Notes: Abstract Neurological development in preterm children with birth weight appropriate for gestational age is reported in two separate groups: a longitudinal study of 97 preterm children and 93 term children as a control group and a cross-sectional study of 249 preterm children. Both preterm groups were regarded as high risk with respect to number of outborns, distribution of gestational age and perinatal risk factors. Neurological outcome at 5–6 years of age in the majority of the preterm children was comparable to that of the term children. However, 15% of boys and 9% of girls in the preterm group were diagnosed as having cerebral palsy. Mild diplegia was most frequently observed; 4% of the children were severely impaired. Fourteen percent of the preterm vs 2% of the term boys and 6–9% of the preterm vs none of the term girls received motor therapy during early school age. There was a small but consistent sex difference in neurological outcome in favour of the term and preterm girls. Effects of drop out rate and of incompleteness of ascertainment are reported in detail.

Notes: Raw and partially delignified jute fibers were grafted with acrylonitrile and methyl meth-acrylate monomers, using the redox system of initiation with ceric ammonium sulfate. Grafting was also carried out in a mixed monomer system with acrylonitrile and methyl methacrylate monomers in different proportions. The optimum grafting condition depends on the duration of grafting treatment and proportion of grafting monomers. The monomers entered the fiber matrix with high add-on and, at still higher graft add-ons, the ultimate fibers suffered disintegration. The surfaces were increasingly covered with grafted materials and longitudinal cracks developed on the fiber surface with higher add-on. © 1993 John Wiley & Sons, Inc.
