By proper design of experiments, guided by a statistical approach, the effects of experimental variables may be found more efficiently than by the traditional approach of holding all variables constant but one and systematically investigating each variable in turn. Trends in data may be sought to track down nonrandom sources of error.

Rails for beef sides will be spaced 900-1200 mm apart, and the length for a side is 450 mm of rail. The height to the top of the rail may be up to 3.35 m, but may be less. The average side weight in the UK is 140 kg, with a variation of 80-225 kg throughout the world the local trend should be taken as a guide. Space is required for the service rails and junctions at the door end, possibly 1 m being taken up by this. Rails should be well clear of walls so that air can circulate and the meat cannot touch the wall. 

Numerous applications for biocides have been found in fields as diverse as ethical pharmaceuticals and cat litter products. The aim of this Cl book is two-fold to provide a comprehensive guide to the use of biocides across a range of applications and to aid in the selection of a biocide that is "fit for purpose". It covers a Cl cross-section of traditional measures, novel ideas and innovative developments, as well as addressing the biocides market, the political outlook and future trends of biocide use.
