This is confirmed by the literature on this subject, which disagrees about the effect of high liquid viscosity on gas holdup in bubble columns (Bukur and Patel, 1989 and Syaiful et al., 1990). The following power law function, already proposed by, eg, Godbole et al. ...

The distribution of the various liquid hold up between baskets and corrugated sheets is quantified.

In three dimensions, cells have the ability to communicate and organize into complex architectures similar to those found in their natural environments. The aim of this study was to evaluate, in terms of cell reactivity, a new in vitro cell model: dental pulp stem cells (DPSCs) in a 3D polymeric textile. Scaffolds were knitted from polyglycolic acid (PGA) or polydioxanone (PDO) fibers differing in surface roughness. To promote cell adhesion, these hydrophobic fabrics were also functionalized with either chitosan or the peptide arginine-glycine-aspartic acid (RGD). Cell behavior was examined 1, 10, and 21 days post-seeding with a LIVE/DEAD(®) Kit. Confocal laser scanning microscopy (CLSM) highlighted the biocompatibility of these materials (cell survival rate: 94% to 100%). Fiber roughness was found to influence cell adhesion an...
