  1. Engineering research profile of countries in the African Union

    Engineering research profile of countries in the African Union

    Scholarly publication output of engineering research from the member countries of the African Union (AU) are mapped using scholarly publication data from the Scopus® database of Elsevier. The countries are ranked based on various parameters, for example; number of publications,...
  2. Foreign R&D units in India and China: An empirical exploration

    Foreign R&D units in India and China: An empirical exploration

    Among the many corporate functions of multinational enterprises (MNEs), their foreign R&D is considered to be the least mobilized. Firms usually keep their crucial R&D activities close to their home base. However, since the 1990s MNEs from developing countries are...
  3. Science, technology and innovation in BRICS countries: Introduction to the special issue

    Science, technology and innovation in BRICS countries: Introduction to the special issue

    The BRICS (Brazil, Russia, India, China and South Africa) economies have been the subject of many scholarly studies in recent years, as well as featuring in the popular media. This special issue of the African Journal of Science, Technology, Innovation...
  4. Developing allometric equations for estimating leaf area and leaf biomass of <em>Artocarpus chaplasha</em> in Raghunandan Hill Reserve, Bangladesh

    Developing allometric equations for estimating leaf area and leaf biomass of <em>Artocarpus chaplasha</em> in Raghunandan Hill Reserve, Bangladesh

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Estimation of leaf area (LA) and leaf biomass (LB) is important to understand plant physiological and carbon assimilation processes, and tree growth models. The aim of this study was to develop and compare allometric equations for predicting LA and LB...
  5. ON THE TITCHMARSH-WEYL THEORY OF ORDINARY SYMMETRIC ODD-ORDER DIFFERENTIAL EXPRESSIONS AND A DIRECT CONVERGENCE THEOREM

    ON THE TITCHMARSH-WEYL THEORY OF ORDINARY SYMMETRIC ODD-ORDER DIFFERENTIAL EXPRESSIONS AND A DIRECT CONVERGENCE THEOREM

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper the odd-order differential equation M[y] λ wy on the interval (O,∞), associated with the symmetric differential expression M of (2k-1)st order (k ≥ 2) with w a positive weight function and λ a complex number, is shown...
  6. On two topologies associated with a topology

    On two topologies associated with a topology

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    With every topology T on a set X, two finer topologies on X have been introduced in the past, viz., the so-called front topology and the indiscrete generated refinement of T. It is shown here that these are nicely inter-related...
  7. A fixed point theorem in <em>G</em>-metric spaces via <em>α</em>-series

    A fixed point theorem in <em>G</em>-metric spaces via <em>α</em>-series

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In the context of G-metric spaces we prove a common fixed point theorem for a sequence of self mappings using a new concept of α-series.
  8. The 26 December 2004 Sumatra tsunami recorded on the coast of West Africa

    The 26 December 2004 Sumatra tsunami recorded on the coast of West Africa

    Item type: Journal Article • Journal: African Journal of Marine Science
    Analysis of sea-level data obtained from the Atlantic Global Sea Level Observing System (GLOSS) sea-level station at Takoradi, Ghana, West Africa, clearly reveals a tsunami signal associated with the Mw = 9.3 Sumatra earthquake of 26 December 2004 in the...
