Sentence examples for concentrations collected over from inspiring English sources

However, the differences in observed relationships between specific social behaviours and glucocorticoids may be partly explained by sampling frequency, as studies often use average fGCM concentrations collected over a period of weeks or months, rather than fGCM concentrations that are temporally-matched with behavioural data.

The ability to analyse root secretion DMA concentrations collected over narrower time periods allowed for further characterisation of rice DMA secretions during this 'morning' period leading to the identification of 11 00 13:00 (3–5 h after the onset of light) as the peak time of DMA secretion from Fe-deficient rice roots (Fig. 3).

The experimental plasma concentration was collected over a time course of 0 to 600 minutes, with the first data points at 1, 2, 4... minutes and the last two samples at 300 and 600 minutes.

PCBT concentration in urine collected over 24 hr showed a very strong association with HCB concentration in serum; the association was stronger in males than in females.

Carryover effects were generally ignored, which may have been reasonable given that the impact of clearance mode on solute removal should manifest relatively quickly [ 8], and subsequent clearance and concentration measurements were collected over a period of 12 to 24 hours after crossover in most trials.

This database is quite comprehensive and includes soil TEQ concentrations from three counties collected over various sampling efforts between 1995 and 2003 by the MDEQ, EPA, Dow, and U.S. Army Corps of Engineers USACEE).

Atmospheric tracer concentrations (such as tritium) collected over large areas in heterogeneous aquifers and (or) in transient flow systems exhibit variations due to spatial and temporal changes in tracer inputs, in tracer transport in unsaturated and saturated zones, and in pumping stresses at sampling points.

We examined depuration rates of 12 PBDE congeners and 80 PCB congeners by measuring concentrations in serial samples collected over extended periods from two groups (n = 9 for each)—short-term (ST) and long-term (LT each composed of volunteers from a cross- sectional study of California primiparae (CS CA) (n = 82) (Table 1).

PATIENTS: A total of 29 full-term neonates diagnosed with HIE treated with hypothermia who received gentamicin and underwent therapeutic drug monitoring MEASUREMENT AND MAIN RESULTS: Patient demographics and gentamicin concentration data were retrospectively collected over a 2-year period.

Future studies should measure paraben concentrations in multiple urine samples collected over the exposure window of interest to reduce exposure measurement error.

The aims of the present study were to identify predictors of exposure to selected phenols and to determine the reproducibility of phenol concentrations across serial urine samples collected over several years among urban Chinese adults.
