The importance of formalising the speciication of standards has been recognised for a number of years. This paper advocates the use of the formal speciication language Object-Z in the deenition of standards. Object-Z is an extension to the Z language speciically to facilitate speciication in an object-oriented style. First, the syntax and semantics of(More)

The technique of rapid evaporation of whole urine to standard osmolality has been studied further and quantitative measurements made of the calcium oxalate crystals resulting, firstly by a microscope method and secondly by isotope method using 14C-oxalate. It is confirmed that ultrafiltration of urine prior to evaporation leads to a large reduction in(More)
The social characteristics of 809 couples attending a sex preselection clinic have been studied. Their ethnic origins were: Indian 57.8%, European 32.0%, Chinese 3.6% and others 6.8%. The average number of boys and girls per family was 0.09 and 2.70 respectively for couples wanting a boy, and 2.46 and 0.14 for those wanting a girl. The average age of the(More)
A method for the determination of human plasma oxalate concentration by an enzymatic assay procedure is described using deproteinised plasma. The apparent concentration of oxalate in 20 normal subjects was 1.1--16.0 mumol/l (mean 7.78; S.D. 3.96). It was suspected that these results might be too high, due to the possible conversion of glyoxalate to oxalate,(More)
