An Extremely rare case of periscaphoid and perilunate dislocation of the wrist is reported. The reported case is a young man with trauma following a motor cycle falling down. At first referral closed reduction and six weeks of long arm cast had been performed. The patient reffered to our hospital because of painful and limited range of motion. He underwent open reduction and internal fixatio...

Asymptotically exact and nonlocal fourth order nonlinear evolution equations are derived for two coupled fourth order nonlinear evolution equations have been derived in deep water for two capillary-gravity wave packets propagating in the same direction in the presence of wind flowing over water.We have used a general method, based on Zakharov integral equation.On the basis of these evolution eq...

This paper aims at presenting a new efficient element for free vibration and instability analysis of Axially Functionally Graded Materials (FGMs) non-prismatic beams using Finite Element Method (FEM). Using concept of Basic Displacement Functions (BDFs), two- node element extends  to three-node element for obtaining much more exact results using FEM. First, BDFs are introduced and computed usin...
