The initial concentration of the second stage unit and adsorbent weight have been designated as variables and these have been studied under two conditions of the equilibrium solid-phase concentration, qe, namely, when qe is a variable and when qe is a constant.
P value of log-rank test for all factors was less than 0.01 (except number of lymph node examined, P = 0.013) when 5-year cancer-specific survival was designated as dependent variable.
The processing operations included: drying, juice extraction and compaction with parameters affecting the process as independent variables while the responses (to the parameters), designated as dependent variables.
Therefore, the scores for these measures were designated as "endogenous variables" (outcomes).
Gender, age, and baseline care needs level were designated as control variables.
The PANSS and MADRS assess symptoms, and the BACS-SCT measures processing speed deficits which are assumed to be more direct or proximal manifestations of schizophrenia; therefore, the scores for these measures were designated as "exogenous variables" (predictors) in this study.
If it is of particular interest to maintain one of these as constant as possible whereas variations in other metabolite concentrations are less detrimental to biological function, then the former may be designated as the 'controlled variable' and the latter as 'manipulated variables' in the control engineering analysis.
In this work, a novel temperature control scheme is derived for an ideal heat-integrated distillation column (ideal HIDiC), in which a temperature difference between two stages is designated as the controlled variable to circumvent the side-effect of continuous pressure variations in the rectifying section.
Newly registered HIV-positive TB patients placed on ART were designated as the dependent variable for identifying potential associations.
A score of correct answers was calculated for each participant, and then designated as a score variable.
