For example, all Latin American airlines in the sample operate a FB page, but less than 70%% of airlines from the Commonwealth of Independent States do so.
Their results "showed that only approximately 60% of the nursing homes included in our sample operate close to the national standard for efficiency".
Therefore, as to research question Q1 stated at the beginning of this paper, we can conclude that the countries in our sample operate on the flat-of-the-curve.
While various grouping methods have been proposed, the consistency in parameter estimates in our study – regardless of exposure metric used – suggests that PCBs in our sample operate to decrease gestation via a similar underlying mechanism regardless of hypothesized differences in mechanism of action.
The arterial pressure was recorded, sampled, operated and processed in the chip system.
Standard tissue samples (operated and contralateral tibia, contralateral muscle, blood, heart, kidney, liver, lung, plasma, and urine) were excised, weighed, and measured for total radioactivity using a gamma counter (1480 Wizard 3", PerkinElmer/Wallac, Turku, Finland).
Time integrated indoor air concentrations of PCBs and PBDEs were obtained from a low volume air sampler operated over a 50 d period alongside the PUF disk samplers in the same office microenvironment.
It is also important to bear in mind that the patient study sampling operated inclusion and exclusion criteria, whereas the practice database study recorded visits by patients with all manner of complaints, of which back pain may have been only one.
This developed PM2.5 sampler operates at a flow rate of 15 LPM.
