A tripartite approach to ensure municipal service delivery. The case of a mining town in South Africa
(CCAU, 2019)
Postmasburg, a small mining town, has been an agricultural centre for the past 120 years, the iron ore mining being the only diversifying factor to the local economy. Mining endeavours resulted in the traditional boom-town ...
Replicating the CBOE VIX using a synthetic volatility index trading algorithm
(Taylor & Francis, 2019)
This article tests whether a correlation exists between a stochastic
synthetic volatility index (SVIX) and the Chicago Board Options Exchange (CBOE)
volatility index (VIX) and assesses the success of the indicators’ ...
Changes in abundance of fish-parasitic gnathiid isopods associated with warm-water bleaching events on the northern Great Barrier Reef
(Springer, 2019)
Mass coral bleaching events due to rising seawater temperatures are occurring with increasing frequency and are among the most conspicuous consequences of human-induced climate change. While bleaching events have clear ...
Hilbert and Thompson isometries on cones in JB-algebras
(Springer, 2019)
Hilbert’s and Thompson’s metric spaces on the interior of cones in JB-algebras are important
examples of symmetric Banach-Finsler spaces. In this paper we characterize the Hilbert’s
metric isometries on the interiors of ...
New insights into the metagenomic link between pre‐treatment method, addition of an inoculum and biomethane yield during anaerobic digestion of water hyacinth (Eichhornia crassipes)
(Wiley, 2019)
BACKGROUND
Water hyacinth (Eichhornia crassipes) is a fast growing water weed that threatens the aquatic ecosystem and human activities, hence control of the plant is essential. One such control approach is to harvest and ...
LC-ESI/MS/MS analysis of neonicotinoids in urine of very low birth weight infants at birth
(PLoS, 2019)
Objectives
Neonicotinoid insecticides are widely used systemic pesticides with nicotinic acetylcholine receptor agonist activity that are a concern as environmental pollutants. Neonicotinoids in humans and the environment ...
Plasmonic detection of glucose in serum based on biocatalytic shape-altering of gold nanostars
(MDPI, 2019)
Nanoparticles have been used as signal transducers for optical readouts in biosensors.
Optical approaches are cost-e ective with easy readout formats for clinical diagnosis. We present a
glucose biosensor based on the ...
Editorial – evolution, revolution, climate change and current EIA
(Taylor & Francis, 2019)
Do we need impact assessment (IA) evolution or revolution? This was the question discussed at this year’s IAIA conference in Brisbane, Australia. And whilst the answer to this simple question is – inevitably – rather ...
Constraints on the emission region of 3C 279 during strong flares in 2014 and 2015 through VHE γ-ray observations with H.E.S.S.
(EDP Sciences, 2019)
The flat spectrum radio quasar 3C 279 is known to exhibit pronounced variability in the high-energy (100 MeV < E < 100 GeV) γ-ray band, which is continuously monitored with Fermi-LAT. During two periods of high activity ...
A numerical study of cosmic proton modulation using AMS-02 observations
(IOP Publishing, 2019)
Since 2011 May, the Alpha Magnetic Spectrometer (AMS-02) on board the International Space Station has provided monthly cosmic proton fluxes for various low-rigidity levels (P<50 GV). These precise measurements, in terms ...
