Given a Hausdorff topological space M with differential structures 𝒜₁ and 𝒜₂ (these being maximal smooth atlases), we say that 𝒜₁ and 𝒜₁ are equivalent if there is a diffeomorphism 𝜙:(M,𝒜₁)→(M,𝒜₂) from M with the first differential structure to M with the second differential structure. Note that 𝜙 need not be the identity function.

In quality synergistic additives in a composition use oxide antimonies.

Always making notes to myself I am, but never reading the damn things back. Which is why I am always on the floor, my table of a waiter of a lover-man, mine.

The composition of the venoms of the first three is dominated by short (3–9-kDa) disulfide-rich peptides that contain the inhibitor cysteine knot (ICK) motif, although heavier proteins, including enzymes, are also present. ICK peptides are structurally very stable and mainly target the nervous system, acting primarily on membrane channels or neuronal receptors.
