    Relative positions of the thermal convection column and smoke plume generated from a smoldering cigarette

    MCRAE D.D.; JENKINS R.W. Jr.
    Philip Morris USA, Research Center, Richmond, VA, USA
    The relative positions of the thermal convection column and the smoke plume from a variety of smoldering cigarettes were measured using a combination of schlieren and visual optical systems. The schlieren technique is an optical method used to...

    Philip Morris Europe, R&D, Neuchâtel, Switzerland.
    Three fungal strains isolated from tobacco were cultured on tobacco water extracts. In these cultures, the mycelium weight was shown to be correlated with the concentration of a steroid, ergosta-5,7,22-trien-3beta-ol (ergosterol ). This steroid is...

    Application of Fourier transform infrared evolved gas analysis (FT-IR-EGA) to the study of tobacco curing

    FENNER R.A.; LYONS-HART J.; LEPHARDT J.O.
    Philip Morris USA, Research Center, Richmond, VA, USA
    FT-IR evolved gas analysis, a non-isothermal pyrolysis technique, is used to probe the changes in tobacco leaf composition which occur during flue- and air-curing. A unique perspective of major enzymatic processes and their dependencies on curing...

    The efficacy of Kabat R as a surface spray on oriental tobacco bales for control of the cigarette beetle Lasioderma serricorne (F.) (Coleoptera: anobiidae)

    FAUSTINI D.L.; LEHMAN R.M.; LONG J.S.
    Philip Morris USA, Research Center, Richmond, VA, USA
    Methoprene, a synthetic juvenile hormone analogue, was shown to have the capability of preventing the cigarette beetle Lasioderma serricorne (F.) from propagating when applied to the outside of packaged Oriental tobacco bales. Control was achieved...
