Towards a Geological Information System: the CARGeo System and the Regione Lombardia Geological Database.

In the framework of the national mapping program «CARGNew Italian Geological Map at 1:50.000 scale», Regione Lombardia is generating a detailed map (1:10.000 scale) of its territory. Surveying criteria have been carefully defined in order to produce homogeneous geological maps: geological survey has been performed at the 1:10.000 scale, and data have been stored in a GIS-oriented database. The detailed survey scale improved the geological knowledge: the new maps represent an important tool for territorial planning requirements of public administrations and engineering geologists (e.g. in hydrogeological and seismic risk evaluation). Field geologists performed data input in the geological data base by alternating field campaigns and data input throughout the year, taking advantage of periods when field activities are slackened (i.e. according to climate conditions). In this way, data entry is nearly synchronous with data collection, and field data become quickly accessible. Data entry by the field geologists on one side slows down the field activity, however, it guarantees a precise digitalization of geometric data and a correct attribute assignment, allowing to optimize working time. To allow the data entry to non-GIS-specialized users, we developed an ArcView®-VisualBasic®-MSAccess® application, enabling the simultaneous acquisition of geometric and alphanumeric data. Data base management and cartographic production are performed with ArcInfo®, through specific procedures which, after data reorganization and control (both alphanumeric and geometric), lead to the final cartographic output at different scales. The 1:10.000 geological database is migrated in the ArcSDE structure and prepared for data view, query and download (www.cartografia.regione.lombardia.it/cargweb) using ESRI (ArcIMS) tools. From the 1:10.000 geological database we derived the database for the 1:50.000 CARG maps by both automatic and manual generalization according to the CARG-APAT standards. During the different phases of the project, several problems arose, due to both project organization and data storage system (from data collection in the field to elaboration and digitalization, and, in case, to final publication). – Data collection: the survey activity was divided between «bedrock » and «quaternary» specialists. The double survey provided a high-quality geological description of the territory, but slowed the generation of the data-flow. Based on this experience, the last assigned areas are surveyed by a single geologist, under the supervision of quaternary and bedrock experts. – Users feedback: geologists are normally used to draw their maps on paper; learning how to produce electronic maps can be difficult, and the software tools have to be studied very carefully and present user friendly interfaces. Nevertheless, in our experience, a training period has to be planned, and geologists have to be supported by a GIS expert, who can understand their needs and modify the software accordingly. – System architecture: the ArcView®-VisualBasic®-MSAccess® (Windows platform) – ArcInfo® (UNIX platform) environment, revealed problems in the client-server stability of an earlier version; some unsolved troubles remain, mainly related to the network architecture. The presence in the CARG-Regione Lombardia crew of consultant geologists, experienced and trained in collection, analysis and data entry in the final database, accelerated the critical phases of: – Data base derivation from Regione Lombardia dataset to CARG-APAT standard

A compact light readout system for longitudinally segmented shashlik calorimeters

The longitudinal segmentation of shashlik calorimeters is challenged by dead zones and non-uniformities introduced by the light collection and readout system. This limitation can be overcome by direct fiber-photosensor coupling, avoiding routing and bundling of the wavelength shifter fibers and embedding ultra-compact photosensors (SiPMs) in the bulk of the calorimeter. We present the first experimental test of this readout scheme performed at the CERN PS-T9 beamline in 2015 with negative particles in the 1-5~GeV energy range. In this paper, we demonstrate that the scheme does not compromise the energy resolution and linearity compared with standard light collection and readout systems. In addition, we study the performance of the calorimeter for partially contained charged hadrons to assess the $e/\pi$ separation capability and the response of the photosensors to direct ionization.Comment: To appear in Nuclear Instruments and Methods in Physics Research,

I sistemi carbonatici giurassici della Sardegna orientale (Golfo di Orosei) ed eventi deposizionali nel sistema carbonatico giurassico-cretacico della Nurra (Sardegna nord-occidentale)

This field trip gives a panoramic of the facies association and sedimentological-stratigraphic evolution of Jurassic-Cretaceous depositional systems of eastern (Golfo di Orosei) and western (Nurra) Sardinia. Carbonate deposition in western Sardinia occurred in an epeiric sea during Jurassic and Cretaceous whereas carbonates of the eastern Sardinia figure out a complex depositional settings with intraplatformal basins facing the Alpine Tethys from a basal transgression in the Bajocian to Berriasian. The presence of partly coeval succession allows a comparison between these two depositional systems and highlights relation with global and regional events. The Jurassic-Cretaceous carbonate succession of Sardinia shows similarities with coeval succession of the Provencal-Pyrenean domain (Nurra), nevertheless differences, both in terms of facies characters and distribution and range of stratigraphic gaps, occur between the successions of eastern Sardinia. These differences can be ascribed to different paleogeographic and depositional settings

A narrow band neutrino beam with high precision flux measurements

The ENUBET facility is a proposed narrow band neutrino beam where lepton production is monitored at single particle level in the instrumented decay tunnel. This facility addresses simultaneously the two most important challenges for the next generation of cross section experiments: a superior control of the flux and flavor composition at source and a high level of tunability and precision in the selection of the energy of the outcoming neutrinos. We report here the latest results in the development and test of the instrumentation for the decay tunnel. Special emphasis is given to irradiation tests of the photo-sensors performed at INFN-LNL and CERN in 2017 and to the first application of polysiloxane-based scintillators in high energy physics.Comment: Poster presented at NuPhys2017 (London, 20-22 December 2017). 5 pages, 2 figure

Diamond-Based Thin Film Bulk Acoustic Wave Resonator for Biomedical Applications

Nowadays it is in constant growing the development of thin film bulk acoustic resonators. If the piezoelectric material is going to be implanted in the human body, an important requirement is the biocompatibility of the implant. In this regard, Aluminum Nitride (AlN) has emerged as an attractive alternative for use in biomedical MicroElectroMechanical Systems. Ultrananocrystalline Diamond (UNCD) is a promising material to be used in biomedical applications, due to its extraordinary mulifunctionality; it is exceptional for implantable medical devices requiring stringent biological performance. Since both UNCD and AlN films can be processed via photolithography processes used in microfabrication, the integration of UNCD and AlN films provides the bases for developing a new generation of biocompatible Bio-MEMS/NEMS. Research and development was conducted to produce implantable MEMS devices: Pt/piezoelectric AlN/Pt layer heterostructure was grown and patterned on the UNCD membrane with a Ti adhesion layer. By applying voltages between the top and bottom Pt electrodes layers the piezoelectric AlN layer is energized. The feasibility of the fabrication of biocompatible AlN/diamond-based FBAR structure has been demonstrated.Fil: Zalazar, Martin. Universidad Nacional de Entre Rios. Facultad de Ingenieria.

A survey of clinical features of allergic rhinitis in adults

Background: Allergic rhinitis (AR) has high prevalence and substantial socio-economic burden. Material/Methods: The study included 35 Italian Centers recruiting an overall number of 3383 adult patients with rhinitis (48% males, 52% females, mean age 29.1, range 18–45 years). For each patient, the attending physician had to fill in a standardized questionnaire, covering, in particular, some issues such as the ARIA classification of allergic rhinitis (AR), the results of skin prick test (SPT), the kind of treatment, the response to treatment, and the satisfaction with treatment. Results: Out of the 3383 patients with rhinitis, 2788 (82.4%) had AR: 311 (11.5%) had a mild intermittent, 229 (8.8%) a mild persistent, 636 (23.5%) a moderate-severe intermittent, and 1518 (56.1%) a moderate-severe persistent form. The most frequently used drugs were oral antihistamines (77.1%) and topical corticosteroids (60.8%). The response to treatment was judged as excellent in 12.2%, good in 41.3%, fair in 31.2%, poor in 14.5%, and very bad in 0.8% of subjects. The rate of treatment dissatisfaction was significantly higher in patients with moderate-to-severe AR than in patients with mild AR (p<0.0001). Indication to allergen immunotherapy (AIT) was significantly more frequent (p<0.01) in patients with severe AR than with mild AR. . Conclusions: These fndings confirm the appropriateness of ARIA guidelines in classifying the AR patients and the association of severe symptoms with unsuccessful drug treatment. The optimal targeting of patients to be treated with AIT needs to be reassessed

Allergy in adolescent population (14-18 years) living in campania region (southern Italy). a multicenter study

Adolescents (Ad) constitute a difficult to manage population among individuals suffering from asthma. The aim of our study was to assess the prevalence, clinical characteristics and age of onset of allergic sensitization and clinical symptoms in a sample of atopic Ad living in the Campania region (Southern Italy). Sixteen Allergy units or Centers belonging to the Italian Association of Hospital and Territorial Allergologists (AAIITO, Campania region) participated in this cross-sectional study. A case report form (CRF) was specifically designed for this study and commercial allergen extracts used for screening SPTs were provided by ALK-Abelló Group (Milan, Italy). A total of 443 patients were examined (females, f 220, 49.6 %; males, m 223, 50.3%). Dust mites represent the most common sensitizing agents in allergic Ad living in Campania region (Dermatoph. pteronyssinus 67.4% and Dermatoph. farinae 66.5%), followed by Parietaria (58.9%), grasses (45.8%), Artemisia vulgaris (16.7%), Olea Europaea (32.2%), dog dander (17.1%), cat dander (20.0%), Alternaria alternata (8.1%), Cupressus sempervirens (4.9%), Betula pendula (4.7%), other allergens (19.4%). An interesting comparison has been made between clinical data of our Ad with data of elderly patients (E). The role of allergic sensitization is significantly higher in Ad compared to E. Dermatophagoides pteronyssinus is the first sensitizing allergen in Ad and the last in E. Parietaria constitutes the first sensitizing pollen both in Ad and E, the percentage of sensitization is higher in Ad. Another important difference is the higher prevalence of As, as only symptom, in E compared to Ad (19.7% versus 7.6%). In conclusion, our findings confirm the high prevalence and clinical significance of airway allergic sensitization in the adolescents living in Campania region

The Genome of the Toluene-Degrading Pseudomonas veronii Strain 1YdBTEX2 and Its Differential Gene Expression in Contaminated Sand.

The natural restoration of soils polluted by aromatic hydrocarbons such as benzene, toluene, ethylbenzene and m- and p-xylene (BTEX) may be accelerated by inoculation of specific biodegraders (bioaugmentation). Bioaugmentation mainly involves introducing bacteria that deploy their metabolic properties and adaptation potential to survive and propagate in the contaminated environment by degrading the pollutant. In order to better understand the adaptive response of cells during a transition to contaminated material, we analyzed here the genome and short-term (1 h) changes in genome-wide gene expression of the BTEX-degrading bacterium Pseudomonas veronii 1YdBTEX2 in non-sterile soil and liquid medium, both in presence or absence of toluene. We obtained a gapless genome sequence of P. veronii 1YdBTEX2 covering three individual replicons with a total size of 8 Mb, two of which are largely unrelated to current known bacterial replicons. One-hour exposure to toluene, both in soil and liquid, triggered massive transcription (up to 208-fold induction) of multiple gene clusters, such as toluene degradation pathway(s), chemotaxis and toluene efflux pumps. This clearly underlines their key role in the adaptive response to toluene. In comparison to liquid medium, cells in soil drastically changed expression of genes involved in membrane functioning (e.g., lipid composition, lipid metabolism, cell fatty acid synthesis), osmotic stress response (e.g., polyamine or trehalose synthesis, uptake of potassium) and putrescine metabolism, highlighting the immediate response mechanisms of P. veronii 1YdBTEX2 for successful establishment in polluted soil
