  1. The effect of particle-size distribution on the suitability of sandy soils for sports fields

    The effect of particle-size distribution on the suitability of sandy soils for sports fields

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The compaction of the topsoil layer of sports fields can modify soil properties such as permeability, resistance to root penetration, aeration and water-holding capacity. The feasibility of predicting these properties from particle size distribution parameters of sandy soils was investigated...
  2. On group orders of rational points of elliptic curves

    On group orders of rational points of elliptic curves

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We consider elliptic curves without complex multiplication defined over the rationals or with complex multiplication defined over the Hilbert class field of the endomorphism ring. We examine the distribution of almost prime group orders of these curves when reduced modulo...
  3. Life form and species diversity on abandoned croplands, Roggeveld, South Africa

    Life form and species diversity on abandoned croplands, Roggeveld, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    The Roggeveld consists of an island of Mountain Renosterveld (Fynbos biome) surrounded by Succulent Karoo biome vegetation. Since management of abandoned croplands depends on a better understanding of their succession sequences, vegetation recovery on abandoned croplands in the Roggeveld was...
  4. Fostering Self-Determination and Resilience Through Sports Counselling: Psychosocial Development of Youth in Botswana

    Fostering Self-Determination and Resilience Through Sports Counselling: Psychosocial Development of Youth in Botswana

    Item type: Journal Article • Journal: Journal of Psychology in Africa
    Sports can promote pro-social behaviors and confidence in physical abilities among participants. We conducted an extensive review of the literature on the ways in which youth in Southern African countries, severely affected by the HIV/AIDS pandemic and other hardships may...
  5. On the way to Frölicher Lie groups

    On the way to Frölicher Lie groups

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we start by showing that one can obtain by way of diffeomorphisms some classical smooth curves and surfaces. The notion of bundles is also introduced in the category of Frölicher spaces, and one may carry on investigating...
  6. On Frobenius, Mazur, and Gelfand-Mazur theorems on division algebras

    On Frobenius, Mazur, and Gelfand-Mazur theorems on division algebras

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    The main purpose of this paper is to introduce the reader to the theory of normed division algebras. It is written with a graduate student of mathematics in mind, who only had exposure to Advanced Calculus and to an introduction...
  7. A narrative review of research on the effects of physical activity on people living with HIV and opportunities for health promotion in disadvantaged settings

    A narrative review of research on the effects of physical activity on people living with HIV and opportunities for health promotion in disadvantaged settings

    Item type: Journal Article • Journal: African Journal of AIDS Research
    The article explores different types and effects of physical activity for people living with HIV. Considering the lack of studies done in African contexts and the disparity between research settings and natural settings, a narrative review of the literature was...
  8. On evaluating multivariate polynomials over finite fields

    On evaluating multivariate polynomials over finite fields

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Some evaluation methods of multivariate polynomials over finite fields are described and their multiplicative complexity is discussed.
  9. Sports injuries in adults: overview of clinical examination and management

    Sports injuries in adults: overview of clinical examination and management

    Item type: Journal Article • Journal: South African Family Practice
    A wide variety of anatomical structures can be involved in a sports injury. To return to play as soon as possible is of utmost importance to an athlete, and in order to achieve this, a correct, all-inclusive diagnosis, a well-focused...
  10. Assessing the potential benefits of organic and mineral fertiliser combinations on legume productivity under smallholder management in Zimbabwe

    Assessing the potential benefits of organic and mineral fertiliser combinations on legume productivity under smallholder management in Zimbabwe

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Productivity of grain legumes on sandy soils of southern Africa is critically limited by marginal fertilisation. Effects of co-applying phosphorus (P)-based mineral fertilisers and organic nutrient resources to cowpea (Vigna unguiculata (L.) Walp.) and soyabean (Glycine max L.) were investigated...
