In this paper, the self-focusing property of an intense circularly polarized laser pulse in hot magnetized plasma is investigated theoretically. First, an envelope equation governing the spot-size of the laser beam for both left- and right-hand polarizations has been derived in the presence of a planar wiggler. Furthermore, non-linear dispersion relation of laser pulse is obtained by using Maxw...

The purpose of this study was to investigate the effect of age and object location on the hand selection in reaching task 120 right-handed children, adolescents and adults were selected as aur as a participant. Handedness was determined by Stanley-corn (1992) handedness Questionnaire. The tasks included lifting, reaching, and making actual use of three different objects. After the participants ...
