A prototype elliptical polarization from bending magnet ( EPBM) system with a dynamic local bump has been implemented at the SRRC storage ring. The local bump is created by using two pairs of vertical correctors located on each side of the bending. The bump strength coeffieient was obtained from measured beam response matrix. Disurbance of stored electron beam orbit was boserved while flipping ...

The limited performance of pure glassy and rubbery polymeric membranes for natural gas purification are due to their intrinsic properties. Optimizing properties by blending both polymers expected address the shortage. foremost objective this research is synthesis enhance polymer blend (EPBM) using polysulfone (PSU) polyvinyl acetate (PVAc) with addition amine carbon dioxide (CO2) removal from m...

foam injection is becoming a standard conditioning agent when tunnelling with an earth-pressure balanced shield, resulting in an increasing interest in this technique. the technique is mostly based on empirical rules and experience. to be able to determine what foam and how may foam has to be injected for different soils, it is necessary to know the mechanical parameters of the foam-water-soil ...
