    Notes: Abstract  A long-term regeneration system for garlic (Allium sativum L.) clones of diverse origin was developed. Callus was initiated on a modified Gamborg's B-5 medium supplemented with 4.5 μM 2,4-D and maintained on the same basal medium with 4.7 μM picloram+0.49 μM 2iP. Regeneration potential of callus after 5, 12 and 16 months on maintenance medium was measured using several plant growth regulator treatments. The 1.4 μM picloram+13.3 μM BA treatment stimulated the highest rate of shoot production. Regeneration rate decreased as callus age increased, but healthy plantlets from callus cultures up to 16-months-old were produced for all clones. Regeneration of long-term garlic callus cultures could be useful for clonal propagation and transformation.

    Notes: Abstract Root segments from shoot tip-derived plantlets of the garlic (Allium sativum L.) clones `DDR7099', `PI383819', and `Piacenza' were utilized as an explant source for continuous, friable callus production. The best callus production occurred on root segments initially cultured on medium with 4,5 μm 2,4-dichlorophenoxyacetic acid (2,4-D) for 8 weeks, then subcultured to medium with 4.7 μm 4-amino-3,5,6-trichloropicolinic acid (picloram) +0.49 μm 6-(γ-γ-dimethylallylamino)purine (2iP) for 8 weeks. Embryogenic, friable callus was transferred to liquid medium for 1 month and then transferred to solid regeneration medium for 14 weeks. The best shoot and root regeneration (85.3% and 35.8%, respectively) occurred on 4-month-old calli from the clone `DDR7099'. In all clones, regeneration rate decreased as callus age increased.

    Die Reduktion von Kupfersulfat in wässeriger Lösung durch Natriumhypophosphit und Natriumhydrosulfit (1913)

    Notes: Aus den Versuchen ergibt sich, daß Cuprohydrid bei der Reaktion zwischen Kupfersulfat und unterphosphoriger Säure entsteht, daß aber die Reinheit des Produktes von begrenzten Versuchsbedingungen, besonders von Temperatur und Zeit abhängt. Die Versuche bei gewöhnlicher Temperatur zeigen, daß nach mehrstündigem Stehen das Produkt Hydrid und Oxyd enthält, und auf die Koexistenz dieser beiden Stoffe ist die Explosionsfähigkeit der trockenen Substanz bei Berührung mit Luft zurückzuführen.

    Short-lived sites in nucleate boiling (1985)
    Hoboken, NJ : Wiley-Blackwell

    Notes: An hypothesis is proposed to explain the origin of short-lived sites observed in nucleate pool boiling. Conditions are postulated under which microbubbles might circulate into the superheated liquid region and serve as the source of these nucleation sites. Consequences of this possible mechanism are examined for explanations of hysteresis effects and scatter of results in boiling research.

    Notes: The behavior of active boiling site populations was monitored for pool boiling on an electrically heated 1-mil stainless steel sheet. The boiling sites were located using a high-speed infrared camera focused on the underside of the boiling surface. Experiments were conducted to determine factors affecting the origin, concentration, and lifetime of active sites.

    Local boiling coefficients on a horizontal tube (1958)
    Hoboken, NJ : Wiley-Blackwell

    Notes: Local boiling heat transfer coefficients were experimentally determined for nucleate boiling around the outer circumference of horizontal copper tubing. The tubes used were of 16 B.W.G. hard-temper copper with outside diameters of 1 1/4 and 2 in; the liquids boiled were methanol and n-hexane. The maximum peripheral variation occurred with the 1 1/4-in. tube in methanol where an over-all ΔT of 30.2°F. gave local outside coefficients varying between 249 and 548 B.t.u./(hr.)(sq. ft.)(°F.). The minimum variation was found to occur in the same system, in which an over-all ΔT of 72.3°F. gave coefficients varying between 856 and 910 B.t.u./(hr.)(sq. ft.)(F.°). The results, plotted in polar coordinates, showed a cardioid configuration for methanol with the maximum coefficients occurring at the bottom of the tube. The n-hexane results had the general shape of horizontal ellipses with maximum coefficients occurring at the sides of the tube.

    The effect of dynamic surface tension on nucleate boiling coefficients (1960)
    Hoboken, NJ : Wiley-Blackwell

    Notes: A study was made of the effects the surface tension of aqueous solutions of surface-active agents had on the bubble-formation characteristics of these solutions. Bubbles were formed by two processes: by passing air through a horizontal orifice submerged in the solution and by nucleate boiling at an electrically heated surface. The experimental measurements taken with the air-bubble system were used to determine the nature of the surface-tension effect on air-bubble formation. This knowledge was then applied to the interpretation of boiling measurements made with the same solutions. The boiling coefficients of the Tergitol-water solution were found to vary inversely with dynamic surface tension. Boiling coefficients for Aerosol-water solutions, however, varied in a manner which could not be related to surface-tension effects.
