An Erratum has been published for this article in Prenatal Diagnosis 22(11) 2002: 1056. We report a case of maternal isodisomy 10 combined with mosaic partial trisomy 10 (p12.31-q11.1). Chromosome examinations from a CVS sample showed a karyotype 47,XY,+mar/46,XY. The additional marker chromosome which was present in 6/25 interphase nuclei was shown by fluorescence in situ hybridization (FISH) to have been derived from a pericentromeric segment of chromosome 10. DNA analysis was performed from umbilical cord blood from the fetus after termination of the pregnancy at 18 weeks. The results showed that the two structurally normal chromosomes 10 were both of maternal origin, whereas the marker chromosome derived from the father. Autopsy of the fetus revealed hypoplasia of heart, liver, kidneys and suprarenal glands, but, apart from a right bifid ureter, no structural organ abnormalities. This fetus represents the second reported instance of a maternal uniparental disomy (UPD) 10. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

This work presents the results of a study on accelerated carbonation of incinerator air pollution control residues, with a particular focus on the modifications in the leaching behaviour of the ash. Aqueous carbonation experiments were carried out using 100% CO2 at different temperatures, pressures and liquid-to-solid ratios, in order to assess their influence on process kinetics, CO2 uptake and the leaching behaviour of major and trace elements. The ash showed a particularly high reactivity towards CO2, owing to the abundance of calcium hydroxides phases, with a maximum CO2 uptake of ~250 g/kg. The main effects of carbonation on trace metal leaching involved a significant decrease in mobility for Pb, Zn and Cu at high pH values, a slight change or mobilization for Cr and Sb, and no major effects on the release of As and soluble salts. Geochemical modelling of leachates indicated solubility control by different minerals after carbonation. In particular, in the stability pH range of carbonates, solubility control by a number of metal carbonates was clearly suggested by modelling results. These findings indicate that accelerated carbonation of incinerator ashes has the potential to convert trace contaminants into sparingly soluble carbonate forms, with an overall positive effect on their leaching behaviour. 相似文献

Taxonomic composition, biomass, primary production and growth rates of the phytoplankton community were studied in two stations in the NW Adriatic Sea on a seasonal basis, in areas characterized by differing hydrological and trophic conditions. The main differences between the two stations were quantitative rather than qualitative, most phytoplankton species being common to both stations. The effects of differing nutrient concentrations and plume spreading were evident. Biomass and primary production rates were significantly higher in the coastal station (S1), and the phytoplankton distribution in the water column was markedly stratified in S1 and more even in the offshore station (S3). However, chlorophyll a specific production, potential growth rate and production efficiencies were very similar in both stations, even when phosphorus concentrations were limiting. A discrepancy between potential and actual growth rate was observed: as a feature common to both stations, comparisons between potential and actual growth rates revealed that little carbon produced by phytoplankton accumulated as algal biomass; therefore, very high loss rates were estimated. 相似文献

ABSTRACTThis paper revisits the development of Toronto and Brussels’ local food policies by analysing reflexivity and co-learning as important dimensions within a Hybrid Governance Approach (HGA); it approaches the interaction between four forms of governance (bottom-up, networked, state, market-led) and the tensions between them as hybrid dynamics. Within this approach, reflexivity refers to the positionality of agents, i.e. to the ways local food actors embody as well as reflect on and reconsider their principles and practices through time. Closely related to reflexivity, co-learning involves agential interactions to co-construct enabling food policy delivery systems. The HGA is mobilised to understand the ways in which reflexive capacities, as well as co-learning, take place in the two cases and how they lay the basis of particular modes of (de)institutionalisation. Learning from the two cases’ trajectories, this paper highlights: (a) the role of key governance tensions as triggers as well as breeding grounds for reflexivity and co-learning outcomes; (b) the challenges of food movement actors to surmount or valorise key tensions in order to build accountable modes of food policy delivery through time; (c) the struggles to build legitimacy and accountability in local food movements through the development of bottom-linked organisations and governance modes. 相似文献
