A century of taxonomic uncertainty: re-description of two species of tapeworms (Diphyllobothriidea) from Arctic seals
(Springer, 2018)Diphyllobothriid tapeworms are well-known parasites of mammals including humans. Most species are known for centuries, but the validity of many species and their classification are still poorly understood. Based on new ... -
Cephalenchus driekieae n. sp. (Nematoda: Tylenchidae) from South Africa, a new member of the genus with a long pharyngeal overlap
(Exeley, 2020)Cephalenchus driekieae n. sp. is described and illustrated based on its morphological, morphometric, and molecular characteristics. This new species is mainly characterized by its short stylet 11.5 to 13.0 µm, and 13.5 to ... -
Ceratothoa retusa (Schiœdte & Meinert, 1883) (Isopoda, Cymothoidae), a variable species of fish parasitic marine isopod from the Indian Ocean
(Brill Academic Publishers, 2014)Ceratothoa retusa (Schiœdte & Meinert, 1883) is redescribed from the lectotype (here designated) collected from Mozambique, and the range is extended to include the Gulf of Suez in the Red Sea. Ceratothoa retusa is distinctive ... -
Cerebral blood flow in the non-human primate : an in vivo model and drug interventions
(North-West University, 2003)Cerebral blood flow dynamics is an essential component for preserving cerebral integrity. Cerebral blood flow abnormalities are often seen in patients with central nervous system pathologies such as epilepsy, migraine, ... -
Cerebrospinal fluid amino acid profiling of pediatric cases with tuberculous meningitis
(Frontiers Media, 2017)Background: In Africa, tuberculosis is generally regarded as persisting as one of the most devastating infectious diseases. The pediatric population is particularly vulnerable, with infection of the brain in the form of ... -
Cerebrospinal fluid in tuberculous meningitis exhibits only the L-enantiomer of lactic acid
(BioMed Central, 2016)Background: The defining feature of the cerebrospinal fluid (CSF) collected from infants and children with tuberculous meningitis (TBM), derived from an earlier untargeted nuclear magnetic resonance (NMR) metabolomics ... -
Ceropegia terebriformis
(South African National Biodiversity Institute, 2015) -
Certain aspects concerning affirmative action in industry : a literature study
(Potchefstroomse Universiteit vir Christelike Hoer Onderwys, 1996)Die oorgangsfase wat tans in Suid-Afrika plaasvind, het baie veranderinge op verskillende terreine van die samelewing teweeg gebring, insluitend die nywerheid. Verskillende programme vir die opheffing en ontwikkiling van ... -
Certification or qualification: an analysis of formal and non-formal higher education in South Africa
(Faerie Glen, South Africa, 2012) -
Cervical squamous intraepithelial lesions and associated cervical infections in an HIV-positive population in rural Mpumalanga, South Africa
(Wiley, 2013)Background: The incidences of genital human papillomavirus (HPV) infection, associated squamous intraepithelial lesions and cervical squamous cell carcinoma are significantly increased in HIV-positive women. The role of ... -
Cestodes of the order Onchoproteocephalidea II infecting cartilaginous fishes (Elasmobranchii) in South Africa
(North-West University (South Africa), 2022)South Africa is globally classified as the third most biodiverse country on Earth. However, the immense deficiency of taxonomic marine based initiatives, especially regarding parasitological research, within this region ... -
CFD airfoil profile drag calculation using far-field wake analysis
(North-West University (South Africa), 2019)With the ever increasing cost of experimental data and the ultimate decrease of project lifespan from design to implementation it has become the aerodynamicist?s main priority to design and model new ideas with precise ... -
CFD analysis of the heat transfer from a self-launch sailplane radiator
(North-West University (South Africa), 2019)A self-launch sailplane is an aircraft equipped with a retractable engine/propeller combination which can take-off on its own power. The engine can also be used to extend flights if necessary. The engine-driven propeller ... -
CFD analysis of thermal dispersion in a structured packed bed
(SACAM, 2018)Packed beds are generally modelled in a partial manner to avoid computational costs. This implies that only a small portion of the representative bed is modelled explicitly in CFD simulations, usually by assuming ... -
CFD analysis of thermal dispersion in a structured pebble bed
(North-West University, 2019)Heat transfer mechanisms in packed beds are not entirely understood, which gave rise to thermal dispersion correlations that contain considerable amounts of empiricism. The empiricism resulted from incorporating a limited ... -
CFD and systems thermal-hydraulic analysis in the design and safety assessment of high-temperature reactors
(Woodhead Publishing, 2019)An overview is provided of the role of the various levels of CFD in the different stages of the design, analysis and evaluation of very-high-temperature reactor (VHTR) systems and molten salt reactor (MSR) systems. The ... -
CFD applications in the Pebble Bed Modular Reactor Project: a decade of progress
(Elsevier, 2011)Of all the systems and components that have to be designed for a nuclear plant, the Reactor Unit is the most significant since it is at the very heart of the plant. At Pebble Bed Modular Reactor (Pty) Ltd. (PBMR), the ... -
CFD modeling of particle charging and collection in electrostatic precipitators
(Elsevier, 2016)A CFD model was developed to describe the particle laden gas flow through an ESP, particle charging and collection. The corona discharge was modeled using the open source software OpenFOAM to solve the Poison and charge ... -
CFD modelling of air flow through a finned coil heat exchanger to improve heat transfer and pressure drop predictions
(North-West University (South Africa), 2020)In the current study, a method of lessening computational expense and model design effort is investigated for finned coil heat exchangers (FCHXs) by using STAR-CCM+ as simulation tool. The simulation model prediction ...
