A catalogue with keys to the non-geniculate coralline algae (Corallinales, Rhodophyta) of South Africa
(Elsevier, 2008)Non-geniculate coralline red algae are common in all of the world’s oceans, where they often occupy close to 100% of the primary rocky substratum. The South African rocky subtidal and intertidal habitats in particular, ... -
Catalytic cracking of naphtha: The effect of Fe and Cr impregnated ZSM-5 on olefin selectivity
(Springer Nature, 2018)This study focuses on the modification of ZSM-5 in order to enhance the catalytic cracking of refinery naphtha to produce light olefins. ZSM-5 was metal modified using different loadings (0.5–5 wt%) of Fe and Cr via the ... -
Catalytic reduction of 4-nitrophenol and methylene blue by biogenic gold nanoparticles synthesized using Carpobrotus edulis fruit (sour fig) extract
(SAGE Publications, 2022)Along with the increasing requirement for efficient organic conversions using green chemistry, there is a need to develop highly efficient and eco-friendly catalytic reaction systems. Gold nanoparticles (AuNPs)-based ... -
Causes and consequences of sperm mitochondrial dysfunction
(Wiley-Blackwell, 2020)Mitochondria have multiple functions, including synthesis of adenine triphosphate, production of reactive oxygen species, calcium signalling, thermogenesis and apoptosis. Mitochondria have a significant contribution in ... -
Causes and patterns of morbidity and mortality in Afghanistan: Joint estimation of multiple causes in the neonatal period
(Springer, 2014)This paper focuses on investigating the leading cause(s) of death and preventable factors in Afghanistan, using data from verbal autopsies of infant deaths. We are of the view that the presence of a disease in a person ... -
Ceers key paper. I. An early look into the first 500myr of galaxy formation with jwst
(American Astronomical Society, 2023)We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets galaxy formation from z ∼ 0.5 to >10 using ... -
Cell phone notification via bluetooth for Web 2.0 applications
(Telkom, 2009)This paper discusses how an Instant Messaging application on a computer can use Bluetooth in order to provide vibration notification on a mobile phone. The initial motivation was to aid Deaf1 office workers to know when ... -
Cellular and molecular targets of waterbuck repellent blend odors in antennae of glossina fuscipes fuscipes newstead, 1910
(Frontiers Media S.A., 2020)Insects that transmit many of the world’s deadliest animal diseases, for instance trypanosomosis, find their suitable hosts and avoid non-preferred hosts mostly through olfactory cues. The waterbuck repellent blend (WRB) ... -
Cellular Characterization of SARS Coronavirus Nucleocapsid
(Leibniz Research Centre for Working Environment and Human Factors, 2004)The Severe and Acute Respiratory Syndrome coronavirus (SARS CoV) is a newly-emerged virus that caused an outbreak of atypical pneumonia in the winter of 2002-2003. Polyclonal antibodies raised against the nucleocapsid (N) ... -
A census of the pulsar population observed with the international LOFAR station FR606 at low frequencies (25–80 MHz)
(EDP Sciences, 2020)ontext. To date, only 69 pulsars have been identified with a detected pulsed radio emission below 100 MHz. A LOFAR-core LBA census and a dedicated campaign with the Nançay LOFAR station in stand-alone mode were carried out ... -
Ceria-Spiderweb Nanosheets Unlock the Energy-Storage Properties in the “Sleeping” Triplite (Mn2(PO4)F)
(American Chemical Society, 2021)Rechargeable aqueous mobile-ion batteries (RAMIBs) are attractive next-generation battery technologies. Manganese fluorophosphate (triplite), Mn2(PO4)F (MFP), and its ceria- and carbon-coated composites (i.e., MFP-CeO2 and ... -
Challenges for the adoption of ICT for diabetes selfmanagement in South Africa
(University of the Western Cape, 2019)The increasing disease burden in developing countries inhibits the provision of quality care to citizens. However, the increased availability of information communication and technology (ICT) tools makes this a viable ... -
Challenges of biobanking in South Africa to facilitate indigenous research in an environment burdened with human immunodeficiency virus, tuberculosis, and emerging non-communicable diseases
(Mary Ann Liebert, Inc., 2013)The high burden of infectious diseases and the growing problem of noncommunicable and metabolic disease syndromes in South Africa (SA) forces a more focused research approach to facilitate cutting-edge scientific growth ... -
Challenges relating to comparison of flavonoid glycosides dissolution profiles from Sutherlandia frutescens products
