Braeburn during commercial long term storage, and it’s usually not possible to tell if an apple has the Braeburn browning disorder until a person bites or cuts into it. Apples respond dramatically to both temperature and atmosphere modification. Rapid temperature reduction and the exacting maintenance of low temperature close to the chilling point of the variety can provide good to medium quality product following 3 to 6 mo of storage and in some cases longer. However, modern commercial warehouses couple temperature management with controlled atmosphere (CA) for long-term storage of apples. Braeburn can be stored at 0 °C in air for
History of manifolds and varieties spaces with a differentiable or topological structure, while "variety" refers to spaces with an algebraic structure, as in algebraic varieties. In Romance languages, manifold is translated as "variety" – such spaces with a differentiable structure are literally translated as "analytic varieties", while spaces with an algebraic structure are called "algebraic varieties". Thus for example, the french word "" means topological manifold. In the same vein, the Japanese word "" (tayōtai) also encompasses both manifold and variety. ("" (tayō) means various.) Ancestral to the modern concept of a manifold were several important results of 18th and 19th century mathematics. The oldest
