Importance and relevance of phytochemicals present in Galenia Africana
(Hindawi, 2022)Many people in developing countries rely primarily on medicinal plants as their main source of healthcare, particularly for the treatment of skin infections. Despite the widespread use of medicinal plants, there is a lack ... -
Structure and biosynthesis of carotenoids produced by a novel planococcus sp. isolated from South Africa
(Microb Cell Fac, 2022)Background: The genus Planococcus is comprised of halophilic bacteria generally reported for the production of carotenoid pigments and biosurfactants. In previous work, we showed that the culturing of the orange-pigmented ... -
An integrated approach of reservoir characterization of Y gas feld in central Bredasdorp Basin, South Africa
(Springer, 2022)The study attempts to address the knowledge gap in the Bredasdorp Basin Ofshore South Africa by using newly acquired seismic data with an enhanced resolution, integrating core and well log to provide a solution. The main ... -
Metal–metal correlation of biodegraded crude oil and associated economic crops from the Eastern Dahomey Basin, Nigeria
(MDPI, 2022)The presence of heavy metals in plants from oil sand deposits may reflect mineralization resulting from petroleum biodegradation. Petroleum composition and heavy metal analyses were performed using thermal desorption gas ... -
Crataegus monogyna and centella asiatica extracts as inhibitors of cathepsin s
(Horizon Research Publishing, 2022)Cathepsin cysteine proteases such as cathepsin S are responsible for the unfavorable and irreversible dysregulation of extracellular matrix (ECM) proteolysis found in cardiomyopathy, heart valve diseases and atherosclerosis. ... -
A Comparison of deep learning architectures for optical galaxy morphology classification
(International Conference on Electrical, Computer and Energy Technologies (ICECET), 2021)The classification of galaxy morphology plays a crucial role in understanding galaxy formation and evolution. Traditionally, this process is done manually. The emergence of deep learning techniques has given room for the ... -
Constraining the neutrino mass using a multitracer combination of two galaxy surveys and cosmic microwave background lensing
(Oxford University Press, 2022)Measuring the total neutrino mass is one of the most exciting opportunities available with next-generation cosmological data sets. We study the possibility of detecting the total neutrino mass using large-scale clustering ... -
Establishing minion sequencing and genome assembly procedures for the analysis of the rooibos (aspalathus linearis) genome
(MDPI, 2022)While plant genome analysis is gaining speed worldwide, few plant genomes have been sequenced and analyzed on the African continent. Yet, this information holds the potential to transform diverse industries as it unlocks ... -
Genetic variation in responses to salt stress in Tunisian populations of Medicago ciliaris
(MDPI, 2022)Soil salinity is one of the most serious environmental factors affecting crop productivity around the world. We used a morpho-physiological approach to investigate the salt responses of four Tunisian natural populations ... -
Analysis of the fragmented legal regime pertaining to rehabilitation measures for wetlands: A South African perspective – part 1
(WIT Press, 2022)Wetlands are disappearing and it is an international dilemma. Many efforts have been made to ensure its protection and conservation, including rehabilitation. Rehabilitation measures have been adopted in policies of ... -
Antenna beam characterization for the global 21-cm experiment LEDA and its impact on signal model parameter reconstruction
(Oxford University Press, 2022)Cosmic dawn, the onset of star formation in the early universe, can in principle be studied via the 21-cm transition of neutral hydrogen, for which a sky-averaged absorption signal, redshifted to MHz frequencies, is predicted ... -
Fabrication, characterization, and photovoltaic performance of titanium dioxide/metal-organic framework composite
(Elsevier, 2022)The titanium dioxide-metal-organic framework (TiO2−MOF) composite was prepared using the sol-gel method for photovoltaic applications. Raman analyses showed the presence of MOF clusters in the TiO2 sol-gel network. Using ... -

(MDPI, 2022)We would like to thank F. Pallotti and his colleagues for their positive comments [1] on our SWOT analysis of the strengths, weaknesses, threats and opportunities of the sixth edition of the WHO manual on semen analysis ... -
Biosynthesis of silver nanoparticles using Bersama engleriana fruits extracts and their potential inhibitory effect on resistant bacteria
(MDPI, 2022)The absence of novel, safe, and effective bactericide is an urgent concern worldwide and remains a challenge in scientific communities. The unique proprieties of silver nanoparticles (SNPs) synthesized from plant extracts ... -
Definitions matter: Including the socio-economic dimension as a critical component of SADC circular economy definitions
(Academy of Science of South Africa, 2022)Globally, scholars agree that there is a lack of clarity on the notion of the circular economy (CE) and a lack of consensus on a foundational definition of the term. Some definitions place greater emphasis on the socio-economic ... -
Transitioning towards a circular bioeconomy in South Africa: Who are the key players?
(Academy of Science of South Africa, 2022)The transition towards a circular economy is becoming a priority in many countries globally. However, the circular bioeconomy has received relatively less attention. In South Africa, the valorisation of organic waste is a ... -
