    Nosenzo A


    Full Text Available Chestnut (Castanea sativa L. coppice stands currently cover about 195.000 ha of Piedmont (North-Western Italy surface, corresponding to 22.4 % of the overall forested area in the region. Most of these forest stands are usually older than the typical rotation period. As a consequence from these stands timber assortments with a higher value could be obtained. The purpose of this study is to assess the amount of timber assortments and to propose a sorting methodology based on measurements on standing trees within these chestnut stands.Five study areas were selected in the Susa Valley, where forest measurements were realized within sampling plots. Timber assortments obtainable from each coppice shoot were then determined by means of the Bitterlich’s relascope. More than 1.000 timber logs were measured. The data elaboration allowed to assess the timber assortment production of the investigated stands. The proposed methodology makes it possible to better exploit timber assortments. In fact, while usually the whole production from chestnut coppices is directly destined to secondary products, the subdivision into assortments could result in a 20 % of products with higher commercial value. It is important to notice that within these stands no tending operation is currently realized. The definition of qualitative features to classify timber assortments can provide useful suggestions on the main yield targets that could be reached through silvicultural management.

  2. The Lyon-Turin high-speed rail: the public debate and perception of environmental risk in Susa Valley, Italy. (United States)

    Marincioni, Fausto; Appiotti, Federica


    When the construction of the Lyon-Turin segment of the new European high-speed rail network was first publicly announced at the beginning of the 1990 s, it immediately found fierce opposition from the inhabitants of Susa Valley, Italy, one of the areas to be cut across by such infrastructure. At issue were the project's potential environmental impact and its consequences on public health. This study intends to clarify environmental risk perception and public debate between the national government, local advocacy groups, and the inhabitants of Susa Valley. Two major phases of public reaction were identified: (1) an initial rebellious period of no real dialog among the project's major stakeholders (exemplified by the popular "No TAV" [No High Speed Train] movement), followed by (2) a yielding period of intense multilateral negotiations centered on the activities of the "Lyon-Turin Environmental Observatory." The results of a qualitative cross analysis of the residents' perception of the proposed high-speed rail revealed that public acceptance of risk in Susa Valley was influenced by the characteristics of hazards perceived by the residents and by the communicative approach used by the project's various stakeholders. It also emerged that early dialog among all the parties involved was critical in forming a personal viewpoint on risk, which, once consolidated, defied new information and perspectives. Likely, a greater and earlier care taken by the other stakeholders to inform and consult the local population about the railway would have greatly eased the public debate.

  3. Geodiversity and geohazards of the Susa Valley (W-Alps, Italy): combining scientific research and new technologies for enhanced knowledge and proactive management of geoheritage in mountain regions (United States)

    Giardino, Marco; Bacenetti, Marco; Perotti, Luigi; Giordano, Enrico; Ghiraldi, Luca; Palomba, Mauro


    Mountain regions have a range of geological and geomorphological features that make them very attractive for tourism activities. As a consequence, increased human "pressure" causes impacts on geoheritage sites and higher geomorphological risks. These effects are magnified by active geomorphic processes characterizing mountains areas, highly sensitive to climate change. In term of "human sensitivity", several sociological surveys have shown that "perceived risk", not "real risk", influences people's behavior towards natural hazards. The same approach can be applied to geodiversity and geoheritage. Based on these assumptions, we considered the possible strategic roles played by diffusion of scientific research and application of new technologies: 1) to enhance awareness, either of geodiversity or environmental dynamics and 2) to improve knowledge, both on geoheritage management and natural risk reduction. Within the activities of the "ProGEO-Piemonte Project" (Progetti d'Ateneo 2011, cofunded by Universita? degli Studi di Torino and Compagnia di San Paolo Bank Foundation), we performed a systematic review of geodiversity and natural hazards information in the Piemonte Region (NW-Italy). Then we focused our attention on the Susa Valley, an area of the Western Alps where the geoheritage is affected by very active morphodynamics, as well as by a growing tourism, after the 2006 winter Olympics. The Susa Valley became one of the 9 strategic geothematic areas have been selected to represent the geodiversity of the Piemonte region, each characterized by high potential for enhancement of public understanding of science, and recreation activities supported by local communities. Then we contributed to the awareness-raising communication strategy of the "RiskNat project" (Interreg Alcotra 2007-2013, Action A.4.3) by synthesizing geoscience knowledge on the Susa Valley and information on slope instabilities and models/prevention measures/warning systems.

  4. Multidisciplinary approach to the Clot Brun large slope instability (Susa Valley, Italian NW-Alps) (United States)

    Giardino, M.; Fontan, D.; Ambrogio, S.; Dematteis, A.; Nervo, B.; Walkate, J.; Fratianni, S.


    The Clot Brun slope is affected by a large deep-seated gravitational deformation and by other correlated and non-correlated minor gravitational instabilities (rock falls and debris flows). The activation of the slope instabilities may involve several lifelines along the Susa Valley (motorway, railway, hydro-electrical tunnel, ...) as well as some small villages with sites of historical and architectural interest. In order to develope effective protection measures of the affected structures, a multidisciplinary study of the Clot Brun large slope has been carried out including geomorphology, structural geology, hydrogeology and pedology through the application of up-to-date scientific methodologies (geomorphological mapping of the surface deformation markers, structural geology analisys carried out with climbing technics, pedological profile studies along the main active sectors of the slope, 3D computer modelling of the deformed rock masses and general slope characteristics). The data have been collected in modular form and organized in a geo-database. Output geothematic maps have been produced both at 1:10000 and 1:5000 scales. GIS methodologies have been applied for the analisys and interpretation of long-term slope dynamics and to evaluate possible impulsive instability, failure and related hazards.

  5. Nucleation and growth of new particles in Po Valley, Italy

    Full Text Available Aerosol number distribution measurements are reported at San Pietro Capofiume (SPC station (44°39' N, 11°37' E for the time period 2002–2005. The station is located in Po Valley, the largest industrial, trading and agricultural area in Italy with a high population density. New particle formation was studied based on observations of the particle size distribution, meteorological and gas phase parameters. The nucleation events were classified according to the event clarity based on the particle number concentrations, and the particle formation and growth rates. Out of a total of 769 operational days from 2002 to 2005 clear events were detected on 36% of the days whilst 33% are clearly non-event days. The event frequency was high during spring and summer months with maximum values in May and July, whereas lower frequency was observed in winter and autumn months. The average particle formation and growth rates were estimated as ~6 cm−3 s−1 and ~7 nm h−1, respectively. Such high growth and formation rates are typical for polluted areas. Temperature, wind speed, solar radiation, SO2 and O3 concentrations were on average higher on nucleation days than on non-event days, whereas relative and absolute humidity and NO2 concentration were lower; however, seasonal differences were observed. Backtrajectory analysis suggests that during majority of nucleation event days, the air masses originate from northern to eastern directions. We also study previously developed nucleation event correlations with environmental variables and show that they predict Po Valley nucleation events with variable success.

  6. Soapstones from the Ossola Valley (Piedmont, northern Italy) (United States)

    Cavallo, Alessandro


    The term "soapstones" is referred to "soft", easily workable stones (talc and/or chlorite-rich metamorphic rocks, deriving from mafic - ultramafic protoliths), typically used for jars, pots and pipes. The term has been also improperly extended to "harder" varieties (e.g. serpentinites), mostly suitable for roof slabs and millstones. These rocks are characterized by easy workability and fire-resistance, and they had a remarkable historical, artistic and archaeological importance. In the Ossola region (Piedmont, northern Italy), the soapstones are traditionally known as "Pietra Laugera", "Pietra Lavizzaria" or "Pietra Ollare", and represent one of the oldest stony raw materials used since the Bronze Age (archaeological find in the Toceno surroundings, Vigezzo Valley). The discovery of archaeological handmade objects in the surroundings of the Ossola Valley testifies a massive use of green stones during the I century A.D., even for cinerary urns and grave outfits. A lot of two handles pots and milk vessels date back to the Middle Ages, as well as millstones and water pipes. Artistic and ornamental uses are documented in churches and civil buildings: for example, columns, capitals, pilasters and bas-reliefs (Sacro Monte del Calvario chapels, now UNESCO heritage, and the Collegiale Church in Domodossola) as well as fireplaces (e.g. Silva Palace in Domodossola), sculptures, ornaments and balustrades. The productivity reached the top in the XIX century and stopped in the twenties; nowadays the extraction occurs only in the Loana Valley, with a very limited production. The historical soapstones derive both from ophiolitic complexes (Antrona and Zermatt-Saas Zones) and from the ultramafic complexes within the Orselina-Moncucco-Isorno Zone, Monte Leone nappe and Sesia-Lanzo Zone. The historical quarries are usually small (even erratic boulders), and scattered over many lateral valleys, such as Brevettola, Antrona, Bognanco and Loana. A total of 52 representative samples were

    Full Text Available The project of the new station of Torino Porta Susa is the project of a huge urban public space, where the station, conceived as an urban gallery, becomes a real street, a “passage”, a new kind of urbanity shape for the future city. The railway station’s transparent volume - a 385 m (the length of the TGV long steel and glass tunnel, 30 m. width, with a variable height compared to the outdoor street level (between 12 and 3 m at the height of the cover - is proposed as a modern reinterpretation of the nineteenth century’s urban galleries and the great historical station’s halles, as well as a kind of symbolic building. Symbol of movement, of the travel universe and the presence of the transportation universe in the contemporary city, urban simulacrum of the object train disappeared from the urban scene below the future Central Spine. The sinuous movement of the tunnel follows the flows of urban pedestrians from the city towards the different transportation modes presents at various levels (national and international lines AV, regional lines, subways, taxis ... emphasizing with its lowering the presence of the big void inside of the underground subway station, about 20 meters deep. The gallery, oriented north-south, folds with its internal pedestrian paths to bring natural light and the sky of Turin, to the quays of trains (at an altitude of -10 m and the Subway (which share -20, transformed so’ in a sort of urban sidewalks. The fast rhythm of the structure of arches with step 360 cm. is marked by the presence of numerous openings along the longitudinal development of the gallery, which is crossed by three transversal passages inside the gallery and is bounded by two others on the north and south of the lot, connecting the city from east to west at street level in continuity with pre-existing axes. The presence of these transversal passages accentuates the urban value of the Spina which was to re-connect the two sides of the city until

  10. A didactical geological path in Val Rosandra valley (Trieste - Italy) (United States)

    Godini, E.


    Introduction: the presented field work is aimed to involve a group of 15-17 years old students in building a simplified geomorphological and geological model of Val Rosandra valley, by means of guided observations and data collection. The didactical path may be changed according to age, skills or particular needs of students and meteorological conditions; at best, 4-5 hours are needed for the complete field trip. Some ideas about sedimentary rocks, folding and faulting, and the principle of superposition could be useful as pre-concepts, but "could" also be learnt during the experience. Organization: students will be divided into small groups (3-4 students each), possibly with different roles within the group (topographer, photographer, draftsman, geologist, geomorphologist,…). Needed materials for each group: notebook, paper, pencil, rubber, photo camera, ruler, compass, scale 10.000 topographic map, stratigraphic chart, altimeter, diluted hydrochloric acid. Observation points: 1. Bagnoli spring, marl outcrop 2. Bagnoli village, towards the "heart-shaped quarry" 3. By the river, in the lower part of the valley 4. Moccò lookout 5. Marl outcrop, from Moccò to the old railway 6. From the old railway, above the valley 7. By the river, in the upper part of the valley The field work: at first, students will be guided to observe and take notes of the main morphological characteristics, so that the different "observation points" will be drawn on the map, with the help of compass. An easily recognizable system of faults cuts the valley; a "V" profile is visible in the lower part of the valley (a small amount of sediment is present), while a calcareous gorge is evident in the upper valley, where there are no sediments (observation points 3, 4, 6 and 7). The morphology is asymmetric, due to the different arrangement of strata in the left and right side of the valley: right side shows big "steps" (horizontal arrangement of strata), left side is rich in slopes (tilted

  11. Human biomonitoring for Cd, Hg and Pb in blood of inhabitants of the Sacco Valley (Italy

    Directory of Open Access Journals (Sweden)

    Sonia D'Ilio


    Full Text Available INTRODUCTION. The Sacco Valley (Lazio, Italy is characterized by high density population and several industrial chemical productions that during the time had led to a substantial amount of by-products. The result was a severe environmental pollution of the area and in particular of the river Sacco. In 1991, the analysis of water and soils samples of three industrial landfills revealed the presence of organochlorine compounds and heavy metals. A research project named "Health of residents living in Sacco Valley area", coordinated by the regional Department of Epidemiology, was undertaken and financed to evaluate the state of health of the population living near those polluted areas. MATERIALS AND METHODS. Cd, Hg and Pb were quantified in 246 blood samples of potentially exposed residents of the Sacco Valley by quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS. RESULTS. Individuals who agreed to be sampled did not exhibit high levels of the elements. The distance from the river does not seem to be directly connected with the elements levels in blood. The contribution of these contaminants to the total intake due to ingestion of food was difficult to evaluate. The unclear trend of data would require a characterization of the polluted site with environmental sampling of different matrices.

  12. Three-dimensional seismo-tectonics in the Po Valley basin, Northern Italy (United States)

    Turrini, Claudio; Angeloni, Pamela; Lacombe, Olivier; Ponton, Maurizio; Roure, François


    The Po Valley (Northern Italy) is a composite foreland-foredeep basin caught in between the Southern Alps and Northern Apennine mountain belts. By integrating the 3D structural model of the region with the public earthquake dataset, the seismo-tectonics of the basin is shown at different scales of observation. The three-dimensional geo-volume is used to review the seismicity around the region and validate the structure-earthquake association for such a complex tectonic framework. Despite the overall uncertainty due to the original data distribution-quality as well as the crustal scale model dimension, the direct correlation between structures and seismicity a) confirms the Po Valley region as an active tectonic system and b) allows the whole structural architecture to be revised by a unique three-dimensional perspective and approach. This study also indicates that 3D methodology is a powerful tool for better understanding of highly complex seismo-tectonic situations at both regional and local scales.

  13. Debris flow hazard assessment in the Langtauferer valley, South Tyrol, Northern Italy. (United States)

    Reichegger, Martina; Busetto, Daniela; Glade, Thomas; Zischg, Andreas


    Debris flows pose a significant threat to the environment and society in numerous alpine valleys. Various approaches exist to assess the respective hazards in order to delineate regions, which are prone to a given magnitude and frequency of debris flows. This research aims to couple the hydraulic FLO-2D model with a sediment assessment model in order to identify endangered settlement areas situated on the torrential fans. A hazard assessment for debris flows was conducted on seven torrential fans in the Langtauferer valley, South Tyrol, northern Italy. The debris flow process was simulated by the hydraulic FLO-2D computer model for return periods 30, 100 and 300 years. The main input parameters had to be determined previously: water runoff was calculated by a rainfall-runoff model and the amount of sediment entrainable by debris flows was estimated in the field. For validation the results were compared with historical debris flow data. A classification in high and very high debris flow hazard based on maximum flow depths showed that none of the settlement areas are affected by the highest hazard class. Comparing the results with historic events, the chosen model inputs water runoff and amount of sediment appear plausible and therefore applicable in planning strategies.

  14. Enhanced toxicity of aerosol in fog conditions in the Po Valley, Italy (United States)

    Decesari, Stefano; Sowlat, Mohammad Hossein; Hasheminassab, Sina; Sandrini, Silvia; Gilardoni, Stefania; Facchini, Maria Cristina; Fuzzi, Sandro; Sioutas, Constantinos


    While numerous studies have demonstrated the association between outdoor exposure to atmospheric particulate matter (PM) and adverse health effects, the actual chemical species responsible for PM toxicological properties remain a subject of investigation. We provide here reactive oxygen species (ROS) activity data for PM samples collected at a rural site in the Po Valley, Italy, during the fog season (i.e., November-March). We show that the intrinsic ROS activity of Po Valley PM, which is mainly composed of biomass burning and secondary aerosols, is comparable to that of traffic-related particles in urban areas. The airborne concentration of PM components responsible for the ROS activity decreases in fog conditions, when water-soluble species are scavenged within the droplets. Due to this partitioning effect of fog, the measured ROS activity of fog water was contributed mainly by water-soluble organic carbon (WSOC) and secondary inorganic ions rather than by transition metals. We found that the intrinsic ROS activity of fog droplets is even greater (> 2.5 times) than that of the PM on which droplets are formed, indicating that redox-active compounds are not only scavenged from the particulate phase, but are also produced within the droplets. Therefore, even if fog formation exerts a scavenging effect on PM mass and redox-active compounds, the aqueous-phase formation of reactive secondary organic compounds can eventually enhance ROS activity of PM when fog evaporates. These findings, based on a case study during a field campaign in November 2015, indicate that a significant portion of airborne toxicity in the Po Valley is largely produced by environmental conditions (fog formation and fog processing) and not simply by the emission and transport of pollutants.

  15. A new finding of Salamandra lanzai in the Upper Sangone Valley (NW Italy marks the species' most disjunct population (Amphibia: Urodela: Salamandridae

    Directory of Open Access Journals (Sweden)

    Giulia Tessa


    Full Text Available The presence of Salamandra lanzai was confirmed for the Upper Sangone Valley (Turin Province, NW Italy, within the Parco Naturale Orsiera Rocciavré. The species attribution was further supported by morphological and genetic (16S analysis and represents the north-eastern most limit of the species’ distribution. This salamander was so far known only for a few major alpine valleys of Italy (Po, Pellice, and Germanasca Valleys, and France (Guil Valley. The new finding is especially interesting since it is separated from its closest known locality by about 15 km. For such a reason this population needs to be carefully managed.

  16. Possible future lakes resulting from continued glacier shrinkage in the Aosta Valley Region (Western Alps, Italy) (United States)

    Viani, Cristina; Machguth, Horst; Huggel, Christian; Godio, Alberto; Perotti, Luigi; Giardino, Marco


    Aosta Valley (NW-Alps, Italy) is the region with the largest glaciarized area of Italy (133.73 km2). Like the other alpine regions it has shown a significant glacier retreat starting from the end of the Little Ice Age (LIA, ca. 1850 AD), by losing about 60% of its glaciarized area. As a direct consequence of glacier shrinkage, within glacially-sculpted landscapes, glacier-bed overdeepenings become exposed, offering suitable conditions for glacier lakes formation. In the Aosta Valley region, about 200 glacier lakes have been recognized in different time periods within LIA maximum extent boundaries, mainly dammed by bedrock landforms. With respect to human activities, glacier lakes represent both opportunities (e.g. Miage lake for tourism) and risks (e.g. outburst flood of the Gran Croux lake above Cogne in August 2016) in such a densely populated and developed region. The objective of this contribution is to assess locations of possible future glacier lakes in the Aosta Valley by using the GlabTop2 model (Glacier Bed Topography model version 2). Understanding where future lakes will appear is of fundamental importance for the identification of potential hazards and the interpretation of conditioning factors and dynamics. We first assessed ice thickness and consequently glacier bed topography over large glaciated areas of the region, by using both glaciers outlines related to 1999 (provided by the GlaRiskAlp project) and the regional DEM of 1990 (provided by the Aosta Valley Region) as input data. We performed several runs by varying different input parameters (e,g.: pixel size and basal shear stress). Then we compared modelled results on selected test glaciers (Rutor and Grand Etrèt) with available GPR data. As a validation, we also carried out a GPR survey during summer 2016 on the central area of Indren Glacier (Monte Rosa massif) where GlabTop2 shows the presence of a possible subglacial overdeepening morphology. We found that ice thickness and consequently the

  17. The importance of inherited structures in slope evolution: the Ridnaun Valley case, Italy (United States)

    Zorzi, L.; Flaim, L.; Massironi, M.; Genevois, R.; Stead, D.


    The south facing slope of the Ridnaun Valley (South Tyrol, Italy) comprises the crystalline units belonging to the Austoalpine Nappe of the Alpine orogenic wedge and shows evidence of quaternary gravitational evolution which is highly dependent on the interaction between the slope trend and the brittle/ductile structural setting. The slope valley is incised within the paragneiss rocks of the Oetztal - Stubei Unit and the micaschists of the Schneeberg Unit. These two units are separated by a NNW gentle dipping tectonic contact, which obliquely intersects the E-W slope, and is characterized by multiple ultracataclasitic layers that follow the regional low angle north-dipping schistosity. Folds with sub-horizontal E-trending axes induce a change in the dip direction of the regional schistosity from N dipping (unfavorable to the slip) to SE dipping (favorable to the slip). NNE-SSW and N-S trending faults, having a mean thickness of incoherent fault breccias of 1 m, affect the entire slope. These along with the folds and the ultracataclastic layers, have significant influence on rock mass mechanical properties and on mechanisms and timing of the observed gravitational phenomena. Field work and ALS-HRDEM analysis has revealed different gravitational movements along the slope. A fully evolved gravitational collapse, having the features of a Rock Avalanche (RA), characterizes the central part covering an area of about 2.4 km2; whereas to the east and west of the RA, deep seated gravitational slope deformations (DSGSDs) still affect the slope. An ongoing gravitational deformation is apparent in the uphill sections of the slope, next to the crown area of the RA. PS and DS - SAR interferometry data (provided by the Geological Survey of the Autonomous Province of Bolzano, Italy), testify an ongoing movement on both the DSGSDs bordering the RA, highlighting a most unstable area at the western sector. The heterogeneous behavior of the slope is most likely controlled by the

  18. Palaeoseismology related to the displaced Roman archaeological remains at Egna (Adige Valley, northern Italy) (United States)

    Galadini, Fabrizio; Galli, Paolo


    A Roman building of the 1st century AD has been discovered during archaeological excavations in the village of Egna (Adige Valley, NE Italy) on the distal portion of a large Holocene alluvial fan. The remnants of the walls appear to have been displaced by shear planes having oblique movement with a minor dextral component. Subsequent palaeoseismological analyses have been performed through the excavation of seven trenches inside the ancient building; all of the trenches showed that the sedimentary units have also been displaced. The deepest trench (>6 m) also showed a sudden increase of the vertical offset in the lower portion of the sedimentary succession, therefore suggesting a displacement event which preceded the Roman age event. Archaeological dating of the numerous remains and radiocarbon dating of organic silt, bone and wood fragments permitted the reconstruction of the site history. The most recent event occurred around the middle of the 3rd century AD and was responsible for the displacement, destruction and consequent abandonment of the site, whereas the older event occurred not much after 2581-2197 BC. The alluvial fan deposition occurred after the 3rd century AD (0.60-1.5 m of historical deposits) and the intense urbanisation of the site hid all surficial traces of the 3rd century AD displacement. Geomorphological surveys and drilling data (four boreholes up to 20 m deep) exclude the possibility that the observed displacements were caused by gravity-driven phenomena. It is much more likely that they are the expression of fault activity, possibly related to the Giudicarie fault system. While moderate seismic activity and evidence of recent tectonics have been reported for the southern sector of this structural system, the present palaeoseismological analysis indicates that the northern sector may have also caused earthquakes which resulted in significant surficial deformation.

  19. Assessment of long-term erosion in a mountain vineyard, Aosta Valley (NW Italy) (United States)

    Biddoccu, Marcella; Zecca, Odoardo; Barmaz, Andrea; Godone, Franco; Cavallo, Eugenio


    Tillage and chemical weeding are common soil management techniques adopted in mountain vineyards, with high slope gradient, to maintain bare soil. Both techniques exposes the soil to degradation, favoring runoff and soil losses, that may cause relevant on-site and off-site damage. Steep mountain slopes makes optimum conditions for grape-growing. In the mountain region of Aosta Valley, NW Italy, the vineyards were, in the past, traditionally grown on terraces supported by dry stone walls. Since the 1960s the plantation of vines in the direction of the slope became more and more widespread, also on very steep slopes. Generally, no particular measure to channel and control surface water is adopted in this area due to the low rainfall (560 mm/year). Nevertheless in steep mountain slope rainfall events can cause important runoff erosion. In order to evaluate the long-term effect of vineyard management techniques on soil erosion, a study was carried out on a mountain slope vineyard located near Aosta, at about 900 m above the sea level. The vineyard was planted at the end of 1960s and is managed by the Institut Agricole Régional. The rows are accommodated oriented along the slope, which is about 45%. The inter-rows' soil management of the vineyard included chemical weeding and, in first year after plantation, the adoption of irrigation (by fixed overhead sprinklers) and hilling-up/taking-out the soil around the vine plants, to protect them from cold weather. The long-term soil erosion rate was determined adopting the technique of botanical benchmark (Casalí et al.,2009). The grafting callus was used as a marker to identify the paleo-surface at the time of planting. A detailed topographic survey was carried out to determine the present surface of the vineyard while the current position of the grafting callus was recorded for a number of plants. The original position of the callus was estimated by data obtained by farmers and by a survey on reference vineyards. Two

  20. GIS-based modeling of debris flow processes in an Alpine catchment, Antholz valley, Italy (United States)

    Sandmeier, Christine; Damm, Bodo; Terhorst, Birgit


    Debris flows are frequent natural hazards in mountain regions, which seriously can threat human lives and economic values. In the European Alps the occurrence of debris flows might even increase with respect to climate change, including permafrost degradation, glacier retreat and variable precipitation patterns. Thus, detailed understanding of process parameters and spatial distribution of debris flows is necessary to take appropriate protection measures for risk assessment. In this context, numerical models have been developed and applied successfully for simulation and prediction of debris-flow hazards and related process areas. In our study a GIS-based model is applied in an alpine catchment to address the following questions: Where are potential initiating areas of debris flows? How much material can be mobilized? What is the influence of topography and precipitation? The study area is located in the Antholz valley in the eastern Alps of Northern Italy. The investigated catchment of the Klammbach creek comprises 6.5 km² and is divided into two sub-catchments. Geologically it is dominated by metamorphic rock and altitudes range between 1310 and 3270 m. In summer 2005 a debris flow of more than 100000 m³ took place, originating from a steep, sparsely vegetated debris cone in the western part of the catchment. According to a regional study, the lower permafrost boundary in this area has risen by 250 m. In a first step, during a field survey, geomorphological mapping was performed, several channel cross-sections were measured and sediment samples were taken. Using mapping results and aerial images, a geomorphological map was created. In further steps, results from the field work, the geomorphological map and existing digital data sets, including a digital elevation model with 2.5 m resolution, are used to derive input data for the modeling of debris flow processes. The model framework ‘r.debrisflow' based on GRASS GIS is applied (Mergili, 2008*), as it is

  1. Evidence for ambient dark aqueous SOA formation in the Po Valley, Italy

    Directory of Open Access Journals (Sweden)

    A. P. Sullivan


    Full Text Available Laboratory experiments suggest that water-soluble products from the gas-phase oxidation of volatile organic compounds can partition into atmospheric waters where they are further oxidized to form low volatility products, providing an alternative route for oxidation in addition to further oxidation in the gas phase. These products can remain in the particle phase after water evaporation, forming what is termed as aqueous secondary organic aerosol (aqSOA. However, few studies have attempted to observe ambient aqSOA. Therefore, a suite of measurements, including near-real-time WSOC (water-soluble organic carbon, inorganic anions/cations, organic acids, and gas-phase glyoxal, were made during the PEGASOS (Pan-European Gas-AeroSOls-climate interaction Study 2012 campaign in the Po Valley, Italy, to search for evidence of aqSOA. Our analysis focused on four periods: Period A on 19–21 June, Period B on 30 June and 1–2 July, Period C on 3–5 July, and Period D on 6–7 July to represent the first (Period A and second (Periods B, C, and D halves of the study. These periods were picked to cover varying levels of WSOC and aerosol liquid water. In addition, back trajectory analysis suggested all sites sampled similar air masses on a given day. The data collected during both periods were divided into times of increasing relative humidity (RH and decreasing RH, with the aim of diminishing the influence of dilution and mixing on SOA concentrations and other measured variables. Evidence for local aqSOA formation was only observed during Period A. When this occurred, there was a correlation of WSOC with organic aerosol (R2 = 0.84, aerosol liquid water (R2 = 0.65, RH (R2 = 0.39, and aerosol nitrate (R2 = 0.66. Additionally, this was only observed during times of increasing RH, which coincided with dark conditions.

    Arvani, Barbara; Pierce, R. Bradley; Lyapustin, Alexei I.; Wang, Yujie; Ghermandi, Grazia; Teggi, Sergio


    In this work, the new 1 km-resolved Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm is employed to characterize seasonal PM10 - AOD correlations over northern Italy. The accuracy of the new dataset is assessed compared to the widely used Moderate Resolution Imaging Spectroradiometer (MODIS) Collection 5.1 Aerosol Optical Depth (AOD) data, retrieved at 0.55 μm with spatial resolution of 10 km (MYD04_L2). We focused on evaluating the ability of these two products to characterize both temporal and spatial distributions of aerosols within urban and suburban areas. Ground PM10 measurements were obtained from 73 of the Italian Regional Agency for Environmental Protection (ARPA) monitoring stations, spread across northern Italy, during a three-year period from 2010 to 2012. The Po Valley area (northern Italy) was chosen as the study domain because of its severe urban air pollution, resulting from it having the highest population and industrial manufacturing density in the country, being located in a valley where two surrounding mountain chains favor the stagnation of pollutants. We found that the global correlations between the bin-averaged PM10 and AOD are R2 = 0.83 and R2 = 0.44 for MYD04_L2 and for MAIAC, respectively, suggesting a greater sensitivity of the high-resolution product to small-scale deviations. However, the introduction of Relative Humidity (RH) and Planetary Boundary Layer (PBL) depth corrections allowed for a significant improvement to the bin-averaged PM - AOD correlation, which led to a similar performance: R2 = 0.96 for MODIS and R2 = 0.95 for MAIAC. Furthermore, the introduction of the PBL information in the corrected AOD values was found to be crucial in order to capture the clear seasonal cycle shown by measured PM10 values. The study allowed us to define four seasonal linear correlations that estimate PM10 concentrations satisfactorily from the remotely sensed MAIAC AOD retrieval. Overall, the results show that the high

    Papotti, D


    Landscapes are both a synthesis and an expression of national, regional and local cultural heritages. It is therefore very important to develop techniques aimed at cataloguing and archiving their forms. This paper discusses the LDL (Landscape Digital Library) project, a Web accessible database that can present the landscapes of a territory with documentary evidence in a new format and from a new perspective. The method was tested in a case study area of the river Po valley (Northern Italy). The LDL is based on a collection of photographs taken following a systematic grid of survey points identified through topographic cartography; the camera level is that of the human eye. This methodology leads to an innovative landscape archive that differs from surveys carried out through aerial photographs or campaigns aimed at selecting "relevant" points of interest. Further developments and possible uses of the LDL are also discussed.

  4. Italy. (United States)


    For "Background Notes" on Italy, the U.S. State Department, Bureau of Public Affairs, covers geography, people, history, government, politics, economy, defense and foreign relations. 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.

  5. Analysis of the protective function of forests: a study case in the Aosta Valley (Italy

    Directory of Open Access Journals (Sweden)

    Meloni F


    Full Text Available The Aosta Valley is a densely populated mountainous area in which interaction between natural hazards and human activities has been shaping the development of settlements and infrastructure for centuries. The forests cover almost 30% of the totals surface (326088 ha and have been providing protection against avalanches, rock fall and floods. During the past decades, the importance of the forests as a protection against natural hazards in Aosta Valley, and more in general in the whole European Alps, has increased. Remote valleys, that were formerly avoided during winter, are now expected to be permanently accessible for tourists, settlements have been spreading into areas that were considered unsafe and transports crossing the Alps have strongly increased. The forests that directly protect settlements, railways, main roads and socio-economical infrastructures represent a priority in the forest and landscape management at the regional scale since the direct prote ctive role of forests needs to be efficiently and continuously effective. Protective forest mapping is the first step of a sustainable long-term silvicultural management. Starting from a digital terrain model (DTM in a raster format with a spatial resolution of 10 m, other numerical maps and forest information, a regional map (1:10000 of the forests that play a direct protection has been developed. The forests that potentially play a protective role and the forests that play a potentially direct protective role cover represents respectively 79.8% and 42.7% of the forest cover.

    Full Text Available An analysis on the alpine spatial factors was carried out in the area of Kranjska gora and the Upper Sava valley, in the NW corner of Slovenia (Yugoslavia. As a part of a similar study Austrians and Italians, at their side of the border, ther research focused on future regional development. The so called "Three Border Area", in the above-mentioned countries, candidates for the winter olympics in 1998 and in general seek cross-border cooperation. The mountainous region of the Julian Alps here is separated from another mountainous and border strech of the Karawanks by the deep glacial river valley of the river Sava. The central place within the valley is Kranjska Gora — a famous winter šport center. World cup alpine skiing races and ski-jumping competitions (Planica take place here every year. The past post-war period were not very much in favour of developing tourism in general. That is why many inhabitants of the Upper Sava Valley decided to abandon agriculture and look for jobs in the governmentaly supported steel mills of the communal center of Jesenice. Daily migration accures today in both directions: man from the area migrate to the industry, woman from the above-mentioned town travel daily the same distance to work in hotels. Lately a couple of hundred inhabitants found jobs also in the nearby employment centers of Carinthia and Friuli-Venezia Giulia. Future complex regional development in the area of the bordering countries of Italy, Austria and Yugoslavia can be supported in the part of Slovenia with the tradition of mountaineering and ski jumping as well as vvith an international tradition in hosting guests from distantplaces and vvith the tradition of organizing sporting events.

  8. Ethnobotanical survey of wild food plants traditionally collected and consumed in the Middle Agri Valley (Basilicata region, southern Italy). (United States)

    Sansanelli, Sabrina; Ferri, Maura; Salinitro, Mirko; Tassoni, Annalisa


    This research was carried out in a scarcely populated area of the Middle Agri Valley (Basilicata region, southern Italy). The aim of the study was to record local knowledge on the traditional uses of wild food plants, as well as to collect information regarding the practices (gathering, processing and cooking) and the medicinal uses related to these plants. Fifty-eight people still possessing traditional local knowledge (TLK), 74% women and 26% men, were interviewed between May-August 2012 and January 2013, using open and semi-structured ethnobotanical interviews. For each described plant species, the botanical family, the Italian common and folk names, the plant parts used, the culinary preparation and, when present, the medicinal use, were recorded and the relative frequency of citation index (RFC) was determined. The 52 plant species mentioned by the respondents belong to 23 botanical families, with Asteraceae (12 plants) and Rosaceae (7 plants) being most frequently cited. The species with the highest RFC index is Cichorium intybus L. (0.95), followed by Sonchus spp. (S. oleraceus L., S. asper L. and S. arvensis L.) (0.76). The plant parts preferably used are leaves (22 plants), fruits (12) and stems (7). Only six wild plants were indicated as having both food use and therapeutic effect. The survey conducted on the traditional use of wild food plants in the Middle Agri Valley revealed that this cultural heritage is only partially retained by the population. Over the last few decades, this knowledge has been in fact quickly disappearing along with the people and, even in the rural context of the study area, is less and less handed down to younger generations. Nevertheless, data also revealed that the use of wild plants is recently being revaluated in a way closely related to local habits and traditions.

  9. Geomorphologic study and numerical modeling of the T. Regoud debris flows, in Rhemes Valley, Aosta (NW Italy (United States)

    Mandrone, Giuseppe; Filipello, Andrea


    The T. Regoud is a small stream in a secondary valley of Aosta Valley, NW Italy. Its bedrock is formed by polimethamorphic rock masses with thin covers of slope deposits. The morphometric analysis and geomorphological survey have allowed the identification, based on existing maps and through the use of GIS applications, of the main elements of the river basin. In particular, between 2260 and 2880 m a.s.l.m. there is a large debris accumulation. This accumulation is fed by two rock falls: the first acts directly on the rocky wall, the second, coinciding with the watershed between the Regoud and the Bioula (a stream immediately to the right), which insists on ablation of glacial deposits. The T. Regoud study foucoused also reconstruction of past events and corresponding analysis of their distribution in time, identifying the highest risk period between June and September in conjunction with short but intense rainfall, typical summerlike in the Alps. The research of mobilized material volumes was carried out by comparing orthophotos from 2006 and 2012. Through the superposition of these images, it has identified the areal extent of the reservoir of the debris. The code used for the simulation of the flows is called r.massmov and is capable of simulating the propagation of a debris flow on topographies particularly complex. The model is the result of the implementation MassMov2D as a plugin of GRASS GIS. The plugin requires as input the volume of material taken over from the event. The volume obtained from aerial photo comparison (about 19000 m3) was considered as the solid volume but adding the liquid volume (estimated in the 30% of the solid volume) we reached a volume of 25.000 cubic meters. The software have allowed the construction of a realistic model of detachment, very usefull for future simulations..

  10. Early breakdown of isolation revealed by marriage behaviour in a Ladin-speaking community (Gardena Valley, South Tyrol, Italy, 1825-1924). (United States)

    Gueresi, Paola


    The aim of this study was to investigate marriage behaviour from 1825 to 1924 in an Alpine valley inhabited by Ladin speakers (Gardena Valley, South Tyrol, Italy), where the particular geographic, linguistic and economic characteristics may have influenced the level of reproductive isolation. A total of 2183 marriage acts from the two main parishes of Santa Cristina and Ortisei were examined. Birth and residence endogamy, inbreeding coefficients from dispensations and from isonymy, birth place distribution of the spouses and isonymic relationships were analysed in four 25-year sub-periods. All the indicators considered point to a lower level of reproductive isolation at Ortisei, a main centre for the woodcarving industry, which appeared to be experiencing an early and effective breakdown of isolation. Marriage behaviour in the Gardena Valley between 1825 and 1924 seems to have been mostly influenced by socioeconomic factors rather than linguistic and cultural ones.

  11. Analysis of shallow failures triggered by the 14-16 November 2002 event in the Albaredo valley, Valtellina (Northern Italy

    Directory of Open Access Journals (Sweden)

    S. Dapporto


    Full Text Available On 14-16 November 2002 the North Italy was affected by an intense rainfall event: in the Albaredo valley (Valtellina more than 200 mm of rain fell triggering about 50 shallow landslides, mainly soil slips and soil slip-debris flows. Landslides occurred above the critical rainfall thresholds computed by Cancelli and Nova (1985 and Ceriani et al. (1994 for the Italian Central Alps: in fact the cumulative precipitation at the soil slips initiation time was 230 mm (in two days with a peak intensity of 15 mm/h. A coupled analysis of seepage and instability mechanisms is performed in order to evaluate the potential for slope failure during the event. Changes in positive and negative pore water pressures during the event are modelled by a finite element analysis of water flow in transient conditions, using as boundary condition for the nodes along the slope surface the recorded rainfall rate. The slope stability analysis is conducted applying the limit equilibrium method, using pore water pressure distributions obtained in the different time steps by the seepage analysis as input data for the calculation of the factor of safety.

  12. Landscape analysis for multi-hazard prevention in Orco and Soana valleys, Northwest Italy (United States)

    Turconi, L.; Tropeano, D.; Savio, G.; De, S. K.; Mason, P. J.


    The study area (600 km2), consisting of Orco and Soana valleys in the Western Italian Alps, experienced different types of natural hazards, typical of the whole Alpine environment. Some of the authors have been requested to draw a civil protection plan for such mountainous regions. This offered the special opportunity (1) to draw a lot of unpublished historical data, dating back several centuries mostly concerning natural hazard processes and related damages, (2) to develop original detailed geo-morphological studies in a region still poorly known, (3) to prepare detailed thematic maps illustrating landscape components related to natural conditions and hazards, (4) to thoroughly check present-day situations in the area compared to the effects of past events and (5) to find adequate natural hazard scenarios for all sites exposed to risk. The method of work has been essentially to compare archival findings with field evidence in order to assess natural hazard processes, their occurrence and magnitude, and to arrange all such elements in a database for GIS-supported thematic maps. Several types of natural hazards, such as landslides, rockfalls, debris flows, stream floods and snow avalanches cause huge damage to lives and properties (housings, roads, tourist sites). We aim to obtain newly acquired knowledge in this large, still poorly understood area as well as develop easy-to-interpret products such as natural risk maps.

  13. Impact of wild ungulates on coppices from the Bisenzio Valley (province of Prato, Italy

    Directory of Open Access Journals (Sweden)

    Bianchi L


    Full Text Available Similar to other Apennine areas, a considerable increase of wild ungulate density has been observed in the past decades in the Bisenzio valley (province of Prato, leading to a strong impact on coppice regeneration. In some felling areas, the prolonged browsing on young suckers turned the stumps into low and dense bushes, thus threatening the survival of the forest stand and triggering a loss of environmental stability. The aim of this work was to study the impact of deer on sprout regeneration after cutting in mixed coppices felled in the period 2007-2010 and characterized by the dominance of chestnut, hornbeam, Turkey oak, and beech. Some 36 plots were established in four municipal districts of the Prato province (Cantagallo, Vernio, Montemurlo, Vaiano. Damage and browsing intensity on each stump were evaluated using an index that allowed the comparison among different areas and fores stand types. Regardless of the species, over 90% of the sprouts revealed a very strong damage, whereas only 6% did not exhibit any damage. A significant difference in the sprout height was detected between browsed and non-browsed areas. Despite a high incidence of damage in all the studied areas, chestnut showed a greater resilience against browsing. In summary, overgrazing by wild game may determine severe contraints to the evolutionary dynamics of forest stands, frustrating the effects of silvicultural practices. The possible benefits of the implementation of a large-scale integrated wildlife plan, including hunting and forest-evironmental management are discussed.

  14. What Factors Encourage Intrafamily Farm Succession in Mountain Areas? Evidence From an Alpine Valley in Italy

    Daniele Cavicchioli


    Full Text Available Family farming plays a vital role in mountain areas. Its survival is related to multiple factors, including intrafamily farm succession. This study examined data on apple-producing family farms in an Italian Alpine valley, trying to identify which factors foster or discourage intrafamily succession and to what extent they do this, both at the farm level and from the potential successor's viewpoint. To do so, various farm, farmer, and individual characteristics were analyzed using probabilistic regression. We found that intrafamily succession was more likely when the farm was managed by a woman (+20% with a high school diploma (+13% who had at least 1 child with specialized education in agriculture (+27% and when farm sales had increased in recent years (+25%. We also found that a child's willingness to take over the family farm decreases as the number of farm children increases and when the child is a female with a high school diploma; however, the likelihood that children will take over the family business rises as farmer education level and work experience increase. These findings, while mixed, suggest that women play a key role in keeping family farming alive in mountain areas, along with education of family members, improved marketability of agricultural products, and in general, competitiveness and profitability of the family farm.

  15. Statistical analysis and modelling of weather radar beam propagation conditions in the Po Valley (Italy

    Directory of Open Access Journals (Sweden)

    A. Fornasiero


    Full Text Available Ground clutter caused by anomalous propagation (anaprop can affect seriously radar rain rate estimates, particularly in fully automatic radar processing systems, and, if not filtered, can produce frequent false alarms. A statistical study of anomalous propagation detected from two operational C-band radars in the northern Italian region of Emilia Romagna is discussed, paying particular attention to its diurnal and seasonal variability. The analysis shows a high incidence of anaprop in summer, mainly in the morning and evening, due to the humid and hot summer climate of the Po Valley, particularly in the coastal zone. Thereafter, a comparison between different techniques and datasets to retrieve the vertical profile of the refractive index gradient in the boundary layer is also presented. In particular, their capability to detect anomalous propagation conditions is compared. Furthermore, beam path trajectories are simulated using a multilayer ray-tracing model and the influence of the propagation conditions on the beam trajectory and shape is examined. High resolution radiosounding data are identified as the best available dataset to reproduce accurately the local propagation conditions, while lower resolution standard TEMP data suffers from interpolation degradation and Numerical Weather Prediction model data (Lokal Model are able to retrieve a tendency to superrefraction but not to detect ducting conditions. Observing the ray tracing of the centre, lower and upper limits of the radar antenna 3-dB half-power main beam lobe it is concluded that ducting layers produce a change in the measured volume and in the power distribution that can lead to an additional error in the reflectivity estimate and, subsequently, in the estimated rainfall rate.

  16. Environmental quality of a semi-natural area of the Po Valley (northern Italy): aspects of soil and vegetation. (United States)

    Manfredi, Paolo; Giupponi, Luca; Cassinari, Chiara; Trevisan, Marco


    This work, originating in the preliminary analyses of a Life project and co-financed by the European Union ("Environmental recovery of degraded soils and desertified by a new treatment technology for land reconstruction", Life 10 ENV IT 400 "New Life";, aims to evaluate the environmental quality of a semi-natural area of the Po Valley (northern Italy) by analysing the characteristics of soil and vegetation. The area of study is located in the municipal territory of Piacenza (Emilia-Romagna, Italy) along the eastern shores of the river Trebbia and is made up of the closed landfill of Solid Urban Waste of Borgotrebbia (active from 1972 to 1985) and of the neighbouring areas (in North-South order: riverside area, northern borders of the landfill, landfill disposal, southern borders and cultivated corn fields). For each area pedological and vegetational analyses were carried out and in particular, as regards the soil, various chemical-physical analyses were done among which: pH, organic carbon, total nitrogen, salinity, exchangeable bases and granulometry. The ground vegetation data were collected using phytosociological relevés according to the method of the Zurich-Montpellier Sigmatist School, (Braun-Blanquet, 1964). For the analysis of the environmental quality of each area, the floristic-vegetation indexes system was applied as proposed by Taffetani & Rismondo (2009) (updated by Rismondo et al., 2011) conveniently created for analysing the ecological functionality of the agro-ecosystems. The results obtained by such applications drew attention to a dynamic vegetation mass in the landfill which, despite a value of the floristic biodiversity index (IFB) comparable to that of the borders, shows a much lower value of the maturity index (IM). This is due to the elevated percentage of annual species (index of the therophytic component = 52.78%) belonging to the phytosociological class Stellarietea mediae Tüxen, Lohmeyer & Preising ex

  17. Groundwater vulnerability to climate variability: modelling experience and field observations in the lower Magra Valley (Liguria, Italy) (United States)

    Menichini, Matia; Doveri, Marco; El Mansoury, Bouabid; El Mezouary, Lhoussaine; Lelli, Matteo; Raco, Brunella; Scozzari, Andrea; Soldovieri, Francesco


    The aquifer of the Lower Magra Valley (SE Liguria, Italy) extends in a flat plain, where two main rivers (Magra and Vara) flow. These rivers are characterized by a wide variation of water level and water chemical composition (TDS, Cl and SO4) due to the combination of rainfall regime and the presence of thermal springs in the inner part of the catchment area. Groundwater flow is apparently controlled by stream water infiltration, which affects both water levels and water quality. In particular, the wide range of variation of some particular chemical species in the stream water influences the groundwater chemistry on a seasonal basis. In the area of interest, there is an important well-field, which supplies most of the drinking water to the nearby city of La Spezia. In this context, the groundwater system is exposed to a high degree of vulnerability, both in terms of quality and quantity. This study is aimed to develop a predictive flow and transport model in order to assess the vulnerability s.l. of the Magra Valley aquifer system and to evaluate its behaviour in awaited climate scenarios. A flow and transport model was developed by using MODFLOW and MT3DMS codes, and it's been calibrated in both steady state and transient conditions. The model confirmed the importance of the Magra river in the water balance and chemical composition of the extracted groundwater. In addition, a data-driven modelling approach was applied in order to determine boundary conditions (e.g. rivers and constant head or general head boundaries) of the physical model under hypothetic future climate scenarios. For this purpose, fully synthetic datasets have been generated as a training set of the data-driven scheme, with input variables inspired by selected climate models and input/output relationships estimated by past observations. An experimental run of the flow-transport model for 30 years ahead was performed, based on such hypothetic scenarios. This approach highlighted how the

  18. A new subdivision of the central Sesia Zone (Aosta Valley, Italy) (United States)

    Giuntoli, Francesco; Engi, Martin; Manzotti, Paola; Ballèvre, Michel


    The Sesia Zone in the Western Alps is a continental terrane probably derived from the NW-Adriatic margin and polydeformed at HP conditions during Alpine convergence. Subdivisions of the Sesia Zone classically have been based on the dominant lithotypes: Eclogitic Micaschist Complex, Seconda Zona Diorito-Kinzigitica, and Gneiss Minuti Complex. However, recent work (Regis et al., 2014) on what was considered a single internal unit has revealed that it comprises two or more tectonic slices that experienced substantially different PTDt-evolutions. Therefore, detailed regional petrographic and structural mapping (1:3k to 1:10k) was undertaken and combined with extensive sampling for petrochronological analysis. Results allow us to propose a first tectonic scheme for the Sesia Zone between the Aosta Valley and Val d'Ayas. A set of field criteria was developed and applied, aiming to recognize and delimit the first order tectonic units in this complex structural and metamorphic context. The approach rests on three criteria used in the field: (1) Discontinuously visible metasedimentary trails (mostly carbonates) considered to be monocyclic (Permo-Mesozoic protoliths); (2) mappable high-strain zones; and (3) visible differences in the metamorphic imprint. None of these key features used are sufficient by themselves, but in combination they allow us to propose a new map that delimits main units. We propose an Internal Complex with three eclogitic sheets, each 0.5-3 km thick. Dominant lithotypes include micaschists associated with mafic rocks and minor orthogneiss. The main foliation is of HP, dipping moderately NW. Each of these sheets is bounded by (most likely monometamorphic) sediments, glaucophane, and garnet occur as relics. Towards the SW, the width of the Intermediate Complex is reduced from 0.5 km to a few meters. In the External Complex several discontinuous lenses occur; these comprise 2DK-lithotypes and are aligned with greenschist facies shear zones mapped within

  19. Geochemical study of travertines along middle-lower Tiber valley (central Italy): genesis, palaeo-environmental and tectonic implications (United States)

    Giustini, Francesca; Brilli, Mauro; Mancini, Marco


    Several travertine deposits dating to the Pleistocene outcrop along the Tiber valley between Orte and Rome. Mineralogically, they are mainly composed of calcite; various lithofacies (stromatolitic, phytoclastic, and massive) were identified and relatively wide ranges of carbon (δ13C -8.11 to +11.42‰ vs. VPDB) and oxygen (δ18O +22.74 to +27.71‰ vs. VSMOW) isotope compositions were measured. The isotope and chemical compositions of water and free gases, in some cases associated with the travertines, were also measured. Carbon isotope data show that several samples fall in the typical range of thermogenic travertine, i.e., linked to the addition of deep inorganic CO2. The oxygen isotope composition of the springs associated with the travertine deposits points to travertine precipitation by slightly thermal water of meteoric origin. In general, these travertines are in association with, or close to, mineralised groundwaters (with slightly acidic pH, low thermalism, and enrichment in sulphates or sodium chloride) and rich CO2 gas emissions, the origin of which may be linked to decarbonation reactions. The travertine bodies are locally connected with crustal structural lineaments favouring the circulation of ascending deep CO2-rich fluids. Conversely, some samples show isotopic connotations of meteogenic deposits, representing travertines formed mainly from soil biogenic or atmospheric carbon dioxide generally present in shallow groundwater or surface water. According to their morphology and isotope data, these travertines may be attributed to the sedimentary environment of waterfalls. These new geochemical and morphological data are integrated with those already available in the literature regarding the study area and contribute to shedding light on palaeo-environmental conditions in western-central Italy during the Quaternary.

    Directory of Open Access Journals (Sweden)

    P. Wang


    Full Text Available During the second FORMAT (FORMaldehyde as A Tracer of oxidation in the troposphere campaign in 2003 the airborne multi-axis DOAS instrument (AMAXDOAS performed scattered-light spectroscopic measurements of SO2 over the city of Mantova and the power plant Porto Tolle, both situated in the Po-valley, Northern Italy. The SO2 vertical columns and emission flux were derived from two days of measurements, 26 and 27 September 2003. The SO2 emission flux from the power plant Porto Tolle was calculated to 1.93×1025 molec s-1 on 26 September and in good agreement with official emission data, which quote 2.25×1025 molec s-1. On 27 September the measured flux was much lower (3.77×1024 molec s-1 if ECMWF wind data are used, but of comparable magnitude (2.4×1025 molec s-1 if the aircraft on-board wind measurements are utilised. Official emission data was 2.07×1025 molec s-1 indicating only a small change from the previous day. Over the city of Mantova, the observed SO2 vertical columns were 1.1×1016 molec cm-2 and 1.9×1016 molec cm-2 on 26 and 27 September, respectively. This is in good agreement with ground-based measurements of 5.9 ppbv and 10.0 ppbv which correspond to 1.2×1016 molec cm-2 and 2.2×1016 molec cm-2 if a well mixed boundary layer of 500m altitude is assumed.

  1. A combined road weather forecast system to prevent road ice formation in the Adige Valley (Italy) (United States)

    Di Napoli, Claudia; Piazza, Andrea; Antonacci, Gianluca; Todeschini, Ilaria; Apolloni, Roberto; Pretto, Ilaria


    Road ice is a dangerous meteorological hazard to a nation's transportation system and economy. By reducing the pavement friction with vehicle tyres, ice formation on pavements increases accident risk and delays travelling times thus posing a serious threat to road users' safety and the running of economic activities. Keeping roads clear and open is therefore essential, especially in mountainous areas where ice is likely to form during the winter period. Winter road maintenance helps to restore road efficiency and security, and its benefits are up to 8 times the costs sustained for anti-icing strategies [1]. However, the optimization of maintenance costs and the reduction of the environmental damage from over-salting demand further improvements. These can be achieved by reliable road weather forecasts, and in particular by the prediction of road surface temperatures (RSTs). RST is one of the most important parameters in determining road surface conditions. It is well known from literature that ice forms on pavements in high-humidity conditions when RSTs are below 0°C. We have therefore implemented an automatic forecast system to predict critical RSTs on a test route along the Adige Valley complex terrain, in the Italian Alps. The system considers two physical models, each computing heat and energy fluxes between the road and the atmosphere. One is Reuter's radiative cooling model, which predicts RSTs at sunrise as a function of surface temperatures at sunset and the time passed since then [2]. One is METRo (Model of the Environment and Temperature of Roads), a road weather forecast software which also considers heat conduction through road material [3]. We have applied the forecast system to a network of road weather stations (road weather information system, RWIS) installed on the test route [4]. Road and atmospheric observations from RWIS have been used as initial conditions for both METRo and Reuter's model. In METRo observations have also been coupled to

  3. Fracture characterization of flysch formation by terrestrial digital photogrammetry: an example in the Antola Formation (upper Staffora Valley, Italy) (United States)

    Meisina, Claudia; Menegoni, Niccolò; Perotti, Cesare


    Geomechanical characterization of flysch formations plays an important role for its implication in slope stability and fluids circulation, especially in Apenninic areas. The Antola Formation of Upper Cretaceous age crops out extensively in the Northern Apennines and provides an important case of study. It consists of turbiditic graded units of calcareous sandstones, sandstones, marlstones, and shales and is interpreted as a deep-sea basin plain deposit, with lateral facies variations which range from proximal, thick-bedded turbidities to distal turbidites that show predominantly thickening upward cycles and have a high percentage of shale. It is in general characterized by folds developed in absence of metamorphism and a usually high degree of fracturation. The presence of well developed fracture networks enhances circulation of fluid and therefore alteration of the less competent layers causing problems of slope stability. Fracture characterization of Antola Formation based on field survey is very time consuming and often limited by the insufficient availability and inaccessibility of outcrops. For this reason, terrestrial remote sensing and in particular terrestrial digital photogrammetry has been applied to investigate the geomechanical features of the formation in the upper Staffora Valley (Northern Italy). Digital photogrammetry allows to generate by Structure from Motion (SfM) technique a 3D point cloud that represents the Digital Outcrop Model (DOM). New technologies allow to associate appropriate texture to the point cloud from the images, in order to preserve important visual information. The analysis of several textured 3D DOMs allows to digitally acquire a large amount of data on discontinuities parameters such as orientation, spacing, aperture, persistence and filling, in order to better characterize the rock mass. Some tests performed by field survey data acquisition to validate the digitally collected data, gave positive results, showing differences

    Full Text Available This work is part of a research on the use of terrestrial laser scanner, integrated with total station and GPS, for the documentation and comprehension of complex architectures in up-land sites. The research is performed in the framework of the project "Ambiente e Paesaggi dei siti di Altura Trentini" – APSAT (Environment and landscape of hill-top sites in Trentino, a multidisciplinary project focused on the evolution of hill-top anthropic system in the Trentino region, Italy. The study area is located in the Gresta Valley and this work concerns on the Nagià Grom site, fortified by the Austria-Hungarian Army during the World War I. The site has been interested by a significant restore operation of a large series of entrenches paths and fortifications in the last decade. The survey herein described has involved an area once interested by military barracks with Officers' Mess, water provision and by one of the biggest field kitchens discovered in the Trentino region. A second survey involved the tunnel connecting the ammunition depot to the artillery stations. The nature of such complex architectures, characterized by an irregular and composite 3D span leads, in general, to necessary simple surveys and representations and somehow to simplified studies too. The 3D point cloud, once filtered by the massive presence of dense vegetation, eventually constitutes a rich data set for further analyses on the spatial, geological, architectural and historical properties of the site. The analysis has been carried out on two different scales. At the architectural-scale, the comparison to historic photos has allowed to understand how the original structure of the barracks was made and to find building characters that now are lost. The on-site observation of the underground stratigraphic splices and their analysis in the 3D point cloud, e.g., spatial extension and slope, have permitted the understanding of the special excavation process guided by the

  5. PEBBED Uncertainty and Sensitivity Analysis of the CRP-5 PBMR DLOFC Transient Benchmark with the SUSA Code

    Energy Technology Data Exchange (ETDEWEB)

    Gerhard Strydom


    The need for a defendable and systematic uncertainty and sensitivity approach that conforms to the Code Scaling, Applicability, and Uncertainty (CSAU) process, and that could be used for a wide variety of software codes, was defined in 2008. The GRS (Gesellschaft für Anlagen und Reaktorsicherheit) company of Germany has developed one type of CSAU approach that is particularly well suited for legacy coupled core analysis codes, and a trial version of their commercial software product SUSA (Software for Uncertainty and Sensitivity Analyses) was acquired on May 12, 2010. This report summarized the results of the initial investigations performed with SUSA, utilizing a typical High Temperature Reactor benchmark (the IAEA CRP-5 PBMR 400MW Exercise 2) and the PEBBED-THERMIX suite of codes. The following steps were performed as part of the uncertainty and sensitivity analysis: 1. Eight PEBBED-THERMIX model input parameters were selected for inclusion in the uncertainty study: the total reactor power, inlet gas temperature, decay heat, and the specific heat capability and thermal conductivity of the fuel, pebble bed and reflector graphite. 2. The input parameters variations and probability density functions were specified, and a total of 800 PEBBED-THERMIX model calculations were performed, divided into 4 sets of 100 and 2 sets of 200 Steady State and Depressurized Loss of Forced Cooling (DLOFC) transient calculations each. 3. The steady state and DLOFC maximum fuel temperature, as well as the daily pebble fuel load rate data, were supplied to SUSA as model output parameters of interest. The 6 data sets were statistically analyzed to determine the 5% and 95% percentile values for each of the 3 output parameters with a 95% confidence level, and typical statistical indictors were also generated (e.g. Kendall, Pearson and Spearman coefficients). 4. A SUSA sensitivity study was performed to obtain correlation data between the input and output parameters, and to identify the

  7. Uncertainty and Sensitivity Studies with TRACE-SUSA and TRACE-DAKOTA by Means of Steady State BFBT Data

    Directory of Open Access Journals (Sweden)

    Wadim Jaeger


    Full Text Available The subject of the present paper is the uncertainty and sensitivity studies for steady state BFBT results including pressure drop and void fraction measurements. The investigations are performed with TRACE (version 5.0 patch 2, thermal hydraulic modeling, and SUSA and DAKOTA; both tools are for the evaluation of uncertainties and sensitivities. For this purpose, the NUPEC BFBT experimental data base is used. The advantage of applying two different uncertainty and sensitivity tools in combination with TRACE is that the user effect can be excluded. Since in both cases the TRACE model of the BFBT bundle is identical the differences in the results are related to the capabilities of the uncertainty and sensitivity tools. The reference results with TRACE show that the code is very well able to represent both single- and two-phase flows even though it is a 1D coarse mesh system code. For selected cases, an uncertainty study was performed. Even though a reduced number of uncertain parameters are considered in the DAKOTA investigation, compared to the one with SUSA, similar results are obtained. The results indicate also that even small parameter variations can yield to rather large variations of the selected output parameters.

  8. A geographical information system-based multicriteria evaluation to map areas at risk for Rift Valley fever vector-borne transmission in Italy. (United States)

    Tran, A; Ippoliti, C; Balenghien, T; Conte, A; Gely, M; Calistri, P; Goffredo, M; Baldet, T; Chevalier, V


    Rift Valley fever (RVF) is a severe mosquito-borne disease that is caused by a Phlebovirus (Bunyaviridae) and affects domestic ruminants and humans. Recently, its distribution widened, threatening Europe. The probability of the introduction and large-scale spread of Rift Valley fever virus (RVFV) in Europe is low, but localized RVF outbreaks may occur in areas where populations of ruminants and potential vectors are present. In this study, we assumed the introduction of the virus into Italy and focused on the risk of vector-borne transmission of RVFV to three main European potential hosts (cattle, sheep and goats). Five main potential mosquito vectors belonging to the Culex and Aedes genera that are present in Italy were identified in a literature review. We first modelled the geographical distribution of these five species based on expert knowledge and using land cover as a proxy of mosquito presence. The mosquito distribution maps were compared with field mosquito collections from Italy to validate the model. Next, the risk of RVFV transmission was modelled using a multicriteria evaluation (MCE) approach, integrating expert knowledge and the results of a literature review on host sensitivity and vector competence, feeding behaviour and abundance. A sensitivity analysis was performed to assess the robustness of the results with respect to expert choices. The resulting maps include (i) five maps of the vector distribution, (ii) a map of suitable areas for vector-borne transmission of RVFV and (iii) a map of the risk of RVFV vector-borne transmission to sensitive hosts given a viral introduction. Good agreement was found between the modelled presence probability and the observed presence or absence of each vector species. The resulting RVF risk map highlighted strong spatial heterogeneity and could be used to target surveillance. In conclusion, the geographical information system (GIS)-based MCE served as a valuable framework and a flexible tool for mapping the

  9. The interaction between surface processes and tectonics during the late Quaternary in the Middle Volturno River valley (southern Italy): new morpho-stratigraphic constraints from fluvial terraces (United States)

    Amato, Vincenzo; Patrizio Ciro Aucelli, Pietro; Cesarano, Massimo; Filocamo, Francesca; Giralt, Santiago; Leone, Natalia; Rosskopf, Carmen Maria; Scorpio, Vittoria


    The Middle Volturno River valley is located in the inner part of the Southern Apennines of Italy, between the SW slope of the Matese Massif and the NE slopes of the Caserta mountains and is underlain by Meso-Cenozoic carbonate rocks and Miocene Flysch deposits. The study sector includes the lower Calore River valley and, below the Calore-Volturno confluence, the valley portion that extends until the Triflisco gorge, from Telese village to the Volturno dam. It is generally E-W, NW-SE and NE-SW elongated and characterized by rectilinear and meandering fluvial patterns. The main infilling of the two valley portions is locally preserved as remnants of fluvial terraces hanging over the local base level up to ca. 30-40 m. It is generally interfingered with and covered by several generations of alluvial fan and travertine deposits. New Ar/Ar datings on tephra layers interbedded in the oldest generations of the alluvial fan deposits and new U/Th datings on travertine deposits, allowed to constrain the main infilling to the late Middle and the early Upper Pleistocene. Both deposits are locally covered by the Campanian Ignimbrite Formation (CI, 39 ky BP) and are interested by high-angle faults generated during extensional tectonic phases that affected this sector of the Apennine chain since the Middle Pleistocene. Furthermore, the geomorphological analyses of aerial photos and topographic maps (1:5000 in scale) highlight the presence of a flight of fluvial terraces younger than the CI deposits that can be grouped into four orders. The stratigraphical data, based on field surveys and boreholes analyses, supported by new tephrostratigraphical constraints and literature data, allow to refer the older orders (I and II) to the late Upper Pleistocene. The III and IV orders, instead, can be referred to the early Holocene and historical times, respectively. These chronological constraints allow to hypothesize that the genesis of the I and II orders seem to be driven by late

    Full Text Available GPS, digital photogrammetry and laser scanning techniques have been applied and compared in the frame of the studies of two complex landslides located in the Emilia-Romagna Region (Northern Italy. The three approaches, characterized by different accuracies, applicability and costs, have demonstrated to be efficient tools to define Digital Elevation Models computed in the same reference system and able to provide data on the landslide motion. The results described in the paper indicate the present low level of landslide activity in recent years. Reliability, costs and execution times of the applied surveying methods are shown and discussed in this paper.

  12. Modeling groundwater/surface-water interactions in an Alpine valley (the Aosta Plain, NW Italy): the effect of groundwater abstraction on surface-water resources (United States)

    Stefania, Gennaro A.; Rotiroti, Marco; Fumagalli, Letizia; Simonetto, Fulvio; Capodaglio, Pietro; Zanotti, Chiara; Bonomi, Tullia


    A groundwater flow model of the Alpine valley aquifer in the Aosta Plain (NW Italy) showed that well pumping can induce river streamflow depletions as a function of well location. Analysis of the water budget showed that ˜80% of the water pumped during 2 years by a selected well in the downstream area comes from the baseflow of the main river discharge. Alluvial aquifers hosted in Alpine valleys fall within a particular hydrogeological context where groundwater/surface-water relationships change from upstream to downstream as well as seasonally. A transient groundwater model using MODFLOW2005 and the Streamflow-Routing (SFR2) Package is here presented, aimed at investigating water exchanges between the main regional river (Dora Baltea River, a left-hand tributary of the Po River), its tributaries and the underlying shallow aquifer, which is affected by seasonal oscillations. The three-dimensional distribution of the hydraulic conductivity of the aquifer was obtained by means of a specific coding system within the database TANGRAM. Both head and flux targets were used to perform the model calibration using PEST. Results showed that the fluctuations of the water table play an important role in groundwater/surface-water interconnections. In upstream areas, groundwater is recharged by water leaking through the riverbed and the well abstraction component of the water budget changes as a function of the hydraulic conditions of the aquifer. In downstream areas, groundwater is drained by the river and most of the water pumped by wells comes from the base flow component of the river discharge.

The railway station’s transparent volume - a 385 m (the length of the TGV long steel and glass tunnel, 30 m. width, with a variable height compared to the outdoor street level (between 12 and 3 m at the height of the cover - is proposed as a modern reinterpretation of the nineteenth century’s urban galleries and the great historical station’s halles, as well as a kind of symbolic building.

    Crupi, Vincenza; D'Amico, Sebastiano; Majolino, Domenico; Paladini, Giuseppe; Persico, Raffaele; Saccone, Mauro; Spagnolo, Grazia; Venuti, Valentina


    In the framework of the National School "Science and Cultural Heritage: from Non-Invasive Analysis to 3D Recostruction" (19-23 September 2016, Messina-Valle d'Agrò, Italy), organized by the Department of Mathematical and Computer Sciences, Physical Sciences and Earth Sciences of the University of Messina, in co-opeartion with the Department of Geosciences of the University of Malta and in agreement with the Regional Order of Geologists of Sicily, non-invasive investigations have been performed aimed at the exploitation, fruition and safeguard of the archaeological site of Scifì and the St Peter and Paul Church in Agro Valley. Different georadar prospections [1-2] were carried out at both sites. Prospections have been performed by using a Ris-Hi mode system equipped with a dual antenna at the central frequencies of 200 and 600 MHz [3], and made along an orthogonal grid with 40 cm spacing. Data processing involved a zero timing, background removal on all tracks, a gain in-depth, a one-dimensional Butterworth filtering and a Kirchoff migration. Measurements of ambient vibrations were also performed [4-5], that revealed the absence of remarkable side heterogeneities, or large impedance contrasts associated surface stratigraphy. Measurements were also taken to measure the natural frequency of the church. In the two investigated sites, we also conducted spectroscopic investigations. The analysis was mainly focused on the study of variations, in terms of elemental composition by means of X-ray fluorescence (XRF) measurements as well as Raman spectrospopy which allow to determine the elemental composition of the sample under investigation. In addition, several images (by means of drones) were also collected in order to create a detailed 3D model for each site the ultimate goal of creating a digital archive for the virtual use of sites of interest.

  15. Landslide susceptibility assessment in the Upper Orcia Valley (Southern Tuscany, Italy through conditional analysis: a contribution to the unbiased selection of causal factors

    Directory of Open Access Journals (Sweden)

    F. Vergari


    Full Text Available In this work the conditional multivariate analysis was applied to evaluate landslide susceptibility in the Upper Orcia River Basin (Tuscany, Italy, where widespread denudation processes and agricultural practices have a mutual impact. We introduced an unbiased procedure for causal factor selection based on some intuitive statistical indices. This procedure is aimed at detecting among different potential factors the most discriminant ones in a given study area. Moreover, this step avoids generating too small and statistically insignificant spatial units by intersecting the factor maps. Finally, a validation procedure was applied based on the partition of the landslide inventory from multi-temporal aerial photo interpretation.

    Although encompassing some sources of uncertainties, the applied susceptibility assessment method provided a satisfactory and unbiased prediction for the Upper Orcia Valley. The results confirmed the efficiency of the selection procedure, as an unbiased step of the landslide susceptibility evaluation. Furthermore, we achieved the purpose of presenting a conceptually simple but, at the same time, effective statistical procedure for susceptibility analysis to be used as well by decision makers in land management.

  16. Uncertainty Estimation and Evaluation of Shallow Aquifers’ Exploitability: The Case Study of the Adige Valley Aquifer (Italy

    Directory of Open Access Journals (Sweden)

    Marta Castagna


    Full Text Available Evaluating the sustainability of water uses in shallow aquifers is fundamental for both environmental and socio-economic reasons. Groundwater models are the main tools to sustain informed management plans, yet simulation results are affected by both epistemic and parametric uncertainties. In this study, we aim at investigating the effect of model uncertainties on three assessment criteria: depth to water (DTW, recharge/discharge analysis and a newly defined sustainability index S. We consider, as a case study, the shallow aquifer of the Adige Valley, which is highly influenced by surface water dynamics, water withdrawals from pumping wells and a dense network of ditches. Both direct measurements and soft data are used to reduce uncertainty associated to the limited knowledge about the spatial distribution of the hydraulic parameters. Simulation results showed that the aquifer is chiefly influenced by the interaction with the Adige River and that the influence of anthropogenic activities on vulnerability of groundwater resources varies within the study area. This calls for differentiated approaches to water resources management. Uncertainty related to the three assessment criteria is chiefly controlled by uncertainty of the hydrogeological model, although it depends also on the strategy adopted for the management of water resources.

  17. A new magnetotelluric monitoring network operating in Agri Valley (Southern Italy: study of stability of apparent resistivity estimates

    Directory of Open Access Journals (Sweden)

    L. Telesca


    Full Text Available Variations detected in geophysical, especially electromagnetic, parameters in seismic active areas have been sometimes attributed to modifications of the stress field. Among the different geophysical methods, magnetotellurics (MT could be one of the most effective because it allows us to explore down to seismogenic depths. Continuous MT recording could allow us to evaluate whether possible variations are significantly correlated with the seismic activity of investigated area. To assess the significance of such observations we must be able to say how well an apparent resistivity curve should be reproduced when measurements are repeated at a later time. To do this properly it is essential to know that the estimated error bars accurately represent the true uncertainties in comparing the transfer functions. In this work we will show the preliminary results obtained from the analysis of the data coming from the new MT monitoring network installed in Agri Valley. This analysis gives us the possibility: i to better study the temporal stability of the signals, ii to better discriminate the noise affecting the measures by remote reference estimation. The performed analysis disclosed a relatively low degree of noise in the investigated area, which is a promising condition for monitoring.

  18. Variations in the chemical composition of the submicron aerosol and in the sources of the organic fraction at a regional background site of the Po Valley (Italy) (United States)

    Fine particulate matter (PM) levels and resulting impacts on human health are in the Po Valley (Italy) among the highest in Europe. To build effective PM abatement strategies, it is necessary to characterize fine PM chemical composition, sources and atmospheric processes on long timescales (> months), with short time resolution (organic fraction. Although previous studies have been conducted in this region, none of them addressed all these aspects together. For the first time in the Po Valley, we investigate the chemical composition of nonrefractory submicron PM (NR-PM1) with a time resolution of 30 min at the regional background site of Ispra during 1 full year, using the Aerodyne Aerosol Chemical Speciation Monitor (ACSM) under the most up-to-date and stringent quality assurance protocol. The identification of the main components of the organic fraction is made using the Multilinear-Engine 2 algorithm implemented within the latest version of the SoFi toolkit. In addition, with the aim of a potential implementation of ACSM measurements in European air quality networks as a replacement of traditional filter-based techniques, parallel multiple offline analyses were carried out to assess the performance of the ACSM in the determination of PM chemical species regulated by air quality directives. The annual NR-PM1 level monitored at the study site (14.2 µg m-3) is among the highest in Europe and is even comparable to levels reported in urban areas like New York City and Tokyo. On the annual basis, submicron particles are primarily composed of organic aerosol (OA, 58 % of NR-PM1). This fraction was apportioned into oxygenated OA (OOA, 66 %), hydrocarbon-like OA (HOA, 11 % of OA) and biomass burning OA (BBOA, 23 %). Among the primary sources of OA, biomass burning (23 %) is thus bigger than fossil fuel combustion (11 %). Significant contributions of aged secondary organic aerosol (OOA) are observed throughout the year. The unexpectedly high degree of oxygenation

    Three 2-D Deep Electrical Resistivity Tomography (ERT) transects, up to 6.36 km long, were obtained across the Paganica-San Demetrio Basin, bounded by the 2009 L'Aquila Mw 6.1 normal-faulting earthquake causative fault (central Italy). The investigations allowed defining for the first time the shallow subsurface basin structure. The resistivity images, and their geological interpretation, show a dissected Mesozoic-Tertiary substratum buried under continental infill of mainly Quaternary age due to the long-term activity of the Paganica-San Demetrio normal faults system (PSDFS), ruling the most recent deformational phase. Our results indicate that the basin bottom deepens up to 600 m moving to the south, with the continental infill largely exceeding the known thickness of the Quaternary sequence. The causes of this increasing thickness can be: (1) the onset of the continental deposition in the southern sector took place before the Quaternary, (2) there was an early stage of the basin development driven by different fault systems that produced a depocentre in the southern sector not related to the present-day basin shape, or (3) the fault system slip rate in the southern sector was faster than in the northern sector. We were able to gain sights into the long-term PSDFS behaviour and evolution, by comparing throw rates at different timescales and discriminating the splays that lead deformation. Some fault splays exhibit large cumulative throws (>300 m) in coincidence with large displacement of the continental deposits sequence (>100 m), thus testifying a general persistence in time of their activity as leading splays of the fault system. We evaluate the long-term (3-2.5 Myr) cumulative and Quaternary throw rates of most of the leading splays to be 0.08-0.17 mm yr-1, indicating a substantial stability of the faults activity. Among them, an individual leading fault splay extends from Paganica to San Demetrio ne' Vestini as a result of a post-Early Pleistocene linkage of

  1. Eddy covariance measurements of ozone fluxes at 4 levels above and within a forest canopy in the Po valley (Italy) (United States)

    Gerosa, Giacomo; Finco, Angelo; Marzuoli, Riccardo; Coyle, Mhairi; Nemitz, Eiko


    In June and July 2012, during the intensive field campaign of the ECLAIRE project, ozone fluxes as well as sensible heat and momentum fluxes were measured at four different levels at the Bosco Fontana site, a 26 m tall mixed oak-hornbeam forest in the Po valley (I). Each measuring level (41 m, 32 m, 24 m and 16 m) was equipped with a sonic anemometer and a fast ozone analyser, absolute ozone concentrations were measured by means of a UV photometer. Additional meteorological parameters were measured on the top and at each level and ozone concentrantions were measured at ground level (0.15 m) by another UV photometer. In order to compare measurements collected with different instruments, data were preliminary processed and the following methodology were applied: despiking, instantaneous rotations, WPL corrections, frequency loss corrections and calculation of the random error. The main aims of this field campaign were the description of the deposition processes within and above canopy and the test of the constant flux hypothesis. About this latter interesting features emerged: the conservation of the flux was valid for the momentum only outside the canopy and no conservation was observed for the sensible heat. On the contrary ozone fluxes showed a much more irregular behaviour: for the three upper levels, ozone fluxes were nearly constant in the first hours of the day while an enhancement of the fluxes was observed at 24 m. This latter fact was strictly linked with the in-canopy dynamics: a greater heating of the canopy was observed in the afternoon, leading to the formation of an inversion at this level. This inversion divided the in-canopy air volume into two layers: the lower one with a stable stratification and the upper one with a turbulent regime; as a consequence of this inversion a remarkable reduction of the ozone concentration was observed for the two lowest levels in the afternoon, when in the lowest layers ozone is consumed by NO emissions from soil.

    Wadim Jaeger


    Full Text Available In the present paper, an uncertainty and sensitivity study is performed for transient void fraction and pressure drop measurements. Two transients have been selected from the NUPEC BFBT database. The first one is a turbine trip without bypass and the second one is a trip of a recirculation pump. TRACE (version 5.0 patch 2 is used for the thermohydraulic study and SUSA and DAKOTA are used for the quantification of the model uncertainties and the evaluation of the sensitivities. As uncertain parameters geometrical values, hydraulic diameter, and wall roughness are considered while mass flow rate, power, pressure, and inlet subcooling (inlet temperature are chosen as boundary and input conditions. Since these parameters change with time, it is expected that the importance of them on pressure drop and void fraction will change, too. The results show that the pressure drop is mostly sensitive to geometrical variations like the hydraulic diameter and the form loss coefficient of the spacer grid. For low void fractions, the parameter of the highest importance is the inlet temperature/subcooling while at higher void fraction the power is also of importance.

    Full Text Available Fine particulate matter (PM levels and resulting impacts on human health are in the Po Valley (Italy among the highest in Europe. To build effective PM abatement strategies, it is necessary to characterize fine PM chemical composition, sources and atmospheric processes on long timescales (> months, with short time resolution (< day, and with particular emphasis on the predominant organic fraction. Although previous studies have been conducted in this region, none of them addressed all these aspects together. For the first time in the Po Valley, we investigate the chemical composition of nonrefractory submicron PM (NR-PM1 with a time resolution of 30 min at the regional background site of Ispra during 1 full year, using the Aerodyne Aerosol Chemical Speciation Monitor (ACSM under the most up-to-date and stringent quality assurance protocol. The identification of the main components of the organic fraction is made using the Multilinear-Engine 2 algorithm implemented within the latest version of the SoFi toolkit. In addition, with the aim of a potential implementation of ACSM measurements in European air quality networks as a replacement of traditional filter-based techniques, parallel multiple offline analyses were carried out to assess the performance of the ACSM in the determination of PM chemical species regulated by air quality directives. The annual NR-PM1 level monitored at the study site (14.2 µg m−3 is among the highest in Europe and is even comparable to levels reported in urban areas like New York City and Tokyo. On the annual basis, submicron particles are primarily composed of organic aerosol (OA, 58 % of NR-PM1. This fraction was apportioned into oxygenated OA (OOA, 66 %, hydrocarbon-like OA (HOA, 11 % of OA and biomass burning OA (BBOA, 23 %. Among the primary sources of OA, biomass burning (23 % is thus bigger than fossil fuel combustion (11 %. Significant contributions of aged secondary organic aerosol (OOA

  5. Variability of Black Carbon and Ultrafine Particle Concentration on Urban Bike Routes in a Mid-Sized City in the Po Valley (Northern Italy

    Full Text Available Cyclists might experience increased air pollution exposure, due to the proximity to traffic, and higher intake, due to their active travel mode and higher ventilation. Several local factors, like meteorology, road and traffic features, and bike lanes features, affect cyclists’ exposure to traffic-related pollutants. This paper investigates the concentration levels and the effect of the features of the bike lanes on cyclists’ exposure to airborne ultrafine particulate matter (UFP and black carbon (BC in the mid-sized city of Piacenza, located in the middle of the Po Valley, Northern Italy. Monitoring campaigns were performed by means of portable instruments along different urban bike routes with bike lanes, characterized by different distances from the traffic source (on-road cycle lane, separated cycle lane, green cycle path, during morning (9:00 am–10:00 am and evening (17:30 pm–18:30 pm workday rush hours in both cold and warm seasons. The proximity to traffic significantly affected cyclists’ exposure to UFP and BC: exposure concentrations measured for the separated lane and for the green path were 1–2 times and 2–4 times lower than for the on-road lane. Concurrent measurements showed that exposure concentrations to PM10, PM2.5, and PM1 were not influenced by traffic proximity, without any significant variation between on-road cycle lane, separated lane, or green cycle path. Thus, for the location of this study PM mass-based metrics were not able to capture local scale concentration gradients in the urban area as a consequence of the rather high urban and regional background that hides the contribution of local scale sources, such as road traffic. The impact of route choice on cyclists’ exposure to UFPs and BC during commuting trips back and forth from a residential area to the train station has been also estimated through a probabilistic approach through an iterative Monte Carlo technique, based on the measured data.

  6. Primary and secondary biomass burning aerosols determined by proton nuclear magnetic resonance (1H-NMR) spectroscopy during the 2008 EUCAARI campaign in the Po Valley (Italy) (United States)

    Paglione, M.; Saarikoski, S.; Carbone, S.; Hillamo, R.; Facchini, M. C.; Finessi, E.; Giulianelli, L.; Carbone, C.; Fuzzi, S.; Moretti, F.; Tagliavini, E.; Swietlicki, E.; Eriksson Stenström, K.; Prévôt, A. S. H.; Massoli, P.; Canaragatna, M.; Worsnop, D.; Decesari, S.


    Atmospheric organic aerosols are generally classified as primary and secondary (POA and SOA) according to their formation processes. An actual separation, however, is challenging when the timescales of emission and gas-to-particle formation overlap. The presence of SOA formation in biomass burning plumes leads to scientific questions about whether the oxidized fraction of biomass burning aerosol is rather of secondary or primary origin, as some studies would suggest, and about the chemical compositions of oxidized biomass burning POA and SOA. In this study, we apply nuclear magnetic resonance (NMR) spectroscopy to investigate the functional group composition of fresh and aged biomass burning aerosols during an intensive field campaign in the Po Valley, Italy. The campaign was part of the EUCAARI project and was held at the rural station of San Pietro Capofiume in spring 2008. Factor analysis applied to the set of NMR spectra was used to apportion the wood burning contribution and other organic carbon (OC) source contributions, including aliphatic amines. Our NMR results, referred to the polar, water-soluble fraction of OC, show that fresh wood burning particles are composed of polyols and aromatic compounds, with a sharp resemblance to wood burning POA produced in wood stoves, while aged samples are clearly depleted of alcohols and are enriched in aliphatic acids with a smaller contribution of aromatic compounds. The comparison with biomass burning organic aerosols (BBOA) determined by high-resolution aerosol mass spectrometry (HR-TOF-AMS) at the site shows only a partial overlap between NMR BB-POA and AMS BBOA, which can be explained by either the inability of BBOA to capture all BB-POA composition, especially the alcohol fraction, or the fact that BBOA account for insoluble organic compounds unmeasured by the NMR. Therefore, an unambiguous composition for biomass burning POA could not be derived from this study, with NMR analysis indicating a higher O / C ratio

    Full Text Available Abstract The study was conducted on a pair of otters (Lutra lutra housed in an enclosure of 1.64 ha, located within a wet wood in the Natural Park of the Ticino Valley (northern Italy, Piemonte region. This enclosure contained two ponds (0.2 and 0.45 ha with fairly good cover vegetation, where a fish biomass of 201.5 kg/ha, represented by 14 fish species, was assessed by electrofishing. Though the food supply for otter was fairly good, the animals were daily fed with 1.5 kg of chicks, meat or rainbow trout (Salmo gairdneri. In order to evaluate the habitat selection of otters, the enclosure was divided into 15 environmental units (EU. Hunting, swimming and playing (exclusively in pair were the main behavioural activities and were preferentially performed close to the ponds' bank, where a thick cover occurred. Otters selected patches for foraging where fish was concentrated and particularly vulnerable to predation. The hunting impact in a given EU (defined as ratio between the number of prey caught in the EU and the total number of prey was correlated with the hunting time spent in the same EU. Habitat use evaluated by direct observations differed from that determined by considering the marking level (number of spraints and anal secretions. The consumption of the different fish species did not seem to be determined by their relative abundance. Perca fluviatilis was particularly selected.

    Full Text Available Abstract The presence of the Eurasian lynx (Lynx lynx L. 1758 was revealed during an investigation performed from I991 to 1994 in three contiguous valleys (Antigorio valley, Formazza valley and Devero valley of the Verbania province in Piemonte. In this investigation two methods were employed: interviews with the people who saw a lynx and/or found evidence of its presence (prints, faeces, scratchings on trees and meal remains and field research by means of line transects, as reported by Ragni et al. (1993. The research area was of about 250 km². Lynx signs were obtained in 1991, 1992 and 1994 between 600 and 1800 m a.s.1. and during all seasons. The lynx was usually observed at night and at dusk. The research shows that the Eurasian lynx is present, although sporadically, in this area of the western Italian Alps.

  12. Chronostratigraphic study of the Grottaperfetta alluvial valley in the city of Rome (Italy: investigating possible interaction between sedimentary and tectonic processes

    Directory of Open Access Journals (Sweden)

    G. Di Giulio


    Full Text Available We carried out geomorphologic and geological investigations in a south-eastern tributary valley of the Tiber River in Rome, the Grottaperfetta valley, aimed to reconstruct its buried geometry. Since results of the geomorphologic study evidenced anomalies of the stream beds, we performed geoelectric and boreholes prospecting to check whether recent faulting, rather than an inherited structural control, possibly contributed to the evolution of the alluvial valley. Vertical offsets of the stratigraphic horizons across adjacent boreholes were evidenced within the Late Pleistocene-Holocene alluvium and its substratum. In order to rule out the effects of irregular geometry of the alluvial deposits, we focussed on sectors where vertical offsets affected all the stratigraphic horizons (alluvium and pre-Holocene substratum, showing an increasing displacement with depth. We identified a site where repeated displacements occur coupled with a lateral variation of soil resistivity, and we drilled an oblique borehole aimed to cross and sample the possible fault zone affecting the terrain. A 7 cm thick granular layer, inclined 50°÷70° on the horizontal, was recovered 5 m b.g., and it was interpreted as the filling material of a fracture. The convergence of the reported features with independent evidence from geoelectric and geomorphologic investigations leads to hypothesize the presence of a faulting zone within the Holocene alluvial terrains and to propose the excavation of a trench to verify this hypothesis.

  13. Trends and variability of atmospheric PM2.5 and PM10-2.5 concentration in the Po Valley, Italy (United States)

    Bigi, Alessandro; Ghermandi, Grazia


    The Po Valley is one of the largest European regions with a remarkably high concentration level of atmospheric pollutants, both for particulate and gaseous compounds. In the last decade stringent regulations on air quality standards and on anthropogenic emissions have been set by the European Commission, including also for PM2.5 and its main components since 2008. These regulations have led to an overall improvement in air quality across Europe, including the Po Valley and specifically PM10, as shown in a previous study by Bigi and Ghermandi (2014). In order to assess the trend and variability in PM2.5 in the Po Valley and its role in the decrease in PM10, we analysed daily gravimetric equivalent concentration of PM2.5 and of PM10-2.5 at 44 and 15 sites respectively across the Po Valley. The duration of the times series investigated in this work ranges from 7 to 10 years. For both PM sizes, the trend in deseasonalized monthly means, annual quantiles and in monthly frequency distribution was estimated: this showed a significant decreasing trend at several sites for both size fractions and mostly occurring in winter. All series were tested for a significant weekly periodicity (a proxy to estimate the impact of primary anthropogenic emissions), yielding positive results for summer PM2.5 and for summer and winter PM10-2.5. Hierarchical cluster analysis showed moderate variability in PM2.5 across the valley, with two to three main clusters, dividing the area in western, eastern and southern/Apennines foothill sectors. The trend in atmospheric concentration was compared with the time series of local emissions, vehicular fleet details and fuel sales, suggesting that the decrease in PM2.5 and in PM10 originates from a drop both in primary and in precursors of secondary inorganic aerosol emissions, largely ascribed to vehicular traffic. Potentially, the increase in biomass burning emissions in winter and the modest decrease in NH3 weaken an otherwise even larger drop in

  14. Contrasting mass-wasting activity in two debris flow-dominated catchments of the Venosta Valley/Vinschgau (Italy): 1945-2014 (United States)

    Lazzarini, Simone; Brardinoni, Francesco; Draganits, Erich; Cavalli, Marco


    Debris flows are the most common mass movements within alpine mountainous catchments and main responsible process for sediment delivery from headwaters to streams. Often the delivered unsorted material accumulates as debris-flow lobes on the large debris-flow fans occurring at the outlet of secondary valleys or where the slope becomes less steep. These mass-wasting events are remarkable hazardous process concerning infrastructure and people, especially if villages are located on such fans. Therefore monitoring and analysis of the debris-flow activity is essential in order to mitigate the risk. This study presents the results of a multi-temporal analysis of the debris flow activity and the evolution of the colluvial sediment sources over the last 70 years. Two high-altitude watersheds, close to each other in the Venosta valley (Eastern Italian Alps), were geomorphologically characterized and the transport regimes were identified. The larger basin is Cengles Creek (10.7 km2) and the smaller watershed is Plaies Creek (3.6 km2). The analysis has been carried out using historical aerial photos and digital analogues as well as through geomorphological, sedimentological and hydrological fieldwork. Our results consist of the identification of different geomorphological features and debris-flow activity patterns within the two basins. The Cengles basin is characterized by a diffuse layer of permafrost, a hanging valley floor where alluvial processes predominate and considerable vegetation. Within this catchment the debris-flow activity has been quite stable over the last seven decades, with peak activities related to exceptional events, for example in 1999. On the other hand, the Plaies watershed possesses diffuse steep slopes, virtually no vegetation and a large glacier at its headwaters; also there the mass-wasting activity shows a stable trend with an only exceptional peak, linked to the occurrence of a large event in August 2012. The processes in the catchment area

    Ambrosia is an annual anemophilous weed producing allergenic pollen affecting public health in European countries. In Italy, the most infested region is Lombardy where, in some areas, it is the major cause of hay fever. In the Parma district, until 2007, Ambrosia seemed to be very rare, despite an observed increase of Seasonal Pollen Index (SPI), of pollen peak value and of asthma among ragweed sensitized patients. The aims of this study were to calculate ragweed pollen season and trends from 1996 to 2015, to assess the relationships between pollen season characteristics and selected meteorological data, to map plants in the territory and to evaluate the presence of beetle Ophraella communa (Ophraella), known as an eater of Ambrosia leaves. The following pollination parameters: start, end, duration, peak concentration date, peak values, SPI and the following climatic parameters: temperature, relative humidity, rainfall, were analyzed. The ragweed plants sites were mapped and the presence of Ophraella was assessed during naturalistic activities. Significant SPI and pollen peak value increase until 2011 were observed, but recently, 2012-2015 vs 2009-2011, a strong reduction (about 50%) of these parameters was observed. The spring average air temperature increased significantly. The results of the correlation analysis showed Ambrosia season characteristics significantly related. We identified the sites source of Ambrosia, even downtown at the confluence between Parma and Baganza rivers. Ophraella was observed for the first time in 2014. The results showed the spread of ragweed plants over the territory and the risk of allergy increase that ragweed could cause. It remains to evaluate the role of the Ophraella in the reduction of Ambrosia pollen concentration. It is important to consider the potential risk Ophraella may represent for sunflower and other taxonomically related crop plants and other native and exotic species. The lack of initiatives by the Health

  16. Imaging the Shallow Crust in the Epicentral Area of the 1857 M7 Agri Valley Earthquake (Southern Italy) by Combined Traveltime and Full-Waveform Tomography (United States)

    Improta, L.; Operto, S.; Piromallo, C.; Valoroso, L.


    The Agri Valley is a Quaternary extensional basin located in the Southern Apennines range. This basin was struck by a M7 earthquake in 1857. In spite of extensive morphotectonic surveys and hydrocarbon exploration, major unsolved questions remain about the upper crustal structure, the recent tectonic evolution and seismotectonics of the area. Most authors consider a SW-dipping normal-fault system bordering the basin to the East as the major seismogenic source. Alternatively, some authors ascribe the high seismogenic potential of the region to NE-dipping normal faults identified by morphotectonic surveys along the ridge bounding the basin to the West. These uncertainties mainly derive from the poor performance of commercial reflection profiling that suffers from an extreme structural complexity and unfavorable near-surface conditions. To overcome these drawbacks, ENI and Shell Italia carried out a non-conventional wide-aperture survey with densely spaced sources (60 m) and receivers (90 m). The 18-km-long wide-aperture profile crosses the basin, yielding a unique opportunity to get new insights into the crustal structure by using advanced imaging techniques. Here, we apply a two-step imaging procedure. We start determining multi- scale Vp images down to 2.5 km depth by using a non-linear traveltime tomographic technique able to cope with strongly heterogeneous media. Assessment of an accurate reference Vp model is indeed crucial for the subsequent application of a frequency-domain full-waveform inversion aimed at improving spatial resolution of the velocity images. Frequency components of the data are then iteratively inverted from low to high frequency values in order to progressively incorporate smaller wavelength components into the model. Inversion results accurately image the shallow crust, yielding valuable constraints for a better understanding of the recent basin evolution and of the surrounding normal-fault systems.

  17. Morpho-structural evolution of the valley-slope systems and related implications on slope-scale gravitational processes: New results from the Mt. Genzana case history (Central Apennines, Italy) (United States)

    Della Seta, M.; Esposito, C.; Marmoni, G. M.; Martino, S.; Scarascia Mugnozza, G.; Troiani, F.


    This work is aimed at constraining a slope-scale, deep-seated gravitational slope deformation (DSGSD) and an associated rockslide-avalanche in the frame of the Quaternary morpho-structural evolution of Central Apennines (Italy). The study area is the western slope of the Mt. Genzana calcareous ridge, for which a conceptual slope evolutionary model had been already proposed. The existing model has highlighted the role of inherited geological-structural setting combined with Quaternary morpho-evolution in the onset of rock-slope deformational processes until paroxysmal phases (i.e. occurrence of massive rock slope failures). In this work, the previous conceptual evolutionary model was strengthened and detailed by means of a mid-term landscape evolution model, based on the study of geomorphic markers hanging at different elevations above the present valley floor. The Quaternary landscape evolution was also constrained by means of time-dependent landscape metrics. Consequently, it was possible to back-analyse the observed DSGSD process from its onset up to the occurrence of localized massive rock slope failures, through a time-dependent stress-strain numerical modeling. The results of such a multi-modeling approach: i) highlighted the importance of rock mass creep during some stages of the morpho-evolution; ii) pointed out the relevant role of the inherited structural pattern in identifying the preferential strain concentration zones and failure surfaces; and iii) confirmed the hypothesis that the Scanno rockslide-avalanche scar is the result of two separate failure events, as an initial landslide involving the lower part of the slope that favoured a subsequent failure in the upper part of the slope.

  18. A multidisciplinary approach to reveal floodplain palaeohydrography in the surrounding of ancient Luna archaeological site (lower Magra River valley, NW Italy) (United States)

    Bini, Monica; Bisson, Marina; Chelli, Alessandro; Pappalardo, Marta


    The Magra floodplain (NW Italy) is a coastal plain that was created during the last 2.5 millennia by the River Magra itself and by minor streams draining the southern slope of the Apuan Alps. The coastline progressively migrated from the mountain foothills to its present position, 2.5 km seaward. Available stratigraphical data suggest that the marine gulf that occupied the area before Bronze age gradually changed into a lagoon; this was finally separated from the open sea and became a complex of marshes that were finally silted up. All these environments provided opportunities for settlement and land use: early settlement is accounted for in the Iron Age by Ligurian people that were finally defeated by the Romans. In the 2nd century bC the roman colony of Luna (today Luni) was founded in the area. After the Imperial Age Luni gradually decayed and was finally abandoned in 1204. Post-Roman alluviation is thought to be partly responsible for the city decline and the survival of only scattered farmsteads in its surroundings. Settlement and land use history from Iron Age onward are thus tightly dependant from drainage network evolution in the area. Although historical maps provide some chronological constraints about the advance of the Magra floodplain it is still unknown how and when precisely the transformation of a lagoon environment into a dry land occurred. In particular no data are available about the position of the mouths of the Magra River and of the minor streams at Roman Times and little is known about channel migration since the Early Middle Ages and information about land reclamation are difficult to find because dispersed. In order to identify abandoned fluvial channels, a series of digital elaborations were applied to different types of Remotely-Sensed Images. In detail, the used data consist of satellite images (Landsat 7 - ETM) and airborne orthophotos (AIMA) covering a temporal interval of five years (from 1998 to 2002) and characterized by a spatial

  19. Time-variant risk assessment of a hazard cascade at the example of a rockslide dam - a case study in the Upper Val Venosta / Vinschgau Valley, Italy (United States)

    Kofler, Christian; Renner, Kathrin; Comiti, Francesco; Gems, Bernhard; Schneiderbauer, Stefan; Thiebes, Benni; Schlögel, Romy


    Earthquakes and heavy precipitation events represent the main triggering factors of mass movements such as landslides, rockslides or debris flows. The overall hazard potential is increased significantly if the mass movement subsequently interacts with an adjacent river course by creating a fully or partially blockage of the channel. These temporary dams can cause disastrous secondary hazards by backwater inundation or outburst floods. Therefore, the formation and failure of rockslide dams can be regarded and assessed as a cascade of hazards. Through the cascading effects, rockslide dams can affect areas at great distances up -or downstream of the site where the actual mass movement occurred. Moreover, the time span between the generation and the failure of a rockslide dam can vary from few minutes to several days or even decades. This type of cascading hazard is therefore subject to high temporal and spatial variability. Due to the difficulties assessing the probabilities of each part of the hazard cascade, there is a substantial uncertainty involved in the assessment of the overall hazard. Risk assessments, however, often do not account for this complexity when assessing the exposed elements. Especially the exposure of people, highly mobile in space and time, is often not taken into consideration. In this study, we propose a novel approach that combines both the dynamic components of the hazard and the exposure. The study area extends over the two municipalities of Stilfs/Stelvio and Prad am Stilsferjoch/Prato allo Stelvio in the Autonomous Province of Bozen/Bolzano (South Tyrol) in Northern Italy. Both municipalities are major tourist destinations in the region featuring two ski resorts, a national park and the well-known 'Stilfser Joch/Passo dello Stelvio' mountain pass. This implies a high daily and seasonal fluctuation of people, including commuters and tourists. The upper part of the slope above the village of Trafoi is at risk of a sudden failure of a large

    Full Text Available Road traffic is a serious problem in the Chamonix Valley, France: traffic, noise and above all air pollution worry the inhabitants. The big fire in the Mont-Blanc tunnel made it possible, in the framework of the POVA project (POllution in Alpine Valleys, to undertake measurement campaigns with and without heavy-vehicle traffic through the Chamonix and Maurienne valleys, towards Italy (before and after the tunnel re-opening. Modelling is one of the aspects of POVA and should make it possible to explain the processes leading to episodes of atmospheric pollution, both in summer and in winter. Atmospheric prediction model ARPS 4.5.2 (Advanced Regional Prediction System, developed at the CAPS (Center for Analysis and Prediction of Storms of the University of Oklahoma, enables to resolve the dynamics above a complex terrain. This model is coupled to the TAPOM 1.5.2 atmospheric chemistry (Transport and Air POllution Model code developed at the Air and Soil Pollution Laboratory of the Ecole Polytechnique Fédérale de Lausanne. The numerical codes MM5 and CHIMERE are used to compute large scale boundary forcing. This paper focuses on modelling Chamonix valley using 300-m grid cells to calculate the dynamics and the reactive chemistry which makes possible to accurately represent the dynamics in the Chamonix valley (slope and valley winds and to process chemistry at fine scale. The summer 2003 intensive campaign was used to validate the model and to study chemistry. NOy according to O3 reduction demonstrates a VOC controlled regime, different from the NOx controlled regime expected and observed in the nearby city of Grenoble.

    Petroff, Alexander P; Abrams, Daniel M; Lobkovsky, Alexander E; Kudrolli, Arshad; Rothman, Daniel H


    Although amphitheater-shaped valley heads can be cut by groundwater flows emerging from springs, recent geological evidence suggests that other processes may also produce similar features, thus confounding the interpretations of such valley heads on Earth and Mars. To better understand the origin of this topographic form we combine field observations, laboratory experiments, analysis of a high-resolution topographic map, and mathematical theory to quantitatively characterize a class of physical phenomena that produce amphitheater-shaped heads. The resulting geometric growth equation accurately predicts the shape of decimeter-wide channels in laboratory experiments, 100-meter wide valleys in Florida and Idaho, and kilometer wide valleys on Mars. We find that whenever the processes shaping a landscape favor the growth of sharply protruding features, channels develop amphitheater-shaped heads with an aspect ratio of pi.

  9. Intermontane valley fills


    Mey, Jürgen (Diplom-Geologe)


    Sedimentary valley fills are a widespread characteristic of mountain belts around the world. They transiently store material over time spans ranging from thousands to millions of years and therefore play an important role in modulating the sediment flux from the orogen to the foreland and to oceanic depocenters. In most cases, their formation can be attributed to specific fluvial conditions, which are closely related to climatic and tectonic processes. Hence, valley-fill deposits constitute v...

    Professional exposure to asbestos fibres is widely recognized as very dangerous to human health and for this reason many countries have banned their commercial uses. People, nevertheless, continue to be exposed to low dose of asbestos from natural and anthropogenic sources still in loco, for which the potential hazard is unknown. The aim of this research is to assess environmental exposure in an area with outcropping serpentinite rocks, which bear asbestos mineralizations, using sentinel animals which are a non-experimental animal model. We studied the burden of inorganic fibres in cattle lungs which come from two areas in Italy's Western Alps bearing serpentinitic outcrops: Susa Valley with a heavy anthropization and Lanzo Valleys, with a minor human impact. The identification and quantification of inorganic fibres were performed by Scanning Electron Microscope (SEM) and Energy Dispersive Spectrometer (EDS). In comparison to humans, studies of animals have some advantages, such as no occupational exposure or history of smoking and, in the case of cattle, a sedentary life restricted to one region. Results spotlight that over than 35% of inorganic fibres found both in Susa and Lanzo valleys, belong to asbestos mineralogical species (asbestos tremolite/actinolite, chrysotile s.s., asbestos grunerite, crocidolite). We also observed a higher concentration of artificial fibrous products in Susa samples showing a correlation with the level of anthropization. These results confirm that sentinel animals are an excellent model to assess breathable environmental background because it is possible to eliminate some variables, such as unknown occupational exposure.

  12. Biogerontology in Italy. (United States)

    Odetti, Patrizio; Bergamini, Ettore


    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.

  13. Religious slaughter in Italy. (United States)

    Cenci-Goga, B T; Mattiacci, C; De Angelis, G; Marini, P; Cuccurese, A; Rossi, R; Catanese, B


    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.

  18. Bringing Silicon Valley inside. (United States)

    Hamel, G


    In 1998, Silicon Valley companies produced 41 IPOs, which by January 1999 had a combined market capitalization of $27 billion--that works out to $54,000 in new wealth creation per worker in a single year. Multiply the number of employees in your company by $54,000. Did your business create that much new wealth last year? Half that amount? It's not a group of geniuses generating such riches. It's a business model. In Silicon Valley, ideas, capital, and talent circulate freely, gathering into whatever combinations are most likely to generate innovation and wealth. Unlike most traditional companies, which spend their energy in resource allocation--a system designed to avoid failure--the Valley operates through resource attraction--a system that nurtures innovation. In a traditional company, people with innovative ideas must go hat in hand to the guardians of the old ideas for funding and for staff. But in Silicon Valley, a slew of venture capitalists vie to attract the best new ideas, infusing relatively small amounts of capital into a portfolio of ventures. And talent is free to go to the companies offering the most exhilarating work and the greatest potential rewards. It should actually be easier for large, traditional companies to set up similar markets for capital, ideas, and talent internally. After all, big companies often already have extensive capital, marketing, and distribution resources, and a first crack at the talent in their own ranks. And some of them are doing it. The choice is yours--you can do your best to make sure you never put a dollar of capital at risk, or you can tap into the kind of wealth that's being created every day in Silicon Valley.

  19. Wine tourism in Italy

    Directory of Open Access Journals (Sweden)

    Cinelli Colombini D


    Full Text Available Donatella Cinelli Colombini Orcia Doc Wine Consortium, Rocca d’Orcia , Italy Abstract: This text includes the history of wine tourism in Italy since 1993, when the first edition of the event “Cantine Aperte” (Open Cellars, Wine Day, took place. 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

  20. Conscientious objection in Italy. (United States)

    Minerva, Francesca


    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.

  1. Green valley galaxies

    Directory of Open Access Journals (Sweden)

    Salim S.


    Full Text Available The “green valley” is a wide region separating the blue and the red peaks in the ultraviolet-optical color magnitude diagram, first revealed using GALEX UV photometry. The term was coined by Christopher Martin (Caltech, in 2005. Green valley highlights the discriminating power of UV to very low relative levels of ongoing star formation, to which the optical colors, including u−r, are insensitive. It corresponds to massive galaxies below the star-forming, “main” sequence, and therefore represents a critical tool for the study of the quenching of star formation and its possible resurgence in otherwise quiescent galaxies. This article reviews the results pertaining to (predominantly disk morphology, structure, environment, dust content and gas properties of green valley galaxies in the local universe. Their relationship to AGN is also discussed. Attention is given to biases emerging from defining the “green valley” using optical colors. We review various evolutionary scenarios and we present evidence for a new one, the quasi-static view of the green valley, in which the majority (but not all of galaxies currently in the green valley were only partially quenched in the distant past and now participate in a slow cosmic decline of star formation, which also drives down the activity on the main sequence, presumably as a result of the dwindling accretion/cooling onto galaxy disks. This emerging synthetic picture is based on the findings from Fang et al. (2012, Salim et al. (2012 and Martin et al. (2007, as well as other results.

  2. Fluvial valleys and Martian palaeoclimates (United States)

    Gulick, Virginia C.; Baker, Victor R.


    Theoretical models of early Martian atmospheric evolution describe the maintenance of a dense CO2 atmosphere and a warm, wet climate until the end of the heavy-bombardment phase of impacting. However, the presence of very young, earthlike fluvial valleys on the northern flank of Alba Patera conflicts with this scenario. Whereas the widespread ancient Martian valleys generally have morphologies indicative of sapping erosion by the slow outflow of subsurface water, the local Alba valleys were probably formed by surface-runoff processes. Because subsurface water flow might be maintained by hydrothermal energy inputs and because surface-runoff valleys developed late in Martian history, it is not necessary to invoke drastically different planet-wide climatic conditions to explain valley development on Mars. The Alba fluvial valleys can be explained by hydrothermal activity or outflow-channel discharges that locally modified the atmosphere, including precipitation and local overland flow on low-permeability volcanic ash.

  3. Optical manipulation of valley pseudospin (United States)

    Ye, Ziliang; Sun, Dezheng; Heinz, Tony F.


    The coherent manipulation of spin and pseudospin underlies existing and emerging quantum technologies, including quantum communication and quantum computation. Valley polarization, associated with the occupancy of degenerate, but quantum mechanically distinct valleys in momentum space, closely resembles spin polarization and has been proposed as a pseudospin carrier for the future quantum electronics. Valley exciton polarization has been created in the transition metal dichalcogenide monolayers using excitation by circularly polarized light and has been detected both optically and electrically. In addition, the existence of coherence in the valley pseudospin has been identified experimentally. The manipulation of such valley coherence has, however, remained out of reach. Here we demonstrate all-optical control of the valley coherence by means of the pseudomagnetic field associated with the optical Stark effect. Using below-bandgap circularly polarized light, we rotate the valley exciton pseudospin in monolayer WSe2 on the femtosecond timescale. Both the direction and speed of the rotation can be manipulated optically by tuning the dynamic phase of excitons in opposite valleys. This study unveils the possibility of generation, manipulation, and detection of the valley pseudospin by coupling to photons.

  4. [Social cooperatives in Italy]. (United States)

    Villotti, P; Zaniboni, S; Fraccaroli, F


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

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

  9. Syenite and diorite: a unique stone heritage in north of Italy (United States)

    Tori, Alice; Marini, Paula; Zichella, Lorena; Bellopede, Rossana


    The Syenite from the Cervo Torrent Valley near Biella in northern Italy has been widely used as a building material. During the XXth century it has been exported all over the World for covering and paving slabs and monumental work. It is an intrusive magmatic rock found in the Cervo Valley pluton, which is part of the Balma pluton. It formed about 30 million years ago as a result of the Alpine Orogeny and is known to be post-orogenic because of the absence of metamorphism. Hydrothermal mineralization associated with the pluton includes minerals of molybdenum, tungsten, copper, lead, silver and gold. Utilisation of the Syenite has been the only industrial activity in the high Cervo Valley sustaining the whole of valley life. During the second half of the XIXth century and during the first part of the XXth the competencies and the working skills of the Cervo Valley stonecutters was exported as far as Perù and China. It was e.g. used for the edification and refinement of the Oropa Sanctuary square in Piedmont, Italy. It has been recognized as an interesting building material because of the intrinsic characteristics such as its resistance to mechanical wear, durability of colour tone and intensity and resistance to water wear (e.g. in fountains) and maintains its mechanical integrity over time. Diorite is also a magmatic intrusive rock and, similar to the syenite, differs from granite due to the low concentration of quartz (cut and to process with the suitable tools. It has a number of variants, each with specific characteristics and behavior. It is multipurpose material and consequently it can be used in different shape and application, such as slabs, covering, bed river, building block and tiles. Although mainly used in Italy, it has also been used world wide for many different constructional and aesthetic purposes. These two stones from the Canavase area have an interesting history and a wide range of uses.

  10. Cases of bed bug (Cimex lectularius infestations in Northwest Italy

    Directory of Open Access Journals (Sweden)

    Federica Giorda


    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.

  14. Gestalt psychology in Italy. (United States)

    Verstegen, I


    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. Polycyclic aromatic hydrocarbons (PAHs in the atmospheres of two French alpine valleys: sources and temporal patterns

    Directory of Open Access Journals (Sweden)

    N. Marchand


    Full Text Available Alpine valleys represent some of the most important crossroads for international heavy-duty traffic in Europe, but the full impact of this traffic on air quality is not known due to a lack of data concerning these complex systems. As part of the program "Pollution des Vallées Alpines" (POVA, we performed two sampling surveys of polycyclic aromatic hydrocarbons (PAHs in two sensitive valleys: the Chamonix and Maurienne Valleys, between France and Italy. Sampling campaigns were performed during the summer of 2000 and the winter of 2001, with both periods taking place during the closure of the "Tunnel du Mont-Blanc". The first objective of this paper is to describe the relations between PAH concentrations, external parameters (sampling site localization, meteorological parameters, sources, and aerosol characteristics, including its carbonaceous fraction (OC and EC. The second objective is to study the capacity of PAH profiles to accurately distinguish the different emission sources. Temporal evolution of the relative concentration of an individual PAH (CHR and the PAH groups BghiP+COR and BbF+BkF is studied in order to differentiate wood combustion, gasoline, and diesel emissions, respectively. The results show that the total particulate PAH concentrations were higher in the Chamonix valley during both seasons, despite the cessation of international traffic. Seasonal cycles, with higher concentrations in winter, are also stronger in this valley. During winter, particulate PAH concentration can reach very high levels (up to 155 ng.m-3 in this valley during cold anticyclonic periods. The examination of sources shows the impact during summer of heavy-duty traffic in the Maurienne valley and of gasoline vehicles in the Chamonix valley. During winter, Chamonix is characterized by the strong influence of wood combustion in residential fireplaces, even if the temporal evolution of specific PAH ratios are difficult to interpret.

    Full Text Available This study presents some of the results of 18 years of research in the Albegna Valley/Ager Cosanus area, Tuscany, Italy. Thousands of artefacts have been collected and hundreds of sites recorded during this period by systematic field survey. The Albegna Valley/Ager Cosanus Survey was directed by Professor Andrea Carandini, now of the University of Rome, La Sapienza, and Professor Elisabeth Fentress, now of the American Academy at Rome. The project is a collaboration between scholars of many institutions in Italy, France and Britain and the first volume of the final report detailing and interpreting the sites located is now in press (Cambi et al, forthcoming. This study concentrates upon a part of the finds made during field walking: the ceramics dating to the Etruscan period (8th-3rd century BC. The collection largely consists of finewares, coarsewares and amphorae. Together with the study of the ceramics from the Etruscan city at Doganella (Perkins and Walker 1990, and the excavated Etruscan farm at Podere Tartuchino (Attolini and Perkins 1992, both also in the Albegna Valley, the present study forms the most extensive detailed study of Etruscan ceramics from settlements identified by systematic survey that has been made to date. Collections from individual sites have been published in the past but the Albegna Valley/Ager Cosanus is the first part of Etruria, investigated at a regional scale, where the Etruscan ceramics have been fully studied and published. The first part of the study is an account of the fieldwork and the sampling strategy which was used during the collection of the ceramics presented here. This is followed by a summary of the assemblage. The detailed catalogue of the survey finds follows and is extended by a catalogue of an out-of-context tomb group recovered during the survey. All the illustrations of the ceramics are interactive, forming a graphical interface to the data set. The full database of the ceramics is published

  5. Italy seeks a strategy. (United States)

    Owen, M


    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.

  6. Fatto in Italia: Refashioning Italy

    Directory of Open Access Journals (Sweden)

    Tiziana Ferrero-Regis


    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.

  8. Valley evolution by meandering rivers (United States)

    Limaye, Ajay Brian Sanjay

    Fluvial systems form landscapes and sedimentary deposits with a rich hierarchy of structures that extend from grain- to valley scale. Large-scale pattern formation in fluvial systems is commonly attributed to forcing by external factors, including climate change, tectonic uplift, and sea-level change. Yet over geologic timescales, rivers may also develop large-scale erosional and depositional patterns that do not bear on environmental history. This dissertation uses a combination of numerical modeling and topographic analysis to identify and quantify patterns in river valleys that form as a consequence of river meandering alone, under constant external forcing. Chapter 2 identifies a numerical artifact in existing, grid-based models that represent the co-evolution of river channel migration and bank strength over geologic timescales. A new, vector-based technique for bank-material tracking is shown to improve predictions for the evolution of meander belts, floodplains, sedimentary deposits formed by aggrading channels, and bedrock river valleys, particularly when spatial contrasts in bank strength are strong. Chapters 3 and 4 apply this numerical technique to establishing valley topography formed by a vertically incising, meandering river subject to constant external forcing---which should serve as the null hypothesis for valley evolution. In Chapter 3, this scenario is shown to explain a variety of common bedrock river valley types and smaller-scale features within them---including entrenched channels, long-wavelength, arcuate scars in valley walls, and bedrock-cored river terraces. Chapter 4 describes the age and geometric statistics of river terraces formed by meandering with constant external forcing, and compares them to terraces in natural river valleys. The frequency of intrinsic terrace formation by meandering is shown to reflect a characteristic relief-generation timescale, and terrace length is identified as a key criterion for distinguishing these

  12. The Central Valley Hydrologic Model (United States)

    Faunt, C.; Belitz, K.; Hanson, R. T.


    Historically, California’s Central Valley has been one of the most productive agricultural regions in the world. The Central Valley also is rapidly becoming an important area for California’s expanding urban population. In response to this competition for water, a number of water-related issues have gained prominence: conjunctive use, artificial recharge, hydrologic implications of land-use change, subsidence, and effects of climate variability. To provide information to stakeholders addressing these issues, the USGS made a detailed assessment of the Central Valley aquifer system that includes the present status of water resources and how these resources have changed over time. The principal product of this assessment is a tool, referred to as the Central Valley Hydrologic Model (CVHM), that simulates surface-water flows, groundwater flows, and land subsidence in response to stresses from human uses and from climate variability throughout the entire Central Valley. The CVHM utilizes MODFLOW combined with a new tool called “Farm Process” to simulate groundwater and surface-water flow, irrigated agriculture, land subsidence, and other key processes in the Central Valley on a monthly basis. This model was discretized horizontally into 20,000 1-mi2 cells and vertically into 10 layers ranging in thickness from 50 feet at the land surface to 750 feet at depth. A texture model constructed by using data from more than 8,500 drillers’ logs was used to estimate hydraulic properties. Unmetered pumpage and surface-water deliveries for 21 water-balance regions were simulated with the Farm Process. Model results indicate that human activities, predominately surface-water deliveries and groundwater pumping for irrigated agriculture, have dramatically influenced the hydrology of the Central Valley. These human activities have increased flow though the aquifer system by about a factor of six compared to pre-development conditions. The simulated hydrology reflects spatial

    Bovine viral diarrhea virus (BVDV) type 1 in Italy is characterized by high genetic diversity, with at least 20 subtypes. Subtype 1f is endemic in a restricted geographic area, meaning that it has local distribution. We investigated the population dynamics of BVDV-1f in Northern Italy and characterized the transmission chains of a subset of samples from Piedmont and Aosta Valley regions. A total of 51 samples from 1966 to 2013 were considered and 5' UTR sequences were used for phylogeography. A subset of 12 samples was selected for Npro gene sequencing and further characterization of the transmission chains using both molecular and epidemiological data. Phylogeography estimated the root of BVDV-1f tree in Veneto in 1965. Four significant subclades included sequences clustering by region: Lombardy (n=3), Lombardy and Emilia-Romagna (n=7), Piedmont (n=17), Piedmont and Aosta Valley (n=21). The Piedmont-only subclade has a ladder-like branching structure, while the Piedmont and Aosta Valley subclade has a nearly complete binary structure. In the subset, the outbreak reconstruction identified one sample from Piedmont as the most probable source of infection for the Aosta Valley cases. An ad hoc questionnaire submitted to public veterinarians revealed connections between sampled and non-sampled farms by means of trades, exhibitions and markets. According to the phylogeography, BVDV-1f moved westward, entering from Veneto, and spreading to Lombardy and Emilia-Romagna in the early 1990s, and finally to Piedmont and Aosta Valley in the first decade of 2000s. Both phylogeographic analyses on the whole dataset and on the selection of Npro dataset pointed out that subtype 1f entered Aosta Valley from Piedmont. The integration of molecular and epidemiological data revealed connections between farms, and such approach should be considered in any control plan. In Aosta Valley, the study showed that BVDV1f can be controlled only monitoring the introduction of cattle from Piedmont

    Directory of Open Access Journals (Sweden)

    Skënder Muçaj


    In St. Clement’s bishopric Church Slavonic was used as a liturgical language. For that purpose, a set of Byzantine liturgical books was translated from Greek into Church Slavonic, and Clement took an active part in this process. Liturgical pecularities of these books partially observed in Greek manuscripts of South Italian provenance testify to the hypothesis that Greek sources of the earliest Church Slavonic translations belonged to liturgical tradition of Epirus, similar to those of South Italy. This also proves the location of St. Clement’s bishopric in the valley of the Shushica River.

  15. Usutu Virus Antibodies in Blood Donors and Healthy Forestry Workers in the Lombardy Region, Northern Italy. (United States)

    Percivalle, Elena; Sassera, Davide; Rovida, Francesca; Isernia, Paola; Fabbi, Massimo; Baldanti, Fausto; Marone, Piero


    Usutu virus (USUV), a member of the genus Flavivirus, is known to circulate at low prevalence in Northern Italy, and has been reported to cause overt infection. USUV was first reported in Europe in 2001, but a retrospective study showed that it has been present in Italy at least since 1996. Seroprevalence data for USUV antibodies in sera are being collected in different European countries, showing circulation at low prevalence in human populations. Interestingly, two consecutive studies in Northern Italy indicate a possible increase in the presence of the virus, from 0% to 0.23% seroprevalence in blood donors. In this study, antibodies against USUV were measured in 3 consecutive blood samples collected from October 2014 to December 2015 from 33 forestry workers in the Po river valley, while samples from 200 blood donors from the same geographical area were tested in parallel. Neutralizing and IgG antibodies were found in six forestry workers (18.1%) and in two blood donors (1%). Our results indicate that USUV circulation in the examined area, part of a highly populated region in Northern Italy, is higher than expected. Healthy subjects exhibit a higher prevalence than what was found in a previous report in an adjoining region (0.23%), while the population at risk shows a much higher prevalence value (18.1%).

In this study, we analyze the evolution of vertical profile of black carbon (BC) through tethered balloon observations and chemistry-transport modelling. Black carbon is regarded as the second most important anthropogenic climate forcing agent and its concentration varies significantly depending on the altitude and the sources on the territory. In winter of 2010 University Of Milan Bicocca conducted three intensive measurements campaigns over three Italian basin valleys (Terni, Po Valley, Passiria Valley). The choice of the valleys was made taking into consideration the orography and the river basin structure. The measurement campaign was based on a helium-filled tethered balloon, on which the instrumentation for the analysis has been mounted; the instrumentation consisted on a meteorological station, an OPC, a cascade impactor and a micro-Aethalometer. Subsequently, at University of L'Aquila simulations were produced to help interpretation of these vertical aerosol profiles (mass, composition and distribution) and related optical properties (scattering, absorption) using a chemistry-transport model (WRF-CHIMERE) at high horizontal resolution (1 km). The analysis focused primarily on the calculation of the heating rate and of the Direct Radiative Effect (DRE), and on the analysis of the

    Nanda, Anil; Khan, Imad Saeed; Apuzzo, Michael L


    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.

  20. Mechanically and optically controlled graphene valley filter

    Energy Technology Data Exchange (ETDEWEB)

    Qi, Fenghua; Jin, Guojun, E-mail: [National Laboratory of Solid State Microstructures and Department of Physics, Nanjing University, Nanjing 210093 (China)


    We theoretically investigate the valley-dependent electronic transport through a graphene monolayer modulated simultaneously by a uniform uniaxial strain and linearly polarized light. Within the Floquet formalism, we calculate the transmission probabilities and conductances of the two valleys. It is found that valley polarization can appear only if the two modulations coexist. Under a proper stretching of the sample, the ratio of the light intensity and the light frequency squared is important. If this quantity is small, the electron transport is mainly contributed by the valley-symmetric central band and the conductance is valley unpolarized; but when this quantity is large, the valley-asymmetric sidebands also take part in the transport and the valley polarization of the conductance appears. Furthermore, the degree of the polarization can be tuned by the strain strength, light intensity, and light frequency. It is proposed that the detection of the valley polarization can be realized utilizing the valley beam splitting. Thus, a graphene monolayer can be used as a mechanically and optically controlled valley filter.

  3. Pharmacovigilance in Italy: An overview (United States)

    Mazzitello, Carmela; Esposito, Stefania; De Francesco, Adele E.; Capuano, Annalisa; Russo, Emilio; De Sarro, Giovambattista


    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.

  4. Spin-Valley Beam Splitter in Graphene

    CERN Document Server

    Song, Yu; Shi, Zhi-Gui; Li, Shun; Zhang, Jian


    The fourfold spin-valley degenerate degrees of freedom in bulk graphene can support rich physics and novel applications associated with multicomponent quantum Hall effects and linear conductance filtering. In this work, we study how to break the spin-valley degeneracy of electron beams spatially. We propose a spin-valley beam splitter in a gated ferromagnetic/pristine/strained graphene structure. We demonstrate that, in a full resonant tunneling regime for all spin-valley beam components, the formation of quasi-standing waves can lead four giant lateral Goos-H\\"{a}nchen shifts as large as the transverse beam width, while the interplay of the two modulated regions can lead difference of resonant angles or energies for the four spin-valley flavors, manifesting an effective spin-valley beam splitting effect. The beam splitting effect is found to be controllable by the gating and strain.

  9. Italy: An Open Air Museum (United States)

    Pizzorusso, Ann


    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.

  12. Valley filtering due to orbital magnetic moment in bilayer graphene (United States)

    Park, Chang-Soo


    We investigate the effect of valley-dependent orbital magnetic moment on the transmission of quasiparticles through biased bilayer graphene npn and pnp junctions in the presence of out-of-plane magnetic field. It is shown that the valley-polarized Zeeman-like energy splitting, due to the interaction of orbital magnetic moment with magnetic field, can suppress the transmission of quasiparticles of one valley while transmitting those of the other valley. This valley-selective transmission property can be exploited for valley filtering. We demonstrate that the npn and pnp junction, respectively, filters off the K‧-valley and K-valley particles, with nearly perfect degree of filtration.

We provide new evidence for the formation of heterogeneous beaver meadows on riverine system floodplains and terraces where dynamic flows are capable of breaching in-channel beaver dams. Our data show a 1.7-m high beaver dam triggered overbank flooding that drowned vegetation in areas deeply flooded, deposited nutrient-rich sediment in a spatially heterogeneous pattern on the floodplain and terrace, and scoured soils in other areas. The site quickly de-watered following the dam breach by high stream flows, protecting the deposited sediment from future re-mobilization by overbank floods. Bare sediment either exposed by scouring or deposited by the beaver flood was quickly colonized by a spatially heterogeneous plant community, forming a beaver meadow. Many willow and some aspen seedlings established in the more heavily disturbed areas, suggesting the site may succeed to a willow carr plant community suitable for future beaver re-occupation. We expand existing theory beyond the beaver pond to include terraces within valleys. This more fully explains how beavers can help drive the formation of alluvial valleys and their complex vegetation patterns as was first postulated by Ruedemann and Schoonmaker in 1938. ?? 2010 John Wiley & Sons, Ltd.

  16. Food habits of the stone marten (Martes foina) in the upper Aveto Valley (Northern Apennines, Italy)


    Adriano Martinoli; Damiano Preatoni


    Abstract The diet of the stone marten (Martes foina) was studied analysing 63 faeces collected from February 1990 to December 1991. The results were expressed as relative percentage of frequency (Fr%) and as percentage of mean bulk (Vm%). Mammals, mainly rodents, were the staple in the diet (annual Vm% = 62.9) and reached a maximum peak in winter (Vm% = 79.4). Vegetables were mostly represented by Rosaceae fruits (annual Vm% = 22.3) and were ...

  17. Transforming the "Valley of Death" into a "Valley of Opportunity" (United States)

    Jedlovec, Gary J.; Merceret, Francis J.; O'Brien, T. P.; Roeder, William P.; Huddleston, Lisa L.; Bauman, William H., III


    Transitioning technology from research to operations (23 R2O) is difficult. The problem's importance is exemplified in the literature and in every failed attempt to do so. Although the R2O gap is often called the "valley of death", a recent a Space Weather editorial called it a "Valley of Opportunity". There are significant opportunities for space weather organizations to learn from the terrestrial experience. Dedicated R2O organizations like those of the various NOAA testbeds and collaborative "proving ground" projects take common approaches to improving terrestrial weather forecasting through the early transition of research capabilities into the operational environment. Here we present experience-proven principles for the establishment and operation of similar space weather organizations, public or private. These principles were developed and currently being demonstrated by NASA at the Applied Meteorology Unit (AMU) and the Short-term Prediction Research and Transition (SPoRT) Center. The AMU was established in 1991 jointly by NASA, the U.S. Air Force (USAF) and the National Weather Service (NWS) to provide tools and techniques for improving weather support to the Space Shuttle Program (Madura et al., 2011). The primary customers were the USAF 45th Weather Squadron (45 WS) and the NWS Spaceflight Meteorology Group (SMG who provided the weather observing and forecast support for Shuttle operations). SPoRT was established in 2002 to transition NASA satellite and remote-sensing technology to the NWS. The continuing success of these organizations suggests the common principles guiding them may be valuable for similar endeavors in the space weather arena.

  18. Photosensitive Epilepsy In Kashmir Valley

    Directory of Open Access Journals (Sweden)

    Saleem S M


    Full Text Available A random population of 618 people with epilepsy hailing from different parts of Kashmir valley was screened for photosensitivity both clinically and on a standard protocol of intermittent photic stimulation (IPS provoked EEG recordings. Six (0.9% patients with a mean age of 15+6.57 years were found to be photosensitive; five had generalized and one had absence seizures. The baseline EEG in all patients showed generalized epileptiform discharges. On IPS, similar EEG findings were obtained with a narrow range of stimulus frequency i.e. 7-12 cycles/sec. There appears to be a low prevalence of photo-sensitivity in our epileptic population, possibly related to genetic factors.

  19. CAS Introductory Course in Italy

    CERN Multimedia


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

  20. Via Francigena Mountain Itineraries: the Case of Piacenza Valleys

    Directory of Open Access Journals (Sweden)

    Stefania Cerutti


    Full Text Available Religious tourism has experienced a strong growth in recent years. It represents a complex and articulate phenomenon, in which the reasons and proposals related to the devotional and personal sphere are combined with a series of innovative opportunities that help reach a depth knowledge of a territory. The religious motive often means that pilgrims travel along specific routes to visit a number of shrines or even to complete lengthy itineraries. Increasingly, purely religious motives are becoming mixed with more secular forms of religious tourism, which often centre around specific religious sites. In this perspective, faith itineraries can be interpreted as drivers for territorial development able to evaluate the resources, the peculiarities and the identity of each place. This justifies and motivates the increase of several important initiatives which aim to make a significant contribution to the enhancement of cultural heritage and local development. Many of them are related to the most famous European cultural routes. As regard the Via Francigena, various projects are being hatched, highlighting some ‘minor’ ways of pilgrimage: this is what is currently happening in Piacenza Valleys, in the north of Italy, the case study of the research presented in this paper.

  1. Doppler radar wind field retrieval over the Po Valley

    Directory of Open Access Journals (Sweden)

    Y. K. Goh


    Full Text Available Although methods of using multiple Doppler radars to study wind fields have long been proposed, and many research studies have been made, very few operational radar operators adopt methods which require the use of specific scanning strategies to allow the extraction of wind information. Here we report a collaborative study on dual-Doppler radars based on two Doppler radars in the Po valley, Italy. Unusually, the radars are only about 90 km apart, though operated by the same authority. The wind field syntheses are carried out on a 30 km by 30 km region where the two radars have overlapping scan coverage. An iterative method based on the linear wind model and the equation of mass continuity is used to construct the wind fields. The methodology has been validated by two different methods. The first method is to reconstruct the radial wind observed by each radar, and the second method is calculating and comparing the along-track component with that derived from the observations. Both two comparisons show good agreement with the original data.

  2. Forest types of the "Argentino River Valley" Natural Reserve

    Directory of Open Access Journals (Sweden)

    Bagnato S


    Full Text Available Forest classification is a fundamental target for understanding forest stand dynamics and for sustainable management strategy applications. In this paper the methodological approach of forest types, already used in other Italians region, was applied for the classification of the RNO "Argentino River Valley" (southern Apennine, Italy. This study has been organized in 4 steps: 1 bibliographic analysis and collection of the acquired knowledge; 2 preliminary verification of forest types in the field; 3 description of the different units; 4 final validation of typological units. Using this approach we have characterized 9 categories and 12 forest types units. The description of each units has been filed as cards, where information of different nature is summarized and related to the organization of the typological units, to its location, to the description of the qualitative indicators (disturbances, cohort, mortality, natural dynamic tendencies, SDT, CWD etc. and quantitative indicators (dbh, average height, current annual increment, etc., to the functioning and the current management. For a better understanding of types functioning, "sylvology models" based on the "Spatial Pattern of Relative Collective Interaction" (PSICR and on the principal characteristics influencing and characterizing forest stand dynamics (availability of resources, type and frequency of disturbances, stand development, etc. have been singled out and proposed. The "forest types map" and other maps useful for the management of forest resources have been obtained. Moreover, data collected did allow to formulate several hypotheses on sustainable management.

  3. First national intercomparison of solar ultraviolet radiometers in Italy

    Directory of Open Access Journals (Sweden)

    H. Diémoz


    Full Text Available A blind intercomparison of ground-based ultraviolet (UV instruments has been organized for the first time in Italy. The campaign was coordinated by the Environmental Protection Agency of Aosta Valley (ARPA Valle d'Aosta and took place in Saint-Christophe (45.8° N, 7.4° E, 570 m a.s.l., in the Alpine region, from 8 to 23 June 2010. It involved 8 institutions, 10 broadband radiometers, 2 filter radiometers and 2 spectroradiometers. Synchronized measurements of downward global solar UV irradiance at the ground were collected and the raw series were then individually processed by the respective operators on the base of their own procedures and calibration data. A radiative transfer model was successfully applied as an interpretative tool. The input parameters and output results are described in detail. The comparison was performed in terms of global solar UV Index and integrated UV-A irradiance against a well-calibrated double monochromator spectroradiometer as reference. An improved algorithm for comparing broadband data and spectra has been developed and is discussed in detail. For some instruments, we found average deviations ranging from −16 % up to 20 % relative to the reference and diurnal variations as large as 15 % even in clear days. Remarkable deviations were found for the instruments calibrated in the manufacturers' facilities and never involved in field intercomparison. Finally, some recommendations to the UV operators based on the campaign results are proposed.

  4. Qena Valley Evolution, Eastern Desert, Egypt (United States)

    Abdelkareem, Mohamed


    Remotely sensed topographic and optical data were used to identify tectonic phenomena in Qena Valley. Using digital elevation model, morphotectonic features were identified. Processing and analysis were carried out by the combined use of: (1) digital elevation model, (2) digital drainage network analysis, (3) optical data analysis, and (4) lineament extraction and analysis. Structural information from other sources, such as geological maps, remotely sensed images and field observations were analyzed with geographic information system techniques. The analysis results reveal that the linear features of Qena Valley controlled by several structural elements have different trends NW-SE, NE-SW and N-S trends. Basement rocks at Qena valley has a major NE-SW trending and the sedimentary rocks are dominated by a NW-SE, NE-SW and N-S trends while, E-W are less abundant. The NE-SW trends at north Eastern Desert Egypt attain to normal faults that reflect extension in NW-SE direction, which is related to strike slip faulting along NW-SE directed Najd fault system. Further, the NE-SW is abundant as joints and fractures seem to have controlled the path of the Nile in Qift - Qena area. The NW-SE direction are abundant in the rock fracture trends (Gulf of Suez or Red Sea) and reflects Neoproterozoic faults have been reactivated in Neogene during rifting events of the Red Sea opening and marked the sedimentary rocks at Qena valley. The results of the lineament density map reveals that Qena valley was originated along one fault that trend like the Gulf of Suez and the range of the Red Sea Hills. This major fault was dissected by several lateral faults are seen well exposed at numerous places within the valley, especially on its eastern side. Both sides of Qena valley have a similar density matching may attain to that this lineaments affected Qena valley during rifting. This rifts it probably happened in Early Miocene associated with Red Sea tectonics. The general southward slope of

  6. The Bisagno stream catchment (Genoa, Italy) and its major floods: geomorphic and land use variations in the last three centuries (United States)

    Faccini, Francesco; Paliaga, Guido; Piana, Pietro; Sacchini, Alessandro; Watkins, Charles


    The city of Genoa (Liguria, Italy) and the Bisagno Valley are affected by frequent floods, often with loss of human lives. Historically characterised by high flood hazards, the Bisagno Valley was recently affected by a flood event on 9 October 2014, less than three years after the tragic flood event of 4 November 2011 when six people died, including two children. In the last 50 years, four destructive floods occurred in the Bisagno Valley, in addition to some other events that caused significant damage and economic losses. This paper examines the three largest flood events in terms of intensity and ground effects which affected the Bisagno Valley in the last three centuries: the flood of 25 October 1822, well documented by contemporary sources, the flood of 8 October 1970, undoubtedly the most tragic on record, and the very recent event of 9 October 2014. For this purpose scientific and historical-geographical methodologies were adopted, the latter particularly useful for the reconstruction of the flood event of 1822 and the landscape history of the Bisagno Valley in the nineteenth century. This comparison shows that the Bisagno Valley is characterised by climatic and landform features that have been making the flood events historically common in the area. However, recent climate change and land-use variations, including some major modifications of the catchment basin, have progressively determined a decrease of the concentration time and an increase of runoff, solid transport, and flood hazard. Consequently, in recent decades a growth in the number of flood events occurred, to the extent that the Bisagno today is a famous case study on an international scale.

  7. Discovery of alien water frogs (gen. Pelophylax in Umbria, with first report of P. shqipericus for Italy

    Directory of Open Access Journals (Sweden)

    Dario Domeneghetti


    Full Text Available Allochthonous water frogs (gen. Pelophylax have been repeatedly introduced in several European countries, causing dramatic consequences for the conservation of indigenous taxa. In Italy, invasive populations are known for northern regions, where they were introduced mainly for edible and scientific purposes. Here, we report the first detection of an alien population of water frogs in Central Italy, along the Resina valley (Umbria. Genetic analysis of the mitochondrial ND3 gene polymorphism assigned some specimens to two different Pelophylax ridibundus clades widespread in Central and Eastern Europe. By contrast, two samples matched the mitochondrial DNA (mtDNA sequence of Pelophylax lessonae bergeri, an autochthonous taxon widespread in Central Italy, suggesting possible hybridization between alien and indigenous frogs. Finally, the specific haplotype of Pelophylax shqipericus, the Albanian Pool Frog, was also identified according to mtDNA polymorphism. This record, firstly reported for Italy, poses concerns for the conservation of this cryptic taxon, suggesting that international water frog trade may involve also particularly endangered species.

  15. Detection of valley currents in graphene nanoribbons (United States)

    Chan, K. S.


    There are two valleys in the band structure of graphene zigzag ribbons, which can be used to construct valleytronic devices. We studied the use of a T junction formed by an armchair ribbon and a zigzag ribbon to detect the valley-dependent currents in a zigzag graphene ribbon. A current flowing in a zigzag ribbon is divided by the T junction into the zigzag and armchair leads and this separation process is valley dependent. By measuring the currents in the two outgoing leads, the valley-dependent currents in the incoming lead can be determined. The method does not require superconducting or magnetic elements as in other approaches and thus will be useful in the development of valleytronic devices.

  16. Airborne Dust Models in Valley Fever Research (United States)

    Sprigg, W. A.; Galgiani, J. N.; Vujadinovic, M.; Pejanovic, G.; Vukovic, A. J.; Prasad, A. K.; Djurdjevic, V.; Nickovic, S.


    Dust storms (haboobs) struck Phoenix, Arizona, in 2011 on July 5th and again on July 18th. One potential consequence: an estimated 3,600 new cases of Valley Fever in Maricopa County from the first storm alone. The fungi, Coccidioides immitis, the cause of the respiratory infection, Valley Fever, lives in the dry desert soils of the American southwest and southward through Mexico, Central America and South America. The fungi become part of the dust storm and, a few weeks after inhalation, symptoms of Valley Fever may appear, including pneumonia-like illness, rashes, and severe fatigue. Some fatalities occur. Our airborne dust forecast system predicted the timing and extent of the storm, as it has done with other, often different, dust events. Atmosphere/land surface models can be part of public health services to reduce risk of Valley Fever and exacerbation of other respiratory and cardiovascular illness.

  17. VALMET-A valley air pollution model

    Energy Technology Data Exchange (ETDEWEB)

    Whiteman, C.D.; Allwine, K.J.


    Following a thorough analysis of meteorological data obtained from deep valleys of western Colorado, a modular air-pollution model has been developed to simulate the transport and diffusion of pollutants released from an elevated point source in a well-defined mountain valley during the nighttime and morning transition periods. This initial version of the model, named VALMET, operates on a valley cross section at an arbitrary distance down-valley from a continuous point source. The model has been constructed to include parameterizations of the major physical processes that act to disperse pollution during these time periods. The model has not been fully evaluated. Further testing, evaluations, and development of the model are needed. Priorities for further development and testing are provided.

    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.

  1. Robotic surgery in Italy national survey (2011). (United States)

    Santoro, Eugenio; Pansadoro, Vito


    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.

  2. Multitemporal airborne laser scanning for the analysis of glacier change in South-Tyrol (Italy) (United States)

    Rieg, Lorenzo; Galos, Stephan; Klug, Christoph; Sailer, Rudolf


    The mountain ranges in the area of the Autonomous Province of Bozen - South-Tyrol (Italy) contain numerous glaciers of various sizes and in different elevations and expositions. During the annual melt period, the runoff of these glaciers feeds the Etsch-river, which is the main water source for the extensive fruit production in the Vinschgau, an inner alpine dry valley with very low precipitation. Nevertheless, relatively little is still known about the current state of the glaciers in this area, except from the glacier inventories for 1983, 1997 and 2005/2006 and few glaciers which are subject to mass-balance studies. The study area encompasses the glaciers within the main part of the Ortler-Cevedale group (Sulden and Martell valleys), which is the most heavily glaciated region in South-Tyrol, the glaciers of the upper Ulten valley and the glaciers of the Schnals valley at the alpine main ridge. For this study, two sets of airborne laser scanning (ALS) data are used to calculate the recent changes in glacier area and volume. ALS data from 2005 is available from the Autonomous Province of Bozen, while another data acquisition campaign was conducted in context of the project MALS (Multitemporal Airborne Laserscanning South-Tyrol) in autumn 2011. The extents of all glaciers in the study areas have been delineated for both dates, based on digital terrain models (DTM), hillshades and intensity information. Those results are used to calculate changes in the glaciated areas. The geodetic mass balance for al studied glaciers is calculated as well. Therefore, changes in glacier volume between 2005 and 2011 and their altitudinal distribution are calculated from the differences of the ALS-based DTM. The results of the mass-balance calculations for the single glaciers are interpreted with respect to their spatial distribution, taking topographic parameters such as altitudinal distribution of glacier area, slope into account.

  3. Seismic hazard maps of Italy

    Directory of Open Access Journals (Sweden)

    A. Rebez


    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.

  4. CBRN mobile laboratories in Italy (United States)

    Mari, Giorgio; Giraudi, Giampaolo; Bellino, Mariarosa; Pazienza, Michele; Garibaldi, Claudio; Lancia, Corrado


    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.).

  5. Crustal Deformation In Northeastern Italy. (United States)

    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.

  8. Topological Valley Transport in Two-dimensional Honeycomb Photonic Crystals. (United States)

    Yang, Yuting; Jiang, Hua; Hang, Zhi Hong


    Two-dimensional photonic crystals, in analogy to AB/BA stacking bilayer graphene in electronic system, are studied. Inequivalent valleys in the momentum space for photons can be manipulated by simply engineering diameters of cylinders in a honeycomb lattice. The inequivalent valleys in photonic crystal are selectively excited by a designed optical chiral source and bulk valley polarizations are visualized. Unidirectional valley interface states are proved to exist on a domain wall connecting two photonic crystals with different valley Chern numbers. With the similar optical vortex index, interface states can couple with bulk valley polarizations and thus valley filter and valley coupler can be designed. Our simple dielectric PC scheme can help to exploit the valley degree of freedom for future optical devices.

  9. Foreign children with cancer in Italy

    Directory of Open Access Journals (Sweden)

    Zecca Marco


    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.

  10. Christmas Valley Renewable Energy Assessment

    Del Mar, Robert [Oregon Department of Energy, Salem, OR (United States)


    In partnership with the Oregon Military Department, the Department of Energy used the award to assess and evaluate renewable resources in a 2,622-acre location in Lake County, central Oregon, leading to future development of up to 200 MW of solar electricity. In partnership with the Oregon Military Department, the Department of Energy used the award to assess and evaluate renewable resources in a 2,622-acre location in Lake County, central Oregon, leading to future development of up to 200 MW of solar electricity. The Oregon Military Department (Military) acquired a large parcel of land located in south central Oregon. The land was previously owned by the US Air Force and developed for an Over-the-Horizon Backscatter Radar Transmitter Facility, located about 10 miles east of the town of Christmas Valley. The Military is investigating a number of uses for the site, including Research and Development (R&D) laboratory, emergency response, military operations, developing renewable energy and related educational programs. One of the key potential uses would be for a large scale solar photovoltaic power plant. This is an attractive use because the site has excellent solar exposure; an existing strong electrical interconnection to the power grid; and a secure location at a moderate cost per acre. The project objectives include: 1. Site evaluation 2. Research and Development (R&D) facility analysis 3. Utility interconnection studies and agreements 4. Additional on-site renewable energy resources analysis 5. Community education, outreach and mitigation 6. Renewable energy and emergency readiness training program for veterans

  11. Hydraulic stream network conditioning by a tectonically induced, giant, deep-seated landslide along the front of the Apennine chain (south Italy

    Directory of Open Access Journals (Sweden)

    A. Galeandro


    Full Text Available The tectonic stresses that produced the uplift of Apennine chain ridge in southern Italy generated advanced buried thrusts of allochthonous deposits that induced deformations of foredeep deposits. This thrust may cause giant, deep-seated landslides at the front of the chain. Starting from a specific case history in low Biferno Valley, this work presents how giant, deep-seated landslides along the front of the chain may be generated by the thrust of allochthonous nappe of the chain. In addition, the influence that these huge phenomena may have on landslide and flood susceptibility and on natural hazards of the involved area is analysed. The work presents an interpretation of local morphology and stream network paths of low Biferno Valley as a consequence of a giant, deep-seated landslide affecting the right side of the valley. The proposed interpretation is supported by numerical geomorphological analyses of the area at stake. It is shown how both the morphologies of the catchments of the river Biferno and its tributary Cigno and stream paths are strongly conditioned by this large, deep-seated landslide. This landslide deviates the stream paths affecting both the flooding susceptibility of low Biferno Valley and landslide susceptibility on the left side of Biferno Valley.

  12. Hospitalisation among immigrants in Italy

    Directory of Open Access Journals (Sweden)

    Geraci Salvatore


    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.

  13. Magnetotelluric investigation across the Agri Valley: preliminary results. (United States)

    Balasco, Marianna; Romano, Gerardo; Siniscalchi, Agata; Alfredo Stabile, Tony


    The Agri Valley is an axial zone of the Southern Apennines thrust belt chain with a strong seismogenic potential where two important energy technologies responsible for inducing/triggering seismicity are active: (1) the disposal at the Costa Molina 2 injection well of the wastewater produced during the exploitation of the biggest onshore oil field in west Europe (27 wells producing more than 80,000 barrels of crude oil per day), managed by the Eni S.p.A., and (2) the water loading and unloading operations in the Pertusillo artificial reservoir. It is recognized the possibility that the fluctuation of the water level inside the reservoir, due to the hydrological cycle for example, produces pressure perturbations at the bottom of reservoir, causing induced seismicity. Furthermore it is even more known the role of fluids in the rupture processes which could cause an increase of pore pressure specially at high rate of injection fluids and/or for the presence of weakening of preexisting faults. With the aim to better characterize and understand the physical processes involved in the observed induced/triggered seismicity, in 2016 a broadband seismic network, covering an area of about 20 km x 20 km nearby the Pertusillo Dam and Costa Molina2 well has been installed in the framework of SIR-MIUR project INSIEME (INduced Seismicity in Italy: Estimation, Monitoring, and sEismic risk mitigation) and a MagnetoTelluric (MT) survey has been performed. The MT investigation consists of 25 soundings aligned along 30 km profile oriented at about N40 direction, orthogonal with the strike of the major and noticeable geological structures and crossing both of the source that may induce/trigger seismicity. In this work, we present the preliminary 2D resistivity model which provides useful deep geophysical information for understanding the geological and structural setting of the Agri Valley. Moreover, the comparison of the resistivity model with the earthquake location as inferred from

    Lari, Serena; Frattini, Paolo; Battista Crosta, Giovanni; Agliardi, Federico; Buldrini, Marco; Oliveri, Stefano; Seminati, Paolo; Pozza, Francesco


    The impact of industrial accidents triggered by landslides in the Lombardy Alps (northern Italy) is not negligible, as demonstrated by the event of the refinery Ilsea (Valmadrera, LC), where an explosion caused by a rockfall caused a victim and two injuries in 1981. This work proposes a methodology for the assessment of societal and economic risk connected to industrial accidents triggered by rockfalls in the area of Brescia, northern Italy. The study area is located between Lake Iseo and Lake Garda, and includes lower Valcamonica, lower Valtrompia, and lower Valsabbia. The area has an extension of 1,508 km2 and includes 82 municipalities. 727,000 people live in this area, where valley bottoms are strongly urbanised, and densely populated. The expected frequency of occurrence of rockfalls in the area was calculated by combining the frequency of block detachment and the frequency of transit. The detachment frequency was estimated using intensity-frequency curves, obtained adapting and calibrating existing curves from the literature using historical events of the area (374 events in 20 years). Considering that detachment frequency depends on the size of the block, 7 different scenarios were analysed, each of them characterised by blocks with different volume, from 0.01 m3 to 10,000 m3. The transit frequency was calculated by means of the rockfall 3D model HY-STONE. The model simulates the propagation of three-dimensional trajectories of blocks on complex terrain morphologies described by a DTM. Simulations were performed using a 20 m x 20 m DTM, and considering as source areas all the cells steepest than 40° (323 km2). Ten blocks were launched from each source, with a stochastic approach that accounts for uncertainties about the modelling parameters. Energy restitution and rolling friction coefficients were assigned to different cells according to different lithology and land use, and calibrated using historical events. As a result of the model, kinetic energy of

    Directory of Open Access Journals (Sweden)

    C. Fidani


    Full Text Available A seven-month collection of testimonials about the 6 April 2009 earthquake in Aquila, Abruzzo region, Italy, was compiled into a catalogue of non-seismic phenomena. Luminous phenomena were often reported starting about nine months before the strong shock and continued until about five months after the shock. A summary and list of the characteristics of these sightings was made according to 20th century classifications and a comparison was made with the Galli outcomes. These sightings were distributed over a large area around the city of Aquila, with a major extension to the north, up to 50 km. Various earthquake lights were correlated with several landscape characteristics and the source and dynamic of the earthquake. Some preliminary considerations on the location of the sightings suggest a correlation between electrical discharges and asperities, while flames were mostly seen along the Aterno Valley.

  16. A Reappraisal of the Purported Gastric Pellet with Pterosaurian Bones from the Upper Triassic of Italy.

    Directory of Open Access Journals (Sweden)

    Borja Holgado

    Full Text Available A small accumulation of bones from the Norian (Upper Triassic of the Seazza Brook Valley (Carnic Prealps, Northern Italy was originally (1989 identified as a gastric pellet made of pterosaur skeletal elements. The specimen has been reported in literature as one of the very few cases of gastric ejecta containing pterosaur bones since then. However, the detailed analysis of the bones preserved in the pellet, their study by X-ray microCT, and the comparison with those of basal pterosaurs do not support a referral to the Pterosauria. Comparison with the osteology of a large sample of Middle-Late Triassic reptiles shows some affinity with the protorosaurians, mainly with Langobardisaurus pandolfii that was found in the same formation as the pellet. However, differences with this species suggest that the bones belong to a similar but distinct taxon. The interpretation as a gastric pellet is confirmed.

    Gloria INNOCENTI


    Full Text Available The efficacy of foliage fungicide applications against eyespot of soft wheat cv. Serio was evaluated under natural Oculimacula infection in an experimental area in the Po Valley (Northern Italy. The fungicide treatments prochloraz, prochloraz + propiconazole, and trifloxystrobin + cyproconazole were applied in the years of 2006 through to 2009. Seeds were also treated with a formulated product based on guazatine. All foliage fungicides were applied at the stem extension growth stage (Zadoks growth stage 30‒32, and at the manufacturer recommended rates. All tested treatments reduced the disease severity compared with untreated control. Prochloraz alone and particularly in combination with propiconazole gave the greatest efficacy in reducing eyespot. All treatments increased grain yield in 2006 and 2008. The effects of treatments on some yield parameters were also examined.

    Anna Grochowska


    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.

  6. Advanced seismic imaging of overdeepened alpine valleys (United States)

    Burschil, Thomas; Buness, Hermann; Tanner, David; Gabriel, Gerald; Krawczyk, Charlotte M.


    Major European alpine valleys and basins are densely populated areas with infrastructure of international importance. To protect the environment by, e.g., geohazard assessment or groundwater estimation, understanding of the geological structure of these valleys is essential. The shape and deposits of a valley can clarify its genesis and allows a prediction of behaviour in future glaciations. The term "overdeepened" refers to valleys and basins, in which pressurized melt-water under the glacier erodes the valley below the fluvial level. Most overdeepened valleys or basins were thus refilled during the ice melt or remain in the form of lakes. The ICDP-project Drilling Overdeepened Alpine Valleys (DOVE) intends to correlate the sedimentary succession from boreholes between valleys in the entire alpine range. Hereby, seismic exploration is essential to predict the most promising well path and drilling site. In a first step, this DFG-funded project investigates the benefit of multi-component techniques for seismic imaging. At two test sites, the Tannwald Basin and the Lienz Basin, the Leibniz Institute for Applied Geophysics acquired P-wave reflection profiles to gain structural and facies information. Built on the P-wave information, several S-wave reflection profiles were acquired in the pure SH-wave domain as well as 6-C reflection profiles using a horizontal S-wave source in inline and crossline excitation and 3-C receivers. Five P-wave sections reveal the structure of the Tannwald Basin, which is a distal branch basin of the Rhine Glacier. Strong reflections mark the base of the basin, which has a maximum depth of 240 metres. Internal structures and facies vary strongly and spatially, but allow a seismic facies characterization. We distinguish lacustrine, glacio-fluvial, and deltaic deposits, which make up the fill of the Tannwald Basin. Elements of the SH-wave and 6-C seismic imaging correlate with major structures in the P-wave image, but vary in detail. Based on

    ICF Kaiser


    Southern California's Coachella Valley became a Clean Cities region in 1996. Since then, they've made great strides. SunLine Transit, the regional public transit provider, was the first transit provider to replace its entire fleet with compressed natural gas buses. They've also built the foundation for a nationally recognized model in the clean air movement, by partnering with Southern California Gas Company to install a refueling station and developing a curriculum for AFV maintenance with the College of the Desert. Today the valley is home to more than 275 AFVs and 15 refueling stations.

  8. Molecular Epidemiology of Rift Valley Fever Virus (United States)

    Grobbelaar, Antoinette A.; Weyer, Jacqueline; Leman, Patricia A.; Kemp, Alan; Paweska, Janusz T.


    Phylogenetic relationships were examined for 198 Rift Valley fever virus isolates and 5 derived strains obtained from various sources in Saudi Arabia and 16 countries in Africa during a 67-year period (1944–2010). A maximum-likelihood tree prepared with sequence data for a 490-nt section of the Gn glycoprotein gene showed that 95 unique sequences sorted into 15 lineages. A 2010 isolate from a patient in South Africa potentially exposed to co-infection with live animal vaccine and wild virus was a reassortant. The potential influence of large-scale use of live animal vaccine on evolution of Rift Valley fever virus is discussed. PMID:22172568

  10. The Alto Tiberina Near Fault Observatory (northern Apennines, Italy

    Directory of Open Access Journals (Sweden)

    Lauro Chiaraluce


    Full Text Available The availability of multidisciplinary and high-resolution data is a fundamental requirement to understand the physics of earthquakes and faulting. We present the Alto Tiberina Near Fault Observatory (TABOO, a research infrastructure devoted to studying preparatory processes, slow and fast deformation along a fault system located in the upper Tiber Valley (northern Apennines, dominated by a 60 km long low-angle normal fault (Alto Tiberina, ATF active since the Quaternary. TABOO consists of 50 permanent seismic stations covering an area of 120 × 120 km2. The surface seismic stations are equipped with 3-components seismometers, one third of them hosting accelerometers. We instrumented three shallow (250 m boreholes with seismometers, creating a 3-dimensional antenna for studying micro-earthquakes sources (detection threshold is ML 0.5 and detecting transient signals. 24 of these sites are equipped with continuous geodetic GPS, forming two transects across the fault system. Geochemical and electromagnetic stations have been also deployed in the study area. In 36 months TABOO recorded 19,422 events with ML ≤ 3.8 corresponding to 23.36e-04 events per day per squared kilometres; one of the highest seismicity rate value observed in Italy. Seismicity distribution images the geometry of the ATF and its antithetic/synthetic structures located in the hanging-wall. TABOO can allow us to understand the seismogenic potential of the ATF and therefore contribute to the seismic hazard assessment of the area. The collected information on the geometry and deformation style of the fault will be used to elaborate ground shaking scenarios adopting diverse slip distributions and rupture directivity models.

  11. Tracer Tests History in the Alburni Massif (Southern Italy) (United States)

    Parise, Mario; Santo, Antonio


    The Alburni Massif (Campania, southern Italy) is among the most important Italian karst areas, due to high number of caves (about 300), with several karst systems reaching depth of 500 m, and development of some kilometres. This remarkable karst is mainly related to three geological factors: presence of highly karstifiable and low-fractured Cretaceous and Tertiary limestones; peculiar morphological and structural conformation, with four main faults bounding the massif, forming a wide highplain with a variety of infiltration sites; presence of blind valleys and small catchments on flysch deposits, feeding the many swallets at the contact with the limestone rocks. The Alburni Massif represents an important hydrogeological structure, with a potential of about 10 mc/sec. Three basal spring systems are the main outcomes (Castelcivita, Tanagro and Pertosa) while other minor systems are located at higher elevation, as the Auso spring. The Castelcivita and Pertosa caves, located on the Alburni SW and NE foothills, respectively, are of particular importance also for the local economy, since Castelcivita became a show cave in 1930, followed two years later by Pertosa. Since 1950 many cavers have explored the Alburni Massif, due to the high potential of overall karstification, estimated in about 1 300m, and to the presence on its southern slope of the spectacular Auso spring. In this paper, the tracer tests carried out in the Massif are summarized, with the aim to update the available hydrogeological data, with particular regard to the most recent explorations and tests, carried out during the last 5 years, which brought significant new data to the overall knowledge of this remarkable karst area.

  12. [Inequalities in health in Italy]. (United States)

    Caiazzo, Antonio; Cardano, Mario; Cois, Ester; Costa, Giuseppe; Marinacci, Chiara; Spadea, Teresa; Vannoni, Francesca; Venturini, Lorenzo


    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

  19. The optical properties and chemical composition of Po Valley fog water (United States)

    Jahl, L.; Hawkins, L. N.; Gilardoni, S.


    The chemical composition and solar radiation absorption properties of fog water are important because of the effects these properties can have on the climate. Fog samples contain compounds that may absorb light, and this radiative forcing may be significant. The Po Valley, located between the Apennine and Alps mountain ranges in Italy, has a high occurrence of fog events, which can be up to 30% of the time in the winter season. Absorption spectra of fog water samples from San Pietro Capofiume, Italy were taken in a Liquid Waveguide Capillary Cell with a UV-visible spectrophotometer. Spectra were fitted and absorptions at different wavelengths were correlated to the organic carbon and organic nitrogen concentrations of the samples. Ion chromatography was also used to obtain the concentrations of several ions such as nitrite, nitrate, sulfate, acetate, ammonium, and various amines. A correlation was found between absorbance and organic carbon content, as well as between absorbance at less than 300 nm wavelengths and organic nitrogen content. Characteristic absorptivities at 365 nm were calculated from Beer's law with regard to the organic carbon content and revealed similar results to those calculated from Los Angeles fog water samples earlier this year. The absorption angstrom exponents of the samples imply that the likely source of the optically active species is from biomass burning, and this will later be confirmed by a tracer analysis. High organic nitrogen : organic carbon ratios in all samples suggest that compounds containing nitrogen have a large contribution to the light absorbing properties of fog water.

  20. Observation of acoustic valley vortex states and valley-chirality locked beam splitting (United States)

    Ye, Liping; Qiu, Chunyin; Lu, Jiuyang; Wen, Xinhua; Shen, Yuanyuan; Ke, Manzhu; Zhang, Fan; Liu, Zhengyou


    We report an experimental observation of the classical version of valley polarized states in a two-dimensional hexagonal sonic crystal. The acoustic valley states, which carry specific linear momenta and orbital angular momenta, were selectively excited by external Gaussian beams and conveniently confirmed by the pressure distribution outside the crystal, according to the criterion of momentum conservation. The vortex nature of such intriguing bulk crystal states was directly characterized by scanning the phase profile inside the crystal. In addition, we observed a peculiar beam-splitting phenomenon, in which the separated beams are constructed by different valleys and locked to the opposite vortex chirality.

  12. Pumpernickel Valley Geothermal Project Thermal Gradient Wells

    Energy Technology Data Exchange (ETDEWEB)

    Z. Adam Szybinski


    The Pumpernickel Valley geothermal project area is located near the eastern edge of the Sonoma Range and is positioned within the structurally complex Winnemucca fold and thrust belt of north-central Nevada. A series of approximately north-northeast-striking faults related to the Basin and Range tectonics are superimposed on the earlier structures within the project area, and are responsible for the final overall geometry and distribution of the pre-existing structural features on the property. Two of these faults, the Pumpernickel Valley fault and Edna Mountain fault, are range-bounding and display numerous characteristics typical of strike-slip fault systems. These characteristics, when combined with geophysical data from Shore (2005), indicate the presence of a pull-apart basin, formed within the releasing bend of the Pumpernickel Valley – Edna Mountain fault system. A substantial body of evidence exists, in the form of available geothermal, geological and geophysical information, to suggest that the property and the pull-apart basin host a structurally controlled, extensive geothermal field. The most evident manifestations of the geothermal activity in the valley are two areas with hot springs, seepages, and wet ground/vegetation anomalies near the Pumpernickel Valley fault, which indicate that the fault focuses the fluid up-flow. There has not been any geothermal production from the Pumpernickel Valley area, but it was the focus of a limited exploration effort by Magma Power Company. In 1974, the company drilled one exploration/temperature gradient borehole east of the Pumpernickel Valley fault and recorded a thermal gradient of 160oC/km. The 1982 temperature data from five unrelated mineral exploration holes to the north of the Magma well indicated geothermal gradients in a range from 66 to 249oC/km for wells west of the fault, and ~283oC/km in a well next to the fault. In 2005, Nevada Geothermal Power Company drilled four geothermal gradient wells, PVTG-1

  16. Postgraduate Courses in Pharmaceutical Medicine in Italy

    Directory of Open Access Journals (Sweden)

    Domenico Criscuolo


    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.

  5. The 1963 Vajont landslide (Italy) simulated through a numerical 2D code (United States)

    Zaniboni, Filippo; Ausilia Paparo, Maria; Elsen, Katharina; Tinti, Stefano


    On October 9th, 1963, a huge mass of about 260 million m3 collapsed along Mt. Toc flank into the artificial lake called Vajont and generated a gigantic wave that invested the town of Longarone (North-East Italy, about 100 km north of Venice), provoking about 2000 casualties. The event started a public debate on the responsibilities for the disaster, and also raised crucial issues for the scientific and engineering community, regarding reservoir flank instability and safety of the hydroelectric plant. The peculiar features of the event were immediately evident. The clay layers remained uncovered in the upper part of the detachment niche, supporting the hypothesis of a well-defined pre-existing sliding surface, that could explain the high falling velocity (around 20 m/s as a maximum) and the compactness of the deposit layers that were found to sit almost unperturbed on the bottom of the valley. The numerical study presented here contributes to the understanding of dynamics of the Vajont landslide. It is found that the accurate knowledge of the pre- and post-slide morphology provides tight constraints on the parameters of the numerical model, that are tuned to fit the observed deposit. Numerical simulations are carried out by means of the in-house built code UBO-BLOCK2. The initial sliding body is divided into a mesh of interacting volume-conserving blocks, whose motion is computed numerically. The friction coefficient at the base of the landslide is determined through a best fit search by maximizing the degree of overlapping between the calculated and observed deposits. Our best solution is also able to account for the observed slight easterly rotation of the mass, the different behaviors of the eastern and western part of the sliding surface and the retrogressive motion of the slide that after climbing up the opposite flank of the valley reverted velocity to settle down on the bottom of the valley.

  6. A valley-filtering switch based on strained graphene. (United States)

    Zhai, Feng; Ma, Yanling; Zhang, Ying-Tao


    We investigate valley-dependent transport through a graphene sheet modulated by both the substrate strain and the fringe field of two parallel ferromagnetic metal (FM) stripes. When the magnetizations of the two FM stripes are switched from the parallel to the antiparallel alignment, the total conductance, valley polarization and valley conductance excess change greatly over a wide range of Fermi energy, which results from the dependence of the valley-related transmission suppression on the polarity configuration of inhomogeneous magnetic fields. Thus the proposed structure exhibits the significant features of a valley-filtering switch and a magnetoresistance device.

  7. Groundwater quality in the Owens Valley, California (United States)

    Dawson, Barbara J. Milby; Belitz, Kenneth


    Groundwater provides more than 40 percent of California’s drinking water. To protect this vital resource, the State of California created the Groundwater Ambient Monitoring and Assessment (GAMA) Program. The Priority Basin Project of the GAMA Program provides a comprehensive assessment of the State’s groundwater quality and increases public access to groundwater-quality information. Owens Valley is one of the study areas being evaluated. The Owens study area is approximately 1,030 square miles (2,668 square kilometers) and includes the Owens Valley groundwater basin (California Department of Water Resources, 2003). Owens Valley has a semiarid to arid climate, with average annual rainfall of about 6 inches (15 centimeters). The study area has internal drainage, with runoff primarily from the Sierra Nevada draining east to the Owens River, which flows south to Owens Lake dry lakebed at the southern end of the valley. Beginning in the early 1900s, the City of Los Angeles began diverting the flow of the Owens River to the Los Angeles Aqueduct, resulting in the evaporation of Owens Lake and the formation of the current Owens Lake dry lakebed. Land use in the study area is approximately 94 percent (%) natural, 5% agricultural, and 1% urban. The primary natural land cover is shrubland. The largest urban area is the city of Bishop (2010 population of 4,000). Groundwater in this basin is used for public and domestic water supply and for irrigation. The main water-bearing units are gravel, sand, silt, and clay derived from surrounding mountains. Recharge to the groundwater system is primarily runoff from the Sierra Nevada, and by direct infiltration of irrigation. The primary sources of discharge are pumping wells, evapotranspiration, and underflow to the Owens Lake dry lakebed. The primary aquifers in Owens Valley are defined as those parts of the aquifers corresponding to the perforated intervals of wells listed in the California Department of Public Health database

  8. Estimation of daily PM10concentrations in Italy (2006-2012) using finely resolved satellite data, land use variables and meteorology. (United States)

    Stafoggia, Massimo; Schwartz, Joel; Badaloni, Chiara; Bellander, Tom; Alessandrini, Ester; Cattani, Giorgio; De' Donato, Francesca; Gaeta, Alessandra; Leone, Gianluca; Lyapustin, Alexei; Sorek-Hamer, Meytar; de Hoogh, Kees; Di, Qian; Forastiere, Francesco; Kloog, Itai


    Health effects of air pollution, especially particulate matter (PM), have been widely investigated. However, most of the studies rely on few monitors located in urban areas for short-term assessments, or land use/dispersion modelling for long-term evaluations, again mostly in cities. Recently, the availability of finely resolved satellite data provides an opportunity to estimate daily concentrations of air pollutants over wide spatio-temporal domains. Italy lacks a robust and validated high resolution spatio-temporally resolved model of particulate matter. The complex topography and the air mixture from both natural and anthropogenic sources are great challenges difficult to be addressed. We combined finely resolved data on Aerosol Optical Depth (AOD) from the Multi-Angle Implementation of Atmospheric Correction (MAIAC) algorithm, ground-level PM 10 measurements, land-use variables and meteorological parameters into a four-stage mixed model framework to derive estimates of daily PM 10 concentrations at 1-km2 grid over Italy, for the years 2006-2012. We checked performance of our models by applying 10-fold cross-validation (CV) for each year. Our models displayed good fitting, with mean CV-R2=0.65 and little bias (average slope of predicted VS observed PM 10 =0.99). Out-of-sample predictions were more accurate in Northern Italy (Po valley) and large conurbations (e.g. Rome), for background monitoring stations, and in the winter season. Resulting concentration maps showed highest average PM 10 levels in specific areas (Po river valley, main industrial and metropolitan areas) with decreasing trends over time. Our daily predictions of PM 10 concentrations across the whole Italy will allow, for the first time, estimation of long-term and short-term effects of air pollution nationwide, even in areas lacking monitoring data.

    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.

    To study the prevalence of congenital syphilis and its risk factors in Italy. Prospective study from 1 July 2006 to 30 June 2007. 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.

  13. Pricing and reimbursement of pharmaceuticals in Italy. (United States)

    Folino-Gallo, Pietro; Montilla, Simona; Bruzzone, Mario; Martini, Nello


    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.

  18. Tetanus immunity in construction workers in Italy. (United States)

    Rapisarda, V; Bracci, M; Nunnari, G; Ferrante, M; Ledda, C


    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.

  19. Italy's Economic Performance 1945-92


    Rossi, Nicola; Toniolo, Gianni


    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...

  20. Alternative energy. Southern Italy. Alternativ energi. Syditalien

    Energy Technology Data Exchange (ETDEWEB)


    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.

  3. Culture and the environment in Italy (United States)

    Alexander, David


    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.

  4. [Consistency and dynamics of immigration in Italy]. (United States)

    Blangiardo, G C; Terzera, L


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

  5. Organization of paediatric diabetes units in Italy. (United States)

    La Loggia, Alfonso


    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.

  6. The Marocche rock avalanches (Trentino, Italy) (United States)

    Ivy-Ochs, Susan; Martin, Silvana; Campedel, Paolo; Viganò, Alfio; Alberti, Silvio; Rigo, Manuel; Vockenhuber, Christof


    The floors of the Adige and Sarca River valleys are punctuated by numerous rock avalanche deposits of undetermined age. With a view to understanding predisposition and triggering factors, thus ultimately paleoseismicity in the region, we are studying the geomorphology and timing of the largest rock avalanches of the River Sarca-Lake Garda area (e.g., Marocche, Monte Spinale, Lago di Tovel, Lago di Molveno, San Giovanni and Torbole). Among the most extensive of these deposits, with an area of 13 km2 and a volume of about 109 m3, are the Marocche. Marocche deposits cover the lower Sarca valley north of Lake Garda for a length of more than 8 km with 200 m of debris. Both collapse and bedding parallel sliding are a consequence of dip slopes and the extreme relief on the right side of the valley of nearly 2000 m from the bedrock below the valley floor to the peaks combined with the zones of structural weakness. The rock avalanches developed within carbonate rocks of Mesozoic age, mainly limestones of the Jurassic Calcari Grigi Group. The main scarps are located on the western side of the lower Sarca Valley, along the steep faces of Mt. Brento and Mt. Casale. The presence of these scarps is strictly related to the Southern Giudicarie and the Ballino fault systems. The former is here constituted by regular NNE-directed ESE-vergent thrust faults. The latter has been reactivated as normal faults. These complicated structural relationships favored complex failure mechanisms, including rock slide and massive collapse. At the Marocche itself, based on field relationships and analysis of lidar imagery, we differentiated two large rock avalanches: the Marocca di Kas in the south which overlies and in part buries the Marocche (s.s.) in the northern sector. Previous mapping had suggested up to five rock avalanches in the area where we differentiate two. In spite of hypotheses suggesting failure of the rock avalanches onto stagnating late Pleistocene glaciers, preliminary 36Cl

  7. The nuclear in Italy - state of the art; Le nucleaire en Italie - etat des lieux

    Energy Technology Data Exchange (ETDEWEB)

    Schifano, F.; Ziller, T


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

  8. Optical manipulation of valley pseduospin in 2D semiconductors (United States)

    Ye, Ziliang

    Valley polarization associated with the occupancy in the energy degenerate but quantum mechanically distinct valleys in the momentum space closely resembles spin polarization and has been proposed as a pseudospin carrier for future quantum information technologies. Monolayers of transition metal dichalcogenide (TMDC) crystals, with broken inversion symmetry and large spin-orbital coupling, support robust valley polarization and therefore provide an important platform for studying valley-dependent physics. Besides optical excitation and photoluminescence detection, valley polarization has been electrically measured through the valley Hall effect and created through spin injection from ferromagnetic semiconductor contacts. Moreover, the energy degeneracy of the valley degree of freedom has been lifted by the optical Stark effect. Recently, we have demonstrated optical manipulation of valley coherence, i.e., of the valley pseudospin, by the optical Stark effect in monolayer WSe2. Using below-bandgap circularly polarized light, we rotated the valley pseudospin on the femtosecond time scale. Both the direction and speed of the rotation can be optically controlled by tuning the dynamic phase of excitons in opposite valleys. The pseudospin rotation was identified by changes in the polarization of the photoluminescence. In addition, by varying the time delay between the excitation and control pulses, we directly probed the lifetime of the intervalley coherence. Similar rotation levels have also been observed in static magneto-optic experiments. Our work presents an important step towards the full control of the valley degree of freedom in 2D semiconductors. The work was done in collaboration with Dr. Dezheng Sun and Prof. Tony F. Heinz.

  11. Spatially resolving valley quantum interference of a donor in silicon. (United States)

    Salfi, J; Mol, J A; Rahman, R; Klimeck, G; Simmons, M Y; Hollenberg, L C L; Rogge, S


    Electron and nuclear spins of donor ensembles in isotopically pure silicon experience a vacuum-like environment, giving them extraordinary coherence. However, in contrast to a real vacuum, electrons in silicon occupy quantum superpositions of valleys in momentum space. Addressable single-qubit and two-qubit operations in silicon require that qubits are placed near interfaces, modifying the valley degrees of freedom associated with these quantum superpositions and strongly influencing qubit relaxation and exchange processes. Yet to date, spectroscopic measurements have only probed wavefunctions indirectly, preventing direct experimental access to valley population, donor position and environment. Here we directly probe the probability density of single quantum states of individual subsurface donors, in real space and reciprocal space, using scanning tunnelling spectroscopy. We directly observe quantum mechanical valley interference patterns associated with linear superpositions of valleys in the donor ground state. The valley population is found to be within 5% of a bulk donor when 2.85 ± 0.45 nm from the interface, indicating that valley-perturbation-induced enhancement of spin relaxation will be negligible for depths greater than 3 nm. The observed valley interference will render two-qubit exchange gates sensitive to atomic-scale variations in positions of subsurface donors. Moreover, these results will also be of interest for emerging schemes proposing to encode information directly in valley polarization.

  12. Disorder-dependent valley properties in monolayer WSe2

    KAUST Repository

    Tran, Kha


    We investigate the effect of disorder on exciton valley polarization and valley coherence in monolayer WSe2. By analyzing the polarization properties of photoluminescence, the valley coherence (VC) and valley polarization (VP) are quantified across the inhomogeneously broadened exciton resonance. We find that disorder plays a critical role in the exciton VC, while affecting VP less. For different monolayer samples with disorder characterized by their Stokes shift (SS), VC decreases in samples with higher SS while VP does not follow a simple trend. These two methods consistently demonstrate that VC as defined by the degree of linearly polarized photoluminescence is more sensitive to disorder, motivating further theoretical studies.

  13. Subsurface stratigraphy of the eastern Hollister Valley, California (United States)

    McMasters, Catherine R.; Herd, Darrell G.; Throckmorton, Constance K.; Heusser, Linda E.


    In September 1977, four cores were recovered by shallow auger drilling from Hollister Valley, California, near the Calaveras fault. The wells were drilled to search for evidence that Hollister Valley may have been occupied by a large lake during the late Pleistocene or Holocene. This small valley, near Monterey Bay, may have been dammed by a large landslide on the San Andreas fault (Jenkins, 1973; Herd and Helley, 1977). The cores sampled the first 38 m of sediment below the valley floor, but no lacustrine deposits were found at these sites; a very detailed record to Holocene alluviation in a tectonically subsiding basin. 

  14. Microwave radiometric measurements of soil moisture in Italy

    Directory of Open Access Journals (Sweden)

    G. Macelloni


    Full Text Available Within the framework of the MAP and RAPHAEL projects, airborne experimental campaigns were carried out by the IFAC group in 1999 and 2000, using a multifrequency microwave radiometer at L, C and X bands (1.4, 6.8 and 10 GHz. The aim of the experiments was to collect soil moisture and vegetation biomass information on agricultural areas to give reliable inputs to the hydrological models. It is well known that microwave emission from soil, mainly at L-band (1.4 GHz, is very well correlated to its moisture content. Two experimental areas in Italy were selected for this project: one was the Toce Valley, Domodossola, in 1999, and the other, the agricultural area of Cerbaia, close to Florence, where flights were performed in 2000. Measurements were carried out on bare soils, corn and wheat fields in different growth stages and on meadows. Ground data of soil moisture (SMC were collected by other research teams involved in the experiments. From the analysis of the data sets, it has been confirmed that L-band is well related to the SMC of a rather deep soil layer, whereas C-band is sensitive to the surface SMC and is more affected by the presence of surface roughness and vegetation, especially at high incidence angles. An algorithm for the retrieval of soil moisture, based on the sensitivity to moisture of the brightness temperature at C-band, has been tested using the collected data set. The results of the algorithm, which is able to correct for the effect of vegetation by means of the polarisation index at X-band, have been compared with soil moisture data measured on the ground. Finally, the sensitivity of emission at different frequencies to the soil moisture profile was investigated. Experimental data sets were interpreted by using the Integral Equation Model (IEM and the outputs of the model were used to train an artificial neural network to reproduce the soil moisture content at different depths.

  16. Surface slip during large Owens Valley earthquakes

    KAUST Repository

    Haddon, E. K.


    The 1872 Owens Valley earthquake is the third largest known historical earthquake in California. Relatively sparse field data and a complex rupture trace, however, inhibited attempts to fully resolve the slip distribution and reconcile the total moment release. We present a new, comprehensive record of surface slip based on lidar and field investigation, documenting 162 new measurements of laterally and vertically displaced landforms for 1872 and prehistoric Owens Valley earthquakes. Our lidar analysis uses a newly developed analytical tool to measure fault slip based on cross-correlation of sublinear topographic features and to produce a uniquely shaped probability density function (PDF) for each measurement. Stacking PDFs along strike to form cumulative offset probability distribution plots (COPDs) highlights common values corresponding to single and multiple-event displacements. Lateral offsets for 1872 vary systematically from approximate to 1.0 to 6.0 m and average 3.31.1 m (2 sigma). Vertical offsets are predominantly east-down between approximate to 0.1 and 2.4 m, with a mean of 0.80.5 m. The average lateral-to-vertical ratio compiled at specific sites is approximate to 6:1. Summing displacements across subparallel, overlapping rupture traces implies a maximum of 7-11 m and net average of 4.41.5 m, corresponding to a geologic M-w approximate to 7.5 for the 1872 event. We attribute progressively higher-offset lateral COPD peaks at 7.12.0 m, 12.8 +/- 1.5 m, and 16.6 +/- 1.4 m to three earlier large surface ruptures. Evaluating cumulative displacements in context with previously dated landforms in Owens Valley suggests relatively modest rates of fault slip, averaging between approximate to 0.6 and 1.6 mm/yr (1 sigma) over the late Quaternary.

  17. Anthrax phylogenetic structure in Northern Italy

    Directory of Open Access Journals (Sweden)

    Corrò Michela


    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.

  19. Radioactivity in honey of the central Italy. (United States)

    Meli, Maria Assunta; Desideri, Donatella; Roselli, Carla; Feduzi, Laura; Benedetti, Claudio


    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.

    Full Text Available The suburban area of Bologna city in southeast portion of Po Valley (Northern Italy is characterized by high emission from industrial, urban, agriculture and traffic sources. The presence of an urban waste incinerator get inhabitants to require answers about impact of its emissions on the environmental quality related to human health. The concentrations of some pollutants (Ba, Cd, Co, Cr, Cu, Ni, Pb, V and Zn were determined in topsoil, plants and mosses tissues sampled in sites selected according to different falling out conditions, due to the incinerator and other sources of atmospheric emissions that affect the monitoring area. No correlation was found between metal content and the distance of the incinerator plant. The pollution load index (PLI calculated for soil and moss indicated a low environmental pollution, while highest values in sites downwind of incinerator and in craft area indicate a moderate pollution.

  1. Fertility pattern and family structure in three Alpine settlements in South Tyrol (italy): marriage cohorts from 1750 to 1949. (United States)

    Gögele, Martin; Pattaro, Cristian; Fuchsberger, Christian; Pramstaller, Peter Paul


    Stelvio, Martello and Curon, three villages of the Venosta Valley, South Tyrol (Italy), were recently included in a large genetic survey because of their isolation. This study focuses on the long-term reproductive behaviour of these villages. Family size, age at marriage and marital fertility were estimated based on a genealogy going back in the 17th century. Marriage behaviour was characterized by an elevated age at marriage and a large proportion of adults never getting married. Marital fertility was among the highest worldwide, because couples tried to use the short time at their disposal to have the largest possible number of children. Together with the already known null population expansion and high geographic endogamy rates, the reduced number of siblings who had the opportunity to get married could have favoured an increased genetic homogeneity.

  2. Volume of Valley Networks on Mars and Its Hydrologic Implications (United States)

    Luo, W.; Cang, X.; Howard, A. D.; Heo, J.


    Valley networks on Mars are river-like features that offer the best evidence for water activities in its geologic past. Previous studies have extracted valley network lines automatically from digital elevation model (DEM) data and manually from remotely sensed images. The volume of material removed by valley networks is an important parameter that could help us infer the amount of water needed to carve the valleys. A progressive black top hat (PBTH) transformation algorithm has been adapted from image processing to extract valley volume and successfully applied to simulated landform and Ma'adim Valles, Mars. However, the volume of valley network excavation on Mars has not been estimated on a global scale. In this study, the PBTH method was applied to the whole Mars to estimate this important parameter. The process was automated with Python in ArcGIS. Polygons delineating the valley associated depressions were generated by using a multi-flow direction growth method, which started with selected high point seeds on a depth grid (essentially an inverted valley) created by PBTH transformation and grew outward following multi-flow direction on the depth grid. Two published versions of valley network lines were integrated to automatically select depression polygons that represent the valleys. Some crater depressions that are connected with valleys and thus selected in the previous step were removed by using information from a crater database. Because of large distortion associated with global dataset in projected maps, the volume of each cell within a valley was calculated using the depth of the cell multiplied by the spherical area of the cell. The volumes of all the valley cells were then summed to produce the estimate of global valley excavation volume. Our initial result of this estimate was ~2.4×1014 m3. Assuming a sediment density of 2900 kg/m3, a porosity of 0.35, and a sediment load of 1.5 kg/m3, the global volume of water needed to carve the valleys was

  3. Knickpoints and Hanging Valleys of Licus Vallis, Mars (United States)

    Goudge, T. A.; Fassett, C.


    Licus Vallis is a 350 km long valley system located along the dichotomy boundary on Mars. The main trunk of the valley is incised 200-700 m into the surrounding terrain. The valley heads at an outlet breach of a shallow, 30 km diameter impact crater, and is also fed by a system of tributaries incised into the plateau surrounding Licus Vallis. Many of the tributary valleys, as well as the main stem of the valley fed by the paleolake outlet, have profiles that are not smoothly graded, but rather have distinct reaches with concave downward topography. These sections are either knickpoints or hanging valleys that develop in response to changes in the effective local base level, changes in climate conditions during incision of the valley, or lithologic boundaries in the substrate. Here we present remote sensing observations from images and topography to test these competing hypotheses and further characterize the evolution of this large valley system. Slope-watershed area relationships for the tributaries and main trunk valley are used to distinguish between knickpoints and hanging valleys. Analysis of orbital images does not reveal any distinct layer above which knickpoints develop, and the elevation of knickpoints show no systematic trends that might be expected of a regional lithologic unit(s). Our preliminary results suggest that the distance of knickpoint retreat is correlated with the position of the tributary valley and not the watershed area. Downstream valleys have retreated the most, suggesting they have had the most time to adjust to lowering of the local base level associated with incision of the main valley. These results are most consistent with a wave of incision sweeping up the valley system as it adjusts to a low base level in the northern plains. This conclusion is also consistent with observations of the incision depth of Licus Vallis, which increases approximately linearly downstream. Understanding this signature of base level control on the incision

    Advances in technology have enabled animators and video game designers to design increasingly realistic, human-like characters in animation and games. Although it was intended that this increased realism would allow viewers to appreciate the emotional state of characters, research has shown that audiences often have a negative reaction as the human likeness of a character increases. This phenomenon, known as the Uncanny Valley, has become a benchmark for measuring if a character is believably realistic and authentically human like. This book is an essential guide on how to overcome the Uncanny

  9. Urinary capillariosis in six dogs from Italy

    Directory of Open Access Journals (Sweden)

    A. Mariacher


    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.

  17. Occurrence of Toxoplasma gondii in Carcasses of Pigs Reared in Intensive Systems in Northern Italy. (United States)

    Papini, Roberto; di Ciccio, Pierluigi; Marangi, Marianna; Ghidini, Sergio; Zanardi, Emanuela; Vergara, Alberto; Giangaspero, Annunziata; Nardoni, Simona; Rocchigiani, Guido; Mancianti, Francesca; Ianieri, Adriana


    To evaluate the occurrence of Toxoplasma gondii and to genetically characterize its isolates in carcasses of industrial fattening pigs, blood, diaphragm, and heart samples were collected from 375 carcasses of pigs slaughtered to be processed for Parma ham production. Pigs had been bred on approved farms (n = 75) located in the so-called Food Valley in Italy. Sera were examined for immunoglobulin G antibodies to T. gondii by modified agglutination test (MAT). Both heart and diaphragm samples from seropositive carcasses were processed for the presence of T. gondii DNA (B1 locus) by real-time PCR and high resolution melting (HRM) assay. Anti-Toxoplasma antibodies were detected in 2.1% of pig carcasses, with titers from 1:10 to 1:320. T. gondii DNA was detected in all (eight) seropositive carcasses and in 11 (5 heart and 6 diaphragm samples) of 16 samples; that is, it was detected in heart tissue in two subjects, in diaphragm tissue in three subjects, and in both muscle tissues in three subjects. Toxoplasma genotypes were determined in seven of eight carcasses: type III was identified in four carcasses, type II in two, and both III and II in one carcass. The serological findings and the molecular detection of T. gondii strains suggest that cured meat products obtained from industrially bred pigs may be potential sources of toxoplasmosis for humans. Our results provide novel, important information regarding the seroprevalence and molecular prevalence of T. gondii in intensively reared pigs within this specific region of Italy, particularly because Parma ham from this region is known and consumed worldwide. On-farm preventive measures combined with slaughterhouse monitoring of carcasses of pigs bred for cured meat production should never be overlooked to prevent the introduction of T. gondii into the food chain and to ensure safety for consumers of these products.

  18. The 2012 Emilia (Northern Italy) earthquake sequence: an attempt of historical reading (United States)

    Graziani, L.; Bernardini, F.; Castellano, C.; Del Mese, S.; Ercolani, E.; Rossi, A.; Tertulliani, A.; Vecchi, M.


    In May-June 2012, the Po Valley (Northern Italy) was struck by an earthquake sequence whose strongest event occurred on 20 May (Mw 5.9). The intensity values (Imax 7-8 EMS98) assessed through macroseismic field surveys seemed inappropriate to describe the whole range of effects observed, especially those to monumental heritage, which suffered very heavy damage and destruction. The observed intensities in fact were significantly lower than those we could have expected after a Mw 5.9 event for Italy. As magnitude-intensity regressions are mainly based on historical earthquake data, we handle this issue going back in time and debating the following hypotheses: (a) the 2012 Emilia earthquake sequence shows lower intensity values than expected because the affected urban context is more heterogeneous and much less vulnerable than that in the past; (b) some historical earthquakes, especially those that occurred centuries ago and are provided with little information, could show a tendency to be overestimated in intensity, and consequently in magnitude. In order to give consistency to such hypotheses, we have introduced, as a test, a dual historical reading of the 2012 Emilia earthquake sequence as if it had occurred in the past: the first reading refers to a period prior to the introduction of concrete in buildings assessing the intensity on traditional masonry buildings only. A further historical reading, assessed by using information on monumental buildings only, was performed, and it can be roughly referred to the XVI-XVII centuries. In both cases, intensity values tend to grow significantly. The results could have a relevant impact when considered for seismic hazard assessments if confirmed on a large scale.

  19. Life cycle assessment: an application to poplar for energy cultivated in Italy

    Directory of Open Access Journals (Sweden)

    Jacopo Bacenetti


    Full Text Available The development of the bioenergy sector has led to an increasing interest in energy crops. Short rotation coppices (SRC are forestry management systems in which fast-growing tree species are produced under intensive cultivation practices to obtain high wood chips yields. In Italy, most SRC plantations consist of poplar biomass-clones. SRC plantations can be carried out with different management systems with diverse cutting times; consequently, the cultivation system can be crucial for attaining high yields depending on: i short and ii medium cutting frequency. Nowadays, the larger part of Italian SRC is based on 2-year cutting short rotation forestry (SRF but the best quality of wood chips is linked to 5-year plantation medium rotation forestry (MRF. This work compares an SRF and an MRF poplar plantation located in the Po Valley in northern Italy. In particular, a life cycle assessment (LCA was carried out to evaluate their energy demand and greenhouse gas emissions. The LCA software SimaPro 7.10 was used to create the LCA model and to assure an accurate impact assessment calculation. The analysis shows several differences between MRF and SRF in terms of fertiliser requirements and intensive agricultural activities. Results highlight that MRF produces a more sustainable wood chip production than SRF according to energy and environmental concerns. Furthermore, hot spots were identified in both SRF and MRF due to the high energy consumption and the related emissions. These hot spots were: i mineral fertilisation; ii mechanical weed-control; iii harvesting and biomass transport.

  10. Hoopa Valley Small Scale Hydroelectric Feasibility Project

    Energy Technology Data Exchange (ETDEWEB)

    Curtis Miller


    This study considered assessing the feasibility of developing small scale hydro-electric power from seven major tributaries within the Hoopa Valley Indian Reservation of Northern California ( This study pursued the assessment of seven major tributaries of the Reservation that flow into the Trinity River. The feasibility of hydropower on the Hoopa Valley Indian Reservation has real potential for development and many alternative options for project locations, designs, operations and financing. In order to realize this opportunity further will require at least 2-3 years of intense data collection focusing on stream flow measurements at multiple locations in order to quantify real power potential. This also includes on the ground stream gradient surveys, road access planning and grid connectivity to PG&E for sale of electricity. Imperative to this effort is the need for negotiations between the Hoopa Tribal Council and PG&E to take place in order to finalize the power rate the Tribe will receive through any wholesale agreement that utilizes the alternative energy generated on the Reservation.

  11. Salts in the dry valleys of Antartica (United States)

    Gibson, E. K., Jr.; Presley, B. J.; Hatfield, J.


    The Dry Valleys of Antarctica are examples of polar deserts which are rare geological features on the Earth. Such deserts typically have high salinities associated with their closed-basin waters and on many surficial materials throughout them. In order to examine the possible sources for the salts observed in association with the soils in the Dry Valleys. The chloride and bromide concentrations of the water leachates from 58 soils and core samples were measured. The Cl/Br ratio for seawater is 289 and ratios measured for most of the 58 soils studied (greater than 85% of the soils studied) was larger than the seawater ratio (ratios typically were greater than 1000 and ranged up to 50,000). The enrichment in Cl relative to Br is strong evidence that the alts present within the soils were derived from seawater during ordinary evaporation processes, and not from the deposition of Cl and Br from aerosols or from rock weathering as has often been suggested.

  12. Geddes, Zoos and the Valley Section

    Directory of Open Access Journals (Sweden)

    Catherine Thompson


    Full Text Available The development of Edinburgh Zoological Garden was a pioneering example of the modern approach to animal display, placing animals in naturalistic settings that demanded innovative landscape design. The concept for Edinburgh Zoo, opened in 1913, was devised by Patrick Geddes and developed in collaboration with Frank C Mears and Geddes's daughter, Norah. This paper draws on Welter's (2002 important study of Geddes's vision of the city and on Geddes biographies, as well as on original archive material, to explore aspects of Geddes's vision for landscape architecture in the early twentieth century. The paper discusses Geddes's contribution to contemporary design and planning theory through the concept of the valley section, which comes to an understanding of the global through the local and in turn inspires a vision of the universal. Geddes was influenced by Hagenbeck's design for his zoo, near Hamburg, and by the New York Zoological Park, in developing displays for Edinburgh zoo that attempted to show animal behaviour as it would be in its natural habitat. The work of the German evolutionary biologist, Ernst Haeckel, further inspired Geddes to conceptualise the design as one where, just as ontogeny recapitulates phylogeny, so human civilisation might be recapitulated. He developed a three-dimensional expression of his hypothetical 'valley section' as a model for interaction between life and the environment. The zoo 'within' a city becomes a model for the ideal city, a city 'within' its region, reflecting the highest attainment of human development, yet still linked to the most primitive of origins.

  13. Italy and the history of preventive conservation

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

  14. Internal mobility in Italy: A new delay

    Directory of Open Access Journals (Sweden)

    Reynaud Cecilia


    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.

  15. Botulism in Italy, 1986 to 2015. (United States)

    Anniballi, Fabrizio; Auricchio, Bruna; Fiore, Alfonsina; Lonati, Davide; Locatelli, Carlo Alessandro; Lista, Florigio; Fillo, Silvia; Mandarino, Giuseppina; De Medici, Dario


    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.

  16. Vitamin D deficiency in refugees in Italy

    Directory of Open Access Journals (Sweden)

    L.G. De Filippis


    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.

  17. Sangiovese and its offspring in southern Italy. (United States)

    Gasparro, Marica; Caputo, Angelo Raffaele; Bergamini, Carlo; Crupi, Pasquale; Cardone, Maria Francesca; Perniola, Rocco; Antonacci, Donato


    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.

    Vieno, Alessio; Lenzi, Michela; Gini, Gianluca; Pozzoli, Tiziana; Cavallo, Franco; Santinello, Massimo


    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.

  19. Geology and water resources of Owens Valley, California (United States)

    Hollett, Kenneth J.; Danskin, Wesley R.; McCaffrey, William F.; Walti, Caryl L.


    Owens Valley, a long, narrow valley located along the east flank of the Sierra Nevada in east-central California, is the main source of water for the city of Los Angeles. The city diverts most of the surface water in the valley into the Owens River-Los Angeles Aqueduct system, which transports the water more than 200 miles south to areas of distribution and use. Additionally, ground water is pumped or flows from wells to supplement the surface-water diversions to the river-aqueduct system. Pumpage from wells needed to supplement water export has increased since 1970, when a second aqueduct was put into service, and local concerns have been expressed that the increased pumpage may have had a detrimental effect on the environment and the indigenous alkaline scrub and meadow plant communities in the valley. The scrub and meadow communities depend on soil moisture derived from precipitation and the unconfined part of a multilayered aquifer system. This report, which describes the hydrogeology of the aquifer system and the water resources of the valley, is one in a series designed to (1) evaluate the effects that groundwater pumping has on scrub and meadow communities and (2) appraise alternative strategies to mitigate any adverse effects caused by, pumping. Two principal topographic features are the surface expression of the geologic framework--the high, prominent mountains on the east and west sides of the valley and the long, narrow intermountain valley floor. The mountains are composed of sedimentary, granitic, and metamorphic rocks, mantled in part by volcanic rocks as well as by glacial, talus, and fluvial deposits. The valley floor is underlain by valley fill that consists of unconsolidated to moderately consolidated alluvial fan, transition-zone, glacial and talus, and fluvial and lacustrine deposits. The valley fill also includes interlayered recent volcanic flows and pyroclastic rocks. The bedrock surface beneath the valley fill is a narrow, steep-sided graben

  1. Detection of valley polarization in graphene by a superconducting contact. (United States)

    Akhmerov, A R; Beenakker, C W J


    Because the valleys in the band structure of graphene are related by time-reversal symmetry, electrons from one valley are reflected as holes from the other valley at the junction with a superconductor. We show how this Andreev reflection can be used to detect the valley polarization of edge states produced by a magnetic field. In the absence of intervalley relaxation, the conductance GNS=(2e2/h)(1-cosTheta) of the junction on the lowest quantum Hall plateau is entirely determined by the angle Theta between the valley isospins of the edge states approaching and leaving the superconductor. If the superconductor covers a single edge, Theta=0 and no current can enter the superconductor. A measurement of GNS then determines the intervalley relaxation time.

    Full Text Available Abstract The diet of the stone marten (Martes foina was studied analysing 63 faeces collected from February 1990 to December 1991. The results were expressed as relative percentage of frequency (Fr% and as percentage of mean bulk (Vm%. Mammals, mainly rodents, were the staple in the diet (annual Vm% = 62.9 and reached a maximum peak in winter (Vm% = 79.4. Vegetables were mostly represented by Rosaceae fruits (annual Vm% = 22.3 and were consumed during all year round. Insects, mainly Coleoptera and Orthoptera, were fairly frequently eaten, although their volume was not remarkable (annual Vm% = 4.1. Birds and garbage were scarcely used. The trophic niche breadth of the stone marten, evaluated using the Levin's index (B, varied from 2.49 in winter to 4.8 in summer.

  3. Sedimentological and geochimical features of chaotic deposits in the Ventimiglia Flysch (Roya-Argentina valley- NW Italy) (United States)

    Perotti, Elena; Bertok, Carlo; D'Atri, Anna; Martire, Luca; Musso, Alessia; Piana, Fabrizio; Varrone, Dario


    The Ventimiglia Flysch is a Upper Eocene turbidite succession deposited in the SE part of the Eocene Alpine foreland basin, truncated at the top by the basal thrust of the Helminthoides Flysch, a Ligurian tectonic unit that presently covers part of the Dauphinois and Briançonnais successions of Western Ligurian Alps. The Ventimiglia Flysch is made of alternations of sandstones and shales. The upper part is characterized by chaotic deposits. The chaotic deposits are constituted by: - km to hm-sized intrabasinal blocks (Ventimiglia Flysch) and extrabasinal blocks (Cretaceous sediments of Dauphinois Domain, Nummulite Limestone of the Alpine foreland basin and Helminthoides Flysch ); - conglomerates with block-in-matrix fabric interpreted as debris flow deposits. They occur as m-thick beds interbedded with the normal turbidite succession or locally as matrix of the larger blocks. Debris flow clasts show: - different sizes, ranging from metre to centimetre; - different shapes, from rounded to subangular; - different lithologies, such as fine-grained quartz-arenites, marls, dark shales and fine-grained calcisiltites. They may be referred to both coeval, intrabasinal lithologies (Ventimiglia Flysch), and extrabasinal formations (Nummulite Limestone, Globigerina Marl and Helminthoides Flysch). The clasts are disposed randomly into a chaotic matrix that consists of a dark mudstone in which submillimetre- to millimetre-sized lithic grains, with the same compositions of larger clasts, are present. Locally matrix consists of sandstones with quartz and feldspar grains and fragments of nummulitids that suggest reworking of unlithified Eocene sediments. Cathodoluminescence observations allow the distinction of two kinds of clasts: dull clasts that underwent a cementation before the formation of conglomerates, and clasts with the same orange luminescence as the matrix that may be interpreted as soft mud clasts that were cemented together with the matrix. Debris flow deposits are cross-cut by a network of crumpled and broken veins, 10's mm to cm-large, filled with orange luminescing calcite and locally with quartz. Their complex cross-cutting relationships with clasts and matrix show that several systems of veins are present, that may be referred to different fracturing events. Some clasts are crossed or bordered by veins that end at the edge of the clasts. These veins show the same features as those that crosscut the whole rock. This indicates reworking of plastic sediments crossed by calcite-filled veins by mass gravity flows. Polyphase debris flow processes, proceeding along with fluid expulsion and veining, are thus documented. Ellipsoidal, dm-large concretions of cemented pelites also occur. They represent a previous phase of concretionary growth within homogenous pelites subsequently involved in the mass gravity flow. Stable O and C isotope analyses, performed on matrix, clasts, concretions and veins, show: - δ13C close to normal marine values (-3 to 0 δ13C ‰ PDB) - δ18O markedly negative (-9 to -7 δ18O ‰ PDB) that could be related to precipitation from relatively hot waters (60-70 ° C). The block-in-matrix fabric and the variable composition and size of blocks show that these sediments are a sedimentary mélange related to mass wasting processes involving both extrabasinal and intrabasinal sediments. These gravitational movements took place along slopes of submarine tectonic ridges created by transpressional faults (Piana et al., 2009) that juxtaposed tectonic slices of different paleogeographic domains (Dauphinois, Briançonnais, Ligurian Units) in Late Eocene times, and involved both rock fall processes of huge blocks of lithified, older formations, and debris flows of unlithified intrabasinal sediment. Faults also acted as conduits for an upward flow of hot fluids supersaturated in calcium carbonate. These fluids crossed unlithified sediments close to the sea floor resulting in localized concretionary cementation and formation of vein swarms within unlithified sediments prone to subsequent mass wasting.

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

    Donatella Abbate Badin


    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.

  5. Fracture controls on valley persistence: the Cairngorm Granite pluton, Scotland (United States)

    Hall, A. M.; Gillespie, M. R.


    Valleys are remarkably persistent features in many different tectonic settings, but the reasons for this persistence are rarely explored. Here, we examine the structural controls on valleys in the Cairngorms Mountains, Scotland, part of the passive margin of the eastern North Atlantic. We consider valleys at three scales: straths, glens and headwater valleys. The structural controls on valleys in and around the Cairngorm Granite pluton were examined on satellite and aerial photographs and by field survey. Topographic lineaments, including valleys, show no consistent orientation with joint sets or with sheets of microgranite and pegmatitic granite. In this granite landscape, jointing is not a first-order control on valley development. Instead, glens and headwater valleys align closely to quartz veins and linear alteration zones (LAZs). LAZs are zones of weakness in the granite pluton in which late-stage hydrothermal alteration and hydro-fracturing have greatly reduced rock mass strength and increased permeability. LAZs, which can be kilometres long and >700 m deep, are the dominant controls on the orientation of valleys in the Cairngorms. LAZs formed in the roof zone of the granite intrusion. Although the Cairngorm pluton was unroofed soon after emplacement, the presence of Old Red Sandstone (ORS) outliers in the terrain to the north and east indicates that the lower relief of the sub-ORS basement surface has been lowered by 1 km of vertical erosion and for 400 Myr. This valley persistence is a combined product of regionally low rates of basement exhumation and of the existence of LAZs in the Cairngorm pluton and sub-parallel Caledonide fractures in the surrounding terrain with depths that exceed 1 km.

    Full Text Available We revise the chronostratigraphy of several sedimentary successions cropping out along a 5 km-long tract of the Aniene River Valley in Rome (Italy, which yielded six hominin remains previously attributed to proto- or archaic Neanderthal individuals, as well as a large number of lithic artefacts showing intermediate characteristics somewhere between the local Acheulean and Mousterian cultures. Through a method of correlation of aggradational successions with post-glacial sea-level rises, relying on a large set of published 40Ar/39Ar ages of interbedded volcanic deposits, we demonstrate that deposition of the sediments hosting the human remains spans the interval 295-220 ka. This is consistent with other well constrained ages for lithic industries recovered in England, displaying transitional features from Lower to Middle Paleolithic, suggesting the appearance of Mode 3 during the MIS 9-MIS 8 transition. Moreover, the six human bone fragments recovered in the Aniene Valley should be regarded as the most precisely dated and oldest hominin remains ascribable to Neanderthal-type individuals in Europe, discovered to date. The chronostratigraphic study presented here constitutes the groundwork for addressing re-analysis of these remains and of their associated lithic industries, in the light of their well-constrained chronological picture.

    The Ficoncella site in northern Latium (Italy) represents a unique opportunity to investigate the modalities of a short occupation in an alluvial setting during the Lower Palaeolithic. The small excavation area yielded a lithic assemblage, a carcass of Palaeoloxodon antiquus, and some other faunal remains. The main objectives of the study are to better characterize the depositional context where the Palaeoloxodon and the lithic assemblage occur, and to evaluate with greater precision the occupation dynamics. A 25 m-long well was drilled just above the top of the terrace of the Ficoncella site and faunal and lithic remains were analyzed with current and innovative techniques. The archaeological site contains floodplain deposits as it is located next to a small incised valley that feeds into a larger valley of the Mignone River. A tephra layer capping the site is 40Ar/39Ar dated to 441± 8 ka. Collectively, the geochronologic, tephrochronologic and geologic data, suggest the site was occupied during MIS 13. The new results should prompt further research at Ficoncella in order to improve our understanding of the dynamics of human settlement in Europe during the Early to Middle Pleistocene.

  11. Water resources of Parowan Valley, Iron County, Utah (United States)

    Marston, Thomas M.


    Parowan Valley, in Iron County, Utah, covers about 160 square miles west of the Red Cliffs and includes the towns of Parowan, Paragonah, and Summit. The valley is a structural depression formed by northwest-trending faults and is, essentially, a closed surface-water basin although a small part of the valley at the southwestern end drains into the adjacent Cedar Valley. Groundwater occurs in and has been developed mainly from the unconsolidated basin-fill aquifer. Long-term downward trends in groundwater levels have been documented by the U.S. Geological Survey (USGS) since the mid-1950s. The water resources of Parowan Valley were assessed during 2012 to 2014 with an emphasis on refining the understanding of the groundwater and surface-water systems and updating the groundwater budget.Surface-water discharge of five perennial mountain streams that enter Parowan Valley was measured from 2013 to 2014. The total annual surface-water discharge of the five streams during 2013 to 2014 was about 18,000 acre-feet (acre-ft) compared to the average annual streamflow of about 22,000 acre-ft from USGS streamgages operated on the three largest of these streams from the 1940s to the 1980s. The largest stream, Parowan Creek, contributes more than 50 percent of the annual surface-water discharge to the valley, with smaller amounts contributed by Red, Summit, Little, and Cottonwood Creeks.Average annual recharge to the Parowan Valley groundwater system was estimated to be about 25,000 acre-ft from 1994 to 2013. Nearly all recharge occurs as direct infiltration of snowmelt and rainfall on the Markagunt Plateau east of the valley. Smaller amounts of recharge occur as infiltration of streamflow and unconsumed irrigation water near the east side of the valley on alluvial fans associated with mountain streams at the foot of the Red Cliffs. Subsurface flow from the mountain block to the east of the valley is a significant source of groundwater recharge to the basin-fill aquifer

  12. Soil-plant-atmosphere processes along an elevation gradient in a dry alpine valley (United States)

    Della Chiesa, Stefano; Bertoldi, Giacomo; Niedrist, Georg Georg; Tappeiner, Ulrike


    In mountain regions soil-plant-atmosphere processes exhibit rapid changes within short distance due to the complex pattern of topography and atmospheric processes. An elevation transect can be seen as a proxy of climate change (CC), as it affects air temperature, precipitation amount and its partitioning into snow and rain, snow cover duration, and the resulting changing length of vegetation period. In order to quantitatively investigate the exchange of energy, water and carbon with respect to elevation for mountain grassland ecosystems within an inner dry alpine valley, a transect of three micro-meteorological stations was established since 2009 in the Venosta valley (South Tyrol, Italy). It has been designed with three stations, with an elevation difference among the stations of 500 m, which means an average temperature gradient of 2.7 K. In this contribution, the GEOtop-dv model was employed to simulate the effects of the elevation gradient on snow, soil moisture, evapotranspiration (ET) and above ground net primary production (ANPP) dynamics in two years with different climatic conditions. Simulations have been validated with observations of soil moisture, snow height, ANPP and eddy-covariance measured ET. Considering the observed contrasting natural trends of increasing precipitation and of decreasing temperature with higher elevation, numerical simulation results show that, in this type of climate, snow dynamics are highly nonlinear with the elevation due to differential precipitation partitioning in early winter and spring. Despite the relatively cold climatic conditions, soil moisture dynamics indicate that severe drought occurs in the bottom of the valley, while at the higher elevations cold temperatures limit growing season duration, and therefore ET and ANPP. Those contrasting trends result in an optimal altitude at about 1400 m a.s.l., where temperature and water availability are optimal in terms of maximum annual ET and ANPP. Our results indicate that

    Full Text Available Abstract Background In the years 2003–2005 research was carried out concerning ethno-medicine in the high Molise (central- southern Italy, a region that has been the object of very little investigation from the ethnobotanical point of view. Upper Molise is a continuation of the mountain profiles of the Abruzzi Appenines: a series of hills, steep slopes and deep fluvial valleys making communications difficult. Primordial traditions (e.g. harvest feasts are typical of the region. Methods Field data were collected through open interviews in the field. These were conducted on both an individual and group level, fresh plants gathered from surrounding areas being displayed. In other cases, individual interviews were conducted by accompanying the person involved to the places where they perform their activities (for example, in the woods with woodcutters, kitchen gardens and fields with housewives, pastures with shepherds, etc.. In total 54 individuals were interviewed. Results Data of 70 taxa belonging to 39 families were gathered. Among the species, 64 are used in human therapy, 5 as insect repellents, 11 in veterinary medicine, 1 to keep eggs and cheeses and 4 for magic purposes. The most important findings in ethno-medicine relate to the lichen Lobaria pulmonaria (L. Hoffm. (wounds and to some vascular plant species: Asplenium trichomanes L. and Ceterach officinarum Willd.

  14. Hominin responses to environmental changes during the Middle Pleistocene in central and southern Italy

    Directory of Open Access Journals (Sweden)

    R. Orain


    Full Text Available The palaeobotanical record of early Palaeolithic sites from Western Europe indicates that hominins settled in different kinds of environments. During the "mid-Pleistocene transition (MPT", from about 1 to 0.6 Ma, the transition from 41- to 100-ka dominant climatic oscillations, occurring within a long-term cooling trend, was associated with an aridity crisis which strongly modified the ecosystems. Starting from the MPT the more favourable climate of central and southern Italy provided propitious environmental conditions for long-term human occupations even during the glacial times. In fact, the human strategy of territory occupation was certainly driven by the availabilities of resources. Prehistoric sites such as Notarchirico (ca. 680–600 ka, La Pineta (ca. 600–620 ka, Guado San Nicola (ca. 380–350 ka or Ceprano (ca. 345–355 ka testify to a preferential occupation of the central and southern Apennines valleys during interglacial phases, while later interglacial occupations were oriented towards the coastal plains, as attested by the numerous settlements of the Roma Basin (ca. 300 ka. Faunal remains indicate that human subsistence behaviours benefited from a diversity of exploitable ecosystems, from semi-open to closed environments. In central and southern Italy, several palynological records have already illustrated the regional- and local-scale vegetation dynamic trends. During the Middle Pleistocene climate cycles, mixed mesophytic forests developed during the interglacial periods and withdrew in response to increasing aridity during the glacial episodes. New pollen data from the Boiano Basin (Molise, Italy attest to the evolution of vegetation and climate between MIS 13 and 9 (ca. 500 to 300 ka. In this basin the persistence of high edaphic humidity, even during the glacial phases, could have favoured the establishment of a refuge area for the arboreal flora and provided subsistence resources for the animal and hominin communities

  15. Stakeholder discourse and water management in a catchment in northern Italy (United States)

    Lupo Stanghellini, P. S.; Collentine, D.


    The Water Framework Directive (WFD; directive 2000/60/EC) was created to ensure the sustainable use of water resources in the European Union. A central guideline included throughout the directive is a call for the participation of stakeholders in the management of these resources. Involving stakeholders is an important step to ensure that catchment management plans take into consideration local experience in the development of these plans and the impact of the plans on local interests. This paper describes and analyses the results of a series of workshops to facilitate implementation of the WFD at a catchment level based on the stakeholder participation model, CATCH. To test the usefulness of the stakeholder participation model CATCH for water management in a catchment area, a sub-catchment in an alpine valley in the north-east of Italy, the Alta Valsugana in the Province of Trento, was chosen as the setting for a series of workshops. In this valley water is fundamental for activities associated with agriculture, domestic use, energy production, sports and recreation. In the recent past the valley has had serious problems related to water quality and quantity. Implementation of water management plans under the WFD may lead to conflicts within the catchment between different stakeholder interest groups. Including stakeholders in the development of management plans not only follows the guidelines of the WFD but also could result in a more locally adapted and acceptable plan for the catchment. A new stakeholder analysis methodology was developed and implemented in order to identify the relevant stakeholders of the area and then two sets of workshops involving the key stakeholders identified were conducted in Spring 2006. The CATCH meetings were a new experience for the participants, who had to deal with both the principles of the WFD in general and the participation requirement in particular. During the meetings, the CATCH model played a very important role in

    Angelo Salento


    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.

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

    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.)

  1. An epidemiological model of Rift Valley fever

    Directory of Open Access Journals (Sweden)

    Nicole P. Leahy


    Full Text Available We present and explore a novel mathematical model of the epidemiology of Rift Valley Fever (RVF. RVF is an Old World, mosquito-borne disease affecting both livestock and humans. The model is an ordinary differential equation model for two populations of mosquito species, those that can transmit vertically and those that cannot, and for one livestock population. We analyze the model to find the stability of the disease-free equlibrium and test which model parameters affect this stability most significantly. This model is the basis for future research into the predication of future outbreaks in the Old World and the assessment of the threat of introduction into the New World.

    To elucidate whether Rift Valley fever virus (RVFV) diversity in Sudan resulted from multiple introductions or from acquired changes over time from 1 introduction event, we generated complete genome sequences from RVFV strains detected during the 2007 and 2010 outbreaks. Phylogenetic analyses of small, medium, and large RNA segment sequences indicated several genetic RVFV variants were circulating in Sudan, which all grouped into Kenya-1 or Kenya-2 sublineages from the 2006–2008 eastern Africa epizootic. Bayesian analysis of sequence differences estimated that diversity among the 2007 and 2010 Sudan RVFV variants shared a most recent common ancestor circa 1996. The data suggest multiple introductions of RVFV into Sudan as part of sweeping epizootics from eastern Africa. The sequences indicate recent movement of RVFV and support the need for surveillance to recognize when and where RVFV circulates between epidemics, which can make data from prediction tools easier to interpret and preventive measures easier to direct toward high-risk areas.

  3. Direct measurement of exciton valley coherence in monolayer WSe2

    KAUST Repository

    Hao, Kai


    In crystals, energy band extrema in momentum space can be identified by a valley index. The internal quantum degree of freedom associated with valley pseudospin indices can act as a useful information carrier, analogous to electronic charge or spin. Interest in valleytronics has been revived in recent years following the discovery of atomically thin materials such as graphene and transition metal dichalcogenides. However, the valley coherence time—a crucial quantity for valley pseudospin manipulation—is difficult to directly probe. In this work, we use two-dimensional coherent spectroscopy to resonantly generate and detect valley coherence of excitons (Coulomb-bound electron–hole pairs) in monolayer WSe2 (refs ,). The imposed valley coherence persists for approximately one hundred femtoseconds. We propose that the electron–hole exchange interaction provides an important decoherence mechanism in addition to exciton population recombination. This work provides critical insight into the requirements and strategies for optical manipulation of the valley pseudospin for future valleytronics applications.

  4. Origin and evolution of valleys on Martian volcanoes

    Energy Technology Data Exchange (ETDEWEB)

    Gulick, V.C.; Baker, V.R. (Univ. of Arizona, Tucson (USA))


    Morphological analyses of six Martian volcanoes, Ceraunius Tholus, Hecates Tholus, Alba Patera, Hadriaca Patera, Apollinaris Patera, and Tyrrhena Patera, indicate that fluvial processes were the dominant influence in the initiation and subsequent development of many dissecting valleys. Lava processes and possibly volcanic density flows were also important as valley-forming processes. Fluvial valleys are especially well developed on Alba Patera, Ceraunius Tholus, and Hecates Tholus. These valleys are inset into the surrounding landscape. They formed in regions of subdued lava flow morphology, contain tributaries, and tend to widen slightly in the downstream direction. Lava channels on Alba Patera are located on the crest of lava flows and have a discontinuous, irregular surface morphology, and distributary patterns. These channels sometimes narrow toward their termini. Possible volcanic density flow channels are located on the northern flank of Ceraunius Tholus. Valleys dissecting Apollinaris Patera, Hadriaca Patera, and Tyrrhena Patera appear to have a complex evolution, probably a mixed fluvial and lava origin. They are inset into a subdued (possibly mantled) surface, lack tributaries, and either have fairly constant widths or widen slightly downvalley. Valleys surrounding the caldera of Apollinaris appear to have formed by fluvial and possibly by volcanic density flow processes, while those on the Apollinaris fan structure may have a mixed lava and fluvial origin. Valleys on Tyrrhena have broad flat floors and theater heads, which have been extensively enlarged, probably by sapping.

    Electron valley, a degree of freedom that is analogous to spin, can lead to novel topological phases in bilayer graphene. A tunable bandgap can be induced in bilayer graphene by an external electric field, and such gapped bilayer graphene is predicted to be a topological insulating phase protected by no-valley mixing symmetry, featuring quantum valley Hall effects and chiral edge states. Observation of such chiral edge states, however, is challenging because inter-valley scattering is induced by atomic-scale defects at real bilayer graphene edges. Recent theoretical work has shown that domain walls between AB- and BA-stacked bilayer graphene can support protected chiral edge states of quantum valley Hall insulators. Here we report an experimental observation of ballistic (that is, with no scattering of electrons) conducting channels at bilayer graphene domain walls. We employ near-field infrared nanometre-scale microscopy (nanoscopy) to image in situ bilayer graphene layer-stacking domain walls on device substrates, and we fabricate dual-gated field effect transistors based on the domain walls. Unlike single-domain bilayer graphene, which shows gapped insulating behaviour under a vertical electrical field, bilayer graphene domain walls feature one-dimensional valley-polarized conducting channels with a ballistic length of about 400 nanometres at 4 kelvin. Such topologically protected one-dimensional chiral states at bilayer graphene domain walls open up opportunities for exploring unique topological phases and valley physics in graphene.

  6. Geothermal hydrology of Warner Valley, Oregon: a reconnaissance study

    Energy Technology Data Exchange (ETDEWEB)

    Sammel, E.A.; Craig, R.W.


    Warner Valley and its southern extension, Coleman Valley, are two of several high-desert valleys in the Basin and Range province of south-central Oregon that contain thermal waters. At least 20 thermal springs, defined as having temperatures of 20/sup 0/C or more, issue from Tertiary basaltic flows and tuffs in and near the valleys. Many shallow wells also produce thermal waters. The highest measured temperature is 127/sup 0/C, reported from a well known as Crump geyser, at a depth of 200 meters. The hottest spring, located near Crump geyser, has a surface temperature of 78/sup 0/C. The occurrence of these thermal waters is closely related to faults and fault intersections in the graben and horst structure of the valleys. Chemical analyses show that the thermal waters are of two types: sodium chloride and sodium bicarbonate waters. Chemical indicators show that the geothermal system is a hot-water rather than a vapor-dominated system. Conductive heat flow in areas of the valley unaffected by hydrothermal convection is probably about 75 milliwatts per square meter. The normal thermal gradient in valley-fill dpeosits in these areas may be about 40/sup 0/C per kilometer. Geothermometers and mixing models indicate that temperatures of equilibration are at least 170/sup 0/C for the thermal components of the hotter waters. The size and location of geothermal reservoirs are unknown.

  7. GPR Activities in Italy: a Review (United States)

    Tosti, Fabio; Ambrosanio, Michele; Battaglia, Enzo; Bianchini Ciampoli, Luca; De Carlo, Lorenzo; Matera, Loredana; Prontera, Santo; Sileo, Maria


    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

  8. Perspectives of offshore geothermal energy in Italy (United States)

    Armani, F. B.; Paltrinieri, D.


    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.

  10. Biological monitoring of aquatic ecosystems in Italy

    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.

  11. Adaptively Smoothed Seismicity Earthquake Forecasts for Italy

    CERN Document Server

    Werner, M J; Jackson, D D; Kagan, Y Y; Wiemer, S


    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...

  12. An agreement for applied research in Italy

    CERN Multimedia


    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.

  14. Women and botany in Risorgimento Italy. (United States)

    Logan, Gabriella Berti


    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.

  16. Veneto Region, Italy. Health system review. (United States)

    Toniolo, Franco; Mantoan, Domenico; Maresso, Anna


    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.

  17. Functional ecology of an Antarctic Dry Valley (United States)

    Chan, Yuki; Van Nostrand, Joy D.; Zhou, Jizhong; Pointing, Stephen B.


    The McMurdo Dry Valleys are the largest ice-free region in Antarctica and are critically at risk from climate change. The terrestrial landscape is dominated by oligotrophic mineral soils and extensive exposed rocky surfaces where biota are largely restricted to microbial communities, although their ability to perform the majority of geobiological processes has remained largely uncharacterized. Here, we identified functional traits that drive microbial survival and community assembly, using a metagenomic approach with GeoChip-based functional gene arrays to establish metabolic capabilities in communities inhabiting soil and rock surface niches in McKelvey Valley. Major pathways in primary metabolism were identified, indicating significant plasticity in autotrophic, heterotrophic, and diazotrophic strategies supporting microbial communities. This represents a major advance beyond biodiversity surveys in that we have now identified how putative functional ecology drives microbial community assembly. Significant differences were apparent between open soil, hypolithic, chasmoendolithic, and cryptoendolithic communities. A suite of previously unappreciated Antarctic microbial stress response pathways, thermal, osmotic, and nutrient limitation responses were identified and related to environmental stressors, offering tangible clues to the mechanisms behind the enduring success of microorganisms in this seemingly inhospitable terrain. Rocky substrates exposed to larger fluctuations in environmental stress supported greater functional diversity in stress-response pathways than soils. Soils comprised a unique reservoir of genes involved in transformation of organic hydrocarbons and lignin-like degradative pathways. This has major implications for the evolutionary origin of the organisms, turnover of recalcitrant substrates in Antarctic soils, and predicting future responses to anthropogenic pollution.

  19. Human visceral leishmaniasis: a picture from Italy. (United States)

    Abdalmaula, Giuma Harun; Barbadoro, Pamela; Marigliano, Anna; Illuminati, Diego; Di Stanislao, Francesco; D'Errico, Marcello Mario; Prospero, Emilia


    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.

  20. New records of Coenagrion ornatum in Italy (Odonata: Coenagrionidae

    Directory of Open Access Journals (Sweden)

    Fabio Mastropasqua


    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.

  1. Bangladeshi immigrants in Italy: from geopolitics to micropolitics. (United States)

    Knights, M


    "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

  2. Elemental characterization, sources and wind dependence of PM1 near Venice, Italy (United States)

    Valotto, Gabrio; Squizzato, Stefania; Masiol, Mauro; Zannoni, Daniele; Visin, Flavia; Rampazzo, Giancarlo


    In this paper, PM1 elemental composition and relative sources have been investigated near Venice (Eastern Po Valley, Italy). Considering the lack of information on PM1 composition in this area and the general poor knowledge of emission profiles, this study can give useful information to better understand the source profile and the dispersion of finer particles. A sampling campaign was carried out in two sampling sites located inside the "Marco Polo" international airport of Venice. Elemental composition on PM1 samples was characterized by inductively coupled plasma optical emission spectroscopy. Five sources were identified and quantified by using the positive matrix factorization receptor model: heavy oil combustion, road traffic, airplane tire-wear, glassmaking and mixed combustions. The role of local atmospheric circulation was investigated by studying the source contributions as a function of wind velocity. Days characterized by low dispersion (lower wind speed and higher wind calm with respect to full period rose) showed a higher contribution for all sources, and a glassmaking contribution increase linked to wind blowing from South, where the artistic glass district of Venice is located.

  3. Geomorphic evidence of Quaternary tectonics within an underlap fault zone of southern Apennines, Italy (United States)

    Giano, Salvatore Ivo; Pescatore, Eva; Agosta, Fabrizio; Prosser, Giacomo


    A composite seismic source, the Irpinia - Agri Valley Fault zone, located in the axial sector of the fold-and-thrust belt of southern Apennines, Italy, is investigated. This composite source is made up of a series of nearly parallel, NW-striking normal fault segments which caused many historical earthquakes. Two of these fault segments, known as the San Gregorio Magno and Pergola-Melandro, and the fault-related mountain fronts, form a wedge-shaped, right-stepping, underlap fault zone. This work is aimed at documenting tectonic geomorphology and geology of this underlap fault zone. The goal is to decipher the evidence of surface topographic interaction between two bounding fault segments and their related mountain fronts. In particular, computation of geomorphic indices such as mountain front sinuosity (Smf), water divide sinuosity (Swd), asymmetry factor (AF), drainage basin elongation (Bs), relief ratio (Rh), Hypsometry (HI), normalized steepness (Ksn), and concavity (θ) is integrated with geomorphological analysis, the geological mapping, and structural analysis in order to assess the recent activity of the fault scarp sets recognized within the underlap zone. Results are consistent with the NW-striking faults as those showing the most recent tectonic activity, as also suggested by presence of related slope deposits younger than 38 ka. The results of this work therefore show how the integration of a multidisciplinary approach that combines geomorphology, morphometry, and structural analyses may be key to solving tectonic geomorphology issues in a complex, fold-and-thrust belt configuration.

  4. Groundwater availability of the Central Valley Aquifer, California (United States)

    Faunt, Claudia C.


    California's Central Valley covers about 20,000 square miles and is one of the most productive agricultural regions in the world. More than 250 different crops are grown in the Central Valley with an estimated value of $17 billion per year. This irrigated agriculture relies heavily on surface-water diversions and groundwater pumpage. Approximately one-sixth of the Nation's irrigated land is in the Central Valley, and about one-fifth of the Nation's groundwater demand is supplied from its aquifers. The Central Valley also is rapidly becoming an important area for California's expanding urban population. Since 1980, the population of the Central Valley has nearly doubled from 2 million to 3.8 million people. The Census Bureau projects that the Central Valley's population will increase to 6 million people by 2020. This surge in population has increased the competition for water resources within the Central Valley and statewide, which likely will be exacerbated by anticipated reductions in deliveries of Colorado River water to southern California. In response to this competition for water, a number of water-related issues have gained prominence: conservation of agricultural land, conjunctive use, artificial recharge, hydrologic implications of land-use change, and effects of climate variability. To provide information to stakeholders addressing these issues, the USGS Groundwater Resources Program made a detailed assessment of groundwater availability of the Central Valley aquifer system, that includes: (1) the present status of groundwater resources; (2) how these resources have changed over time; and (3) tools to assess system responses to stresses from future human uses and climate variability and change. This effort builds on previous investigations, such as the USGS Central Valley Regional Aquifer System and Analysis (CV-RASA) project and several other groundwater studies in the Valley completed by Federal, State and local agencies at differing scales.

    Energy Technology Data Exchange (ETDEWEB)

    Mase, C.W.; Galanis, S.P. Jr.; Munroe, R.J.


    With the exception of values from one borehole drilled at Palm Spring and three boreholes drilled around Saline Valley dry lake, eight new heatflow values in Saline Valley, California, are within or somewhat below the range one would expect for this region of the Basin and Range heat-flow province. The lack of recent volcanism in the area and the apparently normal Basin and Range heat flow suggest that geothermal systems within the valley are stable stationary phases supported by high regional heat flow and forced convection.

  6. Valley-selective topologically ordered states in irradiated bilayer graphene (United States)

    Qu, Chunlei; Zhang, Chuanwei; Zhang, Fan


    Gapless bilayer graphene is susceptible to a variety of spontaneously gapped states. As predicted by theory and observed by experiment, the ground state is, however, topologically trivial, because a valley-independent gap is energetically favorable. Here, we show that under the application of interlayer electric field and circularly polarized light, one valley can be selected to exhibit the original interaction instability while the other is frozen out. Tuning this Floquet system stabilizes multiple competing topologically ordered states, distinguishable by edge transport and circular dichroism. Notably, quantized charge, spin, and valley Hall conductivities coexist in one stabilized state.

  7. Holocene alluvial fills in the South Loup Valley, Nebraska (United States)

    May, David W.


    Four Holocene alluvial fills are present in Nebraska's South Loup River valley. Fill IV, the oldest and thickest, was deposited between 10,200 and 4800 14C yr B.P.; Fill III has an age of about 3000 14C yr B.P.; Fill II is younger than 2100 and older than 900 14C yr B.P.; and Fill I is younger than 900 14C yr B.P. Regional contemporaneity of valley alluviation in the eastcentral Great Plains suggests that climate has controlled long-term sediment storage in the South Loup River valley.

  9. California's Central Valley Groundwater Study: A Powerful New Tool to Assess Water Resources in California's Central Valley (United States)

    Faunt, Claudia C.; Hanson, Randall T.; Belitz, Kenneth; Rogers, Laurel


    Competition for water resources is growing throughout California, particularly in the Central Valley. Since 1980, the Central Valley's population has nearly doubled to 3.8 million people. It is expected to increase to 6 million by 2020. Statewide population growth, anticipated reductions in Colorado River water deliveries, drought, and the ecological crisis in the Sacramento-San Joaquin Delta have created an intense demand for water. Tools and information can be used to help manage the Central Valley aquifer system, an important State and national resource.

    Yu Song


    Full Text Available We study spatial separation of the four degenerate spin-valley components of an electron beam in a EuO-induced and top-gated ferromagnetic/pristine/strained graphene structure. We show that, in a full resonant tunneling regime for all beam components, the formation of standing waves can lead sudden phase jumps ∼−π and giant lateral Goos-Hänchen shifts as large as the transverse beam width, while the interplay of the spin and valley imaginary wave vectors in the modulated regions can lead differences of resonant angles for the four spin-valley flavors, manifesting a spin-valley beam splitting effect. The splitting effect is found to be controllable by the gating and strain.

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

    Energy Technology Data Exchange (ETDEWEB)



    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

  12. Geology and ground-water resources of Ogden Valley, Utah (United States)

    Leggette, R.M.; Taylor, G.H.


    Ogden Valley is a fault trough bounded on both the east and west by faults that dip toward the middle of the valley. This fault trough contains unconsolidated deposits of clay, sand, and gravel, whose thickness is more than 600 feet. These materials are stream and lake deposits and in places are well sorted and stratified. The lake sediments were laid down in a small lake that occupied Ogden Valley and that was connected with glacial Lake Bonneville at its high stage by an arm of water that occupied Ogden Canyon. During this stage of Lake Bonneville the Ogden Valley was completely filled with lake sediments up to an altitude of about 4,900 feet. These sediments include about 70 feet of clay, sand, and gravel in alternating layers, below which is a bed of varved clay whose maximum thickness is about 70 feet. This clay is continuous under the lower parts of the valley and is the confining bed that produces the artesian conditions. Below the varved clay is a deposit of silt, sand, and gravel of unknown thickness, most of which is believed to be pre-Bonneville alluvium.In most summers the streams entering Ogden Valley are diverted for irrigation, and the upper parts of their channels are generally dry during the irrigation season. Lower down in the valley seepage water appears in the channels, and below these points there is continuous flow. The flow of the Ogden River increases as it passes through Ogden Canyon. This gain in flow is believed to be derived chiefly from ground-water seepage from the canyon walls, although there is probably some groundwater underflow from Ogden Valley at the head of Ogden Canyon. Some of the gain is also due to leakage from pipe lines in the canyon.Of the 146 wells whose records are given in this report, 70 are flowing wells.

    A ten-station seismic network was operated in and around the Dixie Valley area from January 1980 to November 1981; three of these stations are still in operation. Data from the Dixie Valley network were analyzed through 30 Jun 1981, and results of analysis were compared with analysis of somewhat larger events for the period 1970-1979. The seismic cycle in the Western Great Basic, the geologic structural setting, and the instrumentation are also described.

  15. 3D View of Death Valley, California (United States)


    This 3-D perspective view looking north over Death Valley, California, was produced by draping ASTER nighttime thermal infrared data over topographic data from the US Geological Survey. The ASTER data were acquired April 7, 2000 with the multi-spectral thermal infrared channels, and cover an area of 60 by 80 km (37 by 50 miles). Bands 13, 12, and 10 are displayed in red, green and blue respectively. The data have been computer enhanced to exaggerate the color variations that highlight differences in types of surface materials. Salt deposits on the floor of Death Valley appear in shades of yellow, green, purple, and pink, indicating presence of carbonate, sulfate, and chloride minerals. The Panamint Mtns. to the west, and the Black Mtns. to the east, are made up of sedimentary limestones, sandstones, shales, and metamorphic rocks. The bright red areas are dominated by the mineral quartz, such as is found in sandstones; green areas are limestones. In the lower center part of the image is Badwater, the lowest point in North America.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.The broad spectral coverage and high spectral resolution of ASTER will provide

  16. Estimated prevalence of multiple sclerosis in Italy in 2015. (United States)

    Battaglia, Mario Alberto; Bezzini, Daiana


    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.

  17. The 2016 Central Italy Earthquake: an Overview (United States)

    Amato, A.


    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

  18. Characterization of fire regime in Sardinia (Italy) (United States)

    Bacciu, V. M.; Salis, M.; Mastinu, S.; Masala, F.; Sirca, C.; Spano, D.


    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 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

  19. Organizational network in trauma management in Italy

    Directory of Open Access Journals (Sweden)

    Osvaldo Chiara


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

  1. Investigations on alluvial deposits through borehole stratigraphy, radiocarbon dating and passive seismic technique (Carnic Alps, NE Italy) (United States)

    Viero, Alessia; Marchi, Lorenzo; Cavalli, Marco; Crema, Stefano; Fontana, Alessandro; Mozzi, Paolo; Venturini, Corrado


    Alluvial sediment investigations provide fundamental tools to infer the processes that control geomorphological evolution of mountain environments. By analyzing sediment stratigraphy in depth, it is possible to retrieve the source, the geology, the time of deposition, the relative distance travelled by material as well as to distinguish among different type of transport (i.e., gravitational, fluvial or glacial). In this work, we present a combination of log stratigraphy, radiocarbon dating and geophysical surveys carried out on the valley floor of the But River (Carnic Alps, North East Italy). The But River basin drains an area of 326 km2 with a range in elevation from 2769 to 323 m a.s.l.; the bedrock mainly consists of carbonates and quartz arenites with minor inclusions of effusive rocks. After Pleistocene the gravitational deposits from mountain slopes have impounded the But River several times. In particular, we analyzed a sector of the upper portion of the But valley close to the confluence of the Moscardo Torrent, frequently affected by debris flows. A borehole was drilled in the But River floodplain, at the intersection with the Moscardo Torrent alluvial fan, down to a depth of 80 m. The analysis of the core samples allowed discerning three sedimentary levels rich in clay and organic materials, which testify the presence of small dam lakes, originated from the Moscardo debris-flow deposits. Three samples of wood and plant debris were collected from 13, 14 and 23 m of depth, respectively. They were analyzed through radiocarbon dating in order to determine the age of the lakes and, thus, to infer the activity of the debris flows building the Moscardo cone. The calibrated ages of the 3 samples are close to the younger limit of the radiocarbon method indicating a fast aggradation of the valley floor, starting from a period ranging between 1450 - 1632 AD. Historical maps and documents confirm the presence of the lakes until 19th century and they permit to assess

  2. Human civilisations, forest impact and river evolution in the Central Po plain (Mincio river system, N-Italy) during the last 3000 yr (United States)

    Zanon, Marco; Deaddis, Massimiliano; Perego, Renata; de Amicis, Mattia; Carlo de Marinis, Raffaele; Marchetti, Mauro; Quirino, Tommaso; Ravazzi, Cesare


    The evolution of the central Po plain (N-Italy) during the Holocene is the result of the interplay between fluvial dynamics, natural subsidence, sea level changes, forest cover, and, during the last four thousand years, of land use and exploitation. After a phase of lateglacial entranchement of the fluvioglacial plain, the alpine rivers tributaries of the Po river, among which the Mincio river, were constrained within their terraced valleys, so that the evolution of their valley floor was controlled by the dynamics of the Po river (i.e. the main river) and by the interplay of tectonics and subsidence. One of the most important of the Etruscan villages (Forcello, 16 m a.s.l., VI to IV century b.C.) settled along the valley floor of the Mincio river acted as a river harbour for fluviatile trades connecting the eastern Mediterranean Basin and continental Europe (De Marinis & Rapi, 2005). We presente here multidisciplinary stratigraphical and palaeoenvironmental evidence that this harbour actually rose on a large perifluvial lake (the "Bagnolo lake"), formed into the terraced valley at the beginning of the Iron Age. Independent archeological evidence suggests the lake was dammed by the main river, after diversions related to the "Iron age cold phase" alluvial events (VIII sec. b.C.). The diversion of the main river modified the fluviatile network of the lower alluvial plain, and promoted upstream shipping from the northern Adriatic till the Bagnolo perifluvial lake, were a main harbour was thus settled. The Bagnolo lake was kept until Middle Age reclaming, hence lacustrine sediments enregistered the forest history and human activities since the time of the Etruscan settlement till XIV century AD. A palynological and archeobotanical record, supported by radiocarbon dating on terrestrial macrofossils, testifies the Roman forest clearings and shows the unprecedented evidence of an early Middle Age phase of abandoning. Finally, an overall change in land use is dated at the

  3. Valley-selective optical Stark effect probed by Kerr rotation (United States)

    LaMountain, Trevor; Bergeron, Hadallia; Balla, Itamar; Stanev, Teodor K.; Hersam, Mark C.; Stern, Nathaniel P.


    The ability to monitor and control distinct states is at the heart of emerging quantum technologies. The valley pseudospin in transition metal dichalcogenide (TMDC) monolayers is a promising degree of freedom for such control, with the optical Stark effect allowing for valley-selective manipulation of energy levels in WS2 and WSe2 using ultrafast optical pulses. Despite these advances, understanding of valley-sensitive optical Stark shifts in TMDCs has been limited by reflectance-based detection methods where the signal is small and prone to background effects. More sensitive polarization-based spectroscopy is required to better probe ultrafast Stark shifts for all-optical manipulation of valley energy levels. Here, we show time-resolved Kerr rotation to be a more sensitive probe of the valley-selective optical Stark effect in monolayer TMDCs. Compared to the established time-resolved reflectance methods, Kerr rotation is less sensitive to background effects. Kerr rotation provides a fivefold improvement in the signal-to-noise ratio of the Stark effect optical signal and a more precise estimate of the energy shift. This increased sensitivity allows for observation of an optical Stark shift in monolayer MoS2 that exhibits both valley and energy selectivity, demonstrating the promise of this method for investigating this effect in other layered materials and heterostructures.

Grassroots criticism of the show arose, and a Valleys-centric campaign, The Valleys Are Here, took direct action. I adopt Jonathan Gray's definition of antifans to complicate ideas of fan activism. I utilize comments and posts made on the Valleys Are Here Twitter feed and Facebook account, as well as the organization's Web site, to examine the ways in which they encourage activism among antifans of the series. I pay particular attention to activist calls for MTV to be held accountable for its positioning of Wales and the Valleys, and to how it encourages participation among varied groups of people whose common denominator is their dislike of the series. Fan activism is not exclusive to people who consider themselves fans, and notions of fan activism can be complicated by drawing in antifans.

  6. Geothermal resource assessment of western San Luis Valley, Colorado

    Energy Technology Data Exchange (ETDEWEB)

    Zacharakis, Ted G.; Pearl, Richard Howard; Ringrose, Charles D.


    The Colorado Geological Survey initiated and carried out a fully integrated assessment program of the geothermal resource potential of the western San Luis Valley during 1979 and 1980. The San Luis Valley is a large intermontane basin located in southcentral Colorado. While thermal springs and wells are found throughout the Valley, the only thermal waters found along the western part of the Valley are found at Shaw Warm Springs which is a relatively unused spring located approximately 6 miles (9.66 km) north of Del Norte, Colorado. The waters at Shaws Warm Spring have a temperature of 86 F (30 C), a discharge of 40 gallons per minute and contain approximately 408 mg/l of total dissolved solids. The assessment program carried out din the western San Luis Valley consisted of: soil mercury geochemical surveys; geothermal gradient drilling; and dipole-dipole electrical resistivity traverses, Schlumberger soundings, Audio-magnetotelluric surveys, telluric surveys, and time-domain electro-magnetic soundings and seismic surveys. Shaw Warm Springs appears to be the only source of thermal waters along the western side of the Valley. From the various investigations conducted the springs appear to be fault controlled and is very limited in extent. Based on best evidence presently available estimates are presented on the size and extent of Shaw Warm Springs thermal system. It is estimated that this could have an areal extent of 0.63 sq. miles (1.62 sq. km) and contain 0.0148 Q's of heat energy.

  7. Global alliance against chronic respiratory diseases in Italy (GARD-Italy): strategy and activities. (United States)

    Laurendi, Giovanna; Mele, Sonia; Centanni, Stefano; Donner, Claudio F; Falcone, Franco; Frateiacci, Sandra; Lazzeri, Marta; Mangiacavallo, Antonino; Indinnimeo, Luciana; Viegi, Giovanni; Pisanti, Paola; Filippetti, Giuseppe


    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.

  8. The Expanded Owens Valley Solar Array (United States)

    Gary, Dale E.; Hurford, G. J.; Nita, G. M.; White, S. M.; Tun, S. D.; Fleishman, G. D.; McTiernan, J. M.


    The Expanded Owens Valley Solar Array (EOVSA) is now under construction near Big Pine, CA as a solar-dedicated microwave imaging array operating in the frequency range 1-18 GHz. The solar science to be addressed focuses on the 3D structure of the solar corona (magnetic field, temperature and density), on the sudden release of energy and subsequent particle acceleration, transport and heating, and on space weather phenomena. The project will support the scientific community by providing open data access and software tools for analysis of the data, to exploit synergies with on-going solar research in other wavelengths. The New Jersey Institute of Technology (NJIT) is expanding OVSA from its previous complement of 7 antennas to a total of 15 by adding 8 new antennas, and will reinvest in the existing infrastructure by replacing the existing control systems, signal transmission, and signal processing with modern, far more capable and reliable systems based on new technology developed for the Frequency Agile Solar Radiotelescope (FASR). The project will be completed in time to provide solar-dedicated observations during the upcoming solar maximum in 2013 and beyond. We provide an update on current status and our preparations for exploiting the data through modeling and data analysis tools. This research is supported by NSF grants AST-0908344, and AGS-0961867 and NASA grant NNX10AF27G to New Jersey Institute of Technology.

  9. Calibrating Treasure Valley Groundwater Model using MODFLOW (United States)

    Hernandez, J.; Tan, K.


    In Idaho, groundwater plays an especially important role in the state. According to the Idaho Department of Environmental Quality, groundwater supplies 95% of the state's drinking water (2011). The USGS estimates that Idaho withdraws 117 million cubic meters (95,000 acre-feet) per year from groundwater sources for domestic usage which includes drinking water. The same report from the USGS also estimates that Idaho withdraws 5,140 million cubic meters (4,170,000 acre-feet) per year from groundwater sources for irrigation usage. Quantifying and managing that resource and estimating groundwater levels in the future is important for a variety of socio-economic reasons. As the population within the Treasure Valley continues to grow, the demand of clean usable groundwater increases. The objective of this study was to develop and calibrate a groundwater model with the purpose of understanding short- and long-term effects of existing and alternative land use scenarios on groundwater changes. Hydrologic simulations were done using the MODFLOW-2000 model. The model was calibrated for predevelopment period by reproducing and comparing groundwater levels of the years before 1925 using steady state boundary conditions representing no change in the land use. Depending on the reliability of the groundwater source, the economic growth of the area can be constrained or allowed to flourish. Mismanagement of the groundwater source can impact its sustainability, quality and could hamper development by increasing operation and maintenance costs. Proper water management is critical because groundwater is such a limited resource.

  10. Fungal Biodiversity in the Alpine Tarfala Valley. (United States)

    Coleine, Claudia; Selbmann, Laura; Ventura, Stefano; D'Acqui, Luigi Paolo; Onofri, Silvano; Zucconi, Laura


    Biological soil crusts (BSCs) are distributed worldwide in all semiarid and arid lands, where they play a determinant role in element cycling and soil development. Although much work has concentrated on BSC microbial communities, free-living fungi have been hitherto largely overlooked. The aim of this study was to examine the fungal biodiversity, by cultural-dependent and cultural-independent approaches, in thirteen samples of Arctic BSCs collected at different sites in the Alpine Tarfala Valley, located on the slopes of Kebnekaise, the highest mountain in northern Scandinavia. Isolated fungi were identified by both microscopic observation and molecular approaches. Data revealed that the fungal assemblage composition was homogeneous among the BSCs analyzed, with low biodiversity and the presence of a few dominant species; the majority of fungi isolated belonged to the Ascomycota, and Cryptococcus gilvescens and Pezoloma ericae were the most frequently-recorded species. Ecological considerations for the species involved and the implication of our findings for future fungal research in BSCs are put forward.

  12. Tennessee Valley Region: a year 2000 profile

    Energy Technology Data Exchange (ETDEWEB)



    A study was undertaken to determine the potential radiological implications of nuclear facilities in the combined watersheds of the Tennessee and Cumberland rivers, an area covering portions of 7 states of varied topography. The regional population in 1970 was about 4.6 million and is expected to increase to about 7 million by the year 2000. A 1973 projection estimated the installed electric generating capacity of the region to increase from a 1970 value of 45,000 megawatts to a total of 222,000 megawatts by the year 2000. In that year, about 144,000 megawatts were projected to be nuclear plants. The profile of the Tennessee Valley Region in the year 2000, as drawn from this report, contains the essential data for calculation of the radiological dose from operation of nuclear facilities in that year. Those calculations are reported in the companion document, DOE/ET-0064/2. Specifically, Volume I establishes the parameters describing where the people live, what they eat, the activities in which they engage, and the environmental surroundings that enable an evaluation of the potential radiation dose to the population. Airborne radionuclides from nuclear facilities in this zone may enter the study area and be deposited on the ground, on growing food, and on water surfaces. Consideration was not given to waterborne radionuclides external to the study region. 17 references. (MCW)

  13. Soil formation in the Tsauchab Valley, Namibia (United States)

    Eden, Marie; Bens, Oliver; Ramisch, Arne; Schwindt, Daniel; Völkel, Jörg


    The BMBF-funded project GeoArchives (Spaces) investigates soils and sediments in Southern Africa. A focus area lies on the Tsauchab Valley (Namibia), South of the Naukluft mountain range (24°26'40'' S, 16°10'40'' E). On a gently sloping alluvial fan facing East towards the river, the surface is characterized by a desert pavement covering soils used as farmland. The landscape units were mapped and the area at the lower slope of a hill was divided into three units: a rinsing surface and a gravel plain, separated by a channel. On these surfaces soil profiles were excavated. Profile description followed the German system (Bodenkundliche Kartieranleitung KA 5) and disturbed samples were taken at various depths and analysed in the lab. Undisturbed soil cores with a volume of 100 cm³ were taken just below the surface at a depth of ~1-6 cm. Lab analyses included texture and gravel content, colour, pH, electrical conductivity, carbonates, CNS, cation exchange capacity, pedogenic oxides, main and trace elements (XRF), and clay mineral distribution (XRD). Undisturbed samples were used to determine soil water retention curve, air permeability and bulk density. The profiles revealed moderately developed cambic soils rich in clay minerals and with total carbon contents ranging up to 1.8 %, bearing shrubs and after episodic rainfall a dense grass vegetation. Their genesis is discussed and interpreted in the context of the landscape and climate history of this semi-desert environment.

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

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

  15. The first book museums in Italy

    Directory of Open Access Journals (Sweden)

    Andrea De Pasquale


    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.

    the coring site. The definition of the source area of these two major events is still a matter of debate. However, the Somma-Vesuvius complex reasonably sourced the Schiava deposits while a Campi Flegrei provenance for the Codola deposits cannot be ruled out (Di Vito et al., 2008). These latters, known as C10 tephra in the Tyrrhenian and Adriatic sea (Paterne et al., 1988; Giaccio et al., 2008), in particular, represent reliable regional markers for the whole central Mediterranean area.

    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.

  18. Actinides AMS at CIRCE in Caserta (Italy) (United States)

    De Cesare, M.; Gialanella, L.; Rogalla, D.; Petraglia, A.; Guan, Y.; De Cesare, N.; D'Onofrio, A.; Quinto, F.; Roca, V.; Sabbarese, C.; Terrasi, F.


    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.

  19. Underestimation of Invasive Meningococcal Disease in Italy. (United States)

    Azzari, Chiara; Nieddu, Francesco; Moriondo, Maria; Indolfi, Giuseppe; Canessa, Clementina; Ricci, Silvia; Bianchi, Leila; Serranti, Daniele; Poggi, Giovanni Maria; Resti, Massimo


    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

  1. Shipbuilding and mesothelioma in Monfalcone, Italy. (United States)

    Bianchi, Claudio; Bianchi, Tommaso


    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.

  2. Ionospheric precursors for crustal earthquakes in Italy

    Directory of Open Access Journals (Sweden)

    L. Perrone


    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.

  3. [The management of foreign workers in Italy]. (United States)

    Iavicoli, Sergio; Valenti, Antonio; Persechino, Benedetta


    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.

  5. A tectonomagnetic effect detected in Central Italy

    Directory of Open Access Journals (Sweden)

    P. Palangio


    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.

  6. The Role of Source Material in Basin Sedimentation, as Illustrated within Eureka Valley, Death Valley National Park, CA. (United States)

    Lawson, M. J.; Yin, A.; Rhodes, E. J.


    Steep landscapes are known to provide sediment to sink regions, but often petrological factors can dominate basin sedimentation. Within Eureka Valley, in northwestern Death Valley National Park, normal faulting has exposed a steep cliff face on the western margin of the Last Chance range with four kilometers of vertical relief from the valley floor and an angle of repose of nearly 38 degrees. The cliff face is composed of Cambrian limestone and dolomite, including the Bonanza King, Carrara and Wood Canyon formations. Interacting with local normal faulting, these units preferentially break off the cliff face in coherent blocks, which result in landslide deposits rather than as finer grained material found within the basin. The valley is well known for a large sand dune, which derives its sediment from distal sources to the north, instead of from the adjacent Last Chance Range cliff face. During the Holocene, sediment is sourced primary from the northerly Willow Wash and Cucomungo canyon, a relatively small drainage (less than 80 km2) within the Sylvan Mountains. Within this drainage, the Jurassic quartz monzonite of Beer Creek is heavily fractured due to motion of the Fish Valley Lake - Death Valley fault zone. Thus, the quartz monzonite is more easily eroded than the well-consolidated limestone and dolomite that forms the Last Change Range cliff face. As well, the resultant eroded material is smaller grained, and thus more easily transported than the limestone. Consequently, this work highlights an excellent example of the strong influence that source material can have on basin sedimentation.

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

    Directory of Open Access Journals (Sweden)

    M. T. Brunetti


    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

  8. Agricultural Development, Land Change, and Livelihoods in Tanzania's Kilombero Valley (United States)

    Connors, John Patrick

    The Kilombero Valley lies at the intersection of a network of protected areas that cross Tanzania. The wetlands and woodlands of the Valley, as well as the forest of surrounding mountains are abundant in biodiversity and are considered to be critical areas for conservation. This area, however, is also the home to more than a half million people, primarily poor smallholder farmers. In an effort to support the livelihoods and food security of these farmers and the larger Tanzanian population, the country has recently targeted a series of programs to increase agricultural production in the Kilombero Valley and elsewhere in the country. Bridging concepts and methods from land change science, political ecology, and sustainable livelihoods, I present an integrated assessment of the linkages between development and conservation efforts in the Kilombero Valley and the implications for food security. This dissertation uses three empirical studies to understand the process of development in the Kilombero Valley and to link the priorities and perceptions of conservation and development efforts to the material outcomes in food security and land change. The first paper of this dissertation examines the changes in land use in the Kilombero Valley between 1997 and 2014 following the privatization of agriculture and the expansion of Tanzania's Kilimo Kwanza program. Remote sensing analysis reveals a two-fold increase in agricultural area during this short time, largely at the expense of forest. Protected areas in some parts of the Valley appear to be deterring deforestation, but rapid agricultural growth, particularly surrounding a commercial rice plantation, has led to loss of extant forest and sustained habitat fragmentation. The second paper focuses examines livelihood strategies in the Valley and claims regarding the role of agrobiodiversity in food security. The results of household survey reveal no difference or lower food security among households that diversify their

    Full Text Available Background: Lung cancer has been found to be the second commonest cancer according to a hospital-based data from Kashmir, India. However, no incidence studies are available. Objective: To ascertain the incidence of lung cancer in Kashmir. Materials and Methods: All newly histologically diagnosed cases of lung cancer seen in various hospital and private laboratories of the Kashmir valley were registered over a period of two years (January 1, 2004 to December 31, 2005. Also included were patients attending the various oncological service areas of the institute and those diagnosed from any other laboratory outside the state. The incidence rate was calculated using the January 2005 population as the reference population estimated using the census-based projected populations. Results: Four hundred and sixty-two incident cases of lung cancer were seen during the study period. The crude incidence rate, age standardized (world and truncated age adjusted (40-69 years, world incidence rates for lung cancer per 100 000 population were 4.01, 6.48 and 15.28 respectively (males 6.55, 10.09 and 23.94 respectively and females 1.19, 2.14 and 4.65. The age adjusted rates for males in district Srinagar was 19.34 per 100 000. One hundred and fifty nine (69.8% of the 221 had a history of Hukkah smoking. Conclusions: Even though Kashmir as a whole is a low incidence area for lung cancer (ASR of < 15, Srinagar district has the highest incidence of lung cancer among the males in Kashmir. The data presented is assumed to be the closest approximation to a population-based data registry and the geographical incidence maps of ICMR need appropriate updating

  10. The Evaporation Valley in the Kepler Planets (United States)

    Owen, James E.; Wu, Yanqin


    A new piece of evidence supporting the photoevaporation-driven evolution model for low-mass, close-in exoplanets was recently presented by the California-Kepler Survey. The radius distribution of the Kepler planets is shown to be bimodal, with a “valley” separating two peaks at 1.3 and 2.6 R ⊕. Such an “evaporation valley” had been predicted by numerical models previously. Here, we develop a minimal model to demonstrate that this valley results from the following fact: the timescale for envelope erosion is the longest for those planets with hydrogen/helium-rich envelopes that, while only a few percent in weight, double its radius. The timescale falls for envelopes lighter than this because the planet’s radius remains largely constant for tenuous envelopes. The timescale also drops for heavier envelopes because the planet swells up faster than the addition of envelope mass. Photoevaporation therefore herds planets into either bare cores (˜1.3 R ⊕), or those with double the core’s radius (˜2.6 R ⊕). This process mostly occurs during the first 100 Myr when the stars’ high-energy fluxes are high and nearly constant. The observed radius distribution further requires the Kepler planets to be clustered around 3 M ⊕ in mass, born with H/He envelopes more than a few percent in mass, and that their cores are similar to the Earth in composition. Such envelopes must have been accreted before the dispersal of the gas disks, while the core composition indicates formation inside the ice line. Lastly, the photoevaporation model fails to account for bare planets beyond ˜30-60 days; if these planets are abundant, they may point to a significant second channel for planet formation, resembling the solar system terrestrial planets.

  11. Second-hand smoke in Italy. (United States)

    Gallus, S


    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

  12. The Ml Magnitude Scale In Italy (United States)

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

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

  13. Adaptively smoothed seismicity earthquake forecasts for Italy

    Directory of Open Access Journals (Sweden)

    Yan Y. Kagan


    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.

  14. Molecular epidemiology of Usher syndrome in Italy (United States)

    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.

  16. Global change and river flow in Italy (United States)

    Billi, Paolo; Fazzini, Massimiliano


    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.

  17. Moral Foundations and Voting Intention in Italy. (United States)

    Milesi, Patrizia


    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

  19. A socioeconomic profile of vulnerable land to desertification in Italy. (United States)

    Salvati, Luca


    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.

  20. The Strategic Plan for Tourism Development in Italy

    Directory of Open Access Journals (Sweden)

    Silvia ANGELONI


    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.

  1. West Valley facility spent fuel handling, storage, and shipping experience

    Energy Technology Data Exchange (ETDEWEB)

    Bailey, W.J.


    The result of a study on handling and shipping experience with spent fuel are described in this report. The study was performed by Pacific Northwest Laboratory (PNL) and was jointly sponsored by the US Department of Energy (DOE) and the Electric Power Research Institute (EPRI). The purpose of the study was to document the experience with handling and shipping of relatively old light-water reactor (LWR) fuel that has been in pool storage at the West Valley facility, which is at the Western New York Nuclear Service Center at West Valley, New York and operated by DOE. A subject of particular interest in the study was the behavior of corrosion product deposits (i.e., crud) deposits on spent LWR fuel after long-term pool storage; some evidence of crud loosening has been observed with fuel that was stored for extended periods at the West Valley facility and at other sites. Conclusions associated with the experience to date with old spent fuel that has been stored at the West Valley facility are presented. The conclusions are drawn from these subject areas: a general overview of the West Valley experience, handling of spent fuel, storing of spent fuel, rod consolidation, shipping of spent fuel, crud loosening, and visual inspection. A list of recommendations is provided. 61 refs., 4 figs., 5 tabs.

  2. Effects of valley meteorology on forest pesticide spraying

    Energy Technology Data Exchange (ETDEWEB)

    Whiteman, C.D.


    Pacific Northwest Laboratory conducted this study for the Missoula Technology and Development Center of the US Department of Agriculture's Forest Service. The purpose of the study was to summarize recent research on valley meteorology during the morning transition period and to qualitatively evaluate the effects of the evolution of valley temperature inversions and wind systems on the aerial spraying of pesticides in National Forest areas of the western United States. Aerial spraying of pesticides and herbicides in forests of the western United States is usually accomplished in the morning hour after first light, during the period known to meteorologists as the morning transition period.'' This document describes the key physical processes that occur during the morning transition period on undisturbed days and the qualitative effects of these processes on the conduct of aerial spraying operations. Since the timing of valley meteorological events may be strongly influenced by conditions that are external to the valley, such as strong upper-level winds or the influence of clouds on the receipt of solar energy in the valley, some remarks are made on the qualitative influence of these processes. Section 4 of this report suggests ways to quantify some of the physical processes to provide useful guidance for the planning and conduct of spraying operations. 12 refs., 9 figs.

    Full Text Available Extreme meteorological events such as heavy rainstorms are considered to increase due to global warming. The consequences of such events can be manifold, and might cause massive interferences of the hydrological system of a landscape. Particularly the intramontane basins of the Apennine in Italy are frequently threatened by extreme rainfall events that cause severe damage on buildings and infrastructure. Moreover, the lithological and geomorphological settings of these basins, which depict the products of a complex landscape history, amplify these threats. In order to develop possible mitigation strategies, it is crucial to assess landscape functioning by analysing hydrological processes of the landscape system. In this study, we conducted spatially distributed and dynamic hydrological modelling on a catchment in the intramontane basin of the Mugello valley in Tuscany, Italy. Foremost, measurements of saturated hydraulic conductivity and texture analyses were performed to estimate both infiltration and hydraulic conductivity of the surface and topsoil, respectively. We regionalised the collected data with a stochastic gradient treeboost method for the whole catchment. Soil depth was estimated with a simple sine-cosine-slope relation, whereas, hydropedologic parameters for the hydrological model were estimated with pedotransferfunctions applied on the collected infiltration data. We modelled a period of 100 days, representing each day per time step. A synthetic rainfall period was compiled based on measured data from meteorological stations within the Mugello basin. To produce a reliable synthetic rainfall data set, the estimated precipitation values were set in comparison to calculated return periods for extreme events of all available meteorological station. To assess the diversity of the hydrological response of several locations in the catchment, six semirandom test locations were located on hillslopes and spots were sedimentation is apparent

  4. Multidisciplinary investigations on the Roman aqueduct of Grumentum (Basilicata, Southern Italy

    Directory of Open Access Journals (Sweden)

    M. Mucciarelli


    Full Text Available The Romans built the ancient town of Grumentum during the 3rd century B.C. in the southern part of the Agri high Valley (Basilicata Region, Southern Italy near the confluence of the Sciaura stream in the Agri River. Now it is one of the most important archaeological sites of Southern Italy. In fact, after a period of wars in this area between Romans and Carthaginians, a great deal of restoration was started in 57 B.C. These works affected the city walls, public buildings and finally endowed the Roman colony with important infrastructures, such as the new aqueduct. In this work, we attempt to reconstruct the ancient layout of the Roman aqueduct of Grumentum. As a starting point, we followed some descriptions from the 19th century, when the structure was still well preserved. Then, we performed a multidisciplinary geophysical approach to the best preserved remains of the aqueduct. In particular, the geophysical investigation started with the use of a portable GPS allowing us to acquire the co-ordinates of the outcropping rests of the ancient structure. Then, we used an optical pumping magnetometer to perform seven gradiometric maps over a broad area of about 8000 m2. From the literature descriptions, dating to the first part of the 19th century, we can deduce that the state of preservation of the Roman aqueduct was much better than the present one. Thus we can hypothesise as the cause of its fast involution the fact that it was located in the epicentral area of the large destructive earthquake which occurred in the Basilicata Region in 1857 (Mallet, 1862. To this aim, we performed a first attempt to correlate the state of preservation of the aqueduct remains with the local seismic amplification by means of the HVSR (Horizontal to Vertical Spectral Ratio technique. This survey allowed us to obtain the site amplification spectra along the aqueduct layout and assess the fundamental vibration frequency of the investigated structure

  7. Preliminary hydrogeologic assessment near the boundary of the Antelope Valley and El Mirage Valley groundwater basins, California (United States)

    Stamos, Christina L.; Christensen, Allen H.; Langenheim, Victoria


    The increasing demands on groundwater for water supply in desert areas in California and the western United States have resulted in the need to better understand groundwater sources, availability, and sustainability. This is true for a 650-square-mile area that encompasses the Antelope Valley, El Mirage Valley, and Upper Mojave River Valley groundwater basins, about 50 miles northeast of Los Angeles, California, in the western part of the Mojave Desert. These basins have been adjudicated to ensure that groundwater rights are allocated according to legal judgments. In an effort to assess if the boundary between the Antelope Valley and El Mirage Valley groundwater basins could be better defined, the U.S. Geological Survey began a cooperative study in 2014 with the Mojave Water Agency to better understand the hydrogeology in the area and investigate potential controls on groundwater flow and availability, including basement topography.Recharge is sporadic and primarily from small ephemeral washes and streams that originate in the San Gabriel Mountains to the south; estimates range from about 400 to 1,940 acre-feet per year. Lateral underflow from adjacent basins has been considered minor in previous studies; underflow from the Antelope Valley to the El Mirage Valley groundwater basin has been estimated to be between 100 and 1,900 acre-feet per year. Groundwater discharge is primarily from pumping, mostly by municipal supply wells. Between October 2013 and September 2014, the municipal pumpage in the Antelope Valley and El Mirage Valley groundwater basins was reported to be about 800 and 2,080 acre-feet, respectively.This study was motivated by the results from a previously completed regional gravity study, which suggested a northeast-trending subsurface basement ridge and saddle approximately 3.5 miles west of the boundary between the Antelope Valley and El Mirage Valley groundwater basins that might influence groundwater flow.

    R. Coletto


    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.

  10. Perceptual discrimination difficulty and familiarity in the Uncanny Valley: more like a "Happy Valley". (United States)

    Cheetham, Marcus; Suter, Pascal; Jancke, Lutz


    The Uncanny Valley Hypothesis (UVH) predicts that greater difficulty perceptually discriminating between categorically ambiguous human and humanlike characters (e.g., highly realistic robot) evokes negatively valenced (i.e., uncanny) affect. An ABX perceptual discrimination task and signal detection analysis was used to examine the profile of perceptual discrimination (PD) difficulty along the UVH' dimension of human likeness (DHL). This was represented using avatar-to-human morph continua. Rejecting the implicitly assumed profile of PD difficulty underlying the UVH' prediction, Experiment 1 showed that PD difficulty was reduced for categorically ambiguous faces but, notably, enhanced for human faces. Rejecting the UVH' predicted relationship between PD difficulty and negative affect (assessed in terms of the UVH' familiarity dimension), Experiment 2 demonstrated that greater PD difficulty correlates with more positively valenced affect. Critically, this effect was strongest for the ambiguous faces, suggesting a correlative relationship between PD difficulty and feelings of familiarity more consistent with the metaphor happy valley. This relationship is also consistent with a fluency amplification instead of the hitherto proposed hedonic fluency account of affect along the DHL. Experiment 3 found no evidence that the asymmetry in the profile of PD along the DHL is attributable to a differential processing bias (cf. other-race effect), i.e., processing avatars at a category level but human faces at an individual level. In conclusion, the present data for static faces show clear effects that, however, strongly challenge the UVH' implicitly assumed profile of PD difficulty along the DHL and the predicted relationship between this and feelings of familiarity.

  12. Rivers and valleys of Pennsylvania, revisited (United States)

    Morisawa, Marie


    The 1889 paper by William Morris Davis on the "Rivers and Valleys of Pennsylvania" is a landmark in the history of geomorphology. It was in this manuscript that he set forth what came to be known as the Davisian system of landscape. It is important to understand that Davis' interpretation of landforms was restricted by the geologic paradigms of his day. Uniformitarianism was strongly entrenched and Darwin's theory of evolution had become popularly accepted. The concept of the landmass Appalachia and then current theories on mountain building affected the approach that Davis took in hypothesizing the origin and development of the Folded Appalachian drainage. All of these geologic precepts influenced the formulation and explanation of his theories. In his exposition he adapted, synthesized and embellished on ideas he derived from fellow geologists such as Gilbert, Dutton, Powell, and McGee. A number of the concepts he proposed in the 1889 paper quickly became the bases for geomorphic studies by others: the cycles of river erosion and landscape evolution and the peneplain (here called base level erosion). The cycle of erosion became the model for subsequent geomorphic analyses, and peneplain hunting became a popular sport for geomorphologists. Davis' hypothesis of the origin and development of Pennsylvanian drainage stimulated subsequent discussion and further hypotheses by others. In fact, many of the later theories were refinements and/or elaborations of ideas mentioned in this paper of Davis. He proposed the origin of the drainage as consequent streams, then antecedence, superposition, headward extension of divides by piracy, erosion along lines of weaknesses (faults, easily erodible beds) through resistant ridges and normal fluvial erosion. Thus, the hypotheses of regional superposition (Johnson), extended consequents (Ruedemann), consequents and local superposition (Meyerhoff and Olmstead), the utilization of structural weaknesses in development of transverse

  13. Surface Deformation in Imperial Valley, Southern California (United States)

    Eneva, M.; Adams, D.; Falorni, G.; Morgan, J.


    The Imperial Valley in southern California is subjected to significant tectonic deformation resulting from the relative movement of the North American and Pacific plates. It is characterized by large earthquakes, frequent swarm activity, and aseismic events. High heat flow makes possible the operation of geothermal fields, some of which cause man-made surface displacements superimposed on the tectonic deformation. We apply radar interferometry (InSAR) to analyze Envisat ASAR data for the period 2003-2010. The SqueeSAR technique is used to obtain deformation time series and annual rates at numerous locations of permanent and distributed scatterers (PS and DS). SqueeSAR works very well in agricultural areas, where conventional differential InSAR (DinSAR) fails. We observe differential movements marking the Superstition Hills, San Andreas, and Imperial faults. The Imperial fault traverses agricultural fields, where DInSAR does not work and thus our SqueeSAR observations are the first for this fault (Fig. 1). We also observe steps in the deformation time series around the Superstition Hills fault from an October 2006 aseismic event and the April 2010 M7.2 earthquake south of the U.S.-Mexico border. Significant annual deformation rates are detected in the current geothermal fields. For example, subsidence of up to -50 mm/year is seen at the Salton Sea field (Fig. 2), and both subsidence and uplift are seen at Heber. We also determine the deformation baseline at prospective geothermal fields, thus making it possible in the future to distinguish between man-made and tectonic causes of surface deformation. Fig. 1. Line-of-sight (LOS) deformation indicates differential displacement on both sides of Imperial Fault. Movements away from the satellite are shown in yellow to red, and towards the satellite in blue. Larger deformation is associated with two geothermal fields, Heber (to the south-west) and East Mesa (to the east). Fig. 2. Subsidence in the Salton Sea geothermal

  14. Origins and global context of Brucella abortus in Italy. (United States)

    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

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

    Energy Technology Data Exchange (ETDEWEB)



    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.

  17. Technical Analysis of In-Valley Drainage Management Strategies for the Western San Joaquin Valley, California (United States)

    Presser, Theresa S.; Schwarzbach, Steven E.


    The western San Joaquin Valley is one of the most productive farming areas in the United States, but salt-buildup in soils and shallow groundwater aquifers threatens this area?s productivity. Elevated selenium concentrations in soils and groundwater complicate drainage management and salt disposal. In this document, we evaluate constraints on drainage management and implications of various approaches to management considered in: *the San Luis Drainage Feature Re-Evaluation (SLDFRE) Environmental Impact Statement (EIS) (about 5,000 pages of documentation, including supporting technical reports and appendices); *recent conceptual plans put forward by the San Luis Unit (SLU) contractors (i.e., the SLU Plans) (about 6 pages of documentation); *approaches recommended by the San Joaquin Valley Drainage Program (SJVDP) (1990a); and *other U.S. Geological Survey (USGS) models and analysis relevant to the western San Joaquin Valley. The alternatives developed in the SLDFRE EIS and other recently proposed drainage plans (refer to appendix A for details) differ from the strategies proposed by the San Joaquin Valley Drainage Program (1990a). The Bureau of Reclamation (USBR) in March 2007 signed a record of decision for an in-valley disposal option that would retire 194,000 acres of land, build 1,900 acres of evaporation ponds, and develop a treatment system to remove salt and selenium from drainwater. The recently proposed SLU Plans emphasize pumping drainage to the surface, storing approximately 33% in agricultural water re-use areas, treating selenium through biotechnology, enhancing the evaporation of water to concentrate salt, and identifying ultimate storage facilities for the remaining approximately 67% of waste selenium and salt. The treatment sequence of reuse, reverse osmosis, selenium bio-treatment, and enhanced solar evaporation is unprecedented and untested at the scale needed to meet plan requirements. All drainage management strategies that have been proposed

  18. Reflection Seismic Imaging of Buried Valleys, Onshore Denmark (United States)

    Lykke-Andersen, H.; Jørgensen, F.; Nørmark, E.

    The steadily increasing demands for securing supplies of clean groundwater have in recent years led to the adoption of reflection seismics in the family of geophysical methods used for groundwater research in Denmark. Buried valleys- often some km wide and a few hundred metres deep - have proved to be important sites for deeply seated, well protected groundwater reservoirs. It is a well known fact that the structure of buried valleys is complicated. With their potential for generation of relatively high resolution images of depositional and tectonic structures, reflection seismics have be- come a valuable supplement to the traditional resistivity methods in the study of buried valleys. Reflection seismic is an expensive method compared to other methods in use for groundwater research; therefore, careful selection of profile locations is mandatory. A practice has developed where selection of locations are based on mapping results obtained by resistivity methods. Results obtained by dynamite and vibrator sources are presented. Experience shows that the quality of the two data types is comparable. Vertical resolution better than ca. 10 m can be obtained, but the bandwidth of data is variable. In areas where non-(water) saturated shallow sediments are present; the bandwidth may be strongly reduced. Depth penetration down to at least one km is normally obtained. The seismic data are tied to wells by means of vertical seismic profiles in exploratory wells. Results are presented to illustrate: 1) potentials and limi- tations of the method and 2) a number of valleys with different types of valley-fill and relationships with the substratum. The genesis of the valleys will be briefly discussed.

  12. Giant and tunable valley degeneracy splitting in MoTe2 (United States)

    Li, Xiao; Qi, Jingshan; Niu, Qian; Feng, Ji

    Valleys in monolayer transition-metal dichalcogenides seamlessly connect two basic carriers of quantum information, namely, the electron spin and photon helicity. Lifting the valley degeneracy is an attractive route to achieve further optoelectronic manipulations. However, the magnetic field only creates a very small valley splitting. We propose a strategy to create giant valley splitting by the proximity-induced Zeeman effect. Our first principles calculations of monolayer MoTe2 on a EuO substrate show that valley splitting over 300 meV can be generated. Interband transition energies become valley dependent, leading to selective spin-photon coupling by optical frequency tuning. The valley splitting is also continuously tunable by rotating the substrate magnetization. The giant and tunable valley splitting adds a different dimension to the exploration of unique optoelectronic devices based on magneto-optical coupling and magnetoelectric coupling.

    Barzon, Luisa; Pacenti, Monia; Franchin, Elisa; Squarzon, Laura; Lavezzo, Enrico; Cattai, Margherita; Cusinato, Riccardo; Palù, Giorgio


    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

    Directory of Open Access Journals (Sweden)

    Giulia Ferrari


    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.

  20. Hydrogeology of the carbonate rocks of the Lebanon Valley, Pennsylvania (United States)

    Meisler, Harold


    The Lebanon Valley, which is part of the Great Valley in southeastern Pennsylvania, is underlain by carbonate rocks in the southern part and by shale in the northern part. The carbonate rocks consist of alternating beds of limestone and dolomite of Cambrian and Ordovician age. Although the beds generally dip to the south, progressively younger beds crop out to the north, because the rocks are overturned. The stratigraphic units, from oldest to youngest, are: the Buffalo Springs Formation, Snitz Creek, Schaefferstown, Millbach, and Richland Formations of the Conococheague Group; the Stonehenge, Rickenbach, Epler, and Ontelaunee Formations of the Beekmantown Group; and the Annville, Myerstown, and Hershey Limestones.
