In this study the centre manifold is applied for reduction and limit cycle calculation of a highly nonlinear structural aeroelastic wing. The limit cycle is arisen from structural nonlinearity due to the large deflection of the wing. Results obtained by different orders of centre manifolds are compared with those obtained by time marching method (fourth-order Runge-Kutta method). These comparis...

Purpose This study aims to propose and test a model that examines the potential connections between two teacher situational variables (teacher immediacy credibility) three learner affective factors (motivation, attitudes communication confidence) examine how such associations predict learners’ L2WTC (Foreign/second language willingness communicate) in class via comprehensive structurally verify...

objective(s):gemifloxacin is a broad spectrum antibiotic and has shown excellent coverage against a wide variety of microorganisms. in this study, an attempt was made to evaluate the immunomodulatory potential of gemifloxacin in male swiss albino mice in vivo. materials and methods: three doses of gemifloxacin 25 mg/kg, 50 mg/kg and 75 mg/kg were used intraperitoneally (ip) for the evaluation o...

Academic achievement is a function of many factors among which the school entry age has been controversial. Although the impact of the age factor is rather obvious, its effect is mediated by factors such a spiritual intelligence, social skills, and creativity. In order to devise a structural model by which the academic achievement can be predicted, a sample of 250 female 10th graders was select...
