On Compositeness in Multicompositions
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Temba ShonhiwaThe paper investigates the structure of the highly composite multicomposition function gm (n) which enumerates the number of m-compositions of n into relatively prime positive summands. Among other results, we generalize a known result by establishing that the lcm -
South African indigenous fruits – Underutilized resource for boosting daily antioxidant intake among local indigent populations?
Item type: Journal Article • Journal: South African Journal of Clinical Nutrition • Authors: Daniela Amalia Kucich --- Department of Chemistry, South Africa Merrill Margaret Wicht --- Department of Chemistry, South AfricaConsuming more than seven portions of fruit and vegetables daily substantially lowers the risk of mortality from any cause, yet many South Africans living below the poverty line have a very low or even zero intake of fruit and vegetables... -
Investigation of the properties and production of sawdust ceiling tile using polystyrene as a binder
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Pius Bamidele Mogaji --- Department of Mechanical Engineering, Nigeria Sesan Peter Ayodeji --- Department of Mechanical Engineering, Nigeria Ayodeji David Olatise --- Department of Mechanical Engineering, Nigeria Isiaka Oluwole Oladele --- Department of Material and Metallurgical Engineering, NigeriaIn this research, a production and properties investigation of wood sawdust ceiling tile using polystyrene as a binder was carried out. The content by weight of the wood sawdust was 5, 10, 15, 20, 25 and 30% consisting of three... -
Functionally graded metal matrix composite by centrifugal casting technique mathematical correlation
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Williams S. Ebhota --- Discipline of Mechanical Engineering, South Africa Freddie L. Inambao --- Discipline of Mechanical Engineering, South AfricaThe functionally graded materials (FGMs) solidification process has complicated movement phenomena of fluid, solute and heat. These phenomena control the segregation of particles in a molten matrix, interactions of particles with a solidification front and the integration of particles in... -
Estimated burden of aggregate anthropometric failure among Malawian children
Item type: Journal Article • Journal: South African Journal of Clinical Nutrition • Authors: M Ziba --- Faculty of Food and Human Sciences, Malawi AA Kalimbira --- Faculty of Food and Human Sciences, Malawi Z Kalumikiza --- Faculty of Food and Human Sciences, MalawiBackground: The prevalence and trends of undernutrition among children below the age of five in Malawi are well known from a conventional (stunting, wasting and underweight) but not aggregate indicator perspective. -
Flexural, water absorption and wear responses of green composites from bio-resources
Item type: Journal Article • Journal: African Journal of Science, Technology, Innovation and Development • Authors: Isiaka Oluwole Oladele --- Department of Metallurgical and Materials Engineering, Nigeria Oluwaseun Olayinka Abegunde --- Department of Metallurgical and Materials Engineering, Nigeria Abdullahi Olawale Masud --- Department of Metallurgical and Materials Engineering, NigeriaThis research was carried out to produce corn husk fibre reinforced recycled waste paper-based composites using natural rubber as a binder. The paper pulp was obtained by soaking waste paper in water for 24 hours after which it was ground...
