CONSERVATION STATUS ASSESSMENT OF THE ENDEMIC HIERACIUM S. STR. (ASTERACEAE) OCCURRING IN SICILY

2022

The current status of the majority of apomictic taxa, and therefore their priorities for conservation, are poorly known, and consequently, they are neglected by conservationists. In Sicily 8 species and 4 subspecies of Hieracium s. str. occurs. Eleven taxa are endemic to the area, one has a wider distribution. These taxa were not evaluated within the recent project “Red List assessment of plants and fungi in Italy” because collectively considered with insufficient and unreliable distribution data. The global conservation status of the endemic Hieracium s. str. taxa occurring in Sicily was assessed here using the IUCN categories and criteria, on the basis of the data collected during field s…

The cork oak in the Mountains of Palermo (Italy): ecological insights from the south-eastern edge of its distribution range

2020

Abstract: The uneven presence of the cork oak (Quercus suber L.) within its distribution range is not only determined by its climatic requirements but also by specific edaphic needs. Although most of the natural populations thrive in acidic soils deriving from metamorphic or volcanic rock outcrops, some cork oak populations are found growing in soils deriving from calcareous bedrock, which are considered less suitable. We carried out a multidisciplinary investigation at the south eastern edge of the Q. suber distribution range (Mountains of Palermo, NW Sicily), including soil, floristic, and vegetation surveys, aimed at: (i) assessing the native or introduced origin of some peculiar cork oa…

Architetture per l'energia. Fuoco (e ceneri) di una rivoluzione

2017

Se riconosciamo negli edifici industriali le radici dell'architettura moderna, la mutazione di significato a cui le architetture per l'energie vanno incontro, vale a dire quelle animate dalla fata elettricità all'inizio del XX secolo, può definire l'attuale concetto di fuoco. Considerata la rivoluzione del Novecento, la scoperta e l'applicazione dell'energia ha innescato un processo che non si è mai arrestato e che ha reso l'energia la vera chiave d'accesso alla contemporaneità. Oltre l'obsolescenza e l'uso dei combustibili tradizionali, l'elettricità è energia potenziale, ancora contenuta negli oggetti e capace di produrre nuovi valori; energia vera e propria, che consente agli apparecchi …

Arcangelo Michele Migliarini (1779-1865): formazione artistica, divagazioni critiche e rapporti con il collezionismo di un antiquario ottocentesco

2006

L'auteur étudie la figure d'Arcangelo Michele Migliarini, peintre et archéologue, dont le parcours et la pensée sont emblématiques de la situation artistique et culturelle de Rome à la fin du 18e s. et au début du 19e siècle. Dans un premier temps, il reconstruit et contextualise les étapes de sa formation artistique et intellectuelle à Rome, puis il retrace son parcours et la façon dont il a réussi à s'imposer dans des institutions telles que l'Académie des beaux-arts ou la Galerie des Offices de Florence enfin il analyse les liens de Migliarini avec le marché de l'art et le collectionnisme. Il insiste sur le rôle de Migliarini dans le développement du classicisme au début du 19e siècle.

Nino Rota / 2. Indimenticabili sinfonie

2009

L'articolo fa parte di una serie di sei ritratti di compositori italiani del Novecento realizzati per la rivista della SIAE "Viva Verdi" e pubblicati fra il 2009 e il 2010. In particolare, viene tracciato un profilo biografico del compositore, dall'esordio come "bambino prodigio" sino agli anni Settanta, con particolare riferimento alla produzione sinfonica e agli ambiti della musica sacra e del teatro musicale

Innovazione e resilienza nella città intelligente. Pratiche fiorentine al tempo della pandemia

2021

La pandemia ha dato l’opportunità ad alcune città di dimostrare il grado di competitività raggiunto e di divenire un modello di riferimento. In questi contesti non ha prevalso l’immobilismo o la sterile attesa, ma una fervente attività propositiva e creativa. Il presente contributo si propone di approfondire solo una delle esperienze di creatività e di azione all’interno di una città certamente smart, Firenze. Il caso della Galleria degli Uffizi dimostra la capacità dei contesti ad elevato livello tecnologico e di competenze di superare con brillantezza le situazioni critiche che, nella loro diversificata configurazione, possono presentarsi. The pandemic has given some cities the opportunit…

Bioadhesive monolayer film for the in vitro transdermal delivery of sumatriptan

2006

The work presented here aims to develop a bioadhesive monolayer film containing sumatriptan as adjuvant for the treatment of headache pain in a severe migraine attack. Permeation experiments were performed from the films prepared and from the respective solution, to evaluate the relevant permeation parameters. The effect of the penetration enhancers Transcutol, 2-pyrrolidone, and polyethylene glycol 600 was evaluated. The results obtained show that Transcutol and 2-pyrrolidone decreased sumatriptan permeation from solution, whereas a modest increase was produced by polyethylene glycol 600. The enhancers produced the same effects when they were included in the film. Compared to solution, the…

A methodology for fire data analysis based on pattern recognition towards the disaster management

2015

The aim of this paper is to investigate a proposed strategy for fire disaster analysis that is implemented based on pattern recognition technique in order to achieve a methodology for disaster management. Since the fire hazard has severe effects onto human and properties, it is essential to predict and possibly prevent it. Almost every fire produces some issues, such as heat, smoke, gas, and flame, which are sensible and measurable via devices or detection systems. The fire behavior is relevant to these issues. In this research, temperature, heat radiation, and visibility (smoke) data of fire that have been obtained from Fire Dynamics Simulator (FDS) are used for analysis. The location of t…

The digital outcry: What incites participation behavior in an online firestorm?

2017

Brands, celebrities, or politicians are increasingly facing enormous online outrages in response to moral misconducts. These online firestorms are characterized by high message volume, indignant tonality, and negative opinion climate. Based on the concept of moral panics, this article analyzes why people join online firestorms. We argue that participation behavior is driven by a moral compass and a desire for social recognition. Results of an experiment and a content analysis of user comments show that a higher number of participants decreases users’ willingness to participate but fosters compliance with the prevalent opinion and tonality of the comments. We also observe that a higher mora…
