CONTRIBUTO ALLE CONOSCENZE LICHENOLOGICHE DELLA VALLE D’AOSTA: FLORULA DELLA CONCA DI FLASSIN (VALLE DEL GRAN SAN BERNARDO)
2008
Complessivamente sono stati censiti 75 taxa che rappresentano il primo ritrovamento per il sito indagato. Nel corso dell’escursione sono state raccolte 6 specie (Caloplaca inconnexa v. inconnexa, Lecanora rupicola ssp. subplanata, Lecanora subcarpinea, Protoparmeliopsis muralis v. dubyi, Rhizocarpon macrosporum, Tetramelas triphragmioides) di nuova segnalazione per la Valle d’Aosta. Solo quattro entità tra quelle censite risultano già note per la Valle del Gran San Bernardo: Cladonia gracilis, Peltigera didactyla, Rhizocarpon geographicum e R. lecanorinum vennero segnalate in prossimità della vetta del Mont Mort (Vaccari, 1914). Attualmente gli esemplari sono conservati presso l’Erbario del…
Eustatic and oceanographic control on sedimentary evolution of middle-late Quaternary shelf margin-to-upper slope deposits on the Egadi Islands offsh…
2016
During the past decades a number of sequence stratigraphy studies illustrated how, during Quaternary, interaction between sea level changes and sediment supply controlled the depositional evolution along continental margins, giving a cyclic signature to the sedimentary infilling. However, as both deposition and erosion are processes ultimately controlled by balance between environmental energy and sedimentary influx, also the oceanographic regime takes part in controlling the sedimentary growth along the continental margin. This is exactly what occurs on physiographic settings as islands offshore areas, where bottom currents can be very energetic. In the western Sicily offshore, southwards …
Wildlife park of Etna
2013
Mount Etna is located west of the east coast of Sicily, within the territory of the province of Catania and is crossed by 15’ meridian east, which it takes its name. It’s occupies an area of 1570 . It’s dimensions place it among the largest in the world and, from the geological standpoint, the highest of the European continent.
LARGE LANDSLIDES AND NEOTECTONICS: A CASE STUDY IN WESTERN SICILY
2009
The study area is located in the western sector of the Sicanian Mounts where the superimposition, consequence of the Miocene and Lower Pliocene tectonic transpressive phases, of different geologic bodies, having vergence to the southern quadrants, can be observed. In this area, the neo-autochthonous deposits are given by marly-clayey sediments of middle-upper Pliocene, pertaining to the “Marnoso-arenacea” Formation of the Belice Valley, and by Pleistocene calcarenites. The recent extensional tectonic crisis (neotectonics) have further dissected and dismembered the original structural edifice, involving also the Pleistocene calcarenites, which show tectonic displacements mainly NE – SW orien…
Petrology of some amphibole-bearing volcanics of the pre-Ellittico period (102-80 ka), Mt. Etna
2006
We present here petrological and geochemical data on volcanics cropping out in southern and northeastern walls of the Valle del Bove (Mt. Etna), belonging to the Rocche, Serra Giannicola Grande and Canalone della Montagnola Units. These units constitute the remnants of several volcanoes that were active in the time span 102-80 ka, i.e. before the growth of the Ellittico-Mongibello strato-volcano. Their products, range in composition from hawaiites to benmoreites. Amphibole (kaersutite) is present as phenocryst in all the studied rocks, and commonly shows breakdown coronas of rhönite ± clinopyroxene and plagioclase formed during magma ascent. Nevertheless, in mafic rocks, amphibole occurs as…
Unsaturated sand in the stability of the cuesta of the Temple of Hera (Agrigento)
2013
In the Valle dei Templi in Agrigento seven Doric temples stand lengthwise the crest of a rigid calcarenite cuesta over a layer of carbonate sand which lies along a thick stratum of clays. The environment is highly prone to landslides since topplings of calcarenite blocks often occur. The rock slopes are moving back and the slope edge draw near to the foundation of the Temple of Hera Lacinia contributing to increase their perilous condition. To assess the role of unsaturated sands in the instability processes, after the compositional and textural analysis of the material, direct shear tests and oedometer tests have been carried out on sand samples initially at the natural state, with low or …
Linee guida per un protocollo all’accessibilità della città storica di Palermo
2021
Il progetto I-Access nasce dalla precisa volontà di sperimentare un nuovo modello di approccio, utilizzando l’accessibilità come chiave interpretativa e progettuale innovativa per gli interventi nei centri storici, così come oggi si presentano a partire dai nuovi sce- nari sociali e culturali configuratisi a seguito della seconda guerra mondiale, e poi strut- turati in seguito alla ricostruzione post-bellica e al progressivo riconoscimento internazionale quale patrimonio culturale dell’umanità siglato per l’intero centro storico di La Valletta nel 1980 e per l’itinerario arabo-normanno per la città di Palermo nel 2015. Tali riconoscimenti diventano un rinnovato punto di partenza per mantene…
Dossier degli eventi
2021
Il Dossier raccoglie attraverso le immagini e le didascalie gli eventi che hanno accompagnato il progetto Interreg Italia-Malta I-Access. ll progetto I-Access ha sviluppato soluzioni innovative nei centri storici delle città di Palermo e La Valletta culturale e fisica per il miglioramento dell’accessibilità culturale e fisica del patrimonio, volano di integrazione e sviluppo per le società dei due Paesi, chiamati ad affrontare sfide comuni. Il progetto interdisciplinare grazie allo scambio di competenze transfrontaliere, al Partenariato delle due Municipalità e della Soprintendenza della Regione Sicilia, ha definito nuove linee metodologiche, sviluppato nuovi modelli, sperimentato nuovi…
Campus Asia “Cinema Paradise” 2021. “Above the clouds”: Un progetto temporaneo per la Valle di Bolognetta
2021
In the frame of the international winter school organized by Campus Asia, the Valley of Bolognetta has been chosen by the LabCity Architecture group as the official site for an architectural competition. On the 30th anniversary of the Academy Award to Maestro Giuseppe Tornatore, Campus Asia promoted “Cinema Paradise” as main theme to design an architectural project that is envisioned as strictly connected to the people and to the environment. The project “Above the cloud”, presented by LabCity Architecture Team from the University of Palermo, joins nature and architecture through the design of a performative event.
La città e gli alberi. Progetti di Gianni Pirrone per Palermo e Gibellina Nuova
2022
In the wake of the historical tradition of landscape architecture, the architect Gianni Pirrone (Palermo, 1924-2004) understood the need to look at urban greenery as a figure and not as a background, or frame of buildings and neighbourhoods. Pirrone consigns to an imminent future - a time that escapes our eyes today - the need for a new relationship between ecological reserves, gardens, residual areas and the city. The projects for the Botanical Garden and the Oreto Valley in Palermo and for the civic center of Gibellina Nuova solicit for a current reflection, making an interesting starting hypothesis. The vegetation, the colours, the water, the silence can take over and extend into an unpr…
