Abundance and diversity of plant-parasitic nematodes associated with watermelon in Nigeria, with focus on Meloidogyne spp.
(Brill, 2020)Little information is available for nematode pests associated with watermelon in sub-Saharan Africa (SSA). This study recorded the abundance and prevalence of plant-parasitic nematodes from 25 localities across south-west ... -
An amended description of two Gyrodactylus species (Platyhelminthes: Monogenea) parasitizing Antarctic Notothenioid fish
(Cambridge Univ Press, 2020)Species identification based on the morphometry of opisthaptoral hard parts, in combination with internal transcribed spacer ribosomal DNA (ITS rDNA) region sequences, confirmed the presence of four viviparous Gyrodactylus ... -
Apicomplexan diversity of selected southern African snakes and terrapins
(North-West University (South Africa), 2022)Southern Africa has the highest diversity of reptile fauna in Africa. Despite estimates that diversity of reptile associated haematozoans are higher compared to mammals and birds, there is a lack of research regarding ... -
Applying nuclear forensic signatures in response to a nuclear security event from a South African nuclear facility
(North-West University (South Africa), 2022)Uranium ore concentrates, also known as yellowcake, are a critical component of the nuclear fuel cycle and the result of uranium mining and processing. Uranium ore concentrate s refers to a group of uranium chemical compounds ... -
Automatic lemmatisation for Afrikaans
(North-West University, 2006)A lemmatiser is an important component of various human language technology applicalions for any language. At present, a rule-based lemmatiser for Afrikaans already exists, but this lemmatiser produces disappointingly low ... -
The bipyridine adducts of N-phenyldithiocarbamato complexes of Zn(II) and Cd(II); synthesis, spectral, thermal decomposition studies and use as precursors for ZnS and CdS nanoparticles
(Elsevier, 2015)Bipyridine adducts of N-phenyldithiocarbamato complexes, [ML12L2] (M = Cd(II), Zn(II); L1 = N-phenyldithiocarbamate, L2 = 2,2′ bipyridine), have been synthesized and characterised. The decomposition of these complexes to ... -
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 ... -
Characterisation of some Scutellonema species (Tylenchida: Hoplolaimidae) occurring in Botswana, South Africa, Costa Rica and the USA, with description of S. clavicaudatum sp. n. and a molecular phylogeny of the genus
(Brill, 2017)The genus Scutellonema contains more than 40 species of spiral nematodes with enlarged phasmids called scutella. In this study, we provide morphological and molecular characterisation of S. clavicaudatum sp. n., S. ... -
Characterization of wheat nematodes from cultivars in South Africa
(North-West University (South Africa), 2020)Plant-parasitic nematodes (PPNs) naturally live in soil and attack small roots, but some species inhabit and feed in bulbs, buds, stems, leaves, or flowers. This leads to plant weakness and they often appear to suffer from ... -
Coal and coal ash characteristics to understand mineral transformations and slag formation
(Elsevier, 2009)A knowledge of the composition and structure of minerals in coal is necessary in order to understand the mineral transformations and agglomerate or slag formation during combustion or gasification. Coal ash fusibility ...
