A comprehensive quality management model for community newspapers
(North-West University, 2012)The quality of South African (and indeed global) journalism has been under close scrutiny for several years, resulting in criticism regarding issues such as a lack of depth, diversity and accuracy. A lack of effective ... -
Comprehensive rural development planning : an integrated approach
(2015)Since 1994, the main challenges of rural development in South Africa are related to fighting against the marginalization of the poor, which requires change in access to resources (i.e. land, water, education and skills), ... -
Comprehensive school–health services in selected secondary schools in the North West province
(2013)Adolescents who are subjected to adverse health risks which limit school attendance and academic performance, is a national as well as an international recognised problem considering healthy youth to be productive members ... -
The comprehensive strategic partnership agreement between South Africa and China : a geopolitical case study considering African realism (2010–2015)
(North-West University (South Africa)., 2019)Following the end of the Cold War and apartheid, both South Africa and China were rising politically and economically in a globalised multi-polar world order. South Africa rose to prominence after the first democratic ... -
A comprehensive stress testing model to evaluate systemic contagion and market illiquidity in banks
(2013)This dissertation presents a liquidity stress-testing model for evaluating liquidity and systemic risk in banks from developed and emerging economies respectively. The model further relies on simulations to generate ... -
A comprehensive study of air quality in urban, low-income areas of South Africa
(SASAS, 2014)Multi-year ambient air quality data from 4 networks (19 sites) in Gauteng have been analyzed, in addition to data from intensive indoor and outdoor air quality monitoring in a small township in Mpumalanga province. PM10 ... -
A compressed air cost savings identification model for deep-level mines
(North-West University (South Africa), 2019)Eskom has requested a 15% electricity tariff increase over the next three years, which will put an increased burden on the South African mining sector. The cost of electricity directly influences the profitability of the ... -
Compressed air energy savings on an iron production plant
(North-West University (South Africa) , Potchefstroom Campus, 2016)In the past several decades, energy efficiency has become increasingly important. A large driver behind this is reducing greenhouse gases that are caused by the combustion of fossil fuels. Most electricity generated in ... -
Compression garments and recovery from exercise-induced muscle damage: a meta-analysis
(BMJ Publishing Group, 2014)The purpose of the study was to determine the effects of compression garments on recovery following damaging exercise. A systematic review and meta-analysis was conducted using studies that evaluated the efficacy of ... -
Compression garments and recovery from exercise: a meta-analysis
(Springer, 2017)Background Adequate recovery from exercise is essential to maintain performance throughout training and competition. While compression garments (CG) have been demonstrated to accelerate recovery, the literature is clouded ... -
Compromised bioavailable IGF-1 of black men relates favourably to ambulatory blood pressure: the SABPA study
(Elsevier, 2014)Objectives Insulin-like growth factor-1 (IGF-1) has potent endothelial-protective, anti-platelet and anti-thrombotic activities, and also exerts mitogenic and proliferatory actions on vascular smooth muscle cells. Conflicting ... -
Computational chemistry study of zirconium monomers in low acid concentration aqueous solutions
(IOP Publishing, 2018)Zirconium and hafnium have to be separated prior to their use in nuclear energy reactors. Therefore, a lot of research has been done on the solvent extraction of zirconium. However, most of this research involved screening ... -
Computational cost of an exergy-based fault detection scheme implemented in a commercial process simulator
(Elsevier, 2019)Energy-based fault detection and isolation (FDI) schemes show promise in terms of applicability to petrochemical industries and the broader process industries. Model-based FDI schemes offer pronounced advantages over more ... -
Computational method based on bernstein operational matrices for multi-order fractional differential equations
(Univ Nis, 2014)In this paper, the Bernstein operational matrices are used to obtain solutions of multi-order fractional differential equations. In this regard we present a theorem which can reduce the nonlinear fractional differential ... -
Computational method for non-linear singular boundary value problems
(SASIP, 2017)This paper presents a new numerical approach based on the Chebyshev polynomials of the first kind for solving a class of nonlinear singular boundary value problems arising in physiology. We apply the quasilinearization ... -
Computational methods for the determination of roundness of sedimentary particles
(Springer, 2006)A number of subjective and objective methods have been proposed to determine the roundness of rock particles, roundness being one of three properties describing the shape of a particle. Methods that make use of the Fourier ... -
A computational model for the description of electrostatic precipitator performance
(North-West University, 2019)A comprehensive computational model of an electrostatic precipitator was developed by incorporating the interacting phenomenon of fluid dynamics, particle dynamics and electrostatics using the commercial software STAR-CCM+® ... -
Computational modelling and optimal control of Ebola virus disease with non-linear incidence rate
(IOP Publishing, 2017)The 2014 Ebola outbreak in West Africa has exposed the need to connect modellers and those with relevant data as pivotal to better understanding of how the disease spreads and quantifying the effects of possible interventions. ... -
