In order to experimentally confirm LoQ, six standard solutions with concentrations close to the LoQ were prepared and analysed.
The productivity can often be increased by operating the process at low dissolved oxygen concentrations close to the limitation level.
Further emissions reductions from carbon capture and sequestration (CCS) technology can reduce global atmospheric carbon concentrations close to preindustrial levels by the end of the present century.
All samples had DO concentrations close to, but less than, 10 mg l−1, taking into account changes in field water temperatures.
The samples taken at depth at each site had organic C and P concentrations close to the average values for each core (Fig. 2).
The high-volume sampler allowed measurement of pollen concentrations close to the source and even under turbulent wind conditions in the field.
From an atmospheric pollution perspective, the boundary layer height (BLH) is the main driver of the aerosol concentrations close to the ground.
In accordance with the predominant wind direction in Europe, the model predicts high concentrations close to the major sources as well as towards Central and Northeast regions.
At concentrations close to those of L-type calcium channel blocking ones, compound 12 did not affect mitochondrial functioning; also, no toxicity was obtained in vivo.
Terbuthylazine-desethyl was evident at W2 from 1 week after herbicide application onwards, at concentrations of <0.3 μg L−1, and was intermittently recorded at W3 from 1 month after herbicide application with concentrations close to, or below, detection limits.
This phenomenon was even more pronounced at 60 min post injection, where the isoflurane anesthetized mice still had brain concentrations close to 10%ID/g, whereas no discernible [18F]flumazenil binding remained in brain of the awake mice.
