Conservation of scattered energy and asymmetry factor in the new Rotationally Symmetric Spherical Discretisation scheme
(Elsevier, 2016)A Rotationally Symmetric Spherical Discretisation (RSSD) technique has recently been developed for the discretisation of scattering phase functions in the Discrete Ordinates Method (DOM) in a consistent and rational manner. ... -
A methodology to investigate the contribution of conduction and radiation heat transfer to the effective thermal conductivity of packed graphite pebble beds, including the wall effect
(Elsevier, 2017)The effective thermal conductivity represents the overall heat transfer characteristics of a packed bed of spheres and must be considered in the analysis and design of pebble bed gas-cooled reactors. During depressurized ... -
Optimization of counting time using count statistics on a diffraction beamline
(Elsevier, 2016)The feasibility of an alternative data acquisition strategy to improve the efficiency of beam time usage with neutron strain scanner instruments is demonstrated. By performing strain measurements against set statistical ... -
Tswana finite state tokenisation
(Springer, 2015)Tswana, a Bantu language in the Sotho group, is characterised by an agglutinative morphology and a disjunctive orthography, which mainly affects the verb category. In particular, verbal prefixes are usually written ... -
Exploring the effect of an asset management system on the efficiency and reliability of transformers in a power utility
(North-West University (South Africa) , Potchefstroom Campus, 2015)The research presents an analysis of Eskom’s transmission transformer performance in support of the company’s Asset Management System. Eskom Transmission is currently implementing an Asset Management approach to making ... -
Development and validation of portion size food photographs to determine maize intake of young children in rural Eastern Cape Province
(North-West University (South Africa) , Potchefstroom Campus, 2016)Objective: The objective of the study was to develop and validate a portion size food photograph series to more accurately determine maize intake of infants aged 6 - 24 months living in deep rural areas in the Eastern ... -
A method for the seasonal performance rating of a residential water heating heat pump
(North-West University (South Africa) , Potchefstroom Campus, 2015)To save electricity in the South African residential market, energy efficient air source water heating heat pumps have been widely implemented in combination with conventional hot water storage vessels, also known as ... -
Environmental impact assessment legislation in Lesotho, Swaziland and South Africa
(North-West University (South Africa) , Potchefstroom Campus, 2015)Due to the global endeavour to conserve the environment and to ensure that development is undertaken in a sustainable manner, mechanisms have been developed across the world to protect the environment during the process ... -
An assessment of the biodistribution, biopersistence and toxicity of gold nanoparticles
(North-West University (South Africa) , Potchefstroom Campus, 2015)The interest in biomedical applications of gold nanoparticles (AuNPs) has increased dramatically in the last decade due to their ease of synthesis, unique surface and optical properties. The main driver of this surge in ... -
Sample positioning in neutron diffraction experiments using a multi-material fiducial marker
(Elsevier, 2017)An alternative sample positioning method is reported for use in conjunction with sample positioning and experiment planning software systems deployed on some neutron diffraction strain scanners. In this approach, the ... -
The implementation of a retention policy in the Limpopo Provincial Treasury
(North-West University (South Africa) , Potchefstroom Campus, 2016)Retention Management is one of the major challenges impacting on service delivery in the Public Service. Retaining core employees in organisations is not always strategically prioritised, despite the cost of turnover to ... -
The potential impact of sustainable use of biodiversity resources on permanent sovereignty in SADC
(North-West University (South Africa) , Potchefstroom Campus, 2015)The principle of permanent sovereignty over natural resources (hereafter PSNR) gives states the authority to freely use and dispose, manage and exploit their natural resources, so as to benefit their citizens. On the other ... -
Factors influencing implementation strategies regarding environmental design in neonatal intensive care units
(North-West University (South Africa) , Potchefstroom Campus, 2015)Background Nurses working in neonatal intensive care units (NICUs) in South Africa’s public hospitals might be familiar with the guidelines regarding the optimal environment for preterm infant development. However, a ... -
Academic literacy of South African higher education level students: does vocabulary size matter?
(University of Stellenbosch, 2015)This study explores the extent to which vocabulary size matters in academic literacy. Participants (first-year students at North-West University) were administered the Vocabulary Levels Test (Schmitt, Schmitt and Clapham ... -
Challenges of testing deep word knowledge of vocabulary: which path to follow?
(South African Association for Language Teaching (SAALT), 2015)The present research explores the challenges of testing deep word knowledge of the vocabulary of students of English as a Foreign/ Second Language (EFL/ESL) at higher education. A productive test modelled on the Lex30 ... -
Occupational health and safety considerations for women employed in core mining positions
(AOSIS, 2015)Orientation: Despite various liberalisation and feminisation processes with regard to gender and sex roles, traditionalistic typologies, especially in terms of occupational roles, are seemingly very reluctant to disappear ... -
Measuring receptive collocational competence across proficiency levels
(University of Stellenbosch, 2015)The present study investigates (i) English as Foreign Language (EFL) learners’ receptive collocational knowledge growth in relation to their linguistic proficiency level; (ii) how much receptive collocational knowledge ... -
