    Ammonia Diffusion through Nalophan Double Bags: Effect of Concentration Gradient Reduction by Selena Sironi, Lidia Eusebio, Laura Capelli, Emanuela Boiardi, Renato Del Rosso

    Published 2014-01-01
    “…The losses observed for storage conditions and times as allowed by the reference standard for dynamic olfactometry (EN 13725:2003) indicate that odour concentration values due to the presence of small molecules may be significantly underestimated if samples are not analysed immediately after sampling. A diffusion model was used in order to study diffusion through the bag. …”

    Nonuniformity of Diffusing Capacity From Small Alveolar Gas Samples Is Increased in Smokers by DJ Cotton, JT Mink, BL Graham

    Published 1998-01-01
    “…Because submaximal single breath washout (SBWSM) manoeuvres improve the detection of abnormalities in ventilation inhomogeneity in the lung periphery in smokers compared with traditional vital capacity manoeuvres, SBWSM manoeuvres were used in this study to measure temporal differences in diffusing capacity using a rapid response carbon monoxide analyzer.…”

    The 𝑀-Wright Function in Time-Fractional Diffusion Processes: A Tutorial Survey by Francesco Mainardi, Antonio Mura, Gianni Pagnini

    Published 2010-01-01
    “…In the present review we survey the properties of a transcendental function of the Wright type, nowadays known as 𝑀-Wright function, entering as a probability density in a relevant class of self-similar stochastic processes that we generally refer to as time-fractional diffusion processes. Indeed, the master equations governing these processes generalize the standard diffusion equation by means of time-integral operators interpreted as derivatives of fractional order. …”
