Finally, high isotacticity is also required for obtaining qualitative β-form spherulites, demonstrated by increased β-crystal content after removal of weak crystalline fraction of the sample.
This vital point about the United States, past and present, also brings home in an especially poignant way the fact that there are still many developing countries that confront, today, the issue of giving their poorest and weakest even a fraction of an acre of the earth's surface to call their own.
Still, if all of these penalties reinforce one crucial idea — that reducing the number of human-started fires is an absolute imperative — they nonetheless remain generally far too weak, representing only a fraction of the damage such fires wreak every year.
Furthermore, kM of MAA was observed to be a very weak function of the fraction of organic material in the system and of the temperature.
In this micromechanical model, the volume fraction of weak interfaces treated as the interphase model is quantified and incorporated into the n-phase differential effective medium model.
To ensure that the observed result is not entirely due to the overwhelming fraction of weak ties, we re-produced this result by considering a network with the same number of connections, degree, and overall fraction of weak ties as originally, but with the transport modes reshuffled among people.
Selectivity for trans-DeHN increased with the fraction of weak acid sites on the zeolite (measured gravimetrically, using TPD of n-butylamine).
Table 6 Re-generated result of Figure 11 by considering a network with the same number of connections, degree, and overall fraction of weak ties as originally, but with the transport modes reshuffled among people.
Experiment was carried out for 10 trials to produce some evidence that ensures that the result observed in Figure 11 is not entirely due to the overwhelming fraction of weak ties.
