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].
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).
For example, concentrations of p,p´-DDE in the CARDIA study was higher than in those of the current study and the Michigan study.
For example, concentrations of PAHs and particulate matter with aerodynamic diameter ≤ 2.5 μm (PM2.5) were highest during the winter (December February) and lowest during the summer (June August).
However, this is not universal; for example, concentrations of PCBs in Great Lakes fish have continued to oscillate (Bhavsar et al. 2007).
For example, concentrations of IL-8 were significantly higher in the WTC group than in the unexposed comparison group (765 vs. 342 pg/mL; p = 0.00003), as were concentrations of IL-1α, RANTES, and EGF.
For example, concentrations of Cd in the grain of many durum wheats grown on the North American prairies [ 4, 5] often exceed the maximum level for Cd in wheat grain (0.2 mg kg-1) established by Codex Alimentarius [ 6].
For example, concentrations of heavy metals (e.g., chrome, mercury, lead, cadmium) introduced primarily from anthropogenic activities in the Rhine River basin are higher during drought years (Zwolsman and van Bokhoven 2007).
The models are given by ordinary differential equations of the form: (24) Here, x i is the vector with the different states (for example, concentrations of different proteins) of the model i, i = 1, 2, f i and g i are functions that represent the different models, and u is the input, which can be externally controlled; for example, ligand concentrations.
