Leipäjuusto Leipäjuusto Leipäjuusto (bread cheese) or juustoleipä, which is also known in the United States as Finnish squeaky cheese, is a fresh cheese traditionally made from cow's beestings, rich milk from a cow that has recently calved. 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,
Polar form of the Dirac equation formula_11 vanish simultaneously, the spinor field is called regular, and in this case it is always possible to find a local frame in which the regular spinor field acquire the form up to a transformation of the type formula_15 and up to the reversal of the third axis. Therefore, a regular spinor can, in general, be written according to where formula_17 is called module and formula_18 is called Yvon-Takabayashi angle, and where formula_19 is the generic complex representations of the Lorentz transformation that is needed to obtain the generic spinor in its most reduced form as is written above.
