    VERRON T.(2); BRY X.(1); CAHOURS X.(2); COLARD S.(2)
    (1) UM2, University Montpellier 2, France; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    In 2012, we evaluated and presented at the CORESTA Congress [1] the probable impact of emission ceilings as proposed by the joint working group of the WHO Study group on Tobacco Product Regulation (TobReg) [2] using experimental data and we demonstrated ...

    Heavy metals are naturally present in soils, or can be brought by agricultural practices or spread out by human activities. Some of them are essential for plant development. Cadmium is a non-essential heavy metal which is classified in Group 1 (= known ...

    THEME-SEER: Multidimensional exploratory technique to explore the generation process of smoke compounds

    BRY X.(1); VERRON T.(2); CAHOURS X.(2); TEILLET B.(2)
    (1) I3M, UM2, Montpellier, France; (2) SEITA, Imperial Tobacco Group, Fleury-les-Aubrais, France
    In 2011, we presented at the 2011 CORESTA SSPT Meeting (Graz) [1] a new approach to path modelling based on system extended multiple covariance criteria. We showed why THEME-SEER may be preferred to current methods using either criteria based on ...

    Lowering TSNAs through nitrite reductase activity

    DAVENPORT S.E.; FORSYTH K.; TULLY L.; LISTER R.; LE LAY P.; MAUNDERS M.; SANCHEZ-TAMBURRINO J.P.
    Advanced Technologies Ltd., Cambridge, UK (holding of British American Tobacco Ltd.)
    Tobacco specific nitrosamines (TSNAs) are compounds in tobacco that have been shown to be carcinogenic. TSNAs are formed by the nitrosation of tobacco alkaloids with the main nitrosating agent believed to be nitrite. High levels of nitrate accumulation ...

    Tobacco Biotechnology: a tool for business solutions

    SANCHEZ-TAMBURRINO J.P.; EDWARDS K.; JONES L.; DAVENPORT S.E.
    Advanced Technologies Ltd., Cambridge, UK (holding of British American Tobacco Ltd.)
    Over the past 20 years, genetic modification and molecular breeding has been successfully used in many different crops to provide agronomic advantages (i.e., herbicide resistance, insect tolerance). However there are many other areas where it can be used ...

    Using a structural model based on a class of generalized covariance criteria, to explore the generation process of smoke compounds

    BRY X.(1); REDONT P.(1); VERRON T.(2); CAHOURS X.(2)
    (1) I3M, UM2, Montpellier, France; (2) SEITA Imperial Tobacco Group, Fleury-les-Aubrais, France
    Our aim is to explore a structural model: several variable groups describing the same units are assumed to be structured around latent dimensions that are linked together through a linear model that may have several equations. This type of model is ...
