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.
Positive form a unique connection preserving the Hermitian structure and satisfying This connection is called "the Chern connection". The curvature formula_16 of a Chern connection is always a purely imaginary (1,1)-form. A line bundle "L" is called "positive" if is a positive definite (1,1)-form. The Kodaira embedding theorem claims that a positive line bundle is ample, and conversely, any ample line bundle admits a Hermitian metric with formula_17 positive. Positive (1,1)-forms on "M" form a convex cone. When "M" is a compact complex surface, formula_19, this cone is self-dual, with respect to the Poincaré pairing :formula_20 For "(p, p)"-forms, where formula_21, there
