An interdisciplinary approach is proposed to investigate the structure and composition of the Permo-Triassic basement of the Hyblean Plateau and Sicily Channel. Comparisons of published data on peridotites and spinels from different geodynamic settings, and new data on Hyblean spinels, reveal the affinity of the Hyblean basement with an ultra-slow spreading oceanic lithosphere, rather than with the Africa continental plate. Similar results derive from volcanic rocks of the studied area, whose Nb/Yb vs. Th/Yb ratio hints at their affinity with the MORB-OIB array, even excluding any possible contamination with continental crust lithologies, unlike North Africa lavas. The comparison of He isotopic ratios from Hyblean Plateau and Sicily Channel highlights their similarity with values measured in fluids emitted from the Rainbow and Logatchev hydrothermal fields in Mid-Atlantic Ridge. Based on petrologic and geochemical evidence for the oceanic nature of the Permo-Triassic basement in southeastern Sicily, and the occurrence of serpentinized harzburgite xenoliths in Hyblean diatremes, the P-wave velocity model proposed for the investigated area is used to estimate lithospheric pressure, density, degree of serpentinization and magnetic susceptibility also considering both abyssal and ophiolitic serpentinites. The resulting values suggest the presence of peridotites affected by different degrees of serpentinization (35-100 vol.%) ranging to a depth of 8-19 km. As a whole, combined seismic, gravimetric and magnetic data indicate the presence of a marked anomaly at a depth of about 19 km. As a consequence, we consider the Moho discontinuity as a serpentinization front, by fixing the relative top at a depth of 19 km. Our results suggest that the oceanic lithospheric model for southeastern Sicily could be broadened to the Sicily Channel, which is possibly correlated to the adjacent Ionian oceanic basin, inferred as belonging to the Oman-Iraq-Levantine-Sicily seaway.

Full Text Available Mediterranean spotted fever (MSF is endemic in Italy, where Rickettsia conorii subsp. conorii was thought to be the only pathogenic rickettsia and Rhipicephalus sanguineus the vector and main reservoir. R. conorii subsp. israelensis, which belongs to the R. conorii complex, is the agent of Israeli spotted fever (ISF; apart from Israel, it has also been found in Italy (Sicily and Sardinia and in different regions of Portugal. We describe here two severe cases of ISF which occurred in otherwise healthy Italian adults. Their characteristics are analyzed and discussed in the light of other 91 cases found through a systematic review of international literature.

The study of the source of 1693 tsunami in eastern Sicily (South Italy) is still debated in the scientific community. Macroseismic analyses provide inland location for the epicenter of the earthquake, while historical reports describing 1-2 m waves hitting the coast suggest the existence of at least an offshore extension of the fault. Furthermore, an anomalous water elevation was described in Augusta (between Siracusa and Catania), that was interpreted as the manifestation of a local submarine landslide. The presence of the steep Hyblaean-Malta escarpment, that runs parallel to the eastern coast of Sicily at a short distance from the shoreline and is cut by several canyons and scars, corroborates the hypothesis of a landslide occurrence, though no clear evidence has been found yet. This research, realized in the frame of the project ASTARTE (Assessment, Strategy And Risk Reduction for Tsunamis in Europe - FP7-ENV2013 6.4-3, Grant 603839), aims at assessing the effect of landslide-generated tsunamis on the coastal stretch around Augusta considering different scenarios of collapsing masses along the Hyblaean-Malta escarpment. The slide dynamics is computed by means of the numerical code UBO-BLOCK1 (developed by the University of Bologna Tsunami Research Team), and the corresponding tsunami is simulated via the code UBO-TSUFD. The sliding bodies are placed in different positions in order to assess which of them could produce significant effects on the town of Augusta, providing then clues on the possible source area for the hypothesized slide related to the 1693 tsunami. The sensitivity analysis shows the spatial dependence of the coastal tsunami height on the source volume, position, distance from the coast, and on other parameters.

Water samples collected from public drinking water supplies in Sicily were analysed for electric conductivity and for their chloride, sulphate and nitrate contents. The samples were collected as uniformly as possible from throughout the Sicilian territory, with an average sampling density of about one sample for every 7,600 inhabitants. Chloride contents that ranged from 5.53 to 1,302 mg/l were correlated strongly with electric conductivity, a parameter used as a proxy for water salinity. The highest values are attributable to seawater contamination along the coasts of the island. High chloride and sulphate values attributable to evaporitic rock dissolution were found in the central part of Sicily. The nitrate concentrations ranged from 0.05 to 296 mg/l, with 31 samples (4.7% of the total) exceeding the maximum admissible concentration of 50 mg/l. Anomalous samples always came from areas of intensive agricultural usage, indicating a clear anthropogenic origin. The same parameters were also measured in bottled water sold in Sicily, and they all were within the ranges for public drinking water supplies. The calculated mean nitrate intake from consuming public water supplies (16.1 mg/l) did not differ significantly from that of bottled water (15.2 mg/l). Although the quality of public water supplies needs to be improved by eliminating those that do not comply with the current drinking water limits, at present it does not justify the high consumption of bottled water (at least for nitrate contents).

Behaviour Codes in Sicily. Bypassing the Law

Anton Blok

2010-08-01

Full Text Available Focused on oral culture in western Sicily, this paper explores informal behaviour codes in their interaction with formal law. State-formation in Italy left people in peripheral areas to forge strategies of self-help and negotiate support from patrons (called “friends”. Ironically, the very networks of clientelism and their attendant behaviour codes further weakened the state’s control over its southern periphery and hindered its economic integration into the national and international economy – which in turn reinforced the impact of informal codes and practices on the working of formal law. The Sicilian case provides an example of the periphery as a locus of innovation.

Full Text Available Many destructive shallow landslides hit villages in the Peloritani Mountains area (Sicily, Italy on 1 October 2009 after heavy rainfall. The collection of several types of spatial data, together with a landslide inventory, allows the assessment of the landslide susceptibility by applying a statistical technique. The susceptibility model was validated by performing an analysis in a test area using independent landslide information, the results being able to correctly predict more than 70% of the landslides. Furthermore, the susceptibility analysis allowed the identification of which combinations of classes, within the different factors, have greater relevance in slope instability, and afterwards associating the most unstable combinations (with a short–medium term incidence with the endogenic processes acting in the area (huge regional uplift, fault activity. Geological and tectonic history are believed to be key to interpreting morphological processes and landscape evolution. Recent tectonic activity was found to be a very important controlling factor in landscape evolution. A geomorphological model of cyclical relief evolution is proposed in which endogenic processes are directly linked to superficial processes. The results are relevant both to risk reduction and the understanding of active geological dynamics.

Harmful algal blooms represent a severe issue worldwide. They affect ecosystem functions and related services and goods, with consequences on human health and socio-economic activities. This study reports new data on paralytic shellfish toxins (PSTs) from Sardinia and Sicily (Italy), the largest Mediterranean islands where toxic events, mainly caused by Alexandrium species (Dinophyceae), have been ascertained in mussel farms since the 2000s. The toxicity of the A. minutum, A. tamarense and A. pacificum strains, established from the isolation of vegetative cells and resting cysts, was determined by high performance liquid chromatography (HPLC). The analyses indicated the highest toxicity for A. pacificum strains (total PSTs up to 17.811 fmol cell-1). The PSTs were also assessed in a strain of A. tamarense. The results encourage further investigation to increase the knowledge of toxic species still debated in the Mediterranean. This study also reports new data on microcystins (MCs) and β-N-methylamino-L-alanine (BMAA) from a Sardinian artificial lake (Lake Bidighinzu). The presence of MCs and BMAA was assessed in natural samples and in cell cultures by enzyme-linked immunosorbent assay (ELISA). BMAA positives were found in all the analysed samples with a maximum of 17.84 µg L-1. The obtained results added further information on cyanotoxins in Mediterranean reservoirs, particularly BMAA, which have not yet been thoroughly investigated.

The aim of this study was to evaluate Pb and Cu accumulation in muscle and skin samples of red fox (Vulpes vulpes) from Sicily, for monitoring of environmental metals pollution. Metals determination, carried out by atomic absorption spectrophotometer (AAS), showed the presence of Pb and Cu in all samples analyzed. Pb concentrations were similar in muscle (0.04±0.009 mg/kg) and skin (0.03±0.004 mg/kg) samples, while Cu levels resulted higher in muscle (1.842±0.178 mg/kg) than in skin (1.22±0.151 mg/kg). In addition, a comparative analysis of Pb and Cu concentrations was carried out among samples from different areas of Sicily and between female and male, young and old, immature and mature foxes. Metals content found in all muscle and skin samples demonstrates that V. vulpes could be a valid "sentinel" species of rural and suburban areas to study the environmental metals pollution and the habitat quality.

Tito Aronica, Giuseppe; Bonaccorso, Brunella

2013-04-01

In recent years an increasing attention has been paid to hydropower generation, since it is a renewable, efficient, and reliable source of energy, as well as an effective tool to reduce the atmospheric concentrations of greenhouse gases resulting from human activities. At the same time, however, hydropower is high vulnerable to global warming, because water resources are closely linked to climate changes. Indeed, the effects of climate change on water availability are expected to affect hydropower generation with special reference to Southern countries which are supposed to face dryer conditions in the next decades. The aim of this paper is to assess the impact of future climate change on the hydrological regime of the Alcantara river basin, Eastern Sicily (Italy), based on Monte Carlo simulations. Synthetic series of daily rainfall and temperature are generated, based on observed data, through a first order Markov chain and an ARMA model respectively, for the current scenario and two future scenarios at 2025. In particular, the mean and standard deviation values of daily rainfall and temperature at 2025, calculated using simulations of the Hadley Centre Ocean-Atmosphere General Circulation Model (HadCM3), are adopted to generate future scenarios of precipitation and temperature. Synthetic series for the two climatic scenarios are, then, introduced as input into the IHACRES model to simulate the hydrological response of the basin. The effects of climate change are, then, investigated by analysing potential modification of the resulting flow duration curves and utilisation curves, which allow to estimate a site's energy potential for the design of run-of-river hydropower plants.

In recent years, the preservation of biodiversity has become an important issue. Despite much public discussion, however, current practices in the food industry seldom take account of its potential economic importance: on the contrary, the introduction of industrialized agriculture practices over large areas has often resulted in a dramatic reduction in biodiversity. In this paper, we report on the remarkable degree of biodiversity in the wine yeast populations naturally present in a small area of Sicily (Italy) where traditional (non-industrial) winery practices are still in place. Out of more than 900 Saccharomyces yeast isolates recovered from late spontaneous fermentations, we detected at least 209 strains. Most interestingly, when evaluated at the fermentation and technological level, a number of isolates were found to be superior to industrial yeast strains. Out of a selected group, isolates from two strains were used for experimental fermentations in a winery environment and the quality of the wines produced was assessed at the technological, quality and sensory levels. Given that the characteristics of the wines produced were found to be industrially appealing, the study demonstrated the economic potential of preserving the patrimony of Sicilian yeast biodiversity and highlighted the importance of maintaining traditional wine making practices.

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

The aim of this study was to obtain information on the presence and levels of hazardous organic pollutants in groundwater located close to solid waste landfills. Eighty-two environmental contaminants, including 16 polycyclic aromatic hydrocarbons (PAHs), 20 volatile organic compounds (VOCs), 29 polychlorinated biphenyls (PCBs), 7 dioxins (polychlorinated dibenzo-p-dioxins, PCDDs) and 10 furans (polychlorinated dibenzofurans, PCDFs) were monitored in areas characterised by different geological environments surrounding three municipal solid waste landfills (Palermo, Siculiana and Ragusa) in Sicily (Italy) in three sampling campaigns. The total concentrations of the 16 PAHs were always below the legal threshold. Overall, the Fl/Fl + Py diagnostic ratio revealed that PAHs had a petrogenic origin. VOC levels, except for two notable exceptions near Palermo landfill, were always below the legal limit. As concerns PCB levels, several samples were found positive with levels exceeding the legal limits. It is worth noting that the % PCB distribution differs from that of commercial compositions. In parallel, some samples of groundwater containing PCDDs and PCDFs exceeding the legal threshold were also found. Among the 17 congeners monitored, the most abundant were the highest molecular weight ones.

Climate effects on cork growth in Cork oak plantations in Sicily (Italy

Directory of Open Access Journals (Sweden)

2009-03-01

Full Text Available Cork oak (Quercus suber L. is usually dominant in silvopastoral systems in many areas of Sicily, where the trees are debarked periodically for cork production. In spite of the importance of cork and cork oak stands in Sicilian forests and the potential economic scenarios, few research works have been carried out on these systems. Given the importance of cork thickness in cork quality evaluation, the main objective of this work is to study cork growth in cork oak productive stands spread on the north (Nebrodi Mountains and south-east (Iblei Mountains of Sicily. Image analysis techniques were used on cork surfaces of transverse sections of planks to measure cork rings. Dendrochronological analysis was applied to study annual fluctuation on rings growth in relation to various climate parameters in a cork cycle production. Results showed that rainfall, summer drought and temperature are determining factors in controlling cork growth. In siliceous areas of Nebrodi Mountains correlation between cork growth index and rainfall indicates that the rain period from May to September strongly influences phellogen activity. Temperature and water stress indices, on the other hand, show a negative correlation with cork growth. In clay and evolved soils of volcanic plateau of Iblei Mountains January precipitation shows a positive correlation with cork growth index. Also absolute minimum temperature in June and absolute maximum temperature in September show a positive correlation when temperature possibly has influence on phellogen activity during growing season.

The coast of Sicily region stretches about 1400 km, bathing three different seas: the North tract, from Messina to Capo San Vito wash to the Tyrrhenian Sea, the oriental side, from Messina to Capo Passero, wash to the Ionian Sea, and finally the southern side wash to the Mediterranean. Of these, 395 km are made up of beaches and 970 km from rocky shores. The coastal morph-type were analyzed in relation to their evolutionary trend (backspace or advancement of the seaside), can be summarized as follows: a low shores of torrent plain (Messina), low shores with salt (Trapani), low shores beaches edged with dunal systems, subject to backspace, where urbanization has reduced or eliminated the internal sand dunes, shores on marine terraces, with beaches at the foot (Agrigento) and high shores non-affected of real phenomena of backspace, but subject to often dangerous events of detachment and collapse of blocks (high rocky shores). The marine and coastal environment is a complex and articulated, in balance with the Earth's environment, in which live together, but through different dynamics strongly interacting, ecosystems and marine ecosystems typically transition. The increasing density of population concentrated along the shores, the gradual expansion of activities related to the use of marine and coastal resources, are some of the issues that threaten the delicate balance of nature and the sea coast. The sicilian coastal areas most subject to erosion are those in Ragusa shores areas in south-eastern of Sicily, where the critical areas interesting low coastline and high shores. Following the coast, between Capo Peloro and Milazzo (Messina),where the erosion affects the coast with a low of about 23 km. In the coastal between Capo St. Marco and Capo Feto (Trapani) the critical areas interesting the low coastline and, in part erodible bluffs. One of this case is localized in the town of Mazara del Vallo. In general, the phenomenon erosive affects almost all the sicilian

The portion of the eastern Sicily coastline (southern Italy), ranging from the southern part of the Catania Gulf (to the north) down to the southern-eastern end of the island, represents a very important geographical domain from the industrial, commercial, military, historical and cultural points of view. Here the two major cities of Augusta and Siracusa are found. In particular, the Augusta bay hosts one of the largest petrochemical poles in the Mediterranean, and Siracusa is listed among the UNESCO World Heritage Sites since 2005. This area was hit by at least seven tsunamis in the approximate time interval from 1600 BC to present, the most famous being the 365, 1169, 1693 and 1908 tsunamis. The choice of this area as one of the sites for the testing of innovative methods for tsunami hazard, vulnerability and risk assessment and reduction is then fully justified. This is being developed in the frame of the EU Project called ASTARTE - Assessment, STrategy And Risk Reduction for Tsunamis in Europe (Grant 603839, 7th FP, ENV.2013.6.4-3). We assess the tsunami hazard for the Augusta-Siracusa area through the worst-case credible scenario technique, which can be schematically divided into the following steps: 1) Selection of five main source areas, both in the near- and in the far-field (Hyblaean-Malta escarpment, Messina Straits, Ionian subduction zone, Calabria offshore, western Hellenic Trench); 2) Choice of potential and credible tsunamigenic faults in each area: 38 faults were selected, with properly assigned magnitude, geometry and focal mechanism; 3) Computation of the maximum tsunami wave elevations along the eastern Sicily coast on a coarse grid (by means of the in-house code UBO-TSUFD) and extraction of the 9 scenarios that produce the largest effects in the target areas of Augusta and Siracusa; 4) For each of the 9 scenarios we run numerical UBO-TSUFD simulations over a set of five nested grids, with grid cells size decreasing from 3 km in the open Ionian

Microbial communities in human-impacted soils of ancient settlements have been proposed to be used as ecofacts (bioindicators) of different ancient anthropogenic activities. In this study, bacterial, archaeal and fungal communities inhabiting soil of three archaic layers, excavated at the archaeological site on Monte Iato (Sicily, Italy) and believed to have been created in a chronological order in archaic times in the context of periodic cultic feasts, were investigated in terms of (i) abundance (phospholipid fatty acid (PLFA) analysis and quantitative PCR)), (ii) carbon(C)-source consumption patterns (Biolog-Ecoplates) and (iii) diversity and community composition (Illumina amplicon sequencing). PLFA analyses demonstrated the existence of living bacteria and fungi in the soil samples of all three layers. The upper layer showed increased levels of organic C, which were not concomitant with an increment in the microbial abundance. In taxonomic terms, the results indicated that bacterial, archaeal and fungal communities were highly diverse, although differences in richness or diversity among the three layers were not detected for any of the communities. However, significantly different microbial C-source utilization patterns and structures of bacterial, archaeal and fungal communities in the three layers confirmed that changing features of soil microbial communities reflect different past human activities.

Knowledge about vegetation and fire history of the mountains of Northern Sicily is scanty. We analysed five sites to fill this gap and used terrestrial plant macrofossils to establish robust radiocarbon chronologies. Palynological records from Gorgo Tondo, Gorgo Lungo, Marcato Cixé, Urgo Pietra Giordano and Gorgo Pollicino show that under natural or near natural conditions, deciduous forests (Quercus pubescens, Q. cerris, Fraxinus ornus, Ulmus), that included a substantial portion of evergreen broadleaved species (Q. suber, Q. ilex, Hedera helix), prevailed in the upper meso-mediterranean belt. Mesophilous deciduous and evergreen broadleaved trees (Fagus sylvatica, Ilex aquifolium) dominated in the natural or quasi-natural forests of the oro-mediterranean belt. Forests were repeatedly opened for agricultural purposes. Fire activity was closely associated with farming, providing evidence that burning was a primary land use tool since Neolithic times. Land use and fire activity intensified during the Early Neolithic at 5000 bc, at the onset of the Bronze Age at 2500 bc and at the onset of the Iron Age at 800 bc. Our data and previous studies suggest that the large majority of open land communities in Sicily, from the coastal lowlands to the mountain areas below the thorny-cushion Astragalus belt (ca. 1,800 m a.s.l.), would rapidly develop into forests if land use ceased. Mesophilous Fagus-Ilex forests developed under warm mid Holocene conditions and were resilient to the combined impacts of humans and climate. The past ecology suggests a resilience of these summer-drought adapted communities to climate warming of about 2 °C. Hence, they may be particularly suited to provide heat and drought-adaptedFagus sylvatica ecotypes for maintaining drought-sensitive Central European beech forests under global warming conditions.

In 1851, the region of Sicily experienced many rainstorm-induced landslides. On 13 March 1851, a rainstorm brought about a severe rockfall disaster near the small town of Sclafani (Madonie Mountains, northern-central Sicily, Italy). Rocks detached from the carbonate crest of Mt Sclafani (813 m above sea level) and fell downslope, causing the collapse of the ancient hydrothermal spa (about 430 m above sea level) and burying it. Fortunately, there were no injuries or victims. Given its geological, geomorphological and tectonic features, the calcareous-dolomitic and carbonate-siliciclastic relief of Mt Sclafani is extremely prone to landsliding. This study combines the findings of detailed geological and geomorphological field surveys and of a critical review of documentary data. A thorough analysis of documentary sources and historical maps made it possible to identify the location (previously unknown) of the ancient spa. The rockfall dynamics was reconstructed by comparing field reconnaissance data and documentary sources. The 1851 event reconstruction is an example of the application of an integrated methodological approach, which can yield a propaedeutic, yet meaningful picture of a natural disaster, paving the way for further research (e.g. slope failure susceptibility, future land-use planning, protection of thermal springs and mitigation of the impact of similar disasters in this area). Indeed, the intensification of extreme weather events, caused by global warming induced by climate change, has increased the risk of recurrence of a catastrophic event, like that of the ancient Sclafani spa, which is always a potential threat.

Eastern Sicily is affected by earthquakes and tsunamis of local and remote origin, which is known through numerous historical chronicles. Recent studies have put emphasis on the role of submarine landslides as the direct cause of the main local tsunamis, envisaging that earthquakes (in 1693 and 1908) did produce a tsunami, but also that they triggered mass failures that were able to generate an even larger tsunami. The debate is still open, and though no general consensus has been found among scientists so far, this research had the merit to attract attention on possible generation of tsunamis by landslides off Sicily. In this paper we investigate the tsunami potential of mass failures along one sector of the Hyblean-Malta Escarpment (HME). facing Augusta. The HME is the main offshore geological structure of the region running almost parallel to the coast, off eastern Sicily. Here, bottom morphology and slope steepness favour soil failures. In our work we study slope stability under seismic load along a number of HME transects by using the Minimun Lithostatic Deviation (MLD) method, which is based on the limit-equilibrium theory. The main goal is to identify sectors of the HME that could be unstable under the effect of realistic earthquakes. We estimate the possible landslide volume and use it as input for numerical codes to simulate the landslide motion and the consequent tsunami. This is an important step for the assessment of the tsunami hazard in eastern Sicily and for local tsunami mitigation policies. It is also important in view of tsunami warning system since it can help to identify the minimum earthquake magnitude capable of triggering destructive tsunamis induced by landslides, and therefore to set up appropriate knowledge-based criteria to launch alert to the population.

Dianthus rupicola Biv. (cliffs carnation) is a camephytic, suffruticous, perennial plant growing up to 40 cm high. The plant is widespread in Sicily and neighbouring islands (Egadi, Lampedusa, Lipari) and in some areas of southern Italy. GC and GC-MS analyses of the essential oil distilled from the flowers showed the presence of 66 components. Its composition is characterised by the high content of thymol and carvacrol derivatives. A good antibacterial activity against Bacillus cereus and Bacillussubtilis, both infesting cellulosic historical material, was shown, whereas the antioxidant capacity was determined to be quite poor.

The seismic events caused by human engineering activities are commonly termed as "triggered" and "induced". This class of earthquakes, though characterized by low-to-moderate magnitude, have significant social and economical implications since they occur close to the engineering activity responsible for triggering/inducing them and can be felt by the inhabitants living nearby, and may even produce damage. One of the first well-documented examples of induced seismicity was observed in 1932 in Algeria, when a shallow magnitude 3.0 earthquake occurred close to the Oued Fodda Dam. By the continuous global improvement of seismic monitoring networks, numerous other examples of human-induced earthquakes have been identified. Induced earthquakes occur at shallow depths and are related to a number of human activities, such as fluid injection under high pressure (e.g. waste-water disposal in deep wells, hydrofracturing activities in enhanced geothermal systems and oil recovery, shale-gas fracking, natural and CO2 gas storage), hydrocarbon exploitation, groundwater extraction, deep underground mining, large water impoundments and underground nuclear tests. In Italy, induced/triggered seismicity is suspected to have contributed to the disaster of the Vajont dam in 1963. Despite this suspected case and the presence in the Italian territory of a large amount of engineering activities "capable" of inducing seismicity, no extensive researches on this topic have been conducted to date. Hence, in order to improve knowledge and correctly assess the potential hazard at a specific location in the future, here we started a preliminary study on the entire range of engineering activities currently located in Sicily (Southern Italy) which may "potentially" induce seismicity. To this end, we performed: • a preliminary census of all engineering activities located in the study area by collecting all the useful information coming from available on-line catalogues; • a detailed compilation

In order to determine the prevalence of human papillomavirus (HPV) infection in sexually active female population in Messina, we tested cervical scrapes of women referred to university clinics for routine gynaecologic care. Between March and December 2008, a total of 680 cervical samples of 598 patients (573 Italian from province of Messina and 25 resident aliens) were examined consecutively from laboratory of molecular biology at the Department of Human Pathology. For each sample, cervical cells were collected by centrifugation and DNA was extracted (QIAamp DNA mini kit, Qiagen), followed by a PCR-based HPV DNA assay and reverse dot blot genotyping (HPV-HS Bio plus HPV-strip, AB Analytica or HPV-type, AB Analytica). The overall rate of HPV DNA detection in Italian patients (mean age 34 years; range 15-69) was 70.5% (404/573), with 163 cases of multiple infections (40.3%). In 335 patients (82.9%) a high-risk HPV infection was detected. In this group the coexistence of a low-risk HPV infection was documented in 97 cases while 65 patients exhibited only a low-risk HPV infection. HPV-16 was the most prevalent (33.4%), followed by HPV-6 (28.0%), HPV-31 (24.3%), HPV-58 (11.4%), HPV-66 (11.1%), HPV-53 (6.4%), HPV-18 (6.2%), HPV-56 (5.4%), HPV-33 (5.2%) while the other genotypes identified (HPV-11, -40, -42, -43, -44, -54, -61, -70, -81, -26, -35, -39, -45, -51, -52, -59, -68, -73, -82) were below 5%. HPV prevalence (any type) was 78.7% at age or =45 years. A significant association (chi2=12.718; P=0.006) between HPV DNA detection and the younger age was encountered. Since available data on the prevalence and distribution of HPV infection in Italy are somewhat discordant, this study represents a helpful contribution to the knowledge on the circulation of precise genotypes in east Sicily in order to improve new HPV vaccines.

We processed crustal seismic profile SIRIPRO, acquired across Central Sicily. To improve the seismic image we utilized the wave equation datuming technique, a process of upward or downward continuation of the wave-field between two arbitrarily shaped surfaces. Wave equation datuming was applied to move shots and receivers to a given datum plane, removing time shifts related to topography and to near-surface velocity variations. The datuming procedure largely contributed to attenuate ground roll, enhance higher frequencies, increase resolution and improve the signal/noise ratio. Processed data allow recognizing geometries of crust structures differentiating seismic facies and offering a direct image of ongoing tectonic setting within variable lithologies characterizing the crust of Central Sicily. Migrated sections underline distinctive features of Hyblean Plateau foreland and above all a crustal thinning towards the Caltanissetta trough, to the contact with a likely deep Permo-Triassic rifted basin or rather a zone of a continent to oceanic transition. Inhomogeneity and fragmentation of Sicily crust, with a distinct separation of Central Sicily basin from western and eastern blocks, appear to have guided the tectonic transport inside the Caltanissetta crustal scale syncline and the accumulation of allochthonous terrains with south and north-verging thrusts. Major tectonic stack operated on the construction of a wide anticline of the Maghrebian chain in northern Sicily. Sequential south-verging imbrications of deep elements forming the anticline core denote a crust wedge indenting foreland structures. Deformation processes involved multiple detachment planes down to decoupling levels located near crust/mantle transition, supporting a presence of high-density lenses beneath the chain, interrelated to a southwards push of Tyrrhenian mantle and asthenosphere.

This study aims at comparing the performances of Binary Logistic Regression (BLR) and Boosted Regression Trees (BRT) methods in assessing landslide susceptibility for multiple-occurrence regional landslide events within the Mediterranean region. A test area was selected in the north-eastern sector of Sicily (southern Italy), corresponding to the catchments of the Briga and the Giampilieri streams both stretching for few kilometres from the Peloritan ridge (eastern Sicily, Italy) to the Ionian sea. This area was struck on the 1st October 2009 by an extreme climatic event resulting in thousands of rapid shallow landslides, mainly of debris flows and debris avalanches types involving the weathered layer of a low to high grade metamorphic bedrock. Exploiting the same set of predictors and the 2009 landslide archive, BLR- and BRT-based susceptibility models were obtained for the two catchments separately, adopting a random partition (RP) technique for validation; besides, the models trained in one of the two catchments (Briga) were tested in predicting the landslide distribution in the other (Giampilieri), adopting a spatial partition (SP) based validation procedure. All the validation procedures were based on multi-folds tests so to evaluate and compare the reliability of the fitting, the prediction skill, the coherence in the predictor selection and the precision of the susceptibility estimates. All the obtained models for the two methods produced very high predictive performances, with a general congruence between BLR and BRT in the predictor importance. In particular, the research highlighted that BRT-models reached a higher prediction performance with respect to BLR-models, for RP based modelling, whilst for the SP-based models the difference in predictive skills between the two methods dropped drastically, converging to an analogous excellent performance. However, when looking at the precision of the probability estimates, BLR demonstrated to produce more robust

Marked uncertainties persist regarding the climatic evolution of the Mediterranean region during the Holocene. For instance, whether moisture availability gradually decreased, remained relatively constant, or increased during the last 7000 years remains a matter of debate. To assess Holocene limnology, hydrology and moisture dynamics, the coastal lakes Lago Preola and Gorgo Basso, located in southwestern Sicily, were investigated through several stratigraphic analyses of ostracodes, including multivariate analyses of assemblages, transfer functions of salinity, and biochemical analyses of valves (Sr/Ca, δ18O and δ13C). During the early Holocene, the Gorgo Basso and Lago Preola ostracode records are similar. After an initial period of moderate salinity (1690–6100 mg/l from ca. 10,000–8190 cal yr BP), syndepositional or diagenetic dissolution of ostracode valves suggests that salinity declined to Greek civilization took root in Sicily (2600 cal yr BP), and it completely dominates the record during Roman occupation (roughly 2100 to 1700 cal yr BP). These freshwater conditions at Gorgo Basso suggest high effective moisture when evergreen olive-oak forests collapsed in response to increased Greco-Roman land use and fire. Ostracode valve geochemistry (Sr/Ca, δ18O) suggests significant changes in early vs. late Holocene hydrochemistry, either as changes in salinity or in the seasonality of precipitation. Harmonizing the autecological and geochemical data from Gorgo Basso suggests the latter was more likely, with relatively more late Holocene precipitation falling during the spring, summer, and fall, than winter compared to the early Holocene. Our ostracode-inferred paleosalinity data indicate that moisture availability did not decline during the late Holocene in the central Mediterranean region. Instead, moisture availability was lowest during the early Holocene, and most abundant during the late Holocene.

Full Text Available In order to obtain a reliable map of the present-day stress field in Italy, needed to better understand the active tectonic processes and to contribute to the assessment of seismic hazard, in 1992 we started to collect and analyze new data from borehole breakouts in deep oil and geothermal wells and focal mechanisms of earthquakes (2.5 < M <5 occurred in Italy between 1988 and 1995. From about 200 deep wells and 300 focal mechanisms analyzed to date, we infer that: the internal (SW sector of the Northern Apenninic arc is extending with minimum compressional stress (Shmin oriented ? ENE, while the external front is thrusting over the Adriatic foreland (Shmin ? NW-SE. The entire Southern Apennine is extending in NE direction (from the Tyrrhenian margin to the Apulian foreland and compression (in the foredeep is no longer active at the outer (NE thrust front. Between these two arcs, an abrupt change in the tectonic regime is detected with directions of horizontal stress changing by as much as 90º in the external front, around latitude 430N. Along the Ionian side of the Calabrian arc the stress directions inferred from breakouts and focal mechanisms are scattered with a hint of rotation from N-S Shmin close to the Southern Apennines, to ~ E-W directions in the Messina Strait. In Sicily, a NW-SE direction of SHmax is evident in the Hyblean foreland, parallel to the direction of plate motion between Africa and Europe. A more complex pattern of stress directions is observed in the thrust belt zone, with rotations from the regional trend (NW í directed SHmax to NE oriented SHmax. A predominant NW direction of SHmax is also detected in mainland Sicily from earthquake focal mechanisms, but no well data are available in this region. In the northern part of Sicily (Aeolian Islands a ~N-S direction of SHmax is observed.

The study was aimed at investigating perception of, attitudes toward, and knowledge of epilepsy among college students of the University of Messina in Sicily (Italy), high school students, and teachers from Sicily in order to structure health educational programs to remediate inadequate knowledge and stigma about epilepsy. Participants in this study consisted of 932 subjects (571 males, 361 females) aged between 13 and 63 years old (M 21.75 ± 8.7): 571 college students aged between 18 and 35 years old (M 21.54 ± 2.59), 62 teachers aged between 38 and 63 years old (M 51.18 ± 6.27), and 299 high school students aged between 13 and 19 years old (M 16.05 ± 1.67). Measures were two anonymous questionnaires to collect sociodemographic information and to assess knowledge of, attitudes toward, and perception of epilepsy. Analyses were performed with descriptive statistical analysis (mean, standard deviation, frequency counts, and percentages) and Mann-Whitney U-test nonparametric for two independent samples. This study provides general information about psychosocial aspects of epilepsy in Sicily which provides the basis for further studies and the development of interventions to eliminate prejudices against persons with epilepsy and related myths.

2011-01-01

Full Text Available Flow duration curves are simple and powerful tools to deal with many hydrological and environmental problems related to water quality assessment, water-use assessment and water allocation. Unfortunately the scarcity of streamflow data enables the use of these instruments only for gauged basins. A regional model is developed here for estimating flow duration curves at ungauged basins in Sicily, Italy. Due to the complex ephemeral behavior of the examined region, this study distinguishes dry periods, when flows are zero, from wet periods using a three parameters power law to describe the frequency distribution of flows. A large dataset of streamflows has been analyzed and the parameters of flow duration curves have been derived for about fifty basins. Regional regression equations have been developed to derive flow duration curves starting from morphological basin characteristics.

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

A PEDOTRANSFER FUNCTION FOR ESTIMATING THE SOIL ERODIBILITY FACTOR IN SICILY

Directory of Open Access Journals (Sweden)

Vincenzo Bagarello

2009-09-01

Full Text Available The soil erodibility factor, K, of the Universal Soil Loss Equation (USLE is a simple descriptor of the soil susceptibility to rill and interrill erosion. The original procedure for determining K needs a knowledge of soil particle size distribution (PSD, soil organic matter, OM, content, and soil structure and permeability characteristics. However, OM data are often missing and soil structure and permeability are not easily evaluated in regional analyses. The objective of this investigation was to develop a pedotransfer function (PTF for estimating the K factor of the USLE in Sicily (south Italy using only soil textural data. The nomograph soil erodibility factor and its associated first approximation, K’, were determined at 471 sampling points distributed throughout the island of Sicily. Two existing relationships for estimating K on the basis of the measured geometric mean particle diameter were initially tested. Then, two alternative PTFs for estimating K’ and K, respectively, on the basis of the measured PSD were derived. Testing analysis showed that the K estimate by the proposed PTF (eq.11, which was characterized by a Nash-Suttcliffe efficiency index, NSEI, varying between 0.68 and 0.76, depending on the considered data set, was appreciably more accurate than the one obtained by other existing equations, yielding NSEI values varying between 0.21 and 0.32.

The plants, rituals and spells that 'cured' helminthiasis in Sicily

Napoli, Mariangela

2008-01-01

Background The author reports on the plants, rituals and spells used against worms and the so-called scantu (fright) in some areas of Sicily. The work is based on ethnobotanical research carried out, prevalently, between 2002-2006, in some areas of Eastern, South-Eastern, North-Central and South-Central Sicily. Methods This research is based on dialogue. Senior 'healers' were contacted; furthermore, doctors, teachers, farmers and in general 'experts' with herbs and 'magic' rituals. Information was collected about the way the plants of folk medicine are prepared. The interviewees were also invited to recite prayers and spells against helminthiasis. Results The author has highlighted the importance of how, in some parts of Sicily, some ailments like helminthiasis and other correlated pathologies like scantu are 'treated' and, especially within the rural social classes, by folk medicine remedies, herbal practises, particular prayers, rituals and spells. Conclusion As regards health/illness, it should be noted that in the last ten years conventional medicine has provided very satisfactory results even resolving potentially mortal pathologies. However, in certain social classes, there is no real collaboration between conventional and folk medicine; so for some senior citizens, the 'healer' with his rituals and empirical and magical herbs is still the person to turn to for the 'cure' of particular ailments. Interest in these practises from ancestral heritage in an advanced country like Italy, is only relevant if the aim is to recoup a cultural identity which is already in decline. It is significant to report a piece: on 14 October 2007 the news on a well-known national Italian TV channel reported an interview with a 94 year-old man from Arbatax (Sardinia) referred to as a 'healer' because both his townspeople and others from all over the world go to him for his cures. He is not paid except in kind and has been known to cure St. Anthony's fire, burns, scalding and marine

2010-04-01

Full Text Available Basing on literature data and unpublished relevés from Sicily, a survey of the syntaxa belonging to the class Lygeo-Stipetea Rivas-Martínez 1978 is presented. This perennial vegetation is characterized by the dominance of big caespitose hemicryptophytes, and it is widely distributed in Sicily from the sea level up to 1500 m a.s.l. The class is represented in Sicily by two orders, floristically and ecologically well differentiated: Lygeo-Stipetalia, including the sole alliance Moricandio-Lygeion exclusively of clayey substrates, and Hyparrhenietalia hirtae, including five alliances (Hyparrhenion hirtae, Avenulo cincinnatae-Ampelodesmion mauritanici, Thero-Brachypodion ramosi, Bromo-Oryzopsion miliaceae, and Arundion collinae occurring on various substrates. Within the class, 50 associations have been recognized. To support the syntaxonomic proposal, a multivariate numerical analysis, considering literature and personal data, has been performed. Nomenclature, floristic settlement, ecology, syndynamism and chorology are examined for each syntaxon.

2006-07-01

Full Text Available This paper describes two casts of a suid from the Late Miocene of Gravitelli (Messina, Sicily, originally described by Seguenza in 1902. The entire Gravitelli faunal collection was lost in the early 1900¡¦s. The recent rediscovery of two casts in the collections of the Museo di Storia Naturale of the University of Florence represent the only available material from this locality (in addition to the original description and illustration by Seguenza. The study of these casts allow a revision of the Gravitelli suid and its attribution to the genus Propotamochoerus. Although a specific determination is not possible, we suggest probable affinities with the species P. hysudricus or P. provincialis.

Comparative Analysis of Spatial Interpolation Methods in the Mediterranean Area: Application to Temperature in Sicily

Directory of Open Access Journals (Sweden)

Annalisa Di Piazza

2015-04-01

Full Text Available An exhaustive comparison among different spatial interpolation algorithms was carried out in order to derive annual and monthly air temperature maps for Sicily (Italy. Deterministic, data-driven and geostatistics algorithms were used, in some cases adding the elevation information and other physiographic variables to improve the performance of interpolation techniques and the reconstruction of the air temperature field. The dataset is given by air temperature data coming from 84 stations spread around the island of Sicily. The interpolation algorithms were optimized by using a subset of the available dataset, while the remaining subset was used to validate the results in terms of the accuracy and bias of the estimates. Validation results indicate that univariate methods, which neglect the information from physiographic variables, significantly entail the largest errors, while performances improve when such parameters are taken into account. The best results at the annual scale have been obtained using the the ordinary kriging of residuals from linear regression and from the artificial neural network algorithm, while, at the monthly scale, a Fourier-series algorithm has been used to downscale mean annual temperature to reproduce monthly values in the annual cycle.

Cardiac filariosis in migratory Mute swans (Cygnus olor in Sicily

2016-09-01

Full Text Available Sarconema eurycerca is a common parasitic disease of North America swans and geese. The infection has been correlated with severe heart lesions, often resulting in cardiac failure and death of the animals. Heartworms infections have been previously reported in European swans, and specifically in the United Kingdom and Nederland. Both the countries are characterized by a cold temperate weather, similar to the one that can be found in swan wintering areas of U.S.A. and Canada. The first record of cardiac filariasis associated with Sarconema eurycerca infection in four swans in Italy. Twelve mute swans were examined during avian influenza surveillance activities on migratory birds. Birds were collected in the year 2006, in wintering areas of Eastern Sicily (Italy. Four of the twelve swans showed necrotic-haemorrhagic myocarditis with intra-lesional nematodes. Morphological characteristics identified the parasite as a filarial nematode. Birds lungs samples were used for parasites DNA extraction. The latter was used as template for polymerase chain reaction (PCR amplification and sequencing of part of the 12S rDNA gene. Comparison of genomic DNA extracted from a reference S. eurycerca isolate confirmed parasite identity and provided the first sequence resources for this species of value to future diagnostic and epidemiological studies.

Full Text Available BackgroundAnaplastic thyroid cancer (ATC is a rare but extremely aggressive cancer of the thyroid, contributing up to 30–40% of thyroid cancer-specific mortality. We analyzed ATC characteristics and survival rates in Sicily to evaluate the possible influence of environmental factors. With this aim, data regarding ATC incidences in urban/rural and industrial, iodine-deficient, and volcanic vs control areas were compared in Sicily as well as ATC data from Sicily and USA.MethodsUsing the Sicilian Register of Thyroid Cancer (SRTC database incidence, age, gender, tumor size and histotype, extrathyroidal extension, stage, and coexistence with pre-existing differentiated thyroid cancer (DTC were evaluated in different areas of Sicily and also compared with Surveillance Epidemiology and End Results data in USA.ResultsForty-three ATCs were identified in Sicily in the period 2002–2009. In our series only age <70 years at diagnosis (p = 0.01, coexistence with DTC (p = 0.027 and tumor size ≤6 cm (p = 0.012 were significant factors for increased survival at univariate analysis (only age at multivariate analysis. No difference in ATC incidence was found in urban vs rural areas and in iodine-deficient and industrial vs control areas. By contrast, in the volcanic area of Sicily, where DTC incidence is doubled relative to the rest of the island, also ATC incidence was increased. ATC data in Sicily were similar to those reported in the same period in the USA where overall survival rate at 6 and 12 months, however, was smaller.ConclusionThe similar ATC data observed in Sicily and USA (having different genetic background and lifestyle and the increased ATC incidence in the volcanic area of Sicily paralleling the increased incidence of papillary thyroid cancer are compatible with the possibility that casual additional mutations, more frequent in a background of increased cell replication like DCT, are the major causes of ATC rather than

Archaeometric investigation of red-figured pottery fragments from Gioiosa Guardia (Messina, Sicily) by INAA, FT-IR and TOF-ND techniques

Barilaro, D.; Crupi, V.; Interdonato, S.

2008-01-01

The present work is addressed to the study of some precious ancient pottery fragments, coming from the archaeological site of Gioiosa Guardia, in the Tirrenean Coast of Sicily. On the basis of historical and aesthetic considerations, the findings are dated back to 6.-5. Century b.C. and show a surface entirely decorated by red-figured technique, typical of Attic production. Many doubts arise about the real provenance of the artefacts. On one side, they could come directly from Greece, as attested by trading patterns between Greece and Southern Italy, on the other side, they could be produced in Sicily under the Greek artistic influence. In order to obtain a detailed characterization of the samples, a microdistruttive investigation was performed by Instrumental Neutron Activation Analysis (INAA), Fourier transform infrared absorption (FT-IR) and a non-invasive analysis by time-of-flight neutron diffraction (TOF-ND). Starting from the identification of the mineralogical and geochemical composition, a correct classification of the shards can be achieved.

Tectonic forcing causes the relief-building of mountain chains and enforces the surficial processes in a persistent dismantling of rock volumes, continuously modelling Earth's surface. Actually, we observe transient landscapes that have temporarily recorded tectonic forcing as a codified signal. The Late Quaternary tectonic evolution of northeastern Sicily, located along the Nubia-Eurasia plate boundary at the southern termination of the Calabrian arc, has been dominated by intense Plio-Pleistocene dynamics that severely modified the Late Miocene landscape. The present work aims to investigate geomorphically northeastern Sicily, essentially focusing on the hypsometric and relief analyses of the region in order to define how the topography responds to the post-Pliocene tectonic deformation. We apply different relief morphometric indices (Hypsometric Integral, Topographic Relief and Topographic Dissection) measured for each differently sized moving window, and we use different swath topographic profiles as well. Our analysis evidences differential morphological responses between distinct morphotectonic domains of the studied area, led by the combination of earlier morphological background and Late Quaternary tectonic deformation stages of the region. In addition, in the context of a constant and uniform tectonic uplift, the results define the general space- and time-relating pathways of the landscape geomorphic metrics. This enables us to bring out the controls of the vertical scale of landscape on hypsometry, exploring their mutual relationships. Finally, we reconstruct the Late Quaternary morphotectonic evolution of the region, defining the role played by the main tectonic alignments on the present geomorphic setting.

New High Voltage Interconnections with Islands in the Mediterranean Sea: Malta and Sicily. Analysis of the Effects on Renewable Energy Sources Integration and Benefits for the Electricity Market

2018-04-01

Full Text Available The present paper shows the benefits coming from the operation of the recent electrical high voltage (HV interconnections between Sicily, Malta and mainland Italy. These new interconnections allow zonal prices of electricity considerably lower than in the past, ensuring greater flexibility to the system and a better integration of Renewable Energy Sources (RES. After briefly illustrating the two high-voltage electrical systems (Sicily and Malta, and having provided a description of the interconnection cable with Malta and its protection devices, the authors hypothesized two modes of operation (Sicily-Malta system islanded or interconnected to the rest of Europe. For the first case (islanded some simulations are performed through the use of an electric network model realized in the Neplan® environment, and for the second case an analysis of one year real data was made. The results of the simulation, thanks to the use of a power flow tracing method, show that this new interconnection between the two islands (Sicily and Malta allows an important improvement in the integration and dispatching of the power generated by RES of the Sicilian territory, better operation of traditional Sicilian generation units, lower electricity zonal prices and a significant reduction in emissions from obsolete fuel oil thermal units located in Malta.

The crustal velocity field mosaic of the Alpine Mediterranean area (Italy): Insights from new geodetic data

Farolfi, Gregorio; Del Ventisette, Chiara

2016-04-01

A new horizontal crustal velocity field of Alpine Mediterranean area was determined by continuous long time series (6.5 years) of 113 Global Navigation Satellite System (GNSS) permanent stations. The processing was performed using state-of-the-art absolute antenna phase center correction model and recomputed precise IGS orbits available since April 2014. Moreover, a new more accurate tropospheric mapping function for geodetic applications was adopted. Results provide a new detailed map of the kinematics throughout the entire study area. This area is characterized by a complex tectonic setting driven by the interaction of Eurasian and African plates. The eastern Alps, Corsica, Sardinia and the Tyrrhenian Sea (which is covered only by interpolation data) show small velocity residuals with respect to the Eurasian plate. The whole Apennines axis discriminates two different velocity patterns, the Adriatic and the Tyrrhenian area. The area around Messina Strait, which separates peninsular Italy and Sicily, represents a poorly understood region. Results identify an important boundary zone between two different domains, Calabria and Sicily, which are characterized by different crustal motions. The northeastern part of Sicily and Calabria move like Adriatic area, whilst the rest of Sicily, Malta and Lampedusa are dominated by African motion.

Therefore, the Byzantine chant heritage in Sicily is not an inflexible and static musical tradition, but it envisages a dynamic mode of existence, susceptible to changes, and maintained by interior principles...... of organisation. After five centuries of oral transmission, it still lives, despite, or maybe thanks to the lack of ‘original’ written sources, and it might thus be seen as a multi-layered musical tradition, featuring multiple versions and encompassing a certain degree of melodic heterogeneity....

Presence-only approach to assess landslide triggering-thickness susceptibility: a test for the Mili catchment (north-eastern Sicily, Italy)

KAUST Repository

Lombardo, Luigi

2016-06-29

This study evaluates the performances of the presence-only approach, Maximum Entropy, in assessing landslide triggering-thickness susceptibility within the Mili catchment (Sicily, Italy). This catchment underwent several meteorological stresses, resulting in hundreds of shallow rapid mass movements between 2007 and 2011. In particular, the area has become known for two disasters, which occurred in 2009 and 2010; the first weather system did not pass directly over the catchment; however, peak rainfall was registered over the basin during the second meteorological event. Field data were collected to associate the depth from the slope surface that material was mobilised at the triggering zone to each mass movement within the catchment. This information has been used to model the landslide susceptibility for two classes of processes, divided into shallow failures for maximum depths of 1 m and deep ones in case of values equal or greater than 1 m. Topographic attributes from a 2-m DEM were used as predictors, together with medium resolution vegetation indexes derived from ASTER scenes and geological, land use and tectonic maps. The presence-only approach discriminated between the two depth classes at the landslide trigger zone, producing excellent prediction skills associated with relatively low variances across a set of 50 randomly generated replicates. The role of each predictor was assessed to ascertain the significance to the final model output. This work uses simple field measurements to produce triggering-thickness susceptibility, which is a novel approach and may perform better as a proxy for landslide hazard assessments with respect to more common susceptibility practises. © 2016, Springer Science+Business Media Dordrecht.

Soil erosion by water constitutes a serious problem affecting various countries. In the last few years, a number of studies have adopted statistical approaches for erosion susceptibility zonation. In this study, the Stochastic Gradient Treeboost (SGT) was tested as a multivariate statistical tool for exploring, analyzing and predicting the spatial occurrence of rill-interrill erosion and gully erosion. This technique implements the stochastic gradient boosting algorithm with a tree-based method. The study area is a 9.5 km2 river catchment located in central-northern Sicily (Italy), where water erosion processes are prevalent, and affect the agricultural productivity of local communities. In order to model soil erosion by water, the spatial distribution of landforms due to rill-interrill and gully erosion was mapped and 12 environmental variables were selected as predictors. Four calibration and four validation subsets were obtained by randomly extracting sets of negative cases, both for rill-interrill erosion and gully erosion models. The results of validation, based on receiving operating characteristic (ROC) curves, showed excellent to outstanding accuracies of the models, and thus a high prediction skill. Moreover, SGT allowed us to explore the relationships between erosion landforms and predictors. A different suite of predictor variables was found to be important for the two models. Elevation, aspect, landform classification and land-use are the main controlling factors for rill-interrill erosion, whilst the stream power index, plan curvature and the topographic wetness index were the most important independent variables for gullies. Finally, an ROC plot analysis made it possible to define a threshold value to classify cells according to the presence/absence of the two erosion processes. Hence, by heuristically combining the resulting rill-interrill erosion and gully erosion susceptibility maps, an integrated water erosion susceptibility map was created. The

There is evidence that many geophysical processesexhibit long-term persistence(LTP, also calledlong-range dependence). Overlooking this type of behaviorcan lead to wrong inferences and false claims about the properties of processes studied in the fields of hydrology, hydraulics, meteorology, and engineering. In this light, the present study investigates the statistical properties of precipitation and temperature datasets from Sicily (Italy),in order to analyzethe presence of LTP. The case study region(i.e., the largest island in the Mediterranean)is characterized by typical Mediterranean climate with mild winter and severe drought conditions in summer time. The latter have become one of the most challenging issuesall over the Mediterranean region due to the growth of population, contamination of water supplies, and expansion of agricultural, energy and industrial sectors. The severity and duration of the drought eventsare clearly influenced by the presence of LTP in precipitation and temperature processes. Improving understanding ofsuch phenomenonis therefore central to new research challenges related to the estimation and management of water resources.

A molecular survey of Rickettsia felis in fleas from cats and dogs in Sicily (Southern Italy.

Directory of Open Access Journals (Sweden)

Elisabetta Giudice

Full Text Available Rickettsia felis, the agent of flea-borne spotted fever, has a cosmopolitan distribution. Its pathogenic role in humans has been demonstrated through molecular and serologic tests in several cases. The cat flea (Ctenocephalides felis is considered the main reservoir and the biological vector. The aim of this study was to assess the presence and occurrence of R. felis in fleas collected from dogs and cats in various sites of Palermo (Sicily. Between August and October 2012, 134 fleas were collected from 42 animals: 37 fleas from 13 dogs and 97 fleas from 29 cats. Two species of fleas were identified: 132 Ctenocephalides felis (98.51% collected on all animals and only two C. canis (1.49% on one dog. Out of 132 C. felis, 34 (25.76%, 12 from dogs (32.43% and 22 (22.68% from cats, were positive for R. felis DNA by a polymerase chain reaction (PCR, confirmed by sequencing. The only two C. canis fleas were negative. About half of examined animals (47.62%, 20/42 were infested with at least one infected flea; in particular 46.15% of dogs (6/13 and 48.28% of cats (14/29. It seems that in the Palermo district there is a peri-domestic cycle, with a relatively high prevalence of R. felis infection in the cat flea, an insect widely diffused in home environments and which can frequently bite humans. The results also suggest that R. felis should be considered in the human differential diagnosis of any spotted-like fever or febrile illness without a clear source of infection in Sicily, especially if the patient is known to have been exposed to flea bites.

Spatial data fusion and analysis for soil characterization: a case study in a coastal basin of south-western Sicily (southern Italy

Full Text Available Salinization is one of the most serious problems confronting sustainable agriculture in semi-arid and arid regions. Accurate mapping of soil salinization and the associated risk represent a fundamental step in planning agricultural and remediation activities. Geostatistical analysis is very useful for soil quality assessment because it makes it possible to determine the spatial relationships between selected variables and to produce synthetic maps of spatial variation. The main objective of this paper was to map the soil salinization risk in the Delia-Nivolelli alluvial basin (south-western Sicily, southern Italy, using multivariate geostatistical techniques and a set of topographical, physical and soil hydraulic properties. Elevation data were collected from existing topographic maps and analysed preliminarily to improve the estimate precision of sparsely sampled primary variables. For interpolation multi-collocated cokriging was applied to the dataset, including textural and hydraulic properties and electrical conductivity measurements carried out on 128 collected soil samples, using elevation data as auxiliary variable. Spatial dependence among elevation and physical soil properties was explored with factorial kriging analysis (FKA that could isolate and display the sources of variation acting at different spatial scales. FKA isolated significant regionalised factors which give a concise description of the complex soil physical variability at the different selected spatial scales. These factors mapped, allowed the delineation of zones at different salinisation risk to be managed separately to control and prevent salinization risk. The proposed methodology could be a valid support for land use and soil remediation planning at regional scale.

Full Text Available Human papillomaviruses (HPVs are etiological agents of cervical cancer. In the absence of Pap smear alterations, high-risk HPV DNA can be detected in cervical samples. The prevalence of papillomavirus infection and their genotype distribution varies greatly across populations. The aims of this study were: i to assess the prevalences of HPV genotypes in people living in Eastern Sicily (Italy and the frequency of HPV multiple infections; ii to evaluate the association between HPV genotypes and cervical lesions in order to improve the epidemiological knowledge useful for monitoring or treating infected women. Nested PCR and reverse dot/blot hybridization were used for the detection and typing of HPV DNA in 315 women who had had an abnormal PAP-smear. HPV DNA test was positive in 70.5% cases; the prevalence was 50% in atypical squamous cells of undetermined significance (ASCUS, 80.8% in low grade-, and 76.2% in high grade-squamous intraepithelial lesion (H-SIL. The genotype distribution showed a predominance of HPV-16 (56.7% followed by HPV-18 (12.2%, HPV-31 (9.5% and HPV-6 (9.5%. Multiple infections were detected in 35.1% of the infected patients. High frequency of positive results for HPV was confirmed and, even in case of ASCUS, patients should be taken into account for genotyping. Our data indicate that multiple infections are consistent in women with low-grade lesions while they are less frequent in women with H-SIL. This could reinforce the theory of the multi-stage cancer model, by which one HPV type becomes predominant along with the progression of cervical lesion severity.

The genus Pestivirus, which belongs to the Flaviviridae family, includes ssRNA+ viruses responsible for infectious diseases in pigs, cattle, sheep, goats and other domestic and wild ruminants. Like most of the RNA viruses, pestivirus has high genome variability with practical consequences on disease epidemiology, diagnosis and control. In addition to the officially recognized species in the genus Pestivirus, such as BVDV-1, BVDV-2, BDV and CSFV, other pestiviruses have been detected. Furthermore, most of the ruminant pestiviruses show low or absent species specificity observed in serological tests and are able to infect multiple species. Particularly, small ruminants are receptive hosts of the most heterogeneous group of pestiviruses. The aim of this study was to carry out the molecular characterization of pestiviruses isolated from sheep and goats in Sicily, Italy. Phylogenetic analysis of two viral genomic regions (a fragment of 5'-UTR and the whole N pro regions) revealed the presence of different pestivirus genotypes in the analysed goat and sheep herds. Two of five viral isolates were clustered with BVDV-1d viruses, a strain widespread in Italy, but never reported in Sicily. The other three isolates formed a distinct cluster with high similarity to Tunisian isolates, recently proposed as a new pestivirus species. This represents the first evidence for Tunisian-like pestivirus presence in small ruminants in Italy. Furthermore, one of the isolates was collected from a goat, representing the first isolation of Tunisian-like pestivirus from this species. © 2016 Blackwell Verlag GmbH.

Understanding the processes involved in weathering and experimental alteration of glassy materials. The case of some volcanic glasses from eastern Sicily (Italy)

International Nuclear Information System (INIS)

Liotta, Angelo

2014-01-01

The objective of this thesis is to study the effects of weathering and experimental alteration in order to understand the geochemical processes involved and the variation of mineral phases in altered natural glasses. For the first time, five samples of natural volcanic glasses having different composition were collected in eastern Sicily (Italy) in order to be artificially altered and analyzed. The study of naturally altered samples has allowed to observe the effects of weathering after a period of time corresponding to the age of the sample. Moreover, the use of samples of natural glass of volcanic origin has allowed to obtain some powder or thin plates of fresh silicate glass that have been subjected to artificial alteration in the laboratory, in order to model the geochemical processes that have occurred. Alteration experiments were conducted in pure water at 90 C; samples have been altered from 1 to 1000 days of experiment. The characterization of the samples was obtained by Raman spectroscopy, which showed the effects of the devitrification and the presence of some secondary minerals such as carbonates and anatase on the obsidian thin plates, but also phillipsite and chabazite, two varieties of zeolite usually found in the cavities of oldest basalts. Solid modifications were observed by SEM. The analysis showed the formation of several secondary minerals having a composition compatible with smectites, determined by EDS spectroscopy. All these results allow to test the geochemical modeling in the long term. Further analysis will be needed to reach a full understanding of the weathering of glassy materials. (author)

TAXONOMY AND BIOSTRATIGRAPHIC RECORD OF THE UPPER TRIASSIC CONODONTS OF THE PIZZO MONDELLO SECTION (WESTERN SICILY, ITALY, GSSP CANDIDATE FOR THE BASE OF THE NORIAN

Full Text Available New taxonomic and biostratigraphic investigations on the late Carnian to Rhaetian (Upper Triassic platform conodonts from the Pizzo Mondello section (Western Sicily, Italy, Sicano basin are here presented. Pizzo Mondello is one of the two GSSP candidates for the Carnian/Norian boundary; the section is a 430 m thick continuous succession of upper Carnian to upper Norian marine limestones (Scillato Formation, characterized by uniform facies and high sedimentation rates, and ca. 20 m of Rhaetian white calcilutites (Portella Gebbia limestone. Pizzo Mondello offers one of the most complete conodont records for this time interval in the Tethys. The conodont faunas are characterized by a large variety of species, belonging to the genera Carnepigondolella, Epigondolella, Metapolygnathus, Misikella, Mockina, Neocavitella, Norigondolella, Paragondolella, and Parvigondolella. The richness of the populations allowed a detailed revision and description of all the Upper Triassic species and morphotypes recovered. The revision of the problematic species Carnepigondolella nodosa and "Metapolygnathus communisti B" was thus possible, leading to the establishment of two new species: Carnepigondolella tuvalica n.sp. and Carnepigondolella gulloae n.sp. The latter species would be a good proxy for the Carnian/Norian boundary in the case that the FAD of Halobia austriaca (sample FNP135a will be selected as the primary biomarker for the base of the Norian.

Cross-elaboration of climatic, pedological and vegetational factors allows the water balance of soils to be defined. The data obtained are of particular interest not only for the primary sector, but also for the economy as a whole since the availability of such information is necessary for the correct and rational use of water resources. The application of a methodology, which takes into account the previously mentioned factors, led to the realization of a map showing the overall, annual and monthly water deficit of the soils in Southern Italy, Sicily and Sardinia.

Full Text Available Eastern Sicily is one of the coastal areas most exposed to earthquakes and tsunamis in Italy. The city of Catania that developed between the eastern base of Etna volcano and the Ionian Sea is, together with the neighbour coastal belt, under the strong menace of tsunamis. This paper addresses the estimation of the tsunami hazard for the city of Catania by using the technique of the Worst-case Credible Tsunami Scenario Analysis (WCTSA and is focused on a target area including the Catania harbour and the beach called La Plaia where many human activities develop and many important structures are present. The aim of the work is to provide a detailed tsunami hazard analysis, firstly by building scenarios that are proposed on the basis of tectonic considerations and of the largest historical events that hit the city in the past, and then by combining all the information deriving from single scenarios into a unique aggregated scenario that can be viewed as the worst virtual scenario. Scenarios have been calculated by means of numerical simulations on computational grids of different resolutions, passing from 3 km on a regional scale to 40 m in the target area. La Plaia beach results to be the area most exposed to tsunami inundation, with inland penetration up to hundreds of meters. The harbour turns out to be more exposed to tsunami waves with low frequencies: in particular, it is found that the major contribution to the hazard in the harbour is due to a tsunami from a remote source, which propagates with much longer periods than tsunamis from local sources. This work has been performed in the framework of the EU-funded project SCHEMA.

Morphology and evolution of sulphuric acid caves in South Italy

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

The mercury (Hg) pollution of sediments is the main carrier of Hg for the biota and, subsequently, for the local fish consumers in Augusta Bay area (SE Sicily, Italy), a coastal marine system affected by relevant sewage from an important chlor-alkali factory. This relationship was revealed by the determination of Mass Dependent (MDF) and Mass Independent Fractionation (MIF) of Hg isotopes in sediment, fish and human hair samples. Sediments showed MDF but no MIF, while fish showed MIF, possibly due to photochemical reduction in the water column and depending on the feeding habitat of the species. Benthic and demersal fish exhibited MDF similar to that of sediments in which anthropogenic Hg was deposited, while pelagic organisms evidenced higher MDF and MIF due to photoreduction. Human hair showed high values of δ 202 Hg (offset of +2.2‰ with respect to the consumed fish) and Δ 199 Hg, both associated to fish consumption. - Highlights: • We report the Hg isotope ratios of sediments, fish and human hair in Augusta Bay. • Hg isotopes show mercury transfers from sediments to benthic and demersal fish. • MIF in fish appears to be driven by effect of photoreduction. • MIF in human hair is inherited by fish consumption. - The mercury (Hg) isotope composition of sediments, fish muscles and human hair has been investigated from the highly polluted Augusta Bay (SE Sicily, Italy)

Mount Etna is a composite stratovolcano located along the Ionian coast of eastern Sicily. It is characterized by basaltic eruptions, both effusive and explosive, occurred during a complex eruptive history over the last 500 ka. Flank eruptions occur at an interval of decades, mostly concentrated along the NE, S and W rift zones. A vent clustering at various scales is a common feature in many volcanic settings. In order to identify the clusters within the studied area, a spatial point pattern analysis is undertaken using vent positions, both known and reconstructed. It reveals both clustering and spatial regularity in the Etna region at different distances. The visual inspection of the vent spatial distribution suggests a clustering on the rift zones of Etna volcano. To confirm this evidence, a coarse analysis is performed by the application of Ξ2- and t-test simple statistics. Then, a refined analysis is performed by using the Ripley K-function (Ripley, 1976), whose estimator K(d), knowing the area of the study region and the number of vents, allow us to calculate the distance among two different location of events. The above estimator can be easier transformed by using the Besag L-function (Besag, 1977); the peaks of positive L(d)=[K(d)/π]1/2 -d values indicate clustering while troughs of negative values stand for regularity for their corresponding distances d (L(d)=0 indicates complete spatial randomness). Spatial pattern of flank vents is investigated in order to model the spatial distribution of likely eruptive vents for the next event, basically in terms of relative probabilities. For this, a Gaussian kernel technique is used, and the L(d) function is adopted to generate an optimal smoothing bandwidth based on the clustering behaviour of the Etna volcano. A total of 154 vents (among which 36 are reconstructed), related to Etna flank activity of the last 4.0 ka, is used to model future vent opening. The investigated region covers an area of 850 km2, divided

The purpose of this study was to evaluate how the hydraulic behavior of a horizontal subsurface wetland (HF), that is part of the hybrid wetland (hybrid-TW) of the IKEA® store in Eastern Sicily (Italy), influences the overall wastewater treatment performance. The HF unit experiences frequent overloading peaks due to the extreme variability in the number of visitors at the store, and after 2 years of operation it showed signals of partial clogging at the inlet area. The hydraulics of the HF unit has been monitored through measurements of hydraulic conductivity at saturation (Ks), tracer tests, and geophysical (i.e. electrical resistivity tomography-ERT) measurements carried out during the years 2016 and 2017. Results indicated a general good agreement between the performed measurement techniques, thus their combination, if adequately performed and calibrated, might be a reliable tool for detecting those wetland areas mainly affected by clogging conditions. The results also indicated that partial clogging had no significant effect on the quality of the discharged water. Copyright © 2018 Elsevier B.V. All rights reserved.

A total of 71 loggerhead turtles (Caretta caretta) stranded along the coasts of Sicily (Southern Italy) were examined for non-dioxine like polychlorinated biphenyl (NDL-PCB) levels in muscle and adipose tissue by a gas chromatography-mass spectrometry/mass spectrometry (GC-MS/MS) method. The results revealed 6 high-indicator congener (∑ 6 PCB IND ) levels in 45% of the loggerhead turtles examined, with mean values of 980.39 ± 2508.39 ng/g wet weight in adipose tissue and 102.53 ± 238.58 ng/g wet weight in muscle tissue. The hexachloro and heptachloro PCB congeners were the most abundant in both the sample types. The highest NDL-PCB levels were reached in an adipose tissue sample of a loggerhead turtle of 80 kg stranded along the coasts of Termini Imerese (14 183.85 ng/g wet wt). No significant correlation was found between modified Fulton's K values of the loggerhead turtles and PCB contents (S = 47 151, p > 0.05). Furthermore, no significant differences were found between sexes (W = 365, p >  0.05). The PCB levels found in the present study were much higher than those found in the literature. The present study is the first report on the existence of NDL-PCBs in loggerhead turtles stranded in Sicilian coasts confirming C. caretta as a valuable indicator of contaminant exposure in the marine environment because of their specific biological and ecological characteristics.

Préat, A.; Mamet, B.; Di Stefano, P.; Martire, L.; Kolo, K.

2011-06-01

This article presents a petrographic comparison of the Rosso Ammonitico facies of Western Sicily and the original Rosso Ammonitico Veronese of Northern Italy based on a total of 27 sections. The Rosso Ammonitico has been the subject of numerous controversies that range from bathyal to shallow-water platform sedimentation. Therefore it seemed interesting to verify if the term Rosso Ammonitico has the same geologic connotation from region to region. The Middle-Upper Jurassic Rosso Ammonitico of Western Sicily is a condensed succession formed during a period of extensional synsedimentary tectonics related to the spreading of the Ionian Ocean. Slope-to-basin or pelagic carbonate deposits characterize the sedimentation which consists of reddish mudstones and wackestones. The abundant fauna is composed of radiolarians, protoglobigerinids, Saccocoma, Bositra associated with ammonites. A few ferruginous hardgrounds, Fe-Mn oxide crusts and Mn-coated condensation horizons are also present. The red matrices contain abundant Fe-Mn encrusted, microbored and bioeroded bioclasts. Sporadic Fe-Mn oncolites composed of amorphous Mn-minerals and goethite are also conspicuous. The matrix, as well as the shells and the fillings of the complex associated veinlets, are frequently altered into calcite microsparite. Submicronic iron bacterial and fungal filaments associated with mineralized extracellular polymeric substances (EPS) are observed in the matrix. They record dysaerobic microenvironments at or near the sediment-water interfaces. Early mineralized discontinuities enhanced by subsequent pressure dissolution are reported in the succession. Mn-(Ni) bacterial filaments are exceptionally observed in the cortex of the Fe-Mn oncolites. As a consequence of an early lithification, the Mn filaments are poorly preserved. The pigmentation of the rock is due to the dispersion of submicronic oxyhydroxides (now goethite and amorphous iron) formed by bacterial mediation during early diagenesis

Rainfall-induced shallow landslides are a widespread phenomenon that frequently causes substantial damage to property, as well as numerous casualties. In recent~years a wide range of physically based models have been developed to analyze the triggering process of these events. Specifically, in this paper we propose an approach for the evaluation of different shallow landslide-triggering scenarios by means of the TRIGRS (transient rainfall infiltration and grid-based slope stability) numerical model. For the validation of the model, a back analysis of the landslide event that occurred in the study area (located SW of Messina, northeastern Sicily, Italy) on 1 October 2009 was performed, by using different methods and techniques for the definition of the input parameters. After evaluating the reliability of the model through comparison with the 2009 landslide inventory, different triggering scenarios were defined using rainfall values derived from the rainfall probability curves, reconstructed on the basis of daily and hourly historical rainfall data. The results emphasize how these phenomena are likely to occur in the area, given that even short-duration (1-3 h) rainfall events with a relatively low return period (e.g., 10-20~years) can trigger numerous slope failures. Furthermore, for the same rainfall amount, the daily simulations underestimate the instability conditions. The high susceptibility of this area to shallow landslides is testified by the high number of landslide/flood events that have occurred in the past and are summarized in this paper by means of archival research. Considering the main features of the proposed approach, the authors suggest that this methodology could be applied to different areas, even for the development of landslide early warning systems.

The study aimed to test the reliability of a nutrition questionnaire and to assess potential associations between nutrition knowledge, food consumption and lifestyle behaviours, controlling for sociodemographic factors. Cross-sectional survey. Comprehensive school in the municipality of Butera, a rural area of Sicily, South Italy. The survey was conducted between March and May 2010 on 445 students (4-16 years). All constructs of the questionnaire had statistically significant Cronbach's a and Pearson's correlation coefficients, showing good internal consistency and temporal stability. After controlling for covariates, nutrition knowledge was positively associated with pasta/rice, fish, vegetable and fruit intakes, and negatively with sweets, snacks, fried foods and sugary drinks consumption. Moreover, students whose parents were in the highest educational and occupational categories reported eating significantly more fruits and vegetables and less meat, sweets, snacks, fried foods and sugary drinks. Students with higher nutrition knowledge scores were less likely to have two or more snacks daily and to spend more than 3 h in sedentary activities daily (OR=0.89, 95% CI 0.83, 0.97 and OR=0.92, 95% CI 0.86, 0.99, respectively). High parental education was associated with less frequent snacking and more frequent weekly physical activity, compared with lower categories, whereas high parental occupational category was associated with daily breakfast. Improving nutrition knowledge in children and young adolescents may translate into educating them in good dietary habits. Moreover, nutrition intervention programmes should also involve parents to improve dietary quality and nutritional habits of the entire family.

The aim of this study was to determine and compare the content of 28 elements (Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Rb, Sb, Se, Sr, Tl, U, V and Zn) in fruiting bodies of Boletus aereus Bull. and Clitopilus prunulus P. Kumm collected from eleven unpolluted sites of Sicily (Italy) and, also to relate the abundance of chemical elements in soil with their concentration in mushrooms. Median concentrations of the most abundant elements in Boletus aereus ranged from 31,290 μg/g (K) to 107 μg/g (Zn) in caps and from 24,009 μg/g (K) to 57 μg/g (Zn) in stalks with the following abundance order: K > Na > Ca > Mg > Fe > Al > Rb > Zn. The same elements, in the whole fruiting body of Clitopilus prunulus samples, varied in the range 54,073-92 μg/g following the abundance order: K > Na > Mg > Ca > Fe > Al > Rb > Zn. Metal contents in Boletus aereus and in the whole fruiting body of Clitopilus prunulus, collected from the same sampling sites, showed statistically significant differences for most elements. In particular, Clitopilus prunulus contained around two to four times more Co, Cr, Fe, Mg, Mo, Pb, U and V than caps and stalks of Boletus aereus species which, in turn, was from two to four times more enriched in Cu, Se and Tl. Thus, the elemental content of Boletus aereus and Clitopilus prunulus appeared to be species-dependent. The distribution of chemical elements in Boletus aereus was not uniform throughout the whole fruiting body as most elements were significantly bioconcentrated in caps. Furthermore, the fruit bodies of Boletus aereus from the volcanic soil differed both in major and minor elements concentrations from those collected from sedimentary soils. Cadmium and lead concentrations were below the threshold limits for wild mushrooms proposed by EU Directives (2008 and 2015). The elemental content was not significantly influenced by soil pH.

In education to issues of environmental sustainability and the use of renewable energy resources, there are the existing laboratory teaching methodologies in Superior School "A. Volta" in Palermo (Italy) for acquisition, processing and control network of agro-meteorological data on the local area. This station was planned to allow students practical multidisciplinary learning experiences in the field of agro-meteorological applications. The School started a few months ago a project of MIUR (Italian Ministry of Education) that updates the lab through the most innovative digital technologies in the field of mechatronics, domotic and sustainable energy, that are supported by the latest needs of scientific-educational multimedia. It is an educational training that intends to implement a data collection center agro-meteorological on "digital platforms," informational purposes and applications, on current issues of climate changes and their consequences in Sicily (Italy). This active learning will interconnect the data collected from the station weather and climate of the school with those locally and regionally, with "weather-climatic patterns" correlations that are implemented in the Mediterranean area (International Program "GAW-Global Atmosphere Watch"). For this reason were enabled synergies with two major public scientific research and acquisition services-data disclosure (ENEA and SIAS-Agrometeorological Information Service, Sicily Region), both to energy efficiency of the School Station, both to support data and digital applications in GIS, with agro-meteorological services to companies operating in the agricultural and environmental sustainability, high consideration themes in European Programming. A branch of this training course is the entrepreneurship education, carried out by a few years in School with the development of "experimental models" for the creation of "innovation clusters" to make entrepreneurial experience since school, creating/managing mini

Off East Sicily (at 2100 m depth, 25 km off the harbour of Catania) a prototype of a cabled deep-sea observatory (NEMO-SN1) was set up and has been operational in real-time since 2005 (the cabled deep-sea multi-parameter station SN1, equipped with geophysical and environmental sensors and the cabled NEMO-OνDE, equipped with 4 broadband hydrophones). The Western Ionian Sea is one of the node sites for the upcoming European permanent underwater network (EMSO). Within the activities of the EC project ESONET-NoE some demonstration missions have been funded. The LIDO-DM (Listening to the Deep Ocean-Demonstration Mission) is one of these and is related to two sites, East Sicily and Iberian Margin (Gulf of Cadiz), the main aims being geo-hazards monitoring and warning (seismic, tsunami, and volcanic) and bio-acoustics. The LIDO-DM East Sicily installation represents a further major step within ESONET-NoE, resulting in a fully integrated system for multidisciplinary deep-sea science, capable to transmit and distribute data in real time to the scientific community and to the general public. LIDO-DM East Sicily hosts a large number of sensors aimed at monitoring and studying oceanographic and environmental parameters (by means of CTD, ADCP, 3-C single point current meter, turbidity meter), geophysical phenomena (low frequency hydrophones, accelerometer, gravity meter, vector and scalar magnetometers, seismometer, absolute and differential pressure gauges), ocean noise monitoring and identification and tracking of biological acoustic sources in deep sea. The latter will be performed using two tetrahedral arrays of 4 hydrophones, located at a relative distance of about 5 km, and at about 25 km from the shore. The whole system will be connected and powered from shore, by means of the electro-optical cable net installed at the East Sicily Site Infrastructure, and synchronised with GPS. Sensors data sampling is performed underwater and transmitted via optical fibre link, with

High-resolution and up-to-date topographic data are of high value in volcanology and can be used in a variety of applications such as volcanic flow modeling or hazard assessment. Furthermore, time-series of topographic data can provide valuable insights into the dynamics of an ongoing eruption. Differencing topographic data acquired at different times enables to derive areal coverage of lava, flow volumes, and lava extrusion rates, the most important parameters during ongoing eruptions for estimating hazard potential, yet most difficult to determine. Anyhow, topographic data acquisition and provision is a challenge. Very often, high-resolution data only exists within a small spatial extension, or the available data is already outdated when the final product is provided. This is especially true for very dynamic landscapes, such as volcanoes. The bistatic TanDEM-X radar satellite mission enables for the first time to generate up-to-date and high-resolution digital elevation models (DEMs) repeatedly using the interferometric phase. The repeated acquisition of TanDEM-X data facilitates the generation of a time-series of DEMs. Differencing DEMs generated from bistatic TanDEM-X data over time can contribute to monitor topographic changes at active volcanoes, and can help to estimate magmatic ascent rates. Here, we use the bistatic TanDEM-X data to investigate the activity of Etna volcano in Sicily, Italy. Etna's activity is characterized by lava fountains and lava flows with ash plumes from four major summit crater areas. Especially the newest crater, the New South East Crater (NSEC) that was formed in 2011 has been highly active in recent years. Over one hundred bistatic TanDEM-X data pairs were acquired between January 2011 and March 2017 in StripMap mode, covering episodes of lava fountaining and lava flow emplacement at Etna's NSEC and its surrounding area. Generating DEMs of every bistatic data pair enables us to assess areal extension of the lava flows, to

The general increase of the cultivation and trade of Bt transgenic plants resistant to Lepidoptera pests raises concerns regarding the conservation of animal and plant biodiversity. Demand for biofuels has increased the cultivation and importation of oilseed rape (Brassica napus L.), including transgenic lines. In environmental risk assessments (ERAs) for its potential future cultivation as well as for food and feed uses, the impact on wild Brassicaeae relatives and on non-target Lepidoptera should be assessed. Here we consider the potential exposure of butterflies as results of possible cultivation or naturalization of spilled seed in Sicily (Italy). Diurnal Lepidoptera, which are pollinators, can be exposed directly to the insecticidal proteins as larvae (mainly of Pieridae) through the host and through the pollen that can deposit on other host plants. Adults can be exposed via pollen and nectar. The flight periods of butterflies were recorded, and they were found to overlap for about 90% of the flowering period of B. napus for the majority of the species. In addition, B. napus has a high potential to hybridise with endemic taxa belonging to the B. oleracea group. This could lead to an exposure of non-target Lepidoptera if introgression of the Bt gene into a wild population happens. A rank of the risk for butterflies and wild relatives of oilseed rape is given. We conclude that, in environmental risk assessments, attention should be paid to plant-insect interaction especially in a biodiversity hotspot such as Sicily. © 2018 Institute of Zoology, Chinese Academy of Sciences.

This paper illustrates the results of a study carried out in four Regional Parks of Sicily (Italy), concerning traditional knowledge on food use of wild plant species. The main aims of the paper were: (i) to verify which wild plant species are used for food purpose in the local culture based on information provided by elderly inhabitants (ii) to verify the presence of wild plant species which have not been cited for food use in previous studies in the Mediterranean area (iii) to determine how many of the most frequently cited wild plant species are cultivated by the local population in the four Sicilian Parks. Semi-structured interviews were carried out in the local communities of the four Regional Parks between 2007 and 2010. A total of 802 people over the age of 60 were interviewed. Cultural Importance Index was used to evaluate the level of importance given to any wild plant species as a food in the local culture. The level of appreciation of the wild plant species and the possible effects of wild plants on human health were also investigated. Local communities currently use a total number of 119 wild species for food purposes. Asteraceae and Brassicaceae were the most represented botanical families. In each of the four Sicilian Parks, Cichorium intybus L. and Foeniculum vulgare Mill. obtained the highest Cultural Importance Index values. Sixty-four species were indicated as also having medicinal properties. Leaves and other aerial plant parts were the parts most-used for the preparation of traditional recipes. The research shows that the level of traditional knowledge on the food uses of wild plant species in the study area is poor. The food uses of plants which are most likely to survive over time are those at the interface of food and medicine. Further agronomic studies are needed for a number of species with a view to introducing them as a crop into non-intensive agricultural systems.

2008-07-01

Full Text Available An unusual virus-like yellow leaf disorder associated with fruit marbling was observed during the winter of 2005 in some greenhouse tomato crops in the province of Ragusa Sicily (Southern Italy. Leaf samples from 250 symptomatic tomato plants were serologically tested by DAS-ELISA technique for 5 viruses: Tomato spotted wilt virus (TSWV, Impatiens necrotic spot virus (INSV, Tobacco mosaic virus (TMV, Cucumber mosaic virus (CMV and Pepino mosaic virus (PepMV. PepMV was detected in 215 of the samples. The virus was mechanically transmitted to cucumber, wild metel, wild tobacco and ‘Rio Grande’ tomato. The experimental host range of PepMV-Ragusa differed from that of the PepMV found in Sardinia in 2001, which infected ‘Camone’ tomato. By applying RT-PCR to 25 PepMV-infected tomato plants, the expected 844 bp DNA fragment for PepMV and the expected 439 bp DNA fragment for Tomato chlororis virus (ToCV were obtained from all the samples tested. Sequences of the obtained amplicons were used to study the phylogenetic relationships of the viruses with isolates from other countries. Nucleotide sequence alignments showed that the sequence CP-PepMV-Ragusa (Genbank acc. No. DQ 517884 were 99% homologous with both US2 and Spain-Murcia isolates, while those of ToCV-Ragusa (Genbank acc. No. DQ517885 isolate HSP70, were 99% homologous with the Florida isolate, and 98% with the Lebanon isolate. The results proved that the unusual disorder found in greenhouse tomatoes in Sicily can be associated with infections by PepMV and ToCV, reported for the first time in a mixed infection.

Water Quality and Soil Natural Salinity in the Southern Imera Basin (Sicily, Italy

Full Text Available The Southern Imera river crosses one of the most arid part of Sicily. The geochemical composition of the river water is due to the solubilization processes of gypsum rocks, which accounts for the particularly low quality of resources in the areas in which the presence of evaporitics deposits is highest. The geochemical composition and hydraulic parameters of river was monitored with the aim of reaching a better understanding of the relationships between litology and water quality. The Imera river is a potential local hydric resource, but seasonal variability of salinity does not allow farmers to use its water. A geochemical monitoring of the Imera river water has been carried out in selected localities integrating a GIS analysis of the river hydrography basin and of the distribution of the evaporitic formation. During 2003 and 2005 we performed four monitoring surveys of water chemicophysical parameters (temperature, pH and electrical conductivity and of the main ionic concentrations (Ca2+, Mg2+, K+, Na+, Cl-, SO4 2- . We also installed a multiparameter probe next to the hydrometrical station of Drasi, about 15 km from the river mouth. Such multiparameter probe was used to determine, continuously and simultaneously, temperature, electrical conductivity, pH, dissolved oxygen, redox potenzial, water level. The geochemical composition of the water allowed to confirm the results of Roda (1971 and Favara (2000, who pointed out that the main cause of degrade of the Southern Imera river are the salt-rich waters of some tributaries flowing over gypsum rocks and halite deposits. We have been able to identify which specific areas are the main contributors to the degradation of the Imera river.

Pioneering research on "Mediterranean Kala-Azar" carried out by Adler and Theodor early in the past century (~1930s) had identified Catania city (Sicily) as a major focus of the disease nowadays known as zoonotic visceral leishmaniasis (VL). Despite the fact that disease in both humans and dogs has continued to be highly prevalent in the Catania province up to the present times, research on Leishmania vectors in this urban focus dates back to that distant period. This study aimed to evaluate the persistence and current composition of the sand fly fauna in urban environments of Catania in recent years, 2006 and 2013. In 2006 fifty-one suitable collecting sites were identified within 44 sub-units of a grid drawn to include the urban Catania area. In 2013 the survey was restricted to four of the most productive and representative sites resulting from the 2006 survey. In both periods 3 collections per month were performed using standard sticky traps set for 3 days in wall holes/cavities along public roads, from the end of April through December. 43/51 sites (84.3%) were found positive for sand flies. The 2006 collections accounted for a total of 4341 specimens including six species. Among competent Leishmania vector species, P. perniciosus was the most prevalent (36.5%) being identified in all sand fly-positive sites, with significant abundance in those of the old city centre. Other species of interest were P. sergenti (2.5%) and P. neglectus (1.5%). The 2013 survey produced 1130 sand flies, of which 39.5% were P. perniciosus, 1.6% P. sergenti and 0.7% P. neglectus. A search for Leishmania DNA in a small sample of 72 P. perniciosus females revealed 11% infection prevalence. Our findings from an old urban focus of leishmaniasis demonstrate that phlebotomine sand flies have adapted fairly well to the drastic environmental changes that have occurred in cities of the Western world in the past century and still represent a potential risk for Leishmania transmission.

Inhalation of radon (Rn-222) and its progeny is one of the most significant sources of natural radiation exposure of the population. Nowadays, high radon exposures have been shown to cause lung cancer and many governments all over the world have therefore recommended that radon exposures in dwellings and indoor workplaces should be limited. Radon levels in buildings vary widely from area to area depending on local geology. This paper presents the results of a long-term survey of radon concentrations carried out from 2005 till 2010 in schools and dwellings of Eastern Sicily, using the solid-state nuclear track detector (SSNTD) technique. The investigated area shows medium-high indoor radon concentrations, higher than the Italian average of about 70 Bq/m 3 , with peaks of 500 Bq/m 3 or more in buildings near active faults. Fortunately, only a small fraction of the measurements, about 1.5% of total, was found greater than EU and Italian action limits for indoor and workplaces. - Highlights: ► In this paper we report radon monitoring survey carried out in the east Sicily in schools and dwellings. ► The detection methodology was the solid-state nuclear track detector one. ► The work was supported by a national projects financed by the National Institute of Nuclear Physics.

FACIES PARTITIONING AND SEQUENCE STRATIGRAPHY OF A MIXED SILICICLASTIC-CARBONATE RAMP STACK IN THE GELASIAN OF SICILY (S ITALY: A POTENTIAL MODEL FOR ICEHOUSE, DISTALLY-STEEPENED HETEROZOAN RAMPS

Directory of Open Access Journals (Sweden)

FRANCESCO MASSARI

2012-11-01

Full Text Available The Gelasian succession of the Capodarso area (Enna-Caltanissetta basin, Sicily, Italy consists of an offlapping stack of cycles composed of siliciclastic units passing to carbonate heterozoan, clino-stratified wedges, developed from a growing positive tectonic structure. Identification of a number of facies tracts, based on sedimentary facies, biofacies and taphofacies, provided important information about the differentiation and characterisation of systems tracts and key stratal surfaces of sequence stratigraphy. The bulk of carbonate wedges are interpreted as representing the rapid falling-stage progradation of distally steepened ramps. The inferred highest rate of carbonate production during forced regressions was concomitant with active downramp resedimentation by storm-driven downwelling flows, leading to storing of most carbonate sediment on the ramp slope as clino-beds of the prograding bodies. Comparison of the Capodarso ramps with other icehouse carbonate ramps, with particular regard to the Mediterranean Plio-Pleistocene, provides clues for defining some common features. These are inferred to include: (1 brief, rapid episodes of progradation concomitant with orbitally-forced sea-level changes, resulting in limited ramp width; (2 preferential fostering of growth and downramp resedimentation of heterozoan carbonates during glacial hemicycles marked by enhanced atmospheric and marine circulation; (3 building out from positive features of entirely submerged distally-steepened ramps with storm-wave-graded profile and distinctive clinoforms; (4 ramp stacks generally consisting of mixed clastic-carbonate sequences showing an ordered spectrum of distinct frequencies; (5 rapid, continuous changes in environmental parameters, leading to the short-lived persistence of faunal communities, climax communities generally having insufficient time to form.

A 20 year coastal altimetry data set (X-TRACK) is used, for the first time, to gain insight into the long-term interannual variations of the surface circulation in the Sicily Channel. First, a spectral along with a time/space diagram analysis are applied to the monthly means. They reveal a regionally coherent current patterns from track to track with a marked interannual variability that is unequally shared between the Atlantic Tunisian Current and Atlantic Ionian Stream inflows in the Sicily Channel and the Bifurcation Tyrrhenian Current outflow northeast of Sicily. Second, an empirical altimetry-based transport-like technique is proposed to quantify volume budgets inside the closed boxes formed by the crossing of the altimetry tracks and coastlines over the study area. A set of hydrographic measurements is used to validate the method. The inferred altimetry transports give a well-balanced mean eastward Atlantic Waters baroclinic flow of 0.4 Sv and standard deviations of 0.2 Sv on a yearly basis throughout the Sicily Channel and toward the Ionian Sea, which is fairly coherent with those found in the literature. Furthermore, the analysis allows to quantify the intrusions of Atlantic Waters over the Tunisian Shelf (0.12 ± 0.1 Sv) and highlights two main modes of variability of the main surface waters path over the Sicily Channel through the Bifurcation Atlantic Tunisian Current and Atlantic Ionian Stream systems. Some physical mechanisms are finally discussed with regards to changes in the observed currents and transports.

FIRST RECORD OF ICHTHYOSAURS IN SICILY(UPPER TRIASSIC OF MONTE SCALPELLO, CATANIA PROVINCE

Full Text Available Here we report for the first time on the presence of ichthyosaurs in Sicily, southern Italy. The deposit of origin (Mufara Formation can be dated to the upper Carnian (Tuvalian substage based on a typical association of ammonites, one of which (Shastites sp. is embedded in the sediment still encrusting one of the bone specimens recently found. The latter consist of two isolated vertebral centra that are referred to the Ichthyosauria thanks to their disk-like shape (i.e. they are much taller than long combined with the amphicelous condition, lack of transverse processes, and presence of rib articulations on the central sides. The largest specimen is more precisely an anterior dorsal vertebra from an adult individual, ascribed to Shastasauridae indet. By the presence of elongated reniform diapophyseal facets, cranially not truncated, and absence of parapophyses. The smaller specimen represents an anterior cervical element from an immature individual of a likely smaller-sized, indeterminate taxon. These finds indicate that the biodiversity of the Monte Scalpello Triassic fauna is higher than previously known, but above all represent the southernmost occurrence of Triassic ichthyosaurs in the western Tethys basin.

This study aims at evaluating the performance of the Maximum Entropy method in assessing landslide susceptibility, exploiting topographic and multispectral remote sensing predictors. We selected the catchment of the Giampilieri stream, which is located in the north-eastern sector of Sicily (southern Italy), as test site. On 1/10/2009, a storm rainfall triggered in this area hundreds of debris flow/avalanche phenomena causing extensive economical damage and loss of life. Within this area a presence-only-based statistical method was applied to obtain susceptibility models capable of distinguish future activation sites of debris flow and debris slide, which where the main source failure mechanisms for flow or avalanche type propagation. The set of predictors used in this experiment comprised primary and secondary topographic attributes, derived by processing a high resolution digital elevation model, CORINE land cover data and a set of vegetation and mineral indices obtained by processing multispectral ASTER images. All the selected data sources are dated before the disaster. A spatially random partition technique was adopted for validation, generating fifty replicates for each of the two considered movement typologies in order to assess accuracy, precision and reliability of the models. The debris slide and debris flow susceptibility models produced high performances with the first type being the best fitted. The evaluation of the probability estimates around the mean value for each mapped pixel shows an inverted relation, with the most robust models corresponding to the debris flows. With respect to the role of each predictor within the modelling phase, debris flows appeared to be primarily controlled by topographic attributes whilst the debris slides were better explained by remotely sensed derived indices, particularly by the occurrence of previous wildfires across the slope. The overall excellent performances of the two models suggest promising perspectives for

A spatially random partition technique was adopted for validation, generating fifty replicates for each of the two considered movement typologies in order to assess accuracy, precision and reliability of the models. The debris slide and debris flow susceptibility models produced high performances with the first type being the best fitted. The evaluation of the probability estimates around the mean value for each mapped pixel shows an inverted relation, with the most robust models corresponding to the debris flows. With respect to the role of each predictor within the modelling phase, debris flows appeared to be primarily controlled by topographic attributes whilst the debris slides were better explained by remotely sensed derived indices, particularly by the occurrence of previous wildfires across the slope. The overall excellent performances of the two models suggest promising perspectives for

This study aims at comparing the performances of a presence only approach, namely Maximum Entropy, in assessing landslide triggering-thickness susceptibility within the Mili catchment, located in the north-eastern Sicily, Italy. This catchment has been recently exposed to three main meteorological extreme events, resulting in the activation of multiple fast landslides, which occurred on the 1st October 2009, 10th March 2010 and 1st March 2011. Differently from the 2009 event, which only marginally hit the catchment, the 2010 and 2011 storms fully involved the area of the Mili catchment. Detailed field data was collected to associate the thickness of mobilised materials at the triggering zone to each mass movement within the catchment. This information has been used to model the landslide susceptibility for two classes of processes clustered into shallow failures for maximum depths of 0.5m and deep ones in case of values equal or greater than 0.5m. As the authors believed that the peculiar geomorphometry of this narrow and steep catchment played a fundamental role in generating two distinct patterns of landslide thicknesses during the initiation phase, a HRDEM was used to extract topographic attributes to express near-triggering geomorphological conditions. On the other hand, medium resolution vegetation indexes derived from ASTER scenes were used as explanatory variables pertaining to a wider spatial neighbourhood, whilst a revised geological map, the land use from CORINE and a tectonic map were used to convey an even wider area connected to the slope instability. The choice of a presence-only approach allowed to effectively discriminate between the two types of landslide thicknesses at the triggering zone, producing outstanding prediction skills associated with relatively low variances across a set of 20 randomly generated replicates. The validation phase produced indeed average AUC values of 0.91 with a standard deviation of 0.03 for both the modelled landslide

The hourly average wind speed data recorded by CNMCA (Centro Nazionale di Meteorologia e Climatologia Aeronautica) have been used to study the statistical properties of the wind speed at nine locations on Sicily. By grouping the observations month by month, we show that the hourly average wind speed, with calms omitted, is represented by a Weibull function. The suitability of the distribution is judged by the discrepancies between the observed and calculated values of the monthly average wind speed and of the standard deviation. (Author)

Exploring the submarine Graham Bank in the Sicily Channel

Full Text Available In the Sicily Channel, volcanic activity has been concentrated mainly on the Pantelleria and Linosa islands, while minor submarine volcanism took place in the Adventure, Graham and Nameless banks. The volcanic activity spanned mostly during Plio-Pleistocene, however, historical submarine eruptions occurred in 1831 on the Graham Bank and in 1891 offshore Pantelleria Island. On the Graham Bank, 25 miles SW of Sciacca, the 1831 eruption formed the short-lived Ferdinandea Island that represents the only Italian volcano active in historical times currently almost completely unknown and not yet monitored. Moreover, most of the Sicily Channel seismicity is concentrated along a broad NS belt extending from the Graham Bank to Lampedusa Island. In 2012, the Istituto Nazionale di Geofisica e Vulcanologia (INGV carried out a multidisciplinary oceanographic cruise, named “Ferdinandea 2012”, the preliminary results of which represent the aim of this paper. The cruise goal was the mapping of the morpho-structural features of some submarine volcanic centres located in the northwestern side of the Sicily Channel and the temporary recording of their seismic and degassing activity. During the cruise, three OBS/Hs (ocean bottom seismometer with hydrophone were deployed near the Graham, Nerita and Terribile submarine banks. During the following 9 months they have recorded several seismo-acoustic signals produced by both tectonic and volcanic sources. A high-resolution bathymetric survey was achieved on the Graham Bank and on the surrounding submarine volcanic centres. A widespread and voluminous gas bubbles emission was observed by both multibeam sonar echoes and a ROV (remotely operated vehicle along the NW side of the Graham Bank, where gas and seafloor samples were also collected.

Full Text Available This study examines the ways in which residents in the United States perceive Sicily as a tourist destination based on representations of the island encountered through commercial cinema. Twelve participants viewed trailers or clips of twelve feature films and then rated their impressions of the people, places, activities, and moods of each piece. They then responded to an open-ended question about whether what they saw made them want to go to Sicily. Next, I reviewed each participant’s responses with them to investigate their perceptions further. I mix the findings of this process with insights gleaned from the literature on film-induced tourism as well as from analyses of the films themselves.

Full Text Available Molecular epidemiology of influenza B virus remained poorly studied in Italy, despite representing a major contributor to seasonal epidemics. This study aimed to reconstruct the phylogenetic relationships and genetic diversity of the hemagglutinin gene sequences of 197 influenza B strains circulating in both Southern (Sicily and Northern (Liguria Italy between 2010 and 2015. Upper respiratory tract specimens of patients displaying symptoms of influenza-like illness were screened by real-time RT-PCR assay for the presence of influenza B virus. PCR-positive influenza B samples were further analyzed by sequencing. Neighbor-joining phylogenetic trees were constructed and the amino-acid alignments were analyzed. Phylogenetic analysis showed clusters in B/Victoria clade 1A/1B (n = 29, 14.7%, and B/Yamagata clades 2 (n = 112, 56.8% and 3 (n = 56, 28.4%. Both influenza B lineages were found to co-circulate during the study period, although a lineage swap from B/Victoria to B/Yamagata occurred in Italy between January 2011 and January 2013. The most represented amino-acid substitutions were N116K in the 120-loop (83.9% of B/Yamagata clade 3 strains and I146V in the 150-loop (89.6% of B/Victoria clade 1 strains. D197N in 190-helix was found in almost all viruses collected. Our findings provide further evidence to support the adoption of quadrivalent influenza vaccines in our country.

Isolation of Enterobacter sakazakii from ass' milk in Sicily: case report, safety and legal issues.

Enterobacter sakazakii (Es) infections are likely to involve newborns and infants, causing meningitis and necrotizing enterocolitis and sepsis. Contamination of infant formulae milk during factory production or bottle preparation is implicated. Es has been isolated from environmental sources and from food other than infant formula and milk powder, but why it is associated only with the consumption of infant formulae, is unclear. According to Regulation (EC) No. 2073/2005 on the microbiological criteria for foodstuffs, Es is considered a microorganisms of greatest concern in infant formulae and follow-on formulae. Es is included between "safety criteria". The isolation of two strains of Es from 50 samples of ass' milk in Sicily is described. The antibiotic resistance profile of the isolates revealed a multiple resistance profile, including fluoroquinolones, commonly used to treat the infections. The authors underline the importance of survey because in Italy ass' milk is considered one of the solutions for infants suffering from hypersensitivity to milk protein of some animal species. There is scarce information about the ecology and the uncertainty concerning the source of infection in the children and adults; the authors are concerned that ass' milk could become a high-risk food.

The employment of time-of-flight (TOF) neutron diffraction allowed for the quantitative determination of mineral phase contents of the ceramic bulk of several pottery fragments coming from Milazzo and Messina (Sicily, southern Italy). From an historical-artistic point of view, all the samples were dated back to the 12th to 13th centuries AD and classified as belonging to the 'proto-majolica' ceramic class. The adopted procedure is absolutely non-destructive, so that measurements were performed on the entire fragments without any sampling. The information derived, by applying the Rietveld analysis method, allowed us to formulate hypotheses concerning the fabrication processes of the artefacts.

This paper presents the results of an assessment of public views on eventual geothermal energy development in Sicily. The research was carried out under a much wider research project, VIGOR, with the aim to explore the feasibility of geothermal energy utilization in southern Italy. This study has two primary objectives: (1) to explore the views and opinions of local communities regarding the potential of geothermal energy applications; (2) to contribute to the growing literature on public engagement with energy issues. In order to explore public views towards geothermal technologies, we conducted a case study using both qualitative and quantitative methods. Although Italy has enormous geological potential for geothermal energy production, levels of knowledge of this energy source amongst the public are low. The results indicate that the issue is shrouded in uncertainty and that the Sicilian public expresses a diffused lack of trust in decision-making processes. Taken together, these factors are likely to strongly impact eventual further developments in this sector. The results clearly show the need for further societal dialogue supported by a sound communication action strategy as the first stage in a public participation

Present-day stress magnitude at depth from leak-off tests in Italy

2012-04-01

We present new results from the analysis of leak-off tests, performed in deep oil wells in Italy, to characterize the present-day stress magnitude and regime in the crust. In the last years we have collected a large number of data (more than 500) from different stress indicators, mainly borehole breakouts, earthquake focal mechanisms and fault data, which provided information on the present-day stress orientations. In some areas the tectonic regime has been inferred either from fault plane solutions of M≥4 earthquakes or from stress inversions of smaller earthquakes. Where seismicity lacks, the regime is not well constrained and little or no information on the magnitude of the crustal stresses is available. In order to improve our knowledge in stress regime and its magnitude in Italy, in this work we use the leak-off test technique. Each test is performed at the bottom of an open hole by sealing off a section and then slowly pressurizing with a fluid until hydraulic tensile fractures develop. The minimum horizontal stress is inferred by leak-off pressure record, the vertical stress is computed by rock density data and the maximum horizontal stress is estimated applying a specific formula from the literature. Thanks to ENI S.p.A. (Italian oil company), that kindly provided new well data, we have been able to perform a critical review of our preliminary calculations and to enhance our previous results concerning stress magnitudes. Totally, we have analyzed 192 leak-off tests at depth between 200 and 5400m (average 1800m). In particular, wells are located along the Italian peninsula and in Sicily: most of them are in the Po Plain and along the Apenninic foredeep; few are in southern Apenninic belt and a few tens are in Sicily. After an accurate selection of the most robust results, we better characterize the Italian stress regime at depth.

Mediterranean soils are an important key to understanding past volcanic events and landscape evolution. The influence and timing of Quaternary volcanic events on soils, however, remains still poorly understood in southern Italy. We used a multi-method approach to explore the origin and age of volcanic deposits (soils) in Sicily and Calabria. By comparing the geochemical signature of the soils with the chemical fingerprint of magmatic effusive rocks in southern Italy, we tried to identify the source material. It seems that the investigated soils on the Nebrodi (Sicily) and Sila (Calabria) mountains were both influenced by volcanic deposits having a high-K calc-alkaline series volcanic background. The Aeolian islands (Lipari and Vulcano) are the most likely sources of origin. Due to weathering processes of the volcanic sediments and the partial mixing with the underlying non-volcanic parent material, a direct relation with the potential source areas was not always straightforward. Immobile elements and their corresponding ratios (e.g. the Nb/Y vs Zr/Ti plot) or trace elements (Co, Th) and rare earth elements gave better hints of the origin of the deposits. Radiocarbon dating of the stable soil organic fraction (H2O2 resistant) indicated a minimum age of 8 - 10 ka of the Nebrodi and Sila soils. The chemical proxy of alteration (CPA) and weathering index according to Parker (WIP) were tested as proxies for an age estimate of the volcanic deposits and duration of soil formation. The soils and, subsequently, landscape are characterized by multiple volcanic depositional phases for the last 30 - 50 ka in the Sila mountains and about 70 ka in the Nebrodi mountains. We show that a multi-method approach (numerical dating, relative dating using weathering indices and the forensic procedure) enabled the identification of potential source areas, gave tentative age estimates of the ash deposits, duration of soil formation and, therefore, improved our understanding of volcanic

Full Text Available The persistence of crustacean populations in ephemeral ponds requires appropriate adaptations in life history strategies (e.g. in hatching phenology. Organisms take advantage of pond filling when it occurs and hedge their bets for the possibility to complete one or more life cycles or to produce resting stages that ensure that the population will not go extinct. We carried out laboratory experiments to investigate the dynamics of a sexual population of Heterocypris barbara from a vernal pool in Lampedusa Island (Sicily. Experimental organisms were obtained hydrating sediments from Aria Rossa temporary pond. Recruitment from resting eggs, voltinism, mean body size and sex ratio were observed in microcosms at different conductivities (high 2.0-2.7 mS cm-1, intermediate 1.0-1.1 mS cm-1 and low 0.5-0.6 mS cm-1. Microcosms were kept in laboratory controlled conditions: constant (24°C 12:12 L:D and 16°C 10:14 L:D photoperiod or fluctuating thermal regimes. The experiment lasted 7 months. Resting and non-resting egg production and up to a bivoltine life cycle were observed. Recruitment events from egg bank and voltinism varied by thermal regime and conductivity. A prolonged recruitment phase occurred in conditions that could be considered a proxy of a rainy season (16°C, 10:14 L:D and low conductivity or of long hydroperiods (spring thermal fluctuating regime and intermediate conductivity. At 24°C, age at reproduction of females from resting eggs almost doubled at low conductivity (in comparison with high conductivity. Low conductivity also reduced hatching time of resting eggs while it increased development time and age at maturity. In thermal fluctuating regime, degree-days to reproduction were about double than at constant 24°C. Males, observed in all microcosms, reached maturity faster and had a shorter life span than females. Males initially outnumbered females, but later in the experiments females became dominant. We also evaluated the

A comparison of medicinal plant use in Sardinia and Sicily-De Materia Medica revisited?

Written records of oral medical traditions have had significant impact on the development of medicine and the pharmacopoeias. Modern ethnobotanical studies in Europe and the Mediterranean region, however, have so far largely overlooked the richness and accuracy of historic sources and ignored their probable influence on the development of today's local traditional medicines. Here, we explore the common fundament of traditional knowledge for the medicinal plant uses in Sardinia and Sicily by comparing the selection of medicinal species and specific uses with those of Dioscorides' De Materia Medica. We use (i) a quantification of citations for medicinal species mentioned in ethnobotanical studies conducted in Sardinia and Sicily (ii) a comparison of the flora and medicinal flora with a chi(2)-test (iii) a binomial approach recently introduced into ethnobotany (iv) a comparison of the most frequently used species with the indications cited in Dioscorides' De Materia Medica (v) and a crosscheck of all mentioned species with their appearance in Berendes' translation of De Materia Medica. We identified a core group of 170 medicinal species used on either islands, which accumulate 74% of all citations and are best represented in De Materia Medica. The 15 most frequently used species of both islands demonstrate intriguing parallels for indications with Dioscorides' work. The ethnopharmacopoeia of Sicily and Sardinia are shallow stereotypes of the different editions of De Materia Medica and talking of oral tradition in this respect is a contradiction. The medicinal species of Sardinia and Sicily are largely widespread and common species, including many weeds, which are not facing threat of extinction. Therefore, using traditional medicinal practices as an argument for conservation biology or vice versa is not scientifically sound.

Environmental concentrations of fibers with fluoro-edenitic composition and population exposure in Biancavilla (Sicily, Italy

Full Text Available INTRODUCTION. The town of Biancavilla (Sicily was included in the National Priorities List of Contaminated Sites due to environmental dispersion of amphibole fibers owing to the extraction of materials from a local quarry. The present report summarizes results from several, hitherto unpublished, environmental surveys carried out in the area, as well as from published analyses of the chemistry and composition of fibers. METHODS. Data included here comprises environmental fiber concentrations by scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS analysis in soil, indoor and outdoor air, personal monitoring, as well as a chemical characterization of the fibers. The full chemical structure and spectroscopic characterization of fibers were obtained through a multi-analytical approach: SEM-EDS, X-ray powder diffraction (XRPD, as well as Mössbauer (MS and Fourier transform infrared (FT-IR spectroscopies. RESULTS. Data analyzed provided a spatial and temporal picture of fiber concentrations in Biancavilla, and a qualitative assessment of population exposure. Results suggest that until 2000, the population had been exposed to high levels of amphibole fibers. Mitigation measures adopted since 2001, gradually reduced exposure levels to about 0.10.4 ff/l. Previous studies on fibrous amphiboles from Biancavilla reported considerable chemical variability. Differences in composition, especially concerning the presence of Si, Ca, Fe, and Na, were found both within and between samples. Compared to the previously investigated prismatic fluoro-edenite, these fibrous fluorine amphiboles consistently showed higher average values of Si and Fe content, whereas Ca was significantly lower, which we consider a distinctive characteristic of the fluorine fibrous variety. CONCLUSIONS. The population of Biancavilla had been highly exposed to a suite of fibrous amphiboles for over 50 years. Dust mitigation measures have gradually reduced exposure, but

Geochemistry and habitat of oils in Italy

Novelli, L.; Mattavelli, L.

Most of the onshore and offshore oil occurrences found in Italy have been systematically analyzed by different techniques, i.e., capillary gas chromatography, biological markers, and stable isotopes composition. On the basis of the above analyses, ten different groups of oil have been identified and geographically located. Subsequently, the influence of the various geological settings on generation and migration of these different groups of oils was investigated and is discussed here. In a foredeep regime, the remarkably fast heating rates, due to the rapid burial during late Tertiary, caused a rapid generation of oil mainly in the Triassic carbonate source rocks. Such generation, combined with the high over-burden pressure and a contemporaneous development of an intense tectonic compression, resulted in the expulsion of immature, heavy oils. Examples of this are evident in the central Adriatic Sea, southern Italy, and southeastern Sicily. Due to its complex geological and tectonic history, the Alpine-Apennine chain behaved differently with regard to oil generation and migration in different areas. In fact, the high temperatures reached by the Mesozoic source rocks underneath a stack of allochthonous thrust sheets and the insulating thermal blanket effect exerted by the same sheets on other younger source rocks above gave rise to generally light oils. Furthermore, in this unique geological setting, the most external thrust sheets locally acted as reservoirs of the foredeep regime. Foreland sequences acted as both reservoirs of the foredeep oils and as generative kitchens of liquid hydrocarbons if suitable source rocks were present and adequate burial was reached.

The dynamic interaction of endogenic and exogenic processes in active geodynamic context leads to the deterioration of the physico-mechanical characteristics of the rocks, inducing slopes instability. In such context, the morphometric parameters and the analysis of landslide distribution contribute to appraise the evolutive state of hydrographic basins. The aim of the study is the morphometric characterization of the Roccella Torrent basin (Rtb) located in South Italy. Landsliding and tectonic structure dynamically interact with the drainage pattern that records these effects and permits the definition of the evolutive geomorphic stage of the basin. The Air Photograph Investigation and field surveys permitted to draw the main geomorphic features, the drainage pattern of the Rtb, to calculate the morphometric parameters and to delimit the landslides’ bodies. Detailed analysis about the landslide distribution within a test site 17 km2 wide were carried out to elaborate indicative indexes of the landslides type and to single out the lithotypes that are more involved in slope instability phenomena. The morphometric parameters indicate the rejuvenation state within the Rtb where the stream reaches show the effects of increased energy relief in agreement with the geological settings of this sector of the Apennine-Maghrebian Chain.

Here the authors present results of an isotope study on precipitation collected during a 2-a period from a rain-gauge network consisting of 6 stations located at different elevations in the Hyblean Mountains (HM) region, in south-eastern Sicily. The slope of the local meteoric water line ({delta}D = 6.50 {delta} {sup 18}O + 9.87) obtained for the region suggests that precipitation is affected by evaporation during rainfall events. The main variations in rainwater isotope composition are due to seasonal effects and elevation. An average {sup 2}H excess value of +21.2 per mille was found for precipitation events less affected by evaporation (i.e. when the rainfall was >65 mm/month). The spatial distribution of O isotope composition of precipitation shows a negative gradient from east and south to the inner areas. The depositional rate of Cl, used as a tracer of the origin of air masses, is highest at the coastal rain-gauges (SR and MRG stations) and lowest on the northern flank of the HM region (SC station). Based on these findings, a model is proposed for the origin of precipitation in the HM region, which assumes that a Mediterranean-derived component is the main source of moisture in the studied area. D/H and {sup 18}O/{sup 16}O ratios of inferred meteoric recharge waters were also compared with the isotope composition of waters collected from the main local springs and wells. The best linear fit of the {delta} {sup 18}O vs {delta}D relationship for Hyblean groundwater is {delta}D = 4.85 {delta} {sup 18}O-2.01. The enrichment of heavy isotopes in Hyblean groundwater is probably due to evaporation occurring after precipitation events or to a recharging contribution from surface waters (lakes or rivers) enriched in heavy isotopes.

The enrichment of heavy isotopes in Hyblean groundwater is probably due to evaporation occurring after precipitation events or to a recharging contribution from surface waters (lakes or rivers) enriched in heavy isotopes

Analysis of the seismicity of Southeastern Sicily: a proposed tectonic interpretation

Full Text Available Southeastern Sicily is one of the Italian regions with high seismic risk and is characterised by the occurrence in the past of large destructive events (MS = 6.4-7.3 over a territory which is densely urbanised today. The main earthquakes were analysed and some minor damaging shocks reviewed to investigate the main seismogenic features of the region. The comparison between the pattern of seismicity and evidence of Quaternary tectonics allowed us to propose a first tentative, tectonic interpretation of the earthquakes. On the whole, the seismicity of SE Sicily seems distributed along regional fault systems which have had a role in the recent geodynamic evolution of the area. The Malta escarpment, the only structure whose late Quaternary-recent activity is currently known, appears the most probable source for earthquakes with about 7 magnitude. Although no evidence of tectonics subsequent to the middle Pleistocene is available for them, the Scicli line and the NE-SW fault system delimiting the northern sector of the Hyblean plateau seem seismically active with events with maximum magnitude of 5.2 and 6.4, respectively.

Microscopic blebs of sulfur-bearing organic matter (OM) commonly occur between the secondary calcite grains and fibrous phyllosilicates in extensively serpentinized and carbonated mantle-derived ultramafic xenoliths from Hyblean nephelinite diatremes, Sicily, Italy. Rarely, coarse bituminous patches give the rock a blackish color. Micro Fourier transform infrared spectra (μ-FTIR) point to asphaltene-like structures in the OM, due to partially condensed aromatic rings with aliphatic tails consisting of a few C atoms. X-ray photoelectron spectroscopy (XPS) analysis indicates the occurrence of minor S═O (either sulphonyl or sulphoxide) functional groups in the OM. Solubility tests in toluene, thermo-gravimetric (TGA) and differential thermal (DTA) analyses confirm the presence of asphaltene structures. It is proposed that asphaltenes derive from the in situ aromatization (with decrease in H/C ratio) of previous light aliphatic hydrocarbons. Field evidence excludes that hydrocarbon from an external source percolated through the xenolith bearing tuff-breccia. The discriminating presence of hydrocarbon in a particular type of xenolith only and the lack of hydrocarbon in the host breccia matrix, are also inconsistent with an interaction between the ascending eruptive system and a supposed deep-seated oil reservoir. Assuming that the Hyblean unexposed basement consists of mantle ultramafics and mafic intrusive rocks having hosted an early abyssal-type hydrothermal system, one can put forward the hypothesis that the hydrocarbon production was related to hydrothermal activity in a serpentinite system. Although a bacteriogenesis or thermogenesis cannot be ruled out, the coexisting serpentine, Ni-Fe ores and hydrocarbon strongly suggest a Fischer-Tropsch-type (FTT) synthesis. Subsequent variations in the chemical and physical conditions of the system, for example an increase in the water/rock ratio, gave rise to partial oxidation and late carbonation of the serpentinite

Full Text Available A syntaxonomical revision of the class Querco-Fagetea sylvaticae in Sicily, based on literature data and unpublished relevés, is presented. This class groups the mesophilous woods characterized by the dominance of deciduous trees (e.g. Fagus sylvatica, Quercus sp. pl., Acer sp. pl., and more rarely by conifers (Taxus baccata, Pinus nigra subsp. calabrica, as well as by other broadleaved trees, such as Betula aetnensis, Populus tremula, Castanea sativa. In Sicily, these woody communities are widespread in the northern and north-eastern districts of the island, chiefly on the highest peaks (Madonie, Nebrodi, Peloritani, and Etna. This class is represented in Sicily by two, both floristically and ecologically well differentiated orders: Fagetalia sylvaticae, with the sole alliance Geranio versicoloris-Fagion sylvaticae, and Quercetalia pubescenti-petraeae, with the endemic alliance Pino calabricae-Quercion congestae. On the whole, 22 associations have been recognized within the class Querco-Fagetea and for each of them nomenclature, floristic assessment, ecology, syndinamic relationships, and chorology are examined.

Full Text Available Dietary polyphenols gained the interest of the scientific community due to their wide content in a variety of plant-derived foods and beverages commonly consumed, such as fruits, vegetables, coffee, tea, and cocoa. We aimed to investigate whether there was an association between dietary phenolic acid consumption and prostate cancer (PCa in South Italy. We conducted a population-based case-control study from January 2015 to December 2016 in a single institution of the municipality of Catania, southern Italy (Registration number: 41/2015. Patients with elevated PSA and/or suspicious PCa underwent transperineal prostate biopsy. A total of 118 histopathological-verified PCa cases were collected and a total of 222 controls were selected from a sample of 2044 individuals. Dietary data were collected by using two food frequency questionnaires and data on the phenolic acids content in foods was obtained from the Phenol-Explorer database (www.phenol-explorer.eu. Association between dietary intake of phenolic acids and PCa was calculated through logistic regression analysis. We found lower levels of caffeic acid (2.28 mg/day vs. 2.76 mg/day; p < 0.05 and ferulic acid (2.80 mg/day vs. 4.04 mg/day; p < 0.01 in PCa when compared to controls. The multivariate logistic regression showed that both caffeic acid (OR = 0.32; p < 0.05 and ferulic acid (OR = 0.30; p < 0.05 were associated with reduced risk of PCa. Higher intake of hydroxybenzoic acids and caffeic acids were associated with lower risk of advanced PCa. High intake of caffeic acid and ferulic acid may be associated with reduced risk of PCa.

permanent displacement potentially induced by an seismic scenario. Such methodologies found on the consideration that the conditions of seismic stability and the post-seismic functionality of engineering structures are tightly related to the entity of the permanent deformations that an earthquake can induce. Regarding the existing simplified procedures among slope stability models, Newmark's model is often used to derive indications about slope instabilities due to earthquakes. In this way, we have evaluated the seismically-induced landslides hazard in Sicily (Central Mediterranean) using the Newmark-like model. In order to determine the map distribution of the seismic ground-acceleration from an earthquake scenario, the attenuation-law of Sabetta & Pugliese has been used, analyzing some seismic recordings occurred in Italy. Also, by evaluating permanent displacements, the correlation of Ambraseys & Menu has been assumed. The seismic shaking slope vulnerability map of Sicily has been carried out using GIS application, also considering max seismic ground-acceleration peak distribution (in terms of exceedance probability for fixed time), slope acclivity, cohesion/angle of internal friction of outcropping rocks, allowing the zoning of the unstable slopes under seismic forces.

Full Text Available Digital documentation and 3D modelling of archaeological sites are important for understanding, definition and recognition of the values of the sites and of the archaeological finds. The most part of archaeological sites are outdoor location, but a cover to preserve the ruins protects often parts of the sites. The possibility to acquire data with different techniques and merge them by using a single reference system allows creating multi-parties models in which 3D representations of the individual objects can be inserted. The paper presents the results of a recent study carried out by Geomatics Laboratory of University of Palermo for the digital documentation and 3D modelling of Eraclea Minoa archaeological site. This site is located near Agrigento, in the south of Sicily (Italy and is one of the most famous ancient Greek colonies of Sicily. The paper presents the results of the integration of different data source to survey the Eraclea Minoa archaeological site. The application of two highly versatile recording systems, the TLS (Terrestrial Laser Scanning and the RPAS (Remotely Piloted Aircraft System, allowed the Eraclea Minoa site to be documented in high resolution and with high accuracy. The integration of the two techniques has demonstrated the possibility to obtain high quality and accurate 3D models in archaeological survey.

Within the framework of the Tunisian - EC SALTO/AVICENNE project, four hydrological sections were performed between Tunisia, Sardinia and Sicily with a 10-20 km sampling interval in April-June 1995. To our knowledge, it is the first time that sections were repeated there at such a high frequency. These data significantly increase the number of observations available on the Tunisian side of the Channels of Sardinia and Sicily, and allow reliable specification of the hydrological characteristics of the area. For the first time, and as confirmed by infrared satellite images, these data sets show (i) the large mesoscale variability of the surface flow entering the study area, as expected from the characteristics of the Algerian Current upstream, (ii) the rapid changes it undergoes around northeastern Tunisia, as it shifts roughly from southward to eastward within less than a few weeks. These data also show a large heterogeneity at intermediate levels, clearly associated with waters of very different origins that follow converging routes and mix in both the study area and the southern Tyrrhenian Sea. They finally document the fundamental importance of bathymetric features of relatively small scale such as the Skerki passage.

Canker and decline caused by Neofusiccocum parvum on Acacia melanoxylon in Italy

Full Text Available In the spring of 2012, in reforested areas of Peloritani Mountains (Sicily, Italy a severe dieback of Acacia melanoxylon R. Brown was observed. The main symptoms on both young and adults plants consisted of elongated cankers on the trunks and epicormic shoots, wilt of the canopy and dieback interested mostly aged trees. The woody tissues showed browning beyond the cankers. Sapwood and heartwood appeared decayed with a brown to gray-greenish discoloration. One fungal species was consistently isolated from infected woody tissues, which was morphologically attributed to Neofusiccocum sp. The sequencing of the ITS regions of a representative isolate allowed to identify (99% similarity the species Neofusiccocum parvum (Pennycook & Samuels Crous, Slippers and Phillips, teleomorph Botryosphaeria parva Pennycook & Samuels. The pathogenicity tests have reproduced symptoms similar to those observed in the field. N. parvum is the aetiologic agent of mortality of australian blackwood observed in Sicily and to our knowledge this is the first report of this fungus on Acacia melanoxylon. It is a generalist pathogen, cosmopolitan, present in many temperate areas, Mediterranean and subtropical. The older Peloritani Mountains populations of australian blackwood seem particularly susceptible to the pathogen, the latter favored by the lack of silvicultural interventions that generate interspecific and intraspecific competition, as well as the increase and spread of the fungus. To minimize the consequential damage is necessary to adopt sanitation measures that would lower the fungal inoculum and program substitutions of this exotic species with others that have multiple functions suited to environments (e.g., Chestnut or encouraging the establishment and development of native species, such as the holm oak and shrub.

Women’s Activism and Innovation in Education: the Role of the Unione Femminile Nazionale in Sicily for the Transformation of Italian Pedagogy at the Beginning of the Twentieth Century

Directory of Open Access Journals (Sweden)

Letterio Todaro

2017-01-01

Full Text Available The beginning of the twentieth century represented a special occasion in the development of women’s movements as a vehicle for a new culture of education. The growing role of women’s associations in modern society found fertile ground in the increasing demand for childcare. In Italy such a process reflected a meaningful phenomenon of social transformation, which was linked to the ascent of the lower classes and to the progression of democratic values. In a region like Sicily, the appearance of local branches of the Unione Femminile Nazionale in some principal cities of the isle, such as Catania, from 1909 onwards represented a crucial opportunity not only for the social and cultural elevation of working-class children, but also for the introduction of new models of schooling and the experimentation of new methods in education, within the wider framework of a general renewal in the science of education of the time. The most representative witness and «learner» of these innovative approaches to education was Giuseppe Lombardo Radice, who was to «transfer» many aspects of his experience into the reform of the entire primary school system in Italy (1923 in line with the design of «active schooling». A survey of the experience of the Sicilian sections of the Unione provides not only a significant example of civilization processes promoted by women’s activism, but also a key to better understanding the wealth of resources involved in the construction of a modern pedagogy in Italy before the coming of Fascism.

This study investigated the nurseries of seven commercially important demersal species of the northern sector of the Strait of Sicily (central Mediterranean): red mullet, European hake, horned octopus, deep-water rose shrimp, greater forkbeard, Norway lobster and giant red shrimp. An eleven-year series of data collected through experimental trawling in the Strait of Sicily during spring and autumn was analyzed. The spatio-temporal persistence of the high-density aggregations (hot spots) of juvenile individuals in their first year of life was investigated to identify habitats that serve as nurseries. The density of recruits within the persistent nurseries was used as a proxy of the unit area contribution of individuals which recruit to the adult population. The spatial distribution patterns of the recruits of most the species were well defined and very stable in the long term. Persistent and potentially highly productive nurseries of European hake, deep-water rose shrimp and greater forkbeard were identified off the southern coast of Sicily. Persistent areas of recruits concentration were also observed for the other species investigated, but their specific potential contribution of individuals to the adult population was not substantial compared to adjacent grounds. The close or overlapped localization of sites which regularly host vulnerable life stages of different exploited species, revealed an area of great ecological significance which probably plays a major role in the dynamics of the fishery resources in the Strait of Sicily. Appropriate spatial protection measures of this area, including marine protected area designation, could complement conventional management approach for ensuring the long-term sustainability of these fisheries and stocks conservation.

Living on the edge: assessing the extinction risk of critically endangered Bonelli's eagle in Italy.

Directory of Open Access Journals (Sweden)

Pascual López-López

Full Text Available BACKGROUND: The population of Bonelli's eagle (Aquila fasciata has declined drastically throughout its European range due to habitat degradation and unnatural elevated mortality. There are less than 1500 breeding pairs accounted for in Europe, and the species is currently catalogued as Critically Endangered in Italy, where the 22 territories of Sicily, represent nearly 95% of the entire Italian population. However, despite national and European conservation concerns, the species currently lacks a specific conservation plan, and no previous attempts to estimate the risk of extinction have been made. METHODOLOGY/PRINCIPAL FINDINGS: We incorporated the most updated demographic information available to assess the extinction risk of endangered Bonelli's eagle in Italy through a Population Viability Analysis. Using perturbation analyses (sensitivity and elasticity, and a combination of demographic data obtained from an assortment of independent methods, we evaluated which demographic parameters have more influence on the population's fate. We also simulated different scenarios to explore the effects of possible management actions. Our results showed that under the current conditions, Bonelli's eagle is expected to become extinct in Italy in less than 50 years. Stand-alone juvenile mortality was the most critical demographic parameter with the strongest influence on population persistence with respect to other demographic parameters. Measures aimed at either decreasing juvenile mortality, adult mortality or decreasing both juvenile and adult mortality resulted in equivalent net positive effects on population persistence (population growth rate λ>1. In contrast, changes aimed at increasing breeding success had limited positive effects on demographic trends. CONCLUSIONS/SIGNIFICANCE: Our PVA provides essential information to direct the decision-making process and exposes gaps in our previous knowledge. To ensure the long-term persistence of the species

This paper examines the interrelationship between the natural and human history of Sicily over the last 2000 years. It presents a close comparison of the data from the key multi-proxy site of Lago di Pergusa - located inland in the eastern part of Sicily - with the existing archaeological and textual evidence on the socio-economic processes. The article also includes a review of the available natural proxy archives from the Central Mediterranean. On the basis of the isotope and pollen data from the Lago di Pergusa core PRG2, we identified two humid periods (ca. 450-750 AD and ca. 1400-1800 AD) as well as a dry one (ca. 1100-1350 AD); our evidence corresponds closely with other environmental palaeoclimate proxies from the Mediterranean region. In our synthesis of the environmental, historical and archaeological evidence from southern Italy, we argue that during both periods of increased humidity - that is during the late antique-Byzantine times and during the late medieval and early modern periods - intense agricultural use of the Sicilian landscape developed on an unprecedented scale. This in turn contributed to the impressive demographic and economic expansion visible during these periods. A sudden period of aridity followed the first of these eras of humidity-related agricultural growth. This climatic shift, dated to around 750 AD, corresponds to a decrease in synanthropic taxa and a recovery of arboreal vegetation. We argue that in this case a climatic change contributed to socio-economic decline. Moreover, as this change occurred prior to the Arab invasion of Sicily in AD 827, the environmental processes may help to explain the collapse of Byzantine society on Sicily which, in turn made the Muslim conquest possible. After this event, there occurred a longer period of agricultural decline, lasting until around 1000 AD, after which we see the first signs of a slow recovery. Ongoing research in nearby archaeological sites will help defining if it was a local

tilting, which induces synchronously mass elevation and subsidence. Not considering sea-level fluctuations and the climatic-lithologic parameters, the 2D distribution of uplift rate influences the landmass evolution in time. The tendency of rock masses to equilibrium resulting from concurrent tectonic building and denudation forces defines the geomorphic cycle. This evolution is checked by different stages, each characterised by a well-recognisable morphometric patterns. The dominance of uplift or erosion and concurrent block tilting induce characteristic a landform evolution tendency, which may be evaluated with the morphometric analysis. A lot of morphometric functions describe the equilibrium stage of landmasses, providing useful tools for deciphering how tectonics acts in typology (e.g. inducing uplift uniformly or with crustal block tilting) and resulting effects on landforms (magnitude of uplift rate vs tilting rate). We aim to contribute in the description of landforms evolution in Sicily (Central Mediterranean) under different morphoevolutive settings, where may prevails uplift, tilting or erosion, each characterised by different morphometric trends. The present-day elevation of Pliocene to upper Pleistocene deposits suggests that Northen Sicily underwent neotectonic uplift. The recent non-uniform uplift of Northern Sicily coastal sector is suggested by the different elevation of the Pliocene-Upper Pleistocene marine deposits. The maximum uplift rate characterise the NE Sicily and the minimum the NW Sicily. The overall westwards decreasing trend of uplift is in places broken in the sectors where are located a lot of morphostructures. Localised uplift rates higher than the adjacent coastal plains are suggested by the present-day elevation of the beachshore deposits of Tyrrhenian age. Northern Sicily may be divided into a lot of crustal blocks, underwent to different tilting and uplift rates. Accentuate tilting and uplift results from transtensional active faulting

Integrated techniques to evaluate the features of sedimentary rocks of archaeological areas of Sicily

Full Text Available Sicily includes a great variety of lithologies, giving a high complexity to the geologic landscape. Their prevalent lithology is sedimentary. It is well known that rocks of sedimentary origin, compared with metamorphic and volcanic deposits, can be relatively soft and hence fairly easy to model. Nevertheless, this workability advantage is a drawback for Cultural Heritage applications. In fact, these materials show a high porosity, with pore-size distributions that lead to deterioration through absorption of water. In this paper, several sedimentary rocks used in historical Cultural Heritage items of Sicily, from "Magna Graecia" to nowadays, are classified for mineralogical features, chemical composition, and for porosity. Particularly, some samples collected in quarries relevant to the archaeological sites of 41 Agrigento, Segesta and Selinunte will be considered and characterized using integrated techniques (XRD, XRF, NMR and CT. Data on samples obtained in laboratory will be compared with the relevant values measured in situ on monuments of historical-cultural interest of the quoted archaeological places.

Crustal and deep seismicity in Italy (30 years after

1997-06-01

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

Full Text Available The article deals with the description and analysis of functioning of the Italian national system of economic diplomacy.The author provides an insight into the historical and economic background and conditions of its development from the earliest stages to present time focusing on the latest events (from 2010 onwards.He casts light upon the procedures and mechanisms of interaction between the key national economic-diplomatic agents i.e. ministry of foreign affairs, ministry of economic development, export-promotion agency ITA, investment-attraction agency Invitalia, other authorized bodies (in particular, the Coordination Council on the Internationalization of the Italian Economy - CRII, public and private institutes. The article outlines the main principles of the new system of foreign economic policy "Sistema Paese" which is being implemented since 2011. This concept is based upon efficient cooperation ("team play" between the chief institutes of economic diplomacy with a system approach to elaboration and realizing measures aimed at the internationalization of the Italian business. Innovative elements of "Sistema Paese" do not just imply another reorganization of the MFA, but a completely new approach to issues concerning the position of Italy on the world arena. The author looks into concrete mechanisms of economic diplomacy which basically include measures of national export promotion and assistance to Italian companies in the course of new markets penetration, as well as measures on attraction of foreign direct investment inter alia from developing countries. He mentions that subnational regions of Italy, especially Friuli-Venezia Giulia, Veneto and Sicily, tend to be more and more involved into processes of FDI attraction. Another important trend and particular feature of Italy's modern economic diplomacy is the practice of decentralization of financial management within the MFA system through providing the heads of diplomatic

The house mouse Mus musculus domesticus is characterized by more than 100 metacentric populations, due to the occurrence of Robertsonian (Rb) fusions, together with the standard all-telocentric karyotype (2n = 40). We examined G-banded karyotypes of 18 mice from 10 localities in Sicily and describe 3 new metacentric populations: 'Ragusa Ibla' (IRAG), 2n = 33-36, Rb(2.4), Rb(5.6), Rb(9.16), Rb(13.17); 'Piana degli Albanesi' (IPIA), 2n = 23, Rb(1.18), Rb(2.15), Rb(3.5), Rb(4.12), Rb(6.11), Rb(7.8), Rb(9.16), Rb(10.14), Rb(13.17); 'Trapani' (ITRA), 2n = 22, Rb(1.18), Rb(2.15), Rb(3.7), Rb(4.12), Rb(5.9), Rb(6.11), Rb(8.16), Rb(10.14), Rb(13.17). Three mice belonged to the previously reported 'Castelbuono' race (ICAS), 2n = 24, which is very similar to the nearby 'Palermo' (IPAL) race, 2n = 26. Three Rb fusions not yet observed in wild mouse populations were identified: Rb(3.5), Rb(3.7) and Rb(5.9). Rb fusions shared among 4 races (IPIA, IRAG, ICAS, and IPAL) allowed us to describe their potential phylogenetic relationships. We obtained 2 alternative phylogenetic trees. The differences between them are mainly due to various modes of formation of IPIA and ITRA. In the first hypothesis, the specific Rb fusions occurred independently. In the second, those of IRAG originated from those of IPIA via whole-arm reciprocal translocations. © 2015 S. Karger AG, Basel.

In this paper, terrain susceptibility to earth-flow occurrence was evaluated by using geographic information systems (GIS) and two statistical methods: Logistic regression (LR) and multivariate adaptive regression splines (MARS). LR has been already demonstrated to provide reliable predictions of earth-flow occurrence, whereas MARS, as far as we know, has never been used to generate earth-flow susceptibility models. The experiment was carried out in a basin of western Sicily (Italy), which extends for 51 km2 and is severely affected by earth-flows. In total, we mapped 1376 earth-flows, covering an area of 4.59 km2. To explore the effect of pre-failure topography on earth-flow spatial distribution, we performed a reconstruction of topography before the landslide occurrence. This was achieved by preparing a digital terrain model (DTM) where altitude of areas hosting landslides was interpolated from the adjacent undisturbed land surface by using the algorithm topo-to-raster. This DTM was exploited to extract 15 morphological and hydrological variables that, in addition to outcropping lithology, were employed as explanatory variables of earth-flow spatial distribution. The predictive skill of the earth-flow susceptibility models and the robustness of the procedure were tested by preparing five datasets, each including a different subset of landslides and stable areas. The accuracy of the predictive models was evaluated by drawing receiver operating characteristic (ROC) curves and by calculating the area under the ROC curve (AUC). The results demonstrate that the overall accuracy of LR and MARS earth-flow susceptibility models is from excellent to outstanding. However, AUC values of the validation datasets attest to a higher predictive power of MARS-models (AUC between 0.881 and 0.912) with respect to LR-models (AUC between 0.823 and 0.870). The adopted procedure proved to be resistant to overfitting and stable when changes of the learning and validation samples are

Kawasaki disease in Sicily: clinical description and markers of disease severity

Southern Italy has a long history of human occupation and passage of different cultures since the Early Holocene. Repeated, ancient introductions of pigs in several geographic areas in Europe make it difficult to understand pig translocation and domestication in Italy. The archeozoological record may provide fundamental information on this, hence shedding light on peopling and on trading among different ancient cultures in the Mediterranean. Yet, because of the scanty nature of the fossil record, ancient remains from human-associated animals are somewhat rare. Fortunately, ancient DNA analysis as applied to domestic species proved to be a powerful tool in revealing human migrations. Herein, we analyzed 80-bp fragment of mitochondrial DNA control region from 27 Sus scrofa ancient samples retrieved from Southern Italian and Sardinian archeological sites, spanning in age from the Mesolithic to the Roman period. Our results surprisingly indicate the presence of the Near Eastern haplotype Y1 on both Italy's major islands (Sardinia and Sicily) during the Bronze Age, suggesting the seaborne transportation of domestic pigs by humans at least during 1600-1300 BC. The presence of the Italian E2 clade in domestic contexts shows that the indigenous wild boar was effectively domesticated or incorporated into domestic stocks in Southern Italy during the Bronze Age, although the E2 haplotype has never been found in modern domestic breeds. Pigs belonging to the endemic E2 clade were thus traded between the Peninsula and Sardinia by the end of the second millennium BC and this genetic signature is still detected in Sardinian feral pigs.

Italy of censuses.

Rey, G M

To supplement census data on Italy's economy, Istat conducted a sample survey of 2% of households. This paper reports survey findings in 3 areas: age structure of the population, employment and unemployment patterns by region, and structure of the productive system. Those over age 65 years have increased from 11% of the population in 1971 to 13% in 1981 and are forecast to constitute 14.5% in 1991. Women accounted for 51.3% of the total population in 1981 but 58.5% of those over age 65. 12% of households have a member over age 75. The 0-14 year age group has declined from 24.4% of the population in 1971 to 21.5% in 1981 and is projected to comprise 17.4% in 1991. The labor force activity rate was 39.8% in 1981. Unemployment was set at 14.7% in the census sample compared with 9.1% in Istat's quarterly survey of the labor force. 60% of the difference between these 2 figures was accounted for by Campania, Sicily, Puglia, Calabria, and Latium. These 5 regions, which account for only 30% of total employment, are the areas with the most acute employment problems and highest proportions of casual employment in agriculture and traditional services. Agriculture accounted for 22% of total unemployment, construction for 18.5%, and traditional industry for 14%--percentages that are higher than the share of total employment represented by these sectors. In the South, 20.4% of employment is in agriculture, 18.1% in industry, 12.6% in construction, and 48.9% in services. The average worker in the South supports 3.3 persons compared with 2.5 persons in the North. Survey results indicate a substantial shift in the sectoral composition of employment as well as a change in the size of productive units. There has been an increase in the highly specialized components of the economy, including services to firms. The average size of factories has declined, with a proliferation of small and medium sized units. These findings suggest a need to broaden and deepen Italy's industrial base

Tracking the invasion of the red swamp crayfish Procambarus clarkii (Girard, 1852 (Decapoda Cambaridae in Sicily: a “citizen science” approach

Directory of Open Access Journals (Sweden)

Francesco Paolo Faraone

2017-11-01

Full Text Available The first record of the red swamp crayfish in Sicily dates back to 2003 and, since then, the species seemed to be confined to a few localities in western Sicily. A small “citizen science” project carried out from November 2016 onwards led to the creation of the “Sicilian Procambarus working group” (SPwg, which aims at monitoring the distribution and impact of the species in Sicily. To date, the SPwg found the red swamp crayfish in five new sites on the island, thus doubling the number of local sites of occurrence. The new Procambarus clarkii sites lie in different river basins, some of them located several hundred kilometres from the invaded areas known to date, suggesting the existence of multiple independent releases of the species in the wild. The need of better informing the local population on the risks exerted by invasive species on biological diversity, and of carefully monitoring the impact of P. clarkii on the Sicilian inland water biota is briefly stressed.

Anthropogenic Influences in Land Use/Land Cover Changes in Mediterranean Forest Landscapes in Sicily

Donato S. La Mela Veca

2016-01-01

Full Text Available This paper analyzes and quantifies the land use/land cover changes of the main forest and semi-natural landscape types in Sicily between 1955 and 2012. We analyzed seven representative forest and shrubland landscapes in Sicily. These study areas were chosen for their importance in the Sicilian forest panorama. We carried out a diachronic survey on historical and current aerial photos; all the aerial images used to survey the land use/land cover changes were digitalized and georeferenced in the UTM WGS84 system. In order to classify land use, the Regional Forest Inventory 2010 legend was adopted for the more recent images, and the CORINE Land Cover III level used for the older, lower resolution images. This study quantifies forest landscape dynamics; our results show for almost all study areas an increase of forest cover and expansion, whereas a regressive dynamic is found in rural areas due to intensive agricultural and pasturage uses. Understanding the dynamics of forest landscapes could enhance the role of forestry policy as a tool for landscape management and regional planning.

New strategic solid waste management in Sicily

Messineo, A.; Panno, D.; Ticali, D.

2005-01-01

The solid waste management is, today, a very critical issue. In spite of all the attempts in order to recovery and to recycle waste, the dump still remains the more followed solution, while only a small part of solid waste is going to be burnt down. But the rubbish dump isn't, actually, an environmentally sustainable solution. In the last years the waste incineration systems with energy recovery are spreading more over the territory, and if on one hand they allow to recover energy, on the other they also generate waste. So the emergency remains and it has to be faced. Today, the waste incineration system with energy recovery seems to be the best solution for this problem. the following article examinates the main strategic aspects of the solid waste management in Sicily after the General Plan of Waste Management application [it

Craft dynasties as a historiographical dilemma for the architecture of south-oriental Sicily in the 16th century

Marco Rosario Nobile

2016-12-01

Full Text Available The essay examines the case of the documented beginnings of a dynasty of master builders (in south-east Sicily in the mid 16th century: the Odierna family. The brevity and incompleteness of the sources lead to an initial, superficial interpretation; a simple artisan dimension with little real information. However, it requires an additional - deeper interpretation to grasp the true picture - of the first modern age of the Island. After the 1542 earthquake, a multi-disciplinary study of the surviving monuments, of the patrons and of the relations with the other artists reveal a moment of particular activity in the area, enriched by the still mysterious but talented “external” presences.  Keywords: Sicily, master builders, 16tn century, Odierna family

Full Text Available One of the parasite diseases associated with the consumption of raw fish that occurs with some frequency is the anisakiasis, a human disease caused by the accidental ingestion of larval nematodes of the genus Anisakis, family Anisakidae. At the National Reference Centre for Anisakiasis (C.Re.N.A. from October 2012 to February 2013, a number of 231 bony fish (Trichiuridae, Engraulidae, Scombridae and Clupeidae were received from different fishing sites in Sicily. Anisakis pegreffii is the main species detected in fish, as identified by molecular analysis based on polymerase chain reaction-restriction fragment length polymorphism, while Anisakis simplex sensu stricto was found only in Scomber scombrus caught in the Mediterranean Sea (Fishing Areas 37, in the Spanish coast (Fishing Areas 37 and in the Atlantic Ocean (Fishing Areas 34. Larvae of the genus Pseudoterranova were found only in fish caught in the Norwegian Sea.

Seasonal variability of water transport through the Straits of Gibraltar, Sicily and Corsica, derived from a high-resolution model of the Mediterranean circulation

Science.gov (United States)

Béranger, K.; Mortier, L.; Crépon, M.

2005-08-01

The variability of the water transport through three major straits of the Mediterranean Sea (Gibraltar, Sicily and Corsica) was investigated using a high-resolution model. This model of the Mediterranean circulation was developed in the context of the Mercator project. The region of interest is the western Mediterranean between the Strait of Gibraltar and the Strait of Sicily. The major water masses and the winter convection in the Gulf of Lions were simulated. The model reproduced the meso-scale and large-scale patterns of the circulation in very good agreement with recent observations. The western and the eastern gyres of the Alboran Sea were observed but high interannual variability was noticed. The Algerian Current splits into several branches at the longitude of the Strait of Sicily level, forming the Tyrrhenian branch, and, the Atlantic Ionian Stream and the Atlantic Tunisian Current in the eastern Mediterranean. The North Current retroflexed north of the Balearic Islands and a dome structure was observed in the Gulf of Lions. The cyclonic barotropic Algerian gyre, which was recently observed during the MATER and ELISA experiment, was evidenced in the simulation. From time-series of 10-day mean transport, the three straits presented a high variability at short time-scales. The transport was generally maximum, in April for the Strait of Gibraltar, in November for the Strait of Sicily, and in January for the Strait of Corsica. The amplitudes of the transport through the Straits of Gibraltar (0.11 Sv) and Sicily (0.30 Sv) presented a weaker seasonal variability than that of the Strait of Corsica (0.70 Sv). The study of the relation between transport and wind forcing showed that the transport through the Strait of Gibraltar is dependent on local zonal wind over short time-scales (70%), which was not the case for the other straits (less than 30%). The maximum (minimum) of the transport occurred for an eastward (westward) wind stress in the strait. An interannual

Soil radon has been monitored at a fixed location on the northeastern flank of Mt. Etna, a high-risk volcano in Sicily. The aim of this study was to evaluate the effects of the recent volcanic activity on soil radon concentration. Continuous radon measurements have been performed since July 2001. While comparison between the trend in in-soil radon concentration and the acquired meteorological series (temperature, humidity and pressure) appear to confirm a general seasonal correlation, nevertheless particular anomalies suggest a possible dependence of the radon concentration on volcanic dynamics

Full Text Available The present work was carried out to investigate the microbiological profile of Sicilian ewes’ ricotta cheeses during fifteen years of investigations (2002-2016. The samples were collected between those conferred to the Istituto Zooprofilattico Sperimentale della Sicilia (IZSSi Adelmo Mirri, Palermo (Italy, by the competent authority during official control, by food business operator in HACCP systems and in research projects. Enterobacteriaceae, Escherichia coli and coagulase-positive staphylococci (CPS were found only in some samples. Bacillus cereus was detected in c.a. 16% of samples but the level of contaminations did not reach the threshold that leads to significant toxin production. Pathogenic bacteria such as Listeria monocytogenes, Salmonella spp. and Brucella spp. were never detected. Furthermore, a total of 47 of lactic acid bacteria (LAB strains were identified at species level by sequencing the 16S rRNA gene, resulting in the identification of 10 species belonging to four genera Enterococcus, Lactobacillus, Lactococcus and Leuconostoc, commonly employed as starter and non starter cultures in different traditional cheese. Results of this study highlighted an improvement of the hygienic conditions of the Sicilian ewes’ ricotta cheeses during the last ten years of investigation. This observation was confirmed from reduction of undesired microorganisms such as Enterobacteriaceae, E.coli and CPS, used to define the process hygiene criteria. However, in order to improve the final quality of this product are needed further strategy such as the dairy makers training, with the aim to apply a good hygienic practices during the production.

Full Text Available The seismicity and the earthquake risk in Western Sicily are here
evaluated on the basis of the experimental data referring to the historical
and instrumentally recorded earthquakes in this area (from 1248
up to 1968, which have been thoroughly collected, analyzed, tested and
normalized in order to assure the quasi-stationarity of the series of
events.
The approximated magnitude values — obtained by means of a compared
analysis of the magnitude and epicentral intensity values of the
latest events — have allowed to study the parameters of the frequency-
magnitude relation with both the classical exponential model and
the truncated exponential one previously proposed by the author.
So, the basic parameters, including the maximum possible regional
magnitude, have been estimated by means of different procedures, and
their behaviours have been studied as functions of the threshold magnitude.

Assessment of bioenergy potential in Sicily: A GIS-based support methodology

International Nuclear Information System (INIS)

Beccali, Marco; D'Alberti, Vincenzo; Franzitta, Vincenzo; Columba, Pietro

2009-01-01

A Geographical Information System (GIS) supported methodology has been developed in order to assess the technical and economic potential of biomass exploitation for energy production in Sicily. The methodology was based on the use of agricultural, economic, climatic, and infrastructural data in a GIS. Data about land use, transportation facilities, urban cartography, regional territorial planning, terrain digital model, lithology, climatic types, and civil and industrial users have been stored in the GIS to define potential areas for gathering the residues coming from the pruning of olive groves, vineyards, and other agricultural crops, and to assess biomass available for energy cultivation. Further, it was possible to assess the potential of biodiesel production, supposing the cultivation of rapeseed in arable crop areas. For the biomass used for direct combustion purposes, the economic availability has been assessed assuming a price of the biomass and comparing it with other fuels. This assessment has shown the strong competitiveness of firewood in comparison with traditional fossil fuels when the collection system is implemented in an efficient way. Moreover, the economic potential of biodiesel was assessed considering the on-going financial regime for fuel. At the same time, the study has shown a significant competitiveness of the finished biomass (pellets), and good potential for a long-term development of this market. An important result was the determination of biofuel production potential in Sicily. An outcome of the study was to show the opportunities stemming from the harmonisation of Energy Policy with the Waste Management System and Rural Development Plan. (author)

Mediterranean salt giants beyond the evaporite model: The Sicily perspective

Science.gov (United States)

Carmelo Manuella, Fabio; Scribano, Vittorio; Carbone, Serafina; Hovland, Martin; Johnsen, Hans-Konrad; Rueslåtten, Håkon

2017-04-01

Mediterranean salt giants, occurring both in sub-seafloor and in onshore settings (the "Gessoso Solfifera Group"), are traditionally explained by repeated cycles of desiccation and replenishment of the entire basin. However, such hypotheses are strongly biased by mass balance calculations and geodynamic considerations. In addition, any hypothesis without full desiccation, still based on the evaporite model, should consider that seawater brines start to precipitate halite when 2/3 of the seawater has evaporated, and hence the level of the basin cannot be the same as the adjacent ocean. On the other hand, hydrothermal venting of hot saline brines onto the seafloor can precipitate salt in a deep marine basin if a layer of heavy brine exists along the seafloor. This process, likely related to sub-surface boiling or supercritical out-salting (Hovland et al., 2006), is consistent with geological evidence in the Red Sea "Deeps" (Hovland et al., 2015). Although supercritical out-salting and phase separation can sufficiently explain the formation of several marine salt deposits, even in deep marine settings, the Mediterranean salt giant formations can also be explained by the serpentinization model (Scribano et al., 2016). Serpentinization of abyssal peridotites does not involve seawater salts, and large quantities of saline brines accumulate in pores and fractures of the sub-seafloor serpentinites. If these rocks undergo thermal dehydration, for example, due to igneous intrusions, brines and salt slurries can migrate upwards as hydrothermal plumes, eventually venting at the seafloor, giving rise to giant salt deposits over time. These hydrothermal processes can take place in a temporal sequence, as it occurred in the "Caltanissetta Basin" (Sicily). There, salt accumulation associated with serpentinization started during Triassic times (and even earlier), and venting of heavy brines onto the seafloor eventually occurred in the Messinian via the hydrothermal plume mechanism

Full Text Available The adoption of multidisciplinary approaches to foster scientific research in public health and strengthen its impact on society is nowadays unavoidable. Environmental health literacy (EHL may be defined as the ability to search for, understand, evaluate, and use environmental health information to promote the adoption of informed choices, the reduction of health risks, the improvement of quality of life and the protection of the environment. Both public health and environmental health literacy involve access to and dissemination of scientific information (including research findings, individual and collective decision-making and critical thinking. Specific experiences in environmental health literacy have been developed within the Italian National Asbestos Project (Progetto Amianto in Latin American countries where the use of asbestos is still permitted, and in Italy where a specific effort in EHL has been dedicated to the risks caused by the presence of fluoro-edenite fibers in the town of Biancavilla (Sicily. Taking into account the different geographical and socio-economic contexts, both public health and environmental health literacy were addressed to a wide range of stakeholders, within and outside the health domain.

Full Text Available Indoor radon behavior in two sites of SE Sicily was studied as a function of the soil radon concentration. The chosen locations were Ragusa and Modica towns, placed in the Hyblean Plateau (northern margin of the African Plate. Soil samples were analysed by gamma spectrometry to determine the amount of radionuclides. Indoor air and soil gas radon measurements were simultaneously performed in both sites using active detectors. Radon in soil was measured one meter deep. A positive correlation was obtained between indoor radon concentration and the soil gas concentration.

Landslide hazard in the Nebrodi Mountains (Northeastern Sicily)

Cubito, A.; Ferrara, V.; Pappalardo, G.

2005-03-01

The eastern sector of the Nebrodi Mountains (NE Sicily), a part of the Apenninic-Maghrebian orogenic chain, is characterized by an high landslide hazard. The village of S. Domenica Vittoria, which lies in the area, has been particularly affected by various landslide phenomena, with resulting damage to buildings and infrastructure. The rocks outcropping in the area belong to the Cretaceous Monte Soro Flysch; they consist of an alternation of argillaceous and calcareous beds at the base and argillaceous and quartzarenitic beds at the top. The lithotechnical characteristics of the formation and the steepness of the slopes in the area lead to an elevated instability, as testified by the widespread occurrence of sub-vertical arcuate cliffs (landslide scarps) and sub-horizontal areas (landslide terraces), typical of a landslide-controlled morphology. From a kinematics point of view, the observed phenomena can be referred to multiple rotational slides, flows, and complex landslides, often with a retrogressive development and enlargement. Triggering causes lie principally in the intense rainfalls that determine the decay of the geomechanical properties of the terrain and supply discontinuos groundwater circulation that is evident in seasonal springs. Human activity, such as the construction of roads and buildings on steep slopes and dispersal of water from supply systems and sewers has a significant impact as well. Due to the instability of the area, expansion of the village, which is already limited by the morphological conditions, is made difficult by the high hazard level, especially in the areas at higher elevations, where the principal landslide scarps are located, and even more on the rims of the scarps. Considering the high hazard level, S. Domenica Vittoria has been inserted by the National Geological Service among the sites in Sicily to be monitored by means of a GPS network. The survey carried out along the entire slope hosting the village has furnished the base

The main focus of the paper is to present a flood and landslide early warning system, named HEWS (Hydrohazards Early Warning System), specifically developed for the Civil Protection Department of Sicily, based on the combined use of rainfall thresholds, soil moisture modelling and quantitative precipitation forecast (QPF). The warning system is referred to 9 different Alert Zones in which Sicily has been divided into and based on a threshold system of three different increasing critical levels: ordinary, moderate and high. In this system, for early flood warning, a Soil Moisture Accounting (SMA) model provides daily soil moisture conditions, which allow to select a specific set of three rainfall thresholds, one for each critical level considered, to be used for issue the alert bulletin. Wetness indexes, representative of the soil moisture conditions of a catchment, are calculated using a simple, spatially-lumped rainfall-streamflow model, based on the SCS-CN method, and on the unit hydrograph approach, that require daily observed and/or predicted rainfall, and temperature data as input. For the calibration of this model daily continuous time series of rainfall, streamflow and air temperature data are used. An event based lumped rainfall-runoff model has been, instead, used for the derivation of the rainfall thresholds for each catchment in Sicily characterised by an area larger than 50 km2. In particular, a Kinematic Instantaneous Unit Hydrograph based lumped rainfall-runoff model with the SCS-CN routine for net rainfall was developed for this purpose. For rainfall-induced shallow landslide warning, empirical rainfall thresholds provided by Gariano et al. (2015) have been included in the system. They were derived on an empirical basis starting from a catalogue of 265 shallow landslides in Sicily in the period 2002-2012. Finally, Delft-FEWS operational forecasting platform has been applied to link input data, SMA model and rainfall threshold models to produce

On the road of dung: hypothetical dispersal routes of dung beetles in the circum–Sicilian volcanic islands

Energy Technology Data Exchange (ETDEWEB)

Tonelli, M.; Agoglitta, R.; Dawson, H.; Zunino, M.

2016-07-01

We analysed dung beetle communities on ten volcanic islands located around Sicily (Italy) to identify the most probable dispersal routes in the colonization of these islands. Assuming two scenarios, we analysed the dung beetle communities through the coefficient of dispersal direction DD2. Our results suggest that dispersal fluxes do not strictly follow the ‘stepping stone’ dynamic. Lipari and Vulcano are the likely core source areas for the north–of–Sicily area. In the Sicily Channel, Linosa appears to have been the main target area with three equivalent fluxes from Tunisia, Sicily, and Malta, while the fauna of Pantelleria resulted from their interchange and proximity to Tunisian fauna. In light of the congruence of our results with the known history of human movements and colonization, we propose a likely human contribution to the genesis of the dung beetle fauna of the circum–Sicilian volcanic islands.

This study investigates living benthic foraminiferal assemblages as bio-indicators of anthropogenic activities in a coastal area within the Gulf of Palermo (Sicily, Italy), affected by industrial and urban activities, and evaluates the environmental quality through the calibration of a Tolerant Species index (%TS std ). Sediments from 6 stations were sampled along a bathymetric transect from the coast to offshore. Sediment grain size, TOC, major, minor and trace elements and polycyclic aromatic hydrocarbons (PAHs) were compared to benthic foraminiferal assemblages and species at each station. Diversity and density of benthic foraminiferal assemblages were not affected by the presence of pollutants, while tolerant species increased with organic (TOC and PAHs) or chemical (As and Pb) concentrations. Moreover, the calibration of the %TS std formula to >125μm foraminiferal assemblage, gives a detailed description of environmental quality along the transect, representing a good and sensitive tool to evaluate marine coastal environment.

The object of the study was to investigate the opportunity of destination brand-ing through the tool of its gastronomy. In order to render concrete to the topic I chose a popular destination – Sicily and Sicilian gastronomy. It is a fact that the theme of gastronomic direction in tourism and the role of gastronomy in des-tination branding is not developed at all. Besides, personally I have been always attracted by gastronomic experiences in tourism. So it was a challenge for my-self to explor...

Full Text Available Abstract Three dormouse species are recorded in Sicily: Myoxus glis, Muscardinus avellanarius and Eliomys quercinus. Their distribution is mapped according to the 10 x 10 km squares of the UTM grid. Data were collected until May 1993, mostly coming from pellet analysis, and direct records (vocalization listening, museum specimens, field observations, literature, etc.. The Fat dormouse (5.3% of 10 x 10 km squares and the Hazel dormouse (2.1% are mainly localized within deciduous wooded areas like the beech forests and the hazel groves mixed with oaks and chestnuts of Nebrodi and Madonie. The Fat dormouse is also present in south-eastern Sicily (Monti Iblei and on in Eolian island (Salina. The Garden dormouse shows the widest distribution (21.2%, ranging from sea level to the beech forests (1600 m a.s.1.. Dormice are rarely preyed upon by Owls in Sicily, generally forming less than 1.5% of the total prey, with the exception the Fat dormouse (5.3%. Other occasional predators, so far recorded, are the Red Fox (Vulpes vulpes and the Lanner (Falco biarmicus.

Grezio, A.; Gasparini, P.; Marzocchi, W.; Patera, A.; Tinti, S.

2012-01-01

We present a first detailed tsunami risk assessment for the city of Messina where one of the most destructive tsunami inundations of the last centuries occurred in 1908. In the tsunami hazard evaluation, probabilities are calculated through a new general modular Bayesian tool for Probability Tsunami Hazard Assessment. The estimation of losses of persons and buildings takes into account data collected directly or supplied by: (i) the Italian National Institute of Statistics that provides information on the population, on buildings and on many relevant social aspects; (ii) the Italian National Territory Agency that provides updated economic values of the buildings on the basis of their typology (residential, commercial, industrial) and location (streets); and (iii) the Train and Port Authorities. For human beings, a factor of time exposition is introduced and calculated in terms of hours per day in different places (private and public) and in terms of seasons, considering that some factors like the number of tourists can vary by one order of magnitude from January to August. Since the tsunami risk is a function of the run-up levels along the coast, a variable tsunami risk zone is defined as the area along the Messina coast where tsunami inundations may occur.

Full Text Available Abstract Background Artisanal fisheries in the Mediterranean, especially in Italy, have been poorly investigated. There is a long history of fishing in this region, and it remains an important economic activity in many localities. Our research entails both a comprehensive review of the relevant literature and 58 field interviews with practitioners on plants used in fishing activities along the Western Mediterranean Italian coastal regions. The aims were to record traditional knowledge on plants used in fishery in these regions and to define selection criteria for plant species used in artisanal fisheries, considering ecology and intrinsic properties of plants, and to discuss the pattern of diffusion of shared uses in these areas. Methods Information was gathered both from a general review of ethnobotanical literature and from original data. A total of 58 semi-structured interviews were carried out in Liguria, Latium, Campania and Sicily (Italy. Information on plant uses related to fisheries were collected and analyzed through a chi-square residual analysis and the correspondence analysis in relation to habitat, life form and chorology. Results A total of 60 plants were discussed as being utilized in the fisheries of the Western Italian Mediterranean coastal regions, with 141 different uses mentioned. Of these 141 different uses, 32 are shared among different localities. A multivariate statistical analysis was performed on the entire dataset, resulting in details about specific selection criteria for the different usage categories (plants have different uses that can be classified into 11 main categories. In some uses, species are selected for their features (e.g., woody, or habitat (e.g., riverine, etc. The majority of uses were found to be obsolete (42% and interviews show that traditional fishery knowledge is in decline. There are several reasons for this, such as climatic change, costs, reduction of fish stocks, etc. Conclusions Our research

International Uranium Resources Evaluation Project (IUREP) national favourability studies: Italy

International Nuclear Information System (INIS)

1977-10-01

The Italian Republic comprises a 1200 - Km - long peninsula ex- tending from southern Europe into the Mediterranean Sea, and a number of adjacent islands, among which the principals are Sicily and Sardinia. The total area is in excess of 300,000 Sq.Km, the islands account for some 50, 000 Sq.Km. From a physiographic and morphologic point of view, Italy mainly consists of the Alpine region and the Po valley to the North and of the Appennine range and small Coastal plains to the Centre and South. Plains occupied only 20% of the total area, hills and mountains, up to 4,810 m of elevation, contribute almost equally to the remaining 80%. The most promising uranium mineralizations have been found in the Bergamasc Alps, near the small town of Novazza. Pitchblende and minor sphalerite (formation temperature, 80 deg. - 100 deg. C) occur disseminated in volcanics of permian age. The host rocks at the Novazza uranium deposit, consist of an acid ignimbrite with cineritic texture. The rocks have been affected by metasomatism which brought abundant neo-formation minerals such as silica, sericite, carbonates and minor adularia, albite and muscovite. The reasonably assured resources of the Novazza deposit have been estimated to be 1,200 ton of U having a grade of 900 p.p.m. U. Estimated additional resources are 1,000 ton U. Production is scheduled to start in 1980

Full Text Available The purpose of this study was to determine the concentrations of heavy metals (Cd, Pb, Cu, Mn, and Zn in different organs (liver, kidney, muscle, lung, skin, and feathers of buzzards (Buteo buteo, utilized as a “biological indicator” for environmental contamination, from different areas of Sicily and to investigate the relationships between birds sex, age, and weight and metal levels in these samples. All samples of common buzzards were collected at the “Recovery Center of Wild Fauna” of Palermo, through the Zooprophilactic Institute. Potentiometric stripping analysis (PSA was used to determine the content of Cd(II, Cu(II, Mn(II, Pb(II, and Zn(II in bird tissues. For toxic metals, the highest levels of Pb were in liver and those of Cd in lung; Zn levels were higher than Cu and Mn in all tissues analyzed. The concentrations in liver, lung, kidney, and muscle could be considered as an indicative of chronic exposure to metals while the presence of metals in skin could be consequential to storing and elimination processes. The found concentrations of metals in the studied matrices required a highly sensitive method for their determination and a simple sample preparation procedure, and the proposed method was well suited for this purpose.

Origin and diet of the prehistoric hunter-gatherers on the mediterranean island of Favignana (Ègadi Islands, Sicily.

Directory of Open Access Journals (Sweden)

Full Text Available Hunter-gatherers living in Europe during the transition from the late Pleistocene to the Holocene intensified food acquisition by broadening the range of resources exploited to include marine taxa. However, little is known on the nature of this dietary change in the Mediterranean Basin. A key area to investigate this issue is the archipelago of the Ègadi Islands, most of which were connected to Sicily until the early Holocene. The site of Grotta d'Oriente, on the present-day island of Favignana, was occupied by hunter-gatherers when Postglacial environmental changes were taking place (14,000-7,500 cal BP. Here we present the results of AMS radiocarbon dating, palaeogenetic and isotopic analyses undertaken on skeletal remains of the humans buried at Grotta d'Oriente. Analyses of the mitochondrial hypervariable first region of individual Oriente B, which belongs to the HV-1 haplogroup, suggest for the first time on genetic grounds that humans living in Sicily during the early Holocene could have originated from groups that migrated from the Italian Peninsula around the Last Glacial Maximum. Carbon and nitrogen isotope analyses show that the Upper Palaeolithic and Mesolithic hunter-gatherers of Favignana consumed almost exclusively protein from terrestrial game and that there was only a slight increase in marine food consumption from the late Pleistocene to the early Holocene. This dietary change was similar in scale to that at sites on mainland Sicily and in the rest of the Mediterranean, suggesting that the hunter-gatherers of Grotta d'Oriente did not modify their subsistence strategies specifically to adapt to the progressive isolation of Favignana. The limited development of technologies for intensively exploiting marine resources was probably a consequence both of Mediterranean oligotrophy and of the small effective population size of these increasingly isolated human groups, which made innovation less likely and prevented transmission of

2016-08-01

Full Text Available A new tubeworm, Palaeotubus sosiensis gen. et sp. nov., is described from the Permian Pietra di Salomone limestone (Sosio Valley, W Sicily. The new species is characterized by a thick tube ornamented with slightly flared peristomes and numerous longitudinal keels. The internal structure of the tube was obliterated during diagenesis, which prevents the tube unequivocal systematic attribution. Nevertheless, all preserved morphological characters strongly suggest that the new tube belongs to serpulids. When confirmed by further findings, the positive attribution of this new species to serpulids will imply that it represents the ancestor of the Serpulidae, and the earliest evidence of calcareous tubeworm polychaetes from the Palaeozoic.

Lara Riguccio

2016-06-01

Full Text Available Many rural coastal Mediterranean areas suffer from great anthropomorphic pressure. This is due to intensive agriculture, and construction for residential, tourism and industrial uses. The present work investigates the idea of using a landscape project in the Gulf of Gela in South Sicily to recover the dunes and the area behind them. The method used is based on the literature and will evaluate and interpret the dynamics of the landscape, so as to draw up a landscape plan, which can be used to help sustain the assets of the area, in a way, which is compatible with conserving nature. This method was tested in the LIFE11-Leopoldia project, funded by the European Union. The results of the study form part of the landscape project. This project is aimed at connecting the different productive zones in the area, protecting the natural environments and the rural historical patrimony, through combining the modern road networks with the older slower, historic infrastructure. Three different levels of landscape management are proposed: total protection (the dunes, high-level protection (the area behind the dunes where traditional agriculture is practised, buffer areas and ecological connecting areas, medium levels of protection (sustainable agriculture, green connections and ecological corridors. The key aims of the project are as follows: transversality - repairing the agricultural fabric and the relationship between the land and the sea; sustainability - recovering the environmental system and traditional activities; flexibility - agriculture with only minor environmental impact.

Bonanno, Giuseppe

2013-10-01

Nitrogen emissions were assessed by using mosses as bioindicators in a densely inhabited area affected by mud volcanoes. Such volcanoes, locally called Salinelle, are phenomena that occur around Mt. Etna (Sicily, Italy), and are interpreted as the surface outflow of a hydrothermal system located below Mt. Etna, which releases sedimentary fluids (hydrocarbons and Na-Cl brines) along with magmatic gases (mainly CO2 and He). To date, N emissions from such mud volcanoes have been only quantitatively assessed, and no biomonitoring campaigns are reported about the cumulative effects of these emissions. This study analyzed N concentrations in moss, water and soil samples, collected in a 4-year monitoring campaign. The bryophyte Bryum argenteum, a species widely adopted in surveys of atmospheric pollution, was used as a biological indicator. N concentrations in biomonitors showed relatively low values in the study sites. However, the results of this study suggest that N emissions from Salinelle may have an impact on surrounding ecosystems because N values in moss and water showed a significant correlation. N oxides, in particular, contribute to acidification of ecosystems, thus multitemporal biomonitoring is recommended, especially in those areas where N emitting sources are anthropogenic and natural.

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.

Vulnerability to Forced Labour and Trafficking: The case of Romanian women in the agricultural sector in Sicily

Directory of Open Access Journals (Sweden)

Letizia Palumbo

2015-09-01

Full Text Available This paper focuses on labour and sexual exploitation faced by Romanian female workers employed in the agricultural sector in Ragusa, Sicily, Italy. Drawing on fieldwork conducted in 2013 and 2014 with Romanian female farm workers in Ragusa, the paper identifies factors that contribute towards their vulnerability to exploitation. By paying specific attention to the experiences of women who are mothers with dependent children, we look at structural factors that increase their vulnerability and consider how this vulnerability ‘forces’ women into situations whereby they effectively accept and/or submit to abuse. We also highlight how European Union (EU citizenship does not automatically protect migrants from such abuse. This is important because, as we argue, the mistreatment experienced by participants in this study can be regarded as cases of forced labour and trafficking, based on International Labour Organization (ILO indicators[1] and the definition of trafficking provided by the Directive 2011/36/EU. For a long time, these cases have mostly been neglected by incompetent authorities or addressed using only repressive and assistentialist approaches. Thus, this paper also investigates the limits and potentialities of the Italian legal framework on trafficking, and the ways local institutions and organisations confront the rights violations occurring in the agricultural sector. We contend that in order to effectively counter these phenomena, labour rights measures and anti-trafficking interventions have to be combined based on a comprehensive approach aimed not only at assisting victims, but also at tackling the structural factors that create their vulnerability.

Tsunami vulnerability and damage for buildings analyzed by means of two methods (PTVA-3 and SCHEMA) in the area of Augusta and Siracusa, eastern Sicily, Italy

Science.gov (United States)

Pagnoni, Gianluca; Tinti, Stefano

2015-04-01

The coast of the eastern Sicily is exposed to tsunamis that can be generated by local earthquakes (e.g. the 1169, 1693, 1908 events) and by earthquakes located in distant seismic zones (see the 365 AD tsunamigenic quake in Western Hellenic Arc). Tsunamis can also be generated by landslides possibly triggered by earthquakes. The Hyblean-Malta steep escarpment running offshore at a small angle with the coast is an ideal place for submarine mass failure occurrences with tsunamigenic effects. The entire eastern coast of Sicily from Messina in the north to Siracusa in the south is under the threat of tsunamis. In the frame of the FP7 European project ASTARTE (Assessment, Strategy And Risk Reduction for Tsunamis in Europe - FP7-ENV2013 6.4-3, Grant 603839), the segment of coast from Augusta to Siracusa was selected to undertake specific and detailed studies of tsunami hazard, vulnerability and damage to test existing methods and develop innovative approaches. The scope of the present work regards vulnerability and damage analyses. We chose to adopt two methods, known in the literature and briefly denoted as PTVA-3 and SCHEMA, that are based on two very different approaches, the former more qualitative and the latter more quantitative. The method PTVA-3 determines the vulnerability and damageability of a building by weighting and ranking a number of attributes covering the structural features of the edifice and the relevant characteristics of the surrounding environment such as the position with respect to the coast, the existence of defensive elements (e.g. walls, breakwaters, vegetation) and also the proximity to potential sources of floating objects that can feed damaging debris flows. On the other hand, the SCHEMA method uses a classification of building and a damage matrix that were derived from experimental fragility and damage curves first established after the Sumatra 2004 tsunami and later refined and adapted to the building stock of the Mediterranean region.

Full Text Available The study of palynomorphs and calcareous nannofossils recovered from the volcano-arenitic succession outcropping at Troina and Cerami (Sicily documents Rupelian assemblages comparable to those published for the Tusa Tuffite. This new evidence, combined with petrographic, geochemical and sedimentological affinities documented in the literature, eventually proves the genetic relationships between these units. Accordingly, the new name Troina-Tusa Formation is proposed to include all these lower Oligocene volcano-sedimentary units and to replace inappropriate names formerly used. The Troina-Tusa Formation conformably lies on a mixed siliciclastic-carbonate turbidite succession, lacking volcanic detritus, reported in the literature with different names (Polizzi Formation, Varicoloured Shales, Troina-Tusa Flysch and different ages (ranging from Eocene to Early Miocene. Palynomorphs and nannofossils recovered from its uppermost part, indicate an earliest Oligocene age. The denomination Polizzi Formation is recommended for this unit that includes also the Varicoloured Shales (Eocene-basal Oligocene. The appearance of conglomerates and volcano-arenites in the basal portion of the Troina-Tusa Formation, immediately above the top of the Polizzi Formation, marks a sudden reorganization of the Rupelian depositional systems related to the rise and erosion of a volcanic belt. Apparently, no biostratigraphically detectable hiatus is associated to this boundary. Differences in the composition of sandstones, sedimentary features and relationships with the substratum do exist between the ‘internal’ Reitano Flysch, outcropping in the type-area on the northern slope of the Nebrodi Mountains, and the volcano-arenitic successions of Cerami and Troina, reported by some authors as ‘external’ Reitano Flysch. These differences are widely documented in the literature, where the ‘internal’ Reitano Flysch is shown to lack volcanic detritus and to rest

Full Text Available The aim of this work, taking into account the last critical lesson of C.A. Madrignani, is to reflect upon how Sicily has become, through literature, a metaphor of the national political condition, and how it paradigmatically represents the inability of Italy to change. More precisely its purpose is to investigate the contribution to the construction of national identity of authors like F. De Roberto and G. Tommasi di Lampedusa, whose “anti-historical” works are characterized by a desecrating description (sometimes even polemical of the unification process of Italy. Even this illusory contradiction is part of the dimension referred to by Madrignani as the Sicily effect on Italian literature. In Viceré and Imperio (and even in the war novellas De Roberto bluntly depicts Italian history as a fierce fight for power, where human egoism prevails, which, according to a pessimistic philosophy, denies any affirmation of positive values.

Cropland versus Gariga schrubland on soil organic carbon storage under Mediterranen climatic condition of Sicily

2009-04-01

Soil organic carbon (SOC) pool is the largest among the terrestrial pool and it plays a key role to mitigate climate change. The restoration of SOC pool represents a potential sink for atmospheric CO2. Land use is one of the most important factors controlling organic carbon content. The main land uses throughout the Mediterranean are croplands (olive, wheat and vineyards) and scrublands. The land abandonment or the reclamation of land is changing the cover of scrubland and cropland. This will change the carbon cycle. The aim of this work is determining the direction and magnitude of soil organic change associated with land use change under Mediterranean Climatic Conditions. Using both historic record and land cover crop maps we estimated the effect of land cover change on the stock carbon from 1972 to 2008 in Sicily. A system of paired plots was established on Mollic Gypsiric cambisol and Gypsiric cambisol on agriculture and rangeland land uses. The study sites were selected at the natural reserve "Grotta di S. Ninfa", in the West of Sicily. Soil samples (24) were taken at 20 and 40 cm depth, air dried and sieved at 2 mm. Dry aggregate size fractions selected were >1000 µm, 1000-500 µm, 500-250 µm, 250-63 µm, 63-25 µm and <25 µm. The results show that gariga increase the organic matter in soil, mainly on the organic horizon. Key worlds: Land use change, Soil organic Carbon , Mediterranean, aggregates, gariga, cropland.

Full Text Available Background: nurses’ knowledge, attitudes and practices towards patients with HIV/AIDS are of ongoing interest, especially in developing countries. Nothing or very little is known about Italian nurses.Methods: HIV/AIDS knowledge, attitudes and behaviours of the nurses (n=107 from one university hospital inCatania,Sicily, were documented. Comparisons among nurses belonging to different Operative Units (O.U. were conducted by the chi-square test (P<0.05.Results: although HIV was nurses’ main concern in regard to contracting infections in the workplace (54%, the vast majority of them (98% had never refused an HIV/AIDS patient care assignment. Moreover, despite their concern of being more at risk of contracting HIV than the general population (41%, a not negligible percentage of nurses did not use gloves routinely (21% and only a few treated all patients as potentially HIV-positive (9%. The vast majority of the respondents knew the meaning of AIDS (87% and of a positive serological test (78%. On the contrary, a relatively low percentage of them knew what is the ‘window period’ (62% and were acquainted with HIV pathophysiology (65%. No statistically significant differences in terms of risk perception were found between nurses who had previously attended an HIV/AIDS workshop, lecture or specific course (43% and nurses who did not (57%. Level of knowledge was positively associated to age (P=0.000 and to education (P=0.016, and it was found higher in nurses working in a O.U. of Infectious Diseases.Conclusions: data from our study show that also in developed countries, such as Italy, nurses could have some misconceptions and concerns about HIV/AIDS. The importance of examining the impact of continuing education on nurses’ preparedness to care for patients with HIV/AIDS and to prevent the risks of occupational HIV transmission is discussed.

Demographic and HIV disease characteristics were recorded and assessed with the number of days accessed to our outpatients unit in univariate and multivariate analyses. The potential relationship with immunological status was also analyzed stratifying the patients into groups according to their CD4+ T-cell counts (≥500 vs <500/mm3, and ≥200 vs <200/mm3.Results: Both univariate and multivariate analyses showed that duration of antiretroviral therapy <5 years and hypertension were significantly associated with a CD4+ T-cell count of <500/mm3, whereas geographic origin (Africa was associated with a CD4+ T-cell count of <200/mm3. Mean number of days the patients sought access to day-care services for laboratory tests was negatively associated with CD4+ T-cell count.Conclusion: Patients with low CD4+ T-cell counts showed higher use of health care services, demonstrating how early HIV diagnosis can help to reduce health care costs. The CD4+ T-cell cut-off of 200 cells emphasizes the importance of identifying and managing HIV infection among hard-to-reach groups like vulnerable migrants. In our sample, the illegal status of immigrants does not influence the management of their HIV/AIDS condition, but the lack of European health card

Introduction Italy is the main recipient of asylum seekers in the European region, and Sicily is their first point of arrival. This geographical position creates a large job for Health Authorities to identify and deal with the health of immigrants. This study evaluates the prevalence of disease among asylum seekers, assessing which are associated factors. Methods A cross-sectional study was conducted to analyse demographic and clinical data in an Acceptance Centres for Asylum Seekers from February 2012 to May 2013. All variables that were found to be significant on unvariable analysis for the most frequent pathologies were included in a multivariable logistic regression model. Results Post-traumatic stress disorders with 17.4% and major depression with 7.3% were the most frequent diseases. The factors associated with post-traumatic stress disorders among asylum seekers were: major depression diagnosis (OR=2.91, p=0.004), Pakistan as a country of origin (OR=3.88, pasylum seekers needs special attention, and interventions should be done to prevent the consolidation of psychiatric morbidity. A short psychological screening after the arrival might prove helpful here. Moreover, carefully designed longitudinal studies should be carried out when political recommendations try to change the organization of psychological and healthcare services. PMID:27647085

Tsunami risk assessments in Messina, Sicily – Italy

Directory of Open Access Journals (Sweden)

A. Grezio

2012-01-01

Full Text Available We present a first detailed tsunami risk assessment for the city of Messina where one of the most destructive tsunami inundations of the last centuries occurred in 1908. In the tsunami hazard evaluation, probabilities are calculated through a new general modular Bayesian tool for Probability Tsunami Hazard Assessment. The estimation of losses of persons and buildings takes into account data collected directly or supplied by: (i the Italian National Institute of Statistics that provides information on the population, on buildings and on many relevant social aspects; (ii the Italian National Territory Agency that provides updated economic values of the buildings on the basis of their typology (residential, commercial, industrial and location (streets; and (iii the Train and Port Authorities. For human beings, a factor of time exposition is introduced and calculated in terms of hours per day in different places (private and public and in terms of seasons, considering that some factors like the number of tourists can vary by one order of magnitude from January to August. Since the tsunami risk is a function of the run-up levels along the coast, a variable tsunami risk zone is defined as the area along the Messina coast where tsunami inundations may occur.

Borrelia recurrentis, transmitted by Pediculus humanus humanus, is the etiological agent of louse-borne relapsing fever (LBRF). Currently the main focus of endemicity of LBRF is localized in East African countries. From July 2015 to October 2015, 36 cases of LBRF have been diagnosed in Europe in immigrants from the Horn of Africa. Here we report a case of LBRF with meningitis diagnosed in Florence, Italy, in an immigrant arrived from Somalia. In October 2015, a 19-year-old Somali male presented to the emergency department of the Azienda Ospedaliero Universitaria Careggi, Florence, Italy, with a 3-day history of high fever. The patient had disembarked in Sicily 10 days before admission after a long migration trip from his country of origin. On clinical examination, neck stiffness was found. Main laboratory findings were thrombocytopenia, increased procalcitonin, and increased polymorphonucleates in the cerebrospinal fluid. Suspecting a possible meningitis, the patient was treated with ceftriaxone, pending results of laboratory testing for malaria, and developed severe hypotension that was treated with fluid resuscitation and hydrocortisone. Hemoscopic testing revealed the presence of spirochetes and no malaria parasites. The patient rapidly improved with doxycycline for 7 days and ceftriaxone for 11 days, then was lost to follow-up. Total DNA from blood was extracted, and amplification and sequencing with universal 16S rDNA primers D88 and E94 revealed a 100% identity with B. recurrentis A1. LBRF is a rare but emerging infectious disease among vulnerable displaced immigrants from the Horn of Africa. Since immigrants from endemic areas can carry the vector with them, the infection should be suspected even in subjects with compatible clinical features living in the same place where new arrival immigrants are hosted. Healthcare providers should be aware of this condition to implement adequate diagnostic, therapeutic, and public health measures.

Seismogenic rotational slumps and translational glides in pelagic deep-water carbonates. Upper Tithonian-Berriasian of Southern Tethyan margin (W Sicily, Italy)

Science.gov (United States)

Basilone, Luca

2017-07-01

Soft-sediment deformation structures (SSDSs), which reflect sediment mobilization processes, are helpful to identify punctual events of paleoenvironmental stresses. In the upper Tithonian-Berriasian calpionellid pelagic limestone of the Lattimusa Fm. outcropping in the Barracù section (W Sicily), paleoenvironmental restoration reveals the occurrence of a deep-water flat basin, characterised by undeformed planar bedding, laterally passing to a gentle slope where the deformed horizons alternate with undeformed beds. Here, two types of gravity slides have been differentiated on the basis of different kinds of SSDSs, brittle deformation, involved lithofacies, geometry and morphology. Type 1 slump sheets, involving marl-limestone couplets, are characterised by chaotic stratification, truncated beds, recumbent folds, tension gashes, clastic dikes and small-scale listric normal faults and thrusts. They moved downslope as a rotational slump, displaying the typical wedge-shaped morphology, becoming thicker toe-wards. Type 2 slump sheets, involving bed packages of lime mudstone, are characterised by arcuate slump scars developing downwards as listric normal faults, associated with rotational beds and bulging. Displaying tabular geometries, they moved coherently along an overall bedding parallel detachment surface as a translational glide characterised by sediment creep. Regional geology indicates that the basin (Sicanian), bordered by a stepped carbonate platform, was affected by synsedimentary tectonics throughout the Mesozoic. The synsedimentary extensional tectonics that affect the Upper Triassic-Jurassic deposits with steeped normal faults, causing tilt-block and instability of the seafloor through fluidization processes, triggered the rotational slumps of the lower portion of the section. Seismic shocks, induced by outside sector tectonics, like those recorded in the adjacent Busambra stepped carbonate platform margin, triggered the rotational slumps that are not

performance of the tsunami predictors. The role of the local communities in defining the strategies in case of uncertain data is essential: only involvement of such communities since the beginning of the planning and implementation phase of the TEWS as well as in the definition of a decision making matrix can ensure appropriate response in case of emergency, and most importantly, the acceptance of the system in the long run. The efforts to implement the Tsunami Warning System in Italy should take into proper account the above mentioned aspects. Involvement of local communities should be primarily realized through the involvement of the local components of the Civil Protection Agency that is responsible for the implementation of the system over the Italian territory. A pilot project is being conducted in cooperation between the Civil Protection Service of Sicily and the University of Bologna (UNIBO) that contemplates the empowering of the local sea-level monitoring system (TSUNET) and specific vulnerability and risk analyses, also exploiting results of national and European research projects (e.g. TRANSFER and SCHEMA) where UNIBO had a primary role.

Kawasaki disease (KD) is an acute systemic vasculitis of small and middle size arteries; 15-25 % of untreated patients and 5 % of patients treated with intravenous immunoglobulin (IVIG) develop coronary artery lesions (CAL). Many studies tried to find the most effective treatment in the management of resistant KD and to select the risk factors for CAL. Our data are assessed on children from west Sicily, characterized by a genetic heterogeneity. We studied the clinical data of 70 KD Sicilian children (36 males: 51 %; 34 females: 49 %), analysed retrospectively, including: demographic and laboratory parameters; echocardiographic findings at diagnosis, at 2, 6 and 8 weeks, and at 1 year after the onset of the illness. Forty-seven had Typical KD, three Atypical KD and twenty Incomplete KD. Age at the disease onset ranged from 0.1 to 8.9 years. IVIG were administered 5 ± 2 days after the fever started. Defervescence occurred 39 ± 26 hours after the first IVIG infusion. Fifty-six patients (80 %) received 1 dose of IVIG (responders); 14 patients (20 %) had a resistant KD, with persistent fever after the first IVIG dose (non responders). Ten (14 %) non responders responded to the second dose, 4 (5 %) responded to three doses; one needed treatment with high doses of steroids and Infliximab. Cardiac involvement was documented in twenty-two cases (eighteen with transient dilatation/ectasia, fifteen with aneurysms). Pericardial effusion, documented in eleven, was associated with coronaritis and aneurysms, and was present earlier than coronary involvement in seven. Hypoalbuminemia, D-dimer pre-IVIG, gamma-GT pre-IVIG showed a statistically significant direct correlation with IVIG doses, highlighting the role of these parameters as predictor markers of refractory disease. The persistence of elevated CRP, AST, ALT levels, a persistent hyponatremia and hypoalbuminemia after IVIG therapy, also had a statistical significant correlation with IVIG doses. Non responders

INTEGRATED STRATIGRAPHY FROM THE CONTRADA FORNAZZO SECTION, MONTE INICI, WESTERN SICILY, ITALY: PROPOSED G.S.S.P. FOR THE BASAL BOUNDARY OF THE TITHONIAN STAGE

Directory of Open Access Journals (Sweden)

GIULIO PAVIA

2004-03-01

Full Text Available This paper deals with a definition of the lower boundary stratotype of the Tithonian Stage in the Upper Jurassic succession of Monte Inici, Western Sicily. The upper member of the Rosso Ammonitico Fm. is 27 m thick and shows a typical nodular-calcareous lithofacies; its lower beds have been sampled for biostratigraphic and paleomagnetic purposes. Though the succession is affected by high stratigraphic condensation, the resulting hiatuses have been shown to be below biochronological resolution and thus do not hinder any biostratigraphic definition. The biostratigraphic analysis has been based on the rich ammonite assemblages in which the common genus Hybonoticeras is the index-key for characterizing the Kimmeridgian-Tithonian boundary. Four ammonite biozones have been identified; the basal Tithonian one is defined by the assemblage of Hybonoticeras gr. hybonotum and Haploceras staszycii. The recorded calcareous nannofossil bioevents allow recognition of the V. stradneri and C. mexicana Zones, whose boundary is located a little below the identified Tithonian lower boundary. The paleomagnetic record shows normal polarity in the S. darwini/V. albertinum Zone and mainly reverse polarity in the H. beckeri and H. hybonotum Zones, with three minor normal polarity intervals; the lower boundary of the Tithonian falls in the oldest of these intervals. The integrated multidisciplinary stratigraphic information gathered from the Contrada Fornazzo section defines the lower boundary of the H. hybonotum Zone at the base of Bed 110, and supplies elements of chrono-correlation sufficient to regard this section as a possible G.S.S.P. of the Tithonian Stage.

Full Text Available Afforestation and reforestation activities in Sicily have been widespreaded in the last century. The results of forestation activities indicate the need to adopt a operational tools to promote the extension of forest surface at regional and sub-regional levels. In this view, with the aim to produce useful tools for forest plantation planning, the entire regional area was analysed and ecologically homogeneous areas have been identified to join and target arboriculture and/or forestation plantation activities, to choose tree and shrub species for different environments and to identify priority areas of intervention. The map of Rivas-Martinez bioclimate and the map of litological types were used as basic information layers to map pedo-climatic homogeneous areas. In order to mitigate disruptive hydrogeological effects and to reduce desertification risk and forest fragmentation, the Corine Land Cover map (CLC2000, the hydrogeological bond map and the desertification risk map were used to identify areas characterized by urgent need of forest activities at high priority level. A total of 23 ecologically homogeneous areas have been identified in Sicily, while more than a quarter of the regional surface has been characterized as highest priority intervention level. At sub-regional level, the target of the analysis was carried out at administrative province and at hydrographic basin level.

In the Ionian Sea (central Mediterranean) the slow convergence between Africa and Eurasia results in the formation of a narrow subduction zone. The nature of the crust of the subducting plate remains debated and could represent the last remnants of the Neo-Tethys ocean. The origin of the Ionian basin is also under discussion, especially concerning the rifting mechanisms as the Malta Escarpment could represent a remnant of this opening. This subduction retreats toward the south-east (motion occurring since the last 35 Ma) but is confined to the narrow Ionian basin. A major lateral slab tear fault is required to accommodate the slab roll-back. This fault is thought to propagate along the eastern Sicily margin but its precise location remains controversial. This study focuses on the deep crustal structure of the eastern Sicily margin and the Malta Escarpment. We present two two-dimensional P wave velocity models obtained from forward modeling of wide-angle seismic data acquired onboard the R/V Meteor during the DIONYSUS cruise in 2014. The results image an oceanic crust within the Ionian basin as well as the deep structure of the Malta Escarpment, which presents characteristics of a transform margin. A deep and asymmetrical sedimentary basin is imaged south of the Messina strait and seems to have opened between the Calabrian and Peloritan continental terranes. The interpretation of the velocity models suggests that the tear fault is located east of the Malta Escarpment, along the Alfeo fault system.

The essay examines the case of the documented beginnings of a dynasty of master builders (in south-east Sicily in the mid 16th century): the Odierna family. The brevity and incompleteness of the sources lead to an initial, superficial interpretation; a simple artisan dimension with little real information. However, it requires an additional - deeper interpretation to grasp the true picture - of the first modern age of the Island. After the 1542 earthquake, a multi-disciplinary study of the su...

Geochemistry and habitat of the oils in Italy

Energy Technology Data Exchange (ETDEWEB)

Mattavelli, L.; Novelli, L. (Agip S.p.A., Milano (Italy))

1990-10-01

All varieties of liquid petroleum, ranging from condensates (> 50{degree}API) to immature sulfur-rich heavy oils (as low as 5{degree} API), have been found in Italy. However, nonbiodegraded heavy oils account for about 70% of the total original oil in place. Geochemical analyses indicate that 11 oil groups are present in the Italian basins and two main types of source rocks have been identified: Triassic carbonates and Tertiary shales. About 95% of the oils were originated from Middle and Upper Triassic carbonates containing type II kerogen (about 1% total organic carbon (TOC) and 500 mg hydrocarbon/g TOC). Only a relatively minor amount of oil was generated by Tertiary shales containing type III kerogen with TOC generally less than 1%. Timing of generation and migration and bulk properties of oils were controlled by geodynamic histories of the three main Italian geologic settings: (1) Apennine and Southern Alp thrust belts, (2) foredeep (depression bordering the thrust belts), and (3) foreland (nondeformed African continental margin). Within the Apennine thrust belts, deep burial during the Neogene resulted in the generation of substantially lighter oils, not only from deeply buried Triassic but sometimes also from Tertiary source rocks. In the late Neogene, foredeep depocenters located in the central Adriatic and southern Sicily, high subsidence (up to 1,000 m/m.y.), a low geothermal gradient (22C/km) and compressional tectonics caused the generation of immature heavy oils generally at depths below 5,000 m and temperatures greater than 100C. Rapid burial and higher geothermal gradients (32C/km), which occurred since the Jurassic, resulted in the generation of light oils from the Late Cretaceous to the Oligocene in the southern sector of Adriatic foreland.

Catania lies on the eastern coast of Sicily and is one of the most important towns in Sicily as regards history, tourism and industry. Recent analyses conducted in the frame of the project TRANSFER have shown that it is exposed not only to tsunamis generated locally, but also to distant tsunamis generated in the western Hellenic arc. In the frame of the European project SCHEMA different scenarios covering local sources such as the 11 January 1693 event and the 1908 case as well as remote sources such as the 365 AD tsunami have been explored through numerical modelling in order to assess the vulnerability of the area to tsunami attacks. One of the primary outcomes of the scenario analysis is the quantification of the inundation zones (location, extension along the coast and landward). Taking the modelling results on flooding as input data, the analysis has focussed on the geomorphological characteristics of the coasts and on the buildings and infrastructure typology to make evaluation of the vulnerability level of the Catania area. The coast to the south of the harbour of Catania is low and characterized by a mild slope: topography reaches the altitude of 10 m between 300-750 m distance from the shoreline. Building density is low, and generally tourist structures prevail on residential houses. The zone north of the harbour is high-coast, with 10 m isoline usually close to the coastline, and little possibility for flood to penetrate deep inland. Here there are three small marinas with the corresponding services and infrastructure around, and the city quarters consists of residential buildings. Vulnerability assessment has been carried out by following the methodology developed by the SCHEMA consortium, distinguishing between primary (type and material) and secondary criteria (e.g. ground, age, foundation, orientation, etc.) for buildings, and by adopting a building damage matrix, basically depending on building type and water inundation depth. Data needed for such

Bonanno, Giuseppe; Lo Giudice, Rosa; Pavone, Pietro

2012-08-01

Trace element impact was assessed using mosses in a densely inhabited area affected by mud volcanoes. Such volcanoes, locally called Salinelle, are phenomena that occur around Mt. Etna (Sicily, Italy) and are interpreted as the surface outflow of a hydrothermal system located below Mt. Etna, releasing sedimentary fluids (hydrocarbons and NaCl brines) along with magmatic gases (mainly CO(2) and He). To date, scarce data are available about the presence of trace elements, and no biomonitoring campaigns are reported about the cumulative effects of such emissions. In this study, concentrations of Al, As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, V, and Zn were detected in the moss Bryum argenteum, in soil and water. Results showed that the trace element contribution of the Salinelle to the general pollution was significant for Al, Mn, Ni, and Zn. The comparison of trace concentrations in mosses from Salinelle and Etna showed that the mud volcanoes release a greater amount of Al and Mn, whereas similar values of Ni were found. Natural emissions of trace elements could be hazardous in human settlements, in particular, the Salinelle seem to play an important role in environmental pollution.

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

Directory of Open Access Journals (Sweden)

2011-08-01

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

Italy in Postcolonial Discourse

Directory of Open Access Journals (Sweden)

Concilio, Carmen

2016-12-01

Full Text Available In this essay, I would like to explore the representations of Italy through the eyes of three outstanding postcolonial writers: Jhumpa Lahiri, Michael Ondaatje and Nuruddin Farah. Even though Italy is an oasis of art and culture, Jhumpa Lahiri looks at it with a profound sense of both admiration and sadness in Hema and Kaushik (2008. Her scrutiny of the ancient, pre-imperial ruins of the Etruscan period leads her characters to question life, death and marital life. Similarly, Ondaatje opposes an Italian Renaissance villa to the debris left behind by war in his well-known The English Patient (1992. His Punjabi character Kirpal Singh mentions Gabicce Mare, a place that soon after World War II will become a memorial and cemetery for the Indian troops who fought and died for the liberation of Italy. This discourse is picked up by Helena Janaczeck, a Polish-Italian writer who combines a narrative on Polish migration in Italy with an elegiac narrative about the cemetery and memorial in Cassino, where a Maori goes to visit the tombs of his ancestor, who also participated with the Commonwealth troops in World War II. Nuruddin Farah too, who provides a reportage on Somali immigrants to Italy, seems to consider the country as a springboard either to other North European destinations or to a possible destiny back home. All three writers present Italy according to varied and unusual perspectives.

The molluscan fauna is represented by poor to rich-species assemblages of land and freshwater gastropods and bivalves with Mediterranean-European character. Some species have been found for the first time as fossils in Sicily. The land snails prevail in the 1998 trench showing a persistent arid environment during the time of the sediment deposition. The freshwater species, characteristic of slow-running water, point to the presence of a small water body (stream or spring inside the cave, probably more consistent in the 2002-2004 trench where this fauna prevails. The dispersal of the molluscan fauna of S. Teodoro Cave from the mainland during the low stand sea-level phases of the upper Pleistocene probably belongs to the same dispersal events following the Oxygen Isotope Stage 5e which introduced into the island not endemic faunal elements which are associated with endemic faunal elements in S. Teodoro Cave. Littoral marine reworked molluscs found in the cave deposits probably come from the sedimentary cover of a middle Pleistocene terrace which overlies the roof of the cave. SHORT NOTE

Full Text Available This issue is about our Human Papilloma Virus (HPV DNA test. We have examined two cohorts of patients from south-central Sicily, who were tested for HPV -DNA derived from cervical sampling, respectively in 2003 and 2011. In 2003, the most represented genotypes were: 31, 16. Instead, in 2011 there was a higher prevalence for genotypes: 42, 16. It is remarkable to note that the 35 genotype, noticed in 2003, has never been found in the second most recent group.

Full Text Available The recent decision to convert the Benedictine Dormitory in Monreale into an exhibition site offers the opportunity to enjoy the whole monumental complex where the wonderful cloister is the core attraction. It is on this site that the Norman Cathedral stands, brightly decorated with golden mosaics. The new exhibition has gathered together the artworks from the ruined abbey of Santa Maria del Bosco in Calatamauro and added them to the artefacts already exhibited at the Diocesan Museum. They include marble gravestones from the 16th-17th century church and those dating to the 18th century; one stone is in polychrome marble of the family of the canons, Candes and Donato; another was used for the burial of the monks from the period of the Olivetan refoundation, characterized by the Order’s coat of arms and attributed to Girolamo Musca. There are also majolica tiles from the chapels in cornu evangelij (left side of the altar adorned with large vegetal-shaped decorations, provided by Palermitan manufacturers in the mid-eighteenth century. They are found next to the remnants of the majolica tiles still in situ, executed in 1762 by the potters from Burgio, in Sicily. Rosario Rosso (also Russo and Giuseppe Virgadamo. Also commissioned after the refoundation of the holy temple are the four artworks by the painter Ippolito Ferrante, three of which, Sacrificio di Isacco, Melchisedec and Giale e Sisar, are on exhibition in the prestigious museum. Alongside these artworks are noteworthy textile artefacts made between the second half of the 16th and second half of the 18th centuries some of which are linked to the munificent figures of archbishops such as Ludovico II Torres and Francesco Testa.

Quantifying probabilities of eruptions at Mount Etna (Sicily, Italy).

Science.gov (United States)

Brancato, Alfonso

2010-05-01

One of the major goals of modern volcanology is to set up sound risk-based decision-making in land-use planning and emergency management. Volcanic hazard must be managed with reliable estimates of quantitative long- and short-term eruption forecasting, but the large number of observables involved in a volcanic process suggests that a probabilistic approach could be a suitable tool in forecasting. The aim of this work is to quantify probabilistic estimate of the vent location for a suitable lava flow hazard assessment at Mt. Etna volcano, through the application of the code named BET (Marzocchi et al., 2004, 2008). The BET_EF model is based on the event tree philosophy assessed by Newhall and Hoblitt (2002), further developing the concept of vent location, epistemic uncertainties, and a fuzzy approach for monitoring measurements. A Bayesian event tree is a specialized branching graphical representation of events in which individual branches are alternative steps from a general prior event, and evolving into increasingly specific subsequent states. Then, the event tree attempts to graphically display all relevant possible outcomes of volcanic unrest in progressively higher levels of detail. The procedure is set to estimate an a priori probability distribution based upon theoretical knowledge, to accommodate it by using past data, and to modify it further by using current monitoring data. For the long-term forecasting, an a priori model, dealing with the present tectonic and volcanic structure of the Mt. Etna, is considered. The model is mainly based on past vent locations and fracture location datasets (XX century of eruptive history of the volcano). Considering the variation of the information through time, and their relationship with the structural setting of the volcano, datasets we are also able to define an a posteriori probability map for next vent opening. For short-term forecasting vent opening hazard assessment, the monitoring has a leading role, primarily based on seismological and volcanological data, integrated with strain, geochemical, gravimetric and magnetic parameters. In the code, is necessary to fix an appropriate forecasting time window. On open-conduit volcanoes as Mt. Etna, a forecast time window of a month (as fixed in other applications worldwide) seems unduly long, because variations of the state of the volcano (significant variation of a specific monitoring parameter could occur in time scale shorter than the forecasting time window) are expected with shorter time scale (hour, day or week). This leads to set a week as forecasting time window, coherently with the number of weeks in which an unrest has been experienced. The short-term vent opening hazard assessment will be estimated during an unrest phase; the testing case (2001 July eruption) will include all the monitoring parameters collected at Mt. Etna during the six months preceding the eruption. The monitoring role has been assessed eliciting more than 50 parameters, including seismic activity, ground deformation, geochemistry, gravity, magnetism, and distributed inside the first three nodes of the procedure. Parameter values describe the Mt. Etna volcano activity, being more detailed through the code, particularly in time units. The methodology allows all assumptions and thresholds to be clearly identified and provides a rational means for their revision if new data or information are incoming.

Elastic recoil spectrometry induced by 3 MeV helium-4 microbeam has been used to determine hydrogen distribution within melt inclusions trapped in quartz. These minerals were selected from different geological environments: Guadeloupe (West Indies), Pantelleria Island (South Sicily - Italy) and San Pietro (South Sardinia - Italy). Bulk hydrogen contents are calculated (H assumed to be in H 2 O form). The knowledge of hydrogen distribution assists both in a better understanding and in the establishment of volcanic dynamism hypotheses. Finally, fluid hydrogen rich inclusions are evidenced and H concentration profile is simulated and reported for the first time in glass inclusion

KM3NeT is a deep-sea research infrastructure being constructed in the Mediterranean Sea. It will be installed at three sites: KM3NeT-Fr, offshore Toulon, France, KM3NeT-It, offshore Portopalo di Capo Passero, Sicily (Italy) and KM3NeT-Gr, offshore Pylos, Peloponnese, Greece. It will host the next generation Cherenkov neutrino telescope and nodes for a deep sea multidisciplinary observatory, providing oceanographers, marine biologists, and geophysicists with real time measurements. The neutrino telescope will search for Galactic and extra-Galactic sources of neutrinos, complementing IceCube in its field of view. The detector will have a modular structure and consists of six building blocks, each including about one hundred Detection Units (DUs). Each DU will be equipped with 18 multi-PMT digital optical modules. The first phase of construction has started and shore and deep-sea infrastructures hosting the future KM3NeT detector are being prepared in France near Toulon and in Italy, near Capo Passero in Sicily. The technological solutions for KM3NeT and the expected performance of the detector are presented and discussed

Between June 2011 and September 2013, the Nebrodi Mountains region was affected by a seismic swarm consisting of > 2700 events with local magnitude 1.3 ≤ ML ≤ 4.6 and located in the 5-9 km depth interval. The seismic swarm defines a seismogenetic volume elongated along the E-W direction and encompasses the NW-SE-oriented tectonic boundary between the Calabrian arc (north-eastward) and the Sicilide units (south-westward). By exploring the recent tectonic deformation and the seismic behavior of the region, this study aims at providing additional constraints on the seismogenetic faults at the southern termination of the Calabrian arc. Waveform similarities analysis allowed observing that 45% of the whole dataset can be grouped into six different families of seismic events. Earthquake multiplet families are mainly located in the eastern part of the seismogenetic volume. We suggest that such a feature is responsive to the lateral lithological variations as highlighted by geology (at the surface) and P-wave seismic tomography (at depth of 10 km). Stress tensor inversions performed on FPSs indicate that the investigated region is currently subject to a nearly biaxial stress state in an extensional regime, such that crustal stretching occurs along both NW-SE and NE-SW directions. Accordingly, mesoscale fault geometries and kinematics analyses evidence that a younger normal faulting stress regime led to a tectonic negative inversion by replacing the pre-existing strike-slip one. Based on our results and findings reported in recent literature, we refer such a crustal stretching to mantle upwelling process (as evidenced by diffuse mantle-derived gas emissions) coupled with a tectonic uplift involving north-eastern Sicily since Middle Pleistocene. Moreover, seismic swarms striking the region would be related to the migration of mantle and sub-crustal fluids toward the surface along the complex network of tectonic structures cutting the crust and acting as pathways.

Potential biogas production from agricultural by-products in Sicily. A case study of citrus pulp and olive pomace

Directory of Open Access Journals (Sweden)

Francesca Valenti

2017-07-01

Full Text Available Renewable energy sources represent a suitable alternative to conventional fossil fuels, due to the possible advantages in terms of environmental impact reduction. Anaerobic digestion of biomasses could be considered an environmental friendly way to treat and revalorise large amounts of by-products from farming industries because it ensures both pollution control and energy recovery. Therefore, the objective of this study was to define a methodology for evaluating the potential biogas production available from citrus pulp and olive pomace, which are suitable agricultural by-products for biogas production. In the first phase of the study, the spatial distribution of both olive and citrus-producing areas was analysed in Sicily, a geographical area of the Mediterranean basin highly representative of these types of cultivation. Then, a GIS-based model, which had been previously defined and utilised to evaluate the amount of citrus pulp and olive pomace production, was applied to this case study. Based on the results obtained for the different provinces of Sicily, the province of Catania was chosen as the study area of this work since it showed the highest production of both citrus pulp and olive pomace. Therefore, a further analysis regarded the quantification of olive pomace and citrus pulp at municipal level. The results of this analysis showed that the total amount of available citrus pulp and olive pomace corresponded theoretically to about 11,102,469 Nm3/year biogas. Finally, the methodology adopted in this study made it possible to identify suitable areas for the development of new biogas plants by considering both the spatial distribution of the olive and citrus growing areas and the locations of the existing processing industries.

Fatto in Italia: Refashioning Italy

Directory of Open Access Journals (Sweden)

Tiziana Ferrero-Regis

2008-09-01

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.

Astronomical calibration of Gauss to Matuyama sapropels in the Mediterranean and implication for the Geomagnetic Polarity Time Scale

Hilgen, F. J.

1991-06-01

The astronomically calibrated age of the Olduvai Subchron is established by correlating the cyclic sapropel patterns in the Vrica section and in the sections of Semaforo (Italy), Singa (Italy), Punta Piccola (Sicily), and Francocastello (Crete) to the new astronomical solutions for the precession of the equinox and eccentricity of the earth's orbit, using inferred phase relationships between the sapropel cycles and orbital cycles. The resultant ages for the Olduvai and for older boundaries are then compared with conventional, as well as other orbitally tuned ages, for these polarity transitions. It is shown that this astronomically calibrated time scale can be extended back to the Miocene/Pliocene boundary.

Pollen-based reconstruction of Holocene vegetation and climate in southern Italy: the case of Lago Trifoglietti

Directory of Open Access Journals (Sweden)

S. Joannin

2012-12-01

Full Text Available A high-resolution pollen record from Lago Trifoglietti in Calabria (southern Italy provides new insights into the paleoenvironmental and palaeoclimatic changes which characterise the Holocene period in the southern Italy. The chronology is based on 11 AMS radiocarbon dates from terrestrial organic material. The Holocene history of the vegetation cover shows the persistence of an important and relatively stable Fagus forest present over that entire period, offering a rare example of a beech woodstand able to withstand climate changes for more than 11 000 yr. Probably in relation with early Holocene dry climate conditions which affected southern Italy, the Trifoglietti pollen record supports a southward delay in thermophyllous forest expansion dated to ca. 13 500 cal BP at Monticchio, ca. 11 000 cal BP at Trifoglietti, and finally ca. 9800 cal BP in Sicily. Regarding the human impact history, the Trifoglietti pollen record shows only poor imprints of agricultural activities and anthopogenic indicators, apart from those indicating pastoralism activities beneath forest cover. The selective exploitation of Abies appears to have been the strongest human impact on the Trifoglietti surroundings. On the basis of (1 a specific ratio between hygrophilous and terrestrial taxa, and (2 the Modern Analogue Technique, the pollen data collected at Lago Trifoglietti led to the establishment of two palaeoclimatic records tracing changes in (1 lake depth and (2 annual precipitation. On a millennial scale, these records give evidence of increasing moisture from ca. 11 000 to ca. 9400 cal BP and maximum humidity from ca. 9400 to ca. 6200 cal BP, prior to a general trend towards the drier climate conditions that have prevailed up to the present. In addition, several successive centennial-scale oscillations appear to have punctuated the entire Holocene.

Full Text Available In order to achieve the ambitious objective of decarbonising the economy, it is mandatory, especially in Europe and in Italy, to include the retrofitting of existing buildings. In a country where a large share of existing buildings have heritage value, it is important to design effective retrofit solutions also in historical buildings. In this context, the paper describes the experience of re-design of an existing rural building located in Sicily, inside the ancient Greeks' “Valley of the Temples”. An energy audit was performed on the building, and its energy uses were thoroughly investigated. A building model was developed in the TRNSYS environment and its performances validated. The validated model was used for redesign studies aimed towards the achievement of the Net Zero Energy Building target. The best performing solutions to be applied to a case study like the Sanfilippo House were those regarding the management of the building, as in the case of the natural ventilation and the energy systems setpoints, that would allow a large impact (up to 10% reductions in energy uses on the energy performances of the building with no invasiveness, and those with very limited invasiveness and high impact on the energy efficiency of the building, as in the lighting scenario (up to 30% energy uses reduction. The most invasive actions can only be justified in the case of high energy savings, as in the case of the insulation of the roof, otherwise they should be disregarded.

In summer 2012 the Italian EU-UNAWE team joined with the South African team in Cape Town, working with the township schools organizing activities at school and also a teachers' training event at the SAAO Observatory. In order to involve in the exchange not only the project's experts but also to the teachers and the children, we organized Skype connections between the Cape town teachers participating in the project and the teachers in Sicily (South Italy) that also participated in one of the Italian training sessions and later between the children of the Italian school and those in Zanemfundo School (Cape Town). Thanks to this chance of seeing each other and talking directly, children have - with huge interest and participation - shared and learned methods, experiences, curiosities. They shared their prepared actual science researches, in order to understand why an equal gnomon cast different shadows at the same time in the two countries. The teachers confronted on curricula, didactic methodologies such as working with a background story during the whole school year, interdisciplinary uses of astronomy, languages etc. The EU-UNAWE project and International or Regional conferences such as LARIM are perfect chances to create exchanges between countries all around the World, and this simple communication model between children and teachers appears like an enormous resource yet to be fully exploited.

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

Full Text Available Abstract This paper pays attention to the modifiable lifestyle factors such as diet and nutrition that might influence life extension and successful ageing. Previous data reported that in Sicily, the biggest Mediterranean island, there are some places where there is a high frequency of male centenarians with respect to the Italian average. The present data show that in Sicani Mountain zone there are more centenarians with respect to the Italian average. In fact, in five villages of Sicani Mountains, there were 19 people with an age range of 100–107 years old from a total population of 18,328 inhabitants. So, the centenarian number was 4.32-fold higher than the national average (10.37 vs. 2.4/10,000; the female/male ratio was 1.1:1 in the study area, while the national ratio is 4.54:1. Unequivocally, their nutritional assessment showed a high adherence to the Mediterranean nutritional profile with low glycemic index food consumed. To reach successful ageing it is advisable to follow a diet with low quantity of saturated fat and high amount of fruits and vegetables rich in phytochemicals.

In 2015, Italy was the second most common point of entry for asylum seekers into Europe after Greece. The vast majority embarked from war-torn Libya; 80,000 people claimed asylum that year. Their medical conditions were assessed on arrival but their mental health needs were not addressed in any way, despite the likelihood of serious trauma before and during migration. Médecins sans Frontières (MSF), in agreement with the Italian Ministry of Health, provided mental health (MH) assessment and care for recently-landed asylum seekers in Sicily. This study documents mental health conditions, potentially traumatic events and post-migratory living difficulties experienced by asylum seekers in the MSF programme in 2014-15. All asylum seekers transiting the 15 MSF-supported centres were invited to a psycho-educational session. A team of psychologists and cultural mediators then provided assessment and care for those identified with MH conditions. Potentially traumatic events experienced before and during the journey, as well as post-migratory living difficulties, were recorded. All those diagnosed with MH conditions from October 2014 to December 2015 were included in the study. Among 385 individuals who presented themselves for a MH screening during the study period, 193 (50%) were identified and diagnosed with MH conditions. Most were young, West African males who had left their home-countries more than a year prior to arrival. The most common MH conditions were post traumatic stress disorder (31%) and depression (20%). Potentially traumatic events were experienced frequently in the home country (60%) and during migration (89%). Being in a combat situation or at risk of death, having witnessed violence or death and having been in detention were the main traumas. Lack of activities, worries about home, loneliness and fear of being sent home were the main difficulties at the AS centres. MH conditions, potentially traumatic events and post-migratory living difficulties are

Nuclear decommissioning in Italy

International Nuclear Information System (INIS)

Tripputi, I.

Italy is in a unique position. Italy has been in the past among the leading countries in the pacific use of nuclear energy, but, as a consequence of the 1987 referendum decided to shutdown all operating power plants, to leave uncompleted the plants under construction and to stop all related research and industrial activities declaring a 5 years moratorium on any future initiative. The moratorium ended unnoticed in 1992, since there was no political move to restart nuclear power in Italy and, in practice, it is still acting. Therefore, now the major efforts in the nuclear field are focused on the closure of past liabilities assuring safety and security highest levels. This is a duty to be carried out by the generation that used this form of energy, but, at least for somebody, also a precondition for the acceptance of any future renaissance of nuclear energy in Italy. SOGIN is a Company carrying out a service for the country and fully committed to solve the liabilities left by the interrupted nuclear industry in Italy. To this aim SOGIN is managed as a private company to assure the highest possible efficiency, but, at the same time, is driven by moral and ethical objectives and the vision of protecting the environment and health and safety of the public. SOGIN blends in a synergic way the various ENEL experiences (design and operation of NPP's) and ENEA experiences (engineering and operation of R and D and industrial facilities supporting NPP's). Such a comprehensive combination of technical competences should not be dispersed in the medium and long term and the management is committed to facilitate the technical growth of the impressing number of motivated young people joining the Company, whose enthusiasm is contaminating every day also the 'veterans', to assure for the country an asset and a presidium of very specialized multi-disciplinary nuclear competences. Speaking of possible scenarios for the future, we should mention that the current international situation

The Messinian salinity crisis is a dramatic hydrological and biological crisis that occurred in the Mediterranean basin at 5.97-5.33 Ma. The interpretation of the facies and stratigraphic associations of the Messinian salt deposits is still the object of active research because of the absence of modern depositional analogues of comparable scale. In this study, the spatial distributions of Na, Mg, S, O, Si, and Al in a potassic-magnesian salt and a halite layers of Messinian evaporites from the Realmonte mine on Sicily were determined using synchrotron based micro-X-ray fluorescence. The dominant molecular host site of Mg and S obtained by X-ray absorption near edge structure (XANES) is applied to specify the hydrochemistry of hypersaline brines and the presence of diagenetic minerals, thus shedding light on evaporative concentration processes in the Caltanissetta Basin of Sicily. Mg and S K-edge XANES spectra revealed the presence of highly soluble Mg-bearing sulfates. The massive halite layer "unit C," contains less soluble minerals, thus did not exceed the stage of halite crystallization. We infer that as evaporative concentration increased, the density of the brine at the shallow margin of the basin increased as salinity increased to concentrations over 70 times the starting values, creating brines that were oversaturated with Mg-sulfate. Density stratification of the deep basin caused heavy brines to sink to the bottom and become overlain by more dilute brines. We propose lateral advection of dense Mg-sulfate brines that certainly affected marine biota.

The stock of organic carbon in the soil (SOC) is an indicator of soil ability to support agro-ecosystems productivity and resilience to environmental changes (Schillaci et al. 2016; 2017). In addition, SOC stock change through space and especially time is a valuable indicator of the soil ability to sequester CO2 from the atmosphere and thus its potential to reduce the greenhouse gas effect. In the present work, we mapped (1-km resolution) the space-time variation of the SOC stock after 15 years (1993 to 2008) in a semi-arid Mediterranean area (25,286 km2) after modelling SOC concentration (0-0.4 m depth) with boosted regression trees (BRT) and computing the SOC stock after the application of the bulk density maps of ISRIC (soilgrid.com, Hengl et al., 2014). The area under study (Sicily, south of Italy) has a plenty of contrasting environments, with changing ecosystems, soils, and microclimatic regions. The BRT procedure was run with a set of 25 predictors per year, including land use, soil traits, morphometric indicators and remote sensing covariates (derived from Landsat5 data). The BRT output consisted of a high pseudo-R2(=0.71 for 1993 and 0.63 for 2008) of the SOC concentration, low uncertainty (standard deviation doi:10.1016/j.geoderma.2016.10.

Voyages of a successful text. The Dialogi of Gregory the Great in Medieval Sicily (XII-XIV Century

Rossana Barcellona

2013-10-01

Full Text Available This essay reconstructs two “Sicilian chapters” of great success from the Dialogi by Gregorius Magnus which were enjoyed in the medieval era. These are the legend of Placido (Placido is a Benedict's young disciple mentioned in the Dialogi, which has Sicily as a background, as recounted by Pietro, Deacon of Montecassino between the XI and the XII centuries, and the Sicilian vulgarization of the work, carried out by Giovanni Campolo in the first half of the XIV century. The literary voyage of Placido and the work of Campolo are two excellent examples of the circulation and the fruition of an exemplary and authoritative text. Each highlights the complex intricacy of religion, culture and politics in the various systems of power and in the various historical settings that the medieval age explored.

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.)

Panzera, Francesco; D'Amico, Sebastiano; Lombardo, Giuseppe; Longo, Emanuela

2016-07-01

The Siracusa area, located in the southeastern coast of Sicily (Italy), is mainly characterized by the outcropping of a limestone formation. This lithotype, which is overlain by soft sediments such as sandy clays and detritus, can be considered as the local bedrock. Records of ambient noise, processed through spectral ratio techniques, were used to assess the dynamic properties of a sample survey of both reinforced concrete and masonry buildings. The results show that experimental periods of existing buildings are always lower than those proposed by the European seismic code. This disagreement could be related to the role played by stiff masonry infills, as well as the influence of adjacent buildings, especially in downtown Siracusa. Numerical modeling was also used to study the effect of local geology on the seismic site response of the Siracusa area. Seismic urban scenarios were simulated considering a moderate magnitude earthquake (December 13th, 1990) to assess the shaking level of the different outcropping formations. Spectral acceleration at different periods, peak ground acceleration, and velocity were obtained through a stochastic approach adopting an extended source model code. Seismic ground motion scenario highlighted that amplification mainly occurs in the sedimentary deposits that are widespread to the south of the study area as well as on some spot areas where coarse detritus and sandy clay outcrop. On the other hand, the level of shaking appears moderate in all zones with outcropping limestone and volcanics.

Group Psychotherapy in Italy.

Giannone, Francesca; Giordano, Cecilia; Di Blasi, Maria

2015-10-01

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

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.

Historically, Mangifera indica L. cultivations have been widely planted in tropical areas of India, Africa, Asia, and Central America. However, at least 20 years ago its spreading allowed the development of some cultivars in Sicily, an island to the south of Italy, where the favourable subtropical climate and adapted soils represent the perfect field to create new sources of production for the Sicilian agricultural supply chain. Currently, cultivations of Kensington Pride, Keitt, Glenn, Maya, and Tommy Atkins varieties are active in Sicily and their products meet the requirements of local and European markets. Mango plants produce fleshy stone fruits rich in phytochemicals with an undisputed nutritional value for its high content of polyphenolics and vitamins. This review provides an overview of the antioxidant, anti-inflammatory, and anticancer properties of mango, a fruit that should be included in everyone's diet for its multifaceted biochemical actions and health-enhancing properties.

The project Surveillance of rare cancers in Italy (RITA) provides, for the first time, estimates of the burden of rare cancers in Italy based on the list of rare cancers proposed in collaboration with the European project Surveillance of Rare Cancers in Europe (RARECARE). RITA analyzed data from Italian population-based cancer registries (CR). The period of diagnosis was 1988 to 2002, and vital status information was available up to December 31, 2003. Incidence rates were estimated for the period 1995-2002, survival for the years 2000-2002 (with the period method of Brenner), and complete prevalence at January 1, 2003. Rare cancers are those with an incidence <6/100,000/year. In Italy, every year there are 60,000 new diagnoses of rare cancers corresponding to 15% of all new cancer diagnoses. Five-year relative survival was on the average worse for rare cancers (53%) than for common cancers (73%). A total of 770,000 patients were living in Italy in 2008 with a diagnosis of a rare cancer, 22% of the total cancer prevalence. Our estimates constitute a useful base for further research and support the idea that rare cancers are a public health problem that deserves attention. Centers of expertise for rare cancers that pool cases, expertise and resources could ensure an adequate clinical management for these diseases. Our data also showed that cancer registries are suitable sources of data to estimate incidence, prevalence and survival for rare cancers and should continue to monitoring rare cancers in Italy.

Exposure of children to passive tobacco smoking in the household setting has been demonstrated to cause respiratory diseases. Early atherosclerosis has also been demonstrated in young people previously exposed to passive tobacco smoking. Functional damage can initiate at the fetal age due to maternal smoking, with a tendency towards over-time progress. To date only scant data are available about indoor parental smoking attitudes and their changes after campaigns against smoke and risk factors in exposed youths. Questionnaires are useful tools in order to search for information on cigarette smoking and parental household lifestyle. In this study, we asked pupils of primary schools for providing information on their relatives' every 5 years throughout the period 1994-2009. A multiple-choice answer questionnaire about sharing household parental smoking was administered to all primary school children (mean age 10.5 ± 0.5 years) of the city of Agrigento (Sicily, Italy). A total of 2221 questionnaires were collected from 637 children in 1994, 687 in 1999, 516 in 2004, and 381 in 2009. Important findings show a significant reduction in both smoking parents and exposure to passive tobacco smoking (from 64% in 1994 to 45% in 2009, psmoking. These results likely reflect such a greater awareness about smoke-related risks in children, and the effectiveness of medical campaigns against cardiovascular risk factors as well.

Today Italy is the only G8 member to have no nuclear power plants in operation. In 1987 as a consequence of a referendum Italy decided to shut down its nuclear power plants and to forbid the construction of new ones. Italy relies on oil and gas imports for 80% of its energy needs. The Italian parliament has recently passed a bill for a renaissance of nuclear power. The bill gives 6 months to the government to set the rules and conditions for the come-back of nuclear energy. (A.C.)

Country policy profile - Italy. December 2015

International Nuclear Information System (INIS)

2015-12-01

In Italy, Renewable energy sources in are promoted through price and tax regulations mechanisms. Several kinds of feed-in and premium tariffs co-exist besides tendering schemes depending on technology and size of RES systems. Additionally regional support schemes exist for RES electricity. The thermal (heating and cooling) energy generated from renewable energies is incentivized through tax regulation and loans. A quota system is presently used for bio-fuels (transport). Under the country's NREAP, Italy has set a renewable energy target (electricity) of 26% to be achieved by 2020. The 2012 total share of renewable energy in Italy amounted to 13.5%; the target for 2020 has been defined as 17% (source: 'The State of Renewable Energies in Europe', 2013 edition)

Italy's recurrent energy dependency dilemma

International Nuclear Information System (INIS)

Ippolito, F.

1993-01-01

This paper first critically assesses the objectives of Italy's 1988 National Energy Plan which, in light of the moratorium on nuclear energy, called for moderate but steady reductions in imported energy supplies through the implementation of energy conservation programs and the development of available domestic conventional and renewable energy sources. The economics and energy analyses evidence that, in view this nation's current troubled economic situation, the Energy Plan's target for the year 2000 of a 76% dependency on foreign oil is just not good enough and not in line with stricter European environmental normatives limiting carbon dioxide emissions. It is argued that in order to effectively reduce the nation's excessively high energy costs, keep pace with other industrialized countries in a highly competitive market (Italy's energy tariffs are almost 55% greater than those of Germany and France), and to respect new European anti-pollution laws, Italy must restart its nuclear program and take advantage of the recent advances being made in passive reactor safety systems

In the Sicily Channel, (Central Mediterranean), two geodynamic processes overlap each other, the Maghrebides-Apennines accretionary prism and the Sicily Channel rift. Moreover, the northwestern sector (Banks sector) is characterised by an irregular seafloor morphology linked to the recent volcanic and tectonic activity.In order to discriminate the role exerted by both the processes in the morphostructural setting of the area we used a dataset of both high and very high resolution single-channel and multi-channel profiles, acquired in the frame of the RITMARE project respectively with CHIRP and sparker, and airgun sources, and high resolution (5 m cell) morpho-bathymetric data. The data allowed us to identify and characterise two areas where different geological features (sedimentary and volcanic) are prevailing. They present fluid escaping evidence, which often appears to be active and generating different types of morphologies (both positive and negative). In the western sector we recognised pockmarks at water depths of 195 to 317 m, with diameters from 25 to 580 m, depths from 1.3 to 15 m, and slope up to 23°. They show sub-circular shape in plan-view and reflectors with upward concavity in cross section, and are oriented along a NW-SE trend.The CHIRP and multichannel profiles highlight fluids that affect the Plio-Quaternary succession, especially in areas where the top surface of the Messinian succession is shallower. Conversely, wipe-out acoustic facies were recognised in proximity of: i) extensional faults of Mesozoic age with NW-SE trend; ii) dip/strike slip faults of Cenozoic age with NW-SE, N-S and about NNE-SSW trends, and iii) extensional neo-tectonic faults with NW-SE and NNW-SSE trends. We cannot exclude that they could feed the shallower reservoir producing a mixing between the two. In the eastern sector we recognised a cluster of volcanoes composed of seven cone-shaped structures (SCV1-7), pertaining to a wide area known as Graham Bank. A detailed

The Strategic Plan for Tourism Development in Italy

Directory of Open Access Journals (Sweden)

Silvia ANGELONI

2013-06-01

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

Assessment of hazards and risks for landscape protection planning in Sicily.

Science.gov (United States)

La Rosa, Daniele; Martinico, Francesco

2013-09-01

Landscape protection planning is a complex task that requires an integrated assessment and involves heterogeneous issues. These issues include not only the management of a considerable amount of data to describe landscape features but also the choice of appropriate tools to evaluate the hazards and risks. The landscape assessment phase can provide fundamental information for the definition of a Landscape Protection Plan, in which the selection of norms for protection or rehabilitation is strictly related to hazards, values and risks that are found. This paper describes a landscape assessment methodology conducted by using GIS, concerning landscape hazards, values and risk. Four hazard categories are introduced and assessed concerning urban sprawl and erosion: landscape transformations by new planned developments, intensification of urban sprawl patterns, loss of agriculture land and erosion. Landscape value is evaluated by using different thematic layers overlaid with GIS geoprocessing. The risk of loss of landscape value is evaluated, with reference to the potential occurrence of the previously assessed hazards. The case study is the Province of Enna (Sicily), where landscape protection is a relevant issue because of the importance of cultural and natural heritage. Results show that high value landscape features have a low risk of loss of landscape value. For this reason, landscape protection policies assume a relevant role in landscapes with low-medium values and they should be addressed to control the urban sprawl processes that are beginning in the area.

Mortality and rehospitalizations still remain high after discharge for an acute cardiologic event. In this context, hospital discharge represents a potential pitfall for heart disease patients. In the setting of care transitions, the discharge letter is the main instrument of communication between hospital and primary care. Communication, besides, is an integral part of high-quality, patient-centered interventions aimed at improving the discharge process. Inadequate information at discharge significantly affects the quality of treatment compliance and the adoption of lifestyle modifications for an effective secondary prevention. The Health Department of Sicily, in 2013, established a task force with the aim to elaborate "Regional recommendations for hospital discharge and communication with patients after admission due to a cardiologic event", inviting to participate GICR-IACPR and many other scientific societies of cardiology and primary care, as discharge letter and communication are fundamental junctions of care transitions in cardiology. These recommendations have been published as a specific decree and contain: a structured model of discharge letter, which includes all of the parameters characterizing patients at high clinical risk, high thrombotic risk and low risk according to the Consensus document ANMCO/GICR-IACPR/GISE; is thus possible to identify these patients, choosing consequently the most appropriate follow-up pathways. A particular attention has been given to the "Medication Reconciliation" and to the identification of therapeutic targets; an educational Kit, with different forms on cardiac diseases, risk factors, drugs and lifestyle; a check-list about information given to the patient and caregivers. The "Recommendations" represent, in conclusion, the practical realization of the fruitful cooperation between scientific societies and political-administrative institutions that has been realized in Sicily in the last years.

Induced abortion and contraception in Italy.

Science.gov (United States)

Spinelli, A; Grandolfo, M E

1991-09-01

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

Italy's green party: on the road to success

Italy's Green Party (Lista Verde) does not consider itself a political party but it is changing the environmental consciousness of the nation. There are new eight popular television shows covering environmental problems and a national weekly newspaper devotes a regular column to ecology. Environmental associations, including the Environmental League, have been started in the 1980s. The Greens have also succeeded in halting Italy's nuclear power programme. In a national referendum held in 1987 almost 80% of the voters agreed with the Greens' views. No fewer than 14 more popular referenda are planned throughout Italy on environmental issues. (UK)

The dialect in Italy after the union

2013-01-01

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

Rainfall thresholds for the possible occurrence of landslides in Italy

Directory of Open Access Journals (Sweden)

M. T. Brunetti

2010-03-01

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

Sampling and analyses methods for determining the stable isotopic compositions of Hg in an active volcanic system were tested and optimized at the volcanic complex of Vulcano (Aeolian Islands, Italy). Condensed gaseous fumarole Hg (fum)T, plume gaseous elemental Hg (g)0 and plume particulate Hg (p)II were obtained at fumaroles F0, F5, F11, and FA. The average total Hg emissions, based on Hg T/SO 2 in condensed fumarolic gases and plumes, range from 2.5 to 10.1 kg y - 1 , in agreement with published values [Ferrara, R., Mazzolai, B., Lanzillotta, E., Nucaro, E., Pirrone, N., 2000. Volcanoes as emission sources of atmospheric mercury in the Mediterranean Basin. Sci. Total Environ. 259(1-3), 115-121; Aiuppa, A., Bagnato, E., Witt, M.L.I., Mather, T.A., Parello, F., Pyle, D.M., Martin, R.S., 2007. Real-time simultaneous detection of volcanic Hg and SO 2 at La Fossa Crater, Vulcano (Aeolian Islands, Sicily). Geophys. Res. Lett. 34(L21307).]. Plume Hg (p)II increases with distance from the fumarole vent, at the expense of Hg (g)0 and indicates significant in-plume oxidation and condensation of fumarole Hg (fum)T. Relative to the NIST SRM 3133 Hg standard, the stable isotopic compositions of Hg are δ 202Hg (fum)T = - 0.74‰ ± 0.18 (2SD, n = 4) for condensed gaseous fumarole Hg (fum)T, δ 202Hg (g)0 = - 1.74‰ ± 0.36 (2SD, n = 1) for plume gaseous elemental Hg (g)0 at the F0 fumarole, and δ 202Hg (p)II = - 0.11‰ ± 0.18 (2SD, n = 4) for plume particulate Hg (p)II. The enrichment of Hg (p)II in the heavy isotopes and Hg (g)0 in the light isotopes relative to the total condensed fumarolic Hg (fum)T gas complements the speciation data and demonstrates a gas-particle fractionation occurring after the gas expulsion in ambient T° atmosphere. A first order Rayleigh equilibrium condensation isotope fractionation model yields a fractionation factor α cond-gas of 1.00135 ± 0.00058.

Bangladeshi immigrants in Italy: from geopolitics to micropolitics.

Knights, M

1996-01-01

"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

The agricultural heritage of Lampedusa (Pelagie Archipelago, South Italy and its key role for cultivar and wildlife conservation

Directory of Open Access Journals (Sweden)

Tommaso La Mantia

2011-04-01

Full Text Available As occurred on many other small Mediterranean islands, agricultural activity at Lampedusa (Strait of Sicily underwent a very strong decline in terms of surface area during the second half of the last century. In particular, cereal crops have ceased and horticulture is disappearing, while vineyards still occupy a reduced area but are quickly vanishing and currently survive thanks to a small number of old farmers. Here are presented the results of a research carried out by interviewing seven farmers in order to study not only the techniques and the germplasm used in local viticulture, but also the final use of grapes and an evaluation on the connection between traditional farming and agro-ecosystems plant species-richness. Vines were grown for wine, to produce fresh and sun-dried grapes, or to preserve them in alcohol. Several names of the local varieties suggest that they might have been introduced in Lampedusa from the neighbouring territories: being fishermen and farmers at the same time, local people had trade relationships with other Mediterranean areas such as Tunisia, Malta and Southern Italy. Furthermore, local farming plays a key role in plant conservation. In fact, the disappearance of agricultural systems is leading to the extinction of 43 plant species, some of them considered rare not only on the local level, but also on the regional and national one. Because of the small size of farmland and its fragmentation, local agriculture cannot be supported by the European Community. Therefore, in order to safeguard local viticulture, special systems of assistance and new managing policies - focused on rural development plans and showing which concrete actions are necessary and feasible to protect the agroecosystems - are needed.

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

Energy Technology Data Exchange (ETDEWEB)

NONE

2010-07-01

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

A dramatic increasing immigration flow was recorded in Europe during the last years. Only in Sicily 120,239 people arrived in 2014. Immigrants may carry neglected tropical diseases endemic in their origin countries. The aim of our study was to evaluate the frequency of geo-helminthiasis, and in particular of intestinal taeniasis, in a sample of migrants hosted in a large asylum seeker centre in the province of Catania. A stool sample was obtained from all the enrolled subjects and a coproparasitological examination was performed. Out of the 274 enrolled subjects (249 men; mean age 26.4 ± 6.2), 30 (11%) carried at least one helminthic infestation. Ancylostomatidae, Trichuris trichiura and Taenia species (spp) were the most common, the latter found in 6 (2.16%) subjects. T. solium carriers can represent a focus of infection for the more complex neurocysticercosis. Even if coproparasitological examination did not allow us to differentiate Taenia spp, we cannot exclude the presence of T. solium carriers among these subjects. Further studies, including coproantigen ELISA to detect Taenia spp, should be carried out in larger samples to better estimate the real burden of T. solium carriers.

The 1996 Altimeter/Synoptic Mesoscale Plancton Experiment (ALT/SYMPLEX) was specifically designed to perform in situ measurements simultaneous with the passage of TOPEX/POSEIDON (T/P) and ERS 2 over selected tracks in the central and eastern Sicily Channel. This experiment made it possible to have, for the first time, a validation of altimetry with in situ data over the Mediterranean, where weak dynamics results in a modest sea elevation, rarely exceeding 10 cm. Historical infrared and altimetric satellite data were first analyzed in order to study the variability of the circulation in the area. The comparative and integrative analysis of simultaneous satellite data and in situ measurements permitted investigation of the relation between the altimeter-derived surface topography and the three-dimensional structure of the sea. The Pearson correlation coefficients between altimeter data and dynamic heights along track resulted to be 0.72-0.89 (T/P) and 0.88 (ERS 2) when using conventional repeat track analysis. For T/P, a correlation value of 0.87 was found for time differences computed basing on a collinear analysis technique. This analysis also led to the identification of a strong barotropic component of the velocity field located near the Sicilian continental shelf, where it is responsible for approximately 60% of the signal.

Sicily is located in the heart of the Mediterranean and takes a strategic position between the western and eastern Mediterranean as well as between northern Africa and continental Europe. It is a place of a diverse and great cultural heritage that goes back many thousands of years; it had been colonised by Phoenicians, Carthaginians, Greeks and Romans in Ancient times and served as a trading post and granary - the latter particularly for the Romans. Climate change scenarios studies suggest that Mediterranean ecosystems could change into deserts as a consequence of shifting temperature and precipitation patterns unparalleled in the Holocene period (Guiot and Cramer, 2016). It is, therefore, essential to shed light on past precipitation changes to gain knowledge on the timing, dynamics and causes of these changes by making use of natural environmental archives (such as speleothems). This information is not only important for palaeoclimate data-model comparisons but can also give archaeologists a wealth of information when studying cultural transformations. Speleothems are valuable natural archives of past climatic and environmental conditions on the continents. Major strengths include their suitability for accurate U-series age determinations and their preservation of multiple quasi-independent climate proxies - that can be linked to precipitation changes. Hence, speleothems proxy time series from the Mediterranean can be regarded as an important testimony of past environmental and climate changes (including precipitation) that allow to provide answers to the aforementioned questions. Here we present first result of ongoing speleothem research on Sicily, with focuses on Pietrazzi cave (Grotta dei Pietrazzi) located west of Palermo. It developed in limestone (limestone consisting of bioclastic packstone/wackestones, fore reef coral rudstones (calcirudite) and calcarenites.) of the Calcare di Piano Battaglia Formation. Pietrazzi cave is more than 600 m in length and

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.

We investigate the mechanical interactions between tectonic faults and volcanic sources through elastic stress transfer and discuss the results of several applications to Italian active volcanoes. We first present the stress modeling results that point out a two-way coupling between Vesuvius eruptions and historical earthquakes in Southern Apennines, which allow us to provide a physical interpretation of their statistical correlation. Therefore, we explore the elastic stress interaction between historical eruptions at the Etna volcano and the largest earthquakes in Eastern Sicily and Calabria. We show that the large 1693 seismic event caused an increase of compressive stress along the rift zone, which can be associated to the lack of flank eruptions of the Etna volcano for about 70 years after the earthquake. Moreover, the largest Etna eruptions preceded by few decades the large 1693 seismic event. Our modeling results clearly suggest that all these catastrophic events are tectonically coupled. We also investigate the effect of elastic stress perturbations on the instrumental seismicity caused by magma inflation at depth both at the Etna and at the Alban Hills volcanoes. In particular, we model the seismicity pattern at the Alban Hills volcano (central Italy) during a seismic swarm occurred in 1989-90 and we interpret it in terms of Coulomb stress changes caused by magmatic processes in an extensional tectonic stress field. We verify that the earthquakes occur in areas of Coulomb stress increase and that their faulting mechanisms are consistent with the stress perturbation induced by the volcanic source. Our results suggest a link between faults and volcanic sources, which we interpret as a tectonic coupling explaining the seismicity in a large area surrounding the volcanoes.

The CN algorithm is here utilized both for the intermediate term earthquake prediction and to validate the seismotectonic model of the Italian territory. Using the results of the analysis, made through the CN algorithm and taking into account the seismotectonic model, three areas, one for Northern Italy, one for Central Italy and one for Southern Italy, are defined. Two transition areas, between the three main areas are delineated. The earthquakes which occurred in these two areas contribute to the precursor phenomena identified by the CN algorithm in each main area. (author). 26 refs, 6 figs, 2 tabs

Graphical abstract: Coastal recent sediments from the Strait of Sicily showed elevated concentrations of REE associated to high Th concentrations. The shale-normalized REE + Y patterns are characterized by MREE enrichments relative to HREE and LREE, manifested with a convexity along the patterns. Sm n /La n ratio, indicative of MREE enrichments, showed a significant correlation with the Th concentration. This positive correlation supports the origin of these elements by phosphogypsum-contaminated effluents from an industrial plant, located in the southern Sicilian coast. Research highlights: → REE + Y contents are higher in onshore than offshore sediments. → Anomaly in sediments near southwestern Sicilian coast (site 134): high REE + Y. → REE + Y patterns show Middle REE enrichments (convexity around Sm-Gd-Eu elements). → Sm n /La n, measure of MREE enrichments, is correlated with high Th concentrations. → Anomalies are associated with the input of phosphogypsum-contaminated effluents. - Abstract: Concentrations of rare earth elements (REE), Y, Th and Sc were recently determined in marine sediments collected using a box corer along two onshore-offshore transects located in the Strait of Sicily (Mediterranean Sea). The REE + Y were enriched in offshore fine-grained sediments where clay minerals are abundant, whereas the REE + Y contents were lower in onshore coarse-grained sediments with high carbonate fractions. Considering this distribution trend, the onshore sediments in front of the southwestern Sicilian coast represent an anomaly with high REE + Y concentrations (mean value 163.4 μg g -1 ) associated to high Th concentrations (mean value 7.9 μg g -1 ). Plot of shale-normalized REE + Y data of these coastal sediments showed Middle REE enrichments relative to Light REE and Heavy REE, manifested by a convexity around Sm-Gd-Eu elements. These anomalies in the fractionation patterns of the coastal sediments were attributed to phosphogypsum

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

High-resolution and Deep Crustal Imaging Across The North Sicily Continental Margin (southern Tyrrhenian Sea)

Science.gov (United States)

Agate, M.; Bertotti, G.; Catalano, R.; Pepe, F.; Sulli, A.

Three multichannel seismic reflection profiles across the North Sicily continental mar- gin have been reprocessed and interpreted. Data consist of an unpublished high pene- tration seismic profile (deep crust Italian CROP Project) and a high-resolution seismic line. These lines run in the NNE-SSW direction, from the Sicilian continental shelf to the Tyrrhenian abyssal plain (Marsili area), and are tied by a third, high penetration seismic line MS104 crossing the Sisifo High. The North Sicily continental margin represents the inner sector of the Sicilian-Maghrebian chain that is collapsed as con- sequence of extensional tectonics. The chain is formed by a tectonic wedge (12-15 km thick. It includes basinal Meso-Cenozoic carbonate units overthrusting carbonate platform rock units (Catalano et al., 2000). Presently, main culmination (e.g. Monte Solunto) and a number of tectonic depressions (e.g. Cefalù basin), filled by >1000 m thick Plio-Pleistocene sedimentary wedge, are observed along the investigated tran- sect. Seismic attributes and reflector pattern depicts a complex crustal structure. Be- tween the coast and the M. Solunto high, a transparent to diffractive band (assigned to the upper crust) is recognised above low frequency reflective layers (occurring be- tween 9 and 11 s/TWT) that dips towards the North. Their bottom can be correlated to the seismological (African?) Moho discontinuity which is (26 km deep in the Sicilian shelf (Scarascia et al., 1994). Beneath the Monte Solunto ridge, strongly deformed re- flectors occurring between 8 to 9.5 s/TWT (European lower crust?) overly the African (?) lower crust. The resulting geometry suggests underplating of the African crust respect to the European crust (?). The already deformed crustal edifice is dissected by a number of N-dipping normal faults that open extensional basins and are associ- ated with crustal thinning. The Plio-Pleistocene fill of the Cefalù basin can be subdi- vided into three subunits by

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.

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

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.

The authors report on the assessment of an anthropogenic mummy of a young man from the Capuchin Catacombs of Palermo, Sicily, tentatively dated from the mid- to late 19 th century AD. The mummy was investigated by full-body CT examination. CT images clearly showed aortic dissection classified as Stanford-A. Due to the relation of aortic dissection to inherited connective tissue diseases in young people, such as Marfan syndrome, conspicuous and pathological findings possibly indicating the presence of underlying Marfan syndrome were assessed. Several systemic features were scored that supported the presence of underlying Marfan syndrome in this mummy. These findings were: pectus carinatum and chest asymmetry, dural ectasia, protrusio acetabuli, dolichocephaly, down-slanting palpebral fissures, malar hypoplasia and (probable) reduced elbow extension. Aortic dissection, a cardinal feature of Marfan syndrome, turned out to be the diagnostic key for the paleoradiological diagnosis of this disease. The demonstrated CT findings contribute to the spectrum of cardiovascular diseases and inherited connective tissue disease in the fields of paleopathology and paleoradiology.

Del Borghi, M; Solisio, C; Ferrailo, G

1984-02-01

In Italy, environmental protection and energy conservation have become very important since the increase in oil prices. The law requires that all waste waters have a B.O.D. of 40 mg/l by 1986 so there has been an expansion of purification plants since 1976, using anaerobic digestion. The report deals with the current state of anaerobic treatment in Italy with particular reference to (1) animal wastes. In intensive holdings, anaerobic digestion leads to a decrease in pollution and an increase in biogas generation which can be used to cover the energy demand of the process. The factors which influence the builders of digestors for farms are considered. (2) Non toxic industrial wastes. These are the waste waters emanating from the meat packing, brewing, pharmaceutical and chemical industries. Particular reference is made to the distillery plants using anaerobic treatment prior to aerobic digestion. (3) Urban wastes. The advantages and the disadvantages are considered and further research and development is recommended. 20 references.

Degassing vs. eruptive styles at Mt. Etna volcano (Sicily, Italy): Volatile stocking, gas fluxing, and the shift from low-energy to highly-explosive basaltic eruptions

Science.gov (United States)

Basaltic magmas can transport and release large amounts of volatiles into the atmosphere, especially in subduction zones, where slab-derived fluids enrich the mantle wedge. Depending on magma volatile content, basaltic volcanoes thus display a wide spectrum of eruptive styles, from common Strombolian-type activity to Plinian events. Mt. Etna in Sicily, is a typical basaltic volcano where the volatile control on such a variable activity can be investigated. Based on a melt inclusion study in products from Strombolian or lava-fountain activity to Plinian eruptions, here we show that for the same initial volatile content, different eruptive styles reflect variable degassing paths throughout the composite Etnean plumbing system. The combined influence of i) crystallization, ii) deep degassing and iii) CO2 gas fluxing can explain the evolution of H2O, CO2, S and Cl in products from such a spectrum of activity. Deep crystallization produces the CO2-rich gas fluxing the upward magma portions, which will become buoyant and easily mobilized in small gas-rich batches stored within the plumbing system. When reaching gas dominated conditions (i.e., a gas/melt mass ratio of 0.3 and CO2,gas/H2Ogas molar ratio 5 ), these will erupt effusively or mildly explosively, whilst in case of the 122 BC Plinian eruption, open-system degassing conditions took place within the plumbing system, such that continuous CO2-fluxing determined gas accumulation on top of the magmatic system. The emission of such a cap in the early eruptive phase triggered the arrival of deep H2O-rich whose fast decompression and bubble nucleation lead to the highly explosive character, enhanced by abundant microlite crystallization and consequent increase of magma effective viscosity. This could explain why open system basaltic systems like Etna may experience highly explosive or even Plinian episodes during eruptions that start with effusive to mildly explosive phases. The proposed mechanism also determines a

Full Text Available Management of catches, effort and exploitation pattern are considered the most effective measures to control fishing mortality and ultimately ensure productivity and sustainability of fisheries.

In Italy, Renewable energy sources in are promoted through price and tax regulations mechanisms. Several kinds of feed-in and premium tariffs co exist besides tendering schemes depending on technology and size of RES systems. Additionally regional support schemes exist for RES electricity. The thermal (heating and cooling) energy generated from renewable energies is incentivized through tax regulation and loans. A quota system is presently used for bio-fuels (transport). In the year 2012 the major share of renewable electricity generation is accounted for by hydropower (3796 ktoe), mainly large plants. PV (1622 ktoe and wind power (1066 ktoe) provide the next largest contributions. As for renewable heating, solid biomass makes the largest contribution with 4671 ktoe ktoe, followed by geo thermal at 3228 ktoe. bio-fuels used in renewable transport amount to 1343 ktoe (source: EurObserv'ER, 2014, www.eurobserv-er.org). Under the country's NREAP, Italy has set a renewable energy target (electricity) of 26% to be achieved by 2020. The 2012 total share of renewable energy in Italy amounted to 13.5%; the target for 2020 has been defined as 17% (source: 'The State of Renewable Energies in Europe', 2013 edition)

Cold fusion research in Italy

Scaramuzzi, F.

1993-01-01

This paper summarizes cold fusion (CF) research in Italy. In Italy, many Agencies and Universities are moderately funding research in CF, and the scientists have made a few attempts to coordinate each other, organizing meetings and conferences. However, the activity has been mostly the fruit of the scientists' initiative, and never a coordinated proposal of Agencies and Universities. No position on the scientific validity of the subject has been officially taken and the funds for CF have been rather modest. The investments in Italy on CF, the figure referring to 1992 amounts to about 0.5 million dollars, not including expenses for personnel. A number of about 70 scientists, mostly working part-time, is committed all around the Country in research on CF. The lack of offical commitment and effective support by the Research Agencies and the Universities has not prevented scientists from being quite active in performing research. On the other side, it has to be acknowledged that no formal vetoes have been interposed to the free initiative of scientists in this field: on the contrary, some of the Agencies and Universities have moderately funded such an effort. The quality of the experiments in Italy has been increasingly good, and the results obtained are rather out standing in the general panorama of CF. But it is time to perform a more coordinated effort, keeping in mind that material science aspects, such as the characteristics of the materials used, play a very important role in the development of this topic. Thus, a much more intense effort is required to obtain a more substantial progress in the field. The increasingly convincing results obtained by the whole CF community, and the example of the Japanese Government and Industry, which appear to be determined to promoting CF research, have changed the panorama of CF. These are now signs that also the Italian scientific authorities could consider favouring research in this field in the near future. (J.P.N.)

Today Italy is the only G8 member to have no nuclear power plants in operation. In 1987 as a consequence of a referendum Italy decided to shut down its nuclear power plants and to forbid the construction of new ones. Italy relies on oil and gas imports for 80% of its energy needs. The Italian parliament has recently passed a bill for a renaissance of nuclear power. The bill gives 6 months to the government to set the rules and conditions for the come-back of nuclear energy. (A.C.)

The length of polar axis (P and the equatorial diameter (E of grain, P/E ratio, the length of colpi (C, diameter of perforations (DP and the number of perforations in 25 μm2 (PN, the width of muri (WM, the distance between muri (DM and their number in 25 μm2 (MN, the width of grooves (WG were measured and their variation was compared among studied taxa. Moreover multivariate statistical analysis was carried out to distinguish morphometric information from measured parameters. All pollen grains are trizonocolpate, isopolar, medium-large sized and their shape varies from prolate to perprolate. Regarding outline pollen grains are subtriangular in polar view and elliptic in equatorial view. Exine sculpturing is striate with perforations on grain surface. The arrangement of ridges appears roughly parallel but too sloped (sometimes curved compared to polar axis, or branched and oriented in different directions, or perfectly parallel or more irregular with bifurcated ridges often sinuous. The analyses showed a great variability (particularly in P. domestica cultivars related in some cases to the diversity in the morphological features of the leaves and the fruits of the investigated entities.

Full Text Available This paper focuses on the region of Enna in central Sicily. Its peculiar environmental setting is a key feature, with a central mountain surrounded by gentle, fertile lowlands. Our key question is to understand the regional route network in its historical process of “transformission”, a concept proposed by French archaeogeographers (see Chouquer, Watteaux 2013. It considers traces on the landscape at different scales, as ever-changing features influenced by both natural and human inputs. We chose a sample area of 566 sq-km in the very centre of the island and we evaluated geographical constraints on mobility. This raises new questions about the relationship between routes, settlements, and the environment.

Modeling, Analysis, and Preservation Techniques for Historic Reinforced Concrete Structures in Seismic Prone Regions Case Study: Augusta Airship Hangar, Sicily

Throughout the world there are hundreds of historic monuments and structures considered to be invaluable and irreplaceable. They are symbols of cultural identity and a means of educating people about history. Preservation of historic monuments and structures is therefore an important part of safeguarding these cultural heritage sites so that they retain their value for future generations.This report discusses a procedure for the investigation of seismic hazards in existing buildings and possible steps that can be taken to avoid damage caused by these hazards. The Augusta Airship Hangar located in Sicily, will be used as a case study however the topics addressed in this paper can be applied to other structures of historic value around the world.First state-of-the-art scanning procedures were used to create scale digital models that were imported into a structural analysis program. Within this program dynamic analyses were performed on the model based on actual ground motions taken close to the site. This data was used to determine the period and mode shapes of the structure. Then a nonlinear analysis, including a static pushover analysis, was implemented on a two-dimensional model of the structural frame. From this analysis the failure mechanisms of the structure were revealed with relation to an allowable roof displacement. The structural integrity of the structure was evaluated based on pre-defined performance goals. Finally multiple suggestions were made how the Augusta Airship Hangar might be repaired and strengthened so that this structure will not be destroyed should an earthquake occur.The results of our study show that historic structures, despite their age, can still be strong and ductile. Also there are a multitude of effective preservation and retrofit techniques that can be used to strengthen these historic structures, should an earthquake occur. Through this study, the Augusta Airship Hangar has proven to be not only a historic symbol for Sicily but

This paper describes the model implementation and presents results of a probabilistic seismic hazard assessment (PSHA) for the Mt. Etna volcanic region in Sicily, Italy, considering local volcano-tectonic earthquakes. Working in a volcanic region presents new challenges not typically faced in standard PSHA, which are broadly due to the nature of the local volcano-tectonic earthquakes, the cone shape of the volcano and the attenuation properties of seismic waves in the volcanic region. These have been accounted for through the development of a seismic source model that integrates data from different disciplines (historical and instrumental earthquake datasets, tectonic data, etc.; presented in Part 1, by Azzaro et al., 2017) and through the development and software implementation of original tools for the computation, such as a new ground-motion prediction equation and magnitude-scaling relationship specifically derived for this volcanic area, and the capability to account for the surficial topography in the hazard calculation, which influences source-to-site distances. Hazard calculations have been carried out after updating the most recent releases of two widely used PSHA software packages (CRISIS, as in Ordaz et al., 2013; the OpenQuake engine, as in Pagani et al., 2014). Results are computed for short- to mid-term exposure times (10 % probability of exceedance in 5 and 30 years, Poisson and time dependent) and spectral amplitudes of engineering interest. A preliminary exploration of the impact of site-specific response is also presented for the densely inhabited Etna's eastern flank, and the change in expected ground motion is finally commented on. These results do not account for M > 6 regional seismogenic sources which control the hazard at long return periods. However, by focusing on the impact of M risk reduction.

The island of Sicily has a long standing tradition in citrus growing. We evaluated the sustainability of orange and lemon orchards, under organic and conventional farming, using an energy, environmental and economic analysis of the whole production cycle by using a life cycle assessment approach. These orchard systems differ only in terms of a few of the inputs used and the duration of the various agricultural operations. The quantity of energy consumption in the production cycle was calculated by multiplying the quantity of inputs used by the energy conversion factors drawn from the literature. The production costs were calculated considering all internal costs, including equipment, materials, wages, and costs of working capital. The performance of the two systems (organic and conventional), was compared over a period of fifty years. The results, based on unit surface area (ha) production, prove the stronger sustainability of the organic over the conventional system, both in terms of energy consumption and environmental impact, especially for lemons. The sustainability of organic systems is mainly due to the use of environmentally friendly crop inputs (fertilizers, not use of synthetic products, etc.). In terms of production costs, the conventional management systems were more expensive, and both systems were heavily influenced by wages. In terms of kg of final product, the organic production system showed better environmental and energy performances. Copyright © 2013 Elsevier Ltd. All rights reserved.

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.

[Social cooperatives in Italy].

Villotti, P; Zaniboni, S; Fraccaroli, F

2014-06-01

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.

Influenza A and B viruses are responsible for respiratory infections, representing globally seasonal threats to human health. The 2 viral types often co-circulate and influenza B plays an important role in the spread of infection. A 6-year retrospective surveillance study was conducted between 2010 and 2016 in 2 large administrative regions of Italy, located in the north (Liguria) and in the south (Sicily) of the country, to describe the burden and epidemiology of both B/Victoria and B/Yamagata lineages in different healthcare settings. Influenza B viruses were detected in 5 of 6 seasonal outbreaks, exceeding influenza A during the season 2012-2013. Most of influenza B infections were found in children aged ≤ 14 y and significant differences were observed in the age-groups infected by the different lineages. B/Victoria strains prevailed in younger population than B/Yamagata, but also were more frequently found in the community setting. Conversely, B/Yamagata viruses were prevalent among hospitalized cases suggesting their potential role in the development of more severe disease. The relative proportions of viral lineages varied from year to year, resulting in different lineage-level mismatch for the B component of trivalent influenza vaccine. Our findings confirmed the need for continuous virological surveillance of seasonal epidemics and bring attention to the adoption of universal influenza immunization program in the childhood. The use of tetravalent vaccine formulations may be useful to improve the prevention and control of the influenza burden in general population.

The energy subsidiary of the Montedison chemicals company (Ferruzzi Group), Edison is Italy's largest private sector electricity producer. Last year production amounted to 4.7 TWh, an increase of 8.2% on 1990, and at the end of June this year, total net production of 2.4 TWh was 14.8% higher than in the first half of 1991. Edison also ranks first in the Italian league of private sector hydrocarbons producers, its Edison Gas subsidiary controlling a group that has significant exploration and development interests. These are mainly in Italy where production amounted to 333m cubic metres of natural gas and 690,000 barrels of oil in the first half of the year. The recent acquisition of Deutsche Shell's Italian fields should allow Edison to reach 2bn cubic metres of gas production by 1996. (author)

A socioeconomic profile of vulnerable land to desertification in Italy.

Science.gov (United States)

Salvati, Luca

2014-01-01

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

The number of mineral species in which a certain chemical element is species-defining (according to statistical data up to 2015) has been specified. Seventy chemical elements are species-defining for 5044 minerals. The following chemical elements lead in the composition of minerals (number of mineral species in parentheses): oxygen (4115), hydrogen (2800), silicon (1471), calcium (1167), sulfur (1056), aluminium (985), sodium (949), iron (945), copper (636), phosphorus (597), arsenic (594), and magnesium (571). The distribution of mineral species by various systems in the products of contemporary fumarole activity at two volcanoes, Tolbachik in Kamchatka, Russia, and Vulcano in Sicily, Italy, has been compared. These locations were also compared for the distribution of species-defining elements. Thus, it has been determined that in fumaroles of both volcanoes, Tl, S, Cl, F and Na are "excessive," present in minerals in elevated amounts, whereas H, Ca, Fe, and Mn are "deficient." The abundance of Cu, Se, V, Mg, Zn, As, and F in minerals at Tolbachik is higher than the global mean values of these elements in the Earth's crust, whereas the abundance is significantly lower at Vulcano. Sn, I, Br, K, Pb, Al, Fe, and Bi demonstrate the opposite behavior. Comparison of the Yadovitaya and Arsenatnaya fumaroles at the Tolbachik volcano showed that the products of the former are richer in H, Cl, Cu, S, K, O, Al, Fe, and Pb, and poorer in As, Ca, Mg, and Na as species-defining elements. In addition, V-and Mo-bearing minerals are found only at Yadovitaya, whereas minerals containing F, Ti, B, Te, and Zn are known only at Arsenatnaya.

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.

We look at the role of the financial sector in the context of the relatively backward regions of Southern Italy (the so-called Mezzogiorno). Commercial banks in the South typically have higher operating costs and charge higher interest rates than Northern banks. Econometric analysis on a large set of individual loan contracts suggests that borrowers in the South are considerably riskier than those elsewhere in Italy. It also indicates, however, that risk accounts for only half of the 200 basi...

A 52 year old man, living in the province of Trapani (Sicily), presented with right hydrocele and slight orchialgia. The patient underwent epididymectomy and resection of T. vaginalis. The "tunica" was involved by a granulomatous process, containing a parasite of genus Dirofilaria (D. repens). Dirofilaria repens is a filarial nematode. Dogs, foxes and cats are the definitive hosts and principal reservoirs of the parasite. In humans the parasite dies before reaching sexual maturity and the result is an inconspicuous granulomatous reaction in the subcutaneous tissue. S. Pampiglione et al. (Cattedra di Parassitologia Veterinaria dell'Università di Bologna-Italy) reported from 1971 more than 30 cases of human Dirofilariasis in Italy, suggesting that the parasite is able to migrate from the inoculation site to other districts (lung, eye etc.). The case is exceptional for the localization of the parasite (never reported) and can contribute to a better knowledge of the disease.

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

Geomagnetism and Aeronomy activities in Italy during IGY, 1957/58

Full Text Available In 2007 several events were organized to celebrate the fiftieth anniversary of the International Geophysical Year
(IGY, 1957-1958. The celebrations will last until 2009 and are taking place within different contexts: the International
Polar Year (IPY, the International Heliophysical Year (IHY, the electronic Geophysical Year (eGY
and the International Year of Planet Earth (IYPE.
IGY offered a very appropriate and timely occasion to undertake a series of coordinated observations of various
geophysical phenomena all over the globe. Italy took part in the broad international effort stimulated by IGY. In
fact, Italy participated in observations and studies in many of the proposed scientific areas, in particular Geomagnetism
and Aeronomy. The Istituto Nazionale di Geofisica (ING started the installation of observatories,
and updated and ensured continuous recording of geophysical observations. Geomagnetism, ionospheric
physics, seismology, and other geophysical disciplines, were advanced. Although much of the work was undertaken
in Italy, some attention was also devoted to other areas of the world, in particular Antarctica, where Italy
participated in seismological observations. This paper gives a summary of the Geomagnetism and Ionospheric
Physics activities within IGY. Furthermore, we highlight the importance of this historical event and its outcomes
for the improvement of geophysical observations and the post-IGY growth of scientific investigations in Italy.

Full Text Available The Blackmouth catshark, Galeus melastomus, Rafinesque, 1810 (Carcharhiniformes; Scyliorhinidae, is a common, although at present discarded, by- catch of the bottom trawl fisheries in the Strait of Sicily. Given its ecological interest, data gathered in experimental bottom trawl surveys were analysed in order to describe its distribution and main biological traits. The Blackmouth catshark was sampled almost exclusively on the upper slope (200-800, showing the highest frequency of occurrence (69-100%, biomass (BI; 10-85 kg*km-2 and density (DI; 54-506 N*km-2 indexes in the deeper (501-800m grounds.

A total of 25 lichen thalli of Parmelia conspersa (Ehrh), collected at Vulcano island and at Mt. Etna, during a one-year biogeochemical survey, were analyzed for Pb, br, Al, Sc,[sup 206]Pb/[sup 207]Pb, and [sup 208]Pb/[sup 206]Pb ratios. Lead isotope ratios were also measured on aerosol samples from urban areas and industrial sites of Sicily. The observed [sup 206]Pb/[sup 207]Pb range for urban and industrial aerosols matches the anthropogenic signature. Lichens instead, are closer to the compositional field of [sup 206]Pb rich geogenic sources. This natural input is more evident at Vulcano island than at Mt. Etna, where the anthropogenic activities are considerably more effective. On the basis of lead isotope data, Pb/Br ratios and calculated lead enrichment factors, a natural lead pollution from volcanoes is suggested. Volcanic lead contribution ranges from 10 to 30% at Mt. Etna to 10--80% at Vulcano island.

We present the results of AMS radiocarbon dating of human bones recovered in 'Grotta Cappuccini', a prehistoric cave in Galatone, Lecce (Southern Italy). The AMS analysis has confirmed the archaeological dating of the cave to the period between the end of the Copper Age and the early Bronze Age, and has given a fundamental contribution to the chronological definition of an important cultural aspect of the prehistory of Southern Italy

The role of native flower visitors in pollinating Opuntia ficus-indica (L.) Mill., naturalized in Sicily

Science.gov (United States)

Lo Verde, Gabriella; La Mantia, Tommaso

2011-09-01

The role of insects in pollination and consequently in fruit set and quality was assessed in two commercial orchards of the cactus pear, Opuntia ficus-indica (L.) Mill., in Agrigento Province, Sicily. In 1997, insects visiting flowers were sampled during May-June (the first bloom) and July (the second bloom, induced by the "scozzolatura" practise). More than 50 insect species belonging to 10 orders were collected in May-June, while only five species of Hymenoptera Apoidea were collected in July. The quality of fruits arising from the second bloom showed that Hymenoptera alone were able to guarantee effective pollination. To verify the role of insects in pollination in 1996 (during only the second bloom), and in 1997 and 2009 (during both blooms), 60 single flowers were marked during each bloom; 30 of them covered with paper sleeves (which prevented natural pollination), while the others were not covered. After withering, fruits produced by marked flowers were analyzed in laboratory: in all years and blooms, the total number of seeds, the number of developed seeds, and the weight and the percentage of pulp were significantly lower for covered flowers than for non-covered flowers. The results are consistent with the hypothesis that native insects effectively carry out the pollination of cactus pear flowers.

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

Antonio Magliulo

2018-04-01

Full Text Available Nowadays the Austrian School enjoys high reputation in Italy: books by Mises, Hayek and other Austrian economists are constantly republished and reviewed with great interest, both inside and outside academic circles. The situation was very different decades ago, when just a few Italian economists devoted attention to the Austrian School. This work studies the reception of Austrian Economics in Italy, from the beginning to our days, so as to bring out, by way of comparison, relevant features of Italian economic culture. We will try to offer just an overview of the entire story, in an attempt to provide useful elements for a deeper analysis of further topics and periods.

Underground storage of natural gas in Italy

International Nuclear Information System (INIS)

Henking, E.

1992-01-01

After first relating the importance of natural gas storage to the viability of Italian industrial activities, this paper discusses the geo-physical nature of different types of underground cavities which can be used for natural gas storage. These include depleted petroleum and natural gas reservoirs, aquifers and abandoned mines. Attention is given to the geologic characteristics and physical characteristics such as porosity, permeability and pressure that determine the suitability of any given storage area, and to the techniques used to resolve problems relative to partially depleted reservoirs, e.g., the presence of oil, water and salt. A review is made of Italy's main storage facilities. This review identifies the various types of storage techniques, major equipment, operating and maintenance practices. A look is then given at Italy's plans for the development of new facilities to meet rising demand expected to reach 80 billion cubic meters/year by the turn of the century. The operating activities of the two leading participants, SNAM and AGIP, in Italy's natural gas industry are highlighted. Specific problems which contribute to the high operating costs of natural gas storage are identified and a review is made of national normatives governing gas storage. The report comes complete with a glossary of the relative terminology and units of measure

Chapter 44: history of neurology in Italy.

Science.gov (United States)

Bentivoglio, Marina; Mazzarello, Paolo

2010-01-01

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

Economic Sustainability of Italian Greenhouse Cherry Tomato

Directory of Open Access Journals (Sweden)

Riccardo Testa

2014-11-01

Full Text Available Greenhouse tomato cultivation plays an important role in Sicily, being the primary production area in Italy, due to its favorable pedo-climatic conditions that permit extra-seasonal productions. In Sicily, more than half of greenhouse tomato production is derived from the Province of Ragusa on the southeastern coast, where especially cherry tomato typologies are cultivated. Over the last decade, the Ragusa Province has registered a decrease both in terms of greenhouse tomato area and harvested production due to several structural problems that would require restructuring of the tomato supply chain. Thus, since recognition of real costs and profitability of tomato growing is a vital issue, both from the perspective of the farm, as well as from that of the entrepreneur, the aim of this paper was to analyze the economic sustainability of Sicilian greenhouse cherry tomato cultivated in the Ragusa Province. In particular, an economic analysis on 30 representative farms was conducted in order to estimate production costs and profits of greenhouse cherry tomato. According to our results, the lack of commercial organization, which characterizes the small farms we surveyed, determines low contractual power for farmers and, consequently, low profitability.

Integration of historical, archaeoseismic and paleoseismological data for the reconstruction of the early seismic history in Messina Strait (south Italy: the 1st and 4th centuries AD earthquakes

Directory of Open Access Journals (Sweden)

Maria Serafina Barbano

2014-03-01

Full Text Available Historical accounts, archaeoseismic and paleoseismological evidence allowed us to reappraise two earthquakes affecting northeastern Sicily and southern Calabria in the 1st (probably between 14 and 37 and 4th (likely between 361 and 363 centuries AD, to obtain a better reconstruction of their effects and to reconsider their sources.The 1st century event damaged the area from Oppido (Calabria to Tindari (Sicily, roughly that of the February 6, 1783 Calabria earthquake. The similitude of these earthquakes is further stressed by the fact that they generated tsunamis, as recorded by historical data and by the tsunami deposits found at Capo Peloro, the oldest dated 0-125 AD, the youngest linked to the 1783 event. These earthquakes could be related to the same Calabria seismic source: the Scilla fault. Northeastern Sicily and southern Calabria were also damaged by one or more earthquakes in the 4th century AD and several towns were rebuilt/restored at that time. The hit area roughly coincides with that of the Messina 1908 earthquake suggesting similar seismic sources for the events. However, because close in time, historical descriptions of the 4th century Sicilian earthquake were mixed with those of the 365 Crete earthquake that generated a basin-wide tsunami most likely reaching also the Sicilian coasts. Reevaluating location, size, damage area and tsunamigenic potential of these two earthquakes of the 1st and 4th centuries AD is relevant for reassessing the seismogenic and tsunamigenic potential of the faults around the Messina Strait and the seismic hazard of the affected areas.

A Bayesian kriging model for estimating residential exposure to air pollution of children living in a high-risk area in Italy

Ana M. Vicedo-Cabrera

2013-11-01

Full Text Available A core challenge in epidemiological analysis of the impact of exposure to air pollution on health is assessment of the individual exposure for subjects at risk. Geographical information systems (GIS-based pollution mapping, such as kriging, has become one of the main tools for evaluating individual exposure to ambient pollutants. We applied universal Bayesian kriging to estimate the residential exposure to gaseous air pollutants for children living in a high-risk area (Milazzo- Valle del Mela in Sicily, Italy. Ad hoc air quality monitoring campaigns were carried out: 12 weekly measurements for sulphur dioxide (SO2 and nitrogen dioxide (NO2 were obtained from 21 passive dosimeters located at each school yard of the study area from November 2007 to April 2008. Universal Bayesian kriging was performed to predict individual exposure levels at each residential address for all 6- to 12-years-old children attending primary school at various locations in the study area. Land use, altitude, distance to main roads and population density were included as covariates in the models. A large geographical heterogeneity in air quality was recorded suggesting complex exposure patterns. We obtained a predicted mean level of 25.78 (±10.61 μg/m3 of NO2 and 4.10 (±2.71 μg/m3 of SO2 at 1,682 children’s residential addresses, with a normalised root mean squared error of 28% and 25%, respectively. We conclude that universal Bayesian kriging approach is a useful tool for the assessment of realistic exposure estimates with regard to ambient pollutants at home addresses. Its prediction uncertainty is highly informative and can be used for both designing subsequent campaigns and for improved modelling of epidemiological associations.

Invasioni biologiche. Il caso drammatico delle palme e di due specie di insetti, il Punteruolo rosso delle palme (Rynchophorus ferrugineus, Coleotteri e il castnide delle palme (Paysandisia archon, Lepidotteri in Italia

Full Text Available The biological invasions represent today a serious ecological problem, and is one of the main threats to biodiversity, in Italy as in the rest of the world. In the last century several species of palm trees have been introduced in gardens, parks and lanes of great part of Italy, where climate allows their life and growth. Among the others Phoenix canariensis, P. dactylifera, Washingtonia robusta, W. filifera, Jubaea spectabilis and Trachycarpus fortunei. All of these species are exotic, as the only indigenous palm in Italy is the dwarf fan palm (Chamaerops humilis, which occurs along the tirrenian coast from Sicily to Liguria, in Sardinia and most of the smaller islands. Palm trees have become by now part of the Italian landscape, as do pine tree in Rome or cypress in Tuscany. Recently, two different species of exotic insects where recorded for the first time in Italy: the south American moth Paysandisia archon and the chinese beetle Rhynchophorus ferrugineus. Both of them lay their eggs on palm trees, and their larvae feed into the stem and kill the palms. Both arrived in Italy and in other Mediterranean countries as larvae or eggs hidden into the plants imported from the native regions. These insects are rapidly spreading through Italy, following palm plantations, and destroying palms from north to south, with a huge economic damage. Furthermore, they are locally changing probably for ever the Italian landscape. More recently, there is evidence of infestation on dwarf fan palm by both the moth and the beetle. This could cause a local extinction of the palm.

Full Text Available Normal 0 14 false false false MicrosoftInternetExplorer4 Normal 0 14 false false false IT X-NONE X-NONE MicrosoftInternetExplorer4 Herein, we present and discuss the result of 148 measurements of soil CO2 flux performed for the first time in Linosa island (Sicily Channel, Italy, a Plio-Pleistocene volcanic complex no longer active but still of interest owing to its location within a seismically active portion of the Sicily Channel rift system. The main purpose of this survey was to assess the occurrence of CO2 soil degassing, and compare flux estimations from this island with data of soil degassing from worldwide active volcanic as well as non-volcanic areas. To this aim soil CO2 fluxes were measured over a surface of about 4.2 km2 covering ~80% of the island. The soil CO2 degassing was observed to be mainly concentrated in the eastern part of the island likely due to volcano-tectonic lineaments, the presence of which is in good agreement with the known predominant regional faults system. Then, the collected data were interpreted using sequential Gaussian simulation that allowed estimating the total CO2 emissions of the island. Results show low levels of CO2 emissions from the soil of the island (~55 ton d-1 compared with CO2 emissions of currently active volcanic areas, such as Miyakejima (Japan and Vulcano (Italy. Results from this study suggest that soil degassing in Linosa is mainly fed by superficial organic activity with a moderate contribution of a deep CO2 likely driven by NW-SE trending active tectonic structures in the eastern part of the island.

Energy and environment in Italy

2001-01-01

Based upon the more meaningful changing recorded within the Italian energy sector in the year 2000, the Studies Department of ENEA (the Italian National board for new technologies, energy and environment) prepared the 'Rapporto Energia e Ambiente 2000', which provides a picture of the country energy and energy-related activities concerning the environment. In this paper, it is only provided a summary of the whole work. The complete report can be downloaded from the ENEA main page (www.enea.it). Italy gross domestic product (Gdp) grew by almost 3% in the year 2000, mostly sustained by an increase in the industrial production and services, as well. At the same time the total energy consumption rose to almost 185 Mtoe (+1% over 1999). Because Gdp grew more than the energy consumption, the energy intensity decreases in the year 2000. Almost 82% of the Italian energy needs (mainly oil and gas, even if electricity imports are increasing) depend upon imports. This heavy burden makes Italy particularly sensitive to both the oil price fluctuations and the euro/dollar exchange rate. Transportation absorbs a large and growing share of the energy consumption while showing quite an impact on the environment. From the supply side, renewable energy sources appear very promising because they allow the use of local resources, promote local development and may create new jobs, in area of the country with less favourable economic conditions. First among the European countries, a market mechanism to increase the use of renewable by establishing that a share of the whole electricity production (currently set at 2%) has to come from renewable has been introduced. However among the OECD countries, Italy records the lowest rate of R/D investments to GDP. This rate should more than double if the new opportunities coming from the development of innovative energy technologies have to be fully exploited [it

Italy: An Open Air Museum

Pizzorusso, Ann

2016-04-01

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.

Reproductive features of the deep-water rose shrimp, Parapenaeus longirostris (Crustacea: Penaeidae, in the Strait of Sicily

Directory of Open Access Journals (Sweden)

M.L. BIANCHINI

2010-02-01

Full Text Available The deep‑water rose shrimp, Parapenaeus longirostris (Lucas, 1846, is one of the most valuable and heavily exploited demersal species of the Mediterranean bottom trawl fisheries. The basic life traits of this shrimp, in particular its reproductive aspects, are regularly monitored during experimental trawl surveys carried out in the Mediterranean Sea. Gonadic condition and maturity status for estimating the size at onset of sexual maturity are commonly assessed in females, using macroscopic color scales, histologically validated only in a few geographical areas. In this study, histological analyses were performed on rose shrimps collected from a trawl survey carried out in the Strait of Sicily, in order to support the empirical 4‑stage macroscopic scale locally employed. Ovaries from females of different sizes, ranging between 16 mm and 40 mm carapace length, were collected and used for microscopic examination of their structure, for oocytes counts and for oocyte diameter frequency distributions; oocytes diameter was measured by imaging analysis. The collected data were also used to estimate other basic vital parameters of the rose shrimp population. The histological observations show a broad correspondence between ovarian development and macroscopic features; therefore, the classifications derived by the empirical scale remain suitable for estimating the maturity parameters.

In A Queer Place in Time: Fictions of Belonging in Italy 1890-2010

Science.gov (United States)

Atwood, Christopher Burke

In a Queer Place in Time: Fictions of Belonging in Italy 1890-2010 maps the "elsewheres"---spatial, temporal and intertextual--- that authorize same-sex desire in modern Italy. Tracing a genealogy that spans from nineteenth century travel writing about Italy to contemporary Italian novels, I argue that texts exported from the Northern Europe and the U.S. function as vital site of affiliation and vexing points of discrepancy for Italy's queers. Pier Vittorio Tondelli's Camere separate (1989), for instance, cites the British novelist Christopher Isherwood as proof that -- somewhere else -- silence did not yoke homosexuality. Rather than defining sexuality as a constant set of desires, I demonstrate it to be a retroactive fiction. It is the fleeting affinity that the reading of inherited texts can evoke. In examining the reception of transnational gay narratives in the national context of Italy, this dissertation argues that the concept of "Western" homosexuality is internally riven. Ultimately, In a Queer Place in Time illuminates how local histories -- including affective differences like shame, estrangement and backwardness -- continue to haunt gay culture's global fictions. !

Molecular characterization of Giardia duodenalis cysts in the Oreto River (Sicily, Southern Italy

Maria Antonella Di Benedetto

2010-03-01

Full Text Available

Background: The presence of Giardia was investigated along the Oreto river between January 2008 and May 2009 with the aim of understanding the source of contamination by molecular typing of cysts.

Methods: A total of 38 water samples (10 collected from the river mouth, 24 from the whole Oreto basin and 4 sewage samples from the Monreale treatment plant were processed. In addition, 22 faecal samples of livestock living close to the Oreto area, were analyzed. The presence of Giardia was determined by immunofluorescence assay and their genetic characterization was achieved by a nested PCR assay targeting the triosephosphate isomerase gene.

Results: All water samples from the river mouth were positive for Giardia, even if the concentration of cysts fluctuated considerably among sampling occasions. Our investigation showed that the Vadduneddu and Altofonte torrents, two influents of the river, were the principal sources of contamination. Moreover, the genotypes of Vadduneddu torrent were the same as those detected in human wastewater taken from the activated sludge plant of Monreale city. Assemblages A and B were found in water samples with a predominance of Assemblage A, subtype AII. Assemblage E was only found in a single calf isolate.

Conclusions: The data show that the high cyst counts regularly detected in the Oreto river are due to contamination with wastewater of human origin. This finding is relevant for public health, particularly because river water is used for agricultural purposes.

Desiato, F.; Fioravanti, G.; Fraschetti, P.; Perconti, W.; Toreti, A.

2011-05-01

In Italy, meteorological data necessary and useful for climate studies are collected, processed and archived by a wide range of national and regional institutions. As a result, the density of the stations, the length and frequency of the observations, the quality control procedures and the database structure vary from one dataset to another. In order to maximize the use of those data for climate knowledge and climate change assessments, a computerized system for the collection, quality control, calculation, regular update and rapid dissemination of climate indicators was developed. The products publicly available through a dedicated web site are described, as well as an example of climate trends estimates over Italy, based on the application of statistical models on climate indicators from quality-checked and homogenised time series.

Full Text Available Italy played special attention to the province of Vlora during World War I, because of its great strategic importance in the Adriatic Sea. Italy had deployed in October 1914 in Sazan and had occupied Vlore since December 1914. But for the Albanian people, the liberation of Vlora was a key moment for its survival. It was the victorious War of Vlora in 1920, following the decisions of the Congress of Lushnja which reconfirmed Albania's independence and which put Albania in the course of a normal independent country. The important role of the war in direct confrontation with the Italian political and military forces of the time, are intended to be reflected in this article based on historical arguments and new perspective of our days.

Full Text Available The economic crisis in Italy after 2008 fully revealed the complexity of the socio-economic model of the country, which in our time is formed not only at national level but also at European and global levels. All these factors should also be taken into account in the analysis of Russian-Italian relations. Italy has traditionally been considered one of the main partners / allies of Russia in Europe / the West, which emphasizes the active economic ties.Socio-economic diffi culties in Italy, creating both challenges and opportunities for the world, Europe and Russia. One of the major challenges for the global economy is the impact of the crisis in Italy for the EU, as one of the world's economic centers.The challenge for the EU crisis in Italy can be the stability of the EU, the challenge for Russia could be the eff ect of reducing the role of the traditional economic and political partner of the EU. Regarding the new features are: the global level – the transformation of one of the major economies of the West and building relationships with updated economic leader of the Mediterranean on a new basis, the regional level - the further development of one of the other German centre’s of the EU, which could serve as a new "stimulus" for the further integration of the Union , national - improve the socio-economic standards of living of citizens in Italy, as well as creating additional opportunities for the development of mutually benefi cial cooperation with other countries, particularly with Russia.

Power programmes review: Nuclear power in Italy

1959-07-15

Several concrete measures have been initiated in Italy for the generation of nuclear power on a substantial scale. Two plants are already under construction and work will start soon on a third. Plans have also been announced for more stations. If the work already initiated is completed on schedule the installed capacity of nuclear power in Italy is likely to exceed 500 mw (electric) in the course of the next four years. This will constitute a sizeable proportion of the total electrical capacity in the country. After the Italian National Committee for Nuclear Research (Comitato Nazionale per le Ricerche Nucleari) was reorganized late in 1956, it prepared what can be described as a nuclear five-year plan for Italy. The plan, designed to cover the period 1957-1962, includes detailed schemes for a comprehensive development of the peaceful uses of nuclear energy, including a programme for the generation of power. The Comitato Nazionale per le Ricerche Nucleari (CNRN) promotes and co-ordinates the various activities in the field, and within the framework of its general programme certain industrial groups in Italy have formulated specific projects for nuclear power. At a Geneva conference (1958) it was disclosed that several companies were planning to build nuclear power stations in Italy. (1) SELNI (Societa Elettronucleare Italiana), pertaining to the Edison-Volta group, which plans to build a pressurized water reactor. (2) So.R.I.N. (Societa Ricerche Impianti Nucleari), a company founded by the Fiat and Montecatini groups, which is constructing a research centre, with a swimming pool reactor, and various laboratories for chemistry, physics and metallurgy. This centre will also be used for the training of specialized personnel, in view of the company's programme which envisages two 150 mw (e) plants: one operating with enriched uranium, the other with natural uranium. Such a programme will become effective only when the cost of power produced by these plants may actually

to investigate hypothesised relationships between diet and cancer by assessing diet as a whole, in the Italian cohort EPIC. multicentric prospective study. 47,749 volunteers were recruited between 1993 and 1998 in the centres of Varese and Turin (Northern Italy), Florence (Central Italy), Naples and Ragusa (Southern Italy). Information on diet and lifestyle were collected through validated questionnaires. Anthropometric measurements were taken and biological samples collected using standardised protocols. follow-up was carried out by accessing regional cancer and mortality registries, hospital discharge records, and by telephone inquiries (only for Naples). After a median follow-up of 11 years, 879 incident cases of breast cancer, 421 cases of colorectal cancer, and 152 deaths were identified. Multivariate Cox regression models were used to estimate risks in relation to dietary characteristics. the "Olive oil & Salad" dietary pattern, characterised by high consumption of raw vegetables and olive oil, was associated with a lower risk of overall mortality in the elderly. Adherence to a Mediterranean diet rich in vegetables and fruit was associated with reduced risk of colon cancer. Consumption of high-glycemic carbohydrates was associated with higher incidence of breast cancer and colorectal cancer. Reduced risk of colon cancer was also found in regular consumers of yoghurt. the accuracy and comprehensiveness of EPIC-Italy data made it possible to investigate both individual dietary components and dietary habits as a whole, to thereby provide Italians with dietary and lifestyle advice that will help them to remain healthy.

The sea-air exchange of mercury (Hg) in the marine boundary layer of the Augusta basin (southern Italy): concentrations and evasion flux.

The first attempt to systematically investigate the atmospheric mercury (Hg) in the MBL of the Augusta basin (SE Sicily, Italy) has been undertaken. In the past the basin was the receptor for Hg from an intense industrial activity which contaminated the bottom sediments of the Bay, making this area a potential source of pollution for the surrounding Mediterranean. Three oceanographic cruises have been thus performed in the basin during the winter and summer 2011/2012, where we estimated averaged Hgatm concentrations of about 1.5±0.4 (range 0.9-3.1) and 2.1±0.98 (range 1.1-3.1) ng m(-3) for the two seasons, respectively. These data are somewhat higher than the background Hg atm value measured over the land (range 1.1±0.3 ng m(-3)) at downtown Augusta, while are similar to those detected in other polluted regions elsewhere. Hg evasion fluxes estimated at the sea/air interface over the Bay range from 3.6±0.3 (unpolluted site) to 72±0.1 (polluted site of the basin) ng m(-2) h(-1). By extending these measurements to the entire area of the Augusta basin (~23.5 km(2)), we calculated a total sea-air Hg evasion flux of about 9.7±0.1 g d(-1) (~0.004 tyr(-1)), accounting for ~0.0002% of the global Hg oceanic evasion (2000 tyr(-1)). The new proposed data set offers a unique and original study on the potential outflow of Hg from the sea-air interface at the basin, and it represents an important step for a better comprehension of the processes occurring in the marine biogeochemical cycle of this element.

An Overview of Italy's Energy Mix

International Nuclear Information System (INIS)

Cammi, Corrado; Assanelli, Mattia

2012-01-01

In Italy, the issue of energy supply is always of great interest because this country depends on foreign imports for 83% of its primary energy needs. This is due to the limited availability of domestic mineral resources, combined with a strong dependence of the electricity production on fossil fuels. The present situation should be viewed in the light of the decision to freeze the nuclear program following the referendum of 1987. Italy's energy strategy subsequently turned back to the thermoelectric sector, which was updated, during the latter part of the 1990's, with several modern and efficient plants, mainly based on a combined cycle structure and fed by natural gas. In addition, the Italian government has started to fund renewables, in compliance with the European regulations, and these forms of energy have experienced a significant increase, especially in recent years. The current energy-mix makes the Italian economy more exposed to the global geopolitical instabilities of the oil- and gas-producing countries, compared to northern European countries. Moreover, with the shift of economic activities towards the service sector, the demand of electric energy is increasing and its costs, weighted also by renewable incentives, are becoming more and more significant for Italian users and the economy in general. These issues, coupled with the constraints set by the European 20-20-20 plan, in particular in terms of polluting gas emissions and energy savings, led the Berlusconi government (2008-2011) to resort to a new nuclear program. This relied on the construction of 4 EPR power plants (at least) in order to cover 25% of Italy's entire electricity needs. But the program was stopped by another referendum in June 2011, whose result was strongly influenced by the Fukushima tragedy. However, a new national energy strategy has not yet been defined. This paper analyses the present energy mix, with particular attention to the electricity production system, in order to

SOCIO-ECONOMIC CONSEQUENCES OF IMMIGRATION IN ITALY

Directory of Open Access Journals (Sweden)

Elena J. Tsareva

2014-01-01

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

The Second World Cholera Pandemic (1826-1849) in the Kingdom of the Two Sicilies with Special Reference to the Towns of San Prisco and Forio d'Ischia.

The second world cholera pandemic in Europe (1829-1849) was significant because of its geographic extent and the enormous numbers of people who fell ill or died. It was also singularly important because it demonstrated the profound levels of ignorance in both Europe and North America concerning the cause, modes of transmission, and treatment of cholera. This paper discusses the pandemic in the Kingdom of the Two Sicilies in great detail. Even though medical and public health authorities in this kingdom had several years to prepare for cholera's eventual arrival in 1836-1837, their elaborate preventive and therapeutic measures proved no more successful than elsewhere. Despite their efforts, it was estimated that there were 32,145 cases of cholera in the city of Naples by July 1837. Some 19,470 people were estimated to have died among the city's then 357,283 population. This amounted to a cholera-specific mortality rate of 54.5/1000 population. Sicily was also severely affected by the epidemic. It was estimated that 69,000 people died of cholera in Sicily, 24,000 of them in the city of Palermo. Two rural towns in the kingdom, San Prisco and Forio d'Ischia, were selected for in-depth epidemiologic study. The former had a population of 3700 in 1836-1837, while the latter had a population of 5500. The economic basis of both towns was agriculture. However, because Forio is located on an island, fishing and sea transport were then also important industries. Cholera appeared in San Prisco in July 1837 and quickly swept through the population. By August, the epidemic was essentially over. It is estimated that some 109 people died from cholera in San Prisco for a disease-specific mortality rate of 29.5/1000 population. The age range of those who died from cholera was 1 to 90 years. The majority of deaths (60.6 %) were among women. The first cases of cholera appeared in Forio d'Ischia in June 1837. The epidemic then peaked in July. It is estimated that approximately 316

Is marriage loosing its centrality in Italy?

Directory of Open Access Journals (Sweden)

2004-09-01

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

A systematic review of the quality of studies on dementia prevalence in Italy

Gianluca Bruti

2016-10-01

Full Text Available Abstract Background Dementia, including Alzheimer’s disease (AD, is one of the most burdensome medical conditions. In order to better understand the epidemiology of dementia in Italy, we conducted a systematic search of studies published between 1980 and April 2014 investigating the prevalence of dementia and AD in Italy and then evaluated the quality of the selected studies. Methods A systematic search was performed using PubMed/Medline and Embase to identify Italian population-based studies on the prevalence of dementia among people aged ≥60 years. The quality of the studies was scored according to Alzheimer’s Disease International (ADI criteria. Results Sixteen articles on the prevalence of dementia and AD in Italy were eligible and 75 % of them were published before the year 2000. Only one study was a national survey, whereas most of the studies were locally based (Northern Italy and Tuscany. Overall, the 16 studies were attributed a mean ADI quality score of 7.6 (median 7.75. Conclusions Available studies on the prevalence of dementia and AD in Italy are generally old, of weak quality, and do not include all regions of Italy. The important limitations of the few eligible studies included in our analysis, mostly related to their heterogeneous design, make our systematic review difficult to interpret from an epidemiologic point of view. Full implementation of a Dementia National Plan is highly needed to better understand the epidemiology of the disease and monitor dementia patients.

Nuclear Renaissance in Italy: Maintaining Momentum

International Nuclear Information System (INIS)

Iaccarino, F.

2010-01-01

Following the adoption of Law No.99 of July 209, Italy is on threshold of returning to nuclear power, even though there are many more challenges yet to overcome. It should be recalled that Law No. 99/2009 includes enabling provisions empowering the government to issue one or more implementing decrees providing rules for the sitting of new nuclear power plants, the licensing process for the construction, operation and dismantling of those plants, as well as rules for interim storage and the final disposal of nuclear waste. On 15 February 2010, upon the proposal of the Ministry of economic development, the Italian council of ministers issued legislative decree No. 31/2010 implementing the enabling provisions. This paper will analyse the strengths and weaknesses of the implementing decree in order to assess if it is able to provide Italy with a sound national nuclear legislative framework which is an essential precondition to the Italian nuclear resurgence.

When probabilistic seismic hazard climbs volcanoes: the Mt. Etna case, Italy - Part 1: Model components for sources parameterization

Science.gov (United States)

Azzaro, Raffaele; Barberi, Graziella; D'Amico, Salvatore; Pace, Bruno; Peruzza, Laura; Tuvè, Tiziana

2017-11-01

The volcanic region of Mt. Etna (Sicily, Italy) represents a perfect lab for testing innovative approaches to seismic hazard assessment. This is largely due to the long record of historical and recent observations of seismic and tectonic phenomena, the high quality of various geophysical monitoring and particularly the rapid geodynamics clearly demonstrate some seismotectonic processes. We present here the model components and the procedures adopted for defining seismic sources to be used in a new generation of probabilistic seismic hazard assessment (PSHA), the first results and maps of which are presented in a companion paper, Peruzza et al. (2017). The sources include, with increasing complexity, seismic zones, individual faults and gridded point sources that are obtained by integrating geological field data with long and short earthquake datasets (the historical macroseismic catalogue, which covers about 3 centuries, and a high-quality instrumental location database for the last decades). The analysis of the frequency-magnitude distribution identifies two main fault systems within the volcanic complex featuring different seismic rates that are controlled essentially by volcano-tectonic processes. We discuss the variability of the mean occurrence times of major earthquakes along the main Etnean faults by using an historical approach and a purely geologic method. We derive a magnitude-size scaling relationship specifically for this volcanic area, which has been implemented into a recently developed software tool - FiSH (Pace et al., 2016) - that we use to calculate the characteristic magnitudes and the related mean recurrence times expected for each fault. Results suggest that for the Mt. Etna area, the traditional assumptions of uniform and Poissonian seismicity can be relaxed; a time-dependent fault-based modeling, joined with a 3-D imaging of volcano-tectonic sources depicted by the recent instrumental seismicity, can therefore be implemented in PSHA maps

The climatic change induced by the global warming is expected to modify the agricultural activity and consequently the other social and economical sectors. In this context, an efficient management of the water resources is considered very important for Italy and in particular for Southern areas characterized by a typical Mediterranean climate in order to improve the economical and environmental sustainability of the agricultural activity. Climate warming could have a substantial impact on some agronomical practices as the choice of the crops to be included in the rotations, the sowing time and the irrigation scheduling. For a particular zone, the impact of climatic change on agricultural activity will depend also on the continuum "soil-plant-climate" and this continuum has to be included in the analysis for forecasting purposes. The Project CLIMESCO is structured in four workpackages (WP): (1) Identification of homogeneous areas, (2) Climatic change, (3) Optimization of water resources and (4) Scenarios analysis. In this study we applied a statistical downscaling method, Canonical Correlation Analysis after Principal Component Analysis filtering, to two sub-regions of agricultural interest in Sicily and Apulia (respectively, Delia basin and Capitanata). We adopt, as large scale predictors, the sea level pressure from the the EMULATE project dataset and the 1000 hPa temperature obtained from the NCEP reanalyses, while the predictands are monthly time series of maximum and minimum temperature and precipitation. As the crop growth models need daily datasets, a stochastic weather generator (the LARS-WG model) has been applied for this purpose. LARS-WG needs a preliminary calibration with daily time series of meteorological fields, that are available in the framework of CLIMESCO project. Then, the statistical relationships have been applied to two climate change scenarios (SRES A2 and B2), provided by three different GCM's: the Hadley Centre Coupled Model version 3 (Had

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

Goethe's Italian Journey and the geological landscape

Science.gov (United States)

Coratza, Paola; Panizza, Mario

2015-04-01

Over 220 years ago Johann Wolfgang von Goethe undertook a nearly two-years long and fascinating journey to Italy, a destination dreamed for a long time by the great German writer. During his journey from Alps to Sicily Goethe reflects on landscape, geology, morphology of "Il Bel Paese", sometimes providing detailed descriptions and acute observations concerning the great and enduring laws by which the earth and all within it are governed. He was an observer, with the eye of the geologist and landscape painter, as he himself stated, and therefore he had a 360 degree focus on all parts of the territory. From the Brenner Pass to Sicily, Goethe reflects on landscape, contrasting morphologies, the genesis of territories, providing detailed descriptions useful for reconstructing the conditions of the territory and crops of the late 18th century. His diary is a description of the impressions he received from the country and its people, mingled with reflections upon art, science and literature. Goethe studied mineralogical and geological phenomena and drew up notes on the life of the people, the climate and the plants. On various scientific occasions and, in particular, within the framework of the Italian Association "Geologia & Turismo", of the Working Group "Geomorphosites" of the International Association of Geomorphologists and the International Year of Planet Earth, the opportunity to re-examine Goethe's travels in Italy from a geological viewpoint was recognised. In the present paper an attempt was made to reproduce the geotourism itinerary ante litteram of the writer to Italy, one of the most important tourist destination worldwide, thanks to its rich cultural and natural heritage and the outstanding aesthetic qualities of the complex natural landscape. This project was essentially conceived with a twofold purpose. First of all, an attempt was made to reproduce the journey of a great writer, as an example of description of landscape perceived and described as

Sedimentary evolution of the Mesozoic continental redbeds using geochemical and mineralogical tools: the case of Upper Triassic to Lowermost Jurassic Monte di Gioiosa mudrocks (Sicily, southern Italy)

The continental redbeds from the Internal Domains of the central-western Mediterranean Chains have an important role in the palaeogeographic and palaeotectonic reconstructions of the Alpine circum-Mediterranean orogen evolution since these redbeds mark the Triassic-Jurassic rift-valley stage of Tethyan rifting. The composition and the sedimentary evolution of the Middle Triassic to Lowermost Jurassic continental redbeds of the San Marco d'Alunzio Unit (Peloritani Mountains, Southern Italy), based on mineralogical and chemical analyses, suggests that the studied mudrock sediments share common features with continental redbeds that constitute the Internal Domains of the Alpine Mediterranean Chains. Phyllosilicates are the main components in the mudrocks. The 10 Å-minerals (illite and micas), the I-S mixed layers, and kaolinite are the most abundant phyllosilicates. The amount of illitic layers in I-S mixed layers coupled with the illite crystallinity values (IC) are typical of high degree of diagenesis, corresponding to a lithostatic/tectonic loading of about 4-5 km. The mineralogical assemblage coupled with the A-CN-K plot suggest post-depositional K-enrichments. Palaeoweathering proxies (PIA and CIW) record intense weathering at the source area. Further, the studied sediments are affected by reworking and recycling processes and, as consequence, it is likely these proxies monitor cumulative effect of weathering. The climate in the early Jurassic favoured recycling and weathering occurred under hot, episodically humid climate with a prolonged dry season. The source-area is the low-grade Paleozoic metasedimentary basement. Mafic supply is minor but not negligible as suggested by provenance proxies.

Environmental radioactivity networks in Italy, 1994-1997

1999-01-01

This report contains the environmental radioactivity data collected in Italy from 1994 to 1997 by the National Environmental Radioactivity Networks of Italy. The National Environmental Protection Agency (ANPA) is law-fully responsible for publishing the environmental and dietary contamination data, provided by the organisations participating to the National Environmental Radioactivity Networks. The complete list of the participants is reported at the end of the present document. The National Environmental Radioactivity Networks of Italy are aimed at survey of the pattern of environmental and dietary contamination in order to assess the radiation doses which the Italian population may receive. The sampling networks have been designed on regional basis, to provide information on the average extent of environmental and dietary contamination. The sampling programmes are planned to obtain representative samples able to reveal the average situation both in time and space. To guarantee that the laboratories of the organisations participating to the National Environmental Radioactivity Networks, perform measurements with a certain degree of accuracy and maintain the quality of their systems, the National Environmental Protection Agency organises yearly an intercalibration programme of the analytical methods used for measuring radioactivity in food and environmental samples. The calibration programme is performed with the collaboration of the National Institute of Ionising Radiation Metrology (ENEA). Routine tests with transfer standards are used for accurate calibration, so that the results can be traceable to a common reference point [it

Full Text Available Abstract From December 1986 to May 1988 the diet of the fox was studied by analysis of 539 droppings of which 349 gathered in a woodland (Province of Palermo throughout a year (1987 and 190 in different localities of the Sicily. Invertebrates (77%, mostly Arthropods, were the staple food, followed by fruits (38%, Mammals (31% and Birds (12%. Mammals were especially represented by small species (21% and occasionally by Lagomorphs (4%; they mainly occurred in winter and spring. Fruits and Invertebrates were eaten in a good number throughout the year with peaks of frequency in autumn and in summer. The feeding habits of the fox in Sicily are typical of a generalist species. Riassunto Da dicembre 1986 a maggio 1988, la dieta della Volpe è stata studiata mediante l'analisi di 539 feci, di cui 349 raccolte nel bosco di Ficuzza (provincia di Palermo, dove sono state evidenziate le variazioni stagionali delle categorie alimentari rilevate, e 190 in diverse località della Sicilia. I dati raccolti sono stati espressi come frequenza percentuale delle presenze. Le principali componenti della dieta sono gli Invertebrati (77% rappresentati soprattutto da Artropodi, i frutti (38%, i Mammiferi (31% e gli Uccelli (12%. I Mammiferi sono costituiti prevalentemente da specie di piccole dimensioni (21% e occasionalmente da Lagomorfi (4%, e sono predati soprattutto in inverno e primavera. I frutti e gli Invertebrati sono abbondantemente consumati per l'intero arco dell'anno e mostrano picchi di presenza in autunno e in estate. In Sicilia, le abitudini alimentari della Volpe sono tipiche di un predatore generalista.

Cover crops for managing weeds, soil chemical fertility and nutritional status of organically grown orange orchard in Sicily

Rosario Paolo Mauro

2015-06-01

Full Text Available Cover crops can offer significant advantages in the agronomic management of citrus orchards in Mediterranean environments. Therefore, a three-year research was conducted in eastern Sicily aimed at studying the effects of four cover crop sequences (Sinapis arvensis-Trigonella foenum-graecum-T. foenum-graecum; Medicago scutellata-Avena sativa-Lolium perenne; Vicia faba minor-A. sativa-A. sativa; A. sativa-V. faba. minor-L. perenne on weeds, major soil chemical properties and nutritional status of an organically grown orange orchard. The results highlighted that, among the studied cover crop sequences, Vicia faba-Avena-Avena was the most beneficial for weeds control within the orchard (92%, of cover crop cover, and 586 and 89 g DW m–2 of cover crop aboveground biomass and weeds aboveground biomass, respectively. Overall, the chemical fertility of the soil was positively influenced. In particular, it was observed an increase of the content of total nitrogen and available phosphorus in the soil by both Sinapis-Trigonella-Trigonella (0.75 g kg–1 and 59.0 mg kg–1, respectively and Vicia faba-Avena-Avena (0.70 g kg–1 and 56.0 mg kg–1, respectively cover crop sequences. Medicago-Avena-Lolium sequence seemed to be the most useful to ensure a better nutritional status of the orange orchard.

A unique fossil record from neptunian sills: the world's most extreme example of stratigraphic condensation (Jurassic, western Sicily)

Science.gov (United States)

Wendt, Jobst

2017-06-01

Neptunian sills at Rocca Busambra, a fragment of the Trapanese/Saccense Domain in western Sicily, host the most abundant ammonite and gastropod fauna which has ever been recorded from the Jurassic of the western Tethys. The fauna is dominated by parautochthonous organisms which were swept into the sills by gentle transport. Ammonites are characterized by perfect preservation and small size, a feature which is due to the predominance of microconchs but also of stunting. The most complete sill is 0.7 m thick and could be separated into 17 levels which range in age from the early Toarcian into the late Kimmeridgian, thus representing the most extreme case of palaeontologically and depositionally documented stratigraphic condensation in Earth history. The unique feature of the Rocca Busambra sills is due to the interaction of three processes: extreme stratigraphic condensation on the sea floor, weak tectonic fracturing of the host rock and repeated reopening on top of already existing sills. Contrasting percentages of gastropods in individual levels reflect sea-level oscillations which correspond to long known low- and highstands during the Jurassic of the western Tethys. Comparisons with other ammonite-bearing sill faunas reveal several similarities, but represent only short-timed phases of tectonic pulses and deposition.

Geological record of tsunami inundations in Pantano Morghella (south-eastern Sicily both from near and far-field sources

Directory of Open Access Journals (Sweden)

F. Gerardi

2012-04-01

Full Text Available Analysis of tsunami deposits from the Pantano Morghella area provided geological evidence for two inundations occurred along the south-eastern Ionian coast of Sicily. Pantano Morghella is a large pond characterised by a fine-grained sedimentation indicating a low-energy depositional environment. Two anomalous yellow sandy layers found at different depths indicate the occurrence of high-energy marine inundations. We studied sedimentological and paleontological features of the anomalous deposits as well as their spatial distribution observing the following properties: different facies with respect to the local stratigraphic sequence; erosive bases, rip-up clasts and broken elements testifying violent deposition mechanisms; macro and micro fauna of marine environment; relatively constant thickness throughout most of the depositional zone with thinning at the distal end; large sand sheets that extend inland. These observations, jointly with their infrequency in the sedimentary record and the age indicating a fast deposition, provided strong evidence for tsunami inundations. Correlations between anomalous layers and historical tsunamis are supported by radiocarbon and OSL dating results. The younger deposit is likely due to the 1908 near-source tsunami, whereas the flooding of the oldest event is most likely associated with a far and large source, the Crete 365 AD earthquake.

2006-04-01

As part of an epidemiological surveillance of infectious bronchitis virus (IBV) in Spain, four Spanish field isolates showed high S1 spike sequence similarities with an IBV sequence from the GenBank database named Italy 02. Given that little was known about this new emergent IBV strain we have characterized the four isolates by sequencing the entire S1 part of the spike protein gene and have compared them with many reference IBV serotypes. In addition, cross-virus neutralization assays were conducted with the main IBV serotypes present in Europe. The four Spanish field strains and the Italy 02 S1 sequence from the NCBI database were established as a new genotype that showed maximum amino acid identities with the 4/91 serotype (81.7% to 83.7%), the D274 group that included D207, D274 and D3896 strains (79.8% to 81.7%), and the B1648 serotype (79.3% to 80%). Furthermore, on the basis of these results, it was demonstrated that the Italy 02 genotype had been circulating in Spain since as early as 1997. Based on the average ratio of synonymous:non-synonymous (dS/dN) amino acid substitutions within Italy 02 sequences, no positive selection pressures were related with changes observed in the S1 gene. Moreover, phylogenetic analysis of the S1 gene suggested that the Italy 02 genotype has undergone a recombination event. Virus neutralization assays demonstrated that little antigenic relatedness (less than 35%) exists between Italy 02 and some of the reference IBV serotypes, and indicated that Italy 02 is likely to be a new serotype.

Cases of bed bug (Cimex lectularius infestations in Northwest Italy

Directory of Open Access Journals (Sweden)

Federica Giorda

2013-12-01

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

New evidence for the serpentinization of the Palaeozoic basement of southeastern Sicily from joint 3-D seismic velocity and attenuation tomography

Science.gov (United States)

Giampiccolo, E.; Brancato, A.; Manuella, F. C.; Carbone, S.; Gresta, S.; Scribano, V.

2017-12-01

In this study, we derived the first 3-D P-wave seismic attenuation images (QP) as well as new 3-D VP and VP/VS models for the crust in southeastern Sicily. We used a large data set of local seismic events occurring in the time span 1994-2013. The results of this tomographic study have important implications on the seismic behaviour of the region. Based on velocity and attenuation images, we identified distinct volumes characterized by different fluid content, which correlate well with seismicity distribution. Moreover, the obtained velocity and attenuation tomographies help us to provide a more complete picture of the crustal structure of the area. High VP, high QP and high VP/VS values have been obtained in the crustal basement, below a depth of 8 km, and may be interpreted as due to the presence of serpentinized peridotites. Accordingly, the new model for the degree of serpentinization, retrieved from VP values, shows that the basement has an average serpentinization value of 96 ± 3 vol.% at 8 km, decreasing to 44 ± 5 vol.% at about 18-20 km.

The study area includes the Municipalities of Gela, Niscemi and Butera located in the South of Sicily, Italy. In 1990 it was declared Area at High Risk of Environmental Crisis. In 2000 part of it was designated as Gela Reclamation Site of National Interest, RSNI. The site includes a private industrial area, public and marine areas, for a total of 51 km(2). Gela populationin 2008 was 77,145 (54,774 in 1961). Sea level:46 m. Total area: 276 km(2). Grid reference: 37 degrees 4' 0" N, 14 degrees 15' 0" E. Niscemi and Butera are located border to Gela. Populations are respectively 26,541 and 5,063. Sea level respectively: 332 m and 402 m. Close to the city of Gela, the industrial area, operating since 1962, includes chemical production plants, a power station and an oil refinery plant, one of the larger in Europe, refining 5 millions tons of crude per year. From the beginning the workforces decreased from 7,000 to the current 3,000 units. Over the years, these industrial activities have been a major source of environmental pollution. Extremely high levels of toxic, persistent and bio-accumulating chemical pollutants have been documented. Many relevant environmental and health data are available. Prior to the studies described in the present publication, their use in order to identify environmental pressures on health has been limited. Nevertheless, since several years different epidemiological studies have provided evidence of the occurrence of health outcomes significantly higher than in neighbouring areas and compared to regional data. In 2007 a Multidisciplinary Working Group has been established, to analyze the existing data on pollution-exposure-effect and to complete current knowledge on the cycle of pollutants, from migration in the environment to health impact. The present publication is a collection of contribution of this group of experts, supported by the following projects: Evaluation of environmental health impact and estimation of economic costs at of

2017-11-01

Psychoanalysis experienced a remarkable boom in 1960s Italy. One of the areas where psychoanalytic theory disseminated was the world of marketing and the sociology of consumption. Based on the case of the sociologist Francesco Alberoni, we can examine the impact of the theories of Melanie Klein for understanding the behavior of consumers. Similarly, Alberoni's work shows the concerns and uncertainties on the social modernization of Italy, and also raises questions on the specificities of the growing importance of psychoanalysis in Italy in the 1960s.

ENEA initiatives in Southern Italy: Progress report, analysis, prospects

Santandrea, E.

1991-01-01

In the past, technological development in Italy was concentrated in the country's heavily industrialized northern regions. The motive for this choice was the conception that to be successful in a highly competitive market, research investment had necessarily to favour those developed areas with an already proven capacity for guaranteed fast and high returns. Unfortunately this policy has created a technologically and economically depressed area, known as Mezzogiorno, in southern Italy. Within the framework of new national energy and economic policies calling for balanced economic and technological development, ENEA (Italian Commission for New Technologies, Energy and the Environment) has been entrusted with the planning and managing of research, commercialization and technology transfer programs designed to stimulate high-technology industrial activity in Italy's southern regions so as to allow them to become more competitive in the upcoming European free trade market. Small business concerns shall be favoured in this new development scheme which shall respect the existing local social-economic framework. Emphasis shall be placed on privileging such elements as quality, flexibility and versatility, as opposed to lost cost mass production. Priority is to be given to the development of renewable energy sources, energy conservation techniques and environmentally compatible technologies

Catechesis in Italy between the Two Vatican Councils – 1870–1962

Directory of Open Access Journals (Sweden)

Carl‑Mario Sultana

2017-11-01

Full Text Available The article endeavours to give a bird’s eye view of catechesis in Italy as from 1870 to the threshold of Vatican Council II – 1962. The point of departure is a study of the use of the Catechism as the handbook for catechesis. The study will then move on study the efforts of individuals – from priests to Pope Pius X – who sought to positively influence catechesis through their ministry and how different Congresses and Conventions helped in trying to formulate a more coherent catechesis throughout Italy. Finally, the paper will end by a study of the Active Method which was to be the unifying factor for catechesis in Italy prior to Vatican Council II.

Crustal structure of the Ionian basin and eastern Sicily margin : results from a wide angle seismic survey and implication for the crustal nature and origin of the basin, and the recent tear fault location

In the Ionian Sea (Central Mediterranean) the slow convergence between Africa and Eurasia results in the formation of a narrow subduction zone. The nature of the crust and lithosphere of the subducting plate remain debated and could represent the last remnants of the Neo-Tethys ocean. The rifting mechanism that produced the Ionian basin are also still under discussion with the Malta escarpment representing a possible remnant of this opening. At present, this subduction is still retreating to the south-east (motion occurring since the last 35 Ma) but is confined to the narrow Ionian Basin. In order to accommodate slab roll-back, a major lateral slab tear fault is required. This fault is thought to propagate along the eastern Sicily margin but its precise location remains controversial. This study focuses on the deep crustal structure of the Eastern-Sicily margin and the Malta Escarpment by presenting two wide-angle velocity profiles crossing these structures roughly orthogonally. The data used for the forward velocity modeling were acquired onboard the R/V Meteor during the DIONYSUS cruise in 2014. The results image an oceanic crust within the Ionian basin as well as the deep structure of the Malta Escarpment which presents characteristics of a transform margin. A deep and asymmetrical sedimentary basin is imaged south of the Messina strait and seems to have opened in between the Calabrian and Peloritan continental terranes. The interpretation of the velocity models suggests that the tear fault is located east of the Malta Escarpment, along the Alfeo fault system.

District heating in Italy: Extent of use

International Nuclear Information System (INIS)

Sacchi, E.

1992-01-01

The Author surveys the trend that has been established over the last two decades in the use of district heating in Italy. Comparison with the European situation reveals that Italy is lagging behind. The reason for this the Author states is the Italian public's aversion to unknown risks involved in the utilization of innovative technologies associated with cogeneration/district heating (current preference is given to autonomous methane fuelled building space heating systems), and the current opinion of some misinformed public administrations that cogeneration/district heating plants are too costly. Citing the successful campaign by the natural gas industry to promote the public acceptance of methane as a safe, readily available and competitively priced energy source, he suggests that similar efforts be made to have the public also accept cogeneration (with methane fired gas turbines)/district heating as being safe and environmentally, as well as, economically beneficial

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.

Metals in molluscs and algae: A north-south Tyrrhenian Sea baseline

International Nuclear Information System (INIS)

Conti, Marcelo Enrique; Finoia, Maria Grazia

2010-01-01

We develop a 800 km long relative baseline of metal pollution for the Tyrrhenian Sea, from the north of Naples to south of Sicily (Italy), based on spatio-temporal (1997-2004) concentrations of trace metals in marine organisms and on the bioaccumulative properties of those organisms. The study concerns sites in the gulf of Gaeta-Formia, near Naples, and three islands north, west, and south of Sicily: Ustica, Favignana and Linosa. The five metals are: cadmium, chromium, copper, lead, and zinc; the species include: Monodonta turbinata (n = 161), Patella caerulea (n = 244) and the algae Padina pavonica (n = 84). We use Johnson's (1949) probabilistic method to determine the type of distribution that accounts for our data. It is a system of frequency curves that represents the transformation of the standard normal curves. We find an N-S pollution gradient in molluscs considered: the lowest metal pollution occurs around the Sicilian islands. Our method can accurately characterize marine pollution by contributing to: policy-making, coastal resources management, the assessments of environmental damages from marine accidents and other events. The method here presented is a useful tool for pollution comparisons purposes among ecosystems (i.e., risk monitoring) and it is an ideal starting point for its application on a global scale.

Crude oil is one of the most important natural assets for humankind, yet it is a major environmental pollutant, notably in marine environments. One of the largest crude oil polluted areas in the word is the semi-enclosed Mediterranean Sea, in which the metabolic potential of indigenous microbial populations towards the large-scale chronic pollution is yet to be defined, particularly in anaerobic and micro-aerophilic sites. Here, we provide an insight into the microbial metabolism in sediments from three chronically polluted marine sites along the coastline of Italy: the Priolo oil terminal/refinery site (near Siracuse, Sicily), harbour of Messina (Sicily) and shipwreck of MT Haven (near Genoa). Using shotgun metaproteomics and community metabolomics approaches, the presence of 651 microbial proteins and 4776 metabolite mass features have been detected in these three environments, revealing a high metabolic heterogeneity between the investigated sites. The proteomes displayed the prevalence of anaerobic metabolisms that were not directly related with petroleum biodegradation, indicating that in the absence of oxygen, biodegradation is significantly suppressed. This suppression was also suggested by examining the metabolome patterns. The proteome analysis further highlighted the metabolic coupling between methylotrophs and sulphate reducers in oxygen-depleted petroleum-polluted sediments. © 2015 The Authors.

The HXR79 hard X-Ray experiment was flown August 26th 1979 from the Milo Base (Sicily, Italy) and a 27-hour flight was achieved. The scientific payload consisted of two Multiwire Spectroscopic Proportional Counters with 900 cm 2 sensitive geometric area each, in the hard X-Ray range (16 to 180 keV). A single drift scan was performed on the Crab Nebula region after the balloon reached the flotation point (2.9 mbar). The observation gave a maximum counting rate of about 25 counts/s superimposed on a background of about 75 counts/s. The Crab power-law spectrum was observed, and these data provide evidence for a line emission enhancement around 70 keV. (author)

Werner, M. J.; Zechar, J. D.; Marzocchi, W.; Wiemer, S.

2010-12-01

On 1 August 2009, the global Collaboratory for the Study of Earthquake Predictability (CSEP) launched a prospective and comparative earthquake predictability experiment in Italy. The goal of the CSEP-Italy experiment is to test earthquake occurrence hypotheses that have been formalized as probabilistic earthquake forecasts over temporal scales that range from days to years. In the first round of forecast submissions, members of the CSEP-Italy Working Group presented eighteen five-year and ten-year earthquake forecasts to the European CSEP Testing Center at ETH Zurich. We considered the twelve time-independent earthquake forecasts among this set and evaluated them with respect to past seismicity data from two Italian earthquake catalogs. Here, we present the results of tests that measure the consistency of the forecasts with the past observations. Besides being an evaluation of the submitted time-independent forecasts, this exercise provided insight into a number of important issues in predictability experiments with regard to the specification of the forecasts, the performance of the tests, and the trade-off between the robustness of results and experiment duration.

In recent years, an increasing number of surveys have definitively confirmed the seasonal presence of fin whales (Balaenoptera physalus) in highly productive regions of the Mediterranean Sea. Despite this, very little is yet known about the routes that the species seasonally follows within the Mediterranean basin and, particularly, in the Ionian area. The present study assesses for the first time fin whale acoustic presence offshore Eastern Sicily (Ionian Sea), throughout the processing of about 10 months of continuous acoustic monitoring. The recording of fin whale vocalizations was made possible by the cabled deep-sea multidisciplinary observatory, “NEMO-SN1”, deployed 25 km off the Catania harbor at a depth of about 2,100 meters. NEMO-SN1 is an operational node of the European Multidisciplinary Seafloor and water-column Observatory (EMSO) Research Infrastructure. The observatory was equipped with a low-frequency hydrophone (bandwidth: 0.05 Hz–1 kHz, sampling rate: 2 kHz) which continuously acquired data from July 2012 to May 2013. About 7,200 hours of acoustic data were analyzed by means of spectrogram display. Calls with the typical structure and patterns associated to the Mediterranean fin whale population were identified and monitored in the area for the first time. Furthermore, a background noise analysis within the fin whale communication frequency band (17.9–22.5 Hz) was conducted to investigate possible detection-masking effects. The study confirms the hypothesis that fin whales are present in the Ionian Sea throughout all seasons, with peaks in call detection rate during spring and summer months. The analysis also demonstrates that calls were more frequently detected in low background noise conditions. Further analysis will be performed to understand whether observed levels of noise limit the acoustic detection of the fin whales vocalizations, or whether the animals vocalize less in the presence of high background noise.

Remarkable differences among European countries have been found in stroke rehabilitation models, owing to the fact that stroke rehabilitation services are embedded in health care systems. Comprehensive data on service utilization by stroke survivors in Italy are lacking, but would be instrumental in improving efficiency and effectiveness of post-acute stroke care, and consequently, in containing costs and improving outcomes. The purpose of the present study was to survey the Italian regional legislations in order to examine the provision of rehabilitation services for stroke survivors in Italy. This is a cross-sectional, observational study. Post-stroke intra- and extra-hospital rehabilitation. All decrees and resolutions as to post-acute stroke rehabilitation were collected from each Italian region. All decrees and resolutions were examined by the means of a check list including quantitative and qualitative characteristics, selected in accordance with national official recommendations. Each completed check list was then sent to each regional reference person, who filled in the section on the implementation of the indications and compliance. The study was carried out from November 2009 to September 2010. The documents were collected from 19 out of the 20 Italian regions. The results of the study indicate that there are many, remarkable regional variations in health policies concerning post-stroke care. Instruments for evaluation and criteria for allocating stroke patients to proper rehabilitation setting vary across regions, but data on the potential impact of these variations on clinical outcomes are still lacking. The study highlights the issue that, in Italy, delivery of post-stroke rehabilitation services is not uniform nation-wide and varies substantially across regions. The lack of a comprehensive post-acute stroke strategy is a major obstacle to service availability. The study results advocate the need for a consistent and comprehensive strategic planning of

In view of the economic importance of durum wheat in Italy and in the Mediterranean and Near East Region much effort was devoted to its genetic improvement. Lodging susceptibility and straw weakness, particularly under high fertilizer level, were the main reasons of substantially lower yields compared to bread wheat. An experimental mutagenesis programme was started in Italy in 1956 by F. D'Amato and G.T. Scarascia. It included both fundamental genetic studies and applied mutation breeding. Remarkable results were obtained at the 'Laboratorio Applicazioni in Agricoltura', Casaccia Nuclear Research Center, Roma, Italy, in radiobiology, radiogenetics, cytology and cytogenetics, genetics and breeding. Selection among some 1,000 induced mutants and hybridization led to 11 registered mutant varieties, six by the direct use of selected mutants and the remaining from cross-breeding. The economic benefits derived from the developed mutant cultivars are substantial. Mutant varieties have a great impact on durum wheat production, both in Italy and other countries like Bulgaria or Austria where Italian mutants have been used successfully in cross-breeding.

Rosaria Costa

2017-01-01

Full Text Available The quality parameter of alkyl esters of fatty acids was checked in a variety of Italian olive oil samples. In particular, 34 samples of extra virgin olive oils (EVOOs from South Italy (Sicilian orchards, produced in the years 2014-2015, have been subjected to the analytical protocol dictated by the European Union for the determination of alkyl esters, as an indicator of oil’s quality. All the samples analyzed resulted to be well below the limit set by EU Directive. Besides recently produced EVOOs, a set of very aged oils, produced in the years 1996–2000, were analyzed as well. The main finding was that alkyl esters increased in correspondence with deterioration processes.

Large Human Outbreak of West Nile Virus Infection in North-Eastern Italy in 2012

Full Text Available Human cases of West Nile virus (WNV disease have been reported in Italy since 2008. So far, most cases have been identified in north-eastern Italy, where, in 2012, the largest outbreak of WNV infection ever recorded in Italy occurred. Most cases of the 2012 outbreak were identified in the Veneto region, where a special surveillance plan for West Nile fever was in place. In this outbreak, 25 cases of West Nile neuroinvasive disease and 17 cases of fever were confirmed. In addition, 14 WNV RNA-positive blood donors were identified by screening of blood and organ donations and two cases of asymptomatic infection were diagnosed by active surveillance of subjects at risk of WNV exposure. Two cases of death due to WNND were reported. Molecular testing demonstrated the presence of WNV lineage 1 in all WNV RNA-positive patients and, in 15 cases, infection by the novel Livenza strain was ascertained. Surveillance in other Italian regions notified one case of neuroinvasive disease in the south of Italy and two cases in Sardinia. Integrated surveillance for WNV infection remains a public health priority in Italy and vector control activities have been strengthened in areas of WNV circulation.

We examine the possibility the Organisation for Economic Co-operation and Development (OECD) bed count for Italy may be an underestimation of the actual beds available. We compared bedded services for mental disorders in two regions in Italy and Canada respectively. We found out that if we consider acute psychiatric beds only, the district of Ferrara has 30 beds (8.5 per 100,000) and the Middlesex and Elgin Counties have 89 beds (16.3 beds for 100,000). However, if we include the rehabilitation beds (that are located within a hospital setting in Ontario and in a residential community setting in Ferrara), we find that the district of Ferrara has 95 beds (27.0 per 100,000) and the Middlesex and Elgin Counties have 176 beds (32.3 per 100,000). As a result, the 10/100,000 beds rate for Italy reported by the OECD is an underestimate compared to figures reported for most other countries, as the beds included are hospital beds only.

Full Text Available Herniation pits (HPs of the femoral neck were first described in a radiological publication in 1982 as round to oval radiolucencies in the proximal superior quadrant of the femoral neck on anteroposterior radiographs of adults. In following early clinical publications, HPs were generally recognized as an incidental finding. In contrast, in current clinical literature they are mentioned in the context of femoroacetabular impingement (FAI of the hip joint, which is known to cause osteoarthritis (OA. The significance of HPs in chronic skeletal disorders such as OA is still unclear, but they are discussed as a possible radiological indicator for FAI in a large part of clinical studies.In this paleoradiological study we examined a sample of mummies from the Capuchin Catacombs of Palermo, Sicily, by a mobile computed tomography (CT scanner. Evaluation of the CT examinations revealed HPs in six out of 16 (37.5% adult male mummies.The first aim of this study was to compare the characteristics of HPs shown in our mummy collection to the findings described in clinical literature. Thereby CT evaluation revealed that their osseous imaging characteristics are in accordance, consisting of round to oval subcortical lesions at the anterior femoral neck, clearly demarcated by a sclerotic margin.The second aim was to introduce HPs to the paleoradiological and paleopathological methodology as an entity that underwent a renaissance from an incidental finding to a possible radiological indicator of FAI in the clinical situation. As FAI plays an important role in the development of OA of the hip, which is a very common finding in human skeletal remains, HPs should always be considered in paleoradiological evaluation of hip joint diseases.

The impact of landslides are an issue for many urban cities and their cultural heritage, especially where both natural factors and human actions are join. Indeed in these cases, both the geological-geomorphological area predisposition and the continuous human actions increase the possibility occurrence of a landslide. In order to study these landslides and their natural hazard, a multi-disciplinary approach is necessary. Agrigento (37°19'18''N; 13°35'22''E), founded around 580 b.C. along the Sicilian southern coast, is an example of a possible impacts of landslides on cultural heritage. This work discusses the geological, geomorphological and hydrological data results, performed in order to study and the monitoring the landslide on the north side of the Agrigento hill (335 m a.s.l.), on which is localized the antique cathedral (sixteenth century) and the old city. The hill geology is a typical regressive Plio-Pleistocene succession and their lithology are clays (Monte Narbone formation) , calcarenites , sands and silts of the Agrigento formation. The landslide phenomena, current since 1315, involves a calcarenitic pack (Pleistocene), weakly cemented, highly porous, fractured and fissured (E-W). This phenomena from 1924, at different times, have produced various types of instability such as: falls, flows and complex movements. From 7 March 2005 have been reactivated fractures of the calcarenitic pack, already highlighted by studies in 1966. These fractures have triggered slope movements damaging the cathedral and the various historic buildings. In order to reduce the risk and thus safeguard the monuments and the activity in this area, carried out the several studies. Since 2005, the landslide is the subject both geological-geomorphological studies and a continuous monitoring, which have used different techniques of different disciplines: interferometric analysis, interpretation of aerial and satellite imagery, geophysical investigations, stratigraphic survey, etc. The results of this studies carried out the landslide kinematics and the lithology involved, in this way it was possible to suggest targeted intervention. Keywords: rotational landslide, rockfall, hazard, architectural heritage.

Full Text Available Accurate detection of time gravity changes attributable to the dynamics of volcanoes requires high-precision gravity measurements. With the aim of improving the quality of data from the Mount Etna gravity network, we used both absolute and relative gravimeters in a hybrid method. In this report, some of the techniques for gravity surveys are reviewed, and the results related to each method are compared. We show how the total uncertainty estimated for the gravity measurements performed with this combined use of absolute and relative gravimeters is roughly comparable to that calculated when the measurements are acquired using only relative gravimeters (the traditional method. However, the data highlight how the hybrid approach improves the measurement capabilities for surveying the Mount Etna volcanic area. This approach enhances the accuracy of the data, and then of the four-dimensional surveying, which minimizes ambiguities inherent in the gravity measurements. As a case study, we refer to two gravity datasets acquired in 2005 and 2010 from the western part of the Etna volcano, which included five absolute and 13 relative stations of the Etna gravity network.

This study assessed coastal erosion vulnerability along a 90-km sector, which included both erosional and accretionary beaches, and different levels of human occupation. Two aerial photogrammetric flights were used to reconstruct coastal evolution between 1977 and 1999. During this period, extensive accretion was recorded updrift of human structures at harbors and ports, e.g., Scoglitti (105.6 m), Donnalucata (52.8 m), and Pozzallo (94.6 m). Conversely, erosion was recorded in downdrift areas, with maximum values at Modica Stream mouth (63.8 m) and Point Castellazzo (35.2 m). Assessments were subsequently divided into four categories ranging from “high erosion” to “accretion.” Several sources were examined to assess human activities and land use. The latter was mapped and divided into four categories, ranging from “very high” to “no capital” land use. Subsequently, coastal erosion vulnerability was assessed by combining land use categories with recorded coastline behavior. Results showed “very high” to “high” vulnerability along 5.8% and 16.6%, respectively, of the littoral, while 20.9% and 56.7%, respectively, was found to exhibit “medium” and “low/very low” vulnerability. A very good agreement between predicted coastal vulnerability and coastal trend had been observed over recent years. Furthermore, several human structures and activities are located within the “imminent collapse zone (ICZ)” which reached maximum values of 17.5 m at Modica Stream and 13.5 m at Point Braccetto.

Seismotectonic activity and slope instability are a permanent threat in the archaeological site of Abakainon and in the nearby village of Tripi in NE Sicily. In recent times, signs of an ancient earthquake have been identified in the necropolis of Abakainon which dating was ascertained to the first century AD earthquake. The site is located on a slope of Peloritani Mts. along the Tindari Fault Line and contains evidence for earthquake-induced landslide, including fallen columns and blocks, horizontal shift and counter slope tilting of the tomb basements. In this paper, we used an integrated geomorphological and geophysical analysis to constrain the landslide. The research was directed to the acquisition of deep geological data for the reconstruction of slope process and the thickness of mobilized materials. The applied geophysical techniques included seismic refraction tomography and electrical resistivity tomography. The surveys were performed to delineate the sliding surface and to assess approximately the thickness of mobilized materials. The geophysical and geomorphologic data confirmed the presence of different overlapped landslides in the studied area. Moreover, a numerical simulation of the slope under seismic loads supports the hypothesis of a mobilization of the landslide mass in case of strong earthquakes (PGA > 0.3 g). However, numerical results highlight that the main cause of destruction for the Abakainon necropolis is the amplification of the seismic waves, occasionally accompanied by surficial sliding.

The promotion of energy efficiency in Italy

De Paoli, L.; Bongiolatti, L.

2006-01-01

In 2004 Italy introduced an obligation for electricity and gas distribution companies to reach specific objectives regarding the improvement of energy efficiency in final energy consumption. The scope of the provision is to promote investments in energy efficiency in order to meet the greenhouse gases reduction target set by the Kyoto protocol. The adoption of binding targets of energy efficiency will also lead to the development of an energy services market, modifying the traditional relation between energy dealers and final consumers, thus leading to a more efficient use of the available resources. Similar mechanisms have already been applied in other European countries (as France and United Kingdom) and will be likely introduced in other countries with the implementation of European Directive on energy end-use efficiency and energy services. This paper describes and analyzes both the measures adopted in Italy and the results obtained after the first year of operation of the mechanism. The paper is divided in six different sections. In the first part we highlight the main problems related to the development of system based on tradable white certificates. In the second part we provide a brief description of the Italian regulatory context. In the third part there is an economic analysis of investments in energy efficiency. The fourth part considers the different options that distribution companies face in order to reach the energy efficiency targets. The fifth part shows the results obtained after the first year of operation of the mechanism. Finally, we propose some possible modifications to the scheme adopted in Italy considering the results obtained and the alternative solutions already applied in France and United Kingdom [it

Fiber-Reinforced Polymer Nets for Strengthening Lava Stone Masonries in Historical Buildings

Santi Maria Cascone

2016-04-01

Full Text Available The strengthening of masonries is a crucial step in building restoration works because of its relevance, mostly with regard to the improvement of building seismic behavior. Current building technologies are based on the use of steel nets which are incorporated into cement plasters. The use of steel has a number of contraindications that can be solved by using composite materials such as glass fiber nets, which have high mechanical characteristics and lightness, elasticity, corrosion resistance, and compatibility with lime plaster. Building interventions, that take into account the application of glass fiber nets, are very sustainable from several points of view, e.g., material production, in situ works, economic cost and durability. In Italy, several experiments have been carried out in situ with the aim of testing the mechanical characteristics of masonries which have been treated with fiber-reinforced polymer (FRP nets. This paper deals with a series of in situ tests carried out during the restoration works of an important historical building located in Catania (Sicily, Italy. The results achieved are largely positive.

The cyst banks of 6 coastal hypersaline lakes of South-East Europe have been investigated. The study concerned the bottom sediments of Khersonesskoe and Koyashskoe lakes in the Crimea (Ukraine), Nartë saltworks (Albania), Vecchia Salina at Torre Colimena (Apulia, Italy), Pantano Grande and Pantano Roveto at Vendicari (Sicily, Italy). A total of 19 cyst types were recognised. The cyst banks of lakes were found to be well separated in the representation derived from a statistical multivariate data analysis. For all the lakes examined a comparison was possible between the resting community in sediments (cyst bank) and the active one in the water. The cyst banks contained more species than those recorded over a multi-year sampling effort in the water column. The study of cyst hatching, performed on 5 cyst types under lab conditions, demonstrated that cysts do not hatch under the same conditions. Furthermore, each cyst type shows a wide range of preferential hatching conditions, which allow us to confirm the ecological generalism of salt lake species. PMID:19292906

The point of view adopted is to better define the precipitation microphysical properties (in particular, the Drop Size Distribution, DSD, and its moments, which are deeply related to the cloud system that generates the precipitation events.

In fact the prevailing Stratiform nature is related to Licata station, while for Surigheddu and for Rotondella the nature is mainly Convective. This distinction is related to the presence of drops of bigger dimensions and more intense precipitations in the latter case, while, in the former case, a prevalence of smaller drops and a less intense precipitation is recorded. This confirms the distinctive belonging to three different climatic regions, as indicated in the study by Brunetti et al. (2006. Our findings are important in the framework of desertification studies, because the cause of desertification can be related either to fertile soils removal (in the case of Convective events or to lack of precipitated water (in the case of Stratiform events.

2015-05-01

Full Text Available Much attention is currently devoted at upgrading our knowledge on biodiversity and functioning of deep water ecosystems. Information is constantly enriched by researchers, even from basins as the long-studied Mediterranean Sea. In such a perspective, we studied meiobenthic and nematode communities inhabiting muddy sediments from three different habitats at bathyal depths in the Strait of Sicily: a cold-water coral site (CS in the Maltese Coral Province, a muddy bottom in the same area (MS, and a hydrocarbon imprinted pockmark site (PS in the Gela Basin. The average meiofauna density at CS (1343 ind/10 cm2 and MS (1804 ind/10 cm2 is much higher than that reported in literature for similar habitats; it is also markedly more elevated than that recorded at PS (224 ind/10 cm2. Although nematodes of the three sites show different abundances, they share similar assemblage structure. Nematodes (avg. 86% and copepods (avg. 9.3% were the most abundant meiofaunal taxa at all sites followed by annelids, kinorhynchs and turbellarians. Nematodes were composed by 21 families and 46 genera, with Terschellingia, as most abundant genus (12.4%, followed by Microlaimus (11%, Daptonema (11%, Thalassomonhystera (10.8%, Acantholaimus (9.5% and Sabatieria (8.7%. The genera Thalassomonhystera, Terschellingia, Microlaimus, Daptonema, Chromadorita, Sabatieria, and Anticoma display a dominance in at least one station. The taxonomic structure of meiofaunal communities of the studied sites is rather similar but differences in relative abundance are evident.

Wind power utilization in Italy has not been very popular until the privatization of the ENEL and introduction of subsidies for private electricity producers. The greatest interest is concentrated around large wind turbines. Therefore the Danish manufacturers with know-how within large wind turbines can establish themselves on the Italian market. Cooperation with one of the four local wind turbine manufacturers is advisable. (EG)

When probabilistic seismic hazard climbs volcanoes: the Mt. Etna case, Italy – Part 2: Computational implementation and first results

Directory of Open Access Journals (Sweden)

L. Peruzza

2017-11-01

Full Text Available This paper describes the model implementation and presents results of a probabilistic seismic hazard assessment (PSHA for the Mt. Etna volcanic region in Sicily, Italy, considering local volcano-tectonic earthquakes. Working in a volcanic region presents new challenges not typically faced in standard PSHA, which are broadly due to the nature of the local volcano-tectonic earthquakes, the cone shape of the volcano and the attenuation properties of seismic waves in the volcanic region. These have been accounted for through the development of a seismic source model that integrates data from different disciplines (historical and instrumental earthquake datasets, tectonic data, etc.; presented in Part 1, by Azzaro et al., 2017 and through the development and software implementation of original tools for the computation, such as a new ground-motion prediction equation and magnitude–scaling relationship specifically derived for this volcanic area, and the capability to account for the surficial topography in the hazard calculation, which influences source-to-site distances. Hazard calculations have been carried out after updating the most recent releases of two widely used PSHA software packages (CRISIS, as in Ordaz et al., 2013; the OpenQuake engine, as in Pagani et al., 2014. Results are computed for short- to mid-term exposure times (10 % probability of exceedance in 5 and 30 years, Poisson and time dependent and spectral amplitudes of engineering interest. A preliminary exploration of the impact of site-specific response is also presented for the densely inhabited Etna's eastern flank, and the change in expected ground motion is finally commented on. These results do not account for M  >  6 regional seismogenic sources which control the hazard at long return periods. However, by focusing on the impact of M  <  6 local volcano-tectonic earthquakes, which dominate the hazard at the short- to mid-term exposure times considered
