Abstract
In this research, uranium is leached from pHospHate ore of Sheikh Habil region by leaching operation using leaching agent (sulfuric acid) along with production of pHospHoric acid. In the following, the production of yellow cake from the produced liqueur solution (pHospHoric acid) by solvent extraction process is also mentioned. PHospHate ore contains a large amount of calcite and dolomite, which removal of these annoying elements by wet, dry and acid washing methods is the key to success in the production of pHospHoric acid. For this purpose, in the wet method of a flotation system, the dry method of heat furnace and in the acid washing method, various organic and inorganic acids were used...
Static and Dynamic Analysis of Cylindrical Vessel With Spherical Cap made of Functional Graded Materials Subjected to Seismic by Using Spherical and Cylindrical Superelements

Abstract
Recent developments in technology resulted in the design of functionally graded materials (FGM) in which properties can be changed gradually. One of the applications of these materials is in the pressure vessels. These materials can be used in a manner which minimize the heat loss and corrosion and maximize the strength. Most of the vessels include a cylinder and a hemispherical cap which used for the storage of liquid or gas. The vessels should be strength enough to handle high pressure as well as base vibration due to earthquake. Static and dynamic analyses of these structures must be performed prior to any application. In this project by utilizing finite element method and cylindrical...
