Digitalis lanata non-ionic substances in the leaves. The drought induced diminishing of photosynthesis is reversible after a few hours following watering of the plants. Drought stress also reduces the quantum yield of photosystem 2. More than 70 bitter glycosides with cardiac activity, with five different aglyconees digitoxigenin, gitoxigenin, digoxigenin, diginatigenin and gitaloxigenin in the leaves act as a protection against herbivores. Yield and concentration of these cardiac glycosides are enhanced by greenhouse cultivation through enhanced temperature and enhanced carbon dioxide concentration. "Digitalis lanata" contains a powerful cardiac glycoside that may be used by patients with heart conditions. Digoxin (digitalin) is a drug
Where Mathematics Comes From rethink a good deal of the philosophy of mind, epistemology, metaphysics, and the history of ideas. Where Mathematics Comes From Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being (hereinafter "WMCF") is a book by George Lakoff, a cognitive linguist, and Rafael E. Núñez, a psychologist. Published in 2000, "WMCF" seeks to found a cognitive science of mathematics, a theory of embodied mathematics based on conceptual metaphor. Mathematics makes up that part of the human conceptual system that is special in the following way: Nikolay Lobachevsky said "There is no branch of mathematics, however abstract, which may
