As such, the CIs of the simulated concentrations should be considered with caution.
As measured in hair, the concentrations of all the metals considered, with the exception of arsenic, in cases were significantly higher than in controls.
Concentration and temperature regulation is considered with the simultaneous estimation of the frequency (or pre-exponential) factors of the Arrhenius equation.
Here, the main variables e.g. pH, sorbent dosage (m), and initial concentration of phosphate (CP) were considered with an assumption that they were likely to be influential on both removal efficiency (R %) and capacity uptake (q).
Two articles [ 6, 13] report that probe set 546_at should be considered with the same concentration as 36202_at since both of them were designed against the target Unigene ID Hs. 75209.
Two dust layer concentrations were considered: loose with an initial volume fraction of 1%, and dense with an initial volume fraction of 47%.
The partial differential equations of conservation of mass, linear momentum, angular momentum, energy and concentration are considered along with suitable boundary conditions in formulating the model for the physical problem and analyzing it theoretically.
θ can for instance be assumed to take the logistic form for simplicity; i.e. θ = 1 - (P + M + D), where each concentration is considered to be scaled with respect to the capacity of the system.
It is observed that though quantity adsorbed rose with the concentrations, however, considering in percentage removal term, with the rise in the concentration, the percentage uptake by the samples steadily diminished.
However, a comparison with WHO (2004) and USEPA (1999) threshold values of 20 and 16 µg g−1, respectively, indicates that a system with this concentration is considered as a polluted system.
