Abstract We consider solitary-wave solutions of the generalized Burger’s-Fisher equation ∂Ψ ∂t + αΨ δ ∂Ψ ∂x − ∂ 2Ψ ∂x2 = βΨ(1 − Ψδ). In this paper, we present a new method for solving of the generalized Burger’s-Fisher equation by using the collocation formula for calculating spectral differentiation matrix for Chebyshev-Gauss-Lobatto point. To reduce round-off error in spectral collocation met...

Aims: Depression is a common psychiatric disorder after myocardial infarction. So it is necessary to find the appropriate intervention to reduce depression. This study aimed at comparing the effect of eye movement desensitization and reprocessing (EMDR) and cognitive behavioral therapy (CBT) on depression in patients with myocardial infarction. Materials & Methods: In this clinical trial, 90 e...

Background: Abnormal levels of the markers AFP, hCG, and uE3 could be useful in predicting adverse pregnancy outcomes. This study was designed to determine the correlation between second trimester maternal serum markers and adverse pregnancy outcome (APO). Methods: In this historical cohort study, we randomly followed 231 obstetric patients with quadruple screening test in 14-18 weeks of ges...

introduction: it was to compare the efficacy of semiannually fluoride varnish application versus pit and fissure sealant to reduce occlusal caries incidence. materials and methods: a randomized parallel designed study was conducted with 352 child-ren aged 6-7 years. participants were allocated into biannual application of varnish (n=179) (naf 5 %( durafluor, dentsply®, latin america) or resin-b...

The outcome of any medical research is belonged to the human beings. correct application statistical test has its paramount importance. This article provides details categorical data analysis with example and interpretation. It included when use Chi-square (2*2 & R*C), Yate`s Correction, Fisher Exact test, Mc Nemartest manually as well using Open Epi R codes.

The conventional approach for testing the equality of two normal mean vectors is to test first the equality of covariance matrices, and if the equality assumption is tenable, then use the two-sample Hotelling T (2) test. Otherwise one can use one of the approximate tests for the multivariate Behrens-Fisher problem. In this article, we study the properties of the Hotelling T (2) test, the conven...

objective: this study compared the tension-free vaginal tape (tvt) and transobturator tape (tot) procedures for surgical treatment of stress urinary incontinence in women. materials and methods: this prospective non randomized clinical trial was conducted in vali-e-asr hospital from march 2001 to march 2005. a total of 71 patients with clinical and urodynamic diagnosis of stress urinary inconti...
