    H2S Loss through Nalophan™ Bags: Contributions of Adsorption and Diffusion by Lidia Eusebio, Laura Capelli, Selena Sironi

    Published 2017-01-01
    “…The average quantity of adsorbed H2S at 30 h is equal to 2.17 105 gH2S/gNalophan at a storage humidity of 20% and equal to 1.79 105 gH2S/gNalophan at a storage humidity of 60%. The diffusion coefficients of H2S through Nalophan, for these two humidity conditions tested, are comparable (i.e., 7.5 10−12 m2/sec at 20% humidity and 6.6 10−12 m2/sec at 60% humidity).…”

    Competitive exclusion and coexistence in a two-strain pathogen model with diffusion by Azmy S. Ackleh, Keng Deng, Yixiang Wu

    Published 2015-09-01
    “…When we assume that the diffusion rates are equal while the transmission and recovery rates are heterogeneous, then there are two possible outcomes under the condition $R_0 >1$: 1) Competitive exclusion where one strain dies out. 2) Coexistence between the two strains. …”

    Nonlinear Dynamic Analysis of New Product Diffusion considering Consumer Heterogeneity by Zhongjun Tang, Huike Zhu

    Published 2020-01-01
    “…It aims to analyze how consumer heterogeneity affects the scale and speed of new product diffusion. The proposed model showed that consumers’ characteristics and behavior combination at the microlevel lead to the diversity of nonlinear diffusion curves at the macrolevel for new products. …”
