Abstract:
Changes in atmospheric pressure have been reported to cause a transient lower motor neuron weakness of the facial nerve. We report the case of a passenger on an international flight who developed a unilateral facial weakness after take-off which resolved within 45 min. The effect is thought to be due to an ischaemic neuropraxia of the facial nerve caused by increased middle ear pressure compressing the facial nerve in an exposed facial canal. The condition has been commonly reported in scuba-divers but less frequently in airline passengers. Treatment is not necessary.

Work Done Over an Inclined Plane
The work done by gravity to move a rigid body, or the work done by an opposing force to move a rigid body against gravity, can be calculated using the center-of-mass framework. It is the line integral of the force of gravity over the path, considered positive if...
