    The effect of Ag doping on superconducting properties of the Bi-Pb-Sr-Ca-Cu-O tape fabricated by an Ag sheath (1992)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 71 (1992), S. 5997-6001

    Notes: The powder-in-tube method using an Ag sheath is applied to achieve high current capacity in the tapes of Bi-Pb-Sr-Ca-Cu-O (BPSCCO) with the high-Tc phase (Tc=110 K), by a combination process of cold working and sintering. Two kinds of the BPSCCO powder with and without Ag doping are used as the materials for tape fabrication. The morphology, structure, and critical current density Jc are investigated on the tapes by x-ray diffraction, differential thermal analysis, scanning electron microscope, magnetic susceptibility, and I-V curves. The optimum sintering conditions to obtain a maximum in the value of Jc at 77 K and 0 T are presented in the Ag-doped tapes and the nondoped ones. An improvement in the Jc vs B properties up to 1 T at 77 K is presented in the BPSCCO tape by Ag doping. The Ag doping causes neither change in the value of Tc (=110 K) nor decomposition of the high-Tc phase.

    Accessory nerve neuroma presenting as recurrent jugular foramen syndrome (1992)
    Springer
    Neuroradiology 34 (1992), S. 417-419

    ISSN: 1432-1920

    Notes: Summary We report a patient with spontaneous recovery and recurrence of a jugular foramen syndrome secondary to an accessory nerve neuroma. He showed sudden onset of unilateral palsy of the ninth, tenth and eleventh cranial nerves in 1982. He recovered almost fully and in 1990 the palsies recurred. MRI revealed a small mass in the right jugular foramen. The tumour was resected via suboccipital craniectomy, and diagnosed as a neuroma of the eleventh cranial nerve.

    Low dose irradiation for limb salvage in malignant bone tumours (1991)

    Description / Table of Contents: Résumé Nous avons étudié sur le plan clinique et anatomo-pathologique, chez 20 malades atteints de tumeurs osseuses de haut degré de malignité, la valeur de la radiothérapie à la dose de 30 Gy en complément de la chimiothérapie pré-opératoire. L'histologie des pièces réséquées chirurgicalement a montré un effet tumoricide considérable et l'encapsulement de la partie extra-osseuse de la tumeur. La radiothérapie n'a pas déterminé d'effets secondaires fâcheux. Elle paraît donc indiquée pour la conservation des membres en cas de tumeurs osseuses de haut degré de malignité.
    Notes: Summary We have assessed the value of adding low dose radiotherapy to preoperative chemotherapy in 20 patients with high grade malignant bone tumours. Histology of the resected specimens showed a considerable tumouricidal effect and a distinct capsule enclosing the extraosseous part of the tumour. There were no serious side effects.
