    • We note that L. Slade and H. Levine, (in The Glassy State in Foods, ed. J. M. V. Blanshard and P. J. Lillford, Nottingham University Press, Loughborough, U.K., 1993, pp. 3-101) published a comparable result based on the recognition of the mathematical form (rectangular hyperbola) of the WLF equation, though they did not connect it to the equation (3) vibrational pre-exponent. Similar remarks apply to the graphic analysis of the WLF equation in the monograph of Donth. Slade and Levine further point out the relation of the WLF equation to the Michaelis-Menton equation, which is widely used in the description of enzyme reaction kinetics.
