Gait bradykinesia and hypometria decrease as arm swing frequency and amplitude increase
(2018-11-20)
People with Parkinson's disease (PD) have decreased arm swing movements during walking, which can be related to PD motor signs and symptoms. In this context, the aim of this study was to determine the effects of an increased ...
The swing-by effect in the Vesta-Magnya case. Single and multiple encounters.
(2012-06-01)
It was verified that the asteroid Magnya has some physical and chemical characteristics similar to the bodies from Vesta family. However, astronomical observations revealed that Magnya is distant from these bodies. In the ...
