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

    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 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.

    2009-01-01

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

  6. 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.

    2010-01-01

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

  8. A tectonomagnetic effect detected in Central Italy

    1994-06-01

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

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

The survey was carried out on 127 farms (epidemiological units, selected using a grid approach within a Geographical Information System, followed by proportional allocation. In each farm 6 buffaloes were examined in order to detect the louse presence. Parasitological examinations were performed on each buffalo at predilection sites. A total of 762 water buffaloes were examined. H. tuberculatus was found in the 11.0% (14/127 of the farms and in the 4.5% (34/762 of the animals. The presence H. tuberculatus should be routinely considered because it is a cause of serious health, production and economic damages in intensive breeding buffaloes.

    Full Text Available Rayleigh wave dispersion has been observed along the three profiles
    Trieste-Olbia, Olbia-Bologna and Olbia-Bolzano, in central-northern Italy.
    The interpretation of phase velocities indicates a crustal thickness increasing
    from East (25-30 km, Trieste-Olbia to West (30-35 km, Olbia-Bolzano.
    For each profile two values of the Moho depth are acceptable; the shallower
    one is associated with a set of models which have low velocity
    material (¡3=4.3 lcm/s just under or within a few km from the Moho;
    the deeper one still accepts low velocity material ((3=4.4 km/s under
    the Moho but does not exclude the presence of an almost normal LID
    above the low velocity channel.

    2004-06-01

    Full Text Available Tectonomagnetic field observations from absolute magnetic field level measurements were undertaken in Central Italy in an area extending between latitude 41°N and 43°N and between longitude 13°E and 15°E. Moreover,natural electromagnetic signals from a system of two VLF search coil wide-band antennas were collected at the geomagnetic observatory of L Aquila (42º23'N, 13º19'E. The analysis of these data allowed the investigation of the electromagnetic properties of the study area at different time and spatial lengthscales. Tectonomagnetic field observations were obtained comparing data simultaneously recorded at three magnetometer stations using L'Aquila Observatory as a reference for differentiation. We report on the time evolution of magnetic and electromagnetic indicators related to local and regional seismic activity.

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

  16. The continued ageing of people with AIDS in Italy: recent trend from the national AIDS Registry

    2014-09-01

    Full Text Available Introduction. In industrialized countries, the availability of highly active antiretroviral therapy (HAART caused a slow but substantial ageing of the AIDS epidemic mainly due to the longer survival of persons with HIV/AIDS which has turned HIV into a manageable, chronic disease. The number of older people with AIDS is growing in many European countries. We described the impact of AIDS among persons aged 50 years or more in Italy and compared the characteristics of these cases with those of persons diagnosed with AIDS at an age younger than 50. Methods. The source of data was the Italian AIDS Registry, from 1982 to 2011. We defined "older" persons those aged 50 years or more, and younger individuals those aged less than 50 years. We built two multivariate logistic regression models: the first one to identify factors associated with being older, and the second one to identify AIDS-defining diseases correlated with being older. Variables with a P value of < 0.05 were entered in the model. Results. Of the total AIDS cases, 10.5% were among persons older than 49 years. This proportion progressively increased from 0.0% in 1983 to 26.4% in 2011. Among older cases, the incidence of AIDS was 2.0 per 100 000 residents in 1996, then decreased to 1.4 per 100 000 in 2000 and levelled off around 1 per 100 000 residents until 2011. Compared to younger cases, older cases were more frequently males, Italians, diagnosed with AIDS in recent years, residing in Northern or Central Italy, non-injecting drug users, and late testers. Discussion. These findings stress the need for physicians to consider carefully the possibility of HIV infection among older individuals not to miss the opportunity to deliver prevention messages, offer HIV testing, and make an early diagnosis.

  17. Naturalness Consumption and Biodiversity in an Ecoregion of Central Italy

    Full Text Available Landscape naturalness and landscape biodiversity are closely connected with ecosystem sustainability. In this study, “naturalness consumption” and “induced biodiversity” created by human interference were evaluated in an ecoregion of Central Italy that represents a meaningful local example of land-use pattern in a Mediterranean environment. A core set of selected indicators and indexes applied to the database produced by GIS was used first to evaluate the landscape naturalness for each phyto-climatic unit and then to calculate the naturalness consumption. Moreover, the landscape biodiversity of each phyto-climate was evaluated, considering the ecomosaic space organization and taking into account the presence of some important ecological structures like ecotones and hedges. In the naturalness analysis, the highest naturalness consumption occurred in phyto-climates with a higher presence of cultivated areas. In the biodiversity analysis, the phyto-climates with a lower naturalness and a higher presence of agricultural land showed higher values of landscape biodiversity in comparison with the other phyto-climatic units. The results suggest that biodiversity in agro-ecosystems can compensate for naturalness consumption in terms of landscape sustainability. Indeed, natural landscapes carry out a conservative role, while more bio-diverse landscapes offer a balance between human requirements and native ecosystem conditions in a frame of co-evolutionary development.

    Sacred natural sites (SNS) are instances of biocultural landscapes protected for spiritual motives. These sites frequently host important biological values in areas of Asia and Africa, where traditional resource management is still upheld by local communities. In contrast, the biodiversity value of SNS has hardly been quantitatively tested in Western contexts, where customs and traditions have relatively lost importance due to modernization and secularization. To assess whether SNS in Western contexts retain value for biodiversity, we studied plant species composition at 30 SNS in Central Italy and compared them with a paired set of similar but not sacred reference sites. We demonstrate that SNS are important for conserving stands of large trees and habitat heterogeneity across different land-cover types. Further, SNS harbor higher plant species richness and a more valuable plant species pool, and significantly contribute to diversity at the landscape scale. We suggest that these patterns are related not only to pre-existent features, but also to traditional management. Conservation of SNS should take into account these specificities, and their cultural as well as biological values, by supporting the continuation of traditional management practices. PMID:26701326

    A 60-m-deep continental core has been drilled into a Pleistocene lacustrine succession encompassing the Brunhes-Matuyama boundary from the Sulmona tectonic basin (central Italy). The lacustrine deposits consist of a low-energy distal facies bearing a large number of tephras sourced from the peri-Tyrrhenian, ultra-potassic volcanic complexes located ~100 km westward of the basin. Basing on preliminary chronologic constraints provided by Ar/Ar datings and tephrochronology, the sediment accumulation rates are estimated in the order of ~0.2-0.3 mm/yr, thus making the Sulmona succession one of the highest-resolution potential records of the Brunhes-Matuyama transition. The magnetic mineralogy is quite homogeneous, likely consisting of dominant magnetite with scattered occurrence of greigite. The concentration of para- and ferromagnetic minerals in sediments, as documented by susceptibility measurements, shows slight variations that we correlate to climatic oscillations. On the whole a complete glacial-interglacial-glacial cycle is recognizable in the cored succession and it is ascribed to the MIS20-MIS18 interval. Paleomagnetic investigations on discrete samples documented the B-M transition shortly after the onset of the MIS19 interglacial stage. A larger stratigraphic interval has been then sampled by means of u-channels and measured at 1-cm spacing, with the aim to recover a high-resolution record of the polarity transition. The data show drastic changes in paleomagnetic directions along a ~6-m-thick core section. According to the preliminary interpretation, the B-M transition should occur in the uppermost ~2 m of this stratigraphic interval and it is preceded by a normal polarity interval, whose meaning is presently under investigation.

  1. GIS modeling for canine dirofilariosis risk assessment in central Italy

    2008-05-01

    Full Text Available A survey was conducted in an area of central Italy in order to study the prevalence of Dirofilaria immitis and D. repens in dogs. Blood samples were collected from 283 dogs and examined using a modified Knott’s technique. In addition, in order to detect D. immitis occult infection, 203 serum samples were also analysed for D. immitis antigen detection. The results were analyzed in order to evaluate the behavioural and attitudinal risk factors. A geographical information system (GIS for the study area was constructed, utilizing the following data layers: administrative boundaries, elevation, temperature, rainfall and humidity. Microfilariae were detected in 32 of the 283 dogs surveyed, constituting a total Dirofilaria prevalence of 11.3%. In particular, 20 dogs (7.1% were positive for D. immitis and 12 dogs (4.2% for D. repens microfilariae. One case of D. immitis occult infection was also detected. Choroplethic municipal maps were drawn within the GIS in order to display the distribution of each Dirofilaria species in the study area. Statistical analysis showed a significant association between Dirofilaria infection and animal attitude (hunting/truffle dogs showed a higher prevalence compared to guard/pet dogs. A higher prevalence was also recorded in 2 to 5-years old dogs. Furthermore a GIS-based modelling of climatic data, collected from 5 meteorological stations in the study area, was performed to estimate the yearly number of D. immitis generations in the mosquito vector. The results of the model as depicted by GIS analysis was highly concordant with the territorial distribution of positive dogs and showed that D. immitis spreading is markedly influenced by season. The potential transmission period in the study area was found to be confined to summer months with a peak in July and August, as expected for a temperate region where summer season is the most favourable period for the parasite.

    The GPS observation of more than 350 continuous GPS stations located in the Central and Northern Italian peninsula have been analyzed in order to reconstruct the present kinematic pattern in the area. Several sites (about 100) are managed by public companies and scientific research institutions aimed at performing accurate monitoring of earth surface movements, other sites are managed by public institutions and private agencies to support mapping activities, rescue and emergency services and real-time positioning (VRS and RTK).We have processed with GAMIT software all the available data for the period 2001-2012. The network is divided into 21 sub-networks, each including at least the six common stations. The IGS precise ephemerides have been included in the processing with tight constraints, such as the Earth Orientation Parameter (EOP). The daily loosely constrained solutions of the 21 clusters have been combined into a unique solution by the GLOBK software. Such solution has been then aligned into the ITRF2008 reference frame by a weighted six parameters transformation (three translation and three rotation), using the ITRF2008 coordinates and velocities of the five high quality common IGS stations (CAGL, GRAZ, MATE, WTZR and ZIMM). The sites with an observation time span less than two years have been excluded from the analysis of kinematic pattern, because it is hard to get a robust estimate of rate, seasonal signals and steps with less than two years of observation. The horizontal kinematic pattern has been analyzed in order to gain information about the present short term deformation pattern of this region. This analysis may have significant implications for the recognition of seismic zones most prone to next strong earthquakes. The vertical velocity field has been also considered in this study. It is largely recognized that vertical movements in the Central - Northern Italy may be considered as the overall result of three main causes: tectonic processes

    Three hundred and ninety-seven randomly selected households were interviewed by telephone to determine the numbers and management of owned cats and dogs in the Teramo Province of Italy. The households were selected using stratified random sampling for each municipality; municipalities were combined into coastal, central hills and mountain regions for analysis. The interviews were completed during May and June of 2004 with a response rate of 74% (397/536). Forty-six percent of households (n=181) owned pets; 15% of all households (n=60) owned cats and 33% (n=130) owned dogs. Twenty-seven of these households (7%) owned both cats and dogs. Data were provided on 91 cats evenly divided between males and females. The median age was 3 years (range 0.2-10 years). Forty-one percent of cats (36/87) entered the household as strays. Nearly half lived entirely outside. Seventy percent (62/88) had visited a veterinarian at least once; 43% (39/91) were sterilized. About 1/3 had had a litter and all litters were considered accidental rather than planned. Age, indoor/outdoor status, veterinarian visit and region were all associated with sterilization. Age, confined to a yard, veterinary visit and region were associated with allowing the cat to roam freely. Data were provided on 182 dogs. Sixty-two percent (113/181) were male, with a median age of 4 years (range newborn to 17 years) and 40% (72/181) were purebred. Almost half were acquired as a gift. Sixty-two percent (112/180) were kept entirely outside despite the fact that 82% (147/180) were considered companions rather than working dogs. Almost all of the dogs had been to a veterinarian at least once; only 20% (n=29) were sterilized. Male dogs were significantly less likely to be sterilized than females. Almost half the dogs had had at least one litter. Seventy-six percent (137/180) of dogs knew some basic commands. Sex, source and training to sit/stay/come were significantly associated with whether the dog was sterilized. Dog

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

    An ethnobotanical survey was carried out in the year 1997-1998, in the neighbourhood of the town of Chieti in the Abruzzo region (Central Italy). The information recorded in this paper has been collected by interviewing people born in the area, or who have lived there for many years, and whose knowledge of the medicinal or domestic use of plants represents a personal patrimony uninfluenced by other sources. About 80 species claimed as medicinal (not only in human therapy but also, for example, in veterinary use) and belonging to 43 families are recorded; only the use of the plants identified with certainty is reported. The study pointed out that the heritage of medicinal popular use of such plants, in spite of pharmaceutical technology, is still alive, not only in the memory of the elders and farmers, and that nowadays home-made remedies for simple diseases are still often used: Moreover, the uses of these plants are not only limited to therapeutic purposes, but also extend to domestic and surviving craft activities.

    On April 6, 2009, at 01:33 GMT, central Italy has been hit by a strong earthquake (Ml 5.8, Mw 6.3) representing the mainshock of a seismic sequence of over 20.000 aftershocks recorded in about five months. The event, located in the inner of the Abruzzi region just a few kilometres SW of the town of L’Aquila, has produced destructions and heavy damage in a 30 km wide area and was felt in almost Italy, as far as the coasts of Slovenia, Croatia and Albania. In all, 308 people lost their lives. A macroseismic survey was carried out soon after the earthquake by the QUEST group (QUick Earthquake Survey Team) with the aim to define, for Civil Protection purposes, the damage scenario over a territory which is densely urbanised. Damage generally depended on the high vulnerability of the buildings both for problems related to the old age of the buildings - it is the case of the historical centre of l’Aquila - and to site effects, as in some quarters of the town and in the nearby villages. Rubble-stone and masonry buildings suffered heaviest damage - a lot of old small villages almost entirely collapsed - while reinforced concrete (RC) frame buildings generally experienced moderate structural damage except in particular condition. The macroseismic effects reached intensity IX-X MCS (Mercalli-Cancani-Sieberg scale) at Onna and Castelnuovo, while many others villages reached VIII-IX MCS, amongst which the historical centre of L’Aquila. This town was investigated in detail due to the striking difference of damage between the historical centre and the more recent surrounding areas. In all, more than 300 localities have been investigated (Galli and Camassi, 2009). The earthquake has also provoked effects on natural surroundings (EMERGEO WG, 2009). Two types of phenomena have been detected: (i) surface cracks mainly observed along previously mapped faults and (ii) slope instability processes, such as landslides and secondary fractures.

    Hearing loss is one of the most prevalent health impairments associated with ageing in developed countries, and it can result in social, emotional and communication dysfunction. Hearing loss in Italy is increasing, yet, despite the availability of free hearing aids and access to qualified community-based health professionals specialising in audiology services, their uptake remains low (about 15%-20%). This paper presents an investigation of the possible reasons why older people in Italy resist adopting a hearing aid. We used the literature to identify factors influencing people with hearing loss's decision-making, and drew on the theory of reasoned action to create an explanatory model. To test our hypotheses, we applied a cross-sectional design. We developed a questionnaire including 13 items related to adopting a hearing aid. Health professionals identified 400 persons aged 60-90 who were candidates for a free hearing aid. Those willing to participate were sent a copy of the questionnaire and telephoned between August and September 2009; a total of 243 responded (response rate of 60.8%). Linear regression analysis highlighted that a person's intention to adopt a hearing aid was positively related to their attitude towards its adoption, but negatively linked to their perceived subjective norms. It was found that trust in the health professional does not moderate the relationship between a person's attitude and their intention to adopt a hearing aid, but trust mitigates the relationship between a person's perceived subjective norms and their intentions. These findings underline the importance of the potential role that the healthcare professional could play in reducing the uncertainty created by external social pressures. For this purpose, stronger collaboration between the various health professionals involved in hearing aid provision, from diagnosis to fitting, is recommended. PMID:25251979

    Maria Teresa Antognoni

    2014-03-01

    Full Text Available Anaplasma platys is a tick-borne pathogen causing the Infectious Canine Cyclic Thrombocytopenia. The pathogenesis of this disease is not yet well understood, due to the wide variety of clinico-pathological patterns described worldwide and to the high prevalence of co-infections with other vector-borne pathogens occurring in endemic areas. The present paper reports 3 cases of infection by A. platys occurring in dogs native to Central Italy, considered a non-endemic area to date. Infections were initially diagnosed based on clinical data and observation of morulae within platelets and then confirmed by biomolecular techniques. Moreover, two dogs showed an immune-mediated hemolytic anemia, as yet not described in literature in association with A. platys infection. The symptoms and the pathological findings observed will be discussed, as well as the importance to include this pathogen in the differential diagnosis of tick-borne diseases even in Central Italy.

    In the Early Holocene, the central Marches (Italy) underwent a widespread development of forest cover and soils which drastically reduced slope degradation and related aggradation processes in riverbeds. In such conditions, streams deeply incised the previous alluvial sediments. In the Apennine sectors, linear erosion was locally prevented by the growth of travertine dams in correspondence with river channel knickpoints and waterfalls. Fluvial deposition prevailed in the peri-Adriatic hilly b...

    Full Text Available The purpose of this study was to provide reference data on the growth and population structure of brown trout Salmo (trutta trutta Linnaeus, in Central Italy. Standards for growth (percentiles and a standard growth model were developed from the von Bertalanffy growth model by using length-at-age data obtained from 122 sampling sites in the River Tiber basin. Length-frequency indices provide a numeric estimation for deviations of the population structure from a balanced population. We adapted the traditional North American Relative Stock Density (RSD and Proportional Stock Density (PSD indices to brown trout populations in Central Italy by means of two methods. In the first method, the benchmarks of length categories were established by using percentages applied to the largest individual in the dataset. In the second method, asymptotic length and size at maturity were used to define the length categories for index calculation. Both methods were tested on length-frequency data from 263 sampling sites in the River Tiber basin. The results showed that the PSD calculated by the first method provided a better insight into the population structures of brown trout. These results provide tools that will help ichthyologists and fish managers to compare the growth and population structure of brown trout throughout Central Italy.

    Full Text Available We present the results of the application of a recently proposed model to determine landslide hazard. The model predicts where landslides will occur, how frequently they will occur, and how large they will be in a given area. For the Collazzone area, in the central Italian Apennines, we prepared a multi-temporal inventory map through the interpretation of multiple sets of aerial photographs taken between 1941 and 1997 and field surveys conducted in the period between 1998 and 2004. We then partitioned the 79 square kilometres study area into 894 slope units, and obtained the probability of spatial occurrence of landslides by discriminant analysis of thematic variables, including morphology, lithology, structure and land use. For each slope unit, we computed the expected landslide recurrence by dividing the total number of landslide events inventoried in the terrain unit by the time span of the investigated period. Assuming landslide recurrence was constant, and adopting a Poisson probability model, we determined the exceedance probability of having one or more landslides in each slope unit, for different periods. We obtained the probability of landslide size, a proxy for landslide magnitude, by analysing the frequency-area statistics of landslides, obtained from the multi-temporal inventory map. Lastly, assuming independence, we determined landslide hazard for each slope unit as the joint probability of landslide size, of landslide temporal occurrence, and of landslide spatial occurrence.

    Full Text Available Following the increase in protected territories over recent years, emphasis has been laid on improving nature conservation and management effectiveness. In particular, special attention has been given to areas where the interaction between people and the environment has produced a distinct character, rich in both ecological and cultural values. Such areas are known as Protected Landscapes and require a special planning and management focus, in which relevant weight is given to local people. The aim of this research is to present a planning process case study in central Italy (Tuscania, north of Rome, where the protected area plan tackles nature conservation and environmental concerns (i.e. water quality, soil conservation, landscape restoration etc.. The results are of general interest because they are the fruit of an experience in debating and improving both the plan’s contents and planning methods. In particular, they show: i the primary role of local people in the various phases of planning, including delicate decisions such as the park’s limits and its buffer area; ii that a protected area plan should not be strictly prescriptive, but should have the role of a strategic master plan; iii that the protected area policy should be emphasised in the park regulations document, rather than in rigid territorial zoning.

This type of pain may also impair activities of daily living and further worsen quality of life, negatively influencing the rehabilitation process. The prevalence of CSPS in the literature is highly variable (1%–12% according to different studies, and this variability could be influenced by selection criteria and the different ethnic populations being investigated. With this scenario in mind, we performed a population-based study to assess the prevalence of CPSP and its main features in a homogeneous health district (Rimini, Italy, including five hospitals for a total population of 329,970 inhabitants. From 2008 to 2010, we selected 1,494 post-stroke patients and were able to interview 660 patients, 66 (11% of whom reported pain with related tactile and thermal hyperesthesia, accompanied by needle puncture, tingling, swelling, and pressure sensations. Patients reported motor impairment and disability, which influenced their working ability, rehabilitation, and social life. Despite this severe pain state, there was a high percentage of patients who did not receive adequate treatment for pain. Keywords: stroke, central post-stroke pain, disability

  8. Performances of the UNDERground SEISmic array for the analysis of seismicity in Central Italy

    R. Scarpa

    2006-06-01

    Full Text Available This paper presents the first results from the operation of a dense seismic array deployed in the underground Physics Laboratories at Gran Sasso (Central Italy. The array consists of 13 short-period, three-component seismometers with an aperture of about 550 m and average sensor spacing of 90 m. The reduced sensor spacing, joined to the spatially-white character of the background noise allows for quick and reliable detection of coherent wavefront arrivals even under very poor SNR conditions. We apply high-resolution frequency-slowness and polarization analyses to a set of 27 earthquakes recorded between November, 2002, and September, 2003, at epicentral distances spanning the 20-140 km interval. We locate these events using inversion of P- and S-wave backazimuths and S-P delay times, and compare the results with data from the Centralized National Seismic Network catalog. For the case of S-wave, the discrepancies among the two set of locations never exceed 10 km; the largest errors are instead observed for the case of P-waves. This observation may be due to the fact that the small array aperture does not allow for robust assessment of waves propagating at high apparent velocities. This information is discussed with special reference to the directions of future studies aimed at elucidating the location of seismogenetic structures in Central Italy from extended analysis of the micro-seismicity.

  9. Investigating seismogenic faults in Central and Southern Apennines (Italy: modeling of fault-related landscape features

    Directory of Open Access Journals (Sweden)

    P. Burrato

    1996-06-01

    Full Text Available The direct identification of seismogenic structures in Southern Italy is often a difficult task, since finding seismogenic faults with clear surface expression associated is unlikely, even if they are the source of large magnitude earthquakes. A possible way to solve this problem is the investigation of a series of features of the surface landscape that could be attributed to repeated movements along a fault. In this paper we investigated the drainage, ancient coastlines, marine terraces and recent deposits of three different active tectonic basins in central and Southern Italy. The combination of the modeling of these fault-related landscape features with historical and seismological data better constrained the geometry of the seismogenic faults responsible for three large magnitude historical events in the studied areas. The results show that in this section of the peninsula seismogenesis is often connected with blind almost pure dip-slip normal faults; the long-term activity of these faults produces intermontane basins or coastal plains that are sinking relative to the surrounding areas; the application of this methodology emphasises the importance of geological and geomorphological studies for the recognition of seismogenic faults and for a complete assessment of the seismic hazard in Italy.

    Full Text Available Stevia rebaudiana Bertoni produces a variety of high-potency low calorie sweeteners in its’ leaf tissue. The aim of this work was to evaluate the productive potential of two different Stevia rebaudiana genotypes and the characteristics of the production of the plant obtained through different cultivation methods, in central Italy. For several years (1992-2000 agronomic trials on Stevia rebaudiana cultivated in the littoral area near Pisa (Italy carried out. In 1992 two different genotypes of Stevia (B1 and B2 transplanted in silt-loam soil; in 1996 other plants from B2 genotype, produced by vegetative process (micropropagation, were transplanted in the same field. In the period from 1992-1999 the production of leaves from both genotypes increase as of the third year and the ratio leaf-aerial plant, after the peak in the third year, tends to diminish. Except the first year (1997 there were not recorded statistically significant differences between the two propagation methods employed in relation to leaf production. The quantity of leaves produced from a single harvest was less than resulting from two cuttings and the micropropagation plants produced a larger amount of leaves than those from cutting. The leaf-stem ratio was to become an interesting morphological and production characteristic parameter of the plant. Stevia rebaudiana appears particularly suited for the cultivation environment of central Italy. A particular positive aspect that must be considered in these regions is that Stevia can be grown successfully as poliannual species because crop survival over the winter is high. The results obtained show that this species is economically profitable until the 5th or 6th year of cultivation. At our latitudes is also necessary to establish a program of genetic improvement in order to develop earlier varieties that can guaranty an optimum qualitative and quantitative seed production.

  15. Epiphytic lichens as sentinels for heavy metal pollution at forest ecosystems (central Italy)

    International Nuclear Information System (INIS)

    Epiphytic lichens were useful as an early warning system for changes in forest ecosystems. - The results of a study using epiphytic lichens (Parmelia caperata) as sentinels for heavy metal deposition at six selected forest ecosystems of central Italy are reported. The woods investigated are characterized by holm oak (Quercus ilex), turkey oak (Quercus cerris) and beech (Fagus sylvatica) and represent the typical forest ecosystems of central Italy at low, medium and high elevations, respectively. The results showed that levels of heavy metals in lichens were relatively low and consequently no risk of heavy metal air pollution is expected for the six forest ecosystems investigated. However, for two of them there are indications of a potential risk: the beech forest of Vallombrosa showed signs of contamination by Pb as a consequence of vehicle traffic due to the rather high touristic pressure in the area, and the holm oak forest of Cala Violina showed transboundary pollution by Mn, Cr and Ni originating from the steel industry in Piombino. Epiphytic lichens proved to be very effective as an early warning system to detect signs of a changing environment at forest ecosystems

A system of two VLF search coil wide-band antennas, working in two different frequency bands, at the L’Aquila Observatory, monitors possible electromagnetic effects related to seismic events occurring in Central Italy. Absolute magnetic field observations and VLF signals have been collected for several years. In particular the tectono-magnetic network started its operations in 1989. In this paper we report on the time variation of above mentioned data for the most recent years 2002 and 2003, also in connection with older measurements time series; we also report on seismic activity recorded in this area by the national seismic network. In the above mentioned time interval, no strong earthquake activity was recorded, and at the same time no clear evidence for magnetic or electromagnetic signals related to seismic events was found.

  17. Priority persistent contaminants in people dwelling in critical areas of Campania Region, Italy (SEBIOREC biomonitoring study)

    International Nuclear Information System (INIS)

    To investigate if protracted living in degraded environments of the Caserta and Naples provinces (Campania Region, Italy) had an impact on exposure of local people, highly toxic persistent contaminants were measured in blood, blood serum, and human milk of a large number of healthy donors. Sampling was carried out from 2008 to 2009. Blood was collected from over 850 20–64-year old donors; by pooling, 84 blood and 84 serum samples were obtained. Milk was donated by 52 mothers: specimens were pooled into six samples. Polychlorodibenzodioxins (PCDDs), polychlorodibenzofurans (PCDFs), and polychlorobiphenyls (PCBs, dioxin-like (DL) and non-dioxin-like (Σ6PCBs)), arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb) were measured in serum (organic biomarkers) and blood (metals); these chemicals and polybromobiphenyl ethers (Σ9PBDEs) were analyzed in milk. PCDD + PCDF, DL-PCB, TEQTOT, and Σ6PCB concentration ranges (medians) in serum were 6.26–23.1 (12.4), 3.42–31.7 (11.5), 10.0–52.8 (23.9) pgTEQ97/g fat, and 55.5–647 (219) ng/g fat, respectively, while in milk concentration ranges were 5.99–8.77, 4.02–6.15, 10.0–14.2 pgTEQ97/g fat, and 48.7–74.2 ng/g fat. Likewise, As, Cd, Hg, and Pb findings in blood spanned 2.34–13.4 (5.83), 0.180–0.930 (0.475), 1.09–7.60 (2.60), 10.2–55.9 (28.8) μg/L, respectively; only Pb could be measured in milk (2.78–5.99 μg/L). Σ9PBDE levels in milk samples were 0.965–6.05 ng/g fat. Biomarkers' concentrations were found to be compatible with their current values in European countries and in Italy, and consistent with an exposure primarily determined by consumption of commercial food from the large distribution system. Based on relatively higher biomarker values within the hematic biomonitoring database, the following municipalities were flagged as possibly deserving attention for health-oriented interventions: Brusciano and Caivano (As), Giugliano (Hg), Pianura (PCDDs + PCDFs), and Qualiano–Villaricca (As

    One hundred and six landraces belonging to 7 species of the Triticeae tribe were collected in central Italy by DBVBA (Perugia University), DIBIAGA (Ancona University) and ARSSA (Abruzzo Region Agricultural Development Agency) in different individual and joint missions. A few accessions were supplied by private and other public organisations. Triticum dicoccum Schubler is the most widespread species, followed by T. aestivum L., T. monococcum L., T. spelta L., T. turgidum var. durum Desf., Secale cereale L. and Hordeum vulgare L. Besides the presence of landraces reproduced by farmers over generations, information related to on-farm management and to qualitative/organoleptic traits as well as information related to their local names, uses, traditions and social context was gathered during the missions. The majority of the accessions was characterised by morphological and phenological traits and molecular markers. This work shows the presence of morpho-phenologic and genetic differences among landraces and the importance of some species in the agricultural systems and food customs of the investigated area. Particularly for emmer three well distinct landraces are present, "Farro Italia Centrale", "Farro della Garfagnana" and "Farro Italia Meridionale". Other interesting and traditional landraces are the "Solina" common wheat in Abruzzo and the "Orzo mondo" naked barley in Marche. Most of the populations are still cultivated in marginal lands and under low input or organic agronomic conditions; nevertheless, in many cases, they are found near modern varieties in conventional agriculture systems. Moreover, the in situ (on-farm) conservation of Triticeae landraces in central Italy is strictly linked to elderly farmers. PMID:12152333

    The maintenance of tick-borne disease agents in the environment strictly depends on the relationship between tick vectors and their hosts, which act as reservoirs for these pathogens. A pilot study aimed to investigate wild rodents as reservoirs for zoonotic tick-borne pathogens (Borrelia burgdorferi sensu lato (s.l.), Coxiella burnetii, Francisella tularensis, and Anaplasma phagocytophilum) was carried out in an area of Gran Sasso e Monti della Laga National Park (Abruzzi Region, central Italy), a wide protected area where, despite sporadic reports of infection in humans and animals, eco-epidemiological data on these diseases are still not available. Rodents were trapped and released at the capture site after the collection of feeding ticks and blood samples. In all, 172 ticks were collected; the most frequent species was Ixodes acuminatus (53%). Out of 88 tick pools, 11 resulted positive for C. burnetii and 13 for B. burgdorferi s.l.; the Borrelia afzelii genospecies was identified in one Ixodes ricinus tick collected from one Apodemus sp. rodent. Out of 143 blood samples, seven Apodemus spp. and five Myodes glareolus were positive for B. burgdorferi s.l. and two Apodemus spp. were positive for C. burnetii. All samples (ticks and blood) were negative for F. tularensis and A. phagocytophilum. This is the first report of B. burgdorferi s.l. in the environment for Abruzzi Region. Data on the presence of B. burgdorferi s.l. are similar to that observed in other Mediterranean countries. The present work is also the first report of C. burnetii in wild rodents in Italy. C. burnetii infection has been largely investigated in Italy in ruminant farms by serology and molecular methods, but information on ecology and on the wild cycle are still lacking. Further studies including genotyping should be performed and species-specific differences between wild rodent reservoirs of Q fever and Lyme disease agents should be investigated. PMID:26134933

  1. Efficiency Analysis of Independent and Centralized Heating Systems for Residential Buildings in Northern Italy

    Full Text Available The primary energy consumption in residential buildings is determined by the envelope thermal characteristics, air change, outside climatic data, users’ behaviour and the adopted heating system and its control. The new Italian regulations strongly suggest the installation of centralized boilers in renovated buildings with more than four apartments. This work aims to investigate the differences in primary energy consumption and efficiency among several independent and centralized heating systems installed in Northern Italy. The analysis is carried out through the following approach: firstly building heating loads are evaluated using the software TRNSYS® and, then, heating system performances are estimated through a simplified model based on the European Standard EN 15316. Several heating systems have been analyzed, evaluating: independent and centralized configurations, condensing and traditional boilers, radiator and radiant floor emitters and solar plant integration. The heating systems are applied to four buildings dating back to 2010, 2006, 1960s and 1930s. All the combinations of heating systems and buildings are analyzed in detail, evaluating efficiency and primary energy consumption. In most of the cases the choice between centralized and independent heating systems has minor effects on primary energy consumption, less than 3%: the introduction of condensing technology and the integration with solar heating plant can reduce energy consumption by 11% and 29%, respectively.

  2. Hominin responses to environmental changes during the Middle Pleistocene in Central and Southern Italy

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

    Full Text Available In sustainable agricultural systems, intercropping using living mulches (LM provides many beneficial ecosystem services. The objective of these two-year field experiments was to study the suitability of different LM options of burr medic (Medicago polymorpha L. var. anglona for organic cauliflower (Brassica oleracea L. cultivation in two sites under Mediterranean conditions. In central Italy (Experiment 1 contemporary and delayed (to crop sowings of LM were compared with a no-cover crop treatment, contrasting two local cauliflower cultivars and a F1 Hybrid. In southern Italy (Experiment 2 the sustainability of systems combining LM (anticipated and contemporary sowing compared with no-cover and organic fertilisation strategies was assessed. The aboveground biomasses dry weights of cauliflower crop (heads and residues, burr medic and weeds were separately determined. Results suggested that in Experiment 1 the LM was not able to smother weeds establishment and growth, as a consequence of early sowing, while cauliflower yield was reduced. Moreover, the genotypes behaviour was greatly influenced by the LM sowing times. In Experiment 2, irrespective of the agronomic practices applied, climatic conditions notably influenced cauliflower cultivation and also reduced the mean yield. Therefore, the recorded differences between the two experimental sites highlighted the need to tailor the LM strategies to the different environmental conditions.

    In this study, the prevalence of Toxocara spp. was evaluated in the soil of 22 public playgrounds of Ancona (Italy). The public playgrounds were selected according to the different areal distribution (centre, low-lying areas centre, hilly areas suburbs) within the urban area of Ancona, central Italy. In six playgrounds there were signs restricting access for dogs; all of them were frequented by children. Parasites were found in the soil samples from 21 out of 22 playgrounds (95.5%). The most prevalent helminth found was Toxocara canis, the common roundworm of dogs. It was detected in the soil samples from 12 (54.5%) playgrounds. This study showed a low frequency of the other parasites. Our data highlight the need for improved knowledge of the relationship between humans and stray animals. Indeed several zooparasites have a role in the etiopathogenesis of common human diseases. The high environmental contamination frequency found underlines the necessity of prompt preventive public health measures, such as control of stray animals, treatment of infected pets and hygiene education of the population to increase awareness of potential zoonotic hazards.

    Understanding animal population size and its demographic features is essential to address Public Health policies as well as to provide valuable information to pet industries and veterinary practitioners. Nevertheless, official data on feline population are not available worldwide. In the present study, the owned cat population size, its demographic attributes, and the ownership profiles have been investigated through a face-to-face questionnaire in a semirural area of Central Italy. The human : cat ratio was equal to 6.8 (95% CI: 5.7-7.5); 29.3% of households own at least one cat. The majority of cats were living in a rural area (67.8%) and outdoors, were neutered (70.5%), and were fed with commercial food (54.8%) and they visited a veterinarian 1-2 times a year (43.3%). The cat ownership was strongly associated with people living in a rural area and owning another pet. As the cat owned population was mainly kept outdoors in rural areas, the possible relation between the owned and the stray animals is worthy to be monitored in future researches. Our study revealed that the feline owned population was larger than expected and that social and economic human factors do not influence the cat ownership. Health Authorities and veterinary practitioners should promote responsible ownership to increase the veterinary care, to intensify the official identification, and to properly manage the outdoor lifestyle.

  6. Ag-110m in fungi in Central Italy after the Chernobyl accident

    International Nuclear Information System (INIS)

    Results are presented for the concentrations of 110mAg measured in Lycoperdon and Agaricus fungi and soil samples in Central Italy from September 1986 to October 1989 along with radiocaesium results and 110mAg/137Cs ratios. Following the Chernobyl accident in spring 1986, 110mAg activity in the fungi collected in autumn 1986 was undetectable but samples collected in 1988 and 1989 showed a remarkable abundance of 110mAg. 110mAg was present in soils in 1986 so it is suggested that it was not available to fungi then because of its chemical form and because of the lack of rainfall during summer 1986.

    Sandy shores are generally considered important sinks for marine litter and the presence of this litter may represent a serious threat to biotic communities and dune integrity mostly due to cleaning activities carried out through mechanical equipment. In spring (April-May) 2012 we sampled 153 2×2m random plots to assess the spatial distribution patterns of litter on Central Italy sandy shores. We analysed the relationship between the presence of litter and coastal dune habitats along the sea-inland gradient. Our results showed that the most frequent litter items were plastic and polystyrene. Differences of marine litter spatial distribution were found between upper beach and fore dune habitats and fixed dune habitats: embryo dune and mobile dune habitats show the highest frequency of litter, but, surprisingly, marine litter did not impact fixed dune habitats, these possibly acting as a natural barrier protecting the inner part of the coast from marine litter dispersion.

    The measuring stations of a geophysical network are often spatially distributed in an inhomogeneous manner. The areal inhomogeneity can be well characterized by the fractal dimension D_H of the network, which is usually smaller than the euclidean dimension of the surface, this latter equal to 2. The resulting dimensional deficit, (2-D_H), is a measure of precipitating events which cannot be detected by the network. The aim of the present study is to estimate the fractal dimension of a rain-gauge network in Tuscany (Central Italy) and to relate its dimension to the dimensions of daily rainfall events detected by a mixed satellite/radar methodology. We find that D_H = 1.85, while typical summer precipitations are characterized by a dimension much greater than the dimensional deficit 0.15.

    The present study aimed to preliminary evaluate the occurrence of fungi in 40 specimens of trapped pollen collected from April - September 2015 in 40 apiaries from Tuscany (Central Italy). Cultural and microscopical examinations allowed the recognition of Cladosporium sp., Alternaria sp., Humicola sp. Mucoraceae and Acremonium sp. Penicillium brevicompactum, Penicillium chrysogenum, Aspergillus flavus , Aspergillus nidulans, Aspergillus niger and Aspergillus terreus were also identified. Yeasts and Fusarium spp. were not isolated. All pollen specimens were positive for at least one fungal isolate. Total CFU per gram ranged from 4-568. Aspergillus and Penicillium were obtained from 8 (20%) and from 22 (55%) pollen samples, respectively, associated in 4 cases (10%). The recovery of storage fungi such as Aspergillus and Penicillium in trapped pollen presents a potential risk for human health and attention should be paid to all stages of the post-harvest process.

    Over the past century farming activity has intensified worldwide, characterized by an increasing dependence on external inputs and on land conversion. Although the intensification of agriculture has increased productivity, the sustainability of agroecosystems has also been compromised. The objective of this study is to build multivariate relationships between farm structural characteristics and farm performance to highlight the relative costs and benefits of four main farming systems in Central Italy: organic, conventional, mixed and non-mixed farms. Results show that the relationship between cropping diversity and agroecological sustainability is associated to a mixed versus non-mixed farm management dichotomy, not to organic or conventional farming practices. The presence of livestock appears to have played an important role as an economic lever for diversifying the farm cropping system. PMID:22265812

    2005-07-01

    Full Text Available Attributing the term bioindicator to a species complex such as Austropotamobius pallipes is complicated, considering that the meaning given to a bioindicator can vary according to the geographic position, and that A. pallipes species complex has been divided into 2 species and 5 subspecies, the possibility of using A. i. meridionalis as a bioindicator in watercourses of Central Italy was evaluated. To this end, we analysed the structure and abundance of a number of crayfish populations and then compared them to the water quality of the corresponding watercourses, using E.B.I. (Extended Biotic Index. This index provides information on water quality through an analysis of the macrobenthos community. The watercourses are assigned to various classes (from I to V, increasing the degrees of alteration. This study was carried out in several watercourses near Rome. The abundance of crayfish was found to be greatest in those tracts that are assessed as class I, where the populations seem well structured with individuals of various sizes and the sex ratio is approximately 1:1. In contrast, in class II we found a reduced presence of specimens, mostly in bad conditions. No crayfish specimens were observed in watercourses designated as class III. In light of these preliminary results, it does not seem possible to consider A. i. meridionalis as a bioindicator, given that one of the typical characteristics of a biological indicator (wide distribution is not met. Though these results illustrate the possibility of using A. i. meridionalis populations as an excellent monitoring instrument in Central Italy.

  12. Soil Sampling Strategy and Geostatistics to Evaluate Soil Quality in Central Italy

    International Nuclear Information System (INIS)

    The European Framework Directive on soil protection identified soil organic matter (SOM) decline in southern Europe as one of the most serious soil degradation processes among the eight main soil threats (CEC, 2006). SOM affects the chemical, physical and biological properties of the soil, and is a key indicator of soil quality and fertility. Besides providing nutrients and a habitat for soil organisms, organic matter helps to bind soil particles into aggregates, and in improving the soil water holding capacity. However, global warming is expected to accelerate SOM decomposition and increase the atmospheric CO2 concentrations that contribute to global climate change. As SOM represents the major reservoir for soil organic carbon (C) in the global C cycle, evaluating soil C capture (sequestration), storage and redistribution at various scales is of pressing concern for soil protection and in 'global warming' mitigation strategies. The problem of SOM depletion is of particular concern in central and southern Italy due to high temperature and reduced soil moisture (Mediterranean climatic conditions) that accelerate SOM decomposition. Using geostatistical (Mabit and Bernard, 2007) and geographic information system (GIS) approaches, the spatial variability of various physical and chemical soil parameters (e.g. particle size distribution, organic carbon content and total nitrogen content) was investigated under Mediterranean climatic conditions in central Italy in the Abruzzo Region (area of 100 km2). The results of 250 geo-referenced soil sampling points were interpolated by means of Ordinary Kriging (OK) to produce contour maps of the distribution of soil texture, SOM content (related to texture) and soil C/N ratios.

No animal was positive for Trichinella larvae. According to our results, Tuscany can be considered a low-risk area for trichinellosis in the fox. In this region the presence of the parasite cannot be ruled out, two cases of infection being reported in 1993. Riassunto Epidemiologia della trichinellosi della volpe (Vulpes vulpes in Toscana (Italia centrale. Nel corso degli anni 2004-2005, 112 volpi (Vulpes vulpes e 4 tassi (Meles meles sono stati catturati ed esaminati per la presenza di infestione da Trichinella in differenti aree della Toscana (Italia centrale. L'indagine di laboratorio è stata condotta mediante digestione artificiale tramite Stomacher. Nessun animale è risultato positivo. Da questi risultati si può ritenere la Toscana una regione a basso rischio di infezione. La presenza del parassita non può però essere esclusa totalmente. Infatti, nel 1993 sono stati riportati due casi di infestione.

    Mud volcanoes are common geological phenomenons observed worldwide as in Italy. They are well described in the scientific literature for their morphological, tectonic and hydrogeological features. They represent not only a relevant geological and geomorphological interest but also not negligible elements of hazard and risk associated with the presence of soft and pliable sediments and with the possible unexpected emission of gas and mud. Therefore, the understanding of their structure and hydrogeological circuits in the subsurface is an important key to define hazard and risk conditions in the adjacent areas. This paper deals with a multidisciplinary study including geophysical and hydrochemical surveys undertaken at the Pineto (central Italy) mud volcano site to achieve an interpretative conceptual model explaining the shallow upward migration of deep mud fluids. Shallow electrical and seismic imaging of the mud volcano was obtained using two dimensional and three dimensional (2D-3D) electrical resistivity tomography and 2D reflection seismic surveys. The hydrochemical properties of the rising fluids were assessed by means of seasonal measurements of the chemical-physical parameters, the concentrations of major ions, and some natural isotopes. This mud volcano or mud lump appears as a dome of about 15 × 10 m in size. The height of the crater is 2 m approximately, while the diameter of the crater is 2.5 m. Emission of fluids and solids (cold brine, mud, gas) occurs from this crater. Upper Pliocene-lower Pleistocene foredeep pelitic deposits (over-compacted clays with silty-sandy levels) overlain by clayey-silty deposits crop out in the area. The survey results seem to reveal that the uprising of deep fluids does not occur exactly below the mud volcano at present. Instead, a high conductivity body is present within a fractured zone in the pelitic deposits at 60 m approximately to the ENE. The probable occurrence of a high permeability layer approximately between 20

The responses to questions on political engagement and voting behaviour show an increased interest in politics and a tendency to support political extremes. Yet, the return to pronounced ideologies can only be found on the level of discussion and does not result in an act...

    2013-03-01

    In this work we report a GPR study across a tectonic discontinuity in Central Italy. The surveyed area is located in the Castelluccio depression, a tectonic basin in the Central Apennines, close to the western border of the Mt. Vettore. Its West flank is characterised by a set of W-dipping normal faults, considered active and capable of generating strong earthquakes (Mw = 6.5, Galli et al., 2008). A secondary fault strand, already studied with paleo-seismological analysis (Galadini and Galli, 2003), has been observed in the Quaternary deposits of the Prate Pala alluvial fan. We first defined the survey site using the data available in literature and referring to topographic and geological maps, evaluating also additional methodologies, such as orthophoto interpretation, geomorphologic analysis and integrating all the information in a GIS environment. In addition, we made extensive use of GPR modelling, reproducing the geometric characteristics of the inferred fault area and interpreting the synthetic profiles to recognise local geophysical indications of faulting on the radargrams. Finally, we performed a GPR survey employing antennas with different frequencies, to record both 2D Common Offset profiles and Common Mid Point (CMP) gathers for a more accurate velocity estimation of the investigated deposits. In this paper we focus on the evaluation of the most appropriated processing techniques and on data interpretation. Moreover we compare real and synthetic data, which allow us to better highlight some characteristic geophysical signatures of a shallow fault zone.

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

    A cross-sectional telephone survey of randomly selected households examined the extent and types of problems associated with free-roaming dogs and cats in the Teramo province of Italy. The households were sampled randomly within each municipality; municipalities were combined into coastal, central hills and mountain regions for analysis. The survey was conducted in May and June of 2004 with a response rate of 74% (397/536). Ninety percent of respondents (N=356) believed that free-roaming dogs and cats were a problem. They were most commonly concerned about personal safety, followed by animal welfare, public health and environmental sanitation. Sixty-nine percent of respondents (274) actually saw free-roaming dogs or cats where they live. While dogs were most commonly seen, cats were seen in greater numbers. Overall, 10% (39/297) and 5% (21/397) of respondents cared for free-roaming cats and dogs, respectively. Two-thirds of the respondents (251/397) believed that animals were abandoned because the owners lost interest. About 2/3 of respondents (251/397) reported that the community government should have the responsibility for dealing with free-roaming dogs and cats. The respondents supported the idea of building more shelters and controlling the birth rate as control measures rather than euthanizing dogs and cats. The results suggest that free-roaming dogs and cats are a very common sight in this part of Italy with substantial concerns by the residents. However, concerns about the animals' welfare were clearly raised, supporting the laws that make it illegal to euthanize a healthy dog or cat in Italy. Using the information from this study, research on the underlying causes of abandonment of dogs and cats or failing to sterilize them should be undertaken to begin to address this problem. Further, national and regional funding must be provided to support existing laws which should help protect and eventually decrease the numbers of free-roaming and homeless dogs and

The present study is aimed at assessing growth performance of selected eucalypt hybrid clones for SRWC in three Italian sites (Massama, Sardinia; Mirto, Calabria; Rome, Latium compared with Eucalyptus camaldulensis, the most commonly cultivated eucalypt species in Italy. The study identified eucalypt clones with stable and high performance between several alternatives. Results pointed out the declining growth performance observed in the second rotation compared with the first cycle. This is due to the cultivation model, age rotation and harvesting method adopted, which negatively affect the available soil nutrients’ content. The clone/site interaction as for basal area growth at the three investigated sites, suggests a significantly different clones’ performance among sites. Viglio and Velino clones showed the best overall performance and are suggested to be used over the large scale SRWC in central and southern Italy.

    In this work, we face the definition of a subsoil model aimed at the local seismic response assessment of the Stracciacappa maar (Sabatini Volcanic District, central Italy) (e.g., De Rita and Zanetti, 1986; Marra et al., 2014). The pyroclastic succession of Stracciacappa records two main hydromagmatic eruptive phases ended about 0.09 Ma ago (e.g., Sottili et al., 2010). The preserved crater, with a diameter of about 1500 meters and a crater floor of about 30-40 m, hosted a lake until it was drained in AD 1834. In the framework of the cooperation between CNR IGAG and Italian Department of Civil Protection (DPC) of the Presidency of Council of Ministers (DPC funds 2014), a multidisciplinary approach including detailed stratigraphic and geophysical study has been carried out in the Stracciacappa maar and surrounding areas. New geological map and cross sections illustrate the complex geometric relationships between the thick pyroclastic surge succession, showing diffuse sandwave structures, and even meter-sized lava ballistic. A composite interdigitation between lacustrine and epiclastic debris sediments fills the crater floor. A continuous coring borehole was drilled inside the crater, 45 meters deep from the wellhead, with sampling of undisturbed samples. In addition, four MASW and one SCPTU test were carried out, in order to define the velocity profile of the s-waves within the lacustrine deposits. This Vs profile was then extended at higher depths by using the results of four 2D seismic passive arrays. Moreover, in order to define the resonance frequency of sedimentary covers via the HVSR technique, twenty-eight measurements were carried out with digital sensor Tromino® and seven measurements were performed with a Lennartz® Le-3D/5s sensor with Lennartz Marslite® digitizer. Finally, three electrical resistivity tomography tests, with a total length of about 3500 meters, were carried out with the purpose of constraining the subsoil model. Regarding the non linear

    Full Text Available The aim of this study is to investigate climate changes and human activities under the lens of palynology. Based on a new high-resolution pollen sequence (PG2 from Lago di Pergusa (667 m a.s.l., central Sicily, Italy covering the last 6700 yr, we propose a reconstruction of climate and landscape changes over the recent past in central Sicily. Compared to former studies from Lago di Pergusa (Sadori and Narcisi, 2001, this work provides a reconstruction of the evolution of vegetation and climate over the last millennia in central Sicily, indeed completing previous results with new pollen data, which is particularly detailed on the last 3000 yr. Joint actions of increasing dryness, climate oscillations, and human impact shaped the landscape of this privileged site. Lago di Pergusa, besides being the main inland lake of Sicily, is very sensitive to climate change and its territory was inhabited and exploited continuously since the Palaeolithic. The lake sediments turned out to be a good observatory for natural phenomena that occurred in the last thousands of years. Results of the pollen-based study are integrated with changes in magnetic susceptibility and a tephra layer characterization. The tephra layer was shown to be related to the Sicanians' event, radiocarbon dated at 3055 ± 75 yr BP (Sadori and Narcisi, 2001. We performed palaeoclimate reconstructions by MAT (Modern Analogues Technique and WAPLS (Weighted Average Partial Least Square. Palaeoclimate reconstructions based on the core show important climate fluctuations throughout the Holocene. Climate reconstruction points out four phases of cooling and enhanced wetness in the last three millennia (2600–2000, 1650–1100, 850–550, 400–200 cal BP, corresponding to the periods between 650–50 BC, and 300–850, 1100–1400, 1550–1750 AD, respectively. This appears to be the evidence of local responses to global climate oscillations during the recent past.

    Many works carried out in the last decades have shown that the pollen season for taxa flowering in winter and spring, in temperate regions, has tended to be earlier, probably due to the continuous rise in temperature. The mean annual temperature in Perugia, Central Italy, was about 0.5 °C higher in the last three decades compared with that registered from 1952 to 1981. The increase of temperature took place mainly in winter and spring, while no significant variation was recorded during the summer and autumn. This scenario shows variations in the timing and behavior of flowering of many spontaneous plants such as grasses, whose phenology is strongly influenced by air temperature. This work reports fluctuations in the airborne grass pollen presence in Perugia over a 33-year period (1982-2014), in order to study the influence of the warming registered in recent years on the behavior of pollen release of this taxon. The grass pollen season in Perugia typically lasts from the beginning of May to late July. The start dates showed a marked trend to an earlier beginning of the season (-0.4 day/year), as well as a strong correlation with the average temperatures of March and April. The peak is reached around 30th May, but the annual pollen index (API) is following a decreasing trend. The correlation between starting dates and spring temperatures could be interesting for the constitution of a forecasting model capable of predicting the presence of airborne grass pollen, helping to plan therapies for allergic people.

  6. A geomorphological approach to the estimation of landslide hazards and risks in Umbria, Central Italy

    Directory of Open Access Journals (Sweden)

    M. Cardinali

    2002-01-01

    Full Text Available We present a geomorphological method to evaluate landslide hazard and risk. The method is based on the recognition of existing and past landslides, on the scrutiny of the local geological and morphological setting, and on the study of site-specific and historical information on past landslide events. For each study area a multi-temporal landslide inventory map has been prepared through the interpretation of various sets of stereoscopic aerial photographs taken over the period 1941–1999, field mapping carried out in the years 2000 and 2001, and the critical review of site-specific investigations completed to solve local instability problems. The multi-temporal landslide map portrays the distribution of the existing and past landslides and their observed changes over a period of about 60 years. Changes in the distribution and pattern of landslides allow one to infer the possible evolution of slopes, the most probable type of failures, and their expected frequency of occurrence and intensity. This information is used to evaluate landslide hazard, and to estimate the associated risk. The methodology is not straightforward and requires experienced geomorphologists, trained in the recognition and analysis of slope processes. Levels of landslide hazard and risk are expressed using an index that conveys, in a simple and compact format, information on the landslide frequency, the landslide intensity, and the likely damage caused by the expected failure. The methodology was tested in 79 towns, villages, and individual dwellings in the Umbria Region of central Italy.

    Full Text Available The Bastardo Basin is one of the classics Apenninic intermontane basins of central Italy. They are en-closed tectonic basins (graben and semigraben with high anthropization, but with high vulnerability, too (seismic, hydrogeological and geomorphological. The paper concerns some aspects about slope instability in the Bastardo Basin as part of a wider research, which aims to actually define the characteristics of the liability to landslides of the Apenninic intermontane basins. In particular lithological, stratigraphical and hydrogeological conditions are analysed under which a landslide near village of Barattano has developed. This mass movement, at different times, produced partial or total occlusion of the torrent Puglia. Here geognostic investigations together with laboratory tests and subsequent monitoring of landslide area were carried out.  A back analysis, based on limit equilibrium solutions for the factor of safety of the slope, provided the residual strenght properties of the soil mass along the sliding surface.   The landslide of Barattano is representative of a very frequent situation (in terms of type, factors and causes of the movement, possible development of the movement not only within Bastardo Basin, but in general within Apenninic intermontane basins, too.  The study of landslide and the design of appropriate remedial measures are of great importance in terms of prevention and mitigation of geologic-hydraulic risk in Apenninic intermontane basins.

    2004-04-01

    In this paper, 2D thermo-mechanical models with crustal deformation, driven by subduction, are performed to test the geodynamical scenario of a slab-retreat for the Northern Apennines chain (Central Italy). In the models, the lithosphere is regarded as a non-linear Maxwell visco-elastic body capable of brittle failure at low pressure and temperature and of viscous creep at elevated temperature, in Lagrangian description of deformations. We focus particularly on the time variation of the thermal field across the chain in order to evaluate the influence of temperature on the final crustal-scale deformation. Bearing in mind the difficulty to "frame" the history of an orogen in a simple, unique model and the intrinsic limitations of numerical technique, the performed models were able to give a deeper insight into the evolution of this region. On the basis of the results, we suggest that the presence of roll-back retreat together with the intrusion of an asthenospheric rise on the retreating lithosphere justify particular geological and geophysical features observed today across the chain. The models predict that this geodynamical scenario determines both the collapse of the previously formed Alpine orogen and the observed progradation of the deformation front toward east. The models also predict that the regional uplift that has interested the western sector of the chain (Tuscany), is due to the increase of temperature connected with the asthenospheric rise.

  9. Habitat Patch Diversity Evaluation for Sustainability: a Case Study of a Rural Area in Central Italy

    Full Text Available Landscape analysis is regarded as a new tool for monitoring and judging land use patterns in terms of sustainability of human activity systems at local level. A case study of evaluation for sustainability based on habitat patch diversity in an ecoregion of Central Italy is presented. In this region, ongoing land use patterns reflect both historical adaptation to local environmental constraints and positive, social-oriented management. More protective land use patterns are mostly widespread in fragile physiographic conditions like those of the mountain areas, where woodland, shrub, and grassland patches are larger and cover more than 90% of the land. This situation is regarded as a positive outcome of the traditional public ownership regime, because public lands amount to more than 70% in the mountain areas. The hilly areas, where public property drops to 28%, presents landscape metrics showing a well balanced situation between agricultural land use and protective native woods and grasslands, which provides a finegrained and harmonious Mediterranean landscape. In the low-land areas, with anthropic pressure and more favourable conditions for crop productivity, there is much more agricultural land, even if some mitigation in terms of biodiversity maintenance is offered by the presence of hedgerow ecotones. In these areas, landscape analysis is not able to supply meaningful information about cropping system design and practices which can maintain a sustainable level of soil fertility and quality of natural resources and processes, and further analysis at cropping system level should be carried out.

    The hunter-gatherer transhumance model presents foragers as specialised hunters of migratory ungulates, which moved seasonally between coastal lowlands and interior uplands. We studied six animal teeth of horse (Equus hydruntinus) and red deer (Cervus elaphus) from four different archaeological sites: the Grotta di Vado all'Arancio, Grotta di Settecannelle, Grotta Polesini and Grotta di Pozzo, in central Italy to test whether the migratory patterns and seasonal variations recorded in their teeth were consistent with expectations of the transhumance model for this region during the late Upper Palaeolithic. Sequential sub-samples of enamel were analysed from each tooth for oxygen, carbon and strontium isotope ratios to reconstruct mobility and yearly seasonal variations. The results show little evidence that these animals were moving over different geological terrains throughout the year, although small variations in Sr isotope ratios and concentrations were detected that corresponded to probable seasonal variations as shown by variability in oxygen isotope sequences. The results do, however, demonstrate that Cervus elaphus and Equus hydruntinus had different ranging behaviours, with the former moving over wider areas than the latter. This methodology produces results appropriate to assess animal migratory behaviour and, in turn, to test the consistency of proposed models of hunter-gatherer subsistence and mobility strategies.

    Full Text Available A network of low frequency electromagnetic detectors has been operating in Central Italy for more than three years, consisting of identical instruments that continuously record the electrical components of the electromagnetic field, ranging from a few Hz to tens of kHz. These signals are analyzed in real time and their power spectrum contents and time/frequency data are available online. To date, specific interest has been devoted to searching for any possible electromagnetic features which correlate with seismic activity in the same region. In this study, spectral analysis has evidenced very distinct power spectrum signatures that increased in intensity when strong seismic activity occurred near the stations of the 2009 L'Aquila earthquake. These signatures have revealed horizontally oriented electric fields, between 20 Hz to 400 Hz, lasting from several minutes to up to two hours. Their power intensities have been found to be about 1 μV/m. Moreover, a large number of man-made signals and meteorologic electric perturbations were recorded. Anthropogenic signatures have come from power line disturbances at 50 Hz and higher harmonics up to several kHz, while radio transmissions have influenced the higher kHz spectrum. Reception from low frequency transmitters is also provided in relation to seismic activity. Meteorologic signatures cover the lower frequency band through phenomena such as spherics, Schumann resonances and rain electrical perturbations. All of these phenomena are useful teaching tools for introducing students to this invisible electromagnetic world.

    Full Text Available The Province of Pesaro-Urbino, situated in the Marche Region of central Italy, can be considered to be an area at risk for Lyme disease because of its ecological features. Field data are not yet available although the disease is known to be present in neighbouring areas. During a field study lasting twelve months, ticks were collected from the vegetation, from wild cervids and also from humans who reported a tick bite at the local hospital. All ticks were identified and Ixodes ricinus specimens were tested using three different polymerase chain reaction tests for the detection of Borrelia burgdorferi sensu lato (sl. To identify the genospecies of B. burgdorferi sl, a fragment of the 5S-23S ribosomal rRNA intergenic spacer of the positive samples was amplified and then sequenced. Sequencing of the 5S-23S intergenic spacer led to the identification of two different genospecies, namely: B. burgdorferi sensu stricto and B. lusitaniae, both of which are involved in cases of human infection. Findings on the host-tick relationships and on the genospecies involved in the cycle of borreliosis confirm the suitable conditions for Lyme disease in the study area. The results concur with previous findings reported in the Mediterranean region.

    Aedes albopictus (Skuse) is an invasive mosquito species that has spread to many countries in temperate regions bordering the Mediterranean basin, where it is becoming a major public health concern. A good knowledge of the thermal features of the most productive breeding sites for Ae. albopictus is crucial for a better estimation of the mosquitoes' life cycle and developmental rates. In this article, we address the problem of predicting air temperature in three microhabitats common in urban and suburban areas and the air and water temperature inside an ordinary catch basin, which is considered the most productive breeding site for Ae. albopictus in Italy. Temperature differences were statistically proven between the three microhabitats and between the catch basin external and internal temperature. The impacts on the developmental rates for each life stage of Ae. albopictus were tested through a parametric function of the temperature, and the aquatic stages resulted as being the most affected using the specific temperature inside a typical catch basin instead of a generic air temperature. The impact of snow cover on the catch basin internal temperature, and consequently on the mortality of diapausing eggs, was also evaluated. These data can be useful to improve epidemiological models for a better prediction of Ae. albopictus seasonal and population dynamics in central-northern Italian urban areas. PMID:26314064

    Prevalence and risk factors of intestinal and lung parasites were investigated in 239 owned dogs and 81 owned cats from central Italy. In 36 dogs and 20 cats found infected by nematodes, pre and post-treatment faecal egg count (FEC) was also evaluated. About 31% of dogs and about 35% of cats resulted positive for at least one intestinal or lung parasitic species. Helminthic, intestinal and zoonotic infections resulted prevalent in examined animals. Examined dogs resulted infected by Toxocara canis (13.0%), Toxascaris leonina (1.7%), Trichuris vulpis (3.3%), Ancylostoma caninum (2.0%), Uncinaria stenocephala (1.25%), Strongyloides stercoralis (0.8%), Angiostrongylus vasorum (0.4%), Dipylidium caninum (1.25%), Taeniidae eggs (0.4%), Giardia duodenalis (3.8%), and Cystoisospora (Isospora) spp. (7.5%). Examined cats were infected by Toxocara cati (22.2%), Capillaria aerophila (1.2%), Ancylostoma tubaeformae (1.2%), U. stenocephala (3.7%), Aelurostrongylus abstrusus (1.2%), Mesocestoides sp. (1.2%), D. caninum (1.2%), G. duodenalis (1.2%) and Cystoisospora spp. (4.5%). The presence of clinical signs and the young age (less than 6 months) were identified as risk factors by univariate and multivariate statistical analysis. In 63.9% treated dogs and in 80.0% treated cats, percentages of post-treatment FEC reduction higher than 90% were found. Results obtained in this study are discussed. PMID:23265188

    Full Text Available Exploratory analysis of atmospheric pollution in a coastal forest ecosystem in central Italy - The study of spatial and temporal distribution of heavy metals in the atmosphere through the continuous assessment of deposition is of great interest for the analysis of anthropogenic pressure on the environment and the potential toxicity to humans and other living organisms. Information based on reliable estimates of heavy metals is therefore crucial for the evaluation of environmental quality. Trends in heavy metal concentration in atmospheric depositions on a coastal forest ecosystem (Castelporziano, Rome are analyzed in the present study based on a three-year monitoring field survey over three sites representative of different woodland characteristics in the area. Our results highlight both the influence of transportation processes in the short and medium distance based on the human pressure reflecting urban expansion and infrastructure development on the fringe of Castelporziano pristine forest. Further studies investigating the latent correlation with meteorological variables at various temporal scales are needed to provide a comprehensive picture of environmental conditions in a forest ecosystem subjected to increasing human pressure. Analysis of runoff water quality and the determination of other heavy metals, such as arsenic, may identify additional sources of pollution impacting soil and forest ecosystem.

    Heavy metals are subjected to monitoring in estuarine and marine water by the European Union Water Framework Directive, which requires water body health to be achieved by 2021. This is the first survey of heavy metals content in five estuaries of Marche, a region in central Italy. Results showed that total Pb and Cu concentrations decreased by 70-80%, from 1000-2000 to 100-200 ng L(-1) (Pb) and from 2000-3000 to 500-1000 ng L(-1) (Cu) from river to sea. Cd was consistently 20-40 ng L(-1). Dissolved Pb and Cu concentrations declined by 50% and 70% respectively passing from oligohaline to euhaline water, from 150 to 70 ng L(-1) and from 2000-1000 to 600-400 ng L(-1). Cd decreased slightly from ∼20 to ∼10 ng L(-1). Although such concentrations are in the range allowed by the Water Framework Directive, they far exceed (up to 10×) the ground content ceiling set for 2021. PMID:25960271

    Full Text Available Abstract Background The sulfide-rich Frasassi caves in central Italy contain a rare example of a freshwater ecosystem supported entirely by chemoautotrophy. Niphargus ictus, the sole amphipod species previously reported from this locality, was recently shown to host the first known case of a freshwater chemoautotrophic symbiosis. Since the habitat of N. ictus is highly fragmented and is comprised of streams and lakes with various sulfide concentrations, we conducted a detailed study to examine the potential genetic diversity of this species within Frasassi. Results By sequencing one nuclear (ITS and two mitochondrial (COI and 12S regions, we show that four partially sympatric Niphargus clades are present in Frasassi. Morphological and behavioral data obtained for three of these clades are perfectly congruent with this molecular delineation and make it possible to distinguish them in the field. Phylogenetic analyses of 28S ribosomal DNA sequences reveal that, among the four clades, only two are closely related to each other. Moreover, these four clades occupy distinct niches that seem to be related to the chemical properties and flow regimes of the various water bodies within Frasassi. Conclusions Our results suggest that four distinct Niphargus species are present in Frasassi and that they originated from three or four independent invasions of the cave system. At least two among the four species harbor Thiothrix epibionts, which paves the way for further studies of the specificity and evolutionary history of this symbiosis.

    Neanderthals have been traditionally considered at the top of the food chain with a diet mostly consisting of animal proteins. New findings challenged this view and suggested that Neanderthals living in areas with more favourable climatic conditions exploited various food sources, including plant materials. In this study, the attention is focused on dental macrowear of Neanderthals from Central Italy, whose diet has been largely unexplored. Three-dimensional digital models of teeth have been examined through occlusal fingerprint analysis (OFA), a method used to understand how wear facets are formed. The results show a close similarity between the specimens of Saccopastore 1 and 2, with a wear pattern that indicates the use of diverse sources of food, but with a predominance of animal proteins. On the other hand, the specimens of Guattari 2 and 3 display a slightly different dental wear from each other, which probably reflects the chronological sequence of the Guattari Cave. It appears that at the end of the marine isotope stage (MIS)5 the occupants of this cave consumed marginally more plant foods, while during MIS 3 they relied more on animal proteins. Finally, a close look at the Saccopastore maxillary molars reveals the presence of a distinct type of wear that has been previously described in some Neanderthals and early Homo sapiens from Near East, and it provides additional information about the culture and lifestyle of these Pleistocene human populations.

    Full Text Available This paper describes the chemical and isotope features of water and dissolved gases from lake Paterno (max. depth 54 m, a sinkhole located in the NE sector of the S. Vittorino plain (Rieti, Central Italy, where evidences of past and present hydrothermal activity exists. In winter (February 2011 lake Paterno waters were almost completely mixed, whereas in summer time (July 2011 thermal and chemical stratifications established. During the stratification period, water and dissolved gas chemistry along the vertical water column were mainly controlled by biological processes, such as methanogenesis, sulfate-reduction, calcite precipitation, denitrification, and NH4 and H2 production. Reducing conditions at the interface between the bottom sediments and the anoxic waters are responsible for the relatively high concentrations of dissolved iron (Fe and manganese (Mn, likely present in their reduced oxidation state. Minerogenic and biogenic products were recognized at the lake bottom even during the winter sampling. At relatively shallow depth the distribution of CH4 and CO2 was controlled by methanotrophic bacteria and photosynthesis, respectively. The carbon isotope signature of CO2 indicates a significant contribution of deep-originated inorganic CO2 that is related to the hydrothermal system feeding the CO2-rich mineralized springs discharging in the surrounding areas of lake Paterno. The seasonal lake stratification likely controls the vertical and horizontal distribution of fish populations in the different periods of the year.

  20. Rainfall and land use empirically coupled to forecast landslides in the Esino river basin, central Italy

    2015-06-01

    A coupled empirical approach to highlight relationships between rainfall, vegetation segmentation, and landslide occurrence is discussed. To reveal such links, two important rainfall events, which occurred over the Esino river basin in central Italy in November 2013 and May 2014, were analysed. The correlation between rainfall and landslides was evaluated by applying an intensity-duration (ID) threshold method, whereas the correlation between vegetation segmentation and landslides was investigated using morphological spatial pattern analysis (MSPA). This coupled approach represents an attempt to find both timing and location of landslide occurrence through an empirical (black box) analysis. Results showed: (i) the ID minimum threshold proposed in a previous study (Gioia et al., 2015) to be verified as an effective equation to assess the rainfall conditions likely to trigger landslides in the study area ("when"), and (ii) the core areas and the fragmented vegetation structures defined by the MSPA to be the most affected by slope failures ("where"). These encouraging findings prompt additional testing and the application of such a coupled empirical approach so that it is possible to achieve an integrated basis for landslide forecasting.

  1. Comparing multisource harmonized forest types mapping: a case study from central Italy

    Full Text Available The availability of common standardized geospatial information on composition, structure and distribution of forests is essential to support environmental actions, sustainable forest management and planning policies. Forest types maps are suitable tools for supporting both silvicultural and forest planning choices from local to global scale levels. For this reason local authorities may develop forest types maps independently, in which case a standardized/harmonized framework for their comparison and aggregation is essential. At the same time local forest types maps may not be directly related to pan-European forest resources assessments and classification systems. This paper presents results of the harmonization of four forest types maps available for central Italy. The process is based on a bottom-up approach aimed at maintaining the most detailed common nomenclature system across the different Regions. The final results, in terms of forest types area, are compared with several independent sources of information: (i two forest maps, one developed at national level on the basis of the Corine Land Cover 2006, and one for high resolution forest / non forest classification developed at pan-European level; and (ii two sample based inventories: the Italian National Forest Inventory (INFC and the Italian Land Use Inventory (IUTI. The results show that the proposed bottom- up harmonization approach is a suitable tool to guarantee the integrity and homogeneity of local forest types nomenclature systems, and to integrate such local data with European standards.

    Differences in bark and wood content in woody biomass directly affect its quality and economic value as an energy source. In order to estimate the quality of biomass before harvesting, an allometric regression of bark percentage of total aboveground biomass and DHB (diameter at 1.30 m height) was developed in a 2-year poplar short-rotation coppice system in Central Italy. Firstly, a relationship between mean diameter and bark content percentage was established in 1 cm-wide sections belonging to all diametric classes. The model of best fit for these stem cylindrical sections was an equation y=ax{sup -b}. Following this, sample stems (of which we measured DHB) were collected and divided into sections belonging to a diameter class. Fresh and dry matter were determined for each class. Using the first equation, bark content was calculated separately for all classes. Thereafter, a second equation between bark content in the whole stem and DHB was developed. The best fitting equation for the whole stem was y=cx{sup -d}. Bark content in the whole stem ranged from 33.9-31.4% in large-sized DHB stems to 15.1-12.5% in smallest stems, depending on their moisture content. Bark content decreased rapidly in the small diametric classes until DHB reached 4 cm. Thereafter, the ratio of reduction of bark percentage dropped. (author)

    The increasing focus on infections in domestic cats ( Felis catus ) has raised questions about lungworm distribution in wild hosts. To enhance knowledge of the occurrence of lungworms in enzootic regions of central Italy, we examined the carcasses of 16 European wildcats ( Felis silvestris silvestris). Adult nematodes, feces, respiratory flushings, and pulmonary tissues were collected at necropsy and then microscopically and genetically analyzed. Fourteen wildcats had single or mixed lungworm species. Aelurostrongylus abstrusus was the most common parasite retrieved, followed by Troglostrongylus brevior. In addition, three specimens of Angiostrongylus chabaudi were found in the pulmonary arteries of one wildcat. Histologically, the most common lesions were a mild-to-severe chronic catarrhal bronchitis and a chronic interstitial pneumonia with smooth muscle hypertrophy, associated with T. brevior and A. abstrusus , respectively. These results demonstrate that the European wildcats may harbor several species of lungworms that may impair their health and welfare. Also, F. s. silvestris is a potential reservoir for respiratory nematodes in domestic cats. PMID:26967134

    A revised seismic catalogue (1994-2007) for the central-eastern Alps (N Italy) is presented. 396 earthquake relocations, for local magnitudes in the 1.2-5.3 range, are performed using a 3D crustal velocity structure and probabilistic locations. The location procedure is validated by computing a set of 41 quarry shot solutions and all the results, both about shots and seismic events, are compared with those obtained using the routine location procedure. Results are shown for five contiguous seismotectonic domains, as supported by geological and geophysical evidence (e.g., fault systems, crustal tomography, focal mechanisms types). Earthquake hypocentres are mostly located in the upper crust (0-15 km of depth), in good agreement with thermo-rheological models about the brittle-ductile transitions (8-9 km of depth) and total crustal strengths (1.0-2.0 TN m- 1). Epicentres are clustered and/or aligned along present-day active geological structures. The proposed seismotectonic model shows dominant compression along the Giudicarie and Belluno-Bassano-Montello thrusts, with strain partitioning along the dominant right-lateral strike-slip faults of the Schio-Vicenza domain. The present-day deformation of the Southern Alps and the internal Alpine chain is compatible with Adria indentation and the related crustal stress distribution.

    Full Text Available The farm can be considered as the decision unit in the agricultural land management, therefore it is the most suitable scale to analyse the farmers’ strategies of production. In this paper we describe the results of a comparison between two enquiries carried out in 1992-93 and 2009-10 on more than 30 farms, corresponding to about 1500 ha of utilised agricultural area (UAA, within the boundaries of the San Rossore, Migliarino, Massaciuccoli Regional Park (central-western Italy. We calculate a set of agri-environmental indicators both at territory and farm scale in order to point out the changes occurred over almost twenty years in the farms’ structure, management and production features. The results showed that the major differences were related to fertilisers management (clearly decreasing, to the reduction of some crop types (industrial crops and to the strong decrease of the gross marketable production. Furthermore, apparently stable indicators, such as the utilised agricultural area and the farm tractors’ power, were actually the result of the compensation of contrasting trends. Farmers’ behaviours were substantially homogeneous within the same typology of farm, highlighting common evolution strategies. The desirability of the occurred changes was also evaluated, underlining the improvement of environmental sustainability of the current cropping systems and a greater social acceptability of agricultural activities, while the evaluation from the farmers’ point of view was less satisfactory.

    Full Text Available Abstract The present paper summarizes the results of 3 years of observation made at six month intervals for six months at a time (18 field surveys in a man-made cave in Northern Latium (Central Italy from April 1992 to April 1995. Its aim is to analyze the main structural and dynamic features of a bat community which hibernates at the shelter. Rhinolophus ferrumequinum and especially Rhinolophus euryale are the most abundant species. Population dynamics of both species as well as that of Rhinoluphus hipposideros show higher levels of abundance between December and February of each semester. In mid-winter, large and sometimes mixed aggregations of Rhinolophus ferrumequinum and Rhinolophus euryale in deep hypothermia occur. A small number of Rhinolophus hipposideros, mainly adult males, was observed. The paper compares the structure of this community to the structure of another community of the same district which has been previously analyzed, in which Vespertilionidae, especially Miniopterus schreibersi, are much more abundant. Despite the difference in species composition, body size was found to be a significant and common feature (as highlighted by forearm length, of the dominant species in both communities, Rhinolophus euryale and Miniopterus schreibersi respectively.

Water content in the soil was measured using a Theta Probe Soil Moisture sensor (ML2x by Delta-T-Devices with a direct read-out device that provides soil moisture estimates as percent volume. The correlation between the experimental values obtained by the gravimetricmethod and thevalues directly measured by Theta Probe was found significant. Soil moisture at 100 cm depth indicates soil water as permanently available for plants through the year except during exceptionally dry summer periods. Therefore, oaks experienced no water deficiency with normal rainfall rates, possibly suffering root asphyxia during rainy years. Results are collected in fenced areas, sheltered by the action of the local fauna.

    The construction of roads is currently well spread in many parts of our world and impacts strongly on wildlife distribution. Some bird species avoid, while other prefer to be in the vicinity of these human structures. However, studies on roads effects on birds, in terms of strength or direction of these effects, are scarce. Therefore, in a study carried out in Central Italy we tested the responses of different bird species to roads at a local spatial scale, using generalized linear models (GLM). Analysis were conducted on a large dataset (more than 1400 sampled sites, mainly on rural environments). Both positive and negative effects of roads on birds were found for bird species of close or semi-close environments, while the negative effects of roads were negligible for bird species of open and semi-open environments. This fact suggest that roads can be a source of "functional heterogeneity" on semi-open environments, providing marginal habitats, hedgerows and residual vegetation typical of roadsides, offering breeding and feeding habitat for some bird species. The proposed methodology provide a useful explorative tool, in order to develop conservation policies to preserve the biodiversity, mainly in rural landscapes. The outputs of GLM can be used as inputs in ecological planning: direction and strength of the effects of roads on bird species are adequate to estimate the response of bird community, up front to the presence of new structures, or identifying which of them should be mitigated to reduce negative effects on the biodiversity.

  9. Magmatic control along a strike-slip volcanic arc: The central Aeolian arc (Italy)

    The regional stress field in volcanic areas may be overprinted by that produced by magmatic activity, promoting volcanism and faulting. In particular, in strike-slip settings, the definition of the relationships between the regional stress field and magmatic activity remains elusive. To better understand these relationships, we collected stratigraphic, volcanic and structural field data along the strike-slip Central Aeolian arc (Italy): here the islands of Lipari and Vulcano separate the extensional portion of the arc (to the east) from the contractional one (to the west). We collected >500 measurements of faults, extension fractures and dikes at 40 sites. Most structures are NNE-SSW to NNW-SSE oriented, eastward dipping, and show almost pure dip-slip motion; consistent with an E-W extension direction, with minor dextral and sinistral shear. Our data highlight six eruptive periods during the last 55 ka, which allow considering both islands as a single magmatic system, in which tectonic and magmatic activity steadily migrated eastward and currently focus on a 10 km long x 2 km wide active segment. Faulting appears to mostly occur in temporal and spatial relation with magmatic events, supporting that most of the observable deformation derives from transient magmatic activity (shorter-term, days to months), rather than from steady longer-term regional tectonics (102-104 years). More in general, the Central Aeolian case shows how magmatic activity may affect the structure and evolution of volcanic arcs, overprinting any strike-slip motion with magma-induced extension at the surface.

    2004-06-01

    Full Text Available The 346 A.D. earthquake is known through sparse historical sources. It is mentioned by Hyeronimus as felt in Rome and responsible for damage in the ancient Campania Province. Four epigraphs report the earthquake as the cause for the restorations of buildings at Aesernia-Isernia, Allifae-Alife, Telesia-Telese and Saepinum-Sepino. On this basis, an area possibly struck by the earthquake was already defined in the literature. Another seventeen epigraphs mentioning restoration or re-building of edifices in localities of central-southern Italy (without explicitly referring to the earthquake as the cause of the damage are possibly related to the earthquake effects. We tried to enhance our knowledge on the 346 earthquake through archaeoseismological analyses. The investigation has benefited from specific fieldwork during archaeological excavations and a critical review of the available archaeological literature. However, a correct archaeoseismological interpretation is hindered by the occurrence of two earthquakes (346 and 375 A.D. in a short time span and in adjacent areas (whose effects may be archaeo-chronologically undistinguishable and the not always univocal evidence of the seismic origin of the detected collapses or restoration of structures. For this reason we propose a representation of the 346 A.D. effects through two extreme pictures: 1 the localities for which conclusive data on the earthquake effects are available and 2 the data of point 1 plus the localities for which archaeoseismological data consistent with the earthquake are available. The latter view defines an area of possible damage related to the 346 event larger than that previously known. In particular, the earthquake damage may result from a seismic sequence similar to that, which struck a part of the central and the southern Apennines in 1456, or from an event comparable to that which occurred in 1805, responsible for widespread damage in the northern sector of the southern

    Results show that the year-to-year quality variation of wines produced in North and Central Italy depends on the large-scale climate variability, and that the wine quality improvement in the last four decades is partially due to an increase of temperature and to a decrease of precipitation in West and Central Mediterranean Europe (WME; CME). In addition, wine quality is positively correlated with air temperature throughout the entire active period of the grapevine, weakly negatively correlated with precipitation in spring, and well negatively correlated in summer and fall. The month-to-month composites of the NAO anomaly show that, in years of good quality wine, this anomaly is negative in late spring, oscillates around zero in summer, and is positive in early fall; while, in years of bad quality wine, it is positive in late spring and summer, and negative in early fall, i.e. its polarity has an opposite sign in spring and fall in good versus bad years. The composite seasonal maps show that good wines are produced when the spring jet stream over the Atlantic diverts most of the weather perturbations towards North Europe, still providing a sufficient amount of rainwater to CME; when summer warming induced by southerly winds is balanced by the cooling induced by westerly winds; and when a positive geopotential anomaly over WME shelters CME from fall Atlantic storms. Bad quality wines are produced when the jet stream favors the intrusion of the Atlantic weather perturbations into the Mediterranean. Results suggest that atmospheric pattern persistencies can be used as precursors for wine quality forecast. PMID:23152193

    Full Text Available Magnetotelluric data were collected at Collemeluccio (41.72°N, 14.37°E in Central Italy from summer 1991 to spring 1998. Analyzed by means of tensor decomposition on the geoelectric potential and robust estimation on the geomagnetic field, this set of data allowed the investigation of the electric properties at different time-periods. The variation of some indicators, related to the phenomenon of electromagnetic induction, is presented here in its time evolution and compared to local and regional seismic activity. Tectonomagnetic field observations from absolute magnetic field level in Central Italy were also made on data simultaneously recorded at four magnetometer stations, using L'Aquila Geomagnetic Observatory as a reference for differentiation. Recent results gathered from a system of two VLF search coil wide-band antennas, installed in the L'Aquila Observatory, are also discussed in relation to local seismic activity.

  17. Sustainability of sunflower cultivation for biodiesel production in central Italy according to the Renewable Energy Directive methodology

    2014-02-01

    Full Text Available The use of renewable energies as alternative to fossil fuels has value from different points of view and has effects at environmental, social and economic level. These aspects are often connected to each other and together define the overall sustainability of bioenergy. At European level, the Directive 2009/28/EC gives the basic criteria for the estimation of sustainability of biofuels and indicates a minimum threshold of 35% of greenhouse gas saving for a biofuel in order to be considered sustainable. The Directive gives the possibility to identify standard regional values for the cultivation steps that could be utilized for the certification. This paper aims to give a contribution to the definition of these values considering the RED methodology applied to the sunflower cropped in central Italy which is characterized by a hilly landscape and not-irrigated crops. To determine input and output of sunflower cultivation in the central Italy, the results of PROBIO project, carried out by the Authors, were used. The sustainability of biodiesel produced from sunflower grown in central Italy is variable and depends on the nitrogen input and seasonal climatic conditions that affect the yields. The greenhouse gases savings of the Italian chain is 40% in average, greater than the required 35% and would be possible to assign this value as standard to the biofuel chain biodiesel from sunflower cultivated in central Italy. Using an averaged regional standard value guards against the possibility of considering unsustainable harvesting in unfavourable years and seeing it overestimated in the favourable ones.

    The ancient Etruscan town of Norchia (Central Italy, 80 km North of Rome) is situated on a long volcanic plateau surrounded by steep slopes, at the confluence of rivers Pile and Acqua Alta into the river Biedano. It has been constructed along the ancient Via Clodia, a short-range route intended for commercial traffic between Rome and the colonies in Etruscan lands. The flourishing of the town, evidenced by the beautiful necropolis, is placed between the end of the fourth and half of the second century BC. With its necropolis Norchia is the most significant example of funerary architecture rock Hellenistic period (IV-II century BC.). Its rock-cut tombs, are among the most important archaeological sites of Etruscan civilisation. They are an important and rare example of rock architecture and one of the few preserved in Italy. Also, the necropolis, with an extension of more than 100 hectares, is composed of rock-cut tombs of various types (façade, half-cube, false-cube and temple type) and dimensions (4-10 m in height), exhibiting a remarkable similarity with Asian tombs. From geological point of view, the area is exhibiting the overly of rigid volcanic products from both Vico and Volsini volcanic apparatus; as a bedrock, a plastic clay formation is positioned. The rock-cut tombs were excavated on two main volcanic levels, following the natural profile of tuff outcrops. The tombs located in the upper part of the necropolis have been excavated in a Red Tuff from Vico volcanic district, while those in lower level are dug in a grey tuff (Nenfro) from Vulsini volcanic apparatus. Recent investigations revealed the presence of many threats affecting the conservation of the site, that are including: surface rock weathering, water percolation and infiltration, surface vegetation and biological colonisation, instability and collapse of the cliff. The purpose of this study is mainly focused to verify whether the geological, geomorphological and geomechanical processes that

    Abstract An attempt was made to evaluate the diversity and distribution of cave bats of Latium (Central Italy). Data about twelve species were examined and their frequency have been determined. Only Rhinolophus ferrumequinum and R. hipposideros are really frequent: the other species are more or less localized. The average number of species (2,63) has a great importance for future contro1 of cave bat populations. Similarit...

    Simple exposure to Western goods may not be a sufficient explanation of why isolated village communities increase their participation in external market economies. The degree of market participation by four native villages in central Brazil is related to the difficulty of making a living from slash-and-burn subsistence agriculture as measured by the ratio of labor input to food output.

Moreover the sub-basins represent the surface evidence of traits belonging to the Norcia seismogenic structure, which have repeatedly caused earthquakes in the past, thus determining similar geological, structural and morphostructural features within the wider Norcia area, without causing the whole structure to rupture. The size of these sub-basins and, thus, the size of the relevant seismogenic segments, allows to calculate a maximum magnitude for the three sub-basins and for the seismogenic area as a whole.

  6. Modelling the radionuclide balance in some water bodies of central Italy

    International Nuclear Information System (INIS)

    This article illustrates the quantitative analysis of the radionuclide behaviour in some lakes of central Italy and in their outlets. The migration rates and the effective transport velocities of the radionuclides to sediment were estimated. In the examined lakes (Albano, Bolsena, Bracciano, Nemi and Vico), the concentrations of 90Sr and 137Cs show a marked exponential time decay due to the radioactive decay, the radionuclide removal by the outlets and the radionuclide migration from water to bottom sediments. It was estimated that the 137Cs average migration rate to sediment is 1.2 x 10-9 s-1 corresponding to an effective migration velocity of 5.8 x 10-8m s-1. The radionuclide concentrations in watercourses Marta (outlet of Lake Bolsena) and Rio Vicano (outlet of Lake Vico) were fitted by exponential (decay) functions of the distance from the lake. The 'half-distance' of the above process ('half-distance' = the distance for the radionuclide concentration reduces to one half) is 12.6 km and 3.9 km for 137Cs in river Marta and Rio Vicano, respectively. The half-distances for 90Sr in the above watercourses are, respectively, 30 km and 5.8 km. The half-distances were quantitatively related to the effects of water dilution and to the radionuclide contribution from catchment. The analysed data offered the opportunity of calculating that the 90Sr contribution from catchment to the examined watercourses is in the order of 10-3-10-4 Bq s-1 m-1 (radionuclide flowing per second and per metre of river).

    Full Text Available Household energy consumption has been increasing in the last decades; the residential sector is responsible for about 40% of the total final energy use in Europe. Energy efficiency measures can both reduce energy needs of buildings and energy-related CO2 emissions. For this reason, in recent years, the European Union has been making efforts to enhance energy saving in buildings by introducing various policies and strategies; in this context, a common methodology was developed to assess and to certify energy performance of buildings. The positive effects obtained by energy efficiency measures need to be verified, but measuring and monitoring building energy performance is time consuming and financially demanding. Alternatively, energy efficiency can also be evaluated by specific indicators based on energy consumption. In this work, a methodology to investigate the level of energy efficiency reached in the Umbria Region (Central Italy is described, based on data collected by energy certificates. In fact, energy certificates, which are the outcomes of simulation models, represent a useful and available tool to collect data related to the energy use of dwellings. A database of building energy performance was developed, in which about 6500 energy certificates of residential buildings supplied by Umbria region were inserted. On the basis of this data collection, average energy and CO2 indicators related to the building heritage in Umbria were estimated and compared to national and international indicators derived from official sources. Results showed that the adopted methodology in this work can be an alternative method for the evaluation of energy indicators; in fact, the ones calculated considering simulation data were similar to the ones reported in national and international sources. This allowed to validate the adopted methodology and the efficiency of European policies.

  8. Concentration and characteristics of uranium isotopes in water collected in central Italy and Balkan regions

    International Nuclear Information System (INIS)

    Full text: Uranium is a naturally occurring, ubiquitous heavy metal found in the environment in various chemical forms in all soils, rocks, seas and oceans. It is also present in air, food and drinking water. Due to its widespread existence in nature, uranium isotopes (238U, 234U and 235U) have become one of the most important source of natural radioactivity and make a significant contribution to external and internal dose to population. Uranium isotopes enter the human body mainly through ingestion, and by inhalation to a considerably smaller degree. Hence the internal radiation exposure for members of the public can be evaluated through the intake of the radionuclides from both food and water. Pietrzak-Flis et al., have investigated the uranium intake fractions of the different pathways, and concluded that the uranium intake from water by man is the most important pathway which contributes the largest fraction (75.1%-76.9%) of uranium intake. For the purpose of estimating the radiological impact of uranium isotopes in water to the residents, some natural water samples were collected in central Italy and Balkan Regions and analysed in the laboratory of Italian Environmental Protection Agency and Technical Services (APAT). The activity concentrations of 238U, 234U and 235U were obtained. The radioanalytical procedure used for determination of uranium isotopes in water mainly includes steps of uranium pre-concentration, mineralization, separation by a Microthene- TOPO column, electrodeposition and measurement by alpha-spectrometry. Based on the obtained activity concentrations of uranium isotopes in drinking water, annual consumption rate of the water, and the dose conversion factor per unit intake given by the International Commission on Radiological Protection, the annual effective dose resulting from 1-year ingestion for the adult population was calculated.

    Full Text Available A synthesis is made of biological data collected in the last three decades on five volcanic lakes in Central Italy with the aim of evaluating their environmental status by means of biological parameters related to zooplankton, littoral and profundal zoobenthos frequently used to detect water quality changes in lakes. A number of bioindicators and bioindices were selected for this purpose, as far as possible following an integrated approach using information drawn from physical and chemical variables. Our results allowed the lakes to be classified according to their biological quality level, which proved to be in good agreement with physical and chemical diagnoses. Lake Bracciano exhibited the best environmental quality, due to the presence of a ring waste water collecting system, to its large size and depth, and to its strong hydrodynamism. Lake Martignano followed, with some symptoms of stress in the hypolimnion due to a marked summer deoxygenation. Oxygen depletion in the profundal characterized also Lake Vico, which showed a mesotrophic condition in the sixties, and 20 years later now shows clear signs of increased trophy (meso-eutrophy. Lake Albano seemed meso-eutrophic with total absence of fauna below a depth of 120 m due to a meromictic status. Finally Lake Nemi, exposed to domestic wastes in the 70s, suffered a heavy eutrophication with dramatic algal blooms and fish kills. Following the diversion of discharges that occurred in the early 90s, today this lake is characterized by the partial improvement of many ecological features. The need for integration between physical and chemical analyses and biological data in order to obtain a reliable evaluation of lake environmental quality is stressed, especially as far as routine implementation in managing and recovery procedures is concerned.

    The adoption of precision agriculture in viticulture requires the knowledge of the spatial and temporal variability of available soil water. A three-years trial was carried out in Chianti (central Italy) on Sangiovese vine to test the prediction capacity of selected hydropedological models for two soil series cultivated with grape and for delineating hydrological functional units within two vineyards. The soils of the vineyards differentiated in structure, porosity and related hydropedological characteristics, as well as in salinity. Soils were mapped with a geophysical survey and six plots were selected in different morphological positions: summit, backslope and footslope. Water content, redox processes and temperature were monitored, and yield, phenological phases, and chemical analysis of grapes were determined. The isotopic ratio δ13C was measured in the wine ethanol upon harvesting to evaluate the degree of water stress suffered by vines. The grapes in each plot were collected for wine making in small barrels. The wines obtained were analysed and submitted to a blind organoleptic testing. The results demonstrated that the tested hydropedological models can be used for the prevision of the moisture status of soils cultivated with grape during summertime in Mediterranean climate. As foreseen by the models, the amount of mean daily transpirable soil water differed considerably between the vineyards and increased significantly along the three positions on slope in both vineyards and in every year, even during the very dry 2006. However, both the response of Sangiovese to water stress and the quality of wine were influenced by the interaction between transpirable water and salinity. The installation of IRIS tubes allowed confirmation of the occurrence of redox processes, although discoloration was influenced more by soil temperature, rather than by moisture. The map produced by once only geophysical survey mirrored only partially the seasonal hydropedology of

    PATRIZIA MAIORANO

    2006-07-01

    Full Text Available Calcareous nannofossil assemblages have been investigated by means of quantitative analyses in three Oligocene pelagic sections located in the Umbria-Marche Apennines (Central Italy. The studied sections mainly consist of marly limestones and marls belonging to the Scaglia Cinerea Formation, and include the interval between NP23 and NP25 representing a time interval of about 3.5 Ma. Biostratigraphic resolution is extremely low and only two standard bioevents are known, which are the FO of Sphenolithus ciperoensis and the LO of Sphenolithus distentus. The distribution patterns of poorly known or recently described calcareous nannofossils provided a valuable tool for improving the current biostratigraphic framework. The studied interval is characterized by significant changes in the calcareous nannofossil assemblages and by several extinction events. The last occurrence (LO and/or the last common occurrence (LCO here proposed are: the LO of Sphenolithus akropodus, the LO of Reticulofenestra circus, the LCO of Helicosphaera ethologa, the LCO of Helicosphaera compactathe LO of Discoaster tanii nodifer. The reversal in abundance between Sphenolithus predistentus and S. distentus provided an additional biostratigraphic constraint at the NP23-NP24 transition. In addition biometric criteria enabled the recognition of the first common occurrence (FCO of Cyclicargolithus abisectus > 12 mm as potential bioevent within NP24. The quantitative distribution of Sphenolithus distentus suggests to rely on the LCO of the species rather than on the LO, for the identification of NP24-NP25 boundary. The identified bioevents is a first step towards the improvement of the present Mediterranean biostratigraphic framework of the Oligocene geological record. A preliminary correlation of the bioevents to the Geomagnetic Polarity Time Scale is presented.

  13. Transient magmatic control in a tectonic domain: the central Aeolian volcanic arc (South Italy)

    The background stress field in volcanic areas may be overprinted by that produced by transient magmatic intrusions, generating local faulting. These events are rarely monitored and thus not fully understood, generating debate about the role of magma and tectonics in any geodynamic setting. Here we carried out a field structural analysis on the NNW-SSE strike-slip system of the central Aeolian Arc, Italy (Lipari and Vulcano islands) with ages constrained by stratigraphy to better capture the tectonic and magmatic evolution at the local and regional scales. We consider both islands as a single magmatic system and define 5 principal stratigraphic units based on magmatic and tectonic activity. We collected >500 measurements of faults, extension fractures and dikes at 40 sites, mostly NNE-SSW to NNW-SSE oriented with a dominant NS orientation. These structures are governed quasi exclusively by pure dip-slip motion, consistent with an E-W extension direction, with minor dextral and sinistral slip, the latter being mostly related to old deposits (>50 ka). We further reconstructed the evolution of the Vulcano-Lipari system during the last ~20 ka and find that it consists of an overall half-graben-like structure, with faults with predominant eastward dips. Field evidence suggests that faulting occurs often in temporal and spatial relation with magmatic events, suggesting that most of the observable deformation derived from transient magmatic activity, rather than from steady regional tectonics. To explain the dominant magmatic and episodic extension in a tectonic dominant domain, we propose a model where the regional N-S trending maximum horizontal stress, responsible for strike-slip activity, locally rotates to vertical in response to transient pressurization of the magmatic system and magma rise below Lipari and Vulcano. This has possibly generated the propagation of N-S trending dikes in the past 1 ka along a 10 km long by 1 km wide crustal corridor, with important

  14. Tephra ring interpretation in light of evolving maar-diatreme concepts: Stracciacappa maar (central Italy)

    Maar-diatreme volcanoes in their simplest form are thought to result primarily from discrete, subsurface phreatomagmatic explosions. Tephra ring deposits around maar craters are commonly interpreted in terms of a framework wherein explosions begin at shallow levels and migrate downward, ejecting progressively deeper-seated lithic clasts that contribute to the tephra rings. Additionally, variations in grain size of the deposits are sometimes inferred to record different degrees of fragmentation, which are in turn related to variations in magma-water ratios at the explosion sites. Recent detailed studies of diatremes and of maar tephra rings suggest a different conceptual model wherein explosions can happen at various vertical and lateral locations within a diatreme during its eruptive lifetime, rather than being limited to simple downward migration. Experiments, numerical modeling, and field data indicate that most explosions deeper than about 200-250 m will not vent to the surface, but instead contribute to mixing within the diatremes. Arrival of deep-seated lithics at the surface is related to this mixing process. Experiments also indicate that explosion phenomena can result in a range of emplacement mechanisms and grain sizes in tephra rings, even in the absence of variations in explosion mechanisms (fragmentation efficiency). Here we document the tephra ring of Stracciacappa maar (central Italy), and interpret its eruption and emplacement history in terms of evolving conceptual models along with a comparison to more traditional interpretations. Because most elements of both conceptual models are viable, the work points to an important need to develop criteria to distinguish between the various inferred mechanisms.

    The aim of this study is to analyze the subjective perception of risks for rural workers in Abruzzo, an area of central Italy. A group of 273 workers were asked to fill in a questionnaire which included, apart from general information, questions relative to six different types of risks normally found in the field of agriculture. The types of risks considered were: falling from a height, manually moving loads, overturning/accident whilst driving an agricultural tractor, noise and vibration, use of pesticides, the risk of being cut/injured. The workers were requested to assess, on a scale of 1 to 3, both the probability of an accident taking place and the consequent damage which could result from each of the risks considered. The assessment of the risks provided by the workers was related to the objective assessment of the risks carried out by the study group, also on the basis of objective data provided by INAIL (Italian insurance company) indexes, to highlight the eventual under/over estimations of risk. Furthermore, the possible correlation was evaluated between having received specific training regarding work safety and the workers perception of the risk. The results showed that approximately 11 percent of the workers do not consider their job as being dangerous; the risk perceived by the workers is higher for accidents that cause an immediate injury compared to those which cause professional illnesses, except the risk deriving from noise/vibrations. A direct correlation was found between the job as being dangerous and having attended courses on accident prevention. PMID:23034263

    2015-12-01

    Full Text Available Black pine has been used often in central and southern Italy to reforest mountainous areas depleted by the intensive use of natural resources. The main purpose of establishing pine forests in Italy was to protect the soil from excessive erosion, and also to facilitate the natural succession toward mixed forests with deciduous species. The most common silvicultural treatments in Europe currently aim at maximizing the stability of the stands and facilitating the transition from pure to mixed stands comprising a larger component of native tree species. In this work, we investigated the relationships between the living whorls number and four indexes of individual tree stability: the slenderness ratio, the crown depth, the crown projection, and an eccentricity index of the canopy. The data set used was composed of 1098 trees from ten black pine plantations located in central Italy. Our results demonstrate that the living whorls number can be handily used to predict the slenderness ratio with an error of 18%. A non-parametric model based on a reduced number of field measures was obtained as a support for thinning operations aimed at improving single tree stability.

  17. Why is the central area of the Alburni Mts in southern Italy so full of caves?

    The Alburni Mts represent one of the most important karst area of southern Italy, with about 250 registered caves. Located in the southern Apennines, they constitute an impressive carbonate massif within the Mesozoic-Cenozoic Campania-Lucania platform. The study area is located inside the National Park of Cilento, Vallo di Diano and Alburni, and is bounded by two major rivers: the Calore and Tanagro rivers. This area has been repeatedly affected during Pleistocene by the activity of a regional, partly blind, NW-SE-striking fault system responsible for several huge earthquakes. The massif is limited to the north by an important normal fault zone (Alburni Line), whereas towards the E-SE it is bounded by a complex fault system linking the Alburni Mts to the Maddalena Mts across the Auletta basin and the Vallo di Diano valley. The entire massif is structured by NW-SE trending transtensional faults delimiting half-graben basins, and offset also by NE-SW trending faults. In particular, structural and geomorphological data have shown that the central area of the calcareous ridge is characterized by a relative structural low rhombic-shaped in planimetric view. Approximately 180 karst caves of the known 250, including some of the most significant from a speleological viewpoint, are located in this area. Is this simply due to repeated exploration activity in the last 25 years in this specific sector or might it be related to geological matter? New morphometric and structural data suggest that a relevant transversal structure, consisting of a complex NE-SW fault system, responsible for the genesis of the downthrown area in the central sector of the flat-topped ridge, was able to create the tectonic framework for the development of a great number of karst caves which present peculiar features and hydrological behaviour due to such structural controls. In this contribution we present and discuss these data, aimed at contributing to increase the knowledge on an area of sure

    Pseudomonas avellanae (Pav) has been reported as the causal agent of bacterial decline and bacterial canker of hazelnut in Italy and Greece, respectively. Both hazelnut diseases were reported to be similar in terms of symptoms, severity and persistence. In this study, we found that both symptomatic and asymptomatic trees in the field were colonized by Pav. Multilocus Sequence Typing (MLST) analysis showed that Pav strains isolated during this study in Italy belong to the P. syringae phylogroup 1 and they are closely related to Pav strains previously isolated in Greece from hazelnut bacterial canker. On the other hand, strains isolated in earlier studies from hazelnut decline in Italy belong to both phylogroup 1 and 2 of P. syringae. Both phylogroup 1 strains of P. syringae from Greece and Italy are different than strains isolated in this study in terms of their capacity to excrete fluorescent pigments on different media. Despite the same plant genotype and cropping practices adopted, the incidence of hazelnut decline ranged from nearly 0 to 91% across our study sites. No disease developed on plants inoculated with Pav through wounding while leaf scar inoculations produced only mild disease symptoms. Based on our results and the previously reported correlation between pedo-climatic conditions and hazelnut decline, we conclude that hazelnut decline in central Italy could be incited by a combination of predisposing (adverse pedo-climatic conditions) and contributing factors (Pav). Because this is a true decline different from "bacterial canker" described in Greece, we refer to it as hazelnut decline (HD). PMID:26840951

Based on our results and the previously reported correlation between pedo-climatic conditions and hazelnut decline, we conclude that hazelnut decline in central Italy could be incited by a combination of predisposing (adverse pedo-climatic conditions and contributing factors (Pav. Because this is a true decline different from "bacterial canker" described in Greece, we refer to it as hazelnut decline (HD.

    We propose, as a poster, the experience in meteorology and climatology education that has been acquired by OSMER ARPA FVG (the local regional meteorological observatory of the Friuli Venezia Giulia region, NE Italy). It was aimed at spreading a better culture in meteorology, climatology and environmental-friendly behaviour through general and specific knowledge. In the last 10 years many public and private schools were involved into a net of knowledge through the work of a pool of teachers, proposing a new way of understanding meteorology studies. The first step was to catch the attention of students on the observation tools, in particular on the meteorological ground-based instruments: a wooden-made box has been built to host meteorological instruments. The second step was to teach the main methods to collect correct observations and to simply analyze meteorological data. In a following step we propose to a small group of highschool students to carry on their knowledge in meteorology and climatology for younger students through the exhibit of 20 kits containing meteorological instruments and various experiments in environmental sector (energy saving, greenhouse effect, etc), according to the method of peer-education, during special meetings with the participation of hundreds young students. The last step has been the interpretation of the new knowledge acquired by the young students through the realization of banners, videoclip, website, etc.

  1. Active tectonics in Central Italy: Constraint from surface wave tomography and source moment tensor inversion

    International Nuclear Information System (INIS)

    regional scale, according to the resolution length of the data used, the crust exhibits clear layering and lateral variation in thickness: it is about 25 km thick below the Tuscan Metamorphic Complex (TMC), about 30 km below the Umbria-Marche geological Domain (UMD). Similarly a variation of the lithospheric thickness is observed: the lithospheric mantle (lid) is thin (about 30 km) below TMC, while it is about 70 km thick below UMD. A lithospheric root about 120 km wide, between the TMC and UMD, reaches a depth of at least 130 km. All along the profile a mantle wedge with thickness of about 20 km, is in-between the crust and the lid. This wedge exhibits low velocities and hence decouples the underlying lid from the crust. The retrieved crust and upper mantle structure beneath North-Central Italy in agreement with Bouguer anomaly and heat flow data supports delamination processes. The high velocity upper mantle underlying the mantle wedge is inferred to be sub-crustal lithospheric material delaminated from the overlying crust. (author)

    Fires play a relevant role in the global and regional carbon cycle, representing a remarkable source of CO2 and other greenhouse gases (GHG) that influence atmosphere budgets and climate. In addition, the wildfire increase projected in Southern Europe due to climate change (CC) and concurrent exacerbation of extreme weather conditions could also lead to a significant rise in GHG. Recently, in the context of the Italian National Adaptation Strategy to Climate Change (SNAC), several approaches were identified as valuable tools to adapt and mitigate the impacts of CC on wildfires, in order to reduce landscape susceptibility and to contribute to the efforts of carbon emission mitigation proposed within the Kyoto protocol. Active forest and fuel management (such as prescribed burning, fuel reduction and removal, weed and flammable shrub control, creation of fuel discontinuity) is recognised to be a key element to adapt and mitigate the impacts of CC on wildfires. Despite this, overall there is a lack of studies about the effectiveness of fire emission mitigation strategies. The current work aims to analyse the potential of a combination of fuel management practices in mitigating emissions from forest fires and evaluate valuable and viable options across Central and Southern Italy. These objectives were achieved throughout a retrospective application of an integrated approach combining a fire emission model (FOFEM - First Order Fire Effect Model) with spatially explicit, comprehensive, and accurate fire, vegetation and weather data for the period 2004-2012. Furthermore, a number of silvicultural techniques were combined to develop several fuel management scenarios and then tested to evaluate their potential in mitigating fire emissions.The preliminary results showed the crucial role of appropriate fuel, fire behavior, and weather data to reduce bias in quantifying the source and the composition of fire emissions and to attain reasonable estimations. Also, the current

  3. Isotopic and chemical investigation of water samples from Arno and Tiber rivers (Central Italy)

    International Nuclear Information System (INIS)

    Full text: The δ18O and δ2H isotope signature in the main rivers Tiber and Arno and principal tributaries, in Central Italy, were investigated along with major ion chemistry in order to evaluate the relative impact of natural processes and pollution on superficial water quality of related catchments. The Tiber Basin extends over an area of about 17156 km2 between the Apennine and Anti-Apennine Ridges to the Tyrrhenian Sea, in the Umbria and Latium regions. The main direction of fluid flow is NE-SW. Along its 402 km length, the Tiber River undergoes a vertical fall of about 1300 meters and crosses the town of Rome. With a surface area of about 8228 km2, northwest to Tiber Basin, the Arno Basin is located in Tuscany between the Apennine Ridge and the Tyrrhenian Sea. The Arno River flows westward crossing the tows of Florence and Pise. Along its 241 km length, the Arno River undergoes a vertical fall of about 1360 meters. Repeated surveys were carried out from 1996 to 2001 as to obtain water samples representative of high and low flow hydrologic conditions. The chemical and isotopic compositions of waters from both the systems were compared in order to assess the impact of local environmental factors on surface chemistry. Despite very similar climatic conditions, i.e. monthly precipitation amounts, average ambient temperature, temporal duration of dry, wet and intermediate seasons, the geochemical signature of surface waters results in different patterns in the two catchments. The Arno River shows a fairly homogeneous geochemical behaviour, characterised by a progressive enrichment of solute contents and 18O and 2H concentrations moving away from source to mouth, essentially due to the evaporation processes of the surface/soil waters. Both the chemical and isotopic data suggest that runoff control the chemical behaviour of river waters, according with the low average permeability of outcropping formations. In contrast, the Tiber River is characterised by a more

    Vico Lake, a volcanic meso-eutrophic lake in Central Italy, whose water is used for drinking and recreational activities, experienced the presence of the microcystins (MC) producing cyanobacterium Planktothrix rubescens. In order to assess the human health risks and to provide the local health authorities with a scientific basis for planning tailored monitoring activities, we studied P. rubescens ecology and toxicity for two years. P. rubescens generally dominated the phytoplankton community, alternating with Limnothrix redekei, potentially toxic. P. rubescens was distributed throughout the water column during winter; in summer it produced intense blooms where drinking water is collected (-20 m); here MC were detected all year round (0.5-5 μg/L), with implications for drinking water quality. In surface waters, MC posed no risk for recreational activities in summer, while in winter surface blooms and foams (containing up to 56 μg MC/L) can represent a risk for people and children practicing water sports and for animals consuming raw water. Total phosphorus, phosphate and inorganic nitrogen were not relevant to predict densities nor toxicity; however, a strong correlation between P. rubescens density and aminopeptidase ectoenzymatic activity, an enzyme involved in protein degradation, suggested a role of organic nitrogen for this species. The fraction of potentially toxic population, determined both as mcyB(+)/16SrDNA (10-100%) and as the MC/mcyB(+) cells (0.03-0.79 pg MC/cell), was much more variable than usually observed for P. rubescens. Differently from other Italian and European lakes, the correlation between cell density or the mcyB(+) cells and MC explained only ∼50 and 30% of MC variability, respectively: for Vico Lake, monitoring only cell or the mcyB(+) cell density is not sufficient to predict MC concentrations, and consequently to protect population health. Finally, during a winter bloom one site has been sampled weekly, showing that

    The eastern coast of Sicily is characterized by high population density, with three main cities (Messina, Catania and Siracusa) and many other touristic and industrial poles. At the same time, many possible sources of hazard exist in the area, from the highest volcano in Europe (Mt. Etna) to the several faults existing both inland and offshore in the Ionian Sea, and to the Hyblaean-Malta Escarpment running parallel to the coast close to the shoreline, incised by several scars and canyons. Seismic and tsunami catalogues account for such an intense activity, with some major events causing several damages and casualties, the main of which being the 1693 (Augusta) and 1908 (Messina) earthquakes and consequent tsunami. For such reasons the area of Siracusa and its surroundings was chosen as one of the test sites of the EU Project ASTARTE - Assessment, STrategy And Risk Reduction for Tsunamis in Europe (Grant 603839, 7th FP, ENV.2013.6.4-3), investigating many aspects of tsunami hazard, vulnerability and risk along the coasts of Europe. One of the main aims of the project is to assess the perception and preparedness of people and local authorities to natural hazards, with particular attention to tsunamis, in the test sites. This task was performed by realizing a questionnaire, subdivided into some sections, each one estimating a particular aspect: from the relation of the interviewed person with the site, to his/her perception of the risk and reaction in case of alert, to the knowledge of warning systems and evacuation procedures. The questions were submitted to local people and tourists in the town center of Siracusa, and also provided to delegates of local authorities, such as municipality and Civil Protection Department. The questionnaire results show a very low level of awareness of the risk connected to tsunamis, which is surprising if one considers the relatively recent catastrophic event of Messina, involving the whole eastern coast of Sicily.

    A 1-D velocity model for the Marche region (central Italy) was computed by inverting P- and S-wave arrival times of local earthquakes. A total of 160 seismic events with a minimum of ten observations, a travel time residual ≤ 0.8 s and an azimuthal gap lower than 180° have been selected. This “minimum 1-D velocity model” is complemented by station corrections, which can be used to take into account possible near-surface velocity heterogeneities beneath each station.

    Floating mires generally consist of emergent vegetation rooted in highly organic buoyant mats that rise and fall with changes in water level. Generally speaking, the entire floating mass (mat) is divided into a mat root zone and an underlying mat peat zone. Floating mires are distributed world-wide; large areas of floating marsh occur along rivers and lakes in Africa, the Danube Delta in Romania, the Amazon River in South America, and in the Mississippi River delta in USA, whereas smaller areas occur also in The Netherlands, Australia and Canada. While peat cores from ombrotrophic bogs have been often (and successfully) used to reconstruct changes in the atmospheric deposition of several metals (including Pb), no studies are present in literature about the possibility to use peat profiles from floating mires. To test the hypothesis that peat-forming floating mires could provide an exceptional tool for environmental studies, a complete, 4-m deep peat profile was collected in July 2012 from the floating island of Posta Fibreno, a relic mire in the Central Italy. This floating island has a diameter of ca. 30 m, a submerged thickness of about 3 m, and the vegetation is organized in concentric belts, from the Carex paniculata palisade to the Sphagnum palustre centre. The whole core was frozen cut each 1-to-2 cm (n =231), and Pb determined by quadrupole ICP-MS (at the ultraclean SWAMP lab, University of Alberta, Canada) in each sample throughout the first 100 cm, and in each odd-numbered slice for the remaining 300 cm. The 14C age dating of organic sediments (silty peat) isolated from the sample at 385 cm of depth revealed that the island probably formed ca. 700 yrs ago. Lead concentration trend shows at least two main zones of interest, i.e., a clear peak (ranging from 200 to 1600 ppm) between 110-115 cm of depth, probably corresponding to early 1960's - late 1970's, and a broad band (80-160 ppm) between 295-320 cm of depth, corresponding to approximately AD 1480

    Full Text Available Two field experiments were carried out in 2006 and 2007 in central Italy (42°57’N, 12°22’E, 165 m a.s.l. in order to investigate the influence of site, planting densities/spacings and cutting cycles on the biomass production of four poplar clones [(Populus – generosa – Populus nigra “Monviso” and “AF6”, Populus – canadensis “AF2”, Populus deltoides – Populus – canadensis “SIRIO”] selected for SRF. Hardwood cuttings of each clone were planted at two different densities and planting designs: a low density = 5500 cuttings ha-1 were placed in a single-row design; b high density = 11000 cuttings ha-1 were placed in a coupled-row design, and were tested with two cutting cycles: one-year cycle and two-year cycle. The experimental design was a split-plot with three replicates. The initial survival of clones was recorded after the establishment period. The number of shoots per plant (stool was determined after the first growing season. Plant height (height of the main stem, main stem diameter at a height of 1 m and of 1.3 m above the ground and biomass production were measured from each plot, every year at harvesting time at the end of the growing season. Plant samples were also taken in order to assess humidity content, lower and higher heating values (LHV and HHV and ash content of poplar biomass. All poplar clones showed a very high stool survival with values ranged from 95% to 99%. Monviso and AF2 can be advisable thanks to the higher biomass production than AF6 and Sirio. Considering planting density, low density (5500 plants ha-1 seems to be more advisable than high density (11000 plants ha-1 in order to obtain good biomass production with low planting cost. Considering cutting cycles, two-year cutting cycle allows higher biomass production (5.8 odt ha-1 year-1 than oneyear cutting cycle (4.7 odt ha-1 year-1, regardless of clones or density. Concerning main stem height and diameter some interesting equations were

  10. Hydrodynamic and isotopic characterization of a site contaminated by chlorinated solvents: Chienti River Valley, Central Italy

    International Nuclear Information System (INIS)

    Highlights: ► The fate of chlorinated solvents in groundwater in an alluvial aquifer has been investigated. ► Heterogeneity of the aquifer sediments causes vertical components of groundwater flow. ► Multilevel data shows the VOC’s stratification in the aquifer. ► Concentration and δ13C and δ37Cl data showed that dilution controls the VOC’s distribution. ► Biodegradation has been confirmed by isotope data only in low permeability layers. - Abstract: Contaminant sources have been attributed to shoe manufacturers in an alluvial aquifer located along 26 km2 in the Chienti River Valley, Central Italy. During the 1980s and 1990s, the main chlorinated compound used in the study area was 1,1,1-Trichloroethane (1,1,1-TCA), which was substituted by Perchloroethene (PCE) in the last 15 years. A hydrogeological conceptual model has been developed for the alluvial aquifer taking into account the presence of low permeability lenses, forming a multilayer semi-confined aquifer. Hydrodynamic tests (pumping and flowmeter heat-pulse tests) coupled with standard and multilevel hydrochemical and isotopic samplings were performed. Flowmeter tests showed the existence of vertical flow between aquifer levels having different permeability. Physical–chemical parameter logs agreed with the existence of a multilayer aquifer. Concentration data collected in 21 wells located downgradient of the different sources revealed VOC (Volatile Organic Compound) levels lower than 100 μg/L in the upper part of the valley and levels reaching about 200 μg/L in the near shore areas. PCE is the main compound present in the aquifer. No evidence of the presence of TCA was found in the upper areas of the Chienti Valley, but in the areas near the shore, TCA and its degradation products are predominant. Data collected at multilevels located at two sites (upper and near shore areas) to refine the results obtained in the regional survey show a stratification of the VOC concentrations; values of

  11. Chrysotile asbestos quantification in serpentinite quarries: a case study in Valmalenco, central Alps, northern Italy

    Cavallo, Alessandro

    2013-04-01

    Outcrops of serpentinites are usually strongly fractured and cataclastic, and the rock can only be used as ballast. However, in rare cases, like in Valmalenco (Central Alps, Northern Italy), fractures are regular and well spaced, and the rock mass has good geotechnical quality, ideal conditions for the extraction of dimension stone blocks. The Valmalenco Serpentinite is marketed worldwide as dimension and decorative stone, with remarkable mechanical properties and pleasing colours and textures. However, the same area was once subject to chrysotile asbestos mining, in the form of discrete veins along the main discontinuities of the rock mass. For this reason, airborne asbestos contamination can occur during the extraction and processing cycle of the rocks, therefore it is essential to locate and quantify asbestos in the rock mass, to reduce as much as possible the exposure risk. The first step was a detailed geostructural survey of each quarry, in order to characterize the main discontinuities (orientation, spacing, linear persistence, opening, filling), with special attention to the identification of fibrous minerals. The surveys was followed by extensive sampling of massive rocks, mineralized veins and fillings of fractures, and the cutting sludge derived from diamond wire cutting. Preliminary qualitative XRPD was performed on all samples, while quantitative analysis was carried out on the most representative samples of the main rock mass discontinuities. On the other hand, XRPD is not effective in the identification of asbestos percentages of less than 2% by weight, and the accurate distinction among the various serpentine polymorphs (antigorite, lizardite, chrysotile) is very difficult (if not impossible) when they are simultaneously present, due to their very similar basic structure and the strong structural disorder. The same samples were then analyzed by SEM-EDS (fiber counting after filtration on a polycarbonate filter), for a better distinction between

    International Nuclear Information System (INIS)

    The distribution and migration of radon and helium soil-gas concentrations in the Phlegraean Fields, Italy, are controlled by the tectonic features of the area. Radon is supplied from surficial sources and helium has both surficial and deep origins. There is no direct correlation between the two noble gases on a point-to-point basis but the areal distribution of both gases is similar, suggesting that the distribution is controlled primarily by fractures and movement of geothermal fluids

    Full Text Available The aim of this study was to determine the possibility of amaranth cultivation in Central Italy and to determine the optimum plant density. Field trials were carried out in 2011 and 2012 under non-irrigated conditions in Tuscany (43° 18’ N, 11° 47’ E. Twelve accessions of two amaranth species (Amaranthus cruentus L. and A. hypochondriacus L. were utilised. Genotypes were evaluated over a two-year period using a RCB design with three replicates. The effects of plant density were investigated in 2012. A with a split-plot design was used, where the A. cruentus accessions (AMES 5148, PI 511719 and PI 643045 constituted the main plots. Plant densities (7.5, 15, 30 and 60 plants m–2 constituted the subplots. Plants were transplanted at the 3-4 true leaf stage. Morphological traits were determined using 5 plants selected from the two central rows of the sampling area. Plots were hand-harvested and cleaned with a mechanical grid with appropriate sieve diameters. A. cruentus was shown to be more suitable to the Central Italy agro-ecological conditions than A. hypochondriacus. The accessions derived from Mexico (PI 477913, PI 576481, PI 643045, PI 643053, and PI 6495079, Guatemala (PI 511719 and Puerto Rico (AMES 5148, had both higher grain yields and a greater stability over the two-year period, with a mean grain production ranging from 2.8 to 3.2 t ha–1. The severe climatic stress in 2012 (high temperatures and aridity, resulted in a 43-60% reduction in seed production compared to that of the previous year. Under these conditions, PI 511719, AMES 26015, AMES 5386, AMES 5148, PI 477913 yielded on average 1.9 t ha–1. Yields of A. hypochondriacus were negligible in both years, probably attributable to greater photoperiod sensitivity, resulting in reduced flowering and delayed maturity. By increasing density up to 60 and 30 plants m–2 for PI 511719 and AMES 5148, respectively, grain production was increased by 55%. As the plant population

    specifically the analysis was focused on the evaluation of the effectiveness of coupling modeled or satellite-derived soil moisture with USLE-derived models in predicting event unit soil loss at the plot scale in a silty-clay soil in Central Italy. To this end was used the database of the Masse experimental station developed considering for a given erosive event (an event yielding a measurable soil loss) the simultaneous measures of the total runoff amount, Qe (mm), and soil loss per unit area, Ae (Mg-ha-1) at plot scale and of the rainfall data required to derive the erosivity factor Re according to Wischmeiser and Smith (1978), with a MIT=6 h (Bagarello et al., 2013; Todisco et al., 2012). To the purpose of this investigation only data collected on the λ = 22 m long plots were considered: 63 erosive events in the period 2008-2013, 18 occurred during the dry period (from June to September) and the other 45 in the complementary period (wet period). The models tested are the USLE/RUSLE and some USLE-derived formulations in which the event erosivity factor, Re, is corrected by the antecedent soil moisture, θ, and powered to an exponent α > 0 (α =1: linear model; α ≠ 1: power model). Both soil moisture data the satellite retrieved (θ = θsat) and the estimates (θ = θest) of Soil Water Balance model (Brocca et al., 2011) were tested. The results have been compared with those obtained by the USLE/RUSLE, USLE-M and USLE-MM models coupled with a parsimonious rainfall-runoff model, MILc, (Brocca et al. 2011) for the prediction of runoff volume (that in these models is the term used to correct the erosivity factor Re). The results showed that: including direct consideration of antecedent soil moisture and runoff in the event rainfall-runoff factor of the RUSLE/USLE enhanced the capacity of the model to account for variations in event soil loss when soil moisture and runoff volume are measured or predicted reasonably well; the accuracy of the original USLE/RUSLE model was

    Adult-type hypolactasia is a widespread condition throughout the world, causing lactose malabsorption. Several studies suggested that the identification of C/T-13910 and G/A-22018 mutations, located upstream the gene encoding the lactase-phlorizin hydrolase (LPH), is a useful tool for the differential diagnosis of hypolactasia. We evaluated the frequencies of C/T-13910 and G/A-22018 variants in a central-south Italian population and the usefulness of lactase deficiency genetic testing in the clinic practice. The genomic DNA of 1426 patients and 1000 healthy controls from central-south Italy was isolated from peripheral whole blood and genotyped for the C/T-13910 and G/A-22018 polymorphisms by high-resolution melting analysis (HRMA) and sequencing. The frequencies of genotypes in the 1426 patients analysed were as follows: 1077 CC/GG (75.5%), 287 CT/GA (20.1%), 24 TT/AA (1.7%), 38 CC/GA (2.7%). Only 64 out of 1426 (4.5%) performed also L-BHT test, 29 of which were negative for L-BHT also in presence of different genotypes. Among the 35 individuals with L-BHT positive, 34 were CC/GG and only one CT/GA. Although lactose genetic test is a good predictor of persistence/non-persistence lactase in specific population, its use in the central-south Italy population should be limited given the high prevalence of the CCGG diplotype in normal individuals.

    The Po Plain is a foredeep basin flanked by the two major and active orogens of the Italian Peninsula, the Alps to the North and the Apennines to the South. The basin has a quasi - triangular shape and grades longitudinally to the East in the Adriatic Sea. We used petroleum industry seismic reflection data acquired by ENI E&P in the Central Po Plain, over an area spanning about 6800 km2 from Lake Como to the W to Lake Garda to the E, and from the Lombardian Southern Alps to the N and the Emilia Apennines to the S, in order to analyze and interpret selected seismic reflectors and to define the evolution in space and time of the local active tectonic structures. Folds associated with underlying thrusts were recognized based on deformation recorded by two regional sequence boundary horizons, i.e. the ‘A' Surface (1.6 Myr) and the ‘R' Surface (0. 9 Myr; e.g., Carcano & Piccin, 2002; Muttoni et al., 2003), characterized by good stratigraphic and age bracketing, and marking significant changes in the sedimentary architecture of the Po Basin. Age controls are based on stratigraphic, paleontological and magnetostratigraphic analysis by ENI E&P and Regione Lombardia (Carcano & Piccin, 2002; Scardia et al., 2006). The analysis of strain recorded by these horizons allowed us to: A) recognize a belt of active fold and thrust structures, each 10 to 20 km long, arranged with an en-echelon pattern across the whole Po Basin, and B) analyze their evolution over the Quaternary. 'A' surface (1.6 Myr) The ‘A' surface has been mapped over about 7800 Km2. From North to South four major morphobathymetric domains can be defined in the Pleistocene marine Po Basin: an Alpine platform domain, a slope that links it with the wider central basin domain, a smaller and steeper slope and an Apennine platform domain. The basin shape has an asymmetric transversal profile and is ca. 40 km wide. Several tectonic structures affect this surface. On the Alpine platform domain two small structures

    Full Text Available Perchloroethene, Trichloroethene, and other chlorinated solvents are widespread groundwater pollutants. They form Dense Non Aqueous Phase Liquids (DNAPLs that sink through permeable groundwater aquifers until non-permeable zone is reached. In Italy there are many situations of serious contamination of groundwater that might compromise their use in industry, agriculture, private, as the critical case of a Central Italy valley located in the province of Teramo (Val Vibrata, characterized by a significant chlorinated solvents contamination. Data from the various monitoring campaigns that have taken place over time were collected, and new samplings were carried out, resulting in a complete database. The data matrix was processed with a multivariate statistic analysis (in particular Principal Components Analysis, PCA and was then imported into Geographic Information System (GIS, to obtain a model of the contamination. A microcosm anaerobic study was utilized to assess the potential for in situ natural or enhanced bioremediation. Most of the microcosms were positive for dechlorination, particularly those inoculated with a mineral medium. This indicate the presence of an active native dechlorinating population in the subsurface, probably inhibited by co-contaminants in the groundwater, or more likely by the absence or lack of nutritional factors. Among the tested electron donors (i.e., yeast extract, lactate, and butyrate lactate and butyrate enhanced dechlorination of chlorinated compounds. PCA and GIS studies allowed delimiting the contamination; the microcosm study helped to identify the conditions to promote the bioremediation of the area.

    This report describes an increased number of cases of Chikungunya virus (CHIKV) infection imported in northern Italy (Emilia-Romagna region) during the period May-September 2014, indicating that the recent spread of CHIKV and its establishment in the Caribbean and in central America, resulted in a high number of imported cases in Europe, thus representing a threat to public health. From May to September 2014, 14 imported cases of CHIKV infection were diagnosed; the patients were returning to Italy from Dominican Republic (n = 6), Haiti (n = 3), Guadeloupe (n = 2), Martinique (n = 1), Puerto Rico (n = 1) and Venezuela (n = 1). Phylogenetic analysis performed on the envelope protein (E1) gene sequences, obtained from plasma samples from two patients, indicated that the virus strain belongs to the Caribbean clade of the Asian genotype currently circulating in the Caribbean and Americas. The rise in the number of imported cases of CHIKV infection should increase healthcare professionals' awareness of the epidemiological situation and clinical presentation of CHIKV infection in order to enhance surveillance and early diagnosis in the forthcoming season of vector activity in Europe and North America.

    Full Text Available The sustainability of a small-scale self-consumption wood-energy chain for heat generation in central Italy was analyzed from a technical, economic and energetic point of view. A micro-chain was developed within the CRA-ING farm at Monterotondo (Rome, Italy: The purpose of this system was to produce biomass for supplying a heating plant within the CRA-ING property as a substitute for diesel fuel. A poplar short rotation coppice, established with clones AF2, AF6 and Monviso, fed the micro-chain. The rotation was biennial. The average plantation production (Mgd.m.·ha−1·year−1 was 10.2, with a maximum of 13.53 for the twin-rows AF2 and a minimum of 8.00 for the single-row Monviso. The economic assessment was based on the Net Present Value (NPV method and the equivalent annuity cost, and found an average saving of 15.60 €·GJ−1 of heat generated by the wood chips heating system in comparison with the diesel heating system over a 10 year lifetime of the thermal power plant. The energy assessment of the poplar plantation, carried out using the Gross Energy Requirements method, reported an energy output/input ratio of 12.3. The energy output/input ratio of the whole micro-chain was 4.5.

  3. The "green stones" of Valtellina and Valchiavenna (central Alps, northern Italy)

    Valtellina and Val Chiavenna (Sondrio, Central Alps, northern Italy) are traditionally areas of production of building and ornamental stones (e.g. Serizzo Ghiandone, Serizzo Valmasino, San Fedelino Granite), and among these the "green stones" have a leading position. These stones had an extensive use in Lombardy, as well as abroad (e.g Switzerland). The "green stones" are related to the two mafic-ultramafic bodies of Valmalenco and Chiavenna, where the two largest quarrying districts of the Province of Sondrio are located. Until the early decades of the XX century, serpentinites (and other lithologies from Valtellina) were also extracted from the erratic boulders of Brianza (north of Milan), but at present time the law protects the few remaining boulders. The extracted and processed materials are various: serpentinites, ophicalcites, soapstones. Even the "Stone of Tresivio", used in the past in important monuments of Valtellina, could be classified among the "green stones" in a broad sense: it is a green chloritic schist with scarce and thin ferriferous calcitic veins, pertaining to the sedimentary "Servino" Formation. In recent times, the ancient quarries of this stone were rediscovered near the homonymous village, a few kilometers from Sondrio. There are also historic reports about other "green stones", used in ancient times, such as the "Stone of Grosio", a chloritic schist, and the "Bormio Prasinite". Currently the extraction and processing of "green stones" occurs mostly in Valmalenco, with 22 active serpentinite quarries and a gross volume of 70000 m3 extracted per year, with a yield of about 50%. The Malenco serpentinite (interpreted as sub-continental mantle rocks) forms a 1-2 km thick tabular body, outcropping over an area of about 170 km2, almost entirely confined within the boundaries of the valley. The antigoritic serpentinites (with variable amounts of olivine, clinopyroxene, chlorite and magnetite) are moderately up to strongly foliated, sometimes

    Floating mires are defined by the occurrence of emergent vegetation rooted in highly organic buoyant mats that rise and fall with changes in water level. Islands floating and moving on a lake naturally were already described by Pliny the Elder in his Naturalis historia almost two millennia ago. Actually, he devoted a whole chapter of Naturalis historia to "Of Islands Ever Floating and Swimming", reporting how certain isles were always waving and never stood still. The status of "flotant" has been defined transitory; in fact, these small isles often disappear, in most of the cases because of a transition from floating island to firm land during decades is likely to happen. That is why most of the floating islands described by Pliny the Elder (e.g., Lacus Fundanus, Lacus Cutiliensis, Lacus Mutinensis, Lacus Statoniensis, Lacus Tarquiniensis, Lydia Calaminae, Lacus Vadimonis) do not exist anymore. In the present study, peat formation and organic matter evolution were investigated in order to understand how these peculiar environments form, and how stable actually they are. In fact, it is hoped that peat-forming floating mires could provide an exceptional tool for environmental studies, since much of their evolution, as well as the changes of the surrounding areas, is recorded in their peat deposits. A complete, 4-m deep peat core was collected in July 2012 from the floating island of Posta Fibreno, a relic mire in the Central Italy. This floating island has a diameter of ca. 30 m, a submerged thickness of about 3 m, and the vegetation is organized in concentric belts, from the Carex paniculata palisade to the Sphagnum centre. Here, some of the southernmost Italian populations of Sphagnum palustre occur. The 14C age dating of organic sediments isolated from the sample at 385 cm of depth revealed that the island formed ca. 700 yrs ago (620±30 yr BP). The top 100 cm, consisting almost exclusively of Sphagnum mosses, show a very low bulk density (avg., 0.03±0.01 g cm

    In the case of unidentified bodies the estimation of the period since death or of the season of death plays an important role to focus the attention on a reduced number of people among the ones reported missing. Forensic entomology can be one of the most important methods for these estimations, as occurred in this case. Flies are typically the first insects to colonize a dead body. The case reported here concerns the colonisation by insects of a male body in advanced decay found during the winter in Central Italy. This case is of particular interest as few data are available on the entomological evidence in the cold season. In particular, in this case we recovered Calliphora loewi (Calliphoridae), a species never collected before on dead bodies in Southern Europe. Larvae of the black soldier fly Hermetia illucens (Stratiomyidae), pupae and larvae belonging to genus Hydrothea (Muscidae), and Necrobia rufipes (Cleridae) specimens were also collected. The estimated PMI enabled identification of the cadaver, confirmed by DNA analysis. PMID:21282022

    Full Text Available The present work aims to establish relationships between shoreline historical variations (close to the river mouths and slope dynamics on mountain and hilly areas: these are considered as fundamental physiographic units of the Adriatic central Italy. The study deals about the deltaic system of the Chienti river, which is representative of the deltaic systems of the main Marchean rivers. Goal is to recognize possible geomorphological indicators of climatic variations during late Holocene. Debris flows on the Sibillini Mts were analysed and interpreted. Their activation can be associated with: late Pleistocene-early Holocene deglaciation, with regard to the oldest phenomena; agricultural, forestry and grazing activities during the Late Middle Ages, even though evidence of climatic conditioning is also present. Moreover, some important landslide phenomena on the high hilly areas were examined: historical data demonstrated an intense post-Middle Age activity (XVth-XVIIIth centuries related to the strong rainfall increase as a consequence of climatic worsening.Dans cette note, sont interprétées quelques formes mineures du paysage physique, utilisables en tant qu'indicateurs géomorphologiques des variations climatiques de l'Holocène supérieur.

    Prevalence of anti-hepatitis E virus (HEV) antibodies is highly variable in developed countries, which seems partly due to differences in assay sensitivity. Using validated sensitive assays, we tested 313 blood donors attending a hospital transfusion unit in central Italy in January and February 2014 for anti-HEV IgG and IgM and HEV RNA. Data on HEV exposure were collected from all donors. Overall anti-HEV IgG prevalence was 49% (153/313). Eating raw dried pig-liver sausage was the only independent predictor of HEV infection (adjusted prevalence rate ratio = 2.14; 95% confidence interval: 1.23-3.74). Three donors were positive for either anti-HEV IgM (n = 2; 0.6%) or HEV RNA (n = 2; 0.6%); they were completely asymptomatic, without alanine aminotransferase (ALT) abnormalities. Of the two HEV RNA-positive donors (both harbouring genotype 3), one was anti-HEV IgG- and IgM-positive, the other was anti-HEV IgG- and IgM-negative. The third donor was positive for anti-HEV IgG and IgM but HEV RNA-negative. HEV infection is therefore hyperendemic among blood donors (80% men 18-64 years-old) from central Italy and associated with local dietary habits. Nearly 1% of donors have acute or recent infection, implying potential transmission to blood recipients. Neither ALT nor anti-HEV IgM testing seems useful to prevent transfusion-transmitted HEV infection. PMID:27494608

    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.

    Identification of active faults in abruzzo area (central italy) through the analysis of geological, seismological and gravimetric data The aim of this study is to identify and constrain the geometry of the seismogenic structures (active, outcropping and buried fault systems) of the Abruzzo area (central Italy), through an integrated analysis of geo-structural, seismic and gravimetric data. We generated three thematic: "faults", "earthquakes" and "gravimetric" data: i) The fault dataset consists of data extracted from the available structural and geological maps (ITHACA catalogue; the "Neotectonic Map of Italy" 1:500.000; several geological sheets 1:50.000 from ISPRA CARG project; the Geological Map 1:100.000 Sheet 1), and many geological studies. ii) The earthquakes datasets was created by merging the data from historical and instrumental Catalogues (CPTI04 and CPTI11; ISIDE - INGV). iii) The gravimetric datasets consists in the Multiscale Derivative Analysis (MDA) of the Bouguer anomaly map of the area, whose maxima show the presence of density lineaments. The merge of these datasets in GIS environment, highlighted four possible scenarios of correlation between faults, earthquakes and MDA maxima: 1) the existence of active faults, revealed by a strong correlation between epicentral location of seismic clusters, fault positions and MDA maxima; 2) the existence of buried active faults, highlighted by a good correlation between MDA maxima and epicentral positions, without correspondence with faults known from geological data; 3) the existence of inactive or silent faults, detected by the presence of faults reported in the geological datasets and literature which are associated with MDA maxima, without correlation of earthquakes; 4) the existence of faults not correlated with MDA maxima; this could be due to faults putting in contact two lithologies with a similar density.

    Full Text Available In the Early Holocene, the central Marches (Italy underwent a widespread development of forest cover and soils which drastically reduced slope degradation and related aggradation processes in riverbeds. In such conditions, streams deeply incised the previous alluvial sediments. In the Apennine sectors, linear erosion was locally prevented by the growth of travertine dams in correspondence with river channel knickpoints and waterfalls. Fluvial deposition prevailed in the peri-Adriatic hilly belt, where river valleys still extended from the present coastline to the uprising Adriatic Sea, as testified by a 50-m-deep cored log, drilled near the Potenza River mouth. Several archaeological sites, ranging from the Mesolithic to the Aeneolithic, testify the recurrent presence of small-scale human groups on the alluvial plains of the lower valley sectors. Sandy-clayey sediments, emplaced by flooding episodes, repeatedly buried these settlements which were commonly located on the riversides. Small Aeneolithic communities were also present in the mountain sectors, around travertine-dammed swampy-lacustrine basins. On top of the sequences, Bronze Age sites were locally found. Widespread deforestation started in the early Iron Age (about 3000 yr BP, when alluvial plains and terraces were permanently occupied by large-scale human settlements. Geo-archaeological evidence of systematic deforestation at 2950 ± 50 14C yr BP, consisting of numerous round-shaped 1.5-3 m wide hollows, filled with soil sediments and upturned blocks of alluvial gravels, were found on top of a fluvial terrace in the Esino River basin. From the Iron Age to recent historical times, notwithstanding the progressive increase of debris supply to the drainage systems due to the spreading agricultural-pastoral activities, erosion dominated almost everywhere in the Marches rivers, likely induced by climatic factors.À l’Holocène inférieur, comme ailleurs dans le monde, les Marches

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

    Full Text Available Abstract Background The number of immigrants has increased in Italy in the last twenty years (7.2% of the Italian population, as have infants of foreign-born parents, but scanty evidence on perinatal outcomes is available. The aim of this study was to investigate whether infants of foreign-born mothers living in Italy have different odds of adverse perinatal outcomes compared to those of native-born mothers, and if such measures changed over two periods. Methods The source of this area-based study was the regional hospital discharge database that records perinatal information on all births in the Lazio region. We analysed 296,739 singleton births born between 1996-1998 and 2006-2008. The exposure variable was the mother's region of birth. We considered five outcomes of perinatal health. We estimated crude and adjusted odds ratios and 95% confidence intervals (CIs to evaluate the association between mother's region of birth and perinatal outcomes. Results Perinatal outcomes were worse among infants of immigrant compared to Italian mothers, especially for sub-Saharan and west Africans, with the following crude ORs (in 1996-1998 and 2006-2008 respectively: 1.80 (95%CI:1.44-2.28 and 1.95 (95%CI:1.72-2.21 for very preterm births, and 1.32 (95%CI:1.16-1.50 and 1.32 (95%CI:1.25-1.39 for preterm births; 1.18 (95%CI:0.99-1.40 and 1.17 (95%CI:1.03-1.34 for a low Apgar score; 1.22 (95%CI:1.15-1.31 and 1.24 (95%CI:1.17-1.32 for the presence of respiratory diseases; 1.47 (95%CI:1.30-1.66 and 1.45 (95%CI:1.34-1.57 for the need for special or intensive neonatal care/in-hospital deaths; and 1.03 (95%CI:0.93-1.15 and 1.07 (95%CI:1.00-1.15 for congenital malformations. Overall, time did not affect the odds of outcomes differently between immigrant and Italian mothers and most outcomes improved over time among all infants. None of the risk factors considered confounded the associations. Conclusion Our findings suggest that migrant status is a risk factor for

    Highlights: > Isotopic compositions of karstic springs in central Italy have been reviewed. > Isotopic gradients of rainfalls for elevations have been evaluated in an Alpine valley. > Karstic drops have been calculated by using isotopic compositions of springs. > Isotopic compositions of rainfalls in central Italy have been re-calculated using the isotopic compositions of karstic springs. - Abstract: This paper describes an indirect method to calculate the isotopic composition of rainfall by using the isotopic composition of karst springs fed by waters circulating in the most important regional aquifer of central Italy, i.e. the Mesozoic limestone sequence that forms the backbone of the Apennines. By using {delta}{sup 18}O and {delta}D data and the {delta}{sup 18}O (and/or {delta}D) average gradient for elevation, evaluated through the use of literature rainfall data and new measurements from a typical Alpine valley in northern Italy, the altitude of precipitation of their parent water has been re-calculated. Vertical descents of more than 2000 m, from recharge to discharge, have been assessed in some high flow-rate cold springs in the morphologically steep Adriatic sector of central Italy. A clear correlation between the vertical descents and more negative isotopic compositions at their relative emergence elevations is highlighted. In contrast, in the Tyrrhenian sector lower karstic drops (generally lower than 500 m) correlate with less negative isotopic composition of recharge areas. The {delta}{sup 18}O iso-contour map of the 'recalculated' parent rainfall in central Italy is more detailed than any possible isotopic map of rainfall made using pluviometers, unless large number of rainfall collectors were deployed on mountaintops. The data also show that the isotopic composition of rainfall depends on the source of the storm water. In particular, precipitation is isotopically heavier when originating in the Mediterranean Sea, and lighter when formed in

  17. Particulate Matter deposition on Quercus ilex leaves in an industrial city of central Italy

    International Nuclear Information System (INIS)

    A number of studies have focused on urban trees to understand their mitigation capacity of air pollution. In this study particulate matter (PM) deposition on Quercus ilex leaves was quantitatively analyzed in four districts of the City of Terni (Italy) for three periods of the year. Fine (between 0.2 and 2.5 μm) and Large (between 2.5 and 10 μm) PM fractions were analyzed. Mean PM deposition value on Quercus ilex leaves was 20.6 μg cm−2. Variations in PM deposition correlated with distance to main roads and downwind position relatively to industrial area. Epicuticular waxes were measured and related to accumulated PM. For Fine PM deposited in waxes we observed a higher value (40% of total Fine PM) than Large PM (4% of total Large PM). Results from this study allow to increase our understanding about air pollution interactions with urban vegetation and could be hopefully taken into account when guidelines for local urban green management are realized. - Highlights: • A quantitative analysis of Particulate Matter deposition on urban Quercus ilex leaves was implemented. • Deposition data were correlated with pollutants sources such as roads and local steel factory, and with epicuticular waxes. • Results provide new insight about the capacity of trees in removing pollutants in urban environment. - This paper is providing useful information on PM deposition on urban vegetation

    Full Text Available Traditional knowledge of local plant uses is rapidly fading away, especially in rural Mediterranean areas. We carried out ethnobotanical research in 2010-2011 in order to investigate the local knowledge of wild plants in the Tolfa–Cerite–Manziate area of Italy (Latium, district of Rome. We carried out a total of 45 semi-structured interviews with farmers, herders, and fishers. Here, a simple diachronic comparison is made between the current study and a previous one conducted in some of the villages of the study area to highlight potential losses of traditional knowledge of local plants. We documented a total of 102 plant species, belonging to 48 families, along with their uses (excluding food uses. We also reported some non-plant based remedies that were primarily used in veterinary medicine. Some plant uses, especially for making handicrafts, have not been reported previously (e.g., those of Celtis australis L. Cannabaceae, Betula pendula Roth Betulaceae. Many plant uses are no longer remembered in the area, which indicates a loss of local ethnobotanical knowledge.

    In this work we show that the main springs of the central Apennine transport a total amount of heat of ∼2.2 109 J s−1. Most of this heat (57%) is the result of geothermal warming while the remaining 43% is due to gravitational potential energy dissipation. This result indicates that a large area of the central Apennines is very hot with heat flux values 4300 mWm−2. These values are higher than those measured in the magmatic and famously geothermal provinces of Tuscany and Latium a...

  20. Hydrogeochemical processes controlling water and dissolved gas chemistry at the Accesa sinkhole (southern Tuscany, central Italy

    Full Text Available The 38.5 m deep Lake Accesa is a sinkhole located in southern Tuscany (Italy that shows a peculiar water composition, being characterized by relatively high total dissolved solids (TDS values (2 g L-1 and a Ca(Mg-SO4 geochemical facies. The presence of significant amounts of extra-atmospheric gases (CO2 and CH4, which increase their concentrations with depth, is also recognized. These chemical features, mimicking those commonly shown by volcanic lakes fed by hydrothermal-magmatic reservoirs, are consistent with those of mineral springs emerging in the study area whose chemistry is produced by the interaction of meteoric-derived waters with Mesozoic carbonates and Triassic evaporites. Although the lake has a pronounced thermocline, water chemistry does not show significant changes along the vertical profile. Lake water balance calculations demonstrate that Lake Accesa has >90% of its water supply from sublacustrine springs whose subterranean pathways are controlled by the local structural assessment that likely determined the sinking event, the resulting funnel-shape being then filled by the Accesa waters. Such a huge water inflow from the lake bottom (~9·106 m3 yr-1 feeds the lake effluent (Bruna River and promotes the formation of water currents, which are able to prevent the establishment of a vertical density gradient. Consequently, a continuous mixing along the whole vertical water column is established. Changes of the drainage system by the deep-originated waters in the nearby former mining district have strongly affected the outflow rates of the local mineral springs; thus, future intervention associated with the ongoing remediation activities should carefully be evaluated to preserve the peculiar chemical features of Lake Accesa.

    Full Text Available Abstract Seasonal egg (or oocyst output of gastro-intestinal parasites of wild ungulates was studied in a Mediterranean protected area, the Monti Livornesi Park (Livorno, Tuscany region, Central Italy. Samples of faeces of wild boars (Sus scrofa and mouflons (Ovis ammon were collected monthly for one year. The observed trends of egg output were analysed taking into account seasonal variations of temperature and rainfall, life-cycle and survival strategy of parasites, and health condition of hosts. In our Mediterranean study area, the peaks of egg output appear in different months according to different biology and survival strategies of parasites. Riassunto Emissione stagionale di uova di parassiti gastrointestinali in cinghiali (Sus scrofa e in mufloni (Ovis ammon di un’area mediterranea (Italia centrale. E' stata studiata l'emissione stagionale di uova (o oocisti di parassiti nelle feci di ungulati selvatici in una zona mediterranea protetta, il Parco dei Monti Livornesi (Livorno, Toscana, Italia Centrale. Per un anno sono stati raccolti mensilmente campioni di feci di Cinghiale (Sus scrofa e di Muflone (Ovis ammon. Gli andamenti osservati di emissione di uova sono stati analizzati tenendo conto delle variazioni di temperatura e piovosità stagionali, del ciclo biologico e della strategia di sopravvivenza dei parassiti, e delle condizioni sanitarie dell'ospite. E’ risultato che in una zona mediterranea come quella considerata i picchi di emissione di uova appaiono in mesi differenti in relazione alla biologia e alle strategie di sopravvivenza dei diversi parassiti.

    2011-05-01

    A hydrogeological study was undertaken to define the groundwater circulation in the Santa Croce area (Tuscany, central Italy) where the existing multilayered aquifer has long been intensively exploited. Investigations carried out on about 150 wells revealed the existence of a deep piezometric depression (to 20 m below sea level) which drains groundwater from the entire surrounding area. Samples from about 70 water points, collected twice in 2007, were analysed for major elements and stable isotope composition. Three major groups of waters, which mix in the study area, have been distinguished: (1) waters of the Ca-Mg-HCO3 type mainly flowing along the Arno River Plain; (2) waters of the Na-K-Cl/Ca-Mg-HCO3-SO4, type with SO4 content up to 275 mg/L, inflowing from the Pisane Hills; (3) relatively high-salinity waters mainly of the Na-HCO3 type which, with Cl concentrations up to 750 mg/L, likely arise from a normal fault located at the foot of the northern hills. The characteristics of the different components are greatly affected by significant modifying processes such as cation exchange and sulfate reduction. The achieved conceptual model suggests the southern hills as the main recharging area of the aquifer system from which water circulation, characterized by pathways of different length and depth, develops.

    The juxtaposed contraction and extension observed in the crust of the Italian Apennines and elsewhere has, for a long time, attracted the attention of geoscientists and is a long-standing enigmatic feature. Several models, invoking mainly external forces, have been put forward to explain the close association of these two end-member deformation mechanisms clearly observed by geophysical and geological investigations. These models appeal to interactions along plate margins or at the base of the lithosphere such as back-arc extension or shear tractions from mantle flow or to subduction processes such as slab roll back, retreat or pull and detachment. We present here a revisited crust and upper mantle model that supports delamination processes beneath North-Central Italy and provides a new background for the genesis and age of the recent magmatism in Tuscany. Although external forces must have been important in the building up of the Apennines, we show that internal buoyancy forces solely can explain the coexist...

    Epiphytic lichens and top-soils from the Mt. Amiata geothermal field (central Italy) were analyzed for their As, B and Hg content. Three areas were selected: (1) Abbadia S. Salvatore, where a large Hg mine with smelting and roasting plant was located; (2) Piancastagnaio, where there are geothermal power plants; (3) a remote site far from mines and geothermal power plants. The results showed that the geothermal power plants do not represent a macroscopic source of arsenic and boron contamination in the area. As far as mercury is concerned, at the Hg mining area of Abbadia S. Salvatore concentrations were extremely high both in soil and epiphytic lichens, and the anomalous content in these organisms was due to the uptake of elemental mercury originating from soil degassing. At the geothermal area of Piancastagnaio, soil mercury was not different from that in the control area, but Hg in lichens was almost twice the control levels, suggesting that the gaseous emissions from the geothermal power plants are an important source of air contamination.

    Full Text Available A coupled empirical approach for studying possible correlations among rainfall, vegetation segmentation and landslide occurrence is discussed. To reveal such links two important rainfall events, occurred over the Esino river basin in central Italy, in November 2013 and May 2014, were analysed. The correlation between rainfall and landslides was carried out applying an intensity–duration (ID threshold method, whereas the correlation between vegetation segmentation and landslides was investigated using the Morphological Spatial Pattern Analysis (MSPA. This coupled approach represents an attempt to find both timing and location of landslide occurrence through an empirical (black box analysis. Results showed that: (i the ID minimum threshold proposed in a previous study (Gioia et al., 2015 was verified as an effective equation to assess the rainfall conditions likely to trigger landslides in the study area ("when", and (ii the Core areas and the fragmented vegetation structures defined by the MSPA were the most affected by slope failures ("where". These encouraging findings prompt for additional testing and application of such coupled empirical approach to possibly achieve an integrated basis for landslide forecasting.

    Very high temperature, Ca-rich alkaline magma intruded an argillite formation at Colle Fabbri, Central Italy, producing cordierite-tridymite metamorphism in the country rocks. An intense Ba-rich sulphate-carbonate-alkaline hydrothermal plume produced a zone of mineralization several meters thick around the igneous body. Reaction of hydrothermal fluids with country rocks formed calcium-silicate-hydrate (CSH), i.e., tobermorite-afwillite-jennite; calcium-aluminum-silicate-hydrate (CASH) — "cement" phases - i.e., thaumasite, strätlingite and an ettringite-like phase and several different species of zeolites: chabazite-Ca, willhendersonite, gismon-dine, three phases bearing Ca with the same or perhaps lower symmetry of phillipsite-Ca, levyne-Ca and the Ca-rich analogue of merlinoite. In addition, apophyllite-(KF) and/or apophyllite-(KOH), Ca-Ba-carbonates, portlandite and sulphates were present. A new polymorph from the pyrrhotite group, containing three layers of sphalerite-type structure in the unit cell, is reported for the first time. Such a complex association is unique. Most of these minerals are specifically related to hydration processes of: (1) pyrometamorphic metacarbonate/metapelitic rocks (natural analogues of cement clinkers); (2) mineralization between intrusive stocks and slates; and (3) high-calcium, alkaline igneous rocks such as melilitites and foidites as well as carbonatites. The Colle Fabbri outcrop offers an opportunity to study in situ complex crystalline overgrowth and specific crystal chemistry in mineral phases formed in igneous to hydrothermal conditions.

    A multi-sensor analysis of convective precipitation events that occurred in central Italy, in autumn 2012 during the HyMeX (Hydrological cycle in the Mediterranean eXperiment) Special Observation Period (SOP) 1.1 is presented. Various microphysical properties of liquid and solid hydrometeors were examined to assess their relationship with lightning activity. The instrumentation used consisted of a C-band dual-polarization weather radar, a 2-D video disdrometer, and a lightning network. A fuzzy logic based hydrometeor classification algorithm was tuned and optimized for the detection of graupel from C-band dual-polarization radar measurements. Graupel ice water content was then retrieved and related to lightning activity. A linear correlation was found between the total mass of graupel above the 0° isothermal and the number of strokes detected by the lightning network in agreement with model outputs, which confirms the importance of ice in the electrical charging of convective clouds, although differences were noticed among events. Parameters of the gamma raindrop size distribution measured by a 2-D video disdrometer, revealed the transition from convective to stratiform regime during the event and where related. However, lightning activity was not always recorded when the precipitation regime was classified as convective. More robust relationships were found relating lightning activity to graupel.

    Full Text Available Tectonomagnetic field observations from absolute magnetic field levels have been collected in Central Italy since 1989 by means of a network of four absolute magnetometer stations, including the geomagnetic observatory of L'Aquila (42°23 N, 13°19 E used as reference for differentiation; also electromagnetic variations from VLF signals have been recorded in the last years by means of VLF search coil wide-band antennas. Many reports proved the occurrence of electromagnetic effects clearly related to tectonic events (seismic and volcanic activity in active areas of our planet. In this paper we show the variation of some electromagnetic parameters which could be related to local and regional seismic activity for the most recent years 2002 and 2003. We also report the seismic activity recorded in this area by the Italian seismic national network. Some tentative analysis (in the wavelets and statistical approach on the historical and recent dataset allow a better characterization of electromagnetic properties of the study area, at different temporal and spatial scales.

    1997-01-01

    Full Text Available Androniscus dentiger is a terrestrial isopod distributed from Great Britain to North Africa, inhabiting humid edafic environments, superficial underground compartments and both natural and artificial caves. In this study allozyme data have been used to investigate the geographic variation and the genetic relationships of several populations of A. dentiger from Central Italy, using as outgroups populations from four congeneric species, A. calcivagus, A. cfr. subterraneus, A. spelaeorum, and A. degener. Multivariate analysis of A. dentiger allele frequencies indicates the existence of a group of populations (group A distributed in a wide geographic area which are genetically slightly differentiated, and several populations (arbitrarily defined as group B which show differentiation levels comparable to those observed between the morphologically well differentiated species. The low valley of the river Tiber seems to act as an effective geographic barrier between the populations from group A and the remaining ones. The genetic divergence between populations within the group A seems to have a recent origin. This is suggested by the low genetic distances and heterozygosity values within the group A, and by the very low number of private alleles occurring in this group. The high degree of intraspecific and interspecific genetic differentiation is not consistent with the levels of morphological differentiation traditionally used to distinguish different species within this genus. On the whole, these data suggest that A. dentiger might be considered as a complex of cryptic/sibling species.

    Full Text Available Abstract Background Cystic fibrosis (CF is a multisystem disorder characterised by mutations of the CFTR gene, which encodes for an important component in the coordination of electrolyte movement across of epithelial cell membranes. Symptoms are pulmonary disease, pancreatic exocrine insufficiency, male infertility and elevated sweat concentrations. The CFTR gene has numerous mutations (>1000 and functionally important polymorphisms (>200. Early identification is important to provide appropriate therapeutic interventions, prognostic and genetic counselling and to ensure access to specialised medical services. However, molecular diagnosis by direct mutation screening has proved difficult in certain ethnic groups due to allelic heterogeneity and variable frequency of causative mutations. Methods We applied a gene scanning approach using DHPLC system for analysing specifically all CFTR exons and characterise sequence variations in a subgroup of CF Italian patients from the Lazio region (Central Italy characterised by an extensive allelic heterogeneity. Results We have identified a total of 36 different mutations representing 88% of the CF chromosomes. Among these are two novel CFTR mutations, including one missense (H199R and one microdeletion (4167delCTAAGCC. Conclusion Using this approach, we were able to increase our standard power rate of mutation detection of about 11% (77% vs. 88%.

    Understanding spatial-temporal variability, magnitude and different expressions of Quaternary millennial-scale palaeoclimatic changes is one of the frontier challenges of modern palaeoclimatology. Addressing this issue requires the acquisition of regionally representative, and ideally independently-dated, records of climatic variability. Multiproxy record (stable isotopes, XRF, MS, %CaCO3) from lacustrine succession of Sulmona basin (central Italy), highlights climatic and hydrological variability at orbital to millennial scales between MIS20 and MIS18. The record highlights the presence of interesting millennial scale variability within MIS19, considered to be the best orbital analogue of the current interglacial. The presence of several tephra layers precisely dated by 40Ar/39Ar technique, allow placement of the record within a robust time frame. Assembling a high-resolution paleoclimatic record for MIS19 anchored to a high-precision 40Ar/39Ar chronology, it is possible to show that the MIS 19c interglacial started shortly before the boreal summer insolation and obliquity maximum/precession minimum at 790-788 ka, and ended 11.6 ± 2.3 kyr later, when orbital parameters assumed a configuration similar to the present one.

    Full Text Available Increasing the river habitat safeguard level is one of the main actions proposed by the European Water Framework Directive in the field of biomonitoring. To do so, watercourses within the same hydroecoregions (that is, homogeneous areas based on climate, geology and topography ought to be compared. In addition, the source distance was thought to play an important role in comparing rivers and then planning monitoring activities. The purpose of this study was to evaluate if both hydroecoregion and source distance affect the response (in terms of taxa assemblage of one of the most used group in the river monitoring activities: the benthic macroinvertebrate. Here we proposed the comparative influence of hydroecoregion and source distance on the invertebrate assemblage in Mediterranean rivers of central Italy. Our statistical outputs highlighted how macroinvertebrate differed for both hydroecoregions and source distance ranks. In particular, no differences were found among sites of different (1 source distance ranks and (2 hydroecoregion (that is, when this two descriptors were analyzed separately, while the highest difference in the macroinvertebrate assemblage was observed between the same source distance ranks of different hydroecoregions. Our results showed how the use of both hydroecoregion and source distance should be considered for planning monitoring activities to properly manage rivers and water resources.

    Full Text Available Understanding population dynamics and regulation is fundamental for predicting establishment and spread of invasive alien species. In addition, the population biology of invasive alien species offers an opportunity to study basic ecological processes. In this context, we investigated reproductive and growth plasticity in the invasive crayfish Procambarus clarkii in Lake Trasimeno (central Italy. In total, 3153 crayfish were collected monthly from June 2007 to July 2009. The molt status was assessed by evaluating the exoskeleton hardness. To assess the reproductive cycle, the gonado-somatic and wet hepato-somatic indices were calculated for females. The reproductive status of males was appraised as well. We estimated growth and longevity using the von Bertalanffy growth function, and calculated the total, natural and fishing mortality indices. We then compared our present data with those obtained from the same population eight years before. Our results indicate some changes in population dynamics and in both molting and reproductive periods since the initial invasion of the shallow lake investigated. Long-term differences in the life history of the Trasimeno population may be the result of selective pressures different from those of the native range, but may also result from colonization events and human interference caused by professional fishing activities.

    Full Text Available Abstract The paper presents a study regarding the aggregations of the Lesser Horseshoe bat Rhinolophus hipposideros in Latium, Central Italy, based on data collected during 27 years in natural caves (limestone and artificial buildings (abandoned mines, ancient monuments and others. Furthermore some parameters including size, dynamics, sex ratio and age structures are investigated. The number of bats that occur at the hibernacula in winter is low over the whole territory of this region, the most numerous aggregations being 18 individual bats with an average of about 4 bats/visit. In the shelters of the area, the highest numbers of R. hipposideros, a stenotherm thermophilous species, is reached at the end of January, while at the beginning of spring (April few bats are generally observed. As in many other European populations, males are more commonly represented in winter samples; some caves harbour only adult males over a long time span, about 20 years. The results would suggest that some conservation measures should be introduced to protect this widespread but uncommon and threatened species.

    Full Text Available The paleomagnetism of the Plio-Pleistocene continental sediments cropping out at the north-eastern edge of the Fucino extensionaI basin (Italy, Central Apennines was investigated. The area is characterized by strong neo-tectonic activity and the original purpose was to investigate possibIe verticaI axis rotations in Plio-Pleisto- cene sediments, in order to improve the understanding of the recent geodynamic processes. Scarcity of suit- able outcrops limited sampling at 8 sites (83 specimens from the north-eastern edge of the basin, in clay-rich intervals beIonging to two different sedimentary cycIes. The paleomagnetic resuIts pointed out a peculiar mag- netic behaviour common to the whole set of studied samples. The Natural Remanent Magnetization (NRM is dominated by a vigcous normal component acquired under the influence of the present geomagnetic field, stable only below 200°C. Another (reverse very weak component, stable at higher temperatures (up to 400°C, is present in most of the samples. This component can be precisely isolated for only 7 specimens from 3 different sites and therefore the information gained is not statistically sufficient for any tectonic reconstruction. Rock magnetism analyses showed a variable magnetic mineralogy j but the NRM carriers are not well represented in the artificial remanences produced in the laboratory. Results suggest that the natural viscous remanence is most likeIy carried by coarse multi-domain magnetite.

    2010-05-01

    The work presented here is the continuation of " Sinkhole Project of Latium Region" (2002), carried out by Researchers of the Laboratory of Applied Geology and Hydrogeology of the Department of Geological Sciences of the University "Roma Tre", Rome (Italy), through which were found, in different plain of the whole Region, Sinkhole prone areas, using a methodology based on the superimposition of thematic layers corresponding to geological and anthropogenic breaking factors. In the last years several specific investigations have been conducted by Researchers of the Laboratory in the Pontina Plain, that is located in the south west of the Latium Region, concerning the geological-stratigraphic setting, the sketch of flow in the aquifers located in the Pontine depression, the chemiphysical groundwater characheteristics, the density of wells, the amount of well pumping and piezometric changes. This required the implementation of several piezometric and chemiphysical surveys, the collection and validation of a large number of stratigraphic and geophysical data. All data in the archive have been computerized and the maps vectorized. This makes it possible today to address the analysis with Geographical Information Systems and to start numerical flow simulations, regarding both the heavily drained deep confined aquifer, and the areas subject to the presence of an important water exchange between the recharge area in the Lepini Mountains (carbonatic ridge) and terrigenous aquifers of the plain. Among the main causes that trigger the catastrophic collapses there are, in fact, all the phenomena that cause the mass density reduction through erosion, leaching, dissolution. All these agents are associated with water circulation: flow, velocity, CO2 saturation rate, carbonates saturation rate. The spread in the Pontina plain of deep and high pumping wells, wrongly built without the correct way of progress, and without the realization of cemented portions properly located, can lead

    In foreland thrust belts, abrupt lateral changes in tectonic style, structural-stratigraphic features, and topography usually occur across cross-strike faults. The Central Apennines of Italy offer an exceptional scenario of lateral variations in tectonic setting. Here, the Sangro Volturno oblique thrust ramp (SVOTR) represents the outer thrust front of the Pliocene-Quaternary foreland thrust system, confining southward the axial culmination of the orogen that occurs in the Central Apennines. We present an interpretation of the Pliocene-Quaternary evolution of this cross-strike fault through an integrated dataset including structural-geological mapping and subsurface onshore seismic reflection profiles. The interpretation of the structural framework is augmented by the analysis of low-temperature thermochronometers from 32 new sites extending across the subsurface transverse structure. As evidenced by seismic line interpretation, the localization and development of the SVOTR have been influenced by inherited extensional faults within a positive inversion tectonics context. The regional distribution of the maximum paleotemperature values across the SVOTR constrains the original extent of the allochthonous thrust sheet over all its hanging-wall and footwall blocks. The Pliocene-Quaternary thrusting and inversion of SVOTR caused the strong hanging-wall uplift, which brought to the complete erosion of the allochthonous units and the exhumation of the Adria units. The integrated analysis of low-temperature thermochronometers and structural evidence as applied in the study case can define the role of major cross-strike discontinuities in foreland thrust belts, by constraining and verifying their tectonics inversion significance and the amount of related exhumation.

    Full Text Available Abstract An attempt was made to evaluate the diversity and distribution of cave bats of Latium (Central Italy. Data about twelve species were examined and their frequency have been determined. Only Rhinolophus ferrumequinum and R. hipposideros are really frequent: the other species are more or less localized. The average number of species (2,63 has a great importance for future contro1 of cave bat populations. Similarity between cave bat coenosis was examined, together with the altitude distribution of five species. The relation between altitudinal range, number of caves and average number of species was also studied: between 801 and 1000 m.s.l., the last parameter increases considerably and a hypothesis is presented to explain the phenomenon. This troglophilous bat fauna is probably very rich in species in comparison with other Italian bat communities. Riassunto Viene svolta un'analisi delle cenosi di Chirotteri troglofili dell'Italia Centrale. Vengono esaminati i dati relativi a 12 specie; di ciascuna è stata determinata la frequenza. Rhinolophus ferrumequinum e R. hipposideros risultano le specie più frequenti. I1 numero medio di specie (2,63 assume un importante significato ai fini del controllo delle chirotterofaune troglofile. L'affinità tra le chirotterofaune è stata esaminata, analogamente alla distribuzione altitudinale di cinque specie. Range altitudinale, numero delle cavità e numero medio di specie sono comparati: fra 801 e 1000 m, si osserva un aumento dell'ultimo parametro e vengono formulate ipotesi per spiegare il fenomeno. La ricchezza di specie del Lazio viene evidenziata dal confronto con altre chirotterofaune troglofile regionali italiane.

  6. Some events in Central Italy: are they all tsunamis? A revision for the Italian tsunami catalog

    Full Text Available he catalogs available in the literature show that tsunamis affecting Italian coasts are not very strong, except for a few well analyzed events, i.e. the Messina December 28, 1908 tsunami. This study aims at making a careful revision of some minor tsunamigenic events, in particular those occurred along the coasts of the Central Tyrrhenian Sea, considering tsunamis associated with earthquakes, from 1700 to 1919. These events have been poorly studied so far, and need a check to verify their reliability, even though they are reported in the catalogs. The results show how it is difficult to get a clear definition of those tsunamis, because of a gap in the historical sources, in spite of the large amount of seismological data concerning earthquakes related to the anaIyzed tsunamis. This analysis proposes to delete from the catalog some events for which a clear groundlessness appeared.

  7. Large teleseismic P-wave residuals observed at the Alban Hills volcano, Central Italy

    Full Text Available We collected teleseismic waveforms from a digital microseismic network deployed by the Istituto Nazionale di Geofisica (ING in collaboration with the U.S. Geological Survey (USGS, on the Alban Hills Quaternary volcano during the 1989-1990 seismic swann. About 50 events were recorded by the network, 30 of them by at least 4 stations. We analysed the data in order to image crustal heterogeneities beneath the volcano. The results show large delay time residuals up to - 1 second for stations located on the volcano with respect to station CP9 of the National Seismic Network located about 20 km to the east, on the Apennines. This suggests that the whole area overlies a broad low-velocity region. Although the ray coverage is not very dense, we model the gross seismic structure beneath the volcano by inverting the teleseismic relative residuals with the ACH technique. The main features detected by tbc inversion are a low-velocity zone beneath the southwestern fiank of tbc volcano, and a high-velocity region beneath the center. The depth extension of these anomalous zones ranges between 5 and 16 km. The correspondence between the low-velocity region and the most recent activity of the volcano (- 0.027 Ma leads us to infer the presence of a still hot magmatic body in the crust beneath the southwestern side of the volcano, whereas the central part overlies the older and colder high-velocity volcanic roots related to the previous central activity (0.7 to 0.3 Ma.

    The most frequently employed method for the diagnosis of Angiostrongylus vasorum in dogs is the detection of first stage larvae (L1) in faeces. The sensitivity of coproscopy, however, is limited in case of low parasite load, intermittent larval excretion, and during pre-patency. An epidemiological survey on dogs was conducted applying serological methods in two Italian regions where angiostrongylosis is endemic in foxes. 265 dog serum samples from Tuscany (central Italy - site A) and 447 from Liguria (north-western Italy - site B) were tested with a sandwich-ELISA for detection of circulating antigen, and with an ELISA using A. vasorum adult somatic antigen purified by monoclonal antibodies for specific antibody detection. During previous examinations dogs naturally infected with Leishmania infantum (n=149), Dirofilaria immitis (n=40), Dirofilaria repens (n=30), Acanthocheilonema reconditum (n=27), Crenosoma vulpis (n=1), A. vasorum (n=2), Capillaria aerophila (n=35), Capillaria boehmi (n=3), Toxocara canis (n=68), Toxascaris leonina (n=5), hookworms (n=37) and Trichuris vulpis (n=39) were detected. Sera of these dogs were used to evaluate cross reactions. In site A, 2 dogs (0.8%) were seropositive for antibody and antigen detection and 4 (1.5%) for antibody detection only. From site B, 4 dogs (0.9%) were seropositive for both tests, while other 4 dogs (0.9%) for antigen detection only and 9 dogs (2%) for antibody detection only. Considering a subgroup of 347 dogs from site B which had also been tested with the Baermann technique, 2 (0.6%) were positive for both tests, 4 (1.2%) for antigen detection only and 9 (2.6%) for antibody detection only. The two dogs which were positive for both serological tests were also positive for A. vasorum L1 in the faeces. No significant difference in seropositivities was observed in the group of dogs with other proven parasitic infections. A. vasorum serology presents significant advantages (diagnosis before patency, single serum

    Born from a desire to promote the Italian landscape by integrating its physical aesthetic with its cultural and artistic heritage, we develop a story about the landscape told in popular science, and supported by visual stimulations, poetry and ancient music. Our work proceeds through two different routes. The first route analyzes the landscape from the scientific point of view trying to understand how it evolves and responds in response to changes in independent variables. The second path examines the landscape from a perspective more closely related to the visual and emotional impact that a place evokes, its history, its cultural significance, and perception of its fragility. The latter is perhaps a more complex path, more intimate, which develop fully only through the intersection of different forms of language, linked to specific arts. Three different disciplines focused on the same site, the combination of which results in an emotional experience where the encounter between different languages becomes an expression of the place. Among the many amazing landscapes of Italy, we focus on three known sites from the hystorical region of Montefeltro, in central Italy: "The flatiron of Petrano Mount", "The Stones of Montefeltro", "The sea-cliff of San Bartolo". Since a few years we have created a team of five researchers-artists, called "TerreRare" (Rare Earth Elements), whose mission is the desire to promote the gorgeous Italian landscape. Olivia Nesci, geomorphologist, begins this story analyzing the processes and the "forces" that have created and modified the landscape over time. Laura Valentini, a geologist and a musician, through the musical language, try to reproduce the emotional impact of the site, by searching for a piece of ancient music, composed for harpsichord. The choice of the musical instrument and the historical period is not accidental: the harpsichord has a punchy and gritty tone that clearly expresses the "strength" of the landscape; early music

  14. LCA of domestic and centralized biomass combustion: The case of Lombardy (Italy)

    International Nuclear Information System (INIS)

    This paper analyzes and compares the environmental impacts of biomass combustion in small appliances such as domestic open fireplaces and stoves, and in two types of centralized combined heat and power plants, feeding district heating networks. The analysis is carried out following a Life Cycle Assessment (LCA) approach. The expected savings of GHG (greenhouse gases) emissions due to the substitution of fossil fuels with biomass are quantified, as well as emissions of toxic pollutants and substances responsible for acidification and ozone formation. The LCA results show net savings of GHG emissions when using biomass instead of conventional fuels, varying from 0.08 to 1.08 t of CO2 eq. per t of dry biomass in the different scenarios. Avoided GHG emissions thanks to biomass combustion in Lombardy are 1.32 Mt year-1(1.5% of total regional GHG emissions). For the other impact categories, the use of biomass in district heating systems can again cause a consistent reduction of impacts, whereas biomass combustion in residential devices shows higher impacts than fossil fuels with a particular concern for PAH, VOC and particulate matter emissions. For example, in Lombardy, PM10 emissions from domestic devices are about 8100 t year-1, corresponding to almost one third of the total particulate emissions in 2005. (author)

  15. Mobilisation processes responsible for iron and manganese contamination of groundwater in Central Adriatic Italy.

    Iron and manganese are two of the most common contaminants that exceed the threshold imposed by international and national legislation. When these contamination occurs in groundwater, the use of the water resource is forbidden for any purposes. Several studies investigated these two metals in groundwater, but research focused in the Central Adriatic area are still lacking. Thus, the objective of this study is to identify the origin of Fe and Mn contamination in groundwater and the hydrogeochemical processes that can enrich aquifers with these metals. This work is based on hydrogeochemical and multivariate statistical analysis of analytical results undertaken on soils and groundwater. Fe and Mn contamination are widespread in the alluvial aquifers, and their distribution is regulated by local conditions (i.e. long residence time, presence of peat or organic-rich fine sediments or anthropic pollution) that control redox processes in the aquifers and favour the mobilisation of these two metals in groundwater. The concentration of iron and manganese identified within soil indicates that the latter are a concrete source of the two metals. Anthropic impact on Fe and Mn contamination of groundwater is not related to agricultural activities, but on the contrary, the contribution of hydrocarbons (e.g. spills) is evident. PMID:26948970

    Full Text Available Forests are reckoned essentials as biodiversity reservoirs and carbon sinks. Current threats to forest ecosystems (e.g., climate changes, habitat loss and fragmentation, management changes call for monitoring their biodiversity and preserving their ecological functions. In this study, we characterized plants diversity of five beech forests located in central and north Apennines mountain chain, using results by a probabilistic sampling. In order to achieve our goals, we have considered species richness and abundance, taxonomic distinctness and species composition, using both old and new analytical approaches. Results have shown how: (1 the forest type dominated by Fagus sylvatica is characterized by high complexity, with marked compositional, structural and biodiversity differences; (2 beech forests of Pigelleto di Piancastagnaio and Valle della Corte show the highest plants diversity values. The ecological characteristics of these areas, which sustain high diversity values, are unique and of great conservation interest; (3 the use of species richness as the only diversity measure have not allowed an efficient differentiation between studied areas. Indeed, the use of different indexes and analytical methods is required to detect multiple characteristics of biological diversity, as well as to carry out efficient biodiversity surveys aimed to develop optimal conservation strategies. In the future, we plan to apply the sampling methodology and the analytical approach used in this paper to characterize plants diversity of similar forest types.

    The Grado lagoon is among the largest in the Mediterranean sea and is characterized by salt marshes, where tides influenced the development of a complex micromorphology coupled to a micromosaic of vegetation covers. This study represents the first contribution to the understanding of the main processes governing formation, development and spatial transitions between hydromorphic and subaqueous soils in an Adriatic lagoon ecosystem. Physicochemical characteristics and development of soils were investigated in three salt marshes differing for their proximity to the open sea, textural composition and age of formation. Soils of back barrier salt marshes had A/C profiles and were mostly characterized by a sandy coarse texture that allows rapid drainage and subsurface oxygen exchanges. Soil sequences from the inner salt marsh to its submerged border slope or to a brackish waterhole do not simply represent a hydrosequence, but also reflect erosion/sorting/accumulation processes. The soils in the central part of the lagoon have finer texture and in displayed transition or cambic horizons. Silty clay loam textures and low positions allowed the development of more severe anoxic conditions and accumulation of sulphides. The tide oscillation strongly contributed to formation of redoximorphic features, intensity of anaerobic conditions but also colonization by different plant communities. Discriminant analysis was performed to identify physicochemical properties which discriminate the different soils according to geo-morphological position and prevailing plants. It confirmed that differentiation of plant communities occurred according to distinct morphological and physicochemical soil properties, but also acted as a primary affecting factor of pedogenesis.

    Full Text Available Well-preserved middle and late Hettangian radiolarians have been discovered S-E of Mt. Camicia (Central Apennines in limestone beds that contain also Hettangian ammonites.These beds are part of an Upper Triassic to Lower Jurassic carbonate succession, which crops out in the eastern part of the Gran Sasso range. This succession includes euxinic deposits (bituminous dolostone and other pelagic sediments (mudstone and calcarenites which developed in a basin rimmed by a carbonate platform. In the same time interval, the well-known formations of Dolomia Principale and Calcare Massiccio were forming on this platform.In this paper we examine the radiolarian assemblages collected in three levels of the ammonite bearing beds, and we define two new genera (Squinabolia and Turritus and eight new radiolarian species (Anaticapitula parvireticulata, Anaticapitula triangularis, Farcus aquilensis, Farcus leonseveroi, Parahsuum vraddense, Squinabolia multispinata, Turritus venturii, Zhamoidellum sphaericus, and we define twenty four other species, for a total of thirty eight identified species. The ammonites in the lowest level indicate a middle Hettangian age, those from the two upper levels a late Hettangian.In the Western Tethys successions bearing Hettangian radiolarians are rare and have been found together with ammonites only in the Mt. Camicia section described in this paper. This section permits to correlate the radiolarian assemblages with the ammonite zonation.

    Full Text Available Paleoseismological analyses have been performed in the Central Apennines along faults showing geomorphological evidence of Late Quaternary activity and characterised by the absence of historical seismicity. Three trenches were made along the Mt. Vettore Fault, across a scarp on a Late Pleistocene-Holocene alluvial fan. The youngest displacement event (E1 occurred after 4155-3965 years BP and before the 6th-7th century A.D., a previous event (E2 occurred between 5940-5890/5795-5780 years BP and 4155-3965 years BP, while the oldest event (E3 occurred between 18.000-12.000 years BP and 5940-5890/5795-5780 years BP. One trench was excavated across the Laga Mts. Fault which gave evidence for two displacement events after 8320-8150 years BP. The minimum vertical slip rate estimated through the paleoseismological analysis of the Mt. Vettore Fault is 0.11-0.36 mm/yr, while the minimum slip rate along the Laga Mts. Fault is 0.12 mm/yr. The paleoseismologically inferred recurrence interval is not longer than 4690 years for the Mt. Vettore Fault and not longer than 7570 years for the Laga Mts. Fault, while the minimum elapsed times since the last activation are 1300 and 800 years for the two faults, respectively. The evaluation of the former elapsed time was based on paleoseismological data, while the estimation of the latter was based on the absence of historical earthquakes which may have been caused by the Laga Mts. Fault and on the completeness of the historical catalogues for the large magnitude events in the last eight centuries. Based on the length of the fault at the surface, earthquakes with M 6.5 and 6.6 may be expected from the activation of the Mt. Vettore and Laga Mts. faults, respectively.

    The aim of the research is the characterization of the alpine Upper Valtellina Valley (central Italian Alps, 800 km2) aquifers by means of hydrogeological, hydrogeochemical, As speciation, isotopic and whole-rock analyses. In particular, the main focus of the study was the understanding of the processes responsible for As release and mobilization into the groundwater. Historical chemical data from springs, wells, lakes, rivers and public fountains were collected from the Lombardy Region Health Agency (ASL) and implemented into a geodatabase. The available groundwater chemistry analyses (3050) from five municipalities (Bormio, Livigno, Valdidentro, Valdisotto and Valfurva) cover a relatively long time span between 1996 and 2011. Moreover, samples across the entire study area and covering one full hydrologic year 2012-2013 were collected during four different campaigns (June 2012, October 2012, May 2013, and September 2013) and analyzed . During these campaigns, water samples have been collected from both cold springs and thermal springs. The hydrogeochemistry of aquifers and superficial waters through the hydrologic year, and the long-term regional As distribution and time variability were analyzed. Although the studied springs belong to different catchments with different hydrochemical and lithological conditions, they present some typical characteristics: (1) the water types are dominated by dissolution of the main ions Ca - Mg and SO4-HCO3; (2) the Cl concentration is always very low, and poorly correlated with other ions; (3) the circulation time obtained from isotopic data ranges between 5 and 10 years for thermal springs and it is lower than 2 years for cold springs; (4) the average yearly temperatures (about 12°C for cold springs, and between 18°C and 42° for thermal springs) are nearly constant through the year; (5) dominant oxidizing environments have been observed for most of the cold springs and also for the thermal springs; (6) anthropogenic

    We analyzed the horizontal strain rate field of a sector of the Central-Southern Apennines. This area was a site of large earthquakes in the past, and its present low seismicity could suggest a high seismic hazard. The number of permanent GPS stations is still too limited to provide a satisfactory description of the highly heterogeneous strain field which seems to affect this zone; thus, the use of non continuous but denser GPS networks is still a fundamental tool. We used GPS data collected during yearly repeated campaigns performed from 1994 to 2001 on the GEOMODAP network. Site velocities were obtained starting from the daily coordinates and covariance solutions, using a Kalman filter approach. We used the ITRF2000 solution for European IGS stations to compute an Euler pole and to determine a stable Europe reference frame. The residual velocity field obtained shows two different prevalent motion trends, NNE-ward for the eastern sector of the network and NW-ward for most of the sites of the western side. The mean strain rate tensor obtained from a least square inversion method, over a sub-network oriented approximately SW-NE, shows a significant extensional deformation (1.5x10-8 strain/yr) about normal to the Apennine chain, in agreement with seismological and neotectonic data. On the basis of a network dimension of about 250 Km, this value gives a well constrained estimate of the extensional velocity of about 4.0 mm/yr, normal to the chain axis, that can be considered an upper bound of the active extensio of this area. In order to detect changes in the spatial pattern of the strain rate field within this sub-network we used a least square inversion method that interpolates the velocity solution and solves for the velocity gradient tensor over a regular grid. This analysis shows a more complex picture, with a transition of the strain rate field from about N-S compression in the Tyrrhenian side to about NE-SW extension toward the Adriatic.

    humans, the positivity was 76.47% and these positive specimens came from people with a close contact with pigs. Biomolecular investigations carried out on human and animals amplified positive products revealed 100% homology with the 5.8S rRNA gene of D. fragilis, genotype 1 (e.g., Genbank DQ233451. During a five years research project we demonstrated the presence of D. fragilis in domestic pigs populations as well as in hunted or slaughtered wild boars. Due to the high percentage of positivity we could assume the domestic and/or wild pigs can play a role as natural reservoir of the parasite. In this scenario, outdoor pig farms and/or “confined” wild boars rearing can act as important link of exchange of this parasite. The demonstrated homology of D. fragilis sequences obtained from both humans and animals suggests the potential role of this parasite as zoonotic agent. If an environmentally resistant and infective stage of D. fragilis exists, we suppose the environmental contamination with domestic/wild pigs feces could be as an important factor in the transmission of this parasite to other hosts, including humans.

    Erosion by water is responsible for severe geo-environmental problems in semi-humid to arid Mediterranean areas. Large sectors of Sicily are affected by intense soil erosion phenomena leading to severe damages in agriculture lands that, in some cases, experience high soil loss rates. An important contribution to sediment yield from these areas is given by gully erosion phenomena; the latter, in the last decades, attracted attention of many researches that developed and applied methods to quantify soil loss volumes and to evaluate proneness of territory to this process. The present research aims to assess gully erosion susceptibility in the basin of the San Giorgio torrent, a mountain stream flowing in north-central Sicily and draining an area of about 9.5 km2; the watershed, which is mainly covered by arable lands, has highly erodible slopes characterized by the outcropping of clays and marls. In order to predict gully erosion susceptibility, a multivariate geostatistical approach is adopted here. In particular, the method is based on the definition of spatial relationships between the geographical variability of a set of controlling factors and the occurrence of gullies on slopes; the linear density of gullies computed on homogeneous domains is selected as the probabilistic function expressing how proneness to gully erosion spatially changes in the studied area. Available thematic maps, which were integrated by field and remote surveys, and a high quality DEM, were used to derive eight layers of terrain variables, selected according to geomorphological criteria and expressing both soil erodibility (bedrock lithology, land use) and erosivity of flowing waters (slope angle, Stream Power Index, SL-factor, Topographic Wetness Index, plan and profile curvature). All the parameters were computed for homogeneous spatial domains, created by intersecting a grid of 50m square polygons and a layer of slope units automatically derived from DEM; therefore, the eight layers

    Rivers and effluents have been identified as major pathways for microplastics of terrestrial sources. Moreover, lakes of different dimensions and even in remote locations contain microplastics in striking abundances. This study investigates concentrations of microplastic particles at two lakes in central Italy (Lake Bolsena, Lake Chiusi). A total number of six Manta Trawls have been carried out, two of them one day after heavy winds occurred on Lake Bolsena showing effects on particle distribution of fragments and fibers of varying size categories. Additionally, 36 sediment samples from lakeshores were analyzed for microplastic content. In the surface waters 2.68 to 3.36 particles/m(3) (Lake Chiusi) and 0.82 to 4.42 particles/m(3) (Lake Bolsena) were detected, respectively. Main differences between the lakes are attributed to lake characteristics such as surface and catchment area, depth and the presence of local wind patterns and tide range at Lake Bolsena. An event of heavy winds and moderate rainfall prior to one sampling led to an increase of concentrations at Lake Bolsena which is most probable related to lateral land-based and sewage effluent inputs. The abundances of microplastic particles in sediments vary from mean values of 112 (Lake Bolsena) to 234 particles/kg dry weight (Lake Chiusi). Lake Chiusi results reveal elevated fiber concentrations compared to those of Lake Bolsena what might be a result of higher organic content and a shift in grain size distribution towards the silt and clay fraction at the shallow and highly eutrophic Lake Chiusi. The distribution of particles along different beach levels revealed no significant differences. PMID:27104923

    Full Text Available Thinning is an essential practice in Mediterranean pine forests management but is rarely applied because of the high harvesting costs. The new market of bioenergy products could give a profit to wood biomass harvesting activities, though the drawbacks of elevated supply chain costs, related to technical problems and lack of knowledge about the wood quality have to be overcome in advance. This study analyzed technical, economic, energy and environmental factors of a pine stand thinning in Central Italy, where collected biomass was directed to energy, in order to give a decisional support to reach economical profitability and environmental sustainability in thinning practices. The introduction of Full Tree System maximized the recovery of available biomass, full tree chipping produced material with Heating Value superior than single tree components. The use of a felling frame in motor-manual felling in comparison with the traditional chainsaw reduced operator effort, increasing the number of felled trees per hour, when the stump diameter remained under 15 cm. The energy wood supply chain is not sustainable from an economic point of view, the profitability could be reached only acting on suggested technical levers and particularly reducing costs of hauling operation. The estimation of output/input energy ratio in the supply chain underlined the feasibility of thinning practices for energy. The assessment of CO2 emissions confirmed the environmental sustainability of biomass supply chain in energy when compared to traditional fossil fuels. Study conclusions provide the guidelines for thinning treatment in Mediterranean pine stands, in order to reach environmental and economic sustainability of these practices.

  7. Improving Landslide Forecasting Using ASCAT-Derived Soil Moisture Data: A Case Study of the Torgiovannetto Landslide in Central Italy

    Full Text Available Predicting the spatial and temporal occurrence of rainfall triggered landslides represents an important scientific and operational issue due to the high threat that they pose to human life and property. This study investigates the relationship between rainfall, soil moisture conditions and landslide movement by using recorded movements of a rock slope located in central Italy, the Torgiovannetto landslide. This landslide is a very large rock slide, threatening county and state roads. Data acquired by a network of extensometers and a meteorological station clearly indicate that the movements of the unstable wedge, first detected in 2003, are still proceeding and the alternate phases of quiescence and reactivation are associated with rainfall patterns. By using a multiple linear regression approach, the opening of the tension cracks (as recorded by the extensometers as a function of rainfall and soil moisture conditions prior the occurrence of rainfall, are predicted for the period 2007–2009. Specifically, soil moisture indicators are obtained through the Soil Water Index, SWI, a product derived by the Advanced SCATterometer (ASCAT on board the MetOp (Meteorological Operational satellite and by an Antecedent Precipitation Index, API. Results indicate that the regression performance (in terms of correlation coefficient, r significantly enhances if an indicator of the soil moisture conditions is included. Specifically, r is equal to 0.40 when only rainfall is used as a predictor variable and increases to r = 0.68 and r = 0.85 if the API and the SWI are used respectively. Therefore, the coarse spatial resolution (25 km of satellite data notwithstanding, the ASCAT SWI is found to be very useful for the prediction of landslide movements on a local scale. These findings, although valid for a specific area, present new opportunities for the effective use of satellite-derived soil moisture estimates to improve landslide forecasting.

    We identify geo-morphometric features of active fault scarps in Italy through a semiautomatic processing using GIS. Medium to high resolution DEM was used to characterize the geometry, structural, and erosive elements of two seismogenic normal faults in Central and Southern Apennines. The Pettino fault in L'Aquila area was detected using a 1 m pixel DEM derived from airborne LiDAR survey (Friuli Venezia Giulia Civil Protection). For the Castrovillari fault in northern Calabria region was used a 4 m pixel DEM (Regional Cartography Office of Regione Calabria). Scarp segments are region of planar discontinuities identified by selected values of DEM-derived Terrain Ruggedness Index (TRI) and Vector Ruggedness Measure (VRM). These planar discontinuities corresponds to landscape features such as, river terraces, roads scarps, and other natural or human features. The discrimination between these features have been accomplished overlaying extracted features on aerial photograph, geological and geomorphologic maps and in situ survey. After that, we perform the quantitative and statistical analysis of these areas identified as "fault scarps". The identification of elements relative to the scarps (e.g. base, crest, slope) is then obtained to derive the estimate of parameters describing the fault: altitude, height of the scarp, length, slope and aspect, Terrain Ruggedness Index (TRI) and Vector Ruggedness Measure (VRM). The spatial distribution of the extracted values was obtained through their statistical analysis. We analyze scarp parameters variations along the whole scarp extent, such as strike value from aspect variations, slope and profile curvature differences as indicators of tectonic and/or erosion activity. The combined analysis of the DEM-derived parameters allows us to (a) define aspects of three-dimensional scarp geometry, (b) decipher its geomorphological significance, and (c) estimate the long-term slip rate.

    The results obtained from the spatial analysis of pheromone-baited trap catch data of Lobesia botrana (Denis and Schiffermüller) males are reported. The research was undertaken in the Abruzzo region of central Italy. In the study area, vineyards (of Vitis vinifera L.) are the predominant cultivation, surrounded by hedgerows and small woodlots, and interspersed with cereal crops and olive groves. The main purpose of the study was to investigate the spatio-temporal dynamics of L. botrana, inside and outside vineyards, and to evaluate the effect of the landscape elements on pest distribution. A trend orientation over the experimental area was observed along the direction from northwest to southeast. Correlograms fitted using a spherical model showed in all cases an aggregated distribution and an estimated range having a mean of 174 m in 2005 and 116 m in 2006. Contour maps highlighted that spatial distribution of L. botrana was not limited to vineyards, but its presence is high particularly inside olive groves. The adult distribution on the experimental area changed during the season: hot spots of flight I were positioned inside olive groves; during flights II and III, they were concentrated in vineyards. L. botrana males were also captured in uncultivated fields, but never in high densities. Our results showed that a large proportion of the adult population of L. botrana inhabits areas outside those usually targeted by pest management programs. Thus, in Mediterranean agro-ecosystems, it is highly recommended to consider the whole landscape, with particular attention to olive crops. PMID:18419910

    Full Text Available Within the Cretaceous Period, the Aptian-Albian interval (125–99.6 Ma, Ogg et al., 2008 was a critical time on a global scale. This is evident from 1 changes in the nature of the ocean-climate system brought about by increased ocean crust production coupled with active midplate and plate margin volcanism in a shifting paleogeography (Skelton et al., 2003; 2 cyclic deposition and preservation of common “black shales”, some of them termed Oceanic Anoxic Events(OAE1a to OAE1d (Schlanger and Jenkyns, 1976; Arthur et al., 1990; 3 periodic changes in redox conditions at the ocean bottom (Oceanic Red Beds, ORBs (Wang et al., 2009; and 4 rapid biotic radiations and turnovers (Leckie et al., 2002. The Aptian-Albian time is also of interest for one of the most noteworthy geomagnetic events, namely the post-M0r “Cretaceous Quiet Zone”. This long and constant normal polarity superchron without any convincing true reversal to date (Satolli et al., 2008 precludes usage of reversals magnetostratigraphy from the Aptian through the Santonian. The Poggio le Guaine core was designed to provide a high-resolution age model and a high-resolution relative magnetic paleointensity reference curve for the Aptian-Albian interval of the long normal Cretaceous superchron; it was also designed to understand the causal linkages among geological, biogeochemical, oceanographic and climatic eventsas well as their consequences. The core was drilled at Poggio le Guaine, where the most continuous, complete, and best preserved Aptian-Albian succession is exposed throughout the Umbria-Marche Basin (UMB of the northern Apennines of central Italy (Fig. 1. It represents a continuous record of fossiliferous pelagic rocks extending from the Albian-Cenomanian boundary down to the uppermost Barremian (99.6–126 Ma.

    Full Text Available In this paper, we compare the forecasting performance of several statistical models, which are used to describe the occurrence process of earthquakes in forecasting the short-term earthquake probabilities during the L’Aquila earthquake sequence in central Italy in 2009. These models include the Proximity to Past Earthquakes (PPE model and two versions of the Epidemic Type Aftershock Sequence (ETAS model. We used the information gains corresponding to the Poisson and binomial scores to evaluate the performance of these models. It is shown that both ETAS models work better than the PPE model. However, in comparing the two types of ETAS models, the one with the same fixed exponent coefficient (alpha = 2.3 for both the productivity function and the scaling factor in the spatial response function (ETAS I, performs better in forecasting the active aftershock sequence than the model with different exponent coefficients (ETAS II, when the Poisson score is adopted. ETAS II performs better when a lower magnitude threshold of 2.0 and the binomial score are used. The reason is found to be that the catalog does not have an event of similar magnitude to the L’Aquila mainshock (Mw 6.3 in the training period (April 16, 2005 to March 15, 2009, and the (alpha-value is underestimated, thus the forecast seismicity is underestimated when the productivity function is extrapolated to high magnitudes. We also investigate the effect of the inclusion of small events in forecasting larger events. These results suggest that the training catalog used for estimating the model parameters should include earthquakes of magnitudes similar to the mainshock when forecasting seismicity during an aftershock sequence.

  12. Is 222Rn a suitable tracer of stream–groundwater interactions? A case study in central Italy

    International Nuclear Information System (INIS)

    Highlights: ► Modeling riverbank infiltration in an alluvial plain. ► 222Rn gave information about the river water residence times within the aquifer. ► TDS allowed to estimate the extent of mixing between surface waters and groundwater. ► Stream-bank infiltration velocities are smaller in the high-flow than in the low-flow period. - Abstract: River water infiltration into an unconfined porous aquifer (∼73% gravels, ∼12% sands, ∼15% silts and clays) in the Petrignano d’Assisi plain, central Italy, was traced combining isotopic techniques (222Rn) with hydrochemical and hydrogeologic techniques in order to characterize the system under study. The 222Rn gave information about the river water residence times within the aquifer and hydrochemical data, in a two-component mixing model, which allowed estimating the extent of mixing between surface waters and groundwater in wells at increasing distances from the river. The mixing measured in the well closer to the riverbank indicated a higher contribution of river water (up to 99%) during the groundwater recession phase and a moderate contribution (up to 64%) during the recharge phase. A model describing 222Rn concentrations in groundwater as the result of both parent/daughter nuclide equilibrium and mixing process (222Rn mixing/saturation model) was used to describe observed Rn concentrations and mixing index trends with the aim of evaluating water mean infiltration velocities along the transect. The stream bank infiltration velocities obtained by the model ranged from 1 m day−1 during groundwater recharge periods, when river water infiltration is lower, to 39 m day−1 during recession phases, when river water infiltration is larger

    The Samnites were an Iron Age population that shifted from warlike mountain dwellers to the largest sociopolitical unit of central Italy, able to dispute with Rome the domination over the peninsula. Archaeological and historical evidence suggests that this major shift in the scale of conflict may have involved a reorganization of the military system, which changed from an elite militia to a conscript or standing army from the Orientalizing-Archaic (800-500 BC) to Hellenistic times (400-27 BC). We propose a bioarchaeological framework jointly analyzing skeletal properties and funerary treatment in male Samnites to investigate on this shift in military organization. We anticipated that, when Samnites had an elite militia, the warring force was constituted by the wealthier segments of the society. Conversely, we expected the warring force of the standing/conscript army to be mainly drawn from the lower social strata. We considered high asymmetry in J, a measure of humeral torsional rigidity (calculated via cross-sectional geometry, CSG) as a proxy for pre- and peri-adolescent-onset weapon training. The social standing of the individual was approximated via funerary treatment analysis (Status Index). Results show that in the Orientalizing-Archaic period, humeral asymmetry and Status Index are positively correlated, and the high-status subsample shows significantly higher asymmetry than the low-status subsample. Among Hellenistic Samnites, no correlation between Status Index and humeral asymmetry is present, and the low-status subsample is the most lateralized. Results support the use of CSG in a strong theoretical framework to investigate past changes in military organization and their correlates in terms of sociopolitical development, alterations of power relationships, and warfare.

  14. 222Rn and CO2 soil-gas geochemical characterization of thermally altered clays at Orciatico (Tuscany, Central Italy)

    International Nuclear Information System (INIS)

    Research highlights: → Soil-gas technique is applied to study gas permeability of Orciatico clay units. → Clay permeability depends on thermal and mechanical alteration degree. → Soil-gas distributions are due to shallow fracturing of clays. → Rn and CO2 soil-gas anomalies highlight secondary permeability in clay sequence. → Soil-gas results are supported by detailed geoelectrical surveys. - Abstract: The physical properties of clay allow argillaceous formations to be considered geological barriers to radionuclide migration in high-level radioactive-waste isolation systems. As laboratory simulations are short term and numerical models always involve assumptions and simplifications of the natural system, natural analogues are extremely attractive surrogates for the study of long-term isolation. The clays of the Orciatico area (Tuscany, Central Italy), which were thermally altered via the intrusion of an alkali-trachyte laccolith, represent an interesting natural model of a heat source which acted on argillaceous materials. The study of this natural analogue was performed through detailed geoelectrical and soil-gas surveys to define both the geometry of the intrusive body and the gas permeability of a clay unit characterized by different degrees of thermal alteration. The results of this study show that gas permeability is increased in the clay sequences subjected to greater heat input from the emplacement of the Orciatico intrusion, despite the lack of apparent mineral and geotechnical variations. These results, which take into consideration long time periods in a natural, large-scale geological system, may have important implications for the long-term safety of underground storage of nuclear waste in clay formations.

    Soil organic matter (SOM) content is one of the main factors to be considered in the evaluation of soil health and fertility.As timing,human and monetary resources often limit the amount of available data,geostatistical techniques provide a valid scientific approach to cope with spatial variability,to interpolate existing data and to predict values at unsampled locations for accurate SOM status survey.Using geostatistical and geographic information system (GIS) approaches,the spatial variability of some physical and chemical soil parameters was investigated under Mediterranean climatic condition in the Abruzzo region of central Italy,where soil erosion processes accelerated by human induced factors are the main causes of soil degradation associated with low SOM content.Experimental semivariograms were established to determine the spatial dependence of the soil variables under investigation.The results of 250 soil sampling point data were interpolated by means of ordinary kriging coupled with a GIS to produce contour maps distribution of soil texture,SOM content related to texture,and C/N ratio.The resulting spatial interpolation of the dataset highlighted a low content of SOM in relation with soil texture in most of the surveyed area (87%) and an optimal C/N ratio for only half of the investigated surface area.Spatial location of degraded area and the assessment of its magnitude can provide decision makers with an accurate support to design appropriate soil conservation strategies and then facilitate a regional planning of agri-environmental measures in the framework of the European Common Agricultural Policy.

    We investigate a portion of the ancient (VI and IV centuries BC) polygonal walls of Amelia, in Central Italy. After the collapse of a portion of the walls which occurred in January 2006, a wide project started in order to monitor their external facade and inspect the characteristics of the internal structure, currently not clearly known. In this specific case, the preservation of such an important cultural heritage was mandatory, therefore invasive methods like drilling or archaeological essays cannot be used. For this purpose, a multidisciplinary approach represents an innovative way to shed light on their inner structure. We combine several non-invasive techniques such as Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT), specifically adapted for this study, Laser Scanning and Digital Terrestrial Photogrammetry, integrated with other geomatic measures provided by a Total Station and Global Navigation Satellite Systems (GNSS). After collecting some historical information, we gather the whole datasets exploring for their integration an interpretation approach borrowed from the reflection seismic (attribute analysis and three dimensional visualization). The results give rise for the first time to the internal imaging of this ancient walls, highlighting features associable to different building styles related to different historical periods. Among the result, we define a max wall thickness of about 3.5 m for the cyclopic sector, we show details of the internal block organization and we detect low resistivity values interpretable with high water content behind the basal part of the walls. Then, quantitative analyses to assess their reliable geotechnical stability are done, integrating new geometrical constrains provided by the geophysics and geo-technical ground parameters available in literature. From this analysis, we highlight how the Amelia walls are interested, in the investigated sector, by a critical pseudo-static equilibrium.

    Sinkholes and other karst structures in settled carbonate lands can be a significant source of hazard for humans and human works. Acque Albule, the study area of this work, is a Plio-Pleistocene basin near Rome, central Italy, superficially filled by a large and thick deposit of late Pleistocene thermogene travertine. Human activities blanket large portions of the flat territory covering most evidence from geological surface processes and potentially inducing scientists and public officials to underestimate some natural hazards including those connected with sinkholes. To contribute to the proper assessment of these hazards, a geomorphologic study of the basin was performed using digital elevation models (DEMs), recent aerial photographs, and field surveys. Historical material such as old aerial photographs and past geomorphologic studies both pre-dating the most part of quarrying and village building was also used together with memories of the elderly population. This preliminary study pointed out the presence of numerous potentially active sinkholes that are at present largely masked by either quarrying or overbuilding. Where this first study pointed out the apparent absence of sinkholes in areas characterized by high density of buildings, a detailed subsurface study was performed using properly-calibrated electrical resistivity tomography (ERT) and dynamic penetration measurements (DPSH), together with some borehole logs made available from the local municipality. This second study highlighted the presence of sinkholes and caves that are, this time, substantially hidden to the resolution of standard methods and materials such as aerial photographs, DEMs, and field surveys. Active sinkhole subsidence in the Acque Albule Basin may explain, at least in part, the frequent damages that affect numerous buildings in the area. The main conclusion from this study is that the mitigation of sinkhole hazard in highly populated areas has to pass through a thorough search of

    This work illustrates the studies carried out on a complex landslide phenomenon between the Sangro and Osento River's mouths, near Torino di Sangro village in Southern Abruzzo Region (Italy). Historical activity of this landslide is well-documented since 1916; the activation/reactivation of the movements caused several interruptions of a national railway and the damage of few houses. The Torino di Sangro case study can be regarded as representative of many large landslides distributed along the central Adriatic coast (e.g., Ancona, Ortona, Vasto and Petacciato Landslides) that affect densely populated urban areas with a large amount of man-made infrastructure. The main controlling factors of these large and deep-seated landslides are still debated. From the geological and geomorphological viewpoint, the central Adriatic coast is characterized by a low-relief landscape (mesa) carved on clay-sandstone-conglomerate bedrock belonging to the Upper Pliocene - Lower Pleistocene marine deposits and locally to the Middle Pleistocene marine to continental transitional deposits. This high coast is widely affected by slope instability (rock falls, rotational, complex and shallow landslides) on both active and inactive sea cliffs, the first being mainly affected by wave-cut erosion and the latter influenced by heavy rainfall and changes of pore pressure. The main landslide has the typical characteristics of a deep-seated gravitation deformation. The landslide study was based on a multidisciplinary approach including: 1) definition and GIS mapping of geology and geomorphology factors (slope, aspect, topographic curvature, bedrock lithology, near-surface deposits, deposit thickness and land use), by means of DTM processing, multi-temporal analysis, and large-scale geomorphological field survey; 2) monitoring system in the landslide; 3) application of empiric models for the analysis of unstable sandstone-conglomerate escarpments; 4) slope stability analysis performed using a

  1. Modelling radionuclide behaviour in deep lakes of the Italian Alpine region: Seasonality effects and comparison with deep volcanic lakes of Central Italy

    International Nuclear Information System (INIS)

    The present report describes the results of research carried out following the Chernobyl accident to analyse the behaviour of radionuclides in some Italian lakes. The following lacustrine systems were examined: volcanic lakes Bolsena, Bracciano and Vico (central Italy) and lake Como (north Italy) whose drainage area is located in the Alpine region. The average residence times of 137Cs in water of volcanic lakes are much higher than the radionuclide residence time in lake Como. As quantitative analyses can show, the differences between the mean water retention times of the examined lakes do not suffice to explain this occurrence. Some peculiar seasonal effects (thermal stratification of water and ice/snow melting in lake drainage area) and high sedimentation rates are responsible of 137Cs efficient removal from water of lake Como

    Full Text Available The barbastelle bat, Barbastella barbastellus (Schreber, 1774 is a medium-sized, tree-dwelling vespertilionid classified as ?Endangered? in Italy; in western Europe it may be one of the rarest bat species. B. barbastellus shows roosting preferences that should be regarded as a key point in conservation protocols. We examined roost selection in a breeding population of B. barbastellus from the Abruzzo Lazio and Molise National Park (central Italy at three levels: woodland structure and management type; tree characteristics; and cavity characteristics. In 2001-2002, we fitted 31 adult B. barbastellus (29 lactating females, one pregnant female and one male with 0.48g radio-tags and tracked them to their roost-trees. The bats were tracked for 4.5 ± 3.7 days (range: 0-12 days. We located 33 roosts used by 25 subjects (1.8±1.2 roosts/bat, range 1-5. The bats switched roosts frequently: 13 bats used more than one tree over the study period. A chi-square analysis showed that the roosts were not distributed at random across woodland categories: unmanaged woodland was positively selected, whereas shelterwood-harvested woodland was used in proportion to its availability, and ?pastures+scattered trees? was avoided. Twenty out of 33 roost trees were dead Fagus sylvatica trees; conversely, living F. sylvatica dominated in a tree sample obtained at random; dead trees were used more than expected (Χ² test, P <0.001. Overall, roost trees were significantly taller and had a larger diameter at breast?s height and more cavities than random trees; they also had a lower percent canopy closure than random trees. To highlight which variables were actually associated with selection, we devised a logistic regression model. The full model was significant (P <0.001; removal of tree type and tree height affected the model significantly, but the other variables did not produce detectable effects. The

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

    The Samnite bronze belts and the chest disk cuirasses (VIII-IV BC) are the distinctive defensive weapons of the Samnite warriors having likely also a symbolic relevance. These artefacts were mainly found during the archaeological excavations of warriors' graves from ancient Abruzzo (central Italy). Their chemical composition, metallurgical features and corrosion products formed during the long-term burial have been studied by means of the combined use of analytical techniques such as optical microscopy (OM), scanning electron microscopy coupled with energy-dispersive X-ray micro-analysis (SEM-EDS), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The micro-chemical and structural results show that the bronze belts have often been produced by using unusual high-tin bronze alloys achieving a silver-like appearance and by performing tailored cycles of thermal treatments under reducing conditions and hot mechanical working aimed to shape the high-tin alloys in the form of a thin bronze sheet. Furthermore, the investigation has shown that the main alloying elements have been transformed during the burial into mineral species giving rise to the formation of stratified structures constituted by different mineral phases such as tin oxides, cuprous oxide (Cu2O) and copper carbonates (azurite (Cu3(CO3)2(OH)2 and malachite (CuCO3Cu(OH)2)) as well as dangerous chlorine-based compounds such as nantokite (CuCl) and atacamite (Cu2(OH)3Cl) polymorphs. This information evidences the strict interaction of the alloying elements with the soil components as well as the occurrence of the copper cyclic corrosion as a post-burial degradation phenomenon. The present study confirms that the combined micro-chemical and micro-structural investigation techniques such as SEM-EDS, XPS, XRD and OM can be successfully used to investigate the technological production processes of the ancient artefacts and to achieve the detailed micro-chemical and structural description of the

    Following the Mw 6.3 L'Aquila Earthquake of 6th April, 2009, the Colle di Roio village, central Italy, suffered severe building damages. The village is located on top of an elongated carbonate ridge characterized by a complex subsurface structure, a condition prone to seismic amplification due to topographic and stratigraphic effects. We address the role of the subsurface structure and topography in the ground-motion amplification observed at the ridge top. To characterize the subsurface structure of the ridge we performed geological investigations and ambient vibration measurements in single-station as well as 2D-array configuration. Geological investigations pointed out that the ridge top is characterized by the presence of fractured rock material as a consequence of its anticlinal fold structure. Horizontal-to-vertical spectral ratio processing of ambient vibration records (HVSR) showed a broad peak in the HVSR functions in the frequency range 4-6 Hz and 2D-array data demonstrated that locally the subsurface structure at the ridge top cannot be considered homogeneous. In summer 2009, we further installed one accelerometric station on the ridge top to experimentally evaluate the site amplification. By means of Horizontal-to-Vertical spectral ratio analysis of a sample of 18 weak-motion records (H/V), we found that ground-motion amplification occurs in a narrow frequency range centred around 4 Hz with mean ratio amplitude of 6. We also analysed the dependence of seismic amplification on the azimuth by calculating H/V ratios for horizontal components rotated into a range of azimuths. This analysis showed that the higher level of horizontal amplification occurs in the direction perpendicular to the ridge trending direction. With the aim of evaluating the contribution of the topography and the local subsurface structure on the observed seismic amplification, we performed 2D finite difference modelling of wave propagation through the ridge, adopting both homogeneous

The lowest value of the factor of safety is stored for each raster cell together with the depth of the associated slip surface. This results in an overview of potentially unstable regions without showing the individual sliding areas. We test the model in the Collazzone area, Umbria, Central Italy, which is susceptible to landslides of different types. The presence of both shallow translational and deep-seated rotational landslides, and the availability of reference data, allow for the critical evaluation of the model in comparison with standard infinite slope stability models.

    In November and December 2013, the Marche region (Central Italy) was hit by three severe, but not rare, meteorological events. The maximum value of the three days cumulative rainfall (499 mm) was recorded at the rain gauge of Pintura di Bolognola. The intense rainfall caused floods along the rivers and triggered numerous landslides, mostly located in the hilly and mountainous terrain of the region. The territory is crossed by a large number of roads connecting small rural settlements. After the events, the Regional Civil Protection Office requested to the Research Institute for the geo-hydrological Protection (IRPI-CNR) a technical support to evaluate the hazard condition for different sites affected by landslides. For an area of approximately 200 km2, in the Municipalities of Acquasanta Terme and Roccafluvione, field surveys were carried out to identify the rainfall-induced landslides and to produce an event inventory map. More than 1,500 slope failures were mapped including earth flows, slide-earth flows, slides, rock-falls and complex slides. Field surveys were focused also to estimate qualitatively damages along the roads. Roads were classified in two classes: the main roads under the State responsibility and the secondary roads under the Municipality responsibility. The different types of damage were classified in three classes: i) aesthetic (minor), where the road functionality was not compromised; ii) functional (medium), where the functionality was compromised and iii) structural (severe) where roads are severely or completely damaged. Immediately after the event, the technicians of the Municipalities of Acquasanta Terme and Roccafluvione spent major efforts to partially restore the functionality of the secondary roads in order to guarantee the primary human needs. In the following ten days, they compiled a list of interventions, associated with the relative direct costs, aimed to the total restoration of the roads functionality. In collaboration with the

    Full Text Available The present paper is the third in the series and concludes the revision of the Pliocene naticids of northern and central Italy. It expands to 31 the total number of species and subspecies of this family recovered so far from the Pliocene deposits of the investigated area. Of the thirteen taxa covered in this study, eight (bononiensis, exturbinoides, grossularia, guillemini, helicina helicina, magenesi, notabilis and pulchella belong to the genus Euspira Agassiz in J. Sowerby, 1837, one (olla belongs to the genus Neverita Risso, 1826, two others (fasciolata and intricata are members of Payraudeautia Bucquoy, Dautzenberg & Dollfus, 1883, and the last two (perregulare and striatum belong to the genus Sinum Röding, 1798. All thirteen taxa considered in this paper are described and commented on in the systematic account. Since species herein recorded under Euspira were often assigned to Polinices Montfort, 1810 by earlier workers, both genera are discussed and their characters are defined on the basis of their respective type species. A significant output is that the tropical genus Polinices, well represented in Late Oligocene and Miocene naticid assemblages of Europe, disappeared from that area and there are no reliable records of it subsequent to the Tortonian. Also the relations between Polinices and Neverita are discussed and their respective distinguishing characters are pointed out.This study demonstrates that the taxonomic relevance of a particular character may change greatly depending on the subfamily considered, and cannot be extended to Naticidae as a whole. Naticine species are confidently identifiable primarily by characters of their opercula. These latter can be combined with protoconch characters and color patterns, umbilical callus and umbilical characters in descending order of importance. Poliniceine and sinine species are readily and univocally distinguished by a combination of protoconch and umbilical characters, the larval shell

Kathy was one of five people in 1999 to be awarded an IOP Public Awareness of Physics award. Dr Kathy Sykes What attracted you to Physics in the first place? It was really when I discovered that Physics was all about making models of the world, because then suddenly the ability to be creative became important. I liked the idea that you could have a picture of the world that might work quite well but you could always replace that with a better one. That was what made science come alive and make it seem like something that I'd really love to be involved in, rather than science as a stale body of facts that I needed to learn. I was much more interested in ideas than in facts. I think that finding out about 'models' happened around the time I was discovering quantum mechanics and how the act of observing something can actually affect the outcome. I found it incredibly exciting - especially how that changed the whole philosophy of science. I also had a fantastic teacher in physics and I owe an awful lot to him. He just swooped in at the last moment when I was considering giving it up so that made an enormous difference. After my degree I went to teach maths and physics A-level in Zimbabwe with the VSO, and it was partly wanting to share my excitement with other people about physics that made me want to go and teach abroad. When I came back and began my PhD in Physics at Bristol University, I missed teaching and thought it was important to get the public more involved in science and debates about science. My supervisor, Pete Barham, was doing lots of this himself, and he helped and encouraged me enormously. I can't thank him enough. Did you consider teaching as a career? Well I like having the carpet whipped away from

    The study investigated the nature of self-reported morbidity and determinants of health status among people living with HIV/AIDS (PLWHA) in North Central Nigeria. A multi-stage cluster sampling method was used to select 1,056 adult PLWHA from 60 community-based support groups as respondents to a structured questionnaire. Based on health production function, health status was specified as a function of individual/household characteristics, health-related behaviours and genetic endowment. Descriptive statistics showed that more than half (52.8%, n=558) of the PLWHA reported illness in the last four weeks. The poor, widows and divorcees, and those living in rural areas reported illness more than their non-poor, married and urban counterparts. Logistic regression results indicated that self reported mobility was associated with rural residence (p=.005), greater use of condom (p=.013), and lower CD4 count (p=.007). Programs to promote positive living and access to health care services among PLWHA in Nigeria, especially in rural areas, are recommended. PMID:23377732

    ASE: Attend, Socialize, Enjoy Bob Kibble reflects on the enriching effects of the annual meeting Bob Kibble is a teacher trainer at the University of Edinburgh, Scotland. I remember my first ASE meeting in Reading. Perhaps in 1978 or thereabouts. I had been teaching for a few years and thought I'd check out this local convention of science teachers. It was indeed a revelation that so many people had so much to say about teaching science. There was talk about N and F levels and the 'I level grill'. Someone had ordered something called a BBC machine (later revealed to me as the latest in hi-tech teaching). I remember it well. But it was a lonely affair for a recent recruit. People seemed to know each other and there was much friendly exchanging. However, nobody knew me and I knew nobody else. The professional revelations were accompanied by a personal isolation. A strange set of memories indeed for a new recruit, unskilled and clumsy in the social arena. Bob practising for the ASE singalong session this year. This year I went to the ASE Centenary meeting in Guildford, my sixteenth ASE annual meeting. Things have changed since the early days. Thursday started with a formal Cathedral service in celebration of 100 years of the ASE. I sat next to a lady from Oxford and behind my good friend Dave from Croydon. Things snowballed from there. I went to a workshop on the water cycle and was brought face to face with my own misconceptions about the life story of a water molecule. Got a freebie coloured bracelet as well. Thanks Margaret. A chap from Bournemouth gave me loads of ideas about how best to set up a shared lesson observation scheme as well as how to run a professional development workshop. Thanks Stuart.

For the public galleries of the NHM my group provides expert input to exhibitions-when the meteorite pavilion was recently refurbished we suggested a layout, wrote text and selected samples, but this was then 'edited' by the exhibition designers. I'm also working on a new website with virtual meteorite specimens. As an expert on Martian meteorites I often get interviewed by the media: for example, I am on a new Channel 4 programme called Destination Mars. I have also just finished a general interest book—it's called Search for Life; the NHM have just published it (in March). And do you get to go to exciting places? As a researcher I go to conferences I am just off to the States this week. I went to Antarctica ten years ago meteorite collecting and I am hoping to go to Australia this year. It is good fun but they really do need an expert who can recognise a meteorite. I'll be going to the Nullarbor region of Australia for 2 3 weeks depending on the weather if it's too green there is too much grass, so you can't see the meteorites. How do you find people respond to meteorites? People love touching rocks from outer space, especially primary school children. You can see how they are burnt on the outside. When you feel the weight of them it really brings it home: iron meteorites are heavy! They'll often say 'Wow, it fell from the sky' as they glance upwards, half expecting another one to come crashing through the ceiling. Everyone finds it amazing that a solid object has come as if from nowhere. And they are so old. They can't believe how old they are. We want to know where we come from. There is always lots of media coverage about what is happening in the sky (eclipses and the like). It's there and it's a bit of a mystery. If we can get to grips with how our planets and how our own Sun formed it can put us in the picture as to where we have come from and

  19. Asbestos exposure during quarrying and processing of serpentinites: a case study in Valmalenco, Central Alps, Northern Italy

    2012-04-01

    Serpentinites are metamorphic rocks derived from ultramafics such as peridotites (lherzolites and/or harzburgites), with a typical mineralogical assemblage of antigorite, olivine, diopside and minor magnetite, chlorite and chrysotile. If the rock mass has good geotechnical properties, these stones are quarried because of their wide variety of green shades and outstanding technical properties. Excellent stones are produced in the Malenco Valley, Central Alps (northern Italy, Sondrio): here the geological set-up is dominated by the ultramafic Malenco massif (lower crust-mantle complex), exposed at the Penninic to Austroalpine boundary zone. Different processing operations give origin to valuable products like stoves, funeral monuments, design home appliances; important building element as roof slabs, tiles for floor and wall coverings constitute the main commercial line of production. In this area, good quality long fibre chrysotile asbestos was mined since the XIX century, till the seventies. The asbestos fissures (mostly slip-fiber) are well known in Valmalenco, associated to an important ENE-WSW striking fracture and hydrothermal vein system. Some actual serpentinite quarries "cross" at times tunnels of the old asbestos mines, because the fracture and vein system "guides" the extraction. At present time, this area represents an excellent example of naturally occurring asbestos (NOA). For these reasons, workers' exposure to asbestos during quarrying and processing cannot be ruled out, and must be assessed according to national laws. From 2004 to nowadays, the INAIL Regional Management of Lombardia, with the collaboration of University of Milan-Bicocca, carried out extensive monitoring campaigns both in quarries and in processing laboratories. More than 300 massive samples (rocks and veins) and 250 airborne dust samples were collected during the surveys. One of the main problems in the study of massive serpentinites is the accurate identification of the different

    Following laws and regulations concerning extreme natural events management, the Italian national hydrometeorological early warning system is composed by 21 regional offices (Functional Centres - CF). Umbria Region CF is located in Central Italy and provides early warning, monitoring and decision support systems (DSS) when significant flood/landslide events occur. The alert system is based on hydrometric and rainfall thresholds with detailed procedures for the management of critical events in which different roles of authorities and institutions involved are defined. For the real time flood forecasting system, at the CF several operational hydrological and hydraulic models were developed and implemented for a "dynamic" hazard/risk scenario assessment for Civil Protection DSS, useful also for the development of Flood Risk Management Plans according to the European "Floods Directive" 2007/60. In the period 11th-14th November 2012, a significant flood event occurred in Umbria (as well as Tuscany and northern Lazio). The territory was interested by intense and persistent rainfall; the hydro-meteorological monitoring network recorded locally rainfall depth over 300 mm in 72 hours and, generally, values greater than the seasonal averages all over the region. In the most affected area the recorded rainfall depths correspond to centenarian return period: one-third of the annual mean precipitation occurred in 2-3 days. Almost all rivers in Umbria have been involved, exceeding hydrometric thresholds, and several ones overflowed. Furthermore, in some cases, so high water levels have never been recorded by the hydrometric network. As in the major flood events occurred in the last years, dams (Montedoglio and Corbara dams along Tiber River and Casanuova dam along Chiascio River) and other hydraulic works for flood defense (e.g. along Chiani stream) played a very important mitigation role, storing high water volumes and avoiding the overlap of peak discharges downstream.

    Palaeomagnetic data from sedimentary and lava rocks provide a unique opportunity to investigate the details of geomagnetic field behaviour during field reversals, as well as experimental evidence to constrain predictions of geomagnetic field evolution during periods of field instability. The sedimentary infill in the intermountain Sulmona basin, central Italy, includes a continuous succession of lacustrine sediments that spans the last full geomagnetic field reversal, the Matuyama-Brunhes boundary (MBB). The succession consists of biogenic carbonates and contains several distal tephra layers from volcanic eruptions that occurred along the Tyrrhenian margin of the Italian peninsula, which provide the means for high-resolution 40Ar/39Ar dating. The stratigraphic interval spanning the MBB shows good paleomagnetic properties, with easily interpretable demagnetization behavior allowing for straightforward identification of a characteristic remanent magnetization that is carried by magnetite (likely biogenic). It is therefore particularly suitable for investigating the MMB and for precisely assessing the tempo of the magnetic directional change. With an initial high-resolution paleomagnetic study of the Sulmona section (Sagnotti et al., 2014, Geophys. J. Int., 199, 1110-1124) we showed that the field reversal at the terminus of the MBB was extremely sharp and occurred in less than a century about 786 ka ago. In this section, such a sharp transition is recorded 2-3 cm below a faint cryptotephra (named SUL2-18). We also recognized that thin (4-6 cm) intervals above major tephra layers (SUL2-19 and SUL2-20) located ˜25 and ˜35 cm below the polarity flip were most likely remagnetized during the Brunhes Chron. With the aim of improving the temporal resolution of the first reported Sulmona MBB record and understanding the possible influence of SUL2-18 cryptotephra on the paleomagnetic record, we did a second study (Sagnotti et al., 2016, Geophys. J. Int., 204, 798-812) with

    We analyzed the Bouguer gravity anomaly signal beneath the Mt. Amiata area in order to reconstruct the subsurface setting. The study area is characterized by a pronounced gravity minimum, possibly correlated with the observed anomalous heat flow and hydrothermal activity. Using different approaches, previous authors defined a low density body (generally interpreted as a magmatic intrusion) beneath this area, which could explain the observed gravity anomaly minimum. However the proposed geologic models show different geometries and densities for the batholith. The gravity data used in this study (kindly provided by eni) were acquired from different institutions (eni, OGS, USDMA and Servizio Geologico d'Italia) and collected in a unique dataset, consisting of about 50000 stations, randomly distributed, which cover Central Italy, with a spacing of less than 1 km. For each station the elevation and the Bouguer gravity anomaly data are given. From this dataset, we created two maps of the Bouguer gravity anomaly and the topography, using the Minimum Curvature gridding method considering a grid cell size of 500m x 500m. The Bouguer gravity anomaly has been computed using a density of 2.67 g/cm3. From these maps we extracted a window of about 240 km2 (12x20 km) for the study area, which includes the Mt. Amiata region and the adjacent Radicofani sedimentary basin. The first part of this study was focused on calculating the first order vertical derivative and the power spectra analysis of the Bouguer gravity anomaly to enhance the effect of shallow bodies and estimating the source depth respectively. The second part of this study was focused on constructing a 3D geological density model of the subsurface setting of the studied area, implementing a forward modelling approach. The stratigraphy of the study area's upper crust schematically consists of six litho-mechanical units, whose density was derived from velocity data collected by active seismic surveys. A preliminary

    the war Hoyle returned to Cambridge, but kept in close contact with his collaborators. Fred Hoyle was a canny and media-savvy scientist, 40 years before such things were recognized. Martin Rees said after his death '[He] also had other dimensions to his career, his inventiveness and skill as a communicator'. It is hard to realize now the impact that Hoyle's broadcasts had in post-war Britain. His programmes for the BBC on The Nature of the Universe won greater audiences than such unlikely rivals as Bertrand Russell and Tommy Handley. Even today many people recall how they were affected by listening to these broadcasts. Hoyle used one of his broadcasts to ridicule the hot explosion theory. He referred to the idea of a 'big bang as fanciful'. Unfortunately the name stuck, much to Hoyle's chagrin. In the 1950s Hoyle began a fruitful collaboration with Willy Fowler of the California Institute of Technology in Pasadena. Hoyle was interested in the origin of the chemical elements. Hans Bethe, Charles Critchfield and Karl-Frederich von Weizsäcker had calculated in 1939 how stars could turn protons into helium nuclei by nuclear fusion. Part of the Vela supernova remmant, the debris left after the type of massive explosion in which Hoyle predicted that heavy nuclei were formed. (© Royal Observatory, Edinburgh, Anglo-Australian Observatory.) Building on earlier collaboration with Ed Saltpeter, Hoyle used data supplied by Geoffrey and Margaret Burbidge and, working with Fowler, began to piece together how the elements were formed. By looking at very large stars near the end of their lives and examining their chemical composition, they noticed that the abundances of elements almost exactly corresponded to those with a low nuclear capture cross section.

    Altered sleep is a common and central symptom of post-traumatic stress disorder (PTSD). In fact, sleep disturbances are included in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnostic criteria for PTSD. However, it has been hypothesized that sleep disturbances are crucially involved in the aetiology of PTSD, rather than being solely a symptom arising secondarily from this disorder. Therefore, knowing the long-term effects of a trauma can be essential to establish the need of specific interventions for the prevention and treatment of mental disorders that may persist years after a traumatic experience. In one study we showed, for the first time, that even after a period of two years people exposed to a catastrophic disaster such as the L'Aquila earthquake continue to suffer from a reduced sleep quality. Moreover, we observed that sleep quality scores decreased as a function of the proximity to the epicentre, suggesting that the psychological effects of an earthquake may be pervasive and long-lasting. It has been widely shown that disruption of sleep by acute stress may lead to deterioration in memory processing. In fact, in a recent study we observed alterations in spatial memory in PTSD subjects. Our findings indicated that PTSD is accompanied by an impressive deficit in forming a cognitive map of the environment, as well as in sleep-dependent memory consolidation. The fact that this deterioration was correlated to the subjective sleep disturbances in our PTSD group demonstrates the existence of an intimate relationship between sleep, memory consolidation, and stress.

    the war Hoyle returned to Cambridge, but kept in close contact with his collaborators. Fred Hoyle was a canny and media-savvy scientist, 40 years before such things were recognized. Martin Rees said after his death '[He] also had other dimensions to his career, his inventiveness and skill as a communicator'. It is hard to realize now the impact that Hoyle's broadcasts had in post-war Britain. His programmes for the BBC on The Nature of the Universe won greater audiences than such unlikely rivals as Bertrand Russell and Tommy Handley. Even today many people recall how they were affected by listening to these broadcasts. Hoyle used one of his broadcasts to ridicule the hot explosion theory. He referred to the idea of a 'big bang as fanciful'. Unfortunately the name stuck, much to Hoyle's chagrin. In the 1950s Hoyle began a fruitful collaboration with Willy Fowler of the California Institute of Technology in Pasadena. Hoyle was interested in the origin of the chemical elements. Hans Bethe, Charles Critchfield and Karl-Frederich von Weizsäcker had calculated in 1939 how stars could turn protons into helium nuclei by nuclear fusion. Part of the Vela supernova remmant, the debris left after the type of massive explosion in which Hoyle predicted that heavy nuclei were formed. (© Royal Observatory, Edinburgh, Anglo-Australian Observatory.) Building on earlier collaboration with Ed Saltpeter, Hoyle used data supplied by Geoffrey and Margaret Burbidge and, working with Fowler, began to piece together how the elements were formed. By looking at very large stars near the end of their lives and examining their chemical composition, they noticed that the abundances of elements almost exactly corresponded to those with a low nuclear capture cross section. Hoyle argued that all of the elements in our bodies had been formed in stars that had been and gone before our solar system had even formed. In their classic paper the elements are produced by three basic methods. The

Cervical cancer screening: From the data obtained by the 2006 survey, 93.5% of theoretical extension was registered in the Centre of Italy, 65% in the North and 65.5% or in the South of Italy. 38.5% of invited women underwent a Pap-test. A decreasing trend in participation can be observed from Northern (45.6% to Central (35.7%, and to Southern (28.7% Italy. Colorectal cancer screening: In 2006, theoretical extension of colorectal cancer screening in Italy was 44%, with significant differences in geographical distribution (66.1% in the North of Italy 48.5% in the Centre and about 10% in the South of our country. About 907,000 people had a faecal occult blood test in 2006 (adjusted compliance of 44.6%. Data from the survey “Multiscopo sulle famiglie” showed that organised screening activity can reduce social inequalities of access to cancer screening, increasing screening utilization particularly in less educated people.

    Conclusions: Organised cancer screening programmes have been extended in recent years, improving the equity in the access to early diagnosis for the people invited. However, social and geographical inequalities still remain.

    Full Text Available This study analyzes the socio-economic factors that influence people’s decision to become fishermen in the central region of Ghana. Using a well structured interview schedule, a random sample of 98 people from Elmina in the central region of Ghana was selected for the study. Results from the descriptive statistics analysis of respondents identified fishing as a family business, minimum skills requirement and ready market for fish demand as factors that motivated majority of the people into fishing. Lack of storage facilities, access to credit, lack of government assistance and unpredictable changes in weather conditions on sea were the main constraints to fishing activities. Results from the logistic regression model indicated that household size and access to credit were significant factors that positively influenced people’s decision to become fishermen. The regression analysis further revealed that engaging in other income generating activity and being educated significantly reduces the probability to start fishing business.

  9. Determining the origin of carbon dioxide and methane in the gaseous emissions of the San Vittorino plain (Central Italy) by means of stable isotopes and noble gas analysis

    International Nuclear Information System (INIS)

    Highlights: ► Chemistry and isotope ratios (He, C, H) of free gases from San Vittorino plain (central Italy). ► CO2 is mainly originated by thermo-metamorphic reaction of limestone. ► The degassing is concentrated in fault zones. ► CH4 is mainly produced by thermogenic processes. ► Microbial oxidative process affects the isotopic composition of CH4. - Abstract: The chemistry and isotope ratios of He, C (δ13C) and H (δD) of free gases collected in the San Vittorino plain, an intramontane depression of tectonic origin, were determined to shed light on mantle degassing in central Italy. The C isotopic composition of CO2 (δ13C–CO2 −2.0‰ to −3.8‰) and He isotope ratios (R/RA 0.12–0.27) were used to calculate the fraction of CO2 originating from mantle degassing vs. sedimentary sources. The results show that CO2 predominantly (average of 75%) derives from the thermo-metamorphic reaction of limestone. Between 6% and 22% of the CO2 in the samples derives from organic-rich sedimentary sources. The mantle source accounts for 0–6% of the total CO2; however, in two samples, located in proximity to the most important faults of the plain, the mantle accounts for 24% and 42%. The presence of faults and fractures allows upward gas migration from a deep source to the Earth’s surface, not only in the peri-Tyrrhenian sector, as generally reported by studies on natural gas emissions in central Italy, but also in the pre-Apennine and Apennine belts. Isotope ratios of CH4 (δ13C–CH4 −6.1‰ to −22.7‰; δD–CH4 −9‰ to −129‰) show that CH4 does not appear to be related to mantle or magma degassing, but it is the product of thermal degradation of organic matter (i.e. thermogenic origin) and/or the reduction of CO2 (i.e. geothermal origin). Most of the samples appear to be affected by secondary microbial oxidation processes

    The objective of this study is the comparison between crop evapotranspiration measurements by eddy covariance (ETEC) and estimates by FAO-56 method (ETC). An open patch eddy covariance (EC) system has been installed in the middle of an alfalfa farmland in Central Italy. The EC system consisted of a 3D sonic anemometer/thermometer (model CSAT3) and a gas-analyzer (model Li-7500). CSAT3 and Li-7500 measured three-directions fluctuations of wind, sonic temperature, and concentrations of H2O and CO2 at 20Hz. These instruments allowed to measure independently latent heat flux (LE) and sensible heat flux (H). Soil heat flux (G) and net radiation (Rn) were measured using soil heat flux plates (model HFP01) and a net radiometer respectively, in order to check energy balance closure. All the sensors were connected to a datalogger (model CR3000) and the 10-min statistics (average, variance and covariance) were computed. Daily precipitation and air temperature were also recorded. The sensors were placed at 1.8m height over the soil surface. Available energy (Rn-G) systematically exceeds the measured fluxes (LE+H), being the underestimation of LE+H between 10 and 30%. Therefore, in accordance to the literature, the energy balance closure was considered to provide evidence for the validity of the results on LE. The evapotranspiration was measured by the EC system between days of the year 2009 (DOY) 130 (10th May) and 153 (2nd June), corresponding to the first 24 days of the 2nd cutting cycle of the growing season and between DOY 190 (9th July) and 240 (21st August), the whole 3rd cutting cycle of the growing season. For the same periods crop evapotranspiration was also calculated as the product between reference evapotranspiration (ET0) estimated by the FAO Penman-Monteith equation and the factor Kc×Ks (where Kc, crop coefficient; Ks, water stress coefficient, FAO-56 method). Tabulated Kc values, adjusted for the specific air humidity and wind speed conditions measured at the

    Full Text Available Normal 0 14 false false false MicrosoftInternetExplorer4 Aim of the work is to provide further knowledge on the silvicultural system applied to Quercus cerris hight forests in the Molise Region (Central Italy. An historical analysis, based on a number of forest management plans applied since 1940 referred to 19 municipalities and on other historical documents, is provided in the paper. Forest management has been traditionally applied in the Molise Region and therefore is at now possible to reconstruct in detail the management of the forests of Molise Region. The historical study has been integrated with the analysis of a chronosequence including four steps of stand development in a Turkey oak stand: the regeneration phase (1-2 yrs - the unthinned young stand (46 yrs - the unthinned adult stand (aged 60 to 100 - the mature stand (126 yrs. Mensurational surveys were carried out at each phase in order to characterize both stand structure and derive information on the silvicultural practices applied in the past, but not documented in the available papers. The stand age was determined by tree coring and count of annual rings. At the beginning of the last century, the silvicultural system to be applied in oak high forests wasn’t strictly defined and a particular kind of selection cutting was carried out. It was named taglio a salto per sezioni i.e. “compartment selection cutting”, partly leading back to a real selection cutting, partly to a shelterwood system. The use of the reported silvicultural system gave rise to irregular forest structures and led to management problems well-described in the management plans at the end of 1940s. Another consequence of the applied practices was the absence or the inadequate natural regeneration establishment. The contemporary unregulated practice of grazing the forest floor contributed to the unsuccessful regeneration and made the situation worse.

    Full Text Available We computed one-dimensional ( I D velocity models and station corrections for Centrai and Southern Italy, in- verting re-picked P-wave alTival times recorded by the Istituto Nazionale di Geofisica seismic network. The re-picked data yield resolved P-wave velocity results and proved to be more suited than bulletin data for de- tailed tomographic studies. Using the improved velocity models, we relocated the most significant earthquakes which occurt.ed in the Apennines in the past 7 years, achieving constrained hypocentral determinations for events within most of the Apenninic belt. The interpretation of the obtained lD velocity models allows us to infer interesting features on the deep structure of the Apennines. Smooth velocity gradients with depth and low P-wave velocities are ob,'ierved beneath the Apennines. We believe that our results are effective to constrain hypocentral locations in Italy and may represent a first step towards more detailed seismotectonic analyses.

  13. Comparison between the diurnal trends of ozone and radon gas concentrations measured at ground in the semi-rural site of Central Italy

    International Nuclear Information System (INIS)

    In this paper the results of a four-year monitoring campaign carried out in a semi-rural site near Urbino, Central Italy, for ozone and for radon gas are reported and discussed. Radon can be considered as an index of vertical diffusion in the boundary layer. Its trend evidences the presence of temperature inversion such as the formation of the nocturnal stable layer and gives information on the vertical turbulence and the motion of air masses. Therefore, a simple measurement of radon concentration at ground resulted to describe the temporal evolution of the pollutants in the atmosphere. A comparison between the daily concentrations trend of ozone with that of radon gas was performed. The evolution of the convective boundary layer during daytime and the stable nocturnal boundary layer (NBL) were found to have marked impacts on ozone concentrations. (author)

    An ethnopharmaceutical study focused on domestic cosmetics, cosmeceuticals, and remedies to heal skin diseases traditionally used in the inland part of the Marches region (Central-Eastern Italy) has been conducted. At present, traditional knowledge concerning home-made phytocosmetics is represented by both the remnants of an orally transmitted folk heritage and also by new forms of knowledge, sometimes coming from popular phytotherapeutical books and the mass media (out of the scope of this survey), but also as a result of recent migration trends from Eastern Europe. We recorded approximately 135 cosmetic or cosmeceutical preparations prepared from more than 70 botanical species and a very few animal or mineral ingredients. Among the recorded preparations, developing a clear distinction amongst cosmetics, cosmeceuticals and pharmaceuticals for skin diseases is very problematic, confirming that in folk knowledge systems medicinal products for healing skin diseases and cosmetics have often been perceived as two poles of a continuum. Many of the quoted species represented well-known medicinal plants of the European phytotherapy, although we also recorded a few unusual plant taxa, which are briefly discussed under the perspective of their eventual phytochemical and/or phytopharmacological potentialities. Exotic drugs or precious essences, even native of the Mediterranean, were not quoted as ingredients for preparing perfumes and fragrances by the interviewees of the present study, thus indicating that popular cosmetic practices in rural Central Italy have taken a much separated path away from the cosmetic "know-how" of the aristocracy and high bourgeois classes of the last centuries.

    Full Text Available This paper presents the most relevant aspects of the academic debate on smart power, in order to apply this concept to analyze the foreign policy of the Republic of China on Latin America and the Caribbean, but especially to Central America; where the dispute between China and Taiwan for international recognition is evident. It is argued that the smart power of China to Central America is expressed in the attractiveness of having privileged access to the Chinese market and its funding programs and official development assistance. While this country has a large presence in Latin America and the Caribbean, in Central America such influence is counteracted in the light of the close relationship that all Central American countries except Costa Rica, maintain with Taiwan. Based on the development of China as a world power, it is expected that this condition changed, so that this country would increase its influence in Central America.

    European Community Water Framework Directive (WFD) and its derivative regulations have recognized the urgent need to adopt specific measures against the contamination of water bodies by individual pollutants that may significantly affect the quality of water itself. Italian regulation takes into account the EU Directives, and charges the regional authorities to create monitoring networks and produce assessment reports on the contamination of groundwater. The knowledge of "natural baseline" for various dissolved elements in groundwaters on a regional scale becomes of primary importance to distinguish natural sources and anthropogenic inputs. The studied area includes the whole Tuscan regional district (central Italy) and covers an area of about 23,000 km2. From a geolithological point of view, Tuscan territory consists of several complexes outcropping regionally, the most typical features being the Mesozoic and Cenozoic carbonate and evaporitic formations, overlain by flysch sequences, as well as granite intrusions and volcanic rocks. Moreover, two geothermal areas (Larderello and Mt. Amiata), a large number of thermal springs and CO2-rich gas vents are mostly present in the central-southern part of Tuscany. Finally in southern Tuscany (e.g. Campiglia M.Ma, Mt. Amiata, Elba Island), mining districts, predominantly characterized by polimetallic sulphides ore deposits, were exploited since the Etruscan time. In this work statistical distribution models are used to develop summary statistics and estimate probabilities of exceeding water-quality standards according to the National Legislative Decree 152/06. Descriptive statistics on solute concentrations are based on geochemical data from the main Tuscan aquifers and investigated by the CNR-IGG (Institute of Geosciences and Earth Resources of Pisa, Italy) and Department of Earth Sciences (University of Florence, Italy). The data processing was carried out on 4,767 water samples collected from 1997 to 2009. According to

    Full Text Available The dynamic model MAGIC was calibrated and applied to selected sites in north-western Italy (3 rivers, 10 alpine lakes to predict the future response of surface water to different scenarios of atmospheric deposition of S and N compounds. Results at the study sites suggest that several factors other than atmospheric deposition may influence the long-term changes in surface water chemistry. At present the lumped approach of dynamic models such as MAGIC cannot represent all the processes occurring at the catchment scale. Climate warming in particular and its effects on surface water chemistry proved to be important in the study area. Furthermore the river catchments considered here showed clear signs of N saturation. This condition and the increasing concentrations of NO3 in river water were simulated using N dynamics recently included in MAGIC. The modelling performed in this study represents the first application of MAGIC to Italian sites. The results show that inclusion of other factors specific to the Mediterranean area, such as dust deposition and climate change, may improve the fit to observed data and the reliability of the model forecast. Despite these limitations, the model captured well the main trends in chemical data in both rivers and lakes. The outputs clearly demonstrate the benefits of achieving the emission reductions in both S and N compounds as agreed under the Gothenburg Protocol rather than making no further emission reductions. It was also clear that, besides the substantial reduction of SO4 deposition from the peak levels of the 1980s, N deposition must also be reduced in the near future to protect freshwaters from further acidification.

    Invasive species are a significant threat to affected ecosystems, having serious environmental, economic and social impacts. The maritime pine bast scale, Matsucoccus feytaudi Ducasse (Hemiptera: Matsucoccidae), causes serious damage to Pinus pinaster forests in SE France, Corsica and Italy where it has been introduced. This study illustrates the adaptive management plan implemented in the Migliarino, San Rossore, Massaciuccoli Regional Natural Park in Tuscany, Italy, where M. feytaudi arrived in 2004, leading to the decay of local P. pinaster stands. The management programme, aimed at slowing the establishment and growth of M. feytaudi, was carried out in the main sector of the park, Tenuta di San Rossore, to retard the destruction of the P. pinaster coastal strip protecting the more internal woodland from sea salt and to allow replacement of P. pinaster trees with a more stable broad-leaved wood. The combined use of mass trapping and silvicultural interventions, applied in a targeted manner according to distribution maps of pest captures and damage, helped to delay forest destruction compared with a nearby unmanaged area of the park Tenuta di Tombolo. Although M. feytaudi continued to spread during the management period, the populations remained at low levels for 6 years, showing a marked increase in 2012. During this period, the P. pinaster stands were reduced from 320 to 249 ha. The final result of this ongoing gradual conversion process will be transformation of the P. pinaster forest into Holm oak woods and Mediterranean shrub land, while P. pinaster will survive as clusters or blocks of trees.

  20. Practice patterns for prostate cancer in nine central and northern Italy radiation oncology centers: a survey including 1759 patients treated during two decades (1980-1998)

    International Nuclear Information System (INIS)

    Purpose: Prostate cancer patients in Italy are offered the choice of the full spectrum of possible treatment options for their disease, but the diffusion of the more recent technological refinements among the Radiation Oncology centers is not homogeneous and there is a need to establish a reference 'historical' data source. This retrospective study describes the changing patterns in prostate cancer patient practice and the therapeutic results obtained in nine Radiation Oncology centers of Northern and Central Italy (five in Northern Italy and four in Central Italy). Methods and Materials: A total of 1759 prostate cancer patients, radically treated in the nine radiotherapy (RT) centers between 1980 and 1998, made up the study population. Data collected for each patient included clinical, pathologic, therapeutic features, and toxicity. The overall survival, disease-specific survival (DSS), and clinical relapse-free survival (RFS) were calculated for the whole series and for the subsets of patients defined by different clinical, pathologic, and therapeutic features, according to three accrual periods (A, 1980-1990; B, 1991-1994; and C, 1995-1998). Univariate and multivariate analyses were performed to identify prognostic factors related to survival and late adverse effects (cystitis and proctitis) probability. Results: Patient accrual increased markedly during the 2 decades considered, and the percentage of cases with Stage C or D disease dropped from 49% (period A) to 43% (period B) to 37% (period C) (p6 Gy in 44%, 84%, and 93% of the patients treated in period A, B, and C, respectively); a reduction in treated volumes, including pelvic lymphatic drainage (56-39% before 1995, 22% thereafter); and an increase in cases treated in association with hormonal therapy (50% before 1991, 80% thereafter). Lower energy (<10 MV) photon beams were progressively abandoned (12% before 1990 vs. 6-7% thereafter), along with an increase in the use of blocks (60% in the last 4 years of

    Full Text Available The Monte Corchia cave system, one of the most famous and popular caves in Italy, has in recent times been the subject of investigation on its speleothems as paleoclimate archives. This paper describes the geology, geomorphology and water chemistry of the cave system with the aim to elucidate the processes that have generated these speleothems and the properties they contain that are so useful for paleoclimatology. Some general conclusions can be drawn: i the Corchia system is a cave developed over different altitudes during progressive uplift of the mountain chain in which it is located, probably under drainage conditions very different to those of the present. This has allowed the development of a large (ca. 60 km and deep (-1187 m karst system; ii the dewatering phases have left the deepest chambers far away from clastic input and with long drip pathways; iii the peculiar geological context has permitted the water to intercept and dissolve a significant source of U (still unknown that facilitates radiometric dating; iv in the last 1 Ma at least, no significant changes have occurred in the relief and in the epikarst, in the sense that speleothems have grown under very similar conditions. In addition the extremely low Ca concentration of drip waters have permitted low speleothem growth rates and, at least for the “Galleria delle Stalattiti”, the zone under paleoclimate studies,a stable plumbing system (i.e. chemistry and stable isotopes of drip waters has produced calcite close to isotopic equilibrium.

    CT scanning analysis applied to vertebrate palaeontology is providing an increasing number of data of great interest. This method can be used in many branches of palaeontology such as the investigation of all the fossilized elements in a hard matrix and the hidden structures in the bones. A large number of pathologies are "hidden", completely or partially invisible on the external surface of the bones because their development took place within the bones. However, the study of these diseases and abnormalities plays a crucial role in our understanding of evolutionary and adaptive processes of extinct taxa. The analysis of a partial skeleton of the sabre-toothed felid Megantereon whitei from the Early Pleistocene karst filling deposits of Monte Argentario (Tuscany, Italy) has been carried out. The CT scanning analysis put in evidence the presence of supernumerary teeth (P2) and the absence of P3 in the mandible. The occurrence of P2 can be considered as an evidence of atavism. Such an archaic feature is recorded for the first time in Megantereon.

    This study investigates seasonality of marriages and reproductive isolation in six long-isolated communities in the central Apennines (Italy). It had two objectives: (1) the identification of an Apennine biodemographic model in comparison with mountain communities of other regions, and with non-Apennine communities in Abruzzo, and (2) to identify the possible effects of the drainage of Lake Fucino (1854-1876) on that area. Marriages in this region show two very stable seasonal patterns: one is typical of sedentary rural societies, with summer migrations and marriages preferentially celebrated in the winter, and the other has marriages that are strongly concentrated in the summer months, i.e. between 75% and 93.5% of marriages were celebrated between June and October in these communities in the 1800s. These were traditionally pastoral communities with winter transhumance of the flocks and their shepherds towards the lowlands of southern Italy. In both groups, restrictions imposed by the Catholic Church do not seem to have affected the timing of marriages. Indeed, economic factors related to work activities seem to have had more influence. Concerning reproductive isolation, the results show high rates of endogamy: between 85% and 98% in both the 19th and 20th centuries. Rates of consanguineous marriages were between 5% and 20%, and those of isonymous marriages rarely exceeded 9%. The coefficient of inbreeding a shows that there was a delayed, limited period of increased consanguinity in the few decades around the turn of the century. This is different from the national situation, and thus could be a consequence of the Lake Fucino drainage. PMID:11446403

    Full Text Available The present paper is the second in a series devoted to the revision of the Pliocene naticids of Northern and Central Italy. It concludes the section covering the calcareous operculum-bearing Naticinae and expands to 18 the total number of species and subspecies of this subfamily recovered so far from the Pliocene deposits of Italy. Of the six taxa considered in this study, two (epigloafuniculata and fredianii fully match the characters of the genus Cochlis Röding, 1798, one (koeneni is assigned to the genus Tanea Marwick, 1931, the rest (astensis, prietoi and tectula belong to the genus Tectonatica Sacco, 1890. All the six taxa considered in this paper are described and commented in the systematic account. One, Cochlis fredianii, is proposed as new. In the chapter treating the generic assignment of the studied taxa, the range of Tanea, hitherto used to allocate several Indo-Pacific species, is extended to the Mediterranean Basin as well, and the relations between Tectonatica and Cryptonatica Dall, 1892 are discussed. This study further demonstrates that the morphological characters of the teleoconch are of low significance in species recognition. In fact, should the characters be ranked, the operculum comes first and is the primary element, sufficient to distinguish each species. The protoconch and the color pattern are the second and third relevant attributes that can be used diagnostically for several taxa, but not always. The other shell features appear to be useful tools in separating species only occasionally. Some species lack distinctive shell characters and do require operculate specimens in order to be confidently

    Abstract: This paper looks at the circulation of goods, capital and people between the 'buffer zone' consisting of Poland, Czech Republic, Slovakia and Hungary and Western Europe (Germany and Austria) on the one side, Eastern Europe (Ukraine, Russia, Belarus) on the other side. It is argued in the paper that in order to understand these economic relations between the different countries, we have to consider the historical and cultural links which existed already between them.

    People with autism, their families, and their specialised caregivers are a social group at high health risk after a disruptive earthquake. They need emergency assistance and immediate structured support according to definite protocols and quality standards. We recommend to establish national guidelines for taking-in-charge people with autism after an earthquake. The adaptive behaviour of participants with autism declined dramatically in the first months after the earthquake in all the dimensions examined (i.e., communication, daily living, socialisation, and motor skills). After relatively stable conditions returned and with immediate and intensive post-disaster intervention, children and adolescents with autism showed a trend towards partial recovery of adaptive functioning. As to the impact on services, this study indicates the need for supporting exposed caregivers at high risk of burnout over the first two years after the disaster and for an immediate reorganisation of person-tailored services.

    Full Text Available Understanding how stigmatized identities contribute to increased rates of depression and anxiety is critical to stigma reduction and mental health treatment. There has been little research testing multiple aspects of stigmatized identities simultaneously. In the current study, we collected data from a diverse, urban, adult community sample of people with a concealed stigmatized identity (CSI. We targeted 5 specific CSIs--mental illness, substance abuse, experience of domestic violence, experience of sexual assault, and experience of childhood abuse--that have been shown to put people at risk for increased psychological distress. We collected measures of the anticipation of being devalued by others if the identity became known (anticipated stigma, the level of defining oneself by the stigmatized identity (centrality, the frequency of thinking about the identity (salience, the extent of agreement with negative stereotypes about the identity (internalized stigma, and extent to which other people currently know about the identity (outness. Results showed that greater anticipated stigma, greater identity salience, and lower levels of outness each uniquely and significantly predicted variance in increased psychological distress (a composite of depression and anxiety. In examining communalities and differences across the five identities, we found that mean levels of the stigma variables differed across the identities, with people with substance abuse and mental illness reporting greater anticipated and internalized stigma. However, the prediction pattern of the variables for psychological distress was similar across the substance abuse, mental illness, domestic violence, and childhood abuse identities (but not sexual assault. Understanding which components of stigmatized identities predict distress can lead to more effective treatment for people experiencing psychological distress.

    Trisetacus juniperinus (Nalepa) sensu Keifer (Acari: Eriophyoidea: Phytoptidae) causes irregular development of buds, shoot deformations and stunted growth of trees, resulting in a serious threat to nurseries and young stands of Cupressus sempervirens L. (Mediterranean cypress). Recently, some cypress clones selected for their resistance to the fungal canker agent Seiridium cardinale (Wag.) have shown high susceptibility to the mite. Considering its tiny body, its hidden lifestyle inside the buds and the probable occurrence of other species (the vagrant Epitrimerus cupressi (Keifer) is common on the Mediterranean cypress in Italy), detection and monitoring of T. juniperinus require taxonomic expertise and are often time-consuming and challenging before serious damage is discernible. In the present study, a rapid, cost-effective PCR-based method was developed and validated to detect T. juniperinus on cypresses. The cytochrome c oxidase subunit I gene was amplified with degenerate and specific primers, but the latter were the only ones able to discriminate between T. juniperinus and E. cupressi. PCR products distinguished the two species both in a pool of individuals in a mixed population of both species and in single individuals, indicating the sensitivity of the detection method. PCR-RFLP (restriction fragment length polymorphism) by means of XmnI and XbaI endonucleases separated the two species. Furthermore, a washing-sieving protocol was used to make mite collection from the tree sample faster and simpler; this procedure did not interfere with the molecular detection of the species. The possibility of the routine use of this assay to monitor quarantine eriophyoids infesting plant material is discussed. PMID:24030201

    The Quaternary Roman Volcanic Province extends for over 200 km along the Tyrrhenian margin of the Italian peninsula and is composed of several caldera complexes with significant associated geothermal potential. In spite of the massive programs of explorations conducted by the then state-owned ENEL and AGIP companies between the 1970s and 1990s, and the identification of several high enthalpy fields, this resource remains so far unexploited, although it occurs right below the densely populated metropolitan area of Roma capital city. The main reason for this failure is that deep geothermal reservoirs are associated with fractured rocks, the secondary permeability of which has been difficult to predict making the identification of the most productive volumes of the reservoirs and the localisation of productive wells uncertain. As a consequence, almost half of the many exploration deep bore-holes drilled in the area reached a dry target. This work reviews available data and re-assesses the geothermal potential of caldera-related systems in Central Italy, by analysing in detail the case of the Colli Albani caldera system, the closest to Roma capital city. A GIS based approach identifies the most promising reservoir volumes for geothermal exploitation and uses an improved volume method approach for the evaluation of geothermal potential. The approach is based on a three dimensional matrix of georeferenced spatial data; the A axis accounts for the modelling of the depth of the top of the reservoirs based on geophysical and direct data; the B axis accounts for the thermal modelling of the crust (i.e. T with depth) based on measured thermal gradients. Both A and B data are necessary but not sufficient to identify rock volumes actually permeated by geothermal fluids in fractured reservoirs. We discuss the implementation of a C axis that evaluates all surface data indicating permeability in the reservoir and actual geothermal fluid circulation. We consider datasets on: i

    Magma-carbonate rock interaction is investigated through a geochemical and Sr-Nd-O isotope study of granular lithic clasts ( ejecta) from the Alban Hills ultrapotassic volcano, Central Italy. Some samples (Group-1) basically represent intrusive equivalents of Alban Hills magmas. A few samples (Group-2) are ultramafic, have high MgO (˜30 to 40 wt%) and δ 18O‰, and originated by accumulation of mafic phases that crystallised from ultrapotassic melts during assimilation of dolomitic rocks. Group-3 ejecta consist of dominant K-feldspar, and show major element compositions similar to phonolites, which, however, are absent among the Alban Hills volcanics. Finally, another group (Group-4) contains corroded K-feldspars, surrounded by a microgranular to porphyritic matrix, made of igneous minerals (K-feldspar, foids, clinopyroxene, phlogopite) plus wollastonite, garnet, and some cuspidine. Group-4 ejecta are depleted in SiO 2 and enriched in CaO with respect to Group-3. The analysed ejecta have similar 143Nd/ 144Nd (0.51204-0.51217) as the Alban Hills lavas, whereas 87Sr/ 86Sr (0.70900-0.71067) is similar to lower. Whole rocks δ 18O‰ ranges from +7.0 to +13.2, reaching maximum values in ultramafic samples. A positive correlation with CaO is observed in single rock groups. Large Ion Lithophile Element (LILE) abundances and REE fractionation are generally high, and extreme values of Th, U and LREE are found in some Group-3 and Group-4 rocks. Mineralogical, petrological and geochemical data reveal extensive interaction between magma and carbonate wall rocks, involving both dolostones and limestones. These processes had dramatic effects on magma compositions, especially on phonolites, which were transformed to foidites. Evidence of such a process is found in Group-4 samples, in which K-feldspar is observed to react with a matrix that represents strongly undersaturated melts formed by interaction between silicate magma and carbonates. Trace element data also testify to a

    A multi-proxy record (lithology, XRF, CaCO3 content, carbonate δ18O and δ13C) was acquired from a sediment core drilled in the intermountain Sulmona basin (central Italy). Tephrostratigraphic analyses of three volcanic ash layers ascribe the investigated succession to the MIS 12-MIS 11 period, spanning the interval ca. 500-410 ka. Litho-pedo facies assemblage indicates predominant lacustrine deposition, interrupted by a minor sub-aerial and lake low stand episode. Variations in major and minor elements concentrations are related to changes in the clastic input to the lake. The oxygen isotopic composition of carbonate (δ18Oc) intervals is interpreted mainly as a proxy for the amount of precipitation in the high-altitude catchment of the karst recharge system. The record shows pronounced hydrological variability at orbital and millennial time-scales, which appears closely related to the Northern Hemisphere summer insolation pattern and replicates North Atlantic and west Mediterranean Sea Surface Temperature (SST) fluctuations. The MIS 12 glacial inception is marked by an abrupt reduction of precipitation, lowering of the lake level and enhanced catchment erosion. A well-defined and isotopically prominent interstadial with increased precipitation maybe related to insolation maxima-precession minima at ca. 465 ka. This interstadial ends abruptly at ca. 457 ka and it is followed by a phase of strong short-term instability. Drastic lake-level lowering and enhanced clastic flux characterized the MIS 12 glacial maximum. Lacustrine deposition restarted about 440 ka ago. The MIS 12-MIS 11 transition is characterized by a rapid increase in the precipitation, lake-level rise and reduction in the clastic input, interrupted by a short and abrupt return to drier conditions. Comparison with marine records from the Iberian margin and western Mediterranean suggests that major events of ice rafted debris deposition, related to southward migrations of the polar front, match the

    An 82 m long sedimentary succession was retrieved from the Fucino Basin, the largest intermountain tectonic depression of the central Apennines. The basin hosts a succession of fine-grained lacustrine sediments (ca. 900 m-thick) possibly continuously spanning the last 2 Ma. A preliminary tephrostratigraphy study allows us to ascribe the drilled 82 m long record to the last 180 ka. Multi-proxy geochemical analyses (XRF scanning, total organic/inorganic carbon, nitrogen and sulfur, oxygen isotopes) reveal noticeable variations, which are interpreted as paleohydrological and paleoenvironmental expressions related to classical glacial-interglacial cycles from the marine isotope stage (MIS) 6 to present day. In light of the preliminary results, the Fucino sedimentary succession is likely to provide a long, continuous, sensitive, and independently dated paleoclimatic archive of the central Mediterranean area.

  13. Modeling the effects of pumping wells in spring management: The case of Scirca spring (central Apennines, Italy)

    One of the techniques used to increase the water yield of springs during dry seasons and droughts is drilling wells close to them. Where there is a low-hydraulic conductivity boundary close to a spring (the case considered here), this technique implies low well efficiency, high drawdown, and high cost of withdrawals. In addition, a set of pumping wells close to a spring can cause both it and the stream originating from it to dry up - a situation which is not always acceptable from an environmental point of view. In order to study better management strategies, this paper presents a finite difference model of the Scirca spring (Umbria - Marche Apennines, Italy), which originates from a limestone massif in which some formations are karstified. The model, built with Modflow using the equivalent porous media (EPM) approach, simulated the effects of pumping wells at various distances from the spring. Hydraulic Conductivity and Storativity were calibrated and validated on discharge data during recession, when recharge is nil. "Inverse modeling" was then used to estimate the daily recharge of the hydro-geological system of the Scirca spring for a period of several years. Lastly, the efficiency of various management schemes was evaluated by simulating the reaction of the spring, in terms of discharge, to a series of pumping scenarios, all guaranteeing a certain imposed withdrawal during summer, much larger than the natural spring discharge, given by spring discharge and well drawdown. The wells were located between 2850 and 100 m from the spring, the pumping time-span was set at 90 days, and pumping rates of 60, 90 and 120 l/s were applied. Results show that the maximum discharge at which spring drainage is avoided and that minimum vital flow is guaranteed is 90 l/s. The higher water volumes extracted during summer (dry season) are balanced by a lowering of the maximum natural discharges in winter and spring (recharge seasons). Simulations indicate that, by drilling pumping

    A recent study of the Matuyama-Brunhes (M-B) geomagnetic field reversal recorded in exposed lacustrine sediments from the Sulmona Basin (Italy) provided a continuous, high-resolution record indicating that the reversal of the field direction at the terminus of the M-B boundary (MBB) occurred in less than a century, about 786 ka ago. In the sediment, thin (4-6 cm) remagnetized horizons were recognized above two distinct tephra layers-SUL2-19 and SUL2-20-that occur ˜25 and ˜35 cm below the MBB, respectively. Also, a faint, millimetre-thick tephra (SUL2-18) occurs 2-3 cm above the MBB. With the aim of improving the temporal resolution of the previous Sulmona MBB record and understanding the possible influence of cryptotephra on the M-B record in the Sulmona Basin, we performed more detailed sampling and analyses of overlapping standard and smaller samples from a 50 cm-long block that spans the MBB. The new data indicate that (i) the MBB is even sharper than previously reported and occurs ˜2.5 cm below tephra SUL2-18, in agreement with the previous study; (ii) the MBB coincides with the rise of an intensity peak of the natural remanent magnetization (NRM) intensity, which extends across SUL2-18; (iii) except for a 2-cm-thick interval just above tephra SUL2-18, the rock magnetic parameters (k, ARM, Mr, Ms, Bc, Bcr) indicate exactly the same magnetic mineralogy throughout the sampled sequence. We conclude that either SUL2-18 resulted in the remagnetization of an interval of about 6 cm (i.e. during the NRM intensity peak spanning ˜260 ± 110 yr, according to the estimated local sedimentation rate), and thus the detailed MBB record is lost because it is overprinted, or the MBB is well recorded, occurred abruptly about 2.5 cm below SUL2-18 and lasted less than 13 ± 6 yr. Both hypotheses challenge our understanding of the geomagnetic field behaviour during a polarity transition and/or of the NRM acquisition process in the Sulmona lacustrine sediment.

    Full Text Available Gentile di maiale is a typical meat product prepared in some traditional plants of Latina Province (Central Italy. It is obtained from dehydration, salting, smoking and ripening of swine rectum. Aim of this study was to evaluate the influence of the traditional smoking process on polycyclic aromatic hydrocarbons (PAHs content by means of high-performance liquid chromatographic/fluorescence detection. Polycyclic aromatic hydrocarbons detected in 8 samples of raw material (swine rectum and samples of smoked gentile were: benzo[a]anthracene, chrisene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a] pyrene, benzo[a,h]anthracene. Their residues were detected in all samples of finished product. European Regulation 835/2011 established two levels of PAHs content in meat products. According to first levels, in force until September 2014, only 2 out of 8 samples exceeded legal limit. According to the subsequent, more restrictive, limits all samples would be non-compliant. An improvement and a standardisation of traditional smoking procedures are recommended.

    Water pollution from point sources has been considerably reduced over the last few decades. Nevertheless, some water quality problems remain, which can be attributed to non-point pollution sources, and in particular to agriculture. In this paper the results of a study intended to assess the consequences, in terms of NO3 water pollution, of growing a crop, whose impact in terms of P pollution is already well known, are presented. The potential consequences, in terms of water pollution from nitrates of a BMP expressly applied to reduce P pollution are also discussed. The study site is the Lake Vico basin, Central Italy, which has suffered a shift in trophic state since the mid 1990s, caused by P compounds used for intensive cultivation of hazelnut trees. The results of the monitoring campaign described in this paper allow to assert that hazelnut tree cropping has probably caused a considerable increase in nitrate concentration in the groundwater, although not in the lake water, because of the specific hydrogeological characteristics of the basin. The main conclusion is that monitoring is essential to single out environmental characteristics peculiar of a specific area, which even the most sophisticated model would not have been able to highlight. This is why monitoring and model simulations should be integrated. PMID:19911291

    Full Text Available Germination response under different photo- and thermo-periods was investigated in nine species of the association Parapholido-Artemisietum cretaceae, a typical plant community of clay badland vegetation in central western Italy. The species showed: (i more rapid germination under the photo- and thermo-period emulating autumn conditions than under the one emulating early spring conditions; (ii different germination rates under condition emulating periods with high diurnal insolation followed by high or low nocturnal heat dispersion: Aegilops geniculata, Parapholis strigosa and Artemisia cretacea were indifferent, Hordeum maritimum, Trifolium scabrum, Brachypodium distachyum and Parapholis incurva responded positively to higher thermal dispersion, whereas Medicago minima and Scorpiurus muricatus responded negatively; (iii different responses to a constant low temperature of 2oC: Artemisia cretacea, Parapholis incurva, Parapholis strigosa and Scorpiurus muricatus showed complete or very high dormancy; the other species showed a germination capacity between 55 and 87% in the following decreasing order: Medicago minima > Hordeum maritimum > Trifolium scabrum > Aegilops geniculata > Brachypodium distachyum. All species had delayed and reduced germination responses at 2oC. Grasses showed prompt, quick and high germination as environmental conditions became more favourable; legumes showed a similar response when their coat-imposed dormancy was removed, while the asteracea A. cretacea showed only a moderate germination capacity and one of the lowest germination rates.

    Spinel peridotite xenoliths found in the Monte Vulture carbonatite-melilitite volcano have been derived from the subcontinental lithospheric mantle beneath central southern Italy. Clinopyroxene-poor lherzolites and harzburgites are the most common rock types, with subordinate wehrlites and dunites. Small quantities of phlogopite and carbonate are present in a few samples. The peridotites record a large degree of partial melting and have experienced subsequent enrichment which has increased their LILE and LREE contents, but in most cases their HFSE contents are low. Despite being carried to the surface by a carbonatite-melilitite host, the whole-rock and clinopyroxene compositions of the xenoliths have a trace-element signature more closely resembling that of silicate-melt metasomatised mantle rather than carbonatite-metasomatised peridotites. 87Sr/86Sr and 143Nd/144Nd isotopic ratios for clinopyroxene from the Vulture peridotites are 0.7042-0.7058 and 0.51260-0.5131 respectively. They form a trend away from the depleted mantle to the composition of the host magmas, and show a significant enrichment in 87Sr/86Sr compared with most European mantle samples. The mantle beneath Monte Vulture has had a complex evolution - we propose that the lithosphere had already undergone extensive partial melting before being affected by metasomatism from a silicate melt which may have been subduction-related.

    Stachys alopecuros subsp. divulsa (Lamiaceae), a perennial herb endemic to central Italy growing on mountain pastures, was investigated for the first time for the content of secondary metabolites, for the micromorphology and histochemistry of glandular trichomes, and for the biological activity of the volatile oil, namely cytotoxic, antioxidant and antimicrobial. The plant showed the molecular pattern of iridoids, among which a new iridoid diglycoside (4'-O-β-D-galactopyranosyl-teuhircoside) was detected, together with a sterol glucoside and a phenylethanoid glycoside. The essential oil from the flowering aerial parts was characterized by a high proportion of sesquiterpene hydrocarbons (65.1%), with (E)-caryophyllene (33.2%) as the most abundant, while other main components were germacrene D (7.6%), α-humulene (6.4%) and the oxygenated cis-sesquisabinene hydrate (10.2%). Taken together, polar and apolar chemical profiles support the classification of the species within the section Betonica of the genus Stachys. Micromorphological study revealed three types of glandular hairs secreting different classes of compounds, with type A peltate hairs producing the bulk of the essential oil. MTT assay revealed the potential of the volatile oil in inhibiting A375, HCT116 and MDA-MB 231 tumor cells (IC₅₀ values below 20 μg/ml). PMID:23827382

    Full Text Available Square wave anodic stripping voltammetry (SWASV was used to determine Cd, Pb and Cu in spring waters of the Sibylline Mountains National Park, Central Italy. Samples were collected from three different areas of the Park (Mount Bove North, Mount Bove South and Springs of River Nera during the period 2004-2011. Physical-chemical parameters were also determined to obtain a general characterization of the waters. Very low metal concentrations were observed (i.e., Cd 1.3±0.4 ng L-1, Pb 13.8±5.6 ng L-1, Cu 157±95 ng L-1, well below the legal limits and also below the medians of known Italian and European data. Comparing the three areas it was noted that waters from the area of the Nera Springs are the poorest in heavy metals and the richest in minerals, that conversely the waters of Mt. Bove North are the richest in heavy metals and the poorest in mineral salts, and finally that intermediate values both for heavy metals and mineral salts were observed for the waters of Mt. Bove South.

    Human papillomavirus (HPV) infection and type-specific prevalence at anal, oral, coronal sulcus, and urethral mucosa in fifty HIV positive men having sex with men (MSM) were evaluated; patients were enrolled in a non-metropolitan area of Central Italy. Clinical and socio-demographic information, drug, and sexual behaviors were obtained for each participant. HPV was detected by PCR from an overall of 200 specimens, and genotyping was performed by both Restriction Fragment Length Polymorphism analysis and sequencing. HPV DNA was found in 60.0% (n = 30) of HIV positive MSM, and prevalence was higher at anal canal (n = 28, 56.0%) compared to all the other anatomical sites (χ(2) test P HPV-58 was more frequently detected (n = 9, 47.4%) respect to HPV-16 (n = 6, 31.6%). This is the first report on HPV detected at four anatomical sites involved in sexual practices in HIV positive MSM. We found an unusual distribution of oncogenic genotypes with an exceeding prevalence of HPV-58 respect to HPV-16. Hence, the recently licensed nonavalent vaccine should be suitable to prevent a larger number of infections caused by potentially emerging high-risk genotypes. J. Med.

    At present the genetic and demographic characterization of the trout populations is completed. Table 1 and Figures 1-2 show the results of abundance analysis of the fish assemblages divided by basin. The standing crop’s mean values can be considered in the standard range, according to the small size and the limited productivity that generally characterized the watercourses analyzed, as most of the Apennine rivers. The differences of the mean values among basins were highly statistically significant according to the ANOVA analysis (density: F= 5.24, p=0.001; standing crop: F=12.42, p=0.001. The results of genetic analysis separated clearly native and aliene genomes (K = 2, Fig. 3a and showed the presence of three distinct genetic stocks of native Apennine trout (K = 4, Fig. 3b: i Tevere (green bars, ii Tenna (red and iii Chienti /Potenza/Metauro/Esino (yellow. Populations characterized by very low introgression values will be the source of wild individuals to produce pure juvenile trouts in captivity. Four moderately introgressed populations will be subject to supportive breeding activities. Finally, six stream, where trouts showed almost exclusively an alien genetic make-up will be selected for the eradication activities. The data collected are the indispensable premise for the adoption of the necessary strategies for conservation of the Apennine trout in Central Italy.

    Full Text Available Incomplete reproductive barriers between species, especially in sympatric areas where several species coexist, may result in hybridization and an increase in genetic diversity. Here we assessed the amount of genetic diversity in a community of three interfertile and sympatric European oaks (Quercus frainetto Ten., Q. petraea Liebl. Matt. and Q. pubescens Willd. situated in central Italy. We used 11 microsatellite markers derived from Expressed Sequence Tag (EST-SSRs and we implemented a Bayesian clustering analysis to assign individuals to species or hybrids. All genotyped loci were polymorphic for all the species and three genetic clusters corresponding to each species were detected. Significant differences and a higher level of gene flow were observed between the three oak species. Occurrence of hybrids varied markedly within the studied area: hybrids between Q. petraea and Q, pubescens were the most frequent, while hybrids between Q. petraea and Q. frainetto were particularly rare. Q. pubescens and Q. petraea showed the highest number of alleles compared to Q. frainetto,which was characterized by a low number of private, but highly frequent, alleles. However, Q. frainetto showed a lower genetic diversity and a stronger reproductive isolation from the other two oak species.

    The results of a biomonitoring survey carried out in the town of Montecatini Terme (central Italy) in the period 1993-2000 using the biodiversity of epiphytic lichens and the accumulation of heavy metals in thalli of Flavoparmelia caperata as indicators of air pollution are reported. From 1993 to 2000, the mean ILD value for the whole study area increased from 18+/-18 to 42+/-22, the lowest ILD value increased from 0 to 11 and the highest ILD value increased from 67 to 84. A 'lichen desert' was found only in 1993 and stations classified as 'natural' were lacking only in 1993 and 1996. Concentrations of all heavy metals decreased from 1993 to 1999. It is concluded that vehicular traffic is the main source of atmospheric pollution in the study area. The most likely changes that may have caused lichen communities to improve and heavy metals to drop is conversion of heating systems to methane (abatement of SO2) and the use of unleaded gasoline (reduction of Pb). The present results showed that despite their slow growth rate, lichens respond rapidly to decreasing concentrations of air pollutants, allowing annual changes to be detected. PMID:15142770

    Syn-rift tectono-sedimentary inheritance is common in thrust-related anticlines exposed in most foreland thrust-fold belts worldwide. Inherited extensional faults provide mechanical weakness zones that typically undergo positive inversion during contraction. This unavoidably has an impact on the evolution of contractional folds. Moreover, duplexing and imbrication of thrust sheets typically produce gravitational instability of inherited fault patterns and negative inversion can be triggered in the late stages of fault-fold interaction. Such polyphase evolutionary histories can deeply influence deformation and fluid flow patterns in fault-related folds and therefore can strongly influence the distribution of structurally controlled processes such as dolomitization. In this contribution we present the results obtained from a multidisciplinary study of the tectono-sedimentary pattern and paleofluid history in carbonates exposed in the Montagna dei Fiori Anticline, at the mountain front of the Central Apennines (central Italy), where the occurrence of both syn-rift fault zones and related sediments has been previously described. Detailed mapping of the central part of the anticline, bed-perpendicular logging of syn-rift and post-rift strata, structural, petrographical, geochemical, microthermometrical, and petrophysical analyses were used to reconstruct the evolution of this anticline, starting from the pre-orogenic architecture up to its subsequent orogenic reworking. These data reveal: (1) the pre-orogenic tectono-sedimentary architecture of a folded Jurassic fault network; (2) multiple superimposition of extensional and contractional episodes of deformation on the same fault zones; (3) the presence of at least one main dolomitization episode, the timing of which is still being deciphered; (4) demonstrate the causal link between faulting and dolomitization, which favoured formation of dolostones along fault zones, particularly in the intersection/abutting areas

    This investigation examined the impact of spinal cord injury (SCI) on task-relevant processing using event-related potentials. Thirty-seven participants with chronic SCI and 37 healthy able-bodied controls were tested in this study. An auditory two-tone button press oddball discrimination paradigm was used to evoke the N100, P200, N200, and P300 components of the event-related potential. During the early sensory/perceptual stages of target stimulus processing, the SCI group showed an earlier right posterior P200 latency relative to the controls. In the later more cognitive stages, a pattern of diminished left and right posterior P300 amplitude was also evident. This was further coupled with increased false-positive errors and greater variability of response time in the SCI group. The results of this study indicate that people with SCI show disturbances in inhibitory function and alterations in both early perceptual encoding processes and in later executive functioning that engages contextual/memory-updating operations.

  7. Dissolved nitrates in the groundwater of the Cecina Plain (Tuscany, Central-Western Italy): Clues from the isotopic signature of NO3-

    International Nuclear Information System (INIS)

    Highlights: ► Nitrate pollution in the Cecina Plain (Tuscany, Italy) multi-aquifer system. ► Anthropogenic pollution by fertilizers, manure and sewage. ► δ15N–NO3 and δ18O–NO3 to recognize NO3 sources and processes. ► Monitoring of δ15N–NO3 and δ18O–NO3 for remediation programs. - Abstract: Anthropogenic NO3- is one of the most serious pollutants in the groundwaters from the multi-aquifer system of the Cecina Plain (Tuscany, central-western Italy). According to the EC Directive (91/676/CEE), the local administration of Tuscany has declared the Cecina Plain as “vulnerable by nitrates”. Determining the origin and the source(s) of NO3- contamination is an important step prior to any remediation program. In the present work a geochemical survey was carried out on 92 groundwater samples collected in June and October 2006 to highlight the natural and anthropogenic features that concur with the observed chemical composition. The geochemical facies of the water samples is dominated by Ca(Mg)–HCO3 and Ca(Mg)–SO4(Cl) and, subordinately, by Na(Ca)–Cl(SO4), likely resulting by water–rock interaction processes between meteoric-derived groundwaters with the sedimentary formations characterizing the Cecina Plain, at which ingression of seawater in the coastal area is also added. A mixing model, based on ionic ratios (NO3/Na, Cl/Na, Cl/Br), was applied to distinguish the anthropogenic sources (e.g. sewage, agriculture input) from natural sources (e.g. seawater intrusion). Selected samples were analyzed for the isotopic composition of NO3- (δ15N–NO3 and δ18O–NO3) to formulate hypotheses on its origin and the processes this component may suffer in the water system. Nitrate concentrations range from ∼0.01 to 354 mg/L. About 35% and 19% of the sampled wells in June and October 2006, respectively, had levels of NO3- higher that those recommended by the World Health Organization (<50 mg/L).

    Full Text Available Immunization of health care workers (HCWs against influenza has been associated with improvements in patient safety. The aim of this study is to assess the beliefs, attitudes, and knowledge of HCWs and health profession students regarding influenza. An anonymous questionnaire was distributed to HCWs in three local Florentine healthcare units, at Careggi University Teaching Hospital, and to students in health profession degree programs. A total of 2576 questionnaires were fully completed. A total of 12.3% of subjects responded that they were “always vaccinated” in all three of the seasonal vaccination campaigns studied (2007–2008 to 2009–2010, 13.1% had been vaccinated once or twice, and 74.6% had not received vaccinations. Although the enrolled subjects tended to respond that they were “never vaccinated,” they considered influenza to be a serious illness and believed that the influenza vaccine is effective. The subjects who refused vaccination more frequently believed that the vaccine could cause influenza and that it could have serious side effects. More than 60% of the “always vaccinated” group completely agreed that HCWs should be vaccinated. Self-protection and protecting family members or other people close to the respondent from being infected and representing potential sources of influenza infection can be considered motivating factors for vaccination. The results highlight the importance of improving vaccination rates among all HCWs through multi-component interventions. Knowledge of influenza should be reinforced.

    analyze the tectono-sedimentary and thermochronometric constraints of the Tertiary Piedmont Basin (TPB) and its adjoining orogen, the Ligurian Alps, providing new insights on the basin evolution in response to a changing geodynamic setting. The geometry of the post-metamorphic faults of the Ligurian belt as well as the fault network that controlled the Oligo-Miocene TPB deposition has been characterized through a detailed structural analysis. Three main faulting stages have been distinguished and dated thanks to the relationships among faults and basin stratigraphy and thermochronometric data. The first stage (F1, Rupelian-Early Chattian) is related to the development of extensional NNW-directed faults, which controlled the exhumation of the orogen and the deposition of nearshore clastics. During the Late Chattian, the basin drowning is marked by mudstones and turbidites, which deposition was influenced by the second faulting stage (F2). This phase was mainly characterized by NE- to ENE-striking faults developed within a transtensional zone. Since the Miocene, the whole area was dominated by transpressive tectonics. The sedimentation was represented by a condensed succession followed by a very thick, turbiditic complex. At the regional scale, this succession of events reflects the major geodynamic reorganization in the central Mediterranean region during the Oligo-Miocene times, induced by the late-collisional processes of the Alps, by the eastward migration of the Apennines subduction and by the opening of extensional basins (i. e., the Liguro-Provençal Ocean).

    Full Text Available In the last few years paleomagnetic investigations within the Apennine chain have revealed that the area is characterized by a complex pattern of deformation, not linkable to a simple and homogeneous process. In order to estimate the amount, sense and timing of vertical axis rotations within the Central Apennines, Neogene continental basins have been investigated for paleomagnetic studies. The paleomagnetic results obtained in the Plio-Pleistocene Todi basin showed that the Upper Pliocene-Lower Pleistocene evolution, associated with major dip-slip tectonics, has not involved vertical axis rotation since that time. The Anisotropy of Magnetic Susceptibility analysis (AMS, carried out on the same samples treated for paleomagnetic determination, revealed the presence of two groups of specimens characterized by different magnetic lineation directions. One direction trends NE-SW and is parallel to the orientation of the regional extension stress typical of the area. This direction is observed throughout the northern basin. The other, restricted to the southern basin, trends N-S and shows no links with the tectonic, hydrological-sedimentary conditions of the area. The results of the AMS analysis will be presented and discussed in the light of the rock magnetic results and the tectonic framework of the area.

    Full Text Available The first results of a study of monitoring species and habitats in the framework of the Life 04NAT/IT/000190 "Tutela dei siti Natura 2000 gestiti dal Corpo Forestale dello Stato" are presented. This study was carried out by the Department of Plant Biology of the University of Rome (La Sapienza and the National Forest Service. We focused the investigation on the relationships between herbaceous species and pedological parameters (humus and soil in Central-Apennine beech forests. Data have been collected through 40 phytosociological relevés, 15 soil profiles and 40 humus profiles in 40 forest plots, between March 2005 and September 2006. In this paper we presented data elaborated on a subset of 15 plots where soil profiles were available. The species of undergrowth showed different ecological requirements to some edaphic and humus parameters (pH, sand, loam, clay, organic matter, nitrogen, carbon/nitrogen ratio, Ca++, K+;thickness and carbon content of the organic layers: significant correlations have been found using Pearson correlation test. The multiple regression analysis allowed to identify the factors more influencing the species distribution: thickness of the organic layers, carbon content (% C and carbon/nitrogen ratio (C/N. Basing on the thickness of humus horizons (OL, OF, OH, and on carbon content, two species groups with different ecology have been recognized: (a nemoral species typical of shady beech stands on oligomull/dysmull/thin amphimull (0 < 1cm.; 5.7 < %C < 9.9; (b heliophilous species of more xeric stands on thick amphimull (1.25 < 11.5 cm.; 9.9 < %C < 13.7. The relationships among species and soil parameters and humus forms allow to recognize small differences within a homogeneous habitat and therefore they can provide management indications also at micro-scale level.

    This study aimed to assess the effects of forest management on the occurrence of accelerated soil erosion by water. The study site is located in a mountainous area of the Italian Central Apennines. Here, forest harvesting is a widespread forestry activity and is mainly performed on the moderate to steep slopes of the highlands. Through modeling operations based on data on soil properties and direct monitoring of changes in the post-forest-harvesting soil surface level at the hillslope scale, we show that the observed site became prone to soil erosion after human intervention. Indeed, the measured mean soil erosion rate of 49 t ha- 1 yr- 1 for the harvested watershed is about 21 times higher than the rate measured in its neighboring undisturbed forested watershed (2.3 t ha- 1 yr- 1). The erosive response is greatly aggravated by exposing the just-harvested forest, with very limited herbaceous plant cover, to the aggressive attack of the heaviest annual rainfall without adopting any conservation practices. The erosivity of the storms during the first four months of field measurements was 1571 MJ mm h- 1 ha- 1 in total (i.e., from September to December 2008). At the end of the experiment (16 months), 18.8%, 26.1% and 55.1% of the erosion monitoring sites in the harvested watershed recorded variations equal or greater than 0-5, 5-10 and > 10 mm, respectively. This study also provides a quantification of Italian forestland surfaces with the same pedo-lithological characteristics exploited for wood supply. Within a period of ten years (2002-2011), about 9891 ha of coppice forest changes were identified and their potential soil erosion rates modeled.

    Full Text Available Abstract Background The district of Manang (2000 – 6000 m is located in the Central Himalayas, Nepal. The majority of local inhabitants of the area are Gurungs, of Tibetan origin. The remoteness of the region has resulted in continued use of plants as medicine in an area where the ethnobotany has sparsely been documented. Methods Interviews were conducted with amchi (Tibetan medicinal practitioners, local healers (including priests locally known as 'lamas', plant traders, and knowledgeable villagers (including herders regarding local plant names and their medicinal uses during several field visits (2002–2005. When convenient to the locals, a jungle or forest walk was done with the healers, allowing for both plant collection and detailed information gathering. Results This present research documented 91 ethnomedicinal plant species, belonging to 40 families under 73 genera, and 45 new ethnomedicinal plant species are added. These 91 locally used medicinal plants are found to treat 93 ailments. This study provides information on 45 plant species previously unknown for their medicinal uses in Manang. The indication for use, mode of preparation, dose and administration of medicine are described in detail for each species. Conclusion This wealth of ethnobotanical knowledge persists, and is being transferred to the next generation in some areas in upper Manang, in a country where this is often not the case. The senior amchi of the area (Karma Sonam Lama, who has been practicing Tibetan medicine for three generations, feels that it is of utmost importance to conserve the traditional healing system and to pass his knowledge on to the local community about the importance of medicinal plants. He hopes that this will lead to the conservation and sustainable management of medicinal plants in the villages. Over the duration of this research, the prices of several rare medicinal plants of Manang increased dramatically, highlighting both the scarcity and

    The detection of detached nearshore wedges formed in response to relative sea-level drops is considered one of the hottest topics in sequence stratigraphic analysis due to their importance as reservoir analogues. In fact, they usually constitute sandy and porous bodies generally encased in impermeable clay, thus presenting a good potential as traps for fluids. This paper focuses on the sequence stratigraphic analysis of the Pliocene deposits cropping out in the central-southern sector of the Siena Basin (Tuscany, Italy), a post-collisional basin of the Northern Apennines. The exposed sedimentary succession was investigated through a detailed sedimentological and stratigraphic approach, integrated by biostratigraphic analyses, aimed at a better characterization of the infilling history of this sector of the basin. Specifically, this study revealed the occurrence of repeated facies shifts that allowed the identification of two depositional sequences. In detail, a thick sand-rich body far from the basin margins, and previously considered as a turbiditic lobe, has been reinterpreted as formed in a nearshore setting during a fall in relative sea level. This body is totally encased in offshore clay, and due to the lack of physical connection with the related HST deposits, it has to be considered as a detached forced-regressive wedge. The present work led to the recognition of some sedimentological and stratigraphic features typical of falling stage systems tract deposits (e.g. presence of intrabasinal recycled materials, sedimentological evidence of a pre-existing fluvial network subsequently eroded) that can provide useful clues for the identification of detached forced-regressive nearshore wedges in core studies and poorly exposed settings.

    Full Text Available The stable oxygen and carbon isotopic composition of ostracod valves is the result of the interaction of several variables. Understanding and identifying the biological and ecological factors influencing the life of these animals improves the interpretation of isotopical data, and leads to better paleoenvironmental reconstructions. Ostracod biostratigraphy and determinations of oxygen and carbon stable isotopes on ostracod valves were carried out on a short sequence of the Last Glacial Maximum from Lake Albano (Central Italy. The oxygen isotopic composition of adults of Candona neglecta ranged between 0.5‰ and 1.5‰, and in Ilyocypris bradyi between –2‰ and –0.5‰ . Isotopic values from adults of C. neglecta fell within the range –1.5‰ to –0.8‰ when corrected for vital effect. The carbon isotopic signal ranged from 9.4‰ to 10.8‰ in adults and juveniles of C. neglecta, and from 9.8‰ to 11.3‰ in I. bradyi. Differences between left/right valve and gender were negligible, whereas there appeared to be a marked influence of life stage and species-specific factors related to vital effect and differences in microhabitat and seasonality. We combined analyses on carbon and oxygen isotopes with information deriving from ostracod ecology to reconstruct short term oscillations in past lake water level. Seasonal changes in either the temperature or the isotopic composition of the lake water were also identified. Relatively high δ18O values in ostracod valves were probably associated with the lake location and source of moisture, while high δ13C values were most probably related to the input of volcanic CO2 into the lake.

    Abrupt climate change in the past is thought to have disrupted societies by accelerating environmental degradation, potentially leading to cultural collapse. Linking climate change directly to societal disruption is challenging because socioeconomic factors also play a large role, with climate being secondary or sometimes inconsequential. Combining paleolimnologic, historical, and archaeological methods provides for a more secure basis for interpreting the past impacts of climate on society. We present pollen, non-pollen palynomorph, geochemical, paleomagnetic and sedimentary data from a high-resolution 2700 yr lake sediment core from central Italy and compare these data with local historical documents and archeological surveys to reconstruct a record of environmental change in relation to socioeconomic history and climatic fluctuations. Here we document cases in which environmental change is strongly linked to changes in local land management practices in the absence of clear climatic change, as well as examples when climate change appears to have been a strong catalyst that resulted in significant environmental change that impacted local communities. During the Imperial Roman period, despite a long period of stable, mild climate, and a large urban population in nearby Rome, our site shows only limited evidence for environmental degradation. Warm and mild climate during the Medieval Warm period, on the other hand, led to widespread deforestation and erosion. The ability of the Romans to utilize imported resources through an extensive trade network may have allowed for preservation of the environment near the Roman capital, whereas during medieval time, the need to rely on local resources led to environmental degradation. Cool wet climate during the Little Ice Age led to a breakdown in local land use practices, widespread land abandonment and rapid reforestation. Our results present a high-resolution regional case study that explores the effect of climate change on

  19. Comparison of Arundo donax L. and Miscanthus x giganteus in a long-term field experiment in Central Italy: Analysis of productive characteristics and energy balance

    International Nuclear Information System (INIS)

    Miscanthus x giganteus (miscanthus) and Arundo donax L. (giant reed) are two perennial crops which have been received particular attention during the last decade as bioenergy crops. The main aim of the present study was to compare the above-ground biomass production and the energy balance of these perennial rhizomatous grasses in a long-term field experiment. The crops were cultivated from 1992 to 2003 in the temperate climate of Central Italy with 20,000 plants ha-1, 100-100-100 kg N, P2O5, K2O per hectare, and without irrigation supply. For each year of trial, biomass was harvested in autumn to estimate biometric characteristics and productive parameters. Besides, energy analysis of biomass production was carried out determining energy output, energy input, energy efficiency (output/input) and net energy yield (output-input). Results showed high above-ground biomass yields over a period of 10 years for both species, with better productive performances in giant reed than in miscanthus (37.7 t DM ha-1 year-1vs 28.7 t DM ha-1 year-1 averaged from 2 to 12 years of growth). Such high yields resulted positively correlated to number of stalks (miscanthus), plant height and stalk diameter (giant reed). Moreover, these perennial species are characterised by a favourable energy balance with a net energy yield of 467 and 637 GJ ha-1 (1-12 year mean) for miscanthus and giant reed respectively. With such characteristics, both grasses could be proposed as biomass energy crops in Southern Europe with a significant and environmentally compatible contribution to energy needs

    Matupás are floating vegetation islands found in floodplain lakes of the central Brazilian Amazon. They form initially from the agglomeration of aquatic vegetation, and through time can accumulate a substrate of organic matter sufficient to grow forest patches of several hectares in area and up to 12 m in height. There is little published information on matupás despite their singular characteristics and importance to local fauna and people. In this study we document the traditional ecological knowledge of riverine populations who live near and interact with matupás. We expected that their knowledge, acquired through long term observations and use in different stages of the matupá life cycle, could help clarify various aspects about the ecology and natural history of these islands that field biologists may not have had the opportunity to observe. Research was carried out in five riverine communities of the Amanã Sustainable Development Reserve (Brazil). Semi-structured interviews were conducted with 45 inhabitants in order to register local understandings of how matupás are formed, biotic/abiotic factors related to their occurrence, the plants and animals that occur on them, their ecological relevance, and local uses. Local people elucidated several little-known aspects about matupá ecology, especially regarding the importance of seasonal dynamics of high/low water for matupás formation and the relevance of these islands for fish populations. Soil from matupás is especially fertile and is frequently gathered for use in vegetable gardens. In some cases, crops are planted directly onto matupás, representing an incipient agricultural experiment that was previously undocumented in the Amazon. Matupás are also considered a strategic habitat for fishing, mainly for arapaima (Arapaima gigas). The systematic study of traditional ecological knowledge proved to be an important tool for understanding this little-known Amazonian landscape. PMID:25837281

    The objective of this study was to conduct an evaluation of Reach Out Central (ROC), an online gaming program designed to support the mental health of people aged 16-25. The evaluation sought to determine the benefit of playing ROC on alcohol use, use of coping strategies, psychological distress, resilience and satisfaction with life. Changes in mental health literacy, mental health stigma and willingness to seek help and program satisfaction were also investigated. A single group (N = 266) quasi-experimental repeated measures (pre-, post-program, 2-month follow-up) design was employed. The results demonstrated positive improvements across all outcome measures for females; however, a non-significant worsening effect was observed for males on seeking support, avoidance and resilience. Improvements for both genders were observed on mental health literacy and help-seeking. However, literacy levels and help-seeking were significantly higher, and stigma significantly lower for females. Program satisfaction ratings were high irrespective of gender. Although some inconsistencies between genders were noted, ROC appears to enhance protective factors for the prevention or early intervention of mental health disorders. The results of this study need to be viewed with its limitations in mind, specifically, the use of an open trial methodology and the small number of male participants. PMID:20150530

    The Abruzzi region is located in the Central Apennines Neogene fold-and-thrust belt and has one of the highest seismogenic potential in Italy, with high and diffuse crustal seismicity related to NE-SW oriented extension. In this study, we investigate the detailed spatial variation in shear wave splitting providing high-resolution anisotropic structure beneath the L'Aquila region. To accomplish this, we performed a systematic analysis of crustal anisotropic parameters: fast polarization direction (ϕ) and delay time (δt). We benefit from the dense coverage of seismic stations operating in the area and from a catalogue of several accurate earthquake locations of the 2009 L'Aquila seismic sequence, related to the Mw 6.1 2009 L'Aquila main shock, to describe in detail the geometry of the anisotropic volume around the active faults that ruptured. The spatial variations both in ϕ and δt suggest a complex anisotropic structure beneath the region caused by a combination of both structural- and stress-induced mechanisms. The average ϕ is NNW-SSE oriented (N141°), showing clear similarity both with the local fault strike and the SHmax. In the central part of the study area fast axes are oriented NW-SE, while moving towards the northeastern and northwestern sectors the fast directions clearly diverge from the general trend of NW-SE and rotate accordingly to the local fault strikes. The above-mentioned fault-parallel ϕ distribution suggests that the observed anisotropy is mostly controlled by the local fault-related structure. Toward the southeast fast directions become orthogonal both to strike of the local mapped faults and to the SHmax. Here, ϕ are predominantly oriented NE-SW; we interpret this orientation as due to the presence of a highly fractured and overpressurized rock volume which should be responsible of the 90° flips in ϕ and the increase in δt. Another possible mechanism for NE-SW orientation of ϕ in the southeastern sector could be ascribed to the

    From March to September 2009 a dense velocimetric network was installed in correspondence of Narni, a little village in central Italy, built on the top of a massive limestone ridge. The network was planned with the aim to investigate possible local site effects due to the morphology of the ridge, characterized by slopes ranging from 22° to 35° and a maximum difference of quota between top and bottom of 230 m. Three stations were installed at the base of the hill and other 7 monitored the crest. A remarkable dataset was obtained, composed by about 700 earthquakes, the great amount of which occurred after the 06th April 2009, Mw 6.3, L'Aquila earthquake. Site amplifications related to the ridge morphological features were investigated through empirical techniques with and without reference site, computing Spectral Standard Ratio, SSR and Horizontal to Vertical spectral ratio, HVSR. Directional spectral analyses were also performed . The agreement between the results coming from HVSR and SSR techniques allows us to assess with reliability a clear amplification effect for frequencies ranging between 3 and 5 Hz for all stations installed on the crest: in particular, SSR results show an amplification level with respect to the reference station up to 4.5. The highest amplification level (almost double) were observed when the direction perpendicular to the main elongation of the ridge is taken into account. Finally, considering the L'Aquila events with Mw > 4.5 and merging the information coming from the reference and non-reference site techniques, it was possible to recognize further amplification effects, at frequency lower than 1 Hz, probably related not to the morphology of the area but to source and/or polarization effects. Bidimensional numerical simulations were then computed in order to compare the results coming from the experiment with those obtained through numerical modeling. A hybrid finite-boundary element method based on code named HYBRID has been used for

    Babesia caballi and Theileria equi are tick-borne pathogens, etiological agents of equine piroplasmosis that affect different species of Equidae causing relevantly important direct and indirect losses. A field study was conducted to evaluate the distribution of the equine piroplasms in an area of Central-Southern Italy and to identify correlated risk factors. Serum samples of 673 asymptomatic horses were collected during spring-summer of 2013 to estimate the seroprevalence of the parasites within the study area using T. equi and B. caballi Antibody test kit (VMRD(®), Inc, Pullman, WA, USA). The 273 seropositive samples were subsequently tested by real time PCR to verify the presence of the genome of the piroplasms, indicative of the carrier status of the subjects. The variables chosen to identify which were the risk factors associated with the serological and PCR-positivity for each of the equine piroplasms were the following: gender, age, breed, access to pasture, altitude, land cover, climatic zone, soil type and province location (coastal/inland). The resulting overall seroprevalence for T. equi was 39.8% (268/673) and for B. caballi was 8.9% (60/673) while 70.3% of the PCR tested samples (185/263) were positive for T. equi and 10.3% (27/263) for B. caballi. The univariate and multiple logistic regression models were used to assess the association of the risk factors with the different outcomes. The risk factors found to be associated with T. equi seropositivity were gender, age, breed, access to pasture, land cover, soil type and province location, while those associated with PCR-positivity were age, soil type and province location. As the number of B. caballi seropositive subjects was limited, the multiple logistic regression model was performed only for the PCR-positive status, identifying climatic zone and soil type as the sole risk factors. In the study area, a major diffusion of T. equi, in terms of seroprevalence and PCR-positivity was present when

    This study reviews the thickness statistics of non-channelized turbidites from four tertiary basins of Central-Northern Apennines (Italy), where bed geometry and sedimentary character have been previously assessed. Though very different in terms of size and, arguably, character of feeder system, these basins share a common stratigraphic evolution consisting in transition from an early ponded to a late unconfined setting of deposition. Based on comparison of thickness subsets from diverse locations and stratigraphic heights within the studied turbidite fills, this paper seeks to answer the following questions: i) how data collection procedures and field operational constraints (e.g. measure location, outcrop quality, use of thicknesses data from single vs. multiple correlative sections, stratigraphic thickness of the study interval) can affect statistics of sample data? ii) how depositional controls of confined vs. unconfined turbidite basins can result in different thickness-frequency distributions?; and iii) is there in thickness statistics a 'flow confinement' signature which can be used to distinguish between confined and unconfined turbidites? Results suggest that: i) best practices of data collection are crucial to a meaningful interpretation of sample data statistics, especially in presence of stratigraphic and spatial trends of turbidite bed thickness; ii) a systematic bias against cm-thick Tcd Bouma sequence turbidites exists in sample data, which can result in the low-end tail of empirical thickness-frequency distributions to depart significantly from the actual distribution of turbidite thickness; and iii) thickness statistics of beds starting with a basal Ta/Tb Bouma division bear a coherent relationship to the transition from ponded to unconfined depositional settings, consisting in reduction of variance and mean and, consequently, parameters, or even type, of best fit model distribution. This research highlights the role of flow stripping, sediment by

    This contribution describes the technical characteristics and the preliminary calibration of a rainfall simulator recently installed by the Department of Agricultural, Food and Environmental Sciences (Perugia University) at the Masse experimental station located 20 km south of Perugia, in the region of Umbria (central Italy). The site includes some USLE plots of different length λ = 11 and 22 m and width w = 2, 4 and 8 m, oriented parallel to a 16 % slope and kept free of vegetation by frequent ploughing. Since 2008, the station enabled to collect data from more than 80 erosive events, that were mainly used to investigate the relationship between rainfall characteristics and soil loss. The relevant soil loss variability that characterizes erosive storm events with similar overall characteristics (duration and/or depth) can be explained by the different rainfall profile of erosive storms and by the different antecedent soil aggregate stability. To analyse in more detail these aspects, recently, the Masse experimental station has been equipped with a semi-portable rainfall simulator placed over two micro-plots of 1x1 m each, having the same topographic and pedologic conditions of the adjacent USLE plots. The rainfall simulator consists of four full-cone spray nozzles for each micro-plot, placed at the angles of a 0.18-m square, centred over the plot at a height of 2.7 m above the ground. The operating pressure is regulated by pressure regulating valves and checked by pressure gauges mounted in correspondence of each nozzle. An electronic control unit regulates the start and stop of the inlet solenoid valves. A range of rainfall intensities can be achieved, by activating different combinations of nozzles (15 different intensities) also during the same simulation trial. The particular design of the plots allows to collect separately the runoff volume deriving from the plots and the water volume fallen outside of the plot. In this way it is possible to derive, by

    Full Text Available Although attention on crayfish diseases has recently proliferated, the focus is mainly on a single host-parasite relationship rather than analyzing the entire mycoflora, probably due to the fact that (1 some diseases are occasional (pathogens of which are of difficult collection and (2 economic impact is more relevant in aquaculture (i.e., a controlled environment where only few parasites occur than in natural conditions. Contrary to this viewpoint, fungal ectoparasites assume a great importance since they are integral components in shaping community, ecosystem structure, and energy flow. Here we described the fungal species co-occurrence patterns (species segregation/ aggregation using null models comparing the occurrence frequencies of ectosymbiots through host individuals with those expected by chance. Non-indigenous crayfish species like Procambarus clarkii allow to observe phenomena of competitive exclusion (segregation or mutualism (aggregation amongst fungi. We analyzed the fungal species occurrence on 86 host crayfish monthly collected from June 2007 to June 2008 in the Lake Trasimeno (Central Italy. A total of 29 fungal taxa were detected. Taxa showed a particular fungal assemblage with a great species variation depending on sampling month and crayfish sex, size, and body region. In particular, fungal species showed different occurrence patterns in both richness and segregation/ aggregation. The fungal community shows a non-random structure not in all cases, with the majority of tests indicating segregation, not aggregation of ectosymbiontic species on hosts. The non-random patterns of fungal co-occurrence in some cases suggest that some temporally or spatially variable factors are responsible for the establishment of the mycoflora community assemblage. We also detected temporal differences in fungal co-occurrences patterns. Regarding seasonal samples, the same analyses showed a competitive structure only in the sub-communities found on

    A particular aspect of demographic behavior among young people in Italy is postponement of entering first union. High youth unemployment, a tense housing situation, and a passive welfare state are currently creating a precarious economic situation, in which most young adults are unable to choose cohabitation. Thus, not surprisingly, previous studies found evidence that in Italy cohabitation was only a choice for people who were economically independent. Also of interest is that the percentage...

    A revision of the available seismic reflection survey in the off-shore part of the northern Latium (central Italy) has been accomplished to better understand the deep structural setting of this area. Previous works performed in the last twenty years have compared the on-shore outcrops of cretaceous flyschoid and Plio-Pleistocene marine sedimentary units with shallow off-shore seismic reflection data (1/1,5 msec twt maximum), while the deep structural setting of calcareous basement of Tuscan units have been poorly analysed. The stratigraphy of the area is well constrained by a deep well, which goes through the entire sedimentary succession. Other geological constraints are provided by a discrete amount of deep wells in the on-shore part of the study area and by a voluminous bibliography, in which many authors tried to correlate this units to the tectonic units described in the central and northern part of the Apennines. The stratigraphy could be divided in four main groups of units; from top to bottom: Plio-Pleistocene marine deposits, Cretaceous Liguride deep-water units, Jurassic Tuscan pelagic deposits, and a Triassic evaporitic formation. Even volcanic intrusive bodies (Tolfa-Ceriti-Manziana dome complexes) are present in the on-shore part. The emplacement of this bodies generally caused a further overprint on the different deformation phases that affected this area. Seismic reflection data analysis show that this area was affected by at least three deformational phases. After the deposition of the Tuscan and Liguride sedimentary units, the area underwent: i) an initial compressional phase associated to the Alps-Northern Apennine chain build up, with formation of compressional features as regional thrusts, back-thrusts and fold structures. These structures are clearly visible in the deep Tuscan and Liguride units setting; ii) a successive extensional deformation phase related to the spreading of the Tyrrhenian Sea, starting in the late Miocene times. This caused

    Through prepaid compulsory insurance managed by the central government, Italy's National Health Service (NHS) provides full coverage, free accessibility, and no or limited copayment by individuals when receiving health services. Although Italy spends less than other countries on health care (product), the present NHS faces considerable difficulties, and its performance regarding quality, outcome, and spending has come under question. ICUs account for mix, and outcomes when compared with data from other countries. Important changes in the financial and institutional framework of the NHS are underway, yielding an unpredictable scenario for the future. Innovations focus mostly on cost containment and quality initiatives. These innovations will likely produce a new health service in which regions will have a more important role than in the past. Actions planned in a large Italian region by the local government are used as an example to explain the potential impact of this new trend on critical care medicine. PMID:8087596

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

    This paper focuses on the chemical and isotopic features of dissolved gases (CH4 and CO2) from four meromictic lakes hosted in volcanic systems of Central-Southern Italy: Lake Albano (Alban Hills), Lake Averno (Phlegrean Fields), and Monticchio Grande and Piccolo lakes (Mt. Vulture). Deep waters in these lakes are characterized by the presence of a significant reservoir of extra-atmospheric dissolved gases mainly consisting of CH4 and CO2. The δ13C-CH4 and δD-CH4 values of dissolved gas samples from the maximum depths of the investigated lakes (from -66.8 to -55.6 ‰ V-PDB and from -279 to -195 ‰ V-SMOW, respectively) suggest that CH4 is mainly produced by microbial activity. The δ13C-CO2 values of Lake Grande, Lake Piccolo, and Lake Albano (ranging from -5.8 to -0.4 ‰ V-PDB) indicate a significant CO2 contribution from sublacustrine vents originating from (1) mantle degassing and (2) thermometamorphic reactions involving limestone, i.e., the same CO2 source feeding the regional thermal and cold CO2-rich fluid emissions. In contrast, the relatively low δ13C-CO2 values (from -13.4 to -8.2 ‰ V-PDB) of Lake Averno indicate a prevalent organic CO2. Chemical and isotopic compositions of dissolved CO2 and CH4 at different depths are mainly depending on (1) CO2 inputs from external sources (hydrothermal and/or anthropogenic); (2) CO2-CH4 isotopic exchange; and (3) methanogenic and methanotrophic activity. In the epilimnion, vertical water mixing, free oxygen availability, and photosynthesis cause the dramatic decrease of both CO2 and CH4 concentrations. In the hypolimnion, where the δ13C-CO2 values progressively increase with depth and the δ13C-CH4 values show an opposite trend, biogenic CO2 production from CH4 using different electron donor species, such as sulfate, tend to counteract the methanogenesis process whose efficiency achieves its climax at the water-bottom sediment interface. Theoretical values, calculated on the basis of δ13C-CO2 values, and

    Risk management of slow landslides requires both the assessment of slope stability conditions and the analysis of the dynamic evolution in terms of displacement, velocity or acceleration during the deformation phase. To this purpose, we analysed the kinematical evolution of a slow landslides through a numerical model implemented in Finite Element Environment (FEE) and compared with monitoring data based on DInSAR interferometry technique and conventional inclinometric investigation. In our study we analyse the Ivancich slow landslide (Assisi, Central Italy). The landslide body is formed of detritus (or debris) material sliding on a arenaceous marl substratum, with a thin shear band detected using borehole and inclinometric data, at depth ranging from 20 to 60 m. Specifically, we considered the active role of this shear band in the control of the landslide evolution process. Ground surface displacement measurements have been also retrieved via an advanced space-based Differential SAR interferometry analysis. ERS-1/2 and ENVISAT SAR images taken in the 1992-2010 period have been used to generate long time-series showing the temporal evolution of surface movements of the unstable slope, that indicate different displacement rates for the various portions of the landslide body. A large field monitoring dataset of the landslide process, including at-depth piezometric and inclinometric measurements acquired in the last decade all over the landslide body, was available to us. The piezometric data do not show appreciable variation of the pore water pressures at the level of the sliding surface. We performed a two-dimensional time-dependent Finite Element Model (FEM) of the active ground deformation field aimed at simulating the kinematical evolution of the different sectors of the unstable mass. In particular, a deviatoric creep law, accounting for a time dependent shear deformation over constant deviatoric stress, has been used to describe the shear band behavior. An

    Natural soundscape has always constituted a reference in cognitive and emotional processes. The imitation of natural sounds contributed to the origin of the verbal language, which has been then subjected to an even more refined process of abstraction throughout history. The musical language also evolved along the same path of imitation. Among the many sonic elements of a natural environment, the stridulation of crickets is one of the most consistent for its timbre, articulation, diffusion and intrinsic emotional power. More than 900 species of crickets, in fact, have been described. They can be found in all parts of the world with the exception of cold regions at latitudes higher than 55° North and South. Among the many species we're working on (Order Orthoptera and Suborder Ensifera), we refer here of a comparison between the morphology of the acoustic emission systems and the corresponding waveforms/spectral patterns of sound in three widespread species from central Italy: Gryllus Bimaculatus, Acheta Domesticus (Gryllidae), and Ruspolia Nitidula (Conocephalidae). The samples of the acoustic apparatus of the target individuals, stored in ethanol, were observed under a Field Emission Gun Environmental Electron Scanning Microscope (FEG-ESEM, Quanta 200, FEI, The Netherlands). The use of this type of microscope allowed to analyze the samples without any kind of manipulation (dehydration and/or metallization), while maintaining the morphological features of the fragile acoustic apparatus. The observations were made with different sensors (SE: secondary-electron sensor and BSE: backscattered-electron sensor), and performed at low-medium vacuum with energies varying from c.ca 10 to 30kV. Male individuals have an acoustic apparatus consisting in two cuticular structures (tegmina) positioned above wings, while both male and females have receiving organs (tympanum) in forelegs. Stridulation mechanism is produced when the file and the scraper (plectrum) scrub one another

Besides, the central Italy landscape is characterized by a high level of fragmentation and heterogeneity It requires stringent Remote sensing technical features in terms of spectral, geometric and temporal resolution to aimed at supporting applications for precision viticulture. In response to the needs of the Italian grape and wine industry for an evaluation of precision viticulture technologies, the DISAFRI (University of Tuscia) and the Agricultural Research Council - Oenological research unit (ENC-CRA) jointly carried out an experimental study during the year 2008. The study was carried out on 2 areas located in the town of Velletri, near Rome; for each area, two varieties (red and white grape) were studied: Nero d'Avola and Sauvignon blanc in first area , Merlot and Sauvignon blanc in second. Remote sensing data were acquired in different periods using a low cost multisensor Airborne remote sensing platform developed by DISAFRI (ASPIS-2 Advanced Spectroscopic Imager System). ASPIS-2, an evolution of the ASPIS sensor (Papale et al 2008, Sensors), is a multispectral sensor based on 4 CCD and 3 interferential filters per CCD. The filters are user selectable during the flight and in this way Aspis is able to acquire data in 12 bands in the visible and near infrared regions with a bandwidth of 10 or 20 nm. To the purposes of this study 7 spectral band were acquired and 15 vegetation indices calculated. During the ripeness period several vegetative and oenochemical parameters were monitored. Anova test shown that several oenochemical variables, such as sugars, total acidity, polyphenols and anthocyanins differ according to the variety taken into consideration.

    Late Miocene intrusive magmatism of the Island of Elba, Tuscany (central Italy), consists of stocks, laccoliths, sills, and dikes showing dominant monzogranite and granodiorite compositions, with minor leucogranitic dike-sill complexes, aplites and pegmatites. A few mafic rocks occur as dikes, and as microgranular enclaves hosted inside the main intrusions. The Elba magmatism belongs to the Tuscan Magmatic Province, an 8.5 to 0.3 Ma old association of mafic to felsic rocks, of mantle and crustal origin, cropping out in Tuscany and northern Latium. Major and trace element abundances of Elba rocks are extremely variable, testifying to complex origin and evolutionary history for magmas. 87Sr/86Sr (~ 0.708-0.723) and 143Nd/144Nd (~0.5121-0.5124) are close or within the field of upper continental crust, with mafic dikes showing the lowest Sr- and the highest Nd-isotope ratios. Petrological, geochemical and textural data of Elba igneous rocks are better explained by invoking a leading role for multiple mixing processes between crust-derived felsic magmas and mafic-intermediate melts of ultimate mantle origin, accompanied by fractional crystallisation. Proxies of crustal anatectic melts are represented by some highly radiogenic-Sr rocks from northern Monte Capanne pluton. Crustal magmas were formed by melting of sedimentary rocks, likely metagreywakes, at pressures exceeding 0.3 GPa. Mafic-intermediate magmas have calcalkaline to shoshonitic compositions and originated in an anomalous mantle, moderately contaminated by siliceous sediments. Selective enrichments in Sr, Ba and LREE are shown by some intermediate rocks (Orano dikes), revealing the occurrence of a distinct magma type at Elba. Similar compositions are also observed at Capraia island, San Vincenzo and Campiglia (southern Tuscany), suggesting a regional relevance for this magma type. Sr-Ba-LREE-rich rocks do not show obvious genetic relationships with other Tuscany magmas and may represent a distinct end

    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.

  5. Nuclear decommissioning in Italy

    International Nuclear Information System (INIS)

    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

    Four hundred bridges cross the labyrinth of canals that form the 120 islands of Venice, situated in a saltwater lagoon between the mouths of the Po and Piave rivers in northeast Italy. All traffic in the city moves by boat. Venice is connected to the mainland, 4 kilometers (2.5 miles) away, by ferries as well as a causeway for road and rail traffic. The Grand Canal winds through the city for about 3 kilometers (about 2 miles), dividing it into two nearly equal sections. According to tradition, Venice was founded in 452, when the inhabitants of Aquileia, Padua, and several other northern Italian cities took refuge on the islands of the lagoon from the Teutonic tribes invading Italy at that time.This image was acquired on December 9, 2001 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.Dr. Anne Kahle at NASA

  8. Contrasting alluvial architecture of Late Pleistocene and Holocene deposits along a 120-km transect from the central Po Plain (northern Italy)

    2016-07-01

    High-resolution investigation of a ~ 120-km-long transect along the course of the modern Po River, northern Italy, revealed marked changes in alluvial architecture across the Pleistocene-Holocene boundary. Along the whole transect, a 20- to 30-m thick sheet-like succession of Late Pleistocene fluvial sands is invariably overlain by silt and clay deposits, with isolated fluvial bodies of Holocene age (architecture: well-drained floodplain deposits are transitional at distal locations to increasingly organic, poorly drained floodplain to swamp facies associations. Thick paludal facies extend continuously up to 60 km landward of the Holocene maximum marine ingression, about 90 km from the modern shoreline. Based on 28 radiocarbon dates, the abrupt change in lithofacies and channel stacking pattern occurred at the transition from the last glacial period to the present interglacial, under conditions of rapid sea-level rise. The architectural change from amalgamated, Late Pleistocene sand bodies to overlying, mud-dominated Holocene units represent an example of chronologically well-constrained fluvial response to combined climate and relative sea-level change. The overall aggradational stacking pattern of individual channel-belt sand bodies indicates that high subsidence rates continuously created accommodation in the Po Basin, even during phases of falling sea level and lowstand.

    Full Text Available Italian university students were investigated for: sources of information about HIV, knowledge of HIV risk behaviours, as well as sexual behaviours and condom use. A self completed anonymous questionnaire was administered to 430 university students in Campobasso, Italy (mean age 23,1; males 35,8%. Although TV, radio and the printed press were the most common sources of HIV information (>60% of respondents, most respondents preferred to receive information from physicians or resource centres (50 and 51%. Most students (>97% were aware that specific sexual behaviours (unprotected vaginal or anal intercourse and sharing of needles with illegal injecting drug users could transmit HIV. Most students (>50% did not regularly use condoms (despite understanding their protective effect, and continued to engage in behaviours considered risky. Males were significantly more likely than females to engage in vaginal sex (84 vs. 67% or anal sex (37 vs. 13% with both regular and casual partners. Although knowledge of HIV in itself is not enough to produce behaviour change, increases in students’ levels of knowledge may be useful.

    A prerequisite to constrain fault-based and time-dependent earthquake rupture forecast models is to acquire data on the past large earthquake frequency on an individual seismogenic source and to compare all the recorded occurrences in the active fault-system. We investigated the Holocene seismic history of the Pizzalto normal fault, a 13 km long fault segment belonging to the Pizzalto-Rotella-Aremogna fault system in the Apennines (Italy). We collected 44 samples on the Holocene exhumed Pizzalto fault plane and analyzed their 36Cl and rare earth elements content. Conjointly used, the 36Cl and REE concentrations show that at least 6 events have exhumed 4.4 m of the fault scarp between 3 and 1 ka BP, the slip per event ranging from 0.3 to 1.2 m. No major events have been detected over the last 1 ka. The Rotella-Aremogna-Pizzalto fault system has a clustered earthquake behaviour with a mean recurrence time of 1.2 ka and a low to moderate probability (ranging from 4% to 26%) of earthquake occurrence over the next 50 years. We observed similarities between seismic histories of several faults belonging to two adjacent fault systems. This could again attest that non-random processes occurring in the release of the strain accumulated on faults, commonly referred to as fault interactions and leading to apparent synchronization. If these processes were determined as being the main parameter controlling the occurrence of earthquakes, it would be crucial to take them into account in seismic hazard models.

    Full Text Available The rich orthophragminid assemblages from the upper Thanetian and lower Ypresian of Turkey are discussed together with the coeval faunas from Spilecco (N Italy and Beloslav (Bulgaria. Their taxonomy, evolution and biozonation in the Western Tethys are revised. Our biometric study is based mainly on a large number of equatorial sections of megalospheric individuals. We present the emended description of Discocyclina seunesi, D. tenuis, Orbitoclypeus multiplicatus, O. bayani and Asterocyclina taramellii. A new species, Nemkovella stockari is introduced. The evolutionary lineages of Discocyclina seunesi, Orbitoclypeus multiplicatus and O. bayani are restored for the first time by using the consistent size-increase of the megalospheric embryon that also allowed introducing some new subspecies (Discocyclina seunesi beloslavensis, D. s. karabuekensis, Orbitoclypeus multiplicatus kastamonuensis, O. bayani kurucasileensis and O. munieri ponticus. By owing the most complete record of Thanetian and early Ypresian orthophragmines from the Western Tethys (using also data from SW France and the Crimean Peninsula we could reconstruct their early evolution. The chronostratigraphical position of some localities was ascertained from planktic and larger benthic foraminifera, as well as calcareous nannoplankton. In the updated orthophragminid zonation (zones are marked by OZ, OZ 1a corresponds to the early Thanetian, OZ 1b to the middle Thanetian. They are distinguished on the base of the evolution of Discocyclina seunesi. In these zones, only two unribbed species of Discocyclina and Orbitoclypeus each are present. Ribbed Orbitoclypeus, genus Asterocyclina and Nemkovella appeared in the redefined OZ 2 zone belonging to the late Thanetian. Discocyclina archiaci and D. dispansa substituted D. seunesi at about the Paleocene/Eocene boundary. The early Ypresian can be subdivided into the OZ 3 and 4 zones that can be distinguished from each other by the different

    We report on the paleomagnetism (39 new sites) of Gran Sasso, an indenter-controlled salient of the external central Apennines formed by two orthogonal limbs. We find that Gran Sasso is a complex salient, paleomagnetically corresponding to neither a nonrotating nor an oroclinal end-member. Data from the core of the arc show that the indenter itself did not undergo any rotation. Conversely, rotations of variable magnitude and sign are observed along the curveshaped thrust fronts.

    During the dismembering of the Pangea supercontinent, middle-late Triassic sub-volcanic alkaline rocks were emplaced in central Sicily. These rocks have an alkali basaltic composition and show OIB-like incompatible element patterns in primitive mantle-normalized diagrams (e.g., enrichments in HFSE and LREE coupled with high HFSE/LILE ratios), as well as slightly positive \\varepsilon_{Nd} values. Only subtle effects of crustal contamination at shallow depths emerge from geochemical data. These characteristics are very different compared with the Permian calcalkaline magmas from elsewhere in SW Europe still carrying the geochemical signature of modifications related to the Variscan orogeny. The mineralogical, geochemical and isotopic compositions of the investigated samples from central Sicily are also different from the coeval shoshonitic volcano-plutonic formations of Southern Alps (Dolomites). The incompatible element composition and Nd isotopic ratios are consistent with low-degree partial melting of a moderately depleted asthenospheric mantle source, with a negligible involvement of the thinned continental crust. The studied alkaline basalts represent the only known evidence of a segment of the Triassic rift system associated with early Pangea breakup in central Sicily. The close similarity of the central Sicily Triassic alkali basalts with coeval basalts emplaced along former orogenic sutures across the peri-Mediterranean area suggests a common origin related, at least partly, to asthenospheric passive upwelling following the tectonic collapse of the Variscan Belt. These rocks provide new constraints on the spatial-temporal distribution, magma source evolution and geodynamic meaning of the widespread Permo-Triassic basic magmatism developed after the end of the Variscan Orogeny in southwestern Europe.

    This first region-wide study (N = 2,818) aims to estimate prevalence of HIV-related risks (sexual behavior, HIV disclosure, number of sex partners, violence) and factors associated with these risks as well as evaluate a behavior change communications program targeted to PLHIV in 6 countries in Central America. After 2 years, the program achieved moderate coverage, with 21 % of the sample reporting exposure to interpersonal communications (IPC) and 52 % to mass media program components. The odds of condom use, HIV disclosure, and participation in a self-help group increased by 1.4-1.8 times with exposure to mass media. Exposure to IPC increased odds of condom use by 2.7 and participation in self-help groups by 4.4 times. In addition, being in HIV care or taking ART was associated with condom use and HIV-status disclosure. About 30 % experienced physical or sexual violence, and those who did were 4 times less likely to use condoms. Findings suggest that behavioral interventions for PLHIV can reduce HIV-transmission risks and increase access to care. PMID:25284460

    Full Text Available Fluvial deposits of the S. Maria di Ciciliano Formation crop out near Montecastrilli (Terni, in the southwestern branch of the Tiberino Basin.  Many specimens of plants ("mummified" woods, fruits and seeds, freshwater molluscs, ostracods, vertebrate bones and coprolites were collected at Torre Picchio. This small outcrop contains a fairly rich record of fruits and seeds, among which about 50 species were identified; the most frequent invariably belong to submerged, floating and emergent aquatic herbs, possibly because these were buried not far from their place of growth, thus representing the ancient local vegetation.  The fruits and seeds of woody plants, including several exotic elements, were transported from neighbouring areas and indicate a paleoclimate similar to the present day, though slightly wetter.  Among molluscs, three distinct assemblages were found, indicating fluvial, swampy and lacustrine environment, respectively.  They contain taxa of biochronological interest, most of them typical of Early Pleistocene deposits (late Villafranchian, but making their first appearance in the Late Pliocene (Middle Villafranchian. One species, Margarifera (Pseudunio auricularia, represents the oldest record everywhere, since it was known, so far, only from the Middle Pleistocene upwards.  As palaeoenvironmental indicators, the ostracods complete the information given by molluscs.  Vetrebrates are represented by large and small mammals, rare birds, reptiles, amphibians and some fishes.  A great number of coprolites was collected as well.  The mammal assemblage shows affinities with the Costa S. Giacomo and Olivola F. U. (Middle and Late Villafranchian, Late Pliocene. Mimomys medasensis, an Iberoccitane element, is signaled for the first time in Italy.  From the geological point of view, the S. Maria di Ciciliano Fm. is interfingering with the marine Chiani-Tevere Fm., which is mostly Santernian in age and lies unconformably on the Middle

    Sulfide oxidation forms a critical step in the global sulfur cycle, although this process is notoriously difficult to constrain due to the multiple pathways and highly reactive intermediates involved. Multiple sulfur isotopes (δ34S and Δ33S) can provide a powerful tool for unravelling sulfur cycling processes in modern (and ancient) environments, although they have had limited application to systems with well-resolved oxidative S cycling. In this study, we report the major (δ34S) and minor (Δ33S) isotope values of sulfur compounds in streams and sediments from the sulfidic Frasassi cave system, Marche Region, Italy. These microaerophilic cave streams host prominent white biofilms dominated by chemolithotrophic organisms that oxidize sulfide to S0, allowing us to estimate S isotope fractionations associated with in situ sulfide oxidation and to evaluate any resulting isotope biosignatures. Our results demonstrate that chemolithotrophic sulfide oxidation produces 34S enrichments in the S0 products that are larger than those previously measured in laboratory experiments, with 34εS0-H2S of up to 8‰ calculated. These small reverse isotope effects are similar to those produced during phototrophic sulfide oxidation (⩽7‰), but distinct from the small normal isotope effects previously calculated for abiotic oxidation of sulfide with O2 (∼-5‰). An inverse correlation between the magnitude of 34εS0-H2S effects and sulfide availability, along with substantial differences in Δ33S, both support complex sulfide oxidation pathways and intracellular recycling of S intermediates by organisms inhabiting the biofilms. At the ecosystem level, we calculate fractionations of less than 40‰ between sulfide and sulfate in the water column and in the sediments. These fractionations are smaller than those typically calculated for systems dominated by sulfate reduction (>50‰), and contrast with the commonly held assumption that oxidative recycling of sulfide generally

    Full Text Available The awareness of the central government and other supportive agencies in Italy as to the need for research to be accomplished in music and music history in that country is determined by first stating what that support has been for such research in the 1990s, together with its accessibility to groups and/or individuals working in that field, and then reporting how such aid has been reduced in the more recent times of financial crises. In order to assess Italy’s position not in isolation but more realistically by considering it within a broader geographical frame, the same investigation has been accomplished for a group of other culturally developed countries in Europe which offer sufficient areas of comparison: Spain, France, England, Germany. Sadly, Italy does not come off well. Perhaps surprisingly but still sadly this is shown not to be due to the present financial crises but to a long-standing absence of respect for the entire musical history of the country and for the need that it be known and understood thoroughly. In short, the government in Italy seems not to have been sufficiently aware of its responsibility to acknowledge and preserve its musical patrimony by adequately supporting research which aims at uncovering the country’s rich past, understanding it, and thereby making it available to professional performing musicians and, through them, also to the people of Italy and the rest of the world.

    The aim of this study was to examine whether incidence of malignant neoplasms of the central nervous system from 1993 to 2010 has increased among young people in Japan, and whether the increase could be explained by increase in mobile phone use. Joinpoint regression analysis of incidence data was performed. Subsequently, the expected incidence rate was calculated assuming that the relative risk was 1.4 for those who used mobile phones more than 1640 h cumulatively. Annual percent change was 3.9% (95% confidence interval [CI], 1.6-6.3) for men in their 20s from 1993 to 2010, 12.3% (95% CI, 3.3-22.1) for women in their 20s from 2002 to 2010, 2.7% (95% CI, 1.3-4.1) for men in their 30s from 1993 to 2010, and 3.0% (95% CI, 1.4-4.7) for women in their 30s from 1993 to 2010. Change in incidence rates from 1993 to 2010 was 0.92 per 100,000 people for men in their 20s, 0.83 for women in their 20s, 0.89 for men in their 30s, and 0.74 for women in their 30s. Change in expected incidence rates from 1993 to 2010 was 0.08 per 100,000 people for men in their 20s, 0.03 for women in their 20s, 0.15 for men in their 30s, and 0.05 for women in their 30s. Patterns in sex-, age-, and period-specific incidence increases are inconsistent with sex-, age-, and period-specific prevalence trends, suggesting the overall incidence increase cannot be explained by heavy mobile phone use.

    This paper reports that the thermal springs discharging in the Siena-Radicofani basin and the deep fluids within the geothermal systems of Piancastagnaio (Mt Amiata), Torre Alfina and Latera (Vulsini Mts) have a common origin. The chemical composition and evolution towards the low enthalpy of the springs as compared to the high enthalpy of the geothermal fluids are affected by both the structural setting of the region and the deep hydraulic conditions. Recharge of both the shallow thermal aquifer and the deep geothermal systems takes place in the outcrop areas of Mesozoic carbonate rocks, which constitute the main potential geothermal reservoir in central Italy. The waters of meteoric origin are heated at depth, as a consequence of anomalous heat flow in the region; these waters acquire a CO[sub 2]-rich rising gas phase, equilibrate with the reservoir rocks and, finally, assume their Ca--HCO[sub 3]--SO[sub 4] composition. If these waters discharge rapidly from the border fault systems of the Siena-Radicofani basin they maintain their original composition. If, instead, they emerge from the inner faults of the graben, their temperature and dissolved solids increase so that they become Na--Cl with a high content of NH[sub 4], and H[sub 3]BO[sub 3].

    The extensional Neogene Albegna Basin (Southern Tuscany, Italy) includes several thermogene travertine units dating from the Miocene to Holocene time. During the late Miocene (Messinian), a continental fault-controlled basin (of nearly 500-km2 width) was filled by precipitated travertine and detrital terrigenous strata, characterized by a wedge-shaped geometry that thinned northward, with a maximum thickness of nearly 70 m. This mixed travertine-terrigenous succession was investigated in terms of lithofacies types, depositional environment and architecture and the variety of precipitated travertine fabrics. Deposited as beds with thickness ranging from centimetres to a few decimetres, carbonates include nine travertine facies types: F1) clotted peloidal micrite and microsparite boundstone, F2) raft rudstone/floatstone, F3) sub-rounded radial coated grain grainstone, F4) coated gas bubble boundstone, F5) crystalline dendrite cementstone, F6) laminated boundstone, F7) coated reed boundstone and rudstone, F8) peloidal skeletal grainstone and F9) calci-mudstone and microsparstone. Beds of terrigenous deposits with thickness varying from a decimetre to > 10 m include five lithofacies: F10) breccia, F11) conglomerate, F12) massive sandstone, F13) laminated sandstone and F14) claystone. The succession recorded the following three phases of evolution of the depositional setting: 1) At the base, a northward-thinning thermogene travertine terraced slope (Phase I, travertine slope lithofacies association, F1-F6) developed close to the extensional fault system, placed southward with respect to the travertine deposition. 2) In Phase II, the accumulation of travertines was interrupted by the deposition of colluvial fan deposits with a thickness of several metres (colluvial fan lithofacies association, F10 and F12), which consisted of massive breccias, adjacent to the alluvial plain lithofacies association (F11-F14) including massive claystone and sandstone and channelized

    Italy is the sixth largest country in Europe and has the second highest average life expectancy, reaching 79.4 years for men and 84.5 years for women in 2011. There are marked regional differences for both men and women in most health indicators, reflecting the economic and social imbalance between the north and south of the country. The main diseases affecting the population are circulatory diseases, malignant tumours and respiratory diseases. Italy's health care system is a regionally based national health service that provides universal coverage largely free of charge at the point of delivery. The main source of financing is national and regional taxes, supplemented by copayments for pharmaceuticals and outpatient care. In 2012, total health expenditure accounted for 9.2 percent of GDP (slightly below the EU average of 9.6 percent). Public sources made up 78.2 percent of total health care spending. While the central government provides a stewardship role, setting the fundamental principles and goals of the health system and determining the core benefit package of health services available to all citizens, the regions are responsible for organizing and delivering primary, secondary and tertiary health care services as well as preventive and health promotion services. Faced with the current economic constraints of having to contain or even reduce health expenditure, the largest challenge facing the health system is to achieve budgetary goals without reducing the provision of health services to patients. This is related to the other key challenge of ensuring equity across regions, where gaps in service provision and health system performance persist. Other issues include ensuring the quality of professionals managing facilities, promoting group practice and other integrated care organizational models in primary care, and ensuring that the concentration of organizational control by regions of health-care providers does not stifle innovation.

    The purpose of this study is to gain a better understanding on the tectonic structures featuring in a crucial sector of central Mediterranean area, including the Aeolian Islands, southern Calabria, and northeastern Sicily, where the convergence between Eurasian and African Plates has given rise to a complicated collisional/subduction complex. A high-quality data set of about 3000 earthquakes has been exploited for local earthquake tomography and focal mechanisms computation together with available source mechanisms from published catalogues. The results depict new details of a network of faults which enables the concurrent existence of adjacent compressional and extensional domains. In particular, tomographic images, seismic events distribution, and focal mechanisms pinpoint the geometry and activity of a lithospheric-scale tear faults system which, with a NW-SE trend through Sicily and the Tyrrhenian and Ionian Seas, represents the southern edge of the Ionian subduction trench zone. At crustal depth, this tearing is well highlighted by a rotation of the maximum horizontal stress, moving across the area from west toward east. In addition, the shallow normal fault regime, characterizing the southern Calabria and northeastern Sicily mainland, south of the NW-SE lineament, changes in the deeper part of the crust. Indeed, a NE-SW earthquake distribution, gently dipping NW, and inverse fault solutions indicate a still active contractional deformation in eastern Sicily, caused by the Africa-Eurasia convergence and well framed with the current compressive regime along the southern Tyrrhenian zone and at the front of the Sicilian Chain-Foreland.

    The Piano di Pezza fault is the central section of the 35 km long L'Aquila-Celano active normal fault-system in the central Apennines of Italy. Although palaeoseismic data document high Holocene vertical slip rates (˜1 mm yr-1) and a remarkable seismogenic potential of this fault, its subsurface setting and Pleistocene cumulative displacement are still poorly known. We investigated for the first time the shallow subsurface of a key section of the main Piano di Pezza fault splay by means of high-resolution seismic and electrical resistivity tomography coupled with time-domain electromagnetic soundings (TDEM). Our surveys cross a ˜5-m-high fault scarp that was generated by repeated surface-rupturing earthquakes displacing Holocene alluvial fans. We provide 2-D Vp and resistivity images, which show significant details of the fault structure and the geometry of the shallow basin infill material down to 50 m depth. Our data indicate that the upper fault termination has a sub-vertical attitude, in agreement with palaeoseismological trench evidence, whereas it dips ˜50° to the southwest in the deeper part. We recognize some low-velocity/low-resistivity regions in the fault hangingwall that we relate to packages of colluvial wedges derived from scarp degradation, which may represent the record of some Holocene palaeo-earthquakes. We estimate a ˜13-15 m throw of this fault splay since the end of the Last Glacial Maximum (˜18 ka), leading to a 0.7-0.8 mm yr-1 throw rate that is quite in accordance with previous palaeoseismic estimation of Holocene vertical slip rates. The 1-D resistivity models from TDEM soundings collected along the trace of the electrical profile significantly match with 2-D resistivity images. Moreover, they indicate that in the fault hangingwall, ˜200 m away from the surface fault trace, the pre-Quaternary carbonate basement is at ˜90-100 m depth. We therefore provide a minimal ˜150-160 m estimate of the cumulative throw of the Piano di Pezza

    Post-Traumatic Stress Disorder (PTSD) is a chronic anxiety disorder. The continued efforts to control the distressing memories by traumatized individuals, together with the reduction of responsiveness to the outside world, are called Emotional Numbing (EN). The EN is one of the central symptoms in PTSD and it plays an integral role not only in the development and maintenance of post-traumatic symptomatology, but also in the disability of emotional regulation. This disorder shows an abnormal response of cortical and limbic regions which are normally involved in understanding emotions since the very earliest stages of the development of processing ability. Patients with PTSD exhibit exaggerated brain responses to emotionally negative stimuli. Identifying the neural correlates of emotion regulation in these subjects is important for elucidating the neural circuitry involved in emotional and empathic dysfunction. We showed that PTSD patients, all survivors of the L'Aquila 2009 earthquake, have a higher sensitivity to negative emotion and lower empathy levels. These emotional and empathic deficits are accompanied by neural brain functional correlates. Indeed PTSD subjects exhibit functional abnormalities in brain regions that are involved in stress regulation and emotional responses. The reduced activation of the frontal areas and a stronger activation of the limbic areas when responding to emotional stimuli could lead the subjects to enact coping strategies aimed at protecting themselves from the re-experience of pain related to traumatic events. This would result in a dysfunctional hyperactivation of subcortical areas, which may cause emotional distress and, consequently, impaired social relationships often reported by PTSD patients.

  13. Estimation of the geothermal potential of the Caldara di Manziana site in the Mts Sabatini Volcanic District (Central Italy) by integrating geochemical data and 3D-GIS modelling.

    High-enthalpy geothermal fields of Central Italy are hosted in deeply fractured carbonate reservoirs occurring in thermally anomalous and seismically active zones. However, the Mts. Sabatini volcanic district, located north of Rome, has an interesting deep temperatures (T), but it is characterized by low to very low seismicity and permeability in the reservoir rocks (mostly because of hydrothermal self-sealing processes). Low PCO2 facilitates the complete sealing of the reservoir fractures, preventing hot fluids rising and, determining a low CO2 flux at the surface. Conversely, high CO2 flux generally reflects a high pressure of CO2, suggesting that an active geothermal reservoir is present at depth. In Mts. Sabatini district, the Caldara of Manziana (CM) is the only zone characterized by a very high CO2 flux (188 tons/day) from a surface of 0.15 km2) considering both the diffuse and viscous CO2 emission. This suggests the likely presence of an actively degassing geothermal reservoir at depth. Emitted gas is dominated by CO2 (>97 vol.%). Triangular irregular networks (TINs) have been used to represent the morphology of the bottom of the surficial volcanic deposits, the thickness of the impervious formation and the top of the geothermal reservoir. The TINs, integrated by T-gradient and deep well data, allowed to estimate the depth and the temperature of the top of the geothermal reservoir, respectively to ~-1000 m from the surface and to ~130°C. These estimations are fairly in agreement with those obtained by gas chemistry (818lake is the most thermally anomalous zone of the area. Geothermometers and the GIS model indicated a temperature range between 120 and 150°C, confirming the presence of a medium-enthalpy geothermal resource in the Mts. Sabatini, but only at CM the low depth of the geothermal reservoir (~-1000m) makes this resource economically attractive.

  14. Determination of 222Rn in water by absorption in polydimethylsiloxane mixed with activated carbon and gamma-ray spectrometry: An example application in the radon budget of Paterno submerged sinkhole (Central Italy)

    International Nuclear Information System (INIS)

    Highlights: ► Polydimethylsiloxane and Activated Carbon were used as passive gas accumulator. ► Water-impermeable properties of PDMS combine with adsorptive properties of AC. ► PDMS–AC accumulators can be used to study 222Rn in water. ► Measured 222Rn specific activity in PDMS–AC matches the theoretical results. ► We used PDMS–AC in the radon budget of a submerged sinkhole. - Abstract: Passive gas accumulators made of polydimethylsiloxane (PDMS) mixed with activated C (AC) were studied to measure their efficiency for sampling Rn in water. In this composite the water-impermeable properties of PDMS act synergistically with adsorptive properties of AC, even when the accumulators are immersed in water for many days. A series of tests where cylindrical shaped PDMS–AC disks were exposed to different 222Rn-enriched waters showed that measured 222Rn specific activity matches the theoretical results coming from the equation that describes the process of internal diffusion integrated with the Rn decay term. The linear relationship between 222Rn in water and the accumulation process in PDMS–AC, the influence of temperature and the different sensitivity of the composite and its components were also studied and discussed. The high Rn volumetric enrichment factor in PDMS–AC disks respect to water resulted in about 206: 1, so lowering detection limits for 222Rn in water to 20 Bq m−3 when the total activity of Rn progeny in disks is measured by high resolution gamma-ray spectrometry. The use of PDMS–AC accumulators was tested at the Paterno submerged sinkhole, in central Italy. This study allowed the production of a detailed synchronous vertical profile of the Rn content in the middle of the lake and to define the Rn balance by assessing the discharge rate of submerged springs and the average residence time of the lake water

    Built environment is an important social determinant of health, but nowadays local health authorities (LHAs) have lost their competences in the issuing of building permits, especially since a new legislation introduced the possibility of personal declaration of conformity. They are also usually excluded from the urban planning process. At the same time, in recent years construction of buildings has been developed with insufficient regard to environmental health requirements, proper exposure to sunlight and winds, comfort, building materials, consumption of resources, and waste production. To deal with these issues, an interdepartmental working group was set up under the direction of the Department of Prevention of the LHA of Empoli (Tuscany Region, Central Italy), with members of the Regional Environmental Protection Agency, along with experts of the 15 Municipalities included in the LHA territory and members of other local institutions. The objective of the Working Group was to define and propose as mandatory a set of rules for local governments aimed at regulating construction activities according to criteria of environmental sustainability, eco-efficiency, comfort, and healthiness of living areas, at the same time encouraging the responsible use of natural resources, the reduction of energy consumption and the use of renewable energy sources in order to place environmental safety and health at the heart of all building activities. Experts of six Municipalities joined the working group and the regulation framework was adopted (and made legally binding) in 8 out of 15 Municipalities, with an almost complete overlap with participation in the working group. The active participation of experts, whose work consists in examining municipal building, permits, and declarations, has therefore marked the difference in the transition from theory to practice. The level of know-how attained by the participants and their motivation and enthusiasm have been so relevant in the

    The Italian national hydro-meteorological early warning system is composed by 21 regional offices (Functional Centres, CF). Umbria Region (central Italy) CF provides early warning for floods and landslides, real-time monitoring and decision support systems (DSS) for the Civil Defence Authorities when significant events occur. The alert system is based on hydrometric and rainfall thresholds with detailed procedures for the management of critical events in which different roles of authorities and institutions involved are defined. The real-time flood forecasting system is based also on different hydrological and hydraulic forecasting models. Among these, the MISDc rainfall-runoff model ("Modello Idrologico SemiDistribuito in continuo"; Brocca et al., 2011) and the flood routing model named STAFOM-RCM (STAge Forecasting Model-Rating Curve Model; Barbetta et al., 2014) are continuously operative in real-time providing discharge and stage forecasts, respectively, with lead-times up to 24 hours (when quantitative precipitation forecasts are used) in several gauged river sections in the Upper-Middle Tiber River basin. Models results are published in real-time in the open source CF web platform: www.cfumbria.it. MISDc provides discharge and soil moisture forecasts for different sub-basins while STAFOM-RCM provides stage forecasts at hydrometric sections. Moreover, through STAFOM-RCM the uncertainty of the forecast stage hydrograph is provided in terms of 95% Confidence Interval (CI) assessed by analyzing the statistical properties of model output in terms of lateral. In the period 10th-12th November 2013, a severe flood event occurred in Umbria mainly affecting the north-eastern area and causing significant economic damages, but fortunately no casualties. The territory was interested by intense and persistent rainfall; the hydro-meteorological monitoring network recorded locally rainfall depth over 400 mm in 72 hours. In the most affected area, the recorded rainfall depths

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

    Nearly all areas of business--not just sales and human resources--call for interpersonal savvy. Relational know-how comprises a greater variety of aptitudes than many executives think. Some people can "talk a dog off a meat truck," as the saying goes. Others are great at resolving interpersonal conflicts. Some have a knack for translating high-level concepts for the masses. And others thrive when they're managing a team. Since people do their best work when it most closely matches their interests, the authors contend, managers can increase productivity by taking into account employees' relational interests and skills when making personnel choices and project assignments. After analyzing psychological tests of more than 7,000 business professionals, the authors have identified four dimensions of relational work: influence, interpersonal facilitation, relational creativity, and team leadership. This article explains each one and offers practical advice to managers--how to build a well-balanced team, for instance, and how to gauge the relational skills of potential employees during interviews. To determine whether a job candidate excels in, say, relational creativity, ask her to describe her favorite advertising campaign, slogan, or image and tell you why she finds it to be so effective. Understanding these four dimensions will help you get optimal performance from your employees, appropriately reward their work, and assist them in setting career goals. It will also help you make better choices when it comes to your own career development. To get started, try the authors' free online assessment tool, which will measure both your orientation toward relational work in general and your interest level in each of its four dimensions.

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: Decommissioning of the NPP is generally viewed in a negative framework. On the contrary, it is an activity which aims is said to obtain the final removal of the risk factors from the environment. It is the last step of the production cycle, whose importance is underlined by the Regulation recently issued for the correct management of resources in the territory. Decommissioning NPP involves the final arrangements of the radioactive wastes, produced either during the past operation period or resulting from the dismantling operation. All the radioactive wastes must be conditioned and maintained in safe conditions. Radioactive waste management is no longer a problem for those countries that decided to face it, that is the majority of the industrialised countries. Correct technological solutions exist, due exist, respectful of the environment, of the people, of the ethical principles. The centrality of the problem is also decreed by the fact that sometimes now, the European Commission has been working on the issue of the directive on waste management, an effort which Italy has strongly supported, also during the Presidency period. Decommissioning on NPP is moreover an activity that implies advanced technological solutions, multilateral overlapping programs, working of style situations. Not many countries have completed yet (the) decommissioning of their plants: such activity should therefore be seen as an opportunity for the growth and the assertion of the Italian industry, also in view of the potential new market and the alliance with European industries. Of the 530 nuclear reactors present in world today, approximately 100 are undergoing decommissioning. In the next 2 years another 100 will reach the end of their operative life. Probably after the necessary system improvement many of them will continue to work, but it is clear that the international market of the decommissioning will continue to grow in the next years. Italy can play an important role in

    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.

    At the close of 2007, about 4 million foreign people were living in Italy (20 years ago, the same could be said of only a few thousand), the majority of whom were employed in low paying of jobs refused by Italians. As the housing situation in Italy since 1975 has been predominantly characterized by homeownership, the purchase of a house for both Italian and foreign families has become a matter of both survival and “citizenship”. In this paper, we use an exploratory approach to describe the ho...

  1. Public participation in the decision making process in the nuclear field in Italy

    International Nuclear Information System (INIS)

    In Italy, the decision making process to localize, construct and operate electronuclear power stations have been restructured and such a process today must follow the rules enacted by three laws: the Act of 2 August 1975 about the procedures for choosing the site; the Act of 8 July 1986 about the rules for the environmental impact evaluation, the so-called VIA which in italian means GO; the Act of 10 August 1988 which states that the construction of nuclear waste processing plants and nuclear waste storage plants must pass the Environment Impact Evaluation. In Italy there are three levels of Local government,'Regioni', 'Provincie' and 'Comuni', that are free to compete among themselves and with the Central government, so that it is very sticky to implement any decision. The Public Inquiry is a strongly innovative instrument. The Environmental Impact Evaluation procedure guarantees the transparency of the decision making process and supplies a real communication channel between the public opinion and the authorities. In the Public Inquiry any association, organization, union or group of people have the right to verify any part of the project under the Environmental Impact Evaluation and to express their consideration and observation on the subject

    2003-01-01

    The development of Occupational Epidemiology in Italy is closely correlated with the political and social awareness of the needs of preventive strategies in the workplace. In the late '60s the Trade Unions supported a model of intervention based on the involvement of the so-called "Homogeneous group of workers" in the validation of the preventive measures taken on the workplace. In spite of the shortcomings of the model, it was extremely effective resulting in enhanced perception of the priority of preventive strategies and in the formation within the National Health Service of the Occupational Health Services. In Italy over the period 1973-2002 there has been an impressive trend of research in field of occupational epidemiology (a search on Medline shows an increasing trend over the years and, in terms of international comparison, higher figures than in Germany, France and Spain). Occupational Epidemiology is now present in the activities of the local Occupational Health Services and in the teaching activities of the Medical Schools throughout the country. PMID:14582235

    Full Text Available Background: Actually there is no survey on the oral health of elderly in Lazio region or in Rome. Study aims to assess the dental and oral health status and treatments needs of the elderly population in Rome in order to assess need for care. Materials and Methods: 316 non institutionalized patients all living in Rome underwent a complete oral and dental examination following the WHO's criteria. Statistical analysis was performed using SPSS Inc, ver. 13.0, Chicago, IL, USA. A p-value of less than 0.05 was considered significant. Results: The prevalence of edentulousness was 4.4%. Missing teeth were 3346 (37,81%. After grouping patients by age (65-69, 70-74, 75-79, 80 and over we found that only in the first group (65-69 women had a lower number (p<0.001 of missing teeth than men: women 359 (23,31%, men 393 (35,08%. Mean number of remaining teeth per subject was 17,41. Both genders in the mandible presented a greater number of teeth present (9.02 on average than the maxilla (8.27 on average; p=0.002. Decayed, Missing, Filled Teeth index (DMFT index was 14.65 (D:7,73%, M:81,57% and F:10,69%.. Regarding Community Periodontal Index (CPI 14,5% of the sextants resulted healthy, 4.9% had gingival bleeding on probing, 20.7% had dental calculus, 17.0% periodontal pockets 4-5mm deep, 1.4% pockets 6 or more mm deep and 41.5% of the sextants were excluded. Conclusions: The findings illustrated a promising oral and dental health status compared to other European countries. The status of oral health was significantly better in women than in men in the first age group 65-69, increase in age results in a worsening of all indices.

  6. 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

    Full Text Available In this paper the relationship between criminal victimization and people’s perception of safety is explored. At first sight, the connection between these phenomena seems to be obvious: victims of a crime are probably more unsafe than non victimized people. However, many studies have found that the relationship between fear and crime is more complex than expected. In the first part of the paper the mixed research results are discussed and some reasons of this heterogeneity are identified. In the second part an analysis is conducted on data from the Italian Survey on Citizens’ Safety (Indagine sulla sicurezza dei cittadini. The main findings indicate that victimization affects both feelings of safety in the streets and in one’s own home, but with different intensity. Theft and snatch victimization is associated with safety in the streets, whereas burglary victimization with the perception of safety in one’s own home. Multivariate binomial regression models show that in Italy previous victimization contributes to increase the probability of feeling unsafe both in the streets and in one’s own home, all else being equal.Le but de cet article est d'analyser la relation entre l'expérience de victimisation et le sentiment d'insécurité collective. Au premier regard, la relation entre ces deux phénomènes peut sembler évidente: le sentiment d'insécurité est peut-être plus fort chez les victimes de crime que chez ceux qui n'ont jamais été frappés par le crime. Toutefois, beaucoup d'études ont montré que la relation entre l'insécurité et le crime est plus complexe qu'on ne l'avait prévu. Dans la première partie de cet article, nous discutons les résultats contradictoires des études mentionnées plus haut et identifions quelques-un des motifs de cette hétérogénéité. Dans la deuxième partie, nous effectuons une analyse sur les données de l'enquête italienne sur la sécurité des citoyens (Indagine sulla sicurezza dei

    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.

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

    2008-09-01

    Full Text Available A major gastroenteritis outbreak was reported in a vacation resort in Central Italy in 2003. A total of 183 cases were identified. The case-control study identified a statistically significant correlation between the disease and sea bathing, use of sanitary facilities in bungalows and of common showers. Stool samples taken from people affected were found positive for Norovirus (68%, 13 of 19 samples, Rotavirus (38%, 1 of 14 samples and Campylobacter (7%, 3 of 8 samples. Environmental investigations revealed serious faecal contamination of the groundwater and the presence of Norovirus in the seawater near the resort. The mixing of groundwater and seawater with the non-drinking water system - which was also found to be connected to the drinking water system - had a primary role in the onset and spread of infection within the village. The complete absence of any gastroenteritis epidemics among the site guests since 2006 demonstrates the effectiveness of the environmental corrective measures taken.

    2000-01-01

    Graz gestalt psychology was introduced into Italy after World War I with Vittorio Benussi's emigration to Padua. His earliest adherent, Cesare Musatti, defended Graz theory, but after Benussi's premature death became an adherent of the Berlin gestalt psychology of Wertheimer-Köhler-Koffka. He trained his two most important students, Fabio Metelli and Gaetano Kanizsa, in orthodox Berlin theory. They established rigid "schools" in Padua and Trieste. The structure of Italian academics allowed for such strict orthodoxy, quite unlike the situation in America, where scientific objectivity mitigated against schools. In the 1960s, some of the students of Metelli and Kanizsa (above all Bozzi) initiated a realist movement-felt in Kanizsa's late work-that was quite independent of that of J. J. Gibson. Finally, more recently, Benussi and Graz theorizing have been embraced again, sentimentally, as a predecedent to Kanizsa-Bozzi. PMID:10653614

    2011-07-01

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

    Full Text Available INTRODUCTION: Prevalence of infection with HIV-1 non-B subtypes in Italy has been reported to raise, due to increased migration flows and travels. HIV-1 variants show different biological and immunological properties that impact on disease progression rate, response to antiretroviral therapy (ART and sensitivity of diagnostic tests with important implications for public health. Therefore, a constant surveillance of the dynamics of HIV variants in Italy should be a high public health priority. Organization of surveillance studies requires building up a platform constituted of a network of clinical centers, laboratories and institutional agencies, able to properly collect samples for the investigation of HIV subtypes heterogeneity and to provide a database with reliable demographic, clinical, immunological and virological data. AIM: We here report our experience in building up such a platform, co-ordinated by the National AIDS Center of the Istituto Superiore di Sanita, taking advantage of a pilot study aimed at evaluating HIV subtypes diversity in populations of HIV-infected migrant people in Italy. MATERIALS AND METHODS: Four hundred and thirty four HIV-infected migrants were enrolled in 9 Italian clinical centers located throughout the Italian territory. Standard Operating Procedures (SOPs for sample collection were provided by the National AIDS Center to each clinical center. In addition, clinical centers were required to fill up a case report form (crf for each patient, which included demographic, clinical, immunological and virological information. RESULTS: All centers properly collected and stored samples from each enrolled individual. Overall, the required information was correctly provided for more than 90% of the patients. However, some fields of the crf, particularly those including information on the last HIV-negative antibody test and presence of co-infections, were properly filled up in less than 80% of the enrolled migrants.

    Full Text Available The study examines the Slovenian-speaking minority in the northern Italian autonomous region of Friuli-Venezia Giulia. It explores the spatial fragmentation in the Slovenian settlement area in Italy and analyzes the socio-economic and demographic processes that exert influence on the minority. The work is based on the critical evaluation of the current status of research, of statistical data from the state censuses and results of own research on site. The Slovenian-language population in the entire region is currently estimated at about 46,000 people.

  4. An agreement for applied research in Italy

    CERN Multimedia

    2002-01-01

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

    Background Bovine besnoitiosis, caused by the apicomplexan Besnoitia besnoiti, is a chronic and debilitating disease considered as emerging in Europe. In Spain, Portugal and France it is endemic and foci of infection were recorded in Germany, Switzerland, Hungary, Greece and Italy. In Italy, cases of bovine besnoitiosis were registered both in imported and autochthonous cattle, and mostly in central regions; high seroprevalence was also revealed by an epidemiological survey performed in the s...

    We present new results for the microseismic activity in the Central Apennines recorded from a total of 81seismic stations. The large number of recording sites derives from the combination of temporary and permanent seismic networks operating in the study region. Between January 2009 and October 2013 we recorded 6923 earthquakes with local magnitudes ML ranging from 0.1 to 4.8. We located hypocentres by using a refined 1D crustal velocity model. The majority of the hypocenters are located beneath the axes of the Apenninic chain, while the seismic activity observed along the peri-Tyrrhenian margin is lower. The seismicity extends to a depth of 32 km; the hypocentral depth distribution exhibits a pronounced peak of seismic energy release in the depth range between 8 and 20 km. During the observation period we recorded two major seismic swarms and one seismic sequence in the Marsica-Sorano area in which we have had the largest detected magnitude (ML = 4.8). Fault plane solutions for a total of 600 earthquakes were derived from P-polarities. This new data set consists of a number of focal plane solutions that is about four times the data so far available for regional stress field study. The majority of the focal mechanisms show predominantly normal fault solutions. T-axis trends are oriented NE-SW confirming that the area is in extension. We also derived the azimuths of the principal stress axes by inverting the fault plane solutions and calculated the direction of the maximum horizontal stress, which is mainly sub-vertical oriented. The study region has been historically affected by many strong earthquakes, some of them very destructive. This work can give an important contribution to the seismic hazard assessment in an area densely populated as the city of Rome which is distant around 60 km from the main seismogenic structures of Central Apennine.

    A comparative food ethnobotanical study was carried out in twenty-one local communities in Italy, fourteen of which were located in Northern Italy, one in Central Italy, one in Sardinia, and four in Southern Italy. 549 informants were asked to name and describe food uses of wild botanicals they currently gather and consume. Data showed that gathering, processing and consuming wild food plants are still important activities in all the selected areas. A few botanicals were quoted and cited in multiple areas, demonstrating that there are ethnobotanical contact points among the various Italian regions (Asparagus acutifolius, Reichardia picroides, Cichorium intybus, Foeniculum vulgare, Sambucus nigra, Silene vulgaris, Taraxacum officinale, Urtica dioica, Sonchus and Valerianella spp.). One taxon (Borago officinalis) in particular was found to be among the most quoted taxa in both the Southern and the Northern Italian sites. However, when we took into account data regarding the fifteen most quoted taxa in each site and compared and statistically analysed these, we observed that there were a few differences in the gathering and consumption of wild food plants between Northern and Southern Italy. In the North, Rosaceae species prevailed, whereas in the South, taxa belonging to the Asteraceae, Brassicaceae, and Liliaceae s.l. families were most frequently cited. We proposed the hypothesis that these differences may be due to the likelihood that in Southern Italy the erosion of TK on wild vegetables is taking place more slowly, and also to the likelihood that Southern Italians' have a higher appreciation of wild vegetables that have a strong and bitter taste. A correspondence analysis confirmed that the differences in the frequencies of quotation of wild plants within the Northern and the Southern Italian sites could be ascribed only partially to ethnic/cultural issues.

  16. Nuclear power in Italy

    International Nuclear Information System (INIS)

    As is known to most of this audience in November of 1987 a referendum determined a rejection of nuclear power in Italy. The referendum may be taken into consideration here as a large scale experiment which offers points of interest to this conference and problems to be aware of, in approaching a severe confrontation with the public. To give a synopsis of the Italian perspective I will examine: first the public acceptance in the situation before Chernobyl, then the most disturbing and sensitive factors of Chernobyl's consequences; how the opposition to nuclear energy worked with the support of most media and the strong pressures of an anti-nuclear political party, the syllogism of the opponents and the arguments used, the causes of major weakness of the defenders and how a new perception of nuclear risk was generated in the public. I will come to the topic of utility acceptance by mentioning that ENEL, as the National Utility, in its role is bound to a policy of compliance with Government decisions. It is oriented today to performance of feasibility studies and development of requirements for the next generation of reactors in order to maintain an updated proposal for a future recovery of the nuclear option. I will then try to identify in general terms the factors determining the future acceptance of nuclear power. They will be determined in the interdisciplinary area of politics, media and public interactions with the utilities the uses of the technology are forced to follow, by political constraints, two main directives: working only in new projects to achieve, if possible, new safety goals

    2008-12-01

    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.

    threshold of absolute poverty and may lead to social exclusion, a condition with a heavy impact on health, which in Italy includes marginal groups of the native population and broader classes of immigrants (chapter 1.3, Section I). Finally, there is recent and consistent evidence on the existence of a "contextual" effect on health, as opposed to the "compositional" effect given solely by the aggregation of individual processes. According to this hypothesis, characteristics of the infrastructure, and the physical and socioeconomic environment of an area would have an impact on individual health independent from the cultural and economic resources personally available to people living in that area (chapter 1.8, Section I). With respect to the health care system, various studies are in agreement in demonstrating that poor and less educated people have inadequate access both to primary prevention and early diagnosis (chapter 2.1, Section I), and to early and appropriate care (chapter 2.2, Section I). They also experience higher rates of hospitalization, particularly in emergencies and with advanced levels of severity. PMID:15537046

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

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

    Directory of Open Access Journals (Sweden)

    Anna Garriga

    2015-12-01

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

    Neonatal hearing loss is the most frequent sensorial congenital defect in newborns. No data are available on worldwide prevalence of congenital deafness. World Health Organization (WHO) data indicate 1-4 cases per 1000 individuals, with a considerable increase in developing countries. A prevalence exceeding 1 per 1000 however, indicates a serious public health problem calling for urgent attention. Aim of the study was the evaluate the prevalence of prelingual deafness in the Italian population and determine the socio-demographic characteristics of the condition. Data were provided by the National Institute of Social Insurance (INPS) and the Italian Central Statistics Institute (ISTAT) and were collected in 18 out of the 20 Italian regions (98.2% of total population). All subjects recognized as deaf-mute by a special medical committee were included. According to law No. 509/1988, they had to present a mean bilateral sensorineural-hearing impairment, detected in neonatal age, which caused the damage in speech development and equal to 60 dB or more for 500-, 1000- and 2000-Hz frequency tones in the better ear. Prevalence rates were calculated according to region and age bracket using updated population data from census 2001. Statistical analyses were performed using the SPSS statistical software package. A total of 40,887 cases of prelingual profound sensorineural hearing loss > or =60 dB were detected in Italy in 2003, for a total prevalence rate of 0.72 per 1000. The hearing impairment prevalence differs according to sex. The overall prevalence is 0.78 per 1000 for males and 0.69 per 1000 for females (p 64 age groups reached 1.27 and 1.15, respectively. This phenomenon may have been due, in part, to the epidemic incidence of maternal rubella which occurred in the 40's and 50's (in Italy, the rubella vaccination was only recommended starting from 1972), and, in part, to the habit of contracting consanguineous marriages.

    2013-09-01

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

  11. Surfactant damages on coastal vegetation in southern Italy

    Directory of Open Access Journals (Sweden)

    2005-01-01

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

    2016-03-01

    Various changes in the sociopolitical milieu of Italy led to the increasing tolerance of the study of cadavers in the late Middle Ages. The efforts of Mondino de Liuzzi (1276-1326) and Guido da Vigevano (1280-1349) led to an explosion of cadaver-centric studies in centers such as Bologna, Florence, and Padua during the Renaissance period. Legendary scientists from this era, including Leonardo Da Vinci, Andreas Vesalius, Bartolomeo Eustachio, and Costanzo Varolio, furthered the study of neuroanatomy. The various texts produced during this period not only helped increase the understanding of neuroanatomy and neurophysiology but also led to the formalization of medical education. With increased understanding came new techniques to address various neurosurgical problems from skull fractures to severed peripheral nerves. The present study aims to review the major developments in Italy during the vibrant Renaissance period that led to major progress in the field of neurosurgery. PMID:26585723

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

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

    2014-05-01

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

    2009-04-01

    In this work we analyze data from permanent and non-permanent GPS stations collected between 1998 and 2006 on a dense geodetic network covering a large area of the Hyblean Plateau (southern Italy). This is a seismogenetic area, where strong earthquakes destroyed many cities and killed thousands of people in the past. The analysis of geodetic velocities referring to an Eurasian and an African reference frames, reveals the occurrence of active shortening in the northern sector of the plateau along the boundary defined by the Gela-Catania Foredeep, coupled with an active lengthening in the central sector of the plateau itself. Starting from the estimated velocity at each station, the horizontal strain-rate field of the Hyblean Plateau was calculated. The strain rate pattern clearly defines an area of a prevailing N-S compression along the northern rim of the Hyblean Plateau. Furthermore the central sector of the plateau is affected by a NNW-SSE and NE-SW extensional strain rate pattern. A comparison with seismological and structural data, available for the studied area, allows improving the knowledge of the tectonic processes in the Hyblean Plateau and their implications for seismic hazard.

    In the past 5 years the Italian monitoring system, managed by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) has been strongly improved, thanks to support from the National Dept. of Civil Protection (DPC). Basic goals of the network are the rapid evaluation of earthquake parameters and the acquisition of high quality data for seismological research on earthquake source and deep structure. Particular emphasis has been given to real- time data transmission, network robustness and redundancy, multisensor remote stations. Presently, data from more than 250 stations are received in real-time at the INGV acquisition system in Rome, mostly through satellite links (about 100) and terrestrial digital lines (about 100), while other data are received through radio links and Internet. Our stations are equipped with either commercial (mostly Nanometrics) or INGV- produced digitizers (GAIA2). MedNet data in Italy and EuroMed regions are also used for real time monitoring. MedNet data are shared in real-time with ORFEUS and IRIS, while data from the National Seismic network are presently distributed for triggered events a few minutes after an earthquake. Data latencies are mostly in the range 0-10 s, with the upper limit (constrained by satellite channel sharing) presently being reduced down to 3 s. Most of the stations are equipped with either Trillium 40s, 120s or 240s, or STS2 seismometers, coupled with Episensor accelerometers. In about 100 sites, continuous GPS's send stream data in real time to the INGV centres, at 1s or 30s sampling rate. Data from GPS receivers are available at http:ring.gm.ingv.it for a subset of the network. A few dense dial-up local networks in central Italy contribute to the monitoring system. Beside a centralized acquisition in Rome, data from wide regions covered by the network are transmitted in real time to other INGV centres (Grottaminarda, Catania) to guarantee redundancy and disaster recovery. In volcanic areas, such as Etna and

  5. Spent fuel management strategy in Italy

    International Nuclear Information System (INIS)

    As a consequence of a national referendum in 1987, the Italian Government decided to close definitively all operating NPPs in Italy. Plans for decommissioning of the NPPs and disposal of the spent fuel had to be reviewed and the strategies revisited. The majority of spent fuel was by large that generated by ENEL NPPs, which decided to proceed with the interim storage of the spent fuel (< 250 t/HM) not covered by reprocessing contracts. ENEL finally decided to follow the strategy of interim dry storage in metallic casks on the plant sites, which could ensure a timely removal of the fuel from the to be decommissioned plant pools, in compliance with decommissioning programmes, independently from the availability of a centralized interim storage site. Therefore, the casks will be stored provisionally on Trino and Caorso sites, then they will be transported to the centralized interim facility, as soon as it will be made available by the Government. Current planning foresees that the Trino spent fuel pool shall be emptied by the end of 2002 and the Caorso pool at the end of 2004. An international bidding phase is currently underway. A smaller residual quantity of spent fuel is also currently owned in Italy by ENEA, the National Agency, responsible also for the nuclear research. Also ENEA has a programme of storing its spent fuel in dry metallic casks with the aim of transporting them to the national storage site as soon as it will be available. ENEL's Technical Specifications for the casks are stringent, but in line with other European installations of the same type, taking into account also recent US NRC regulatory documents, in particular on protection against aircraft crash. Design margins to accommodate site characteristics not currently identified (the European Utility Requirements reference site parameters have been used), have been introduced. Some important issues are identified, such as: definition and identification of failed fuel elements and/or pins, specific

    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.

  15. Energy and environment in Italy

    International Nuclear Information System (INIS)

    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

    The increasing volume and complexities of migratory flow has led to a range of problems such as human rights issues, public health, disease and border control, and also the regulatory processes. As result of war or internal conflicts missing person cases and management have to be regarded as a worldwide issue. On the other hand, even in peace, the issue of a missing person is still relevant. In 2007 the Italian Ministry of Interior nominated an extraordinary commissar in order to analyse and assess the total number of unidentified recovered bodies and verify the extent of the phenomena of missing persons, reported as 24,912 people in Italy (updated 31 December 2011). Of these 15,632 persons are of foreigner nationalities and are still missing. The census of the unidentified bodies revealed a total of 832 cases recovered in Italy since the year 1974. These bodies/human remains received a regular autopsy and were buried as 'corpse without name". In Italy judicial autopsy is performed to establish cause of death and identity, but odontology and dental radiology is rarely employed in identification cases. Nevertheless, odontologists can substantiate the identification through the 'biological profile' providing further information that can narrow the search to a smaller number of missing individuals even when no ante mortem dental data are available. The forensic dental community should put greater emphasis on the role of the forensic odontology as a tool for humanitarian action of unidentified individuals and best practise in human identification.

Vitamin D deficiency (25OHD level <20 ng/mL was very frequent among RA patients; its prevalence was 60%, 52% and 38% in southern, central and northern Italy, respectively. Mean disease activity and disability scores were worse in southern regions of Italy. These scores were inversely related to 25OHD levels and this correlation remained statistically significant after adjusting for both body mass index (BMI and sun exposure time. However, disease severity remained significantly higher in southern regions versus central-northern Italy after adjustment also for serum 25OHD levels, age and BMI. In RA Italian patients there are significant regional differences in the prevalence of vitamin D deficiency explained by different BMI, and sun exposure time, and inversely associated with disease activity and disability scores.

    2016-04-01

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

  6. Glycaspis brimblecombei (Hem.: Psyllidae, the invasive red gum lerp psyllid recorded in Italy

    Full Text Available During 2010 in central and southern Italy (Campania, Basilicata and Latium, the invasive red gum lerp psyllid, Glycaspis brimblecombei Moore (Hemiptera: Psyllidae, has been recorder for the first time in Italy. The psyllid was detected on Eucalyptus camaldulensis in several sampling sites. The host plant, like other species of the genus Eucalyptus, is very common in Italy as ornamental and forest species. The native country of G. brimblecombei is Australia, from which the psyllid spread throughout the world in the last decade. In the Palaearctic Region the species was first collected from the Iberian Peninsula in 2007. In this note we report some observations on the biology and distribution of this species in the new colonized Italian areas. Generalist predators, such as wasps and pirate bugs, were observed attacking G. brimblecombei, however no parasitoid activity has been detected.

    Trichinella pseudospiralis is a non-encapsulated species infecting both mammals and birds. In Italy, this parasite was reported only in two night-birds of prey of Central Italy. In January 2010, Trichinella larvae were detected in three wild boars (Sus scrofa) of two regions of Northern Italy by enzymatic digestion. The parasites were identified as T. pseudospiralis by multiplex-PCR. The first infected wild boar was hunted in the Emilia Romagna region and the other two infected wild boars were bred outdoors in a small family farm of the Friuli Venezia Giulia region. These new epidemiological data reinforce the role of the wild boar as the main reservoir of T. pseudospiralis in Europe. PMID:21296503

    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

    headquarters until 9 p.m.: families, school classes with and without teachers, civil protection groups, journalists. This initiative, built up in a few weeks, had a very large feedback, also due to the media highlighting the presumed prediction. Although we could not rule out the possibility of a strong earthquake in central Italy (with effects in Rome) we tried to explain the meaning of short term earthquake prediction vs. probabilistic seismic hazard assessment. Despite many people remained with the fear (many decided to take a day off and leave the town or stay in public parks), we contributed to reduce this feeling and therefore the social cost of this strange Roman day. Moreover, another lesson learned is that these (fortunately sporadic) circumstances, when people's attention is high, are important opportunities for science communication. We thank all the INGV colleagues who contributed to the May 11 Open Day, in particular the Press Office, the Educational and Outreach laboratory, the Graphics Laboratory and SissaMedialab. P.S. no large earthquake happened

  11. Rites of passage in Italy.

    Unlike the vast number of public celebrations in Italy that are almost always associated with specific foods, rites of passage in that country are focused on pivotal private moments after the ceremonial crossing of a threshold; and food may or may not be a primary focus of the event. Recognition of birth, marriage, and death—the three major turning points in the intimate life of a family—may still be observed with dishes or ingredients traceable to the Renaissance, but many older traditions have been modified or forgotten entirely in the last thirty years. Financial constraints once preserved many customs, especially in the south, but regional borders have become porous, and new food trends may no longer reflect the authentic tradition. Can new movements, such as Slow Food, promote ancient values as the form and food of traditional events continue to change? PMID:21495289

  12. CAS Introductory Course in Italy

    2008-01-01

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

    Social inclusion is a multidimensional phenomenon that involves social, political, and economic aspects of individuals' life. While social inclusion is a priority of the European Agenda 2020, little is known about individuals' preferences for social inclusion and its relationship with altruism. We exploit the marked cultural and socio-economic differences between North and South of Italy to investigate the relationship between people's preferences for the social inclusion of juvenile offender...

    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 adage that "people are our greatest asset" has been a recurrent theme in many businesses and organisations through history. This is no less true for a central bank. Indeed, people are, without doubt, a central bank's most important resource. Our business relies heavily on the expertise, experience and sound judgement of our staff. A central bank's effectiveness crucially depends on its credibility, and this in turn largely comes down to the quality of its staff. Therefore, managing human ...

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

    Directory of Open Access Journals (Sweden)

    Lucy Jane Sussex

    2012-11-01

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

  19. The relationship between unemployment and fertility in Italy: A time-series analysis

    2016-01-01

    Full Text Available Background: Many analyses demonstrate that rising unemployment rates generate a feeling of uncertainty that can influence fertility behaviour, inducing a short-term reduction in fertility. The impact of the recent economic crisis in Italy is controversial in the current demographic literature. Objective: We wish to evaluate whether the recent changes in male and female unemployment are differently linked to fertility in different geographic areas of Italy. Methods: We used the following official aggregate data for the period 1995-2012: unemployment quarterly rates from the Labour Force Surveys conducted by the National Institute of Statistics (Istat and quarterly general fertility rates. We applied a monitoring approach for the identification of structural breaks inside both of the time series and used a dynamic regression to identify specific temporal links between unemployment and fertility. Results: Both male and female unemployment rates are negatively associated with fertility in the northern and central regions of Italy. Unemployment rates seem to be good predictors of fertility in these regions, although male unemployment appears to further reduce fertility beyond the reduction predicted by female unemployment. Conclusions: In northern and central Italy, the recent rise in unemployment is negatively correlated with the fertility rate. The recent economic downturn seems to be linked in a more ambiguous and weak way to the fertility rate in the southern area.

    GIOVANNI ZANCHETTA

    2006-03-01

    Full Text Available New stratigraphic data (exposed sections and boreholes allowed a detailed reconstruction of the northern sector of the "Terrazzo di Livorno" (Central Italy. A new unit, called "Corea formation" was discovered and correlated to marine isotope stage (MIS 6 and to its transition to MIS 5. This formation comprises, at its base, fluvial gravels and sands followed by fine-grained alluvial plain deposits. Non-marine molluscs, small mammals and pollen allow a reconstruction of the environment present during the deposition of the alluvial plain deposits. The environment was mainly an open space, though sparse woodlands should have been present. The non-marine fauna shows features intermediate between typical interglacial and glacial assemblages described so far in Italy. Worth of note is the presence of Orcula dolium and Vallonia enniensis, which now inhabit northern Italy. These findings improve our knowledge on the biogeography of Quaternary non-marine faunas of Central Italy. Stable isotopes data on land snail shells, freshwater shells and pedogenic carbonates showed that climate conditions were cooler than today (possibly 1-2°C less with a significant amount of C4 vegetation, in an environment with moderately dry conditions.
