Enzymatic recovery of water from water hyacinth
(ETA-Florence Renewable Energies, 2013)This study sought to assess the viability of utilizing water recovered from a declared aquatic weed, Eichhornia crassipes, commonly known as the water hyacinth, for domestic, industrial and agricultural purposes. Celluclast, ... -
Ephesians: an ecclesiology of identity and responsibility in the light of God's cosmic plan and a canonical view of God's people
(Stellenbosch University, 2013)I show that God’s programme in history is to create for Himself1 a people to have a relationship with them. Yahweh will be their God and they will be His people. In this way God’s lordship becomes an experienced reality ... -
An epidemiological injury profile of South African youth soccer players
(Health and Medical Publishing Group, 2009)It is generally assumed that violent conflict has a negative effect on social capital, and war zones are considered to be 'zones of social capital deficiency'. This article challenges this position, and attempts to develop ... -
Epilythic cyanobacteria and algae in two geologically distinct caves in South Africa
(2019)There is a lack of knowledge on cyanobacteria and algae living in caves in the southern hemisphere. As a result, a pioneer study was undertaken to investigate cyanobacterial and algal community composition in two ... -
The epistemological implications of critical complexity thinking for operational research
(MDPI, 2019)Classical operational research (OR) is mainly concerned with the use of mathematical techniques and models used in decision-making situations. The basic assumptions of OR presuppose that the structure of the world is one ... -
The epistemology of Israelite religion : introductory proposals for a descriptive approach
(Department of Biblical and Ancient Studies University of South Africa, 2011)In this article I offer a venturesome introduction to the possibility of an analytic epistemology of Israelite religion. The aim is to propose some descriptive concerns for the biblical scholar interested in what the Hebrew ... -
Epizootic ulcerative syndrome – first report of evidence from South Africa's largest and premier conservation area, the Kruger National Park
(Elsevier, 2019)This study reports on the first evidence of genomic material of the causative agent for epizootic ulcerative syndrome (EUS), Aphanomyces invadans, from fish in the Limpopo River system and the Kruger National Park, South ... -
Equilibrium, kinetic, and thermodynamic studies of lead ion adsorption from mine wastewater onto MoS2-clinoptilolite composite
(Elsevier, 2020)This work explored the potential of clinoptilolite, molybdenum sulphide (MoS2), and MoS2-clinoptilolite composite in lead (Pb) removal from aqueous medium and industrial mining wastewater. MoS2-clinoptilolite composite was ... -
Equipping the poorest of the poor to become agents of community transformation: a case study of milk as a catalyst in Burundi
(AOSIS, 2017)Community transformation has cultural, political and religious dimensions. In the case of Burundi, it is ranked 188/188 on the scale of the world's poorest countries. The poor in Burundi have a fatalistic attitude towards ... -
Equity in South African Higher Education after apartheid
(IEEE, 2011)The apartheid regime in South Africa was a notable exception, as that regime explicitly opposed educational equality and openly discriminated against most of its citizens in all aspects of life. Equity efforts in the higher ... -
Equivalence after extension and matricial coupling coincide with Schur coupling, on separable Hilbert spaces
(Elsevier, 2013)It is known that two Banach space operators that are Schur coupled are also equivalent after extension, or equivalently, matricially coupled. The converse implication, that operators which are equivalent after extension ... -
Equivalence after extension and Schur coupling coincide for inessential operators
(Elsevier, 2018)In recent years the coincidence of the operator relations equivalence after extension (EAE) and Schur coupling (SC) was settled for the Hilbert space case. For Banach space operators, it is known that SC implies EAE, but ... -
Equivalence after extension and Schur coupling do not coincide on essentially incomparable Banach spaces
(London Mathematical Society, 2019)In 1994, H. Bart and V. É. Tsekanovskii posed the question whether the Banach space operator relations matricial coupling (MC), equivalence after extension (EAE) and Schur coupling (SC) coincide, leaving only the implication ... -
Equivalence after extension and Schur Coupling for relatively regular operators
(Springer, 2020)It was recently shown in Ter Horst et al. (Bull Lond Math Soc 51:1005–1014, 2019) that the Banach space operator relations Equivalence After Extension (EAE) and Schur Coupling (SC) do not coincide by characterizing these ... -
Equivalence after extension for compact operators on Banach spaces
(Elsevier, 2015)In recent years the coincidence of the operator relations equivalence after extension and Schur coupling was settled for the Hilbert space case, by showing that equivalence after extension implies equivalence after one-sided ... -
Equivalence of robust stabilization and robust performance via feedback
(Springer, 2009)One approach to robust control for linear plants with structured uncertainty as well as for linear parameter-varying plants (where the controller has on-line access to the varying plant parameters) is through linear-frac ... -
Equivalent electrical circuit modelling of a Proton Exchange Membrane electrolyser based on current interruption
(IEEE, 2013)A Proton Exchange Membrane (PEM) electrolyser is characterised and modelled to identify important electrochemical effects. These electrochemical effects include the ohmic, activation, and concentration losses within the ... -
Eradication of Bactrocera invadens (Diptera: Tephritidae) in Limpopo Province, South Africa
(Entomological Society of Soutern Africa, 2011)On 5 May 2010, Bactrocera invadens Drew, Tsuruta & White was detected in a methyl eugenol-baited surveillance trap in the northernmost part of the Limpopo Province in South Africa, an area adjacent to the Zimbabwe border. ... -
Ergonomic principles as an adjunct to the profession of biokinetics
(Sage, 2020)Work-related injuries date back to antiquity. Attempts to resolve these work-related challenges have, inter alia, led to the establishment of the professions of Ergonomics, Occupational Therapy, Physiotherapy, Occupational ...
