Another function of the jig is to steady the piece of wood being cut to prevent excess cutting or inaccurate cuts. The size, shape, and function of a woodworking jig will vary significantly according to how it is being used and with what tool it is being used.
WMAP image of the (extremely tiny) anisotropies in the cosmic background radiation. Anisotropy /ËÃ¦naÉªËsÉtrÉpi/ is the property of being directionally dependent, which implies different properties in different directions, as opposed to isotropy.
More recently, tests carried out in vivo (through MRI) and ex vivo (through mechanical testing of various cadaveric tendon tissue) have shown that healthy tendons are highly anisotropic and exhibit a negative Poisson's ratio in some planes when stretched up to 2% along their length, i.e. within their normal range of motion.
