This way, we circumvent non-geometrical influences and identify other effects deteriorating membrane performance, for example concentration polarization.
Even though other phenomena may be also involved (for example, concentration polarization), surface barriers may have a paramount importance in limiting the diffusivity of guest molecules and thus the permeability of membranes with nanometric thickness: equation (4) predicts a linear increase of diffusivity, and thus membrane permeability, with α.
For example, concentration guidelines for aluminum, cadmium, copper, lead, mercury, selenium, silver, and zinc are lower for aquaculture than for the other water reuse purposes.
Moreover, it could be also useful to compare the thermal response of different kinds of nanoparticles under different working conditions as, for example, concentration, optical density, dispersion media, or sample holder.
In the previous study, for example, concentration of glucose (200 g/L) was used and relative high concentration of 2,3-butanediol (95.5 g/L) was achieved (Ji et al. 2009).
Different pathways can lead to different preferred conformational states; however, pathways are strongly dependent on conditions, for example, concentration, sequence effects, pH, and temperature.
For example, concentrations in landfilled waste are lowest in South-eastern Europe due to dilution by the high amount of landfilled waste in the region.
For example, concentrations of many metals in solution are pH-dependent (Brookins 1988).
For example, concentrations of 0.5 to 1.0 mM Fe2+ are optimum for carbon-PTFE GDE cathodes because of their lower ability for Fe2+ regeneration [8, 35].
For example, concentrations were heptachlor (0.34 ng/g), aldrin (0.25 ng/g), DDE (0.18 ng/g) and heptachlor epoxide (0.12 ng/g).
Current pharmacological data demonstrate that mechanosensitive ion channels in DRG neurons and hair cells are different (for example, concentrations of gentamicin and amiloride that inhibit hair cell channels are inactive in the DRG).
