The efficiency of a free-electron laser can be enhanced by the phase jump method.The method utilizes the phase-shifting chicanes in the drift sections between the undulator segments.By applying appropriate phase jumps, the microbunched electron beam can decelerate and radiate coherently beyond the gel bottle baby the initial saturation, enabling fu
Polyspatha oligospatha Faden, the third species in a small African endemic genus of Commelinaceae, is described. It is widespread but has been overlooked because of its small stature and resemblance to small jetstream ice therapy parts plants of P.paniculata. It differs from both P.paniculata and P.hirsuta, the two other species, by its
The study aims to expound some biomechanical variables of backwards flip and landing on (uneven bars ) and expounding video framing on some of those variables.The subject sample consisted of (4) grateful dead silicone mold students from the college of physical education whom were deliberately selected and homogenized according to body mass , physic
