INNOVAZIONE DEI MATERIALI NATURALI: TERRA E NANOTUBI DI ARGILLA PER UNA SFIDA SOSTENIBILE
2019
All’interno del dibattito culturale che vede la questione ambientale come prioritaria e con riferimento a studi e ricerche che negli ultimi anni hanno promosso materiali compositi a base di terra cruda, gli Autori, consapevoli della necessità che il rapporto fra Progetto e Materia debba assumere una nuova centralità supportato dalle specificità della Tecnologia dell’Architettura, illustrano le risultanze di una sperimentazione che ha l’obiettivo di migliorare le prestazioni della terra cruda con l’apporto delle nanotecnologie, sviluppando un ‘nuovo materiale’ con una ridotta embodied energy e una ridotta quantità di emissioni di CO2 in atmosfera.
La cultura ci salverà? Processi di touristification a base culturale nel centro storico di Palermo
2023
Negli ultimi tre decenni la cultura ha avuto un ruolo chiave nella costruzione delle politiche urbane, divenendo uno strumento decisivo nella definizione delle strategie di sviluppo economico e nell’accesso alla competizione globale che caratterizzano l’attuale regime di neoliberismo urbano (Miles e Paddison 2005). Anche nel sud Europa la cosiddetta rigenerazione a base culturale ha rappresentato e continua ancora oggi a rappresentare una vera e propria ortodossia urbana, che trova nel turismo tanto una ragione di esistenza quanto un campo di attuazione. In particolare, negli ultimi anni i centri storici di molte città sudeuropee sono stati oggetto di trasformazioni profonde in cui pratiche…
Performance improvement of a Savonius water rotor with novel blade shapes
2021
Abstract Savonius water rotor is a prominent drag based turbine able to extract energy available in flowing water with low velocity like river streams, tidal currents or other man made water canals. However, in view of its low performance, an enhanced design of the rotor blades is necessary to better its efficiency. Therefore, the present study aims to improve the efficiency of Savonius rotor by changing the blade design. Different blade shapes were investigated numerically using computational fluid dynamics (CFD). Using conventional design, the peak power coefficient was found to be 0.166 at tip-speed ratio of 0.78. However, the peak power coefficient reaches 0.184 using the optimal blade …

Le paysage comme représentation spaciale : le paysage viticole comme symbole des indications de provenance des vins des régions Vale dos Vinhedos, Pi…
2011
The theme of this thesis is the landscape in its specificity vineyard analyzed as a spatial representation in the building process of the geographical area of viticulture growing and the use of image of vineyard landscape as spatial landscape of the wine of the regions of Geographical Indication (GI’s) Vale dos Vinhedos, Pinto Bandeira and Monte Belo, Brazil. The objective was to explain the use of vineyard landscape as spatial representation and the images of vineyard landscape as spatial symbol for the wines of GI’s. The theoretical sources to analyze are related to the Critical geography and with the Cultural geography. The organization of the geographic area of the regions of GI’s comes…
L’usage des trachytes de la chaîne des Puys depuis deux millénaires
2021
The very recent work carried out within the framework of a Collective Research Project (PCR-Trachytes) supported by the Auvergne-Rhône-Alpes Regional Directorate of Cultural Affairs has completely renewed our knowledge of the use of trachytic lavas from the chaîne des Puys over the last two millennia. A complete petrographic identity sheet has been established for each of these trachytes. This database showed that each trachytic volcano was made up of a different lava from those of its neighbours, except for Cliersou and Aumône which have the same lava. Moreover, for the Puy de Dôme and the Cratère Kilian, it was shown that they were each made up of two different lavas. Thus, the fine chara…

Diffusion régionale du silex crétacé des minières de Saint-Gond (Marne, France) au Néolithique récent et final
2018
International audience; La région des Marais de Saint-Gond (Marne) comporte un très grand nombre de sites néolithiques. Elle est surtout connue pour ses nombreuses sépultures collectives en hypogées et en allées couvertes. Des ateliers de taille et des habitats y ont également été détectés. Tous ces sites ont fourni des quantités de silex taillés. L’origine de ces silex et le contexte géologique de la région n’avaient pas encore fait l’objet d’une étude détaillée. Depuis 2012 les prospections ont permis de localiser 17 minières et plusieurs dizaines d’affleurements de bancs de silex. Ces données montrent que le silex est très abondant dans la région et qu’il a été intensément exploité au Né…
Raw material procurement and selection in Southeast Iberia’s early metallurgy
2020
The role of metallurgy in the Copper Age communities of the Iberian Southeast is a recurrent question of archaeological research in western Europe. Based on lead isotope and trace element analyses of archaeometallurgical remains, this paper addresses the territorial organisation of metallurgical production during the Copper Age (3100-2200 cal BC) in the Vera Basin (Almería, Spain), the region with the earliest metallurgical evidence in western Europe. This paper comprises the study of materials from the three main settlements with metallurgical activity in the area (Las Pilas, Santa Bárbara and Almizaraque), as well as some metal objects from these and other sites (La Encantada I, Loma…
