The articles in this volume provide a detailed review of all aspects of the main magnetic field of the Earth produced within the Earth's core: its past history, its long and short term changes, the way it is generated. The book contains the combined knowledge of geomagnetism coming from paleomagnetic and archeomagnetic data, centuries of terrestrial observations and from the past few decades of intensive space observations. There is considerable emphasis on the phenomenology and the physical processes of the evolution of the geomagnetic field on different timescales. The book reports fully on our understanding of the present state of the magnetic field and its expected evolution in the future.

The new edition of this established workbook consists of worked examples and set problems that cover one- and two-dimensional NMR techniques applied to organic and inorganic systems. Most of the problems are genuine research examples, and this new edition contains eight pages of problems drawn from very recent research work. This second edition is fully compatible with the second edition of the highly successful Modern NMR Spectroscopy: a guide for chemists, and the two books are thoroughly cross referenced throughout.

This book describes the coordination chemistry of macrocyclic ligands. Common types of ligands are introduced and strategies for the synthesis of the free ligands and their metal complexes are discussed. The unique thermodynamic and kinetic properties of macrocyclic complexes are introduced and applications of the ligands presented. The book is suitable for advanced undergraduate or graduate students and assumes a knowledge of organic and inorganic chemistry at the second year undergraduate level.

"If Information Is Power, Why Aren't We More Powerful? or Everything About Everything" is a futuristic tale about infocentricity and a young man with a nose for information and an inquiring mind. It is an inspirational text about information recycling and reuse. The premise is that today, enterprises don't know what they do know and, as a consequence, pay over and over in time, money and human energy to learn the same information. Today IT is 99% about technology and 1% about information. To change this will require a change to the underlying culture. When this change happens, we may even see corporate balance sheets including pre-positioned information as a corporate asset, much as inventories and other tangibles are valued. As today and tomorrow's youth make their transition to the work force, several issues arise, chief among which is the question: "Why would bright, young, computer literate people want to join enterprises that are in the technological and informational Dark Ages?" The purpose of this text is to show enterprise managers why they must reinvent their information husbanding approaches to overcome enterprise amnesia, not only to remain competitive in the information-efficient world of tomorrow, but also to attract and retain their next generation of talent. Companies like the author's firm, CAI/SISCo of Frederick, Maryland, have long been practicing what they preach and reaping the reward. Husbanding and leveraging pre-positioned information has reduced their competitive analysis and price to win (PTW) practice costs by at least 20%, allowing the enterprise to increase market share without increasing head count.
