Abstract
The aim of this article is twofold: first, to present and analyze various practices for the finite-volume discretization of the diffusion term in continuum mechanics transport equations; and second, to illustrate the problems that scientific journal editors face with unscrupulous or ignorant contributors and incompetent or simply lazy and indifferent reviewers by analyzing several articles related to the finite-volume approximation of the diffusion term published by a group of authors in various refereed journals.
