Solution of the coupled-mode equations in terms of redefined even- and odd-mode waves
The recently introduced new definition of the fundamental even- and odd-mode waves for nonsymmetrical parallel coupled lines in nonhomogeneous media is proved to verify the coupled-mode form of the differential wave equations under only one restriction, defined as the condition of congruent nonsymmetry.
Abstract The difference spectrum of oxidized enzyme minus d -lactate-reduced enzyme reveals the characteristic absorption bands of an oxidized flavin bound to the protein. The wavelengths of the peaks are: 455 mμ and 385 mμ. The oxidation-reduction potential of the FAD bound to the d -lactate dehydrogenase ( d -2-hydroxyacid: (acceptor) oxydoreductase) of anaerobic yeast has been determined. A spectrophotometric study of the equilibrium between the flavin group and the d -lactate-pyruvate system gives values of E mF = −0.178 Volt at pH7.0 and 30°. The pH-dependence coefficient of this potential is ΔE mF / Δ pH = −0.03 V.
