Spettro trofico di due popolazioni sinantropiche di geco comune, Tarentola mauritanica (Linnaeus, 1758), in Sicilia sud-occidentale

2017

The Moorish gecko (Tarentola mauritanica) is a lizard belonging to the Phyllodactylidae family, with circum-Mediterranean distribution. Despite the species is widespread in Sicily, there are very few studies on its feeding behaviour. This paper analyzes the diet of two synanthropic populations located in southwestern Sicily (province of Trapani) and exposed to different environmental conditions. Fecal remains were collected along the outer walls of an inhabited house in the coastal village of Triscina and in an uninhabited rural house, located near Castelvetrano town. The first study area has been constantly affected by artificial light sources, which are absent in the second study area. Re…

Cultural content of lighting for the discovery of archaeological heritage

2013

Archaeological sites, built landscapes of the past, represent the identity heritage for future generations. The aim of this article is to investigate and demonstrate the importance of the cultural identity reinforcement, which can be achieved by enhancing the historical heritage through the use of artificial lighting. The charm of an archaeological site or a monument comes from the perception of its whole environmental context, both for the functional lighting and the enhancement of the artistic and monumental. Light can turn into concrete matter both in interiors, in archaeological and urban spaces: combining innovative technologies, artificial light can be used to change the world, to sha…

Assessment of indoor illuminance and study on best photosensors' position for design and commissioning of Daylight Linked Control Systems. A new meth…

2018

Abstract Artificial lighting systems have to ensure appropriate illuminance with high energy efficiency according to best design practice and technical standards. These aims can be tackled, by incorporating a Daylight linked control system. However, the system behaviour is strongly influenced by several factors and, in particular, by the sensors' position. Indeed, very often the illuminance on work-plane is not fully correlated with illuminance measured by the photo-sensor used to control the luminaires. This fact leads to wrong information for the Daylight linked control systems affecting its efficacy. The artificial intelligence of Neural Networks can be exploited to provide a method for …

Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica
