Positional FEM adopts as main variables the current nodal positions instead of displacements as classical finite elements do.
Slant angle, rear box angle, boat tail angle, and rear box length are considered as main variables of the rear end.
This is due to the small amount of research focused on these parameters [14], even though they have been considered as main variables for obtaining ultrafine nanofibers [15 18].
Based on the preliminary investigations, four parameters (number of hydrogen membranes, number of oxygen membranes, direct oxygen feed rate and steam-to-carbon feed ratio) are carefully chosen as main variables for the process optimization.
As mentioned, stage II of parametric study was performed on a set of columns considering two parameters, axial stress ratio and aspect ratio as main variables to investigate the ductility of UPTSCs.

To achieve the best surface conditions, the minimum amount of porosity and residual stresses in the melting zone, parameters such as current intensity, scanning velocity, distance from surface, electrode angles of TIG system and number of remelting passes were selected as main variables.
Spiders and velvet mites were ruled out as main variables of the PCA as they had a null contribution to the overall explained variance.
In addition, for all evaluated factors only MMP-8 came up with Cox's regression model when age, gender and stage were installed as main variables.
Given that the CopDiff database was constructed on the basis of existing DIFFs, any researcher with a hypothesis not directly involving leukocytes as main variables of interest should bear in mind the risk of inappropriately excluding potential relevant individuals if such cases have not been referred to DIFF sampling by their GPs.
