Plasmonic metal decorated titanium dioxide thin films for enhanced photodegradation of organic contaminants
(Elsevier, 2017)
Photocatalysis using titanium dioxide as photocatalyst is an efficient way for the removal of organic
contaminants in water using solar energy. In this study, thin
films of copper and silver were deposited on
fused ...
Cloning, expression and characterization of thermostable YdaP from Bacillus licheniformis 9A
(Acta Biochimica Polonica, 2017)
The Bacillus licheniformis ydaP gene encodes for a pyruvate
oxidase that catalyses the oxidative decarboxylation
of pyruvate to acetate and CO2. The YdaP form of
this enzyme was purified about 48.6-folds to homogeneity
in ...
A model of population dynamics of TB in a prison system and application to South Africa
(BioMed Central, 2017)
BACKGROUND: Tuberculosis (TB) continues to spread in South African prisons in particular, as prisons are over-capacitated
and have poor ventilation. The awaiting trial detainees are not screened on admission and are at ...
Generalization of tooltips: An assistive technology extension
(Springer, 2017)
Software applications use tooltips to assist users to improve their understanding of icons. When hovering over an icon with the cursor, a short text description of the icon appears. Text-based tooltips are helpful for users ...
An SEIRS epidemic model with stochastic transmission
(Springer, 2017)
For an SEIRS epidemic model with stochastic perturbations on transmission from the susceptible class to the latent and infectious classes, we prove the existence of global positive solutions. For sufficiently small values ...
Towards a model for user-centred design using a positive deviance approach: A case for diabetes self-management
(University of Cape Town, 2017)
Over the past twenty years there have been substantive efforts across the African continent to ensure penetration and reach of mobile technology to the citizenry. However there continues to be a debate on precisely how ...
Designing a course model for distance-based online bioinformatics training in Africa: the H3ABioNet experience
(Public Library of Science, 2017)
Africa is not unique in its need for basic bioinformatics training for individuals from a diverse
range of academic backgrounds. However, particular logistical challenges in Africa, most
notably access to bioinformatics ...
Insights into the use and affordances of social and collaborative applications for student projects
(South African Institute of Computer Scientists and Information Technologists, 2017)
The use of social and collaborative computing has the potential of assisting learning and improving the ability to work
together as part of a team. Team work is a graduate attribute that students need to acquire before ...
Inhibition of bacteria associated with wound infection by biocompatible green synthesized gold nanoparticles from South African plant extracts
(MDPI, 2017)
Unlike conventional physical and chemical methods, the biogenic synthesis of gold
nanoparticles (GNPs) is considered a green and non-toxic approach to produce biocompatible
GNPs that can be utilized in various biomedical ...
