Heat Transfer Through a Porous Medium
... So far we have been discussing the case of an isotropic medium, for which the conductivity is a scalar. For an anisotropic medium km will be a second-order tensor. Lee and Yang (1998) modeled a heterogeneous anisotropic porous medium. A fundamental issue has been raised by Merrikh et al. (2002, 2005 ...

Estimation of Atomic Mass from Specific Heat Data
... Before the development of mass spectrometry, it was difficult to determine the atomic mass of an element. In 1819, Dulong and Petit discovered that the product (about 26.4) of the atomic mass and the specific heat was nearly the same for many solid elements. This approximation has been found to be v ...
