Abstract Background Animal survival depends on the ability to adjust behaviour according to environmental conditions. The circadian system plays a key role in this capability, with diel changes in the quantity (irradiance) and spectral content (‘co

Six rescued grey seal (Halichoerus grypus) pups had traumatic injuries to their hind flippers; three had osteomyelitis without fractures, one had a single fracture and associated osteomyelitis, and two had multiple compound fractures and large open w

The inverse problem of determining the geometrical characteristics of a perfectly conducting ellipsoid or ellipsoidal boss from low-frequency scattering data is considered. It is shown that the orientation and semidiameters of the scatterer can be de

The inverse scattering problem for low‐frequency plane‐wave excitation of either a penetrable ellipsoid specified by its relative mass density and relative compressibility, or the corresponding ellipsoidal boss on a rigid base plane, is considere

The inverse problem of determining the semiaxes and orientation of an ellipsoidal boss on a base plane is considered. For low‐frequency plane‐wave excitation of a rigid surface, it is shown that four measurements of the leading order coefficient

The growth of peach trees planted in unridged and ridged beds on a Wakanui silt loam was compared over a 4-year period at Lincoln University, New Zealand. Unridged beds had 20 cm of topsoil above a clay subsoil, and the 3 m wide ridged beds had 40 cm
