Low cost survey techniques aimed to the Cultural Heritage conservation.

2017

Thanks to SfM (Image Based Modeling) survey techniques, is possible to realize 3D models of every object, in a very short time and with limited economical and training resources, today. These semi-automated SfM software allow users to simply upload photos and follow a mediated workflow, without any complex inner workings of SfM and this can be especially advantageous to users in non-technical fields or to those with limited resources. Every year there is an international Event, #digitalinvasion, that involves the Italian museums and that reckons on to allow to take pictures and video to the whole museum collections. This event is present in Palermo since 2014 and the Engineering first year …

Shoreline Evolution and Environmental Changes at the NW Area of the Gulf of Gela (Sicily, Italy)

2021

Coastal areas are among the most biologically productive, dynamic and valued ecosystems on Earth. They are subject to changes that greatly vary in scale, time and duration and to additional pressures resulting from anthropogenic activities. The aim of this work was to investigate the shoreline evolution and the main environmental changes of the coastal stretch between the towns of Licata and Gela (in the Gulf of Gela, Sicily, Italy). The methodology used in this work included the analysis of: (i) shoreline changes over the long- and medium-term periods (1955–2019 and 1989–2019, respectively), (ii) dune system fragmentation and (iii) the impact of coastal structures (harbours and breakwaters…

Tutela e restauri in Sicilia e in Calabria nella prima metà del Novecento : istituzioni, protagonisti e interventi

2015

Il volume Tutela e restauri in Sicilia e in Calabria nella prima metà del Novecento Istituzioni, protagonisti e interventi, raccoglie gli esiti di uno studio finanziata con il Fondo Finalizzato alla Ricerca dell’Università degli Studi di Palermo, dell’anno 2012-2013. Operatori e monumenti sono i protagonisti di questa storia variegata che ha come comune territorio quello che era stato della Magna Grecia, con le sue stratificazioni medievali. Alla ricerca hanno partecipato vari studiosi, anche appartenenti a diverse istituzioni sia universitarie che per la tutela e la conservazione del patrimonio storico architettonico della Sicilia e della Calabria. La metodica dello studio è stata indirizz…

A rediscovered sign of the medieval identity in the ancient town of Palermo: a tower house in the Kalsa and its historical stratifications

2020

A building supposedly belonged to the House of Chiaramonte (or Chiaromonte) in Sicily was kept for several centuries inside the volume of a larger building in the Kalsa district of Islamic foundation, in Palermo. The sudden detachment of the plaster and some stone elements at the beginning of the 80s of the 20th century made it possible to identify the traces of the façade of a fourteenth-century tower-house, characterized by a series of four windows with pointed arched elements and archivolts with rings of broken sticks, surmounted by a weft of interwoven bands of two-tone stone elements. The contribution retraces the study activities to identify the architectural cultures that coexist in …

Restauri in Sicilia: gli interventi sui beni architettonici danneggiati dal terremoto del 1968 nella Valle del Belice

2020

Questo contributo mira ad integrare lo scenario culturale delle eterogenee esperienze incluse nella sessione “Protezione, pratica, codici e norme” del secondo Convegno Internazionale della SIRA Società Italiana per il Restauro dell’Architettura. L’articolato ventaglio dei casi studio, che spazia dal tema della tutela dei siti d’interesse ambientale alle normative settoriali in Italia e Francia, ed include le questioni tecniche e metodologiche riguardanti il cantiere di restauro, è completato dall’esperienza del restauro dei beni architettonici nei centri urbani danneggiati dal terremoto che interessa la valle del Belice in Sicilia nel 1968. Dopo aver inquadrato i luoghi danneggiati dal viol…

HISTORIC CITIES AND INNER AREAS IN SICILY The point of view of the Restoration

2022

The discipline of restoration has long established a cultural background on the subject of historic cities as a heritage area to be safeguarded, beginning with the Amsterdam Declaration (1975), which introduced the fundamental concept of «integrated conservation». The purpose of this contribution is to emphasize the importance of raising an awareness and care for heritage as a community identity card and not just a reason for tourist offer. The territory and cultural heritage thus become a pedagogical challenge in defining a model of heritage enjoyment, for the promotion of local contexts and in the constitution of learning communities in which restoration likewise participates.

Co-digestion of grass silage and cow manure in a CSTR by re-circulation of alkali treated solids of the digestate.

2008

Three laboratory, continuously stirred tank reactors (CSTRs) co-digesting grass silage and cow manure (forming 30% and 70% of substrate volatile solids (VS), respectively) were operated to evaluate the effects of re-circulating an alkali-treated and untreated solid fraction of the digestate back to the reactors. The CSTRs were operated at an organic loading rate (OLR) of 2 kg VS m(-3) day(-1) and hydraulic retention time (HRT) of 20 days with a semi-continuous mode of feeding. The feasibility of co-digestion with substrate VS containing 30% VS of crop was reinforced, resulting in average specific methane yield of about 180-185 1 CH4 kg(-1) VS. Re-circulation of the solid fraction of digesta…

Rights with limits: biocultural rights - between self-determination and conservation of the environment

2015

Kabir Bavikatte has recently argued that a new 'basket' of group rights is emerging from the interpretation of multilateral environmental agreements, domestic law and case law, and from shifts in the development discourse and the struggles of communities. He refers to this new set of rights as 'biocultural rights' and defines them as being all the rights of indigenous peoples and local communities required to secure their stewardship role over their lands and waters. Biocultural rights build on two foundations: the self-determination and cultural diversity of indigenous peoples and local communities, and the conservation of the environment. This article suggests that the second foundation i…
