Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our ... En savoir plus

This research deals with the design of suitable microreactors for the catalytic oxidation of volatile organic compound (VOCs), using propane as a model molecule. The microreactor considered consists of eleven parallel channels, in which an Au/Cr/γ-Al2O3-catalyzed combustion reaction ... En savoir plus

In ground-coupled heat pumps (GCHPs) the coupling between heat pumps and ground occurs by means of ground heat exchangers, that can be installed vertically inside boreholes (BHEs) or horizontally (HGHEs). In the horizontal installation, the heat exchangers are placed in shallow trenches ... En savoir plus

Flow channel design in a PEM fuel cell plays a critical role for uniformly distributing reactants to the reaction sites and effectively removing product water to prevent flooding. Simplistic design and uniform reactant distribution make parallel channels a potential candidate for ... En savoir plus

In this study we evaluate transport, retention and subsistence of Escherichia coli (E. coli), a common fecal indicator bacteria, in a model (2x1m) of a constructed wetland. Transport occurs in the unsaturated and saturated zone. Inactivation is accounted for as a kinetic first-order ... En savoir plus

The flow of electrically conducting fluids such as liquid metals is significantly affected by applied electric and magnetic fields. The effect has important industrial applications in metallurgy, nuclear technology and other fields. This paper described results of a series of studies ... En savoir plus

Concentrated photovoltaic systems with high efficiency solar cells are being widely investigated, aiming at improving the cost-efficiency balance in the solar energy field. Different cell types are in use: e.g., high concentration triple junction cells, reaching efficiencies of the order ... En savoir plus

When a less viscous fluid displaces a more viscous one in a porous medium or Hele-Shaw cell, the interface between the two miscible fluids does not remain flat and deforms into fingers growing in time [1]. It occurs due to the faster movement of less viscous fluid than the more viscous ... En savoir plus

The present study investigates simulation model and droplet ejection performance of a thermal-bubble microejector. This model simulates the bubble nucleation and the bubble growth, to predict the droplet ejection process. Specificity, it is achieved by coupling an electric-thermal model ... En savoir plus

Constitutive properties of living cells are able to withstand physiological environment as well as mechanical stimuli occurring within and outside the body. We examined fluid flow and Neo-Hookean deformation related to the rolling effect. A mechanical model to describe the cellular ... En savoir plus
