On the basis of linear approximation of the concentration gradient, the method of probability calculation is adopted to model the transformed fraction.
For the finite dimensional approximation of the concentration and the chemical potential piecewise linear and globally continuous finite elements are used, and for the numerical approximation of the fluid velocity Taylor Hood finite elements are employed.
The hBD-2 production) in a reconstructed skin model stimulated with proinflammatory cytokines was used estimate the concentration in the epidermal compartment in vitro, as an approximation of the concentration in psoriatic epidermis.
The availability of absolute measures of the ligand in tissue and plasma, the latter being a very good approximation of the concentration in the capillaries, allows the calculation of functional measures such as blood flow, enzymatic rates and protein densities via a kinetic model.
The amount of CO in 'end-expired air' is a good approximation for the concentration of CO in the blood and exhaled CO levels will be higher in smokers than in non-smokers.
A previous study has provided evidence that ethanol rapidly equilibrates across the worm cuticle and therefore this external concentration is likely to be a close approximation of the tissue concentration [18].
Additionally, calculating the rms value for both the free and ligand-bound receptors gives a reasonable approximation of the average concentration of receptors.
At this point, parasitaemia has almost invariably cleared, and a good approximation of the venous concentration is (capillary concentration 0.9.
Since there was little evidence of a systematic trend in the number of outliers at either Hb extreme, ABG analysis appears to provide a consistent approximation of the Hb concentration for most Hb values seen within the ICU setting.
In mild extraction, a variety of "soft" solvents (e.g., n-butanol, methanol, ethyl acetate) are used to estimate the readily extractable fraction as an approximation of the bioavailable concentration.
