Milk product obtained from other mammals for consumption by humans of all ages. In almost all mammals, milk is fed to infants through breastfeeding, either directly or by expressing the milk to be stored and consumed later. The early milk from mammals is called colostrum. Colostrum contains antibodies that provide protection to the newborn baby as well as nutrients and growth factors. The makeup of the colostrum and the period of secretion varies from species to species. For humans, the World Health Organization recommends exclusive breastfeeding for six months and breastfeeding in addition to other food for at least two years.
Quadratic form is also called a quadratic form. Two "n"-dimensional quadratic spaces and are isometric if there exists an invertible linear transformation (isometry) such that The isometry classes of "n"-dimensional quadratic spaces over "K" correspond to the equivalence classes of "n"-ary quadratic forms over "K". Let "R" be a commutative ring, "M" be an "R"-module and be an "R"-bilinear form. A mapping is the "associated quadratic form" of "b", and is the "polar form" of "Q". Alternatively, a quadratic form may be characterized as follows: Two elements "v" and "w" of "V" are called orthogonal if . The kernel of a bilinear
