Others argued that improvements in African-American education and Northern migration were responsible.
Zn migration is responsible for the formation of the CuxZn(1−x Oy active phase.
The decrease in the Kohlrausch exponent for these thick films suggests that the grain coarsening through grain boundary migration is responsible for the stretched regime of grain-size relaxation.
Increased ASMCs proliferation and migration is responsible for this ASM thickness change and contributes to the remodeling of the smooth muscle within the airway wall [ 4].
Further genotyping studies should be done to confirm or disprove the serotype 64b nature of specimens A and B. In the expanding universe of B. burgdorferi, in addition to small mammals, transhemispheric bird migration is responsible for spirochete dissemination.
The historical traditions also state that these migrations were responsible, along with a series of natural disasters, for the collapse of a great empire ruled by a people called the Toltec from their capital of Tollan, or Tula.
Recent studies suggest that south-to-north gene flow largely influenced present-day patterns of genetic variation in Southeast Asian populations and that late Pleistocene and early Holocene migrations from Southeast Asia are responsible for a substantial proportion of ISEA ancestry.
They support the hypothesis that kink formation, inversion and migration are primarily responsible for the low temperature relaxation in these polymers.
Majerus (1998) wrote, in the conclusion to his analysis of the peppered moth story, that "My view of the rise and fall of the melanic peppered moth is that differential bird predation in more or less polluted regions, together with migration, are primarily responsible, almost to the exclusion of other factors".
Migration and global tourism are responsible for cases diagnosed in areas where the disease is not endemic (1 ).
