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.
A simple color test could determine whether the collisional model is correct, says Paul Kalas of the University of California, Berkeley.

Contrary to previous expectations, the new model predicts that the collisional shift in a cesium fountain clock could be greatly reduced if the clock could be operated at a much lower temperature, in the range of 50 nK.

The closing of ocean basins through subduction means that the ultimate fate of these turbidite sequences is to be highly fragmented and deformed in subduction zone accretionary wedges and eventually to form part of collisional orogenic belts, and become welded into the crystalline metamorphic fabric of continental crust.
What is genomically interesting is that DNAs were mutated in this experiment into lower structures by collisional ejection of oxygen or carbon.
