Conversazione con Vittorino Andreoli
No full textIlario Fioravanti. Architettura come Arte intende esplorare l’opera dell’architetto cesenate Ilario Fioravanti (1922–2012) che, con le sue architetture e le sue opere d’arte, ha saputo comprendere e integrare la natura del territorio e delle città romagnole impiegando i materiali da costruzione come strumento per progettare edifici dotati di carattere, mai eccessivi e mai banali, e sculture in grado di dialogare con il paesaggio circostante. L'intervista intende indagare la relazione che sussisteva tra discipline artistiche e arte architettura all'origine dell'opera di Fioravanti attraverso un confonto critico con il prof. Vittorino Andreoli
Assessment of body hydration in subjects with schistosomiasis
No full textTotal body water (TBW) was measured by deuterium oxide dilution (D2O) and predicted by bioelectric impedance analysis (BIA) (Deurenberg, Schouten, Andreoli and De Lorenzo 1993) in 21 subjects with Schistosoma mansoni infection and 17 healthy controls of similar age (32.8 +/- 13.7 years, n=38). Patients were selected to have no visible fluid retention and no cardiac or renal abnormalities. Body hydration (TBW per kg of body weight) was significantly higher in patients with schistosomiasis than in controls (62.9 +/- 3.6 vs 57.4 +/- 4.3%, p < 0.0005). A significant correlation was found between albumin levels and TBW% on the pooled sample (n=38; r=0.660, p < 0.0001). This relationship was not influenced by the presence of disease, as determined by ANCOVA. Values of TBW predicted by BIA were highly correlated and not significantly different (p=n.s., ANOVA) from those measured by D2O in both controls and patients (r=0.854, p < 0.001, SEE = 2.3 1, CV=5.9% and r=0.848, p < 0.001, SEE=4.0 1, CV=9.3%, respectively). The bias (TBW by BIA - TBW by D2O) was of 0.9 +/- 3.7 in controls and of -1.3 +/- 4.2 1 in patients. This bias was significantly correlated to TBW% in patients (r=0.575, p < 0.05) but not in controls (p=n.s.). It is concluded that subjects with schistosomiasis show an apparent subclinical increase in body hydration which could affect the prediction of TBW from BIA

Evaluation of the uncertainty associated with the ion recombination correction in high dose-per-pulse electron beam dosimetry: An MC approach
No full textThe high dose and dose-per-pulse rates (up to 130 mGy/pulse) produced by some intraoperative radiation therapy (IORT) accelerators pose specific dosimetric problems due to the high density of electric charge per pulse produced in the ionization chamber cavity. In particular, the correction factor for ion recombination, ks, calculated with the traditional two-voltage method is significantly overestimated and three alternative models have been proposed in the literature allowing for the presence of a free-electron component. However, at present there is no general consensus on the best model to assess the ion recombination correction and controversy remains on the uncertainty associated with k s. In the present work we adopted a Monte Carlo (MC) approach to assess the uncertainty associated with the ion recombination correction in plane-parallel chambers used in high dose-per-pulse electron beam dosimetry. The uncertainty associated with k s was calculated for the following plane-parallel ionization chambers: Scanditronix/Wellhofer Parallel Plate Chamber PPC05 and PPC40, PTW Advanced Markus Model 34 045 and PTW Roos Model 34 001. Input variables for MC calculations were derived from experimental data at 28 and 73 mGy/pulse. Taken together, the results of this study indicate that ks values calculated according to the three ion recombination models do not overlap within their standard uncertainties, suggesting that an additional type-B uncertainty component would be necessary to take into account possible differences between the models. Our results indicate that the combined relative standard uncertainty in k s should be calculated as the sum in quadrature of a (type-A) MC-based uncertainty component and a (type-B) uncertainty contribution evaluated assuming a uniform distribution between k s values obtained from the two extreme models
