    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...

    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...

    Estimation of the state of nitrogen nourishment of tobacco using the N-tester

    KOWALCZYK-JUSKO A.; KOSCIK B.
    University of Agriculture, Lublin - Institute of Agricultural Sciences, Zamosc, Poland.
    The purpose of this work, based on a three years of field experiment, was to inspect whether it is possible to use a chlorophyll meter in fixing the nitrogen doses used in growing flue-cured tobacco. The relationship between the capacity of nitrogen...

    Influence of aqua terra hydrogel on growth, development and yield of light cigarette tobacco

    KOSCIK B.; KOWALCZYK-JUSKO A.
    University of Agriculture, Lublin - Institute of Agricultural Sciences, Zamosc, Poland.
    The aim of introductory field and pot experiments which were carried out in Zamosc in the years of 1995-1997 was to study the influence of Aqua Terra hydrogel on the growth, development and yield of light cigarette tobacco. Hydrogels are substances...
