We research about Japanese sparkler 'senkoh-hanabi' combustion under microgravity. Present 'senkoh-hanabi' studies report only qualitative analysis. Then we develop method of quantitatively analyze about 'senkoh-hanabi'. This method can show 'senkoh-hanabi' spark distribution by integrating video image. Using this method; we clear 'senkoh-hanabi' spark distribution is symmetry around fire ball.

The quality of large semiconductor crystals grown from silicon melts is significantly affected by the heat and mass transfer in the melt. The characteristics of silicon flows are reviewed by focusing on the Coriolis force in the rotating melt. Description of flow instability is included that shows our level of understanding of melt convection with a low Prandtl number.
