In physical chemistry and materials science, texture is the distribution of crystallographic orientations of a polycrystalline sample (it is also part of the geological fabric). A sample in which these orientations are fully random is said to have no distinct texture. If the crystallographic orientations are not random, but have some preferred orientation, then the sample has a weak, moderate o… WebThe Procurement Officer 1 performs purchasing and purchasing related functions for all GTA internal departments including purchase order creation, …
