Alternative energy scenarios for small islands: A case study from Salina Island (Aeolian Islands, Southern Italy)

2012

Abstract The Aeolian archipelago is made up of seven main islands situated in the Tyrrhenian sea (Sicily Italy). They represent a suitable scenario for the development of a sustainable energy production system, that could easily be reproduced on other Mediterranean Islands. The fact that these islands depend on the mainland for energy supplies and the high cost of bringing fuel in tanker boats are factors that should strongly encourage the use of renewable energy source technologies. Taking into account the European Commission guidelines, this paper sets out to evaluate potential energy production using photovoltaic and small scale wind power, in order to verify their contribution to overal…

A new species within the Centaurea busambarensis complex (Asteraceae, Cardueae) from Sicily

2022

The Centaurea busambarensis group is made up by eight species endemic to Sicily. We statistically evaluated a population found on the Nebrodi Mountain (NE Sicily) to verify if the observed morphological differences with the already known taxa justified the description of a new one. It resulted in being sufficiently distinct to deserve recognition at the species level. Centaurea valdemonensis, a new species endemic to Sicily is described and illustrated here. It is confined to the Nebrodi Mountains (NE Sicily). The distinction of this taxon from the others belonging to the C. busambarensis complex has been supported with the aid of statistical analyses on morphological characters. The differ…

Cover crops effectiveness for soil erosion control in Sicilian vineyard

2009

In vineyards, which are very common in Mediterranean area, cover crops are becoming increasingly used to reduce soil erosion. Cover crops reduce runoff by increasing infiltration and increasing roughness and then reducing the ovelandflow velocity. The aim of the present study was to quantify soil and water losses under different soil managements systems on vineyards. The study site was a Sauvignon blanc winegrape vineyard located in Southwestern Sicily. Vineyards were managed both traditionally (conventional tillage) and alternative management using cover crops: 1) Vicia faba ; 2) Vicia faba and Vicia sativa; 3) Trifolium subterraneum, Lolium perenne, Festuca rubra; 4)Trifolium subterraneum…

Building the space: vaults’ geometry and stereotomy. Materials and architectural technologies in the Mediterranean area

2018

Costruire una volta ha sempre nei secoli rappresentato un’arte pratica che si nutriva del contributo di chi operava in cantiere: indispensabile risultava la tecnica, il sapiente taglio della pietra e l’opportuna collocazione della stessa nel gioco statico dell’organismo murario. Un sapere tecnico, questo, che combinava l’estetica con la organizzazione strutturale della fabbrica costruenda; l’esperienza pratica aveva dettato a muratori e scalpellini i precetti in merito ai differenti compiti organizzativi e alle relative gerarchie degli esecutori dell’opera edilizia, all’attrezzature e alle macchine da cantiere, agli utensili e alle lavorazioni da usare, incentivando una spiccata attitudine …
