摘要: The rheological model is developed to elucidate the mechanism of Ca-alginate microbead deformation in course cell growth within. It a complex process influenced by relaxation expanded polymer network inside bead, and forces generated bead interactions between solvent, parts cells as well. resulting effects are measured experimentally estimating isotropic volumetric deformations beads with yeast function time concentration per bead. mathematical based on modified general Zener fractional derivatives. particularly suitable for incorporating different nature also during stages such development. results theoretical analyses using comparison experimental values obtained, indicate high impact partial decomposition, i.e. plastic response due growth, deformation. For comparison, corresponding measurements modelling were performed same system exposed swelling but without cells. In this case elastic dominant, indicating influence cells, agreement previous conclusions.
