1. With David Williams he has written two influential textbooks on diffusion processes . 2. As with all diffusion processes , this is highly dependent on the temperature. 3. Britain also produced the powdered nickel required by the gaseous diffusion process . 4. If the reaction term vanishes, then the equation represents a pure diffusion process . 5. The second term is the free particle propagator, corresponding to times a diffusion process . 6. Usually, convection occurs as a result of the diffusion process . 7. The gaseous diffusion process remained more encouraging, although it too had technical obstacles to overcome. 8. Over the next three years, Libby worked on the gaseous diffusion process for uranium enrichment. 9. Due to this'diffusion process social contagion and social conformity then set new fashion tastes '. 10. The eigenvectors and eigenvalues of the Diffusion Tensor give a complete representation of the diffusion process .
