p.2 l.37: this is the first time that the quantity μ appears, while it has not been introduced yet. p.4 l.21 Total chirality is defined only later (in Eq. 16). p.10 Eq. (20): is this equation correct for non-uniform ρ? p.10 l.15 effected → affected. p.11 caption of Fig. 11: verses → versus. p.11 l.53: this Reynolds number is the _magnetic_ Reynolds number. p.12 3.3.2: the first reference to Fig. 9 seems rather to be a reference to Fig. 8 (time evolution of Υ and ReM). p.14 caption of Fig.10: vertical bars → horizontal bars p.15 Eq. (25): g_{100} is not introduced. p.16 l.30: the reference to Eq. (34) (the next equation) is probably wrong. p.16 l.59: "Υ, the square root of which is the ratio ..." → "Υ, the square root of the ratio ..."
