WebbNevertheless, from a theoretical point of view, assuming a “universal” definition of the propagon mean free path is questionable. Strictly speaking, ... Nonetheless, at the melting point, where the coaxial cylinder technique occasionally provides reliable data, the present model’s predicted results agree with Creffield and Wickens (1975). WebbThis makes practical sense because there are two different substances. Even though they have the same theoretical melting point, since there are two difference substances, the melting point range would be much wider because the heat distribution takes a long time to spread out when there is a hybrid mixture due to differing size of molecules.
Webbchemical, information theory, as well biomaterials point of view. Since Dictyostelium DNA begins melting as early as the poly (dA.dT) marker DNA added to the melt as an internal standard, one may ask whether the melting of this unusual base composition genome can be accurately described by theoretical methods.
