Human reproductive ecology to aid infant survival and growth. Lactational strategies vary cross-culturally, but can typically be defined by sibling sets and sex ratios, frequency of nursing, entire lactational duration, and milk composition. Milk is composed of my bioconstituents, but only a few will be outlined here. In the first days of puerperium, the first milk is thick and yellowish, also called colostrum. For weeks after that, mature milk is expressed and it has been shown that fetal-mammary gland signaling occurs even before birth in determining milk type and concentrations based on the fetus sex. Colostrum plays an important role in establishing the
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
