the linguistic is studying the language different levels, the language is main topic  that the linguistic sisstu dying it. the linguistics has several branches,the stylistics is one of its branches that survey literary works. and stylistic phenomenon is one of the important phenomen as at linguistic studies and it study poetic language because it’s different from the common language. since the ...

Using differential quadrature method (DQM), this study investigated pull-in instability of beam-type nano-switches under the effects of small-scale and intermolecular forces including the van der Waals (vdW) and the Casimir forces. In these nano-switches, electrostatic forces served as the driving force, and von-Karman type nonlinear strain was used to examine nonlinear geometric effects. To de...

introduction: gastric drainage disorder is one of the complications of gastric pull-up and esophagectomy after surgery which might lead to esophageal cancer and benign strictures. the aim of this study was to determine the role of pyloromyotomy on gastric drainage. materials and methods: in this prospective randomized controlled clinical trial study, we studied 51 patients in two matched groups...

introduction: to evaluate the effects of using sodium hypochlorite irrigant on pull-out bond strength of self-etch and self-adhesive resin cements to dentin. methods: sixty intact premolars were decoronated and the root canals were prepared by step-back technique. the teeth were divided into two groups according to the irrigant used during root canal treatment: 5.25% sodium hypochlorite and nor...

The natural frequency and pull-in instability of clamped-clamped nano-actuators in the presence of a dielectric layer are analyzed. The influence of the presence of Casimir force, electrostatic force, fringing field effect, axial force, stretching effects and the size effect are taken into account. The governing equation of the dynamic response of the actuator is transformed in a non-dimensiona...

Objective. The aim of this study is to evaluate the factors that affect wearing time and patient behavior during reverse pull headgear therapy with a newly designed reverse pull headgear. Methods. In clinical practice, new reverse pull headgears were applied to fifteen patients. The patients were monitored during reverse pull headgear therapy and the data were evaluated. Statistical analysis wa...
