On the other hand, porous non resorbable scaffolds have the advantage of maintaining ridge shape and dimensions during healing time.
For uniaxial SD magnetite particles, FORC diagrams show a narrow ridge shape centered along the H c axis (Pike et al. 1999).
Because no feature of magnetosomes (a narrow ridge shape) is found in the FORC diagrams, no clear evidence reveals the presence of magnetosomes in the core.
This shape has never been observed in FORC diagrams of other magnetic particles, which may support that the narrow ridge shape is a unique feature of SD magnetite (Egli et al. 2010).
As a result, instead of showing a narrow ridge shape, all the FORC diagrams present the feature with a stronger signal of a teardrop shape and a weaker signal of spread along the H u axis in the study (Fig. 3c f).
It is clear that the general ridge shape has been recovered with some error.
We further evaluated our system performance by imaging another phantom sample having a ridge shaped surface topology, created by placing layered tape on top of a clay.
Along one edge of the ootheca is a seam that bears a keel, or ridge; the shape of the ridge varies in species that carry the ootheca externally.
The cross section extracted along the ridge line shape parallel to the F2 axis was fitted using the DMFIT program.
In particular, double ridge transverse shape may be an instrumental aspect in identifying potential inverted fluvial landforms.
