The stomach has an internal lining, or mucous membrane, called the gastric mucosa. The mucosa must create hydrochloric acid to break down food, but also protect itself from the acidic contents that it creates. This delicate balance is controlled by three different glands in the lining of the stomach.
The IMF, the SDR, and the Dollar: One Big Happy. The SDR is a fake currency issued by the International Monetary Fund. It was invented in 1969, the first year of the Nixon administration. It was a stop-gap measure to save the fixed exchange rate system of currencies, which came into existence in 1946, when the 1944 Bretton Woods system was implemented.
Initially, the value of the SDR was defined in terms of one US-$, which in turn was defined in terms of an ounce of gold: $35/oz until 18-Dec-1971; $38/oz between 18-Dec-1971 and 11-Feb-1973; $42.22/oz between 12-Feb-1973 and 30-Jun-1974.Since July 1974 the SDR has been defined in terms of a basekt of currencies.he exchange rates used by the IMF to calculate the official SDR are the noon rates in the London foreign exchange market. When the London market is closed, noon rates in the New York market are used, and Frankfurt fixing rates are employed when the New York market is also closed.
