Reindeer or even goat milk can also be used. Commercially available versions are typically made from cow's milk, and they lack some of the colour and flavour because of this. The cheese originally comes from Southern Ostrobothnia, Northern Finland, and Kainuu. The milk is curdled and set to form a round disk from two to three centimeters thick. After this, leipäjuusto is baked, grilled,
Prenex normal form "all" be written in universal-existential form, a special case of the prenex normal form that has every universal quantifier preceding any existential quantifier, so that all sentences can be rewritten in the form formula_79 formula_80 formula_81 formula_82 formula_83 formula_46, where formula_46 is a sentence that does not contain any quantifier. This fact allowed Tarski to prove that Euclidean geometry is decidable. Prenex normal form A formula of the predicate calculus is in prenex normal form if it is written as a string of quantifiers and bound variables, called the prefix, followed by a quantifier-free part, called the matrix. Every formula
