in petroleum production, produced water re-injection (pwri) has earned much interest among disposal methods of the produced water. however, presence of the contaminants in the produced waters usually results in formation damage in well bores and their surrounding fracture systems. in the present study, modeling of external cake formation on a fracture in unsteady-state conditions is discussed. ...

introduction: myelograghy is a process of instilling contrast medium to the subarachnoid space for evaluating the spinal column by radiography. there are various contrast solutions for different radiographic studies but not all of them are suitable for spinal column evaluation. conclusions: our subject recovered completely without any sequelae after receiving appropriate treatment in a multidis...

pink floyd was a british band whose work began in the late 60s. roger waters, the main contributor of the band, wrote almost all the lyrics and was also a main figure behind producing the motion picture of the album. he deliberately attacks western media in both the lyrics he has written for the band and his solo projects. the present study finds this tendency of assaulting the media deeply roo...

as narrative discourses and discursive thematic frame- works on social issues in media can provide us with an insight into how different understandings and perspectives serve to construct dif- ferent presentations of social actors, social events as well as social re- lations and conflicts, it seems necessary to take them into more seri- ous considerations. to this end, the present study was an ...

An increase in the flow velocity in flowthrough large porous media and deflection of flow regime from Darcy law causes a nonlinear relationship between hydraulic gradient and pore velocity of media. So many investigations have done previously in such Medias. One of the most important subjects in flowthrough large porous media is relationship between friction coefficient and flow characteristics...
