To test the validity of using international standards as references for the assessment of nutritional status, investigations have been carried out on pre-school aged children selected from three distinct ecological environments in Papua New Guinea. Field work included anthropometric measurements (weight, height, triceps skin-fold, mid-upper-arm circumference, mid-upper-arm muscle circumference), together with pathological and clinical assessments (intestinal helminths, diarrhoea, splenomegaly, PEM signs). The findings indicate that any deviation below standard weight, height, and arm circumference is associated with greater prevalence of disease. International standards are therefore appropriate for preschool aged children in Papua New Guinea and by inference in other developing countries.
SynopsisThree important characteristics of loose wool bulks; compression, felting, and handle score are shown to be dependent upon the decrimping properties of the fibers. The relationship between decrimping energy and compressional load is very strong and it is suggested that rapid measurement of compressional properties may be of use in commerce and manufacture.
Measurement of Decrimping ParametersSingle fibers (8) were drawn a t random from each sample; and after preliminary soaking in distilled water for 20 hr at 20°C, the fibers were Box 793, P.O.,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
