Basic science: Experiment research:e0232 The change of ventricular INa at different time of simulated ischaemia and the effect of atorvastatinObjective To observe time dependent effects of simulated ischaemia on transient sodium currents (INa) of rat left ventricular myocytes, and the effects of ...
What is an experiment in which all factors are identical except the one being tested? What is the difference between correlational and experimental research? What is an example of a dependent variable in science? What are the variables in a correlational hypothesis? W...
The central values of all dependent variables were calculated per trial. With regard to H3 (i.e., the effect of taking pauses on cognitive load during the pauses), in the PA we only used pupillometry data as the dependent variable, as this measure continually recorded pupil dilation during ...
Fourth, although we controlled the variables in our study as much as possible, such as paired samples students, the same teacher in each group, strictly following the study program to ensure consistency and relevance of the teaching content, and the lesson design that only varies in the developm...
effects of variety, plant age, nitrogen level and their interactions in the greenhouse experiment were examined using general linear models (GLM) with xylem-feeding, survival, planthopper biomass, biomass density, plant biomass change (per mg of planthopper), and eggs laid as dependent variables. ...
The total duration of the experiment was around 2.5 h. Data analysis A repeated-measures analysis of variance (ANOVA) was used to analyze the outcomes under study during the various auditory conditions as a within subjects’ factor. In this study, the dependent variables are sustained attention,...
Note that the variables; Hjm and Gjm are dependent on the input variable X, from the previously described data Dm. Further explanation of the colsample by tree level (Scol), subsample (Ssub), sparse-aware, and shrinkage information were discussed in paper by Chen and Guestrin [16]. In ...
Environmental outcomes are often affected by the stochastic nature of the environment and ecosystem, as well as the effectiveness of governmental policy in
