical Medicine is now a must for all professionals interested to work either in pharma companies or in contract research organizations: several Italian universities are offering high quality courses, and in the last 10 years, more than 1,200 professionals received a postgraduate education in pharmaceutical medicine. This result places Italy on top of countries concerned about the professional education of people involved in drug development and will represent an asset for a larger involvement of Italian clinical sites in the global process of clinical research.

  9. Robust date for the Bronze Age Avellino eruption (Somma-Vesuvius): 3945 ± 10 calBP (1995 ± 10 calBC)

    Science.gov (United States)

    Sevink, Jan; van Bergen, Manfred J.; van der Plicht, Johannes; Feiken, Hendrik; Anastasia, Carmela; Huizinga, Annika

    2011-05-01

    We found Bronze Age lake sediments from the Agro Pontino graben (Central Italy) to contain a thin (2-3 cm) continuous tephra layer composed of lithics, crystals and minor volcanic glass. Tephrochronological and compositional constraints strongly suggest that this layer represents the Avellino pumice eruption, which has also been identified in Central Italian lake cores. Its provenance is corroborated by electron-microprobe analyses performed on juvenile pumice grains, showing that the tephra layer is probably the distal equivalent of the EU2 event of the Avellino eruption. We used multiple 14C age estimations of two lacustrine sequences with intercalated tephra layer, from the western border zone (Migliara 44.5) and the centre of the former lake (Campo Inferiore), for in tandem dating of this eruption, employing the OxCal code, which yielded a robust age of 3945 ± 10 calBP (1995 ± 10 calBC). To date, this is the only study providing both a terminus post and terminus ante quem of this precision, also demonstrating the advantage of dating distal tephra layers in a clear stratigraphic context over proximal deposits in sequences with major stratigraphic hiatuses. Our new results underscore the importance of the Avellino tephra layer as a precise time marker for studies on the Early Bronze Age of Central Italy.

  10. Effect of antecedent-hydrological conditions on rainfall triggering of debris flows in ash-fall pyroclastic mantled slopes of Campania (southern Italy)

    Napolitano, E.; Fusco, F; Baum, Rex L.; Godt, Jonathan W.; De Vita, P.

    2016-01-01

    Mountainous areas surrounding the Campanian Plain and the Somma-Vesuvius volcano (southern Italy) are among the most risky areas of Italy due to the repeated occurrence of rainfallinduced debris flows along ash-fall pyroclastic soil-mantled slopes. In this geomorphological framework, rainfall patterns, hydrological processes taking place within multi-layered ash-fall pyroclastic deposits and soil antecedent moisture status are the principal factors to be taken into account to assess triggering rainfall conditions and the related hazard. This paper presents the outcomes of an experimental study based on integrated analyses consisting of the reconstruction of physical models of landslides, in situ hydrological monitoring, and hydrological and slope stability modeling, carried out on four representative source areas of debris flows that occurred in May 1998 in the Sarno Mountain Range. The hydrological monitoring was carried out during 2011 using nests of tensiometers and Watermark pressure head sensors and also through a rainfall and air temperature recording station. Time series of measured pressure head were used to calibrate a hydrological numerical model of the pyroclastic soil mantle for 2011, which was re-run for a 12-year period beginning in 2000, given the availability of rainfall and air temperature monitoring data. Such an approach allowed us to reconstruct the regime of pressure head at a daily time scale for a long period, which is representative of about 11 hydrologic years with different meteorological conditions. Based on this simulated time series, average winter and summer hydrological conditions were chosen to carry out hydrological and stability modeling of sample slopes and to identify Intensity- Duration rainfall thresholds by a deterministic approach. Among principal results, the opposing winter and summer antecedent pressure head (soil moisture) conditions were found to exert a significant control on intensity and duration of rainfall

    Full Text Available Although outcropping rarely in Italy, evaporite (gypsum and anhydrite karst has been described in detail since the early 20th century. Gypsum caves are now known from almost all Italian regions, but are mainly localised along the northern border of the Apennine chain (Emilia Romagna and Marche, Calabria, and Sicily, where the major outcrops occur. Recently, important caves have also been discovered in the underground gypsum mines in Piedmont. During the late 80s and 90s several multidisciplinary studies were carried out in many gypsum areas, resulting in a comprehensive overview, promoting further research in these special karst regions. More recent and detailed studies focused on the gypsum areas of Emilia-Romagna and Sicily. Sinkholes related to Permian-Triassic gypsum have been studied in Friuli Venezia Giulia.

Data on mother-child pairs were collected for every syphilis seropositive mother. Maternal syphilis seroprevalence at delivery was 0.17%. 207 infants were born to 203 syphilis seropositive mothers. In 25 newborns it was possible to diagnose congenital syphilis (20/100,000 live births). Maternal risk factors included age syphilis seropositive mothers were foreign born but the risk of an infected newborn was not higher in foreign-born than in Italian seropositive women. The significant factors were lack of antenatal screening and inadequate maternal treatment. Syphilis is a re-emerging infection in Italy. Prevention strategies should include antenatal serological tests for all pregnant women and treatment for infected mothers.

    In Italy the price setting of medicines reimbursed by the National Health Service is regulated at the central level by AIFA, the national regulatory authority. Prices of non reimbursed medicines are indeed freely established, with some limitations, by pharmaceutical companies. To contain pharmaceutical expenditure and rationalise the whole sector the following measures have been introduced in the past years: a threshold to public pharmaceutical expenditure (PPE); a reference price system (RPS) for off-patent medicines; a pay-back mechanism as an alternative to price cut. In 2008 Italy launched a reform of the pharmaceutical expenditure governance system with the aim to introduce stability and promote development and competitiveness in the pharmaceutical sector.

    Tetanus is a serious vaccine-preventable disease that remains a significant health risk in certain occupations. Since 2006, Italy has reported the highest number of cases in Europe. Some professions, such as construction workers, are more exposed to tetanus. To evaluate tetanus immunity status and associated factors in construction workers in Italy. A cross-sectional study of construction workers attending for periodic occupational health surveillance at one site in Italy between September 2011 and January 2013. Serum tetanus antitoxin levels were measured and analysed according to demographic and clinical variables. All 5275 workers attending for health surveillance between September 2011 and January 2013 agreed to participate. Protective tetanus antitoxin levels (>0.1 IU/ml) were found in 4116 workers (78%). Multivariate logistic regression analysis suggested that the following risk factors were significantly associated with inadequate immunization status: older age (age >58 years, odds ratio [OR] 1.78, 95% confidence intervals [CIs] 1.76-1.84), poor education (no formal education: OR 3.74, 95% CI: 3.69-3.78), unskilled work tasks (OR 2.71, 95% CI: 2.67-2.77) and country of origin (Egypt: OR 1.72, 95% CI: 1.67-1.77; Morocco: OR 1.69, 95% CI: 1.62-1.76). In this study, a significant proportion of construction workers in Italy were not adequately immunized against tetanus, as required by Italian law. Occupational health professionals should promote and implement vaccination campaigns, especially among migrant workers, for public health and legal reasons.

    Italy's economic performance between 1945 and 1992 is assessed in a general theoretical framework for productivity growth measurement which enables us to relax the binding assumptions of standard Solow-type neoclassical models. The paper shows that `true productivity' was of minor importance, being outweighted by economies of scale as a source of growth. Productivity gains are large in the `miracle years'; from the late 1960s onwards, productivity levels taper off and cost decreases can be en...

    This report about Southern Italy is part of a larger project, for which the Minstry of Energy has had reports made, examining the possibilities of especially renewable energy sources for the less developed areas of the European Communities: Southern Italy, Portugal, Spain, Greece and Ireland. A number of programmes supported by the EC are mentioned, where money is granted for projects within the energy sector. That is the Valoren programme, which is directed towards the energy sector and the European Fund for Regional Development (EFRU) including integrated Mediterrenean programmes. The report is made in Denmark as desk research with the limitations that makes. Italy is very dependent on imported oil, their production of electricity is primarily based on oil. The energy planning aims at reducing the denpence of imported fuel and spreading the comsumption on several energy sources. Coal is to play a more prominent role in the supply, since it is planned to double the consumption from 1985 to 1995. It was planned that nuclear power was to be more important, but a popular vote said no. The use of internal energy sources will get a higher priority - that is hydroelectric power, geothermal energy, lignite, a small oil and gas production, and renewable energy sources like solar energy, wind energy and biomass. There should be possibilities for Danish export of technology in renewable energy, which is ahead of the Italian. The country itself has great knowhow within the fields of traditional energy technology, geothermal energy, nuclear power and solar energy. The EC has granted large sums of money for the development in Southern Italy, especially the Valoren programme. (SM).

    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.

  1. Culture and the environment in Italy

    Science.gov (United States)

    Alexander, David

    1985-03-01

    This essay evaluates the historical development and current background of human-environment relationships in Italy. The Italian landscape consists of very varied terrain, and periodically suffers from all kinds of natural hazard, especially earthquakes, landslides, floods, and accelerated soil erosion. Some measure of environmental conservation was achieved by the Etruscans and Romans, but the Classical period also marked the beginning of serious lowland waterlogging, malarial infestation, upland soil erosion, and deforestation, which all increased during the Middle Ages. From the Renaissance to the 18th century, there was a diffusion of planned landscapes and carefully managed estates; but by the 20th century, many rural areas could not support growing populations and much land was in need of improvement. Underdevelopment and latifundium agriculture increased the vulnerability to environmental hazards of the Mezzogiorno (Italian South), while the subsequent disappearance of the peasant culture seems not to have led to greatly improved conservation or land management. Poorly farmed or managed landscapes and poorly maintained historic towns have undergone some virtually irreversible degradation, especially with respect to landslides and earthquake damage. Elsewhere in Italy, unchecked urbanization, weak planning laws, and their inadequate enforcement have helped both to reduce environmental quality, by overdevelopment of valued landscapes, and to increase natural disaster vulnerability, by encouraging occupance of natural hazard zones. Although there are signs that the government is beginning to respond to the cumulative effect of environmental degradation, the measures are insufficient to reverse the overall trend toward decadence that characterizes human-land relationships in Italy.

  2. [Consistency and dynamics of immigration in Italy].

    Science.gov (United States)

    Blangiardo, G C; Terzera, L

    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.

  3. Organization of paediatric diabetes units in Italy.

    Science.gov (United States)

    La Loggia, Alfonso

    2005-01-01

    Aim of this work is to give a realistic picture of the medical care situation in Italy and to verify its congruence with ISPAD and SIEDP guidelines and the law. In Italy diabetes is recognized as a disease of great social interest by a state act. Sixteen years after its approval, all of the Italian Regions have received the law n. 115/87 with the different acts. Nearly all regional acts provide for both the institution of specialized centres of paediatric diabetology and their individuation at local level. In Italy diabetological paediatric care is well distributed all over the national territory. Activities are operating in almost every region. Actually a lot of paediatric diabetology activities have no formal recognition and no operating autonomy and sometimes the person in charge of the activity is not a diabetologist paediatrician. In spite of what stated by ISPAD and SIEDP guidelines, this is the real situation. Perhaps in the future a larger presence of scientific societies involved in problems concerning sanitary politics about diabetes, will bring to an appreciable improvement of the quality of care system of paediatric diabetology.

    A geochemical survey was carried out to investigate metal contamination in the Domizio Littoral and Agro Aversano area (Southern Italy) by means of soil, groundwater, human hair and corn samples. Pb isotope ratios were also determined to identify the sources of metals. Specifically, the investigation focused on topsoils (n = 1064), groundwater (n = 26), 25 human hair (n = 24) and corn samples (n = 13). Topsoils have been sampled and analysed in a previous study for 53 elements (including potentially harmful ones), and determined by ICP-MS after dissolving with aqua regia. Groundwater was analysed for 72 elements by ICP-MS and by ICP-ES. Samples of human hair were prepared and analysed for 16 elements by ICP-MS. Dried corn collected at several farms were also analysed for 53 elements by ICP-MS. The isotopic ratios of 206Pb/207Pb and 208Pb/207Pb in selected topsoil (n = 24), groundwater (n = 9), human hair (n = 9) and corn (n = 4) samples were analysed from both eluates and residues to investigate possible anthropogenic contamination and geogenic contributions. All data were processed and mapped by ArcGis software to produce interpolated maps and contamination factor maps of potentially harmful elements, in accordance with Italian Environmental Law (Legislative Decree 152/06). Results show that soil sampling sites are characterized by As, Cd, Co, Cr, Cu, Hg, Pb, Se, and Zn contents exceeding the action limits established for residential land use (RAL) and, in some cases, also the action limits for industrial land use (IAL) as established by Legislative Decree 152/06. A map of contamination factors and a map showing the degrees of contamination indicate that the areas in the municipalities of Acerra, Casoria and Giugliano have been affected by considerable anthropogenic-related pollution. To interpret the isotopic data and roughly estimate proportion of Pb from an anthropogenic source we broadly defined possible natural and anthropogenic Pb end

    2013-06-01

    We simulated the pattern of activity of a strato-volcano by using a cellular automaton model where magma is allowed to ascend to the surface through self-organized crack networks. Magma rises toward the surface by filling connected paths of fractures until the magma's density is less than that of surrounding rocks. If magma enters a region with negative or neutral buoyancy, it cools and solidifies; as a result, the local density profile is modified, and magmatic dikes are formed. We simulated the temporal evolution of high-density pathways of dikes that magma may eventually utilize to reach the surface. We showed that if a shallow neutral-negative buoyancy zone is restored after eruptions, due to, for example, piecemeal or chaotic collapses, a characteristic timescale appears in the inter-event repose time distribution. Such characteristic repose time represents the average time that magma takes to form a high-density pathway through the less dense rock layer, and it may give a hint to predict possible eruptive scenarios. Even if the model includes many simplifying assumptions in the definition of magma-rock interaction, the results obtained from simulations are consistent with the eruptive behavior of the Mt. Somma-Vesuvius volcano for the 1631-1944 period.

    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.

    The occurrence of common respiratory parasites of domestic cats (the metastrongyloid "cat lungworm" Aelurostrongylus abstrusus and the trichuroid Capillaria aerophila) and of neglected respiratory nematodes of felids (Troglostrongylus brevior, Angiostrongylus chabaudi and Oslerus rostratus) was here evaluated in two and three geographical sites of Northern and Central Italy, respectively. In 2014-2015, individual fecal samples of 868 domestic cats were examined microscopically and genetically, and epidemiological data related to parasitic infections were evaluated as possible risk factors by binary logistic regression models. The most common parasite was A. abstrusus in both mono- and poli-specific infections, followed by T. brevior and C. aerophila, while cats scored negative for other parasites. Cats positive for A. abstrusus (1.9-17 % infection rate) and C. aerophila (0.9-4.8 % infection rate) were found in all examined sites, while cats scored positive for T. brevior (1-14.3 % infection rate) in four sites. Also, T. brevior was here found for the first time in a domestic cat from a mountainous area of Northern Italy. The occurrence of lungworms was statistically related to the presence of respiratory signs and more significant in cats with mixed infection by other lungworms and/or intestinal parasites. Cats living in site C of Central Italy resulted statistically more at risk of infection for lungworms than cats living in the other study sites, while animals ageing less than 1 year were at more risk for troglostrongylosis. Finally, the presence of lungworms was more significant in cats with mixed infection by other lungworms and/or intestinal parasites. These results are discussed under epidemiological and clinical points of views.

    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 <0.34 and <0.57Bqkg(-1) respectively, (235)U, (228)Th and (232)Th were always <0.007Bqkg(-1). (137)Cs resulted <0.10Bqkg(-1) in all samples. The committed effective doses due to (210)Po from ingestion of honey for infants, children and adults account for 0.002-5.13% of the natural radiation exposure in 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.

    2016-06-01

    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.

  20. Internal mobility in Italy: A new delay

    Directory of Open Access Journals (Sweden)

    Reynaud Cecilia

    2014-01-01

    Full Text Available From the second half of the 1990s, mobility appears to have changed profoundly from the great migrations of the 1960s, for two main reasons: firstly, the rise in short-range mobility; and secondly, the strong increase in attraction by geographical areas in Central and above all North-eastern Italy. In more recent years, the evolution of internal mobility has changed again, with a further fall coupled with a loss of attractiveness for some Central and Northern areas. The recent evolution of mobility could suggest that the large divide between the North and South is closing. However, this is not entirely the case, as differences in mobility by geographical area continued to remain and in some cases even increased. In fact, this analysis allows us to show how population loss from the South of Italy has actually risen. This study aims to focus on the evolution of the phenomenon in individual geographical areas and the varying levels of migration between the different genders and age classes. While we are clearly not facing a new boom in out-migration from the South, it is true that out-migration is continuing and represents a serious loss of human capital in this area.

    Botulism is a rare but severe neuroparalytic disease caused by botulinum toxins. Because of its high potential impact on public health, botulism is a closely monitored communicable disease in Europe. In Italy, which has one of the highest incidence rates in Europe (0.03 cases per 100,000 population), botulism is monitored through a case-based passive surveillance system: the front-line physician who diagnoses a suspected case must notify the Local Health Units immediately, and the Ministry of Health's office within 12 hours. From 1986 to 2015, 466 confirmed cases of botulism were recorded in Italy (of 1,257 suspected cases). Of these, 421 were food-borne (the most frequently seen form of botulism due to the consumption of improperly home-canned foods), 36 were infant botulism, which accounts for ca 50% of all these types of cases registered in Europe, six were wound-related and three were due to adult intestinal colonisation. This scenario suggests that stronger efforts should be made towards raising public awareness of the risk of food-borne botulism, especially with respect to home-preserved foods, as well as improving the training of front-line medical personnel, to ensure that a quick and accurate diagnosis of botulism can be made.

  2. Vitamin D deficiency in refugees in Italy

    L.G. De Filippis

    2017-09-01

    Full Text Available The objective of the research is to determine 25[OH]D serum levels in refugees in Italy. In the following research we have taken into consideration the results of the monitoring of Vitamin D levels in 46 refugees of the Italian Service for protection of refugees and asylum seekers (SPRAR system. The indicator of overall vitamin D status used was the circulating serum level of 25(OHD. Data was analyzed using Microsoft Excel. In the refugees tested, the mean level of 25(OHD resulted 9.18 ng/mL. The standard deviation was 4.8, with a minimal level of 4.3 and a maximum of 27.4. This figure indicates a clear condition of hypovitaminosis in refugees. While it is general assumption that migratory phenomena may induce the spread of tropical or infectious diseases, widely attested literature demonstrates how chronic pathologies and diseases related to altered lifestyles are the most relevant for Italian case records. Indeed, among the aforementioned diseases, Vitamin D deficiency so far lacks acknowledgement at a national level. Considering the results of lower-than-desirable vitamin D levels found in refugees in Italy, it is necessary to take this parameter into consideration when analyzing individuals who have faced migratory phenomena in order to mitigate the effects of hypovitaminosis D.

    This paper demonstrates the importance of different approaches such as ampelography, historical researches, and molecular analysis to reveal direct parent-child relationship. The aim of this paper was to highlight the degree of relationship to five varieties spread in southern Italy, through ampelographic and molecular characterization: Sangiovese, Mantonico di Bianco, Gaglioppo di Cirò, Mantonicone, and Nerello Mascalese. Molecular characterization was carried out through 52 SSR molecular markers, showing that Sangiovese and Mantonico di Bianco are the parents of Gaglioppo di Cirò, Mantonicone, and Nerello Mascalese. Ampelographic description was performed using the method developed by the Organisation Internationale de la Vigne et du Vin. This analysis identifies three distinct groups: the first brings together Sangiovese and the two offspring Nerello Mascalese and Gaglioppo di Cirò, while Mantonico di Bianco and Mantonicone are positioned at a distance from the first and between them. Using molecular characterization, supported by the ampelographic one, we showed that Gaglioppo di Cirò, Mantonicone, and Nerello Mascalese, three varieties recovered in the southern regions of Italy, such as Calabria and Sicily, originated by the cross between a nationally spread grape variety as Sangiovese and a Calabria autochthonous vine as Mantonico di Bianco.

    Given the severity of outcomes associated with involvement in bullying and the resources spent in an effort to reduce its prevalence, it is important to investigate trends in the bullying's occurrence. The main aim of this study was to identify trends from 2002 to 2010 in prevalence of bullying and victimization among Italian adolescents. The survey reported here is part of the larger population-based cross-sectional (2002, 2006, and 2010) "Health Behaviour in School Aged Children" (HBSC) transnational study. The sample was comprised of 13,174 Italian middle and secondary school students (11- to 15-year-olds; 50.3% girls). Data were collected through a self-report questionnaire. Measures included involvement in bullying as either a perpetrator or a victim. Trends were determined using Gamma statistics. Consistent and robust decreases in the prevalence of bullying between 2002 and 2010 were detected in Italy. During this time frame both frequent and occasional bullying and victimization decreased by half. We measured a strong decrease in involvement in bullying behavior in Italy, in particular after 2006, when the Italian government invested more systematically in the prevention effort on bullying. This is encouraging news for policymakers and practitioners working in the field of bullying prevention. © 2015, American School Health Association.

  5. Naturalizing Alterity: Edward Maturin’s Bianca: A Tale of Erin and Italy and Lady Morgan's Italy

    Donatella Abbate Badin

    2011-08-01

    Full Text Available In the nineteenth century the image of Italy appealed also to Irish Romantic writers. But the way in which they naturalized the Italian alterity is quite ambivalent. On the one hand they filtered their images of the southern country through their relationship with England and thus ended up mirroring stereotypes common to the English-speaking world, and on the other hand they established a special, personal relationship with it shaped by their ideological and cultural differences from the British. This essay tackles the representations of Italy in two texts, namely Edward Maturin’s Bianca: A Tale of Erin and Italy, published in 1852, and in the earlier Italy (1821 by Lady Morgan. Both these works show that at that time there was a certain awareness, in Ireland, of the special historical and political conditions of Italy and of possible similarities with Ireland. Italy, oppressed by foreign domination yet aspiring to freedom, became a yardstick for gauging issues of subjugation, injustice, and national identity and invited sympathy from the citizens of a colonized country. Therefore, Italy was perceived as a mirror in which to reflect the Irish identity torn by aspirations which were hard to confess publicly or even to oneself.

    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.

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

    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.)

    An interdisciplinary approach to the archaeological sites affected by Avellino (3750 yr. B.P.) and Pompei (79 A.D.) plinian eruptions of Somma-Vesuvius provides new data relative to the depositional mechanisms. Large scale stratigraphy and local evi- dences provide new informations about the physical conditions at the emplacement of PDCs and their effects on structures, people and environment. Field evidences indicate that fine grained pyroclastic deposits related to the column collapses propagate up to a distance of about 15 km from the crater and emplaced with conspicuous thickness. In both Avellino and Pompei eruptions, direct evidences from archaeological sites in- dicate that the emplacement in intermediate and distal areas was relatively quite (low mechanical energy). The recognition of thin, continuous, fine grained surge deposits up to a distance of ca. 15 km from the crater suggests that turbulence was important and the PDCs advanced as a relatively thick dilute current, very poorly controlled by the topography. Furthermore, due to the very small sizes, the particles were always transported in suspension, even at very low current velocity, thus avoiding vertical grading to occur. However, due to the very high depositional mass rate, the emplace- ment was very rapid causing buildings and hut, objects, animals and people to be engulfed within the ash deposits thus preserving their original position, as seen at Herculaneum, Oplontis, Pompeii (79 AD) and Nola (3760 bp). The skeletons of hu- man as well animal victims show high temperature effects. In particular, microscopic bones texture of the victims in the sites affected by the 79 A.D are consistent with very high temperatures, which are anomalous in pyroclastic surge clouds.

    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.

    Full Text Available Forty years after transsexual coming out, from the beginning of a physical, cultural and historic transit, what has changed in Italy today? It is certainly the visibility that filled a historical vacuum. It allows us to speak, understand, read the trans experience: for some, as a phenomenon, for others, as category, pathology, gender incongruity. Open questions are several about a complex and varied experience on a socio-cultural contexts at same time complex and varied. One answer is certain: we can no longer talk about transsexualism / transgender in the singular, but rather about plural transsexualism. The Transsexualism is different, various, diversified according to several possible variations that the Post-modern presents us.

    Full Text Available In Italy, Ecotoxicology has found a place with the Legislative Decree n. 152 (May 11, 1999, emanated in fulfilment of the Directives 91/271/CEE "urban waste-water treatment" and 91/676/CEE "protection of waters against pollution caused by nitrates from agricultural sources". This decree in reality goes beyond (actually anticipating the content of the Framework Directive on Water, still under way of elaboration, and charges the Regions with the duty to identify, for all and each water body, the class of quality on the basis of a chemical and biological monitoring and their classification according to the environmental quality objectives. To this aim, for all water bodies (lakes, rivers, groundwater, coastal waters the ecological, chemical, and environmental status must be assessed by measuring specific parameters. This paper briefly summarises the role of biological monitoring in the classification of waters in five different categories, ranking from High to Foul Environmental status.

  16. Adaptively Smoothed Seismicity Earthquake Forecasts for Italy

    2010-01-01

    We present a model for estimating the probabilities of future earthquakes of magnitudes m > 4.95 in Italy. The model, a slightly modified version of the one proposed for California by Helmstetter et al. (2007) and Werner et al. (2010), approximates seismicity by 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 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 historical 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 trustworthy, we used small earthquakes m>2.95 to illuminate active fault structur...

  17. An agreement for applied research in Italy

    CERN Multimedia

    2002-01-01

    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.

    2004-01-01

    The first Italian women described as botanists by their male peers were active during the Risorgimento. They were few in numbers and only one of them, Elisabetta Fiorini, was recognized for her extensive contributions to the field of cryptogams in Italy by being nominated to important Italian scientific academies. No such recognition was ever alloted to the other female botanists who acted as collectors, correspondents and/or patrons to male botanists, had their own garden of exotic plants, or discovered a new species of phanerogams, and occasionally published on the subject. This study will show that a woman could still belong to Italian scientific academies in the nineteenth century, if like Fiorini, she chose to practice science in a way that was considered at par with that of male scientists.

    2012-01-01

    The Health Systems in Transition (HiT) profiles are country-based reports that provide a detailed description of a health system and of policy initiatives in progress or under development. This HiT is one of the first to be written on a subnational level of government and focuses on the Veneto Region of northern Italy. HiTs examine different approaches to the organization, financing and delivery of health services and the role of the main actors in health systems; describe the institutional framework, process, content and implementation of health and health care policies; and highlight challenges and areas that require more in-depth analysis. The Veneto Region is one of Italy's richest regions and the health of its resident population compares favourably with other regions in Italy. Life expectancy for both men and women, now at 79.1 and 85.2 years, respectively, is slightly higher than the national average, while mortality rates are comparable to national ones. The major causes of death are tumours and cardiovascular diseases. Under Italy's National Health Service, the organization and provision of health care is a regional responsibility and regions must provide a nationally defined (with regional input) basic health benefit package to all of their citizens; extra services may be provided if budgets allow. Health care is mainly financed by earmarked central and regional taxes, with regions receiving their allocated share of resources from the National Health Fund. Historically, health budget deficits have been a major problem in most Italian regions, but since the early 2000s the introduction of efficiency measures and tighter procedures on financial management have contributed to a significant decrease in the Veneto Regions health budget deficit.The health system is governed by the Veneto Region government (Giunta) via the Departments of Health and Social Services, which receive technical support from a single General Management Secretariat. Health care is

    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 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." excerpt

  10. 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

    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.

  15. The 2016 Central Italy Earthquake: an Overview

    2016-12-01

    The M6 central Italy earthquake occurred on the seismic backbone of the Italy, just in the middle of the highest hazard belt. The shock hit suddenly during the night of August 24, when people were asleep; no foreshocks occurred before the main event. The earthquake ruptured from 10 km to the surface, and produced a more than 17,000 aftershocks (Oct. 19) spread on a 40x20 km2 area elongated NW-SE. It is geologically very similar to previous recent events of the Apennines. Both the 2009 L'Aquila earthquake to the south and the 1997 Colfiorito to the north, were characterized by the activation of adjacent fault segments. Despite its magnitude and the well known seismic hazard of the region, the earthquake produced extensive damage and 297 fatalities. The town of Amatrice, that paid the highest toll, was classified in zone 1 (the highest) since 1915, but the buildings in this and other villages revealed highly vulnerable. In contrast, in the town of Norcia, that also experienced strong ground shaking, no collapses occurred, most likely due to the retrofitting carried out after an earthquake in 1979. Soon after the quake, the INGV Crisis Unit convened at night in the Rome headquarters, in order to coordinate the activities. The first field teams reached the epicentral area at 7 am with the portable seismic stations installed to monitor the aftershocks; other teams followed to map surface faults, damage, to measure GPS sites, to install instruments for site response studies, and so on. The INGV Crisis Unit includes the Press office and the INGVterremoti team, in order to manage and coordinate the communication towards the Civil Protection Dept. (DPC), the media and the web. Several tens of reports and updates have been delivered in the first month of the sequence to DPC. Also due to the controversial situation arisen from the L'Aquila earthquake and trials, particular attention was given to the communication: continuous and timely information has been released to

    2012-12-01

    In the last decades, a number of Authors highlighted the crucial role of forest fires within Mediterranean ecosystems, with impacts both negative and positive on all biosphere components and with reverberations on different scales. Fire determines the landscape structure and plant composition, but it is also the cause of enormous economic and ecological damages, beside the loss of human life. In Sardinia (Italy), the second largest island of the Mediterranean Basin, forest fires are perceived as one of the main environmental and social problems, and data are showing that the situation is worsening especially within the rural-urban peripheries and the increasing number of very large forest fires. The need for information concerning forest fire regime has been pointed out by several Authors (e.g. Rollins et al., 2002), who also emphasized the importance of understanding the factors (such as weather/climate, socio-economic, and land use) that determine spatial and temporal fire patterns. These would be used not only as a baseline to predict the climate change effect on forest fires, but also as a fire management and mitigation strategy. The main aim of this paper is, thus, to analyze the temporal and spatial patterns of fire occurrence in Sardinia (Italy) during the last three decades (1980-2010). For the analyzed period, fire statistics were provided by the Sardinian Forest Service (CFVA - Corpo Forestale e di Vigilanza Ambientale), while weather data for eight weather stations were obtained from the web site www.tutiempo.it. For each station, daily series of precipitation, mean, maximum and minimum temperature, relative humidity and wind speed were available. The present study firstly analyzed fire statistics (burned area and number of fires) according to the main fire regime characteristics (seasonality, fire return interval, fire incidence, fire size distribution). Then, fire and weather daily values were averaged to obtain monthly, seasonal and annual values, and

    2005-10-01

    Full Text Available In Italy, as in other western countries, trauma is a leading cause of death during the first four decades of life, with almost 18.000 of deaths per year. Since 80s organized systems for trauma care, including a pre-hospital emergency medical system and a network of hospitals designated as Trauma Centres, have been developed in north American countries. Effectiveness of trauma systems has been investigated comparing the post-system to the pre-system trauma care with the method of panel evaluation of preventable death rates and comparison of observed survival with expected probability of survival. In Italy, a pre-hospital emergency medical system has been implemented on a national scale, while a trauma network has not been developed. Nowadays, trauma patients are often admitted to the closest hospital, independently from local resources. The Superior Council of Ministry of Health has presented in 2004 a new trauma system model (SIAT based on the recognition in the field of patients with more serious injuries and the transportation to general hospitals with resources and multidisciplinary teams specialized in trauma care (trauma team. The designation of few trauma team hospitals, one highly specialized Centre (CTS and two area Centres (CTZ every two millions of inhabitants allows each Centre to treat at least 250 severe trauma patients per year to increase experience. Less severe injured patients may be treated in non-trauma team acute care facilities, according to the inclusive system model. The development of trauma team services in some Italian hospitals has demonstrated an increase in survival and a decrease in preventable death rate from 42% to 7,6%. Economic studies of Ministry of Health have established that the implementation of a trauma system model on a national scale with a 25% decrease of preventable trauma deaths and disabilities would save 7500 million of euros of public money. Therefore, in our country the concentration of severely

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

    The steady increase in incidence of chronic respiratory disease (CRD) now constitutes a serious public health problem. CRDs are often underdiagnosed and many patients are not diagnosed until the CRD is too severe to prevent normal daily activities. The prevention of CRDs and reducing their social and individual impacts means modifying environmental and social factors and improving diagnosis and treatment. Prevention of risk factors (tobacco smoke, allergens, occupational agents, indoor/outdoor air pollution) will significantly impact on morbidity and mortality. The Italian Ministry of Health (MoH) has made respiratory disease prevention a top priority and is implementing a comprehensive strategy with policies against tobacco smoking, indoor/outdoor pollution, obesity, and communicable diseases. Presently these actions are not well coordinated. The Global Alliance against Chronic Respiratory Diseases (GARD), set up by the World Health Organization, envisages national bodies; the GARD initiative in Italy, launched 11/6/2009, represents a great opportunity for the MoH. Its main objective is to promote the development of a coordinated CRD program in Italy. Effective prevention implies setting up a health policy with the support of healthcare professionals and citizen associations at national, regional, and district levels. What is required is a true inter-institutional synergy: respiratory diseases prevention cannot and should not be the responsibility of doctors alone, but must involve politicians/policymakers, as well as the media, local institutions, and schools, etc. GARD could be a significant experience and a great opportunity for Italy to share the GARD vision of a world where all people can breathe freely.

    2001-12-01

    Heavy metals pollution, which mainly originates from automobile exhausts and industry, is a serious danger for human health. The source and extension of heavy metals pollution in the top soils has been studied extensively in the past 30 years. The role of the soil processes in accumulating or mobilising metals is very important in environmental science due to the central position of the soil in the hydrological cycle and ecosystem. Concentrations of heavy metals in top soils, collected in green areas and public parks in metropolitan Naples area have been determined to provide information on specific emission sources. In addition to toxic metals, such as Pb, As, Cd, Cr and others, we have investigated the top soils as well for Pt group elements (PGEs), because since 1993 it is mandatory within EC for all new petrol driven motor vehicles to be equipped with Pt/Pd/Rh catalytic converter. In Italy this law has come into effect in 1998, but still is allowed to old vehicles use lead gasoline, though now the big majority of cars is equipped with Pt/Pd/Rh catalytic converters. Emission of abraded fragments of catalytic converters in vehicle exhausts will certainly determine environmental contamination with Pt group elements (PGEs), since many Pt complexes are highly cytotoxic and, in small dose, are strong allergens and potent sensitiser. The metropolitan area of Naples due to intense human activities and vehicles traffic is an interesting area to be monitored in order to check the pollution state of the soils. The geology of the area is prevalently represented by volcanics, erupted from the Upper Pleistocene to Recent by Mt. Somma-Vesuvius on the east and the Campi Flegrei fields on the west. To compile multi-element geochemical maps baseline we have sampled in situ and transported top soil for a total of 200 samples. The survey have been carried at about 200 sites covering an area of about 120 Km2, with a grid of 0.5 x 0.5 km in the highly urbanised area and 1 km x 1 km

    Campi Flegrei is a nested caldera in Italy, at the western edge of the Bay of Naples. Together with Vesuvius and Mt Etna, it is one of the Italian GeoHazard Supersites. The area is characterized by one of the highest volcanic hazard in 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 (~1 m/yr). Minor uplifts of few cm, 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 the present work we consider InSAR time series of the recent activity (2010-2013) detected by COSMO SkyMed satellite. In particular, the time series show a progressive velocity increase of ground deformation during 2012, while it slowed down in 2013 approaching zero. The cumulative displacement from COSMO SkyMed descending orbit (March 2011 - March 2013) show a semicircular pattern centered in Pozzuoli with a maximum LoS (Line of Sight) displacement of 11 cm and maximum velocity 9 cm/yr reached along the coastline. The spatial distribution of the cumulative displacement from COSMO SkyMed ascending orbit show a similar behavior, confirming the bell-shaped pattern of the deformation at least inside the inner rim of the caldera. The cumulative ascending LoS displacement between March 2013 - September 2013 is 1-2 cm, confirming the stall of the unrest after the first few months of 2013 as observed by GPS. Initially, several source geometries are adopted (sphere, spheroid, sill) to model the cumulative deformation between 2011 and 2013. All the sources are located offshore Pozzuoli at a depth of about 2 km. The sphere and spheroid result to dilate at an annual volume variation rate of the order of

    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. Comments concerning the taxonomy of Fissurisepta Seguenza, 1862, Solariella Wood, 1842, Ennucula Iredale, 1931, Thestyleda Iredale, 1929, Ledella Verrill & Bush, 1897, Yoldiella Verrill & Bush, 1897, Bathyspinula Filatova, 1958, Katadesmia Dall, 1908, Austrotindaria Fleming, 1948 and Cadulus Philippi, 1844 are included. 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.

    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.

    Few epidemiologic studies have investigated the potential relation between flavonoids and breast cancer risk. We have applied recently published data on the composition of foods and beverages in terms of six principal classes of flavonoids (i.e., flavanones, flavan-3-ols, flavonols, flavones, anthocyanidines, and isoflavones) on dietary information collected in a large-case control study of breast cancer conducted in Italy between 1991 and 1994. The study included 2,569 women with incident, histologically confirmed breast cancer, and 2,588 hospital controls. Odds ratios (OR) and 95% confidence intervals were estimated by multiple logistic regression models. After allowance for major confounding factors and energy intake, a reduced risk of breast cancer was found for increasing intake of flavones (OR, 0.81, for the highest versus the lowest quintile; P-trend, 0.02), and flavonols (OR, 0.80; P-trend, 0.06). No significant association was found for other flavonoids, including flavanones (OR, 0.95), flavan-3-ols (OR, 0.86), anthocyanidins (OR, 1.09), as well as for isoflavones (OR, 1.05). The findings of this large study of an inverse association between flavones and breast cancer risk confirm the results of a Greek study.

    The operation of Nuclear Power Plants and atmospheric tests of nuclear weapons performed in the past, together with production, transport and reprocessing of nuclear fuel, lead to the release into the environment of a wide range of radioactive nuclides, such as uranium, plutonium, fission and activation products. These nuclides are present in the environment at ultra trace levels. Their detection requires sensitive techniques like AMS (Accelerator Mass Spectrometry). In order to perform isotopic ratio measurements of the longer-lived actinides, e.g., of 236U relative to the primary 238U and various Pu isotopes relative to 239Pu, an upgrade of the CIRCE accelerator (Center for Isotopic Research on Cultural and Environmental Heritage) in Caserta, Italy, is underway. In this paper we report on the results of simulations aiming to define the best ion optics and to understand the origin of possible measurement background. The design of a high resolution TOF- E (Time of Flight-Energy) detector system is described, which will be used to identify the rare isotopes among interfering background signals.

    Knowing the incidence of invasive meningococcal disease (IMD) is essential for planning appropriate vaccination policies. However, IMD may be underestimated because of misdiagnosis or insufficiently sensitive laboratory methods. Using a national molecular surveillance register, we assessed the number of cases misdiagnosed and diagnoses obtained postmortem with real-time PCR (rPCR), and we compared sensitivity of rPCR versus culture-based testing. A total of 222 IMD cases were identified: 11 (42%) of 26 fatal cases had been misdiagnosed or undiagnosed and were reclassified as IMD after rPCR showed meningococcal DNA in all available specimens taken postmortem. Of the samples tested with both rPCR and culture, 58% were diagnosed by using rPCR alone. The underestimation factor associated with the use of culture alone was 3.28. In countries such as Italy, where rPCR is in limited use, IMD incidence may be largely underestimated; thus, assessments of benefits of meningococcal vaccination may be prone to error.

    Objective: We provide a nationwide population study of patients with congenital muscular dystrophy in Italy. Methods: Cases were ascertained from the databases in all the tertiary referral centers for pediatric neuromuscular disorders and from all the genetic diagnostic centers in which diagnostic tests for these forms are performed. Results: The study includes 336 patients with a point prevalence of 0.563 per 100,000. Mutations were identified in 220 of the 336 (65.5%). The cohort was subdivided into diagnostic categories based on the most recent classifications on congenital muscular dystrophies. The most common forms were those with α-dystroglycan glycosylation deficiency (40.18%) followed by those with laminin α2 deficiency (24.11%) and collagen VI deficiency (20.24%). The forms of congenital muscular dystrophy related to mutations in SEPN1 and LMNA were less frequent (6.25% and 5.95%, respectively). Conclusions: Our study provides for the first time comprehensive epidemiologic information and point prevalence figures for each of the major diagnostic categories on a large cohort of congenital muscular dystrophies. The study also reflects the diagnostic progress in this field with an accurate classification of the cases according to the most recent gene discoveries. PMID:25653289

    The Monfalcone area, northeastern Italy, a small industrial district with large shipyards, shows a high incidence of asbestos-related mesothelioma. In order to reconstruct some features of the Monfalcone shipbuilding activity during World War II and its health effects, the shipyard roll were examined, and people hired in 1942 were identified. The list of 2,776 persons hired in 1942 was coupled with the Pathological Anatomy Units archives of the Monfalcone and the Trieste Hospitals. Eighteen of the above persons had been diagnosed with pleural mesothelioma in the period 1981-2005. Eight patients had their first exposure in 1942, and the others had histories of previous exposures. Of 557 persons aged 14-15 years in 1942, six had a diagnosis of pleural mesothelioma. Necropsy findings were available in 14 cases. The burdens of lung asbestos bodies, isolated in 11 cases, showed wide variation (from 150 to 600,000 bodies per gram of dried tissue). While probably underestimated, the present data indicate a high incidence of mesothelioma among the shipyard workers of Monfalcone.

    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.

    Over the last decades, the globalisation and important geopolitical changes have widened the spatial boundaries of international migrations which have reached a so global scope today that they influence the economic, political and social trend of countries of origin, transit and destination. According to the UN, the international labour mobility involved more than 200 million people in 2010, that is approximately 10% of the world's total population. In Italy, in the beginning of 2010 foreign residents amounted to 4.2 million, that is to say, 7% of the total population (ISTAT, 2011). Host countries have been forced to implement a series of policies aimed at combating illegal immigration and employment of foreign people. Special attention must be given to the issue of migrant workers who have become increasingly important actors in the social and productive sectors and, as a consequence, the need for preventive and protective measures taking into consideration the specific work-related hazards is growing more and more urgent. With this respect, the regulatory framework for occupational health and safety now contains explicit references to migrant workers as provided in the Leg. Decree 81/08 with subsequent integrations and modifications. First of all, the issue of occupational health and safety for migrant workers must take into account of the linguistic, social and cultural problems of the different ethnical groups that are present in our country.

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

  14. 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

    Full Text Available Vesuvius, dominating the densely-populated Neapolitan area, is one of the most dangerous volcanoes in the World. Its destructive power derives from energetic subplinian and plinian eruptions, such as the one which occurred in 79 A.D. Generally such large-scale events follow a long period of quiescence; a behaviour interpreted as the gradual build-up of magma volumes between periods of major activity. After the 1631 subplinian eruption until the last 1944 A.D. eruption, it experienced an almost continuous and less energetic explosive/effusive activity. The erupted magmas are characterized by undersaturated potassic to ultrapotassic nature, and compositional and Sr-isotopic variability. Furthermore geobarometric studies indicate two different crystallization depths located at 4 and >11 km, respectively. According to most of the recent literature, the eruptions were triggered by the injection in a shallower magma chamber, of isotopically distinct magma batches derived from heterogeneous mantle source(s and/or contamination processes occurred within the deep reservoir. In our review of petrochemical data, we consider the period between the 3550 years BP plinian eruption and the 472 A.D. sub-plinian eruption, which includes 79 A.D. event, and the most recent period of activity which started in 1631 A.D. and lasted up to the 1944 A.D. eruption, characterized by a near continuous effusive/explosive activity. For both periods we identify a correlation between Sr-isotopical features of magmas and their crystallization depth. In particular, we show that pyroxenes have Sr-isotopic ratios lower than 0.7074 and an equilibrium crystallization depth of 22-11 km. Moreover feldspars have higher 87Sr/86Sr values (0.7075-7 and an equilibrium crystallization depth of about 4 km. Therefore the most radiogenic magmas did not derive from a deeper reservoir but their higher Sr-isotopic ratios have been acquired at a shallower depth likely by crustal contamination

  16. Second-hand smoke in Italy.

    2015-12-01

    Second-hand smoke (SHS) has been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) [IARC, 2004]. Of the 5.7 million deaths attributable each year to tobacco smoking, more than 600,000 (i.e., around 1% of all deaths worldwide) refer to subjects who never smoked and that prematurely die due to their lifetime exposure to SHS [WHO, 2012]. Italy has been one of the pioneering countries - and the first large country worldwide - to enact a comprehensive smoke-free legislation in 2005. The law, introduced in order to reduce SHS exposure, banned smoking in indoor public places, including restaurants and bars, and in all workplaces [Gallus et al., 2006]. This legislation has had an undisputed success from a public health perspective: it was widely supported and strongly observed, restaurant and bar owners did not experience any dreaded decline in their business, and tobacco smoking (and its detrimental health effects) substantially decreased [Gallus et al., 2006; Gorini et al., 2007]. More importantly, the regulation has been effective in dramatically reducing SHS exposure [Gorini et al., 2007; Martinez-Sanchez et al., 2012]. Most high- income countries followed Italy in the adoption of similar comprehensive smoking ban legislations over the last decade [IARC, 2009]. These regulations and the information campaigns conducted for their enforcement had also the effect to increase the social unacceptability of SHS and consequently the adoption of voluntary home smoking bans [Ferketich et al., 2014; Martinez-Sanchez et al., 2014]. This notwithstanding, in 2010 specific Italian subpopulations were still frequently exposed to SHS, both in public and private places. In particular, 54% of the young (i.e., age 15-24 years) were still exposed to SHS in any settings, 27% in private houses, and 33% in private cars [Martinez-Sanchez et al., 2012]. The relatively high SHS exposure in private cars is of

    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.

  18. Adaptively smoothed seismicity earthquake forecasts for Italy

    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.

    Purpose Usher syndrome is an autosomal recessive disorder characterized by hearing and vision loss. Usher syndrome is divided into three clinical subclasses (type 1, type 2, and type 3), which differ in terms of the severity and progression of hearing loss and the presence or absence of vestibular symptoms. Usher syndrome is defined by significant genetic heterogeneity, with at least 12 distinct loci described and 9 genes identified. This study aims to provide a molecular epidemiology report of Usher syndrome in Italy. Methods Molecular data have been obtained on 75 unrelated Italian patients using the most up-to date technology available for the screening of Usher syndrome gene mutations, i.e., the genotyping microarray developed by Asper Biotech (Tartu, Estonia), which simultaneously investigates 612 different marker positions using the well established arrayed primer extension methodology (APEX). Results Using this method, we found that 12% of cases (9 out of 75) harbored homozygous or compound heterozygous mutations in the gene positions analyzed, whereas 20% (15 out of 75) of the patients were characterized by the presence of only one mutated allele based on the positions analyzed. One patient was found to be compound heterozygous for mutations in two different genes and this represents an example of possible digenic inheritance in Usher syndrome. A total of 66.6% of cases (50 out of 75) were found to be completely negative for the presence of Usher syndrome gene mutations in the detected positions. Mutations detected by the array were confirmed by direct sequencing. Conclusions These findings highlight the efficacy of the APEX-based genotyping approach in the molecular assessment of Usher patients, suggesting the presence of alleles not yet identified and/or the involvement of additional putative genes that may account for the pathogenesis of Usher syndrome.

    Usher syndrome is an autosomal recessive disorder characterized by hearing and vision loss. Usher syndrome is divided into three clinical subclasses (type 1, type 2, and type 3), which differ in terms of the severity and progression of hearing loss and the presence or absence of vestibular symptoms. Usher syndrome is defined by significant genetic heterogeneity, with at least 12 distinct loci described and 9 genes identified. This study aims to provide a molecular epidemiology report of Usher syndrome in Italy. Molecular data have been obtained on 75 unrelated Italian patients using the most up-to date technology available for the screening of Usher syndrome gene mutations, i.e., the genotyping microarray developed by Asper Biotech (Tartu, Estonia), which simultaneously investigates 612 different marker positions using the well established arrayed primer extension methodology (APEX). Using this method, we found that 12% of cases (9 out of 75) harbored homozygous or compound heterozygous mutations in the gene positions analyzed, whereas 20% (15 out of 75) of the patients were characterized by the presence of only one mutated allele based on the positions analyzed. One patient was found to be compound heterozygous for mutations in two different genes and this represents an example of possible digenic inheritance in Usher syndrome. A total of 66.6% of cases (50 out of 75) were found to be completely negative for the presence of Usher syndrome gene mutations in the detected positions. Mutations detected by the array were confirmed by direct sequencing. These findings highlight the efficacy of the APEX-based genotyping approach in the molecular assessment of Usher patients, suggesting the presence of alleles not yet identified and/or the involvement of additional putative genes that may account for the pathogenesis of Usher syndrome.

  1. Global change and river flow in Italy

    2017-08-01

    The hydrological data of 23 flow gauges, evenly distributed across the Italian territory and covering almost 40% of it, have been analyzed in order to verify the occurrence of temporal trends and their rates of change. A total of 102 time series diagrams of the parameters considered, i.e. precipitation, runoff, maximum discharge, discharge exceed 10 days a year, were obtained. The results indicate that all the parameters considered show a decreasing trend. Also the comparison of bankfull discharge calculated for three periods, prior to 1951, 1951-1980 and 1981-2007, indicate a substantial decrease. The general decrease in river flow is accounted for in terms of global change (namely precipitation, land use change and water consumption increase). In the aim to summarize the pattern of change of the parameters considered, the data have been standardized and mean time series of Z score for a few representative rivers have been obtained. All these results depict for Italy a framework of substantial decrease of water resources (average precipitation and runoff decreasing rates are - 2.11 and - 2.65 mmyr- 1, respectively) and sediment transport capacity with evident consequences on the river ecosystems and beach stability. The countertrending behavior of medium to high discharge of the Po River are analyzed and explained in terms of temperature increase. In order to investigate the role of the upstream catchment area in determining the variability of a few of the parameters considered in this study, simple regression analyses have been performed which demonstrate a high degree of accuracy in predicting specific discharges also for rivers without flow records or insufficient flow data.

  2. Moral Foundations and Voting Intention in Italy.

    Milesi, Patrizia

    2017-11-01

    Based on the view of morality proposed by the Moral Foundations Theory, this paper investigates whether voting intention is associated with moral foundation endorsement in not perfectly bipolar electoral contexts. Three studies carried out in Italy from 2010 to 2013, showed that controlling for ideological orientation, moral foundation endorsement is associated with voting intention. In Study 1 and 3, in fictitious and real national elections, intention to vote for right-wing political groups rather than for left-wing rivals was associated with Sanctity, confirming previous results obtained in the U.S. Furthermore, as a function of the specific competing political groups in each of the examined contexts other moral foundations predicted voting intention. In Study 1, Care and Authority predicted voting intention for the major political groups rather than for an autonomist party that aimed at decreasing central government's fiscal power in favor of fiscal regional autonomy. In Study 3, Loyalty predicted the intention to vote for the major parliamentarian parties rather than for a movement that aimed at capturing disaffection towards traditional politics. In Study 2, at real regional elections, Loyalty predicted voting intention for the incumbent right-wing governor rather than for the challengers and Fairness predicted voting intention for left-wing extra-parliamentarian political groups rather than for the major left-wing party. Thus multiple moral concerns can be associated with voting intention. In fragmented and unstable electoral contexts, at each election the context of the competing political groups may elicit specific moral concerns that can contribute to affect voting intention beyond ideological orientation.

    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

  4. A socioeconomic profile of vulnerable land to desertification in Italy.

    2014-01-01

    Climate changes, soil vulnerability, loss in biodiversity, and growing human pressure are threatening Mediterranean-type ecosystems which are increasingly considered as a desertification hotspot. In this region, land vulnerability to desertification strongly depends on the interplay between natural and anthropogenic factors. The present study proposes a multivariate exploratory analysis of the relationship between the spatial distribution of land vulnerability to desertification and the socioeconomic contexts found in three geographical divisions of Italy (north, center and south) based on statistical indicators. A total of 111 indicators describing different themes (demography, human settlements, labor market and human capital, rural development, income and wealth) were used to discriminate vulnerable from non-vulnerable areas. The resulting socioeconomic profile of vulnerable areas in northern and southern Italy diverged significantly, the importance of demographic and economic indicators being higher in southern Italy than in northern Italy. On the contrary, human settlement indicators were found more important to discriminate vulnerable and non-vulnerable areas in northern Italy, suggesting a role for peri-urbanization in shaping the future vulnerable areas. An in-depth knowledge of the socioeconomic characteristics of vulnerable land may contribute to scenarios' modeling and the development of more effective policies to combat desertification. © 2013 Elsevier B.V.

    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.

    Full Text Available This article deals with the history of the neo-Calvinist movement in France and Italy. The efforts of the Dutch Reformational movement to communicate with French (mainly reformed Christians are highlighted. A brief overview of the achievements of the few French scholars involved in this development is sketched and their publications are mentioned, together with a few conferences and organisations. Neo-Calvinism reached Italy as well, via the input of French lecturers and publications. The few developments of neo-Calvinism in Italy are recorded as well. Also, the gradual drift towards vantilian and reconstructionist positions (in both countries is detected and discussed. An evaluation of these developments is provided, together with a few final considerations and questions which should help learning lessons from the past and preparing better strategies for the future.

    Brucellosis is a common and chronic disease of cattle and other bovids that often causes reproductive disorders. Natural infection in cattle is caused by Brucella abortus and transmission typically occurs during abortions, calving, or nursing. Brucellosis is also a major zoonotic disease due to contamination of dairy products or contact with the tissues of infected animals. Brucellosis has been eradicated from most of the developed world in the last 40 years but persists in many regions-the disease remains prevalent in portions of Africa, the Middle East, Asia, and Central and South America, as well as in the Mediterranean basin. In Italy, B. abortus has persisted in southern regions in both cattle and water buffalo. Previous attempts at analyzing the phylogenetics of B. abortus in Italy have been challenging due to limited genetic variability and unresolved global population genetic structure of this pathogen. We conducted genome-wide phylogenetic analyses on 11 representative strains of B. abortus from Italy, and compared these sequences to a worldwide collection of publically available genomes. Italian isolates belong to three clades that are basal to the main and global B. abortus lineage. Using six SNP-based assays designed to identify substructure within the Italian clades, we surveyed a collection of 261 isolates and found that one clade predominates throughout endemic districts in the country, while the other two clades are more geographically restricted to portions of southern Italy. Although related strains exist worldwide, B. abortus isolates from Italy are substantially different than those found in much of the rest of Europe and North America, and are more closely related to strains from the Middle East and Asia. Our assays targeting genetic substructure within Italy allowed us to identify the major lineages quickly and inexpensively, without having to generate whole genome sequences for a large isolate collection. These findings highlight the

  9. Market Brief : The insulation and waterproofing products market in Italy

    2001-10-01

    The use of thermal insulation in buildings in Italy is among the lowest in Western Europe. Soon, operational regulations will be in place, creating considerable opportunity for Canadian companies interested in gaining access to the Italian market through materials that provide better insulation and waterproofing for existing buildings. Approximately three fifths of the Italian insulation demand is for foamed plastics. Areas with strong commercial potential include products such as lightweight acoustic insulation materials, polymer bitumen membranes, fire-retardant foam plastic insulation, water-based waterproofing products as well as advanced waterproofing products. In 1999, the demand for insulation in Italy reached 352 million square metres of R-1 value. Currently, the most active exporters to Italy are neighbouring European countries. Italy's leading domestic insulation manufacturers are Saint-Gobin-Isover Italia, Dow, BASF and Sirap Gema. Italian industry experts recognize that in addition to heat savings, thermal insulation in buildings can contribute to reducing carbon dioxide emissions through energy efficiency. Demand for insulation products in Italy is expected to grow by 2.6 per cent per year through 2004. Demand is expected to reach $814 million in 2004. Approximately 3500 apartment buildings are in need of major renovations due to their age and because of poor construction systems used in the 1960s. Canadian imports of insulation and waterproofing products to Europe are recognized for their high quality and innovation. However, transportation costs are generally prohibitive. In January 2001, Canada Mortgage and Housing Corporation signed a Memorandum of Understanding with the Italian government to promote and extend exchange of information on building standards and practices, increasing Canada-Italy collaboration within the building sector. 1 tab.

    Full Text Available Lady Morgan (née Sydney Owenson was a professional Irish travellerand travel-writer, who spent over a year on the peninsula. The travelogueItaly (1821 she was commissioned to write on the basis of the reputationshe had acquired as a novelist (e.g. The Wild Irish Girl, 1806 anda socio-political writer (France, 1817, left a mark on Italy and on theunderstanding of Italy in Great Britain. Her writings, in fact, helpeddisseminate the ideal of a unified Italy and influence British and Irishpublic opinion in favour of Italy’s aspirations to cast off foreign or domesticautocratic rule. Moreover, she used her travelogue to serve thecause of Ireland disguising a patriotic message about her home countryunder her many sallies about nationalism and the right to self-determinationconcerning Italy. The political impact of her book, unusualfor a travel account written by a woman, was enhanced by Morgan’sradical ideology, the gender bias of her observations and her originalmethods. The present article purposes to examine Morgan’s double,feminine and masculine, approach of mixing solid documentation withapparently frivolous notes originating in the feminine domain of societynews, commentary on the domestic scene and emotional reporting onsocial and historical events. Distrusting male-authored official history,Morgan gave a central place in her work to the informal sources fromwhich she gathered her insights about Italy. Analysing how she came toobtain the contemporary input for elaborating her ideas will be the aimof this chapter which will dwell on the more worldly aspects of Morgan’ssojourn in the peninsula focussing on the company she kept, theactivities she partook of, the events of a domestic nature she witnessed.

    Entomological, veterinary, and human surveillance systems for West Nile virus (WNV) infection have been implemented in Italy since the first detection of the virus in 1998. These surveillance activities documented a progressive increase of WNV activity and spread in different regions and the emergence of new WNV lineages and strains. Italy is a paradigmatic example of the complex epidemiology of WNV in Europe, where sporadic cases of WNV infection, clusters, and small outbreaks have been reported in several regions. In addition, different strains of both WNV lineage 1 and lineage 2 have been identified, even co-circulating in the same area. PMID:24084676

    Full Text Available This paper investigates how family size affects children's human capital, comparing Italy and France. We tested the dilution effect in these countries, starting with the assumption that the higher the number of siblings, the fewer parental resources are available for each child, and the lower the probability that each child will successfully pursue his/her educational career. We find a negative correlation between the number of siblings and human capital. However, when the analysis is developed with a causal approach, the strength of the dilution effect weakens in Italy and disappears in France.

    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."

    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. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

    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.

    We conducted a hospital-based case-control study of 153 patients who had been recently diagnosed with myocardial infarction; there were 157 hospital controls. All subjects were 35-70-y-old males who lived in the province of Torino (northern Italy). These individuals were nonsmokers or had quit smoking for at least 6 mo. A protective role of migration from southern Italy was found (age-adjusted odds ratio for northern versus southern origin = 1.82, 95% confidence interval = 1.0, 3.3). Although fat consumption differed greatly between those born in northern Italy and those in southern Italy (i.e., the former used mainly butter and the latter used mainly olive oil during their early lives), it did not explain the migration effect. A family history of myocardial infarction increased the risk of a myocardial infarction (odds ratio = 2.4, 95% confidence interval = 1.1, 4.9). Moderate coffee consumption also increased the risk and was not explained by the known coronary risk factors. Relative risks were up to 4 among both nonsmokers and exsmokers who drank more than 4 cups of coffee each day. We controlled for coffee drinking and found that the association with southern origin appeared strengthened.

    Human cases of gastric anisakiasis caused by the zoonotic parasite Anisakis pegreffii are increasing in Italy. The disease is caused by ingestion of larval nematodes in lightly cooked or raw seafood. Because symptoms are vague and serodiagnosis is difficult, the disease is often misdiagnosed and cases are understimated. PMID:23621984

    The large physiographic variability and the abundance of landslide and rainfall data make Italy an ideal site to investigate variations in the rainfall conditions that can result in rainfall-induced landslides. We used landslide information obtained from multiple sources and rainfall data captured by 2228 rain gauges to build a catalogue of 2309 rainfall events with - mostly shallow - landslides in Italy between January 1996 and February 2014. For each rainfall event with landslides, we reconstructed the rainfall history that presumably caused the slope failure, and we determined the corresponding rainfall duration D (in hours) and cumulated event rainfall E (in mm). Adopting a power law threshold model, we determined cumulated event rainfall-rainfall duration (ED) thresholds, at 5% exceedance probability, and their uncertainty. We defined a new national threshold for Italy, and 26 regional thresholds for environmental subdivisions based on topography, lithology, land-use, land cover, climate, and meteorology, and we used the thresholds to study the variations of the rainfall conditions that can result in landslides in different environments, in Italy. We found that the national and the environmental thresholds cover a small part of the possible DE domain. The finding supports the use of empirical rainfall thresholds for landslide forecasting in Italy, but poses an empirical limitation to the possibility of defining thresholds for small geographical areas. We observed differences between some of the thresholds. With increasing mean annual precipitation (MAP), the thresholds become higher and steeper, indicating that more rainfall is needed to trigger landslides where the MAP is high than where it is low. This suggests that the landscape adjusts to the regional meteorological conditions. We also observed that the thresholds are higher for stronger rocks, and that forested areas require more rainfall than agricultural areas to initiate landslides. Finally, we

    Full Text Available Abstract Background While Italy has implemented some tobacco control policies over the last few decades, which resulted in a decreased smoking prevalence, there is still considerable scope to strengthen tobacco control policies consistent with the World Health Organization (WHO policy guidelines. The present study aims to evaluate the effect of past and project the effect of future tobacco control policies on smoking prevalence and associated premature mortality in Italy. Methods To assess, individually and in combination, the effect of seven types of policies, we used the SimSmoke simulation model of tobacco control policy. The model uses population, smoking rates and tobacco control policy data for Italy. Results Significant reductions of smoking prevalence and premature mortality can be achieved through tobacco price increases, high intensity media campaigns, comprehensive cessation treatment program, strong health warnings, stricter smoke-free air regulations and advertising bans, and youth access laws. With a comprehensive approach, the smoking prevalence can be decreased by as much as 12% soon after the policies are in place, increasing to a 30% reduction in the next twenty years and a 34% reduction by 30 years in 2040. Without effective tobacco control policies, a total of almost 300 thousand lives will be prematurely lost due to smoking by the year 2040. Conclusion Besides presenting the benefits of a comprehensive tobacco control strategy, the model helps identify information gaps in surveillance and evaluation schemes that will promote the effectiveness of future tobacco control policy in Italy.

    In the framework of the URGE (Urban Geochemistry) project aiming at depicting the environmental conditions of several cities in Europe, the north-eastern sector of the Naples metropolitan area (Italy), namely the Acerra-Pomigliano-Marigliano area (with ~160.000 inhabitants), has undergone a geochemical characterization based on topsoil sampling (145 samples over an area of 90 sqkm). The conurbation includes 6 municipalities (Acerra, Pomigliano D'Arco, Castello di Cisterna, Brusciano, Mariglianella and Marigliano) and considering the total extension of the urbanized areas (18-20 sqkm) the average population density could be corrected to 6-7000 inhabitants/sqkm. Soils of the area are mostly originated by the pedogenenesis of the original pyroclastics produced by the Mt. Somma-Vesuvius volcano on the south-western side of the study area. The area has been selected because of both the presence of an historical industrial settlement on it (mainly devoted to plastic materials and synthetic fibers production) and of an incinerator which came into operation in March 2009. The main objective of the study was 1) to define the local geochemical baselines both for 53 elements (among which the toxic ones) and for some organic compounds, including PAHs, PCBs and OCPs and 2) to assess the environmental risk generated by polluted soils. Furthermore, the study aimed at supporting epidemiological researches and at establishing a record of the environmental status quo ante to evaluate in the future the impact of the incinerator on life quality and on health of local population. Obtained results showed that most of the urbanized areas of the Acerra-Pomigliano-Marigliano conurbations are characterized by concentrations of Pb, Zn and V exceeding the intervention limits established by the Italian Environmental law (D.Lgs. 152/2006). Agricultural soils, in the surroundings of the urbanized areas, are enriched in Cu, Co, Cd, Be and Ni, and the probable presence of illegal waste disposals

  10. A preliminary attempt to determine the landslide hazard in Italy

    2013-04-01

    Determining landslide hazard at the national scale remains a difficult task. However, such a complex task needs to be accomplished to mitigate the landslide consequences, including loss of lives and economic and environmental damages. For administrative purposes, the Italian territory (303,000 km sq.) is subdivided in 20 regions that cover a large variety of natural environments, most of which are subject to landslide hazards. To determine landslide hazard in such a complex and diversified territory, the many natural and anthropogenic variables, and their variations, must be considered. In Italy, the Italian national Civil Protection Department (DPC), an office of the Prime Minister, is in charge of managing natural and human-made hazards, and the associated risk. For landslide (and flood) hazards, the DPC has subdivided the Italian territory into 134 "alert zones" (AZ), decided based on administrative and hydrological criteria. Here, we describe the results of a preliminary effort made by our research group - in the framework of a larger effort to forecast landslide hazard and risk in Italy - to describe landslide hazard in each AZ. For the purpose, we summarized in a specifically designed form the geographical, morphological, geological and landslide information available for each AZ. The form also contains general information on past landslide events and on the vulnerability to landslides of the AZ. We obtained the morphological information from the SRTM DEM with a grid resolution of 90 m × 90 m, and the geological and lithological information from the Geological Map of Italy, at the 1:500,000 scale, published by the Italian Istituto Superiore per la Protezione e la Ricerca Ambientale (ISPRA). We used the morphological (terrain elevation and terrain gradient) and the lithological information to subdivide the Italian territory in three main morphological domains (plains, hills and mountains), and we computed the proportion of the three domains in each AZ.

    The stratigraphic sequence of Scafati, about 3 km east of ancient Pompeii, is presented consisting of a multilayered sequence of repeated volcanic deposition and pedogenesis that was caused by several phases of volcanic activity and volcanic quiescence of Somma-Vesuvius, at least, the last 20,000 years. Micromorphological analysis were carried out at the soil material and selected volcanic deposits to establish a chronological succession of different phases of volcanic deposition, pedogenetic transformation but also to highlight the anthropogenic influence. The micromorphological analysis testified furrow irrigation and soil cultivation in the medieval stratigraphy and allowed the identification of very significant antropogenic features in the Bronze Age/Iron Age paleosol, i.e. complex depositional crusts and dusty clay coatings and hypocoatings, which are often used as an indicator for tillage activity. In contrast to the clear macroscopic and chemical evidence of ancient soil cultivation, the Roman paleosol did not exhibit distinct micromorphological signs of soil cultivation.

    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.

    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.

    Among air pollutants, ozone is the most important stressor to vegetation, which undergoes damage and biomass reduction after penetration of ozone molecules into the leaf tissues through the stomata. Stomatal ozone fluxes are considered the governing factor needed to assess risk to plant health due to ozone. Although this parameter may be calculated by modeling, direct measurements are scarce. Moreover, southern European situations, especially regarding Italy, require special attention due to the decoupling between ozone concentrations and fluxes. This work reviews ozone flux measurements made during the last 15 years through Italy. - The dependence of ozone fluxes on environmental factors such as water supply is stronger than the dependence on the surface covering species.

    Toxoplasmosis, an important zoonosis, can be transmitted by eating meat or drinking milk of animals infected with Toxoplasma gondii. Samples were collected from 238 donkeys in the year 2010 in Italy, which included 207 females and 31 males of five breeds and crossbreeds with the average age 9 years (1 month-24 years). Sera were tested for T. gondii antibodies using a latex agglutination test and the indirect fluorescent antibody test; 5 and 8% seropositivity were recorded, respectively. We found significant correlation between the presence of T. gondii antibodies and sex, age, grazing and presence of cats on the farms and their access to donkey feed. This is the first detection of T. gondii antibodies in donkeys in Italy.

    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.

    This paper focuses on the motives and long-term effects of the momentous decision to build a world-class biomedical research laboratory, the International Center for Chemical Microbiology, at the Istituto Superiore di Sanità in Rome, rather than develop domestic production of penicillin to meet the needs of a destitute postwar Italy. An institutionalist approach will provide a richer vision of the intersections of scientific and national political history in postwar Italy and the Cold War. The Center failed in its modernising mission due to an insular mentality producing an 'enclosure effect' against the State, the healthcare system and the pharmaceutical industry. The absence of a scientific base together with an economic policy of 'liberal protectionism' that placed premiums on import tariffs and the licensing of foreign products explains the path dependency of the pharmaceutical industry during the postwar years and its demise in the 1960s.

    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 Maternal mortality and morbidity related to perinatal events are increasingly rare in advanced countries. Maternal death events represent an indicator of the overall health and development conditions of a country. In Italy, similarly to other industrialized countries, the maternal mortality ratio has been approximately 3 cases per 100,000 live births. However, recently, it has been measured as 11 cases per 100,000 live births, with a severe maternal morbidity rate of 2‰. The neonatal mortality rate has been, instead, constant at approximately 2.4‰ live births, with a rate of childhood cerebral palsy of 2‰. The incidence of caesarean section in Italy is 38% on average. It is the highest in Europe, with significant regional differences. The higher incidence is observed in the birth centres of South-Italy and in those with a fewer number of deliveries. The whole “birth pathway” should be organized and planned on a regional basis according to the models of organizational network of perinatal care by Hub & Spoke and according to the principles ratified by the GL (guidelines on the Charter of Services N. 2/95, such as: equity, accountability, participation, quality and safety of care, humanization. However, an obstacle to the implementation of this program is represented by the exponential and manufactured increase of medico-legal controversies (+ 250% of complaints over the last 15 years with over 98% of acquittal in favour of the doctors for the Supreme Court. This issue discredits the entire medical profession and is responsible for the recourse to defensive medicine which drains each year 10bn euros. Therefore, a joined action among the legislature, the professional associations and the civil society is needed. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa

    2014-01-01

    Full Text Available During the last decade, migration flows have greatly affected the Italian economy and demography. The trend is growing, not only because of the ideal geographic position for transit, but also due to the Italian economic structure, and business interest: Cheap labour is greatly in demand among employers. The increasing number of migrants has created a certain imbalance in different spheres of life and society. The middle-aged population in Italy is ever growing, thus migrants play an important role in filling the workforce depletion as well as flooding the labor market. The effects of migration cannot be viewed as either positive or negative. In the recent decade, Italy has been pursuing a tight budgetary policy regarding its obligations under the Economic and Monetary Union. At the same time, the government realizes the necessity of radical restructuring of the national market, both taking measures to encourage entry of fully qualified migrants and by restricting illigal or low-skilled immigrants. The state faces a number of problems, such as job placement and assimilation of migrants into society. Some of the objectives are to provide them with the employment, cultivate European values and teach them Italian. While migrants are relevant, the shadow sector of the economy - sheltering iltygals - is growing. The economy and the budget suffer, and the external debt is growing. The article presents the data on the demographic situation in Italy. It analyzes the correlation between the migrants and the indigenous people in the labor market. Special attention is focused on socioeconomic consequences of immigration in Italy. International experience in general and Italian in particular are highly important to improving the migration policy, developing systems of internal and external control of the migration processes, illegal migration control, and a quota system; the government even takes note of fertility among migrants.

    2000-01-01

    The evaluation of the external costs caused by the impact of air pollution on human health is fraught with theoretical and empirical difficulties. Many issues are still unsatisfactorily dealt with. Due to the lack of theoretical consensus and good empirical data, the existing estimates on external costs of air pollution in Italy show a very large variability. This sends a noisy signal to the policy makers who ought to develop fiscal policies. In the paper we report on a new estimate we perfor...

    Full Text Available Based on a qualitative content analysis of a small corpus of newspaper articles, the paper aims to identify the representations of Romanian migrants in the Romanian media from Italy by exploring the portrayals of the main characters and the narratives used to support these portrayals. Arguing that there are important differences between the narrative styles employed for depicting different types of characters, I seek to discuss the implications these differences may have on the conveyed message.

    Olive-growing in Italy represents a particularly qualified and appreciated field in food-processing productions. The relevant interrelations with the history, landscape, environment and culture of our country make olive-growing particularly important not only for the economy of rural areas but also for the positive effects on landscape and surrounding environment. In fact olive-growing is defining itself more and more as a multifunctional enterprise. The presence of olive growers is also emph...

  15. Intestinal toxemia botulism in Italy, 1984-2005.

    Science.gov (United States)

    2007-06-01

    Botulism in humans is caused by botulinum neurotoxins, produced in most cases by Clostridium botulinum, although other Clostridia species are implicated as well. Of the five forms of botulism in humans, three are referred to as "infective": wound botulism, infant botulism, and adult intestinal botulism; the latter two forms are also referred to as "intestinal toxemia botulism" because the organism colonizes the lumen of the intestinal tract and produces botulinum neurotoxin in vivo. Twenty-three cases of infant botulism and three cases of adult intestinal botulism occurred in Italy between 1984 and 2005. Microbiological analyses of clinical, environmental, and food samples and analysis of clinical and epidemiological data revealed two main characteristics of intestinal toxemia botulism in Italy that are not common in cases in other countries: the isolation of a strain of C. butyricum that produced botulinum neurotoxin type E in 6 of 26 cases, including two cases of adult intestinal toxemia botulism, and the onset of botulism in these cases with concomitant severe gastrointestinal symptomatology. This report summarizes the microbiological, clinical, and epidemiological data of all cases of intestinal toxemia botulism that have occurred in Italy in the period 1984-2005.

  16. 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.

    In the last decade an increase of the number of red foxes in anthropized habitats across European countries, including Italy, has been observed. This pones implications in terms of disease transmission between wildlife and domestic animals; in fact, there are evidences of the role of foxes as reservoirs and amplifiers of a broad spectrum of parasites infecting pets. The present study evaluated the prevalence of Eucoleus boehmi, an emerging extra-intestinal nematodes of the Capillariinae subfamily, in red foxes. The nasal passages and sinuses of 179 red foxes culled from several areas of northern and central Italy were inspected and the mucosal surfaces were scrapped and examined for adult nematodes and eggs, microscopically and genetically identified. Overall 55 foxes (30.7%) were found to be infected with E. boehmi, i.e. 27 on inspection of the nasal passages and sinuses and 28 on mucosal flush and scraping. The occurrence of E. boehmi was significantly (p fox body condition (mean: 7.8 specimens). These results show that E. boehmi is highly prevalent in the red fox populations of certain areas of Italy. Epidemiological implications are discussed, with a special focus on the role that this wild canid may have in the increasing transmission of nasal eucoleosis to domestic dogs.

    Full Text Available The Dublin-born musician, Michael W. Balfe, was a singer, composerand conductor whose brilliant musical career was heavily influenced byformative experiences in Italy. In 1825, Balfe, interested in broadeninghis musical studies first went to Paris where he was introduced to thegreat composers, Luigi Cherubini and Gioachino Rossini, who took apersonal interest in him and his musical talents. On the advice of Rossinihe spent the next few years in Italy studying singing with the famousRossini singer, Filippo Galli, and taking music composition lessonsfrom Ferdinando Paer, in Rome. Later in Milan he studied harmonyand counterpoint with Vincenzo Federici. By 1831, when he was only23 years old, his first three operas had been produced in Palermo, Pavia,and Milan. He returned to London in August 1835, participatingwith the great Lablache, Tamburini, Rubini and Grisi in a concert inVauxhall Gardens. In 1834 he made his debut at La Scala, Milan, singingopposite the renowned mezzo-soprano, Maria Malibran in Rossini’sOtello. He appeared again with Malibran in Venice early in 1835,singing once more in Rossini and Bellini operas. Balfe worked as a singerand composer throughout the Italian peninsula/states during the years,1825-1835 and this article will chart these experiences and demonstratehow the time he spent in Italy and the people he met, influenced hislife and later career as an important and popular European composer.

    2013-12-01

    Full Text Available Bed 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.

  20. Migration, violence, and the role of psychiatry in Italy.

    Immigration to Italy has been increasing exponentially in the last decades due to the international political changes and conflicts in the Middle East. The relationship between immigration and crimes is a debated issue, and violent radicalization of second or third generations of migrants is under increased scrutiny. Consequently, many politicians and political parties use nationalist and xenophobic language. Inevitably, this will have an impact on reactions of the larger population, as well as that of migrants. Psychiatry can have a major role in dealing with immigrants' health needs, and also assessing risk and preventing violent behaviours due to mental disorders. It is possible to prevent some radicalization by employing strategies of education, leading to better integration of immigrants in the community (based on education, housing, work, etc.). However, often specialist services for migrants are lacking, and mental healthcare professionals may remain poorly trained. Italy is one of the major countries in Southern Europe with a large number of illegal and legal migrants; thereby, creating a major pressure on the resources. It is important to understand the links between globalization, migration, and violence in Italy, in order to prevent future radicalization. It is also useful for psychiatrists to act as advocates for migrants to help reduce xenophobia and discrimination supported by some national cultural and political movements. Ethno-psychiatric facilities should be promoted, as well as policies of support, integration, and prevention should be employed to promote legal migration through the European countries.

  1. 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.

    In the European scenario Municipal Waste Management (MWM) is very heterogeneous, and many countries did not achieve yet the decoupling between economic growth and MW production. The objectives of the study were to evaluate temporal trends of MWM and economic indicators to evidence differences between Germany and Italy, and to assess the relationship between economic indicators and MW production, to highlight whenever decoupling was achieved. Time series analyses (1995-2010) of data related to MWM and income/consumption indicators were performed, and simple regression analyses were run to evaluate the relationship between economic drivers and MW production. Income/consumption indicators show a constant increment in both countries, while different trends appear for MWM. German MW production was reduced, and, over the years, the main disposal method rose from landfill towards recycling. On the contrary, Italian MW production increased, and landfilling has been always the most common method for disposal waste. Besides, the percentage of MW collected separately and packaging recovered was higher in Germany than in Italy for all the investigated period. Moreover, Germany appears to have decoupled MW production from economic growth, while Italian MW production is significant positively associated to it. Germany emerges as a virtuous country, while Italy appears as the "example not to follow". Differences could be determined by the contribution of several factors, such as educational levels, urbanization, population characteristics, employment/unemployment rates, expenditure in research and health issues, that should be studied indeed.

    Full Text Available In Italy at the end of 19th Century, malaria cases amounted to 2 million with 15,000-20,000 deaths per year. Malignant tertian malaria was present in Central-Southern areas and in the islands. Early in the 20th Century, the most important act of the Italian Parliament was the approval of laws regulating the production and free distribution of quinine and the promotion of measures aiming at the reduction of the larval breeding places of Anopheline vectors. The contribution from the Italian School of Malariology (Camillo Golgi, Ettore Marchiafava, Angelo Celli, Giovanni Battista Grassi, Amico Bignami, Giuseppe Bastianelli to the discovery of the transmission’s mechanism of malaria was fundamental in fostering the initiatives of the Parliament of the Italian Kingdom. A program of cooperation for malaria control in Italy, supported by the Rockefeller Foundation started in 1924, with the establishment of the Experimental Station in Rome, transformed in 1934 into the National Institute of Public Health. Alberto Missiroli, Director of the Laboratory of Malariology, conducted laboratory and field research, that with the advent of DDT brought to Italy by the Allies at the end of the World War II, allowed him to plan a national campaign victorious against the secular scourge.

    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

    based on seismological and volcanological data, integrated with strain, geochemical, gravimetric and magnetic parameters. In the code, is necessary to fix an appropriate forecasting time window. On open-conduit volcanoes as Mt. Etna, a forecast time window of a month (as fixed in other applications worldwide) seems unduly long, because variations of the state of the volcano (significant variation of a specific monitoring parameter could occur in time scale shorter than the forecasting time window) are expected with shorter time scale (hour, day or week). This leads to set a week as forecasting time window, coherently with the number of weeks in which an unrest has been experienced. The short-term vent opening hazard assessment will be estimated during an unrest phase; the testing case (2001 July eruption) will include all the monitoring parameters collected at Mt. Etna during the six months preceding the eruption. The monitoring role has been assessed eliciting more than 50 parameters, including seismic activity, ground deformation, geochemistry, gravity, magnetism, and distributed inside the first three nodes of the procedure. Parameter values describe the Mt. Etna volcano activity, being more detailed through the code, particularly in time units. The methodology allows all assumptions and thresholds to be clearly identified and provides a rational means for their revision if new data or information are incoming.

    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

    The organization of a homogeneous medical emergency system was developed in Italy in 1999. Currently, 104 stations manage medical emergencies with ambulances and 47 helicopter-capable bases for more difficult missions. The current study describes the organization of the helicopter emergency system in Italy. Data were collected from questionnaires filled in by each base commander. Six hundred twenty-seven physicians are enrolled in helicopter-capable base emergency teams. Of those physicians, 89.5% are specialists in anesthesiology. Professional nurses are enrolled in 46 bases. Twenty-six bases specialize in search-and-rescue (SAR) missions (which take place in geographically unfriendly terrain), where a mountain rescue technician (CNSAS) is part of the team. Twenty-one bases are for missions in geographically friendly terrain (HEMS bases). Eight bases provide 24-hour service. Specialized training is given to physicians and nurses: it is considered of first level (high standard) in 21 bases, of second level (intermediary) in 17 bases, and of third level (low) in nine bases. In the mountain bases (Alps and Apennines), the more widely used helicopters are the AB412 and the BK117C1. During 2004, there were 20,660 primary interventions and 7,790 secondary interventions. From 1999 to 2004 there was a 33% increase of activity for primary and 35% for secondary interventions. The data show the activity of the helicopter-ambulance service, the role of anesthetists within the helicopter-based Advanced Cardiac Life Support (ACLS) team, and the diverse organization of training for medical staff in different regions of Italy.

    The complexity of end-of-life care, represented by a large number of units caring for dying patients, of different types of organizations motivates the importance of measure the quality of provided care. Despite the law 38/2010 promulgated to remove the barriers and provide affordable access to palliative care, measurement, and monitoring of processes of home care providers in Italy has not been attempted. Using data drawn by an institutional voluntary observatory established in Italy in 2013, collecting home palliative care units caring for people between January and December 2013, we assess the degree to which Italian home palliative care teams endorse a set of standards required by the 38/2010 law and best practices as emerged from the literature. The evaluation strategy is based on Rasch analysis, allowing to objectively measuring both performances of facilities and quality indicators' difficulty on the same metric, using 14 quality indicators identified by the observatory's steering committee. Globally, 195 home care teams were registered in the observatory reporting globally 40 955 cured patients in 2013 representing 66% of the population of home palliative care units active in Italy in 2013. Rasch analysis identifies 5 indicators ("interview" with caregivers, continuous training provided to medical and nursing staff, provision of specialized multidisciplinary interventions, psychological support to the patient and family, and drug supply at home) easy to endorse by health care providers and 3 problematic indicators (presence of a formally established Local Network of Palliative care in the area of reference, provision of the care for most problematic patient requiring high intensity of the care, and the percentage of cancer patient dying at Home). The lack of Local Network of Palliative care, required by law 38/2010, is, at the present, the main barrier to its application. However, the adopted methodology suggests that a clear roadmap for health facilities

    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

    Diabetes mellitus is an increasingly common chronic disease that has a great impact not only in terms of clinical effects, but also in terms of economic burden worldwide. Expenditures due to diabetes derive essentially from direct and indirect costs. Current estimates of global healthcare expenditures due to diabetes are US$376 billion and are expected to increase to US$490 billion by 2030. In particular, costs associated with diabetes-related complications represent the most relevant part of the national healthcare expenditure for diabetes and are higher than the costs of managing diabetes itself. The major expenditure depends on the type and the number of complications: cardiovascular complications increase direct costs, especially for hospitalization. Moreover, diabetic comorbidity has a greater economic impact on the health expenditure in comparison with those patients without diabetes. In Europe, the CODE-2 study was the first attempt to evaluate the costs of diabetes: the annual costs per patient were estimated at €2384 and the highest value, €2991, was registered in Italy. This indicates an overall annual cost of €5170 million for the whole Italian population with diabetes. Current estimates for 2010 healthcare expenditure for diabetes are US$105 billion (10% of total healthcare expenditure, US$2046 per person) for the whole European region, and US$11 billion (9% of total healthcare expenditure, US$2087 per person) for Italy. More studies are needed in order to better define the real significance of the healthcare costs of diabetes in Italy. An effective therapy with a good metabolic control can reduce the risk of complications and represents a valid strategy from an economic point of view.

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

    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.

    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.

    Characterization of risks to human health is determinant for risk management and population surveillance. This study represent the first work at national scale for Italy about arsenic occurrence, distribution and health impact. We analyzed the As geochemical distribution in different environmental matrices on the whole Italian territory, and assessed both carcinogenic and non-carcinogenic risks for different exposure routes and age groups. The results demonstrate that, in Italy, arsenic is present in significant concentrations both in water (up to 27.2 µg/L) and soils (up to 70 mg/kg). Its presence is mainly controlled by geological processes and locally reflects the industrial history of the Country. The population of the Central Italy, where high content of arsenic in the analyzed samples is due to the presence of alkaline volcanics, are the most exposed to the health risk. Based on the results of our work, it is clear that the consumption of tap water for potable use is the most impactful route for As daily exposure and play an important role in governing potential cancer and non-cancer risks for the considered population. It is interesting to observe that the Incremental Life Cancer Risk through water ingestion show that almost 80% of data falls above the internationally accepted benchmark value of 1 x 10-5. Moreover it was demonstrated that childhood is the most susceptible age stage to As exposure. Geochemical mapping provided a useful tool to spatially analyze and represent data and to highlight the most critic areas and the most exposed population to arsenic at national scale. In conclusion, this study improve knowledge about As occurrence for an entire Country, recognizing an health emerging problem. It might be a good starting point to support the urgently needed policy actions, in order to prevent and reduce the health risk. Moreover, the performed method in this case study research is potentially generalizable and applicable in other countries.

    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.

    Canine parvovirus type 2 (CPV-2) is responsible of acute hemorrhagic gastroenteritis in young dogs. CPV-2 emerged in 1978 in the USA, but new antigenic types, CPV-2a, 2b and 2c, have completely replaced the original type. In this study, we analyzed 81 animals collected in Sardinia, Italy. The VP2 sequence analysis of 27 positive samples showed that all antigenic CPV-2 types are circulating. CPV-2b seems to be the most widespread variant, followed by CPV-2a. Furthermore, 12 CPV-2b strains displayed further amino acid substitutions and formed a separate cluster in a phylogenetic tree, indicating regional genetic variation.

    2017-04-01

    Despite its generally mild climate, Italy, as most of the Mediterranean region, is prone to the development of "super-extreme" events with extraordinary rainfall intensities. The main triggering mechanisms of these events is nowadays quite well known, but more research is needed to transform this knowledge in directions to build updated rainstorm hazard maps at the national scale. Moreover, a precise definition of "super-extremes" is still lacking, since the original suggestion of a second specific EV1 component made with the TCEV distribution. The above considerations led us to consider Italy a peculiar and challenging case study, where the geographic and orographic settings, associated with recurring storm-induced disasters, require an updated assessment of the "super-extreme" rainfall hazard at the country scale. Until now, the lack of a unique dataset of rainfall extremes has made the above task difficult to reach. In this work we report the results of the analysis made on a comprehensive and uniform set of rainfall annual maxima, collected from the different authorities in charge, representing the reference dataset of extremes from 1 to 24 hours duration. The database includes more than 6000 measuring points nationwide, spanning the period 1916 - 2014. Our analysis aims at identifying a meaningful population of records deviating from an "ordinary" definition of extreme value distribution, and assessing the stationarity in the timing of these events at the national scale. The first problems that need to be overcome are related to the not uniform distribution of data in time and space. Then the evaluation of meaningful relative thresholds aimed at selecting significant samples for the trend assessment has to be addressed. A first investigation attempt refers to the events exceeding a threshold that identify an average of one occurrence per year all over Italy, i.e. with a 1/1000 overall probability of exceedance.

    Many individuals around the world follow vegetarian diet. The aim of this study was to examine the variables associated to a vegetarian diet. Data were drawn from the national cross-sectional survey "Health and use of health care in Italy". Vegetarian habit was prevalent in 0.79% of sample, mainly females. Multivariate model has confirmed the association between vegetarianism and females, age, level of education, marital status separated/divorced/single, diabetes, bad state of perceived health. Little to no research has been conducted in this area until now. As for all types of diet, the vegetarian one should be controlled.

    Full Text Available A small pachypleurosaurid collected in the Besano area of Italy, is described. A comparative analysis of size and proportions with other pachipleurosaurids suggest it represents a juvenile specimen of Neusticosaurus pusillus. The specimen represents a peculiar taphonomic case: the centra of the dorsal vertebrae are clustered together in the pectoral area while the rest of the trunk is virtually undisturbed, suggesting that disarticulation of dorsal vertebral elements may have occurred before decay of integumental soft parts, possibly before the carcass reached the bottom of the basin.

    Aichi virus (AiV) is suspected to play a role in viral gastroenteritis in humans. In this study, we assessed the presence of AiV in untreated influent sewage samples collected at four wastewater treatment plants in central Italy. AiV was detected in 6 (12.5 %) of the 48 specimens and in all plants. All of the Italian strains showed the highest nucleotide and amino acid sequence identity to genotype B AiV detected recently in Asia, especially in China.

    Italy is the real Cinderella among coal users for electricity generation, gaining first prize on the international stage for squandering L1000 bn of energy annually, using gas instead of coal. Much of the reason for this is environmentalist objections to coal-fired plant. Coal is bought by ENEL on small long-term contracts - ensuring a diversity of supply. This could change, if and when the privatisation of ENEL finally takes place. Other consumers of imported coal include the cement industry, the steel industry and possibly independent power producers. 2 figs.

  3. 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

    We report on geoelectric measurements taken at 70 and 120 km from the epicenter of the M6.2 Amatrice Central Italy Earthquake Aug. 24, 2016. Two stations, each consisting of 12 buried electrodes at depths of 1 to 3 meters, recorded ground EMF values once per second for approximately one year prior to the earthquake. Several geoelectric anomalies suggest the incidence of seismic electric signals in the weeks leading up to the earthquake. Notably, EMF values in the DC regime deviated progressively farther from baseline levels and AC components exhibited episodes of significant nonstationarity in their frequency spectra as the earthquake approached.

    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.

    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.

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

    La Vigna, F.; Teoli, P.; Mazza, R.; Leoni, G.; Capelli, G.

    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.

    2010-03-01

    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.

    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.

    Forestieri, Angelo; Blenkinsop, Stephen; Fowler, Hayley; Lo Conti, Francesco; Noto, Leonardo

    2016-04-01

    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.

  1. Karst subsidence in South-Central Apulia, Southern Italy.

    Directory of Open Access Journals (Sweden)

    Delle Rose Marco

    2002-01-01

    Full Text Available Subsidence in the karst of Apulia (Southern Italy, one of the classical karst areas of Italy, is described in this paper. The carbonate rocks that make up the geological structure of the Apulia region are affected by subsidence, which is of different type and intensity depending upon geological, topographical, and hydrogeological conditions. In particular, we discriminate between inland subsidence and coastal subsidence. Inland subsidence is generally restricted to the presence of individual cavities, either empty or partly or totally filled with deposits produced by dissolution of soluble rocks underground. Locally, such subsidence can cause severe effects on anthropogenic structures above. The coastal plains of Apulia, particularly the southernmost part (Salento Peninsula, show interesting karst subsidence. Here the main feature is the development of compound sinks extending for several thousands of square metres, or the formation of individual, mostly circular, dolines along the coastline. Occurrence of one or the other of the above features seems to depend upon topographical conditions, and also upon their relationship with sea level oscillations.

  2. Obtaining Reimbursement in France and Italy for New Diabetes Products

    2015-01-01

    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.

    Treatment choice for chronic HBV infection is a continuously evolving issue, with a wide range of options. We aimed to evaluate the current practice of HBV therapies in the real world in Southern Italy. A prospective study enrolling over a six month period (February-July 2010) all consecutive HBsAg positive subjects, never previously treated, referred to 16 liver units in two Southern Italy regions (Calabria and Sicily). Out of 247 subjects evaluated, 116 (46.9%) had HBV-DNA undetectable or lower than 2000 UI/ml. There were 108 (43.7%) inactive carriers, 103 (41.7%) chronic hepatitis, and 36 (14.6%) liver cirrhosis. Antiviral treatment was planned in 94 (38.0%) patients (26 cases with Interferon or Pegylated Interferon and 68 with nucleos(t)ides analogues). As many as 49.5% of subjects with chronic hepatitis did not receive antiviral treatment. The majority of chronic HBsAg carrier referring centres for evaluation were not considered suitable for antiviral treatment. Nucleos(t)ides analogues are the preferred first choice for therapy. A long-lasting period of observation may be needed to make appropriate therapeutic decisions in several cases. Copyright © 2012 European Federation of Internal Medicine. Published by Elsevier B.V.

    Full Text Available As the title suggests, this work is aimed at analyzing food-related neophobia in terms of migration. We will try to explain if cultural differences of migration groups have an impact even in food choices; if, by living in a foreign country, amid other culinary attitudes, people become more open to the new recipes (less neophobic of the hosting culture, or remain a$ ached to the culinary attitudes of their original country (more neophobic. Current research studies to scientific literature have never considered food neophobia in terms of migration experience. That is why we were induced to carry out this research. The research was conducted on a non-representative sample of 200 individuals, 100 Albanians residing in Italy and 100 Albanians residing in Albania (answering rate 100%. The first goal is to find out if there is a relation between food neophobia and general neophobia (fear from unknown people and places. So, to high levels of general neophobia (fear from new situations and unknown people of participants even high levels of food neophobia (fear to try new recipes should correspond, and vice versa. The second goal is to measure food neophobia differences between Albanians with migration experience (currently residing in Italy and Albanians with no migration experience (currently residing in Albania.

    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.

  6. The Establishment of an Operational Earthquake Forecasting System 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.

    The considerable increase of non-standard labor contracts, unemployment and inactivity rates raises the question of whether job insecurity and the lack of job opportunities affect physical and mental well-being differently from being employed with an open-ended contract. In this paper we offer evidence on the relationship between self-reported health and the employment status in Italy using the Survey on Household Income and Wealth (SHIW); another aim is to investigate whether these potential inequalities have changed with the recent economic downturn (time period 2006-2010). We estimate an ordered logit model with self-reported health status (SRHS) as response variable based on a fixed-effects approach which has certain advantages with respect to the random-effects formulation: the fixed-effects nature of the model also allows us to solve the problems of incidental parameters and non-random selection of individuals into different labor market categories. We find that temporary workers, first-job seekers and unemployed individuals are worse off than permanent employees, especially males, young workers, and those living in the center and south of Italy. Health inequalities between permanent workers and job seekers widen over time for male and young workers, and arise in the north of the country as well.

    Variegate Porphyria (VP) is an autosomal dominant disorder found worldwide but is rare in Italy. In this study we provide an overview of clinical, biochemical and genetic background of 33 Italian VP patients diagnosed in the last fifteen years. About 70% of patients had experienced clinical symptoms: 43.4% had photosensivity, 8.7% acute attacks and 47.8% both. Among the 33 patients, 14 different mutations were identified. Of these only 6 defects have been previously described in other countries and 8 are unique having been identified for the first time in Italy. Two of these, the c.851G>T and the c.1013C>G, were found in two and four unrelated families respectively. No mutation has been found in homozygosis and no significant correlation has been observed between specific clinical and biochemical manifestations and the type of mutation. In contrast, normal faecal protoporphyrin excretion was high predictive of silent phenotype. Normal urinary excretion of PBG and ALA, predicted absence of neurovisceral symptoms. This paper represents the first compilation of data on genotype-phenotype relation in Italian patients with VP.

  9. 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.

    2016-01-01

    The Italian Society for Pediatric Infectious Diseases created a registry on children with infective endocarditis (IE) hospitalized in Italy. A cross-sectional survey was conducted on patients hospitalized due to IE in Italian paediatric wards between January 1, 2000, and June 30, 2015. Over the 15-year study period, 47 IE episodes were observed (19 males; age range, 2-17 years). Viridans Streptococci were the most common pathogens among patients with predisposing cardiac conditions and Staphylococcus aureus among those without (37.9% vs. 5.5%, p = 0.018, and 6.9% vs. 27.8%, p = 0.089, respectively). Six of the 7 (85.7%) S. aureus strains were methicillin-resistant. The majority of patients with and without predisposing cardiac conditions recovered without any complications. In Italy, paediatric IE develops without any previous predisposing factors in a number of children, methicillin-resistant S. aureus has emerged as a common causative agent and the therapeutic approach is extremely variable.

    Scientific literature suggests that in developed countries food is predominantly wasted at the consumption stage of the food supply chain. This study aims to profile consumers' attitude to waste food in Italy investigating households' behaviours leading to food waste generation by addressing what is being wasted and why it is wasted. The work is based on a survey performed in Italy on a heterogeneous sample of 3,087 respondents. A cluster analysis was performed to detect consumers' profiles. Results, based on self-reporting, allow to sketch different 'waster' types, providing a picture of food waste related to eating, shopping, and storage behaviours and suggesting a number of differences existing in terms of perceived quantities and causes of generated food waste. Out of seven profiles identified, four are the most representative ones in terms of size: the conscious-fussy type, who wastes because food doesn't smell or look good; the conscious-forgetful type, who forgets what is in the fridge or on the shelves; the frugal consumer who tends not to consume fruits and vegetables and declares to waste nothing (or almost nothing); and the exaggerated cook, who overbuys and overcooks. Profiling specific waste types can help to better understand if groups with common characteristics exist, what their specific features are and what levers can be employed to stimulate a change in their behaviour.

    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.

    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. © 2014 Family Process Institute.

  14. Language and Identities: The Exceptional Normality of Italy

    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.

  15. Gender equity and fertility intentions in Italy and the Netherlands

    2008-02-01

    Full Text Available Fertility levels have fallen drastically in most industrialized countries. Diverse theoretical and empirical frameworks have had difficulty in explaining these unprecedented low levels of fertility. More recently, however, attention has turned from classic explanations, such as women's increased labour market participation, to gender equity as the essential link to understand this phenomenon. The increase in women's labour market participation did not prompt an increase in men's domestic duties, which is often referred to women's 'dual burden' or 'second shift'. Institutions and policies within countries also facilitate or constrain the combination of women's employment with fertility. This paper provides an empirical test of gender equity theory by examining whether the unequal division of household labour leads to lower fertility intentions of women in different institutional contexts. Italy constitutes a case of high gender inequity, low female labour market participation and the lowest-low fertility. The Netherlands has moderate to low gender inequity, high part-time female labour market participation and comparatively higher fertility. Using data from the 2003 Italian Multipurpose Survey - Family and Social Actors and the 2004/5 Dutch sample from the European Social Survey, a series of logistic regression models test this theory. A central finding is that the unequal division of household labour only has a significant impact on women's fertility intentions when they already carry the load of high paid work hours or children, a finding that is particularly significant for working women in Italy.

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

    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.

  17. Slow earthquakes and low frequency tremor along the Apennines, Italy

    2008-06-01

    Full Text Available This paper reviews the main observations on slow earthquakes and low frequency tremor made along the Apennines, the main seismic active zone of Italy. These observations have been made using a geodetic interferometer system operating since 1994 in the underground tunnel of Gran Sasso, central Italy, and an underground seismic array (UNDERSEIS operating since 2002 in the same environment. The observations made in recent years indicate that both phenomena are quite rare and apparently uncorrelated. Slow earthquakes, mainly recorded in 1997 and occasionally later, have probably been caused by the activity of a shallow fault system located near the interferometers. Until now only one tremor episode characterized by low frequency content and duration of several hours has been detected in January 2004, without any correlations with the occurrence of slow or regular earthquakes. The signal to noise ratio of this event is very low, but the results of our detailed analysis show that its frequency contents and wave field characteristics are compatible with a low frequency non volcanic tremor.

    Full Text Available In the last ten years, the question about the possibility of entering the psychological scientific in-formation has come to the fore. 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.

    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.

    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.

    Full Text Available Esca is a grapevine disease occurring in all vine-growing areas, including Italy. Multiple fungi that have been associated with esca spread by releasing aerial spores that infect pruning cuts and wounds. The aim of the study was to determine the occurrence of the most common fungi associated with esca in Umbria (central Italy and to fi nd under what weather conditions they release their spores. Disease incidence was also determined in the summers of 2006 and 2007 on ten grapevine cultivars (Cabernet Sauvignon, Grechetto, Sangiovese, Trebbiano toscano, Pinot bianco, Trebbiano spoletino, Ciliegiolo, Montepulciano, Chardonnay and Merlot growing together in the same vineyard. Visual inspection of the vines showed that all cultivars were susceptible to esca, but that esca incidence differed in intensity between cultivars. In both years, esca incidence was higher with Cabernet Sauvignon, Sangiovese and Trebbiano toscano, and lower with Montepulciano and Merlot. Disease incidence went up in summer. Phaeomoniella chlamydospora was isolated from vine samples showing dark wood streaking, and Fomitiporia mediterranea from samples with white rot, confi rming that these fungi are involved in esca. Spores of P. chlamydospora were trapped from March to December 2007. Spore release was affected by weather parameters (rain and temperature.

    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.

  3. 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 aim of this study was to estimate the cost of "brain" disorders in Italy. Country-specific prevalence and health-economic data on addiction, affective, anxiety and psychotic disorders, tumours, dementia, epilepsy, migraine/other headaches, multiple sclerosis, Parkinson's disease, stroke and head trauma were reviewed. Direct medical/non-medical and indirect costs were computed. Population-based samples and national or regional registries were used. The Italian population expected with a brain disorder was 12.4 million in 2004. The highest cost per case was for tumours and multiple sclerosis; the lowest was for anxiety disorders and migraine. Dementia (8.6 billion euros), psychotic and affective disorders (18.7 billion euros), migraine (3.5 billion euros) and stroke (3.4 billion euros) represented the highest total costs. Direct medical costs were predominant for psychiatric and neurosurgical disorders, direct non-medical costs for dementia, and indirect costs for neurological disorders. The total cost of brain disorders in Italy was 40.8 billion euros, 3% of the gross national product, and 706 euros per Italian citizen/year. This figure is however likely to be underestimated as it is based on retrospective methodology and samples of brain disorders, and does not include intangible costs.

    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. © 2015 Diabetes Technology Society.

    The occurrence of Mycobacterium spp. in freshwater and marine ornamental fish was studied in Italy from June 2002 to May 2005. Two surveys were carried out, one of aquarium fish sent to the Laboratory for diagnosis, and the other of prevalence of infection by mycobacteria in ornamental fish imported into Italy. Bacterial isolation was carried out from the spleen, kidney and liver, and the isolates were subsequently identified by biochemical tests. In the first survey, 387 fish were examined and Mycobacterium spp. were isolated from 181 (46.8%) fish. In the second survey 127 batches of ornamental fish from different countries were examined. Mycobacterium spp. were isolated from 38 (29.9%) batches. The following species were found: M. fortuitum, M. peregrinum, M. chelonae, M. abscessus, M. marinum, M. gordonae, M. nonchromogenicum and M. interjectum. There was a high prevalence of infection independent of the presence of macroscopic lesions. Mycobacterium fortuitum and M. chelonae were more prevalent than M. marinum in the samples examined.

    2011-12-01

    We present the latest updating and the complete collection of data on the contemporary stress orientations in Italy. Data are relative to different stress indicators: borehole breakouts from deep drillings, crustal earthquake focal mechanisms and fault data. With respect to the previous compilation, performed in 2004, 206 new entries complete the definition of the horizontal stress orientation and tectonic regime in the most part of the territory, and bring new information mainly in Sicily and along the Apenninic belt. With an increase of 37% with respect to the previous compilation, now the global Italian dataset consists of 499 records with a reliable quality for stress maps. The total dataset includes the following active stress indicators: 56% borehole breakouts, 39% single earthquake focal mechanisms, and 5% represented by formal inversions of focal mechanisms, faults and overcoring data. A quality ranking between A and E is assigned to each stress data, with A being the highest quality and E the lowest. Only A-, B- and C-quality stress indicators are considered consistent for analyzing stress patterns. Depth interval of the entire dataset is between 0 to 40 km. The results in map are reported in terms of minimum horizontal stress (Shmin) because most of earthquakes present an extensional regime. Concerning breakouts, their orientations correspond to Shmin; since all the considered faults are normal faults, we assume the Shmin direction as perpendicular to the fault strike when no information on slip direction is available. The achieved results can be summarized in 3 main points: i) in some areas of Italy (Sicily, Friuli and Po Plain in the northern Italy), the alignment of horizontal stresses closely matches the ~N-S direction of ongoing crustal motions with respect to stable European plate. This result can be associated to the first-order stress field that drives the plate movement; ii) along the entire Apenninic belt - from north to south- a diffuse

    This report is an update of similar previous papers that have been published by the ONS (Osservatorio nazionale screening, National Centre for Screening Monitoring) since 2002. Data for the survey come from several different programmes that may have changed over time, and may have different settings of organisation and management. During 2010, the first slight decrease in theoretical extension was recorded. Currently, all Italian regions have implemented screening programmes. In 2010, almost 2,496,000 women aged 50-69 years were invited to have a screening mammogram, and more than 1,382,000 were screened. Theoretical extension was 91.7%, while actual extension was 69.1%. An imbalance in extension is still present when comparing northern and central Italy to southern Italy, which only has a 75% coverage by organised screening. The Italian mean value (69%) of two-year extension (period 2009-2010) suggests that, at full capacity, Italian programmes are able to invite only three quarters of the target population. The percentage of women screened during 2010 was 36.7% of the national target population. During the last few years, participation rates were substantially stable, around 55-57% for crude rate, and 59-61% for adjusted rate, respectively. A decreasing trend towards the South of Italy is evident for this parameter, too. Many programmes work with low volumes of activity (below 10,000 or even 5,000 examinations per year), and only one region surpassed the desirable level of at least 20,000 examinations for each programme. Referral rates of 8.8% at first screening and 4.6% at repeat screening were recorded. Direct standardised detection rate was 6.2x1,000 at first screening and 4.3x1,000 at repeat screening, while benign to malignant ratio for first and repeat screening was 0.26 and 0.12, respectively. Detection rate of invasive cancers ≤10 mm was 1.36x1,000 at first screening and 1.49x1,000 at repeat screening; the proportion of in situ carcinomas was 13.9% and

    to evaluate self-perceived health status of immigrants in Italy. cross-sectional study based on the representative national samples of the multipurpose surveys "Health conditions and use of health services" conducted in 2005 and 2013 by the Italian National Institute of Statistics (Istat). the study was conducted on the age group of 18-64: No. 80,661 in 2005, among which 3.2% were immigrants, and No. 72,476 in 2013, among which 7.1% were immigrants. prevalence rate ratios (PRR) calculated through log-binomial regression models, stratified by survey edition and gender, by evaluating the association between the Physical Component Score (PCS), the Mental Component Score (MCS), and the overall health index and citizenship. Adjustment for the following confounding factors was performed: age, educational level, working condition, perceived economic resources, body mass index (BMI). in 2005, immigrants had a lower probability of poor-perceived physical health, both among men (PRR: 0.79; 95%CI 0.70-0.89) and women (PRR: 0.89; 95%CI 0.82- 0.97), compared to Italians. In 2013, the perceived health advantage of immigrants was reduced for both genders (PRR males: 0.87; 95%CI 0.80-0.95; PRR females: 0.94; 95%CI 0.88-0.99). In the considered period, the prevalence of people with worse mental health conditions increases, with lower PRR among immigrants, compared to Italians. Higher probability of «NOT good» overall perceived health was also observed among immigrants residing in Italy for at least 10 years (PRR men: 1.24; PRR women: 1.15) and among immigrants men from America (PRR: 1.35). from 2005 to 2013, immigrants seemed to maintain a better perception of health status than Italians. Nevertheless, study results show a decrease in self-perceived health, particularly mental health, in the considered period - apart from demographic, socioeconomic, and lifestyle factors - as well as a worse overall self-perceived health status among immigrants who stayed in Italy longer.

    Emilia Romagna, a northern Italian region, has a population of 4.27 million, of which 9.7% are immigrants. The objective of this study was to investigate the epidemiology of tuberculosis (TB) during the period 1996-2006 in not Italy-born compared to Italy-born cases. Data was obtained from the Regional TB surveillance system, from where personal data, clinical features and risk factors of all notified TB cases were extracted. 5377 TB cases were reported. The proportion of immigrants with TB, over the total number of TB cases had progressively increased over the years, from 19.1% to 53.3%. In the not Italy-born population, TB incidence was higher than in Italians (in 2006: 100.7 cases per 100,000 registered not Italy-born subjects and 83.9/100,000 adding 20% of estimated irregular presences to the denominators. TB incidence among Italians was 6.5/100,000 Italians). A progressive rise in the not Italy-born incident cases was observed but associated with a decline in TB incidence. Not Italy-born cases were younger compared to the Italy-born cases, and more frequently classified as "new cases" (OR 2.0 95%CI 1.61-2.49 for age group 20-39); 60.7% had pulmonary TB, 31.6% extra pulmonary and 7.6% disseminated TB. Risk factors for TB in this population group were connected to lower income status (homeless: OR 149.9 95%CI 20.7-1083.3 for age group 40-59). In low-incidence regions, prevention and control of TB among sub-groups at risk such as the foreign-born population is a matter of public health concern. In addition, increasing immigration rates may affect TB epidemiology. TB among immigrants is characterized by particular clinical features and risk factors, which should be analyzed in order to plan effective action.

    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.

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.

    The success of emergency intervention to control contagious animal diseases is dependent on the preparedness of veterinary services. In the framework of avian influenza preparedness, the Italian Ministry of Health, in cooperation with the National Reference Centers for Epidemiology and Avian Influenza, implemented an electronic learning course using new web-based information and communication technologies. The course was designed to train veterinary officers involved in disease outbreak management, laboratory diagnosis, and policy making. The "blended learning model" was applied, involving participants in tutor-supported self-learning, collaborative learning activities, and virtual classes. The course duration was 16 hr spread over a 4-wk period. Six editions were implemented for 705 participants. All participants completed the evaluation assignments, and the drop out rate was very low (only 4%). This project increased the number of professionals receiving high-quality training on AI in Italy, while reducing expenditure and maximizing return on effort.

  19. Continuous SO2 flux measurements for Vulcano Island, Italy

    2012-06-01

    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.

    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.

    Femicide is defined as the killing of a woman by a man because she is a woman. The incidence of femicide has increased over the past few years and accounted for 30.9% of all homicides in 2011 in Italy. Certain features are usually present including asphyxiation as the mechanism of death, an intimate partner as murderer, and a history of sentimental relationship between the victim and the offender. In this paper, we analyse the Italian experience of femicide comparing it with the international scenario. We present four cases of femicide showing peculiar mechanisms of death resulting from various methods of asphyxiation. In all the cases, there had been a relationship between the victim and the offender. We discuss the mechanism of asphyxiation used to kill the women, emphasizing the necessity of a careful evaluation of all data available to reach the correct conclusion in atypical cases of femicide.

    The aim of the study was to determine the burden of Toxoplasma gondii-infections in sheep in Sicily, southern Italy and the risk factors for infection. Sera from 1961 sheep were collected just before slaughtering from 62 farms located in 8 out of 9 Sicilian administrative districts. The sera were...... analysed for Toxoplasma-specific IgG antibodies using commercially available enzyme-linked immunosorbent assay. Sheep less than 4 weeks old were further analysed by ELISA for Toxoplasma-specific IgM-antibodies. Data on farm size and location were obtained from slaughterhouse sanitary reports and through...... structured telephone interviews of the veterinary officers from public health districts. The overall seroprevalence of Toxoplasma-specific IgG-antibodies were 49.9% (937/1876) by ELISA. Eighty-seven (54/62) percent of the farms had at least one Toxoplasma-positive animal. All the farms fed the animals...

    Full Text Available Little attention has been paid to the herpetological fauna of the Simbruini Mountains Regional Park, Latium (Central Italy. In this study, we surveyed 50 sites in the course of about ten years of field research, especially during the period 2005-2008. Nine amphibian species, four Caudata and five Anura, 60.0% out of the 15 amphibian species so far observed in Latium, were discovered in the protected area: Salamandra salamandra, Salamandrina perspicillata, Lissotriton vulgaris, Triturus carnifex, Bombina pachypus, Bufo balearicus, Bufo bufo, Rana dalmatina, Rana italica. Physiography of sites has been detailed together with potential threatening patterns. For each species the following topics have been discussed; ecology of sites, altitudinal distribution, phenology, sintopy. Salamandra salamandra and Bombina pachypus are at higher risk. The importance of the maintenance of artificial/natural water bodies for the conservation management of amphibian population of this territory is discussed.

  4. Genetic analysis of congenital hemimelia in buffaloes from Southern Italy

    Directory of Open Access Journals (Sweden)

    Simona Tafuri

    2013-04-01

    Full Text Available Hemimelia is a common congenital limb abnormality found in water buffaloes from Southern Italy. In humans, such defect has been associated with mutations in WNT7A and ESCO2 genes. These two candidate genes were analyzed by polymerase chain reaction in the genomic DNA extracted from the blood of buffaloes, and cows for control. No differences in WNT7A and ESCO2 sequences between affected and healthy buffaloes were identified. However, comparing sequences of control cows and buffaloes, WNT7A showed simple species polymorphisms, and ESCO2 showed seven base-pair substitutions. These results demonstrate that limb malformations in buffaloes are not related to congenital defects in WNT7A gene. Interestingly, our findings highlight for the first time differences in the sequences of WNT7A and ESCO2 genes between buffaloes and cows.

    This publication provides a detailed look at the specific systems in Italy for responding to an oil supply crisis. In 2007, the IEA published ''Oil Supply Security: Emergency Response of IEA Countries''. Rather than waiting for the completion of the current review cycle to renew this full publication, the IEA will provide updates to the country chapters as these become available following the specific country's review. The aim of series of publications is to provide an overview of the IEA oil emergency response system and a detailed look at the specific systems in each IEA country for responding to an oil supply crisis. The 2007 publication represented the findings of a five year review cycle of the emergency response mechanisms in IEA member countries. Since the 2007 publication, the IEA has started a new cycle of reviews which now includes reviewing gas emergency policies.

    ATLS Courses were introduced in the USA in 1980 and have been taught in Italy since 1994. Through theoretical lessons and practical sessions, their scope is to provide proper training for doctors with every kind of speciality who work in Emergency Departments, in order to prepare them to rapidly and effectively intervene on a patient who has suffered a serious trauma. Universities, in fact, do not prepare doctors adequately on this topic, while the application of the ATLS method in the first hours after trauma can effectively improve the prognosis of the patient. This study collects the data of the Italian experience in ATLS training, which has been carried out under the aegis of the Italian Chapter of the American College of Surgeons. The ATLS Courses have become widespread throughout our Country, which today is the fourth in the world for number of courses held every year.

    2013-12-01

    Full Text Available Following the study of epiphytic lichens in 30 apple orchards from Poland, Slovakia and Italy the list of 74 taxa was prepared. The most common are the meso- to xerophytic and heliophilous species. The highest number of taxa was observed in Slovak orchards. Moreover, lichens shared with at least one other country were also noted mainly in Slovakia. Bark of apple trees seems to create favourable habitats for Bacidia rubella, which together with Strangospora pinicola were valuable founds in Polish orchards. In Slovak orchards, special attention should be paid to Acrocordia gemmata, Melanelixia glabra and Usnea hirta. Among interesting records in Italian orchards, Phaeophyscia hispidula and Ph. kairamoi can be mentioned.

    2014-04-01

    This paper gives an overview, in the era of regionalization, of vaccination planning and vaccine price management in the Italian National Health Service. In particular, we analyse the current National Vaccination Plan (NVP) and end with two "case studies" of the latest entries in the Italian vaccination calendar, comparing HPV and PCV vaccines, the most expensive ones in Italy at present. The present NVP put an end to the long period without official documents for vaccination planning, mainly reflecting the controversial relationships between the national and regional tiers. However, this document is not really useful for planning from the health professionals' point of view, lacking epidemiological information. Thorough systematic assessment of the new, expensive vaccines is becoming a real priority in the light of current financial difficulties. In this perspective, the two examples discussed have given different results so far, starting from a heterogeneous situation of potential market competition.

    Every year around 50 millions Mg solid waste are incinerated in Europe. Large differences exist in different regions, mainly regarding energy recovery, flue gas treatment and management of solid residues. This paper aims to identify and quantify those differences, providing a Life Cycle Assessment...... of two incinerator systems that are representative of conditions in Northern and Southern Europe. The two case studies are Aarhus (Denmark) and Milan (Italy). The results show that waste incineration appears more environmentally friendly in the Danish case than in the Italian one, due to the higher...... energy recovery and to local conditions, e.g. substitution of electricity and heat in the area. Focusing on the incineration process, Milan incinerator performs better than Aarhus, since its upstream impacts (related to the production of chemicals used in flue gas cleaning) are more than compensated...

    This report is aimed at presenting the results of the energy efficiency evolution in Italy for the 1970-1992 period Results come from the data-base developed under the SAVE/EnR project on `Cross countries comparison on energy efficiency indicators`. In order to be comparable among countries, efforts have been made to harmonize the data collection as well as the definition and the calculation of energy efficiency indicators. Selected indicators are considered in order to illustrate the potentiality of the project (around 200 different energy efficiency indicators can be calculated and presented). Emphasis is put on the interpretation of the so-called `techno-economic indicators` as well as explanatory indicators both for the economic and techno-economic approaches. Industry, transport, tertiary, residential and transformation sectors have been analyzed.

    2012-01-01

    Full Text Available This research [1] outlines the typologies and symptoms of female alcohol addiction in Southern Italy. Among the socially existing dependencies, female alcohol addiction has its own autonomy that goes beyond the mere act of drinking. As the results of this research show, women’s drinking, which is often considered deviant, ridiculed (and stereotyped by society, is instead a form of self-expression, support, achievement and maintenance of identity. On this basis, telling and referring to the lives of women, giving them leave to speak, means being aware of the need of listening continuously to the silent shout of daily life in relation to the consequent social dynamics, keeping in mind the evident individual roots of social crisis.

    A survey based on a statistically representative sample of 5000 dwellings distributed in 200 administrative districts has been planned in Italy to evaluate exposure indoors. Knowledge of the distribution of radon concentration and gamma absorbed doses in air allows a determination of the average risk to which the population is subjected and of the number of dwellings exceeding a given action level. Radon concentration is monitored for two 6 month periods, while the [gamma] exposure is measured for only one semester. Duplicate radon measurements are performed by using etched track detectors (typically LR-115 II type and CR-39). The survey is carried out at district level by local laboratories, under the coordination of the two central institutions ENEA/DISP and ISS. The overall structure of the survey is described together with the first results obtained. (author).

    The national seismic network of Italy (Rete Sismica Nazionale, RSN) run by Istituto Nazionale di Geofisica e Vulcanologia (INGV) consists of more than 400 seismic stations connected in real time to the institute data center in order to locate earthquakes for civil defense purposes. A critical issue in the performance of a network is the characterization of site condition at the recording stations. Recently INGV has started addressing this subject through the revision of all available geological and geophysical data, the acquisition of new information by means of ad-hoc field measurements and the analysis of seismic waveforms. The main effort is towards building a database, integrated with the other INGV infrastructures, designed to archive homogeneous parameters through the seismic network useful for a complete site characterization, including housing, geological, seismological and geotechnical features as well as the site class according to the European and Italian building codes. Here we present the ongoing INGV activities.

    Field ethnobotanical survey was undertaken for the period of 2002-2003 in the Tyrrhenian part of the Basilicata region of southern Italy. Data of 56 species of plants belonging to 29 families where gathered through interviews; among the species, 47 are used in human therapy, 6 as insect repellents, 15 in veterinary medicine, 1 for its ichthyotoxic properties and 3 for magic therapeutic purposes. The most important findings in ethnomedicine relate to Nasturtium officinale (renal colic, liver diseases), Foeniculum vulgare subsp. piperitum (mouth ulcers), Leopoldia comosa (toothache, headache), Micromeria graeca subsp. graeca (coughs) and Ceterach officinarum (malaria), while in the ethnoveterinary field, we have Pteridium aquilinum (wolf bites) and Spartium junceum (fractures of animal limbs).

  16. [Agriculture in Italy nowadays: ancient risks and emerging diseases].

    Since produce food using the environment, agricultural activities are fundamental for human and environmental health. They expose workers to all the known health and safety risks: pesticides and other chemicals, noise, vibrations, solar radiation, climate changes, organisational factors, biological, biomechanical and allergic risks. Also the risk of accidents is very relevant. Apart for these well-known risks, new risks and diseases are emerging, such as biological risk from vectors, modulated by climate changes, or risks related to new production modalities, such as the cases of peripheral neuropathy observed in pig butchers. The risks can affect particularly vulnerable groups, such as seasonal, temporary workers and migrants. Currently, in Italy, an increase in reports of occupational diseases in the sector is being observed, in particular for musculoskeletal disorders. Such increase finds an explanation not in a worsening situation at the workplace but in an increasing attention for rural workers accompanied by an increased reporting of occupational diseases.

    Bruno Rossi (1905-1993), one of the giants of 20th-century physics, was a pioneer in cosmic-ray physics and virtually every other aspect of high-energy astrophysics. His scientific career began at the University of Florence in 1928 and continued at the University of Padua until 1938, when the Fascist anti-Semitic racial laws were passed in Italy. He was dismissed from his professorship and was forced to emigrate, as described in unpublished letters and documents that display the international character of physics and physicists. His young bride Nora Lombroso, his love of physics, and the solidarity of the physics community gave him the courage to begin a new life in Copenhagen, Manchester, and in the New World at the University of Chicago, Cornell University, Los Alamos, and after the Second World War at the Massachusetts Institute of Technology where he became the center of a worldwide research network.

    A new AMS system has been installed at Center for Isotopic Research on Cultural and Environmental Heritage (CIRCE) in Caserta/Italy. It was built by National Electrostatics Corp. Middleton, WI/USA, and arrived at CIRCE in the middle of January 2005; the installation and the acceptance tests were completed at the end of February 2005. At first, the system is intended for Radiocarbon AMS; for future Al and Be AMS only minor upgrades are needed and the magnets are designed to bend heavy isotopes like Uranium. Concerning Radiocarbon AMS, the first measurements of unknown samples, prepared in the internal preparation laboratory, already yielded results of high precision and {sup 14}C dating is in full swing.

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
