The same figures are reported here.
The main conclusions of this analysis of forecast, with the Verhulst logistic equation are:
- The decrease of the total infections, still in progress, forecasted after the maximum of April 20th, is
confirmed.
- The decrease of the new infections, forecasted at the beginning of April, is confirmed.
- The decrease of the new deaths, forecasted at the beginning of April, is confirmed
The main use of these analyses are:
An eventual increase of the total and new infections and of the new deaths, can be promptly
monitored by the employment of this approach.Update of May 21th

Un egiziano nel Paese di Retjenu. Geografia e percorsi identitari nel Racconto di Sinuhe tra spazi reali e letterari
No full textIl Racconto di Sinuhe è sicuramente uno dei prodotti più noti e raffinati della letteratura egiziana del Medio Regno. Caratterizzata da una struttura e da un’articolazione narrativa complesse, l’opera si presenta come “a tale of adventure in foreign lands” (Parkinson, The Tale of Sinuhe, 21), incentrata
sulla fuga del protagonista (Sinuhe) dall’Egitto e sull’esperienza di allontanamento e distacco che egli, viaggiatore ed esule suo malgrado, vive nel paese asiatico di Retjenu. Da questo punto di vista, il racconto offre una testimonianza interessante non soltanto della geografia e della natura dei
contatti tra Egitto e Levante agli inizi del II millennio a.C. ma, soprattutto, di come tali rapporti fossero percepiti, rappresentati e comunicati in ambito egiziano.
Il contributo si propone dunque di esaminare le modalità di costruzione di questo scambio in termini di polarizzazione identità ↔ alterità culturale all’interno del discorso letterario dell’opera, al fine di illustrare gli schemi percettivi, le pratiche sociali e le rappresentazioni simboliche soggiacenti all’orizzonte geografico e alla strutturazione gerarchica dei rapporti tra le parti in gioco
On a new turbulent energy equation with variable thermal conductivity
No full textThe present work investigates the energy equation of a general fluid, Newtonian or non-Newtonian, with variable thermal conductivity in turbulent flow. The usual energy equation, without the dissipation terms, is taken into account with the fluctuating terms in the temperature as well as in the thermal conductivity. The energy equation is written for the average temperature, for the fluctuating temperature one as well as for the square of the fluctuating temperature. Besides the usual Reynolds stresses, a new term appears, which is the product of the fluctuation of the thermal conductivity and the gradient of the temperature fluctuation. This new term is interpreted and introduced in the energy equation where the variable is the square of the temperature fluctuation where new terms appear. A possible physical interpretation is given to the different terms. Assuming a polynomial relation between thermal conductivity and temperature it is then possible to write an expression for the average and the fluctuating thermal conductivity. The expressions are then simplified on the basis of physical and mathematical considerations. Specifically, the heat flux due to the fluctuating thermal conductivity is then expressed as the product of the derivative of the thermal conductivity with the mean temperature to the gradient of the square of the temperature fluctuation. Further considerations allow to write a new energy equation of the average temperature which include the new term. The solution of this energy equation is possible with the coupled solution of the equation for the square of the fluctuating temperature. The introduction of this new term in the energy equation can be of some importance in problems related to liquid metals flowing in turbulent flow and/or in very low temperature applications where the thermal conductivity becomes very high.</p
Numerical Simulation of Blood Flow through Different Stents in Stenosed and non-Stenosed Vessels
Full text linkThe fluid dynamics in two different stent configurations, peak-to-valley (S1) and peak-to-peak (S2),
within a fully expanded situation and a 30% restenosis, is investigated. Numerical simulations are
carried out in order to evaluate the conditions promoting atherosclerotic events when a selfexpanding
bare metal stents (SE-BMS) is applied. The conclusions are that the two configurations,
S1 and S2, have a similar fluid dynamic behavior, as far as the WSS is concerned, but OSI and RRT
maps suggest that the peak-to-peak configuration, S2, has a better behavior than the peak-to-valley
one, S1
