The emergence of the 4th industrial revolution has brought about several technological advancements in which blockchain fulfils a prominent role. To most people, the notion of blockchain is merely synonymous with the popular ...
The search for an eco-friendly, non-toxic, economical and efficient means of cleaning water through bioremediation is not only more favourable but critical to maintaining water quality globally especially in water-scarce ...
Many researchers believe that no matter what path a country takes towards economic development the end result will lead to urbanisation. Rapid urban growth will have a major influence on the social, economic and political ...
Ingham, M; Das, Sonali; Yadavalli, S(UNISA, 2017-10)
This paper identified change points in the production volumes and sales of various Industrial Metals in South Africa from the period 2003 – 2016. The socio-economic environment in which the mining sector operates is ...
The stem bark extract of Suregada zanzibariensis afforded a previously undescribed ent-abietane diterpenoid trivially named mangiolide (1) and a known jolkinolide B (2) via anticancer bioassay-guided fractionation. The ...

The use of polymer nanocomposites as novel materials for water remediation has emerged as a promising alternative for disinfection of bacteria contaminated water. Sodium alginate, a natural biopolymer has been investigated ...
The developing world is seeing rapid growth in the availability of biological mass spectrometry (MS), particularly through core facilities. As proteomics and metabolomics becomes locally feasible for investigators in these ...
The need for greener extraction procedures that are quick and efficient has prompted the evolution of pressurized hot water extraction (PHWE). Here, the extraction of flavonoids from Bidens pilosa was demonstrated using ...
Recent evidence has shown that consumption of plants rich in phenolic compounds has health-promoting benefits. Amongst these plants, include Moringa oleifera Lam. (Moringaceae) which has gained significant attention due ...
To counteract biotic stress factors, plants employ multilayered defense mechanisms responsive to pathogen-derived elicitor molecules, and regulated by different phytohormones and signaling molecules. Here, lipopolysaccharide ...
