    Technique for measurement of resistivity versus simultaneous temperature and pressure in a tetrahedral anvil press (1988)

    Notes: Electrical resistivity measurements of materials as a function of pressure and temperature simultaneously are valuable indicators of structural phase changes and of electronic properties. Such measurements are difficult, however, and relatively few materials have been studied in this way. A sample holder for a tetrahedral anvil apparatus has been modified so that such measurements may be made. The calibration of the Pt/Pt10Rh thermocouple used to determine the temperature of the sample was found to be affected by pressure, and preliminary recalibration of this thermocouple under pressure was performed. Reasonable agreement was found between the phase diagram of CdTe determined with the apparatus used in this study and that previously published.

    Description / Table of Contents: Contents Analytical expressions of the eddy current dispersion of the complex permeability for ferromagnetic bodies obeying the Rayleigh law and with shapes mentioned in the title are derived for low and moderate magnetic fields. They are valid in the whole frequency range. For low frequencies formulas for the real and the imaginary part of the permeability are presented, which permit the estimation of the error involved in the calculation of the power losses in the case of a simple superposition of eddy current and hysteresis losses.
    Notes: Übersicht Es werden analytische Ausdrücke der wirbelstrombedingten Dispersion der komplexen Permeabilität für ferromagnetische, dem Rayleighgesetz gehorchende Körper mit der in der Überschrift genannten Geometrie im Falle schwacher bis mäßig starker Magnetfelder abgeleitet, die für den gesamten Frequenzbereich gültig sind. Für niedrige Frequenzen werden Formeln für Real- und Imaginärteil der Permeabilität angegeben, die eine Abschätzung des Fehlers bei der Berechnung der Verlustleistung durch einfache Superposition von Wirbelstrom- und Hystereseverlusten gestatten.

    Chronic subdural haematomas treated by enlarged burr-hole craniotomy and closed system drainage retrospective study of 120 patients (1984)

    Notes: Summary In a retrospective study 143 chronic subdural haematomas in 120 patients were analysed. 64% of patients were 60 years or older. All haematomas were operated on by slightly enlarged burr-hole craniotomy and closed system drainage for three days postoperatively. A history of trauma was present in 63%. Most frequent symptoms in the older patients were mental changes and impaired consciousness. Postoperative mortality (within one month after surgery) was 4%. After a follow-up period of up to 2.5 years after surgery, 69% were neurologically normal, 20% had only minor complaints or slight deficits. Postoperative CT scans showed a gradual re-expansion of the compressed brain during the 2–3 weeks following haematoma removal.

    Enzymatic cleavage prior to antibody incubation as a method for neuropeptide immunocytochemistry (1982)

    Notes: Summary When deplasticized Epon sections were treated with endo- and/or exopeptidases prior to incubation with antibodies, the neuropeptide immunoreactivity of secretory nerves was often altered in a predictable way. Cleavage of neurosecretory material in octopus nerves by trypsin and carboxypeptidase-B enhanced enkephalin-like immunoreactivity, while Molluscan neuropeptide-like immunoreactivity was prevented by tryptic cleavage. The enzyme effects indicated the occurrence of a heptapeptide (Tyr-Gly-Gly-Phe-Met/Leu-Arg-Phe) that contains both the enkephalin and the Molluscan neuropeptide sequence. Vasopressin terminals of the rat neurohypophysis, which presumably contain enkephalin precursor sequences, exhibited enkephalin-like immunostaining after tryptic cleavage. ACTH/β-endorphin cells of the rat intermediate pituitary, which synthesize the enkephalin sequence at the N-terminus of β-endorphin, exhibited enkephalin-like immunoreactivity when sections were treated with α-chymotrypsin or trypsin, but not after incubation with leucine-aminopeptidase or carboxypeptidase-B. Enkephalin-like immunostaining could not be induced in any way in ACTH/β-endorphin cells of the anterior pituitary. Enzymatic cleavage may give additional information in immunocytochemical localization studies on neuropeptide sequences in secretory nerves and hormonal granules.

    Pharmacokinetics of atenolol in relation to renal function (1981)
    Springer
    European journal of clinical pharmacology 19 (1981), S. 65-71

    ISSN: 1432-1041
    Keywords: atenolol ; haemodialysis ; renal failure ; pharmacokinetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The pharmacokinetics of atenolol were determined following acute intravenous and chronic oral administration to 20 subjects with a glomerular filtration rate (GFR) between 5 and 113 ml/min. Plasma levels in a further 5 patients on haemodialysis were measured after intravenous treatment. The mean half life of elimination increased from 5.9 h in patients with normal renal function to 42.1 h in preuraemic patients (GFR 〈10 ml/min) following a single i. v. dose. The half life of elimination following chronic oral administration was not significantly different. Mean peak plasma concentrations increased from 540 ng/ml in patients with normal renal function to 1493 ng/ml in preuraemic patients following chronic oral treatment with 100 mg/day. The mean half life of elimination during a single haemodialysis treatment was 4.3 h. In patients with a GFR 〉30 ml/min the normal daily dose of atenolol should be employed, in patients with a GFR between 10 and 30 ml/min the dose should be reduced by half, and in patients with a GFR 〈10 ml/min a reduction by three quarters of the normal dose is recommended.

    Mutation induction in spores ofBacillus subtilis by accelerated very heavy ions (1986)

    Notes: Summary Mutation induction (resistance to sodium azide) in spores ofBacillus subtilis was investigated after irradiation with heavy ions from Neon to Uranium with specific particle energies between 0.17 and 18.6 MeV/u. A strong dependence of the mutation induction cross section on particle charge and energy was observed. From the results it was concluded that mutation induction in bacterial spores by very heavy ions is mainly caused by secondary electrons.

    Heterosis in the flour moth, Ephestia kühniella (1984)

    Details
    ISSN: 1573-6857

    Topics: Biology
    Notes: Abstract Four lines of Ephestia kühniella each homozygous for one of three different allozyme alleles at the Est-2 locus and two alleles at the Adh locus were crossed in order to study the extent of somatic, reproductive and adaptive heterosis in F1 hybrids in comparison with the mean performance of the simultaneously reared inbred parent lines. With regard to adult weight and wing length (somatic heterosis) hybrids exhibit maximally 20% (males 10%) and 9% heterosis, respectively. As concerns the production of eggs and hatched larvae (reproductive heterosis) hybrids exceed the parental mean by 90% and 200%. Adaptive heterosis is realized by a shorter development period of the hybrids (maximally by 30%) as well as by significant lower variance of all metrical characters studied. In the F2 the degree of heterosis diminishes. There is neither an excess of heterozygotes among the segregating allozyme genotypes nor superior performance of the heterozygotes concerning any one of the traits studied. Therefore, it is concluded that the pronounced heterosis in F1 is not a single-gene-heterosis operating at the Est-2 and the Adh-locus.

    Notes: Abstract The production cross sections for the Λ, Σ0, Ξ−, Σ0 (1385), Ξ0 (1530) and Ω− hyperons have been measured, both in the continuum and in direct ϒ decays. Baryon rates in direct ϒ decays are enhanced by a factor of 2.5 or more compared to the continuum. Such a large baryon enhancement cannot be explained by standard fragmentation models. The strangeness suppression for baryons and mesons turns out to be the same. A strong suppression of spin 3/2 states is observed.

    Notes: Abstract The correlations betweenp $$\bar p$$ , $$\Lambda \bar \Lambda $$ , $$\Xi ^ - \bar \Lambda $$ and $$\Lambda (1520)\bar \Lambda $$ baryons have been measured ine + e − continuum events and in direct Ψ decays. The observed correlations exclude the production of point-like diquark-antidiquark pairs as the dominant source of baryons. Information concerning angular momentum compensation follows from the observed $$\Lambda (1520)\bar \Lambda $$ correlation.
