    Enlarging skull fractures in children (1995)
    Springer
    Child's nervous system 11 (1995), S. 265-268

    Notes: Abstract Large skull fractures are conventionally followed radiographically until healing occurs. Fractures which enlarge or remain unhealed are commonly termed “leptomeningeal cysts” or “growing skull fractures”. This study of ten children with this injury and a review of the literature shows that a true leptomeningeal cyst is seldom present and that skull fractures do not “grow”. Moreover, careful history-taking and physical examination will correctly identify all enlarging or unhealed skull fractures of childhood without the need for plain radiographs or computed tomography of the skull.

    Variation in PED response at a gold microelectrode as a function of waveform parameters when applied to alditols and carbohydrates separated by capillary electrophoresis (1995)
    Weinheim : Wiley-Blackwell
    Electroanalysis 7 (1995), S. 1015-1019 
    Details
    ISSN: 1040-0397

    Notes: Results are presented from a systematic study of the noise (N) and peak-to-noise ratio (P/N) obtained for pulsed electrochemical detection (PED) at a gold micro-wire electrode applied to a mixture of alditols and monosaccharides separated by capillary electrophoresis (CE). The electrode potentials and time periods for oxidative cleaning and reductive reactivation of the electrode were held constant in the PED waveform at minimum allowable values and the time period for digital integration of electrode current (tint) was varied from 50 to 800 ms by 50-ms intervals. The value of N was virtually independent of tint and P/N increased approximately as a linear function of tint in the range 50-200 ms corresponding to waveform frequencies in the range 4.5-2.7 Hz. A detection limit of 9 fmol glucose was determined for a 4-nL injection using tint = 200 ms.

    Fast-pulsed electrochemical detection at noble metal electrodes: The frequency-dependent response at gold electrodes for chromatographically separated carbohydrates (1994)
    Weinheim : Wiley-Blackwell
    Electroanalysis 6 (1994), S. 269-273 
    Details
    ISSN: 1040-0397
    Keywords: Pulsed electrochemical detection ; Carbohydrates ; Liquid chromatography ; Chemistry ; Polymer and Materials Science

    Topics: Chemistry and Pharmacology
    Notes: Waveforms used in pulsed electrochemical detection (PED) have frequencies of ca. 1 Hz when optimized to give a maximum signal-to-noise ratio (S/N) for carbohydrates. However, higher frequencies are desired for application of PED to capillary electrophoresis (CE) and microcolumn lipuid chromatography (MLC), which can produce narrow elution peaks. Minimization of the time periods for oxidative cleaning and reductive reactivation in PED waveforms generated by the Dionex pulsed Electrochemical Detector allows the increase in waveform frequency to ca. 3 Hz without change in the traditional time period of 200 ms, prescribed for integration of the anodic current. However, further increase in frequency requires a decrease in the integration period with a corresponding loss of signal strength.
