Thirdly, our two-step approach, using the model estimates in secondary analyses, potentially increased type I error in the secondary models.
This study examined the optimum pyrolysis conditions of polyurethane for the yield of a solid product with a high iodine number using central composite design (CCD) on the secondary model in response surface methodology (RS M.
In contrast, pre-treatment in the secondary pneumonia model does represent a realistic scenario for short-term, prophylactic immunomodulatory therapy.
The boundaries of this apparent conversion tract correspond precisely to the beginning and end of helix 240 (domain I) in the secondary structure model for 16S rRNA in Escherichia coli [ 58].
Within each spacer group, the ITS2 sequences were relatively constant in length (variation < 10 nucleotides), except for group D where sequences were either short (285 287 nucleotides) or long (315 319 nucleotides), and the difference was due to an indel at the terminal end of helix III in the secondary structure model (see below; Additional file 4).
Previous comparative studies observed that the A nucleotides are usually unpaired in the secondary structure models of rRNA, while most of the C, G and U nucleotides are base-paired [6].
Cluster is a random effect, in a secondary model the interaction cluster*time is also included as a further random effect.
In a secondary model, we assessed the association between receipt of palliative chemotherapy and the intensity of end of life medical care without including characteristics that might have changed since the decision to start palliative chemotherapy was made (that is, performance status, quality of life, treatment preferences, and terminal illness acknowledgment), and the results did not change.
To describe the effect of the changes in temperature on the kinetic parameters obtained after fitting the primary model to the UV-H inactivation data of E. coli, Salmonella Typhimurium, S. aureus, and L. monocytogenes in chicken broth (shown in Table 1), the corresponding secondary models for each microorganism were developed.
The WinBUGS code for our primary model and the Excel spreadsheet for our secondary model are included in the Appendices.
