Approche responsable pour le patrimoine : coopération, participation, documentation / Approccio responsabile al patrimonio architettonico: cooperazio…
2014
Nel quadro del Programma Italie Tunisie, l’esperienza del Progetto APER viene introdotta con riferimento ai diversi livelli e alle opportunità della cooperazione: tra realtà transfrontaliere, tra istituzioni dello stesso Paese e tra studiosi di diverse discipline. Passando ai contenuti scientifici, dopo aver illustrato il campo di applicazione e le potenziali ricadute, si pone l’accento sul tema dell’integrazione tra salvaguardia e valorizzazione, come sintesi teorica e operativa degli obiettivi del Progetto APER. Seguendo l’evoluzione dell’approccio al patrimonio architettonico, dall’origine dello stesso concetto allo sviluppo degli obiettivi della conservazione prima e della valorizzazion…
COMPARISON OF CRIMSON FOUNTAINGRASS AND DISS FIBRES AS AGGREGATES FOR CEMENT MORTARS
2019
The use of natural fibres in cement composites is an expanding research field as their use can improve the mechanical and thermal behavior of cement mortars and reduce their carbon footprint. In this paper two different wild grasses, i.e. Pennisetum Setaceum, also known as crimson fountaingrass, and Ampelodesmos Mauritanicus, also called diss, are used as source of natural fibres for cement mortars. The principal aim is to evaluate the possibility of using the more invasive crimson fountaingrass in place of diss inside cement based vegetable concrete. The two plants’ fibres have been characterized by means of electron microscopy, helium picnometry; moreover, the thermal conductivity of fibr…
NATURALLY AVAILABLE SOLUTIONS FOR BUILDING NEW METABOLIC TERRITORIES
2021
Building new metabolic territories is a proactive way of responding to the challenges and precariousness of the contemporary city. Byintegrating solutions inspired by new scientific advances in urban ecology, cities are able to address some of the environmental threats. Many European cities are implementing alternative nature-based solutions to protect their health and tackle water scarcity, land consumption and climate change, to increase citizens' well-being. Wellbeing and health (Agenda 2030) are the most important analytical parameters for measuring the results and impacts of environmental project actions. With this in mind, the study presents a "nature-action" project hypothesis for wh…
Sistemi costruttivi tradizionali in gesso nell’architettura siciliana
2020
Chalks outcrops characterize all the central-western territory in Sicily. They are different in types and extension and tangibly mark the presence of the well-known sulphurus chalky series. In the same areas it is possible to see several traditional buildings built, even in their structures, using gypsum, an material which is unusual in other contexts. In some cases the chalk outcrop makes up even the base of a building. This text describes different kinds of walls, floors, vaults and flooring where gypsum is the main material.
TRADITION AND INNOVATION IN HOSPITALITY: Palermo, International Design Competition
2009
There is an on-going debate today on the subject of the relationship between city and architecture; this cultural and disciplinary backdrop requires in-depth studies on a variety of themes and a great number of disciplinary contributions. Over the centuries Man has left his mark on the land and in order to fully understand the wide- ranging modifications, it could be important to assess architecture specifically built for hospitality; in particular, its conceptual, spatial, functional and technological peculiarities need to be considered. These have undergone gradual changes over the course of time, in a continuing attempt to try to guarantee a high level of quality for guests. The project …
Land Healthcare Resilience and Technology
2020
The Covid 19 pandemic and emergency has highlighted the precarious conditions in urban and areas and has bettered opportunities offered by smaller towns and inland areas in which the healthy atmosphere, sparser population and sustainable relational system represent alternative ways of life, guaranteeing physical space and health controls without actually entailing social distancing and isolation. This is even more crucial for the weaker elements, of any age and condition, for whom a different model of living embodies prudence and prevention. The marginality of services represents a limitation on the possibility of transforming villages and small towns into alternatives with regard to qualit…

Ancient bridges of Sicily: punctual signs of a past that disappears
2018
Sono indelebili i segni lasciati dall’uomo sul territorio, testimonianze che il tempo conserva e la storia ci consegna e il cui insieme costituisce una trama fittissima che si sovrappone alla struttura fisica dell’ambiente, integrandolo e modificandolo. Grandi opere, monumenti universalmente riconosciuti come capolavori della mente e delle mani dell’uomo, ma anche opere minori, manufatti d’uso comune, beni isolati che costituiscono gli elementi puntuali di una più vasta e complessa organizzazione di fenomeni insediativi, le tessere di un mosaico ricco di sfumature e riflessi, frutto di un lungo processo di stratificazione storica. Alla categoria dei beni isolati appartengono le torri, i cas…
Mechanical behavior of carbon/flax hybrid composites for structural applications
2012
In this work, the influence of an unidirectional carbon fabric layer on the mechanical performances of bidirectional flax fabric/epoxy composites used for structural applications was studied. Two different bidirectional flax fabrics were used to produce flax fabric reinforced plastic (FFRP) laminates by a vacuum bagging process: one is normally used to make curtains; the other, heavier and more expensive than the previous one, is usually used as reinforcement in composite structures. In order to realize hybrid structures starting from FFRP, an unidirectional UHM carbon fabric was used to replace a bidirectional flax fabric. Tensile and three-point bending tests were performed to evaluate t…
