91Protein domain — Pyruvate kinase, a protein from three domains (PDB 1pkn) A protein domain is a part of protein sequence and structure that can evolve, function, and exist independently of the rest of the protein chain. Each domain forms a compact three… …
92Grain boundary strengthening — (or Hall Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size. It is based on the observation that grain boundaries impede dislocation movement and that the number of dislocations within a …
93Ouzo effect — The ouzo effect during the preparation of absinthe. The ouzo effect (also louche effect and spontaneous emulsification) is a phenomenon observed when water is added to ouzo and other anise flavored liqueurs and spirits, such as pastis, raki, arak …

98Tooth development — Radiograph of lower right (from left to right) third, second, and first molars in different stages of development. Tooth development or odontogenesis is the complex process by which teeth form from embryonic cells, grow, and erupt into the mouth …
99Grain growth — refers to the increase in size of grains (crystallites) in a material at high temperature. This occurs when recovery and recrystallisation are complete and further reduction in the internal energy can only be achieved by reducing the total area… …
