It was ascertained that an increase in the microbial concentration hinders the gas-liquid oxygen transfer rate in the boifilter due to the coalescence of air bubbles, while the oxygen transfer rate is considerably higher than that in the activated sludge aeration tank at the same gas flow rate.
Finally, the results indicate that PPF crosslinking was facilitated at low DEF precursor concentrations, but hindered at higher precursor concentrations.
For hydrocyclones, the so far developed factor does not consider the effect of concentration of solid particles c in the feed stream, because particle interactions at high concentrations cause hindered settling and reduce hydrocyclone performance.
However, the maximum sediment concentration could reach more than 800 kg/m3 in several spots during a short period of time; there is a concern that the high suspended sediment concentration may hinder the settling of sediment grains (van Rijn, 2007).
This is of particular assistance where there is no prior knowledge of a patient's normal (baseline) creatinine concentration which hinders a diagnosis of AKI on admission.
For the carrier mobility, dopant materials as the scattering center, the carrier mobility will encounter more hindered concentration with increasing Li amount, which leads the decrease of mobility.
In particular, the equivalent area factor is modified at high particle concentration by applying different forms of hindered settling concentration functions and using data obtained from experiment or from existing empirical correlations.
Calculations well agree with experimental data and show that, even if cracks start at GO sheet edges due to stress concentrations, crack propagation is hindered by the nonlinear behaviour of the matrix.
However, the dearth of studies on indoor and personal concentrations of HAPs has hindered the development of accurate exposure models.
A limitation of the present study was the high percentage of blood samples with Mo concentrations < LOD, which hindered our ability to further investigate dose response relationships and metal metal interactions.
