Analytic solutions are presented for the orbit of a charged particle in the combination of a uniform axial magnetic field and parabolic electrostatic potential. These trajectories are shown to correspond to the sum of two individually rotating vectors with one vector rotating at a constant fast frequency and the other rotating in the same sense but with a constant slow frequency. These solution...

Introduction. Annular pancreas is a rare congenital anomaly in which band of the pancreatic tissue, continuity with head, completely or incompletely surrounds descending part duodenum. An abnormal development can cause complete annular pancreas, partial and divisum. Complete diagnosed newborns, while diagnosis more frequently established adults. The most reliable diagnostic methods are computed...
