Reasons for performing study: Arterial blood gas analysis is widely accepted as a diagnostic tool to assess respiratory function in neonates. To the authors' knowledge, there are no published reports of arterial blood gas parameters in normal neonata

Arterial blood gas analysis is widely accepted as a diagnostic tool to assess respiratory function in neonates. To the authors' knowledge, there are no published reports of arterial blood gas parameters in normal neonatal foals at altitude.To provide

To investigate the relationship between loss of parts of the pinna in rabbits and rabbit haemorrhagic disease (MD).A case-control study design was employed. Rabbits with ear lesions were shot on farms in various locations in the South Island of New Z

An apparatus is described which is simply constructed and will measure anisotropy fields in small (mm) spheres or discs of single crystal material, at frequencies in the range 2 Hz to 50 kHz. At these frequencies and at readily accessible temperature

Bitter pattern observations were used to investigate the relationship between the applied field and wall velocity in a polycrystalline manganese-magnesium ferrite. The wall velocity was found to lie in the range 500 to 1000 cm sec-1 (effective Oe)-1

The distortion of the (μ, T) curve induced by grinding is shown to be essentially the same in character as that induced by a uniaxial stress. This arises because the grinding process tends to `stretch' the surface, so that the surface is put in comp

Before advancing any theory concerning the `squareness' or switching characteristics of a `square loop' ferrite it is necessary to assume a model for the domain (or rotational) configuration. In an attempt to obtain a knowledge of this configuration

Using single crystal spheres of less than 1?5 mm diameter changes of anisotropy field of the order of 0?1 Oe may be determined; hence the induced anisotropy constants F and G. If necessary the measurement may be made in the presence of the very large

Minor hysteresis loops of magnetite were observed at room temperature. Immediately after demagnetization the loop was of the Rayleigh type, but changed with time, while a small alternating field was present into a very rectangular loop which disappea
