Article: Uranium is used as a colorant in uranium glass producing orange-red to lemon yellow hues. It was also used for tinting and shading in early photography. The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus. Eugene-Melchior Peligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Henri Becquerel. Research by Otto Hahn, Lise Meitner, Enrico Fermi and others, such as J. Robert Oppenheimer starting in 1934 led to its use as a fuel in the nuclear power industry and in Little Boy, the first nuclear weapon used in war. An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used uranium metal and uranium-derived plutonium-239. The security of those weapons and their fissile material following the breakup of the Soviet Union in 1991 is an ongoing concern for public health and safety. See Nuclear proliferation.

Question: What was the first nuclear weapon used in a war called?
Ans: Little Boy

Article: During fiscal year 2007, $537.5 million was received in total research support, including $444 million in federal obligations. The University has over 150 National Institutes of Health funded inventions, with many of them licensed to private companies. Governmental agencies and non-profit foundations such as the NIH, United States Department of Defense, National Science Foundation, and NASA provide the majority of research grant funding, with Washington University being one of the top recipients in NIH grants from year-to-year. Nearly 80% of NIH grants to institutions in the state of Missouri went to Washington University alone in 2007. Washington University and its Medical School play a large part in the Human Genome Project, where it contributes approximately 25% of the finished sequence. The Genome Sequencing Center has decoded the genome of many animals, plants, and cellular organisms, including the platypus, chimpanzee, cat, and corn.

Question: What percentage of the sequencing did the Washington University Medical School contribute to the Human Genome Project?
Ans: 25%

Article: The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case.

Question: What is the net quality of the ground dependent of?
Ans: topography

Article: Until 2005, the United Nations General Assembly annually adopted a detailed resolution about the situation in Myanmar by consensus. But in 2006 a divided United Nations General Assembly voted through a resolution that strongly called upon the government of Myanmar to end its systematic violations of human rights. In January 2007, Russia and China vetoed a draft resolution before the United Nations Security Council calling on the government of Myanmar to respect human rights and begin a democratic transition. South Africa also voted against the resolution.

Question: What other countries were in disagreement with the United Nations decision on Burma ?
Ans:
South Africa
