Enteric methane emissions and protozoa populations in Holstein steers fed spent mushroom (Flammulina velutipes) substrate silage-based diets
(Elsevier, 2017)Direct modification of rumen microbial fermentation could provide universal and cost-effective solutions to reduce methane emissions from ruminant livestock. In this study, the effect of feeding spent mushroom (golden ... -
Entomopathogenic nematodes for insect control, distribution and applicability in South Africa
(Egyptian Society for Biological Control of Pests (ESBCP), 2016)Entomopathogenic nematodes (EPNs) have long been recognized as pathogens that are killers of soil-dwelling insects. They are found in a variety of soil habitats where other nematodes such as; free-living, predaceous and/or ... -
Entrepreneurial orientation of sport coaches in Gauteng Province, South Africa
(LAM Publications; AJOL; Sabinet, 2013)There is general consensus among entrepreneurship scholars that entrepreneurial orientation is associated with entrepreneurial activity. However, it is equally acknowledged that entrepreneurial processes are a consequence ... -
Envelope bright- and dark-soliton solutions for the Gerdjikov Ivanov model
(Springer, 2015)Within the context of the Madelung fluid description, investigation has been carried out on the connection between the envelope soliton-like solutions of a wide family of nonlinear Schrödinger equations and the soliton-like ... -
Environment-related factors influencing morbidity among economically active household members in urban and rural Nigeria
(Business Perspectives, 2015)Environmental quality is among the factors influencing people’s health. In this paper, attempt was made to analyze environment-related factors that influence reported morbidity in Nigeria. During 2013 the Demographic and ... -
Environmental impact assessment and strategic environmental assessment in the UK after leaving the European Union
(Taylor & Francis, 2016)The United Kingdom has voted to leave the European Union and, until the terms of the ‘Brexit’ are negotiated, this has led to considerable uncertainty over the future practice of environmental impact assessment (EIA) and ... -
Environmental management frameworks: results and inferences of report quality performance in South Africa
(Taylor & Francis, 2015)Environmental management frameworks (EMFs) were developed in South Africa as strategic environmental management instruments to map environmental sensitivity in order to aid the screening out of undesired developments and ... -
Environmental pollutants and diseases of sexual development in humans and wildlife in South Africa: harbingers of impact on overall health?
(Wiley, 2012)This study deals with disorders of sexual development in humans, wildlife and animals in an urban nature reserve (RNR) and a currently DDT-sprayed malarial area. High levels of oestrogenic chemical residues in water, ... -
Environmental regulatory awareness of freshwater recreational bank anglers in South Africa
(2022)Freshwater recreational angling is growing in popularity internationally. Due to the potential negative environmental impacts, various regulatory systems exist. In South Africa, freshwater recreational angling is regulated ... -
Enzymatic characterization and elucidation of the catalytic mechanism of a recombinant Bovine Glycine N-Acyltransferase
(ASPET, 2012)Glycine conjugation, a phase II detoxification process, is catalyzed by glycine N-acyltransferase (GLYAT; E.C. 2.3.1.13). GLYAT detoxifies various xenobiotics, such as benzoic acid, and endogenous organic acids, such as ... -
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 ... -
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 ... -
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 ...
