The evolution of shrinkage and mass during drying of kaolin and alumina green bodies was characterized.Standard practise uses a position sensor with simultaneous mass measurement.In this work an optical method was developed to follow shrinkage in two orthogonal directions.Green body samples were made by pressing of ceramic pastes.Results have been
Fishways have been developed to restore longitudinal connectivity in rivers.Despite their potential for aiding fish passage, fishways may represent a source of significant energetic expenditure for fish as they are highly turbulent environments.Nonetheless, our understanding of the physiological mechanisms underpinning fishway passage of fish is st
