    Notizen: Abstract An outdoor study was undertaken using polyethylene containers to assess the suitability of different organic residues, soybean straw (Glycine max L. Merril.), wheat straw (Triticum aestivum L.), maize stover (Zea mays L.), chickpea straw (citer arietinum L.) and city garbage, as food for the tropical epigeic earthwormPerionyx excavatus, and to assess the influence of this earthworm on the decomposition of these materials. Maize stover was found to be the most suitable of the food materials used. Population growth ofP. excavatus was enhanced by addition of these organic materials in the temperature range 24°-30°C, while the population was adversely affected above 30°C in a vermiculture system. Addition of earthworms accelerated the breakdown of residues, which ultimately resulted in a lowering of the C:N ratio, water-soluble carbon and carbohydrates, and increased ash percentage and cation exchange capacity compared with their respective controls.

    Notizen: Abstract An outdoor study was undertaken using polyethylene containers to assess the suitability of different organic residues, soybean straw (Glycine max L. Merril.), wheat straw (Triticum aestivum L.), maize stover (Zea mays L.), chickpea straw (cicer arietinum L.) and city garbage, as food for the tropical epigeic earthworm Perionyx excavatus, and to assess the influence of this earthworm on the decomposition of these materials. Maize stover was found to be the most suitable of the food materials used.

    Intellectual outcome, speech and school performance in high risk preterm children with birth weight appropriate for gestational age (1990)
    Springer
    European journal of pediatrics 149 (1990), S. 845-850 
    Details
    ISSN: 1432-1076
    Schlagwort(e): Preterm children ; Intellectual development ; Speech ; School performance ; 5–9 years of age

    Notizen: Abstract Intellectual development, speech and school performance of preterm infants with birth weight appropriate for gestational age are reported in two separate investigations: 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 groups with respect to number of outborns, distribution of gestational age and perinatal risk factors. Intellectual outcome at 5 and 7 years of age in the majority of the preterm children was comparable to that of the term children. However, 8% of the preterm boys and 2% of the preterm girls achieved lower IQ scores than any of the term children. Between 15% and 17% of the preterm boys and 9%–12% of the preterm girls did not attend school at grade level, compared to 4% and 2% in the term group, respectively. Intellectual and neurological development and school performance were higher interrelated in the preterm than in the term children. Articulation defects, stuttering and dysgrammatism occurred more frequently in the preterm than in the term children and in boys more so than in girls.

    Neurological outcome in high risk weight appropriate for gestational age preterm children at early school age (1990)

    Notizen: 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.
