    Notes:
    Abstract This paper analyses continuous alloy plating of steel strip with the use of a rate model that accounts for migration and homogeneous equilibria in the mass-transport boundary layer adjacent to the cathode. The model predicts the effect of bath composition, temperature, electrolyte velocity, and current density on the alloy composition and current density distribution within the cell. The effect of a slight taper of the interelectrode gap was also considered. The results were used to evaluate which of several currently used electrogalvanizing cells are most likely to succeed in producing coats of uniform zinc-nickel alloy composition. It is demonstrated that mass-transfer of the zinc is a critical factor under typical industrial conditions and that electrolyte injection counter to the strip movement is important for application of an electrodeposit uniform in composition.

    Notes:
    Summary Xylose metabolism by Candida shehatae in continuous culture was examined under both fully-aerobic and semi-aerobic conditions. Growth did not occur in the absence of respiration. Under fully-aerobic conditions, the cell yield was constant at 0.51 g/g and the specific respiration rate Q o 2 was linearly related to the specific growth rate μ with a slope of 15 mmol g-1 and an intercept of 1.2 mmol g-1 h-1. Under semi-aerobic conditions, Q O 2 was proportional to μ with a slope consistent with a cell yield from oxygen Y O 2 of 35±7 g mol-1. The specific xylose uptake rate was a constant independent of μ and equal to the maximum rate of xylose transport. Ethanol production was observed under semi-aerobic conditions only, and the specific fermentation rate was inversely related to μ.

    Notes:
    Summary It is now well established that in almost all cases of chronic non-specific lung disease, with significant parenchymal damage, administration of a bronchodilator by any route causes a fall in the arterial oxygen tension. This has been ascribed to increased perfusion of poorly ventilated areas in the diseased lung, i. e. increase in venous admixture. However, we previously noted that intravenous administration of the spasmolytic drug, papaverine, elevated arterial oxygen tension in these patients. Accordingly, papaverine was added, in various concentrations, to isoprenaline inhalations given to nine such patients; the mean fall in Pot was 1.3 mmHg., (five showing no fall or an increase), which compares favourably with a decrease of 8.4 mmHg. in a similar group having isoprenaline alone.

    Notes:
    The metabolism of deutrated cortisol (9,12,12,-2H)cortisol, (2H3-F) was compared to that of radioactive cortisol (3H2-F) and natural cortisol, when these three compounds were administered simultaneously to an adrenalectomized piglet. The relative isotope dilution of tritium was determined from the specific activities of the main urinary neutral cortisol metabolites, tetrahydrocortisone (THE) and tetrahydrocortisol (THF), normalized to that of the cortisol mixture administered. To obtain a comparison of the isotope dilution of deuterium in the metabolites THE and THF to that in the cortisol mixture, the three steroids were converted to the common oxidation product 11-oxo-aetiocholanolone, and deivatized to the methoxime-tert-butyl-dimethylsilyl ether. The relative 2H-isotope dilution then was measured by gas chromatography/mass spectrometry. It was found that the specific activity of THE in the cumulative urine collections was similar to that of the cortisol mixture administered; the two-day value was, however, less. The specific activity of THF was slightly but significantly smaller than 1 (∼0.9) at all times. The relative 2H-isotope dilution in THE was slightly but significantly larger than one (∼1.1) at all times, whereas that in the THF was larger than 1.0 at 9 and 32 h or equal to 1.0 at 20 and 47 h of urine collection. When comparing the metabolism of the two tracer cortisol species the quotient of the 3H- and the 2H-isotope dilutions in THE and THF was smaller than 1.0. It can be concluded that (2H3)cortisol may be used for the determination of the cortisol production rate.

    Notes:
    An isotope dilution mass spectrometric method to determine the urinary cortisol production rate (CPR) in babies and children is described. The method uses stable isotopically labelled (1,2,3,4-13C)cortisol. The tracer is intravenously administered to the patient and urine is collected for the following three days. Following extraction, enzymic hydrolysis, purification and isolation by high-performance liquid chromatography (HPLC) the urinary cortisol metabolites tetrahydrocortisone, tetrahydrocortisol, α- and β-cortolone are separately oxidized to the common product, 11-oxo-aetiocholanolone. The methyl oxime tert-butyldimethylsilyl ether derivative (MO TBDMS) was analysed by gas chromatography mass spectrometry. Quantification of the isotope enrichment was carried out by selected ion monitoring of the base fragment ion at m/z 344[M-103]+ for unlabelled, and at m/z 348 for labelled 11-oxo-aetiocholanolone. HPLC isolation of the metabolites together with the oxidation step allowed very small isotope enrichments, sometimes down to 0.1% (1:1000), to be reliably measured against a linear calibration graph containing 0 to 1% (13C4) enrichments. The standards for the calibration graph were synthesized from mixtures of labelled (13C4) cortisol and natural cortisol, and the calibration graph was prepared each time samples were measured. The long term instrumental precision of the isotope dilution analyses was 0.91% for a derivatized sample containing a (13C4) enrichment of 0.5% (measured on six different days over seven months). The coefficient of variation of the complete procedure for the four cortisol metabolites was between 1.17 and 2.14%. The clinical applicability of the method is demonstrated by presenting the results of a CPR determination in a patient.
