Colostrum Colostrum Colostrum (known colloquially as beestings, bisnings or first milk) is the first form of milk produced by the mammary glands of mammals (including many humans) immediately following delivery of the newborn. Most species will generate colostrum just prior to giving birth. Colostrum contains antibodies to protect the newborn against disease. In general, protein concentration in colostrum is substantially higher than in milk. Fat concentration is substantially higher in colostrum than in milk in some species, e.g. sheep and horses, but lower in colostrum than in milk in some other species, e.g. camels and humans. In swine, fat concentration of
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
