Because it is difficult to directly compare luciferase activity levels between two cell lines, we decided instead to observe differences in the trend of luciferase activity of different constructs in each cell line.
"Because we were measuring the fish in the fished areas and comparing them to the same species in the unfished areas – and we found substantial differences in the trend over the 10-year period – we can ascribe that to the impact of fishing," study co-author Trevor Ward, a marine scientist from UTS, said.
No significant differences in the trend of the mean are visible when changing the beam position.
At 2 years postoperatively, significant differences in the trend among HOS-ADL, HOS-Sports, and mHHS scores were evident, with normal BMI patients, followed by underweight patients, demonstrating greater scores than their overweight, obese, and morbidly obese counterparts.
Joinpoint regression identifies the points (years) in which there were statistically significant differences in the trend of a chosen outcome and quantifies the short-term increase or decrease between two successive points of change (Kim et al. 2000).
The results are shown in Fig. 12, and the comparison of pristine PSi (black curve) and grafted PSi (green curve) does not highlight any relevant differences in the trend of the curves enforcing the 4-NBD functionalization process.
To see whether there might still be a residual effect in the corrected data, a recent paper (Parker, Nature, 2004) looked at the differences in the trends if you looked separately at windy and not-so-windy conditions.
The results show that there appear large differences in the trends of gaseous temperature and mass fractions of chemical species in the mixture fraction space between the spray flame and the gaseous diffusion flame.
