Model A
Plots of ln(IPR) versus T representing Model Aare presented in Figure 1 . The straight lines drawn through the data verify the linear correlation between IPR and T for the five FAME studied in the present work. Results from least squares regression analysis of the data are summarized in Table 2 . These results yielded intercept and slope coefficients (A0 and A1) that were significant (p -value << 0.05). The A0coefficients for CaME, PME and SME were generally in a narrow range, from 28.1 to 31. The same trend was observed for the A1coefficients (−0.078 to −0.068) of these three FAME. In contrast, the A0 and A1 coefficients were significantly higher in magnitude for MeC18:1 (39 and −0.098) and lower in magnitude for MeC18:2 (22 and −0.059).
