Architettura “cannibale” : nuovi progetti e lacerti di distruzioni
2019
The essay focuses on a list of architectures that preserve and sometimes flaunt parts of previous buildings, destined for demolition. This text explore different motivations and practices that can justify them preservation. Even if the randomness of the events directs towards responses that take into account unexpected economic difficulties, a persistent scepticism towards harmony and completeness emerges in many histories, as well as intriguing symbolic components.
PROCESSO CONSERVATIVO E SIGNIFICATIVITà UN APPROCCIO METODOLOGICO PER LA PROGETTAZIONE DEI SISTEMI DI PROTEZIONE NEI SITI ARCHEOLOGICI/CONSERVATION P…
2018
Patrimonio culturale in generale e dei beni archeologici in particolare, in ragione della loro duplice natura (materiale e immateriale) e coerentemente con l’interesse della Cultura tecnologica per la centralità di quegli aspetti di processo che sono determinanti per una loro adeguata valorizzazione e ampia fruizione, il presente contributo propone un modello di valutazione per capire ‘cosa’ conservare e ‘per- ché’ nell’ottica di uno sviluppo sostenibile, ancor prima di ‘come’ farlo, consentendo una più chiara lettura e una più agevole interpretazione delle complesse relazioni esistenti fra le preesistenze archeologiche, il contesto naturale e i sistemi antropici aggiunti. Il modello di val…

Generalized wave propagation problems and discrete exterior calculus
2018
We introduce a general class of second-order boundary value problems unifying application areas such as acoustics, electromagnetism, elastodynamics, quantum mechanics, and so on, into a single framework. This also enables us to solve wave propagation problems very efficiently with a single software system. The solution method precisely follows the conservation laws in finite-dimensional systems, whereas the constitutive relations are imposed approximately. We employ discrete exterior calculus for the spatial discretization, use natural crystal structures for three-dimensional meshing, and derive a “discrete Hodge” adapted to harmonic wave. The numerical experiments indicate that the cumulat…
Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe
2021
International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…
The proposal to transform an old limestone quarry into a botanical garden with a rainforest zone: a case study
2019
Nowadays, a significant part of cities is tackling the problems with post-mining areas. This manuscript is an original research which shows possibilities of their reclamation. The aim of the article is to present the proposal of developing the closed limestone quarry and creating a botanical garden. The proposed spatial solutions allow for creating a new, tourist and recreation space, maintaining the natural heritage. The work also assumed carrying out a dendrological inventory, in order to determine the existing dendrofl ora. The required spatial, nature and communication analyses, which illustrate the current condition of the area and defi ne further design works, have also been carried o…
Longhorn beetles of the Ficuzza woods (W Sicily, Italy) and their relationship with plant diversity (Coleoptera, Cerambycidae
2010
The woods in Sicily are the result of centuries of anthropogenic activities that have reduced the surface of wood and changed the original composition even with the introduction of alien species to native flora. The value in terms of biodiversity of these forests remains, however, high for they are the last refuge areas for many animals and plant species. This study was conducted within the Ficuzza woods (West Sicily), extended about 5,000 hectares on the slopes of limestone-dolomite rock of Busambra (1615 m asl), within which lies the largest remaining forest area in western Sicily. It is an area with a wide diversity of vegetation, represented mainly by native forests (holm oak, cork oak,…
First insights into female sperm storage duration in tardigrades.
2022
Female sperm storage is ubiquitous in the animal kingdom and it has been shown to be linked to several evolutionary processes, from postcopulatory sexual selection to dispersal. Here we report, for the first time, long-term sperm storage in females of the tardigrade Macrobiotus polonicus. Females, isolated after a short contact with a male, were able to use the stored sperm for up to 5 weeks (mean of 2 weeks), which translates to a considerable proportion of female post-mating longevity under controlled laboratory conditions (60% on average). Our study provides the first insights into the duration of sperm storage, an underexplored feature of the reproductive biology of tardigrades. Additio…
HAGHÌA TRIÀDA (CRETA): REINTEGRAZIONE DELLA LACUNA COME PRESENZA DELL’ASSENZA
2015
Il saggio intende presentare l’intervento, dei primi del sec. XX, nel palazzo-villa di Haghìa Triàda, nell’isola di Creta, per la conservazione del suo megaron. La sala possiede forma quasi quadrata, con sedili, ricoperti di lastre di gesso alabastrino, disposti nei tre lati; di fronte ad essa è una corte che la separa dall’esterno. La sala doveva avere una copertura sostenuta da pilastri di legno, che portavano le travi e i solai degli ambienti sovrastanti. Gli alloggiamenti, dove un tempo erano inseriti i pilastri di legno, risultavano perimetrati dalle lastre di gesso che ricoprivano le pareti della sala. In detti vani furono rinvenuti resti di legno carbonizzato, a testimonianza di un i…
Tree species influences diversity of ground-dwelling insects in afforested fields
2015
Abstract Impaired natural ecosystems, such as agricultural lands, are restored toward original or other target stage. Because the long agricultural history has changed the physical, chemical and biological features of the soil, afforested fields can harbor novel species assemblages and interactions. Our overall aim was to quantify the diversity of ground beetles and ants in early successional afforested fields. In a large scale field experiment, we compared plots that had been afforested 25 years ago by planting monocultures of birch, pine or spruce trees. A total of 4080 carabid individuals representing 41 species, and 131,933 ant individuals representing 15 species were recorded. Both the…
