As a major travel hub with a high volume of travelers from both hemispheres, Singapore could be a sentinel for detecting changes in the circulating virus strain and contribute toward an understanding of influenza virus circulation pathways.
The higher the number, the higher the likelihood of connections of a specific site with others (via physical circulation pathways).
Occasionally, these circulation pathways were interrupted or redirected locally by smaller scale eddies and filaments (Fig. 1b,d and f).
Such re-circulation systems normally have longer airflow circulation pathways, which inherently induced higher airflow resistance, resulting in higher fan power demand per unit of airflow rate delivered.
The building's design is dominated by structural tubes that support the floor plates and provide circulation, pathways that the Pritzker jury said "permitted new interior spatial qualities".
Because slumping fuel and salt from seawater that had been used as a coolant is probably blocking circulation pathways, the water flow in No. 1 "is severely restricted and likely blocked".
Changes in surface marker expression reflect changes in T-cell function, circulation pathways, and co-stimulation requirements, for example.
MRI images revealed no evidence of obstruction or occlusion of the cerebral aqueducts or other putative CSF circulation pathways.
However, clinical hydrocephalus routinely manifests without any detectable blockage of CSF circulation pathways [ 20- 24], and several reports have cast doubt on the role of arachnoid projections in this context [ 25- 27].
Large-scale molecular epidemiologic studies of influenza viruses, sampled from locations in different hemispheres, that investigate the circulation pathways could assist in the understanding of the reasons for the seasonality of the disease (44 ).
