Evaluation and comparison of magnesium stearate and sodium stearyl fumarate (Pruv) as lubricants in directly compressible tablet formulations : their effect on tablet properties and drug dissolution
(North-West University, 2003)The most widely used lubricant in the pharmaceutical industry is probably magnesium stearate. Magnesium stearate exhibits its lubricating properties by forming a film of low shear strength between the die wall and the ... -
Evaluation and comparison of the physical properties and drug release characteristics of directly compressible lactose–based filler/binders
(North-West University, 2010)Direct compression has gained significant interest since its advent in the late 1950's due to its potential ease compared to wet granulation. The primary prerequisites for powders used in direct compression are (i) good ... -
The evaluation and comparison of various tablet disintegrants
(North-West University, 2008)The aim of the tablet formulator is to formulate a tablet, which when ingested, disintegrates to give the same system or powder blend as before compression. The faster this disintegration can occur, the faster the absorption ... -
Evaluation and implementation of DSM strategies to improve the profitability of marginal cement grinding plants
(North-West University (South Africa) , Potchefstroom Campus, 2015)The cement industry in South Africa is becoming increasingly competitive. Established cement producers have old inefficient production plants that have to compete with new cement producers abroad. These new cement companies ... -
Evaluation and management of diabetic patients in a primary healthcare clinic
(North-West University, 2007)In many African countries, including South Africa, much attention has been centred on the management of HIV/AIDS and tuberculosis epidemics. However, there is growing awareness in South Africa that life-style related ... -
Evaluation and modelling of particle collection efficiency of electrostatic precipitation
(North-West University (South Africa)., 2023)Many South-African power plants use wire-plate electrostatic precipitators (ESPs); however, these ESPs, in practice, have yet to meet the expected high particle collection efficiencies and present relatively low collection ... -
Evaluation and optimization of synthetic routes from dihydroartemisinin to the alkylamino-artemisinins artemiside and artemisone: a test of N-glycosylation methodologies on a lipophilic peroxide
(Elsevier, 2018)10-Alkylamino-artemisinins including artemiside and artemisone display enhanced activities against malaria. Earlier, dihydroartemisinin (DHA) TMS ether was converted by trimethylsilyl bromide into the 10-β-bromide that ... -
Evaluation and prediction of slow pyrolysis products derived from coals of different rank
(Elsevier, 2017)When coal is heated slowly (<10 °C/min), as in the Lurgi Fixed Bed Dry Bottom (FBDB) gasification process, products formed in the pyrolysis region of the gasifier include gas liquor, condensable tar, oil and non-condensable ... -
The evaluation and promotion of best practices for the restoration of arid- and semi-arid rangelands in southern Africa
(North-West University, 2007)Land degradation and desertification are threatening the livelihoods of millions of people all over the world, especially those living in sub-Saharan Africa. The problem is mainly ascribed to climatic factors, exacerbated ... -
The evaluation and quantification of respirable coal and silica dust concentrations : a task–based approach
(North-West University, 2009)Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts that contain crystalline silica. Silica exposure is ... -
The evaluation and quantification of respirable coal and silica dust concentrations: a task-based approach
(Taylor & Francis, 2014)Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts containing crystalline silica. The purpose of this ... -
Evaluation and redesign of radiation shielding in a radionuclide production facility at a particle accelerator
(2004)iThemba LABS is a particle accelerator facility housing a radionuclide production facility that uses a 66 MeV proton beam to produce radionuclides for medical and industrial use. Ionising radiation is produced by a variety ... -

Evaluation and validation of in vitro assays to determine cell viability for HIV/AIDS expermentation with Pheroid TM technology
(North-West University, 2008)The Southern parts of Africa have the highest prevalence of HIV-infected people and South Africa is the country with the highest number of infections in the world. There is still no cure for AIDS, but anti-HIV medicine can ... -
Evaluation and validation of methods to determine parasitemia in malaria cell cultures
(North-West University, 2008)The success in the treatment of malaria is dependent on the prompt and accurate diagnosis of malaria and effectiveness of the drug regime used. The emerging of resistance to most antimalarial drug makes the treatment of ... -
Evaluation and verification of an architecture suitable for a multi-unit control room of a pebble bed high temperature reactor nuclear power plant
(2015)Current regulations specify the minimum number of operators required per nuclear power plant. However, these requirements are based on the operation of large nuclear power plants, which are not inherent safe and can result ... -
Evaluation and verification of resistance in selected vegetable crops for sustainable root-knot nematode management in developing agriculture
(North-West University, 2006)Root-knot nematodes, (Meloidogyne species) are a major constraint in vegetable production systems. These parasites cause high yield losses, particularly in subsistence farming systems. This study was conducted to establish ... -
The evaluation framework for land restitution programme in the Northern Cape Province
