This book had its genesis in a symposium on gas hydrates presented
at the 2003 Spring National Meeting of the American Institute of
Chemical Engineers. The symposium consisted of twenty papers
presented in four sessions over two days. Additional guest authors
were invited to provide continuity and cover topics not addressed
during the symposium. Gas hydrates are a unique class of chemical
compounds where molecules of one compound (the guest material) are
enclosed, without bonding chemically, within an open solid lattice
composed of another compound (the host material). These types of
configurations are known as clathrates. The guest molecules, u-
ally gases, are of an appropriate size such that they fit within
the cage formed by the host material. Commonexamples of gas
hydrates are carbon dioxide/water and methane/water clathrates. At
standard pressure and temperature, methane hydrate contains by
volume 180 times as much methane as hydrate. The United States
Geological Survey (USGS) has estimated that there is more organic
carbon c- tained as methane hydrate than all other forms of fossil
fuels combined. In fact, methane hydrates could provide a clean
source of energy for several centuries. Clathrate compounds were
first discovered in the early 1800s when Humphrey Davy and Michael
Faraday were experimenting with chlorine-water mixtures.

During World War II, the millions of letters American servicemen
exchanged with their wives and sweethearts were a lifeline, a vital
way of sustaining morale on both fronts. Intimate and poignant,
"Miss You" offers a rich selection from the correspondence of one
such couple, revealing their longings, affection, hopes, and fears
and affording a privileged look at how ordinary people lived
through the upheavals of the last century's greatest conflict.
