The trick is to make the rules of public life clearer without making them rigid.
Both molecules contain particularly stable arrangements of cross-linking hydrogen bonds between the β-strands and a single disulfide bridge, making them rigid and well defined in solution.
Taxol binds to β-tubulin and stabilises microtubules by making them rigid and less dynamic [13].
And in his essay on Shakespeare, he attacks the rigid insistence on unity of time, place, and action in classical French theater by arguing that these ideals grew naturally out of the circumstances of both Greek theater and Greek life, but that it is absurd to make them into rigid rules in the very different circumstances of both modern theater and modern life ("Shakespeare," pp. 162 3).

Unfortunately, integrating security into these solutions is often perceived as making them more rigid [4].
In Fig. 7C, only the smaller vasculature compliance was modified by making them more rigid (β = 5) than our 'normal' value β = 2 trying to simulate experimental observation by a decrease of compliance naively expected in atherosclerosis.
There are numerous types of commonly used plastics with differing structures, properties, and chemical additives to make them stronger, more flexible, more rigid, more resilient to UV, or to prevent microbial growth or the spread of fire.
Leagues exist, but they're not as rigid as we make them out to be, Kazez said.
