Based on the experimental fact that the effect of a cold surface extends only to a finite distance which bears a constant proportionality to the radius of freezing, an approximate method is developed for the location of the freezing front and the determination of the heat flux at the cold surface.
If, however, the part of the landslide that traveled on the mound was completely rigid, then it is more appropriate to use the position of the center of mass rather than the front in the determination of the velocity.
The proposed methodology is based on the possibility of the digital holography in carrying out the whole reconstruction of the recorded wave front and consequently, the determination of the phase and intensity distribution in any arbitrary plane located between the object and the recording plane.
Pathologists have drawn attention to the invasive tumor front (ITF) in the determination of the biologic aggressiveness of oral cancer.
The electric potential could be converted to yield the radial stress and strain distribution in front of the crack which afforded determination of the domain switching zone as well as the hardening coefficient.
It is thought that the interaction between the segmentation clock and these gradients at the level of the determination front defines the segment size.
The retinoic acid (RA) pathway is graded in the opposite direction relative to FGF signalling and counteracts the latter, thus influencing the position of the determination front.
The position of the determination front demarcates the region where the PSM cells are able to embark on their segmentation program and the temporal periodicity of oscillatory gene expression becomes converted to the spatial periodicity of the somites.
FGF inhibitors, acting as putative mediators, may periodically suppress FGF signaling in the middle to anterior PSM around the position of the determination front in order to generate a discrete pattern, by which the position of somite boundaries is determined.
This suggests that the position of the determination front is shifted posteriorly in the PSM by a reduction in Wnt signaling.
