    “…An evaluation of the predictive ability of models for simulated data was conducted and indicated that the AMMI analysis, in general, was robust, and models adjusted by the Reversible Jump method were superior to those in which sampling was performed only by the Gibbs sampler. In addition, the RJMCMC showed greater feasibility since the selection and estimation of parameters are carried out concurrently in the same sampling algorithm, being more attractive in terms of computational time. …”

    “…BACKGROUND: Within the United Kingdom, the change from conventional to liquid based cytology (LBC) has brought with it the universal introduction of broom style samplers, as represented by the Cervex sampler. The aim of this study was to assess whether or not there were benefits associated with a change from wooden spatulae to broom style samplers for those countries where conversion to LBC might not be readily available or is not fully supported. …”

    “…Repeated measurements of NO(2 )were made using a passive diffusive sampler. A Saltzman colorimetric method using a spectrometer calibrated at 540 nm was employed to analyze the mass of NO(2 )on the collection filter that was then subjected to a mass transfer equation to calculate the level of NO(2 )for the 24 hours of sampling duration. …”
