    Fiberoptic endoscopic examination of swallowing safety: A new procedure (1988)
    Springer
    Dysphagia 2 (1988), S. 216-219

    ISSN: 1432-0460

    Notes: Abstract A new procedure for assessing the pharyngeal stage of swallowing in patients with dysphagia is described. Called the fiberoptic endoscopic examination of swallowing safety (FEESS), it is being used to detect aspiration and to determine the safety of oral feeding in patients for whom the traditional videofluoroscopic evaluation may be difficult or impossible to perform. Patients for whom the FEESS procedure is indicated are identified and information obtainable via endoscopy is outlined.

    Purification of silicone oils for fluid experiments (1995)
    Springer
    Experiments in fluids 19 (1995), S. 359-361

    Notes: Abstract Commercially produced silicone oils (polydimethylsiloxanes or PDMS) that are used in many fluid experiments typically contain a mixture of linear polymers with a distribution of molecular weights. This multicomponent constitution can cause undesirable effects in some experiments; we show one such effect in surface-tension-driven Bénard convection. We describe a simple distillation protocol for obtaining low viscosity single-component silicone oils from commercially available mixtures. For polymers with molecular weights ∼ 1000, our method yields purities of better than 95 %.

    Longitudinal effects of pregnancy on the pharmacokinetics of theophylline (1987)
    Springer
    European journal of clinical pharmacology 32 (1987), S. 289-295 
    Details
    ISSN: 1432-1041
    Keywords: theophylline ; pregnancy ; pharmacokinetics ; lactation ; methylxanthines ; metabolism

    Notes: Summary The effects of pregnancy on the disposition of theophylline were assessed in 10 patients throughout pregnancy and post-partum. The clearance relative to total theophylline concentrations was only slightly affected during the first two trimesters (2.61±0.63 l/h and 2.85±1.05 l/h), while a statistically significant reduction was evident late in pregnancy (2.05±0.49 l/h). Post-partum clearance values (2.16±2.81 l/h) suggest an ongoing suppression relative to pre-pregnancy levels. A similar pattern was evident with clearance values based on free theophylline plasma concentrations (p=0.12). Absolute volume of distribution increased in concert with gestation, suggesting that theophylline partitions into the enlarged tissue spaces. In addition, theophylline binding to plasma proteins decreased, albeit insignificantly, during the second (fraction bound=29%) and third (32%) trimesters compared to post-partum values (41%). Increases in half-life during the third trimester (13.00±2.31 h vs 9.53±3.53 h post-partum) were highly significant. This change reflects the net effect of reduced clearance and increased distribution. Breast feeding had no effect on the disposition of theophylline, although the transfer of this compound into breast milk was confirmed.

    Investigation of the Strain Hardening and Bauschinger Effect of Low and High Strength Steel Application in Drawbead-Tester by Experiment and Numerical Simulation (2008)
    s.l. ; Stafa-Zurich, Switzerland
    Advanced materials research Vol. 55-57 (Aug. 2008), p. 761-764 
    Details
    ISSN: 1662-8985

    Notes: The research is aimed to investigate Bauschinger effect and strain hardening by the application of drawbead-tester. Generally, the drawbead is used to control the material flow into the die cavity in sheet metal forming process. When the material is flowing into the drawbead, it may cause the development of strain hardening and/or Bauschinger effect. This work consists of two main equipment particularly developed for the experiments. They are drawbead-tester and three-point bending device. The drawbead-tester provides the possibility to integrate the optical in-process strain analysis system. Whereas the sheet metal was being formed in the drawbead, the local strain of the sheet metal was evaluated. At the same time, the drawbead restraining and holding forces were measured. The three point bending device and numerical simulation method are used to investigate the Bauschinger effect. In the experiment, the cyclic bending forces were measured and compared with the result obtained by numerical simulation

    Thixotropievolumen und Sedimentvolumen bei Kaolinen und Tonen (1967)

    ISSN: 1435-1536

    Notes: Zusammenfassung Über 60 Kaoline und Tone wurden auf ihr Thixotropievolumen und ihr Sedimentvolumen untersucht. Das Thixotropievolumen der Tone lag in der gleichen Größe wie das Thixotropievolumen der Kaoline. Dagegen war das Sedimentvolumen einiger Kaoline erheblich größer als die höchsten Werte bei den Tonen. Tone haben erhebliche Gehalte an Plättchen mit sehr geringem Durchmesser. Diese Plättchen fallen in die Lücken des Kartenhausgerüstes aus den großen Plättchen und erniedrigen daher das Sedimentvolumen bei gleichem Gewicht an Ton. Bei Kaolinen ist die Größe des Thixotropievolumens und des Sedimentvolumens um so höher, je geringer die Dicke der Kristallplättchen ist oder je größer die Oberfläche der Kristalle ist. Ein Gehalt an Illit oder an Montmorillonit neben dem kaolinitischen Tonmineral hat bei Kaolinen und Tonen keinen deutlichen Einfluß auf Thixotropie- und Sedimentvolumen, wenn die austauschfähigen Kationen Calcium- oder Magnesiumionen sind. Austauschfähige Natriumionen geben einem Kaolinit ein kleines Thixotropie- und Sedimentvolumen, während austauschfähige Calciumionen und noch ausgeprägter H3O+-Ionen das Thixotropie- und Sedimentvolumen erhöhen. Dies läßt sich gut aus dem umgekehrten Verhalten von Montmorillonit verstehen. Natriumionen lockern den Zusammenhalt der Kristallplättchen des Kaolinits oder der Silikatschichten des Montmorillonits.
