Measurement of soil in sugar cane using non-destructive techniques.
(2001)The soil being delivered with sugar cane consignments. from the cane fields to the factories, has been a recent cause for concern in the South African sugar industry. The soil impurities increase the wear of processing ... -
Measurement of the Kerr electro-optic effect by induced birefringence.
(2005)During the period January 2001 to January 2003, M Sc student Mr Tleyane Jonas Sono developed an apparatus to measure the pressure- and temperature-dependence of the electro-optic Kerr effect (electric-field-induced ... -
Measurement of the temperature dependence of the Buckingham effect (electric-field-gradient-induced birefringence) in gases
(2009)The aim of this research project was to assemble an apparatus to measure the electric quadrupole moments of gas molecules using the technique of electricfield- gradient-induced birefringence, or the Buckingham effect. ... -
