This paper focuses on the seismic evaluation of the Bell Towers of Lima’s Cathedral. The church, which dates back to 1535, has been modified and reconstructed several times over the centuries, changing its structural assembly in terms of lightening and strengthening. Focusing on the massive 45 m tall towers, linear kinematic analyses have been performed in order to evaluate their vulnerability. The results show how its actual performance is far below the safety requirements of the Peruvian code.

Objective: Alzheimer's disease is primarily characterized by cognitive decline; recent studies, however, emphasize the occurrence of motor impairment in this condition. Here, we investigate whether motor impairment, objectively evaluated with kinematic techniques, correlates with neurophysiological measures of the primary motor cortex in Alzheimer's disease. Methods: Twenty patients and 20 healthy subjects were enrolled. Repetitive finger tapping was assessed by means of a motion analysis system.
