Introduction: The purpose of this in vitro study was to introduce the fiber reinforced composite bridges and evaluate the most suitable site and position for placement of fibers in order to get maximum strength. Methods: The study included 20 second premolars and 20 second molars selected for fabricating twenty fiber reinforced composite bridges. Twenty specimens were selected for one fiber la...
objectives: the gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this is a precise and controlled treatment that is done in 54 steps in 3 speech situations consisting of monologue, reading, and conversation. this study aimed at examining the effects of gilcu treatment method on the reduction of speech dysfluency of school-aged childre...

conclusions according to the results of this study, the stress level induced due to needle-stick exposure and its complications is high and interventions for reduction are essential. results the mean and standard deviation of stress experienced by nurses before and after the intervention were 64.94 ± 15.67 and 43.91 ± 10.73, respectively. findings indicated that education decrease needle stick ...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
In this paper we propose an improvement of the Kolmogorov-Smirnov test for normality. In the current implementation of the Kolmogorov-Smirnov test, a sample is compared with a normal distribution where the sample mean and the sample variance are used as parameters of the distribution. We propose to select the mean and variance of the normal distribution that provide the closest fit to the data....
the aim of this research was to investigate the effect of 8 weeks of aerobic training and omega-3 fatty acid supplementation on plasma sicam-1 in elderly men. in this study, 36 male non-athletes (aged between 50 and 70) were selected through available method and randomly divided into 4 groups (9 subjects per group): aerobic training+omega-3 supplement, aerobic training+placebo, omega-3 suppleme...
having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
