    The screening of more than 2,000 schoolgirls for bacteriuria using an automated fluorescence microscopy system (1985)
    Springer
    Urological research 13 (1985), S. 143-148 
    Details
    ISSN: 1434-0879
    Keywords: Bacteriuria ; Rapid detection ; Acridine Orange ; Fluorescence ; Bactoscan

    Topics: Medicine
    Notes: Summary After initial evaluation of a manual fluorescence microscopy system on a variety of urines the method was automated and subsequently tested in a population survey of urinary tract infection in schoolgirls. This automated Bactoscan system allowed a rapid analysis of urine samples and with the introduction of modifications to the staining protocol it correctly eliminated 91% of samples as being not significantly infected.

    ISSN: 1434-0879
    Keywords: Bacteriuria ; Social habits ; Incontinence ; Schoolgirls

    Topics: Medicine
    Notes: Summary The prevalence of urinary tract infection in a modern Scottish town has been ascertained in female school children aged 5–12. In 2,234 girls the initial prevalence of urinary tract infection is 3.3%. In addition to the information on urinary tract infection the social and personal history was available including data on incontinence, enuresis and current antibiotic therapy. The necessity to have a system available which allows a cheap and rapid assessment of population surveys is made.

    Temperature dependence of secondary crystallization in linear polyethylene (1969)
    New York : Wiley-Blackwell
    Journal of Polymer Science Part A-2: Polymer Physics 7 (1969), S. 659-666 
    Details
    ISSN: 0449-2978
    Keywords: Physics ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Physics
    Notes: A specimen of linear polyethylene was subjected to isothermal secondary crystallization at a series of temperatures below the primary isothermal crystallization temperature, the melting and primary crystallization stages being held constant throughout the investigation. Dilatometric measurements exhibit an S-character at low values of undercooling Tp - Ts, where Tp and Ts are, respectively, the primary and secondary crystallization temperatures; at larger undercoolings, however, an initial very rapid crystallization is followed by a very slow stage. When corrected for thermal contraction of the polymer, the net degree of secondary transformation is seen to peak at a temperature in the range 109-113°C. The S-character of the isotherms and the peaked temperature variation of degree of transformation lead to the conclusion that a large portion of the secondary crystallization consists of the nucleation and growth of the new crystallites. Johnson-Mehl-Avrami analysis leads to a model of heterogeneous nucleation within the remaining amorphous zones, followed by one-dimensional, diffusion-controlled growth.

    Description / Table of Contents: Sommaire Un système de commandes myoélectriques est celui, où le fonctionnement d'un dispositif est contrôlé par le potentiel électrique produit par la contraction volontaire d'un muscle. Ces systèmes sont surtout employés pour la commande de membres artificiels. Les premiers types de systèmes de commande était empiriques, mais de récents travaux ont produit des bases théoriques, pouvant prédire leur performance. Ceci devrait pouvoir améliorer les systèmes déjà existants, et rendre possible le développement de prothèses plus complexes.
    Abstract: Zusammenfassung Bei einem myoelektrischen Steuersystem wird der Betrieb eines Geräts durch ein elektrisches Potential gesteuert, das durch freiillige Kontraktion eines Muskels erzeugt wird. Diese Systeme wurden hauptsächlich zur Kontrolle künstlicher Glieder verwendet. Frühere Entwürfe des Steuersystems waren empirisch, jedoch wurden kürzlich einige theoretische Grundlagen erarbeitet, die ihre Leistung vorbestimmen können. Dieses wird zur Verbesserung der bestehenden Systeme führen und die Entwicklung mehr komplexer Prothesen wahrscheinlicher machen.
    Notes: Abstract A myoelectric control system is one in which the operation of a device is controlled by the electric potential produced by voluntary contraction of a muscle. These systems have been used mainly for the control of artificial limbs. Early design of the control systems was empirical, but recent work has provided some theoretical basis for predicting their performance. This should lead to improvements in existing systems and make feasible the development of more complex prostheses.

    Notes: Abstract Progress in the development of a system to provide sensory feedback of the pinch force of an artificial hand is described. Design criteria relating to electrocutaneous stimulation and compatibility with myoelectric control are discussed. Details of a practical system, presently in use by two amputees prior to full-scale clinical evaluation, are presented.

    Optimization of capillary parameters for gas chromatography (1984)
    Weinheim : Wiley-Blackwell
    Journal of High Resolution Chromatography 7 (1984), S. 382-388 
    Details
    ISSN: 0935-6304
    Keywords: Gas chromatography ; Capillary columns ; HETP equation ; Optimum column parameters ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: An HETP equation for the capillary column is developed that takes into account the dependence of gaseous diffusion on pressure, the compressibility of the mobile phase, together with the unique relationship between mobile phase velocity, and the resistance to mass transfer in the stationary phase. The equation is used to develop a procedure for column optimization and expressions are derived that allow the optimum column radius and optimum column length to be calculated for a given fixed inlet pressure. It is shown that fast, simple separations are optimally achieved using relatively short small diameter columns. Conversely, optimum performance for the separation of complex mixtures requiring higher efficiencies requires the use of long columns with relatively large diameters.
