Le fontane del Quirinale nel Codice Barberiniano Latino 4409
No full textNel saggio vengono analizzati i disegni di Domenico Castelli raffiguranti due fontane del giardino del Quirinale, una, scomparsa, identificabile tramite alcune incisioni del Falda, l'altra tuttora esistente, seppure notevolmente modificata rispetto alla testimonianza del Castelli. Le due opere, così come sono rappresentate nel codice, vengono indagate criticamente nelle loro valenze linguistiche e formali e inquadrate in un più generale discorso sulle architetture di fontane e mostre d'acqua tra la fine del XVI e la prima metà del XVII secolo.
Domenico Castelli’s designs are analysed which illustrated two fountains in the Quirinale gardens, one has disappeared, the other still exists but has been significantly modified. The two works were incorporated into a more general discussion on architecture between the end of the XVIth and the first half of the XVIIth Centuries
Domenico Castelli architetto
No full textNel saggio si procede alla ricostruzione della figura professionale e artistica dell'architetto Domenico Castelli, attivo a Roma in particolare sotto il pontificato di Urbano VIII (1623-1644), con ruoli di diversa importanza in contatto con i maggiori artisti dell'epoca. Grazie a un'approfondita ricerca d'archivio si è redatta una particolareggiata ed esaustiva cronologia della vita e delle opere dell'architetto, confermando alcune attribuzioni e suggerendone di nuove, anche sulla base di un'analisi della specificità del suo linguaggio architettonico. Ci si è inoltre soffermati in particolare, anche attraverso un accurato rilievo, sul complesso del Santuario di Cibona presso Allumiere.
The work rebuilds the figure of the architect Domenico Castelli, who was active in Rome during the time of Pope Urban VIII (1623-1644), by using dating of his activity and a catalogue of his works. The work is completed by a study of the Santuario of Cibona in Allumiere, Lazio
I disegni di Domenico Castelli del codice Barb. lat. 4409 alla Biblioteca Apostolica Vaticana
No full textIl corpus di disegni di D. Castelli (cod. Barb. lat. 4409), contenente l'illustrazione di opere fatte eseguire da Urbano VIII (1623-1644), è stato accuratamente analizzato nella sua composizione e struttura, al fine di una collocazione cronologica all'interno dell'attività del Castelli e, allo stesso tempo, per un'interpretazione del suo valore di fondamentale testimonianza della politica edilizia ed architettonica urbaniana.
The body of designs by Domenico Castelli (code Barb. lat. 4409), is a testimony to the construction and architectural policy of Pope Urban VIII. It is analysed in its structure with the aim of placing it within Castelli’s activities

Considerazioni sulla facciata di S. Bibiana in Roma
No full textGrazie a un accurato rilievo e allo studio delle testimonianze iconografiche contenute nel corpus dei disegni di D. Castelli (cod. Barb. lat. 4409), si è potuto ricostruire con sufficiente sicurezza il progetto originario del Bernini per la facciata della chiesa di S. Bibiana in Roma. Sulla base di tale ricostruzione si è proceduto a una analisi linguistica di questa prima prova architettonica berniniana, evidenziando gli elementi innovativi e trasgressivi di un'architettura finora considerata 'minore' all'interno della più studiata produzione dell'artista.
The work suggests both the reconstruction and the critical interpretation of Bernini’s original construction of the façade of the S. Bibiana church in Rome
Resistant starch in the Italian diet
No full textResistant starch (RS) has been defined as the sum of starch and starch-degradation products that reach the human large intestine (Champ, 1994), and it is now regarded as a sub-fraction of starch with a positive impact on colonic welfare and lipid metabolism. An early estimate of the RS intake in Europe gave an average value of approximately 4 g/d (Dyssler & Hoffem, 1994a). However, since no information is available for Italy, the aim of the present study was to estimate the intake of RS in the Italian diet by direct analysis of RS in a range of typical foods representing the main sources of starch intake in the country. The selection of representative foods and of food consumption data were based on published results of the National Food Consumption Study conducted during the 1980s by the National Institute of Nutrition on 10,000 households, using weighed-food records plus inventory methodologies (Saba et al. 1990; Turrini et al. 1991). Three main groups of foods were considered: cereals (pasta, rice, bread and bread products, and pastries), potatoes, legumes. Different commercial brands for each sample were purchased, according to the known presence on the market. Samples were prepared 'as eaten' and submitted to simulated chewing, followed by total and resistant starch determination using the enzymic procedure published as a result of the EC Concerted Action EURESTA (Champ, 1992). From these results, the estimated average intake of RS in Italy was found to be 8.5 g/d, with regional differences (from 7.2 g/d in the north-west to 9.2 g/d in the south) mainly due to the different consumption of some typical Italian starchy food (bread, pasta, legumes)
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
