Esthetic and adhesive properties of a novel colored fiber post: A restorative approach to an endodontic challenge

European Journal of Oral Sciences, EarlyView.
Abstract Colored fiber posts facilitate clinical retrieval but could impact esthetics and bonding. This study evaluated the color stability and dentin bond strength of a novel colored fiber post designed to facilitate post‐removal. Sixty premolars had root canal therapy and post space preparation.

The Principle of Reciprocity

Journal of Magnetic Resonance, 2011
The circumstances surrounding the realisation that NMR signal reception could be quantified in a simple fundamental manner using Lorentz's Principle of Reciprocity are described. The poor signal-to-noise ratio of the first European superconducting magnet is identified as a major motivating factor, together with the author's need to understand phenomena
