radius of gyration

n
(General Physics) a length that represents the distance in a rotating system between the point about which it is rotating and the point to or from which a transfer of energy has the maximum effect. Symbol: k or r. In a system with a moment of inertia I and mass m, k2 = I/m

The molecular weight dependence of the z-average radius of gyration obtained by light scattering was determined by plotting [R.sub.g, z] as a function of [M.sub.z] in order to minimize polydispersity effects [ILLUSTRATION FOR FIGURE 4 OMITTED].
The radius of gyration ([R.sub.g]) was estimated based on the Guinier analysis; the result showed that the value of [R.sub.g] is in the range of 14.7-17.6 nm.
The radius of gyration derived thusly serves as a lower limit, since in actuality the aggregates are known to be less compact, with the typical fractal dimension of soot being ~1.8 [40].
They concluded that, to induce non-Einstein-like viscosity behavior, the polymer must be entangled, and the separation distance between nanoparticles should be comparable to the polymer radius of gyration. They also found that fullerenes resulted in a similar viscosity reduction at a mass fraction of 0.02 [13].
Where [R.sub.g] is the radius of gyration (with [R.sub.g.sup.2] = [na.sup.2]/6 for v = 0.5).
Figure 12 shows the center-mass points for each period as well as each calculated radius of gyration. We find the three center-mass values are within a reasonable range of each other, given the global scale.
Isolated countries such as New Zealand or Australia had an average radius of gyration of over 700 km.
Setting l = N[[lambda].sub.C] and minimizing equation (25) relative to R, we obtain for the radius of gyration [R.sub.g] the relation
Figure 6(b) presents the relationship between the average size of the islands (the average radius of gyration: [R.sub.avg]) and the average number of particles ([N.sub.avg]).
Radius of Gyration. We performed Rg in order to understand the levels of compaction of the native and mutant class PMP22.
According to the light scattering theory [25-27], weight average molecular weight (Mw) and root mean square radius of gyration (<[R.sub.g]>) of polymers were measured by static light scattering.
