Nagetier-Territorien und -Wechsel, the largest single hydraulic cause of pipeline failure. It is strange, therefore, to find that a large percentage of users are not aware of the danger to their pipelines caused by rapid velocity fluctuations, nor do they seem particularly interested in studying the considerable volume of literature that now exists on this subject.

Ward Identities for Conformal Models,invariance is invoked, but mostly, locally holomorphic coordinate transformations are used.., in clash with the locality principles of all known versions of quantum field theory. Diffeomorphism invariance is on the other hand understood in terms of Riemannian geometry, but not directly in terms of c
