    Pharmacokinetics of pirprofen in young volunteers and elderly patients (1985)
    Springer
    European journal of clinical pharmacology 29 (1985), S. 73-77 
    Details
    ISSN: 1432-1041
    Keywords: pirprofen ; arthritic disease ; pharmacokinetics ; elderly patients
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Plasma concentrations of pirprofen were measured in 11 elderly arthritic patients and 6 healthy young volunteers at the beginning and end of 8 days treatment with 400 mg doses twice daily. The mean ages of the two groups were 74.5 and 21.8 years, respectively. There were no statistically significant differences in peak concentrations, times to peak, areas under the curve or terminal elimination half-lives between the groups after single dosing. Repeated dosing increased plasma drug concentrations in both groups but the extent was as predicted from the single dose data. Again there were no statistically significant differences between the groups, although pre-dosing plasma concentrations were higher in the elderly compared with the young individuals. The results of this relatively small study suggest that advancing age and arthritic disease appear to have little influence on the pharmacokinetics of pirprofen and no modification in the dosage recommendation in elderly patients without overt renal or hepatic impairment is indicated.

    Determination of the Bimolecular Rate Constant for the Reaction Between Organophosphorous Inhibitors and Esterases in the Presence of Substrate (1963)

    Notes: [Auszug] THE bimolecular rate constant (ki) for the reaction between an organophosphorous inhibitor (I) and an esterase (E) is usually determined by Aldridge's method1 or by some variation of it. Essentially the method consists of incubating a solution containing (E) and an excess of (I) for a measured time ...

    Calibration of a four-hole pyramid probe and area traverse measurements in a short-duration transonic turbine cascade tunnel (1996)
    Springer
    Experiments in fluids 21 (1996), S. 302-311 
    Details
    ISSN: 1432-1114

    Notes: Abstract A four-hole pyramid probe has been calibrated for use in a short-duration transonic turbine cascade tunnel. The probe is used to create area traverse maps of total and static pressure, and pitch and yaw angles of the flow downstream of a transonic annular cascade. This data is unusual in that it was acquired in a short-duration (5 s of run time) annular cascade blowdown tunnel. A four-hole pyramid probe was used which has a 2.5 mm section head, and has the side faces inclined at 60° to the flow to improve transonic performance. The probe was calibrated in an ejector driven, perforated wall transonic tunnel over the Mach number range 0.5–1.2, with pitch angles from -20° to + 20° and yaw angles from-23° to +23°. A computer driven automatic traversing mechanism and data collection system was used to acquire a large probe calibration matrix (∼ 10,000 readings) of non dimensional pitch, yaw, Mach number, and total pressure calibration coefficients. A novel method was used to transform the probe calibration matrix of the raw coefficients into a probe application matrix of the physical flow variables (pitch, yaw, Mach number etc.). The probe application matrix is then used as a fast look-up table to process probe results. With negligible loss of accuracy, this method is faster by two orders of magnitude than the alternative of global interpolation on the raw probe calibration matrix. The blowdown tunnel (mean nozzle guide vane blade ring diameter 1.1 m) creates engine representative Reynolds numbers, transonic Mach numbers and high levels (≈ 13%) of inlet turbulence intensity. Contours of experimental measurements at three different engine relevant conditions and two axial positions have been obtained. An analysis of the data is presented which includes a necessary correction for the finite velocity of the probe. Such a correction is non trivial for the case of fast moving probes in compressible flow.

    The impact of tick parasites on the behaviour of the lizard Tiliqua rugosa (2000)
    Springer
    Oecologia 122 (2000), S. 574-581

    Keywords: Key words Lizards ; Ticks ; Home range ; Sprint speed ; Parasite-host interaction
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract  Populations of the Australian sleepy lizard, Tiliqua rugosa, near Mt. Mary, South Australia carry natural infestations of two tick species Aponomma hydrosauri and Amblyomma limbatum. In field experiments at two sites, 18 km apart, lizards with experimentally increased tick loads had smaller home ranges, moved shorter distances in a day, and were found basking more but moving less often than lizards from which ticks were experimentally removed. The results were consistent for adult lizards in two years, and for sub-adults in a third year. Laboratory trials showed that juvenile lizards that had tick infestations had lower sprint speeds than uninfested siblings, and that adults with tick infestations had less endurance than those that were uninfested. The results contrast with those of a previous survey that showed that lizards with high tick loads had greater body size and remained longer at a site, but indicate that there may be a balance, for lizards, between the fitness advantages in occupying habitats with high-quality resources, and the costs from parasites that also prefer those habitats.

    Use of mice for initial approximation of reentry intervals into pesticide-treated fields (1974)
    Springer
    Archives of environmental contamination and toxicology 2 (1974), S. 233-242

    ISSN: 1432-0703
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering , Medicine
    Notes: Abstract The possibility of using laboratory mice to obtain information relative to establishment of reentry intervals for pesticide-treated fields was investigated. Pre- and postexposure blood cholinesterase levels of mice exposed for 10 hours to insecticide-treated (field applications) tobacco, cotton, or apple leaves were determined at 24 hour intervals. Differences were found between insecticides with respect to both initial inhibition and residuality as well as different types of foliage, rates of application, and formulation.
