Upside-down ship’s kel-shaped vaults as a contemporary design criteria. The case of the Palace of the Dukes of Braganza in Guimarães (Portugal)
2015
A contemporary worldwide trend is exposing the structural elements of a building to create an articulate and complex architecture whose lines of force give robustness, stability and, at the same time, a sort of lightness and frivolity to the entire construction. However, the combination between the visual conception of architecture and the principles of statics is not new to the world of construction. Exposed structure as a design approach may be observed in many historical buildings, either public, religious or private, and in several cultural and geographical areas where exposed structures communicate power, solidity, and rigour along with an instance of economy and lightness. In this wor…
Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…
2014
The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…
Biodeterioration of the Wooden Roof of the Phnom Penh National Museum
2017
Within the framework of a training program in Cambodia, during a visit to the National Museum in Phnom Penh, the most important in the Kingdom of Cambodia, the authors noted the presence of some signs of a termite attack in the secondary elements of the roof of an inner garden. Following this observation, a further investigation was performed in order to evaluate the phytosanitary condition of the wooden bearing element of the roof. The inspection highlighted the presence of severe decay, constituting a real danger for the integrity of the roof; consequently, an intervention of restoration, conservation and safeguard was considered to be necessary and urgent. This paper presents the results…
Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light
2017
Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…

Actividad física y uso sedentario de medios tecnológicos de pantalla en adolescentes
2013
Los beneficios asociados a un estilo de vida activo adquieren una especial importancia cuando nos referimos a niños y jóvenes por sus repercusiones a corto y a largo plazo, de modo que convierten a la actividad física en un elemento clave para las políticas sociales y de salud de las distintas administraciones públicas. A la preocupación que suscita la práctica física entre los adolescentes, se le añade el uso creciente de los medios tecnológicos de pantalla por parte de la población joven, que puede mermar o condicionar su práctica física diaria. La presente tesis doctoral consiste en una investigación epidemiológica sobre una muestra representativa de adolescentes españoles que ascendió a…
ATTIVITÁ DI RICERCA PER LO SVILUPPO DELLA ZOOTECNIA BIOLOGICA IN SICILIA
2008
Con l’intento di contribuire allo sviluppo del settore zootecnico biologico, gli autori hanno realizzato, attività di ricerca rivolte: - allo studio della possibilità di inserire, nella razione alimentare delle bovine e delle pecore in lattazione, fonti alternative al mais e alla soia, con la finalità di superare il problema degli OGM e di ridurre il rischio di contaminazione degli alimenti con micotossine; - alla valutazione degli effetti del carico animale al pascolo, finalizzato ad una maggiore efficienza produttiva dei sistemi pascolivi destinati agli ovini; - alla individuazione dei riflessi della dieta, variabile in funzione del concentrato utilizzato e del carico al pascolo, sulla qu…

Innovative Approaches for Organizing an Inclusive Optics and Photonics Conference in Virtual Format
2023
The COVID pandemic is forcing the renewal of scientific conferences, offering opportunities to introduce technological and inclusive developments. Our analysis focuses on the implementation of inclusive practices for female and early-career researchers in a virtual scientific conference. This organization approach was applied in the XIII Spanish Optical Meeting (RNO2021), which was also characterized by avatars interacting in an online metaverse. The effectiveness of inclusive policies and novel technological tools was evaluated using the participation data and a post-conference survey. Our study reveals the high impact of inclusive actions and a strong interest in the scientific community …
