21Deformation mechanism — In structural geology, metallurgy and materials science, deformation mechanisms refer to the various mechanisms at the grain scale that are responsible for accommodating large plastic strains in rocks, metals and other materials. Contents 1… …
22Optical imaging — is an imaging technique. Optics usually describes the behavior of visible, ultraviolet, and infrared light used in imaging. Because light is an electromagnetic wave, similar phenomena occur in X rays, microwaves, radio waves. Chemical imaging or… …
23Spinodal decomposition — is a method by which a mixture of two or more materials can separate into distinct regions with different material concentrations. This method differs from nucleation in that phase separation due to spinodal decomposition occurs throughout the… …
24диффузионный пробоотборник — 3.6 диффузионный пробоотборник (diffusive sampler): Устройство для отбора проб газов и паров в воздухе с интенсивностью, обусловленной физическим процессом, например диффузией газа через неподвижный слой воздуха или пористый материал и/или… …

25Convection — This figure shows a calculation for thermal convection in the Earth s mantle. Colors closer to red are hot areas and colors closer to blue are cold areas. A hot, less dense lower boundary layer sends plumes of hot material upwards, and likewise,… …
26Advection — Advection, in chemistry, engineering and earth sciences, is a transport mechanism of a substance, or a conserved property, by a fluid, due to the fluid s bulk motion in a particular direction. An example of advection is the transport of… …
27Heat equation — The heat equation is an important partial differential equation which describes the distribution of heat (or variation in temperature) in a given region over time. For a function of three spatial variables ( x , y , z ) and one time variable t ,… …
28Amorphous computing — refers to computational systems that use very large numbers of identical, parallel processors each having limited computational ability and local interactions. The term Amorphous Computing was coined at MIT in 1996 in a paper entitled [http://www …
29Molecular diffusion — This article is about spontaneous dispersion of mass. For a more generic treatment of diffusion, see Diffusion. Diffusion from a microscopic and macroscopic point of view. Initially, there are solute molecules on the left side of a barrier… …
30Fick's laws of diffusion — For the technique of measuring cardiac output, see Fick principle. Molecular diffusion from a microscopic and macroscopic point of view. Initially, there are solute molecules on the left side of a barrier (purple line) and none on the right. The… …
