Sentence examples for maximum concentrations observed from inspiring English sources
Concentrations of DSi in marsh water are two- to fivefold higher in comparison to maximum concentrations observed in the upper reaches of estuaries: the average riverine DSi concentration is 100 μM (Conley 1997), but higher concentrations (up to 250 μM) have been observed in the freshwater tidal reaches of the Scheldt estuary (Belgium) (Carbonnel et al. 2009).
The May 2010 and June-1 maximum concentrations observed in air are similar to the LA site.
While the particulate matter concentrations averaged over incident durations are lower than the concentrations used in many human clinical studies, the maximum concentrations observed for 1.5 and 2.5 seconds (i.e. the length of a breath) were 2 to 3 times higher than the concentrations used in many human clinical studies.
However, the threshold cell concentrations (i.e., 1×104 and 4×104 cells ml−1) above which the ingestion rate of diatoms became constant was far above the maximum concentration observed in the field.
The maximum concentration observed in groundwater at the West Valley Demonstration Project in 2007 was 5.6 pCi/L (West Valley Demonstration Project, 2007).
Despite the high maximum concentration observed in yolks in the present study, the mean (1.39 ng g−1 lipid) and median (0.052 ng g−1 lipid) ΣHBCD concentrations were similar to the levels reported by others.
For BDE 209, the concentrations were notably higher in individuals who had recently completed a cross-country (USA) flight (median: 84 v. 26 ng/sample (total of palm and back of hand)), and the maximum concentration observed was nearly two-fold higher (470 v. 270 ng/sample (total of palm and back of hand)).
For a single intravenous fidaxomicin dose in rats, the 50% lethal dose was approximately 200 mg/kg and the no observed adverse effect level (NOAEL) was determined to be 62.5 mg/kg; at this NOAEL dose, the peak plasma level of fidaxomicin was 3000 10 200 ng/mL, which is at least 300-fold higher than the maximum concentration observed in humans.
The arc maximum surface concentrations observed within the array were well explained by a dispersion model based on that of Van Ulden [1978. Atmospheric Environment 12, 2125 2129] and modified by Venkatram [2004.
However, the maximum ethanol concentrations observed by the ydr307wΔ/ydr307wΔ and yhl042wΔ/yhl042wΔ strains were 7% lower (p-value = 0.003) and 8% higher (p-value = 0.002) than that of the wild type strain, respectively.
These results agree with those presented by Nakatani et al. (1984), where increased amounts of valine supplementation resulted in increased valine uptake and decreased maximum valine concentrations observed during fermentation.
