Notes on the structure of the glossary

·       All units are expressed as SI units unless otherwise indicated.

·       The entries are in simple alphabetical order, with spaces and punctuation marks, such as hyphens, ignored.

·       Acronyms per se are included in their alphabetical position in the text.  Greek characters have been spelled out in full (e.g. alfa instead of a).

·       All the words in the definitions that are reported in bold are themselves defined terms (or their plurals).
