Various mechanisms such as gravitational separation, flocculation, coalescence, and Ostwald ripening result in instability. There are four types of instability in emulsions&colon; flocculation, creaming/sedimentation, coalescence, and Ostwald ripening. By promoting coalescence of small water droplets, the settling rate can be greatly increased. Fast fracture occurs through a process of microvoid coalescence where failures initiate around inter-metallic particles. It is also used in oil-in-water emulsions to enhance droplet coalescence. Each of these processes leads to coalescence or merging of steel components into pipes. Subsequent zooid replication can lead to coalescence and circulatory fusion of the subcolonies. Its formation is with two patterns&colon; coalescence and division. Decreased bubble coalescence leads to smaller bubble sizes and greater foaming ability in water. Hence Cr provides additional evidence for nucleosynthetic processes immediately before coalescence of the Solar System. Coalescence of coastal fog accounts for a considerable part of the trees' water needs. The effective population size is most commonly measured with respect to the coalescence time. A coalescer is a technological device performing coalescence. Some of Williams's compositions were played on the albums "Coalescence" and "Jazzblues".
