Therefore, the aquifer is essentially a dual permeability, fully saturated system in which conduits occur within a network of ubiquitous extensive, horizontally- and vertically-interconnected fractures.
A total of 499 mL CT was injected at the top of the flow cell and allowed to redistribute in the variably saturated system.
During the first stage of the experiment, 16.3 ml of liquid Hg0 infiltrated and distributed into an initially partially water saturated system.
In the partially water saturated system, in contrast with PCE, elemental mercury also acted as a nonwetting fluid, therefore having to overcome an entry head to infiltrate.
However, when a chelating agent such as PO4 3− ion is added in an air saturated system, the biocidal activity of iron nanoparticle is reduced because Fe(III) forms an insoluble metal chelate with PO4 3− ion.
Beyond the optimum the ions saturated system causes the analyte to be water soluble leading to a decrease in the recovery bMaximum buffering action at optimum mass where the PXD molecules are preserved against degradation results in optimum recovery.

In contrast to water saturated systems, unsaturated porous media are less frequently but increasingly assessed (see for instance, [115]).
Furthermore, in the partially water saturated systems, experiments showed that elemental mercury displaced both air and water, depending on the initial water distribution within the pores.
Waste rock piles producing acid mine drainage (AMD) are partially saturated systems involving multiphase (gas and liquid) flow and coupled transfer processes.
Therefore, in this study the infiltration behaviour of elemental mercury in fully and partially water saturated systems was investigated using column experiments.
As the code can only model fully saturated systems, natural systems must be simplified to end-member situations, such as given by constant pressure boundary conditions as may be the case close to underground CO2 plumes, or the assumption of packages (batches) of water reacting along a reaction path with a homogenous sediment or rock body.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
