Hydrogeochemical multi-component approach to assess fluids upwelling and mixing in shallow carbonate-evaporitic aquifers (Contursi area, southern Ape…
2023
With the aim of deepening our understanding of deep-seated fluids upwelling and mixing in large regional aquifers, we performed a hydrogeochemical study of twenty-two springs in the Contursi area (upper Sele river valley, southern Apennines) by means of the measurements of chemical-physical parameters, major ions, trace elements, and stable and radioactive isotopes. Besides, we realized two updated geo-structural cross-sections in order to reconstruct the groundwater flowpath in the study area. The hydrogeochemical composition, as well as the water temperature allow to identify-three main groups of groundwater: Cold and Low salinity Groundwater (CLGW), Intermediate Salinity Groundwater (ISG…
Universities’ “Third” Mission, Industrial Conversion and the Quest for Surgical Masks: A Sicilian Tale from the First COVID-19 Lockdown
2022
This contribution is a brief testimony of a “third mission” project conducted in collaboration by two university departments that, despite the operational difficulties, and thanks to institutional support, have promoted an initiative aimed at the productive reconversion of a clothing sector company into a health sector company. The project highlights the benefits of integrating different areas of scientific expertise and highlights the role of full involvement and co-creation of a new production unit. Moreover, it is an example of the role that the university can play in a complex operational context in support of a constructive relationship between public and private actors for the develop…
Red list of threatened vascular plants in Italy
2021
Italy has a rich natural heritage, which is dangerously under pressure. In recent years, there is an increased awareness of the crucial role of plants in ecosystem functioning and in providing ecosystem services. Consequently, an updated Red List of the Italian vascular flora was compiled in this work, at the request of the Ministry for Environment, Land and Sea Protection, with the scientific support of the Italian Botanical Society. The IUCN Red List criteria were applied to 2,430 Italian native vascular plant taxa to assess their current extinction risk and to highlight the major threats affecting the Italian flora. Our results revealed that 54 taxa (2.2% of the assessed taxa) are extinc…

SUMMARY An analysis was made to update the regional red list of endangered vascular plants in Sicily which, with 3,252 taxa (including a noteworthy number of endemic species), is one of the richest areas in the Mediterranean region. Considering previous regional and national red lists, recent taxonomic and floristic lite…

Metodo ed apparato di rilevamento tomografico di una distribuzione di resistività in un mezzo
2008
Metodo di rilevamento tomografico di una distribuzione di resistività di un mezzo comprendente tre fasi: predisposizione su una porzione della superficie del mezzo di una griglia di elettrodi collegati con almeno un generatore elettrico; selezione dalla griglia di una pluralità di secondi elettrodi collegati con un misuratore di potenziale elettrico; immissione attraverso la prima coppia di elettrodi di una corrente elettrica suscettibile di generare un campo elettrico nel mezzo; misurazione dei potenziali elettrici in corrispondenza dei secondi elettrodi per ricavare differenze di potenziale tra coppie a scelta di secondi elettrodi; calcolo della distribuzione di resistività mediante le di…
