    Notes: Abstract The physical consequences emerging from a theory stated byKraichnan are considered with regard to isotropic hydromagnetic turbulence. This theory involves the direct-interaction approximation retaining the phase correlation within each triad of Fourier amplitudes. These interactions are suggested to be very important in hydromagnetic turbulence. Hydrodynamic as well as magnetic impulse-response function and time-correlation are unequivocally the same. This result suggests the existence of a universal equilibrium range. Within the inertial range the total energy spectrumE g (k)=E(k)+E m (k) obeys the same law as in hydrodynamic turbulenceE(k). The valueE m (k)≈E(k) corresponds roughly to maximum energy flux through this range. The magnetic energy flux decreases rapidly for eddies with larger wave-numbers within the range of ohmic ≫ viscous dissipation.

    Notes: Abstract Force-free magnetic fields are defined by the equation rot $$\mathfrak{H} = \alpha \mathfrak{H}$$ . Making use of a moving Frenet coordinate system $$(\mathfrak{t} = tangential, \mathfrak{n} = normal, \mathfrak{b} = binormal unit vector)$$ we find the following general features of these fields: 1. grad $$\left| \mathfrak{H} \right|$$ is always parallel to the osculating plane of the $$\mathfrak{H}$$ -lines. 2. If the lines of force are rectilinear within a finite region of space, the component of grad $$\left| \mathfrak{H} \right|$$ along $$\left| \mathfrak{H} \right|$$ must be zero for a force-free field with rot . 3. The factor of proportionality $$\alpha = \alpha (\mathfrak{r})$$ and $$\mathfrak{H}$$ can be calculated by means of two equations involving only the direction of $$\left| \mathfrak{H} \right|$$ . For several models of force-free fields the effect of symmetry assumptions on $$\alpha = \alpha (\mathfrak{r})$$ is discussed using special coordinate systems. In the appendix it is pointed out that a particle drift arises in magnetic fields with .

    Induction of drug metabolism in man after rifampicin treatment measured by increased hexobarbital and tolbutamide clearance (1975)
    Springer
    European journal of clinical pharmacology 9 (1975), S. 219-227 
    Details
    ISSN: 1432-1041
    Keywords: Rifampicin ; induction of drug metabolism ; hexobarbital kinetics ; tolbutamide kinetics ; plasma concentrations ; man
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Five healthy volunteers took 1.2 g rifampicin daily for 8 days, and before and afterwards each received hexobarbital (7.32 mg/kg) and tolbutamide (20 mg/kg) by i.v. infusion on two consecutive days. The plasma concentrations of the two drugs were determined during and after infusion. The average elimination half-life of hexobarbital had decreased from 325 to 122 min and of tolbutamide from 418 to 183 min following rifampicin treatment. It was calculated that the metabolic clearance of hexobarbital had increased about three-fold and that of tolbutamide more than two-fold. Significant changes in the distribution kinetics of the two drugs were not observed. The results suggest that rifampicin is capable of inducing drug metabolism in man, which leads to an increased rate of elimination of drugs that undergo biotransformation in the liver.

    Stimulation of drug metabolism by rifampicin in patients with cirrhosis or cholestasis measured by increased hexobarbital and tolbutamide clearance (1977)
    Springer
    European journal of clinical pharmacology 11 (1977), S. 287-293

    ISSN: 1432-1041
    Keywords: Rifampicin ; induction of drug metabolism ; cirrhosis ; cholestasis ; hexobarbital kinetics ; tolbutamide kinetics ; plasma concentrations

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Eleven patients with hepatic cirrhosis or cholestasis were treated with rifampicin for 7 to 132 days. Ten patients received hexobarbital (7.32 mg/kg) and five received tolbutamide (20 mg/kg) by i.v. infusion prior to and after rifampicin treatment; plasma concentrations of the two test compounds were determined during and after infusion. The average elimination half-life of hexobarbital had decreased from 624 to 262 min and that of tolbutamide from 292 to 160 min following rifampicin treatment. It was calculated that the metabolic clearance of hexobarbital had increased more than two-fold and that of tolbutamide almost two-fold. The results suggest that rifampicin is able to stimulate hepatic drug metabolism in patients with liver disease. It was apparent in general that the induction did not lead to improvement of hepatocellular function during disease as judged by laboratory findings.

    Pharmacokinetics of hexobarbital in man after intravenous infusion (1975)
    Springer
    Journal of pharmacokinetics and pharmacodynamics 3 (1975), S. 1-11 
    Details
    ISSN: 1573-8744
    Keywords: hexobarbital pharmacokinetics ; intravenous infusion ; healthy volunteers
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The plasma levels of hexobarbital in humans were determined during and after a 30-min or 60-min zero-order intravenous infusion. Hexobarbital kinetics could be described by conceiving the body to exhibit two compartments. The plasma concentrations were fitted to the postinfusion equation and the parameters intrinsic to the two- compartment open model were estimated. The elimination half-life varied considerably among the 14 individuals (160–441 min), which could mainly be explained by the greatly varying metabolic clearance of the compound (123–360 ml /min). The apparent volume of distribution per kilogram of body weight was relatively constant (1.10±0.12 liters/kg).

    Aussagen der Theorie von Kraichnan für die isotrope hydromagnetische Turbulenz (1962)
    Springer
    The European physical journal 169 (1962), S. 151-165

    Topics: Physics
    Notes: Abstract The theory ofKraichnan is applied to quasi-stationary isotropic hydromagnetic turbulence. The average infinitesimal-impulse-response functionsg(k, τ), g m (k, τ) and the time-correlationsr(k, τ), r m (k, τ) are evaluated by the non-local direct-interaction approximation within the inertial range. For the range of ohmic but no viscous dissipation it is found that the magnetic energy spectrumE m (k) obeys aE(k)k −2-law in accordance with results ofGolitsyn andMoffatt.

    Notes: The kinetics of the dibutyltin dilaurate catalyzed bulk polymerization of 4,4′-diphenylmethane diisocyanate (MDI) with poly-∊-caprolactone were studied by infared spectroscopy and adiabatic temperature rise. The overall reaction order was found to change from 3/2 to 2 with increasing temperature. At temperatures above 80°C, the order with respect to catalyst was found to decrease with concentration from 1 to 1/2. The results were consistent with a Michaelis Menten type kinetic scheme.
