La città e le sue rappresentazioni. L’éclatante folie della Lecce barocca nelle impressioni dei viaggiatori stranieri (secc. XVIII-XX)
Get PDFDalla metà del Settecento la Puglia e la Terra d’Otranto sono inserite tra le tappe del Grand tour in Italia, attirando numerosi viaggiatori stranieri alla scoperta del glorioso passato dell’antica civiltà greca e romana. Il contributo si propone di cogliere, lungo l’arco di più di due secoli e attraverso le testimonianze di viaggio dei visitatori forestieri, le interrelazioni tra percezione, comunicazione, rappresentazione del paesaggio urbano della città di Lecce, che si caratterizza sul piano artistico-culturale per l’éclatante folie del suo barocco, tra passato sedimentato, teatralità esibita e spinte innovative

Get PDFChronic wounds represent a major clinical challenge due to their prolonged
healing process and susceptibility to bacterial colonization, particularly by biofilm-forming
bacteria. To address these issues, in this work, silver-treated silk fibroin scaffolds were
developed and tested as multifunctional wound dressings, combining antimicrobial and
regenerative properties. Silk fibroin, a natural protein derived from Bombyx mori cocoons,
is widely recognized for its biocompatibility and suitability for tissue engineering. In this
study, porous silk fibroin scaffolds were functionalized with silver nanoparticles through a
photo-reduction process and were comprehensively tested for their cytocompatibility and
wound healing potential. The excellent antibacterial activity of the silver-treated scaffolds
was demonstrated against Escherichia coli and antibiotic-resistant Pseudomonas aeruginosa,
as was extensively reported in a previous work. Biological assays were performed using
3T3 fibroblasts cultured on both untreated and silver-treated silk fibroin scaffolds. Biocompatibility assays, such as MTT, Live/Dead, and cytoskeleton analyses, demonstrated
biocompatibility in both scaffold types, comparable to the control. Wound healing potential was assessed using in vitro scratch assays, revealing full wound closure (100%) after
24 h in cells cultured with untreated and silver-treated silk fibroin scaffolds, in contrast to
78.5% closure in the control. Notably, silver-treated scaffolds exhibited enhanced fibroblast
repopulation within the wound gap, suggesting a synergistic effect of silver and fibroin in
promoting tissue regeneration. These findings demonstrate that silver-treated silk fibroin
scaffolds possess both anti-microbial and regenerative properties, making them promising
candidates for chronic wound management applications
Comparison of Pulse-Echo Tomography and Through-Transmission Ultrasonic Test for UPV Characterization of Building Materials
Get PDFUltrasonic pulse velocity (UPV) is a widely used technique for diagnosis and structural safety assessment of existing buildings. The main difficulties in UPV tests on-site are due to one-sided accessibility of materials and degraded/irregular surfaces. Pulse-echo ultrasonic tomography (PE-UT) can overcome the problem. Though it has been widely applied for detecting inhomogeneities within concrete, few works use the instrument to assess UPV. The present paper aims to fill the gap by comparing PE-UT results with those of through-transmission ultrasonic tests (TT-UT) commonly used for UPV characterization. TT-UT measurements were performed with cylindrical and exponential transducers. The latter are used on irregular surfaces or when coupling gel is forbidden. Few data are in the literature comparing exponential and cylindrical transducers’ results. This is a further element of novelty of the paper. PE-UT and TT-UT results were compared considering the effect of material compositeness, water, transmission mode, and transducer type. It was found that PE-UT allows for reliable and rapid one-sided measurements on concrete and stone in different conditions. The differences between PE-UT and TT-UT results were between 1 and 3%. Exponential transducers gave reliable results on fine-grained stone in direct transmission, with differences lower than 4% with cylindrical transducer results
Le esperienze non egologiche nelle forme dell’intenzionalità collettiva sonora
Get PDFIn this paper, I try to outline the phenomenological fundament of the collective experiences which emerges along with the sound phenomena of the masses. Through an analysis of the phenomenological modes of affect, as Scheler tried to point out for the affective contagion, and through the reflection on non-self-referential forms of consciousness, I will attempt to comprehend the collective forms of intentionality

Digitalizing Bank Branches with a New Multichannel Standard to Address Office Closures in Europe
No full textThe growing phenomenon of bank branch closures, driven by rising operational costs and the need to meet specific KPIs, is reducing access to banking services, especially in remote areas. At the same time, the adoption of new technologies, such as XR, opens up opportunities to rethink the branch experience from a digital perspective. However, the lack of a shared standard limits the development of scalable and interoperable solutions, leaving implementations to isolated initiatives by individual banks. To address this issue, we propose the concept of Open Branching, inspired by Open Banking, which has already transformed the financial sector through digitalization and the use of APIs. Open Branching extends this philosophy to physical branches, enabling the provision of all traditional banking services in a digital format, ensuring continuity in the user experience and greater accessibility. This approach facilitates the integration between the physical and digital worlds, enabling new interaction modes such as XR and the Metaverse. In collaboration with one of the leading Italian banks, within the MilanoHub program, we have developed and standardized a taxonomy of the main products and services offered in branches, classifying them by type and releasing it under an open-source license. This standard provides a structured foundation for implementing new ways of accessing banking services, allowing third-party operators to enhance the customer experience in traditional branches. The validity of the standard has been demonstrated through a case study focused on branch service access via the Metaverse, highlighting the potential of this innovation
Tradurre in latino poesie del Seicento: il caso delle 'Versiones' di Girolamo Cicala (1649).
No full textIl saggio si propone di analizzare in modo approfondito le diverse traduzioni latine di testi letterari italiani che furono composte dal poeta salentino Girolamo Cicala e incluse nella sua raccolta di 'Carmina' (pubblicata a Lecce nel 1649) in una sezione che reca il titolo di 'Versiones'. Questa sezione include numerosi testi, molto vari tra loro, che vanno dai sonetti di Petrarca (XIV secolo) a quelli di Giovanni Della Casa (XVI secolo), dalle liriche di Giovan Battista Marino (XVII secolo) alle poesie di Maffeo Barberini (XVII secolo). Il lavoro traduttorio compiuto da Cicala rappresenta il primo tentativo di creare un’antologia e un canone della letteratura italiana in traduzione latina, che tiene anche in conto i coevi dibattiti circa poesia classicista e poesia marinista
The Differential Impact of Clear Aligners and Fixed Orthodontic Appliances on Periodontal Health: A Systematic Review
No full textBackground/objective: In orthodontic therapy, the periodontal ligament plays a critical role in the bone remodeling process by stimulating osteoblasts in tension zones and promoting bone resorption through osteoclasts in compression zones in response to mechanical stress. These processes are regulated by key cytokines, such as RANKL and IL-1, which are influenced by factors such as patient age and force application. This work evaluates the effectiveness of clear aligners versus traditional braces on periodontal health in patients with periodontitis, following PRISMA guidelines and utilizing specific inclusion and exclusion criteria. Methods: A systematic review of 1664 records was conducted, leading to the inclusion of eight studies that focus on the impact of orthodontic treatments on periodontal health. The review identifies various biases present in the literature. Results: The findings reveal that clear aligners, in contrast to fixed appliances, improve oral hygiene and reduce inflammation, leading to better periodontal outcomes. Fixed appliances, on the other hand, may exacerbate plaque accumulation and inflammation, which can worsen periodontal health. Conclusions: Clear aligners offer advantages over fixed appliances in terms of enhancing periodontal health, improving patient compliance, and providing long-term benefits, particularly in patients with severe periodontitis. The effectiveness of clear aligners is linked to better management of periodontal complications and overall oral hygiene. Treatment decisions should be based on patient-specific criteria to optimize outcomes
