Infant length measurements.

Reliability of infant length measurement.

The reliability of length measurement was determined in 38 infants less than 1 year of age. The SD of a single length measurement was 0.28 cm at birth and 0.42 cm both at 6 weeks and at 8 months of age, comparable with the SD of a single height measurement in previously reported older children. There is no technical reason to prevent reliable measurement of young infants.

Aortic length: angiocardiographic measurements.

Statistical analysis of measurement of aortic length made on 250 angiocardiograms indicates that arteriosclerosis, hypertension and syphilitic aortitis produce elongation of the aorta. Aortic length varies widely among normal individuals but is roughly ten times the caliber of the ascending aorta. Syphilitic aortitis produces disproportionate elongation of the ascending portion of the aorta as ...

Evaluation of Curve Length Measurements

This paper compares two techniques for measuring the length of a digital curve. Both techniques (digital straight segment approximation, minimum length polygon) are known to be convergent estimators. Theoretical convergence results are cited. The main focus is on experimental evaluation: several measures are dened, applied and discussed. Test sets are digitized for consecutive resolutions. 1. T...

the effects of maternal cigarette smoking on infant anthropometric measurements

background: the association between maternal smoking and poor pregnancy outcome, which is well established in medi­cal literature, has also been corroborated by the results of this study conducted in a turkish hospital. our objective was to investi­gate the effects of cigarette smoking during pregnancy on infant head circumference, height, weight, and body mass in­dex (bmi). methods: in this re...
