Low-energy ions of ionospheric origin constitute a significant contributor to the magnetospheric plasma population. Measuring cold ions is difficult though. Observations have to be done at sufficiently high altitudes and typically in regions of space where spacecraft attain a positive charge due to solar illumination. Cold ions are therefore shielded from(More)
The strength of five working muscle groups of the lower arms of 8 male fencers, including adductor pollicis, extensor carpi radialis, flexor carpi radialis, extensor carpi ulnaris, and flexor carpi ulnaris, were examined during competition. Root mean square values of muscular electromyographic signals indicated that the shape of foil handles significantly(More)
