Probability Backflow for a Dirac Particle

Foundations of Physics, 1998
The phenomenon of probability backflow, previously quantified for a free nonrelativistic particle, is considered for a free particle obeying Dirac's equation. It is known that probability backflow can occur in the opposite direction to the momentum; that is to say, there exist positive-energy states in which the particle certainly has a positive ...

Pyelo-Renal Backflow

The British Journal of Radiology, 1941
1. The historical and experimental aspects of pyelorenal backflow are reviewed in some detail. 2. Four types of backflow may be recognised, namely pyelovenous, pyelolymphatic, pyelo-interstitial, occurring after calycinie rupture, and pyelotubular which occurs independently of rupture. 3.

INSTALLING BACKFLOW PREVENTERS

Journal AWWA, 1970
The author comments on Mr. William E. West's article entitiled “Auxiliary Water Supplies and Cross‐ Connection Control”, published in the August 1969 Journal AWWA issue (pp. 401‐402). He expresses doubt as to whether the procedures described in the “Current Procedures” section of the paper comply with the California Administrative Code.

Backflow: A Collection

This collection consists of a critical preface and nine essays. The preface analyzes, first, how the imagination influences the personal journey of a writer, and second, the techniques authors use, mainly form, time, and space, to enact the imagination and propel the reader into an imagined narrative.
