Magnesium intake predicts bone turnover in postmenopausal black South African women
(MDPI, 2019)This prospective study investigated the association between nutrient intake, dietary patterns, and changes in bone turnover and bone mineral density (BMD) in postmenopausal urban black South African women over two years. ... -
A numerical analysis of laminar boundary layer flow of a jeffrey fluid past a vertical porous plate in the presence of thermal radiation and chemical reaction
(Pushpa, 2019)This work deals with the study of the flow of a Jeffrey’s fluid past a vertical porous plate in the presence of thermal radiation and chemical reaction. A similarity transformation is used to transform the partial differential ... -
The predicting success factors of mobile applications development: organizational perspectives
(IADIS, 2019)Mobile applications (mobile apps) development is one of the fastest evolving technological innovations across the globe. The immense growth of mobile apps development can be attributed to the incredible rate of growth of ... -
The adoption of m-commerce applications: rural dwellers’s perspectives
(IADIS, 2019)In recent years, mobile applications (mobile apps) have gained widespread acceptance. Mobile apps services have effectively encircled most of the human activities, with the purpose of improving the living standard of the ... -
Simulating precipitation and temperature in the Lake Champlain basin using a regional climate model: limitations and uncertainties
(Springer, 2019)The Lake Champlain Basin has socioeconomic and ecological significance for the Northeastern United States and Quebec, Canada. Temperatures and extreme precipitation events have been increasing across this region over the ... -
Density-dependent growth response and sensitivity of Meloidogyne incognita to Maerua angolensis and Tabernaemontana elegans: Card model
(Taylor & Francis, 2019)Curve-fitting Allelochemical Response Dosage (CARD) computer-based model has proven to be a valuable tool in the definition of dosage response relationships between organisms and various plant extracts. Its use in the ... -
Exploring rain forest diversification using demographic model testing in the African foam‐nest treefrog Chiromantis rufescens
(Wiley, 2019)Aim Species with wide distributions spanning the African Guinean and Congolian rain forests are often composed of genetically distinct populations or cryptic species with geographic distributions that mirror the locations ... -
Evolution or revolution? Reflecting on IA effectiveness in Thailand
(Taylor & Francis, 2019)This paper investigates whether the Thai impact assessment (IA) system should develop through revolution or evolution. A timeline of the Thai IA system is mapped to show its development to date. Aspects of effectiveness ... -
Easterly wave contributions to seasonal rainfall over the tropical Americas in observations and a regional climate model
(Springer, 2019)Easterly waves (EWs) are important moisture carriers and their variability can impact the total May–November rainfall, defined as seasonal precipitation, over the Tropical Americas. The contribution of EWs to the seasonal ... -
Correction to the type locality of Tomopterna ahli (Deckert, 1938) (Anura: Pyxicephalidae), with the designation of a neotype
(Magnolia Press, 2019)Deckert described a Tomopterna as Arthroleptella ahli from South Africa in 1938. We demonstrate that the type of Tomopterna ahli (Deckert, 1938) was actually collected in Namibia, and that this nomen is a senior synonym ... -
Participatory rural appraisal approaches for public participation in EIA: lessons from South Africa
(MDPI, 2019)Public participation in environmental impact assessment (EIA) often falls short of the requirements of best practice in the move towards sustainable development, particularly for disadvantaged and marginalized communities. ... -
Waste plastic, the challenge facing developing countries - ban it, change it, collect it?
(MDPI, 2019)With changing consumption patterns, growing populations and increased urbanisation, developing countries face significant challenges with regards to waste management. Waste plastic is a particularly problematic one, with ... -
Understanding future changes in tropical cyclogenesis using Self-Organizing Maps
(Elsevier, 2019)Future changes in tropical cyclone (TC) genesis locations and frequency are explored by identifying relationships between TC genesis and dominant daily large-scale patterns, and evaluating the strength of these relationships ... -
Post-apartheid ecologies in the City of Cape Town: an examination of plant functional traits in relation to urban gradients
(Elsevier, 2020)In this study we explore species richness and traits across two urban gradients in the City of Cape Town. The first is the natural-urban boundary and the second is a socio-economic gradient informed by historical race-based ... -
Current status and future prognosis of malaria vector control pesticide ecotoxicology and Xenopus sp.
(Springer, 2020)Anurans from the genus Xenopus have long been used as standard testing organisms and occur naturally in tropical and sub-tropical areas where malaria vector control pesticides are actively used. However, literature on the ... -
To what extent can mine rehabilitation restore recreational use of forest land? Learning from 50 years of practice in southwest Australia
(Elsevier, 2019)When mining affects natural or semi-natural ecosystems such as forests, rehabilitation often aims at restoring biodiversity. However, to what extent does rehabilitation also restore cultural ecosystem services? This paper ... -
The role of innovation and knowledge networks as a policy mechanism towards more resilient peripheral regions
(Elsevier, 2020)The potential role of innovation and knowledge networks in regional growth and development is well recognized. However, there has been scant reflection on its role as a policy mechanism, specifically for peripheral regions. ... -
Contrasting indoor and ambient particulate matter concentrations and thermal comfort in coal and non-coal burning households at South Africa Highveld
(Elsevier, 2020)One of the key challenges noted in the sustainable development goals for good health and wellbeing (SDGs 3) is both ambient and household air pollution. Household solid fuel combustion represents one of the biggest threat ... -
Avian interspecific differences in VKOR activity and inhibition: insights from amino acid sequence and mRNA expression ratio of VKORC1 and VKORC1L1
(Elsevier, 2020)Worldwide use of anticoagulant rodenticides (ARs) for rodents control has frequently led to secondary poisoning of non-target animals, especially raptors. In order to suggest some factors that may help considering the ... -
A note on the behaviour of a kernel-smoothed kernel density estimator
(Elsevier, 2020)Kernel density estimators have been studied in great detail. In this note a new family of kernels, depending on a parameter , is obtained by kernel-smoothing an initial kernel density estimator. Under certain conditions, ...
