The aim of this study was to provide standards for the assessment of birthweight, head circumference and crown-heel length for normal, singleton newborns of predominantly West African descent. Data were collected for 10 482 or 94% of all recorded births in Jamaica during the two-month period September 1 to October 31, 1986.

A growth chart for girls with Turner syndrome has been prepared using data from four published series of European patients, and evaluated using retrospective data on the heights of girls with Turner syndrome seen at this hospital. The results indicate that calculation of height standard deviation score from this chart allows a reasonable prediction of adult stature in any patient with Turner sy...

A new logistic model for bacterial growth was developed in this study. The model, which is based on the logistic model, contains an additional term for expression of the very low rate of growth during a lag phase, in its differential equation. The model successfully described sigmoidal growth curves of Escherichia coli at various initial cell concentrations and constant temperatures. The model ...
