    Notes:
    The Helicity Injected Torus [HIT-II: T. Jarboe et al., Phys. Plasmas 5, 1807 (1998)] is a low-aspect-ratio tokamak capable of both inductive (ohmic) and Coaxial Helicity Injection (CHI) current drive. HIT-II is modest in size (major radius R=0.3 m, minor radius a=0.2 m, and on-axis toroidal field of up to 0.5 T), but has demonstrated 200 kA of toroidal plasma current, using either CHI or induction separately. The loop voltage, boundary flux, and plasma equilibrium are controlled by a real-time flux feedback system. HIT-II ohmic plasmas exhibit reconnection events during both the current ramp-up and decay, events that relax the current profile while conserving the magnetic helicity. A new operating regime for CHI plasmas, using a double-null divertor (DND) boundary flux, has been explored. DND CHI plasmas exhibit good shot-to-shot reproducibility, low impurity content, minimal shorting current in the absorber region, and EFIT-reconstructed equilibria consistent with significant closed-flux core regions [EFIT: L. Lao et al., Nucl. Fusion 25, 1611 (1985)]. HIT-II DND CHI discharges also exhibit a continuous n=1 mode at the outer midplane, a mode that has been correlated experimentally with current-profile relaxation. A detailed explanation of helicity injection current drive has been developed, which is consistent with experimental observations of HIT and HIT-II discharges. According to this mechanism, asymmetric distortion of the n=1 mode structure generates current drive in the core plasma by dynamo action, relaxing the CHI-driven current profile. © 2002 American Institute of Physics.

    Notes:
    The transient internal probe (TIP) diagnostic is a novel method for probing the interior of hot magnetic fusion plasmas. In the TIP scheme, a probe is fired, using a two-stage light gas gun, through a hot plasma at velocities up to 5 km/s, and makes direct, local measurements of the internal magnetic field structure. The data are relayed to the laboratory optical detection system using an incident laser that is directed through a Faraday rotator payload acting as a magneto-optic sensor. Ablative effects are avoided by minimizing the probe size, limiting the time that the probe is in the hot plasma, and encasing the probe with a diamond cladding. The degree to which the diamond probe cladding is susceptible to ablative effects will determine the plasma density and temperature regime in which the TIP diagnostic can be used. If the TIP suffers significant ablation it is an indication that the diagnostic is not usable on this hot and dense of a plasma (or that greater velocity must be imparted to the probe to further minimize the time that it is in the plasma). A quantitative experimental study of the ablation rates of diamond is planned as part of the TIP development. The integrated TIP system will be functional in 1992 and installed on the Helicity Injected Torus (HIT) [T. R. Jarboe, Fusion Tech. 15, 9 (1989)] at the University of Washington.

    Notes:
    Seventeen patients with common venous ulcers, from which Candida species were isolated, were treated with nystatin incorporated into an ointment applied once per week before the application of compressive bandages. In half the patients the regime was used for 1 month, followed by a month with the same treatment but without nystatin; this procedure was reversed in the remainder of the patients.Regular mycological examination showed that the yeast was eradicated in all the cases when nystatin was used, but the clinical response was not closely related to the disappearance of the yeast. Sixteen patients were then followed up for a year, or until the ulcers had healed, and were treated with nystatin for as long as the yeast was shown to be present. This treatment did not have any obvious clinical effect on the rate of healing.

    Notes:
    Pinhole-free, pseudomorphic CoSi2 films with thicknesses from 1.3 to 16.4 nm have been grown epitaxially on Si(111) by sequentially depositing thin Co and Si films at room temperature, and subsequently annealing the resulting a-Si:Co2Si:Si(111) structure at 670 K. The film morphology is studied by high-resolution Rutherford backscattering, transmission electron microscopy, and reflection high-energy electron diffraction. The absence of pinholes in the as-grown layers is explained by a lowering of the barrier of CoSi2 nucleation owing to the presence of amorphous Si. Upon further heating the films remain uniform up to a temperature of 1000 K. Above that temperature the layers break up in islands, which corresponds with the thermodynamically most stable morphology. The lattice strain in pseudomorphic layers is found to persist even after islanding.

    Notes:
    We describe a new ultrahigh-vacuum facility which is being used for studies of solid surfaces. The target chamber is attached via a differentially pumped beamline to a 2-MV Van de Graaff accelerator, and includes: (1) instrumentation for high-energy ion backscattering and channeling studies and nuclear reaction analysis, (2) a 100-mm radius hemispherical analyzer for photoemission studies, and (3) low-energy electron diffraction (LEED) optics.

    Notes:
    We discuss the fluctuation characteristics expected from MHD modes including ballooning modes and show how they can be studied using measurements of ECE. A novel technique, ECE correlation radiometry, which enables the location and spatial structure of long wavelength (L(approximately-greater-than)0.1×a) MHD modes to be determined, is described. Measurements on JET with a 44-channel ECE heterodyne radiometer are presented and show the existence of high-frequency (high n number) MHD modes under high poloidal beta, pellet-enhanced performance (PEP) plasma conditions. Similar measurements are planned for PBX-M and the measurement system is described.

    Notes:
    Methods for evaluating the hazards associated with noncancer responses with epidemiologic data are considered. The methods for noncancer risk assessment have largely been developed for experimental data, and are not always suitable for the more complex structure of epidemiologic data. In epidemiology, the measurement of the response and the exposure is often either continuous or dichotomous. For a continuous noncancer response modeled with multiple regression, a variety of endpoints may be examined: (1) the concentration associated with absolute or relative decrements in response; (2) a threshold concentration associated with no change in response; and (3) the concentration associated with a particular added risk of impairment. For a dichotomous noncancer response modeled with logistic regression, concentrations associated with specified added/extra risk or with a threshold responses may be estimated. No-observed-effect concentrations may also be estimated for categorizations of exposures for both continuous and dichotomous responses but these may depend on the arbitrary categories chosen. Respiratory function in miners exposed to coal dust is used to illustrate these methods.
