    Temperature dependence of Auger lifetime in heavily doped Hg1−xCdxTe (1993)

    Notes: An expression for Auger lifetime as a function of temperature has been derived for a heavily doped Hg1−xCdxTe in the presence of a nonparabolicity of band structure, band gap narrowing, and carrier degeneracy. It is utilized to study the variation of Auger lifetime with temperature through numerical analysis.

    Transport mechanism in semiconducting glassy silicon vanadates (1993)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Measurements are reported for the electrical conductivity of the semiconducting glassy silicon vanadates in the temperature range 80–400 K. The experimental results have been analyzed with reference to the existing theoretical models of hopping conduction. The analysis shows that at high temperatures the conductivity data are consistent with Mott's model [J. Non-Cryst. Solids 1, 1 (1968)] of phonon-assisted polaronic hopping, while Mott's variable range hopping model [Philos. Mag. 19, 835 (1969)] is valid at low temperatures. The small polaron model of Schnakenberg [Phys. Status Solidi 28, 623 (1968)] is also found to be consistent with the temperature dependence of the conductivity. The temperature dependence of the conductivity can also be interpreted in the framework of the percolation model proposed by Triberis and Friedman [J. Phys. C 18, 2281 (1985)]. The analysis of the conductivity data also indicates that the hopping in these vanadate glasses occurs in the nonadiabatic regime.

    Pancreatic pseudocyst (1993)

    Notes: Summary An 18-year-old male who developed a pancreatic pseudocyst during the active phase of polyarteritis nodosa is described. Cytotoxic therapy with cyclophosphamide and prednisolone was unable to control the manifestation of this disease, and he required percutaneous drainage of the pseudocyst. The drainage resulted in complete resolution.

    An experimental investigation on impact response of laminated composite beams (1993)
    Springer
    Experimental mechanics 33 (1993), S. 159-163

    ISSN: 1741-2765
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Experiments based on a new technique were carried out to study the response of glass/epoxy laminated composite beams subjected to impact loading. A number of glass/epoxy composite beams with different fiber orientations, spans, thicknesses, and support conditions were impacted with an instrumented impact hammer and the responses were picked up using an accelerometer in conjunction with a spectrum analyzer. Free vibration test for some sample beams were also carried out to determine their fundamental frequencies.

    Possibilities for francium spectroscopy in a light trap (1993)
    Springer
    Hyperfine interactions 81 (1993), S. 197-202 
    Details
    ISSN: 1572-9540

    Topics: Physics
    Notes: Abstract An experimental program is under way to capture neutral francium atoms in a magneto-optic trap. Production and transport of the radioactive Fr atoms near to the trapping region have been tested, with a steady state of 107 atoms. If one hundred atoms are captured from the Maxwell-Boltzmann distribution into a magneto-optic trap, this will be a sufficient number for spectroscopy of the unknown excited states. These measurements would then open the path to investigations of parity-violating transitions in francium.
