The attenuation curve of CA1 (gadolinium-based CA) within a region of interest (ROI) in the abdominal aorta was used as a test bolus to determine the individual patient-specific timing of the blood circulation and the maximum of arterial contrast enhancement.
The first and second waves were defined from the identified reports, based on the timing of the global circulation of the virus: approximately July 1968 to August 1969 for the first wave and September 1969 to September 1970 for the second.
However, there are notable geographic variations in the timing of RSV circulation across the United States (27).
An influenza year was defined as week 26 of a given year to week 25 of the next year because the timing of influenza circulation during a given winter usually spans two calendar years (ie, extends from October of a given year to March of the next year).
The winter peak in Srinagar is similar to the timing of influenza circulation observed for most countries in Europe and United States in the Northern Hemisphere (4, 5 ).
The model automatically downloads data from any weather station in Arizona, allows specification of various cover and liner conditions, specifies the timing of circulation, and has a dynamic simulation mode.
We did not use the site-specific or age group–specific virologic data to ascertain whether true differences existed in the timing of influenza virus circulation between these specific groups.
The use of either the Northern or Southern Hemisphere vaccine depends on the pattern and timing of seasonal influenza circulation.
This is the first molecular epidemiology-based study in Italy which aimed to investigate the characteristics and timing of circulation of CRF02_AG in HIV-1 infected people, in particular in MSM.
This is likely due to the RSV season which is defined by the timing of the onset and offset of increased RSV circulation in a community.
Using the proposed solution procedure, the optimum number of stages, the number of membrane modules per stage, the feed and circulation pumps sizing, the work pressure profile and the timing of the operating and cleaning tasks, are determined.
