Further, as is well established, CO2 has a much longer lifetime in the environment than does CH4, and will have climate impacts over a much longer time scale.
For building materials like concrete these measurements are performed on a much longer time scale than in flash lamp experiments.
Correspondingly, their solid phase low concentration valleys migrate down gradient slowly over a much longer time scale, long after the release stops on day 25.
In contrast, the relaxation in other nuclear coordinates was on a much longer time scale (2 to 10 picoseconds) and depended critically on cluster size.
From the experimental analysis it was quite evident that the spectral instability, which starts during the nucleation and growth stage in thin films, continues to persist at a much longer time scale following aging processes.
These studies demonstrate that the kinetics of formation of the incommensurate CuCl adlayer from the commensurate (1×1) Cu layer takes place in a much longer time scale than the current response.
From the viewpoint of degradation-induced morphology changes, PLA/CL behaved like PLA/GA copolymers but on a much longer time scale, PGA segments in PLA/GA copolymer playing the same role as the PLA ones in PLA/CL copolymers, i.e. being the more sensitive to hydrolysis.
In contrast, methods based on the differing proportions of non-synonymous and synonymous mutations is considered to be best at detecting selection that acted over a much longer time scale [16].
