A note from the editor

Expert systems in solid-liquid separation have now gone out of fashion somewhat and the pre-selection of equipment now tends to be built into much larger design software. In any case, computerized advice, although helpful to complete beginners as a first approach, is no substitute for experience and in-depth knowledge of the subject.

The special multiracial issue of Amerasia Journal, discussed later in the chapter, provides a good example. The editors note The product of the interracial union is that apocalyptic monster about which the protectors of traditional racial classification warned their followers, those who clung to the belief that race is Black or White, that race can be pure that, in order to be racially correct and socially acceptable, one must run from the monster, demand conformity, and keep difference in the closet. That product is considered even more frightening if its multiracial composition includes African ancestry (Houston and Williams 1997, vii). At this late point in our discussion, it should hardly seem peculiar that the authors would refer genericaUy to protectors of traditional racial classification rather than... 

Leo Szilard was known by now throughout the American physics community as the leading apostle of secrecy in fission matters. To his mailbox, late in May 1940, came a puzzled note from a Princeton physicist, Louis A. Turner. Turner had written a Letter to the Editor of the Physical Review, a copy of which he enclosed. It was entitled Atomic energy from and he wondered if it should be withheld from publication. It seems as if it was wild enough speculation so that it could do no possible harm, Turner told Szilard, but that is for someone else to say. ... 

The elementary steps of this sequence could have been described separately in other parts of this chapter. However, this synthesis illustrates the possibilities of using sonochemical methods in various steps of a synthesis (Note from the Chapter Editor).

Note that the separate input sections are separated from one another by blank lines. These blank lines are inserted automatically into input files created with the Job Entry window in the Windows version and need not be entered by the user. If you choose to create a Gaussian input file using an external Windows editor, however, you must follow the same rules for input as under other versions of Gaussian. 

Some indication of the differences can be found by analysing some criticisms. .. upon the periodic classification solicited in 1881 by the editor of the Chemical News from Adolphe Wurtz, a celebrated Parisian chemist of the time.

While during the NATO-CARWC, the session on metal-air batteries featured other important contributions, it is, perhaps, by coincidence that only presenters from the former Eastern Block submitted their papers for this volume. In this regard, the editors wish to note, that papers below may be of special interest to the western reader, as they offer a rather unique insight into the science and application of the metal-air battery systems from the... 

In the introduction to Volume 1 of this series, the founding editors, J. N. Pitts, G. S. Hammond and W. A. Noyes, Jr. noted developments in a brief span of prior years that were important for progress in photochemistry flash photolysis, nuclear magnetic resonance, and electron spin resonance. A quarter of a century later, in Volume 14 (1988), the editors noted that since then two developments had been of prime significance the emergence of the laser from an esoteric possibility to an important light source, and the evolution of computers to microcomputers in common laboratory use of data acquisition. These developments strongly influenced research on the dynamic behavior of the excited state and other transients. 

With this Volume we note a change in Editors. Gunther von Biinau, who has recently retired from the University of Siegen has chosen this time to also retire from the Editorial Board of Advances. Gunther has been a strong contributor to the Series as we have collectively worked to make Advances a helpful literature asset. I will really miss working with him and wish him the very best in retirement.
