Magnetic Properties of Rare Earth Metals


Book Description

The rare earths have a unique place among the elements. Although very much alike chemically and in most phy~ical properties they each have very different and striking magnetic properties. The reason, of course, lies in their 4f electrons which determine the magnetic properties but have little effect on other chemical and physical behaviour. Although they are not rare, some indeed are among the more common heavy elements in the earth's crust, the difficulty of separation has meant that their intricate magnetic properties have only recently been unravelled. Now, however, the general pattern of their magnetism is well charted and the underlying theory is well understood. Both are thoroughly summarised in this book. It provides an excellent example of the kind of extensive synthesis which is possible with modem solid state physics. it represents only a high plateau in the ascent to complete understanding. But It will become clear to the reader that while the overall position is satisfactory there are many details still to be elucidated experimentally and much to be done theoretically before all the underlying forces are identified and estimated from a priori calculations. It is hoped that the book will provide a useful stimulus in this direction. It should also be of use to those who are interested in related disciplines, for example the rare earth compounds, or the transition metals. In addition rare earths promise to be important technologically as alloy constituents.




Hidden Waters of New York City


Book Description

A guide to the forgotten waterways hidden throughout the five boroughs Beneath the asphalt streets of Manhattan, creeks and streams once flowed freely. The remnants of these once-pristine waterways are all over the Big Apple, hidden in plain sight. Hidden Waters of New York City offers a glimpse at the big city’s forgotten past and ever-changing present, including: Minetta Brook, which ran through today's Greenwich Village Collect Pond in the Financial District, the city's first water source Newtown Creek, separating Brooklyn and Queens Bronx River, still a hotspot for urban canoeing and hiking Filled with eye-opening historical anecdotes and walking tours of all five boroughs, this is a side of New York City you’ve never seen.

Diagrammatic Representation and Inference


Book Description

This book constitutes the refereed proceedings of the 10th International Conference on the Theory and Application of Diagrams, Diagrams 2018, held in Edinburgh, UK, in June 2018. The 26 revised full papers and 28 short papers presented together with 32 posters were carefully reviewed and selected from 124 submissions. The papers are organized in the following topical sections: generating and drawing Euler diagrams; diagrams in mathematics; diagram design, principles and classification; reasoning with diagrams; Euler and Venn diagrams; empirical studies and cognition; Peirce and existential graphs; and logic and diagrams.
