America has no official royalty by design. Yet there have been the Roosevelts, the Adams, the Bushes, the wanabee Clintons and most intriguing of all -- the Kennedys. The Kennedys have so far only reached the presidency once but the assassination of JFK and his brother Robert, and the trials and tribulations of the family members and society in general continue to fascinate the world. This new book presents more than 1200 citations of books and related materials arranged by family member. The accompanying CD-ROM offers ready access and easy searching.
Experimental evidence regarding pressure gradients in Bridgman anvil devices is reviewed and some new experimental data are presented. Although there are many differences in details, all the experimental evidence is found to fit a general pattern. A simple empirical relationship describing the pressure distribution is derived which is consistent with experimental observation. The experimentally determined pressure is used to estimate errors introduced into various types of anvil experiments by pressure gradients. Numerical values for the correction factors are given in graphical form for a wide range of experimental conditions. Analysis of shear experiments indicates that pressure gradients are much smaller under dynamic conditions. Analysis also shows that the peripheral sample region which is partially nonload-supporting frequently has a greater detrimental effect on anvil experiments than does the pressure gradient which exists over the central portion of the sample cell.
