  1. Yield components of samples of two wild Mexican common bean (<em>Phaseolus vulgaris</em> L.) populations grown under cultivation

    Yield components of samples of two wild Mexican common bean (<em>Phaseolus vulgaris</em> L.) populations grown under cultivation

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The common bean (Phaseolus vulgaris L.) is an annual crop legume with wild ancestors distributed from Mexico to northern Argentina. In Mexico, wild populations occur throughout this physiographically and climatically diverse country. Such a wide distribution of common bean populations...
  2. Gorenstein injective envelopes and covers over <em>n</em>-perfect rings

    Gorenstein injective envelopes and covers over <em>n</em>-perfect rings

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We prove the existence of Gorenstein injective envelopes and covers over n-perfect rings for some classes of modules associated with a dualizing bimodule.
  3. ON A NEW PROOF OF DURIER'S THEOREM

    ON A NEW PROOF OF DURIER'S THEOREM

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A new proof of Durier's Theorem [3] concerning a characterization of Hilbert spaces in terms of the Fermat-Weber location problem will be presented.
  4. Headhood in Yorùbá nominal compounds

    Headhood in Yorùbá nominal compounds

    Item type: Journal Article • Journal: South African Journal of African Languages
    The lexical status of a class of composite words known as the nominal compounds in Yorùbá, is the focus of this article. The different semantic relations associated with the constituents of Yorùbá compounds as well as their varying deep structures...
  5. GRADED MATLIS DUALITY AND APPLICATIONS TO COVERS

    GRADED MATLIS DUALITY AND APPLICATIONS TO COVERS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We study homological properties of graded Matlis duality and apply them to get covers by Gorenstein gr-projective modules. We show that these covers are minimal graded maximal Cohen-Macaulay approximations in some cases.
  6. The seasonal intrusion of relatively saline water on the shelf off northern and central Namibia

    The seasonal intrusion of relatively saline water on the shelf off northern and central Namibia

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The movement of tropical, saline water onto the northern and central Namibian shelf in late summer and early autumn in the periods 1973–1974 and 1979–1986 is investigated. The strong intrusions in 1974, 1979, 1980(?), 1984 and 1986 appear related to...
  7. Influence of environmental conditions on the distribution of <em>Pterygosquilla armata capensis</em> (Crustacea: Stomatopoda) off Namibia

    Influence of environmental conditions on the distribution of <em>Pterygosquilla armata capensis</em> (Crustacea: Stomatopoda) off Namibia

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The distribution patterns of the benthic stomatopod crustacean Pterygosquilla armata capensis were studied off southern Namibia between latitudes 23 and 30°S and between about 50 and 500 m depth. Whereas south of 28°S and off the South African coast this...
  8. Relationship between measurements of hake biomass and sea surface temperature off southern Namibia

    Relationship between measurements of hake biomass and sea surface temperature off southern Namibia

    Item type: Journal Article • Journal: South African Journal of Marine Science
    A good relationship between the variability in measurements of Cape hake Merluccius capensis biomass during winter and summer swept-area research surveys and sea surface temperature off southern Namibia for the years 1983–1990 is presented. The results call into question the...
  9. Note on the diet of <em>Lithodes ferox</em> (Anomura: Lithodidae) off Namibia

    Note on the diet of <em>Lithodes ferox</em> (Anomura: Lithodidae) off Namibia

    Item type: Journal Article • Journal: South African Journal of Marine Science
    The diet of the deep-water anomuran crab Lithodes ferox was studied from samples taken by trawling off Namibia at depths of around 400 m. Analysis of foregut fullness revealed that feeding frequency was rather low: only 30,3% of the crabs...
  10. Modification of the electron transport system (ETS) method for routine measurements of respiratory rates of zooplankton

    Modification of the electron transport system (ETS) method for routine measurements of respiratory rates of zooplankton

    Item type: Journal Article • Journal: South African Journal of Marine Science
    Respiratory Electron Transport System activity (ETS) was determined in cell-free homogenates of mesozooplankton samples. Several assays were run to investigate possible improvements to the ETS method and to reduce sample processing time. The results showed that: (i) liquid nitrogen is...
