    Effect of peppermint and eucalyptus oil preparations on neurophysiological and experimental algesimetric headache parameters (1994)

    Notes: The effects of peppermint oil and eucalyptus oil preparations on neurophysiological, psychological and experimental algesimetric parameters were investigated in 32 healthy subjects in a double-blind, placebo-controlled, randomized cross-over design. Four different test preparations were applied to large areas of the forehead and temples using a small sponge and their effect was evaluated by comparing baseline and treatment measure. The combination of peppermint oil, eucalyptus oil and ethanol increased cognitive performance and had a muscle-relaxing and mentally relaxing effect, but had little influence on pain sensitivity. A significant analgesic effect with a reduction in sensitivity to headache was produced by a combination of peppermint oil and ethanol. The essential plant oil preparations often used in empiric medicine can thus be shown by laboratory tests to exert significant effects on mechanisms associated with the pathophysiology of headache.

    Spatial variability of the aspect sensitivity of VHF radar echoes in the troposphere and lower stratosphere during jet stream passages (1994)

    Notes: Abstract The aspect sensitivity of SOUSY-VHF-radar oblique-beam echoes from the troposphere and lower stratosphere has been examined for a number of jet stream passages during the years 1990 - 1992. When the core of the jet is overhead or nearly so, vertical profiles of the aspect sensitivity display two notable features. First, the distinction between mainly isotropic and strongly aspect-sensitive echoes in the troposphere and the lower stratosphere, respectively, often reported for measurements made during calm conditions, does not necessarily prevail in the vicinity of the jet stream. Second, echoes obtained at altitudes near the height of the horizontal wind maximum are found to be more aspect sensitive for beams directed parallel to the horizontal flow or nearly so, than for other beam directions. It is demonstrated that time-averaged horizontal wind speeds estimated from the radar data, taking into account the reduced effective oblique-beam zenith angle resulting from aspect sensitivity, may exceed uncorrected wind speeds by as much as 10 m s−1 in these circumstances. Implications for wind profiling and for describing the backscattering process are discussed. Doppler spectral widths examined for one jet stream passage are found to be narrower in a beam aligned with the horizontal wind at heights near the wind speed maximum than corresponding widths measured in a beam projected at right angles to the jet. The narrowest spectra thus coincide with the most aspect-sensitive echoes, consistent with the hypothesis that such returns result from specular backscattering processes.

    Field campaign for the comparison of SOUSY radar wind measurements with rawinsonde and model data (1994)

    Notes: Abstract A field campaign was carried out from 26 October to 7 November 1992, using the SOUSY-VHF radar and a mobile rawinsonde system installed and operated nearby to produce vertical wind profiles. The purpose of this campaign was to compare the two types of wind measurements with one another and with results from forecast models. Numerical algorithms were developed and applied to the radar data in order to eliminate random errors, correct for velocity aliasing, and calculate the effective zenith angle of the off-vertical beams. Differences between wind profiler data and rawinsonde or model results depend not only upon the errors of the different systems, but also on temporal and spatial variations of the wind field. Therefore, methods for the comparison of radar and rawinsonde data were developed which take into consideration these variations. The practical potential of these methods is demonstrated by comparisons of rawinsonde and radar wind profiles. The comparison of radar data and model output shows excellent agreement in the direction and in the speed of the wind at virtually all altitudes. An evaluation of the quality of wind profiler measurements is possible using the estimation of variance and variability of wind components.

    The saluretic effect of the thiazide diuretic bemetizide in relation to the glomerular filtration rate (1994)

    Notes: Abstract The effect of the thiazide diuretic, bemetizide, on the excretion of Na+, K+, Cl−, Ca2+, and Mg2+ in relation to the glomerular filtration rate (GFR) was studied in 17 subjects whose creatinine clearances ranged from 133 to 5 ml·min−1. After a 2-day fluid and salt balanced control period, 25 mg bemetizide given orally induced natriuresis and kaliuresis which lasted for 24 h and were proportional to the GFR of the patients. The ratio of bemetizide-induced K+/Na+ excretion was always 0.17 irrespective of individual GFR. In renal failure, bemetizide increased the fractional Na+ excretion from 3% to about 10%. Kaliuresis was associated with magnesiuria, whereas bemetizide-induced calciuresis was insignificant. The thiazide reversibly lowered GFR in all subjects.

    Notes: Abstract Using the 93.3 keV resonance in67Zn the isomer shift, the quadrupole interaction, and the anisotropy of the Lamb-Mössbauer factor (LMF) in ZnF2 single crystals have been investigated. The main component of the electric field gradient (efg) tensorV zz=+(2.18+-0.22)×1017V/cm2 andη=0.29±0.03 are derived.V zz is oriented perpendicular to the crystallographicc axis. The anisotropy of the LMF is large:f x=(2.4±0.1)%,f y=(2.3±0.2)%, andf z=(1.4±0.2)%. Ab initio Hartree-Fock cluster calculations gave a detailed description of the observed charge distribution including the orientation of the efg tensor. Using a force constant model (shell model), we solved the eigenvalue problem of the dynamic matrix and quantitatively reproduced the anisotropy of the LMF.

    Description / Table of Contents: The metal forming process is one of the complicates mechanical deformation process. Up to this time, the investigations are mainly directed to the macroscopically point of view. Metal forming models are based on continuum mechanical methods.In opposite to the continuum mechanical deformation theory is the physics of metals.It is the aim of the paper, to discuss the developed technical supposition for using the micro-visioplasticity, an new method of micro-grid application and results of micro-grid deformation using an upsetting press.
    Notes: Der Umformprozeß gehört zu den kompliziertesten Verformungsvorgängen. Bis heute wurden die meisten Untersuchungen mit makroskopischen Theorien durchgeführt. Viele der Umformtheorien basieren auf der Kontinuumsmechanik. Demgegenüber sind mikroskopisch betrachtet jedoch auch metallphysikalische Prozesse interessant.In der Arbeit werden deshalb eine Einrichtung zur Durchführung von Versuchen - die Mikrovisioplastizität nutzend - die Grundlagen und Methoden zur Herstellung von Mikrorastern sowie erste Versuchsergebnisse vorgestellt.
