What is Mixed: Definition and 270 Discussions

Mixed-use development is a term used for two related concepts:

In the sense of mixed-use zoning or mixed-use planning, it is a type of urban development, urban planning and/or a zoning type that blends residential, commercial, cultural, institutional, or entertainment uses into one space, where those functions are to some degree physically and functionally integrated, and that provides pedestrian connections. Mixed-use development may be applied in new real estate development projects in a city or suburb, or may apply to a single building, existing or new neighborhood, or in zoning policy across an entire city or other political unit.
In the sense of a mixed-use complex, mixed-use project, etc., a mixed-use development refers to "a development" — a building, complex of buildings, or new district of a community that is developed for mixed-use by a private developer, (quasi-) governmental agency, or a combination thereof. A mixed-use development may be new construction, reuse of an existing building or brownfield site, or a combination.

    Why Don't Gas Mixtures Segregate in a Sealed Container?

    As I understand, a gas mixture, say 50% C4H10 and 50% Air, will not segregate and form layers with the heavier gas at the bottom even in a sealed container. This is due to the constant movement of gas molecules. Is my understanding correct? Does this depend on pressure? Thanks
