Domains alignments

In the transition from the demagnetized state (H = 0 Af = 0) to saturation (H = large M = ), small domains (aligned favorably with the field)... 

Layered Anisotropic carbon domains aligned in concentric layers parallel to the particle surface similar to an onionUke pattern... 

When an external electric field is applied, domains aligned favourably grow at the expense of others. As with ferromagnetics, the response to the field exhibits... 

An account has now appeared in which the domain-domain alignment determined using RDCs exhibits potential discrepancies with the alignment determined using NMR rotational diffusion measurements. In a study on polyubiquitin chains, Fushman and co-workers found small differences in the relative alignment of two ubiquitin units in Ub2 determined using RDCs and rotational diffusion measurements.124 The NMR study... 

When the there are equal numbers of domains aligned in opposing directions, their magnetic fields cancel externally so the material appears not to be magnetized.

In their ferroelectric state, the electro-optically useful PLZT compositions have an almost cubic structure, with the polar c axis being typically only about 1% longer than the a axes. Consequently the optical properties are almost isotropic and this, in part, is why high transparency can be achieved in the ceramic form. When an electric field is applied to the ceramic, domain alignment, or a field-enforced transition to the ferroelectric state, leads to the development of macroscopic polarization and so to uniaxial optical properties, i.e. the optic axis...

FIGURE 5 PKG forms in eukaryotic cells. The enzymes isolated from mammalian sources (type la and Ip and type II) and the Drosophila enzymes DGl and DG2 have their domains aligned and homology indicated. The positions of the autoinhibitory domains, ATP binding sites, and catalytic sites are shown. Reprinted with permission from the R. G.
