    Effect of natural zeolite application and K2O on yield and quality of tobacco (Nicotiana tabacum Var. Coker 347)

    RANJBAR M.; ALLIZADEH N.S.; ESFAHANY M.; KAVOUSI M.
    Guilan Tobacco Research Center, Rasht, Iran.
    Many reports have described that natural zeolite have many useful properties, such as high Cation Exchange Capacity (CEC=1-4 meq / 100 gr), ability of absorption and emission of water, ability of ammonium absorption and inhibiting of nitrate leaching ...

    Feature selection from near infrared spectra using genetic algorithms for tobacco blend recognition

    FIGUERES G.; DE SOUZA S.; REYNES C.; SABATIER R.; VIDAL B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Near infrared reflectance spectroscopy has proved to be very useful for predicting concentrations of chemical compounds in tobacco, classification or pattern recognition of cigarette blends. The resulting measurement of a sample is a whole reflectance ...

    How representative of the human smoking behaviour would be the new alternative smoking regimes? A first attempt of assessment

    MARCHAND V.; TESSIER C.; DUMERY B.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The ISO or FTC smoking conditions (35 mL- 2 s puffs, 1 puff per minute) have been more and more criticized during the last decade, especially because they would not reflect the human smoking behaviour. Their main objective was not to predict the exact ...

    A mixture experimental design with six variables and the effects on smoke components:1 - Presentation of this experimental design and of some initial results on physical characteristics of cigarettes and blends

    VIDAL B.; FIGUERES G.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    The objective of this paper is to examine the effects of six tobacco components on the chemical and physical characteristics of blends and cigarettes and particularly on the mainstream smoke yields. First of all, we will develop the philosophy of this ...

    A mixture experimental design with 6 variables and the effects on smoke components:2 - Hoffmann analytes behaviour through a mixture experimental design

    FIGUERES G.; VIDAL B.; BIESSE J.P.; BREGEON B.; LOUVET F.; MUZELLEC L.
    Altadis Research Centre, Fleury-les-Aubrais, France
    Today in the tobacco industry, one of the main scientific challenges is to understand the formation of some smoke compounds ("Hoffmann analytes"). For several years, work has been conducted in order to know the influence of cigarette design ...
