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
Blake canonical form Blake canonical form In Boolean logic, a formula for a Boolean function "f" is in Blake canonical form (BCF), also called the complete sum of prime implicants, the complete sum, or the disjunctive prime form, when it is a disjunction of all the prime implicants of "f". The Blake canonical form is a disjunctive normal form. The Blake canonical form is not necessarily minimal, however all the terms of a minimal sum are contained in the Blake canonical form. It was introduced in 1937 by Archie Blake, who called it the "simplified canonical form"; it was named in honor of
