Allestire per rieducare. Un dovere ripensare gli spazi nel carcere.

Il carcere è un mondo chiuso, fossilizzato perché i mutamenti al suo interno avvengono con lentezza; necessita di attenzione non solo in termini di dimensioni degli spazi, ma sul ruolo che i rapporti e le proporzioni degli stessi, gli arredi, i colori, i materiali, le finiture, la luce e l’ombra possono avere sul benessere fisico e psicologico dell’utenza. E’ necessario ripensare l’allestimento degli spazi carcerari in termini di qualità di vita dei detenuti, affinché siano funzionali alla lo...

Scalar mixing in homogeneous isotropic turbulence: A numerical study

The understanding of the mechanics of turbulent dispersion is of primary importance in estimating the effects of mixing processes involved in a variety of events playing a significant role in our daily life. This motivates research on the characterization of statistics and the complex temporal evolution of passive scalars in turbulent flows. A key aspect of these studies is the modeling of the probability density function (PDF) of the passive scalar concentration and the identification of its...

Mass and momentum balance during particle migration in the pressure-driven flow of frictional non-Brownian suspensions

The transient shear-induced particle migration of frictional non-Brownian suspensions is studied using particle-resolved simulations. The numerical method – the fictitious domain method – is well suited to heterogeneous flows thanks to a frame-invariant formulation of the subgrid (lubrication) corrections that does not involve the ambient flow (Orsi et al., J. Comput. Phys., vol. 474, 2023, 111823). The paper aims to give an accurate quantitative picture of the mass and momentum balance durin...

Frame-invariant sub-grid corrections to the Fictitious Domain Method for the simulation of particulate suspensions in nonlinear flows using OpenFOAM

A particle-scale simulation method for non-Brownian suspensions at low Reynolds numbers is presented, which is well suited to nonlinear flows. It is based on a Fictitious Domain Method supplemented by sub-grid corrections. In the original method, the standard sub-grid corrections involve the underlying suspension linear flow. The conditions required to remove this ambient flow from the sub-grid corrections, while keeping frame indifference, are determined. A sub-grid correction matrix is buil...

Cultivated meat beyond bans: Ten remarks from the Italian case toward a reasoned decision-making process

Cultivated meat has become a polarizing topic in the political discourse worldwide. Italy was the first country to pass legislation to ban cellular agriculture products. A thoughtful reflection on this experience reveals the urgent need for rigorous, cross-sectoral research and regulatory diligence for the advancement of the field.
