Sentence examples for mean pm concentration from inspiring English sources

Based on the daily semivariograms, we performed ordinary kriging to estimate the daily mean PM concentration and its SE at each of the 94,135 geocoded addresses.

In this study, we empirically tested whether the non-constant mean assumption for universal kriging was needed; we performed five regional ordinary krigings so that different parts of the country would assume a different mean PM concentration.

In the present study, the mean PM concentration (105.1 μg/m) was very close to the mean concentration of the third quartile in the fine CAP study (107.4 μg/m) and resulted in an identical percentage of PMNs in the BAL fluid, suggesting that coarse and fine PM may be equally potent in inducing pulmonary inflammation.

The capacity of PM to deplete GSH was best correlated with Al (0.55) and Cu (0.49 annual mean PM concentrations) (Table 3).

In Table 2 we present the mean PM concentrations for each averaging period for the overall sample and by trial arm and VTE status.

During the unfiltered DE exposure the mean PM concentrations within the chamber was 350 μg/m, with NO and NO2 concentrations of 2.49 and 0.68 ppm, respectively (Table  1).

We used data on the ambient concentrations of PM recorded at all U.S. EPA Air Quality System monitors operating in the contiguous United States and national-scale, log-normal ordinary kriging to spatially interpolate daily mean PM concentrations at each geocoded participant address during the study period (Liao et al. 2006; Whitsel et al. 2006).

We used age-stratified Cox proportional hazard models to examine the association between time to incident, centrally adjudicated VTE, and daily mean PM concentrations spatially interpolated at geocoded addresses of the participants and averaged over 1, 7, 30, and 365 days.

Some studies have found that PM10 and PM2.5 both appear to affect lung function in asthmatics (U.S. EPA 2004); however, many of the studies experienced higher mean PM concentrations (in the range of 50 μg/m) than were experienced by subjects in this study.

The mean coarse PM concentration (105.1 μg/m) measured at the inlet to the exposure chamber in this study is not unrealistically high and can be found in many areas throughout the world, including locations in the U.S. Southwest.

where W is the ambient NO concentration, ids is the PM reading for individual i on day d during session s, is is the mean PM reading for a subject during a session, i is the mean PM reading for a subject during all of their sessions, med i is an indicator variable for medication use (constant for each subject), and RH is relative humidity.
