    Notes: A large Faraday rotation is reported for Rh4+-substituted magnetic garnets in the near-infrared wavelength region. The Faraday rotation at 0.9 μm is about seven times larger than that in yttrium iron garnet by substituting Rh4+ ions of only 0.13 per formula unit at room temperature. From the electronic state calculations of a (Rh4+O62−)8− octahedral cluster performed by using an unrestricted self-consistent field–scattering wave–X α method, the origin of the Faraday rotation is attributable to the charge transfer transitions of an electron from O 2p to Rh 4d orbitals, or t1un(2p)→t2g*(4d) and t2un(2p)→t2g*(4d) transitions. Based on this assignment, the Faraday rotation spectrum is calculated by taking into account the spin–orbit interaction and the molecular field from iron magnetizations in the magnetic garnet. © 1997 American Institute of Physics.

    Use of a semiconductor detector for measurement of high energy end loss ions from a tandem mirror (1997)

    Notes: A semiconductor detector is applied for measurement of high energy end loss ions (E≥15 keV) from a tandem mirror. Its energy sensitivity to protons calibrated by using a monochromatic ion source is found to be the same as that to electrons. The semiconductor detector is installed on an end wall of the GAMMA 10 tandem mirror and high energy end loss ions are observed with the detector when ions in the confinement region are strongly heated by ion cyclotron waves. Counts of high energy end loss ions are closely related with a diamagnetic signal representing ion heating. The energy of the end loss ions spreads with time and attains to 50–60 keV. Time behavior of the ion count suggests that unknown loss processes other than classical Coulomb scattering are relevant to ion end loss. © 1997 American Institute of Physics.

    In situ calibration of microchannel-plate-based x-ray pinhole camera for observation of magnetically trapped plasma (1997)

    Notes: The electronic amplification gain of a microchannel plate (MCP), as employed for detector and image amplifier of an x-ray pinhole camera, tends to decrease as the output current increases, posing problems both in quantitative analyses and in construction of a three-dimensional emissivity distribution. We report that the output-current dependent MCP gain is described in a simple empirical formula that is determined by an in situ calibration experiment using a steady-state low-temperature discharge plasma. We examine the validity of the formula affirmatively in correcting raw data of x-ray images of magnetically trapped hot plasma. It is also demonstrated that the correction leads to a three-dimensional distribution of soft x-ray emissivity in a quadrupole-mirror-trapped hot plasma that is consistent with other indirect measurements. © 1997 American Institute of Physics.

    Thermographic temperature determination of gray materials with an infrared camera in different environments (1997)

    Notes: In conventional infrared (IR) thermographic cameras it is normally assumed that the ambient temperatures of optical objects are the same as the temperature determined at the camera head. In increasing cases of application of thermography, this assumption is not always satisfied, and often leads to erroneous results. In this article, we propose a determination scheme of the true temperature of such objects in an explicit form of equation to be solved by combining the readout temperature of the camera with a response function of the camera to a blackbody. The equation can be used to determine optical properties of components in an IR system. It also works to evaluate the contribution coming from each element along the optical path. Though the scheme is written in a form applicable to a specific camera among commercial products, it can be modified so that conventional IR cameras are conveniently used for thermographic determination of the temperature of gray objects in exotic environments. © 1997 American Institute of Physics.

    Non-relativistic response function for higher harmonic electron cyclotron resonance heating (1997)

    Notes: A response function [Y. Kiwamoto et al., Phys. Plasmas 1, 834 (1994)] for higher harmonic cyclotron resonance heating is constructed through the analysis of electron trajectory under harmonic heating in an inhomogeneous magnetic field. General expressions of orbital displacement and energy gain for higher harmonic resonance are obtained. Phase-averaged energy gain of electrons by n-th harmonic electron cyclotron resonance heating (ECRH) is larger by a factor of n, if the effect of the orbital displacement from the unperturbed orbit is correctly included, than that evaluated based on an unperturbed orbit assuming small k⊥ρ. The energy gain for finite k⊥ρ is also obtained. These results are confirmed with a numerical calculation for second harmonics. © 1997 American Institute of Physics.

    Plug potential formation in a tandem mirror (1997)

    Notes: It is suggested experimentally that a plug potential forms in a different mechanism from the originally expected scenario in the present tandem mirror [T. Tamano, Phys. Plasmas 2, 2321 (1995)]. That is, the formation requires only electron cyclotron resonance heating experimentally. In this manuscript, therefore, the plug potential with continuous axial profile is analytically shown to be created with the plausible ion and electron distribution functions in a present tandem mirror, i.e., passing ions, mirror trapped ions in the thermal barrier, passing electrons, φ-trapped electrons in a plug potential, and the small amount of ions that are born around the plug region.© 1997 American Institute of Physics.

    Cellular origin and ultrastructural changes of regenerating shoots from tobacco (Nicotiana tabacum) internodes cultured in vitro (1997)

    Notes: Ultrastructural changes were studied during shoot formation from tobacco internode slices cultured on Murashige and Skoog's (MS) basal medium plus 0.54 μM naphthaleneacetic acid, 0.44 μM 6-benzyladenine, 3% (w/v) sucrose and 0.8% (w/v) agar. Dramatic structural changes were observed in cortical cells below the internodal epidermis, especially those immediately centripetal to the stomata, by light and scanning electron microscopy. Transmission electron microscopic investigation revealed conspicuous structural changes to plastids at each stage during shoot regeneration. To confirm the significance of the cortical cells in shoot regeneration, protoplasts were isolated from them and shoots regenerated successfully. The ability of single cortical cell protoplasts to differentiate into shoots was demonstrated.

    Notes: Fifty-two cases of non-Hodgkin's lymphoma (ahl) In The oral and maxillofacial region, comprising 31 submucosal (extra-nodal) and 21 cervical node Nhls, Were investigated. The patients' ages ranged from 5 to 86 years, with a bimodal age distribution among young people below 12 years of age (average 8 years) and in those aged 30 years or older (average 60.3 years). The male-to-female gender difference ratio was 1.3:1. Patients presented with swelling as the major symptom. Histologically. diffuse, large cell malignant lymphoma was the most frequent type and 67.9″.!’of lymphomas were of intermediate malignancy as defined by the Working Formulation for Clinical Usage. All submucosal lymphomas showed diffuse proliferation patterns, although follicular proliferation was identified in 5 of the 21 nodal lymphomas. Immunohislochemistry showed that the B-cell type was predominant, especially in nodal lymphomas.
