Sentence examples for numerical concentrations from inspiring English sources

(d) Same as (c) but with numerical concentrations.

(b) Measured mass and numerical concentrations of GPGP ocean plastics.

For numerical concentrations, we simply divided the number of debris pieces 10 50 cm and >50 cm within each mosaic by the area covered.

Table 2 Mean observed mass and numerical concentrations within the 1.6 million km2 GPGP for different size and type of ocean plastics.

When only numerical concentration was reported22,48, we estimated mass concentration by using the average ocean plastic mass from net tows where both mass and numerical concentrations were reported (m = 3.53 mg, SE: 0.10 mg, n = 872).

For this reason, main focus is placed on studies reporting numerical concentrations per water volume, sediment weight or sediment volume.

Using our calibrated microplastics distribution, we computed the mass and numerical concentration for individual size classes from scaling modelled concentrations by the ratio between average modelled microplastics distribution inside the GPGP and averaged measured concentrations per size class of stations inside the patch.

A numerical concentration polarization model was developed to enable local description of permeate flux and solute rejection in crossflow reverse osmosis separations.

In order to correlate the size, numerical concentration, and size distribution of free volumes with the nanostructure of crosslinked polysiloxane (cured MQ resin), free volumes of polysiloxanes of different degree of crosslinkage polysiloxanes were observed by positron annihilation lifetime measurements in the temperature range from 30 K to room temperature.

They found that between 1972 1987 and 1999 2010 the median numerical concentration of microplastics had increased by a factor of approx. 140 (from 0.003 to 0.425 items/m3) and the median mass concentration by a factor of 1000 (from 0.003 to 3 mg/m3).

In addition, the LOEC of 10 g/kg sediment ww obtained in the 28-days test [177] corresponds to a numerical concentration of roughly 8 × 105 items/kg sediment ww (see Additional file 1: Table S3), i.e. a higher concentration than used in the 14-days test [39].
