Jackson's Western successors also altered the facts on the ground, settled land illegally as well as legally, and did not always have much regard for pre-existing local populations.
With aging populations, pre-existing immunity in particular could be of crucial importance for the cost effectiveness of options to mitigate a future influenza pandemic.
Indeed, it has been regularly observed that the incidence of adverse events is lower in populations with pre-existing immunity rather than higher.
Whether the pre-existing population in Scandinavia influenced it, or if it had already branched off when it arrived, is hard to say for certain at this distance.
For experimental runs for which there is a pre-existing population of particles in the chamber at the start of a run due to incomplete cleaning of the chamber, losses to this coagulation sink are accounted for by inserting the initial size distribution into the size bins of the model.
Fate mapping studies of the mouse embryo reveal that progenitors of the definitive or gut endoderm are recruited from the epiblast during gastrulation and they are incorporated into a pre-existing population of visceral endoderm which may also contribute to the tissues of the embryonic gut.
In each time step the population distribution method allocates the net regional population growth in a region, as projected by Eurostat, as well as 10%% of the pre-existing population in order to take internal movements into account.
"Each pet that is coming to Chicago was a part of the shelter's pre-existing population of homeless pets.
When, however, there is a small, pre-existing population of natural Treg cells (Treg(0) = 5), the same antigenic signal gives rise to tolerance.
Whole blood genomic DNA from Caucasian individuals living in the UK recruited to two pre-existing population cohorts (coordinated by the same research centre) was used for the experimental analyses.
To determine whether ICOS might regulate the development or survival of memory CD4 T cells, we investigated the pre-existing population of memory phenotype CD4 T cells in untreated ICOS−/− and ICOSL−/− mice compared to wild-type mice.
