Lo spazio del chiostro, progetto di restauro del chiostro di San Giovanni Battista a Faenza

Tesi in Restauro Architettonico del chiostro di San Giovanni Battista a Faenza. L'edificio è situato in Vicolo San Giovanni Battista nel centro storico di Faenza. L'intervento prevede un restauro scientifico delle murature esistenti, e la progettazione di un nuovo volume in aggiunta per risolvere i problemi di accessibilità. La fase progettuale si sviluppa su tre campi: il volume in aggiunta in cui collocare elementi di collegamento, la rampa interna al chiostro per superare le differenze di quota e l’intervento al piano superiore in cui sviluppare uno spazio funzionale ad un attività.

I tre libri di salmi vespertini a otto voci (opp. I, VII e XI) di Giovanni Paolo Colonna

Le tre raccolte di salmi da vespro a otto voci nello stile pieno di Giovanni Paolo Colonna (Bologna 1637-1695), pubblicate rispettivamente nel 1681, nel 1686 e nel 1694 (opp.I, VII e XI), costituiscono un oggetto di studio privilegiato nell’ambito della ricca produzione a stampa dell’autore: in primo luogo, esse ebbero ampia e favorevole recezione, come testimoniano la diffusione degli esemplari, le ristampe, le copie manoscritte ricavate dalle edizioni; in secondo luogo, la fortuna postuma del compositore fu legata in buona parte alla sua musica sacra a doppio coro e, in particolare, al favore riscosso dai suoi libri di salmi; infine, l’analisi delle tre raccolte consente di confrontare le risorse tecniche e stilistiche messe in opera da Colonna in composizioni afferenti a uno stesso genere ma risalenti a periodi diversi. La dissertazione è articolata in tre parti: nella prima sono presi in esame gli ordinamenti liturgici secenteschi relativi alla celebrazione dei vespri, onde illustrare la cornice rituale alla quale i salmi di Colonna erano destinati, e si passano in rassegna alcune definizioni di stile pieno e di contrappunto a otto voci desunte dalla trattatistica coeva. La seconda parte è dedicata alla lettura storico-critica delle opp. I, VII e XI nel contesto generale della produzione dell’autore. La terza parte contiene l’edizione integrale dell’opera VII e XI, nonché una scelta di brani tratti dall’op. I.

Consensus standards for acquisition, measurement, and reporting of intravascular optical coherence tomography studies: a report from the International Working Group for Intravascular Optical Coherence Tomography Standardization and Validation

The purpose of this document is to make the output of the International Working Group for Intravascular Optical Coherence Tomography (IWG-IVOCT) Standardization and Validation available to medical and scientific communities, through a peer-reviewed publication, in the interest of improving the diagnosis and treatment of patients with atherosclerosis, including coronary artery disease.

Mass-movement and flood-induced deposits in Lake Ledro, southern Alps, Italy: implications for Holocene palaeohydrology and natural hazards

High-resolution seismic profiles and sediment cores from Lake Ledro combined with soil and riverbed samples from the lake's catchment area are used to assess the recurrence of natural hazards (earthquakes and flood events) in the southern Italian Alps during the Holocene. Two well-developed deltas and a flat central basin are identified on seismic profiles in Lake Ledro. Lake sediments have been finely laminated in the basin since 9000 cal. yr BP and frequently interrupted by two types of sedimentary events (SEs): light-coloured massive layers and dark-coloured graded beds. Optical analysis (quantitative organic petrography) of the organic matter present in soil, riverbed and lacustrine samples together with lake sediment bulk density and grain-size analysis illustrate that light-coloured layers consist of a mixture of lacustrine sediments and mainly contain algal particles similar to the ones observed in background sediments. Light-coloured layers thicker than 1.5 cm in the main basin of Lake Ledro are synchronous to numerous coeval mass-wasting deposits remoulding the slopes of the basin. They are interpreted as subaquatic mass-movements triggered by historical and pre-historical regional earthquakes dated to AD2005, AD1891, AD1045 and 1260, 2545, 2595, 3350, 3815, 4740, 7190, 9185 and 11 495 cal. yr BP. Darkcoloured SEs develop high-amplitude reflections in front of the deltas and in the deep central basin. These beds are mainly made of terrestrial organic matter (soils and lignocellulosic debris) and are interpreted as resulting from intense hyperpycnal flood event. Mapping and quantifying the amount of soil material accumulated in the Holocene hyperpycnal flood deposits of the sequence allow estimating that the equivalent soil thickness eroded over the catchment area reached up to 5mm during the largest Holocene flood events. Such significant soil erosion is interpreted as resulting from the combination of heavy rainfall and snowmelt. The recurrence of flash flood events during the Holocene was, however, not high enough to affect pedogenesis processes and highlight several wet regional periods during the Holocene. The Holocene period is divided into four phases of environmental evolution. Over the first half of the Holocene, a progressive stabilization of the soils present through the catchment of Lake Ledro was associated with a progressive reforestation of the area and only interrupted during the wet 8.2 event when the soil destabilization was particularly important. Lower soil erosion was recorded during the mid-Holocene climatic optimum (8000-4200 cal. yr BP) and associated with higher algal production. Between 4200 and 3100 cal. yr BP, both wetter climate and human activities within the drainage basin drastically increased soil erosion rates. Finally, from 3100 cal. yr BP to the present-day, data suggest increasing and changing human land use.

L’œuvre scientifique de Cyprien Ayer (1825-1884). Grammaire, Pédagogie et Dialectologie

Cyprien Ayer (1825–1888), figure marquante de la vie intellectuelle en Suisse au XIXe siècle, est l'auteur d’une vaste œuvre scientifique, journalistique et littéraire. Parmi ses travaux linguistiques les plus importants il faut mentionner sa Grammaire comparée de la langue française (1876; nombreuses rééditions), sa Phonologie de la langue française (1875), et son Introduction à l’étude des dialectes du pays (1878). Ce dernier texte, ouvrage pionnier dans le domaine des études francoprovençales, est réimprimé ici, précédé d'une introduction. Le présent recueil regroupe des contributions qui concernent l’œuvre linguistique et littéraire d’Ayer et ses rapports avec une autre figure-clef de la vie littéraire et intellectuelle en Suisse, Henri-Frédéric Amiel. Le recueil s’ouvre par une étude de la carrière d’Ayer et par une bibliographie de ses travaux scientifiques (grammaire, dialectologie, pédagogie, économie, géographie, statistique, politique, ethnographie).
