Accurate estimate of flood flows at selected return periods is a fundamental step in flood control and design of hydraulic structures. Due to the inadequacy or unavailability of flood flow records in several western catchments of Iran, traditional regional flood frequency methods lead to remarkable estimate errors, particularly for long return periods. In this research, discriminant analysis is...

    Background and objectives: Halitosis as a common dentistry ailment which has a prevalence of around 50% of the adult population. There are many dental formulations in traditional Persian pharmacy called “Gharagher”, “Mazmazeh”, “Sonoun”, etc for treatment of halitosis. In the present study, we have tried to describe the step by step moder...

We apply the dressing method to a string solution given by a static string wrapped around the equator of a three-sphere and find that the result is the single spike solution recently discussed in the literature. Further application of the method allows the construction of solutions with multiple spikes. In particular we construct the solution describing the scattering of two single spikes and c...

A novel global optimization method referred to as the multi-step dynamic n-gram model is proposed for predicting the user’s next intended action while he/she is surfing the Web. Unlike the traditional n-gram model, in which the predicted action is taken as the ultimate goal and is only determined by its previous n actions, our method predicts the next action that lies on the optimal path that l...

Physicians’ daily need for valid information about diseases, their limited time for finding this information, the inadequacy of traditional sources (E.g. textbooks) to address this matter, the disparity between physicians diagnostic skills and clinical judgment (Which increase with experience) and their up to date knowledge and clinical performance (Which decline by time), as well as dramatic d...

Resuscitation of newborns is a critical procedure and requires refined skills. The contents of resuscitation guidelines and their implementation should be crucial in education of medical students. The traditional 2-stage (“see one, do one”) instruction is theory-loaded and does not provide sufficient hands-on training needed to give trainees the necessary practical experience or confidence in c...
