Recent analysis has demonstrated that there's a pre and write-up-breakdown regime from the around-wall boundary layer in which the sublayer thickens in a declining amount and then abruptly undergoes a breakdown into turbulent vortices right before at last collapsing. This system is totally self-regulating and mediates the growth and decay cycle; the vortices accumulate all through the growth period of time and they are abruptly liquidated into Strouhal arrays of hairpin vortices lifting from the wall.
The thickness of scales increases as new, larger sized scales expand beneath the aged ones. The rings are located a lot less and thicker, making broader and narrower regions. The quantity of scleritis zones fashioned every year corresponds to your age in the fish.
