(Journal of Inorganic and Organometallic Polymers and Materials, 2023)This contribution reports on the development of two versatile and efficient methods, namely the green and gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, and further their growth inhibition ... -
Influence of termites on the soil seed bank in an African savannah
(Wiley, 2018)In savannah ecosystems, termites drive key ecosystem processes, such as primary production through creation of patchiness in soil nutrients availability around their nests. In this study, we evaluated the role of termites ... -
Informal land sale and housing in the periphery of Pointe-Noire
(GIGA German Institute of Global and Area Studies, 2016)This article examines the relations between practices in informal land transactions under customary tenure and spatial differentiation among suburbs in the periphery of the city of Pointe-Noire, Congo- Brazzaville. Urban ... -
Information protection in video relay services
(ACM, 2013)This work in progress paper reports on initial research into the protection of information of the individuals that make use of video relay services. Our research team has developed an application called SignSupport, to aid ... -
Information security at South African universities-Implications for biomedical research
(Oxford University Press, 2020)In South Africa, a similar regulation strategy to the European Union General Data Protection Regulation, called the Protection of Personal Information Act (No 4 of 2013) (POPIA), will be implemented, with a view to ... -
Infrared luminosity functions and dust mass functions in the EAGLE simulation
(Oxford University Press, 2020)We present infrared luminosity functions and dust mass functions for the EAGLE cosmological simulation, based on synthetic multiwavelength observations generated with the SKIRT radiative transfer code. In the local Universe, ... -
The infrared-radio correlation of star-forming galaxies is strongly M∗-dependent but nearly redshift-invariant since z ∼4
(EDP Sciences, 2021)Over the past decade, several works have used the ratio between total (rest 8-1000 μm) infrared and radio (rest 1.4 GHz) luminosity in star-forming galaxies (qIR), often referred to as the infrared-radio correlation (IRRC), ... -
Infuence of Synthesis Method on Structural, Morphological, Magnetic, and Antimicrobial Properties of Fe‑Ag Nanoparticles
(Springer, 2023)This contribution reports on the development of two versatile and efcient methods, namely the green and gamma radiolysis for Fe-Ag nanoparticles (NPs) synthesis, characterization, and further their growth inhibition potential ... -
Inhibiting CDK6 activity by quercetin is an attractive strategy for cancer therapy
(American Chemical Society, 2020)Cyclin-dependent kinase 6 (CDK6) is a potential drug target that plays an important role in the progression of different types of cancers. We performed in silico and in vitro screening of different natural compounds and ... -
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 ... -
Inhibition of HIV-1 enzymes, antioxidant and anti-inflammatory activities of Plectranthus barbatus
(Elsevier, 213)Ethnopharmacological relevance: Plectranthus barbatus is widely used in African countries as an herbal remedy to manage HIV/AIDS and related conditions. Aim of the study: To investigate the HIV-1 inhibitory, anti-inflammatory ... -
Inhibition of NOS- like activity in maize alters the expression of genes involved in H2O2 scavenging and glycine betaine biosynthesis
(Nature Publishing Group, 2018)Nitric oxide synthase-like activity contributes to the production of nitric oxide in plants, which controls plant responses to stress. This study investigates if changes in ascorbate peroxidase enzymatic activity and ... -
