Despite the fact that there are wastewater treatment plants (WWTPs) currently operational across Iran and great advances have been made in this area, there are still problems in the design, construction, and operation of WWTPs with large nonlinear systems, varying flow rates, and pollution charges. The objective of this study was to investigate the effect of operating parameters including the r...

Mammalian Ras GTPase-activating protein (GAP), p120 Ras-GAP, has been implicated as both a downregulator and effector of Ras proteins, but its precise role in Ras-mediated signal transduction pathways is unclear. To begin a genetic analysis of the role of p120 Ras-GAP we identified a homolog from the fruit fly Drosophila melanogaster through its ability to complement the sterility of a Schizosa...

statement of problem: recurrent aphthous stomatitis (ras) is one of the most common diseases affecting the oral mucosa. many topical and systemic medications used to treat ras have adverse local and systemic effects. chamomill (kamillosan) has been shown to be an effective drug, without any noticeable side effects. purpose: the aim of present study was to assess the efficacy of a chamomill mout...

The brain renin-angiotensin system (RAS) has long been considered pivotal in cardiovascular regulation and important in the pathogenesis of hypertension and heart failure. However, despite more than 30 years of study, the brain RAS continues to defy explanation. Our lack of understanding of how the brain RAS is organized at the cellular and regional levels has made it difficult to resolve long-...

A methodology based on adaptive ANN models is proposed for flood routing in river systems. The proposed methodology is capable of modeling both converging and diverging river networks. A Multilayer Perceptron Network (MLP), a Recurrent Neural Network (RNN), a Time Delay Neural Network (TDNN) and a Time Delay Recurrent Neural Network (TDRNN) are applied in this study. An Adaptive training proced...

A new methodology was developed for the real-time determination gate control operations of a river-reservoir system to minimize flooding conditions. The is based upon an optimization-simulation model approach interfacing genetic algorithm within MATLAB with simulation software short-term rainfall forecasting, rainfall–runoff modeling (HEC-HMS), and one-dimensional (1D), two-dimensional (2D), co...

This study presents an advanced remote sensing-based steady-state flood model to improve flood management strategies. The REFIX (Regression and Elevation based Flood Information eXtraction) model is based on regression analysis and uses a remotely sensed flood extent and a high-resolution floodplain DEM (Digital Elevation Model) to estimate water heights for a given flood event. In some cases, ...

statement of the problem: recurrent aphthous stomatitis (ras) is one of the most common lesions in the oral cavity. due to its multifactorial nature, there is no definitive treatment for ras. laser therapy is one of the suggested treatments to reduce patient’s discomfort. purpose: the purpose of the present clinical trial is to assess the effect of low and high level laser therapy on pain contr...
