A method, apparatus, and computer instructions for managing multi-threaded conversations in an instant messaging system. The FAMOS memory also includes an insulation transistor having a drain and a source respectively connected to the source of the insulated gate transistors of two adjacent cells of a same row. The apparatus may have a frame substantially configured as a bucket with a floor having front, middle, and rear sections, with the front and rear sections being fixedly attached to the side walls and the middle section being movable relative to the side walls to raise it above the front and rear sections to form a leveling bar. The partially to fully separated slurry is discharged into a pipeline and later into a hydrocyclone to effect a second phase separation of the slurry. The remote server immediately starts to interpret the user’s actions. The spacers are configured for being selectively disposed in the corresponding grooves.
