Yarns produced by Japanese Open-end BD-200 spinning machines give these major advantages: (1) They are somewhat stronger than yarns spun by Czecho BD-200's. (2) They are almost as strong as yarns spun by ring spinning machines. This strength is obtainable without raising the cost of raw cotton if the right fore-spinning processes and spinning conditions are used. (3) They have maximum strength ...

The history of the development of sound on film offers us lessons for the development of sound and music for interactive artforms. Now that technological developments have enabled almost unrestricted importation of audio into interactive platforms, the time has come for us to ask: is the content of the audio good enough?
