Martyrdom in Contemporary Animalist Discourses
2019
Is it possible to use the notion of martyrdom in order to explain the communicative strategies and the semiotic mechanisms of the animalist movement? Is the animal a sort of contemporary martyr? This study aims to apply the notion of martyrdom outside the traditional boundaries of religion and politics, testing it in another relevant socio–cultural phenomenon: the contemporary animalist discourse. This paper analyses texts from animalist advertising, essays and novels promoting animal rights and vegetarianism. The main features of the traditional notion of martyrdom are compared to the semiotic structures of the animalist discourse. The questions of the efficacy of images and that of the ex…
Recovery of Lithium Carbonate from Dilute Li-Rich Brine via Homogenous and Heterogeneous Precipitation
2022
An extensive experimental campaign on Li recovery from relatively dilute LiCl solutions (i.e., Li+ similar to 4000 ppm) is presented to identify the best operating conditions for a Li2CO3 crystallization unit. Lithium is currently mainly produced via solar evaporation, purification, and precipitation from highly concentrated Li brines located in a few world areas. The process requires large surfaces and long times (18-24 months) to concentrate Li` up to 20,000 ppm. The present work investigates two separation routes to extract Li+ from synthetic solutions, mimicking those obtained from low-content Li+ sources through selective Li+ separation and further concentration steps: (i) addition of …
Anthropocène, Sémiotique et Droit de l’Environnement. La remise en cause juridique des non-humains
2023
The Anthropocene is not a time of a crisis of nature, but a time of an epistemic one. That stimulates the semiotics of culture to take up the project of an archaeology of knowledge. In this article, we give some indications of how to deal with this in the discourse of environmental law. We will focus on the turning point of the 1960s and 1970s, which is very significant for environmental law. Based on a corpus including French national law, international law and European regulations, we will start by proposing a semiotic genealogy of natural spaces ; then, we will show how it leads to the reformulation of legal temporalities ; finally, we will end by evoking its repercussions on the actoria…

In vitro Antifungal Activity of Biopolymeric Foam Activated with Carvacrol
2020
Background: Active packaging represents a defining strategy to improve food quality and safety of the packaged foods. This study aimed to evaluate the in vitro ability of commercial biopolymeric foams, namely Mater-Bi (MB), activated with 20% of carvacrol, to develop a completely biodegradable and compostable packaging to inhibit the growth of spoilage and pathogenic yeasts.
 Methods: MB foams, with and without carvacrol, were produced by melt mixing and the foaming process was performed in a laboratory press. The antifungal activity of foams containing carvacrol was tested applying the disk diffusion method. Statistical analysis was done using XLStat software version 7.5.2 for Excel.&…
"L'albero Falcone" e i suoi epigoni. La propagazione vegetale della memoria antimafia
2021
Le stragi di Capaci e via D’Amelio segnano un punto di svolta nel linguaggio con cui i movimenti antimafia costruiscono la memoria pubblica della violenza mafiosa. Uno dei tratti salienti di questa svolta è la proliferazione di luoghi di memoria che ruotano intorno a figure arboree. Il capostipite di questa genealogia è l’albero Falcone, noto come punto di raccolta per le manifestazioni del 23 maggio, la giornata della legalità. Nel corso degli anni ’90, il modello memoriale costruito intorno all’albero si sviluppa e si diffonde, mentre sono sempre già frequenti le piantumazioni di alberi in memoria delle vittime della mafia. L’articolo cerca di esplicitare le forme semiotiche soggiacenti a…
Natural Compounds as Sustainable Additives for Biopolymers
2020
In the last few decades, the interest towards natural compounds, coming from a natural source and biodegradable, for biopolymers is always increasing because of a public request for the formulation of safe, eco-friendly, and sustainable materials. The main classes of natural compounds for biopolymers are: (i) naturally occurring fillers (nFil), such as nano-/micro- sized layered alumino-silicate: halloysite, bentonite, montmorillonite, hydroxyapatite, calcium carbonate, etc.; (ii) naturally occurring fibers (nFib), such as wood and vegetable fibers; (iii) naturally occurring antioxidant molecules (nAO), such as phenols, polyphenols, vitamins, and carotenoids. However, in this short review, …
Il lavoro e l'arte della ricerca: Antonino Buttitta
2018
Si tratta della ricostruzione del profilo intellettuale e scientifico di Antonino Buttitta, tra i capiscuola delle discipline demoetnoantropologiche in Italia, al quale si deve una originale declinazione dell'approccio strutturalista nell'analisi dei fatti culturali nell'ambito della semiotica della cultura.
La morte e i morti nelle società euromediterranee
2015
Il volume riflette sugli atteggiamenti storicamente assunti dall’uomo rispetto alla morte, sulle rappresentazioni e sulle ideologie correlate, sulle visioni dell’aldilà, sul culto dei defunti, sulle pratiche funerarie e sulle forme di trattamento dei defunti, sui riti connessi al trapasso e sulle cerimonie e le credenze legate al "ritorno dei morti".
