Sentence examples for numerical concentration from inspiring English sources

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

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].

The highest microplastic concentrations measured in subtidal sediments, 2175 items/kg dw in the lagoon of Venice [22] and 3600 items/kg dw in the Rhine estuary [89], are lower than the LOEC of 10 g/kg sediment ww (1 % w/w [177]) derived in a water/sediment test with marine polychaetes, which corresponds to a numerical concentration of roughly 106 items/kg sediment dw (Additional file 1: Table S3).

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.

The Canadian study did not report numerical concentration data.

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

An effort was made to report, as far as possible, numerical concentrations of microplastics for studies on occurrence, uptake and effects.

The analysis of the process was performed by varying four significant independent variables, including four numerical factors (concentration of 4-NP, dofage of photo catalyst, initial pH and reaction time).

Numerical stress concentration factors at the hole of the autofrettaged pressure vessel subjected to internal pressure were approximately 3. Fatigue damages, including the mean stress effects, were evaluated using the local stresses and local strains determined from the elastic plastic finite element analysis.

The reconstructed concentrations were then plotted against the true numerical phantom concentrations for each data mix.
