Les discours de Libanios (discours 33-64) et la topographie d’Antioche
2012
The work is preparatory to elaborating a Libanius' lexicon attentive to the different nuances that seemingly common words can take on in a specific context such as that of his speech.
La cimera con cabeza de lobo del “Vaso de las cabezotas”, Lliria (Edeta): una posible interpretación
2015
En este artículo pretendemos analizar el sentido simbólico y ritual que pudo existir detrás de las cimeras que imitaban animales, como el lobo, y que embellecían los cascos de los guerreros en la Antigüedad. Para ello utilizaremos como hilo conductor la imagen del guerrero ibérico presente en un vaso cerámico encontrado en el departamento 95 del yacimiento ibérico de Edeta, situado en el Cerro de San Miguel de Lliria, conocido como el Vaso de las cabezotas. n this paper we would like to analyse the symbolic meaning and the ritual that could be behind plumes and chimeras imitating animals as the wolf and embellished helmets of the warriors in Antiquity. We will use as a guideline the Iberian…
Il packaging come icona culturale? Processi di significazione e meccanismi intertestuali
2020
Questo contributo si interroga sul modo in cui alcune confezioni dei prodotti possano assurgere a icone culturali in grado di condensare, e al tempo stesso trascendere e rilanciare, ampi significati di tipo socioculturale. I packaging di alcuni brand mondiali, gia da tempo, sono diventati non solo segno inconfondibile del brand di appartenenza (si pensi alla contour di Coca-Cola o al barattolo di Nutella), ma anche oggetti in grado di comunicare molto altro, che finiscono per sganciarsi dal marchio e contribuiscono a far circolare valori di consumo, abitudini di un’epoca, usi collettivi di una certa cultura. Attraverso l’analisi di alcuni casi studio, indagheremo proprio quali sono i proces…
High-Sensitivity Whispering Gallery Mode Humidity Sensor Based on Glycerol Microdroplet Volumetric Expansion
2021
We demonstrate a highly sensitive whispering gallery mode (WGM) relative humidity (RH) sensor based on a glycerol microdroplet. WGMs were excited using a 760 nm tunable semiconductor laser. We used free space coupling, which is effective when using a liquid resonator. A detailed analysis of different parameters influencing the sensor’s characteristics (sensitivity, hysteresis, resolution, stability, and temperature) is presented. The sensitivity of the sensor is one of the highest reported (2.85 nm/% RH in the range 50–70% RH with the resolution 1 × 10−4% RH). This type of humidity sensor has several advantages, such as high sensitivity, extended lifetime, good repeatability, and low cost, …
Global Communication with Icons in Environmental Contexts
2016
Icons are small signs with fixed meanings. Icons are usually context specific. For example in the context of a hotel, the client can often find icons in hotel room books and safety guides. Scandic Hotel chain, for example, currently provides the manual for its safety system in 14 languages. There are at least two major shortcomings of this system: (1) in emergency or panic situations, it is very difficult to find your own language from the leaflet, and (2) there are no Asian languages. There is an obvious need for a global icon-based hotel safety language. In our paper, we introduce an icon-based model, language and mobile application for hotel safety. peerReviewed
Synthesis of nanostructured protein–mineral-microcapsules by sonication
2022
We propose a simple and eco-friendly method for the formation of composite protein–mineral-microcapsules induced by ultrasound treatment. Protein- and nanoparticle-stabilized oil-in-water (O/W) emulsions loaded with different oils are prepared using high-intensity ultrasound. The formation of thin composite mineral proteinaceous shells is realized with various types of nanoparticles, which are pre-modified with Bovine Serum Albumin (BSA) and subsequently characterized by EDX, TGA, zeta potential measurements and Raman spectroscopy. Cryo-SEM and EDX mapping visualizations show the homogeneous distribution of the densely packed nanoparticles in the capsule shell. In contrast to the results re…
Rigenerazione dell’area dell’ex fabbrica tessile Gulì a Palermo
2018
L’attività industriale palermitana, pur avendo vissuto un periodo fiorente piuttosto breve, ha lasciato tracce ben riconoscibili e identificabili all’interno del tessuto urbano, con manufatti architettonici di notevole importanza per qualità di progetto e dimensioni. L’ex fabbrica tessile Gulì è un complesso interessante sia dal punto di vista architettonico sia per la sua localizzazione urbanistica, molto prossima a poli di rilevante interesse culturale. Lo studio, condotto presso il Dipartimento di Architettura dell’Ateneo di Palermo, propone un intervento di rigenerazione che coinvolge non solo i manufatti edilizi presenti ma l’intera area e la sua trasformazione in un nuovo centro di qu…
Diversity in warning coloration: selective paradox or the norm?
2019
Aposematic theory has historically predicted that predators should select for warning signals to converge on a single form, as a result of frequency-dependent learning. However, widespread variation in warning signals is observed across closely related species, populations and, most problematically for evolutionary biologists, among individuals in the same population. Recent research has yielded an increased awareness of this diversity, challenging the paradigm of signal monomorphy in aposematic animals. Here we provide a comprehensive synthesis of these disparate lines of investigation, identifying within them three broad classes of explanation for variation in aposematic warning signals: …
La voce allo specchio
2012
En partant de l'hypothèse de Rizzolatti et collègues (1998, 2007) d'un isomorphisme originaire entre phonétique et sémantique, l'article analyse le rapport entre les différences phonologiques et les différences sémantiques dans quatre ensembles de mots monosyllabiques italiens (monophonèmes, pronoms, verbes et adverbes) et montre que les signifiants tendent à s'opposer entre eux par le biais des traits phonologiques distinctifs comme les signifiés s'opposent par le biais de traits morphologiques et sémantiques. Par exemple, le premières personnes tendent à être relativement plus postérieures et graves, les deuxièmes, antérieures et aiguës et les troisièmes centrales et ouvertes. En outre, d…
Enhancement of hepatitis C virus RNA replication by cell culture-adaptive mutations.
2001
ABSTRACT Studies of the Hepatitis C virus (HCV) replication cycle have been made possible with the development of subgenomic selectable RNAs that replicate autonomously in cultured cells. In these replicons the region encoding the HCV structural proteins was replaced by the neomycin phosphotransferase gene, allowing the selection of transfected cells that support high-level replication of these RNAs. Subsequent analyses revealed that, within selected cells, HCV RNAs had acquired adaptive mutations that increased the efficiency of colony formation by an unknown mechanism. Using a panel of replicons that differed in their degrees of cell culture adaptation, in this study we show that adaptive…
