Given the evidence, it is more reasonable to postulate that the Second Solar Spectrum results from interface polarization and associated condensation reactions, rather than calling for anisotropic radiation, Hanle depolarization, and collisional depolarization.
It was observed that the quenching constant was lower in TSE melt flow than in solution due to the restricted collisional diffusion in melt flow.
Though the Alps have been studied by generations of Earth scientists as the prototypic collisional origin, recent findings, technologies, and concepts have radically altered the understanding of their past.
1), the SYNAPT G2 comprehensively detects components, reveals new or subtle features in the data, and provides more efficient data processing workflows such as the measurement of a compound's collisional cross section (shape).
Continued-fraction expansions for the effective thermal conductivity are established, leading to the expected limiting behaviours in collisional and ballistic regimes, and providing an interpolation in the intermediate regimes.
