Thus, benzoylureas (36) are attractive mimetics that allow facile and consecutive elongation of the scaffold to yield water-soluble structures with highly asymmetric substitution (if desired).[ 305] The aromatic rings of the terphenyls are replaced by a six-membered hydrogen-bond-assisted ring that provides some degree of rigidity and ensures the staggered disposition of the substituents.
We differentiate the measure into a deterministic metric and a statistical metric, and provide some general results on redundant rigidity.
In the middle segment of the femur, the OSF provides rigidity of fixation which exceeds the rigidity of the Ilizarov in the frontal, sagittal, transverse and longitudinal planes by 19.3, 1.07, 1.8 and 2.3 times, respectively.
Erection in such species results primarily from relaxation of the retractor muscle, and vascular engorgement provides only rigidity.
Steel framing is based on the same principles but is much simplified by the far greater strength of the material, which provides more rigidity with fewer members.
In high-voltage transformers, for example, solid insulation provides mechanical rigidity, while oil or other liquid substances contribute to increased insulation strength and serve to remove heat from the equipment.
Cellulose is the major element of plant cell walls which provides them rigidity (Beguin and Albert 1994).
Weighing only 2.3 ounces (.065 kilograms) FreeOneHand's lightweight elastomer construction provides enough rigidity to hold a 1.6 pound iPad, while keeping a rubber-like softness for comfort during use.
Slight inter-MWCNT entanglement along their axes, inherent to the growth process, provides sufficient rigidity for handling and manipulation.
The cyclic nature due to a disulfide bridge between Cys1 and Cys6 of vasopressin provides structural rigidity to the peptide hormone.
