Do we imagine that these texts reflect a religion continually concerned with protecting its rather rigid boundaries?
Hierarchies are rigid when it comes to the approval of the drafts and proposals prepared by a civil servant (fonctionnaire).
Each fills the tonal space that the other leaves void; each, as the rigid logic of head and body demands, personifies what the other lacks.
The simplest example of this mechanism occurs in a film on a rigid inclined plane bounded above by a thin elastic plate.
Its rigid anti-vibration structure enables several technologies to be incorporated: laser, water jet, machining spindles or non-destructive controls.
Multi-branched loops can play a key role in tertiary structure because they can act as flexible hinges between otherwise fairly rigid helical domains.
If high- or lowresolution models of all domains exist it may be possible to reconstruct the complete structure by rigid-body refinement as explained below.
The lineage as a genealogical map appears to be too rigid and static-based on blood and marriage.
