A Seismic Geotechnical Hazard Study in the Ancient City of Noto (Italy)

Abstract South-Eastern Sicily has been affected in past times by several destroying earthquakes with high values of estimated magnitude. The aim of the seismic hazard microzonation studies performed at the City of Noto is to quantify the spatial variability of the site response on some typical historical scenario earthquakes that would be expected in the area. In order to quantify the expected ground motion, the manner in which the seismic signal is propagating through the subsurface has been defined. Propagation is particularly affected by the local geology and by the geotechnical dynamic ground conditions of the studied area. The data largely consist of the stratigraphic profiles obtained by in situ tests i.e. borings, MASW tests, Down-Hole tests, SDMT tests; some are accompanied by static and dynamic laboratory tests, such as Resonant Column, monotonic compression loading Triaxial tests and Direct shear tests. Processing of all these data allowed the ground response analysis at the surface, in terms of time history and response spectra, of some areas of the city using the linear-equivalent codes EERA, STRATA and DEEPSOIL, useful for microzonation of seismic geotechnical hazards

The appeal of neo-fascism in times of crisis. The experience of CasaPound Italia

The present works sets up to analyze the relationship between radical right activism and the unfolding of the financial crisis in Europe, investigating the extent to which the current economic circumstances have influenced right-wing movements’ political supply and repertoires of action. Using the case study of the Italian neo-fascist group CasaPound, and based on a mix of historiography and ethnographic methods, the present work systematically analyzes the ways in which the group tackles the economic crisis. We find that the crisis offers a whole new set of opportunities for the radical right to reconnect with its fascist legacy, and to develop and innovate crisis-related policy proposals and practices. The crisis shapes the groups’ self-understanding and its practices of identity building, both in terms of collective rediscovery of the fascist regime’s legislation, and in terms of promotion of the fascist model as a ‘third way’ alternative to market capitalism. Even more importantly, the financial crisis plays the role of the enemy against which the fascist identity is built, and enables neo-fascist movements to selectively reproduce their identity and ideology within its practices of protest, propaganda, and consensus building

Soil Liquefaction and Risk Analysis From in Situ Tests for the City of Trapani (Italy)

The paper deals with a microzoning criterion based on CPT data to define liquefaction risk of the city of Trapani, Sicily (Italy). Zonation for liquefaction is a fundamental issue to prevent from seismic disasters since, as lessons of past earthquakes teach, liquefaction of sandy soils has been a major cause of damage to buildings. For the evaluation of the seismic risk of the municipal area of Trapani it has been chosen a scenario earthquake which may represent a possible repetition of the 1968 event. For this earthquake a Richter magnitude M= 6.0 and a maximum ground acceleration amax-= 0.30g have been estimated. While new tools and refinements continue to be developed on the subjects of pore pressure build-up due to earthquake shaking and of liquefaction triggering, reliable evaluation methods already exist for liquefaction microzonation purposes. This study focuses on the application of a method for the evaluation of the liquefaction potential to several sites of the city of Trapani, by means of relationships between liquefaction resistance and corrected cone penetration tests (CPT) resistance

Modelling of a Debris Flow Event in the Enna Area for Hazard Assessment

Abstract In the paper a modelling of a real debris flow in the Enna area in the south of Italy is described. Starting from the study of the geological framework and the historical background for landslides of the Enna district, the research has focused on the causes triggering the landslides. In order to study the performance of debris flow, the real case of 1 st -2 nd February 2014 which affected Enna city has been modeled. The event caused damage to private buildings and above all the interruption of the main infrastructure connecting Enna city at the motorway, due to the material on the road. The modelling of the real debris flow using a mono-phase model (FLO-2D) was carried out in order to investigate the global dynamic of the event. The study allows to acquire a better knowledge of the hydraulic parameters that can be used in other modelling events for areas with a similar soil composition in order to assess the most appropriate mitigation works, reducing damage to structures and infrastructures

Estimate of Uncertainty of Measurement from a Single-Laboratory Validation Study: Application to the Determination of Lead in Blood

Abstract Background: Lead is an environmental pollutant, and human exposure is assessed by monitoring lead concentrations in blood. Because the main source of environmental exposure has been the use of leaded gasoline, its phase-out has led to decreased lead concentrations in the general population. Therefore, validated analytical methods for the determination of lower lead concentrations in blood (<150 μg/L) are needed. In addition, new ISO standards require that laboratories determine and specify the uncertainty of their results. Methods: We validated a method to determine lead in blood at concentrations up to 150 μg/L by electrothermal atomic absorption spectrometry with Zeeman background correction according to EURACHEM guidelines. Blood samples were diluted (1:1 by volume) with 2 mL/L Triton X-100. NH4H2PO4 (5 g/L) and Mg(NO3)2 (0.5 g/L) were used as modifiers. Matrix-matched standards were used for calibration. Results: We determined the limits of detection (3.1 μg/L) and quantification (9.4 μg/L). Repeatability and intermediate imprecision within the range 35–150 μg/L were <5.5% and <6.0%, respectively. We assessed trueness by use of certified reference materials, by recovery tests, and by comparison with target values of other reference materials (candidate external quality assessment samples). The expanded uncertainty ranged from 20% to 16% (with a confidence level of 95%) depending on concentration. Conclusions: This study provides a working example of the estimate of uncertainty from method performance data according to the EURACHEM/CITAC guidelines. The estimated uncertainty is compatible with quality specifications for the analysis of lead in blood adopted in the US and the European Union

Smart Specialisation, seizing new industrial opportunities

This study offers a novel analytical approach to inform the regional search for new industrial opportunities, as promoted by smart specialisation in the EU Cohesion policy context. The analysis departs from the challenges of practicing smart specialisation and its entrepreneurial discovery process in a dynamic perspective. It argues that the adoption of a dynamic approach to identify new opportunities implies mapping regional business and innovation assets as well as, assessing their position within the global technological and industrial landscape. The study brings a case study of Lombardy region, spurring the S3 Lab initiative (in collaboration with Baden-Württemberg, Catalonia and Lapland), together with a comparative analysis of its technological profile. The empirical study combines patent data from OECD REGPAT and territorial proprietary micro-data from Lombardy region on firm creation in emerging industries (EI) – new industrial sectors or existing sectors evolving into new industries (European Cluster Observatory). These industries represent a priority area for Lombardy's innovation-led development strategy. The initial observations confirm the importance of such industries in the region; they represent more than one-third of employment, almost a half of the regional value-added and feature together the majority of start-ups, suggesting the relevance of the regional strategic development choices. Also, in terms of productive advantages, Lombardy ranks high in some key EI. The mapping of technological competences through patent indicators, e.g. specialisation, diversification and ability to specialise in fast-growing and niche fields gives relevant insights on the technological potential of the region, providing further guidance for better targeted interventions.JRC.B.3-Territorial Developmen

A review of minimally invasive fracture stabilization in dogs and cats

Objective: To summarize and discuss peer-reviewed studies on minimally invasive osteosynthesis (MIO) of long bone, physeal, and articular fractures in dogs and cats. Study design: Invited review. Methods: A critique of literature was performed to assess MIO feasibility, outcomes, and complications through PubMed, Scopus, and CAB abstracts research databases (2000-2020). Results: More than 40 MIO articles have been published in the last 15 years, but most studies had small numbers, lacked control groups, and used limited outcome measures. Studies generally showed that MIO was feasible in dogs and cats with low complication rates. The current evidence does not demonstrate superior bone healing or functional outcomes with MIO when compared to standard methods. Although treatment principles, case selection, and techniques varied depending on the anatomical location, there were no salient differences in complication rates among long bones, physeal, and articular fractures treated by MIO. Conclusion: The current available evidence and the personal experience of the authors support MIO as a promising fracture management modality. MIO can yield excellent outcomes when applied in carefully selected cases, performed by surgeons experienced in the technique. We cannot, however, conclude that MIO is superior to open fracture stabilization based on the available evidence in veterinary literature. Randomized controlled studies are warranted to prospectively compare MIO with other osteosynthesis techniques and thereby validate its role in fracture management for dogs and cats

Analysis of NO2 and O3 Total Columns from DOAS Zenith-Sky Measurements in South Italy

The Gas Absorption Spectrometer Correlating Optical Difference—New Generation 4 (GASCOD/NG4) is a multi-axis differential optical absorption spectroscopy (MAX-DOAS) instrument which measures diffuse solar spectra at the Environmental-Climate Observatory (ECO) of the Italian research institute CNR-ISAC, near Lecce. The high-resolution spectra measured in zenith-sky configuration were used to retrieve the NO2 and O3 vertical column densities (VCDs) from March 2017 to November 2019. These good-quality data, proven by the comparison with the Ozone Monitoring Instrument (OMI) and TROPOspheric Monitoring Instrument (TROPOMI) satellite measurements, were used to characterize the ECO site by exploiting the sinergy with in situ NO2 and O3 concentrations and meteorological data. Although stratospheric processes seem to be the main forces behind the NO2 and O3 VCDs seasonal trends, diurnal variabilities revealed the presence of a tropospheric signal in the NO2 VCDs, which had significant lower values during Sundays. Comparison with wind data acquired at the ECO observatory, at 20 m above the ground, revealed how NO2 VCDs are influenced by both tropospheric local production and transport from the nearby city of Lecce. On the other hand, no significant tropospheric signal was contained in the O3 VCDs

Comparison between high-field 3 Tesla MRI and computed tomography with and without arthrography for visualization of canine carpal ligaments: a cadaveric study

OBJECTIVE:To compare the quality of visualization of canine carpal ligaments by using computed tomography (CT), MRI, CT arthrography (CTA), and magnetic resonance arthrography (MRA). STUDY DESIGN: Prospective descriptive study. STUDY POPULATION: Cadavers from dogs weighing more than 20 kg. METHODS: A 16-slice CT scanner and a 3 Tesla MRI were used for the investigation. A dilute contrast medium was injected into the middle carpal and radiocarpal joints under fluoroscopic control, and CTA and MRA images were acquired. To evaluate the difference between imaging modalities, 3 observers graded carpal ligaments of clinical interest using a scale from 0 to 4 for their quality of visualization. Data were analyzed by using a random-effect ordinal logistic regression with Bonferroni adjustment. The interobserver agreement was calculated by using the weighted Cohen's κ. RESULTS: Normal carpal joints (n = 9) were investigated. Magnetic resonance arthrography improved visualization of the majority of carpal ligaments compared with MRI (P < .05) and offered the best visualization overall. Magnetic resonance imaging and MRA offered better visualization compared with both CT and CTA (P < .05). There was no difference between CT and CTA. Interobserver agreement was discrete (0.2 < κ ≤ 0.4) for all observers. CONCLUSION: Arthrography improved the capabilities of MRI but not of CT for visualization of the canine carpal ligaments. Magnetic resonance arthrography was particularly useful for evaluation of the stabilizers of the antebrachiocarpal joint. CLINICAL SIGNIFICANCE: 3 Tesla MRA and MRI allow excellent visualization of the ligamentous morphology and may be helpful in the diagnostic process of carpal sprains in dogs
