Fig. 4. Relationship between the number of C. turbinata thread droplets contributing to thread stickiness, as measured with contact plates of four widths, and the mean stickiness per thread droplet. This example shows how we compensated for a decrease in the per droplet stickiness due to inadequate thread elongation, which resulted in five additional droplets contributing to a thread's stickiness. Multiplying these five droplets by the slope of the regression line and adding this product to the measured stickiness per droplet corrects for the effects of thread elongation, which was less than intended.
