WebIntroduction. Aerobic bacteria often live in thin fluid layers near solid–air–water contact lines. In order to describe the dynamics of the cell concentration n, oxygen concentration c and fluid velocity u, Tuval et al. [1] proposed a mathematical model n t + u ⋅ ∇ n = Δ n − ∇ ⋅ (n χ (c) ∇ c), c t + u ⋅ ∇ c = Δ c − n f (c), u t + κ (u ⋅ ∇) u = Δ u + ∇ P + n ∇ ... WebSpecifically, a second result asserts, within a suitable topological setting, the existence of a bounded set which eventually absorbs each individual of the obtained trajectories, and the diameter of which is bounded only by the physically relevant quantities of total population size and prescribed boundary concentration of the chemical signal. freightliner alternator pulley
