| الوصف: | Diffusion equation with a fractional Caputo time derivative with respect to another function $g$, which defines new time scale of the process, is applied to describe anomalous diffusion of antibiotic (colistin) in a system consisting of packed gel (alginate) beads immersed in water and impregnated with the antibiotic. We show that ultraslow diffusion of colistin in the system occurs. The equation, which is more general than the "ordinary" fractional subdiffusion equation, can be widely used in various fields of science to model diffusion in a matrix with channels system when subdiffusion parameters and even a type of diffusion evolves over time. Comment: 8 pages, 6 figures |
