analysis of non-laminar flows in coarse alluvial beds has a wide range of applications in various civil engineering, oil and gas, and geology problems. darcy equation is not valid to analyze transient and turbulent flows, so non-linear equations should be applied. non-linear equations are classified into power and binomial equations. binomial equation is more accurate in a wide range of velocit...

wetlands, national parks and wildlife refuges are the most important ecological capitals, so inform of their change has main role in quality of management of such area. having new information of their changes helps us to find causes of changes and plans and policies that needed. remote sensing data are one of the most important and best sources for changes monitoring especially in environment. ...

Neuroimaging research indicates that human intellectual ability is associated to brain structure including the thickness of the cerebral cortex. Most studies show that general intelligence is positively associated with cortical thickness in areas of association cortex allocated throughout both brain hemispheres. Changes in cortical thickness over time have been related to intelligence, but whet...

In this work, adsorption of the potassium amyl xanthate collector on the pure chalcopyrite surface was studied by applying atomic force microscopy (AFM). The adsorption experiments were carried out at different concentrations of the collector and at diverse pH values in the presence or absence of exterior ions. The changes occurring in the surface morphology of chalcopyrite due to the collector...
