Observing relativistic features in large-scale structure surveys - I. Multipoles of the power spectrum
(Oxford University Press, 2021)Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation and the possibility of constraining novel ... -
Occurrences, levels and risk assessment studies of emergingpollutants (pharmaceuticals, perfluoroalkyl and endocrine disruptingcompounds) infish samples from Kalk Bay harbour, South Africa
(Elsevier, 2019)A comprehensive analysis of 15 target chemical compounds (pharmaceuticals and personal care product,perfluoroalkyl compounds and industrial chemicals) were carried out to determine their concentrationsin selected commercially ... -
Octupole correlations in the structure of O2 bands in the N=88 nuclei150Sm Gd
(American Physical Society, 2013)Knowledge of the exact microscopic structure of the 01 + ground state and first excited 02 + state in 150Sm is required to understand the branching of double β decay to these states from 150Nd. The detailed spectroscopy ... -
Odontogenic myxoma: a clinicopathological study in a South African population
(Blackwell, 2016)Background: Odontogenic myxoma is a benign, locally aggressive neoplasm of the jaws. Prevalence rates range between 0.5% and 17.7% of odontogenic tumours. There are few reports in the literature on this lesion in African ... -
Odorant and gustatory receptors in the tsetse fly Glossina morsitans morsitans
(PLOS, 2014)Tsetse flies use olfactory and gustatory responses, through odorant and gustatory receptors (ORs and GRs), to interact with their environment. Glossina morsitans morsitans genome ORs and GRs were annotated using homologs ... -
Oestrogen, testosterone, cytotoxin and cholinesterase inhibitor removal during reclamation of sewage to drinking water
(Water Research Commission, 2013)Namibia is the driest sub-Saharan country in Africa. Namibia’s capital, Windhoek, reclaims sewage water for domestic use at the Goreangab Water Reclamation Plant (GWRP). Risks associated with sewage effluent and reclaimed ... -
Of dead man's fingers, cord weed and hanging wrack: common brown seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2000)In this, the second in the series on common intertidal seaweeds of the Cape Peninsula, we look at the brown seaweeds common to our rocky shores, with the exception of kelp, which will be covered in the next issue of Veld ... -
Of dinner plate, cochlear and pacman corallines: seven common intertidal encrusting red seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2001)In the fifth and final part of this series of articles on common intertidal seaweeds of the Cape Peninsula, we look at encrusting coralline algae. These encrusting coralline and red seaweeds are widespread in shallow waters ... -
Of purple laver, tongue weed and hedgehog seaweed: common red seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2001)The fourth part of our series on the common intertidal seaweeds of the Cape Peninsula looks at the red seaweeds, which form by far the largest group of seaweeds on the Peninsula and dominate the mid to lower intertidal ... -
Of sea bamboo, split fan kelp and bladder kelp: three common kelp species of the Cape Peninsula and West Coast
(Botanical Society of South Africa, 2001)The third part in our series on the common intertidal seaweeds of the Cape Peninsula looks at the kelps, the giant brown seaweeds that occur in the subtidal and intertidal gullies of the Cape Peninsula and the west coast. ... -
Of sea lettuces and green sea intestines: common intertidal green seaweeds of the Cape Peninsula
(Botanical Society of South Africa, 2000)Most of us know seaweed as that slippery stuff growing on the rocks or lying strewn along the beach at low tide making the beach smell. But do we really know much about them? Although not entirely true, seaweeds (or marine ... -
Oligosaccharides production from coprophilous fungi: An emerging functional food with potential health-promoting properties
(Elsevier, 2022)Functional foods are essential food products that possess health-promoting properties for the treatment of infectious diseases. In addition, they provide energy and nutrients, which are required for growth and survival. ... -
On maximal inequalities via comparison principle
(SpringerOpen, 2015)Under certain conditions, we prove a new class of one-sided, weighted, maximal inequalities for a standard Brownian motion. Our method of proof is mainly based on a comparison principle for solutions of a system of ... -
On multiple classes of gamma-ray bursts, as deduced from autocorrelation functions or bivariate duration/hardness ratio distributions
(Oxford University Press, 2012)Autocorrelation functions (ACFs) of 119 gamma-ray bursts (GRBs) monitored by the Burst Alert Telescope (BAT) on Swift are calculated. Contrasting with previous results for smaller numbers of bursts from other missions, ... -

On soft quasi-pseudometric spaces
(Elsevier, 2021)In this article, we introduce the concept of a soft quasi-pseudometric space. We show that every soft quasi-pseudometric induces a compatible quasi-pseudometric on the collection of all soft points of the absolute soft ... -
On the design of smart parking networks in the smart cities: an optimal sensor placement model
(MDPI, 2015)Smart parking is a typical IoT application that can benefit from advances in sensor, actuator and RFID technologies to provide many services to its users and parking owners of a smart city. This paper considers a smart ... -
On the Evolution Equation for Modelling the Covid-19 Pandemic
(2021)The paper introduces and discusses the evolution equation, and, based exclusively on this equation, considers random walk models for the time series available on the daily confirmed Covid-19 cases for different countries. ... -
On the exact constants in one-sided maximal inequalitiesfor Bessel processes
(Taylor and Francis Group, 2023)In this paper, we establish a one-sided maximal moment inequalitywith exact constants for Bessel processes. As a consequence, weobtain an exact constant in the Burkholder-Gundy inequality. Theproof of our main result is ... -
On the nature of the variable star UNSW-V-760
(Oxford University Press, 2011)The results of multicolour photometric monitoring over several nights of the probable X-ray source UNSW-V-760 are presented. Drawing on both present and past observations, it is shown that the star is multiperiodic and ...
