Study on a New Environmentally Friendly Synthetic Fluid for Preparing Synthetic-Based Drilling Fluid
Colloidal Gas Aphrons (CGA), consist of gas bubbles with diameters ranging from 10 to 100 micron, surrounded by a thin aqueous surfactant film. This fluid combines certain surfactants and polymers to create the systems of microbubbles. The function of surfactant in CGAs is to produce the surface tension to contain the aphrons. Also, a biopolymer needs to be considered in the formulation as ...
Background and purpose: Because of the importance of early diagnosis of cervical cancer and high false negative results of conventional smear method, several studies have been performed to find a more appropriate test in recent years. Fluid-based methods especially thin prep are considered to have the highest potential to reduce the false negative results and to increase the adequacy of speci...
Among the many force s to which hydraulic structures are exposed to, the forces induced by cavitation incident are of typical hydrodynamic unknown forces. The aim of this study is to define these forces as coupled fluid-structure interaction under two dynamic effects. The first dynamic effect which incorporates facilities for dealing with cavitation fluid is based on the appearance and bursting...
Abstract Backgraound: Regarding the prevalence and high mortality rate of ovarian cancers, importance of markers to determine ovarian malignancies earlier, considerable experimental evidence about serum Gonadotropins to cyst fluid ratio with pathology of ovarian tumors and finally not enough experiments in our country, the present study was performed in Imam Hossein hospital between 2008 and...
Qaleh-Zari specularite-rich Cu-Ag-Au deposit is located 180 Km south of Birjand, in eastern Iran. Host rocks are mainly Tertiary calc-alkaline to K-rich calc-alkaline of 40.5±2 Ma and Jurassic sandstones and shales. Three major sub-parallel steep quartz veins are identified in different rock types, in particular andesitic rocks. The Qaleh-Zari deposit is a specularite-rich hydrothermal, Cu-Ag-A...
