Cowpea yield under the influence of cropping system, location and nitrogen fertilization
(Agricultural Research Communication Centre, 2016)Yield production of cowpea depends largely on the environmental factors, cropping systems and soil type of the location. In this way, an experiment was conducted to investigate the interaction effect of cropping system, ... -
Cr(VI) and conductivity as Indicators of surface water pollution from ferrochrome production in South Africa: four case studies
(Springer, 2015)South Africa is one of the largest ferrochromium (FeCr) producers. Most FeCr is exported to developed countries. Therefore the impact of this industry is of national and international importance. Cr(VI) and conductivity ... -
Cr(VI) formation during ozonation of Cr-containing materials in aqueous suspension: implications for water treatment
(WRC, 2012)Ozonation, or advanced oxidation processes (utilising ozone decomposition products as oxidants) are widely used in industrial wastewater and drinking water treatment plants. In these applications the use of ozone is based ... -
Cr(VI) generation during flaring of CO-rich off-gas from closed ferrochromium submerged arc furnaces
(Springer, 2015)Ferrochromium (FeCr) is the only source of new Cr units used in stainless steel production, which is a vital modern day alloy, making FeCr equally important. Small amounts of Cr(VI) are unintentionally formed during several ... -
Cr(VI) generation during sample preparation of solid samples - a chromite ore case study
(WRC, 2010)South Africa holds more than 70% of the world's viable chromite ore reserves and produces ~46.2% of the world's high carbon ferrochrome. It was recently reported that beneficiated South African chromite ores contained ... -
A Crank-Nicolson finite difference approach on the numerical estimation of rebate barrier option prices
(Taylor & Francis, 2019)In modelling financial derivatives, the pricing of barrier options are complicated as a result of their path-dependency and discontinuous payoffs. In the case of rebate knock-out barrier options, discount factors known ... -
