Monkeypox during Covid-19 era in Africa: Current challenges and recommendations
(Elsevier, 2022)In May 2022, monkeypox virus (MPXV) outbreak was confirmed amid the coronavirus disease 2019 (COVID-19) pandemic in many parts of the world including Africa. This is the largest outbreak since monkeypox (MPX) was first ... -
Monoclonal Antibodies targeting the HR2 Domain and the region immediately upstream of the HR2 of the S Protein neutralize in Vitro Infection of Severe Acute Respiratory Syndrome Coronavirus
(American Society for Microbiology, 2006)We have previously shown that an Escherichia coli-expressed, denatured spike (S) protein fragment of the severe acute respiratory coronavirus, containing residues 1029 to 1192 which include the heptad repeat 2 (HR2) ... -
Montmorillonite modified by CNx supported Pt for methanol oxidation
(Elsevier, 2013)A composite support based on nature clay, i.e. montmorillonite (MMT), shows great promise as support materials for Pt electrocatalyst for the methanol oxidation reaction in fuel cell anodes. The reported composite support ... -
More on the nature of the variable star UNSW-V-760
(Oxford University Press, 2012)The results of two multicolour time-series photometric observing runs, separated by about two months, are presented. The same periodicities previously detected in photometry of UNSWV- 760 are still present, albeit at ... -
Morpho-physiological, biochemical, and genetic responses to salinity in medicago truncatula
(MDPI, 2021)We used an integrated morpho-physiological, biochemical, and genetic approach to investigate the salt responses of four lines (TN1.11, TN6.18, JA17, and A10) of Medicago truncatula. Results showed that TN1.11 exhibited a ... -
Morphological and physiological responses of Calobota sericea plants subjected to water limitation and subsequent rewatering
(Taylor and Francis Group, 2021)Calobota sericea is a native legume of South Africa, confined to the water-limited rangelands, and it has recently been prioritised for additional characterisation regarding its pasture potential. In this study, we examined ... -
Morphometric and structural analysis of Florida manateespermatozoa
(Wiley, 2022)Sperm characteristics, such as sperm morphology and sperm morphometry areimportant in assessing sperm quality. This is especially important for the man-agement and conservation of endangered and exotic species, like the ... -
Moving ICTD research beyond bungee jumping: practical case studies and recommendations
(Institute of Electrical and Electronics Engineers, 2016)The global spread of Internet and mobile communications has been accompanied by a growing interest in how information and communication technologies (ICTs) can contribute to social and economic development. There are a ... -
Mufasa: The assembly of the red sequence
(Oxford University Press, 2017)We examine the growth and evolution of quenched galaxies in the Mufasa cosmo- logical hydrodynamic simulations that include an evolving halo mass-based quench- ing prescription, with galaxy colours computed accounting ... -
MUFASA: The strength and evolution of galaxy conformity in various tracers
(Oxford University Press, 2017)We investigate galaxy conformity using the Mufasa cosmological hydrodynamical simulation. We show a bimodal distribution in galaxy colour with radius, albeit with too many low-mass quenched satellite galaxies compared ... -
Multi-drug resistant (MDR) oral Candida species isolated from HIV-positive patients in South Africa and Cameroon
(Elsevier, 2014)Candida species are a common cause of infection in immune-compromised HIV-positive individuals, who are usually treated with the antifungal drug, fluconazole in public hospitals in Africa. However, information about the ... -
Multi-instrument observations of large-scale atmospheric gravity waves/traveling ionospheric disturbances associated with enhanced auroral activity over Svalbard
(Elsevier, 2019-09-03)This study reports on observations of large-scale atmospheric gravity waves/traveling ionospheric disturbances (AGWs/TIDs) using Global Positioning System (GPS) total electron content (TEC) and Fabry–Perot Interferometer’s ... -
Multi-objective optimization of a metal hydride reactor coupled with phase change materials for fast hydrogen sorption time
(Journal of Energy Storage, 2023)Recently, the utilization of phase change materials (PCM) for the heat storage/recovery of the metal hydride's reaction heat has received increasing attention. However, the poor heat management process makes hydrogen ... -

A multi-proxy provenance study of late carboniferous to middle Jurassic sandstones in the Eastern Sverdrup basin and its bearing on arctic palaeogeographic reconstructions
(MDPI, 2023)A multi-proxy provenance study of Late Carboniferous to Middle Jurassic sandstones from the eastern Sverdrup Basin was undertaken employing optical petrography and heavy mineral analysis, chemical analysis of apatite, ... -
Multi-scale perturbation theory II: Solutions and leading-order bispectrum in the ΛcDM universe
(IOP Publishing, 2021)Two-parameter perturbation theory (2PPT) is a framework designed to include the relativistic gravitational effects of small-scale nonlinear structures on the large-scale properties of the Universe. In this paper we use ... -
Multi-scale perturbation theory. Part I. Methodology and leading-order bispectrum corrections in the matter-dominated era
(IOP Publishing Ltd, 2020)Two-parameter perturbation theory is a scheme tailor-made to consistently include nonlinear density contrasts on small scales (< 100 Mpc), whilst retaining a traditional approach to cosmological perturbations in the ... -
Multi-targeted directed ligands for Alzheimer’s disease: design of novel lead coumarin conjugates
(Taylor & Francis, 2018)Alzheimer’s Disease (AD) is a neurodegenerative disease characterized by central nervous system insults with progressive cognitive (memory, attention) and non-cognitive (anxiety, depression) impairments. Pathophysiological ... -
Multi-wavelength properties of radio- and machine-learning-identified counterparts to submillimeter sources in s2cosmos
(The Astrophysical Journal, 2019)We identify multi-wavelength counterparts to 1147 submillimeter sources from the S2COSMOS SCUBA-2 survey of the COSMOS field by employing a recently developed radio+machine-learning method trained on a large sample of ... -
Multi-year trend analysis of childhood immunization uptake and coverage in Nigeria
