    Comparisons of the composition of tobacco smoke and the smokes from various tobacco substitutes

    GREEN C.R.; SCHUMACHER J.N.; LLOYD R.A. Jr.
    Charles GREEN, 430 Burkeridge Court, Winston-Salem, NC 27104-2602, USA
    By the late 1970s, eight technologies in the design of a "less hazardous" cigarette were classified as significant. The eight included: The tobacco blend, the filter tip, filter-tip additives, reconstituted tobacco sheet, paper additives, air ...

    Differences in the chemical composition of the particulate phase of inhaled and exhaled cigarette mainstream smoke

    MOLDOVEANU S.C.; ST. CHARLES F.K.
    R.J. Reynolds Tobacco Company, R&D, Winston-Salem, NC, USA
    In this study, a comparison between the chemical composition of the particulate-phase of exhaled smoke and that of smoke generated with a smoking machine has been performed. For this purpose, eight human subjects smoked a common Lights (10.6 mg 'tar ...

    Determination of nicotine in smoke condensate by ion chromatography coupled to ultraviolet detection

    GEISS O.; KOTZIAS D.
    European Commission, Joint Research Centre, Institute for Health and Consumer Protection, Ispra (Va), Italy
    A new method for the determination of the nicotine content of tobacco smoke condensate is described. The smoke condensate of the mainstream smoke was collected in a glass fibre filter trap and dissolved in isopropanol. The nicotine content of an aliquot ...

    The expansion of tobacco and its effect on cigarette mainstream smoke properties

    GREEN C.R.; SCHUMACHER J.N.; RODGMAN A.
    Charles GREEN, 430 Burkeridge Court, Winston-Salem, NC 27104-2602, USA
    For nearly four decades, the expansion of tobacco has heen recognized as one of eight technologies significant in the design of a "less hazardous" cigarette. The data previously presented at scientific conferences and/or published in several ...

    A model for the prediction of tobacco temperature and oxygen profiles in warehouse aging process

    ZHEN Y.; CHIPLEY J.; DOW A.
    U.S. Smokeless Tobacco Inc, Nashville, TN, USA
    A mathematical model on the temperature and oxygen profiles for the tobacco warehouse aging process was formulated and solved by numeric analysis. The mode parametres were obtained using the non-linear regression method by fitting several years measured ...

    Changes in the expression of genes implicated in phenylpropanoid metabolism are coupled with calcium-based signalling systems in tobacco cells challenged with elicitors

    AMELOT N.; BRIERE C.; CARROUCHE A.
    We analysed in BY2 cell cultures the relationships between cytosolic calcium variations and phenylpropanoid gene expression in response to two biotic stimuli: cryptogein, a polypeptide, and oligogalacturonides (OGs). We have been able to show that both ...
