Comparative evaluation of pharmacy students’ knowledge and skills in maternal and child health: Traditional versus integrated curriculum
(MDPI, 2022): Reducing maternal and child mortality is a health priority in South Africa. Therefore, health professional education should produce graduates that can meet these needs. This study compared the maternal and child health ... -
Comparative in vitro transportation of pentamidine across the blood-brain barrier using polycaprolactone nanoparticles and phosphatidylcholine liposomes
(UWC, 2019)Nanoparticles (NPs) have gained importance in addressing drug delivery challenges across biological barriers. Here, we reformulated pentamidine, a drug used to treat Human African Trypanosomiasis (HAT) in polymer based ... -
Comparative phylogeography of parasitic Laelaps mites contribute new insights into the specialist-generalist variation hypothesis (SGVH)
(BMC, 2018)BACKGROUND: The specialist-generalist variation hypothesis (SGVH) in parasites suggests that, due to patchiness in habitat (host availability), specialist species will show more subdivided population structure when compared ... -
Comparative proteomics analysis between maize and sorghum uncovers important proteins and metabolic pathways mediating drought tolerance
(MDPI, 2023)Drought severely affects crop yield and yield stability. Maize and sorghum are major crops in Africa and globally, and both are negatively impacted by drought. However, sorghum has a better ability to withstand drought ... -
A comparative review of decision support tools routinely used by selected transboundary River Basin Organisations
(Taylor and Francis, 2021)As human pressures on water resources increase, the data and decision support (DS) tools used in the governance, development and management of transboundary rivers are likely to become increasingly important. There are no ... -
Comparative study of admissions criteria of a selection of South African universities
(Stellenbosch University, 2011)Summary: The new school-leaving certificate, the National Senior Certificate (NSC), was awarded for the first time in 2008. This necessitated a relook at the entrance requirements for university, as the school subjects ... -
Comparative study of the antioxidant constituents, activities and the gc-ms quantification and identification of fatty acids of four selected helichrysum species
(MDPI, 2022)Helichrysum Mill. (Asteraceae) is a plant genus comprising distinctively of aromatic plants of about 500–600 species. Since most of these plants have not been previously studied, extensive profiling helps to validate ... -
Comparative study on the topical and transdermal delivery of diclofenac incorporated in nano-emulsions, nano-emulgels, and a colloidal suspension
(Springer, 2022)Transdermal delivery of active pharmaceutical ingredients (APIs) can be challenging, since the skin possesses a rate-limiting barrier, which may be overcome when APIs possess certain ideal physicochemical properties. The ... -
Comparative study: the effect of annealing conditions on the properties of P3HT:PCBM blends
(Springer Verlag, 2013)This paper presents a detailed study on the role of various annealing treatments on organic poly(3-hexylthiophene) and [6]-phenyl-C61-butyric acid methyl ester blends under different experimental conditions. A combination ... -
Comparative venom toxin analyses of Nigerian viperidae and elapidae snakes
(Elsevier, 2023)Envenoming by snakebite is a serious health problem that maims and kills a large number of people, primarily in rural areas of developing African countries. The first comparative venom proteomic analyses of four snakes ... -
Comparative whole corona fingerprinting and protein adsorption thermodynamics of PLGA and PCL nanoparticles in human serum
(Elsevier, 2020)Nanoparticles (NPs) based on biocompatible and biodegradable polymers such as poly(lactic-co-glycolic acid) (PLGA) and polycaprolactone (PCL) represent effective systems for systemic drug delivery. Upon injection into the ... -
Comparing community structure on shells of the abalone Haliotis midae and adjacent rock: implications for biodiversity
(Springer Verlag, 2013)This paper concerns the effects on biodiversity of depletion 24 of the South African abalone Haliotis midae, which is a long-lived species with a large corrugated shell that provides a habitat for diverse benthic organisms. ... -
Comparing galaxy clustering in horizon-agn simulated light-cone mocks and video observations
(Oxford University Press, 2019-04-12)Hydrodynamical cosmological simulations have recently made great advances in reproducing galaxy mass assembly over cosmic time – as often quantified from the comparison of their predicted stellar mass functions to observed ... -

A comparison between the anthropological and modern day uses of this indigenous herb
(Conference: SA Medical Research Council 6th Annual Research Conference, 2012)Sceletium tortuosum (Fig. 1) is a scrambling succulent ground cover indigenous to the Western and Eastern Cape. It has probably been used for centuries as a mood-altering drug, especially by the Khoisan hunters and Nama ... -
Comparison of CO2 capture by ex-situ accelerated carbonation and in in-situ naturally weathered coal fly ash
(Elsevier, 2013)Natural weathering at coal power plants ash dams occurs via processes such as carbonation, dissolution, co-precipitation and fluid transport mechanisms which are responsible for the long-term chemical, physical and geochemical ... -
A Comparison of deep learning architectures for optical galaxy morphology classification
(International Conference on Electrical, Computer and Energy Technologies (ICECET), 2021)The classification of galaxy morphology plays a crucial role in understanding galaxy formation and evolution. Traditionally, this process is done manually. The emergence of deep learning techniques has given room for the ... -
A comparison of Einstein-Boltzmann solvers for testing General Relativity
(American Physical Society, 2018)We compare Einstein-Boltzmann solvers that include modifications to General Relativity and find that, for a wide range of models and parameters, they agree to a high level of precision. We look at three general purpose codes ... -
A comparison of ensemble and deep learning algorithms to model groundwater levels in a data-scarce aquifer of Southern Africa
