The Separation of Tungstic Oxide from Scheelite and its Subsequent Reduction with Hydrogen

The largest known deposits of tungsten ores occur in the continuation of the Indo-Malayan Mountains, which extends through Burma, Malaya, China, Japan, and Chosen. Production of tungsten concentrates was started in 1910 in Burma, and in 1911 this country was the world's largest producer. China produced but little until 1916, but has since supplied over fifty per cent of the world's requirements.

Risk Reduction Strategies: Past, Present, and Future

Physics and Science Policy Implications of Reduction of the U.S. Nuclear Weapons Arsenal

Maintaining the readiness U.S. nuclear weapons stockpile is a fundamental pillar of American defense policy. The biggest issue facing the national laboratories that are charged with this mission is replenishing the highly skilled and specialized manpower that is necessary for this task. This lecture presents both physics and science policy questions that must be answered. It also presents employment opportunities for young scientists and engineers.
