Materials and Methods: Thirty students who had 18-26 years old, body fat between 15-25 percent and VO2max between 35-45 ml/kg/min, simple randomly selected through 200 physical education students and they were divided into...
A genetic analysis of time series, i.e., long stretches of repeated observations such as typically encountered in psychophysiological research, raises problems that are related to the proper handling of autocorrelat ion. Fo r instance, a standard univariate technique such as A N O V A of repeated measures is based on the assumption of compound symmetry of the autocorrela t ion function. This me...
This quasi-experimental study investigated the effect of bottom-up and top-down instructional approaches on English as a foreign language (EFL) vocabulary recall and retention. To this end, 44 high school students from two intact classes were assigned to bottom-up (n = 21) and top-down (n = 23) groups. The participants were exposed to 20 hours of explicit vocabulary instruction during 10 weeks ...
In this manuscript we present various robust statistical methods and show how to apply them in R using the WRS2 package. We elaborate on robust location measures and present robust t-test versions for independent and dependent samples. We focus on robust one-way and higher order ANOVA strategies including mixed designs (“betweenwithin subjects”). Finally, we elaborate on running interval smooth...
INTRODUCTION Presence of surface defects in endodontic instruments can lead to unwanted complications such as instrument fracture and incomplete preparation of the canal. The current study was conducted to evaluate the effect of autoclave cycles on surface characteristics of S-File by scanning electron microscopy (SEM). METHODS AND MATERIALS In this experimental study, 17 brand new S-Files (#...

As a model for Neuropsychiatric dysfunction in NeuroAIDS due to HIV-1 infection and drug abuse, we analyzed gene expression in human neurons treated with cocaine and HIV-1 proteins tat and envelope (env). One-way ANOVA showed statistically significant genes among the treatment groups (p < or = 0.0005). The identified genes were then subjected to a "stepwise" analysis using a repeated measures A...
abstract background: most of the patients admitted in the intensive care units (icus) require an endotracheal tube and mechanical ventilation. in order to clear and maintain patency of the airways, endotracheal suctioning is required. therefore, the least detrimental way of endotracheal tube suctioning which can diminish the complications should be selected. the present study aimed to compare t...
