Mr. Obama's self-image, as he makes clear in his memoir, "Dreams From My Father," rested on just the opposite principle: the fluidity of identity, the American possibility of free self-invention.
A major adaptation among the winter tolerant species is the ability to maintain the fluidity of membranes by reducing the ratio of free sterol to total phospholipids.
I'd expect someone of his imaginative fluidity to be free of such retrograde stereotypes.
It has also been documented that supported bilayers preserve many properties of free membranes such as lateral fluidity [46].
They stabilize membranes by decreasing the membrane fluidity (in a concentration-dependent manner) and hinder the diffusion of free radicals and restrict per oxidative reaction [ 136, 137].
Walt Whitman's poems inspired him to write the symphony, and Whitman's use of free verse became appreciated at a time where fluidity of structure was becoming more attractive than traditional, metrical settings of text.
For instance, PrPSc accumulation promotes an increase in the level of free cholesterol, and is associated with a reduction in membrane fluidity, which may amplify the duration and/or strength of signaling.
Cellular membranes, which contain abundant phospholipids, such as phosphatidylcholine (lecithin), are major targets of free radicals which induce lipid peroxidation and thereby cause malfunctioning of membranes by altering membrane fluidity and membrane bound enzyme and receptor functions [ 43].
The free-floating camera and dramatic fluidity of the silents seem to screech to a halt with Borzage's first all-talking picture, the 1929 Will Rogers vehicle "They Had to See Paris".
The fluidity of the data is in itself an indication that "free movement of people" within the union was never meant to be seen as migration – rather as a flexible arrangement beneficial to everyone, by expanding employment horizons and opportunity.
