The aim of present study was to enhance topical permeation of clotrimazole gel preparation by using various permeability enhancers such as coconut oil, pistachio oil and sodium lauryl sulphate (SLS). Clotrimazole gel preparations were prepared and optimized by using three factor, five level central composite design. A second-order polynomial equation was generated in order to estimate the effec...

A constant head permeability test of the coarse-grained soil an earth-rockfill dam was carried out and gradation tested determined based on continuous equation. Based results, empirical formula coefficient considering influence established. The can be used to assess with respect area under curve. applicability verified results from other studies. It found that suitable for soil. This paper prov...

Some experimental relations have been developed for determining the grout curtain depth, but these relations cannot be applied to any dam with any geological condition. Therefore, the effect of the grout curtain depth on seepage through foundation and abutments of each dam should be studied separately. To examine this parameter in Karun 4 dam, the numerical modeling method was applied using FLA...

reservoir permeability is a critical parameter for the evaluation of hydrocarbon reservoirs. there are a lot of well log data related with this parameter. in this study, permeability is predicted using them and a supervised committee machine neural network (scmnn) which is combined of 30 estimators. all of data were divided in two low and high permeability populations using statistical study. e...
