Colostrum immune cells (as lymphocytes) and many antibodies such as IgA, IgG, and IgM. These are some of the components of the adaptive immune system. In preterm infants some IgA may be absorbed through the intestinal epithelium and enter the blood stream though there is very little uptake in full term babies. This is due to the early "closure" of the intestinal epithelium to large molecule uptake in humans unlike the case in cattle which continue to uptake immunoglobulin from milk shortly after birth. Other immune components of colostrum include the major components of the innate immune system, such as lactoferrin,
Sesquilinear form form, it follows that, for all , It also follows that is a fixed point of the map . The fixed points of this map from a subgroup of the additive group of . A -Hermitian form is reflexive, and every reflexive -sesquilinear form is -Hermitian for some . In the special case that is the identity map (i.e., ), is commutative, is a bilinear form and . Then for the bilinear form is called "symmetric", and for is called "skew-symmetric". Let be the three dimensional vector space over the finite field , where is a prime power. With respect
