The wheel, plow, and writing (a system which we call cuneiform) are examples of their achievements. The farmers in Sumer created levees to hold back the floods from their fields and cut canals to channel river water to the fields. The use of levees and canals is called irrigation, another Sumerian invention.
Histamine is the active amine responsible for the signs and symptoms encountered in an allergic reaction.
The outward signs of an allergic reaction are caused by histamine. This includes signs including a runny nose, wheezing, and swollen tissues. Mast cells release histamine during an allergic reaction, which causes allergy symptoms. Antihistamines attempt to halt the allergic reaction by blocking histamine activity.
Histamine is a significant cause of allergy illness and is primarily stored in mast cells and basophils. Histamine levels in the blood or tissues have been found to be higher during anaphylaxis and in animal models of allergic reactions to the skin, lungs, and nose.

Answer:
If isolationism has become outdated, what kind of foreign policy does the United States follow? In the years after World War II, the United States was guided generally by containment — the policy of keeping communism from spreading beyond the countries already under its influence. The policy applied to a world divided by the Cold War, a struggle between the United States and the Soviet Union.
With the collapse of the Soviet Union in 1991, containment no longer made sense, so in the past ten years, the United States has been redefining its foreign policy. What are its responsibilities, if any, to the rest of the world, now that it has no incentive of luring them to the American "side" in the Cold War? Do the United States still need allies? What action should be taken, if any, when a "hot spot" erupts, causing misery to the people who live in the nations involved? The answers are not easy.
