However, Europe has also been subject to migrations and invasions within historical times, and these may have played an important role in shaping current patterns of diversity and could contribute to confusion over more ancient population movement.
On the 21st day after collection of eggs, the adult flies were sexed, censused, subjected to migration (see below), and allowed to lay eggs for 24 hours in vials containing ∼1 ml banana-jaggery medium.
Two different grades of carbon black were incorporated in these polymer types and the composites were subjected to migration experiments.
To determine the basis of these observations, human breast and non-small-cell lung cancer cells were subjected to migration and invasion assays in the presence of bexarotene.
To determine whether LEDGF overexpression in these cells was functionally involved in enhancing tumorigenicity, cells overexpressing LEDGF were subjected to migration and invasion assays.
Two types of carbon black were incorporated in low-density polyethylene (LDPE) and polystyrene (PS) at 2.5% and 5.0% loading (w/w), and then subjected to migration studies.
NO-treated (14 days) and parental H23 cells were subjected to migration assay as described in Materials and Methods Section. Figure 2 shows that lung cancer cells exposed to NO for 14 days exhibited significantly enhanced migration activity.
Leading leave campaigner Michael Gove, the justice secretary, warned that Britain would be subject to a migration "free-for-all" by the addition of countries including Albania and Turkey to the EU.
The channel system is characterized by complex channels of different periods, while the formation of complex channels is subject to the migration patterns of single channels.
There is a growing concern about this large river system because its channels are subject to frequent migration, threatening engineering structures and resulting in various environmental and social consequences which may be compounded by climatic variability, land use change, and agricultural intensification as the basin experiences rapid population growth.
