La ‘Guida metodica di Roma e suoi Contorni.’ Il viaggio erudito ai Castelli Romani del Cav. Giuseppe Melchiorri, Presidente del Museo Capitolino
This essay describes the journey of Giuseppe Melchiorri, President of the Capitoline Museum, in the area of Castelli Romani
“L’area dell’Augusteo al 1871: riprogettazione del tessuto urbano demolito”, tesi di Laurea Magistrale di Maria Chiara Castellucci e Letizia Romani, a.a.2019-2020, relatore Francesca Geremia. Classificata al secondo posto del III Premio Giovani SIRA 2021.
Lo studio mira a ricostruire virtualmente l’immagine dell’area attorno al Mausoleo di Augusto al 1871. Durante il Fascismo, la liberazione del Mausoleo ha portato alla distruzione degli edifici attorno ad esso, rendendo impossibile la lettura dell’evoluzione urbana dell’area.
Il materiale acquisito durante la ricerca archivistica è stato ordinato a mezzo di un G.I.S. e analizzato sulla base della Terza Stesura del Catasto Gregoriano. La ricerca ha permesso di produrre degli elaborati bidimensionali che mostrano un’immagine realistica di questo brano di città non più esistente. Infine si è elaborato un modello tridimensionale percorribile ai fini della comunicazione della ricerca scientifica

The ontologization of Romani: An Italian study on thecross-categorization approach
This research aims to study the ontologization process of the Romani minority in Abruzzoregion (Italy), characterized by the longstanding presence of a group of sedentary Romani,and to test the cross-categorization approach using a specific dependent measure such asthe ontologization of the Italian Romani target. A questionnaire was administered to 475Italian participants, in which the respondents were asked to attribute 6 human positive, 6human negative, 6 animal positive and 6 animal negative associates to three targets: Italians(ingroup), Italian Romani (ingroup–outgroup) and Romani (outgroup). Participants showedevidence that they used human/animal associates differently for the ingroup and for theoutgroup members. Romani groups were ascribed more animal than human characteristics,while Italians were described as more human than the Romani and Italian Romani group,showing the ontologization process of the Romani minority and the superhumanizationof the Italian ingroup. Moreover, the cross-categorized Italian Romani target was the mostdiscriminated against in that it was attributed more animal negative associates than theRomani and Italian ones. Since modern racism could take the form of the denial of thehumanness and the attribution of animality to outgroup members, our data emphasize theimportance of taking account of the persistence of negative attitudes so deep-rooted asthose felt towards the Romani

Chiara Lubich, Meditazioni: letteratura come relazione
Chiara Lubich (1920–2008), although the author of 32 books published in 26 countries (178 editions, 3.2 million copies), is better known for her social engagement, as reflected in numerous awards. She began to be regarded as a literary author only in the early 2000s, and primarily from a linguistic rather than literary perspective. This article focuses on her book Meditazioni (Meditations), reconstructs its genesis by tracing the writing process from the late 1950s to her death and the 2021 critical edition, and offers a literary analysis. This reveals Lubich as a forerunner of a new conception of literature: literature as relationship – not only between author and reader, but also among subject, inspiration, and the editorial process
Roma vista dai romani. Immagini della Città Eterna nell’Archivio della famiglia Gnoli
Nel fondo privato della famiglia Gnoli sono conservati scritti inediti e illustrazioni che attestano la convinzione da parte degli Gnoli – Tommaso (1797-1874), Teresa (1833-1886) e Domenico (1838-1915) – che Roma abbia un ruolo di primo piano nel processo risorgimentale in corso. Questa si basa sia sulla storia antica della città, testimoniata da monumenti e opere artistiche che la arricchiscono di un valore aggiunto, sia sulla funzione assunta dai romani nei moti. Il contributo indaga entro quali termini l’immagine di Roma assuma, anche per i suoi stessi abitanti, un ruolo nodale nella costruzione dell’identità nazionale prendendo ad esempio il caso dei tre Gnoli
Numerical modeling of heat and mass transfer during coffee roasting process
In this work a numerical model, based on a 3D geometry, able to describe the heat and moisture transfer inside a coffee bean during the roasting process, was developed. The model makes reference to a rotating cylinder roaster in natural convection conditions.
For the multiphysics model development heat and mass transfer equations inside the coffee bean were numerically solved using a finite element technique. Two domain geometries were tested. One simplified, based on a simple semi-ellipsis, and one made acquiring the shape of an Arabica coffee bean using a 3D scanner. To validate the numerical model, green coffee bean was singularly roasted using a rotating drum roasters prototype. The calculated moisture concentration and time–temperature curves were then compared with the observed data.
The calculated temperature values, in the centre of the bean, appear to be in good agreement with those measured inserting thermocouples into the coffee bean (RMSE 5.97 °C). Similarly the calculated volume averaged moisture was in good agreement with the experimental data (RMSE 264.251 mol/m3) over the entire time span. This model can be useful to optimise the roasting process control
Photophysical properties of alizarin and purpurin Al(III) complexes in solution and in solid state
The present study was undertaken to investigate the photophysical properties of the organic-metal compounds which are the main components of madder lake, one of the most commonly used and widespread organic pigments in painted artworks, from both geographic and historic points of view. Alizarin- and purpurin-Al(III) complexes were studied in solution and as powders. In solution, the chelate stoichiometry, their absorption and emission properties and the efficiency of their excited electronic state deactivation pathways have been determined. The two organic-metal compounds show relevant differences in terms of spectral features consisting of multiple peak (structured) absorption and emission spectra for the purpurin derivative and single broad bands (structureless) for the Al(III)-alizarin chelate. For both the investigated molecules, the chelation process induces a relevant increase of the emission quantum yields and lifetimes. The main differences between photophysical properties of the two metal complexes concern emission quantum yield and lifetime, which are both higher for purpurin chelate compared to alizarine chelate. Furthermore, interesting differences between the two metal complexes concerning the relative relevance of inter- and intra-molecular interaction involved in the mechanism of the excitation energy dissipation have been also highlighted. The knowledge of the determined parameters allows better understanding of the spectral behaviour in the solid state, thus providing a solid reference for the non-invasive characterisation and identification of madder lake on original artworks through its absorption and emission features
