25Van Allen radiation belt — Van Allen radiation belts The Van Allen radiation belt is a torus of energetic charged particles (plasma) around Earth, which is held in place by Earth s magnetic field. It is believed that most of the particles that form the belts come from… …
26Fick's law of diffusion — Fick s laws of diffusion describe diffusion and can be used to solve for the diffusion coefficient D . They were derived by Adolf Fick in the year 1855. First law Fick s first law relates the diffusive flux to the concentration field, by… …
27Radiative transfer equation and diffusion theory for photon transport in biological tissue — Photon transport in biological tissue can be equivalently modeled numerically with Monte Carlo simulations or analytically by the radiative transfer equation (RTE). However, the RTE is difficult to solve without introducing approximations. A… …
