The author explains the clinical presentation, pathophysiology, prevention, diagnostic work-up, and management of bilateral vestibulopathy. Gait ataxia and oscillopsia are the key clinical features of bilateral vestibulopathy. Other clinical features of bilateral vestibulopathy include absence of spontaneous vertigo and nystagmus; inability to walk in the dark or on uneven or soft surfaces, unl...

Locomotion is a natural task that has been assessed for decades and used as a proxy to highlight impairments of various origins. So far, most studies adopted classical linear analyses of spatio-temporal gait parameters. Here, we use more advanced, yet not less practical, non-linear techniques to analyse gait time series of healthy subjects. We aimed at finding more sensitive indexes related to ...

THE GALVANIC CELL The major corrosion concern in the water works industry is “galvanic” corrosion. Galvanic corrosion takes place due to current flow in a “galvanic cell” which is defined as (1) two dissimilar metals, an anode and a cathode, (2) in electrical contact with each other and (3) a common electrolyte. A galvanic cell is produced when the pipeline components come in contact with the s...
