    The challenges associated with emission ceilings based on multivariate quantile

    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 ...

    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 ...

    A multiple covariance based method to explore relationships between Hoffmann analytes and several groups of physical and chemical cigarette parameters

    BRY X.; VERRON T.; CAZES P.; FIGUÈRES G.
    I3M Université Montpellier, Montpellier, France
    In this work, we studied 28 commercial Virginia and US blends described using various thematic variable groups. Our purpose was to explore the possibility of an explanatory linear model connecting structural dimensions of these groups. A group containing ...

    Influence of the origin of the cigarette paper cellulose on the smoke chemical composition and "in vitro" toxicity tests on mainstream cigarette smoke

    TROUDE V.; ACHARD S.; DESTRUHAUT S.; HAOND C.; SARABIA J.
    Altadis - Imperial Tobacco Group, Research Center, Fleury les Aubrais, France
    Nowadays, cigarette paper is made out of cellulose coming from different sources. Wood cellulose is currently very often used, but cellulose coming from different textile plants like hemp, flax, etc. were used primarily in the past and are still present ...

    Gene expression analysis of human lung cells treated with cigarette smoke

    ACHARD S.; VERRON T.; SEVESTRE O.; DUMERY B.
    Altadis - Imperial Tobacco Group, Research Center, Fleury les Aubrais, France
    Gene expression profiling is considered as a promising tool that may identify more sensitive, mechanism-based biomarkers. Such an experimental approach should provide a better understanding of the impact of chemical compounds on the intracellular ...
