    Notes: To examine the relationship between blood pressure (BP) and pulse transit time (PTT) as measured by the time between the ECG R-wave and an associated peripheral pulse, BP was recorded via a radial artery catheter in 3 hvpertensive subjects who underwent a variety of conditions to alter BP. Overall. 70% of the data was usable. Absolute levels of systolic blood pressure (SBP) but not diastolic blood pressure (DBP) were found to correlate appreciably with PTT. There were significant associations between PTT and both SBP and mean BP but not DBP for direction of BP change. With large SBP changes (〉 4 mmHg) an increase in the strength of association occurred in 14 of the 21 conditions across subjects. Overall, PTT did not accurately predict actual BP. PTT and SBP covaried more appreciably in these hypertensives than has been reported for normotensives.

    Notes: [Auszug] Rate of oxygen consumption increased curvilinearly with speed for walking and trotting (Fig. 1). We were unable to obtain sufficiently high galloping speeds to evaluate whether rate of oxygen consumption also increased curvilinearly during a gallop. Transitions between gaits normally occurred at ...

    Notes: Summary Glutathione-insulin transhydrogenase catalyzes the inactivation of insulin by splitting the hormone into A and B chains. We have localized this enzyme immunocytochemically by light microscopy in the pancreas, kidney and liver of both lean and obese (ob/ob) mice and similarly in normal and streptozotocin-diabetic rats. Localization was achieved by an antibody to glutathione-insulin transhydrogenase using a peroxidase-antiperoxidase technique. In comparison with tissues from control animals, positive immunostaining for glutathione-insulin transhydrogenase was increased in the obese mouse but reduced in the diabetic rat. Different tissues showed considerable variation in the amount of glutathioneinsulin transhydrogenase which could be detected. In the pancreatic islets there was little or no evidence for the presence of the enzyme in peripheral cells. In the kidney, immunocytochemical staining was found only in the proximal tubules. In the liver there was a generalised distribution of the enzyme, but the greatest concentration was in the periportal region. These observations parallel the biochemical data relating to glutathione-insulin transhydrogenase, indicating that different amounts of insulin degrading activity exist in different regions of tissues.

    A simple tool for speckle-shearing interferometry (1981)
    Springer
    Experimental mechanics 21 (1981), S. 436-440

    Notes: Abstract A common glass plate has been shown to be an adaptable and effective tool for use in speckle-shearing interferometry. Analyses of both the imaging system and the optical-filtering arrangement have been developed. Experiments were performed successfully. The results of these experiments have shown that visible speckle correlation fringes related to the derivatives of surface displacement are obtained when a common glass plate is used as a shearing component.

    Modelling flow over a backward-facing step using the F.E.M. and the two-equation model of turbulence (1981)

    Notes: Flow over a downstream-facing step is predicted using the F.E.M. A two-equation model of turbulence is employed where the transport of turbulence kinetic energy and dissipation rate are depicted using transport-type equations, i.e. the two-equation model of turbulence. The results obtained are compared with other models and experimental results. Generally, the model was found to be under-predictive with regard to the reattachment length when previous empirical data was used in the transport equations.
