Estimating above-ground biomass in sub-tropical buffer zone community Forests, Nepal, using Sentinel 2 data
(MDPI, 2018)Accurate assessment of above-ground biomass (AGB) is important for the sustainable management of forests, especially buffer zone (areas within the protected area, where restrictions are placed upon resource use and special ... -
Estimating and monitoring land surface phenology in rangelands: A review of progress and challenges
(MPDI, 2021)Land surface phenology (LSP) has been extensively explored from global archives of satellite observations to track and monitor the seasonality of rangeland ecosystems in response to climate change. Long term monitoring ... -
Estimating leopard density across the highly modified human-dominated landscape of the Western Cape, South Africa
(Cambridge University, 2021)Apex predators play a critical role in maintaining the health of ecosystems but are highly susceptible to habitat degradation and loss caused by land-use changes, and to anthropogenic mortality. The leopard Panthera ... -
Estimating the budget impact of adopting tenofovir/emtricitabine for pre-exposure prophylaxis of HIV in the public health sector in Namibia (2021 – 2023)
(Elsevier, 2022)Namibia started implementing pre-exposure prophylaxis (PrEP) of Human Immunodeficiency Virus (HIV) in 2016, no study to determine its budget impact has been conducted. This study, therefore, aimed to estimate the budget ... -
Estimating the burden of disease attributable to excess body weight in South Africa in 2000
(South African Medical Association, 2007)OBJECTIVE: To estimate the burden of disease attributable to excess body weight using the body mass index (BMI), by age and sex, in South Africa in 2000. DESIGN: World Health Organization comparative risk assessment ... -
Estimating the electron energy and the strength of the electric field within sprites using ground-based optical data observed over South African storms
(Elsevier, 2021)We present a new simplified method to estimate the characteristic electron energy and electric field within a mesospheric transient luminous event using ground-based calibrated and filtered optical data. We assume ... -
Estimation of maize foliar temperature and stomatal conductance as indicators of water stress based on optical and thermal imagery acquired using an unmanned aerial vehicle (uav) platform
(MDPI, 2022)Climatic variability and extreme weather events impact agricultural production, especially in sub-Saharan smallholder cropping systems, which are commonly rainfed. Hence, the development of early warning systems regarding ... -
Estimation of recharge using a revised CRD method
(Water Research Commission, 2001)The cumulative rainfall departure (CRD) method, based on the water-balance principle, is often used for mimicking of water level fluctuations. Because of its simplicity and minimal requirement of spatial data, the CRD ... -
Estimation of the coherence time of stochastic oscillations from modest samples
(Oxford University Press, 2012)‘Quasi-periodic’ or ‘solar-like’ oscillations can be described by three parameters – a characteristic frequency, a coherence time (or ‘quality factor’) and the variance of the random driving process. This paper is concerned ... -
An estuary ecosystem classification that encompasses biogeography and a high diversity of types in support of protection and management
(Taylor & Francis, 2020)For nearly three decades, the Whitfield (1992) characterisation scheme served as a reference framework to type South African estuaries. We outline a revised ecosystem classification scheme that incorporates biogeographical ... -
Ethanol oxidation activity and structure of carbon-supported Pt-modified PdSn-SnO2 influenced by different stabilizers
(Elsevier, 2013)PdSn-SnO2 nanoparticles supported on Vulcan XC-72 carbon were synthesized by chemical reduction in the presence of three different stabilizing agents: ethylene diamine tetra-acetic acid (EDTA), sodium citrate (Nacitrate) ... -
Ethical and legal implications of whole genome and whole exome sequencing in African populations
(BioMed Central, 2013)BACKGROUND: Rapid advances in high throughput genomic technologies and next generation sequencing are making medical genomic research more readily accessible and affordable, including the sequencing of patient and control ... -
Ethical considerations in using student data in an era of ‘big data’
(2015)Learning with technology enables the collection of data on students at a level unprecedented in face-to-face tuition and paper-based academic administration. Universities see the advantage in tracking students’ engagement ... -
