The determinants of under-five child mortality in the state of Palestine and Malawi: A comparative study
(University of the Western Cape, 2022)Mortality is one of the significant vital events for which a government collects data, especially child mortality, because it is one of the contributing indicators that are used to assess the wellbeing of a nation. ... -
Determinants of under-five mortality in South Africa: A logistic regression
(University of the Western Cape, 2019)While several interventions have been implemented over the past decade to combat child mortality, under-five mortality remains a challenge especially in Sub-Saharan Africa. Global-ly, child mortality has decreased to half ... -
Determinants of youth sexual behaviours and knowledge of reproductive tract infections (RTIs) and sexually transmitted infections (STIs) in Malawi : evidenced from the Demographic Health Survey 2010
(University of the Western Cape, 2015)The sexual behaviour of youths is believed to play a role in the spread of SexuallyTransmitted Infections (STIs) and Reproductive Tract Infections (RTIs). This study examinesthe determinants of youth sexual behaviours and ... -
The determination of boron using 11B(p, α)8Be nuclear reaction
(UWC, 2008)Determination of trace quantities of boron is required in various studies of materials and in geology. Using 11B(p, α)8Be nuclear reaction with focused proton beam of 670 keV energy is one of the few microanalytical ... -
Determination of Chromium(VI), Vanadium(V), Selenium(IV) and Zinc(II) in the City of Cape Town's potable water by stripping voltammetry at boron doped diamond electrodes
(University of the Western Cape, 2011)The main aim of this study is to investigate theelectrochemical determination of two beneficial (selenium and zinc) and two toxic (chromium and vanadium) metals in the potable water within the City of Cape Town's ... -
The determination of diffracted wave fields by an annulus according to Braunbek’s method
(University of the Western Cape, 1981)In this thesis a short wave approximation, the method oI W Braunbek, is used to determine the diffracted fields (acoustic and electromagnetic) of plane harmonic waves by an annular aperture. Integral representations ... -
The determination of excitation functions for natRb+p up to 100 MeV with an emphasis on the production of 82Sr
