Permeability (spatial and transport planning) — Permeability or connectivity describes the extent to which urban forms permit (or restrict) movement of people or vehicles in different directions. The terms are often used interchangeably, although differentiated definitions also exist (see… … Wikipedia

permeability — /perr mee euh bil i tee/, n. 1. the property or state of being permeable. 2. Also called magnetic permeability. Elect. a measure of the change in magnetic induction produced when a magnetic material replaces air, expressed as a coefficient or a… … Universalium
permeability — /ˌpɜmiəˈbɪləti/ (say .permeeuh biluhtee) noun 1. the property or state of being permeable. 2. Physics a. the ratio of the magnetic flux density to the magnetic field present. b. the ratio of flux density produced in a material to that which would …
Mitochondrial permeability transition — Mitochondrial permeability transition, or MPT, is an increase in the permeability of the mitochondrial membranes to molecules of less than 1500 Daltons in molecular weight. MPT results from opening of mitochondrial permeability transition pores,… … Wikipedia
Mitochondrial permeability transition pore — The Mitochondrial Permeability Transition, or MPT, is defined as an increase in the permeability of the mitochondrial membranes to molecules of less than 1500 Daltons in molecular weight. MPT results from the opening of a mitochondrial… … Wikipedia
Vacuum permeability — This article is about the magnetic constant. For the analogous electric constant, see vacuum permittivity. Vacuum permeability, permeability of free space, or magnetic constant is an ideal, (baseline) physical constant, which is the value of… … Wikipedia
Chandrasekhar number — The Chandrasekhar number is a dimensionless quantity used in magnetic convection to represent ratio of the Lorentz force to the viscosity. It is named after the Indian astrophysicist Subrahmanyan Chandrasekhar. The number s main function is as a… … Wikipedia
Lundquist number — In plasma physics, the Lundquist number (denoted by S) is the dimensionless ratio of an Alfvén wave crossing timescale to a diffusion timescale. In SI units, it is given by:Sequivfrac{mu 0LV A}{eta},where L is a typical length scale, mu 0 is the… … Wikipedia
magnetic Reynolds number — ▪ physics combination of quantities that indicates the dynamic behaviour of a plasma. This number is analogous to the Reynolds number of ordinary fluid mechanics, which is used to determine whether or not a fluid flow will smooth out or… … Universalium
