    Notes: Summary Nicotine, in concentrations of 5 and 25 μg/ml drinking water, given ad libitum for 10 days, dose-dependently increased lesion formation and worsened ethanol-induced ulceration in rat stomachs. Daily fluid intake and b.wt gain were not adversely affected by nicotine pretreatment.

    Sensory Evaluation of Navel Oranges Treated with Low Doses of Gamma-Radiation (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 50 (1985), S. 0

    Notes: Navel oranges from two locations in California were given low postharvest doses of gamma radiation (60 - 80 Krads) and compared with nonirradiated controls for taste, flavor, odor, firmness, degree of orange color, degree of brown blemishing, ease of peeling and intactness of the membranes on sectioning. Practiced judges were used as an analytical screening tool using minimal cross-sensory interference, while untrained subjects were used to determine whether changes might be distinguished by‘nonexperts’. Greatest differences were found for degree of blemishing, lesser differences for flavor by mouth and odor and some trends for taste, color, texture and ease of peeling.

    Rectangular and L-shaped GaAs/AlGaAs lasers with very high quality etched facets (1989)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 54 (1989), S. 493-495 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: GaAs/AlGaAs semiconductor lasers with very high quality etched facets have been fabricated. Laser facets are formed by the chemically assisted ion beam etching technique with SiO2 as the etch mask. The threshold current densities of lasers produced with this technique are almost identical to comparable lasers with one etched and one cleaved facet. L-shaped lasers, which make use of total internal reflection, have also been fabricated. The threshold current density of L-shaped lasers is similar to that of rectangular lasers with comparable cavity length.

    Neoclassical ion transport in rotating axisymmetric plasmas (1985)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 28 (1985), S. 3082-3098 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The neoclassical theory of ion transport in rotating axisymmetric plasmas is formulated. The flow speed is allowed to be of the order of the ion thermal speed. It is shown that the ion distribution function becomes Maxwellian, with temperature uniform on a magnetic surface, and the poloidal flow decays, in a few transit or collision times, in general. A drift kinetic equation is derived which is a simple generalization of the drift kinetic equation for nonrotating plasmas. The radial gradient of the toroidal angular velocity appears as a driving term like the temperature gradient. Both gradients drive the transport of toroidal angular momentum and energy, in general; Onsager relations for the two-by-two transport matrix are derived. The off-diagonal transport coefficients are shown to be zero if the magnetic field has up–down symmetry. A simple expression for the enhancement of the ion thermal conductivity in the banana regime, caused by rotation, is derived. The neoclassical viscosity is shown not to be enhanced by rotation in the banana regime, and to be small in the collisionality parameter in the collisional regime, assuming up–down symmetry. In the collisional regime, the thermal conductivity is shown to be suppressed by the effects of rotation.

    Poloidal electric field generated by electron cyclotron heating in a collisional tokamak plasma (1987)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 30 (1987), S. 830-833 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The poloidal electric field generated by electron heating in a collision dominated tokamak plasma is calculated by the adjoint method. The physical mechanism is elucidated as due to a combination of the Doppler shifted cyclotron resonance and magnetic field inhomogeneity. For uniform rf field on a flux surface, the normalized electrostatic potential is found to be much smaller than the inverse aspect ratio for realistic power levels.

    Balanced puff valve for imploding gas-puff experiments (1986)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 57 (1986), S. 1684-1686 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: The design of a fast-acting high-pressure puff valve for use in imploding gas-puff experiments is presented. By using a pressure-balanced valve design, the valve can operate at pressures up to 500 psia. Fast opening (≈200 μs) is achieved by using a fast-moving sliding hammer to open the valve. Balanced valves as well as fast-opening valves using sliding hammers are both well-known technologies; however, this design is the first one to incorporate both features in a single design resulting in a fast-acting high-pressure puff valve.

    Current-voltage characteristics of n-amorphous low-pressure chemical vapor deposited silicon films on p-crystalline silicon (1989)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 66 (1989), S. 5894-5900 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Heterojunction devices have been fabricated by a low-pressure chemical vapor deposition technique whereby n-type amorphous or microcrystalline silicon films were grown on p-type crystalline silicon substrates. Heterostructures produced under various conditions of thin film deposition were subjected to detailed I-V curve analysis. It is seen that for amorphous-crystalline heterojunctions the current transport is through tunneling in the low bias range and limited by electron-hole recombination in the high bias range. For the microcrystalline-crystalline junctions however, recombination current at the interface dominates the current transport process. Illuminated I-V curves corresponding to films deposited at different substrate temperatures (Ts ) and dopant gas-to-silane ratios (R) show that the high values of the short-circuit current (Isc), open-circuit voltage (Voc ), and fill factor (FF) are achieved at values close to Ts ∼620 °C and R ∼4×10−3 in conformance with dark I-V characteristic data.

    Pilot Scale Aerobic Sequencing Batch Reactor for Pig Waste Treatment (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 3 (1989), S. 0 
    Details
    ISSN: 1747-6593
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: An existing aetated lagoon treating piggery waste was converted into an aerobic sequencing batch reactor (SBR). After the commissioning period, the SBR plant treated piggery wastewater containing BOD and suspended solids (SS) concentrations of 2881 mg/l and 1419 mg/1 respectively, producing an effluent having an average BOD and SS of 18.7 mg/1 and 12.3 mg/1 respectively. The volumetric loadings on the SBR and the process were similar. However, the SBR process operated at a lower mixed liquor suspended solids (MLSS) concentration and shorter sludge retention period. Although the capital and operating costs of the SBR are higher than for the aerated lagoon, the simplicity of operation, the high BOD and SS removal efficiency, and the small land requirement make this type of process an attractive treatment option, particularly in places where land supply is limited and expensive.
