Formation and Motion of Horse Collar Aurora Events

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

The UV aurora and ionospheric flows during flux transfer events

Far Ultra Violet (FUV) signatures in the polar ionosphere during a period of magnetopause reconnection are compared with ionospheric flows measured in the cusp ‘throat’ and dusk cell by the CUTLASS Hankasalmi HF radar. Regions of peak FUV emission in the 130.4 nm and 135.6 nm range, observed by the Polar spacecraft’s VIS Earth Camera, consistently lie at the turning point of the flows from the ...

motion events and the strategies of translating path: the case study of hobbit

1-introduction languages employ different strategies to represent motion as one of the basic human cognitive abilities. in talmy's typological dichotomy (1991; 2000b) languages are of two types according to the way they represent path either in verb roots or in satellites, accordingly languages are either verb framed or satellite framed. slobin (1991;1996 a,b.1997;2000) performed corpus based a...
