L'Arena Flegrea: rivitalizzazione e riaulificazione di un monumento - teatro
No full text“... Accanto alla vegetazione ed agli aspetti sereni e lieti della natura, qual è tutto l’amenissimo lido di Pozzuoli e di Baia, il cratere ribollente della Solfatara, la plumbea pesantezza delle acque del lago d’Averno, le caverne o le spelonche sacre al culto dell’invisibile, agli spiriti ed alle voci del mistero...” negli anni Trenta venne realizzato il più grande teatro d’Europa dell’epoca, capace di ospitare diecimila spettatori: l’Arena Flegrea. L’obiettivo del nostro studio è quello di evidenziare sia le caratteristiche formali, tecnologiche e materiche dell’impianto originario dell’Arena, che si integrava in maniera ottimale nello spazio naturale in cui sorgeva, magistralmente descritto da A. Maiuri, sia le scelte progettuali di G. De Luca, che recentemente ha recuperato e rivitalizzato l’antico teatro. L’Arena, realizzata tra il 1938 ed il 1940, fu inaugurata poco prima dell’inizio della II guerra mondiale. Praticamente distrutta a seguito degli eventi bellici, negli anni cinquanta fu oggetto di un attento intervento di ristrutturazione, ma abbandonata al degrado e ulteriormente danneggiata per l’occupazione dei senzatetto del terremoto del 1980, è sopravvissuta come rudere fino alla fine del secolo quando De Luca, chiamato per recuperare questo grandioso monumento-teatro, con grande coraggio decide di procedere alla demolizione dei resti dell’opera per riproporre l’Arena in chiave moderna ma rispettosa degli stilemi originari
Hypercalcaemia in systemic lupus erythematosus.
No full textHypercalcaemia is found in more than 90% of the cases of primitive hyperparathyroidism and malignancies. Rarely, D hypervitaminosis, sarcoidosis, other granulomatous diseases, some drugs, and endocrine diseases may be responsible. Nine patients with systemic lupus erythematosus (SLE) and hypercalcaemia, without evidence of primary hyperparathyroidism, have been previously described. Here we report the 10th patient with SLE and hypercalcaemia, along with a brief review of the literature. © 2011 The Author(s)
Porto Flavia: an "iconic" engineering work in the mine machine-landscape
No full text“The new triumph arising from National industry”. These were the words with which Porto Flavia was presented in the magazine “La Miniera Italiana” [The Italian Mine] in 1926, an extremely modern structure overlooking the sea that revolutionised the ore transportation system from the coasts of the Sulcis Iglesiente (an historical region in Sardinia). The project was designed by Cesare Vecelli in 1921 with the aim of creating a single embarkation point for the mines that were acquired by the Société des Mines et Fonderies de Zinc de la Vieille-Montagne, while the inauguration dates back to 1924. Porto Flavia is therefore the gateway to the sea of a dense and complex infrastructure network that allowed the transportation of ore from the innermost deposits to the coastal ones in Masua, along roads, railway routes and extremely long inclined planes served by modern funicular structures. The original idea was prompted by a rock spur overlooking the sea, inside which two tunnels were dug out: the top one with the mouth upstream and the bottom one with the outlet onto the sea. The two tunnels were separated by a difference in height of 20 metres where nine large storage silos were dug. During the loading operation, a mechanical cantilever arm poured the ore directly over the sea inside the hold of steamships. Porto Flavia is today one of the most significant and iconic mining-archaeology landscape structures on the coast of the Sulcis-Iglesiente: a Neoclassical façade, almost metaphysical, embedded in the cliff which frames the mechanical arm and conceals the ingenious internal gear, while the plastered surface hides a skilful blend of natural materials and elements derived from the mining production, such as reinforced concrete and the rails of the track. The recovery of this abandoned architecture could become the occasion for repairing, with new paradigms, the rich fabric of relations between the landscapes of the mining archaeology and those of the coastline, with an integrated model capable of creating a new development based on cultural and tourist uses
La disponibilità a pagare e le preferenze dei turisti per i siti del Parco Geominerario della Sardegna: il caso di Porto Flavia
No full textQuesto lavoro presenta alcuni risultati di uno studio di valutazione contingente, condotto al fine di stimare il valore turistico di Porto Flavia - un sito fra i più interessanti del Parco Geominerario recentemente istituito in Sardegna sotto il patrocinio dell’UNESCO. Dopo aver discusso il ruolo che adeguate politiche di gestione dei beni culturali ed ambientali possono assumere per garantire uno sviluppo turistico sostenibile, descriviamo le principali caratteristiche del metodo, la struttura dell’indagine ed i dati ottenuti. L’analisi dei dati si concentra sulla stima della disponibilità a pagare e del flusso turistico potenziale. Sono identificati possibili obiettivi d’intervento per la valorizzazione del percorso esistente ed una gamma di prezzi per diverse opzioni di offerta turistica.

Monocyte subsets, stanford-A acute aortic dissection, and carotid srtery stenosis. new evidences
No full textMonocytes are a heterogeneous cell population distinguished into three subsets with distinctive phenotypic and functional properties: "classical" (CD14++CD16-), "intermediate" (CD14++CD16+), and "nonclassical" (CD14+CD16++). Monocyte subsets play a pivotal role in many inflammatory systemic diseases including atherosclerosis (ATS). Only a low number of studies evaluated monocyte behavior in patients affected by cardiovascular diseases, and data about their role in acute aortic dissection (AAD) are lacking. Thus, the aim of this study was to investigate CD14++CD16-, CD14++CD16+, and CD14+CD16++ cells in patients with Stanford-A AAD and in patients with carotid artery stenosis (CAS). Methods. 20 patients with carotid artery stenosis (CAS group), 17 patients with Stanford-A AAD (AAD group), and 17 subjects with traditional cardiovascular risk factors (RF group) were enrolled. Monocyte subset frequency was determined by flow cytometry. Results. Classical monocytes were significantly increased in the AAD group versus CAS and RF groups, whereas intermediate monocytes were significantly decreased in the AAD group versus CAS and RF groups. Conclusions. Results of this study identify in AAD patients a peculiar monocyte array that can partly explain depletion of T CD4+ lymphocyte subpopulations observed in patients affected by AAD.Monocytes are a heterogeneous cell population distinguished into three subsets with distinctive phenotypic and functional properties: classical (CD14++CD16-), intermediate (CD14++CD16+), and nonclassical (CD14+CD16++).
