  1. Yields of Green Grams and Pigeonpeas under Smallholder Conditions in Machakos County, Kenya

    Yields of Green Grams and Pigeonpeas under Smallholder Conditions in Machakos County, Kenya

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    Green grams and pigeonpeas have multiple benefits to the rural poor as food security, fodder for livestock and fuel for small-scale farmers, despite low smallholder yields in Kenya. However, little is known about the factors between different farmers that influence...
  2. Assessment of Differences in Small Farmer Uses of Produce and Determinants of Marketed Surplus of Green Grams and Pigeon Peas in Semi-arid Machakos County, Kenya

    Assessment of Differences in Small Farmer Uses of Produce and Determinants of Marketed Surplus of Green Grams and Pigeon Peas in Semi-arid Machakos County, Kenya

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    Small farmers in semi-arid areas of eastern Kenya produce green grams and pigeon peas for both subsistence and income. Because of this, it was important for a detailed investigation on the difficulty of raising marketed surplus (produce) of green grams...
  3. Functional Diversity and Performance of Direct Marketing Outlets for Smallholder Farmers of Green Gram and Pigeon Pea Commodities in Machakos County, Kenya

    Functional Diversity and Performance of Direct Marketing Outlets for Smallholder Farmers of Green Gram and Pigeon Pea Commodities in Machakos County, Kenya

    Item type: Journal Article • Journal: East African Agricultural and Forestry Journal
    The smallholder direct marketing outlets (private grain traders) serve the smallholder farmers poorly in the rural areas of Kenya, making local markets thin and less competitive. The purpose of this study is to evaluate the diversity and the determinant factors...
  4. On symmetric <em>f</em>-biderivations of lattices

    On symmetric <em>f</em>-biderivations of lattices

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we introduce the notion of symmetric f-biderivation on lattices and investigate some related properties.
  5. On generalized (<em>α</em>, <em>β</em>)-derivations on lattices

    On generalized (<em>α</em>, <em>β</em>)-derivations on lattices

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper we introduce the notion of a generalized (α, β, d)-derivation on a lattice, with associated two sided α-derivation d, and investigate some related results. Among some other results we prove that “Let be a modular lattice...
  6. On the metric dimension of generalized Petersen graphs

    On the metric dimension of generalized Petersen graphs

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    A family G of connected graphs is said to be a family with constant metric dimension if its metric dimension is finite and does not depend upon the choice of G in G. In this paper, we study the metric...
  7. Correlation between spinal column length and the spread of subarachnoid hyperbaric bupivacaine in the term parturient

    Correlation between spinal column length and the spread of subarachnoid hyperbaric bupivacaine in the term parturient

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: Anaesthetists frequently tailor the subarachnoid local anaesthetic dosage according to parturient height to achieve sensory blockade up to the T4 dermatome for lower segment Caesarean sections (LSCSs). Studies that have been conducted have demonstrated that height does not affect...
  8. The response of theatre personnel to the pulse oximeter alarm

    The response of theatre personnel to the pulse oximeter alarm

    Item type: Journal Article • Journal: Southern African Journal of Anaesthesia and Analgesia
    Background: False alarms and sounds in the operating theatre (OT) that alert personnel to a crisis can be irritating. This can result in personnel ignoring genuine alarm warnings. This study was carried out to determine how alert OT personnel are...
  9. A new screening method for <em>Ganoderma philippii</em> tolerance in tropical <em>Acacia</em> species

    A new screening method for <em>Ganoderma philippii</em> tolerance in tropical <em>Acacia</em> species

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Red root rot disease caused by Ganoderma philippii is one of the most economically important diseases of tropical Acacia species. Research on field control of the disease has to date focused on inoculum reduction, silviculture practices and application of biological...
