    Near wakes of a circular cylinder in stratified flows (1990)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 2 (1990), S. 481-483

    Topics: Physics
    Notes: Near wakes of a circular cylinder in linearly stratified flows are experimentally investigated by means of flow visualization and measurements of vortex shedding frequencies, at Reynolds numbers 5×103–104 and stratification parameters K smaller than 1.0. The study demonstrates that as K increases from zero, the vortex shedding from a circular cylinder is progressively strengthened, while the Strouhal number becomes gradually lower than that for a homogeneous flow. At a certain critical value of K, the enhanced vortex shedding is suddenly weakened and the Strouhal number increases sharply to a high value.

    Equilibrium beta limits in Heliotron-E due to magnetic island overlap (1990)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 2 (1990), S. 2528-2530 
    Details
    ISSN: 1089-7666

    Topics: Physics
    Notes: Widths of magnetic islands induced by finite plasma pressure are computed for the Heliotron-E configuration [Phys. Rev. Lett. 53, 2242 (1984); Nucl. Fusion 27, 895 (1987)]. Equilibrium beta limits are obtained from the criterion of island overlap. Earlier experimental observations on internal disruptions in Heliotron-E are revisited.

    Assessment of risk of carotid occlusion with balloon Matas testing and dynamic computed tomography (1990)
    Springer
    Acta neurochirurgica 103 (1990), S. 122-127 
    Details
    ISSN: 0942-0940
    Keywords: Balloon Matas test ; dynamic computerized tomography ; internal carotid artery occlusion ; giant aneurysm

    Topics: Medicine
    Notes: Summary Temporary occlusion of the internal carotid artery with a balloon atheter (balloon Matas test) and simultaneous dynamic computerized tomography scanning (DCT) were performed to determine the tolerance of permanent carotid occlusion in eight cerebral aneurysm and two carotid-cavernous fistula (CCF) cases, in whom internal carotid occlusion might be necessary during operation or as a choice of treatment. All patients were evaluated by mean transit time (MTT), especially % transit time (MTT of the occluded side×100/MTT of the control side). In six patients, % transit time (%TT) was less than 155 and no neurological signs appeared after permanent internal carotid occlusion. Neurological deficit appeared when mean arterial blood pressure was 80, and disappeared when mean arterial blood pressure was 100 during the balloon Matas test in a case whose %TT was 200. Neurological deficit appeared several seconds after the balloon Matas test in a case whose %TT was 250. The critical %TT value to cause symptomatic ischaemia was 200 from our results. Therefore, it is necessary to undertake treatment such as bypass surgery for the patients whose %TT is near 200, even if the balloon Matas test was negative.

    Nuclear magnetic resonance of RCo3(R:Rare earth) (1990)
    Springer
    Hyperfine interactions 59 (1990), S. 423-426 
    Details
    ISSN: 1572-9540
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The nuclear magnetic resonance of59Co nuclei in magnetic domains of RCo3(R:Y, Nd, Sm, Gd, Tb, Dy and Ho) has been measured under external fields up to about 50 kOe at 4.2 K. To assign the observed NMR signals to each Co site, the59Co nuclear magnetic resonance of R(Co1−xNix)3 and R(Co1−xFex)3 has also been measured under the same conditions. The results of NMR studies show that the cobalt atoms at the 6c site in the light R compounds(YCo3, NdCo3 and SmCo3) and these at the 3b site in the heavy R compounds(GdCo3, TbCo3 and HoCo3) have a large orbital contribution.

    Neutron activation analysis of altered oceanic tholeiite: Variation of lanthanide concentrations with degree of alteration (1990)
    Springer
    Journal of radioanalytical and nuclear chemistry 146 (1990), S. 375-384

    Notes: Abstract Lanthanides in altered oceanic tholeiite were determined by means of instrumental neutron activation analysis. Potassium content was employed as a measure of degree of alteration. Lanthanide concentrations in moderately altered parts of tholeiite (K2O content below 1%) were identical with those in'unaltered parts while light lanthanide concentrations in more altered parts (K2O content above 1%) increased with degree of alteration.
