Proximal median neuropathy is uncommon. We report a case with left proximal median neuropathy due to compression of median nerve by ulnar artery at the proximal forearm. A 26-year-old woman complained left hand weakness without any sensory symptoms. Weakness was prominent in the distribution of anterior interosseous nerveinnervated muscles. Electrodiagnosis revealed proximal median neuropathy around the elbow and ultrasonographic study showed compression and splitting of median nerve by ulnar artery during pulsation.

Flow patterns around a rotating circular cylinder having Surface dimpled surface were visualized by the hydrogen bubble technique at velocity ratios from a=0 to 4.8 and Reynolds number of Re=l.0xl04. The wake region of the cylinder was reduced as the velocity ratios increase and was smaller than that of the smooth cylinder without dimples at the same velocity ratio. The hydrodynamic characteristics on the cylinder was investigated by measuring of lift and drag at velocity ratios from a =0 to 4.1 and Reynolds number from Re=1.2xl04 to Re=2.0xl04. As the velocity ratios increase. the average lift and drag coefficients were increased and at the same velocity ratio, the average lift was larger but the average drag was smaller than that of the smooth cylinder.<br/> <br/>
