    Growth and reproduction of the vermicomposting earthwormPerionyx excavatus as influenced by food materials (1997)

    Notes: 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.

    Early fine motor and adaptive development in high-risk appropriate for gestational age preterm and healthy term children (1991)
    Springer
    European journal of pediatrics 150 (1991), S. 562-569 
    Details
    ISSN: 1432-1076
    Keywords: Fine motor and adaptive development ; Term and preterm children ; Influence of prenatal ; Perinatal and postnatal variables ; Predictive significance of fine motor and adaptive skills
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The development of fine motor and adaptive skills during the first 2 years of life is reported in 97 highrisk preterm children and 94 healthy term children. Most stages of fine motor and adaptive development were found to occur at slightly later ages among preterm children. Neurological development was significantly correlated with fine motor and adaptive development in preterm children only. No significant influence of prenatal, perinatal and postnatal variables on fine motor and adaptive development was noted. No significant sex differences were observed in both the term and preterm group. The strongest predictors of later intellectual functioning were fine motor performance at 9 months and fine motor and adaptive skills at 18 to 24 months.

    Bioconversion of cellulose into ethanol by Clostridium thermocellum - product inhibition (1983)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Direct anaerobic bioconversion of cellulosic substances into ethanol by Clostridium thermocellum ATCC 27405 has been carried out at 60°C and pH 7.0 (initial for 100 L) under continuous sparging of oxygen free nitrogen in a culture vessel. Raw bagasse, mild alkali-treated bagasse, and solka floc were used as substrates. The extent of conversion of raw bagasse (cellulose, 50%; hemicellulose, 25%; lignin, 19%) was observed as 52% (w/w) and 79% (w/w) in the case of mild alkali and steam-treated bagasse (cellulose, 72%; hemicellulose, 11%; lignin, 12%), respectively. Use of bagasse concentration above 10 g/L showed a decreased rate in ethanol production. An inoculum age between 28-30 h and cell mass content of 0.027-0.036 g/L (dry basis) were used. The results obtained with raw and pretreated bagasse have been compared with those of highly pure Solka Floc (hemicellulose, 10%). Studies on the product inhibition indicated a linear fall of the percent of survivors with time. An Arrhenius type correlation between the cell decay rate constant and the product concentration was predicted. Even at low levels, the inhibitory effects of products on cell viability, the specific growth rate, and extracellular cellulase enzyme were observed.
