Electrodialysis for water desalination: A critical assessment of recent developments on process fundamentals, models and applications
2018
Abstract The need for unconventional sources of fresh water is pushing a fast development of desalination technologies, which proved to be able to face and solve the problem of water scarcity in many dry areas of the planet. Membrane desalination technologies are nowadays leading the market and, among these, electrodialysis (ED) plays an important role, especially for brackish water desalination, thanks to its robustness, extreme flexibility and broad range of applications. In fact, many ED-related processes have been presented, based on the use of Ion Exchange Membranes (IEMs), which are significantly boosting the development of ED-related technologies. This paper presents the fundamentals…
Electrodialysis Applications in Wastewater Treatment for Environmental Protection and Resources Recovery: A Systematic Review on Progress and Perspec…
2020
This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and othe…
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…
Pro e contro dei rimedi domestici: prospettive di sinergia europea nel contenzioso climatico collettivo
2023
Human rights-based national climate litigation is a growing phenomenon. In Europe, this type of litigation is essentially based on the case law of the European Court of Human Rights, whose human rights obligations are used as a means of interpreting climate obligations of States towards their citizens. The analysis of domestic jurisprudence produces a complex picture. On the one hand, we find elements facilitating access to environmental justice, such as more flexible eligibility criteria and the issuing of immediately enforceable judgments. On the other hand, this comes up against obstacles arising from the risk of the lack of impact that a single decision may have. A possible solution to …
Vulnerability, Human Rights and Climate Change
2021
The article aims at establishing the specificity of the human rights approach to environmental issues such as the climate change, in order to test its advantages and limits. While responsibilities in the side of climate change is controversial, the approach from human rights and in particular from their vulnerability is easier to focus and define and it involves also the problem of inequalities produced by the degradation of environment. In addition, the human rights approach is dynamic (open to specification and to proceses of implementation) and it is compatible with an intergenerational perspective.
The beginning of the Neolithic in Southern Italy and Sicily
2018
Abstract The process of Neolithization of Southern Italy and Sicily covers about 500 years (6200–5700 cal BC) and involves two cultural horizons: Archaic Impressed Ware or “Impresse Arcaiche” and Advanced Impressed Ware or “Impresse Evolute”. In Southern Italy the Neolithic peopling from the East is characterized by a “package” of plenty domesticated plants and livestock; in Sicily the adoption of the new economical system is apparently more slow and with no evidences of ruptures between the Mesolithic groups and first farmers. In this paper we present the chronological and cultural framework of the sixth millennium BC within the area of investigation, with an up-to-date bibliography about …
The small mammals (insectivores, bats and rodents) from the Holocene site of Vallone Inferno (Scillato, Sicily)
2013
The Vallone Inferno rock-shelter is an archeological site located at 770 m a.s.l. in the Madonie massif in Sicily. This massif is modeled into the Triassic and Oligocene sedimentary rocks of the Imerese Basin. Thearchaeological excavations conducted since 2008 have provided a long prehistoric and historic sequence from the Neolithic to the medieval period. From the four sedimentary complexes identified, only levels 3.4 to 3.1 from complex 3 and 4.2 from complex 4 have yielded small-mammal material. Level 4.2 is poor in remains and as yet without cultural ascription, though it has a radiocarbon age of 9450±50 years BP. Level 3.4 has yielded fragments of ceramic characteristic of the Middle N…
Inferni di ghiaccio: qualche nota sui "Kolymskie rasskazy" di V. T. Šalamov.
2009
V. T. Šalamov sperimentò la crudeltà della regione siberiana della Kolyma, dove venne recluso come prigioniero politico per 17 anni. L'articolo mira a chiarire in tre suoi racconti dei "Kolymskie rasskazy"(Plotniki, Prokurator Iudei, Sentencija) come il clima gelido siberiano giochi un ruolo di rappresentazione metaforica e simbolica della assurda violenza dei Gulag stalinaiani. Inoltre lo scopo di questo saggio sta nel sottolineare come Šalamov in questi brevi racconti, prova e memoria di un enorme genocidio,impieghi per la sua scrittura artistica differenti aspetti del clima delle regioni siberiane come essenziali elementi per mostrare la capacità dell'uomo di reagire, scoprendo nella pro…
GLI ANTROPOLOGI SOCIOCULTURALI E LA “SOSTENIBILITÀ”. ALCUNE PROSPETTIVE
2023
The chapter proposes a critical discussion of the notions of sustainability and sustainable development. It should be noted that the global and national policies of "sustainable development" implemented in the last thirty years have failed to stop the worsening of the planetary crisis and of climate change of anthropogenic origin at the planetary level. We then go over some of the main lines of reflection and analysis on these issues within socio-cultural anthropology
Performative Habitats and the aesthetics of ordinary gestures
2022
Il saggio analizza il progetto artistico di Egle Oddo, Performative Habitats, alla luce dell’estetica dei gesti ordinari. Con Performative Habitats biologia, botanica e scienze naturali incontrano i molteplici linguaggi delle discipline artistiche. In un momento storico in cui il cambiamento climatico è tra le emergenze primarie, l’artista si prefigge l’obiettivo di riconvertire le pratiche quotidiane e stabilire nuove modalità di produzione artistica che siano sostenibili per l’ambiente. The essay explores Egle Oddo's artistic project, Performative Habitats, in light of the aesthetics of ordinary gestures. With Performative Habitats biology, botany and natural sciences meet the multiple la…
