in which ,4(p+) and B(p*) are some universal functions of the stability parameter p+ . Sometimes A and B appear interchanged and p = k ~ +
is used as
a stability parameter, although unnecessary use of the Von Karman constant is becoming a problem in view of the recent controversy about its exact
value.
