The proscenium of opera houses as a disappeared intangible heritage: a virtual reconstruction of the 1840s original design of the Alighieri Theatre in Ravenna

In a Historical Opera House (HOH), the proscenium is the foreground part of the stage. Until the end of the 19th Century, it was extended through the cavea, being the orchestra placed at the same level of the stalls, without an orchestra pit. Soloists often moved in the proscenium when they sung, in order to increase the strength of the voice and the intelligibility of the text. The Alighieri theatre in Ravenna, designed by the Meduna brothers, the former designers of Venice\u2019s \u201cLa Fenice\u201d theater, is chosen as a case study. During a refurbishment in 1928, the proscenium of the stage was removed in order to open the orchestra pit, which was not considered in the original design. The original design and the present one are compared by using numerical simulations. Acoustic measurements of the opera house and vibro-acoustic measurements on a wooden stage help to reach a proper calibration of both models. Results are discussed by means of ISO 3382 criteria: the proscenium increases the sound strength of the soloists but reduces the intelligibility of the text

A Virtual Acoustic Restitution of St John\u2019s Baptistery in Pisa

Virtual acoustics is a useful tool for studying ancient environments now part of our cultural heritage. The acoustic restitution of an existing building, or even of a no more existing building, allows understanding its acoustic and architectural evolution. St. John\u2019s Baptistery is located in Piazza dei Miracoli (Pisa), which is a homogenous architectural ensemble including the Leaning Tower and the Cathedral. Due to the succession of different masters, the Baptistery was built in stylistic disagreement with the earliest design, resulting in the actual architecture that provides interesting acoustic peculiarities. This work presents the virtual acoustic restitution of potential first designs, based on previous studies. The accurate calibration of the existing Baptistery model enables us to achieve a believable acoustic restitutions through the auralisation techniques. More in details the acoustic coupling between the volumes of the building \u2013 respectively the dome, the matroneum and the ambulatory \u2013 was studied with measurements and numerical simulations. Furthermore, the layout of a Gregorian soloists in the choir part of the Baptistery was simulated according to musicological researchers, both in unoccupied and occupied conditions

Qualit\ue0 acustica del palcoscenico di un teatro all\u2019italiana per setup pop-rock

E' sempre pi\uf9 frequente l'uso di teatri storici all'italiana per esecuzione di musica pop e rock. I parametri acustici dei palcoscenici sono tradizionalmente riferiti a musicisti con strumentazione classica. Nel caso di un palco pop-rock le sorgenti sul palcoscenico risultano molteplici e non omogenee: acustiche (batteria) e elettroacustiche con differenti direttivit\ue0 (amplificatori degli strumenti, monitor, side fill, etc...). Il Teatro Consorziale di Budrio \ue8 un teatro all\u2019italiana con tre ordini di gallerie capace di circa 500 posti e vede una stagione di spettacoli in cui si alternano prosa, concerti di musica leggera, musica sinfonica e lirica. Pu\uf2 essere quindi considerato un caso di studio adeguato per un\u2019analisi preliminare su metodi e descrittori per la caratterizzazione di un palcoscenico per musica pop-rock

Objective musician\u2019s criteria in Italian historical theatres

Musicians\u2019 objective criteria have been proposed in the literature basing on measurements done in concert halls. The stages of the Italian historical theatres are designed to host opera scenes and singers. Orchestras plays often on the stage, due to larger availability of opera houses compared to concert halls in Italy. Acoustic conditions on these stage are not optimized for the symphonic playing; several theatres have orchestra shells but they are not often used due to the high operating costs. The acoustics of the stages of four Italian historical theatres have been measured using objective criteria proposed in the literature

Piattaforma informatica per l\u2019orientamento universitario. L\u2019esperienza del Progetto Ariann@

Il progetto Ariann@ si basa su una piattaforma telematica per l\u2019orientamento universitario. L\u2019analisi delle soluzioni software open source ha evidenziato l\u2019assenza di un prodotto completamente rispondente alle esigenze del progetto. Per colmare tale lacuna sono stati integrati supporti di collaborazione utente-utente e piattaforma-utente attraverso lo sviluppo di tecniche sincrone di comunicazione

Sonic crystals as tunable noise barriers

This work reports an introduction to the topic of wave propagation in sonic crystals and a review of the recent scientific literature. The paper presents the results of some experimental investigations carried out at the University of Bologna by discussing Insertion Loss measurements, measurements performed inside the lattice and sound intensity measurements. Finally, the Sound Insulation Index measured for a sonic crystal is compared to the values measured for common noise barriers, pointing out that sonic crystals reach insulation values comparable to the maximum Insertion Loss achievable due to the top edge diffraction

Weekly alternate intensive regimen FIrB/FOx in metastatic colorectal cancer patients: an update from clinical practice

Background: Several trials evaluated the role of intensive regimens, made of triplet chemotherapies plus bevacizumab, as first-line treatment for patients with metastatic colorectal cancer (mCRC). We previously reported, in a Phase II prospective study, the efficacy and the tolerability of FIrB/FOx regimen, reporting interesting results in terms of received dose intensities (rDIs) and safety. Methods: We reported a retrospective update of 85 patients treated with FIrB/FOx, an intensive regimen of 5-fluorouracil, bevacizumab, and weekly alternate irinotecan and oxaliplatin, to confirm its feasibility in \u201creal life\u201d. Subgroup analyses were performed, particularly among patients treated with standard and modified FIrB/FOx (based on age, performance status, and/or comorbidities). Results: Overall, 3-month objective response rate (ORR) and 6-month ORR were 75.9% and 55.3%, respectively. Median progression-free survival (PFS) and median overall survival (OS) were 14.4 and 34.9 months, respectively. Among the patients treated with standard and modified regimens, 3-month ORR, PFS, and OS were 75.8% and 76% (P=1.0000), 14.4 and 14.4 months (P=0.8589), and 37.8 and 26.6 months (P=0.7746), respectively. Among the K/NRAS wild-type and K/NRAS mutant patients, 3-month ORR, PFS, and OS were 95.2% and 74.5% (P=0.0526), 15.3 and 14.4 months (P=0.8753), and 37.8 and 51.4 months (P=0.8527), respectively. The rDIs were 6580% of full doses both in the standard and in the modified regimens subgroups. Cumulative G3/4 toxicities were neutropenia (14.1%), diarrhea (17.6%), asthenia (9.4%), vomiting (5.6%), and hypertension (16.5%). Conclusion: This update shows that intensive regimens such as FIrB/FOx are also feasible options for first-line treatment of mCRC patients in the \u201creal-life\u201d setting
