41. Whereas an eigenaxis maneuver maintains a constant rotation axis and maneuver rate, a ZPM uses a time varying rotation axis and maneuver rate. 42. The first segment consists of two digits which are the priority numbers of the ligands on the five, six or sevenfold rotation axis . 43. Whereas an eigenaxis maneuver maintains a constant rotation axis and maneuver rate, a ZPM uses a time varying rotation axis and maneuver rate. 44. Carrington also determined the elements of the rotation axis of the Sun, based on sunspot motions, and his results remain in use today. 45. The spectrum does not vary over periods of hours or days . This indicates that the rotation axis must match the magnetic dipole axis. 46. Alternatively the reciprocal lattice points lie a long a cylinder with a constant \ xi value whose axis is coincident with the rotation axis . 47. The Coriolis force tends to organize fluid motions and electric currents into columns ( also see Taylor columns ) aligned with the rotation axis . 48. The rotation axis should be changed at least once, to avoid developing a " blind spot " in reciprocal space close to the rotation axis. 49. A wheel that is unbalanced on the center plane ( the plane orthogonal to the rotation axis ) causes a paralllel displacement of the axle. 50. The rotation axis should be changed at least once, to avoid developing a " blind spot " in reciprocal space close to the rotation axis .
