The HCV Sicily Network: A web-based model for the management of HCV chronic liver diseases
Epidemiological studies report that in Sicily reside about 30,000 citizens with a diagnosis of chronic hepatitis due to HCV. The availability of direct antiviral action (DAA) is a real therapeutic breakthrough, but the high cost of the therapeutic regimes limits their use and forced the National Health System to establish clinical priority for the treatment.The HCV Sicily Network is a web-based model of best medical practice, which was designed to improve the management and the treatment of HCV chronic hepatitis and cirrhosis. The network includes 41 centers and 84 gastroenterologists or infectivologists connected by a web platform that recorder the diagnosis and the clinic priority for the…
A Study on Outdoor and Indoor Climate to satisfy particular Requisites in Museum. The case of the Punic Ship in the Marsala's Archaeological Museum
In the Archaeological Museum in Marsala are keept many archaeological finds discovered in the sea near the city. The most important is the wooden hull of an ancient punic ship found some years ago. The rests of the ship have been submitted to impregnation with PEG, to eliminate the water and the salts absorbed the sea mud, and then is exposed inside a protective awning of plastic material, build up in one of the rooms, in order to contain as much as possible the indoor climatic variations. The responsibles of the museum wants now expose the finds in an free environment in which fixed and steady conditions can be kept. The authors have been requested to study an air condition system that can…
Fisica Tecnica - Vol.I Trasmissiohe del calore - moto dei fluidi
In questo libro sono trattati i fondamenti teorici della trasmissione del calore nei tre modi: conduzione, convezione e irraggiamento. Vengono pure esaminati alcuni problemi specifici che interessano i vari campi dell’Ingegneria civile e industriale: scambiatori di calore, alettature, scambi radiativi col Sole e la volta celeste, materiali isolanti, ecc. Viene poi fatta una trattazione introduttiva dei fondamenti del moto dei fluidi nei tubi con qualche cenno sulle correnti fluide esterne e su quelle di fluidi comprimibili. Il libro nasce dalle esigenze didattiche avvertite dagli Autori nella loro esperienza di docenti nei corsi di laurea in Ingegneria, ma può anche interessare il più vasto…
An experimental investigation on natural convection of air in a vertical channel
Abstract The free convection of air in a vertical channel is studied experimentally in a laboratory model of height H = 2.6 m and rectangular cross-section b × s , with b = 1.2 m and the channel width s variable. One of the channel walls is heated with a uniform heat flux. Tests are made with different values of channel gap and heating power ( s = 7.5, 12.5, 17 cm; q c = 48–317 W m −2 ). On the basis of the results two empirical formulae are found, giving Nu and Re as functions of Ra and the geometrical parameter s/H ; Nu = 0.9282 Ra 0.2035 (s/H) 0.8972 ; Re = 0.5014 Ra 0.3148 (s/H) 0.418 . The mathematical form of these relationships reproduces other previously published formulae, valid fo…
