Kitten Within the first 2 days after birth, kittens acquire passive immunity from their mother’s milk. Milk within the first few days of parturition is called colostrum, and contains high concentrations of immunoglobulins. These include immunoglobulin A and immunoglobulin G which cross the intestinal barrier of the neonate. The immunoglobulins and growth factors found in the colostrum begin to establish and strengthen the weak immune system of the offspring. Kittens are able to chew solid food around 5–6 weeks after birth, and it is recommended that 30% of their diet should consist of solid food at this time. The kitten remains
Positive form are two different notions of positivity. A form is called strongly positive if it is a linear combination of products of positive forms, with positive real coefficients. A real "(p, p)"-form formula_22 on an "n"-dimensional complex manifold "M" is called weakly positive if for all strongly positive "(n-p, n-p)"-forms ζ with compact support, we have formula_23. Weakly positive and strongly positive forms form convex cones. On compact manifolds these cones are dual with respect to the Poincaré pairing. Positive form In complex geometry, the term "positive form" refers to several classes of real differential forms of Hodge type "(p, p)".
