Quark (dairy product) manufactured by "Dairyland". Quark may also be available as "baking cheese", "pressed cottage cheese", or "fromage frais". In Australia, Ukrainian traditional quark is produced by Blue Bay Cheese in Mornington Peninsula. It is also sometimes available from supermarkets labelled as quark or quarg. In New Zealand, European traditional Kwark is produced by Karikaas in North Canterbury. It is available in 350g pots and available online and in speciality stores such as Moore Wilsons. In the United Kingdom, fat-free quark is produced by several independent manufacturers based throughout the country. All the big four supermarkets in the UK sell their own
Current quark the formula_1-Scheme at formula_2 the quark masses are: A description is only possible with the help of relativistic quantum mechanics. The current quark mass is also called the mass of the 'naked' quarks. The mass of the current quark is reduced by the term of the constituent quark covering mass. The current quark mass is a logical consequence of the mathematical formalism of the quantum field theory (QFT), thus it is from a not descriptive origin. The current quark masses of the light current quarks are much smaller than the constituent quark masses. Reason for this is the missing of
