The earliest reports of magnetically induced optical birefringence included data for liquids, magnetic fluids and colloidal suspensions. Recent work has shown that with relatively straightforward apparatus, when carefully designed and aligned, measur

The fundamental mechanism for magneto-rheological clutches, switches and devices is the ability of magnetic fields to induce relatively thick, linearly extended structures which span the relevant fluid medium. Recent observations have shown these to

Measurements have been made of the field strength and time dependence of the linear dichroism induced by magnetic fields in magnetite–based ferrofluid films. When combined with optical diffraction data, three characteristic regions, each indicative

Magnetic fields induce order and hence optical birefringence in suspensions of anisotropic, anisodiametric, and diamagnetic particles. Many colloids and latexes are sufficiently diamagnetic to exhibit this effect for relatively weak magnetic fields.

The purpose of the paper is to explain the linear birefringence and dichroism observed in magnetic fluids when subjected to a magnetic field. Linear aggregates of nanosize near spherical particles, which are considered to be responsible for these phe

The growth and decay rates of rapid, induced electro-optical phenomena in dilute colloidal suspensions are characteristic of the geometry of the solute particles. The speed of measurement renders such methods especially relevant for fast, in situ ana

Recent intensification of New Zealand dairy farms appears to be premised on both increased production and milksolid (MS) price covering the increased capital and running costs resulting from intensification. The present paper examined the effect of i

There is potential to increase the profitability of beef-breeding cows in New Zealand by calving heifers for the first time at 2 instead of 3 years of age; however, calving at this earlier age is often associated with an increase in assistance at cal
