The Emerging Strategic Balance
light. Indubitably the strategic balance between the two super powers is the most important strategic equation obtaining today. What differentiates the nuclear forces of the super powers from other nuclear powers is not the overwhelmingly larger number of atomic weapons available with them, but their technological capability quickly to reach higher levels of sophistication which can be attained by other nuclear powers only with very great difhculty. Besides intercontinental missiles (ICBMs), multiple warhead systems (MIRVs) and anti-ballistic missile (ABM) systems, they have at present reconnaissance satellites, communication satellites and satellite inter-
Can Nuclear Deterrence Last Out The Century
The autumn of last year marked half the road from the beginning of the nuclear era to the year 2000. Mankind has been spared nuclear devastation since the annihilation of two Japanese cities by the only two nuclear weapons then existing. But the destructiveness of nuclear arsenals, now increased many thousandfold, has sunk into human consciousness like man’s knowledge of his mortality.
Wall-to-bed heat transfer in circulating fluidized beds
Heat Transfer from the wall of a circulating fluidized bed to the fast bed suspension has been investigated for several materials. The range of investigation includes dense and dilute phase fast fluidization and pneumatic transport. The overall heat transfer coefficient was found to be a function mainly of cross-sectional average suspension density. Effects of superficial velocity and solids mass flux were obscured by their interrelationship to the suspension density. Two models from the literature are evaluated using present and published data.
