Overvoltage Analysis of Transmission Towers Considering the Influence of Tower-Footing Impedance
(Ieee, 2017-01-01)
Lightning is one of the main causes of outages due to backflashover mechanism in power systems. In this context, the tower-footing impedance presents a key role in the overvoltages caused by this phenomenon. Tower-footing ...

Chemical lumbar sympathectomy in plantar hyperhidrosis
(Springer Heidelberg, 2010-04-01)
Plantar hyperhidrosis can cause great changes to an individual's quality of life. We described a case successfully treated by the minimally invasive method of percutaneous injection of 7.0% phenolic solution into the lumbar ...
Text entry using a foot for severely motor-impaired individuals
(Association for Computing Machinery - ACMDongguk UniversityGyeongju, 2014-03)
Some individuals affected by a motor neuron disease lose voluntary movement of the torso and arms, but keep for some time at least a partial movement of a leg and a foot. This work presents DuoGrapher, a text entry method, ...
