CARBON AND COKE REACTIVITY IN ZINC-LEAD BLAST FURNACE PRACTICE

Previous research on the oxidation of coke in air, O2 and CO2 has been reviewed, especially with regard to kinetic studies and Zn/Pb blast furnace practice. Coke "reactivity" has been discussed and correlated with surface area changes on carbon burn-off (in air and CO2 at various temperatures) for Nauitgarw and two other metallurgical cokes. Other carbons (charcoals and graphite) and a-brovnr. coal char~ have been examined by gas sorption, X ray diffraction and thermal analysis in an attempt to relate reactivity, as determined by rate of reaction in CO2 at 1000°C, with other solid state properties. Reactivity studies on coal chars have been reviewed also. The inhibition of the Boudouard reaction, by modification of the carbon surface, has been reviewed, especially by the action of'B203. Cokes and coal char have been subject to B2O3 solution treatment and the mode of action of the inhibitor investigated by isothermal and dynamic thermal analysis and estimation of surface area by gravimetric gas sorption. The action of B2O3 at both low and high degree of carbon burn o f f has been studied. The mineral matter of coke (which forms about 10% by weight of the material) and the coal char (which forms about 2%) has been examined by X ray diffraction , optical and electron microscopy and thermal and chemical analysis. Its affect upon the kinetics of oxidation has been investigated. Results have been discussed in relation to the industrial usage of coke in the Zn/Pb blast furnace.Department of Environmental Sciences; Imperial Smelting Processes Ltd., Avonmout

CATALISE: A multinational and multidisciplinary Delphi consensus study. Identifying language impairments in children

© 2016 Bishop et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Delayed or impaired language development is a common developmental concern, yet there is little agreement about the criteria used to identify and classify language impairments in children. Children\u27s language difficulties are at the interface between education, medicine and the allied professions, who may all adopt different approaches to conceptualising them. Our goal in this study was to use an online Delphi technique to see whether it was possible to achieve consensus among professionals on appropriate criteria for identifying children who might benefit from specialist services. We recruited a panel of 59 experts representing ten disciplines (including education, psychology, speech-language therapy/pathology, paediatrics and child psychiatry) from English-speaking countries (Australia, Canada, Ireland, New Zealand, United Kingdom and USA). The starting point for round 1 was a set of 46 statements based on articles and commentaries in a special issue of a journal focusing on this topic. Panel members rated each statement for both relevance and validity on a sevenpoint scale, and added free text comments. These responses were synthesised by the first two authors, who then removed, combined or modified items with a view to improving consensus. The resulting set of statements was returned to the panel for a second evaluation (round 2). Consensus (percentage reporting \u27agree\u27 or \u27strongly agree\u27) was at least 80 percent for 24 of 27 round 2 statements, though many respondents qualified their response with written comments. These were again synthesised by the first two authors. The resulting consensus statement is reported here, with additional summary of relevant evidence, and a concluding commentary on residual disagreements and gaps in the evidence base
