Turbulent heat transfer in spacer-filled channels: Experimental and computational study and selection of turbulence models

2019

Abstract Heat transfer in spacer-filled channels of the kind used in Membrane Distillation was studied in the Reynolds number range 100–2000, encompassing both steady laminar and early-turbulent flow conditions. Experimental data, including distributions of the local heat transfer coefficient h, were obtained by Liquid Crystal Thermography and Digital Image Processing. Alternative turbulence models, both of first order (k-e, RNG k-e, k-ω, BSL k-ω, SST k-ω) and of second order (LRR RS, SSG RS, ω RS, BSL RS), were tested for their ability to predict measured distributions and mean values of h. The best agreement with the experimental results was provided by first-order ω-based models able to …

Gli spettri, il conforto della letteratura e l’autenticità del reale nell’esperienza concentrazionaria di Charlotte Delbo

2020

The Holocaust literature transforms many narrative categories in an attempt to find forms capable of conveying the historical experience of extermination. As an alternative to the impossible mimetic reproduction of reality, many authors resort to the imaginary and its rhetorical and narrative devices to reconstruct the concentrationary experience. The essay aims to trace the forms and functions of phantasmagoria in some texts by Charlotte Delbo where the transfiguration of reality makes the process of remembrance possible and, at the same time, the recomposition of the subject.

Effect of family structure and TPH2 G-703T on the stability of dysregulation profile throughout adolescence

2015

Abstract Background Two different polymorphisms (TPH2 G-703T and 5-HTTLPR) involved in the serotonergic pathway have been reported to play a role, both alone and in interaction with the environment, in early and adult emotion regulation. As most of these studies are cross-sectional, we know little about the impact of these polymorphisms over time, particularly during adolescence. Methods Because we were interested in the effects of these polymorphisms and environment (i.e., family structure) at different time-points on the emotional dysregulation profile, we performed a path analysis model in a general adolescent population sample of a five-year follow-up study. Results We found a high stab…

Single tube real time PCR for detection of Streptococcus pneumoniae, Mycoplasma pneumoniae, Chlamydophila pneumoniae and Legionella pneumophila from …

2012

We designed a multiplex real time PCR for rapid, sensitive and specific detection of Streptococcus pneumoniae, Legionella pneumophila, Chlamydophila pneumoniae and Mycoplasma pneumoniae. The study cases consisted of 129 patients with community acquired pneumonia (CAP). Bacteriological techniques were implemented for detection of the cultivable organisms. DNA were extracted from sputa, throat swabs, bronchoalveolar lavages and tracheal aspirates and used as templates in real time PCR. The primers and probes were designed for cbpA (S. pneumoniae), p1adhesin (M. pneumoniae), mip (L. pneumophila) and ompA (C. pneumoniae). After optimization of real time PCR for every organism, the experiments w…

Relazione tra disfunzione erettile, livelli di testosterone e funzione endoteliale in pazienti a rischio cardiovascolare intermedio secondo le stime …

2014

Scopo del lavoro Il ruolo dei livelli di testosterone plasmatico e della disfunzione erettile come marcatori precoci di disfunzione endoteliale non è ben definito. Pertanto, abbiamo cercato di analizzare la relazione tra testosterone plasmatico e disfunzione erettile, in rapporto alla funzione endoteliale. Materiali e metodi Abbiamo quindi arruolato 802 pazienti in prevenzione primaria, con una stima di rischio cardiovascolare (CV) intermedio secondo la carta del rischio di Framingham, di età compresa fra 40 e 80 anni, che si sono sottoposti all’esame ecografico della dilatazione flusso mediata dell’arteria brachiale destra, alla valutazione della disfunzione erettile attraverso il question…

Central obesity and hypertension: Pathophysiologic role of renal haemodynamics and function

1995

OBJECTIVE: To investigate the role of alterations in renal haemodynamics and function and in plasma renin activity on obesity-induced hypertension. DESIGN: Renal haemodynamics and function, salt-regulating hormones and structural cardiac parameters were evaluated in 20 lean normotensives and in 64 obese subjects with central or peripheral fat distribution, 43 of them were normotensives and 21 of them were hypertensives. Obesity and central fat distribution were defined according to sex-specific 85th percentile respectively of Body Mass Index (BMI) and Waist to Hip Ratio (WHR). MEASUREMENTS: Serum immunoreactive insulin (IRI), plasma renin activity (PRA), plasma aldosterone (PA), microalbumi…

Diffusion modeling of COVID-19 under lockdown

2021

Viral immune evasion by sequence variation is a significant barrier to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine design and coronavirus disease-2019 diffusion under lockdown are unpredictable with subsequent waves. Our group has developed a computational model rooted in physics to address this challenge, aiming to predict the fitness landscape of SARS-CoV-2 diffusion using a variant of the bidimensional Ising model (2DIMV) connected seasonally. The 2DIMV works in a closed system composed of limited interaction subjects and conditioned by only temperature changes. Markov chain Monte Carlo method shows that an increase in temperature implicates reduced virus diffusi…
