Analysis of Operational Parameters in Acid and Base Production Using an Electrodialysis with Bipolar Membranes Pilot Plant
2023
In agreement with the Water Framework Directive, Circular Economy and European Union (EU) Green Deal packages, the EU-funded WATER-MINING project aims to validate next-generation water resource solutions at the pre-commercial demonstration scale in order to provide water management and recovery of valuable materials from alternative sources. In the framework of the WATER-MINING project, desalination brines from the Lampedusa (Italy) seawater reverse osmosis (SWRO) plant will be used to produce freshwater and recover valuable salts by integrating different technologies. In particular, electrodialysis with bipolar membranes (EDBM) will be used to produce chemicals (NaOH and HCl). A novel EDBM…
Diffusion dialysis for the treatment of H2SO4-CuSO4 solutions from electroplating plants: Ions membrane transport characterization and modelling
2021
Diffusion dialysis (DD) is proposed to separate and recover mineral acids and transition metals from electroplating industry process waters promoting a circular approach of resources recovery. In this work, a DD module with two anionic membranes (Fumasep FAD and Neosepta AFN) are used for the separation of H2SO4 from Cu2+ containing solutions. The membrane performances with sole H2SO4 solutions (0.2–2 M) and sole CuSO4 solutions (0.8–1.1 M Cu2+) and with mixtures of H2SO4 (0.6 M) and CuSO4 (0.2–1.1 M Cu2+) as feed are studied. H2SO4 recovery efficiency decreases as the concentration of acid increases. For H2SO4 solutions, the water drag flux from the retentate to the diffusate prevails agai…
Monitoring tropical forests under a functional perspective with satellite-based vegetation optical depth.
2020
Monitoring ecosystem functions in forests is a priority in a climate change scenario, as climate-induced events may initially alter the functions more than slow-changing attributes, such as biomass. The ecosystem functional properties (EFPs) are quantities that characterize key ecosystem processes. They can be derived by point observations of gas and energy exchanges between the ecosystems and the atmosphere that are collected globally at FLUXNET flux tower sites and upscaled at ecosystem level. The properties here considered describe the ability of ecosystems to optimize the use of resources for carbon uptake. They represent functional forest information, are dependent on environmental dri…
A repository of fragments for agent systems design
2006
The creation of a new design process for a specific situation using the method engineering approach is based on the composition of a set of reusable method fragments. The request for these reusable method fragments leads to the need for a repository containing standardized fragments that can be easily selected and assembled in new design processes. In this work we present a definition of method fragment coming from the work of the FIPA Technical Committee Methodology and a repository where fragments are classified according to the specific process component (activity, process role, and work product) they underpin and on the specific MAS Metamodel element(s) they work on.
Image Segmentation through a Hierarchy of Minimum Spanning Trees
2012
Many approaches have been adopted to solve the problem of image segmentation. Among them a noticeable part is based on graph theory casting the pixels as nodes in a graph. This paper proposes an algorithm to select clusters in the images (corresponding to relevant segments in the image) corresponding to the areas induced in the images through the search of the Minimum Spanning Tree (MST). In particular is is based on a clustering algorithm that extracts clusters computing a hierarchy of Minimum Spanning Trees. The main drawback of this previous algorithm is that the dimension of the cluster is not predictable and a relevant portion of found clusters can be composed by micro-clusters that ar…
Lo sviluppo e l’innovazione
2021
Le norme della legge di bilancio per il 2021 in materia di sviluppo e innovazione sembrano ancora legate a una logica di natura emergenziale, ponendosi in continuitàconle normative adottate nel corso del 2020 per fare fronte alle fasi più acute della crisi causata dal Covid-19, con le quali, non a caso, condividono il carattere temporaneo degli interventi. Questi si basano su incentivi ai consumi, garanzie pubbliche sui prestiti bancari e varie provvidenze da distribuire tramite fondi pubblici appositamente istituiti. Sorprende l’assenza di progetti ambiziosi per lo sviluppo economico, che avrebbero potuto essere coordinati, o costituire anticipazioni, di quelli da inserire successivamente …
Libertà della persona nell’uso delle tecnologie digitali: verso nuovi orizzonti di tutela nell’accertamento penale
2020
L’ormai diffuso utilizzo di tecnologie digitali apre la via a moderne modalità investigative, che trovano un necessario limite nel rispetto delle libertà delle persone coinvolte. Sono libertà che se, da un lato, possono essere ricondotte ai principi costituzionali tradizionalmente in gioco nel procedimento penale, dall’altro lato, chiamano in causa garanzie inedite, a presidio di una “nuova” sfera di intimità da proteggere. The widespread use of digital technologies opens the way to new investigative methods that find a limit in the respect of concerned persons freedoms. These freedoms, on one side, are related to constitutionals principles traditionally under play in criminal proceedings. …
Introduction: Mediterranean Movements and the Reconfiguration of the Military-Humanitarian Border in 2015
2018
This article deals with the transformations occurred in the government of refugees in the Mediterranean since 2013, when the military-humanitarian operation Mare Nostrum was launched by the European Union. The paper analyses how military and humanitarian practices are entangled in governing refugees and develops the notion of military-humanitarianism. The Mediterranean borderzone has undergone radical reconfigurations over the last few years. Particularly, new technologies of control for strengthening the role of the Mediterranean Sea as a pre-frontier of Europe have been put in place. The production and the declaration of a "refugee crisis" in Europe has contributed to producing important …
Prehistoric Settlement and Population in the Madonie Mountains. New Data from the Archaeological Survey
2010
The aim of the Madonie research project is to analyse mobility strategies and the use of a mountainous territory by relating geomorphologic features, raw material sources and landscape to the prehistoric settlement. For this purpose we planned an intensive and systematic survey of sample areas, selected on geo-morphological, altimetric and archaeological criteria, correlated to a palaeoenvironmental investigation based on the study of palynological sequence samples coming from wet areas of the Madonie territory and from archaeological deposits. Le projet de recherche sur la Madonie analyse les stratégies de mobilité et l’exploitation du territoire de montagne, en reliant les caractéristique…
