By employing the theoretical method based on tight-binding, we study electronic band structure of single-wall carbon nanotube (CNT) superlattices, which the system is the made of the junction between the zigzag and armchair carbon nanotubes. Exactly at the place of connection, it is appeared the pentagon–heptagon pairs as topological defect in carbon hexagonal network. The calculations are base...

conclusions the results showed a significant effect of electronic software and training booklet in raising awareness about newborn care and self-confidence. therefore, these methods are advisable to mothers. results after controlling the baseline values, the mean score of self-confidence in the training booklet group (adjusted mean difference = 5.6; 95% confidence interval = 1.2 to 10.0; p = 0....

introduction: the aim of this study was to evaluate the accuracy of two electronic apex locators (smarpex and novapex) in detecting apical perforation. materials and methods: after access cavity preparations, the working length was determined by the first examiner before and after perforation with a stereomicroscope by introducing a k-file size 10 into the canal and size 25 k-file up to the per...
