Units, symbols and abbreviations in the Proceedings

I. McCance, Past APPS Editor, 3 Judith Court, Mount Waverley, Victoria 3149, Australia.

The previous abstracts make reference to Baron (1988) as the source of information for units, symbols, abbreviations and conventions that should be used in the "Proceedings". To simplify the authors' tasks, some of this information is abstracted here.

Units: SI units should be used. Baron (1988) lists SI Base Units (e.g., kilogram, (kg)), prefixes for SI Units (e.g., milli (10-3), micro (10-6), nano (10-9)), SI derived units with special names (e.g., newton, N, = kg m s-2), and non-SI units accepted for general use (e.g., litre, l or L (see footnote to Table), = 1×10-3 m3.

Derived units should be written sequentially, e.g., ml kg-1 min-1 as in Regan et al. (1994), with no full stop between. Where only two terms are involved, the solidus may be used, e.g., mol/l or mol l-1.

Symbols and Abbreviations: Abbreviations should be defined in the text of the abstract, not in the title.
Times: s, min, h, d; prefer not to abbreviate week, month, year.
Statistics: x, SD, SE (see McCance, 2001), P, r, t, χ2. Always indicate d.f. where appropriate.
Routes of administration: i.v., i.p., i.m., i.c.v.

ampere A diameter diam. logarithm to base e loge or ln
anterior ant. editor(s) ed. maximum max.
calculated calc. experiment expt. minimum min.
compare cf. extracellular fluid e.c.f. page/pages p./pp.
compliance (resp.) C similarly, i.c.f.,p.c.v. or PCV, r.b.c. or RBC, r.m.s.,w.b.c. or WBC relative humidity r.h.
counts per minute ct/min haemoglobin Hb temperature temp.
concentration of substance shown as formula [ ] increment Δ revolutions per minute rev/min
cycles per second Hz litre l or L volume vol.

Note: Baron allows l, L as alternatives. Authors should be consistent.

Approximation: use approx. (or ≈) for measurements. The Latin word circa (c or ca) should be reserved for dates.
