(North-West University (South Africa), 2019)
South Africa is one of the developing countries in the world which is dominated by rural areas. In such countries supplies of basic services such as water and sanitation facilities are a challenge. As a result, the available ...
Time–dependent modulation of cosmic rays in the outer heliosphere
(North-West University, 2013)
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied by computing
intensities using a two-dimensional, time-dependent modulation model. The compound
approach of Ferreira and Potgieter (2004), ...
Conservation assessment of threatened frogs in KwaZulu–Natal and a national assessment of chytrid infection in threatened South African species
(North-West University, 2012)
Amphibians are the most threatened Class of vertebrate on Earth, with 30% of all species IUCN Red Listed. This proportion is reflected in South Africa, where 29% of all species assessed in 2011 (SA-FRoG 2010; IUCN 2011; ...
Synthesis of selected cage alkenes and their attempted ring–opening metathesis polymerisation with well–defined ruthenium carbene catalysts
(North-West University, 2011)
In this study a number of cage alkenes were synthesised and tested for activity towards ringopening metathesis polymerisation (ROMP) with the commercially available catalysts 55 (Grubbs-I) and 56 (Grubbs-II). The first ...
A critical analysis of the application of S24G provisions of the National Environmental Management Act (NEMA) : the Gauteng Province experience
(North-West University, 2012)
Together with an internationally praised Constitution, South Africa can pride itself in
having one of the best sets of environmental laws in the world, and since EIAs have
become mandatory for projects that negatively ...
Whole genome characterisation and engineering of chimaeric rotavirus–like particles using African rotavirus field strains
(North-West University, 2012)
Despite the global licensure of two live-attenuated rotavirus vaccines, Rotarix® and RotaTeq®, rotavirus remains the major cause of severe dehydrating diarrhoea in young mammals and the need for further development of ...
The molecular basis of the genetic mosaicism in hereditary tyrosinemia (HT1)
(North-West University, 2011)
Hereditary tyrosinemia type 1 (HT1) is an autosomal recessive disorder of the tyrosine
degradation pathway. The defective fumarylacetoacetate hydrolase enzyme causes the accumulation of upstream metabolites such as ...
Metaobjects as a programming tool
(North-West University, 2010)
Computer applications can be described as largely rigid structures within which an
information seeker must navigate in search of information - each screen, each transaction having underlying unique code. The larger the ...
A comparison of integrated transport and spatial planning instruments : a case study of the Eden district municipality, Hermanus local municipality and Cape Town metropolitan areas
(North-West University, 2012)
In the field of city planning, a growing need exists for the integration of spatial development with transportation planning instruments. This study identifies issues related to the definition, evaluation and implementation ...
Construction of a mitochondrial consensus sequence for the Khoi-San population of Southern Africa
(North-West University, 2010)
The revised Cambridge Reference Sequence (rCRS) is used as a standard for the human mitochondrial DNA (mtDNA) sequence in studies of human evolution and the identification of disease-causing mutations. Due to the large ...
