Article
Full-text available
Orbital shakers are simple devices that provide mixing, aeration, and shear stress at multiple scales and high throughput. For this reason, they are extensively used in a wide range of applications from protein production to bacterial biofilms and endothelial cell experiments. This study focuses on the behaviour of orbitally shaken shallow fluid la...

A new model for the analytical prediction of wall shear stress distributions at the base of orbitally shaken shallow fluid layers is developed. This model is a generalisation of the classical extended Stokes solution and will be referred to as the potential theory-Stokes model. The model is validated using a large set of numerical simulations cover...
Article
Transport of macromolecules across vascular endothelium and its modification by fluid mechanical forces are important for normal tissue function and in the development of atherosclerosis. However, the routes by which macromolecules cross endothelium, the hemodynamic stresses that maintain endothelial physiology or trigger arterial disease, and the...

We introduce a new model for the spectral energy distribution of galaxies, GRASIL-3D, which includes a careful modelling of the dust component of the interstellar medium. GRASIL-3D is an entirely new model based on the formalism of an existing and widely applied spectrophotometric model, GRASIL, but specifically designed to be interfaced with galax...

Galaxies formed in cosmological simulations have been identified at different environments, either isolated or in groups. We have made a study of massive galaxy properties at different redshifts, to try to understand how the environment affects them at different epochs of their assembly and/or evolution.
Article
Isolated galaxies and groups of galaxies have been identified in a cosmological simulation at z = 0, as well as their progenitors at higher zs. We discuss the physical processes underlying their assembly and in particular the role law and chance could have played.
