Continuous circulation of HBV strains in closed communities may lead to the unique HBV adaptation under selection pressures acting specifically on their populations.
Continuous circulation of these viruses in LPRSs increases the chances of their evolution into new genotypes.
Continuous circulation of influenza A(H5N1) virus among poultry in Egypt has created an epicenter in which the viruses evolve into newer subclades and continue to cause disease in humans.
Continuous circulation of EV71 in the community was evident, since EV71 has been repeatedly detected and isolated from HFMD outbreaks worldwide every year from 1998 to 2008 [ 7, 9- 11].
And because continuous circulation is needed to keep organs healthy, deaths that occur outside a hospital are almost never a source of usable organs.
A continuous circulation of gas can be produced by connecting the two containers with another tube whose diameter is large compared with the mean free path.
In the living world as a whole, carbon and nitrogen are in continuous circulation, driven by the energy of sunlight (see biosphere).
They are thus of crucial importance to primary productivity and to many aspects of the continuous circulation of water in the Earth's atmosphere (the hydrologic cycle)—i.e., evaporation, transpiration, condensation, precipitation, and runoff.
The reaction mixture was cooled by the continuous circulation of cold water in the outer jacket.
Nonetheless, the fundamental way to improve DO levels is to ensure continuous circulation of water flow.
Therefore, this paper presents a continuous circulation sub which can be installed and removed easily.
