The values of 'k' for the concentrations of 0.5 g [L.sup.-1], presented in the graph of Figure 3, were calculated using the logarithmic curve
equation, generated by the experimental wear data, for the concentrations of 1, 2, 3, 5 and 10 g [L.sup.-1].
where [r.sub.22] and [r.sub.c] are the curvature radii of the roller and the logarithmic curve
A logarithmic curve
provides a reasonably good fit to both sets of observed data, with most of the increase in home advantage occurring at crowd sizes of less than ten thousand.
As shown in Figure 6, the increase in compressive strength in the first curing days may be represented by a logarithmic curve
. The compressive strength increases fast during the first days but decreases gradually with time.
Referring to the adjusted R2 values of the logarithmic curves
for the individual confidence distributions, we took this value as a basis for analysing the range of effects at a step of 50m, with the best-fit matching the logarithmic curve
of 95 %.
