Analysis of reference ranges of total serum protein in Namibia: clinical implications
(MDPI, 2020)A reference range is an essential part of clinical laboratory test interpretation and patient care. The levels of total serum protein (TSP) are measured in sera to assess nutritional, liver, and kidney disorders. This ... -
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ... -
Analysis of the post-earnings announcement drift anomaly on the JSE
(Taylor & Francis, 2013)The post-earnings announcement drift anomaly has been widely researched and confirmed for several markets around the world. This paper investigates the relationship between the earnings surprise as reflected by the price ... -
The Analysis of the Sepedi-English Code-switched Radio News Corpus
(UP Jornals, 2022)Code-switching is a phenomenon that occurs mostly in multilingual countries where multilingual speakers often switch between languages in their conversations. The unavailability of largescale code-switched corpora ... -
An analysis of the slow compression breakage of coal using microfocus X-ray computed tomography
(Taylor & Francis, 2015)The degradation of coal and the production of coal fines during handling and transport is a serious problem in processes that depend on closely sized large particles. To minimize the production of fines, a fundamental ... -
The analysis of voltage and current unbalance by application of active and reactive power in the fundamental frequency negative-sequence components
(IEEE, 2012)The behaviour of the fundamental frequency negative-sequence power components in unbalanced power networks is evaluated for possible information on the relative contribution by the supply and loading network. Previous ... -
Analysis of waveforms in modern power systems
(Wiley, 2008)This chapter contains sections titled: Frequency Analysis of Non-Sinusoidal Waveforms: Practical Considerations; Analog-to-Digital Conversion; Sequence Component Analysis; IEEE 1459: Power Definitions for modern Power ... -
The applicability of an existing fluted tube condenser model when used with refrigerant R-407C
(Elsevier, 2013)Fluted tube-in-tube condensers are key components in energy efficient water heating heat pumps. Rousseau et al. (2003) developed a model that incorporates all the essential features of these heat exchangers. A feature ... -
Application of data analytics to transport corridor diagnostics and performance benchmarking
(IEEE, 2018)Increase in exports is essential for economic growth in developing countries. In Southern Africa the development of effective multi-national trade corridors is the single biggest stumbling block to achieve this objective. ... -
Application of exergy-based fault detection in a gas-to-liquids process plant
(MDPI, 2019)Fault detection and isolation (FDI) within the petrochemical industries (PCIs) is largely dominated by statistical techniques. Although a signal-based technique centered on exergy flows within a process plant was proposed, ... -
Application of membrane technology in a base metal refinery
(SAIMM, 2013)Nanofiltration (NF) has attracted much attention over the past few years due to the reduced energy consumption compared to reverse osmosis (RO) and better separation performance compared to ultrafiltration (UF). Although ... -
The application of modern technology in power quality management
(IEEE, 2009)Little business integration of power quality management (PQM) is forthcoming amongst electrical utilities all over Southern Africa. Restricted access to proper information is the main reason. A integration of tools, ... -
Application of nanoparticles in biofuels: an overview
(Elsevier, 2019)Biofuels are fast advancing as alternative sources of renewable energy due to their non-polluting features and cost-competitiveness in comparison to fossil fuels. However, in order to fast-track their development, focus ... -
The application of system CFD to the design and optimization of high-temperature gas-cooled nuclear power plants
(ASME, 2008)The objective of this paper is to model the steady-state and dynamic operation of a pebble-bed-type high temperature gas-cooled reactor power plant using a system computational fluid dynamics (CFD) approach. System CFD ... -
Applications of additive manufacturing at selected South African universities: promoting additive manufacturing education
(Emerald, 2019)Purpose This paper aims to provide a comprehensive overview of the recent applications of additive manufacturing (AM) research and activities within selected universities in the Republic of South Africa (SA). Design/ ... -
Applying spontaneous adiabatic test procedure to determine CO2 gasification reactivity and kinetics of coal for UCG applications
(PCC, 2018)UCG is a gasification process used to produce synthesis gas from coal in situ (underground in the coal seam) by injecting air or oxygen, with or without steam, into coal seams and extracting the product gas via the ... -
Applying systems thinking in shaping South Africa's electricity system
(Wiley, 2014)The paper analyses the current situation in respect of South Africa's electricity situation and asks the question if Systems Thinking, more specifically as it pertains to the theory of Complex Adaptive Systems, would make ... -
An approach to improve the match-on-card fingerprint authentication system security
(IEEE, 2016)The combination of smart cards and biometrics results in a strong 2-factor authentication. It facilitates a trusted credential for authenticating an individual's identity through one-to-one biometric verification using the ... -
Aqueous solubility of Cr(VI) compounds in ferrochrome bag filter dust and the implications thereof
(WRC, 2017)The production of ferrochrome (FeCr) is a reducing process. However, it is impossible to completely exclude oxygen from all of the high-temperature production process steps, which may lead to unintentional formation of ...
