For the determination by ratio derivative spectrophotometry, the first derivative of the ratio spectra (the spectra of benzophenone divided by the spectrum of 5.0 μg/mL phenytoin solution) was recorded.
This data was used for determination of ratio between the hospitalized cases and the total cases, termed as hospitalization ratio.
Spontaneously voided morning-urine was sampled in weeks 2, 7 and 12 or 13 for determination of ratios of adrenaline (A) and noradrenaline (NA) with creatinine (CR).
The steric factors, S (partition coefficients), of the solutes evaluated from the first moments of the column responses were used for the determination of ratios of solute and pore sizes λ.
Microarray data for transcriptome analysis were normalized using Loess, and for RNA stability determination expression ratios were median-centred.
Even in teleost species that exhibit genotypic sex determination, sex ratios can still be heavily skewed with hormone exposure before sexual maturation [ 9, 10].
Determination of ratios of nonsynonymous mutation rates and synonymous mutation rates (dN/dS) to normalize for variable evolutionary distances revealed that the exon sequences from the various CEACAMs are under different selective pressure.
Our results may be clinically relevant, since a simple determination of PaO2/FIO2 ratio may provide very important information for determining outcome, both in terms of mortality and length of stay, in the immediate postoperative care of cardiac surgery patients.
Observations made during occultations cannot provide direct information about atmospheric composition, but they can allow determination of the ratio of mean molecular weight to temperature.
Chiang et al. presented adaptive DL and UL channel split ratio determination in[13].
