FOR AUTHORS
Formulae
- Leave ample space around the formulae.
- Subscripts and superscripts should be clear.
- Give the meaning of all symbols immediately after the equation in which they are first used.
- For simple fractions use the solidus (/) instead of a horizontal line.
- Equations should be numbered serially at the right-hand side in parentheses. In general only equations explicitly referred to in the text need be numbered.
- The use of fractional powers instead of root signs is recommended. Also powers of e are often more conveniently denoted by exp.
- Levels of statistical significance which can be mentioned without further explanation are * P<0.05, ** P<0.01 and *** P<0.001.
- In chemical formulae, valence of ions should be given, as, e.g., Ca2+, not as Ca++.
- Isotope numbers should precede the symbols, e.g. 18O.
- The repeated writing of chemical formulae in the text is to be avoided where reasonably possible; instead, the name of the compound should be given in full. Exceptions may be made in the case of a very long name occurring very frequently or in the case of a compound being described as the end product of a gravimetric determination (e.g. phosphate as P2O5).
