Colloidal-route synthesis of N-butylaniline capped ZnS and CdS nanoparticles
(Elsevier, 2013)A new secondary amine (N-butyl aniline) has been used as surfactant to synthesize monodispersed ZnS and CdS nanoparticles via the colloidal-route. The structural nature and optical properties of the as-synthesized nanoparticles ... -
A combination part of speech tagger using selected voting methods
(IEEE, 2019)The development of resources in any language is an expensive process, many languages, including the indigenous languages of South Africa, can be classified as being resource scarce, or lacking in tagging resources. This ... -
Combinatorial plasma sputtering of PtxPdy thin film electrocatalysts for aqueous SO2 electro-oxidation
(Springer, 2015)A combinatorial sputtering system, based on magnetron enhanced plasma sputtering, was employed in the syntheses of PtxPdy thin film catalysts, and a multi-channel potentiostat allowed for high-throughput parallel screening ... -
Combinatorial synthesis of gold-based thin films for improved electrocatalytic conversion of CO2 to CO
(Springer, 2015)Carbon dioxide electroreduction (CO2ER) was studied on 35 gold-based thin film catalysts sputtered on glassy carbon disks. A sputter-down setup was used for the deposition of these thin films in a combinatorial manner. ... -
The combined modulation of Jovian and Galactic electrons in the heliosphere
(PoS, 2017)The propagation and modulation of electrons in the heliosphere play a significant role in improving our understanding and assessment of the competing processes of solar modulation. An in-house developed, full three-dimensional ... -
Combined sinh-cosh-Gordon equation: symmetry reductions, exact solutions and conservation laws
(Taylor & Francis and NISC, 2014)In this paper we study the combined sinh-cosh-Gordon equation, which arises in mathematical physics and has a wide range of scientific applications that range from chemical reactions to water surface gravity waves. We ... -
Combined tarsal and carpal tunnel syndrome in mucolipidosis type III
(Wiley, 2009)Mucolipidosis type III (MLIII) (MIM# 252600) is an uncommon autosomal recessive disorder that results from uridine 5′-diphosphate-N-acetylglucosamine: lysosomal hydrolase N-acetyl-1-phosphotransferase or UDP-GlcNAc ... -
Combining chemical permeation enhancers for synergistic effects
(Springer, 2016)Currently, macromolecular drugs such as proteins are mainly administered by means of injections due to their low intestinal epithelial permeability and poor stability in the gastrointestinal tract. This study ... -
Combining historical remote sensing, digital soil mapping and hydrological modelling to produce solutions for infrastructure damage in Cosmo City, South Africa
(MDPI, 2020)Urbanization and hydrology have an interactive relationship, as urbanization changing the hydrology of a system and the hydrology commonly causing structural damage to the infrastructure. Hydrological modelling has been ... -
Combining physicochemical properties and microbiome data to evaluate the water quality of South African drinking water production plants
(Public Library of Science, 2020)Anthropogenic activities in catchments used for drinking water production largely contaminates source waters, and this may impact the quality of the final drinking water product. These contaminants may also affect taxonomic ... -
Combining scenario and historical data in the loss distribution approach: a new procedure that incorporates measures of agreement between scenarios and historical data
(Infopro Digital Risk Limited, 2015)Many banks use the loss distribution approach in their advanced measurement models to estimate regulatory or economic capital. This boils down to estimating the 99.9% value-at-risk of the aggregate loss distribution and ... -
Comments on: Tests for multivariate normalit: a critical review with emphasis on weighted L2 -statistics
(Springer, 2020)We discuss extension of the BHEP test to more general families of distributions -
Comments: a review of testing procedures based on the characteristic function
(SASA, 2016)First of all, we would like to congratulate the author for writing this interesting and timely review paper on testing procedures based on the empirical characteristic function. The exposition of the ideas and methods is ... -
Commicarpus pentandrus
(National Botanical Institute (South Africa), 2013)This is the first species of the Nyctaginaceae to be illustrated in Flowering Plants of Africa. It is commonly known as the four o’clock family, as most members have flowers that open in the late afternoon to early evening. ... -
Communication between information system development team members from different cultural contexts: a case study
(IADIS Press, 2013)The aim of this study was to investigate how communication is affected by the different cultural contexts of information system development (ISD) team members in order to achieve ISD project results. The study investigated ... -
Community caregivers' perspectives of community well-being in a mining community
(AOSIS, 2017)Mining communities throughout the Southern African Development Community are faced with numerous challenges impacting on their wellbeing. As part of an integrative multidisciplinary research project, this study sought to ... -
Community composition and functions of endophytic bacteria of Bt maize
(ASSAf, 2018)We investigated the potential effects of genetic modification of Bt maize on the community composition and functions of bacterial endophytes associated with transgenic maize (Bt MON 810) in comparison with its isogenic ... -
Community participation in crime prevention: informal social control practices in Site B, Khayelitsha Township
(Mediterranean Center of Social and Educational Research (MCSER), 2013)The role of informal social controls and their sanctions are still given little attention in crime prevention field. Some people still regard fighting and preventing crime as the work of the government and its agencies. ...
