Viruses transmitted by nematodes are responsible for many economically important diseases of crops. Thus, when in the late 1950s, this mode of disease propagation was demonstrated by proof of the transmission of grapevine fanleaf disease by Xiphenema index. It marked the start of a significant and fruitful period of research. After the initial enthusiasm associated with the discovery of new vectors and new viruses, there followed a spell of consolidation in which researchers sought the answers to intriguing questions about the nature of the association between virus and vector, as well as more mundane, but equally compelling questions about life-cycles, geographical distribution and the taxonomy of groups of vector species. With the introduction of molecular biology, new approaches became available with which to investigate nematode-virus-plant interactions and these techniques are being exploited to provide new insights. Numerous reviews have been published on different aspects of nematode transmission of plant viruses and the nematode transmitted viruses themselves. However, until now there has been a lack of any source which draws all of this research together. This book fills this need by providing a valuable overview of the last 40 years of research into the transmission of viruses by nematodes as well as setting the agenda for future investigations. This book is an important resource for all nematologists and plant virologists, as well as others concerned with crop protection.

The term "artificial life" describes research into synthetic systems that possess some of the essential properties of life. This interdisciplinary text includes looking at the field in an attempt to understand high-level behaviour from low-level rules.

Meditations on Gratitude is an affirmation of life, the eternal yes, and the voice of one returning to foundations of responsibility, love, and understanding often learned in adolescent experience. The poems depict growth from solipsism, preoccupation with pain and fear, to acceptance, and surrender. They allow the personae growth in recognition of death. Some understandings came out of my association with Armida Alexander, my Unitarian Universalist minister, and fulfillment of my roles as husband and father. The poems depict a new assumption of responsibility sometimes through simple awareness of the words “please,” and “thank you.” Thus, the poetic voice becomes one of gratitude, and an affirmation of life, life as a great gift, for as Jon Kabat-Zinn has said stated in his book Full Catastrophe Living, “as long as one is breathing, one is doing something right.” In meditation, both Theravada and Mahayana Buddhist traditions emphasize breath, and often beginning meditation starts with simple breath counting. From this comes insight, and this is the point of Meditations on Gratitude, the insight of life as in the Buddha turning after attaining Enlightenment to the earth, and breath became essence. Christians would call this the “breath of life.”

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.
