Il teatro Donizetti. Metamorfosi della scena urbana a Bergamo
No full textIl volume raccoglie i risultati di una ricerca sulle relazioni tra la città di Bergamo e la sua più rilevante architettura teatrale, condotta dall'autore e da Emanuela Casti, che hanno coordinato due distinti gruppi di ricerca, costituiti presso il Dipartimento di Architettura e Studi Urbani del Politecnico di Milano e il Centro Studi Territorio dell’Università degli Studi di Bergamo.
La ricerca, finanziata dalla Fondazione Teatro Donizetti e da un cittadino bergamasco, è stata condotta mentre i lavori di
restauro e di recupero del Teatro Donizetti erano ancora in corso, con il preciso intento di testimoniare come la vicenda
di questo complesso architettonico, al contempo maestoso e fragile, si sia retta sulla presenza di un cantiere, per molti aspetti, "infinito". Il volume analizza le vicende che hanno accompagnato l’evoluzione della società e della cultura cittadine, documentando la continua sovrapposizione tra scena teatrale e scena urbana. Nell’orizzonte temporale degli ultimi due secoli, il transito del teatro (Riccardi, prima, Donizetti, poi) dentro momenti di crisi ricorrenti rappresenta un formidabile
insegnamento, sul quale, in un'era caratterizzata dagli effetti della pandemia su Bergamo, è valsa la pena ritornare. Nel testo i contributi dell'autore e di Francesca Zanotto, assegnista di ricerca in questo progetto, sono stati dedicati alla ricostruzione delle vicende architettoniche e urbanistiche che hanno caratterizzato il rapporto teatro/città e alla ricognizione sugli archivi della Fondazione, che conservano la documentazione sulle eccezionali scenografie realizzate nell'ambito dell'iniziativa nota come Teatro delle Novità
Towards a theory of interpretation: cartographical semiosis
No full textOver the last 10 years a new theory in the interpretation of cartography has takes shape. In her overview of the various interpretative approaches that have variously contributed to the present critical approach, the author identifies semiotics as one of the trails principally worth pursuing. A semiotic approach, namely a theory of cartographic interpretation, effectively shifts the emphasis from maps intended as mediation of territory to maps takes as agents, whereby actions to be carried out on territory are determined. This perspective may be defined as cartographic hermeneutics, since it undermines the very semiotic notion of map analysis: the study of maps relies not on autonomous semiosis but on a second level (or meta-semiotic) semiosis that is deeply rooted in and strictly related to first-level, territorial semiosis. In particular, the author focuses on two concepts: self-reference and iconization. The former, which constitutes the core of cartographic communication, is used to indicate the map’s ability to be accepted as such (by its mere existence) and to communicate independently of the intentions of the cartographer. The latter is the communicative process that results in circumstances and contingencies being communicated as truths (thanks to the self-referential nature of the map). Hence, as a model, the map does not represent territory but replaces it. Iconization means that direct knowledge of the world is sidelined, with the greater relevance being given to the knowledge generated by the map itself
Cartographic Semiosis: Reality as Representation
No full textOver the last ten years, a new theory in the interpretation of cartography
has taken shape. In her overview of the various interpretative approaches
that have contributed to the present critical approach, the author notably
identifies semiotics. A semiotic approach, and the theory of cartographic
semiosis in particular, effectively shifts the emphasis from maps as a
mediation of territory to maps as agents, whereupon the actions to be
carried out in territory are determined. This perspective may be defined as cartographic hermeneutics, given that it undermines the very semiotic notion of map analysis

Taxonomic remarks on Dianthus sylvestris Wulfen group (Caryophyllaceae) in C-S Italian Peninsula, Sicily and Sardinia
No full textA taxonomic revision of the populations belonging to the Dianthus sylvestris Wulfen group (Caryophyllaceae) occurring
in central and southern Italy, Sardinia and Sicily has been made. This group is represented in the surveyed territories
by 17 morphologically and ecologically well differentiated species: Dianthus arrosti C. Presl, D. siculus C. Presl,
D. graminifolius C. Presl, D. cyathophorus Moris, D. gasparrinii Guss., D. longicaulis Ten., D. virgatus Pasquale, D. tarentinus
Lacaita, D. morisianus Vals., D. japygicus Bianco & Brullo, D. sardous Bacch., Brullo, Casti & Giusso, D. busambrae
Soldano & F. Conti, D. brachycalyx Huet sp. nov., D. oliastrae sp. nov., D. insularis sp. nov., D. genargenteus sp. nov. and
D. ichnusae sp. nov. Besides, two new subspecies are recognized within D. ichnusae (subsp. ichnusae and subsp. toddei).
This taxonomical treatment is supported by a multivariate analysis based on 25 morphological characters and
1 phenological character. Each of the taxa is described and illustrated. In addition, notes on nomenclature, ecology,
chorology, taxonomical relationships and conservation status are given. Lectotypes are designated for those taxa that are
based on material from the investigated territories

Performance Analysis of Thermal Energy Storage (TES) Systems based on Sensible and Latent Heat for Concentrated Solar Power (CSP) Applications
No full textThe research on thermal energy storage (TES) systems carried
out by the Department of Mechanical, Chemical and Materials Engineering
(DIMCM) of the University of Cagliari focuses on sensible and latent heat.
In these last years, several research projects have concerned the
characterization of this kind of TES systems by developing mathematical
models, for simulating and predicting performance, and implementing
laboratory facilities. In particular, the last studies frame mainly in two
research projects. The first one concerns the performance evaluation of a
sensible heat TES system composed of a tank filled with solid beads
(packed bed) crossed by air used as heat transfer fluid (HTF). The second
one aims to compare the performance of latent heat TES systems of
different geometrical configurations. The present paper reports some
results, introduced by a brief description of the technology
Giovan Battista Casti, "Il poema tartaro". Edizione critica e commento.
No full textMy thesis is a critical edition of the Poema tartaro by the libertine abbot Giovan Battista Casti (1724-1803). This work is a long octave poem, which satirizes, in accordance with the rules of the mock-heroic genre, Catherine II’s Russian court, where the author lived for years (1776-1779) as a member of the Hapsburg diplomacy. Although Casti was the Austrian court’s official poet, his work never received the authorization to be printed: the emperor Joseph II, after his 1781 alliance with Russia, forbade in fact the publication of a poem whose theme was explicitly against his new ally. Still, Casti’s text circulated widely in form of both manuscript copies and unauthorised (as well as defective) printed ones. A thorough analysis of these materials led to main findings: the version of the poem that Casti realized for the emperor in 1786, including 84 new stanzas, missing in the nineteenth-century pirate printed editions of the poem.
Along with the critical edition of the text, my thesis provides a broad commentary on the poem. The commentary is essential in order to illustrate the different perspectives from which the text can be approached. Sure enough, one of the components peculiar to the Poema Tartaro is the continuous overlap of elements that draw on different historical moments: even if the main scenery of the plot is the thirteenth-century Mongolian Empire, ruled by Genghis Khan, there are in fact several references to the nineteenth-century Russia of Catherine II. This strategy aims to present Russia allegorically as a country of perennial savagery. Depicting Petersburg as if it were the lost city of Karakorum and the czarina Catherine as a despotic and “oriental” sovereign, Casti contrasts the French Illuminists’ vision (in particular Voltaire’s) of nineteenth-century Russia as a model for the European Enlightenment. The thesis is completed by an index of the different historical transvestisms used by Casti to assign to every character in Catherine’s court a counterpart in the Mongolian scenery. Furthermore, the index is conceived as a tool to analyse the correlated controversies that inform the whole poem
