    The ‘new’ bricks-and-mortar store: An evaluation of website quality of online grocery retailers in BRICS countries

    Background: Online grocery retailing holds potentially fruitful outcomes for retailers and consumers. However, both retailers and consumers have been slow to adopt and participate in this form of grocery retailing, especially in countries with emerging economies such as those in...
  2. Seasonal uptake and distribution of nutrient elements by kiwifruit vines 1. Macronutrients

    Seasonal uptake and distribution of nutrient elements by kiwifruit vines 1. Macronutrients

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Dry matter production and uptake and distribution of macronutrients in kiwifruit vines (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson var. deliciosa) cv. Hayward were studied in sand culture. The total dry mass of the kiwifruit vine increased sharply...

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Aspects of the demersal longline fishery in South Africa for kingklip and hake are described. Longline effort was distributed in five distinct regions in 1985 and a trend of increasing catch rate for kingklip was observed from the West Coast...
  6. A note on the length/mass relationship and mass conversion factors for Agulhas sole <em>Austroglossus pectoralis</em>

    A note on the length/mass relationship and mass conversion factors for Agulhas sole <em>Austroglossus pectoralis</em>

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The relationship between mass and length and the landed mass/whole mass conversion factors for Agulhas sole Austroglossus pectoralis were investigated and compared to the results of an earlier study. Earlier length/mass relationships overestimate the mass of small soles but underestimate...

  10. Die strukturering van kennis vir 'n skynintelligente rekenaarondersteunde taalonderrigprogram

    Die strukturering van kennis vir 'n skynintelligente rekenaarondersteunde taalonderrigprogram

    Item type: Journal Article • Journal: South African Journal of Linguistics
    Navorsing oor die aanwending van die rekenaar as hulpmiddel by taalonderrig het in die komplekse, veeltalige onderwyssituasie in Suid-Afrika dringend noodsaaklik geword. Die soepelheid en interaktiwiteit van rekenaarondersteunde onderrigprogramme kan verhoog word deur die toepassing van tegnieke van skynintelligensie. In...
