Modulo resiliente di un’argilla a scaglie trattata con calce come parametro meccanico per l’impiego in strati di sottofondazione stradale
2016
La nota presenta i risultati di un programma sperimentale mirato alla valutazione della possibilità di utilizzare le argille a scaglie trattate con calce come materiale di sottofondo per opere di Ingegneria Civile. Tali risultati evidenziano che le caratteristiche di tale materiale migliorano rapidamente nel tempo e che esso diventa, dopo 28 giorni dal trattamento, molto stabile nei riguardi delle sollecitazioni dinamiche indotte dal traffico veicolare, simulate in laboratorio attraverso l’esecuzione di prove di compressione triassiale cicliche mirate alla misura del modulo resiliente.
Building community spaces: Processes and actions In the City of Mercato Ballarò in Palermo
2022
The rediscovery of the cultural value of a project, the creation of new imagery in marginal places and the new aesthetics of temporality are some of the emerging issues in the city of crisis which are measured through processes of active involvement in community relations. There are many cities that have recognised urban markets as an integral part of local economies, with great benefits also at cultural and social levels. The hypothesis of triggering regenerative processes in the urban and social fabric in the unstable urban market context is the foundation of this research-action contribution developed through active relationships with public entities, associations and citizens. The syste…
Regenerating Landscape from Resilient Citizens: Parco Uditore, Three Years of "Low Cost Landscape"
2016
In the always surprising capital of Palermo, a hidden garden of opuntia indica relics has been discovered again after decades of oblivion, due to the work and the unceased promotion made by a huge group of citizens, students, teachers and volunteers. In this 9 hectares area owned by the regional government of Sicily since a long time ago (1963), the remains of a dense opuntia plantation characterizes a green forgotten area, casually survived to the building growth of Palermo. Along three decades (1963‐1993) after being a military underground stowage plant for fuel in WWII, the Fondo Uditore is still a full opuntia place, where the sweet fruits and the green and prickly “leaves” where sold r…
Ex-Ante Business Model Evaluation Methods: A Proposal of Improvement and Applicability
2019
[EN] Purpose: The purpose of this paper is to choose the best method for ex ante business model evaluation, improve it and provide a framework to put it into practice. Design/Methodology/Approach: After an in-depth review, we chose the best method for ex ante business model evaluation, improved this method, and applied it to a real case study in which business models had been proposed for a Sustainable Smart District project. Findings: We analysed existing ex ante business model evaluation methods, justifying our choice of the best one. We improved this key question-based method by combining classic management tools and a new, promising procedure. We finally found a strong tool to improve b…
Triblock SEBS/DVB crosslinked and sulfonated membranes: Fuel cell performance and conductivity
2021
[EN] A set of styrene-ethylene-butylene-styrene triblock copolymer (SEBS) membranes with 10 or 25 wt.% divinyl-benzene (DVB) as a crosslinking agent were prepared and validated. Physicochemical characterization revealed suitable hydrolytic and thermal stability of photo-crosslinked membranes containing 25%wt. DVB and post-sulfonated. These compositions were evaluated in H2/O2 single cells, and electrical and proton conductivities were furtherly assessed. The membranes with the milder post-sulfonation showed greater proton conductivity than those with excessive sulfonation. In terms of electrical conductivity, a universal power law was applied, and the values obtained were low enough for bei…
Influence of substrate and temperature on the biodegradation of polyester-based materials: Polylactide and poly(3-hydroxybutyrate-co-3-hydroxyhexanoa…
2020
[EN] The extended use of polymers from renewable resources such as aliphatic polyesters or polyhydroxyalkanoates boosted the necessity to understand their behaviour in an end-of-life scenario. Although they can be degraded in reasonable shorter times than traditional polymers, understanding the degradation mechanisms under dissimilar conditions will contribute to further developments in this field. This work aimed to study the effect of temperature and substrate in the degradation of polylactide (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) in a simulated laboratory scale to ascertain their contribution, separately or in combination. For this purpose, nine parallel degradat…
Repeated Load Triaxial Testing of Recycled Excavation Materials Blended with Recycled Phyllite Materials
2022
Recycled Excavation Materials (REM) are becoming viable alternative construction resources due to their economic benefits. However, REM may be composed of weak rocks, e.g., phyllites, limiting the use in a base layer. The present paper attempts to further the knowledge of the mechanical performance of REM by performing Repeated Load Triaxial Tests (RLTT). REM are mixed with Recycled Phyllite Materials (RPM) in systematic blends of 0%, 25%, 50%, and 100%. The batches’ resilient modulus (MR) and permanent deformation (PD) characteristics were assessed to establish the maximum RPM allowed into REM while maintaining the required performance. Hicks and Monismith’s and Uzan’s mo…
Marco conceptual y componentes clave para el seguimiento y evaluación en la ordenación del territorio
2019
[EN] Researchers and practitioners in spanish spatial planning have an absence of conceptual framework to manage monitoring and evaluation processes in Spain. The aim of this work is to analyze the main theoretical frameworks related to spatial planning monitoring and evaluation. Key factors and components have been identified in order to make a preliminary conceptual framework proposal. To do that, the relevant international and national academic literature has been examined. Also the autonomous communities¿ spatial planning systems have been analyzed. The proposal highlights the importance of territorial governance. The coordination experience among territorial actors seems crucial. Furth…
La forza politicizzante del dolore: le resilient communities in Messico
2014
La violenza di genere è una problematica che affligge l’intero Stato del Messico, in particolar modo la zona fronteriza del nord tra cui Ciudad Juárez, Tijuana, quella centrale dello stato del Michoacán e Guanajuato e la zona sud in Oaxaca e Chiapas. La violazione dei diritti umani universali, che sfocia in atti di femminicidio e casi di violenza sessuale, è interpretabile in relazione al contesto storico-culturale, in quanto sia il passato postcoloniale di matrice spagnola sia quello contemporaneo capitalista prettamente statunitense ha contribuito all’affermasi di una politica dello sfruttamento basato sulla corruzione politica e la criminalità. Il presente contributo propone, pertanto, u…
Multiscalarity of Adaptive Architecture. The efficiency of micro and the resilience of macro in contemporary design
2020
Dealing with the multiscalar approach of contemporary architectural design raises the question of which architecture today is willing to accommodate a constant comparison between different scales, materials, and practices. It is believed that the processes that best show this purpose are related to resilient architecture, which elaborates innovative features through adaptive processes. With the introduction of external factors to the building as design materials, adaptive architecture can be considered as a transformative condition for some invariants of the discipline. The resilient and adaptive approach, therefore, uses technological elements, whose scale is Micro, embedded in the buildin…
