    • ‘His papers include work on the stability of a parachute and fluid flow past circular and elliptic cylinders.’

    • ‘Assuming the conduits as elliptic pipes arranged in parallel, it is possible to calculate the conductivity of the xylem conduit lumina in a stem segment from their cross-sectional dimensions.’
    • ‘Whereas hyperbolic activity and elliptic motion characterizes the cab, a big rig manifests an elliptic activity and hyperbolic motion.’
