Efficacy of fish- and hydramethylnon-based baits for conservation of the African weaver ant Oecophylla longinoda (Hymenoptera: Formicidae) during cashew off-seasons in Tanzania
(Cambridge Univ Press, 2015)The efficacy of fish- and hydramethylnon-based baits for conservation of the African weaver ant (AWA) Oecophylla longinoda Latreille was evaluated at orchards in Bagamoyo and Mkuranga districts, Coast region of Tanzania, ... -
The efficacy of protein supplementation during recovery from muscle-damaging concurrent exercise
(NRC Research Press, 2017)This study investigated the effect of protein supplementation on recovery following muscle-damaging exercise, which was induced with a concurrent exercise design. Twenty-four well-trained male cyclists were randomised to ... -
Efficacy of the African weaver ant Oecophylla longinoda (Hymenoptera: Formicidae) in the control of Helopeltis spp. (Hemiptera: Miridae) and Pseudotheraptus wayi (Hemiptera: Coreidae) in cashew crop in Tanzania
(Wiley, 2013)BACKGROUND:Cashew, Anacardiumoccidentale, is aneconomically important cash crop formorethan 300 000 rural households in Tanzania. Its production is, however, severely constrained by infestation by sap-sucking insects such ... -
Efficiency behaviour of kernel-smoothed kernel distribution function estimators
(SASA, 2020)The asymptotic mean integrated squared error (AMISE) and the kernel efficiency (KE) of kernel distribution function estimators are well studied. In this note we define new nonparametric distribution function estimators by ... -
Efficient waste reduction algorithms based on alternative underestimates for the modified Wang method
(Operations Research Society of South Africa, 2014)This paper is concerned with wastage reduction in constrained two-dimensional guillotine- cut cutting stock problems, often called trim loss problems. A number of researchers report in the literature on algorithmic ... -
Efflux as a mechanism of antimicrobial drug resistance in clinical relevant microorganisms: the role of efflux inhibitors
(Taylor & Francis, 2017)Introduction: Microbial resistance against antibiotics is a serious threat to the effective treatment of infectious diseases. Several mechanisms exist through which microorganisms can develop resistance against antimicrobial ... -
Efflux pumps genes of clinical origin are related to those from fluconazole-resistant Candida albicans isolates from environmental water
(IWA Publishing, 2018)Efflux pumps coded for by CDR1, CDR2, FLU1 and MDR1 genes could be responsible for the observed resistant phenotypes in azole-resistant Candida albicans from environmental water. This was demonstrated for clinical isolates. ... -
Egg banks in dryland wetlands provide information on the diversity and vulnerability of branchiopod communities along a longitudinal aridity gradient
(2022)Continued degradation of temporary wet-lands and rapidly declining freshwater biodiversity call for identification of vulnerable species as targets for conservation and management efforts. Branchiopod crustaceans are ... -
Eigenvalue perturbation theory of symplectic, orthogonal, and unitary matrices under generic structured rank one perturbations
(Springer Verlag, 2014)We study the perturbation theory of structured matrices under structured rank one perturbations, with emphasis on matrices that are unitary, orthogonal, or symplectic with respect to an indefinite inner product. The rank ... -
Ekonometriese modelle in finansiële risiko
(AOSIS, 2008)This paper provides an overview of the contributions by prof JH Venter to financial risk and volatility modelling, estimation and forecasting. Venter's research is based on the classical GARCH model which he refines in ... -
Ekonomiese waarde van groen ruimtes: Suid-Afrika in kontras met Europa
(SUN MeDIA Bloemfontein, 2013)Die toenemende tempo van wêreldwye verstedeliking veroorsaak (onder andere) dat groen ruimtes verwaarloos word en soms opgeoffer word. Stedelike gebiede word hoër gewaardeer as groen ruimtes, omdat stedelike gebiede gemeet ... -
An elderly, urban population: their experiences and expectations of pharmaceutical services in community pharmacies
(AOSIS, 2017)Objective: The aim of this study was to determine the pharmaceutical services experiences of an elderly, urban population in relation to their expectations in community pharmacy. Design: and setting: The study was a ... -
Electrical resistivity of carbonaceous bed material at high temperature
(Springer Verlag, 2020)This study reports the effect of high-temperature treatment on the electrical properties of charcoal, coal, and coke. The electrical resistivity of industrial charcoal samples used as a reducing agent in electric arc ... -
Electrocatalytic oxidation of Epinephrine and Norepinephrine at metal oxide doped phthalocyanine/MWCNT composite sensor
(Nature Publishing Group, 2016)Glassy carbon electrode (GCE) was modified with metal oxides (MO?=?Fe3O4, ZnO) nanoparticles doped phthalocyanine (Pc) and functionalized MWCNTs, and the electrocatalytic properties were studied. Successful synthesis of ... -
An electrochemical and theoretical comparison of ionic transport through a polystyrene based titanium-vanadium (1:2) phosphate membrane
(Elsevier, 2011)Ionic potentials were measured across polystyrene based titanium–vanadium (1:2) phosphate membranes with 1:1 electrolytes at different concentrations. These observed values are found to compare well with membrane potentials ... -
