A Preliminary Investigation on the Thermal Performance of a Hydroponic Roof System in Mediterranean Climate
No full textThis study investigates the thermal performance of a hydroponic roof
system as an alternative strategy to an extensive green roof taking as a case study
a prefabricated building module situated in the Mediterranean climate of Catania
(Italy). Through dynamic simulations carried out with TRNSYS, the research
compares the thermal behaviour of a hydroponic roof, an extensive green roof
and a lightweight roof with the aim of understanding the effectiveness of the hydroponic solution in reducing the peak roof internal surface temperature and incoming heat flux.
The findings indicate that a hydroponic roof system can reduce the peak value of
the internal roof surface temperature of 2.7°C and delay by more than 10 hours
the peak of the incoming heat flow, which is almost halved with respect to the
lightweight roof solution

La spécificité africaine de l'approche de la notion de terrorisme international?
No full textCette thèse analyse en profondeur la construction historique, normative et conceptuelle d'une approche africaine spécifique face au terrorisme international, la distinguant fondamentalement de la conception occidentale dominante. Ancrée dans le contexte du droit international des Tiers-Mondes (TWAILS), l'étude retrace l'évolution de cette approche depuis les prémices coloniales jusqu'à l'ère post-11 septembre 2001.En premier lieu, cette thèse explore l'émergence de cette approche en examinant les travaux pré-indépendance, notamment ceux du BIUDP et de la SdN (Convention de 1937), qui ont établi une définition du terrorisme excluant ou assujettissant les populations et les territoires colonisés par le biais de la clause coloniale. L'étude démontre comment l'accession à la souveraineté des États africains, sous l'impulsion de la première génération des TWAILs, a marqué une rupture dès les années 1970. Agissant comme de véritables « entrepreneurs normatifs », les États du « Grand Sud » ont contesté la définition occidentale, insistant sur la primauté des causes profondes (colonialisme, racisme, apartheid, discrimination) et assimilant l'oppression étatique à des formes de « terrorisme », comme en témoigne la Résolution 3034 (XXVII) de 1972 de l'Assemblée Générale. Cette approche dialectique a longtemps conditionné le développement d'une convention générale et le contenu des instruments sectoriels.En second lieu, cette thèse analyse l'évolution de cette approche de 1972 à 2001, période marquée par la Guerre Froide et l'adoption de conventions régionales. L'étude confronte les instruments américain (OEA) et européen (Conseil de l'Europe) à la Convention de l'OUA de 1999, qui, tout en condamnant le terrorisme, maintient une clause d'exclusion en faveur du droit à l'autodétermination des peuples. Elle examine également comment les États africains ont milité pour une « approche coopérative, juste et équitable » face aux tentatives d'unilatéralisme et d'instrumentalisation du Conseil de sécurité (notamment dans l'affaire Lockerbie).Enfin, la thèse se concentre sur l'impact de l'après-11 septembre 2001. Face à l'hypertrophie normative et administrative du Conseil de sécurité (Résolutions 1373 et Comité des sanctions), l'approche africaine s'est affirmée par une résistance institutionnelle, plaidant à l'Assemblée Générale pour une Stratégie mondiale qui intègre la recherche des causes profondes et une définition globale excluant les luttes de libération nationale. Au niveau régional, l'Union Africaine (UA) a institutionnalisé cette lutte, adoptant une approche multidimensionnelle qui dépasse le seul prisme sécuritaire. Le recours à la force contre le terrorisme en Afrique (cas de l'AMISOM, du Mali et de Boko Haram) est analysé à l'aune du Droit de l'UA (Article 4(h)), révélant les tensions entre la théorie de la non-ingérence et la pratique des interventions consenties ou régionales.En conclusion, cette recherche établit que la spécificité africaine réside dans une lecture constructiviste du droit international, où la lutte contre le terrorisme est envisagée comme un triple impératif – sécuritaire, juridique et structurel – et un levier de construction étatique face aux héritages historiques de l'oppression
L’Università come ecosistema comunitario e sostenibile: un’esperienza di formazione degli adulti educatori
No full textNel quadro dell’Agenda 2030 delle Nazioni Unite, la sostenibilità è emersa non solo come obiettivo politico, ma come paradigma culturale e pedagogico che interpella profondamente i sistemi educativi. Il tema della sostenibilità, che si si impone in termini di emergenza ambientale, sociale, culturale e politica, si interseca con un sempre crescente bisogno di formazione degli adulti educatori. Come suggerisce la letteratura di riferimento, infatti, nei contesti formali di istruzione oltre che incrementare le conoscenze ecologiche è necessario formare mentalità ecologiche, capaci di riconciliare la relazione tra persona e ambiente di riferimento, oggi più che in passato compromessa. A partire da tale premessa, nell’ambito del Master in Scienze dell’Educazione dell’Università di Friburgo è stata svolta un’esperienza di formazione dal titolo “Burnout, helping professions and adult education”. La finalità generale di questo percorso formativo è stata promuovere e rafforzare la consapevolezza ecologica non solo attraverso l’incremento di conoscenze e capacità oerative bensì attraverso il rafforzamento dell’azione collettiva, riflessiva e narrativa.
Il presente contributo intende descrivere le premesse teoriche, le fasi e gli strumenti utilizzati durante l’intervento formativo, con particolare riferimento ad un questionario con item a completamento e una attività di photovoice. Tali strumenti e metodologie hanno permesso di valorizzare la narrazione intesa quale possibilità per dar forma all’esperienza attraverso la ricerca condivisa di significati. L’approccio che ha guidato l’analisi del materiale narrativo è quello fenomenologico-ermeneutico, il quale, offrendo uno sguardo in prima persona radicato nell’esperienza vissuta dai partecipanti, permette di comprendere - seppur per profili e adombramenti - il fenomeno oggetto di indagine. In questi termini, un’università che promuove processi formativi che consentono ai soggetti di acquisire competenze e coltivare attitudini per pensare a agire con empatia, responsabilità e cura per il nostro pianeta può essere considerata come un ecosistema comunitario e sostenibile capace di far fiorire un pensiero ecologico condiviso
The International Law Commission’s Study Group on Sea Level Rise in Relation to International Law and Its Impact on International Law
No full textThis chapter analyses the working method followed so far by the Study Group of the International Law Commission in its work on the topic of ‘Sea Level Rise in Relation to International Law’. More precisely, it identifies and discusses two questions: (1) whether suggesting ‘practical solutions’ to States for dealing with the impacts of sea level rise on maritime zones (i.e. one of the two main tasks of the Study Group) falls within the mandate of the International Law Commission, and (2) whether the practical solutions suggested by the Study Group have already had an impact on State practice and opinio juris.
In this respect, the chapter argues that the Study Group's main contribution lies not so much in its support for the idea that the Pacific Island States’ interest in maintaining their sovereignty and jurisdiction over maritime zones is best assured by adopting a teleological interpretation of the LOSC, but rather in its promotion of a process of formation of a customary rule, though this process has not yet been consolidated
The Biblical Heritage in Ancient Latin Christian Literature: Advancing Intertextual Mapping Through Sentence Embeddings
No full textThis study presents an interdisciplinary methodology for detecting intertextual references in Latin patristic literature through a novel combination of philological rigor and Natural Language Processing (NLP) techniques. Focusing on Augustine of Hippo’s 'De Genesi ad litteram' and its relationship to Latin biblical texts (specifically Jerome’s Vulgate and pre-Vulgate versions), this research introduces a token-based classification system enriched with semantic annotations, supported by the INCEpTION platform. The classification system accounts for exact matches, lemmatized forms, synonyms, and structural parallels, capturing a wide spectrum of textual similarity. To enhance automatic retrieval of these intertextual links, we fine-tune BERT-based language models for Latin, incorporating contrastive learning and hard negative mining. Experimental results demonstrate that fine-tuned models significantly outperform baselines across varying levels of textual similarity. This work highlights the utility of computational models in bridging explicit citations and implicit allusions, offering a scalable approach for the study of biblical intertextuality in ancient texts
Improving the Accuracy of Optical Satellite-Derived Bathymetry Through High Spatial, Spectral, and Temporal Resolutions
No full textAccurate nearshore bathymetry is essential for various marine applications, including navigation, resource management, and the protection of coastal ecosystems and the services they provide. This study presents an approach to enhance the accuracy of bathymetric estimates derived from high-spatial- and high-temporal-resolution optical satellite imagery. The proposed technique is particularly suited for multispectral sensors that acquire spectral bands sequentially rather than simultaneously. PlanetScope SuperDove imagery was employed and validated against bathymetric data collected using a multibeam echosounder. The study area is the Gulf of Sciacca, located along the southwestern coast of Sicily in the Mediterranean Sea. Here, multibeam data were acquired along transects that are subparallel to the shoreline, covering depths ranging from approximately 7 m to 50 m. Satellite imagery was radiometrically and atmospherically corrected and then processed using a simplified radiative transfer transformation to generate a continuous bathymetric map extending over the entire gulf. The resulting satellite-derived bathymetry achieved reliable accuracy between approximately 5 m and 25 m depth. Beyond these limits, excessive signal attenuation for higher depths and increased water turbidity close to shore introduced significant uncertainties. The innovative aspect of this approach lies in the combined use of spectral averaging among the most water-penetrating bands, temporal averaging across multiple acquisitions, and a liquid-facets noise reduction technique. The integration of these multi-layer inputs led to improved accuracy compared to using single-date or single-band imagery alone. Results show a strong correlation between the satellite-derived bathymetry and multibeam measurements over sandy substrates, with an estimated error of ±6% at a 95% confidence interval. Some discrepancies, however, were observed in the presence of mixed pixels (e.g., submerged vegetation or rocky substrates) or surface artifacts
AISF-SIMIT practice guidance on treatment of hepatitis d virus (HDV): A 2025 update
No full textChronic hepatitis Delta virus (HDV) infection represents the most severe form of viral hepatitis, characterized by accelerated progression to cirrhosis, end-stage liver disease, and hepatocellular carcinoma. For decades, Pegylated Interferon (PegIFNα) has been the only therapeutic option, with limited efficacy and poor tolerability. The approval of the HBV/HDV entry inhibitor Bulevirtide marked a turning point, by providing the first anti-HDV specific antiviral drug. This position paper, developed jointly by the Italian Association for the Study of the Liver (AISF) and the Italian Society of Infectious and Tropical Diseases (SIMIT), updates prior national guidance by providing practical recommendations for diagnosis, staging, and treatment of chronic HDV infection
Sicilian Native Wool. From Waste to Resource. A Circular Supply Chain for Made in Sicily
No full textThis study focuses on Sicilian native wool, historically excluded from industrial supply chains due to its coarse morphology, and explores its regenerative potential across ecological, economic, and cultural dimensions. Developed within the MICS partnership, the research adopts a systemic and collaborative methodology that enables participatory design processes involving local stakeholders, artisans, and institutions. These processes generate application scenarios for the reuse of wool in textile production, educational programmes, and manufacturing contexts. The findings reveal the capacity of this marginalised material to be reconfigured as a high-value circular resource, capable of activating place-based supply chains, enhancing territorial competences, and fostering new forms of ecological citizenship. The project underscores the role of design as an enabling infrastructure for sustainable transitions rooted in proximity, mutualism, and care for place
