Fluorescence of Newo-Carborane Compounds with Different Fluorophores: Can it be Tuned?
2014
Two sets of o-carborane derivatives incorporating fluorene and anthracene fragments as fluorophore groups have been successfully synthesized and characterized, and their photophysical properties studied. The first set, comprising fluorene-containing carboranes 6-9, was prepared by catalyzed hydrosilylation reactions of ethynylfluorene with appropriate carboranylsilanes. The compound 1-[(9,9-dioctyl-fluorene-2-yl)ethynyl]carborane (11) was synthesized by the reaction of 9,9-dioctyl-2-ethynylfluorene and decaborane (B10H14). Furthermore, reactions of the lithium salt of 11 with 1 equivalent of 4-(chloromethyl)styrene or 9-(chloromethyl)anthracene yielded compounds 12 and 13. Members of the se…
Introduzione. Modo e senso di una ricerca comparativa sull’ascolto
2010
Esposizione del metodo adeguato ad una ricerca nell'ambito di un comparatismo (posizionato) tra mondo antico e società odierna. Tale metodo prevede: l'individuazione di un oggetto di studio capace di produrre una critica del Presente, l'esplicitazione dei propri presupposti rispetto alla società in cui si vive, la pratica di una forma di scrittura attenta a porsi, nei confronti del lettore, nel modo più aperto e meno tecnico possibile.
Effect of Stevia rebaudiana addition on bioaccessibility of bioactive compounds and antioxidant activity of beverages based on exotic fruits mixed wi…
2015
In order to determine the impact of Stevia rebaudiana (SR) addition on bioactive compounds bioaccessibility of a new developed functional beverage based on exotic fruits (mango juice, papaya juice and acai) mixed with orange juice and oat, an in vitro gastrointestinal digestion was performed. Ascorbic acid, total carotenoids, total phenolics, total anthocyanins, total antioxidant capacity and steviol glycosides were evaluated before and after a simulated gastrointestinal digestion. Salivary and gastric digestion had no substantial effect on any of the major phenolic compounds, ascorbic acid, total antioxidant capacity and steviol glycosides, whereas carotenoids and anthocyanins diminished s…
Evaluation of fermentation assisted by Lactobacillus brevis POM, and Lactobacillus plantarum (TR-7, TR-71, TR-14) on antioxidant compounds and organi…
2020
Abstract The impact of fermentation assisted by four different lactic acid bacteria (LAB) on polyphenols, carotenoids, organic acids, and antioxidant capacity of orange-juice milk based beverages was evaluated. Lactobacillus brevis POM, and Lactobacillus plantarum (TR-7, TR-71, TR-14) were used to promote the fermentation of the beverages for 72 h at 37 °C. The bacteria population increased with the elapse of fermentation period, except for beverages inoculated with L. plantarum TR-7. After fermentation period, total polyphenols, total carotenoids and total antioxidant capacity were increased compared to the control ones (non-fermented). Two phenolic acids (DL-3-phenylactic acid and 3–4-dih…
First report of brown rot and wilt of fennel caused by Phytophthora megasperma in Italy
2019
Fennel (Foeniculum vulgare Mill. var. azoricum (Mill.) Thell.) in the Apiaceae family is native to southern Europe and southwestern Asia. It is an economically important crop in Italy that produces approximately 85% of all fennel worldwide. The main producing regions are Apulia, Campania, Latium, and Calabria. During the late winter of 2004 in the Crotone Province of the Calabria Region, following heavy rains, patches of fennel plants with symptoms of brown, soft rot of the bulb-like structure formed by the thickened leaf bases, development of yellow leaves, stunting, and wilting of the entire plant were observed in fields. A homothallic Phytophthora sp. was isolated consistently from the …
A Hardware and Secure Pseudorandom Generator for Constrained Devices
2018
Hardware security for an Internet of Things or cyber physical system drives the need for ubiquitous cryptography to different sensing infrastructures in these fields. In particular, generating strong cryptographic keys on such resource-constrained device depends on a lightweight and cryptographically secure random number generator. In this research work, we have introduced a new hardware chaos-based pseudorandom number generator, which is mainly based on the deletion of an Hamilton cycle within the $N$ -cube (or on the vectorial negation), plus one single permutation. We have rigorously proven the chaotic behavior and cryptographically secure property of the whole proposal: the mid-term eff…
Una suggestione archilochea ne «La Città Morta»?
2020
This note proposes the hypothesis that in «La città morta», Act II, sc. I, d’Annunzio used a fragment of Archilochus, sent to us by Plutarch and Athenaeus.
PATRIMONIO ARCHITETTONICO E TIMELESS TIME : PER UNA PERMANENZA TEMPORANEA
2018
Com’è avvenuto per le precedenti rivoluzioni industriali, la digitalizzazione non ha sortito effetti soltanto nei processi e nei prodotti tecnologici. Tra le sue dirompenti conseguenze sulla società e sugli individui, l’emergere di una diversa concezione del Tempo sta già condizionando il campo operativo e soprattutto teoretico dell’ambiente costruito connotato da significati culturali. Inusitate forme di memoria mettono in crisi la visione tradizionale di patrimonio, fondata su una visione lineare del tempo che separa nettamente il Passato dal Futuro, lasciando al Presente un mero ruolo da passatore. Superata la presunta immutabilità, ambizione di ormai obsoleti obiettivi conservativi rigi…
Riflessioni "a margine". Il workshop "Sul margine dell'Orto Botanico di Palermo" dal punto di vista di una storica dell'arte
2020
The paper is the result of a historical research conducted during the Architecture workshop "Sul margine dell'Orto Botanico di Palermo. Spazi per Visiting Professor" ("On the edge of the Botanical Garden of Palermo. Spaces for Visiting Professor"), organized from 24 to 27 September 2018 by the Professors of the University of Palermo Andrea Sciascia, Giuseppe Di Benedetto, Giuseppe Marsala and Antonino Margagliotta and included in the teaching activities of the PhD in Architecture, Arts and Planning. It consists of a descriptive part of the Manifesta12 interventions – the prestigious nomadic Biennial of contemporary art whose last edition took place in Palermo – at the Botanical Garden. This…
Il progetto didattico tra storia e modernità
2017
Il progetto didattico del Laboratorio V di Progettazione Architettonica, si configura come un percorso conoscitivo dove far confluire la complessità delle problematiche atte - attraverso il progetto - a stimolare la comprensione dei luoghi, delle loro modificazioni e a testimoniare la contemporaneità. La città contemporanea, infatti, è frutto di una coesistenza di elementi spesso prodotti di distruzioni belliche e politiche di cui le rovine sono le testimonianze. Il progetto contemporaneo deve essere capace di disvelare tali luoghi e nello stesso tempo avere la capacità di ricomporre le singole parti attraverso una nuova riconfigurazione urbana. The educational project of the V Laboratory o…
