Abstract:
The proliferation of electric scooters in urban areas is responsible for a growing number of serious injuries to the head and mostly to the face. The risk factors are related to the design of the machines, the user, the sharing of public space in urban centers and the lack of respect for prevention rules. Each one of these parameters deserves corrections to be applicable in this social phenomenon.

Charging Conductors By Induction
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...
