Hammer speed at release is one of the most important factors contributing to the distance of a hammer throw. Hammer speed follows a generally increasing trend during the throw, with one fluctuation pe...
Ground reaction force and wire tensile force were measured during test throws by three hammer throwers: the Asian record holder, who had a personal best of 83.47 m at the time of the investigation, an...
After a brief discussion of data analysis methods, this paper reviews new results and open questions on the structure of the quiet corona. The formation of the helium spectrum is discussed, and some o...
