Indeed, the authors found that the system was so unstable that it simply cannot exist, with mean lifetimes of less than a thousand years across the whole range of plausible orbital solutions. Like other planetary systems proposed around similar evolved binary star systems, it seems likely that some mechanism other than claimed planets is responsible for the observed behaviour of the binary stars - and that the claimed planets simply do not exist.
 Question: planetary orbits around stars in binary systems are always unstable Context: Rescue from Gilligan's Island is a 1978 made-for-television comedy film that continues the adventures of the shipwrecked castaways from the 1964--67 sitcom Gilligan's Island, starring Bob Denver and Alan Hale, Jr., and featuring all the original cast except Tina Louise. The film first aired on NBC as a two-part special on October 14 and October 21, 1978. The film has the characters finally being rescued after 15 years on the island. The film was directed by Leslie H. Martinson.

Only two of the noble gases, helium and argon, are cost effective enough to be used in welding. These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Pure argon and helium are used only for some nonferrous metals. Semi-inert shielding gases, or active shield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. Most of these gases, in large quantities, would damage the weld, but when used in small, controlled quantities, can improve weld characteristics.
 Question: can you use nitrogen as a shielding gas for welding Context: The term National Mall commonly includes areas that are also officially part of neighboring West Potomac Park and Constitution Gardens to the southwest. The term is often taken to refer to the entire area between the Lincoln Memorial on the west and east to the United States Capitol grounds, with the Washington Monument dividing the area slightly west of its midpoint. A smaller designation sometimes referred to as the National Mall (proper) excludes both the Capitol grounds and the Washington Monument grounds, applying only to an area between them.

Minerals originate in the earth and cannot be made by living organisms. Plants get minerals from soil. Most of the minerals in a human diet come from eating plants and animals or from drinking water. As a group, minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids. The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. All of the remaining elements in a human body are called ``trace elements''. The trace elements that have a specific biochemical function in the human body are sulfur, iron, chlorine, cobalt, copper, zinc, manganese, molybdenum, iodine and selenium.
