The derived air concentration (DAC) ratio of the activation products decays to less than unity within 2 days, with only argon-41 remaining.
Thus, the above mentioned discrepancy between the estimated and advertised accelerometer bias values would then lead to an error level of about 5%and2.5%5% for GRACE and CHAMP, respectively, in terms of the mean non-gravitational acceleration and the derived air drag values (Eq. (2)).
In these latter analyses with IVGTT-derived AIR as gold standard, HOMA-B again revealed the weakest correlation and, thus, was confirmed to be less useful for the detection of impaired β-cell function.
We derived air pollution exposure measures using data from government air monitoring stations that provide information on spatial and temporal variations in criteria pollutants, and from a land use regression (LUR) model we developed for the Los Angeles Air Basin.
Finkelstein and colleagues [ 26], found that although markers of traffic derived air pollution did not predict PD risk, risk was increased among participants with higher Manganese (Mn) exposure (RR: 1.03; 95% CI: 1.00-1.07) for each 10 ng/m increase in Mn concentration) [ 26].
To understand the observed amplitudes of infrasound waves, it is useful to derive the air particle velocities from the observed f D fluctuations.
Subtle and vastly important chemical changes are constantly in progress, converting elements derived from air and water into forms suitable for the support of plant life, and in all these changes living organisms are active agents.
This paper describes an inverse or inferential modelling method for deriving cardinal air temperatures from seasonal growth measurements obtained from a simple field trial.
The BAER map, derived from air photos, also did not capture the distribution of scorched trees that were observed in the AVIRIS map.
In the Mount Washburn area of Yellowstone, a comparison of the AVIRIS map of forest cover types to a map derived from air photos resulted in an overall agreement of 74.1% (kappa statistic=0.62).
