    Master equation model for solute transport in river basins: part II basin fluvial scale

    No full text
    At basin scale the physical phenomenon of diffusion involves the intricate spreading and dispersion of substances within complex systems as networks of interconnected channels, streams, and land surfaces. Understanding this process is crucial for many purposes as management and conservation of water resources. We extend the model application of our previous work (Part I, Rizzello et al. in Stoch Environ Res Risk Assess 37:3807–3817, 2023) from channel to basin scale. We use conservation of mass and momentum to formulate and apply the Master Equation system at basin scale. The results on simulated events highlight the transition of the model from channel scale to basin scale

    Lactic acid bacteria: a tool to produce bioactive peptides

    No full text
    Bioactive peptides are a very heterogeneous group of compounds that may influence several physiological functions in animals and humans. After a description of the properties of some bioactive peptides, an overview on the presence of such molecules in milk-derived products is given. The possible role of lactic acid bacteria in the release of bioactive sequences from precursor proteins is also discussed
