These specimens comprise an Ice Age genetic museum, and the DNA contained within them provide a means to observe evolutionary processes within populations over geologically significant time scales.
The maximum duration of published force-field-based MD studies of hydrated patches of phospholipids, currently a hundred 722) or more nanoseconds, 723) is by a wide margin too short to cover many bilayer-related phenomena with significant time-scale and length-scale differences.
Due to this significant paper, time scale calculus has attracted researchers of differential geometry [3 6].
The latter could be particularly significant if the time scale τ of synaptic dynamics is larger than the window width Δt.
Measured density exhibits a constant value with depth, indicating that chemical weathering gradients are not significant for the time scale of interest.
According to Fig. 2, the absence of detectable 29N2 and 30N2 indicates that alternative pathways such as coupled nitrification denitrification, anammox, and OLAND are not significant on the time scale of these experiments.
PLG is known as a biodegradable polymer, but the degradation of the PLG scaffolds was not significant in the time scale we studied (7 days).
In the minutes required to attain and stabilize the protein at a specific temperature, desorption of the protein film did occur, though as all experiments were conducted in fresh, protein-free solutions, the desorption was not significant in the time scale of a single cyclic voltammogram, collected at 150 mV/s.
After averaging the absolute values of the note errors in each melody (to account for negative and positive errors canceling each other out), the three-way repeated-measures ANOVA [group x time x scale (50 c versus 100 c melodies)] performed on the absolute error measure in mel50 and mel100 tasks revealed only a significant time-by-scale interaction [F 1,17) = 6.85, p<0.05].
This is very different from the biodegradation of dissolved oil shown in Figure 2B1 where the amount of initial microbial concentration has a significant impact on the time scale of biodegradation.
