Propaganda grafico-persuasiva. Segni, forme, sguardi
2019
A partire da una ricognizione iconografica di alcune delle trasformazioni sociali che nella storia del XX secolo hanno intravisto nel poster un mezzo di comunicazione e nell’immagine un dispositivo per l’informazione capillare, il saggio mira ad approfondire le forme assunte dalle ideologie storiche nei poster di propaganda, le metafore grafiche adottate per divulgare il messaggio e le tecniche persuasive per diffonderne i valori. Non si tratta di una classificazione iconografica strutturata per artista o per periodo storico, ma di un’analisi sull’individuazione di un comune linguaggio per la rappresentazione delle ideologie politiche che in particolari momenti storici si sono intrecciate c…
Can histographic analysis of apparent diffusion coefficient help discriminate between benign and malignant nodes in head and neck squamous cell carci…
2011
Objective: To investigate histographic analysis of apparent diffusion coefficient (ADC) measurements as discriminators of benign from malignant lymph nodes in patients with head and neck (H&N) squamous cell carcinoma (SCC) Materials and Methods: Seventeen patients with H&N SCC staged for nodal disease using anatomical MRI, contrast enhanced CT and ultrasound ± fine needle aspiration gave informed consent for additional MR diffusion weighted imaging (DWI). Axial DWI was performed by short tau inversion recovery (STIR) echo planar imaging and trace weighted images obtained b 0, 50, 100, 300, 600 and 1000. Image analysis was conducted using Jim 5.0. Nodal disease and contralateral benign nodal…
Mamluk Reproductions: Survey and Analysis of Tombs in the Cemetery of Sant’Orsola in Palermo.
2016
The contribution presents a study of various funeral chapels found in the cemetery of Sant'Orsola in Palermo. Realised during the 19th and 20th centuries, they van be taken as examples of Sicilian Orientalism. An original reading of the Rutelli Chapel, starting from the unpublished survey of its current state, provides an understanding of its geometry and morphology. The survey was conducted using the techniques of Structure from Motion. The Rutelli Chapel offers a very interesting example of architecture that demonstrates several similarities with some Mamluk mausoleums in Cairo.
Evolutionary history of treecreeper vocalisations (Aves: Certhia)☆
2008
AbstractSince the vocalisations of passerine birds are in general a good means to separate taxa when external morphological differences are few, song and call recordings of 33 treecreeper (Certhia) taxa were sonagraphed and their parameters analysed. The vocalisations show low intra-individual and intra-population variation. Phylogenetic evolutionary units at the population level were delimited by time, frequency and syntax parameters by means of principal-component and discriminant analyses. Traits of territorial song were traced on a phylogenetic tree based on cytochrome b sequences, and a mean acoustic character difference was calculated. All presently recognised nine species could be di…
A 3D REWORKING OF THE URBAN TRANSFORMATIONS OF PALERMO IN RECENT HISTORY FOR A HYPOTHESIS OF A "CITY MUSEUM" BASED ON DIGITAL VISUALIZATIONS
2021
Abstract. The objective that drives this research is given by a multitude of information which, in addition to the contribution of technology, allows us to study, analyze, verify and remodel the sites, monuments and evolutions of the city through graphic processes of perspective restitution that start from the analysis of historical photos. The drawing methods, the digital graphic rendering and through the aid of geometric techniques, contribute to the reconstruction of projects and architectures that are now lost, this is possible thanks to the methods of perspective, axonometry and three-dimensional restitution.This remarkable photographic heritage belonging to Palermo, but also to any ot…
Sea-level changes during the last 41,000 years in the outer shelf of the southern Tyrrhenian Sea: Evidence from benthic foraminifera and seismostrati…
2011
Abstract An integrated high resolution study based both on a seismostratigraphic approach and on a sedimentary core (VIB 10), collected in the outer shelf (127 m depth) from the southern Tyrrhenian Sea (Gulf of Termini, Sicily), provides new data about climatic, eustatic and paleoenvironmental changes during the last ∼41,000 years. The results based on the interpretation of a seismic profile, on benthic foraminifera assemblages and on δ18O records, allowed recognition of two drastic sea-level falls during the Last Glacial Maximum (LGM) and the Younger Dryas (YD). The short deglacial event, between LGM and YD, known as Bolling/Allerod, played an important role in the sea-level rise that prod…
A virtual reconfiguration of two destroyed neighborhoods in the Old Town of Palermo
2018
The proposed contribution deals with the topic of virtual three-dimensional reconstructions on an urban scale. The choice was oriented on significant samples of city portions that over the centuries have undergone substantial transformations or distortions: the aim is to reconstruct their history backwards, starting from the current survey and using the tools of virtual representation to reconfigure the forms of the past and tell their events. From here comes the idea to create, for pieces, a hypertextual study of the urban image of Palermo: the theme of the transformation of the city, of change and of complexity, opens up differentiated research paths. The hypertext choice was almost obvio…
Proportions in Salvatore Caronia Roberti Between Theory and Practice
2022
AbstractIn 1949 Salvatore Caronia Roberti published the volume Introduzione allo studio della composizione architettonica. It is a compendium of his own studies and research came together in his architecture, testifying to the close interweaving of theory and practice. Caronia Roberti was a student of Ernesto Basile, one of the leading exponents of Art Nouveau, a style in which proportions played a marginal place. He later broke away from the Master’s school to attempt a new path in which geometry and proportion constitute the core of his theoretical research. This study aims to highlights the organic nature of Caronia Roberti’s thought, between architectural history and representation, by …
Visual Perception and Graphic Analysis. The Pattern of Inlays in the Cathedral of Palermo
2017
The Cathedral of Palermo is one of the monuments belonging to the Arab-Norman Itinerary, declared a UNESCO World Heritage site in 2015. This text uses geometric analysis to describe some of the inlaid circular designs from the eastern façade, the corner towers and the apses. The cataloguing of the two-tone geometric motifs also reveals aspects that can be linked back to the laws of visual perception. Hence, the text investigates these aspects based on a new reading. In fact, decomposing these elements based on the experience of their perception also facilitates the recognition of elementary figures. The attempt made in this brief text intends to induce a new perceptive awareness resulting f…
La placa grabada de Balma Guilanyà (Prepirineo de Lleida) y las manifestaciones artísticas del Mesolítico de la Península Ibérica
2011
A carved rock with geometric and/or abstract signs discovered at the Balma Guilanyà site has made possible the analysis of the artistic patterns developed after the end of the Upper Palaeolithic in the Iberian Mediterranean region. Archaeo-stratigraphic, chronometric and chrono-cultural attributes link this finding to the Mesolithic, probably during the tenth millennium cal BP. Graphic analysis and the comparison with different kinds of representations from this same area allows the evaluation of the problematic that surrounds the characterization of West Mediterranean Mesolithic art.
