    Retention of nutrients by the different wastes produced by the kaolin mining industry in Cornwall (1981)
    Springer
    Plant and soil 59 (1981), S. 153-158 
    Details
    ISSN: 1573-5036
    Keywords: Amendments ; Kaolin mining wastes ; Leaching ; Mica ; Nutrient loss ; Overburden ; Sand ; Top-soil
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary The chemical composition and leaching loss of applied fertilizers were measured from four waste materials derived from china clay extraction. Two waste materials, overburden and mica, had a higher nitrogen and calcium concentration, and were more efficient than sand wastes for the retention of these elements when applied as fertilizers. The possibility of using overburden and mica wastes as amendments for sand waste reclamation is briefly discussed.

    Analysis of gaseous exchange in open-circuit indirect calorimetry (1984)
    Springer
    Medical & biological engineering & computing 22 (1984), S. 333-338 
    Details
    ISSN: 1741-0444

    Notes: Abstract A method is described for determining rapid changes in gaseous exchange between a subject and the environment, while living in a whole body opencircuit calorimeter. The formulae which must be applied to standard estimates of oxygen consumption are derived the computation of rates of change of gas concentration is discussed the sensitivity of estimated heat production to errors in gas concentration is determined and heat production shown to be largely independent of CO2 measurements; and examples of veritication of the method for known rates of gas injection, and of its use with human subjects, are given. The method is of particular value in assessing the rapid changes in metabolic rate which occur as a result of changes in activity, nutritional state, environmental temperature and the administration of drugs. Such changes are monitored in an unrestrained subject living in a whole-body calorimeter rather than in a subject living with the restrictions imposed by a face-mask or ventilated hood.

    First Fourier-transform ion cyclotron resonance signals of very highly charged atomic ionsContribution from the 2nd European FTMS Workshop, Antwerp, Belgium, September 1993. (1994)
    New York, NY : Wiley-Blackwell
    Rapid Communications in Mass Spectrometry 8 (1994), S. 141-143 
    Details
    ISSN: 0951-4198
    Keywords: Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Physics
    Notes: We report on the first application of Fourier-transform ion cyclotron resonance mass spectrometry to the very highly charged ions produced in the high-energy electron beam ion trap (SuperEBIT) at the Lawrence Livermore National Laboratory. Initial results are described, and spectra are presented from ions as highly charged as Cs53+.
