perturbing effect
41Perturbation theory — This article describes perturbation theory as a general mathematical method. For perturbation theory as applied to quantum mechanics, see perturbation theory (quantum mechanics). Perturbation theory comprises mathematical methods that are used to …
42Outdated theories of anaesthetic action — See the general anaesthetic page for current theories. A general anaesthetic (or anesthetic) drug is an anaesthetic drug that brings about a reversible loss of consciousness. These drugs are generally administered by an… …
43Kozai mechanism — In celestial mechanics, the Kozai mechanism is a secular perturbative effect on certain orbits. It causes changes in the eccentricity and the inclination of the orbit of the perturbed body to be periodic and synchronized, and also causes… …

49Bump mapping — is a computer graphics technique where at each pixel, a perturbation to the surface normal of the object being rendered is looked up in a heightmap and applied before the illumination calculation is done (see, for instance, Phong shading). The… …
50Myosin — Part of the myosin II structure. Atoms in the heavy chain are colored red on the left hand side, and atoms in the light chains are colored orange and yellow. Myosins comprise a family of ATP dependent motor proteins and are best known for their… …
