Geography of Uzbekistan in power but also to the very survival of Uzbekistan, the increasingly grave environmental threat will not be addressed effectively. The Government of Uzbekistan joined forces with Kazakhstan, Turkmenistan, Tajikistan, and Kyrgyzstan in 1992 to form the International Fund for Saving the Aral Sea (IFAS) and in 1993 to form the Interstate Council on the Problems of the Aral Sea Basin (ICAS). The ICAS was formed to work with the World Bank in order to improve the conditions of the Aral Sea, but was disbanded in 1997 to form IFAS.

Disappearing-filament pyrometer Disappearing-filament pyrometer The disappearing-filament pyrometer is an optical pyrometer, in which the temperature of a glowing incandescent object is measured by comparing it to the light of a heated filament. Invented independently in 1901 by Ludwig Holborn and Ferdinand Kurlbaum in Germany and Harmon Northrup Morse in the United States, it was the first device which could measure temperatures above 1000°C. Disappearing filament pyrometers have been used to measure temperatures between about 600°C and 3000°C. Like other optical pyrometers they are used to measure the temperature of objects too hot for contact thermometers, such as molten metals. Widely used in
