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 inverse problem for plane wave excitation of a small soft ellipsoidal boss on a rigid base plane is considered. It is shown that one measurement of the leading order low-frequency coefficient of the real part of the specular scattering amplitude

The inverse problem for low‐frequency plane wave excitation of a small rigid ellipsoid is considered. It is shown that six measurements of the leading‐order low‐frequency coefficient of the imaginary part of the forward scattering amplitude are

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

An experiment was conducted on a fertile Wakanui silt loam in 1991/1992 examining yield and water use of five perennial pasture grass species, Grasslands Hakari mountain brome (Bromus sirchensis), Grasslands Wana cocksfoot (Dactylis glomerata), Grass
