    Multi-hazard risk pathway scenarios associated with unconventional gas development: Identification and challenges for their assessment (2021)
    ScienceDirect | Elsevier
    Details
    Publication Date: 2021-06-07
    Description: In this paper we summarize a number of risk pathway scenarios that are often claimed in literature as of priority for risk analyses in unconventional gas development. The resulting scenarios are structured in diagrams representing causal relationships between events. We argue that science is called to fill gaps regarding the main processes characterizing the involved events and defining the conditions under which their occurrence may be enhanced or inhibited. In this way, these scenarios can be more objectively parameterized, making their quantitative assessment a more feasible task and opening the way for the formulation of appropriate risk mitigation strategies.

    The ARGO Project: assessing NA-TECH risks on offshore oil platforms (2021)
    Elsevier
    Details
    Publication Date: 2021-06-07
    Description: Analysis of natural and anthRopoGenic risks on Offshore platforms (ARGO) is a 3-years project, funded by the Italian Ministry of Economic Development. The project, coordinated by AMRA, a permanent Research Centre for the development of innovative technologies applied to environmental problems, aims at providing technical-support for the analysis of natural and anthropogenic risks on offshore oil-platforms. ARGO has developed methodologies for the probabilistic analysis of industrial accidents triggered by natural events (NA-TECH) on offshore platforms. The final analysis of the ARGO Project suggest a constant monitoring of exploitation activity, fluids re-injection and storage using high technology networks.

    Scintillation modeling (2021)
    Elsevier
    Details
    Publication Date: 2021-01-07
    Description: In this chapter, some scintillation models are described, taking into account of the dynamical nature of the Earth's ionosphere and its “complexity.” After a short description of the problem, a detailed explanation is provided about the propagation model named WAM, after its authors Wernik, Alfonsi, and Materassi. WAM is a propagation model based on a phase screen approach, where the statistical characteristics of the screen are constructed according to in situ data of ionospheric irregularities. Then, the Ground-Based Scintillation Climatology (GBSC) model is presented; this is a tool based on a wide statistical database from high performance receivers.

    High-latitude polar pattern of ionospheric electron density: Scaling features and IMF dependence (2021)
    Elsevier
    Details
    Publication Date: 2021-05-12
    Description: We investigated the average polar patterns of ionospheric electron density and the corresponding patterns of scaling features as a function of interplanetary magnetic field orientation. The focus is on the Northern Hemisphere using electron density data recorded on-board ESA Swarm A satellite. The first- and second-order scaling exponents have been evaluated by means of the -order structure functions. We used electron density measurements over a period of 15 months from April 1, 2014 to June 30, 2015, which corresponds to the maximum of solar cycle 24 and which is characterized by an average value of the solar radio flux (F10.7) index equal to (140+/- 30) sfu. Electron density, first- and second-order scaling exponents have been mapped and discussed for four main IMF orientations provided by Bx and By components under conditions of high solar activity. Large spatial changes of the second-order scaling exponent pattern are observed with a steepening of the associated spectral exponent in correspondence with the nightside polar cap trailing edge. Intermittency, defined as the departure from linearity of the dependence of scaling exponents on moment order q, is also evaluated finding that it is generally higher near the equatorward boundary of the auroral oval than elsewhere. On the whole, the found patterns of the electron density first- and second-order scaling exponents suggest the occurrence of turbulence at the high latitudes.
