(North-West University (South Africa), 2019)The effectiveness and efficiency of small-scale farmers' agricultural production as a means of improving rural livelihood hinges on their access to timely and adequate agricultural information. The study focused on the ...Evaluation of soil to plant transfer factors of naturally occurring radioactive materials (norms) in some vegetables
(North-West University, 2012)Evaluation of specific genotypes in the context of the type 2 diabetes risk phenotype in the black South African population
(North-West University, 2010)Type 2 diabetes (T2D) is a complex disease that affects 4% of the general population and is expected to increase to 5.4% by the year 2025. A clear understanding of the aetiology of T2D susceptibility and pathogenesis ...Evaluation of the applicability of diatom based indices as bioindicators of water quality in South African rivers
(North-West University, 2008)Diatoms have been proven to be reliable indicators of water quality in many countries of the world particularly Europe. The potential use of diatoms as indicators of water quality in South Africa was tested in the studies ...Evaluation of the effect of selected plant growth regulators on soybean yield parameters in South Africa
(North-West University (South Africa), 2020)Soybean is an important protein and oilseed crop throughout the world due to the commercial use of soybean meal, oil and sub-products. South Africa is the largest soybean producer in Africa and produces on average 1.8 t ...Evaluation of the effects of coenzyme Q10 and succinate in a rotenone-induced complex I deficient rat model
(North-West University, 2006)Disorders of the mitochondrial respiratory chain have an incidence ranging from 1 in 2,000 to 1 in 5,000, with the most frequent of these cytopathies resulting from causative alterations within mitochondrial complex I, the ...Evaluation of the efficiency of magnets in deflecting Ag-atoms in the PBmr-Magnetic Isotope (MIS)
(North-West University (South Africa), 2008)The South-African Pebble Bed Modular Reactor (PBMR) is a high temperature gas cooled reactor (HTGCR) which uses the inert gas helium as a coolant and coated particles as fuel. The design of these coated particles is such ...The evaluation of the establishment and growth of indigenous trees to restore deforested riparian areas in the Mapungubwe National Park, South Africa
(North-West University, 2007)The deforestation of riparian areas is a major concern in southern Africa. These areas are characterized as fragile ecosystems which contribute largely to the regional and global biodiversity of the world. It is therefore ...An evaluation of the germination and establishment of three selected coated grass species in different soil types for rehabilitation
(North-West University, 2011)The primary impacts of mining on the environment include the deterioration of soil properties and the loss of vegetation cover and density, often leading to increased erosion. In order to encumber further degeneration ...An evaluation of the impact of land redistribution for agricultural development projects on beneficiaries in the Ngaka Modiri Molema district of North West Province, South Africa
(2011)The fundamental objective of this study was to evaluate the impact of the LRAD projects in the Ngaka Modiri Molema district of the North-West Province. Under the ownerships of LRAD beneficiaries, the majority of the projects ...Evaluation of the inorganic water chemistry of the Vaal River
